    The vitamin B6 status of high school students and its relationship with dietary intake were investigated in this cross-sectional study by face-to-face interview. A total of 157 healthy students aged 16-18 years (eighty-three boys and seventy-four girls) were randomly recruited from two out of nineteen senior high schools in Tainan, Taiwan. Vitamin B6 intakes were calculated from three 24-h dietary records. Direct and indirect vitamin B6 status indicators were measured in plasma, erythrocytes and urine. The anthropometric data, being similar to those of the first Nutrition and Health Survey in Taiwan (1993-1996), showed the normal growth and development of these students. All students except one girl (28.7 nmol/l) had plasma pyridoxal-5'-phosphate (PLP) levels >35 nmol/l, indicating an adequate vitamin B6 status. The mean dietary vitamin B6 intakes of boys and girls were 1.04 (sd 0.29) and 0.96 (sd 0.27) mg/d, respectively. Vitamin B6 status indicators, including plasma PLP, erythrocyte alanine aminotransferase activity coefficient (EALT-AC), aspartate aminotransferase activity coefficient (EAST-AC) and urinary 4-pyridoxic acid (4-PA), were correlated with vitamin B6 intake. Students with adequate values of plasma PLP (>35 nmol/l), EALT-AC ( < 1.25), EAST-AC ( < 1.8) and urinary 4-PA (>3.0 micromol/d) had median intakes of 1.08 and 1.01 mg/d, respectively, for boys and girls. This study suggests that vitamin B6 requirements for boys and girls aged 16-18 years were approximately 1.1 and 1.0 mg/d, respectively.

    This observer-blind study (clinicaltrials.gov NCT01462357) compared the immunogenicity and safety of 2 doses of the HPV-16/18 AS04-adjuvanted vaccine (HPV-16/18(2D)) vs. 2 or 3 doses of the HPV-6/11/16/18 vaccine (HPV-6/11/16/18(2D) and HPV-6/11/16/18(3D)) in healthy girls aged 9-14 y. Girls were randomized (1:1:1) to receive HPV-16/18(2D) at months (M) 0,6 (N = 359), HPV-6/11/16/18(2D) at M0,6 (N = 358) or HPV-6/11/16/18(3D) at M0,2,6 (N = 358). The primary objective was non-inferiority/superiority of HPV-16/18 antibodies by ELISA for HPV-16/18(2D) vs. HPV-6/11/16/18(2D) at M7 in the according-to-protocol immunogenicity cohort (ATP-I) and total vaccinated cohort, respectively. Secondary objectives included non-inferiority/superiority of HPV-16/18(2D) vs. HPV-6/11/16/18(3D) at M7, non-inferiority/superiority at M12, HPV-16/18 neutralizing antibodies, frequencies of T-cells/B-cells, reactogenicity and safety. Antibody responses at M7 for HPV-16/18(2D) were superior to those for HPV-6/11/16/18(2D) and HPV-6/11/16/18(3D) (lower limit of 95% confidence interval for geometric mean titer ratio (GMR) was >1): HPV-16/18(2D)/HPV-6/11/16/18(2D) GMRs were 1.69 [1.49-1.91] for anti-HPV-16 and 4.52 [3.97-5.13] for anti-HPV-18; HPV-16/18(2D)/HPV-6/11/16/18(3D) GMRs were 1.72 [1.54-1.93] for anti-HPV-16 and 3.22 [2.82-3.68] for anti-HPV-18; p = 0.0001 for all comparisons. Non-inferiority/superiority was also demonstrated at M12. Among initially seronegative girls in the ATP-I, neutralizing antibody titers were at least 1.8-fold higher for HPV-16/18(2D) vs. HPV-6/11/16/18(2D) and HPV-6/11/16/18(3D) at M7 and M12. Frequencies of HPV-16/18-specific T-cells and B-cells were in similar ranges between groups. Reactogenicity and safety were in line with the known profile of each vaccine. In conclusion, superior HPV-16/18 antibody responses were elicited by 2 doses of the HPV-16/18 AS04-adjuvanted vaccine compared with 2 or 3 doses of the HPV-6/11/16/18 vaccine in girls (9-14 years).

    Investigation of the prevalence and risk factors of human papillomavirus (HPV) infection is the basis for developing prophylactic strategies against cervical cancer, especially for young women. This study aimed to assess the prevalence and risk factors of HPV infection among a cohort of sexually active young French women eligible for catch-up vaccination. Between 1997 and 2007, 2163 women aged 15-23 years attending consultations at the department of gynecology in the Hospital of Besançon (France) were screened for high risk HPV (HR HPV) infection. Risk factors were investigated through a questionnaire sent to all participants in 2010. HPV DNA was detected by HC2 and Probe Set assays. The overall prevalence for HR HPV and HPV16, 18 and/or HPV45 was 44.6% (95% CI, 42.5-46.7%) and 19% (95% CI, 17.3-20.7%), respectively. The response rate to the questionnaire was 22.6%. The prevalence of independent risk factors (age older than 19, smoking, and oral contraception) for HPV 16/18/45 infection in this population was less than 20%. Based on this study, HPV vaccination should be offered not only to teenage girls, but also to young women, regardless of their sexual activity.

