Dietary oleic acid is inversely associated with pancreatic cancer – Data from food diaries in a cohort study

Background

Dietary oleic acid may prevent pancreatic ductal adenocarcinoma (PDA) by reducing hyperinsulinaemia which can otherwise promote DNA damage and tumour growth. Results from previous epidemiological studies investigating oleic acid are inconsistent. This study aims to clarify the relationship between dietary oleic acid intake and the risk of developing PDA using nutritional information from food diaries plus published serum biomarker data from HbA1c.

Radiation Dose Benchmarks During Cardiac Catheterization for Congenital Heart Disease in the United States

ObjectivesThe aim of this study was to define age-stratified, procedure-specific benchmark radiation dose levels during interventional catheterization for congenital heart disease.BackgroundThere is a paucity of published literature with regard to radiation dose levels during catheterization for congenital heart disease. Obtaining benchmark radiation data is essential for assessing the impact of quality improvement initiatives for radiation safety.MethodsData were obtained retrospectively from 7 laboratories participating in the Congenital Cardiac Catheterization Project on Outcomes collaborative. Total air kerma, dose area product, and total fluoroscopy time were obtained for the following procedures: 1) patent ductus arteriosus closure; 2) atrial septal defect closure; 3) pulmonary valvuloplasty; 4) aortic valvuloplasty; 5) treatment of coarctation of aorta; and 6) transcatheter pulmonary valve placement.ResultsBetween January 2009 and July 2013, 2,713 cases were identified. Radiation dose benchmarks are presented including median, 75th percentile, and 95th percentile. Radiation doses varied widely between age groups and procedure types. Radiation exposure was lowest in patent ductus arteriosus closure and highest in transcatheter pulmonary valve placement. Total fluoroscopy time was a poor marker of radiation exposure and did not correlate well with total air kerma and dose area product.ConclusionsThis study presents age-stratified radiation dose values for 6 common congenital heart interventional catheterization procedures. Fluoroscopy time alone is not an adequate measure for monitoring radiation exposure. These values will be used as baseline for measuring the effectiveness of future quality improvement activities by the Congenital Cardiac Catheterization Project on Outcomes collaborative.

Extensive Analysis on the Effects of Post-Deposition Annealing for ALD-Deposited Al2O3 on an n-Type Silicon Substrate

In this study, an investigation was performed on the properties of atomic-layer-deposited aluminum oxide (Al₂O₃) on an n-type silicon (n-Si) substrate based on the effect of post-deposition heat treatment, which was speckled according to ambient temperature and treatment applied time. Based on these dealings, a series of distinctions for extracted capacitance and dielectric constant, hysteresis was performed on annealed and nonannealed samples. The interface and border trap responses, including stress behavior after an application of constant voltage for a specific time and surface morphology by X-ray diffraction (XRD) technique, were also analyzed between the two above-mentioned sample types. Based on observation, the annealed samples showed superior performance in every aspect compared with the nonannealed ones. Some unusual behaviors after high annealing temperature were found, and the explanation is the ion diffusion from oxide layer towards the semiconductor. Since a constant voltage stress was not widely used on the metal–oxide–semiconductor capacitor (MOSCAP), this analysis was determined to reveal a new dimension of post-deposition annealing condition for the Al/Al₂O₃/n-Si gate stack.     

Congenital tuberculosis in an extremely preterm infant and prevention of nosocomial infection

Congenital tuberculosis is a rare disease, especially in non-endemic countries. We present a preterm infant who developed congenital tuberculosis in a neonatal intensive care unit (NICU). The male patient, weighing 1140 g was born by cesarean section at 26 weeks gestation. The baby's respiratory condition suddenly deteriorated at 18 days old, and he was diagnosed with congenital tuberculosis after Gram stain revealed “ghost bacilli” in his tracheal aspirate. The mother, who was born in an endemic country, had fever with unknown cause during labor and was diagnosed with miliary tuberculosis after the infant was diagnosed. Both were successfully treated for tuberculosis with a four-drug regimen. The genotyping profiles of Mycobacterium tuberculosis were identical in both mother and baby based on variable number of tandem repeat (VNTR) analysis. The lineage was considered to be East-African Indian. To prevent nosocomial infection in the NICU, 23 potentially exposed infants received isoniazid for 2 months. Two infants showed a transient liver enzyme elevation that seemed to be due to isoniazid. For 10 months after the incident, there were no infants and medical staff who developed tuberculosis. Although the incidence of tuberculosis has steadily decreased in Japan, the percentage of foreign-born individuals has increased yearly, especially those of reproductive age. The evaluation of active tuberculosis should be considered in pregnant women with unexplained fever, history of tuberculosis, or emigration from high-burden areas.     

Aortic stiffness index and its association with cardiovascular functions in children before and after transcatheter closure of PDA

Background

Patent ductus arteriosus is generally associated with hyperdynamic status. Given the vascular shunt between the aorta and pulmonary artery, intrinsic aortic changes occur (aortic stiffness). In the present study, we attempted to assess the impact of PDA on aortic stiffness and its connection with cardiovascular function before and after transcatheter closure of PDA.
