The first Neolithic boats in the Mediterranean: The settlement of La Marmotta (Anguillara Sabazia, Lazio, Italy).

Navigation in the Mediterranean in the Neolithic is studied here through the boats that were used, the degree of technical specialisation in their construction and, above all, their chronology. After a brief explanation of the exceptional site of La Marmotta, the characteristics and chronology of the five canoes found at the settlement and one of the nautical objects linked to Canoe 1 are discussed. This will allow a reflection on the capability of Neolithic societies for navigation owing to their high technological level. This technology was an essential part in the success of their expansion, bearing in mind that in a few millennia they occupied the whole Mediterranean from Cyprus to the Atlantic seaboard of the Iberian Peninsula.

Biomedical Applications of the Biopolymer Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV): Drug Encapsulation and Scaffold Fabrication.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a biodegradable and biocompatible biopolymer that has gained popularity in the field of biomedicine. This review provides an overview of recent advances and potential applications of PHBV, with special emphasis on drug encapsulation and scaffold construction. PHBV has shown to be a versatile platform for drug delivery, offering controlled release, enhanced therapeutic efficacy, and reduced side effects. The encapsulation of various drugs, such as anticancer agents, antibiotics, and anti-inflammatory drugs, in PHBV nanoparticles or microspheres has been extensively investigated, demonstrating enhanced drug stability, prolonged release kinetics, and increased bioavailability. Additionally, PHBV has been used as a scaffold material for tissue engineering applications, such as bone, cartilage, and skin regeneration. The incorporation of PHBV into scaffolds has been shown to improve mechanical properties, biocompatibility, and cellular interactions, making them suitable for tissue engineering constructs. This review highlights the potential of PHBV in drug encapsulation and scaffold fabrication, showing its promising role in advancing biomedical applications.

Bloodstream Infection in Children With Epidermolysis Bullosa.

BACKGROUND: Epidermolysis bullosa (EB) is frequently complicated by skin infection, which can lead to bacteremia. However, bloodstream infections (BSI) in patients with EB have not been well described. METHODS: Retrospective study of BSI in children 0-18 years with EB from a national reference unit in Spain, in 2015-2020. RESULTS: Among 126 children with EB, we identified 37 BSI episodes in 15 patients (14 recessive dystrophic EB, 1 junctional EB). The most frequent microorganisms were Pseudomonas aeruginosa (n = 12) and Staphylococcus aureus (n = 11). Five P. aeruginosa isolates were ceftazidime-resistant (42%), 4 of which were also resistant to meropenem and quinolones (33%). As for S. aureus , 4 (36%) were methicillin-resistant and 3 (27%) clindamycin-resistant. In 25 (68%) BSI episodes skin cultures had been performed in the previous 2 months. The most frequent isolates were also P. aeruginosa (n = 15) and S. aureus (n = 11). In 13 cases (52%), smear and blood cultures grew the same microorganism, with the same antimicrobial resistance pattern in 9 isolates. Twelve patients (10%) died during follow-up (9 RDEB and 3 JEB). BSI was the cause of death in 1 case. In patients with severe RDEB, a history of BSI was associated with higher mortality (OR 6.1, 95% CI: 1.33-27.83, P = 0.0197). CONCLUSIONS: BSI is an important cause of morbidity in children with severe forms of EB. The most frequent microorganisms are P. aeruginosa and S. aureus , with high rates of antimicrobial resistance. Skin cultures can help guide treatment decisions in patients with EB and sepsis.

Multiply charged ion profiles in the UHPLC-HRMS analysis of palytoxin analogues from Ostreopsis cf. ovata blooms.

