Outpatient elective induction of labour at 39 weeks' gestation (HOME INDUCTION): an open-label, randomised, controlled, phase III, non-inferiority trial.

Background: The increased demand for induction of labour (IOL) at 39 weeks' gestation in normal-risk nulliparous patients creates significant logistical challenges for busy maternity units. A potential innovation is commencing induction by means of outpatient cervical ripening, using either a vaginal prostaglandin preparation (Propess) or an osmotic cervical dilator (Dilapan-S). Methods: A Phase III, open label, single centre non-inferiority trial (EudraCT number 2019-004697-25) randomised healthy nulliparous women who chose elective IOL at 39 weeks to one of three methods of initial cervical ripening, specifically 12 h of Dilapan-S(D12), 24 h of Dilapan-S(D24), or 24 h of Propess(P24) between November 2020 and July 2023. After initial administration of the IOL agent in the hospital, participants returned home for 12 or 24 h, before readmission to complete delivery. The primary outcome was vaginal delivery achieved at any time, and this was compared in a non-inferiority analysis of Dilapan-S compared to Propess, within a 10% non-inferiority margin. Secondary outcomes included pairwise comparisons for each induction agent, and a range of logistical factors, such as time to delivery, the need for an additional cervical ripening agent, and length of hospital stay. Findings: Of the 327 women randomised at 38 weeks, 271 (83%) completed the induction intervention. The D24 and P24 groups showed similarly high rates of vaginal delivery, 75% and 76% respectively. D12 had a lower vaginal delivery rate of 64% and consequently the overall comparison of Dilapan-S to Propess did not demonstrate non-inferiority (difference = -6%, 95% CI = -17%, 5%) because the lower 95% CI exceeded the -10% threshold of non-inferiority. The majority of participants across all groups were delivered by any means within 72 h of starting the induction process, inclusive of time spent at home (89% of the D24 group, 98% of the D12 group, 95% of the P24 group). There were no differences in rates of adverse events between groups. Interpretation: There were similarly high vaginal delivery rates for D24 and P24, with at least 75% of patients successfully delivering vaginally following outpatient cervical ripening, with no significant adverse maternal or neonatal outcomes.

Uncovering phytochemicals quantitative evolution in avocado fruit mesocarp during ripening: A targeted LC-MS metabolic exploration of Hass, Fuerte and Bacon varieties.

Avocado ripening entails intricate physicochemical transformations resulting in desirable characteristics for consumption; however, its impact on specific metabolites and its cultivar dependence remains largely unexplored. This study employed LC-MS to quantitatively monitor 30 avocado pulp metabolites, including phenolic compounds, amino acids, nucleosides, vitamins, phytohormones, and related compounds, from unripe to overripe stages, in three commercial varieties (Hass, Fuerte, and Bacon). Multivariate statistical analysis revealed significant metabolic variations between cultivars, leading to the identification of potential varietal markers. Most monitored metabolites exhibited dynamic quantitative changes. Although phenolic compounds generally increased during ripening, exceptions such as epicatechin and chlorogenic acid were noted. Amino acids and derivatives displayed a highly cultivar-dependent evolution, with Fuerte demonstrating the highest concentrations and most pronounced fluctuations. In contrast to penstemide, uridine and abscisic acid levels consistently increased during ripening. Several compounds characteristic of the Bacon variety were delineated but require further research for identification and role elucidation.

Cu-Catalyzed Enantioselective Borylative Desymmetrization of 1-Vinyl Cyclobutanols and Axial-to-Point Chirality Transfer in a Diastereoconvergent/Stereoretentive Allylation Scenery.

Cu-catalyzed asymmetric allylic borylation of 3,3'-disubstituted 1-vinylcyclobutan-1-ols renders axially chiral allylborane systems, with high asymmetric induction for both enantiomers, by precise selection of the cis or trans substrate. The enantioenriched alkylidenecyclobutanes served as chiral platform to prove the conceptually challenging transference of the axial-to-point chirality through two new stereocenters and one pseudoasymmetric carbon generated via diastereoconvergent allylation of aldehydes, without enantioselective erosion.

Use of resources in elderly patients consulting the emergency department: analysis of the Emergency Department and Elder Needs Cohort (EDEN-21).

