Comparison between the isokinetics parameters of shoulder joint and independence functional level in manual wheelchair users / Comparação entre parâmetros isocinéticos da articulação do ombro com nível de independência funcional em usuários de cadeira de rodas manual

Shoulder pain is a common complaint in the wheelchair user's population. This condition brings loss of independence and quality of life. Objective: The aim of this paper is to correlate shoulder joint isokinetic parameters and independence level of manual wheelchair users with or without pain. We hypothesize that users more independent are exposed to overuse injury of shoulder joints. Method: This is an explorative cross-sectional study with a quantitative approach. Community patients attended at a Rehabilitation Center. Manual wheelchair users. Twenty-four patients participated, we used the Functional Independence Measurement (FIM) to investigate the independent level of wheeled patients and isokinetic parameters of internal/external rotators and flexion/extension muscles of shoulder joint was collected using Biodex System 4 Pro. Statistical analyses were made by Fisher Test, Spiro-Wilk Test, Pearson Correlation test, Spearman test and the Coefficient of correlation's value was squared to estimate the percentage of variation in dependent variable, explained by independent variable. Results: Total FIM variation was between 79 and 117 and median ipsilateral strength ratio of rotator muscles were 0.94 on 75°/s and 0.95 on 150°/s for the right limb and respectively 0.96 and 0.93 for the left limb. Conclusion: Wheelchair users present internal/external rotators shoulder muscles imbalance and the covariations samples of time of injury and peak torque ratio external/internal shoulder rotators have a significant predictive value on total MIF. These results suggest that there is correlation between the studied patients and shoulder impairment.

Conclusão: Estes resultados sugerem uma correlação entre os pacientes estudados e comprometimento da articulação do ombro.

Epidemiological and cytogenetic profiles of patients with hematological malignancies and their relationship with aging

ABSTRACT Background: Hematologic neoplasms are associated with mutations in hematopoietic cells and chromosomal abnormalities. During aging, about 2-3% of the elderly have chromosomal abnormalities arising from clonal mosaicism, the immune system is impaired and the bone marrow loses its ability to replace blood cells. Objective: To describe the epidemiological and cytogenetic profile of hematological malignancies, highlighting the frequency of chromosomal alterations in these neoplasms associated with aging. Method: A retrospective cross-sectional study with analysis of karyotype exams results was performed in the Cytogenetic Laboratory of thee Blood Center of the Faculdade de Medicina de Marilia (FAMEMA) between 1998 and 2016. Blood samples from child and adult patients with different hematological malignancies treated in the Onco-hematology Outpatient Clinics of the local blood center and hospitals, and external clinics were tested. Results: Karyotype exam results of 746 patients with a mean age of 54.7 years (±23.1) were analyzed. The elderly had the highest frequency of hematological malignancies (50.9%), followed by adults (38.3%) and young people (10.7%); elderly women had the highest percentage (55.0%). Normal karyotypes (46,XX/46,XY) were more common (61.8%) compared to abnormal karyotypes, especially among the elderly (56.4%). Myeloproliferative neoplasms were an exception with 67.4% of abnormal karyotypes. Conclusion: There is a higher frequency of hematological malignancies among the elderly. It is possible to conclude that failures in genomic mechanisms and hematopoiesis with aging lead to the formation of cells with the chromosomal alterations found in hematological malignancies.

Interleukin 8 (-251 T>A) polymorphism in children and teenagers infected with Helicobacter pylori

Background Helicobacter pylori (H. pylori) is a gram-negative bacterium that colonizes the human stomach and causes a variety of gastric diseases. This study evaluated the correlations between the -251 (T>A) (rs4073) polymorphism of interleukin-8 (IL-8), the etiology of gastric disease, and H. pylori infection in pediatric and adolescent patients. Methods DNA samples were obtained from 285 gastric biopsies from pediatric patients. H. pylori was detected by PCR, whereas PCR-RFLP was used to characterize the -251 (T>A) polymorphism of IL-8. Results The histological analysis revealed the presence of gastritis in 158 patients (55.44%). H. pylori was found in 71 samples (24.9%). The -251 (T>A) polymorphism revealed that 58 (29.47%) samples were TT, 143 (50.18%) samples were TA, and 84 (20.35%) samples were AA. Conclusions Our findings suggest that IL8-251 A allele may be an important risk factor for the development of gastric disease when associated with H. pylori infection.(AU)

Lack of association among TNF-α gene expression, -308 polymorphism (G > A) and virulence markers of Helicobacter pylori

