REVIEW
Gregory G Bond, Daniel R Dietrich
Recently published papers have alleged that exposures to endocrine disrupting chemicals (EDCs) are causing substantial disease burdens in the EU and US and are consequently costing society hundreds of billions of dollars annually. To date, these cost estimates have not undergone adequate scientific scrutiny, but nevertheless are being used aggressively in advocacy campaigns in an attempt to fundamentally change how chemicals are tested, evaluated and regulated. Consequently, we critically evaluated the underlying methodology and assumptions employed by the chief architects of the disease burden cost estimates...

Francesco Borromini, one of the great geniuses of Baroque architecture, was tormented and solitary, and was increasingly frustrated by the fame and success of his rival, Gian Lorenzo Bernini. Borromini was an unhappy man, constantly dogged by disaster, quarrelling even with his best patrons and closest friends. In the culmination of one of the fits of depression that overcame the architect more and more frequently as his life progressed, Borromini literally fell on his own sword; he lingered in excruciating pain for 24 hours before dying...

BACKGROUND: Despite the high specificity of fourth-generation enzyme immunoassays (4th-gen-EIA) for screening during HIV diagnosis, their positive predictive value is low in populations with low HIV prevalence. Thus, screening should be optimized to reduce false positive results. OBJECTIVES: The influence of sample cutoff (S/CO) values by a 4th-gen-EIA with the false positive rate during the routine HIV diagnosis in a low HIV prevalence population was evaluated...

The best management of vitamin D deficiency, defined as a 25-hydroxyvitamin D [(25(OH)D] level <50 nM, is unclear. Intramuscular (IM) injection of a large bolus of vitamin D (≥100 000 IU) is used, but its safety is uncertain. In 10 adults given an IM injection of 600 000IU vitamin D₃, we measured at baseline and at 1, 2, 3, and 4 weeks postinjection the serum levels of vitamin D₃, 25(OH)D₃, 25(OH)D₂, total 25(OH)D, 3-epi-25(OH)D₃, and 24,25-dihydroxyvitamin D₃ [24,25(OH)₂D₃] using a standardized LC with tandem MS (MS/MS) assay; serum levels of 25(OH)D using the Abbott ARCHITECT i2000 immunoassay; and markers of bone metabolism...

Screening of blood for human T-cell lymphotropic virus type I and type II (HTLV-I/II) is important to diagnose and prevent infection and ensure the safety of blood supplies. The Elecsys® HTLV-I/II assay is a newly developed, electrochemiluminescence screening assay for the detection of HTLV-I/II infection. The sensitivity and specificity of the Elecsys® HTLV-I/II assay were determined using well-characterized HTLV-I/II-positive serum and plasma samples, and routine diagnostic and blood donor samples expected to be HTLV-negative, respectively...

Over the last years, the omnipresent standardization of playgrounds-the distances between, for example, jumping stones tend to be equal-has been criticized by both scientists and architects. First, it has been argued that standardization fails to do justice to the variability in the children's action capabilities. Second, it might simplify play in that children repetitively cross over the same distance and, thus, do not have to worry about their movements anymore. In the present study we examined the gap-crossing behavior of children in both a standardized and a nonstandardized jumping stone configuration...

Although grazers have long been recognized as top-down architects of plant communities, animal roles in determining microbial community composition have seldom been examined, particularly in aboveground systems. To determine the extent to which an animal can shape microbial communities, we conducted a controlled mesocosm study in situ to see if introducing mycophageous tree snails changed phyllosphere fungal community composition relative to matched control mesocosms. Fungal community composition and change was determined by Illumina sequencing of DNA collected from leaf surfaces before snails were introduced, daily for 3 days and weekly for 6 weeks thereafter...

There is evidence to show an association between inflammation, obesity and elevated blood pressure. However, there is limited data for this relationship in adolescent females. We aimed to investigate the association between high sensitivity C-reactive protein (hs-CRP) and elevated blood pressure in young Australian females. Women aged 16-25 years living in Victoria were randomly recruited via targeted Facebook advertising. Socio-demographic information was collected via a web-based questionnaire. Anthropometric and blood pressure measurements were conducted by trained staff...

BACKGROUND: Transferrin saturation reference intervals specific for age and sex have not been previously reported for the pediatric population. The reference values for transferrin saturation have been previously reported to be lower in children compared to adults, caused by a combination of low serum iron and high serum transferrin levels in children, warranting specific reference intervals. Here we use the original iron and transferrin data from the CALIPER cohort to establish age- and sex-specific pediatric reference intervals for transferrin saturation...

Several reports over the last 10 years provided evidence that long noncoding RNAs (lncRNAs) are often altered in bladder cancers. lncRNAs are longer than 200 nucleotides and function as important regulators of gene expression, interacting with the major pathways of cell growth, proliferation, differentiation, and survival. A large number of lncRNAs has oncogenic function and is more expressed in tumor compared with normal tissues. Their overexpression may be associated with tumor formation, progression, and metastasis in a variety of tumors including bladder cancer...

OBJECTIVE: This review of empirical literature focuses on the design of operating rooms (ORs) by investigating the physical environmental features of ORs associated with patient and staff outcomes. BACKGROUND: Many ORs built more than 30 years ago remain operational today. However, most are inadequately designed to handle the equipment, processes, and people that a contemporary OR needs to accommodate. However, the evidence base for designing ORs has been sorely lacking, and little guidance exists on how OR design can improve safety and performance outcomes...
