Impact of ticagrelor with or without aspirin on total and recurrent bleeding and ischaemic events after percutaneous coronary intervention: a sub-study of the TWILIGHT trial.
No full textIn standard time-to-first event analysis, early aspirin discontinuation followed by ticagrelor monotherapy has been shown to reduce bleeding without increasing ischaemic complications compared with ticagrelor plus aspirin after percutaneous coronary intervention (PCI). We evaluated whether these treatment effects are preserved when recurrent events are considered. In this TWILIGHT trial post-hoc analysis, we assessed the effects of ticagrelor monotherapy on the total number of events that occurred over the 12-month follow-up among 7119 high-risk patients randomized to aspirin or placebo in addition to ticagrelor at 3 months post-PCI if event-free and adherent to treatment. There were 391 patients with at least one Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding (primary endpoint). Of those, 28 (7.2%) had a recurrent event. The total number of BARC 2, 3, or 5 bleeding events was 148 in the ticagrelor monotherapy arm compared with 278 with ticagrelor plus aspirin arm (P Among selected high-risk patients who underwent PCI and completed 3 months of dual antiplatelet therapy followed by ticagrelor with or without aspirin, recurrent bleeding was less common than recurrent ischaemic events over 12 months. Analysis of total events indicates that ticagrelor monotherapy continues to be more effective than ticagrelor plus aspirin in reducing bleeding without a signal of ischaemic harm
Maximal Fat Oxidation During Exercise in Healthy Individuals: Lack of Genetic Association with the <i>FTO</i> rs9939609 Polymorphism
No full text20.500.12530/87873Background/Objectives: Previous studies suggest that there is a genetically determined component of fat oxidation at rest and during exercise. To date, the FTO gene has been proposed as a candidate gene to affect fat oxidation during exercise because of the association of the "at-risk" A allele with different obesity-related factors such as increased body fat, higher appetite and elevated insulin and triglyceride levels. The A allele of the FTO gene may also be linked to obesity through a reduced capacity for fat oxidation during exercise, a topic that remains largely underexplored in the current literature. The aim of this study was to analyze the association between the FTO rs9939609 polymorphism with the rate of fat oxidation during exercise and metabolic syndrome criteria in healthy participants. Methods: A total of 80 healthy participants (41 men and 39 women) underwent comprehensive assessments, including measurements of anthropometric variables, blood pressure and blood measures of fasting glucose, triglycerides, low- and high-density lipoprotein cholesterol (LDL-c and HDL-c), insulin, interleukin-6 (IL-6) and C-reactive protein (CRP) concentrations. Additionally, the Homeostatic Model Assessment (HOMA-IR) was used to evaluate insulin resistance. Peak oxygen uptake (VO2peak) and maximal fat oxidation rate (MFO) were also measured during an incremental cycling test. FTO rs9939609 genotyping (TT, AT, AA) was performed using genomic DNA samples obtained from a buccal swab and measured with PCR. Results: There were 32 participants (40.0%) with the TT genotype; 31 (38.8%) with the AT genotype; and 17 (21.2%) with the AA genotype. Age, body characteristics, VO2peak, blood pressure and blood variables were similar across all three genotypes. However, serum insulin concentration and HOMA-IR were associated with the FTO rs9939609 genotype with higher values in AA with respect to AT and TT participants (
Long-term effectiveness and tolerability of dolutegravir/lamivudine in treatment-naive people with HIV: an analysis of a multicentre cohort at 96 weeks.
