    The rapid increase of breast cancer in Taiwan has prompted the authors to evaluate the predictive factors of early menarche among contemporary Taiwanese girls. A total of 895 four-grade girls from eight elementary schools in Taipei City and County were identified as a closed cohort from the first semester of 1993. Data were collected from self-administered questionnaires and school records. A total of 799 girls who had not menstruated in the first year remained in the group through 1994. The effects of potential predictive factors were assessed by logistic regression. Among the 799 girls followed, 69 (8.6%) had first menstruation between the fourth and fifth grades. Height, weight, body mass index and maternal early onset of menarche were positively related to the onset of menarche within the preceding year. Energy consumption during exercise showed only moderate association after being adjusted for age and weight. Calorie intake from junk food was not associated with early menarche within the preceding year. Poor interpersonal family relationships and stressful life events also showed a moderate association with early menarche. The data obtained supported the hypothesis that height, weight, body mass index and maternal early menarche are positive predictive factors of early menarche. The effects of exercise and childhood stress are less prominent.

    Epidemiological evidence suggests that early menarche, defined as onset of menses at age 11 or earlier, has increased in prevalence in recent birth cohorts and is associated with multiple poor medical and mental health outcomes in adulthood. There is evidence that childhood adversities occurring prior to menarche contribute to early menarche. Data collected in face-to-face interviews with a nationally representative sample of women age 18 and over (N = 3288), as part of the National Comorbidity Survey-Replication, were analyzed. Associations between pre-menarchal childhood adversities and menarche at age 11 or earlier were estimated in discrete time survival models with statistical adjustment for age at interview, ethnicity, and body mass index. Adversities investigated included physical abuse, sexual abuse, neglect, biological father absence from the home, other parent loss, parent mental illness, parent substance abuse, parent criminality, inter-parental violence, serious physical illness in childhood, and family economic adversity. Mean age at menarche varied across decadal birth cohorts (χ(2)₍₄₎ = 21.41, p Childhood adversities were also more common in younger than older cohorts. Of the 11 childhood adversities, 5 were associated with menarche at age 11 or earlier, with OR of 1.3 or greater. Each of these five adversities is associated with a 26% increase in the odds of early menarche (OR = 1.26, 95% CI 1.14-1.39). The relationship between childhood sexual abuse and early menarche was sustained after adjustment for co-occurring adversities. (OR = 1.77, 95% CI 1.21-2.6). Evidence from this study is consistent with hypothesized physiological effects of early childhood family environment on endocrine development. Childhood sexual abuse is the adversity most strongly associated with early menarche. However, because of the complex way that childhood adversities cluster within families, the more generalized influence of highly dysfunctional

    Are parity and the timing of menarche associated with premature and early natural menopause? Early menarche (≤11 years) is a risk factor for both premature menopause (final menstrual period, FMP menopause (FMP 40-44 years), a risk that is amplified for nulliparous women. Women with either premature or early menopause face an increased risk of chronic conditions in later life and of early death. Findings from some studies suggest that early menarche and nulliparity are associated with early menopause, however overall the evidence is mixed. Much of the evidence for a direct relationship is hampered by a lack of comparability across studies, failure to adjust for confounding factors and inadequate statistical power. This pooled study comprises 51 450 postmenopausal women from nine observational studies in the UK, Scandinavia, Australia and Japan that contribute to the International collaboration for a Life course Approach to reproductive health and Chronic disease Events (InterLACE). Age at menarche (categorized as ≤11, 12, 13, 14 and 15 or more years) and parity (categorized as no children, one child and two or more children) were exposures of interest. Age at FMP was confirmed by at least 12 months of cessation of menses where this was not the result of an intervention (such as surgical menopause due to bilateral oophorectomy or hysterectomy) and categorized as premature menopause (FMP before age 40), early menopause (FMP 40-44 years), 45-49 years, 50-51 years, 52-53 years and 54 or more years. We used multivariate multinomial logistic regression models to estimate relative risk ratio (RRR) and 95% CI for associations between menarche, parity and age at FMP adjusting for within-study correlation. The median age at FMP was 50 years (interquartile range 48-53 years), with 2% of the women experiencing premature menopause and 7.6% early menopause. Women with early menarche (≤11 years, compared with 12-13 years) were at higher risk of premature menopause (RRR 1

    Full Text Available Several components of dairy products have been linked to earlier menarche.This study assessed whether positive associations exist between childhood milk consumption and age at menarche or the likelihood of early menarche (<12 yrs in a U.S sample. Data derive from the National Health and Nutrition Examination Survey (NHANES 1999-2004. Two samples were utilized: 2657 women age 20-49 yrs and 1008 girls age 9-12 yrs. In regression analysis, a weak negative relationship was found between frequency of milk consumption at 5-12 yrs and age at menarche (daily milk intake β = -0.32, P<0.10; "sometimes/variable milk intake" β = -0.38, P<0.06, each compared to intake rarely/never. Cox regression yielded no greater risk of early menarche among those who drank milk "sometimes/varied" or daily vs. never/rarely (HR: 1.20, P<0.42, HR: 1.25, P<0.23, respectively. Among the 9-12 yr olds, Cox regression indicated that neither total dairy kcal, calcium and protein, nor daily milk intake in the past 30 days contributed to early menarche. Girls in the middle tertile of milk intake had a marginally lower risk of early menarche than those in the highest tertile (HR: 0.6, P<0.06. Those in the lowest tertiles of dairy fat intake had a greater risk of early menarche than those in the highest (HR: 1.5, P<0.05, HR: 1.6, P<0.07, lowest and middle tertile, respectively, while those with the lowest calcium intake had a lower risk of early menarche (HR: 0.6, P<0.05 than those in the highest tertile. These relationships remained after adjusting for overweight or overweight and height percentile; both increased the risk of earlier menarche. Blacks were more likely than Whites to reach menarche early (HR: 1.7, P<0.03, but not after controlling for overweight.There is some evidence that greater milk intake is associated with an increased risk of early menarche, or a lower age at menarche.

    Full Text Available Abstract Background Evidence suggests that early menarche is positively associated with adiposity in adulthood. However, it is important to assess whether this association is due to early menarche or to the association of adiposity in late childhood with age at menarche. We evaluated the association between age at menarche and body composition in adolescence and adulthood, among subjects who have been prospectively followed in two Brazilian birth cohort studies. Methods In 1982 and 1993, the hospitals births in Pelotas were identified, and these subjects have been followed for several times. Information on age at menarche was obtained from the women (1982 cohort and their mothers (1993 cohort. At 30 and 18 years, the following body composition measures were evaluated: body mass index, waist circumference, fat-free mass index and fat mass index measured by dual-energy x-ray absorptiometry, and thickness of the abdominal visceral fat layer measured by ultrasound. The analyses were adjusted for: birth weight, maternal pregestational weight, gestational age, family income, household score index, maternal schooling, weight-for-height z-score at 4 years (1982, and body mass index at 11 years (1993. Results At 30 and 18 years, 2045 and 2092 women were evaluated, respectively. The prevalence of early menarche (≤11 years of age was 24.7 % in the 1982 and 27.6 % in the 1993 cohort. In the 1982 cohort, early menarche was positively associated with all body composition variables compared to those with late menarche (≥14 years of age even after adjusting for confounders (fat mass index: 2.33 kg/m2, 95 % Confidence interval: 1.64; 3.02. However, in the 1993 cohort, after adjusting for body mass index at 11 years, the regression coefficient for the association with fat mass index decreased from 2.2 kg/m2 (95 % Confidence interval: 1.7; 2.6 to 0.26 (95 % Confidence interval: −0.08; 0.60.

    Prior research indicates that being reared in stressful environments is associated with earlier onset of menarche in girls. In this research, we examined (a) whether these effects are driven by exposure to certain dimensions of stress (harshness or unpredictability) during the first 5 years of life and (b) whether the negative effects of stress on the timing of menarche are buffered by secure infant-mother attachment. Results revealed that (a) exposure to greater harshness (but not unpredictability) during the first 5 years of life predicted earlier menarche and (b) secure infant-mother attachment buffered girls from this effect of harsh environments. By connecting attachment research to its evolutionary foundations, these results illuminate how environmental stressors and relationships early in life jointly affect pubertal timing. © The Author(s) 2016.

  11. Early Menarche is Associated With Preference for Masculine Male Faces and Younger Preferred Age to Have a First Child

    Full Text Available One developmental factor that is associated with variation in reproductive strategy is pubertal timing. For instance, women who experience earlier menarche have their first pregnancy earlier and prefer more masculinized male voices. Early menarche may also lead to preferences for masculine faces, but no study has shown such a link. We therefore investigated the relationships between pubertal timing, reproductive plans, sexual attitudes and behaviors, and masculinity preferences in nulliparous women aged 18–30 from the United Kingdom (N = 10,793. We found that women who experienced earlier menarche reported a younger preferred age to have a first child and showed stronger masculinity preferences. This provides evidence that women experiencing early menarche not only have children earlier but notably plan to have children earlier. Additionally, our findings provide evidence that age of menarche influences partner selection, which is instrumental for the implementation of reproductive strategies.

    Full Text Available The age at which a female reaches sexual maturity is critical in determining her future reproductive health and success. Thus, a worldwide decline in menarcheal age (timing of first menstrual period may have serious long-term consequences. Early menarcheal timing (first menstrual period before age 12 can have a negative effect on fecundity, as well as the quality and quantity of offspring, and may consequently influence population growth or decline. In this paper, we apply an evolutionary framework to modern human health, and assess both proximate and ultimate consequences of declining menarcheal age. Examination of human reproductive health within an evolutionary framework is innovative and essential, because it illuminates the ultimate consequences of a declining age of menarche and facilitates new ways of thinking about the long-term and intergenerational transmission of health and disease; thus, an evolutionary framework lends itself to innovative public health and policy programs. In this paper, we examine whether or not early menarche is an alternative reproductive tactic that modern human females employ in response to a stressful environment, and whether or not early menarche is ultimately beneficial.

    Full Text Available PurposeTo examine the relationship between menarcheal age and anthropometric indices and menstrual irregularity in late adolescent girls in Seoul.MethodsWe surveyed 4,218 fertile adolescent girls between the ages of 16 and 18 years to determine their anthropometric indices and menarcheal age. Measurements were taken from June 2008 to October 2009 at seven girl's high schools in Seoul, Korea. Participants were offered self-report questionnaire as a survey tool that included questions on anthropometric indices (height, weight, waist circumference, menarcheal age, menstrual pattern, frequency of menstruation per year.ResultsThe participants were categorized into three groups based on menarcheal age: early menarche group (younger than 2 standard deviations [SD], mid menarche group (within ±2 SD, late menarche group (older than 2 SD. The mean age of early menarche group was 9.9±0.2 years, mid menarche group 12.5±0.9 years, late menarche group 15.1±0.3 years (P < 0.001. Heights were recorded as 160.4±5.2 cm, 161.8±4.9 cm, 162.3±4.7 cm in early, mid, and late menarche group, respectively (P = 0.001. Body mass index (BMI and waist circumference significantly were lager in early menarche group than mid and late menarche ones (P < 0.001. The menarcheal age had a positive correlation with height and negative correlations with weight, BMI, waist circumference (P < 0.001. The prevalence of oligomenorrhea was more frequent in late menarche group than early and mid menarche group.ConclusionThe menarcheal age have positive relationship with height and inverse relationship with BMI and waist circumference in late adolescent girls in Seoul. Late menarcheal girls are disposed to have menstrual irregularity compared to early menarcheal girls.

    A total of 194 adolescent girls were participated in this study. Early menarche was found in 22.68% of all subjects. There was no association between menarche status and daily macronutrients intake pattern and physical activity level score. Early menarche subjects had significantly higher BMI (p<0.001, CDC-percentile (p<0.001, WHO Z-score (p<0.001, and waist circumference values (p=0.02. Furthermore, early menarche subjects also had higher systolic blood pressure (p=0.035, total cholesterol level (p=0.028, LDL-cholesterol level (p=0.013, and triglyceride level (p=0.026. There was no association between menarche status and diastolic blood pressure, fasting blood glucose, HDL-C level, lipid profile ratio. In conclusion, early menarche is an important determinant factor of metabolic risks, and balance between dietary intake and physical activity level should be prioritized among them.

    Full Text Available Abstract Background Early age at menarche is associated with increased risk of metabolic syndrome in both China and the West. However, little is known about the impact of age at menarche and metabolic syndrome in South Asian women, including those from low-income country, where age at menarche is also falling. The aim of the present study was to investigate whether age at menarche is inversely associated with metabolic syndrome in Bangladeshi women, who are mostly poor and have limited access to and or poor health care facilities. Methods This community-based cross-sectional study was performed using 1423 women aged between 15–75 years from rural Bangladesh in 2009 and 2010. Metabolic syndrome was defined according to standard NCEP-ATP III criteria. Logistic regression was used to estimate the association between age at menarche and metabolic syndrome, with adjustment of potential confounding variables, including age, education, marital status, tobacco users, use of contraceptives and number of pregnancies. Results Early onset of menarche (13 years was found to be associated with a higher prevalence of metabolic syndrome (odds ratio=1.55; 95 % confidence interval =1.05-2.30. Age at onset of menarche was also inversely associated with prevalence of high triglycerides (P for trend P for trend = 0.01, but positively associated with prevalence of high fasting blood glucose (P for trend =0.02. However, no significant association was found between age at menarche, high blood pressure and elevated waist circumference. Conclusion Early onset of menarche might promote or trigger development of metabolic syndrome. Thus, knowledge of the history of age at onset of menarche may be critical in identifying women at risk of developing metabolic syndrome and those likely to benefit the most from early interventions.

  18. The Evolution of the Age at Menarche from Prehistorical to Modern Times.

    Menarche denotes the onset of the female reproductive capacity. The age that menarche occurs is mostly attributed to the interaction of genetics and various environmental factors. Herein, the author describes the evolution of the age at menarche from prehistoric to the present times. Data from skeletal remains suggest that in the Paleolithic woman menarche occurred at an age between 7 and 13 years, early sexual maturation being a trade-off for reduced life expectancy. In the classical, as well as in the medieval years, the age at menarche was generally reported to be at approximately 14 years, with a range from 12 to 15 years. A significant retardation of the age at menarche occurred in the beginning of the modern times, soon after the industrial revolution, due to the deterioration of the living conditions, with most studies reporting menarche to occur at 15-16 years. In the 20th century, especially in the second half of it, in the industrialized countries, the age at menarche decreased significantly, as a result of the improvement of the socioeconomic conditions, occurring at 12-13 years. In the present times, in the developed countries, this trend seems to slow down or level off. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    2017-06-17

    Background There is strong evidence that the mean age of menarche has declined over the last few decades in developed and developing countries. This is of a major concern because of its enormous public health implications. This study aimed to estimate the age of menarche in Kuwait and investigate the association between menarcheal age and academic performance among high school girls in Kuwait. Methods A cross-sectional study was conducted on randomly selected female high school students from private and public high schools in all governorates in Kuwait. Data on the age of menarche were collected by self-administered questionnaire from the students, while data on academic performance were extracted from the students' academic records. Results Of the 907 students we selected, 800 (88.2%) responded. The mean age of menarche was 12.33 [95% confidence interval (CI) 12.18-12.49] years. There was no evidence for significant association between age of menarche and students' academic performance before or after adjusting for potential confounders. Conclusion The calculated age of menarche among contemporary girls in Kuwait is similar to that of the girls in industrialized countries. Early menarcheal age is unlikely to lead to adverse behavior that may affect academic performance in our setting.

The aim of the present study was to determine the age at menarche and its related factors in school girls in Zanjan city, Iran.Materials and MethodsThis cross-sectional study was conducted on 1,500 healthy school girls between 6-17 years old who were selected on the basis of a multistage probability sampling. Age at menarche, birth weight, family size, Body Mass Index (BMI, fast food consumption, and physical activity, were recorded. Data were analyzed using SPSS version 16.0.ResultsOut of 1,500 students, 273 girls (18.2% had experienced menarche with a mean age of 12.6±1.6 (95% confidence interval [C]: 12.4-12.8, and a median age of 13 years. The prevalence of early menarche, was 10.3%, (95% CI: 6.6%-14.1%. A significant association between menarche and BMI, frequency of fast food consumption and birth rank was observed; however, we didn’t find a significant association between physical activity (P>0.05 and birth weight (P>0.05 with menarche. ConclusionThe mean age of menarche in our study was 12.6±1.6 years old, similar to other studies in Iran, and it was significantly associated with higher BMI.

    To date, no epidemiologic studies have examined the association of TCDD exposure and age at menarche. Three studies, however, have examined the relation of dioxin-like compounds to pubertal development, with inconsistent conclusions. A study of daughters of Michigan women who had consumed polybrominated biphenyls (PBB) in food in 1973, found an earlier age at menarche among daughters whose mothers had higher serum PBB levels 8. No differences were found in age at menarche of Taiwanese women who were exposed postnatally (but premenarche) to PCBs and PCDFs via consumption of contaminated rice oil (Yu-Cheng) compared to unexposed 9. In Flemish adolescents, there was no relation of age at menarche with current serum levels of dioxin-like compounds as measured by Chemical Activated LUciferase gene eXpression bioassay toxic equivalents (CALUX-TEQ) or individual PCB congeners 118, 153, and 180 10. On July 10, 1976, as a result of a chemical explosion, residents of Seveso, Italy experienced the highest levels of TCDD exposure in a human population. Twenty years later (1996-1998), the Seveso Women's Health Study (SWHS), a retrospective cohort study, was initiated to determine whether the women were at higher risk for reproductive disease. Among participants in SWHS, we have observed that TCDD levels are associated with an increase in menstrual cycle length among those who were premenarcheal at exposure, but not in those who were postmenarcheal at exposure 11. Consistent with animal studies 12, this suggests that females may be particularly susceptible to the effects of TCDD during early stages of development, e.g. in utero or pre-pubertal. Thus, here we examine the association of individual serum TCDD and age of menarche among women who were premenarcheal in 1976, at the time of explosion.

    Full Text Available Abstract Background Age at menarche is the reflection of cumulative pre-adolescent exposure of girls to either adverse environment such as food insecurity or affluent living conditions. Food insecurity could result in inadequate nutrient intake and stress, both of which are hypothesized to have opposing effects on the timing of menarche through divergent pathways. It is not known whether food insecure girls have delayed menarche or early menarche compared with their food secure peers. In this study we test the competing hypothesis of the relationship between food insecurity and age at menarche among adolescent girls in the Southwest Ethiopia. Methods We report on 900 girls who were investigated in the first two rounds of the five year longitudinal survey. The semi-parametric frailty model was fitted to determine the effect of adolescent food insecurity on time to menarche after adjusting for socio-demographic and economic variables. Results Food insecure girls have menarche one year later than their food secure peer (median age of 15 years vs 14 years. The hazard of menarche showed a significant decline (P = 0.019 as severity of food insecurity level increased, the hazard ratio (HR for mild food insecurity and moderate/severe food insecurity were 0.936 and 0.496, respectively compared to food secure girls. Stunted girls had menarche nearly one year later than their non-stunted peers (HR = 0.551, P Conclusion Food insecurity is associated with delay of age at menarche by one year among girls in the study area. Stunted girls had menarche one year later than their non-stunted peers. Age at menarche reflects the development of girls including the timing of sexual maturation, nutritional status and trajectory of growth during the pre-pubertal periods. The findings reflect the consequence of chronic food insecurity on the development and well-being of girls in the study area.

    Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45 ± 1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (pObese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

    To investigate the relationships between menarcheal timing and both menarcheal experience and attitudes toward menstruation in Mexican girls. Cross-sectional survey. Sample of adolescents attending 10 different public schools. Mexican postmenarcheal adolescents, aged 11-16 years. Participants answered 1 questionnaire about menarcheal experience and another about attitudes towards menstruation. Early maturers (menarche before 11 years) were more likely than average (menarche at 11 or 12 years) or late maturers (menarche at 13 or more years) to state they had not known what they should do at the moment they got their first period (P menstruating (P menstruation (P menstruation than their peers (P menstruation. Since these girls have limited or in some cases no time for preparation, they need special support. Copyright © 2014 North American Society for Pediatric and Adolescent Gynecology.

    This study explored the relationship between early and current menstrual experiences. The primary hypothesis was that women who reported positive menarcheal experiences (including menstrual education and menarche) would tend to report positive current menstrual attitudes, experiences, and/or behaviors, and vice versa for women who reported negative menarcheal experiences. In this survey-based study, college-aged women (n = 327) were screened by completing a questionnaire concerning their menarcheal experiences. Women who had extremely negative ("negative group," n = 46) or extremely positive ("positive group," n = 38) early menstrual experiences returned to complete questionnaires concerning current menstrual attitudes, experiences, and behaviors. Early and current menstrual experiences were most strongly associated in the domain of menstrual attitudes. Women in the negative group reported more negative menstrual attitudes than did women in the positive group. There were additional associations between early menstrual experiences and measures of body image and health behaviors. Positive group participants reported more positive body image and better general health behaviors. Results suggest that early menstrual experiences may be related to menstrual experiences later in life. This study invites further investigation of the psychology of menstruation and suggests connecting menstruation with other women's health issues.

    Polycystic ovarian syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism and chronic anovulation, which affects 5%-10% of reproductive-age women. Diagnosis of adult patients with PCOS is made easily with clinical and laboratory methods and the anti-Müllerian hormone (AMH) level are accepted as a good indicator. However, there is still no complete consensus on the diagnosis of PCOS in adolescents. Prospective cohort study, December 2013 to November 2014. The study was conducted on adolescent girls with oligomenorrhea, with at least 2 years since menarche. The study group consisted of adolescent girls with complete PCOS and incomplete PCOS. A control group was formed of healthy adolescent girls. Complete PCOS was diagnosed according to the Rotterdam criteria, as the presence of all the following characteristics: oligomenorrhea, hyperandrogenism, and polycystic ovarian morphology on ultrasound image. Incomplete PCOS was accepted as "oligomenorrhea and polycystic ovarian morphology," or "oligomenorrhea and hyperandrogenism." All patients underwent a physical examination and the anthropometric assessments, insulin resistance, and acanthosis nigricans were recorded. It was also noted whether or not the patient had an acne score. The Ferriman-Gallwey score was applied to evaluate hirsutism. The results of this study showed that no statistically significant difference was found between the PCOS and incomplete PCOS groups and the control group with respect to AMH levels. The use of adult-specific diagnostic methods in adolescence might result in an incomplete diagnosis and inadequate treatment plan. Although the serum AMH level clearly facilitates the diagnosis of PCOS, the use of the AMH level in adolescence in PCOS diagnosis is still controversial and further studies are needed.

    The aim of this study was to evaluate potential risk factors, including non-communicable diseases, for morbid obesity in women between 20 and 49 years of age. We performed a case-control study with 110 morbidly obese women and 110 women with adequate weight who were matched by age and with a 1:1 case to control ratio. All women were between 20 to 49 years old and non-menopausal. Possible risk factors were evaluated through a self-report questionnaire assessing socio-demographic, obstetric and gynecological characteristics, presence of non-communicable diseases and habits. Multiple logistic regression was used to estimate the odds ratio with respective confidence intervals. Menarche under 12 years old, teenage pregnancy and lower educational level were shown to be risk factors for morbid obesity among women of reproductive age. Incidences of non-communicable diseases (diabetes, hypertension, dyslipidemia, liver disease, lung disease, thyroid dysfunction, and joint pain) were increased in women with morbid obesity. Early menarche, teenage pregnancy and low education level are risk factors for the occurrence of morbid obesity in women of reproductive age. Some non-communicable diseases were already more prevalent in women with morbid obesity even before 50 years of age.

To investigate the relation of osteoporosis in postmenopausal mexican women with multiparity and age of menarche. Transversal, retrospective and analytical study. Non-probabilistic sampling technique was performing with users women of the IMSS in San Luis Potosí. Reproductive history and age of menarche were obtained by the addition of these items to the previously validated Albrand questionnaire. Women were divided into groups according to the number of pregnancies in: normal parity (0 to 3 childbirths) conformed by 112 patients (46%) and multiparity (> or = 4 pregnancies), 131 women (54%). In relation to menarche with an average of 12.98 years, from this number we divided them in: early menarche (before the age of 13) and late menarche (at 13 years of age or after). It was measured bone mineral density with dual distal forearm x-ray absorptiometry to all patients. 243 women were studied, with an average of age of 55.92, rank 31 to 80 years. Using the criteria, of the World Health Organization, 18% of posmenopausal women had osteoporosis, 39% had osteopenia and 41% had bone normality. No association was found between the number of deeds and osteoporosis. Additionally we observed that the women who had 4 or more children were older than the other women. average 57.42 against 54.16. Also there was significant negative correlation (r = -0.43) between age and densitometry. In addition we found that an age greater to 13 years in the appearance of the menarche was related to osteoporosis (OR 4.46; p = 0.035). In posmenopausal women a menarche at the age of 13 years or after is a risk factor for osteoporosis.

    Full Text Available Background In recent decades, girls have experienced menarche at earlier ages, which may have negative effects on health. Exposure to audio-visual media and other factors may influence the age at menarche, although past studies have produced inconsistent results. Objective To assess for relationships between the age at menarche and audio-visual media exposure, socio-economic status, nutritional status, physical activity, and psychosocial dysfunction in adolescent girls. Methods This cross-sectional study was conducted from August to October 2015 in students from two integrated Islamic junior high schools in Medan, North Sumatera. There were 216 students who met the inclusion criteria: aged 10-16 years and experienced menarche. They were asked to fill out questionnaires that had been previously validated, regarding their history of exposure to audio-visual media, physical activity, and psychosocial dysfunction. The data were analyzed by Chi-square and Fisher’s exact tests in order to assess for relationships between audio-visual media exposure and other potential factors with the age at menarche. Results Of 261 female students at the two schools, 216 had undergone menarche, with a mean age at menarche of 11.6 (SD 1.13 years. There was no significant relationship between age at menarche and audio-visual media exposure (P=0.68. Also, there were no significant relationships between factors such as socio-economic and psychosocial status with age at menarche (P=0.64 and P=0.28, respectively. However, there were significant relationships between earlier age at menarche and overweight/obese nutritional status (P=0.02 as well as low physical activity (P=0.01. Multivariate logistic regression analysis showed that low physical activity had the strongest influence on early menarche (RP=2.40; 95%CI 0.92 to 6.24.

    Full Text Available Abstract Background Menarche delay has been reported in adolescent females with type 1 diabetes (T1DM, perhaps due to poor glycemic control. We sought to compare age at menarche between adolescent females with T1DM and national data, and to identify factors associated with delayed menarche and menstrual irregularity in T1DM. Methods This was a cross-sectional study and females ages 12- 24 years (n = 228 with at least one menstrual period were recruited during their outpatient diabetes clinic appointment. The National Health and Nutrition Examination Survey (NHANES 2001-2006 data (n = 3690 for females 12-24 years were used as a control group. Results Age at menarche was later in adolescent females with T1DM diagnosed prior to menarche (12.81 +/- 0.09 years (mean+/- SE (n = 185 than for adolescent females diagnosed after menarche (12.17 0.19 years, p = 0.0015 (n = 43. Average age of menarche in NHANES was 12.27 +/- 0.038 years, which was significantly earlier than adolescent females with T1DM prior to menarche (p p = 0.77. Older age at menarche was negatively correlated with BMI z-score (r = -0.23 p = 0.0029 but not hemoglobin A1c (A1c at menarche (r = 0.01, p = 0.91. Among 181 adolescent females who were at least 2 years post menarche, 63 (35% reported usually or always irregular cycles. Conclusion Adolescent females with T1DM had a later onset of menarche than both adolescent females who developed T1DM after menarche and NHANES data. Menarche age was negatively associated with BMI z-score, but not A1c. Despite improved treatment in recent decades, menarche delay and high prevalence of menstrual irregularity is still observed among adolescent females with T1DM.

    Full Text Available Introduction: Biological, psychosocial, cognitive, emotional and social changes begin during puberty and continue throughout adolescence. The age at which a female reaches sexual maturity is critical in determining her future reproductive health and success. The aim of the study was to assess the average age of sexual feeling and menarche among the adolescent girls and its determinants. Methods: Three hundred fifty five respondents were selected through simple random sampling from three secondary schools (namely Sunrise Boarding School, Swaraswati Secondary School and Gyanjyoti Samudayak Bidhyalaya in Palpa for the cross-sectional study. Structured interview schedule was used to collect information. Data was tabulated in Microsoft Excel spreadsheet and analyzed with SPSS-16. Results: Most of the girls (44.8% attained menarche at 12 years (M = 12.4, SD = 1.11. Age at menarche was more likely before 13 years of age when the age of onset of sexual feeling was earlier than 12 years of age, in students than in domestic workers and if they are living with parents than in those not living with parents. Conclusion: The average age of menarche among the adolescent girls was 12.40 years and it could be influenced by age of sexual feeling, occupation and living status of girls.

    Full Text Available The objective of the present study was to determine median age at menarche and the influence of familial instability on maturation. The sample included 7047 girls between the ages of 9 and 17 years from Tuzla Canton. The girls were divided into two groups. Group A (N=5230 comprised girls who lived in families free of strong traumatic events. Group B (N=1817 included girls whose family dysfunction exposed them to prolonged distress. Probit analysis was performed to estimate mean menarcheal age using the Probit procedure of SAS package. The mean menarcheal age calculated by probit analysis for all the girls studied was 13.07 years. In girls from dysfunctional families a very clear shift toward earlier maturation was observed. The mean age at menarche for group B was 13.0 years, which was significantly lower that that for group A, 13.11 years (t=2.92, P<0.01. The results surveyed here lead to the conclusion that girls from dysfunctional families mature not later but even earlier than girls from normal families. This supports the hypothesis that stressful childhood life events accelerate maturation of girls.

Methods: a cross-sectional, observational and descriptive study was conducted in "Jose Maria Heredia" junior high school from June 2010 to January 2011. The population was made up of 85 adolescents, who were asked about menarche, were anthropometrically measured and searched for acanthosis nigricans. Results: the average age of female adolescents was 12.05 years. Menarche was experienced by 63.5% of them and the average age of onset was 11.00±0.801 years. In this group, 17.6 % presented with overweight, 34.1 % with abdominal adiposity and 12.9 % had acanthosis nigricans, all of these factors statistically associated with the onset of menarche. Conclusions: most of the female adolescents experienced menarche at early ages; they were Caucasians and showed a high risk of developing overweight, abdominal obesity and clinical signs of insulin-resistance. The onset of menarche was not affected by low birthweight.

    Menarcheal age is considered to be an indicator of puberty. There is a lack of information on menarcheal age in Tehranian girls, in comparison to that of their mothers. This cross-sectional study was aimed at comparing the age of menarches between two generations. The subjects were 812 (406 daughters and 406 mothers) chosen from among 15005 participants of the longitudinal Tehran Lipid and Glucose Study. Demographic information and the age of menarche were recorded in a questionnaire. We have considered a minimal of 25 years duration to be one generation. Distribution of the menarcheal age and linear regression were performed. The mean age of menarche in daughters and their mothers were 13.2+-1.4 and 13.6+-1.5 years, respectively. There was significant correlation between the mother and daughter menarcheal age (r=0.25, P<0.002). 25th, 50th and 75th percentiles for menarcheal ages in daughters and their mothers were 12.2, 13.1, 14.1 and 12.7, 13.5, 14.5 years respectively. Minimum and maximum ages of menarche were the same (10 and 18 years) in the two groups. We found a decrease in the average menarcheal age during 25 years (one generation) similar to the results of other studies. (author)

    Context: Delayed menarche is associated with subsequent reproductive and skeletal complications. Previous research has found delayed growth and pubertal maturation with type 1 diabetes and with poor glycemic control. The effect of diabetes management on menarche is important to clarify because tighter control might prevent these complications. Objective: To investigate age at menarche in young women with type 1 diabetes, and examine the effect of diabetes management (e.g. total glycosylated hemoglobin (GHb) level, number of blood glucose checks, insulin therapy intensity, insulin dose) on age at menarche in those diagnosed before menarche. Design: The Wisconsin Diabetes Registry Project is a follow-up study of a type 1 diabetes population-based incident cohort initially enrolled 1987 – 1992. Setting: Twenty-eight counties in south-central Wisconsin. Patients or Other Participants: Recruited through referrals, self-report, and hospital/clinic ascertainment. Individuals with newly diagnosed type 1 diabetes, <30 years old, were invited to participate. Of 288 young women enrolled, 188 reported menarche by 2002; 105 were diagnosed before menarche. Interventions: Not applicable. Main Outcome Measure: Age at menarche. Results: Mean age at menarche was 12.78 years, compared to 12.54 years in the United States (p = 0.01). Ages at menarche and diagnosis were not associated. For those diagnosed before menarche, age at menarche was delayed 1.3 months with each one percent increase in mean total GHb level in the three years prior to menarche. Conclusions: Age at menarche was moderately delayed in young women with type 1 diabetes. Delayed menarche could potentially be minimized with improved GHb levels. PMID:16204372

    Menarche is an important milestone in the development of female adolescents. The study assessed the age at menarche using recall, its seasonality, and association with marital and nutritional status (using mid-upper arm circumference [MUAC]) among 3,923 female adolescents aged 12-19 years in a rural area of Bangladesh. At the time of assessment, most (88%) adolescents had attained menarche at the mean (standard deviation [SD]) age of 12.8 (1.4) years. Age of onset of menarche among married adolescents (13%) occurred earlier than in those who were unmarried (12.6 +/- 1.3 years vs 12.9 +/- 1.4 years, p < 0.01). Age at menarche was negatively associated with MUAC after adjusting for age and marital status (beta = -0.10, p < 0.01). More than 50% of the adolescents had an onset of menarche during winter (chi2 = 634.97; p < 0.001), with peaks in December and January. In this rural population, the current age at menarche was found to be slightly lower than the previous estimates of 13.0 years in Bangladesh. An early onset of menarche was associated with season and better nutritional status of the female adolescents and may be associated with early marriage.

    Introduction. Menarche is a critical time point in a woman's reproductive system development; exposures at menarche may influence maternal health. Living in a poorer neighborhood is associated with adult obesity; however, little is known if neighborhood factors at menarche are associated with prepregnancy obesity. Methods. We examined the association of neighborhood-level poverty at menarche with prepregnancy body mass index category in 144 pregnant African-American women. Address at menarche was geocoded to census tract (closest to year of menarche); neighborhood-level poverty was defined as the proportion of residents living under the federal poverty level. Cumulative logistic regression was used to examine the association of neighborhood-level poverty at menarche, in quartiles, with categorical prepregnancy BMI. Results. Before pregnancy, 59 (41%) women were obese. Compared to women in the lowest neighborhood-level poverty quartile, women in the highest quartile had 2.9 [1.2, 6.9] times higher odds of prepregnancy obesity; this was slightly attenuated after adjusting for age, marital status, education, and parity (odds ratio: 2.3 [0.9, 6.3]). Conclusions. Living in a higher poverty neighborhood at menarche is associated with prepregnancy obesity in African-American women. Future studies are needed to better understand the role of exposures in menarche on health in pregnancy.

    The age at menarche reflects a pubertal girl's physiologic maturity. The aims of this study were to evaluate the relationship between the age at menarche and skeletal maturation in female orthodontic patients. Hand-wrist radiographs and lateral cephalometric radiographs from 304 adolescent female subjects (age, 8-18.9 years) were selected from the files of the Department of Orthodontics, National Taiwan University Hospital (NTUH). Hand-wrist bone maturation stages were assessed using the NTUH Skeletal Maturation Index (NTUH-SMI). Cervical vertebral maturation stages (CVMS) were determined using the latest CVMS Index. Menarcheal ages were self-reported by the patients and verified by the patients' mothers. The relationships between the NTUH-SMI or CVM stages and menarcheal status were investigated. More than 90% of the 148 subjects who had already attained menstruation had skeletal maturation beyond the NTUH-SMI stage four or CVMS III. However, the subjects who had never experienced menarche mostly had skeletal maturation before NTUH-SMI stage five or CVMS IV. During the period of orthodontic treatment, 19 females experienced their menarche. The mean age at menarche for the 167 female patients in total was 11.97 years. In average, menarche occurred between NTUH-SMI stages four and five or between CVM stages III and IV. The percentage of girls with menses increased from 1.2% at age 9 to 6.6% at age 10, 39.5% at age 11, 81.4% at age 12, 97% at age 13, and 100% at age 14. Compared with the results obtained 20 years previously, we found a downward shift of 0.47 years per decade for the mean age at menarche in female orthodontic patients. The majority of female orthodontic patients have passed the pubertal growth spurt when they experience their menarche. Menarche usually follows the pubertal growth spurt by about 1 year and occurs after NTUH-SMI stage four or CVMS III.

    Full Text Available Objective. The aim of this study was to determine the effect of psychosocial factors on the age at menarche of girls in Federation of Bosnia and Herzegovina (FBH. Subjects and methods. A cross-sectional study was conducted from September 2002 to May 2003 in all Cantons of the FBH. The random stratified sample included 19.803 girls aged 9.0 to 17.5 years. Data were collected using the status quo method. Probit analysis was used to estimate median age at menarche and 95% confidence intervals. Results. The present study shows that menarche occurred significantly earlier (p<0.05 in girls from dysfunctional families (median: 12.99 years, 95% confidence interval: 12.93-13.05 than in girls who grew up in intact families (median: 13.04 years, 95% confidence interval: 13.01-13.07. Analyzing separately the impact of each of family stressors on age at menarche, we found that menarcheal age was significantly lower in girls from single-mother families, whose parents are divorced, whose one parent is died and where alcoholism in family is present than in girls from intact families. Maturation was found to be earlier in girls from dysfunctional families then in those from intact families after the influence of place of residence and sibship size was eliminated. Conclusion. From our research we can conclude that the girls from dysfunctional families reached earlier age at menarche than their peers who grew up in normal families, and that this effect did not disappear after controlling for socioeconomic variables.

    To compare the age at menarche obtained by recall method according to the time elapsed since the event, in order to verify the importance of the recall bias. Were evaluated 1,671 girls (7-18 years) at schools in Campinas-SP regarding the occurrence of menarche by the status quo method (menarche: yes or no) and the recall method (date of menarche, for those who mentioned it). The age at menarche obtained by the status quo method was calculated by logit, which considers the whole group, and the age obtained by the recall method was calculated as the average of the mentioned age at menarche. In this group, the age at menarche was obtained by the difference between the date of the event and the date of birth. Girls who reported menarche (883, 52.8%) were divided into four groups according to the time elapsed since the event. To analyze the results, we used ANOVA and logistic regression for the analysis, with a significance level of 0.05. The age at menarche calculated by logit was 12.14 y/o (95% CI 12.08 to 12.20). Mean ages obtained by recall were: for those who experienced menarche within the previous year 12.26 y/o (±1.14), between > 1-2 years before, 12.29 y (±1.22); between > 2-3 years before, 12.23 y/o (±1.27); and more than 3 years before, 11.55y/o (±1.24), p recall method was similar for girls who menstruated within the previous 3 years (and approaches the age calculated by logit); when more than 3 years have passed, the recall bias was significant.

    Full Text Available OBJECTIVE: To examine the relationship between growth patterns in early childhood and the onset of menarche before age 12. METHODS: The study included 2,083 women from a birth cohort study conducted in the city of Pelotas, Southern Brazil, starting in 1982. Anthropometric, behavioral, and pregnancy-related variables were collected through home interviews. Statistical analyses were performed using Pearson's chi-square and chi-square test for linear trends. A multivariable analysis was carried out using Poisson regression based on a hierarchical model. RESULTS: Mean age of menarche was 12.4 years old and the prevalence of menarche before age 12 was 24.3%. Higher weight-for-age, height-for-age, and weight-for-height z-scores at 19.4 and 43.1 months of age were associated with linear tendencies of increased prevalence and relative risks of the onset of menarche before age 12. Girls who experienced rapid growth in weight-for-age z-score from birth to 19.4 months of age and in weight-for-age or height-for-age z-scores from 19.4 to 43.1 months of age also showed higher risk of menarche before age 12. Higher risk was seen when rapid growth in weight-for-age z-score was seen during these age intervals and the highest risk was found among those in the first tertile of Williams' curve at birth. Rapid growth in weight-for-height z-score was not associated with menarche before age 12. CONCLUSIONS: Menarche is affected by nutritional status and growth patterns during early childhood. Preventing overweight and obesity during early childhood and keeping a "normal" growth pattern seem crucial for the prevention of health conditions during adulthood.OBJETIVO: Evaluar la relación entre patrones de crecimiento en la infancia precoz y ocurrencia de menarca antes de 12 años de edad.

    Precocious menarche currently affects 1 in 5000 girls and likely to occur as many as 10 times and possess greater risk to the emergence of cancer in women. The aim of this research is to determine the relationship of nutrition status and lipid profile with precocious menarche occurrence onstudents of primary school in Makassar city. The design of this research was cross sectional design. The samples werethe students of grades IV, V and VI who have already menarche occurrence as many as 20 studentscollected with purposive sampling. The data were analyzed with Mann Whitney U test. The results indicate that there are 17 students (85%) do not undergoprecocious menarche, normal nutrition status is 11 persons (55%), normal cholesterol levelis 12 persons (60%), and level of normal LDL = 19 persons (95%). While the respondents who undergo precocious menarche is 3 persons (15%), fat nutrition status is 9 persons (45%), cautious cholesterol level is 8 persons (40%) and cautious LDL level is 1 person (5%). Based on Mann Whitney U test, there is relationship between nutrition status and precocious menarche occurrence (p = 0.043) and there is correlation of total cholesterol and LDLcholesterollevelswith precocious menarche (p = 0.025) and (p = 0.017). The decrease of knowledge about health of reproduction can be promoted in school by making cooperation with nutritionist to give information to parents and students of primary schools about good and healthy food.

    Full Text Available Background. The acceleration of pubertal development is an important medical and social problem, as it may result in increased morbidity and mortality in later life. This systematic review summarizes relevant data about nongenetic factors, which contribute to age at menarche (AAM, and suggests those which may be the most important. Methods. The available literature from 1980 till July 2013 was searched using PubMed and Google Scholar databases. Finally, 154 papers were selected for the analysis. Results. Environmental factors, which may affect AAM, vary in populations of different ethnicity. The prenatal, infancy, and early childhood periods are the most susceptible to these factors. Body weight, high animal protein intake, family stressors (e.g., single parenting, and physical activity seem to influence AAM in most populations. Conclusions. The data about influence of nongenetic factors on AAM are still inconsistent. The factors affecting prenatal and early childhood growth seem to have a larger effect on further sexual maturation. Further studies are needed in order to validate the association between other environmental determinants and AAM in different ethnical groups.

    Full Text Available The aim of this study is to determine whether regular physical activity during early puberty is influential in preventing early menarche. This cross sectional study was carried out on 102 post-menarcheal girls aged 11–20 (14.79±0.33. 51 of them were already engaged in competitive sport activities prior to the onset of menstruation (group 1, while the others got engaged in such activities after the onset of menstruation (group 2. All participants provided the year and the month of their first menstrual period. First, we estimated the equality of dispersion between the two groups, by conducting Two Samples for Variances F-test. Second, because no homogeneity of variances between groups was found, they were compared by using Two Samples Assuming Unequal Variances t-test. The difference between groups is statistically significant, as the t statistics (=2.883 is greater than both critical t statistics (one-tail=1.664 two-tail=1.990 and the p value less than 0.05 in both cases (one-tail=0.002 two-tail=0.005. None of the girls in the first group starts to menstruate before 11 years of age and 90% of them are menstruating by age 14, with a median age of 12.95±0.35 years. Age of menarche is lower in the second group with a median age of 12.25±0.31 years, thus approximately 8 months lower than median age for the first group. 11.76% of the girls in the second group start to menstruate before 11 years of age and 90% of them are menstruating by age 13. It is rather, the decline in early matures among those engaged in regular physical activity prior to the onset of menses, that makes the statistically significant correlation between physical activity and age at menarche practically meaningful. Relatively early matures (<11 years have been found to be slightly shorter but up to 5.5 kg heavier in adulthood than are late matures. In addition, a relatively young age at menarche has been associated with an increased risk for breast cancer and spontaneous

    The early onset of menarche is related to the adulthood risk of cardiovascular (CV) disease. This study examines the relation of early onset of menarche to carotid artery intima-media thickness (IMT), which is a surrogate marker of CV disease, among asymptomatic young adult women in a black-white community. A cohort of 461 women (31% black, 69% white) aged 24 to 43 years (mean of 35.6 years) were participants in the Bogalusa Heart Study. The age at menarche was retrospectively collected. In addition to CV risk factor variable measurements B-mode ultrasound images of the far walls of carotid artery segments were obtained. The multivariate linear regression model along with mediating effect by Sobel test was applied to analyze menarcheal age effect on carotid artery IMT, adjusting for covariates. Waist to height ratio was significantly greater (P = .01) in early menarcheal age (women. Homeostasis model assessment of insulin resistance (HOMA-IR) was significantly greater (P = .01) in early menarcheal age (women and also similar direction in black women. Internal carotid artery IMT was the same in early menarcheal age (women but higher (P = .02) in black women. Given as previously mentioned these different associations, the mediation analysis by race was performed. The effect of early menarcheal age (women after adjusting for parental education and age. The mediating effect of waist to height ratio (Sobel test = -2.26 and P = .02) and HOMA-IR (Sobel test = -1.85 and P = .06) on internal carotid artery IMT was noted in white women.

    Full Text Available Abstract Background Age at menarche is considered a reliable prognostic factor for idiopathic scoliosis and varies in different geographic latitudes. Adolescent idiopathic scoliosis prevalence has also been reported to be different in various latitudes and demonstrates higher values in northern countries. A study on epidemiological reports from the literature was conducted to investigate a possible association between prevalence of adolescent idiopathic scoliosis and age at menarche among normal girls in various geographic latitudes. An attempt is also made to implicate a possible role of melatonin in the above association. Material-methods 20 peer-reviewed published papers reporting adolescent idiopathic scoliosis prevalence and 33 peer-reviewed papers reporting age at menarche in normal girls from most geographic areas of the northern hemisphere were retrieved from the literature. The geographic latitude of each centre where a particular study was originated was documented. The statistical analysis included regression of the adolescent idiopathic scoliosis prevalence and age at menarche by latitude. Results The regression of prevalence of adolescent idiopathic scoliosis and age at menarche by latitude is statistically significant (p Conclusion Late age at menarche is parallel with higher prevalence of adolescent idiopathic scoliosis. Pubarche appears later in girls that live in northern latitudes and thus prolongs the period of spine vulnerability while other pre-existing or aetiological factors are contributing to the development of adolescent idiopathic scoliosis. A possible role of geography in the pathogenesis of idiopathic scoliosis is discussed, as it appears that latitude which differentiates the sunlight influences melatonin secretion and modifies age at menarche, which is associated to the prevalence of idiopathic scoliosis.

    The objective of the present study was to determine median age at menarche and the influence of familial instability on maturation. The sample included 7047 girls between the ages of 9 and 17 years from Tuzla Canton. The girls were divided into two groups. Group A (N=5230) comprised girls who lived in families free of strong traumatic events. Group B (N=1817) included girls whose family dysfunction exposed them to prolonged distress. Probit analysis was performed to estimate mean menarcheal age using the Probit procedure of SAS package. The mean menarcheal age calculated by probit analysis for all the girls studied was 13.07 years. In girls from dysfunctional families a very clear shift toward earlier maturation was observed. The mean age at menarche for group B was 13.0 years, which was significantly lower that that for group A, 13.11 years (t=2.92, Pdysfunctional families mature not later but even earlier than girls from normal families. This supports the hypothesis that stressful childhood life events accelerate maturation of girls.