Background Tumor necrosis factor plays a critical role in the pathogenesis of gastric diseases such as gastric cancer, and an abnormal inflammatory response has frequently been observed in dyspeptic patients. Helicobacter pylori infection can induce a gastric mucosal inflammatory response that may be influenced by -308 (G > A) polymorphisms and gene expression of theTNF-α gene. Methods One hundred and thirty-four gastric biopsy samples were collected from patients of both genders (61♂ and 73♀, mean age 40.3 ± 24.2 years) with gastric symptoms. The -308 (G > A) polymorphism of TNF-α; was characterized using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The expression level was measured using real-time PCR, and relative quantification (RQ) was calculated using the comparative CT method (2-ΔΔCT). Results The analysis revealed an increase in TNF-α gene expression in patients with gastritis; on the other hand, no statistical differences were observed in patients with gastric cancer. In addition, no association was found among -308 polymorphism genotypes, virulence markers, or TNF-α gene expression. Conclusions Helicobacter pylori induces a large increase in TNF-α expression in patients with gastritis, regardless of tissue inflammation, but after the tissue becomes neoplastic, the presence of bacteria did not influence expression. These results suggest that the TNF-α; pathway may play an important role in the progression from gastritis to gastric cancer(AU)

Association among H. pylori virulence markers dupA, cagA and vacA in Brazilian patients

Only a few Helicobacter pylori-infected individuals develop severe gastric diseases and virulence factors of H. pylori appear to be involved in such clinical outcomes. Duodenal ulcer promoting gene A (dupA) is a novel virulence factor of Helicobacter pylori that is associated with duodenal ulcer development and reduced risk for gastric carcinoma in some populations. The aims of the present study were to determine the presence of dupA gene and evaluate the association among dupA and other virulence factors including cagA and vacA in Brazilian patients. Gastric biopsies were obtained from 205 dyspeptic patients (100 children and 105 adults). DNA was extracted and analyzed for the presence of H. pylori and its virulence factors using the polymerase chain reaction method.

Cytogenetic effect of 5-azacytidine in patients with hematological malignancies

BACKGROUND: Recently, the importance of cytogenetics has grown in the diagnosis, prognosis and treatment of leukemias and myelodysplastic syndromes. 5-azacytidine is a drug that has well-known cytogenetical effects and is approved in the treatment of myelodysplastic syndromes. To date, no studies have been performed to evaluate the impact of 5-azacytidine on the chromosomes of patients with hematological neoplasias. This study aimed to investigate the effects of 5-azacytidine on chromosomes of patients with different hematological malignancies using G-band analyses to identify possible cytogenetical alterations. METHODS: The peripheral blood of 18 patients with hematological malignancies and 18 controls was collected in heparinized tubes. 5-azacytidine was added, at a final concentration of 10-5M, to cultures 7 hours prior to harvest. RESULTS: Uncoiled centromeric/pericentromeric heterochromatin of chromosomes-1, 9 and 16 occurred more frequently in the patients than in controls. This higher frequency of uncoiled heterochromatin was statistically significant (p-value = 0.004) for chromosome-9. Conversely, we observed that the fragile site at 19q13 was more frequent in controls (p-value = 0.0468). CONCLUSIONS: The results of this study suggest that satellite sequences, located in the heterochromatin of chromosome-9, are hypomethylated in hematological malignancies. This hypomethylation may contribute to the disease, activating transposable elements and/or promoting genomic instability, enabling the loss of heterozygosity of important tumor suppressor genes. An investigation of the 19q13 region may help to understand whether or not the predominant occurrence of the fragile site at 19q13 in controls is due to hypermethylation of this region.

Polimorfismo da Interleucina-8 -251T>A e Helicobacter pylori / Interleukin-8 -251T>A polymorphism and Helicobacter pylori

Introdução: o Helicobacter pylori é um importante patógeno associado ao desenvolvimento de gastrite crônica, úlcera péptica e doenças gástricas. Vários autores relataram que a infiltração de células inflamatórias, incluindo neutrófilos, é um traço da patologia da mucosa gástrica associada com a infecção. Há evidências de que a inflamação está associada à gravidade das lesões gástricas. A interleucina 8 (IL-8), um membro da família das citocinas, é um ativador quimiotático de neutrófilos e linfócitos e tem sido descrito que o aumento dos níveis de IL-8 na mucosa gástrica pode estar associado com a infecção por H.pylori. Objetivos: os objetivos deste trabalho foram (i) caracterizar o polimorfismo da Interleucina-8 -251T>A (ii) e verificar a possível relação entre este polimorfismo e infecção por H.pylori. Métodos: cento e sessenta pacientes sintomáticos (com idade média de 48,7 anos) participaram do estudo: 107 pacientes positivos para H.pylori e 53 negativos, previamente diagnosticados por PCR. Os genótipos da IL-8 -251 T>A foram determinados através da reação em cadeia da polimerase (PCR) e utilização de enzimas de restrição (RFLP). Resultados e Conclusões: nossos resultados indicam que não há associação entre o polimorfismo da IL-8 -251 T>A e a infecção por H.pylori ou pelo gênero dos pacientes.

