Obesity is a serious health issue and predisposes individuals to an increased risk of morbidity and mortality. Its prevalence in children has increased worldwide.
To demonstrate the feasibility and effectiveness of a school-based management program based on healthy lifestyle promotion for obese and overweight adolescents in Sousse, Tunisia.
We conducted a quasi-experimental study among overweight and obese school children enrolled in 7th and 8th grades in Sousse, Tunisia with two groups, intervention and control. The 1-year intervention was based on promoting healthy eating and physical activity through a collective intervention for all recruited children and an individual intervention only for obese children who require intensive managing. Data collection was done before, at the end and at a 4-month follow up of the intervention, both in intervention and control groups.
The body mass index Z score decreased significantly from pre-intervention to post-intervention (1.89±0.57 to 1.76±0.63, p<0.001) and from post-intervention to the follow-up (1.76±0.63 to 1.55±0.68, p<0.001) in the intervention group. In the control group, it decreased significantly from pre-intervention to post-intervention but not significantly from post-intervention to follow-up assessment. Calorie intake decreased significantly both in intervention and control groups.
This project began with introducing a new culture of health management in schools on one side and with increasing awareness of the importance of obesity prevention and treatment. The support of authorities for this type of action is very important to guarantee its sustainability.

This study aimed to (1) examine Ugandan adolescents' baseline STI and contraceptive knowledge; (2) determine whether this knowledge varies by demographic factors, prior sexual experience or school grade; and (3) evaluate the effectiveness of an educational program to increase and retain STI and contraceptive knowledge among Ugandan adolescents. This study surveyed 129 adolescents (ages 15-19) regarding knowledge of STIs and contraceptive methods at schools and community non-governmental organizations at three time points. Findings demonstrated that at baseline the mean test scores for contraceptive knowledge and STI knowledge were 44% and 72%, respectively. Participants in higher secondary school grade-levels had greater odds of having prior STI knowledge (OR=19.6, 95% CI 2.0-187.6); participants who had previously engaged in sex had greater odds of having prior contraceptive knowledge (OR=4.62, 95% CI 1.45-14.72). A higher grade level was not associated with better knowledge of contraception; and being sexually active was not associated with better knowledge of STI information. Participants' knowledge of STIs and contraceptives improved after the education session (p less then 0.001), and knowledge was retained 3-weeks later (p less then 0.001). Findings suggest that Ugandan adolescents do not have adequate education regarding contraceptive methods and that implementation of reproductive health modules by an outside party can be effective in improving knowledge.
Tobacco use, which begins in adolescence and childhood and continues in later life, is the major avoidable risk for non-communicable diseases and death in the world. Self-reports have frequently been used to estimate smoking prevalence and health consequences. This study explores the validity of self-reports of smoking behavior among schoolchildren in Tunisia.
This study was conducted in March 2014 among a sample of 147 schoolchildren randomly selected. Data concerning the smoking habit were collected by a questionnaire designed for the purposes of this work. Then, exhaled CO, a biochemical marker of smoke exposure, was measured using piCO+ Smokerlyzer® breath CO monitor among participants. Sensitivity and specificity of self-reports were calculated.
The prevalence of reported smoking was 9.5% with 16.7% and 1.7% respectively among boys and girls. Their mean age was 14.5±1.28 years old. When considering 4 ppm as the cut-off level of breath CO, sensitivity and specificity of self-reports were 100% and 93.7%, respectively. But at a breath CO cut-off of 3 ppm, self-reporting was 62.5% sensitive and 93.5% specific.
According to our findings, we suggest that self-reports can be considered as a good tool to be used with a reasonable confidence to assess the smoking status.

