    Con la propuesta de que el absentismo es un señal que habla de las dificultades en la familia, este artículo trata de explicar, a través de cuatro casos, las características relacionales familiares y entender así la función que el absentismo cumple en ellas. Para ello se analiza el marco y contextos de actuación y cómo determinan las intervenciones. Consideramos necesario ampliar la mirada para introducir posibilidades que faciliten actuaciones desde el modelo sistémico familiar, analizando los estilos parentales y la estructura familiar, y así favorecer el trabajo sobre las relaciones e interacciones de los miembros de la familia.Working from the idea that school absenteeism is a signal that talks about difficulties in the family, this article seeks to explain, through four cases, family relational characteristics and to understand the role that absenteeism plays. We examine the framework and context of action and how they determine the interventions. We believe it is necessary to broaden a vision to introduce possibilities to facilitate performances based on the family systems model, analyzing parenting styles and family structure, thus facilitating the work on relationships and interactions of family members

    Motivation: Age-related macular degeneration (AMD) is a condition characterized by the acumulation of deposits called drusen between the retinal pigment epitheliun (RPE) and Bruch's membrane. As the disease progresses, occurs the degeneration of RPE and photoreceptors cells (dry AMD) or the infiltration of blood vessels from the choroidal vasculature into the retina (wet AMD). To date AMD has no effective treatment. This condition is the leading cause of blindness among elderly individuals worldwide and the total number of patients is expected to increase to 288 million affected individuals in 2040. Resveratrol has shown to have protective effects in others ophthalmologic disorders as diabetic retinopathy, likely through upregulation of Sirt1. The aim of this work is to test some small molecules derivated from resveratrol to see if there is a protective effect against the progression of AMD. Methods: The compounds were tested in vitro using the RPE cell line ARPE-19. Posible toxic effects were studied using RealTime-Glo™ MT Cell Viability Assay and RealTime-Glo™ Annexin V Apoptosis and Necrosis Assay. The efects in the cell cycle were annalised by flow cytometry. Changes in Sirt1 enzymatic activity were messured using SIRT-Glo™ Assay System and Sirt1 expression has been annalised by inmunofluorescence (IF) and western blot (WB) Results: The compounds did not show significant toxic effects or effects for the cell cycle in the concentration range annalised except resveratrol, that seems to cause cell cycle arrest at S and G2/M phase and cell apoptosis. Sirt1 enzymatic activity and Sirt1 expression in the cells do not seem to be increased in response to resveratrol derivates treatment at high doses compared to vehicle control. Conclusions: Resveratrol derivates seem to be safer and less toxic than resveratrol, at least for in vitro use. Further studies are needed to determinate their possible therapeutic applications

    The aim of this study was to evaluate the effect of strontium ranelate (SrR) on bone mineral density (BMD) and boneturnover markers after 1 year of treatment. Additionally, theeffect of SrR in bisphosphonate-naïve patients (BP-naïve)compared to patients previously treated with bisphosphonates (BP-prior) was analyzed. This retrospective study included482 postmenopausal women treated with SrR (2 g/day) for 1year in ten Argentine centers; 41 patients were excludeddue to insufficient data, while 441 were included. Participants were divided according to previous bisphosphonatetreatment in two groups: BP-naïve (n = 87) and BP-prior (n = 350). Data are expressed as mean ± SEM. After 1 year oftreatment with SrR the bone formation markers total alkaline phosphatase and osteocalcin were increased (p < 0.0001),while the bone resorption marker s-CTX was decreased (p =0.0579). Also increases in BMD at the lumbar spine (LS,3.73%), femoral neck (FN, 2.00%) and total hip (TH, 1.54%) [p < 0.0001] were observed. These increments were significant(p < 0.0001) both among BP-naïve and BP-prior patients. Interestingly, the change in BMD after 1 year of SrR treatmentwas higher in BP-naïve patients: LS: BP-naïve = 4.58 ± 0.62%; BP-prior = 3.45 ± 0.28% (p = 0.078). FN: BP-naïve = 2.79 ±0.56%; BP-prior = 2.13 ± 0.29% (p = 0.161). TH: BP-naïve = 3.01± 0.55%; BP-prior = 1.22 ± 0.27% (p = 0.0006). SrR treatmentincreased BMD and bone formation markers and decreaseda bone resorption marker in the whole group, with betterresponse in BP-naïve patients.Fil: Brun, Lucas Ricardo Martín.

