Health related quality of life scales in women diagnosed with gynecological and breast cancer: The role of resilience. A systematic review

Objective: Resilience and health-related quality of life are factors to be valued today in all types of patients for their relationship to well-being and health. Any stressful situation can significantly impact quality of life and resilience and there are numerous scales to rate these aspects. The main objective of this review is to describe the most used health-related quality of life and resilience scales in gynecological and breast cancer patients to highlight the limitations. Data sources: A review of literature in Pubmed, MEDLINE, Cochrane Database and Google Scholar was carried out to identify articles on health-related quality of life in oncological patients published in English between 2000 and 2020. Methods of study selection: The review was done following the PRISMA guidelines. Tabulation: A total of 460 papers were identified using MeSH terms but finally, according to the inclusion and exclusion criteria, we evaluated 41. Integration and results: Questionnaires have a good performance to quantify quality of life and resilience in oncological patients in general. However, most publications were not focused on patients with gynecological cancer. Conclusions: Due to the particularities of the group of patients with gynecologic and breast cancer secondary to their treatment significantly affecting several areas and domains, it is necessary to validate specific scales for them in order to offer these patients the correct management of their disease at all levels. The role of resilience, premature and iatrogenic menopause and mutilating surgeries are essential to understand the uniqueness of health-related quality of life in gynecological and breast cancer patients. ©2021 The Author(s)

Library of high and mid-resolution spectra in the CaII H & K, Hα, Hβ, NaI D_1, D_2, and HeI D3 line regions of F, G, K and M field stars

In this work we present spectroscopic observations centered in the spectral lines most widely used as optical indicators of chromospheric activity (Hα, Hβ, CaII H & K, and HeI D_3) in a sample of F, G, K and M chromospherically inactive stars. The spectra have been obtained with the aim of providing a library of high and mid-resolution spectra to be used in the application of the spectral subtraction technique to obtain the active-chromosphere contribution to these lines in chromospherically active single and binary stars. This library can also be used for spectral classification purposes. A digital version with all the spectra is available via ftp and the World Wide Web (WWW) in both ASCII and FITS formats

Magnetic study on biodistribution and biodegradation of oral magnetic nanostructures in the rat gastrointestinal tract

We have undertaken a magnetic study on the oral biodistribution and biodegradation of nude maghemite nanoparticles of 10 nm average size (MNP) and probiotic bacteria, Lactobacillus fermentum, containing thousands of these same nanoparticles (MNP-bacteria). Using AC magnetic susceptibility measurements of the stomach, small intestine, cecum and large intestine obtained after rat sacrifice, and iron content determination by ICP-OES, we have monitored the biodistribution and biodegradation of the maghemite nanoparticles along the gastrointestinal tract, after oral administration of both MNP and MNP-bacteria. The results revealed that the amount of magnetic nanoparticles accumulated in intestines is sensibly higher when MNP-bacteria were administered, in comparison with MNP. This confirms our initial hypothesis that the use of probiotic bacteria is a suitable strategy to assist the magnetic nanoparticles to overcome the stomach medium, and to achieve their accumulation in intestines. This finding opens doors to different applications. Since iron absorption in humans takes place precisely in the intestines, the use of MNP-bacteria as an iron supplement is a definite possibility. We have actually illustrated how the administration of MNP-bacteria to iron-deficient rats corrects the iron levels after two weeks of treatment

Triaxial stellar systems following the r1/n luminosity law: an analytical mass-density expression, gravitational torques and the bulge/disc interplay

We have investigated the structural and dynamical properties of triaxial stellar systems whose surface brightness profiles follow the r1/n luminosity law - extending the analysis by Ciotti, who explored the properties of spherical r1/n systems. A new analytical expression that accurately reproduces the spatial (i.e., deprojected) luminosity density profiles (error less than 0.1 per cent) is presented for detailed modelling of the Sérsic family of luminosity profiles. We evaluate both the symmetric and the non-axisymmetric components of the gravitational potential and force, and compute the torques as a function of position. For a given triaxiality, stellar systems with smaller values of n have a greater non-axisymmetric gravitational field component. We also explore the strength of the non-axisymmetric forces produced by bulges with differing n and triaxiality on systems having a range of bulge-to-disc ratios. The increasing disc-to-bulge ratio with increasing galaxy type (decreasing n) is found to greatly reduce the amplitude of the non-axisymmetric terms, and therefore reduce the possibility that triaxial bulges in late-type systems may be the mechanism or perturbation for non-symmetric structures in the disc. Using seeing-convolved r1/n-bulge plus exponential-disc fits to the K-band data from a sample of 80 nearby disc galaxies, we probe the relations between galaxy type, Sérsic index n and the bulge-to-disc luminosity ratio. These relations are shown to be primarily a consequence of the relation between n and the total bulge luminosity. In the K band, the trend of decreasing bulge-to-disc luminosity ratio along the spiral Hubble sequence is predominantly, though not entirely, a consequence of the change in the total bulge luminosity; the trend between the total disc luminosity and Hubble type is much weake

Efectos renales adversos por inhibidores del check-point (ICP) en pacientes con cáncer. Recomendaciones del grupo de Onconefrología de la Sociedad Española de Nefrología (SEN)

