Developmental lead exposure induces depressive-like behavior in female rats

The involvement of neurotoxicants in the etiology of emotional pathologies is becoming an issue in neurotoxicology. Lead (Pb) exposure during childhood has been associated with increased impulsivity, aggressivity, and delinquency. Considering the paucity of experimental studies investigating the involvement of developmental Pb exposure in emotional disorders, our objective was to investigate whether Pb exposure during pregnancy and/or lactation could be related to depressive symptoms in adult male and female rats. Wistar dams received 10 mg of Pb, as Pb acetate, or 13.4 mg of Na acetate, by gavage, daily, during pregnancy and lactation. By cross-fostering at the time of birth, pups were either exposed to Ph or Na acetate during pregnancy only, lactation only, or during both pregnancy and lactation. At 70 days of age, animals were submitted to the open-field test followed by the forced swimming test. Ph levels were measured in the blood of dams (weaning) and pups (after behavioral evaluation). The results demonstrated that exposure to Ph during both pregnancy and lactation induced, in males, an increased emotionality state detected in the open-field test, and in females, depressive-like behavior detected in the forced swimming test. These alterations were observed at residual blood Pb levels (i.e., around 5 mug/dL).

O gênero nas ciências da saúde: produção e reprodução de concepções sobre a diferença entre homens e mulheres

The historical and social process has built models of masculinity and femininity that culminate in standards and norms to be followed by individuals in their social interactions. In recent decades studies based on the discussions that originated in the feminist movement have been investigating how social institutions, including medicine and other health sciences, have established standards of masculinity and femininity throughout the history, nurturing this sexist discourse on common sense and sciences. Social roles are assigned to the genera specifying rigid boundaries of behavior and social control. The notion of the female predisposition to physical and emotional disorders has prompted speculation within academic strands culminating in the creation of specialized medical illness that would prevent the female, the male permeated by notions of endurance and strength has become synonymous of a healthy body, confirming the male domination and the economic and political role of men. This research concerned to study and investigate through semi-structured interviews and content analysis, conceptions of gender and the differences between men and women in reports of 11 health professionals. The results indicate that in large part the conceptions of health professionals reproduce the hegemonic discourse about what being a man and woman. Further research could investigate the relationship between women and men with health care as well the care provided by health professionals

EMOTIONAL BURDEN IN CAREGIEVERS of PATIENTS WITH OBSESSIVE-COMPULSIEVE DISORDER

The objective of this study was to evaluate the emotional burden, psychological morbidity, and level of family accommodation in caregivers of obsessive-compulsive disorder (OCD) patients, according to sociodemographic and clinical factors. Methods: Fifty Brazilian DSM-IV OCD patients and their caregivers were evaluated using the Family Accommodation Scale, the Zarit Burden Interview (ZBI), the Self-Report Questionnaire (caregivers), the Yale-Brown Obsessive-Compulsive Scale, and the Beck Depression Inventory (patients). Most caregivers (80%) were aged between 30 and 59 years and lived with the patient (88%). Results: Forty-two percent presented a common mental disorder and their mean ZBI score was 28.9. Family accommodation was moderate in 26% and severe or very severe in 24%. Caregivers' levels of psychological morbidity, accommodation, and emotional burden were associated with each other and with the severity of patient obsessive-compulsive and depressive symptoms. Conclusions: The results suggest that caregivers of OCD patients have important levels of burden and psychological morbidity and should receive orientation and support to minimize this emotional impact.

Emotional assessment of patients with oral lichen planus

Background Oral lichen planus is a chronic immune-mediated disease with an estimated prevalence of 0.5-2.5% in the general population. Patients with oral lichen planus are often emotionally unstable and anxious and may develop concomitant systemic disorders. The objective of this study was to evaluate emotional characteristics of patients with oral lichen planus.Methods Two groups were studied: the first group consisted of 48 patients with a diagnosis of oral lichen planus, and the second group consisted of controls without the disease matched for age and gender at a proportion of 1 : 1. The emotional state of the patients was evaluated using the State-Trait Anxiety Inventory, SF-36 generic quality of life questionnaire, and the Self Reporting Questionnaire-20.Results and conclusions The present investigation demonstrated the presence of anxiety and depression in patients with oral lichen planus and a negative impact of the disorder on the patient's quality of life as indicated by impairment of the physical aspect, vitality, mental health, and social aspect domains. This could indicate that associated psychological treatment may be important in the follow-up of these patients.
