A clinical guide to the management of genitourinary symptoms in breast cancer survivors on endocrine therapy.
There is increasing attention and concern about managing the adverse effects of adjuvant endocrine therapy for women with early breast cancer as the side effects of therapy influence compliance and can impair quality of life (QoL). Most side effects associated with tamoxifen (TAM) and aromatase inhibitors (AIs) are directly related to estrogen deprivation, and the symptoms are similar to those experienced during natural menopause but appear to be more severe than that seen in the general population. Prolonged estrogen deprivation may lead to atrophy of the vulva, vagina, lower urinary tract and supporting pelvic structures, resulting in a range of genitourinary symptoms that can in turn lead to pain, discomfort, impairment of sexual function and negatively impact on multiple domains of QoL. The genitourinary side effects may be prevented, reduced and managed in most cases but this requires early recognition and appropriate treatment. We provide an overview of practical clinical approaches to understanding the pathophysiology and the management of genitourinary symptoms in postmenopausal women receiving adjuvant endocrine therapy for breast cancer
Making hard choices easier: a prospective, multicentre study to assess the efficacy of a fertility-related decision aid in young women with early-stage breast cancer
BACKGROUND: Fertility is a priority for many young women with breast cancer. Women need to be informed about interventions to retain fertility before chemotherapy so as to make good quality decisions. This study aimed to prospectively evaluate the efficacy of a fertility-related decision aid (DA). METHODS: A total of 120 newly diagnosed early-stage breast cancer patients from 19 Australian oncology clinics, aged 18–40 years and desired future fertility, were assessed on decisional conflict, knowledge, decision regret, and satisfaction about fertility-related treatment decisions. These were measured at baseline, 1 and 12 months, and were examined using linear mixed effects models. RESULTS: Compared with usual care, women who received the DA had reduced decisional conflict (β=−1.51; 95%CI: −2.54 to 0.48; P=0.004) and improved knowledge (β=0.09; 95%CI: 0.01–0.16; P=0.02), after adjusting for education, desire for children and baseline uncertainty. The DA was associated with reduced decisional regret at 1 year (β=−3.73; 95%CI: −7.12 to −0.35; P=0.031), after adjusting for education. Women who received the DA were more satisfied with the information received on the impact of cancer treatment on fertility (P<0.001), fertility options (P=0.005), and rated it more helpful (P=0.002), than those who received standard care. CONCLUSION: These findings support widespread use of this DA shortly after diagnosis (before chemotherapy) among younger breast cancer patients who have not completed their families

The definitive version was published in Journal of Petrology 51 (2010): 1447-1475, doi:10.1093/petrology/egq025.We present compositional data on a suite of 18 primitive neovolcanic alkali basalts from three
flank zone regions in Iceland (Vestmannaeyjar in the south, Snæfell in the east, and Snæfellsnes
in the west) that are peripheral to the main rift zones that are dominated by tholeiitic basalts. This
study integrates He isotope data with radiogenic isotope data (Sr-Nd-Pb-Hf), stable isotope data
(δ18O), and trace element data to characterise the compositional features of the trace-elementenriched
components of the Icelandic mantle. We also present high-precision Pb isotope data on
an additional 57 lava samples from the flank zones (including Öræfajökull in the south-east) and
the Northern and Eastern rift zones. Most Icelandic lavas have negative Δ207Pb (–4 to –1), with
higher values (–1 to +4) found only in samples from Öræfajökull, Snæfell, and parts of the
Reykjanes Peninsula. At Snæfell, this EM1-type component is characterised by a low δ18Oolivine
signature (+4.1‰ to +4.6‰), moderate 206Pb/204Pb values (18.4-18.6) and MORB-like 3He/4He
(6.9-7.5 R/RA). Samples from Vestmannaeyjar and Snæfellsnes have mantle-like δ18Oolivine
(+4.9‰ to +5.0‰), and radiogenic 206Pb/204Pb values (18.9-19.3) that fall on the NHRL for
208Pb/204Pb (Δ208Pb –5 to +5). Compared to the Vestmannaeyjar lavas, Snæfellsnes lavas have
higher La/YbN (5-11 vs. 3-5), lower εNd (5.5-6.5 vs. 6.8-7.6) and lower 3He/4He (6.3-8.6 R/RA vs.
