Abstract
BACKGROUND Approximately 1 billion people worldwide have Vitamin D deficiency. The aim of this study was to compare Vitamin D status and serum 25-hydroxyvitamin D (25(OH)D) concentrations among adults sampled in the community, in outpatient clinics, as hospital inpatients and in nursing homes in the West of Ireland. The secondary aim was to determine the associations between length of hospital stay (inpatients) at the time of serum 25(OH)D sampling and Vitamin D status. METHODS A cross-sectional study was carried out. Patients who had serum 25(OH)D analysis carried out in Galway University Hospitals (January 2011-December 2015) were identified following interrogation of the electronic laboratory data system. Baseline demographics, location, and date of sample collection were recorded. Vitamin D deficiency was defined as a serum 25(OH)D concentration <25 nmol/L. RESULTS In total, 24,302 patient samples were eligible for inclusion: community 15,319; outpatient clinics 6,371; inpatients 2,339; and nursing home residents 273. Vitamin D deficiency was more common in nursing home residents than inpatients, or those sampled in outpatient clinics or in the community (42% vs 37% vs 17% vs 13%; p < .001). Inpatients sampled further into their hospital stay (≥3 days) had greater Vitamin D deficiency than inpatients sampled on 0-2 days (p = .007). Season (p < .001), sex (p < .001), and age (p < .001) were associated with 25(OH)D concentrations. Vitamin D deficiency was more common in Winter/Spring, in males, and in those aged ≥80 years. CONCLUSIONS Nursing home residents and inpatients are at the highest risk for Vitamin D deficiency. Season, sex, age, and day of hospital stay on which serum 25(OH)D concentrations were sampled were associated with Vitamin D status.

Abstract
BACKGROUND AND AIMS There is limited information on reference values for lipids and lipoproteins in an Irish population. In this observational study, we have described the distributions of lipids in a large Irish cohort. METHODS Over 110,000 lipid profiles were selected from a database of almost 1.5 million consecutive lipid profiles performed in the Clinical Biochemistry Laboratory in University Hospital Galway between 2004 and 2017 to best represent the Irish population. Age- and sex-related reference intervals for both sexes for total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, from the age of ten to greater than 90 years, were determined. Two methods for estimating LDL cholesterol were also compared. RESULTS Sex-related differences in lipid distributions arise before the age of 20 years and are life-long. In both sexes total and LDL cholesterol levels gradually increased towards middle age with a decrease towards old age. Levels tended to be higher in males than in females up to mid-life at which stage they cross over with females having on average higher levels. The median of the triglyceride distributions show similar age- and sex-related changes to total cholesterol, but the distributions show a very marked positive skew that is particularly obvious in middle aged males. HDL cholesterol distributions change little throughout life with males having lower levels than females. Changing from the Friedewald formula to that proposed by Martin would impact the management of some patients with dyslipidaemia. CONCLUSIONS This study provides lipid reference values for clinical biochemistry laboratories and clinicians working in Ireland. It is informative for public health initiatives wishing to target dyslipidaemia as a modifiable risk for cardiovascular disease and for investigators researching geographical and temporal variances in lipid parameters.

Abstract
Introduction Coronavirus disease 2019 (COVID-19), is a respiratory illness caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The Clinical Blood Sciences Laboratory (CBSL) plays a key role in supporting the monitoring and management of patients with COVID-19 disease. Objective To provide a comprehensive CBSL testing protocol to support the medical management of SARS-CoV-2 infection. Methods Description of the biochemical, haematological and immunological tests that have a role in the assessment and monitoring of patients with COVID-19 infection. Results We provide a test menu for clinical laboratories to ensure the effective monitoring, management and prognostication of COVID-19 patients in hospital. Conclusion Given the rapidity with which patients with COVID-19 disease can deteriorate, we recommend regular testing with vigilance paid to the rate and trajectory of change in each of these parameters.

