We examined associations 97 dietary factors with risk 542,778 Million Women Study participants (12,251 incident cases over 16.6 years), and conducted a targeted genetic analysis ColoRectal Transdisciplinary Study, Colon Cancer Family Registry, Genetics Epidemiology Colorectal Consortium (GECCO).

BackgroundSocial isolation has been associated with increased risk of coronary heart disease and stroke. However, it is unclear whether the associations differ between fatal non-fatal events or by type (living alone having few social contacts). We aimed to examine these in two large UK prospective cohorts.MethodsMillion Women Study Biobank participants without previous stroke who provided data median year 2010 (IQR 2009–2011) on contacts were included this analysis. Participants followed up...

Ovarian cancer is the fifth leading cause of mortality in UK women. survival varies by disease stage at diagnosis, but evidence mixed on effect tumour histological type (histotype) and other factors. 1.3 million women completed a detailed health questionnaire 1996–2001 were followed for incident cancers deaths via linkage to national databases. Using Cox regression models, we estimated adjusted relative risks (RRs) death from ovarian cancer, histotype, 16 personal characteristics During 17.7...

Amiodarone is widely used in adults with congenital heart disease, but no systematic study has been published on its effects thyroid function these patients. A retrospective was performed to examine the frequency of amiodarone-associated dysfunction disease and identify any contributing factors.All (16 60 years old) were identified from a database if they had preexisting taken amiodarone for >/=6 months, currently followed up by 1 consultant (J.S.). Ninety-two patients found evaluated status...

Ovarian cancer risk is known to be reduced amongst women who have had children, but reported associations with breastfeeding are varied. Few studies sufficient power explore reliably these by tumour histotype. In a prospective study of 1.1 million UK women, 8719 developed ovarian during follow‐up. Cox regression yielded adjusted relative risks (RRs) overall and histotype different childbearing patterns. Nulliparous 24% greater than one child, significant heterogeneity ( p = 0.01).

With a range that covered most of northern Eurasia and parts North America, the cave lion (Panthera spelaea) was one widespread carnivores Late Pleistocene. Earlier ancient DNA analyses have shown it is distinct from modern lions, suggested demographic decline in Beringia during marine isotope stage 3 (MIS 3). Here, we further investigate Pleistocene population dynamics more detail by combining powerful algorithm couples MCMC with coalescent simulations under an approximate Bayesian...

Associations between behavioural and other personal factors colorectal cancer risk have been reported to vary by tumour characteristics, but evidence is inconsistent. In a large UK-based prospective study we examined associations of 14 postulated with overall, across three anatomical sites four morphological subtypes. Among 1.3 million women, 18,518 incident cancers were identified during 13.8 (SD 3.4) years follow-up via record linkage national registry data. Cox regression yielded adjusted...

Abstract Background Ethnic minority women are commonly reported to have more aggressive breast cancer than White women, but there is little contemporary national evidence available. Methods We analysed data from the National Cancer Registration and Analysis Service on diagnosed with invasive during 2013–2018. Multivariable logistic regression yielded adjusted odds ratios (and 95% confidence intervals) of less favourable tumour characteristics (high stage, high grade, ER negative, Her2...

We investigated associations for 26 site-specific large UK cohort. Study participants completed questionnaire on reproductive lifestyle factors 1996–2001, were followed death via national registries. Using Cox regression models, we estimated adjusted relative risks (RRs) among women vs without tubal ligation. In 1 278 783 previous...
