Abstract
Objectives To investigate ethnic differences in falls and road traffic injuries (RTIs) in Scotland. Study design A retrospective cohort of 4.62 million people, linking the Scottish Census 2001, with self-reported ethnicity, to hospitalisation and death records for 2001–2013. Methods We selected cases with International Classification of Diseases–10 diagnostic codes for falls and RTIs. Using Poisson regression, age-adjusted risk ratios (RRs, multiplied by 100 as percentages) and 95% confidence intervals (CIs) were calculated by sex for 10 ethnic groups with the White Scottish as reference. We further adjusted for country of birth and socio-economic status (SES). Results During about 49 million person-years, there were 275,995 hospitalisations or deaths from fall-related injuries and 43,875 from RTIs. Compared with the White Scottish, RRs for falls were higher in most White and Mixed groups, e.g., White Irish males (RR: 131; 95% CI: 122–140) and Mixed females (126; 112–143), but lower in Pakistani males (72; 64–81) and females (72; 63–82) and African females (79; 63–99). For RTIs, RRs were higher in other White British males (161; 147–176) and females (156; 138–176) and other White males (119; 104–137) and females (143; 121–169) and lower in Pakistani females (74; 57–98). The ethnic variations differed by road user type, with few cases among non-White motorcyclists and non-White female cyclists. The RRs were minimally altered by adjustment for country of birth or SES. Conclusion We found important ethnic variations in injuries owing to falls and RTIs, with generally lower risks in non-White groups. Culturally related differences in behaviour offer the most plausible explanation, including variations in alcohol use. The findings do not point to the need for new interventions in Scotland at present. However, as the ethnic mix of each country is unique, other countries could benefit from similar data linkage-based research. Ethnic inequalities in injuries are demonstrated in Scotland based on a large sample size and a fine ethnic granularity. White minority ethnic groups had the highest risks of fall-related injuries in Scotland. Fall-related injuries were the least likely in the Pakistani population. Ethnic differences in road traffic injuries varied by the type of road user. Ethnic differences in injuries were not explained by socio-economic status or country of birth.

Abstract
This article reports on a study of the psychosocial adjustment to age-related macular degeneration of 30 elderly persons by comparing the responses of subjects with this condition to those from age- and sex-matched controls on four psychosocial scales: life satisfaction, daily hassles, social support, and self-esteem. The subjects with the condition reported significantly poorer life satisfaction and greater stress, perhaps as a result of poor social support.

Abstract
Abstract
Achloroform-methanol extraction method (complete extraction of fat in 3 min) for determining fat in processed and prepared foods has been studied collaboratively. Fourteen collaborators reported single replicate fat results on 7 samples representative of various food types and 2 spiked samples by the proposed method. Each sample was accompanied by a blind duplicate. For statistical purposes, the blind duplicates were treated as paired observations, and there were 2 laboratory outliers. There was a 97.9% agreement among the results from the remaining 12 collaborators and the Associate Referee for the unfortified samples. Recoveries of 93.8 and 98.3% were obtained on fortified samples, based on results obtained from 11 collaborators. The statistical analysis of the results indicate (ranges for standard deviations were Sr = 0.083-0.528, Sb = 0.101-0.379, Sd = 8.130-0.631, for fat values ranging from 1.58 to 26.91%) that this method is adequate for quantitating the fat content in a wide variety of processed foods for nutritional labeling. The method has been adopted official first action.