Analogues of palytoxin (PLTX), one of the most potent marine biotoxins, are produced by some species of the marine dinoflagellates of the genus Ostreopsis. The proliferation of these species in different coastal zones represents a potential threat of seafood poisoning in humans because the produced toxins can be transferred through marine food webs. Thus, the determination of the concentration of PLTX analogues (ovatoxins-OVTXs, ostreocins-OSTs and isobaric PLTX) in different matrices (seawater, marine fauna, etc.) is necessary to protect human health. This study is addressed to overcome some of the challenges that the chemical complexity of these molecules poses to their quantification by ultra-high-performance liquid chromatography high-resolution mass spectrometry-based techniques (UHPLC-HRMS). In particular, the mass spectra of the palytoxin analogues show the presence of a large number of ions (including mono- and multiply charged ions) whose nature, relative abundances and behavior can lead to quantitation errors if the correct ions are not selected. In this work, the variability of the PLTX and OVTX profiles under different instrument conditions, including the use of diverse electrospray generation sources and different quantitation methods, is studied. Moreover, the extraction protocol in seawater containing Ostreopsis sp. ovata cells is also evaluated. The use of a heated electrospray operating at 350 °C and a quantitative method including ions from different multiply charged species provides a more robust and reliable method for overcoming the problems due to the variability in the toxin's mass spectrum profile. A single MeOH : H2O (80 : 20, v/v) extraction is proposed as the best and reliable procedure. The overall method proposed was applied to quantify OVTXs (-a to -g) and iso-PLTX along the 2019 Ostreopsis cf. ovata bloom. The cells contained a total toxin concentration of up to 20.39 pg per cell.

Distribution and ten-year temporal trends (2009-2018) of perfluoroalkyl substances in gull eggs from Spanish breeding colonies.

Gull eggs are excellent bioindicators of environmental pollution as reflect the contamination levels of coastal areas, especially of persistent and bioacumulative compounds such as perfluoroalkyl substances (PFAS). This study aims to evaluate the geographical distribution and 10-year temporal trends (2009-2018) of 17 PFAS in eggs of two gull species (Larus michahellis and Larus audouinii) from 5 main Spanish colonies. ∑PFAS ranged from 13.7 ± 5.9 to 164 ± 17 ng g-1 wet weight and higher concentrations were observed in L. audouinii than in L. michahellis. Perfluorooctane sulfonate (PFOS) was the predominant compound in all samples, followed by perfluoroundecanoic acid (PFUnA) and perfluorotridecanoic acid (PFTriDA). Perfluorododecanoic acid (PFDoA), perfluorodecanoic acid (PFDA) and perfluorooctanoic acid (PFNA) were also found in all studied areas but at lower concentrations, while perfluorooctanoic acid (PFOA) was only detected in the Medes Islands. Principal Component Analysis revealed the co-occurrence of the 6 detected PFAS, and differentiated samples from Ebro Delta and Medes Islands, both located in the North-Eastern Mediterranean Sea, with high contribution of all PFAS, from Chafarinas and Atlantic Islands with lower concentration levels and variability. Also, different patterns were observed among colonies, suggesting the fish-based diet plays an important role in PFAS bioaccumulation. In all colonies, except for the Medes Islands, ∑PFAS decreased through the 10-year study period, with PFOS, PFUnA, and PFTriDA showing a significant concentration reduction in a colony-specific manner. This study demonstrates the usefulness and importance of continuous systematic long-term monitoring to determine the geographical distribution and temporal variations of PFAS in marine protected areas using gull eggs as bioindicators of environmental pollution.

Healthcare experience among patients with type 2 diabetes: A cross-sectional survey using the IEXPAC tool.

Aim: To assess the experience with health care among patients with type 2 diabetes (T2DM) and to evaluate patients' demographic variables and healthcare-related characteristics which may affect their experience. Methods: A cross-sectional survey was delivered to T2DM adults. Patient experiences were assessed with the 'Instrument for Evaluation of the Experience of Chronic Patients' (IEXPAC) questionnaire, a validated 12-item survey, which describes patient experience within the last 6 months (items 1-11) and hospitalization in the last 3 years (item 12), with possible scores ranging from 0 (worst) to 10 (best experience). Results: A total of 451 T2DM patients responded to the survey (response rate 72.3%; mean age 69.5 ± 10.1 years, 67.8% men). The mean overall IEXPAC score was 5.92 ± 1.80. Mean scores were higher for productive interactions (7.92 ± 2.15) and self-management (7.08 ± 2.27) than for new relational model (1.72 ± 2.01). Only 32.8% of patients who had been hospitalized in the past 3 years reported having received a follow-up call or visit after discharge. Multivariate analyses identified that regular follow-up by the same physician and follow-up by a nurse were associated with a better patient experience. Continuity of healthcare score was higher only in those patients requiring help from others. Conclusions: The areas of T2DM care which may need to be addressed to ensure better patient experience are use of the Internet, new technologies and social resources for patient information and interaction with healthcare professionals, closer follow-up after hospitalization, and a comprehensive multidisciplinary approach with regular follow-up by the same physician and a nurse.

