Impact of double stent retriever configuration on first-pass effect in stroke: a multicenter study.
No full text20.500.12530/87908Efficient recanalization of occluded cerebral arteries is crucial in the treatment of acute ischemic stroke. Double stent retrievers have shown the potential to enhance the rates of recanalization on the first pass. This study aims to evaluate the efficacy and safety of the double stent retriever technique and the predictors of achieving first-pass effect in patients with acute ischemic stroke. This prospective multicenter study involved 209 patients from 16 comprehensive stroke centers in Spain. Patients with occlusions in the anterior circulation were treated using the Aperio Hybrid double stent retriever. The study examined various deployment techniques, including simultaneous and sequential deployment and stent configurations, comparing the Y-shaped and parallel configurations. The double stent retriever technique achieved a first-pass effect in 72.7% of cases and a final successful recanalization rate of 99.5%. The Y-shaped configuration was significantly associated with higher recanalization rates on the first pass (OR 2.59, 95% CI 1.18 to 5.68, P=0.02). Procedural complications were mild to moderate in 6.7% and severe in 1.5% of cases, with symptomatic intracranial hemorrhage occurring in 3.3% of patients. At 3 months follow-up, 57.2% of patients achieved a good clinical outcome, with a mortality rate of 15.1%. The findings support the efficacy of the double stent retriever technique, particularly the Y-shaped configuration, in achieving high recanalization rates on the first pass with an acceptable safety profile. This technique may offer clinical benefits for future acute ischemic stroke treatment protocols
Proactive assessment of patient reported outcomes in ovarian cancer studies: a systematic review and call for action in future studies.
No full textThis systematic review aims to evaluate the proactive or real-time assessment of patient reported outcomes in studies involving patients with ovarian cancer undergoing systemic therapy. PubMed, Embase, and Cochrane databases were searched (from database inception until February 2022), and prospective ovarian cancer studies (experimental or observational) that incorporated patient reported outcomes, including quality of life, were included. The primary objective was to assess the ratio of studies incorporating real-time use of patient reported outcomes among those studies performing patient reported outcomes. A secondary objective was to describe the patient reported outcome reporting. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 checklist was followed. Descriptive statistics were used. 3071 articles were screened, with 117 included in the final analysis. Studies were published between 1990 and 2022, and consisted of 35 735 patients (median 140 patients per study; interquartile range 58-415). Median time from patient enrollment initiation to study publication was 7 years (range 1-15). Most studies were experimental/clinical trials (n=93, 79%) followed by observational (n=23, 20%). Therapeutic strategies were assessed in 98% (91/93) of experimental studies, most frequently chemotherapy (n=53, 58%), followed by antiangiogenics or poly-ADP ribose polymerase (PARP) inhibitors (n=8, 9%, each). Patient reported outcomes were the primary endpoint in 7.5% (7/93) and 83% (19/23) of experimental and observational studies, respectively. The ratio of real-time patient reported outcomes assessment/evaluation was 0.9% (1/117). Completion of patient reported outcome questionnaires involves time and effort for patients with ovarian cancer. Responses to these questionnaires were only assessed in real time i
Visual manifestations in giant cell arteritis: identification of risk factors from the ARTESER Registry.
No full text20.500.12530/87858To determine the prevalence and predictive factors of visual manifestations in a large registry of patients with GCA. ARTESER is a large Spanish multicentre registry supported by the Spanish Society of Rheumatology. It includes patients with GCA from across the entire country diagnosed between June 2013 and March 2019. The variables collected at diagnosis were demographics, clinical manifestations (including all visual manifestations), laboratory, temporal artery biopsy, and imaging findings (ultrasound, FDG-PET/CT, MRI angiography, CT angiography). Patients with and without visual involvement were compared in a bivariate analysis. Multivariate logistic regression was performed to determine potential predictive factors of visual manifestations. The study population comprised 1636 GCA patients, of whom 599 (36.6%) presented visual manifestations. Anterior ischemic optic neuropathy was the most frequent (n = 274 of 599; 45.7%) ocular complication. The independent predictors that increased the risk (OR; 95% confidence interval) of visual involvement were older age (1.027; 1.009-1.045) and jaw claudication (1.724; 1.325-2.243). The variables associated with a reduced risk were polymyalgia rheumatica (0.541; 0.414-0.708), fever (0.373; 0.264-0.527), longer symptom duration (0.946; 0.909-0.985) and higher erythrocyte sedimentation rate (ESR) (0.992; 0.988-0.997), common features of patients with large vessel GCA. One-third of GCA patients present visual manifestations at diagnosis. Older age and jaw claudication are independent predictors of visual manifestations, whereas polymyalgia rheumatica, fever, longer symptom duration and high ESR reduce the risk of visual involvement

Prosthetic Joint Infections due to Candida Species: A Multicenter International Study.
