    There has been a move in recent years towards the greater inclusion of social and ethical issues within science courses. This paper examines a new context-based course for 16 18 year-olds (Salters-Nuffield Advanced Biology) who are studying biology in England and Wales. The course is taught through contexts and has an emphasis on social issues and the development of ethical reasoning. Examination of a sample of reports written by students in 2005 as part of the course’s summative assessment shows that utilitarian ethical reasoning is used widely and that the other ethical frameworks to which students are introduced in the course—rights and duties, autonomy and virtue ethics—are used substantially less often. In addition, students mostly argue anthropocentrically though many of them argue ecocentrically and/or biocentrically too.

  5. The national vocational education plan for unqualified young people (16?18 years old): The French experience (1982?1984)

    1986-12-01

    In 1982, the French Government instituted a new National Vocational Education Plan (NVEP) to combat the nationwide problem of students leaving the school system prior to receiving adequate vocational preparation. This plan affects 100,000 young people between the ages of 16 and 18 years. The NVEP gave to each Regional Government the opportunity to create its own programmes and curricula; it renewed counselling and individual assessment facilities; it established new tracks within the education system; it also established co-operative education (linking education to the world of work). Concurrently, an Assessment and Observation System was created. During the first assessment year (1982-1983), information was gathered about existing local educational resources, counselling facilities, characteristics of the 16 to 18 year-old population, functioning of the educational tracks and co-operative education system. During the second year (1983-1984), the assessment provided quantitative statistical results. The most striking result concerns the configurations of educational and employment experiences which seemed to determine the ability of students to find employment. Students with a background of `job intensive experiences' were more successful in finding subsequent employment than those without. Students with `education intensive experiences' entered an educational programme because they were unable to find a first job. While the benefits of the NVEP were not immediately apparent, it nevertheless became evident that at this level of training, education was not necessarily the royal road to employment. However, employment criteria cannot be the only way to assess a vocational education system.

  6. Intranasal versus subcutaneous rubella vaccination in schoolgirls.

    Midulla, M; Assensio, A M; Balducci, L; Vanni, O; Msstropasqua, S

    1976-01-01

    In this study a venous blood specimen was drawn and, at the same time, rubella vaccine was given to 1906 schoolgirls mostly in the pre-pubertal age. To assess the pre-vaccination immune status and the effect of the vaccine, a second blood sample was taken 6 weeks later and tested for rubella HAI antibody simultaneously with the first one. RA 27/3 rubella vaccine administered by intranasal route to 81 girls produced a 100% seroconversion rate and the same vaccine strain, given by subcutaneous route to 460 girls, produced a 94.73% seroconversion rate. Among the 1, 365 schoolgirls who received subcutaneous Cendehill vaccine, the seroconversion rate was 86.68%. Side effects were mild and transient and occurred, as headache, most frequently among the girls who received RA 27/3 vaccine by intranasal route.

  7. Unusual formaldehyde-induced hypersensitivity in two schoolgirls

    1990-01-01

    Two schoolgirls developed a syndrome resembling Henoch-Schonlein purpura while attending a recently opened school insulated with urea-formaldehyde foam (UFFI). Skin rashes and swellings were accompanied by bizarre, blue-green discoloration of the skin. Subsequent investigations by county, state and federal authorities, and low measured concentrations of formaldehyde, prompted initial conclusions that in-school formaldehyde exposures were not responsible for the girls' problems. Subsequent controlled exposures to UFFI and formaldehyde while in hospital elicited the whole cascade of symptoms. The chronology of the onset and amplification of systems make it probable that the formaldehyde exposures precipitating the girls' hypersensitivity, occurred in the school. 3 refs.

    The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10-16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants' preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed. PMID:19910269

    2005-11-01

    Learning about menstrual hygiene is a vital aspect of health education for adolescent girls. This study among 664 schoolgirls aged 14-18 in Mansoura, Egypt, asked about type of sanitary protection used, frequency of changing pads or cloths, means of disposal and bathing during menstruation. Girls were selected by cluster sampling technique in public secondary schools in urban and rural areas. Data were collected through an anonymous, self-administered, open-ended questionnaire during class time. The significant predictors of use of sanitary pads were availability of mass media at home, high and middle social class and urban residence. Use of sanitary pads may be increasing, but not among girls from rural and poor families, and other aspects of personal hygiene were generally found to be poor, such as not changing pads regularly or at night, and not bathing during menstruation. Lack of privacy was an important problem. Mass media were the main source of information about menstrual hygiene, followed by mothers, but a large majority of girls said they needed more information. Instruction in menstrual hygiene should be linked to an expanded programme of health education in schools. A supportive environment for menstrual hygiene has to be provided both at home and in school and sanitary pads made more affordable.

    Reported data on age at menarche in a sample of Biscayan schoolgirls are compared with data from several Spanish populations. Though the mean age falls in the range of variation of the Spanish means, the analysis of variance shows significant differences among the series. With regard to the possible secular trend of this event in the Biscay province, both a stability of menarcheal age and a diminution of the process of variability are observed.

    Adolescence is a vulnerable period for the development of mental health problems. The DISCOVER intervention aims to provide accessible, acceptable and cost-effective psychological support for stressed adolescents in inner-city secondary schools. The intervention uses age-appropriate cognitive-behavioural therapy (CBT) methods and materials, delivered in an interactive 1-day workshop with additional telephone support. An open-access entry route allows students to self-refer. This protocol describes a feasibility cluster randomised controlled trial (RCT) comparing DISCOVER with a waitlist control condition. The study will run across 10 clusters (secondary schools) in the inner London Boroughs of Southwark and Lambeth. Participants are students aged over 16years who are seeking help with anxiety and/or depressive symptoms. Key feasibility parameters relate to the proportion of students willing to participate in the research following publicity events; the proportion of students who complete the intervention; and response rates for outcome measures. Outcome variance estimates and intra-cluster correlations will be obtained for future power calculations. Qualitative methods will be used to explore the acceptability of the intervention and research procedures for students and school staff. The feasibility of an economic evaluation will also be examined. The results will (i) determine the appropriateness of proceeding to a definitive full-scale trial; and (ii) inform the development of an optimised version of the DISCOVER intervention that can be tested within feasible parameters.

    1998-05-01

    Despite increasing trends in the prevalence of overweight and obesity, fatness phobia is common during female adolescence. This study has demonstrated a high level of dissatisfaction with body weight in a sample of Dublin schoolgirls aged 15 y. Of 420 subjects, 59% reported that they wanted to be slimmer and 68% had previously tried to lose weight. Contrary to expectations, overweight girls were not found to hold the monopoly on such dissatisfactions. Normal weight and even underweight girls also expressed a desire to be thinner and reported using unhealthy weight control practices including random avoidance of staple foods, fasting, smoking and purging, in their pursuit of the 'perfect' female figure. Obesity prevention programmes which target adolescent girls 'at risk' of overweight and obesity, must take cognizance of their profound fear of fatness, otherwise the use of harmful slimming strategies may be further increased as teenage girls frantically try to lose weight and to avoid the stigma associated with female fatness.

    Tammet, H.; Mirme, A.; Tamm, E.

    The electrical aerosol spectrometer (EAS) of the parallel measuring principle at Tartu University is an efficient instrument for rapid measurement of the unstable size spectrum of aerosol particles. The measuring range from 10 nm to 10 μm is achieved by simultaneously using a pair of differential mobility analyzers with two different particle chargers. The particle spectrum is calculated and measurement errors are estimated in real time by using a least-squares method. Experimental calibration ensures reliability of measurement. The instrument is well suited for continuous monitoring of atmospheric aerosol.

    The article describes two Estonian anthropometric cross-sectional studies of 1549 ordinary schoolgirls (aged 7-18) and 46 girls, who regularly practised volleyball (aged 13-16). Data are presented on 22 basic anthropometric measurements and 6 body composition characteristics (body mass index, mean skinfold, body density, relative mass of fat by Siri, absolute mass and relative mass of subcutaneous adipose tissue). All anthropometric variables were classified into five height-weight SD classes. Schoolgirls were divided into six age groups (7-8, 9-10, 11-12, 13-14, 15-16, 17-18). Volleyballers were observed as one group as their age in SD classes did not differ significantly. The classification consisted of five categories: three height-weight concordant categories: I--small (small height, small weight), II--medium (medium height, medium weight), III large--(big height, big weight) and two height/weight discordant categories: IV--so-called pyknomorphs, V--so-called leptomorphs. To assess the differences between classes the Scheffé-test was used (alpha = 0.05). It proved likewise possible to comparatively systematize length, breadth and depth measurements, circumferences and body composition characteristics in all six age groups (7-18 years) of ordinary schoolgirls and in 13-16-year-old volleyballers as in their case the average age did not differ significantly between the classes.

    The balance function of children is known to be affected by carriage of a school backpack. Children with adolescent idiopathic scoliosis (AIS) tend to show poorer balance performance, and are typically treated by bracing, which further affects balance. The objective of this study is to examine the combined effects of school backpack carriage and bracing on girls with AIS. A force platform was used to record center of pressure (COP) motion in 20 schoolgirls undergoing thoraco-lumbar-sacral orthosis (TLSO brace) treatment for AIS. COP data were recorded with and without brace while carrying a backpack loaded at 0, 7.5, 10, 12.5 and 15% of the participant’s bodyweight (BW). Ten participants stood on a solid base and ten stood on a foam base, while all participants kept their eyes closed throughout. Sway parameters were analyzed by repeated measures ANOVA. No effect of bracing was found for the participants standing on the solid base, but wearing the brace significantly increased the sway area, displacement and medio-lateral amplitude in the participants standing on the foam base. The medio-lateral sway amplitude of participants standing on the solid base significantly increased with backpack load, whereas significant increases in antero-posterior sway amplitude, sway path length, sway area per second and short term diffusion coefficient were found in participants standing on the foam base. The poorer balance performance exhibited by participants with AIS when visual and somatosensory input is challenged appears to be exacerbated by wearing a TLSO brace, but no interactive effect between bracing and backpack loading was found.

    1975-12-01

    A total of 1525 schoolgirls aged 13 years from 21 schools in the County Borough of Dudley, were bled for titration of rubella haemagglutinating inhibiting antibody and then were immediately vaccinated with either Wistar RA 27/3 or Cendehill strain live attenuated. Both vaccines were administered subcutaneously by syringe and needle but the Wistar RA 27/3 vaccine was also given by multiple injection apparatus. Significnatly higher conversion rates and geometric mean haemagglutinating inhibiting antibody titres were obtained in girls initially seronegative given the Wister RA 27/3 than in those given the Cendehill vaccine, regardless of the method of vaccination. The RA 27/3 strain was associated with a small but significantly greater incidence of local pain immediately on injection. With this exception, differences in the occurrence of reactions were not found between vaccines, between those initially susceptible and immune or with the level of antibody response.

    The aim of the present study was to assess the prevalence of deficiency of folate and vitamin B12 and, simultaneously, the nutrient intake adequacy of folate, vitamin B12, iron, vitamin A, vitamin C, vitamin B6 and calcium in 391 adolescent anaemic (Hb<120 g/l) schoolgirls living in the delta region of Myanmar (Burma). Dietary intakes were assessed using a 3 d estimated food record. The distribution of observed intakes calculated from the food records were adjusted for usual intakes, and the prevalence of inadequacy was estimated using the estimated average requirement cut-point method. Median (first, third quartile) serum folate and vitamin B12 concentrations were 6·5 (4·6, 8·5) nmol/l and 612·8 (443·2, 795·2) pmol/l, respectively. The prevalence of folate deficiency defined as <6·8 nmol/l was 54 %; however, vitamin B12 deficiency defined as <148 pmol/l was negligible (<1 %). The prevalence of inadequate intake of folate was high (100 %) as was the prevalence of inadequate intakes of vitamin A, vitamin C, vitamin B6 and calcium, ranging from 60 to 100 %. Red meat or poultry was rarely consumed, but fish was consumed on a daily basis. Green leafy vegetables were also consumed frequently but consumption of dairy products was uncommon. Folate deficiency was high, and the prevalence of inadequate intake of folate among other key micronutrients was relatively common in this sample of anaemic adolescent schoolgirls. Appropriate strategies such as food fortification and dietary diversification are needed to improve the micronutrient status of these young women to ensure optimal health and future reproductive success.

    In the year 1999, a new and modern building Biomedicum was finished addressed to preclinic subjects of the Medical Faculty of the University of Tartu; the institutions of anatomy as well as pathological anatomy and forensic medicine moved there. However; no place was planned to exhibit the collections of specimens. Many of the specimens which had so far only been used for learning purposes found their place in the Old Anatomical Theatre, in the hope that this could be transformed as a museum. The medical collections of the Medical Faculty were opened up for a broader audience in October 2005. With the support of the national programme "The collections of humanities and natural sciences", the medical study specimens, models, moulages, and literature related to them in danger of being destroyed were collected from several subdivisions and buildings of the Medical Faculty. In 2012, the medical exhibition moved to the premises of Science Centre AHHAA and in the same time a specifc educational study began to be developed.

    Introduction An increasing number of studies have found that girls in low-income settings miss or struggle at school during menstruation if they are unable to manage their menstrual hygiene effectively. This study explores the menstrual hygiene practices and knowledge of girls at rural government primary schools in the Rukungiri district in Uganda and assesses the extent to which poor menstrual hygiene management (MHM) affects their education. Methods A self-administered questionnaire was completed by schoolgirls in six government-run primary schools in the Rukungiri district. Focus groups were held with girls from each school and semi-structured interviews were conducted with headteachers and female teachers from the participating schools. A toilet assessment was also conducted in each school. Results One hundred and forty schoolgirls completed the questionnaire. The girls reported a lack of access to adequate resources, facilities and accurate information to manage their menstrual hygiene effectively at school. They reported that, as a result, during menstruation they often struggle at school or miss school. Eighty-six girls (61.7%) reported missing school each month for menstrual-related reasons (mean 1.64, range 0-10, SD. 1.84). Conclusion It is common for girls who attend government-run primary schools in the Rukungiri district to miss school or struggle in lessons during menstruation because they do not have access to the resources, facilities, or information they need to manage for effective MHM. This is likely to have detrimental effects on their education and future prospects. A large-scale study is needed to explore the extent of this issue. PMID:25852796

    The aim of this article was to give an historical overview of pharmacy education in Estonia and the social profile of pharmacy students of the University of Tartu (previously Dorpat and Jurjew) during the period 1802-2010. In addition, separate data is presented about female students and students of Estonian ethnicity. During the period observed, 6736 students studied pharmacy in the University of Tartu, of whom 4184 graduated in the specialty. The largest proportional representation by place of birth was Tartu and the Tartu region (13.5%). 42% of the students were 21-25 years old. The majority (96.84%) of the students were Estonians. At the end of the 19th century, russification of the university resulted in Russian being made the official language of instruction, with a concomitant decrease of ethnically German and an increase in ethnically Estonian students. Changes in admission policies have led to an increased number of Russian students among graduates since 2004. 2319 of the total 6736 students were female. During the period 1926-1940, women achieved the majority among graduates and they represent the majority up to the present day. PMID:22888526

    Background Keeping girls in school offers them protection against early marriage, teen pregnancy, and sexual harms, and enhances social and economic equity. Studies report menstruation exacerbates school-drop out and poor attendance, although evidence is sparse. This study qualitatively examines the menstrual experiences of young adolescent schoolgirls. Methods and Findings The study was conducted in Siaya County in rural western Kenya. A sample of 120 girls aged 14–16 years took part in 11 focus group discussions, which were analysed thematically. The data gathered were supplemented by information from six FGDs with parents and community members. Emergent themes were: lack of preparation for menarche; maturation and sexual vulnerability; menstruation as an illness; secrecy, fear and shame of leaking; coping with inadequate alternatives; paying for pads with sex; and problems with menstrual hygiene. Girls were unprepared and demonstrated poor reproductive knowledge, but devised practical methods to cope with menstrual difficulties, often alone. Parental and school support of menstrual needs is limited, and information sparse or inaccurate. Girls’ physical changes prompt boys and adults to target and brand girls as ripe for sexual activity including coercion and marriage. Girls admitted ‘others’ rather than themselves were absent from school during menstruation, due to physical symptoms or inadequate sanitary protection. They described difficulties engaging in class, due to fear of smelling and leakage, and subsequent teasing. Sanitary pads were valued but resource and time constraints result in prolonged use causing chafing. Improvised alternatives, including rags and grass, were prone to leak, caused soreness, and were perceived as harmful. Girls reported ‘other girls’ but not themselves participated in transactional sex to buy pads, and received pads from boyfriends. Conclusions In the absence of parental and school support, girls cope, sometimes

    Background In South Africa the teenage fertility rate is high. About 42% of women have their sexual debut by 18 years of age and 5% by 15. These young women are also at risk of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) infection. Despite widespread availability of contraception, 18% of sexually active teenagers do not use any. Previous research on the knowledge of, attitudes to and practices of contraception by teenagers has focused on older adolescents. Objectives This study explored knowledge, attitudes and practices about contraception amongst 12–14 year old unmarried schoolgirls with a view to inform planning of programmes to assist in reducing teenage pregnancies. Methods A qualitative study design with purposive sampling was used to select participants from two government-run schools in King Sabata Dalindyebo Municipality. In-depth and focus group interviews were conducted after obtaining written consent from parents and assent from participants. Interviews were audiotaped, transcribed verbatim, translated and analysed thematically. Findings Participants reported that young adolescents were sexually active, which included high-risk sexual behaviour such as multiple partners and casual and transactional sex. Knowledge about contraceptives varied widely. Condoms were the most preferred method of contraception, but it is unknown whether they ever used condoms as they professed to talk about the behaviour of others rather than themselves. Injectable contraceptives were believed to have long-term negative effects. Common sources of contraceptive information were friends or peers, school curriculum and to a lesser extent family members. Conclusions Findings of the study suggest that young adolescents are sexually active and have inadequate knowledge and misconceptions about contraception. These findings should inform educational programmes about risks of early sexual activity and about contraception.

    The Estonian Biobank cohort is a volunteer-based sample of the Estonian resident adult population (aged ≥18 years). The current number of participants-close to 52000--represents a large proportion, 5%, of the Estonian adult population, making it ideally suited to population-based studies. General practitioners (GPs) and medical personnel in the special recruitment offices have recruited participants throughout the country. At baseline, the GPs performed a standardized health examination of the participants, who also donated blood samples for DNA, white blood cells and plasma tests and filled out a 16-module questionnaire on health-related topics such as lifestyle, diet and clinical diagnoses described in WHO ICD-10. A significant part of the cohort has whole genome sequencing (100), genome-wide single nucleotide polymorphism (SNP) array data (20 000) and/or NMR metabolome data (11 000) available (http://www.geenivaramu.ee/for-scientists/data-release/). The data are continuously updated through periodical linking to national electronic databases and registries. A part of the cohort has been re-contacted for follow-up purposes and resampling, and targeted invitations are possible for specific purposes, for example people with a specific diagnosis. The Estonian Genome Center of the University of Tartu is actively collaborating with many universities, research institutes and consortia and encourages fellow scientists worldwide to co-initiate new academic or industrial joint projects with us.

    During 30 years, the professor of pharmacy Georg Dragendorff (1836-1898), who had been invited from Germany, supervised 90 theses of Master of Pharmacy and 87 theses of Doctor of Medicine in Tartu/Dorpat. The present article discusses the authors of these theses, Dragendorff and his co-operation with other university lecturers, the structure of the theses and the regulations of the thesis defence. Analysis of the contents of the theses revealed extensive contacts of the pharmacy of the time with different fields of science. Dragendorff as the supervisor of these theses contributed much to the training of physicians. PMID:15918592

    Evidence from a number of historical studies has demonstrated a strong impact of the provision of clean water on mortality risks, while no clear effect has been reported in others. We investigated the relationship between water supply, sanitation, and infant survival in Tartu, a university town in Estonia, 1897-1900. Based on data from parish registers, which were linked to the first census of the Russian Empire, the analysis reveals a clear disadvantage for infants in households using surface water, compared with families that acquired water from groundwater or artesian wells. The impact is stronger in the later stages of infancy. Competing-risk analysis shows that the effect is more pronounced for deaths caused by diseases of the digestive system. Our findings suggest that it may have been possible to improve the water supply, and consequently reduce infant mortality, before the introduction of piped water and sewage systems. PMID:27207615

    The annual international conference Functional Materials and Nanotechnologies (FM&NT) was started in 2006 by scientists from the Institute of Solid State Physics, University of Latvia. The warm welcome and open atmosphere of this scientific conference has turned it into an event where people from different countries and different fields come and meet under the shared umbrella of functional materials and nanotechnology. It is particularly important for early stage scientists who are looking for new knowledge and contacts with people from various fields to build their own network. Our Latvian colleagues, with their success in internationalization, made us neighbouring Estonians so jealous that we could not help but propose organising the conference every second year in Estonia. In a way, this conference is a continuation of the idea of the famous Baltic seminars which took place over several decades in the last century. Due to political constraints, these seminars were only open to scientists of former Eastern Europe countries, but had a great popularity and attendance from over the whole Soviet Union. Many collaborations started from the initial personal contact between scientists at these twice yearly seminars, held alternately in Latvia and Estonia. At the FM&NT 2012 conference, the decision was made that Institute of Physics, University of Tartu would organise the next event in Tartu in 2013. FM&NT-2013 was hence held in Tartu (Estonia) from 21-24 April 2013 at the Dorpat Conference Centre. The main selected topics of the conference were: (i) multifunctional materials, (ii) nanomaterials, (iii) materials for sustainable energy applications and (vi) theory. Additionally, the focus in this conference was on studies with the help of synchrotron radiation and other novel light sources such as free electron lasers.

