RESUMO

Background: Low fibrinogen levels are associated with an increased risk of perioperative bleeding. However, there is an ongoing debate over the ideal treatment threshold, the benefits of prophylactic supplementation with fibrinogen concentrate, and the best source of fibrinogen. While fibrinogen concentrate supplementation is being widely used to treat bleeding related to acquired haemostatic deficiencies, there is a lack of evidence regarding its dosage, effectiveness, and safety. This systematic review provides an up-to-date summary of the relationship between fibrinogen concentrate supplementation and safety measures in the perioperative care of non-trauma, non-obstetric adult patients. Methods: A comprehensive online search was conducted on PubMed/Medline, EMBASE, Scopus, Web of Science, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials. Results: This systematic review and meta-analysis encompasses ten studies involving 1391 patients. There was a decreased risk of total thromboembolic events in patients treated with fibrinogen compared to the control (OR 0.65, 95% CI 0.43 to 0.98, I2 = 0%). In addition, when fibrinogen was used prophylactically, it resulted in shorter ICU stays (MD -1.50, 95% CI -2.64 to -0.36), when set against its therapeutic use. A sensitivity analysis on cardiovascular surgery studies did not reveal any statistically significant difference. Conclusions: The use of fibrinogen concentrate in the perioperative care of non-trauma and non-obstetric adult patients may lead to potential benefits.

RESUMO

BACKGROUND: POLE mutated endometrial carcinomas may represent a subspecific type of tumors harboring a more favorable prognosis. Grade 3 (G3 or high-grade) endometrioid endometrial carcinomas remain a clinical dilemma, with some tumors behaving as the low-grade counterparts and others presenting a more aggressive behavior. OBJECTIVES: To determine the association between POLE mutational status and the overall-survival (OS) and progression-free-survival (PFS) of patients with G3 endometrioid endometrial cancer (EC). We also aimed to determine the prevalence of POLE mutations in G3 endometrioid EC. METHODS: We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO No: CRD4202340008). We searched the following electronic databases: PubMed/Medline, EMBASE, Cochrane Library, Scopus, and Web of Science. For time-to-event data, the effect of POLE mutation in G3 EC was described using hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). Individual patient data for each study was investigated if available from the study authors. If individual patient data were not available, information regarding time-to-event outcomes was extracted using an appropriate methodology. OS and PFS were analyzed using both one-stage and two-stage approaches, the Kaplan-Meier method, and Cox-proportional hazards models. RESULTS: This systematic review and meta-analysis included 19 studies with 3092 patients who had high-grade endometrioid EC. Patients with POLE mutations had lower risks of death (HR = 0.36, 95% CI 0.26 to 0.50, I2 = 0%, 10 trials) and disease progression (HR = 0.31, 95% CI 0.17 to 0.57, I2 = 33%, 10 trials). The pooled prevalence of POLE mutation was 11% (95% CI 9 to 13, I2 = 68%, 18 studies). CONCLUSION: POLE mutations in high-grade endometrioid EC are associated with a more favorable prognosis with increased OS and PFS.

RESUMO

BACKGROUND: Clinical trials often use digital technologies to collect data continuously outside the clinic and use the derived digital endpoints as trial endpoints. Digital endpoints are also being developed to support diagnosis, monitoring, or therapeutic interventions in clinical care. However, clinical validation stands as a significant challenge, as there are no specific guidelines orienting the validation of digital endpoints. OBJECTIVE: This paper presents the protocol for a scoping review that aims to map the existing methods for the clinical validation of digital endpoints. METHODS: The scoping review will comprise searches from the electronic literature databases MEDLINE (PubMed), Scopus (including conference proceedings), Embase, IEEE (Institute of Electrical and Electronics Engineers) Xplore, ACM (Association for Computing Machinery) Digital Library, CENTRAL (Cochrane Central Register of Controlled Trials), Web of Science Core Collection (including conference proceedings), and Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports. We will also include various sources of gray literature with search terms related to digital endpoints. The methodology will adhere to the Joanna Briggs Institute Scoping Review and the Guidance for Conducting Systematic Scoping Reviews. RESULTS: A search for reviews on the existing evidence related to this topic was conducted and has shown that no such review was previously undertaken. This review will provide a systematic assessment of the literature on methods for the clinical validation of digital endpoints and highlight any potential need for harmonization or reporting of methods. The results will include the methods for the clinical validation of digital endpoints according to device, digital endpoint, and clinical application goal of digital endpoints. The study started in January 2023 and is expected to end by December 2023, with results to be published in a peer-reviewed journal. CONCLUSIONS: A scoping review of methodologies that validate digital endpoints is necessary. This review will be unique in its breadth since it will comprise digital endpoints collected from several devices and not focus on a specific disease area. The results of our work should help guide researchers in choosing validation methods, identify potential gaps in the literature, or inform the development of novel methods to optimize the clinical validation of digital endpoints. Resolving these gaps is the key to presenting evidence in a consistent way to regulators and other parties and obtaining regulatory acceptance of digital endpoints for patient benefit.

RESUMO

Interstitial lung disease occurs in up to 25% of patients with Sjögren's syndrome and 2% - 8 % of patients with systemic lupus erythematosus. Corticosteroid therapy remains the main treatment for systemic lupus erythematosus. However, it can be associated with several neuropsychiatric disorders especially with prednisolone at a dose of more than 40 mg/day. We present the case of a 51-year-old patient with systemic lupus erythematosus and secondary Sjögren's syndrome with severe pulmonary involvement four years after the diagnosis. Chest computed tomography revealed neofibrosis and ground glass appearance pattern. After increasing the dose of prednisolone to 60 mg/day, the patient presented a manic episode. There was need of hospitalization and the situation was considered to be secondary to corticosteroids at high doses. Central neurological involvement by organic disease was excluded. We introduced monthly perfusion of cyclophosphamide for six months and later started mycophenolate mofetil 2 g/day, reducing prednisolone to 10 mg/day and maintaining hydroxychloroquine 400 mg/day, with control of disease activity.


A doença intersticial pulmonar ocorre em até cerca de 25% dos doentes com síndrome de Sjögren e em 2% - 8% dos doentes com lúpus eritematoso sistémico. Os corticosteróides permanecem como pilar de tratamento do lúpus eritematoso sistémico mas podem associar-se a complicações neuropsiquiátricas, sobretudo com doses de prednisolona superiores a 40 mg/dia. Apresentamos o caso de uma doente de 51 anos com síndrome depressiva, lúpus eritematoso sistémico e síndrome de Sjögren secundária que desenvolveu envolvimento pulmonar grave evidente quatro anos após o diagnóstico, com tomografia computadorizada de tórax a revelar padrão de neofibrose e vidro despolido. Com o aumento da prednisolona para 60 mg/dia a doente iniciou um quadro maníaco com necessidade de internamento e que foi admitido no contexto de corticoterapia em dose elevada. Foi excluído envolvimento neurológico central por doença orgânica. Iniciou ciclofosfamida endovenosa mensal durante seis meses seguida de micofenolato de mofetil, tendo-se reduzido prednisolona até 10 mg/dia e mantido hidroxicloroquina 400 mg/dia, com controlo da atividade da doença.