    Age at menarche is an important determinant of hormonal-related neoplasia and other chronic diseases. Spatial and temporal variations in age at menarche have been observed in industrialised countries and several environmental factors were reported to have an influence. We examined geographical variations in self-reported age at menarche and explored the effects of both latitude and ultraviolet radiation (UVR) dose on the onset of menarche in 88,278 women from the French E3N cohort (aged 40-65 years at inclusion). The mean age at menarche was 12.8 years. After adjustment for potential confounders (birth cohort, prematurity, birth weight and length, father's income index, body silhouette in childhood, food deprivation during World War II, population of birthplace, number of siblings, breastfeeding exposure and indoor exposure to passive smoking during childhood), latitude and UVR dose (annual or spring/summer) in county of birth were significantly associated with age at menarche (P(trend) < 0.0001). Women born at lower latitudes or in regions with higher annual or spring/summer UVR dose had a 3- to 4-month earlier menarche than women born at higher latitudes or in regions with lower UVR. On a continuous scale, a 1° increment in latitude resulted in a 0.04-year older age at menarche [95% confidence interval (CI): 0.03, 0.05], whereas a 1-kJ/m(2) increment in annual UVR dose resulted in a 0.42-year younger age at menarche (95% CI: -0.55, -0.29). These data further suggest that light exposure in childhood may influence sexual maturation in women.

    This study was conducted to identify and describe symbolic themes of menarche. The qualitative case study design was used with a purposive sample of 30 participants (15 mothers and their 15 daughters) in answering 2 questions: (a) How do 9- and 10-year-old African American girls view the meaning of their menarcheal flow?, and (b) How do African American mothers view the meaning of menarche? Data were collected through interviews 2 to 5 days after completion of menarche. A cross-case comparison analysis of the interviews revealed 4 themes: (a) vaginal bleeding, (b) sexual maturation, (c) premenarcheal sexual activity, and (d) sexual payback to fathers. With the exception of the latter all themes were supported in earlier studies of Euro-American girls. These findings indicate the need for further research addressing self-concept at menarche, impact of menarche on family relationships, and views of fathers about sexual payback as a symbol of menarche.

    Full Text Available Objective: Downward shifts in the mean menarcheal age and earlier emergence of permanent second molars have been observed worldwide during the past few decades. A positive correlation between the two would make menarche a biomarker for permanent second molar eruption or vice versa, making it a simple tool for monitoring oral status of adolescent girls. This study was conducted to find a correlation between attainment of menarche and eruption status of permanent second molars in girls aged 10-13 years. Material and Methods: A cross-sectional descriptive study was conducted on 470 female students from six randomly selected schools who consented to participate in the interview and oral examination. Data were analyzed using the Chi square (X2 test with a p-value of < 0.05 considered statistically significant. Results: Significant differences existed within the age groups with regard to attainment of menarche (p = 0.000 and eruption status of second molars (p = 0.000 for all four teeth. However, no correlation could be found between attainment of menarche and eruption status of the permanent second molars. Conclusion: Although this study failed to find a correlation between the two variables, a population based multicentric survey may give a concrete conclusion on this issue.

    A woman’s age at menarche (first menstrual period) and her age at menopause are the alpha and omega of her reproductive years. The timing of these milestones is critical for a woman’s health trajectory over her lifespan, as they are indicators of ovarian function and aging. Both early and late timing of either event are associated with risk for adverse health and psychosocial outcomes. Thus, the search for a relationship between age at menarche and menopause has consequences for chronic disease prevention and implications for public health. This article is a review of evidence from the fields of developmental biology, epidemiology, nutrition, demography, sociology, and psychology that examine the menarche–menopause connection. Trends in ages at menarche and menopause worldwide and in subpopulations are presented; however, challenges exist in constructing trends. Among 36 studies that examine the association between the two sentinel events, ten reported a significant direct association, two an inverse association, and the remainder had null findings. Multiple factors, including hormonal and environmental exposures, socioeconomic status, and stress throughout the life course are hypothesized to influence the tempo of growth, including body size and height, development, menarche, menopause, and the aging process in women. The complexity of these factors and the pathways related to their effects on each sentinel event complicate evaluation of the relationship between menarche and menopause. Limitations of past investigations are discussed, including lack of comparability of socioeconomic status indicators and biomarker use across studies, while minority group differences have received scant attention. Suggestions for future directions are proposed. As research across endocrinology, epidemiology, and the social sciences becomes more integrated, the confluence of perspectives will yield a richer understanding of the influences on the tempo of a woman

    It is suggested that vitamin D level and age at menarche are related to each other, and the prevalence of low vitamin D status and early menarche in women is increasing worldwide. Moreover, several studies revealed that both of them are associated with metabolic syndrome (MetS). Therefore, we hypothesized that there are significant associations among vitamin D status, age at menarche, and MetS and that the relationships differ according to menstrual state. We assessed whether the association among MetS, vitamin D, and menarche age is different between premenopausal and postmenopausal women and whether there is a change in risk of MetS according to vitamin D level in different age-at-menarche groups. We used data from the Korea National Health and Nutrition Examination Survey, using 1:1 age-matching for this cross-sectional study. Individuals were stratified into 25-hydroxyvitamin D (25[OH]D) levels (deficient, D level, was associated with risk of MetS (odds ratio [95% confidence interval], 1.65 [1.18-2.33]). In contrast, in postmenopausal women, vitamin D deficiency, not age at menarche, was associated with risk of MetS (1.39 [1.03-1.87]). In a stratified analysis regarding interactions of a change in risk of MetS according to vitamin D level in different ages at menarche, vitamin D deficiency was significantly associated with the risk of MetS (1.36 [1.01-1.86]), but this was only in the average-age-at-menarche group. This study suggests that the time of entry into puberty for women may be an important factor in the development of MetS in adulthood, and vitamin D status in women at average menarche age may contribute to the development of MetS.

    The main aim of the study was to assess the influence of biological maturity at birth on growth processes in the subsequent years and during puberty in girls. The material of this study comes from the outpatient clinic cards and cross-sectional research on girls from the province of Wielkopolska in Poland. It includes data of 527 girls. The influence of perinatal maturity on body weight in the later stages of ontogeny was determined with the use of the Kruskal-Wallis test and the Mann-Whitney U test. In order to determine the relationship between perinatal maturity and age at menarche, the survival analysis module was used. The results show a diverse influence of perinatal maturity on the values of body weight achieved in later years of life. The indicated predictive factors included both birth weight and gestational age. In the examined girls menarche occurred between the 10th year and the 17th year of life (X¯=12.87, s=1.26; Me=13 years). The comparison showed a significant variation in age at menarche depending on the length of pregnancy (log-rank χ(2)(2)=27.068, p0.05). Remote prognoses as to the postnatal development of preterm-born children and/or children with low birth weight indicate adverse influence of these variables on age at menarche. Perinatal biological maturity of a newborn conditions the course of postnatal development. Copyright © 2012 Elsevier GmbH. All rights reserved.

    The aim of this study was to explore the relationship between age at menarche and age at first episode of psychosis, as well as clinical severity and outcome, in a population of women with first-episode psychosis. Clinical and socio-demographical data, age at menarche and at first-episode psychosis, parental history of psychosis and cannabis-use habits were obtained from 42 subjects with a first episode of psychosis. Positive and Negative Syndrome Scale, Clinical Global Impression, Global Assessment Function, Disability Assessment Schedule, Wechsler Adult Intelligence Scale and Wechsler Intelligence Scale for Children, European Quality of Life, and Lewis and Murray Obstetric Complication Scales were administered. Statistical analysis was performed by means of zero-order correlations and Mann-Whitney U and Kruskal-Wallis tests using SPSS version 17.0. We found no significant correlation between age at menarche and age at first-episode psychosis, or with the clinical scores performed. We observed that subjects with earlier age at menarche had more parental history of psychosis. Our negative results do not support the theory of a possible protective role of oestrogen, which seems to be more complex than previously thought. We would suggest that further research is needed to investigate developmental influences of sex steroids on the onset of psychosis and potentially therapeutic benefits based upon oestrogen. © 2014 Wiley Publishing Asia Pty Ltd.

    Purpose : This study was done to analyze survivals, patterns of failure, and complications of early uterine cervix cancer after curative radiotherapy. Methods and Materials : Eighty patients with uterine cervix cancer FIGO Stage IB (48 cases) and Stage IIA (32 cases) treated with radiotherapy were analyzed retrospectively. Patients were treated from November 1985 to May 1993, and minimum follow up period was 24 months. and 6 cases were lost to follow up. All of them were treated with external radiotherapy and different fractions of high dose rate intracavitary radiotherapy. Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. Results : Overall 5 year survival rate and relapse free survival rate were 72.3%, and 72.8% respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months. Late complication rate of bladder and rectum were 8.8%, 15% respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. Conclusion : These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients, To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed

    Full Text Available The number of cases of breast cancer is increasing every year and it’s a serious health problem in the world, including in Indonesia. Breast cancer is type of cancer that is most dominant in Indonesia. High estrogen exposure is one of factor that can increase the risk of breast cancer in women. This study was conducted to determine the relationship of estrogen exposure through the use of hormonal contraceptives and age of menarche with breast cancer incidence in women. Type of this study is observational analytic and use case control design. All of women breast cancer patients of Dr. Soetomo Hospital in 2013 were the population of case. All of woman non breast cancer patients who done breast examination at Dr Soetomo Hospital in 2013 were the population of control. The number of respondents in this study were 90 respondents were drawn from population using simple random sampling method. The variables studied were the use of hormonal contraceptives and age of menarche. The results of the analysis used binary logistic regression (α = 5% indicated that the use of hormonal contraceptives (p = 0,028; OR = 3,266 and age of menarche (p =0,031; OR = 3,492 has an significant correlation with incidence of breast cancer in women at Dr. Soetomo Hospital in 2013. It is expected that the community can be more accurate in determining the duration of hormonal contraception usage and avoid lifestyle can accelerate the occurrence of menarche.

    To study the secular trend of menarche in high-school urban adolescent girls (Zagreb, Croatia) over the last two decades, and to evaluate the possible impact of worsening of socio-economic conditions on age at menarche during the Croatian War of Independence (1991-1995). Three surveys of female adolescents aged 15-19 years: (a) 523 girls interviewed in 1990, (b) 888 girls interviewed in 1997, and (c) 399 girls interviewed in 2010. Self-reported age at menarche (in decimal years) was presented by age groups and year of interview. Differences in mean age at menarche between adolescent age groups as well as between surveys were tested using One-way ANOVA. The mean age at menarche was 12.82 years in 1990, 12.92 years in 1997 and 12.31 years in 2010. It increased by 0.10 years from 1990 to 1997 (p=0.290) and then declined by 0.61 years from 1997 to 2010 (pZagreb adolescents continued to decline significantly from 1990 to 2010 (p<0.001), in spite of a statistically insignificant initial increase between 1990 and 1997. When put in broader context, age at menarche mirrored socio-economic changes in the war period. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  16. Age at menarche and risk of colorectal cancer: a meta-analysis.

    Directory of Open Access Journals (Sweden)

    Chun-Yan Li

    Full Text Available BACKGROUND: Various observational studies have focused on the relationship between menarcheal age and the risk of colorectal cancer (CRC. However, the association is still controversial because of inconsistent results. Therefore, we performed a meta-analysis to assess this issue from epidemiological studies. METHODS: After a literature search in MEDLINE, EMBASE, and Web of Science for studies of menarcheal age and CRC risk published through the end of January 2013, we pooled the relative risks (RRs from included studies using a fixed- or random-effects model and performed heterogeneity and publication bias analyses. All statistical tests were two-sided. RESULTS: Eleven case-control and 11 cohort studies were eligible for inclusion in our analysis. The random-effects pooled RR for oldest versus youngest menarcheal age was 0.95 [95% confidence intervals (CIs = 0.85-1.06], with significant heterogeneity (Q = 61.03, P<0.001, I (2 = 65.6%. When separately analyzed, case-control (RR = 0.95, 95% CI = 0.75-1.21 and cohort studies (RR = 0.97, 95% CI = 0.90-1.04 yielded similar results. Moreover, similar results were also observed among the subgroup analyses by study quality, population, exposure assessment, anatomic cancer site, subsite of colon cancer, and several potential important confounders and risk factors. There was no evidence of publication bias and significant heterogeneity between subgroups detected by meta-regression analyses. CONCLUSIONS: Findings from this meta-analysis demonstrated that menarcheal age was not associated with the risk of CRC in humans. Further studies are warranted to stratify results by the subsite of colon cancer and menopause status in the future.

  19. Rural–urban variations in age at menarche, adult height, leg-length and abdominal adiposity in black South African women in transitioning South Africa

    Science.gov (United States)

    2018-01-01

    Abstract Background: The pre-pubertal socioeconomic environment may be an important determinant of age at menarche, adult height, body proportions and adiposity: traits closely linked to adolescent and adult health. Aims: This study explored differences in age at menarche, adult height, relative leg-length and waist circumference between rural and urban black South African young adult women, who are at different stages of the nutrition and epidemiologic transitions. Subjects and methods: We compared 18–23 year-old black South African women, 482 urban-dwelling from Soweto and 509 from the rural Mpumalanga province. Age at menarche, obstetric history and household socio-demographic and economic information were recorded using interview-administered questionnaires. Height, sitting-height, hip and waist circumference were measured using standardised techniques. Results: Urban and rural black South African women differed in their age at menarche (at ages 12.7 and 14.5 years, respectively). In urban women, a one-year increase in age at menarche was associated with a 0.65 cm and 0.16% increase in height and relative leg-length ratio, respectively. In both settings, earlier age at menarche and shorter relative leg-length were independently associated with an increase in waist circumference. Conclusions: In black South African women, the earlier onset of puberty, and consequently an earlier growth cessation process, may lead to central fat mass accumulation in adulthood. PMID:29557678

    Associations of breast cancer overall with indicators of exposures during puberty are reasonably well characterized; however, uncertainty remains regarding the associations of height, leg length, sitting height and menarcheal age with hormone receptor-defined malignancies. Within the European Prospective Investigation into Cancer and Nutrition cohort, Cox proportional hazards models were used to describe the relationships of adult height, leg length and sitting height and age at menarche with risk of estrogen and progesterone receptor negative (ER-PR-) (n = 990) and ER+PR+ (n = 3,524) breast tumors. Height as a single risk factor was compared to a model combining leg length and sitting height. The possible interactions of height, leg length and sitting height with menarche were also analyzed. Risk of both ER-PR- and ER+PR+ malignancies was positively associated with standing height, leg length and sitting height and inversely associated with increasing age at menarche. For ER+PR+ disease, sitting height (hazard ratios: 1.14[95% confidence interval: 1.08-1.20]) had a stronger risk association than leg length (1.05[1.00-1.11]). In comparison, for ER-PR- disease, no distinct differences were observed between leg length and sitting height. Women who were tall and had an early menarche (≤13 years) showed an almost twofold increase in risk of ER+PR+ tumors but no such increase in risk was observed for ER-PR- disease. Indicators of exposures during rapid growth periods were associated with risks of both HR-defined breast cancers. Exposures during childhood promoting faster development may establish risk associations for both HR-positive and -negative malignancies. The stronger associations of the components of height with ER+PR+ tumors among older women suggest possible hormonal links that could be specific for postmenopausal women. Copyright © 2012 UICC.

    The aim of this study was to determine the effect of psychosocial factors on the age at menarche of girls in Federation of Bosnia and Herzegovina (FBH). A cross-sectional study was conducted from September 2002 to May 2003 in all Cantons of the FBH. The random stratified sample included 19.803 girls aged 9.0 to 17.5 years. Data were collected using the status quo method. Probit analysis was used to estimate median age at menarche and 95% confidence intervals. The present study shows that menarche occurred significantly earlier (pfamilies (median: 12.99 years, 95% confidence interval: 12.93-13.05) than in girls who grew up in intact families (median: 13.04 years, 95% confidence interval: 13.01-13.07). Analyzing separately the impact of each of family stressors on age at menarche, we found that menarcheal age was significantly lower in girls from single-mother families, whose parents are divorced, whose one parent is died and where alcoholism in family is present than in girls from intact families. Maturation was found to be earlier in girls from dysfunctional families then in those from intact families after the influence of place of residence and sibship size was eliminated. From our research we can conclude that the girls from dysfunctional families reached earlier age at menarche than their peers who grew up in normal families, and that this effect did not disappear after controlling for socioeconomic variables.

    Full Text Available PURPOSE: Studies indicate that milk intake is associated with insulin-like growth factor 1 (IGF-1 concentrations and height in childhood, whether milk and other dairy products promote puberty remains unclear. This study aimed to investigate influences of pre-pubertal intakes of milk, yogurt and cheese on menarcheal age in Tehranian girls. The associations of total dietary calcium (Ca, magnesium (Mg, and phosphorus (P with menarcheal age were also examined. METHODS: This prospective study was conducted on 134 pre-pubertal girls, aged 4-12 years at baseline, who participated in the Tehran Lipid and Glucose Study (TLGS, and were followed for a median of 6.5 years. Dietary intakes were determined at initiation of the study using two non-consecutive 24-h dietary recalls and the age of menarche was documented during the follow-up. Logistic regression was used to calculate the risk of reaching menarche ≤ 12 years according to pre-pubertal levels of dairy or mineral intakes. RESULTS: The risk of earlier menarche was higher in girls with higher intakes of milk [OR: 2.28 (95% CI: 1.03-5.05], Ca [OR: 3.20 (95%CI: 1.39-7.42], Mg [OR: 2.43 (95% CI: 1.12-5.27] and P [OR: 3.37 (95 % CI: 1.44-7.87 after controlling for energy and protein intake, interval between the age at study initiation and the age of menarche, and maternal age at menarche (Model 1. Girls in the middle tertile of cheese intakes had a lower risk of reaching menarche ≤ 12 years than those in the lowest tertile after controlling for covariates in model 1. These associations remained significant after further adjustment of BMI Z-score at baseline. The relationship of Ca, Mg, and P with menarche remained after further adjustment for height Z-score at baseline, whereas the association between milk and cheese intakes became non-significant. CONCLUSIONS: Pre-pubertal intake of milk, but not cheese and yogurt, may hasten age at menarche.

    2015-08-01

    Manuck, Craig, Flory, Halder, and Ferrell (2011) reported that a theoretically anticipated effect of family rearing on girls' menarcheal age was genetically moderated by two single nucleotide polymorphisms (SNPs) of the estrogen receptor-α gene. We sought to replicate and extend these findings, studying 210 White females followed from birth. The replication was general because a different measure of the rearing environment was used in this inquiry (i.e., maternal sensitivity) than in the prior one (i.e., family cohesion). Extensions of the work included prospective rather than retrospective measurements of the rearing environment, reports of first menstruation within a year of its occurrence rather than decades later, accounting for some heritability of menarcheal age by controlling for maternal age of menarche, and using a new model-fitting approach to competitively compare diathesis-stress versus differential-susceptibility models of Gene × Environment interaction. The replication/extension effort proved successful in the case of both estrogen receptor-α SNPs, with the Gene × Environment interactions principally reflecting diathesis-stress: lower levels of maternal sensitivity predicted earlier age of menarche for girls homozygous for the minor alleles of either SNP but not for girls carrying other genotypes. Results are discussed in light of the new analytic methods adopted.

    Full Text Available A subset of results from the recently completed Jefferson Lab Qweak experiment are reported. This experiment, sensitive to physics beyond the Standard Model, exploits the small parity-violating asymmetry in elastic e→p$\\vec e{\\rm{p}}$ scattering to provide the first determination of the proton’s weak charge Qwp$Q_w^p$. The experiment employed a 180 μA longitudinally polarized 1.16 GeV electron beam on a 35 cm long liquid hydrogen target. Scattered electrons in the angular range 6° < θ < 12° corresponding to Q2 = 0.025 GeV2 were detected in eight Cerenkov detectors arrayed symmetrically around the beam axis. The goals of the experiment were to provide a measure of e→p$\\vec e{\\rm{p}}$ to 4.2% (combined statisstatistical and systematic error, which implies a measure of sin2(θw at the level of 0.3%, and to help constrain the vector weak quark charges C1u and C1d. The experimental method is described, with particular focus on the challenges associated with the world’s highest power LH2 target. The new constraints on C1u and C1d provided by the subset of the experiment’s data analyzed to date will also be shown, together with the extracted weak charge of the neutron.

    The first of its kind, GNSS-R complete orbital mission, CYGNSS was successfully launched on Dec 15 2016. The goal of this mission is to accurately forecast the intensification of tropical cyclones by modelling its inner core. The 8 micro observatories of CYGNSS carry a passive instrument called Delay Doppler Mapping Instrument (DDMI). The DDMIs form a 2D representation called the Delay-Doppler Map (DDM) of the forward scattered power signal. Each DDMI outputs 4 DDMs per second which are compressed and sent to the ground resulting in a total of 32 sea-surface measurements produced by the CYGNSS constellation per second. These are subsequently used in the Level-2 wind retrieval algorithm to extract wind speed information. In this paper, we perform calibration and validation of CYGNSS measurements for accurate extraction of wind speed information. The calibration stage involves identification and correction for dependence of the CYGNSS observables namely Normalised Bistatic Radar Cross Section and Leading Edge Slope of the Integrated Delay Waveform over instrument parameters, geometry etc. The validation stage involves training of the Geophysical Model Function over a multitude of ground truth sources during the Atlantic hurricane season and also refined validation of high wind speed data products.

    For 10 months the Infrared Astronomical Satellite (IRAS) provided astronomers with what might be termed their first view of the infrared sky on a clear, dark night. Without IRAS, atmospheric absorption and the thermal emission from both the atmosphere and Earthbound telescopes make the task of the infrared astronomer comparable to what an optical astronomer would face if required to work only on cloudy afternoons. IRAS observations are serving astronomers in the same manner as the photographic plates of the Palomar Observatory Sky Survey; just as the optical survey has been used by all astronomers for over three decades, as a source of quantitative information about the sky and as a roadmap for future observations, the results of IRAS will be studied for years to come. IRAS has demonstrated the power of infrared astronomy from space. Already, from a brief look at a miniscule fraction of the data available, we have learned much about the solar system, about nearby stars, about the Galaxy as a whole and about distant extragalactic systems. Comets are much dustier than previously thought. Solid particles, presumably the remnants of the star-formation process, orbit around Vega and other stars and may provide the raw material for planetary systems. Emission from cool interstellar material has been traced throughout the Galaxy all the way to the galactic poles. Both the clumpiness and breadth of the distribution of this material were previously unsuspected. The far-infrared sky away from the galactic plane has been found to be dominate by spiral galaxies, some of which emit more than 50% and as much as 98% of their energy in the infrared - an exciting and surprising revelation. The IRAS mission is clearly the pathfinder for future mission that, to a large extent, will be devoted to the discoveries revealed by IRAS. 8 figures

    This is a retrospective study based on growth and development data published in Venezuela by various authors in the period 1936-1978. The data on height for males of the middle and high socioeconomic strata show growth curves which are very similar to the standards for British children. Likewise, the girls of the same socioeconomic condition follow the British standards, but only up to about 10-12 years of age. After that age, the girls studied by the Venezuelan authors, show a pattern of early maturation with a corresponding lower adult height compared with their British counterparts. There were differences in the growth curves according to the socioeconomic strata. These differences were more marked in the girls data. A secular increase for height was discerned, from the published data, in all socioeconomic strata and in both sexes. The data on sexual maturation showed a tendency for progressively early menarche in Venezuelan girls. These changes in growth in height and age of menarche were more notorious and came about at an earlier age in the upper socioeconomic strata. They were less marked, not constant, and came about later in the lower socioeconomic groups. The secular changes in height and sexual maturation apparent from these data, could be explained by an improvement in the environmental conditions, especially nutrition and hygiene of the population, and also be genetic heterosis from European immigration and with improvement in communications.

    Menarche is a significant milestone for young women, representing an important juncture between girlhood and maturation. The limited literature that exists suggests that a mother's reaction to her daughter's first periods can shape her experiences and perceptions of menstruation which, in turn, may impact on her self-image and, consequently,…

    Menarcheal age is the age at which menstruation begins. Menarcheal age is regarded as a sensitive indicator of physical, biological and psychological environment. 1) To determine the menarcheal age and to examine the relationship between current age at menarche with anthropometric measures in Punjabi bania girls. 2) To develop maturity standards for Bania girls. The present cross-sectional survey was carried out on 200 bania girls at the age of onset of menarche. Menarcheal data was obtained by status quo method by asking about whether menarche has been experienced or not. In the present survey adolescent girls were interviewed with the help of pre-designed questionnaire. Statistical analysis was carried out in SPSS software, version 16.0. The data were analysed using descriptive statistics and one-way ANOVA. Pearson's correlation coefficient was used for correlation studies. A total of 200 Punjabi bania girls were examined in the study. The median age of onset of menarche in these girls was 12.3 years. Menarcheal age was positively associated with bi-acromial width, bi-iliac width and arm span. The present research has revealed secular trend in the age of onset of menarche as indicated by median age of 12.3 years in Bania girls. The bi-acromial width, bi-iliac width and arm span were also correlated with the age of menarche.

    Declining age at menarche has been observed in many countries. In China, a decrease of 4.5 months per decade in the average age at menarche among the majority Han girls has recently been reported. However, the trends in age at menarche among ethnic minority girls over the past 25 years remain unknown. To compare the differences in median age at menarche among girls aged 9-18 years across 24 ethnic minorities in 2010 and to estimate the trends in age at menarche in different ethnic minorities from 1985 to 2010. We used data from six cross-sectional Chinese National Surveys on Students' Constitution and Health (1985, 1991, 1995, 2000, 2005, and 2010). The median age at menarche was estimated by using probit analysis. In 2010, the ethnic minorities with the earliest age at menarche were the Koreans (11.79 years), Mongolians (12.44 years), and Zhuang (12.52 years). The three ethnic minorities with the latest age at menarche were the Sala (14.32 years), Yi (13.74 years), and Uighurs (13.67 years). From 1985 to 2010, the age at menarche declined in all 24 minority groups. The Lisu, Kazakh, and Korean minorities showed the largest reductions in age at menarche by 1.79 (pminorities showed the smallest reductions, with age at menarche declining by only 0.06 (p>0.05), 0.15 (p>0.05), and 0.15 (p>0.05) years, respectively, in the same period. A large variation in age at menarche was observed among different ethnic minorities, with the earliest age at menarche found among Korean girls. A reduction in the average age at menarche appeared among most of the ethnic minorities over time, and the largest decrease was observed in Lisu, Kazakh, and Korean girls. Thus, health education should focus on targeting the specific needs of each ethnic minority group.

    Early retirement is predominantly considered as the result of incentives set by social security and the tax system. But people seem to retire early even in the absence of such distortions as the Swiss example demonstrates. We look for determinants of early retirement, in particular the role of lifetime income and family status, using individual data from a selection of Swiss pension funds. Our findings suggest that affordability is a key determinant in retirement decisions: More affluent men,...

    ABSTRACT Puberty is an important developmental stage wherein hormonal shifts mediate the physical and physiological changes that lead to menarche, but until now, the bacterial composition of vaginal microbiota during this period has been poorly characterized. We performed a prospective longitudinal study of perimenarcheal girls to gain insight into the timing and sequence of changes that occur in the vaginal and vulvar microbiota during puberty. The study enrolled 31 healthy, premenarcheal girls between the ages of 10 and 12 years and collected vaginal and vulvar swabs quarterly for up to 3 years. Bacterial composition was characterized by Roche 454 pyrosequencing and classification of regions V1 to V3 of 16S rRNA genes. Contrary to expectations, lactic acid bacteria, primarily Lactobacillus spp., were dominant in the microbiota of most girls well before the onset of menarche in the early to middle stages of puberty. Gardnerella vaginalis was detected at appreciable levels in approximately one-third of subjects, a notable finding considering that this organism is commonly associated with bacterial vaginosis in adults. Vulvar microbiota closely resembled vaginal microbiota but often exhibited additional taxa typically associated with skin microbiota. Our findings suggest that the vaginal microbiota of girls begin to resemble those of adults well before the onset of menarche. PMID:25805726

  17. The influence of strenuous muscle stimulation on the menarche.

    Nowadays, the average age at which menarche begins is lowering by three to four years every century, that is, four months every decade, according to both Japanese, and European and American annual changes of the average age. It emerged that the menarche shows a tendency to occur later in female gymnasts, because of the influence of strenuous muscle stimulation, and the fact that a higher level of technic is required in gymnastic games each year. These conclusions have been drawn from replies submitted to a questionnaire distributed among a relatively small number of gymnasts who participated in the competitions including the Inter High School Championship and the World Cup Championship. For example, at the age of 14, the percentage of women who had menstruated is almost 100% among women in general, but only 24% among World Cup Championship gymnasts, the average age at menarche of the latter being later than that of the former by as many as 3 years. At the age of 16, the percentage of women who had menstruated is 100% among women in general, but on the other hand, it is only 60% among World Cup Championship gymnasts, in other words, only a low percentage of women, of the latter group, had menstruated. Finally in our study, we established that the age at menarche of gymnasts is three or five years later than that of women in general. From our study, we concluded that the excessive burden imposed on muscles might cause an abnormal menstrual cycle, and the influence on menstruation would be considerable.

Vulvar microbiota closely resembled vaginal microbiota but often exhibited additional taxa typically associated with skin microbiota. Our findings suggest that the vaginal microbiota of girls begin to resemble those of adults well before the onset of menarche. This study addresses longitudinal changes in vaginal and vulvar microbial communities prior to and immediately following menarche. The research is significant because microbial ecology of the vagina is an integral aspect of health, including resistance to infections. The physiologic changes of puberty and initiation of cyclic menstruation are likely to have profound effects on vaginal microbiota, but almost nothing is known about changes that normally occur during this time. Our understanding has been especially hampered by the lack of thorough characterization of microbial communities using techniques

    Full Text Available Introduction: Adolescence marks the onset of female puberty. The first menstruation is often horrifying and traumatic to an adolescent girl because it usually occurs without her knowing about it. Implications of a girl′s response to menarche have a socio-cultural and religious significance. Aim and Objective: To study the sociocultural and physiological implications of menstruation in college going girls. Materials and Methods: This was a community-based cross-sectional observational study undertaken among college girls. All the girls (n = 252 of the college were enrolled in the study. A structured questionnaire was used as the study tool. The questionnaire included topics related to sociodemographic information, sociocultural implications and first informant about the physiological process of menstruation along with its timing. Results: Majority of the study subjects (77.40% observed restrictions for religious/holy things. Sleep disturbances were the most common (59% disturbance faced by the study subjects. Of a total of 252 respondents, majority [104 (41.30%] had leg cramps. The first informant of menstruation was the mother in 196 (77.78% girls. Of 252 girls, 86 (34.12% had pre-menarcheal knowledge of menstruation. Mothers from the urban area and with better education tend to give knowledge of menstruation prior to menarche of her daughter. An increasing trend was observed with increasing educational status of the mother and proportion of them giving pre-menarcheal knowledge of menstruation to their daughter. Conclusions: Menstruation is associated with a high burden of sociocultural implications. Pre-menarcheal knowledge of menstruation is poor. Mothers from the urban area and with better educational level tend to give knowledge of menstruation prior to menarche of their daughter.

    Early pubertal timing is known to put women at greater risk for adverse physiological and psychological health outcomes. Of the factors that influence girls' pubertal timing, stress experienced during childhood has been found to advance age at menarche (AAM). However, it is not known if stress experienced by mothers during or in the months before conception can be similarly associated with earlier pubertal timing. Prenatal maternal stress (PNMS) is associated with metabolic changes, such as increased childhood adiposity and risk of obesity, that have been associated with earlier menarchal age. Using a prospective longitudinal design, the present study tested whether PNMS induced by a natural disaster is either directly associated with earlier AAM, or whether there is an indirect association mediated through increased girls' body mass index (BMI) during childhood. A total of 31 girls, whose mothers were exposed to the Quebec's January 1998 ice storm during pregnancy were followed from 6 months to 5 1/2 to 5.5 years of age. Mother's stress was measured within 6 months of the storm. BMI was measured at 5.5 years, and AAM was assessed through teen's self-report at 13.5 and 15.5 years of age. Results revealed that greater BMI at 5.5 years mediated the effect of PNMS on decreasing AAM [B=-0.059, 95% confidence intervals (-0.18, -0.0035)]. The present study is the first to demonstrate that maternal experience of stressful conditions during pregnancy reduces AAM in the offspring through its effects on childhood BMI. Future research should consider the impact of AAM on other measures of reproductive ability.

    Full Text Available Background: Menarche and skeletal maturation indices are physiological maturation indicators that can be used to establish the maturation stage of individual patient in orthodontic treatment, especially in orthodontic growth modification and orthognatic surgery. Purpose: The purpose of this study was to determine the relationship between menarche and the peak of skeletal maturation using hand-wrist and cervical vertebrae indexes. Methods: This was an observational diagnostic research with 220 female of Deutero-Malay Indonesian subjects aged 8-17 years from Dental Hospital Faculty of Dentistry Universitas Padjadjaran, and some privates orthodontic practice in Bandung. All subjects had hand-wrist radiograph and lateral cephalogram. Menarche data were collected through interview with the subjects and their parents. There were 89 subjects who already had menarche but only 84 of them remembered the month and year of their menarche. The stage of hand-wrist skeletal maturation was analyzed using Fishman method and cervical vertebrae maturation was analyzed using Baccetty et.al., method. Results: The result indicates that the menarche age of Indonesian DeuteroMalay subject were 12.47 ± 0.73 year. The youngest age of were 10.92 ± 0.0 year and the oldest were 13.83 ± 0.23 year. Conclusion: Menarche could be used as an indicator that the pubertal growth peak has been exceeded and to predict the end of the pubertal growth. This study showed that 0.49 years after MP3cap stage of hand-wrist skeletal maturation index and 0.69 years after CVMS2 stage of cervical vertebrae skeletal maturation index, the subject of Indonesian Deutero-Malay will have their menarche.

    2004-12-01

    The purpose of this study was to assess the well-being and health status of Chinese immigrant women in Italy. The subjects (mean 29.5 years) frequented the "Health Center for Foreign Women and their Children" in Bologna, Italy. Information on living conditions, biological characteristics and pregnancy or maternity was obtained through interviews of the women in the Center during normal medical visits. Data on menarche age were based on the retrospective method since all the women were in China at the onset of menarche. Social factors influencing the health and behavior of Chinese women in Italian society are discussed. The analysis on children sex ratio at birth indicates that the old cultural Chinese tradition of son preference still continues to exist. These women have achieved a socio-economic improvement and generally good health status in Italy. The difficult living conditions they faced in China are indirectly reflected in their delayed puberty (14.4 +/- 1.4 years). The delayed sexual development was probably due to the same situation of severe poverty that forced them to migrate.

    To analyze various parameters affect local control, we reviewed the results of radiotherapy for early glottic carcinoma. Between 1977 and 1997, 64 patients with untreated early glottic carcinoma and four patients with recurrent early glottic carcinoma were analyzed retrospectively. All tumors were classified as follows; T1 (n=56), T2 (n=12); well differentiated (n=33), moderately (n=25), poorly (n=1), unknown (n=9); very small tumor (VST) (n=46), small tumor (ST) (n=22). All patients were treated utilizing a cobalt-60 unit to a total dose that ranged from 56 Gy to 64 Gy (mean 60 Gy). The mean treatment time was 44 days (range 38-49). The local control rates at 2 years and 5 years for all patients were 85% and 78%, respectively. On univariate analysis, tumor size (p=0.0146) and recurrent or untreated tumor (p=0.0226) affected local control. On multivariate analysis, tumor size (p=0.0273) and recurrent or untreated tumor (p=0.0495) were also significant factors that affected local control. (author)

    This study was performed to evaluate the cosmetic outcome of conservative treatment for early breast cancer and to analyze the factors influencing cosmetic outcome. From February 1992 through January 1997, 120 patients with early breast cancer were treated with conservative surgery and postoperative radiotherapy. The types of conservative surgery were quadrantectomy and axillary node dissection for 108 patients (90%) and lumpectomy or excisional biopsy for 10 patients (8.3%). Forty six patients (38%) received adjuvant chemotherapy (CMF or CAF). Cosmetic result evaluation was carried out between 16 and 74 months (median, 33 months) after surgery. The cosmetic results were classified into four categories, i.e., excellent, good, fair, and poor. The appearances of the patients' breasts were also analyzed for symmetry using the differences in distances from the stemal notch to right and left nipples. A logistic regression analysis was performed to identify independent variables influencing the cosmetic outcome. Cosmetic score was excellent or good in 76% (91/120), fair in 19% (23/120) and poor in 5% (6/ 120) of the patients. Univariate analysis showed that tumor size (T1 versus T2) (p=0.04), axillary node status (NO versus N1) (p=0.0002), extent of surgery (quadrantectomy versus lumpectomy or excisional biopsy) (p=0.02), axillary node irradiation (p=0.0005) and chemotherapy (p=0,0001) affected cosmetic score. Multivariate analysis revealed that extent of surgery (p=0.04) and chemotherapy (p=0.0002) were significant factors. For breast symmetry, univariate analysis confirmed exactly the same factors as above. Multivariate analysis revealed that tumor size (p=0.003) and lymph node status (p=0.007) affected breast symmetry. Conservative surgery and postoperative radiotherapy resulted in excellent or good cosmetic outcome in a large portion of the patients. Better cosmetic results were achieved generally in the group of patients with smaller tumor size, without axillary

    The Whisper instrument yields two data sets: (i) the electron density determined via the relaxation sounder, and (ii) the spectrum of natural plasma emissions in the frequency band 2-80 kHz. Both data sets allow for the three-dimensional exploration of the magnetosphere by the Cluster mission...... the drift velocity of density structures. Wave observations are also of crucial interest for studying small-scale structures, as demonstrated in an example in the fore-shock region. Early results from the Whisper instrument are very encouraging, and demonstrate that the four-point Cluster measurements...... largely overcomes the limited telemetry allocation. The natural emissions are usually related to the plasma frequency, as identified by the sounder, and the combination of an active sounding operation and a passive survey operation provides a time resolution for the total density determination of 2.2 s...

    Experiences and constructions of menarche and menstruation are shaped by the sociocultural environment in which women are embedded. We explored experiences and constructions of menarche and menstruation among migrant and refugee women resettled in Sydney, Australia, and Vancouver, Canada. Seventy-eight semistructured individual interviews and 15 focus groups comprised of 82 participants were undertaken with women from Afghanistan, Iraq, Somalia, South Sudan, Sudan, Sri Lanka, and varying South American countries. We analyzed the data using thematic decomposition, identifying the overall theme "cycles of shame" and two core themes. In "becoming a woman," participants constructed menarche as a marker of womanhood, closely linked to marriage and childbearing. In "the unspeakable," women conveyed negative constructions of menstruation, positioning it as shameful, something to be concealed, and polluting. Identifying migrant and refugee women's experiences and constructions of menarche and menstruation is essential for culturally safe medical practice, health promotion, and health education.

    First, to explore the kind of information that Mexican mothers give their daughters about menstruation before their menarche, and to study the impact of this communication on how prepared the daughters felt when they experienced their menarche. Second, to investigate the influence of the menarcheal experience on attitudes toward menstruation. Cross-sectional survey. Sample of adolescents attending 3 different public schools. 405 Mexican postmenarcheal adolescents, aged 12-15 years. Participants answered a questionnaire that had 3 parts: (a) General data, (b) topics related to menses that participants had discussed with their mothers prior to menarche, and (c) menarcheal experience. They also answered a questionnaire about menstrual attitudes. Although most of the participants knew what they should do when they experienced their menarche, only 39% stated they had felt prepared to start menstruating. Regarding menstrual attitudes, adolescents scored highest on Negative Feelings and Secrecy rather than on Positive Feelings. Participants who had previously discussed the emotional aspects of menses with their mothers were more likely to claim they had felt prepared to start menstruating when they got their first period (OR = 3.45). The fact that adolescents felt prepared to start menstruating predicted positive attitudes toward menstruation (β = .19) Discussing the emotional aspects of menses prior to menarche is crucial to being prepared for menarche, and to holding positive attitudes toward menstruation. Information on biological knowledge and practical aspects of menses needs to be supplemented with emotional issues. Copyright © 2012 North American Society for Pediatric and Adolescent Gynecology.

  19. Secular trends in menarcheal age in India-evidence from the Indian human development survey.

    Directory of Open Access Journals (Sweden)

    Praveen Kumar Pathak

    Full Text Available Evidence from a number of countries in Europe and North America point towards the secular declining trend in menarcheal age with considerable spatial variations over the past two centuries. Similar trends were reported in several developing countries from Asia, Africa and Latin America. However, data corroborating any secular trend in the menarcheal age of the Indian population remained sparse and inadequately verified.We examined secular trends, regional heterogeneity and association of socioeconomic, anthropometric and contextual factors with menarcheal age among ever-married women (15-49 years in India. Using the pseudo cohort data approach, we fit multiple linear regression models to estimate secular trends in menarcheal age of 91394 ever-married women using the Indian Human Development Survey.The mean age at menarche among Indian women was 13.76 years (95 % CI: 13.75, 13.77 in 2005. It declined by three months from 13.83 years (95% CI: 13.81, 13.85 among women born prior to 1955-1964, to nearly 13.62 years (95% CI: 13.58, 13.67 among women born during late 1985-1989. However, these aggregate national figures mask extensive spatial heterogeneity as mean age at menarche varied from 15.0 years in Himachal Pradesh during 1955-1964 (95% CI: 14.89-15.11 to about 12.1 years in Assam (95% CI: 11.63-12.56 during 1985-1989.The regression analysis established a reduction of nearly one month per decade, suggesting a secular decline in age at menarche among Indian women. Notably, the menarcheal age was significantly associated with the area of residence, geographic region, linguistic groups, educational attainment, wealth status, caste and religious affiliations among Indian women.

    The aim of this study was to qualitatively record the cultural attitudes and practices associated with menarche and menstruation in Taiwanese girls, particularly with respect to coping mechanisms. Forty-eight adolescent girls participated. Adolescent girls were individually interviewed to investigate the effects of their cultural practices, coping mechanisms, and physiological symptoms during menarche and menstruation. The qualitative investigation revealed mixed reactions to menstruation, such as eating chocolate, using sanitary napkins, and feeling irritable or embarrassed. Cluster construction suggested that adolescents were prepared for menarche but required emotional support; in addition, the new generation employed the Internet to learn how to cope. A phenomenological approach showed that menarche and menstrual attitudes among Taiwanese adolescents were comprised in 4 dimensions: self-perception, information, and cultural practices with regard to menarche; physiological symptoms and psychological reactions during menstruation; coping mechanisms during menarche and menstruation; and methods for coping and cultural practices for menstruation. Cultural beliefs and the Internet have changed cross-cultural contacts. Educators and health professionals should seek to understand this generation of girls, who perceive the world as more flexible and available and have more creativity and new eating behaviors and hobbies.

    Menarche signifies the primary event in female puberty and is associated with changes in self-identity. It is not clear whether earlier puberty causes girls to spend less time in education. Observational studies on this topic are likely to be affected by confounding environmental factors. The Mendelian randomization (MR) approach addresses these issues by using genetic variants (such as single nucleotide polymorphisms, SNPs) as proxies for the risk factor of interest. We use this technique to explore whether there is a causal effect of age at menarche on time spent in education. Instruments and SNP-age at menarche estimates are identified from a Genome Wide Association Study (GWAS) meta-analysis of 182,416 women of European descent. The effects of instruments on time spent in education are estimated using a GWAS meta-analysis of 118,443 women performed by the Social Science Genetic Association Consortium (SSGAC). In our main analysis, we demonstrate a small but statistically significant causal effect of age at menarche on time spent in education: a 1 year increase in age at menarche is associated with 0.14 years (53 days) increase in time spent in education (95% CI 0.10-0.21 years, p = 3.5 × 10 -8 ). The causal effect is confirmed in sensitivity analyses. In identifying this positive causal effect of age at menarche on time spent in education, we offer further insight into the social effects of puberty in girls.

    The purpose of the present paper was to review the results of treating early stages glottic, squamous cell carcinoma by radiotherapy in the Department of Radiation Oncology, Prince of Wales Hospital, Sydney. A retrospective review was carried out of all patients seen in the department from 1967 to 1994, inclusive. To be eligible, patients had to have newly diagnosed cancer and to have been treated with curative intent by radiotherapy alone. Three hundred and sixty-nine patients satisfied the eligibility requirements. The mean follow-up time was 12.2 years (maximum: 28 years). At 5 years the actuarial local control rate was 80% (84% for stage T 1 and 72% for T 2 ). The ultimate local control rate was 96%. The overall survival rates at 5 and 10 years were 73% and 52%, respectively. The risk of nodal recurrence was much higher after persisting disease or local recurrence. Our results confirm the high cure rates achieved with this modality of treatment and are comparable with those reported in the literature. Copyright (1999) Blackwell Science Pty. Ltd

    The purpose of this study is to investigate the esophagographic findings of early esophageal cancer (EEC), and to compare these with the pathologic results, and to thus determine the most useful method of esophagography for detection of EEC. We examined 18 patients (M:F=16:2) with pathologically proven EEC; 17 cases were squamous cell carcinoma and one was adenocarcinoma. Tumor size, shape and location were evaluated by esophagography and the findings were compared with the pathologic results. The tumors were 0.5 - 7 cm in size; all except two were smaller than 4 cm. Twelve were located in the middle esophagus, five cases in the lower esophagus and one case in the upper esophagus; in ten cases, the margin was ill-defined. Esophagography showed that eight cases were of the superficial depressed type, seven were the superficial elevated type, and three were the tumorous type. All 18 cases were detected by double contrast study, but mucosal relief study and barium filling study revealed only ten and eight cases, respectively; for the detection of EEC double contrast study was thus the most useful. EEC was commonly demonstrated in the middle esophagus with an ill-defined margin; it was of the superficial depressed or elevated type. For the detection of EEC, double contrast study was the most useful. (author). 14 refs., 1 tab., 5 figs

    Full Text Available Aim: The goal in anterior cruciate ligament reconstruction (ACLR is to restore the normal anatomic structure and function of the knee. In the significant proportion of patients after the traditional single-bundle ACLR, complaints of instability still continue. Anatomic double bundle ACLR may provide normal kinematics in knees, much closer to the natural anatomy. The aim of this study is to clinically assess the early outcomes of our anatomical double bundle ACLR. Material and Method: In our clinic between June 2009 and March 2010, performed the anatomic double bundle ACLR with autogenous hamstring grafts 20 patients were evaluated prospectively with Cincinnati, IKDC and Lysholm scores and in clinically for muscle strength and with Cybex II dynamometer.

    Menarche is a significant physical and emotional experience for adolescent girls, especially in certain cultures, where it is viewed as a rite of passage, affecting the meaning of lived experiences. The purpose of the study was to explore the menarche experience among Jordanian adolescent girls when they reach menarche. Interpretive phenomenological analysis. Az-Zarqa City, Jordan. A homogenous sample of 7 Jordanian girls, ages 12-14 years, who had their first menstruation within the past 6 months. Participants were asked to narrate their experiences through journal writing; their reports to be used for interpretive phenomenological analyses by 2 independent researchers, to ensure the findings' trustworthiness. Three major themes emerged as: (1) menstruation as a forbidden topic; (2) keeping the "topic" to oneself; and (3) no more secrets. Each theme was characterized according to distinct sets of emotions and knowledge-seeking patterns because Jordanian culture and Islamic teachings had greatly influenced the girls' experience of menarche. Menarche was considered a social taboo; not to be openly discussed. At the first signs of menarche, participants were shocked, scared, confused, and anxious. They had limited information and support from their family or school system. Therefore, they relied on self-perceptions about menarche, and viewed the experience of menstruation with profound negative emotions. Participants hesitated to share their experiences with their mothers and close friends. They felt alone and experienced their emotional turmoil in isolation and without support. Jordanian adolescent girls need formal health education to understand and manage the reproductive changes that occur in their bodies.

