The Modified Harborview Risk Score Successfully Predicts Mortality after Ruptured Abdominal Aortic Aneurysm Repair.

Background: The traditional Harborview Risk Score uses 4 criteria to predict mortality after surgical repair of ruptured abdominal aortic aneurysms (rAAAs): preoperative minimum systolic blood pressure <70 mm Hg, creatinine >2.0 mg/dL, age >76 years and preoperative arterial pH < 7.2.

Rechallenge With High-Dose Methotrexate After Treatment With Glucarpidase in Adult Patients With Lymphoma.

Purpose: Limited evidence exists regarding methotrexate (MTX) resumption after patients with lymphoma receive glucarpidase for toxic MTX levels and acute kidney injury (AKI).

Methods: This retrospective review included adults with lymphoma treated with glucarpidase after MTX at Mayo Clinic between January 31, 2020, and October 10, 2022. Descriptive statistics summarize patient characteristics and clinical outcomes.

Area Deprivation Index is not predictive of worse outcomes after open lower extremity revascularization.

Objective: Prior research has shown that socioeconomic status (SES) is associated with higher rates of diabetes, peripheral vascular disease, and amputation. We sought to determine whether SES or insurance type increases the risk of mortality, major adverse limb events (MALE), or hospital length of stay (LOS) after open lower extremity revascularization.

Methods: We conducted a retrospective analysis of patients who underwent open lower extremity revascularization at a single tertiary care center from January 2011 to March 2017 (n = 542).

Recurrent upper extremity arterial thrombosis preceding a diagnosis of COVID-19.

Arterial thrombosis occurs when there is endothelial damage in the setting of hypercoagulability and arterial blood stasis. COVID-19 has been theorized to cause both endothelial damage and promote hypercoagulability by causing an imbalance of clotting factors. In many studies, there have been a large proportion of COVID-19 patients that suffered a thromboembolic event, in both the venous and arterial systems.

High-Dose Methotrexate in Patients With Lymphoma: Predictors of a Complicated Course.

Purpose: High-dose methotrexate (HDMTX; > 500 mg/m) is an important component of lymphoma therapy. Serum MTX monitoring at 48 hours is the standard approach to identify those at increased risk of developing MTX toxicity. Our aim was to characterize the incidence of complications and their association with MTX levels.

Cross-cultural measurement invariance of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short form across ten countries: the application of Bayesian approximate measurement invariance.

Background: The Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) is the most frequently used generic quality of life (QOL) measure in many countries and cultures worldwide. However, no single study has been carried out to investigate whether this questionnaire performs similarly across diverse cultures/countries. Accordingly, this study aimed to assess the cross-cultural measurement invariance of the Q-LES-Q-SF across ten different countries.

Giant visceral artery pseudoaneurysm treated with endovascular transradial coil embolization.

Visceral artery pseudoaneurysms (PSAs) are relatively rare, and cases associated with distal vasculature of the superior mesenteric artery are largely unreported. Visceral artery PSAs, without intervention, can lead to morbidity or mortality from rupture or mesenteric ischemia. Historically, open aneurysmectomy is the gold standard; however, endovascular modalities have emerged as the first-line treatment in patients who are poor surgical candidates and/or have unfavorable anatomy.

Assessment and source quantification of heavy metal(loid)s in surface water using multivariate analyses from the Saigon River, Vietnam.

The metal concentration in surface water of a river could be affected by season, position, and oceanic process such as tide. The current study aimed to (1) examine the heavy metal(loid) concentration in surface water from the Saigon River as affected by the combination of season, tide, and position and (2) apportion and quantify pollution sources. Ninety-six surface water samples were collected from 13 sites on the River in four campaigns (rainy season + ebb tide, rainy season + flood tide, dry season + ebb tide, and dry season + flood tide).

Anesthesia Type is Associated with Decreased Cranial Nerve Injury in Carotid Endarterectomy.

Background: Anesthesia modalities for carotid endarterectomy continue to vary nationally. We evaluated and compared short-term outcomes after carotid endarterectomy with general anesthesia (GA) and regional anesthesia (RA) in both symptomatic and asymptomatic patients.

Methods: The 2011-2015 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files (PUFs) with merged Vascular Procedure-Targeted PUFs for carotid endarterectomy were queried for patients undergoing carotid endarterectomy.

Paediatric use of antibiotics in children with community acquired pneumonia: A survey from Da Nang, Vietnam.

Aim: To characterise paediatricians' antibiotic-prescribing behaviour when managing community acquired pneumonia.

Methods: We conducted a knowledge and attitudes survey of paediatric doctors practicing at a regional provincial hospital in central Vietnam over a 2-week period (from 12 December 2017 to 29 December 2017).

Results: Of 79 eligible paediatric doctors, 69 (87.

Status postpneumonectomy for pulmonary artery sarcoma.

Primary pulmonary artery sarcoma is a rare disease that has a poor survival prognosis due to misdiagnosis with pulmonary thromboembolism or metastatic embolisation, detailed image findings and complicated surgical procedures. Surgical procedures established for treatment include pneumonectomy and pulmonary endarterectomy. Survival after surgery still remains at 1 year survival of 50%.

Geometrically specific imino complexes of the [Re6(μ3-Se)8]2+ core-containing clusters.

The reactions of nitrile complexes of the [Re(6)(μ(3)-Se)(8)](2+) core-containing clusters, [Re(6)(μ(3)-Se)(8)(PEt(3))(n)(CH(3)CN)(6-n)](2+) [n = 5 (1); n = 4, cis- (2) and trans- (3); n = 0 (4)], with organic azides C(6)H(5)CH(CH(3))N(3) and C(6)H(5)CH(2)N(3) produced the corresponding cationic imino complexes of the general formula [Re(6)(μ(3)-Se)(8)(PEt(3))(n)(L)(6-n)](2+) [L = PhN=CHCH(3): n = 5 (5); n = 4, cis- (6) and trans- (7); n = 0 (8) and L = HN=CHPh: n = 5 (9); n = 4, cis- (10) and trans- (11)]. These novel complexes were characterized by NMR spectroscopy ((1)H and (31)P) and single-crystal X-ray diffraction. A mechanism involving the migration of one of the groups on the azido α-C atom to the α-N atom of the azido complex, concerted with the photo-expulsion of N(2), was invoked to rationalize the formation of the imino complexes.

Cluster-bound nitriles do not click with organic azides: unexpected formation of imino complexes of the [Re(6)(mu(3)-Se)(8)](2+) core-containing clusters.

The reactions of C(6)H(5)CH(CH(3))N(3) with nitrile solvates of the [Re(6)(mu(3)-Se)(8)](2+) core-containing cluster, [Re(6)(mu(3)-Se)(8)(PEt(3))(5)(MeCN)](2+)(1) and cis-[Re(6)(mu(3)-Se)(8)(PEt(3))(4)(MeCN)(2)](2+) (2), afforded the corresponding cationic imino complexes [Re(6)(mu(3)-Se)(8)(PEt(3))(5)(PhN horizontal lineCHCH(3))](2+) (3) and cis-[Re(6)(mu(3)-Se)(8)(PEt(3))(4)(PhN horizontal lineCHCH(3))(2)](2+) (4), respectively. Both compounds were spectroscopically and crystallographically characterized. A mechanism involving a 1,2-shift of one of the groups on the azido alpha-C atom of the cluster-azide intermediate concerted with the photoexpulsion of dinitrogen of the azido ligand is invoked to rationalize the formation of the imino complexes.
