Hypertensive states of pregnancyEstados hipertensivos del embarazo / Estados hipertensivos del embarazo

Hypertensive disorders in pregnancy (HDP) remain a leading cause of pregnancy-related maternal and foetal morbidity and mortality worldwide, including chronic hypertension, gestational hypertension, and pre-eclampsia. Affected women and newborns also have an increased risk of cardiovascular disease later in life, independent of traditional cardiovascular disease risks. Despite these risks, recommendations for optimal diagnosis and treatment have changed little in recent decades, probably due to fear of the foetal repercussions of decreased blood pressure and possible drug toxicity. In this document we review the diagnostic criteria and classification of (HDP), as well as important aspects regarding pathophysiology and early detection that allows early identification of women at risk, with the aim of preventing both immediate and long-term consequences. Prophylactic treatment with aspirin is also reviewed early and a therapeutic approach is carried out that involves close maternal and foetal monitoring, and if necessary, the use of safe drugs in each situation. This review aims to provide an updated vision for the prevention, diagnosis, and treatment of HDP that is useful in our usual clinical practice.(AU)

Los estados hipertensivos del embarazo (EHE) siguen siendo una de las principales causas de morbilidad y mortalidad materna y fetal relacionada con el embarazo en todo el mundo, incluyen la hipertensión crónica, la hipertensión gestacional y la preeclampsia. Las mujeres afectadas y los recién nacidos también tienen un mayor riesgo de sufrir enfermedades cardiovasculares en el futuro, independientemente de los riesgos tradicionales de la enfermedad cardiovascular. A pesar de estos riesgos, las recomendaciones para un diagnóstico y un tratamiento óptimo han cambiado poco en las últimas décadas, probablemente por el miedo a las repercusiones fetales de la disminución de la presión arterial y la posible toxicidad farmacológica. En ese documento revisamos los criterios diagnósticos y la clasificación de los EHE, así como aspectos importantes en cuanto a fisiopatología y la detección temprana que permita la identificación precoz de las mujeres en riesgo, con el objetivo de prevenir tanto las secuelas inmediatas como a largo plazo. También se revisa el tratamiento profiláctico con aspirina de forma precoz y se realiza una aproximación terapéutica que implica una estrecha vigilancia materna y fetal, y si es necesario, el uso de fármacos seguros en cada situación. Esta revisión pretende dar una visión actualizada para la prevención, diagnóstico y tratamiento de los EHE que sea de utilidad en nuestra práctica clínica habitual.(AU)

Emergencia hipertensiva como debut de síndrome de Cushing paraneoplásico / Hypertensive Emergency as the Debut of Paraneoplastic Cushing Syndrome

Presentamos el caso de un paciente con antecedentes de hipertensión arterial vasculorrenal tratada un año antes, que acude a urgencias por emergencia hipertensiva (HTA) y disnea. Descartada primera sospecha de reestenosis de arteria renal con angiografía por tomografía computarizada (angioTC), se completa el estudio confirmándose diagnóstico de cáncer de pulmón mediante prueba de imagen y anatomía patológica. En el estudio de hipertensión se detecta elevación de hormona adrenocorticótropa (ACTH), hipercortisolismo y datos analíticos de hiperaldosteronismo. Con el diagnóstico final de síndrome de Cushing secundario a producción ectópica de ACTH se inicia tratamiento médico, sin llegar a recibir nada más por fallecimiento del paciente a los pocos días.(AU)

We present the case of a patient with a history of renal-vascular hypertension treated with stent one year previously, who attended the emergency room due to hypertensive emergency and dyspnea. Once the first suspicion of renal artery restenosis was ruled out with CT angiography, the study was completed, confirming the diagnosis of lung cancer through imaging and pathological anatomy. In the hormonal study, elevation of ACTH, hypercortisolism and analytical data of hyperaldosteronism were detected. With the final diagnosis of Cushing's syndrome secondary to ectopic production of ACTH, medical treatment was started, without being able to receive anything else due to the death of the patient after a few days.(AU)

Azithromycin and moxifloxacin resistance determinants in Mycoplasma genitalium in Lleida, Spain.

