The spatiotemporal variability of ambient volatile organic compounds (VOCs) in Tehran, Iran, is not well understood. Here we present the design, methods, and results of the Tehran Study of Exposure Prediction for Environmental Health Research (Tehran SEPEHR) on ambient concentrations of benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene (BTEX), and total BTEX. To date, this is the largest study of its kind in a low- and middle-income country and one of the largest globally. We measured BTEX concentrations at five reference sites and 174 distributed sites identified by a cluster analytic method...

Erik Schokkaert, Jonas Steel, Carine Van de Voorde
We present a critical review of the literature that discusses the link between the level of out-of-pocket payments in developed countries and the share of people in these countries reporting that they postpone or forgo healthcare for financial reasons. We discuss the pros and cons of measuring access problems with this subjective variable. Whereas the quantitative findings in terms of numbers of people postponing care must be interpreted with utmost caution, the picture for the vulnerable groups in society is reasonably robust and unsurprising: people with low incomes and high morbidity and incomplete (or non-existent) insurance coverage are most likely to postpone or forgo healthcare for financial reasons...

For high-risk low-grade gliomas (LGGs), adjuvant radiotherapy (RT) with procarbazine/lomustine/vincristine (PCV) chemotherapy increases overall survival (OS) over RT alone. However, in practice, temozolomide (TMZ) is often used instead of PCV. Using the National Cancer Data Base (NCDB), we provide the first investigation of practice patterns and outcomes of chemoradiotherapy with single-agent chemotherapy (SAC, analogous to TMZ) or multi-agent chemotherapy (MAC, analogous to PCV) for LGG. Patients with high-risk Grade II LGGs were queried in the NCDB...

PURPOSE: Parallel to increasing survival of breast cancer (BC) patients, a need has arisen to characterize the follow-up required to improve and maintain their health. Our study aimed to assess changes in lifestyle habits over time among the study population, compare compliance rates of selected primary and secondary prevention practices between long-term BC survivors and an age-matched comparison group, and identify factors associated with compliance to these practices. METHODS: The study population comprised 250 Israeli BC survivors, diagnosed with BC between 1999 and 2003, without evidence of disease after 8-12 years, and 250 women with no cancer history, individually matched to survivors by age and area of residence...

INTRODUCTION: The availability of tobacco is thought to influence smoking behaviour, but there are few longitudinal studies examining if the location and number of tobacco outlets has a prospective impact on smoking cessation. METHODS: The Ontario Tobacco Survey, a population-representative sample of Ontario adult smokers who were followed every 6 months for up to 3 years, was linked with tobacco outlet location data from the Ontario Ministry of Health. Proximity (distance), threshold (at least one outlet within 500 m) and density (number of outlets within 500 m) with respect to a smokers' home were calculated among urban and suburban current smokers (n=2414)...

BACKGROUND: Depression is a common health condition affecting up to a third of patients attending primary care, where most of the care for people with depression is provided. Adequate recognition of depression is the critical step in the path to effective care, particularly in low income countries. As part of the Programme for Improving Mental healthcare (PRIME), a project supporting the implementation of integrated mental healthcare in primary care, we evaluated the level of recognition of depression by clinicians working in primary care in rural Ethiopia prior to in service training...

BACKGROUND: Migrants resident in Italy exceeded 5 million in 2015, representing 8.2% of the resident population. The study of the mechanisms that explain the differential health of migrant workers (as a whole and for specific nationalities) has been identified as a priority for research. The international literature has shown that migrant workers have a higher risk of total and fatal injury than natives, but some results are conflicting. The aim of this paper is to study the injury risk differentials between migrants, born in countries with strong migratory pressure (SMPC), and workers born in high income countries (HIC), taking into account individual and firm characteristics and job tenure...

BACKGROUND: Childhood maltreatment is linked with increased risk for mental illness in adolescence and adulthood. However, little evidence is available on whether different forms of maltreatment have specific effects, and no prospective studies in low- or middle-income countries have addressed this issue. METHODS: Participants in a population-based, birth cohort study in Pelotas, Brazil (N=3715) self-reported exposure to maltreatment (emotional abuse, physical neglect, physical abuse, sexual abuse, domestic violence) in confidential questionnaires at age 15 years, and were assessed for major depression in interviews at age 18 years, using the MINI...

