Growing up in Ireland. Key findings: 13-year-olds. No. 2. Physical activity and obesity among 13-year-olds.

This Key Finding reports on data from the second wave of interviews with Growing Up in Ireland's Child Cohort. The 8,568 children and their families were first interviewed when the children were 9 years old, and then at age 13 years, when 7,400 were reinterviewed between August 2011 and February 2012.The findings show that boys and young people from more socially advantaged backgrounds were more likely to exercise, and that 13-year-olds who took more exercise (whether hard or light exercise) were less likely to be overweight or obese.While most of the young people in Growing Up in Ireland maintained a healthy weight over time, one in four was either overweight or obese, a finding similar to that at 9 years. Girls were also more likely to be classified as overweight or obese than boys. The majority of 13-year-olds were quite positive about their physical appearance, although a quarter rated themselves as below average in this respect, and girls tended to be less positive about their body image than boys. Dieting behaviours had also become evident at 13.To understand more fully the origins and course of overweight and obesity, the descriptive data in this Key Finding can be used in more complex analyses drawing on the rich data available on the child, family and other important contextual variables.This resource was contributed by the National Documentation Centre on Drug Use.

Biochemical analysis of female mice urine with reference to endocrine function: a key tool for estrus detection.

Species-specific chemical signals released through urine, sweat, saliva and feces are involved in communication between animals. Urinary biochemical constituents along with pheromones may contribute to variation across reproductive cycles and facilitate to estrus detection. Hence, the present study was designed to analyze such biochemical profiles, such as proteins, carbohydrates, lipids, fatty acids, in response with steroid hormones such as estradiol and progesterone. The experimental groups were normal, prepubertal, ovariectomized, and ovariectomized with estrogentreated female mice. In normal mice, the protein and lipid concentrations in urine were significantly higher in proestrus and estrus phases and the quantity of fatty acids was also comparatively higher in estrus. Furthermore, certain fatty acids, namely tridecanoic, palmitic and oleic acids, were present during proestrus and estrus phases, but were exclusively absent in ovariectomized mice. However, the carbohydrate level was equally maintained throughout the four phases of estrous cycle. For successful communication, higher concentrations of protein and specific fatty acids in estrus are directly involved. The significant increase in estradiol at estrus and progesterone at metestrus seems to be of greater importance in the expression pattern of biochemical constituents and may play a notable role in estrous cycle regulation. Thus, we conclude that the variations observed in the concentration of the biochemical constituents depend on the phase of the reproductive cycle as well as hormonal status of animals. The appearance of protein and specific fatty acids during estrus phase raises the possibility to use these as a urinary indicators for estrus detection.

Further observations on clinical, histopathological, and immunological features of borderline disseminated cutaneous leishmaniasis caused by Leishmania (Leishmania) amazonensis

Leishmania (Leishmania) amazonensis has for some time been considered as the causative agent of two distinct forms of American cutaneous leishmaniasis (ACL): localized cutaneous leishmaniasis (LCL), and anergic diffuse cutaneous leishmaniasis (ADCL). Recently, a new intermediate form of disease, borderline disseminated cutaneous leishmaniasis (BDCL), was introduced into the clinical spectrum of ACL caused by this parasite, and in this paper we record the clinical, histopathological, and immunological features of eight more BDCL patients from Brazilian Amazonia, who acquired the disease in the Pará state, North Brazil. Seven of them had infections of one to two years' evolution and presented with primary skin lesions and the occurrence of metastases at periods varying from six to 12 months following appearance of the first lesion. Primary skin lesions ranged from 1-3 in number, and all had the aspect of an erythematous, infiltrated plaque, variously located on the head, arms or legs. There was lymphatic dissemination of infection, with lymph node enlargement in seven of the cases, and the delayed hypersensitivity skin-test (DTH) was negative in all eight patients prior to their treatment. After that, there was a conversion of DTH to positive in five cases re-examined. The major histopathological feature was a dermal mononuclear infiltration, with a predominance of heavily parasitized and vacuolated macrophages, together with lymphocytes and plasma cells. In one case, with similar histopathology, the patient had acquired his infection seven years previously and he presented with the largest number of disseminated cutaneous lesions. BDCL shows clinical and histopathological features which are different from those of both LCL and ADCL, and there is a good prognosis of cure which is generally not so in the case of frank ADCL.