OBJECTIVE: Mycoplasma genitalium (MG) is a microorganism related to sexually transmitted infections. Antibiotic resistance of MG leads to an increase in treatment failure rates and the persistence of the infection. The aim of this study was to describe the most frequent mutations associated with azithromycin and moxifloxacin resistance in our geographical area. METHODS: A prospective study from May 2019 to May 2023 was performed. MG-positive samples were collected. Real-time PCRs (AllplexTM MG-AziR Assay and AllplexTM MG-MoxiR Assay, Seegene) were performed in MG positive samples to detect mutations in 23S rRNA V domain and parC gene. RESULTS: A 37.1% of samples presented resistance determinants to azithromycin and the most common mutation detected was A2059G (57.9%). Resistance to moxifloxacin was studied in 72 azithromycin-resistant samples and 36.1% showed mutations, being G248T the most prevalent (73.1%). CONCLUSIONS: The resistance to different lines of treat ment suggests the need for a targeted therapy and the performing of a test of cure afterwards.

Relationship between inflammation and oxidative stress and its effect on multiple sclerosis / Relación entre inflamación y estrés oxidativo y su efecto sobre la esclerosis múltiple

Introduction: This paper highlights the relationship of inflammation and oxidative stress as damage mechanisms of Multiple Sclerosis (MS), considered an inflammatory and autoimmune disease. Development: The oxidative stress concept has been defined by an imbalance between oxidants and antioxidants in favor of the oxidants. There is necessary to do physiological functions, like the respiration chain, but in certain conditions, the production of reactive species overpassed the antioxidant systems, which could cause tissue damage. On the other hand, it is well established that inflammation is a complex reaction in the vascularized connective tissue in response to diverse stimuli. However, an unregulated prolonged inflammatory process also can induce tissue damage. Conclusion: Both inflammation and oxidative stress are interrelated since one could promote the other, leading to a toxic feedback system, which contributes to the inflammatory and demyelination process in MS.(AU)

Introducción: Este trabajo destaca la relación de la inflamación y el estrés oxidativo como mecanismos de daño de la esclerosis múltiple, considerada enfermedad inflamatoria y autoinmune. Desarrollo: El concepto de estrés oxidativo se ha definido por un desequilibrio entre oxidantes y antioxidantes a favor de los oxidantes. Es necesario para realizar funciones fisiológicas, como la cadena respiratoria, pero en ciertas condiciones la producción de especies reactivas sobrepasaba los sistemas antioxidantes, lo que podría causar daño tisular. Por otro lado, está establecido que la inflamación es una reacción compleja en el tejido conectivo vascularizado en respuesta a diversos estímulos, pero un proceso inflamatorio prolongado no regulado también puede inducir daño tisular. Conclusión: Tanto la inflamación como el estrés oxidativo están interrelacionados entre sí, ya que uno de ellos podría promover al otro, dando lugar a un sistema de retroalimentación tóxico, que contribuye al desarrollo del proceso inflamatorio y desmielinizante en la esclerosis múltiple.(AU)

ACL anatomy: Is there still something to learn? / [Artículo traducido] Anatomía del LAC: ¿queda algo por aprender?