    Immunogenicity and safety of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine were evaluated in healthy Chinese females aged 9-45 years in 2 phase IIIB, randomized, controlled trials. Girls aged 9-17 years (ClinicalTrials.gov, NCT00996125) received vaccine (n = 374) or control (n = 376) and women aged 26-45 years (NCT01277042) received vaccine (n = 606) or control (n = 606) at months 0, 1, and 6. The primary objective was to show non-inferiority of anti-HPV-16 and -18 immune responses in initially seronegative subjects at month 7, compared with Chinese women aged 18-25 years enrolled in a separate phase II/III trial (NCT00779766). Secondary objectives were to describe the anti-HPV-16 and -18 immune response, reactogenicity and safety. At month 7, immune responses were non-inferior for girls (9-17 years) vs. young women (18-25 years): the upper limit of the 95% confidence interval (CI) for the geometric mean titer (GMT) ratio (women/girls) was below the limit of 2 for both anti-HPV-16 (0.37 [95% CI: 0.32, 0.43]) and anti-HPV-18 (0.42 [0.36, 0.49]). Immune responses at month 7 were also non-inferior for 26-45 year-old women vs. 18-25 year-old women: the upper limit of the 95% CI for the difference in seroconversion (18-25 minus 26-45) was below the limit of 5% for both anti-HPV-16 (0.00% [-1.53, 1.10]) and anti-HPV-18 (0.21% [-1.36, 1.68]). GMTs were 2- to 3-fold higher in girls (9-17 years) as compared with young women (18-25 years). The HPV-16/18 AS04-adjuvanted vaccine had an acceptable safety profile when administered to healthy Chinese females aged 9-45 years. PMID:25424785

    Background. This randomized, open trial compared regimens including 2 doses (2D) of human papillomavirus (HPV) 16/18 AS04-adjuvanted vaccine in girls aged 9–14 years with one including 3 doses (3D) in women aged 15–25 years. Methods. Girls aged 9–14 years were randomized to receive 2D at months 0 and 6 (M0,6; (n = 550) or months 0 and 12 (M0,12; n = 415), and women aged 15–25 years received 3D at months 0, 1, and 6 (n = 482). End points included noninferiority of HPV-16/18 antibodies by enzyme-linked immunosorbent assay for 2D (M0,6) versus 3D (primary), 2D (M0,12) versus 3D, and 2D (M0,6) versus 2D (M0,12); neutralizing antibodies; cell-mediated immunity; reactogenicity; and safety. Limits of noninferiority were predefined as <5% difference in seroconversion rate and <2-fold difference in geometric mean antibody titer ratio. Results. One month after the last dose, both 2D regimens in girls aged 9–14 years were noninferior to 3D in women aged 15–25 years and 2D (M0,12) was noninferior to 2D (M0,6). Geometric mean antibody titer ratios (3D/2D) for HPV-16 and HPV-18 were 1.09 (95% confidence interval, .97–1.22) and 0.85 (.76–.95) for 2D (M0,6) versus 3D and 0.89 (.79–1.01) and 0.75 (.67–.85) for 2D (M0,12) versus 3D. The safety profile was clinically acceptable in all groups. Conclusions. The 2D regimens for the HPV-16/18 AS04-adjuvanted vaccine in girls aged 9–14 years (M0,6 or M0,12) elicited HPV-16/18 immune responses that were noninferior to 3D in women aged 15–25 years.

    The comparative evaluation of the reactogenic and immunogenic properties of vaccine "Euvax B" in adolescents aged 16-18 years was carried out in factory housing estate Lvovsky, the Podolsk district, the Moscow region, and in the Yamalo-Nenets Autonomous District (AD): in towns Salekhard, Noyabrsk, Muravlenko, in housing estate Tarko-Sale. The evaluation demonstrated that the use of this vaccine in a dose of 20 mg/ml produced no postvaccinal complications and the frequency of postvaccinal reactions was insignificant. Postvaccinal anti-HBs were detected, on the average, in protective concentrations in 98.4 +/- 1.8% of the vaccines (99.0 +/- 1.9% in the Moscow region, 97.7 +/- 3.2% in the Yamalo-Nenets AD). In most of the vaccinated adolescents high concentrations of postvacinal anti-HBs were detected: in 51.4 +/- 9.7% of the vaccinees in the Moscow region and in 89.7 +/- 6.4% in the Yamalo-Nenets AD they exceeded 1,000 I.U./lit. The conclusion was made that in the territories located in subarctic latitudes vaccinal prophylaxis against hepatitis B was safe and highly effective and have no limitations connected with the conditions of the Far North.

    We previously reported higher anti-HPV-16 and -18 immune responses induced by HPV-16/18 vaccine compared with HPV-6/11/16/18 vaccine at Month 7 (one month after completion of full vaccination series) in women aged 18-45 y in an observer-blind study NCT00423046; the differences of immune response magnitudes were maintained up to Month 24. Here we report follow-up data through Month 48. At Month 48, in according-to-protocol cohort for immunogenicity (seronegative and DNA-negative for HPV type analyzed at baseline), geometric mean titers of serum neutralizing antibodies were 2.0- to 5.2-fold higher (HPV-16) and 8.6- to 12.8-fold higher (HPV-18) in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. The majority of women in both vaccine groups remained seropositive for HPV-16. The same trend was observed for HPV-18 in HPV-16/18 vaccine group; however, seropositivity rates in HPV-6/11/16/18 vaccine group decreased considerably, particularly in the older age groups. In the total vaccinated cohort (regardless of baseline serological and HPV-DNA status), anti-HPV-16 and -18 neutralizing antibody levels induced by HPV-16/18 vaccine were higher than those induced by HPV-6/11/16/18 vaccine. CD4+ T-cell response for HPV-16 and HPV-18 was higher in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. Memory B-cell responses appeared similar between vaccine groups. Both vaccines were generally well tolerated. Overall, the higher immune response observed with the HPV-16/18 vaccine was maintained up to Month 48. A head-to-head study incorporating clinical endpoints would be required to confirm whether the observed differences in immune response between the vaccines influence the duration of protection they provided.

