FOMC communications and the predictability of near-term policy decisions
In February 1994, the FOMC began a new era in transparency, gradually building a communications apparatus that conveys information about the Committee’s decisions and expectations. Has the new apparatus improved the public’s ability to predict FOMC interest rate decisions? New research based on the prices of fed funds futures shows that over the past decade, it has, especially over horizons of two to three months.Federal Open Market Committee ; Federal funds rate
Audit of antenatal clinic for high-risk obstetric patients; activity and outcomes
A specialised clinic for the antenatal care of high-risk patients was established in Cork in January 2004. It is led
by 2 specialists in materno-fetal medicine and provides care for patients from a large catchment area. Small clinic
numbers, specialised midwives, ready access to medical experts and fetal assessment facilities, facilitate an
efficient use of resources. We report on the experience and outcomes of this clinic after the first year in operation.
A database was set up to store relevant information on patients who attended the clinic in 2004. 143 patients
attended. Risk categories included maternal medical disease (62%); multiple pregnancy (11%); previous poor obstetric
history (10%); fetal anomaly (8%). Average gestation; 35.9 weeks, average birth weight; 2598g. Caesarean section rate;
41%. Perinatal mortality rate 67 per 1000 (uncorrected); and 20% neonates required NICU care. This approach to
highrisk obstetric care resulted in favourable outcomes. The management strategy applied in Cork may be a suitable
prototype for comparable areas throughout Ireland
The decline of laparoscopic sterilisation
Female sterilisation is an extensively used method of contraception all over the world but there appears to be a decline in the performance of this procedure in Ireland. There also appears to be an increased uptake of safe, long-acting contraceptive alternatives. We set out to establish the extent of the decline of laparoscopic sterilisation and to explore possible explanations. Data for female sterilisation from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2004. Recent sales figures for long acting reversible contraceptives, specifically the levo-norgestrel-loaded intrauterine system (LNG-IUS) (Mirena) and the etonogestrel implant (Implanon) were also obtained. Laparoscopic tubal ligations reduced from 2,566(1999) to 910 (2004). In the corresponding period the use of Mirena coils increased from 4,840 (1999) to 17,077 (2004)
Ascertaining women’s preferred mode of address and preferred choice of title during pregnancy and childbirth
To determine how women in pregnancy would like to be addressed and to ascertain their preferred choice of title during pregnancy. A questionnaire was administered to 925 antenatal women. Midwifery and medical staff (183) were invited to respond to a similar questionnaire.The response rate was 71.2% from the survey of pregnant women. The vast majority (82.1%) preferred to be addressed by their first name. Women were in favour of being called ’patient’ (32.8%) as their first choice. The staff survey yielded a response rate of 77%. The majority (81.8%) of health professionals preferred to address women by their first name. ’Mother’ (28.7%) was the most popular first choice. We conclude that women in pregnancy do have a preference on how they would like to be addressed and this is predominantly by first name. Health professionals also prefer to call pregnant women by their first name. The term ’patient’ was the most popular first choice of title of women in pregnancy but the term ’mother’ was the preferred choice of the health professionals. Medical staff were more likely to choose ’patient’ than midwives
Communication and Group Perception: Extending the `Saying is Believing' Effect
The saying-is-believing (SIB) effect occurs when tailoring a message to suit an audience influences a communicator's subsequent memories and impressions about the communication topic. Previous studies were restricted to one-person audiences and individuals as the communication topic. The present studies explored the SIB effect with multiple-person audiences and groups as the communication topic. In Study 1, the SIB effect occurred with a 1-person, but not a 3-person, audience. In Study 2, the SIB effect occurred with a 3-person audience when the audience explicitly validated communicators' messages. These findings demonstrate the generalizability of the SIB effect to group contexts, provide further evidence for a shared reality interpretation of this effect, and suggest a potentially important mechanism underlying stereotype development
In Vivo Volume and Hemoglobin Dynamics of Human Red Blood Cells
Human red blood cells (RBCs) lose ∼30% of their volume and ∼20% of their hemoglobin (Hb) content during their ∼100-day lifespan in the bloodstream. These observations are well-documented, but the mechanisms for these volume and hemoglobin loss events are not clear. RBCs shed hemoglobin-containing vesicles during their life in the circulation, and this process is thought to dominate the changes in the RBC physical characteristics occurring during maturation. We combine theory with single-cell measurements to investigate the impact of vesiculation on the reduction in volume, Hb mass, and membrane. We show that vesicle shedding alone is sufficient to explain membrane losses but not volume or Hb losses. We use dry mass measurements of human RBCs to validate the models and to propose that additional unknown mechanisms control volume and Hb reduction and are responsible for ∼90% of the observed reduction. RBC population characteristics are used in the clinic to monitor and diagnose a wide range of conditions including malnutrition, inflammation, and cancer. Quantitative characterization of cellular maturation processes may help in the early detection of clinical conditions where maturation patterns are altered
Poor uptake of reproductive health screening services by female renal transplant recipients.
