Adverse mental health outcomes in breast cancer survivors compared to women who did not have cancer: systematic review protocol.
BACKGROUND: Recent increasing trends in breast cancer incidence and survival have resulted in unprecedented numbers of cancer survivors in the general population. A cancer diagnosis may have a profound psychological impact, and breast cancer treatments often cause long-term physical sequelae, potentially affecting women's mental health. The aim of this systematic review is to identify and summarise all studies that have compared mental health outcomes in breast cancer survivors, versus women who did not have cancer. METHODS: This study will be a systematic review of the literature. Four databases, including MEDLINE and PsycINFO, will be searched to identify potentially relevant studies. The search expressions will use a Boolean logic, including terms for the target population (women who have had breast cancer), outcomes (psychiatric disorders) and comparators (e.g. risk, hazard). All mental disorders will be eligible, except those with onset normally occurring during childhood or strong genetic basis (e.g. Huntington disease). The eligibility of the studies will be assessed in two phases: (1) considering the information provided in the title and abstract; (2) evaluating the full text. Studies including women diagnosed with breast cancer 1 year or more ago and that provide original data on mental health outcomes will be eligible. Studies in which all women were undergoing surgery, chemotherapy or radiotherapy, or hospitalised or institutionalised, will be excluded, as well as studies that include patients selected on the basis of symptomatology. Two investigators will do the screening of the references and the data extraction independently, with results compared and discrepancies resolved by involving a third investigator when necessary. Study quality and risk of bias will be assessed across six broad domains. Results will be summarised by outcome, and summary measures of frequency and/or association will be computed if possible. DISCUSSION: This review will summarise the evidence on the mental health outcomes of women who have been diagnosed with breast cancer. This information can be used to motivate further research and increase understanding of the most common mental health conditions affecting this growing population of women.

Associations Between Breast Cancer Survivorship and Adverse Mental Health Outcomes: A Systematic Review.
Background: We aimed to systematically review the evidence on adverse mental health outcomes in breast cancer survivors (≥1 year) compared with women with no history of cancer. Methods: Studies were identified by searching MEDLINE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, and the Social Sciences Citation Index, and through backward citation tracking. Two researchers selected the studies, extracted data, and assessed the risk of bias. Results: Sixty studies were included. Of 38 studies of depression, 33 observed more depression in breast cancer survivors; this was statistically significant in 19 studies overall, including six of seven where depression was ascertained clinically, three of four studies of antidepressants, and 13 of 31 that quantified depressive symptoms. Of 21 studies of anxiety, 17 observed more anxiety in breast cancer survivors, statistically significant in 11 studies overall, including two of four with clinical/prescription-based outcomes, and in eight of 17 of anxiety symptoms. Breast cancer survivors also had statistically significantly increased symptoms/frequency of neurocognitive dysfunction (18 of 24 studies), sexual dysfunctions (5 of 6 studies), sleep disturbance (5 of 5 studies), stress-related disorders/PTSD (2 of 3 studies), suicide (2 of 2 studies), somatisation (2 of 2 studies), and bipolar and obsessive-compulsive disorders (1 of 1 study each). Studies were heterogeneous in terms of participants' characteristics, time since diagnosis, ascertainment of outcomes, and measures reported. Approximately one-half of the studies were at high risk of selection bias and confounding by socio-economic status. Conclusions: There is compelling evidence of an increased risk of anxiety, depression and suicide, and neurocognitive and sexual dysfunctions in breast cancer survivors compared with women with no prior cancer. This information can be used to support evidence-based prevention and management strategies. Further population-based and longitudinal research would help to better characterize these associations

