Malaria is an infectious disease endemic in 104 countries and vivax malaria accept responsibility for 25 to 40% of the global burden of disease worldwide. The South America has high transmission rates shown by the annual parasite incidence (API) greater than 1% of the population. In recent years it has been observed in Brazil the prevalence of infection with P. vivax. The treatment protocol isased on the combination of chloroquine and primaquine, however, treatment failures have been reported worldwide including in Brazil with adherence as one of the causes. Several factors can interfere in the adherence between them: education, sex, absence of signs and symptoms and socioeconomic profile. This study evaluated the adherence to malaria treatment from determining the profile demographic partner of children with vivax malaria in Anajás and determined the plasma concentrations of chloroquine and primaquine of the study patients. For the profile of the participants was used questionnaire was complete source of information. To measure adherence to treatment was used indirect test Morisky-Green assessing the patient's attitude towards treatment. The plasma concentration of primaquine and its metabolite was made by collecting paper filter venous blood on day D1 and D7 and determined HPLC. The profile of patients showed that most of the children were male, with the primary caregiver mother, education and income were considered low, despite the distribution the use of mosquito nets it is irregular, 92.4% of households have no sewage system, and 33.3% use water from the river for consumption .The indirect test Morisky- Green classified 42 children as adherent and 08 as no adherent The plasma concentration of PQ in D7 adherent and no adherent were related and showed no significant difference, since the CPQ concentrations in D7 Adherent showed statistically significant result, with higher values in adherent patients.

The study of medicinal plants raised great scientific interest, mainly due to them being considered as potential sources of bioactive molecules with differentiated structure and new mechanism of action. The importance of research focused on the discovery and production of new herbal medicines should be the great contribution they have presented before diverse pathologies. The species Petiveria alliacea is a medicinal plant widely used by the population of the Amazon region and stands out for presenting various claims and still use some classes of metabolites with proven therapeutic actions. This study aimed to evaluate seasonal pharmacognostical parameters, antifungal potential of the extracts produced at different sampling times on Aspergillus species and toxicity of these in vitro and in vivo. In the evaluation of seasonal Pharmacognostical, P. alliacea, using Brazilian Pharmacopeia methods the results demonstrated reproducible parameters for quality control of the plant drug, there was no difference in the presence of the chemical constituents of hydroalcoholic and dust, revealing the presence of saponins, alkaloids and sugars across the plant and root extracts and only sesquiterpenolactones depsides. The results of microdilution method performed with extracts from the roots of two periods, showed weak antifungal activity in vitro, but did not observe any effect of extracts of the aerial parts. The cytotoxicity was evaluated by MTT colorimetric method, showed that the hydroalcoholic extract of the root of the two periods did not reduce cell viability in any of the concentrations tested, and was any signs of acute toxicity of the extract at a dose of 5000 mg/kg in mice. These data are considered relevant and the current study showed that P. alliacea is a promising medicinal species, but further investigations are required for its various allegations are confirmed and usage for the plant to be used in developing a new phytotherapeutic agent.

Adherence to pharmacotherapy in several chronic diseases, especially hypertension (SH), has great importance for the prevention, reduction and control of diseases and complications, thus reducing cardiovascular morbidity and mortality. Evaluate the modifiable and non-modifiable factors that contribute to a better adherence to medication in patients DAGUA district in Belém-PA, can serve as the basis for qualification of pharmaceutical care, clinical management, public politics, actions and plans in services public health in order to improve patient compliance. We conducted a descriptive transversal observational and quantitative analysis with a random sample of 227 patients enrolled in the program HIPERDIA, from March 2010 to August 2011, where we assessed the knowledge and the degree of adherence to drug therapy using the tests Morisky and Green (TMG) and the Batalla test relating to socioeconomic, lifestyle, and esquipe health service and patient-related factors. The study population was characterized predominantly by women (69.5%) aged above 60 years (44.5%), mixed race (48%), married (44.9%), retired (43.6%) and with low educational level, being (55.1%) with incomplete primary education. Of the total persons (63.46%) had uncontrolled blood pressure. Not adhere to treatment (66.9%) according to test Morisky and Green (72.38%) by the test Batalla.

