Effect of a spray formulation on the reproductive parameters of a susceptible population of Rhipicephalus (Boophilus) microplus

The number of studies emphasizing the possible damage that acaricidal spray formulations can cause on engorged female ticks'reproductive parameters is small. The present study evaluated the deleterious effects of a spray formulation (dichlorvos 60% + chlorpyrifos 20%) on the reproductive parameters of a susceptible population of Rhipicephalus (B.) microplus females, using the Stall Test. The ticks were allocated randomly to treatments according to the mean numbers of females detached from each cow on days -3, -2 and -1 and the cattle pen location. The numbers of engorged female ticks that naturally detached from the cattle were counted daily from day 1 to day 30. For each group, 20 detached engorged female ticks or the available number collected daily were evaluated regarding reproductive parameters. Associations of organophosphates demonstrated elevated acaricidal efficacy, as well as deleterious effects on the reproductive parameters of R. (B.) microplus females. The engorged female weight (days 1 to 7), weight of egg masses (days 5 to 10) and larval hatching percentage (days 5 to 19) were decreased (P <= 0.05). It is possible that a formulation can lead to deleterious effects on R. (B.) microplus females when the tick population analyzed shows elevated sensitivity towards a particular formulation. However, further studies need to be conducted.

Endoparasites of horses from the Formiga city, located in center-west region of the state of Minas Gerais, Brazil

With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

Anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 mu g/kg/day), against nematodes in naturally infected pigs

The present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the EPG (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by 'parasitological necropsies. The animals were randomly selected based on the average of three consecutive EPG counts of Strongylida, Ascaris suum and Trichuris for experiment I, and of Strongylida and Trichuris for experiment II. After the random draw, eight animals were treated, orally, during seven consecutive days with 100 mu g/kg/day ivermectin (Ivermectina (R) premix, Ouro Fino Agronegocios), eight other animals were treated, orally, during seven consecutive days with 100 mu g/kg/clay abamectin (Virbamax (R) premix - Virbac do Brasil Industria e Comercio Ltda.), and eight pigs were kept as controls. EPG counts were performed for each individual animal at 14th day post-treatment (DPT). All animals (control and treatment) were necropsied at the 14th DPT. The results from both experiments demonstrate that both ivermectin and abamectin, administered orally for a continuous period of seven days, at a daily dosage of 100 mu g/kg, were highly effective (>95%) against Hyostrongylus rubidus, Strongyloides ransomi, Ascaris suum and Metastrongylus salmi. Against Oesophagostomum dentatum, abamectin presented over 95% efficacy against both evaluated strains, while ivermectin reached other strain as resistant. Regarding T. suis, both ivermectin and abamectin were effective (efficacies >90%) against one of the tested strains, while the other one was classified as resistant. Furthermore, the EPG values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. (C) 2014 Elsevier Ltd. All rights reserved.

Cumulative long-term safety, efficacy and patient-reported outcomes in children with juvenile idiopathic arthritis treated with intravenous abatacept: up to 7 years of treatment

