Time to ECG diagnosis delays inter-hospital transfer to revascularization in STEMI patients presenting to a regional emergency department: a five-year audit.

Background: Reducing the door-to-balloon time (D2BT) in ST-elevation myocardial infarction (STEMI) patients maximizes myocardial salvage and mitigates morbidity/mortality.

Aims: To assess the D2BT in STEMI patients requiring inter-hospital transfer for revascularization and identify any potential causes of delay.

Methods: Consecutive patients presenting to the Connolly Hospital Blanchardstown (CHB) emergency department (ED) who were transferred to the Mater Misericordiae University Hospital in Dublin for primary percutaneous coronary intervention from January 2018 to October 2022 were identified in a regional database and their D2BTs calculated.

Electrocardiographic predictors of response to sacubitril/valsartan therapy in heart failure with reduced ejection fraction.

Background: Sacubitril/valsartan (SV) is currently recommended as a first-line therapy in patients with heart failure and reduced ejection fraction (HFrEF) due to its significant clinical and prognostic benefit; however, not all patients respond to therapy and predictors of clinical response to SV remain under-studied.

Aims: To identify electrocardiographic (ECG) predictors of response to SV therapy in HFrEF patients.

Methods: A retrospective analysis of a hospital heart failure registry was undertaken.

Fractional Flow Reserve-Guided Stent Optimisation in Focal and Diffuse Coronary Artery Disease.

Assessing coronary physiology after stent implantation facilitates the optimisation of percutaneous coronary intervention (PCI). Coronary artery disease (CAD) patterns can be characterised by the pullback pressure gradient (PPG) index. The impact of focal vs.

Angina After Percutaneous Coronary Intervention: Patient and Procedural Predictors.

Background: Twenty percent to 40% of patients are affected by angina after percutaneous coronary intervention (PCI), which is associated with anxiety, depression, impaired physical function, and reduced quality of life. Understanding patient and procedural factors associated with post-PCI angina may inform alternative approaches to treatment.

Methods: Two hundred thirty patients undergoing PCI completed the Seattle Angina Questionnaire (SAQ-7) and European quality of life-5 dimension-5 level (EQ-5D-5L) questionnaires at baseline and 3 months post-PCI.

Modelling the outcomes of different red blood cell transfusion strategies for the treatment of traumatic haemorrhage in the prehospital setting in the United Kingdom.

Background And Objectives: The limited supply and increasing demand of group O RhD-negative red blood cells (RBCs) have resulted in other transfusion strategies being explored by blood services that carry potential risks but may still provide an overall benefit to patients. Our aim was to analyse the potential economic benefits of prehospital transfusion (PHT) against no PHT.

Materials And Methods: The impact of three PHT strategies (RhD-negative RBC, RhD-positive RBC and no transfusion) on quality-adjusted-life-years (QALYs) of all United Kingdom trauma patients in a given year and the subset of patients considered most at risk (RhD-negative females <50 years old), was modelled.

Immunoproteomic analysis of the secretome of bovine-adapted strains of Staphylococcus aureus demonstrates a strain-specific humoral response.

Staphylococcus aureus is a common pathogen associated with bovine intramammary infection. A number of distinct S. aureus lineages are associated with such infections although there is a dearth of knowledge regarding the major immunogenic antigens associated with each lineage and whether these antigens provide protection against heterologous strains.

Label-free quantitative proteomic analysis of M. longissimus dorsi from cattle during dietary restriction and subsequent compensatory growth.

Compensatory growth (CG) is a naturally occurring physiological process whereby an animal has the ability to undergo enhanced growth following a period of restricted feeding. This studies objective was to identify key proteins involved in the expression of CG. Forty Holstein Friesian bulls were equally assigned to one of four groups.

'Acute micro-coronary syndrome': detailed coronary physiology in a patient with Takotsubo cardiomyopathy.

Takotsubo cardiomyopathy (TC), otherwise known as stress cardiomyopathy, is characterised by acute, transient left ventricular systolic dysfunction with apical ballooning in the absence of obstructive epicardial coronary stenosis. The presentation of TC mimics that of acute myocardial infarction. More recently there has been a shift towards thinking of TC as a 'microvascular acute coronary syndrome'.

Impact of a telephone-first consultation system in general practice.

Purpose Of The Study: Increasing pressure on general practice prompts innovative change in service organisation. This study sought to evaluate the impact of introducing a telephone-first consultation system in a socioeconomically deprived population.

Study Design: An interrupted time series of preplanned outcomes for 2 years before and 1 year postintroduction of a telephone-first system was used to measure the volume and type of general practitioner (GP) consultations and the number of patients consulted per year.

Sex in Marriage: Love-Giving, Live-Giving.

In 1969, Cardinal O'Boyle addressed many questions people had about the teachings of Pope Paul VI's encyclical . Topics covered then are still of interest today to new generations: questions on revelation, conscience, infallibility, contraception, natural family planning, religious assent, government involvement in birth control, faith, morality, natural law, the ends of marriage, the spirit of Vatican II, receiving the sacraments, overpopulation, responsible parenthood, and disagreement among theologians, among others. Cardinal O'Boyle's answers are as enlightening and relevant today as they were then.

The miRNAome of the postpartum dairy cow liver in negative energy balance.

Background: Negative energy balance (NEB) is an altered metabolic state in high yielding cows that occurs during the first few weeks postpartum when energy demands for lactation and maintenance exceed the energy supply from dietary intake. NEB can, in turn, lead to metabolic disorders and to reduced fertility. Alterations in the expression of more than 700 hepatic genes have previously been reported in a study of NEB in postpartum dairy cows.