Analysis of Dechlorane Plus and related compounds in gull eggs by GC-HRMS using a novel atmospheric pressure photoionization source.

Here, a new gas chromatography-atmospheric pressure photoionization-high-resolution mass spectrometry (GC-APPI-HRMS) method combined with selective pressurized liquid extraction (sPLE) has been developed for the selective determination of Dechlorane Plus (DP) and its related compounds in gull egg samples used as a bioindicator of contamination. To the best of our knowledge, this is the first time these compounds have been analyzed by GC-MS using atmospheric pressure photoionization (APPI). Negative ion dopant-assisted APPI using vapors of diethyl ether and a source temperature of 250 °C provided high ionization efficiencies and mass spectra characterized by intense in-source fragment ions as well as the presence of molecular ion and characteristic cluster ions containing oxygen atoms in their chemical structure. This made it possible to improve the selectivity in the determination of these compounds compared to that obtained with traditional GC-MS ion sources. Under optimized conditions, the sPLE GC-APPI-HRMS (Orbitrap) method provided high recoveries (> 91%), good precisions (RSD% < 12%), and low method limits of detection (0.1-3.5 pg g-1 wet weight). The developed methodology has been applied to the determination of DP and related compounds in eggs of two gull species (L. michahellis and L. audouinii) from several Spanish protected areas. The results obtained showed significant differences in the DP concentration profiles in eggs from different gull breeding locations and between gull species of the same protected area. These results demonstrated the good performance of the GC-APPI-HRMS system to achieve a selective and sensitive determination of DP and related compounds in complex environmental samples.

Diffuse leptomeningeal glioneuronal tumour: where to biopsy? Case report and literature review.

PURPOSE: Diffuse leptomeningeal glioneuronal tumour (DLGT) is an infrequent entity. Diagnosis is made with biopsy but with so few cases described management, prognosis remains undefined. There are not currently any articles regarding most effective place to biopsy. METHODS: Current literature review and introduction of the case of a 3-year-old male presenting at the emergency room with irritability, vomiting and nuchal rigidity. A head CT was made showing tetraventricular enlargement and a posterior fossa cyst. RESULTS: Patient underwent urgent ventriculoperitoneal shunting surgery with complete symptomp resolution. Brain MRI showed diffuse leptomeningeal enhancing, predominantly in basal cisterns, and multiple cystic-solid lesions along the neural axis. After ruling other conditions, a biopsy among intraoperative samples, was obtained of a PET positive gadolinium spinal enhancing lesion at D8 level, with the final diagnosis of DLGT. CONCLUSION: DLGT can present as acute hydrocephalus. Biopsy stablishes the diagnosis but the place to take the sample can be difficult to select. Our experience suggests that PET-CT and intraoperative biopsy analysis can improve the effectivity of a representative sample.

Estudio comparativo de la ecografía Doppler frente a la biopsia de arteria temporal en el diagnóstico de la arteritis de células gigantes / A comparative study of doppler ultrasound against temporal artery biopsy in the diagnosis of giant cell arteritis

