FIRST RECORD OF A NUCLEAR-FOLLOWER ASSOCIATION BETWEEN CORYDORAS VITTATUS (NIJSSEN, 1971), CORYDORAS CF. JULII (CALLICHTHYIDAE) AND KNODUS VICTORIAE (STEINDACHNER, 1907) (CHARACIDAE)
Nuclear-follower interactions are a particular type of interspecific foraging association which involves a nuclear species, which revolves or scans through the substrate, and follower species that access the food items made available by the nuclear species’ activity. This type of association was observed in a headwater stream at the Itapecuru basin, in the Maranhão cerrado, involving the catfishes Corydoras vittatus, Corydoras cf. julii as nuclear species and Knodus victoriae as its follower. Individuals of C. vittatus, Corydoras cf. julii revolved the substrate during their foraging, promoting sediment suspension. Their followers, in turn, moved through the “cloud” of particles in suspension, capturing food items. Food particles in suspension do not seem to be used by the catfishes but become available for K. victoriae. The follower behavior represents a feeding tactic for these species, reinforcing the general idea of behavioral plasticity between follower species
Schizophrenia and work: aspects related to job acquisition in a follow-up study
Objective: Work is considered one of the main forms of social organizationhowever, few individuals with schizophrenia find work opportunities. The purpose of this study was to evaluate the relationship between schizophrenia symptoms and job acquisition. Method: Fifty-three individuals diagnosed with schizophrenia from an outpatient treatment facility were included in an 18-month follow-up study. After enrollment, they participated in a prevocational training group. At the end of training (baseline) and 18 months later, sociodemographic, clinical data and occupational history were collected. Positive and negative symptoms (Positive and Negative Syndrome Scale - PANSS), depression (Calgary Depression Scale), disease severity (Clinical Global Impression - CGI), functionality (Global Assessment of Functioning - GAF), personal and social performance (Personal and Social Performance - PSP) and cognitive functions (Measurement and Treatment Research to Improve Cognition in Schizophrenia - MATRICS battery) were applied at baseline and at the end of the study. Results: Those with some previous work experience (n = 19) presented lower scores on the PANSS, Calgary, GAF, CGI and PSP scales (p < 0.05) than those who did not work. Among those who worked, there was a slight worsening in positive symptoms (positive PANSS). Conclusions: Individuals with less severe symptoms were more able to find employment. Positive symptom changes do not seem to affect participation at workhowever, this calls for discussion about the importance of employment support.Programa de Esquizofrenia (PROESQ)Centro de Atencao Integrada a Saude Mental (CAISM)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) [2011/50740-5]Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)FAPESPConselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)CAPESUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Fed Sao Carlos UFSCar, Dept Med, Sao Carlos, SP, BrazilUniv Fed Sao Carlos, Dept Terapia Ocupac, Sao Carlos, SP, BrazilFac Ciencias Med Santa Casa Sao Paulo, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilFAPESP [2011/50740-5]Web of Scienc
A triple-blinded crossover study to evaluate the short-term safety of sweet manioc starch for the treatment of glycogen storage disease type Ia
BACKGROUND: Glycogen storage disease type 1a (GSD Ia) is characterized by severe fasting hypoglycemia. The clinical management includes the administration of uncooked cornstarch (UCCS). Although such a diet approach is effective in achieving euglycemia, its impact on the quality of life of patients should be considered. In vitro analyses suggest a longer release of glucose when using sweet manioc starch (SMS). METHODS: We compared the efficacy and safety of the administration of SMS and UCCS during a short-fasting challenge in patients with GSD Ia in a randomized, triple-blind, phase I/II, cross-over study. GSD Ia patients aged ≥ 16 years and treated with UCCS were enrolled. Participants were hospitalized for two consecutive nights, receiving UCCS or SMS in each night. After the administration of the starches, glucose, lactate and insulin