    The objective of the study was to evaluate preteen insulin and metabolic syndrome (MS) as independent predictors of impaired fasting glucose (IFG) and type 2 diabetes mellitus (T2DM) in black and white females by mean age of 24 years. This was a prospective cohort study. There were 8 measures of fasting glucose and insulin from mean age of 10 years through mean age of 24 years, and insulin also at mean age of 25 years. Childhood MS was defined by at least 3 abnormal values among waist circumference, triglyceride, high-density lipoprotein cholesterol, blood pressure, and glucose. Hyperinsulinemia was defined by insulin greater than or equal to race-specific 75th percentile. Patients with type 1 diabetes mellitus were excluded. The study was held in schools and in an outpatient clinical center. Participants were schoolgirls (260 white, 296 black). There was no intervention. The outcome measures were IFG (fasting glucose of at least 100 to 125 mg/dL) and T2DM (fasting glucose of at least 126 mg/dL). By the age of 24 years, there were 11 cases of T2DM (2%) and 108 cases of IFG (19%). By the age of 24 years, IFG + T2DM was present in 18% of women (73/412) who had normal insulin-no MS at the age of 10 years vs 28% (34/122) of those with high insulin-no MS at the age of 10 years (P = .014) and 67% (10/15) of those with high insulin + MS at the age of 10 years (P < .0001). By stepwise logistic regression, significant, independent, positive predictors of IFG + T2DM were first insulin measure in childhood, age at last sampling, childhood MS, change in body mass index over 15 years, and, separately, initial glucose of at least 100 mg/dL and average of all insulin quartile ranks over 15 years. The correlation between childhood insulin z score and insulin z score 15 years later was r = .30, P < .0001. Insulin and MS at a mean age of 10 years plus change in body mass index over 15 years, and 15-year average insulin rank independently predict IFG + T2DM by mean age of 24 years

    2011-01-01

    Background A previous study found marked differences in smoking between employees in various university faculties in Tartu, Estonia, soon after the disruption of communism. The present study was conducted to see whether such differences still exist and how the patterns had changed during the country's first transitional decade. Methods All employees at the University of Tartu (UT) were surveyed for smoking habits by means of a questionnaire in 1992 and 2003. The present paper is based on respondents whose faculty or workplace was known (1390 people in 1992, 1790 in 2003). Smoking differences were assessed in terms of regression-based adjusted figures. Results While 20% of the male employees smoked daily in 1992, 13% did so in 2003, the figures for females being 10% and 7%, respectively. The prevalence of men's daily smoking varied between faculties and other workplaces in the range 4-30% in 1992, and 0-24% in 2003, with corresponding ranges of 3-21% and 0-10% among females. Men in the medical faculty in both surveys, and those in the faculty of philosophy in the second survey showed higher rates than men in most other faculties, as did women in the faculty of law in the first survey and those in the faculty of philosophy in the second. The figures were usually low in the faculties of sports & exercise, physics & chemistry and mathematics. The sex pattern was reversed in the faculty of law and also in that of economics, where the women smoked more than the men. Conclusions Even in this low-smoking academic community, wide smoking differences existed between the faculties and other workplaces. Faculties where physical or mental performance is of prime importance are leading the way towards a smoke-free community, while men in the faculty of philosophy and, paradoxically, men in the medical faculty are lagging behind. The reversed sex ratio in the faculties of law and economics may indicate women's intensified drive for equality in this transitional society. We assume

    The relationship between exposure to traffic induced particles, respiratory health and cardiac diseases was studied in the RHINE Tartu cohort. A postal questionnaire with commonly used questions regarding respiratory symptoms, cardiac disease, lifestyle issues such as smoking habits, indoor environment, occupation, early life exposure and sleep disorders was sent to 2,460 adults. The annual concentrations of local traffic induced particles were modelled with an atmospheric dispersion model with traffic flow data, and obtained PM(exhaust) concentrations in 40 x 40 m grids were linked with home addresses with GIS. The relationship between the level of exhaust particles outside home and self-reported health problems were analyzed using a multiple logistic regression model. We found a significant relation between fine exhaust particles and cardiac disease, OR = 1.64 (95% CI 1.12-2.43) for increase in PM(exhaust) corresponding to the fifth to the 95th percentile range. The associations also were positive but non-significant for hypertension OR = 1.42 (95% CI 0.94-2.13), shortness of breath OR = 1.27 (95% CI 0.84-1.94) and other respiratory symptoms. PMID:20049219

    In this paper, the authors study the correlation which exists between somatic development, represented by weight, height and thorax, and the age of onset of menarche. The results indicate that girls showing early menarche have a somatic development greater than the mean. It has also been possible to show that the greatest increase in height occurs before the menarche, while the greatest increase in weight coincides with the appearance of the menarche, or occurs shortly afterwards.

    In a national sample of 16-year-old girls who were aged 12 when the rubella vaccine programme was implemented in 1970, 71% were reported to have received rubella vaccine. There was a high regional disparity in the uptake of rubella vaccine: 81% of girls living in Scotland had been vaccinated but only 61% of girls living in Wales. Similarly there was a difference in reported vaccine uptake according to the family social background, the lowest proportion vaccinated came from professional and unskilled manual families. Girls attending independent schools also had a lower vaccine uptake than girls in schools maintained by the local educational authorities. If rubella immunisation is to be effective uptake of vaccine must increase to almost 100%. PMID:856383

    308 female students from six State high schools in inner metropolitan Sydney responded to self-administered questionnaires on their sex behavior and contraceptive use. Respondents were in their tenth year of school and of mean age 15.6 years. The survey was conducted with no refusals over the period March-June 1991 upon the sample from four coed and two single-sex schools. 18% of the sample reported ever having sexual intercourse, although substantial interschool variation was observed; less than 5% of girls in one school with a predominantly non-English speaking population were sexually experienced, while almost 45% were experienced in another school with a predominantly Anglo-Saxon population. The mean age at first intercourse for the sexually active group was 14.5 years. 72% used condoms at first intercourse, while 17% used no form of contraception. There were no significant differences in the mean ages of sexually active and nonactive girls, nor between the percentage of sexually active girls in coed schools and in single-sex schools. 25 girls had ever had a total of one sex partner, 27 had 2-5, and two had more than five. The condom is the most commonly used form of contraception, with 38% of sexually active girls using condoms every time. The rest of the girls used them either occasionally or not at all. Oral contraceptive pills (OCP) were used by less than 15% of the sexually active group, with effective contraception overall used by only 43% of the group. Effective contraception is defined as either condom use during every act of sexual intercourse during the preceding six months or daily compliance with the OCP. Eight subjects used no contraception at all during the preceding six months. These findings indicate the need for more education targeted to adolescents and health professionals, especially general practitioners. PMID:12318952

  9. Costs of delivering human papillomavirus vaccination to schoolgirls in Mwanza Region, Tanzania

    2012-01-01

    Background Cervical cancer is the leading cause of female cancer-related deaths in Tanzania. Vaccination against human papillomavirus (HPV) offers a new opportunity to control this disease. This study aimed to estimate the costs of a school-based HPV vaccination project in three districts in Mwanza Region (NCT ID: NCT01173900), Tanzania and to model incremental scaled-up costs of a regional vaccination program. Methods We first conducted a top-down cost analysis of the vaccination project, comparing observed costs of age-based (girls born in 1998) and class-based (class 6) vaccine delivery in a total of 134 primary schools. Based on the observed project costs, we then modeled incremental costs of a scaled-up vaccination program for Mwanza Region from the perspective of the Tanzanian government, assuming that HPV vaccines would be delivered through the Expanded Programme on Immunization (EPI). Results Total economic project costs for delivering 3 doses of HPV vaccine to 4,211 girls were estimated at about US$349,400 (including a vaccine price of US$5 per dose). Costs per fully-immunized girl were lower for class-based delivery than for age-based delivery. Incremental economic scaled-up costs for class-based vaccination of 50,290 girls in Mwanza Region were estimated at US$1.3 million. Economic scaled-up costs per fully-immunized girl were US$26.41, including HPV vaccine at US$5 per dose. Excluding vaccine costs, vaccine could be delivered at an incremental economic cost of US$3.09 per dose and US$9.76 per fully-immunized girl. Financial scaled-up costs, excluding costs of the vaccine and salaries of existing staff were estimated at US$1.73 per dose. Conclusions Project costs of class-based vaccination were found to be below those of age-based vaccination because of more eligible girls being identified and higher vaccine uptake. We estimate that vaccine can be delivered at costs that would make HPV vaccination a very cost-effective intervention. Potentially, integrating HPV vaccine delivery with cost-effective school-based health interventions and a reduction of vaccine price below US$5 per dose would further reduce the costs per fully HPV-immunized girl.

    Viewing free online pornographic videos has increasingly become a common behavior among young people, although little is known about the content of these videos. The current study analyzed the content of two popular female-age-based types of free, online pornography (teen and MILF) and examined nuances in the portrayal of gender and access to power in relation to the age of the female actor. A total of 100 videos were selected from 10 popular Web sites, and their content was coded using independent raters. Vaginal intercourse and fellatio were the most frequently depicted sexual acts. The use of sex toys, paraphilias, cuddling, and condom use were rare, as were depictions of coercion. Control of the pace and direction of sexual activity was typically shared by the male and female actors. Moreover, there were no gender differences in initiation of sexual activity, use of persuasion, portrayals of sexual experience, or in professional status. However, female actors in MILF videos were portrayed as more agentic and were more likely to initiate sexual activity, control the pace of sexual activity, and have a higher professional status. Implications regarding the role of pornography in generating or reinforcing sexual norms or scripts are discussed.

    1992-04-01

    Interviews conducted with 100 Bahraini female secondary school students 15-17 years old revealed highly positive attitudes toward breast feeding. The majority (68 girls) were themselves breast fed as infants; 10 were bottle-fed and 2 received mixed feeds, while another 20 could not recall their type of feeding. Although only 52 girls had received school-based education about infant feeding, 91 had heard or read about this topic independently. Of the 93 girls who expressed a desire to have children in the future, 84 planned to breast feed and 10 intended to provide both breast and bottle-feeding. Breast feeding was favored because it was sterile and clean. Most girls intended to breast feed until their child was 2 years old; the mean duration of intended breast feeding was 19 months. The choice of feeding method and the duration of breast feeding were positively influenced by observing a relative or neighbor who breast-fed.

    Einführung: In Deutschland wurde die Implementierung der Humanen Papillomavirus (HPV)-Impfung für 12–17-jährige Mädchen von diversen Kampagnen begleitet. Evidenz-basierte Informationen, die Zahlenangaben beinhalten, wurden nicht zur Verfügung gestellt. Stattdessen führten die Standardinformationen zu einer Überschätzung des Krebsrisikos und den Effekten der HPV-Impfung. Das Vertrauen in die Fähigkeit von Kindern mit Risiken umzugehen ist gering, insbesondere wenn es sich um sozial benachteiligte Schüler handelt. Das Ziel dieser Studie ist ein Vergleich der Effekte eines Standard-Flyers mit einem Informationsflyer, der Zahlenangaben beinhaltet, hinsichtlich des Risikowissens über die HPV-Impfung bei Schülerinnen. Methoden: Randomisiert-kontrollierte Kurzzeitstudie. Es wurden alle 108 Schülerinnen aus sieben Schulklassen auf die Teilnahme angesprochen und 105 stimmten zu. Die Teilnehmerinnen waren Berufsfachschülerinnen, die den Abschluss der 10. Klasse anstrebten und zur Zielgruppe für eine HPV-Impfung gehörten. Die Kontrollgruppe wurde gebeten, den Standardflyer des Nationalen Netzwerks Frauen und Gesundheit zu lesen. Die Interventionsgruppe erhielt den gleichen Flyer, der jedoch mit numerischen Informationen zum Krebsrisiko und zu den angenommenen Effekten der HPV-Impfung auf die Krebsprävention ergänzt worden war. Als Basischarakteristika wurden Alter, Impfstatus, Einstellung zur HPV-Impfung und Aspekte bezüglich des Migrationshintergrunds erhoben. Der primäre Endpunkt war Risikowissen. Die Fragebogenerhebungen erfolgten unter experimentellen Bedingungen. Die individuelle Randomisierung, die Teilnehmerinnen und die intention-to-treat Datenanalyse waren verblindet. Die Studie wurde vom Ministerium für Bildung und Kultur des Landes Schleswig-Holstein und der Ethikkommission der Hamburger Ärztekammer genehmigt. Ergebnisse: Risikowissen wurde für alle 105 randomisierten Teilnehmerinnen analysiert. Die Basischarakteristika der beiden Gruppen waren vergleichbar. Die Schülerinnen, die den Flyer mit Zahlenangaben erhielten, gaben häufiger korrekte Antworten im Vergleich zur Kontrollgruppe mit der Standardinformation: Mittelwert des Risikowissens (0–5 Punkte): 4,6±1,0 vs. 2,6±1,2 (Differenz 2,0 (95% CI 1,6–2,4)); (P<0,001). Post hoc wurde eine Distraktorenanalyse der einzelnen Items durchgeführt. Die inkorrekten Antworten der Teilnehmerinnen der Kontrollgruppe zeigten, dass das Zervixkarzinom-Risiko stark überschätzt wurde, das Risiko für Krebserkrankungen im Allgemeinen meist unterschätzt wurde und der mögliche Einfluss der HPV-Impfung auf die Krebsprävention überschätzt wurde. Schlussfolgerung: Die Ergänzung eines Informationsflyers zur HPV-Impfung mit Zahlenangaben verbesserte das Risikowissen von Schülerinnen.

  19. Ethical Obligations in the Face of Dilemmas Concerning Patient Privacy and Public Interests: The Sasebo Schoolgirl Murder Case.

    2016-09-01

    A murder case that had some features in common with the Tarasoff case occurred in Sasebo City, Japan, in 2014. A 15-year-old high school girl was murdered and her 16-year-old classmate was arrested on suspicion of homicide. One and a half months before the murder, a psychiatrist who had been examining the girl called a prefectural child consultation centre to warn that she might commit murder, but he did not reveal her name, considering it his professional duty to keep it confidential. Article 134 of the Japanese Criminal Law states that doctors should not disclose patient information obtained in clinical practice without a legitimate reason, but the Japanese Supreme Court has not specified what constitutes a legitimate reason. Mass media and commentators suggested that the murder could have been prevented if the psychiatrist had disclosed the girl's name to the authorities or had isolated her coercively in a psychiatric ward. However, the authors disagree with such claims. This article discusses obligations imposed on concerned individuals and third party members in cases involving ethical dilemmas regarding patient confidentiality and information disclosure. It is concluded that everyone should fulfill their obligations to prevent such tragedies and one should judge the appropriateness of others' actions based not on the consequences of their actions, but on the processes used to decide on a course of action and their commitment. It is necessary for us to establish a society in which concerned parties can do what they think is ethically best without fearing ungrounded charges. PMID:26833626

  10. "They arrested me for loving a schoolgirl": ethnography, HIV, and a feminist assessment of the age of consent law as a gender-based structural intervention in Uganda.

    PubMed

    Parikh, Shanti A

    2012-06-01

    In 1990 women's rights activists in Uganda successfully lobbied to amend the Defilement Law, raising the age of sexual consent for adolescent females from fourteen to eighteen years old and increasing the maximum sentence to death by hanging. The amendment can be considered a macro-level intervention designed to address the social and health inequalities affecting young women and girls, particularly their disproportionately high rate of HIV as compared to their male counterparts. While the intention of the law and aggressive campaign was to prosecute "sugar daddies" and "pedophiles," the average age of men charged with defilement was twenty-one years old and many were believe to be "boyfriends" in consensual sexual liaisons with the alleged victims. This article uses court records, case studies, and longitudinal ethnographic data gathered in east-central Uganda to examine the impact of the age of consent law at national and local levels, and specifically what the disjunctures between national intentions and local uses reveal about conflicting views about sexual privilege and rights. I argue that existing class, gender, and age hierarchies have shaped how the Defilement Law has been applied locally, such that despite the stated aim of "protecting" young women, the law reinstates patriarchal privilege (especially against men of lower social class) while simultaneously increasing the regulation of adolescent female sexuality and undermining their autonomy. This paper demonstrates how ethnography and critical gender theory-which emphasizes the intersectionality of gender, age, and class in the (re)production of inequalities-can be used to examine consequences of macro-level interventions in ways that may be undetected in conventional public health evaluation techniques but that are crucial for designing and modifying effective interventions.

  12. Is expanding HPV vaccination programs to include school-aged boys likely to be value-for-money: a cost-utility analysis in a country with an existing school-girl program

    PubMed Central

    2014-01-01

    Background Similar to many developed countries, vaccination against human papillomavirus (HPV) is provided only to girls in New Zealand and coverage is relatively low (47% in school-aged girls for dose 3). Some jurisdictions have already extended HPV vaccination to school-aged boys. Thus, exploration of the cost-utility of adding boys’ vaccination is relevant. We modeled the incremental health gain and costs for extending the current girls-only program to boys, intensifying the current girls-only program to achieve 73% coverage, and extension of the intensive program to boys. Methods A Markov macro-simulation model, which accounted for herd immunity, was developed for an annual cohort of 12-year-olds in 2011 and included the future health states of: cervical cancer, pre-cancer (CIN I to III), genital warts, and three other HPV-related cancers. In each state, health sector costs, including additional health costs from extra life, and quality-adjusted life-years (QALYs) were accumulated. The model included New Zealand data on cancer incidence and survival, and other cause mortality (all by sex, age, ethnicity and deprivation). Results At an assumed local willingness-to-pay threshold of US$29,600, vaccination of 12-year-old boys to achieve the current coverage for girls would not be cost-effective, at US$61,400/QALY gained (95% UI $29,700 to $112,000; OECD purchasing power parities) compared to the current girls-only program, with an assumed vaccine cost of US$59 (NZ$113). This was dominated though by the intensified girls-only program; US$17,400/QALY gained (95% UI: dominant to $46,100). Adding boys to this intensified program was also not cost-effective; US$128,000/QALY gained, 95% UI: $61,900 to $247,000). Vaccination of boys was not found to be cost-effective, even for additional scenarios with very low vaccine or program administration costs – only when combined vaccine and administration costs were NZ$125 or lower per dose was vaccination of boys cost-effective. Conclusions These results suggest that adding boys to the girls-only HPV vaccination program in New Zealand is highly unlikely to be cost-effective. In order for vaccination of males to become cost-effective in New Zealand, vaccine would need to be supplied at very low prices and administration costs would need to be minimised. PMID:24965837

    2015-01-01

    Education is an effective way to improve girls' self-worth, health, and productivity; however there remains a gender gap between girls' and boys' completion of school. The literature around factors influencing girls' decision to stay in school is limited. Seven focus group discussions took place among 79 girls in forms 2 to 4 at secondary schools in rural western Kenya, to examine their views on why girls absent themselves or dropout from school. Data were analysed thematically. Lack of resources, sexual relationships with boyfriends, and menstrual care problems were reported to lead directly to dropout or school absence. These were tied to girls increased vulnerability to pregnancy, poor performance in school, and punishments, which further increase school absence and risk of dropout. Poverty, unmet essential needs, coercive sexual relationships, and an inequitable school environment collude to counter girls' resolve to complete their schooling. Lack of resources drive girls to have sex with boyfriends or men who provide them with essentials their family cannot afford, such as sanitary pads and transport to school. While these improve quality of their school life, this dynamic increases their exposure to sexual risk, pregnancy, punishment, and dropout. Evaluation of interventions to ameliorate these challenges is warranted, including provision of pocket money to address their needs. PMID:26636771

    2016-01-01

    Although frequently used with older adolescents, few studies of the factor structure, internal consistency and gender equivalence of the SDQ exists for this age group, with inconsistent findings. In the present study, confirmatory factor analysis (CFA) was used to evaluate the five-factor structure of the SDQ in a population sample of 10,254 16-18 year-olds from the youth@hordaland study. Measurement invariance across gender was assessed using multigroup CFA. A modestly modified five-factor solution fitted the data acceptably, accounting for one cross loading and some local dependencies. Importantly, partial measurement non-invariance was identified, with differential item functioning in eight items, and higher correlations between emotional and conduct problems for boys compared to girls. Implications for use clinically and in research are discussed.

    2011-01-01

    Using a nationally representative sample of 142 783 middle school (13-15 years old) and high school (16-18 years old) students in South Korea, this study examined whether (1) overweight and obesity are more likely to be associated with lower self-reported school performance; (2) overweight and obese students are more likely to enrol in a vocational high school as opposed to a general high school; (3) the association between obesity and poorer self-reported school performance is mediated through body image stress and health status. We found that excess weight was negatively associated with self-reported school performance among middle and general high school students, and that obese students had a higher probability of being enrolled in a vocational over a general high school. We did not find strong evidence on the mediating role of body image stress and health status.

    Objective To assess the cost effectiveness of routine vaccination of 12 year old schoolgirls against human papillomavirus infection in the United Kingdom. Design Economic evaluation. Setting UK. Population Schoolgirls aged 12 or older. Main outcome measures Costs, quality adjusted life years (QALYs), and incremental cost effectiveness ratios for a range of vaccination options. Results Vaccinating 12 year old schoolgirls with a quadrivalent vaccine at 80% coverage is likely to be cost effective at a willingness to pay threshold of £30 000 (€37 700; $59 163) per QALY gained, if the average duration of protection from the vaccine is more than 10 years. Implementing a catch-up campaign of girls up to age 18 is likely to be cost effective. Vaccination of boys is unlikely to be cost effective. A bivalent vaccine with the same efficacy against human papillomavirus types 16 and 18 costing £13-£21 less per dose (depending on the duration of vaccine protection) may be as cost effective as the quadrivalent vaccine although less effective as it does not prevent anogenital warts. Conclusions Routine vaccination of 12 year old schoolgirls combined with an initial catch-up campaign up to age 18 is likely to be cost effective in the UK. The results are robust to uncertainty in many parameters and processes. A key influential variable is the duration of vaccine protection. PMID:18640957

    2008-05-01

    Research examining parenting factors in the development of anxiety has focused largely on the concepts of parental warmth and overcontrolling or intrusive parenting, This study investigated the relationship between these factors, and also parental discipline style and anxiety using self-report methodology with a sample of 16-18 year olds. In order to try to explain the relationship between parenting and anxiety, measures of cognition were also included. A multiple regression was conducted including all parenting factors as predictors of trait anxiety. The regression was a modest fit (R(2)=22%) and the model was significant (F(4, 141)=9.90, p<0.0001). Only the effect of Over-reactivity was significant, (t=3.72, p<0.0001). Furthermore, Over-reactive discipline was significantly associated with increased cognitive distortions (r=0.361 p<0.0001) and metacognition (r=0.396 p<0.0001). Both cognitive distortions and metacognition were found to partially mediate the relationship between discipline style and trait anxiety. The implications of these findings and areas for future research are discussed.