11.4-13.5 R/RA). Therefore, the most trace element enriched components in the Icelandic mantle
are not the carriers of the high 3He/4He values (> 15 R/RA) found in some lavas on Iceland and
the adjacent ridges, and instead are consistent with degassed, recycled components. Even after
excluding the EM1-type high Δ207Pb samples, high-precision Pb isotope data produce a kinked
array on an 206Pb/204Pb vs. 208Pb/204Pb plot, which is not consistent with simple binary mixing
between two end-members. This requires significant lateral heterogeneity within the Icelandic
mantle and the presence of more than just two compositionally-distinct local mixing end-member
components. Samples from each of the main axial rift zones define different trends. Despite the
tectonic continuity between the Northern Volcanic Zone and the Eastern Volcanic Zone, lavas
from these two rift zones define separate sub-parallel linear arrays. Lavas from the adjacent
Western Volcanic Zone and the Eastern Volcanic Zone define oblique linear arrays that converge
on a common local end-member that is not involved in the magmatism of the Northern Volcanic
Zone. Therefore, there is a distinct NE-SW compositional heterogeneity within the Icelandic
mantle.work was funded primarily by the Danish National Research

Establishing a proactive safety and health risk management system in the fire service
BACKGROUND: Formalized risk management (RM) is an internationally accepted process for reducing hazards in the workplace, with defined steps including hazard scoping, risk assessment, and implementation of controls, all within an iterative process. While required for all industry in the European Union and widely used elsewhere, the United States maintains a compliance-based regulatory structure, rather than one based on systematic, risk-based methodologies. Firefighting is a hazardous profession, with high injury, illness, and fatality rates compared with other occupations, and implementation of RM programs has the potential to greatly improve firefighter safety and health; however, no descriptions of RM implementation are in the peer-reviewed literature for the North American fire service. METHODS: In this paper we describe the steps used to design and implement the RM process in a moderately-sized fire department, with particular focus on prioritizing and managing injury hazards during patient transport, fireground, and physical exercise procedures. Hazard scoping and formalized risk assessments are described, in addition to the identification of participatory-led injury control strategies. Process evaluation methods were conducted to primarily assess the feasibility of voluntarily instituting the RM approach within the fire service setting. RESULTS: The RM process was well accepted by the fire department and led to development of 45 hazard specific-interventions. Qualitative data documenting the implementation of the RM process revealed that participants emphasized the: value of the RM process, especially the participatory bottom-up approach; usefulness of the RM process for breaking down tasks to identify potential risks; and potential of RM for reducing firefighter injury. CONCLUSIONS: As implemented, this risk-based approach used to identify and manage occupational hazards and risks was successful and is deemed feasible for U.S. (and other) fire services. While several barriers and challenges do exist in the implementation of any intervention such as this, recommendations for adopting the process are provided. Additional work will be performed to determine the effectiveness of select controls strategies that were implemented; however participants throughout the organizational structure perceived the RM process to be of high utility while researchers also found the process improved the awareness and engagement in actively enhancing worker safety and health.This item is part of the UA Faculty Publications collection.

Improving women's knowledge about prenatal screening in the era of non-invasive prenatal testing for Down syndrome - development and acceptability of a low literacy decision aid.