BACKGROUND: The different bony and soft tissue reference points and the micro and macroscopic structures of the knee continue to be the object of focused study and analysis. Upon reviewing the most recent literature, we saw the wide spectrum of studies that seek to define the different anatomical aspects of the anterior cruciate ligament (ACL). PURPOSE: The purpose of this paper is to review the most recent publications on the ACL and its morphology in which its microscopic composition and macroscopic anatomy are addressed. RESULTS: The ACL consists of typeI (90%) and typeIII (10%) collagen matrix. Its length ranges from 27 to 38mm and its width from 10 to 12mm. The ACL cross-section area measures an average of 44mm2, and its shape resembles that of an hourglass or a bow tie. ACL bundles have been defined as anteromedial, intermediate, and posterolateral. Femoral and tibial footprints were seen to present a high degree of variability in shape and size. Furthermore, the blood supply is given by the medial genicular artery and innervation by the tibial nerve branches. Additionally, the ACL functionally prevents anterior translation of the tibia and stabilizes against the internal rotation of the tibia and valgus angulation of the knee. CONCLUSIONS: There is great variability in the anatomy of the ACL as well as its attachment sites. At the same time, the shape and size of its footprint has become a factor in determining individualized ACL reconstruction. The persistence of morphological variability in the aging of the ACL and important aspects of surgical planning and decision making with respect to anatomical risk factors suggest that further studies are called for.

Assessment of seabed litter at Concepción Seamount (Canary island) using a remotely operated towed vehicle.

The seafloor is recognised as a major sink for marine litter. However, studies conducted in this compartment addressing marine litter densities and its interactions with fauna are scarce, mainly due to sampling constraints. In this paper, we assess marine litter density, composition and interactions with marine communities and evaluate its relationship with fishing activities at the "Banco de la Concepción" seamount (Canary Islands, Spain). We took advantage of underwater video records taken with a Remotely Operated Towed Vehicle in the framework of the LIFE IP INTEMARES project. A total of 56 video transects were analysed covering about 9 km with 19 h of video recording. Transects were categorised as high, low, and null fishing effort based on the Vessel Monitoring System (VMS) positional data registered between 2009 and 2017. Litter items were recorded in 70% of the transects with a mean density of 2122 (±2464) items km-2. There were significant differences in litter densities over the three levels of fishing pressure, with a density decrease from stations of high to stations of null fishing pressure. Regarding categories, plastic was by far the most abundant category found (83.1%), mainly consisting of fishing lines, both monofilaments and entangled longlines. The study of the interactions of marine litter with fauna showed that less than 20% of the items presented an interaction with benthic organisms either by causing or not a visible impact. The sponge Asconema setubalense accounted for more than half (57.4%) of all interactions, but only 5% of all A. setubalense specimens showed physical damage.

Electroporación irreversible: ampliando las fronteras de la ablación / Irreversible electroporation: Beyond the limits of tumor ablation

La electroporación irreversible o IRE (irreversible electroporation) es una técnica de ablación tumoral no térmica basada en la aplicación de pulsos eléctricos de alto voltaje entre pares de agujas insertadas alrededor de un tumor. La corriente generada favorece la creación de nanoporos en la membrana plasmática, desencadenando la apoptosis. Por ello, la IRE puede utilizarse de manera segura en localizaciones cercanas a estructuras vasculares delicadas, contraindicadas para el resto de técnicas termoablativas. Actualmente la IRE se emplea con éxito para la ablación de tumores en páncreas, riñón e hígado y, de manera muy extendida, como opción terapéutica focal para el cáncer de próstata. La necesidad de un manejo anestésico específico y la colocación precisa y en paralelo de múltiples agujas implican un alto nivel de complejidad, siendo necesaria una gran experiencia del equipo intervencionista. No obstante, se trata de una técnica muy prometedora con una gran capacidad inmunológica sistémica que puede provocar un efecto a distancia del tumor tratado (efecto abscopal).(AU)

Irreversible electroporation (IRE) is a non-thermal tumor ablation technique. High-voltage electrical pulses are applied between pairs of electrodes inserted around and/or inside a tumor. The generated electric current induces the creation of nanopores in the cell membrane, triggering apoptosis. As a result, IRE can be safely used in areas near delicate vascular structures where other thermal ablation methods are contraindicated. Currently, IRE has demonstrated to be a successful ablation technique for pancreatic, renal, and liver tumors and is widely used as a focal therapeutic option for prostate cancer. The need for specific anesthetic management and accurate parallel placement of multiple electrodes entails a high level of complexity and great expertise from the interventional team is required. Nevertheless, IRE is a very promising technique with a remarkable systemic immunological capability and may impact on distant metastases (abscopal effect).(AU)

High frequency of endoluminal thrombus in patients with ischaemic stroke following AARS-CoV-2 infection.

