Purpose: This study aims to identify and comprehend the management of the most frequent complications in oral surgery that arise from the consumption of multiple drugs. Materials and Methods: A comprehensive review of 23 articles was conducted, focusing on the complications that arise from the consumption of drugs in patients undergoing oral surgery treatment, in addition to the strategies for prevention and treatment. Results: All the reviewed articles offered insightful knowledge into preventing complications through well-defined protocols that encompass both pre- and post-operative measures. These measures include local interventions such as periodontal treatments, dental prophylaxis, and hygiene instructions, as well as systemic approaches like antibiotic prophylaxis and post-surgical antibiotic coverage. Additionally, specific measures like monitoring prothrombin time with the International Normalized Ratio in patients with coagulation disorders, and implementing hemostatic techniques, were also discussed. Conclusion: The most prevalent complications in oral surgery are hemorrhage in anticoagulated patients, infections in immunosuppressed patients, and osteonecrosis in patients who take antiresorptive drugs. Edema, pain, and inflammation are also common post-operative concerns. When managing high-risk patients pharmacologically, it is crucial to provide effective antibiotic coverage both pre- and post-procedure and to utilize minimally invasive dental procedures with local hemostatic measures.

Introduction: A clinical dermatological research was conducted in Spain from 2005 through 2014 as part of the MaIND project with the provinces or centers with the highest number of published articles. However, a low level of evidence in scientific production was confirmed as the overall result. The aim of this study is to update the Spanish clinical dermatological research in bibliometric terms from 2015 through 2021 with comparisons between both periods of time. Material and methods: We conducted a bibliometric study to replicate the methodology used in the article to be updated. We included articles whose corresponding authors’ affiliation was a Spanish dermatological center, which met the criteria for clinical research in dermatology, including a level of evidence ≤ 4. Results: A total of 1,674 out of the 10,199 articles met the inclusion criteria. An interactive map representing quantitative and qualitative indicators calculated for the 2005-2021 is presented here. In the study period, we found an increasing trend both in the number of published articles (P 4, with a positive trend towards more articles having a higher level of evidence (P

Resumen: La falla hepática aguda es un síndrome poco común pero grave, con una incidencia de aproximadamente 2,000 a 3,000 casos por año en América del Norte. Su fisiopatología y curso clínico varían según la causa del daño hepático primario, y puede llevar a una alta morbimortalidad o necesidad de trasplante hepático, a pesar de las terapias disponibles. Este síndrome involucra una activación excesiva del sistema inmunológico con daño en otros órganos, lo que contribuye a su alta tasa de mortalidad. La definición más aceptada incluye daño hepático con encefalopatía hepática y coagulopatía en las últimas 26 semanas en un paciente sin enfermedad hepática previa. Las principales causas son intoxicación por paracetamol, hepatitis viral, lesión hepática inducida por drogas, entre otras. Es crucial identificar la causa, ya que influye en el pronóstico y tratamiento. La supervivencia ha mejorado con medidas de soporte, terapia intensiva, prevención de complicaciones y el uso de medicamentos como la N-acetilcisteína. El trasplante hepático es una opción curativa para casos no respondedores al tratamiento médico, pero la evaluación adecuada del momento para el trasplante es crucial para mejorar los resultados. Factores como la edad del paciente, la causa subyacente y la gravedad de las fallas orgánicas influyen en los resultados y la supervivencia postrasplante. Abstract: Acute liver failure is a rare but serious syndrome, with an incidence of approximately 2,000 to 3,000 cases per year in North America. Its pathophysiology and clinical course vary, depending on the cause of the primary liver injury, and can lead to high morbidity and mortality or the need for liver transplantation, despite available therapies. This syndrome involves excessive activation of the immune system, with damage in other organs, contributing to its high mortality rate. The most accepted definition includes liver injury with hepatic encephalopathy and coagulopathy within the past 26 weeks in a patient with no previous liver disease. The main causes are paracetamol poisoning, viral hepatitis, and drug-induced liver injury, among others. Identifying the cause is crucial, given that it influences prognosis and treatment. Survival has improved with supportive measures, intensive therapy, complication prevention, and the use of medications, such as N-acetylcysteine. Liver transplantation is a curative option for nonresponders to medical treatment, but adequate evaluation of transplantation timing is vital for improving results. Factors such as patient age, underlying cause, and severity of organ failure influence the post-transplant outcomes and survival.