Alterations in hepatic miRNA expression during negative energy balance in postpartum dairy cattle.

Background: Negative energy balance (NEB), an altered metabolic state, occurs in early postpartum dairy cattle when energy demands to support lactation exceed energy intake. During NEB the liver undergoes oxidative stress and increased breakdown of fatty acids accompanied by changes in gene expression. It is now known that micro RNAs (miRNA) can have a role in mediating such alterations in gene expression through repression or degradation of target mRNAs.

Composition of the bovine uterine proteome is associated with stage of cycle and concentration of systemic progesterone.

Early embryonic loss accounts for over 70% of total embryonic and foetal loss in dairy cattle. Early embryonic development and survival is associated with the concentration of systemic progesterone. To determine if the uterine proteome is influenced by stage of cycle or systemic progesterone concentrations, uterine flushings were collected from the ipsi- and contralateral uterine horns of beef heifers on Days 7 (n = 10) and 15 (n = 10) of the oestrous cycle.

Insulin-like growth factor and insulin-like growth factor-binding proteins in the bovine uterus throughout the oestrous cycle.

The aims of the present study were to assess several components of the insulin-like growth factor (IGF) system in bovine uterine flushings across different days of the oestrous cycle and to examine the relationship between the IGF system and systemic progesterone concentrations. Uterine flushings and plasma were collected from cows on Days 3, 7, 11 and 15 of the oestrous cycle. The IGF-1 concentration was more than 5-fold higher in the uterus compared with plasma on Days 7 and 11 of the cycle, with values similar on Days 3 and 15.

A comparison of the bovine uterine and plasma proteome using iTRAQ proteomics.

Early embryo loss is a key factor affecting fertility in dairy and beef herds. Prior to implantation, the bovine embryo spends around 16 days free-floating in the uterine environment and is dependent on the composition of uterine fluid for normal growth and development. However, there is a lack of information regarding the protein composition of the bovine uterus and how it relates to plasma.

Single nucleotide polymorphisms in the growth hormone and insulin-like growth factor-1 genes are associated with milk production, body condition score and fertility traits in dairy cows.

The somatotrophic axis (GH-IGF) is a key regulator of animal growth and development, affecting performance traits that include milk production, growth rate, body composition, and fertility. The aim of this study was to quantify the association of previously identified SNPs in bovine growth hormone (GH1) and insulin-like growth factor 1 (IGF-1) genes with direct performance trait measurements of lactation and fertility in Holstein-Friesian lactating dairy cows. Sixteen SNPs in both IGF-1 and GH1 were genotyped across 610 cows and association analyses were carried out with traits of economic importance including calving interval, pregnancy rate to first service and 305-day milk production, using animal linear mixed models accounting for additive genetic effects.

Immunodepletion of albumin and immunoglobulin G from bovine plasma.

Current MS-based proteomics has facilitated the identification of large numbers of proteins from complex mixtures. The bovine plasma proteome has the potential to provide a wealth of information concerning the biological state of an animal. However, during MS-based experiments, higher abundance proteins such as albumin and immunoglobulin G (IgG) can hinder the identification of potentially important proteins that are present in much lower abundance.

Genetic Characterization of Barley Net Blotch Resistance Genes.

Net blotch, caused by Pyrenophora teres f. teres, is one of the most devastating diseases of barley (Hordeum vulgare). Efficient utilization of available resistance sources is dependent upon successful characterization of genes conditioning resistance in diverse sources.

Retinol-binding protein (RBP), retinol and β-carotene in the bovine uterus and plasma during the oestrous cycle and the relationship between systemic progesterone and RBP on day 7.

In the dairy cow, low systemic concentrations of progesterone are known to be a major factor associated with early embryo loss. Endometrial expression of the gene encoding retinol-binding protein (RBP) is sensitive to small changes in progesterone on day 7 of the oestrous cycle. The objectives of the present study were to measure RBP concentrations in bovine uterine flushings and plasma across different days of the oestrous cycle and to examine the relationship between uterine RBP and systemic concentrations of progesterone.

De novo HLA sensitization and antibody mediated rejection following pregnancy in a heart transplant recipient.

Here we report a case wherein both donor-specific and third-party, paternal, HLA class II specific antibodies developed following a spontaneous miscarriage resulting in antibody-mediated rejection in a patient who had undergone an orthotopic cardiac transplant six years earlier.

Effect of level and duration of dietary n-3 polyunsaturated fatty acid supplementation on the transcriptional regulation of Delta9-desaturase in muscle of beef cattle.

The objective of this study was to examine the effect of level and duration of feeding of an n-3 PUFA-enriched fish oil (FO) supplement in combination with soybean oil (SO) on the transcriptional regulation of Delta(9)-desaturase gene expression in bovine muscle. Beef bulls (n = 40) were assigned to 1 of 4 iso-lipid and isonitrogenous concentrate diets fed for ad libitum intake for a 100-d finishing period. Concentrates were supplemented with one of the following: 1) 6% SO (CON); 2) 6% SO + 1% FO (FO1); 3) 6% SO + 2% FO (FO2); or 4) 8% palmitic acid for the first 50 d and 6% SO + 2% FO for the second 50 d [FO2(50)].

Underutilization of echocardiography for patent foramen ovale in divers with serious decompression sickness.

The presence of a patent foramen ovale (PFO) in compressed gas diving has been considered a risk factor for serious decompression illness (DCS) for more than 20 years. We conducted a ten year retrospective chart review aimed at determining if physicians treating DCS in a university medical center setting used echocardiography to assess PFO in patients with severe DCS, and if so whether PFO is over-represented in that population. Over the ten-year period, 113 divers underwent recompression therapy for decompression sickness.
