Understanding how and why users might use NHS repositories: A mixed methods study.

Background: There is little evidence on the use or potential use of NHS repositories within the UK.

Methods: A mixed methods (quantitative/qualitative) study of two repositories: amber-the home of ambulance service research, and East Midlands Evidence Repository (EMER). A structured online questionnaire was distributed via the repository home page, and promoted via social media, email networks, and lists.

Methods for Studying Motor-Driven Viral DNA Packaging in Bacteriophages phi29, Lambda, and T4 via Single DNA Molecule Manipulation and Rapid Solution Exchange.

Viral DNA packaging is a required step in the assembly of many dsDNA viruses. A molecular motor fueled by ATP hydrolysis packages the viral genome to near crystalline density inside a pre-formed prohead shell in ~5 min at room temperature in vitro. We describe procedures for measuring the packaging of single DNA molecules into single viral proheads with optical tweezers.

Pressure ulcer prevention for people with long-term neurological conditions (LTNCs) who self-manage care and live at home.

Aim: To develop a Theory of Change (ToC) pathway to facilitate the development of a multi-component intervention package supporting pressure Ulcer (PU) risk identification and management, in partnership with people with Long Term Neurological Conditions (LTNC) who self-manage care and live at home, their informal carers and PAs.

Methods: A participatory approach, with extensive input from those whose lives are the focus of the research, was used throughout the 4 interlinked work packages (WP): Iterative data analysis was undertaken with emerging findings from each WP informing subsequent stages of the study.

Findings: Overall, 74 participants contributed across the 4 WPs, incorporating 31 Service Users (SU), 8 carers, 9 Personal Assistants (PAs) and 26 professional stakeholders.

Ligand Chirality Transfer from Solution State to the Crystalline Self-Assemblies in Circularly Polarized Luminescence (CPL) Active Lanthanide Systems.

The synthesis of a family of chiral and enantiomerically pure pyridyl-diamide (pda) ligands that upon complexation with europium [Eu(CFSO)] result in chiral complexes with metal centered luminescence is reported; the sets of enantiomers giving rise to both circular dichroism (CD) and circularly polarized luminescence (CPL) signatures. The solid-state structures of these chiral metallosupramolecular systems are determined using X-ray diffraction showing that the ligand chirality is transferred from solution to the solid state. This optically favorable helical packing arrangement is confirmed by recording the CPL spectra from the crystalline assembly by using steady state and enantioselective differential chiral contrast (EDCC) CPL Laser Scanning Confocal Microscopy (CPL-LSCM) where the two enantiomers can be clearly distinguished.

The Role of Civil Society in Mobilizing Human Rights Struggles for Essential Medicines: A Critique from HIV/AIDS to COVID-19.

In this paper, we explore the strategies utilized by civil society organizations to improve access to medicines during the HIV/AIDS and COVID-19 health crises. In particular, we seek to illuminate why some of the successful approaches for increasing access to antiretrovirals for HIV/AIDS in the early 2000s failed in creating equitable global access to COVID-19 vaccines. While civil society has historically mobilized human rights to facilitate greater access to essential medicines, we argue that earlier strategies were not always sustainable and that civil society is now mobilizing human rights in radically different ways than previously.

Should COVID-19 Vaccines Authorized for Emergency Use Be Considered "Essential" Medicines?

A critical debate in the race to develop, market, and distribute COVID-19 vaccines could define the future of this pandemic: How much evidence demonstrating a vaccine's safety and efficacy should be required before it is considered "essential"? If a COVID-19 vaccine were to be designated an essential medicine by the World Health Organization, this would invoke special "core" human rights duties for governments to provide the vaccine as a matter of priority irrespective of resource constraints. States would also have duties to make the vaccine available in adequate amounts, in the appropriate dosage forms, with assured quality and adequate information, and at an affordable price. This question is especially critical and unique given that COVID-19 vaccines have in many cases been authorized for use via national emergency use authorization processes-mechanisms that enable the public to gain access to promising medical products before they have received full regulatory approval and licensure.