Abstract
Abstract
Introduction
Metastasis is the primary cause of cancer-related death, with genomic evolution between primary and metastatic breast cancer only recently being studied in smaller numbers. We reconstructed the tumor evolution of a female patient originally diagnosed with localized ER+ HER2- disease to investigate the molecular changes that triggered relapse after long term aromatase inhibitor (AI) therapy and tracked them during subsequent treatments. The patient was diagnosed in 2002, relapsed in 2012 (regional lymph node), progressed in 2015 (liver metastasis), and passed away in 2018. We performed DNA- and RNA-sequencing on FFPE tumor samples and multiple liquid biopsies. The patient underwent eight lines of therapy including genome guided targeted therapy.
Materials and Methods
Whole exome and transcriptome sequencing was performed on the patient's primary tumor site at diagnosis (T1) and a metastatic lymph node (M1). Targeted DNA sequencing was performed on a metastatic liver sample (M2, 315 genes) and on liquid biopsies (n=11, 70 genes) every 2-3 months from 2015-2018.
Results
The mutational landscape between timepoints T1, M1 and M2 revealed low mutational burden at diagnosis which ultimately doubled at progression with active mutational processes (APOBEC, POLE) showing concordance between timepoints. DNA-based analysis revealed multiple mutations in the PI3K-Akt signaling pathway. Two mutations were shared between the samples: a clonal PIK3CA Q546R and a TP53 E180K mutation detected as clonal in M1/M2 and subclonal in T1. Individual samples carried private driver mutations, ranging from n=4 in T1, n=7 in M1 to n=16 in M2. While T1 harbored a single clonal driver mutation, with additional driver mutations being subclonal, M1 and M2 harbored multiple clonal driver mutations and a smaller percentage of subclonal driver mutations. A phylogenetic tree showed branching off between T1 and M1/M2. Liquid biopsies, while initially negative, started to detect mutations found among T1, M1 and M2, with increasing allele frequency (AF) throughout time. By the end of 2016, an ESR1 E380Q mutation not previously detected was found at a low AF that had rapidly increased by the end of 2017. RNA-Seq analysis revealed 908 (209 up, 699 down) genes to be differentially expressed between T1 and M1. Most significantly downregulated genes in M1 were TFF1 and PGR indicating loss-of-sensitivity / resistance to AI therapy. Most upregulated genes in M1 included PTHLH, S100P, and SOX2 which have been implicated in promoting tumor growth and metastasis. Pathway analysis between T1 and M1 showed enrichment for the hallmark gene sets ‘Estrogen Response early and late’ and ‘Epithelial mesenchymal transition’.
Conclusions
This phylogenetic reconstruction of the life history of a single patient's cancer revealed an increased mutational rate over time between the patient's primary tumor at diagnosis and samples taken at relapse; and a high level of heterogeneity with metastatic sites sharing only one driver mutation with the primary tumor at diagnosis and having acquired multiple de-novo driver mutations. Transcriptome profiling aided in uncovering the mechanisms that lead to the patient's initial relapse, indicating expression profile changes that promote tumor progression and metastasis as well as reduced sensitivity / resistance to the patients AI based therapy. Monitoring tumor progression through frequent liquid biopsies allowed for the detection of mutations from multiple metastatic sites, in addition to the detection and growth of an AI resistant clone harboring an ESR1 E380Q mutation that was not present in any of the solid tissue samples.

Abstract
BACKGROUND The current AAP clinical practice guidelines for the management of pediatric obesity recommend a structured, comprehensive, multi-disciplinary clinical intervention. However, there is a gap in the current literature on standardized curriculums for implementation of such programs. The objective of the present study is to adapt an evidenced-based, family- centered, weekly, weight management curriculum that addresses nutritional, physical activity and behavioral topics for a clinical care model at a tertiary care children's hospital. METHODS The curriculum was adapted for use in six individual sessions offered monthly by a multidisciplinary team, including a health educator, physician, dietitian, physical therapist and psychologist. Each provider offered specific feedback and curriculum adaptation based on their specialty. All team members completed training with scheduled treatment fidelity monitoring during implementation. To evaluate the effectiveness of the adapted curriculum, 60 adolescents, ages 14-18 years, with overweight or obesity, and at least one family member, will complete the six month intervention. The primary outcome is mean change in zBMI and %BMIp95 at six month and 18 months. Secondary outcomes include retention, satisfaction, effect on metabolic factors and activity level. CONCLUSION There is a paucity of literature on utilizing a standard curriculum in clinical weight management programs. Drawing from evidenced-based curriculum to strengthen clinical care creates an opportunity to improve existing clinical programs and potentially increase access and implementation of the current treatment recommendations for this high risk population.

