on coastal fishing communities is the lack of understanding of the interactions between
changes in fish stocks and waterfront land uses. This study examines these interactions
in the New Bedford/Fairhaven area using parcel level data and geographic information
system (GIS) tools. Logistic regression models were used to assess the impact of
changes in marine resource abundance on waterfront land uses. Although land-use
decisions are influenced by many complex market and regulatory factors, our study
detected a significant relationship between fish stock conditions and coastal land uses.This research was supported by the National Atmospheric and

Missing children: risks, repeats and responses
Investigating reports of missing children is a major source of demand for the police in the UK. Repeat disappearances are common, can indicate underlying vulnerabilities and have been linked with various forms of exploitation and abuse. Inspired by research on repeat victimisation, this paper examines the prevalence and temporal patterns of repeat missing episodes by children, as well as the characteristics of those involved. Using data on all missing children incidents recorded by one UK police service in 2015 (n = 3,352), we find that: (a) 75% of missing incidents involving children were repeats, i.e. attributed to children who had already been reported missing in 2015; (b) a small proportion of repeatedly missing children (n = 59; 4%) accounted for almost a third of all missing children incidents (n = 952, 28%); (c) over half of all first repeat disappearances occurred within four weeks of an initial police recorded missing episode; and (d) children recorded as missing ten times or more over the one year study period were significantly more likely than those recorded missing once to be teenagers, in the care system or to have drug and/or alcohol dependencies. We conclude by discussing the implications of our findings for future research and the prevention of repeat disappearances by children
Male breast cancer in BRCA1 and BRCA2 mutation carriers: pathology data from the Consortium of Investigators of Modifiers of BRCA1/2
Background
BRCA1 and, more commonly, BRCA2 mutations are associated with increased risk of male breast cancer (MBC). However, only a paucity of data exists on the pathology of breast cancers (BCs) in men with BRCA1/2 mutations. Using the largest available dataset, we determined whether MBCs arising in BRCA1/2 mutation carriers display specific pathologic features and whether these features differ from those of BRCA1/2 female BCs (FBCs).
Methods
We characterised the pathologic features of 419 BRCA1/2 MBCs and, using logistic regression analysis, contrasted those with data from 9675 BRCA1/2 FBCs and with population-based data from 6351 MBCs in the Surveillance, Epidemiology, and End Results (SEER) database.
Results
Among BRCA2 MBCs, grade significantly decreased with increasing age at diagnosis (P = 0.005). Compared with BRCA2 FBCs, BRCA2 MBCs were of significantly higher stage (P for trend = 2 × 10−5) and higher grade (P for trend = 0.005) and were more likely to be oestrogen receptor–positive [odds ratio (OR) 10.59; 95 % confidence interval (CI) 5.15–21.80] and progesterone receptor–positive (OR 5.04; 95 % CI 3.17–8.04). With the exception of grade, similar patterns of associations emerged when we compared BRCA1 MBCs and FBCs. BRCA2 MBCs also presented with higher grade than MBCs from the SEER database (P for trend = 4 × 10−12).
Conclusions
On the basis of the largest series analysed to date, our results show that BRCA1/2 MBCs display distinct pathologic characteristics compared with BRCA1/2 FBCs, and we identified a specific BRCA2-associated MBC phenotype characterised by a variable suggesting greater biological aggressiveness (i.e., high histologic grade). These findings could lead to the development of gender-specific risk prediction models and guide clinical strategies appropriate for MBC management
Assessment of polygenic architecture and risk prediction based on common variants across fourteen cancers
Abstract: Genome-wide association studies (GWAS) have led to the identification of hundreds of susceptibility loci across cancers, but the impact of further studies remains uncertain. Here we analyse summary-level data from GWAS of European ancestry across fourteen cancer sites to estimate the number of common susceptibility variants (polygenicity) and underlying effect-size distribution. All cancers show a high degree of polygenicity, involving at a minimum of thousands of loci. We project that sample sizes required to explain 80% of GWAS heritability vary from 60,000 cases for testicular to over 1,000,000 cases for lung cancer. The maximum relative risk achievable for subjects at the 99th risk percentile of underlying polygenic risk scores (PRS), compared to average risk, ranges from 12 for testicular to 2.5 for ovarian cancer. We show that PRS have potential for risk stratification for cancers of breast, colon and prostate, but less so for others because of modest heritability and lower incidence
{Search for direct production of GeV-scale resonances decaying to a pair of muons in proton-proton collisions at = 13 TeV}
A search for direct production of low-mass dimuon resonances is performed using = 13 TeV proton-proton collision data collected by the CMS experiment during the 2017–2018 operation of the CERN LHC with an integrated luminosity of 96.6 fb−1. The search exploits a dedicated high-rate trigger stream that records events with two muons with transverse momenta as low as 3 GeV but does not include the full event information. The search is performed by looking for narrow peaks in the dimuon mass spectrum in the ranges of 1.1–2.6 GeV and 4.2–7.9 GeV. No significant excess of events above the expectation from the standard model background is observed. Model-independent limits on production rates of dimuon resonances within the experimental fiducial acceptance are set. Competitive or world’s best limits are set at 90% confidence level for a minimal dark photon model and for a scenario with two Higgs doublets and an extra complex scalar singlet (2HDM+S). Values of the squared kinetic mixing coefficient ε2 in the dark photon model above 10−6 are excluded over most of the mass range of the search. In the 2HDM+S, values of the mixing angle sin(θH) above 0.08 are excluded over most of the mass range of the search with a fixed ratio of the Higgs doublets vacuum expectation tan β = 0.5
Assessing short- and long-term outcomes among black vs white Medicare patients undergoing resection of colorectal cancer
BACKGROUND: We sought to identify differences among black and white Medicare-insured patients with colorectal cancer who underwent resection. METHODS: Surveillance, Epidemiology and End Results–Medicare (SEER-Medicare) linked inpatient data from 1986 to 2005 were examined. Differences in short- and long-term outcomes among black vs white patients were investigated. RESULTS: There were 125,676 (92.4%) white and 9,891 (7.6%) black patients who met the criteria. Black patients were younger (75.5 vs 77.2 years; P < .001) but had more comorbidities than did white patients (mean Charlson comorbidity index score 3.99 vs 3.87; P < .001). Black patients demonstrated greater odds of in-hospital mortality (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.30 to 1.56) and readmission within 30 days (OR, 1.26; 95% CI, 1.18 to 1.34). Comparing 1986 to 1990 vs 2001 to 2005, black patients had greater odds of 30-day readmission (OR, 1.12 vs 1.31) but reduced odds of index in-hospital mortality (OR, 1.84 vs 1.28). Black patients had worse long-term survival after colorectal surgery (hazard ratio [HR], 1.21; 95% CI, 1.17 to 1.25; P < .001). CONCLUSIONS: Black patients with colorectal cancer demonstrated increased risk of mortality and readmission after controlling for age, sex, and comorbidities. Although black vs white differences in perioperative mortality decreased over time, disparities in readmission and long-term survival persisted