    The observer-blind, randomized, age-stratified, head-to-head study (NCT00423046) comparing immunogenicity and safety of HPV-16/18 and HPV-6/11/16/18 vaccines in healthy women aged 18-45 y was completed. Five y after vaccination, in subjects from the Month 60 according-to-protocol cohort (seronegative and DNA negative for HPV type analyzed at baseline), serum neutralizing antibody (nAb) responses induced by HPV-16/18 vaccine remained 7.8-fold (18-26-y stratum), 5.6-fold (27-35-y stratum) and 2.3-fold (36-45-y stratum) higher than those induced by HPV-6/11/16/18 vaccine for HPV-16. For HPV-18, the fold differences were 12.1, 13.0 and 7.8, respectively. At Month 60, all (100%) subjects in HPV-16/18 vaccine group and the majority (95.7%-97.5%) in HPV-6/11/16/18 vaccine group were seropositive for HPV-16. For HPV-18, the majority (98.1%-100%) of subjects in HPV-16/18 vaccine group were seropositive; however, seropositivity rates in HPV-6/11/16/18 vaccine group decreased considerably (61.1%-76.9%) across the 3 age strata. In the total vaccinated cohort (received ≥1 dose regardless of baseline HPV serostatus and DNA status), geometric mean titers for anti-HPV-16 and anti-HPV-18 nAb were higher in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. Based on the 5-y data, piece-wise and modified power-law models predicted a longer durability of nAb response for HPV-16/18 vaccine compared to HPV-6/11/16/18 vaccine. Beyond the differences apparent between the vaccines in terms of immunogenicity and modeled persistence of antibody responses, comparative studies including clinical endpoints would be needed to determine whether differences exist in duration of vaccine-induced protection.

    The observer-blind, randomized, age-stratified, head-to-head study (NCT00423046) comparing immunogenicity and safety of HPV-16/18 and HPV-6/11/16/18 vaccines in healthy women aged 18-45 y was completed.

    In this observer-blind study (NCT00423046), women (N=1,106), stratified by age (18-26, 27-35, 36-45 y), were randomized (1:1) to receive the HPV-16/18 vaccine (Cervarix®, GlaxoSmithKline Biologicals, Months 0, 1, 6) or the HPV-6/11/16/18 vaccine (Gardasil® Merck & Co., Inc., Months 0, 2, 6). Month 7 results were previously reported; we now report Month 24 results. In the according-to-protocol cohort for immunogenicity (seronegative and DNA-negative at baseline for HPV type analyzed), seropositivity rates of neutralizing antibodies (nAbs) [pseudovirion-based neutralization assay] were, across all age strata, 100% (HPV-16/18 vaccine) and 97.5-100% (HPV-6/11/16/18 vaccine) for HPV-16, and 99.0-100% (HPV-16/18 vaccine) and 72.3-84.4% (HPV-6/11/16/18 vaccine) for HPV-18. Corresponding geometric mean titers (GMTs) were 2.4-5.8-fold higher for HPV-16 and 7.7-9.4-fold higher for HPV-18 with the HPV-16/18 vaccine versus the HPV-6/11/16/18 vaccine; HPV-16 and HPV-18 GMTs were significantly higher with the HPV-16/18 vaccine than the HPV-6/11/16/18 vaccine (p< 0.0001) in the total vaccinated cohort (received ≥1 vaccine dose, irrespective of baseline sero/DNA-status). Similar results were obtained using enzyme-linked immunosorbent assay (ELISA). Positivity rates and GMTs of antigen-specific IgG antibodies in cervicovaginal secretions (ELISA) were not significantly different between vaccines. At Month 24, CD4⁺ T-cell responses for HPV-16 and HPV-18 were higher with the HPV-16/18 vaccine; memory B-cell response was higher for HPV-18 with the HPV-16/18 vaccine and similar between vaccines for HPV-16. Both vaccines were generally well tolerated. Although an immunological correlate of protection has not been defined, differences in the magnitude of immune response between vaccines may represent determinants of duration of protection.

    We previously reported higher anti-HPV-16 and -18 immune responses induced by HPV-16/18 vaccine compared with HPV-6/11/16/18 vaccine at Month 7 (one month after completion of full vaccination series) in women aged 18–45 y in an observer-blind study NCT00423046; the differences of immune response magnitudes were maintained up to Month 24. Here we report follow-up data through Month 48. At Month 48, in according-to-protocol cohort for immunogenicity (seronegative and DNA-negative for HPV type analyzed at baseline), geometric mean titers of serum neutralizing antibodies were 2.0- to 5.2-fold higher (HPV-16) and 8.6- to 12.8-fold higher (HPV-18) in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. The majority of women in both vaccine groups remained seropositive for HPV-16. The same trend was observed for HPV-18 in HPV-16/18 vaccine group; however, seropositivity rates in HPV-6/11/16/18 vaccine group decreased considerably, particularly in the older age groups. In the total vaccinated cohort (regardless of baseline serological and HPV-DNA status), anti-HPV-16 and -18 neutralizing antibody levels induced by HPV-16/18 vaccine were higher than those induced by HPV-6/11/16/18 vaccine. CD4+ T-cell response for HPV-16 and HPV-18 was higher in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. Memory B-cell responses appeared similar between vaccine groups. Both vaccines were generally well tolerated. Overall, the higher immune response observed with the HPV-16/18 vaccine was maintained up to Month 48. A head-to-head study incorporating clinical endpoints would be required to confirm whether the observed differences in immune response between the vaccines influence the duration of protection they provided.

    Objective Evaluation of the long-term HPV-16/18 AS04-adjuvanted vaccine immunogenicity persistence in women. Design Multicentre, open-label, long-term follow-up (NCT00947115) of a primary phase–III study (NCT00196937). Setting Six centres in Germany and Poland. Population 488 healthy women (aged 15–55 years, age-stratified into groups: 15–25, 26–45, and 46–55 years) who received three vaccine doses in the primary study. Methods Immune responses were evaluated in serum and cervicovaginal secretion (CVS) samples 6 years after dose 1. Anti-HPV-16/18 geometric mean titres (GMTs) were measured by enzyme-linked immunosorbent assay (ELISA), and were used to fit the modified power-law and piecewise models, predicting long-term immunogenicity. Serious adverse events (SAEs) were recorded. Main outcome measures Anti-HPV-16/18 seropositivity rates and GMTs 6 years after dose 1. Results At 6 years after dose 1, all women were seropositive for anti-HPV–16 and ≥97% were seropositive for anti-HPV–18 antibodies. GMTs ranged from 277.7 to 1344.6 EU/ml, and from 97.6 to 438.2 EU/ml, for anti-HPV–16 and anti-HPV–18, respectively. In all age groups, GMTs were higher (anti-HPV–16, 9.3–45.1-fold; anti-HPV–18, 4.3–19.4-fold) than levels associated with natural infection (29.8 EU/ml). A strong correlation between serum and CVS anti-HPV-16/18 levels was observed, with correlation coefficients of 0.81–0.96 (anti-HPV–16) and 0.69–0.84 (anti-HPV–18). Exploratory modelling based on the 6–year data predicted vaccine-induced anti-HPV-16/18 levels above natural infection levels for at least 20 years, except for anti-HPV–18 in the older age group (piecewise model). One vaccine-related and two fatal SAEs were reported. Conclusions At 6 years after vaccination, immune responses induced by the HPV-16/18 AS04-adjuvanted vaccine were sustained in all age groups.