    Abrams, D; Sheeran, P; Abraham, C; Spears, R

    1992-01-01

    A survey examined health beliefs and intentions among 690 16-18 year-olds in Dundee. Respondents in the younger cohort (n = 363) were classified according to their educational situation (at school vs left) and self-reports of having received AIDS/HIV-relevant health education. Both remaining in school and receiving AIDS/HIV-relevant health education had independent beneficial effects, but the effects of leaving school also interacted with sex of respondent and with amount of relevant education received prior to leaving. Males' and females' reliance on mass media and other information sources diverged once they left school, indicating that males who leave school early are most likely to disregard useful or important information regarding AIDS. Consistent with this finding, leaving school reduced the difference between males' and females' intention to use condoms with a new partner. The beneficial impact of having previously received AIDS/HIV-relevant education on beliefs concerning the controllability of the epidemic and on feeling worried about everyday contact with a person with HIV/AIDS, was most marked among those who had left school. The results are discussed in terms of their implications for health education strategies. PMID:1525198

  17. German high school students' attitudes and interest in cancer and factors influencing proactive behaviour for cancer prevention.

    PubMed

    Heuckmann, Benedikt; Asshoff, Roman

    2014-09-01

    Cancer diseases are pertinent topics to young people, who are confronted with the issue through media or family members that suffer from these diseases. Based on a paper-and-pencil questionnaire, we investigated German high school students' (N = 369, 16-18 years old) interest in and their attitudes towards cancer. Attitude was assessed measuring multiple dimensions that included scales to measure several components: the cognitive (beliefs about the controllability of cancer), the affective (emotional responses towards cancer) and the behavioural (intention for proactive behaviour towards cancer) components. A student assessment of carcinogenic risk factor was executed. Our results suggest that students' willingness to deal with the topic cancer (e.g. to communicate about cancer or to reconsider their lifestyle) is highly dependent on their interest, their emotional responses and their beliefs about the controllability of cancer. Their assessment of carcinogenic risk factors does not have a direct influence on their intentions to behave proactively against cancer but might have an indirect influence on their beliefs about the controllability of cancer. Based on these results, we have drawn teaching implications and discussed which factors should be included in teaching processes in order to stimulate proactive behaviour related to cancer prevention.

The study involved 90 adolescents 16-18 years old with left varicocele and disturbances in ejaculate parameters, of which 60 had pelvic congestion. Patients and control group received a comprehensive treatment, including preoperative trophic and flebotonic therapy, laparoscopic surgical clipping of the internal spermatic vein and post-operative rehabilitation. Patients of the study group along with this treatment received prostatotropic drug Vitaprost. According to the results of study, it was found that in patients with varicocele, attention should pay to the status of the venous outflow from the pelvic organs, which leads to the pelvic congestion and causes degenerative changes in the prostate in half of cases, which in turn negatively affects the spermogram parameters and increases the risk of subfertility. The use of prostatotropic drugs in the treatment of patients suffering from varicoceles with pelvic congestion is appropriate and pathogenetically justified, as it promotes a more rapid restoration of the structure and function of the prostate.

    Effectively reducing adolescents' risky sexual behaviors has been an urgent need since the HIV/AIDS infections among young people has been acknowledged as a priority. Self-efficacy has been considered playing an essential role in behavioral changes, and depressed individuals may demonstrate lower self-efficacy. The purpose of this cross-sectional study was to gain insights into self-reported depression among 16-18 years-old Taiwanese adolescents as well as to explore psychosocial predictors of AIDS preventive self-efficacy. A convenience sample of 734 adolescents from southern Taiwan was recruited, and several reliable and valid questionnaires were used to collect data. Descriptive statistics, odds ratio, independent t-test, and hierarchical multiple regression analyses were utilized to analyze data. Results showed that the differences in self-reported depression and in the AIDS preventive self-efficacy varied by gender, substance use, and having sexual experience. Furthermore, depression was a significant predictor of AIDS preventive self-efficacy while controlling the covariates. This study suggests that gender and mental health status such as depression may play significant roles in AIDS preventive self-efficacy. Nurses and health care providers should take the influence of mental health into consideration when designing AIDS preventive interventions for male and female Taiwanese adolescents. The provided information may also enhance psychiatric nurses' capability to provide care and to enhance the prevention of HIV infection for adolescents. PMID:26804507

    Increasing rates of overweight and eating disorders among young people are a concern. The aim of this study was to compare the prevalence of overweight/obesity among Cypriot adolescents between cohorts from 2003 and 2010 and to determine whether body mass index (BMI) was associated with psychological traits linked to eating disorders. Anthropometric measures were done on a representative sample of students aged 10-18 years and the Eating Disorder Inventory-3rd version (EDI-3) and 26-item Eating Attitudes Test (EAT-26) scales were completed by 13-18-year-olds. Mean waist circumference of the 2010 cohort of 10-18-year-olds was 3.6 cm higher in boys and 5.5 cm higher in girls than the 2003 cohort. Mean BMI was higher in 2010 only in the 16-18-year-old age group. More adolescents on the higher end of the weight spectrum had pathological scores n the eating disorder scales. Obesity and maladaptive eating attitudes are common in Cypriot adolescents.

    Information about pornography-viewing habits of urban, low income, youth of color in the U.S. is lacking. This study was designed to answer the following using a sample of 16-18 year old urban-residing, low income, Black or Hispanic youth: (1) What types of pornography do youth report watching, where, and for what purpose?; (2) Do youth feel that pornography exposure has an impact on their own sexual behaviors?; and (3) How do parents react to their pornography use? The following themes emerged from interviews with 23 youth: (a) Youth primarily reported watching pornography that featured one-on-one sexual intercourse, but also reported having seen extreme pornography (e.g., public humiliation, incest); (b) youth reported watching pornography on home computers or smartphones, and that pornography was frequently watched in school; (c) youth reported watching for entertainment, for sexual stimulation, instructional purposes, and to alleviate boredom; many copied what they saw in pornography during their own sexual encounters; (d) pressure to make or to imitate pornography was an element of some unhealthy dating relationships; and (e) parents were generally described as unsupportive of youths’ use of pornography, but under-equipped to discuss it. Approximately one-fifth expressed a prefererence for pornography featuring actors of their same race/ethnicity. PMID:25350847

    A survey examined health beliefs and intentions among 690 16-18 year-olds in Dundee. Respondents in the younger cohort (n = 363) were classified according to their educational situation (at school vs left) and self-reports of having received AIDS/HIV-relevant health education. Both remaining in school and receiving AIDS/HIV-relevant health education had independent beneficial effects, but the effects of leaving school also interacted with sex of respondent and with amount of relevant education received prior to leaving. Males' and females' reliance on mass media and other information sources diverged once they left school, indicating that males who leave school early are most likely to disregard useful or important information regarding AIDS. Consistent with this finding, leaving school reduced the difference between males' and females' intention to use condoms with a new partner. The beneficial impact of having previously received AIDS/HIV-relevant education on beliefs concerning the controllability of the epidemic and on feeling worried about everyday contact with a person with HIV/AIDS, was most marked among those who had left school. The results are discussed in terms of their implications for health education strategies.

    Individuals with Attention Deficit Hyperactivity Disorder (ADHD) have difficulties in achieving optimal performance in many everyday and academic tasks, deficits attributed to impaired skill acquisition and procedural memory consolidation. We tested the effect of a skipped dose of methylphenidate (MPH) on learning a movement sequence and its subsequent consolidation into procedural memory in adolescents with ADHD. A crossover double-blind design with placebo was used. Sixteen male adolescents, 16-18 years-old, with ADHD and taking MPH formulations on a daily basis, were trained on performing a 5-element sequence of finger-to-thumb opposition movements. Participants took part in two study conditions, 2 months apart. In each condition a different movement sequence was trained and tested. Participants trained on the task either with active medication or placebo on the day of training, crossed-over between study conditions. Learning effects, speed and accuracy, were assessed within-session, during a 24-h memory consolidation phase. Retention was tested by 2 weeks post-training. There were robust gains in performance both within-session and during the 24-h consolidation phase, in both conditions. However, the discontinuation of MPH on the day of training significantly reduced performance speed, with no loss of accuracy. By 2 weeks, post-training performance was comparable. Adolescents with ADHD who are treated daily but skip a dose of MPH show significant slowing of performance relative to their own performance on medication. However, on a background of daily treatment a skipped dose has no deleterious effect on memory consolidation and retention.

    Teaching students, aged from 4 up to 18 years old, is a challenging task. It continuously implies new strategies and new subjects adapted to all of them. This is even more evident, when we have to teach natural-hazards scientific aspects and safe attitudes toward risk. We often see that most of the high-school students (16 -18 years old) are not motivated for extra-curricular activities implying science and/or behaviours changes. But, they have a very positive response when we give them some responsibility. On top of that, we also realised that young children are quite receptive to the involvement of older students in the school environment Taking this into consideration, our project use the k12 students to prepare scientific activities and subjects, based in questions, which they need to answer themselves. The students need to answer those questions and, only then, adapt and teach the right answers to the different school-levels. With this approach, we challenged the students to solve three questions: How to use a SEP seismometer at school, and its data? How to set up a shaking table? How to introduce waves and vibrations contents to all ages of students? During the project they developed many science skills, and worked in straight cooperation with teachers, the parents association and the seismology research group at Instituto Dom Luíz. As a result, it was possible to reach all school students with the help of the k-12 ones. This is an outcome of the project W-Shake, a Parents-in-Science Initiative to promote the study of seismology and related subjects. This project, supported by the Portuguese "Ciência Viva" program, results from a direct cooperation between the parents association, science school-teachers and the seismology research group at Instituto Dom Luíz.

    1995-01-01

    This article offers 12 suggestions for improving the protection of sexually victimized children and discusses the extent, form, causes, and consequences of sexual victimization of female children in India. Female victimization includes child marriage, polygamy, rape, incest, and kidnapping for immoral purposes. A female child is victimized from birth to maturity. Girls are born into a secondary status and married off. If her dowry is meager, a girl is subjected to ridicule, criticism, or denigration. The number of prosecuted sex offenses against girls and the number of reported sex offenses increased during 1980-89. However, most sex offenses are unreported. About 63% of rape cases pertain to girls 16-30 years old. Only 18% of rape cases occur among women over age 30. During 1971-89, kidnapping increased by over 79%. Most kidnapping involves girls 3-16 years old and is connected with prostitution, begging, sexual gratification, unemployment, extreme poverty, broken homes, and antisocial surroundings. One study in 1991 found that 48% of adolescent school girls had been molested. Another study in 1985 found that 54.29% of rape victims were 7-16 years old, and 3.27% were under 7 years old. 53.88% were unmarried, and 45.32% were married. Most of the victims were unemployed, dependents, or students. Most rapists are known by the victims. The rapist and the victims tend to come from middle or lower socioeconomic classes. Brother-sister incest is about 5 times more common than father-daughter incest. The literature suggests that children are sexually abused for pleasure or material gain. A current city study found that 15% of prostitutes were under 15 years old; 24.5% were 16-18 years old. Girls enter prostitution through a temple devdasi life, abduction, regular employment, and initiation by parents and brothel keepers. Marriage victimizes girls who marry at an early age or with a poor dowry. PMID:12158001

    This study has been carried out within the REVIR scenario, which is a project promoting that secondary school students have access to a computerized laboratory at the Faculty of Education of our university and work in small groups during four hours with specific instructional material. One of the laboratory sessions included in the REVIR project deals with IR radiation-matter interaction, and is addressed to post-compulsory secondary students (16-18 year-old students). Within this framework, we have conducted a research study to analyse students' conceptualizations of the processes or mechanisms that take place in IR radiation-matter interaction (energy transfer, selective absorption), and its effects at a macroscopic level (temperature increase) and at a molecular level (vibration). For data collection, a question was posed to all students at the end of each REVIR session, asking students to relate what was described in an article about the application of an IR laser for acne treatment to what they had learnt throughout the session. The analysis of the 67 students' answers to that question revealed that many students explained the effects of the IR laser in vague terms, often repeating information included in the article, without explaining absorption of IR radiation in terms of energy. In consecutive versions of the instructional material, more oriented application questions were added after the article and explicit discussion around synthesis and exploratory (of students' previous ideas) questions was carried out during the session. From the analysis of 49 and 119 students' answers in consecutive later versions, we found that the introduction of these changes resulted in a greater number of students' descriptions in macroscopic and microscopic terms, and a lower number of answers simply repeating information extracted from the reading. Furthermore, more students explicitly explained absorption in terms of energy associated to IR light. Implications for the

    Background Bullying is quite prevalent in the school setting and has been associated with the socioeconomic position and psychiatric morbidity of the pupils. The aim of the study was to investigate the association between bullying and socioeconomic status in a sample of Greek adolescents and to examine whether this is confounded by the presence of psychiatric morbidity, including sub-threshold forms of illness. Methods 5,614 adolescents aged 16-18 years old and attending 25 senior high schools were screened and a stratified random sample of 2,427 were selected for a detailed interview. Psychiatric morbidity was assessed with a fully structured psychiatric interview, the revised Clinical Interview Schedule (CIS-R), while bullying was assessed with the revised Olweus bully/victim questionnaire. The following socio-economic variables were assessed: parental educational level and employment status, financial difficulties of the family and adolescents' school performance. The associations were investigated using multinomial logit models. Results 26.4% of the pupils were involved in bullying-related behaviours at least once monthly either as victims, perpetrators or both, while more frequent involvement (at least once weekly) was reported by 4.1%. Psychiatric morbidity was associated with all types of bullying-related behaviours. No socioeconomic associations were reported for victimization. A lower school performance and unemployment of the father were significantly more likely among perpetrators, while economic inactivity of the mother was more likely in pupils who were both victims and perpetrators. These results were largely confirmed when we focused on high frequency behaviours only. In addition, being overweight increased the risk of frequent victimization. Conclusions The prevalence of bullying among Greek pupils is substantial. Perpetration was associated with some dimensions of adolescents' socioeconomic status, while victimization showed no socioeconomic

    Objectives Reproductive tract infections (RTIs), including sexually acquired, among adolescent girls is a public health concern, but few studies have measured prevalence in low-middle-income countries. The objective of this study was to examine prevalence in rural schoolgirls in Kenya against their reported symptoms. Methods In 2013, a survey was conducted in 542 adolescent schoolgirls aged 14–17 years who were enrolled in a menstrual feasibility study. Vaginal self-swabbing was conducted after girls were interviewed face-to-face by trained nurses on symptoms. The prevalence of girls with symptoms and laboratory-confirmed infections, and the sensitivity, specificity, positive and negative predictive values of symptoms compared with laboratory results, were calculated. Results Of 515 girls agreeing to self-swab, 510 answered symptom questions. A quarter (24%) reported one or more symptoms; most commonly vaginal discharge (11%), pain (9%) or itching (4%). Laboratory tests confirmed 28% of girls had one or more RTI. Prevalence rose with age; among girls aged 16–17 years, 33% had infections. Bacterial vaginosis was the most common (18%), followed by Candida albicans (9%), Chlamydia trachomatis (3%), Trichomonas vaginalis (3%) and Neisseria gonorrhoeae (1%). Reported symptoms had a low sensitivity and positive predictive value. Three-quarters of girls with bacterial vaginosis and C. albicans, and 50% with T. vaginalis were asymptomatic. Conclusions There is a high prevalence of adolescent schoolgirls with RTI in rural Kenya. Public efforts are required to identify and treat infections among girls to reduce longer-term sequelae but poor reliability of symptom reporting minimises utility of symptom-based diagnosis in this population.

    In an effort to understand the strengths and limitations of current approaches to human papillomavirus vaccine (HPV) delivery in schools, we conducted an audit of nurse immunisers (NI). In this survey of 159 Victorian NI, the NI perceived that knowledge, safety and side effects were among the most important issues raised by parents, schoolgirls, and teachers in the school setting. The most common concern identified by NIs was the physical layout of the vaccination setting (41%), followed by safety, then knowledge of the vaccine. There is a need for ongoing assessment of factors that improve or impede the delivery of HPV vaccines. PMID:20719232

    The National Guard Youth ChalleNGe Program (ChalleNGe) is a 17 month quasi-military training program authorized by Congress in the 1993 Defense Authorization Bill designed to improve life skills, education levels, and employment potential of 16--18 year old youth who drop out of high school. ChalleNGe is currently operational in 27 states/territories with the focus of this study on the Mississippi National Guard Program operated at Camp Shelby, Mississippi. During the five month residential portion of the program students are guided through an eight step process designed to meet the goals of improving life skills, education levels, and employment potential while ultimately leading to completion of high school equivalency credentials followed by a 12 month mentoring phase to encourage and track progress toward goals. The purpose of this study was to investigate the attitude toward science of a group of students enrolled in the ChalleNGe Program at Camp Shelby (ChalleNGe). The GED test is administered approximately two months into the residential phase of the program. While the program boasts an overall GED pass rate of nearly 80%, approximately 30--35% of students successfully complete the initial offering of the GED. As high school graduates, these students are offered college courses through William Carey College in Hattiesburg, Mississippi. Twenty four students elected to take the Introduction to Environmental Science course and formed the experimental group while 24 other students who passed the GED comprised the control group. Each group was administered the Scientific Attitude Inventory II, a 40 statement instrument with Likert Scale responses, as a pretest. Paired samples t-tests indicated no significant difference in attitude toward science between the experimental and control groups on the pretest. Following the two week Introduction to Environmental Science course for the experimental group, both groups were post tested. As predicted, the attitude toward

The teams each focused on a theme related to solar research: "How does the Sun work?" (I), "The Sun as a star" (F), "Solar activity" (NL), "Observing the Sun" (D), "Humans and the Sun" (B), and built exhibition "modules" that they will present at the inauguration, in the context of European Science and Technology Week 2000 (6-10 November), promoted by the European Commission. During the two-day event, a jury of representatives of other European science and technology museums, ESA scientists, a science journalist, and two ESA astronauts (Frank de Winne and Andre Kuipers) will judge the youngsters' exhibition modules on the basis of their scientific correctness, their museological value and the commitment shown by the young "communication experts". The winning team will be officially announced on 9 November. The prize is a weekend at the Space Camp in Redu, Belgium. The objective of the European Project on the Sun is educational. It aims, through the direct and "fresh" involvement of youngsters, to heighten European citizens' awareness of space research in general and the Sun's influence on our daily lives in particular. The role of the European Space Agency as reference point in Europe for solar research has been fundamental to the project.

    2000-01-01

    To explore the socializing influences which have shaped rural adolescent schoolgirls' views and values about sex in a high HIV prevalence area of Uganda, detailed qualitative data were obtained over a 1-year period from 15 schoolgirls aged 14-17 years. The girls were chosen for their willingness to participate actively in a series of role plays, focus group discussions, and one-to-one interviews. Results indicated that the girls have been subjected to a wide range of influences, including parents, social functions, other young children, nature, their paternal aunt, peers, school, and various media, such as pornography. Moreover, there was disagreement about the relative values of sex and virginity. Some were determined to retain their virginity but the majority felt that sex benefits them socially and personally. Notably, peer pressure was a major factor influencing the opinions of many girls, while traditional influences are in decline. Given the small sample size of the study, care should be taken in generalizing from the results. However, the data suggest that sex has a high value for at least a substantial minority of adolescent girls in rural Misaka, Uganda. Policy makers and health educators should therefore consider how best to devise safe messages about sex that are relevant and applicable to this vulnerable segment of the population.

    In recent years, the menstrual hygiene management challenges facing schoolgirls in low-income-country contexts have gained global attention. We applied Gusfield's sociological analysis of the culture of public problems to better understand how this relatively newly recognized public health challenge rose to the level of global public health awareness and action. We similarly applied the conceptualization by Dorfman et al. of the role of public health messaging in changing corporate practice to explore the conceptual frames and the news frames that are being used to shape the perceptions of menstrual hygiene management as an issue of social justice within the context of public health. Important lessons were revealed for getting other public health problems onto the global-, national-, and local-level agendas.

    This study aimed to investigate the mediating role of early maladaptive schemas in the relationship between parental bonding and eating disorder symptoms in a group of female adolescents. Three hundred and sixty-seven female adolescents completed the Parental Bonding instrument [PBI; Brit. J. Med. Psychol. 52 (1979) 1-10], the Young Schema Questionnaire short version [YSQ; Young, J. E. (1998). The Young Schema Questionnaire: Short form. Available at ], and the Eating Attitudes Test [EAT; Psychol. Med. 9 (1979) 273-279]. Two underlying schemas, defectiveness/shame and dependence/incompetence, were perfect mediators in the relationship between parental bonding and eating disorder symptoms. Schemas relating to both shame and dependency may be important in determining the effect that parental bonding has on eating disorder symptoms in a sample of female adolescent schoolgirls.

Three years from the onset of her clinical signs she died of a sudden cardiac arrest caused by endocarditis associated with valvular and arterial lesions. Chlamydia psittaci was isolated from her conjunctiva. In her blood type-specific antichlamydial antibody at a level of 1/64 against her own isolate was detected. The clinical findings in this patient were suggestive of a Cogan's syndrome. It is highly probable that the chlamydia isolated from the eyes was responsible for her various lesions.

    Acculturation has been examined as a risk factor for eating disorders, but interpretation of findings has been limited by inconsistent operationalization of this construct across studies. The study aim was to develop and evaluate a population-specific measure of acculturation for ethnic Fijian adolescent schoolgirls, to use in future analyses related to eating disorders. Our findings suggest that acculturation is a multidimensional construct characterized by distinct, though related, dimensions of orientation to ethnic Fijian and/or western/global culture with respect to a range of behaviors and attitudes. In contrast to theoretical models positing uni-dimensional, orthogonal, or oblique relations between cultural identities in individuals undergoing acculturation, our study findings support a heterogeneous pattern among correlations of dimensions across contrasting cultural identities. We suggest multidimensional measures of acculturation are optimal — and socio-demographic proxies inadequate — for characterization of this complex process for health research. PMID:21088103

    PubMed

    2014-12-01

    Iodine is an essential component of the thyroid hormones, which play a crucial role in brain and neurological development. At least one-third of the world's population is estimated to be iodine deficient predominantly in developing countries. Recently concern had also been expressed about the iodine status in industrialised countries such as the UK. A recent survey of the UK iodine status found that that more than two-thirds of schoolgirls aged 14-15 years were iodine deficient due to the reduced milk intake. Maternal iodine deficiency in pregnancy is correlated with cognitive outcomes such as intelligence quotient and reading ability in offspring. No randomised trial data exist for iodine supplementation in mild-moderate iodine-deficient pregnant women. It is possible to combine population interventions to reduce population salt intake with salt iodisation programmes in order to maintain adequate levels of iodine nutrition.