The elderly population frequently consults the emergency department (ED). This population could have greater use of EDs and hospital health resources. The EDEN cohort of patients aged 65 years or older visiting the ED allowed this association to be investigated. To analyse the association between healthcare resource use and the characteristics of patients over 65 years of age who consult hospital EDs. We performed an analysis of the EDEN cohort, a retrospective, analytical, and multipurpose registry that includes patients over 65 years of age who consulted in 52 Spanish EDs. The impact of age, sex, and characteristics of ageing on the following outcomes was studied: need for hospital admission (primary outcome) and need for observation, stay in the ED > 12 h, prolonged hospital stay > 7 days, need for intensive care unit (ICU) and return to the ED at 30 days related to the index visit (secondary outcomes). The association was analysed by calculating the adjusted odds ratios (aOR) and their 95% confidence intervals (CI), using a logistic regression model. A total of 25,557 patients with a mean age of 78.3 years were analysed, 45% were males. Of note was the presence of comorbidity, a Charlson index ≥ 3 (33%), and polypharmacy (66%). Observation in the ED was required by 26%, 25.4% were admitted to the hospital, and 0.9% were admitted to the ICU. The ED stay was > 12 h in 12.5% and hospital stay > 7 days in 13.5% of cases. There was a progressive increase in healthcare resource use based on age, with an aOR for the need for observation of 2.189 (95% CI 2.038-2.352), ED stay > 12 h 2.136 (95% CI 1.942-2.349) and hospital admission 2.579 (95% CI 2.399-2.772) in the group ≥ 85 years old. Most of the characteristics inherent to ageing (cognitive impairment, falls in the previous 6 months, polypharmacy, functional dependence, and comorbidity) were associated with significant increases in the use of healthcare resources, except for ICU admission, which was less in all the variables studied. Age and the characteristics inherent to ageing are associated with greater use of structural healthcare resources.

Proteomic profiles of peritoneal fluid-derived small extracellular vesicles correlate with patient outcome in ovarian cancer.

Cancer-derived small extracellular vesicles (sEVs) are capable of modifying the tumor microenvironment and promoting tumor progression. Ovarian cancer (OvCa) is a lethal malignancy that preferentially spreads through the abdominal cavity. Thus, the secretion of such vesicles into the peritoneal fluid could be a determinant factor in the dissemination and behavior of this disease. We designed a prospective observational study to assess the impact of peritoneal fluid-derived sEVs (PFD-sEVs) in OvCa clinical outcome. For this purpose, 2 patient cohorts were enrolled: patients with OvCa who underwent a diagnostic or cytoreductive surgery and nononcological patients, who underwent abdominal surgery for benign gynecological conditions and acted as the control group. Systematic extraction of PFD-sEVs from surgical samples enabled us to observe significant quantitative and qualitative differences associated with cancer diagnosis, disease stage, and platinum chemosensitivity. Proteomic profiling of PFD-sEVs led to the identification of molecular pathways and proteins of interest and to the biological validation of S100A4 and STX5. In addition, unsupervised analysis of PFD-sEV proteomic profiles in high-grade serous ovarian carcinomas (HGSOCs) revealed 2 clusters with different outcomes in terms of overall survival. In conclusion, comprehensive characterization of PFD-sEV content provided a prognostic value with potential implications in HGSOC clinical management.

Traqueotomía versus traqueostomía, la necesidad de una aclaración lexicográfica / Tracheotomy versus tracheostomy, the need for lexicographical clarification

