Caregiver-reported antiretroviral therapy non-adherence during the first week and after a month of treatment initiation among children diagnosed with HIV in Ethiopia

To achieve optimal virologic suppression for children undergoing antiretroviral therapy (ART), adherence must be excellent. This is defined as taking more than 95% of their prescribed doses. To our knowledge, no study in Ethiopia has evaluated the level of treatment adherence at the beginning of the child's treatment. Our aim was therefore to evaluate caregiver-reported ART non-adherence among chi

Institutional change and the optimal size of universities

The last years have been characterized by tremendous institutional change in the university sector induced by far-reaching Higher Education Reforms (e.g. Bologna). Building on loose-coupling theory, we hypothesize that smaller universities were better able to adapt to the Higher Education Reforms of the recent years, triggering a decline in the optimal size of universities in the reform period. Us

Learning to be inflexible : Enhanced attentional biases in Parkinson's disease

Impaired attentional flexibility is considered to be one of the core cognitive deficits in Parkinson's disease (PD). However, the mechanisms that underlie this impairment are contested. Progress in resolving this dispute has also been hindered by the fact that cognitive deficits in PD are heterogeneous; therefore, it is unclear whether attentional impairments are only present in a subgroup of pati

Rapid test for lung maturity, based on spectroscopy of gastric aspirate, predicted respiratory distress syndrome with high sensitivity

Aim: Respiratory distress syndrome (RDS) is a major cause of mortality and morbidity in premature infants. By the time symptoms appear, it may already be too late to prevent a severe course, with bronchopulmonary dysplasia or mortality. We aimed to develop a rapid test of lung maturity for targeting surfactant supplementation. Methods: Concentrations of the most surface-active lung phospholipid di

Evaluation of perfluorohexyloctane/polydimethylsiloxane for pancreas preservation for clinical islet isolation and transplantation

This study aimed to evaluate a 50:50 mix of perfluorohexyloctane/polydimethylsiloxane 5 (F6H8S5) preservation of pancreases in a clinical setting compared with standard solutions for 1) cold ischemia time (CIT) 20 h. Procured clinical-grade pancreases were shipped in either F6H8S5 or in standard preservation solutions, that is, University of Wisconsin (UW) or Custodiol. F6H5S5 was preoxygenated fo

Compressive loading of the murine tibia reveals site-specific micro-scale differences in adaptation and maturation rates of bone

Summary: Loading increases bone mass and strength in a site-specific manner; however, possible effects of loading on bone matrix composition have not been evaluated. Site-specific structural and material properties of mouse bone were analyzed on the macro- and micro/molecular scale in the presence and absence of axial loading. The response of bone to load is heterogeneous, adapting at molecular, m

Rapid subglacial streamlined bedform formation at a calving bay margin

Using the LiDAR-derived Swedish national height model we have identified previously undescribed shallow streamlined glacial bedforms, small-scale drumlins, on the Närke plain in south-central Sweden. These drumlins could only be detected with high-resolution LiDAR, due to both their subtle size and forest cover. In this area the ice margin receded in a subaqueous environment with a proglacial wate

A neglected contribution to monetary theory in the eighteenth century : Anders Wappengren on paper money, floating exchange rates, and purchasing power parity

Between 1789 and 1803 the National Debt Office issued unbacked interest bearing notes whereas the Bank of Sweden issued silver backed notes. The massive note issuance by the National Debt Office led to different exchange rates and two units of account. The situation gave rise to an early paper standard theory formulated by Anders Wappengren, a well-read merchant who was strongly influenced by Adam

Bias network and diode parasitics of a reconfigurable stacked microstrip patch antenna at 60 GHz

We present results on the implementation of switches for a reconfigurable antenna at 60 GHz. The switches are realized by diodes, which are characterized by measurements on a coplanar waveguide test bed. From the measurements, we extract different circuit models. The models are used as lumped elements in a full wave simulation of a reconfigurable antenna, where it is shown that the different model

Dynamic and static analysis of the shunt capacitors control effect on the long-term voltage instability

This paper concerns the dynamic and static analysis of the effect of shunt capacitor control strategies on the long-term voltage instability. For this purpose a simplified test system called N3area, reflecting the key voltage instability characteristics of NORDIC32 is considered. Two different control strategies for shunt capacitors including the local and neighboring schemes are applied to improv

Pentraxin 3 in serum and synovial fluid of patients with rheumatoid arthritis with and without autoantibodies

Objectives: Pentraxin 3 (PTX3) is a locally produced multifunctional protein involved in inflammation, matrix deposition, and immunity. As patients with seropositive rheumatoid arthritis (RA) have a more severe disease course and higher risk of joint destruction than seronegative patients, the aim of the present study was to examine differences in PTX3 in synovial fluid (SF) (and serum) in seropos

Innovative Gliadin/Glutenin and Modified Potato Starch Green Composites : Chemistry, Structure, and Functionality Induced by Processing

In this study, we combined two wheat proteins, gliadin (Gli)/glutenin (GT), and modified potato starch (MPS) into composites using extrusion. In the Gli/GT-MPS composites, we studied the structural dynamics of proteins and starch, protein-starch interactions, protein properties, and composite morphology in relation to mechanical and barrier properties. Materials with different ratios of Gli/GT and

Mass-flowering crops dilute pollinator abundance in agricultural landscapes across Europe

Mass-flowering crops (MFCs) are increasingly cultivated and might influence pollinator communities in MFC fields and nearby semi-natural habitats (SNHs). Across six European regions and 2 years, we assessed how landscape-scale cover of MFCs affected pollinator densities in 408 MFC fields and adjacent SNHs. In MFC fields, densities of bumblebees, solitary bees, managed honeybees and hoverflies were

A European aerosol phenomenology-5 : Climatology of black carbon optical properties at 9 regional background sites across Europe

A reliable assessment of the optical properties of atmospheric black carbon is of crucial importance for an accurate estimation of radiative forcing. In this study we investigated the spatio-temporal variability of the mass absorption cross-section (MAC) of atmospheric black carbon, defined as light absorption coefficient (σap) divided by elemental carbon mass concentration (mEC). σap and mEC have

Determination of aromatic amines in aqueous extracts of polyurethane foam using hydrophilic interaction liquid chromatography and mass spectrometry

A method is presented for the determination of aromatic amines in aqueous extracts of polyurethane (PUR) foam. The method is based on the extraction of PUR foam using aqueous acetic acid (0.1%, w/v) followed by determination of extracted aromatic amines using hydrophilic interaction liquid chromatography (HILIC) and tandem mass spectrometry (MS/MS) with positive electrospray ionisation. The inject

Symptoms following day surgery : A review of the literature

Aim: The purpose of this paper is to provide a broad-based overview of the current literature regarding patients' experiences of symptoms following day surgery. Background: The advent of new anaesthetic and anti-emetic agents, advanced surgical techniques and the need for reduced costs for inpatient hospital services, has resulted in about 70% of all surgical procedures being undertaken as day sur
