Autologous stem cell transplantation improves quality of life in economically challenged, Brazilian multiple myeloma patients

OBJECTIVES: 1) To characterize the impact of multiple myeloma on the quality of life of patients treated in two public institutions in São Paulo State, Brazil, using a generic Short Form 36 Health Survey and a questionnaire specific for oncologic patients (QLQ-C30) upon diagnosis, after the clinical treatment, and at day +100 after autologous stem cell transplantation; 2) to evaluate whether autologous stem cell transplantation can improve the quality of life of our economically challenged population aside from providing a clinical benefit and disease control. METHODS: We evaluated 49 patients with multiple myeloma (a total of 70 interviews) using the two questionnaires. The scores upon diagnosis, post-treatment/pre-autologous stem cell transplantation, and at D+100 were compared using ANOVA (a comparison of the three groups), post hoc tests (two-by-two comparisons of the three groups), and paired t-tests (the same case at two different times). RESULTS: Of the included patients, 87.8% had a family budget under US $600 (economic class C, D, or E) per month. The generic Short Form 36 Health Survey questionnaire demonstrated that physical function, role-physical, and bodily pain indices were statistically different across all three groups, favoring the D+100 autologous stem cell transplantation group (ANOVA). The questionnaire specific for oncologic patients, the QLQ-C30 questionnaire, confirmed what had been demonstrated by the Short Form 36 Health Survey with respect to physical function and bodily pain, with improvements in role functioning, fatigue, and lack of appetite and constipation, favoring the D+100 autologous stem cell transplant group (ANOVA). The post hoc tests and paired t-tests confirmed a better outcome after autologous stem cell transplantation CONCLUSION: The questionnaire specific for cancer patients seems to be more informative than the generic Short Form 36 Health Survey questionnaire and reflects the real benefit of autologous stem cell transplantation in the quality of life of multiple myeloma patients in two public Brazilian institutions that provide assistance for economically challenged patients.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Federal de São Paulo (UNIFESP)Santa Casa de Misericórdia de São Paulo Faculdade de Ciências MédicasUniversidade Federal de São Paulo (UNIFESP) Departamento de MedicinaCedars-Sinai Outpatient Cancer CenterUNIFESP, Depto. de MedicinaSciEL

Emerging applications of Sterculia striata gum in medical, pharmaceutical, and environmental fields: prospects and challenges

Trees of the genus Sterculia produce acidic polysaccharides with high viscosity and the ability to form gels in water. This work emphasized the species Sterculia striata and the uses of its plant derivatives, such as seeds, fruits, stem bark, and exudates. The species showed prospects for industrial application (seeds with high protein content, fruits with antioxidant potential, and stem bark with anti-inflammatory, antinociceptive, and gastroprotective potential). From a physicochemical and rheological point of view, the exudate has a high molar mass value; it contains uronic acid, galactose, rhamnose, and xylose. Sterculia striata gum (SSG) is highly viscous in solution and can form thermoreversible gels where gelation conditions depend on the purification method, acetyl groups, and presence of salt. Due to the presence of carboxylic acid groups, polyanionic behaving SSG allow the formation of polyelectrolyte complexes, which have been used in drug delivery systems (DDS) to encapsulate drugs such as antimalarial drugs, improve essential oil stability and obtain films for antimicrobial purposes. This review contributes to the understanding of the use of this biomaterial, providing a basis for new research on its different applications and industrial use, with a focus on the pharmaceutical, medical, food, and environmental fields.info:eu-repo/semantics/publishedVersio

Quality of life in liver transplant recipients and the influence of sociodemographic factors

Abstract OBJECTIVE To verify the influence of sociodemographic factors on the quality of life of patients after liver transplant. METHOD Cross-sectional study with 150 patients who underwent liver transplant at a referral center. A sociodemographic instrument and the Liver Disease Quality of Life questionnaire were applied. The analysis of variance (ANOVA) was performed, as well as multiple comparisons by the Tukey test and Games-Howell tests when p <0.05. RESULTS Old age had influence on domains of symptoms of liver disease (p = 0.049), sleep (p = 0.023) and sexual function (p = 0.03). Men showed better significant mean values than women for the loneliness dimension (p = 0.037). Patients with higher educational level had higher values for the domain of stigma of liver disease (p = 0.014). There was interference of income in the domains of quality of social interaction (p = 0.033) and stigma of the disease (p = 0.046). CONCLUSION In half of the quality of life domains, there was influence of some sociodemographic variable