Severity of endoscopically detected esophageal inflammatory and fibrostenotic features correlates with degree of esophageal eosinophilia in adults with eosinophilic esophagitis

Background: Eosinophilic esophagitis (EoE) has emerged as a leading cause of dysphagia in adults. Characteristic esophageal features on endoscopy include structural/fibrostenotic (rings, narrow caliber, strictures) and inflammatory manifestations (longitudinal furrows, exudates, edema). Aim: The purpose of this study was to correlate the clinical, endoscopic and histopathologic features in adult EoE patients. Methods: A total of 106 encounters of 81 patients with EoE were analyzed. Data included an EoE-directed symptom-severity patient questionnaire evaluating symptoms of dysphagia (frequency, intensity, duration), meal duration, chest pain, and overall symptom severity. Video recordings of endoscopies were reviewed in a blinded manner using a classification and grading scheme for the esophageal features of EoE. Histopathology was reviewed for peak eosinophil count/high power field by pathologists blinded to the patients' clinical status. Associations between endoscopic features, histology and symptoms were evaluated using the Spearman rank correlation analysis. Results: The endoscopic severity of both structural and inflammatory esophageal features of EoE, including rings, exudates, longitudinal furrows, and edema, correlated significantly with peak eosinophil counts (see Table 1). Presence of "crepe paper mucosa" did not demonstrate significant association with peak eosinophil counts. Both structural (rings, narrow-caliber esophagus and strictures) and inflammatory (furrows, exudates and edema) composite endoscopic scores demonstrated a strong correlation with peak eosinophil counts. The strongest association with the degree of esophageal eosinophilia was found with a combination of both structural and inflammatory findings (p < 0.0001). The esophageal diameter (in mm) was negatively correlated with overall symptom severity (Spearman's rho = -0.4883, P = 0.0339). None of the individual or combined patient reported symptoms correlated significantly with either endoscopic or histopathologic findings. Conclusion: The severity of both structural and inflammatory endoscopic features associated with EoE is significantly associated with the degree of esophageal eosinophilia. Patient reported symptom severity was not associated with the degree of esophageal eosinophilia. Esophageal stricture diameter was inversely correlated with EoE symptom severity. The prognostic and therapeutic implications of these observations need to be determined.

Corneal Opacities in Trisomy 8 Mosaic Syndrome : Clinical, Histologic and Genetic Features

Purpose: To describe the clinical, histologic and genetic findings of corneal opacities in the trisomy 8 mosaic syndrome. Methods: 3 children aged 8 years (Patients A), 6 years (Patients B) and 1 month (Patients C) respectively, were referred with corneal opacities for ophthalmologic evaluation. The 2 older patients had been previously diagnosed with trisomy 8 mosaicism, while the third was diagnosed after the ocular examination. Automated lamellar keratoplasty (ALTK) was performed on the most amblyopic eye. Histopathologic analysis with immunohistochemical markers and cytogenetic studies by FISH using haploid probes for chromosome 8 and chromosome 16 (control) were performed on the excised corneal lesion. Results: All patients presented vascularized corneal opacities involving the superficial stroma, and amblyopia with a bilateral involvement in two of them (Patients A and B). Post-operative follow-up (range 6-20 months) was satisfactory, with the graft remaining clear and improved visual acuity, allowing iso-acuity and stereoscopy in the one month old child (Patients C). The clinically observed corneal opacities corresponded histopathologically to the replacement of the normal anterior corneal stroma by a choristomatous loose richly vascularized connective tissue containing mucopolysacharides. Bowman's membrane was absent. There were no adnexal structures. The overlaying epithelium expressed keratin 3 in all three cases. Keratin 19 was found in the suprabasal epithelial cells in one case but was absent in the other cases. There were no expression of keratin 7 and 1 as well as MUC5AC in the epithelial cells. FISH analysis from 100 interphase cells of the affected tissue and normal conjontival probe revealed normal diploid cells. Conclusions: In this series, the corneal opacities associated with trisomy 8 mosaic syndrome share a common clinical, histopathological and genetic features. ALTK should be considered at diagnosis to prevent amblyopia in these children.

