Agrofuel policies in Brazil: paradigmatic and territorial disputes

The expansion of agrofuel crops challenges us to rethink policies, territories, human agency, and the paradigms used to explain them. In Brazil, policies supporting the expansion of agrofuel crops and the intensification of agrofuel production are reorganising rural land use and undermining some forms of participation in the capitalist and family modes of production. To reflect on this new reality, we study peasant movement reactions, proposals, and territorial disputes with agribusiness. Using the Pontal do Paranapanema region of São Paulo state as a case in point, the paper analyses territorial disputes between expanding sugarcane plantations and agrarian reform settlements as well as biodiesel production projects developed by the Landless Workers Movement (MST) and the Western São Paulo Federation of Settlement and Family Farmer Associations (FAAFOP). It also analyses the agrofuel policies of other peasant organisations, including Via Campesina. The production of agrofuels has changed the processes of land acquisition and use by both agribusiness and the peasantry, provoking new insights into the nature of territorial conflicts and thereby stimulating the need to revise perspectives on the agrarian question in Brazil.

Efeito do aquecimento com corrida sobre a agilidade e a impulsão vertical em jogadores juvenis de futebol

The aim of this study was to evaluate the effect of warm-up on agility (AG) and on vertical jump (VJ) tests in youth soccer players. Sixteen players performed the AG and VJ tests without warm-up (NW) and with warm-up (WW) randomly, within two weeks, at least 48 h interval, during season. The warm-up was performed only a light running during 10 min. The paired t-test identified significant difference (p <0,05) between the NW and WW conditions in the tests of SR and CJ (9,14 +/- 0,28 vs 8,94 +/- 0,30 s e 51,4 +/- 4,2 vs 54,5 +/- 6,4 cm, respectively). The warm-up performed on light intensity running was effective to improve the AG and VJ tests performance in youth soccer players.

Body dysmorphic disorder among dermatologic patients: Prevalence and clinical features

Background: An impairing preoccupation with a nonexistent or slight defect in appearance is the core symptom of body dysmorphic disorder (ODD), a psychiatric condition common in dermatology settings.Objective: We sought to determine the prevalence of ODD in dermatologic patients, comparing general and cosmetic settings, and describing some demographic and clinical characteristics.Methods: In all, 300 patients were consecutively assessed. Screening and diagnoses were performed with validated instruments plus a best estimate diagnosis procedure. The final sample comprised 150 patients in the cosmetic group, 150 patients in the general dermatology group, and 50 control subjects. Standard statistical analyses were performed (chi(2), nonparametric tests, logistic regression).Results: The current prevalence was higher in the cosmetic group (14.0%) compared with general (6.7%) and control (2.0%) groups. No patient had a previous diagnosis. Frequently the reason for seeking dermatologic treatment was not the main ODD preoccupation. Patients with ODD from the cosmetic group were in general unsatisfied with the results of dermatologic treatments.Limitations: Cross-sectional study conducted in a university hospital is a limitation. It is uncertain if the findings can be generalized. Retrospective data regarding previous treatments are not free from bias.Conclusions: BUD is relatively common in a dermatologic setting, especially among patients seeking cosmetic treatments. These patients have some different features compared with general dermatology patients. Dermatologists should be aware of the clinical characteristics of ODD to identify and refer these patients to mental health professionals. (J Am Acad Dermatol 2010;63:235-43.)

BODY DYSMORPHIC DISORDER IN PATIENTS WITH OBSESSIVE-COMPULSIVE DISORDER: PREVALENCE and CLINICAL CORRELATES

Background The prevalence, sociodemographic aspects, and clinical features of body dysmorphic disorder (BDD) in patients with obsessivecompulsive disorder (OCD) have been previously addressed in primarily relatively small samples. Methods We performed a cross-sectional demographic and clinical assessment of 901 OCD patients participating in the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. We used the Structured Clinical Interview for DSM-IV Axis I Disorders; Yale-Brown Obsessive-Compulsive Scale; Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS); Brown Assessment of Beliefs Scale; Clinical Global Impression Scale; and Beck Depression and Anxiety Inventories. Results The lifetime prevalence of BDD was 12.1%. The individuals with comorbid BDD (OCD-BDD; n = 109) were younger than were those without it. In addition, the proportions of single and unemployed patients were greater in the OCD-BDD group. This group of patients also showed higher rates of suicidal behaviors; mood, anxiety, and eating disorders; hypochondriasis; skin picking; Tourette syndrome; and symptoms of the sexual/religious, aggressive, and miscellaneous dimensions. Furthermore, OCD-BDD patients had an earlier onset of OC symptoms; greater severity of OCD, depression, and anxiety symptoms; and poorer insight. After logistic regression, the following features were associated with OCD-BDD: current age; age at OCD onset; severity of the miscellaneous DY-BOCS dimension; severity of depressive symptoms; and comorbid social phobia, dysthymia, anorexia nervosa, bulimia nervosa, and skin picking. Conclusions Because OCD patients might not inform clinicians about concerns regarding their appearance, it is essential to investigate symptoms of BDD, especially in young patients with early onset and comorbid social anxiety, chronic depression, skin picking, or eating disorders.
