Estudo multicêntrico Brasileiro - Adesivo contraceptivo transdérmico semanal: Preferência e satisfação das usuárias

Background: To assess satisfaction with the weekly transdermal contraceptive patch, compared to the previous contraceptive method. Adhesion, cycle control, safety and efficacy were secondary outcomes. Methods: A multicenter, open label, descriptive study. Subjects received the weekly transdermal contraceptive patch for 6 cycles. At the baseline and after the 1 st, 3 rd and 6 th cycles, satisfaction with the method was assessed. The contraceptive efficacy was assessed by the Pearl Index and by life table analysis. Results: An ITT analysis was performed with 494 subjects. At the endpoint, 95.3% of women were satisfied with the patch compared to the previous method; 59.5%, 58.0% and 63.2% of women reported improvement in the physical and emotional well-being, and pre-menstrual symptoms, respectively. Pre-menstrual symptoms frequency decreased from 85.0% (CI 95%: 80.8-87.4%) to 55.0% (CI 95%: 49.9-66.0%). There was a significant increase in hemoglobin levels, and also a significant decrease in total serum cholesterol and tryglicerides.. There were no significant adverse events. The adjusted Pearl Index was 1.1 pregnancies per 100 women-years. Conclusions: The weekly contraceptive transdermal patch is a safe and effective method, and there was a high rate of satisfaction with its use among brazilian women. The patch was associated to a good cycle control, with easiness of use, improvement in the physical and emotional well-being and improvement in the premenstrual symptoms and lipid profile. © Copyright Moreira Jr. Editora.

Intervenções farmacêuticas na atenção à saúde mental: Uma revisão

Uma revisão dirigida foi realizada nas bases de dados IBECS, LILACS e MEDLINE, até fevereiro/2011, para identificar intervenções farmacêuticas (IF) na atenção farmacêutica em saúde mental e os seus resultados. Para a busca utilizaram-se os descritores em saúde: Pharmaceutical Care, Pharmaceutical Services, Medication Adherence, Pharmacists, Mental Health, Mental Health Services, Mental Health Assistance, Community Mental Health Services, Mentally Ill Persons andMental Disorders. Identificaram-se 1686 publicações, das quais 21 contemplaram os critérios de inclusão. Após exploração do material, apenas cinco estudos tratavam-se de IF. Todos foram conduzidos no nível secundário de atenção, com abordagem individual, por meio do acompanhamento da terapia (3), intervenção educativa por cartas a médicos e pacientes (1), aconselhamento farmacêutico presencial e remoto e inserção de terapia com sistema transdérmico de nicotina (1). Os resultados, tais como promoção da adesão e resolução de problemas relacionados a medicamentos foram positivos para a terapêutica. No entanto, é necessário que as IF monitorem os parâmetros clínicos, as mudanças de hábitos, a melhora na qualidade de vida e os aspectos farmacoeconômicos a fim de avaliar os seus impactos.

ABSTRACT Pharmaceutical interventions in mental health services: a review A directed review was performed in IBECS, LILACS and MEDLINE databases, until February/2011, in order to identify the studies which developed pharmaceutical interventions (PI) in pharmaceutical care in mental health services and estimated their results. The search was carried out using the follow health science descriptors: Pharmaceutical Care, Pharmaceutical Services, Medication Adherence, Pharmacists, Mental Health, Mental Health Services, Mental Health Assistance, Community Mental Health Services, Mentally Ill Persons andMental Disorders. It was identified 1686 manuscripts, of whose 21 contemplated the inclusion criteria. After the content analysis of the eligible manuscripts, only five developed PI. All of them were conducted in the second level of health care, with individual approach, through: therapy follow-up (3), educational interventions by letters to physicians and patients (1), presence or remote pharmaceutical counseling and inclusion of therapy with nicotine transdermal patch (1). The data, such as adherence promotion and solving drug related problems, were positive for the therapeutic. However, it is necessary that the PI monitor the clinical parameters, the habit changes, the improvement in the quality of life and the pharmacoeconomic aspects, in order to assess their impacts. Keywords: Pharmaceutical Care. Pharmaceutical Services. Medication Adherence. Pharmacists. Mental Health. Mental Disorders.

