Concerns about disclosing a high-risk cervical human papillomavirus (HPV) infection to a sexual partner: a systematic review and thematic synthesis.

BACKGROUND: Human papillomavirus (HPV)-based cervical screening is now replacing cytology-based screening in several countries and many women in screening programmes will consequently receive HPV-positive results. Because of the sexually transmitted nature of HPV, receiving an HPV-positive result may raise questions about disclosing the infection to a sexual partner. OBJECTIVE: To review the quantitative and qualitative literature exploring women's concerns about disclosing a high-risk cervical HPV infection to a sexual partner. METHODS: We searched MEDLINE, PsycINFO, CINAHL Plus, Web of Science and EMBASE for studies reporting at least one disclosure-related outcome among women with high-risk HPV. We also searched the grey literature and carried out forward/backward citation searches. A narrative synthesis for quantitative studies and a thematic synthesis for qualitative studies were conducted. RESULTS: Thirteen articles met the inclusion criteria (12 qualitative, 1 quantitative). In the quantitative study, 60% of HPV-positive women felt disclosing an HPV result was 'risky'. Concerns about disclosing HPV to a sexual partner were influenced by the stigma that is associated with having an STI and uncertainty about how their partner would respond. Women questioned how, when and to whom they should disclose their HPV-positive status. CONCLUSIONS: The studies included in this review provide rich information about the range of concerns women have, the reasons for these concerns, and the questions women have about disclosing HPV to sexual partners. As studies were predominantly qualitative, the prevalence of concerns is unclear

Participant views and experiences of sexual health research: The Contraception Choices online trial

Background Online sexual health research can be convenient, efficient and low cost, but there are debates about the adequacy of online informed consent, privacy, and the acceptability of different methods of follow-up. Objectives To explore women's views and experiences of the Contraception Choices feasibility trial procedures and the place of digital interventions for contraception decision making. Methods We analysed data from two sources: (1) Qualitative interviews. Eighteen interviews were conducted with women who had taken part in the Contraception Choices pre-trial feasibility study, to evaluate recruitment and online trial procedures. (2) Free-text comments. Women in the main Contraception Choices randomised controlled trial were followed up at 3 and 6 months, and asked ‘Please tell us what you liked or disliked about the website’ and ‘Has being in the study had any good or bad effects on your life?’ A total of 387 and 414 comments were made at 3 and 6 months respectively. Data were analysed thematically. Results Participants liked being involved in a study about contraception, although recruitment from an abortion clinic was less acceptable than in other sexual health settings. Women found the trial procedures straightforward, and expressed no major concerns about online self-registration, informed consent or online data collection. Online survey questions about contraception and fertility were acceptable, and participants liked the convenience of being followed up by email or text. Conclusions Participants appreciated the advantages of the online research design and did not express concerns about consent or privacy. Women would welcome digital interventions for contraception in a variety of settings. </jats:sec

New Chiral Phases of Superfluid 3He Stabilized by Anisotropic Silica Aerogel

A rich variety of Fermi systems condense by forming bound pairs, including high temperature [1] and heavy fermion [2] superconductors, Sr2RuO4 [3], cold atomic gases [4], and superfluid 3He [5]. Some of these form exotic quantum states having non-zero orbital angular momentum. We have discovered, in the case of 3He, that anisotropic disorder, engineered from highly porous silica aerogel, stabilizes a chiral superfluid state that otherwise would not exist. Additionally, we find that the chiral axis of this state can be uniquely oriented with the application of a magnetic field perpendicular to the aerogel anisotropy axis. At suffciently low temperature we observe a sharp transition from a uniformly oriented chiral state to a disordered structure consistent with locally ordered domains, contrary to expectations for a superfluid glass phase [6].Comment: 6 pages, 4 figure, and Supplementary Informatio

