Maternal neurotic symptoms and infants' risk of developing persistent diarrhoea

A previously calculated predictive model for health risk selects infants who suffer 4-5 times more morbidity than their unselected peers. Preliminary results suggested that this risk is related to maternal neurotic symptomatology. To evaluate this hypothesis, 52 consecutive mothers whose infants had a positive predictive score (Group 1) and 52 in whom this was negative (Group 2) were evaluated by means of Goldberg's General Health Questionnaire (GHQ - 30). A total of 41.9% and 20.5% of the mothers in Groups 1 and 2, respectively, scored above 11 points in GHQ-30, established as the cut off point. It is concluded that among poor urban families in Santiago mothers of infants with high risk of persistent diarrhoea have increased frequency of detectable neurotic symptoms. New programs aimed at this type of infant should include psychological support for their mothers.

Housework, paid work and psychiatric symptoms

OBJECTIVE: To evaluate the hypothesis that work burden, the simultaneous engagement in paid work and unpaid family housework, is a potential risk factor for psychiatric symptoms among women. METHODS: A cross-sectional study was carried out with 460 women randomly selected from a poor area of the city of Salvador, Brazil. Women between 18 to 70 years old, who reported having a paid occupation or were involved in unpaid domestic activities for their families, were eligible. Work burden-related variables were defined as: a) double work shift, i.e., simultaneous engagement in a paid job plus unpaid housework; and b) daily working time. Psychiatric symptoms were collected through a validated questionnaire, the QMPA. RESULTS: Positive, statistically significant associations between high (>7 symptoms) QMPA scores and either double work shift (prevalence ratio -- PR=2.04, 95% confidence interval -- CI: 1.16, 2.29) or more than 10 hours of daily work time (PR=2.29, 95% CI: 1.96, 3.43) were found after adjustment for age, marital status and number of pre-school children. CONCLUSIONS: Major correlates of high QMPA scores are work burden variables. Being married or having pre-school children are also associated with high QMPA scores only when associated with work burden.

Effects of fungal contamination on respiratory symptoms of poultry workers

Exposure to certain fungi (molds) can cause human illness by 3 specific mechanisms: generation of a harmful immune response, direct infection by the organism or/and toxic-irritant effects from mold byproducts. Moulds are considered central elements in daily exposure of poultry workers and can be the cause of an increased risk of occupational respiratory diseases, like allergic and non-allergic rhinitis and asthma.

Effects of fungal contamination on respiratory symptoms of poultry workers

Moulds are considered central elements in daily exposure of poultry workers and can be the cause of an increased risk of occupational respiratory diseases, like allergic and non-allergic rhinitis and asthma. The objective is to evaluate the exposure to different species of moulds in poultries and relate them with respiratory symptoms in poultry workers. Seven Portuguese poultries were analyzed in order to assess air fungal contamination, as well as to evaluate the existence of clinical symptoms associated with asthma and other allergy diseases by European Community Respiratory Health Survey questionnaire.

Climacteric symptoms and quality of life: validity of women's health questionnaire

OBJECTIVE: To evaluate the reliability and validity of the Portuguese version of the Women's Health Questionnaire. METHODS: In order to evaluate the Women's Health Questionnaire (WHQ), an analytical cross-sectional study was carried out at the women's menopause outpatient clinic of a university hospital in São Paulo, Brazil. There were studied 87 women in perimenopause or menopause, defined as experiencing at least one year's absence of menstrual flow. The following variables were collected: demographic data, clinical variables (Kupperman index and correlate numeric scale) and quality of life indexes (SF-36 and utility). RESULTS: The WHQ proved to be a questionnaire easily translated into Portuguese and well-adjusted to Brazilian women. The internal consistency of the overall WHQ was excellent (Cronbach alpha =0.83; 95% CI: 0.71-0.91). Test-retest reliability was also excellent (intraclass correlation coefficient [ICC]=0.92; 95% IC: 0.86-0.96) and had good absolute agreement (0.84; 95% CI: 0.71-0.92). A satisfactory clinical validity was observed. The construct validity was corroborated by clear associations with others scales. A good index of responsiveness after the intervention was reached. CONCLUSIONS: The Portuguese version of the WHQ is of easy and fast administration and understanding. Its measuring properties were related, allowing its use in the evaluation of Brazilian climacteric women's quality of life for various purposes.

