Educação em saúde em hanseníase: estratégia na educação básica, Parnamirim/RN

Leprosy is an ancient disease that still stands as a public health problem worldwide, especially in the considered developing countries. Of these, Brazil still has large areas of endemicity. The disease remains high among those younger than 15 years old. In this group, the national index achieves 0.6 every 10 000 inhabitants and reaches 2 in the North and Midwest of Brazil. Therefore, the plan of the Ministry of Health is to prioritize the fight against disease in critical areas, providing early diagnosis and timely treatment, especially for patients under 15 years old. This research aimed to: identify the knowledge of students from three schools of basic education in Parnamirim/RN about the risk of getting ill in leprosy; conduct them health education on this topic. An exploratory-descriptive study with quantitative and qualitative nature. Data collection consists of two steps: questionnaire and health education on leprosy. The study was approved by the Research Ethics Committee (REC) of UFRN through the opinion nº 204/2009. Quantitative data obtained were organized, categorized, typed and submitted to the Microsoft Office - Excel for quantitative analysis with simple percentage. Qualitative data were subjected to a content analysis according to Bardin. The sample consisted of 164 students of basic education, most of which is: 1st year of high school, from 11 to 15 years, in the afternoon shift, female gender, skin color white and residents in the municipality of Parnamirim/RN. Still, each student living with four people curiously did not respond in relation to occupation of the father. But the same answered their mother as a housewife and a family income of one to less than four minimum wages. There have been significant results compared the performance of health education in leprosy. Initially, students possessed little knowledge about leprosy. Subsequent to health education, most knew the answer about the disease, transmission, cause, where to get help in case of suspicion of leprosy and the need for the people who lives with leprosy patients to also seek for help, the understanding about if it is treatable or not. Content analysis has established the following themes: axis I, what I do not know about leprosy: cure, fear and prejudice. Axis II, what I know about leprosy, we identified: cure, effectiveness of health education and social exclusion in the past. It is considered the scope of the proposed objectives by matching the effectiveness of health education on leprosy in basic education in Parnamirim/RN; emphasizes, therefore, the importance of understanding the knowledge of public school students. It is expected of them to detect early cases of leprosy in their communities; encourage adherence to treatment as quickly as possible; prevent disability; reduce the stigma surrounding the disease.

Antiviral effect of Guazuma ulmifolia and Stryphnodendron adstringens on poliovirus and bovine herpesvirus

Crude extract (CE) and aqueous (AqF) and ethyl acetate (EtOAcF) fractions of Guazuma ulmifolia LAM., Sterculiaceae and the corresponding AqF, EtOAcF of Stryphnodendron adstringens (MART.) COVILLE, Leguminosae were tested for their antiviral activity against poliovirus 1 (P-1) and bovine herpesvirus 1 (BHV-1) in HEp2 cultured cells. The antiviral activity was monitored by plaque assay and immunolluorescence assay (IFA) under virucidal and therapeutic protocols. The therapeutic protocol demonstrated statistically significant positive results with both plants and for both virus strains. The highest percentages of viral inhibition were found for G. ulmifolia EtOAcF which inhibited BHV-1 and P-1 replication by 100% and 99%, respectively (p < 0.05, Student's t-test). For S. adstringens, AqF was the most efficient, inhibiting BHV-1 and P-1 by 97% and 93%, respectively (p < 0.05). In the virucidal protocol, G. ulmifolia CE inhibited the replication of BHV-1 and P-1 by 60% and 26%, respectively (p < 0.05), while, for S. adstringens, inhibition of 62% (p < 0.05) was demonstrated only with EtOAcF for P-1. IFA demonstrated that the greatest reduction in fluorescent cell number occurred with G. ulmifolia, under the therapeutic protocol for both virus strains. However, AqF and EtOAcF of S. adstringens were most efficient with the virucidal protocol for P-1 In conclusion, we demonstrated that G. ulmifolia and S. adstringens inhibited BHV-1 and P-1 replication, as well as, blocked the synthesis of viral antigens in infected cell cultures.