    Early restored patency of the papilla has been hypothesized to reduce complications and mortality of acute biliary pancreatitis. The aim of this study was to evaluate the role of urgent laparoscopic cholecystectomy with intraoperative cholangiography and rendezvous when necessary in acute biliary pancreatitis natural history. Patients observed in the early stage of an acute biliary pancreatitis were included in the study. Operative risk assessment based on American Society of Anesthesiologists (ASA) score allowed the performance of urgent laparoscopic cholecystectomy within 72 h from onset of symptoms in 55 patients and a delayed intervention during the same admission in 21 patients. Intraoperative cholangiography was performed in all cases, and clearance of common bile duct was performed by flushing when possible, or rendezvous when necessary. Evolution of pancreatitis was evaluated with clinical and radiological monitoring. Urgent laparoscopic cholecystectomy was performed in all cases without conversion. At intraoperative cholangiography common bile duct was free in 25 patients, a papillary spasm was observed in 9, and common bile duct stones in 21 patients. Patency of the papilla was restored by flushing in 13 patients, while a rendezvous was necessary in 17 patients. The rate of organ failure and pancreatic necrosis was 1.8%, overall mortality was 1.8%, and overall morbidity 21.8%. No infectious complications of peripancreatic collections were observed. Urgent laparoscopic cholecystectomy with selective intraoperative rendezvous may be considered as a treatment option in the early stage of acute biliary pancreatitis.

    SnowEx is a multi-year airborne snow campaign with the primary goal of addressing the question: How much water is stored in Earth's terrestrial snow-covered regions? Year 1 (2016-17) focuses on the distribution of snow-water equivalent (SWE) and the snow energy balance in a forested environment. The year 1 primary site is Grand Mesa and the secondary site is the Senator Beck Basin, both in western, Colorado, USA. Ten core sensors on four core aircraft will make observations using a broad suite of airborne sensors including active and passive microwave, and active and passive optical/infrared sensing techniques to determine the sensitivity and accuracy of these potential satellite remote sensing techniques, along with models, to measure snow under a range of forest conditions. SnowEx also includes an extensive range of ground truth measurements—in-situ samples, snow pits, ground based remote sensing measurements, and sophisticated new techniques. A detailed description of the data collected will be given and some early results will be presented. Seasonal snow cover is the largest single component of the cryosphere in areal extent (covering an average of 46M km2 of Earth's surface (31 % of land areas) each year). This seasonal snow has major societal impacts in the areas of water resources, natural hazards (floods and droughts), water security, and weather and climate. The only practical way to estimate the quantity of snow on a consistent global basis is through satellites. Yet, current space-based techniques underestimate storage of snow water equivalent (SWE) by as much as 50%, and model-based estimates can differ greatly vs. estimates based on remotely-sensed observations. At peak coverage, as much as half of snow-covered terrestrial areas involve forested areas, so quantifying the challenge represented by forests is important to plan any future snow mission. Single-sensor approaches may work for certain snow types and certain conditions, but not for others

    Full Text Available The objective was to analyze the relationship between socioeconomic status and age at menarche among indigenous and non-indigenous girls in the Araucanía Region of Chile, controlling for nutritional status and mother's age at menarche. A total of 8,624 randomly selected girls from 168 schools were screened, resulting in the selection of 207 indigenous and 200 non-indigenous girls who had recently experienced menarche. Age at menarche was 149.6±10.7 months in the indigenous group and 146.6±10.8 months in the non-indigenous group. Among the non-indigenous, the analysis showed no significant association between age at menarche and socioeconomic status. In the indigenous group, age at menarche among girls with low socioeconomic status was 5.4 months later than among those with higher socioeconomic status. There were no differences in nutritional status according to socioeconomic level. Obesity was associated with earlier menarche. Menarche occurred earlier than in previous generations. An inverse relationship between socioeconomic status and age at menarche was seen in the indigenous group only; low socioeconomic status was associated with delayed menarche, regardless of nutritional status or mother's age at menarche.El objetivo fue analizar la relación entre nivel socioeconómico y edad de menarquia en adolescentes indígenas y no indígenas de la Región de la Araucanía, Chile, controlando el efecto del estado nutricional, y la edad de menarquia de las madres.

    1975-01-01

    The multifrequency satellite radio beacon enables the measurement of the columnar electron content of the ionosphere and plasmasphere along the ray path and its spatial and temporal structure. Measurements include modulation phase, Faraday rotation, and amplitude. The characteristics of the beacon transmitter and its design are presented together with the design of the Boulder receiver and antennas and the calibration procedures. A shape factor F is defined which depends on the electron density and geomagnetic field distributions. It is found that F varies by about 30 percent from day to night. It is shown that the ratio of the plasmaspheric content to total content varies from about 0.08 during the day to about 0.35 at night. Other examples which are presented to illustrate the uses of the radio beacon include sunrise effects, solar flare enhancements of total content, and the ionospheric storms of early July 1974

    To investigate the role of estrogen deprivation and replacement in amenorrheic and nonamenorrheic dancers on hormone therapy and calcium. Clinical, placebo-controlled, randomized trial study.Healthy volunteers in an academic research environment. Fifty-five dancers (mean age: 22.0 +/- 4.6, age at menarche: 14.7 +/- 2.3 years), including 24 amenorrheics. Amenorrheics were randomized in a controlled trial to receive placebo or Premarin, 0.625 mg for 25 days monthly, with Provera, 10 mg, for 10 of these 25 days (hormone therapy) for 2 years. These women were compared to normally menstruating controls. The study participants also received 1250 mg of calcium per day. Bone mineral density (BMD) measured at the foot, wrist, and lumbar spine. Our overall results showed no difference in BMD between the treated or placebo groups, indicating that hormone therapy did not change or normalize BMD when compared to normals. Five patients (all on placebo) who resumed menses during the study showed an increase in BMD without normalization. These findings suggest that mechanisms other than hypoestrogenism may be involved with the osteopenia associated with exercise-induced amenorrhea.

    Japan Meteorological Agency(JMA) started to provide Earthquake Early Warning(EEW) to the general public in October 2007. It was followed by provision of EEW to a limited number of users who understand the technical limit of EEW and can utilize it for automatic control from August 2006. Earthquake Early Warning in Japan definitely means information of estimated amplitude and arrival time of a strong ground motion after fault rupture occurred. In other words, the EEW provided by JMA is defined as a forecast of a strong ground motion before the strong motion arrival. EEW of JMA is to enable advance countermeasures to disasters caused by strong ground motions with providing a warning message of anticipating strong ground motion before the S wave arrival. However, due to its very short available time period, there should need some measures and ideas to provide rapidly EEW and utilize it properly. - EEW is issued to general public when the maximum seismic intensity 5 lower (JMA scale) or greater is expected. - EEW message contains origin time, epicentral region name, and names of areas (unit is about 1/3 to 1/4 of one prefecture) where seismic intensity 4 or greater is expected. Expected arrival time is not included because it differs substantially even in one unit area. - EEW is to be broadcast through the broadcasting media(TV, radio and City Administrative Disaster Management Radio), and is delivered to cellular phones through cell broadcast system. For those who would like to know the more precise estimation and smaller earthquake information at their point of their properties, JMA allows designated private companies to provide forecast of strong ground motion, in which the estimation of a seismic intensity as well as arrival time of S-wave are contained, at arbitrary places under the JMA’s technical assurance. From October, 2007 to August, 2009, JMA issued 11 warnings to general public expecting seismic intensity “5 lower” or greater, including M=7.2 inland

    We describe our first cut of data reduction on a wide variety of observations of the solar corona and of the effect of the penumbra and umbra on the terrestrial atmosphere, carried out from our eclipse site on the campus of Willamette University in Salem, Oregon. Our team of faculty, undergraduate students, graduate students, and other colleagues observed the eclipse, taking images and spectra with a variety of sensors and telescopes. Equipment included frame-transfer cameras observing at 3 Hz in 0.3 nm filters at the coronal green and red lines to measure the power spectrum of oscillations in coronal loops or elsewhere in the lower corona; 3 spectrographs; a variety of telescopes and telephotos for white-light imaging; a double Lyot system tuned at Fe XIV 530.3 nm (FWHM 0.4 nm) and Fe X 637.4 nm (FWHM 0.5 nm); and a weather station to record changes in the terrestrial atmosphere. We are comparing our observations with predictions based on the previous mapping of the photospheric magnetic field, and preparing wide-field complete coronal imaging incorporating NOAA/NASA GOES-16 SUVI and NRL/NASA/LASCO for the corona outside our own images (which extend, given the completely clear skies we had, at least 4 solar radii), and NASA SDO/AIA and NOAA/NASA GOES-16 SUVI for the solar disk. One of our early composites appeared as Astronomy Picture of the Day for September 27: https://apod.nasa.gov/apod/ap170927.htmlOur expedition was supported in large part by grants from the Committee for Research and Exploration of the National Geographic Society and from the Solar Terrestrial Program of the Atmospheric and Geospace Sciences Division of the National Science Foundation, with additional student support from the STP/AGS of NSF, the NASA Massachusetts Space Grant Consortium, the Sigma Xi honorary scientific society, the Clare Booth Luce Foundation studentship and the Freeman Foote Expeditionary Fund at Williams College, other Williams College funds, and U.

    1988-01-01

    The preliminary results of the USNRC/INEL high-energy BWR line break flow interruption testing are presented. Two representative nuclear valve assemblies were cycled under design basis Reactor Water Cleanup pipe break conditions to provide input for the technical basis for resolving the Nuclear Regulatory Commission's Generic Issue 87. The effects of the blowdown hydraulic loadings on valve operability, especially valve closure stem forces, were studied. The blowdown tests showed that, given enough thrust, typical gate valves will close against the high flow resulting from a line break. The tests also showed that proper operator sizing depends on the correct identification of values for the sizing equation. Evidence exists that values used in the past may not be conservative for all valve applications. The tests showed that improper operator lock ring installation following test or maintenance can invalidate in-situ test results and prevent the valve from performing its design function. 2 refs., 12 figs., 2 tabs

  3. External-environmental and internal-health early life predictors of adolescent development.

    A wealth of evidence documents associations between various aspects of the rearing environment and later development. Two evolutionary-inspired models advance explanations for why and how such early experiences shape later functioning: (a) the external-prediction model, which highlights the role of the early environment (e.g., parenting) in regulating children's development, and (b) the internal-prediction model, which emphasizes internal state (i.e., health) as the critical regulator. Thus, by using data from the NICHD Study of Early Child Care and Youth Development, the current project draws from both models by investigating whether the effect of the early environment on later adolescent functioning is subject to an indirect effect by internal-health variables. Results showed a significant indirect effect of internal health on the relation between the early environment and adolescent behavior. Specifically, early environmental adversity during the first 5 years of life predicted lower quality health during childhood, which then led to problematic adolescent functioning and earlier age of menarche for girls. In addition, for girls, early adversity predicted lower quality health that forecasted earlier age of menarche leading to increased adolescent risk taking. The discussion highlights the importance of integrating both internal and external models to further understand the developmental processes that effect adolescent behavior.

    To investigate the relationship of osteopenia and osteoporosis in apparently healthy postmenopausal patients with age at menarche, age at menopause and duration of fertility. One hundred and twenty-four apparently healthy Greek postmenopausal women underwent spinal and hip X-ray absorptiometry scans. Among them, 47 were classified as normal (control group), 52 as osteopenic, and 25 as having osteoporosis. These groups were compared according to their age at menarche (three subgroups of 10-12, 13 and 14-16 years old), at menopause (three subgroups of 40-45, 46-50 and > or = 51 years old) and duration of fertility (four subgroups of 40 and 41-45 years). The groups were not found to differ statistically according to age and age at menarche. However, decreased bone mineral density was found in patients with duration of fertility not exceeding 30 years (p = 0.034) and age at menopause less than 45 years (p = 0.034). No association was found between bone mineral density in Greek postmenopausal women and either number of live births or lactation. In postmenopausal females, the cumulative exposure to endogenous estrogens, measured as years of menstruation, seems to be a significant protective factor against the development of postmenopausal osteoporosis. Age at menopause between 40 and 45 years, but not age at menarche, correlated with low bone mineral density in postmenopausal females.

    The NASA Gravity Probe B orbiting gyroscope test of General Relativity, launched from Vandenberg Air Force Base on 20 April, 2004 tests two consequences of Einstein's theory: 1) the predicted 6.6 arcs/yr geodetic effect due to the motion of the gyroscope through the curved space-time around the Earth; 2) the predicted 0.039 arcs/yr frame-dragging effect due to the rotating Earth. The mission required the development of many technologies that did not exist when experiment was conceived in 1960. Cryogenic gyroscopes with drift-rates 7 orders of magnitude better than the best inertial navigation gyroscopes, a < 1 marcs star tracking telescope, and other essential technologies were developed as a result of an intensive collaboration between Stanford physicists and engineers, NASA and industry. Gravity Probe B collected science data from August 27, 2004 through September 29, 2005. Analysis of the data began during the mission and is on-going. This paper describes the main features and challenges of the experiment and presents the preliminary results to date.

  16. Early detection of breast cancer: results of a screening programme

    1980-01-01

    The results of a mammography screening programme launched by the American Cancer Society and the National Cancer Institute are discussed. Twenty-seven Breast Cancer Detection Demonstration Projects (BCDDP) screened 280,000 women annually for 5 years. During the first 2 screenings, 1810 cancers were detected. An increased rate of discovery in all age groups was achieved. The radiation risk of mammography is also discussed. The results of the BCDDP were evaluated by a review panel. Of the 1810 cancers detected, 45% had been detected by mammography alone, 47% by mammography and physical examination and only 7% by physical examination alone. 592 of the cancers were < 1 cm in diameter. Two-thirds of these lesions were considered to be in-situ carcinoma and one-third invasive cancer. In 66 instances, the tissue first presented was considered not to be cancerous; these cases were further studied clinically and pathologically. It is concluded that, in the experience of the BCDDP, mammography proved to be an excellent method of detection, but it does have a small theoretical risk. As a widely used approach to detection, mammography is probably not practical due to the number of experts necessary for image evaluation. (UK)

  17. Early Results and Spaceflight Implications of the SWAB Flight Experiment

    Microbial monitoring of spacecraft environments provides key information in the assessment of infectious disease risk to the crew. Monitoring aboard the Mir space station and International Space Station (ISS) has provided a tremendous informational baseline to aid in determining the types and concentrations of microorganisms during a mission. Still, current microbial monitoring hardware utilizes culture-based methodology which may not detect many medically significant organisms, such as Legionella pneumophila. We hypothesize that evaluation of the ISS environment using non-culture-based technologies would reveal microorganisms not previously reported in spacecraft, allowing for a more complete health assessment. To achieve this goal, a spaceflight experiment, operationally designated as SWAB, was designed to evaluate the DNA from environmental samples collected from ISS and vehicles destined for ISS. Results from initial samples indicate that the sample collection and return procedures were successful. Analysis of these samples using denaturing gradient gel electrophoresis and targeted PCR primers for fungal contaminants is underway. The current results of SWAB and their implication for in-flight molecular analysis of environmental samples will be discussed.

    The Far Infrared Absolute Spectrophotometer (FIRAS) on the Cosmic Background Explorer (COBE) mapped 98 percent of the sky, 60 percent of it twice, before the liquid helium coolant was exhausted. The FIRAS covers the frequency region from 1 to 100/cm with a 7 deg angular resolution. The spectral resolution is 0.2/cm for frequencies less than 20/cm and 0.8/cm for higher frequencies. Preliminary results include: a limit on the deviations from a Planck curve of 1 percent of the peak brightness from 1 to 20/cm, a temperature of 2.735 +/- 0.06 K, a limit on the Comptonization parameter y of 0.001, on the chemical potential parameter mu of 0.01, a strong limit on the existence of a hot smooth intergalactic medium, and a confirmation that the dipole anisotropy spectrum is that of a Doppler shifted blackbody.

CONCLUSION: The DFDB is an online database for registration of fracture-related surgery that allows for basic quality assessment of surgical fracture treatment and large-scale observational...

    with an accuracy of 0.4 muGal corresponding to 9 mm water thickness on spatial scales longer than 1300 km. Four of the most widely used global hydrological models have been investigated for their spatial comparison with GRACE observations of inter-annual gravity field variations due to changes in continental water...... storage. The Global Land Data Assimilation System model has a spatial correlation coefficient with GRACE observations of 0.65 over the northern hemisphere. This demonstrates that the observed gravity field changes on these scales are largely related to changes in continental water storage.......Fifteen monthly gravity field solutions from the GRACE twin satellites launched more than two years ago have been studied to estimate gravity field changes between 2002 and 2003. The results demonstrate that GRACE is capable of capturing the changes in ground water on inter-annual scales...

    The first LHC pp collisions at centre-of-mass energies of 0.9 and 2.36 TeV were recorded by the CMS detector in December 2009. The trajectories of charged particles produced in the collisions were reconstructed using the all-silicon Tracker and their momenta were measured in the 3.8 T axial magnetic field. Results from the Tracker commissioning are presented including studies of timing, efficiency, signal-to-noise, resolution, and ionization energy. Reconstructed tracks are used to benchmark the performance in terms of track and vertex resolutions, reconstruction of decays, estimation of ionization energy loss, as well as identification of photon conversions, nuclear interactions, and heavy-flavour decays.

  2. Early Run 2 Hard QCD Results from the ATLAS Collaboration

    Full Text Available We provide an overview of hard QCD results based on data collected with the ATLAS detector in proton-proton collision at √s = 13 TeV at the Large Hadron Collider. The production of high transverse momentum jets, photons and photon-pairs were studied; the inclusive jet cross section is found to agree well with the prediction of perturbative QCD calculations performed at next-to-leading accuracy. The production cross sections for W and Z bosons in their e and μ decays was measured; in general, agreement is found with the expectation of next-to-next-to leading order QCD calculations and interesting sensitivities to the proton structure functions are already observed. The top production cross sections were measured in different top decay channels and found to agree with the state of the art QCD predictions.

    Results of 74 patients treated by primary radiation therapy with curative intent at the Tata Memorial Hospital between January 1980 and December 1984 are reported. Thirty three (44.6%) were classified as TlaNO, twenty five (33.8%) as TlbNO, ten (13.5%) as T2NO and six(8.1%) as TisNO. The 5-year actuarial survival was 92% and disease-free survival was 85%. Thirteen patients (17.5%) failed locally, seven (53.8%) of whom were salvaged by surgery. Radiation side-effects were minimal and there were no long term complications. Anterior commissure involvement did not affect the local recurrence rates. (author). 19 refs., 1 tabs

    Low signal-to-noise ratio (LSNR) detection techniques allow for implementation of airborne light detection and range (LIDAR) instrumentation aboard platforms with prohibitive power, size, and weight restrictions. The University of Florida has developed the Coastal Area Tactical-mapping System (CATS), a prototype LSNR LIDAR system capable of single photon laser ranging. CATS is designed to operate in a fixed-wing aircraft flying 600 m above ground level, producing 532 nm, 480 ps, 3 μJ output pulses at 8 kHz. To achieve continuous coverage of the terrain with 20 cm spatial resolution in a single pass, a 10x10 array of laser beamlets is scanned. A Risley prism scanner (two rotating V-coated optical wedges) allows the array of laser beamlets to be deflected in a variety of patterns, including conical, spiral, and lines at selected angles to the direction of flight. Backscattered laser photons are imaged onto a 100 channel (10x10 segmented-anode) photomultiplier tube (PMT) with a micro-channel plate (MCP) amplifier. Each channel of the PMT is connected to a multi-stop 2 GHz event timer. Here we report on tests in which ranges for known targets were accumulated for repeated laser shots and statistical analyses were applied to evaluate range accuracy, minimum separation distance, bathymetric mapping depth, and atmospheric scattering. Ground-based field test results have yielded 10 cm range accuracy and sub-meter feature identification at variable scan settings. These experiments also show that a secondary surface can be detected at a distance of 15 cm from the first. Range errors in secondary surface identification for six separate trials were within 7.5 cm, or within the timing resolution limit of the system. Operating at multi-photon sensitivity may have value for situations in which high ambient noise precludes single-photon sensitivity. Low reflectivity targets submerged in highly turbid waters can cause detection issues. CATS offers the capability to adjust the

    Purpose: To assess whether the retrograde transpopliteal approach is a safe, practical and effective alternative to femoral puncture for percutaneous transluminal angioplasty (PTA).Methods: Forty PTAs in 38 patients were evaluated. Intentional subintimal recanalization was performed in 13 limbs. Ultrasound evaluation of the popliteal fossa was carried out 30 min and 24 hr post procedurally in the first 10 patients to exclude local complications. All patients had a follow-up of at least 6 weeks.Results: The indication for PTA was critical ischemia in seven limbs and disabling claudication in the remainder.Stenoses (single or multiple) were present in 24 and occlusion in 15.The superficial femoral artery (SFA) was the commonest segment affected(36) followed by common femoral artery (CFA) in four and iliac artery in four. Technical success was achieved in 38 of 39 limbs where angioplasty was carried out. In one limb no lesion was found.Immediate complications were distal embolization in two and thrombosis in one. None of these required immediate surgery. There were no puncture site hematomas or popliteal arteriovenous fistulae.Symptomatic patency at 6 weeks was 85%. Further reconstructive surgery was required in three limbs and amputation in two.Conclusion: The transpopliteal approach has a high technical success rate and a low complication rate with a potential to develop into an outpatient procedure. It should be considered for flush SFA occulsions or iliac disease with tandem CFA/SFA disease where the contralateral femoral approach is often technically difficult

    Adolescence is characterized by an increase in risk-taking and reward-seeking behaviors. In other populations, increased risk taking has been associated with tighter coupling between cortisol production and ventral striatum (VS) activation during reward anticipation; this relation has not yet been examined, however, as a function of adolescent development. This study examined the influence of pubertal development on the association between diurnal cortisol production and VS activity during reward anticipation. Pre- and post-menarcheal girls collected diurnal cortisol and completed an functional magnetic resonance imaging-based monetary incentive delay task, from which we extracted estimates of VS activity during the anticipation of reward, anticipation of loss and anticipation of non-incentive neutral trials. Post-menarcheal girls showed greater coupling between the cortisol awakening response and VS activation during anticipation of reward and loss than did their pre-menarcheal counterparts. Post-menarcheal girls did not differ from pre-menarcheal girls in their cortisol-VS coupling during anticipation of neutral trials, suggesting that puberty-related changes in cortisol-VS coupling are specific to affective stimuli. Interestingly, behavioral responses during the task indicate that post-menarcheal girls are faster to engage with affective stimuli than are pre-menarcheal girls. Thus, post-menarcheal girls exhibit neurobiological and behavioral patterns that have been associated with risk taking and that may underlie the dramatic increase in risk-taking behavior documented during adolescence. © The Author (2015).

  7. Secular trends in age at menarche among Caboclo populations from Pará, Amazonia, Brazil: 1930-1980.

    The present study is part of a large research project on growth, development, nutrition, and health of Caboclo populations from the Brazilian Amazon. The aim of this paper is to analyze the age of menarche in adolescents (N=164) and adult women (219) in the studied populations. Caboclo are admixed rural, peasant groups that live along the Amazon river and its tributaries, and there are few previous studies about them. Probit analysis of the status quo data yielded a median age at menarche of 12.29+/-1.76 years. The retrospective method was applied to recall data of the 77 post-menarcheal adolescents, yielding an average of 13.06+/-1.27 years. Number of children in the family did not show any statistical influence on age at menarche in any age group. In adult women, age at menarche decreased from 14.50 in those born in 1930 to 12.88 for those born in 1980 (F=4.371, P=0.001). The downward trend found was, on average, 0.237 year per decade in the study period. The median age at menarche in the adolescents (12.29 years) is one of the lowest values found for Central and South American populations. In the ecological context, a low age at menarche could be an adaptive advantage because it provides a greater chance for reproduction at a young age in an environment where, until recently, life expectancy was low. As has been reported for other developing countries, the change found in age at menarche in the women born from the 1930s to the 1980s is likely to be related to changes in health and nutritional factors that occurred in Brazil because this country experienced significant improvement in living standards related to education, vaccination, and health conditions, which, although not equally, reached all regions after the 1960s.

    Menarche is a critical time point for diverging fates of mammary cells of origin. African American women have young age at menarche, which could be associated with their high rates of estrogen receptor-negative (ER-) breast cancer. In the AMBER Consortium, using harmonized data from 4426 African American women with breast cancer and 17 474 controls, we used polytomous logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for ages at menarche and first live birth (FLB), and the interval between, in relation to ER+ and ER- breast cancer. All statistical tests were two-sided. Risk of ER- breast cancer was reduced with later age at menarche among both parous and nulliparous women (≥15 vs fashion (OR for 20 year interval = 1.39, 95% CI = 1.08 to 1.79, P trend = .003), ER- risk was only increased for intervals up to 14 years and not beyond (P trend = .33). While ER- breast cancer risk was markedly reduced in women with a late age at menarche, there was not a clear pattern of increased risk with longer interval between menarche and FLB, as was observed for ER+ breast cancer. These findings indicate that etiologic pathways involving adolescence and pregnancy may differ for ER- and ER+ breast cancer. © The Author 2015. Published by Oxford University Press.

    textabstractAge at menarche is a marker of timing of puberty in females. It varies widely between individuals, is a heritable trait and is associated with risks for obesity, type 2 diabetes, cardiovascular disease, breast cancer and all-cause mortality. Studies of rare human disorders of puberty and animal models point to a complex hypothalamic-pituitary-hormonal regulation, but the mechanisms that determine pubertal timing and underlie its links to disease risk remain unclear.

    To assess the nutritional status and risk factors of undernutrition in post-menarcheal girls in rural northern Bangladesh. Cross-sectional data on anthropometric measurements, dietary intake, work activity, morbidity and socio-economic status were collected from 12- to 19-year-old primigravidae (n 209) and never-pregnant adolescents (n 456) matched on age and time since menarche. Multiple regression analyses were conducted to determine predictors of stunting, thinness, upper-arm muscle (UAMZ) and fat area Z-scores (UAFZ) among the adolescent girls. A large proportion of adolescents (49 %) were stunted (height-for-age Z-score <-2) and underweight (40 %; weight-for-age Z-score <-2), but not thin (BMI-for-age <5th percentile; approximately 10 %). The mean (sd) UAMZ and UAFZ of the adolescent girls was -0.3 (0.64) and -0.9 (0.40), respectively. Lean mass increased whereas fat mass declined with age. Both stunting and thinness were positively associated with age and time since menarche (P < 0.05). Young age (12-14 years) and literacy were protective against stunting among pregnant adolescents (OR = 0.29, 95 % CI 0.09, 0.88 and OR = 0.50, 95 % CI 0.26, 0.96, respectively). Having symptoms of diarrhoea or dysentery (OR = 7.40, 95 % CI 1.43, 38.29) predicted thinness and was associated with lower UAMZ and UAFZ among never-pregnant girls (both P < 0.05). Performing light-to-moderate activities was protective against thinness among never-pregnant girls (OR = 0.43, 95 % CI 0.22, 0.82), whereas pregnant adolescents who performed high levels of strenuous activities had greater UAMZ (P < 0.05). Undernutrition was widespread among this post-menarcheal adolescent population. Younger and literate adolescents were less likely to be stunted, whereas thinness and body composition were associated with morbidity and work activity.

    Isolated premature menarche is isolated or recurrent vaginal bleeding in a female in the absence of appropriate secondary sexual characters. Retrospective chart review of patients with premature menarche, followed by a telephone questionnaire. Charts of patients evaluated in the Pediatric Endocrine Clinic for premature vaginal bleeding from 1982-2013 were reviewed. Of 21 patients identified, 17 could be contacted. Five newly diagnosed patients were recruited during the course of the study. The median age at initial presentation was 7 years. Most patients presented with Tanner I sexual development. Some had more advanced breast staging, which regressed later. All had prepubertal baseline and stimulated gonadotropins. Most of the patients reported a single or few episodes of menses. Two reported continuation of irregular bleeding into adulthood. All reported an adult height within the midparental target height. Premature menarche in the absence of other appropriate secondary sexual characteristics is a benign entity. Most patients have a few isolated episodes of menses that stop spontaneously; some may continue to have periods into adulthood. Unlike true puberty, these patients do not demonstrate advanced skeletal maturation, and the adult height is normal. Fertility appears to be normal. © 2015 S. Karger AG, Basel.

    Although the relationships between economic conditions and biological variables over the past two centuries in Poland are reasonably well-documented, the influence of economic and political disruptions, including nutritional privation, during the years immediately before, during and shortly after World War II (WWII) has received less attention. This paper considers the association between age at menarche and body size of university students born before, during and after WWII and father's level of education, a commonly used indicator of family economic status in Poland. Subjects were 518 university students surveyed between 1955 and 1972, birth years 1931 through 1951. The sample was divided into three birth cohorts: before (n=237), during (n=247) and after (n=34) WWII. Age at menarche was compared among birth cohorts, and by weight status and father's level of education. Age at menarche increased slightly but significantly among women born during WWII (14.4 yrs) compared to those born before (14.2 yrs) and after (13.9 yrs) the war. Controlling for year of birth and age of the student, age at menarche was significantly earlier in overweight (13.42±0.35 yrs) than in normal weight (14.33±0.06 yrs) and thin (14.54±0.21 yrs) women. Adjusted mean ages at menarche in small samples of overweight women did not differ by father's level of education, and were earlier than corresponding ages of thin and normal weight women. Adjusted mean ages at menarche did not differ between thin and normal weight women with fathers having primary or no education, but were slightly later in thin than in normal weight women with fathers having a vocational, secondary or higher education. Although age at menarche was associated with father's level of education, young adult weight status was a somewhat more important correlate. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study aimed to explore the menarche and menstruation experiences of young females aged 10-12 years in elementary education in Taiwan. Menarche is a significant milestone in a woman's life and for female adolescents it is a sharply defined biological event that can be a traumatic and uncomfortable time. If used, school nurses can make a significant contribution in educating young people and help to ameliorate these problems. Understanding how young women feel about menstruation is a central element to sexual health education practice. A qualitative research design was employed using focus groups. Data were collected from 20 female students, aged between 10-12 years. Focus groups were recorded, transcribed and subject to a thematic analysis. Three themes emerged from the data analysis reflecting the menstrual experience of participants. These were: 'Changing bodies: the physical effects of menarche and menstruation', 'Emotional issues: the psychological impact of menarche and menstruation' and 'Social dimensions of the menarche and menstruation'. Our findings show that young females can experience significant physical and emotional difficulties around menstruation - many of which stem from poor information and the reactions of their peer group to menstrual activity. The potential for school nurses to contribute to this education is significant and schools should explore the manner in which nurses can contribute to this area of health education. Nurses involved in health education work with young people and ensure that menstruation education addresses the social and psychological impact of the menarche as well as the physical elements of menstruation. Boys should not be absent from this education and the impact of their attitudes towards menstruation upon their female peers should be addressed in health education work.

    This study aimed to exhibit the effects of early physiotherapy and discusses post-treatment results on a patient with incontinentia pigmenti (IP) with encephalocele. Physiotherapy evaluations of the child included cognitive, fine and gross motor development assessed with the Bayley Scales of Infant and Toddler Development – Third Edition (Bayley-III), disability level with the gross motor function classification system, gross motor function with the gross motor function measurement (GMFM), and tonus evaluation with the Modified Ashworth Scale. The child was included in a physiotherapy and rehabilitation programme based on neurodevelopmental treatment three times a week. Although cognitive and motor development according to Bayley-III improved in the present case, motor and cognitive retardation became more apparent with growth. GMFM results indicated a large improvement from 5.88% to 47.73%. Presentation of this case shows the significance of early physiotherapy in this first study on physiotherapy for IP during the early rehabilitation process. PMID:22767665

    OBJECTIVE: To determine how early puberty and peer deviance relate to trajectories of aggressive and delinquent behavior in early adolescence and whether these relationships differ by race/ethnicity. METHODS: In this longitudinal study, 2607 girls from 3 metropolitan areas and their parents were interviewed at ages 11, 13, and 16 years. Girls reported on their age of onset of menarche, best friend’s deviant behavior, delinquency, and physical, relational, and nonphysical aggression. Parents provided information on family sociodemographic characteristics and girls’ race/ethnicity. RESULTS: Sixteen percent of girls were classified as early maturers (defined by onset of menarche before age 11 years). Overall, relational and nonphysical aggression increased from age 11 to age 16, whereas delinquency and physical aggression remained stable. Early puberty was associated with elevated delinquency and physical aggression at age 11. The relationship with early puberty diminished over time for physical aggression but not for delinquency. Best friend’s deviant behavior was linked with higher levels of all problem behaviors, but the effect lessened over time for most outcomes. Early puberty was associated with a stronger link between best friend’s deviance and delinquency, suggesting increased vulnerability to negative peer influences among early-maturing girls. A similar vulnerability was observed for relational and nonphysical aggression among girls in the “other” racial/ethnic minority group only. CONCLUSIONS: Early puberty and friends’ deviance may increase the risk of problem behavior in young adolescent girls. Although many of these associations dissipate over time, early-maturing girls are at risk of persistently higher delinquency and stronger negative peer influences. PMID:24324002

    Full Text Available Introduction: Malnutrition is particularly prevalent in Intensive Care Units (ICU and associated with poor clinical outcomes. Enteral nutrition (EN has multiple benefits in critically ill patients, particularly when started early at the ICU. A series of studies corroborate this fact; however, other studies present conflicting results. Objective: To assess the clinical results of ICU patients receiving EN, according to EN starting time (early versus late. Patients and method: Basic variables were recorded in all ICU patients who received NE along the study period, as well as time from ICU admission to the start of EN, ICU length of stay, characteristic gastrointestinal complications of EN (gastric residue, constipation, diarrhea, vomiting, regurgitation, abdominal distension and bronchoaspiration and mortality. Results: There was a significant association between early EN and mortality reduction. However, there were no differences in ICU length of stay according to EN starting time. The most frequent complications in the sample were high gastric residue (17.9%, abdominal distension (22.5% and constipation (42.2%. However, no significant differences were observed as a function of the EN starting time. Discussion: Our results, although discrepant at times, do not contradict with those of other studies. EN has shown to be effective as a therapeutic strategy. Therefore, it is recommended the early start of EN in the ICU.

    To understand the status and correlative factors on menarche and first spermatorrhea among children and adolescents, in Chongqing, in order to provide theoretical basis for carrying out sex and health education in this population. By random stratified and cluster sampling, 10 498 students (5 372 boys and 5 126 girls), 5 to 18 years old and living in Chongqing urban districts, were enrolled. General situation and physical features of the population were studied. Statistics analysis system included logistic regression methods, t-test and chi-square test. For urban kids, first experience of spermatorrhea was 0.218 years later than those living in the rural areas (Z=-73.287,P0.05). However, significant difference appeared in average family income (χ(2)=6.175,P=0.046) between two groups of girls. Data from the logistic analysis showed that BMI, hip circumference, height, weight, number of children in the family, time of sleep and the diet structure were associated with menarche. Correlative factors of boys' first spermatorrhea would include: high-energy snacks, hip circumference, weight, height, school type and mother' s education level (Psleep.

    Menstruation is a natural physiological process that requires proper management. Unlike other normal bodily processes, menstruation is linked with religious and cultural meanings that can affect the perceptions of young girls as well as the ways in which the adults in the communities around them respond to their needs. This review aims to answer the following questions: (1) how knowledgeable are adolescent girls in low- and middle-income countries about menstruation and how prepared are they for reaching menarche, (2) who are their sources of information regarding menstruation, (3) how well do the adults around them respond to their information needs, (4) what negative health and social effects do adolescents experience as a result of menstruation, and (5) how do adolescents respond when they experience these negative effects and what practices do they develop as a result? Using a structured search strategy, articles that investigate young girls' preparedness for menarche, knowledge of menstruation and practices surrounding menstrual hygiene in LMIC were identified. A total of 81 studies published in peer-reviewed journals between the years 2000 and 2015 that describe the experiences of adolescent girls from 25 different countries were included. Adolescent girls in LMIC are often uninformed and unprepared for menarche. Information is primarily obtained from mothers and other female family members who are not necessarily well equipped to fill gaps in girls' knowledge. Exclusion and shame lead to misconceptions and unhygienic practices during menstruation. Rather than seek medical consultation, girls tend to miss school, self-medicate and refrain from social interaction. Also problematic is that relatives and teachers are often not prepared to respond to the needs of girls. LMIC must recognize that lack of preparation, knowledge and poor practices surrounding menstruation are key impediments not only to girls' education, but also to self-confidence and personal

    We have previously described the experience, rationale, and development of a valve preserving technique, but its role in patients with Marfan syndrome has not previously been defined. Here, we attempt to determine the early and long-term results, timing, and determinants of outcome of this operation in patients with Marfan syndrome. Since 1979, 82 patients (73.2% of all patients with Marfan syndrome undergoing resection of aneurysm of the ascending aorta) were operated on using this technique. Ages ranged from 2 to 69 years (mean, 33.9 years). In all, there were 4 early deaths (4.9%), 2 with acute dissection and 2 with chronic aneurysm operated on as emergencies. There were no early deaths in 67 patients operated on electively. Actuarial survival for patients operated for chronic aneurysm was 94.2%, 94.2%, and 94.2% at 1, 5, and 10 years, respectively; that for acute dissection was 72.7%, 63. 6%, and 63.6%; and that for chronic dissection was 100%, 85.7%, and 75.0%. The probability of needing reoperation was 5.7%, 17.3%, and 17.3% at 1, 5, and 10 years. There were no instances of infective endocarditis or thromboembolic complications except in 2 patients operated on early in the series who had cusp extension. At the end of the follow-up, trivial or no aortic regurgitation was demonstrated in 33.3%, mild in 45.6%, moderate in 21.1%, and severe in 0. Valve-sparing operations are feasible in most patients with Marfan syndrome; they are applicable to patients with both dissection and chronic aneurysm. The early and long-term results are encouraging. Results are better in the absence of dissection, and prophylactic operation is warranted in some cases.

    Papers presented at the May 27, 1981 meeting of the American Geophysical Union concerning early results from the Magsat satellite program, which was designed to study the near-earth magnetic fields originating in the core and lithosphere, are discussed. The satellite was launched on October 30, 1979 into a sun-synchronous (twilight) orbit, and re-entered the atmosphere on June 11, 1980. Instruments carried included a cesium vapor magnetometer to measure field magnitudes, a fluxgate magnetometer to measure field components and an optical system to measure fluxgate magnetometer orientation. Early results concerned spherical harmonic models, fields due to ionospheric and magnetospheric currents, the identification and interpretation of fields from lithospheric sources. The preliminary results confirm the possibility of separating the measured field into core, crustal and external components, and represent significant developments in analytical techniques in main-field modelling and the physics of the field sources.

  7. Can the observed association between serum perfluoroalkyl substances and delayed menarche be explained on the basis of puberty-related changes in physiology and pharmacokinetics?

    An association between serum levels of two perfluoroalkyl substances (PFAS) and delayed age at menarche was reported in a cross-sectional study of adolescents. Because perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have half-lives of years, growth dilution and the development of a new route of excretion (menstruation) could account for some or all of the reported association. To assess how much of the epidemiologic association between PFAS and delayed menarche can be explained by the correlation of growth and maturation with PFAS body burden. We developed a Monte Carlo (MC) physiologically-based pharmacokinetic (PBPK) model of PFAS to simulate plasma PFAS levels in a hypothetical female population aged 2 to 20years old. Realistic distributions of physiological parameters as well as timing of growth spurts and menarche were incorporated in the model. The association between PFAS level and delayed menarche in the simulated data was compared with the reported association. The prevalence of menarche, distributions of age-dependent physiological parameters, and quartiles of serum PFAS concentrations in the simulated subjects were comparable to those reported in the epidemiologic study. The delay of menarche in days per natural log increase in PFAS concentrations in the simulated data were about one third as large as the observed values. The reported relationship between PFAS and age at menarche appears to be at least partly explained by pharmacokinetics rather than a toxic effect of these substances. Copyright © 2015 Elsevier Ltd.

  8. Disruption of the Sec24d gene results in early embryonic lethality in the mouse.

    Directory of Open Access Journals (Sweden)

    Andrea C Baines

    Full Text Available Transport of newly synthesized proteins from the endoplasmic reticulum (ER to the Golgi is mediated by the coat protein complex COPII. The inner coat of COPII is assembled from heterodimers of SEC23 and SEC24. Though mice with mutations in one of the four Sec24 paralogs, Sec24b, exhibit a neural tube closure defect, deficiency in humans or mice has not yet been described for any of the other Sec24 paralogs. We now report characterization of mice with targeted disruption of Sec24d. Early embryonic lethality is observed in mice completely deficient in SEC24D, while a hypomorphic Sec24d allele permits survival to mid-embryogenesis. Mice haploinsufficient for Sec24d exhibit no phenotypic abnormality. A BAC transgene containing Sec24d rescues the embryonic lethality observed in Sec24d-null mice. These results demonstrate an absolute requirement for SEC24D expression in early mammalian development that is not compensated by the other three Sec24 paralogs. The early embryonic lethality resulting from loss of SEC24D in mice contrasts with the previously reported mild skeletal phenotype of SEC24D deficiency in zebrafish and restricted neural tube phenotype of SEC24B deficiency in mice. Taken together, these observations suggest that the multiple Sec24 paralogs have developed distinct functions over the course of vertebrate evolution.

    A 13-year-old nulligravida girl, 158.5 cm in height and 76.0 kg in body weight, came to our department complaining of continuous right lower abdominal pain. One month earlier, an ovarian cyst in the right ovary, about 3 cm in diameter, was found when she underwent appendectomy at another hospital, but was left untreated. Menarche occurred at the age of 13 years and 1 month, which was after the appendectomy and 24 days before the present operation. Right hematosalpinx with peripheral obstruction and a para-ovarian serous cyst on the same side were diagnosed, and therefore right salpingectomy with para-ovarian cyst resection was performed. The bilateral ovaries and uterus were completely normal by inspection. The post operative histological examination confirmed hematosalpinx and revealed tubal endometriosis.

    Full Text Available Urethral caruncle (UC is a benign fleshy outgrowth at the urethral meatus. It was first described by Samuel Sharp in 1750 and occurs mainly at the posterior lip of the urethra, and the exact aetiology is still uncertain. More often it was seen in the postmenopausal women, and only few cases are reported in young girls. Patients may be asymptomatic and could find this as an incidental finding or they may present with symptoms such as dysuria, bleeding per vagina, haematuria, a mass protruding through vagina, and acute retention of urine. Here, we report the case history of a 4-year-old girl presented with vaginal bleeding which was taken as she has attended menarche and found to have urethral caruncle which was the cause for bleeding. Histology confirmed the diagnosis, and girl was completely cured following surgical excision.

    2008-01-01

    This overview details the persistence of negative characterizations of the menstrual cycle as a feature of the current cultural context in which girls begin menstrual life in the United States. In addition, research on girls' current menstrual attitudes and experiences within this context are reviewed. Current research suggests that girls are not very knowledgeable about menstruation, and that menstrual education continues to provide girls with mixed messages, such as: menstruation is a normal, natural event, but it should be hidden. Girls' attitudes and expectations about menstruation are negatively biased and have been found to contribute to self-objectification, body shame, and lack of agency in sexual decision-making. Although preparation has been found to be associated with more positive menarcheal and menstrual experiences, specificity about what constitutes "good" preparation has not been well articulated. Implications for promoting the menstrual cycle among young girls as a vital sign in service of monitoring their health are discussed.

Results: Ramadan fasting induces a significant decrease in BMI and weight on fasted group (p=0.005, p=0.044, respectively while a significant increase was observed in non-fasted group (p<0.001. Although, T3 decreased significantly by fasting (p<0.001, it remained in the normal range. Hence, T4 decreased and TSH increased slightly in both groups. Conclusions: According to our findings, despite a significant reduction of T3 in fasting group, variation in thyroid hormones level remained in the normal range during Ramadan fasting.

    Retrospective chart review. To determine the efficacy of adjuvant cryotherapy in the treatment of early glottic cancer and laryngeal papillomatosis. The use of cryotherapy in conjunction with traditional modalities has recently been proposed to improve voice outcomes in patients with early laryngeal cancer as compared to pretreatment conditions. This study investigates its utility in improving oncological outcomes and decreasing recurrences of laryngeal papillomatosis. Patients with either early glottic cancer or laryngeal papillomatosis that received cryotherapy as part of their surgical regimen were investigated. All patients were seen at a large tertiary care center within a 10-year window. Demographic data were collected and all postoperative notes were reviewed. Recurrences of the laryngeal cancer were noted, as was the duration of time between successive papillomatosis operations. The charts of 54 glottic cancer and 29 papillomatosis patients that received cryotherapy were reviewed. One patient from the papillomatosis cohort was excluded from statistical analysis due to lack of follow-up. Overall, 16 (30%) of the laryngeal cancer patient experienced a malignant recurrence. The overall 5-year survival of these patients was 98% and the 5-year disease-free survival was 74%. The use of adjuvant cryotherapy in the treatment of laryngeal papillomatosis extended the duration of time between surgeries by an average of 79 days (P=.23). The use of adjuvant cryotherapy in the treatment of early glottic cancer does not improve the rate of carcinoma recurrences. Additionally, cryotherapy does not result in a statistically significant increase in the duration of disease-free period for laryngeal papillomatosis patients, although the observed increase may be clinically important. © The Author(s) 2015.

  16. Higgs couplings and supersymmetry in the light of early LHC results

    We present phenomenological studies investigating the implications of early results from the Large Hadron Collider (LHC) for models beyond the Standard Model (BSM), mostly focusing on Supersymmetry (SUSY). Our work covers different aspects in this wide field of research. We describe the development and basic concepts of the public computer codes HiggsBounds (version 4) and HiggsSignals. These confront the Higgs sector predictions of BSM models with results from LEP, Tevatron and LHC Higgs searches. While HiggsBounds tests the model against experimental null-results, HiggsSignals evaluates the model's chi-squared compatibility with the signal rate and mass measurements of the Higgs boson, that was discovered by the LHC in 2012. We then perform a systematic study of potential deviations in the Higgs couplings from their Standard Model (SM) prediction. No significant deviations are found. Future capabilities of Higgs coupling determination at the later LHC stages and at the International Linear Collider (ILC) are explored. We also study the implications of the Higgs discovery for the Minimal Supersymmetric Standard Model (MSSM), considering either the light or the heavy CP-even Higgs boson as the discovered state. We show that both interpretations are viable and discuss their phenomenology. Finally, we study the LHC signatures of resonant scalar lepton production, which may arise in SUSY models with R-parity violation (RPV). These are confronted with early LHC results, yielding constraints on the relevant RPV operators.

    sexualidad sean ampliadas, alcanzando a un número mayor de participantes a partir del grupo etáreo de 9 años.OBJECTIVE: To know the meaning of menarche for adolescents in schools in the region of Saint Edward, in the municipality of Embu das Artes, São Paulo (Brazil. METHODS: This was qualitative research, with data collected by a focus group technique and with the content of the narratives outlined by means of content analysis. RESULTS: The results were classified into five categories represented as: fertility; repercussions; menstruation and taboo; the fear of dying; and, misinformation and impact. CONCLUSION: For the adolescents interviewed, menarche was reported as a negative experience, related to feelings of fear and anguish. This view was attributed to social, historical and cultural constructs that do not value dialogue and questions relating to the body. Thus, it emphasizes the importance of demystifying the theme and recommends that sexuality education interventions should be expanded, to reach a larger number of participants beginning at the age of 9 years.

