Self‐objectification in the context of breastfeeding: A concept analysis

To increase the overall rate of breastfeeding initiation and duration, factors involved in a mother's decision to breastfeed must be identified. Self‐objectification in the context of breastfeeding was a concept selected for exploring factors associated with negative views of breastfeeding. A concept analysis following the eight‐step Walker & Avant method provides clarity and context to the concept of self‐objectification in the context of breastfeeding. The antecedents of self‐objectification in the context of breastfeeding include living in a culture of sexualization and objectification of women and the internalization of the values of objectification. Attributes of self‐objectification in the context of breastfeeding are a prioritization of physical appearance attributes of the breast over the health benefits of breastfeeding and a preoccupation with physical appearance. Consequences include negative views toward breastfeeding initiation, duration, and public breastfeeding. A concept analysis on self‐objectification in the context of breastfeeding will provide definition and clarity to this phenomenon, lend to theory and measurement, and add literature to the sociocultural factors impacting breastfeeding decisions.     

Role of the environment in the transmission of JC virus

JC virus is etiologically associated with a fatal demyelinating disease known as PML. JCV produces persistent infections in the kidney and is excreted in the urine of healthy individuals and in the urine of PML patients. The characteristics of the JCV excreted in the environment have been studied by analyzing sewage samples from divergent geographical areas. The intergenic region of JCV strains detected in the sewage of Barcelona (Spain), Umeå (Sweden), Nancy (France), Pretoria (South Africa), Patras (Greece), Cairo (Egypt), Washington, D.C. (USA), and diverse areas of Northern India has been sequenced, and the phylogenetic analysis showed their relationships with JCV strains previously described in urine or clinical samples in these geographic areas. The JCV regulatory region of the JCV DNA detected in sewage presented archetypal or archetypal-like regulatory regions with the exception of one of the twenty clones obtained from a sewage sample of the area of Washington, D.C. that presented a tandem repeated structure. Infectivity studies showed that archetypal JCV present in the urine of a pregnant woman productively infected SVG cells. Also JC viral particles showed considerable stability in sewage at 20°C and in front of treatments with acidic pH and trypsin. The high prevalence of JCV in urine and in sewage and the stability of the viral particles observed suggests that contaminated water, food, and fomites could be the vehicles of JCV transmission through the oral route. Virions partially degraded or noninfectious could be a source of JCV DNA and may represent an additional mechanism of entry of viral genes into cells.     

A preliminary study of stress symptoms and nutritional state in children

The aim of this work was to examine the occurrence of stressful events in the lives of children, using the ‘Scale of Infantile Social Readjustment’ (SISR), and the ‘Inventory of Symptoms of Infantile Stress’ (ISIS) to identify the presence of stress symptoms. The results of these evaluations were then used to examine the relationship between the levels of stress and the nutritional state of the children, by correlation. Forty 7–10‐year‐old children were included in the evaluation. From the analysed sample 49 per cent of them were eutrophic (weight/height normal to age), 50 per cent were above weight and 1 per cent was undernourished. Whereas 70 per cent of the girls were eutrophic and 30 per cent were above weight, only 35 per cent of the boys were eutrophic, 60 per cent were above weight and 5 per cent were undernourished. The results obtained in this first study indicated that 45 per cent of eutrophic girls demonstrated symptoms of stress, while 20 per cent of them were asymptomatic (with no symptoms of stress). Of the overweight boys, 30 per cent of them showed symptoms of stress and 35 per cent did not. This study indicated a possible relationship between weight and the symptoms of stress.

Association of single nucleotide polymorphisms of the interleukin-10 promoter gene and susceptibility to primary biliary cirrhosis: immunogenetic differences in Italian and Japanese patients

Several lines of data suggest that genetic factors play an important role in the onset and/or progression of primary biliary cirrhosis (PBC). Since PBC is an autoimmune disease, it is reasoned to assume that genes encoding cytokines may confer susceptibility to disease. Amongst these factors, interleukin-10 (IL-10) has received significant attention. The promoter region of IL-10 gene has three single nucleotide polymorphisms (SNPs) at positions -1082, -819 and -592. To elucidate the association of the three SNPs of IL-10 promoter region with susceptibility of PBC in two different genetic populations, 159 unrelated patients with PBC (94 Italian and 65 Japanese) and 143 local controls (72 Italian and 71 Japanese) were enrolled. SNPs were determined using allele-specific PCR/RFLP. In Italian PBC patients, the frequency of homozygosity for G/G at position -1082 was significantly higher than that of local controls (p < 0.041, OR = 2.44, 95% C.I.; 1.02-5.86). The frequencies of haplotype GCC in PBC patients, possibly linked to higher IL-10 production, were also significant higher than local controls (p < 0.033). However, in Japanese population, there were no significant differences in the three SNPs and haplotypes between PBC patients and controls. Excessive production of IL-10 may play an important role in some populations in modulating the onset of PBC. Further, immunogenetic studies of PBC should take into account ethnic and geographic variations; this makes such studies in heterogeneous population, like the USA, more difficult.     

Prevalence of Middle East Respiratory Syndrome Coronavirus in Dromedary Camels,Tunisia

Free-roaming camels, especially those crossing national borders, pose a high risk for spreading Middle East respiratory syndrome coronavirus (MERS-CoV). To prevent outbreaks, active surveillance is necessary. We found that a high percentage of dromedaries in Tunisia are MERS-CoV seropositive (80.4%) or actively infected (19.8%), indicating extensive MERS-CoV circulation in Northern Africa.     

The effects of somatostatin in the polycystic ovary syndrome.

Eighteen obese women (body mass index 30 +/- 6.1 kg/m2) with hyperinsulinaemia and with the polycystic ovary syndrome took octreotide at the dose of 100 mug s.c. The effect of the drug was assessed on plasma levels of gonadotropins luteinising hormone (LH), follicle stimulating hormone (FSH), of insulin, insulin-like growth factor-1 (IGF-1), androstenedione, testosterone, dehydroepiandrosterone sulphate (DHEAS), sex hormone binding globulin (SHBG) and insulin-like growth factor-binding protein-3 (IGFBP-3). Octreotide significantly reduced LH (31.8%), insulin (52%), IGF-1 (14%), androstenedione (22.6%) and testosterone (20%) and increased IGFBP-3 (25%).     

European Medicines Agency initiatives and perspectives on pharmacogenomics

Pharmacogenomics, the study of variations of DNA and RNA characteristics as related to drug response, has become an integral part of drug development and pharmacovigilance, as reflected by the incorporation of pharmacogenomic data in EU product information. In this short review article, we describe recent European Medicines Agency initiatives intended to support further the implementation of pharmacogenomics in drug development and surveillance so that patients and the public can benefit from advances in genomic science and technology.     

Arzneimittelreaktionen bei antineoplastischen Substanzen

In recent years, several new classes of compounds have successfully been established in the treatment of cancer. They selectively inhibit disturbed signaling pathways or induce anti-tumor immune responses. These novel targeted cancer drugs show a favorable safety profile compared to conventional chemotherapeutic agents. The most important side effects of these anticancer agents include cutaneous reactions and occur in a time-dependant manner and show class-specific patterns. In this review article, we compare the cutaneous side effects of epidermal growth factor inhibitors (EGFRI), multikinase inhibitors (MKI), BRAF inhibitors (BRAFI), mTor inhibitors (mTorI) and immune checkpoint inhibitors and discuss severity-adapted management strategies.
