Associations of accumulated persistent organic pollutants in breast adipose tissue with the evolution of breast cancer after surgery.

Chronic exposure to persistent organic pollutants (POPs) is suspected to contribute to the onset of breast cancer, but the impact on the evolution of patients after diagnosis is unclear. We aimed to analyze the contribution of long-term exposure to five POPs to overall mortality, cancer recurrence, metastasis, and development of second primary tumors over a global follow-up of 10 years after surgery in breast cancer patients in a cohort study. Between 2012 and 2014, a total of 112 newly diagnosed breast cancer patients were recruited from a public hospital in Granada, Southern Spain. Historical exposure to POPs was estimated by analyzing their concentrations in breast adipose tissue samples. Sociodemographic data were collected through face-to-face interviews, while data on evolution tumor were retrieved from clinical records. Statistical analyses were performed using Cox regression (overall survival, breast cancer recurrence or metastasis) and binary logistic regression models (joint outcome variable). We also tested for statistical interactions of POPs with age, residence, and prognostic markers. The third vs first tertile of hexachlorobenzene concentrations was associated with a lower risk of all-cause mortality (Hazard Ratio, HR = 0.26; 95 % Confidence Interval, CI = 0.07-0.92) and of the appearance of any of the four events (Odds Ratio = 0.37; 95 % CI = 0.14-1.03). Polychlorinated biphenyl 138 concentrations were significantly and inversely associated with risk of metastasis (HR = 0.65; 95 % CI = 0.44-0.97) and tumor recurrence (HR = 0.69; 95 % CI = 0.49-0.98). Additionally, p,p'-dichlorodiphenyldichloroethylene showed inverse associations with risk of metastasis in women with ER-positive tumors (HR = 0.49; 95 % CI = 0.25-0.93) and in those with a tumor size <2.0 cm (HR = 0.39; 95 % CI = 0.18-0.87). The observed paradoxical inverse associations of POP exposure with breast cancer evolution might be related to either a better prognosis of hormone-dependent tumors, which have an approachable pharmacological target, or an effect of sequestration of circulating POPs by adipose tissue.

Targeted Electromyographic Biofeedback With Endoanal Electrostimulation for Anal Incontinence.

Purpose. Anal incontinence (AI) is a disabling condition with a variable response to conservative physical therapies. We assess the utility of combining electromyographic biofeedback with endoanal electrostimulation targeted to the weakest areas of the pelvic floor using the MAPLe® probe (Multiple Array Probe Leiden Novuqare). Methods. Patients with AI unresponsive to conservative measures were assessed before and after treatment with anorectal manometry (ARM), electromyography (EMG), Wexner Continence Scoring, Visual Analog Scoring (VAS), FIQL and SF-12 quality of life determination. Results. Of 29 patients in the final analysis, there was an improvement in the mean Wexner continence score from 13.59 to 8.03 and a concomitant improvement in the reported VAS from 3.45 to 6.72. Both Wexner continence and VAS scores were maintained during follow-up. Maximum voluntary manometric contraction significantly improved from 91.76 mmHg to 110.33 mmHg with no changes in resting pressure. The EMG values ​​(µV) that significantly improved included the average and peak resistance, the average general voluntary contraction, and the average and peak voluntary contraction for both the external anal sphincter and the puborectalis. In the FIQL, behavior, depression and shame domains improved after treatment and during follow-up with lifestyle improvements detected at 6 and 12 months. Physical and mental components of the SF-12 improved at 6 and 12 months. Conclusions. Targeted electromyographic biofeedback and endoanal electrostimulation using MAPLe® probe in AI patients sustainably improves objective ARM and EMG parameters along with subjective reporting of continence severity, VAS, and quality of life.

Reuse of the digestate obtained from the biomethanization of olive mill solid waste (OMSW) as soil amendment or fertilizer for the cultivation of forage grass (Lolium rigidum var. Wimmera).

