Full Text Available BACKGROUND Menstruation is a natural physiological process linked with several misconceptions and practices having crucial role for health and dignity of girls and women. Hygiene-related practices increases vulnerability to reproductive tract infections. Adolescent girls dwelling in slums are vulnerable to poor reproductive health due to lack of awareness about reproductive health. Keeping in view the above, study has been undertaken with the following aim and objective. The aim of the study is to assess the menstrual hygiene practices and reproductive tract infection among slum dwelling adolescent girls aged 15-19 years. MATERIALS AND METHODS A community-based cross-sectional study was conducted for 1 year from June 2014 to May 2015 covering 210 adolescent girls aged 15-19 years living in the slums of Dibrugarh Town, Assam. An interview using a predesigned and pretested format conducted by house to house survey. For analysis, mean, standard deviation and proportions were calculated, Chi-square and Fischer’s exact test was done to see the association. RESULTS Mean age of girls was (16.57 ± 1.48 years and mean age of menarche was (12.73 ± 1.44 years. Awareness about menstruation was 27.1% prior to attainment of menarche. Rate of sanitary napkins use was 68.6% and 53.2% girls cleaned external genitalia >2 times per day. Regarding cultural practices of restriction, 100% girls did not attend any religious occasions during menstruation. Prevalence of reproductive tract infection was 43.3%, which was significantly more among girls using homemade reusable pad and washing external genitalia ≤2 times per day during menstruation. CONCLUSION There is a need to improve menstrual hygiene practices amongst adolescent girls. Awareness building on menstrual hygiene and other factors like traditional beliefs and practices needs to be addressed.

Full Text Available Two feeding trials were conducted to determine the optimum feeding frequency in growing Korean rockfish, (Sebastes schlegeli reared at the temperatures of 15°C and 19°C. Fish averaging 92.2±0.7 g (mean±standard deviation [SD] at 15.0±0.5°C and 100.2±0.4 g (mean±SD at 19.0±0.5°C water temperature were randomly distributed into each of 15 indoor tanks containing 250-L sea water from a semi-recirculation system. A total of five feeding frequency groups were set up in three replicates as follows: one meal in a day at 08:00 hour, two meals a day at 08:00 and 17:00 hours, three meals a day at 08:00, 14:00, and 20:00 hours, four meals a day at 08:00, 12:00, 16:00, and 20:00 hours, and one meal every 2 days at 08:00 hour. Fish were fed at the rate of 1.2% body weight (BW/d at 15°C and 1.5% BW/d at 19°C. At the end of 8 wks of feeding trial weight gain and specific growth rate were significantly higher at the fish fed groups of one meal a day and two meals a day at 15°C and fish fed groups of 1 meal every 2 days at 19°C were significantly lower than those of all other fish fed groups. Glutamic oxaloacetic transaminase and glutamic pyruvic transaminase of fish fed group at 1 meal every 2 days was significantly higher than those of all other fish fed groups in both experiments. Weight gain, specific growth rate and condition factor were gradually decreased as the feeding frequency increased. The results indicate that growing Korean rockfish 92 and 100 g perform better at 15°C than 19°C water temperature. As we expected, current results have indicated that a feeding frequency of 1 meal a day is optimal for the improvement of weight gain in growing Korean rockfish grown from 92 g to 133 g at 15°C and 100 g to 132 g at 19°C water temperature.

Thakrar, Ashish P; Forrest, Alexandra D; Maltenfort, Mitchell G; Forrest, Christopher B

2018-01-01

The United States has poorer child health outcomes than other wealthy nations despite greater per capita spending on health care for children. To better understand this phenomenon, we examined mortality trends for the US and nineteen comparator nations in the Organization for Economic Cooperation and Development for children ages 0-19 from 1961 to 2010 using publicly available data. While child mortality progressively declined across all countries, mortality in the US has been higher than in peer nations since the 1980s. From 2001 to 2010 the risk of death in the US was 76 percent greater for infants and 57 percent greater for children ages 1-19. During this decade, children ages 15-19 were eighty-two times more likely to die from gun homicide in the US. Over the fifty-year study period, the lagging US performance amounted to over 600,000 excess deaths. Policy interventions should focus on infants and on children ages 15-19, the two age groups with the greatest disparities, by addressing perinatal causes of death, automobile accidents, and assaults by firearm.

Although within Latin America Chile has one of the lowest birth rates among adolescents, it has a high rate in comparison to other developed nations. To explore trends in birth rates among adolescents by selected demographics in Chile. The national trend in birth rates was examined for women aged 15-19 years between 1992 and 2012. The birth rates for regions and communes were calculated using birth and census data and were analysed to determine its relationship to the regional or communal poverty rate, which were obtained from the Casen Survey. Differences in educational attainment were explored among adolescents with first-order and second-order or higher births using the Chi-square test. The birth rate among adolescents has experienced a 25% decline in the past 20 years. Cross-regional variance in birth rates could not be explained by poverty rates. Within the Metropolitan Region, there is a positive correlation between poverty and adolescent birth rates. Among adolescents giving birth, 67% had completed 10-12 years of school at birth, but there is a significant difference in educational attainment between girls with a first-order and those with a higher-order birth. In Chile, the adolescent birth rate varies greatly among regions and communes. This study found that urban and wealthy areas had lower birth rates than poor and rural ones, and that girls with a first-order birth had completed more years of school than girls with higher-order births. © Faculty of Sexual and Reproductive Healthcare of the Royal College of Obstetricians and Gynaecologists (unless otherwise stated in the text of the article) 2017.

Teens who give birth at age 15-17 years are at increased risk for adverse medical and social outcomes of teen pregnancy. To examine trends in the rate and proportion of births to teens aged 15-19 years that were to teens aged 15-17 years, CDC analyzed 1991-2012 National Vital Statistics System data. National Survey of Family Growth (NSFG) data from 2006-2010 were used to examine sexual experience, contraceptive use, and receipt of prevention opportunities among female teens aged 15-17 years. During 1991-2012, the rate of births per 1,000 teens declined from 17.9 to 5.4 for teens aged 15 years, 36.9 to 12.9 for those aged 16 years, and 60.6 to 23.7 for those aged 17 years. In 2012, the birth rate per 1,000 teens aged 15-17 years was higher for Hispanics (25.5), non-Hispanic blacks (21.9), and American Indians/Alaska Natives (17.0) compared with non-Hispanic whites (8.4) and Asians/Pacific Islanders (4.1). The rate also varied by state, ranging from 6.2 per 1,000 teens aged 15-17 years in New Hampshire to 29.0 in the District of Columbia. In 2012, there were 86,423 births to teens aged 15-17 years, accounting for 28% of all births to teens aged 15-19 years. This percentage declined from 36% in 1991 to 28% in 2012 (pteens aged 15-17 years received formal sex education on birth control or how to say no to sex, 24% had not spoken with parents about either topic; among sexually experienced female teens, 83% reported no formal sex education before first sex. Among currently sexually active female teens (those who had sex within 3 months of the survey) aged 15-17 years, 58% used clinical birth control services in the past 12 months, and 92% used contraception at last sex; however, only 1% used the most effective reversible contraceptive methods. Births to teens aged 15-17 years have declined but still account for approximately one quarter of births to teens aged 15-19 years. These data highlight opportunities to increase younger teens exposure to interventions that delay

2008-05-01

Full Text Available Abstract Background Despite the last years of rapid increase in use of wireless phones little data on the use of these devices has been systematically assessed among young persons. The aim of this descriptive cross-sectional study was to assess use of wireless phones and to study such use in relation to explanatory factors and self-reported health symptoms. Methods A postal questionnaire comprising 8 pages of 27 questions with 75 items in total was sent to 2000 Swedish adolescents aged 15–19 years and selected from the population registry using a stratified sampling scheme. Results The questionnaire was answered by 63.5% of the study subjects. Most participants reported access to a mobile phone (99.6% and use increased with age; 55.6% of the 15-year-olds and 82.2% of the 19-year-olds were regular users. Girls generally reported more frequent use than boys. Use of wired hands-free equipment 'anytime' was reported by 17.4%. Cordless phones were used by 81.9%, and 67.3% were regular users. Watching TV increased the odds ratio for use of wireless phones, adjusted for age and gender. Some of the most frequently reported health complaints were tiredness, stress, headache, anxiety, concentration difficulties and sleep disturbances. Regular users of wireless phones had health symptoms more often and reported poorer perceived health than less frequent users. Conclusion Almost all adolescence in this study used a wireless phone, girls more than boys. The most frequent use was seen among the older adolescents, and those who watched TV extensively. The study further showed that perceived health and certain health symptoms seemed to be related to the use of wireless phones. However, this part of the investigation was explorative and should therefore be interpreted with caution since bias and chance findings due to multiple testing might have influenced the results. Potentially this study will stimulate more sophisticated studies that may also investigate

To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007. A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire. Logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (95%CI) by category: no SID, SID at 10-15 years and SID at 16-19 years. The national mean age of SID was 16 years, being 15 years for boys (95%CI: 15.88-16.11) and 16 years for girls (95%CI: 15.26-15.42). Factors associated with SID in boys were disadvantaged socioeconomic level (OR=0.66; 95%CI: 0.46-0.94), living with parents (OR=0.65; 95%CI: 0.56-0.75), less offensive communication between parents and boys/girls (OR=0.66; 95%CI: 0.57-0.77), and high social self-esteem (OR=1.68; 95%CI: 1.35-1.77). Factors associated with SID in girls were traditional gender beliefs (OR=0.49; 95%CI: 0.32-0.74), high depressive symptoms (OR=1.88; 95%CI: 1.19-2.99), and high family self-esteem (OR= 0.50; 95%CI: 0.38-0.65). In Mexico, SID occurred early in boys. In addition, the findings of this study show that in Mexico, the age of SID and associated factors differ in boys and girls. The age of SID is strongly influenced by gender and cultural beliefs. Copyright © 2015 SESPAS. Published by Elsevier Espana. All rights reserved.

Reproductive Tract Infections and Treatment Seeking Behavior among Married Adolescent Women 15-19 Years in India.

Prusty, Ranjan Kumar; Unisa, Sayeed

2013-01-01

India is home to the highest number of adolescents in the world. Adolescents in India suffer from lack of knowledge and empowerment to make informed sexual and reproductive health decisions. This paper analyses the prevalence of reproductive tract infections and sexually transmitted infections (RTI/STI) and treatment seeking behavior among married adolescent women in India aged 15-19 years. Data from the District Level Household Survey (DLHS, 2007-08) of India were used. The prevalence of RTIs symptoms and treatment seeking behavior among women by different socio-demographic characteristics was analyzed. Factor analysis was utilized to create an index using information about 11 symptoms of RTI/STI collected in the survey. Linear and binary logistic regressions were used to know the association between infections and treatment seeking behavior with socio-demographic factors. About 15 percent of adolescent women reported having any symptoms of RTI/STI. The main symptoms reported were low backache, pain in the lower abdomen, pain during intercourse and itching or irritation around the vulvar region. Factor analysis showed the concentration of diseases in three clusters - infection in around the vulva, other reproductive infection and abnormal discharge; and intercourse related problems. Major predictors of both symptoms of reproductive infections and treatment seeking behavior from multivariate analysis are age, education, wealth, region and awareness about RTI/STI. Knowledge and treatment seeking behavior is poor among adolescent women in India. There is need for programmatic and policy emphasis on increasing knowledge and awareness through family life education including in educational curriculum at school level.

Executive functions and sustained attention:Comparison between age groups of 19-39 and 40-59 years old

Camila Rosa de Oliveira

Full Text Available ABSTRACT Few studies involving the cognition of middle-aged adults are available in the international literature, particularly investigating the process of cognitive aging, executive components and attention. Objectives: The aim of this study was to investigate whether there are differences in performance on neuropsychological tasks of executive functions and sustained attention between two age groups. Methods: The sample consisted of 87 adults aged from 19 to 59 years old, divided into two groups according to the age variable (younger adults and middle-aged adults. All participants were Brazilian and had no sensory, psychiatric or neurological disorders; subjects also had no history of alcohol abuse, and no self-reported use of illicit drugs or antipsychotics. The neuropsychological instruments administered were the Hayling Test, Trail Making Test, Bells Test and verbal fluency tasks. Results: Groups showed no significant differences in relation to sociodemographic variables, educational level or frequency of reading and writing habits. The younger adult group performed better than the middle-aged group on tasks that involved mainly processing speed, cognitive flexibility and lexical search. Conclusions: These findings serve as a valuable reference for cognitive processing in middle-aged adults, since a large number of comparative studies focus only on the younger and later phases of adulthood. Additional studies are needed to investigate possible interaction between different factors such as age and education.

Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by endocrine, neurologic, and behavioral abnormalities. We report the first case of an unbalanced de novo reciprocal translocation of chromosomes 15 and 19, 45,XY,-15,der(19)t(15;19)(q12;p13.3), resulting in monosomy for the PWS critical chromosome region. Our patient had several typical features of PWS including infantile hypotonia, a poor suck and feeding difficulties, tantrums, skin picking, compulsions, small hands and feet, and food seeking, but not hypopigmentation, a micropenis, cryptorchidism or obesity as common findings seen in PWS at the time of examination at 6 years of age. He had seizures noted from 1 to 3 years of age and marked cognitive delay. High-resolution SNP microarray analysis identified an atypical PWS type I deletion in chromosome 15 involving the proximal breakpoint BP1. The deletion extended beyond the GABRB3 gene but was proximal to the usual distal breakpoint (BP3) within the 15q11q13 region, and GABRA5, GABRG3, and OCA2 genes were intact. No deletion of band 19p13.3 was detected; therefore, the patient was not at an increased risk of tumors from the Peutz-Jeghers syndrome associated with a deletion of the STK11 gene. © 2016 S.

BACKGROUND: Patellofemoral pain is one of the most frequent knee conditions among adolescents with a prevalence of 7 %. Evidence-based treatment consists of patient education combined with hip and quadriceps strengthening. Recent evidence suggests that a large proportion of adolescents does...... not follow their exercise prescription, performing too few repetitions or too fast below the prescribed time under tension. Live feedback, such as a metronome or exercise games, has previously shown promising results in improving the quality of exercises. The aim of this study is to investigate if live...... feedback from a sensor (BandCizer™) and an iPad will improve the ability of adolescents with PFP to perform exercises as prescribed. METHODS: This study is a randomized, controlled, participant-blinded, superiority trial with a 2-group parallel design. Forty 15 to 19 year old adolescents...

Compounds which can undergo topotactic insertion of lithium are of potential technological importance in secondary lithium batteries. In this paper we present the chemical and electrochemical insertion of lithium into the binary-phase Mo15Se19, which can exist in two crystallographic forms, denoted AA and BB, when prepared from In3Mo15Se19 and In2Mo15Se19, respectively. We show that both forms can reversibly accommodate up to eight lithium atoms, yielding two new series of compounds of formula LixMo15Se19. This behavior is consistent with the electronic structure of the host material predicted from band-structure calculations. The room-temperature phase diagram of both LixMo15Se19 systems as a function of x has been established using electrochemical test cells (based on Mo15Se19 as the cathode), and in situ x-ray measurements as the cells discharge. Both LixMo15Se19 systems contain three single-phase domains as a function of x: two hexagonal phases and an orthorhombic phase. The nature of the transitions between these single phases and the variation of the lattice parameters within a single-phase domain are reported. While the mechanism of intercalation of lithium is similar for both Mo15Se19 forms, there is a drastic difference in Li intercalation behavior for the parent indium phases In2Mo15Se19 and In3Mo15Se19. We found that In2Mo15Se19 can reversibly incorporate 6.4 lithium atoms while In3Mo15Se19 does not react. This behavior is explained on the basis of structural considerations.

Full Text Available Background: India is home to the highest number of adolescents in the world. Adolescents in India suffer from lack of knowledge and empowerment to make informed sexual and reproductive health decisions. This paper analyses the prevalence of reproductive tract infections and sexually transmitted infections (RTI/STI and treatment seeking behavior among married adolescent women in India aged 15-19 years. Methods: Data from the District Level Household Survey (DLHS, 2007-08 of India were used. The prevalence of RTIs symptoms and treatment seeking behavior among women by different socio-demographic characteristics was analyzed. Factor analysis was utilized to create an index using information about 11 symptoms of RTI/STI collected in the survey. Linear and binary logistic regressions were used to know the association between infections and treatment seeking behavior with socio-demographic factors. Results: About 15 percent of adolescent women reported having any symptoms of RTI/STI. The main symptoms reported were low backache, pain in the lower abdomen, pain during intercourse and itching or irritation around the vulvar region. Factor analysis showed the concentration of diseases in three clusters – infection in around the vulva, other reproductive infection and abnormal discharge; and intercourse related problems. Major predictors of both symptoms of reproductive infections and treatment seeking behavior from multivariate analysis are age, education, wealth, region and awareness about RTI/STI. Conclusion and Public Health Implications: Knowledge and treatment seeking behavior is poor among adolescent women in India. There is need for programmatic and policy emphasis on increasing knowledge and awareness through family life education including in educational curriculum at school level.

This study addresses the question of whether the normal range for distribution of local cerebral blood flow (lCBF) in adults can be transferred to the 4- to 15-year-old age group. Twenty-three children (age: 4-15 years; mean 11±3 years, group I) and 10 adults (age: 27-56 years; mean 45±10 years, group II) without evidence of cerebrovascular disease or other brain diseases underwent technetium-99m ethyl cysteinate dimer single-photon emission tomography. Counts in cortical and subcortical regions of interest (ROIs) were related to those in cerebellar ROIs (= 100%). Relative cortical activity in group I exceeded that in group II, particularly in left parietal (107.6%±9.8% vs 84.1%±12.4%), left frontal (97.7%±6.7% vs 79.4%±8.9%) and left temporal areas (99.7%±7.4% vs 84.9%±10.1%) and in the cingulate cortex (112.1%±9.1% vs 95.9%±10.1%, P<0.05). Cerebral activity uptake per injected dose was inversely correlated with age in 19 children of group I (r -0.77, P<0.001). In group I, there was also an inverse correlation between age and the relative local count density in the parietal (r = -0.42 to -0.57), frontal (r = -0.48), temporal (r=-0.42 to -0.58) and occipital cortex (r=-0.44). In these cortical regions relative counts differed when subgroups of children aged 4-10 and 11-15 years were analysed. It is concluded that there are systematic differences between 4- to 15-year-old children and adults with regard to normal lCBF. Diagnostic use of perfusion agents has to consider age-adjusted normal flow maps; normal ranges should be determined separately for the age groups 4-10 and 11-15 years. (orig.)

Adjuvant systemic therapy prolongs disease-free and overall survival in both pre- and postmenopausal patients. Available data shown benefit from multi-agent chemotherapy, prolonged tamoxifen treatment, and ovarian ablation, and that the combination of chemo- and endocrine therapy might be advantageous. In 1978 the International (Ludwig) Breast Cancer Study Group (IBCSG) initiated four complementary randomized controlled clinical trials to evaluate the roles of chemo-endocrine combinations or endocrine therapy alone in specific populations defined by risk (for pre- and perimenopausal patients) or by age (for postmenopausal patients). The results at 10 and 13 years' median follow-up for these trials are summarized in this report and are compared to those of the Overview meta-analysis with regard to chemo-endocrine or endocrine therapy combinations. Furthermore, types of first relapses by sites and second malignant diseases are reported. 1601 evaluable patients with node positive disease were included into the studies I-IV. In Trial I (491 premenopausal patients with 1-3 positive axillary nodes) we studied the addition of low-dose continuous prednisone (p) to a cyclophosphamide-methotrexate-fluorouracil (CMF) combination. In Trial II 327 premenopausal patients with four or more positive axillary nodes were randomized to one year CMFp or to a surgical oophorectomy followed by CMFp. In Trial III (463 postmenopausal patients 65 years old or younger), combined chemoendocrine therapy (one year of CMFp plus tamoxifen (T)) was compared to endocrine therapy (1 year of p + T) or to surgery alone. In Trial IV 320 postmenopausal patients 66 to 80 years old were treated either by surgery alone or by surgery followed by 1 year prednisone and tamoxifen. In Trial I the addition of prednisone allowed a higher dose of cytotoxics to be administered compared with CMF alone. Despite this increased dose intensity, 13-year disease-free survival (DFS) and overall survival (OS) were similar

Background and Aims Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by endocrine, neurologic and behavioral abnormalities. We report the first case of an unbalanced de-novo reciprocal translocation of chromosome 15 and 19: 45,XY,-15, der (19)t(15;19)(q12;p13.3) resulting in monosomy for the PWS chromosome critical region. We performed high resolution SNP microarray to characterize the breakpoints. Case report Our patient had several typical features for PWS including infantile hypotonia, a poor suck and feeding difficulties, tantrums, skin picking, compulsions, small hands and feet and food seeking but not hypopigmentation, a micropenis, cryptorchidism or obesity as common findings seen in PWS at the time of examination at 6 years of age. He had seizures noted from 1 to 3 years of age and marked cognitive delay. Results High resolution SNP microarray analysis identified an atypical PWS Type I deletion of chromosome 15 involving proximal breakpoint BP1. The deletion extended beyond the GABRB3 gene but was proximal to the usual distal breakpoint (BP3) within the 15q11-q13 region and GABRA5, GABRG3 and OCA2 genes were intact. Conclusion We report a case with atypical features for PWS associated with an unbalanced de-novo reciprocal translocation resulting in monosomy for the 15q11.1–15q12 with intact GABRA5, GABRG3 and OCA2 genes. No deletion of 19p13.3 band was detected therefore the patient was not at an increased risk of tumors from Peutz-Jeghers syndrome associated with a deletion of the STK11 gene. PMID:27894106

To study the presence of personality disorder in cases of deliberate self harm (DSH) in young (15-24 years) and elderly (45-74 years) and compare. Deliberate self harm cases admitted in Medical and surgical departments and cases attending psychiatry department of R.G. Kar Medical College, Kolkata were studied. For diagnosis of personality disorder ICD 10 International Personality Disorder Examination (IPDE) questionnaire was used. Percentage of elderly patients having personality disorder (64%) was higher compared to young DSH patients (58.5%). In young group, most common disorder was emotionally unstable personality disorder (28.6%) and in elderly group most common was anankastic type of personality disorder (36%). Schizoid, dissocial, histrionic, and anxious-avoidant personality disorders were found in small percentages of cases. Among DSH patients, the most common personality disorder found in young age was Emotionally unstable (Impulsive and Borderline) personality disorder, but most common personality disorder found in elderly patients was Anankastic personality disorder.

The American Oystercatcher (Haematopus palliatus) Working Group: 15 years of collaborative focal species research and management

Simons, Theodore R.

2017-01-01

The American Oystercatcher (Haematopus palliatus) Working Group formed spontaneously in 2001 as coastal waterbird biologists recognized the potential for American Oystercatchers to serve as focal species for collaborative research and management. Accomplishments over the past 15 years include the establishment of rangewide surveys, color-banding protocols, mark-resight studies, a revision of the Birds of North America species account, and new mechanisms for sharing ideas and data. Collaborations among State, Federal, and private sector scientists, natural resource managers, and dedicated volunteers have provided insights into the biology and conservation of American Oystercatchers in the United States and abroad that would not have been possible without the relationships formed through the Working Group. These accomplishments illustrate how broad collaborative approaches and the engagement of the public are key elements of effective shorebird conservation programs.

Ostrauskas, Rytas

2015-04-01

To summarize the data on the prevalence of type 1 diabetes mellitus among 15-34-year-aged Lithuania inhabitants (1991-2010). New prevalent cases consist of growing-up patients with diabetes onset in childhood, i.e., up to 14 years, new onset 15-34-year-aged type 1 diabetic patients Lithuanian inhabitants, and immigrants. The data on type 1 diabetes was collected with the help of general practitioners and regional endocrinologists in Lithuania. On 31 December 1991, there were 1202 adolescent and adult 15-34-year-aged patients with type 1 diabetes mellitus or 103.59 per 100,000 inhabitants of the same age group (95% Poisson CI 97.90-109.62), and at the end of 2010 - 1533 or 187.80 (178.63-197.44), respectively in Lithuania. During 19-year period the mean increase of type 1 diabetic patients was 1.25±1.94% per year or 1.47±2.74 per 100,000 inhabitants per mean year of the study period (for males 1.42±2.14% or 1.69±3.05/100,000 and for females 1.05±1.99%, or 1.24±2.92/100,000). Regression-based linear trends showed that the prevalence of type 1 diabetes mellitus in 15-34-year-age group had a tendency to increase among males (r=0.953; p1) and females (r=0.970; p1). The age adjusted prevalence frequencies for males and females in 1991 were correspondingly 102.81/100,000 and 104.55/100,000, and in 2010 - 193.75 and 182.01. The prevalence of type 1 diabetes mellitus among 15-34-year-age males and females had a tendency to increase during 1991-2010. Copyright © 2014 Primary Care Diabetes Europe.

Background Teens who give birth at age 15–17 years are at increased risk for adverse medical and social outcomes of teen pregnancy. Methods To examine trends in the rate and proportion of births to teens aged 15–19 years that were to teens aged 15–17 years, CDC analyzed 1991–2012 National Vital Statistics System data. National Survey of Family Growth (NSFG) data from 2006–2010 were used to examine sexual experience, contraceptive use, and receipt of prevention opportunities among female teens aged 15–17 years. Results During 1991–2012, the rate of births per 1,000 teens declined from 17.9 to 5.4 for teens aged 15 years, 36.9 to 12.9 for those aged 16 years, and 60.6 to 23.7 for those aged 17 years. In 2012, the birth rate per 1,000 teens aged 15–17 years was higher for Hispanics (25.5), non-Hispanic blacks (21.9), and American Indians/Alaska Natives (17.0) compared with non-Hispanic whites (8.4) and Asians/Pacific Islanders (4.1). The rate also varied by state, ranging from 6.2 per 1,000 teens aged 15–17 years in New Hampshire to 29.0 in the District of Columbia. In 2012, there were 86,423 births to teens aged 15–17 years, accounting for 28% of all births to teens aged 15–19 years. This percentage declined from 36% in 1991 to 28% in 2012 (pteens aged 15–17 years received formal sex education on birth control or how to say no to sex, 24% had not spoken with parents about either topic; among sexually experienced female teens, 83% reported no formal sex education before first sex. Among currently sexually active female teens (those who had sex within 3 months of the survey) aged 15–17 years, 58% used clinical birth control services in the past 12 months, and 92% used contraception at last sex; however, only 1% used the most effective reversible contraceptive methods. Conclusions Births to teens aged 15–17 years have declined but still account for approximately one quarter of births to teens aged 15–19 years. Implications for public health

Nutritional transition in children under five years and women of reproductive age: a 15-years trend analysis in Peru.

Directory of Open Access Journals (Sweden)

Christian Loret de Mola

Full Text Available BACKGROUND: Rapid urbanization, increase in food availability, and changes in diet and lifestyle patterns have been changing nutritional profiles in developing nations. We aimed to describe nutritional changes in children under 5 years and women of reproductive age in Peru, during a 15-year period of rapid economic development and social policy enhancement. MATERIALS AND METHODS: Trend analyses of anthropometric measures in children of preschool age and women between 15-49 years, using the Peruvian National Demographic and Family Health Surveys (DHS from 1996 to 2011. WHO growth curves were used to define stunting, underweight, wasting and overweight in children 19 years, body mass index (BMI was analyzed both categorically and as a continuous variable. To statistically analyze the trends, we used regression models: Linear and Poisson for continuous and binary outcomes, respectively. RESULTS: We analyzed data from 123 642 women and 64 135 children, from 1996 to 2011. Decreases over time were evidenced for underweight (p<0.001, wasting (p<0.001, and stunting (p<0.001 in children under 5 y. This effect was particularly noted in urban settings. Overweight levels in children reduced (p<0.001, however this reduction stopped, in urban settings, since 2005 (∼12%. Anemia decreased in children and women (p<0.001; with higher reduction in urban (↓43% than in rural children (↓24%. BMI in women aged 15-19 years increased (p<0.001 across time, with noticeable BMI-curve shift in women older than 30 years. Moreover, obesity doubled during this period in women more than 19 y. CONCLUSION: Nutrition transition in Peru shows different patterns for urban and rural populations. Public policies should emphasize targeting both malnutrition conditions--undernutrition/stunting, overweight/obesity and anemia--considering age and place of residence in rapid developing societies like Peru.

Described for the first time in 1986, Parvovirus B19 (B19V) infection in kidney transplant recipients remains little-known and probably underestimated. The aims of this study were to establish B19V infection frequency during the first year after kidney transplant and to determine predisposing factors and manifestations of the infection in renal transplant recipients. Sixty consecutive adult patients, transplanted less than a year before, were included in this study. B19V and other opportunistic viral infections were detected retrospectively in plasma samples collected every 15 days during the first 3 months and every month from 3 months to 1 year following the kidney transplant. Demographic characteristics, immunosuppressive treatment and biological findings were recorded on each sampling date. Six patients (10%) presented B19V viremia, while eight CMV (13.3%), seven EBV (11.7%), five HHV-6 (8.3%), five BKV (8.3%), and two adenovirus (3.3%) infections were detected. The mean value of B19V viral load was 149 UI/ml. B19V infections were either reactivation or reinfection due to genotype two in five cases, while one case of primary infection with genotype 1 was observed. Neither risk factors nor biological consequences of B19V infection have been identified. These results rank B19V third among opportunistic viral infections occurring during the first year after a kidney transplant. With regard to this high incidence, and even if the risk factors and biological consequences of the infection should be assessed in larger studies, the question of systematic screening and follow-up of B19V infection in kidney transplant recipients is relevant.

We have compared the halo of 11Be, 15C, and 19C nuclei by analyzing the one-neutron stripping reaction data on the Be target at 60-, 54-, and 57-MeV/ A beam energies, respectively, within the framework of the eikonal approximation approach. The determination of effective range through the comparison of the total cross section data and prediction has revealed that the halo of 19C is the well developed, while that of 15C is the least and that of 11Be lies in between these two. The longitudinal momentum distribution data also strengthen these observations.

QuickStats: Birth Rates Among Teens Aged 15-19 Years, by Race/Hispanic Ethnicity* - National Vital Statistics System, United States,(†) 2007 and 2015(§).

Science.gov (United States)

2016-08-19

From 2007 to 2015, the birth rate for female teens aged 15-19 years declined 46%, from 41.5 to 22.3 births per 1,000, the lowest rate ever recorded for this population in the United States. In 2015, rates declined to record lows for all racial/ethnic populations, with declines ranging from 41% for non-Hispanic white teens to 54% for Hispanic teens. Despite the declines, teen birth rates by race/Hispanic ethnicity continued to reflect wide disparities, with rates ranging from 6.9 per 1,000 for Asian or Pacific Islander teens to 34.9 for Hispanic teens in 2015.

Full Text Available The Purpose of this study was to assess the periodontal conditions and treatment needs in 7-19-year-old Brazilian school children and adolescents enrolled in the urban public schools in Araraquara, São Paulo, Brazil, in 1995, to provide baseline data for monitoring changes in their periodontal status. A sample of 1,956 school children and adolescents aged 7 to 19 years was examined by two examiners previously calibrated using the CPITN (Community Pe riodontal Index of Treatment Needs. The results showed that bleeding was the most frequently observed periodontal condition in all age groups, with a mean of 3.0 sextants affected at age 15. The presence of calculus increased with age. In the 15-19-year age group, calculus and shallow pockets (3.5-5.5 mm were observed in 39.8 per cent and 1.6 per cent of the adolescents, respectively. In order to achieve the WHO oral health goal of no more than one sextant scoring GPITN 1 (bleeding or 2 (presence of dental calculus at age 15, priority should be focused on primary prevention programs to benefit the periodontal health of the majority.O objetivo deste estudo foi verificar as condições periodontais e necessidades de tratamento em crianças e adolescentes, com idades entre 7 e 19 anos, matriculados em Escolas Públicas de Araraquara, SP, Brasil, em 1995, com o propósito de se obter um banco de dados-base inicial para o monitoramento das mudanças no estado periodontal. Uma amostra de 1956 crianças e adolescentes foi examinada por duas examinadoras, previamente calibradas, usando o CPITN. Os resultados mostraram que o sangramento gengival foi a condição periodontal mais frequentemente observada em todas as idades, com média de 3,0 sextantes afetados na idade de 15 anos. A presença de cálculo dental aumentou com a idade. No grupo etário de 15-19 anos, o cálculo dental e as bolsas periodontais rasas (3,5-5,5 mm foram observados em 39,8% e 1,6% dos adolescentes, respectivamente. Com o prop

1998-01-01

From March 1982 to December 1995, 2,607 Fisics-Incor bovine pericardial bioprostheses were implanted in 2,259 patients. Mean age was 47.2 +/- 17.5 years, and 55% were male. Rheumatic fever was present in 1,301 (45.7%) patients. One thousand and seventy-three aortic valve replacements, 1,085 mitral replacements, 27 tricuspid replacements, 195 mitral-aortic replacements, and 16 other combined valve replacements were carried out. Combined procedures were performed in 788 (32.9%) patients, the most frequent being tricuspid valve repair (9.2%) and coronary artery bypass grafting (7.7%). Hospital mortality was 8.6% (194 patients), 8.6% for the mitral group, 4.7% for the aortic group, and 12.8% for double-valve replacements. The linear rates for calcification, thromboembolism, rupture, leak and endocarditis were, respectively, 1.1%, 0.2%, 0.9%, 0.1% and 0.5% patient-year. The actuarial survival curve was 56.7 +/- 5.4% in 15 years. Survival free from endocarditis was 91.92%, survival free from thromboembolism was 95 +/- 1.7%, survival free from rupture was 43.7 +/- 9.8%, survival free from leak was 98.9 +/- 4.5%, and survival free from calcification was 48.8 +/- 7.9% in 15 years. In the late postoperative period, 1,614 (80.6%) patients were in New York Heart Association functional Class I. We conclude that the results with the Fisics-Incor bovine pericardial prostheses were satisfactory in our group of patients.