    Protection against oncogenic non-vaccine types (cross-protection) offered by human papillomavirus (HPV) vaccines may provide a significant medical benefit. Available clinical efficacy data suggest the two licensed vaccines (HPV-16/18 vaccine, GlaxoSmithKline Biologicals (GSK), and HPV-6/11/16/18 vaccine, Merck & Co., Inc.) differ in terms of protection against oncogenic non-vaccine HPV types -31/45. The immune responses induced by the two vaccines against these two non-vaccine HPV types (cross-reactivity) was compared in an observer-blind study up to Month 24 (18 mo post-vaccination), in women HPV DNA-negative and seronegative prior to vaccination for the HPV type analyzed (HPV-010 [NCT00423046]). Geometric mean antibody titers (GMTs) measured by pseudovirion-based neutralization assay (PBNA) and enzyme-linked immunosorbent assay (ELISA) were similar between vaccines for HPV-31/45. Seropositivity rates for HPV-31 were also similar between vaccines; however, there was a trend for higher seropositivity with the HPV-16/18 vaccine (13.0-16.7%) versus the HPV-6/11/16/18 vaccine (0.0-5.0%) for HPV-45 with PBNA, but not ELISA. HPV-31/45 cross-reactive memory B-cell responses were comparable between vaccines. Circulating antigen-specific CD4+ T-cell frequencies were higher for the HPV-16/18 vaccine than the HPV-6/11/16/18 vaccine (HPV-31 [geometric mean ratio [GMR] =2.0; p=0.0002] and HPV-45 [GMR=2.6; p=0.0092]), as were the proportion of T-cell responders (HPV-31, p=0.0009; HPV-45, p=0.0793). In conclusion, immune response to oncogenic non-vaccine HPV types -31/45 was generally similar for both vaccines with the exception of T-cell response which was higher with the HPV-16/18 vaccine. Considering the differences in cross-protective efficacy between the two vaccines, the results might provide insights into the underlying mechanism(s) of protection.

    The objective of this study was to determine the prevalence and some predictors for vaccine and non-vaccine types of HPV infections among bivalent HPV vaccinated and non-vaccinated young women in Uganda. This was a comparative cross sectional study 5.5 years after a bivalent HPV 16/18 vaccination (Cervarix®, GlaxoSmithKline, Belgium) pilot project in western Uganda. Cervical swabs were collected between July 2014-August 2014 and analyzed with a HPV genotyping test, CLART® HPV2 assay (Genomica, Madrid Spain) which is based on PCR followed by microarray for determination of genotype. Blood samples were also tested for HIV and syphilis infections as well as CD4 and CD8 lymphocyte levels. The age range of the participants was 15-24 years and mean age was 18.6(SD 1.4). Vaccine-type HPV-16/18 strains were significantly less prevalent among vaccinated women compared to non-vaccinated women (0.5% vs 5.6%, p 0.006, OR 95% CI 0.08(0.01-0.64). At type-specific level, significant difference was observed for HPV16 only. Other STIs (HIV/syphilis) were important risk factors for HPV infections including both vaccine types and non-vaccine types. In addition, for non-vaccine HPV types, living in an urban area, having a low BMI, low CD4 count and having had a high number of life time sexual partners were also significant risk factors. Our data concurs with the existing literature from other parts of the world regarding the effectiveness of bivalent HPV-16/18 vaccine in reducing the prevalence of HPV infections particularly vaccine HPV- 16/18 strains among vaccinated women. This study reinforces the recommendation to vaccinate young girls before sexual debut and integrate other STI particularly HIV and syphilis interventions into HPV vaccination packages.

    Human papillomavirus (HPV) infection can lead to significant disease in males, including anogenital warts, intraepithelial neoplasias, and several types of oral and anogenital cancers. The quadrivalent HPV (type 6/11/16/18) L1 virus-like particle (VLP) vaccine (qHPV vaccine; Gardasil) has recently been demonstrated to prevent persistent infection and associated disease related to vaccine HPV types in males. We report the overall immunogenicity results from a trial of the quadrivalent HPV vaccine in males. Overall, 3,463 heterosexual men and 602 men who had sex with men were enrolled into a randomized, placebo-controlled, double-blind safety, immunogenicity, and efficacy study. Serum samples were collected prior to vaccination at day 1 and at months 7, 24, and 36 postvaccination. Immunogenicity was evaluated with a multiplex, competitive Luminex immunoassay. Almost all subjects (97.4 to 99.2%) seroconverted for vaccine HPV types by month 7. At month 36, 88.9%, 94.0%, 97.9%, and 57.0% of subjects were still seropositive for HPV-6, -11, -16, and -18, respectively. For all vaccine HPV types, black subjects had significantly higher antibody titers at month 7 than did both Caucasian and Asian subjects. An anamnestic antibody response was seen in men seropositive before vaccination. The vaccine was highly immunogenic in males 16 to 23 years of age; responses were comparable to those observed in women. Furthermore, the immune responses were consistent with the established efficacy of the vaccine in the prevention of incident and persistent HPV infection, anogenital warts, and anal intraepithelial neoplasia.