    Second-generation antihistamines are widely prescribed for the control of symptoms of allergic inflammation such as itchy hives, coryza, and itchy eyes. In rare circumstances, these drugs might provoke allergic inflammation. Hypersensitivity to bepotastine besilate, a second-generation antihistamine has never been reported. A 17-year-old schoolgirl, whose paroxysmal itchy hives had been controlled with bepotastine, experienced aggravation of the hives. An oral provocation test confirmed her hypersensitivity to bepotastine and cross-reactivity to levocetirizine. She showed no reaction to chlorpheniramine, ketotifen, or olopatadine among the 13 antihistamines tested. While searching for an antihistamine to control her itchy hives, we found that she also exhibited cross-reactivity to various antihistamines with different chemical structures from that of bepotastine, which is not predicted according to the chemical classification of antihistamines. We report a case of hypersensitivity to bepotastine besilate in a patient with chronic spontaneous urticaria. PMID:27803886

    In recent years, the menstrual hygiene management challenges facing schoolgirls in low-income-country contexts have gained global attention. We applied Gusfield's sociological analysis of the culture of public problems to better understand how this relatively newly recognized public health challenge rose to the level of global public health awareness and action. We similarly applied the conceptualization by Dorfman et al. of the role of public health messaging in changing corporate practice to explore the conceptual frames and the news frames that are being used to shape the perceptions of menstrual hygiene management as an issue of social justice within the context of public health. Important lessons were revealed for getting other public health problems onto the global-, national-, and local-level agendas. PMID:25973831

    Sir Dugald Baird sketches the history of abortion legislation in Great Britain from the beginning of the century. In his views the 1967 Abortion Act has been one of the most important and beneficial pieces of social legislation enacted in Britain in the last 100 years. It has, however, brought problems both of administration in the hospitals and to individual doctors and nurses, particularly when the patients are young single women and even schoolgirls. One of the consequences of the Abortion Act has been a fall in maternal mortality and perinatal mortality rates. Abortion does not seem to be followed by serious emotional sequelae. Nevertheless recent changes in sexual mores have introduced new and serious social problems which are discussed in relation to the role of the doctor in his relationship with patients seeking abortion.

    A questionnaire survey of knowledge, attitudes and beliefs towards menstruation was made in 22 schools in Anand district, Gujarat state. Of 900 schoolgirls aged 11-17 years, only 38.5% felt comfortable about menarche and only 31.0% believed that menstruation was a normal physiological process. Many (37.2%) had not been informed about menarche before its onset and 48.2% felt they were not mentally prepared. The major sources of information were the mother (60.7%) or an elder sister (15.8%); teachers and others relatives played a small role. In this area of India, many families continue the custom of celebrating the first menarche and observing social restrictions.

    The prevention of congenital rubella syndrome (CRS), as a complication of rubella infection during pregnancy, is the main aim of rubella vaccination programmes. However, as vaccination of infants leads to an increase in the average age at which those who were not immunized become infected, certain rubella vaccination programmes can lead to an increase in the incidence of CRS. In this paper we use a mathematical model of the transmission dynamics of rubella virus to investigate the likely impact of different vaccination policies in Europe. The model was able to capture pre- and post-vaccination patterns of infection and prevalence of serological markers under a wide variety of scenarios, suggesting that the model structure and parameter estimates were appropriate. Analytical and numerical results suggest that endemic circulation of rubella is unlikely in Finland, the United Kingdom, The Netherlands, and perhaps Denmark, provided vaccine coverage is uniform across geographical and social groups. In Italy and Germany vaccine coverage in infancy has not been sufficient to interrupt rubella transmission, and continued epidemics of CRS seem probable. It seems unlikely that the immunization programmes in these countries are doing more harm than good, but this may be partly as a result of selective immunization of schoolgirls. Indeed, in both these countries, selective vaccination of schoolgirls with inadequate vaccination histories is likely to be an important mechanism by which CRS incidence is suppressed (unlike the other countries, which have had sufficiently high infant coverage rates to withdraw this option). Reducing inequalities in the uptake of rubella vaccine may bring greater health benefits than increasing the mean level of coverage. PMID:11218213

    The aim of this study was to define processes of orientation and/or selection towards sports game of volleyball in schoolgirls of Kastela, aged 10-12, by examining the relations between regular classes of physical education (PE) and extracurricular sport activities. For this purpose, two morphological measures were used (body height and body mass) and a set of 11 motor tests (6 basic motor abilities tests and 5 motor achievement tests) on a sample of 242 girls aged 10-12 was used, divided into a subsample of 42 girls participating in volleyball training (Volleyball players) and a subsample of 200 girls who do not participate in volleyball training (volleyball non-players). Based on the comparison of test results of schoolgirls from Kastela and Croatian norms, factor analysis of applied variables and discriminant analysis of these variables between volleyball players and non-players, processes and/or phases of selection in forming quality volleyball players were defined. Selection processes are preceded by orientation processes in physical education classes, i.e. choosing those sport activities which are in accordance with the biomotor status of students. Results have shown that orientation and initial selection in female volleyball needs to be executed based on the motor set of psychomotor speed, repetitive strength of the trunk and flexibility (muscle tone regulation), and body height. Volleyball training has affected the muscle mass development and the development of strength factors, so that explosive strength of jumping and/or takeoff along with body height, has predominantly differentiated female volleyball players from non-players, aged 10 to 12, and serve and spike quality will have dominant influence on the match outcome.

    It is a major challenge to bring science and technology to the public at large and more particular to young people. This is even more true for marine sciences, due to the very nature of the study field and the fact that the underwater world is difficult to experience and communicate. Therefore it is not surprising that in Europe there are only few examples of marine educational projects that try to go beyond the ‘observe and describe' approach. In 2004 SHE Consultancy, the Flanders Marine Institute VLIZ and DAB Vloot developed a first Belgian e-learning programme dedicated to oceans and seas, with the support of the Flemish government ("Action plan Science Communication"). This programme ‘Expedition Zeeleeuw' (www.expeditiezeeleeuw.be), ran from 2005 till 2007 and challenged some 3000 Flemish students of 16-18 years old all over Flanders to find creative solutions for 10 major marine issues at the Belgian coast. The class that could convince the jury to have discovered the most creative and intelligent solutions, wan a one-week scientific expedition at sea on board the vessel Zeeleeuw. As a successor to ‘Expedition Zeeleeuw', a new e-learning project on marine science was developed in 2007: ‘Planeet Zee' i.e. ‘Planet Ocean' (www.planeetzee.org; info via info@planeetzee.org + demo-site in English available at www.planetocean.eu). The new marine and coastal e-learning project is presented as a virtual sailing trip on the Atlantic Ocean. It follows the adventures of two youngsters "borrowing" the yacht of their father and getting into trouble on the open ocean. On this journey they face 21 problems (eg. out of food, drinking water or fuel, fear for whales, Bermuda triangle, tsunami's etc… ), each of them introduced by a short movie clip. When they realize they can not solve the problem, they ask for radio help and - what a surprise! - get interesting answers from the Zeeleeuw research vessel and its 21 marine scientists on board, that appears to be in the

    We investigated the impact of vaccination on rubella epidemiology in Australia, using a mathematical model fitted to Australian serosurvey data and incorporating pre-vaccination European estimates of rubella transmissibility. Mass infant measles-mumps-rubella (MMR) vaccination produced a 99% reduction in both rubella and congenital rubella syndrome (CRS) incidence by 2010 compared to the pre-vaccination era (1960-70). The model is consistent with reductions in CRS based on surveillance of congenital hearing impairment. Model simulations suggest that selective schoolgirl vaccination (1971-88) was associated with a 90% reduction in CRS incidence, but only a 1-4% reduction in rubella incidence. Our model predicted that these reductions in rubella were much less vulnerable to reductions in MMR vaccine coverage than for measles. In the future, a less than 15% decrease in MMR vaccine coverage is estimated to have minimal impact before 2060, but a 20% reduction may result in a 7-fold increase in rubella incidence, with the effective reproductive number R rising from 0.28 to 0.78 by 2060. The 99% reduction in both rubella and CRS incidence and low effective reproductive number (R≤0.28) we documented after 2010 are consistent with Australia having achieved rubella elimination.

    Selective rubella vaccination of schoolgirls commenced in 1971 and was followed by a significant reduction in congenital rubella. Infant vaccination with MMR was introduced in 1989 to interrupt circulation of the virus in young children, and in 1994/95 the adolescent school based rubella vaccination program was changed to MMR for both boys and girls. This report reviews the epidemiology of rubella and congenital rubella between 1992 and 1997 using reports to the National Notifiable Diseases Surveillance System (NNDSS) and the Australian Paediatric Surveillance Unit (APSU). Notification rates for rubella exceeded 20 per 100,000 in 1992, 1993 and 1995 and declined to 7.2 per 100,000 in 1997. Sixty-one per cent of notifications occurred between September and December and 68% occurred in males. The incidence rate in males aged 15-22 years peaked at 152.6 per 100,000 in 1995 reflecting the lack of immunisation in this cohort. From 1993 to 1997, 19 children were reported with congenital rubella syndrome, representing 1 in 67,000 live births. Of these, 17 had multiple defects (4 died) and 2 had deafness only. There were also 5 infants with congenital rubella infection but no defects. Australia's rate of congenital rubella syndrome exceeded that of the United Kingdom and the United States of America but this may be partly attributable to differences in reporting practices. The impact of changing the second dose of MMR vaccine to 4 years of age in 1998 will require careful monitoring.

  15. The Paradigm Shift to Non-Treatment of Asymptomatic Bacteriuria

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

    In 1995-96 we conducted a review of rubella immunization strategies. Worldwide, 78 countries (more than one-third) reported a national policy of using rubella vaccine. This was closely related to country economic status. Based on the United Nations country classification, rubella vaccine is used in 92% of industrialized countries, 36% of those with economies-in-transition, and 28% of developing countries. Cases of congenital rubella syndrome (CRS) may be prevented as follows: by providing direct protection to women and/or schoolgirls (a selective vaccination strategy); by vaccinating boys and girls to provide indirect protection by reducing the transmission of rubella virus (a childhood vaccination strategy); or by a combination of these approaches (a combined strategy). A combined strategy was most commonly reported (60% of countries); seven countries (9%) reported a selective strategy; and 24 countries (31%) reported only childhood immunization. Experience has shown that it is essential to include vaccination of women of childbearing age in any rubella control strategy. Childhood vaccination alone may pose a risk of an increase in CRS cases. Although many countries have introduced rubella vaccine, few report any data on the impact of vaccination. Countries using rubella vaccine need to establish surveillance for rubella and CRS and monitor coverage in each of the target groups. PMID:9141752

    Recent evidence suggests that conditional cash transfer (CCT) programs for schooling are effective in raising school enrollment and attendance. However, there is also reason to believe that such programs can affect other outcomes, such as the sexual behavior of their young beneficiaries. Zomba Cash Transfer Program is a randomized ongoing CCT intervention targeting young women in Malawi that provides incentives (in the form of school fees and cash transfers) to current schoolgirls and recent dropouts to stay in or return to school. An average offer of US$10/month conditional on satisfactory school attendance - plus direct payment of secondary school fees - led to significant declines in early marriage, teenage pregnancy, and self-reported sexual activity among program beneficiaries after just one year of program implementation. For program beneficiaries who were out of school at baseline, the probability of getting married and becoming pregnant declined by more than 40 and 30%, respectively. In addition, the incidence of the onset of sexual activity was 38% lower among all program beneficiaries than the control group. Overall, these results suggest that CCT programs not only serve as useful tools for improving school attendance but may also reduce sexual activity, teen pregnancy, and early marriage.

    In Spain, vaccination against rubella was initiated in schoolgirls in the mid-1970s. In Gipuzkoa, subsequent extensions to the vaccination schedule culminated in 1992 with the introduction of the two-dose measles, mumps and rubella vaccine in children and adolescents of both sexes. Moreover, in 1985 a programme for the identification and vaccination of non-immune parturient women was implemented in the region's main hospital. The prevalence of rubella-susceptible parturient women decreased from 3.7 % at the beginning of the study to < 1.5 % by 1992. Despite this overall decrease, 4.8 % of adolescent parturients were susceptible to rubella during 2001--2002. From 1984, the number of reported cases of rubella (children and adults) progressively decreased until 1997, after which there have been no cases of indigenous rubella. There have been no cases of reported congenital rubella since 1984. These results indicate that the vaccine policy carried out in this geographical area has been effective in achieving considerable progress towards rubella elimination. PMID:15310170

    From 2008 to 2011, schoolgirls were vaccinated against HPV in two districts in Uganda following sensitization. This study assessed girls’ knowledge of cervical cancer and HPV vaccine, and their acceptance of future vaccination of friends and hypothetical daughters. The cross-sectional, mixed methods comparative study was conducted in two districts. Univariate, bivariate, logistic regression and thematic analyses were done. HPV vaccination was positively associated with knowledge (Crude OR: 5.31, CI: 3.19–8.86; p = 0.000); but knowledge (Adjusted OR: 1.13, CI: 0.56–2.28; p = 0.73) and HPV vaccination (Adjusted OR: 0.92, CI: 0.16–5.36; p = 0.93) did not predict vaccine acceptability. Seemingly important motivations for vaccine acceptance were: its role in cancer prevention and advancement of reproductive health, minimal side effects, and positive peer role models. Major deterrents to vaccine acceptance were: rumours and misconceptions about possible side effects, perceived inadequate information about vaccine, and fear of side effects. PMID:25854092

    The region encompassing Australasia and Oceania, including Australia, New Zealand, Fiji and Papua New Guinea, is a diverse one with respect to ethnicities, cultures and behaviours. It includes countries with comprehensive cervical cytology screening programmes which can be credited with significant reductions in cervical cancer incidence and mortality, and countries with no prevention programmes and significantly higher incidence and mortality. As elsewhere in the world, human papillomavirus (HPV)-16 and 18 are the commonest high-risk types, with the highest rates in women under 25 years of age. These two high-risk HPV types are found most frequently in cervical cancers and high-grade dysplasias, although there are minimal data for many countries in Oceania. In April 2007, Australia became the first country worldwide to commence a government funded universal HPV vaccine programme. The school-based programme targets 12-year old females in an ongoing schedule, with a catch-up programme up to 26 years of age, to be completed in mid-2009. Vaccine introduction has been comprehensively rolled out, with around 75% uptake of the complete vaccine schedule among school-girls in the first year of this initiative. This represents a successful model for other countries. We present data on cervical cancer, risk factors and prevention strategies, including epidemiology of HPV and HPV vaccine strategies.

    Background Previous efforts to derive empirically based eating disorder (ED) typologies through latent structure modeling have been limited by ethnic and cultural homogeneity of their study populations and their reliance on DSM-IV ED signs and symptoms as indicator variables. Methods Ethnic Fijian schoolgirls (N = 523) responded to a self-report battery assessing ED symptoms, herbal purgative use, comorbid psychopathology, clinical impairment, cultural orientation, and peer influences. Participants who endorsed self-induced vomiting or herbal purgative use in the past 28 days (n = 222) were included in a latent profile analysis (LPA) to identify unique subgroups of bulimic symptomatology. Results LPA identified a bulimia nervosa (BN)-like class (n = 86) characterized by high rates of binge eating and self-induced vomiting; and an herbal purgative class (n = 136) characterized primarily by the use of indigenous Fijian herbal purgatives. Both ED classes endorsed greater eating pathology and general psychopathology than non-purging participants, and the herbal purgative class endorsed greater clinical impairment than either BN-like or non-purging participants. Cultural orientation did not differ between the two ED classes. Conclusions The inclusion of study populations underrepresented in mental health research and broadening the scope of relevant signs and symptoms in latent structure models may increase the generalizeability of ED nosological schemes to encompass greater cultural diversity.

    Data on menstrual experiences and their impact on quality of life among women in developing countries are scant. The aim of this study was to assess the prevalence of dysmenorrhoea among adolescent girls in Sidon city and suburbs, Lebanon, and to explore its possible relationship with menstrual experience. In a cross-sectional design, 389 post-menarcheal schoolgirls aged 13-19 years were selected using a cluster random sampling method. Of these 161 (41.4%) were regularly or sometimes absent from school due to menstrual problems and 289 (74.3%) experienced dysmenorrhoea. Nevertheless only 7.3% of the girls had consulted a physician about dysmenorrhoea. Three-quarters of these young women (75.2%) had scores indicating negative menstrual experience based on the Menstrual Experience and Behavior Questionnaire. Significant predictors of dysmenorrhoea were negative menstrual experience, younger age of girl, longer duration of bleeding and longer cycle length. Better reproductive health educational programmes focusing on menstruation are needed for female adolescents.

    Ireland's prohibition of abortion has been fiercely enforced by conservative anti-abortion activists in organizations such as the Society for the Protection of the Unborn Child. The Society succeeded in getting the Irish High Court to rule in 1987 that any discussion of abortion or referral to England for legal abortion services on the part of women's health and student groups constituted a violation of the constitutionally protected right to life of the fetus. Supporters of abortion rights were forced further underground and isolated from their constituency--poor women without information or funds. This censorship has not decreased the number of Irish women who travel to England for legal abortion; an average of 400 women/year give Irish addresses at UK clinics and another 4000 probably give a false UK address. Thus, England has been placed in the position of assuming responsibility for what is an Irish social problem. However, the case of a 14-year-old girl who sought to travel to England to abort a pregnancy resulting from rape has forced the Irish Government to confront its hypocrisy. Initially, it was ruled that the schoolgirl must continue the pregnancy, despite her threats of suicide. Massive public outcry resulted in a reversal of this decision, and the European Court of Human Rights found Ireland's abortion information ban in contravention of human rights. The ban has since been reversed through public referendum, and there are some indications that abortions to save the life or health of the mother may be legalized.

    The aim of this study was to generate a theoretical model of underlying social processes that trigger stress in adolescent girls' everyday life. In-depth interviews regarding the experiences of stress at home, school and during leisure time were conducted with 14 17-year-old schoolgirls. Data were analysed by means of the grounded theory method. Stress was triggered in the interaction between responsibility and the way in which the girls were encountered. Triggered emotional reactions took the form of four dimensions of stress included ambivalence, frustration, despair and downheartedness. These reactions were dependent on whether the girls voluntary assumed responsibility for various situations or whether they were forced, or felt they were being forced, to assume responsibility in interaction with an encounter characterized by closeness or distance. These forms of stress reactions could appear in one dimension and subsequently shift to another. From the public health perspective, the generated stress model can be used in the planning and implementation of future actions to prevent stress and promote well-being related to stress in adolescent girls.

    A total of 462 schoolgirls aged 7-8 and 17-18 years were examined anthropometrically (45 body measurements and 10 skinfolds) in a cross-sectional study. The data were processed in two age groups: 7-8-year-olds (n = 205) and 17-18-year-olds (n = 257). Relying on average height and weight in the groups, both groups were divided into five body build classes: small, medium, large, pyknomorphous and leptomorphous. In these classes, the differences in all other body measurements were compared, and in both age groups, analogous systematic differences were found in length, width and depth measurements and circumferences. This enabled us to compare proportional changes in body measurements during ten years, using for this ratios of averages of basic measurements and measurement groups in the same body build classes. Statistical analysis by the sign test revealed statistically significant differences between various body build classes in the growth of averages. Girls belonging to the small class differed from the girls of the large class by an essentially greater increase in their measurements. Our results suggest that the growth rate of body measurements of girls with different body build can be studied by the help of body build classification.

    In South Africa (SA), >4,000 women die annually of cervical cancer, a disease caused by the human papillomavirus (HPV). Infections caused by certain genotypes of HPV increase the risk of cervical cancer. HIV-infected women in particular are more likely to have persistent HPV infection, with higher-risk genotypes. In SA, two vaccines (HPV quadrivalent (types 6, 11, 16, and 18) vaccine, recombinant (Gardasil) and HPV bivalent (types 16 and 18) vaccine, recombinant (Cervarix)) are currently registered for the prevention of HPV-related disease. In the past, there have been significant challenges to achieving high coverage and uptake of vaccination–contributory factors include cost and lack of awareness. An HPV demonstration project among schoolgirls in rural KwaZulu-Natal showed that high vaccine uptake is achievable. In 2014, the National Department of Health launched the national HPV vaccination programme among female learners attending public schools. Awareness of HPV vaccination among healthcare providers, education of parents, teachers and learners, and avoidance of missed opportunities for vaccination are vital to the success of the programme. Primary healthcare practitioners may play an important role in cervical cancer prevention by identifying and offering vaccination to girls who miss the opportunity to be vaccinated at school. HPV vaccination should be considered as one arm of a comprehensive programme of cervical cancer prevention and control. PMID:26937512

    Although the effect of stereotype threat concerning women and mathematics has been subject to various systematic reviews, none of them have been performed on the sub-population of children and adolescents. In this meta-analysis we estimated the effects of stereotype threat on performance of girls on math, science and spatial skills (MSSS) tests. Moreover, we studied publication bias and four moderators: test difficulty, presence of boys, gender equality within countries, and the type of control group that was used in the studies. We selected study samples when the study included girls, samples had a mean age below 18years, the design was (quasi-)experimental, the stereotype threat manipulation was administered between-subjects, and the dependent variable was a MSSS test related to a gender stereotype favoring boys. To analyze the 47 effect sizes, we used random effects and mixed effects models. The estimated mean effect size equaled -0.22 and significantly differed from 0. None of the moderator variables was significant; however, there were several signs for the presence of publication bias. We conclude that publication bias might seriously distort the literature on the effects of stereotype threat among schoolgirls. We propose a large replication study to provide a less biased effect size estimate.