This study aims to understand the diagnostic value of serum tumor markers carcinoembryonic antigen (CEA), cancer antigen 19-9 (CA19-9), cancer antigen 125 (CA125), cancer antigen 15-3 (CA15-3), and tissue polypeptide-specific antigen (TPS) in metastatic breast cancer (MBC). A total of 164 metastatic breast cancer patients in Shanxi Cancer Hospital were recruited between February 2016 and July 2016. 200 breast cancer patients without metastasis in the same period were randomly selected as the control group. The general characteristics, immunohistochemical, and pathological results were investigated between the two groups, and tumor markers were determined. There were statistical differences in the concentration and the positive rates of CEA, CA19-9, CA125, CA15-3, and TPS between the MBC and control group (Ptumor marker at 56.7% and 97.0%, respectively. In addition, two tumor markers were used for the diagnosis of MBC and the CEA and TPS combination had the highest diagnostic sensitivity with 78.7%, while the CA15-3 and CA125 combination had the highest specificity of 91.5%. Analysis of tumor markers of 164 MBC found that there were statistical differences in the positive rates of CEA and CA15-3 between bone metastases and other metastases (χ 2 =6.00, P=0.014; χ 2 =7.32, P=0.007, respectively). The sensitivity and specificity values of the CEA and CA15-3 combination in the diagnosis of bone metastases were 77.1% and 45.8%, respectively. The positive rate of TPS in the lung metastases group was lower than in other metastases (χ 2 =8.06, P=0.005).There were significant differences in the positive rates of CA15-3 and TPS between liver metastases and other metastases (χ 2 =15.42, Ptumor markers have varying diagnostic value.

Full Text Available Introduction: Adult individuals in Indonesia showed changes in diet and lack of physical activity, therefore increasing the risk of hypercholesterolemia and obesity. One of nutritional therapy for hypercholesterolemia is rice bran oil, which contains active substances that works synergistically in controlling lipid profile. The substances are gamma-orzanol, phytosterols, and vitamin E isomers (tocotrienol and tocopherol. Methods: A clinical trial was conducted for 4 weeks in City Hall of Jakarta on 20 males, age 19–55 years old, with mild-moderate hypercholesterolemia, to assess lipid profile improvement of the supplementation of rice bran oil 45 ml/days compared to 15 ml/days without changing eating patterns. Results: After 4 weeks of intervention, there was significant difference in total cholesterol level between both groups (p = 0.049. In the group that received 45 ml/days of rice bran oil, total cholesterol level decreased 14%, and in the group of 15 ml/days total cholesterol level decreased 7.8%. The reduction of LDL and triglycerides and the increase of HDL were not significantly different between both groups (p >0,05. There was no significant changes of body weight in both groups. Conclusion: This study showed that consumption of  45 ml/days rice bran oil led to better improvements in lipid profiles compare to 15 ml/days. It has been demonstrated that gamma oryzanol and plant sterols in rice bran oil have the capability to remove cholesterol from bile salt micelles, thus decreasing cholesterol absorption in intestine.

In/sub 3.3/Mo/sub 15/Se/sub 19/ was reported a few years ago, but many attempts to date to prepare the homologue sulfide were unsuccessful. The authors report herein the first synthesis of In/sub 3.4/Mo/sub 15/S/sub 19/, isostructural to the above selenide and show that indium atoms can be removed from this phase by oxidation with HCl without disturbing the Mo chalcogenide network resulting in a new binary phase Mo/sub 15/S/sub 19/. Furthermore, this phase, with an open framework structure turns out to be an interesting system for intercalation studies. The authors have shown that Mo/sub 15/S/sub 19/ can undergo topotactic redox reactions with lithium or sodium resulting in new phases of formula Li/sub 8/Mo/sub 15/S/sub 19/ respectively. These two phases are stable at room temperature in the absence of air

By 12 months, children grasp that a phonetic change to a word can change its identity (phonological distinctiveness). However, they must also grasp that some phonetic changes do not (phonological constancy). To test development of phonological constancy, sixteen 15-month-olds and sixteen 19-month-olds completed an eye-tracking task that tracked their gaze to named versus unnamed images for familiar words spoken in their native (Australian) and an unfamiliar non-native (Jamaican) regional accent of English. Both groups looked longer at named than unnamed images for Australian pronunciations, but only 19-month-olds did so for Jamaican pronunciations, indicating that phonological constancy emerges by 19 months. Vocabulary size predicted 15-month-olds' identifications for the Jamaican pronunciations, suggesting vocabulary growth is a viable predictor for phonological constancy development. © 2013 The Authors.

National Asthma Education and Prevention Program (NAEPP) guidelines recommend that periodic spirometry be performed in youth with asthma. NAEPP uses different spirometry criteria to define uncontrolled asthma for children (6-11 years) and adolescents (12+ years). To describe differences in spirometry between U.S. children and adolescents with current asthma. We examined cross-sectional spirometry data from 453 U.S. youth with current asthma age 6-19 years from the 2007-2010 National Health and Nutrition Examination Surveys. The main outcomes were percentage predicted forced expiratory volume at 1 sec (FEV1%) ≤80 and the ratio of FEV1 to forced vital capacity (FEV1/FVC) ≤0.80. We also examined the prevalence of youth with spirometry values consistent with uncontrolled asthma, using NAEPP age-specific criteria, defined for children aged 6-11 years as FEV1% ≤80 or FEV1/FVC ≤0.80, and for adolescents aged 12-19 years as FEV1% ≤80. Children 6-11 years and adolescents 12-19 years did not differ in prevalence of FEV1% ≤80 (10.1% vs. 9.0%) or FEV1/FVC ≤0.80 (30.6% vs. 29.8%). However, based on the NAEPP age-specific criteria, 33.0% of children 6-11 years and 9.0% of adolescents 12-19 years had spirometry values consistent with uncontrolled asthma (P spirometry values consistent with uncontrolled asthma did differ. The difference appears to stem mainly from the different spirometry criteria for the two age groups. © 2015 Wiley Periodicals, Inc.

To study the caries prevalence and caries experience of 5, 12 and 15-year-old children in Greece and evaluate how the disease pattern is related to their sociodemographic parameters. A stratified cluster sample of 1209, 1224 and 1257 of five, twelve and fifteen-year-old Greek children were randomly selected according to WHO guidelines for national pathfinder surveys and examined for dental caries, according to the BASCD criteria and standards. d3mft, D3MFT and their components, as well as d3mfs, D3MFS, Care Index (CI) and SiC were recorded and related to the demographic data collected concerning age, gender, counties, urban/rural areas and parents' educational status. Dental caries varied considerably between the different districts, with a mean dmft/DMFT value for each age group being 1.77, 2.05 and 3.19 respectively, while 64%, 37% and 29% of them, were with no obvious dentinal caries. Children living in rural areas demonstrated significantly higher dmft/DMFT values and less dental restorative care (CI), whereas children with fathers of a higher educational level showed significantly lower dmft/DMFT values. The significant caries (SIC) index value for the three age groups was 5.01, 4.83 and 7.07 respectively. Posterior occlusal surfaces of the permanent teeth presented most of the caries in the 12 (68%) and 15-year-old group (78%). Despite the decrease in the prevalence of caries in Greek children disparities remain. Children in rural areas and children with less educated parents had more caries and more untreated caries. All the above call for immediate intervention with comprehensive preventive programs and better geographic targeting of the dental services at a national level including targeted prevention of pit and fissure sealants on posterior permanent molars.

Vigoureux, Solène; Bajos, Nathalie; Ringa, Virginie

2018-02-01

Most women begin sexual activity as teenagers but nearly 20% of women in France younger than 25 years rely on less effective contraceptive methods (condoms or methods such as withdrawal or periodic abstinence). We sought to analyze the association with less effective contraception among women aged 15-24 years in France and communication about sex and contraception with their parents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: The analyses focused on 713 sexually active women who did not currently want a child, were using contraception, and were interviewed in 2010 in a national cross-sectional probability survey (FEcondité CONtraception Dysfonctions sexuelles [FECOND]) when they were 15-24 years old. Associations between the use of less effective contraception, social and demographic characteristics, sexual activity, health characteristics, and communication with parents and friends about sexuality and contraception were tested with logistic regression models according to age group. Less effective contraception (condoms, and barrier or natural methods) is used more often by younger women: 27.5% of 15- to 19-year-old women and 14.7% of 20- to 24-year-old women (P communication to use less effective contraception (for those 15-19 years, odds ratio = 1.97; 95% confidence interval, 0.94-4.10, and for those 20-24 years, odds ratio = 2.36; 95% confidence interval, 1.31-4.26). Difficulty in communicating with their parents, especially their mothers, about sex, is associated with young women's choice of less effective contraception.

2003-01-01

Objective: To observe the changes of bone mineral density (BMD) in young boys and girls from 6-19 years old in Beijing area. Methods: 1139 healthy young boys and girls undergoing whole body scanning with dual energy X-ray bone densitometer were divided into different groups according to sex and age. Results: There were no significant difference in body height, weight, BMD and bone mineral contents (BMC) between boys and girls from 6 to 10 years old. The annual growth rates of body height, BMD, and BMC were the fastest in girls from 6 to 14 and boys from 6 to 16 years old, respectively. Thereafter, the annual growth rates of body height, BMD, and BMC didn't significantly increase in boys and girls. There were two fast-growth periods in BMD growth stage, being at 11 and 14 years old in girls, and at 12 and 15 years old in boys. The total body BMD was significantly correlated with the height in girls under 12 years (P < 0.001, r = 0.485-0.575) and in boys under 14 years (P < 0.01-0.001, r=0.402-0.814). Afterwards, no marked correlation was found between BMD and the height in various groups. Nevertheless, the body weight was always markedly correlated with BMD in boys and girls (P < 0.001, r=0.654-0.864). Conclusions: The body height and BMD in young boys and girls had their own characteristics, and the important growth periods were under 14 years in girls and under 16 years in boys

Full Text Available Abstract Background Although some studies in Tanzania have addressed the question of sexuality and STIs among adolescents, mostly those aged 15 - 19 years, evidence on how multiple sexual partners influence condom use among 10 - 19 year-olds is limited. This study attempts to bridge this gap by testing a hypothesis that sexual relationships with multiple partners in the age group 10 - 19 years spurs condom use during sex in four districts in Tanzania. Methods Secondary analysis was performed using data from the Adolescents Module of the cross-sectional household survey on Maternal, Newborn and Child Health (MNCH that was done in Kigoma, Kilombero, Rufiji and Ulanga districts, Tanzania in 2008. A total of 612 adolescents resulting from a random sample of 1200 households participated in this study. Pearson Chi-Square was used as a test of association between multiple sexual partners and condom use. Multivariate logistic regression model was fitted to the data to assess the effect of multiple sexual partners on condom use, having adjusted for potential confounding variables. STATA (10 statistical software was used to carry out this process at 5% two-sided significance level. Results Of the 612 adolescents interviewed, 23.4% reported being sexually active and 42.0% of these reported having had multiple (> 1 sexual partners in the last 12 months. The overall prevalence of condom use among them was 39.2%. The proportion using a condom at the last sexual intercourse was higher among those who knew that they can get a condom if they want than those who did not. No evidence of association was found between multiple sexual partners and condom use (OR = 0.77, 95% CI = 0.35 - 1.67, P = 0.504. With younger adolescents (10 - 14 years being a reference, condom use was associated with age group (15 - 19: OR = 3.69, 95% CI = 1.21 - 11.25, P = 0.022 and district of residence (Kigoma: OR = 7.45, 95% CI = 1.79 - 31.06, P = 0.006; Kilombero: OR = 8.89, 95% CI = 2

Diabetes millitus was studied in 49,176 to 113,853 a-bomb survivors per year from 1963 to 1977. Three to 4 times as many men as women had an abnormal amount of sugar in their urine. In 15 years this abnormal amount increased 2.2 times in men and 2.5 times in women. Oral glucose tolerance tests were performed on 19,990 survivors. The incidence of diabetes mellitus in women was 2 to 4 times as high as that in men. In 1977 it increased five times in men and 2.7 times in women, compared to that in 1964. (Tsunoda, M.)

The interest in unicompartmental knee arthroplasty (UKA) for medial osteoarthritis has increased rapidly but the long-term follow-up of the Oxford UKAs has yet to be analysed in non-designer centres. We have examined our ten- to 15-year clinical and radiological follow-up data for the Oxford Phase III UKAs. Between January 1999 and January 2005 a total of 138 consecutive Oxford Phase III arthroplasties were performed by a single surgeon in 129 patients for medial compartment osteoarthritis (71 right and 67 left knees, mean age 72.0 years (47 to 91), mean body mass index 28.2 (20.7 to 52.2)). Both clinical data and radiographs were prospectively recorded and obtained at intervals. Of the 129 patients, 32 patients (32 knees) died, ten patients (12 knees) were not able to take part in the final clinical and radiological assessment due to physical and mental conditions, but via telephone interview it was confirmed that none of these ten patients (12 knees) had a revision of the knee arthroplasty. One patient (two knees) was lost to follow-up. The mean follow-up was 11.7 years (10 to 15). A total of 11 knees (8%) were revised. The survival at 15 years with revision for any reason as the endpoint was 90.6% (95% confidence interval (CI) 85.2 to 96.0) and revision related to the prosthesis was 99.3% (95% CI 97.9 to 100). The mean total Knee Society Score was 47 (0 to 80) pre-operatively and 81 (30 to 100) at latest follow-up. The mean Oxford Knee Score was 19 (12 to 40) pre-operatively and 42 (28 to 55) at final follow-up. Radiolucency beneath the tibial component occurred in 22 of 81 prostheses (27.2%) without evidence of loosening. This study supports the use of UKA in medial compartment osteoarthritis with excellent long-term functional and radiological outcomes with an excellent 15-year survival rate.

Full Text Available Background: Adequate sleep has been considered important for the adolescent′s health and well being. On the other hand, self-imposed sleep curtailment is now recognized as a potentially important and novel risk factor for obesity. The present study aimed to assess the prevalence of short sleep duration and its association with obesity among Saudi adolescents. Methods: This is a school-based cross-sectional study with self-reported sleep questionnaires. It was conducted during the years 2009/2010 in three cities in Saudi Arabia; Al-Khobar, Jeddah, and Riyadh. Participants were 2868 secondary-school males (1379 and females (1389 aged 15 to 19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, waist circumference, BMI, and sleeping duration. Logistic regression analysis while adjusted for age, gender, and location was used to examine the associations between sleep duration and obesity measures. Results: The mean (SD of sleep duration was 7.2 (1.6 hours/day with no significant differences between males and females. About 31% of the participants obtain less than 7 hours of sleep per day, while approximately 50% of the sample gets less than 8 hours of daily sleep. Two-way ANCOVA results while controlling for the effect of age revealed a significant gender by school-type interaction (P<0.001. In addition, adequate sleep duration increased the odds of having normal weight (adjusted odds ratios = 1.28, 95% CI = 1.08-1.50, P = 0.003. Conclusion: The present study observed a high prevalence of short sleep duration among Saudi adolescents 15- to 19-year olds and that short sleep duration was significantly associated with increased risk of overweight and obesity. Future interventions should investigate whether adopting a healthy lifestyle by adolescents with short sleep duration would improve their sleeping habits or not.

To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014. We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion. Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years. The decline in abortion was not uniform across all population groups.

Epidemiological and clinical analysis of lymphoid tissue neoplasms in the neck region over a 15-year period. There was performed retrospective analysis of 97 patients, aged 17 to 88 years, mean age of 60.3 years. The analysis included data from subjective study, physical examination, image and histopathological studies Results: Almost all cases were lymphoid neoplasms - 95 patients (98%). B cell lymphoma was the most commonly diagnosed lymphoma - 74 cases (76%), followed by Hodgkin's lymphoma- 19 cases (20%). Only two patients had T-cell lymphoma (2%). There was observed prevalence among women, K: M ratio for the whole group was 51: 46, while male predominance was reported in Hodgkin's lymphoma patients (K: M = 7: 12). Over the 15-year period, there was an increase in the number of lymphoid tumors. The most common location on the neck were lymph nodes - 71 (73.2%). Extranodal localizations (26.8%) were most often associated with salivary glands: parotid and submandibular involvement and with the dominant lymphoma of the marginal zone MALT (14 cases). In 57% of patients the fine needle aspiration biopsy (FNAB) results were false, with positive results only in 32% of patients. Tumors from lymphoid tissue in the neck region are most commonly B-cell lymphomas or Hodgkin,s lymphomas. Non-specific clinical signs and non-specific radiological images, as well as non-diagnostic results o FNAB, make it difficult to effectively differentiate lymphomas with cancer metastasis in neck lymph nodes. Histopathology results of the excised lymph nodes remains a standard for lymphoma diagnosis.

To examine whether the combined detection of serum tumor markers (CEA, CA72-4, CA19-9, CA15-3 and CA12-5) improves the sensitivity and accuracy in the diagnosis of gastric cancer (GC). An automatic chemiluminescence immune analyzer with matched kits was used to determine the levels of serum CEA, CA72-4, CA19-9, CA15-3, and CA12-5 in 87 patients with gastric cancer (GC group), 60 patients with gastric benign diseases (GBD group) who were hospitalized during the same period, and 40 healthy subjects undergoing a physical examination. The values of these 5 tumor markers in the diagnosis of gastric cancer were analyzed. The levels of serum CEA, CA72-4, CA19-9, and CA12-5 were higher in the GC group than in the GBD group and healthy subjects, and these differences were significant ( P 0.05). The combined detection of CEA, CA72-4, CA19-9, and CA12-5 had a higher diagnostic value for gastric cancer than did single detection, and the positive detection rate of the combined detection of the four tumor markers was 60.9%. The diagnostic power when using the combined detection of CA72-4, CEA, CA19-9, and CA12-5 was the best. The combined detection of serum CA72-4, CEA, CA19-9 and CA12-5 increases the sensitivity and accuracy in the diagnosis of GC and can thus be considered an important tool for early diagnosis. © 2017 by the Association of Clinical Scientists, Inc.

Mass media plays an important role in forming body image and makes the significant impact on body size perception in children and adolescents. The aim of present study was to reveal trends in depiction of body image cues in Lithuanian magazines aimed for children and adolescents in relation to changes of real body mass index (BMI) and body size perception of 16-19 y. old girls in the year 2000 and the 2015. Three popular journals published both in the year 2000 and the 2015, were chosen for in-depth analysis of their contents (the periodicity of different topics was counted and compared). Attention given to a healthy body image has increased and the promotion of especially skinny females’ body has decreased during the last 15 years from the dominant type in the year 2000 to depiction of slightly thin or normal body build in the 2015. However, the real BMI of 16-19 y. old Lithuanian girls has significantly increased during the 2000-2015 period (from 20.09 till 21.32 kg/m²; pimage issues in mass media (magazines aimed for adolescent girls) were in parallel with the proper self-esteem of body size in adolescent girls.

A premature birth can cause parental stress, anxiety and uncertainty. This study illustrates the long-term consequences of a preterm birth for family life. Retrospective study by questionnaire. Parents of 959 children, who were born in 1983 with a gestational age of less than 32 weeks or a birth weight of less than 1500 grams, were approached when their children turned 19 years old. We investigated various aspects of their family lives by means of a written questionnaire. We received completed questionnaires back from 595 parents (62%). The divorce rate was higher in families with a disabled child (26 vs. 14%). Working mothers (n = 257) and fathers (n = 506) experienced negative consequences in their workplace (36% and 2%, respectively). The risk factor was having a handicapped child. Financial problems were present in 11% of the families during the first year and 4% still experienced financial problems after 19 years; risk factors were a handicap, male gender and a low social-economic status (SES) of the parents. Of the respondents, 26% had observed a decrease in social activities and friends during the first year and 15% felt that family and friends provided insufficient support during this year. After 19 years, 4% of the respondents still experienced a negative influence on their social lives. Risk factors were a handicap, normal birth weight (no dysmaturity), male gender and low SES. 28% of parents expressed that during the first year having a preterm child was emotional challenging or difficult to accept. After 19 years, 3% still expressed an unfavourable effect of the preterm birth. Risk factors were handicap, dysmaturity and male gender. A premature birth has a great impact on the family, especially when the child has a handicap.

Full Text Available The main objective of our research was to suggest recommendations for Czech producers of clothing for brand building and marketing communication strategies with Czech consumers in age group 13 to 19 years, therefore, our goal was to analyze consumer behavior of Czech youth when buying and using clothing and to analyze factors influencing their behavior, with the emphasis on reference groups and these results are presented in this paper. The target group (consumers 13–19 years old was selected because it’s often been neglected in recent marketing researches. The research consisted of primarily qualitative research (n = 96 in the form of in-depth interviews and pilot quantitative research (n = 200 in a form of online survey. The data collection was conducted in time period March 17–April 22, 2011. On the basis of data analysis, authors suggested general recommendations for improving marketing communication strategy of fashion producers in the Czech Republic. The results hint differences in the buying behavior of clothing between respondents in the age 13–15 and 16–19 years. The group of 13–15 years old teenagers doesn’t consider clothing brands as a very important criterion when choosing particular piece of clothing, while for the older group brands matter. The 16–19 year old ones are significantly more influenced by their friends and opinion leaders, while the for the younger group this influence comes not from their peers, but mostly parents.

Craniomaxillofacial (CMF) trauma occurs in isolation or in combination with other serious injuries, including intracranial, spinal, and upper- and lower-body injuries. It is a major cause of expensive treatment and rehabilitation requirements, temporary or lifelong morbidity, and loss of human productivity. The aim of this study was to evaluate patterns of CMF trauma in a large patient sample within a 15-year time frame. Between 1991 and 2005, CMF trauma data were collected from 14,654 patients with 35,129 injuries at the Department of Cranio-Maxillofacial and Oral Surgery in Innsbruck, assessing a plethora of parameters such as injury type and mechanism as well as age and gender distribution over time. Three main groups of CMF trauma were evaluated: facial bone fractures, dentoalveolar trauma, and soft tissue injuries. Statistical comparisons were carried out using a chi-square test. This was followed by a logistic regression analysis to determine the impact of the five main causes for CMF injury. Older people were more prone to soft tissue lesions with a rising risk of 2.1% per year older, showing no significant difference between male and female patients. Younger patients were at higher risk of suffering from dentoalveolar trauma with an increase of 4.4% per year younger. This number was even higher (by 19.6%) for female patients. The risk of sustaining facial bone fractures increased each year by 4.6%. Male patients had a 66.4% times higher risk of suffering from this type of injury. In addition, 2550 patients (17.4%) suffered from 3834 concomitant injuries of other body parts. In summary, we observed changing patterns of CMF trauma over the last 15 years, paralleled by advances in refined treatment and management options for rehabilitation and reconstruction of patients suffering from CMF trauma.

The exact duration of antibody persistence to hepatitis A and B and the need for booster dosing following primary immunisation remains undefined. A long-term study was designed to follow antibody persistence and immune memory on an annual basis for up to 15 years following vaccination during adolescence. Subjects received a combined hepatitis A and B vaccine (Twinrix™, GSK Vaccines, Belgium) at 12-15 years of age, either as 2-dose of the adult formulation or 3-dose of the paediatric formulation. Blood samples were taken every year thereafter to assess antibody persistence and immune memory to hepatitis A and B. Antibodies to hepatitis A virus (anti-HAV) and hepatitis B surface antigen (anti-HBs) were measured at Years 11-15. At Year 15 immune memory was further assessed by measuring the anamnestic response to a challenge dose of the monovalent vaccine, which was administered to subjects whose antibody concentrations fell below the pre-defined cut-offs (anti-HAV: hepatitis B vaccine challenge dose administration to 19 subjects, all except one in the 3-dose group, mounted a robust anamnestic response. The safety and reactogenicity profile of the hepatitis B challenge was consistent with previous experience. Immunity to hepatitis A and B persists 15 years after adolescent vaccination with a combined hepatitis A and B vaccine. Highly effective anamnestic response indicates that a booster dose should not be required for 15 years after primary vaccination. http://www.clinicaltrials.govNCT00875485.

Rapid urbanization, increase in food availability, and changes in diet and lifestyle patterns have been changing nutritional profiles in developing nations. We aimed to describe nutritional changes in children under 5 years and women of reproductive age in Peru, during a 15-year period of rapid economic development and social policy enhancement. Trend analyses of anthropometric measures in children of preschool age and women between 15-49 years, using the Peruvian National Demographic and Family Health Surveys (DHS) from 1996 to 2011. WHO growth curves were used to define stunting, underweight, wasting and overweight in children 19 years, body mass index (BMI) was analyzed both categorically and as a continuous variable. To statistically analyze the trends, we used regression models: Linear and Poisson for continuous and binary outcomes, respectively. We analyzed data from 123 642 women and 64 135 children, from 1996 to 2011. Decreases over time were evidenced for underweight (pAnemia decreased in children and women (pPeru shows different patterns for urban and rural populations. Public policies should emphasize targeting both malnutrition conditions--undernutrition/stunting, overweight/obesity and anemia--considering age and place of residence in rapid developing societies like Peru.

The narrow range of perceived predation: a 19 group study

Directory of Open Access Journals (Sweden)

Olivier Mesly

2013-05-01

Full Text Available This paper rests largely on the works of Mesly (1999 to 2012. It argues that the phenomenon of perceived predation as a functional behavioural phenomenon is subjected to certain limits, a finding based on studies performed on 19 different groups spread over a four-year span. It also finds a constant of k = 1.3 which reflects the invariant nature of perceived predation. These findings add to the theory of financial predation which stipulates that financial predators operate below the limits of detection pertaining to their customers (and market regulators. They are experts at minimizing the perception that clients could have that they are after their money, causing them financial harm, by surprise (perceived predation. Understanding the narrow range in which financial predators operate is setting the grounds to offer better protection to investors and to implementing better control and punitive measures.

Dental caries is the most prevalent dental disease and children are one of the most affected groups. Thus, the present study was conducted to assess the average dental caries prevalence across different WHO index age groups (5, 12 & 15 years) for the past fifteen years. Literature search was performed electronically in various search engines like google scholar, PubMed, Copernicus, etc. using Dental caries and India as MeSH terms. Articles from the past 15 years reporting on dental caries prevalence and experience in India were searched and this online searching strategy collected and listed 781 articles. After evaluating their titles and abstracts, only 30 articles fulfilled the inclusion and exclusion criteria & were finally selected for complete review and data collection. Five articles which were hand searched were also included. Pooled estimates were calculated for different index age groups and different regions (Northern and Southern) separately with a confidence interval of 95% both for prevalence and experience of dental caries. The pooled prevalence of dental caries was found to be highest in 15 year olds followed by 5 and 12 years (62.02%, 48.11% & 43.34% respectively). Weighted mean was also found to be highest for 15 years, followed by 5 and 12 years (2.56±6.508, 2.49±7.78, 1.48±3.292 respectively). Pooled prevalence and weighted mean for the Northernern India region was found to be more in all the index age groups as compared to the Southernern India region. More than 40% of the children in India have shown dental caries in both primary and permanent teeth in the past 15 years. Also, Northernern region was found to be more affected by dental caries than Southern region. Since children are seen as the future of the nation, this data could be helpful in the planning of oral health care services by the concerned authorities in the community.

Objective: To investigate the hypothesis that extracorporeal shock wave lithotripsy (ESWL) increases the risk of new onset diabetes mellitus (DM) or significant changes in fasting blood sugar (FBS). Materials and Methods: A total number of 307 patients enrolled in this study. All of them had undergone ESWL for kidney stone from 1991 to 1994. In 2009, after 15-19 years, we invited patients to check their blood sugar. Results: There were 307 patients, 19.8% females, and 80.1% males. The mean age of the patients was 44 for females and 42 years for males. 47.5% had kidney stone in the left side, 42.9% in the right side and 9.4% bilateral. The mean FBS increasing was 11.86 g/dl. It was 14.54 g/dl for the right side, 8.57 g/dl for left and 16.24 g/dl for bilateral ESWL. Discussions: The increasing of FBS is more significant in shock wave intensities higher than 15.5 KV. And there wasn't any significant relationship between age, sex, body mass index (BMI) and total number of shock waves with increasing of FBS. ESWL treatment might associate with increasing FBS without any relation to age, sex and BMI. PMID:28794595

Full Text Available Background: This article estimates non-health gross domestic product (GDP losses associated with Disability-Adjusted Life Years (DALY lost among 15-59 year olds (most productive age bracket in Kenya in 2015. Methods: This study employs the lost output or human capital approach (HCA to convert the DALYs lost from all causes into their monetary equivalents. The magnitude economic haemorrhage from each disease was obtained by multiplying the per capita non-health GDP in International Dollars by the total number of DALYs lost in a specific age group (15-29 years, 30-49 years, 50-59 years. Per capita non-health GDP equals per capita GDP minus total health expenditure in 2015. Data on DALYs and per capita total health expenditure were obtained from the World Health Organization and per capita GDP data was from IMF databases. Results: Kenya lost 9,405,184 DALYs among 15-59 years olds in 2015. That DALY loss caused a haemorrhage in GDP of Int$ 29,788,392,419. Approximately 48.6% of the GDP haemorrhage resulted from communicable diseases and nutritional conditions, 37.4% from non-communicable diseases, and 14.0% from injuries.

Gillen, ZM, Miramonti, AA, McKay, BD, Jenkins, NDM, Leutzinger, TJ, and Cramer, JT. Reliability and sensitivity of the power push-up test for upper-body strength and power in 6-15-year-old male athletes. J Strength Cond Res 32(1): 83-96, 2018-The power push-up (PPU) test is an explosive upper-body test performed on a force plate and is currently being used in high school football combines throughout the United States. The purpose of this study was to quantify the reliability of the PPU test based on age and starting position (knees vs. toes) in young athletes. Sixty-eight boys (mean ± SD; age = 10.8 ± 2.0 years) were tested twice over 5 days. Boys were separated by age as 6-9 years (n = 16), 10-11 years (n = 26), and 12-15 years (n = 26). The PPU test was performed on a force plate while rotating from the knees vs. the toes. Measurements were peak force (PF, N), peak rate of force development (pRFD, N·s), average power (AP, W), and peak power (PP, W). Intraclass correlation coefficients (ICC2,1), SEMs, coefficients of variation (CVs), and minimum detectable changes (MDCs) were calculated to quantify reliability and sensitivity. Peak force from the knees in 10-15-year-olds, PF from the toes in 12-15-year-olds, and pRFD from the knees and toes in 12-15-year-olds were comparably reliable (ICC ≥ 0.84). Neither power measurements (AP or PP) for any age group, nor any measurements (PF, pRFD, AP, or PP) for the 6-9-year-olds were comparably reliable (ICC ≤ 0.74). When considering the reliable variables, PF was greater in the 12-15-year-olds than in 10-11-year-olds (p ≤ 0.05). In addition, in 12-15-year-olds, PF and pRFD were greater from the knees than from the toes (p ≤ 0.05). For reasons largely attributable to growth and development, the PPU test may be a reliable (ICC ≥ 0.80) and sensitive (CV ≤ 19%) measure of upper-body strength (PF), whereas pRFD was also reliable (ICC ≥ 0.80), but less sensitive (CV = 30-38%) in 10-15-year-old male athletes.

