Public perceptions of trophy hunting are pragmatic, not dogmatic.

Fierce international debates rage over whether trophy hunting is socially acceptable, especially when people from the Global North hunt well-known animals in sub-Saharan Africa. We used an online vignette experiment to investigate public perceptions of the acceptability of trophy hunting in sub-Saharan Africa among people who live in urban areas of the USA, UK and South Africa. Acceptability depended on specific attributes of different hunts as well as participants' characteristics.

Caries clusters at lesion-severity thresholds: A Sierra Leone case study.

Objectives: Despite being almost entirely preventable, globally, dental caries is extremely prevalent. Moreover, dental caries will continue to present an even larger challenge for lower income countries, particularly those in the African context, as they transition to a more Western diet. Hence, epidemiological data providing insight into disease patterns and trends is critical to inform public health action.

Oral Health and Community Nursing: a Practical Guide to the Delivering Better Oral Health Toolkit for Adults.

Despite being largely preventable, oral diseases are the major contributor to chronic conditions nationally and globally. If left untreated, oral diseases have many harmful effects throughout life on our patients including pain and infection, and can lead to difficulties with eating, sleeping, socialising and wellbeing. Oral health inequalities exist across our population, and particularly affect vulnerable, disadvantaged and socially excluded groups in society.

The cell envelope of suggests a mechanism for outer membrane biogenesis.

The presence of a cell membrane is one of the major structural components defining life. Recent phylogenomic analyses have supported the hypothesis that the last universal common ancestor (LUCA) was likely a diderm. Yet, the mechanisms that guided outer membrane (OM) biogenesis remain unknown.

The role of chicken management practices in children's exposure to environmental contamination: a mixed-methods analysis.

Background: Household chicken production presents an opportunity to promote child nutrition, but the benefits might be offset by increased environmental contamination. Using household surveys, direct observations, and in-depth interviews with woman caregivers, we sought to describe the relationship between chicken management practices and household exposure to environmental contamination, and assess barriers to adopting improved husbandry practices.

Methods: First, we analyzed baseline data from 973 households raising chickens in the two interventions arms from the Agriculture-to-Nutrition (ATONU) study in Ethiopia to assess the relationship between animal management practices and environmental exposures.

SARS-CoV-2 Serological testing in frontline health workers in Zimbabwe.

Background: In order to protect health workers from SARS-CoV-2, there is need to characterise the different types of patient facing health workers. Our first aim was to determine both the infection status and seroprevalence of SARS-CoV-2 in health workers. Our second aim was to evaluate the occupational and demographic predictors of seropositivity to inform the country's infection prevention and control (IPC) strategy.

Awareness and Understanding of Decision-Making Capacity and Its Relationship to Legally Valid Consent for Older Patients in Dentistry.

With a growing ageing population and increased life expectancy in the UK, oral healthcare professionals will be exposed to a greater number of patients with health conditions which may affect cognitive function, communication and capacity to consent to treatment. This often gives rise to a conundrum which clinicians may face when considering capacity, consent and the legal implications and frameworks surrounding this. Assessing patient capacity is encountered routinely in dental practice and so oral healthcare professionals should be well informed of their responsibilities in this context.

Men's nutrition knowledge is important for women's and children's nutrition in Ethiopia.

In an effort to address undernutrition among women and children in rural areas of low-income countries, nutrition-sensitive agriculture (NSA) and behaviour change communication (BCC) projects heavily focus on women as an entry point to effect nutritional outcomes. There is limited evidence on the role of men's contribution in improving household diets. In this Agriculture to Nutrition trial (Clinicaltrials.

A Chicken Production Intervention and Additional Nutrition Behavior Change Component Increased Child Growth in Ethiopia: A Cluster-Randomized Trial.

Background: Chicken production in the context of nutrition-sensitive agriculture may benefit child nutrition in low-income settings.

Objectives: This study evaluated effects of 1) a chicken production intervention [African Chicken Genetic Gains (ACGG)], and 2) the ACGG intervention with nutrition-sensitive behavior change communication (BCC) [ACGG + Agriculture to Nutrition (ATONU)], on child nutrition and health outcomes and hypothesized intermediaries.

Methods: Forty ACGG villages received 25 genetically improved chickens and basic husbandry guidance; of these, 20 ACGG + ATONU villages in addition received a nutrition-sensitive behavior change and homegardening intervention; 20 control clusters received no intervention.

Bony cystic lesion with associated submandibular lymphadenopathy on a background of breast carcinoma: an unexpected case of cervicofacial actinomycosis.

Actinomycosis is an uncommon, chronic suppurative granulomatous infection and needs to be considered as a differential diagnosis. A 56-year-old woman with a background of type 2 diabetes mellitus and breast carcinoma was referred to the Oral and Maxillofacial Surgery 2-week wait clinic, regarding a tender sublingual mass and firm erythematous swelling in the right submandibular and submental region. This was slowly progressive and had not responded to oral co-amoxiclav.