Background: Helicobacter pylori is an important pathogen associated with the development of chronic gastritis, peptic ulcer disease and gastric disease. Several authors reported that the infiltration of inflammatory cells, including neutrophils is the trace of the pathology of gastric mucosa, associated with the infection. There is high evidence that inflammation is associated with severity of gastric lesions. Interleukin-8 (IL-8), a member of cytokines family, is an activator and chemoattractant of neutrophils and lymphocytes. It has been reported that increased gastric mucosal levels of IL-8 is associated with H. pylori infection. Objective: the objectives of this paper were (i) characterize Interleukin-8 -251T>A polymorphism and (ii) to examine the possible relationship between this polymorphism and the H. pylori infection. Methods: one hundred and sixty patients, (with a mean age 48.7 years) presenting recurrent abdominal pain participated in the study: 107 H. pylori positives and 53 H. pylori negatives previously diagnosed by PCR. IL8 -251T>A genotypes were determined using a polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Results and Conclusions: our findings indicate that there is no association of IL-8 -251T>A with H. pylori-infected patients or gender of these patients and these conclusions were consistent with other reports from different population samples.

Interleukin- 8- 251T > a, interleukin -1α -889C > t and apolipoprotein e polymorphisms in Alzheimer's disease

An inflammatory process has been involved in numerous neurodegenerative disorders such as Parkinson's disease, stroke and Alzheimer's disease (AD). In AD, the inflammatory response is mainly located in the vicinity of amyloid plaques. Cytokines, such as interleukin-8 (IL-8) and interleukin-1α (IL-1α), have been clearly involved in this inflammatory process. Polymorphisms of several interleukin genes have been correlated to the risk of developing AD. The present study investigated the association of AD with polymorphisms IL-8 -251T > A (rs4073) and IL-1α-889C > T (rs1800587) and the interactive effect of both, adjusted by the Apolipoprotein E genotype. 199 blood samples from patients with AD, 146 healthy elderly controls and 95 healthy young controls were obtained. DNA samples were isolated from blood cells, and the PCR-RFLP method was used for genotyping. The genotype distributions of polymorphisms IL-8, IL-1α and APOE were as expected under Hardy-Weinberg equilibrium. The allele frequencies did not differ significantly among the three groups tested. As expected, the APOE4 allele was strongly associated with AD (p < 0.001). No association of AD with either the IL-1α or the IL-8 polymorphism was observed, nor was any interactive effect between both polymorphisms. These results confirm previous studies in other populations, in which polymorphisms IL-8 -251T > A and IL-1α-889C > T were not found to be risk factors for AD.

Helicobacter pylori detection in gastric biopsies, saliva and dental plaque of Brazilian dyspeptic patients

Helicobacter pylori is an important human pathogen that causes chronic gastritis and is associated with the development of peptic ulcer disease and gastric malignancies. The oral cavity has been implicated as a potential H. pylori reservoir and may therefore be involved in the reinfection of the stomach, which can sometimes occur following treatment of an H. pylori infection. The objectives of this paper were (i) to determine the presence of H. pylori in the oral cavity and (ii) to examine the relationship between oral H. pylori and subsequent gastritis. Gastric biopsies, saliva samples and dental plaques were obtained from 78 dyspeptic adults. DNA was extracted and evaluated for the presence of H. pylori using polymerase chain reaction and Southern blotting methods. Persons with gastritis were frequently positive for H. pylori in their stomachs (p < 0.0001) and there was a statistically significant correlation between the presence of H. pylori in gastric biopsies and the oral cavity (p < 0.0001). Our results suggest a relationship between gastric infection and the presence of this bacterium in the oral cavity. Despite this, H. pylori were present in the oral cavity with variable distribution between saliva and dental plaques, suggesting the existence of a reservoir for the species and a potential association with gastric reinfection.

cagA positive Helicobacter pylori in Brazilian children related to chronic gastritis