Pesticides and respiratory symptoms among farmers

OBJECTIVE: Despite the intensive use of pesticides in agriculture there are few studies assessing the risk of respiratory conditions from this exposure. The study aimed at quantifying the prevalence of respiratory symptoms among farmers and evaluating its relationship with occupational use of pesticides and the prevalence of respiratory symptoms. METHODS: A cross-sectional study was conducted among 1,379 farmers from two municipalities of Southern Brazil in 1996. Frequency and type of chemical exposure and pesticide poisoning were recorded for both sexes. All subjects aged 15 years or older with at least 15 weekly hours of agricultural activity were interviewed. An adapted questionnaire developed by the American Thoracic Society was used for the assessment of respiratory symptoms. Multivariate logistic regression analysis was carried out. RESULTS: More than half (55%) of interviewees were male. The prevalence of asthma symptoms was 12% and chronic respiratory disease symptoms was 22%. Higher odds ratios for both asthma (OR=1.51; 95% CI: 1.07-2.14) and chronic respiratory disease (OR=1.34; 95% CI 1.00-1.81) symptoms were found in women. Logistic regression analysis identified associations between many forms of exposure to pesticides and increased respiratory symptoms. Occurrence of pesticide poisoning was associated with higher prevalence of asthma symptoms (OR=1.54; 95% CI: 1.04-2.58) and chronic respiratory disease symptoms (OR=1.57; 95% CI: 1.08-2.28). CONCLUSIONS: In spite of causality limitations, the study results provide evidence that farming exposure to pesticides is associated with higher prevalence of respiratory symptoms, especially when the exposure is above two days per month.

Occupational exposure to particulate matter and respiratory symptoms in Portuguese swine barn workers

Certain environmental conditions in animal and plant production have been associated with increased frequency in respiratory illnesses, including asthma, chronic bronchitis, and hypersensitivity pneumonitis, in farmers occupationally exposed in swine production. The aim of this study was to characterize particulate matter (PM) contamination in seven Portuguese swine farms and determine the existence of clinical symptoms associated with asthma and other allergy diseases, utilizing the European Community Respiratory Health Survey questionnaire. Environmental assessments were performed with portable direct-reading equipment, and PM contamination including five different sizes (PM0.5, PM1.0, PM2.5, PM5.0, PM10) was determined. The distribution of particle size showed the same trend in all swine farms, with high concentrations of particles with PM5 and PM10. Results from the questionnaire indicated a trend such that subjects with diagnosis of asthma were exposed to higher concentrations of PM with larger size (PM2.5, PM5, and PM10) while subjects with sneezing, runny nose, or stuffy nose without a cold or flu were exposed to higher concentrations of PM with smaller size (PM0.5 and PM1). Data indicate that inhalation of PM in swine farm workers is associated with increased frequency of respiratory illnesses.

Factors associated with depression symptoms in high school students in São Paulo, Brazil

OBJECTIVE: To assess factors associated with depression symptoms in high school students. METHODS: A cross-sectional study involving high school students was conducted in the city of São Paulo, Brazil, 2001. A total of 724 students aged 14-18 years answered questionnaires on life and health conditions. Another questionnaire was applied to working (44.8%) and unemployed (22.9%) students to collect information on working conditions. Factors associated to depressive disorders were analyzed using multiple logistic regression controlled for occupational status. RESULTS: Overall prevalence rate of depression was 7.5%. Rates according to gender were 39 (10.3%) in females and 15 (4.3%) in males. The multiple logistic regression analysis showed that factors associated with depressive disorders were: poor self-perception of health (OR=5.78), being female (OR = 2.45), and alcohol consumption (OR=2.35). CONCLUSIONS: The study results showed that sociodemographic, lifestyle and health variables were associated with symptoms of depression in this population. These ndings suggest that it is important to have mental health professionals available in high schools for early detection of mental conditions and student counseling.

