Clinical efficacy of stem-cell therapy on diabetes mellitus: A systematic review and meta-analysis.

OBJECTIVE: This systematic literature review aims to compare the efficacy and safety of traditional and stem cell (SC) therapies for type 1 (T1DM) and type 2 (T2DM) diabetes mellitus patients. METHODS: The PubMed, SciELO, BVS, and Medline databases were searched, and 38 original articles were selected, which included 647 control cases and 654 treatments with three-, six- and twelve-month follow-ups of T1DM and T2DM patients. The efficacy of stem cell therapy was validated by comparing laboratory parameters such as fasting blood glucose and C-peptide levels before and after treatment. The REML model was chosen for random effects, and the inverse of variance was used for fixed effects. The statistical analysis was carried out using Bioestat 5.0 and STATA 16.0 software. RESULTS: All SC treatments significantly reduced the need for insulin following six and twelve months of treatment, whereas there was no significant decrease after three months. Fasting blood glucose and glycosylated hemoglobin levels were significantly reduced in all follow-ups with SC. In addition, SC treatment caused a significant increase in C-peptide levels. Bone marrow hematopoietic stem cell therapy produced better results than the conventional drug treatment for diabetes mellitus (semagglutide). CONCLUSION: The results with SC were significantly better, regardless of the follow-up period. Studies have proven cell therapy to be beneficial, safe, and effective.

Effects of antifungal agents in sap activity of Candida albicans isolates.

Some antifungal agents have shown to exert effects on expression of virulent factors of Candida as the production of secretory aspartyl proteinase (Sap). In this study, we sought to determine and to compare the influence of fluconazole and voriconazole in proteinase activity of this microorganism. Thirty-one isolates obtained from oral mucosa of human immunodeficiency virus positive (HIV) patients were used in this study. The minimal inhibitory concentrations (MIC) of fluconazole and voriconazole were determined using the broth microdilution method with RPMI 1640 medium and with yeast carbon base-bovine serum albumin (YCB-BSA) medium. The Sap activity following by digestion of BSA as substrate was determined for four Candida albicans strains arbitrarily chosen according to susceptibility (susceptible or resistant) to fluconazole or voriconazole. Besides, the SAP1 to SAP7 genes were screened by PCR for the same isolates that were determined by the Sap activity. In vitro susceptibility testing using the two media presented similar MIC values. Increased Sap activity was observed in resistant isolates on presence of drugs, but the Sap activity by susceptible isolates to azoles showed different behavior on the presence of drug. We detected the presence of SAP1 to SAP7 genes from all susceptible or resistant C. albicans isolates. The present study provides important data about the proteinase activity and the presence of genes of SAP family in fluconazole and voriconazole susceptible or resistant C. albicans isolates.

Antifungal activities of azole agents against the Malassezia species.

In this paper, we identified 95 Malassezia isolates by morphological and biochemical criteria and assessed the in vitro activity of fluconazole, itraconazole, ketoconazole and voriconazole by broth microdilution against these species using slightly modified Leeming-Notman medium. The Malassezia isolates were identified as M. furfur (74), M. sympodialis (11), M. obtusa (8) and M. globosa (2). The modified Leeming-Notman medium used for susceptibility testing allowed good growth of Malassezia spp. Visual reading of the minimal inhibitory concentration (MIC) was readily achieved until Day 5 of incubation at 32 degrees C. Although high MIC values of 16 microg/mL for fluconazole were observed in 9.5% of Malassezia isolates, in general these microorganisms were susceptible to all drugs studied. Interestingly, one M. globosa isolate showed high MIC values for voriconazole, itraconazole and fluconazole. For the 95 strains, the MIC ranges were <0.03-4 microg/mL for ketoconazole, <0.03 to >16 microg/mL for voriconazole, <0.125 to >64 microg/mL for fluconazole and <0.03-16 microg/mL for itraconazole. In summary, the good reproducibility and visual readings obtained using modified Leeming-Notman medium suggest that this medium should be proposed for antifungal testing of drugs against Malassezia spp.

[Phenotyping of bacteria isolated in blood cultures from critical patients]. / Fenotipagem de bactérias isoladas em hemoculturas de pacientes críticos.

Bloodstream infections are a serious complication among critical patients. The detection of microbial pathogens in blood cultures is an important diagnostic tool. This study aimed to isolate and characterize bacteria from the blood of patients admitted to the clinical intensive care unit of a teaching hospital, between April 2003 and April 2004. The bacteria isolated were identified by biochemical/enzymatic tests and detection of the antimicrobial susceptibility profile using the disk diffusion method. A total of 304 blood cultures from 195 patients were evaluated. Forty-nine (16.1%) of the blood cultures presented microbe development. The predominant species was Pseudomonas stutzeri (18.2%). Gram-positive cocci and enterobacteria showed greater resistance to ampicillin; vancomycin and linezolid were the most active agents for Gram-positive cocci and carbapenems for Gram-negative rods. Because of the impact of bloodstream infection within the hospital context, additional studies are needed in order to give backing for prevention and control measures.

