Temperament and character in obese women with and without binge eating disorder

Obesity is a serious disorder and its treatment involves dietitians, psychologists, and psychiatrists, often with a poor outcome. The role of psychiatric issues in obesity is equivocal, and so is the fact whether emotional and behavioral disturbances are causes or consequences of an individual's overweight condition. We performed a study that included 120 obese women (59 with binge eating disorder [BED] and 61 with non-BED) according to specific selection criteria, and compared to 80 healthy controls. Body mass index (BMI) was calculated for all patients and they were assessed with the Temperament and Character Inventory (TCI). Despite the fact that obese patients with BED and without BED display a similar personality profile, those with BED show lower scores in Self-Directedness (SD). Both groups of obese patients differ from nonobese controls in Novelty Seeking (NS), Harm Avoidance (HA), Cooperativeness (C), and SD. SD seems to be the strongest predictor for the development of BED. The idea that two distinct groups of obese patients exist is supported. Moreover, as regards personality, a lower SD and a higher risk of Personality Disorders were found in obese BED patients. Different severities of overweight do not seem to relate to a specific personality susceptibility.     

Italian multicentric pilot study on MBL2 genetic polymorphisms in HIV positive pregnant women and their children.

OBJECTIVE: We investigated genetic polymorphisms of MBL2 gene, in a cohort of 90 Italian HIV-1 pregnant seropositive women and their children in order to understand whether the MBL2 genotype of HIV-1 positive mothers might be related to their ability to transmit the virus to their children. MATERIALS AND METHODS: DNA was extracted from Iso Code Stix cards, and MBL2 genotyping was performed by Melting Temperature Assay. RESULTS: The frequency of the MBL2 0/0 homozygotes was higher in HIV-1 positive mothers than in healthy controls, the MBL2 0/0 genotype was more frequent in children born from HIV positive mothers than healthy subjects. CONCLUSIONS: We have confirmed the association of polymorphisms involving a gene of the innate immunity with an increased risk of being infected by HIV. These polymorphisms were also evidenced in children born from HIV+ mothers, but the risk of infection was strongly reduced by cesarean delivery and by antiretroviral treatment.     

High concentrations of activin A in the peritoneal fluid of women with epithelial ovarian cancer

OBJECTIVE: The aim of the present study was to evaluate the concentrations of activin A in the peritoneal fluid of women with epithelial (serous) ovarian cancer. METHODS: A group of 160 women was studied and divided in four subgroups as follows: 1) serous ovarian carcinoma (n = 32); 2) serous ovarian cystadenoma (n = 20); 3) endometriosis (n = 53); and 4) healthy controls (n = 55), including both fertile (n = 32) and postmenopausal women (n = 23). Specimens of peritoneal fluid were collected during surgical interventions, and activin A was quantified using a specific two-site enzyme immunoassay. RESULTS: Peritoneal fluid activin A concentrations in women with ovarian carcinoma were about five-fold higher than those found in the control group (median [interquartile range] = 7.60 [2.85-10.15] and 1.50 [1.00-2.50] ng/mL, respectively, P <.001). In contrast, the women with benign serous cystadenoma had peritoneal fluid activin A concentrations (1.50 [1.0-2.70] ng/mL) similar to those of the control group. High peritoneal fluid activin A levels (>2 multiples of the mean) distinguished carcinoma from cystadenoma with a sensitivity of 72% and a specificity of 80%. The follow-up of nine patients with stage IIIc ovarian cancer showed no apparent relationship between the peritoneal fluid activin A levels and overall survival. No significant difference in peritoneal fluid activin A concentrations between patients with endometriosis and control women was observed. CONCLUSION: Most women with serous ovarian carcinoma had high concentrations of activin A in the peritoneal fluid, supporting a possible role of this growth factor in ovarian cancer.     