A key transcription cofactor on the nascent sex chromosomes of European tree frogs (Hyla arborea)

We show that MED15, a key component of the transcription complex Mediator, lies within the nonrecombining segment of nascent sex chromosomes in the male-heterogametic Hyla arborea. Both X and Y alleles are expressed during embryonic development and differ by three frame-preserving indels (eight amino acids in total) within their glutamine-rich central part. These changes have the potential to affect the conformation of the Mediator complex and to activate genes in a sex-specific way and might thus represent the first steps toward the acquisition of a male-specific function. Alternatively, they might result from an ancestral neutral polymorphism, with different alleles picked by chance on the X and Y chromosomes when MED15 was trapped in the nonrecombining segment.

Constitutively active alpha-1b adrenergic receptor mutants display different phosphorylation and internalization features.

We compared the phosphorylation and internalization properties of constitutively active alpha-1b adrenergic receptor (AR) mutants carrying mutations in two distant receptor domains, i.e., at A293 in the distal part of the third intracellular loop and at D142 of the DRY motif lying at the end of the third transmembrane domain. For the A293E and A293I mutants the levels of agonist-independent phosphorylation were 150% and 50% higher than those of the wild-type alpha-1b AR, respectively. On the other hand, for the constitutively active D142A and D142T mutants, the basal levels of phosphorylation were similar to those of the wild-type alpha-1b AR and did not appear to be further stimulated by epinephrine. Overexpression of the guanyl nucleotide binding regulatory protein-coupled receptor kinase GRK2 further increases the basal phosphorylation of the A293E mutant, but not that of D142A mutant. Both the wild-type alpha-1b AR and the A293E mutant could undergo beta-arrestin-mediated internalization. The epinephrine-induced internalization of the constitutively active A293E mutant was significantly higher than that of the wild-type alpha-1b AR. In contrast, the D142A mutant was impaired in its ability to interact with beta-arrestin and to undergo agonist-induced internalization. Interestingly, a double mutant A293E/D142A retained very high constitutive activity and regulatory properties of both the A293E and D142A receptors. These findings demonstrate that two constitutively activating mutations occurring in distant receptor domains of the alpha-1b AR have divergent effects on the regulatory properties of the receptor.

Re-mapping the molecular features of the human immunodeficiency virus type 1 and human T-cell lymphotropic virus type 1 Brazilian sequences using a bioinformatics unit established in Salvador, Bahia, Brazil, to give support to the viral epidemiology studies

The analysis of genetic data for human immunodeficiency virus type 1 (HIV-1) and human T-cell lymphotropic virus type 1 (HTLV-1) is essential to improve treatment and public health strategies as well as to select strains for vaccine programs. However, the analysis of large quantities of genetic data requires collaborative efforts in bioinformatics, computer biology, molecular biology, evolution, and medical science. The objective of this study was to review and improve the molecular epidemiology of HIV-1 and HTLV-1 viruses isolated in Brazil using bioinformatic tools available in the Laboratório Avançado de Sáude Pública (Lasp) bioinformatics unit. The analysis of HIV-1 isolates confirmed a heterogeneous distribution of the viral genotypes circulating in the country. The Brazilian HIV-1 epidemic is characterized by the presence of multiple subtypes (B, F1, C) and B/F1 recombinant virus while, on the other hand, most of the HTLV-1 sequences were classified as Transcontinental subgroup of the Cosmopolitan subtype. Despite the high variation among HIV-1 subtypes, protein glycosylation and phosphorylation domains were conserved in the pol, gag, and env genes of the Brazilian HIV-1 strains suggesting constraints in the HIV-1 evolution process. As expected, the functional protein sites were highly conservative in the HTLV-1 env gene sequences. Furthermore, the presence of these functional sites in HIV-1 and HTLV-1 strains could help in the development of vaccines that pre-empt the viral escape process.