    Exciting Week Ahead for Winners of Unique Astronomy Contest Following the very successful events of 1993 and 1994 [1], ESO again opens its doors for an `educational adventure' next week. It takes place within the framework of the `Third European Week for Scientific and Technological Culture', initiated and supported by the European Commission. On Tuesday, November 14, 1995, about forty 16-18 year old students and their teachers will converge towards Munich from all corners of Europe. They are the happy winners of a Europe-wide astronomy contest (`Europe Towards the Stars') that took place during the summer and early autumn. Their prize is a free, week-long stay at the Headquarters of the European Southern Observatory. During this time they will work with professional astronomers and get a hands-on experience within modern astronomy and astrophysics at one of the world's foremost international centres. In particular, the participants will be exposed to the scientific method by carrying through a research programme of their own, all the way from conception to interpretation of the data. The culmination of the stay will be the opportunity to perform remote observations via a satellite link with two major telescopes at the ESO La Silla observatory in Chile, including the very advanced 3.5-metre New Technology Telescope (NTT). The European Contest This year's EU/ESO programme was devised as a contest between joint teams of secondary school students and their teachers. The teams had to choose between four different subjects requiring either practical or theoretical work, and all with strong scientific and technological components. One subject was to devise an observational programme with an existing telescope and instrument and to discuss the resulting data in order to arrive at a scientific conclusion. This was the preferred subject by many teams. For instance, the winning German team observed the moons of Jupiter and the Danish team studied a star cluster in order to

    Constant change is here to stay Curriculum change was a major theme in the workshops of Physics On Stage - the Europe-wide meeting of physics teachers hosted at CERN in November. And, human nature being what it is, we all want to manage this change. There are many issues of ownership, consultation and management to consider when undertaking change, but there are a few basic laws we can follow: You can't please everybody all the time. Trying to do so is a recipe for displeasing everybody. If you really want to see the effect of a change you can only change one thing at a time; So if you change too many things at once you can't possibly predict the outcome. But education is so full of so many changes that making a prediction as to how well a curriculum change will work makes weather-forecasting look easy. There are few countries where some kind of educational reform is not taking place. The UK education system is currently coping with over 100 different initiatives. The reform of the post-16 pre-university curriculum into one-year courses (including AS and A2 exams which replace A-levels) is just one of many changes. A recent request for a reference had me dusting off some of the earliest copies of Physics Education from the late sixties and early seventies. It was fascinating to note that curriculum change was probably just as much an issue then as now. Mixed-ability, comprehensive and Nuffield-style education were happening. And we were beginning to ask the question `Computers - will we be using them in Physics classes?' It left me wondering: in thirty years, have we made any real progress in the teaching of physics? Is it better than it was? In this issue of Physics Education we take stock of the changes for 16-18 year-olds in UK schools. Whilst many may question the progress made in physics education over the last thirty years, few can doubt the massive leaps of knowledge made through astronomy and planetary science. 2001 may not have turned out as the 1960s

    The traveler participated in ongoing laboratory experiments on the effects of ozone on Co{sub 2} assimilation by bean plants, providing advice on experimental procedures, assistance with data analysis, and access to current literature. He presented a seminar in which the importance of research on elevated CO{sub 2} and global climate change was emphasized because these are areas of major emphasis at Oak Ridge National Laboratory in which international collaboration would be especially beneficial. The most promising area for future collaboration was identified as the integration of experimental research with a tree growth model developed at Tartu University.

    Biology-related indicators do not usually depend on just one meteorological element but on a combination of several weather indicators. One way to establish such integral indicators is to classify the general atmospheric circulation into a small number of circulation types. The aim of present study is to analyse connections between general atmospheric circulation and potato crop yield in Estonia. Meteorologically possible yield (MPY), calculated by the model POMOD, is used to characterise potato crop yield. Data of three meteorological stations and the biological parameters of two potato sorts were applied to the model, and 73 different classifications of atmospheric circulation from catalogue 1.2 of COST 733, domain 05 are used to qualify circulation conditions. Correlation analysis showed that there is at least one circulation type in each of the classifications with at least one statistically significant (99%) correlation with potato crop yield, whether in Kuressaare, Tallinn or Tartu. However, no classifications with circulation types correlating with MPY in all three stations at the same time were revealed. Circulation types inducing a decrease in the potato crop yield are more clearly represented. Clear differences occurred between the observed geographical locations as well as between the seasons: derived from the number of significant circulation types, summer and Kuressaare stand out. Of potato varieties, late 'Anti' is more influenced by circulation. Analysis of MSLP maps of circulation types revealed that the seaside stations (Tallinn, Kuressaare) suffer from negative effects of anti-cyclonic conditions (drought), while Tartu suffers from the cyclonic activity (excessive water).

    Soil monitoring networks provide a powerful base for estimating and predicting nation's soil status in many aspects. The datasets of soil monitoring are often hierarchically structured demanding sophisticated data analyzing methods. The National Soil Monitoring of Estonia was based on a hierarchical data sampling scheme as each of the monitoring site was divided into four transects with 10 sampling points on each transect. We hypothesized that the hierarchical structure in Estonian Soil Monitoring network data requires a multi-level mixed model approach to achieve good prediction accuracy of soil properties. We used this database to predict soil bulk density and soil organic carbon concentration of mineral soils in arable land using different statistical methods: median approach, linear regression and mixed model; additionally, random forests for SOC concentration. We compared the prediction results and selected the model with the best prediction accuracy to estimate soil organic carbon stock. The mixed model approach achieved the best prediction accuracy in both soil organic carbon (RMSE 0.22%) and bulk density (RMSE 0.09 g cm-3) prediction. Other considered methods under- or overestimated higher and lower values of soil parameters. Thus, using these predictions we calculated the soil organic carbon stock of mineral arable soils and applied the model to a specific case of Tartu County in Estonia. Average estimated SOC stock of Tartu County is 54.8 t C ha-1 and total topsoil SOC stock 1.8 Tg in humus horizon.

    The International Conference Functional Materials and Nanotechnologies (FM&NT - 2013) was held in Tartu, 21-24 April 2013 at the Dorpat Conference Centre. The conference was organised by Institute of Physics, University of Tartu. The FM&NT conference series was started in 2006 by scientists from the Institute of Solid State Physics, University of Latvia. It is an annual conference bringing together researchers from the whole world. The warm and open atmosphere of this scientific conference has turned it into event where people from different fields meet under the common name of functional materials and nanotechnology. It is particularly important for early stage scientists who are looking for new knowledge and contact with people from various fields. Our Latvian colleagues with their success in internationalization made us neighbouring Estonians so envious that we could not withstand proposing that we host the conference in every second year in Estonia. Actually this is in a way the continuation of the idea of the famous Baltic seminars which took place over several decades during the last century. Due to political constraints these seminars were only opened to scientist of the former Eastern European countries, but which were extremely popular and attracted attendees from over the whole Soviet Union. Much fruitful cooperation started from the initial personal contacts of scientists at these seminars held twice per year, once in Latvia and the second time in Estonia. At the last FM&NT 2012 conference, the decision was made that Institute of Physics, University of Tartu would organise the event in Tartu in 2013. Along with traditional topics such as multifunctional materials, nanomaterials, materials for sustainable energy applications and theory, this conference focused on studies using synchrotron radiation and other novel light sources. The number of registered participants from 21 countries was nearly 300. During the three days of the conference 14 invited, 45

    Introduction Harmful gender norms and inequalities, including gender-based violence, are important structural barriers to effective HIV programming. We assess current evidence on what forms of gender-responsive intervention may enhance the effectiveness of basic HIV programmes and be cost-effective. Methods Effective intervention models were identified from an existing evidence review (“what works for women”). Based on this, we conducted a systematic review of published and grey literature on the costs and cost-effectiveness of each intervention identified. Where possible, we compared incremental costs and effects. Results Our effectiveness search identified 36 publications, reporting on the effectiveness of 22 HIV interventions with a gender focus. Of these, 11 types of interventions had a corresponding/comparable costing or cost-effectiveness study. The findings suggest that couple counselling for the prevention of vertical transmission; gender empowerment, community mobilization, and female condom promotion for female sex workers; expanded female condom distribution for the general population; and post-exposure HIV prophylaxis for rape survivors are cost-effective HIV interventions. Cash transfers for schoolgirls and school support for orphan girls may also be cost-effective in generalized epidemic settings. Conclusions There has been limited research to assess the cost-effectiveness of interventions that seek to address women's needs and transform harmful gender norms. Our review identified several promising, cost-effective interventions that merit consideration as critical enablers in HIV investment approaches, as well as highlight that broader gender and development interventions can have positive HIV impacts. By no means an exhaustive package, these represent a first set of interventions to be included in the investment framework. PMID:25373519

  16. A review of the iodine status of UK pregnant women and its implications for the offspring

    Iodine, as a component of the thyroid hormones, is crucial for brain development and is therefore especially important during pregnancy when the brain is developing most rapidly. While randomised controlled trials of pregnant women in regions of severe iodine deficiency have shown that prenatal iodine deficiency causes impaired cognition, less is known of the effects in regions of mild deficiency. This is relevant to the UK as the World Health Organisation now classifies the UK as mildly iodine deficient, based on a national study of 14-15 year old schoolgirls in 2011. We have previously published a study, using samples and data from the UK-based Avon Longitudinal Study of Parents and Children (ALSPAC) that found an association between low iodine status in early pregnancy (urinary iodine-to-creatinine ratio < 150 μg/g) and lower verbal IQ and reading scores in the offspring. Though the women in ALSPAC were recruited in the early 1990s, the results of the study are still relevant as their iodine status was similar to that reported in recent studies of UK pregnant women. This review discusses the evidence that mild-to-moderate iodine deficiency during pregnancy has deleterious effects on child neurodevelopment and relates that evidence to the data on iodine status in the UK. It has highlighted a need for nationwide data on iodine status of pregnant women and that a randomised controlled trial of iodine supplementation in pregnant women in a region of mild-to-moderate iodine deficiency with child outcomes as the primary endpoint is required.

    Serum levels of the gonadal hormones inhibin A and inhibin B are undetectable or low in prepubertal girls, and rise during puberty. In girls with central precocious puberty (CPP) the hypothalamic-pituitary-gonadal axis is prematurely activated, if the girl is thereafter treated with GnRH agonists both gonadotropins and estradiol levels become suppressed. We therefore investigated serum levels of inhibin A and inhibin B in girls with CPP at diagnosis and during treatment in order to test the hypothesis that inhibin secretion would increase and decrease in parallel with the activation and suppression of the hypothalamic-pituitary-gonadal axis. Serum levels of inhibin A and inhibin B were significantly (p < 0.0005) elevated in 42 girls at diagnosis of CPP (inhibin A: 7 pg/ml (<7--139), inhibin B: 80 pg/ml (<20--294) (median, range)) compared to levels in age-matched healthy schoolgirls (inhibin A: all values <7 pg/ml, inhibin B: 21 pg/ml (<20--122) (median, range)), but were appropriate for Tanner stage. During treatment with GnRH agonist (intranasal buserelin and oral cyproterone acetate, treatment group 1, n = 23, or triptorelin depot injections, treatment group 2, n = 19) levels of both hormones fell significantly (p = 0.002). There was a significantly (p = 0.003) greater fall in inhibin B levels during treatment in group 2 compared to group 1, with inhibin B levels now lying below (group 2: <20 pg/ml (<20--68)) rather than within (group 1: 34.5 pg/ml (<20--93)) the age-appropriate range. It is concluded that levels of inhibin A and inhibin B are elevated and suppressed in concert with activation and suppression of the hypothalamo-pituitary-gonadal axis in girls with CPP, supporting the concept that ovarian inhibin secretion is dynamically regulated by gonadotropin stimulation.

    In September 2008, the human papillomavirus (HPV) immunisation programme was introduced in the UK for schoolgirls aged between 12 and 18 years of age. The vaccine shows high efficacy in preventing infection against HPV types 16 and 18 responsible for 70% of cervical cancer. However, to be most effective, the vaccine needs to be administered before exposure to the viruses and therefore, ideally, before young people become sexually active. The introduction of any new vaccine, and perhaps particularly one given to young teenage girls to prevent a sexually transmitted cancer-causing virus, has the potential to attract a great deal of media attention. This paper reports on content analysis of 344 articles published between January 2005 and December 2008 in 15 UK newspapers. It includes both manifest and latent analysis to examine newsprint media coverage of the introduction of the HPV vaccination programme and its role in HPV advocacy. We concluded that the newspapers were generally positive towards the new HPV vaccination and that over the 4 years period the newsworthiness of the HPV vaccination programme increased. In 2008 two events dominated coverage, firstly, the introduction of the HPV programme in September 2008 and secondly, in August 2008 the diagnosis on camera of cervical cancer given to Jade Goody, a 27 year old mother of two, who gained fame and notoriety in the UK through her participation in several reality television shows. There are two conclusions from this study. Firstly, the positive media coverage surrounding the introduction of the HPV vaccination programme is to be welcomed as it is likely to contribute towards influencing public perceptions about the acceptability and need for HPV vaccination. Secondly, the focus on prevalence rates of HPV infection among women and on women's sexual behaviours, in relation to HPV vaccination 'encouraging' promiscuity, is an unhelpful aspect of media coverage.

    A group of women formed the Women and AIDS Support Network (WASN) in Zimbabwe in June 1989 to improve women;s self-esteem and confidence and to bring about changes in attitudes and reactions toward AIDS-related problems. Both HIV-positive and HIV-negative women are WASN members. Women have limited control over sexual relationships. Women who know their partners are having intercourse with other women have few options, e.g., they may depend on their partners. A family council settles marital disagreements, but husbands do not always cooperate. Increased peer pressure could change societal acceptance of male infidelity to positive attitudes toward friendship and partnership in marriage. Therefore, WASN explores sexual relationships, especially control and power in them. These discussions should lead to affirmation of positive behavior. For example, men can promote condom use and monogamy to their male peers. They can also talk to their partners and their sons about HIV. Rural women should not blame urban women for their partner's HIV status. WASN also targets schoolgirls. Most early and some current messages of AIDS campaigns reinforces the dichotomy of good and bad women, supported by an earlier link between urban women and sexually transmitted diseases. Yet, they ignored men's role in HIV transmission. WASN speaks out against such negative images, e.g., dramas that depict the HIV-infected woman as evil and the innocent as good while the man worries about which woman infected him instead of feeling awful about infecting other women. WASN also addressee AIDS-related discrimination on the job and stigmatization issues. It now is conducting 2 research projects: information needs of urban and rural women and capacities of family support systems to assist HIV-positive women.

  20. Age at menarche and its relationship to body mass index among adolescent girls in Kuwait

    2013-01-01

    Background Despite the increasing rates of childhood obesity and rapid change in socio-economic status, the mean age at menarche remains mostly unknown among contemporary girls in Kuwait and other countries in the Gulf region. This study aimed to estimate the mean age at menarche among schoolgirls in Kuwait and investigate the association between age at menarche and obesity. Methods A cross-sectional study was conducted on 1,273 randomly selected female high school students from all governorates in Kuwait. Overweight was defined as higher than or equal to the 85th percentile and obesity as higher than or equal to the 95th percentile using growth charts provided by the Centres for Disease Control and Prevention (CDC, 2000). Data on menarche, socio-demographic status, physical activity and diet were collected using confidential self-administered questionnaire. Results Out of 1,273 students, 23 (1.8%) were absent or refused to participate. The mean age at menarche was 12.41 years (95% CI: 12.35-12.48). The prevalence of early menarche, defined as less than 11 years of age, was 8.5% (95% CI: 7.0-10.2%). The prevalence of obesity and overweight was 18.3% (95% CI: 16.2-20.6%) and 25.8% (95% CI: 23.42-28.30%), respectively. Age at menarche was inversely and significantly associated with odds of overweight and obesity after adjusting for potential confounders, odds ratio 0.84 (0.77-0.93); (p = 0.001). Conclusion Age at menarche among contemporary girls in Kuwait is similar to that in industrialized countries. There is an inverse association between age at menarche and obesity or overweight. Trends in menarcheal age should be monitored and time of sexual maturation and its related factors should be taken into account in strategies that aim to combat obesity. PMID:23311596

    Background As human papillomavirus (HPV) vaccines become available in developing countries, acceptability studies can help to better understand potential barriers and facilitators of HPV vaccination and guide immunisation programs. Methods Prior to a cluster-randomised phase IV trial of HPV vaccination delivery strategies in Mwanza Region, Tanzania, qualitative research was conducted to assess attitudes and knowledge about cervical cancer and HPV, and acceptability of and potential barriers to HPV vaccination of Tanzanian primary schoolgirls. Semi-structured interviews (n = 31) and group discussions (n = 12) were conducted with a total of 169 respondents (parents, female pupils, teachers, health workers and religious leaders). Results While participants had heard of cancer in general, most respondents had no knowledge of cervical cancer, HPV, or HPV vaccines. Only health workers had heard of cervical cancer but very few knew its cause or had any awareness about HPV vaccines. After participants were provided with information about cervical cancer and HPV vaccination, the majority stated that they would support HPV vaccination of their daughter to protect them against cervical cancer. Opt-out consent for vaccination was considered acceptable. Most preferred age-based vaccination, saying this would target more girls before sexual debut than class-based vaccination. Potential side effects and infertility concerns were raised by 5/14 of participating male teachers. Discussion Reported acceptability of HPV vaccination amongst parents, teachers and other community members was high in this population. Respondents stressed the need to provide adequate information about the vaccine to parents, that also addresses side effects and infertility concerns. PMID:22732428

    Recent dietary guidelines emphasize micronutrient sufficiency by giving importance to consumption of whole grains and a variety of fruits and vegetables. The objective of this study was to identify a measure of micronutrient quality of diets in adolescent girls consuming a lacto-vegetarian diet. Data were collected on the nutritional status of 630 schoolgirls (ages 10 to 16 years) from Pune city, India, in a cross-sectional survey during 2006-2007. Dietary intakes were assessed by 24-hour recall on 3 nonconsecutive days. Nutrient intakes were calculated from the Indian nutritive value databases. Micronutrient adequacy was expressed as a ratio of observed intake to reference intake. An Adolescent Micronutrient Quality Index (AMQI) was formulated using the Indian and the recent US dietary guidelines. Fasting blood samples were analyzed for plasma levels of vitamin C, beta carotene, and zinc. The average energy intake of the majority of the girls was below the Indian recommended dietary intakes, whereas micronutrient intakes were 50% to 70% lower than recommended dietary intakes. The mean AMQI score was 41.5+/-9.4. The age of subjects as well as mother's education and occupation were significantly associated with the AMQI. The AMQI was correlated with nutrient intakes and the ratio of observed intake to reference intake (P<0.01) after controlling for energy intake and sociodemographic factors. Higher AMQI scores were associated with higher concentrations of plasma vitamin C (r=0.26), beta carotene (r=0.34), and zinc (r=0.12). The AMQI is a useful measure of the dietary adequacy and micronutrient quality of the diets of adolescent girls consuming lacto-vegetarian diets.

    Ireland's prohibition of abortion has been fiercely enforced by conservative anti-abortion activists in organizations such as the Society for the Protection of the Unborn Child. The Society succeeded in getting the Irish High Court to rule in 1987 that any discussion of abortion or referral to England for legal abortion services on the part of women's health and student groups constituted a violation of the constitutionally protected right to life of the fetus. Supporters of abortion rights were forced further underground and isolated from their constituency--poor women without information or funds. This censorship has not decreased the number of Irish women who travel to England for legal abortion; an average of 400 women/year give Irish addresses at UK clinics and another 4000 probably give a false UK address. Thus, England has been placed in the position of assuming responsibility for what is an Irish social problem. However, the case of a 14-year-old girl who sought to travel to England to abort a pregnancy resulting from rape has forced the Irish Government to confront its hypocrisy. Initially, it was ruled that the schoolgirl must continue the pregnancy, despite her threats of suicide. Massive public outcry resulted in a reversal of this decision, and the European Court of Human Rights found Ireland's abortion information ban in contravention of human rights. The ban has since been reversed through public referendum, and there are some indications that abortions to save the life or health of the mother may be legalized. PMID:12345318

    Background Exposure to alcohol outlets may influence sexual health outcomes at the individual- and community-level. Visiting alcohol outlets facilitates alcohol consumption and exposes patrons to a risky environment and network of potential partners, while presence of alcohol outlets in the community may shift social acceptance of riskier behavior. We hypothesize that living in communities with more alcohol outlets is associated with increased sexual risk. Methods We performed a cross-sectional analysis in a sample of 2,174 South African schoolgirls (ages 13–21) living across 24 villages in the rural Agincourt sub-district, underpinned by long-term health and socio-demographic surveillance. To examine the association between number of alcohol outlets in village of residence and individual-level prevalent HSV-2 infection, we used generalized estimating equations with logit links, adjusting for individual- and village-level covariates. Results The median number of alcohol outlets per village was three (range zero to seven). HSV-2 prevalence increased from villages with no outlets [1.4%, (95% CI: 0.2, 12.1)], to villages with one to four outlets [4.5% (3.7, 5.5)], to villages with more than four outlets [6.3% (5.6, 7.1)]. An increase of one alcohol outlet per village was associated with an 11% increase in odds of HSV-2 infection [adjusted odds ratio (95% CI): 1.11 (0.98, 1.25)]. Conclusions Living in villages with more alcohol outlets was associated with increased prevalence of HSV-2 infection in young women. Structural interventions and sexual health screenings targeting villages with extensive alcohol outlet environments could help prevent the spread of sexually transmitted infections. PMID:25868138

    OBJECTIVE: To investigate the anthropometric and physical performance characteristics of New Zealand rugby players of different ages and both sexes. METHODS: 356 rugby players (264 male, 92 female) took part in the study during a single season. Playing grade ranged from schoolboys and schoolgirls to senior men and women. Assessment of height, weight, neck circumference, and somatotype was performed before the competitive rugby season. A battery of six physical performance assessments was completed after the anthropometry. Analysis of variance was used to examine differences in these variables between field positions and grades. RESULTS: Significant differences between forwards and backs on anthropometric and physical performance variables were apparent at all grades assessed. In terms of anthropometric characteristics, forwards of a given grade were generally taller, possessed greater body mass, and were more endomorphic and less ectomorphic than backs of the same grade. The backs tended to perform better on physical performance measures than forwards, being more aerobically fit, faster, more agile, and possessing a higher degree of muscular endurance. Differences in anthropometry and physical performance attributes were also apparent between players from the various grades. The players at higher levels were generally larger, and performed better on tests of physical performance than the players at lower levels. These differences were found in both sexes. CONCLUSIONS: The greater body mass of the forwards allows them to obtain greater momentum than the backs when sprinting.

