The ontogenesis of smiling and its association with mothers` affective behaviors: A longitudinal study

Two babies were observed from their third week to their sixth month of life. Our goals in the study were: to investigate developmental changes in smiling patterns; to analyze the smiling patterns observed in the presence of mother`s affective behaviors, and to verify whether the babies can answer contingently, with smiles, to mothers` affective behaviors. The babies and their mothers were videotaped at home. It was verified a positive linear trajectory tendency for the babies` smiles. The babies revealed a particular tendency to display one or two kinds of smiles. Babies answered contingently with smiles to their mothers` affective behaviors. Correlations between the most frequent types of babies` smiles and his/her mothers` smiles were verified (r = 37, p < .0017 - baby1, and r = .62, p < .0017 - baby2). Different types of smiles were exhibited by the babies as contingent answers to mothers` behaviors. The results show an association between babies` smiles and their mothers` affective behaviors.

Brazilian mothers` socialization goals: Intracultural differences in seven Brazilian cities

The present study aimed to investigate Brazilian mothers` socialization goals. The participants in the study were 349 primiparous mothers, whose ages ranged from 17 to 47 years (mean = 26.6 years), who had children aged between 1 and 48 months (mean = 16.4 months). The families were living in seven different cities representing each of the five geographical regions of the country. A scale to evaluate the families` socio-economic status and an interview about socialization goals were used. The answers were coded in five categories defined in previous studies: self-maximization, self-control, lovingness, proper demeanor, and decency. Comparison of the means showed that Brazilian mothers gave more emphasis to self-maximization and proper demeanor than to the other categories, presenting a pattern that fosters the development of children`s autonomous-relational selves. The intracultural variation found was related to the different cities studied. GLM results showed main effects of both city size and mothers` educational level on their socialization goals. These findings contribute to the understanding of characteristics of socialization goals related with autonomy and sociocentrism.

The Mother-Daughter Relationship in Eating Disorders: The Psychotherapy group of mothers

Psychotherapeutic interventions that bring about differentiation, separation, individuation and autonomy in the mother-daughter relationship are recommended as treatment for eating disorders. With this goal in mind, a psychotherapy group for mothers was organized in an outpatient program for adolescents with eating disorders at a public institution, as one of the psychotherapeutic approaches in the multidisciplinary treatment of adolescent patients. Evidence suggests that this approach can be relevant and effective in the treatment of eating disorders.

Abnormal resting state corticolimbic blood flow in depressed unmedicated patients with major depression: A 15O-H2O PET study

We investigated the differences in the resting state corticolimbic blood flow between 20 unmedicated depressed patients and 21 healthy comparisons. Resting state cerebral blood flow (CBF) was measured with H215O PET. Anatomical MRI scans were performed on an Elscint 1.9 T Prestige system for PET-MRI coregistration. Significant changes in cerebral blood flow indicating neural activity were detected using an ROI-free image subtraction strategy. In addition, the resting blood flow in patients was correlated with the severity of depression as measured by HAM-D scores. Depressed patients showed decreases in blood flow in right anterior cingulate (Brodmann areas 24 and 32) and increased blood flow in left and right posterior cingulate (Brodmann areas 23, 29, 30), left parahippocampal gyrus (Brodmann area 36), and right caudate compared with healthy volunteers. The severity of depression was inversely correlated with the left middle and inferior frontal gyri (Brodmann areas 9 and 47) and right medial frontal gyrus (Brodmann area 10) and right anterior cingulate (Brodmann areas 24, 32) blood flow, and directly correlated with the right thalamus blood flow. These findings support previous reports of abnormalities in the resting state blood flow in the limbic-frontal structures in depressed patients compared to healthy volunteers. Hum Brain Mapp, 2012.