An open-label, comparative study of the efficacy and safety of once-daily dose of enoxaparin versus unfractionated heparin in the treatment of proximal lower limb deep-vein thrombosis

BACKGROUND: Treatment of deep-vein thrombosis (DVT) with a once-daily regimen of enoxaparin, rather than a continuous infusion of unfractionated heparin (UFH) is more convenient and allows for home care in some patients. This study was designed to compare the efficacy and safety of these two regimens for the treatment of patients with proximal lower limb DVT. METHODS: 201 patients with proximal lower limb DVT from 13 centers in Brazil were randomized in an open manner to receive either enoxaparin [1.5 mg/kg subcutaneous (s.c.) OD] or intravenous (i.v.) UFH (adjusted to aPTT 1.5-2.5 times control) for 5-10 days. All patients also received warfarin (INR 2-3) for at least 3 months. The primary efficacy endpoint was recurrent DVT (confirmed by venography or ultrasonography), and safety endpoints included bleeding and serious adverse events. The rate of pulmonary embolism (PE) was also collected. Hospitalization was at the physician's discretion. RESULTS: Baseline patient characteristics were comparable between groups. The duration of hospital stay was significantly shorter with enoxaparin than with UFH (3 versus 7 days). In addition, 36% of patients receiving enoxaparin did not need to be hospitalized, whereas all of the patients receiving UFH were hospitalized. The treatment duration was slightly longer with enoxaparin (8 versus 7 days). There was a nonsignificant trend toward a reduction in the rate of recurrent DVT with enoxaparin versus UFH, and similar safety. CONCLUSIONS: A once-daily regimen of enoxaparin 1.5 mg/kg subcutaneous is at least as effective and safe as conventional treatment with a continuous intravenous infusion of UFH. However, the once daily enoxaparin regimen is easier to administer (subcutaneous versus intravenous), does not require aPTT monitoring, and leads to both a reduced number of hospital admissions and an average 4-day-shorter hospital stay.     

Neuronal NOS activation during oxygen and glucose deprivation triggers cerebellar granule cell death in the later reoxygenation phase

The present study investigated the temporal relationship between neuronal nitric oxide synthase (nNOS) activity and expression and the development of neuronal damage occurring during anoxia and anoxia followed by reoxygenation. For this purpose, cerebellar granule cells were exposed to 2 hr of oxygen and glucose deprivation (OGD) and 24 hr of reoxygenation. To clarify the consequences of nNOS activity inhibition on neuronal survival, cerebellar granule cells were exposed to OGD, both in the absence of extracellular Na(+) ([Na(+)](e)), a condition that by reducing intracellular Ca(2+) ([Ca(2+)](I)) prevents Ca(2+)-dependent nNOS activation, and in the presence of selective and nonselective nNOS inhibitors, such as N(omega)-L-allyl-L-arginine (L-ALA), N(omega)-propyl-L-arginine (NPLA), and L-nitro-arginine-methyl-ester (L-NAME), respectively. The results demonstrated that the removal of [Na(+)](e) hampered the [Ca(2+)](i) increase and decreased expression and activity of nNOS. Similarly, the increase of free radical production present in cerebellar neurons, exposed previously to OGD and OGD/reoxygenation, was abolished completely in the absence of [Na(+)](e). Furthermore, the absence of [Na(+)](e) in cerebellar neurons exposed to 2 hr of OGD led to the improvement of mitochondrial activity and neuronal survival, both after the OGD phase and after 24 hr of reoxygenation. Finally, the exposure of cerebellar neurons to L-ALA (200 nM), and L-NAME (500 microM) was able to effectively reduce NO(*) production and caused an increase in mitochondrial oxidative activity and an improvement of neuronal survival not only during OGD, but also during reoxygenation. Similar results during OGD were obtained also with NPLA (5 nM), another selective nNOS inhibitor. These data suggest that the activation of nNOS is highly accountable for the neuronal damage occurring during the OGD and reoxygenation phases.     

Prevalence of urinary incontinence in young and middle-aged women in an Italian urban area

OBJECTIVE: To investigate by questionnaire the prevalence and characteristics of urinary incontinence (UI) in a female population aged between 18 and 49. STUDY DESIGN: Of 44,095 females aged 18-49.9 living in our urban area a sample of 10,000 subjects was sent a questionnaire and 3557 replied. The age-based analysis was performed on 2900 of these. RESULTS: The overall prevalence of UI was 20%. 11% had suffered from nocturnal enuresis before 18 years old, 47% of parous women noted a relationship between the beginning of UI and delivery. Among the incontinent women 83% lost urine with physical exertion, and 44% had urge incontinence, 18% used diapers, 20% had consulted a physician and half of these had been referred for medical, surgical or rehabilitative therapy, 50% reported past or present urinary infections, 8% complained also of faecal incontinence, 22% considered loss of urine embarrassing and humiliating but only 6% revealed frustration and 2% were obliged to stay at home for long periods of time. Of the incontinents 62% defined themselves anxious or nervous and 22% of these ascribed an increase of urinary leakage to anxiety or to nervousness, 9% reported use of antidepressant drugs, 85% had sexual intercourse and only 2% considered UI as an impediment to a satisfying sexual activity. CONCLUSIONS: UI is a common problem in young women. Urge incontinence seems to be prevalent in <30 aged women while stress incontinence occurs more frequently after this age.     

