Sarcopenia, frailty and their prevention by exercise.
2019
Sarcopenia is a major component of the frailty syndrome, both being considered as strong predictors of morbidity, disability, and death in older people. In this review, we explore the definitions of sarcopenia and frailty and summarize the current knowledge on their relationship with oxidative stress and the possible therapeutic interventions to prevent or treat them, including exercise-based interventions and multimodal strategies. We highlight the relevance of the impairment of the nervous system and of the anabolic response (protein synthesis) in muscle aging leading to frailty and sarcopenia. We also discuss the importance of malnutrition and physical inactivity in these geriatric syndr…
Adherence to a healthy lifestyle and multiple sclerosis: a case–control study from the UK Biobank
2020
Background: Multiple sclerosis (MS) is a common and disabling condition. The importance of healthy lifestyle for this disease is poorly explored. Objective: To test whether adherence to healthier lifestyle patterns is associated with a lower presence of multiple sclerosis (MS). Methods: By using a case–control design, we investigated the combined association of four healthy lifestyle-related factors (no current smoking, healthy diet, exercising regularly, body mass index <30 kg/m2) and the prevalence of MS. A logistic regression analysis, adjusted for potential confounders, was used and data reported as odds ratios (ORs) with their 95% confidence intervals (CIs). Results: 728 participant…
Role of the DNA repair glycosylase OGG1 in the activation of murine splenocytes
2017
OGG1 (8-oxoguanine-DNA glycosylase) is the major DNA repair glycosylase removing the premutagenic DNA base modification 8-oxo-7,8-dihydroguanine (8-oxoG) from the genome of mammalian cells. In addition, there is accumulating evidence that OGG1 and its substrate 8-oxoG might function in the regulation of certain genes, which could account for an attenuated immune response observed in Ogg1-/- mice in several settings. Indications for at least two different mechanisms have been obtained. Thus, OGG1 could either act as an ancillary transcription factor cooperating with the lysine-specific demethylase LSD1 or as an activator of small GTPases. Here, we analysed the activation by lipopolysaccaride…
Oxidatively generated base modifications in DNA: Not only carcinogenic risk factor but also regulatory mark?
2016
The generation of DNA modifications in cells is in most cases accidental and associated with detrimental consequences such as increased mutation rates and an elevated risk of malignant transformation. Accordingly, repair enzymes involved in the removal of the modifications have primarily a protective function. Among the well-established exceptions of this rule are 5-methylcytosine and uracil, which are generated in DNA enzymatically under controlled conditions and fulfill important regulatory functions in DNA as epigenetic marks and in antibody diversification, respectively. More recently, considerable evidence has been obtained that also 8-oxo-7,8-dihydroguanine (8-oxoG), a frequent pro-mu…
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…
Designing food packaging for the Spanish market: Do motivations differ between involved and non-involved adolescents?
2018
Abstract This paper investigates the relationships among food choice motivations and the relevance of packaging elements (visual and informative elements) in the adolescent market. In addition, these relationships are re-tested in two different frameworks: high-involved consumers and low-involved consumers. 590 young consumers between 13 and 17 years were interviewed at the door of their public or private schools. Structural Modelling was used to test our hypotheses. The first analysis was done considering the global sample. The second one split off the sample into two groups: 351 high-involved adolescents and 239 low-involved adolescents. Our results showed, on one side, that weight contro…
The impact of physical activity on psychological health during Covid-19 pandemic in Italy
2020
The worldwide spread of COVID-19 has upset the normality of Italian daily life, forcing population to social distancing and self-isolation. Since the containment precautions also concern sport-related activities, home workout remained the only possibility to play sports and stay active during the pandemic. The present study aimed to examine changes in the physical activity levels during self-quarantine in Italy, and the impact of exercise on psychological health. A total of 2974 Italian subjects has completed an online survey, but only 2524 subjects resulted eligible for this study. The questionnaire measured the total weekly physical activity energy expenditure before and during quarantine…
Epigenetic IVD Tests for Personalized Precision Medicine in Cancer
2019
Epigenetic alterations play a key role in the initiation and progression of cancer. Therefore, it is possible to use epigenetic marks as biomarkers for predictive and precision medicine in cancer. Precision medicine is poised to impact clinical practice, patients, and healthcare systems. The objective of this review is to provide an overview of the epigenetic testing landscape in cancer by examining commercially available epigenetic-based in vitro diagnostic tests for colon, breast, cervical, glioblastoma, lung cancers, and for cancers of unknown origin. We compile current commercial epigenetic tests based on epigenetic biomarkers (i.e., DNA methylation, miRNAs, and histones) that can actua…
Endoscopic near infrared and indocyanine green to verify the viability of the subcutaneous flap for vulvar cancer.
2019
Abstract Introduction Vulvar cancer often requires radical vulvectomy with subsequent vulvar flap. Approximately in 20–60% of cases, there are post-operative complications ranging from infection to flap necrosis that often require reoperation. Several methods have been described to verify the vitality of the flap, but these are often expensive and require specific machinery that is not generally present in a gynecological clinic. In this case report, we present a viability verification of V Y fasciocutaneous advancement flap for vulvar reconstruction by Endoscopic Near-Infrared and Indocyanine Green. Methodology The patient was a 67-year-old woman with FIGO IB ≤ 4 cm squamous cell vulvar ca…
Sperm chromosomal abnormalities and their contribution to human embryo aneuploidy.
2018
In this work we reviewed 18 years of experience using fluorescence in situ hybridization (FISH) for sperm aneuploidy testing. We evaluated parameters associated with increased numerical sperm chromosome abnormalities and determined the male contribution to embryo aneploidies in terms of reproductive outcome by increased sperm aneuploidy. This retrospective study analyzed data from 2008 sperm samples of infertile males undergoing FISH analysis because of clinical history of repetitive implantation failure, recurrent miscarriage, impaired sperm parameters, or mixed causes. Sperm concentration was the only sperm parameter associated with FISH results—we observed a gradual increase of abnormal …
