Osteoradionecrosis of the jaws triggered by dental implant placement: a case report
2019
Background The decision-making process about how to rehabilitate edentulous osseous defects in patients with head and neck cancer history can be complex. Even though, endosseous dental implants could be considered to be the first choice for treating these patients, it is highly important to be aware of the complications that might occur. The aim of this report was to describe the clinical features of mandibular fracture after dental implants placement on a cancer irradiated patient and update the available information about this event. Case report The case describes a 70-year-old man, with medical background of radiotherapy in jaw bones to treat a carcinoma in the floor of the mouth and lat…
Glypican-3 and Hep Par-1 are Useful Biomarkers in the Cytologic Assessment of Ascites.
2018
Till date, the utility of cytologic assessment of ascites for the identification of hepatocellular carcinoma (HCC) cells is still debated and the usefulness of immunocytochemistry for glypican-3 (GPC3) and Hep Par-1 in this setting has not been reported. Liquid-based cytology of ascitic fluid of 28 cirrhotic patients was performed and the spots obtained were stained with hematoxylin and eosin, papanicolau, and with GPC3 and Hep Par-1 antibodies. GPC3 and Hep Par-1 antibodies stained positively the atypical cells in the ascites of 2 patients with HCC showing an exophytic growth pattern. The specimens of the patients with nonexophytic HCC, other non-HCC cancers, or cirrhosis stained negativel…
Association between trans fatty acid intake and overweight including obesity in 4 to 5-year-old children from the INMA study
2019
Background: Trans fatty acid (TFA) intake has been positively associated with obesity in adults, although the evidence in children is scarce. There is growing evidence that TFA of industrial or natural origin may have different effects. Objectives: We aimed to explore the association between total, industrial, and natural TFA intake and overweight including obesity in 4 to 5-year-old Spanish children. Methods: We cross-sectionally analyzed data of 1744 children aged 4 to 5 from the INMA study, a prospective mother-child cohort study in Spain. We estimated the intake of total, industrial, and natural TFA in grams per day (g/day) using a validated food frequency questionnaire and expressed it…
Prospective risk of stillbirth and neonatal complications in twin pregnancies: systematic review and meta-analysis
2016
Twin pregnancies are at increased risk of stillbirth. Uncomplicated twin pregnancies are commonly delivered earlier to prevent stillbirth; however, there is a risk of neonatal complications associated with being born prior to 39 weeks’ gestation. The optimal gestational age for delivery in twin pregnancies is unknown and likely varies by chorionicity. The present study aimed to determine the prospective risk of stillbirth in women with uncomplicated monochorionic and dichorionic twin pregnancies, and neonatal mortality risks, when delivered beyond 34 weeks of gestation. Data on twin pregnancies that reported rates of stillbirth were obtained from MEDLINE, EMBASE, and Cochrane Library. Separ…
Microbial Colonization of the Peri-Implant Sulcus and Implant Connection of Implants Restored With Cemented Versus Screw-Retained Superstructures: A …
2016
The aim of this study is to investigate peri-implant and intraconnection microflora of healthy implants restored with cemented and screwed superstructures.Patients with two to three implants restored with cemented or screwed restorations and 5 years of follow-up were recruited. Samples were taken from peri-implant sulci, adjacent teeth, and the inner portion of connections. Prevalence of positive sites and bacterial loads for 10 microorganisms were obtained with quantitative real-time polymerase chain reaction. Implant connection permeability to the studied microorganisms was estimated using a standardized bacterial contamination index. Statistical analysis was performed using a generalized…
Reprint of "EXOSOME LEVELS IN HUMAN BODY FLUIDS: A TUMOR MARKER BY THEMSELVES?"
2017
Despite considerable research efforts, the finding of reliable tumor biomarkers remains challenging and unresolved. In recent years a novel diagnostic biomedical tool with high potential has been identified in extracellular nanovesicles or exosomes. They are released by the majority of the cells and contain detailed molecular information on the cell of origin including tumor hallmarks. Exosomes can be isolated from easy accessible body fluids, and most importantly, they can at once provide with several biomarkers, with different levels of specificity. Recent clinical evidence shows that the levels of exosomes released into body fluids may by themselves represent a predictive/diagnostic of t…
Does Pasteurized Donor Human Milk Efficiently Protect Preterm Infants Against Oxidative Stress?
2019
International audience; Pasteurized donor human milk (DHM) is the preferred alternative for infant nutrition when own mother's milk (OMM) is unavailable. Whether DHM is an efficient means for protecting preterm infants from oxidative stress remains unknown. We quantified a panel of oxidative stress biomarkers in urine samples from preterm infants (≤32 weeks of gestation and a birth weight ≤1500 g) receiving ≥80% of feeding volume as either DHM or OMM. The noninvasive in vivo assessment of oxidative stress showed no statistically significant difference between both groups at the time when full enteral nutrition (150 mL/kg body weight) was achieved and until hospital discharge. In addition, t…
DNA methylation links prenatal smoking exposure to later life health outcomes in offspring
2019
Background Maternal smoking during pregnancy is associated with adverse offspring health outcomes across their life course. We hypothesize that DNA methylation is a potential mediator of this relationship. Methods We examined the association of prenatal maternal smoking with offspring blood DNA methylation in 2821 individuals (age 16 to 48 years) from five prospective birth cohort studies and perform Mendelian randomization and mediation analyses to assess whether methylation markers have causal effects on disease outcomes in the offspring. Results We identify 69 differentially methylated CpGs in 36 genomic regions (P value < 1 × 10−7) associated with exposure to maternal smoking in adolesc…
Wet Chemistry and Peptide Immobilization on Polytetrafluoroethylene for Improved Cell-adhesion
2016
Endowing materials surface with cell-adhesive properties is a common strategy in biomaterial research and tissue engineering. This is particularly interesting for already approved polymers that have a long standing use in medicine because these materials are well characterized and legal issues associated with the introduction of newly synthesized polymers may be avoided. Polytetrafluoroethylene (PTFE) is one of the most frequently employed materials for the manufacturing of vascular grafts but the polymer lacks cell adhesion promoting features. Endothelialization, i.e., complete coverage of the grafts inner surface with a confluent layer of endothelial cells is regarded key to optimal perfo…
Predictive validity of the risk SCORE model in a Mediterranean population with dyslipidemia.
2019
Background and aims: Cholesterol treatment for the primary prevention of cardiovascular disease is based on cardiovascular risk, as assessed by the SCORE (Systematic COronary Risk Evaluation) scale. This study aimed to assess the predictive value and clinical utility of the SCORE scale for preventing cardiovascular events and all-cause mortality in people with dyslipidemia and no lipid-lowering treatment. Methods: Patients with dyslipidemia and no lipid-lowering treatment were included from the ESCARVAL-RISK cohort. Cardiovascular risk was calculated by means of the SCORE scale. All deaths and cardiovascular events were recorded for up to five years of follow-up. We calculated sensitivity, …