The principal by-product from the two-phase olive oil production process is olive mill solid waste (OMSW). It is a highly-pollutant by-product, not only because of its characteristics, but also because of the considerable volume of OMSW which is generated, amounting to 2 to 4 million tons per year in Spain. The anaerobic digestion of this by-product is a well-studied process, and results in the generation of biogas, methane and carbon dioxide mainly of high calorific values (20-25 MJ m-3), and an effluent or digestate. The digestate of this by-product has never been characterized. This study presents an informative view on how the composition of OMSW digestate shows promising implications as a soil amendment or fertilizer due to the quality of the biomass from Lolium rigidum, a useful grass specie for the production of forage. Three OMSW digestate alternative applications or treatments were investigated: the digestate and the solid fraction of the digestate for a nutrient-poor soil amendment and the liquid fraction of the digestate as fertilizer. The results confirm that all the OMSW digestate treatments studied presented suitable characteristics for agricultural use, and showed an optimal Carbon/Nitrogen ratio with adequate values for heavy metals which are below the limits established by the Spanish and European legislation in the absence of pathogens. However, fertirrigation was the treatment that provided Lolium rigidum with the best characteristics, improving its shoot biomass, photosynthetic rate and nutritional content.

Reconfigurable artificial microswimmers with internal feedback.

Self-propelling microparticles are often proposed as synthetic models for biological microswimmers, yet they lack the internally regulated adaptation of their biological counterparts. Conversely, adaptation can be encoded in larger-scale soft-robotic devices but remains elusive to transfer to the colloidal scale. Here, we create responsive microswimmers, powered by electro-hydrodynamic flows, which can adapt their motility via internal reconfiguration. Using sequential capillary assembly, we fabricate deterministic colloidal clusters comprising soft thermo-responsive microgels and light-absorbing particles. Light absorption induces preferential local heating and triggers the volume phase transition of the microgels, leading to an adaptation of the clusters' motility, which is orthogonal to their propulsion scheme. We rationalize this response via the coupling between self-propulsion and variations of particle shape and dielectric properties upon heating. Harnessing such coupling allows for strategies to achieve local dynamical control with simple illumination patterns, revealing exciting opportunities for developing tactic active materials.

Transanal endoscopic surgery with a 3D printed device.

BACKGROUND: The aim of this study was to investigate the effectiveness of devices manufactured with 3D printing for performing transanal endoscopic procedures without pneumorectum. METHODS: Functional devices were designed in the Polytechnic School of Engineering of Gijón from 2016 to 2018 using three-dimensional (3D) solid modelling software (Solid-Works®), that allows customization of the device (diameter and length). The devices were made in acrylonitrile butadiene styrene (ABS) by additive manufacturing using an HP Designjet 3D Printer, with fused deposition modelling (FDM) technology. Tests were carried out on mixed simulators (with viscera) and cadavers with a prototype in the form of an open cylindrical base ellipsoid spindle with two bars. In this paper, we present the information of the first series of patients in which this device has been used to perform a full-thikness endoscopic resection of the rectal wall without pneumorectum. The characteristics of the patients, size, and location of the lesion, the type of anesthesia used, the duration of the procedure, hospital stay, complications, and pathology were analyzed. An endoscopic follow-up was also carried out for at least 2 years. RESULTS: Seven interventions were carried out in six patients. The lesions were located at a mean distance of 5 cm from the anal verge and an average area of 11.8 cm2. Four of the procedures were performed with general anesthesia and 3 with spinal anesthesia. Histopathology examination identified 3 adenomas, 3 pT1 and 1 pT2 adenocarcinomas. All excisions were full thickness. En bloc excision was possible in all cases. In only one case of a benign polyp there was a positive lateral margin. As regards complications, there was one case of postoperative rectal bleeding without the need for transfusions. There were no readmissions and no postoperative mortality. CONCLUSIONS: An innovative device made with a 3D printer can be used successfully in transanal endoscopic resections of the rectal wall, with spinal anaesthesia and avoiding the need for pneumorectum.

Batch mesophilic anaerobic co-digestion of spent goat batch mesophilic anaerobic co-digestion of spent goat straw bedding and goat cheese whey: Comparison with the mono-digestion of the two sole substrates.