Sorghum plants grown with 5mM (NH4)2SO4 showed symptoms of stress, such as reduced growth and photosynthesis, leaf chlorosis, and reddish roots. Phosphoenolpyruvate carboxylase (PEPC) activity, by supplying carbon skeletons for ammonium assimilation, plays a pivotal role in tolerance to ammonium stress. This work investigated the effect of ammonium nutrition on PPC and PPCK gene expression, on PEPC activity, and on post-translational modifications (PTMs) of PEPC in leaves and roots of sorghum plants. Ammonium increased PEPC kinase (PEPCk) activity and the phosphorylation state of PEPC in leaves, both in light and in the dark, due to increased PPCK1 expression in leaves...

This study aims to evaluate the effects of a community-based counselling intervention to improve contraception use among immigrant and native residents in deprived neighbourhoods. : Randomized controlled trial. Women aged 14-49 years and men aged 14-39 years from two low-income neighbourhoods with high proportion of immigration in Barcelona (Catalonia, Spain) who had not undergone irreversible contraception and were not planning a pregnancy were recruited (2011-13). A culturally developed and theoretically based brief counselling intervention was delivered in community settings...

Aims: To identify a typology of heavier drinking styles in Great Britain and to identify socio-demographic trends in the typology over the period 1978-2010. Methods: We applied multiple correspondence analysis and agglomerative hierarchical clustering to beverage-specific quantity-frequency measures of alcohol consumption in the repeated cross-sectional General Lifestyle Survey of Great Britain, 1978-2010. The cluster analysis focuses on the 60,043 adult respondents over this period reporting average drinking levels above the UK Government guidelines...

The amount of family financial resources available in early life influences child health and development. Using data from the 2000 and 2007 waves of the Indonesian Family Life Survey, we estimated the associations of early-life poverty (at age <7 years) and poverty in later childhood (at age 7-14 years) with cognitive function at age 7-14 years. Our analysis provided little support for the idea that an early intervention to support household income has a larger effect than intervention later in childhood; both seemed equally important...

The Repayment Policy for Multiple Loans is about a given set of loans and a monthly incoming cash flow: what is the best way to allocate the monthly income to repay such loans? In this article, we close the almost 20-year-old open question about how to model the repayment policy for multiple loans problem together with its computational complexity. Thus, we propose a mixed integer linear programming model that establishes an optimal repayment schedule by minimizing the total amount of cash required to repay the loans...

Epidemiological studies have reported associations between traditional cardiovascular risk factors and carotid intima-media thickness (CIMT) or carotid plaque. However, definite risk factors at different phases of carotid atherosclerosis remain controversial. We aimed to explore risk factors and characteristics of carotid atherosclerosis at different stages in a low-income population with a high incidence of stroke in China. Between April 2014 and January 2015, we recruited 3789 stroke-free and cardiovascular disease-free residents aged ≥ 45 years...

The pyramid wavefront sensor (PWFS) is a novel wavefront sensor with several inspiring advantages compared with Shack-Hartmann wavefront sensors. The PWFS uses four pupil images to calculate the local tilt of the incoming wavefront. Pupil images are conjugated with a telescope pupil so that each pixel in the pupil image is diffraction-limited by the telescope pupil diameter, thus the sensing error of the PWFS is much lower than that of the Shack-Hartmann sensor and is related to the extraction and alignment accuracy of pupil images...

This study investigated the gender differences in use of traditional and complementary medicine (TCM) in Ghana. Using an interviewer-administered questionnaire, we collected data from March to June 2013 from 324 randomly sampled adults in the Ashanti Region. The prevalence of TCM use in the prior 12 months was 86%. Females constituted the majority (61%) of TCM users. Female TCM users were more likely than male users to have had only a basic education, been traders (p ˂ .0001), and had health insurance (p ˂ ...