Asymptomatic oral carriage of Candida species in HIV-infected patients in the highly active antiretroviral therapy era.

Oropharyngeal candidiasis is the most common opportunistic fungal infection in individuals infected with human immunodeficiency virus. CD4+ lymphocytes count and the quantification of viral RNA in blood plasma have been found to be the main markers of HIV disease progression. The present study was conducted to evaluate Candida sp. diversity in the oral cavity of HIV-infected patients and to determine whether there was association of CD4+ cell count and viral load with asymptomatic oral Candida carriage. Out of 99 HIV-positive patients studied, 62 (62.6%) had positive culture for Candida (oral carriage) and 37 patients (37.4%) had Candida negative culture (no oral carriage). The etiologic agents most common were C. albicans and C. tropicalis. The range of CD4+ was 6-2305 cells/mm3 in colonized patients and 3-839 cells/mm3 for non-colonized patients, while the viral load was 60-90016 copies/mL for colonized patients and 75-110488 copies/mL for non colonized patients. The viral load was undetectable in 15 colonized patients and in 12 non colonized patients. Our results showed that there was no significant difference of the variables CD4+ cell count and viral load between oral candida carriage and no oral candida carriage patients.

Apesar da ampla disponibilidade de dispositivos para leitura de tiras reativas para análise de urina, falhas potenciais persistem na rotina baseada na interpretação humana. O objetivo deste estudo foi desenvolver e avaliar o desempenho de um dispositivo baseado em Arduino para a leitura semi-automática de parâmetros de fitas reativas. O parâmetro glicose de um modelo de tira reativa comercial foi analisado pelo sistema, que prevê a concentração do analito submetendo a cor observada na tira a um modelo de regressão, ajustado a um banco de dados de padrões de cores. O sistema foi avaliado através da leitura de 80 tiras com 16 amostras de concentrações aleatórias de glicose. O menor coeficiente de variação após cinco leituras replicadas foi de 4,5% e o mais alto foi de 16,6% (MSE = 68,7 mg / dL; r = 0,979). O dispositivo apresentou resultados satisfatórios mais baixos custos. Para torná-lo útil na rotina laboratorial, seriam necessárias novas experiências com outros parâmetros e outras classes de tiras reativas para análise de urina.

Although many devices are available to read urinalysis reactive strips, potential failure, based on human interpretation, persists in routine tasks. Current study develops and evaluates the performance of an Arduino-based device for the semi-automated reading of reactive strip parameters. The glucose parameter of a commercial reactive strip model was analyzed by the system, which predicts analyte concentration by submitting the color observed in the strip to a regression model, adjusted to a database of color patterns. The system was assessed by reading of 80 strips with 16 samples of random glucose concentrations. The lowest coefficient of variation after five replicated readings was 4.5% and the highest was 16.6% (MSE=68.7 mg/dL; r=0.979). The device featured satisfactory results plus low costs. To make it useful in the laboratory routine, further experiments with other parameters and other classes of urinalysis reactive strips would be necessary.

Doenças associadas à deficiência do sistema complemento / Diseases associated with the deficiency of the complement system

Introdução: O sistema complemento é composto por diversas proteínas plasmáticas e é um importante mecanismo de defesa da imunidade inata e adquirida, que exerce funções homeostáticas e fisiológicas, como a remoção de células apoptóticas e complexos imunes. A deficiência neste mecanismo pode ser hereditária ou adquirida, e leva ao aumento da susceptibilidade a doenças infecciosas e não infecciosas, raras e fatais. Objetivo: Descrever as principais causas e consequências da deficiência do sistema complemento e relacioná-las com múltiplas patologias. Material e Métodos: Trata-se de uma revisão bibliográfica narrativa, tendo como base de dados, artigos publicados no Scientific Electronic Library Online (SciELO), National Library of Medicine (PubMed), Medical Literature Analysis and retrieval System Online (MEDLINE), nos últimos 5 anos. Resultados: A associação do complemento e doenças foram observadas em situações de deficiência do sistema complemento, anormalidades na regulação e nas inflamações. Mutações genéticas ou aumento do consumo do complemento levam à ativação imprópria ou excessiva do complemento, podendo conduzir a consequências lesivas e ao desenvolvimento de diversas doenças, como, lúpus eritematoso sistêmico, síndrome urêmica hemolítica atípica, glomerulopatia C3, hemoglobinúria paroxística noturna, glomerulonefrite pós-infecciosas, artrite reumatoide, dentre outras. Conclusão: É evidente a participação do sistema complemento na patogênese e patogenia de diversas doenças. O investimento em pesquisas, que visem ampliar o entendimento do papel do mecanismo do sistema complemento, pode contribuir para o desenvolvimento de intervenções terapêuticas paliativas e ou de cura de diversas doenças, com a consequente melhoria da qualidade de vida dos indivíduos acometidos.