Microbial invasion of the fetus due to intra-amniotic infection can lead to a systemic inflammatory response characterized by elevated concentrations of cytokines in the umbilical cord plasma/serum. Clinical chorioamnionitis represents the maternal syndrome often associated with intra-amniotic infection, although other causes of this syndrome have been recently described. The objective of this study was to characterize the umbilical cord plasma cytokine profile in neonates born to mothers with clinical chorioamnionitis at term, according to the presence or absence of bacteria and/or intra-amniotic inflammation.
A cross-sectional study was conducted, including patients with clinical chorioamnionitis at term (n=38; cases) and those with spontaneous term labor without clinical chorioamnionitis (n=77; controls). Women with clinical chorioamnionitis were classified according to the results of amniotic fluid culture, broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry (Poncentrations of umbilical cord plasma cytokines than those born to mothers without clinical chorioamnionitis. Even neonates exposed to clinical chorioamnionitis but not to intra-amniotic inflammation had elevated concentrations of multiple cytokines, suggesting that intrapartum fever alters the fetal immune response.

Seeds were incubated in 0, 50, 100, 150, 200, 250 and 300 mM NaCl to determine the salt tolerance of the Lycium ruthenicum Murr seedlings and from the results, the critical and ultimate salt concentrations were chosen for the next experiment. Subsequently, two treatments (seeds soaked in Ge and Ge added to salt) with four concentrations of GeO2 (0, 5, 10 and 20 μM) were used with the critical (150 mM) and ultimate salt concentrations (250 mM). The results demonstrated that salt alone inhibited seed germination significantly (≥150 mM) and reduced seedling growth (≥200 mM). The addition of exogenous Ge to the salt solution, as well as soaking the seeds in Ge, attenuated the salt stress effects in a manner dependent on the dose of Ge, as indicated by the increased percentage of seeds that germinated and improved seedling growth. The addition of Ge also showed a significant reversal of salt stress on the activities of antioxidant enzymes, with a decrease in SOD and POD activity, but an increase in CAT activity with 150 mM NaCl, and enhancement of SOD, POD and CAT with 250 mM NaCl. Correspondingly, the level of malondialdehyde was decreased significantly by each Ge treatment under salt stress. Further, for L. ruthenicum, adding 10 Ge and seeds soaked in 5 Ge were the most effective treatments. To our knowledge, this is the first report to show the protective effects of exogenous Ge against salt-induced oxidative damage in L. ruthenicum seed germination and seedling growth. Thus, L. ruthenicum can be used in areas with salty soil and Ge can promote the plants' salt tolerance.Lysobacter enzymogenes strain C3 is a gliding bacterium which produces the antifungal secondary metabolite heat-stable antifungal factor (HSAF) and type IV pilus (T4P) as important mechanisms in biological control activity against fungal pathogens. To date, the regulators that control HSAF biosynthesis and T4P-dependent twitching motility in L. enzymogenes are poorly explored. In the present study, we addressed the role of pilG in the regulation of these two traits in L. enzymogenes. PilG of L. enzymogenes was found to be a response regulator, commonly known as a component of a two-component transduction system. Mutation of pilG in strain C3 abolished its ability to display spreading colony phenotype and cell movement at the colony margin, which is indicative of twitching motility; hence, PilG positively regulates twitching motility in L. enzymogenes. Mutation of pilG also enhanced HSAF production and the transcription of its key biosynthetic gene hsaf pks/nrps, suggesting that PilG plays a negative regulatory role in HSAF biosynthesis. This finding represents the first demonstration of the regulator PilG having a role in secondary metabolite biosynthesis in bacteria. Collectively, our results suggest that key ecological functions (HSAF production and twitching motility) in L. enzymogenes strain C3 are regulated in opposite directions by the same regulatory protein, PilG.
Functional brain networks of human have been revealed to have small-world properties by both analyzing electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) time series.
In our study, by using graph theoretical analysis, we attempted to investigate the changes of paralimbic-limbic cortex between wake and sleep states. Ten healthy young people were recruited to our experiment. Data from 2 subjects were excluded for the reason that they had not fallen asleep during the experiment. GX15-070 mw For each subject, blood oxygen level dependency (BOLD) images were acquired to analyze brain network, and peripheral pulse signals were obtained continuously to identify if the subject was in sleep periods. Results of fMRI showed that brain networks exhibited stronger small-world characteristics during sleep state as compared to wake state, which was in consistent with previous studies using EEG synchronization. Moreover, we observed that compared with wake state, paralimbic-limbic cortex had less connectivity with neocortical system and centrencephalic structure in sleep.