In this study, an environmental and economic assessment of WC-Co coatings deposited by Cold Gas Spray (CGS), Atmospheric Plasma Spray (APS) and High Velocity Oxy Fuel (HVOF) spray technologies is carried out. Using SimaPro LCA software, several environmental impact categories are analyzed to compare their environmental performance. The economic analysis includes capital and operating expenditures. The results have highlighted that all three processes exhibit low environmental impact in terms of CO2 emissions but the performance of the CGS process is heavily influenced by the low deformability of WC-Co, while the APS process is affected by high electricity consumption. In terms of economic analysis, the HVOF process exhibits the best performance, while the CGS process requires most time to deposit the coating, and consequently, it is the process where the workforce component is most significant. These results depend on the fact that CGS might not be the most suitable deposition technique for fabricating WC-Co coatings.

Abstract Germanium is reemerging as a prominent material in the semiconductor field, particularly for electronic applications, photonics, photovoltaics, and thermophotovoltaics. Its combination with III‐V compound semiconductors through epitaxial growth by metal‐organic vapor phase epitaxy (MOVPE) is instrumental and thus, the comprehension of the sequential stages in such epitaxial processes is of great importance. During the deposition of GaAs on p‐type Ge, the formation of n/p junctions occurs when As diffuses into Ge. It is found that this formation begins in the so‐called AsH3 preexposure where Ge substrate is first exposed to AsH3. Also important is the fact that both free carrier profiles and As profiles indicate that prolonged AsH3 preexposure times lead to deeper diffusion depths for the same process time. This effect is concomitant with the degradation of the Ge surface morphology, characterized by higher roughness as the AsH3 preexposure duration is extended. Unlike ion‐implanted As in Ge, which shows a quadratic dependent diffusivity, this MOVPE investigation using AsH3 indicates a linear relationship, consistent with Takenaka et al.’s MOVPE study using TBAs. The analysis of As profiles alongside simulations, with and without subsequent GaAs epitaxy, suggests the generation of Ge vacancies during the process, contributing to deeper As diffusion.

Introduction and aims: Posttransplantation diabetes mellitus (PTDM) is a serious long-term complication that has a negative impact on graft and patient survival. The purpose of the present study was to describe the incidence of PTDM in a Mexican cohort and evaluate its association with a previous family history of diabetes (FHD). Methods: A retrospective single-center cohort study was conducted on patients undergoing liver transplantation (LT). The primary outcome was time from LT to PTDM. The diagnosis of PTDM was established using the ADA criteria. A mediation analysis that used adjusted Cox regression models and considered pretransplant prediabetes a mediator was performed, to determine the total effect and direct effect of FHD on PTDM. Results: A total of 152 patients were included, with a median follow-up time of 41 months; 19.2% (n = 29) had pretransplant diabetes. During the follow-up time, 15% of patients developed PTDM (n = 23), with an incidence rate of 4.71 cases/100 person-years. PTDM was significantly higher in patients with FHD, compared with those with no FHD (8.72 cases/100 person-years vs 2.04 cases/100 person-years, respectively; p = 0.001). The adjusted hazard ratio of PTDM for FHD was 4.14 (95% CI 1.60–10.7), p = 0.005) and 3.48 (95% CI 1.35–9.01, p = 0.010), when further controlled for pretransplant prediabetes. Conclusion: The occurrence of PTDM was similar to that reported in most international studies. As with type 2 diabetes, family history plays an important role in the development of PTDM, even after accounting for pretransplant prediabetes. Patients with FHD should undergo a stricter metabolic program. Resumen: Introducción y objetivos: La diabetes mellitus posterior a trasplante (DMPT) es una complicación grave de largo plazo que tiene un impacto negativo sobre el injerto y la sobrevida del paciente. El objetivo del presente estudio fue describir la incidencia de la DMPT en una cohorte mexicana y evaluar su asociación con el antecedente familiar de diabetes (AFD). Métodos: Se realizó un estudio de cohorte retrospectivo unicéntrico de pacientes sometidos a trasplante hepático (TH). El desenlace primario fue el tiempo entre el TH y el desarrollo de DMPT. El diagnóstico de DMPT fue establecido utilizando los criterios de la ADA. Se realizó un análisis de mediación que utilizó modelos de regresión de Cox ajustados y se manejó la prediabetes pretrasplante como mediador, para determinar el efecto total y el efecto directo del AFD sobre la DMPT. Resultados: Se incluyó a un total de 152 pacientes, con una mediana de seguimiento de 41 meses; 19.2% (n = 29) presentaron diabetes pretrasplante. Durante el tiempo de seguimiento, 15% de los pacientes desarrollaron DMPT (n = 23), con una tasa de incidencia de 4.71 casos/100 personas-año. La DMPT fue significativamente más elevada en pacientes con AFD en comparación con aquellos sin AFD (8.72 casos/100 personas-año vs 2.04 casos/100 personas-año, respectivamente; p = 0.001). El cociente de riesgo ajustado para el desarrollo de DMPT en los pacientes con AFD fue 4.14 (IC 95% 1.60–10.7; p = 0.005) y 3.49 (IC 95% 1.35–9.01; p = 0.010), cuando se controló por prediabetes pretrasplante. Conclusión: La incidencia de DMPT fue similar a la reportada en la mayoría de los estudios internacionales. Al igual que con la diabetes tipo 2, el AFD juega un papel importante en el desarrollo de la DMPT, incluso después de considerar la prediabetes pretrasplante. Los pacientes con AFD deben someterse a un programa metabólico más estricto.