Abstract
Recent studies suggest a possible association between dephosphorylated-uncarboxylated MGP (dp-ucMGP) and glomerular filtration rate (GFR). This study aimed to establish normative data in an adult Caucasian population and to explore the potential utility of dp-ucMGP in patients with diabetes mellitus (DM) with and without diabetic kidney disease (DKD). Healthy volunteers (HVs) (cross-sectional study) and participants with DM (prospective cohort study) were recruited. Plasma dp-ucMGP was measured using the IDS®-iSYS Ina Ktif (dp-ucMGP) assay. Of the HVs recruited (n = 208), 67(32.2%) were excluded leaving a reference population of 141(67.8%) metabolically healthy participants with normal kidney function. Plasma dp-ucMGP RIs were <300-532 pmol/L. There were 100 eligible participants with DKD and 92 with DM without DKD. For the identification of participants with DKD, the area under the receiver operating characteristic curve (AUC) for dp-ucMGP was 0.842 (95%CI:0.799-0.880; p < 0.001). Plasma dp-ucMGP demonstrated similar ability to urine albumin:creatinine ratio (uACR) to detect participants with DM and renal function decline. Among patients with DM, there was a negative correlation between natural log (LN) dp-ucMGP and eGFR (r = -0.7041; p < 0.001) and rate of change in renal function [%change (r = -0.4509; p < 0.001)] and a positive correlation between LN dp-ucMGP and LN uACR (r = 0.3392; p < 0.001). These results suggest the potential for plasma dp-ucMGP with well-defined RIs to identify adults at high risk for vascular disease in the context of progressive DKD.

Abstract
PURPOSE Investigate circulating CCL5 in breast cancer patients and healthy controls, along with gene expression levels in corresponding tumour tissue and isolated primary stromal cells. Hormonal control of CCL5, and a potential relationship with TGFβ1, was also investigated. METHODS Circulating levels of CCL5 and TGFβ1 were measured in 102 breast cancer patients and 66 controls using ELISA. Gene expression levels (CCL5, CCR5, TGFβ1, TGFβRII) were quantified in corresponding tumour tissue (n = 43), normal tissue (n = 16), and isolated tumour (n = 22) and normal (n = 3) stromal cells using RQ-PCR. CCL5 and circulating menstrual hormones (LH, FSH, Oestradiol, Progesterone) were analysed in serum samples from healthy, premenopausal volunteers (n = 60). RESULTS TGFβ1 was significantly higher in breast cancer patients (Mean(SEM) 27.4(0.9)ng/ml) compared to controls (14.9(0.9)ng/ml). CCL5 levels decreased in the transition from node negative (59.6(3.7)ng/ml) to node positive disease (40.5(6.3)ng/ml) and increased again as the number of positive lymph nodes increased (⩾3 positive 50.95(9.8)ng/ml). A significant positive correlation between circulating CCL5 and TGFβ1 (r = 0.423, p<0.0001) was observed, and mirrored at the gene expression level in tumour tissue from the same patients (r = 0.44, p<0.001). CCL5, CCR5 and TGFβ1 expression was significantly higher in tumour compared to normal breast tissue (p < 0.001). A significant negative correlation was observed between circulating CCL5, Oestradiol and Progesterone (r = -0.50, r = -0.39, respectively, p < 0.05). CONCLUSION CCL5 expression is elevated in the tumour microenvironment. The data support a role for hormonal control of circulating CCL5 and also highlight a potentially important relationship between CCL5 and TGFβ1 in breast cancer.

Abstract
Familial aggregations of nephrolithiasis were already noted in the early 19th century and over the intervening years there has been gradual progression in classifying the familial forms of nephrolithiasis. To date, there are at least 10 different monogenic conditions where those affected have a predisposition to nephrolithiasis. However, all of these rare conditions probably account for less than 2% of renal stone formers. This review, rather than considering these clearly defined disorders, concentrates on research into the broad band of stone formers who have a propensity to nephrolithiasis without an obvious discrete genetic basis.

Abstract
Charcoal and sodium nitrate, the active ingredients in pesticide gas cartridges, are quantified via carbon analysis and ion chromatography, respectively. Linearity was excellent (R(2) > 0.995) over a range consisting of 50-150% of the target concentration for both ingredients. The coefficient of variation for the replicate analyses of gas cartridges over multiple days was <4% for both analytes. Using the results from the analysis of two batches of gas cartridges, theoretical populations were modeled and used to determine practical sampling strategies to support a quality control program for a gas cartridge manufacturing operation. This modeling indicates that the analysis of three cartridges from each of five different lots would produce mean values for both active ingredients that are within 5% of the true mean >99% of the time.

Abstract
A cluster of four cases of symptomatic B virus infection in humans occurred in Pensacola, Florida, in March 1987. Three cases occurred in persons who worked with monkeys at a research facility, and the fourth resulted from apparent autoinoculation through use of a nonprescription skin cream. Contact tracing identified 159 persons who may have been exposed to B virus (21 had been exposed to monkeys at the facility and 138 had been exposed to one or more of the case-patients), but no further cases were identified. Comparisons of restriction endonuclease patterns from B virus isolates linked two of the three cases in monkey handlers to one clinically ill monkey and the other to a second, healthy monkey. Three risk factors for human infection were identified: nonuse of mechanical or chemical restraints for monkeys before handling, nonuse of available protective gear, and direct viral inoculation through the application of a topical medication.
