Glyphosate-tolerant (GT) soybeans dominate the world soybean market. These plants have triggered increased use of, as well as increased residues of, glyphosate in soybean products. We present data that show farmers have doubled their glyphosate applications per season (from two to four) and that residues of late season spraying of glyphosate (at full bloom of the plant) result in much higher residues in the harvested plants and products. GT soybeans produced on commercial farms in the USA, Brazil and Argentina accumulate in total an estimated 2500–10,000 metric tonnes of glyphosate per year, which enter global food chains. We also review studies that have compared the quality of GT soybeans with conventional and organic soybeans. Feeding studies in Daphnia magna have shown dose-related adverse effects (mortality, reduced fecundity and delayed reproduction) of glyphosate residues in soybeans, even at glyphosate concentrations below allowed residue levels. We argue that GT soybeans need to be tested in fully representative and realistic contexts. However, the current risk assessment system has only required and received data from field trials with beans that were sprayed with much lower doses of glyphosate as compared to contemporary commercial farms. This has left knowledge gaps and a potentially serious underestimation of health risks to consumers.

AbstractObjectiveTo compare energy (calories), total and saturated fats, and Na levels for ‘kids’ menu’ food items offered by four leading multinational fast-food chains across five countries.DesignA content analysis was used to create a profile of the nutritional content of food items on kids’ menus available for lunch and dinner in four leading fast-food chains in Australia, Canada, New Zealand, the UK and the USA.SettingFood items from kids’ menus were included from four fast-food companies: Burger King, Kentucky Fried Chicken (KFC), McDonald's and Subway. These fast-food chains were selected because they are among the top ten largest multinational fast-food chains for sales in 2010, operate in high-income English-speaking countries, and have a specific section of their restaurant menus labelled ‘kids’ menus’.ResultsThe results by country indicate that kids’ menu foods contain less energy (fewer calories) in restaurants in the USA and lower Na in restaurants in the UK. The results across companies suggest that kids’ menu foods offered at Subway restaurants are lower in total fat than food items offered at Burger King and KFC, and food items offered at KFC are lower in saturated fat than items offered at Burger King.ConclusionsAlthough the reasons for the variation in the nutritional quality of foods on kids’ menus are not clear, it is likely that fast-food companies could substantially improve the nutritional quality of their kids’ menu food products, translating to large gains for population health.

Introduction: There is a decline in male fertility thus new treatments are needed. Aims: To test the efficacy of a new dietary supplement developed in the USA and registered as a curing drug in Hungary (OGYI). Methods: In a clinical trial 100 men with low sperm quality (spermium count 5–20 M/ml, good motility 10–40%, and adverse shape 30–50%) were examined. Results: Sperm parameters were measured before and after a 3-month treatment and after another 3-month without treatment. This dietary supplement statistically and clinically significantly improved sperm count and motility. In 74 cases this dietary supplement demonstrated a beneficial effect on sperm quality (more than 10% increase in sperm count, or quality of motility, or shape); in 16 cases the improvement exceeded 30%. No adverse effect could be accounted for this treatment. Conclusions: This new dietary supplement may contribute to the treatment of male infertility. Orv. Hetil., 2012, 153, 1787–1792.

The Right

Substituted judgment has increasingly become the accepted standard for rendering decisions for incapacitated adults in the USA. A broad exception exists with regard to patients with diminished capacity secondary to depressive disorders, as such patients’ previous wishes are generally not honoured when seeking to turn down life-preserving care or pursue aid-in-dying. The result is that physicians often force involuntary treatment on patients with poor medical prognoses and/or low quality of life (PMP/LQL) as a result of their depressive symptoms when similarly situated incapacitated patients without such depressive symptoms would have their previous wishes honoured via substituted judgment. This commentary argues for reconsidering this approach and for using a substituted judgment standard for a subset of EMP/LQL patients seeking death.

The impact of sleep disorders (SDs) on patients with chronic liver diseases (CLD) is tremendous. SDs are frequently encountered among these patients and interfere with their quality of life. This review aims to present the data available so far about the prevalence, phenotypes, and proposed pathophysiological mechanisms of SDs in CLD. Moreover, we proposed to search the literature regarding the most reliable methods to assess SDs and the possible therapeutic options in patients with CLD. The main results of this review show that when it comes to prevalence, the percentages reported vary widely between studies performed among populations from the USA or Europe and those coming from Asian countries. Furthermore, it has been proven that SDs may also be present in the absence of neurocognitive disorders attributable to hepatic encephalopathy (HE), which contradicts traditional suppositions where SDs were considered part of the clinical scenario of HE. Currently, there are no specific recommendations or protocols to assess SDs in CLD patients and data about the therapeutic management are limited. Taking into consideration their impact, a protocol for diagnosing and managing SDs should be developed and included in the daily practice of hepatologists.

Main Determinants

Fruit quality is certainly influenced by biotic and abiotic factors, and a main quality attribute is the external appearance of the fruit. Various possible agronomical approaches are able to regulate the fruit microenvironment and, consequently, improve fruit quality and market value. Among these, fruit bagging has recently become an integral part of fruits’ domestic and export markets in countries such as Japan, China, Korea Australia and the USA because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. Despite increasing global importance, the development of suitable bagging materials and, above all, their use in the field is quite laborious, so that serious efforts are required to enhance and standardize bagging material according to the need of the crops/fruits. This review provides information about the effects of bagging technique on the fruit aspect and texture, which are the main determinants of consumer choice.