No full text20.500.12530/87852To evaluate the long-term effectiveness, persistence and tolerability of dolutegravir (DTG)/lamivudine (3TC), compared with the most frequently prescribed first-line treatment regimens, among antiretroviral-naive people with HIV from CoRIS, a multicentre cohort in Spain, in 2018-23. We used multivariable regression models to compare viral suppression (VS) (HIV RNA viral load Of 2359 participants, DTG/3TC was prescribed in 472 (20.0%), bictegravir/tenofovir alafenamide (TAF)/emtricitabine (FTC) in 1134 (48.1%), DTG + tenofovir disoproxil fumarate/FTC in 300 (12.7%), DTG/abacavir/3TC in 273 (11.6%) and darunavir/cobicistat/TAF/FTC in 180 (7.6%). At 96 weeks from treatment initiation, 94.0% of participants initiating with DTG/3TC achieved VS, and the mean increase in CD4 cell counts was 295.5 cells/μL (95% CI: 269.9-321.1). During the first 96 weeks after DTG/3TC initiation, 9.8% and 1.3% discontinued their initial regimen, overall and due to AEs, respectively. In multivariable analyses, we did not find significant differences in VS or increase in CD4 cell counts among participants initiating with DTG/3TC compared with other regimens. Initiating ART with a regimen other than DTG/3TC was associated with a higher risk of treatment discontinuation, overall and due to AEs. Among treatment-naive people with HIV from this large multicentre cohort, DTG/3TC had similar effectiveness and better persistence and tolerability than those of the most frequently prescribed first-line regimens at 96 weeks
"Short" Versus "Long" Duration of Untreated Psychosis in People with First-Episode Psychosis: A Systematic Review and Meta-Analysis of Baseline Status and Follow-Up Outcomes.
No full text20.500.12530/87858Duration of untreated psychosis (DUP) has been linked to worse mental health outcomes in psychotic disorders. We meta-analytically studied the relationship between "long" vs. "short" DUP and mental health outcomes. This PRISMA/MOOSE-compliant meta-analysis searched for nonoverlapping individual studies from database inception until November 01, 2023, reporting data from author-defined "short"/"long" DUP (according to author's definition) in patients with first-episode psychosis (FEP). We compared differences between "short"/"long" DUP groups at baseline and/or follow-up in continuous and binary outcomes. We conducted random-effects meta-analyses, stratified analyses, heterogeneity analyses, meta-regression analyses, and quality assessment (PROSPERO: CRD42023479321). From 16,055 citations, 34 studies were included (n = 6,425, age = 27.5 ± 7.1 years, males = 60.4%, white = 70.2%, DUP: mean = 60.8 ± 43.8 weeks, median = 52.5, interquartile range = 31.3, 68.0 weeks, follow-up = 19.2 ± 35.0 months). The definition of "short"/"long" varies significantly between the studies. Compared to "short" DUP (mean = 10.2 ± 11.2 weeks), "long" DUP (mean = 58.8 ± 76.4 weeks) was associated with higher baseline Positive and Negative Syndrome Scale (PANSS) negative (k = 14, ES = 0.45, 95%CI = 0.16, 0.74) and Scale for the Assessment of Negative Symptoms (k = 7, ES = 0.29, 95%CI = 0.11, 0.47) scores, lower remission (k = 7, OR = 0.40, 95%CI = 0.24, 0.67) and more suicide attempts (k = 4, OR = 2.01, 95%CI = 1.36, 2.96). At follow-up, compared to "short" DUP, "long" DUP was associated with lower Global Assessment of Functioning (k = 4, ES = -0.63, 95%CI = -0.83, -0.43) and higher PANSS negative subscale scores (k = 5, ES = 0.66, 95%CI = 0.05, 1.27). In FEP, longer DUP is related to greater baseline negative symptoms, less remission, and more suicide attempts, as well as greater postbaseline negative symptom severity and functional disability. To what degree longer DUP contributes to poorer outcomes or whether DUP only correlates with these outcomes requires further study. A greater consensus on the definition of long DUP is needed to make comparisons between studies more feasible

Digestive pseudopolyposis as a form of presentation of digestive metastases of primary gastric leiomyosarcoma.