Spent livestock bedding is a valuable resource for the production of green energy (methane) in rural areas. Comparison and evaluation of batch anaerobic digestion and co-digestion of different mixtures of goat straw bedding (SGSB) and goat cheese whey were carried out. Biochemical methane potential (BMP) tests of the 100% SGSB, 95% SGSB-5% whey, 90% SGSB-10% whey, 85% SGSB-15% whey and 100% whey were found to be 423 ± 7, 354 ± 9, 371 ± 2, 293 ± 1, 274 ± 2 mL CH4 g-1 VS. Two different kinetic models were evaluated. The logistic model revealed a decrease in the maximum methane production rate (Rm) from 34.7 ± 1.5 to 14.1 ± 0.9 mL CH4 g-1 VS·d-1 when the percentage of whey in the mixture increased from 0 to 15% as a consequence of the increased ammonia released during the co-digestion of increased concentrations of whey. The lowest value for the maximum methane production predicted by the model (P) was found for 100% whey (274 ± 10 mL CH4 g-1 VS). A two-substrate model was applied to describe the evident existence of rapid and slowly degradable material. Regarding the hydrolysis kinetic constants predicted by this model, considerable increases in the rapid biodegradation stage (krapid) were observed when comparing to the values found for the slow (kslow) biodegradation stage in all the cases tested. The increases between both constants rose from 5 to 42% when the percentage of whey increased.

Prognostic implications of Anemia in patients with acute heart failure in emergency departments. ANEM-AHF Study.

INTRODUCTION: The presence of anaemia leads to a worse prognosis in patients with heart failure (HF). There are few data on the impact of anaemia on mortality in patients with acute heart failure (AHF), and the studies available are mainly retrospective, and include hospitalised patients. OBJECTIVE: Evaluate the role of anaemia on 30-day and 1-year mortality in patients with AHF attended in hospital emergency departments (HEDs). METHODS: We performed a multicentre, observational study of prospective cohorts of patients with AHF. The study variables were: Anaemia (haemoglobin < 12g/dL in women and <13g/dL in men), mortality at 30 days and at 1 year, risk factors, comorbidity, functional impairment, basal functional grade for dyspnoea, chronic and acute treatment, clinical and analytical data of the episode, and patient destination. STATISTICAL ANALYSIS: Bivariate analysis and survival analyses using Cox regression. RESULTS: A total of 13 454 patients were included, 7662 (56.9%) of whom had anaemia. Those with anaemia were older, had more comorbidity, a worse functional status and New York Heart Association class, greater renal function impairment, and more hyponatraemia. The mortality was higher in patients with anaemia at 30 days and 1 year: 7.5% vs 10.7% (P < .001) and 21.2% vs 31.4% (P < .001), respectively. The crude and adjusted hazard ratios of anaemia for 30-day mortality were: 1.46 (confidence interval [CI] 95% 1.30-1.64); P < .001 and 1.20 (CI 95% 1.05-1.38); P = .009, respectively, and 1.57 (CI 95% 1.47-1.68) and 1.30 (CI 95% 1.20-1.40) for mortality at 1 year. The weight of anaemia on mortality was different in each follow-up period. CONCLUSIONS: Anaemia is an independent predictor of mortality at 30 days and 1 year in patients with AHF attended in HEDs. It is important to study the aetiology of AHF since adequate treatment would reduce mortality.

Safety and Tolerability of Tolvaptan in an Autosomal Dominant Polycystic Kidney Disease Spanish Cohort: A Real-World Experience.

