Serum metabolomic profiling facilitates the non-invasive identification of metabolic biomarkers associated with the onset and progression of non-smal…
2016
Lung cancer (LC) is responsible for most cancer deaths. One of the main factors contributing to the lethality of this disease is the fact that a large proportion of patients are diagnosed at advanced stages when a clinical intervention is unlikely to succeed. In this study, we evaluated the potential of metabolomics by H-1-NMR to facilitate the identification of accurate and reliable biomarkers to support the early diagnosis and prognosis of non-small cell lung cancer (NSCLC). We found that the metabolic profile of NSCLC patients, compared with healthy individuals, is characterized by statistically significant changes in the concentration of 18 metabolites representing different amino acids…
How can dementia and disability be prevented in older adults: where are we today and where are we going?
2021
Abstract Ageing of the population, together with population growth, has brought along an ample increase in the number of older individuals living with dementia and disabilities. Dementia is the main cause of disability in old age, and promoting healthy brain ageing is considered as a key element in diminishing the burden of age‐related disabilities. The World Health Organization recently launched the first risk reduction guidelines for cognitive impairment and dementia. According to recent estimates, approximately 40% of dementia cases worldwide could be attributable to 12 modifiable risk factors: low education; midlife hypertension and obesity; diabetes, smoking, excessive alcohol use, phy…
The final word on nutritional screening and assessment in older persons
2017
Purpose of review: To provide an updated perspective of how nutritional screening and assessment in older persons should be performed and reasonably implemented in the near future. Recent findings: Although nutritional screening and assessment should be fast and easy procedures, there is increasing evidence that more time should be dedicated to them. This is probably an answer to the claim to a medicine being more preventive than curative. Increasing interest is currently given to healthy aging and nutritional status is more likely to be addressed for its implications on functional status and disability. Important prognostic conditions, such as frailty, sarcopenia, and cachexia, which are c…
A nutrition intervention with a main focus on vegetables and bread consumption among young men in the Norwegian National Guard
2013
Background : Young men are difficult to reach with conventional nutrition information and they have a low intake of vegetables and whole grain cereals. Few intervention studies have focused on improving young men’s consumption of vegetables and whole grains. Objective : A 5-month intervention focusing on a combination of increased availability of healthy foods and nutritional information was developed to stimulate the intake of vegetables and semi-whole grain bread among a group of young men in the Norwegian military. Subjects : A total of 376 recruits in the intervention group and 105 recruits in the control group participated in the entire study. Results: The average daily increase in con…
Effects of ibuprofen and carbamazepine on the ion transport system and fatty acid metabolism of temperature conditioned juveniles of Solea senegalens…
2018
The increasing presence of pharmaceuticals in aquatic environments in the last decades, derived from human and veterinary use, has become an important environmental problem. Previous studies have shown that ibuprofen (IB) and carbamazepine (CBZ) modify physiological and biochemical processes in Senegalese sole (Solea senegalensis) in a temperature-dependent manner. In other vertebrates, there is evidence that both of these pharmaceuticals interfere with the ‘arachidonic acid (AA) cascade’, which is responsible for the biosynthesis of numerous enzymes that are involved in the osmoregulatory process. The present work aims to study the temperature-dependent effects of these two pharmaceuticals…
Adipocytes as a Link Between Gut Microbiota-Derived Flagellin and Hepatocyte Fat Accumulation
2016
While the role of both elevated levels of circulating bacterial cell wall components and adipose tissue in hepatic fat accumulation has been recognized, it has not been considered that the bacterial components-recognizing adipose tissue receptors contribute to the hepatic fat content. In this study we found that the expression of adipose tissue bacterial flagellin (FLG)-recognizing Toll-like receptor (TLR) 5 associated with liver fat content (r = 0.699, p = 0.003) and insulin sensitivity (r = -0.529, p = 0.016) in humans (n = 23). No such associations were found for lipopolysaccharides (LPS)-recognizing TLR4. To study the underlying molecular mechanisms of these associations, human HepG2 he…
Consensus recommendation for a diagnostic guideline for acid sphingomyelinase deficiency
2017
Disclaimer: This diagnostic guideline is intended as an educational resource and represents the opinions of the authors, and is not representative of recommendations or policy of the American College of Medical Genetics and Genomics (ACMG). The information should be considered a consensus based on expert opinion, as more comprehensive levels of evidence were not available in the literature in all cases. Background: Acid sphingomyelinase deficiency (ASMD) is a rare, progressive, and often fatal lysosomal storage disease. The underlying metabolic defect is deficiency of the enzyme acid sphingomyelinase that results in progressive accumulation of sphingomyelin in target tissues. ASMD manifests…
Polyglobulie rare par mutation du gène EGLN1 : à propos d’un cas et revue de la littérature
2020
Resume Introduction Le diagnostic etiologique d’une polyglobulie est souvent simple, l’origine etant le plus souvent acquise. Parfois il faut rechercher des formes rares, hereditaires, l’algorithme decisionnel reposant sur le dosage de l’erythropoietine serique et sur la mesure de la pression en oxygene saturant l’hemoglobine a 50 % (P50). Ces pathologies sont en rapport avec des anomalies du recepteur a l’erythropoietine, des hemoglobines hyperaffines ou a des dysfonctionnements de la voie de regulation du facteur HIF (Hypoxia-Inducible Factor) implique dans la sensibilite renale a l’hypoxie. Observation Nous rapportons le cas d’un patient de 56 ans qui presente une polyglobulie inexplique…
Perfiles de resistencia y factores de riesgo de microorganismos resistentes en bacteriemia de origen abdominal
2017
Resumen Objetivo La presencia de microorganismos resistentes es una causa importante de fallo en el tratamiento antimicrobiano inicial. Los objetivos de este estudio son conocer el perfil de resistencia de los microorganismos causantes de bacteriemia de origen abdominal e identificar si el uso previo de antibioticos y el lugar de adquisicion de la bacteriemia son factores de riesgo para determinar la presencia de microorganismos resistentes. Material y metodo Se diseno un estudio de cohorte retrospectiva de todos los pacientes adultos que presentaron bacteriemia y/o fungemia cuyo foco infeccioso primario fue de origen abdominal ingresados en un hospital universitario durante los anos 2011-2…
