Nutritional interventions as modulators of the disease activity for idiopathic inflammatory myopathies: a scoping review.

Idiopathic inflammatory myopathies (IIMs) are chronic, autoimmune connective tissue diseases associated with significant morbidity and disability. Nutrients can activate the immune system and contribute to chronic low-grade inflammation (LGI). Chronic muscle inflammation leads to imbalanced pro-inflammatory and anti-inflammatory cytokines, causing inadequate nutrition, weight loss and muscle weakness during a negative cycle. Owing to its potential to modulate LGI in various diseases, the Mediterranean diet (Med Diet) has been extensively studied. This scoping review explores the nutritional implications and recommendations of the Med Diet as a treatment for immune-mediated diseases, focusing on the gaps in IIM nutritional interventions. A comprehensive literature search of the MEDLINE and EBSCO databases between September 2018 and December 2022 was performed. We identified that the Med Diet and its specific components, such as omega-3 (nω3) fatty acids, vitamin D and antioxidants, play a role in the dietary treatment of connective tissue-related autoimmune diseases. Nutritional interventions have demonstrated potential for modulating disease activity and warrant further exploration of IIMs through experimental studies. This review introduces a dietary therapeutic approach using the Med Diet and related compounds to regulate chronic inflammatory processes in IIMs. However, further clinical studies are required to evaluate the efficacy of the Med Diet in patients with IIMs. Emphasising a clinical-nutritional approach, this study encourages future research on the anti-inflammatory effects of the Med Diet on IIMs. This review highlights potential insights for managing and treating these conditions using a holistic approach.

Factores de riesgo psicosocial asociados con la diabetes mellitus gestacional: revisión sistemática / Psychosocial risk factors associated with gestational diabetes mellitus: systematic review

La diabetes mellitus gestacional DMG es una enfermedad con consecuencias mortales, incapacitantes y costosas para las personas, las familias, las comunidades y los países. Con el fin de establecer de manera sistemática los factores de riesgo psicosocial asociados con la DMG que deberían ser monitoreados durante y después del embarazo se realizó una revisión sistemática en las bases de datos PubMed/Medline y Cochrane. Se encontraron 1188 artículos y se seleccionaron 41. Algunos temas principales fueron conflictos con prácticas culturales, estigma social, influencia de la etnia/raza, bajo nivel educativo, calidad del sueño, problemas con la lactancia materna, preocupación por la propia salud o la del bebé, baja percepción de riesgo de DMG o de diabetes mellitus tipo 2 en el futuro, estrés, ansiedad y depresión, conocimiento limitado, falta de apoyo de la pareja, de la familia o social y de los profesionales de la salud, bajos niveles de autocuidado/autoeficacia y dificultades con cambios en el estilo de vida. Estos factores deberían monitorearse en las embarazadas durante y después del parto. Los tratamientos deberían considerar el impacto psicológico y el riesgo de desarrollar diabetes mellitus tipo 2 después del parto, y deberían ser incluidos en las guías de práctica clínica. Las poblaciones multiétnicas y los grupos más vulnerables demográficamente y socioeconómicamente son más susceptibles de desarrollar DMG.

Gestational diabetes mellitus (GDM) is a disease with fatal, disabling, and costly consequences for individuals, families, communities and countries. To systematically establish the psychosocial risk factors associated with GDM that should be monitored during and after pregnancy. Systematic review in PubMed/Medline and Cochrane databases. 1188 articles were found and 41 were selected. Some main themes were conflicts with cultural practices, social stigma, ethnicity/race influence, low educational level, sleep quality, breastfeeding problems, concern for ones own health/baby, low perception of the risk of GDM/DM2 in the future, stress, anxiety and depression, limited knowledge, lack of support from the partner/family/social and health professionals, low levels of self-care/self-efficacy and difficulties with changes in the lifestyle. These factors should be monitored in pregnant women during and after delivery. Treatments should consider the psychological impact and the risk of developing DM2 after childbirth and should be included in clinical practice guidelines. Multi-ethnic populations and the most demographically and socioeconomically vulnerable groups are more susceptible to developing GDM.

The Effect of Dietary Patterns on Inflammatory Biomarkers in Adults with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Some evidence supports the fact that chronic low-grade inflammation contributes to the physiopathology of type 2 diabetes mellitus (T2DM), and circulating markers of inflammation (e.g., C-reactive protein (CRP), pro- and anti-inflammatory biomarkers (e.g., adiponectin), and endothelial function markers could indicate an ongoing pathology. Following certain dietary patterns (DPs) may result in favorable changes in inflammatory biomarkers. The overarching aim of this systematic review and meta-analysis is to explore the inflammatory effect of healthy DPs on inflammatory biomarkers in adults with T2DM. A systematic search of the literature was conducted using the electronic databases MEDLINE, SCOPUS, and Cochrane Central Register of Controlled Trials. A total of 10 randomized controlled clinical trials (RCTs) were analyzed. In our linear meta-analysis, the random-effects model was applied to estimate standardized mean differences (SMD) to associate the effect of the interventions. Dietary Approaches to Stop Hypertension (DASH), Diabetes UK healthy eating, Mediterranean Diet (MD), Diabetes Prevention Program (DPP), and the American Heart Association's Therapeutic Lifestyle Changes diet were associated with a significant reduction in CRP (SMD: −0.83, 99% CI −1.49, −0.17, p < 0.001; I2 94%), while plasma levels of adiponectin were significantly higher with the intake of MD, DPP, and Diabetes UK healthy eating (SMD: 0.81, 99% CI 0.06,1.56, p < 0.005; I2 96%), both of which indicate less inflammation. Sensitivity analyses were carried out, and potential publication bias was examined. In conclusion, low- moderate-quality evidence from RCTs suggests that, for the DPs evaluated, there are favorable changes in CRP and adiponectin.