Resumen: Antecedentes: En España, aunque el Ministerio de Sanidad elabora el informe de posicionamiento terapéutico (IPT) y las condiciones de reembolso de los fármacos, las Comunidades Autónomas (CC. AA.) gestionan los servicios de salud y deciden sobre las condiciones de prescripción en su ámbito territorial. El objetivo del estudio EQUIDAD fue describir los condicionantes para la prescripción de los nuevos fármacos en Dermatología en las CC. AA. y sus posibles diferencias. Material y métodos: Estudio transversal realizado en abril-mayo del 2023. Dos dermatólogos con responsabilidades directivas de cada Comunidad Autónoma (C. A.) informaron sobre los condicionantes autonómicos y locales en la prescripción de los fármacos cuyo IPT para el tratamiento de enfermedades dermatológicas fue publicado en los años 2016-2022. Los datos fueron recogidos mediante un cuestionario online. Resultados: Un total de 33 investigadores de 17 CC. AA. participaron en el estudio. Se observaron inequidades entre CC. AA. para el acceso a los nuevos fármacos. Existieron condicionantes autonómicos adicionales al IPT en psoriasis en el 64,7% de las CC. AA., siendo este porcentaje menor en dermatitis atópica (35,3%) o melanoma (11,8%). El más frecuente fue el requisito de un orden de prescripción previo para el uso del fármaco. En algunas CC. AA. se detectaron además variaciones y condicionantes locales (diferencias entre centros de una misma C. A.). Conclusiones: Existe una multiplicidad de criterios tanto a nivel autonómico como local que añade restricciones adicionales a las establecidas por los IPT y que plantean una situación de inequidad entre los pacientes y los profesionales de las diferentes CC. AA. en el acceso a los nuevos fármacos. Abstract: Background: Although the Spanish Ministry of Health prepares national therapeutic positioning reports (TPRs) and drug reimbursement policies, each of the country's 17 autonomous communities (ACs) is responsible for health care services and prescription requirements in its territory. The aim of the EQUIDAD study was to describe and explore potential differences in prescription requirements for new dermatology drugs across the autonomous communities. Material and methods: Cross-sectional study conducted in April and May, 2023. Two dermatologists with management responsibilities from each autonomous community reported on territorial and more local prescription requirements for drugs covered by national TPRs issued between 2016 and 2022. Results: Thirty-three researchers from 17 autonomous communities participated. The data submitted revealed between-community inequities in access to new drugs. Overall, 64.7% of the regions imposed additional prescription requirements to those mentioned in the TPRs for psoriasis. This percentage was lower for atopic dermatitis (35.3%) and melanoma (11.8%). The most common requirement for accessing a new drug was a previous prescription for another drug. Differences and additional requirements were also detected atthe local level (i.e., differences between hospitals within the same autonomous community). Conclusions: Spain's autonomous communities have multiple regional and local prescription requirements that are not aligned with national TPR recommendations. These differences result in inequitable access to new drugs for both patients and practitioners across Spain.

Ground-based radar precipitation products typically need adjustment with rain gauge accumulations to achieve a reasonable accuracy. This is certainly the case for the pan-European radar precipitation products. The density of (near) real-time rain gauge accumulations from official networks is often relatively low. Crowdsourced rain gauge networks have a much higher density than conventional ones and are a potentially interesting (complementary) source to merge with radar precipitation accumulations. Here, a 1-year personal weather station (PWS) rain gauge dataset of ∼ 5 min accumulations is obtained from the private company Netatmo over the period 1 September 2019–31 August 2020, which is subjected to quality control using neighbouring PWSs and, after aggregating to 1 h accumulations, using unadjusted radar data. The PWS 1 h gauge accumulations are employed to spatially adjust OPERA radar accumulations, covering 78 % of geographical Europe. The performance of the merged dataset is evaluated against daily and disaggregated 1 h gauge accumulations from weather stations in the European Climate Assessment & Dataset (ECA&D). Results are contrasted to those from an unadjusted OPERA-based radar dataset and from EURADCLIM. The severe average underestimation for daily precipitation of ∼ 28 % from the unadjusted radar dataset diminishes to ∼ 3 % for the merged radar–PWS dataset. A station-based spatial verification shows that the relative bias in 1 h precipitation is still quite variable and suggests stronger underestimations for colder climates. A dedicated evaluation with scatter density plots reveals that the performance is indeed less good for lower temperatures, which points to limitations in observing solid precipitation by PWS gauges. The outcome of this study confirms the potential of crowdsourcing to improve radar precipitation products in (near) real time.

