Glycemia and prognosis of patients with chronic heart failure-Subanalysis of the Long-term Prospective Randomized Controlled Study Using Repetitive Education at Six-Month Intervals and Monitoring for Adherence in Heart Failure Outpatients (REMADHE) trial

Background Heart failure and diabetes often occur simultaneously in patients, but the prognostic value of glycemia in chronic heart failure is debatable. We evaluated the role of glycemia on prognosis of heart failure. Methods Outpatients with chronic heart failure from the Long-term Prospective Randomized Controlled Study Using Repetitive Education at Six-Month Intervals and Monitoring for Adherence in Heart Failure Outpatients (REMADHE) trial were grouped according to the presence of diabetes and level of glycemia. All-cause mortality/heart transplantation and unplanned hospital admission were evaluated. Results Four hundred fifty-six patients were included (135 [29.5%] female, 124 [27.2%] with diabetes mellitus, age of w50.2 +/- 11.4 years, and left-ventricle ejection fraction of 34.7% +/- 10.5%). During follow-up (3.6 +/- 2.2 years), 27 (5.9%) patients were submitted to heart transplantation and 202 (44.2%) died; survival was similar in patients with and without diabetes mellitus. When patients with and without diabetes were categorized according to glucose range (glycemia <= 100 mg/dL [5.5 mmol/L]), as well as when distributed in quintiles of glucose, the survival was significantly worse among patients with lower levels of glycemia. This finding persisted in Cox proportional hazards regression model that included gender, etiology, left ventricle ejection fraction, left ventricle diastolic diameter, creatinine level and beta-blocker therapy, and functional status (hazard ratio 1.45, 95% CI 1.09-1.69, P = .039). No difference regarding unplanned hospital admission was found. Conclusion We report on an inverse association between glycemia and mortality in outpatients with chronic heart failure. These results point to a new pathophysiologic understanding of the interactions between diabetes mellitus, hyperglycemia, and heart disease. (Am Heart J 2010; 159: 90-7.)

Sensitivity to halothane and its relationship to the development of PSE (Pale, Soft, Exudative) meat in female lineage broilers

This work aimed to evaluate female lineage broilers for halothane sensitivity and for their susceptibility to the subsequent development of PSE meat. The halothane test was carried out in an anesthetic chamber with 3.0% halothane. The unconscious birds were examined for leg muscle rigidity. If one or both legs became extended and rigid, the birds were classified as halothane sensitive (HAL+), while unresponsive birds were classified as halothane negative (HAL-). The results showed that of 298 birds aged 42 days old, 95.6% were HAL- and 4.4% were HAL+. A sample of pectoralis major muscle was collected from HAL- (n=105) and HAL+ (n=13) birds. The pH and breast fillet color were determined at 4ºC, 24 hours post-mortem. Interestingly, only 2.5% of HAL+ birds displayed PSE meat characteristics compared to 12.7% of HAL- individuals. The halothane test demonstrated that female lineage broilers displayed very little sensitivity towards halothane, indicating that the development of PSE meat is related to other environmental factors.

Immature stages of the moth Lobeza dentilinea (Lepidoptera: Notodontidae), with redescription of the species based on male and female morphology

Egg and pupa of Lobeza dentilinea Schaus, 1901 are described and illustrated for the first time. Eggs are smooth, dome-shaped, and greenish at oviposition. Last instar larvae have an aposematic coloration and the chaetotaxy is very similar to other notodontines, except for the number of lateral setae: L. dentilinea has three instead of four lateral setae on abdominal segments A3-A6. Pupae are light brown and typical of the family, with the last abdominal segments broadly round. Evidence from the adult morphology supporting the placement of the genus in Notodontinae includes proboscis smaller than the length of the head, epiphysis with more than half the length of tibia, tarsal claws simple, and labial palpi short. Male and female are confidently associated, and a redescription of the species is presented based on both sexes. Larvae of L. dentilinea are here recorded feeding on a Melastomataceae.