Con frecuencia se usan en el ámbito sanitario los términos traqueotomía y traqueostomía, pudiendo generar dudas entre los propios profesionales sobre qué definición corresponde a cada término o cuál de ellos debe considerarse más correcto en casos concretos. Se ha realizado una búsqueda de los términos «traqueotomía» y «traqueostomía» en los diccionarios generalistas en idioma español del Diccionario de la Real Academia Española (DRAE) y del Diccionario Histórico de la Lengua Española de la Real Academia Española (DHLE), y de los términos en inglés «tracheotomy» y «tracheostomy» en los diccionarios generalistas en idioma inglés del Oxford Dictionary, del Cambridge Dictionary y del Collins English Dictionary. Asimismo, se ha hecho una búsqueda en los diccionarios de términos médicos en español del Diccionario de Términos Médicos de la Real Academia Nacional de Medicina (DTM) y en inglés del Farlex Dictionary. Los términos se buscaron también en el buscador generalista de Internet Google®. Se analizaron las definiciones desde el punto de vista lexicográfico y etimológico. Las definiciones que aparecen en los diccionarios generalistas, tanto en español como en inglés, son imprecisas, limitadas y adolecen de ambigüedad por mezclar indicaciones desactualizadas con criterios alejados de la etimología. Sin embargo, las definiciones en los diccionarios de términos médicos en ambos idiomas están más ajustadas a la etimología. La traqueotomía identifica estrictamente el procedimiento quirúrgico de realización de una apertura en la cara anterior de la tráquea. La traqueostomía identifica la realización de un orificio que comunica la tráquea con el exterior e implica una modificación del tracto aéreo superior al proporcionar una entrada adicional de la vía respiratoria. Solo en las laringectomías totales la traqueostomía es la única vía de entrada al tracto aéreo. Ambos términos pueden utilizarse sinónimamente cuando una traqueotomía culmina con una traqueostomía. No convendrá utilizar el término traqueostomía cuando se produce el cierre de los planos al final del procedimiento y este no resulta en la creación de un estoma. Los traqueostomas pueden ser cualificados con adjetivos de tiempo de permanencia (temporal/permanente), tamaño (grande/pequeño), forma (redondo/elíptico), o profundidad por sí mismos, sin vincularse a ningún tipo de enfermedad o de indicación quirúrgica. No todos los traqueostomas permanentes tienen lugar en laringectomías totales ni tienen sistemáticamente un carácter irreversible.(AU)

In the healthcare field, the terms “traqueotomía” and “traqueostomía” are frequently used, often leading to confusion among professionals regarding the appropriate definition for each term or which one should be considered more correct in specific cases. A search was conducted for the terms “traqueotomía” and “traqueostomía” in general Spanish-language dictionaries such as the Dictionary of the Royal Spanish Academy (DRAE) and the Historical Dictionary of the Spanish Language of the Royal Spanish Academy (DHLE), as well as for the English terms “tracheotomy” and “tracheostomy” in English general dictionaries like the Oxford Dictionary, the Cambridge Dictionary, and the Collins English Dictionary. Additionally, searches were performed in medical dictionaries in both Spanish, specifically the Dictionary of Medical Terms of the National Academy of Medicine (DTM), and English, including the Farlex Dictionary. The terms were also explored using the Google search engine. Definitions were analyzed from both lexicographical and etymological perspectives. Definitions found in general dictionaries, in both Spanish and English, were found to be imprecise, limited, and ambiguous, as they mixed outdated indications with criteria that deviated from etymology. In contrast, definitions in medical dictionaries in both languages were more aligned with etymology. “Traqueotomía” strictly identifies the surgical procedure of creating an opening in the anterior face of the trachea. “Traqueostomía” identifies the creation of an opening that connects the trachea to the exterior, involving a modification of the upper airway by providing an additional entry for the respiratory pathway. “Traqueostomía” becomes the sole means of entry to the airway in total laryngectomies. Both terms can be used synonymously when a traqueotomía culminates in a traqueostomía. However, it is not appropriate to use the term “traqueostomía” when the procedure concludes with the closure of the planes and does not result in the creation of a stoma. Traqueostomas can be qualified with adjectives indicating permanence (temporary/permanent), size (large/small), shape (round/elliptical), or depth, without being linked to any specific disease or surgical indication. Not all permanent traqueostomas are the result of total laryngectomies, and they do not necessarily have an irreversible character systematically.(AU)

Comparison of the MIPS technique versus linear incision with tissue preservation in osseointegrated implants in the Ponto model®.

