Health risk assessment of potassium bromate in bread in Ghana.

Introduction: Potassium bromate (KBrO) is an oxidizing agent added to flour to improve bread quality. However, KBrO is nephrotoxic, and a class B carcinogen banned in most countries, including Ghana.

Aim: This study aimed to determine the residual KBrO concentration in bread and to estimate the chemical and carcinogenic risk that is associated with the consumption of these breads in Ghana.

Levelling up health in the early years: A cost-analysis of infant feeding and healthcare.

Background: Although breastfeeding is recommended as the optimal form of nutrition in the first six months, it is not sustained as the predominant mode of feeding infants in Scotland. This study estimated the impact of infant feeding choices on primary and secondary healthcare service costs in a 13-year birth cohort.

Method: Using linked administrative datasets, in a retrospective cohort design of 502,948 singletons born in Scotland between 1997 and 2009, we estimated the cost of GP consultations and hospital admissions by area deprivation and mode of infant feeding up to 6-8 weeks for ten common childhood conditions from birth to 27 months.

Inshore and offshore marine migration pathways of Atlantic salmon post-smolts from multiple rivers in Scotland, England, Northern Ireland, and Ireland.

The migratory behavior of Atlantic salmon (Salmo salar) post-smolts in coastal waters is poorly understood. In this collaborative study, 1914 smolts, from 25 rivers, in four countries were tagged with acoustic transmitters during a single seasonal migration. In total, 1105 post-smolts entered the marine study areas and 438 (39.

Arm cycle ergometry in critically ill patients: A systematic review.

Background: Intensive care unit (ICU) survivors face functional limitations due to ICU-acquired weakness. Arm cycle ergometry (ACE) introduced in the ICU may improve physical function. To our knowledge, there is limited evidence on the effectiveness of ACE and physical function outcomes in critically ill patients.

Patient-oriented research: An essential driver of learning health system capacity development.

Canada's health system faces a lag in implementing high-quality evidence and research-driven innovation into service delivery, while demonstrating accountability and benefit to the public. To address these challenges, Patient-Oriented Research (POR) builds teams that engage researchers, healthcare providers, decision-makers, and most importantly, patients (people with lived and living experience) in the process of generating and applying evidence to inform health services and decision-making. A Learning Health System (LHS) systematically integrates external evidence with internal data and experience and puts that knowledge into practice in a continuous cycle.

The role of body size and cuticular hydrocarbons in the desiccation resistance of invasive Argentine ants (Linepithema humile).

An insect's cuticle is typically covered in a layer of wax prominently featuring various hydrocarbons involved in desiccation resistance and chemical communication. In Argentine ants (Linepithema humile), cuticular hydrocarbons (CHCs) communicate colony identity, but also provide waterproofing necessary to survive dry conditions. Theory suggests different CHC compound classes have functional trade-offs, such that selection for compounds used in communication would compromise waterproofing, and vice versa.

The weird eusociality of polyembryonic parasites.

Some parasitoid wasps possess soldier castes during their parasitic larval stage, but are often neglected from our evolutionary theories explaining caste systems in animal societies. This is primarily due to the polyembryonic origin of their societies. However, recent discoveries of polyembryonic trematodes (i.

The Ant Who Cried Wolf? Short-Term Repeated Exposure to Alarm Pheromone Reduces Behavioral Response in Argentine Ants.

In this study we test whether Argentine ants () progressively reduce their response to a salient stimulus (alarm pheromone) with increased exposure over time. First, we used a two-chamber olfactometer to demonstrate three focal behaviors of Argentine ants that indicate an alarmed state in response to conspecific alarm pheromone and pure synthetic iridomyrmecin (a dominant component of alarm pheromone). We then measured how these behaviors changed after repeated exposure to conspecific alarm pheromone from live ants.

Changing mortality trends in countries and cities of the UK: a population-based trend analysis.

Objectives: Previously improving life expectancy and all-cause mortality in the UK has stalled since the early 2010s. National analyses have demonstrated changes in mortality rates for most age groups and causes of death, and with deprived populations most affected. The aims here were to establish whether similar changes have occurred across different parts of the UK (countries, cities), and to examine cause-specific trends in more detail.

Does ethnic diversity explain intra-UK variation in mortality? A longitudinal cohort study.

Objectives: It has been proposed that part of the explanation for higher mortality in Scotland compared with England and Wales, and Glasgow compared with other UK cities, relates to greater ethnic diversity in England and Wales. We sought to assess the extent to which this excess was attenuated by adjusting for ethnicity. We additionally explored the role of country of birth in any observed differences.