Full Text Available The aim of the study was to evaluate the oral cleanliness of school children in the District of Sunsari, Nepal. A multi-stage random sampling oral epidemiological survey was conducted in private and government, urban, rural town and rural village schools in 15 illakas of Sunsari District, Eastern Nepal. A total of 600, 12-13-year-old and 600 15-year-old school children were examined by trained examiners using the simplified oral hygiene index (OHI-S. The average age-group, debris and calculus index scores were combined to obtain the simplified oral hygiene index (OHI-S. The mean OHI-S scores were compared and evaluated using the parametric t-test for two independent samples. The mean OHI-S for urban 12-13-year-old school children was 0.98 compared to 1.34 for school children of rural towns and 1.44 for school children of rural villages and these differences in mean OHI-S were statistically significant ( P < 0.005. In the 15-year-old age group, urban school children had a mean OHI-S score of 1.00 compared to 1.37 for rural towns and 1.43 for rural villages. The variance in the mean OHI-S scores were statistically significant ( P < 0.005. The overall level of cleanliness in the school children surveyed was good. Children of urban schools had the lowest scores followed by school children from rural towns and then rural villages. When the mean OHI-S scores were compared with the DMFT scores, there was an inverse relationship between oral cleanliness and dental caries. Frequency of sugar consumption and the availability and affordability of fluoridated toothpaste may be important factors in the development of dental caries than oral cleanliness.

Amplification of cox2 (approximately 620 bp) from 2 mg of up to 129 years old herbarium specimens, comparing 19 extraction methods and 15 polymerases.

During the past years an increasing number of studies have focussed on the use of herbarium specimens for molecular phylogenetic investigations and several comparative studies have been published. However, in the studies reported so far usually rather large amounts of material (typically around 100 mg) were sampled for DNA extraction. This equals an amount roughly equivalent to 8 cm(2) of a medium thick leaf. For investigating the phylogeny of plant pathogens, such large amounts of tissue are usually not available or would irretrievably damage the specimens. Through systematic comparison of 19 DNA extraction protocols applied to only 2 mg of infected leaf tissue and testing 15 different DNA polymerases, we could successfully amplify a mitochondrial DNA region (cox2; approximately 620 bp) from herbarium specimens well over a hundred years old. We conclude that DNA extraction and the choice of DNA polymerase are crucial factors for successful PCR amplification from small samples of historic herbarium specimens. Through a combination of suitable DNA extraction protocols and DNA polymerases, only a fraction of the preserved plant material commonly used is necessary for successful PCR amplification. This facilitates the potential use of a far larger number of preserved specimens for molecular phylogenetic investigation and provides access to a wealth of genetic information in preserved in specimens deposited in herbaria around the world without reducing their scientific or historical value.

Full Text Available Abstract Background Lower socioeconomic position is generally associated with higher rates of smoking and alcohol consumption and lower levels of physical activity. Health-related behaviour is usually established during late childhood and adolescence. The aim of this study is to explore changes in health-related behaviour in a cohort of adolescents aged between 15 and 19, overall and by socioeconomic position. Methods The sample consisted of 844 first-year students (42.8% males, baseline in 1998 – mean age 14.9, follow-up in 2002 – mean age 18.8 from 31 secondary schools located in Kosice, Slovakia. This study focuses on changes in adolescents' smoking, alcohol use, experience with marijuana and lack of physical exercise with regard to their socioeconomic position. Four indicators of socioeconomic position were used – adolescents' current education level and employment status, and the highest education level and highest occupational status of their parents. We first made cross tabulations of HRB with these four indicators, using McNemar's test to assess differences. Next, we used logistic regression to assess adjusted associations, using likelihood ratio tests to assess statistical significance. Results Statistically significant increases were found in all health-related behaviours. Among males, the most obvious socioeconomic gradient was found in smoking, both at age 15 and at 19. Variations in socioeconomic differences in health-related behaviour were more apparent among females. Although at age 15, almost no socioeconomic differences in health-related behaviour were found, at age 19 differences were found for almost all socioeconomic indicators. Among males, only traditional socioeconomic gradients were found (the lower the socioeconomic position, the higher the prevalence of potentially harmful health-related behaviour, while among females reverse socioeconomic gradients were also found. Conclusion We confirmed an increase in unhealthy

In 2015, an estimated 18.4 million U.S. adults had current asthma, and 3,396 adult asthma deaths were reported (1). An estimated 11%-21% of asthma deaths might be attributable to occupational exposures (2). To describe asthma mortality among persons aged 15-64 years,* CDC analyzed multiple cause-of-death data † for 1999-2016 and industry and occupation information collected from 26 states § for the years 1999, 2003, 2004, and 2007-2012. Proportionate mortality ratios (PMRs) ¶ for asthma among persons aged 15-64 years were calculated. During 1999-2016, a total of 14,296 (42.9%) asthma deaths occurred among males and 19,011 (57.1%) occurred among females. Based on an estimate that 11%-21% of asthma deaths might be related to occupational exposures, during this 18-year period, 1,573-3,002 asthma deaths in males and 2,091-3,992 deaths in females might have resulted from occupational exposures. Some of these deaths might have been averted by instituting measures to prevent potential workplace exposures. The annual age-adjusted asthma death rate** per 1 million persons aged 15-64 years declined from 13.59 in 1999 to 9.34 in 2016 (pindustries and occupations underscores the importance of optimal asthma management and identification and prevention of potential workplace exposures.

Global prevalence of obesity has been increasing dramatically in all ages. Although traditional causes for obesity development have been studied widely, it is unclear whether environmental exposure of substances such as trace heavy metals affects obesity development among children and adolescents so far. Data from the National Health and Nutrition Examination Survey (1999-2011) were retrieved, and 6602 US children were analyzed in this study. Urinary level of nine trace heavy metals, including barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten, was analyzed for their association with the prevalence of obesity among children aged 6-19 years. Multiple logistic regression was performed to assess the associations adjusted for age, race/ethnicity, gender, urinary creatinine, PIR, serum cotinine, and television, video game, and computer usage. A remarkable association was found between barium exposure (OR 1.43; 95% CI 1.09-1.88; P obesity in children aged 6-19 years. Negative association was observed between cadmium (OR 0.46; 95% CI 0.33-0.64; P obesity. All the negative associations were stronger in the 6-12 years group than in the 13-19 years group. The present study demonstrated that barium might increase the occurrence of obesity, but cadmium, cobalt, and lead caused weight loss among children. The results imply that trace heavy metals may represent critical risk factors for the development of obesity, especially in the area that the state of metal contamination is serious.

Corneal donations in South Africa: A 15-year review.

York, Nicholas J; Tinley, Christopher

2017-07-28

Corneal pathology is one of the leading causes of preventable blindness in South Africa (SA). A corneal transplant can restore or significantly improve vision in most cases. However, in SA there is a gross shortage of corneal tissue available to ophthalmologists. Little has been published describing the magnitude of the problem. To describe trends in the number of corneal donors per year in SA, the number of corneal transplants performed each year, the origin of donors, the allocation of corneas to the public or private sector, and the demographics of donors. This was a retrospective review of all corneal donations to SA eye banks over the 15-year period 1 January 2002 - 31 December 2016. There was a progressive year-on-year decline in corneal donors over the study period, from 565 per year in 2002 to 89 in 2016. As a direct result, there has been an 85.5% decrease in the number of corneal transplants performed per year using locally donated corneas, from 1 049 in 2002 to 152 in 2016. Of the donors, 48.8% originated from mortuaries, 39.0% from private hospitals and 12.2% from government hospitals; donors from mortuaries showed the most significant decline over the 15-year period, decreasing by 94.8%. Of donated corneas, 79.3% were allocated to the private sector and 21.7% to the public sector. Males comprised 69.1% of donors, while 77.2% were white, 14.0% coloured, 6.3% black and 2.5% Indian/Asian. Donor age demonstrated a bimodal peak at 25 and 55 years. The number of corneal donations in SA has declined markedly, causing the burden of corneal disease requiring transplantation to rise steadily. Population groups with a low donor rate may have cultural and other objections to corneal donation, which should be a major focus of future research and initiatives aimed at reversing the current trends.

In order to enhance the photoreduction of CO2 to CH4, a new type of photocatalyst, Sb1.5Sn8.5-xTixO19.0, with high conductivity and low bandgap was developed by partially incorporating Ti into the framework of Sb1.5Sn8.5O19.0 (antimony-doped tin oxide, ATO) using a controlled hydrothermal method. XRD and TEM analyses indicated that the Sb1.5Sn8.5-xTixO19.0 particles exhibited a tetragonal crystal structure and were approximately 20 nm in size. Furthermore, the bandgap and conductivity of these materials increased with increasing Ti content. A study of the photoreduction of CO2 with H2O revealed a remarkable increase in the generation of CH4 over the Sb1.5Sn8.5-xTixO19.0 catalysts. In particular, CH4 generation was the highest when Sb1.5Sn8.5Ti1.0O19.0 was used as the photocatalyst, and was three-fold higher than that achieved by using anatase TiO2. Photoluminescence studies showed that the enhanced photocatalytic activity of the Sb1.5Sn8.5-xTixO19.0 materials could be attributed to the interfacial transfer of photogenerated charges, which led to an effective charge separation and inhibition of the recombination of photogenerated electron-hole (e-/h+) pairs.

1983-01-01

Although the [ 18 F]-2-fluoro-2-deoxyglucose positron emission tomographic technique for measuring regional glucose metabolic rate has been successfully employed for neurobehavioral studies, the long (greater than 30 min) equilibration time required may complicate the interpretation of experimental results. Positron emission tomography neurobehavioral protocols employing the continuous inhalation of CO 15 O and 19 Ne were developed for measuring regional cerebral blood flow during multiple control and stimulation periods. Timing, lung absorbed dose, statistical accuracy, and resolution were considered. Studies with 19 Ne require shorter equilibration and stimulation times than do CO 15 O studies but entail higher absorbed doses and yield poorer imaging statistics

1991-01-01

To study relationships between perceptions that 16 to 19 year old adolescents have about socialization styles and disciplinary methods used by their parents, with their view of the world, interpersonal relations, moral development, use of psychotropic substances and maladjusted behaviours, 241 adolescents--123 males--which belong to a follow up study on growth and development from northern metropolitan Santiago, Chile, were asked to answer a questionary of psychosocial development, previously elaborated by two of the authors (GS and CA). The most used socialization styles by these fathers and mothers were the negative power one (39.2% and 38.5%) and the inductive one (23.8% and 30.0%), while permissive styles occurred at much lower frequency (1.5% and 1.1%). Coincidence among parents in socialization styles was found in 47.7% and disagreement in 19.2% of cases. The inductive style and coincidence in it's use by both parents, were frequently associated to idealistic world views, autonomous and conventional moral development, satisfactory interpersonal relationships and low frequency of psychotropic consumption, and maladjusted behaviours while negative power based styles by both parents and disagreement of styles among them were rather related to realistic or negative world view, preconventional moral development, higher frequency of relational problems, psychotropic consumption and maladjusted behaviours.

Although national poison center data show that pesticides were the 8th most commonly reported substance category (3.27%) for children aged ≤5 years in 2014, there is limited information on childhood and adolescent pesticide exposures. This study assessed pesticide-related poison center exposures in children and adolescents aged ≤19 years from 2000-2013 in Texas to characterize the potential burden of pesticides. Pesticide-related poison center exposures among children and adolescents aged ≤19 years reported to Texas poison centers were identified. The distribution of exposures was estimated by gender, age category, medical outcome, management site, exposure route, and pesticide category. From 2000 to 2013, there were 61,147 pesticide-related poison center exposures in children and adolescents aged ≤19 years. The prevalence was highest among males at 864.24 per 100,000 population. The prevalence of unintentional exposures was highest among children aged ≤5 years at 2310.69 per 100,000 population, whereas the prevalence of intentional exposures was highest among adolescents aged 13-19 years at 13.82 per 100,000 population. A majority of medical outcomes reported were classified as having no effect (30.24%) and not followed, but minimal clinical effects possible (42.74%). Of all the exposures, 81.24% were managed on site. However, 57% of intentional exposures were referred to or treated at a health-care facility. The most common routes of exposure were ingestion (80.83%) and dermal (17.21%). The most common pesticide categories included rodenticides (30.02%), pyrethrins/pyrethroids (20.69%), and other and unspecified insecticides (18.14%). The study found differences in the frequency of exposures by intent for sex and age categories, and identified the most common medical outcomes, management site, exposure route, and pesticide category. Through characterizing pesticide-related poison center exposures, future interventions can be designed to address groups

Purpose/Objective: In this study we review our long term experience with helium ion therapy in treating uveal melanoma. Materials and Methods: At UCSF-LBL, 347 patients with uveal melanoma were treated with helium ions from December 1978 - May 1992. A non randomized dose searching study was undertaken beginning with 80 GyE in 5 fractions and subsequently lowered through several levels to 48 GyE in 4 fractions. The treatment period ranged from 3 to 15 days, with a mean of 7 days. The various dose groups were similar in tumor characteristics and size. Results: An overall local control rate of 96% has been achieved, with no dose response being seen at 80, 70, 60 or 50 GyE in 5 fxs. At the lowest dose level of 48 GyE in 4 fxs, the local control rate fell to 87%. Fifteen patients (4%) had local failure in the eye requiring enucleation (12 pts), laser (1 pt) or reirradiation (2 pts). The time of appearance of local failures ranges from 4 to 64 months with most occurring within 2 years. Eight of the 15 patients with local failure are dead of distant metastases. Of the 347 patients, 308 had (20(200)) vision or better in the affected eye prior to treatment. Of these, 125 (41%) have retained at least(20(200)) vision in the treated eye. Patients with tumors greater than 5 mm in ultrasound height or close to the optic nerve or fovea have a reduced chance of retaining useful vision. The total enucleation rate is 15%, 1% for local failure and 14% because of complications of the helium RT, mostly secondary to severe glaucoma. Of the 347 patients, 230 are still alive. The median follow up is 75 months, range 3-206 months. Kaplan-Maier (K-M) survival for all 347 patients was 80% at 5 years, 77% at 10 years and 68% at 15 years post treatment. Results for patients whose tumor involves the ciliary body is much worse with a 15 year K-M survival of 42%, whereas patients not having ciliary involvement have a 15 year K-M survival of 75%. The K-M survival in patients with local failure in

Co-Ti co-substituted SrM hexagonal ferrite (SrCo 1.5 Ti 1.5 Fe 9 O 19 ) was synthesized by sol-gel combustion and solid state route. The effects of sources of TiO 2 raw materials; titanium tetra-isopropoxide (TTIP) and titanyl nitrate (TN) on the phase formation behavior and properties of the ferrite were studied. The thermal decomposition behavior of the gel was studied using TG-DSC. The phase formation behavior of the ferrite was studied by using X-ray powder diffraction and FTIR analysis. Phase formation was comparatively easier in the TN-based sol-gel process. The morphology of powder and sintered ferrite was investigated using scanning electron microscope. Magnetic properties like magnetization, coercivity, permeability, tan δ µ and dielectric properties were investigated. The ferrite synthesized by sol-gel based chemical route showed higher saturation magnetization, permeability and permittivity compared to the ferrite synthesized by solid state route. - Highlights: • SrCo 1.5 Ti 1.5 Fe 9 O 19 ferrite was successfully prepared by sol–gel combustion process. • Sol-gel synthesis of the ferrite using titanyl nitrate has been reported first time. • Phase formation was easier in the titanyl nitrate based sol-gel process. • Better magneto-dielectric properties were observed in sol-gel processed ferrite.

Full Text Available Smoking is known as a major cause of chronic obstructive pulmonary disease (COPD and hence immediate and effective interventions are required for its elimination. This study aimed to collect valid data with regard to cigarette smoking in adult population of north of Iran for policy making by a meta-analysis of the documents of national non-communicable disease risk factors surveillance system. We investigated relevant evidences by searching in published and non-electronic databases. Data were extracted based on variables such as year of the study, sex, age group and prevalence of smoking habit. Based on results of heterogeneity, we applied fixed or random effects model to estimate the overall prevalence of cigarette smoking. All analyses were performed using STATA 11 software. A total of 20747 subjects (10381 males and 10366 females in five age groups 15-24, 25-34, 35-44, 45-54 and 55-64 years were interviewed. Meta-analysis in men and women showed prevalence of 19.2% (15.8-22.6% and 0.3% (0.2-0.5% respectively. Results of the present meta-analysis showed as much as one fifth of male population of north of Iran are smoker. Subgroup analysis also revealed that the rate of smoking was higher among the middle-aged men.

Smoking is the main preventable public health problem particularly for youth worldwide. The aim of the present study was to determine the prevalence of smoking habits among students at secondary and high schools, and to compare the findings with those of a study conducted 15 years ago in the same area. In this cross-sectional study 6212 students (51.2% female; 48.8% male) were selected randomly from rural and urban areas in Samsun. All students completed a face-to-face questionnaire. The overall prevalence of smoking was 13.0% (male students, 18.1%; female students, 8.2%). The mean starting age of smoking was 14.1 ± 1.5 years. Prevalence of smoking was 15.7% in urban areas and 8.1% in rural areas. The most important factors for starting smoking were social group and families. Compared with a study conducted 15 years previously in the same area for male students, smoking prevalence was increased in rural, but decreased in urban areas. Smoking prevalence in students in Samsun was similar to that in a study conducted 15 years previously. It is important to use anti-smoking campaigns directly targeted at teenager and they should be fully informed of the harmful effects of smoking. © 2015 Japan Pediatric Society.

SUMMARY Sixty seven hypertensive children age 2-18 with at least one possible clinical sign of renovascular hypertension (RVH) were enrollment into a screening program for diagnose and treatment of RVH over a 19 year period. Patients underwent a variety of biochemical and imaging studies, but in all cases, renal arteriography was used to determine the precise diagnosis and treatment strategy. Of the 67 patients 21 (31.3%) were identified with renal artery stenosis Group 1, 14 (66.6%) unilateral, 5 (23.8%) bilateral and 2 (9.6%) branches. The mean age was 13.9 +/- 3.73 years, with 26.4 +/- 35.2 months of known hypertension, mean systolic blood pressure 191.1 +/- 30.6 mmHg, mean diastolic blood pressure 135.3 +/- 21.2 mmHg and 69% due to fibromuscular dysplasia. Three therapeutic modalities were chosen: percutaneous transluminal angioplasty (PTA), surgery (autotransplant, and nephrectomy), pharmaceutical therapy with antihypertensive drugs and combination of these. The aim of the treatment was blood pressure control, prevention of chronic renal disease and renal function and organ damage preservation. The outcome was categorized as cure, improvement or no change in hypertension. PTA treated eleven patients, 2 combined with surgery (one nephrectomy and 1 autotransplant). Blood pressure was normalized in 9/11 (81.8%) after a mean follow-up of 11.5 years (range 1-18 years). All 6 RVH cases treated by surgery procedure (one after PTA) were cured and 4 cases were managed medically (pharmacological treatment). On december 2004, 19/21 (90%) RVH adolescents blood pressure was normalized with normal serum creatinina, 10 (48%) of these completed cured, 9/21 (43%) improved (normotensión with decrease in medication requirements) and 2 (9%) other cases ware lost of follow-up. The 46 non-RVH adolescents (68.7%) were treated with long term antihypertensive medications; all of these have adequate BP control and normal renal function. We conclude that our work-up used in order to

The number of people surviving until old age has been increasing worldwide. Reduction in fertility and mortality have resulted in increasing survival of populations to later life. This study examines the mortality trends among the three main ethnic groups in Malaysia, namely; the Malays, Chinese and Indians for four important age groups (adolescents, adults, middle age and elderly) for both gender. Since the data on mortality rates in Malaysia is only available in age groups such as 1-5, 5-9, 10-14, 15-19 and so on, hence some distribution or interpolation method was essential to expand it to the individual ages. In the study, the Heligman and Pollard model will be used to expand the mortality rates from the age groups to the individual ages. It was found that decreasing trend in all age groups and ethnic groups. Female mortality is significantly lower than male mortality, and the difference may be increasing. Also the mortality rates for females are different than that for males in all ethnic groups, and the difference is generally increasing until it reaches its peak at the oldest age category. Due to the decreasing trend of mortality rates, the government needs to plan for health program to support more elderly people in the coming years.

Full Text Available Information on menstrual cycle dependent variation of tumor markers in healthy women is a subject of diagnostic efficiency and has an impact in elucidating the normal function of these markers. In this study midfollicular and midluteal concentrations of serum CEA, AFP, CA 19-9, CA 125, CA 15-3 and their relations with LH, FSH, prolactin, estradiol and progesterone were evaluated during ovulatory cycles in a group of 23 healthy female individuals. Samples were collected on the 7th and 21st day of the same menstrual cycle. Tumor marker and hormone concentrations were determined with chemiluminescence or electrochemiluminescence EIA methods. A significant phase-dependent difference was observed for CA 15-3, midluteal concentrations (mean ± SEM; 26.33 ± 1.56 U/ml higher than the midfollicular (mean ± SEM; 19.27 ± 1.49 U/ml concentrations (p < 0.001. But an obvious difference for other tumor markers investigated did not exist. Significant correlations of follicular and luteal CA 125 levels with body mass index of the subjects were observed (r:0.52, p < 0.05 and r:0.57, p < 0.005, respectively.

The participants consisted in 172 14-15 years old adolescents from a technical high school. Conventional and extended high frequency audiometry, transient evoked otoacoustic emissions and questionnaire on recreational habits were administered. Hearing threshold levels (HTLs were classified as: normal (Group 1, slightly shifted (Group 2, and significantly shifted (Group 3. The musical general exposure (MGE, from participation in recreational musical activities, was categorized in low, moderate, and high exposure. The results revealed an increase of HTL in Group 2 compared with Group 1 (P < 0.01, in Group 3 compared with Group 2 (P < 0.05 only in extended high frequency range, in Group 3 compared with Group 1 (P < 0.01. Besides, a decrease in mean global amplitude, reproducibility and in frequencies amplitude in Group 2 compared with Group 1 (P < 0.05 and in Group 3 compared with Group 1 (P < 0.05. A significant difference (P < 0.05 was found in Group 1′s HTL between low and high exposure, showing higher HTL in high exposure. The sound immission measured in nightclubs (107.8-112.2 dBA and PMPs (82.9-104.6 dBA revealed sound levels risky for hearing health according to exposure times. It demonstrates the need to implement preventive and hearing health promoting actions in adolescents.

Group-13 and group-15 doping of germanane

Full Text Available Germanane, a hydrogen-terminated graphane analogue of germanium has generated interest as a potential 2D electronic material. However, the incorporation and retention of extrinsic dopant atoms in the lattice, to tune the electronic properties, remains a significant challenge. Here, we show that the group-13 element Ga and the group-15 element As, can be successfully doped into a precursor CaGe2 phase, and remain intact in the lattice after the topotactic deintercalation, using HCl, to form GeH. After deintercalation, a maximum of 1.1% As and 2.3% Ga can be substituted into the germanium lattice. Electronic transport properties of single flakes show that incorporation of dopants leads to a reduction of resistance of more than three orders of magnitude in H2O-containing atmosphere after As doping. After doping with Ga, the reduction is more than six orders of magnitude, but with significant hysteretic behavior, indicative of water-activation of dopants on the surface. Only Ga-doped germanane remains activated under vacuum, and also exhibits minimal hysteretic behavior while the sheet resistance is reduced by more than four orders of magnitude. These Ga- and As-doped germanane materials start to oxidize after one to four days in ambient atmosphere. Overall, this work demonstrates that extrinsic doping with Ga is a viable pathway towards accessing stable electronic behavior in graphane analogues of germanium.

To determine predictors of untreated dental decay among 15-34-year-olds in Australia. Data were from Australia's National Survey of Adult Oral Health, a representative survey that utilized a three-stage, stratified clustered sampling design. Models representing demographic, socioeconomic, dental service utilization and oral health perception variables were tested using multivariable logistic regression to produce odds ratios. An estimated 25.8% (95% CI 22.4-29.5) of 15-34-year-old Australians had untreated dental decay. After controlling for other covariates, those who lived in a location other than a capital city had 2.0 times the odds of having untreated dental decay than their capital city-dwelling counterparts (95% CI 1.29-3.06). Similarly, those whose highest level of education was not a university degree had 2.1 times the odds of experiencing untreated dental decay (95% CI 1.35-3.31). Perceived need of extractions or restorations predicted untreated coronal decay, with 2.9 times the odds for those who perceived a treatment need over those with no such treatment need perception (95% CI 1.84-4.53). Participants who experienced dental fear had 2.2 times the odds of having untreated dental decay (95% CI 1.38-3.41), while those who reported experiencing toothache, orofacial pain or food avoidance in the last 12 months had 1.9 times the odds of having untreated dental decay than their counterparts with no such oral health-related quality-of-life impact (95% CI 1.20-2.92). The multivariate model achieved a 'useful' level of accuracy in predicting untreated decay (area under the ROC curve = 0.74; sensitivity = 0.63; specificity = 0.73). In the Australian young adult population, residential location, education level, perceived need for dental care, dental fear, toothache, orofacial pain or food avoidance together were predictors of untreated dental decay. The prediction model had acceptable specificity, indicating that it may be useful as part of a triage system for

During the past 15 years, 2002-2016, West Nile virus (WNV) has emerged in South Dakota resulting in 509 neuroinvasive disease (NID) cases, 745 hospitalizations and 38 deaths. Culex tarsalis is the state's primary mosquito vector. South Dakota's average annual incidence of WNV-NID and death rate are the highest of any state in the U.S. WNV cases have been reported from all counties in the state. All age groups have been infected with cases peaking in the 40-44 year age group, but deaths peaking in cases 70 years and older. Although South Dakota's WNV season lasts six months, May-October, the first week of August has been the peak week of WNV disease onsets. West Nile is now enzootic in South Dakota. Every citizen, local mosquito control programs, medical and public health infrastructures must continue to prevent and respond to annual WNV outbreaks, and prepare for the next arboviral disease to emerge.

Collagenous gastritis (CG) is a rare disorder. Two patient groups are known: 1) Children and young adults, presenting with anaemia and abdominal pain, and 2) adults presenting with watery diarrhoea. In the latter group, CG is frequently associated with collagenous colitis and/or coeliac disease. This case concerns a 15-year-old boy with a bleeding ulcer. The biopsies from corpus ventriculi showed a thickened subepithelial collagen band (> 10 micrometres), and the patient was diagnosed with CG. Ulcers are rarely linked to CG. CG should be considered when ulcers are found in children and young adults.

AIM: To find a possible relationship between inflammation and CA19-9 tumor marker by analyzing data from patients with benign jaundice (BJ) and malignant jaundice (MJ). METHODS: All patients admitted for obstructive jaundice, in the period 2005-2009, were prospectively enrolled in the study, obtaining a total of 102 patients. On admission, all patients underwent complete standard blood test examinations including C-reactive protein (CRP), bilirubin, CA19-9. Patients were considered eligible for the study when they presented obstructive jaundice confirmed by instrumental examinations and increased serum bilirubin levels (total bilirubin > 2.0 mg/dL). The standard cut-off level for CA19-9 was 32 U/mL, whereas for CRP this was 1.5 mg/L. The CA19-9 level was adjusted by dividing it by the value of serum bilirubin or by the CRP value. The patients were divided into 2 groups, MJ and BJ, and after the adjustment a comparison between the 2 groups of patients was performed. Sensitivity, specificity and positive predictive values were calculated before and after the adjustment. RESULTS: Of the 102 patients, 51 were affected by BJ and 51 by MJ. Pathologic CA19-9 levels were found in 71.7% of the patients. In the group of 51 BJ patients there were 29 (56.9%) males and 22 (43.1%) females with a median age of 66 years (range 24-96 years), whereas in the MJ group there were 24 (47%) males and 27 (53%) females, with a mean age of 70 years (range 30-92 years). Pathologic CA19-9 serum level was found in 82.3% of MJ. CRP levels were pathologic in 66.6% of the patients with BJ and in 49% with MJ. Bilirubin and CA19-9 average levels were significantly higher in MJ compared with BJ (P = 0.000 and P = 0.02), while the CRP level was significantly higher in BJ (P = 0.000). Considering a CA19-9 cut-off level of 32 U/mL, 82.3% in the MJ group and 54.9% in the BJ group were positive for CA19-9 (P = 0.002). A CA19-9 cut-off of 100 U/mL increases the difference between the two groups: 35.3% in

Globally, adolescent women are at risk for gender-based violence (GBV) including sexual violence and intimate partner violence (IPV). Those in economically distressed settings are considered uniquely vulnerable. Female adolescents aged 15-19 from Baltimore, Maryland, USA; New Delhi, India; Ibadan, Nigeria; Johannesburg, South Africa; and Shanghai, China (n = 1,112) were recruited via respondent-driven sampling to participate in a cross-sectional survey. We describe the prevalence of past-year physical and sexual IPV, and lifetime and past-year non-partner sexual violence. Logistic regression models evaluated associations of GBV with substance use, sexual and reproductive health, mental health, and self-rated health. Among ever-partnered women, past-year IPV prevalence ranged from 10.2% in Shanghai to 36.6% in Johannesburg. Lifetime non-partner sexual violence ranged from 1.2% in Shanghai to 12.6% in Johannesburg. Where sufficient cases allowed additional analyses (Baltimore and Johannesburg), both IPV and non-partner sexual violence were associated with poor health across domains of substance use, sexual and reproductive health, mental health, and self-rated health; associations varied across study sites. Significant heterogeneity was observed in the prevalence of IPV and non-partner sexual violence among adolescent women in economically distressed urban settings, with upwards of 25% of ever-partnered women experiencing past-year IPV in Baltimore, Ibadan, and Johannesburg, and more than 10% of adolescent women in Baltimore and Johannesburg reporting non-partner sexual violence. Findings affirm the negative health influence of GBV even in disadvantaged urban settings that present a range of competing health threats. A multisectoral response is needed to prevent GBV against young women, mitigate its health impact, and hold perpetrators accountable. Copyright © 2014 Society for Adolescent Health and Medicine.

A high prevalence of abnormal cerebral MRI findings has been reported in low-birth-weight children. To compare MRI findings in very-low-birth-weight (VLBW) and term small-for-gestational-age (SGA) children with controls in early adolescence. Cerebral MRI was used to examine 55 VLBW, 54 SGA and 66 controls at 15 years of age. The MR images were qualitatively assessed, and size of ventricles, white-matter and grey-matter abnormalities were reported. The VLBW teenagers had a higher prevalence of various MRI abnormalities than SGA children and controls. Dilation of the ventricular system, especially of the occipital horns, was found in 82% of the VLBW group, in 19% of the SGA group and in 21% of controls. White-matter reduction was found in 53% of the VLBW, in 6% of the SGA and in 2% of controls. Corpus callosum thinning was found in 47% of the VLBW, in 2% of the SGA and in 6% of controls. Periventricular gliosis was found in 29% of the VLBW, in 4% of the SGA and in 8% of controls. Cerebral MRI pathology in white matter is a common finding in VLBW teenagers. The findings may indicate minor perinatal PVL with resulting loss of white-matter tissue and ventricular dilation. (orig.)

To estimate incidence rate of first myocardial infarction (MI with different outcomes and factors, it is influenced by, depending on the intensity of preventive measures in a population of middle-aged men during 15-year follow-up; to evaluate economic efficiency of primary medical prevention.Material and methods. Two populations of middle-aged men with a total of 6656 males (3488 men the group of active prevention and 3168 the group of comparison were followed up over 15 years.Results. The group of active prevention revealed 22.1% reduced MI incidence rate during 5-year follow-up as compared to the second group, fatal MI incidence rate was 42.4% lower, p<0.05. Mortality rate in new cases of MI was 35.8% in the group of active prevention and 48.5% at routine treatment (p<0.05. The group of active prevention continued to have 17.9% reduced MI incidence rate during the 10-year follow-up as compared to the group of routine management (p>0.05, while patients with clinical signs of ischemic heart disease (IHD and no history of previous MI kept significant distinctions in first MI incidence rate (41% less in the first group, p<0.05. First MI incidence for the 10-year period was the least at risk factors (RF absence and twice higher even at single RF presence. Combination of RF caused 4-5 fold increase in risk for MI.