BACKGROUND: Access to information about prenatal screening is important particularly in light of new techniques such as non-invasive prenatal testing (NIPT). This study aimed to develop and examine the acceptability of a low literacy decision aid (DA) about Down syndrome screening among pregnant women with varying education levels and GPs. METHODS: We developed a DA booklet providing information about first-trimester combined testing, maternal serum screening, and NIPT. GPs and women participated in a telephone interview to examine the acceptability of the DA and measure screening knowledge before and after reading the DA. The knowledge measure was designed to assess whether women had understood the gist of the information presented in the decision aid. It comprised conceptual questions (e.g. screening tells you the chance of having a baby with Down syndrome) and numeric questions (e.g. the accuracy of different screening tests). RESULTS: Twenty-nine women and 18 GPs participated. Regardless of education level, most women found the booklet 'very' clearly presented (n = 22, 76%), and 'very' informative (n = 23, 80%). Overall, women's conceptual and numeric knowledge improved after exposure to the DA, from 4% having adequate knowledge to 69%. Women's knowledge of NIPT also improved after receiving the decision aid, irrespective of education. Most GPs found it 'very' clearly presented (n = 13, 72%), and that it would 'very much' facilitate decision-making (n = 16, 89%). CONCLUSIONS: The DA was found to be acceptable to women as well as GPs. A comprehensive evaluation of the efficacy of the decision aid compared to standard information is an important next step. Strategies are needed on how to implement the tool in practice
Isotopic evidence for mobility in the Copper and Bronze Age Cemetery of Humanejos (Parla, Madrid): a diachronic approach using biological and archaeological variables
Over the last several decades, the application of aDNA and strontium isotope analyses
on archaeologically recovered human remains has provided new avenues for the
investigation of mobility in past societies. Data on human mobility can be valuable
in the reconstruction of prehistoric residential patterns and kinship systems, which
are at the center of human social organization and vary across time and space. In
this paper, we aim to contribute to our understanding of mobility, residence, and
kinship patterns in late Prehistoric Iberia (c. 3300–1400BC) by providing new strontium
data on 44 individuals from the site of Humanejos (Parla, Madrid). The study
presented here is multi-proxy and looks at these new data by interweaving biological,
chronological, and archaeological information. This analysis found that 7/44
individuals buried at Humanejos could be identified as non-local to the necropolis.
Although more men (n = 5) than women (n = 2) were found in the non-local category,
and more non-local individuals were identified in the pre-Bell Beaker (n = 5)
than in Bell Beaker (n = 1) or Bronze Age (n = 1), we find no statistically significant
differences concerning sex or time period. This contrasts with other archaeological
datasets for late prehistoric Europe which suggest higher female mobility, female
exogamy, and male-centered residential patterns were common. At Humanejos, we
have also identified one non-local female whose exceptional Beaker grave goods
suggest she was an individual of special status, leading to additional questions about
the relationships between gender, mobility, and social position in this region and

Exploring the facilitators and barriers to using an online infertility risk prediction tool (FoRECAsT) for young women with breast cancer: A qualitative study protocol
INTRODUCTION: As cancer treatments may impact on fertility, a high priority for young patients with breast cancer is access to evidence-based, personalised information for them and their healthcare providers to guide treatment and fertility-related decisions prior to cancer treatment. Current tools to predict fertility outcomes after breast cancer treatments are imprecise and do not offer individualised prediction. To address the gap, we are developing a novel personalised infertility risk prediction tool (FoRECAsT) for premenopausal patients with breast cancer that considers current reproductive status, planned chemotherapy and adjuvant endocrine therapy to determine likely post-treatment infertility. The aim of this study is to explore the feasibility of implementing this FoRECAsT tool into clinical practice by exploring the barriers and facilitators of its use among patients and healthcare providers. METHODS AND ANALYSIS: A cross-sectional exploratory study is being conducted using semistructured in-depth telephone interviews with 15-20 participants each from the following groups: (1) premenopausal patients with breast cancer younger than 40, diagnosed within last 5 years, (2) breast surgeons, (3) breast medical oncologists, (4) breast care nurses (5) fertility specialists and (6) fertility preservation nurses. Patients with breast cancer are being recruited from the joint Breast Service of three affiliated institutions of Victorian Comprehensive Cancer Centre in Melbourne, Australia-Peter MacCallum Cancer Centre, Royal Melbourne Hospital and Royal Women's Hospital, and clinicians are being recruited from across Australia. Interviews are being audio recorded, transcribed verbatim and imported into qualitative data analysis software to facilitate data management and analyses. ETHICS AND DISSEMINATION: The study protocol has been approved by Melbourne Health Human Research Ethics Committee, Australia (HREC number: 2017.163). Confidentiality and privacy are maintained at every stage of the study. Findings will be disseminated through peer-reviewed scholarly and scientific journals, national and international conference presentations, social media, broadcast media, print media, internet and various community/stakeholder engagement activities