The Development of VegEze: Smartphone App to Increase Vegetable Consumption in Australian Adults.

Background: Poor-quality dietary patterns are often characterized by inadequate consumption of fruits and vegetables. Changing dietary behavior is difficult, and although it is often clear what needs to change, how to enact change is more difficult. Smartphones have characteristics that may support the complexity of changing dietary behavior.

Impact of maternal smoking on early childhood health: a retrospective cohort linked dataset analysis of 697 003 children born in Scotland 1997-2009.

Objective: Smoking during pregnancy is associated with adverse health impacts on mother and child. We used a large linked Scottish dataset to produce contemporary estimates of the impact on child health, particularly hospitalisation.

Design: Retrospective cohort study linking birth, death, maternity, infant health, child health surveillance and admission records.

Desiccation Resistance and Micro-Climate Adaptation: Cuticular Hydrocarbon Signatures of Different Argentine Ant Supercolonies Across California.

Cuticular hydrocarbons (CHCs), the dominant fraction of the insects' epicuticle and the primary barrier to desiccation, form the basis for a wide range of chemical signaling systems. In eusocial insects, CHCs are key mediators of nestmate recognition, and colony identity appears to be maintained through a uniform CHC profile. In the unicolonial Argentine ant Linepithema humile, an unparalleled invasive expansion has led to vast supercolonies whose nestmates can still recognize each other across thousands of miles.

How do community pharmacists make decisions? Results of an exploratory qualitative study in Ontario.

Background: As the complexity of pharmacy practice increases, pharmacists are required to make more decisions under ambiguous or information-deficient conditions. There is scant literature examining how pharmacists make decisions and what factors or values influence their choices. The objective of this exploratory research was to characterize decision-making patterns in the clinical setting of community pharmacists in Ontario.

Regional alcohol consumption and alcohol-related mortality in Great Britain: novel insights using retail sales data.

Background: Regional differences in population levels of alcohol-related harm exist across Great Britain, but these are not entirely consistent with differences in population levels of alcohol consumption. This incongruence may be due to the use of self-report surveys to estimate consumption. Survey data are subject to various biases and typically produce consumption estimates much lower than those based on objective alcohol sales data.

Breastfeeding is associated with reduced childhood hospitalization: evidence from a Scottish Birth Cohort (1997-2009).

Objective: To evaluate the risk of childhood hospitalization associated with infant feeding patterns at 6-8 weeks of age in Scotland.

Study Design: A retrospective population level study based on the linkage of birth, death, maternity, infant health, child health surveillance, and admission records for children born as single births in Scotland between 1997 and 2009 (n = 502 948) followed up to March 2012. Descriptive analyses, Kaplan Meier tests, and Cox regression were used to quantify the association between the mode of infant feeding and risk of childhood hospitalization for respiratory, gastrointestinal, and urinary tract infections, and other common childhood ailments during the study period.

Informing the 'early years' agenda in Scotland: understanding infant feeding patterns using linked datasets.

Background: Providing infants with the 'best possible start in life' is a priority for the Scottish Government. This is reflected in policy and health promotion strategies to increase breast feeding, which gives the best source of nutrients for healthy infant growth and development. However, the rate of breast feeding in Scotland remains one of the lowest in Europe.

Innovative developments for long-term mammalian pest control.

Background: Invasive mammalian pests have inflicted substantial environmental and economic damage on a worldwide scale.

Results: Over the last 30 years there has been minimal innovation in the development of new control tools. The development of new vertebrate pesticides, for example, has been largely restricted due to the costly and time-consuming processes associated with testing and registration.

Has Scotland always been the 'sick man' of Europe? An observational study from 1855 to 2006.

Background: Scotland has been dubbed 'the sick man of Europe' on account of its higher mortality rates compared with other western European countries. It is not clear the length of time for which Scotland has had higher mortality rates. The root causes of the higher mortality in Scotland remain elusive.

Epidemiology of hospitalization due to alcohol-related harm: evidence from a Scottish cohort study.

Objective: To examine a broad range of risk factors and their association with alcohol-related hospital admissions in a Scottish general population.

Design: Observational record-linkage study in Scotland from 1998 to 2008 involving 8305 respondents aged 16-74 years who participated in the 1998 Scottish Health Survey. Outcome was defined as first-time hospital admission with at least one alcohol-related diagnosis.