    The last decades evidenced auditory laterality in vertebrates, offering new important insights for the understanding of the origin of human language. Factors such as the social (e.g. specificity, familiarity) and emotional value of sounds have been proved to influence hemispheric specialization. However, little is known about the crossed effect of these two factors in animals. In addition, human-animal comparative studies, using the same methodology, are rare. In our study, we adapted the head turn paradigm, a widely used non invasive method, on 8-9-year-old schoolgirls and on adult female Campbell's monkeys, by focusing on head and/or eye orientations in response to sound playbacks. We broadcast communicative signals (monkeys: calls, humans: speech) emitted by familiar individuals presenting distinct degrees of social value (female monkeys: conspecific group members vs heterospecific neighbours, human girls: from the same vs different classroom) and emotional value (monkeys: contact vs threat calls; humans: friendly vs aggressive intonation). We evidenced a crossed-categorical effect of social and emotional values in both species since only "negative" voices from same class/group members elicited a significant auditory laterality (Wilcoxon tests: monkeys, T = 0 p = 0.03; girls: T = 4.5 p = 0.03). Moreover, we found differences between species as a left and right hemisphere preference was found respectively in humans and monkeys. Furthermore while monkeys almost exclusively responded by turning their head, girls sometimes also just moved their eyes. This study supports theories defending differential roles played by the two hemispheres in primates' auditory laterality and evidenced that more systematic species comparisons are needed before raising evolutionary scenario. Moreover, the choice of sound stimuli and behavioural measures in such studies should be the focus of careful attention.

    Iodine, as a component of the thyroid hormones, is crucial for brain development and is therefore especially important during pregnancy when the brain is developing most rapidly. While randomised controlled trials of pregnant women in regions of severe iodine deficiency have shown that prenatal iodine deficiency causes impaired cognition, less is known of the effects in regions of mild deficiency. This is relevant to the UK as the World Health Organisation now classifies the UK as mildly iodine deficient, based on a national study of 14-15 year old schoolgirls in 2011. We have previously published a study using samples and data from the UK-based Avon Longitudinal Study of Parents and Children (ALSPAC) that found an association between low iodine status in early pregnancy (urinary iodine-to-creatinine ratio <150 μg/g) and lower verbal IQ and reading scores in the offspring. Though the women in ALSPAC were recruited in the early 1990s, the results of the study are still relevant as their iodine status was similar to that reported in recent studies of UK pregnant women. This review discusses the evidence that mild-to-moderate iodine deficiency during pregnancy has deleterious effects on child neurodevelopment and relates that evidence to the data on iodine status in the UK. It has highlighted a need for nationwide data on iodine status of pregnant women and that a randomised controlled trial of iodine supplementation in pregnant women in a region of mild-to-moderate iodine deficiency with child outcomes as the primary endpoint is required.

    Exciting Week Ahead for Winners of Unique Astronomy Contest Following the very successful events of 1993 and 1994 [1], ESO again opens its doors for an `educational adventure' next week. It takes place within the framework of the `Third European Week for Scientific and Technological Culture', initiated and supported by the European Commission. On Tuesday, November 14, 1995, about forty 16-18 year old students and their teachers will converge towards Munich from all corners of Europe. They are the happy winners of a Europe-wide astronomy contest (`Europe Towards the Stars') that took place during the summer and early autumn. Their prize is a free, week-long stay at the Headquarters of the European Southern Observatory. During this time they will work with professional astronomers and get a hands-on experience within modern astronomy and astrophysics at one of the world's foremost international centres. In particular, the participants will be exposed to the scientific method by carrying through a research programme of their own, all the way from conception to interpretation of the data. The culmination of the stay will be the opportunity to perform remote observations via a satellite link with two major telescopes at the ESO La Silla observatory in Chile, including the very advanced 3.5-metre New Technology Telescope (NTT). The European Contest This year's EU/ESO programme was devised as a contest between joint teams of secondary school students and their teachers. The teams had to choose between four different subjects requiring either practical or theoretical work, and all with strong scientific and technological components. One subject was to devise an observational programme with an existing telescope and instrument and to discuss the resulting data in order to arrive at a scientific conclusion. This was the preferred subject by many teams. For instance, the winning German team observed the moons of Jupiter and the Danish team studied a star cluster in order to

    Migration is one of the most energy-consuming activities in the lives of birds. The timing must be such that flying would not be overly strenuous and that there would be favourable conditions for feeding and nesting available at arrival. The wide year-to-year variation in the arrival dates of migratory birds suggests that birds are able to both accelerate and delay their migration according to the weather conditions in the destination area. Often, the arrival date cannot be explained by the average daily temperature or any other single meteorological parameter. Relatively simple tools for exploring the links between climate and wildlife are weather types that combine most of the meteorological variables. The aim of the present work is to study the connections between the arrival of migratory birds in Estonia and the weather types. We examine the weather types that most frequently occurred on those days when birds arrived in Tartu (located in the Eastern part of Estonian mainland) and in Kuressaare (West-Estonian archipelago). For this purpose, the arrival dates of 42 species of migratory birds were analysed and compared to the weather types of 73 classifications generated by COST 733 action (COST 733 catalogue 1.2). Since the weather type classifications were generated using ERA40 air pressure datasets, the period available for analysis is 1958-2002. We selected weather types that occurred on the arrival dates of each migratory bird species. Also, the data on two days prior to the arrival were analysed. We assume that birds "took the decision" to fly to Estonia due to the weather conditions on those two days. Frequency of the selected weather types was analysed and compared to the long term frequency of these types during the spring season (MAM). We assume that birds "prefer" those weather types whose frequency on migration days exceeds their long-term frequency. Similarly, we studied the weather types that birds seem to avoid. The results show that despite the

    We analyse geomagnetic recordings at four subauroral and midlatitude Russian observatories in 1850-1862. The data consist of spot readings made once in hour of the north and east components of the magnetic field. We use the hourly change of the horizontal field vector as the measure of activity. We compare these values to data from modern observatories at corresponding magnetic latitudes (Nurmijärvi, Finland, magnetic latitude ~57 N; Tartu, Estonia, ~54.5 N; Dourbes, Belgium, ~46 N) by reducing their data to the 1-h format. The largest variations at the Russian observatories occurred during the Carrington storm in September 1859 and they reached about 1000 nT/h, which was the instrumental off-scale limit. When the time stamp for the spot readings happens to be optimal, the top variation in the Nurmijärvi data is about 3700 nT/h (July 1982), and at Tartu the maximum is about 1600 nT/h (November 2004). At a midlatitude site Nertchinsk in Russia (magnetic latitude ~45 N), the variation during the Carrington storm was at the off-scale limit, and exceeded the value observed at Dourbes during the Halloween storm in October 2003. At Nertchinsk, the Carrington event was at least four times larger than any other storm in 1850-1862. Despite the limitations of the old recordings and in using only hourly spot readings, the Carrington storm was definitely a very large event at midlatitudes. At higher latitudes, it remains somewhat unclear whether it exceeds the largest modern storms, especially the one in July 1982.

  12. “I thought cancer was one of those random things. I didn’t know cancer could be caught…”: Adolescent girls’ understandings and experiences of the HPV programme in the UK

    2011-01-01

    Background The UK human papillomavirus (HPV) vaccination programme aims to provide girls aged 12–13 with protection against two of the most carcinogenic strains (types 16 and 18) of this sexually transmitted virus which together account for 70% of cases of cervical cancer. Despite evidence suggesting a general lack of knowledge about HPV and its link with cervical cancer, vaccine uptake rates were generally high in the UK for the first year of the HPV vaccination programme. In countries that implemented the HPV programme ahead of the UK, studies have found that girls’ and parents’ levels of awareness about HPV have increased since implementation of the programme but that knowledge continues to be limited. This study offers some of the first insights from the UK into adolescent girls’ understandings of HPV, its link with cervical cancer, and experiences of vaccination, since the programme was introduced in September 2008. Method Eighteen focus groups were conducted between December 2009 and May 2010 with schoolgirls aged between 12 and 18 living in various parts of the UK. Results Eighty seven girls participated in these discussions. Typically, girls knew very little about HPV or how they could best protect themselves from HPV infection. Although many of the girls linked HPV to cancer, only half specifically associated it with cervical cancer. Most girls had no idea how long the vaccine would offer them protection. They assumed that HPV vaccination must be important for their health because it was recommended by people they trusted, namely parents and immunisation experts. Just over half of the girls were aware that in the future they would need to attend for cervical screening. Key concerns which girls expressed about HPV vaccination reflected their anxieties about needles, anticipated pain on injection, privacy during vaccination and fears about needle cleanliness. Conclusion Our data point to a need to continue to address gaps in knowledge about HPV and

    The rate at which girls progress through the stages of puberty in relation to body fat mass and body fat distribution and its relation to their hormonal profiles was studied. Sixty-eight schoolgirls participated in a longitudinal study during 3 yr. The girls were divided into subgroups with increasing skinfold thicknesses and waist-hip ratio. They were also grouped depending on Tanner's breast development classification (M2 and M3). The age at M2 was only marginally correlated with the menarcheal age, but the age at M2 and the time interval from that age to menarche was negatively correlated. Age at the onset of puberty was not related to body fat mass or distribution. The rate of pubertal development after pubertal stage M3 was negatively related to the body fat mass. Age at M2 was only correlated with estrone (E1), while the rate of pubertal development was associated with higher FSH, E1, estradiol (E2), the fraction of E2 that was not bound to sex-hormone-binding globulin (non-sex-hormone-binding globulin bound E2) and androstenedione plasma levels at the onset of puberty. Body fat distribution, rather than body fat mass was related to the total and the non-sex-hormone-binding globulin bound plasma levels of E2 and testosterone at the onset of puberty. Changes in body fat distribution in early female puberty were chiefly related to the waist circumferences. We found no evidence that body fat mass or body fat distribution triggers the onset of puberty. Body fat distribution was related to early pubertal endocrine activity. Body fat mass was negatively related to the rate of pubertal development toward menarche, but no clear indications for an endocrine-related process is found. We conclude that onset of puberty and menarche are not parallel pubertal events, and that early pubertal plasma E1, E2 and androstenedione levels are predictors for the rate of pubertal development toward menarche. We propose that the control of the onset of puberty and maturation of the

    We evaluated the associations of teenage insulin and adolescent diet with 10-year weight gain in an analysis sample of black and white girls matched for pubertal stage, body mass index (BMI) (or fat mass), and insulin at ages 9 to 10 years. We hypothesized that preteen insulin and insulin resistance would interact with dietary factors to positively predict increases in BMI. Furthermore, we hypothesized that increased insulin and insulin resistance, interacting with higher caloric intake during adolescence, would lead to greater increments in BMI in black girls than in white girls. Prospective 10-year follow-up was performed on 215 pairs of black and white schoolgirls matched at baseline by BMI (or fat mass), insulin, and pubertal stage, with repeated measures of body habitus, insulin, and dietary intake. When matched for BMI, black girls had higher fat-free mass and white girls had higher fat mass at ages 9 to 10 years. Black-white differences in caloric intake were not significant at ages 9 to 10 years, but black girls consumed more calories at age 19 years. Black girls consumed a greater percentage of calories from fat throughout. At age 19 years, black girls had higher BMI, fat mass index, and insulin. When matched at ages 9 to 10 years for fat mass, black girls were heavier, had higher BMI, and had greater fat-free mass. By ages 18 to 19 years, black girls continued to have higher BMI, but had accrued higher fat mass and a higher percentage of body fat. By stepwise multiple regression, 10-year increases in BMI were predicted by ages 9 to 10 years BMI, 10-year change in insulin, and a 3-way interaction between ages 9 to 10 years insulin, adolescent caloric intake, and race (higher in black girls) (all Ps < .0001). Insulin at ages 9 to 10 years interacts with caloric intake to increase BMI by age 19 years.

    High emotional stress in medical students has been observed in many studies. Our aim in this article was to assess the prevalence of symptoms of anxiety and depression among Estonian medical students and to find relationships between sleep complaints and emotional symptoms. The study group consisted of 413 medical students, ages 19-33 years, at the University of Tartu. Each was asked to complete two questionnaires: the Emotional State Questionnaire (EST-Q), containing 28 questions, and the Questionnaire on Sleep and Daytime Habits, with 25 questions. The anxiety and depression subscales from the EST-Q were applied. From the study group, 21.9% students had symptoms of anxiety, and 30.6% had symptoms of depression. The frequency of anxiety and depressive symptoms was higher in females. In regression and multiple regression analysis, we determined which sleep problems were related to emotional symptoms. The associations were different for men and women. In women, anxiety remained significantly related to waking up because of nightmares and feeling tired in the morning; depressive symptoms were related to difficulties in getting to sleep at night, waking up because of nightmares and nocturnal eating habits, daytime sleepiness, and sleepiness during school lessons. In men, significant relations were clear only for depression: difficulties in falling asleep at night before an exam and subjective sleep quality. The study demonstrated that a high percentage of medical students had emotional symptoms. We found that some sleep problems indicated underlying symptoms of anxiety and depression.

    The Estonian population-based biobank, with 52,000 participants' genetic and health data, is the largest epidemiological cohort in the Baltic region. Participants were recruited through a network of medical professionals throughout Estonia (population 1.34 million). Unique legislation as well as a broad consent form give the Estonian Genome Center, a research institute of the University of Tartu, permission to re-contact participants and to retrieve participants' data from national registries and databases. In addition to two re-contacting projects to update the health data of participants, extensive clinical characterizations have been retrieved from national registries and hospital databases regularly since 2010. Acquiring data from electronic health records and registries has provided a means to update and enhance the database of the Genome Center in a timely manner and at low cost. The resulting database allows a wide spectrum of genomic and epidemiological research to be conducted with the aim of benefitting public health. Future plans include linking the genome center database with the national health information system through X-road and exchanging data in real time, as well as using the genetic data and the technical infrastructure available for piloting personalized medicine in Estonia.

    Synthetic biology promises to create high-impact solutions to challenges in the areas of biotechnology, human/animal health, the environment, energy, materials and food security. Equally, synthetic biologists create tools and strategies that have the potential to help us answer important fundamental questions in biology. Warwick Integrative Synthetic Biology (WISB) pursues both of these mutually complementary ‘build to apply’ and ‘build to understand’ approaches. This is reflected in our research structure, in which a core theme on predictive biosystems engineering develops underpinning understanding as well as next-generation experimental/theoretical tools, and these are then incorporated into three applied themes in which we engineer biosynthetic pathways, microbial communities and microbial effector systems in plants. WISB takes a comprehensive approach to training, education and outreach. For example, WISB is a partner in the EPSRC/BBSRC-funded U.K. Doctoral Training Centre in synthetic biology, we have developed a new undergraduate module in the subject, and we have established five WISB Research Career Development Fellowships to support young group leaders. Research in Ethical, Legal and Societal Aspects (ELSA) of synthetic biology is embedded in our centre activities. WISB has been highly proactive in building an international research and training network that includes partners in Barcelona, Boston, Copenhagen, Madrid, Marburg, São Paulo, Tartu and Valencia.

    Today, the three Baltic countries Estonia, Latvia and Lithuania, have well-known medical faculties with international standing. Their individual histories are briefly outlined. However, relations of the German academic world were closest with the university of Dorpat (today: Tartu). It was re-opened in 1802 by tsar Alexander I in order to keep young Baltic people from studying abroad. The medical faculty was its biggest faculty. The university was Russian, but the official language was German. So many a German professor came to Dorpat and many professors from Dorpat were offered a chair at a German university. The scientific imports connected Dorpat with other centres of West-European science, they brought knowledge and ideas and an exchange of information. The standard was high, and among the teaching staff was a handsome number of medical celebrities, e.g. the anatomist August Rauber and the surgeon Ernst von Bergmann. In Dorpat, Rudolf Buchheim brought a new science, experimental pharmacology, into being, which his pupil and successor, Oswald Schmiedeberg, fully established and propagated all over the world.

    Genome-wide association studies (GWAS) have identified hundreds of cardiometabolic disease (CMD) risk loci. However, they contribute little to genetic variance, and most downstream gene-regulatory mechanisms are unknown. We genotyped and RNA-sequenced vascular and metabolic tissues from 600 coronary artery disease patients in the Stockholm-Tartu Atherosclerosis Reverse Networks Engineering Task study (STARNET). Gene expression traits associated with CMD risk single-nucleotide polymorphism (SNPs) identified by GWAS were more extensively found in STARNET than in tissue- and disease-unspecific gene-tissue expression studies, indicating sharing of downstream cis-/trans-gene regulation across tissues and CMDs. In contrast, the regulatory effects of other GWAS risk SNPs were tissue-specific; abdominal fat emerged as an important gene-regulatory site for blood lipids, such as for the low-density lipoprotein cholesterol and coronary artery disease risk gene PCSK9 STARNET provides insights into gene-regulatory mechanisms for CMD risk loci, facilitating their translation into opportunities for diagnosis, therapy, and prevention.

Data were also taken from a random sample telephone survey of 341 young adults (aged 18-35 years) in Texas, USA. Ten distinct groups were studied. Seven questions were common to all the surveys, using identical statements about the participants' agreement with attitudes relating to war, diplomacy, killing, and the punishment of children. FINDINGS: The US students were more likely than those in Europe to agree with the following statements: "War is necessary" (20% vs 9%), "A person has the right to kill to defend property" (54% vs 17%), and "Physical punishment is necessary for children" (27% vs 10%). Justification of war and killing was less common among females than males in all groups; other differences within the US groups and the European groups were smaller than the differences between the US and European groups. CONCLUSION: The results confirm the gap between the US and European groups in moral disengagement attitudes and tendencies that could lead to deadly violence. PMID:11417032

    Genome-wide association studies (GWAS) have identified hundreds of cardiometabolic disease (CMD) risk loci. However, they contribute little to genetic variance, and most downstream gene-regulatory mechanisms are unknown. We genotyped and RNA-sequenced vascular and metabolic tissues from 600 coronary artery disease patients in the Stockholm-Tartu Atherosclerosis Reverse Networks Engineering Task study (STARNET). Gene expression traits associated with CMD risk single-nucleotide polymorphism (SNPs) identified by GWAS were more extensively found in STARNET than in tissue- and disease-unspecific gene-tissue expression studies, indicating sharing of downstream cis-/trans-gene regulation across tissues and CMDs. In contrast, the regulatory effects of other GWAS risk SNPs were tissue-specific; abdominal fat emerged as an important gene-regulatory site for blood lipids, such as for the low-density lipoprotein cholesterol and coronary artery disease risk gene PCSK9 STARNET provides insights into gene-regulatory mechanisms for CMD risk loci, facilitating their translation into opportunities for diagnosis, therapy, and prevention.

    Development of photogrammetry has reached a new level due to the use of unmanned aerial vehicles (UAV). In Estonia, the main areas of use of UAVs are monitoring overhead power lines for energy companies and fields in agriculture, and estimating the use of stockpile in mining. The project was carried out by the order of the City of Tartu for future road construction. In this research, automation of UAV platform MUST Q aerial image processing and reduction of time spent on the use of ground control points (GCP) is studied. For that two projects were created with software Pix4D. First one was processed automatically without GCP. Second one did use GCP, but all the processing was done automatically. As the result of the project, two orthomosaics with the pixel size of 5 cm were composed. Projects allowed ensuring accuracy limit of three times of the pixel size. The project that turned out to be the most accurate was the one using ground control points to do the levelling, which remained within the error limit allowed and the accuracy of the orthomosaic was 0.132 m. The project that didn't use ground control points had the accuracy of 1.417 m.

    Wavelength-dependent attenuation of ground-level ultraviolet (UV) dose by different cloud and aerosol situations at the Tartu Observatory site (58°15' N, 26°28' E, 70 m a.s.l) is under scrutiny. The spectra at wavelengths ranging below 400 nm have been recorded by the simple Avantes, Inc. array spectrometer AvaSpec-256 in 2004-2009. The spectral information was supported by the conventional broadband solar irradiance and by the necessary meteorological data. The average cloud modification factor (CMF) on overcast days from May to August has been quite low, 0.36 in UVA and 0.35 in UVB. In the UVA range, the reduction of the daily dose with increasing noon solar zenith angle (SZA) from 35-50° to 65-80° in overcast days has been about 20% more than in clear days, while in the UVB range it was 45% larger. No clear difference in the influence of SZA on CMF between low level (St, Ns) and medium level (As, Ac) overcast cloudiness has been found. The aerosol attenuation during large aerosol optical depth (AOD) episode has been comparable with that of medium level clouds with the wavelength dependency in the UVA range different from that of clouds.

    Synthetic biology promises to create high-impact solutions to challenges in the areas of biotechnology, human/animal health, the environment, energy, materials and food security. Equally, synthetic biologists create tools and strategies that have the potential to help us answer important fundamental questions in biology. Warwick Integrative Synthetic Biology (WISB) pursues both of these mutually complementary 'build to apply' and 'build to understand' approaches. This is reflected in our research structure, in which a core theme on predictive biosystems engineering develops underpinning understanding as well as next-generation experimental/theoretical tools, and these are then incorporated into three applied themes in which we engineer biosynthetic pathways, microbial communities and microbial effector systems in plants. WISB takes a comprehensive approach to training, education and outreach. For example, WISB is a partner in the EPSRC/BBSRC-funded U.K. Doctoral Training Centre in synthetic biology, we have developed a new undergraduate module in the subject, and we have established five WISB Research Career Development Fellowships to support young group leaders. Research in Ethical, Legal and Societal Aspects (ELSA) of synthetic biology is embedded in our centre activities. WISB has been highly proactive in building an international research and training network that includes partners in Barcelona, Boston, Copenhagen, Madrid, Marburg, São Paulo, Tartu and Valencia.