Inflammatory milieu as an early marker of kidney injury in offspring rats from diabetic mothers

The present study investigated the early presence of inflammatory response in renal tissue of young offspring from diabetic mothers. The effect of L-arginine (L-arg) supplementation was also investigated. The offspring was divided into four groups: group CO (controls); group DO (diabetic offspring); group CA (CO receiving 2% L-arg solution) and group DA (DO receiving the 2% L-arg solution). Glycemia, arterial pressure and renal function were evaluated; gene and protein expression of pro-inflammatory cytokines were also measured. Blood pressure levels were significantly increased in 2 and 6 month-old DO rats, whereas L-arg administration caused a significant decrease in the DA group, at both ages. DO rats showed a significantly blunted glycemic response to exogenous insulin. In 2 month-old DO animals, renal protein expression of pro-inflammatory molecules was significantly increased. At six months of age, we also observed an increase in gene expression of pro-inflammatory molecules, whereas L-arg supplementation prevented this increase at both ages. Our data suggest that activation of inflammatory pathways is present early in the kidney of DO rats, and that L-arg can attenuate the expression of these markers of tissue inflammation. Our results also reinforce the concept that intrauterine environmental factors are a fundamental determinant in the development of metabolic and vascular diseases later in life.

DTI voxelwise analysis did not differentiate older depressed patients from older subjects without depression

Introduction: Neuroimaging has been widely used in studies to investigate depression in the elderly because it is a noninvasive technique, and it allows the detection of structural and functional brain alterations. Fractional anisotropy (FA) and mean diffusivity (MD) are neuroimaging indexes of the microstructural integrity of white matter, which are measured using diffusion tensor imaging (DTI). The aim of this study was to investigate differences in FA or MD in the entire brain without a previously determined region of interest (ROI) between depressed and non-depressed elderly patients. Method: Brain magnetic resonance imaging scans were obtained from 47 depressed elderly patients, diagnosed according to DSM-IV criteria, and 36 healthy elderly patients as controls. Voxelwise statistical analysis of FA data was performed using tract-based spatial statistics (TBSS). Results: After controlling for age, no significant differences among FA and MD parameters were observed in the depressed elderly patients. No significant correlations were found between cognitive performance and FA or MD parameters. Conclusion: There were no significant differences among FA or MD values between mildly or moderately depressed and non-depressed elderly patients when the brain was analyzed without a previously determined ROI.

Loss of interest, depressed mood and impact on the quality of life: Cross-sectional survey

Abstract Background Depressive symptoms and chronic disease have adverse effects on patients' health-related quality of life (H-RQOL). However, little is known about this effect on H-RQOL when only the two core depressive symptoms - loss of interest and depressed mood - are considered. The objective of this study is to investigate H-RQOL in the presence of loss of interest and depressed mood at a general medical outpatient unit. Methods We evaluated 553 patients at their first attendance at a general medical outpatient unit of a teaching hospital. H-RQOL was assessed with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Depressed mood and loss of interest were assessed by the Primary Care Evaluation of Mental Disorders (PRIME-MD)-Patient Questionnaire. A physician performed the diagnosis of chronic diseases by clinical judgment and classified them in 13 possible pre-defined categories. We used multiple linear regression to investigate associations between each domain of H-RQOL and our two core depression symptoms. The presence of chronic diseases and demographic variables were included in the models as covariates. Results Among the 553 patients, 70.5% were women with a mean age of 41.0 years (range 18-85, SD ± 15.4). Loss of interest was reported by 54.6%, and depressed mood by 59.7% of the patients. At least one chronic disease was diagnosed in 59.5% of patients; cardiovascular disease was the most prevalent, affecting 20.6% of our patients. Loss of interest and depressed mood was significantly associated with decreased scores in all domains of H-RQOL after adjustment for possible confounders. The presence of any chronic disease was associated with a decrease in the domain of vitality. The analysis of each individual chronic disease category revealed that no category was associated with a decrease in more than one domain of H-RQOL. Conclusion Loss of interest and depressed mood were associated with significant decreases in H-RQOL. We recommend these simple tests for screening in general practice.