Perineal evaluation in the puerperium. Role of testing with a cotton-tipped swab

OBJECTIVE: To verify the applicability and significance of testing with a cotton-tipped swab in postpartum evaluation. STUDY DESIGN: One hundred seventy-eight puerperas were examined two months after vaginal delivery and underwent testing with a cotton-tipped swab, digital test, vaginal manometry and uroflowmetric urine stream interruption test. Statistical analysis was performed using Student's t test to evaluate the difference between mean values of continent and incontinent puerperas and the Bravais-Pearson coefficient to test the correlation between all the tests used in the study. RESULTS: Incontinent puerperas and multiparas had significantly higher swab test values than did continent and primiparas, who demonstrated a swab test mean value of 39.5 degrees during the Valsalva maneuver. The sensitivity of the swab test for stress urinary incontinence was 82.5%, while its specificity and positive predictive value were, respectively, 31.1% and 25.8%. CONCLUSION: Perineal damage occurs not only in symptomatic puerperas but most women. The swab test was unable to assess stress urinary incontinence in postpartum women, also, and demonstrated only urethral hypermobility. The swab test in the puerperium does not add significant information about pelvic floor performance and should not be used routinely postpartum.     

Use of reboxetine in bulimia nervosa: a pilot study

The pharmacological approach to bulimia nervosa is mainly based (BN) on selective serotonin reuptake inhibitors, but many elements suggest the possible involvement of the noradrenergic system in this disorder. The aim of the study was to assess the efficacy of reboxetine--a selective norepinephrine uptake inhibitor--in a sample of bulimic outpatients, after 3 months of treatment. Twenty-eight of 77 consecutively admitted patients with a DSM-IV diagnosis of BN (without Axis I comorbidity) received reboxetine. All patients were assessed at baseline (T0), and after 1 month (T1) and 3 months (T3), respectively, of treatment with reboxetine 4 mg/day. The subjects were administered the following questionnaires: Hamilton Rating Scale for Anxiety (HAM-A) and for Depression (HAM-D), Global Assessment Functioning (GAF), Eating Disorder Inventory-2 (EDI-2) and Body Shape Questionnaire (BSQ). Sixty percent of the patients were responsive to treatment(evaluated as a 50% decrease of bulimic behaviours). After 3 months of treatment, a significant reduction emerged in the scores of various EDI-2 subscales (Bulimia, Drive for Thinness, Body Dissatisfaction, Social Insecurity, Interpersonal Distrust, etc.) and in the BSQ total score. Moreover, depressive symptoms (HAM-D) and Global Functioning (GAF) scores showed a significant improvement. These data support a fast and favourable effect of reboxetine in the treatment of BN, both on symptoms and psychopathological features. Moreover, the specific and strong action of reboxetine on improvement of social functioning is also supported in this disorder.     

Temperament and character profile of eating disorders: a controlled study with the Temperament and Character Inventory

OBJECTIVE: The question whether anorexia nervosa (AN) and bulimia nervosa (BN) are different disorders or the extremes of a psychopathologic spectrum still has no definite answer. A way to face this problem is to examine the personality traits underlying these disorders. METHOD: The Temperament and Character Inventory (TCI) was administered to 141 anorectics (70 Restrictor and 71 Binge-purging), to 102 bulimics, and to 100 controls. The Temperament and Character Inventory main scales are Novelty Seeking, Harm Avoidance, Reward Dependence, Persistence, Self-Directedness, Cooperativeness, and Self-Transcendence. RESULTS: The personality profiles that emerged are characterized by low Novelty Seeking, high Harm Avoidance, high Persistence, and low Self-Directedness in AN, and by high Novelty Seeking, high Harm Avoidance, and low Self-Directedness in BN. Binge-purging anorectics showed a personality profile midway between anorectics and bulimics. DISCUSSION: The dimensional study of personality through the TCI and its facets seems effective in discriminating the personality traits underlying the different subtypes of Eating Disorders. The hypothesis of an Eating Disorders spectrum and its clinical implications are discussed.