Stochastic dynamics in exotic and native blowflies: an analysis combining laboratory experiments and a two-patch metapopulation model

In this study we explored the stochastic population dynamics of three exotic blowfly species, Chrysomya albiceps, Chrysomya megacephala and Chrysomya putoria, and two native species, Cochliomyia macellaria and Lucilia eximia, by combining a density-dependent growth model with a two-patch metapopulation model. Stochastic fecundity, survival and migration were investigated by permitting random variations between predetermined demographic boundary values based on experimental data. Lucilia eximia and Chrysomya albiceps were the species most susceptible to the risk of local extinction. Cochliomyia macellaria, C. megacephala and C. putoria exhibited lower risks of extinction when compared to the other species. The simultaneous analysis of stochastic fecundity and survival revealed an increase in the extinction risk for all species. When stochastic fecundity, survival and migration were simulated together, the coupled populations were synchronized in the five species. These results are discussed, emphasizing biological invasion and interspecific interaction dynamics.

Patch-size and isolation effects in the Fisher-Kolmogorov equation

We examine the classical problem of the existence of a threshold size for a patch to allow for survival of a given population in the case where the patch is not completely isolated. The surrounding habitat matrix is characterized by a non-zero carrying capacity. We show that a critical patch size cannot be strictly defined in this case. We also obtain the saturation density in such a patch as a function of the size of the patch and the relative carrying capacity of the outer region. We argue that this relative carrying capacity is a measure of the isolation of the patch. Our results are then compared with conclusions drawn from observations of the population dynamics of understorey birds in fragments of the Amazonian forest and shown to qualitatively agree with them, offering an explanation for the importance of dispersal and isolation in these observations. Finally, we show that a generalized critical patch size can be introduced resorting to threshold densities for the observation of a given species.

Population variation in patch and party size in muriquis (Brachyteles arachnoides)

We examined the relationship between food patch size and feeding party size with comparative data from two populations of muriquis (Brachyteles arachnoides) in the 37,797-ha forest at the Parque Estadual de Carlos Botelho (PECB), São Paulo, and the 800-ha forest at the Estacao Biologica de Caratinga (EBC), Minas Gerais. Precipitation Mins more abundant and less seasonal at PECB than EBC, and the density of large trees (>25.0 cm) was higher at PECB (206 ha(-1)) than at EBC (132 ha(-1)). At both sites, the size of feeding parties is positively related to the size of food patches, As predicted, food parches at PECB are significantly larger than those at EBC for both fruit and leaf sources. Contrary to expectations, feeding parties were larger at EEC than PECB, the higher population density of muriquis and sympatric primates at EBC may make large associations more advantageous to these muriquis than to muriquis living at lower population densities in PECB.

Continuous Electrical Current and Zinc Sulphate Administered by Transdermal Iontophoresis Improves Skin Healing in Diabetic Rats Induced by Alloxan: Morphological and Ultrastructural Analysis

Purpose. Evaluated the effects of continuous electrical current (CEC) or zinc administrated by transdermal iontophoresis (Zn+TDI). Methods. 120 male Wistar rats were submitted to an incision surgery at the anterior region of abdomen and distributed into 6 experimental groups with 40 animals: 3 diabetic groups and 3 normal groups, untreated and treated with CEC alone or with Zn+TDI. Each group was further divided into 4 subgroups with 10 rats each to be evaluated on the 4th, 7th, 14th, and 21st day after surgery. In each period, clinical and laboratory parameters from the animals were analyzed. Results. The analysis by optical and scanning electron microscopy showed a delay in the phases of wound healing in diabetic rats without treatment in all periods of the experiment; breaking strength (BS) was significantly reduced in skin scars of untreated diabetic rats when compared to other groups. In contrast, BS in skin scars of nondiabetic groups and diabetic rats treated with Zn+TDI showed significant increase in those, besides not presenting delayed healing. Conclusion. Electrical stimulation of surgical wounds used alone or in association with zinc by TDI is able to consistently improve the morphological and ultrastructural changes observed in the healing of diabetic animals.
