    ER PvuII and XbaI polymorphisms in postmenopausal women with posterior tibial tendon dysfunction: a case control study
    BackgroundPosterior tibial tendon (PTT) insufficiency is considered as the main cause of adult acquired flat foot and is three times more frequent in females. High estrogen levels exert a positive effect on the overall collagen synthesis in tendons. We have previously demonstrated the association between some genetic single-nucleotide polymorphism (SNP) and tendinopathy. In the present study, we investigated the association of PvuII c454-397T>C (NCBI ID: rs2234693) and XbaI c454-351A>G (NCBI ID: rs9340799) SNPs in estrogen receptor alfa (ER-) gene with PPT dysfunction.MethodsA total of 92 female subjects with PTT dysfunction, with histopathological examination of the tendon and magnetic resonance image (MRI) evidence of tendinopathy, were compared to 92 asymptomatic females who presented an intact PPT at MRI for PvuII and XbaI SNPs in the ER- gene. Genomic DNA was extracted from saliva and genotypes were obtained by polymerase chain reaction restriction fragment length polymorphism.ResultsThe analysis of PvuII SNPs showed no significant differences in the frequency of alleles and genotypes between control and PTT dysfunction groups. The XbaI SNPs in the ER- gene showed significant differences in the frequency of genotypes between control and test groups (p=0.01; OR 95% 1.14 (0.55-2.33).ConclusionsThe XbaI SNP in the ER gene may contribute to tendinopathy, and the A/A genotype could be a risk factor for PTT tendinopathy in this population. The PvuII SNP studied was not associated with PTT tendinopathy.

    Dietary intake and menopausal symptoms in postmenopausal women: a systematic review
    Despite literature pointing to a relation between dietary intake and menopausal symptoms, most studies have evaluated either only supplements or only specific nutrients or foods. Therefore, this study aimed to provide a systematic review of the literature regarding the association between dietary intake and menopausal symptoms in postmenopausal women. A systematic search was conducted across PubMed/Medline, Web of Science, Scopus, and Embase to identify studies published between 2009 and 2019. We identified 3828 studies; after screening, 73 studies were reviewed and 19 of these investigated nutrient and food intake and eating patterns associated with the intensity of menopausal symptoms. Studies evaluating diet quality or dietary patterns showed an association between lower intensity of psychological symptoms, sleep disorders, and vasomotor, urogenital, and somatic symptoms and higher consumption of vegetables, whole grains, and unprocessed foods. Also, the intensity of these symptoms is associated with high-processed foods, saturated fats, and sugars. Regarding nutrient and/or specific food, the studies indicated an association between caffeine intake and type of fat intake and the intensity of menopausal symptoms. Dietary intake was found to be associated with the severity of menopausal symptoms; however, evidence for the association between dietary intake and menopausal symptoms is inconsistent and inconclusive, and is provided by a small number of studies.

    Evaluation of the accuracy of mammography, ultra-sound and magnetic resonance imaging in suspect breast lesions
    (2020) PEREIRA, Renato de Oliveira; LUZ, Larissa Almondes da; CHAGAS, Diego Cipriano; AMORIM, Jefferson Rodrigues; NERY-JUNIOR, Elmo de Jesus; ALVES, Araci Castelo Branco Rodrigues; ABREU-NETO, Flavio Teixeira de; OLIVEIRA, Maria da Conceicao Barros; SILVA, Danylo Rafhael Costa; SOARES-JUNIOR, Jose Maria; SILVA, Benedito Borges da
    OBJECTIVES: In breast cancer diagnosis, mammography (MMG), ultrasonography (USG) and magnetic resonance imaging (MRI) are the imaging methods most used. There is a scarcity of comparative studies that evaluate the accuracy of these methods in the diagnosis of breast cancer. METHODS: A cross-sectional study was carried out through the review of electronic medical records of 32 female patients who underwent breast imaging examinations at a imaging diagnostic center in Teresina, State of Piaui, Brazil. Patients who had these three imaging methods at the time of the evaluation of the same nodule were included. The nodule must have been classified as suspect by the BI-RADS (R) system in at least one of the methods. Data from each method were compared with the histopathological examination. Statistical analysis used the calculation of proportions in Excel 2010. RESULTS: MMG showed 56.2%, 87.5%, 81.8%, 66.7% and 71.8% of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy, respectively. USG had 75%, 18.8%, 48%, 42.8% and 46.9% of sensitivity, specificity, PPV, NPV and accuracy, respectively. In turn, MRI had 100%, 50%, 66.7%, 100% and 75% of sensitivity, specificity, PPV, NPV and accuracy, respectively. CONCLUSION: Thus, MRI and MMG were more accurate in evaluating suspicious breast lumps. MRI had a low specificity, mainly to high breast density, while MMG had also sensitivity limited due to high breast density and USG has been proven to be useful in these patients.

    Hyperprolactinemia modifies extracellular matrix components associated with collagen fibrillogenesis in harderian glands of non- and pregnant female mice
    (2023) ARAUJO, Ariadne S. L.; SIMOES, Manuel de J.; JR, Osvaldo P. Araujo; SIMOES, Ricardo S.; BARACAT, Edmund C.; NADER, Helena B.; JR, Jose M. Soares; GOMES, Regina C. T.
    The harderian gland (HG) is a gland located at the base of the nictating membrane and fills the inferomedial aspect of the orbit in rodents. It is under the influence of the hypothalamic-pituitary-gonadal axis and, because of its hormone receptors, it is a target tissue for prolactin (PRL) and sex steroid hormones (estrogen and progesterone). In humans and murine, the anterior surface of the eyes is protected by a tear film synthesized by glands associated with the eye. In order to understand the endocrine changes caused by hyperprolactinemia in the glands responsible for the formation of the tear film, we used an animal model with metoclopramide-induced hyperprolactinemia (HPRL). Given the evidences that HPRL can lead to a process of cell death and tissue fibrosis, the protein expression of small leucine-rich proteoglycans (SLRPs) was analyzed through immunohistochemistry in the HG of the non-and the pregnant female mice with hyperprolactinemia. The SRLPs are related to collagen fibrillogenesis and they participate in pro-apoptotic signals. Our data revealed that high prolactin levels and changes in steroid hormones (estrogen and progesterone) can lead to an alteration in the amount of collagen, and in the structure of type I and III collagen fibers through changes in the amounts of lumican and decorin, which are responsible for collagen fibrillogenesis. This fact can lead to the impaired functioning of the HG by excessive apoptosis in the HG of the non-and the pregnant female mice with HPRL and especially in the HG of pregnancy-associated hyperprolactinemia.