Introduction: The complement system is composed of several plasma proteins and is an important defense mechanism of innate and acquired immunity, which exerts homeostatic and physiological functions, such as the removal of apoptotic cells and immune complexes. Deficiency in this mechanism may be hereditary or acquired, and leads to increased susceptibility to infectious and non-infectious, rare and fatal diseases. Objective: To describe the main causes and consequences of the deficiency of the complement system and to relate them to multiple pathologies. Material and Methods: This is a bibliographical narrative review, based on data published in SciELO (Scientific Electronic Library Online), PubMed (National Library of Medicine), MEDLINE (Medical Literature Analysis and retrieval System Online), last five years. Results:The associations of complement and diseases were observed in situations of deficiency of the complement system, abnormalities in regulation and inflammation. Genetic mutations lead to inappropriate or excessive activation of the complement, as well as increased the consumption of the complement. This can lead to harmful consequences and the development of several diseases, such as systemic lupus erythematosus, atypical hemolytic uremic syndrome, C3 glomerulopathy, nocturnal paroxysmal hemoglobinuria, postpartum glomerulonephritis, infectious diseases, rheumatoid arthritis, among others. Conclusion: The participation of the complement system in the pathogenesis and pathogenesis of several diseases is evident. Investing in research, aimed at broadening the understanding of the role of the complement system mechanism, may contribute to the development of palliative therapeutic interventions and or cure of various diseases, with the consequent improvement in the quality of life of affected individuals.

Síndrome de Rett: uma revisão da literatura / Rett Syndrome: a review of the literature

Síndrome de Rett (SR) é uma desordem neurológica severa do desenvovimento, e a sua incidência é de 1:10.000 nascimentos do sexo feminino, uma das causas genéticas mais comuns de atraso mental severo em mulheres. O desenvolvimento é aparentemente normal nos primeiros seis a 18 meses de vida até que ocorre a regressão das habilidades cognitivas, sociais e motoras. A progressão e severidade da desordem são avaliadas de forma clássica e divididas em estágio I, de estagnação precoce, estágio II, rapidamente destrutivo, estágio III, pseudo estacionária, e estágio IV, de deterioração motora tardia. As mutações no gene ligado ao X metil-CpG de ligação a proteína 2 (MECP2) está presente na maioria das pacientes com a SR. O tratamento fisioterapêutico é bastante eficaz, visto que melhora ou mantém as capacidades funcionais, funções sensoriais e motoras na SR. Benefícios estes que causam grande impacto na qualidade de vida desses indivíduos com deficiências severas.

Rett syndrome (RS) is a severe neurological developmental disorder, and its incidence is 1: 10,000 female births, one of the most common genetic causes of severe mental retardation in females. The development is apparently normal in the first six to 18 months of life until regression occurs cognitive, social and motor skills. The progression and severity of the disorder are assessed and classically divided into stage I, early stagnation, stage II, rapidly destructive, stage III, stationary pseudo, and stage IV, the late motor deterioration. Mutations in the X-linked gene 2 protein binding of methyl-CpG (MECP2) is present in most patients with MR. The physical therapy is quite effective, as it improves or maintains the funcional, sensory and motor functions in SR. These benefits that greatly impact quality of life of individuals with severe disabilities.

Differences in exoenzyme production and adherence ability of Candida spp. isolates from catheter, blood and oral cavity.

Phospholipase and proteinase production and the ability of adhesion to buccal epithelial cells (BEC) of 112 Candida isolates originated from oral cavity of HIV infected patients and from blood and catheter of intensive care unit patients were investigated. The proteinase production was detected by inoculation into bovine serum albumin (BSA) agar and the phospholipase activity was performed using egg yolk emulsion. A yeast suspension of each test strain was incubated with buccal epithelial cells and the number of adherence yeast to epithelial cells was counted. A percentage of 88.1% and 55.9% of Candida albicans and 69.8% and 37.7% of non-albicans Candida isolates produced proteinase and phospholipase, respectively. Non-albicans Candida isolated from catheter were more proteolytic than C. albicans isolates. Blood isolates were more proteolytic than catheter and oral cavity isolates while oral cavity isolates produced more phospholipase than those from blood and catheter. C. albicans isolates from oral cavity and from catheter were more adherent to BEC than non-albicans Candida isolates, but the adhesion was not different among the three sources analyzed. The results indicated differences in the production of phospholipase and proteinase and in the ability of adhesion to BEC among Candida spp. isolates from different sources.