Abstract
Abstract
Ten laboratories participated in a collaborative study to determine the total moisture and fat in raw and processed meat products by microwave drying and nuclear magnetic resonance (NMR) spectroscopy. Meat products were prepared following the AOAC Method and analyzed using CEM Corp.'s SMART Trac Moisture and Fat Analysis system. SMART Trac provides moisture results by measuring the weight loss on drying by microwave energy. The dried sample is then analyzed by NMR spectrometry for fat content. Moisture and fat results are displayed and reported by the SMART Trac as a percentage (g/100 g). Microwave drying is an AOAC-approved reference method (Method 985.14), Moisture in Meat and Poultry Products. NMR spectrometry is a secondary technique used to determine the concentration of various constituents in biological, organic, or chemical samples. The study design was based on Youden's matched pair principle for collaborative tests. For the purposes of this study, 10 laboratories each tested 10 Youden matched pairs, for a total of 20 samples. The study samples represented a range of products processed daily in plant operations. Included were raw meat samples (beef, pork, chicken, and turkey) as well as processed meats (beef hot dog, pork sausage, and ham). The total moisture content of the undiluted samples, as received for the purposes of this study, was determined by AOAC Method 950.46 and ranged from 54.03 to 74.99. The total fat content of the undiluted samples was determined by AOAC Method 960.39 and ranged from 1.00 to 29.79. Statistical analysis of study results for total moisture yielded a relative standard deviation for repeatability (RSDr) range of 0.14 to 0.95 and a relative standard deviation for reproducibility (RSDR) range of 0.26 to 0.95. Statistical analysis for total fat yielded similar RSDr and RSDR range of 0.74 to 4.08. Results for turkey had higher RSDr and RSDR values, both at 12.6, due to low fat content and possibly to the separation of the samples observed by some of the collaborators. Results demonstrate that microwave drying with NMR is a rapid, practical method providing results equivalent to AOAC Methods 950.46 (Forced Air Oven Drying) and 960.39 (Soxhlet Ether Extraction) in raw and processed meat products.

Abstract
BACKGROUND The gut microbiota composition is known to be influenced by a myriad of factors including the host genetic profile and a number of environmental influences. Here, we focus on the environmental influence of cohabitation on the gut microbiota as well as whether these environmentally influenced microorganisms are associated with cardiometabolic and inflammatory burden. We perform this by investigating the gut microbiota composition of various groups of related individuals including cohabitating monozygotic (MZ) twin pairs, non-cohabitating MZ twin pairs and spouse pairs. RESULTS A stronger correlation between alpha diversity was found in cohabitating MZ twins (45 pairs, r = 0.64, p = 2.21 × 10- 06) than in non-cohabitating MZ twin pairs (121 pairs, r = 0.42, p = 1.35 × 10- 06). Although the correlation of alpha diversity did not attain significance between spouse pairs (42 pairs, r = 0.23, p = 0.15), the correlation was still higher than those in the 209 unrelated pairs (r = - 0.015, p = 0.832). Bray-Curtis (BC) dissimilarity metrics showed cohabitating MZ twin pairs had the most similar gut microbiota communities which were more similar than the BC values of non-cohabitating MZ twins (empirical p-value = 0.0103), cohabitating spouses (empirical p-value = 0.0194), and pairs of unrelated non-cohabitating individuals (empirical p-value< 0.00001). There was also a significant difference between the BC measures from the spouse pairs and those from the unrelated non-cohabitating individuals (empirical p-value< 0.00001). Intraclass correlation coefficients were calculated between the various groups of interest and the results indicate the presence of OTUs with an environmental influence and one OTU that appeared to demonstrate genetic influences. One of the OTUs (Otu0190) was observed to have a significant association with both the cardiometabolic and inflammatory burden scores (p's < 0.05). CONCLUSIONS Through the comparison of the microbiota contents of MZ twins with varying cohabitation status and spousal pairs, we showed evidence of environmentally influenced OTUs, one of which had a significant association with cardiometabolic and inflammatory burden scores.

Abstract
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy clustering. Here we present combined results from these probes, deriving constraints on the equation of state, w, of dark energy and its energy density in the Universe. Independently of other experiments, such as those that measure the cosmic microwave background, the probes from this single photometric survey rule out a Universe with no dark energy, finding w=-0.80_{-0.11}^{+0.09}. The geometry is shown to be consistent with a spatially flat Universe, and we obtain a constraint on the baryon density of Ω_{b}=0.069_{-0.012}^{+0.009} that is independent of early Universe measurements. These results demonstrate the potential power of large multiprobe photometric surveys and pave the way for order of magnitude advances in our constraints on properties of dark energy and cosmology over the next decade.

