Smoking, drinking and body weight after re-employment: does unemployment experience and compensation make a difference?

<p>Abstract</p> <p>Background</p> <p>The impact of unemployment on behaviours such as smoking, drinking and body weight has been extensively researched. However, little is known about the possible protective effects of social assistance programs on these behavioural changes. This study examines the impact of unemployment periods on smoking, drinking and body weight changes among re-employed individuals and investigates whether the receipt of unemployment benefits influences these behaviours.</p> <p>Methods</p> <p>This study used panel data provided by the Panel Study of Income Dynamics. Logistic regression models were used to analyze whether a period of unemployment in 2000 resulted in an increase in smoking and drinking or fluctuations in body weight among 2001 re-employed individuals in comparison with 1999 baseline levels. A total of 3,451 respondents who had been initially healthy and who had been continuously employed between 1998 and 1999 were included in the analysis.</p> <p>Results</p> <p>Compared to stably employed respondents, those who had experienced periods of unemployment in 2000 and did not receive unemployment benefits were more likely than continuously employed individuals to report an increase in alcohol consumption (OR 1.8, 95% CI 1.0–3.1) and a decrease in body weight (OR 1.7, 95% CI 1.1–2.8) when they were already re-employed in 2001.</p> <p>Conclusion</p> <p>Our findings suggest that the receipt of unemployment benefits confers a protective effect on health behavioural changes following periods of unemployment. These findings underscore the need to monitor the impact of unemployment assistance programs on health, particularly in light of the rapidly changing structure of employment and unemployment benefits.</p

Safety and immunomodulatory effects of three probiotic strains isolated from the feces of breast-fed infants in healthy adults: SETOPROB study

We previously described the isolation and characterization of three probiotic strains from the feces of exclusively breast-fed newborn infants: Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036. These strains were shown to adhere to intestinal mucus in vitro, to be sensitive to antibiotics and to resist biliary salts and low pH. In the present study, a multicenter, randomized, double-blind, placebo-controlled trial with 100 healthy volunteers in three Spanish cities was carried out to evaluate the tolerance, safety, gut colonization and immunomodulatory effects of these three probiotics. Volunteers underwent a 15-day washout period, after which they were randomly divided into 5 groups that received daily a placebo, a capsule containing one of the 3 strains or a capsule containing a mixture of two strains for 30 days. The intervention was followed by another 15-day washout period. Patients did not consume fermented milk for the entire duration of the study. Gastrointestinal symptoms, defecation frequency and stool consistency were not altered by probiotic intake. No relevant changes in blood and serum, as well as no adverse events occurred during or after treatment. Probiotic administration slightly modified bacterial populations in the volunteers’ feces. Intestinal persistence occurred in volunteers who received L. rhamnosus CNCM I-4036. Administration of B. breve CNCM I-4035 resulted in a significant increase in fecal secretory IgA content. IL-4 and IL-10 increased, whereas IL-12 decreased in the serum of volunteers treated with any of the three strains. These results demonstrate that the consumption of these three bacterial strains was safe and exerted varying degrees of immunomodulatory effects.Part of the research currently in progress in the authors' laboratory is funded by the company Hero Spain, S.

Amphibian declines in the twenty-first century: why we need assisted reproductive technologies

Each amphibian species is evolutionarily distinct, having developed highly specialized and diverse reproductive strategies in both terrestrial and aquatic environments. These unique reproductive patterns and mechanisms, key to species propagation, have only been explored in a limited number of laboratory models. Although the development of applied reproductive technologies for amphibians has proven useful for a few threatened species, the real benefit of this technology has been new insights into the reproductive adaptations, behavior, endocrinology, and physiological mechanisms that have evolved over millions of years. As the basic fundamental database on amphibian reproductive physiology has grown, so has the applied benefit for species conservation. In particular, technologies such as non-invasive fecal and urinary hormone assays, hormone treatments for induced breeding or gamete collection, in vitro fertilization, and the ability to establish genome resource banks have all played important roles in monitoring or managing small populations of captive species. Amphibians have the ability to produce a large excess of germplasm (up to 10,000 ovulated eggs in a single reproductive event) that if not collected and preserved, would represent a wasted valuable resource. We discuss the current state of knowledge in assisted reproductive technologies for amphibians and why their extinction crisis means these available tools can no longer be implemented as small-scale, last-ditch efforts. The reproductive technologies must be established early as a key component of large-scale species recovery