    Full Text Available Pressure garment therapy is often prescribed to improve scar properties following full-thickness burn injuries. Pressure garment therapy is generally recommended for long periods of time following injury (1-2 years, though it is plagued by extremely low patient compliance. The goal of this study was to examine the effects of early cessation of pressure garment therapy on scar properties. Full-thickness burn injuries were created along the dorsum of red Duroc pigs. The burn eschar was excised and wound sites autografted with split-thickness skin. Scars were treated with pressure garments within 1 week of injury and pressure was maintained for either 29 weeks (continuous pressure or for 17 weeks followed by cessation of pressure for an additional 12 weeks (pressure released; scars receiving no treatment served as controls. Scars that underwent pressure garment therapy were significantly smoother and less contracted with decreased scar height compared to control scars at 17 weeks. These benefits were maintained in the continuous pressure group until week 29. In the pressure released group, grafts significantly contracted and became more raised, harder and rougher after the therapy was discontinued. Pressure cessation also resulted in large changes in collagen fiber orientation and increases in collagen fiber thickness. The results suggest that pressure garment therapy effectively improves scar properties following severe burn injury; however, early cessation of the therapy results in substantial loss of these improvements.

    Full Text Available Aim: Our aim was to identify the characteristics of the patient that performed upper gastrointestinal endoscopy in a new established endoscopy unit of a state hospital. We want to present the spectrum of gastrointestinal diseases in our hospitals region. Material and Method: We analyzed patients upper endoscopy results according to age, sex, complaints, clinical characteristics, type of anesthesia, and the necessity of biopsy. We reviewed 256 patients data between 2013 December-2014 July. All endoscopies were performed by same surgeon. Results: The highest complaint was epigastric pain (n=112, 43, 8%. Other complaints were followed as dyspepsia (n=84, 32.8%, heartburn (n=42, 16.4%, nausea (n=4, 1.6%, vomiting (n=2, 0.8%, dysphagia (n=6, 2.3%. We determined 218 gastritis (85.2%, 64 hiatal hernia (25%, 120 esophagitis (46.9%, 76 duodenitis (29.7%, 4 gastric ulcer (1.6%, 18 duodenal ulcers (7%, 20 bile reflux (7.8%, 26 Gastro esophageal reflux disease (GERD in patients (10.2%. 10 patients reported as normal (3.9%. Biopsy was performed in 186 of the patients. Discussion: Endoscopy can become an early diagnostic examination by increasing the availability of endoscopy. Also alarm symptoms should not be ignored and endoscopy should perform immediately in symptomatic patients. As an early result of upper gastrointestinal endoscopies that performed in this study; gastritis, esophagitis, duodenitis and hiatal hernia are common gastrointestinal diseases in our region.

    Full Text Available Introduction: A female encounters various menstrual disorders from puberty to menopause. We evaluated menstrual disturbances in post-menarche age and young adult age. Aim: To know the prevalence and impact of menstrual abnormalities at early adolescent and young adult age and to evaluate course of disorders identified at early adolescent age. Materials and Methods: A cross-sectional survey was carried out through self-administered questionnaire on 367 consented students at Melaka Manipal Medical College at Manipal, during December 2015- April 2016. Data were analysed by Statistical Package for the Social Sciences (SPSS 16.0 software. Results: Prevalence and pattern of menstrual disorders at early adolescent and at young adult age were noted. The mean age of menarche was 12.1 ±1.1 years. Menorrhagia was the most frequent (14.7% and 11.7% and polymenorrhea (7.6 % and 6% was least frequent menstrual disorder at adolescent age and young adult age respectively. Resolution of pubertal menstrual disorders was observed in all disorders, but noticed highest in oligomenorrhea (91%, (p-value <0.05. Prevalence of menstrual related disorder like dysmenorrhea was 88.7% at adolescent age and 67.6% at the young adult age. It was statistically significant reduction. Hindrance in academic performance and social behavior was noted more at young adult age, which was in 23.9% and 46.7% respectively (p-value <0.05. Conclusion: The most prevalent menstrual abnormality was menorrhagia at the early adolescent and the young adult age. Associated the most prevalent menstrual related symptoms were dysmenorrhea at early adolescent age, and premenstrual symptom at the young adult age. The study demonstrates the natural course (decreasing prevalence of all menstrual disorders from early adolescent to young adult age.

    Using 3.6 μm images of 97 early-type galaxies, we develop and verify methodology to measure globular cluster populations from the S{sup 4}G survey images. We find that (1) the ratio, T {sub N}, of the number of clusters, N {sub CL}, to parent galaxy stellar mass, M {sub *}, rises weakly with M {sub *} for early-type galaxies with M {sub *} > 10{sup 10} M {sub ☉} when we calculate galaxy masses using a universal stellar initial mass function (IMF) but that the dependence of T {sub N} on M {sub *} is removed entirely once we correct for the recently uncovered systematic variation of IMF with M {sub *}; and (2) for M {sub *} < 10{sup 10} M {sub ☉}, there is no trend between N {sub CL} and M {sub *}, the scatter in T {sub N} is significantly larger (approaching two orders of magnitude), and there is evidence to support a previous, independent suggestion of two families of galaxies. The behavior of N {sub CL} in the lower-mass systems is more difficult to measure because these systems are inherently cluster-poor, but our results may add to previous evidence that large variations in cluster formation and destruction efficiencies are to be found among low-mass galaxies. The average fraction of stellar mass in clusters is ∼0.0014 for M {sub *} > 10{sup 10} M {sub ☉} and can be as large as ∼0.02 for less massive galaxies. These are the first results from the S{sup 4}G sample of galaxies and will be enhanced by the sample of early-type galaxies now being added to S{sup 4}G and complemented by the study of later-type galaxies within S{sup 4}G.

    Common surgical treatment options for isolated patellofemoral osteoarthritis include arthroscopic procedures, total knee replacement and patellofemoral replacement. The HemiCap Wave patellofemoral resurfacing prosthesis is a novel inlay design introduced in 2009 with scarce published data on its functional outcomes. We aim to prospectively evaluate early functional outcomes and complications, for patients undergoing a novel inlay resurfacing arthroplasty for isolated patellofemoral arthrosis in an independent centre. From 2010 to 2013, 16 consecutive patients underwent patellofemoral resurfacing procedures using HemiCap Wave (Arthrosurface Inc., Franklin, Massachusetts, USA) for anterior knee pain with confirmed radiologically and/or arthroscopically isolated severe patellofemoral arthrosis. Standardized surgical technique, as recommended by the implant manufacturer, was followed. Outcome measures included range of movement, functional knee scores (Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Short Form-36 (SF-36)), radiographic disease progression, revision rates and complications. Eight men and eight women underwent patellofemoral HemiCap Wave resurfacing, with an average age of 63 years (range: 46-83). Average follow-up was 24.1 months (6-34). Overall, post-operative scores were excellent. There was a statistically significant improvement in the post-operative OKS, KOOS and SF-36 scores ( p patellofemoral resurfacing prosthesis has excellent early results in terms of functional outcomes, radiological outcomes and low complication rates. At the very least, early results show that the HemiCap Wave is comparable to more established onlay prostheses. The HemiCap Wave thus provides a safe and effective surgical option in the treatment of isolated patellofemoral osteoarthritis in selected patients.

    Early puberty is linked to adverse developmental outcomes in adolescents in Western societies. However, little is known about this relationship in an East Asian context. In addition, whether the impact of subjective pubertal timing (PT) and menarcheal age (MA) on adolescent psychosocial development persists into early adulthood remains unclear and is worthy of investigation. A subset of data was retrieved from the Taiwan Youth Project, which recruited and followed a longitudinal cohort of 7 th - and 9 th -grade female Taiwanese students from 2000 to 2007. Subjective PT was defined using the Pubertal Developmental Scale (PDS), which mainly measures pubertal changes. MA was recalled by participants themselves. Various psychological and behavioral factors were recorded and measured until the age of 20, including the use of alcohol and cigarettes, psychological well-being, sexual activity, and socially problematic behaviors. A χ 2 test for linear-by-linear association and one-way analysis of variance followed by multivariate regression models were used to dissect the differential effects of PT and MA in the association with the outcome variables. In total, 1545 female participants with an average age of 14.5 (±1.1) years were deemed valid for analysis. Among them, 257 (16.6%) participants perceived themselves as having early PT, defined as more than 1 standard deviation above the mean PDS score, and 82 (5.3%) had early MA (occurring before the 4 th grade). In univariate analysis, participants with early PT had higher rates of smoking and sexual activity, and MA was not related to their psychobehavioral outcomes. After multivariate adjustment, only late PT was significantly correlated with lower amounts of cigarette smoking and sexual activity before the age of 20. Conceptual and actual pubertal developments may be differentially associated with psychobehavioral outcomes among young Taiwanese girls. Clinical attention should be given to adolescent self-perception of

    Femoral short stems promise essential advantages in total hip arthroplasty. Up to now, only short- and midterm clinical studies exist. Data on early stem migration that could predict later aseptic loosening at an early stage are rare. The purpose of this study was to assess migration patterns and clinical outcome 2 years after hip replacement by a metaphyseal anchored cementless short stem. Migration data and clinical results were prospectively assessed in 49 patients. Clinical outcome was measured using the Harris Hip Score (HHS). Migration analyses were performed using the computer-assisted Einzel-Bild-Roentgen-Analyse (EBRA) system. At 2 years after surgery, none of the implants needed revision, and HHS increased from 47.9 up to 98.1. Of 49 patients, 5 (10%) showed increased vertical stem migration (1.5 mm/2a) that might predict late aseptic loosening. Of 49 stems, 44 (90%) showed stable migration patterns indicating a beneficial long-term outcome. Results of this study confirm the excellent clinical data of previous works. Migration patterns strongly suggest that short-stem arthroplasty is not only an innovative but also a reliable strategy in total hip replacement.

    Objective: The influence of conservative mastectomy plus postoperative radiation (CM + RT) in local control, distant failure, cosmetic and psychological outcome for early stage breast cancer was evaluated comparing with modified radical mastectomy. Methods: Between January 1998 and December 2003, 68 early stage breast cancer patients underwent CM + RT. During the save period, 76 similar patients were treated by modified radical mastectomy (MRM + RT). The cosmetic results evaluated as 'excellent', 'fair' or 'poor' using specific guide lines together with their psychological changes. Sex life and marital stability were also recorded. All patients were female with median age of 44.5 years (range, 28-62 years). Guidelines for patient selection reported by National Breast Cancer Cooperative Group was adhered to. In general, CM consisted of wide local excision with the breast conserved and postoperative radiotherapy to the entire breast with tangential fields followed by a boost to the tumor bed. All patients also received adjuvant chemotherapy with CAF. Patients with positive ER or PR assay results received tamoxifen for 5 years. In the 76 MRM + RT patients, the post operative radiotherapy and chemotherapy were given as clinically indicated. Results: There was no failure locally in all. In CM + RT group, the cause of failure was bone metastasis in 1 and mutiple metastasis in 2. In the MRM + RT group, the cause of failure was bone metastasis in 2, brain metastasis in 1 and mutiple metastases in 1. The cosmetic scores were 91.2% excellent, 5.6% fair and 2.9% poor. Conclusions: Breast preservation by conservative mastectomy is preferable to mastectomy in appropriately selected patients as it provides equivalent survival but giving good cosmetic results.

    Systematic review of the literature to characterize safety profile and complication rates associated with arthroscopic coracoid transfer procedures. We conducted a combined search of Medline, EMBASE, and the CINAHL databases from 1985 to November 2012. Articles were selected and data extracted according to standard criteria. Only 3 studies met the inclusion criteria, and these originated from the pioneers of this technique. These studies described the results of 172 arthroscopic coracoid transfer procedures with an overall complication rate of 19.8% ± 5.6%. Conversion to open surgery was necessary in 6/172 (3.5%) patients. Repeated surgery was described in 5/172 (2.9% ± 2.5%) cases, all for screw removal. The overall rate of recurrent instability was 3/172 cases (1.7% ± 2%). Hardware-related complications occurred in 4/172 patients (2.3% ± 2.3%). Coracoid grafts failed to unite in 14/172 patients (8.1% ± 4.1%); graft osteolysis was seen in 7/172 patients (4.1% ± 2.6%). The coracoid graft fractured in 2/172 cases (1.2% ± 1.6%); one of these occurred intraoperatively and one occurred early postoperatively. There was one transient nerve palsy (0.6% ± 1.1%). Results of arthroscopic coracoid transfer surgery for anterior shoulder instability are sparse, with the available studies originating from the pioneers of this technique. Early results suggest that arthroscopic coracoid transfer is a technically feasible procedure that is able to restore shoulder stability. However, this technique seems to be associated with a high complication rate and a steep learning curve. Results from the wider orthopaedic shoulder arthroscopic community are awaited. Extensive cadaveric training and experience with the open technique is recommended before performing the arthroscopic procedure. Systematic review of Level IV studies.

    The pre-pubertal socioeconomic environment may be an important determinant of age at menarche, adult height, body proportions and adiposity: traits closely linked to adolescent and adult health. This study explored differences in age at menarche, adult height, relative leg-length and waist circumference between rural and urban black South African young adult women, who are at different stages of the nutrition and epidemiologic transitions. We compared 18-23 year-old black South African women, 482 urban-dwelling from Soweto and 509 from the rural Mpumalanga province. Age at menarche, obstetric history and household socio-demographic and economic information were recorded using interview-administered questionnaires. Height, sitting-height, hip and waist circumference were measured using standardised techniques. Urban and rural black South African women differed in their age at menarche (at ages 12.7 and 14.5 years, respectively). In urban women, a one-year increase in age at menarche was associated with a 0.65 cm and 0.16% increase in height and relative leg-length ratio, respectively. In both settings, earlier age at menarche and shorter relative leg-length were independently associated with an increase in waist circumference. In black South African women, the earlier onset of puberty, and consequently an earlier growth cessation process, may lead to central fat mass accumulation in adulthood.

    The aim of this study was to identify polymorphisms and gene-gene interactions that are significantly associated with age at menarche and age at menopause in a Korean population. A total of 3,452 and 1,827 women participated in studies of age at menarche and age at natural menopause, respectively. Linear regression analyses adjusted for residence area were used to perform genome-wide association studies (GWAS), candidate gene association studies, and interactions between the candidate genes for age at menarche and age at natural menopause. In GWAS, four single nucleotide polymorphisms (SNPs; rs7528241, rs1324329, rs11597068, and rs6495785) were strongly associated with age at natural menopause (lowest P = 9.66 × 10). However, GWAS of age at menarche did not reveal any strong associations. In candidate gene association studies, SNPs with P menopause, there was a significant interaction between intronic SNPs on ADAM metallopeptidase with thrombospondin type I motif 9 (ADAMTS9) and SMAD family member 3 (SMAD3) genes (P = 9.52 × 10). For age at menarche, there were three significant interactions between three intronic SNPs on follicle-stimulating hormone receptor (FSHR) gene and one SNP located at the 3' flanking region of insulin-like growth factor 2 receptor (IGF2R) gene (lowest P = 1.95 × 10). Novel SNPs and synergistic interactions between candidate genes are significantly associated with age at menarche and age at natural menopause in a Korean population.

    Although numerous studies have demonstrated the relationship between maturation and lower extremity biomechanics during landing in team sport athletes, we are presently uninformed of any research that examined the single-legged drop landing biomechanics of gymnasts. The purpose of this study is to investigate the effects of the menarcheal age on the lower extremity biomechanics during a single-legged drop landing in female artistic elite gymnasts. Twenty-two female artistic elite gymnasts, between 9 and 36 years of age, participated in this study. The participants were divided into two groups pre- (n = 11) and post- (n = 11) menarche and asked to perform a single-legged drop landing on top of a 30 cm platform and land on a force plate. The statistical analysis consisted of the multivariate analysis with the level of significance set at p < 0.05. The post-menarche group showed a decrease in their maximum knee flexion angle and increase in their maximum knee abduction angle, maximum internal tibial rotation angle, maximum knee abduction moment, and hamstring-quadriceps muscle activity ratio compared with the pre-menarche group during the single-legged drop landing. The post-menarche group showed an increased noncontact anterior cruciate ligament injury risk, due to their greater knee loads, compared with the pre-menarche group.

  14. Early embryonic chromosome instability results in stable mosaic pattern in human tissues.

    Full Text Available The discovery of copy number variations (CNV in the human genome opened new perspectives on the study of the genetic causes of inherited disorders and the aetiology of common diseases. Here, a single-cell-level investigation of CNV in different human tissues led us to uncover the phenomenon of mitotically derived genomic mosaicism, which is stable in different cell types of one individual. The CNV mosaic ratios were different between the 10 individuals studied. However, they were stable in the T lymphocytes, immortalized B lymphoblastoid cells, and skin fibroblasts analyzed in each individual. Because these cell types have a common origin in the connective tissues, we suggest that mitotic changes in CNV regions may happen early during embryonic development and occur only once, after which the stable mosaic ratio is maintained throughout the differentiated tissues. This concept is further supported by a unique study of immortalized B lymphoblastoid cell lines obtained with 20 year difference from two subjects. We provide the first evidence of somatic mosaicism for CNV, with stable variation ratios in different cell types of one individual leading to the hypothesis of early embryonic chromosome instability resulting in stable mosaic pattern in human tissues. This concept has the potential to open new perspectives in personalized genetic diagnostics and can explain genetic phenomena like diminished penetrance in autosomal dominant diseases. We propose that further genomic studies should focus on the single-cell level, to better understand the aetiology of aging and diseases mediated by somatic mutations.

    Patients with early breast cancer (T1-2 N0-1) can be treated by lumpectomy and irradiation with a local control and survival equal to more radical surgery. Between 1982 and 1988, 323 patients with early breast cancer were treated, when possible, with Ir-192 implants at the time of lumpectomy to a local dose of 2000 cGy in 40-50 hours. Ten to 14 days later, the whole breast was treated to 4500 cGy at 180 per fraction in 5 weeks. The 6-year actuarial survival for stages I and II disease was 98% and 91%, respectively, and the recurrence-free survival was 96% and 98%, respectively. When these 323 patients were evaluated by T status, a local control of 97% was the same for T1 and T2 lesions. The cosmetic results were good to excellent in 95% of the patients. This approach has improved our ability to accurately place the boost dose in the breast

    The aim of this retrospective study was to evaluate our experience of using a simplified aortic valve sleeve procedure to treat aortic root ectasia and aneurysms with or without aortic regurgitation. In experienced hands, 2 aortic valve-sparing procedures, ie, Yacoub and David, have yielded excellent long-term results in the treatment of aortic root aneurysms, with or without aortic regurgitation. However, these techniques are demanding and not widely used. Recently, a new and simplified valve-sparing technique, named "sleeve procedure," has been proposed, and has yielded encouraging early results. Ninety consecutive patients with aortic root aneurysms underwent sleeve procedures from October 2006 to October 2012. Follow-up data (clinical 100% complete and echocardiographic 93% complete) were acquired from our outpatient clinic or from the referring cardiologist. The mean age of the patients was 61.5 ± 12.5 years, 79% were male, 16 (18%) had a bicuspid valve, 3 had Marfan syndrome, and 2 had aortic dissection. Over a mean clinical follow-up of 34 ± 19 months, 2 patients died from noncardiac causes and 1 was reoperated on for the recurrence of aortic regurgitation. On follow-up echocardiography after a mean of 18 ± 9 months, aortic regurgitation was absent/negligible, mild or moderate in 62%, 37%, and 1% of patients, respectively, and the diameters of the annulus, Valsalva sinuses, and sinotubular junction were 27.3 + 2.2, 37.0 + 3.4, and 30.6 + 3.1 mm, respectively. Our encouraging early and medium term results suggest that the sleeve procedure is a safe and effective aortic valve-sparing technique for the treatment of aortic root ectasia and aneurysm. However, longer follow-up is needed in order to draw definitive conclusions. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    Age at menarche (AM) and age at natural menopause (ANM) are complex traits with a high heritability. Abnormal timing of menarche or menopause is associated with a reduced span of fertility and risk for several age-related diseases including breast, endometrial and ovarian cancer, cardiovascular disease, and osteoporosis. To identify novel genetic loci for AM or ANM in East Asian women and to replicate previously identified loci primarily in women of European ancestry by genome-wide association studies (GWASs), we conducted a two-stage GWAS. Stage I aimed to discover promising novel AM and ANM loci using GWAS data of 8073 women from Shanghai, China. The Stage II replication study used the data from another Chinese GWAS (n = 1230 for AM and n = 1458 for ANM), a Korean GWAS (n = 4215 for AM and n = 1739 for ANM), and de novo genotyping of 2877 additional Chinese women. Previous GWAS-identified loci for AM and ANM were also evaluated. We identified two suggestive menarcheal age loci tagged by rs79195475 at 10q21.3 (beta = -0.118 years, P = 3.4 × 10 -6 ) and rs1023935 at 4p15.1 (beta = -0.145 years, P = 4.9 × 10 -6 ) and one menopausal age locus tagged by rs3818134 at 22q12.2 (beta = -0.276 years, P = 8.8 × 10 -6 ). These suggestive loci warrant a further validation in independent populations. Although limited by low statistical power, we replicated 19 of the 98 menarche loci and 5 of the 20 menopause loci previously identified in women of European ancestry in East Asian women, suggesting a shared genetic architecture for these two traits across populations.

    To identify loci for age at menarche, we performed a meta-analysis of 32 genome-wide association studies in 87,802 women of European descent, with replication in up to 14,731 women. In addition to the known loci at LIN28B (P=5.4×10−60) and 9q31.2 (P=2.2×10−33), we identified 30 novel menarche loci (all P<5×10−8) and found suggestive evidence for a further 10 loci (P<1.9×10−6). New loci included four previously associated with BMI (in/near FTO, SEC16B, TRA2B and TMEM18), three in/near other genes implicated in energy homeostasis (BSX, CRTC1, and MCHR2), and three in/near genes implicated in hormonal regulation (INHBA, PCSK2 and RXRG). Ingenuity and MAGENTA pathway analyses identified coenzyme A and fatty acid biosynthesis as biological processes related to menarche timing. PMID:21102462

    Purpose: To assess pathologic control rates for prostatic carcinoma as determined by postimplant prostate biopsy in a large series of consecutive patients who have received permanent interstitial brachytherapy using a contemporary transrectal ultrasound-directed, transperineal, computer generated, volume technique. Methods and Materials: Four hundred and two patients received permanent 125 I or 103 Pd interstitial brachytherapy as primary treatment for early stage prostatic carcinoma at the Northwest Tumor Institute between January 1988 and January 1994. Of these, 201 have consented to biopsy 12 or more months postimplant with a median follow-up of 40 months (range: 12-83 months). None had received homonal manipulation. A total of 361 biopsies was performed on 201 patients with a range of one to six annual biopsies per patient (91 received multiple, serial biopsies). Of the 161 patients more than 12 months postimplant who have not been biopsied, most have been unwilling or unable to submit to biopsy. Only six patients with biochemical progression have not been biopsied. There was no difference in the presenting characteristics or implant parameters between those patients biopsied and those that were not. One hundred and forty-three received 125 I (71%) prescribed to a MPD of 160 Gy with a median activity of 35.5 mCi, and 58 (29%) received 103 Pd prescribed to a MPD of 115 Gy with a median activity of 123 mCi. Multiple biopsies were performed under transrectal ultrasound guidance, and all specimens were classified as either negative, indeterminate, or positive. Results: At the time of last biopsy, 161 (80%) have achieved negative pathology, 34 (17%) remain indeterminate, and 6 (3%) have been positive. Only 2 of the 186 patients with a PSA < 4.0 ng/ml at the time of biopsy were positive. Among those 33 indeterminate patients with a subsequent biopsy, 28 have converted to negative, 2 to positive, and 3 remain unchanged to date. Conclusions: These data demonstrate at

    Children with multiple endocrine neoplasia type 2 (MEN2) often develop medullary carcinoma of the thyroid (MCT) or its precursor, C-cell hyperplasia. Survival results are improved if malignancy is diagnosed early from the results of plasma immunoreactive calcitonin (iCT) measurement. The effect of early detection and thyroidectomy in children with MEN2 syndrome was determined by reviewing the experience between 1975 and 1985. Seventeen children with MEN2 who were 12 years old or younger underwent a total thyroidectomy for MCT or C-cell hyperplasia. iCT was measured in all patients preoperatively and postoperatively. Of the 17 children, 14 (82%) had MEN2a and 3 (18%) had MEN2b. There were 14 (82%) female and three (18%) male patients; their mean age was 6.97 years (range 1.5 to 12 years). In all patients, the diagnosis of MCT was made from initial elevated levels of iCT after stimulation with pentagastrin. Three patients had clinical evidence of disease preoperatively. All patients underwent a total thyroidectomy and lymph nodes were removed from the central zone; a neck dissection was performed in the three with clinically obvious disease. MCT with C-cell hyperplasia was found in 11 children and C-cell hyperplasia alone in six. Of the 11 with carcinoma, eight had bilateral disease and three unilateral. Six children had bilateral C-cell hyperplasia. All 17 children were alive and feeling well at the time of this report; however, three had evidence of metastatic disease according to iCT measurements. None of the children had recurrent nerve injuries; one had evidence of hypoparathyroidism.(ABSTRACT TRUNCATED AT 250 WORDS)

    The article presents the results of a long-term research on development and clinical application of personalized cell therapy (PCT) for treatment of early postoperative (manifesting within the first 3 months after surgery) bullous keratopathy (BK). The method of intracameral PCT implies in vitro incubation of the patient's blood sample with poly(A:U) stimulator, separation of the serum with activated leukocytes, and injection of the final cell preparation into the anterior chamber. The fundamental part of the research was aimed at a detailed description of the cell preparation and investigation of its possible mechanisms of action. Cytokine and growth factor level in the cell preparation suggested that its high clinical efficacy might be due to its ability to improve regeneration of damaged corneal endothelium. The clinical study was conducted on a group of 52 patients with early BK. A significant effect (smoothing of the Descement's membrane folds, complete resorption of corneal edema, improvement of corneal transparency, reduction of corneal thickness and increase of visual acuity by 0.49 +/- 0.27) was achieved in 44.2% of patients, while partial effect was seen in 21.1% of patients. There was no clinical effect in 34.6% of patients. In those patients who developed significant or partial clinical effect after the PCT, many endotheliocytes appeared to have multiple nuclei (2 and more). In some patients polyploid nuclei persisted for 3-5 years after the treatment. Polyploidy results from incomplete mitosis which might be due to regenerative processes in the endothelium stimulated by the PCT. Obviously, high efficacy and relative simplicity of the method should promote its further clinical introduction.

    Beside varicose vein surgery, endovenous procedures (endovenous laser therapy, VNUS and foam sclerotherapy) are now therapeutic options with the following advantages: low invasiveness, only out-patient operations, quick resumption of general activities. Whether or not classical vein surgery today still fulfills patient demands was analysed by a study group of German vascular surgeons (ANG) as a multicentre patient questioning. The questionnaire was subdivided into eight main complexes with 24 questions about the early results of stripping operations (from start of preparation until suture removal) and the patients answers were analysed. Answers with points (1-6) and free answers were possible. Between 1.1.2005 and 31.3.2005 18 centres for vascular surgery collected 1708 questionnaires from patients after stripping operations. The complex "preparation and information about the operation" was scored with 1.33 to 1.39. The "general organisation" of the vascular centre was scored between 1.22 and 1.30. "Pain after operation" was rated at 1.98 (immediately), 2.26 (first day) and 2.12 (third day after operation). Reasons for other problems after surgery were haematoma (3.09), problems with the compression dressing (1.67), circulatory collapse (1.51), headache (1.33), nausea (1.25). The total score for all centres was 1.47. The early results after varicose vein surgery are good up to very good. The patients' reconvalescence time is short and there is a quick resumption of general activities. The invasiveness of vein surgery seems to be overestimated. Comparative studies to evaluate the new methods are necessary. Benchmarking projects like this study are essential parts of current quality control systems.

    The present study investigates Indonesian fourth-graders low performance in dealing with fractions in TIMSS 2015. Furthermore, the present study also explores possible reasons for this low performance. The data for this study was drawn from TIMSS 2015 data which included test results and responses to Teacher Questionnaire. Descriptive statistics was used to analyze the data. Indonesian textbooks were also analyzed to portrait a broader scope of possible reasons for students' low performance. The analysis of TIMSS test result reveals that Indonesian students, in comparison to students from other countries, had low understanding of the basic concepts of fractions. From the Teacher Questionnaire it was found that a possible reason for this low understanding was the Indonesian curriculum for third grade which gave low emphasis on the basic concepts of fractions and introduced operations of fractions rather early. Furthermore, the result of textbook analysis shows that Indonesian textbooks restricted only to one definition of fractions, i.e. fractions as parts of wholes. This finding might also explain Indonesian fourth graders' low understanding of fractions.

    Urine samples collected from residents of Bosnia and Herzegovina and Kosovo were analysed to determine their natural and depleted uranium content using MC-ICP-MS. All may have been exposed to depleted uranium released as a consequence of the deployment of armour-piercing rounds by the US Air Force. A 236 U tracer was employed to determine chemical recovery. Early results suggest that the levels of natural and depleted uranium excretion by the subjects, which ranged in age from 1 to 71 years, ranged from 2.8 - 58.2 ng d -1 and 1.3 - 46.3 ng d -1 , respectively. The results suggest accumulated body burdens of depleted uranium ranging from close to zero to 46 μg. All the body burdens predicted are lower than published values for the uranium content of the body (90μg) and health effects are not predicted. Further studies are underway to check the provenance of the results. (author)

    Background and Purpose: In early-stage Dupuytren's contracture, radiotherapy is applied to prevent disease progression. Long-term outcome and late toxicity of the treatment were evaluated in a retrospective analysis. Patients and Methods: Between 12/1982 and 02/2006, 135 patients (208 hands) were irradiated with orthovoltage (120 kV; 20 mA; 4-mm Al filter), in two courses with five daily fractions of 3.0 Gy to a total dose of 30 Gy; separated by a 6- to 8-week interval. The extent of disease was described according to a modified classification of Tubiana et al. Long-term outcome was analyzed at last follow-up between 02/2008 and 05/2008 with a median follow-up of 13 years (range, 2-25 years). Late treatment toxicity and objective reduction of symptoms as change in stage and numbers of nodules and cords were evaluated and used as evidence to assess treatment response. Results: According to the individual stages, 123 cases (59%) remained stable, 20 (10%) improved, and 65 (31%) progressed. In stage N 87% and in stage N/I 70% remained stable or even regressed. In more advanced stages, the rate of disease progression increased to 62% (stage I) or 86% (stage II). 66% of the patients showed a long-term relief of symptoms (i.e., burning sensations, itching and scratching, pressure and tension). Radiotherapy did not increase the complication rate after surgery in case of disease progression and only minor late toxicity (skin atrophy, dry desquamation) could be observed in 32% of the patients. There was no evidence for a second malignancy induced by radiotherapy. Conclusion: After a mean follow-up of 13 years radiotherapy is effective in prevention of disease progression and improves patients' symptoms in early-stage Dupuytren's contracture (stage N, N/I). In case of disease progression after radiotherapy, a ''salvage'' operation is still feasible. (orig.)

    We evaluated menopause-associated disorders and fertile life span in women with celiac disease (CD) under untreated conditions and after long-term treatment with a gluten-free diet. The participants were 33 women with CD after menopause (untreated CD group), 25 celiac women consuming a gluten-free diet at least 10 years before menopause (treated CD group), and 45 healthy volunteers (control group). The Menopause Rating Scale questionnaire was used to gather information on menopause-associated disorders. The International Physical Activity Questionnaire was used to acquire information on physical activity. Untreated celiac women had a shorter duration of fertile life span than did the control women because of an older age of menarche and a younger age of menopause (P menopause causes a shorter fertile period in untreated celiac women compared with control women. A gluten-free diet that started at least 10 years before menopause prolongs the fertile life span of celiac women. The perception of intensity of hot flushes and irritability is more severe in untreated celiac women than in controls. Low physical exercise and/or poorer quality of life frequently reported by untreated celiac women might be the cause of reduced discomfort tolerance, thus increasing the subjective perception of menopausal symptoms.

    Full Text Available Dysregulations in the brain serotonergic system and exposure to environmental stressors have been implicated in the development of major depressive disorder. Here, we investigate the interactions between the stress and serotonergic systems by characterizing the behavioral and biochemical effects of chronic stress applied during early-life or adulthood in wild type (WT mice and mice with deficient tryptophan hydroxylase 2 (TPH2 function. We showed that chronic mild stress applied in adulthood did not affect the behaviors and serotonin levels of WT and TPH2 knock-in (KI mice. Whereas, maternal separation (MS stress increased anxiety- and depressive-like behaviors of WT mice, with no detectable behavioral changes in TPH2 KI mice. Biochemically, we found that MS WT mice had reduced brain serotonin levels, which was attributed to increased expression of monoamine oxidase A (MAO A. The increased MAO A expression was detected in MS WT mice at 4 weeks old and adulthood. No change in TPH2 expression was detected. To determine whether a pharmacological stressor, dexamethasone (Dex, will result in similar biochemical results obtained from MS, we used an in vitro system, SH-SY5Y cells, and found that Dex treatment resulted in increased MAO A expression levels. We then treated WT mice with Dex for 5 days, either during postnatal days 7-11 or adulthood. Both groups of Dex treated WT mice had reduced basal corticosterone and glucocorticoid receptors expression levels. However, only Dex treatment during PND7-11 resulted in reduced serotonin levels and increased MAO A expression. Just as with MS WT mice, TPH2 expression in PND7-11 Dex-treated WT mice was unaffected. Taken together, our findings suggest that both environmental and pharmacological stressors affect the expression of MAO A, and not TPH2, when applied during the critical postnatal period. This leads to long-lasting perturbations in the serotonergic system, and results in anxiety- and depressive

    Redox imbalance is believed to contribute to the development and progression of several neurodegenerative disorders. Our aim was to develop an animal model that exhibits neuron-specific oxidative stress in the CNS to study the consequences and eventually find clues regarding the pathomechanisms of oxidative insults in neuronal homeostasis. We therefore generated a novel neuron-specific superoxide dismutase 2 (SOD2)-deficient mouse by deleting exon 3 of the SOD2 gene using CamKIIα promoter-driven Cre expression. These neuron-specific SOD2 knockout (SOD2(nko)) mice, although born at normal frequencies, died at the age of 4 weeks with critical growth retardation, severe energy failure, and several neurologic phenotypes. In addition, SOD2(nko) mice exhibited severe neuronal alterations such as reactive astrogliosis, neuronal cell cycle inhibition, and induction of apoptosis. JNK activation and stabilization of p53, as a result of reactive oxygen species accumulation, are most likely the inducers of neuronal apoptosis in SOD2(nko) mice. It is remarkable that hypothalamic regulation of glucose metabolism was affected, which in turn induced necrotic brain lesions in SOD2(nko) mice. Taken together, our findings suggest that exclusive deficiency of SOD2 in neurons results in an impaired central regulation of energy homeostasis that leads to persistent hypoglycemia, hypoglycemia-related neuropathology, and an early lethality of the mutant mice. © FASEB.

    Full Text Available Background. Fracture of the proximal 5th metatarsal bone (MTB reach almost 2% of all fractures of the foot. Conservative treatment is method of choice in almost all cases. Selected cases can benefit from acute surgery especially if the proximal fragment is severe displaced or the excessive articular step off is present.Materials and methods. In a 4 year period 14 patients were operated due to the acute fracture of proximal 5th MTB. All patients were treated in less than 2 weeks after the injury. 10 patients had base avulsion fracture in zone I and 4 had Jones fracture in zone II with dislocation of fragments? 5 mm, articular step off of 2 mm and 30% of articulation surface. We used tension bend wire in 9 cases (64%, partially threaded cancellous screw in 4 cases (28% and bone sutures in 1 case (7%. Postoperatively all patients used crutches with nonweight bearing for 4 weeks and afterwards partial weight bearing till the end of the treatment. All patients were practicing active exercises for ankle, foot and toes. The results were evaluated according to the Maryland Foot Score (MFS at least 20 months after injury.Results. 13 patients (93% were included in follow up. 12 patients were evaluated as excellent and only one as a good. All 13 patients have no or slight pain with no change in ADL or work ability. 9 patients (69% reached full functional result and 4 (31% patients had slight limitation during distance walk. Patients reached full weight bearing in average 7 weeks (5–13.Conclusions. Early operative treatment of selected cases allows fast return to preoperative activity without long term functional sequel. Both operative procedures, screw fixation and tension wire, yielded comparable and excellent end result.

    In rhesus macaques, previous studies have shown that episodic exposure to allergen alone or combined with ozone inhalation during the first 6 months of life results in a condition with many of the hallmarks of asthma. This exposure regimen results in altered development of the distal airways and parenchyma (Avdalovic et al., 2012). We hypothesized that the observed alterations in the lung parenchyma would be permanent following a long-term recovery in filtered air (FA) housing. Forty-eight infant rhesus macaques (30 days old) sensitized to house dust mite (HDM) were treated with two week cycles of FA, house dust mite allergen (HDMA), ozone (O 3 ) or HDMA/ozone (HDMA + O 3 ) for five months. At the end of the five months, six animals from each group were necropsied. The other six animals in each group were allowed to recover in FA for 30 more months at which time they were necropsied. Design-based stereology was used to estimate volumes of lung components, number of alveoli, size of alveoli, distribution of alveolar volumes, interalveolar capillary density. After 30 months of recovery, monkeys exposed to HDMA, in either group, had significantly more alveoli than filtered air. These alveoli also had higher capillary densities as compared with FA controls. These results indicate that early life exposure to HDMA alone or HDMA + O 3 alters the development process in the lung alveoli. - Highlights: • Abnormal lung development after postnatal exposure to ozone and allergen • This remodeling is shown as smaller, more numerous alveoli and narrower airways. • Allergen appears to have more of an effect than ozone during recovery. • These animals also have continued airway hyperresponsiveness (Moore et al. 2014)

    The primary goal of this study was to describe epidemiology and management strategies of the perforated duodenal ulcer, as well as the most common methods of laparoscopic perforated duodenal ulcer repair. The secondary goal was to demonstrate the value of prospective and retrospective studies regarding the early results of surgery and the risk factors. The tertiary goal was to emphasize the benefits of this operation, and the fourth goal was to clarify the possible risk factors associated with laparoscopic repair of the duodenal ulcer. The Medline/Pubmed database was used. Review was done after evaluation of 96 retrieved full-text articles. Thirteen prospective and twelve retrospective studies were selected, grouped, and summarized. The spectrum of the retrospective studies' results are as follows: median overall morbidity rate 10.5 %, median conversion rate 7%, median hospital stay 7 days, and median postoperative mortality rate 0%. The following is the spectrum of results of the prospective studies: median overall morbidity rate was slightly less (6%); the median conversion rate was higher (15%); the median hospital stay was shorter (5 days) and the postoperative mortality was higher (3%). The risk factors identified were the same. Shock, delayed presentation (> 24 hours), confounding medical condition, age > 70 years, poor laparoscopic expertise, ASA III-IV, and Boey score should be considered preoperative laparoscopic repair risk factors. Each of these factors independently should qualify as a criterion for open repair due to higher intraoperative risks as well as postoperative morbidity. Inadequate ulcer localization, large perforation size (defined by some as > 6 mm diameter, and by others as > 10 mm), and ulcers with friable edges are also considered as conversion risk factors.

    Synthesis results are presented for 12 elliptical and five lenticular galaxies which cover nearly a 6 mag range of absolute magnitude in the Fornax cluster (V = 1430 km s -1 ). The results of age, metallicity, and mass-to-light ratio (M/L) determinations are presented differentially as functions of galactic luminosity and morphology. Bright elliptical galaxies are well represented by main-sequence turnoff colors of (V-R)/sub c/roughly-equal0.37 and B-Vroughly-equal0.70, in good agreement with O'Connell's results for bright Virgo ellipticals. The relatively young main-sequence turnoff ages, of 6-10 Gyr for ellipticals of all luminosities, indicate that substantial star formation activity occurred in these galaxies for a period of 6dagger10 Gyr after the epoch of globular cluster formation. There is strong evidence for small amounts of current star formation in at least the brightest ellipticals of all luminosities, indicate that substantial star formation in at least the brightest ellipticals, variation in the amount of which may account for significant dispersion in the cluster U-V versus V color-magnitude relation. A metallicity gradient in [Fe/H] of at least 0.16 dex per absolute magnitude is derived, with the brightest ellipticals being 2 to 3 times more metal-rich than solar. The mean metallicities and turnoff ages of the faintest ellipticals are probably dependent on environment. Distance-independent upper limits to galaxy M/L ratios derived from the syntheses conform well with M/L ratios derived from velocity dispersion measurements and give no evidence for unseen mass in the nuclei of early type galaxies of any luminosity

    Full Text Available The forthcoming centenary of the Great War (1914-1918 can be considered an important occasion to focus attention on the subject of memorials for the fallen in the War. Immediately after the War, this topic was considered so relevant that in each municipality of Italy, Gardens and Avenues of Remembrance were realized and soon became places of memory, characterized by strong values of identity, history and landscape. In these places, usually correspondent to the number of fallen in that neighbourhood and located in urban or peripheral areas, nature and anthropic elements coexisted. For their importance, from 1926 these places have been included among the National Monuments. After the Second World War, avenues and gardens, as well as toponyms, were gradually forgotten and, in many cases, radically transformed. Due to a form of damnatio memoriae, which locations considered symbols of past governments have had to pay, these places have been changed, radically transforming also their authentic significance. A century on, it is important to start a programme for protection and enhancement of this historic heritage (classification at a regional and national scale, measurements, archival research, definition of guide lines for conservation. The essay also describes the early results of the classification of Gardens and Avenues of Remembrance in Abruzzo.

    Full Text Available Introduction: The epidermoid carcinoma of the upper aerodigestive tract is diagnosed in approximately 40% of the cases of advanced clinical stages. Objective: To evaluate the disease-free interval in patients with clinical stages I and II epidermoid carcinoma who were submitted to surgery or chemoradiation. Method: Retrospective study of the records of 139 patients treated for oropharyngeal epidermoid carcinoma submitted to treatment with curative intent. Among those patients, 38 were classified with early tumors clinical stages I and II. Twenty-seven (71.1% underwent surgical treatment whereas eleven (28.9% were treated with chemoradiation. The mean age was 56.4 years; 31 cases (81.6% were in men and seven (18.4% were in women. Results: Among the eleven patients who were submitted to chemoradiation, 72.7% obtained locoregional control of the disease and their disease-free survival was of 42%. Among the 27 patients operated, 19 remained in Clinical Stages I and II in the histological report and six underwent postoperative radiation therapy. The disease-free interval for two years was of 70%. Conclusion: The patients submitted to the surgery had a better disease-free interval as compared to those submitted to chemoradiation treatment.

    Objective Several types of nasal packs are used postoperatively in septoplasty. In this study, we compared two commonly used nasal packing materials, the intranasal septal splint with airway and Merocel tampon, in terms of pain, bleeding, nasal obstruction, eating difficulties, discomfort in sleep, and pain and bleeding during removal of packing in the early period. Methods The study group included 60 patients undergoing septoplasty. Patients were divided into two groups (n=30 in each group). An intranasal splint with airway was used for the patients in the first group after septoplasty, while Merocel nasal packing was used for the second group. Patients were investigated in terms of seven different factors - pain, bleeding while the tampon was in place, nasal obstruction, eating difficulties, night sleep, pain during removal of the nasal packing, and bleeding after removal of packing. Results There was no statistically significant difference between the groups in terms of pain 24 hours after operation (p=0.05), while visual analog scale (VAS) scores for nasal obstruction, night sleep, eating difficulties, and pain during packing removal were lower in the nasal splint group with a statistically significant difference (p<0.05). There was no statistically significant difference between the groups in terms of postoperative bleeding (p=0.23). Significantly less bleeding occurred during removal of the packing in the nasal splint group (p<0.05). Conclusion Our study indicates that the nasal splint was more comfortable and effective in terms of causing lesser bleeding and pain during removal of packing. PMID:29392071

    To review clinical and structural outcomes of ocriplasmin for treatment of stage 2 macular holes. A retrospective review of the first patients with stage 2 macular holes to be treated with ocriplasmin at Massachusetts Eye and Ear Infirmary. All patients were imaged with spectral-domain optical coherence tomography (SD-OCT). Eight patients with stage 2 macular holes received a single injection of 125 μg of ocriplasmin. One patient (12.5%) demonstrated macular hole closure. The posterior hyaloid separated from the macula in six eyes (75%). All seven holes that remained open showed enlargement in hole diameters (narrowest, apical, and basal) at 1 week and 1 month. All seven were successfully closed with surgery. Ellipsoid zone disruptions were observed by OCT in four eyes (50%) and persisted throughout follow-up (more than 6 months on average). In early clinical results, the authors found a lower macular hole closure rate with ocriplasmin than previously reported. Enlargement was observed in all holes that failed to close with ocriplasmin. The authors found ellipsoid zone disruptions that persisted through 6 months of follow-up after ocriplasmin injection. Further work is needed to investigate the cause for these ellipsoid zone changes. Copyright 2014, SLACK Incorporated.

    This nonrandomized feasibility study was designed to provide a preliminary assessment of the impact of a narrative and vocabulary instruction program provided by a speech-language pathologist (SLP) in a regular classroom setting. Forty-three children attending 2 first-grade classrooms participated in the study. Children in each classroom were divided into high- and low-risk subgroups on the basis of their performance on a narrative test. Narrative and vocabulary instruction was provided by an SLP in 1 classroom for three 30-min periods per week for 6 weeks. The children in the experimental classroom made clinically significant improvements on narrative and vocabulary measures; children in the comparison classroom did not. Within the experimental classroom, children in the high-risk subgroup demonstrated greater gains in narration and fewer gains in vocabulary than children in the low-risk subgroup. There were no subgroup differences in the comparison classroom. These preliminary results provide early evidence of the feasibility of implementing a narrative instruction program in a classroom setting. Children at a high risk for language difficulties appeared to profit more from the narrative instruction than from the embedded vocabulary instruction. More extensive research on this instructional program is warranted.

    Retrieval of removable inferior vena cava (IVC) filters in selected patients is widely practiced. The purpose of this multicenter study was to evaluate the feasibility and results of percutaneous removal of the ALN removable filter in a large patient cohort. Between November 2003 and June 2006, 123 consecutive patients were referred for percutaneous extraction of the ALN filter at three centers. The ALN filter is a removable filter that can be implanted through a femoral/jugular vein approach and extracted by the jugular vein approach. Filter removal was attempted after an implantation period of 93 ± 15 days (range, 6-722 days) through the right internal jugular vein approach using the dedicated extraction kit after control inferior vena cavography. Following filter removal, vena cavograms were obtained in all patients. Successful extraction was achieved in all but one case. Among these successful retrievals, additional manipulation using a femoral approach was needed when the apex of the filter was close to the IVC wall in two patients. No immediate IVC complications were observed according to the postimplantation cavography. Neither technical nor clinical differences between early and late filter retrieval were noticed. Our data confirm the safety of ALN filter retrieval up to 722 days after implantation. In infrequent cases, additional endovenous filter manipulation is needed to facilitate extraction.