    Psicoexposoma: una perspectiva holística más allá de la salud y la enfermedad

    Get PDF
    Antecedentes: el concepto de exposoma surgió como una estrategia para impulsar el estudio exhaustivo de las exposiciones ambientales a lo largo de la vida del individuo y su impacto en la salud. El desarrollo de dispositivos electrónicos para obtener datos de geolocalización, biológicos o biomarcadores de exposición y los avances en las ciencias “ómicas” y en bioinformática permiten la recopilación y el análisis masivo de datos muy diversos. Objetivo: proponer el término psicoexposoma en línea con el concepto de exposoma generado desde las ciencias ambientales. Método: se llevó a cabo una revisión de la literatura para buscar la inclusión de términos psicológicos asociados al concepto de exposoma. Se discute la justificación de un enfoque de psicoexposición para las ciencias psicológicas. Resultados: los términos psicología, psiquiatría o enfermedades neurológicas son escasos en el enfoque del exposoma. La experiencia en el control de variables ambientales sitúa al psicólogo en un punto de partida ventajoso para realizar estudios de psicoexposoma. Conclusión: la psicología puede aprovechar tanto las ciencias de la exposición como las ciencias “ómicas” para crear un enfoque integrado de psicoexposición que pueda ayudar a descifrar la etiología de los trastornos psicológicos y a promover la salud mental del individuo.Background: The concept of the exposome has emerged as a new strategy for studying all environmental exposures throughout an individual’s life and their impact on human health. Nowadays, electronic devices are available to collect data about an individual’s geolocation, biological function, or exposure biomarkers. The appearance of “omic” sciences and advances in bioinformatics have allowed massive data-gathering and analysis from various scientific fields. Objective: to propose the term Psychoexposome in line with the concept of the exposome from the field of environmental sciences. Method: a literature review of psychological terms associated with the exposome concept was carried out and the rationale and benefits of a psychoexposme approach for psychological sciences is discussed. Results: the terms psychology, psychiatry and neurological diseases are scarce in the exposome approach. A long tradition in psychology of performing epidemiological studies and in the study of multifactorial influences traits places psychologists at an advantageous starting point for conducting psychoexposome studies. Conclusion: psychology may take advantage from both exposome and omic sciences to create an integrated psychoexposome approach that may help in deciphering the etiology of psychological disorders and improving people’s mental health

    The Effectiveness of the Low-Level Laser, Antibiotic and Surgical Therapy in the Treatment of Medication-Related Osteonecrosis of the Jaws: A Case Report

    Get PDF
    Introduction: Bisphosphonates consist of a range of drugs used in the treatment of osteopathy or some osteotropic malignancies. Medication-related osteonecrosis of the jaws (MRONJ) is a serious adverse consequence from their use. Conventional treatment is not always effective, so it is necessary to resort to the use of adjuvant therapies. This study aimed to evaluate the effectiveness of the association of surgery, antibiotic therapy and low-level laser (LLL) therapy as a treatment strategy for MRONJ through the presentation of a clinical case.Case presentation: A 49-year-old patient, female gender, presented for diagnosis and treatment of bone lesions in the maxillae. The patient reported that she had used zoledronate for one year. Five years later there were two painless bone lesions in both sides of maxilla, following extraction of the first upper molars. Clinical, tomographic and histopathologic examination established the diagnosis of MRONJ. The treatment consisted of curettage of necrotic bone, antibiotics and thirteen LLL therapy sessions. The integral mucosal healing was observed after two months of follow-up and no symptoms were detected. The patient was evaluated at six and 12 postoperative months without complications.Conclusion: The combination of surgery, antibiotic therapy and LLL therapy has shown be effective in the treatment of MRONJ