INTRODUCCIÓN: La arteritis de células gigantes (ACG) es una vasculitis que afecta a arterias de mediano y gran calibre. La biopsia de la arteria temporal es la técnica diagnóstica de elección. Atendiendo a la demanda asistencial que supone, pretendemos evaluar la utilidad de la ecografía Doppler en los pacientes con sospecha de ACG, su sensibilidad y especificidad como prueba diagnóstica y si puede suplir a la biopsia. MATERIALES Y MÉTODOS: Se ha realizado un estudio prospectivo de 57 pacientes entre febrero de 2015 y julio de 2016, que han sido diagnosticados con exploración mediante ecografía Doppler y biopsia de arteria temporal. RESULTADOS: Fueron incluidos 57 pacientes, de los cuales 3 fallecieron durante el seguimiento y una paciente fue excluida del estudio al negarse a la biopsia. Otros 21 pacientes fueron diagnosticados de ACG por un especialista reumatólogo tras un mínimo de 6 meses de seguimiento. Presentaron ecografía positiva 22 pacientes, de los cuales 8 fueron diagnosticados de ACG y 4 de polimialgia reumática. En nuestro estudio, la sensibilidad de la ecografía es del 42,6% y la especificidad es del 65,7%. Otros 19 pacientes presentaron biopsia positiva: todos ellos fueron diagnosticados de ACG. La biopsia presentó una sensibilidad de un 73,7% y una especificidad de un 100%. CONCLUSIONES: Según nuestro estudio, la utilidad de la ecografía es limitada y son necesarias nuevas investigaciones para determinar su papel en esta entidad

BACKGROUND: Giant cell arteritis (GCA) is a vasculitis that affects medium- and large-sized arteries. Temporal artery biopsy is the gold standard for diagnosis. In view of the high demand for temporal biopsies, the purpose of this study is to evaluate the usefulness of Doppler ultrasonography in patients with suspected giant cell arteritis, to determine its sensitivity and specificity as a diagnostic test and to determine whether it would be possible to substitute biopsy for ultrasonography. MATERIALS AND METHODS: A prospective study was undertaken including 57 patients from February 2015 to July 2016, who have undergone both ultrasonography and temporal biopsy. RESULTS: A total of 57 patients were included, 3of whom died during the follow-up, and a patient was excluded from the study when she refused to have the biopsy. Another 21 patients were diagnosed with GCA by a rheumatologist after a minimum of 6 months of follow-up and 22 patients had positive ultrasonography, 8 of whom were diagnosed with GCA and 4 with polymyalgia rheumatica. In our study, the sensitivity of ultrasonography was 42.6%, and the specificity was 65.7%. A total of 19 patients had a positive biopsy, all of them were diagnosed with GCA. In our study, the sensitivity of the biopsy was 73.7% and the specificity was 100%. CONCLUSIONS: In view of the data from our study, the usefulness of ultrasonography is questionable, and research about the role of ultrasonography in this disease should be further studied

Analysis of hydroxylated phenylalkylamine stimulants in urine by GC-APPI-HRMS.

A gas chromatography-atmospheric pressure photoionization-high-resolution mass spectrometry (GC-APPI-HRMS) method was developed for the determination of eight phenylalkylamine stimulants in urine samples. Spiked urine samples were hydrolyzed, processed by solid-phase extraction, and derivatized before analysis. Two derivatization reactions were studied: the formation of trimethylsilyl (TMS) derivatives with N-methyl-N-trimethylsilyl trifluoroacetamide (MSTFA) and trimethylsilyl/trifluoroacetyl (TMS/TFA) derivatives with MSTFA and N-methyl-bis (trifluoroacetamide) (MBTFA) as derivatization reagents. Gas chromatography of both derivatives was performed with a 100% dimethylsiloxane column and a good separation of all isomeric compounds was achieved. To maximize the signal of the protonated molecule [M+H]+, the APPI most critical parameters were optimized. Three solvents were tested as dopant agents, with acetone yielding the lower in-source collision-induced dissociation (CID) fragmentation. The acquisition was performed in full scan and product ion scan (parallel reaction monitoring, PRM) using a quadrupole-Orbitrap mass analyzer (35,000 FWHM at m/z 200) in positive ion detection mode. At the optimal working conditions, the full scan method was evaluated for the fulfillment of identification requirements in doping analysis. Selectivity, limits of detection, matrix effect, and precision were estimated to validate the method for confirmation purposes and its applicability was tested by the analysis of spiked samples as well as by the analysis of samples obtained after the administration of some of the compounds to healthy volunteers. Results were compared with those obtained by GC-electron ionization-MS, demonstrating that the GC-APPI-HRMS method improved selectivity and sensibility, achieving lower limits of detection and satisfactory reproducibility.

