Alleles and haplotypes of the estrogen receptor alpha gene are associated with an increased risk of spontaneous abortion.

2010

Objective To investigate whether polymorphisms in estrogen receptor alpha (ERα) or beta (ERβ) genes are associated with a risk of miscarriage. Design A retrospectively analyzed, prospectively obtained database of cases and controls. Setting University hospital menopause unit. Patient(s) 177 women with at least one spontaneous abortion and 442 controls with at least one live birth and no history of miscarriage. Intervention(s) None. Main Outcome Measure(s) Genotype frequencies and odd ratios for abortion risk in cases and controls for four single nucleotide polymorphisms (SNPs) located in intron 1 (C>T and A>G), intron 4 (A>T), and exon 8 (T>C) for the ERα gene, and two SNPs located in intro…

Association analysis between gene variants of the tyrosine hydroxylase and the serotonin transporter in borderline personality disorder.

2010

For patients with borderline personality disorder (BPD), we previously reported an independent effect of the catechol-o-methyl-transferase (COMT) low-activity (Met(158)) allele and an interaction with the low-expression allele of the deletion/insertion (short/long or S/L, resp.) polymorphism in the serotonin transporter-linked promoter region (5-HTTLPR). The purpose of the present study was to extend these findings to the tyrosine hydroxylase (TH) Val(81)Met single nucleotide polymorphism (SNP), the 5-HTTLPR S/L polymorphism incorporating the recently described functional A/G SNP within the long allele of the 5-HTTLPR (rs25531) as well as the variable number of tandem repeat (VNTR) polymorp…

Laryngopharyngeal reflux as a potential cause of persistent local neck symptoms after total thyroidectomy

2020

Abstract Purpose Local neck symptoms (LNS) may be related to goiter, but are also reported by patients suffering from laryngeal–pharyngeal reflux (LPR). The aim of this study was to investigate whether LPR could play a role in the persistence of some LNS after total thyroidectomy (TT). Methods A consecutive case series of 160 patients with multinodular goiter (MNG) candidate for TT were included in this study. Each patient was closely studied for both the thyroid pathology and reflux disease before and 6 months after surgery to assess the persistence of LNS after surgery. Results Only throat discomfort showed a significant improvement (p  = 0.031) after surgery. On the other hand, swallowin…

Antibody Pattern of HCV Infection and Hepatocellular Carcinoma in Italy: A Case Control Study

1994

The association of hepatitis C virus (HCV) infection with hepatocellular carcinoma (HCC) and the presence of a specific antibody pattern was assessed by means of a case-control study conducted in Italy on 65 consecutive newly diagnosed HCC cases and 99 sex- and age-matched control patients with chronic nonhepatic disease. The prevalences of antibody to HCV (anti-HCV) and hepatitis B surface antigen (HBsAg) observed were 66.2% and 24.6%, respectively. The relative risk for the association of each of the two markers with HCC, as calculated by multiple logistic analysis, was 26.9 (95% confidence intervals (CI): 9.9–72.5) for anti-HCV and 11.4 (95% CI: 3.1–41.1) for HBsAg. Thus, they constitute…

Social functioning as a significant factor in women's help-seeking behaviour during the climacteric period.

1993

In order to identify the psychosocial factors that lead to the demand for medical care related to the menopause, we carried out a case/control study. A case was defined as a woman who sought gynaecological care due to "menopausal complaints" (n = 85) and a control referred to a woman drawn at random from the general population. The cases showed greater psychiatric morbidity and social dissatisfaction, a lower level of diffused social support and a higher frequency of severe life events and the controls showed greater social maladjustment in objective conditions. The multivariate analysis (logistic regression) carried out after adjusting all the relevant variables, indicated that the demand …

Intra- and inter-foot coordination in quiet standing: footwear and posture effects.

2012

Intra-foot coordination between center of pressure (COP) of the ball and heel of the foot in single leg standing and inter-foot coordination of the right and left foot during bipedal stance was examined as a function of postural stance (two legs, one leg, and toe postures), footwear (barefoot, different area based high heel shoes) and postural training (ballet group and regular exercising group). Young adult females performed three 20s trials in each postural condition. In general, the traditional variability measures of COPnet motion increased under the less stable postural support conditions and ballet dancers had better balance in single leg standing. Regularity analysis revealed a negat…

Near-Infrared Hemoencephalography for Monitoring Blood Oxygenation in Prefrontal Cortical Areas in Diagnosis and Therapy of Developmental Dyslexia

2013

The purpose of this study was to check empirically the relevance of the near-infrared hemoencephalography (NIR-HEG), which assesses local brain blood oxygenation, in facilitation of the diagnosis and behavioral therapy in dyslexics. The study was carried out in children and teenagers with physiologically recognized dyslexia, of three increasing age-groups: 6–7, 9–10, and 19–20 years old. Healthy age- and gender-matched subjects were used as controls. Left and right prefrontal cortical areas were targeted for the NIR-HEG measurements that were taken at baseline in both controls and dyslexics and then after a 10-day course of midriff breathing exercise combined with a standard vocal and writi…

Aging of the liver: Age-associated mitochondrial damage in intact hepatocytes

1996

Mitochondrial damage may be a major cause of cellular aging. So far, this hypothesis had only been tested using isolated mitochondria. The aim of this study was to investigate the involvement of mitochondria in aging using whole liver cells and not isolated mitochondria only. Using flow cytometry, we found that age is associated with a decrease in mitochondrial membrane potential (30%), an increase in mitochondrial size, and an increase in mitochondrial peroxide generation (23%). Intracellular peroxide levels were also increased. The number of mitochondria per cell and inner mitochondrial membrane mass did not change. Gluconeogenesis from glycerol or fructose (mitochondrial-independent) did…

Comparison of the main oesophageal pathophysiological characteristics between short- and long-segment Barrett's oesophagus

2002

Aim: To assess the oesophageal manometric characteristics and 24-h pH profiles of patients with both short-segment and long-segment Barrett's oesophagus and compare them with those of patients with reflux oesophagitis and controls. Methods: Seventy-nine patients who had undergone upper digestive endoscopy were recruited: 16 had short-segment Barrett's oesophagus, 13 had long-segment Barrett's oesophagus, 25 had grade III oesophagitis according to the Savary–Miller classification and 25 were used as controls. The diagnosis of Barrett's oesophagus was based on the histological detection of specialized intestinal metaplasia, which extended  3 cm in patients with long-segment disease. All subje…