Consequences Matter: Compassion in Conservation Means Caring for Individuals, Populations and Species.

Human activity affecting the welfare of wild vertebrates, widely accepted to be sentient, and therefore deserving of moral concern, is widespread. A variety of motives lead to the killing of individual wild animals. These include to provide food, to protect stock and other human interests, and also for sport.

Market food diversity mitigates the effect of environment on women's dietary diversity in the Agriculture to Nutrition (ATONU) study, Ethiopia.

Objective: In Ethiopia, women's dietary diversity is low, primarily due to poor food availability and access, both at home and market level. The present study aimed to describe market access using a new definition called market food diversity (MFD) and estimate the impact of MFD, crop and livestock diversity on dietary diversity among women enrolled in the Agriculture to Nutrition (ATONU) trial.

Design: Baseline cross-sectional data collected from November 2016 to January 2017 were used for the analysis.

Bells, bomas and beefsteak: complex patterns of human-predator conflict at the wildlife-agropastoral interface in Zimbabwe.

Reports of livestock depredation by large predators were systematically collected at three study sites in northwestern Zimbabwe from 2008-2013. We recorded 1,527 incidents (2,039 animals killed and 306 injured). Lions () and spotted hyaenas () were mostly responsible, and cattle and donkeys most frequently attacked.

Lateral-flow colloidal gold-based immunoassay for the rapid detection of deoxynivalenol with two indicator ranges.

A lateral-flow immunoassay using a colloidal gold-labelled monoclonal antibody was developed for the rapid detection of deoxynivalenol (DON). Different parameters, such as the amount of immunoreagents, type of the materials, composition of the blocking solution and of the detector reagent mixture, were investigated to provide the optimum assay performance. The experimental results demonstrated that such a visual test had an indicator range rather than a cut-off value.

Development of a colloidal gold-based lateral-flow immunoassay for the rapid simultaneous detection of zearalenone and deoxynivalenol.

A multianalyte lateral-flow technique using colloidal gold-labeled monoclonal antibodies was developed for the rapid simultaneous detection of deoxynivalenol (DON) and zearalenone (ZEA). The results of this qualitative one-step test were interpreted visually. A very simple and fast sample preparation was used, and the assay procedure could be accomplished within 10 min.

Application and validation of a clean-up tandem assay column for screening ochratoxin A in cocoa powder.

A rapid antibody-based assay for the detection of ochratoxin A in cocoa powder is described, involving sequential clean-up and visual detection of the toxin ("clean-up tandem assay column"). The screening test was developed to have a cut-off level of 2 microg kg(-1) and was shown to have false positive and false negative rates of 10 and 2%, respectively. Analysis of six samples can be carried out in the field in approximately 30 min by untrained workers.

Novel developments in rapid mycotoxin detection.

Rapid antibody-based mycotoxin screening techniques are designed to be used outside a laboratory environment, at the place of sampling. Results are expected immediately, so that commodities can be further processed without delay. Because they are used for mycotoxin analysis, very low levels (ppb and ppt range) should be detected.

Evaluation of fumonisin contamination in cornflakes on the Belgian market by "flow-through" assay screening and LC-MS/MS analyses.

A total of 205 cornflake samples collected in Belgian retail stores during 2003-2004 were surveyed for the natural occurrence of fumonisin B1 (FB1), B2 (FB2), and B3 (FB3). These cornflake samples, originating from conventional as well as from organic production, were analyzed using an intralaboratory-validated LC-MS/MS method. Additionally, 90 cornflake samples were subjected to rapid screening using a flow-through enzyme immunoassay method to demonstrate the practicability of a screening test coupled to a validated confirmatory LC-MS/MS method for the management of food safety risks.

Development of an immunoassay-based lateral flow dipstick for the rapid detection of aflatoxin B1 in pig feed.

The aim of this work was to develop an immunoassay-based lateral flow dipstick for the rapid detection of aflatoxin B(1) in pig feed. The test consisted of three main components: conjugate pad, membrane, and absorbent pad. The membrane was coated with two capture reagents, that is, aflatoxin B(1)-bovine serum albumin conjugate and rabbit anti-mouse antibodies.

Development of a solid-phase cleanup and portable rapid flow-through enzyme immunoassay for the detection of ochratoxin a in roasted coffee.

A membrane-based flow-through enzyme immunoassay (patent application pending) for the detection of ochratoxin A (OA) in roasted coffee was developed. First, an extraction and solid-phase cleanup method was developed. A high partition coefficient for OA in the mobile phase was achieved by using methanol/5% aqueous NaHCO(3) as the sample extraction and cleanup solvent.
