MANURE BMP ADOPTION AMONG NORTH DAKOTA ANIMAL FEED OPERATIONS

Regulations governing animal waste storage are primarily a state-level issue. Protecting water resources from animal waste contamination will depend upon how effective state-level animal waste regulations are in encouraging livestock producers to handle waste appropriately. Survey results from North Dakota indicate beef cattle feeding operations do not always comply with state regulations requiring adoption of manure storage BMP's. This is most likely due to incomplete inspection schedules by the regulatory agency. Statistical results suggest herd size plays a much larger role than regulation in promoting adoption of manure storage BMP's.Livestock Production/Industries,

Lower Limb Radiology of Distal Myopathy due to the S60F Myotilin Mutation

Distal myopathies are a clinically and genetically heterogenous group of disorders in which the distal limb musculature is selectively or disproportionately affected. Precisely defining specific categories is a challenge because of overlapping clinical phenotypes, making it difficult to decide which of the many known causative genes to screen in individual cases. In this study we define the distinguishing magnetic resonance imaging findings in myotilin myopathy by studying 8 genealogically unrelated cases due to the same point mutation in TTID. Proximally, the vastii, biceps femoris and semimembranosus were involved with sparing of gracilis and sartorius. Distally, soleus, gastrocnemius, tibialis anterior, extensor hallicus and extensor digitorum were involved. This pattern contrasts with other distal myopathies and provides further support for the role of imaging in the clinical investigation of muscle disease. Copyright (C) 2009 S. Karger AG, Base

Formulation of hydrophobic peptides for skin delivery via coated microneedles

Microneedles (MNs) have been investigated as a minimally-invasive delivery technology for a range of active pharmaceutical ingredients (APIs). Various formulations and methods for coating the surface of MNs with therapeutics have been proposed and exemplified, predominantly for hydrophilic drugs and particulates. The development of effective MN delivery formulations for hydrophobic drugs is more challenging with dosing restrictions and the use of organic solvents impacting on both the bioactivity and the kinetics of drug release. In this study we propose a novel formulation that is suitable for MN coating of hydrophobic auto-antigen peptides currently being investigated for antigen specific immunotherapy (ASI) of type 1 diabetes. The formulation, comprising three co-solvents (water, 2-methyl-2-butanol and acetic acid) and polyvinylalcohol 2000 (PVA2000) can dissolve both hydrophilic and hydrophobic peptide auto-antigens at relatively high, and clinically relevant, concentrations (25 mg/ml or 12.5 mg/ml). The drug:excipient ratio is restricted to 10:1 w/w to maximise dose whilst ensuring that the dry-coated payload does not significantly impact on MN skin penetration performance. The coating formulation and process does not adversely affect the biological activity of the peptide. The delivery efficiency of the coated peptide into skin is influenced by a number of parameters. Electropolishing the metal MN surface increases delivery efficiency from 2.0 ± 1.0% to 59.9 ± 6.7%. An increased mass of peptide formulation per needle, from 0.37 μg to 2 μg peptide dose, resulted in a thicker coating and a 20% reduction in the efficiency of skin delivery. Other important performance parameters for coated MNs include the role of excipients in assisting dissolution from the MNs, the intrinsic hydrophobicity of the peptide and the species of skin model used in laboratory studies. This study therefore both exemplifies the potential of a novel formulation for coating hydrophobic and hydrophilic peptides onto MN devices and provides new insight into the factors that influence delivery efficiency from coated MNs. Importantly, the results provide guidance for identifying critical attributes of the formulation, coating process and delivery device, that confer reproducible and effective delivery from coated MNs, and thus contribute to the requirements of the regulators appraising these devices

Older adults experiences of rehabilitation in acute health care

Rehabilitation is a key component of nursing and allied healthcare professionals’ roles in most health and social care settings. This paper reports on stage 2 of an action research project to ascertain older adult's experience of rehabilitation. Twenty postdischarge interviews were conducted and the interview transcripts were analysed using thematic content analysis. All older adults discharged from an acute older acute rehabilitation ward to their own homes in the community were eligible to participate. The only exclusion criterion was older adults who were thought to be unable to give consent to participate by the nurse in charge and the researcher. Whilst 92 older adults were eligible to participate in this research study, only 20 were interviewed. The findings from this study suggest that older adults valued communication with health professionals but were aware of their time constraints that hindered communication. This study suggests that both nurses and allied health professionals are not actively providing rehabilitative services to promote health and well-being, which contradicts the focus of active ageing. Furthermore, there was evidence of unmet needs on discharge, and older adults unable to recall the professions that were involved in their interventions and the rationale for therapy input. It is suggested that further research is needed to explore the effectiveness of allied health rehabilitation in the acute setting. This study highlights the need for further research into older adults’ perceptions of the rehabilitation process in the acute setting