(Universidade Federal do Pará, 2017) FEITOSA, Keith Brabo Tavares; MARTINS, Valéria de Carvalho; http://lattes.cnpq.br/1904927472781784; ANDRADE, Marcieni Ataíde de; http://lattes.cnpq.br/8514584872100128
Cystic Fibrosis is an inherited disease, clinically manifested by digestive and respiratory symptoms. The early diagnosis offers the possibility of a better therapeutic control of the disease’s symptoms in favor of the prognosis and contributing to increasing quality of life. The aim of this study was to demonstrate the patient's behavior towards the disease and to evaluate the adherence to the treatment with the alfadornase enzyme. A cross-sectional study was carried out using epidemiological data collected through direct interviews with patients and/or their caregivers and by medical records analysis. Morisky-Green and Batalla Martinez tests were employed in order to evaluate the patient’s adhesion and knowledge of the disease, respectively. In addition, the clinical profile was assayed by Shwachman-Kulczyki score. Fifty-one (51) patients with cystic fibrosis in treatment with alfadornase were recruited at the outpatient clinic of the Hospital Universitário João de Barros Barreto. At final, forty-seven (47) patients participated in the study. Most of the patients (53.2%) were under 18 years of age, male (56.6%) and were from countryside (40.4%). Patients with long term use of alfadornase (> 5 years) show possess greater adherence than the others with a shorter treatment period. The male sex was associated with higher adherence, as well as greater education level and family income. The Batalla Martinez test demonstrates that only 40.42% of patients had some knowledgement about their disease. Thus, the factors associated with low adherence were: use of more than five medications, low education and gender. On the other way, these results shows that adherence to the medication was associated with the best clinical score.

Avaliação da adesão ao tratamento preconizado para malária: determinação da primaquina em pacientes diagnosticados com Plasmodium vivax
(Universidade Federal do Pará, 2016-03-31) GONÇALVES FILHO, Wilson Vieira; VIEIRA, José Luiz Fernandes; http://lattes.cnpq.br/2739079559531098; ANDRADE, Marcieni Ataíde de; http://lattes.cnpq.br/8514584872100128
Malaria is a disease that threatens 50% of the world population living in endemic areas such as Africa, Asia and Latin America. Concerning malaria caused by Plasmodium vivax in Brazil, which treatment is based on primaquine and chloroquine, it is a major public health issue that hinders the development of the Amazon region and adherence to drug therapy is one of the main factors that influence the effectiveness of the drug. This study uses indirect methods assess treatment adherence, correlating it with plasma concentrations of primaquine and carboxyprimaquine. Thus, a cross-sectional observational controlled study was conducted with 27 patients in Anajás, Pará before (D0), during (D1) and after (D7) treatment using the antimalarials, followed by the assessment of the patients with questions based on Morisky-Green test at the end of the treatment. Higher prevalence of vivax malaria was observed in males (70.4%) and age group of 20-39 years (55.56%), Morisky-Green test indicated adherence of 75%, 15 out of 20 patients, with hit rates of 80%, 65%, 70% and 65% to the questions. Mean-value of primaquine concentration on D1 was 134.8 ng/mL, and 131.9 ng/mL on D7, values for carboxyprimaquine are 408 ng/ml and 529.4 ng/mL respectively. It is possible to observe a statistically significant difference in the carboxyprimaquine values between D1 and D7 in the acceding group defined by the Morisky-Green tests, showing that carboxyprimaquine accumulates in the body; therefore being more suitable for assessing adherence to treatment. Therefore, it is important to point out these concentrations of primaquine and carboxyprimaquine consist as the first determination study of drugs and metabolites found for the short-course treatment suggested by the Ministry of Health for vivax malaria in the Amazon region, supporting the studies of adherence surveys regarding antimalarials.

