    Abstract Posidonia oceanica (L.) Delile meadows are highly productive coastal marine ecosystems that provide multiple ecosystem services. The seagrass is not always the major contributor to total primary production, however, little is known about long-term changes in the composition of primary producers within seagrass meadows. Understanding compositional shifts within the community of primary producers is crucial to evaluate how climate and anthropogenic change affect the functioning of seagrass ecosystems. Here we analysed marker pigment composition in seagrass cores from two bays of the Cabrera Island (Balearic Islands, Spain) to asses long-term changes in phototrophic community composition and production in seagrass meadows, and identify the environmental factors triggering those changes. The proxy dataset was explored using principal component analyses (PCA): one including the pigment dataset to look for associations between producers' groups, and another one combining the pigment dataset with plausible local and global regulatory factors to assess the environmental drivers of change. Analyses of characteristic pigments and morphological fossils (cysts) showed that the abundance of dinoflagellates increased over the last 150-300 years, coeval with a rise in solar irradiance and air temperature. When compared among embayments, pigments from cyanobacteria predominated in seagrass meadows located at Es Port, a sheltered bay receiving higher terrestrial runoff; whereas pigments from diatoms, seagrasses and rodophytes were more common at Santa Maria, an exposed bay with clearer waters. Water depth also played a role in controlling the phototrophic community composition, with greater abundance of diatoms in the shallowest waters (<5 m). Overall, our results suggested that historical and spatial variation in seagrass meadows' phototrophic community composition was influenced by the interaction between local factors (catchment-bay characteristics) and global climate processes (energy influx). Together these patterns forecast how marine primary producers and seagrass ecosystem structure may respond to future global warming.

    Abstract Introduction and objective: The coronavirus disease 2019 (COVID-19) has caused a pandemic of global impact that forced social-political measures to be taken, such as the declaration of the state of alarm in Spain. At the same time, the reorganization of the pediatric medical-surgical activities and infrastructures was carried out, with the consequent suspension of the non-urgent surgical activity of Pediatric Urology. We analyzed the impact of the COVID-19 pandemic on surgical activity in a Pediatric Urology division, as well as surgical complications according to the Clavien-Dindo classification.
    Materials and methods: A systematic review of epidemiological, clinical and surgical data was carried out, including complications and readmissions of all patients operated on in the division of Pediatric Urology within the duration of the state of alarm. Five time periods have been created according to the de-escalation phases.
    Results: Forty-nine surgical procedures were carried out on 45 patients (8 prior to the implementation of the de-escalation phases). High priority pathologies were the most frequent in the first phases, being the ureteropelvic junction (UPJ) obstruction the most prevalent. Four complications were recorded (8.8%), none of them were respiratory.
    Conclusions: The EAU recommendations for the resumption of surgical activity have allowed a correct, safe and gradual transition to the routine surgical activity in Pediatric Urology. The Clavien-Dindo classification is useful and valid for application in this division. No respiratory complications have been reported that could be attributable to the pandemic situation.

    Abstract Posidonia oceanica is a marine phanerogam that buries a significant part of its belowground production forming an organic bioconstruction known as mat. Despite Posidonia seagrass mats have proven to be reliable archives of long-term environmental change, palaeoecological studies using seagrass archives are still scarce. Here we reconstruct four millennia of environmental dynamics in the NE coast of Spain by analysing the carbon and nitrogen stable isotopic composition of P. oceanica sheaths, the proportion of different seagrass organs throughout the seagrass mat and other sedimentological proxies. The palaeoenvironmental reconstruction informs on long-term ecosystem productivity and nutrient loading, which have been linked to global (e.g., solar radiation) and local (e.g., land-use changes) factors. The long-term environmental records obtained are compared with previous palaeoecological records obtained for the area, showing a common environmental history. First, a relative seagrass ecosystem stability at ~4000 and 2000 cal. yr BP. Then, after a productivity peak at ~1400–800 cal. yr BP, productivity shows an abrupt decline to unprecedented low values. The fluctuations in ecosystem productivity are likely explained by increases in nutrient inputs related to human activities – mostly in the bay watershed – concomitantly with changes in total solar radiation. Cumulative anthropogenic stressors after Roman times may have started to affect ecosystem resilience, dynamics and productivity, with more abrupt regime shifts during the last millennium. These results add into recent research showing the potential of seagrass archives in reconstructing environmental change and seagrass post-disturbance dynamics, hence providing unvaluable information for improving the efficiency in managing these key coastal ecosystems.

    Abstract Background/purpose: The aims of this study were to describe our experience in the management of FB aspiration in children, focusing on the eventual association between delay in treatment and the development of complications, and to determine if the incidence of this emergency had decreased in the last 10 years.
    Methods: Retrospective study of children with a diagnosis of FB aspiration managed between 1999 and 2019 at a tertiary care referral hospital. The following data were collected: demographics, clinical presentation, radiological findings, endoscopic technique, type of FB, time elapsed between the aspiration episode and treatment, and complications. Main outcome measures were the rate of complications (intraoperative and long-term) in the cohort of patients with delay in treatment (>72 h), and the incidence of FB aspiration in each of the two historical subgroups of the study.
    Results: The study included 130 patients, 66.2% male, with a median age of 24 months. Cough was the most frequent symptom (76.1%) and unilateral air trapping was the most common radiological finding (48.8%). Removal of FB was performed with rigid bronchoscopy in every case. The most common type of FB was organic (73%) and located in the right bronchial system (47.7%). The global rate of complications was 16.1%. Patients with a delay in treatment beyond 72 h from the aspiration episode showed a statistically significant risk of developing both intraoperative and postoperative complications. Additionally, we have stated that the incidence of FB aspiration in our community has decreased by 44.4% in the last 10 years.
    Conclusions: The incidence of FB aspiration has remarkably decreased in our environment in the last decade. Delay in treatment placed our patients at a significant higher risk of developing complications both during the bronchoscopic procedure and in the long-term.

    Abstract Objectives: The treatment of keloid scars is based on multiple lines of therapy, with varying levels of efficacy(1), and there is currently no single treatment that guarantees cure and prevents recurrence. In the pediatric population, the treatments used are not standardized, and there is insufficient evidence to support efficacy and complications. The objective of this study was to analyze the patients who required brachytherapy as an adjuvant to surgical resection in recurrent keloid scars.
    Materials and methods: A retrospective analysis of patients diagnosed with keloids and undergoing adjuvant brachytherapy in our institution was carried out, while assessing efficacy and implementation in our treatment protocol for keloid scarring.
    Results: After various therapeutic lines, 4 patients aged 9-17 years old with recurrent keloid scars around the ear and eligible for adjuvant brachytherapy - administered after surgical resection, in two sessions - were studied and followed up for up to 18-21 months.
    Conclusions: Despite our limited experience in the use of adjuvant brachytherapy, the results obtained to date support its efficacy, as reported in the literature. We therefore consider its inclusion in the treatment of keloid scars that have recurred after other treatments to be appropriate.