Abstract
BACKGROUND The purpose of this study was to test the sensitivity and specificity of eight undergraduate volunteer examiners conducting vision screening tests in a community setting, in order to determine if non-eye care professionals were able to be trained to an appropriate level of skill. METHODS Eight undergraduate volunteer examiners were trained to conduct vision screening tests to address a gap in pediatric community eye care. Phase I of the study was implemented in the pediatric ophthalmology clinic, and phase II was conducted in nine local schools. Phase I consisted of 40 h of training for each volunteer regarding specific vision tests. Phase II consisted of screening children at nine local schools. RESULTS A total of 690 children from nine local schools were screened by both the volunteer examiners and the optometrist during the course of this study. Volunteer examiners had a screening sensitivity of 0.80 (95%CI 0.66-0.90) and screening specificity of 0.75 (95%CI 0.71-0.78) when compared to the study optometrist. The overall accuracy of volunteer examiners was 75%. The resulting positive likelihood ratio was 3.24 (95%CI 2.6-3.9), indicating that a child with vision impairment was 3.2 times more likely to fail the vision test performed by the volunteer examiners compared to a child with no vision impairment. CONCLUSIONS Non-healthcare professionals can be trained to an acceptable degree of accuracy to perform vision screening tests on children, which may assist in mitigating existing gaps in paediatric eye care.

Abstract
Abstract
Background:
The treatment landscape for women with HR+/HER2- advanced and metastatic breast cancer (A/MBC) is changing as new agents are being combined with more established treatments to achieve greater efficacy in combating resistant and unresponsive disease. The present study is designed to describe patient characteristics, treatment patterns, and clinical outcomes in a cohort of women with HR+/HER2- A/MBC treated with palbociclib plus aromatase inhibitor (P+AI) or palbociclib plus fulvestrant (P+FV) in the US community oncology setting.
Methods:
Retrospective medical record data from adult women diagnosed with HR+/HER2- A/MBC who initiated P+AI or P+FV for treatment of A/MBC on or after February 3, 2015 were collected from the Vector Oncology Data Warehouse, a network comprised of 10 community oncology practices across the US. Descriptive analyses were performed on patient characteristics, treatment patterns, and clinical outcomes. Time to event outcomes (progression-free rate (PFR) and survival rate (SR)) at 12 (PFR-12, SR-12) and 24 (PFR-24, SR-24) months for the P+AI combination as first line endocrine therapy and 12 and 18 months for the P+FV combination as treatment following prior endocrine based therapy in either the adjuvant or metastatic setting.
Results:
Among 304 patients who received palbociclib combination therapy, 281 (92.4%) received it per labeled indication. Of the 281 on-label users, the focus of reporting here, 233 (82.9%) received P+AI as their initial endocrine therapy after A/MBC diagnosis; 48 (17.1%) received P+FV after prior endocrine therapy for breast cancer. Patient mean age (SD) was 63.1 (11.4) and 68.2 (10.2) years for patients receiving P+AI and P+FV, respectively. Patients were predominantly white (74.2% for P+AI and 77.1% for P+FV patients).The initial dosing for palbociclib was 125mg/day in 85.4% (n=199) of P+AI and 79.2% (n=38) of P+FV patients. Among patients who received P+AI, PFR-12 was 69.8% and PFR-24 was 46.8% with median follow up time of 10.8 months and 36.8% of progression events. The SR-12 was 89.8% and SR-24 was 71.4%. For patients who received P+FV, PFR-12 was 43.5% and PFR-18 was 39.9% with a median follow up time of 7.6 months and 50.0% of progression events. The SR-12 was 76.3% and SR-18 was 65.0%.
Conclusions:
This study provides real-world assessment of treatment patterns and clinical outcomes of patients with HR+/ HER2- A/MBC who received palbociclib in combination with an AI or a FV in US community oncology settings. These findings demonstrate the benefit of palbociclib combination therapy in a diverse real world population.