BACKGROUND: Ischaemic stroke may be a major complication of SARS-CoV-2 infection. Studying and characterising the different aetiological subtypes, clinical characteristics, and functional outcomes may be valuable in guiding patient selection for optimal management and treatment. METHODS: Data were collected retrospectively on consecutive patients with COVID-19 who developed acute focal brain ischaemia (between 1 March and 19 April 2020) at a tertiary university hospital in Madrid (Spain). RESULTS: During the study period, 1594 patients were diagnosed with COVID-19. We found 22 patients with ischaemic stroke (1.38%), 6 of whom did not meet the inclusion criteria. The remaining 16 patients were included in the study (15 cases of ischaemic stroke and one case of transient ischaemic attack). Median baseline National Institutes of Health Stroke Scale score was 9 (interquartile range: 16), and mean (standard deviation) age was 73 years (12.8). Twelve patients (75%) were men. Mean time from COVID-19 symptom onset to stroke onset was 13 days. Large vessel occlusion was identified in 12 patients (75%). We detected elevated levels of D-dimer in 87.5% of patients and C-reactive protein in 81.2%. The main aetiology was atherothrombotic stroke (9 patients, 56.3%), with the predominant subtype being endoluminal thrombus (5 patients, 31.2%), involving the internal carotid artery in 4 cases and the aortic arch in one. The mortality rate in our series was 44% (7 of 16 patients). CONCLUSIONS: In patients with COVID-19, the most frequent stroke aetiology was atherothrombosis, with a high proportion of endoluminal thrombus (31.2% of patients). Our clinical and laboratory data support COVID-19-associated coagulopathy as a relevant pathophysiological mechanism for ischaemic stroke in these patients.

Soaring over open waters: horizontal winds provide lift to soaring migrants in weak thermal conditions.

BACKGROUND: For soaring birds, the ability to benefit from variable airflow dynamics is crucial, especially while crossing natural barriers such as vast water bodies during migration. Soaring birds also take advantage of warm rising air, so-called thermals, that allow birds to ascend passively to higher altitudes with reduced energy costs. Although it is well known that soaring migrants generally benefit from supportive winds and thermals, the potential of uplifts and other weather factors enabling soaring behavior remains unsolved. METHODS: In this study, we GPS-tracked 19 Red Kites, Milvus milvus, from the Central European population that crossed the Adriatic Sea on their autumn migration. Migratory tracks were annotated with weather data (wind support, side wind, temperature difference between air and surface-proxy for thermal uplift, cloud cover, and precipitation) to assess their effect on Red Kites' decisions and soaring performance along their migration across the Adriatic Sea and land. RESULTS: Wind support affected the timing of crossing over the Adriatic Sea. We found that temperature differences and horizontal winds positively affected soaring sea movement by providing lift support in otherwise weak thermals. Furthermore, we found that the soaring patterns of tracked raptors were affected by the strength and direction of prevailing winds. CONCLUSION: Thanks to modern GPS-GSM telemetry devices and available data from online databases, we explored the effect of different weather variables on the occurrence of soaring behavior and soaring patterns of migratory raptors. We revealed how wind affected the soaring pattern and that tracked birds could soar in weak thermals by utilizing horizontal winds, thus reducing energy costs of active flapping flight over vast water bodies.

Randomized clinical trial on the use of IMAGE1 S LIGHT (SPIES) vs. white light in the prevention of recurrence during transurethral resection of bladder tumors: Analysis after 12-month follow-up.