Insuficiència renal aguda; ImmunoteràpiaAcute kidney injury; ImmunotherapyInsuficiencia renal aguda; InmunoterapiaThe most widely used approach in the immunotherapy treatment of cancer is the administration of monoclonal antibodies directed against regulatory molecules of immune control that inhibit the activation of T cells, the so-called check point inhibitors (ICI). ICI nephrotoxicity epidemiology and pathology; its diagnosis with or without kidney biopsy; the type and duration of treatment; the possibility of rechallenging after kidney damage; and its indication in patients with cancer and renal transplantation are certainly controversial. In the absence of definitive studies, this document is intended to specify some recommendations agreed by the group of Onconephrology experts of the Spanish Society of Nephrology in those areas related to ICI nephrotoxicity, in order to help decision-making in daily clinical practice in Onconephrology consultations.El enfoque más utilizado en el tratamiento inmunoterápico del cáncer es la administración de anticuerpos monoclonales dirigidos contra moléculas reguladoras del control inmunitario que inhiben la activación de las células T, los llamados inhibidores del Check-Point (ICP). La epidemiología y patología de la nefrotoxicidad por los ICP; su diagnóstico con o sin biopsia renal; el tipo y la duración del tratamiento; la posibilidad de retratar después del daño renal; y su indicación en pacientes con cáncer y trasplante renal son ciertamente controvertidas. En ausencia de estudios definitivos, este documento está destinado a concretar unas recomendaciones consensuadas por el grupo de expertos de Onconefrología de la S.E.N en aquellas áreas relacionadas con la nefrotoxicidad por los ICP, con la finalidad de ayudar en la toma de decisiones en la práctica clínica diaria de las consultas de Onconefrología

Bacteria-Carried Iron Oxide Nanoparticles for Treatment of Anemia

The efficiency of maghemite nanoparticles for the treatment of anemia was sensibly higher when nanoparticles were incorporated onto the probiotic bacterium Lactobacillus fermentum (MNP-bacteria) than when administrated as uncoated nanoparticles (MNP). Plasma iron and hemoglobin, intestine expression of divalent metal transporter 1 (DMT1) and duodenal Cytochrome b (DcytB), as well as hepatic expression of the hormone hepcidin were fully restored to healthy levels after administration of MNP-bacteria but not of MNP. A magnetic study on biodistribution and biodegradation showed accumulation of maghemite nanoparticles in intestine lumen when MNP-bacteria were administrated. In contrast, MNP barely reached intestine. In vivo MRI studies suggested the internalization of MNP-bacteria into enterocytes, which did not occur with MNP. Transmission electronic microscopy confirmed this internalization. The collective analysis of results point out that L. fermentum is an excellent carrier to overcome the stomach medium and drive maghemite nanoparticles to intestine, where iron absorption occurs. Due the probiotic ability to adhere to the gut wall, MNP-bacteria internalize into the enterocyte, where maghemite nanoparticles are delivered, providing an adequate iron level into enterocyte. This paper advances a new route for effective iron absorption in the treatment of anemia.The efficiency of maghemite nanoparticles for the treatment of anemia was sensibly higher when nanoparticles were incorporated onto the probiotic bacterium Lactobacillus fermentum (MNP-bacteria) than when administrated as uncoated nanoparticles (MNP).

Tabaquismo y trastorno mental grave: conceptualización, abordaje teórico y estudios de intervención.

El hábito tabáquico es un grave problema de salud en los pacientes con trastorno mental grave. Este trabajo realiza una revisión actualizada de sus bases neurofisiológicas y abordaje terapéutico. Existe una vinculación conocida entre neurotransmisión nicotínica y esquizofrenia sin una propuesta de modelo etiológico. El abordaje terapéutico del tabaquismo en enfermos psiquiátricos requiere formación específica y unidades de tabaquismo o servicios de salud mental preparados. La asociación con consumo de sustancias tóxicas, psicofármacos, comorbilidad psiquiátrica y falta de motivación profesional constituyen factores limitantes. La intervención breve aprovecha el contacto sanitario para explorar la presencia de tabaquismo y valorar la predisposición del paciente a dejar de fumar. El tratamiento utiliza terapia sustitutiva con nicotina, antidepresivos, agonistas del receptor nicotínico y/o intervenciones psicosociales. El tratamiento con bupropion es el más efectivo y seguro, mientras la terapia sustitutiva con nicotina y la vareniclina son también útiles. En la práctica clínica la utilización de farmacoterapia y psicoterapia puede ser la opción más razonable

Socioeconomic determinants of sarcopenic obesity and frail obesity in community-dwelling older adults: The Seniors-ENRICA Study

Information on the association between socioeconomic status (SES) throughout life and sarcopenic obesity is scarce, whereas no study has been focused on the association between SES and frail obesity. This analysis estimated the prevalence of sarcopenic obesity and frail obesity, and their associations with SES in older adults. Data were collected in 2012 from 1,765 non-institutionalized individuals aged ≥65 participating in the Seniors-ENRICA study in Spain, by using standardized techniques and equipment. SES throughout life was evaluated with the father's occupation, participant's educational level, former own occupation, and current poor housing condition. Overall, 17.2% of participants had sarcopenic obesity, and 4.0% frail obesity. No association was found between SES and sarcopenic obesity. In contrast, the prevalence of frail obesity was higher in those with lower education, having worked in manual job, and currently having poor housing condition. Having ≥1 social disadvantages throughout life was associated with higher prevalence of frail obesity. The prevalence of this disorder increased by 1.49 (95% CI: 1.21-1.85) times for each social disadvantage added. The OR (95% CI) of frail obesity was 3.13 (1.71-5.7) for those having 3 or 4 vs. 0 or 1 social disadvantages, implying a more complex process beginning early in life.Data collection was funded by the following grants: PI13/0288; PI14/0009; PI16/01460; PI16/01512; and PI16/00609 (State Secretary of R+D and FEDER/FSE).
