Racial and sex disparities in inpatient outcomes of patients with ruptured abdominal aortic aneurysms in the United States.

BACKGROUND: Ruptured abdominal aortic aneurysm (AAA) is a medical emergency that requires immediate surgical intervention. The aim of this analysis was to identify the sex- and race-specific disparities that exist in outcomes of patients hospitalized with this condition in the United States using the National Inpatient Sample (NIS) to identify targets for improvement and support of specific patient populations. METHODS: In this descriptive, retrospective study, we analyzed the patients admitted with a primary diagnosis of ruptured AAA between January 1, 2016, and December 31, 2020, using the NIS database. We compared demographics, comorbidities, and in-hospital outcomes in AAA patients, and compared these results between different racial groups and sexes. RESULTS: A total of 22,395 patients with ruptured AAA were included for analysis. Of these, 16,125 patients (72.0%) were male, and 6270 were female (28.0%). The majority of patients (18,655 [83.3%]) identified as Caucasian, with the remaining patients identifying as African American (1555 [6.9%]), Hispanic (1095 [4.9%]), Asian or Pacific Islander (470 [2.1%]), or Native American (80 [0.5%]). Females had a higher risk of mortality than males (OR, 1.7; 95% confidence interval [CI], 1.45-1.96; P < .001) and were less likely to undergo endovascular aortic repair (OR, 0.70; 95% CI, 0.61-0.81; P < .001) or fenestrated endovascular aortic repair (OR, 0.71; 95% CI, 0.55-0.91; P = .007). Relative to Caucasian race, patients who identified as African American had a lower risk of inpatient mortality (OR, 0.50; 95% CI, 0.37-0.68; P < .001). CONCLUSIONS: In this retrospective study of the NIS database from 2016 to 2020, females were less likely to undergo endovascular intervention and more likely to die during their initial hospitalization. African American patients had lower rates in-hospital mortality than Caucasian patients, despite a higher burden of comorbidities. Future studies are needed to elucidate the potential factors affecting racial and sex disparities in ruptured AAA outcomes, including screening practices, rupture risk stratification, and more personalized guidelines for both elective and emergent intervention.

Venous thromboembolism and cannabis consumption, outcomes among hospitalized patients in the United States: A nationwide analysis.

Venous Thromboembolism (VTE) carries significant clinical implications, and with the rise in cannabis consumption, its potential influence on VTE outcomes warrants investigation. Using the National Inpatient Sample (NIS) database (2016-2019), we analyzed 2,217,184 hospitalized VTE patients. Among these, 1.8 % (38,810) reported cannabis use. We compared demographics, comorbidities, in-hospital outcomes, and quality metrics between cannabis users and non-users with VTE. Cannabis users were chiefly younger males (average age 45 in cannabis users vs. 62 in non-cannabis users) from lower-income brackets. Notably, 5.4 % discharged against medical advice. Although in-hospital mortality was initially lower for cannabis users (2.8 % vs. 5.1 %, OR 0.6, 95 % CI 0.69-0.94, p = 0.008), this difference became non-significant post-propensity-score matching (aOR 0.9, 95% CI 0.72-1.10, p = 0.3). Non-users faced higher in-hospital complications, a trend that persisted post-PSM. Among cannabis users, key mortality predictors were peripheral vascular disease, acute kidney injury, vasopressor use, cardiogenic shock, myocardial infarction, invasive ventilation, and surgical embolectomy. Cannabis users also had a shorter hospital stay (4.2 vs. 5.4 days) and slightly reduced costs ($27,472.95 vs. $31,660.75). The significantly younger age of VTE patients who use cannabis, coupled with the considerable proportion discharging against medical advice, underscores the urgency for tailored care interventions. Additional research is vital to comprehensively understand the interplay between cannabis consumption and VTE outcomes.

Navigating the Challenges of Takayasu Arteritis in a 26-Year-Old Female With Recurrent Chest Pain and a Complex Medical History.

Takayasu arteritis, a rare and complex vasculitis, presents unique diagnostic and management challenges, particularly when encountered in young adults. We present the case of a 26-year-old female with obesity, prediabetes, hepatic steatosis, an adnexal cyst, Helicobacter pylori gastritis, and asthma, who was transferred to our facility due to concerns about aortitis. Her presentation to the referring institution included dysphagia, heartburn that responded to over-the-counter antacids, and recurrent episodes of stabbing chest pain, which had been occurring intermittently since the age of 17. Previous visits to the emergency room for these symptoms had been approached as gastritis, the last being two weeks before this episode. On evaluation, laboratory findings revealed elevated inflammatory markers, and subsequent imaging studies identified extensive circumferential wall thickening of the ascending thoracic aorta, suggestive of aortitis, and the patient was transferred to our institution. The patient's complex medical history and psychosocial stressors, including estrangement from her family, added to the intricacies of her case. Rheumatology consultation was instrumental in guiding further evaluation and management. A diagnosis of Takayasu arteritis with large vessel vasculitis was considered, supported by positron emission tomography-computed tomography findings showing significant metabolic activity in major arteries. The patient was initiated on prednisone therapy, Pneumocystis jirovecii pneumonia prophylaxis, and methotrexate. Ongoing monitoring for disease activity and medication side effects was emphasized. This case highlights the importance of considering rare conditions such as Takayasu arteritis in young adults with atypical presentations and underscores the need for comprehensive, multidisciplinary care that addresses not only the medical aspects but also the psychosocial well-being of the patient.

The midline interlaminar ligament of the spine: An anatomical study.

INTRODUCTION: During routine cadaveric dissection, Simonds et al. in 2019 found a previously undocumented ligament, which they termed the midline interlaminar ligament (MIL), in 24 out of 36 (76.5%) lumbar spinal levels. The MIL is an unpaired ligament located between and distinctly separate from the right and left ligamenta flava (LF). The purpose of this study was to identify the presence or absence of the MIL in the cervical, thoracic, and lumbar spinal regions and obtain detailed measurements of the ligaments' toughness (R) and elastic modulus (E). MATERIALS AND METHODS: Intact preserved cadaveric vertebrae from C2 to the upper sacral region were dissected. Presence or absence of the MIL was documented, and length and width of each MIL were measured in situ. The R and E of the LFs from corresponding spinal segments were found for comparison. RESULTS: At least one MIL was observed in 90.3% (28) of specimens. Eighty-eight MIL's were observed out of 186 cervical intervertebral levels (0.5%), 371 thoracic intervertebral levels (5.9%), and 101 lumbar intervertebral levels (63.4%). The mean width and length of the MIL were 1.21 ± 0.36 and 16.37 ± 2.17 mm, respectively. The mean R of the MIL and the LF were 1390.27 and 2068.04 J m-2 , respectively. The mean E of the MILs and LFs was 46.78 ± 16.65 and 51.15 ± 21.68 MPa, respectively. CONCLUSIONS: Based on our findings, the MIL was present in the majority of vertebrae in our cadaveric population with a predominance for the lumbar region.
