Background and aims
There is little evidence on the impact of current recommendations on the use of antiplatelet therapy during the perioperative and periprocedural period in our setting. The aim of this study was to analyze the incidence and clinical impact of inappropriate use of antiplatelet therapy in a population of patients undergoing surgery or a diagnostic or therapeutic procedure in “real life” in Spain.
Methods
A prospective multicenter observational study of patients treated with antiplatelet agents requiring intervention was conducted. The incidence of thrombotic and hemorrhagic events at 30 days was analyzed according to peri-intervention management of antiplatelet therapy.
Results
We included 643 patients (31.9% women, 39.0% over 75 years of age), most of them (87.7%) receiving aspirin as antiplatelet therapy at a dose of 100 mg/day. Indications for antiplatelet therapy were ischemic heart disease (44.9%), cerebrovascular disease (21.7%), and peripheral vascular disease (23.0%). Ischemic risk was low in 74.3%, while 51.6% had a low bleeding risk of the intervention. Periprocedural management was considered appropriate in 61.7% of cases. 30-day incidence of the combined primary endpoint of thrombotic events and major bleeding (12.1% versus 5.0%; p = 0.002) and 30-day mortality (5.2% versus 1.5%; p = 0.008) were significantly higher in patients with inappropriate periprocedural management of antiplatelet agents.
Conclusions
Despite current recommendations for the use of antiplatelet drugs in the perioperative/periprocedural period, their implementation in the “real world” remains low. Inappropriate use is associated with an increased incidence of adverse events, both thrombotic and hemorrhagic.

Introduction
Cardiovascular (CV) diseases are among the main causes of death in systemic lupus erythematosus (SLE). Physical activity (PA) and fitness are potential protective factors against the progression of CV risk factors and atherosclerosis.
Aim
To analyze trends over time in PA, sedentary time (ST) and physical fitness and their associations of with traditional and novel markers of CV risk and subclinical atherosclerosis in women with SLE over a 3-year follow-up period.
Methods
In this exploratory study, 77 White Hispanic women with SLE (43.3 ± 13.8 years) with mild disease activity were followed after 3 years (n = 44). HDL and LDL cholesterol (blood samples), BMI and muscle mass (stadiometer and bioimpedance device), blood pressure (BP), pulse wave velocity (PWV, Mobil-O-Graph® monitor), carotid plaques and intima–media thickness (General Electric Medical Systems, LOGQ-6 model) were assessed. PA and ST were measured using triaxial accelerometers. Physical fitness was assessed with the back-scratch, handgrip strength, 30-s chair stand, and 6-min walk, tests.
Results
After 3 years, LDL-c (estimated mean change [est] = 13.77 mg/dL) and PWV (0.13 m/s) increased while diastolic BP (−2.80 mmHG) decreased (all, p < 0.05). In mixed models, 6-min walk test was positively associated with HDL-c (est = 0.07); back scratch (est = 0.33) and chair-stand (est = 1.19) tests were positively associated with systolic BP (all, p < 0.05). No other trends or associations over time were identified (all, p > 0.05).
Conclusions
PA, ST, fitness, and most studied CV risk factors remained stable over time, with only marginal changes in LDL-c, PWV, and diastolic BP. Overall, PA and ST were not longitudinally associated with CV risk factors and subclinical atherosclerosis and contradictory weak associations were found for physical fitness.

After the COVID-19 pandemic, the Omicron variant of the SARS-CoV-2 virus became the dominant lineage in Spain in 2022. Although it possesses a milder pathogenicity than previous variants, it still poses a high risk of causing severe COVID-19 for immunocompromised populations.
A systematic review was conducted to assess the burden of COVID-19 in Spain among immunocompromised patients during the Omicron predominance (1/04/2022–1/04/2023), using PubMed, Cochrane Library, and EPICOVIDEHA between May and July 2023.
The search retrieved 217 articles, of which a total of 5 were included. Upon analysis, it was observed that immunocompromised patients during the Omicron lineage predominance continue to exhibit higher rates of hospitalizations, ICU admissions, and mortality compared to the general population affected by COVID-19. Although the pandemic has ended, the risk persists for immunocompromised individuals.

The soluble urokinase-type plasminogen activator receptor (suPAR) potentially plays a role in immune-thrombosis, possibly by modulating plasmin activity or contributing to chemotaxis in a complex, poorly understood context. The role of suPAR levels in the short-term prognostic of patients with pulmonary embolism (PE) has not been evaluated.
Material and methods
This observational, prospective, single-center study enrolled consecutive patients aged 18 and above with confirmed acute symptomatic PE and no prior anticoagulant therapy. The primary objective was to assess the prognostic capacity of suPAR levels measured at the time of diagnosis in terms of mortality.
Results
Fifty-two patients, with a mean age of 73.8 years (±17), were included, with gender distribution evenly split at 50%. Seven (13.5%) patients died. The ROC curve for mortality yielded an AUC of 0.72 (95% CI 0.48–0.96), with an optimal suPAR cut-off of 5.5 ng/mL. Bivariate analysis for suPAR > 5.5 ng/mL was associated with a crude odds ratio of 10 (95% CI 1.63–61.27; p = 0.01) for 30-day mortality. Survival analysis showed a 30-day mortality hazard ratio of 8.33 (95% CI 1.69–40.99; p < 0.01).
Conclusion
suPAR emerges as a potential biomarker for short-term mortality prediction and holds the potential for enhanced stratification in patients with acute symptomatic PE.

Introduction
Persistent post-COVID olfactory dysfunction continues to be studied due to the controversy in its pathophysiology and neuroimaging.
Materials and methods
The patients had confirmed mild COVID-19 infection with olfactory dysfunction of more than one month of evolution and they were compared to controls with normal olfaction, assessed using the Sniffin’ Sticks Olfactory Test and underwent brain, magnetic resonance imaging (MRI) of the olfactory bulb and olfactory function.
Results
A total of 8 patients and 2 controls participated. The average age of the patients was 34.5 years (SD 8.5), and that of the controls was 28.5 (SD 2.1). The average score in the patients’ olfactory test was 7.9 points (SD 2.2). In brain and olfactory bulb MRI tests, no morphological differences were found. When evaluated by functional MRI, none of the patients activated the entorhinal area in comparison to the controls, who did show activation at this level. Activation of secondary olfactory areas in cases and controls were as follows: orbitofrontal (25% vs 100%), basal ganglia (25% vs 50%) and insula (38% vs 0%) respectively.
Conclusions
There were no observed morphological changes in the brain MRI. Unlike the controls, none of the patients activated the entorhinal cortex in the olfactory functional MRI.
材料与方法 患者确诊为轻度 COVID-19 感染,并伴有超过一个月的嗅觉功能障碍,将他们与嗅觉正常的对照组进行比较,使用嗅棒嗅觉测试(Sniffin' Sticks Olfactory Test)进行评估,并对嗅球和嗅觉功能进行脑部磁共振成像(MRI)检查。患者的平均年龄为 34.5 岁(SD 8.5),对照组的平均年龄为 28.5 岁(SD 2.1)。患者的嗅觉测试平均分为 7.9 分(标准差为 2.2 分)。在大脑和嗅球核磁共振成像测试中,没有发现任何形态学差异。通过功能性核磁共振成像进行评估时,与对照组相比,患者均未激活内嗅区,而对照组则显示激活了内嗅区。病例和对照组的次级嗅区激活情况如下:眶额叶(25% vs 100%)、基底节(25% vs 50%)和岛叶(38% vs 0%)。与对照组不同的是,在嗅觉功能磁共振成像中,没有一名患者激活了内侧皮层。