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

    This randomized, partially-blind study (ClinicalTrials.gov registration number NCT00541970) evaluated the immunogenicity and safety of 2-dose (2D) schedules of the HPV-16/18 AS04-adjuvanted vaccine. Results to month (M) 24 have been reported previously and we now report data to M48 focusing on the licensed vaccine formulation (20 μg each of HPV-16 and -18 antigens) administered at M0,6 compared with the standard 3-dose (3D) schedule (M0,1,6). Healthy females (age stratified: 9–14, 15–19, 20–25 years) were randomized to receive 2D at M0,6 (n = 240) or 3D at M0,1,6 (n = 239). In the according-to-protocol immunogenicity cohort, all initially seronegative subjects seroconverted for HPV-16 and -18 antibodies and remained seropositive up to M48. For both HPV-16 and -18, geometric mean antibody titer (GMT) ratios (3D schedule in women aged 15–25 years divided by 2D schedule in girls aged 9–14 years) at M36 and M48 were close to 1, as they were at M7 when non-inferiority was demonstrated. The kinetics of HPV-16, -18, -31, and -45 antibody responses were similar for both groups and HPV-16 and -18 GMTs were substantially higher than natural infection titers. The vaccine had a clinically acceptable safety profile in both groups. In summary, antibody responses to a 2D M0,6 schedule of the licensed vaccine formulation in girls aged 9–14 years appeared comparable to the standard 3D schedule in women aged 15–25 years up to 4 years after first vaccination. A 2D schedule could facilitate implementation of HPV vaccination programs and improve vaccine coverage and series completion rates. PMID:24576907

    Investigations on caries profile and state of teeth treatment were made on 3752 high school pupils of 16-18 years, namely, rural and urban Black, Indian, Colored (Eur-African-Malay) and White pupils. Rural Blacks had a low mean DMFT of about 2, and a caries-free prevalence of 52%. Of the few with affected teeth, 10% were extracted, none filled, and 90% decayed; i.e. restorative dental attention was virtually nil. Among English and Afrikaans pupils attending Government Schools, mean DMFT was about 10, and caries-free prevalence negligible. Of affected teeth, 13% were extracted, 59% filled and 28% decayed. The situations regarding the urban Black, Indian and Colored groups were intermediate. The Jewish pupils, well-circumstanced and attending private school, had a mean DMFT of 6.5, moreover 6% were caries-free. Of affected teeth, 1% had been extracted; 93% were filled, and only 6% remained decayed. Since it transpired that the diets of the three White subgroups, cariogenically, were much the same, the advantageous position of the Jewish pupils was judged to be due primarily to their excellent oral hygiene motivation, particularly their demonstrably regular visits to dentists.

    Purpose To summarise post-licensure safety surveillance over more than 4 years of routine use of the human papillomavirus-16/18-AS04-adjuvanted vaccine (HPV-16/18 vaccine: Cervarix®, GlaxoSmithKline, Belgium). Methods We describe global post-licensure passive surveillance data based on routine pharmacovigilance from 18 May 2007 until 17 November 2011 and enhanced surveillance implemented during the 2-year national immunisation programme in the UK (school years 2008–2010). Results Spontaneous reports from countries worldwide showed a similar pattern for the most frequently reported adverse events after HPV-16/18 vaccination. No patterns or trends were observed for potential immune-mediated diseases after vaccination. Observed incidences of Bell's palsy and confirmed Guillain–Barré syndrome were within the expected range in the general population. Outcomes of pregnancy in women who were inadvertently exposed to HPV-16/18 vaccine during pregnancy, were in line with published reports for similar populations. Enhanced surveillance of adverse events in the UK triggered a review of cases of anaphylaxis, angioedema and syncope reports, leading to an update to the prescribing information. Conclusion Collaborative partnerships between industry and national regulatory agencies facilitated rapid notification and transfer of safety information, allowing for rapid responses in the event of a safety signal of adverse event of concern. More than 4 years of post-licensure experience may provide confidence to providers and the public about the safety profile of HPV-16/18 vaccine in routine use. The safety profile appears to be consistent with pre-licensure data reporting that HPV-16/18 vaccine has an acceptable benefit–risk profile in adolescent girls and women. PMID:24644078

    HPV-023 (NCT00518336; ClinicalTrial.gov) is a long-term follow-up of an initial double-blind, randomized (1:1), placebo-controlled study (HPV-001, NCT00689741) evaluating the efficacy against human papillomavirus (HPV)-16/18 infection and associated cyto-histopathological abnormalities, persistence of immunogenicity, and safety of the HPV-16/18 AS04-adjuvanted vaccine. Among the women, aged 15-25 years, enrolled in HPV-001 and who participated in the follow-up study HPV-007 (NCT00120848), a subset of 437 women from five Brazilian centers participated in this 36-month long-term follow-up (HPV-023) for a total of 113 months (9.4 years). During HPV-023, anti-HPV-16/18 antibodies were measured annually by enzyme-linked immunosorbent assay (ELISA) and pseudovirion-based neutralisation assay (PBNA). Cervical samples were tested for HPV DNA every 6 months, and cyto-pathological examinations were performed annually. During HPV-023, no new HPV-16/18-associated infections and cyto-histopathological abnormalities occurred in the vaccine group. Vaccine efficacy (VE) against HPV-16/18 incident infection was 100% (95%CI: 66.1, 100). Over the 113 months (9.4 years), VE was 95.6% (86.2, 99.1; 3/50 cases in vaccine and placebo groups, respectively) against incident infection, 100% (84·1, 100; 0/21) against 6-month persistent infection (PI); 100% (61·4, 100; 0/10) against 12-month PI; 97·1% (82.5, 99.9; 1/30) against ≥ ASC-US; 95·0% (68.0, 99.9; 1/18) against ≥ LSIL; 100% (45.2, 100; 0/8) against CIN1+; and 100% (-128.1, 100; 0/3) against CIN2+ associated with HPV-16/18. All vaccinees remained seropositive to HPV-16/18, with antibody titers remaining several folds above natural infection levels, as measured by ELISA and PBNA. There were no safety concerns. To date, these data represent the longest follow-up reported for a licensed HPV vaccine. PMID:25424918