INTRODUCTION: Autosomal dominant polycystic kidney disease (ADPKD) is the commonest inherited disorder of the kidneys. A vasopressin V2-receptor antagonist (tolvaptan) was recently approved for the treatment of ADPKD. This study aims to analyze the safety and tolerability of tolvaptan for the management of ADPKD patients in a real-world setting. METHODS: We conducted a descriptive retrospective study in ADPKD patients in an outpatient clinic setting in Spain from 2018 to 2019. Descriptive statistical analysis of demographics and clinical data, at baseline and one year after tolvaptan initiation, was assessed. Data are presented as median and interquartile range, and as frequencies for categorical variables. RESULTS: Ten patients with ADPKD were identified. At baseline median age was 49.5 (38.5-63.5) years and 60% were males. During treatment with tolvaptan, no significant aquaresis-related symptoms or hepatotoxicity were described. No serious adverse events, discontinuation, or deaths were reported during the study. CONCLUSION: Tolvaptan was well-tolerated without severe adverse events in patients with ADPKD who showed rapid disease progression criteria. Longer follow-up is required to learn about the long-term effects of this treatment.

Cold-Induced Injury Affecting 27% of TBSA: A Case Report.

Frostbite is a particularly severe form of cold-induced injury that most frequently causes tissular damage in acral parts (hands and feet) and usually involves a small extension of the TBSA. Here, we present a rare case of frostbite affecting a large area (27%), which was successfully treated in a similar way to a thermal burn injury.

Sonda intravaginal. Una causa infrecuente de extravasación de orina por fuera de la sonda / No disponible

La colocación de una sonda en una mujer es una técnica sencilla, sin embargo, en casos de obesidad mórbida, vaginitis atrófica, retracción intravaginal del meatro uretral, cirugías o traumatismos pélvicos previos, inflamación o edema local, vulvitis radical y estenosis del meato uretral, esta maniobra resulta mucho más complicada (1-2). Las mujeres muy añosas suele presentar liquen escleroso y atrófico, consistente en una dermatosis crónica inflamatoria, no infecciosa y causa desconocida que retrae y cierra el introito vaginal produciendo lo que se denomina Craurosis vulvar (CV). La CV y la atrofia vaginal posmenopáusica hace que el meato uretral retroceda significativamente dentro de la vagina, lo que se hace imposible su cateterización bajo visión. En ocasiones, la sonda está correctamente colocada en la uretra, pero la paciente tiene la sonda obstruida y/o presenta contracciones vesicales no inhibidas que causan las contracciones del músculo detrusor como antimuscarínicos y espasmolíticos. Presentamos un caso donde un sondaje inadecuado fue erróneamente interpretado como una extravasación de la orina por fuera de la sonda y que no permite recordar qué maniobras debemos usar para resolver un sondaje difícil en la mujer

The placement of a catheter in women is an easy technique. However, in cases of morbid obesity, atrophic vaginitis, intravaginal retraction of urethra and meatus, surgeries or previous pelvic trauma, inflammation of local oedema, vulvitis and urethral meatal stenosis, this maneuver becomes more difficult than 1-2. Lichen sclerosus is most common in elderly women. The cause is unknown. It is a chronic inflammatory skin condition, non-infectious disease which leads to retraction and closure of the vaginal introitus resulting in what is termed "Klaurosis vulvae" (KV). with KV and postmenopausal vaginal atrophy, the urethral meatus recedes significantly along the vaginal wall making its visualization for catheterization impossible. In some cases, the catheter is correctly sited, but the patient can have an obstruction in the catheter and /or present uninhibited bladder contractions which cause the extravasation of urine. In these cases, it is recommended to use vesical washouts in order to unblock the catheter and/or drugs that inhibit the contractions of the detrusor muscle such as antimuscarinic and spasmolytic. We present a case where an inappropriate catheterization was wrongly interpreted as urinary extravasation. due to this, it is of pivotal importance to remember the type of maneuvers we have to perform in case of difficult catheterization in a woman

Exploring the colloid-to-polymer transition for ultra-low crosslinked microgels from three to two dimensions.

Microgels are solvent-swollen nano- and microparticles that show prevalent colloidal-like behavior despite their polymeric nature. Here we study ultra-low crosslinked poly(N-isopropylacrylamide) microgels (ULC), which can behave like colloids or flexible polymers depending on dimensionality, compression or other external stimuli. Small-angle neutron scattering shows that the structure of the ULC microgels in bulk aqueous solution is characterized by a density profile that decays smoothly from the center to a fuzzy surface. Their phase behavior and rheological properties are those of soft colloids. However, when these microgels are confined at an oil-water interface, their behavior resembles that of flexible macromolecules. Once monolayers of ultra-low crosslinked microgels are compressed, deposited on solid substrate and studied with atomic-force microscopy, a concentration-dependent topography is observed. Depending on the compression, these microgels can behave as flexible polymers, covering the substrate with a uniform film, or as colloidal microgels leading to a monolayer of particles.