Introdução: O câncer de mama é a segunda neoplasia mais frequente no mundo e a primeira mais comum no sexo feminino. Dados epidemiológicos apontam o efeito de agentes carcinogênicos e fatores ambientais para maior susceptibilidade em desenvolver o câncer de mama. No contexto das avaliações moleculares, o polimorfismo nulo do gene GSTM1 é comumente estudado na tentativa de associá-lo ao desenvolvimento desta neoplasia. Objetivo: Avaliar se os indivíduos que apresentam o polimorfismo nulo para o gene GSTM1 possuem susceptibilidade ao câncer de mama. Métodos: Realizou-se meta-análise com 10 estudos do tipo caso-controle, que apresentavam pacientes com confirmação histológica de câncer de mama e que faziam uso da PCR e/ou sequenciamento de DNA para determinar o polimorfismo nulo do gene GSTM1. A análise foi realizada após a coleta dos dados necessários (autor, ano de publicação, país e resultados). Os cálculos estatísticos e a representação dos dados foram obtidos com o auxílio do software BioEstat® 5.0. Resultados: O total de indivíduos, após o agrupamento dos dados dos estudos, foi de 7.607 (3.759 casos e 3.848 controles). As frequências para o polimorfismo nulo do gene GSTM1 em pacientes com câncer de mama foram, respectivamente, 51,0% no grupo casos e 50,3% no grupo controle. A análise dos dados obtidos revelou OR: 0,967 e IC95% 0,883?1,060. Conclusão: Conforme os dados obtidos na meta-análise, não foi encontrada associação significativa entre o polimorfismo nulo do gene GSTM1 e o desenvolvimento do câncer de mama. Assim, os resultados do presente estudo mostram que o polimorfismo em questão não alterou suscetibilidade ao câncer de mama, portanto, devem-se levar em consideração outros fatores com maior significância, como: tabagismo, outros marcadores genéticos, tais como BRCA1 e BRCA2, paridade, entre outros.

Introduction: Breast cancer is the second most common cancer worldwide and the first more common in females. Epidemiological data show the effect of carcinogens and environmental factors in the increased susceptibility of developing breast cancer. In the context of molecular assessments, the null polymorphism of GSTM1 gene is commonly studied in an attempt to associate with the development of this neoplasm. Objective: To evaluate whether individuals with the GSTM1-null polymorphism possess susceptibility to breast cancer. Methods: It was conducted a meta-analysis of 10 case-control studies, which had patients with histological confirmed breast cancer and used PCR and/or DNA sequencing to determine the null polymorphism of GSTM1 gene. The analysis was performed after gathering the necessary data (author, publication year, country and results). Statistical calculations and the representation of the data were obtained with the help of BioEstat® 5.0 software. Results: The total number of individuals, after grouping the data was 7,607 (3,759 cases and 3,848 controls). The frequencies for the null polymorphism of GSTM1 gene were, respectively, 51.0% in the case group and 50.3% in the control group. The analysis of the obtained data revealed OR: 0.967 and 95%CI 0.883?1.060. Conclusion: According to the data obtained by meta-analysis it was not found significant association between GSTM1-null polymorphism and the development of breast cancer. Thus, the results of this study revealed that the polymorphism in question did not change the susceptibility to breast cancer, so it should be considered other factors with greater significance, such as smoking, other genetic markers like BRCA1 and BRCA2, parity, among others.

RESULTS: The characteristics identified as important for training teachers were dedication and commitment to teaching, continued professional enhancement allied to teaching and research, organization and discipline, enjoying teaching, ethics, good relationship with students, linking theoretical to practical learning, scientific accuracy and an interdisciplinary approach when teaching. CONCLUSION: The study found that learning with the old mentors was important, without dispensing of the need for specific teacher training.

Comparison of in vitro activity of five antifungal agents against dermatophytes, using the agar dilution and broth microdilution methods.

The purpose of this study was to compare the agar dilution and broth microdilution methods for determining the minimum inhibitory concentration (MIC) of fluconazole, itraconazole, ketoconazole, griseofulvin and terbinafine for 60 dermatophyte samples belonging to the species Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis. The percentage agreement between the two methods, for all the isolates with < 2 dilutions that were tested was 91.6% for ketoconazole and griseofulvin, 88.3% for itraconazole, 81.6% for terbinafine and 73.3% for fluconazole. One hundred percent agreement was obtained for Trichophyton mentagrophytes isolates evaluated with ketoconazole and griseofulvin. Thus, until a reference method for testing the in vitro susceptibility of dermatophytes is standardized, the similarity of the results between the two methods means that the agar dilution method may be useful for susceptibility testing on these filamentous fungi.