levels were measured in 1-h interval throughout the hospitalization period. The procedures were interrupted after 10 h of fasting or in a hypoglycemic episode ( 25 kg/m(2)) participated in the study. The average fasting period was 8.2 ± 2.0 h for SMS and 7.7 ± 2.3 h for UCCS (p = 0.04). SMS maintained euglycemia for a greater period over UCCS. Increased lactate concentrations were detected even in absence of hypoglycemia, not being influenced by the different starches investigated (p = 0.17). No significant difference was found in total cholesterol, HDL, triglycerides and uric acid levels in both arms. None of the patients showed severe adverse events. CONCLUSIONS: SMS appears to be non-inferior to UCCS in the maintenance of euglycemia, thus emerging as a promising alternative to the treatment of GSD Ia

Normalization of height and excess body fat in children with salt-wasting 21-hydroxylase deficiency
OBJECTIVE: To evaluate growth and body composition of patients with the salt wasting form of classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency and to compare them with healthy children. METHODS: Twenty-one prepubertal patients (eight boys and 13 girls) between 2.1 and 10.2 years and 67 prepubertal healthy controls (36 boys and 31 girls) between 1.2 and 11.7 years were included. Weight, height, upper-arm circumference, skinfolds, body composition determined by bioimpedance, and bone age were measured. The following data were obtained from the medical records: parents' height, serum levels of 17-hydroxyprogesterone and Δ4-androstenedione, prescribed hydrocortisone doses, weight and length at birth, in the beginning of the treatment, and at 2 years. RESULTS: Patients had lower weight and length z scores at the first appointment compared with the same data at birth, showing recovery after the beginning of the treatment without advanced bone age. Mean height z score was higher in controls (0.28±0.86) than in patients (-0.61±0.99, p < 0.001); this difference disappeared when the patients' height was adjusted to their bone age (0.33±1.68, p = 0.912). Patients had higher body mass index (p < 0.001), fat mass (p < 0.001), and fat mass index (p < 0.001) than controls. There was no difference in the skinfolds between the two groups (p = 0.157). CONCLUSIONS: Patients had growth recovery with mean height similar to the general population; however, they had higher body fat, which seems to be visceral, since there was no difference between the skinfolds of both groups.OBJETIVO: Avaliar crescimento e composição corporal de portadores da forma clássica perdedora de sal da hiperplasia adrenal congênita por deficiência da 21-hidroxilase, comparando-os com crianças saudáveis. MÉTODOS: Foram incluídos 21 pacientes (oito meninos e 13 meninas), entre 2,1 e 10,2 anos, e 67 controles pré-púberes (36 meninos e 31 meninas), entre 1,2 e 11,7 anos. Avaliou-se peso, estatura, perímetro braquial, dobras cutâneas, composição corporal por bioimpedância e idade óssea. Foram obtidas dos prontuários dos pacientes as seguintes informações: estatura dos pais, valores de 17-OH progesterona e Δ4-androstenediona, dose de hidrocortisona prescrita, dados de peso e estatura ao nascimento, no início do tratamento e aos 2 anos de idade. RESULTADOS: Os pacientes apresentaram menor escore z de peso e de altura na primeira consulta em relação à situação de nascimento, com posterior recuperação após o início do tratamento, sem apresentar avanço da idade óssea. A média do escore z da altura dos controles (0,28±0,86) foi maior que a dos casos (-0,61±0,99, p < 0,001). Essa diferença desaparece quando se ajusta a altura dos pacientes para a idade óssea (0,33±1,68, p = 0,912). Os pacientes apresentaram maiores índices de massa corporal (p < 0,001), massa gorda (p < 0,001) e índice de massa gorda (p < 0,001) do que os controles. Não houve diferença entre as dobras cutâneas dos 2 grupos (p = 0,157). CONCLUSÕES: Os pacientes apresentaram recuperação do crescimento com média de estatura semelhante à da população geral, porém com maior adiposidade corporal, que parece ser visceral, já que não houve diferença entre as dobras cutâneas.26326

CARACTERÍSTICAS HEMATOLÓGICAS DO PEIXE ORNAMENTAL AMAZÔNICO SYMPHYSODON AEQUIFACIATUS SUBMETIDO A CONDIÇÕES DE CATIVEIRO
