Psychological flexibility mediates change in intuitive eating regulation in acceptance and commitment therapy interventions
2017
AbstractObjectiveDespite the promising results related to intuitive eating, few studies have attempted to explain the processes encouraging this adaptive eating behaviour. The focus of the present study was on exploring mechanisms of change in intuitive eating and weight in acceptance and commitment therapy (ACT) interventions. Mediation provides important information regarding the treatment processes and theoretical models related to specific treatment approaches. The study investigates whether psychological flexibility, mindfulness skills and sense of coherence mediated the interventions’ effect on intuitive eating and weight.DesignSecondary analysis of a randomized control trial. Mediati…
Prospective randomised trial of two dose levels of megestrol acetate in the management of anorexia-cachexia syndrome in patients with metastatic canc…
1996
Two doses of megestrol acetate (MA) have been prospectively compared in a random fashion as treatment for cancer-related anorexia-cachexia syndrome (ACS) in 122 patients with progressive soft tissue sarcoma, colorectal, lung, head and neck and renal cancer resistant to systemic chemotherapy. After 30 days of MA, 55% of patients receiving MA at 160 mg day-1 reported an increase in appetite, 27% of patients no variation and 18% complained of a decrease in appetite. Patients treated with MA at 320 mg day-1 reported an increase in appetite in 68% of cases, a stabilisation in 20% of cases and a decrease in 12%. Although an increase in appetite was more frequently observed in patients receiving M…
La alimentación como fuente de conflicto entre paciente y familia en cuidados paliativos
2020
Resumen Introducción: los conflictos forman parte de las relaciones humanas. Pocos estudios han contemplado los conflictos que la alimentación puede producir en la fase final de la vida, los factores que inciden en su aparición y la forma de gestionarlos. Su conocimiento ayudaría al equipo asistencial a mejorar el cuidado de estos pacientes y sus familias. Objetivo: analizar la existencia del conflicto intrafamiliar vinculado con la alimentación en la enfermedad oncológica en cuidados paliativos, la gestión del mismo y la influencia en su aparición de los cambios en la alimentación, el control sobre la misma, la necesidad de comer, el acompañamiento, la adaptación a la enfermedad y la vincu…
Importance of mitochondrial dynamin-related protein 1 in hypothalamic glucose sensitivity in rats.
2012
International audience; AIMS: Hypothalamic mitochondrial reactive oxygen species (mROS)-mediated signaling has been recently shown to be involved in the regulation of energy homeostasis. However, the upstream signals that control this mechanism have not yet been determined. Here, we hypothesize that glucose-induced mitochondrial fission plays a significant role in mROS-dependent hypothalamic glucose sensing. RESULTS: Glucose-triggered translocation of the fission protein dynamin-related protein 1 (DRP1) to mitochondria was first investigated in vivo in hypothalamus. Thus, we show that intracarotid glucose injection induces the recruitment of DRP1 to VMH mitochondria in vivo. Then, expressio…
Anorexia and Eating Patterns in the Elderly
2013
Objectives To evaluate the change in eating habits occurring in community- dwelling and institutionalized elderly subjects with senile anorexia. Design Cross- sectional, observational. Setting Community, nursing homes and rehabilitation or acute care facilities in four Italian regions. Participants A random sample of 526 subjects, aged 65 years and older (217 free living individuals, 213 residents in nursing homes, and 93 patients in rehabilitation and acute wards). Measurements All subjects underwent a multidimensional geriatric evaluation of: nutritional status, anthropometric parameters, health and cognitive status, depression, taste, chewing and swallowing function, and some hormones re…
Health-related quality of life is a prognostic factor for survival in older patients after colorectal cancer diagnosis: A population-based study
2015
International audience; Background: Studies carried out in the context of clinical trials have shown a relationship between survival and health-related quality of life in colorectal cancer patients.Aims: We assessed the prognostic value of health-related quality of life at diagnosis and of its longitudinal evolution on survival in older colorectal cancer patients. Methods: All patients aged >= 65 years, diagnosed with new colorectal cancer between 2003 and 2005 and registered in the Digestive Cancer Registry of Burgundy were eligible. Patients were asked to complete the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at inclusion, three, six …
The role of attentional biases to appetitive stimuli in childhood overweight
2018
Overweight during childhood constitutes a high-risk factor for adult obesity. An abnormal attention to food stimuli (i.e., a bias) has been suggested as an underlying mechanism to the onset and/or maintenance of obesity. Previous literature supports the existence of a biased attention toward food stimuli in adults with obesity. However, it is unknown whether this attentional bias occurs in high-risk children for adult obesity. We aimed to examine attentional biases to food at different stages of attention processing in overweight children. A dot-probe task was applied to 25 children with overweight and 25 healthy-weight children (8-12 years old). Attentional preference to or avoidance of pl…
Physiological and oral parameters contribute prediction of retronasal aroma release in an elderly cohort.
2021
International audience; Malnutrition is a serious problem in the elderly while understanding flavour perception could be a tool for controlling appetite or food choices. To increase our knowledge, we characterised the health and oral physiology (oral volume, swallowing tongue force, number of teeth and salivary flow rate, protein content and antioxidant capacity) of a cohort of 54 community-dwelling French elderly as well as their individual retronasal release of five aroma compounds (2-pentanone, 2-nonanone, 2,3-hexanedione, octanal and linalool) by proton-transfer-reaction mass spectrometry (PTR-MS). In general, large variability across participants was observed in both oral physiological…
Opioid-induced or pain relief-reduced symptoms in advanced cancer patients?
2006
Abstract Background While opioids in increasing doses may produce adverse effects, the same adverse effects may be associated with poor pain control. Moreover, in the clinical setting symptomatic treatment and illness may balance the outcome of opioid titration. Some adverse effects may tend to disappear continuing the treatment in a long-term period. Aims The aim of this study was to monitor the effects of a rapid opioid titration combined with symptomatic treatment in patients with poor relief and to monitor these changes in the following period of 20 days. Methods A consecutive sample of 35 patients admitted to an acute Pain Relief and Palliative Care Unit were titrated with opioids, acc…
Alterations in the Hippocampal Endocannabinoid System in Diet-Induced Obese Mice
2010
The endocannabinoid (eCB) system plays central roles in the regulation of food intake and energy expenditure. Its alteration in activity contributes to the development and maintenance of obesity. Stimulation of the cannabinoid receptor type 1 (CB1receptor) increases feeding, enhances reward aspects of eating, and promotes lipogenesis, whereas its blockade decreases appetite, sustains weight loss, increases insulin sensitivity, and alleviates dysregulation of lipid metabolism. The hypothesis has been put forward that the eCB system is overactive in obesity. Hippocampal circuits are not directly involved in the neuronal control of food intake and appetite, but they play important roles in hed…