Utilización de transporte sanitario urgente por los pacientes con ictus isquémico e impacto en los tiempos de atención / Use of emergency medical transport and impact on time to care in patients with ischaemic stroke

Introducción: Numerosos estudios han establecido que el traslado al hospital de los pacientes con ictus por los servicios de transporte sanitario urgente (TSU) implica demoras menores hasta el diagnóstico y tratamiento. Objetivos: Determinar la frecuencia de uso de TSU por los pacientes con ictus en Bizkaia (España), qué factores se asocian con el mismo y el impacto del medio de transporte en los tiempos de atención. Métodos: Se analizaron los datos de 545 pacientes con ictus isquémico agudo hospitalizados y reclutados consecutivamente. Se obtuvieron datos por entrevista a pacientes o acompañantes y de historia clínica. Se estudiaron variables sobre situación previa, síntomas y gravedad (NIHSS) del ictus, modalidad de traslado y tiempos de atención. Se realizaron análisis univariados y multivariados para identificar factores asociados al uso de TSU y con las demoras. Resultados: El 47,2% de los pacientes llegaron al hospital trasladados por TSU. Una mayor gravedad del ictus, la llegada al hospital en horario nocturno y un peor estado funcional previo resultaron asociados de forma independiente con el TSU. El TSU se asoció a una llegada más precoz al hospital. La demora puerta-imagen fue menor en el grupo TSU, pero la asociación desapareció al ajustar por gravedad. La revascularización fue más frecuente entre los trasladados por TSU. Conclusiones: El TSU se asoció a menor demora prehospitalaria. Es necesario desarrollar programas efectivos de educación sanitaria para incrementar el uso de TSU ante los síntomas del ictus. Debe mejorarse la gestión intrahospitalaria del ictus para reducir los tiempos de atención

Introduction: According to numerous studies, using emergency medical services (EMS) to transport stroke patients to hospitals decreases diagnostic and treatment delays. Objectives: To determine the frequency of use of EMS by stroke patients in Bizkaia (Spain), analyse the factors associated with using EMS, and study the impact of EMS on time to care. Methods: We gathered data from 545 patients hospitalised for acute ischaemic stroke and recruited consecutively. Data were obtained from the patients’ medical histories and interviews with the patients themselves or their companions. We studied the following variables: previous health status, stroke symptoms and severity (NIHSS), type of transport, and time to medical care. Univariate and multivariate analyses were performed to identify factors associated with use of EMS and care delays. Results: Patients transported to hospital by the EMS accounted for 47.2% of the total. Greater stroke severity, arriving at the hospital at night, and poor functional status at baseline were found to be independently associated with use of EMS. Use of EMS was linked to earlier arrival at the hospital. Door-to-imaging times were shorter in the EMS group; however, this association disappeared after adjusting for stroke severity. Revascularisation was more frequent among patients transported by the EMS. Conclusions: EMS transport was associated with shorter prehospital delays. Effective health education programmes should be developed to promote EMS transport for patients with stroke symptoms. In-hospital stroke management should also be improved to reduce time to medical care

[Relationship between level of education and one-year survival after ischaemic stroke]. / Relacion del nivel de estudios con la supervivencia en el primer año tras un ictus isquemico.