Wound healing is a complex process that involves the organization of cells, chemical signals and remodeling in order to repair injured tissue. North American statistical data show a prevalence of skin lesions in approximately 22.8% of the world's population. In Brazil, wounds are a serious public health problem. In this sense, the use of medicinal plants as therapeutic agents has aroused interest among researchers due to their most different effects, including healing. Thus, ethnopharmacological studies are found in the literature, which associate the use of A. triplinervis with wound healing, but there is no scientific evidence to prove this activity. Thus, this study aims to evaluate the healing potential of the hydroalcoholic extract of A. triplinervis incorporated in an ointment of 5 and 10%. For that, phytochemical analyzes were carried out: prospecting of the plant drug and the hydroalcoholic extract, by means of colorimetric, precipitation tests, thin layer chromatography and high-performance liquid chromatography of the hydroalcoholic extract. In addition to the macroscopic, morphometric analysis, and histological examination of the hydroalcoholic extract ointment in 5% and 10%, using Dersani® and saline solution, respectively, as positive and negative controls. Through these tests, it was observed that the plant drug presented several compounds: saponins, anthraquinones, steroids and triterpenes, polyphenols and coumarins. For the hydroalcoholic extract the result was similar, but the tests did not indicate the presence of anthraquinones. Analysis by thin layer chromatography of the hydroalcoholic extract revealed positive results for coumarins, steroids and triterpenes. In the chromatographic profile, the extract, obtained by high performance liquid chromatography, showed a peak, being suggestive of coumarin. Macroscopic analysis of the lesions showed that the groups of the 5% and 10% extract ointments had more re-epithelialized wounds. In morphometry there was no statistical difference between the four test groups in the percentage of wound contraction. However, the histological examination showed that the ointment with 10% hydroalcoholic extract showed better quality in the development of tissue repair, as it increased fibroblasts, collagen, keratinization, more than the other groups. Thus, this study showed that A. triplinervis extract ointment did not accelerate the speed of wound closure, however, it did show a beneficial influence on the quality in which the lesions evolved, yet further research is necessary to better understand It is made.

The increase in the elderly population contributes to the higher prevalence of numerous and varied pathologies, whose pharmacological treatments generally include features that lead to the practice of polypharmacy, a factor that has a major impact on the safety of elderly patients, given that polypharmacy is largely responsible for the adverse drug reactions and drug interactions. The objective was to evaluate the safety and use of prescription medications in elderly patients aged 60 years and admitted to the University Hospital João de Barros Barreto, Universidade Federal do Pará. This is a cross-sectional, observational study of descriptive character and exploratory data collection to analysis of medical records was performed, the data were processed using the SPSS 20.0 statistical program. The results showed that the mean age was 71.9 years, 52.7 % women, elderly women showed older than male patients. The hospitalization obtained an average of 21.7 days, average of diagnoses per patient was 2.6. The principal diagnosis of hospitalization was cardiovascular diseases (20.3%). The average number of drugs prescribed per admission was 6.8. The most commonly used drugs were part of the digestive and metabolic system (32.4%), the prevalence of potentially inappropriate prescribing of medications evaluated during hospitalization was 11.2 %, higher among women (58.8%), the potentially inappropriate medication prescriptions was more often in Butylscopolamine (25.2%). In regard to potential drug interactions, were identified in 65.5% of prescriptions, with an average of 8.6 per patient, medication interactions are involved in most of the cardiovascular system (38.6%), most of the interactions potential drug had moderate severity (75.3 %), potential pharmacokinetic interactions of action accounted for 65.4% of prescriptions and hypotension and hyperkalemia together accounted for 30.7% of the RAM , the management strategy was the most frequent monitoring signs and symptoms (65.7%) and with respect to monitoring the blood pressure amounted to 21.8%. In this study, the factors related to polypharmacy were length of hospital stay, number of diagnoses, drug interaction and the amount of inappropriate medications and were seen as a determinant in the occurrence of polypharmacy clinical variables: "number of diagnoses "and" length of stay ". Given these results, there is a need to adopt strategies for the optimization of pharmacotherapy provided to the elderly patient.