BACKGROUND AND OBJECTIVES: The surgery of osseointegrated implants has undergone different modifications over the years with the aim of achieving better results and facilitating the surgical technique. Today the most commonly used technique is the linear incision with tissue preservation and placement of the abutment and implant. The long-term success of this technique has served as the basis for the development of the so-called minimally invasive surgical approach (MIPS). This study compares the short-, medium- and long-term results between the classic linear incision technique and the MIPS technique. MATERIAL AND METHODS: A prospective study was conducted on patients who had an osseointegrated implant placed between February 2016 and February 2020. A total of 59 surgeries were performed, 32 surgeries according to the linear incision technique with tissue preservation and 27 with MIPS technique. Outcomes were evaluated at one week, one month and one year. RESULTS: Statistically significant differences were achieved between the 2 groups at one week after surgery. Eighty per cent of the MIPS patients had Holgers grades 0-1 compared to 35% of the linear technique patients (p = 0.001). No statistically significant differences were observed at one month (p = 0.457) and one year (p = 0.228). One case with grade 4 was recorded which resulted in implant extrusion one month after surgery with the MIPS technique. A new osseointegrated implant was placed 2 months after the fall using the same MIPS technique with good results. We were also able to verify that the duration of surgery was much shorter with the MIPS technique and better tolerated in terms of postoperative discomfort by the patient. CONCLUSIONS: In our experience, the MIPS technique is the technique of choice for surgery of osseointegrated Ponto model implants as it is simpler, faster and presents fewer problems in the immediate postoperative period, with similar long-term postoperative results.

The IRELAnD study-investigating the role of early low-dose aspirin in diabetes mellitus: a double-blinded, placebo-controlled, randomized trial.

BACKGROUND: Although aspirin therapy is being increasingly advocated with the intention of risk modification for a wide range of pregnancy complications, women with prepregnancy diabetes mellitus are commonly excluded from clinical trials. OBJECTIVE: The primary aim of this study was to examine the effect of aspirin therapy on a composite measure of adverse perinatal outcome in pregnancies complicated by pregestational diabetes mellitus. STUDY DESIGN: A double-blinded, placebo-controlled randomized trial was conducted at 6 university-affiliated perinatology centers. Women with type 1 diabetes mellitus or type 2 diabetes mellitus of at least 6 months' duration were randomly allocated to 150-mg daily aspirin or placebo from 11 to 14 weeks' gestation until 36 weeks. Established vascular complications of diabetes mellitus, including chronic hypertension or nephropathy, led to exclusion from the trial. The primary outcome was a composite measure of placental dysfunction (preeclampsia, fetal growth restriction, preterm birth <34 weeks' gestation, or perinatal mortality). The planned sample size was 566 participants to achieve a 35% reduction in the primary outcome, assuming 80% statistical power. Secondary end points included maternal and neonatal outcomes and determination of insulin requirements across gestation. Data were centrally managed using ClinInfo and analyzed using SAS 9.4. The 2 treatment groups were compared using t tests or chi-square tests, as required, and longitudinal data were compared using a repeated-measures analysis. RESULTS: From February 2020 to September 2022, 191 patients were deemed eligible, 134 of whom were enrolled (67 randomized to aspirin and 67 to placebo) with a retrospective power of 64%. A total of 101 (80%) women had type 1 diabetes mellitus and 25 (20%) had type 2 diabetes mellitus. Reaching the target sample size was limited by the impact of the COVID-19 pandemic. Baseline characteristics were similar between the aspirin and placebo groups. Treatment compliance was very high and similar between groups (97% for aspirin, 94% for placebo). The risk of the composite measure of placental dysfunction did not differ between groups (25% aspirin vs 21% placebo; P=.796). Women in the aspirin group had significantly lower insulin requirements throughout pregnancy compared with the placebo group. Insulin requirements in the aspirin group increased on average from 0.7 units/kg at baseline to 1.1 units/kg by 36 weeks' gestation (an average 83% within-patient increase), and increased from 0.7 units/kg to 1.3 units/kg (a 181% within-patient increase) in the placebo group, over the same gestational period (P=.002). Serial hemoglobin A1c levels were lower in the aspirin group than in the placebo group, although this trend did not reach statistical significance. CONCLUSION: In this multicenter, double-blinded, placebo-controlled randomized trial, aspirin did not reduce the risk of adverse perinatal outcome in pregnancies complicated by prepregnancy diabetes mellitus. Compared with the placebo group, aspirin-treated patients required significantly less insulin throughout pregnancy, indicating a beneficial effect of aspirin on glycemic control. Aspirin may exert a plausible placenta-mediated effect on pregestational diabetes mellitus that is not limited to its antithrombotic properties.

α-Boryl Carbanions: The Influence of Geminal Heteroatoms in C-C Bond Formation.

