The association between herd- and cow-level factors and somatic cell count of Irish dairy cows

peer-reviewedSomatic cell count (SCC) is an indicator of both udder health and milk quality and is measured at an animal level through national milk recording schemes. The objective of this study was to assess the animal and herd factors contributing to elevated SCC (i.e. poorer milk quality). Test day records (n = 2,658,928) from 519,456 cow lactations obtained between 2007 and 2011 were included in the analyses. Herd factors tested included the geographical region of the herd and production system operated (spring calving or mixed calving system). Animal factors tested included breed, parity and age nested within parity. Four definitions of normalised SCC (i.e. SCS) were considered: 1) average test-day SCS within a 24 hour period (TD_SCS), 2) maximum SCS (peak_SCS), 3) minimum SCS (min_SCS), and 4) average SCS (avg_SCS) recorded across cow lactation; in addition, the proportion of test day records with an SCC count >200,000 (prop_200) or >250,000 (prop_250) within cow lactation were included. Following adjustment for fixed effects, average TD_SCS was 179,308 cells per mL while avg_SCS, and average min_SCS and peak_SCS were 119,481, 50,992 and 298,813 cells per mL, respectively. All animal and herd factors had a significant effect on SCC. Older animals, animals which were younger at calving than contemporaries and Holstein animals had higher SCC than younger alternative breed animals who calved at the median age. In addition, mixed calving production systems and herds in Connaught had higher SCC than spring calving herds in the other regions of Ireland.The authors gratefully acknowledge funding for this work from the Department of Agriculture, Fisheries and Food under the Joint FIRM / RSF Initiative (Project Number: 10/RD/AAQUALITYMILK/ TMFRC713)

Filling in the Gap: A quantitative analysis of dental restoration types among body donors of Asian descent at the Mann-Labrash Osteological Collection

The Mann-Labrash Osteological Collection at the University of Hawai’i John A. Burns School of Medicine houses over 230 skeletal remains amassed through the Willed Body Program. Of these donors, seventy-eight were of East and Southeast Asian American and Pacific Islander descent. This unique collection offers an exciting opportunity for skeletal analyses of these populations left understudied in the body of anthropological scientific literature. This thesis explores the dietary causes of dental disease and dental restorations from the past to the present. Additionally, macroscopic analyses and Chi-square statistical tests determined which sex cohorts utilized dental restorative prostheses in life. Also addressed are the socioeconomic determinants of dental care access among these underrepresented groups. Lastly, because of the marginal availability of East and Southeast Asian American and Pacific Islander skeletal remains in US reference collections, an examination of death ideologies and organ donor hesitancies held by these communities are reviewed

Outcomes of pulmonary rehabilitation for COPD in older patients: a comparative study

Pulmonary rehabilitation (PR) is established as an effective intervention in optimising function and quality of life in patients with chronic obstructive pulmonary disease (COPD). However, there are very limited data on the effectiveness of PR in older patients with COPD. We reviewed all patients attending an 8-week outpatient programme. Patients were divided into two groups; Group A (n = 202), below 70 years, and Group B (n = 122), above 70 years of age. Outcomes in both patient subgroups were compared using FEV1, Incremental Shuttle Walk Test (ISWT), Endurance Shuttle Walk Test (ESWT), Grip Strength, St. George's Respiratory Questionnaire (SGRQ), Hospital Anxiety and Depression Score (HADS), and COPD Assessment Test (CAT) score. Statistical analysis was conducted using Mann-Whitney non-parametric testing and chi-square testing for comparison of clinically relevant improvements between groups. There was no significant difference in PR outcomes between Group A and Group B using absolute values. Mean changes in ISWT for Groups A and B 39.7 m vs. 32.8 m (p = 0.63), respectively, SGRQ −2.5 vs. −2.8 (p = 0.95), HADS anxiety score −0.83 vs. −0.57 (p = 0.43) and HADS depression score −0.69 vs. −0.39 (p = 0.48), respectively. There was no difference in the proportion of patients who achieved the minimal clinically significant improvement in Group A versus Group B for parameters ISWT (38.6% vs 42.7%), SGRQ (27.8% vs 21.3%), and HADS total score (20.5% vs 28.1%). These data suggest that benefits of PR in COPD are not age dependent. Age should not be a barrier to enrolling patients with COPD in PR programmes

