BACKGROUND Postprandial glucose (PPG) and insulin responses play a role in carcinogenesis. We evaluated the association between dietary glycemic index (GI) and glycemic load (GL), markers of carbohydrate intake and PPG, and lung cancer risk in non-Hispanic whites. METHODS GL and GI were assessed among 1,905 newly diagnosed lung cancer cases recruited from the University of Texas MD Anderson C...

PURPOSE Recently, the clinical practice examination (CPX) using standardized patients has been introduced into several specialty certifying examinations in Korea. The purpose of this paper was to determine the correlation of a resident's performance on the CPX with the comprehensive written multiple-choice question (MCQ) examination on the certifying examination for family medicine. METHODS T...

The aim of this study was: 1) verify if the level of strength in young Portuguese gymnasts change according to competition levels and ranking positions; 2) compare the level of strength in finalists’ gymnasts of different competition levels; 3) identify the strength tests that discriminate the gymnasts from the different competition levels.

This study examines social and moral norms towards the intention to comply with hand hygiene among Portuguese medical students from 1st and 6th years (N = 175; 121 from the 1st year, 54 from the 6th year). The study extended the theory of planned behaviour theoretical principles and hypothesised that both subjective and moral norms will be the best predictors of 1st and 6th year medical student...

Objective: To evaluate a potential increase in the number of hypospadias cases after in utero exposure to zidovudine (ZDV) reported to the Antiretroviral Pregnancy Registry (APR), a prospective cohort study of antiretroviral-exposed pregnancies. Methods: The rate of hypospadias in male infants following first trimester exposure to ZDV-containing regimens was compared to three internal unexposed...

Dystroglycan (DG) is a cell surface glycoprotein that connects extracellular matrix molecules to the intracellular cytoskeleton, functioning as mechanical and signaling axes in various physiological events. Since the ligand-binding activity of DG strictly depends on O-mannosyl glycans attached to its extracellular α-DG subunit, aberrant glycosylation causes dystroglycanopathy, a subclass of con...

BACKGROUND Conventional methods in the diagnosis of carpal tunnel syndrome (CTS) in patients with polyneuropathy (PNP) are insufficient. AIMS We suggest that the comparison of the conduction of the median nerve with that of the neighboring peripheral nerves may be more beneficial in the diagnosis of entrapment neuropathy. SETTING AND DESIGN The median nerve sensory conduction in healthy vol...

OBJECTIVE In this study, we measured the cortical bone thickness in the mandibular buccal and lingual areas using computed tomography in order to evaluate the suitability of these areas for application of temporary anchorage devices (TADs) and to suggest a clinical guide for TADs. METHODS The buccal and lingual cortical bone thickness was measured in 15 men and 15 women. Bone thickness was me...

BACKGROUND Arsenic has immunomodulatory properties and may have the potential to alter susceptibility to infection in humans. OBJECTIVES We aimed to assess the relation of arsenic exposure during pregnancy with immune function and hepatitis E virus (HEV) infection, defined as seroconversion during pregnancy and postpartum. METHODS We assessed IgG seroconversion to HEV between 1st and 3rd tr...