AbstractTissue barrier permeability plays a crucial role in determining the selective transport of substances across epithelial tissues, including drugs, cosmetic substances, and chemicals. The ability of these substances to cross through tissue barriers affects their absorption into the bloodstream and ultimately their effectiveness. Therefore, the determination of their permeability on these type of tissue barriers represents a useful tool for pharmaceutical and cosmetic industries as well as for toxicological studies.In this regard, microfluidic devices and organ-on-chip technologies are becoming more important to generate reliable data. We have designed and performed an alternative new stratified epithelia-on-chip model that allows to correlate the Stokes radius and the diffusion of molecules and/or nanoformulations through the in vitro generated barrier and establish a system suitable for the analysis of diffusion through stratified epithelium. Thus, extrapolating from experimental data we can predict the Stokes radius for unknown fluorescent labelled particles within a molecular size range, such as gold nanoparticles.

Resumen: La infección por el virus de la hepatitis C (VHC) es un problema de salud pública a nivel mundial asociado a una gran morbimortalidad. En el caso del trasplante hepático, la demanda de órganos continúa siendo mayor que la oferta. Este problema ha llevado a tomar en consideración el uso de órganos de donadores con VHC positivos en receptores negativos.Gracias al advenimiento de los antivirales de acción directa (AAD), los cuales han mostrado ser altamente efectivos para la curación del virus, ha sido posible procurar y utilizar órganos de donadores con infección por el VHC para ser trasplantados. En este artículo se hace una breve revisión de la evidencia actual del uso de órganos provenientes de pacientes infectados por el VHC. Abstract: Hepatitis C virus (HCV) infection is a worldwide public health problem associated with significant morbidity and mortality. In the context of liver transplantation, the demand for organs continues to exceed the supply, prompting the consideration of using organs from HCV-positive donors in HCV-negative recipients. The introduction of direct-acting antivirals (DAAs), which have demonstrated great efficacy in eradicating the virus, has made transplantation of organs from donors with HCV infection possible. The present article provides a brief review of the current evidence on the use of organs from HCV-infected patients.

In this work, we present the most recent updates in the E-OBS gridded data set for daily mean wind speed over Europe. The data set is provided as an ensemble of 20 equally likely realisations. The main improvements of this data set are the use of forward selection linear regression for the monthly background field, as well as a method to ensure the reliability of the ensemble dispersion. In addition, we make a preliminary study into possible causes of the observed terrestrial wind stilling effect, such as local changes in surface roughness length.

Introduction Long-acting injectable antipsychotics (LAIs) offer advantages for schizophrenic patients compared to oral antipsychotics: less frequent dosing, lower relapse rates, better adherence, and lower healthcare costs. LAIs include paliperidone, aripiprazole, olanzapine, risperidone, and zuclopenthixol. Paliperidone palmitate is the only antipsychotic with two formulations with an administration interval longer than one month (3-monthly and 6-monthly), which could be better for the patient and help ensure treatment continuity, especially in cases of limited access to the health care system. Objectives To assess the satisfaction of patients under treatment with 6-month paliperidone palmitate compared to other long-acting injectable antipsychotics with a higher frequency of administration. Methods We analyzed the satisfaction level of a sample of patients receiving treatment with LAIs at the Mental Health Center of El Escorial. All patients had a diagnosis of schizophrenia or other psychotic disorders (according to DSM-5). Patients who met the inclusion criteria completed the Treatment Satisfaction Questionnaire for Medication (TSQM), a generic questionnaire of treatment satisfaction that measures four dimensions: side effects, treatment efficacy, comfort of use, and overall satisfaction. Other clinical and socio-demographic variables were collected, as well as the type of injectable, dose, and frequency of administration. Results Data from approximately 30 patients will be analyzed and discussed later. Conclusions Less frequent administration of LAIs may result in greater patient satisfaction and be just as beneficial clinically. Treatment satisfaction is positively associated with an improvement in psychotic symptoms and seems to be related to better adherence. Disclosure of Interest None Declared