Time course of training-induced microcirculatory changes and of vegf expression in skeletal muscles of spontaneously hypertensive female rats

Exercise-induced vessel changes modulate arterial pressure (AP) in male spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) is important for angiogenesis of skeletal muscle. The present study evaluated the time course of VEGF and angiogenesis after short- and long-term exercise training of female SHR and Wistar Kyoto (WKY) rats, 8-9 weeks (200-250 g). Rats were allocated to daily training or remained sedentary for 3 days (N = 23) or 13 weeks (N = 23). After training, the carotid artery was catheterized for AP measurements. Locomotor (tibialis anterior and gracilis) and non-locomotor skeletal muscles (temporalis) were harvested and prepared for histologic and protein expression analyses. Training increased treadmill performance by all groups (SHR = 28%, WKY = 64%, 3 days) and (SHR = 141%, WKY = 122%, 13 weeks). SHR had higher values of AP than WKY (174 ± 4 vs 111 ± 2 mmHg) that were not altered by training. Three days of running increased VEGF expression (SHR = 28%, WKY = 36%) simultaneously with an increase in capillary-to-fiber ratio in gracilis muscle (SHR = 19%, WKY = 15%). In contrast, 13 weeks of training increased gracilis capillary-to-fiber ratio (SHR = 18%, WKY = 19%), without simultaneous changes in VEGF expression. Training did not change VEGF expression and capillarity of temporalis muscle. We conclude that training stimulates time- and tissue-dependent VEGF protein expression, independent of pressure levels. VEGF triggers angiogenesis in locomotor skeletal muscle shortly after the exercise starts, but is not involved in the maintenance of capillarity after long-term exercise in female rats.

Simvastatin-induced cardiac autonomic control improvement in fructose-fed female rats

OBJECTIVE: Because autonomic dysfunction has been found to lead to cardiometabolic disorders and because studies have reported that simvastatin treatment has neuroprotective effects, the objective of the present study was to investigate the effects of simvastatin treatment on cardiovascular and autonomic changes in fructose-fed female rats. METHODS: Female Wistar rats were divided into three groups: controls (n=8), fructose (n=8), and fructose+ simvastatin (n=8). Fructose overload was induced by supplementing the drinking water with fructose (100 mg/L, 18 wks). Simvastatin treatment (5 mg/kg/day for 2 wks) was performed by gavage. The arterial pressure was recorded using a data acquisition system. Autonomic control was evaluated by pharmacological blockade. RESULTS: Fructose overload induced an increase in the fasting blood glucose and triglyceride levels and insulin resistance. The constant rate of glucose disappearance during the insulin intolerance test was reduced in the fructose group (3.4+ 0.32%/min) relative to that in the control group (4.4+ 0.29%/min). Fructose+simvastatin rats exhibited increased insulin sensitivity (5.4+0.66%/min). The fructose and fructose+simvastatin groups demonstrated an increase in the mean arterial pressure compared with controls rats (fructose: 124+2 mmHg and fructose+simvastatin: 126 + 3 mmHg vs. controls: 112 + 2 mmHg). The sympathetic effect was enhanced in the fructose group (73 + 7 bpm) compared with that in the control (48 + 7 bpm) and fructose+simvastatin groups (31+8 bpm). The vagal effect was increased in fructose+simvastatin animals (84 + 7 bpm) compared with that in control (49 + 9 bpm) and fructose animals (46+5 bpm). CONCLUSION: Simvastatin treatment improved insulin sensitivity and cardiac autonomic control in an experimental model of metabolic syndrome in female rats. These effects were independent of the improvements in the classical plasma lipid profile and of reductions in arterial pressure. These results support the hypothesis that statins reduce the cardiometabolic risk in females with metabolic syndrome.

Self-disclosure of HIV diagnosis to sexual partners by heterosexual and bisexual men: a challenge for HIV/AIDS care and prevention

This study investigated the disclosure of HIV-positive serostatus to sexual partners by heterosexual and bisexual men, selected in centers for HIV/AIDS care. In 250 interviews, we investigated disclosure of serostatus to partners, correlating disclosure to characteristics of relationships. The focus group further explored barriers to maintenance/establishment of partnerships and their association with disclosure and condom use. Fear of rejection led to isolation and distress, thus hindering disclosure to current and new partners. Disclosure requires trust and was more frequent to steady partners, to partners who were HIV-positive themselves, to female partners, and by heterosexuals, occurring less frequently with commercial sex workers. Most interviewees reported consistent condom use. Unprotected sex was more frequent with seropositive partners. Suggestions to enhance comprehensive care for HIV-positive men included stigma management, group activities, and human rights-based approaches involving professional education in care for sexual health, disclosure, and care of "persons living with HIV".

