Orexin system: Network multi-tasking
2018
Orexin system regulates sleep/wake states and its deficiency result in narcolepsy thus indicating the crucial role of orexins in maintaining wakefulness. There are two types of orexin peptides: the orexin-A (OXA or hypocretin 1) and orexin-B (OXB or hypocre- tin 2). The Majority of the central nervous system orexin peptides are synthesized in neurons located in the lateral and back hypotha- lamus and send projections throughout the brain regions Orexin neurons are “multi-tasking” hence regulating also energy homeosta- sis, reward systems and feeding behaviour through connection with hypothalamic nuclei and through responsiveness to leptine and glucose. It has recently been found a connectio…
Malestar psicológico y apoyo psicosocial en víctimas de ciberbullying
2018
El ciberbullying es un problema creciente que suscita mucha preocupación social. Los estudios sugieren que el ciberbullying conlleva graves consecuencias para el bienestar psicológico de las cibervíctimas, y que éstas se encuentran solas ante la intimidación. En este contexto, el objetivo del presente trabajo fue analizar las consecuencias del ciberbullying en cuanto a la cibervictimización, el malestar psicológico, el apoyo emocional percibido y la soledad en las cibervíctimas en función de la duración de este tipo de intimidación (no me ha pasado, 1 mes (o menos), entre 3 y 6 meses, o 1 año (o más)). La muestra estuvo compuesta por 1023 adolescentes (51.2% chicos y 48.8% chicas), entre 12…
Striving to maintain a dignified life for the patient in transition: Next of kin’s experiences during the transition process of an older person in tr…
2015
Next of kin represent significant resources in the care for older patients. The aim of this study was to describe and illuminate the meaning of the next of kin’s experiences during the transition of an older person with continuing care needs from hospital to home. The study has a phenomenological hermeneutic design. Individual, narrative interviews were conducted, and the data analysis was conducted in accordance with Lindseth and Norberg’s phenomenological hermeneutic method. Two themes and four subthemes were identified and formulated. The first theme: “Balancing vulnerability and strength,” encompassed the subthemes “enduring emotional stress” and “striving to maintain security and conti…
Group analytic therapy for eating disorders: preliminary results in a single-group study.
2008
Objectives There is a lack of empirical data on the effectiveness and process of group-analytic therapy in eating disorders. This single-group study aimed to explore the effectiveness of such treatment for anorexic and bulimic individuals. Method Eight patients (three anorexic and five bulimic women) entered group-analytic treatment, meeting weekly for 2 years. Eating behaviours, overall psychological distress and group process variables were regularly assessed using quantitative and qualitative measures, with comparisons made at the beginning and end of the therapy. Results Treatment was discontinued in two cases. When outcome was classified on the basis of reliable change and clinical sig…

Resultados: Se encontraron niveles de exposicion a influencia en el trabajo inferiores al punto medio de la escala (50, escala de 0 a …
Harsh times: do stressors lead to labor market losses?
2018
This paper examines the links between stressful life events and labor market outcomes. We use twin data for Finnish men and women combined with register-based individual information on earnings, employment and social income transfers. The twin data allow us to account for shared environmental and genetic confounders. We measure the exposure to stressful life events in 1990. The labor market outcomes are measured during a 20-year follow-up over the period 1990–2009. Three findings stand out. First, stressors lead to worse labor market outcomes. Second, both men and women are distressed by labor market shocks, but they respond differently to marital problems and health shocks within the famil…
Job insecurity and sickness absence: Correlations between attrition and absence in 36 occupational groups
2012
Aims: To investigate how job insecurity, as indicated by attrition rates out of employment, affects sickness absence among remaining workers. Methods: A longitudinal analysis investigated how the percentage of workers absent due to sickness was affected by attrition out of employment in Norwegian Labour Force Surveys from 1997 to 2005, between 31 quarterly observations at the level of 36 occupational groups. Results: Rising attrition is associated with more sickness absence. Conclusions: Previous research has argued that job insecurity can lead to more absence because of a stressor effect as well as to less absence because of a disciplinary effect. This research indicates that the stressor…
Work incapacity among family caregivers : a record linkage study
2022
BackgroundFamily caregiving-related physical and mental health problems may lead to work incapacity in employed caregivers. The aim of this study was to quantify sickness absences and disability pensions (SADP) among high-intensity family caregivers available to the labour market compared with a control population.MethodsThe study sample included all individuals in Finland, who had received caregiver’s allowance and were available to the labour market in 2012 (n=16 982) and their controls (n=35 371). Information on the number of sickness absence (spells >10 days) and disability pension (SADP) days and related diagnoses according to ICD-10 were obtained from national registers for the yea…
Metformin induces lipid changes on sphingolipid species and oxidized lipids in polycystic ovary syndrome women.
2019
Metformin is one of the treatments used for pcoS pathology decreasing body weight, plasma androgen, FSH and glucose levels. Unfortunately, there is little known about metformin’s effects on lipid metabolism, a crucial process in pcoS pathology. We have employed a lipidomic approach to explore alterations in the plasma lipid profile of patients with PCOS following metformin treatment. The aim is to offer new insights about the effect of metformin in PCOS patients. Plasma samples were obtained from 27 subjects prior to and following 12 weeks of metformin treatment. A detailed biochemical characterization and lipidomic profile was performed. Metformin reduces BMI, HOMA-IR, fSH and androstenedi…
Experimental Study of the Effects of EIPA, Losartan, and BQ-123 on Electrophysiological Changes Induced by Myocardial Stretch
2015
[ES] Introducción y objetivos Se han implicado diversos mecanismos en la respuesta mecánica al estiramiento miocárdico, que incluyen la activación del intercambiador Na+/H+ por acciones autocrinas y paracrinas. Se estudia la participación de estos mecanismos en las respuestas electrofisiológicas al estiramiento agudo miocárdico mediante el análisis de los cambios inducidos con fármacos. Métodos Se analizan las modificaciones de la fibrilación ventricular inducidas por el estiramiento agudo miocárdico en corazones de conejo aislados y perfundidos utilizando electrodos múltiples epicárdicos y técnicas cartográficas. Se estudian 4 series: control (n = 9); durante la perfusión del antagonista d…