    Variations of the emission lines in the spectrum of the yellow symbiotic star AG Draconis (AG Dra) have been studied for over 14 yr (1997-2011), using more than 500 spectra obtained with the 1.5-m telescope at Tartu Observatory, Estonia. The time interval covered includes the major (cool) outburst of AG Dra that started in 2006. The main findings can be summarized as follows. (i) The cool and hot outbursts of AG Dra can be distinguished from the variations of optical emission lines. (ii) The Raman scattered emission line of O VI at λ6825 almost disappeared during the cool outburst. (iii) The lower excitation emission lines did not change significantly during the cool outburst, but they do vary in hot outbursts and also follow orbital motion. (iv) The similarity of variations in AG Dra to those in the prototypical symbiotic star Z Andromedae allows us to suggest that a combination nova model proposed for the latter object might also be responsible for the outburst behaviour of AG Dra.

  9. History of experimental psychology from an Estonian perspective.

    A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

    Continuous measurements of intermediate air ion size distributions were carried out in the small town Tartu, Estonia, from 1 April 2010 through 7 November 2011. The intermediate ions are charged aerosol particles of diameter 1.5-7.5 nm. In this paper we study what information about neutral nanoparticles of atmospheric aerosols can be drawn from the air ion measurements. Rough estimates of the growth rate and the size distribution of neutral nanoparticles were derived for the subset of measurements while the concentration of the intermediate ions was close to the median and remains in the range of 21 ± 2 cm-3. This criterion excludes the specific new particle formation events characterized with high concentration of intermediate ions and includes only most typical quiet periods between the events when the simultaneous growth, depletion and recharging of particles are described with steady-state equations. We estimated the growth rate of nanoparticles to be about 2 nm h-1 while the growth flux or apparent nucleation rate proved to be about 0.5 cm-3 s-1 at 3 nm and about 0.08 cm-3 s-1 at 7 nm. The results suggest that the process of new particle formation is not interrupted during the quiet periods between events of intensive nucleation of atmospheric aerosols.

    This publication is dedicated to the 150th birth anniversary of a famous German-writing Latvian physician, historian of medicine, and anthropologist of Jewish descent Izidor Brennsohn, and to his ties with Lithuania. I. Brennsohn's works on physicians and the development of health care in Kurland, Livland, and Estland laid the foundations for the contemporary historiography of medicine in Latvia and Estonia. To a certain extent, these works could also be viewed as a digest of the sources of Lithuanian history of medicine, especially in regard to the regions on the boarder with Latvia, as well as to various personalities. However, Brennsohn's most important link with Lithuania was his doctoral thesis "On Lithuanian anthropology" ("Zur Anthropologie der Litauer"), defended at Dorpat (Tartu) University in 1883. It was one of the first works dealing with Lithuanian ethnic anthropology as a whole. Although, material of thesis could not be used for wider generalizations, still, it is one of rare and valuable 19th century sources of Lithuanian anthropology. Brennsohn's legacy deserves greater attention from people researching medical history in Lithuania. PMID:15456980

    The course of reparative regeneration after 5/6 nephrectomy and use of low-dose radiation has been studied by means of light and electron microscopy. The experiments were performed on 30 male Wistar rats. All animal procedures were conducted after approval of the protocol by the animal Studies Ethics Committee of the University of Tartu. Renal ablation was then accomplished by right nephrectomy and selective ligation of extrarenal branches of the left renal artery such that approximately 2/3 of the left kidney was infracted. All together 30 rats were randomised after the surgery and divided into two groups matched for age and body weight at week 0 and studied during 2, 4 and 8 weeks: groups I (nephrectomized, n = 15), groups II (nephrectomized and irradiated, n = 15). Left kidney of II groups rats was irradiated (60Co) 24 h after surgery in anaesthetized (Brietal) animals with 3 Gy in a single dose. As a result of experimentally induced ischemia destruction of renal corpuscles, perishing of tubular epithelial cells and and proliferation of connective tissue is followed. Reparative regeneration is based on aseptic inflammation, duration of its phases depends on the extent of organ impairment. In nephrectomized rats parallel to reparative regeneration, necrosis and deposition of calcium is found in the cortical substance. Calcium plays important role in kidney metabolism and its increased content is characteristic to degenerative changes. The experiments reveal that use of low-dose radiation does not accelerate process of reparative regeneration in rat kidney.

    Air pollution is one of the main environmental concerns in urban areas, where anthropogenic emissions strongly affect air quality. This work presents the first spatially resolved detailed characterization of PM2.5 (particulate matter with aerodynamic equivalent diameter daero ≤ 2.5 µm) in two major Estonian cities, Tallinn and Tartu. The measurements were performed in March 2014 using a mobile platform. In both cities, the non-refractory (NR)-PM2.5 was characterized by a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) using a recently developed lens which increases the transmission of super-micron particles. Equivalent black carbon (eBC) and several trace gases including carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4) were also measured. The chemical composition of PM2.5 was found to be very similar in the two cities. Organic aerosol (OA) constituted the largest fraction, explaining on average about 52 to 60 % of the PM2.5 mass. Four sources of OA were identified using positive matrix factorization (PMF): hydrocarbon-like OA (HOA, from traffic emissions), biomass burning OA (BBOA, from biomass combustion), residential influenced OA (RIOA, probably mostly from cooking processes with possible contributions from waste and coal burning), and oxygenated OA (OOA, related to secondary aerosol formation). OOA was the major OA source during nighttime, explaining on average half of the OA mass, while during daytime mobile measurements the OA was affected by point sources and dominated by the primary fraction. A strong increase in the secondary organic and inorganic components was observed during periods with transport of air masses from northern Germany, while the primary local emissions accumulated during periods with temperature inversions. Mobile measurements offered the identification of different source regions within the urban areas and the assessment of the extent to which pollutants concentrations exceeded regional background

    Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

    Antibiotics and antibiotic resistant bacteria enter wastewater treatment plants (WWTPs), an environment where resistance genes can potentially spread and exchange between microbes. Several antibiotic resistance genes (ARGs) were quantified using qPCR in three WWTPs of decreasing capacity located in Helsinki, Tallinn, and Tartu, respectively: sulphonamide resistance genes (sul1 and sul2), tetracycline resistance genes (tetM and tetC), and resistance genes for extended spectrum beta-lactams (blaoxa-58, blashv-34, and blactx-m-32). To avoid inconsistencies among qPCR assays we normalised the ARG abundances with 16S rRNA gene abundances while assessing if the respective genes increased or decreased during treatment. ARGs were detected in most samples; sul1, sul2, and tetM were detected in all samples. Statistically significant differences (adjusted p<0.01) between the inflow and effluent were detected in only four cases. Effluent values for blaoxa-58 and tetC decreased in the two larger plants while tetM decreased in the medium-sized plant. Only blashv-34 increased in the effluent from the medium-sized plant. In all other cases the purification process caused no significant change in the relative abundance of resistance genes, while the raw abundances fell by several orders of magnitude. Standard water quality variables (biological oxygen demand, total phosphorus and nitrogen, etc.) were weakly related or unrelated to the relative abundance of resistance genes. Based on our results we conclude that there is neither considerable enrichment nor purification of antibiotic resistance genes in studied conventional WWTPs. PMID:25084517

    Background Information on the neonatal exposure to excipients is limited. Our aim was to describe the extent of excipient intake by Estonian neonates; to classify the excipients according to potential neonatal toxicity and thereby to measure the extent of exposure of neonates to potentially harmful excipients. Methods A prospective cohort study that recorded all medicines prescribed to patients aged below 28 days admitted to Tartu University Hospital from 01.02-01.08 2008 and to Tallinn Children’s Hospital from 01.02- 01.08 2009 was conducted. Excipients were identified from Summaries of Product Characteristics and classified according to toxicity following a literature review. Results 1961 prescriptions comprising 107 medicines were written for 348/490 neonates admitted. A total of 123 excipients were found in 1620 (83%) prescriptions and 93 (87%) medicines. 47 (38%) of these excipients were classified as potentially or known to be harmful to neonates. Most neonates (97%) received at least one medicine (median number 2) with potentially or known to be harmful excipient. Parabens were the most commonly used known to be harmful excipients and sodium metabisulphite the most commonly used potentially harmful excipient, received by 343 (99%) and 297 (85%) of treated neonates, respectively. Conclusions Hospitalised neonates in Estonia are commonly receiving a wide range of excipients with their medication. Quantitative information about excipients should be made available to pharmacists and neonatologists helping them to take into account excipient issues when selecting medicines and to monitor for adverse effects if administration of medicines containing excipients is unavoidable.

The Baltic-Nordic Network AGMP 'Algebra, Geometry, and Mathematical Physics' http://www.agmp.eu was created in 2005 on the initiative of two Estonian universities and two Swedish universities: Tallinn University of Technology represented by Eugen Paal (coordinator of the network), Tartu University represented by Viktor Abramov, Lund University represented by Sergei Silvestrov, and Chalmers University of Technology and the University of Gothenburg represented by Alexander Stolin. The goal was to promote international and interdisciplinary cooperation between scientists and research groups in the countries of the Baltic-Nordic region in mathematics and mathematical physics, with special emphasis on the important role played by algebra and geometry in modern physics, engineering and technologies. The main activities of the AGMP network consist of a series of regular annual international workshops, conferences and research schools. The AGMP network also constitutes an important educational forum for scientific exchange and dissimilation of research results for PhD students and Postdocs. The network has expanded since its creation, and nowadays its activities extend beyond countries in the Baltic-Nordic region to universities in other European countries and participants from elsewhere in the world. As one of the important research-dissimilation outcomes of its activities, the network has a tradition of producing high-quality research proceedings volumes after network events, publishing them with various international publishers.

    Occupational exposures make important contributions to asthma morbidity. The role of low/moderate level irritant exposures remains unclear. We aimed to determine which occupational exposures are associated with asthma in an eastern European country with low asthma prevalence. The Estonian Genome Center of University of Tartu collected data from 50 077 adults in 2002-2011. Asthma was assessed through a questionnaire regarding diagnosed diseases, current health status and medication. Exposures to 22 agents during the current and longest held jobs were estimated using an asthma-specific job-exposure matrix. Analyses included 34 015 subjects (aged 18-65 years, 67.0% females), of which 1209 (3.6%) reported asthma (608 with physician-confirmed diagnosis). After adjusting for age, sex and smoking habits, lifetime occupational exposure to known asthmagens (20.4%) was significantly associated with physician-diagnosed asthma (OR 1.28, 95% CI 1.03-1.59), especially high molecular weight agents (flour: OR 2.36, 95% CI 1.31-4.27; animals: OR 1.62, 95% CI 1.00-2.60). Exposure to low/moderate levels of irritants (17.4%) was associated with physician-diagnosed asthma (OR 1.88, 95% CI 1.48-2.37). More pronounced associations were observed in subjects reporting current treated asthma. Beyond confirming the effect of known asthmagens (which are well-known, mostly from observations in western countries), the results provide evidence for a role of low/moderate exposure to irritants. This finding, observed in a country with a low prevalence of asthma and atopy, provides new insight into the understanding of asthma heterogeneity.

    Antibiotics and antibiotic resistant bacteria enter wastewater treatment plants (WWTPs), an environment where resistance genes can potentially spread and exchange between microbes. Several antibiotic resistance genes (ARGs) were quantified using qPCR in three WWTPs of decreasing capacity located in Helsinki, Tallinn, and Tartu, respectively: sulphonamide resistance genes (sul1 and sul2), tetracycline resistance genes (tetM and tetC), and resistance genes for extended spectrum beta-lactams (blaoxa-58, blashv-34, and blactx-m-32). To avoid inconsistencies among qPCR assays we normalised the ARG abundances with 16S rRNA gene abundances while assessing if the respective genes increased or decreased during treatment. ARGs were detected in most samples; sul1, sul2, and tetM were detected in all samples. Statistically significant differences (adjusted p<0.01) between the inflow and effluent were detected in only four cases. Effluent values for blaoxa-58 and tetC decreased in the two larger plants while tetM decreased in the medium-sized plant. Only blashv-34 increased in the effluent from the medium-sized plant. In all other cases the purification process caused no significant change in the relative abundance of resistance genes, while the raw abundances fell by several orders of magnitude. Standard water quality variables (biological oxygen demand, total phosphorus and nitrogen, etc.) were weakly related or unrelated to the relative abundance of resistance genes. Based on our results we conclude that there is neither considerable enrichment nor purification of antibiotic resistance genes in studied conventional WWTPs.

    Within the European multi-centre MyoAge project, one workpackage was designed to investigate the contribution of age-related changes to muscle mass, contractile characteristics and neural control in relation to reductions in mobility in older age. The methodology has been described here. Test centres were located in Manchester, UK; Paris, France; Leiden, The Netherlands; Tartu, Estonia and Jyväskylä, Finland. In total, 182 young (18-30 years old, 52.2 % female) and 322 older adults (69-81 years old, 50 % female) have been examined. The participants were independent living, socially active and free from disease that impaired mobility levels. The older participants were selected based on physical activity levels, such that half exceeded current recommended physical activity levels and the other half had lower physical activity levels than is recommended to maintain health. Measurements consisted of blood pressure; anthropometry and body composition (dual-energy X-ray absorptiometry and magnetic resonance imaging); lung function; standing balance and cognitive function (CANTAB). Mobility was assessed using the Timed Up and Go, a 6 min walk, activity questionnaires and accelerometers to monitor habitual daily activities. Muscle strength, power, fatigue and neural activation were assessed using a combination of voluntary and electrically stimulated contractions. Fasting blood samples and skeletal muscle biopsies were collected for detailed examination of cell and molecular differences between young and older individuals. The results from this study will provide a detailed insight into "normal, healthy" ageing, linking whole-body function to the structure and function of the neuromuscular system and the molecular characteristics of skeletal muscle.

    Multiannual changes in atmospheric column transparency based on measurements of direct solar radiation allow us to assess various tendencies in climatic changes. Variability of the atmospheric integral (broadband) transparency coefficient, calculated according to the Bouguer-Lambert law and transformed to a solar elevation of 30°, is used for two Russian locations, Pavlovsk and Moscow, one Ukrainian location, Feodosiya, and three Estonian locations, Tartu, Tõravere, and Tiirikoja, covering together a 102-year period, 1906-2007. The comparison of time series revealed significant parallelism. Multiannual trends demonstrate decrease in transparency during the postwar period until 1983/1984. The trend ends with a steep decline of transparency after a series of four volcanic eruptions of Soufriere (1979), Saint Helens (1980), Alaid (1981), and El Chichón (1982). From 1984/1985 to 1990 the atmosphere remarkably restored its clarity, which almost reached again the level of the 1960s. Following the eruption of Mount Pinatubo (June 1991), there was the most significant reduction in column transparency of the postwar period. However, from the end of 1990s, the atmosphere in all considered locations is characterized with high values of transparency. The clearing of the atmosphere (from 1993) evidently indicates a decrease in the content of aerosol particles and, besides the decline of volcanic activity, may therefore be also traced to environmentally oriented changes in technology (pollution prevention), to general industrial and agricultural decline in the territory of the former USSR and Eastern Europe after deep political changes in 1991, and in part to migration of some industries out of Europe.

    We studied alcohol consumption and its consequences as a seasonal phenomenon in Estonia and analysed the social and environmental factors that may cause its seasonal rhythm. There are two important questions when researching the seasonality of human activities: (1) whether it is caused by natural or social factors, and (2) whether the impact of the factors is direct or indirect. Often the seasonality of social phenomena is caused by social factors, but the triggering mechanisms are related to environmental factors like temperature, precipitation, and radiation via the circannual calendar. The indicators of alcohol consumption in the current paper are grouped as: (1) pre-consumption phenomena, i.e. production, tax and excise, sales (beer, wine and vodka are analysed separately), and (2) post-consumption phenomena, i.e. alcohol-related crime and traffic accidents and the number of people detained in lockups and admitted to alcohol treatment clinics. In addition, seasonal variability in the amount of alcohol advertising has been studied, and a survey has been carried out among 87 students of Tartu University. The analysis shows that different phenomena related to alcohol have a clear seasonal rhythm in Estonia. The peak period of phenomena related to beer is in the summer, from June to August and the low point is during the first months of the year. Beer consumption correlates well with air temperature. The consumption of vodka increases sharply at the end of the year and in June; the production of vodka does not have a significant correlation with negative temperatures. The consumption of wine increases during summer and in December. The consequences of alcohol consumption, expressed as the rate of traffic accidents or the frequency of medical treatment, also show seasonal variability. Seasonal variability of alcohol consumption in Estonia is influenced by natural factors (temperature, humidity, etc.) and by social factors (celebrations, vacations, etc.). However

The Estonian Biobank and several other biobanks established over a decade ago are now starting to yield valuable longitudinal follow-up data for large numbers of individuals. These samples have been used in hundreds of different genome-wide association studies, resulting in the identification of reliable disease-associated variants. The focus of genomic research has started to shift from identifying genetic and nongenetic risk factors associated with common complex diseases to understanding the underlying mechanisms of the diseases and suggesting novel targets for therapy. However, translation of findings from genomic research into medical practice is still lagging, mainly due to insufficient evidence of clinical validity and utility. In this review, we examine the different elements required for the implementation of personalized medicine based on genomic information. First, biobanks and genome centres are required and have been established for the high-throughput genomic screening of large numbers of samples. Secondly, the combination of susceptibility alleles into polygenic risk scores has improved risk prediction of cardiovascular disease, breast cancer and several other diseases. Finally, national health information systems are being developed internationally, to combine data from electronic medical records from different sources, and also to gradually incorporate genomic information. We focus on the experience in Estonia, one of several countries with national goals towards more personalized health care based on genomic information, where the unique combination of elements required to accomplish this goal are already in place.

  9. Young Astronomers' Observe with ESO Telescopes

    1995-11-01

    Today, forty 16-18 year old students and their teachers are concluding a one-week, educational `working visit' to the ESO Headquarters in Garching (See ESO Press Release 14/95 of 8 November 1995). They are the winners of the Europe-wide contest `Europe Towards the Stars', organised by ESO with the support of the European Union, under the auspices of the Third European Week for Scientific and Technological Culture. From November 14-20, they have worked with professional ESO astronomers in order to get insight into the methods and principles of modern astronomy and astrophysics, as carried out at one of the world's foremost international centres. This included very successful remote observations with the ESO 3.5-m New Technology Telescope (NTT) and the 1.4-m Coude Auxiliary Telescope (CAT) via a satellite link between the ESO Headquarters and the La Silla observatory in Chile, 12,000 kilometres away. After a general introduction to modern astronomy on the first day of the visit, the participants divided into six teams, according to their interests. Some chose to observe distant galaxies, others prefered to have a closer look on binary stars, and one team decided to investigate a star which is thought to be surrounded by a proto-planetary system. Each team was supported by an experienced ESO astronomer. Then followed the observations at the remote consoles during three nights, the first at the NTT and the following at the CAT. Each team had access to the telescope during half a night. Although the work schedule - exactly as in `real' science - was quite hard, especially during the following data reduction and interpretative phase, all teams managed extremely well and in high spirits. The young astronomers' observations were favoured by excellent atmospheric conditions. At the NTT, the seeing was better than 0.5 arcsecond during several hours, an exceptional value that allows very good images to be obtained. All observations represent solid and interesting science, and

    The joint International Symposium RCBJSF-2014-FM&NT successfully has united two international events - 12th Russia/CIS/Baltic/Japan Symposium on Ferroelectricity (RCBJSF-12) and 9th International Conference Functional Materials and Nanotechnologies (FM&NT-2014). The RCBJSF symposium is a continuation of series of meetings on ferroelectricity, the first of which took place in Novosibirsk (USSR) in 1976. FM&NT conferences started in 2006 and have been organized by Institute of Solid State Physics, University of Latvia in Riga. In 2012 the International program committee decided to transform this conference into a traveling Baltic State conference and the FM&NT-2013 was organized by the Institute of Physics, University of Tartu, Estonia. In 2014 the joint international symposium RCBJSF-2014-FM&NT was organized by the Institute of Solid State Physics, University of Latvia and was part of Riga - 2014, the European Capital of Culture event. The purpose of the joint Symposium was to bring together scientists, students and high-level experts in solid state physics, materials science, engineering and related disciplines. The number of the registered participants from 26 countries was over 350. During the Symposium 128 high quality scientific talks (5 plenary, 42 invited, 81 oral) and over 215 posters were presented. All presentations were divided into 4 parallel sessions according to 4 main topics of the Symposium: Ferroelectricity, including ferroelectrics and multiferroics, pyroelectrics, piezoelectrics and actuators, integrated ferroelectrics, relaxors, phase transitions and critical phenomena. Multifunctional Materials, including theory, multiscale and multiphenomenal material modeling and simulation, advanced inorganic, organic and hybrid materials. Nanotechnologies, including progressive methods, technologies and design for production, investigation of nano- particles, composites, structures, thin films and coatings.