Sr-Nd-Pb-Hf isotope results from ODP Leg 187: Evidence for mantle dynamics of the Australian-Antarctic Discordance and origin of the Indian MORB source
New high precision PIMMS Hf and Pb isotope data for 14–28 Ma basalts recovered during ODP Leg 187 are compared with zero-age dredge samples from the Australian-Antarctic Discordance (AAD). These new data show that combined Nd-Hf isotope systematics can be used as an effective discriminant between Indian and Pacific MORB source mantle domains. In particular, Indian mantle is displaced to lower εNd and higher εHf ratios compared to Pacific mantle. As with Pb isotope plots, there is almost no overlap between the two mantle types in Nd-Hf isotope space. On the basis of our new Nd-Hf isotope data, we demonstrate that Pacific MORB-source mantle was present near the eastern margin of the AAD from as early as 28 Ma, its boundary with Indian MORB-source mantle coinciding with the eastern edge of a basin-wide arcuate depth anomaly that is centered on the AAD. This observation rules out models requiring rapid migration of Pacific MORB mantle into the Indian Ocean basin since separation of Australia from Antarctica. Although temporal variations in isotopic composition can be discerned relative to the fracture zone boundary of the modern AAD at 127°E, the distribution of different compositional groups appears to have remained much the same relative to the position of the residual depth anomaly for the past 30 m.y. Thus significant lateral flow of mantle along the ridge axis toward the interface appears unlikely. Instead, the dynamics that maintain both the residual depth anomaly and the isotopic boundary between Indian and Pacific mantle are due to eastward migration of the Australian and Antarctic plates over a stagnated, but slowly upwelling, slab oriented roughly orthogonal to the ridge axis. Temporal and spatial variations in the compositions of Indian MORB basalts within the AAD can be explained by progressive displacement of shallower Indian MORB-source mantle by deeper mantle having a higher εHf composition ascending ahead of the upwelling slab. Models for the origin of the distinctive composition of the Indian MORB-source based on recycling of a heterogeneous enriched component that consist of ancient altered ocean crust plus<10% pelagic sediment are inconsistent with Nd-Hf isotope systematics. Instead, the data can be explained by a model in which Indian mantle includes a significant proportion of material that was processed in the mantle wedge above a subduction zone and was subsequently mixed back into unprocessed upper mantle
Are publicly available internet resources enabling women to make informed fertility preservation decisions before starting cancer treatment: an environmental scan?
Background To identify publicly available internet resources and assess their likelihood to support women making informed decisions about, and between, fertility preservation procedures before starting their cancer treatment. Methods A survey of publically available internet resources utilising an environmental scan method. Inclusion criteria were applied to hits from searches of three data sources (November 2015; repeated June 2017): Google (Chrome) for patient resources; repositories for clinical guidelines and projects; distribution email lists to contact patient decision aid experts. The Data Extraction Sheet applied to eligible resources elicited: resource characteristics; informed and shared decision making components; engagement health services. Results Four thousand eight hundred fifty one records were identified; 24 patient resources and 0 clinical guidelines met scan inclusion criteria. Most resources aimed to inform women with cancer about fertility preservation procedures and infertility treatment options, but not decision making between options. There was a lack of consistency about how health conditions, decision problems and treatment options were described, and resources were difficult to understand. Conclusions Unless developed as part of a patient decision aid project, resources did not include components to support proactively women’s fertility preservation decisions. Current guidelines help people deliver information relevant to treatment options within a single disease pathway; we identified five additional components for patient decision aid checklists to support more effectively people’s treatment decision making across health pathways, linking current with future health problems