Exploring the provision of services to support people with cancer-related pain
Background. Cancer-related pain is the most reported symptom across all cancer types. Its impact on the person experiencing it is significant and reduces their quality of life. Cancer-related pain is complex, to ensure optimal management, it requires specialist support from the multi-disciplinary team. Aim: To map the current provision of these specialist services that focus on the management of cancer-related pain.Method: An online survey was developed by a team of specialists with expertise in cancer-related pain. The survey was circulated via social media platforms for a period of 4 weeks. Results: There were 63 survey responses from across England, with no responses from the other nations of the UK. 54.7% (n=35) services were multi-professional, the remaining services contain either one or two different professionals. 37% (n=23) did not accept referrals for those with late effects cancer pain and 20% (n=13) did not accept referrals for those undergoing palliative treatment. All respondents agreed more education and support is needed regarding cancer-related pain.Conclusion: The results of this survey indicate that the provision of cancer-related pain services across the UK is inconsistent. More work is needed to improve access to these services and healthcare professionals education of cancer-related pain
Preparing for low surface brightness science with the Vera C. Rubin Observatory: A Comparison of Observable and Simulated Intracluster Light Fractions
Intracluster Light (ICL) provides an important record of the interactions
galaxy clusters have undergone. However, we are limited in our understanding by
our measurement methods. To address this we measure the fraction of cluster
light that is held in the Brightest Cluster Galaxy and ICL (BCG+ICL fraction)
and the ICL alone (ICL fraction) using observational methods (Surface
Brightness Threshold-SB, Non-Parametric Measure-NP, Composite Models-CM,
Multi-Galaxy Fitting-MGF) and new approaches under development (Wavelet
Decomposition-WD) applied to mock images of 61 galaxy clusters (14<log10
M_200c/M_solar <14.5) from four cosmological hydrodynamical simulations. We
compare the BCG+ICL and ICL fractions from observational measures with those
using simulated measures (aperture and kinematic separations). The ICL
fractions measured by kinematic separation are significantly larger than
observed fractions. We find the measurements are related and provide equations
to estimate kinematic ICL fractions from observed fractions. The different
observational techniques give consistent BCG+ICL and ICL fractions but are
biased to underestimating the BCG+ICL and ICL fractions when compared with
aperture simulation measures. Comparing the different methods and algorithms we
find that the MGF algorithm is most consistent with the simulations, and CM and
SB methods show the smallest projection effects for the BCG+ICL and ICL
fractions respectively. The Ahad (CM), MGF and WD algorithms are best set up to
process larger samples, however, the WD algorithm in its current form is
susceptible to projection effects. We recommend that new algorithms using these
methods are explored to analyse the massive samples that Rubin Observatory's
Legacy Survey of Space and Time will provide.Comment: Submitted for publication in MNRAS, posted to arXiv after responding

High-spectral-resolution Observations of the Optical Filamentary Nebula Surrounding NGC 1275
We present new high-spectral-resolution observations (R = λ/Δλ = 7000) of the filamentary nebula surrounding NGC 1275, the central galaxy of the Perseus cluster. These observations have been obtained with SITELLE, an imaging Fourier transform spectrometer installed on the Canada–France–Hawai Telescope with a field of view of 11′×11′ , encapsulating the entire filamentary structure of ionized gas despite its large size of 80 kpc × 50 kpc. Here, we present renewed fluxes, velocities, and velocity dispersion maps that show in great detail the kinematics of the optical nebula at [S ii] λ6716, [S ii] λ6731, [N ii] λ6584, Hα (6563 Å), and [N ii] λ6548. These maps reveal the existence of a bright flattened disk-shaped structure in the core extending to r ∼10 kpc and dominated by a chaotic velocity field. This structure is located in the wake of X-ray cavities and characterized by a high mean velocity dispersion of 134 km s−1. The disk-shaped structure is surrounded by an extended array of filaments spread out to r ∼ 50 kpc that are 10 times fainter in flux, remarkably quiescent, and have a uniform mean velocity dispersion of 44 km s−1. This stability is puzzling given that the cluster core exhibits several energetic phenomena. Based on these results, we argue that there are two mechanisms that form multiphase gas in clusters of galaxies: a first triggered in the wake of X-ray cavities leading to more turbulent multiphase gas and a second, distinct mechanism, that is gentle and leads to large-scale multiphase gas spreading throughout the core