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

    In this observer-blind study (NCT00423046), women (N = 1,106), stratified by age (18–26, 27–35, 36–45 y), were randomized (1:1) to receive the HPV-16/18 vaccine (Cervarix®, GlaxoSmithKline Biologicals, Months 0, 1, 6) or the HPV-6/11/16/18 vaccine (Gardasil® Merck and Co., Inc., Months 0, 2, 6). Month 7 results were previously reported; we now report Month 24 results. In the according-to-protocol cohort for immunogenicity (seronegative and DNA-negative at baseline for HPV type analyzed), seropositivity rates of neutralizing antibodies (nAbs) [pseudovirion-based neutralization assay] were, across all age strata, 100% (HPV-16/18 vaccine) and 97.5–100% (HPV-6/11/16/18 vaccine) for HPV-16, and 99.0–100% (HPV-16/18 vaccine) and 72.3–84.4% (HPV-6/11/16/18 vaccine) for HPV-18. Corresponding geometric mean titers (GMTs) were 2.4–5.8-fold higher for HPV-16 and 7.7–9.4-fold higher for HPV-18 with the HPV-16/18 vaccine vs. the HPV-6/11/16/18 vaccine; HPV-16 and HPV-18 GMTs were significantly higher with the HPV-16/18 vaccine than the HPV-6/11/16/18 vaccine (p < 0.0001) in the total vaccinated cohort (received ≥1 vaccine dose, irrespective of baseline sero/DNA-status). Similar results were obtained using enzyme-linked immunosorbent assay (ELISA ). Positivity rates and GMTs of antigen-specific IgG antibodies in cervicovaginal secretions (ELISA) were not significantly different between vaccines. At Month 24, CD4+ T-cell responses for HPV-16 and HPV-18 were higher with the HPV-16/18 vaccine; memory B-cell response was higher for HPV-18 with the HPV-16/18 vaccine and similar between vaccines for HPV-16. Both vaccines were generally well tolerated. Although an immunological correlate of protection has not been defined, differences in the magnitude of immune response between vaccines may represent determinants of duration of protection.

    Background A community-based randomized trial was conducted in Costa Rica to evaluate the HPV-16/18 AS04-adjuvanted vaccine (NCT00128661). The primary objective was to evaluate efficacy of the vaccine to prevent cervical intraepithelial neoplasia 2 or more severe disease (CIN2+) associated with incident HPV-16/18 cervical infections. Secondary objectives were to evaluate efficacy against CIN2+ associated with incident cervical infection by any oncogenic HPVs and to evaluate duration of protection against incident cervical infection with HPV-16/18. Vaccine safety and immunogenicity over the 4-year follow-up were also evaluated. Methods We randomized (3,727 HPV arm; 3,739 Control arm), vaccinated (HPV-16/18 or Hepatitis A) and followed (median 53.8 months) 7,466 healthy women aged 18-25 years. 5,312 women (2,635 HPV arm; 2,677 Control arm) were included in the according to protocol analysis for efficacy. The full cohort was evaluated for safety. Immunogenicity was considered on a subset of 354 (HPV-16) and 379 (HPV-18) women. HPV type was assessed by PCR on cytology specimens. Immunogenicity was assessed using ELISA and inhibition enzyme immunoassays. Disease outcomes were histologically confirmed. Vaccine efficacy and 95% confidence intervals (95%CI) were computed. Results Vaccine efficacy was 89.8% (95% CI: 39.5 - 99.5; N=11 events total) against HPV-16/18 associated CIN2+, 59.9% (95% CI: 20.7 - 80.8; N=39 events total) against CIN2+ associated with non-HPV-16/18 oncogenic HPVs and 61.4% (95% CI: 29.5-79.8; N=51 events total) against CIN2+ irrespective of HPV type. The vaccine had an acceptable safety profile and induced robust and long-lasting antibody responses. Conclusions Our findings confirm the high efficacy and immunogenicity of the HPV-16/18 vaccine against incident HPV infections and cervical disease associated with HPV-16/18 and other oncogenic HPV types. These results will serve as a benchmark to which we can compare future findings from ongoing extended

    In this randomized, partially-blind study (clinicaltrials.gov; NCT00541970), the licensed formulation of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine (20 μg each of HPV-16/18 antigens) was found highly immunogenic up to 4 y after first vaccination, whether administered as a 2-dose (2D) schedule in girls 9–14 y or 3-dose (3D) schedule in women 15–25 y. This end-of-study analysis extends immunogenicity and safety data until Month (M) 60, and presents antibody persistence predictions estimated by piecewise and modified power law models. Healthy females (age stratified: 9–14, 15–19, 20–25 y) were randomized to receive 2D at M0,6 (N = 240 ) or 3D at M0,1,6 (N = 239). Here, results are reported for girls 9–14 y (2D) and women 15–25 y (3D). Seropositivity rates, geometric mean titers (by enzyme-linked immunosorbent assay) and geometric mean titer ratios (GMRs; 3D/2D; post-hoc exploratory analysis) were calculated. All subjects seronegative pre-vaccination in the according-to-protocol immunogenicity cohort were seropositive for anti-HPV-16 and −18 at M60. Antibody responses elicited by the 2D and 3D schedules were comparable at M60, with GMRs close to 1 (anti-HPV-16: 1.13 [95% confidence interval: 0.82–1.54]; anti-HPV-18: 1.06 [0.74–1.51]). Statistical modeling predicted that in 95% of subjects, antibodies induced by 2D and 3D schedules could persist above natural infection levels for ≥ 21 y post-vaccination. The vaccine had a clinically acceptable safety profile in both groups. In conclusion, a 2D M0,6 schedule of the HPV-16/18 AS04-adjuvanted vaccine was immunogenic for up to 5 y in 9–14 y-old girls. Statistical modeling predicted that 2D-induced antibodies could persist for longer than 20 y. PMID:26176261