No full text20.500.12530/87910A 71-year-old male was diagnosed with gastric leiomyosarcoma in 2020 after biopsies of an ulcerated gastric lesion. Despite oncological treatment, he presented bone, liver and lung progression. Fourth line treatment with Pazopanib was started in 2022 with no evidence of intestinal or peritoneal metastases. He was attended in the Emergency Department in February 2023 due to symptoms of gastrointestinal bleeding with clinical and analytical repercussion with hemoglobin 5.8g/dl. Initially he presented hematemesis and subsequently hematochezia. An upper and lower endoscopic study was performed, revealing multiple sessile polypoid lesions with an irregular mucosal pattern of between 5-30 mm distributed throughout all explored sections at the gastric, duodenal and colic mucosal; some of them ulcerated with fibrin deposits on the surface and signs of recent hemostasis. The histological study demonstrated infiltration by spindle-shaped mesenchymal cells with atypical nuclei, a Ki-67 proliferation index >80%, and an immunohistochemical profile consistent with digestive metastases of primary gastric leiomyosarcoma. CT scan was performed confirming tumor progression with pulmonary, digestive, hepatic, bone, muscle and peritoneal dissemination of gastric leiomyosarcoma
"The Triptan's Hangover": A Multicentric Cross-sectional Observational Study of the Adverse Events of Triptans in Patients With Migraine.
No full text20.500.12530/87857The emergence of triptans represented a breakthrough in the treatment of migraine, but in clinical practice, patients describe symptoms that resemble those of a hangover after taking them. We propose the use of the Hangover Symptoms Scale (HSS) to evaluate this syndrome in patients that take triptans, which may help identify patients at higher risk of presenting these adverse effects that may interfere with therapeutic compliance.A cross-sectional observational pilot study with prospective data collection through a clinical-demographic questionnaire and the HSS was carried out on patients with migraine treated in headache units in 3 tertiary hospitals in Madrid.Sixty-six patients were included in the study. The median HSS was 4 and all symptoms were present in at least 15% of the patients, with difficulty to concentrate being the most frequent (57.6%). No significant differences were found between the presence of a higher HSS score and the sociodemographic characteristics of the patient or his migraine. The presence of aura was associated with a higher percentage of trembling (P = 0.029) and fatigue (nonvisual, polymodal auras; P = 0.017).According to our study, triptans are responsible for a set of symptoms overlapping with those that occur during a hangover. Therefore, we propose that the HSS could be a useful tool for the evaluation and quantification of these effects in patients receiving triptans. In addition, we found that clinical features could be more frequently associated with the appearance of these adverse effects that, however, are not related to any particular patient profile

Assessment of PD-L1 expression and tumour infiltrating lymphocytes in early-stage non-small cell lung carcinoma with artificial intelligence algorithms.
No full textTo study programmed death ligand 1 (PD-L1) expression and tumour infiltrating lymphocytes (TILs) in patients with early-stage non-small cell lung carcinoma (NSCLC) with artificial intelligence (AI) algorithms. The study included samples from 50 early-stage NSCLCs. PD-L1 immunohistochemistry (IHC) stained slides (clone SP263) were scored manually and with two different AI tools (PathAI and Navify Digital Pathology) by three pathologists. TILs were digitally assessed on H&E and CD8 IHC stained sections with two different algorithms (PathAI and Navify Digital Pathology, respectively). The agreement between observers and methods for each biomarker was analysed. For PD-L1, the turn-around time (TAT) for manual versus AI-assisted scoring was recorded. Agreement was higher in tumours with low PD-L1 expression regardless of the approach. Both AI-powered tools identified a significantly higher number of cases equal or above 1% PD-L1 tumour proportion score as compared with manual scoring (p=0.00015), a finding with potential therapeutic implications. Regarding TAT, there were significant differences between manual scoring and AI use (p value This preliminary study supports the use of AI algorithms for the scoring of PD-L1 and TILs in patients with NSCLC
Recommendations for the diagnosis and treatment of anti-neutrophil cytoplasmic autoantibody associated vasculitis
No full text20.500.12530/87857Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities. The use of glucocorticoids, cyclophosphamide and other immunosupressants (such as azathioprine, mychophenolate and methotrexate) was optimised in a series of clinical trials that established the treatment of reference. In recent years, a better knowledge of B lymphocyte function and the role of complement inhibition has transformed the course of this disease while minimising treatment-related adverse effects. This multidisciplinary document of recommendations is based on the consensus of three scientific societies (Internal Medicine, Nephrology and Rheumatology) and on the best available evidence on diagnosis, treatment and follow-up of patients with ANCA-associated vasculitis, including some special situations. The aim of this document is to provide updated information and well-grounded clinical recommendations to practising physicians as to how to improve the diagnosis and treatment outcome of our patients.
