Depression, anxiety and pain in children with juvenile idiopathic arthritis (JIA).

The aim of this study was to assess relations among depression, anxiety and pain in children with juvenile idiopathic arthritis (JIA). Pain was measured with the visual analogue scale (VAS), and depression and anxiety with depression and anxiety subscales from the Trauma Symptom Checklist for Children (TSC-C). Pain perception was significantly correlated with depression scores.     

Markers of inflammation and microvascular complications in type 1 diabetes

Aims

Long-term hyperglycemia, characteristic for type 1 diabetes, causes enhanced oxidative stress, chronic inflammation and endothelial dysfunction which are the key events in the development of vascular complications. On the other hand, some data shows that existence of chronic degenerative complications may cause increased inflammatory marker levels in diabetic patients, mainly as a repercussion of malfunctioned endothelial repair process. Our study aims to determinate a degree of inflammation in type 1 diabetes patients and to investigate its relation to development of the chronic microvascular complications.

Methods

General information, anthropometric, glucose metabolism, lipid and lipoprotein parameters, levels of C reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were analyzed and screening tests for detection of the chronic microvascular complications were conducted in 76 type 1 diabetes patients.

Results

Forty six patients had at least one of the complications. They were older and had longer duration of diabetes (p=0.015; p<0.0001) and higher values of total (p=0.021), LDL-cholesterol (p=0.048) and triglycerides (p=0.002). Levels of CRP (p=0.004) and TNF-α (p=0.048) were higher in patients with chronic microvascular complications in regard to patients without diagnosed microangiopathy.

Conclusion

Low grade chronic inflammation is characteristic for type 1 diabetes patients with developed chronic microvascular complications.     

Isocratic RP-HPLC method for rutin determination in solid oral dosage forms

A rapid and sensitive assay for quantitative determination of rutin in oral dosage forms based on isocratic reversed phase high performance liquid chromatography (RP-HPLC) was developed and validated. Using a C(18) reverse-phase analytical column, the following conditions were chosen as optimal: mobile phase methanol-water 1:1 (v/v), pH 2.8 (adjusted with phosphoric acid), flow rate=1 mL min(-1) and temperature T=40.0 degrees C. Linearity was observed in the concentration range 8-120 microg mL(-1) with a correlation coefficient of 0.99982 and the limit of detection (LOD)=2.6 microg mL(-1), and limit of quantification (LOQ)=8.0 microg mL(-1). Intra- and inter-day precision were within acceptable limits. Robustness test indicated that the mobile phase composition and pH influence mainly the separation. The proposed method allowed direct determination of rutin in pharmaceutical dosage forms in the presence of excipients, but is not suitable for preparations where compounds structurally/chemically related to rutin may be present.     

Pesticides and their binary combinations as P-glycoprotein inhibitors in NIH 3T3/MDR1 cells

The purpose of the present study was to assess do selected pesticides as well as their binary combinations act as inhibitors of P-glycoprotein (P-gp) activity of NIH 3T3 mouse fibroblasts stably transfected with human MDR1 gene (NIH 3T3/MDR1). As a result of P-gp inhibition, the increase of intracellular accumulation of a model P-gp substrate fluorescent calcein acetoxymethyl ester was measured. Pesticide and verapamil individual dose–response data were scaled and expressed as percent of maximum effect. Results showed that out of 14 pure pesticides tested, endosulfan, phosalone and propiconazole were nearly as potent as model inhibitor verapamil (EC₅₀ = 1.5 μM), while diazinon showed a lower potency of inhibiting P-gp transport activity (EC₅₀ = 58.4 μM). Concentrations of pesticides that produced the same inhibiting effect (isoboles) were combined binary. Results calculated using the isobole method revealed that diazinon caused synergistic effect in inhibiting P-gp transport activity in all combinations.     

Assessment of toxicological profiles of the municipal wastewater effluents using chemical analyses and bioassays

The hazardous chemical contamination of untreated wastewater and secondary effluent from the wastewater treatment plant (WWTP) of the city of Zagreb, Croatia was comprehensively characterized using large-volume solid-phase extraction (SPE) and silica gel fractionation, followed by a detailed analysis of the resulting extracts by a combination of chemical and bioassay methods. Over 100 individual contaminants or closely related-contaminant groups were identified by high-resolution gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/quadrupole time-of-flight mass spectrometry (LC-QTOF). Ecotoxicity profiling of the investigated samples, including cytotoxicity, chronic toxicity and EROD activity; inhibition of the multixenobiotic resistance (MXR), genotoxicicity and estrogenic potential, revealed the most significant contribution of toxic compounds to be present in polar fractions. Wastewater treatment using conventional activated sludge process reduced the initial toxicity of raw wastewater to various extents, ranging from 28% for algal toxicity to 73.2% for an estrogenic activity. The most efficient toxicity removal was observed for the polar compounds.     

What is the gold standard for intrapartum fetal monitoring?

The health authorities of Stockholm county recently published a Health Technology Assessment report: "Fetal monitoring with computerized STAN analysis during labor - a systematic review" with the aim to ensure that high quality research information on costs, effectiveness and broader impact of health technologies is analysed and presented in the most efficient way for those who use, manage and work in this field. The report claims to analyse available research in relation to ST interval analysis of fetal electrocardiogram (STAN) and concludes that scientific evidence for advantages of the STAN technology for maternal and fetal outcome was insufficient and that clinical use cannot be recommended and should be restricted to research protocols. The Norwegian reference group for fetal surveillance points out that the report suffers from two insufficiencies: selection bias by not providing a complete collection of the evidence for the clinical performance of the STAN technology and, secondly, that it does not provide evidence-based alternative methods.     

How three countries in the Americas are fortifying dietary salt reduction: A north and south perspective

A chronic disease/risk factor prevention framework with three policy environments - communications, physical and economic - was used to organize population level interventions that address the “over consumption of dietary salt”, a key risk factor for cardiovascular diseases. The framework was then used to map the population based strategies to reduce dietary salt consumption being applied in three countries in the Americas - Argentina, Canada and Chile - each with a history of multi-sector approaches to deal with the risk factors for chronic disease, offering a north versus south perspective.Results show that in all three countries policy instruments are concentrated in the communications environment, e.g. media and education campaigns and/or regulations for standardized information on the salt or sodium content of packaged food products. Notable gaps are the requirement for nutrient information on meals and food items prepared by food establishments and restrictions on advertising and marketing of foods to children. In the physical environment, referring to the sodium levels in commercially prepared foods and meals available on the market, voluntary reformulation of food products is underway at this time in the three countries. Argentina and Chile began with bread and have gradually added other food categories; Canada at the outset is addressing all food categories where products have added salt. Argentina alone is at this point actively approaching regulations to limit the salt content of food, preferring this over ongoing monitoring of voluntary targets. No government in the three counties has yet considered action in the economic environment, a complex area where the research on and initiatives to limit or disadvantage energy-dense food products to address obesity may also capture foods that are highly salted. In the meantime, with recent research estimating substantially higher gains in population health from government legislation to limit salt in foods compared to voluntary approaches, decision makers in countries, whether in the north or south, committed to reducing dietary salt can take Argentina's example to strengthen their interventions in the physical environment with regulatory instruments. This will sustain reformulations made to date, “level the playing field” industry-wide and broadly and equitably distribute the health benefits of low salt foods.