    Symbiotic stars are interacting binaries whose components are a red giant and a small hot star, usually a white dwarf. The intensive stellar wind from the giant is captured by the companion, giving rise to strong emission lines in the spectra and a range of phenomena, which may include the formation of an accretion disk and the ejection of collimated jets. In this thesis, four symbiotic stars, as different as possible, were chosen for a spectral investigation of the symbiotic phenomenon. Of those, Z Andromedae is a so-called classical symbiotic star with a hot companion that shows a characteristic pattern of brightenings (outbursts). AG Draconis is a bright system like Z Andromedae and shows similar activity, but has an unusually hot yellow donor star. CH Cygni and EG Andromedae have, on the contrary, relatively dim white dwarfs. The former shows irregular outbursts, the origin of which is not easy to explain, the latter is one of the quiet symbiotic stars with no outburst yet recorded. Each of those four stars was observed for at least ten years with the 1.5-m telescope at Tartu Observatory. Several outbursts of Z Andromedae and AG Draconis were witnessed, as well as substantial changes in the CH Cygni spectra. The perhaps most surprising result was the discovery of collimated jets in Z Andromedae spectra on two instances, an event never observed in this star before. In CH Cygni, evidence for the existence of an accretion disk in 1998 was discovered. EG Andromedae stayed quiet and the only changes in its spectra could be ascribed to orbital motion. We found that not all the outbursts of Z Andromedae and AG Draconis are accompanied by similar changes in the spectra: during some brightenings the stars become hotter, during some, cooler. The existence of the disk in CH Cygni in 1998 affirms that the formation of such a structure is possible in symbiotic stars. Moreover, as the ejection of jets is associated to an accretion disk, the jets in Z Andromedae can also be

    Hermann Abich was born in 1806 in Berlin and died in 1886 in Graz. He grew up in a wealthy family which had friendly relations with famous scientists like Alexander von Humboldt, Leopold von Buch or Carl Ritter. After his studies in Heidelberg and Berlin he turned to extended fieldwork at the volcanoes of Italy. In 1833 1834 he published excellent petrological/chemical results and got soon a good scientific reputation. Thus he was nominated as Professor for Geology and Mineralogy of the prestigious Russian University in Dorpat (now Tartu, Esthonia) in 1842. In 1844 he was sent to Armenia by the Russian authorities. For the next three decades his fieldwork with about 190 publications was concentrated on the Great and Lesser Caucasus. This was a period of Russian expansion to the South with long-lasting regional fights. But he enjoyed the support of powerful governors. He was an indefatigable and enthusiastic explorer and a precise observer and designer. His interests covered many fields: morphology, glaciology, structural geology, volcanology with Thermal Springs, mineral resources from hydrocarbons, coal, salt to ores, stratigraphy and paleontology as a base for geological maps. But he also gave advice for practical problems, and he was active in meteorology, botany and archaeology. Alltogether he became “the Father of Caucasus Geology”. The following sketch stresses only on three aspects of his activities. He was one of the first pioneers in hydrocarbon exploration, especially around the anticlines with the mud volcanoes near Baku. In many respects, however, his fundamental ideas were erronous. He explained the structure of the Great Caucasus by the traditional theories of Leopold von Buch and Elie de Beaumont. The Caucasus anticline “was elevated by forces acting from beneath”. Following them he tried to discover regularities in the strike of mountain chains. Similarily he treated volcanism like Alexander von Humboldt and Leopold von Buch with their two

    Vana, Marko; Tamm, Eduard

    Area of representativeness (AR) of atmospheric aerosol measurements and horizontal dimensions of a cloud of particles are estimated by time series of aerosol particle size number spectrum measured simultaneously at two locations. The distances between sampling points are varied, 7, 30, 50, 100 or 375 km. The spectrum in form of 12 fraction concentrations is measured every 10 or 15 min during five 2-4 week measurement campaigns in Estonia. During one measurement campaign one measurement point was in Estonia (Tahkuse) and the other in Finland (Hyytiälä). Two electrical aerosol spectrometers (EAS) designed at University of Tartu, having diameter range 10 nm-10 μm, were used. At Hyytiälä, the particle size spectrum ( d=3-500 nm ) was measured by two Hauke type differential mobility analysers (DMA). The transport of the submicron fraction ( d=60 nm -1 μm ) of atmospheric aerosol is investigated during the time intervals when an air mass moves from the one measurement point towards the other or crosswise to this direction. Sample cross-correlation functions (SCCF) are calculated between prewhitened time series. The time lag corresponding to the mode of these functions are found to be 3-5 h for upwind-downwind case and zero for crosswind case. This time lag should indicate the mean time of pollution transport for upwind-downwind case. A certain minimal distance between sampling points should exist, when statistically significant correlation between the time series cannot be found. Considering this circumstance, the half-width of the AR is estimated. It is found to be more than 100 km but less than 375 km when the sampling points are located on the same line with the wind direction; and more than 50 km but less than 100 km when the sampling points are located on a straight line crosswise to the wind direction. The pollutant concentrations in the limits of AR are estimated by regression analysis. To support these results, the dispersion calculations by HYSPLIT (Hybrid

    New policy concerning expanded European and non-European A&A memberships: It is now thirty-five years since the scientific journal Astronomy & Astrophysics (A&A) was founded by the merging of six national journals from four European nations, namely France, Germany, the Netherlands and Sweden; Belgium and the other Nordic countries, Denmark, Finland and Norway, also participated. They were subsequently joined by five other western European nations, namely Austria, Greece, Italy, Spain and Switzerland (Norway later withdrew). A&A has no international legal status as such but is represented by the European Southern Observatory (ESO), which also manages its financial transactions. In the early nineteen-nineties, A&A with great foresight took an important step - which the European Union would follow more than a decade later - by incorporating eastern European countries into its sponsoring membership: the Czech Republic, Hungary, Poland and the Slovak Republic; Estonia became a full member in 1998. A&A was now truly ``A European Journal", as then stated on the front cover. In the meantime, A&A grew in importance as a vehicle for world-wide dissemination of astronomical research and an ever-increasing number of high-quality papers began streaming into the A&A Editorial offices from non-European countries, as well as from other European non-member countries. It became obvious to us that A&A no longer was merely a European Journal and in 2001 we removed the ``A European Journal'' from the front cover. Eventually, some of these non-European countries began approaching us with queries about potential membership in A&A and in 2002 we admitted the first such country, Argentina, with an observer status. Meanwhile, the Board intensified its study of the financial and administrative consequences of a wider expansion including the admission of member countries beyond Europe - a special subcommittee was appointed.

    The paper lays out the short scientific history and characteristics of the new probiotic Lactobacillus fermentum strain ME-3 DSM-14241, elaborated according to the regulations of WHO/FAO (2002). L. fermentum ME-3 is a unique strain of Lactobacillus species, having at the same time the antimicrobial and physiologically effective antioxidative properties and expressing health-promoting characteristics if consumed. Tartu University has patented this strain in Estonia (priority June 2001, patent in 2006), Russia (patent in 2006) and the USA (patent in 2007). The paper describes the process of the identification and molecular typing of this probiotic strain of human origin, its deposition in an international culture collection, and its safety assessment by laboratory tests and testing on experimental animals and volunteers. It has been established that L. fermentum strain ME-3 has double functional properties: antimicrobial activity against intestinal pathogens and high total antioxidative activity (TAA) and total antioxidative status (TAS) of intact cells and lysates, and it is characterized by a complete glutathione system: synthesis, uptake and redox turnover. The functional efficacy of the antimicrobial and antioxidative probiotic has been proven by the eradication of salmonellas and the reduction of liver and spleen granulomas in Salmonella Typhimurium-infected mice treated with the combination of ofloxacin and L. fermentum strain ME-3. Using capsules or foodstuffs enriched with L. fermentum ME-3, different clinical study designs (including double-blind, placebo-controlled, crossover studies) and different subjects (healthy volunteers, allergic patients and those recovering from a stroke), it has been shown that this probiotic increased the antioxidative activity of sera and improved the composition of the low-density lipid particles (LDL) and post-prandial lipids as well as oxidative stress status, thus demonstrating a remarkable anti-atherogenic effect.

    The study aims were the chemical characterization of the soil organic matter and to find out whether the effect of the different plant species on the soil organic matter is possible to detect using the FTIR spectrometer. A special experiment was established in 1964 and initiated in Tartu, Estonia to study pedogenesis and its continuous development under grass-herbaceous vegetation on reddish-brown calcareous sandy loam moraine (BC-horizon) which was practically free from soil organic carbon (SOC) (1.28 g kg-1). There were three treatments: (i) without plants; (ii) grasses and white clover (Phleum pratense, Festuca pratensis, Poa Pratensis, Trifolium repens); (iii) hybrid lucerne (Medicago varia). In 2014 the soil samples were collected from the 0-20 cm depth, air dried and sieved to 1 mm. The content of the SOC was determined by Tjurin method. Also the FTIR spectra were obtained on a Nicolet 550 Magna-IR spectrometer equipped with OMNIC software. The SOC concentration in soil samples from the upper 20 cm of the profile responded significantly to 50 years of different treatments. Without plants the SOC content increased up to 3.5 g kg-1; in grasses-clover treatment up to 9.1 g kg-1 and in hybrid lucerne treatment up to 10.7 g kg-1. The FTIR transformation spectra of the soil from different treatment showed the same peak pattern. A sharp and intense band was recorded in the 1030 cm-1 region (polysaccharides and Si-O vibrations of clay minerals). Intense bands were recorded at 1630 cm-1 (C=O vibrations of carboxylates and aromatic vibrations) and 1450 cm-1 (CH and NH bending motions and carbon oxygen bond vibrations). The peaks at the 1630 and 1450 cm-1 were lower in soil without plants and higher in hybrid lucerne treatment. This indicates that the increase of SOC content is related to the increase of proportion of lignin, other aromatics and aliphatic carboxylates which have phenolic and aliphatic structure.

  17. Intermediate ions in the atmosphere

    Intermediate air ions are charged nanometer-sized aerosol particles with an electric mobility of about 0.03-0.5 cm2 V- 1 s- 1 and a diameter of about 1.5-7.5 nm. Intensive studies of new particle formation provided good knowledge about intermediate ions during burst events of atmospheric aerosol nucleation. Information about intermediate ions during quiet periods between the bursts remained poor. The new mobility analyzer SIGMA can detect air ions at concentrations of mobility fractions of about 1 cm- 3 and enables studying intermediate ions during quiet periods. It became evident that intermediate ions always exist in atmospheric air and should be considered an indicator and a mediator of aerosol nucleation. The annual average concentration of intermediate ions of one polarity in Tartu, Estonia, was about 40 cm- 3 while 5% of the measurements showed a concentration of less than 10 cm- 3. The fraction concentrations in logarithmic 1/8-decade mobility bins between 0.1 and 0.4 cm2 V- 1 s- 1 often dropped below 1 cm- 3. The bursts of intermediate ions at stations separated by around 100 km appeared to be correlated. The lifespan of intermediate ions in the atmosphere is a few minutes, and they cannot be carried by wind over long distances. Thus the observed long-range correlation of intermediate ions is explained by simultaneous changes in air composition in widely spaced stations. A certain amount of intermediate ion bursts, predominantly of negative polarity, are produced by the balloelectric effect at the splashing of water drops during rain. These bursts are usually excluded when speaking about new particle formation because the balloelectric particles are assumed not to grow to the size of the Aitken mode. The mobility distribution of balloelectric ions is uniform in shape in all measurements. The maximum is located at a mobility of about 0.2 cm2 V- 1 s- 1, which corresponds to the diameter of particles of about 2.5 nm.

  18. Urban soils: properties for utilitzation for green infrastructure and urban agriculture

    2015-04-01

    The human influenced soils in urban areas are of prime importance to human populations. Also, it is becoming a trend that there is large increase in reclaimed lands and new users for old industrial areas. Very often the urban soils are heavily modified by different anthropogenic factors. Therefore, it makes it essential to collect the data and knowledge of urban soils in order to understand better how such soils can be managed, rehabilitated or reconditioned to support green infrastructure or urban agriculture. Although the soil organic carbon (SOC) is the largest carbon stock in terrestrial ecosystems and the carbon sequestration is a widely accepted soil function there is still few studies mapping the carbon stocks in urban areas using digital soil mapping techniques. For urban land-use planning and decision making in a process of green infrastructure sustainable development it is in major importance. The urban soils are often lacking sufficient amount of organic matter but they are degraded (compacted, builded, contaminated by construction debris, graded) making them unsuitable as a growing medium. Therefore, the use of certain green infrastructure practices and the development of urban agriculture can be challenging in an urban environment. The issue of assessing soil quality becomes two-fold: the health of the soil as a growing medium needs to be addressed as well as the possible contamination that may be present. Knowing the development history of a parcel is key to determining what type of soil testing should be done, if any, prior to redevelopment or reuse. For current, pilot scale study the soil sampling was carried out in Tartu, Estonia. The different microenvironments were determined inside of urban areas. Soils were collected from such a microenvironments as urban garden areas, parks, other green infrastructure elements. The soils were analyzed for main agrochemical and physical properties at the Estonian University of Life Sciences, laboratory of the

    This study is aimed to analyse relationships between the environmental factors and the spatial distribution of the main functional genes nirS, nirK, and nosZ regulating the denitrification process. Variations in hydrological regime, soil temperature and peat quality have been taken into the consideration at both local and global scale. Measurements of greenhouse gas (GHG) emissions using static chambers, groundwater analysis, gas and peat sampling for further laboratory analysis has been conducted in various peatlands in Iceland (two study areas, 2011), Transylvania/Romania (2012), Santa Catarina/Brazil (2012), Quebec/Canada (2012), Bashkortostan/Russian Federation (two study areas, 2012), Sichuan/China (2012), Estonia (two study areas, 2012), Florida/USA (2013, Sologne/France (2013), Jugra in West Siberia/Russia (2013), Uganda (2013), French Guyana (two study areas, 2013), Tasmania (two study areas, 2014) and New Zealand (two study areas, 2014). In each study area at least 2 transects along the groundwater depth gradient, one preferably in undisturbed, another one in drained area, and at least 3 rows of sampling sites (3-5 replicate chambers and 1 piezometer and soil sampling plot in each) in both has been established for studies. In each transect GHG emission was measured during 2-3 days in at least 5 sessions. In addition, organic sediments from the artificial riverine wetlands in Ohio/USA in 2009 and relevant gas emission studies have been used in the analyses. In the laboratories of Estonian University of Life Sciences and the University of Tartu, the peat chemical quality (pH, N, P, C, NH4, NO3) and N2O, CO2, and CH4 concentration in gas samples (50mL glass bottles and exetainers) were analysed. The peat samples for further pyrosequencing and qPCR analyses are stored in fridge by -22oC. This presentation will consider the variation of GHG emissions and hydrological conditions in the study sites. In addition, several selected biophysical factors will be taken

    Soil organic matter (SOM) is considered to be as the most important factor in soil forming, development and continuous functioning. Sequestrated into SOM organic carbon concentrations, pools and residence time in soil, as well acting intensity of interconnected with SOM edaphon are soil type specific or characteristic to certain soil types. In depending on soil moisture regime, calcareousness and clay content for each soil type certain soil organic carbon (SOC) retaining capacity and its vertical distribution pattern are characteristic. However, land use change (crop rotation, continuous cropping, no-tillage, melioration, rewetting) has greatest influence mainly on fabric of epipedon and biological functions of soil cover. Stagnic Albeluvisols are largely distributed at Tartu County. They form here more than half from arable soils. The establishment of long-term field trial and forest research area in these regions for biochemical analysis of Stagnic Albeluvisols' organic matter is in all respects justified. In 1989, an international long-term experiment on the organic nitrogen or IOSDV (Internationale Organische Stickstoffdauerdiingungsversuche) with three-field crop rotation (potato - spring wheat - spring barley) was started at Eerika near Tartu (58° 22.5' N; 26° 39.8' E) on Stagnic Albeluvisol. The main aims of this study were to determine the long-term effects of cropping systems on physico-chemical properties of soils and their productivity. The design of this field experiment is similar to other European network of IOSDV experiments. Before the establishment of this experiment in 1989 it was in set-aside state (5-6 years) as field-grass fallow. It was used as arable land in condition of state farm during 1957-83. Average agrochemical characteristics of the plough horizon of soil in the year of establishment were the following: humus content 17.1 g kg-1, total nitrogen content 0.9 g kg-1, C:N ratio 11 and pHKCl 6.3. DL soluble phosphorus content was 44 mg

    1. New A&A memberships and scientific editorial structure for the Letters section At its meeting in Tartu, Estonia on 8 May 2004, the A&A Board of Directors decided to grant observer status on the Board to Brazil, Chile, and Portugal (Sandqvist 2004, A&A, 426, E15). Then on 6-7 May 2005, at its meeting in La Laguna, Spain, the Board of Directors admitted these three countries to full membership in A&A, starting 1 January 2006. The Letters Editor, Dr. P. Schneider, will complete his terms of service on 31 January 2006. A&A is indebted to him for his thoughtful and competent editing over the past several years. As a consequence of his departure, the Board has decided to restructure the manner in which the Letters will be handled as of 1 January 2006. The Associate Editor-in-Chief, Dr. M. Walmsley, will also become Editor-in-Chief for the Letters, and he will forward the Letters to the appropriate topical Associate Editor to organize the reviewing process. Likewise, the Editor-in-Chief, Dr. C. Bertout, will become the Associate Letters-Editor-in-Chief. This change will permit a more specialized treatment of Letters in the future and also allow Letters to benefit from language editing. Hence, after 1 January 2006, manuscripts for Letters should be submitted via the A&A Manuscript Management System (MMS) that is already in place for Main Journal submissions. Letters submitted before that will be handled by the current Letters Editor even after 1 January 2006. 2. New Associate Editor positions Considering both the increased workload on the Associate Editors due to the above change and the continuing specialization of sub-fields in astronomy, the Board decided to open two new positions for Associate Editors, one specialized in Cosmology with a particular interest in theoretical aspects and the other in Observational Stellar Physics. Applications are invited for these two new positions. The Associate Editors are expected to have a broad knowledge of astronomy and

    other part of Estonia. * Soil and Waterbodies as Components of Ecosystems Both these projects - soil and waterbodies - involve meeting with scientists, practical investigation into these ecosystems and laboratory work at school, students' written studies and reports presented at a conference. The above mentioned projects were conducted under the supervision of young academics working at Estonian University of Life Sciences and the Museum of Soils in Tartu, as well as and the Limnology Centre at lake Võrtsjärv. Samples of soils were collected from Viljandi and some fields in the county to determine the texture , pH level, carbonates, content of organic matter, N-P-K level; conductivity and chemical absorption were studied also. In conclusion the soils in the town were in good condition, fertile, mostly sandy loam and lightly acid. As an outcome suggestions were given for garden projects. In the Limnology Centre at lake Võrtsjärv water samples were taken and conclusions drawn on the condition and hydrochemical characteristics and of the ecosystem of Estonia's second largest lake.

    STUDY QUESTION Can spontaneous premature ovarian failure (POF) patients derived from population-based biobanks reveal the association between copy number variations (CNVs) and POF? SUMMARY ANSWER CNVs can hamper the functional capacity of ovaries by disrupting key genes and pathways essential for proper ovarian function. WHAT IS KNOWN ALREADY POF is defined as the cessation of ovarian function before the age of 40 years. POF is a major reason for female infertility, although its cause remains largely unknown. STUDY DESIGN, SIZE, DURATION The current retrospective CNV study included 301 spontaneous POF patients and 3188 control individuals registered between 2003 and 2014 at Estonian Genome Center at the University of Tartu (EGCUT) biobank. PARTICIPANTS/MATERIALS, SETTING, METHODS DNA samples from 301 spontaneous POF patients were genotyped by Illumina HumanCoreExome (258 samples) and HumanOmniExpress (43 samples) BeadChip arrays. Genotype and phenotype information was drawn from the EGCUT for the 3188 control population samples, previously genotyped with HumanCNV370 and HumanOmniExpress BeadChip arrays. All identified CNVs were subjected to functional enrichment studies for highlighting the POF pathogenesis. Real-time quantitative PCR was used to validate a subset of CNVs. Whole-exome sequencing was performed on six patients carrying hemizygous deletions that encompass genes essential for meiosis or folliculogenesis. MAIN RESULTS AND THE ROLE OF CHANCE Eleven novel microdeletions and microduplications that encompass genes relevant to POF were identified. For example, FMN2 (1q43) and SGOL2 (2q33.1) are essential for meiotic progression, while TBP (6q27), SCARB1 (12q24.31), BNC1 (15q25) and ARFGAP3 (22q13.2) are involved in follicular growth and oocyte maturation. The importance of recently discovered hemizygous microdeletions of meiotic genes SYCE1 (10q26.3) and CPEB1 (15q25.2) in POF patients was also corroborated. LIMITATIONS, REASONS FOR CAUTION This is a

    Exhausted milled peat areas have been left behind as a result of decades-lasting intensive peat production in Estonia and Europe. According to different data there in Estonia is 10 000 - 15 000 ha of exhausted milled peat areas that should be vegetated. Restoration using Sphagnum species is most advantageous, as it creates ecological conditions closest to the natural succession towards a natural bog area. It is also thought that the large scale translocation of vegetation from intact bogs, as used in some Canadian restoration trials, is not applicable in most of European sites due to limited availability of suitable donor areas. Another possibility to reduce the CO2 emission in these areas is their use for cultivation of species that requires minimum agrotechnical measures exploitation. It is found by experiments that it is possible to establish on Vaccinium species for revegetation of exhausted milled peat areas. Several physiological activity of the plant is regulated by the number of phytohormones. These substances in low quantities move within the plant from a site of production to a site of action. Phytohormone, indole-3-acetic acid (IAA) is formed in soils from tryptophane by enzymatic conversion. This compound seems to play an important function in nature as result to its influence in regulation of plant growth and development. A principal feature of IAA is its ability to affect growth, development and health of plants. This compound activates root morphology and metabolic changes in the host plant. The physiological impact of this substance is involved in cell elongation, apical dominance, root initiation, parthenocarpy, abscission, callus formation and the respiration. The investigation areas are located in the county of Tartu (58˚ 22' N, 26˚ 43' E), in the southern part of Estonia. The soil of the experimental fields belongs according to the WRB soil classification, to the soils subgroups of Fibri-Dystric Histosols. The investigation areas were

    Little is known about human entrainment under natural conditions, partly due to the complexity of human behavior, torn between biological and social time and influenced by zeitgebers (light-dark cycles) that are progressively "polluted" (and thereby weakened) by artificial light. In addition, data about seasonal variations in sleep parameters are scarce. We, therefore, investigated seasonal variation in cross-sectional assessments of sleep/wake times of 9765 subjects from four European populations (EGCUT = Estonian Genome Centre, University of Tartu in Estonia; KORA = Cooperative Health Research in the Region of Augsburg in Germany; KORCULA = The Korcula study in Croatia; and ORCADES = The Orkney Complex Disease Study in Scotland). We identified time-of-year dependencies for the distribution of chronotype (phase of entrainment assessed as the mid-sleep time point on free days adjusted for sleep deficit of workdays) in cohorts from Estonia (EGCUT) and Germany (KORA). Our results indicate that season (defined as daylight saving time - DST and standard zonetime periods - SZT) specifications of photoperiod influence the distribution of chronotype (adjusted for age and sex). Second, in the largest investigated sample, from Estonia (EGCUT; N = 5878), we could detect that seasonal variation in weekly average sleep duration was dependent on individual chronotype. Later chronotypes in this cohort showed significant variation in their average sleep duration across the year, especially during DST (1 h advance in social time from the end of March to end of October), while earlier chronotypes did not. Later chronotypes not only slept less during the DST period but the average chronotype of the population assessed during this period was earlier than during the SZT (local time for a respective time zone) period. More in detail, hierarchical multiple regression analyses showed that, beyond season of assessment (DST or SZT), social jetlag (SJl; the discrepancy
