BACKGROUND: Oscillations, action, and postsynaptic potentials in glial-neuronal ensembles integrate the spectral power (SP) of electroencephalographic (EEG). Our objective is to propose SP indicators of healthy brains (control groups) based on the default mode and their modifications by habituation and visual-motor association (VM-asso), to support diagnostic and rehabilitation processes. However, important differences seem to exist between men and women. Therefore, we aim to analyze EEG characteristics in a female sample...

Although the production of antigen-specific antibodies has been the originally accepted function of B-cells during immune responses, specific subsets that can negatively regulate inflammation, designated regulatory B-cells (Bregs), have been identified recently. These immunosuppressive cells support tolerance, mainly through the production of interleukin 10 and other unconventional factors. There have been emerging data suggesting their importance in diverse normal and pathologic processes. Novel and in development B-cell targeted therapies seem to be ideal treatments for different types of diseasessuch as cancer and allergy...

The prevalence of interstitial lung disease in patients with rheumatoid arthritis varies from 10 to 42%. Rheumatoid arthritis patients with interstitial lung disease have three times the risk of death compared with those without the disease. Prognosis seems to be related to the high-resolution computed tomography pattern. Usual interstitial pneumonia pattern, resembling idiopathic pulmonary fibrosis, carries a worse prognosis. Validated strategies to identify different phenotypes and assess the disease activity in rheumatoid arthritis interstitial lung disease are lacking...

BACKGROUND: Young women with breast cancer (YWBC) comprise a group of patients with unique biopsychosocial characteristics with a special perception of needs throughout their disease and survivorship. Contexts marked by restricted allocations and economic constraints might further aggravate the struggle of these patients living within limited resource settings and can demand added requirements for them and their families. OBJECTIVE: To analytically explore the existing knowledge regarding the needs of YWBC in low- and middle- income countries (LMICs)...

Young women with breast cancer have age-specific concerns regarding changes in sexuality, fertility, and body image. However, the psychological impact of BC and its treatments is not exclusive to young patients and it also affects their social context, especially their partners, as they experience higher illness intrusiveness than the partners of older women. In young BC patients, relationships, body image, and sexual problems are related to most quality of life domains. While BC treatment is being planned, all women should be informed about the possible side-effects of treatment on sexuality, fertility, and body image...

The incidence of breast cancer (BC) is rising worldwide, with an increase in aggressive neoplasias in young women. Traditionally, BC in young women has been thought to be etiologically driven, primarily by genetic/hereditary factors. However, these factors explain only a small proportion of BCs, pointing to a role of the environment. Suspected factors responsible for this increase include lifestyle changes, notably alcohol consumption, diet with high intake of refined carbohydrates and saturated fat and low intake of polyunsaturated fatty acids (PUFA), fiber and vitamins (such as folate, vitamin D, and carotenoids), low physical activity, and body fatness, all of which may act from childhood and adolescent years through adulthood...

Young women with breast cancer (YWBC) represent roughly 15% of breast cancer (BC) cases in Latin America and other developing regions. Breast tumors occurring at an early age are more aggressive and have an overall worse prognosis compared to breast tumors in postmenopausal women. The expression of relevant proliferation biomarkers such as endocrine receptors and human epidermal growth factor receptor 2 appears to be unique in YWBC. Moreover, histopathological, molecular, genetic, and genomic studies have shown that YWBC exhibit a higher frequency of aggressive subtypes, differential tumor gene expression, increased genetic susceptibility, and specific genomic signatures, compared to older women with BC...

Young women with breast cancer (BC) are a special population with distinctive genetic, clinical, and psychosocial features and requirements based on at least three considerations: (1) Cancer presentation at young age is often diagnosed at advanced stages, hence its prognosis is worse compared to their older counterparts1,2; (2) young BC patients often receive aggressive and prolonged systemic treatments that can be associated with significant long-term morbidity3; and (3) young women with BC experience substantial psychosocial vulnerability resulting from high levels of distress and depression associated with oncological interventions4...

There is ongoing debate concerning non-nutritive sweeteners, their usage, and their effects on metabolism. The association between non-nutritive sweeteners consumption, development of metabolic diseases, and changes in appetite-regulating hormones is not clear. The aim of this article is to present an overview of non-nutritive sweeteners and to examine the scientific evidence of their effects on glucose metabolism and appetite-regulating hormones. Some observational studies suggest an association between non-nutritive sweeteners consumption and development of metabolic diseases; however, adiposity is a confounder frequently found in these studies...
