    The objective of this study was to investigate whether malnourished autopsied adults would present higher frequency of pneumonitis than non-malnourished ones would. All of the autopsied adults (n = 175; age > 18 years) with complete records, including weight and height data, were included. Pneumonitis was observed more frequently in malnourished individuals (59.1%) than in non-malnourished individuals (41.3%). This study showed that the percentage of pneumonitis among autopsied adults was high, in addition to an increased risk of pneumonitis among these individuals.O objetivo deste estudo foi verificar se adultos subnutridos autopsiados teriam maior freqĂŒĂȘncia de pneumonite que adultos nĂŁo-subnutridos.

    Introduction Ovarian cancer has a high mortality and delayed diagnosis. Inflammation is a risk factor for ovarian cancer, and the inflammatory response is involved in almost all stages of tumor development. Immunohistochemical staining in stroma and epithelium of a panel of cytokines in benign and malignant ovarian neoplasm was evaluated. In addition, immunostaining was related to prognostic factors in malignant tumors. Method The study group comprised 28 ovarian benign neoplasias and 28 ovarian malignant neoplasms. A panel of cytokines was evaluated by immunohistochemistry (Th1: IL-2 and IL-8; Th2: IL-5, IL-6, and IL-10; and TNFR1). Chi-square test with Yates’ correction was used, which was considered significant if less than 0.05. Results TNFR1, IL-5, and IL-10 had more frequent immunostaining 2/3 in benign neoplasms compared with malignant tumors. Malignant tumors had more frequent immunostaining 2/3 for IL-2 in relation to benign tumors. The immunostaining 0/1 of IL 8 was more frequent in the stroma of benign neoplasms compared with malignant neoplasms. Evaluation of the ovarian cancer stroma showed that histological grade 3 was significantly correlated with staining 2/3 for IL-2 ( P = 0.004). Women whose disease-free survival was less than 2.5 years had TNFR1 stromal staining 2/3 ( P = 0.03) more frequently. Conclusion IL-2 and TNFR1 stromal immunostaining are related prognostic factors in ovarian cancer and can be the target of new therapeutic strategies

    The objectives of this study were to investigate the immunohistochemical expression of markers of mast cells and M2 macrophages in benign and malignant ovarian neoplasms and to examine the prognostic value of this expression in ovarian cancer. The study was performed with samples from 32 patients, divided into benign (n = 16) and malignant (n = 16) neoplasm groups. Samples obtained by surgical resection were submitted to immunohistochemical analysis. Higher proportions of M2 macrophages (p = .041) and mast cells (p = .0054) were present in malignant than benign ovarian neoplasms. Histological grade 2/3 was related to higher proportions of M2 macrophages compared with grade 1 (p = .0102). Stages II-IV were also related to higher proportions of M2 macrophages (p = .0102). Logistic regression revealed that M2 macrophages predicted malignancy [odds ratio (OR) = 1.017; 95% confidence interval (CI), 1.003–1.037; p = .017], but that mastocytes had greater predictive value for this outcome (OR = 1.127; 95% CI, 1.018–1.105; p = .013). M2 macrophages predicted more advanced histological grades (OR = 1.060; 95% CI, 1.010–1.218; p = .003). The proportions of M2 macrophages and mast cells were greater in malignant than in benign ovarian neoplasms. Larger proportions of cells expressing M2 macrophages were related to more advanced histological grades and disease stages, and thus to worse prognoses for ovarian cancer.Impact Statement What is already known on this subject? Concentrations of mast cells and M2 macrophages have been observed in several tumour types, but their significance remains uncertain. What do the results of this study add? The proportions of M2 macrophages and mast cells were greater in malignant than in benign ovarian neoplasms. Larger proportions of cells expressing M2 macrophages were related to higher histological grades and more advanced stages of the disease. What are the implications of these findings for clinical practice and/or further research? Larger proportions of cells expressing M2 macrophages were related to worse prognoses for malignant ovarian neoplasia. The discovery of new prognostic factors in ovarian cancer may be the target of studies on new treatments and immunotherapies for this disease. In addition, it can help guide the oncologist towards more aggressive treatments for patients with worse prognostic factors

    <div><p>Abstract Ovarian cancer is the leading cause of death among gynecologic tumors because in most of the cases (75%), the disease is diagnosed in advanced stages. Screening methods are not available since the disease is rare, and the tested methods, such as ultrasound and CA125, were not able to decrease the mortality rate for this type of cancer. This article discusses the main risk factors for ovarian cancer, and the potential clinical and surgical strategies for the prevention of this disease.</p></div