Women with functioning renal transplants are a high-risk group for de novo malignancies and other gynaecological
health problems. The objective of this study was to assess patients awareness of gynaecological issues, and to assess
uptake of cervical and breast cancer screening services. A structured questionnaire on family planning, menopausal
issues and knowledge/use of cervical and breast cancer screening was administered to 64 female renal transplant
recipients. 58 (91%) responded to the questionnaire. Mean age at first transplantation was 35 years (range 11 - 69).
84% were aware as to why they should have regular cervical smears. 15 (26%) had, however, never had a smear and only 9
(16%) were having yearly smears. 12 of 28 postmenopausal women entered the menopause under the age of 41 years, but
only 5 of these had received Hormone Replacement Therapy. Breast self examination is practiced by 71%, but only 26%
have had mammograms. These figures suggest that female renal transplant patients are not adequately screened for
cervical and breast cancer. The results also indicate a need for further education regarding family planning issues
and menopausal health concerns. We conclude that formal gynaecological review should be routinely available for women with renal transplants

Using genomic DNA-based probe-selection to improve the sensitivity of high-density oligonucleotide arrays when applied to heterologous species
High-density oligonucleotide (oligo) arrays are a powerful tool for transcript profiling. Arrays based on GeneChip® technology are amongst the most widely used, although GeneChip® arrays are currently available for only a small number of plant and animal species. Thus, we have developed a method to improve the sensitivity of high-density oligonucleotide arrays when applied to heterologous species and tested the method by analysing the transcriptome of Brassica oleracea L., a species for which no GeneChip® array is available, using a GeneChip® array designed for Arabidopsis thaliana (L.) Heynh. Genomic DNA from B. oleracea was labelled and hybridised to the ATH1-121501 GeneChip® array. Arabidopsis thaliana probe-pairs that hybridised to the B. oleracea genomic DNA on the basis of the perfect-match (PM) probe signal were then selected for subsequent B. oleracea transcriptome analysis using a .cel file parser script to generate probe mask files. The transcriptional response of B. oleracea to a mineral nutrient (phosphorus; P) stress was quantified using probe mask files generated for a wide range of gDNA hybridisation intensity thresholds. An example probe mask file generated with a gDNA hybridisation intensity threshold of 400 removed > 68 % of the available PM probes from the analysis but retained >96 % of available A. thaliana probe-sets. Ninety-nine of these genes were then identified as significantly regulated under P stress in B. oleracea, including the homologues of P stress responsive genes in A. thaliana. Increasing the gDNA hybridisation intensity thresholds up to 500 for probe-selection increased the sensitivity of the GeneChip® array to detect regulation of gene expression in B. oleracea under P stress by up to 13-fold. Our open-source software to create probe mask files is freely available http://affymetrix.arabidopsis.info/xspecies/ webcite and may be used to facilitate transcriptomic analyses of a wide range of plant and animal species in the absence of custom arrays
A possible relation between dietary zinc and cAMP in the regulation of tumour cell proliferation in the rat
The possibility of an effect of zinc on the rate of tumour cell division, mediated through a regulation of cellular cAMP concentration, was investigated in the present study in rats. Dietary Zn deficiency (< 1·5 mg Zn/kg) but not Zn excess (500 mg Zn/kg) resulted in an increased cAMP concentration in transplanted hepatoma cells. Neither treatment had any effect on the cAMP concentration in regenerating liver or normal resting liver. Both the deficient and excess Zn diets resulted in a small reduction in tumour growth (not statistically significant). The results seem to indicate that the relation investigated in the present study does not apply in the cell line used