Depressive symptoms in institutionalized older adults

OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals.

Screening for depressive symptoms in older adults in the Family Health Strategy, Porto Alegre, Brazil

OBJECTIVE To analyze the prevalence of depression in older adults and associated factors. METHODS Cross-sectional study using a stratified random sample of 621 individuals aged ≥ 60 from 27 family health teams in Porto Alegre, RS, Southern Brazil, between 2010 and 2012. Community health agents measured depression using the 15-item Geriatric Depression Scale. Scores of ≥ 6 were considered as depression and between 11 and 15 as severe depression. Poisson regression was used to search for independent associations of sociodemographic and self-perceived health with both depression and its severity. RESULTS The prevalence of depression was 30.6% and was significantly higher in women (35.9% women versus 20.9% men, p < 0.001). The variables independently associated with depression were: female gender (PR = 1.4, 95%CI 1.1;1.8); low education, especially illiteracy (PR = 1.8, 95%CI 1.2;2 6); regular self-rated health (OR = 2.2, 95%CI 1.6;3.0); and poor/very poor self-rated health (PR = 4.0, 95%CI 2.9;5.5). Except for education, the strength of association of these factors increases significantly in severe depression. CONCLUSIONS A high prevalence of depression was observed in the evaluations conducted by community health agents, professionals who are not highly specialized. The findings identified using the 15-item Geriatric Depression Scale in this way are similar to those in the literature, with depression more associated with low education, female gender and worse self-rated health. From a primary health care strategic point of view, the findings become still more relevant, indicating that community health agents could play an important role in identifying depression in older adults.

Asthenopic symptoms and binocular vision of professional users of optical microscope

Desde 1935 que tem sido demonstrada a relação entre a execução de um trabalho de perto prolongado e o aparecimento de queixas visuais astenópicas. Anomalias da VB encontram-se significativamente aumentadas ao fim de um dia de trabalho com fixação de perto. Diminuição significativa da amplitude de acomodação e convergência depois de quatro dias a realizar uma atividade de perto. Objectivo geral: avaliar o estado da visão binocular dos profissionais de Anatomia Patológica utilizadores de microscópio ótico. Objectivos específicos: identificar as queixas astenópicas mais frequentes dos profissionais durante o trabalho com o microscópio ótico; comparar o estado da VB no início e no final de uma semana de trabalho; correlacionar o estado da VB com as queixas astenópicas sentidas pelos profissionais; correlacionar as queixas astenópicas com as horas e o número de anos de trabalho com o microscópio.

Validity of selected clinical signs and symptoms in diagnosis of Schistosoma mansoni infection

Sensitivity, specificity and positive predictive values of selected clinical signs and symptoms in the diagnosis of Schistosoma mansoni infection were evaluated in 403 individuals (69% of inhabitants over 1 year of age) in an endemic area in Brazil (Divino). Highest sensitivity (13%) was found for blood in stools. Specificity over 90% was found for blood in stools, palpable liver with normal consistency and palpable hardened liver at middle clavicular (MCL) or middle sternal lines (MSL). Hardened liver at MSL (83%) or MCL (75%), and blood in stools (78%) presented higher positive predictive values for S. mansoni infection, while palpable liver with normal consistency at MCL (45%) or MSL (48%) presented smaller values. Enlarged liver without specification of its consistency has been traditionally used as an indicator of the infection in areas where malaria or Kalazar are not endemic. Our results demonstrate that the probability that a person with blood in stools or hardened palpable liver is infected is higher than among those with palpable liver with normal consistency.