The aim of this study was to present our clinical experience and results of different treatments in 83 atherosclerotic renovascular hypertensive patients treated in the last 15 years in the Instituto de nefrologia in Havana. Regardless of the type of treatment the patients were divided in two groups. Group I: 52 (62.3%) cases with standard oral hypotensive drugs alone and control of other cardiovascular risk factors (mean age 53 years old, sex m/f 50/50%, race white/no-white 75/25%, mean known hypertension follow-up 10.2 +/- 10 years, mean SBP 208 +/- 30 mmHg, mean DBP 123 +/- 17 mmHg, mean serum creatinina 1.62 mg/dl and increase peripheral plasma renin value in 61.6% of patients) and group II: 31 (37.7%) cases treated with revascularización procedures (PTA or surgery) or nephrectomy in selected patients (mean age 50 years old, sex m/f 68/32%, race white/no-white 16/84%, mean known hypertension follow-up 8.5 +/- 8.6 years, mean SBP 214 +/- 32 mmHg, mean DBP 1.31 +/- 16 mmHg, mean serum creatinina 1.85 mg/dl and increase peripheral plasma renin value 78.3% of patients). As end point for treatment results we selected: 1) hypertension cure or control, 2) evolution of the serum creatinine value and 3) kidney and patients survival. In those cases with a follow up for more than one year, in 82.9% the blood pressure was cure (21.4%) or controlled (61.4%). The proportion of failed was superior in group I (20.9%) than in group II (11.1%). All 18 cases treated by PTA with a follow up period longer than a year, blood pressure cure in 10 (55.6%), ameliorate in 5 (27.8%) and in 3 (16.6%) was unchanged (one patient lost of follow up). Nine patients were treated by surgery (3 revascularization and 6 nephrectomy), 5 (55.5%) cases cured and 4 (44.5%) ameliorate his blood pressure. Patients in group II maintain normal renal function in more cases than in group I (48.4% vs 30.8%). Both group had similar percentage of normal-normal + pathology-normal renal function (G I: 65.4% vs G

Since renal failure causes decrease in tumor marker excretion, use of these markers in cancer care and treatment in patients with renal insufficiency or hemodialysis is controversial. The aim of this study was to investigate differences of serum levels of tumor markers CA15-3, AFP, CA19-9 and CEA in patients with impaired renal function. A total of 100 patients referred to the Tabriz Immam Reza and Amiralmomenin hospital from June 2010 to November 2011 were selected for study. Subjects were divided to 3 groups of healthy, dialysis and renal failure but non hemodialysis cases, the last category being re-grouped based on creatinine clearance. No significant relationship between different groups in serum levels of CEA (P=0.99) and CA19-9 (P=0.29) tumor markers was found. A significant correlation was observed between serum levels of AFP (PCEA (r=0.05, P=0.625). Creatinine clearance significantly correlated with AFP (Ptumor markers in patients with impaired renal function should be performed with special precautions.

Childhood/adolescent obesity and stunting are associated with heightened risk of metabolic syndrome. Understanding the prevalence and patterns of stunting, the emergence of overweight/obesity in children and adolescents and the concomitant risk for metabolic syndrome is of critical importance for public health policy. To investigate the prevalence of overweight, obesity and stunting in school children and adolescents aged 6-19 years in Beijing and to compare the differences in screening rates by national and international references. School children aged 6-19 years in Xuanwu, Haidian and Fangshan district were selected. Overweight and obesity in the children was screened for using the International Obesity Task-force (IOTF) and Chinese standards. Stunting was defined as height-for-age Z-score (HAZ) less than -2 using the 2009 Chinese standards and 2007 WHO reference. A total of 99 482 children were included in this survey. The prevalences of overweight and obesity are 17.7% and 14.4% in the Chinese standard, but they are 18.1% and 8.6% in the IOTF standard; there were significant differences between the prevalences of these two standards (p overweight/obesity in boys are all significantly higher than that of girls in every age-group (p children and adolescents (2.6%) according to the Chinese standards, with 2.8% in boys, higher than the 2.5% of girls (p children and adolescents (1.2%) with 1.1% in boys and 1.3% in girls (p overweight/obesity in children and adolescents aged 6-19 years in Beijing was close to western countries, which should be highly valued when considering public health policies and the problem of growth stunting should not be ignored.

To assess the factors related to the presence of polycystic ovary syndrome (PCOS) in adolescents. This was a cross-sectional study, with female adolescents from 15 to 18 years old, divided into: group 1 (with a medical diagnosis of PCOS) and group 2 (not diagnosed with PCOS). The height-for-age index and the body mass index were used for classifying the nutritional status, and a semi-structured questionnaire was applied. The Mann-Whitney test, Fisher's exact test, Spearman correlation coefficients, and logistic regression were used. This study evaluated 485 adolescents with an average age of 16.3 ± 0.9 years old. The prevalence of PCOS was 6.2%. No difference was found between the groups regarding anthropometric parameters and period of contraceptive use; however, there were differences regarding the age at menarche (p factor against the syndrome. An association was found between younger age at menarche and the development of the PCOS in adolescents. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

To assess the differences in occlusal features in three cohorts at 9, 12 and 15 years of age, and compare orthodontic treatment need measured by the Dental Aesthetic Index (DAI) and Index of Orthodontic Treatment Need (IOTN). Cross-sectional study. School of Dentistry, University of Valencia. A total of 1086 children: 321 aged 9, 397 aged 12 and 368 aged 15. Children were examined to measure their orthodontic treatment need according to IOTN and DAI. The main outcome measure was orthodontic treatment need according to the DAI and IOTN indices. Overbite and inter-incisal diastema were the occlusal features that presented significant differences between the three groups, diminishing with age. Treatment need according to the IOTN was 15.4% at 9 years, 20.9% at 12 years and 12.8% at 15 years. Treatment need according to DAI was 44.8% at 9 years, 21.7% at 12 years and 14.1% at 15 years. The diagnostic agreement between the two indices on the treatment need by age group was very low at 9 years (Kappa 0.18) and moderate at 12 and 15 years (Kappa 0.451 and 0.405, respectively). Orthodontic treatment need is greater in the mixed dentition and falls slightly as the child grows. The greatest variation in results between 9 and 15 years were found in relation to the DAI, which is consequently not recommended for use in the mixed dentition.

Full Text Available Introduction. Increased body growth is connected with higher sensitivity to environmental influence and may be a cause of instability of body posture. This happens when trunk and lower limbs growth is more intense. Because body posture disorders are most often diagnosed in children and school adolescents, the sample chosen were subjects between 7 and 15 years old. Material and methods. The data was gathered in 2002 in the town of Polkowice. Examination concerned 2706 boys and girls aged 7 to 15 years old. The measurement included basic somatic features and for the body posture photogrammetric method was used. Results. It was indicated that the relative trunk length in both sexes was decreasing in early school period but in the three oldest groups of age there was a significant increase. The height of kyphosis was increasing significantly in both sexes with age. Most intensive growth of this parameter was observed between 12 and 13 years old subjects. In both sexes there could be seen significant increase of kyphosis depth between 12 and 14 years old and also the decrease of lumbar lordosis between 12 and 13 years old subjects. Conclusion. Significant increase of thoracical spine relative height and lumbar lordosis depth in adolescents in both sexes can be one of the causes of weakening spine stability and affect correct body posture development.

Wasfy, Samia; Nishikawa, John; Petric, Martin

1996-01-01

The prevalence of antibody to parvovirus B19 was assessed in two populations. In a group of 494 residents from Ontario and the Maritimes, virus-specific immunoglobulin (Ig) M antibody, a marker of acute infection, was found throughout the year but was most prevalent during the late winter and early spring months. The overall prevalence of IgG antibody in this group was 30.3%. In an effort to examine age-specific prevalence in this population, a second group of sera from 210 pediatric patients at The Hospital for Sick Children, Toronto, Ontario and from Red Cross blood donors was tested for the presence of B19-specific IgG, and of these, 31.4% of the samples were positive. This prevalence varied from 3.3% in the under five-year-old age group to 66.7% in the 35- to 45-year-old age group. Eighty per cent of sera from females of this group were seropositive. This study provides insight into the prevalence of parvovirus B19 IgG antibody in the population. PMID:22514456

Full Text Available Background: In the last twenty years a marked rise in overweight and obesity among children and adolescents in developed countries was observed. Obesity in this age group is a significant risk factor for type 2 diabetes and cardiovascular diseases in adulthood. So far no comparative data on overweight and obesity in Slovene children and adolescents existed. In our study the data collected during preventive examinations of five-year-old and adolescents was analysed and guidelines for management of children with high body mass index (BMI were proposed.Methods: Using the methods of descriptional statistics the data on BMI of 4685 randomly collected five-year-old children and 2474 randomly collected adolescents aged 15–16 years were analysed. Data was collected in the years 2003–2005, evaluated according to the international reference values, and compared to other populations.Results: The prevalence of overweight among five-year-old children is 18.4% and 20.9% in boys and girls respectively. The obesity criteria are fulfilled in 9.0% boys and 7.9% girls. Among adolescents 17.1% boys and 15.4% girls are overweight and 6.2% boys and 3.8% girls are obese. These results indicate that the prevalence of obesity in Slovenia is similar as in other developed European countries.Conclusions: The study showed that obesity in childhood and adolescence in Slovenia is a problem that deserves more concern in medical institutions and on national level. Further research on reasons for this condition and new programs for stimulation of physical activity and healthy nutrition of children and adolescents are warranted.

Full Text Available Morbidity due to schistosomiasis is currently controlled by treatment of schistosome infected people with the antihelminthic drug praziquantel (PZQ. Children aged up to 5 years are currently excluded from schistosome control programmes largely due to the lack of PZQ safety data in this age group. This study investigated the safety and efficacy of PZQ treatment in such children.Zimbabwean children aged 1-5 years (n = 104 were treated with PZQ tablets and side effects were assessed by questionnaire administered to their caregivers within 24 hours of taking PZQ. Treatment efficacy was determined 6 weeks after PZQ administration through schistosome egg counts in urine. The change in infection levels in the children 1-5 years old (n = 100 was compared to that in 6-10 year old children (n = 435.Pre-treatment S. haematobium infection intensity in 1-5 year olds was 14.6 eggs/10 ml urine and prevalence was 21%. Of the 104 children, 3.8% reported side effects within 24 hours of taking PZQ treatment. These were stomach ache, loss of appetite, lethargy and inflammation of the face and body. PZQ treatment significantly reduced schistosome infection levels in 1-5 year olds with an egg reduction rate (ERR of 99% and cure rate (CR of 92%. This was comparable to the efficacy of praziquantel in 6-10 year olds where ERR was 96% and CR was 67%. INTERPRETATION/SIGNIFICANCE: PZQ treatment is as safe and efficacious in children aged 1-5 years as it is in older children aged 6-10 years in whom PZQ is the drug of choice for control of schistosome infections.

Full Text Available This study aimed to estimate the prevalence of premarital sex with the opposite sex among young people in Iran using meta analysis, differentiated with gender, age group and place of residence according to previous studies over the past 15 years (2001- 2015. Among 147 published papers and reports, fifteen studies which met the criteria were selected. The data were analyzed using software of MEDCALC and CMA. The total sample size was 14989 adolescents and young people, non college students and college students, who were residents of Tehran, Ghazvin, Tabriz, Shahroud, Isfahan, Ghoochan, Karaj, and Lorestan with an age range of 16.6-23.5 years. The prevalence of premarital sex was estimated to be 22.5% in Tehran and 14.7% in other provinces. Without considering the weighted rate based on the proportion of the population of Tehran to the whole country, the mean would be 19.1% (CI: 14.4%-24.5%, and with considering the weighted rate it would be 16%. This rate is remarkably greater among men than women (29.1% vs. 12.0%. A significant heterogeneity is observed by gender and geographical locations.  Hence, about one sixth of the young populations in Iran are exposed to health risks (diseases and social outcomes (delay at marriage because of such relations which requires planning to encounter the conesquences of such phenomenon more than before.

Purpose: To evaluate the very long-term results of the randomized Post Operative Radiation Therapy in Endometrial Carcinoma (PORTEC)-1 trial for patients with Stage I endometrial carcinoma (EC), focusing on the role of prognostic factors for treatment selection and the long-term risk of second cancers. Patients and Methods: The PORTEC trial (1990-1997) included 714 patients with Stage IC Grade 1-2 or Stage IB Grade 2-3 EC. After surgery, patients were randomly allocated to external-beam pelvic radiotherapy (EBRT) or no additional treatment (NAT). Analysis was by intention to treat. Results: 426 patients were alive at the date of analysis. The median follow-up time was 13.3 years. The 15-year actuarial locoregional recurrence (LRR) rates were 6% for EBRT vs. 15.5% for NAT (p < 0.0001). The 15-year overall survival was 52% vs. 60% (p = 0.14), and the failure-free survival was 50% vs. 54% (p = 0.94). For patients with high-intermediate risk criteria, the 15-year overall survival was 41% vs. 48% (p = 0.51), and the 15-year EC-related death was 14% vs. 13%. Most LRR in the NAT group were vaginal recurrences (11.0% of 15.5%). The 15-year rates of distant metastases were 9% vs. 7% (p = 0.25). Second primary cancers had been diagnosed over 15 years in 19% of all patients, 22% vs. 16% for EBRT vs. NAT (p = 0.10), with observed vs. expected ratios of 1.6 (EBRT) and 1.2 (NAT) compared with a matched population (p = NS). Multivariate analysis confirmed the prognostic significance of Grade 3 for LRR (hazard ratio [HR] 3.4, p = 0.0003) and for EC death (HR 7.3, p < 0.0001), of age >60 (HR 3.9, p = 0.002 for LRR and 2.7, p = 0.01 for EC death) and myometrial invasion >50% (HR 1.9, p = 0.03 and HR 1.9, p = 0.02). Conclusions: The 15-year outcomes of PORTEC-1 confirm the relevance of HIR criteria for treatment selection, and a trend for long-term risk of second cancers. EBRT should be avoided in patients with low- and intermediate-risk EC.

Full Text Available Background: Total fertility rate of Uttar Pradesh is 2.7 with annual growth rate of 16.5. Age specific marital fertility rate (ASMFR in Uttar Pradesh is highest in the age group of 20-24 years (383.9 followed by 15-19 years (271.0 age group. Use of contraceptives is also very low in this most productive age group. Among the Young married women in the age group of 15-24 years the contraceptive prevalence rate (CPR is only 27.75% which is quite low than the target CPR of 60%. State level data presents a grim picture of contraceptive use in the slum areas in comparison to non-slum areas. This slum population is the most vulnerable section of our society. Aims & Objectives: i To assess the prevalence of non-use of contraceptives among young married women living in urban slums. ii To understand the reasons for non-use of contraceptives among young married women. iii To explore the factors influencing non-use of contraceptive among young married women. Materials and Methods: A cross sectional study was carried out in the urban slums of Lucknow. Out of the eight Nagar-Nigam zones in Lucknow, one Urban-Primary Health Centre was selected randomly from each zone. From each Urban- Primary Health Centre, 2 slums were selected randomly. In selected slum, all the households were visited until at least 33 young married women (15-24 years were interviewed using a pre-tested questionnaire to obtain the desired sample size of 535. The data was analyzed using SPSS 16.0. Results: Current use of contraceptives was found to be 33.8 % and almost two-thirds (66.2% of the participants were not using any form of contraceptive method. The important reasons for non-use of contraception were embarrassment / hesitancy / shyness regarding family planning, lack of knowledge about the contraceptive method or place of availability of services, opposition to contraceptive use by husband or family members and women’s desire to get pregnant. About one third of the women had no

A 19-year-old male patient with Cushing's disease was treated for 15 months with a gastric-insoluble preparation of o.p'-DDD. 12 months after the start of the o.p'-DDD therapy, the dose was reduced from 6 to 2 g/day and external pituitary irradiation (4,480 rads) was initiated. No disturbance in the secretion of human growth hormone, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone or prolactin was revealed. The clinical and laboratory signs of Cushing's disease disappeared gradually, and the patient tolerated the drug well, even at a dose of 12 g/day. At present, two years after the discontinuation of o.p'-DDD therapy and pituitary irradiation, the patient is symptom free and receives no medication. (B.G.)

Quaternary oxide halides of group 15 with zinc and cadmium

International Nuclear Information System (INIS)

Rueck, Nadia

2014-01-01

The present thesis ''Quaternary oxide halides of group 15 with zinc and cadmium'' deals with the chemical class of oxide halides, which contain d-block element cations and pnicogens. Over the past few years compounds containing pnicogene cations are intensively investigated. The reason for this is the free electron pair of the Pn"3"+ cation, which is responsible for some interesting properties. Free electron pairs do not only impact the spatial structure of molecules but also the properties of materials. The object of this work was the synthesis and characterization of compounds containing Pn"3"+ cations with free electron pairs. Due to the structure-determining effect of these free electron pairs and in combination with halides it is possible to synthesize compounds with low-dimensional structures like chains and layers. In these compounds the structure is separated into halophilic and chalcophilic sub-structures, which are held together only by weak Van der Waals forces.

Aim: Tumor markers are potentially powerful means for obtaining information about cancers whilst causing minimal morbidity, inconvenience and cost. CA 15-3 and CEA are considered useful tumor markers in monitoring breast cancer patients. The aim of this study was to evaluate which of these two markers are in better correlate with the disease in patients surgically treated for breast cancer. Material and Methods: We retrospectively reviewed values of CA15-3 and CEA in 342 patients (median age 52.18 years, range 27-78 years) with surgically treated and pathologically proven breast cancer. CA15-3 and CEA was measured by radioimmunoassay. CA15-3 levels above 30 U/ml and CEA levels above 5 ng/ml were considered as positive values. Results: Out of 342 patients, 86 had elevated CA15-3 levels (sensitivity: 25.1%) and 68 of 342 patients had positive CEA levels (sensitivity 19.9%). Two hundred thirty seven (237) of the patients suffering from breast cancer (69.3%) did not have metastatic disease. In this group CA15-3 sensitivity was 94.5%, while CEA sensitivity was 87.3%. One hundred and five (105) patients (30.7%) had metastatic disease. In this group, CA15-3 sensitivity was 69.5% and CEA sensitivity was 36.2% (P < 0.05). With regard to the correlation of the two tumor markers with clinical course patients had significantly higher levels of CA15-3 than of CEA in metastatic breast cancer. Conclusion: This result suggests CA15-3 to be the more sensitive and more specific of the two tumor markers for metastatic breast cancer detection and monitoring

Developing motor competence and physical fitness can affect the maintenance of a sufficient level of physical activity in children and adolescents. This study assesses the relationship between motor competence and physical fitness from childhood through early adolescence. A cross-sectional sample of 194 participants from 4 to 16 years old were divided into three groups; 4-6 yr. (n=42, M age=5.2, SD 0.6), 11-12 yr. (n=58, M age=12.4, SD=0.3), and 15-16 yr. (n=94, M age=15.9, SD=0.4). To assess motor competence, each child completed the Movement Assessment Battery for Children (MABC). To measure physical fitness, three tasks (strength, speed, and endurance) were selected from the Test of Physical Fitness (TPF). To analyze the significance of the difference between the correlation coefficient in the three age groups (samples) (4-6, 11-12, and 15-16 yr.), Fischer r-to-z transformation was used. The correlation (Pearson's) between motor competence and physical fitness in the age groups was statistically higher for the youngest age groups (4-6 and 11-12 yr.) and the adolescent group (age 15-16). The differences between the two youngest age groups were not statistically significant. The results demonstrate that the correlation between motor competence and physical fitness decreases with age.

This analysis compared the numbers of patients treated at Italian pediatric oncology group (Associazione Italiana Ematologia Oncologia Pediatrica [AIEOP]) centers with the numbers of cases predicted according to the population-based registry. It considered 32,431 patients registered in the AIEOP database (1989-2012). The ratio of observed (O) to expected (E) cases was 0.79 for children (0-14 years old) and 0.15 for adolescents (15-19 years old). The proportion of adolescents increased significantly over the years, however, from 0.05 in the earliest period to 0.10, 0.18, and then 0.28 in the latest period of observation, suggesting a greater efficacy of local/national programs dedicated to adolescents. © 2016 Wiley Periodicals, Inc.

Context Late-life depression is associated with increased risk of dementia but the temporal relationship between depression and development of dementia remains unclear. Objectives To examine the association between risk of dementia and 1) baseline depressive symptoms ; 2) past history of depression, particularly early-life (depression; and 3) individual domains of the Center for Epidemiologic Studies Depression Scale (CESD). Design A large cohort with initially non-demented participants was followed biennially for up to 15 years for incident dementia. Baseline depressive symptoms were assessed using the 11-item version of CESD (CESD-11), and defined as CESD-11 score ≥ 11. Self-reported history of depression was collected at the baseline interview. Cox proportional hazards regression was used to assess the association between depression and the dementia risk. Setting Population-based cohort drawn from members of Group Health Cooperative in Seattle, Washington. Participants A cohort of 3,410 participants without dementia aged ≥ 65 years. Results Over an average of 7.1 years follow-up, 658 participants (19%) developed dementia. At baseline, 9% of participants had depressive symptoms (CESD-11 ≥ 11) and 21% reported a past history of depression. The adjusted hazard ratio (aHR) for dementia associated with baseline depressive symptoms was 1.71 (95% confidence interval 1.37, 2.13), after adjusting for age-at-entry, gender, education, and wave of enrollment. Compared to participants without depression history, those with late-life depression were at increased dementia risk (aHR =1.46 [1.16, 1.84]), but early-life depression had no association with dementia risk (aHR=1.10 [0.83, 1.47]). Depressed mood (aHR 1.48 [1.25, 1.76]) and perceived performance difficulty (aHR 1.39 [1.15, 1.67]) were independently associated with dementia. Conclusions This study confirmed previous observations of an association between late-life depression and increased risk of dementia and

The dietary exposure to the sum of the six indicator PCBs (Σ6 PCBs; PCB 28, 52, 101, 138, 153, and 180) across different Austrian population groups was assessed in this study by combining data on occurrence from food of the Austrian market (n=157) analysed during 2006-2011 with national food consumption data. The most contaminated food group was meat, poultry, game and offal with average levels of ndl-PCBs of 5.20 ng g(-1) fat. In fish and fish products and eggs, mean concentrations of 3.89 ng g(-1) fresh weight (fw) and 4.00 ng g(-1) fat, respectively, were found. In milk and dairy products average concentrations ranged from 3.07 to 4.44 ng g(-1) fat. The mean dietary intake of Σ6 PCBs was estimated to be 3.37 ng kg(-1) bw d(-1) for children (6-15 years old), 3.19 ng kg(-1) bw d(-1) for women (19-65 years) and 2.64 ng kg(-1) bw d(-1) for men (19-65 years). In all three population groups, milk and dairy products was the major contributing food group to the total dietary intake (50-55%) followed by fish and fish products (23-27%). The exposure of all Austrian population groups is well below the tolerable daily intake (TDI) of 10 ng kg(-1) bw d(-1) proposed by WHO, accounting for 34% in children, 32% in women and 26% in men.

2013-01-01

We report on a new kind of non-covalent multi-label electrochemical immunoassay that was applied to simultaneously quantify the tumor markers CA15-3 and CA19-9. The method employs a nanohybrid composed of an ionomer and conductive titanium dioxide nanoparticles that act as a matrix support for the antibodies. The two antibodies (anti-CA153 and anti-CA199) were labeled (a) with a cobaltous dipyridine complex, and (b) with methylene blue. Labeling is based on cation-exchange interaction rather than on covalent conjugation. The redox potentials of the two labels are separated by an interval of 0.3 V. The resulting sandwich-type immunosensor was read out by differential pulse voltammetry. The potential sites and currents of the two redox probes reflect the concentration of the two analytes. The two analytes were determined with a detection limit of 1.6 U mL −1 for CA19-9, and of 0.3 U mL −1 for CA15-3 (author)

The aim of our study was to evaluate the clinical and radiographic outcomes of malseating of the acetabular liner in ceramic-on-ceramic total hip arthroplasty (THA). Outcomes for 160 ceramic-on-ceramic THAs, contributed by 116 women and 39 men, were evaluated. Clinical and radiographic measurements were obtained over a 5- to 15-year follow-up for analysis. Liner malseating was identified in 20% of cases. Outcomes for 32 cases with liner malseating (group A) were compared to outcomes for 128 joints with correct liner seating (group B). The Harris hip score at the last follow-up was 90.1 for group A and 89.6 for group B. Osteolysis was identified in 5 cases in group A (15.6%), compared to 3 cases in group B (P ceramic fracture, audible squeaking, loosening of components, and revision THA. The mean annual liner wear rate was comparable between groups, 0.0045 mm/y for group A and 0.0039 mm/y for group B. The 10-year Kaplan-Meier survivorship, based on an end point of revision THA, was 100% for group A and 99.0% for group B. Over a moderate-length follow-up of 5-15 years, malseating of the acetabular liner was not associated with negative clinical outcomes or THA survivorship. Malseating did increase the incidence of osteolysis, a risk factor for adverse effects. Long-term follow-up studies are needed to fully quantify the effects of malseating of the acetabular liner.

2018-06-01

The deformation behaviors of Cu29Zr32Ti15Al5Ni19 high entropy bulk metallic glass (HE-BMG) during the nanoindentation are presented via the large-scale molecular dynamics (MD) simulations. The indentation tests are carried out using spherical rigid indenter to investigate the microstructural evolution on the mechanical properties of HE-BMGs in terms of shear strain, indentation force, and surface morphology as well as radial distribution function (RDF). Based on the Hertzian fitting the load-displacement curve, HE-BMG Cu29Zr32Ti15Al5Ni19 has the Young's modulus of 93.1 GPa and hardness of 8.8 GPa. The indentation force requiring for the continual increasing contacted area between the indenter and the substrate goes up with the increasing of indentation depth. In addition, the symmetrical distribution of atomic displacement reveals the isotropic of HE-BMG after the indentation treatment. In the deformation region, the Al element would lead to the serious fluctuation in the first peak of RDF, which is much stronger than the other elements. The severe distortion from the atomic size difference maybe reduce the activation energy to the occurrence of shear deformation in HE-BMG, leading to the transition from brittle to ductile observed by the whole sliding of the local atom group. Through the indentation load-displacement curves at various temperatures, the softening of HE-BMG at high temperatures is in qualitative agreement with the experimental findings. Moreover, this effective strategy is used to accelerate the discovery of excellent mechanical properties of HE-BMGs by means of MD simulation, as well as understand the fundamental nanoindentation response of HE-BMGs.

Purpose: Radiation Therapy Oncology Group (RTOG) trial 9704 was the largest randomized trial to use adjuvant chemoradiation therapy for patients with pancreatic cancer. This report analyzes 5-year survival by serum level of tumor marker CA 19-9 of {<=}90 vs >90 U/mL and compares results to the those of the CONKO-001 trial. Methods and Materials: CA 19-9 expression was analyzed as a dichotomized variable ({<=}90 vs >90 U/mL). Cox proportional hazard models were used to identify the impact of the CA 19-9 value on overall survival (OS). Actuarial estimates of OS were calculated using the Kaplan-Meier method. Results: Both univariate (hazard ratio [HR] = 3.2; 95% confidence interval [CI], 2.3-4.3, P<.0001) and multivariate (HR = 3.1; 95% CI, 2.2-4.2, P<.0001) analyses demonstrated a statistically significant decrease in OS for CA 19-9 serum level of {>=}90 U/mL. For patients in the gemcitabine (Gem) treatment arm with CA 19-9 <90 U/mL, median survival was 21 months. For patients with CA 19-9 {>=}90 U/mL, this number dropped to 10 months. In patients with pancreatic head tumors in the Gem treatment arm with RT quality assurance per protocol and CA 19-9 of <90 U/mL, median survival and 5-year rate were 24 months and 34%. In comparison, the median survival and 5-year OS rate for patients in the Gem arm of the CONKO trial were 22 months and 21%. Conclusions: This analysis demonstrates that patients with postresection CA 19-9 values {>=}90 U/mL had a significantly worse survival. Patients with pancreatic head tumors treated with Gem with CA 19-9 serum level of <90 U/mL and per protocol RT had favorable survival compared to that seen in the CONKO trial. CA 19-9 is a stratification factor for the current RTOG adjuvant pancreas trial (0848).

Co-Ti co-substituted SrM hexagonal ferrite (SrCo{sub 1.5}Ti{sub 1.5}Fe{sub 9}O{sub 19}) was synthesized by sol-gel combustion and solid state route. The effects of sources of TiO{sub 2} raw materials; titanium tetra-isopropoxide (TTIP) and titanyl nitrate (TN) on the phase formation behavior and properties of the ferrite were studied. The thermal decomposition behavior of the gel was studied using TG-DSC. The phase formation behavior of the ferrite was studied by using X-ray powder diffraction and FTIR analysis. Phase formation was comparatively easier in the TN-based sol-gel process. The morphology of powder and sintered ferrite was investigated using scanning electron microscope. Magnetic properties like magnetization, coercivity, permeability, tan δ{sub µ} and dielectric properties were investigated. The ferrite synthesized by sol-gel based chemical route showed higher saturation magnetization, permeability and permittivity compared to the ferrite synthesized by solid state route. - Highlights: • SrCo{sub 1.5}Ti{sub 1.5}Fe{sub 9}O{sub 19} ferrite was successfully prepared by sol–gel combustion process. • Sol-gel synthesis of the ferrite using titanyl nitrate has been reported first time. • Phase formation was easier in the titanyl nitrate based sol-gel process. • Better magneto-dielectric properties were observed in sol-gel processed ferrite.

Cognitive-behavioral therapy (CBT) has been recommended for the treatment of eating disorders, and group therapy is known to have certain advantages over individual therapy. The aim of the current study was to compare the 10-year prognosis of patients who completed integrated group CBT with those who dropped out and to examine the effect of completion of group CBT on the prognosis. The participants were 65 adult patients with eating disorders. All patients were women and Japanese. The average age (19-37) of the patients was 25.1 ± 3.8 years, and the average body mass index (BMI) was 17.7 ± 2.0. We conducted integrated group CBT with the patients and compared eating disorder symptoms, mood states, coping styles, and self-esteem before and after therapy. Furthermore, we compared clinical features and the 10-year prognosis of patients who completed the treatment and those who dropped out. After 10 sessions of group therapy, Eating Attitudes Test scores, Profile of Mood States depression scores, and Coping Inventory for Stressful Situations emotion-oriented scores decreased, while Rosenberg's Self-Esteem Scale scores increased. Regarding the results of the 10-year follow up, the completer group had more patients with a good prognosis. In contrast, the dropout group had more patients with a poor prognosis. Those who completed the integrated group CBT had a good prognosis. Group therapy gives the patients an opportunity to form peer relationships, and helps them to develop communication and socialization skills. Furthermore, in the group therapy sessions, the patients develop self-awareness by listening to other members of the group and they also develop interpersonal relationships. This effect may be temporary, but experience of group therapy may provide hope for the patient and increase the chance of the patient continuing treatment.

In adulthood, conscientiousness and neuroticism are correlates of body weight and weight gain. The present research examines whether the childhood antecedents of these traits, persistence and negative reactivity, respectively, are associated with weight gain across childhood. We likewise examine sociability as a predictor of childhood weight gain and whether these three traits are associated with weight concerns and weight-management strategies in adolescence. Participants (N=4153) were drawn from the Longitudinal Study of Australian Children, an ongoing, population-based study of child and family health and well-being. At the baseline assessment, caregivers reported on their child's temperament. At every assessment from ages 4-5 to 14-15 years, study children were weighed and measured by trained staff; there were up to six biennial assessments of body mass index and waist circumference. At ages 14-15 years, study children (n=2975) also self-reported on their weight concerns and weight-management strategies. Study children rated lower in persistence or higher in negative reactivity in early childhood gained more weight between the ages of 4 and 15 years. Sociability was associated with weight gain among girls but not among boys. Lower persistence and higher negative reactivity at ages 4-5 years were also associated with greater weight concerns, restrained eating and use of unhealthy weight-management strategies at ages 14-15 years. Childhood traits related to conscientiousness and neuroticism are associated with objective weight gain across childhood and with concerns and strategies to manage weight in adolescence. These results are consistent with a lifespan perspective that indicates that trait psychological functioning contributes to health-related markers from childhood through old age.

For some biologic studies, it was necessarily to have (+) arginine marked by nitrogen 15 in the amidine group. This report describes the synthesis of the labelled arginine. The first step is the synthesis of the methyl-isourated hydro-chlorate, the intermediate reactive, from the ClNH{sub 4} isotope. The arginine is obtained from the ornithine which we previously blocked the amino group as cupric complex. The mean yield in arginine reaches 30%, based on the ammonium chloride uses. (M.B.) [French] Pour certaines etudes biologiques, il etait indispensable de disposer de (+) arginine marquee par l'azote 15 dans le groupement amidine. Ce rapport decrit la synthese de l'ariginine marquee.

We report a case of injury to an immature tooth, observed over a period of 15 years. In 1987, a 9-year-old boy fell down in a schoolyard. The right central incisor demonstrated palato-version and radiographic observations revealed that the roots of both central incisors were incomplete. Further, a root fracture in the apical region of the central incisors was observed. During the first treatment visit, the right central incisor was repositioned and both teeth splinted. After confirming that the line of fracture was aligned, the fixation was continued for 2 months. The teeth were examined periodically for the next 15 years. Both teeth had favorable outcomes with continued root development of both the apical and coronal segments with good apposition of the fracture lines.

Osseointegration implies a firm, direct and lasting connection between vital bone and screw-shaped titanium implants of defined finish and geometry-fixtures. Thus, there is no interposed tissue between fixture and bone. Osseointegration can only be achieved and maintained by a gentle surgical installation technique, a long healing time and a proper stress distribution when in function. During a 15-year period (1965-1980), 2768 fixtures were installed in 410 edentulous jaws of 371 consecutive patients. All patients were provided with facultatively removable bridges and were examined at continuous yearly controls. The surgical and prosthetic technique was developed and evaluated over a pilot period of 5 years. The results of standardized procedures applied on a consecutive clinical material with an observation time of 5-9 years were thought to properly reflect the potential of the method. In this group, 130 jaws were provided with 895 fixtures, and of these 81% of the maxillary and 91% of the mandibular fixtures remained stable, supporting bridges. In 89% of the maxillary and 100% of the mandibular cases, the bridges were continuously stable. During healing and the first year after connection of the bridge, the mean value for marginal bone loss was 1.5 mm. Thereafter only 0.1 mm was lost annually. The clinical results achieved with bridges on osseointegrated fixtures fulfill and exceed the demands set by the 1978 Harvard Conference on successful dental implantation procedures.