    Differences in Stromal Immunostaining of Tumour Necrosis Factor-alpha and its Receptors in Neoplastic and Non Neoplastic Ovarian Lesions: A Cross-sectional Study

    No full text
    Introduction: Ovarian cancer has an unknown pathogenesis, and cytokines may play an important role in the aetiology and prognosis. Tumour Necrosis Factor-alpha (TNF-α) and its receptors (TNFR1 and TNFR2) are involved in the biology of ovarian cancer, tumour pathogenesis, and their relationship with prognostic factors. They are involved in biological processes such as immunoregulation, growth modulation, and cell differentiation. Aim: To evaluate stromal immunostaining of TNF-α and its receptors (TNFR1 and TNFR2) in malignant ovarian neoplasms, comparing it with benign ovarian neoplasms and non neoplastic ovarian lesions. Materials and Methods: A cross-sectional study was carried out at the Department of Gynaecology and Obstetrics, Federal University of TriĂąngulo Mineiro, Uberaba, Minas Gerais, Brazil, from January 1997 to December 2020. Patients with ovarian lesions who underwent surgical treatment according to pre-established criteria (n=95) were included in the study. Patients with benign (n=37) and malignant (n=43) ovarian epithelial neoplasms, and non neoplastic ovarian lesions (n=15) were included. Data evaluated included age, parity, hormonal status (menarche or menopause), histological grade, and staging. Immunohistochemical study was performed to evaluate stromal TNF-α, TNFR1, and TNFR2. Data were analysed by GraphPad Prism 6 and IBM Statistical Package for the Social Sciences (SPSS) Statistics 20.0 software. The comparison between non neoplastic tumours, benign and malignant neoplasms was performed by the Fisher’s exact test with a significance level below 0.05. Results: Considering staining intensity 0 and 1 as “weak immunostaining” and 2 and 3 as “strong immunostaining,” TNF-α stromal immunostaining was stronger (2/3) in benign ovarian neoplasms compared to non neoplastic tumours (p-value=0.0016) and in malignant neoplasms compared to non neoplastic tumours (p-value<0.0001). TNFR1 immunostaining was stronger (2/3) in the stroma of malignant neoplasms compared to benign neoplasms (p-value<0.0001) and stronger (2/3) when comparing benign neoplasms with non neoplastic ovarian lesions (p-value=0.0002). For TNFR2, stromal immunostaining was stronger (2/3) in malignant neoplasms compared to benign neoplasms (p-value =0.0091) and stronger in malignant neoplasms compared to non neoplastic lesions (p-value=0.0004). Conclusion: A stronger immunostaining for TNF-α and its receptors was found in ovarian cancer, suggesting that they may be targets for further studies to verify their role in carcinogenesis and the progression of ovarian neoplasms. A better understanding of the role of TNF-α and its receptors in the tumour stroma of ovarian tumours may lead to future studies that may clarify the mechanisms of carcinogenesis and tumour progression

    Avaliar a flexibilidade da cadeia muscular posterior, utilizando o mĂ©todo proposto por Wells e Dillon, antes e apĂłs cada sessĂŁo de hidroterapia. Foi verificada a flexibilidade de trĂȘs crianças com Paralisia Cerebral (PC) diparĂ©ticas, com idades entre sete a dez anos. Os valores de flexibilidade foram aferidos, utilizando o FlexĂŽmetro de Wells. Houve aumento significativo da flexibilidade da cadeia muscular posterior dos pacientes apĂłs cada sessĂŁo de hidroterapia, tanto na avaliação em grupo quanto individual, assim como antes da primeira sessĂŁo de hidroterapia quando comparada com a Ășltima. O estudo sugere que a hidroterapia promove melhora da flexibilidade em relação Ă  cadeia muscular posterior de crianças com PC diparĂ©ticas, pelo relaxamento global e consequente diminuição dotĂŽnus muscular, quando associada a exercĂ­cios de alongamentos passivos. To evaluate the flexibility of the posterior muscle chain using the method proposed by Wells and Dillon, before and after each hydrotherapy session. The study verified the flexibility of three children with diplegic cerebral palsy (CP), aged 7 to 10. The values of flexibility were measured using the Wells’ Flexometer. There was a significant increase in the flexibility of posterior muscle chain of the patients after each session of hydrotherapy, both in the individual evaluation and in the group, as well as before the first session of hydrotherapy compared to the last. The study suggests that hydrotherapy promotes the improvement of flexibility, by relaxation of muscle tone of children with diplegic CP, in relation to the posterior muscle chain, when combined with passive stretching exercises