A espécie Symphysodon aequifasciatus é uma das espécies de peixe ornamental de grande importância econômica no comércio nacional e internacional, no entanto, pouco se sabe sobre seus aspectos fisiológicos e sanitários dessa espécie em cativeiro. Nesse sentido, o objetivo do presente estudo foi determinar o perfil hematológico basal do acará disco mantido em cativeiro. Para isso, 14 animais adultos selvagens foram aclimatados em condições laboratoriais semelhantes às condições ambientais. O sangue dos peixes foi retirado por punção da veia caudal para as análises eritrocitárias, trombocitárias e leucocitárias. O resultado do hemograma mostrou maior frequência de linfócitos e ausência de eosinófilos, basófilos e LG-PAS, semelhante a resultados obtidos por outras espécies da família Cichlidae descritos na literatura. Não foi observada mortalidade indicando adaptação às condições de cativeiro refletido pelo exame sanguíneo normal
Estudio cualitativo sobre el activismo en torno al parto y al nacimiento respetado en la provincia de Entre Ríos, Argentina
Las organizaciones de mujeres lograron transformar experiencias vitales, tradicionalmente entendidas como personales y privadas, en asuntos públicos y políticos creando nuevas formas de actuación ciudadana. El embarazo, parto y la crianza forman parte de procesos de creciente politización. El objetivo del proyecto fue generar un conocimiento sistemático sobre los grupos y las asociaciones activistas de la provincia de Entre Ríos, sus prácticas en entornos online, y sobre los aspectos biográficos de las trayectorias vitales de las activistas. El estudio se desarrolló en varias fases, con combinación de estrategias metodológicas cualitativas. Entre los resultados está la descripción de las prácticas asamblearias y ciberactivista de seis grupos entrerrianos feministas que buscan generar redes con otros movimientos sociales e instituciones de salud y educación. Los estudios de las narrativas biográficas muestran tramas en las cuales se van articulando posicionamientos personales-biográficos con otros de índole social y política. Las valoraciones morales y afectivas aparecen en relación con la propia participación activista y los procesos de transformación social. Los activismos por el parto y el nacimiento respetado estudiados forman parte procesos de participación ciudadana, lo que las hace centrales en el campo de los derechos sexuales y reproductivos.

The germline mutational landscape of BRCA1 and BRCA2 in Brazil
The detection of germline mutations in BRCA1 and BRCA2 is essential to the formulation of clinical management strategies, and in Brazil, there is limited access to these services, mainly due to the costs/availability of genetic testing. Aiming at the identification of recurrent mutations that could be included in a low-cost mutation panel, used as a first screening approach, we compiled the testing reports of 649 probands with pathogenic/likely pathogenic variants referred to 28 public and private health care centers distributed across 11 Brazilian States. Overall, 126 and 103 distinct mutations were identified in BRCA1 and BRCA2, respectively. Twenty-six novel variants were reported from both genes, and BRCA2 showed higher mutational heterogeneity. Some recurrent mutations were reported exclusively in certain geographic regions, suggesting a founder effect. Our findings confirm that there is significant molecular heterogeneity in these genes among Brazilian carriers, while also suggesting that this heterogeneity precludes the use of screening protocols that include recurrent mutation testing only. This is the first study to show that profiles of recurrent mutations may be unique to different Brazilian regions. These data should be explored in larger regional cohorts to determine if screening with a panel of recurrent mutations would be effective.This work was supported in part by grants from Barretos Cancer Hospital (FINEP - CT-INFRA, 02/2010), Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP, 2013/24633-2 and 2103/23277-8), Fundação de Apoio à Pesquisa do Rio Grande do Norte (FAPERN), Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ), Fundação de Amparo à Pesquisa do Estado do Rio Grande do Sul (FAPERGS), Ministério da Saúde, the Breast Cancer Research Foundation (Avon grant #02-2013-044) and National Institute of Health/National Cancer Institute (grant #RC4 CA153828-01) for the Clinical Cancer Genomics Community Research Network.
