Praziquantel, levamisol e diflubenzuron no controle de Dolops carvalhoi (Crustacea: Branchiura) e Anacanthorus penilabiatus (Monogenea: Dactylogyridae) em Piaractus mesopotamicus Holmberg, 1887 (Osteichthyes: Characidae)

Neste trabalho, avaliou-se a eficácia antiparasitária do praziquantel, levamisol e diflubenzuron administrados via oral, adicionados à ração, para pacus (Piaractus mesopotamicus) infectados por Anacanthorus penilabiatus e Dolops carvalhoi. Foram utilizadas 19 caixas d'água de 300 L de capacidade, comportando 28 peixes cada. Os tratamentos foram feitos misturando os princípios ativos nas dietas. A intensidade parasitária e eficácia foram avaliadas 1 dia antes e 3, 7 e 15 dias após o início da alimentação com ração contendo diflubenzuron, levamisol e praziquantel isolados ou associados em diferentes concentrações por 7 dias. Os resultados da eficácia terapêutica sugerem que, isoladamente ou associado com levamisol e praziquantel, o diflubenzuron é eficiente contra o crustáceo D. carvalhoi, demonstrando que a eficácia dos tratamentos nos dias 3, 7 e 15 variou de 96,2 a 100%. Contra os monogenóides, as drogas não apresentaram eficácia satisfatória. Os resultados sugerem o uso do diflubenzuron para o controle de D. cavalhoi em peixes de cativeiro e em condições de quarentenário.

Participation of α2 -adrenoceptors in sodium appetite inhibition during sickness behaviour following administration of lipopolysaccharide

Sickness behaviour, a syndrome characterized by a general reduction in animal activity, is part of the active-phase response to fight infection. Lipopolysaccharide (LPS), an effective endotoxin to model sickness behaviour, reduces thirst and sodium excretion, and increases neurohypophysial secretion. Here we review the effects of LPS on thirst and sodium appetite. Altered renal function and hydromineral fluid intake in response to LPS occur in the context of behavioural reorganization, which manifests itself as part of the syndrome. Recent data show that, in addition to its classical effect on thirst, non-septic doses of LPS injected intraperitoneally produce a preferential inhibition of intracellular thirst versus extracellular thirst. Moreover, LPS also reduced hypertonic NaCl intake in sodium-depleted rats that entered a sodium appetite test. Antagonism of α2 -adrenoceptors abolished the effect of LPS on sodium appetite. LPS and cytokine transduction potentially recruit brain noradrenaline and α2 -adrenoceptors to control sodium appetite and sickness behaviour.

Sepsis and AKI in clinical emergency room patients: the role of urinary NGAL

Few studies have investigated the predictive properties of urinary (u) NGAL as an AKI marker in septic population. This study evaluated the efficacy of uNGAL as predictor of AKI and death in septic patients admitted to the clinical emergency room (ER). We prospectively studied patients with sepsis admitted to the ER. Urine was analyzed for NGAL within the first 24 hours after admission (classified as NGAL1), between 24 and 48 h (NGAL2), and at moment of AKI diagnosis (NGAL3). Among 168 septic patients admitted to ER, 72% developed AKI. The uNGAL and its relationship with creatinine (Cr) were high in septic patients but statistically higher in those with sepsis and AKI. The uNGAL1 and uNGAL2, as well as uNGAL1/uCr1 and uNGAL2/uCr2, were good predictors for AKI (AUC-ROC 0.73, 0.70, 0.77, and 0.84, resp.). The uNGAL1 and uNGAL1/uCr1 were poor predictors for death (AUC-ROC 0.66 and 0.68, resp.), whereas uNGAL2 and uNGAL2/uCr2 were better predictors (AUC-ROC 0.70 and 0.81, resp.). The uNGAL is highly sensitive but nonspecific predictor of AKI and death in septic patients admitted into ER.

Capacitação de produtores rurais para a melhoria da qualidade do leite cru produzido na região de Araçatuba - SP

This paper reports the results of an extension project carried out at Unesp/Veterinary Medicine course in Araçatuba city with milk farmers of the region. The aim of the project was to supply information to farmers concerning to good quality milk production and, at the same time, to follow up the evolution of milk quality parameters, according to the current Brazilian legislation. Every 45 days, approximately, lectures were presented to milk farmers in Araçatuba city region, approaching chemical and microbiological composition of milk, prevention and detection of mastitis, hygiene proceedings in milking and conservation of milk, cleaning and sanitization operations of facilities and equipments and prevention of adulteration. During the intervals between lectures, milk samples were collected from collective milk cooling tanks and analyzed for microbiological, hygienic and physicochemical tests. The main inadequacies in milk quality were high total bacteria and somatic cells counts, low solids contents and water addition. These problems did not proceed to betterment during the project time. So, it was concluded that the time for instruction of farmers was not enough for a progress in the quality of the milk produced in the region, pointing out the need in continuing this kind of work.

Microbiota asociated with infections of the jaws

The microbial infections involving the craniofacial skeleton, particularly maxilla and mandible, have direct relationship with the dental biofilm, with predominance of obligate anaerobes. In some patients, these infections may spread to bone marrow or facial soft tissues, producing severe and life-threatening septic conditions. In such cases, local treatment associated with systemic antimicrobials should be used in order to eradicate the sources of contamination. This paper discuss the possibility of spread of these infections and their clinical implications for dentistry, as well as their etiology and aspects related to microbial virulence and pathogenesis.