Influência de diferentes concentrações de flúor na água em indicadores epidemiológicos de saúde/doença bucal Influence of different concentrations of fluoride in the water on epidemiologic indicators of oral health/disease

O objetivo deste estudo foi avaliar o acesso a fontes de fluoreto e as condições de saúde bucal de 237 escolares de nove a dezesseis anos, de três localidades com diferentes concentrações de fluoreto na água. O teor de flúor na água de cada região foi analisado pela técnica do eletrodo seletivo para o íon flúor e a foi avaliada prevalência de cárie e fluorose, respectivamente, pelo índice CPOD e TSIF, apresentando diferença estatisticamente significante (ANOVA; p < 0,05) nas três localidades: área sem fluoretação artificial (CPOD 5,32 ± 3,49) e 16% de fluorose; área com fluoretação artificial de 0,8 ppmF (CPOD 1,88 ± 2,22) e 94% de fluorose; área com fluoretação natural de 2,54 ppmF (CPOD 3,96 ± 2,38) e 100% de fluorose. Os achados sugerem que os indicadores epidemiológicos de saúde/doença bucal estudados são influenciados pela presença de fluoreto na água de consumo e que a supervisão e a orientação são fundamentais na correta utilização dos compostos fluoretados, aproveitando-se o máximo benefício no controle da cárie dentária com o mínimo risco de ocorrência de fluorose.<br>The scope of this study was to evaluate access to fluoride sources and oral health hygiene of 237 schoolchildren aged nine to sixteen, from three locations with different fluoride concentrations in the water. The fluoride level in the water of each area was analyzed by the selective electrode technique for the fluoride ion and the prevalence of dental caries and fluorosis were evaluated, respectively, by the DMFT and TSIF index, revealing a statistically significant difference (ANOVA; p <0,05) in the three locations: area without artificial fluoridation (DMTF 5.32 ± 3.49) and 16% of dental fluorosis; area with artificial fluoridation of 0.8 ppmF (DMTF 1.88 ± 2.22) and 94% of dental fluorosis; area with natural fluoridation of 2.54 ppmF (DMTF 3.96 ± 2.38) and 100% of dental fluorosis. The findings suggest that the epidemiologic indicators of oral health/disease are influenced by the presence of fluoride in the water supply and that supervision and orientation are fundamental in the correct use of fluoridated compositions, taking advantage of the maximum benefit in the control of dental caries with minimum risk of the occurrence of dental fluorosis

Triagem de hemoglobinopatias em doadores de sangue de Caxias do Sul, Rio Grande do Sul, Brasil: prevalência em área de colonização italiana Screening for hemoglobinopathies in blood donors from Caxias do Sul, Rio Grande do Sul, Brazil: prevalence in an Italian colony

A alta prevalência de beta-talassemia em italianos e a participação dos mesmos na formação étnica da cidade de Caxias do Sul e arredores, Rio Grande do Sul, Brasil, conduziram-nos à investigação de hemoglobinopatias em uma amostra de 608 doadores de sangue do Hemocentro Regional de Caxias do Sul. Apesar da influência étnica, encontramos 1,81% de hemoglobinas anormais (0,16% Hb AC, 0,99%, Hb AS e 0,66% Hb AH), um padrão similar com o estudo do interior do Estado do Rio Grande do Sul para alterações qualitativas. Para as talassemias, as técnicas mais comuns, cruzadas com seqüenciamento de DNA, em nossas mãos, não foram capazes de esclarecer anormalidades quantitativas da hemoglobina. Esse resultado pode ser atribuído a alterações genéticas ainda não conhecidas, a limitações técnicas ou, mais simplesmente, à miscigenação.<br>The high prevalence of beta thalassemia among Italians and their participation in the ethnic formation of Caxias do Sul, Rio Grande do Sul State, Brazil, and neighboring cities prompted us to investigate hemoglobinopathies in 608 blood donors at the Caxias do Sul Regional Blood Center. Despite the ethnic influence, abnormal hemoglobin levels were found in only 1.81% of the donors (0.16% Hb AC, 0.99% Hb AS, and 0.66% Hb AH), similar to the levels observed in a study on qualitative disorders conducted in the rural area of Rio Grande do Sul. In our setting, the most commonly used screening tests for thalassemia, combined with DNA sequencing, were unable to detect quantitative hemoglobin synthesis disorders. This may be attributable to still-unknown genetic disorders, technical limitations, or simply to miscegenation