    We report on early results from a pilot program searching for metal-poor stars with LAMOST and follow-up high-resolution observation acquired with the MIKE spectrograph attached to the Magellan II telescope. We performed detailed abundance analysis for eight objects with iron abundances [Fe/H] < -2.0, including five extremely metal-poor (EMP; [Fe/H] < -3.0) stars with two having [Fe/H] < -3.5. Among these objects, three are newly discovered EMP stars, one of which is confirmed for the first time with high-resolution spectral observations. Three program stars are regarded as carbon-enhanced metal-poor (CEMP) stars, including two stars with no enhancement in their neutron-capture elements, which thus possibly belong to the class of CEMP-no stars; one of these objects also exhibits significant enhancement in nitrogen, and is thus a potential carbon and nitrogen-enhanced metal-poor star. The [X/Fe] ratios of the sample stars generally agree with those reported in the literature for other metal-poor stars in the same [Fe/H] range. We also compared the abundance patterns of individual program stars with the average abundance pattern of metal-poor stars and find only one chemically peculiar object with abundances of at least two elements (other than C and N) showing deviations larger than 0.5 dex. The distribution of [Sr/Ba] versus [Ba/H] agrees that an additional nucleosynthesis mechanism is needed aside from a single r-process. Two program stars with extremely low abundances of Sr and Ba support the prospect that both main and weak r-processes may have operated during the early phase of Galactic chemical evolution. The distribution of [C/N] shows that there are two groups of carbon-normal giants with different degrees of mixing. However, it is difficult to explain the observed behavior of the [C/N] of the nitrogen-enhanced unevolved stars based on current data

    Simian Virus 40 (SV40) early transcription is repressed when the product of early transcription, T-antigen, binds to its cognate regulatory sequence, Site I, in the promoter of the SV40 minichromosome. Because SV40 minichromosomes undergo replication and transcription potentially repression could occur during active transcription or during DNA replication. Since repression is frequently epigenetically marked by the introduction of specific forms of methylated histone H3, we characterized th...

    Purpose: To evaluate the cosmetic outcome of patients treated with wide local excision and intraoperative radiotherapy for early-stage breast cancer. Methods and Materials: A total of 50 women were treated on a pilot study to evaluate the feasibility of intraoperative radiotherapy at wide local excision. The eligibility criteria included age >60, tumor size ≤2.0 cm, clinically negative lymph nodes, and biopsy-established diagnosis. After wide local excision, a custom breast applicator was placed in the excision cavity, and a dose of 20 Gy was prescribed to a depth of 1 cm. After 18 patients were treated, the dose was constrained laterally to 18 Gy. The cosmetic outcome was evaluated by photographs at baseline and at 6 and 12 months postoperatively. Four examiners graded the photographs for symmetry, edema, discoloration, contour, and scarring. The grades were evaluated in relationship to the volume of irradiated tissue, tumor location, and dose at the lateral aspects of the cavity. Results: The median volume of tissue receiving 100% of the prescription dose was 47 cm 3 (range, 20-97 cm 3 ). Patients with ≤47 cm 3 of treated tissue had better cosmetic outcomes than did the women who had >47 cm 3 of treated tissue. Women who had received 18 Gy at the lateral aspects of their cavities had better cosmetic outcomes than did women who had received 20 Gy at the lateral aspects. When comparing the 6- and 12-month results, the scores remained stable for 63%, improved for 17%, and worsened for 20%. Conclusion: Intraoperative radiotherapy appears feasible for selected patients. A favorable cosmetic outcome appears to be related to a smaller treatment volume. The cosmetic outcome is acceptable, although additional follow-up is necessary

    Full Text Available Background: Growing rod systems have been used in the last 30 years for the treatment of early onset scoliosis (EOS with variable success rates. We report the results of treatment of EOS with a newly developed hybrid rod distraction system applied to the rib cage and spine with a nonfusion technique in a prospective multicenter clinical trial. Materials and Methods: A total of 22 patients affected by progressive EOS resistant to cast and/or brace treatment were enrolled from 2004 to 2005 after informed consent into a trial of surgical treatment with a single spine-to-rib growing rod instrumentation growing spine profiler (GSP. Curves> 60° Cobb in the frontal plane or bending < 50% were addressed with staged anterior annulotomy and fusion and posterior implantation of a GSP rod. Less severe and rigid curves were treated with posterior implantation of GSP only. The elongation of GSP was planned according to spinal growth. Patients were kept in a brace between elongations. Results: A total of 20 patients were available to follow-up with complete data. The mean follow up is 4.1 years. Mean age at time of initial surgery was 5 years (3-8. Nine patients had staged antero-posterior surgeries, 11 posterior only surgeries. Mean spinal growth was 1.9 cm (1.5-2.3 or 0.5 cm per year. Mean coronal Cobb′s angle correction was from 56° to 45°. Major complications affected 40% of patients and included rod failure in 6/20 and crankshaft in 5/20 (all in the anteroposterior surgery group. Conclusion: Treatment of EOS with spine-to-rib growing rod in the present form provides similar correction and complication rates to those published in the series considering traditional single or dual growing rod systems. Based on this, the authors recommend revision of the GSP design and a new clinical trial to test safety and efficacy.

    The aims and objectives of this study were placement of implants in freshly extracted sockets of anterior teeth and to evaluate the implant stability, peri-implant radiolucency and gingival inflammation around implant over a short period of 30 months. A total of 12 patients (8 male and 4 female), ranging in the age from 20 to 50 years, from March 2007 to June 2007, were evaluated for immediate implant placement into 22 fresh extraction sockets. Only maxillary and mandibular anterior teeth/roots (central incisors, lateral incisors and canines) were considered for replacement with implants. One piece implant with integrated abutment and integrated surface, non-submerged, threaded and tapered at apical 5 mm, sand-blasted and acid etched surfaced implants (HI-TEC TRX-OP Implants of Life Care Company) were used. The mobility was not present in any of the implants at all the follow up visits. There were 2 implants at 6 month, 1 implant at 12 month, 1 implant at 18 month visits, showing peri-implant radiolucency at some sites at bone to implant contact site. Severe gingival inflammation was not observed in any of the implant site. At every follow-up visit, every implant met the criteria of success and none was found to be failed over a 30 months duration i.e. 100% success rate was achieved by implants in immediate extraction socket. The success rate of implant survival in this study was found 100%. These implants have fulfilled all the criteria of implant success and based on the defined criteria, the success rate of implants placed in immediate extraction sockets of anterior teeth compared favorably with the conventional implants. The early results of the present study showed that high survival rates with the implants in immediate extraction sockets can be achieved.

    Full Text Available Background: Hip replacement following failed internal fixation (dynamic hip screw for intertrochanteric fractures or previous hip arthroplasty presents a major surgical challenge. Proximal fitting revision stems do not achieve adequate fixation. Distal fixation with long-stemmed extensively coated cementless implants (like the Solution™ system affords a suitable solution. We present our early results of 15 patients treated with extensively coated cementless revision stems. Materials and Methods: Fifteen patients with severely compromised proximal femora following either failed hip arthroplasty or failed internal fixation (dynamic hip screw fixation for intertrochanteric fractures were operated by the senior author over a two-year period. Eight patients had aseptic loosening of their femoral stems following cemented hip replacements, with severe thinning of their proximal cortices and impending stress fractures. Seven had secondary hip arthritis following failure of long implants for comminuted intertrochanteric or subtrochanteric femoral fractures. All patients were treated by removal of implant (cemented stems/DHS implants and insertion of long-stemmed extensively coated cementless revision (′ Solution™; DePuy, Warsaw (IN, US′ stems along with press-fit acetabular component (Duraloc Cup, DePuy, Warsaw (IN, US. All eight hip revisions needed extended trochanteric osteotomies. Results: All patients were primarily kept in bed on physiotherapy for six weeks and then gradually progressed to weight-bearing walking over the next six to eight weeks. The Harris Hip Scores and patient satisfaction were used for final evaluation. We achieved good results in the short term studied. In our first three patients (all following failed cemented total hip replacements, we resorted to cerclage wiring to hold osteotomised segments (done to facilitate stem removal. The subsequent 12 proceeded without the need for cerclage wiring. One patient had a

    Uncertainty and sensitivity analysis techniques based on Latin hypercube sampling, partial correlation analysis and stepwise regression analysis are used in an investigation with the MACCS model of the early health effects associated with a severe accident at a nuclear power station. The primary purpose of this study is to provide guidance on the variables to be considered in future review work to reduce the uncertainty in the important variables used in the calculation of reactor accident consequences. The effects of 34 imprecisely known input variables on the following reactor accident consequences are studied: number of early fatalities, number of cases of prodromal vomiting, population dose within 10 mi of the reactor, population dose within 1000 mi of the reactor, individual early fatality probability within 1 mi of the reactor, and maximum early fatality distance. When the predicted variables are considered collectively, the following input variables were found to be the dominant contributors to uncertainty: scaling factor for horizontal dispersion, dry deposition velocity, inhalation protection factor for nonevacuees, groundshine shielding factor for nonevacuees, early fatality hazard function alpha value for bone marrow exposure, and scaling factor for vertical dispersion

    The Xpert MTB/RIF assay has garnered significant interest as a sensitive and rapid diagnostic tool to improve detection of sensitive and drug resistant tuberculosis. However, most existing literature has described the performance of MTB/RIF testing only in study conditions; little information is available on its use in routine case finding. TB REACH is a multi-country initiative focusing on innovative ways to improve case notification. We selected a convenience sample of nine TB REACH projects for inclusion to cover a range of implementers, regions and approaches. Standard quarterly reports and machine data from the first 12 months of MTB/RIF implementation in each project were utilized to analyze patient yields, rifampicin resistance, and failed tests. Data was collected from September 2011 to March 2013. A questionnaire was implemented and semi-structured interviews with project staff were conducted to gather information on user experiences and challenges. All projects used MTB/RIF testing for people with suspected TB, as opposed to testing for drug resistance among already diagnosed patients. The projects placed 65 machines (196 modules) in a variety of facilities and employed numerous case-finding strategies and testing algorithms. The projects consumed 47,973 MTB/RIF tests. Of valid tests, 7,195 (16.8%) were positive for MTB. A total of 982 rifampicin resistant results were found (13.6% of positive tests). Of all tests conducted, 10.6% failed. The need for continuous power supply was noted by all projects and most used locally procured solutions. There was considerable heterogeneity in how results were reported and recorded, reflecting the lack of standardized guidance in some countries. The findings of this study begin to fill the gaps among guidelines, research findings, and real-world implementation of MTB/RIF testing. Testing with Xpert MTB/RIF detected a large number of people with TB that routine services failed to detect. The study demonstrates the

    Elbow flexion posture, caused by spasticity of the muscles on the anterior surface of the elbow, is the most common elbow deformity seen in patients with cerebral palsy. This study retrospectively evaluated early results of 2 surgical interventions for elbow flexion deformities based on degree of contracture. We hypothesized that by guiding surgical treatment to degree of preoperative contracture, elbow extension and flexion posture angle at ambulation could be improved while preserving maximum flexion. Eighty-six patients (90 elbows) were treated for elbow spasticity due to cerebral palsy. Seventy-one patients (74 elbows) were available for follow-up. Fifty-seven patients with fixed elbow contractures less than 45° were surgically treated with a partial elbow muscle lengthening, which included partial lengthening of the biceps and brachialis and proximal release of the brachioradialis. Fourteen patients (17 elbows) with fixed elbow contractures ≥ 45° had a more extensive full elbow release, with biceps z-lengthening, partial brachialis myotomy, and brachioradialis proximal release. Age at surgery averaged 10 years (range, 3-20 y) for partial lengthening and 14 years (range, 5-20 y) for full elbow release. Follow-up averaged 22 months (range, 7-144 mo) for partial lengthening and 18 months (range, 6-51 mo) for full elbow release. Both groups achieved meaningful improvement in flexion posture angle at ambulation, active and passive extension, and total range of motion. Elbow flexion posture angle at ambulation improved by 57° and active extension increased 17° in the partial lengthening group, with a 4° loss of active flexion. In the full elbow release group, elbow flexion posture angle at ambulation improved 51° and active extension improved 38°, with a loss of 19° of active flexion. Surgical treatment of spastic elbow flexion in cerebral palsy can improve deformity. We obtained excellent results by guiding the surgical intervention by the amount of

    Full Text Available Aim: The author reports early post-operative outcome and preliminary experience with an alternative form of treatment of cervical degenerative or spondylotic disease leading to spinal canal stenosis that involves fixation-arthrodesis of the affected spinal segment using one or two (double insurance transarticular screws for each joint. Materials and Methods: During the period of months from March 2013 to July 2013, six patients having cervical spondylotic cord compression were treated with transarticular method of screw fixation of the involved segments. The operation involved section of the spinous process at its base, opening up of the facet joint, denuding of articular cartilage, placement of intraarticular cavity bone graft chips and insertion of either a single or two transarticular screws at each level. The fixation was done in four levels in four patients and at two levels in two patients. Japanese Orthopedic Association score, visual analog scale (neck pain and Odom′s criteria were used to monitor the clinical status of the patients before and after the surgery and at follow-up. Results: Immediate post-operative and a relatively short-term post-operative outcome was remarkably gratifying. During the average period of follow-up of 6 months (range: 3-8 months; there was varying degree of recovery of symptoms. The procedure resulted in firm stabilization and fixation of the spinal segment and provided a ground for arthrodesis. No patient worsened after treatment. During the period of follow-up, all patients showed remarkable and progressive recovery in symptoms. Conclusions: Vertical instability and telescoping, listhesis or overriding of the facets on physical activity seems to be the defining phenomenon in pathogenesis of cervical spondylotic disease. The clinical outcome in our patients suggest that only fixation of the spinal segment can be a rationale form of treatment. Transarticular method of treatment is a simple, safe and

    Estrogen is critical for bone formation and growth in women. Estrogen exposures occur throughout life, including prenatally, and change with reproductive events, such as menarche and menopause. The objective of this study was to investigate the association between age at menarche, age at menopause, and years of menstruation with incidence of osteoporosis and assess the impact of prenatal exposure to diethylstilbestrol (DES), a synthetic estrogen, on such associations. Participants were 5573 women in the National Cancer Institute Combined Cohort Study of DES (1994-2006). Data on reproductive history and medical conditions were collected through questionnaires at baseline in 1994 and subsequently in 1997, 2001, and 2006. Age-stratified Cox regression models were used to calculate multivariable incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Effect measure modification by prenatal DES exposure was assessed using cubic restricted spline regression models. Osteoporosis was the main outcome measure. The IRRs for osteoporosis incidence with age at menarche less than 11 years and age at menopause of 50 years or younger were 0.82 (CI 0.59, 1.14) and 0.61 (CI 0.40, 0.92), respectively. Fewer than 25 years of menstruation was associated with an increased incidence of osteoporosis (IRR 1.80; CI 1.14, 2.86) compared with 35 years or more of menstruation. Associations were stronger among women who had not been prenatally exposed to DES. Our data support the hypothesis that lifetime cumulative exposure to estrogens is protective against osteoporosis. Furthermore, prenatal exposure to estrogen appears to modify these associations, although the mechanism by which this occurs is unknown.

    To evaluate management of early-onset intrauterine growth restriction (IUGR) and to define outcome according to obstetric setting. During an 11-year period (2000-2011), data of patients presenting with IUGR and preterm delivery of less than 30 weeks of gestation at a tertiary perinatal center were retrospectively reviewed. A total of 92 pregnancies were investigated. Delivery was indicated for fetal reasons in 38 out of 92 patients. Sixteen children of our cohort died within one year post partum, out of which eight had suffered from severe early-onset IUGR causing iatrogenic preterm delivery. Concerning the fetal outcome, gestational age at delivery and antenatal exposure to corticosteroids were found to be crucial. In some cases, respiratory distress syndrome prophylaxis and a "wait and see" approach to management in favor of a prolongation of the pregnancy might be favorable. Randomized prospective trials in early-onset IUGR with threatened preterm deliveries are needed in order to define guidelines for an individually tailored management of early-onset preterm infants.

    ObjectiveTo summarize our early experience gained from the chimney technique for type B aortic dissection (TBAD) extending to the aortic arch and to evaluate the aortic remodeling in the follow-up period.MethodsFrom September 2011 to July 2014, 27 consecutive TBAD patients without adequate proximal landing zones were retrograde analyzed. Chimney stent-grafts were deployed parallel to the main endografts to reserve flow to branch vessels while extending the landing zones. In the follow-up period, aortic remodeling was observed with computed tomography angiography.ResultsThe technical success rate was 100 %, and endografts were deployed in zone 0 (n = 3, 11.1 %), zone 1 (n = 18, 66.7 %), and zone 2 (n = 6, 22.2 %). Immediately, proximal endoleaks were detected in 5 patients (18.5 %). During a mean follow-up period of 17.6 months, computed tomography angiography showed all the aortic stent-grafts and chimney grafts to be patent. Favorable remodeling was observed at the level of maximum descending aorta and left subclavian artery with expansion of true lumen (from 18.4 ± 4.8 to 25 ± 0.86 mm, p < 0.001 and 27.1 ± 0.62 to 28.5 ± 0.37 mm, p < 0.001) and depressurization of false lumen (from 23.7 ± 2.7 to 8.7 ± 3.8 mm, p < 0.001, from 5.3 ± 1.2 to 2.1 ± 2.1 mm, p < 0.001). While at the level of maximum abdominal aorta, suboptimal remodeling of the total aorta (from 24.1 ± 0.4 to 23.6 ± 1.5 mm, p = 0.06) and true lumen (from 13.8 ± 0.6 to 14.5 ± 0.4 mm, p = 0.08) was observed.ConclusionBased on our limited experience, the chimney technique with thoracic endovascular repair is demonstrated to be promising for TBAD extending to the arch with favorable aortic remodeling.

    Full Text Available Background: Compound odontomas in the anterior maxilla during mixed dentition frequently cause obstruction to the eruption pathway of permanent upper anterior teeth. Removal of the odontomas may or may not lead to spontaneous eruption of the impacted teeth depending on the age when the surgery is performed, the size of the lesion, and the stage of tooth development of the involved teeth. Purpose: This paper attempts to emphasize the importance of early removal of compound odontoma to enable spontaneous eruption of the affected teeth. Case: A case of odontoma in the anterior maxilla causing failure of eruption and delayed root formation of upper right permanent lateral incisor and canine in a 10-year-old male patient is presented. Case management: The odontoma was surgically removed under general anesthesia and histology result confirmed the diagnosis of compound odontoma. A three-year post surgical follow up showed spontaneous eruption as well as continued root formation of the two affected teeth. Conclusion: Removal of odontoma may lead to spontaneous eruption of the affected teeth if their root development are not completed.Latar belakang: Compound odontoma pada daerah anterior maksila pada masa geligi pergantian sering menyebabkan hambatan erupsi pada gigi permanen penggantinya.

    We report our early experience of 20 cases of metal on metal articulation total hip arthroplasty in 19 young patients. Avascular necrosis of the femoral head (63%) was the commonest diagnosis for patients undergoing this procedure, followed by osteoarthritis (21%). In general, most of the patients were young and physically active with an average age of 43.1 years (range, 25 to 58 years). The average follow-up period was 18 months (range, 7 to 46 months). The mean total Harris Hip Score preoperatively and at final follow-up was 31 points and 89 points respectively. The mean total Pain Score improved from an average of 11.5 to 41.1 points at final follow-up. Sixteen (84%) of the patients had a good to excellent hip score. There was one dislocation, which stabilized after reduction and conservative management. One case of early infection underwent a two-staged revision.

    The conceptual design of one of the potential early commercial MHD power plants was studied. The plant employs oxygen enrichment of the combustion air and preheating of this oxygen enriched air to an intermediate temperature of 1200 F attainable with a tubular type recuperative heat exchanger. Conceptual designs of plant componets and equipment with performance, operational characteristics, and costs are reported. Plant economics and overall performance including full and part load operation are reviewed. The projected performance and estimated cost of this early MHD plant are compared to conventional power plants, although it does not offer the same high efficiency and low costs as the mature MHD power plant. Environmental aspects and the methods incorporated in plant design for emission control of sulfur and nitrogen are reviewed.

    We performed a prospective study to evaluate the value of contrast-enhanced ultrasound (CEUS) in quantitative evaluation of renal cortex perfusion in patients suspected of early diabetic nephropathies (DN), with the estimated GFR (MDRD equation) as the gold standard. The study protocol was approved by the hospital review board; each patient gave written informed consent. Our study included 46 cases (21 males and 25 females, mean age 55.6 ± 4.14 years) of clinical confirmed early DN patients. After intravenous bolus injection of 1 ml sulfur hexafluoride microbubbles of ultrasound contrast agent, real time CEUS of renal cortex was performed successively using a 2-5 MHz convex probe. Time-intensity curves (TICs) and quantitative indexes were created with Qlab software. Receiver operating characteristic (ROC) curves were used to predict the diagnostic criteria of CEUS quantitative indexes, and their diagnostic efficiencies were compared with resistance index (RI) and peak systolic velocity (PSV) of renal segmental arteries by chi square test. Our control group included forty-five healthy volunteers. Difference was considered statistically significant with P  0.05). CEUS might be helpful to improve early diagnosis of DN by quantitative analyses. AUC and DPI might be valuable quantitative indexes.

    Controversy persists surrounding early management of disorders of sex development. We assessed genital appearance, gender identity, and quality of life in prepubertal children who have had early surgical intervention. Children treated for disorders of sex development who were 5 to 10 years of age were eligible (n = 54). Children were scored (modified Creighton scale) for anatomical and cosmetic outcome, and both patients and parents completed PedsQL quality-of-life and gender identity questionnaires, with ethics approval. Of 54 patients, 41 presented for review. Treatment began at 13.2 (1.8-250.1) months (median; range) and were reviewed at 7.5 +/- 2.1 (mean +/- SD) years of age. Nineteen were raised as girls and 22 as boys. Girls had good (85%) or satisfactory (15%) anatomical/cosmetic outcome, whereas 52% boys had good, 38% satisfactory, and 10% poor cosmetic outcomes. On gender identity questionnaire, boys scored 3.9 +/- 0.4 (mean +/- SD) and girls 3.6 +/- 0.5; 1 of 19 boys and 3 of 19 girls had lower scores, suggesting risk of gender identity disorder. Quality-of-life scores were 80+ for physical and 65 to 80 for psychosocial scores. Early intervention is generally associated with positive outcomes for patients and parents. Girls had better anatomical outcomes than boys, and gender dysphoria risks were low in both sexes.

  6. Attitudes of the German general population toward early diagnosis of dementia--results of a representative telephone survey.

    Tobias Luck

    Full Text Available BACKGROUND: Early detection of dementia has clearly improved. Even though none of the currently available treatments for the most common form of dementia, Alzheimer's dementia, promises a cure, early diagnosis provides several benefits for patients, caregivers, and health care systems. This study aimed to describe attitudes toward early diagnosis of dementia in the German general population. METHODS: A representative telephone survey of the German population aged 18+ years (n = 1,002 was conducted in 2011. RESULTS: The majority of respondents (69% would be willing to be examined for early diagnosis of dementia. Almost two thirds reported that they would prefer their general practitioner (GP as the first source of professional help. More than half of the respondents (55% stated their belief that dementia could be prevented. Respondents mostly indicated psychosocial prevention options. CONCLUSIONS: Our findings suggest that the general population in Germany is very open to early diagnosis of dementia; however, this seems connected with large expectations on the effectiveness of prevention options. Dementia awareness campaigns may be employed to carefully inform the public about the prevention options currently available and their efficacy. To exploit GPs' potential as a gatekeeper for early detection of dementia, their ability to identify patients with antecedent and mild stages of the disease must be improved.

    The Mars Science Laboratory rover, Curiosity, landed at Gale Crater on August 5th (PDT) and initiated an investigation of modern and ancient environments. The 155-km diameter Gale Crater was chosen as Curiosity's field site based on several attributes: the interior Mount Sharp preserves a succession of flat-lying strata extending almost 5 km above the elevation of the landing site; the lower few hundred meters of the mound show a progression with relative age from clay-bearing to sulfate-bearing strata, separated by an unconformity from overlying likely anhydrous strata; the landing ellipse is characterized by a mixture of alluvial fan and high thermal inertia/high albedo stratified deposits; and a number of stratigraphically/geomorphically distinct fluvial features. Gale's regional context and strong evidence for a progression through multiple potentially habitable environments, represented by a stratigraphic record of extraordinary extent, ensure preservation of a rich record of the environmental history of early Mars. Curiosity has an expected lifetime of at least one Mars year (~23 months), and drive capability of at least 20 km. The MSL science payload was specifically assembled to assess habitability and includes a gas chromatograph-mass spectrometer and gas analyzer that will search for organic carbon in rocks, regolith fines, and the atmosphere (SAM); an x-ray diffractometer that will determine mineralogical diversity (CheMin); focusable cameras that can image landscapes and rock/regolith textures in natural color (MAHLI, Mastcam); an alpha-particle x-ray spectrometer for in situ determination of rock and soil chemistry (APXS); a laser-induced breakdown spectrometer to remotely sense the chemical composition of rocks and minerals (ChemCam); an active/passive neutron spectrometer designed to search for water in rocks/regolith (DAN); a weather station to measure modern-day environmental variables (REMS); and a sensor designed for continuous monitoring of

    Menstruation is a significant part of women's lives. It has been studied from many perspectives to draw various conclusions about biological and physiological development, gender differences, and sociocultural environments. The purpose of this study was to explore how male and female pubescent students perceive and interpret menarche and menstruation and how their perceptions reflect gender differences and the sociocultural environment in eastern Taiwan. This was an exploratory qualitative study that employed focus group interviews. Data were collected from 20 girls and 27 boys, aged 10-12 years, who were recruited from two elementary schools. Participants engaged in 19 focus group discussions, which lasted 45-60 minutes each. Discussion transcripts were collected, encoded, categorized, and analyzed using the Atlas V 5.0 software. The central theme in menarche and menstruation experiences among pubescent students in eastern Taiwan can be summarized as, "Struggling to grow up amidst contradictions," an attitude that reflects gender divisions and sociocultural representations and practices. Generally, participants' views on menstruation fell within five subthemes: "Ambiguous," "Disregarded," "Dirty," "Personal," and "Transitional." These themes were analyzed within the contexts of society, school, and family. In line with previous research, this study shows the need for more individual reproductive health consultations, reliable sex education, and well-planned health policies to assist pubescent students manage menstruation. In addition, this study suggests that the subjugation of girls and women remains a critical issue that must be addressed and challenged.

    Lipid rafts are the preferential site of numerous membrane signaling proteins which are involved in neuronal functioning and survival. These proteins are organized in multiprotein complexes, or signalosomes, in close contact with lipid classes particularly represented in lipid rafts (i.e. cholesterol, sphingolipids and saturated fatty acids), which may contribute to physiological responses leading to neuroprotection. Increasing evidence indicates that alteration of lipid composition in raft structures as a consequence of neuropathologies, such as Alzheimer's disease (AD) and Parkinson's disease (PD), causes a dramatic increase in lipid raft order. These phenomena may correlate with perturbation of signalosome activities, likely contributing to neurodegenerative progression. Interestingly, significant disruption of stable raft microenvironments has been already observed in the first stages of either AD or PD, suggesting that these alterations may represent early events in the neuropathological development. In this regard, the search for biochemical markers, such as specific metabolic products altered in the brain at the first steps of the disease, presently represents an important challenge for early diagnostic strategies. Alterations of these biomarkers may be reflected in either plasma or cerebrospinal fluid, thus representing a potential strategy to predict an accurate diagnosis. We propose that pathologically-linked lipid raft markers may be interesting candidates to be explored at this level, although it has not been studied so far to what extent alteration of different signalosome components may be reflected in peripheral fluids. In this mini-review, we will discuss on relevant aspects of lipid rafts that contribute to the modulation of neuropathological events related to AD and PD. An interesting hypothesis is that anomalies on raft biomarkers measured at peripheral fluids might mirror the lipid raft pathology observed in early stages of AD and PD. Copyright

    Full Text Available The surgical management of small renal masses has continued to evolve, particularly with the advent of the robotic partial nephrectomy (RPN. Recent studies at high volume institutions utilizing near infrared imaging with indocyanine green (ICG fluorescent dye to delineate renal tumor anatomy has generated interest among robotic surgeons for improving warm ischemia times and positive margin rate for RPN. To date, early studies suggest positive margin rate using ICG is comparable to traditional RPN, however this technology improves visualization of the renal vasculature allowing selective clamping or zero ischemia. The precise combination of fluorescent compound, dose, and optimal tumor anatomy for ICG RPN has yet to be elucidated.

    Experiments have been performed in the National Spherical Torus Experiment (NSTX) to inject high harmonic fast wave (HHFW) power early during the plasma current ramp-up in an attempt to reduce the current penetration rate to raise the central safety factor during the flattop phase of the discharge. To date, up to 2 MW of HHFW power has been coupled to deuterium plasmas as early as t = 50 ms using the slowest interstrap phasing of k|| approximately equals 14 m(superscript)-1 (nf = 24). Antenna-plasma gap scans have been performed and find that for small gaps (5-8 cm), electron heating is observed with relatively small density rises and modest reductions in current penetration rate. For somewhat larger gaps (10-12 cm), weak electron heating is observed but with a spontaneous density rise at the plasma edge similar to that observed in NSTX H-modes. In the larger gap configuration, EFIT code reconstructions (without MSE [motional Stark effect]) find that resistive flux consumption is reduced as much as 30%, the internal inductance is maintained below 0.6 at 1 MA into the flattop, q(0) is increased significantly, and the MHD stability character of the discharges is strongly modified

    The CMS Experiment is defining its Computing Model and is experimenting and testing the new distributed features offered by many Grid Projects. This report describes use by CMS of the early-deployed systems of LCG (LCG-0 and LCG-1). Most of the used features here discussed came from the EU implemented middleware, even if some of the tested capabilities were in common with the US developed middleware. This report describes the simulation of about 2 million of CMS detector events, which were generated as part of the official CMS Data Challenge 04 (Pre-Challenge-Production). The simulations were done on a CMS-dedicated testbed (CMS-LCG-0), where an ad-hoc modified version of the LCG-0 middleware was deployed and where the CMS Experiment had a complete control, and on the official early LCG delivered system (with the LCG-1 version). Modifications to the CMS simulation tools for events produc tion where studied and achieved, together with necessary adaptations of the middleware services. Bilateral feedback (betwee...

    It is common practice to keep those patients with lower extremity autografts immobile until post-operative day (POD) 5. There is however inherent risks associated with even short periods of immobility. As of now there are no randomized controlled trials looking at early ambulation of patients with lower extremity autografts in the burn community.The objective of this study was to show that patients who begin ambulation within 24 hours of lower extremity autografting will have no increased risk of graft failure than those patients who remain immobile until POD 5. Thirty-one subjects who received autografts to the lower extremity were randomized after surgery into either the early ambulation group (EAG;17 subjects) or the standard treatment group (STG;14 subjects). Those subjects randomized to the EAG began ambulating with physical therapy on POD 1. Subjects in the STG maintained bed rest until POD 5. There was no difference in the number of patients with graft loss in either the EAG or STG on POD 5, and during any of the follow-up visits. No subjects required regrafting. There was a significant difference in the mean minutes of ambulation, with the EAG ambulating longer than the STG (EAG 23.4 minutes [SD 12.03], STG 14.1 [SD 9.00], P=.0235) on POD 5. Burn patients with lower extremity autografts can safely ambulate on POD 1 without fear of graft failure compared with those patients that remain on bed rest for 5 days.

    During the installation of buffer and canister in a deposition hole a number of different problems can arise. The problems are mainly connected to water flow from fractures in the rock into the deposition hole. At some conditions it probably will be necessary to protect the installed buffer blocks with a special sheet made of rubber or plastic. This report deals with two processes that can occur and are possible to strongly influence the buffer during installation: 1. Erosion. Erosion of bentonite from the deposition hole up to the voids in the tunnel backfill. This process will continue until a tunnel plug have been built and the voids in the backfill are filled with water. 2. Heave. Early wetting of the pellets filling may cause a heave of the buffer blocks that will decrease the density of the buffer. An erosion model has been suggested /Sanden et al. 2008b/ which makes it possible to estimate the amount of eroded material for a certain water flow rate during a certain time. In order to verify the model and investigate how the buffer in a deposition hole behaves when exposed to a water flow, a number of different tests have been performed: - Test type 1. Simulation of water flow out from a deposition hole. The deposition hole was made of steel and had a radial scale of 1:4 and a height of 0.6 meter. The pellets slot was scaled 1:1. After filling the deposition hole with buffer blocks and pellets, a constant water flow was applied in a point at the bottom. The discharged water at the top was collected and the amount of eroded material determined. The displacement of the blocks and pellets surfaces was also measured during the test. - Test type 2. The influence of test length on the erosion rate was investigated by performing tests with Plexiglas tubes of different lengths (0.4 and 4 meter). The tubes were positioned vertically, filled with pellets and a point inflow was applied in the bottom. The discharged water was collected at the top and the amount of eroded

    consecutive patients with 43 total hip arthroplasties performed through an anterior muscle sparing minimally invasive approach. We found the early complication rates and radiographic outcomes comparable to those reported from arthroplasties performed via traditional approaches. Complications included dislocation (2%, femur fracture (2%, greater trochanteric fracture (12%, postoperative periprosthetic intertrochanteric fracture (2%, femoral nerve palsy (5%, hematoma (2%, and postoperative iliopsoas avulsion (2%. Radiographic analysis revealed average cup anteversion of 19.6°±6.6, average cup abduction angle of 48.4°±7, stem varus of 0.9°±2, and a mean leg length discrepancy of 0.7 mm. The anterior approach to the hip is an attractive alternative to the more traditional approaches. Acceptable component placement with comparable complication rates is possible using a muscle sparing technique which may lead to faster overall recovery.

    To realize the treatment policy for early stage oral cancer, a survey of 102 institutes in Japan was performed by questionnaire. A majority of the otolaryngologists preferred surgery for the treatment of T1N0 and T2N0 cases of oral cancer. The preferred method of treatment for the T1N0 cases was simple tumor resection and that for the T2N0 cases was extended tumor resection with plastic surgery, elective neck dissection and combined radio-and/or chemotherapy. A majority of the radiologists preferred brachytherapy for T1N0 and non-invasive T2N0 cases. For invasive cases of T2N0 oral cancer, radiologists preferred either surgical treatment or the combination of brachytherapy and external irradiation. (author)

    A total of 25 cases with early gastric carcinoma, of which 10 cases were followed by gastrectomy, were given a combined radiotherapy with 5-Fu, Ft 207 or MFC at Miyagi Seijinbyo Center. Histologic examinations of biopsy specimens revealed the disappearance of cancer cells in five (42%) of 12 cases and those of serial specimens of the resected stomach showed the complete disappearance of cancer cells in three (27%) of 11 lesions (10 cases). Five year survival rate in 15 non-resected cases was only 30%. From these results, it was suggested that a combined radiotherapy of early gastric carcinoma should not be chosen as a curative treatment procedure but it might be valuable, if early carcinoma was thought to be inoperable because of other medical reasons.

    In order to establish the most reliable marker for distinguishing urinary tract infections (UTI) with and without renal parenchymal involvement (RPI), we recorded the clinical features and admission leukocyte count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum procalcitonin (PCT) in 57 children (including 43 girls) aged 2-108 months admitted with a first episode of UTI. RPI was evaluated by Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy within 7 days of admission. To establish cut-off points for ESR, CRP, and PCT, we used receiver operating characteristics curves and compared the area under the curve for ESR, CRP, and PCT. Twenty-seven children were diagnosed as having RPI based on positive renal scintigraphy. A body temperature of >38 degrees C, a history of diarrhea, and poor oral intake were more common in patients with RPI. ESR, CRP, and PCT, but not leukocyte count, were significantly higher in patients with RPI (P UTI than ESR and CRP. Using a cut-off value of 0.85 ng/ml, PCT had the best performance, with sensitivity, specificity, and positive and negative predictive values of 89%, 97%, 96%, and 91% respectively. Serum PCT is a better marker than ESR, CRP, and leukocyte count for the early prediction of RPI in children with a first episode of UTI.

    The purpose is to report findings of a quality improvement (QI) project implemented at two hospital-based dental clinics that care for children with early childhood caries (ECC). We tested a disease management (DM) approach in children younger than age 60 months with ECC. After 30 months, for the 403 and 234 DM patients at Children's Hospital Boston (CHB) and Saint Joseph Hospital (SJH) who returned for at least two visits, rates of new cavitation, pain, and referrals to the OR were 26.1, 13.4 and 10.9% for CHB and 41.0, 7.3 and 14.9% for SJH. Rates of new cavitation, pain, and referrals to the OR for historical controls were 75.2, 21.7, and 20.9% for CHB and 71.3, 31.3, and 25.0% for SJH. A risk-based DM approach utilizing QI strategies to address ECC can be implemented into practice and has the potential to improve care and health outcomes.

    Spectral energy distributions (SEDs) and radio continuum spectra are presented for a northern sample of 104 extragalactic radio sources. based on the Planck Early Release Compact Source Catalogue (ERCSC) and simultaneous multi frequency data. The nine Planck frequencies, from 30 to 857 GHz, are complemented by a set of simultaneous observations ranging from radio to gamma-rays. This is the first extensive frequency coverage in the radio and millimetre domains for an essentially complete sample of extragalactic radio sources, and it shows how the individual shocks, each in their own phase of development, shape the radio spectra as they move in the relativistic jet. The SEDs presented in this paper were fitted with second and third degree polynomials to estimate the frequencies of the synchrotron and inverse Compton (IC) peaks, and the spectral indices of low and high frequency radio data, including the Planck ERCSC data, were calculated. SED modelling methods are discussed, with an emphasis on proper. physical modelling of the synchrotron bump using multiple components. Planck ERCSC data also suggest that the original accelerated electron energy spectrum could be much harder than commonly thought, with power-law index around 1.5 instead of the canonical 2.5. The implications of this are discussed for the acceleration mechanisms effective in blazar shock. Furthermore in many cases the Planck data indicate that gamma-ray emission must originate in the same shocks that produce the radio emission.

    From January 1985 to December 1994, 23 early stage carcinomas of the esophagus were treated by photodynamic therapy in 21 patients. The stage of the tumors was assessed by esophagoscopy with multiple biopsies, CT scan and, from June 1991, also by endoscopic ultrasonography: 7 lesions were classified as carcinoma in situ (Tis) and 16 as invasive (T1). The photosensitizers used for PDT were hematoporphyrin derivative 3 mg/kg in 4 patients and dihematoporphyrin ether 2 mg/kg in 17. Light irradiation was performed using an Argon-dye laser system at a wavelength of 630 nm with an average energy of 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. A complete response was achieved in 17/23 (74%) tumors, 15/21 (71%) patients. In the follow-up period from 6 to 78 months (median 36 months) 3 recurrences occurred 6, 12, and 14 months after PDT, respectively. Seven patients died due to concomitant diseases, not related to tumor progression. The actuarial survival rate was 95%, 75% and 37% at 1, 3, and 5 years, respectively. Complications included 1 case of sunburn and 2 cases of esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage.

    We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (P(trend) = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (P(trend) = 0.005) but not cases (P(trend) = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (P(het) = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (OR(het) = 0.84, 95% CI 0.75, 0.94; OR(hom) = 0.81, 95% CI 0.51, 1.30; P(trend) = 0.002) but not for those who had their menarche age ≤11 years (OR(het) = 1.06, 95% CI 0.95, 1.19, OR(hom) = 1.07, 95% CI 0.67, 1.72; P(trend) = 0.29). To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between later age at menarche and a reduction in

    Purpose Nearly 1 in 4 breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. Methods Literature review Results Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies first pregnancy. Evidence on childhood diet and growth in height, and adolescent alcohol intake, among other adolescent factors are related to breast cancer risk and risk of premalignant proliferative benign lesions. Conclusion Breast cancer prevention efforts will have the greatest effect when initiated at an early age and continued over a lifetime. Gaps in knowledge are identified and deserve increase attention to inform prevention. PMID:24820413

    Women become infertile approximately 10 years before menopause, and as more women delay childbirth into their 30s, the number of women who experience infertility is likely to increase. Tests that predict the timing of menopause would allow women to make informed reproductive decisions. Current predictors are only effective just prior to menopause, and there are no long-range indicators. Age at menopause and early menopause (EM) are highly heritable, suggesting a genetic aetiology. Recent genome-wide scans have identified four loci associated with variation in the age of normal menopause (40-60 years). We aimed to determine whether theses loci are also risk factors for EM. We tested the four menopause-associated genetic variants in a cohort of approximately 2000 women with menopause≤45 years from the Breakthrough Generations Study (BGS). All four variants significantly increased the odds of having EM. Comparing the 4.5% of individuals with the lowest number of risk alleles (two or three) with the 3.0% with the highest number (eight risk alleles), the odds ratio was 4.1 (95% CI 2.4-7.1, P=4.0×10(-7)). In combination, the four variants discriminated EM cases with a receiver operator characteristic area under the curve of 0.6. Four common genetic variants identified by genome-wide association studies, had a significant impact on the odds of having EM in an independent cohort from the BGS. The discriminative power is still limited, but as more variants are discovered they may be useful for predicting reproductive lifespan.

    The aims of this study were to introduce a paediatric early warning score (PEWS) into our daily clinical practice, as well as to evaluate its ability to detect clinical deterioration in children admitted, and to train nursing staff to communicate the information and response effectively. An analysis was performed on the implementation of PEWS in the electronic health records of children (0-15 years) in our paediatric ward from February 2014 to September 2014. The maximum score was 6. Nursing staff reviewed scores >2, and if >3 medical and nursing staff reviewed it. Monitoring indicators: % of admissions with scoring; % of complete data capture; % of scores >3; % of scores >3 reviewed by medical staff, % of changes in treatment due to the warning system, and number of patients who needed Paediatric Intensive Care Unit (PICU) admission, or died without an increased warning score. The data were collected from all patients (931) admitted. The scale was measured 7,917 times, with 78.8% of them with complete data capture. Very few (1.9%) showed scores >3, and 14% of them with changes in clinical management (intensifying treatment or new diagnostic tests). One patient (scored 2) required PICU admission. There were no deaths. Parents or nursing staff concern was registered in 80% of cases. PEWS are useful to provide a standardised assessment of clinical status in the inpatient setting, using a unique scale and implementing data capture. Because of the lack of severe complications requiring PICU admission and deaths, we will have to use other data to evaluate these scales. Copyright © 2016 SECA. Published by Elsevier Espana.

  13. Early Results of a Modular Cementless Tibial Component for Total Knee Arthroplasty

    Directory of Open Access Journals (Sweden)

    Raj Sinha, MD, PhD

    2014-10-01

    Full Text Available Cementless components in TKA have been used for almost 3 decades, despite mixed success rates. However, biologic fixation remains attractive, especially for younger patients, because of the potential of unlimited durability. This paper is the first to report results on a modular tibial base plate using trabecular metal as a fixation surface. Twenty-four primary TKAs were evaluated clinical and radiographically at mean 1.9 year followup. Excellent clinical results were obtained. There was no significant subsidence or change in orientation of any component. One component was probably loose radiographically but was insufficiently symptomatic to warrant revision. Five components showed nonprogressive radiolucent lines. One reoperation was performed for stiffness, at which time the components were well fixed. Thus, it would appear that excellent bony fixation can be achieved with a modular cementless tibial component with excellent short-term clinical results.

    2011-03-01

    Full Text Available Abstract Background The Mayo Lung Project (MLP, a randomized controlled clinical trial of lung cancer screening conducted between 1971 and 1986 among male smokers aged 45 or above, demonstrated an increase in lung cancer survival since the time of diagnosis, but no reduction in lung cancer mortality. Whether this result necessarily indicates a lack of mortality benefit for screening remains controversial. A number of hypotheses have been proposed to explain the observed outcome, including over-diagnosis, screening sensitivity, and population heterogeneity (initial difference in lung cancer risks between the two trial arms. This study is intended to provide model-based testing for some of these important arguments. Method Using a micro-simulation model, the MISCAN-lung model, we explore the possible influence of screening sensitivity, systematic error, over-diagnosis and population heterogeneity. Results Calibrating screening sensitivity, systematic error, or over-diagnosis does not noticeably improve the fit of the model, whereas calibrating population heterogeneity helps the model predict lung cancer incidence better. Conclusions Our conclusion is that the hypothesized imperfection in screening sensitivity, systematic error, and over-diagnosis do not in themselves explain the observed trial results. Model fit improvement achieved by accounting for population heterogeneity suggests a higher risk of cancer incidence in the intervention group as compared with the control group.

    The article discusses preliminary clinical results in patients with proximal femoral fractures treated with hemiarthroplasty using a FENIX implant. The study group comprised 41 subjects aged 69 to 97 (median age 82.3 year). The follow-up study provided data on 26 subjects (63.4%), among which 15 attended the check-up, 5 subjects refused to visit at the Department and 6 subjects were reported as deceased. Median follow-up period amounted to 6.8 month (1 to 22 months). General hospitalization-related complications occurred in 8 patients (19.5%). During hospitalization no deaths occurred, in the deceased group 3 patients died within 12 months after surgery, while another 3 died after the twelve-month postoperative period (median of 13.3%). According to Merle d'Aubigne-Postel score favorable long-term results were observed in 9 patients (59.9%), 13 patients regained the level of motor function similar to the functional ability prior to fracture. The need to postpone the surgery due to general health status and impaired pre-operative motor function are significant negative prognostic factors. The results obtained were compared with previous efficacy studies on femoral fracture treatment using an Austin-Moore implant. Functional ability and self-reliance was higher in the FENIX group. FENIX arthroplasty effectively helps patients regain self-reliance and motor function thanks to its modular characteristics and anatmoical construction.

    Full Text Available Purpose. To investigate the predictability of simplifying mandibular overdenture treatment using one-stage surgery and early prosthetic loading of a single implant. Materials and Methods. Twenty edentulous patients with problematic existing mandibular dentures were treated. A single implant with a chemically modified surface (SLActive, Straumann AG, Basel, Switzerland was placed into the mandibular midline. The patients were recalled at 3, 6 and 12 months. Clinical assessments and marginal bone loss using standardized radiographs were recorded. All complications, failures and maintenance were noted. Visual analog-scale questionnaires were used to record patient satisfaction in five categories. ANOVA was used to determine differences between means of marginal bone loss and different categories of patient staisfaction (=0.05. Results. The 20 early loaded implants were all surviving at the 12-month recall. All implants showed less than 1 mm of marginal bone loss by the end of the 1-year with a significant increase during the follow-up period. Few prosthetic problems were reported. Patient satisfaction was high with a significant increase in all comfort and functional parameters. Conclusions. These preliminary 1-year results indicate that early loading of a single chemically modified surface implant used to retain a mucosa-borne mandibular overdenture is a safe, reliable, and cost-effective treatment.

    Purpose. Previous clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction. Methods. Thirty-nine patients with inoperable malignant biliary obstruction were included. These patients underwent intraductal biliary radiofrequency ablation of their malignant biliary strictures following external biliary decompression with an internal-external biliary drainage. Following ablation, they had a metal stent inserted. Results. Following this intervention, there were no 30-day mortality, hemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the 39 patients, 28 are alive and 10 patients are dead with a median survival of 89.5 (range 14-260) days and median stent patency of 84.5 (range 14-260) days. One patient was lost to follow-up. All but one patient had their stent patent at the time of last follow-up or death. One patient with stent blockage at 42 days postprocedure underwent percutaneous transhepatic drain insertion and restenting. Among the patients who are alive (n = 28) the median stent patency was 92 (range 14-260) days, whereas the patients who died (n = 10) had a median stent patency of 62.5 (range 38-210) days. Conclusions. In this group of patients, it appears that this new approach is feasible and safe. Efficacy remains to be proven in future, randomized, prospective studies.