The effectiveness of health coaching, home blood pressure monitoring, and home-titration in controlling hypertension among low-income patients: protocol for a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Despite the many antihypertensive medications available, two-thirds of patients with hypertension do not achieve blood pressure control. This is thought to be due to a combination of poor patient education, poor medication adherence, and "clinical inertia." The present trial evaluates an intervention consisting of health coaching, home blood pressure monitoring, and home medication titration as a method to address these three causes of poor hypertension control.</p> <p>Methods/Design</p> <p>The randomized controlled trial will include 300 patients with poorly controlled hypertension. Participants will be recruited from a primary care clinic in a teaching hospital that primarily serves low-income populations.</p> <p>An intervention group of 150 participants will receive health coaching, home blood pressure monitoring, and home-titration of antihypertensive medications during 6 months. The control group (n = 150) will receive health coaching plus home blood pressure monitoring for the same duration. A passive control group will receive usual care. Blood pressure measurements will take place at baseline, and after 6 and 12 months. The primary outcome will be change in systolic blood pressure after 6 and 12 months. Secondary outcomes measured will be change in diastolic blood pressure, adverse events, and patient and provider satisfaction.</p> <p>Discussion</p> <p>The present study is designed to assess whether the 3-pronged approach of health coaching, home blood pressure monitoring, and home medication titration can successfully improve blood pressure, and if so, whether this effect persists beyond the period of the intervention.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov identifier: NCT01013857</p

Second law, entropy production, and reversibility in thermodynamics of information

We present a pedagogical review of the fundamental concepts in thermodynamics of information, by focusing on the second law of thermodynamics and the entropy production. Especially, we discuss the relationship among thermodynamic reversibility, logical reversibility, and heat emission in the context of the Landauer principle and clarify that these three concepts are fundamentally distinct to each other. We also discuss thermodynamics of measurement and feedback control by Maxwell's demon. We clarify that the demon and the second law are indeed consistent in the measurement and the feedback processes individually, by including the mutual information to the entropy production.Comment: 43 pages, 10 figures.

Extragalactic Radio Continuum Surveys and the Transformation of Radio Astronomy

Next-generation radio surveys are about to transform radio astronomy by discovering and studying tens of millions of previously unknown radio sources. These surveys will provide new insights to understand the evolution of galaxies, measuring the evolution of the cosmic star formation rate, and rivalling traditional techniques in the measurement of fundamental cosmological parameters. By observing a new volume of observational parameter space, they are also likely to discover unexpected new phenomena. This review traces the evolution of extragalactic radio continuum surveys from the earliest days of radio astronomy to the present, and identifies the challenges that must be overcome to achieve this transformational change.Comment: To be published in Nature Astronomy 18 Sept 201

GTPase regulator associated with the focal adhesion kinase (GRAF) transcript was down-regulated in patients with myeloid malignancies

<p>Abstract</p> <p>Background</p> <p>GTPase regulator associated with the focal adhesion kinase (<it>GRAF</it>), a putative tumor suppressor gene, is found inactivated in hematopoietic malignancies by either genetic or epigenetic abnormalities. However, the expression level of <it>GRAF </it>gene has not yet been studied in leukemia. The aim of this study was to investigate the expression level of <it>GRAF </it>gene in those patients with myeloid malignancies including acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) and chronic myeloid leukemia (CML).</p> <p>Methods</p> <p>The expression levels of <it>GRAF </it>transcript were determined in 94 patients using real-time quantitative PCR (RQ-PCR). Clinical and laboratory data of these patients were collected and analyzed.</p> <p>Results</p> <p>The significantly decreased level of <it>GRAF </it>transcript was observed in three myeloid malignancies compared to controls. Within AML, there was no difference in the level of <it>GRAF </it>transcript among different FAB subtypes (<it>P </it>> 0.05). Difference was not observed in the amount of <it>GRAF </it>mRNA between CML at chronic phase and controls. As CML progressed, <it>GRAF </it>transcript significantly decreased. In MDS, three cases with 5q deletion had lower <it>GRAF </it>transcript than four without 5q deletion (median 0.76 vs 2.99) (<it>P </it>> 0.05).</p> <p>Conclusion</p> <p>our results demonstrate that the <it>GRAF </it>transcript is decreased in myeloid malignancies.</p