(Universidade Federal do Pará, 2012-09-12) PERES, Ana Regina Maués Noronha; MONTEIRO, Marta Chagas; http://lattes.cnpq.br/6710783324317390; ANDRADE, Marcieni Ataíde de; http://lattes.cnpq.br/8514584872100128
Currently, Candidiasis has stood out among fungal infections, due to its high incidence and mortality. In parallel, there is a greater record of microbial resistance and therapeutic failures presented by antifungals available. Chrysobalanus icaco Lin, a species native to the Amazon, has been popularly used in mycoses, without scientific evidence, so the importance of research to evaluate their antifungal properties. The analysis pharmacognostic of leaves of C. icaco indicated levels of loss on drying, total ash and ash insoluble 12.3% ± 0.0288, 4.31% ± 1.67% ± 0.0001 and 0.0012, respectively. Phytochemical screening of the hydroalcoholic extract of the leaves of C.icaco (EHCI) revealed the presence of organic acids, sugars, saponins, catechins, depsídeos, phenols, flavonoids, tannins, proteins, amino acids and purine. In HPLC analysis, it was dominated by the flavonoids, especially Myricetin. Antifungal activity was tested by microdilution opposite strain ATCC 40175 Candida albicans and eleven clinical isolates of oral Candida albicans, C. dubliniensis, C. parapsilosis and C. tropicalis. The MIC ranged from greater than 6.25 mg / mL to 1.5 mg / mL and CFM, when determined, was equal to or greater than 6.25 mg / mL. The EHCI showed moderate activity against the strain ATCC 40175 and the weak antifungal activity against clinical isolates mouth. These results open new perspectives for studies that investigate fractions and substances Chrysobalanus icaco with greater activity against Candida species.

Ayapana triplinervis is an Amazonian plant species, popularly known as japan, which has coumarins as important chemical components, having its presence in relation to their pharmacological effects. Raw extracts of species have shown important antitumor effect. Therefore, this study aimed to isolate an A. triplinervis coumarin to evaluate its antitumor effect on ehrlich ascites tumor. For this, extracts of different polarities were captured from aerial parts of the plant and performed in phytochemical prospecting of plant medicines and extracts used. The best profile extract for coumarins was selected for the relationship by Column Chromatography. The coumarin fraction was subjected to a relationship and an isolated substance was identified by chromatographic methods and spectral. The acute toxicity and antitumor effects of coumarin were evaluated in mice, attracting the evaluation of body weight and cell viability in animals, intraperitoneally with 10, 20 and 40 mg / kg of ayapina. Phytochemical assays showed the presence of saponins, steroids and triterpenes, anthraquinones, polyphenols and coumarins. The ethyl acetate extract was selected for the relationship, without qualifying 28 fractions. As fractions obtaining or better selection profile for coumarins, they were from Fr 12 to 20. As fractions were pooled and refracted for coumarin isolation. Through the analysis it was possible to confirm the isolation of coumarin and identify it as 6,7- (methylenedioxy) coumarin, known as ayapina. Coumarin was considered to have low potential in Mexico. Aiapine showed antitumor effect with intraperitoneal treatment in mice with ascending tumor at doses of 10, 20 and 40mg / kg, by reducing the weight of animals and cancer cells without ascites fluid. Thus, the present study demonstrates for the first time the potential antitumor effect of ayapina.