INTRODUCTION: The improved image resolution of IMAGE1 S technology will increase tumor detection, achieve a greater number of complete resections, and would probably have an impact on the reduction of recurrences. AIM: The primary objective was to compare the recurrence rates of IMAGE1 S vs. white light during transurethral resection of the bladder (TUR); the secondary objective was to compare the complication rates according to Clavien-Dindo (CD) at 12 months of follow-up. METHODS: Prospective, randomized 1:1, blinded clinical trial. Recurrence and complication rates according to CD were analyzed using chi-square/U Mann-Whitney tests and recurrence-free survival (RFS) using Kaplan-Meier curves. The European Association of Urology (EAU) 2021 scoring model was used. RESULTS: The analysis included 103 participants; 49 were assigned to the IMAGE1 S group and 54 to the white light group. Recurrence rates were 12.2% and 25.9%, respectively (P = .080). The low and intermediate risk group had a lower recurrence rate with IMAGE1 S (7.7% vs. 30.8%, P = .003) and a higher RFS with IMAGE1 S (85.2% vs. 62.8% Log Rank: 0.021), with a Hazard Ratio of 0.215 (95% CI: 0.046-0.925). No differences were observed in the high and very high-risk groups. Complications were mostly grade I and rates were similar between both groups (IMAGE1 S 20.4% vs. white light 7.4% P = .083). CONCLUSIONS: There were no differences in the recurrence rates between groups. However, the low and intermediate risk group had a lower recurrence rate with IMAGE1 S. In addition, perioperative complication rates were not higher.

Mn-porphyrins in a four-helix bundle participate in photo-induced electron transfer with a bacterial reaction center.

Hybrid complexes incorporating synthetic Mn-porphyrins into an artificial four-helix bundle domain of bacterial reaction centers created a system to investigate new electron transfer pathways. The reactions were initiated by illumination of the bacterial reaction centers, whose primary photochemistry involves electron transfer from the bacteriochlorophyll dimer through a series of electron acceptors to the quinone electron acceptors. Porphyrins with diphenyl, dimesityl, or fluorinated substituents were synthesized containing either Mn or Zn. Electrochemical measurements revealed potentials for Mn(III)/Mn(II) transitions that are ~ 0.4 V higher for the fluorinated Mn-porphyrins than the diphenyl and dimesityl Mn-porphyrins. The synthetic porphyrins were introduced into the proteins by binding to a four-helix bundle domain that was genetically fused to the reaction center. Light excitation of the bacteriochlorophyll dimer of the reaction center resulted in new derivative signals, in the 400 to 450 nm region of light-minus-dark spectra, that are consistent with oxidation of the fluorinated Mn(II) porphyrins and reduction of the diphenyl and dimesityl Mn(III) porphyrins. These features recovered in the dark and were not observed in the Zn(II) porphyrins. The amplitudes of the signals were dependent upon the oxidation/reduction midpoint potentials of the bacteriochlorophyll dimer. These results are interpreted as photo-induced charge-separation processes resulting in redox changes of the Mn-porphyrins, demonstrating the utility of the hybrid artificial reaction center system to establish design guidelines for novel electron transfer reactions.

El 67,6% recibió antituberculostáticos (el 72% mostró mejoría) y el 20,6%, antibióticos convencionales (todos con mejoría radiológica). Conclusión: El diagnóstico de la IPMNT es complejo. Los hallazgos clínicos y radiológicos son inespecíficos y un porcentaje importante de pacientes puede presentar otras infecciones concomitantes.(AU)