There are no nationally representative hearing loss (HL) prevalence data available for Canadian youth using direct measurements. The present study objectives were to estimate national prevalence of HL using audiometric pure-tone thresholds (0.5 to 8 kHz) and or distortion product otoacoustic emissions (DPOAEs) for children and adolescents, aged 3 to 19 years. This cross-sectional population-based study presents findings from the 2012/2013 Canadian Health Measures Survey, entailing an in-person household interview and hearing measurements conducted in a mobile examination clinic. The initial study sample included 2591 participants, aged 3 to 19 years, representing 6.5 million Canadians (3.3 million males). After exclusions, subsamples consisted of 2434 participants, aged 3 to 19 years and 1879 participants, aged 6 to 19 years, with valid audiometric results. Eligible participants underwent otoscopic examination, tympanometry, DPOAE, and audiometry. HL was defined as a pure-tone average >20 dB for 6- to 18-year olds and ≥26 dB for 19-year olds, for one or more of the following: four-frequency (0.5, 1, 2, and 4 kHz) pure-tone average, high-frequency (3, 4, 6, and 8 kHz) pure-tone average, and low-frequency (0.5, 1, and 2 kHz) pure-tone average. Mild HL was defined as >20 to 40 dB (6- to 18-year olds) and ≥26 to 40 dB (19-year olds). Moderate or worse HL was defined as >40 dB (6- to 19-year olds). HL in 3- to 5-year olds (n = 555) was defined as absent DPOAEs as audiometry was not conducted. Self-reported HL was evaluated using the Health Utilities Index Mark 3 hearing questions. The primary study outcome indicates that 7.7% of Canadian youth, aged 6 to 19, had any HL, for one or more pure-tone average. Four-frequency pure-tone average and high-frequency pure-tone average HL prevalence was 4.7 and 6.0%, respectively, whereas 5.8% had a low-frequency pure-tone average HL. Significantly more children/adolescents had unilateral HL. Mild HL was significantly

In this study we aimed to determine the maximal isometric muscle strength of a healthy, normal-weight, pediatric population between 6 and 15 years of age using hand-held dynamometry to establish strength reference values. The secondary objective was determining the relationship between strength and anthropometric parameters. Four hundred normal-weight Chilean children, split into 10 age groups, separated by 1-year intervals, were evaluated. Each age group included between 35 and 55 children. The strength values increased with increasing age and weight, with a correlation of 0.83 for age and 0.82 for weight. The results were similar to those reported in previous studies regarding the relationships among strength, age, and anthropometric parameters, but the reported strength differed. These results provide normal strength parameters for healthy and normal-weight Chilean children between 6 and 15 years of age and highlight the relevance of ethnicity in defining reference values for muscle strength in a pediatric population.

This study aimed to survey for group A rotaviruses (RVA) in bats from Brazil and to perform phylogenetic inferences for VP4, VP7, NSP3, NSP4 and NSP5 genes. RVA was found in 9.18 % (28/305) of tested samples. The partial genotype constellation of a Molossus molossus RVA strain was G3-P[3]-Ix-Rx-Cx-Mx-Ax-Nx-T3-E3-H6, and that of a Glossophaga soricina RVA strain was G20-P[x]-Ix-Rx-Cx-Mx-Ax-Nx-T15-Ex-H15. These findings demonstrate an important role of bats in RVA epidemiology and provide evidence of participation of bat RVA strains in interspecies transmission and reassortment events.

The superiority of the auditory over visual modality in sensorimotor synchronization-a fundamental ability to coordinate movements with external rhythms-has long been established, whereas recent metronome synchronization work showed that synchronization of a visual bouncing ball was not less stable than synchronization of auditory tones in adults. The present study examined synchronization to isochronous sequences composed of auditory tones, visual flashes, or a bouncing ball in 6- to 7-year-old children, 12- to 15-year-old children, and 19- to 29-year-old adults. Consistent with previous reporting, the results showed that synchronization stability increased with age and synchronization was less stable for flashes than for tones and bouncing balls. As for the focus of the present study, the results revealed that synchronization of the bouncing ball was less stable than synchronization of tones for younger children, but not for teenagers and adults. The finding suggests the predisposition of the auditory advantage of sensorimotor synchronization in early childhood. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Human parvovirus B19 (B19V) is one of the smallest DNA viruses and shows great resistance to most disinfectants. Therefore, it is one of the common contaminant pathogens present in blood and plasma products. Parvovirus 4 (PARV4) is a newly identified parvovirus, which is also prevalent in parenteral transmission. In this study, we aimed to evaluate the prevalence of B19V and PARV4 DNA among patients with hemophilia in Birjand County in eastern Iran. This was a cross-sectional epidemiological study comprising nearly all people with hemophilia in this region. Whole blood samples were taken after patient registration and sent for plasma isolation. After nucleic acid extraction, B19V was detected with real-time polymerase chain reaction, PARV4 DNA was then detected using sensitive semi-nested PCR. In total, there were 86 patients with hemophilia, with mean age 28.5±1.5 years. Of these, 90.7% were men and 9.3% women; 84.9% had hemophilia A and 7.0% had hemophilia B. We found 11 patients (12.8%) were positive for B19V DNA and 8 were positive (9.3%) for PARV4 DNA. The prevalence of B19V was higher in middle-aged groups rather than younger people, whereas PARV4 infection was more common in younger patients ( P B19 virus, imposing more precautionary measures for serum and blood products is recommended.

Full Text Available Background: Some studies have pointed out the influence of morphological parameters on judo performance, however the relationship between morphological variables and performance status have not yet been confirmed. In addition, there is a lack of studies focused on morphological comparison of different age categories. Objective: The aim of this study was to assess differences in the morphological parameters of judo athletes of different age and performance level. Methods: The research sample was composed of 47 male judokas (age 19.15 ± 2.93 years; body weight 77.16 ± 11.39 kg; height 178.91 ± 6.39 cm; sport age 11.47 ± 2.74 years. It was divided by: (1 age, into cadets (15-17 years, n = 19, juniors (18-20 years, n = 15, and seniors (21+ years, n = 13 category and (2 performance status (elite, n = 10; non-elite, n = 37. In all participants, body fat, and the circumference measurement of wrist, forearm, flexed arm, and calf were observed. A personal interview was used to gain information about the athlete's performance status. Results: We found out that there are significant differences in arm circumference between cadets and seniors, cadets and juniors, juniors and seniors; and in the circumference of forearm between cadets and seniors; cadets and juniors, as well. According to the performance status, we have discovered significantly higher circumference of forearm and wrist in the elite group compared to the non-elite group. Conclusion: Forearm and wrist circumference is a reliable discriminative factor and should be taken into consideration, especially when selecting judo athletes into elite teams. However, we did not confirm that subcutaneous fat is a parameter able to distinguish between judo athletes of different performance status across various age categories.

Full Text Available Liver transplantation (LT is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclo­sporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV1,2, 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation. The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers.

Meningococcal carriage is a prerequisite for invasive infection. This cross-sectional study assessed the pharyngeal carriage prevalence in healthy subjects aged 1-24 years in Embu das Artes city, São Paulo, Brazil. Pharyngeal swabs were examined for the presence of Neisseria meningitidis. The isolates were tested for different serogroups using agglutination and polymerase chain reaction. A logistic regression model assessed any independent association between Neisseria meningitidis carriage and various risk factors. A total of 87/967 subjects (9%, 95% Confidence Interval (CI): 7.3-11.0) tested positive for N. meningitidis: 6.2% (95% CI: 3.8-9.4) in 1-4 years, 8.5% (95% CI: 5.1-13.0) in 5-9 years, 12.5% (95% CI: 7.8-18.6) in 10-14 years, 12.6% (95% CI: 7.4-19.7) in 15-19 years and 9% (95% CI: 4.9-14.9) in 20-24 years age groups. Highest carriage prevalence was observed in adolescents 10-19 years old. Serogroup C was predominant (18.4%) followed by serogroup B (12.6%). The 15-19 years age group showed a significant association between number of household members and carriers of N. meningitidis. This cross-sectional study is the first in Brazil to evaluate meningococcal carriage prevalence and associated factors in a wide age range. Copyright © 2017 Sociedade Brasileira de Infectologia.

To examine the association between breakfast skipping and physical activity among US adolescents aged 12-19 years. A cross-sectional study of nationally representative 2007-2008 National Health and Nutrition Examination Survey (NHANES) data. Breakfast skipping was assessed by two 24 h dietary recalls. Physical activity was self-reported by participants and classified based on meeting national recommendations for physical activity for the appropriate age group. Multiple logistic regression analysis was used to model the association between breakfast skipping and physical activity while controlling for confounders. A total of 936 adolescents aged 12-19 years in the USA. After adjusting for family income, there was no association between breakfast skipping and meeting physical activity guidelines for age among adolescents aged 12-19 years (OR = 0.95, 95% CI 0.56, 1.32). Findings from the study differ from previous research findings on breakfast skipping and physical activity. Therefore, further research that uses large, nationally representative US samples and national recommended guidelines for physical activity is needed.

1985-01-01

A study of the process of maternal role attainment in three age groups (15 to 19 years, 20 to 29 years, and 30 to 42 years) over the first year of motherhood found that the role attainment behaviors of feelings of love for the baby, gratification in the maternal role, observed maternal behavior, and self-reported ways of handling irritating child behaviors did not show a positive linear increase over the year. Behaviors peaked at 4 months postbirth, but declined at 8 months. Interview data suggested that the challenges of the infant's developmental behaviors at 8 and 12 months contributed to feelings of role incompetency. Although age groups functioned at different levels, their patterns of behaviors over the year did not vary, except for gratification in the role, indicating that the maternal role presented similar challenges for all women. There were no significant differences by maternal age in role strain or self-image as a mother over the year.

Full Text Available Abstract Background The use of sealants as an effective measure for the prevention of pit and fissure caries in children has been well documented by several studies; either they are used on an individual or on a public health basis. In order to plan and establish a national preventive program with sealants in a community, it is mandatory to know the epidemiological pattern of caries along with other variables influencing their use and effectiveness. Aims: To assess the utilization and distribution pattern of pit and fissure sealants on the first and second permanent molars of Greek adolescents and to evaluate whether the existing usage of sealants and some socio-demographic factors are correlated to caries prevalence on the population examined Methods A stratified cluster sample of 2481 Greek adolescents was selected according to WHO guidelines (1224 twelve and 1,257 fifteen-year-old, living in urban and rural areas in 11 districts within the country. Five calibrated examiners carried out clinical examinations, recording caries experience at the dentine threshold (BASCD criteria and presence or absence of sealants along with Socio-demographic indicators associated with oral health. Mann Whitney and Pearson's chi-square non parametric tests were utilized for assessing the data. The level of significance was p Results Sealants utilization varied considerably within the different districts, with 8,3% of the 12 and 8,0% of the 15-year-old adolescents having at least one sealed molar. Sealants reduced DMFS scores by 11% in the 12-year-olds and by 24% in the 15-year-olds, while 15-year-old adolescents from rural areas had a statistically significant (p = 0.002 less chance of having sealants (71% compared to children from urban areas. Girls had higher chance to receive sealants in both age groups (26% for the 12 and 19% for the 15-year-old as well as patients that visited the dentist for prevention compared to those visiting the dentist because they

This study focused on meso porous silica SBA-15 modified with alkoxy silane functional group; phenyltriethoxysilane (PTES) and vinyltriethoxysilane (VTES) using direct synthesis and post-grafting methods. By direct synthesis method, SBA-15 template by triblock copolymer (P123) and functionalized with alkoxy silane groups at different amount of loadings were co-condensed with tetraethyl orthosilicate (TEOS) under acidic conditions. As for post-grafting method, different loadings of alkoxy silane groups were added after co-condensation of TEOS with P123 template. Both synthesis methods used calcination process to remove surfactant template at 550 degree Celsius for 5 hours. The derivatized SBA-15 was characterized by thermogravimetric analysis to evaluate the profile at different loadings of alkoxy silane groups with different synthesis method. At temperature range of 300-800 degree Celsius, post-grafting method displayed the highest weight loss of phenyl and vinyl groups. However, there was no significant difference of weight loss for different amount of organo silane groups. In this study, TGA has shown to be significant characterization means to determine the effects of different method used in synthesizing modified SBA-15. It was shown that different loading of phenyl and vinyl groups did not affect the efficiency of surfactant removal. (author)

Infants use known verbs to learn novel nouns: evidence from 15- and 19-month-olds.

Fluent speakers' representations of verbs include semantic knowledge about the nouns that can serve as their arguments. These "selectional restrictions" of a verb can in principle be recruited to learn the meaning of a novel noun. For example, the sentence He ate the carambola licenses the inference that carambola refers to something edible. We ask whether 15- and 19-month-old infants can recruit their nascent verb lexicon to identify the referents of novel nouns that appear as the verbs' subjects. We compared infants' interpretation of a novel noun (e.g., the dax) in two conditions: one in which dax is presented as the subject of animate-selecting construction (e.g., The dax is crying), and the other in which dax is the subject of an animacy-neutral construction (e.g., The dax is right here). Results indicate that by 19months, infants use their representations of known verbs to inform the meaning of a novel noun that appears as its argument. Copyright © 2014 Elsevier B.V.

We present a Monte Carlo calculation of the astrophysical rate of the 15 O(α, γ) 19 Ne reaction based on an evaluation of published experimental data. By considering the likelihood distributions of individual resonance parameters derived from measurements, estimates of upper and lower limits on the reaction rate at the 99.73% confidence level are derived in addition to the recommended, median value. These three reaction rates are used as input for three separate calculations of Type I X-ray bursts (XRBs) using spherically symmetric, hydrodynamic simulations of an accreting neutron star. In this way the influence of the 15 O(α, γ) 19 Ne reaction rate on the peak luminosity, recurrence time, and associated nucleosynthesis in models of Type I XRBs is studied. Contrary to previous findings, no substantial effect on any of these quantities is observed in a sequence of four bursts when varying the reaction rate between its lower and upper limits. Rather, the differences in these quantities are comparable to the burst-to-burst variations with a fixed reaction rate, indicating that uncertainties in the 15 O(α, γ) 19 Ne reaction rate do not strongly affect the predictions of this Type I XRB model.

Full Text Available Background and Aim: Aggressive periodontitis is one of the periodontal diseases, which affects systemically healthy individuals usually under the age of 30 years old. The disease is characterized by rapid bone destruction which is not in accordance with the quantity of bacterial plaque. The purpose of the present study was to determine the prevalence of aggressive periodontitis among 15-18 years old female students in Tehran high schools. Materials and Methods: In this cross sectional study, , 2870 students were selected from all educational areas of Tehran during 1382-83 based on systematic clustered random sampling .Probing pocket depth on 6 areas of incisors and first molars were examined in each subject. Students with pocket depth equal to or more than 4 mm on more than one tooth were referred to Shahed Dental School for radiographic examination. For cases in which the distance between the crest of interdental septa and CEJs were equal to or more than 2 mm, full clinical and radiographic examination was performed. Results: Among the subjects of study, only 4 fulfilled the diagnostic criteria of localized aggressive periodontitis. Nobody was diagnosed with generalized aggressive periodontitis. The prevalence of aggressive periodontitis among 15-18 years old schoolgirls was 0.14%. Conclusion: The results of the present study were similar to previous studies with the same age groups and diagnostic criteria in other countries. For determination of total prevalence in Tehran, similar studies in schoolboys are recommended.

Aggressive and disruptive behaviors often precede the onset of schizophrenia. In this register-based follow-up study with a case-control design, we wanted to investigate if serious delinquency was associated with future diagnoses of schizophrenia or schizoaffective disorder (here, broadly defined schizophrenia) among a nationwide consecutive sample of 15- to 19-year-old Finnish delinquents sent for a forensic psychiatric examination in 1989-2010. The sample comprised 313 delinquents with no past or current psychotic disorder. For each delinquent, four age-, gender- and place of birth -matched controls were randomly selected from the Central Population Register. Five controls (0.4%) had been treated for schizophrenia before their respective index-dates and were thus excluded from further analysis, leaving us with a control population of 1247 individuals. The subjects were followed till death, emigration or the end of 2015, whichever occurred first. Diagnoses were obtained from the Care Register for Health Care. Forty (12.8%) of the delinquents and 11 (0.9%) of the controls were diagnosed with schizophrenia later in life (HR 16.6, 95% CI 8.53-32.39, Pdelinquency and later schizophrenia. Accurate psychiatric assessments should be made in correctional services but also later in life so that any possible psychotic symptoms can be detected in individuals with a history of serious delinquency even if there were no signs of psychosis before or at the time of the crime. Future research should explore which factors influence the delinquent's risk of developing later schizophrenia. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Full Text Available Background: Studies assessing the prevalence of oral lesions in children and adolescents, particularly in gingiva are scarce in the literature. The aim of the study was to describe the distribution of gingival proliferative lesions based on clinical and histopathological diagnoses in children and adolescents. Materials and Methods: A review of clinical charts of children and adolescents aged between 0 and 18 years old, admitted to the Oral Medicine Outpatient Unit, of Universidade Federal do Paraná, for 15 years (1994–2009 was performed. Results: Six hundred and sixty-nine out of 5,129 patients treated during this period were aged between 0 and 18 years old, and 45 of these had gingival lesions. The largest number of lesions was observed between 11 and 16 years old. The majority of the patients were referred by Curitiba's public health system. Pyogenic granuloma was the most frequent lesion (19 = 42.2%, followed by peripheral giant cell lesion (11 = 24.4%, gingival fibromatosis (10 = 22.2%, and peripheral ossifying fibroma (5 = 11.1%. Conclusion: Gingival proliferative lesions can show similar clinical characteristics. Appropriate clinical and histopathological diagnoses are necessary to guide the healthcare professional to establish the adequate treatment and to estimate the risk of recurrence.

Full Text Available Background: Alopecia is one of the most important hair follicle (HF disorders, which is divided into scarring (cicatricial and nonscarring (noncicatricial types. Objective: The aim of this study is to investigate the expression of stem cell (SC markers such as cytokeratin (CK 17 and CK19 in scarring and nonscarring alopecia. Materials and Methods: Thirty patients with scalp alopecia (15 with scarring alopecia and 15 without together with ten healthy volunteers were included in this study. Biopsies were taken from all participants and stained for CK17 and CK19 using immunohistochemistry. Results: There was a statistically significant difference between the nonscarring group and the control group with regard to CK17 expression in the outer layers of the HFs (P = 0.00 and CK19 staining of the inner layers of the HFs (P = 0.008. There was a statistically significant difference between the scarring and the control groups regarding CK17 expression in the outer (P = 0.00 and the inner layers (P = 0.00 of the HFs and CK19 expression in the inner layers of the HFs (P = 0.00. CK17 expression in the outer layers (P = 0.02 and the inner layers of the HFs (P = 0.00 together with CK19 expression in the inner layers of the HFs (P = 0.00 showed statistically significant differences between scarring and nonscarring alopecia groups. Conclusions: The presence of SC markers (CK17 and CK19 in the HFs was affected in both scarring and nonscarring alopecia, but the defect in scarring alopecia is more evident than that of nonscarring alopecia. The persistence of SC markers in some types of scarring alopecia could give a hope for the recovery of these lesions. Further studies are recommended to clarify the benefit from using HF SCs in the treatment of alopecia.

Full Text Available Background: Exercise plays an important role in improving cardiovascular function. Due to the increasing tendency of children to the soccer the purpose of this investigation was to examine the effects of a 12 week plyometric and soccer training on the cardiac structure and function of healthy 13-15 years old boys. Materials and Methods: This quasi- experimental study was conducted with a pre-test and post-test design. The participants (n=20 were selected among the non-athletic healthy boys (13-15 years from Miyaneh (East Azerbaijan, Iran. After taking informed consent the participants were voluntarily participated in two equal Training and Control groups. The participants in the Exercise group performed a 12 week plyometric and soccer training. Under basic conditions and after a 12 week follow-up using the echocardiography both groups were examined for left ventricular end-diastolic dimension (LVEDD, left ventricular end-systolic dimension (LVESD, left ventricular end diastolic posterior wall dimension¬ (LVPWd, inter-ventricular septal end diastolic dimension (IVSd, stroke volume (SV, ejection fraction (EF and cardiac output (CO. Results: After a 12 week training program the LVEDD, LVPWd and SV were significantly increased (P<0.05. The EF in the Exercise group had no increase. Moreover, LVESD and IVSd were similar in both groups. Conclusion: A twelve week plyometric and soccer training in 13-15 years old boys result in significant changes in some cardiac structural and functional indexes.

Habitat fragmentation is a major driver of biodiversity loss, but observed effects vary and may depend on the group examined. Time since fragmentation may explain some differences between taxonomical groups, as some species and thus species composition respond with a delay to changes in their environment. Impacts of drivers of global change may thus be underestimated in short-term studies. In our study we experimentally fragmented nutrient-poor dry calcareous grasslands and studied the response of species richness, individual density and species composition of various groups of invertebrates (gastropods, ants, ground beetles, rove beetles, orthoptera, spiders, woodlice) in 12 small (1.5 m * 1.5 m) and 12 large (4.5 m * 4.5 m) fragments and their corresponding control plots after 7 years. We further examined responses to fragmentation in relation to body size and habitat preferences. Responses to fragmentation varied between taxonomical groups. While spider species richness and individual density were lower in fragments, the opposite was true for an orthopteran species and woodlice. Species composition and β-diversity differed between fragments and control plots for some groups. However, the interaction treatment*plot size was rarely significant. Species with high occupancy rates in undisturbed control plots responded more negatively to the fragmentation, while species with large body size were relatively more abundant in fragments in some groups. No effect of the fragmentation was found for ants, which may have the longest lag times because of long-lived colonies. However, relationships between abundance and the species' preferences for environmental factors affected by edge effects indicate that ant diversity too may be affected in the longer-term. Our results show the importance of considering different groups in conservation management in times of widespread fragmentation of landscapes. While species richness may respond slowly, changes in abundance related to

The longitudinal relationship between cognitive abilities and subsequent death was investigated among community-dwelling older Japanese adults. Participants (n = 1060; age range 60-79 years) comprised the first-wave participants of the National Institute for Longevity Sciences-Longitudinal Study of Aging. Participants' cognitive abilities were measured at baseline using the Japanese Wechsler Adult Intelligence Scale-Revised Short Form, which includes the following tests: Information (general knowledge), Similarities (logical abstract thinking), Picture Completion (visual perception and long-term visual memory) and Digit Symbol (information processing speed). By each cognitive test score, participants were classified into three groups: the high-level group (≥ the mean + 1SD), the low-level group (≤ the mean - 1SD) and the middle-level group. Data on death and moving during the subsequent 15 years were collected and analyzed using the multiple Cox proportional hazard model adjusted for physical and psychosocial covariates. During the follow-up period, 308 participants (29.06%) had died and 93 participants (8.77%) had moved. In the Similarities test, adjusted hazard ratios (HR) of the low-level group to the high-level group were significant (HR 1.49, 95% CI 1.02-2.17, P = 0.038). Furthermore, in the Digit symbol test, the adjusted HR of the low-level group to the high-level group was significant (HR 1.62, 95% CI 1.03-2.58, P = 0.038). Significant adjusted HR were not observed for the Information or Picture Completion tests. It is suggested that a lower level of logical abstract thinking and slower information processing speed are associated with shorter survival among older Japanese adults.

The aim of this population-based study was to find out whether differences in levels of physical activity have an influence on bone mass quantity and whether quadriceps muscle strength is a reliable determinant of bone mass. Included were 175 men and 157 women, aged 15-42 years. Bone mineral density (BMD) was measured at various sites by dual X-ray absorptiometry (DXA) and single photon absorptiometry (SPA). Muscle strength was assessed using an isokinetic muscle force meter. A questionnaire was used to estimate the level of physical activity. We found a positive correlation between physical activity and BMD for boys at the distal forearm and for girls at the trochanter (age group 15-16 years). Active men (age group 21-42 years) had up to 9% higher BMD levels at the hip than those who were less active. Quadriceps muscle torque was not an independent predictor of BMD. Our data suggest that a higher level of physical activity-within the limits of a "normal life style"-may have a positive effect on BMD in the proximal femur of young adults, which in turn may lessen the subsequent risk of fracture.

Fast-food consumption has increased greatly in the USA during the past three decades. However, the effect of fast food on risk of obesity and type 2 diabetes has received little attention. We aimed to investigate the association between reported fast-food habits and changes in bodyweight and insulin resistance over a 15-year period in the USA. Participants for the CARDIA study included 3031 young (age 18-30 years in 1985-86) black and white adults who were followed up with repeated dietary assessment. We used multiple linear regression models to investigate the association of frequency of fast-food restaurant visits (fast-food frequency) at baseline and follow-up with 15-year changes in bodyweight and the homoeostasis model (HOMA) for insulin resistance. Fast-food frequency was lowest for white women (about 1.3 times per week) compared with the other ethnic-sex groups (about twice a week). After adjustment for lifestyle factors, baseline fast-food frequency was directly associated with changes in bodyweight in both black (p=0.0050) and white people (p=0.0013). Change in fast-food frequency over 15 years was directly associated with changes in bodyweight in white individuals (pfast-food restaurant use at baseline and follow-up (n=203), those with frequent (more than twice a week) visits to fast-food restaurants at baseline and follow-up (n=87) gained an extra 4.5 kg of bodyweight (p=0.0054) and had a two-fold greater increase in insulin resistance (p=0.0083). Fast-food consumption has strong positive associations with weight gain and insulin resistance, suggesting that fast food increases the risk of obesity and type 2 diabetes.

110 schoolchildren aged 13-15 years were examined. 24 of them had pseudomyopia and 6 patients myopia of various forms. A control group consisted of 38 children. Central hemodynamics was estimated by average dynamic pressure, cerebral hemodynamics--by rheoencephalography, regional hemodynamics--by dopplerography of the internal carotid and suprapubic arteries. It was found that with myopia progression, the average dynamic pressure positively comes down with reduction of reographic waves amplitude in rheogram. The blood flow rate in internal carotid and suprapubic arteries has no substantial impact on myopia course. Predisposition to arterial hypotension is a risk factor for myopia development and progression.

Full Text Available Objectives The aim of this study was to evaluate socioeconomic inequalities in the prevalence of dental caries among an urban population. Methods This study was conducted among 2000 people 15-40 years of age living in Kurdistan, Iran in 2015. Using a questionnaire, data were collected by 4 trained dental students. The dependent variable was the decayed, missing, and filled teeth (DMF index. Using principal component analysis, the socioeconomic status (SES of families was determined based on their household assets. Inequality was measured using the concentration index; in addition, the Oaxaca analytical method was used to determine the contribution of various determinants to the observed inequality. Results The concentration index for poor scores on the DMF index was -0.32 (95% confidence interval [CI], -0.40 to -0.36; thus, poor DMF indices had a greater concentration in groups with a low SES (p<0.001. Decomposition analysis showed that the mean prevalence of a poor DMF index was 43.7% (95% CI, 40.4 to 46.9% in the least privileged group and 14.4% (95% CI, 9.5 to 9.2% in the most privileged group. It was found that 85.8% of the gap observed between these groups was due to differences in sex, parents’ education, and the district of residence. A poor DMF index was less prevalent among people with higher SES than among those with lower SES (odds ratio, 0.31; 95% CI, 0.19 to 0.52. Conclusions An alarming degree of SES inequality in oral health status was found in the studied community. Hence, it is suggested that inequalities in oral health status be reduced via adopting appropriate policies such as the delivery of oral health services to poorer groups and covering such services in insurance programs.

To audit the data of caesarean sections carried out in single-handed-run small private hospitals on the basis of the modified Robson criteria (Canada), to know the changing trends of caesarean sections over a considerable duration of time (15 years) in private sector, and to focus on a particular group out of the classification of caesarean section in the efforts to reduce the caesarean section rate. It is a retrospective observational study of 7342 caesarean section cases carried out in different small private maternity hospitals over a period of 15 years. The data analysed by applying the modified Robson criteria (Canada) and the changing trends were studied in the view of reducing caesarean section rate. Statistically significant increasing trend was observed in groups of both primary and repeat caesarean section cases done before the onset of labour in the last 5 years. Auditing the data of caesarean sections on the basis of the modified Robson criteria (Canada) is a better way of classification as compared to Ten Group Classification System (TGCS). The change in trends is seen only in the last 5 years, which suggests that there is shift in attitude of the obstetricians of small private hospitals in performing caesarean sections before onset of labour than performing it after the onset of labour. Our analysis suggests the obstetricians from small private hospitals to target groups 2B, 4B and 5C.

Objective This study sought to determine whether parenting style moderated the effects of delay of gratification on BMI trajectories from age 4 to 15 years. Methods Longitudinal data were analyzed on 778 children drawn from the Study of Early Child Care and Youth Development. Parenting style (authoritative, authoritarian, permissive, neglectful) was created from measures of mothers’ sensitivity and expectations for self-control when children were age 4 years. Self-regulation was also measured at 4 years using a well-known delay of gratification protocol. BMI was calculated from measured height and weight at each time point. Mixed modeling was used to test the interaction of parenting styles and ability to delay gratification on BMI trajectories from 4 to 15 years. Results There was a significant interaction effect of parenting and ability to delay on BMI growth from 4 to 15 years for boys. Boys who had authoritarian mothers and failed to delay gratification had a significantly steeper rate of growth in BMI from childhood through adolescence than children in any other parenting x delay group. Conclusions Authoritative and permissive parenting styles were protective against more rapid BMI gains for boys who could not delay gratification. Ability to delay gratification was protective against BMI gains for boys who had parents with authoritarian or neglectful parenting styles. PMID:23977874

The Stroop test enables interference between color naming and reading to be studied. Protopapas et al. (2007) reported more errors in an interference task and longer reaction times in 12.5-year-old dyslexics; also more Stroop interference with lower reading skills. The present study uses a version of the Stroop with four color cards and aims to test interference and flexibility in older dyslexic teenagers. The four cards are: color naming, reading, interference and flexibility. In the latter, subjects have to name the color of the word inhibiting reading except when the word is inside a box. This flexibility task enables the testing of the capacity for cognitive switching between tasks. Ten dyslexics (15.1 +/- 0.7 years old) and fourteen controls (14.3 +/- 1.6 years old) participated in the study. All performed the color naming, the reading, the interference and the flexibility tasks in the same order. Subsequently, they performed a sequence of 60 saccades left-right followed by the interference task. Generally, dyslexic teenagers behaved similarly to non-dyslexics as they showed fewer errors in reading and color than in the interference and flexibility tasks. However, they made more errors and needed more time to accomplish each task than non-dyslexics. The results suggest that the inhibitory and attention processes required by the Stroop test are dysfunctioning even in older dyslexics. In contrast, the study shows no evidence for particular difficulty in the flexibility task, which would constitute an argument against problems with mental switching. Following the execution of saccades, errors in the interference test were significantly reduced for dyslexics, while the time was reduced for both groups. The effects are attributed to visual attention training via saccades.

Previous studies have shown that prolonged time spent on screen-based sedentary behavior was significantly associated with lower health status in children, independent of physical activity levels. The study aimed to explore the individual and environmental correlates of screen time (ST) among 8-19-year-old students in China. The study surveyed ST using a self-administered questionnaire in Chinese students aged 8-19 years; 1063 participants were included in the final analysis. Individual and environmental correlates of ST were assessed using a mixed-effects model (for continuous outcome variables) and multiple logistic regression model (for binary outcome variables). Prolonged ST was observed in 14.7% of boys and 8.9% of girls. Of the ST, weekend and mobile phone/tablet use represented 80% and 40%, respectively. A positive relationship was observed between media accessibility and ST in both boys and girls (p negative factor for longer ST (p mobile phone/tablet or a computer rather than viewing a TV, along with increased media accessibility, increased ST. These results indicate that greater media accessibility was positively associated and the presence of parents/others was negatively associated with prolonged ST in both Chinese boys and girls. Development of new and effective strategies against prolonged ST are required, especially for small screen device-based ST on weekends.

Quaternary oxide halides of group 15 with zinc and cadmium; Quaternaere Oxidhalogenide der Gruppe 15 mit Zink und Cadmium

The present thesis ''Quaternary oxide halides of group 15 with zinc and cadmium'' deals with the chemical class of oxide halides, which contain d-block element cations and pnicogens. Over the past few years compounds containing pnicogene cations are intensively investigated. The reason for this is the free electron pair of the Pn{sup 3+} cation, which is responsible for some interesting properties. Free electron pairs do not only impact the spatial structure of molecules but also the properties of materials. The object of this work was the synthesis and characterization of compounds containing Pn{sup 3+} cations with free electron pairs. Due to the structure-determining effect of these free electron pairs and in combination with halides it is possible to synthesize compounds with low-dimensional structures like chains and layers. In these compounds the structure is separated into halophilic and chalcophilic sub-structures, which are held together only by weak Van der Waals forces.