Relevant prevalence of Mycoplasma hominis and Ureaplasma urealyticum serogroups in HIV-1 infected men without urethritis symptoms

M. hominis and U. urealyticum are the better-known mycoplasma species pathogenic to the human genitourinary tract, causing mainly urethritis, bacterial vaginosis and pregnancy complications. In HIV-infected patients, the prevalence and role of these species is still not well known. The aim of this work was to determinate the prevalence of these species in this group of male patients (HIV group), in comparison to a group of men with clinical symptoms of urethritis (STD group). M. hominis was isolated from 7.5% patients (8/106) and U. urealyticum from 18.9% patients (20/106) from the HIV group, being among these 62.5% and 85% in significant concentrations, respectively. In the STD group these rates were 0.9% (1/110) for M. hominis and 13.6% (15/110) for U. urealyticum, being 100% and 93.3% in significant concentrations, respectively. We could demonstrate infection rates by these mycoplasma species in the HIV group as high as the one found in the STD one, what may indicate the occurrence of opportunistic infections in our population. This fact is discussed here because in immunosuppressed patients, specially M. hominis has been reported causing severe infections, even systemically.

Tradução com adaptação cultural para portugês e determinação da reprodutibilidade do questionnaire on respiratory symptoms in preschool children

RESUMO: Introdução: A asma brônquica é uma entidade frequente em idade pediátrica, apresentando uma grande heterogeneidade clínica e significativa morbilidade quando não controlada. A identificação de crianças sintomáticas pode atrasar ou até mesmo diminuir a ocorrência de algumas alterações estruturais. Reconhece-se a necessidade de questionários sobre sintomas respiratórios em língua portuguesa, devidamente validados, que tenham como população-alvo os grupos etários inferiores a 3 anos. Deste modo, será possível não só um conhecimento mais rigoroso da asma e da sibilância infantil mas também a uniformização de metodologias para o desenvolvimento de estratégias a nível nacional. Objetivos: Tradução com adaptação cultural para português e determinação da reprodutibilidade do Questionnaire on respiratory symptoms in preschool children de Strippoli e colaboradores. Material e métodos: A escolha do questionário obedeceu a vários critérios, entre os quais o grupo etário, o tipo e número de perguntas. O Questionnaire on respiratory symptoms in preschool children de Strippoli e colaboradores é um questionário de autopreenchimento, dirigido a crianças entre os 12 e os 24 meses de idade e destinado a estudos epidemiológicos ao nível da comunidade. Aborda aspetos referentes a sintomas respiratórios (sibilância, tosse crónica, sintomas das vias aéreas superiores), cuidados médicos, terapêutica, características ambientais, história familiar e situação social. Procedemos à sua tradução, com especial atenção para a adaptação do ponto de vista cultural e linguístico, utilizando o método da tradução / retroversão, amplamente utilizado e descrito na literatura internacional. Seguidamente determinámos a reprodutibilidade da versão final em língua portuguesa – Questionário de sintomas respiratórios em idade pré-escolar – utilizando o teste-reteste. Para tal, incluíram-se crianças entre os 12 e os 36 meses de idade recrutadas num Centro de Saúde e em creches de Lisboa. A distribuição dos questionários decorreu em duas fases: na primeira fase foram entregues pessoalmente nos locais de recrutamento e na segunda fase foram enviados por correio para os domicílios das crianças, respeitando-se um intervalo mínimo de 2 semanas entre ambos. Resultados: Na primeira fase foram distribuídos 180 questionários, com uma taxa de reposta de 41% (n=74). Na segunda fase enviaram-se para os respetivos domicílios 70 questionários,obtendo-se uma taxa de resposta de 66% (n=46). Para a análise de reprodutibilidade foram incluídos apenas os questionários preenchidos em ambos os momentos pelo mesmo indivíduo (mãe, pai ou representante legal) (n=41). A idade média das crianças foi, na primeira fase, de 22,5 meses e, na segunda fase, de 23,7 meses, com um predomínio do sexo feminino (F:M =1:0,6). A mediana do tempo decorrido entre os dois momentos de preenchimento dos questionários foi de 26 dias. Obtivemos valores de concordância globalmente bons a muito bons, à semelhança do sucedido no trabalho original. Conclusões: Procedemos à tradução e avaliação da reprodutibilidade do Questionnaire on respiratory symptoms in preschool children. Pretende-se que venha a ser uma ferramenta útil para estudos epidemiológicos e programas de rastreio na comunidade, contribuindo deste modo para uma otimização da abordagem da asma / sibilância infantil a nível nacional. -------------ABSTRACT: Background: Asthma is a very common feature in childhood, with important clinical heterogeneity and morbidity if not properly controlled. Identifying symptomatic children may delay or even reduce several structural changes. The development of questionnaires on respiratory symptoms in Portuguese for children under 3 years old will allow not only a more accurate knowledge of infantile asthma and recurrent wheezing but also the standardization of methodologies to develop nationwide strategies. Objectives: The aim of this study was to translate and adapt to the Portuguese culture and to determine the repeatability of the Questionnaire on respiratory symptoms in preschool children by Strippoli et al. Material and methods: The choice of the questionnaire took in consideration several criteria, among which the target age, the type and the number of questions. The Questionnaire on respiratory symptoms in preschool children by Strippoli et al is a parent-completed questionnaire for assessment of respiratory symptoms in 1 to 2-year-old children, developed for cross-sectional and longitudinal studies. It contains sections on respiratory symptoms (wheezing, chronic cough and upper airways symptoms), healthcare utilization, treatment, environmental exposure, family history and social situation. For the process of translation we used the method of translation and back-translation, with particular concern to cultural and linguistic adaptation. To assess the repeatability of the final Portuguese version - Questionário de sintomas respiratórios em idade pré-escolar - we used the test–retest analyses. The questionnaires were distributed to parents of children between 12 and 36 months old attending nurseries and a Primary Care Center of Lisbon. The distribution took place in two phases: the first questionnaires were delivered in person (phase one) and an identical questionnaire was posted to the families that participated in the first phase, 2 weeks after the first one was returned (phase two). Results: The response rates were 41% (180/74) in the first phase and 66% (70/46) in the second phase. For test–retest analyses, we included the 41 children with the same respondent (mother, father or legal representative) in both occasions. The median age of the children was 22,5 months at the first phase and 23,7 months at the second phase, with a predominance of girls (F:M = 1:0,6). The median time between the fillings of both questionnaires was 26 days. Globally, agreement values were good to excellent, similarly to the original work. Conclusion: In the present study we translated the Questionnaire on respiratory symptoms in preschool children and assessed its repeatability. Overall, we expect it to be a valuable tool for epidemiological studies and community-based screening programs, thus contributing to improve the management of infantile asthma / recurrent wheezing nationwide.

