OBJECTIVE: Sleep is viewed as being relatively consistent across the school-age period (6-13 years of age), however this claim has not been empirically supported. The objective of this study was to document the duration, schedule, variability, and week versus weekend discrepancies of sleep in three distinct age groups within the school-age period. METHODS: Participants were divided by age: Cycle 1, 6 and 7 years; Cycle 2, 8 and 9 years; and Cycle 3, 10 and 11 years...

Using hybrid packing materials in biofiltration systems takes advantage of both the inorganic and organic properties offered by the medium including structural stability and a source of available nutrients, respectively. In this study, hybrid mixtures of compost with either lava rock or biochar in four different mixture ratios were compared against 100% compost in a methane biofilter with active aeration at two ports along the height of the biofilter. Biochar outperformed lava rock as a packing material by providing the added benefit of participating in sorption reactions with CH4 ...

BACKGROUND: Carbapenem-resistant Gram-negative bacteria (CRGNB) infections constitute a global threat for critically ill patients and the outcome of their hospitalization. Early identification of CRGNB through rectal surveillance cultures and routine infection control measures including contact precautions, use of appropriate disinfectants, staff education on cleaning, and hand hygiene may reduce the dissemination of CRGNB. AIM: To assess the impact of enhanced infection control measures on CRGNB infections in a nine-bed polyvalent intensive care unit in a tertiary level hospital in an endemic area...

INTRODUCTION: Corrosion casts (CCs) are used for the visualization and assessment of hollow structures. CCs with filled capillaries enable (with the help of imaging methods) to obtain data for mathematical organ perfusion modelling. As the processing is more difficult in case of organs with greater volume of the vasculature, mainly organs from small animals have been cast up to now. The aim of this study was to optimize the protocol of corrosion casting of different organs of pig. Porcine organs are relatively easily accessible and frequently used in experimental medicine...

Pulmonary hypertension is defined as a mean pulmonary arterial pressure ≥25 mmHg. We focus on its relevance in congenital heart disease, reviewing pathophysiology, diagnosis and management. Pulmonary hypertension is a relatively common complication of congenital heart disease, with adult prevalence between 5 and 10%. A multifactorial cause is recognized, relating to the size and nature of cardiac defect as well as environmental and genetic factors. More complex disease is increasingly recognized rather than pure Eisenmenger complex...

BACKGROUND: A stepped care approach involves patients first receiving low-intensity treatment followed by higher intensity treatment. This two-step randomized controlled trial investigated the efficacy of a sequential stepped care approach for the psychological treatment of binge-eating disorder (BED). METHODS: In the first step, all participants with BED (n = 135) received unguided self-help (USH) based on a cognitive-behavioral therapy model. In the second step, participants who remained in the trial were randomized either to 16 weeks of group psychodynamic-interpersonal psychotherapy (GPIP) (n = 39) or to a no-treatment control condition (n = 46)...

We present a unique case of a 62-year-old patient with bilateral osteonecrosis of the femoral heads secondary to corticosteroid use. She presented with an occult right femoral neck fracture and was treated with percutaneous pinning of the right femoral neck and a left-sided percutaneous drilling. Despite apparent appropriate technique, the patient sustained a left sub-trochanteric hip fracture while shifting in bed in the postoperative care unit and was taken back for cephalo-medullary nail fixation. Femoral head osteonecrosis may be an under-reported risk factor for development of pathological neck fractures...

A novel Hybrid Correlation Energy (HyCE) approach is proposed that determines the total correlation energy via distinct computation of its internal and external components. This approach evolved from two related studies. First, rigorous assessment of the accuracies and size extensivities of a number of electron correlation methods, that include perturbation theory (PT2), coupled-cluster (CC), configuration interaction (CI) and coupled electron pair approximation (CEPA), shows that the CEPA(0) variant of the latter and triples-corrected CC methods consistently perform very similarly...

With international demand for production systems aimed at thermal comfort and animal welfare, milk producers have become increasingly interested in compost barns. However, doubts about the behavioral aspects of cows in tropical and subtropical climates remain, because the compost barn system offers a larger bed area per animal at a lower stocking rate. The objective of this study was to evaluate whether the diurnal behaviors, hygiene and lameness of crossbred dairy cows are influenced by different number of lactations when housed in a compost-bedded pack barn system under hot and humid conditions...

Bed bugs are one the most troublesome household pests that feed primarily on human blood. RNA interference (RNAi) is currently being pursued as a potential tool for insect population management and has shown efficacy against some phytophagous insects. We evaluated the different techniques to deliver dsRNA specific to bed bug muscle actin (dsactin) into bed bugs. Initially, stability of dsRNA in human blood was studied to evaluate the feasibility of feeding method. Adult bed bugs were injected with dsRNA between last thoracic segment and first abdominal segment on the ventral side, with a dose of 0...

Porphyromonas gingivalis (Pg), is an important periodontal pathogen that is also implicated in pregnancy complications involving defective deep placentation (DDP). We hypothesized that Pg invasion of the placental bed promotes DDP. Pregnant rats were intravenously inoculated with sterile vehicle, Pg strain W83, or A7436 at gestation day (GD) 14 (acute cohort). Non-pregnant rats received repeated oral inoculations for 3 months before breeding (chronic cohort). Tissues and/or sera were collected at GD18 for analysis...

Jon Erik Finnvold, Elisabeth Ugreninov
Some recent European research claims that immigrants settle in urban areas with low scores on level-of-living conditions and a high prevalence of health-risk factors, and that these settlement patterns adversely affect their health. Other studies question the association between immigrant segregation and area deprivation on one hand, and negative health outcomes on the other hand, and identify possible beneficial effects of segregation, specifically the ethnic density effect. This paper aims to explore the possible ethnic density effect among refugees, a sub-population that often appears relatively vulnerable compared with immigrants in general...

This work studied the optimal conditions for pyrolysis of Prosopis juliflora wood in fixed-bed tubular reactor. The optimal conditions are measured by performing pyrolysis experiment with respect to wood properties such as particle size, moisture and pyrolysis condition such as, temperatures, heating rates. Higher solid yield (36.8%) was recorded for a slower heating rate of larger particle size at lower temperatures. Further, higher liquid yield (38.3%) was observed while maintaining high heating rate and temperature...

In conventional gating approaches for PET, a single number of gates is predetermined for the whole field of view (FOV) regardless of spatially variant motion blurring effects, which compromises image quality by under-gating regions of large motion and over-gating static regions. To achieve the best resolution-noise trade-off for the whole FOV, we proposed a new approach that incorporates spatially variant number of gates into gated image reconstruction. The first step is to estimate motion amplitude of each spatial location...