The article is to study the clinical significance of serum CA19-9 in diagnosing malignant tumor occurred in digestive system and to select cut off values for differentiating diagnosis of a pancreatic neoplasms and pancreatitis. Using chemiluminescence immunoassay, serum CA19-9 level of below subjects were analyzed: control group (n=21); digestive system neoplasm group (n=125, with 7 cases conformed as pancreatic cancer); non-neoplastic disease group (n=387, with 15 cases conformed as pancreatitis secondary to destructive cholangitis). Receiver operating characteristic (ROC) curve was used for analyzing results and selecting cut off values. When cut off value was 18.4 kU/L, sensibility for conforming a digestive system neoplasm was 60.8%, while its related specificity against control group and non-neoplastic disease group was 95. 2% and 68.2%, respectively. Sensibility for diagnosing pancreatic neoplasm was 85.7%, while its related specificity against control group and non-pancreatic origin tumor group was 95.0% and 63.1%, respectively. When 37 kU/L was chosen as cut off value, specificity for differentiating diagnosis of pancreatic neoplasm and pancreatitis secondary to destructive cholangitis rose from 13.3% to 46.7%. Serum CA19-9 could be used as an aid in detecting digestive system neoplastic disease; it is a reliable marker for pancreatic neoplasm. Raising cut off value may help to differentiate pancreatic neoplasm and pancreatitis secondary to destructive cholangitis

Specific problems with time and timing that affect daily routines, homework, school work, and social relations have been recognized in children with ADHD. The primary treatments for children with ADHD do not specifically focus on time-related difficulties. The aim of this randomized controlled study (RCT) was to investigate how multimodal interventions, consisting of training in time-processing ability (TPA) and compensation with time-assistive devices (TAD), affect TPA and daily time management (DTM) in children with ADHD and time difficulties, compared with only educational intervention. Thirty-eight children on stable medication for ADHD in the 9-15-year age range were randomly allocated to an intervention or a control group. The children's TPA was measured with a structured assessment (KaTid), and the children's DTM was rated by a parent questionnaire (Time-Parent scale) and by children's self-reporting (Time-Self-rating). The intervention consisted of time-skill training and compensation with TAD. Data were analysed for differences in TPA and in DTM between the control and intervention groups in the 24-week follow-up. Children in the intervention group increased their TPA significantly (p = 0.019) more compared to the control group. The largest increase was in orientation to time. In addition, the parents in the intervention group rated their children's DTM as significantly (p = 0.01) improved compared with the parents in the control group. According to the children, their DTM was not significantly changed. In conclusion, a multimodal intervention consisting of time-skill training and TAD improved TPA and DTM in children with ADHD aged 9-15 years.

This study sought to determine whether parenting style moderates the effects of delay of gratification on body mass index (BMI) trajectories from ages 4-15 years. Longitudinal data were analyzed for 778 children drawn from the Study of Early Child Care and Youth Development. Parenting style (i.e., authoritative, authoritarian, permissive, and neglectful) was created from measures of mothers' sensitivity and expectations for self-control when children were age 4 years. Self-regulation was also measured at 4 years using a well-known delay of gratification protocol. BMI was calculated from measured height and weight at each time point. Mixed modeling was used to test the interaction of parenting styles and ability to delay gratification on BMI trajectories from 4-15 years. There was a significant interaction effect of parenting and ability to delay on BMI growth from 4-15 years for boys. Boys who had authoritarian mothers and failed to delay gratification had a significantly steeper rate of growth in BMI from childhood through adolescence than children in any other parenting by delay group. Authoritative and permissive parenting styles were protective against more rapid BMI gains for boys who could not delay gratification. Ability to delay gratification was protective against BMI gains for boys who had parents with authoritarian or neglectful parenting styles.

Chimeric antigen receptors (CARs) have been used to redirect the specificity of autologous T cells against leukemia and lymphoma with promising clinical results. Extending this approach to allogeneic T cells is problematic as they carry a significant risk of graft-versus-host disease (GVHD). Natural killer (NK) cells are highly cytotoxic effectors, killing their targets in a non-antigen-specific manner without causing GVHD. Cord blood (CB) offers an attractive, allogeneic, off-the-self source of NK cells for immunotherapy. We transduced CB-derived NK cells with a retroviral vector incorporating the genes for CAR-CD19, IL-15 and inducible caspase-9-based suicide gene (iC9), and demonstrated efficient killing of CD19-expressing cell lines and primary leukemia cells in vitro, with marked prolongation of survival in a xenograft Raji lymphoma murine model. Interleukin-15 (IL-15) production by the transduced CB-NK cells critically improved their function. Moreover, iC9/CAR.19/IL-15 CB-NK cells were readily eliminated upon pharmacologic activation of the iC9 suicide gene. In conclusion, we have developed a novel approach to immunotherapy using engineered CB-derived NK cells, which are easy to produce, exhibit striking efficacy and incorporate safety measures to limit toxicity. This approach should greatly improve the logistics of delivering this therapy to large numbers of patients, a major limitation to current CAR-T-cell therapies.

Background. To prospectively examine the urinary toxicity and quality of life (QOL) in patients 15 years after external beam radiotherapy (EBRT) for localized prostate cancer (LPC) and compare the outcomes with results for age-matched controls. Material and methods. Urinary symptoms were assessed using the symptom-specific Prostate Cancer Symptom Scale (PCSS) questionnaire, and QOL was assessed with the European Organization for Research and Treatment of Cancer (EORTC)'s Quality of Life Questionnaire (QLQ-C30). Both questionnaires were sent to the surviving 41 patients (25%) and the PCSS questionnaire was sent to 69 age-matched controls for comparison. Results. The response rate was 71% in the patient group and 59% in the control group. Two patients and four controls were excluded due to other cancer diagnoses, resulting in a total of 27 patients and 37 controls for inclusion in the analyses. The mean age in both groups was 78 years. In the patient group, incontinence had increased between the 8-year (mean=0.6) and the 15-year follow-up (mean=2.1; p=0.038). No other differences in urinary problems were seen between these two follow-ups. Increased incontinence, stress incontinence, and pain while urinating were reported by the patients in comparison with the controls at 15 years. Role function was worse in the patient group (mean=67.3) compared with the controls (mean=82.4; p=0.046). The patients also reported more appetite loss, diarrhea, nausea/vomiting, and pain than the controls. Conclusion. EBRT for LPC has divergent effects on urinary symptoms and QOL in comparison with age-matched controls. In our patient population, urinary incontinence increased between 8 and 15 years of follow-up. Otherwise, no differences in urinary symptoms were seen between 4 and 15 years. Incontinence, stress incontinence, and pain while urinating were increased after EBRT in comparison with the controls. Conventional EBRT did not result in a major deterioration in QOL 15 years after

Three-nucleon transfer reactions and cluster structure in the A = 15 to A = 19 nuclei

Martz, L.M.

1978-01-01

The ( 6 Li,t) and ( 6 Li, 3 He) reactions were studied on targets of 12 C, 13 C, 14 N, 15 N, and 16 O at E/sub Li/ approx. = 44 MeV and theta/sub lab/ approx. = 15 0 . A preferential population of final states was exhibited in spectra for the A = 15 to A = 19 nuclei. The strong forward peaking of angular distributions in the 13 C( 6 Li,t) 16 O and 13 C( 6 Li, 3 He) 16 N reactions can be reproduced by DWBA calculations but not by the Hauser-Feshbach model. Such indications of a primarily direct mechanism at forward angles suggest use of these three-nucleon-transfer reactions to identify candidates for 3p-nh states. A comparison with other multinucleon transfer data, e.g., those from ( 7 Li,α) and ( 7 Li,t) reactions on 13 C and 15 N targets, further tests dominant particle-hole configurations. The relationship between ( 6 Li,t) and ( 6 Li, 3 He) spectra reveals analog states, notably T = 1, T/sub z/ = 0 levels at high excitation in 16 O. Nuclear theory is used to investigate the role of triton clustering in such structure. The 2N + L = 6 band predicted by a folded-potential model of 18 O = 15 N + t shows an underlying correspondence to the experimental levels in triton-transfer data. Triton spectroscopic factors calculated from the SU(3) shell model further suggest the broad influence of clustering phenomena in this mass region. Experimental evidence of systematic behavior in the triton binding energies of proposed p/sup -n/(sd) 3 configurations was found

The use of kaurane diterpenes as substrates in fungal biotransformation to achieve bioactive compounds has been widely reported. In this work, the natural product kaurenoic acid, a diterpene widely distributed in the plant Kingdom, was chemically converted into ent-15α-hydroxy-kaur-16-en-19-oic acid (1). Substrate 1 was subjected to biotransformation by the fungus Fusarium proliferatum, furnishing a new derivative, ent-2α,15α-dihydroxy-kaur-16-en-19-oic acid (2). The structure of metabolite 2 was deduced on the basis of spectroscopy and MS data. Derivative 2 showed allelopathic activity on germination and growth of root and stem of lettuce (Lactuca sativa), inhibiting 100% of germination and growth of roots and stem, at higher concentration assayed (10 -4  mol/L).

Full Text Available There is a gap in knowledge about the mechanisms of sports-related brain injuries. The objective of this study was to determine the mechanisms of brain injuries among children and youth participating in team sports.We conducted a retrospective case series of brain injuries suffered by children participating in team sports. The Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP database was searched for brain injury cases among 5-19 year-olds playing ice hockey, soccer, American football (football, basketball, baseball, or rugby between 1990 and 2009. Mechanisms of injury were classified as "struck by player," "struck by object," "struck by sport implement," "struck surface," and "other." A descriptive analysis was performed.There were 12,799 brain injuries related to six team sports (16.2% of all brain injuries registered in CHIRPP. Males represented 81% of injuries and the mean age was 13.2 years. Ice hockey accounted for the greatest number of brain injuries (44.3%, followed by soccer (19.0% and football (12.9%. In ice hockey, rugby, and basketball, striking another player was the most common injury mechanism. Football, basketball, and soccer also demonstrated high proportions of injuries due to contact with an object (e.g., post among younger players. In baseball, a common mechanism in the 5-9 year-old group was being hit with a bat as a result of standing too close to the batter (26.1% males, 28.3% females.Many sports-related brain injury mechanisms are preventable. The results suggest that further efforts aimed at universal rule changes, safer playing environments, and the education of coaches, players, and parents should be targeted in maximizing prevention of sport-related brain injury using a multifaceted approach.

2009-08-15

The present prospectively designed 15-year longitudinal research was conducted to study whether locus of control is linked to diagnosis, to major symptoms, to functioning and recovery, and to personality for schizophrenia patients, depressive patients, and patients with other major disorders. The research studied 128 patients from the Chicago Follow-up Study at the acute phase and reassessed them 5 times over a 15-year period. Patients were evaluated on locus of control, global outcome, recovery, premorbid developmental achievements, psychosis, diagnosis, depression, and personality variables. 1) After the acute phase, schizophrenia patients were not more external than other diagnostic groups. 2) Internality is significantly associated with increased recovery in schizophrenia. 3) A more external locus of control was significantly related to depression. 4) The relationship between externality and psychosis was significant. In severe psychiatric disorders a more external locus of control is not specific to schizophrenia and after the acute phase is not associated with one particular diagnostic group. A more external locus of control is significantly related to fewer periods of recovery, to both depressed mood and psychosis, and to various aspects of personality.

Astrophysical x-ray bursts are thought to be a result of thermonuclear explosions on the atmosphere of an accreting neutron star. Between these bursts, energy is thought to be generated by the hot CNO cycles. The 15 O(α,γ) 19 Ne reaction is one reaction that allows breakout from these CNO cycles and into the rp-process to fuel outbursts. The reaction is expected to be dominated by a single 3/2 + resonance at 4.033 MeV in 19 Ne, however, limited information is available on this key state. This work reports on a pioneering study of the 20 Ne(p,d) 19 Ne reaction, performed in inverse kinematics at the experimental storage ring (ESR) as a means of accessing the astrophysically important 4.033 MeV state in 19 Ne. The unique, background free, high luminosity conditions of the storage ring were utilized for this, the first transfer reaction performed at the ESR. The results of this pioneering test experiment are presented along with suggestions for future measurements at storage ring facilities. (paper)

Many studies have shown that individual lifestyle factors are associated with cardiovascular mortality and all-cause mortality. Observational studies of comprehensive programmes have reported risk reductions. The objectives were to assess the long-term all-cause mortality by diagnosis in patients referred to a lifestyle modification programme, aimed at combating coronary heart disease and stroke. A randomized trial with 325 patients referred to the centre between 1988 and 1989 for dyslipidemia, hypertension, type 2 diabetes and coronary heart disease; 239 patients were randomized to the programme, 86 randomized to usual care. Cases were admitted to the centre in groups of 30 for a 4-week residential comprehensive activity, in total 114 full-time hours, focusing on food preferences and selections, and physical exercise. The activities were repeated during a 4-day revisit to the centre 1 year and 5 years after the 4-week intervention. Controls were referred back to their doctors, mainly in primary care, for usual care. Main outcome measure was all-cause mortality during 11–12 and 18–19 years after intervention. At follow-up 11–12 years after referral, the relative risk reduction (RRR) was 76% with the intention-to-treat analysis among cases admitted for dyslipidemia (hazards ratio 0.24, confidence interval 0.06–0.89, P = 0.033). After 18–19 years, the RRR was 66% (hazards ratio 0.34, confidence interval 0.13–0.88, P = 0.026). No RRR was found for the other three diagnoses. Patients admitted for dyslipidemia reached a real long-term RRR of all-cause mortality. They had by definition a need for this programme.

Social anxiety and alcohol use across the university years: Adaptive and maladaptive groups.

University/college can be a challenging time as students face developmental tasks such as building new social networks and achieving academically. Social anxiety may be disadvantageous in this setting given that social situations often include drinking and individuals with social anxiety tend to self-medicate through alcohol use. However, findings are mixed as to whether the association between social anxiety and alcohol use is positive or negative. To clarify the nature of this association, we used a person-centered longitudinal analysis to identify student groups based on levels of social anxiety symptoms and alcohol consumption. Undergraduates (N = 1132, 70.5% female, Mage = 19.06 at Time 1) enrolled in university completed a survey assessing social anxiety and alcohol use over 3 years, and psychosocial functioning and emotion coping behaviors at Time 1. Two out of 5 groups were identified with higher levels of social anxiety, 1 with moderately low alcohol use, and the other with moderately high alcohol use. Both groups reported higher levels of general anxiety, depressive symptoms, behavioral inhibition, emotional reactivity, daily hassles, and lower levels of social ties at Time 1 than the 3 groups with lower levels of social anxiety. Furthermore, the social anxiety-alcohol use group reported significantly lower academic grades and was more likely to endorse problematic emotion coping behaviors (e.g., self-injury) than the social anxiety-low alcohol use group. These results not only help explain the mixed findings in the literature but indicate that 1 group of socially anxious students may be particularly vulnerable to negative adjustment difficulties.

Summary Record of the 15th Meeting of the Working Group on Risk Assessment (WGRISK)

International Nuclear Information System (INIS)

2015-01-01

The main mission of the working group on risk assessment (WGRISK) is to advance the understanding and utilisation of probabilistic safety assessment (PSA) in ensuring the continued safety of nuclear installations in member countries. While PSA methodology has matured greatly over the years, further work is required. WGRISK has been active in several of these areas, including: human reliability; software reliability; low power and shutdown risk. In order to maintain a current perspective, the working group collaborates and assists other working groups within the CSNI, such as operating experience and organisational factors as well as keeping close co-ordination with other international organisations. Over the past twenty years, the NEA PWG5 and now WGRISK have looked at the technology and methods used for identifying contributors to risk and assessing their importance. Work during much of this period was concentrated on Level-1 PSA methodology. In recent years the focus has shifted into more specific PSA methodologies and risk-informed applications. This document summarizes the content of the 15. Meeting of WGRISK: - presentation of the new WGRISK Bureau, - Approval of the 14. WGRISK Meeting Summary Record [NEA/SEN/SIN/WGRISK (2013)1], - Use and Development of PSA in NEA Member Countries and by other International Organisations, - Report by the WGRISK Secretariat on the current WGRISK programme of work, actions taken by CSNI and CNRA and other recent developments in OECD/NEA, - Development of BPGs on failure mode taxonomy for reliability assessment of digital I and C systems for PSA [Task 2010-3], - Update Use of OECD Data Project Products in PSA [Task 2011-1], - Status report on the common WGHOF/WGRISK HRA Task, - Outcome on the International Workshop on PSA of Natural External Hazards Including Earthquakes, April 2014 [Task 2012-1], - Status report on the International Workshop on Fire PRA [Task 2012-2], - PSA insights relating to the loss of electrical sources

Background. To prospectively examine the urinary toxicity and quality of life (QOL) in patients 15 years after external beam radiotherapy (EBRT) for localized prostate cancer (LPC) and compare the outcomes with results for age-matched controls. Material and methods. Urinary symptoms were assessed using the symptom-specific Prostate Cancer Symptom Scale (PCSS) questionnaire, and QOL was assessed with the European Organization for Research and Treatment of Cancer (EORTC)'s Quality of Life Questionnaire (QLQ-C30). Both questionnaires were sent to the surviving 41 patients (25%) and the PCSS questionnaire was sent to 69 age-matched controls for comparison. Results. The response rate was 71% in the patient group and 59% in the control group. Two patients and four controls were excluded due to other cancer diagnoses, resulting in a total of 27 patients and 37 controls for inclusion in the analyses. The mean age in both groups was 78 years. In the patient group, incontinence had increased between the 8-year (mean=0.6) and the 15-year follow-up (mean=2.1; p=0.038). No other differences in urinary problems were seen between these two follow-ups. Increased incontinence, stress incontinence, and pain while urinating were reported by the patients in comparison with the controls at 15 years. Role function was worse in the patient group (mean=67.3) compared with the controls (mean=82.4; p=0.046). The patients also reported more appetite loss, diarrhea, nausea/vomiting, and pain than the controls. Conclusion. EBRT for LPC has divergent effects on urinary symptoms and QOL in comparison with age-matched controls. In our patient population, urinary incontinence increased between 8 and 15 years of follow-up. Otherwise, no differences in urinary symptoms were seen between 4 and 15 years. Incontinence, stress incontinence, and pain while urinating were increased after EBRT in comparison with the controls. Conventional EBRT did not result in a major deterioration in QOL 15 years

To investigate underlying conditions of patients with elevated CA 19-9 at screening tests and to evaluate diagnostic performance of abdominopelvic CT. One hundred and thirteen patients with elevated CA 19-9 (>37 U/ml) who underwent abdominopelvic CT in a screening program were selected. Underlying conditions were determined by reviewing all available data and follow-up records. Patients were categorized into malignancy, benign, and normal/non-related disease groups. Their mean CA 19-9 and percent of patients with CA 19-9 ≥ 100 U/ml were compared. Diagnostic sensitivity of CT for detecting underlying conditions of elevated CA 19-9 was analysed. Seventeen patients (17/113, 15 %) had 17 elevated CA 19-9-related malignancies, and 55 patients (55/113, 48.7 %) had 70 benign diseases. Mean CA 19-9 and percent of patients with CA 19-9 ≥ 100 U/ml in the malignancy group were significantly higher than in the two other groups. CT detected all except one malignant lesion with a detection sensitivity of 94.1 % (16/17). Of 70 CA 19-9-related benign diseases, CT detected 34 benign diseases (48.6 %) providing an alternative diagnosis for elevated CA 19-9. Abdominopelvic CT is not only useful in detecting malignancies, but can also diagnose alternative benign causes of elevated CA 19-9 in asymptomatic screening tests. (orig.)

This study examined the experiences of women who lived and worked on remote and isolated Antarctic stations for up to 15 months at a time. The study employed purposeful sampling and a longitudinal - processual approach to study women's experiences over the first 15 years of mixed gender Antarctic expeditions. The retrospective analysis was based on a semi-structured interview administered to 14 women upon their return to Australia. The results showed that women referred to the natural physical Antarctic environment as one of the best aspects of their experience and the reason they would recommend the Antarctic to their friends as a good place to work. In describing the worst aspect of their experience, women referred to aspects of Antarctic station life, including: (i) the male dominated nature of station culture; (ii) the impact of interpersonal conflict, including gender based conflict and friction between scientists and trades workers; and (iii) the lack of anonymity associated with living and working with the same group of individuals, mainly men, for up to 12 months or more. The results are discussed within the context of the evolution of Antarctic station culture and recommendations are made in terms of the demography of expeditions, expeditioner selection and recruitment and the ongoing monitoring of Antarctic station culture. The study presents a framework that can be applied to groups and teams living and working in analogous isolated, confined and extreme work environments, including outer space missions.

Diverse Effects of a Seven-Year Experimental Grassland Fragmentation on Major Invertebrate Groups.

Directory of Open Access Journals (Sweden)

Brigitte Braschler

Full Text Available Habitat fragmentation is a major driver of biodiversity loss, but observed effects vary and may depend on the group examined. Time since fragmentation may explain some differences between taxonomical groups, as some species and thus species composition respond with a delay to changes in their environment. Impacts of drivers of global change may thus be underestimated in short-term studies. In our study we experimentally fragmented nutrient-poor dry calcareous grasslands and studied the response of species richness, individual density and species composition of various groups of invertebrates (gastropods, ants, ground beetles, rove beetles, orthoptera, spiders, woodlice in 12 small (1.5 m * 1.5 m and 12 large (4.5 m * 4.5 m fragments and their corresponding control plots after 7 years. We further examined responses to fragmentation in relation to body size and habitat preferences. Responses to fragmentation varied between taxonomical groups. While spider species richness and individual density were lower in fragments, the opposite was true for an orthopteran species and woodlice. Species composition and β-diversity differed between fragments and control plots for some groups. However, the interaction treatment*plot size was rarely significant. Species with high occupancy rates in undisturbed control plots responded more negatively to the fragmentation, while species with large body size were relatively more abundant in fragments in some groups. No effect of the fragmentation was found for ants, which may have the longest lag times because of long-lived colonies. However, relationships between abundance and the species' preferences for environmental factors affected by edge effects indicate that ant diversity too may be affected in the longer-term. Our results show the importance of considering different groups in conservation management in times of widespread fragmentation of landscapes. While species richness may respond slowly, changes in

However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective.Purpose: To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors.Methods: A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80. The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants. The discussions were analyzed using content analysis.Results: The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available.Conclusion: On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward.

Full Text Available Clopidogrel is an antiplatelet drug especially used in patients undergoing percutaneous coronary interventions (PCI. Polymorphisms within CYP2C19 can result in important interindividual variations regarding therapeutic efficacy. Therefore, we aimed to evaluate the impact of the CYP2C19⁎2 variant (rs4244285 on in-stent restenosis occurrence in Chilean patients who underwent PCI and received clopidogrel. A total of 77 cases with stenosis >50% in the angioplasty site (62.75 ± 9.8 years, 80.5% males and 86 controls (65.45 ± 9.8 years, 72.1% males were studied. The polymorphism was genotyped using TaqMan® Drug Metabolism Genotyping Assays. Overall, CYP2C19⁎2 allele frequency was 8.3%. Diabetes, chronic lesions, and bare metal stents (BMS were observed more often in cases than in controls (p = 0.05, p = 0.04, and p = 0.02, resp.. Genotypic frequencies did not differ significantly between the groups (p = 0.15. Nonetheless, the mutated allele was observed in a greater proportion in patients without in-stent restenosis (p = 0.055. There was no significant association between the rs4244285 variant and the occurrence of in-stent restenosis after PCI (OR = 0.44; 95% CI: 0.19 to 1.04; p = 0.06. In summary, no association was identified between the CYP2C19⁎2 variant and the development of coronary in-stent restenosis.

Aluminium was measured in 2580 samples of 15 food groups and dietary exposure was estimated. Samples were purchased and analysed during 2010 to 2014. High aluminium levels were found in jellyfish (mean 4862 mg/kg), laver (mean 455.2 mg/kg) and fried twisted cruller (mean 392.4 mg/kg). Dietary exposure to aluminium was estimated for Zhejiang residents. The average dietary exposure to aluminium via 15 food groups in Zhejiang Province was 1.15 mg/kg bw/week, which is below the provisional tolerable weekly intake of 2 mg/kg bw /week. Jellyfish is the main Al contributor, providing 37.6% of the daily intake via these 15 food groups. This study provided new information on aluminium levels and assessment of aluminium (Al) dietary exposure in Zhejiang Province of China.

Analyses of children and young people mortality continue to be an important component of health monitoring of this population. Such analyses provide the basis to assess the overall trends, the structure of the causes of death over longer periods, and the differences between Poland and other countries. The purpose of the current study is to present the current status and the direction of changes since 2000 with regard to the level and underlying causes of mortality in children and adolescents aged 1-19 years in Poland on the background of statistics for leading European countries. Interactive databases available online: the National Demographic Database provided by the Central Statistical Office and the International WHO-MDB Database were used. Poland, constantly belonging to Eur-B category, was compared with the combined group of 27 leading countries, classified as a very low total mortality group (Eur-A) according to WHO. Linear trends of overall and cause-specific mortality in 2000-2013 were estimated. The causes of death have been presented according to the main classes of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). External and other causes were adopted as the two principal categories. In 2015, 1471 deaths of persons aged 1-19 were recorded in Poland (19.9 per 100 000, 25.4 and 14.2 for boys and girls, respectively). Changes in children and adolescents mortality by age have a non-linear nature (U-shaped), and the lowest level is recorded at the age of 5-9 years. According to 2014 data, 50.2% of deaths of children and adolescents aged 1-19 years occurred due to external causes, including non-intentional and intentional ones. This percentage increased from 18.4% in the 1-4 age group to 68.6% at the age of 15-19 years. Apart from external causes, the dominating causes of death are malignant neoplasms, congenital defects, or nervous system and respiratory system diseases. The ranking of those

Full Text Available OBJECTIVE: To verify the effectiveness of the support group in the identification of family variables linked to epilepsy. METHOD: Pre-test were applied to parents of 21 children with benign epilepsy of childhood recently diagnosed, from 5 to 15 years, who participated in the groups at HC/Unicamp. There was a presentation of an educational video, discussion and application of the post-test 1. After six months, the post-test 2 was applied. RESULTS: The beliefs were: fear of swallowing the tongue during the seizures (76.19% and of a future mental disease (66.67%. Facing the epilepsy, fear and sadness appeared. 76.19% of the parents presented overprotection and 90.48%, expected a new seizure. In the post-test 1, the parents affirmed that the information offered had modified the beliefs. In the post-test 2, 80.95% didn't report great doubts about epilepsy and 90.48% considered their relationship with their children better. CONCLUSIONS: The demystification of beliefs supplied from the groups influenced the family positively, prevented behavior alterations and guaranteed effective care in the attendance to the child with epilepsy.

Full Text Available OBJECTIVE: To analyze the prevalence of IgG antibodies to human parvovirus B19. METHODS: Cross-sectional study in a suburban community in São Paulo, Southeastern Brazil, between November 1990 and January 1991. Randomly selected (N=435 representative samples of sera were collected from healthy children older than 15 days old and adults up to 40 years old. IgG antibodies were detected using ELISA. RESULTS: High prevalence of IgG antibodies to B19 parvovirus was found in 87% of newborns. The prevalence of maternally derived IgG antibodies exponentially plunged up to the 19th month of age. Low prevalence of antibodies was found in the first 4 years of life, increasing up to 72% in those aged 31-40 years. It was estimated that the average age of first infection in this population is 21 ± 7 years old and the optimal age for vaccination with a hypothetical vaccine would be 1 year of age. CONCLUSIONS: Parvovirus B19 IgG antibody prevalence was high in newborns and those aged 31-40 years. The analysis by age groups showed a pattern similar to that found in previous studies, i.e., low prevalence of infection in children that increases with age.OBJETIVO: Analisar a prevalência de anticorpos IgG ao parvovírus humano B19.

Prevalence of periodontitis among the adolescents aged 15-18 years in Mangalore City: An epidemiological and microbiological study

Directory of Open Access Journals (Sweden)

K Pallavi Nanaiah

2013-01-01

Full Text Available Background: Periodontitis is a group of inflammatory diseases affecting the supporting tissues of the tooth. Both aggressive periodontitis (AP and chronic periodontitis (CP have a multifactorial etiology, with dental plaque as the initiating factor. However, the initiation and progression of periodontitis are influenced by other factors including microbiologic, social and behavioral and systemic and genetic factors. The prevalence of periodontal diseases varies in different regions of the world according to the definition of periodontitis and the study population, and there are indications that they may be more prevalent in developing than in developed countries. Materials and Methods: A cross-sectional study was conducted among the adolescents of 15-18 years of age in Mangalore City. One thousand one hundred students aged 15-18 years were selected for the study from the schools and colleges in Mangalore City using a convenient sampling method. The prevalence of AP and CP were assessed in the study using a community periodontal index. Students who were diagnosed clinically and radiographically were subjected to microbiological examination to confirm AP. Results: A high prevalence of gingivitis and periodontitis was found in students belonging to the lower socioeconomic status group compared with the higher socioeconomic groups, which were associated with poor oral hygiene habits. The prevalence of AP was found to be 0.36% and that of CP was found to be 1.5%. Conclusion: Oral diseases have a significant impact on the social and psychological aspects of an individual′s life. Exposure to risk factors, such as age, low socio-economic status, poor education, low dental care utilization, poor oral hygiene levels, smoking, psychosocial stress and genetic factors are significantly associated with an increased risk of periodontitis among adolescents. Although genetic factors play a major role in periodontitis, the treatment outcome will still be

Congenital central nervous system abnormalities in children with Fanconi anemia are poorly characterized, especially with regard to specific genetic complementation groups. To characterize the impact of genetic complementation groups on central nervous system anatomy. Through chart review we identified 36 patients with Fanconi anemia with available brain MRIs at the University of Minnesota (average age, 11.3 years; range, 1-43 years; M:F=19:17), which we reviewed and compared to 19 age- and sex-matched controls (average age, 7.9 years; range, 2-18 years; M:F=9:10). Genotypic information was available for 27 patients (15 FA-A, 2 FA-C, 3 FA-G, and 7 FA-D1 [biallelic mutations in BRCA2 gene]). Of the 36 patients, 61% had at least one congenital central nervous system or skull base abnormality. These included hypoplastic clivus (n=12), hypoplastic adenohypophysis (n=11), platybasia (n=8), pontocerebellar hypoplasia (n=7), isolated pontine hypoplasia (n=4), isolated vermis hypoplasia (n=3), and ectopic neurohypophysis (n=6). Average pituitary volume was significantly less in patients with Fanconi anemia (P<0.0001) than in controls. Basal angle was significantly greater in Fanconi anemia patients (P=0.006), but the basal angle of those with FA-D1 was not significantly different from controls (P=0.239). Clivus length was less in the Fanconi anemia group (P=0.002), but significance was only observed in the FA-D1 subgroup (P<0.0001). Of the seven patients meeting criteria for pontocerebellar hypoplasia, six belonged to the FA-D1 group. Patients with Fanconi anemia have higher incidences of ectopic neurohypophysis, adenohypophysis hypoplasia, platybasia and other midline central nervous system skull base posterior fossa abnormalities than age- and sex-matched controls. Patients with posterior fossa abnormalities, including pontocerebellar hypoplasia, are more likely to have biallelic BRCA2 mutations. (orig.)

Congenital central nervous system abnormalities in children with Fanconi anemia are poorly characterized, especially with regard to specific genetic complementation groups. To characterize the impact of genetic complementation groups on central nervous system anatomy. Through chart review we identified 36 patients with Fanconi anemia with available brain MRIs at the University of Minnesota (average age, 11.3 years; range, 1-43 years; M:F=19:17), which we reviewed and compared to 19 age- and sex-matched controls (average age, 7.9 years; range, 2-18 years; M:F=9:10). Genotypic information was available for 27 patients (15 FA-A, 2 FA-C, 3 FA-G, and 7 FA-D1 [biallelic mutations in BRCA2 gene]). Of the 36 patients, 61% had at least one congenital central nervous system or skull base abnormality. These included hypoplastic clivus (n=12), hypoplastic adenohypophysis (n=11), platybasia (n=8), pontocerebellar hypoplasia (n=7), isolated pontine hypoplasia (n=4), isolated vermis hypoplasia (n=3), and ectopic neurohypophysis (n=6). Average pituitary volume was significantly less in patients with Fanconi anemia (P<0.0001) than in controls. Basal angle was significantly greater in Fanconi anemia patients (P=0.006), but the basal angle of those with FA-D1 was not significantly different from controls (P=0.239). Clivus length was less in the Fanconi anemia group (P=0.002), but significance was only observed in the FA-D1 subgroup (P<0.0001). Of the seven patients meeting criteria for pontocerebellar hypoplasia, six belonged to the FA-D1 group.

