Evaluation of extension of breast screening to women aged 65–70 in England using screening performance measures
The objective of this study was to investigate screening performance measures in the English screening units that began inviting women aged 65–70 between 1 April 2001 and 1 April 2004. We analysed results after each unit commenced inviting women aged 65–70. In addition, we analysed data from units that invited this age group for a second time between 1 April 2004 and 31 March 2007. Results for women aged 65–70 were compared to women aged 50–64 and 60–64. Average uptake was 72.8% for women aged 65–70 and 76.7% for women aged 50–64. For women screened within the last 5 years, uptake was 88.7% for older women and 89.1% for younger women. For women previously screened within 5 years the invasive cancer detection rate was 17% higher in the 65–70 age group than in the 60–64 age group. The rates of recall to assessment and PPV were 3.5 and 27.6% in women aged 65–70 and 3.4 and 24.6% in women aged 50–64 respectively. These results suggest that, as in the earlier demonstration studies, uptake rates remain high in older women, and many more older women attend following an invitation than had previously self-referred. The cancer detection rate is higher in this older age group, whereas rates of recall are generally similar to those in younger women; consequently the PPV is also higher in older women
Impact of NHS breast screening on advanced disease and mortality from breast cancer in the North West of England
Factors associated with the utilization of community dental services among newly incarcerated adults
Background: Given the high rates of risky behaviors and health conditions among incarcerated individuals and the relationship between oral and general health, receipt of quality dental care is essential to the overall health and well-being of this population. However, few recent studies have focused on access to care and the state of oral health among incarcerated populations in the U.S. For the current study, a secondary data analysis was conducted to: 1) assess factors associated with the use of dental services among a newly incarcerated prison population in Georgia and 2) consider barriers related to utilization of dental services pre- to post-release.
Methods: Descriptive statistics were calculated, and bivariate and logistic regression analyses were conducted utilizing SAS 9.2 software. Results: Thirty-one percent (n=250) of survey respondents reported having a dental visit within the past year. Survey respondents who had a regular dentist (OR: 1.9; 95% CI: 1.325, 2.697), private dental insurance (OR: 1.5; 95% CI: 1.022, 2.245), or who reported pain as the reason for their last dental visit (OR: 2.2; 95% CI: 1.556, 3.130) were more likely to have utilized dental services within the past year.
Conclusions: The findings highlight the role of social and economic resources and oral health needs on utilization of dental services. Additional practice and policy efforts are needed to address gaps in the dental care continuum that affect currently and formerly incarcerated adults in Georgia
Progesterone-dependent induction of phospholipase C-related catalytically inactive protein 1 (PRIP-1) in decidualizing human endometrial stromal cells
Decidualization denotes the transformation of endometrial stromal cells into specialized decidual cells. In pregnancy, decidual cells form a protective matrix around the implanting embryo, enabling coordinated trophoblast invasion and formation of a functional placenta. Continuous progesterone (P4) signaling renders decidual cells resistant to various environmental stressors, whereas withdrawal inevitably triggers tissue breakdown and menstruation or miscarriage. Here, we show that PLCL1, coding phospholipase C (PLC)-related catalytically inactive protein 1 (PRIP-1), is highly induced in response to P4 signaling in decidualizing human endometrial stromal cells (HESCs). Knockdown experiments in undifferentiated HESCs revealed that PRIP-1 maintains basal phosphoinositide 3-kinase/Protein kinase B activity, which in turn prevents illicit nuclear translocation of the transcription factor forkhead box protein O1 and induction of the apoptotic activator BIM. By contrast, loss of this scaffold protein did not compromise survival of decidual cells. PRIP-1 knockdown did also not interfere with the responsiveness of HESCs to deciduogenic cues, although the overall expression of differentiation markers, such as PRL, IGFBP1, and WNT4, was blunted. Finally, we show that PRIP-1 in decidual cells uncouples PLC activation from intracellular Ca2+ release by attenuating inositol 1,4,5-trisphosphate signaling. In summary, PRIP-1 is a multifaceted P4-inducible scaffold protein that gates the activity of major signal transduction pathways in the endometrium. It prevents apoptosis of proliferating stromal cells and contributes to the relative autonomy of decidual cells by silencing PLC signaling downstream of Gq protein-coupled receptors
Towards understanding the myometrial physiome: approaches for the construction of a virtual physiological uterus
Premature labour (PTL) is the single most significant factor contributing to neonatal morbidity in Europe with enormous attendant healthcare and social costs. Consequently, it remains a major challenge to alleviate the cause and impact of this condition. Our ability to improve the diagnosis and treatment of women most at risk of PTL is, however, actually hampered by an incomplete understanding of the ways in which the functions of the uterine myocyte are integrated to effect an appropriate biological response at the multicellular whole organ system. The level of organization required to co-ordinate labouring uterine contractile effort in time and space can be considered immense. There is a multitude of what might be considered mini-systems involved, each with their own regulatory feedback cycles, yet they each, in turn, will influence the behaviour of a related system. These include, but are not exclusive to, gestational-dependent regulation of transcription, translation, post-translational modifications, intracellular signaling dynamics, cell morphology, intercellular communication and tissue level morphology.