Objective: To describe the epidemiology and CT findings for nontuberculous mycobacterial lung infections and outcomes depending on the treatment. Material and methods: We retrospectively studied 131 consecutive patients with positive cultures for nontuberculous mycobacteria between 2005 and 2016. We selected those who met the criteria for nontuberculous mycobacterial lung infection. We analyzed the epidemiologic data; clinical, microbiological, and radiological findings; treatment; and outcome according to treatment. Results: We included 34 patients (mean age, 55 y; 67.6% men); 50% were immunodepressed (58.8% of these were HIV+), 20.6% had COPD, 5.9% had known tumors, 5.9% had cystic fibrosis, and 29.4% had no comorbidities. We found that 20.6% had a history of tuberculosis and 20.6% were also infected with other microorganisms. Mycobacterium avium complex was the most frequently isolated germ (52.9%); 7 (20.6%) were also infected with other organisms. The most common CT findings were nodules (64.7%), tree-in-bud pattern (61.8%), centrilobular nodules (44.1%), consolidations (41.2%), bronchiectasis (35.3%), and cavities (32.4%). We compared findings between men and women and between immunodepressed and immunocompetent patients. Treatment was antituberculosis drugs in 67.6% of patients (72% of whom showed improvement) and conventional antibiotics in 20.6% (all of whom showed radiologic improvement). Conclusion: The diagnosis of nontuberculous mycobacterial lung infections is complex. The clinical and radiologic findings are nonspecific and a significant percentage of pateints can have other, concomitant infections.(AU)

Efectos de la pandemia en una consulta de tabaquismo / Effects of the pandemic on a smoking consultation

Objetivo. Análisis de las diferencias entre pacientes atendidos en la unidad hospitalaria de tabaquismo del H. Doctor Peset de Valencia, antes de la pandemia y con posterioridad, para valorar resultados obtenidos en cuanto a abstinencia tabáquica. Material y método. Estudio retrospectivo observacional analizando las mismas variables en dos periodos temporales: pacientes atendidos por primera vez durante el año previo a la pandemia (enero-diciembre 2019) y entre junio de 2021 y junio de 2022 (postpandemia). Se valoran datos demográficos, comorbilidades, dependencia, tratamiento farmacológico prescrito y éxitos obtenidos. Resultados. Diferencias en el número de pacientes atendidos con una reducción de 645 a 115. Incremento de trastornos psiquiátricos de 16,1% a 30,4%. Entre los tratamientos prescritos hay variación en vareniclina (46% a 13,9%) y en citisina (0 a 27,8%). La tasa de abstinencia a los 12 meses disminuye de 37,6% a 8,7% y el porcentaje de abstinencia entre los que completan el seguimiento pasa de 72% a 15,62%. No hay variación significativa en el resto de las variables estudiadas. Conclusión. El impacto de la pandemia en esta consulta se ha reflejado no solo en el drástico descenso del número de pacientes atendidos, sino también en un notable aumento de la comorbilidad psiquiátrica. Además, preocupa la reducción del porcentaje de pacientes que consiguen deshabituación. (AU)

Objective. Analysis of the differences between patients seen in a hospital smoking cessation unit of the H. Doctor Peset de Valencia before and after the pandemic to evaluate the results obtained regarding smoking abstinence. Material and methods. A retrospective observational study analyzing the same variables in two time periods: patients seen for the first time during the year prior to the pandemic (January-December 2019) and between June 2021 and June 2022 (post-pandemic). Demographic data, comorbidities, dependency, drug treatment prescribed and successes obtained are evaluated. Results. Differences were found in the number of patients seen, with a reduction from 645 to 115 and an increase of psychiatric disorders from 16.1% to 30.45. Among the treatments prescribed, there were variations in varenicline (46% to 13.9%) and in cytisine (0 to 27.8%). Abstinence rate at 12 months decreased from 37.6% to 8.7% and the abstinence percentage among those who completed the follow-up from 72% to 15.62%. There are no significant variations in the rest of the variables studied. Conclusion. The impact of the pandemic in this consultation has not only been reflected in the drastic decrease in the number of patients seen but also on a notable increase in psychiatric comorbidity. In addition, the reduction in the percentage of patients who achieved cessation is of concern. (AU)