    The authors described the results of therapy of 74 spinal hemangioma patients. The patients were divided into 2 groups: 1 - radiotherapy only; 2 - radiotherapy following surgical intervention for enhanced symptoms of spinal compression. γ-beam therapy was given 5 times a week at a single dose of 0.8-1.2 Gy. An integral dose delivered to the cervical spine was 26-32 Gy, to the thoracic spine 28-30 Gy, to the lumber spine - 30-34 Gy. Field sizes varied from 3x4 to 3x12 cm depending on lesion spreading. Therapy also included traction on a special platform bed. An analysis of delayed therapeutic results (from 3 to 13 yrs.) has shown that clinical convalescence with regained working capacity in the 1st group (40 patients) was observed in 21 patients, in the 2nd group (34 patients) - in 5 patients only. Partial functional restoration was observed in both groups (19 patients in each group). The therapy applied was ineffective in 10 patients of the 2nd group

    In the past decade, the popularity of minimally invasive procedures for facial rejuvenation has increased. To describe a new specialized suture, and its associated technique, used to elevate sagging tissues of the face and neck. A detailed description of the technique and the results obtained in 20 patients in whom we have used this novel approach. Attention was given to appropriate patient selection. The primary focus was on the correction of the jowl, jawline, and neck subunits. It involves the percutaneous introduction of a novel 3-0 polypropylene suture that has 10 absorbable hollow cones along its axis that are equally interspersed with knots. Once the absorbable cones are resorbed into the surrounding tissues, the non-absorbable suture component can be removed without compromising the aesthetic outcome. All patients demonstrated improvement in these areas, with minimal complications. One patient required resuspension using the open technique. (Excessive ptotic tissue was later excised for an optimal cosmetic result.) The suture and technique described in this article provide a major contribution to the correction of ptosis of facial tissues. When done in conjunction with other procedures, such as neck and jowl microliposuction, this technique has proven to be a useful addition to facial rejuvenation.

    Introduction: Thyroid cancer is the most common endocrine malignancy. The current gold standard for diagnosis, fine-needle aspiration (FNA) biopsy, yields 10-25% of indeterminate cytology results, leading to patients undergoing thyroidectomy for diagnosis. We assessed the technical potential of a miniaturized in vivo ESS (elastic light scattering spectroscopy) probe, built into an FNA needle assembly, to differentiate benign from malignant thyroid nodules. Methods: Under IRB approval, 15 patients in the endocrine clinic undergoing FNAB of a thyroid nodule had collection of ESS data using our novel miniaturized FNA probe. Using final surgical pathology as our gold standard, data post processing and visual inspection was completed. Results: 225 spectra were grouped and analyzed (120 benign, 30 malignant and 75 from indeterminate cytology). ESS probes demonstrated excellent reproducibility in use. Initial analysis of these preliminary data is promising, indicating distinction of spectral ESS features between malignant and benign conditions. Conclusion(s): An in vivo trial of an invasive miniaturized integrated ESS biopsy probe is acceptable to patients, and collection of ESS data is feasible and reliable. With development of a disease-specific algorithm, ESS could potentially be used as an in-situ real time intra-operative diagnostic tool or as a minimally invasive adjunct to conventional FNA cytology.

  7. Hearing taboo words can result in early talker effects in word recognition for female listeners.

    Previous spoken word recognition research using the long-term repetition-priming paradigm found performance costs for stimuli mismatching in talker identity. That is, when words were repeated across the two blocks, and the identity of the talker changed reaction times (RTs) were slower than when the repeated words were spoken by the same talker. Such performance costs, or talker effects, followed a time course, occurring only when processing was relatively slow. More recent research suggests that increased explicit and implicit attention towards the talkers can result in talker effects even during relatively fast processing. The purpose of the current study was to examine whether word meaning would influence the pattern of talker effects in an easy lexical decision task and, if so, whether results would differ depending on whether the presentation of neutral and taboo words was mixed or blocked. Regardless of presentation, participants responded to taboo words faster than neutral words. Furthermore, talker effects for the female talker emerged when participants heard both taboo and neutral words (consistent with an attention-based hypothesis), but not for participants that heard only taboo or only neutral words (consistent with the time-course hypothesis). These findings have important implications for theoretical models of spoken word recognition.

    OBJECTIVE: To present and evaluate an unselected national single center strategy with fertility preserving trachelectomy in cervical cancer. In 2003 nationwide single-center referral of women for trachelectomies was agreed upon between all Danish departments performing cervical cancer surgery...... a total of 77 pregnancies. Of the 72 women 40 were referred to fertility treatment. First and second trimester miscarriage rates were 21.6% and 2.7%, respectively.

    Some preliminary new results are presented of the keV plasma experiment on GEOS-1. Electrons and ions have been observed to stream along the magnetic field lines in the dayside magnetosphere from the ionospheric side of the satellite towards the equatorial plane during magnetic storms, with streaming velocities corresponding to a kinetic energy of the order of a keV. The opposite streaming velocity has also been seen, but primarily in the ions only and with a smaller flux ratio for the two opposite directions along the field lines. The transition between the two opposite streaming directions, as seen by the satellite, has been found to occur even in a fraction of a second. In magnetic storm conditions azimuthal asymmetries in ion fluxes corresponding to electric field intensities of several tens of millivolts per meter have been observed. (Auth.)

    Systemic amyloid light-chain (AL) amyloidosis is associated with rapidly progressive and fatal cardiomyopathy resulting from the direct cardiotoxic effects of circulating AL light chain (AL-LC) proteins and the indirect effects of AL fibril tissue infiltration. Cardiac amyloidosis is resistant to standard heart failure therapies, and, to date, there are limited treatment options for these patients. The mechanisms underlying the development of cardiac amyloidosis and AL-LC cardiotoxicity are largely unknown, and their study has been limited by the lack of a suitable in vivo model system. Here, we establish an in vivo zebrafish model of human AL-LC-induced cardiotoxicity. AL-LC isolated from AL cardiomyopathy patients or control nonamyloidogenic LC protein isolated from multiple myeloma patients (Con-LC) was directly injected into the circulation of zebrafish at 48 h postfertilization. AL-LC injection resulted in impaired cardiac function, pericardial edema, and increased cell death relative to Con-LC, culminating in compromised survival with 100% mortality within 2 wk, independent of AL fibril deposition. Prior work has implicated noncanonical p38 MAPK activation in the pathogenesis of AL-LC-induced cardiotoxicity, and p38 MAPK inhibition via SB-203580 rescued AL-LC-induced cardiac dysfunction and cell death and attenuated mortality in zebrafish. This in vivo zebrafish model of AL-LC cardiotoxicity demonstrates that antagonism of p38 MAPK within the AL-LC cardiotoxic signaling response may serve to improve cardiac function and mortality in AL cardiomyopathy. Furthermore, this in vivo model system will allow for further study of the molecular underpinnings of AL cardiotoxicity and identification of novel therapeutic strategies.

    There are doubts about the age limit for lung donors and the ideal donor has traditionally been considered to be one younger than 55 years. The objective of this study was to compare the outcomes in lung transplantation between organs from donors older and younger than 60 years. We performed a retrospective observational study comparing the group of patients receiving organs from donors 60 years or older (Group A) or younger than 60 years (Group B) between January 2007 and December 2011. Postoperative evolution and mortality rates, short-term and mid-term postoperative complications, and global survival rate were evaluated. We analysed a total of 230 lung transplants, of which 53 (23%) involved lungs from donors 60 years of age or older (Group A), and 177 (77%) were from donors younger than 60 years (Group B). Three (5.7%) patients from Group A and 14 patients (7.9%) from Group B died within 30 days (P = 0.58). The percentage of patients free from chronic lung allograft dysfunction at 1-3 years was 95.5, 74.3 and 69.3% for Group A, and 94.5, 84.8 and 73.3% for Group B, respectively (P = 0.47). There were no statistically significant differences between Groups A and B in terms of survival at 3 years, (69.4 vs 68.8%; P = 0.28). Our results support the idea that lungs from donors aged 60-70 years can be used safely for lung transplantation with comparable results to lungs from younger donors in terms of postoperative mortality and mid-term survival. © The Author 2014.

    Indian women with breast cancer are usually diagnosed in advanced stages leading to poor survival. Improving breast awareness and increasing access to early diagnosis and adequate treatment has been advocated for breast cancer control. We implemented a program to increase awareness on breast cancer and access to its early detection in an occupational health care scheme in Mumbai, India. Breast awareness brochures were mailed annually between June 2013 and June 2016 to a cohort of 22,500 eligible women aged 30-69 years old receiving universal health care from an occupational health care scheme comprising of primary health centres and a referral secondary care hospital in Mumbai. Women with suspected breast cancers were provided with diagnostic investigations and treatment. Socio-demographic information and tumour characteristics were compared between the breast awareness pre-intervention period (Jan 2005-May 2013) and the breast awareness intervention period after four rounds of mailers (June 2013-June 2016). The proportion of women with early tumours and axillary lymph node negative cancers increased from 74% to 81% and 46% to 53% respectively, between the two periods. While the proportion of patients receiving breast conserving surgery increased from 39% to 51%, the proportion receiving chemotherapy decreased from 84% to 56%. Interim results following efforts to improve breast awareness and access to care in a cohort of women in an occupational health care scheme indicate early detection and more conservative treatment of breast cancers. Creating awareness and improving access to care may result in cancer down-staging. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To evaluate the results and prognostic factors for postoperative adjuvant radiation therapy in patients at stages I and II of endometrial cancer. Materials and Methods: Between January 1991 and December 2006, 35 patients with FIGO stages I and II disease, who received adjuvant radiation therapy following surgery for endometrial cancer at Ewha Womans University Hospital, were enrolled in this study. A total of 17 patients received postoperative pelvic external beam radiation therapy; whereas, 12 patients received vaginal brachytherapy alone, and 6 patients received both pelvic radiation therapy and vaginal brachytherapy. Results: The median follow-up period for all patients was 54 months. The 5-yr overall survival and disease-free survival rates for all patients were 91.4% and 81.7%, respectively. The 5-yr overall survival rates for low-risk, intermediate-risk, and high-risk groups were 100%, 100% and 55.6%, respectively. In addition, the 5-yr disease-free survival rates were 100%, 70.0%, and 45.7%, respectively. Although no locoregional relapses were identified, distant metastases were observed in 5 patients (14%). The most common site of distant metastases was the lung, followed by bone, liver, adrenal gland, and peritoneum. A univariate analysis revealed a significant correlation between distant metastases and risk-group (p=0.018), pathology type (p=0.001), and grade (p=0.019). A multivariate analysis also revealed that distant metastases were correlated with pathology type (p=0.009). Papillary, serous and clear cell carcinoma cases demonstrated a poor patient survival rate compared to cases of endometrioid adenocarcinoma or adenosquamous carcinoma. The most common complication of pelvic external beam radiation therapy was enteritis (30%), followed by proctitis, leucopenia, and lymphedema. All these complications were of RTOG grades 1 and 2; no grades 3 and 4 were observed. Conclusion: For the low-risk and intermediate-risk groups (stages 1 and 2) endometrial

    Purpose: To retrospectively evaluate treatment results and toxicity following a combined approach consisting of neoadjuvant radiochemotherapy and radical surgery in advanced adenocarcinoma of the esophagus and gastroesophageal junction. Patients and Methods: Between 2005 and 2009, a total of 41 consecutive patients with newly diagnosed nonmetastatic adenocarcinoma of the esophagus and the esophagogastric junction were evaluated, of whom 23 received neoadjuvant radiochemo-therapy (RCT). A total dose of 50.4 Gy with 2 cycles of simultaneous cisplatin/5-fluorouracil (FU) or Taxol/FU-chemotherapy were applied. A radical transthoracic subtotal esophageal and proximal gastric resection through a right thoracoabdominal laparotomy with intrathoracic anastomosis was performed 6-8 weeks following RCT. This was combined with a two-field lymphadenectomy of mediastinal and abdominal lymph nodes. Standard histopathological evaluation included the application of regression grading according to Werner and Hoefler. Toxicity was recorded on the basis of CTC criteria; survival curves were calculated according to Kaplan-Meier. V10, V15, and V20 data were correlated with pulmonary toxicity. Results: Overall survival for all 23 patients was 61% at 3 years. Of the original 23 patients, 18 (78%) patients proceeded to radical surgery. Reasons for no surgery included advanced age of 79, 82, and 86 years (n = 3), severe comorbidity (n = 1), and progression during radiochemotherapy (n = 1). Surgical morbidity (grade 3-4) and mortality rates were 35% and 6%, respectively. Resurgery was necessary in 3 cases (18%). Clear resection margins were achieved in 17 of 18 patients (94%). Twelve of 18 (67%) patients initially diagnosed with T3 tumors and 3 of 3 patients with T4 tumors experienced downstaging. The ypN0 rate was 12 of 18 patients (67%). Out of a total of 18 patients, regression grading revealed < 10% viable cells in 8 (44%) including 3 cases (17%) with complete regression, 10-50% viable

    The aim of this study was to assess the safety and efficiency of biodegradable self-reinforced (SR-PLDLA) bone plates and screws in open reduction and internal fixation of mandible fractures in children. Thirteen patients (5 female, 8 male; mean age 12 years, range 5-16 years) were operated on various fractures of the mandible (2 symphyseal, 6 parasymphyseal, 4 body, 3 angle, 1 ramus, 2 condylar fractures). The mean follow-up time was 26.4 months (range 10.9-43.4 months). Intermaxillary fixation was applied in cases with concomitant condylar fractures up to 3 weeks. Primary healing of the fractured mandible was observed in all patients. Postoperative complications were minor and transient. The outcome of the operations was not endangered. Adverse tissue reactions to the implants, malocclusion, and growth restrictions did not occur during the observation period. Pediatric patients benefit from the advantages of resorbable materials, especially from faster mobilization and the avoidance of secondary removal operations. Based on these preliminary results, self-reinforced fixation devices are safe and efficient in the treatment of pediatric mandible fractures. However, further clinical investigations are necessary to evaluate the long-term reliability.

    Objective: To evaluate the technical feasibility of a new monorail-stent-balloon device for treatment of renal artery stenosis (RAS). Patients and Methods: During a study period of 18 months, 38 patients with proven RAS in 41 cases (hypertension n = 36, renal insufficiency n = 13) and indication for stenting (calicified ostial lesions n = 35, insufficient PTA n = 4, dissection n = 2) were enrolled into this prospective evaluation. Pre-mounted stents (Rx-Herculink TM 5 mm = 13, 6 mm = 34, 7 mm = 1) were implanted a transfermoral (n = 35) or transbrachial approach (n = 6). Mean grade and lengths of stenosis measured were 88% ±10 and 9 mm ±5. Results: Renal stent implantation was technically successful in all cases (100%). In 7 cases a second stent had to be implanted to cover the entire lesion. The transstenotic pressure drop decreased from 88 mmHg ± 10 before to 1 mmHg ± 1.8 after the procedure. Remaining stenosis measured 0.7% ±4.2. Serum creatine levels decreased from 1.9 mm/dl to 1.5 mg/dl (n.s.), blood pressure decreased from 178/94 mmHg to 148/79 mmHg (p [de

    The present study comprised sarcomeric genotyping of the three most commonly involved sarcomeric genes: MYBPC3, MYH7, and TNNT2 in 192 unrelated Egyptian hypertrophic cardiomyopathy (HCM) index patients. Mutations were detected in 40 % of cases. Presence of positive family history was significantly (p=0.002) associated with a higher genetic positive yield (49/78, 62.8 %). The majority of the detected mutations in the three sarcomeric genes were novel (40/62, 65 %) and mostly private (47/62, 77 %). Single nucleotide substitution was the most frequently detected mutation type (51/62, 82 %). Over three quarters of these substitutions (21/27, 78 %) involved CpG dinucleotide sites and resulted from C>T or G>A transition in the three analyzed genes, highlighting the significance of CpG high mutability within the sarcomeric genes examined. This study could aid in global comparative studies in different ethnic populations and constitutes an important step in the evolution of the integrated clinical, translational, and basic science HCM program.

    This paper presents the first results from a comparison of Planck dust maps at 353, 545 and 857GHz, along with IRAS data at 3000 (100 μm) and 5000GHz (60 μm), with Green Bank Telescope 21-cm observations of Hi in 14 fields covering more than 800 deg2 at high Galactic latitude. The main goal of this study is to estimate the far-infrared to sub-millimeter (submm) emissivity of dust in the diffuse local interstellar medium (ISM) and in the intermediate-velocity (IVC) and high-velocity clouds (HVC) of the Galactic halo. Galactic dust emission for fields with average Hi column density lower than 2 × 1020 cm-2 is well correlated with 21-cm emission because in such diffuse areas the hydrogen is predominantly in the neutral atomic phase. The residual emission in these fields, once the Hi-correlated emission is removed, is consistent with the expected statistical properties of the cosmic infrared background fluctuations. The brighter fields in our sample, with an average Hi column density greater than 2 × 1020 cm-2, show significant excess dust emission compared to the Hi column density. Regions of excess lie in organized structures that suggest the presence of hydrogen in molecular form, though they are not always correlated with CO emission. In the higher Hi column density fields the excess emission at 857 GHz is about 40% of that coming from the Hi, but over all the high latitude fields surveyed the molecular mass faction is about 10%. Dust emission from IVCs is detected with high significance by this correlation analysis. Its spectral properties are consistent with, compared to the local ISM values, significantly hotter dust (T ~ 20K), lower submm dust opacity normalized per H-atom, and a relative abundance of very small grains to large grains about four times higher. These results are compatible with expectations for clouds that are part of the Galactic fountain in which there is dust shattering and fragmentation. Correlated dust emission in HVCs is not detected

    We assessed the outcome of core through internal urethrotomy for traumatic posterior urethral stricture, and reviewed the followup results of these patients. During the last 4 years 13 patients with a stricture up to 2 cm. long underwent core through internal urethrotomy with C-arm fluoroscopy guidance and an orientation in 2 planes. Retrograde urethrotomy was performed and an 18F Foley catheter was left indwelling for 4 weeks, after which urethrotomy was repeated. All patients were advised to perform clean intermittent self-catheterization for urethral calibration and dilation. Outcome was defined as class 1-3 patients who required 2 or fewer urethrotomies with clean intermittent self-catheterization discontinued after the primary procedure, class 2-5 who required 2 or fewer urethrotomies with clean intermittent self-catheterization and class 3-5 who required 3 or more urethrotomies. Of the 13 patients 8 (61%) did well after a mean followup of 17.7 months. The 3 patients with a class 1 outcome did well, while 2 of 5 with a class 2 outcome required repeat urethrotomy during followup. Of the 5 patients (39%) with a class 3 outcome in whom core through internal urethrotomy failed 3 required open surgery and 2 were lost to followup. Recurrence rate was 69% at 3 months and 25% at 12 months after the initial procedure. No patient was incontinent at last followup. Two patients had significant hematuria postoperatively, which resolved with conservative treatment. Endoscopic treatment should be considered the first line procedure for all post-traumatic posterior urethral strictures. The morbidity of open surgery can be avoided in 61% of patients. Hospital stay, loss of work, morbidity and related complications are also markedly decreased with endoscopic therapy.

    Valve-sparing aortic root reconstruction (VSRR) is an accepted method to treat patients with aortic root dilation. The role of the VSRR is less well defined for patients with bicuspid aortic valve, severe aortic valve insufficiency, congenital heart defects, and type A aortic dissection. We studied the clinical outcome of patients who underwent VSRR for expanded indications. Seventy-eight patients underwent VSRR between the 2005 and 2012. Seventy-two patients (92%) underwent reimplantation and 6 patients (8%) were operated on with the remodeling technique. The mean age was 51 ± 12 years (range 24 to 73). For 71 patients (91%), the operation was elective, and for 7 (9%; all with type A aortic dissection), on an emergency basis. Preoperatively, the degree of aortic insufficiency was graded as 2+ or greater for 27 patients (35%). Connective tissue disorder (Marfan or Loeys-Dietz), bicuspid aortic valve, or congenital heart disease was present in 15 (19%), 15 (19%), and 7 patients (9%), respectively. Concomitant aortic valve leaflet repair was performed for 39 patients (50%). The mean follow-up time was 2.4 ± 1.7 years (range, 0.1 to 7.0). Thirty-day mortality was zero. The rate of postoperative complications was low: stroke 3%, renal failure 3%, prosthesis infection 1%, and low cardiac output syndrome 1%. Survival was 100% at 1 year and 97% at 5 years. Freedom from recurrent aortic valve insufficiency (≥2+) during the follow-up was 94%. The midterm results of VSRR in terms of survival, freedom from recurrent aortic valve insufficiency, and the need for reoperation are excellent, even for high-risk patients.

    to assess the intake, frequency, and type of milk consumed by Brazilian children younger than 60 months of age. this was a cross-sectional study, which used secondary data from the National Demographic and Health Survey of 2006-2007. Data from 4,817 children under the age of 60 months were used. All analyses were performed with expanded samples. The dietetic survey assessed the previous day's consumption, and estimates were made through univariate analysis, presented as a percentage. on the day prior to the survey, breast milk was consumed by 91% of the children younger than six months of age, by 61.5% of the children aged 6 to 12 months, and by 34.8% of the children aged 13 to 24 months. Among the children who had received other types of milk, cow's milk was consumed by 62.4% of the children younger than six months, by 74.6% of the children aged 6 to 12 months, and by approximately 80% of the children older than 12 months. Infant formulas were consumed by 23% of the children younger than six months of age, by 9.8% of the children aged 6 to 12 months, and by less than 1% of the older children. Soy milk consumption varied from 14.6% to 20% among the investigated ages. Non-breast milk consumption before the age of six months was more frequent in children living in the Northeastern and Southern regions. the results of the present study demonstrated that most children received cow's milk prematurely as a substitute for breast milk, highlighting the importance of the development of public policies to promote, protect, and support breastfeeding in all regions of Brazil, aiming at reversing the observed scenario.

    Our previous results from Raman spectroscopy studies on ex vivo lung tissue showed the technique had great potential to differentiate between samples with different pathologies. In this work, a fast dispersive-type near-infrared (NIR) Raman spectroscopy system was developed to collect real-time, noninvasive, in vivo human lung spectra. The 785 nm excitation, and the collection of tissue emission were accomplished by using a reusable fiber optic catheter which passed down the instrument channel of a bronchoscope. Filters in two stages blocked laser emission other than 785 nm from reaching the tissue surface, and reduced fiber fluorescence and elastically scattered excitation light from being passed to the spectrometer. The spectrometer itself consisted of one of two holographic gratings with usable frequency ranges of: 700 to 2000 cm -1 and 1500 to 3400 cm -1. The dispersed light was detected by a cooled CCD array consisting of 400 by 1340 pixels. To increase the resolution of the system, while maximizing the throughput, a second fiber bundle, consisting of 54×100 μm diameter fibers connected the catheter to the spectrometer. The fibers in this second bundle were spread out to form a parabolic arc which replaced the conventional entrance slit. This geometry corrected for image aberrations, permitting complete CCD vertical binning, thereby yielding up to a 20-fold improvement in signal-to-noise ratio. The estimated spectral resolution of the system was 9 cm -1 for both gratings. So far we have measured spectra from 20 patients and have seen clear differences between spectra from tumor and normal tissue.

    Purpose. To evaluate clinically a new, retrievable vena caval filter in a multicenter study. Methods. The Tulip filter is a stainless steel half-basket that is suitable for antegrade or retrograde insertion via an 8.5 Fr introducer sheath. The filter can be retrieved via the jugular approach using an 11 Fr coaxial retrieval system. Forty-eight filters were implanted via the femoral approach and 38 via the jugular approach in 83 patients. Follow-up examinations (plain films, colorcoded duplex sonography) were performed up to 3 years after filter insertion (mean 136 days) in 75 patients. Twenty-seven patients were screened by colorcoded duplex sonography for insertion site thrombosis. Results. An appropriate filter position was achieved in all cases. Insertion problems occurred in 3 cases; these were not due to the filter design but to an imperfect prototype insertion mechanism that has now been modified (n=2) or a manipulation error (n=1). In 2 of these cases the filters were replaced percutaneously; 1 patient required venotomy for filter removal. No further complications due to filter insertion occurred. Two filters were used as temporary devices and were successfully removed after 6 and 11 days, respectively. There was 1 fatal recurrent pulmonary embolism (PE) and 2 non-fatal PE, 5 complete and 3 partial caval occlusions, and 3 caudal migrations of the filter. Insertion site venous thrombosis was not seen in the 27 patients monitored for this complication. Conclusion. Precise placement of the Tulip filter is feasible by either access route and the device appears mechanically stable. Further observations are needed to confirm that safe filter removal is practical up to 10 days after its insertion

    Purpose: Three-dimensional conformal radiotherapy (3D-CRT) has been associated with a reduction in acute and late toxicity among patients treated for localized prostatic cancer. The purpose of this study is to assess the acute and late toxicity of 3D-CRT delivered to patients in the postprostatectomy setting and to analyze which factors predict for durable biochemical control in this group of patients. Methods and Materials: Between 1988 and 1994, 42 patients were treated after prostatectomy with three-dimensional conformal radiotherapy. The median time from prostatectomy to radiotherapy was 11 months. Indications for treatment included a rising serum PSA level in 28 patients (65%) and positive surgical margins without a rising PSA level in 14 (35%). Twenty-five patients (60%) had pathologic stage T3 disease, and 32 (74%) had tumor at or close to the surgical margins. The median dose was 64.8 Gy, and the median follow-up time was 2 years. Results: 3D-CRT in the postprostatectomy setting was well tolerated. Three patients (7%) experienced Grade II acute genitourinary toxicity and nine patients (21%) experienced Grade II acute gastrointestinal toxicity during treatment. No patient experienced Grade III or higher acute morbidity. The 2-year actuarial risk for Grade II late genitourinary and gastrointestinal late complications were 5 and 9%, respectively. In patients with existing incontinence, the incidence of worsening stress incontinence 6 months after treatment was 17%, which resolved within 12 months to its preradiotherapy level in four of six cases (66%). The overall 2-year postirradiation PSA relapse-free survival rate was 53%. The 2-year PSA relapse-free survival was 66% for patients with undetectable PSA levels in the immediate postoperative period compared to 26% for those with detectable levels of PSA after surgery (p 1.0 ng/ml (p 1 ng/ml (p < 0.002) was the most important covariate predicting for a rising PSA after radiotherapy. Conclusions: After

    A new approximately 117 Ma paleomagnetic pole has been defined from the study of volcanic and plutonic rocks from the eastern portion Marie Byrd Land (MBL). The new pole (185.6 deg E/56.8 deg S, A(sub 95) = 8.7 deg) implies that the eastern portion of MBL was an integral part of Weddellia, which included the ancestral Antarctic Peninsula, Thurston Island, and Ellsworth-Whitmore Mountains blocks of West Antarctica. This pole is generally similar to a approximately 125 Ma pole from Thurston Island. Both poles call for major clockwise rotation and poleward motion of eastern MBL and Thurston Island between the Early Cretaceous (125-117 Ma) and the mid-Cretaceous (110-100 Ma). We propose that in the Early Cretaceous, eastern MBL and the Eastern Province of New Zealand were part of a continuous active Pacific margin of Gondwana, connecting with the Antarctic Peninsula, and distinct from western MBL, the Western Province of New Zealand, and North Victoria Land. These western terranes are thought to have accreted to Gondwana in the Devonian. Eastern MBL and the Eastern Province of New Zealand amalgamated with western MBL and the Western Province of New Zealand by the mid-Cretaceous. Major Early Cretaceous motions of the Weddellia blocks postdate the estimated initiation of seafloor spreading in the Weddell Sea and therefore may be the result of plate reorganization during the Cretaceous Quiet Zone.

    Full Text Available Abstract Background A strong inverse relationship of functional limitation and socioeconomic status has been established in western ageing society. Functional limitation can be related to chronic diseases, disuse, cognitive decline, and ageing. Among chronic diseases in the Thai population, cerebrovascular diseases, diabetes, and arthritis are common. These factors are known to contribute to disability and poor quality of life in the elder population. Neuropsychiatric problems, cognitive decline, dementia, and cultural issues in elderly people also can alter the quality of life of the elderly. Methods The Dementia and Disability Project in Thai Elderly (DDP aims at comprehensively assessing community dwelling Thai elderly to understand the relationship between disability and motor function, neuropsychiatric symptoms, cognitive function, and chronic diseases. The DDP is the first study to look at the prevalence and etiology of dementia and of mild cognitive impairment (MCI in Thai elders and to explore the relationship of cognition, disability, small vessel diseases and cortical degeneration with neuroimaging in Thai elderly people. 1998 Thai elders were screened in 2004–2006 and diagnosed as having MCI or dementia. 223 elders with MCI or dementia and cognitively normal elderly had brain magnetic resonance imaging (MRI or at baseline. 319 elders from the 3 groups had blood tests to investigate the risks and possible etiologies of dementia including genotyping at baseline. Results The mean age of elders in this study is 69.51(SD=6.71, min=60, max=95 years. 689(34.9% are men and 1284(65.1% are women. Mean body weight was 58.36(SD=11.20 kgs. The regression model reveals that performance on gait and balance and serum triglyceride predicts activity of daily living performance (adjusted r2 = 0.280, f=2.644, p=0.003. The majority of abnormal gait in Thai elders was lower level gait disturbance. Only 1.5% (29/1952 had highest level gait disorders. 39

    Uncertainty and sensitivity analysis techniques based on Latin hypercube sampling, partial correlation analysis and stepwise regression analysis were used in an investigation with the MACCS model of the early health effects associated with a severe accident at a nuclear power station. The following results were obtained in tests to check the robustness of the analysis techniques: two independent Latin hypercube samples produced similar uncertainty and sensitivity analysis results; setting important variables to best-estimate values produced substantial reductions in uncertainty, while setting the less important variables to best-estimate values had little effect on uncertainty; similar sensitivity analysis results were obtained when the original uniform and loguniform distributions assigned to the 34 imprecisely known input variables were changed to left-triangular distributions and then to right-triangular distributions; and analyses with rank-transformed and logarithmically-transformed data produced similar results and substantially outperformed analyses with raw (i.e., untransformed) data

    2002-01-01

    There was a good response to our questionnaire on the Bulletin (around 450 so far). Many thanks to all of you - your views are invaluable to us. Pending publication of the full figures, which will give latecomers time to take part in the survey, here we give here answers some of your most frequent comments. Thank you for the many warm tributes and messages of encouragement we received. We also received criticisms about the way information is handled in the Bulletin and on its circulation. In today's issue we reply to these two points. Why is the Bulletin politically correct ? Many respondents reproach the Bulletin for a lack of objectivity and for being too politically correct to the point of being a propaganda organ. It is true that the Bulletin is not a newspaper, but rather a bulletin of communication (like SLAC's Beam Line). What is the difference ? A newspaper is objectively independent of the subjects it reports on, and when its reporters write stories they dig around for information from all parties...

    To determine whether the results from previous research suggesting that early intensive health care delays recovery from whiplash-associated disorders (WADs) were confounded by expectations of recovery and whether the association between early health care intensity and time to recovery varies across patterns of health care. Population-based inception cohort. All adults (≥18y) injured in motor vehicle collisions who received treatment from a regulated health professional or reported their injuries to the single provincially administered motor vehicle insurer. Participants with WAD (N=5204). Self-report visits to physicians, chiropractors, physiotherapists, massage therapists, and other professionals during the first 42 days postcollision were used to define health care intensity. Not applicable. Self-perceived recovery. Individuals with high utilization health care had slower recovery independent of expectation of recovery and other confounders. Compared with individuals who reported low utilization of physician services, recovery was slower for those with high health care utilization, regardless of the type of profession. For instance, those with high physician (hazard rate ratio [HRR]=.56; 95% confidence interval [CI], .42-.75), physician and high physiotherapy utilization (HRR=.68; 95% CI, .61-.77), physician and high chiropractor utilization (HRR=.74; 95% CI, .64-.85), and physician and high massage therapy utilization (HRR=.78; 95% CI, .68-.90) had significantly slower recovery. Our study adds to the existing evidence that early intensive care is associated with slower recovery from WAD, independent of expectation of recovery. The results have policy implications and suggest that the optimal management of WADs focuses on reassurance and education instead of intensive care.

    2012-01-01

    Purpose: To evaluate the feasibility, implementation, and early results of noninvasive breast brachytherapy (NIBB) for tumor bed boost with whole breast radiation therapy (WBRT). Methods and Materials: NIBB is a commercially available (AccuBoost, Billerica, MA) mammography-based, brachytherapy system in which the treatment applicators are centered on the planning target volume (PTV) to direct 192 Ir emissions along orthogonal axes. A privacy-encrypted online data registry collected information from 8 independent academic and community-based institutions. Data were from 146 consecutive women with early-stage breast cancer after lumpectomy and WBRT receiving boost with NIBB between July 2007 and March 2010. Toxicity and cosmesis were graded according to the Common Toxicity Criteria (v. 3.0) and the Harvard scale. Median follow-up was 6 months (1–39 months). Results: Grade 1–2 skin toxicity was observed in 64%, 48%, and 21% during the acute (1–3 weeks), intermediate (4–26 weeks), and late-intermediate (>26 weeks) periods. There was no Grade 4 toxicity. At 6 months, for the entire cohort, cosmesis was excellent/good in 62%/38%. The subset receiving NIBB before WBRT had cosmetic scores of 32% and 63%, whereas during WBRT, 58% and 37% were rated as excellent and good, respectively. Breast compression was scored as “uncomfortable” in 12%, 29%, and 59% when NIBB was delivered before, during, or after WBRT. For each patient, the fraction-to-fraction variability in PTV was low. Skin flash was associated with a higher proportion of excellent cosmesis (58% vs. 42%) relative to having the applicator all within breast tissue. Conclusions: These data indicate that NIBB is feasible and can be consistently implemented in a broad array of practice settings. Preliminary evaluation suggests that NIBB is associated with acceptably mild normal tissue toxicity and favorable early cosmesis. The application of NIBB before WBRT may be associated with better patient tolerance at

    Purpose: To assess the feasibility of utilizing 3-dimensional conformal accelerated partial-breast irradiation (APBI) in the preoperative setting followed by standard breast-conserving therapy. Patients and Methods: This was a prospective trial testing the feasibility of preoperative APBI followed by lumpectomy for patients with early-stage invasive ductal breast cancer. Eligible patients had T1-T2 ( 21 days after radiation therapy. Adjuvant therapy was given as per standard of care. Results: Twenty-seven patients completed treatment. With a median follow-up of 3.6 years (range, 0.5-5 years), there have been no local or regional failures. A complete pathologic response according to hematoxylin and eosin stains was seen in 4 patients (15%). There were 4 grade 3 seromas. Patient-reported cosmetic outcome was rated as good to excellent in 79% of patients after treatment. Conclusions: Preoperative 3-dimensional conformal radiation therapy−APBI is feasible and well tolerated in select patients with early-stage breast cancer, with no reported local recurrences and good to excellent cosmetic results. The pathologic response rates associated with this nonablative APBI dose regimen are particularly encouraging and support further exploration of this paradigm.

  16. I-FABP as biomarker for the early diagnosis of acute mesenteric ischemia and resultant lung injury.

    Directory of Open Access Journals (Sweden)

    Rachel G Khadaroo

    Full Text Available Acute mesenteric ischemia (AMI is a life-threatening condition that can result in multiple organ injury and death. A timely diagnosis and treatment would have a significant impact on the morbidity and mortality in high-risk patient population. The purpose of this study was to investigate if intestinal fatty acid binding protein (I-FABP and α-defensins can be used as biomarkers for early AMI and resultant lung injury. C57BL/6 mice were subjected to intestinal ischemia by occlusion of the superior mesenteric artery. A time course of intestinal ischemia from 0.5 to 3 h was performed and followed by reperfusion for 2 h. Additional mice were treated with N-acetyl-cysteine (NAC at 300 mg/kg given intraperitoneally prior to reperfusion. AMI resulted in severe intestinal injury characterized by neutrophil infiltrate, myeloperoxidase (MPO levels, cytokine/chemokine levels, and tissue histopathology. Pathologic signs of ischemia were evident at 1 h, and by 3 h of ischemia, the full thickness of the intestine mucosa had areas of coagulative necrosis. It was noted that the levels of α-defensins in intestinal tissue peaked at 1 h and I-FABP in plasma peaked at 3 h after AMI. Intestinal ischemia also resulted in lung injury in a time-dependent manner. Pretreatment with NAC decreased the levels of intestinal α-defensins and plasma I-FABP, as well as lung MPO and cytokines. In summary, the concentrations of intestinal α-defensins and plasma I-FABP predicted intestinal ischemia prior to pathological evidence of ischemia and I-FABP directly correlated with resultant lung injury. The antioxidant NAC reduced intestinal and lung injury induced by AMI, suggesting a role for oxidants in the mechanism for distant organ injury. I-FABP and α-defensins are promising biomarkers, and may guide the treatment with antioxidant in early intestinal and distal organ injury.

    Objective: To evaluate the clinical outcome and cosmetic results in early stage breast cancer patients treated with conservative surgery plus radiation therapy. Methods: From May 1995 to December 2002, 109 such patients were so treated. The post-operative radiotherapy consisted of whole-breast 6 MV linear accelerator irradiation with two tangential half-fields to a total dose of 45-52 Gy (mean 48.6 Gy), followed by a boost irradiation to the tumor bed. Among them, 79 patients received 10-12 Gy (DB) boost by interstitial implantation brachytherapy ( 192 Ir HDR, Nucletron), with single plane implantation for T1 and double plane implantation for T2 tumor. Thirty patients received 15 Gy boost by electron beam. Adjuvant/concurrent chemotherapy (CMF or CEF) and hormonotherapy were also used according to the patients' clinical characteristics. The cosmetic results were scored by both the doctor and the patients. Results: The overall actuarial 5-year survival was 93.8%, with local recurrence of 6.5%. No radiation-induced ulcer was observed in the breast except for acute inflammation at skin pinholes in 5 patients treated by interstitial implant brachytherapy. Among the 75 patients who had had breast examination, cosmetic result scored as good by patient and doctor were 81% and 87%, respectively. The good rate assessed by doctor in brachytherapy boost group and electron beam boost group were 81.2% (39/48) and 85.2% (23/27), There was no significant difference between these two boost techniques (P>0.05). Conclusions: Tumor bed boost irradiation by either brachytherapy or electron beam technique can provide satisfactory local control in early breast cancer treated with conservative surgery plus radiotherapy without increasing the side effects. There is no significant difference in cosmetic result between these two boost techniques. (authors)

    Purpose: To retrospectively review the results of a single-institution series of accelerated hypofractionated radiotherapy for early-stage non-small-cell lung cancer (NSCLC) in patients who are medically inoperable or who refuse surgery. Methods and Materials: Peripherally located T1 to T3 N0 M0 tumors were treated with 48 to 60 Gy in 12 to 15 fractions between 1996 and 2007. No elective nodal irradiation was delivered. Patient, tumor, and treatment information was abstracted from the medical records. Results: A total of 124 tumors were treated in 118 patients (56 male and 62 female). Median age at diagnosis was 76.3 years (range, 49-90 years). In all, 113 patients (95.8%) were not surgical candidates because of medical comorbidities. The 2- and 5-year overall survival (OS) rates were 51.0% and 23.3%, respectively, and the 2- and 5-year cause-specific survival (CSS) rates were 67.6% and 59.8%, respectively. The 2- and 5-year actuarial local control (LC) rates were 76.2% and 70.1%, respectively. Univariate analysis revealed that tumor size less than 3cm compared with greater than 3 cm resulted in significantly improved OS (40.0% vs. 5.0% at 5 years; p = 0.0002), CSS (69.7% vs. 45.1% at 5 years; p = 0.0461), and a trend toward better LC (82.5% vs. 66.9% at 2 years, 76.6% vs. 60.8% at 5 years; p = 0.0685). Treatment was well tolerated and there were no treatment delays because of acute toxicity. Conclusions: Accelerated hypofractionated radiotherapy with 48 to 60 Gy using fractions of 4 Gy per day provides very good results for small tumors in medically inoperable patients with early-stage NSCLC.

    2016-03-01

    Purpose: To prospectively evaluate high-dose-rate brachytherapy in the treatment of therapy-resistant keloids and report first results, with emphasis on feasibility and early treatment outcome. Methods and Materials: From 2009 to 2014, 24 patients with 32 recurrent keloids were treated with immediate perioperative high-dose-rate brachytherapy; 3 patients had been previously treated with adjuvant external beam radiation therapy and presented with recurrences in the pretreated areas. Two or more different treatment modalities had been tried in all patients and had failed to achieve remission. After (re-)excision of the keloids, a single brachytherapy tube was placed subcutaneously before closing the wound. The target volume covered the scar in total length. Brachytherapy was given in 3 fractions with a single dose of 6 Gy in 5 mm tissue depth. The first fraction was given within 6 hours after surgery, the other 2 fractions on the first postoperative day. Thus, a total dose of 18 Gy in 3 fractions was administered within 36 hours after the resection. Results: The treatment was feasible in all patients. No procedure-related complications (eg, secondary infections) occurred. Nineteen patients had keloid-related symptoms before treatment like pain and pruritus; disappearance of symptoms was noticed in all patients after treatment. After a median follow-up of 29.4 months (range, 7.9-72.4 months), 2 keloid recurrences and 2 mildly hypertrophied scars were observed. The local control rate was 94%. Pigmentary abnormalities were detected in 3 patients, and an additional 6 patients had a mild delay in the wound-healing process. Conclusions: The early results of this study prove the feasibility and the efficacy of brachytherapy for the prevention of keloids. The results also suggest that brachytherapy may be advantageous in the management of high-risk keloids or as salvage treatment for failure after external beam therapy.

This exploratory study assessed the relationships between patient and physician characteristics and early outpatient satisfaction with care for alcohol and opioid dependence. Methods: Satisfaction was assessed using a multidimensional, self-administered and validated questionnaire during the early care process among a prospective outpatient cohort. In addition to measuring satisfaction and obtaining sociodemographic and clinical data, this study collected data on the self-reported health status and physician characteristics at inclusion. Cross-sectional analysis with multiple linear regression was performed to identify the variables associated with satisfaction level. Results: A total of 249 outpatients were included, and 63.8% completed the satisfaction questionnaire. Patients without a history of previous care for substance dependence were more satisfied with the appointment-making process (β=7.2; P=0.029 and with the doctor consultation (β=10.3; P=0.003 than those who had received care previously. Neither sociodemographic characteristics nor self-reported health status was associated with outpatient satisfaction. Conclusion: The factors that affect patients

    Full Text Available Background. This study examined the feasibility and acceptability of a home-based early childhood obesity prevention intervention designed to empower low-income racially/ethnically diverse parents to modify their children’s health behaviors. Methods. We used a prospective design with pre-/posttest evaluation of 50 parent-child pairs (children aged 2 to 5 years to examine potential changes in dietary, physical activity, and sedentary behaviors among children at baseline and four-month follow-up. Results. 39 (78% parent-child pairs completed evaluation data at 4-month follow-up. Vegetable intake among children significantly increased at follow-up (0.54 cups at 4 months compared to 0.28 cups at baseline, P=0.001 and ounces of fruit juice decreased at follow-up (11.9 ounces at 4 months compared to 16.0 ounces at baseline, P=0.036. Sedentary behaviors also improved. Children significantly decreased time spent watching TV on weekdays (P<0.01 and also reduced weekend TV time. In addition, the number of homes with TV sets in the child’s bedroom also decreased (P<0.0013. Conclusions. The findings indicate that a home-based early childhood obesity prevention intervention is feasible, acceptable and demonstrates short-term effects on dietary and sedentary behaviors of low-income racially/ethnically diverse children.

    Background and purpose: The goal of the present study was to comparatively assess the results of definitive chemoradiation (CRT) with or without previous macroscopically complete resection in patients with early-stage node-negative (T1-2 N0) anal carcinoma. Patients and methods: A total of 20 patients with T1-2 N0 anal carcinoma who received radiotherapy (RT) with or without chemotherapy following incidental R0/1 tumor resection (S/CRT group) were selected. These were matched to 20 comparable patients who underwent definitive chemoradiation without previous surgery (CRT group). Major objectives of this analysis were treatment outcomes in terms of locoregional tumor control (LRC), overall survival (OS), colostomy-free survival, and toxicity. Results: Patients treated postoperatively received significantly lower RT doses (median 54.0 Gy vs. 59.7 Gy; p < 0.001) and less frequently concomitant chemotherapy than those treated definitely. The 5-year LRC and 5-year OS rates were 97.5% and 90.0%, respectively, without significant differences between the S/CRT and the CRT groups. The distribution of acute and late toxicities was comparable, and the 5-year colostomy-free survival was 95% in both groups. Conclusion: This matched-pair comparison of incidental R0/1 resection plus dose-reduced CRT with standard definitive CRT of early-stage anal cancer shows similar treatment results. Thus, dose-reduced RT with or without chemotherapy may be considered in R0/1 resected patients with T1-2 N0 anal carcinoma. (orig.)

    Background The risk of recurrent stroke among patients with symptomatic carotid near-occlusion is not well established, and management of the condition remains controversial. Symptomatic carotid near-occlusion with full collapse has been identified as a strong predictor of early recurrence. We aimed to analyze the 90-day risk of recurrent ipsilateral ischemic stroke in medically treated patients with symptomatic carotid near-occlusion. Methods We performed a multicenter, nationwide, prospective study from January 2010 to May 2016. Patients with angiography-confirmed symptomatic carotid near-occlusion were included. The primary endpoint was ipsilateral ischemic stroke or transient ischemic attack (TIA) within 90 days after the presenting event. For this analysis, patients who underwent revascularization within 90 days after stroke were excluded. Results The study population comprised 141 patients from 17 Spanish centers; 83 patients were treated medically. Primary endpoint occurred in eight patients, resulting in a cumulative rate of 10.6% (95% CI, 3.7-17.5). Previous history of stroke or transient ischemic attack was identified as an independent predictor for recurrence in the multivariate Cox regression analysis (HR, 4.37 [95% CI, 1.05-18.18]; p = 0.043), while the presence of full collapse was not associated with an increased risk (HR, 0.81 [95% CI, 0.17-3.92]; p = 0.793). The risk of recurrence was also not affected by the presence of significant stenosis or occlusion of the contralateral carotid artery, or by the collateral circulation. Conclusions Patients with symptomatic carotid near-occlusion seem to have an increased risk of early ipsilateral recurrent stroke. Our results contrast with the low risk of symptomatic carotid near-occlusion reported to date. Full collapse did not increase the risk of recurrent stroke in our study.

    Full Text Available The present study aimed to evaluate the effects of Ramadan fasting on the level of sex hormones in girls between 9-13 years before age at menarche.This study was conducted on a sample of 58 subjects (age range: 9-13 years, who were divided intotwo groups of fasting (N=31 and non-fasting (N=27. The levels of follicle-stimulating hormone(FSH, luteinizing hormone (LH, progesterone and estradiol were measured in all the subjectsbefore and after Ramadan. Measurements were carried out three days before the start of Ramadan,and one day afterwards.In this study, FSH levels significantly increased in the non-fasting group (P=0.01, and the level ofDehydroepiandrostenedione (DHEA had a significant decrease during the time of study in bothgroups (P=0.001, P=0.006. In addition, serum levels of LH significantly increased in the non-fastinggroup after Ramadan (P=0.006, and estradiol significantly increased in both groups (P=0.008,P=0.004.Given the similar changes in the levels of DHEA, progesterone and estradiol in both study groups, itcould be concluded that fasting has no effects on these parameters, and the changes in LH and FSHlevels could be due to other contributing factors.