Dysmenorrhea is a menstrual disorder with the greatest prevalence followed by premenstrual syndrome that includes physical and psychological symptoms. Micronutrients intake of calcium and magnesium can help overcome these complaints. This research was conducted to find out the effect of calcium and magnesium supplements consumption on dysmenorrhea and premenstrual syndrome symptoms in 19–23 years old women. This was quasi experimental research with pre- and post-test design. The research was conducted in Maranatha Christian University Bandung from July to December 2016. The subjects of research were 60 women aged 19–23 years old, divided into two groups randomly. One group given calcium (1,000 mg/day or magnesium (250 mg/day, which was given at the second day of menstruation until the next menstrual cycle. Serum levels of calcium or magnesium were measured with spectrophotometry method. Dysmenorrhea was measured with visual analog scale (VAS, whereas score of premenstrual syndrome was measured with shortened premenstrual assessment form, before and after treatment. The consumption of calcium lowers the VAS score average on dysmenorrhea from 6.97 to 3.80 (p=0.000** and the mean score of premenstrual syndrome from 15.07 to 10.80 (p=0.000**. Consumption of magnesium reduces the VAS score average on dysmenorrhea from 7 to 4 (p=0.000** and the mean score of premenstrual syndrome from 12.27 to 9.87 (p=0.001**. In conclusion, consumption of calcium or magnesium supplements reduce dysmenorrhea and premenstrual syndrome in women aged 19–23 years old.

The prevalence of waterpipe tobacco smoking is increasing globally and is associated with adverse outcomes requiring tobacco control interventions. We estimated the prevalence of waterpipe tobacco use among adult populations in Vietnam in 2010 and examined its association with sociodemographic factors. We used data from the Global Adult Tobacco Survey (GATS) conducted in Vietnam in 2010. GATS surveyed a national representative sample of adults aged 15 years or older from 11,142 households by using a 2-phase sampling design analogous to a 3-stage stratified cluster sampling. Descriptive statistical analyses and multivariate logistic regression modeling were conducted. A total of 6.4% of Vietnamese aged 15 years or older (representing about 4.1 million adult waterpipe smokers) reported current waterpipe tobacco smoking. The prevalence of waterpipe tobacco smoking was significantly higher among men than women (13% vs 0.1%). Area of residence (rural or urban), age group, asset-based wealth quintile, and geographic region of residence were significantly associated with waterpipe tobacco smoking among men. The significant correlates of current waterpipe tobacco smoking among men were lower education levels, being middle-aged (45-54 years), lower asset-based wealth levels, living in rural areas, not living in the South East and the Mekong River Delta geographic regions, and the belief that smoking does not causes diseases. Rural dwellers who are poor should be targeted in tobacco control programs. Further studies are needed that examine perceptions of the adverse health effects and the cultural factors of waterpipe tobacco smoking.

In 1964, The Melbourne Asthma Study was established to describe the spectrum and natural history of childhood asthma. To describe the clinical and lung function outcome of childhood asthma to the age of 50 years. Subjects were invited to complete an interviewer-administered questionnaire, skin prick testing, and measurement of lung function from the age of 7 years to the age of 50 years at 7-year intervals. Of 458 survivors (from the original 484 subjects at recruitment), 346 subjects (76%) participated, of whom, 197 completed lung function measurement. Asthma remission at the age of 50 years was 64% in those with wheezy bronchitis, 47% for those with persistent asthma, and 15% for those with severe asthma in childhood. Multivariable analysis identified severe asthma in childhood (odds ratio [OR] 11.9 [95% CI, 3.4-41.8]), female sex (OR 2.0 [95% CI, 1.1-3.6]), and childhood hay fever (OR 2.0 [95% CI, 1.0-4.0]) as risk factors for "current asthma" at age 50 years. There was no evidence of a difference in the rate of decline in FEV1 (mL/y, 95% CI) between the severe asthma group (15 mL/y [95% CI, 9-22 mL/y]) and all the other recruitment groups: control (16 mL/y [95% CI, 12-20 mL/y]), mild wheezy bronchitis (14 mL/y [95% CI, 8-19 mL/y]), wheezy bronchitis (16 mL/y [95% CI, 11-20 mL/y]), and persistent asthma (19 mL/y [95% CI, 13-24 mL/y]). The clinical and lung function outcome in adult life is strongly determined by asthma severity in childhood. The reduced lung function seen in adults is established in childhood and does not appear to decline more rapidly in adult years despite continuing symptoms.

Demirjian's method has been the most popular and extensively tested radiographic method of age estimation. More recently, Willems' method has been reported to be a better predictor of age. Nolla's and Häävikko's methods have been used to a lesser extent. Very few studies have compared all four methods in non-Indian and Indian populations. Most Indian research is limited by inadequate sample sizes, age structures and grouping and different approaches to statistical analysis. The present study aimed to evaluate and compare the validity of the Demirjian, Willems, Nolla and Häävikko methods in determination of chronological age of 5 to 15 year-old Indian children. In this cross-sectional observational study, four methods were compared for validity in estimating the age of 1200 Indian children aged 5-15 years. Demirjian's method overestimated age by +0.24 ± 0.80, +0.11 ± 0.81 and +0.19 ± 0.80 years in boys, girls and the total sample, respectively. With Willems' method, overestimations of +0.09 ± 0.80, +0.08 ± 0.80 and +0.09 ± 0.80 years were obtained in boys, girls and the total sample, respectively. Nolla's method underestimated age by -0.13 ± 0.80, -0.30 ± 0.82 and -0.20 ± 0.81 years in boys, girls and the total sample, respectively. Häävikko's method underestimated age by -0.17 ± 0.80, -0.29 ± 0.83 and -0.22 ± 0.82 years in boys, girls and the total sample, respectively. Statistically significant differences were observed between dental and chronological ages with all methods (p age, followed by Demirjian's, Nolla's and Häävikko's methods. All four methods could be applicable for estimating age in the present population, mean prediction errors being lower than 0.30 years (3.6 months).

Effect of heat treatment on the microstructure change and mechanical properties for the Ni-19Si-3Nb-0.15B intermetallic alloy

International Nuclear Information System (INIS)

Jang, J.S.C.; Chang, L.J.

2003-01-01

The microstructural change of the Ni-19Si-3Nb-0.15B alloys after different heat treatment was examined by scanning electron microscopy with energy dispersive spectrum. In addition, Vickers's hardness test was used to measure the variation of mechanical properties for each heat-treated alloy. The results reveal that the typical dendritic microstructure of the heat-treated alloys (comprised of dendritic β-phase, α-β eutectic, and the Nb-rich precipitates) remained almost the same microstructure as the as-cast alloy. However, the morphology of the sharp-edged Nb-rich precipitate (identified to be the cubic Nb 3 Ni 2 Si by electron diffraction of TEM) would be blunted by homogenization. In addition, the size of precipitates seemed to grow with increased aging temperature and aging time. Correlating the result of microhardness measurement with the microstructure observation, an aging temperature of 700 deg. C and an aging time of 10 h is found to be the optimum treating condition for the Ni-19Si-3Nb-0.15B alloy. In addition, the precipitate growth is revealed dominating by an interfacial-controlled kinetics with a thermal activation process of Arrhenius type. The strengthening effect of the heat treatment is not obvious from the hardness test. However, the effect of heat treatment exhibited significant improvement on the ductility of the Ni-19Si-3Nb-0.15B alloy (ε ∼3% for as-cast alloy and 12% for heat-treated alloy)

Full Text Available Background: There is sparse literature that provides evidence of cervical and shoulder postural alignment of 15 to 17-year-old adolescents and that analyzes sex differences. Objectives: To characterize the postural alignment of the head and shoulder in the sagittal plane of 15 to 17-year-old Portuguese adolescents in natural erect standing and explore the relationships between three postural angles and presence of neck and shoulder pain. Method: This cross-sectional study was conducted in two secondary schools in Portugal. 275 adolescent students (153 females and 122 males aged 15 to 17 were evaluated. Sagittal head, cervical, and shoulder angles were measured with photogrammetry and PAS software. The American Shoulder and Elbow Surgeons Shoulder Assessment (ASES was used to assess shoulder pain, whereas neck pain was self-reported with a single question. Results: Mean values of sagittal head, cervical, and shoulder angles were 17.2±5.7, 47.4±5.2, and 51.4±8.5º, respectively. 68% of the participants revealed protraction of the head, whereas 58% of them had protraction of the shoulder. The boys showed a significantly higher mean cervical angle, and adolescents with neck pain revealed lower mean cervical angle than adolescents without neck pain. 53% of the girls self-reported regular neck pain, contrasting with 19% of the boys. Conclusions: This data shows that forward head and protracted shoulder are common postural disorders in adolescents, especially in girls. Neck pain is prevalent in adolescents, especially girls, and it is associated with forward head posture.

A 45 year old female who received radiotherapy for stage II-B uterine cervical cancer four and half years ago, presented with persistent hematuria due to radiation cystitis. 15(S) 15-methyl prostaglandin F 2 -alpha (1 mg in 100 ml of normal saline) was instilled into the bladder daily for two days. The severity of bleeding decreased considerably. However, significant hematuria recurred 19 days later which continued despite bladder irrigation with normal saline, 1 mg of 15(S) 15-Me PGF 2 alpha mixed with hydroxyethyl cellulose gel to a volume of 10 ml was then instilled into the urinary bladder daily for three days and macroscopic hematuria ceased. Urinary frequency and urgency were the side effects which lasted for ten days. There has been no recurrence of macroscopic hematuria during the five months followup. In conclusion, 15(S) 15-Me PGF 2 - alpha may be administered intravesically to control moderate hematuria due to radiation cystitis. (author). 5 refs

To assist in the long-term health management of residents and evaluate the health impacts after the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to implement the Fukushima Health Management Survey. This report describes the results for residents aged 15 years or younger who received health checks and evaluates the data obtained from 2011 and 2012. The target group consisted of residents aged 15 years or younger who had lived in the evacuation zone. The health checks were performed on receipt of an application from any of the residents. The checks, which included the measurements of height, weight, blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required. 1) A total of 17,934 (64.5%) and 11,780 (43.5%) residents aged 15 years or younger received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 7-15 year age group were found to suffer from obesity, hyperlipidemia, hyperuricemia, or liver dysfunction. Furthermore, pediatric aged 15 years or younger were commonly observed to suffer from hypertension or glucose metabolic abnormalities. 3) A comparison of data from 2012 and 2011 demonstrated that both males and females frequently showed increased body height and decreased body weight in 2012. The prevalence of hypertension, glucose metabolic abnormalities, or high γ-GTP values in males and females in the 7-15 year age group in 2012 was lower than that in 2011. However, the prevalence of hyperuricemia among residents in the 7-15 year age group was higher in 2012 than in 2011. These results suggested that some residents aged 15 years or under who had lived in the evacuation zone had developed obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, or glucose metabolic abnormalities. Therefore, we think that it is necessary to continue the health

A case of Parvovirus B19 infection (erythema infectiosum) in a 20 year old woman is presented. The patient presented with fever, arthritis in one knee, neutrophil granulocytosis and biochemical evidence of hepatitis. Serological evidence of Parvovirus B19 infection was found as the only explanation of the clinical picture. Hepatitis was due to Parvovirus B19 infection as there was no serological evidence of EBV or CMV reactivation. Neutrophil granulocytosis and thrombocytosis were found and were probably due to an active bone marrow in the recovery phase of bone marrow aplasia.

2018-05-01

To establish the prevalence of external (EAS) and internal (IAS) anal sphincter defects present 15-24 years after childbirth according to mode of delivery, and their association with development of fecal incontinence (FI). The study additionally aimed to compare the proportion of women with obstetric anal sphincter injuries (OASIS) reported at delivery with the proportion of women with sphincter defect detected on ultrasound 15-24 years later. This was a cross-sectional study including 563 women who delivered their first child between 1990 and 1997. Women responded to a validated questionnaire (Pelvic Floor Distress Inventory) in 2013-2014, from which the proportion of women with FI was recorded. Information about OASIS was obtained from the National Birth Registry. Study participants underwent four-dimensional transperineal ultrasound examination. Defect of EAS or IAS of ≥ 30° in at least four of six slices on tomographic ultrasound was considered a significant defect and was recorded. Four study groups were defined based on mode of delivery of the first child. Women who had delivered only by Cesarean section (CS) constituted the CS group. Women in the normal vaginal delivery (NVD) group had NVD of their first child and subsequent deliveries could be NVD or CS. The forceps delivery (FD) group included women who had FD, NVD or CS after FD of their first born. The vacuum delivery (VD) group included women who had VD, NVD or CS after VD of their first born. Multiple logistic regression was used to calculate adjusted odds ratios (aORs) for comparison of prevalence of an EAS defect following different modes of delivery and to test its association with FI. Fisher's exact test was used to calculate crude odds ratios (ORs) for IAS defects. Defects of EAS and IAS were found after NVD (n = 201) in 10% and 1% of cases, respectively, after FD (n = 144) in 32% and 7% of cases and after VD (n = 120) in 15% and 4% of cases. No defects were found after CS (n�

Full Text Available Two hundred consecutive cases up to 19 years of age admitted for confinement at The Nowrosjee Wadia Maternity Hospital, Bombay, were studied. Out of these 200 girls, 6 were unmarried, 51 were anaemic, 20 had toxaemia of pregnancy. Six girls (43% in the age group 15-17 years delivered prematurely as compared to only 26 girls (14% in the age group of 17-19 years. This difference is statistically significant. Also, only, 4 girls (29% in the age group of 15-17 years had full term normal delivery as compared to 113 girls (61% in the age group of 17-19 years signifying that the outcome of pregnancy becomes worst in girls below the age of 17 years. Ten babies (71% of mothers in the age group of 15-17 years were LBW as compared to 75 babies (44% of mothers in the age group of 17-19 years signifying that the incidence of LBW babies is inversely proportional to maternal age. Teenage pregnant girls needed more attention for prevention and treatment of preeclampsia eclampsia, anaemia, prematurity and LBW.

The aim of this study was to investigate the relation between health-related physical fitness and weight status in 13- to 15-year-old Latino adolescents. The final sample consisted of 73,561 adolescents aged 13-15 years (35,175 girls) from Chile (n=48,771) and Colombia (n=24,790). Cardiorespiratory and musculoskeletal fitness were measured using 20-m shuttle run (relative peak oxygen uptake - VO 2peak ) and standing broad jump test (lower body explosive strength), respectively. The International Obesity Task Force definition was used to define weight status (i.e., underweight, normal weight, overweight, and obese). The present study found an inverted J-shape relationship between body mass index, cardiorespiratory fitness, and musculoskeletal fitness in both genders and all age groups (pfitness (based on new international criterion-referenced standards) profile when compared with their normal weight peers, except in girls aged 14 (p=0.268) and 15 years (p=0.280). The present results indicate low cardiorespiratory fitness and musculoskeletal fitness levels in underweight, overweight, and obese adolescents when compared with their normal weight peers. The findings appear to suggest that exercise programs should to decrease fat mass in overweight/obese adolescents and increase muscle mass in underweight adolescents.

Treatment results of glioblastoma (GB) during the last 30 years in Tohoku University were analyzed to identify any improvements in patient outcome in all 332 histologically proven cases of newly diagnosed GB treated consecutively in our department between 1982 and 2011. These 30 years was divided into 5 treatment eras, Group 1 (1982-1988, without preoperative evaluation by magnetic resonance [MR] imaging, n=46), Group 2 (1989-1996, with preoperative MR imaging, n=41), Group 3 (1997-1999, additionally underwent intraoperative functional brain mapping and neuronavigation system, n=38), Group 4 (2000-August 2006, underwent 30 Gy of whole brain radiation followed by 30 Gy of extended local accelerated hyperfractionated radiation therapy, n=96), and Group 5 (September 2006-2011, adjuvant usage of temozolomide [TMZ], n=111). Overall survival (OS) was calculated from the date of surgery to the death from any cause. The median survival time/2-year OS/5-year OS of Groups 1 to 5 were 10.7 months/10.9%/0%, 17.3 months/26.2%/6.9%, 15.9 months/23.7%/5.3%, 20.1 months/34.8%/15.5%, and 20.9 months/45.5%/19.7%. The prognosis for patients with GB improved significantly after the introduction of MR imaging. Younger GB, defined as patients aged below 60 years, or total tumor resection with all ages in Group 5 had 5-year OS of 31.0% and 30.1%, respectively. The prognosis of GB was improved significantly after the introduction of TMZ for elderly GB, recursive partitioning analysis class 5, or totally resected GB. Introduction of MR imaging and TMZ, and total resection of the tumor were important in the improvement of outcome for patients with GB. (author)

Full Text Available Background: Congenital anomalies (CAs are a leading cause of fetal and infant mortality and morbidity worldwide. They may be identified prenatally, at the moment of birth or later in life.Purpose: To describe the cases of CAs registered over the last 15 years at a level III hospital, comparing individuals who were detected through prenatal (preN diagnosis with those detected through postnatal (postN diagnosis.Methods: All records were collected from the Registo Nacional de Anomalias Congénitas (RENAC online platform between 1st January 2000 to 31st December 2014, in a level III hospital, where cases of CAs were notified voluntarily (n = 1,222. We tested differences for selected variables between the years in study. A multivariate analysis was performed to identify potential factors associated to preN diagnosis.Results: We observed a total of 1,510 anomalies, being 493 (40.3% circulatory, 252 (20.6% chromosomal, 187 (15.3% musculoskeletal, 138 (11.3% digestive, 133 (10.9% urinary, 117 (9.6% nervous, 37 (3.0% respiratory, 35 (2.9% genital, 25 (2% anomalies of the eye, ear, face and neck, 20 (1.6% cleft lip/cleft palate and 73 (6.0% others. Time of diagnosis was known for all subjects: 770 (63.0% were diagnosed prenatally and 452 (37.0% were diagnosed at birth or during the first month of life. We found statistically significant differences between groups for several variables. Assisted reproduction techniques (p = 0.023, maternal medications during the first trimester of pregnancy (p = 0.004 and the number of anomalies per individual (p ≤ 0.001 had a statistically significant impact on receiving preN diagnosis.Conclusion: Our data confirm the importance of both RENAC national database and preN diagnosis in improving perinatal healthcare. However, in order to determine the national prevalence of CAs and understand any involved factors, it is desirable to enhance the notification in the whole country, facilitating the adjustment of national

This cross-sectional study compared the caries experience in 15-year-olds with and without demarcated hypomineralised lesions (DHL) in permanent teeth. One thousand three hundred and two 15-year-old adolescents from two ongoing birth cohorts (GINIplus15 and LISAplus15) were examined to determine non-cavitated carious lesions (NCCL) and the DMF index. Furthermore, DHL was scored on all permanent teeth/surfaces according to the molar-incisor hypomineralisation criteria of the European Academy of Paediatric Dentistry (MIH/EAPD). Adolescents with DHL were categorised into those with a minimum of one DHL in the permanent dentition (DHL ≥ 1), with DHL on at least one first permanent molar (MIH/EAPD) and with DHL on at least one first permanent molar and permanent incisor (MIH/Severe). The study was conducted in the metropolitan area of Munich. The proportion of children without caries amounted to 63.7% (DMF > 0) and 26.0% (D 1-4 MF > 0); the caries experience was mean = 4.0(SD = 5.2) NCCL/T and 0.9(1.7) DMF/T. Existence of DHL ≥ 1, MIH/EAPD and MIH/Severe was detected in 40.2, 17.2 and 9.8% of all adolescents, respectively. The corresponding DMF/T values were: no DHL 0.9(1.7); DHL ≥ 1 1.0(1.7); MIH/EAPD 1.1(1.6); MIH/Severe 1.1(1.7). The group of adolescents with MIH/EAPD and MIH/Severe were found to have statistically higher caries rates in comparison to those with no DHL. Caries and DHL are prevalent and influenced the dental health of 15-year-old adolescents. A significant positive association existed between the presence of caries and DHL. Children with MIH/EAPD or MIH/Severe had a higher probability to develop carious lesions in the permanent dentition.

To assess the dental caries, periodontal health, and malocclusion of school children aged 12 and 15 years in Shimla city and to compare them in government and private schools. A cross-sectional study of 12- and 15-year-old children in government and private schools was conducted in Shimla city, Himachal Pradesh, India. A sample of 1011 school children (both males and females) was selected by a two-stage cluster sampling method. Clinical recordings of dental caries and malocclusion were done according to World Health Organization diagnostic criteria 1997. Periodontal health was assessed by Community Periodontal Index of Treatment Needs index. The data collected was analyzed by SPSS package 13. The statistical tests used were t-test and Chi-square tests. The prevalence of dental caries was 32.6% and 42.2% at 12 and 15 years, respectively. At the12 years of age, the mean decayed, missing, filled teeth was 0.62 ± 1.42 and it was 1.06 ± 2.93 at 15 years of age. Females had higher level of caries than males at both the ages. At both ages, mean of decayed teeth was statistically higher in government schools as compared with private schools. Children in government schools had significantly less number of mean filled teeth at both ages as compared with private schools. The healthy component of gingiva was present in higher percentage of children in private schools as compared with government schools at both the age groups. The prevalence of malocclusion among the 12- year-old (58.1%) was more as compared with that among the 15-year-old (53.5%). The caries experience of 12- and 15-year-old children was low but the prevalence of gingivitis and malocclusion was quite high. Effective oral health promotion strategies need to be implemented to improve the oral health of school children further in Shimla city.

A low-intensity armed conflict has been occurring for nearly a decade in southernmost region of Thailand. However, its impact on child health has not yet been investigated. This study aimed to estimate the prevalence of delayed child growth and development in the affected areas and to determine the association between the violence and health among children aged 1-5 years. A total of 498 children aged 1-5 years were recruited. Intensity of conflict for each sub-district was calculated as the 6-year average number of incidents per 100,000 population per year and classified into quartiles. Growth indices were weight-for-age, height-for-age, and weight-for-height, while development was measured by the Denver Development Screening Test II (Thai version). Food insecurity, child-rearing practice, health service accessibility, household sanitation, and depression among the caregivers were assessed using screening scales and questionnaires. Contextual information such as average income and numbers of violent events in each sub-district was obtained from external sources. Growth retardation was highly prevalent in the area as reported by rates of underweight, stunting, and wasting at 19.3%, 27.6% and 7.4%, respectively. The prevalence of developmental delay was also substantially high (37.1%). Multi-level analysis found no evidence of association between insurgency and health outcomes. However, children in areas with higher intensity of violence had a lower risk of delay in personal-social development (OR = 0.4; 95% CI = 0.2 - 0.9; p-value = 0.05). Unlike war refugees and internally-displaced persons in camp-like settings, the relationship between level of armed conflict and growth and developmental delay among children aged 1-5 years could not be demonstrated in the community setting of this study where food supply had been minimally perturbed.

The normalisation of cannabis use among young people: Symbolic boundary work in focus groups

2011-01-01

This paper analyses ‘techniques of neutralisation’ among young people discussing cannabis in focus group interviews. The paper is based on data from focus group interviews with young Danes followed from when they were 14–15 years old in 2004 until they were 18–19 years old in 2008. In this period......, the participants’ attitudes towards cannabis undergo a radical change from being negative and sceptical into being predominantly positive and accepting; a change we describe as a ‘normalisation’ of cannabis use. Four techniques of neutralisation are identified in this process. First, the participants redefine...... the setting of cannabis use, simultaneously creating a new type of togetherness: relaxed social intoxication. Second, the effects of cannabis use are transformed from being ‘strange’ and ‘unpredictable’ to being ‘controllable’ by the individual user. Third, participants change their classification of cannabis...

Full Text Available To present a 19-year experience of the prognosis of patients with acute myocardial infarction (AMI and prior coronary artery bypass surgery (CABS, 748 patients with AMI after prior CABS (postbypass group and a control group of 1080 patients with AMI, but without prior CABS, were analyzed. All indexes of infarct size were lower in the postbypass group. There was more ventricular fibrillation in the postbypass group. In-hospital mortality was similar (p = 0.3675. In the follow-up period, postbypass patients had more heart failure, recurrent CABS, reinfarction, and unstable angina than did control patients. Cumulative survival was better in the control group than in the postbypass group (p = 0.0403. Multiple logistic regression model showed that previous angina (p = 0.0005, diabetes (p = 0.0058, and age (p = 0.0102 were independent predictor factors for survival. Use of digitalis and diuretics, together with previous angina, also influenced survival (p = 0.0092, as well as male gender, older patients, and diabetes together (p = 0.0420. Patients with AMI after prior CABS had smaller infarct, but more reinfarction, reoperation, heart failure, and angina. Previous angina, diabetes, and age, independently, as well as use of digitalis and diuretics together with angina, and male gender, older patients, and diabetes together, influenced a worse survival rate in these patients.

This study compared the effectiveness of three approaches to improving visual perception among preschool children 4-6 years old with developmental delays: multimedia visual perceptual group training, multimedia visual perceptual individual training, and paper visual perceptual group training. A control group received no special training. This study employed a pretest-posttest control group of true experimental design. A total of 64 children 4-6 years old with developmental delays were randomized into four groups: (1) multimedia visual perceptual group training (15 subjects); (2) multimedia visual perceptual individual training group (15 subjects); paper visual perceptual group training (19 subjects); and (4) a control group (15 subjects) with no visual perceptual training. Forty minute training sessions were conducted once a week for 14 weeks. The Test of Visual Perception Skills, third edition, was used to evaluate the effectiveness of the intervention. Paired-samples t-test showed significant differences pre- and post-test among the three groups, but no significant difference was found between the pre-test and post-test scores among the control group. ANOVA results showed significant differences in improvement levels among the four study groups. Scheffe post hoc test results showed significant differences between: group 1 and group 2; group 1 and group 3; group 1 and the control group; and group 2 and the control group. No significant differences were reported between group 2 and group 3, and group 3 and the control group. The results showed all three therapeutic programs produced significant differences between pretest and posttest scores. The training effect on the multimedia visual perceptual group program and the individual program was greater than the developmental effect Both the multimedia visual perceptual group training program and the multimedia visual perceptual individual training program produced significant effects on visual perception.

The paper describes an experience of online-publication of Russian archival materials by means of two web-GIS projects. The first project is devoted to publication of the collection of the earliest Russian cartographic drawings (mainly 2nd half of the 17th century), which cover a significant part of Russian territory, mainly the European part (http://rgada.info/geos2). Most of them have never been published and were not easily accessible for scholars and users due to poor physical condition. We tried to combine opportunities of geocoding of the picture with capacity to use an authentic image. The second project offers the results of localization of toponyms and land parcels from various documents (15-19th cc.) connected with one region of the Russian State called Bezhetsk Upland (http://rgada.info/bezheck/popup.html). These results were arranged in the set of layers which may be combined by the user.

The aim and objective of the present study was to determine the prevalence and severity of gingivitis and evaluate the factors associated with gingivitis in children residing in rural and urban areas of Panchkula. The present study was carried out on a sample of 1269 school children, aged 5, 12 and 15 years, randomly selected from the rural and the urban schools of Panchkula and gingival index was recorded as devised by Loe and Silness (1963) to assess the severity of gingivitis. A standardized questionnaire was self prepared, which was filled by the examiner prior to the clinical examination. The data were subjected to SPSS, version 13, and statistically analyzed using Chi test, F test, ANOVA test. In the age group of 5 years, the children affected with gingivitis in the rural and the urban areas were 67 and 33%, respectively, which was statistically highly significant (P = 0.0001). In the age group of 12 years, the children affected with gingivitis in the rural and the urban areas were 94 and 92%, respectively (P = 0.537), whereas in 15-year olds, the children affected with gingivitis in the rural and the urban areas were 98 and 64%, respectively (P = 0.0001). The children who brushed once a day had higher prevalence of gingivitis as compared to children who brushed more than once per day in all the age groups. The results showed that the percentage of children affected with gingivitis was significantly higher in the rural areas in 5- and 15-year-old children, but this trend was not seen in 12-year age group, reflecting the lack of awareness in rural areas.

Purpose: Long-term biochemical relapse-free survival (BRFS) rates in patients with clinical Stages T1-T3 prostate cancer continue to be scrutinized after treatment with external beam radiation therapy and brachytherapy. Methods and Materials: We report 15-year BRFS rates on 223 patients with clinically localized prostate cancer that were consecutively treated with I 125 or Pd 103 brachytherapy after 45-Gy neoadjuvant EBRT. Multivariate regression analysis was used to create a pretreatment clinical prognostic risk model using a modified American Society for Therapeutic Radiology and Oncology consensus definition (two consecutive serum prostate-specific antigen rises) as the outcome. Gleason scoring was performed by the pathologists at a community hospital. Time to biochemical failure was calculated and compared by using Kaplan-Meier plots. Results: Fifteen-year BRFS for the entire treatment group was 74%. BRFS using the Memorial Sloan-Kettering risk cohort analysis (95% confidence interval): low risk, 88%, intermediate risk 80%, and high risk 53%. Grouping by the risk classification described by D'Amico, the BRFS was: low risk 85.8%, intermediate risk 80.3%, and high risk 67.8% (p = 0.002). Conclusions: I 125 or Pd 103 brachytherapy combined with supplemental EBRT results in excellent 15-year biochemical control. Different risk group classification schemes lead to different BRFS results in the high-risk group cohorts

The mortality rate of young offenders is high. Furthermore, mortality in young offenders is associated with psychiatric and substance use disorders. The primary aim of this national register-based follow-up study was to investigate the mortality rate of Finnish delinquents who underwent a forensic psychiatric examination between 1980 and 2010. As delinquency is not a solid entity, we further aimed to compare the risk of premature death among different subgroups of the delinquents; violent versus non-violent offenders, offenders with alcohol use disorders versus those with no such diagnoses, offenders with schizophrenia spectrum disorders versus conduct- and personality-disordered offenders, under-aged versus young adult offenders, and, finally, boys versus girls. We collected the forensic psychiatric examination reports of all 15- to 19-year-old offenders who were born in Finland and had undergone the examination between 1.1.1980 and 31.12.2010 (n = 606) from the archives of the National Institute of Health and Welfare and retrospectively reviewed them. For each delinquent, four age-, gender- and place of birth-matched controls were randomly selected from the Central Population Register (n = 2424). The delinquents and their controls were followed until the end of 2015. The median follow-up time was 23.9 years (interquartile range 15.3-29.5). We obtained the mortality data from the causes of death register. Deaths attributable to a disease or an occupational disease were considered natural, and those attributable to an accident, suicide or homicide were considered unnatural. By the end of the follow-up period, 22.1% (n = 134) of the delinquents and 3.4% (n = 82) of their controls had died (OR 8.11, 95% CI 6.05-10.86, p delinquents and 3.7% (n = 81) of the controls had died (OR 7.38, 95% CI 5.46-9.95, p delinquents' risk of unnatural death was almost 11-fold, of natural death more than twofold, and of unclear death more than fourfold compared to that of

Full Text Available Abstract Introduction Temporal bone paragangliomas (TBPs are benign tumors arising from neural crest cells located along the jugular bulbus and the tympanic plexus. In general surgical excision, radiotherapy and wait-and-scan protocols are the main management modalities for TBPs. Objective In this paper we aim to present our clinical experience with TBPs and to review literature data. Methods The patients who were operated for tympanomastoid paraganglioma (TMP or tympanojugular paraganglioma (TJP in our clinic in the last 15 years were enrolled in the study. A detailed patient's charts review was performed retrospectively. Results There were 18 (52.9% cases with TMPs and 16 (47.1% cases with TJPs, a total of 34 patients operated for TBPs in this time period. The mean age was 50.3 ± 11.7 (range 25-71 years. The most common presenting symptoms were tinnitus and hearing loss for both TMPs and TJPs. Gross total tumor resection was achieved in 17 (94.4% and 10 (62.5% cases for TMPs and TJPs, respectively. Five patients (31.2% with TJP experienced facial palsy following the operation. For all the patients the mean follow-up period was 25.8 months (range 4-108 months. Conclusion In conclusion, based on our findings and literature review, total surgical excision alone or with preoperative embolization is the main treatment modality for TBPs. However radiotherapy, observation protocol and subtotal resection must be considered in cases of preoperative functioning cranial nerves, large tumors and advanced age.