We propose that in order to comprehend how these mini-systems integrate to facilitate uterine contraction during labour (preterm or term) we must, in concert with biological experimentation, construct detailed mathematical descriptions of our findings. This serves three purposes: firstly, providing a quantitative description of series of complex observations; secondly, proferring a database platform that informs further testable experimentation; thirdly, advancing towards the establishment of a virtual physiological uterus and in silico clinical diagnosis and treatment of PTL

Disability and participation in breast and bowel cancer screening in England: a large prospective study.
BACKGROUND: There is limited information about participation in organised population-wide screening programmes by people with disabilities. METHODS: Data from the National Health Service routine screening programmes in England were linked to information on disability reported by the Million Women Study cohort participants. RESULTS: Of the 473 185 women offered routine breast or bowel cancer screening, 23% reported some disability. Women with disabilities were less likely than other women to participate in breast cancer screening (RR=0.64, 95% CI: 0.62-0.65) and in bowel cancer screening (RR=0.75, 0.73-0.76). Difficulties with self-care or vision were associated with the greatest reduction in screening participation. CONCLUSION: Participation in routine cancer screening programmes in England is reduced in people with disabilities and participation varies by type of disability
Comparison of two methods to identify live benthic foraminifera : a test between Rose Bengal and CellTracker Green with implications for stable isotope paleoreconstructions
Author Posting. © American Geophysical Union, 2006. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Paleoceanography, 21 (2006): PA4210, doi:10.1029/2006PA001290.The conventional method to distinguish live from dead benthic foraminifers uses Rose
Bengal, a stain that reacts with both live and dead cytoplasm. CellTracker Green CMFDA is a
fluorogenic probe causing live cells to fluoresce after proper incubation. To determine the more
accurate viability method, we conducted a direct comparison of Rose Bengal staining with
CellTracker Green labeling. Eight multicore tops were analyzed from Florida Margin (SE
United States; 248-751 m water depths), near Great Bahama Bank (259-766 m), and off the
Carolinas (SE United States; 220 m, 920 m). On average, less than half the Rose Bengal-stained
foraminifera were actually living when collected. Thus, while Rose Bengal can significantly
overestimate abundance, combined analyses of CellTracker Green and Rose Bengal can provide
insights on population dynamics and effects of episodic events. Initial stable isotope analyses
indicate that the CellTracker Green method does not significantly affect these important
paleoceanographic proxies.Funding for this research was provided by the National Science Foundation Research

Comparison of breast and bowel cancer screening uptake patterns in a common cohort of South Asian women in England
Background: Inequalities in uptake of cancer screening by ethnic minority populations are well documented in a
number of international studies. However, most studies to date have explored screening uptake for a single cancer
only. This paper compares breast and bowel cancer screening uptake for a cohort of South Asian women invited to
undertake both, and similarly investigates these women's breast cancer screening behaviour over a period of fifteen
years.
Methods: Screening data for rounds 1, 2 and 5 (1989-2004) of the NHS breast cancer screening programme and for
round 1 of the NHS bowel screening pilot (2000-2002) were obtained for women aged 50-69 resident in the English
bowel screening pilot site, Coventry and Warwickshire, who had been invited to undertake breast and bowel cancer
screening in the period 2000-2002. Breast and bowel cancer screening uptake levels were calculated and compared
using the chi-squared test.
Results: 72,566 women were invited to breast and bowel cancer screening after exclusions. Of these, 3,539 were South
Asian and 69,027 non-Asian; 18,730 had been invited to mammography over the previous fifteen years (rounds 1 to 5).
South Asian women were significantly less likely to undertake both breast and bowel cancer screening; 29.9% (n =
1,057) compared to 59.4% (n = 40,969) for non-Asians (p < 0.001). Women in both groups who consistently chose to
undertake breast cancer screening in rounds 1, 2 and 5 were more likely to complete round 1 bowel cancer screening.
However, the likelihood of completion of bowel cancer screening was still significantly lower for South Asians; 49.5% vs.
82.3% for non-Asians, p < 0.001. South Asian women who undertook breast cancer screening in only one round were
no more likely to complete bowel cancer screening than those who decided against breast cancer screening in all
three rounds. In contrast, similar women in the non-Asian population had an increased likelihood of completing the
new bowel cancer screening test. The likelihood of continued uptake of mammography after undertaking screening in
round 1 differed between South Asian religio-linguistic groups. Noticeably, women in the Muslim population were less
likely to continue to participate in mammography than those in other South Asian groups.
Conclusions: Culturally appropriate targeted interventions are required to reduce observed disparities in cancer
screening uptakes
