Among the available treatments for MetS in adolescents, behavioral interventions such as increasing physical activity (PA) are preferred. This study aimed to investigate the association of PA and sitting time with MetS and a complete set of metabolic health parameters.

Perceptions of the oral health of their patients reported by Brazilian medical residents in psychiatry.

Persons with severe mental disorders have higher chances of presenting oral health problems than persons in the general population. Mental disorders are considered public-health problems worldwide. Interpreting statements on oral health made by medical students receiving instruction in psychiatry is essential to provide elements for reflection on their difficulties, barriers or limited knowledge in managing their patients' oral health.

Analysis of morbidity and mortality in patients with primary bone tumors who underwent sacrectomy: A systematic review.

Background: Sacrectomy is indicated for the resection of life-threatening tumors in the sacrum area. Several studies have been conducted to investigate important aspects of sacrectomy to help reduce the morbidity and mortality of patients who underwent the procedure. This aim of this systematic review was to highlight the prognoses of patients who underwent sacrectomy for the resection of primary bone tumors by analyzing information related to the intraoperative and perioperative periods of the procedure.

Patients with Schizophrenia Undergoing Gastric Bypass Surgery: a Case Series Study.

Purpose: Obesity affects approximately 45-55% of persons with schizophrenia and is more difficult to manage in these individuals than in the general population, apart from being an additional factor for morbidity and premature mortality. Although bariatric surgery is considered the most effective long-term treatment for severe obesity, there are few reports on the outcomes of this procedure in persons with schizophrenia. This study aimed to evaluate weight loss and psychiatric symptoms in persons with obesity and schizophrenia after bariatric surgery.

Epstein-Barr virus induces morphological and molecular changes in thyroid neoplastic cells.

Although the evolution of differentiated thyroid cancer (DTC) is usually indolent, some tumors grow fast, metastasize, and may be fatal. Viruses have been associated with many human tumors, especially the Epstein-Barr virus (EBV), which shows a high viral load in DTC. In order to evaluate the ability of the virus to cause morphological and molecular changes in neoplastic thyroid cell lines TPC-1, BCPAP, and 8505C, a viral adaptation was performed for the analysis of EBV cytopathic effect (CPE), viral kinetics and gene expression analysis of oncogenes KRAS, NRAS, HRAS, and TP53.

Thyroid autoimmune diseases and thyroid tumors: Would EBV infection be the link?

The role of EBV in thyroid cancer development and the patient's outcome is still unclear. Using nested-PCR, Moghoofei et al. reported a high incidence of a virus in thyroid tumor samples, different from our results, obtained by quantitative real-time PCR and confirmed by in situ hybridization.

Otitis Media: Long-Term Effect on Central Auditory Nervous System.

Objectives: To analyze the central auditory nervous system function through behavioral and electrophysiological tests in children with a history of otitis media and subsequent bilateral tubes placement surgery.

Methods: The participants were divided into two groups between eight and 14 years old: control group (CG) consisted of 40 children with no history of otitis media; experimental group (EG) consisted of 50 children with documented history of otitis media and undertook a surgery for bilateral tubes placement. All children completed audiological evaluation (audiometry, speech audiometry, and immittance audiometry), behavioral evaluation (tests: dichotic digits, synthetic sentence identification with ipsilateral competing message, gaps-in-noise, frequency pattern), and electrophysiological evaluation (Auditory Brainstem Response, ABR, Frequency Following Response, FFR (verbal), and Long Latency Auditory Evoked Potential, LLAEP).

Epstein-Barr Virus and Thyroid Cancer.

Epstein-Barr virus (EBV) seroprevalence is extremely high worldwide. This member of the herpesvirus family is considered to be a human carcinogen, implicated in lymphoid and epithelial malignancies. Because of its characteristics, EBV has been investigated in thyroid specimens, especially in autoimmune and neoplastic lesions.

TISSUE EXPRESION OF THE GENES MUTYH AND OGG1 IN PATIENTS WITH SPORADIC COLORECTAL CANCER.

Background: MTUYH and OGG1 genes have importance in the base excision repair systems of oxidized DNA bases. Modification of the tissue expression of these genes is related to the increased risk of developing colorectal cancer.

Aim: To evaluate the tissue expression of MUTYH and OGG1 comparing normal and neoplastic tissues of patients with sporadic colorectal cancer and to correlate it with clinical and histopathological variables.

Detection of Putative Stem-cell Markers in Invasive Ductal Carcinoma of the Breast by Immunohistochemistry: Does It Improve Prognostic/Predictive Assessments?

Introduction: Experimental evidences from the last 2 decades supports the existence of a special type of neoplastic cell with stem-like features [cancer stem cell (CSC)] and their role in the pathophysiology and therapeutic resistance of breast cancer. However, their clinical value in human breast cancer has not been fully determined.

Materials And Methods: An immunohistochemistry panel of 10 putative CSC markers (CD34, C-KIT, CD10, SOX-2, OCT 3/4, p63, CD24, CD44, CD133, and ESA/EPCAM) was applied to 74 cases of breast cancer, followed in a Regional Cancer Center of Minas Gerais State, Brazil, from 2004 to 2006.

Comparison of auditory event-related potentials between children with benign childhood epilepsy with centrotemporal spikes and children with temporal lobe epilepsy.

The abnormal brain discharges observed in benign childhood epilepsy with centrotemporal spikes (BECTS) and temporal lobe epilepsy (TLE) are located close to areas responsible for auditory and language processing. This study aimed to analyze the results of auditory event-related potentials (P300) in children with BECTS and TLE in order to assess whether the epileptic activity in centrotemporal and temporal regions may compromise the integrity and physiology of auditory system structures. This was a prospective, comparative, and cross-sectional study.

Temporal auditory processing and phonological awareness in children with benign epilepsy with centrotemporal spikes.

The aim of this research was to analyze temporal auditory processing and phonological awareness in school-age children with benign childhood epilepsy with centrotemporal spikes (BECTS).