Helicobacter pylori is a spiral-shaped Gram-negative bacterium. It colonizes the gastric mucosa of humans and persists for decades if not treated. Helicobacter pylori infection affects more than half of the world's population and invariably results in chronic gastritis. The cagA gene is present in about 60 to 70 percent of H. pylori strains; it encodes a high-molecular-weight protein (120 to 140 kDa) and several investigators have noted a correlation between strains that possess cagA and the severity of gastric mucosal inflammation. We examined the relation between cagA status in H. pylori strains and chronic gastritis with inflammatory processes in children from Marília, São Paulo, Brazil. One-hundred-twenty-one children were analyzed histopathologically and by polymerase chain reaction (PCR) to detect H. pylori and cagA. We then looked for an association between cagA presence and inflammatory infiltration. Using histology and PCR, we found 47 percent H. pylori positive infection; 29 children were diagnosed with chronic gastritis, while 28 showed normal mucosa by histopathological analysis. CagA presence was genotyped in both groups, and an inflammatory infiltrate was studied in all infected children with chronic gastritis. We found cagA strains in 20 of 29 (69 percent) children with chronic gastritis and 18 of 28 (64 percent) with normal mucosa, demonstrating a strong relationship between the strains and the inflammatory process. We found a positive association between an inflammatory process associated with H. pylori of cagA+ strains and chronic gastritis development.

Comparison of histological and molecular diagnosis of Helicobacter pylori in benign lesions and gastric adenocarcinoma

A colonização do Helicobacter pylori está associada com gastrite crônica, úlcera péptica, metaplasia intestinal, adenocarcinoma e linfoma gástrico. O objetivo desse estudo foi comparar os resultados do diagnóstico histológico usado de rotina na detecção do H. pylori com o diagnóstico molecular. Foram utilizadas amostras de 80 lesões gástricas (gastrite crônica, gastrite atrófica, úlcera gástrica e metaplasia intestinal), 18 amostras de adenocarcinoma gástrico e 10 amostras de mucosa gástrica normal H. pylori negativas (controle). Todas as amostras foram avaliadas histologicamente (coloração com hematoxilina-eosina e Giemsa) e pela PCR com a amplificação dos genes antígeno espécie-específico (H3H4) e urease A (H5H6) do H. pylori e pelo gene humano CYP1A1, como controle da qualidade do DNA. Nas amostras de lesão benigna e adenocarcinoma gástrico, a infecção foi detectada em 43 per center (42/98) e 71 pe center (70/98), respectivamente, para os diagnósticos histológico e molecular (p = 0,0001). O teste de PCR detectou o H. pylori em 27,5 per center (22/80) das lesões gástricas benignas e em 50 per center (9/18) dos adenocarcinomas gástricos, com diagnóstico histológico negativo para essa bactéria. Cerca de 2,5 per center das amostras, exclusivamente de lesões benignas, com diagnóstico histológico positivo apresentaram resultado molecular negativo, para ambos os primers. Diferenças estatisticamente significantes foram encontradas entre os métodos histológico e molecular, em metaplasia intestinal (p = 0,0461) e adenocarcinoma gástrico (p = 0,0011), devido à subdetecção do H. pylori pelo método histológico, e provavelmente pela baixa densidade da bactéria conseqüente à atrofia severa da mucosa gástrica, nesses dois tipos de lesões. Nossos achados demonstram que o método de PCR é mais eficaz para diagnosticar a infecção por H. pylori, principalmente, em metaplasia intestinal e adenocarcinoma gástrico.

Interleucina 1Beta (IL-1Beta) na gênese do câncer gástrico / Iinterleukin 1Beta (IL-1Beta) in the development for gastric cancer

Introdução:Dentre os tumores diagnosticados em todo o mundo, o adenocarcinoma gástrico é o segundo tipo de câncer mais freqüente e representa uma das principais causas de mortalidade por câncer. O Estado do Pará apresenta elevada prevalência desta neoplasia assumindo características de saúde pública. A interleucina 1 beta (IL-1beta) modula várias funções das células gástricas parientais e desta forma, alguns estudos demonstraram que a IL-1beta age como um poderoso inibidor da secreção gástrica, com um efeito anti-secretório secundário à infecção pelo Helicobacter pylori contribuindo para hipoacidez do estômago. A ocorrência de diferentes polimorfismos no conjunto de genes da IL-1beta, estão sendo associados com o aumento da produção da mesma e elevado risco para o desenvolvimento de hipocloridria e câncer gástrico. Os diferentes alelos da IL-1beta descritos diferenciam-se por transição da base citocina para timina nas posições -511, -31 e +3954 pares de bases do sítio de início transcricional, enquanto que os diferentes alelos do receptor antagonista da L1beta(IL-NR) possuem números variáveis de uma seqüência de 87 bases localizadas no segundo intron desse gene os quais onduzem a um aumento da produção da interleucina tais como seus precursores.Objetivo:Discutir a correlação do envolvimento dos diferentes polimorfismos da IL1beta nas doenças gástricas. Método:Realizada revisão da literatura utilizando os trabalhos recentes sobre o assunto. Considerações finais:É demonstrada a importância do envolvimento dos polimorfismos da IL1-beta nas doenças do estômago, como biomarcadores que possam ser utilizados como fatores prognósticos do desenvolvimento de câncer gástrico