Comportamento de risco para transtorno alimentar em universitárias brasileiras

CONTEXTO: Comportamentos de risco para transtornos alimentares envolvem atitudes e práticas inadequadas para com o alimento e o peso e podem ser avaliados com base em instrumentos validados. OBJETIVOS: Avaliar comportamento de risco para transtornos alimentares em universitárias brasileiras das cinco regiões do país. MÉTODOS: 2.483 universitárias responderam ao Teste de Atitudes Alimentares (EAT-26) nas cinco regiões. A pontuação no teste foi comparada entre as regiões por meio do teste qui-quadrado. Possíveis associações ou correlações com curso de graduação, idade, estado nutricional, renda individual e escolaridade do chefe da família foram avaliadas pelos coeficientes de Pearson e Spearman. Uma análise de covariância comparou o escore do EAT entre as regiões. RESULTADOS: A frequência de comportamento de risco para transtornos alimentares variou de 23,7% a 30,1% nas cinco regiões e não houve diferença na pontuação média do EAT e na proporção de escores positivos para comportamento de risco entre as regiões. Não houve forte correlação do escore do EAT com nenhuma das variáveis. CONCLUSÃO: Universitárias brasileiras apresentam alta frequência de comportamentos de risco para TA em todas as regiões do país. Medidas de prevenção devem ser planejadas para a população jovem feminina do Brasil.

Adiposidade em adolescentes e obesidade materna

OBJETIVO: Descrever a relação entre adiposidade na adolescência e obesidade materna. MÉTODOS: Foi realizado estudo transversal com 660 indivíduos de 8 a 18 anos, de ambos os sexos, matriculados em uma escola pública e outra privada do município de São Paulo. A coleta de dados foi realizada por meio de entrevista, medidas antropométricas e inquérito alimentar. A adiposidade na adolescência foi mensurada a partir do índice de massa corporal e, por meio de análise de regressão, verificou-se sua relação com a obesidade materna, ajustada por sexo, idade, estágio de maturação sexual, valor energético total da dieta, atividade física, sedentarismo, peso ao nascer e escolaridade materna. RESULTADOS: Dos adolescentes estudados, 64,7% eram do sexo feminino. A média (desvio-padrão) de idade foi de 12,4 (1,80), variando de 8 a 17 anos. Verificou-se maior prevalência de excesso de peso e obesidade entre os indivíduos do sexo masculino, não sendo observada associação significativa entre estado nutricional e sexo. Após ajuste pelas covariáveis, detectou-se que filhos de mães obesas têm risco quatro vezes maior de ser obesos, quando comparados aos adolescentes filhos de mães não obesas. CONCLUSÃO: Conclui-se que a obesidade materna representa fator de risco importante para o desenvolvimento da obesidade na adolescência.

Influência da mídia em universitárias brasileiras de diferentes regiões

A mídia tem impacto na satisfação com a imagem corporal e risco para o desenvolvimento de transtornos alimentares. OBJETIVO: Avaliar a influência da mídia em universitárias e possíveis associações com idade, estado nutricional, renda e escolaridade do chefe da família. MÉTODOS: 2.489 estudantes do sexo feminino das cinco regiões do Brasil responderam à Sociocultural Attitudes Towards Appearance Scale (SATAQ-3). O escore na SATAQ foi comparado entre as regiões por meio de uma análise de variância. Uma análise de covariância foi utilizada para verificar a influência das variáveis estudadas no escore da SATAQ. Uma regressão logística foi realizada para verificar a interferência conjunta das variáveis em relação à influência da mídia. RESULTADOS: Não foram encontradas diferenças regionais na SATAQ total (p = 0,164) e subescalas Internalização atlética (p = 0,293) e Pressão (p = 0,150); houve diferença para as subescalas Internalização geral (p = 0,010) e Informação (p = 0,002). Idade, estado nutricional e renda influenciaram o resultado. CONCLUSÕES: O escore total na SATAQ foi similar entre as regiões, mas o Sul e o Nordeste apresentaram maiores pontuações para subescalas Internalização geral e Informação respectivamente. Estudantes com menos de 25 anos, com excesso de peso e maior renda foram em média mais influenciadas pela mídia.

Atenção farmacêutica em farmácias e drogarias: existe um processo de mudança?

Para se conhecer a prática profissional de farmacêuticos que atuam em farmácias e drogarias, seus conhecimentos e percepções acerca da Atenção Farmacêutica (AF), realizou-se estudo descritivo com 91 farmacêuticos do município de Jundiaí-SP. A maioria era jovem (62,6% entre 20 e 29 anos), do sexo feminino (63,7%), graduada em instituições privadas (90,1%) e não proprietária do estabelecimento (87,9%). Desenvolviam atividades administrativas, técnicas e de atenção ao usuário, principalmente dispensação de medicamentos e orientação; 67,0% acompanhavam o tratamento farmacoterapêutico dos usuários, mas sem registrar informações. Para 62,7%, AF relacionava-se apenas à orientação e atendimento dispensados, mas tais atividades não eram realizadas de forma sistemática e organizada, como preconizado. Muitos (91,2%) consideravam necessário realizar trabalho mais intenso com os usuários, porém apontaram dificuldades como falta de tempo e de apoio dos proprietários e desinteresse dos usuários. Várias dessas dificuldades têm sido verificadas também em outros países, sugerindo que a prática da AF: (a) requer uma mudança estrutural e rearranjo de funções, uma vez que, atualmente, a estrutura e as atividades são adequadas à atividade comercial; (b) reflete uma crise de identidade profissional e, em consequência, falta de reconhecimento social e pouca inserção na equipe multiprofissional de saúde. O conhecimento sobre AF mostrou-se limitado, mas a situação pode vir a alterar-se à medida que as mudanças curriculares em curso surtam efeito na formação dos novos farmacêuticos.

