Although sexual minority women are at risk of sexually transmitted infections (STIs) and cervical cancer, few nationally representative studies have assessed sexual orientation disparities in sexual health care among women. Using data from the 2011-2013 and 2013-2015 waves of the National Survey of Family Growth, which provide a national probability sample of U.S. women aged 15-44years (N=11.300), we used multivariable logistic regression to examine the associations between sexual behavior and sexual identity (modeled separately) and STI testing in the past year, Pap test use in the last 3years, lifetime HIV testing, and lifetime human papillomavirus (HPV) testing...

Inappropriate cervical cancer screening (e.g., screening too often) can result in unnecessary medical procedures, treatment, and psychological distress. To balance the benefits and harms, cervical cancer screening guidelines were recently modified in favor of less frequent screening (i.e., every 3 to 5 years). This study investigated women's acceptance of less frequent cervical cancer screening and their primary concerns about extending the screening interval beyond one year. A national sample of 376 U.S. women ages 21-65 completed an online survey in 2014...

A prior conditioning resistance exercise can augment subsequent performance of the affected muscles due to the effects of post-activation potentiation (PAP). The non-local muscle fatigue literature has illustrated the global neural effects of unilateral fatigue. However, no studies have examined the possibility of acute non-local performance enhancements. The objective of the study was to provide a conditioning stimulus in an attempt to potentiate the subsequent jump performance of the affected limb and determine if there were performance changes in the contralateral limb...

BACKGROUND: Persistent high-risk human papillomavirus (HPV) infection is a necessary prerequisite for development of cervical cancer and its precursor lesion, high-grade squamous intraepithelial lesion (HSIL). However, HPV infection is not sufficient to drive this process, and genetic and environmental factors may also play a role. METHODS/DESIGN: The Cervical Cancer, Genetics and Environment Twin Study was established to investigate the environmental and genetic influences on variation in susceptibility to cervical pre-cancer in 25- to 69-year-old monozygotic (MZ) and dizygotic (DZ) twins recruited through the Australian Twin Registry...

Pulmonary arterial pressure (PAP) is an indicator trait for pulmonary hypertension and for the risk of developing high-altitude disease (HAD) in cattle. Pulmonary arterial pressures provide a tool for selection of breeding cattle for tolerance to high altitude in mountainous regions of the United States. The objective of this study was to evaluate relationships between growth performance traits and yearling PAP (42.4 ± 9.9 mmHg; = 5,776; elevation 2,150 m) using data from 1993 to 2014 in the John E. Rouse Colorado State University Beef Improvement Center (CSU-BIC) Angus herd...

Human papillomavirus (HPV) has been identified as the leading cause of cervical cancer. While HPV risk factors have been well studied, less is known about those with HPV and their perceptions about health ramifications. The purposes of this study were to examine unmarried college student women's (1) HPV diagnosis status and (2) perceived risk of getting cervical cancer in the next 5 years. Data were analyzed from 1106 unmarried, sexually active college women aged 18 to 26. Binary logistic regression compared HPV-related knowledge, vaccination-related perceptions, mandate support, healthcare utilization, sexual behaviors, and personal characteristics...

Cervical cancer screening based on the Papanicolaou (Pap) test is a widely applied but not always efficient practice for detecting Human Papillomavirus (HPV) mediated lesions, partially due to a non-systematic and inadequate screening process. Our aim was to introduce an inexpensive easy-to-use direct screening platform for improved detection of abnormal cells indicative of underlying cervical neoplasia as well as persisting HPV infection. By employing a novel, efficient technique of laser-based micromachining, we achieved the fabrication of spatial grids on commercially available coverslips allowing visual segmentation of the slide for efficient screening...

INTRODUCTION: Malignant transformation of the Potentially Malignant Lesions (PML) in the oral cavity is associated with elevated mortality rate because of its aggressive and exceedingly invasive nature. Meticulous diagnosis and prompt therapy of PML may help prevent malignant conversion in oral lesions. Carcinogenic insult to oral cells results in chromosomal damage and formation of Micronuclei (Mn), before the development of clinical symptoms. AIM: To determine the genotoxic effect of smoking and chewing tobacco on target tissue using Mn assay and to evaluate the prevalence of other nuclear anomalies associated with it and to determine the reliability of feulgen stain for Mn assay over Papaincolau (PAP) stain...

In patients with systemic sclerosis, a ratio between forced vital capacity (FVC) and diffusing capacity of carbon monoxide (DLCO, FCV%/DLCO%) >1.5 might be a predictor of pulmonary hypertension (PH). The aim of this study is, therefore, to evaluate whether this index can be used in patients with PH, regardless of etiology. 83 consecutive outpatients with suspected PH at non-invasive work-up underwent spirometry and DLCO test before right heart catheterization (RHC); FVC%/DLCO% ratio was then calculated and compared with mean pulmonary-artery-pressure (mPAP) and mortality at 5-year follow-up...
