The Curaua. （Ananaserectifolius LB Smith） is a species belonging to the family Bromeliaceae. Occurs in the states of Para, Amazonas, Amapa, Acre, Mato Grosso and Goia s, has two varieties, purple and white, and its fibers are used in automotive and textile industries due to its strength, softness and lightweight. Currently, only the fiber is used in industry, the rest is considered waste However, this residue contains compounds with important properties to be discovered and studied. An enzyme complex found in this residue is bromelain, a group of proteolysis＇ enzymes with application in several areas such as in the food, pharmaceutical and cosmetics industries. Today, its use is aiming the pharmaceutical industry, the production of ointments, gels, creams and lotions because they offer a wide range of therapeutic efficacies： antiedemas, anti-inflammatory, antithrombotic and fibrinolytic activities. This work studied the enzyme purification and recovery presented in the leaves of Curaua by means of an ATPS （aqueous two-phase system） PEG 4000/potassium phosphate. The protein content was measured by Bradford reagent and the enzymatic activity was measured by the Biuret reagent. Batch assays were performed aiming the enzyme extraction and recuperation, using the partition coefficient as indicator. It was used pH 7.0, 8.0 and 9.0, varying the proportional composition between the polymeric and the saline phases （tie-lines）. The white variety of Curaua. was used. The best purification factor was 4.53 and about 113.04 μg/mL of total protein measured by Bradford.

Tuberculosis is one of the 10 leading causes of death in the world. Its symptoms include fever, malaise, weakness, weight loss, chest pain, cough, expectoration, shortness of breath and sepsis, which is its most frequent complication. Due to these symptoms, many patients with tuberculosis require admission to the Intensive Care Unit, where they usually are placed on mechanical ventilation. Tuberculosis is more prevalent in the population in situations of social and economic vulnerability. The main factors that interfere with adherence to treatment and the prognosis of these patients are the patient’s support network and their socioeconomic status. We present the following report of a long-time smoker patient, with chronic kidney disease and previous treatment for tuberculosis, who was brought to the emergency room due to lowering of the sensorium, and was immediately placed on mechanical ventilation. The tests suggested sepsis with a respiratory focus, so a search for Alcohol-Acid-Resistant Bacillus was carried out, with a positive result. The patient was transferred to the Intensive Care Unit due to tachycardia and acute respiratory failure. The patient was a smoker with a high tobacco load, chronic kidney disease, in addition to precarious economic, educational and self-care conditions. This report shows that patients with tuberculosis and its complications can be stabilized through known pharmacological treatment. However, the most effective measure to interrupt the transmission of the disease remains the early diagnosis and the provision of adequate treatment, with guidelines aimed at the cessation of harmful habits, such as smoking.

Health 2015年第4期7卷 423-429页

作者： Natasha Marques Frota Lívia Moreira barros Francisco Gilberto Fernandes Pereira Máguida gomes da Silva Jennara Candido do Nascimento Monaliza Ribeiro Mariano Joselany áfio Caetano department of Nursing Federal University of Ceará Fortaleza Brazil

This is a qualitative study that aims to describe the opinion of nursing students on the use of an educational hypermedia on Peripheral Venipuncture. We interviewed 16 nursing students of a private university on second semester of 2014. The interviews allowed the identification of units of meaning and categorization by content analysis and led to four categories: influence of hypermedia on learning, educational technology as support to teaching classroom, contribution of hypermedia for professional practice and access difficulties. Hypermedia showed positive results as most scholars reported that the material helped in learning and generated autonomy and interactivity in the moment of studying. However some reported difficulties in access hypermedia related mainly to the server used. So hypermedia proved to be a valuable tool to use, since it favored the learning and aroused the interest and curiosity of students.

Correlation between the Six-Minute Walk Test and Subjective Functional Class in Patients with Heart Failure

引用

World Journal of Cardiovascular Diseases 2023年第4期13卷 205-213页

作者： Davi Muzi Rios Gabriela Lira devens Leticia Admiral Louzada Priscila Cabral gomes Coelho Lima Rodolfo Costa Sylvestre Vinicius Angelo Astolpho Lucas Crespo de barros Larissa Novaes Paganini Lucas Martins Frizzera Borges Renato Giestas Serpa Osmar Araujo Calil Luiz Fernando Machado Barbosa Roberto Ramos Barbosa department of Cardiology Santa Casa de Misericórdia de Vitória Hospital Vitória Brazil School of Medicine Santa Casa de Misericórdia Vitória Brazil

Introduction: The Six-Minute Walk Test (6MWT) is an inexpensive method to objectively evaluate physical capacity or limitation and stratify prognosis in patients with Heart Failure (HF). Since the clinical perception of symptoms may be adapted or compromised, regular evaluation from medical interviews often fails to determine functional classification. This study aimed to assess the correlation between New York Heart Association Functional Class (NYHA-FC) and the distance walked in the 6MWT. Methods: We conducted a cross-sectional observational study that included patients with HF with reduced ejection fraction followed up at an outpatient service of a teaching hospital, from August 2018 to April 2019. Patients in NYHA-FC I, II, or III were included. We compared NYHA-FC subjectively obtained during the consultation with the 6MWT performed after medical consultation, and the correlation between these two parameters was assessed. Results: The study included 70 patients with HF, 41 (58.6%) of whom were female. The mean age was 61.2 ± 12.7 years. The most prevalent etiologies were dilated idiopathic cardiomyopathy (35.7%) followed by ischemic cardiomyopathy (25.7%). The mean ejection fraction was 34.1% ± 9.8%. The average distance walked in the 6MWT by NYHA-FC I patients was 437.8 ± 95.8 meters, NYHA-FC II 360.1 ± 96.4, and NYHA-FC III 248.4 ± 98.3. Functional class measured by the 6MWT was different than that estimated by NYHA-FC in 34 patients (48.6%), 23 (32.9%) for a higher functional class and 11 (15.7%) for a lower one (p = 0.07). Pearson’s correlation coefficient between NYHA-FC and the 6MWT was -0.55. Conclusion: There was a moderate correlation between the subjective NYHA-FC and the 6MWT. The 6MWT revealed a different classification from NYHA-FC in almost half of the patients. Among those who presented discrepancies between methods, 6MWT reclassification towards a higher functional class was more common.