INTRODUCTION: The relationship between socioeconomic status and incidence or stroke mortality rates is well established. The evidence of an association between this variable and survival is less conclusive. Level of education is a widely-used measure of socioeconomic status in elderly people. AIM: To assess the relationship between one-year survival after stroke and level of education. PATIENTS AND METHODS: We analysed data on 544 consecutively recruited patients admitted for acute ischaemic stroke in one the public hospitals of Bizkaia (Spain). Data were obtained through interviews with patients or accompanying persons and from medical records. We studied variables concerning previous functional status, stroke severity, cardiovascular risk factors and stroke care provided. Patients were followed up for 12 months and the dates of any deaths were recorded. Univariate and multivariate analyses were carried out to assess the relationship between level of education and survival. RESULTS: A total of 203 (86%) women and 273 (88.6%) men were alive at 12 months. In both sexes, individuals with a lower level of education had poorer previous functional status, more severe strokes and higher mortality rates. In the multivariate analysis, the association between level of education and survival remained significant in the adjusted model in men. CONCLUSIONS: In our setting, there are differences in the survival of patients with ischaemic stroke as a function of level of education. The impact of this factor was greater in men than women.

En el analisis multivariado, el nivel de estudios se mantuvo asociado con la supervivencia en el modelo ajustado para los hombres. Conclusiones. La diversidad de nivel educativo marca diferencias en la supervivencia de los pacientes con ictus isquemico en nuestro entorno. El impacto de este factor fue mayor en los hombres que en las mujeres.

Interfacial tension measurements using a new axisymmetric drop/bubble shape technique.

This paper introduces a new mathematical model that is used to compute either the interfacial tension of quiescent axisymmetric pendant/sessile drops and pendant/captive bubbles. This model consists of the Young-Laplace equation, that describes interface shape, together with suitable boundary conditions that guarantee a prescribed volume of drops/bubbles and a fixed position in the capillary. In order to solve the problem numerically, the Young-Laplace equation is discretized by using numerical differentiation and the numerical solutions are obtained applying the well-know Newton method. The paper contains a validation of the new methodology presented for what theoretical bubble/drops are used. Finally, some numerical results are presented for both drops and bubbles of water as well as several surfactant solutions to demonstrate the applicability, versatility and reproducibility of the proposed methodology.

In this paper, we review the actual evidence about contamination through EP and if firefighters are in risk about prostate and testis cancer. OBJECTIVES: To know the involvement of PPE as an additional source of pollution in fire. To see the association with testicular cancer and prostate cancer. METHODS: Research in PubMed, Toxnet, Scopus and OSH Update, Google scholar and institutional websites; we collect 20 articles (11 and 9 related to exposure testicular cancer and prostate). RESULTS: Polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs), some carcinogens, adhering to the EP. Testicular and prostate cancer had a statistically significant association in studies 4 and 5 respectively that assessed incidence and mortality; this included a meta-analysis. CONCLUSIONS: It seems that there's contamination through PPE, as some substances released as a gas, by dermal contamination or by creation of toxic microenvironment between suit and skin. Different substances released during or after the fire stick to the EP, creating a «toxic microenvironment» between the suit and the skin, promoting systemic absorption. We found statistically significant association to prostate and testicular cancer

Characterization of CD34+ hematopoietic progenitor cells in JAK2V617F and CALR-mutated myeloproliferative neoplasms.

Mutations in JAK2 or CALR are observed in patients with myeloproliferative neoplasms (MPN). To get further insight in the dynamics of the mutant clone, we assessed the mutant allele burden in hematopoietic stem cells (HSCs), hematopoietic progenitor cells (HPCs) and granulocytes from 138 patients [51 polycythemia vera (PV), 58 essential thrombocythemia (ET) and 29 myelofibrosis (MF)]. CALR-mutated ET patients harbored a higher mutant load at progenitor level than JAK2V617F-positive ET (HSCs: 39.9% vs 7.5% p<0.001, HPCs: 32.7% vs 7.7% p<0.001). Moreover, HSCs of CALR-mutated ET patients showed a similar mutational load than patients with CALR-mutated MF (39.9% vs 48.2%, p=0.17). Regarding JAK2V617F MPN, PV and ET patients showed a low mutational burden at progenitor level whereas in the myelofibrotic phase the dominance of the mutated clone was a constant finding. In conclusion, the size of the mutated clone in chronic phase MPN is different according to genotype with CALR-mutated ET showing a pattern similar to that observed in MF.