Portable MP3 player as low-cost data logger

Non-audio signals have been recorded in the flash ROM memory of a portable MP3 player, in WAV format file, to examine the possibility of using these cheap and small instruments as general-purpose portable data loggers. A 1200-Hz FM carrier modulated by the non-audio signal has replaced the microphone signal, while using the REC operating mode of the MP3 player, which triggers the voice recording function. The signal recovery was carried out by a PLL-based FM demodulator whose input is the FM signal captured in the coil leads of the MP3 player's earphone. Sinusoidal and electrocardiogram signals have been used in the system evaluation. Although the quality of low frequency signals needs improvement, overall the results indicate the viability of the proposal. Suggestions are made for improvements and extensions of the work.

Prospective Evaluation of Dietary Treatment in Childhood Constipation: High Dietary Fiber and Wheat Bran Intake Are Associated With Constipation Amelioration

Objectives: The aim of the study was to evaluate, over 24 months, the intake of dietary fiber (DF) and the bowel habit (BH) of constipated children advised a DF-rich diet containing wheat bran.Patients and Methods: BH and dietary data of 28 children with functional constipation defined by the Boston criteria were obtained at visit 1 (V1, n = 28) and at 4 follow-up visits (V2-V5, n = 80). At each visit the BH was rated BAD (worse/unaltered; improved but still complications) or RECOVERY (REC) (improved, no complications; asymptomatic), and a food intake questionnaire was applied. DF intake was calculated according to age (year)+5 to 10 g/day and bran intake according to international tables. Nonparametric statistics were used.Results: Median age (range) was 7.25 years (0.25-15.6 years); 21 children underwent bowel washout (most before V1/V2), and 14 had the last visit at V3/V4. DF intake, bran intake, and the BH rate significantly increased at V2 and remained higher than at V1 through V2 to V5. At V1, median DF intake was 29.9% below the minimum recommended and at the last visit 49.9% above it. Twenty-four children accepted bran at 60 visits, at which median bran intake was 20 g/day and median proportion of DF due to bran 26.9%. Children had significantly higher DF and higher bran intake at V2 to V5 at which they had REC than at those at which they presented BAD BH. DF intake > age+10 g/day was associated with bran acceptance and REC. At the last visit 21 children presented REC (75%); 20 of them were asymptomatic and 18 were off washout/laxatives.Conclusions: High DF and bran intake are feasible in constipated children and contribute to amelioration of constipation.

Differential MMP-2 and MMP-9 Activity and Collagen Distribution in Skeletal Muscle from pacu (Piaractus mesopotamicus) During Juvenile and Adult Growth Phases

Here, we evaluated collagen distribution and matrix metalloproteinases (MMPs) MMP-2 and MMP-9 activities in skeletal muscle of pacu (Piaractus mesopotamicus) during juvenile and adult growth phases. Muscle samples from juvenile and adult fishes were processed by histochemistry for collagen system fibers and for gelatin-zymography for MMP-2 and MMP-9 activities analysis. Picrosirius staining revealed a myosept, endomysium, and perimysium-like structures in both growth phases and muscle types, with increased areas of collagen fibers in adults, mainly in red muscle. Reticulin staining showed that reticular fibers in the endomysium-like structure were thinner and discontinuous in the red muscle fibers. The zymography revealed clear bands of the pro-MMP-9, active-MMP-9, intermediate-MMP-2, and active-MMP-2 forms in red and white muscle in both growth phases. MMP-2 activity was more intense in juvenile than adult muscle fibers. Comparing the red and white muscle types, MMP-2 activity was significantly higher in red muscle in adult phase only. The activity of MMP-9 forms was similar in juvenile red and white muscles and in the adult red muscle, without any activity in adult white muscle. In conclusion, our results show that, in pacu, the higher activities of MMP-2 and -9 are associated with the rapid muscle growth in juvenile age and in adult fish, these activities are related with a different red and white muscle physiology. This study may contribute to the understanding muscle growth mechanisms and may also contribute to analyse red and the white muscle parameters of firmness and softness, respectively, of the commercial product.