SummaryWe are still confronted by numerous different nosographic models and problems concerning the objective evaluation of patients progress during treatment. It is interesting to consider the consequences of this situation in psychiatry which still involves a relative diversity of practical methods used in clinical trials. The recommendations of the USA Food and Drug Administration, on the one hand, constitute a highly structured and precise reference. The World Health Organization, on the other hand, promulgates general recommendations resulting from a compromise designed to satisfy the greatest number of clinicians.Despite the apparently diverse principles and the different practical methods they propose, both those sets of recommendations have been useful in inspiring clinicians to reflect upon these different methodological approaches. The qualities of the inclusion criteria used in the study of patients and the sensitivity of the different measuring instruments have allowed psychotropic drug users as well as producers to recognize the need for a certain rigour in clinical trials.The FDA and WHO guidelines have certainly improved the quality of clinical trials in psychopharmacology. However, they also represent a source of resistance to innovation.A series of consensus meetings to first reconcile US and European points of view and later to include new techniques in the recognized sets of methods would therefore be helpful.

This study determined residual buprofezin levels in fresh ginseng and evaluated their changes during processing. Supervised field trials were conducted at Yeongju, Geumsan, and Goesan, Korea. Buprofezin 12.5% EC was applied to 5-y ginseng in accordance with the Korean good agriculture practice (GAP). Samples were collected at 0, 7, 14, 21, and 30 d after the final application. On day 14 (GAP-equivalent preharvest date), the ginseng was processed to obtain dried and red ginseng. The average buprofezin concentrations on day 0 were 0.076 (Yeongju), 0.055 (Geumsan), and 0.078 mg kg−1 (Goesan). Residual concentrations increased as ginseng was processed into dried and red ginseng. Residue levels in dried ginseng manufactured by hot air drying were higher than in red ginseng obtained by steaming, hot air, and sunlight drying. However, the absolute amount of pesticides decreased by approximately 20–30% as a result of calculating the reduction factor considering the dry yield and moisture content. Therefore, the residual concentration in processed products may vary depending on the processing method, and it is deemed necessary to consider the processing yield and moisture content when evaluating the safety of residual pesticides in dried processed products.

Aim - the search, analysis and systematization of historical facts concerning the formation and evo-lution of the world medical standartization; severance of its certain long-standing models for the optimization of settling and introduction of the existing, and future analogs, particularly, in the clinical audit format. Material and Methods. In order to study the medical standard as a historical component the fol-lowing methods were used: bibliographic, historical, analytical and methods of systematization and comparison. Results and Discussion. As a result of the conducted research the main historical events in the world development of the medical standartization starting from 1500 up till nowadays were col-lected. In order to study the evolution of the medical standartization, the analysis of the normative documents that have regulated the process of standartization, especially the Doctor's statute(s) in Russia, Minimal standard of the medical equipment and works of the American college of surgeons, was carried out. The scientific works that initiated the introduction of the clinical audit in the Health Care system in Ukraine, Turkey, the USA and Great Britain were throroughly analyzed. Conclusions. The improvement of quality as to rendering the medical aid is a job priority in the health care systems in many countries. For that reason, the search for its optimization was and is still retrieved for many centuries. The territorial formation of medical standartization is associated with England, Russia and the USA, but the occurrence of clinical audit is connected with Ukraine, Turkey, the USA and Great Britain. The foundations of the medical standardization was lauched in 1500 year, while the clinical audit - in 1854 year. The medical standartization is a reflection of the history of development of the organization of health care system, that's why the expertness (knowl-edge) of historical stages concerning the setting and the introduction of medical standartization may give a new impulse in its improvement and development under present-day conditions of reforma-tion in the medical sphere in Ukraine. The earlier beginning of implementation of the medical stan-dartization in the health care system in different countries makes it possible to actualize its introduc-tion into the clinical audit format, that, in its turn, allows to improve the quality of rendering the medical aid. Key words: medical standartization, clinical audit, quality of medical aid

Biotic Integrity Index

<p>A Lake Multi-biotic Integrity Index (LMII) for the China’s second largest interior lake (Dongting Lake) was developed to assess the water quality status using algal and macroinvertebrate metrics. Algae and benthic macroinvertebrate assemblages were sampled at 10 sections across 3 subregions of Dongting Lake. We used a stepwise process to evaluate properties of candidate metrics and selected ten for the LMII: Pampean diatom index, diatom quotient, trophic diatom index, relative abundance diatoms, Margalef index of algae, percent sensitive diatoms, % facultative individuals, % Chironomidae individuals, % predators individuals, and total number of macroinvertebrate taxa. We then tested the accuracy and feasibility of the LMII by comparing the correlation with physical-chemical parameters. Evaluation of the LMII showed that it discriminated well between reference and impaired sections and was strongly related to the major chemical and physical stressors (r = 0.766, P&lt;0.001). The re-scored results from the 10 sections showed that the water quality of western Dongting Lake was good, while that of southern Dongting Lake was relatively good and whereas that of eastern Dongting Lake was poor. The discriminatory biocriteria of the LMII are suitable for the assessment of the water quality of Dongting Lake. Additionally, more metrics belonging to habitat, hydrology, physics and chemistry should be considered into the LMII, so as to establish comprehensive assessment system which can reflect the community structure of aquatic organisms, physical and chemical characteristics of water environment, human activities, and so on.</p>