    Purpose: To evaluate the feasibility, implementation, and early results of noninvasive breast brachytherapy (NIBB) for tumor bed boost with whole breast radiation therapy (WBRT). Methods and Materials: NIBB is a commercially available (AccuBoost, Billerica, MA) mammography-based, brachytherapy system in which the treatment applicators are centered on the planning target volume (PTV) to direct {sup 192}Ir emissions along orthogonal axes. A privacy-encrypted online data registry collected information from 8 independent academic and community-based institutions. Data were from 146 consecutive women with early-stage breast cancer after lumpectomy and WBRT receiving boost with NIBB between July 2007 and March 2010. Toxicity and cosmesis were graded according to the Common Toxicity Criteria (v. 3.0) and the Harvard scale. Median follow-up was 6 months (1-39 months). Results: Grade 1-2 skin toxicity was observed in 64%, 48%, and 21% during the acute (1-3 weeks), intermediate (4-26 weeks), and late-intermediate (>26 weeks) periods. There was no Grade 4 toxicity. At 6 months, for the entire cohort, cosmesis was excellent/good in 62%/38%. The subset receiving NIBB before WBRT had cosmetic scores of 32% and 63%, whereas during WBRT, 58% and 37% were rated as excellent and good, respectively. Breast compression was scored as 'uncomfortable' in 12%, 29%, and 59% when NIBB was delivered before, during, or after WBRT. For each patient, the fraction-to-fraction variability in PTV was low. Skin flash was associated with a higher proportion of excellent cosmesis (58% vs. 42%) relative to having the applicator all within breast tissue. Conclusions: These data indicate that NIBB is feasible and can be consistently implemented in a broad array of practice settings. Preliminary evaluation suggests that NIBB is associated with acceptably mild normal tissue toxicity and favorable early cosmesis. The application of NIBB before WBRT may be associated with better patient tolerance

    The aim of this study was a comparison of early and late results in surgical treatment of funnel chest using the Nuss method in patients in various age groups to find the optimal age to perform the corrective procedure. Six hundred eighty patients operated on from June 2002 to October 2012 were included in the retrospective analysis. Patients were divided into 3 different age groups: group A = 156 patients from 7 to 14 years, group B = 328 patients aged 15 to 20 years, and group C = 196 patients older than 20 years of age. The mean follow-up was 33 months. Early non-life-threatening complications developed in 238 (35.0%) patients and frequency increased with age (group A, 24.3%; group B, 37.8%; group C, 38.8%; p = 0.0063). Good and very good corrective effects were achieved in 97.7 % of the entire patient population. Recurrence of the deformity was observed more often in younger patients (group A, 3.2 %) than in the other patients (group B, 1.2%; group C, 1.5%), although the difference between the studied groups was not significant (p = 0.3251). Good cosmetic results obtained with the use of the Nuss operation were not related to the age of the patients. The high incidence of minor complications in older patients seems to be an acceptable cost of a good cosmetic outcome and stable correction. Surgical morbidity is lowest in younger patients; however, the frequency of the recurrence of deformation is higher than in other groups. Copyright © 2016 The Society of Thoracic Surgeons.

    Full Text Available Background: In recent years, laparoscopic sleeve gastrectomy (LSG has become more acceptable for obese patients. Single-port sleeve gastrectomy (SPSG is more popular since each abdominal incision carries the risk of bleeding, hernia, and internal organ injury as well as exponentially affecting cosmesis. This cross-sectional study aimed at comparing multi-port sleeve gastrectomy (MPSG and SPSG in terms of their early results and complications. Methods: Out of129 obese patients candidated for LSG, 102 patients were assigned to 2 groups of SPSG and MPSG. Complications and demographic data such as body mass index (BMI, age, gender, operation time, and hospital stay were measured. All surgeries were carried out between2013 and 2015 in Shiraz, Iran. Data analysis was performed using SPSS, version 16 for Windows (SPSS Inc., Chicago, IL. The continuous and categorical variables were compared using the Student t-test and the Chi-square test or the Fisher exact test, respectively. Results: The patients’ data from both groups were similar in terms of age, intraoperative and postoperative bleeding volume, and length of hospital stay. Mean BMI was 42.8±0.7 in the SPSG group and 45.3±1.2 in the MPSG group. Duration of surgery was significantly lower in the SPSG group (P<0.001. Only 1 patient from the SPSG group and 5 patients from the MPSG group had bleeding as an early complication. Conclusion: The differences in each complication between the groups were not statistically significant. SPSG seems to be safe and is the same as MPSG in terms of major postoperative complications.

    The results of marine bacterial community succession from a short-term study of seawater incubations at 4°C to North Sea crude oil are presented herein. Oil was used alone (O) or in combination with a dispersant (OD). Marine bacterial communities resulting from these incubations were characterized by a fingerprinting analysis and pyrosequencing of the 16S rRNA gene with the aim of 1) revealing differences in bacterial communities between the control, O treatment, and OD treatment and 2) identifying the operational taxonomic units (OTUs) of early responders in order to define the bacterial gene markers of oil pollution for in situ monitoring.After an incubation for 1 d, the distribution of the individual ribotypes of bacterial communities in control and oil-treated (O and OD) tanks differed. Differences related to the structures of bacterial communities were observed at later stages of the incubation. Among the early responders identified (Pseudoalteromonas, Sulfitobacter, Vibrio, Pseudomonas, Glaciecola, Neptunomonas, Methylophaga, and Pseudofulvibacter), genera that utilize a disintegrated biomass or hydrocarbons as well as biosurfactant producers were detected. None of these genera included obligate hydrocarbonoclastic bacteria (OHCB). After an incubation for 1 d, the abundances of Glaciecola and Pseudofulvibacter were approximately 30-fold higher in the OD and O tanks than in the control tank. OTUs assigned to the Glaciecola genus were represented more in the OD tank, while those of Pseudofulvibacter were represented more in the O tank. We also found that 2 to 3% of the structural community shift originated from the bacterial community in the oil itself, with Polaribacter being a dominant bacterium.

  11. "Big Bang" as a result result of the curvature-driven first-order phase transition in the early cold Universe

    Science.gov (United States)

    Pashitskii, E. A.; Pentegov, V. I.

    We suggest that the "Big Bang" may be a result of the first-order phase transition driven by changing scalar curvature of the 4D space-time in the expanding cold Universe, filled with nonlinear scalar field φ and neutral matter with equation of state p = vɛ (where p and ɛ are pressure and energy density of matter). We consider a Lagrangian for scalar field in curved space-time with nonlinearity φ, which along with the quadratic term -ΣR|φ|2 (where Σ is interaction constant and R is scalar curvature) contains a term ΣR(φ +φ+) linear in φ. Due to this term the condition for the extrema of the potential energy of the scalar field is given by a cubic equation. Provided v > 1/3 the scalar curvature R = [κ(3v-1)ɛ - 4Γ (where κ and Γ are Einstein's gravitational and cosmological constants) decreases along with decreasing " in the process of the Universe's expansion, and at some critical value Rc < 0 a first-order phase transition occurs, driven by an "external field" parameter proportional to R. Given certain conditions the critical radius of the early Universe at the point of the first-order phase transition may reach arbitrary large values, so this scenario of unrestricted "inflation" of the Universe may be called "hyperinflation". Beyond the point of phase transition the system is rolling down into the potential minimum releasing the potential energy of scalar field with subsequent powerful heating of the Universe playing the role of "Big Bang".

    The aim of this study was to present outcomes of primary Latitude total elbow replacement (TER) with a minimum follow-up of 2 years. A retrospective cohort study was undertaken with prospective outcome data collection for the latest outcome. Included were 63 consecutive primary Latitude TERs in 58 patients performed during a period of 5 years at a specialist orthopedic hospital. The mean age of the patients was 62 years (33-85 years). Five primary TERs (4 patients) were lost to follow-up. The primary diagnosis was rheumatoid arthritis in 49, osteoarthritis in 8, and trauma in 6 elbows. The mean flexion-extension arc was 75° preoperatively and 97° postoperatively. Mean postoperative Elbex pain score was 19/100, and function score was 37/100. Mean postoperative scores were 42/100 for the Quick Disabilities of the Arm, Shoulder, and Hand and 38/50 for the elbow-specific American Shoulder and Elbow Surgeons assessment. Four patients died of unrelated causes, and 8 of 63 underwent further surgical intervention, including explantation and conversion from unlinked to linked implant. On radiographic review of 41 surviving TERs, aseptic radiologic loosening was observed of the humeral component in 4 elbows and of the ulnar component in 9. Seven elbows had no radial component, and of the remaining 34 elbows, 16 (47%) had signs of loosening of the radial implant. Complications included 1 heterotopic ossification, 1 olecranon fracture, and 3 further procedures for ulnar nerve entrapment. The results indicate that the early outcome of Latitude TER is comparable to that of other prostheses. There is concern about early radiologic loosening of the radial component.

    As part of the WFC3 Early Release Science observations, a portion of the GOODS-S field was observed with both the UVIS and IR Channels of the WFC3. The full data set of 100 orbits covers 50 square arcminutes on the sky at 0.09 arcseconds per pixel with ten broad bands covering 0.2-1.7 microns. The field was observed in F225W, F275W, and F336W to 10 sigma point source flux limits of 26.0, 26.1, and 25.7 AB-mag, respectively. In this poster, we will emphasize the results enabled by these UV observations of faint galaxies. We demonstrate that these UV observations are extremely useful, even for galaxies of intermediate redshifts (zdropout galaxies, AGN, etc. In particular, optical and near-IR studies only measure the rest-frame UV properties of the highest redshift galaxies, and for comparison these UV observations are needed to properly study galaxy evolution near the peak of the global star formation rate density. In fact, deeper UV observations, below the atmospheric cutoff, and with space-based resolution, are need to properly study galaxies at the faint-end of the luminosity function at z 1. This paper is based on Early Release Science observations made by the WFC3 Scientific Oversight Committee.

    Early integration of palliative care in oncology practice ("simultaneous care", SC) has been shown to provide better care resulting in improved quality-of-life and also survival. We evaluated the opinions of Italian Association of Medical Oncology (AIOM) members. A 37-item questionnaire was delivered to 1119 AIOM members. Main areas covered were: social, ethical, relational aspects of disease and communication, training, research, organizational and management models in SC. Three open questions explored the definition of Quality of Life, Medical Oncologist and Palliative Care. Four hundred and forty-nine (40.1%) medical oncologists returned the questionnaires. Forty-nine percent stated they address non-curability when giving a diagnosis of metastatic tumor, and 43% give the information only to patients who clearly ask for it. Fifty-five percent say the main formative activity in palliative medicine came from attending meetings and 90% agree that specific palliative care training should be part of the core curriculum in oncology. Twenty-two percent stated they consulted guidelines for symptom management, 45% relied upon personal experience and 26% make a referral to a palliative care specialist. Seventy-four percent were in favor of more research in palliative medicine. An integration between Units of Oncology and Palliative Care Services early in the course of advanced disease was advocated by 86%. Diverse and multifaceted definitions were given for the concepts of Quality of Life, Palliative Care and Medical Oncologist. SC is felt as an important task, as well as training of medical oncologists in symptom management and research in this field.

  15. Refining the Early and Middle Eocene Geomagnetic Polarity Time Scale: new results from ODP Leg 208 (Walvis Ridge)

    Astronomical calibration of the Geomagnetic Polarity Time Scale (GPTS) for the Eocene (34-56 Ma) has advanced tremendously in recent years. Combining a cyclostratigraphic approach based on the recognition of the stable 405-kyr eccentricity cycle of Earth's orbit with high-resolution bio- and magnetostratigraphy from deep-sea sedimentary records (ODP Legs 171B, 189 and 207; IODP Exp. 320/321) resulted in a new calibration of the middle-to-late Eocene GPTS spanning Chrons C12r to C19n (30.9-41.3 Ma). A fully astronomically calibrated GPTS for the Eocene was established recently by integrating cyclo-bio-magnetostratigraphy from ODP Sites 702 and 1263 records spanning the middle Eocene with Site 1258 records covering the early Eocene. Comparison of this deep sea-derived GPTS with GTS2012 and GPTS calibration points from terrestrial successions show overall consistent results, but there are still major offsets for the duration of Chrons C20r, C22r and C23n.2n. Because of the relatively large uncertainty of the calibration point, a radioisotopic dated ash layer in DSDP 516F, at C21n.75 (46.24±0.5 Ma) the duration of C20r in GPTS2012 (2.292 myr) is uncertain. Offsets in durations of C22r and C23n.2n between GPTS2012 and the new astronomical GPTS (~400-kyr longer C22r; ~400-kyr shorter C23n.2n) could be due to uncertainties in the interpretation of Site 1258 magnetostratigraphic data. Here we present new results toward establishing a more accurate and complete bio-, magneto- and chemostratigraphy for South Atlantic Leg 208 sites encompassing magnetochrons C13 to C24 (33 to 56 Ma). Our study aims to integrate paleomagnetic records from multiple drilled sites with physical property data, stable isotope data and XRF core scanning data to construct an astronomically calibrated framework for refining GPTS age estimates. This effort will complete the Early-to-Middle Eocene GPTS and allow evaluation of the relative position of calcareous nannofossil events to magnetostratigraphy.

  18. Interocular suppression in strabismic amblyopia results in an attenuated and delayed hemodynamic response function in early visual cortex.

    Science.gov (United States)

    Farivar, Reza; Thompson, Benjamin; Mansouri, Behzad; Hess, Robert F

    2011-12-20

    Factors such as strabismus or anisometropia during infancy can disrupt normal visual development and result in amblyopia, characterized by reduced visual function in an otherwise healthy eye and often associated with persistent suppression of inputs from the amblyopic eye by those from the dominant eye. It has become evident from fMRI studies that the cortical response to stimulation of the amblyopic eye is also affected. We were interested to compare the hemodynamic response function (HRF) of early visual cortex to amblyopic vs. dominant eye stimulation. In the first experiment, we found that stimulation of the amblyopic eye resulted in a signal that was both attenuated and delayed in its time to peak. We postulated that this delay may be due to suppressive effects of the dominant eye and, in our second experiment, measured the cortical response of amblyopic eye stimulation under two conditions--where the dominant eye was open and seeing a static pattern (high suppression) or where the dominant eye was patched and closed (low suppression). We found that the HRF in response to amblyopic eye stimulation depended on whether the dominant eye was open. This effect was manifested as both a delayed HRF under the suppressed condition and an amplitude reduction.

  19. Early Results of Three-Year Monitoring of Red Wood Ants’ Behavioral Changes and Their Possible Correlation with Earthquake Events

    Simple Summary For three years (2009–2012), two red wood ant mounds (Formica rufa-group), located at the seismically active Neuwied Basin (Eifel, Germany), have been monitored 24/7 by high-resolution cameras. Early results show that ants have a well-identifiable standard daily routine. Correlation with local seismic events suggests changes in the ants’ behavior hours before the earthquake: the nocturnal rest phase and daily activity are suppressed, and standard daily routine does not resume until the next day. At present, an automated image evaluation routine is being applied to the video streams. Based on this automated approach, a statistical analysis of the ant behavior will be carried out. Abstract Short-term earthquake predictions with an advance warning of several hours or days are currently not possible due to both incomplete understanding of the complex tectonic processes and inadequate observations. Abnormal animal behaviors before earthquakes have been reported previously, but create problems in monitoring and reliability. The situation is different with red wood ants (RWA; Formica rufa-group (Hymenoptera: Formicidae)). They have stationary mounds on tectonically active, gas-bearing fault systems. These faults may be potential earthquake areas. For three years (2009–2012), two red wood ant mounds (Formica rufa-group), located at the seismically active Neuwied Basin (Eifel, Germany), have been monitored 24/7 by high-resolution cameras with both a color and an infrared sensor. Early results show that ants have a well-identifiable standard daily routine. Correlation with local seismic events suggests changes in the ants’ behavior hours before the earthquake: the nocturnal rest phase and daily activity are suppressed, and standard daily routine does not resume until the next day. At present, an automated image evaluation routine is being applied to the more than 45,000 hours of video streams. Based on this automated approach, a statistical analysis of

    Spondyloarthritis (SpA) is a heterogeneous disease with hardly predictable potential courses. We aimed at determining prognostic factors of bad functional outcome at 2 years in patients with early inflammatory back pain (IBP). Data from patients included in the French multicentre devenir des spondylarthropathies indifférenciées récentes (DESIR) cohort, that is, suffering from IBP starting before 50 years of age and lasting for 3-36 months, were used. A bad functional outcome at 24 months was defined as an increase in bath ankylosing spondylitis functional index (BASFI), or BASFI at 2 years higher than the 75th centile in the cohort. Demographic, clinical, biological and radiological data collected at inclusion were compared in patients with bad functional outcome versus others, by χ(2) test, then by a multivariate logistic regression model with stepwise selection of relevant factors. 513 patients (54.4% females, 72.2% fulfilling ASAS criteria) were assessed. Of those, 130 (25.3%) fulfilled the aforementioned criteria of a bad functional outcome (BASFI increase ≥4 units or ≥36 at 2 years). Multivariate analysis revealed that not fulfilling ASAS criteria, female sex, age >33 years, lower educational level, active smoking status and high disease activity according to bath ankylosing spondylitis disease activity index (BASDAI) at baseline were independently associated with a bad functional outcome at 24 months. Sensitivity analyses restricted to patients fulfilling ASAS criteria for SpA resulted in similar results. We observed, in a large prospective cohort of patients with early IBP, formerly described bad prognostic factors, especially a low educational level, an older age and a high disease activity at onset, and revealed that active smoking status and female sex were also independently associated with a poor outcome. Fulfilment of ASAS criteria, on the other hand, was predictive of a better outcome, most likely due to the more consensual

    Full Text Available Abstract Background In many countries age at pubertal onset has declined substantially. Relatively little attention has been paid to how this decline may affect adolescent behaviours such as substance use, violence and unprotected sex and consequently impact on public health. Methods In the UK, two opportunistic samples (aged 16-45 years, paper-based (n = 976 and online (n = 1117, examined factors associated with earlier pubertal onset and whether earlier age of onset predicted sexual risk-taking, substance use and anti-social behaviours during early adolescence. Results Overall, 45.6% of females reported menarche ≤ 12 years and 53.3% of males were categorised as having pubertal onset ≤ 11 years. For both sexes earlier pubertal onset was associated with poorer parental socio-economic status. Other pre-pubertal predictors of early onset were being overweight, more childhood illnesses (females and younger age at time of survey (males. For both sexes earlier puberty predicted having drunk alcohol, been drunk, smoked and used drugs Conclusion Results provide sufficient evidence for changes in age of pubertal onset to be further explored as a potential influence on trends in adolescent risk behaviours. Further insight into the relationship between early puberty and both obesity and socio-economic status may help inform early interventions to tackle the development of risk behaviours and health inequalities during early adolescence.

    Full Text Available CONTEXT AND OBJECTIVES: There are few studies concerning bone marrow mononuclear cell (BMMC transplantation in cases of nonischemic dilated cardiomyopathy. This study describes a novel technique of BMMC transplantation and the results up to one year after the procedure. DESIGN AND SETTING: This was a case series to evaluate the safety and viability of the procedure, at Instituto de Cardiologia do Rio Grande do Sul. METHODS: Nine patients with symptomatic dilated cardiomyopathy, functional class III/IV and left ventricular ejection fraction (LVEF < 35% received BMMC (9.6 ± 2.6 x 107 cells at 20 sites in the ventricular wall, by means of thoracotomy of length 5 cm in the fifth left intercostal space. Echocardiograms and nuclear magnetic resonance (NMR were performed. RESULTS: There were no major complications. The functional class results for the first six patients (preoperatively and at two, four, eight and twelve-month follow-ups, respectively were: [IV-2, III-4] to [I-5, II-1] to [I-3, II-3] to [I-2, II-3] and [I-2, II-3]. Echocardiograms showed LVEF: 25.9 ± 8.2; 32.9 ± 10.4; 29.4 ± 7.2; 25.1 ± 7.9; 25.4 ± 6.8% (p = 0.023; and % left ventricular (LV fiber shortening: 12.6 ± 4.4; 16.4 ± 5.4; 14.3 ± 3.7; 12.1 ± 4.0; 12.2 ± 3.4% (p = 0.021. LV performance variation seen on NMR was non-significant. CONCLUSION: Intramyocardial transplantation of BMMC in dilated cardiomyopathy cases is feasible and safe. There were early improvements in symptoms and LV performance. Medium-term evaluation revealed regression of LV function, although maintaining improved functional class.

    Objective: Objective To study the method, side effects and cosmetic outcome of high- dose-rate (HDR) accelerated partial breast interstitial irradiation (APBI) alone in early stage breast cancer' after conservative surgery. Methods: From February 2002 to June 2003,47 breast cancer lesions from 46 patients suffering from stage I/II breast cancer were treated with HDR 192 Ir APBI after conservative surgery. All patients were over 40 year-old, with T1-2N0-1 (≤3 lymph nodes positive), surgical margin > 1-2 mm, but those having lobular or inflammatory breast cancer were excluded. HDR brachytherapy with 34 Gy, 10 fractions/5 days was used after surgery, toxic reaction and cosmetic outcome were observed in one month, 6 and 12 months respectively. Results: Follow up of 1846 months, 34 months was carried out for the whole group. During the treatment, acute reactions including: erythema, edema, tenderness and infection, all under I-II grade, none of III-IV grade were observed in 21 patients(46%); late toxicity reactions: skin fibrosis, breast tenderness, fat necrosis, and telangiectasia, totally 20 patients (43%) were observed: 2 patients in III grade but one patient received 6 cycle chemotherapy. The result of cosmetic outcome evaluation was excellent or good, at 6 months 95% and 12 months 98%, respectively, but there was no recurfence. Conclusions: Excellent and favorable cosmetic results are noted after APBI by interstitial alone. Acute and late reactions are few. Long term observation is necessary for the rate of' local control.

    We determined the prevalence of work disability in early rheumatoid arthritis (ERA) and undifferentiated early inflammatory arthritis (EIA) patients at first enrollment into the Canadian Early Arthritis Cohort (CATCH) who met the 2010 ACR criteria versus those not meeting criteria, to determine the impact of meeting new criteria on work disability status. Data at first visit into the cohort were analyzed. Descriptive statistics and logistic regression analyses were performed to investigate the association of other variables in our database with work disability. 1,487 patients were enrolled in the CATCH study, a multi-site observational, prospective cohort of patients with EIA. 934 patients were excluded (505 based on missing criteria for ACR 2010 classification, as anti-CCP was absent, and 429 were not working for other reasons). Of the 553 patients included, 71 % were female with mean disease duration of 6.4 months. 524 (94.8 %) were employed while 29 (5.2 %) reported work disability at first visit. There were no differences between those meeting 2010 ACR criteria versus those who did not. Baseline characteristics associated with work disability were male gender, age, education, income, HAQ, and positive RF status. The mean HAQ score in work disabled patients was 1.4 versus 0.9 in those who were working (p 50 years; p = 0.3), lower education (p = 0.3) or RF positivity (p = 0.6). We found rates of work disability to be low at entry into this EIA cohort compared to previous studies. There may be potential for intervention in ERA to prevent the development of work disability.

    To assess the efficacy of a novel percutaneous "device-less" suture mediated patent foramen ovale (PFO) closure system. Between June 2016 and October 2017, a prospective registry aimed at assessing the safety and efficacy of the NobleStitch EL (HeartStitch, Fountain Valley, CA) suture-based PFO closure system was carried out at 12 sites in Italy. Among 200 consecutive evaluated patients, 192 were considered suitable for suture-mediated PFO closure (44±13 years, 114 women). Suture of the septum with the NobleStitch EL system was carried out successfully in 186 (96%) patients. Median fluoroscopy time was 16.1 (13.0-22.5) minutes and contrast volume 200 (150-270) ml. At 206±130 days follow-up, microbubbles transthoracic echocardiography with Valsalva maneuver revealed no RLS (grade 0) in 139 (75%) patients and RLS grade ≤1 in 166 (89%) patients. Significant RLS was present in 20 (11%) patients (grade 2 and 3 in 11 and 9 patients, respectively). There were no device-related complications. The early results of this first Italian Registry indicates that the suture mediated "deviceless" closure of PFO is feasible in the majority of septal anatomies, provides an effective closure of PFO comparable to traditional devices with an excellent safety profile at medium term follow-up.

    Perianal Crohn's disease (CD) represents a more aggressive phenotype of inflammatory bowel disease and often coincides with proctocolitis. This study aims to assess the outcome of patients undergoing proctectomy with end-colostomy. A retrospective outcome analysis of 10 consecutive patients who underwent intersphincteric proctectomy with end-colostomy between February 2007 and May 2011 was performed. All patients suffered from refractory distal and perianal CD. The proximal colon was normal at endoscopy. All data were extracted from a prospectively maintained database. The main outcome parameter was disease recurrence and need for completion colectomy. Severe and early endoscopic recurrence in the proximal colon occurred in 9/10 patients at a median time interval of 9.5 months (range: 1.9-23.6 months). Despite protracted medical treatment, completion colectomy was necessary in 5 patients. One patient, who underwent a second segmental colectomy with a new end-colostomy, showed again endoscopic recurrence and is currently treated with anti-TNF agents. Intersphincteric proctectomy with colostomy seems to be an ineffective surgery for perianal CD with coexisting proctitis and results in a high risk of recurrence of the disease in the remaining colon. Therefore, despite a normal appearance of the proximal colon, a proctocolectomy with end-ileostomy seems to be the surgical approach of choice in these patients.

    2013-02-01

    Full Text Available Short-term earthquake predictions with an advance warning of several hours or days are currently not possible due to both incomplete understanding of the complex tectonic processes and inadequate observations. Abnormal animal behaviors before earthquakes have been reported previously, but create problems in monitoring and reliability. The situation is different with red wood ants (RWA; Formica rufa-group (Hymenoptera: Formicidae. They have stationary mounds on tectonically active, gas-bearing fault systems. These faults may be potential earthquake areas. For three years (2009–2012, two red wood ant mounds (Formica rufa-group, located at the seismically active Neuwied Basin (Eifel, Germany, have been monitored 24/7 by high-resolution cameras with both a color and an infrared sensor. Early results show that ants have a well-identifiable standard daily routine. Correlation with local seismic events suggests changes in the ants’ behavior hours before the earthquake: the nocturnal rest phase and daily activity are suppressed, and standard daily routine does not resume until the next day. At present, an automated image evaluation routine is being applied to the more than 45,000 hours of video streams. Based on this automated approach, a statistical analysis of the ants’ behavior will be carried out. In addition, other parameters (climate, geotectonic and biological, which may influence behavior, will be included in the analysis.

    Background: To evaluate the value of radiotherapy and immediate hormonal therapy in the treatment of stage C prostate cancer. Patients and Method: From 1977 to 1986, 169 patients with clinically stage C prostate cancer underwent irradiation with curative intent following early orchiectomy. Sixty-four patients had a transurethral resection, 22 patients a prostatectomy and 83 patients had only a biopsy. In 38 patients a grade Ia/b tumor was found, in 78 patients a grade IIa/b tumor and in 43 patients a grade IIIa/b tumor using the German grade of malignancy. Treatment fields included the prostate, the seminal vesicles and the locoregional lymphatics. Until 1979 the dose was 60 Gy for the tumor encompassing isodose and from then on 65 Gy with a single dose of 2 Gy. Results: With a median follow-up of 98 months, the overall survival rate for 8 and 10 years was 51% and 37% and the cause-specific survival rate was 84% and 77%, respectively. Thirty-two patients (19%) developed distant metastases. Patients with local tumor control (n=148) had a significantly better overall survival rate of 45% for 10 years compared to patients with clinical local progression of disease (n=21) of 22% (p [de

    In 2011 Medicare initiated a Bundled Payment for Care Improvement (BPCI) program with the goal of introducing a payment model that would "lead to higher quality, more coordinated care at a lower cost to Medicare." A Model 2 bundled payment initiative for Total Joint Replacement (TJR) was implemented at a large, tertiary, urban academic medical center. The episode of care includes all costs through 90 days following discharge. After one year, data on 721 Medicare primary TJR patients were available for analysis. Average length of stay (LOS) was decreased from 4.27 days to 3.58 days (Median LOS 3 days). Discharges to inpatient facilities decreased from 71% to 44%. Readmissions occurred in 80 patients (11%), which is slightly lower than before implementation. The hospital has seen cost reduction in the inpatient component over baseline. Early results from the implementation of a Medicare BPCI Model 2 primary TJR program at this medical center demonstrate cost-savings.

    The along-track scanning radiometer (ATSR) was launched in July 1991 on the European Space Agency's first remote sensing satellite, ERS 1. An initial analysis of ATSR data demonstrates that the sea surface temperature (SST) can be measured from space with very high accuracy. Comparison of simultaneous measurements of SST made from ATSR and from a ship-borne radiometer show that they agree to within 0.3°C. To assess data consistency, a complementary analysis of SST data from ATSR was also carried out. The ATSR global SST field was compared on a daily basis with daily SST analysis of the United Kingdom Meteorological Office (UKMO). The ATSR global field is consistently within 1.0°C of the UKMO analysis. Also, to demonstrate the benefits of along-track scanning SST determination, the ATSR SST data were compared with high-quality bulk temperature observations from drifting buoys. The likely causes of the differences between ATSR and the bulk temperature data are briefly discussed. These results provide early confidence in the quantitative benefit of ATSR's two-angle view of the Earth and its high radiometric performance and show a significant advance on the data obtained from other spaceborne sensors. It should be noted that these measurements were made at a time when the atmosphere was severely contaminated with volcanic aerosol particles, which degrade infrared measurements of the Earth's surface made from space.

    Auto-ethnographic accounts can highlight unsaid moments of professional practice. In this case, my auto-ethnographic tale 'Le moment de la lune' re-inscribes subjugated knowledge about menstruation and occupational therapy practice in the era before adolescent wards. This fictional tale is written in direct dialogue with an article that was published in this journal at a particular point in my own career as an occupational therapist. In the tale I am 'writing in' what was not written about in my article and in occupational therapy generally. This 'writing-in'/re-inscribing is the research method. My previous article 'Normal spaces' published in this journal in 1985, was organised around principles and generalities of youth-specific practice. The original article had little locating the personal or evoking the body and a heavy reliance on the literature. Issues of gender and culture were largely absent, or, perhaps, 'written out'. The corresponding tale of embodied sexuality, 'Le moment de la lune', articulates something of local complex practice and the particularity of individual therapeutic work to do with menstruation in self-care. Points of tension in 'Normal spaces' are elaborated and I explain how 'Le moment de la lune' problematises supporting menarche in a children's hospital. Now practice has moved on with dedicated adolescent wards in all major children's hospitals. Nevertheless, occupational therapy practice around issues of menstrual self-management is still under-documented. Writing about unspoken moments of practice can have ethical implications for expanding the ways occupational therapy practice can be written and understood. © 2011 The Author.

    Vertebral fracture (or vertebral deformity) is a very common outcome of osteoporosis, which is one of the major public health concerns in the world. Early detection of vertebral fractures is important because timely pharmacologic intervention can reduce the risk of subsequent additional fractures. Chest radiographs are used routinely for detection of lung and heart diseases, and vertebral fractures can be visible on lateral chest radiographs. However, investigators noted that about 50% of vertebral fractures visible on lateral chest radiographs were underdiagnosed or under-reported, even when the fractures were severe. Therefore, our goal was to develop a computerized method for detection of vertebral fractures on lateral chest radiographs in order to assist radiologists' image interpretation and thus allow the early diagnosis of osteoporosis. The cases used in this study were 20 patients with severe vertebral fractures and 118 patients without fractures, as confirmed by the consensus of two radiologists. Radiologists identified the locations of fractured vertebrae, and they provided morphometric data on the vertebral shape for evaluation of the accuracy of detecting vertebral end plates by computer. In our computerized method, a curved search area, which included a number of vertebral end plates, was first extracted automatically, and was straightened so that vertebral end plates became oriented horizontally. Edge candidates were enhanced by use of a horizontal line-enhancement filter in the straightened image, and a multiple thresholding technique, followed by feature analysis, was used for identification of the vertebral end plates. The height of each vertebra was determined from locations of identified vertebral end plates, and fractured vertebrae were detected by comparison of the measured vertebral height with the expected height. The sensitivity of our computerized method for detection of fracture cases was 95% (19/20), with 1.03 (139/135) false

    To elucidate early adolescent girls' attitudes, thoughts and feelings towards menstruation and their bodies. 309 12-y-old girls answered questionnaires. One part of the questionnaire dealt with thoughts and feelings towards menstruation. The other part dealt with thoughts and feelings towards menstruation and sex and ability to communicate on aspects of womanhood. Postmenarcheal girls were less positive towards menstruation than premenarcheal girls (p = 1 x 10(-6)). Many girls (43%) did not reaffirm the statement "I like my body" and almost one quarter stated being teased for their appearance. Many of the girls claimed that they had been called "cunt" (38%) or "whore" (46%). If called "cunt" or "whore", 17% stated that they felt alone, 76% felt anger and 50% were offended. Mothers were those with whom girls could most easily "chat" about their period. Sixty-seven per cent received information about menstruation from school nurses. Wanting to be an adult and liking that their body develops seem to be associated with a more positive feeling towards menstruation. Furthermore, mothers' timing and ability to communicate attitudes towards menstruation and the body are as important as those in a girl's immediate environment.

    Longitudinal data are used to examine whether effects of early child care are amplified and/or attenuated by later parenting. Analyses tested these interactions using parenting as both a categorical and continuous variable to balance power and flexibility in testing moderation. The most consistent finding was that maternal sensitivity during adolescence accentuated the association between child care quality and adolescent academic-cognitive skills at age 15 years when maternal sensitivity during adolescence was high. This interaction was obtained in analyses with maternal sensitivity as both a categorical and continuous variable. Relations between early child care hours and adolescent behavioral outcomes also were moderated by maternal sensitivity, with longer child care hours predicting more impulsivity and externalizing at age 15 when maternal sensitivity during middle childhood, scored as a categorical variable, was low to moderate and when maternal sensitivity during adolescence, scored as a continuous variable, was lower. These findings suggest that some child care effects are moderated by subsequent parenting and that this moderation may take both linear and nonlinear forms. PMID:23937381

The aim of this study was to investigate the early results of pediatric appendicitis treatment under the DRG system, focusing on health care expenditure and quality of health care services.Patients and methods: The medical records of 60 patients, 30 patients before (FFS group, and 30 patients after adoption of the DRG system (DRG, were reviewed retrospectively.Results: Mean hospital stay was shortened, but the complication and readmission rates did not worsen in the DRG. Overall health care expenditure and self-payment decreased from Korean Won (KRW 2,499,935 and KRW 985,540, respectively, in the FFS group to KRW 2,386,552 and KRW 492,920, respectively, in the DRG. The insurer’s payment increased from KRW 1,514,395 in the FFS group to KRW 1,893,632 in the DRG. For patients in the DRG, calculation by the DRG system yielded greater overall expenditure (KRW 2,020,209 vs KRW 2,386,552 but lower self-payment (KRW 577,803 vs KRW 492,920 than calculation by the FFS system.Conclusion: The DRG system worked well in pediatric patients with acute appendicitis in terms of cost-effectiveness over the short term. The gradual burden on the national health insurance fund should be taken into consideration.Keywords: appendicitis, child, fee-for-service plans, diagnosis-related groups, quality of health care, health care expenditures

Quanto aos indicadores de adiposidade global ou localizada, não foram observadas diferenças estatísticas entre os grupos. CONCLUSÃO: As diferenças na proporcionalidade corporal não se relacionaram com a estatura. Altos valores de Índice de Cormic parecem estar associados a elevado índice de massa corporal, mas não à composição corporal e à topografia da gordura corporal. Questiona-se, assim, a utilização exclusiva do índice de massa corporal para avaliação antropométrica em serviços de saúde, visto que pode gerar resultados inexatos em populações com comprometimento na proporcionalidade corporal.OBJECTIVE: To verify body proportion performance in pos-menarche adolescents and its influence in anthropometric assessment, emphasizing weight-height ratio.

Anthropometric measurements were obtained according to standardized procedures. Body proportion was assessed by Cormic Index. The population was divided in studied group ( Cormic Index > median and control group ( Cormic Index median, when compared with the control group (37.2%. The overall and localized body fat indicators were not statistically different between the groups. CONCLUSIONS: The differences in body

    When treating dissecting aneurysm of the thoracoabdominal aorta surgically in patients with Marfan syndrome, we have usually performed graft replacement- including the entire thoracoabdominal aorta and reconstruction of all visceral branches, even if dilatation is mild in some segments-to avoid further aortic operations in the follow-up period. From October 1999 through July 2011, 20 consecutive patients with Marfan syndrome underwent repair of dissecting aneurysm of the thoracoabdominal aorta (median age, 45 years; range, 19-65 years). All patients underwent surgical intervention with cerebrospinal fluid (CSF) drainage and distal aortic and selective organ perfusion. Deep hypothermia was used in 13 patients for spinal cord protection. No in-hospital mortality was observed. One patient had temporary spinal cord ischemia but was fully recovered by discharge. Other complications included exploration for bleeding (n=1), prolonged ventilation (n=1), and graft infection (n=1). At a mean follow-up of 54 months (range, 9-129 months), 1 patient had died of interstitial pneumonia at 38 months postoperatively. Survival at 8% years was 91.2±9.0%. Two patients required additional aortic procedures (total arch replacement and aortic valve-sparing surgery). Actuarial rate of freedom from aortic operations at 8 years was 83.9%±10.5%, but no patient needed required repeated thoracotomy for an aortic procedure. Neither false nor patch aneurysms were observed using computed tomography (CT) during follow-up surveillance. Graft replacement for dissecting aneurysm of the thoracoabdominal aorta in Marfan syndrome offers good early and long-term results. We believe total aortic replacement including the entire thoracoabdominal aorta and reconstruction of all visceral arteries should be recommended for selected patients with Marfan syndrome.

    Full Text Available Abstract Background Geographical inaccessibility, lack of transport, and financial burdens are some of the demand side constraints to maternal health services in Uganda, while supply side problems include poor quality services related to unmotivated health workers and inadequate supplies. Most public health interventions in Uganda have addressed only selected supply side issues, and universities have focused their efforts on providing maternal services at tertiary hospitals. To demonstrate how reforms at Makerere University College of Health Sciences (MakCHS can lead to making systemic changes that can improve maternal health services, a demand and supply side strategy was developed by working with local communities and national stakeholders. Methods This quasi-experimental trial is conducted in two districts in Eastern Uganda. The supply side component includes health worker refresher training and additions of minimal drugs and supplies, whereas the demand side component involves vouchers given to pregnant women for motorcycle transport and the payment to service providers for antenatal, delivery, and postnatal care. The trial is ongoing, but early analysis from routine health information systems on the number of services used is presented. Results Motorcyclists in the community organized themselves to accept vouchers in exchange for transport for antenatal care, deliveries and postnatal care, and have become actively involved in ensuring that women obtain care. Increases in antenatal, delivery, and postnatal care were demonstrated, with the number of safe deliveries in the intervention area immediately jumping from Conclusions Transport and service vouchers appear to be a viable strategy for rapidly increasing maternal care. MakCHS can design strategies together with stakeholders using a learning-by-doing approach to take advantage of community resources.

    A common response by plants to fungal attack is deposition of callose, a (1,3)-β-glucan polymer, in the form of cell wall thickenings called papillae, at site of wall penetration. While it has been generally believed that the papillae provide a structural barrier to slow fungal penetration, this idea has been challenged in recent studies of Arabidopsis (Arabidopsis thaliana), where fungal resistance was found to be independent of callose deposition. To the contrary, we show that callose can strongly support penetration resistance when deposited in elevated amounts at early time points of infection. We generated transgenic Arabidopsis lines that express POWDERY MILDEW RESISTANT4 (PMR4), which encodes a stress-induced callose synthase, under the control of the constitutive 35S promoter. In these lines, we detected callose synthase activity that was four times higher than that in wild-type plants 6 h post inoculation with the virulent powdery mildew Golovinomyces cichoracearum. The callose synthase activity was correlated with enlarged callose deposits and the focal accumulation of green fluorescent protein-tagged PMR4 at sites of attempted fungal penetration. We observed similar results from infection studies with the nonadapted powdery mildew Blumeria graminis f. sp. hordei. Haustoria formation was prevented in resistant transgenic lines during both types of powdery mildew infection, and neither the salicylic acid-dependent nor jasmonate-dependent pathways were induced. We present a schematic model that highlights the differences in callose deposition between the resistant transgenic lines and the susceptible wild-type plants during compatible and incompatible interactions between Arabidopsis and powdery mildew.

    Purpose: The following article is a review of 23 years of breast-conserving therapy in our hospital. This study was performed to assess and improve the follow-up care of women with early breast cancer and to evaluate whether or not biannual mammogram is useful. Methods and Materials: Between 1972 and December 1995, 3072 women with pathological size pT1 and pT2 breast cancer were treated with conservative surgery and radiation therapy. Eighty-five patients developed a recurrence in the treated breast as the first site of failure, 12 of which had positive axillary nodes. In the following patient study, those with an noninvasive recurrence were excluded. A retrospective assessment of the entire mammographic course was made, starting with the mammogram at the time of original diagnosis to the mammogram of the recurrence. Results: In our study group the probability for local failure ranged from 1 to 2% per year. At 5 and 10 years the actuarial rates were 5 and 10%. The median time to recurrence was 41 months (range 8-161). Twenty-six (31%) recurrences were detected by mammography alone, 10 (12%) by clinical examination only, and 35 (41%) by both methods. For the patients with an ipsilateral recurrence, the overall actuarial 5- and 10-year survival after treatment was 87 and 70%, respectively. The 5-year actuarial rate of survival from salvage mastectomy was 61%. Conclusion: Considering the high percentage of recurrences detectable by mammography and the possibility of detection within a short-term interval, we think biannual mammographic follow-up is appropriate for the first years following breast-conserving therapy

    Full Text Available Background: Patients with critical lower limb ischemia without patent pedal arteries cannot be treated by the conventional arterial reconstruction. Venous arterialization has been suggested to improve limb salvage in this subgroup of patients but has not gained wide acceptance. We report our early experience after implementing deep and superficial venous arterialization of the lower limb. Materials and methods: Ten patients with critical ischemia and without crural or pedal arteries available for conventional bypass surgery or angioplasty were treated with distal venous arterialization. Inflow was from the most distal unobstructed segment. Run-off was the dorsal pedal venous arch (n=5, the dorsal pedal venous arch and a concomitant vein of the posterior tibial artery (n=3, or the dorsal pedal venous arch and a concomitant vein of the common plantar artery (n=2 depending on the location of the ischemic lesion. Venous valves were destroyed using antegrade valvulotomes, guide wires, knob needles, or retrograde valvulotomes via an extra incision. Results: Seven of the operated limbs were amputated after 23 (1–256 days (median [range]. The main reasons for amputation were lack of healing of either the original wound, of incisional wounds on the foot, or persisting pain at rest. In three cases, the bypass was open at the time of amputation. Two patients experienced complete wound healing after 231 and 342 days, respectively. By the end of follow-up, the last patient was ambulating with slow wound healing but without pain 309 days after surgery. Conclusion: Venous arterialization may be used as a treatment of otherwise unsalveable limbs. The success rate is, however, limited. Technical optimization of the technique is warranted.

    Based on the knowledge of art therapy, we developed a new neuropsychological drawing test in order to identify individuals with mild cognitive impairment (MCI) as well as dementia patients and healthy controls (HC). By observing a variety of drawing characteristics of 92 participants with a mean age of 67.7, art therapy and dementia experts discriminate HC from MCI, early dementia of the Alzheimer-type (eDAT), and moderate dementia of the Alzheimer-type (mDAT) by the process analysis of tree drawings on a digitizing tablet. The art therapist's average categorical rating of healthy and MCI or demented individuals matched the clinical diagnosis by 88%. In a first small study, we analyzed interrater reliability, sensitivity, specificity, negative and positive predicted values of our tree drawing test (TDT) in comparison with the clock drawing test (CDT). Similar values of moderate interrater reliability were found for the TDT (0.56) as well as for the CDT (0.54). A significant high sensitivity of 0.9 within this binary impairment scale (HC versus impaired or demented) can be demonstrated. Substantial values for the specificity (0.67) could be obtained that however remain under a perfect value of the CDT (1.0). Considering 31 individuals that received the clinical diagnosis "impaired or demented" the TDT shows a higher recognition rate for the MCI group than the CDT. Furthermore in 8 of 12 borderline cases of clinical diagnosis, the outcome of the TDT diagnosis was consistent with the final clinical result.

    Objective: To assess the oncologic and cosmetic outcomes for breast cancer patients who underwent breast conservation therapy using Level II oncoplasty techniques. Methods: The prospective, non-randomised and descriptive study was conducted at the Department of Surgery, Unit IV of Civil Hospital, Karachi, from December 2009 to November 2011 in which 21 consecutive women with breast carcinoma who underwent wide local excision with remodeling mammoplasty were enrolled. All patients were reviewed by the surgeon and medical oncologist every 3 months for the first year. A grading system of 5-1 (excellent to poor) was employed and those with 3 or more were considered to have acceptable results. Results: The mean patient age was 45.38+-10.09 years (range: 26-70); 11 (52.3%) were premenopausal and 10 (47.7%) were postmenopausal; and 5 (27.8%) had family history of breast cancer. The mean size of the tumour determined by histology was 59.9+-3.18 mm (range: 25-150). Eight (30%) patients received preoperative chemotherapy to downsize the tumour. Three (14.2%) patients received preoperative radiotherapy. Mean operative time was 1.59+-0.52 hours (range: 1-2.5 hours). Mean volume of breast tissue excised from the breast containing the tumour was 545.27+-412.06 cm3 (range: 43.70-1456). Assessment of excision margins showed no tumour at the margins of 19 (90.4%) patients. Two (9.5%) patients had close but negative margins. The mean hospital stay was 7.10+-3.30 days (range: 4-15). There were early complications in 4 (19%) patients. One (4.76%) patient had late complications. Two (9.5%) patients developed tumour recurrence; both had an ipsilateral tumour recurrence. None of the patients developed metastases and one died of cardiac problem. Twenty (95.2%) patients had an acceptable post-surgical cosmetic result. Conclusion: Level II oncoplasty was a safe option in breast conservation allowing large sized and difficult-location tumour excision with good cosmetic outcome in the study

    Given the challenge of a high proportion of older employees who retire early from work we analyse associations of indicators of a poor psychosocial quality of work with intended premature departure from work in a large sample of older male and female employees in 10 European countries. Baseline data from the 'Survey of Health, Ageing and Retirement in Europe' (SHARE) were obtained from 3523 men and 3318 women in 10 European countries. Data on intended early retirement, four measures of well-being (self-rated health, depressive symptoms, general symptom load, and quality of life), and quality of work (effort-reward imbalance; low control at work) were obtained from structured interviews and questionnaires. Country-specific and total samples are analysed, using logistic regression analysis. Poor quality of work is significantly associated with intended early retirement. After adjustment for well-being odds ratios (OR) of effort-reward imbalance [OR 1.72 (1.43-2.08)] and low control at work [OR 1.51 (1.27-1.80)] on intended early retirement are observed. Poor quality of work and reduced well-being are independently associated with the intention to retire from work. The consistent association of a poor psychosocial quality of work with intended early retirement among older employees across all European countries under study calls for improved investments into better quality of work, in particular increased control and an appropriate balance between efforts spent and rewards received at work.

    Communicative and motor development is frequently found to be associated. In the current study we investigate to what extent communication and motor skills at 1½ years predict skills in the same domains at 3 years of age. This study is based on the Norwegian Mother and Child Cohort Study (MoBa) conducted by the Norwegian Institute of Public Heath. Data stem from 62,944 children and their mothers. Mothers completed questionnaires on their child's communication and motor skills at ages 1½ and 3. Associations between communication and motor skills were estimated in a cross-lagged model with latent variables. Early communication skills were correlated with early motor skills (0.72). Stability was high (0.81) across time points for motor skills and somewhat lower (0.40) for communication skills. Early motor skills predicted later communication skills (0.38) whereas early communication skills negatively predicted later motor skills (-0.14). Our findings provide support for the hypothesis that these two difficulties are not symptoms of separate disorders, but might rather be different manifestations of a common underlying neurodevelopmental weakness. However, there also seem to be specific developmental pathways for each domain. Besides theoretical interest, more knowledge about the relationship between these early skills might shed light upon early intervention strategies and preventive efforts commonly used with children with problems in these areas. Our findings suggest that the relationship between language and motor skills is not likely to be simple and directional but rather to be complex and multifaceted. © 2012 John Wiley & Sons Ltd.