Detection of a novel RYR1 mutation in four malignant hyperthermia pedigrees

Malignant hyperthermia (MH) is a potentially fatal autosomal dominant disorder of skeletal muscle and is triggered in susceptible people by all commonly used inhalational anaesthetics and depolarizing muscle relaxants. To date, six mutations in the skeletal muscle ryanodine receptor gene (RYR1) have been identified in malignant hyperthermia susceptible (MHS) and central core disease (CCD) cases. Using SSCP analysis, we have screened the RYR1 gene in affected individuals for novel MHS mutations and have identified a G to A transition mutation which results in the replacement of a conserved Gly at position 2433 with an Arg. The Gly2433Arg mutation was present in four of 104 unrelated MHS individuals investigated and was not detected in a normal population sample. This mutation is adjacent to the previously identified Arg2434His mutation reported in a CCD/MH family and indicates that there may be a second region in the RYR1 gene where MHS/CCD mutations cluste

Electrochemical formation of N–substituted polypyrrole nanowires, microwires and open microtubes and their decoration with copper structures

The substituted pyrrole monomer, N–(2–cyanoethyl)pyrrole, was electropolymerised in a 70% water and 30% ethanol solution with ClO4– and H2PO4– as the dopant species to give nanowires at short electropolymerisation times and microwires at longer deposition periods. On adding toluene to the electropolymerisation solution, hollow microtubes were formed. This was attributed to the adsorption of toluene droplets at the electrode surface which served to separate the dopants from the monomer, with the monomer being highly soluble in the toluene droplet and the inorganic dopants soluble in the water/ethanol mixture. As a result electropolymerisation was confined to the toluene-water/ethanol interface. These polymer systems exhibit redox activity with the oxidation wave centred at about 0.40 V vs SCE, and the broader reduction wave positioned between 0.75 V and 0.25 V vs SCE. Although N-substitution reduces the conductivity of the polymer, various copper deposits, including cubes, leaves and hierarchical structures were deposited at the microwires and microtubes using high overpotentials. The hierarchical structures were wrapped around the microtubes at considerable distances, typically 3–4 µm, from the substrate

Factors influencing referral to and uptake and attendance of pulmonary rehabilitation for chronic obstructive pulmonary disease: a qualitative evidence synthesis of the experiences of service users, their families, and healthcare providers (Protocol)

This is a protocol for a Cochrane Review (Qualitative). The object ives are as follows: • To identify factors that influence referral to pulmonary rehab ilitation for COPD from the perspective of service users, thei r family/carers, and healthcare providers. • To identify factors that influence uptake of pulmonary rehabil itation for COPD (i.e. at least one attendance of an assessment or first programme session) from the perspective of service users , their family/carers, and healthcare providers. • To identify factors that influence attendance at pulmonary reha bilitation programmes for COPD from the perspective of servi ce users, their family/carers, and healthcare providers. • To develop an inductive explanatory framework for how these f actors may interact to contribute to better or poorer uptake or completion of pulmonary rehabilitation in order to guide acti ons of healthcare decision-makers to improve opportunities fo r people with COPD to benefit from pulmonary rehabilitation

The definitive version was published in Journal of Geophysical Research 111 (2006): C02006, doi:10.1029/2005JC003011.Net northward transport below γn > 28.1 kgm−3 (≈3200 m) into the Perth Basin of between 4.4 and 5.8 Sv is estimated from a year-long current meter mooring array between the Broken and Naturaliste Plateaus. Northward transport of between 2.0 and 2.5 Sv of Antarctic Bottom Water (γn >28.2 kgm−3), that must upwell within the southern region of the Perth Basin, results in an area-averaged diapycnal velocity and diffusivity of w*=2.5− 3.1× 10−6 ms−1 and κ = 13−15×10−4 m2s−1, respectively. Diffusivity estimates for the Perth Basin are several times larger than area averaged mixing estimates for the abyssal subtropical South Atlantic and Pacific Oceans. However, the dissipation of turbulent kinetic energy required to maintain the abyssal mixing in the Perth basin, ε=O(10−9 Wkg−1), is similar to that required in the South Atlantic Ocean. The area-averaged diffusivity in the Perth Basin does not require unreasonable energy dissipation rates as this ocean basin is only weakly stratified. The abyssal diffuvisity of the Perth Basin results from intense mixing at the basin boundary and in the basin interior over rough topography. The complex bathymetry and low abyssal stratification suggests that the Indian Ocean, for a given energy dissipation, may support a larger meridional overturning circulation than other subtropical basins.BMS was supported by funds from the Ocean and Climate Change Institute at the Woods Hole Oceanographic Institution, and The James S.

Community research report

University College Cork introduced its first Community-based Participatory Research (CBPR) module in 2016. The module was funded and supported by Horizon2020 funding, specifically the EnRRICH project (Enhancing Responsible Research and Innovation through Curricula in Higher Education). The module is a 5-credit module for PhD students from all disciplines in the early stages of their PhD at University College Cork. Following two fruitful partnerships in the areas of social justice / equality, community family support services and older persons, there was a keen interested to explore partnerships in markedly different areas such as environmental sustainability. A dialogue ensued with CEF where the opportunity and feasibility to collaborate on the CBPR module was explored