Inelastic scattering of low-energy electrons in liquid water computed from optical-data models of the Bethe surface.

PURPOSE: We provide a short overview of optical-data models for the description of inelastic scattering of low-energy electrons (10-10,000 eV) in liquid water. The effect on the inelastic scattering cross section due to different optical data and extension algorithms is examined with emphasis on some recent developments. MATERIALS AND METHODS: The optical-data method whereby experimental optical data and theoretical extension algorithms are used to describe the dependence of the dielectric response function on energy- and momentum-transfer and obtain the Bethe surface of the material, currently represents the most used method for computing the inelastic scattering of low-energy electrons in condensed media. Two sets of experimental optical data for liquid water obtained from reflectance and inelastic X-ray scattering spectroscopy, respectively, and the extension algorithms of Ritchie, Penn, and Ashley are examined. Recent developments are discussed along with the role of corrections to the random phase approximation (RPA) of electron gas theory. RESULTS: The inelastic scattering cross section in the energy range 200-10,000 eV was found to be rather insensitive (to within 10%) to the choice of optical data or the extension algorithm. In contrast, differences between model calculations increase rapidly below 200 eV with the influence of the extension algorithm being dominant. CONCLUSION: The choice of the extension algorithm used to extrapolate optical data to finite momentum transfer and obtain the Bethe surface is crucial in modelling the inelastic scattering of electrons with energies below 200 eV. A new set of measurements on the dielectric response function of liquid water beyond the optical limit and the development of extension algorithms that will go beyond RPA by considering the effect of (short-range) electron exchange and correlation should be of some priority.

A dielectric response study of the electronic stopping power of liquid water for energetic protons and a new I-value for water.

The electronic stopping power of liquid water for protons over the 50 keV to 10 MeV energy range is studied using an improved dielectric response model which is in good agreement with the best available experimental data. The mean excitation energy (I) of stopping power theory is calculated to be 77.8 eV. Shell corrections are accounted for in a self-consistent manner through analytic dispersion relations for the momentum dependence of the dielectric function. It is shown that widely used dispersion schemes based on the random-phase approximation (RPA) can result in sizeable errors due to the neglect of damping and local field effects that lead to a momentum broadening and shifting of the energy-loss function. Low-energy Born corrections for the Barkas, Bloch and charge-state effects practically cancel out down to 100 keV proton energies. Differences with ICRU Report 49 stopping power values and earlier calculations are found to be at the approximately 20% level in the region of the stopping maximum. The present work overcomes the limitations of the Bethe formula below 1 MeV and improves the accuracy of previous calculations through a more consistent account of the dielectric response properties of liquid water.

Megaliposucción: estudio de 120 casos / Megaliposuction: a study of 120 cases

La lipoaspiración es actualmente el procedimiento cosmético más comúnmente realizado en Cirugía Estética. Este trabajo muestra nuestra experiencia a largo plazo, en la remodelación del contorno corporal mediante lipoaspiración de grandes volúmenes (megalipoaspiración), intentando demostrar que esta técnica puede ser aplicada a pacientes bien seleccionados bajo la dirección multidisciplinaria de profesionales. Un total de 120 pacientes fueron tratados en el Centro Internacional de Medicina Avanzada, (CIMA) de Barcelona, España, durante el período de 1 año, desde Noviembre de 2004 hasta Noviembre de 2005. Se realizó lipoescultura de múltiples zonas, con una cantidad media de volumen aspirado de 7.5 l ( entre 6 y 10 l). Discutimos en este trabajo diversas variables, observando la capacidad para mantener controles hemodinámicos estables, con cambios en los valores de hemoglobina y hematocrito pre y postoperatorios que mostraron que no existe un relación directa ni absoluta entre el volumen de grasa aspirada y las pérdidas predecibles de sangre, sino que resulta determinante la calidad de la grasa aspirada y las áreas tratadas, lo que reduce los riesgos y garantiza la satisfacción de los pacientes tratados (AU)

Lipoaspiration is actually the most frecuent cosmetic procedure in aesthetic surgery . This work shows our long term experience in body contouring with large volume liposuction (megaliposuction), trying to demonstrate that it can be applied to selected and prepared patients under multidisciplinary direction. A total of 120 patients were operated on the CIMA (Centro Internacional de Medicina avanzada, Barcelona, España) during 1 year period, from November 2004 to November 2005. We practised liposculpture of different areas with an average aspirated volume of 7,5 l (between 6 and 10 l).In this work we discuss some results and we observe the capacity to keep stable hemodinamic controls with changes in pre a postoperative values of hemoglobin and hematocrit, showing that there is not direct, nor absolute relation between the predictable volume of aspirated fat and the loss of blood; however is more important the quality of the aspirated fat and the anatomical areas treated, to reduce the risks and to assure patients´ satisfaction (AU)