    HPV-023 (NCT00518336; ClinicalTrial.gov) is a long-term follow-up of an initial double-blind, randomized (1:1), placebo-controlled study (HPV-001, NCT00689741) evaluating the efficacy against human papillomavirus (HPV)-16/18 infection and associated cyto-histopathological abnormalities, persistence of immunogenicity, and safety of the HPV-16/18 AS04-adjuvanted vaccine. Among the women, aged 15–25 years, enrolled in HPV-001 and who participated in the follow-up study HPV-007 (NCT00120848), a subset of 437 women from five Brazilian centers participated in this 36-month long-term follow-up (HPV-023) for a total of 113 months (9.4 years). During HPV-023, anti-HPV-16/18 antibodies were measured annually by enzyme-linked immunosorbent assay (ELISA) and pseudovirion-based neutralisation assay (PBNA). Cervical samples were tested for HPV DNA every 6 months, and cyto-pathological examinations were performed annually. During HPV-023, no new HPV-16/18-associated infections and cyto-histopathological abnormalities occurred in the vaccine group. Vaccine efficacy (VE) against HPV-16/18 incident infection was 100% (95%CI: 66.1, 100). Over the 113 months (9.4 years), VE was 95.6% (86.2, 99.1; 3/50 cases in vaccine and placebo groups, respectively) against incident infection, 100% (84·1, 100; 0/21) against 6-month persistent infection (PI); 100% (61·4, 100; 0/10) against 12-month PI; 97·1% (82.5, 99.9; 1/30) against ≥ ASC-US; 95·0% (68.0, 99.9; 1/18) against ≥ LSIL; 100% (45.2, 100; 0/8) against CIN1+; and 100% (–128.1, 100; 0/3) against CIN2+ associated with HPV-16/18. All vaccinees remained seropositive to HPV-16/18, with antibody titers remaining several folds above natural infection levels, as measured by ELISA and PBNA. There were no safety concerns. To date, these data represent the longest follow-up reported for a licensed HPV vaccine. PMID:25424918

    Target groups for human papillomavirus (HPV) vaccination are controversial. We evaluated vaccine efficacy (VE) against 1-year persistent infection, stratified by age and sexual behavior, among young women in Costa Rica. We randomized 7,466 healthy women 18 to 25 years of age to HPV16/18 or hepatitis A vaccine (follow-up, 50.4 months). According-to-protocol (ATP) cohorts included compliant HPV-negative women; intention-to-treat (ITT) included all randomized women. ATP VE was 90.9% (95% CI, 82.0-95.9) against HPV16/18 infections, 44.5% against HPV31/33/45 (95% CI, 17.5-63.1), and 12.4% (95% CI, -3.2 to 25.6) against any oncogenic infection. Overall ITT VE against HPV16/18 infections was 49.0%, but ATP and ITT VE almost reached 100% in year 4 of follow-up. ATP efficacy against HPV16/18 was similar by age, but ITT VE was greatest among youngest women (68.9% among those 18-19 years of age; 21.8% among those 24-25 years of age) and 79.8% among virgins. Among previously unexposed women, vaccination is highly efficacious against HPV16/18 and partially against HPV31/33/45. Vaccination is most effective in women and girls before they initiate sexual activity, with programmatic and individual decision implications.

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

    Background Anal cancer remains rare (incidence of ∼1.5 per 100,000 women annually) but rates are increasing in many countries. Human papillomavirus-16 (HPV16) infection causes most cases. We evaluated vaccine efficacy (VE) of an ASO4-adjuvanted HPV16/18 vaccine against anal HPV16/18 infection. Methods In a randomized double-blind controlled trial designed to evaluate VE against persistent cervical HPV16/18 infections and associated precancerous lesions in Costa Rica, 4210 healthy women underwent anal specimen collection (4224 of 5968= 70.8% of eligible women) at the final blinded study visit 4 years after vaccination to evaluate anal HPV16/18 VE. Cervical HPV16/18 VE among the same women at the same visit was calculated as a comparator. For this ancillary work, analyses were conducted in a restricted cohort of women both cervical HPV16/18 DNA negative and HPV 16/18 seronegative prior at enrollment (N=1989), and in the full cohort (all women with an anal specimen). Findings In the restricted cohort, VE against prevalent HPV16/18 anal infection measured one-time, four-years post-vaccination was 83.6% (95%CI 66.7% to 92.8%), which was comparable to cervical HPV16/18 VE (87.9%, 95%CI 77.4% to 94.0%). In the full cohort, HPV16/18 VE was statistically lower at the anus (62.0%, 95%CI 47.1% to 73.1%) compared to the cervix (76.4%, 95%CI 67.0% to 83.5%) (p for anatomic-site interaction =0.03). Significant and comparable VE estimates against a composite endpoint of HPV31/33/45 (i.e.: cross-protection) was observed at the anus and cervix. Interpretation The ASO4-adjuvanted vaccine affords strong protection against anal HPV, particularly among women more likely to be HPV naïve at vaccination. Funding. The Costa Rica HPV Vaccine Trial is sponsored and funded by the NCI (contract N01-CP-11005), with funding support from the National Institutes of Health Office of Research on Women's Health, and conducted with support from the Ministry of Health of Costa Rica.