Epidemiology of leisure, transportation, occupational, and household physical activity: prevalence and associated factors

Background: To estimate the prevalence of and identify factors associated with physical activity in leisure, transportation, occupational, and household settings. Methods: This was a cross-sectional study aimed at investigating living and health conditions among the population of São Paulo, Brazil. Data on 1318 adults aged 18 to 65 years were used. To assess physical activity, the long version of the International Physical Activity Questionnaire was applied. Multivariate analysis was conducted using a hierarchical model. Results: The greatest prevalence of insufficient activity related to transportation (91.7%), followed by leisure (77.5%), occupational (68.9%), and household settings (56.7%). The variables associated with insufficient levels of physical activity in leisure were female sex, older age, low education level, nonwhite skin color, smoking, and self-reported poor health; in occupational settings were female sex, white skin color, high education level, self-reported poor health, nonsmoking, and obesity; in transportation settings were female sex; and in household settings, with male sex, separated, or widowed status and high education level. Conclusion: Physical activity in transportation and leisure settings should be encouraged. This study will serve as a reference point in monitoring different types of physical activities and implementing public physical activity policies in developing countries

Insatisfação com a imagem corporal em universitárias brasileiras

A insatisfação com a imagem corporal é avaliada por meio da diferença entre a figura real e a idealizada e pode influenciar comportamentos alimentares. OBJETIVO: Avaliar a insatisfação corporal de universitárias do sexo feminino nas cinco regiões do país e possíveis associações e correlações com a idade, o estado nutricional, a renda e o grau de escolaridade do chefe da família. MÉTODOS: 2.402 universitárias responderam à Escala de Silhuetas de Stunkard. As regiões foram comparadas por meio da análise de variância; correlações entre as variáveis foram analisadas pelos coeficientes de Pearson e Spearman. RESULTADOS: 64,4 por cento gostariam de ser menores do que sua figura atual, e mesmo as estudantes eutróficas escolheram figuras saudável e ideal menores. Na região Norte foram apontados os mais magros padrões ideais e de saúde e na região Centro-Oeste, os maiores. CONCLUSÃO: A ocorrência de insatisfação corporal foi bastante expressiva, com algumas diferenças regionais e sociodemográficas que devem ser consideradas

OFFSPRING IN RESPONSE TO PARENTAL FEMALE DENSITIES IN THE FRUIT FLY PARASITOID DIACHASMIMORPHA LONGICAUDATA (HYMENOPTERA: BRACONIDAE: OPIINAE)

As part of an evaluation of the braconid parasitoid Diachasmimorpha longicaudata (Ashmead) as a biocontrol agent of Ceratitis capitata (Wiedemann) in Brazil, the aims in the current study were to find the best parental ratio of females to males in the rearing cages in order to get the highest female biased offspring in the parasitoid rearing process, and to verify the parasitism efficiency on C. capitata according to parental female densities. Three treatments were assessed: T1 (20 females: 20 males), T2 (60 females: 20 males) and T3 (100 females: 20 males). Ten late-third instars of C. capitata were offered daily to each female parasitoid from the 1st to the 12th d of age. The parental female productivity, fecundity, offspring sex ratio, percentage of parasitoid emergence, and daily mortality of parental females and males at different female/male densities were evaluated. The results indicated that numbers higher than 20 parental females did not affect offspring sex ratio, overall offspring production, nor the percent parasitism. Female biased offspring occurred in all three parental female/male ratios analyzed in this study, except that predominately males developed from parasitoid eggs laid in the age interval 1-2 d post emergence. Higher parasitoid female productivity and fecundity were found at the 1:1 female/male per cage density whereas lower productivity and fecundity were recorded at the 5:1 female/male ratio. Higher female/male ratio in the parental cages increased the mortality rate of females but did not influence the number of parental male deaths. The results may facilitate advancement of an optimum mass-rearing system to aid in control of C. capitata in Brazil.