(Universidade Federal do Pará, 2012) RODRIGUES, Luiz Mário Pará; SILVA, Marcos Valério Santos da; http://lattes.cnpq.br/0379783635000306; ANDRADE, Marcieni Ataíde de; http://lattes.cnpq.br/8514584872100128
The Hypertension is a condition associated with high morbidity and mortality with low control rates, one of the most important public health problems in the world. This is a descriptive exploratory study of cross-sectional and observational nature, conducted in five health units DAGUA Administrative District, located in the city of Belém, in the period between March 2010 and August 2011. Research also conducted a study where information was transcribed document, for forms of research. This study sought to ascertain the logistics supply and usage profile of drugs to control blood pressure in administrative district DAGUA. Therefore, we investigated the sociodemographic profile of program participants HIPERDIA, what medications provided by the municipal health for the treatment of hypertension, as well as the logistics employed by the municipality to access to them. The study population was characterized as mostly elderly, with low education and predominantly made up of browns. It was observed that 53.78% of patients makes use of monotherapy and 46.22% polytherapy. Captopril uses only 36.84%. 65.31% of patients who polytherapy using the combination of captopril and hydrochlorothiazide. There was no significant correlation between the socioeconomic aspects of the participants and the control of blood pressure levels. Knowledge about hypertension did not influence the results of the PA. 51.96% of patients had uncontrolled control blood pressure. Due to the lack of supply of drugs in health facilities and the socioeconomic profile of the users, the Popular Pharmacy Program in Brazil presents itself as an important strategy for the access of patients to their treatment. Finally, summarizing the findings, it was observed that the logistics cycle of Pharmaceutical Care in Belém - especially in the stages of planning, purchasing and dispensing drugs - does not respect the current legal framework which regulates the National Pharmaceutical Care. It was noted the lack of standardization of drugs scheduled to units located in the same region, in addition to the large difference between the conditions of purchase of medicines compared to other bids, arriving to generate price differences of up to 3000%. We conclude that the technical management of pharmaceutical care in the city of Belém is ineffective and inefficient for the care of patients with Hypertension.

(Universidade Federal do Pará, 2015-02-23) SOUSA, Kassio Cardoso; SILVA, Marcos Valério Santos da; http://lattes.cnpq.br/0379783635000306; ANDRADE, Marcieni Ataíde de; http://lattes.cnpq.br/8514584872100128
The medicine progress and improvement in general life conditions of the population led to the increase of life expectancy and contributed to population aging. There are important clinical characteristics in elderly people as the fact that those individuals show a series of alterations which interfere directly in the pharmacokinetics’ processes. The medicines constitute the most used treatments within health services, in the knowledge that, in developing countries, around 30% of the health resources are destined to those products. In that way Studies of Medicines Use are important strategic tools for the rationalization of the drugs’ use. That being so this research has as a goal to investigate the profile of prescription and use of antimicrobials for elderly persons interned in the clinics: medical clinics, clinics of infectious and parasitic diseases, the intensive treatment center and the surgical clinic of the academic Hospital João Barros Barreto (HUJBB) in the period from 2009 to 2012, aiming for observing the initiatives directed to the patient security regarding the antimicrobials use. It consists in a transversal study, observational and characteristically descriptive. The sample was composed of 299 recorded and interned patients who received the treatment with at least one antimicrobial on a regular basis. In relation to the socio-demographic profile of the elderly patients admitted in the HUJBB during the studying period, it was noticed that the most frequent gender was the feminine with 44%, and the average of the internship duration was of 18,90 days, and the most frequent age range stood between 60 and 70 years old with 46,15%, the civil status was married with 52,21%, declaring themselves ―pardos*‖ (69,90%), coming from the capital city (72,24%) and with an internship duration until 30 days utmost (82,94%). About the profile of prescription and use of antimicrobials for the elderly patients, was spotted that the cephalosporin category of third generation was the most proscribed with 29,94%, followed by the quinolones with 17,15% and Macrolides with 9,30%. Among the 23 antimicrobials found in the medicals prescriptions, the ceftriaxone was the most used with 20,13% followed by the ceftazidime with 10,50% and the clarithromycin with 9,85%. The most frequent pathologies reached the respiratory tract with: DPOC (10,16%), bronchiectasis infecting (8,07%) and pneumonia (4,30%) and the most frequent administration route used for elderly people was the intravenous with 84%. Combining the infection state of the respiratory tract (28,13%) with the most frequent use of antimicrobials of the cephalosporin category and the quinolones’ one, 47,09% were totalized. As for the clinical state outcome, 72% of the patients were discharged. The prescription profile for the rational use of antimicrobials for elderly people is provided in the advocated directives for the rational use of the medicines, as well as intended for the patient security.
