PURPOSE: A clinical conflict often presented with hip fracture patients is whether to proceed with timely surgery or delay surgery until a formal echocardiogram is conducted. This study aimed to assess the impact of incorporating point-of-care lung and cardiac ultrasound (LUCAS) scans as part of the preoperative assessment for hip fracture patients. METHODS: We recruited 225 consecutive adult patients booked for urgent hip arthroplasty surgery. A LUCAS scan was performed for each patient. The anesthesiologists were asked to provide their anesthetic plans before and after acknowledging the results of the LUCAS scans. The primary endpoint was a composite outcome of changes to the anesthetic plan. The secondary outcomes included anesthesiologists' opinions of the LUCAS scans. RESULTS: One-hundred-ninety-eight patients were included. The majority of LUCAS findings were not severe. A common abnormal finding was hypovolemia (31%). One-hundred-and-six anesthetic management decisions were changed, with 59 of these changes being an escalation of the anesthetic plan, and 47 of these changes being a de-escalation. Eighty-three percent of anesthesiologists agreed that LUCAS affirmed their anesthetic plans and should be an integral part of the perioperative assessment. CONCLUSION: This study found that LUCAS scans did not significantly alter the anesthetic plan for hip fracture patients. Nevertheless, LUCAS scans can rule out severe cardiopulmonary conditions and allow for both escalation and de-escalation of care. In the setting of early hip surgery, LUCAS presents a viable option in selected patients to address the unmet need to allow for both timely surgery and comprehensive patient evaluation.

RéSUMé: OBJECTIF: Une interrogation clinique qui existe souvent avec les patient·es se présentant avec une fracture de hanche est de savoir s'il faut procéder à une intervention chirurgicale rapidement ou retarder la chirurgie jusqu'à ce qu'un échocardiogramme formel soit réalisé. Cette étude visait à évaluer l'impact de l'intégration de l'échographie ciblée pulmonaire et cardiaque (LUCAS, Lung and Cardiac ultrasound) dans le cadre de l'évaluation préopératoire des personnes ayant subi une fracture de la hanche. MéTHODE: Nous avons recruté 225 patient·es adultes consécutif·ves devant bénéficier d'une arthroplastie urgente de la hanche. Une échographie de type LUCAS a été réalisée pour chaque patient·e. On a demandé aux anesthésiologistes de fournir leurs plans anesthésiques avant et après avoir pris connaissance des résultats des échographies de type LUCAS. Le critère d'évaluation principal était un résultat composite des modifications apportées au plan anesthésique. Les critères d'évaluation secondaires comprenaient les opinions des anesthésiologistes sur les échographies de type LUCAS. RéSULTATS: Cent quatre-vingt-dix-huit patient·es ont été inclus·es. La majorité des résultats de l'échographie de type LUCAS n'étaient pas graves. Un résultat anormal courant était l'hypovolémie (31 %). Cent six décisions de prise en charge anesthésique ont été modifiées, 59 de ces changements étant une escalade du plan anesthésique et 47 de ces changements étant une réduction. Quatre-vingt-trois pour cent des anesthésiologistes ont convenu que l'échographie de type LUCAS confirmait leurs plans anesthésiques et devrait faire partie intégrante de l'évaluation périopératoire. CONCLUSION: Cette étude a révélé que les échographies de type LUCAS ne modifiaient pas de manière significative le plan anesthésique pour les patient·es se présentant avec une fracture de hanche. Néanmoins, les échographies de type LUCAS peuvent exclure des affections cardiopulmonaires graves et permettre à la fois d'augmenter ou de réduire les soins périopératoires. Dans le cadre d'une chirurgie précoce de la hanche, l'échographie de type LUCAS présente une option viable chez une patientèle sélectionnée pour répondre à un besoin non satisfait afin de permettre à la fois une chirurgie rapide et une évaluation complète des patient·es.

OBJECTIVES: Rheumatoid arthritis (RA) is associated with an increased prevalence of cardiovascular disease (CVD). Since atherosclerosis development is a gradual process of damage inside the artery wall, and the phenotype-genotype correlation of complex diseases may vary depending on ethnicity, we sought to investigate the influence of clinical features, routine inflammatory markers, and the genetic component of RA on different stages of atherosclerosis in northwestern Colombian patients with RA. METHODS: A group of 140 patients with RA were enrolled in this study. All patients underwent a noninvasive evaluation of endothelial function by flow-mediated vasodilation (FMV) and an assessment of carotid intima-media thickness (IMT) by high-resolution B-mode ultrasonography. The patients were classified into 3 categories: endothelial dysfunction (FMV <5%), increased IMT (0.91-1.29 mm), and plaque (IMT >1.30 mm). The risk of being in each category was assessed by investigating traditional and nontraditional cardiovascular risk factors. For each stage of atherosclerosis development, we searched for nontraditional risk factors that were significantly associated with the stage after adjusting for traditional risk factors and current age. RESULTS: Rheumatoid factor seropositivity was significantly associated with endothelial dysfunction (adjusted odds ratio, AOR = 3.0). A duration of RA >10 years (AOR = 29.0) and being a carrier of an HLA-DRB1 shared epitope allele (AOR = 4.8) were associated with atherosclerotic plaque. No association of extra-articular manifestations, anticyclic citrullinated peptide (anti-CCP3) antibodies, and tumor necrosis factor -308 polymorphism with CVD was found. CONCLUSIONS: Our results reveal the presence of RA-related risk factors for CVD which act independently of traditional risk factors. These factors can be used by clinicians to predict CVD in RA patients, and this data should assist in the development of public health policies in our population for the improvement of patient outcomes.
