Papel da polissonografia na avaliação das obstruções das vias aéreas em lactentes : relato de dois casos
Ronco habitual e apnéia obstrutiva observada em adultos: estudo de base populacional, Pelotas, RS
OBJECTIVE: To estimate the prevalence of habitual snoring and obstructive sleep apnea and their factors associated. METHODS: Cross-sectional study with a representative sample comprising 3,136 adults (>;20 years) living in the city of Pelotas, Southern Brazil, in 2005. A questionnaire was used to collect information on demographic, socioeconomic, behavioral and anthropometric variables and outcomes. Crude and adjusted statistical analysis using Fisher exact test and chi-square test for linear trend and a multivariate analysis through Poisson regression model were carried out, respectively. RESULTS: The prevalence of habitual snoring was 50.5% (95% CI: 48.1;52.8) and obstructive sleep apnea was 9.9% (95% CI: 8.7;11.2). After adjustment, the risk of habitual snoring was greater in males (prevalence ratio [PR]=1.25, 95% CI: 1.16;1.34), elderly people (PR=1.62, 95% CI: 1.46;1.80), current smokers (PR=1.15, 95% CI: 1.07;1.25), alcohol users (PR=1.17, 95% CI: 1.03;1.31) and obese people (PR=1.71, 95% CI: 1.55;1.88). The risk of obstructive sleep apnea was greater in males (PR=2.05, 95% CI: 1.67;2.52), elderly people (PR=2.23, 95% CI: 1.64;3.03), current smokers (PR=1.60, 95% CI: 1.25;2.05) and obese people (PR=2.61, 95% CI: 1.97;3.47). CONCLUSIONS: In the studied population, habitual snoring and obstructive sleep apnea were common symptoms. Well-known risk factors such as male gender and age between 40 and 60 years are not modifiable. However, smoking, alcohol use and obesity need to be identified and treated in general population.OBJETIVO: Estimar a prevalência de ronco habitual e apnéia obstrutiva observada e fatores associados. MÉTODOS: Estudo transversal com amostra representativa de 3.136 adultos, com 20 anos ou mais, residentes em Pelotas, Rio Grande do Sul, em 2005. Informações sobre os desfechos e variáveis demográficas, socioeconômicas, comportamentais e antropométricas foram coletadas por meio de questionário. A análise estatística bruta e ajustada foi realizada utilizando-se teste exato de Fisher ou qui-quadrado de tendência linear e regressão de Poisson, respectivamente. RESULTADOS: A prevalência encontrada de ronco habitual foi de 50,5% (IC 95%: 48,1;52,8) e de apnéia obstrutiva de 9,9% (IC 95%: 8,7;11,2). Na análise ajustada, o relato de ronco foi maior nos homens (Razão de Prevalências - RP=1,25; IC 95%: 1,16;1,34), nos idosos (RP=1,62; IC 95%: 1,46;1,80), nos tabagistas (RP=1,15; IC 95%: 1,07;1,25), nos alcoolistas (RP=1,17; IC 95%: 1,03;1,31) e nos obesos (RP 1,71, IC95% 1,55;1,88). O relato de apnéia obstrutiva foi maior nos homens (RP=2,05; IC 95%: 1,67;2,52), nos idosos (RP=2,23; IC 95%: 1,64;3,03), nos tabagistas (RP=1,60; IC 95%: 1,25;2,05) e nos obesos (RP=2,61; IC 95%: 1,97;3,47). CONCLUSÕES: Ronco habitual e apnéia obstrutiva foram sintomas comuns na população estudada. Fatores de risco conhecidos como sexo masculino e idade entre quarta e quinta décadas de vida não são modificáveis. Entretanto, tabagismo, alcoolismo e obesidade também associados aos desfechos, devem ser identificados e tratados na população geral
The potential role of advanced glycation end products in food allergy pathogenesis
prevalence has dramatically increased in the last two
decades. Among dietary factors, it has been
hypothesized that advanced glycation
endproducts(AGEs), present at high level in junk food, could be
involved in FA pathogenesis. AGEs are a heterogeneous group of
compounds deriving from sugars(sweets and beverages),
autoclaved/processed foods, microwaved foods, more
roasted/barbecued meat. To evaluate the AGEs levels in FA children
compared with healthy controls and subjects with respiratory allergy.
Methods: We evaluated paediatric patients with challenge-proven FA,
children with respiratory allergy(RA) and age and sex-matched healthy
controls. Subcutaneous AGEs levels were evaluated through the AGE
reader. Food-frequency questionnaires were evaluated in all study
subjects.
In vitro studies were performed on human enterocytes(Caco-2 cells)
stimulated with 200 mg/ml of BSA-AGE for 24and48 hours to evaluate
effects on gut barrier function: mucin2(mucus production),
transpithelial electrical resistance(TEER), ZO-1, occludin
expression(intestinal permeability). The direct effects elicited on
peripheral blood mononuclear cells (PBMCs) after the treatment with
200 mg/ml of BSA-AGE for 48hours, 4and 7days of treatment were
also evaluated.
RESULTS: 115 subjects were evaluated and subdivided into 3 groups:
group 1 patients with FA (n=31); group 2 patients with RA (n=18),
group 3 healthy controls (n=66). The consumption of food containing
AGEs was higher in subjects with FA compared to RA children and
healthy controls (p<0.05). FA and RA children presented significant
higher subcutaneous AGEs levels compared to healthy controls
(p<0.05). Linear regression analysis confirmed a significant positive
correlation between subcutaneous levels of AGEs and consumption of
food containing AGEs. Human enterocytes exposed to BSA-AGE
treatment showed a reduction of TEER, of Muc2 and tight junction
proteins (Occludin and ZO-1). Moreover, the treatment with BSA-AGE
on human PBMCs stimulates pro-inflammatory cytokines TNF-α and
Th2 cytokines(IL-5 and IL-13)production , but it was unable to
modulate IL-10 production. Finally, after7days of treatment with BSAAGE, we found a low percentage of proliferating CD4+T.
CONCLUSIONS: Current hypotheses and models of FA do not
adequately explain the dramatic increase observed in the last years