The wide applications of alpha-boryl carbanions in selective coupling with organohalides, imines/carbonyls and conjugated unsaturated substrates has become an interesting tool for organic synthesis. Strategically, the inclusion of heteroatoms, such as Si, S, N, F, Cl, Br and I in the alpha position opens a new venue towards multifunctionalities in molecular design. Here, a conceptual and practical view on powerful carbanions, containing α-silicoboron, α-thioboron, α-haloboron and α-aminoboron is given, as well as a prespective on their efficient application for selective electrophilic trapping.

Remote 1,4-Carbon-to-Carbon Boryl Migration: From a Mechanistic Challenge to a Valuable Synthetic Application of Bicycles.

The present paper reports a remote carbon-to-carbon boryl migration via an intramolecular 1,4-B/Cu shift, which establishes an in situ stereospecific electrophilic trap on the alkene moiety. The synthetic application is developed to prepare functionalized cyclopentenes by means of a palladium-catalyzed regioselective intramolecular coupling that completes a strategic cyclopropanation and generates valuable structural bicyclic systems. The mechanism is characterized by DFT (density functional theory) calculations which showed that the 1,4-migration proceeds through an intramolecular, nucleophilic attack of the copper-alkyl moiety on the boron atom bonded to the C(sp2), leading to a 5-membered boracycle structure. The computation of the 1,3- and 1,4-B/Cu shifts is also compared as is the impact of the endo- or exocyclic alkene on the reaction kinetics.

Speeding-up the Determination of Protein-Ligand Affinities by STD NMR: The Reduced Data Set STD NMR Approach (rd-STD NMR).

STD NMR spectroscopy is a powerful ligand-observed NMR tool for screening and characterizing the interactions of small molecules and low molecular weight fragments with a given macromolecule, identifying the main intermolecular contacts in the bound state. It is also a powerful analytical technique for the accurate determination of protein-ligand dissociation constants (KD) of medium-to-weak affinity, of interest in the pharmaceutical industry. However, accurate KD determination and epitope mapping requires a long series of experiments at increasing saturation times to carry out a full analysis using the so-called STD NMR build-up curve approach and apply the "initial slopes approximation". Here, we have developed a new protocol to bypass this important limitation, which allows us to obtain initial slopes by using just two saturation times and, hence, to very quickly determine precise protein-ligand dissociation constants by STD NMR.

Clinical practice guideline of the spanish society of oral surgery for oral surgery in patients with coagulation disorders / Guía de práctica clínica de la sociedad española de cirugía bucal para cirugía oral en pacientes con trastornos de la coagulación

Background: The number of patients treated with coagulation disorders, and more specifically with anticoagulanttherapy, has increased worldwide in recent years due to increased life expectancy in developed countries. Theprotocols for managing this type of patient in oral surgery has varied over recent years, especially after the appear-ance of new direct-acting oral anticoagulants (DOACs). The assessment of risk of bleeding in this type of patientwhen undergoing a surgical procedure continues to be a controversial issue for patients, dentists and general prac-titioners. The objective of this document is to offer recommendations, based on evidence, for decision making forpatients with coagulopathies who require dental surgical intervention. Material and Methods: Based on the indications of the “Preparation of Clinical Practice guidelines in the NationalHealth System. Methodological manual”, we gathered a group of experts who agreed on 15 PICO questions basedon managing patients with coagulation disorders in dental surgical procedures, such as fitting of implants or dentalextractions.Results: The 15 PICO questions were answered based on the available evidence, being limited in most cases due tothe lack of a control group. Two of the PICO questions were answered by the experts with a grade C recommendation,while the rest were answered with grade D.Conclusions: The results of this review highlight the need to undertake well designed clinical trials with controlgroups and with a representative sample size.(AU)

Stereoselective Control of the Cu Activation of ß,ß-Diboryl Acrylates for Allylic Coupling Protocols with Concomitant Lactonization.

The key to a successful C-B activation is to discriminate between two geminal boryl moieties that are exposed to the same reaction conditions. Here we describe a stereoselective C-B activation of ß,ß-diboryl acrylates forming exclusively the (Z)-α-borylalkenyl copper(I) key intermediate, for subsequent allylic alkylation reactions. The new borylated (Z)-skipped dienoates followed a feasible iodo-lactonization sequence for the preparation of borylated lactone cores, which can be used in drug discovery.