Temporal bone paragangliomas (TBPs) are benign tumors arising from neural crest cells located along the jugular bulbus and the tympanic plexus. In general surgical excision, radiotherapy and wait-and-scan protocols are the main management modalities for TBPs. In this paper we aim to present our clinical experience with TBPs and to review literature data. The patients who were operated for tympanomastoid paraganglioma (TMP) or tympanojugular paraganglioma (TJP) in our clinic in the last 15 years were enrolled in the study. A detailed patient's charts review was performed retrospectively. There were 18 (52.9%) cases with TMPs and 16 (47.1%) cases with TJPs, a total of 34 patients operated for TBPs in this time period. The mean age was 50.3± 11.7 (range 25-71 years). The most common presenting symptoms were tinnitus and hearing loss for both TMPs and TJPs. Gross total tumor resection was achieved in 17 (94.4%) and 10 (62.5%) cases for TMPs and TJPs, respectively. Five patients (31.2%) with TJP experienced facial palsy following the operation. For all the patients the mean follow-up period was 25.8 months (range 4-108 months). In conclusion, based on our findings and literature review, total surgical excision alone or with preoperative embolization is the main treatment modality for TBPs. However radiotherapy, observation protocol and subtotal resection must be considered in cases of preoperative functioning cranial nerves, large tumors and advanced age.

Peer-assisted learning (PAL) has become a well-accepted teaching method within medical education. However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective. To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors. A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80). The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants). The discussions were analyzed using content analysis. The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available. On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward. The tutor-student working alliance acts through its flat hierarchy. Nevertheless, tutors cannot represent an adequate substitute for experienced physicians.

Background: Fluoride is a double edged sword. The assessment of dental caries and fluorosis in endemic fluoride areas will facilitate in assessing the relation between fluoride concentrations in water with dental caries, dental fluorosis simultaneously. Aim: The objective of the following study is to assess the dental caries and dental fluorosis prevalence among 12 and 15-year-old school children in Nalgonda district, Andhra Pradesh, India. Subjects and Methods: This was a cross-sectional study. Two stage cluster sampling technique was employed to select 20 schools from Nalgonda district. The oral examination of available 12 and 15-year-old children fulfilling the inclusion and exclusion criteria was carried out to assess dental caries and fluorosis. The examination was conducted by a single trained and calibrated examiner using the mouth mirror and community periodontal index probe under natural daylight. These areas were divided into four categories, low, medium, high and very high fluoride areas based on the fluoride concentration at the time of statistical analysis. The data was analyzed using Statistical Package for the Social Sciences version 16 (IBM, Chicago, USA). Results: The caries prevalence was less among 12-year-old children (39.9% [369/924]) compared with 15-years-old children (46.7% [444/951]). The prevalence was more among females (50.4% [492/977]) than males (35.8% [321/898]). The prevalence was more in low fluoride area (60.5% [300/496]) followed by very high fluoride area (54.8% [201/367]), high fluoride area (32.4% [293/904]) and medium fluoride area (17.6% [19/108]) in the descending order. The fluorosis prevalence increased with increasing fluoride concentration with no difference in gender and age distribution. Conclusion: Low fluoride areas require fluoridation or alternate sources of fluoride, whereas high fluoride areas require defluoridation. Defluoridation of water is an immediate requirement in areas with fluoride concentration of 4

Between January of 1987 and December of 2001 were born 1243 twins related to 609 multiple pregnancies, in Maternidade Bissaya-Barreto. Data were grouped in periods of three years and several parameters were studied. The rate of multiple gestation has increased probably due to the contribution of the assisted conception techniques, and to the increase of the number of multiple fetal pregnancies (two or more) and to the increase of the mother age. These more frequent obstetric problems were preterm birth, gestational hypertension and abnormal sonographic data of fetal growth. The average age of delivery was 34 weeks and the birth weight has decreased. The most important factors for neonatal morbidity were hyaline membranous disease, intraventricular haemorrhage and the twin-twin transfusion syndrome. The neonatal mortality decreased in the last studied period.

METHODS This is a prospective population-based single centre observational study of all patients diagnosed with benign perforated peptic ulcer; included were both gastric and duodenal ulcer patients admitted to Maharaja Yeshwantrao Hospital, Indore, between September 2013 and September 2015. Ulcers with a malignant neoplasia diagnosis verified by histology after biopsy, traumatic perforation, and perforation of age group >45 and 40 years, the incidence increased over 4 times and mortality more than 12 times compared to younger age <20 years. After 1 month followup, out of 172 discharged patients, 145 (84% patients came with symptoms resolved or having no complication. After 2 months followup, 158 (92% patients came with symptoms resolved and 166 (96% patients changed their dietary habits and lifestyle. CONCLUSION The incidence rate and mortality rate was stable. In our study, we found male preponderance, may be due to their lifestyle changes. Maximum number patients are found in age group 41-45 years. As in all previous studies, as age advances, incidence of peptic perforation also increases. Also, found strong relationship between consumption of oily or spicy food and non-vegetarian food with incidence of peptic perforation. Relation of peptic perforation with NSAIDs, smoking, and alcoholism follows same trends as in previous studies.

Minnes, Sonia; Min, Meeyoung O; Short, Elizabeth J; Wu, Miaoping; Lang, Adelaide; Yoon, Susan; Singer, Lynn T

Prenatal exposure to cocaine (PCE) may alter areas of the brain dense with monoamine receptors such as the prefrontal cortex and negatively affect cognitive processes implicated in executive function (EF). This study investigated the effects of PCE on EF at 12 and 15years. EF was examined in 189 PCE and 183 non-cocaine exposed (NCE) children who were primarily African American and of low socioeconomic status. Caregivers rated their child on the Behavior Rating Inventory of Executive Function (BRIEF) at ages 12 and 15. The BRIEF includes two summary scales and eight subscales: Behavioral Regulation Index (BRI) (Inhibit, Shift, and Emotion) and Metacognition Index (MI) (Monitor, Working Memory, Plan/Organize, Organization of Materials and Task Completion). Two additional measures were included at age 15 (BRIEF Self-Report and the CANTAB Stockings of Cambridge (SOC)). Girls with PCE were perceived by caregivers to have more behavioral regulation problems at age 12 (p<0.005) and more metacognitive problems at age 12 (p<0.003) than NCE females, but there was no association for males. PCE girls improved in behavioral regulation (p<0.05) and metacognition (p<0.04) from 12 to 15years compared to NCE girls based on caregiver report. By self-report PCE was associated with problems of inhibition (p<0.006). Girls with PCE performed more poorly on number of moves to complete the SOC, requiring planning and problem solving, than NCE girls. Prenatally cocaine exposed girls were perceived by caregivers as having problems of behavioral regulation, and by self-report, inhibitory control problems. Girls with PCE also performed more poorly on a task of planning and problem solving at age 15 which corresponded to caregiver report at age 12. Early assessment and remediation of these weaknesses in girls may improve school performance and behavior associated with poor EF. Copyright © 2016. Published by Elsevier Inc.

Kamath, KP; Vidya, M

2015-01-01

Background: Although numerous investigators have studied the pattern of keratin expression in different odontogenic cysts, the results have been variable. Aim: The present study was conducted to determine the pattern of expression of cytokeratin 19 (CK 19) in the epithelial lining of odontogenic keratocysts and dentigerous cysts. Materials and Methods: The epithelial layers showing expression of the epithelial marker CK 19 was determined by immunohistochemical methods in 15 tissue specimens each of histopathologically confirmed cases of dentigerous cysts and odontogenic keratocysts. Statistical analysis was done to compare the CK 19 expression between dentigerous cyst and odontogenic keratocyst using the Chi-square test. P keratocysts, 40% (6/15) of the specimens were negative for CK 19, 40% (6/15) of the specimens showed expression only in a single layer of the epithelium, and 20% (3/15) of the specimens showed expression in more than one layer, but not the entire thickness of the epithelium. The observed differences in CK 19 expression by the two lesions were statistically significant (P < 0.01). Conclusion: The differences in CK 19 expression by these cysts may be utilized as a diagnostic tool in differentiating between these two lesions. PMID:25861531

Effect of perioperative inefficiency on neurosurgical theatre efficacy: A 15-year analysis.

Science.gov (United States)

Kamat, Ameya S; Parker, Andrew

2015-01-01

Effective utilisation of operating theatre time is an important issue in neurosurgery. There is a commonly held belief amongst surgeons that throughput of theatre is decreasing secondary to worsening perioperative delays. The aim of this paper is to explore some of the factors that lead to delays in the perioperative period by determining whether there has been a trend in the increasing length of case time over a fifteen-year period. Case notes of all elective patients who consented for surgery between January 1998 and the end of 2012 were reviewed. Only patients who underwent elective surgery were included. Variables recorded included transit time from the ward to theatre, anaesthetic time, surgical time and time spent in recovery. These were compared over the 15-year period to look for apparent trends. The total number of patients who consented for elective surgery at our institution between January 1998 and December 2012 was 6760. The mean anaesthetic time considering all operations performed was 43 mins each over the 15-year period. Anaesthetic time was deemed to be trending upwards from 1998 where the mean time was 27 -60 mins in December 2012, thus reflecting an increase of 33 mins. The mean surgical times over the 15-year period were 131 mins. However in 1998, mean surgical time was 127 mins compared with 133 mins in 2012. For the operations analysed, anaesthetic time seems to be increasing and has effectively doubled over a 15-year period. Surgical time and non-clinical time are shown to be virtually constant. This delays the overall theatre list and increases the cancellation rate. For compensating this, changes need to be made when allocating resources to both elective and emergency theatres. Staff recruitment needs to be assessed and internal audits need to be conducted within institutions to analyse ways to optimise the throughput of an operation theatre. If these principles are not adhered to, it will have a negative impact as our populations, and

Global co-existence of two evolutionary lineages of parvovirus B19 1a, different in genome-wide synonymous positions.

Directory of Open Access Journals (Sweden)

Marijke W A Molenaar-de Backer

Full Text Available Parvovirus B19 (B19V can cause infection in humans. To date, three genotypes of B19V, with subtypes, are known, of which genotype 1a is the most prevalent genotype in the Western world. We sequenced the genome of B19V strains of 65 asymptomatic, recently infected Dutch blood donors, to investigate the spatio-temporal distribution of B19V strains, in the years 2003-2009. The sequences were compared to B19V sequences from Dutch patients with fifth disease, and to global B19V sequences as available from GenBank. All Dutch B19V strains belonged to genotype 1a. Phylogenetic analysis of the strains from Dutch blood donors showed that two groups of genotype 1a co-exist. A clear-cut division into the two groups was also found among the B19V strains from Dutch patients, and among the B19V sequences in GenBank. The two groups of genotype 1a co-exist around the world and do not appear to differ in their ability to cause disease. Strikingly, the two groups of B19V predominantly differ in synonymous mutations, distributed throughout the entire genome of B19V. We propose to call the two groups of B19V genotype 1a respectively subtype 1a1 and 1a2.

Receptor dose and patient dose in radiographic exposures: a 15 year review

International Nuclear Information System (INIS)

Peet, D.J.; Tyler, N.; Pryor, M.; Hollaway, P.; Strudley, C.; Leavesley, L.

2008-01-01

A patient dose programme has been established locally for the last 15 years across 109 hospitals and 250 X-ray rooms in line with the National Protocol, in conjunction with a programme to look at routine performance of these rooms. Routine performance checks initially looked primarily at film density and AEC performance but with the introduction of Computerised Radiography (CR) across UK hospitals and a revision of recommended procedures in the UK, the emphasis has shifted to assessing receptor dose under AEC control. Results show a wide variation in film density in the early years indicating sub optimal performance and dose. The spread was reduced over later years. The introduction of CR has led to a variety of approaches by the CR companies, X-ray companies and local sites. Receptor doses vary widely as a result. Large variations within hospitals were also observed. The doses over the last 15 years are reviewed and compared against diagnostic reference levels and with the performance of the imaging chain. Results show that patient dose programmes and optimisation strategies were having an impact, but the introduction of CR requires renewed efforts to ensure images and doses are optimised. (author)

Full Text Available The association between increasing obesity and metabolic syndrome among adolescent and the adverse consequences in adulthood including type-2 diabetes and coronary heart disease is well documented. The main objectives of this study were to evaluate the major metabolic risk factors and some clinical important parameters in Syrian male adolescents (18-19 years old, and to assess the correlations between BF% determined by BIA-man prediction equation and metabolic risk factors in the same group. The correlations between body fat percentage (BF% based on BIA-man predictive equations, blood pressure, fasting blood sugar (FBS, cholesterol (Chol, low density lipoprotein cholesterol (LDL-C, high density lipoprotein cholesterol (HDL-C, triglycerides (TG, Hematocrit (Ht, and hemoglobin (Hb in 1596 healthy Syrian adolescents aged 18-19 years and the mean values of these parameters were examined. Data showed that, DBP, Chol, TG, LDL and TG/HDL-C were significantly (p<0.05 higher in overweight and obese subjects in compression to normal weight cases. Whereas, SBP, FBS and Ht were significantly (p<0.05 higher in obese subjects in compression to normal weight. However, all measured variable related to metabolic syndrome risk factors increased with increasing the BF% determined by BIA-man. The present study suggests that % BF by BIA-man is a good predictor of metabolic risks factors for Syrian adolescents.

Surgical management of meniscal lesion consists of either a meniscectomy or meniscal repair. Although repair offers immediate recovery after surgery, it is also associated with higher rates of revision. A meniscectomy, on the other hand is known to be associated with an early onset of osteoarthritis. The present study compared clinical and radiological results at 10 years between meniscectomy and meniscal repair in isolated vertical lesion in an otherwise stable knee. The hypothesis was that repair shows functional and radiological benefit over meniscectomy. A multi-centric retrospective comparative study of 32 patients (24 male, 8 female). Mean follow-up was 10.6 years (range, 10-13 years). There were 10 meniscal repairs (group R) and 22 meniscectomies (group M), in 17 right and 15 left knees. Mean age at surgery was 33.45±12.3 years (range, 9-47 years). There were 28 medial and 4 lateral meniscal lesions; 26 were in the red-red zone and 6 in red-white zone. Functional score: KOOS score was significantly higher in group R than M on almost all parameters: 98±4.69 versus 77.38±21.97 for symptoms (P=0.0043), 96.89±7.20 versus 78.57±18.9 for pain (P=0.0052), 99.89±0.33 versus 80.88±19.6 for daily life activities (P=0.0002), 96.11±9.83 versus 54.05±32.85 for sport and leisure (P=0.0005), but 91±16.87 versus 68.15±37.7 for quality of life (P=0.1048). Radiology score: in group R, 7 patients had no features of osteoarthritis, and 2 had grade 1 osteoarthritis. In group M, 5 patients had grade 1 osteoarthritis, 10 grade 2, 3 grade 3 and 3 grade 4. Mean quantitative score was 0 (mean, 0.22±0.44) in-group R and 2 (mean, 2.19±0.98) in group M (P<0.0001). At more than 10year's follow-up, functional scores were significantly better with meniscal repair than meniscectomy on all parameters of the KOOS scale except quality of life. Functional and radiological scores correlated closely. These results show that meniscal repair for vertical lesions in stable knees

Full Text Available Most developmental studies of emotional face processing to date have focussed on infants and very young children. Additionally, studies that examine emotional face processing in older children do not distinguish development in emotion and identity face processing from more generic age-related cognitive improvement. In this study, we developed a paradigm that measures processing of facial expression in comparison to facial identity and complex visual stimuli. The three matching tasks were developed (i.e., facial emotion matching, facial identity matching and butterfly wing matching to include stimuli of similar level of discriminability and to be equated for task difficulty in earlier samples of young adults. Ninety two children aged 5 to 15 years and a new group of 24 young adults completed these three matching tasks. Young children were highly adept at the butterfly wing task relative to their performance on both face-related tasks. More importantly, in older children, development of facial emotion discrimination ability lagged behind that of facial identity discrimination.

of January 1st, 2001 to December 31st, 2010. Demographic variables, epidemiological category, lesion topography, performed studies and treatment results were reviewed in the epidemiological surveys. Results: there was reported an incidence of 32 cases, with 8 and 6 cases in 2001 and 2010 respectively and rates of 8.6 and 4.9 per one hundred thousand 15-18 years old respectively. Males and age of 18 years prevailed, no association with race. The most affected municipalities were 10 de Octubre, Habana Vieja y Centro Habana. The students predominated (17-53.1 %, 5 of them in boarding schools; 9 were unemployed (28.1 % including 1 prisoner. The infecting contact was not found in most of the cases (20 cases, 62 %. Pulmonary form predominated (27 cases-84.4 % showing 44.4% of positive bacilloscopy. There was no co-infection with human immunodeficiency virus. All the patients received the strictly supervised treatment and they recovered, except for one death during the second week of treatment. Conclusions: it is necessary to delve into the factors having an effect on tuberculosis within this age group, as well as to assure more microbiological isolation and extensive search for the source of infection.

This study aimed to determine the role of tumor markers AFP, CA15-3, CA125, CA19-9 and CEA in patients with hepatitis B and C. This descriptive cross-sectional study was performed from Oct 2012 to Oct 2014. Serum samples of 129 patients with hepatitis B and C referred to Guilan Liver and Digestive Disease Research Center in Rasht, Iran were collected and checked for the existence of the listed tumor markers by ELISA. No increase in serum levels of tumor marker CA19-9, CEA and CA15-3 were seen in patients with hepatitis ( P >0.05). In patients with hepatitis B, increase in CA125 were observed ( P =0.03). In hepatitis C patients, there was an increase in AFP levels ( P =0.03). The levels of AFP and CA125 markers were high in hepatitis C and hepatitis B, respectively. However, the increased levels were not seen is malignancy. Due to the small sample size, further study is necessary to find the reasons of the increase.

Neutron stars in close binary star systems often accrete matter from their companion stars. Thermonuclear ignition of the accreted material in the atmosphere of the neutron star leads to a thermonuclear explosion which is observed as an X-ray burst occurring periodically between hours and days depending on the accretion rate. The ignition conditions are characterized by a sensitive interplay between the accretion rate of the fuel supply and its depletion rate by nuclear burning in the hot CNO cycle and the rp-process. For accretion rates close to stable burning the burst ignition therefore depends critically on the hot CNO breakout reaction 15 O(α, γ) 19 Ne that regulates the flow between the hot CNO cycle and the rapid proton capture process. Until recently, the 15 O(α, γ) 19 Ne reaction rate was not known experimentally and the theoretical estimates carried significant uncertainties. In this paper we perform a parameter study of the uncertainty of this reaction rate and determine the astrophysical consequences of the first measurement of this reaction rate. Our results corroborate earlier predictions and show that theoretically burning remains unstable up to accretion rates near the Eddington limit, in contrast to astronomical observations

The primary intention of this study is the grouping of sports accidents, being described by the athletes in their own words in a classification system of specific accident classes with regard to specific motions and topography. The investigation is based on the data of the sports insurance Gerling-Konzern during a 15-year period in Rhineland Palatinate (1981-1995). The study is based on the insurance documents and clinical protocols if available. 137 accident protocols were related to this 15-year period including weight lifting (n = 1) and martial arts (n = 136). Listed in hierarchical order we received the following results: judo (n = 47), karate (n = 44), wrestling (n = 22), taekwondo (n = 9), boxing (n = 7), ju-jutsu (n = 5), fencing (n = 1) and aikido (n = 1). In accordance to accident types there were no sex related differences. As special preventive measures we suggest the use of protective mouthguards and solid glasses, proprioceptive training and physiological taping for knee, ankle and elbow joints.

This study was to determine the prevalence of herniated intervertebral disc (HIVD) among Korean 19-year-old male in a large national sample and to compare the prevalence across geographic regions based on the data of conscription. We analyzed the conscription data of 615508 cases who were 19-year-old male, given an examination for conscription at nationwide Korean Military Manpower Administration from January 2008 to December 2009. Prevalence was determined by dividing the number of cases by the number of persons enrolled for 2 years. The analyses included of a cross-tabulations and nonparametric chi-square to compare the prevalence according to geographic region, disc severity, and conscription year. The prevalence of HIVD among 19-year-old male was 0.47%. Seoul had the highest prevalence of HIVD (total HIVD was 0.60%, and severe HIVD was 0.44%). The prevalence of HIVD was lower in Jeollabuk- do and Jeollanam-do (total HIVD was 0.25-0.27%, and severe HIVD was 0.16-0.17%). Annual prevalence of HIVD was slightly decreased in 2009, but geographic distribution annually was not different. In Korean 19-year-old male, the national prevalence of adolescent HIVD was 0.60%, but different geographic distribution was observed. It is quite possible that secondary contributing factor(s) interfere with the different geographic prevalence of HIVD.

Osteoarticular complications, which are characterized by osseous pain, pathologic fractures, and decreased articular mobility, represent one of the mayor problems affecting long-term (over 15 years) hemodialysis patients. These changes seem to have a multifactorial etiology; they include osteomalacia, secondary hyperparathyroidism, and dialysis-related amyloidosis. Ten patients (5 males and 5 females, mean age 55± 7 years) on long-term (over 15 years) hemodialysis were submitted to X-ray examinations of the skull, spine, shoulders, wrists, pelvis, and knees. Serum calcium, phosphorous, parathyroid hormone, alkaline phosphatase, and basal aluminium levels were also calculated. Osteopenia was demonstrated in all patients. Seven of them had alterations due to hyperparathyroidism. Six patients exhibited signs related to dialysis spondyloarthropathy; in 9 cases amyloid lesions, geodes, and erosions were present in wrists, humeral heads, or hips. One patients exhibited osteomalacic changes. Most long-terms dialysis patients presented multifactorial osteoarticular changes due to hyperparathyroidism, osteomalacia and dialysis-related amyloidosis. Clinical sympoms and decreased articular mobility appeared to be due mainly to amyloid osteoarthropathy

Background: This study assessed the radiation safety at Nuclear Medicine Department being a work environment. Ionizing radiation exposure of the employees in the last 19 years and the effects of legislative changes in radiological protection were analyzed. Material/Methods: All employees of the investigated department were regularly and individually monitored using chest badges equipped with Kodak film type 2. Overall, 629 annual doses of the employees of nuclear medicine department, registered in the period 1991 - 2009, were analyzed statistically. Results: Technicians were found to be the largest exposed professional group, whereas nurses received the highest annual doses. Physicians received an average annual dose at the border detection methods. Ancillary and administration staff occasionally received doses above the method detection limit (MDL). The average annual dose for all dosimetry records was 0.7 mSv, and that for dosimetry records equal and higher than MDL was 2.2 mSv. Conclusions: There was no case of an exceeded dose limit for a worker. Furthermore, improvement of radiological protection had a significant impact on the reduction of doses for the most exposed employees. (authors)

Full Text Available Competition activity of footballers is considered 19-21-years-old age in the professional commands of Europe. For research it was served as information normatively-legal documents of Federations of football of leading European championships (request letters and protocols of matches. In research it was necessary to be attached to the construction of the statistical groupings, that allowed to analyse in a dynamics playing activity of footballers on the stage of training to higher achievements. Influence of the competition loadings is appraised on the organism of sportsmen. Participating of sportsmen of this age is set in compositions of professional commands - leaders of rating of UEFA. It is set that the basic failing in preparation of the Ukrainian young footballers is surplus pursuit after a result and accent on physical preparation. It gives advantage above other commands which work above the technique of game (Holland, Germany, Spain in youth football. However, when players from youth football pass to the grown man, results sharply fall and felt substantial blanks in individual technical preparedness.

The aim of the present study was to compare and assess the oral health status of 12-year-old children from two socially disadvantaged groups in the Udupi district of South India. A total of 327 children were examined in Ashrama schools, and 340 children were randomly selected for comparison from other government schools. Modified WHO proforma was used for clinical examination. Oral hygiene practices, dental fluorosis, periodontal status, dentition status and dentofacial anomalies were assessed and compared. Chi square test was used for comparison between categorical variables and Mann-Whitney test for comparison between two groups for quantitative variables. P u 0.05 was considered as statistically significant. Dental fluorosis was detected in 22.9% children from Ashrama schools, whereas in the comparison group 14.4% children had dental fluorosis (P u 0.001). Mean Decayed teeth and DMFT value in Ashrama school children were 1.15 ± 1.62, and 1.15 ± 1.62, respectively. In the comparison group, the corresponding values were 0.46 ± 0.98 and 0.48 ± 1.04, respectively (P u 0.001). The mean number of sextants in the Ashrama school children with Community Periodontal Index score 2 was 2.00 ± 1.53, whereas in the comparison group it was 1.31 ± 1.53 (P u 0.001). No significant differences were noted between two groups with respect to Dental Aesthetic Index scores. The present study revealed higher levels of dental caries experience, untreated dental disease and social disadvantage of the children attending Ashrama schools, providing evidence for the need to address the health inequalities of these children.

Backwards and Forwards: 50 years of the Education Group

2000-01-01

The Education Group of the Institute of Physics celebrated its 50th anniversary by dedicating its annual 16 - 19 Day to a conference entitled Post-16 Physics: Looking forward, learning from the past. This attracted an audience of 50 or so nostalgia-seekers on Saturday 13 November at the Portland Place HQ. Philip Britton (Chair of the Education Group) began the proceedings in his usual pawky way by challenging members to identify the year in which some hardy topics were first addressed. A key trend in titles was the movement from problem to challenge . He looked forward to the time when success was a keynote word. Few identified Physics in Industry with the year of the deepest recession of the Thatcher Era. Tim Akrill (Chief A-level Physics Examiner for Edexcel) reminded us that A-levels were just about as old as the Education Group before taking us on an informative and entertaining tour of Assessment and Examinations through the Ages . Things have indeed become more complex since the very first written examination of 6th century China, when the only question, set every year, was: `Write down everything you know'. In 1951 an A-level physics paper gave a choice of six out of twelve questions and appeared in an A5 booklet of perhaps as many as four pages. The satisfying thump of a kilogram mass of current Edexcel A-level physics papers resounded through the room as he dropped them on a table. In those innocent days all questions followed the DDC format: define, describe, calculate . `Question spotting' was an art (or science) assiduously developed by teachers, as Lees' Disk alternated with Searle's Bar with less than exciting regularity. Have standards fallen? He thought not. At Edexcel they still get about 4000 candidates getting the higher grades, a number that has stayed the same for some 20 years. He singled out Nuffield Advanced Physics as being responsible for the greatest innovations in exam style since, well, the Chinese really. Styles such as Practical

Full Text Available A gram-scale synthesis of terminally-branched iso-fatty acids (iso-C12–C19 was developed commencing with methyl undec-10-enoate (methyl undecylenate (for iso-C12–C14 or the C15 and C16 lactones pentadecanolide (for iso-C15–C17 and hexadecanolide (for iso-C18–C19. Central to the approaches outlined is the two-step construction of the terminal isopropyl group through addition of methylmagnesium bromide to the ester/lactones and selective reduction of the resulting tertiary alcohols. Thus, the C12, C17 and C18 iso-fatty acids were obtained in three steps from commercially-available starting materials, and the remaining C13–C16 and C19 iso-fatty acids were prepared by homologation or recursive dehomologations of these fatty acids or through intercepting appropriate intermediates. Highlighting the synthetic potential of the iso-fatty acids and various intermediates prepared herein, we describe the synthesis of the natural products (S-2,15-dimethylpalmitic acid, (S-2-hydroxy-15-methylpalmitic acid, and 2-oxo-14-methylpentadecane.

Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age ≤ 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast

There is a paucity of information about the dental specialties related articles published in the Medical Journal Armed Forces India (MJAFI). This study aimed to audit the dental specialities related articles published in MJAFI from 2000 to 2014 over a 15-year period. Bibliometric analysis of sixty issues of MJAFI from 2000 to 2014 were performed using web-based search. The articles published were analyzed for type of article and topic of individual dental specialities. The articles published were also evaluated to identify whether the study was an Armed Forces Medical Research Committee Project or funded research project or not. Out of the total 118 published articles related to dental specialities, original articles (55) and case reports (49) contribute the major share. The highest number of dental specialities related articles was published in 2009 with 16, followed by 2010 with 13 and 2011 with 11 and the least published year was 2013 with 3 articles. Regarding the relationship with dental specialities, the maximum number of published articles were related to oral medicine and radiology (56) followed by oral and maxillofacial surgery (49), orthodontics (23) and prosthodontics (17). Among the articles published in MJAFI, maxillofacial injuries (11) followed by orthodontic treatment (8) and craniofacial deformities (8) form the major attraction of the contributors. Among the 118 dental speciality articles, there were only 4 Armed Forces Medical Research Committee Project articles and 19 funded research project articles. An equal distribution of articles related to clinical dentistry and nonclinical dentistry is maintained for the MJAFI from 2000 to 2014 over a 15-year period.

The cardiovascular risk (CVR) is increasing and it is related to life style and dietary habits; one of the age groups at risk of developing this disease are the obese children. The objective of this study was to assess the CVR in the obese pediatric population in a secondary care unit of the Instituto Mexicano del Seguro Social in San Luis Potosí, México. A cross-sectional study, in which we used Alústiza's scale to measure CVR. We included the total of cases of pediatric obese population in a year. We performed the analysis by each of the variables included in the scale (age, sex, body mass index, family history of diabetes and obesity, alcohol, blood pressure, cholesterol). High CVR was correlated to HDL and glucose, through a statistical analysis with chi-squared. We reviewed a total of 100 medical records of children from 6 to 15 years (52 girls, 48 boys). CVR was low in 26 %, moderate in 14 % and higher in 60 %. A positive history of obesity was found in 26 %; obesity plus diabetes, 16 %; obesity and dyslipidemia, 13 %; hypertension, 11 %. None of the children practiced excercise. We found hypercholesterolemia in 46 %, and hyperglycemia in 34 %. By using chi-squared we found that all variables were statistically significant (p < 0.05). Validated scales are useful to measure CVR in children, in order to take action in a timely fashion and avoid the persistence of risk in adulthood.

We report 15-year survival, clinical, and radiographic follow-up data for the Press-Fit Condylar Sigma total knee arthroplasty. Between October 1998 and October 1999, 235 consecutive TKAs were performed in 203 patients. Patients were reviewed at a specialist nurse-led clinic before surgery and at 5, 8-10, and 15 years postoperatively. Clinical outcomes, including Knee Society Score, were recorded prospectively at each clinic visit, and radiographs were obtained. Of our initial cohort, 99 patients (118 knees) were alive at 15 years, and 31 patients (34 knees) were lost to follow-up. Thirteen knees (5.5%) were revised; 5 (2.1%) for infection, 7 (3%) for instability, and 1 (0.4%) for aseptic loosening. Cumulative survival with the end point of revision for any reason was 92.3% at 15 years and with revision for aseptic failure as the end point was 94.4%. The mean Knee Society Score knee score was 77.4 (33-99) at 15 years, compared with 31.7 (2-62) preoperatively. Of 71 surviving knees for which X-rays were available, 12 (16.9%) had radiolucent lines and 1 (1.4%) demonstrated clear radiographic evidence of loosening. The Press-Fit Condylar Sigma total knee arthroplasty represents a durable, effective option for patients undergoing knee arthroplasty, with excellent survival and good clinical and radiographic outcomes at 15 years.

To investigate the clinical epidemiology change trend of upper gastrointestinal bleeding (UGIB) over the past 15 years. Consecutive patients who was diagnosed as continuous UGIB in the endoscopy center of The First Affiliated Hospital of Sun-Yat University during the period from 1 January 1997 to 31 December 1998 and the period from 1 January 2012 to 31 December 2013 were enrolled in this study. Their gender, age, etiology, ulcer classification, endoscopic treatment and hospitalization mortality were compared between two periods. In periods from 1997 to 1998 and 2012 to 2013, the detection rate of UGIB was 9.99%(928/9 287) and 4.49%(1 092/24 318)(χ 2 =360.089, P=0.000); the percentage of male patients was 73.28%(680/928) and 72.44% (791/1 092) (χ 2 =0.179, P=0.672), and the onset age was (47.3±16.4) years and (51.4±18.2) years (t=9.214, P=0.002) respectively. From 1997 to 1998, the first etiology of UGIB was peptic ulcer bleeding, accounting for 65.2%(605/928)[duodenal ulcer 47.8%(444/928), gastric ulcer 8.3%(77/928), stomal ulcer 2.3%(21/928), compound ulcer 6.8%(63/928)],the second was cancer bleeding(7.0%,65/928), and the third was esophageal and gastric varices bleeding (6.4%,59/928). From 2012 to 2013, peptic ulcer still was the first cause of UGIB, but the ratio obviously decreased to 52.7%(575/1092)(χ 2 =32.467, P=0.000)[duodenal ulcer 31.9%(348/1092), gastric ulcer 9.4%(103/1092), stomal ulcer 2.8%(30/1092), compound ulcer 8.6%(94/1092)]. The decreased ratio of duodenal ulcer bleeding was the main reason (χ 2 =53.724, P=0.000). Esophageal and gastric varices bleeding became the second cause (15.1%,165/1 092, χ 2 =38.976, P=0.000), and cancer was the third cause (9.2%,101/1 092, χ 2 =3.352, P=0.067). The largest increasing amplitude of the onset age was peptic ulcer bleeding [(46.2±16.7) years vs. (51.9±18.9) years, t=-5.548, P=0.000), and the greatest contribution to the amplitude was duodenal ulcer bleeding [(43.4±15.9) years vs. (48.4±19