The long-term efficacy and safety of intravenous abatacept in patients (pts) with juvenile idiopathic arthritis (JIA) have been reported previously from the Phase III AWAKEN trial ([1, 2]). Here, we report efficacy, safety and pt-reported outcomes from the open-label, long-term extension (LTE) of AWAKEN, with up to 7 years of follow-up. Pts entered the LTE if they were JIA ACR 30 non-responders (NR) at the end of the 4-month lead-in period (abatacept only), or if they received abatacept or placebo (pbo) in the 6-month double-blind (DB) period. The Child Health Questionnaire was used to evaluate health-related quality of life (HRQoL); physical (PhS) and psychosocial (PsS) summary and pain scores were analyzed. Pain was assessed by parent global assessment using a 100 mm visual analog scale. Efficacy and HRQoL evaluations are reported up to Day 1765 (~ Year 5.5). Safety is presented for the cumulative period (lead-in, DB and LTE), for all pts who received abatacept during the LTE. Of the 153 pts entering the LTE (58 from DB abatacept group, 59 from DB pbo group, 36 NR), 69 completed the trial (29 abatacept, 27 pbo, 13 NR). For pts treated in the LTE, mean (range) exposure to abatacept was 53.6 (5.6–85.6) months. During the LTE, incidence rates of AEs and serious AEs per 100 pt-years were 209.1 and 5.6. Thirty pts (19.6%) had serious AEs; most were unrelated and were musculoskeletal (8.5%) or infectious events (6.5%). No malignancy was reported. There was one death (accidental; unrelated). At Day 169, JIA ACR 50 and 70 response rates were 79.3% and 55.2% in the abatacept group, and 52.5% and 30.5% in the pbo group; 31.0% and 10.2% of pts in the abatacept and pbo groups, respectively, had inactive disease. By Day 1765, JIA ACR 50 and 70 response rates were 93.9% and 78.8% in the abatacept group, and 80.0% and 63.3% in the pbo group; 51.5% and 33.3% had inactive disease. In the NR group, 69.2% and 53.8% of pts achieved JIA ACR 50 and 70 responses at Day 1765, and 30.8% had inactive disease. In pts who entered the LTE, mean baseline PhS scores were below the range for healthy children (abatacept 30.2, pbo 31.0, NR 29.5). At Day 169, 38.3% of pts had reached a PhS score >50 ((1). By the end of the LTE, 43.5% of pts had reached a PhS score >50. At baseline, mean PsS scores for those who entered the LTE were slightly lower than the mean for healthy children (abatacept 43.5, pbo 44.2, NR 47.0). At Day 169, 54.9% of pts had a PsS score >50 (1). By Day 1765, 58.1% of pts had reached a PsS score >50. At baseline, the mean pain score was 42.9. By Day 169, 13.9% of pts were considered pain free (pain score = 0); this was maintained over the LTE (1).

Avaliação da aplicação exógena de poliaminas no crescimento de calos de mangabeira (Hancornia speciosa Gomes)

Este trabalho teve como objetivo estudar o efeito das poliaminas espermidina e espermina no crescimento de calos Hancornia speciosa Gomes. Calos com 0,5 cm de diâmetro foram inoculados em meio Murashige & Skoog (1962) (MS) a 50% + 100 mg L-1 de caseína hidrolisada + 200 mg L-1 de levedura de cerveja, variando os tratamentos:A: 1 mmol de espermina + 2 mg L-1 de 2,4-D (ácido 2,4 diclorofenoxiacético) + 0,5 mg L-1 de NAA (ácido naftalenoacético); B: 1 mmol de espermidina + 2 mg L-1 de 2,4-D + 0,5 mg L-1 de NAA; C: 2 mg L-1 de 2,4-D + 0,5 mg L-1 de NAA. Não houve influência das poliaminas no crescimento dos calos. observou-se, nos calos tratados com espermidina, maior concentração celular de putrescina (582,37 µg g mf-1) aos 60 dias, maior teor de espermidina (502,54 µg g mf-1) e espermina (868,53 µg g mf-1) aos 40 dias de cultivo, quando se aplicou a própria poliamina. Conclui-se que a aplicação exógena de poliaminas em Hancornia speciosa não proporciona aumento no crescimento de calos. A oxidação promovida por longos períodos de cultivo in vitro induz aumento nos níveis de putrescina.

Susceptibility of helminth species from horses against different chemical compounds in Brazil

