BACKGROUND The methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism is a risk factor for neural tube defects. The T allele produces an enzyme with reduced folate-processing capacity, which has been associated with lower blood folate concentrations. OBJECTIVE We assessed the association between MTHFR C677T genotypes and blood folate concentrations among healthy women aged 12-49 y. ...

BACKGROUND UK estimates of age related macular degeneration (AMD) occurrence vary. AIMS To estimate prevalence, number and incidence of AMD by type in the UK population aged ≥50 years. METHODS Age-specific prevalence rates of AMD obtained from a Bayesian meta-analysis of AMD prevalence were applied to UK 2007-2009 population data. Incidence was estimated from modelled age-specific prevalenc...

OBJECTIVES (1)To assess the nutritional status of chronic renal insufficiency (CRI) and dialysis patients using the subjective global assessment (SGA) method. (2) To validate SGA in assessing the nutritional status of this group of patients. PARTICIPANTS The nutritional status of 81 patients was evaluated using dietary recall, anthropometry, biochemical parameters and SGA. There were 51 males...

The role of the Australian Nurse Practitioner (NP) is in its infancy and at a crossroads where extensive research demonstrates effective quality care and yet the role remains underrecognised and underutilised. The translation of practice into "value" is critical for the sustainability of NP roles and requires the practitioner to adopt a systematic method of inquiry. Kim's (1999) "Critical Refle...

Compensatory reserve was measured in baboons (n = 13) during hemorrhage (Hem) and lower-body negative pressure (LBNP) using a machine-learning algorithm developed to estimate compensatory reserve by detecting reductions in central blood volume during LBNP. The algorithm calculates compensatory reserve index (CRI) from normovolemia (CRI = 1) to cardiovascular decompensation (CRI = 0). The hypoth...

Evaluation of tests for the diagnosis of childhood pulmonary tuberculosis (CPTB) is complicated by the absence of an accurate reference test. We present a Bayesian latent class analysis in which we evaluated the accuracy of 5 diagnostic tests for CPTB. We used data from a study of 749 hospitalized South African children suspected to have CPTB from 2009 to 2014. The following tests were used: my...

BACKGROUND Femoral nerve blockade (FNB) is a common method of analgesia for postoperative pain control after total knee arthroplasty. We conducted a systematic review to compare the analgesia outcomes in randomized controlled trials that compared FNB (with and without sciatic nerve block) with epidural and patient-controlled analgesia (PCA). METHODS We identified 23 randomized controlled tria...

Combination of real and imaginary parts (CRI) works well for solving complex symmetric linear systems. This paper develops a generalization CRI method to determine the solution Sylvester matrix equation. We show that this, regardless condition, converges At end we test new scheme by numerical example.

When A/J mice are immunized to p-azobenzenearsonate (ABA) 1 coupled to a protein, such as keyhole limpet hemocyanin (KLH), 20-70% of the anti-ABA antibodies produced bear a common idiotype, known as the cross-reactive idiotype (CRI; 1, 2). CRI is absent in the serum of A/J mice immune to antigens other than ABA. In many other mouse strains, immunization with ABA-KLH results in high levels of an...