Unilateral Versus Bilateral Prostatic Arterial Embolization for Lower Urinary Tract Symptoms in Patients with Prostate Enlargement

PURPOSE: This study was designed to compare baseline data and clinical outcome between patients with prostate enlargement/benign prostatic hyperplasia (PE/BPH) who underwent unilateral and bilateral prostatic arterial embolization (PAE) for the relief of lower urinary tract symptoms (LUTS). METHODS: This single-center, ambispective cohort study compared 122 consecutive patients (mean age 66.7 years) with unilateral versus bilateral PAE from March 2009 to December 2011. Selective PAE was performed with 100- and 200-μm nonspherical polyvinyl alcohol (PVA) particles by a unilateral femoral approach. RESULTS: Bilateral PAE was performed in 103 (84.4 %) patients (group A). The remaining 19 (15.6 %) patients underwent unilateral PAE (group B). Mean follow-up time was 6.7 months in group A and 7.3 months in group B. Mean prostate volume, PSA, International prostate symptom score/quality of life (IPSS/QoL) and post-void residual volume (PVR) reduction, and peak flow rate (Qmax) improvement were 19.4 mL, 1.68 ng/mL, 11.8/2.0 points, 32.9 mL, and 3.9 mL/s in group A and 11.5 mL, 1.98 ng/mL, 8.9/1.4 points, 53.8 mL, and 4.58 mL/s in group B. Poor clinical outcome was observed in 24.3 % of patients from group A and 47.4 % from group B (p = 0.04). CONCLUSIONS: PAE is a safe and effective technique that can induce 48 % improvement in the IPSS score and a prostate volume reduction of 19 %, with good clinical outcome in up to 75 % of treated patients. Bilateral PAE seems to lead to better clinical results; however, up to 50 % of patients after unilateral PAE may have a good clinical outcome.