    Background: To evaluate the value of radiotherapy and immediate hormonal therapy in the treatment of stage C prostate cancer. Patients and Method: From 1977 to 1986, 169 patients with clinically stage C prostate cancer underwent irradiation with curative intent following early orchiectomy. Sixty-four patients had a transurethral resection, 22 patients a prostatectomy and 83 patients had only a biopsy. In 38 patients a grade Ia/b tumor was found, in 78 patients a grade IIa/b tumor and in 43 patients a grade IIIa/b tumor using the German grade of malignancy. Treatment fields included the prostate, the seminal vesicles and the locoregional lymphatics. Until 1979 the dose was 60 Gy for the tumor encompassing isodose and from then on 65 Gy with a single dose of 2 Gy. Results: With a median follow-up of 98 months, the overall survival rate for 8 and 10 years was 51% and 37% and the cause-specific survival rate was 84% and 77%, respectively. Thirty-two patients (19%) developed distant metastases. Patients with local tumor control (n=148) had a significantly better overall survival rate of 45% for 10 years compared to patients with clinical local progression of disease (n=21) of 22% (p<0.05). Multivariate analysis showed the grade of malignancy and local control as independent factors for overall survival and cause-specific survival (p<0.05). Twenty-three patients (14%) had at least one late side effect for the rectum or the bladder, in almost all cases grade I or II. Five patients (3%) showed severe late side effects RTOG grade III (n=2) or IV (n=3). One patient had a colostomy, in 2 patients a severe haemorrhagic cystitis was seen. Conclusions: Radiotherapy with photons and early orchiectomy for patients with stage C prostate cancer achieves high local control rates and a 30% to 40% 10-year survival rate with a low incidence of late side effects. The value of the radiotherapy of the locoregional lymphatics remains controversial. (orig.) [Deutsch] Zwischen 1977 und 1986

    To compare immediate versus early (6 weeks) non-occlusal loading of dental implants placed flapless in partially edentulous patients 1 year after loading. Sixty patients were randomised: 30 to the immediately loaded group and 30 to the early loaded group. In order to be immediately loaded, implants were inserted with a minimum torque of > or = 40Ncm. Implants were fully occlusally loaded after 6 months. Outcome measures were prosthesis and implant failures, and biological and biomechanical complications. Five implants in five patients randomised to the immediately loaded group did not reach the required primary implant stability. Three of these implants (two prostheses) were not immediately loaded. Two patients who were randomised to the early loaded group were immediately loaded erroneously. Implants in five patients of the early loaded group were conventionally loaded. No patient dropped out and there were no failures. Two complications occurred in the early and one in the immediately loaded group (no statistically significant difference), but were solved. The use of a flapless technique for placing dental implants in conjunction with non-occlusal immediate or early loading in selected patients can provide excellent clinical results. No differences were observed when comparing implants that were loaded immediately or early. Therefore, when a high primary implant stability is obtained, it might be preferable to load the implants immediately rather than waiting for a few weeks.

    To identify baseline prognostic indicators of disability at 1 year within a contemporary early inflammatory arthritis inception cohort and then develop a clinically useful tool to support early patient education and decision-making. The Scottish Early Rheumatoid Arthritis (SERA) inception cohort is a multicenter, prospective study of patients with newly presenting RA or undifferentiated arthritis. SERA data were analyzed to determine baseline predictors of disability (defined as a Health Assessment Questionnaire [HAQ] score of ≥1) at 1 year. Clinical and psychosocial baseline exposures were entered into a forward stepwise logistic regression model. The model was externally validated using newly accrued SERA data and subsequently converted into a prediction tool. Of the 578 participants (64.5% female), 36.7% (n = 212) reported functional disability at 1 year. Functional disability was independently predicted by baseline disability (odds ratio [OR] 2.67 [95% confidence interval (95% CI) 1.98, 3.59]), depression (OR 2.52 [95% CI 1.18, 5.37]), anxiety (OR 2.37 [95% CI 1.33, 4.21]), being in paid employment with absenteeism during the last week (OR 1.19 [95% CI 0.63, 2.23]), not being in paid employment (OR 2.36 [95% CI 1.38, 4.03]), and being overweight (OR 1.61 [95% CI 1.04, 2.50]). External validation (using 113 newly acquired patients) evidenced good discriminative performance with a C statistic of 0.74, and the calibration slope showed no evidence of model overfit (P = 0.31). In the context of modern early inflammatory arthritis treatment paradigms, predictors of disability at 1 year appear to be dominated by psychosocial rather than more traditional clinical measures. This indicates the potential benefit of early access to nonpharmacologic interventions targeting key psychosocial factors, such as mental health and work disability. © 2016, American College of Rheumatology.

  17. Estimation of the {beta}+ dose to the embryo resulting from {sup 18}F-FDG administration during early pregnancy

    Although {sup 18}F-FDG examinations are widely used, data are lacking on the dose to human embryo tissues in cases of exposure in early pregnancy. Although the photon component can easily be estimated from available data on the pharmacokinetics of {sup 18}F-FDG in female organs and from phantom measurements (considering the uterus as the target organ), the intensity of embryo tissue uptake, which is essential for deriving the {beta}+ dose, is not known. We report the case of a patient who underwent {sup 18}F-FDG PET/CT for tumor surveillance and who was later found to have been pregnant at the time of the examination(embryo age, 8 wk). Methods: The patient received 320 MBq of {sup 18}F-FDG. Imaging started with an unenhanced CT scan 1 h after the injection, followed by PET acquisition. PET images were used to compute the total number of {beta}+ emissions in embryo tissues per unit of injected activity, from standardized uptake value (SUV) measurements corrected for partial-volume effects. A Monte Carlo track structure code was then used to derive the {beta}+ self-dose and the {beta}+ cross-dose from amniotic fluid. The photon and CT doses were added to obtain the final dose received by the embryo. Results: The mean SUV in embryo tissues was 2.7, after correction for the partial-volume effect. The mean corrected SUV of amniotic fluid was 1.1. Monte Carlo simulation showed that the {beta}+ dose to the embryo (self-dose plus cross-dose from amniotic fluid) was 1.8 E-2 mGy per MBq of injected {sup 18}F-FDG. Based on MIRD data for the photon dose to the uterus, the estimated photon dose to the embryo was 1.5 E-2 mGy/MBq. Thus, the specific {sup 18}F-FDG dose to the embryo was 3.3 E-2 mGy/MBq (10.6 mGy in this patient). The CT scan added a further 8.3 mGy. Conclusion: The dose to the embryo is 3.3 E-2 mGy/MBq of {sup 18}F-FDG. The {beta}+ dose contributes 55% of the total dose. This value is higher than previous estimates in late nonhuman-primate pregnancies. (authors)

    To determine how early puberty and peer deviance relate to trajectories of aggressive and delinquent behavior in early adolescence and whether these relationships differ by race/ethnicity. In this longitudinal study, 2607 girls from 3 metropolitan areas and their parents were interviewed at ages 11, 13, and 16 years. Girls reported on their age of onset of menarche, best friend's deviant behavior, delinquency, and physical, relational, and nonphysical aggression. Parents provided information on family sociodemographic characteristics and girls' race/ethnicity. Sixteen percent of girls were classified as early maturers (defined by onset of menarche before age 11 years). Overall, relational and nonphysical aggression increased from age 11 to age 16, whereas delinquency and physical aggression remained stable. Early puberty was associated with elevated delinquency and physical aggression at age 11. The relationship with early puberty diminished over time for physical aggression but not for delinquency. Best friend's deviant behavior was linked with higher levels of all problem behaviors, but the effect lessened over time for most outcomes. Early puberty was associated with a stronger link between best friend's deviance and delinquency, suggesting increased vulnerability to negative peer influences among early-maturing girls. A similar vulnerability was observed for relational and nonphysical aggression among girls in the "other" racial/ethnic minority group only. Early puberty and friends' deviance may increase the risk of problem behavior in young adolescent girls. Although many of these associations dissipate over time, early-maturing girls are at risk of persistently higher delinquency and stronger negative peer influences.

    This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.

    The timing of puberty is a highly polygenic childhood trait that is epidemiologically associated with various adult diseases. Using 1000 Genomes Project-imputed genotype data in up to ∼370,000 women, we identify 389 independent signals (P < 5 × 10 -8 ) for age at menarche, a milestone in female pubertal development. In Icelandic data, these signals explain ∼7.4% of the population variance in age at menarche, corresponding to ∼25% of the estimated heritability. We implicate ∼250 genes via coding variation or associated expression, demonstrating significant enrichment in neural tissues. Rare variants near the imprinted genes MKRN3 and DLK1 were identified, exhibiting large effects when paternally inherited. Mendelian randomization analyses suggest causal inverse associations, independent of body mass index (BMI), between puberty timing and risks for breast and endometrial cancers in women and prostate cancer in men. In aggregate, our findings highlight the complexity of the genetic regulation of puberty timing and support causal links with cancer susceptibility.

  1. Association between menarche and iron deficiency in non-anemic young women.

    Full Text Available The prevalence of iron deficiency (ID among non-pregnant, reproductive-age US women significantly exceeds rates among males. In clinical practice ID screening relies on hemoglobin, a late-stage indicator of ID. As a single, low-cost laboratory test to diagnose ID before anemia develops is lacking, the study objective was to improve ID screening by identifying risk factors among non-anemic, iron-deficient reproductive age women.Cross-sectional data were from the National Health and Nutrition Examination Survey (NHANES 2003-2010. Hemoglobin identified non-anemic women. ID was defined using the body iron formula, requiring ferritin and transferrin receptor values. Logistic regression assessed the association of sociodemographic, behavioral, and reproductive risk factors in an anemia-based conceptual framework with non-anemic reproductive age women (12-49 years with ID, as well as subsets of younger (12-21 years and older (22-49 years women, recognizing that risks may differ by age.Among 6216 women, 494 had ID (prevalence was 8.0%, 95% CI 7.3%, 8.6%. Among non-anemic younger women, 250 (8.7%, 95% CI 7.7%, 9.8% had ID, compared to 244 (7.3%, 95% CI 6.4%, 8.2% older women. Among younger women, menstruation for over 3 years was the only variable significantly associated with non-anemic ID (risk ratio 3.18, 95% CI 2.03, 4.96. No other significant risk factors were identified.Menstrual years was the only risk factor significantly associated with ID among non-anemic younger women. The negative results suggest ID risk factors among non-anemic women may need to be considered separately from those associated with ID anemia.

    runs in real-time by assimilating weather data and uses Monte Carlo simulation techniques to manage the geotechnical and hydrological input parameters. In this context, an assessment of the factors controlling the geotechnical and hydrological features is crucial in order to understand the occurrence of slope instability mechanisms and to provide reliable forecasting of the hydrogeological hazard occurrence, especially in relation to weather events. In particular, the model and the soil characterization were applied in back analysis, in order to assess the reliability of the model through validation of the results with landslide events that occurred during the period. The validation was performed on four past events of intense rainfall that have affected Valle d'Aosta region between 2008 and 2010 years triggering fast shallows landslides. The simulations show substantial improvement of the reliability of the results compared to the use of literature parameters. A statistical analysis of the HIRESSS outputs in terms of failure probability has been carried out in order to define reliable alert levels for regional landslide early warning systems.

    Full Text Available Aim: The study was designed to investigate predictors of effective valve-sparing ascending aortic replacement in patients with Stanford type A aortic dissection combined with aortic insufficiency and to analyze efficacy and safety of this kind of surgery.Methods: From January 2010 to December 2015, 49 patients with Stanford type A aortic dissection combined with aortic insufficiency underwent ascending aortic replacement. All patients were divided into 3 groups: valve-sparing procedures (group 1, n = 11, combined aortic valve and supracoronary ascending aortic replacement (group 2, n = 12, and Bentall procedure (group 3, n = 26. We assessed the initial status of patients, incidence of complications and efficacy of valve-sparing ascending aortic replacement.Results: The hospital mortality rate was 8.2% (4/49 patients. The amount of surgical correction correlated with the initial diameter of the aorta at the level of the sinuses of Valsalva. During the hospital period, none of patients from group 1 developed aortic insufficiency exceeding Grade 2 and the vast majority of patients had trivial aortic regurgitation. The parameters of cardiopulmonary bypass, cross-clamp time and circulatory arrest time did not correlate with the initial size of the ascending aorta and aortic valve blood flow impairment, neither did they influence significantly the incidence and severity of neurological complications. The baseline size of the ascending aorta and degree of aortic regurgitation did not impact the course of the early hospital period.Conclusions: Supracoronary ascending aortic replacement combined with aortic valve repair in ascending aortic dissection and aortic regurgitation is effective and safe. The initial size of the ascending aorta and aortic arch do not influence immediate results. The diameter of the aorta at the level of the sinuses of Valsalva and the condition of aortic valve leaflets could be considered as the limiting factors. Further long

    The tsunamigenic earthquake (M 8.8) that occurred offshore central Chile on 27 February 2010 can be classified as a typical subduction-zone earthquake. The effects of the ensuing tsunami have been devastating along the Chile coasts, and especially between the cities of Valparaiso and Talcahuano, and in the Juan Fernandez islands. The tsunami propagated across the entire Pacific Ocean, hitting with variable intensity almost all the coasts facing the basin. While the far-field propagation was quite well tracked almost in real-time by the warning centres and reasonably well reproduced by the forecast models, the toll of lives and the severity of the damage caused by the tsunami in the near-field occurred with no local alert nor warning and sadly confirms that the protection of the communities placed close to the tsunami sources is still an unresolved problem in the tsunami early warning field. The purpose of this study is two-fold. On one side we perform numerical simulations of the tsunami starting from different earthquake models which we built on the basis of the preliminary seismic parameters (location, magnitude and focal mechanism) made available by the seismological agencies immediately after the event, or retrieved from more detailed and refined studies published online in the following days and weeks. The comparison with the available records of both offshore DART buoys and coastal tide-gauges is used to put some preliminary constraints on the best-fitting fault model. The numerical simulations are performed by means of the finite-difference code UBO-TSUFD, developed and maintained by the Tsunami Research Team of the University of Bologna, Italy, which can solve both the linear and non-linear versions of the shallow-water equations on nested grids. The second purpose of this study is to use the conclusions drawn in the previous part in a tsunami early warning perspective. In the framework of the EU-funded project DEWS (Distant Early Warning System), we will

    The Colorado School of Mines (CSM) has taught its first-semester introductory physics course using a hybrid lecture/Studio Physics format for several years. Over the past year we have converted the second semester of our calculus-based introductory physics course (Physics II) to a Studio Physics format, starting from a traditional lecture-based format. In this paper, we document the early stages of this conversion in order to better understand which features succeed and which do not, and in order to develop a model for switching to Studio that keeps the time and resource investment manageable. We describe the recent history of the Physics II course and of Studio at Mines, discuss the PER-based improvements that we are implementing, and characterize our progress via several metrics, including pre/post Conceptual Survey of Electricity and Magnetism (CSEM) scores, Colorado Learning About Science Survey scores (CLASS), solicited student comments, failure rates, and exam scores.

    Early initiation of antiretroviral treatment (ART) reduces HIV transmission and has health benefits. HIV drug resistance can limit treatment options and compromise use of ART for HIV prevention. We evaluated drug resistance in 85 participants in the HIV Prevention Trials Network 052 trial who started ART at CD4 counts of 350-550 cells per cubic millimeter and failed ART by May 2011; 8.2% had baseline resistance and 35.3% had resistance at ART failure. High baseline viral load and less education were associated with emergence of resistance at ART failure. Resistance at ART failure was observed in 7 of 8 (87.5%) participants who started ART at lower CD4 cell counts.

    To determine whether the simple technique of dynamic gadolinium-enhanced subtraction MR imaging, which is available on standard MR units, can detect ischemia of the femoral head in children with early Legg-Calve-Perthes disease (LCP). Bone perfusion of eight hips in four patients (mean age 7.5 years) was studied using dynamic gadolinium-enhanced substraction MR imaging at the onset of proven LCP (with initial negative plain films). Enhancement of subtracted images was compared with that on standard MR images and with bone scintigraphy findings. Subtraction MR imaging depicted ischemia as a widespread absence of enhancement and was in good agreement with bone scintigraphy. The subtraction technique improved the sensitivity and the specificity of MR imaging in two children. Furthermore, subtraction MR imaging allowed recognition of the pattern of early reperfusion. Our preliminary results indicate that dynamic gadolinium-enhanced subtraction MRI is a simple and promising means of early recognition of ischemia in LCP. (orig.)

    The aim was to evaluate stereotactic body radiation therapy (SBRT) treatment planning variability for early stage nonsmall cell lung cancer (NSCLC) with respect to the published guidelines of the Stereotactic Radiotherapy Working Group of the German Society for Radiation Oncology (DEGRO). Planning computed tomography (CT) scan and the structure sets (planning target volume, PTV; organs at risk, OARs) of 3 patients with early stage NSCLC were sent to 22 radiotherapy departments with SBRT experience: each department was asked to prepare a treatment plan according to the DEGRO guidelines. The prescription dose was 3 fractions of 15 Gy to the 65% isodose. In all, 87 plans were generated: 36 used intensity-modulated arc therapy (IMAT), 21 used three-dimensional conformal radiation therapy (3DCRT), 6 used static field intensity-modulated radiation therapy (SF-IMRT), 9 used helical radiotherapy and 15 used robotic radiosurgery. PTV dose coverage and simultaneously kept OARs doses were within the clinical limits published in the DEGRO guidelines. However, mean PTV dose (mean 58.0 Gy, range 52.8-66.4 Gy) and dose conformity indices (mean 0.75, range 0.60-1.00) varied between institutions and techniques (p ≤ 0.02). OARs doses varied substantially between institutions, but appeared to be technique independent (p = 0.21). All studied treatment techniques are well suited for SBRT of early stage NSCLC according to the DEGRO guidelines. Homogenization of SBRT practice in Germany is possible through the guidelines; however, detailed treatment plan characteristics varied between techniques and institutions and further homogenization is warranted in future studies and recommendations. Optimized treatment planning should always follow the ALARA (as low as reasonably achievable) principle. (orig.)

    BACKGROUND: Cerebral microembolic signals (MES) may predict increased stroke risk in carotid stenosis. However, the relationship between platelet counts or platelet activation status and MES in symptomatic versus asymptomatic carotid stenosis has not been comprehensively assessed. SETTING: University teaching hospitals. METHODS: This prospective, pilot observational study assessed platelet counts and platelet activation status, and the relationship between platelet activation and MES in asymptomatic versus early (≤4 weeks after TIA\\/stroke) and late phase (≥3 months) symptomatic moderate or severe (≥50%) carotid stenosis patients. Full blood count measurements were performed, and whole blood flow cytometry was used to quantify platelet surface activation marker expression (CD62P and CD63) and circulating leucocyte-platelet complexes. Bilateral simultaneous transcranial Doppler ultrasound monitoring of the middle cerebral arteries was performed for 1 hour to classify patients as MES-positive or MES-negative. RESULTS: Data from 31 asymptomatic patients were compared with 46 symptomatic patients in the early phase, and 35 of these patients followed up to the late phase after symptom onset. The median platelet count (211 vs. 200 x 10(9) \\/L; p=0.03) and the median% lymphocyte-platelet complexes were higher in early symptomatic than asymptomatic patients (2.8 vs. 2.4%, p=0.001). The% lymphocyte-platelet complexes was higher in early symptomatic than asymptomatic patients with ≥70% carotid stenosis (p=0.0005), and in symptomatic patients recruited within 7 days of symptom onset (p=0.028). Complete TCD data were available in 25 asymptomatic and 31 early phase symptomatic, and 27 late phase symptomatic patients. 12% of asymptomatic versus 32% of early phase symptomatic (p=0.02) and 19% of late phase symptomatic patients (p=0.2) were MES-positive. Early symptomatic MES-negative patients had a higher% lymphocyte-platelet complexes than asymptomatic MES

    . There were no seroconversions on PrEP and 7 virological failures on early ART among women remaining in the study. Reported adherence to PrEP varied over time between 70% and 85%, whereas over 90% of participants reported taking pills daily while on early ART. Data on provider-side costs were also collected and analysed. The total cost of service delivery was approximately US$126 for PrEP and US$406 for early ART per person-year. The main limitations of this study include the lack of a control group, which was not included due to ethical considerations; clinical study requirements imposed when PrEP was not approved through the regulatory system, which could have affected uptake; and the timing of the implementation of a national sex worker HIV programme, which could have also affected uptake and retention.PrEP and early ART services can be implemented within FSW routine services in high prevalence, urban settings. We observed good uptake for both PrEP and early ART; however, retention rates for PrEP were low. Retention rates for early ART were similar to retention rates for the current standard of care. While the cost of the interventions was higher than previously published, there is potential for cost reduction at scale. The TAPS Demonstration Project results provided the basis for the first government PrEP and early ART guidelines and the rollout of the national sex worker HIV programme in South Africa.

    To study the prognostic impact of baby boomer (BB) generation on survival end-points of patients with early-stage endometrial carcinoma (EC). Data were obtained from the SEER registry between 1988-2009. Inclusion criteria included women who underwent hysterectomy for stage I-II EC. Patients were divided into two birth cohorts: BB (women born between 1946 and 1964) and pre-boomers (PB) (born between 1926 and 1945). A total of 30,956 patients were analyzed. Considering that women in the PB group were older than those of the BB generation, the statistical analysis was limited to women 50-59 years of age at the time of diagnosis (n=11,473). Baby boomers had a significantly higher percentage of endometrioid histology (pgeneration compared to the PB generation (p=0.0003) with a trend for improved uterine cancer-specific survival (p=0.0752). On multivariate analysis, birth cohort (BB vs. PB) was not a significant predictor of survival end-points. Factors predictive of survival included: tumor grade, FIGO stage, African-American race, and increased number of dissected LN. Our study suggests that the survival of BB women between 50-60 years of age is better compared to women in the PB generation. As more BB patients are diagnosed with EC, further research is warranted.

    The timing of puberty is a highly polygenic childhood trait that is epidemiologically associated with various adult diseases. Using 1000 Genomes Project-imputed genotype data in up to ∼370,000 women, we identify 389 independent signals (P ... pubertal development. In Icelandic data, these signals explain ∼7.4% of the population variance in age at menarche, corresponding to ∼25% of the estimated heritability. We implicate ∼250 genes via coding variation or associated expression, demonstrating significant enrichment in neural tissues. Rare...... variants near the imprinted genes MKRN3 and DLK1 were identified, exhibiting large effects when paternally inherited. Mendelian randomization analyses suggest causal inverse associations, independent of body mass index (BMI), between puberty timing and risks for breast and endometrial cancers in women...

    Gastric cancer is the most common malignancy in South America and East Asia. In addition to the high mortality, in Colombia a great disvantage is the lack of data regarding premalignant lesions and early cancer. Aim: To evaluate the usefulness of systematic chromoendoscopy in the prevalence of early cancer and gastric premalignant lesions. A total of 950 were invited to participate, 800 fulfilled the inclusion criteria and finally 650 were analyzed. Results: None of participants had normal gastric mucosa. Mild antrum gastritis was found in 21.8% (142/650), meanwhile moderate or severe antrum gastritis in 77.4% (508/650). Atrophy and metaplasia was found in 14.5% (94/650) and 15.5% (101/650) respectively. H Pilory infection was found in 7.3%, 79.3% 75.5% 57.4% y 0% of subjects with mild, moderate and severe, atrophy, metaplasia and dysplasia respectively. Gastric premalignant lesion was found in 30% (195/650). Two subjects were diagnosed as early gastric cancer and treated by endoscopic submucosal dissection (ESD) with curability as final result. Conclusions: By systematic chromoendoscopy this series has demonstrated that 1/325 healthy volunteers had early gastric cancer and that 1/33 had a premalignant lesion explaining in part the high prevalence of gastric cancer in the region. Bases on this series, gastric cancer is diagnosable and curable among healthy volunteers in Colombia.

  17. Impact of early life adversity on reward processing in young adults: EEG-fMRI results from a prospective study over 25 years.

    Full Text Available Several lines of evidence have implicated the mesolimbic dopamine reward pathway in altered brain function resulting from exposure to early adversity. The present study examined the impact of early life adversity on different stages of neuronal reward processing later in life and their association with a related behavioral phenotype, i.e. attention deficit/hyperactivity disorder (ADHD. 162 healthy young adults (mean age = 24.4 years; 58% female from an epidemiological cohort study followed since birth participated in a simultaneous EEG-fMRI study using a monetary incentive delay task. Early life adversity according to an early family adversity index (EFA and lifetime ADHD symptoms were assessed using standardized parent interviews conducted at the offspring's age of 3 months and between 2 and 15 years, respectively. fMRI region-of-interest analysis revealed a significant effect of EFA during reward anticipation in reward-related areas (i.e. ventral striatum, putamen, thalamus, indicating decreased activation when EFA increased. EEG analysis demonstrated a similar effect for the contingent negative variation (CNV, with the CNV decreasing with the level of EFA. In contrast, during reward delivery, activation of the bilateral insula, right pallidum and bilateral putamen increased with EFA. There was a significant association of lifetime ADHD symptoms with lower activation in the left ventral striatum during reward anticipation and higher activation in the right insula during reward delivery. The present findings indicate a differential long-term impact of early life adversity on reward processing, implicating hyporesponsiveness during reward anticipation and hyperresponsiveness when receiving a reward. Moreover, a similar activation pattern related to lifetime ADHD suggests that the impact of early life stress on ADHD may possibly be mediated by a dysfunctional reward pathway.

    Effective menstrual hygiene has direct and indirect effect on achieving millennium development goals two (universal education), three (gender equality and women empowerment) and, five (improving maternal health). However, in Ethiopiait is an issue which is insufficiently acknowledged in the reproductive health sector. The objective of this study therefore, is to assess the age of menarche and knowledge of adolescents about menstrual hygiene management in Amhara province. School based cross sectional study was conducted from November 2012 to June 2013. Multistage stage sampling technique was used. The school was first clustered in to grades & sections and thenparticipants were selected by lottery method. A pretested &structured questionnaire was used. Data were entered, cleaned and analyzed using SPSS version 16.0. Finally, multivariate analysis was used to assess independent effect of predictors. In this study, 492 students were included, making a response rate of 100%. Mean age at menarche was 14.1±1.4 years. The main sources of information about menstrual hygiene management were teachers for 212 (43.1%). Four hundred forty six (90.7%) respondents had high level knowledge about menstrual hygiene management. Most of the respondents 457 (92.9%) and 475 (96.5%) had access for water and toilet facility respectively. Place of residence (AOR = 1.8, 95%CI: [1.42-1.52]) and educational status of their mothers' (AOR = 95%CI: [1.15-13.95]) were independent predictors of knowledge about menstrual hygiene management. Knowledge of respondents about menstrual hygiene management was very high. School teachers were the primary source of information. Place of residence and their mother's educational status were independent predictors of menstrual hygiene management. Thus, the government of Ethiopia in collaboration with its stalk holders should develop and disseminatereproductive health programmes on menstrual hygiene management targeting both parents and their

    Geographical inaccessibility, lack of transport, and financial burdens are some of the demand side constraints to maternal health services in Uganda, while supply side problems include poor quality services related to unmotivated health workers and inadequate supplies. Most public health interventions in Uganda have addressed only selected supply side issues, and universities have focused their efforts on providing maternal services at tertiary hospitals. To demonstrate how reforms at Makerere University College of Health Sciences (MakCHS) can lead to making systemic changes that can improve maternal health services, a demand and supply side strategy was developed by working with local communities and national stakeholders. This quasi-experimental trial is conducted in two districts in Eastern Uganda. The supply side component includes health worker refresher training and additions of minimal drugs and supplies, whereas the demand side component involves vouchers given to pregnant women for motorcycle transport and the payment to service providers for antenatal, delivery, and postnatal care. The trial is ongoing, but early analysis from routine health information systems on the number of services used is presented. Motorcyclists in the community organized themselves to accept vouchers in exchange for transport for antenatal care, deliveries and postnatal care, and have become actively involved in ensuring that women obtain care. Increases in antenatal, delivery, and postnatal care were demonstrated, with the number of safe deliveries in the intervention area immediately jumping from Voucher revenues have been used to obtain needed supplies to improve quality and to pay health workers, ensuring their availability at a time when workloads are increasing. Transport and service vouchers appear to be a viable strategy for rapidly increasing maternal care. MakCHS can design strategies together with stakeholders using a learning-by-doing approach to take advantage of

    The aim of this study was to compare the morbidity and short-term efficacy of retro-pubic (TVT) and inside-out trans-obturator (TVT-O) sub-urethral sling in the treatment of stress urinary incontinence. This was a prospective multi-centre randomised trial; 231 women with primary stress urinary incontinence were randomised to TVT (114) or TVT-O (117). The International Consultation on Incontinence-Short Form (ICIQ-SF), Women Irritative Prostate Symptoms Score (W-IPSS) and Patient Global Impression of Severity (PGI-S) questionnaires were used to evaluate the impact of incontinence and voiding dysfunction on QoL and to measure the patient's perception of incontinence severity. The primary and secondary outcome measures were rates of success and complications. The SPSS software was used for data analysis. The TVT-O procedure was associated with significantly shorter operation time and with a more extensive use of general anaesthesia when compared with TVT. There were 5 (4%) bladder perforations in the TVT group compared with none in the TVT-O group. Rates of early post-operative urinary retention and voiding difficulty were similar for both groups and no difference was found in the average hospital stay. Six patients (5%) in the TVT-O group complained of thigh pain in the post-operative course. The median follow-up time was 6 months. Two hundred eighteen patients were available for the analysis of outcomes. Subjective and objective cure rates were 92% and 92% in the TVT group and 87% and 89% in the TVT-O group. The ICIQ-SF questionnaire symptoms score showed a highly statistical decrease in both groups, the W-IPSS on the contrary was unchanged. Our data show that both procedures were equally effective in the short-term for the treatment of stress urinary incontinence with a highly significant improvement in incontinence-related QoL.

    determine the sexual hormones levels and to establish the influence of this entity on the menarche age. METHODS: a cross-sectional descriptive study was conducted in 74 women aged 15 and 35, all seen in the Diabetes Care Center of Ciudad de La Habana, Cuba, which were distributed in two groups: A and B, both with n= 37; A: diagnosed with diabetes before the menarche appearance and B; after it. We designed a questionnaire of general data and puberal and menstrual medical records; we determined the presence of fasting glycemia, glycosylated hemoglobin and sexual hormones; both groups were compared using the t Student and chi² tests. RESULTS: we achieved a high frequency of dysmenorrhea, menorrhhea and premenstrual tension, as well the loss of a correlation among some sexual hormones. Earlier presence of type 1 diabetes mellitus determined a greater age of menarche, lower levels of gonadotropins (LH and FSH and oligomenorrhea. CONCLUSIONS: type 1 diabetes mellitus diagnosed before menarche seems to interfere with maturation and subsequent function of female gonadal axis, which conditioned a greater frequency of dysmenorrhea and menstrual irregularities.

    caffeine remained associated with reduced odds of developing AKI (adjusted odds ratio, 0.20; 95% CI, 0.11-0.34), indicating that for every 4.3 neonates exposed to caffeine one case of AKI was prevented. Among neonates with early AKI, those receiving caffeine were less likely to develop stage 2 or 3 AKI (adjusted odds ratio, 0.20; 95% CI, 0.12-0.34). Caffeine administration in preterm neonates is associated with reduced incidence and severity of AKI. Further studies should focus on the timing and dosage of caffeine to optimize the prevention of AKI.

    We sought to assess physician interest in molecular prognosic testing for patients with early stage colon cancer, and identify factors associated with the likelihood of test adoption. We identified physicians who care for patients with early-stage (pN0) colon cancer patients, mailed them a survey, and analyzed survey responses to assess clinician receptivity to the use of a new molecular test (GUCY2C) that identifies patients at risk for recurrence, and clinician readiness to act on abnormal test results. Of 104 eligible potential respondents, 41 completed and returned the survey. Among responding physicians, 56 % were receptive to using the new prognostic test. Multivariable analyses showed that physicians in academic medical centers were significantly more receptive to molecular test use than those in non-academic settings. Forty-one percent of respondents were ready to act on abnormal molecular test results. Physicians who viewed current staging methods as inaccurate and were confident in their capacity to incorporate molecular testing in practice were more likely to say they would act on abnormal test results. Physician receptivity to molecular diagnostic testing for early-stage colon cancer patients is likely to be influenced by practice setting and perceptions related to delivering quality care to patients.

    This research project evaluates post-retrofit performance measurements, energy use data and construction costs for 13 projects that participated in the National Grid Deep Energy Retrofit Pilot program. The projects implemented a package of measures defined by performance targets for building enclosure components and building enclosure air tightness. Nearly all of the homes reached a post-retrofit air tightness result of 1.5 ACH 50. Homes that used the chainsaw retrofit technique along with roof insulation, and wall insulation applied to the exterior had the best air tightness results and the lowest heating and cooling source energy use. Analysis of measure costs and project objectives yielded a categorization of costs relative to energy performance objectives. On average about 1/2 of the energy-related measure costs correspond primarily to energy-related objectives, and 20% of energy-related measure costs relate primarily to non-energy objectives.

    A case of slight renal tubular dysfunction associated with cataract and anaemia was diagnosed in a 3-month-old black boy in whom high levels of mercury were found in blood and urine. Several arguments suggest that the renal, ocular and haematological defects may have resulted from exposure to mercury during foetal life and the 1-month lactation period due to the extensive use of inorganic mercury containing cosmetics by the mother.

    PurposeThe major complication occurring with biliary stents is stent occlusion, frequently seen because of tumour in-growth, epithelial hyperplasia, and sludge deposits, resulting in recurrent jaundice and cholangitis. We report a prospective study with the results of first in man percutaneous intraductal radiofrequency (RF) ablation to clear the blocked metal stents in patients with malignant biliary obstruction using a novel bipolar RF catheter.MethodsNine patients with malignant biliary obstruction and blocked metal stents were included. These patients underwent intraductal biliary RF ablation through the blocked metal stent following external biliary decompression with an internal–external biliary drainage.ResultsAll nine patients had their stent patency restored successfully without the use of secondary stents. Following this intervention, there was no 30-day mortality, haemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the nine patients, six are alive and three patients are dead with a median follow-up of 122 (range 50–488) days and a median stent patency of 102.5 (range 50–321) days. Six patients had their stent patent at the time of last follow-up or death. Three patients with stent blockage at 321, 290, and 65 days postprocedure underwent percutaneous transhepatic drain insertion and repeat ablation.ConclusionsIn this selective group of patients, it appears that this new approach is safe and feasible. Efficacy remains to be proven in future, randomized, prospective studies.

    In an attempt to replicate the findings of Smith et al., seeds of Raphanus sativus L. (radish), Sinapsis alba L. (mustard), and Hordeum vulgare L. (barley) were grown for between 9 and 21 days in continuous electromagnetic fields (EMFs) at ion-cyclotron resonance conditions for stimulation of Ca{sup 2+} (B{sub H} = 78.3 {micro}T, B{sub HAC} = 40 {micro}T peak-peak at 60 Hz, B{sub v} = 0). On harvesting, radish showed results similar to those of Smith et al. Dry stem weight and plant height were both significantly greater (Mann-Whitney tests, Ps < 0.05) in EMF-exposed plants than in control plants in each EMF experiment. Wet root weight was significantly greater in EMF-exposed plants in two out of three experiments, as were dry leaf weight, dry whole weight, and stem diameter. Dry root weight, wet leaf weight, and wet whole weight were significantly greater in EMF-exposed plants in one of three experiments. All significant differences indicated an increase in weight or size in the EMF-exposed plants. In each of the sham experiments, no differences between exposed and control plants were evident. Mustard plants failed to respond to the EMFs in any of the plant parameters measured. In one experiment, barley similarly failed to respond; but in another showed significantly greater wet root weight and significantly smaller stem diameter and dry seed weight at the end of the experiment in exposed plants compared to control plants. Although these results give no clue about the underlying bioelectromagnetic mechanism, they demonstrate that, at least for one EMF-sensitive biosystem, results can be independently replicated in another laboratory. Such replication is crucial in establishing the validity of bioelectromagnetic science.

  12. Early malnutrition results in long-lasting impairments in pattern-separation for overlapping novel object and novel location memories and reduced hippocampal neurogenesis.

    Numerous epidemiological studies indicate that malnutrition during in utero development and/or childhood induces long-lasting learning disabilities and enhanced susceptibility to develop psychiatric disorders. However, animal studies aimed to address this question have yielded inconsistent results due to the use of learning tasks involving negative or positive reinforces that interfere with the enduring changes in emotional reactivity and motivation produced by in utero and neonatal malnutrition. Consequently, the mechanisms underlying the learning deficits associated with malnutrition in early life remain unknown. Here we implemented a behavioural paradigm based on the combination of the novel object recognition and the novel object location tasks to define the impact of early protein-restriction on the behavioural, cellular and molecular basis of memory processing. Adult rats born to dams fed a low-protein diet during pregnancy and lactation, exhibited impaired encoding and consolidation of memory resulting from impaired pattern separation. This learning deficit was associated with reduced production of newly born hippocampal neurons and down regulation of BDNF gene expression. These data sustain the existence of a causal relationship between early malnutrition and impaired learning in adulthood and show that decreased adult neurogenesis is associated to the cognitive deficits induced by childhood exposure to poor nutrition.

    Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long-term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation. Patients with a history of long-term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long-term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals.

    Purpose: Aim was to determine immediate results and mid-term outcome of the hemoparin-coated (HC) stainless-steel stent (camouflage coating) in the treatment of occlusive lesions of the iliac arteries. Materials and methods: Twenty-eight patients were prospectively treated with the use of a HC stent between January 2007 and March 2010. Clinical examination and color-doppler ultrasound were performed at 1, 3, 6 and 12 months, CT angiography (CTA) or MR angiography (MRA) at 12 months. Indication for treatment was a high-grade stenosis of the common iliac and/or external iliac artery. Results: Successful placement was achieved in all patients. Significant decrease in translesional pressure gradient (>10 mmHg) was measured in 27 patients (96%). In one patient, proximal dissection occurred without flow limitation. A minor complication (small access site hematoma) occurred in one patient (4%). Two patients (7%) were lost to follow-up. After 12 months, stent patency in CTA, MRA and ultrasound was 100%. 20 patients (77%) experienced an initial improvement of at least one clinical stage. In one patient (4%), mild intimal hyperplasia without significant stenosis was observed. In three patients (12%), proximal or distal stenosis occurred. A non-significant increase of mean ankle-brachial index (ABI) after treatment was measured (0.85 ± 0.27 vs. 0.75 ± 0.22, respectively; p = 0.328). Conclusions: The use of HC stents in patients with iliac artery occlusive disease may lead to a lower rate of intimal hyperplasia and thus to increased patency rates even in heavily calcified vessels. However, large-scale prospective trials have to be performed to evaluate the long-term patency rates of the HC coated stents.

    Full Text Available The use of RT-qPCR provides a powerful tool for gene expression studies; however, the proper interpretation of the obtained data is crucially dependent on accurate normalization based on stable reference genes. Recently, strong evidence has been shown indicating that the expression of many commonly used reference genes may vary significantly due to diverse experimental conditions. The isolation of pancreatic islets is a complicated procedure which creates severe mechanical and metabolic stress leading possibly to cellular damage and alteration of gene expression. Despite of this, freshly isolated islets frequently serve as a control in various gene expression and intervention studies. The aim of our study was to determine expression of 16 candidate reference genes and one gene of interest (F3 in isolated rat pancreatic islets during short-term cultivation in order to find a suitable endogenous control for gene expression studies. We compared the expression stability of the most commonly used reference genes and evaluated the reliability of relative and absolute quantification using RT-qPCR during 0-120 hrs after isolation. In freshly isolated islets, the expression of all tested genes was markedly depressed and it increased several times throughout the first 48 hrs of cultivation. We observed significant variability among samples at 0 and 24 hrs but substantial stabilization from 48 hrs onwards. During the first 48 hrs, relative quantification failed to reflect the real changes in respective mRNA concentrations while in the interval 48-120 hrs, the relative expression generally paralleled the results determined by absolute quantification. Thus, our data call into question the suitability of relative quantification for gene expression analysis in pancreatic islets during the first 48 hrs of cultivation, as the results may be significantly affected by unstable expression of reference genes. However, this method could provide reliable information

    Purpose: Aim was to determine immediate results and mid-term outcome of the hemoparin-coated (HC) stainless-steel stent (camouflage coating) in the treatment of occlusive lesions of the iliac arteries. Materials and methods: Twenty-eight patients were prospectively treated with the use of a HC stent between January 2007 and March 2010. Clinical examination and color-doppler ultrasound were performed at 1, 3, 6 and 12 months, CT angiography (CTA) or MR angiography (MRA) at 12 months. Indication for treatment was a high-grade stenosis of the common iliac and/or external iliac artery. Results: Successful placement was achieved in all patients. Significant decrease in translesional pressure gradient (>10 mmHg) was measured in 27 patients (96%). In one patient, proximal dissection occurred without flow limitation. A minor complication (small access site hematoma) occurred in one patient (4%). Two patients (7%) were lost to follow-up. After 12 months, stent patency in CTA, MRA and ultrasound was 100%. 20 patients (77%) experienced an initial improvement of at least one clinical stage. In one patient (4%), mild intimal hyperplasia without significant stenosis was observed. In three patients (12%), proximal or distal stenosis occurred. A non-significant increase of mean ankle-brachial index (ABI) after treatment was measured (0.85 ± 0.27 vs. 0.75 ± 0.22, respectively; p = 0.328). Conclusions: The use of HC stents in patients with iliac artery occlusive disease may lead to a lower rate of intimal hyperplasia and thus to increased patency rates even in heavily calcified vessels. However, large-scale prospective trials have to be performed to evaluate the long-term patency rates of the HC coated stents

    Full Text Available PurposeThe rationale for hypofractionated radiotherapy in the treatment of prostate cancer is based on the modern understanding of radiobiology and advances in stereotactic body radiotherapy (SBRT techniques. Whole-pelvis irradiation combined with SBRT boost for high-risk prostate cancer might escalate biologically effective dose without increasing toxicity. Here, we report our 4-year results of SBRT boost for high-risk localized prostate cancer.Methods and MaterialsFrom October 2009 to August 2012, 41 patients of newly diagnosed, high-risk or very high-risk (NCCN definition localized prostate cancer patients were treated with whole-pelvis irradiation and SBRT boost. The whole pelvis dose was 45Gy (25 fractions of 1.8Gy. The SBRT boost dose was 21 Gy (three fractions of 7 Gy. Ninety percent of these patients received hormone therapy. The toxicities of gastrointestinal (GI and genitourinary (GU tracts were scored by Common Toxicity Criteria Adverse Effect (CTCAE v3.0. Biochemical failure was defined by Phoenix definition.ResultsMedian follow-up was 42 months. Mean PSA before treatment was 44.18 ng/ml. Mean PSA level at 3, 6, 12, 18, and 24 months was 0.94, 0.44, 0.13, 0.12, and 0.05 ng/ml, respectively. The estimated 4-year biochemical failure-free survival was 91.9%. Three biochemical failures were observed. GI and GU tract toxicities were minimal. No grade 3 acute GU or GI toxicity was noted. During radiation therapy, 27% of the patient had grade 2 acute GU toxicity and 12% had grade 2 acute GI toxicity. At 3 months, most toxicity scores had returned to baseline. At the last follow up, there was no grade 3 late GU or GI toxicity.ConclusionsWhole-pelvis irradiation combined with SBRT boost for high-risk localized prostate cancer is feasible with minimal toxicity and encouraging biochemical failure-free survival. Continued accrual and follow-up would be necessary to confirm the biochemical control rate and the toxicity profiles.

    Purpose: To develop methods of predicting the pulmonary consequences of thoracic irradiation (RT) by prospectively studying changes in pulmonary function following RT. Methods: 105 patients receiving incidental partial lung irradiation during treatment of tumors in/around the thorax (lung-70, breast-18, lymphoma-4, misc-3) had whole lung function assessed (symptoms and pulmonary function tests [PFTs: FEV1-forced expiratory volume 1 sec; DLCO-diffusion capacity]) before and repeatedly 6-48 months following RT. All had computed tomography-based 3-dimensional (3D) dose calculations with lung density heterogeneity corrections for dose-volume histogram (DVH) and NTCP (normal tissue complication probability) calculations. Functional DVHs (DVfH) based on SPECT (single photon emission computed tomography) lung perfusion scans, and serial transforming growth factor-beta (TGF-β) levels were available in 50 and 30 patients, respectively. The incidence and severity of changes in whole lung function were correlated with clinical, physical and biological factors outlined in the results. Exploratory statistical analyses were preformed using chi-square, logistic regression, and multiple linear regression. Mean pt age=57, range 21-87; sex: 63 F, 42 M; 29 had chemotherapy (CT) before/with RT; Follow-up 6-48 months (mean 15, median 12). Results RT-induced symptoms developed in 26 patients (7-grade I-no intervention; 16 grade II-steroids; 3 grade III-oxygen and steroids). A mixed model based on pre-RT DLCO and CT-based NTCP was strongly predictive for the development of symptoms (p 30 Gy. In patients with 'good' pre-RT PFTs, there may be a relationship between the % reduction in PFT and % lung volume receiving >30 Gy (figure). Conclusion: Whole lung injury (symptoms or PFT changes) appears to be related to a variety of physical, biological and clinical factors. The data suggest that no one variable is likely to be an adequate predictor and that multi-faceted predictive models will be

    Background The endovascular approach became an alternative to open surgical treatment of popliteal artery aneurysm over the last few years. Heparin-bonded stent-grafts have been employed for endovascular popliteal artery aneurysm repair, showing good and stable results. Only few reports about the use of multilayer flow modulator are available in literature, providing small patient series and short follow-up. The aim of this study is to report the outcomes of patients with popliteal artery aneurysm treated with the multilayer flow modulator in three Italian centres. Methods We retrospectively analysed a series of both symptomatic and asymptomatic patients with popliteal artery aneurysm treated with the multilayer flow modulator from 2009 to 2015. Follow-up was undertaken with clinical and contrast-enhanced ultrasound examinations at 1, 6 and 12 months, and yearly thereafter. Computed tomography angiography was performed in selected cases. Primary endpoints were aneurysm sac thrombosis; freedom from sac enlargement and primary, primary-assisted and secondary patency during follow-up. Secondary endpoints were technical success, collateral vessels patency, limb salvage and aneurysm-related complications. Results Twenty-three consecutive patients (19 males, age 72 ± 11) with 25 popliteal artery aneurysms (mean diameter 23 mm ± 1, 3 symptomatic patients) were treated with 40 multilayer flow modulators during the period of the study. Median follow-up was 22.6 ± 16.7 months. Complete aneurysm thrombosis occurred in 92.9% of cases (23/25 cases) at 18 months. Freedom from sac enlargement was 100% (25/25 cases) with 17 cases of aneurysm sac shrinkage (68%). At 1, 6, 12 and 24 months, estimated primary patency was 95.7%, 87.3%, 77% and 70.1%, respectively. At the same intervals, primary-assisted patency was 95.7%, 91.3%, 86% and 86%, respectively, and secondary patency was 100%, 95.7%, 90.3% and 90.3%, respectively. Technical success was 100%. The collateral

    There is controversy concerning the management of the remaining cavity after the evacuation of a cyst in patients who have undergone surgical operation for liver hydatidosis. This study compares the results of capitonnage and tube drainage of the remaining cavity. In this retrospective study, participants were selected from two groups of patients with a liver hydatid cyst who underwent capitonnage or tube d
