    The double-edged sword of ovarian cancer information for women at increased risk who have previously taken part in screening

    Get PDF
    Background: Women at increased risk who decide not to have, or to delay, risk-reducing salpingo-oophorectomy have to rely on early diagnosis through symptom awareness and presenting to primary care as soon as possible in the absence of screening. However, little is known about the acceptability to women of this strategy. We aimed to gain an in-depth understanding of women’s perceptions and previous experiences of ovarian cancer symptom management, and the influences on ovarian cancer awareness and anticipated symptom presentation. Method: Qualitative interviews were conducted with eight women at increased risk of ovarian cancer who had previously taken part in ovarian cancer screening and analysed using interpretative phenomenological analysis (IPA). Results: Familial experience of ovarian cancer and perceived personal risk shaped women’s perceptions and behavioural responses to disease threat. Ovarian cancer information was perceived to be a double-edged sword, regarded as either useful for increasing knowledge and confidence in discussing symptom concerns with health professionals or to be avoided due to fears about cancer. Conclusion: Women may be cautious about searching for information independently and in the absence of routine ovarian screening. Practice implications: Thought needs to be given to how best to create and disseminate credible ovarian cancer symptom information materials

    Influences on anticipated time to ovarian cancer symptom presentation in women at increased risk compared to population risk of ovarian cancer

    Background In the absence of routine ovarian cancer screening, promoting help-seeking in response to ovarian symptoms is a potential route to early diagnosis. The factors influencing women’s anticipated time to presentation with potential ovarian cancer symptoms were examined. Methods Cross-sectional questionnaires were completed by a sample of women at increased familial risk (n = 283) and population risk (n = 1043) for ovarian cancer. Measures included demographic characteristics, symptom knowledge, anticipated time to symptom presentation, and health beliefs (perceived susceptibility, worry, perceived threat, confidence in symptom detection, benefits and barriers to presentation). Structural equation modelling was used to identify determinants of anticipated time to symptomatic presentation in both groups. Results Associations between health beliefs and anticipated symptom presentation differed according to risk group. In increased risk women, high perceived susceptibility (r = .35***), ovarian cancer worry (r = .98**), perceived threat (r = −.18**), confidence (r = .16**) and perceiving more benefits than barriers to presentation (r = −.34**), were statistically significant in determining earlier anticipated presentation. The pattern was the same for population risk women, except ovarian cancer worry (r = .36) and perceived threat (r = −.03) were not statistically significant determinants. Conclusions Associations between underlying health beliefs and anticipated presentation differed according to risk group. Women at population risk had higher symptom knowledge and anticipated presenting in shorter time frames than the increased risk sample. The cancer worry component of perceived threat was a unique predictor in the increased risk group. In increased risk women, the worry component of perceived threat may be more influential than susceptibility aspects in influencing early presentation behaviour, highlighting the need for ovarian symptom awareness interventions with tailored content to minimise cancer-related worry in this population

    Interventions to Promote Colorectal Cancer Screening: An Integrative Review

    Get PDF
    Behavior change interventions to promote colorectal cancer (CRC) screening have targeted people in community and primary care settings, health care providers, and health systems. Randomized controlled trials provide the strongest evidence of intervention efficacy. The purpose of this integrative review was to evaluate trials of CRC screening interventions published between 1997 and 2007 and to identify knowledge gaps and future directions for research. Thirty-three randomized trials that met inclusion criteria were evaluated using a modified version of the TREND criteria. Significant intervention effects were reported in 6 of 10 trials focused on increasing fecal occult blood testing, 4 of 7 trials focused on sigmoidoscopy or colonoscopy completion, and 9 of 16 trials focused on completion of any screening test. Several effective interventions to promote CRC screening were identified. Future trials need to use theory to guide interventions, examine moderators and mediators, consistently report results, and use comparable outcome measures

    A Pilot Study of Computerized, Tailored Intervention to Promote HPV Vaccination in Mexican-Heritage Adolescents

    This study examined feasibility, acceptability, and preliminary effects of a computer-tailored intervention aimed at promoting HPV vaccination in Mexican-heritage adolescents aged 11-17. Among 46 Mexican-heritage parents who had one or more eligible children who had not received HPV vaccines, 91% (n = 42) completed the intervention and assessments via touchscreen tablet computers in a vaccine clinic. Mean knowledge scores increased significantly from pre- to post-intervention. After the intervention, 95% (n = 40) of parents intended to get their children vaccinated; 50% (n=21) of them consented to vaccination immediately, resulting in 24 adolescents being vaccinated at that time. All parents reported learning via tablets to be easy; two nurses reported that intervention delivery in the clinic was feasible. Mean acceptability rating was high (M = 3.56, range 1 - 4). This tailored intervention proved to be feasible and acceptable, and it showed preliminary short-term effects on intent and getting the first HPV vaccine dose

    Validation of Visual Estimation of Portion Size Consumed as a Method for Estimating Food Intake by Young Indian Children

    In this observational study, estimation of food intake was evaluated using recording of portion size consumed, instead of post-weighing, as a method. In total, 930 feeding episodes were observed among 128 children aged 12–24 months in which actual intake was available by pre- and post-weighing. For each offering and feeding episode, portion size consumed was recorded by an independent nutritionist—as none, less than half, half or more, and all. Using the pre-weighed offering, available intake was estimated by multiplying portion sizes by the estimated weight. The estimated mean intake was 510.4 kilojoules compared to actual intake of 510.7 kilojoules by weighing. Similar results were found with nestum (52.0 vs 56.2 g), bread (3.8 vs 3.7 g), puffed rice (1.7 vs 1.9 g), banana (31.3 vs 24.4 g), and milk (41.6 vs 44.2 mL). Recording portion size consumed and estimating food intake from that provides a good alternative to the time-consuming and often culturally-unacceptable method of post-weighing food each time after a feeding episode

    OSPACS: Ultrasound image management system

    Get PDF
    Ultrasound scanning uses the medical imaging format, DICOM, for electronically storing the images and data associated with a particular scan. Large health care facilities typically use a picture archiving and communication system (PACS) for storing and retrieving such images. However, these systems are usually not suitable for managing large collections of anonymized ultrasound images gathered during a clinical screening trial