No full textProsthetic joint infection (PJI) caused by Candida spp is a severe complication of arthroplasty. We investigated the outcomes of Candida PJI. This was a retrospective observational multinational study including patients diagnosed with Candida-related PJI between 2010 and 2021. Treatment outcome was assessed at 2-year follow-up. A total of 269 patients were analyzed. Median age was 73.0 (interquartile range [IQR], 64.0-79.0) years; 46.5% of patients were male and 10.8% were immunosuppressed. Main infection sites were hip (53.0%) and knee (43.1%), and 33.8% patients had fistulas. Surgical procedures included debridement, antibiotics, and implant retention (DAIR) (35.7%), 1-stage exchange (28.3%), and 2-stage exchange (29.0%). Candida spp identified were Candida albicans (55.8%), Candida parapsilosis (29.4%), Candida glabrata (7.8%), and Candida tropicalis (5.6%). Coinfection with bacteria was found in 51.3% of cases. The primary antifungal agents prescribed were azoles (75.8%) and echinocandins (30.9%), administered for a median of 92.0 (IQR, 54.5-181.3) days. Cure was observed in 156 of 269 (58.0%) cases. Treatment failure was associated with age >70 years (OR, 1.811 [95% confidence interval {CI}: 1.079-3.072]), and the use of DAIR (OR, 1.946 [95% CI: 1.157-3.285]). Candida parapsilosis infection was associated with better outcome (OR, 0.546 [95% CI: .305-.958]). Cure rates were significantly different between DAIR versus 1-stage exchange (46.9% vs 67.1%, P = .008) and DAIR versus 2-stage exchange (46.9% vs 69.2%, P = .003), but there was no difference comparing 1- to 2-stage exchanges (P = .777). Candida PJI prognosis seems poor, with high rate of failure, which does not appear to be linked to immunosuppression, use of azoles, or treatment duration

Early Detection of Cancer and Precancerous Lesions in Persons With HIV Through a Comprehensive Cancer Screening Protocol.
No full text20.500.12530/87908Non-AIDS defining malignancies present a growing challenge for persons with human immunodeficiency virus (HIV, PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment. Acceptability of the procedure was additionally assessed. Cross-sectional analysis of a comprehensive screening protocol to detect precancer and cancer. The readiness of healthcare providers to implement the protocol was evaluated using a validated 4-item survey. Among the 1430 enrolled PWH, 1172 underwent 3181 screening tests, with positive findings in 29.4% of cases, leading to further investigation in 20.7%. Adherence to the protocol was 84%, with HIV providers expressing high acceptability (97.1%), appropriateness (91.4%), and feasibility (77.1%). A total of 145 lesions were identified in 109 participants, including 60 precancerous lesions in 35 patients (3.0%), 9 early-stage cancers in 9 patients (0.8%), and 76 low-risk lesions in 65 subjects (5.5%). Adverse events related to screening occurred in 0.8% of participants, all mild. The overall prevalence of cancer precursors or early-stage cancer was 3.8% (95% confidence interval [CI], 2.74%-5.01%), with highest rates observed in individuals screened for anal and colorectal cancers. The baseline comprehensive cancer screening protocol of the IMPAC-Neo study successfully identified a significant proportion of PWH with precancerous lesions and early-stage cancer. High adherence rates and positive feedback from providers suggest effective implementation potential in real-world healthcare settings
Papillary Craniopharyngioma: An Integrative and Comprehensive Review.
No full textPapillary craniopharyngioma (PCP) is a rare type of tumor, comprising ∼20% of all craniopharyngioma (CP) cases. It is now recognized as a separate pathological entity from the adamantinomatous type. PCPs are benign tumors, classified as World Health Organization grade 1, characterized by nonkeratinizing squamous epithelium. They typically grow as solid and round papillomatous masses or as unilocular cysts with a cauliflower-like excrescence. PCPs primarily occur in adults (95%), with increased frequency in males (60%), and predominantly affect the hypothalamus. Over 80% of these tumors are located in the third ventricle, expanding either above an anatomically intact infundibulum (strictly third ventricle tumors) or within the infundibulo-tuberal region of the third ventricle floor. Clinical manifestations commonly include visual deficits and a wide range of psychiatric disturbances (45% of patients), such as memory deficits and odd behavior. Magnetic resonance imaging can identify up to 50% of PCPs by the presence of a basal duct-like recess. Surgical management is challenging, requiring complex approaches to the third ventricle and posing significant risk of hypothalamic injury. The endoscopic endonasal approach allows radical tumor resection and yields more favorable patient outcomes. Of intriguing pathogenesis, over 90% of PCPs harbor the somatic BRAFV600E mutation, which activates the mitogen-activated protein kinase signaling pathway. A phase 2 clinical trial has demonstrated that PCPs respond well to proto-oncogene B-Raf/MAPK/ERK kinase inhibitors. This comprehensive review synthesizes information from a cohort of 560 well-described PCPs and 99 large CP series including PCP cases published from 1856 to 2023 and represents the most extensive collection of knowledge on PCPs to date