By means of parasitological necropsies, the present study aimed to evaluate, in six experiments, the degree of susceptibility or resistance of different helminth species which naturally infect horses to ivermectin 0.2mg/kg, abamectin 0.2mg/kg, moxidectin 0.4mg/kg, trichlorfon 35mg/kg, ivermectin 0.2mg/kg+praziquantel 2.5mg/kg, abamectin 0.2mg/kg+praziquantel 2.5mg/kg and ivermectin 0.2mg/kg+6.6 mg/kg pyrantel. At experimental day zero, the horses were allocated to treatment groups based on average counts of strongylid eggs per gram of feces (EPG) obtained on days -3, -2 and -1. Oxyuris sp. infections were confirmed as positive or negative. All the animals in the six experiments were naturally infected by this helminth species. Each group (control or treated) consisted of six animals. All the assessed Habronema muscae populations analyzed were susceptible to ivermectin, abamectin and moxidectin. Of the six Trichostrongylus axei populations, four were susceptible to ivermectin, abamectin, moxidectin, trichlorfon and ivermectin+praziquantel, and two were resistant to abamectin+praziquantel and ivermectin+pyrantel. Both Strongyloides westeri populations analyzed were susceptible to ivermectin, abamectin, moxidectin and abamectin+praziquantel. For O. equi, resistance was found in four different populations treated with ivermectin, abamectin, moxidectin, trichlorfon and ivermectin+praziquantel. Only combinations of abamectin+praziquantel and ivermectin+pyrantel were effective against this parasite species. All the large strongyles diagnosed in the present study (Strongyus edentatus, Strongyus vulgaris and Triodontophorus serratus) were susceptible to all the chemicals tested, with the exception of trichlorfon. Of the Cyathostominae populations, one was diagnosed as resistant to ivermectin and another to trichlorfon. The remaining populations from this nematode group were considered to be sensitive to ivermectin, abamectin, moxidectin, ivermectin+praziquantel, abamectin+praziquantel and ivermectin+pyrantel. New studies should be performed in different regions to evaluate the efficacy of trichlorfon in others field populations of helminthes.

Effects of different spray formulations on the reproductive parameters of engorged Rhipicephalus (Boophilus) microplus females detached from experimentally infested cattle

This present study aimed to evaluate the deleterious effects of some commercially available spray formulations (15% Cypermethrin+25% Chlorpyriphos+1% Citronellal and 8% Cypermethrin+60% Ethion) on the reproductive parameters of engorged Rhipicephalus (Boophilus) microplus females that detached from experimentally infested cattle. The following reproductive parameters of engorged female ticks were analyzed: female weight, egg mass weight, percentage of hatchability, percentage of reduction in oviposition, percentage of reduction in hatchability, reproductive efficiency and percent control/efficacy of formulations for reproductive parameters. Our findings showed that although the strain R. (B.) microplus used in both experiments was thought to be sensitive to the test compounds because of the acaricidal efficacy observed throughout these trials, it was not possible to observe overall deleterious effects on the reproductive parameters of this tick species with both spray formulations. However, the 8% Cypermethrin+60% Ethion showed short-term significant effects on the weight of female ticks between the 14th and 16th days post-treatment and the weight of female and the egg mass weight between the 20th and 22nd days post-treatment. New studies should be conducted to show if these results regarding the reproductive parameters of fully engorged R. (B.) microplus females, combined with the acaricidal efficacy can be sufficient to reduce the number of chemical treatments administered to cattle.

Nível de satisfação dos pacientes edêntulos reabilitados com prótese total na faculdade de odontologia de Adamantina FAI

The population’s life expectancy is growing every year. This fact highlights the importance of the elderly for the dentistry. The oral cavity quality has great influence on quality of life at both the biological and the psychological and social factors by maintaining a self-esteem, self-expression, communication and satisfactory facial aesthetics. Unfortunately, the number of edentulous elderly population is also high, which may create problems to their social life. Therefore, the objective of this study was to demonstrate and evaluate the difficulties of treating edentulous patients, comparing data prior to treatment to post data after treatment by complete dentures made to the patients undergoing oral rehabilitation in the Dental Clinic of the Faculty of Dentistry of Adamantina – FAI. For this study, questionnaires were filled in the form of answers developed alternative focused on the degree of patient satisfaction, the current situation of occlusion, and outcome of treatment. The results showed that 96% of patients were satisfied with the results obtained in the treatment, all of whom believed that the prosthesis helped them feel better aesthetically and improved self-esteem. By this methodology, it was concluded that the degree of satisfaction was high, but the services provided must be constantly reevaluated, once the elderly population presents a wide labor market for dental professionals and demand level services will certainly increase each year.
