Prenatal Exposure to Organochlorine Compounds and Birth Size
2011
Objective: To investigate the possible association between birth size and cord concentrations of some organochlorine compounds (OCs), including 4,4′-dichlorodiphenyltrichloroethane (DDT), 4,4′-1,1-dichloro-2,2-bis(p-dichlorodiphenyl)ethylene (DDE), hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), 4 polychlorinated biphenyl (PCB) congeners (118, 138, 153, and 180), and their sum (ΣPCBs) in a birth cohort in Valencia, Spain. Study Design: A total of 494 mothers and their newborns (born 2003–2006) participated in the study. Multivariate linear regression analyses were performed between birth weight, length, or head circumference and OC concentrations. Results: Median concentrations of…
Combined strength and endurance session order: differences in force production and oxygen uptake.
2015
Purpose:To examine acute responses of force production and oxygen uptake to combined strength (S) and endurance-running (E) loading sessions in which the order of exercises is reversed (ES vs SE).Methods:This crossover study design included recreationally endurance-trained men and women (age 21−45 y; n = 12 men, 10 women) who performed ES and SE loadings. Force production of the lower extremities including countermovement-jump height (CMJ) and maximal isometric strength (MVC) was measured pre-, mid-, and post-ES and -SE, and ground-reaction forces, ground-reaction times, and running economy were measured during E.Results:A significant decrease in CMJ was observed after combined ES and SE in…
Norepinephrine transporter gene polymorphism is not associated with susceptibility to alcohol dependence
2002
Abnormalities in monoamine neurotransmission have been implicated in the pathogenesis of alcoholism, mood disorders and schizophrenia. Murine norepinephrine transporter gene (NET) has been mapped to a region on chromosome 8 where a quantitative trait locus for ethanol sensitivity. Therefore we tested whether norepinephrine transporter (NET) gene variants confer susceptibility to either alcohol dependence or severe alcohol withdrawal symptoms. There is a highly polymorphic silent G1287A mutation in the NET gene. In our study 157 alcoholics and 185 healthy unrelated matched control subjects were analyzed for a silent G1287A mutation. No significant differences in allele and genotype distribut…
Polymorphisms in the N-methyl-D-aspartate receptor 1 and 2B subunits are associated with alcoholism-related traits.
2003
Abstract Background This study examined the hypothesis that allelic variants of the ionotropic glutamatergic N-methyl-D-aspartate receptor (NMDAR) are associated with vulnerability to alcoholism and some related traits. Methods We investigated the silent G2108A and C2664T polymorphisms of the NMDAR1 and the NMDAR2B genes, respectively. The case control study included 367 alcoholic and 335 control subjects of German origin. The family-based study comprised 81 Polish alcoholic patients and their parents using the transmission disequilibrium test. Results The genotype frequencies of the NMDAR1 polymorphism differed significantly between control and alcoholic subjects. This difference was also …
Prognostic significance of repetitive ventricular response in chronic coronary artery disease.
1985
A prospective study was conducted in 267 patients with angiographically defined coronary artery disease without documented ventricular tachycardia to determine the prognostic significance of repetitive ventricular response (RVR) after programmed electrical stimulation (PES). The patients were classified inducible if RVR with 3 or more echo beats (RVR greater than or equal to 3) could be induced. 89 patients without previous myocardial infarction (MI), 61 survivors of MI occurring between 6 weeks and 3 months before and 117 patients who had survived longer than 3 months after MI were studied. A standardized stimulation protocol with single (S1S2) and double (S1S2S3) extrastimuli during ventr…
Neural activation after maximal isometric contractions at different muscle lengths.
2006
DESBROSSES K., N. BABAULT, G. SCAGLIONI, J.-P. MEYER, and M. POUSSON. Neural Activation after Maximal Isometric Contractions at Different Muscle Lengths. Med. Sci. Sports Exerc., Vol. 38, No. 5, pp. 937–944, 2006. Purpose: To investigate i) whether neural activation dependence on muscle length is preserved with neuromuscular fatigue and ii) whether fatigue induced by a maximal isometric exercise is muscle length dependent. Methods: Twelve male subjects performed two fatiguing quadriceps muscle exercises: FS is the fatigue carried out at short muscle length (S) (S = 40- of knee flexion) and FL is the fatigue at long muscle length (L) (L = 100-). Before and after each fatiguing exercise (i.e.…
Intraperitoneal Onlay Mesh Technique for Spigelian Hernia in an Outpatient and Short-Stay Surgery Unit: What's New in Intraperitoneal Meshes?
2018
Spigelian hernia (SH) is a rare entity, but its surgical treatment is essential because of its high complication risk. Laparoscopic approaches have become the option in elective surgery because it has less morbidity and requires a shorter stay. Several laparoscopic techniques have been employed, but there is no gold standard technique for this kind of hernia. We report, in this study, our experience with intraperitoneal onlay mesh (IPOM) repair.Fifteen patients underwent elective surgery for SH between 2008 and 2015 in a Short-Stay Surgical Unit. Laparoscopic IPOM technique was performed in all patients. The technique, epidemiological data, operative findings, hospital stay, morbidity, and …
Laparoscopic ileocecal resection in acute and chronic presentations of Crohn's disease. A single center experience
2017
Introduction The terminal ileum is the most involved tract in Crohn's disease. The obstruction in this location is the most frequent complication. Acute or chronic presentations can occur. Surgery finds a role in the management of chronic strictures and in acute clinical presentations with complications not improving with conservative therapy. Patients and methods We investigate the outcome of patients with obstruction of the ileo-cecal bowel tract laparoscopically managed. It was analyzed the average operative time (OT), the conversion rate and the occurrence of re-operation due to surgical complications. Results 21 patients underwent an ileocecal resection for complicated Crohn's disease …
Pattern and characteristics of advanced cancer patients admitted to hospices in Italy
2013
Abstract The aim of this multicenter study was to assess the pattern and the characteristics of advanced cancer patients admitted to hospices. A consecutive sample of patients admitted in a period of 6 months was taken into consideration. Two hundred thirty-six patients admitted to hospices were consecutively assessed. Ninety-six percent of patients were admitted in acute hospital in the previous 3 months, with a mean time spent in hospital of 34.5 days, and 47 % of patients had received chemotherapy the month before hospice admission. Thirty-four percent of patients for whom data were available had significant persistent pain, and 44 % of them presented episodes of breakthrough pain. Sixty…
Laparoscopy is an available alternative to open surgery in the treatment of perforated peptic ulcers: A retrospective multicenter study
2018
Abstract Background Perforated peptic ulcers (PPU) remain one of the most frequent causes of death. Their incidence are largely unchanged accounting for 2–4% of peptic ulcers and remain the second most frequent abdominal cause of perforation and of indication for gastric emergency surgery. The minimally invasive approach has been proposed to treat PPU however some concerns on the offered advantages remain. Methods Data on 184 consecutive patients undergoing surgery for PPU were collected. Likewise, perioperative data including shock at admission and interval between admission and surgery to evaluate the Boey’s score. It was recorded the laparoscopic or open treatments, the type of surgical …