Using crime script analysis to understand wildlife poaching in Vietnam.

Poaching can contribute to the failure of biodiversity conservation efforts and inflict diverse harms on human livelihoods. We applied crime script analysis to the case of snare poaching-an illegal hunting activity-in three Vietnamese protected areas. Our goal was to enhance the understanding about the opportunity structure underlying snare poaching to advance the suite of community-based crime prevention activities.

An intersectional human rights approach to prioritising access to COVID-19 vaccines.

We finally have a vaccine for the COVID-19 crisis. However, due to the limited numbers of the vaccine, states will have to consider how to prioritise groups who receive the vaccine. In this paper, we argue that the practical implementation of human rights law requires broader consideration of intersectional needs in society and the disproportionate impact that COVID-19 is having on population groups with pre-existing social and medical vulnerabilities.

A Severe Lack of Evidence Limits Effective Conservation of the World's Primates.

Threats to biodiversity are well documented. However, to effectively conserve species and their habitats, we need to know which conservation interventions do (or do not) work. Evidence-based conservation evaluates interventions within a scientific framework.

Monitoring occurrence, extinction, and colonization probabilities for gibbon populations.

All gibbon species (Family: Hylobatidae) are considered threatened with extinction and recognized on the International Union for Conservation of Nature Red List of Threatened Species. Because gibbons are one of the most threatened families of primates, monitoring their status is now critically important. Long-term monitoring programs applying occupancy approaches, in addition to assessing occurrence probability, improves understanding of other population parameters such as site extinction or colonization probabilities, which elucidate temporal and spatial changes and are therefore important for guiding conservation efforts.

Platelet-Rich Plasma and Epidural Platelet Lysate: Novel Treatment for Lumbar Disk Herniation.

Lumbar herniated disks present a common cause of significant axial low back and radiating leg pain. This situation poses a risk for potentially permanent neurologic compromise, including numbness, weakness, and bowel and bladder dysfunction. Traditional treatment strategies such as medications, epidural steroids, and surgery all carry potential risk for iatrogenic sequelae.

Habitat degradation and indiscriminate hunting differentially impact faunal communities in the Southeast Asian tropical biodiversity hotspot.

Habitat degradation and hunting have caused the widespread loss of larger vertebrate species (defaunation) from tropical biodiversity hotspots. However, these defaunation drivers impact vertebrate biodiversity in different ways and, therefore, require different conservation interventions. We conducted landscape-scale camera-trap surveys across six study sites in Southeast Asia to assess how moderate degradation and intensive, indiscriminate hunting differentially impact tropical terrestrial mammals and birds.

PQS Produced by the Pseudomonas aeruginosa Stress Response Repels Swarms Away from Bacteriophage and Antibiotics.

We investigate the effect of bacteriophage infection and antibiotic treatment on the coordination of swarming, a collective form of flagellum- and pilus-mediated motility in bacteria. We show that phage infection of the opportunistic bacterial pathogen abolishes swarming motility in the infected subpopulation and induces the release of the quinolone signaling molecule PQS, which repulses uninfected subpopulations from approaching the infected area. These mechanisms have the overall effect of limiting the infection to a subpopulation, which promotes the survival of the overall population.

Outcomes after implementing restrictive blood transfusion criteria in extremely premature infants.

Objective: To assess mortality and morbidities in very low birthweight (VLBW) infants before and after changing to a restrictive blood transfusion guideline (RTG).

Study Design: This is a large retrospective study comparing outcomes of a liberal transfusion guideline (LTG) and RTG in VLBW infants admitted to a large single neonatal intensive care unit. Blood and platelet transfusion details, mortality, and diagnoses of frequently diagnosed morbidities were collected for each infant.

Surgery for tennis elbow: a systematic review.