Periostin in the relation between periodontal disease and atherosclerotic coronary artery disease: A pilot randomized clinical study.

OBJECTIVE: The aim of this study was to analyze the effects of periodontal treatment on markers of atherosclerotic coronary artery disease and circulating levels of periostin. BACKGROUND: Periostin is necessary for periodontal stability, but it is highly present in atherosclerotic plaques. Treatment of periodontal disease, with low levels of local periostin, is thought to reduce systemic levels of periostin. Thus, this may contribute to cardiovascular health. METHODS: A pilot randomized controlled clinical trial was designed to include patients with severe periodontal disease and history of atherosclerotic coronary artery disease. Samples of gingival crevicular fluid (GCF) and serum were collected before and after periodontal treatment by periodontal surgery or non-surgical therapy. The levels of several markers of inflammation and cardiovascular damage were evaluated including CRP, IFN-γ, IL-1ß, IL-10, MIP-1α, periostin, and TNF-α in GCF and CRP, Fibrinogen, IFN-γ, IL-1ß, IL-6, IL-10, L-Selectin, MIP-1α, Periostin, TNF-α, and vWF in serum. RESULTS: A total of 22 patients with an average of 56 years old were recruited for participating in this study. Twenty of them were male. Most of them (82%) had suffered an acute myocardial event and underwent surgery for placing 1, 2, or 3 stents in the coronary arteries more than 6 months ago but less than 1 year. The treatment of periodontal disease resulted in an overall improvement of all periodontal parameters. Regarding the evaluation of GCF and serum, a significant increase of periostin in the GCF was observed after periodontal surgery. In contrast, although other markers in GCF and serum improved, no significant correlations were found. CONCLUSION: Treatment of periodontal disease through periodontal surgery induces a local and transient increase in the levels of periostin in the gingival crevicular fluid. The effects on systemic markers of inflammation and cardiovascular function have not been confirmed.

Estudios neurofisiológicos en los trastornos del neurodesarrollo: potenciales evocados cognitivos / Neurophysiological studies in neurodevelopmental disorders: event related potentials

Resumen El trastorno por déficit de atención con hiperactividad (TDAH) y el trastorno del espectro autista (TEA) son trastornos del neurodesarrollo cuyo diagnóstico es clínico y con gran variabilidad en la presentación clínica. La posibilidad de identificar y validar biomarcadores en estos trastornos del neurodesarrollo ayudaría no sólo en su diagnóstico sino también a la hora de implementar tratamientos personalizados y mo nitorizar la respuesta al tratamiento. Exploraciones neurofisiológicas como los potenciales evocados cognitivos (PEC), son una de las herramientas más utilizadas para evaluar de forma objetiva y con una alta resolución temporal las funciones cognitivas y proporcionan información sobre los mecanismos neurobiológicos subyacen tes, por lo que constituyen una herramienta de gran utilidad para valorar las alteraciones cognitivas asociadas a los trastornos del neurodesarrollo. Se han utilizado diferentes componentes de los PEC para el estudio de los trastornos del neurodesarrollo, como el componente P300, N400 o el componente N170 como biomarcador de la disfunción social en TEA. Revisamos los principales componentes de los PEC que se han estudiado como herramientas complementarias en el diagnóstico y en la monitorización de los tratamientos en los trastornos del neurodesarrollo.

Abstract Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are neurodevel opmental disorders whose diagnosis is clinical and with great variability in clinical presentation. The possibility of identifying and validating biomarkers in these neurodevelopmental disorders would help not only in their diagnosis, but also when implementing personalized treatments and monitori ng the response to treatment. Neurophysiologi cal examinations such as event related potentials (ERP) are one of the most widely used tools to objectively assess cognitive functions with high temporal resolution and provide information on the underlying neurobiological mechanisms, making them a very useful tool to assess cognitive alterations associated with neurodevelopmental disorders. Different components of the ERP have been used for the study of neurodevelopmental disorders, such as the P300, N400 component or the N170 component as a biomarker of social dysfunction in ASD. We review the main components of ERP that have been studied as complementary tools in the diagnosis and monitoring of treatments in neurodevelopmental disorders.