Staphylococcal toxic shock syndrome in a child with interleukin-17 inhibitor treatment for psoriasis.

A 6-year-old girl presented with fever, skin rash, anuria, and conjunctivitis that rapidly progressed to toxic shock syndrome. Following hospital discharge, she developed a staphylococcal abscess on the lower extremity. She had recently received the first two doses of the interleukin-17 (IL-17) inhibitor secukinumab for resistant plaque psoriasis. IL-17 is known to be essential in host defense against Staphylococcus aureus. To our knowledge, this is the first reported case of staphylococcal toxic shock syndrome (STSS) associated with an IL-17 inhibitor.

Pigment profiles of Spanish extra virgin olive oils by ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry.

This work studies the natural pigment profiles (chlorophylls and carotenoids) of Spanish Extra Virgin Olive Oils (EVOO) produced in different Spanish regions. The simultaneous qualitative and quantitative analysis of EVOO natural pigments has been performed by ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) using atmospheric pressure chemical ionisation (APCI). The results showed a similar natural pigment pattern for all the analysed EVOOs, although the total pigments content differed significantly. Moreover, the chlorophyll/carotenoid ratio was close to 1, while the lutein/ß-carotene ratio was higher than 1, showing that lutein is the most abundant carotenoid in the studied Spanish EVOOs. Data from multivariate statistical approach demonstrated that the olive variety does not discriminate between EVOO samples. However, they were classified based on their origin allowing good differentiation of samples from the Basque Country and Canary Islands from the rest of regions. The results of this study show the differences of the nature and pigments concentration of Spanish EVOO samples, parameters that are of significance for reliable characterisation.

Gynecological Surgery and Its Five Steps Towards Resilience: Minimally Invasive Approach in the COVID-19 Era.

After the declaration of the coronavirus disease 2019 (COVID-19) pandemic, gynecological surgery joins the readjustment process that this great global health crisis implies. In the light of current literature, the five steps towards its resilience are described as below; (1) Dynamic prioritization of surgical indications and reintroduction of elective surgeries: Diverse surgical prioritization lists are published including the most common gynecological pathologies. (2) Minimally invasive surgery through laparoscopy and robotic assistance: Some authors suggest a theoretical but unproven risk of viral transmission during these approaches because of the aerosol generation. These theories are opposed to the well-proven advantages of these approaches compared to open surgery. (3) Optimization of surgical procedures, according to the recommendations of different societies aimed at reducing the dispersion of aerosols and surgical smoke. (4) Clinical, epidemiological and microbiological screening of all patients awaiting prompt surgery: This screening should be adapted to the local alert state. (5) Protection through the reduction of number of persons present in the operating room, and the use of adapted personal protective equipment according to physical proximity to the patient.

La versatilidad del adenovirus humano en el paciente inmunocompetente / The versatility of human adenovirus in the immunocompetent patient

Las infecciones por adenovirus humano se producen especialmente en niños menores de cinco años, se propagan fácilmente y, en algunos casos, son muy contagiosas. La mayoría de las infecciones son autolimitadas, de tipo respiratorio y gastrointestinal, y muchas veces son difíciles de diferenciar de las ocasionadas por otros virus. Excepcionalmente se confunden clínicamente con otros procesos, tal como ocurrió en los dos casos que presentamos. Sería deseable optimizar los métodos diagnósticos para abordar con más precisión estas infecciones y que nos permitan alejarnos de la incertidumbre

Human adenovirus infections occur especially in children under five years old, spread easily and, in some cases, are highly contagious. The majority of infections are self-limited, affecting the respiratory and gastrointestinal systems, and often are difficult to differentiate from those caused by other viruses. Occasionally they are confused in their clinical expression with other processes, as has happened in the two cases we present. It would be desirable to optimize the diagnostic methods in order to address these infections more accurately and to allow us to move away from uncertainty