Background: There is no consensus on the most suitable treatment for tennis elbow but, in the USA, surgical intervention is increasing despite a lack of supportive research evidence. The aim of this systematic review was to provide a balanced update based on all relevant published randomized controlled trials conducted to date.

Methods: An electronic search of MEDLINE, EMBASE, CINAHL, BNI, AMED, PsycINFO, HBE, HMIC, PubMed, TRIP, Dynamed Plus and The Cochrane Library was complemented by hand searching.

Recovery planning towards doubling wild tiger Panthera tigris numbers: Detailing 18 recovery sites from across the range.

With less than 3200 wild tigers in 2010, the heads of 13 tiger-range countries committed to doubling the global population of wild tigers by 2022. This goal represents the highest level of ambition and commitment required to turn the tide for tigers in the wild. Yet, ensuring efficient and targeted implementation of conservation actions alongside systematic monitoring of progress towards this goal requires that we set site-specific recovery targets and timelines that are ecologically realistic.

An Efficient Acoustic Density Estimation Method with Human Detectors Applied to Gibbons in Cambodia.

Some animal species are hard to see but easy to hear. Standard visual methods for estimating population density for such species are often ineffective or inefficient, but methods based on passive acoustics show more promise. We develop spatially explicit capture-recapture (SECR) methods for territorial vocalising species, in which humans act as an acoustic detector array.

Phylogeny and distribution of crested gibbons (genus Nomascus) based on mitochondrial cytochrome b gene sequence data.

Crested gibbons, genus Nomascus, are endemic to the Indochinese bioregion and occur only in Vietnam, Laos, Cambodia, and southern China. However, knowledge about the number of species to be recognized and their exact geographical distributions is still limited. To further elucidate the evolutionary history of crested gibbon species and to settle their distribution ranges, we analyzed the complete mitochondrial cytochrome b gene from 79 crested gibbon individuals from known locations.

Infection prevention and control learning preferences of nurses sampled at a teaching hospital.

A pilot study was conducted within the medical-surgical intensive care unit (MSICU) of the Toronto General Hospital site of the University Health Network during the winter/spring (March-June) of 1999 to examine nurses' learning preferences relevant to infection prevention and control (IPAC). The majority of the nurses sampled indicated a preference for face-to-face infection prevention and control education (seminars). Such seminars were preferred on an annual basis by most respondents.

Impact on HIV test providers of giving a positive test result.

The provision of a positive HIV antibody test result and the direction and support given to the test recipient are critical components of care and prevention. There has been little research that describes what happens in such interactions between recipient and provider. The impact on the test provider of delivering the HIV test result is an important issue to consider.

Internal contamination of gloves: routes and consequences.

The effect of internal glove contamination was investigated using N-methyl pyrrolidone (NMP) as a biological marker to assess systemic absorption when wearing internally contaminated gloves, and when not wearing gloves but subjected to the same challenge contaminant. The routes by which the insides of gloves become contaminated were also investigated. The area of dermal contamination was quantified using a fluorescent tracer dye and a surface monitoring fluorimeter.

Aiming for Prevention: international medical conference on small arms, gun violence and injury.

IPPNW and Physicians for Social Responsibility, Finland organized an international conference on small arms and firearms injury in Helsinki from 28-30 September 2001, emphasizing the preventive medicine aspects of the issues discussed. This article describes the background to this conference and reports the work of IPPNW in following it up.

Aiming for prevention: medical and public health approaches to small arms, gun violence, and injury.

The level of global small arms violence is enormous and the scale of human suffering it causes is immense, although poorly counted. It causes at least hundreds of thousands of deaths and more than a million injuries each year, as well as permanent physical and psychological damage, destruction of families, lost productivity, and diversion of resources from basic health services. Research is required on three basic issues, as follows: health effects of weapons; the contributing factors and causes, including behavioral issues; and impacts of interventions and their cost-effectiveness.
