Racial and ethnic disparities in the incidence of esophageal cancer have not been thoroughly characterized with quantitative health disparity measures. Using data from 13 cancer registries in the Surveillance, Epidemiology, and End Results database, we assessed such disparities by histological type during 1992-2013 in the United States based on a variety of disparity metrics. The age-standardized incidence rate of squamous cell carcinoma was highest among blacks, while adenocarcinoma mainly affected white men...

BACKGROUND: Rurality and distance from cancer treatment centres have been shown to negatively impact cancer outcomes, but the mechanisms remain obscure. METHODS: We analysed the impact of travel time to key healthcare facilities and mainland/island residency on the cancer diagnostic pathway (treatment within 62 days of referral, and within 31 days of diagnosis) and 1-year mortality using a data-linkage study with 12 339 patients. RESULTS: After controlling for important confounders, mainland patients with more than 60 min of travelling time to their cancer treatment centre ((OR 1...

Iron-gall ink (IGI) has been used by scribes for writing since at least the 4th century CE. Another typical use of this ink was for drawing: many Old Masters created beautiful sketches in brown-black hues. Despite its widespread use to draw lines, it seems like IGI was hardly used for painting as well. In fact, the number of identification on manuscripts is very low at present. This could be partially due to a lack of reliable diagnostic information. In this work we tried to better define the possibility of identifying IGI as a pigment on illuminate manuscripts, evaluating the pros and cons of three different techniques: UV-visible diffuse reflectance spectrophotometry with optic fibres (FORS), Raman spectroscopy and XRF spectrometry...

Photothermal therapy (PTT) has shown significant potential for cancer therapy. However, developing nanomaterials (NMs)-based photothermal agents (PTAs) with satisfactory photothermal conversion efficacy (PTCE) and biocompatibility remains a key challenge. Herein, a new generation of PTAs based on two-dimensional (2D) antimonene quantum dots (AMQDs) was developed by a novel liquid exfoliation method. Surface modification of AMQDs with polyethylene glycol (PEG) significantly enhanced both biocompatibility and stability in physiological medium...

Wellfleet Bay virus (WFBV) is a recently described orthomyxovirus isolated from the tissues of Common Eiders (Somateria mollissima) collected during recurrent mortality events on Cape Cod, Massachusetts, USA. Coastal Massachusetts is the only location where disease or mortality associated with this virus has been detected in wild birds, and a previous seroprevalence study found a significantly higher frequency of viral exposure in eiders from this location than from other areas sampled in North America. This suggests that coastal Massachusetts is an epicenter of WFBV exposure, but the reason for this is unknown...

Endometriosis, a common disorder affecting women of reproductive age is characterized by ectopic growth of the endometrial tissues, altered steroid hormone response and inflammation. Previous studies revealed that statins, selective inhibitors of the key step of mevalonate pathway, inhibit growth of endometrial stromal cells in vitro and reduce endometriotic lesions in murine models of endometriosis. This study evaluated the effects of simvastatin on the development of endometriosis in a baboon model of this disease...

BACKGROUND AND AIMS: Chronic hepatitis C virus (HCV)-related complications have increased over the past decade. METHODS: We used join-point regression modeling to investigate trends in these complications from 2006-2015, and the impact of demographics on these trends. Using data from the Chronic Hepatitis Cohort Study (CHeCS), we identified points at which the trend significantly changed, and estimated the annual percent change (APC) in rates of cirrhosis, decompensated cirrhosis, and all-cause mortality, adjusted by race, sex, and age...

Computational electronic structure calculations are routinely undertaken to predict thermodynamic properties of the various species. However, the application of highly accurate wave function theory methods, such as the "gold standard" coupled cluster approach including single, double and partly triple excitations in perturbative fashion, CCSD(T), to large molecules is limited due to high computational cost. In this work, the promising domain based local pair natural orbital coupled cluster approach, DLPNO-CCSD(T), has been tested to reproduce 113 accurate formation enthalpies of medium-size molecules (few dozens heavy atoms) important for bio- and combustion chemistry via the reaction based Feller-Peterson-Dixon approach...

Introduction Opioid prescribing recently has come under intense scrutiny. However, longitudinal patterns of opioid prescription receipt in a population-based cohort of patients who have chronic pain, such as those with rheumatoid arthritis (RA), have not been well characterized. Methods We identified a cohort of RA patients based on 2006-2014 Medicare data and evaluated longitudinal time trends in regular opioid use (>=3 filled prescriptions in each 12 month interval). A separate analysis in 2014 assessed rheumatologist-specific variability in regular opioid prescription for RA patients...

PURPOSE: Despite the well-established health effects of socioeconomic status (SES), SES resources such as employment may differently influence health outcomes across sub-populations. This study used a national sample of US adults to test if the effect of baseline employment (in 1986) on all-cause mortality over a 25-year period depends on race, gender, education level, and their intersections. METHODS: Data came from the Americans' Changing Lives (ACL) study, which followed 2025 Whites and 1156 Blacks for 25 years from 1986 to 2011...

This paper evaluates variation in food prices within and between neighborhoods to improve our understanding of access to healthy foods in urbanized areas and potential economic incentives and barriers to consuming a higher-quality diet. Prices of a selection of healthier foods (dairy, fruit juice, and frozen vegetables) and unhealthy foods (soda, sweets, and salty snacks) were obtained from 1953 supermarkets across the USA during 2009-2012 and were linked to census block group socio-demographics. Analyses evaluated associations between neighborhood SES and proportion Black/Hispanic and the prices of healthier and unhealthy foods, and the relative price of healthier foods compared with unhealthy foods (healthy-to-unhealthy price ratio)...

Rapid global deforestation has forced many of the world's primates to live in fragmented habitats, making the understanding of their behavioral responses to degraded and fragmented habitats a key challenge for their future protection and management. The black-and-white snub-nosed monkey (Rhinopithecus bieti) is an endangered species endemic to southwest China. The forest habitat ranges from near-continuous to fragmented. In this study, we investigated the activity budget and diet of a R. bieti population that live in an isolated and degraded habitat patch at Mt...

Background -Data from before the 2000s indicate the majority of incident cardiovascular disease (CVD) events occur among US adults with systolic and diastolic blood pressure (SBP/DBP)≥140/90 mmHg. Over the past several decades, BP declined and hypertension control has improved. Methods -We estimated the percentage of incident CVD events that occur at SBP/DBP<140/90 mmHg in a pooled analysis of three contemporary US cohorts: the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, the Multi-Ethnic Study of Atherosclerosis (MESA), and the Jackson Heart Study (JHS) (n=31,856; REGARDS=21,208; MESA=6,779; JHS=3,869)...

Development of speech and language is rapid in early years, yet if developmental problems in speech and language are not addressed they are likely to continue and impact negatively on a child's overall development and their life trajectory. Children who have experienced abuse and or neglect are particularly vulnerable. The aim of this study was to develop a tool to assist in identifying a child's need for assessment by a speech pathologist so that there could be early identification of problems. A culturally sensitive tool was developed to be completed by the child's carer included questions on language, speech and hearing, voice, fluency, understanding sentences, vocabulary and expression...