    Levetiracetam is a broad-spectrum antiepileptic drug commonly used in intensive care units (ICUs). The objective of this study is to evaluate the adequacy of levetiracetam dosing in patients with normal or augmented renal clearance (ARC) admitted to the ICU by population modelling and simulation. A multicentre prospective study including twenty-seven critically ill patients with urinary creatinine clearance (CrCl) > 50 mL/min and treated with levetiracetam was developed. Levetiracetam plasma concentrations were best described by a two-compartment model. The parameter estimates and relative standard errors (%) were clearance (CL) 3.5 L/h (9%), central volume of distribution (V1) 20.7 L (18%), intercompartmental clearance 31.9 L/h (22%), and peripheral volume of distribution 33.5 L (13%). Interindividual variability estimates were, for the CL, 32.7% (21%) and, for V1, 56.1% (29%). The CrCl showed significant influence over CL. Simulations showed that the administration of at least 500 mg every 8 h or 1000 mg every 12 h are needed in patients with normal renal function. Higher doses (1500 or 2000 mg, every 8 h) are needed in patients with ARC. Critically ill patients with normal or ARC treated with levetiracetam could be at high risk of being underdosed.This research was funded by Department of Education of the Basque Government, grant number PIBA 2019-57; and by the University of the Basque Country UPV/EHU, grant number GIU20/048.

    Relationship between Prenatal or Postnatal Exposure to Pesticides and Obesity: A Systematic Review

    Get PDF
    In recent years, the worldwide prevalence of overweight and obesity among adults and children has dramatically increased. The conventional model regarding the onset of obesity is based on an imbalance between energy intake and expenditure. However, other possible environmental factors involved, such as the exposure to chemicals like pesticides, cannot be discarded. These compounds could act as endocrine-disrupting chemicals (EDC) that may interfere with hormone activity related to several mechanisms involved in body weight control. The main objective of this study was to systematically review the data provided in the scientific literature for a possible association between prenatal and postnatal exposure to pesticides and obesity in offspring. A total of 25 human and 9 animal studies were analyzed. The prenatal, perinatal, and postnatal exposure to organophosphate, organochlorine, pyrethroid, neonicotinoid, and carbamate, as well as a combined pesticide exposure was reviewed. This systematic review reveals that the effects of pesticide exposure on body weight are mostly inconclusive, finding conflicting results in both humans and experimental animals. The outcomes reviewed are dependent on many factors, including dosage and route of administration, species, sex, and treatment duration. More research is needed to effectively evaluate the impact of the combined effects of different pesticides on human health.This study was supported by grants from the Spanish Government (Ministerio de Economía y Competitividad and Instituto Mixto de Investigación-Escuela Nacional de Sanidad (IMIENS)) and the Fondo Europeo de Desarrollo Regional (MINECO-FEDER) Grant numbers: PSI2017-90806-REDT, PSI2017-83038-P, PSI2017-83893-R, PSI2017-86396-P, PSI2017-86847-C2-2-R MINECO-FEDER, and IMIENS: PIC-IMIENS-2018-003.S

    Get PDF
    Background: The efficacy of currently available anthelminthics against Trichuris trichiura infections is significatively lower than for other soil-transmitted helminths (STH). The combination of ivermectin (IVM) and albendazole (ALB) has shown significant improvements in efficacy.Methods: Safety and efficacy randomized controlled clinical trial comparing 3 experimental regimens against ALB monotherapy for the treatment of T. trichiura infections in northern Honduras. Infected children were randomized to one of the following treatments: (Arm 1) single-dose ALB 400 mg; (Arm 2) single-dose ALB 400 mg/IVM 600 μg/kg; (Arm 3) ALB 400 mg for 3 consecutive days; or (Arm 4) ALB 400 mg/IVM 600 μg/kg for 3 consecutive days. Efficacy was measured through egg reduction rate (ERR) and cure rate (CR), both assessed 14-21 days after treatment using the Kato-Katz method. Safety was evaluated by analyzing the frequency and severity of adverse events.Results: A total of 176 children were randomized to one of the 4 treatment arms, 117 completed treatment and follow-up. The ERR for Arms 1 to 4 were: 47.7%, 96.7%, 72.1% and 100%, respectively; with p-values <0.001 between IVM groups and ALB only arms. The CRs were 4.2%, 88.6%, 33.3% and 100%, respectively. A total of 48 (85.4% mild) AEs were reported in 36 children.Conclusions: The combined use of ALB and high-dose IVM is a highly effective and well tolerated treatment for the treatment of T. trichiura infections offering a significantly improved treatment for the control of this infection.Fil: Matamoros, Gabriela.