    Background Reduction in the prevalence of vaccine type HPV infection in young women is an early indication of the impact of the HPV immunisation programme and a necessary outcome if the subsequent impact on cervical cancer is to be realised. Methods Residual vulva-vaginal swab (VVS) specimens from young women aged 16–24 years undergoing chlamydia screening in community sexual health services (formerly known as family planning clinics), general practice (GP), and youth clinics in 2010–2012 were submitted from 10 laboratories in seven regions around England. These specimens were linked to demographic and sexual behaviour data reported with the chlamydia test, anonymised, and tested for type-specific HPV DNA using a multiplex PCR and Luminex-based genotyping test. Estimated immunisation coverage was calculated and findings were compared to a baseline survey conducted prior to the introduction of HPV immunisation in 2008. Results A total of 4664 eligible specimens were collected and 4178 had a valid test result. The post-immunisation prevalence of HPV 16/18 infection was lowest in this youngest age group (16–18 years) and increased with age. This increase with age was a reversal of the pattern seen prior to immunisation and was inversely associated with estimates of age-specific immunisation coverage (65% for 16–18 year olds). The prevalence of HPV 16/18 infection in the post-immunisation survey was 6.5% amongst 16–18 year olds, compared to 19.1% in the similar survey conducted prior to the introduction of HPV immunisation. Conclusions These findings are the first indication that the national HPV immunisation programme is successfully preventing HPV 16/18 infection in sexually active young women in England. The reductions seen suggest, for the estimated coverage, high vaccine effectiveness and some herd-protection benefits. Continued surveillance is needed to determine the effects of immunisation on non-vaccine HPV types. PMID:24211166

    Background 

 Endemic malaria and helminth infections in sub-Saharan Africa can act as immunological modulators and impact responses to standard immunizations. We conducted a cohort study to measure the influence of malaria and helminth infections on the immunogenicity of the bivalent HPV-16/18 vaccine. Methods 

 We evaluated the association between malaria and helminth infections, and HPV-16/18 antibody responses among 298 Tanzanian females aged 10–25 years enrolled in a randomized controlled trial of the HPV-16/18 vaccine. Malaria parasitaemia was diagnosed by examination of blood smears, and helminth infections were diagnosed by examination of urine and stool samples, respectively. Geometric mean antibody titres (GMT) against HPV-16/18 antibodies were measured by enzyme-linked immunosorbent assay. Results 

 Parasitic infections were common; one-third (30.4%) of participants had a helminth infection and 10.2% had malaria parasitaemia. Overall, the vaccine induced high HPV-16/18 GMTs, and there was no evidence of a reduction in HPV-16 or HPV-18 GMT at Month 7 or Month 12 follow-up visits among participants with helminths or malaria. There was some evidence that participants with malaria had increased GMTs compared to those without malaria. Conclusions 

 The data show high HPV immunogenicity regardless of the presence of malaria and helminth infections. The mechanism and significance for the increase in GMT in those with malaria is unknown. PMID:24291193

    Background Human papillomavirus (HPV) types 16 and 18 cause invasive cervical cancer and most invasive anal cancers (IACs). Overall, IAC rates are highest among men who have sex with men (MSM), especially MSM with HIV infection. Testosterone is prescribed for men showing hypogonadism and HIV-related wasting. While there are direct and indirect physiological effects of testosterone in males, its role in anal HPV16/18 infections in men is unknown. Methods Free testosterone (FT) was measured in serum from 340 Multicenter AIDS Cohort Study (MACS) participants who were tested for anal HPV16/18-DNA approximately 36 months later. The effect of log10-transformed current FT level on anal HPV16/18 prevalence was modeled using Poisson regression with robust error variance. Multivariate models controlled for other HPV types, cumulative years of exogenous testosterone use, race, age, lifetime number of receptive anal intercourse partnerships, body mass index, tobacco smoking, HIV-infection and CD4+ T-cell counts among HIV-infected, and blood draw timing. Results Participants were, on average, 60 (+5.4) years of age, White (86%), and HIV-uninfected (56%); Twenty-four percent tested positive for anal HPV16 and/or 18-DNA (HPV16 prevalence=17.1%, HPV18=9.1%). In adjusted analysis, each half-log10 increase of FT was associated with a 1.9-fold (95% Confidence Interval: 1.11, 3.24) higher HPV16/18 prevalence. Additionally, other Group 1 high-risk HPVs were associated with a 1.56-fold (1.03, 2.37) higher HPV16/18 prevalence. Traditional risk factors for HPV16/18 infection (age, tobacco smoking; lifetime number of sexual partners, including the number of receptive anal intercourse partnerships within 24 months preceding HPV testing) were poorly correlated with one another and not statistically significantly associated with higher prevalence of HPV16/18 infection in unadjusted and adjusted analyses. Conclusions Higher free testosterone was associated with increased HPV16/18 prevalence

    Vaccination against oncogenic human papillomavirus (HPV) types is one key intervention for cervical cancer prevention. This follow-up study assessed the persistence of the systemic and mucosal immune responses together with the safety profile of the HPV-16/18 AS04-adjuvanted vaccine administered to young women aged 10-25 years. Serum and cervicovaginal secretion (CVS) samples were collected at prespecified time-points during the 48-month follow-up period. Anti-HPV-16/18 antibody levels in serum and CVS were measured by enzyme-linked immunosorbent assay (ELISA). At Month 48, all subjects remained seropositive for serum anti-HPV-16 and -18 antibodies. As previously observed, anti-HPV-16 and -18 antibodies levels (ELISA Units/mL) were higher in subjects vaccinated at the age of 10-14 years (2862.2 and 940.8) compared to subjects vaccinated at the age of 15-25 years (1186.2 and 469.8). Moreover, anti-HPV-16 and -18 antibodies in CVS were still detectable for subjects aged 15-25 years (84.1% and 69.7%, respectively). There was a strong correlation between serum and CVS anti-HPV-16 and -18 antibodies levels (correlation coefficients = 0.84 and 0.90 at Month 48, respectively) supporting the hypothesis of transudation or exudation of serum immunoglobulin G antibodies through the cervical epithelium. The HPV-16/18 AS04-adjuvanted vaccine had a clinically acceptable safety profile. In conclusion, this follow-up study shows that the HPV-16/18 AS04-adjuvanted vaccine administered to preteen/adolescents girls and young women induces long-term systemic and mucosal immune response and has a clinically acceptable safety profile up to 4 years after the first vaccine dose.

    In developing countries, risk of human papillomavirus (HPV) infection may be increased by the high prevalence of human immunodeficiency virus (HIV) infection. We evaluated the safety and immunogenicity of the HPV-16/18 AS04-adjuvanted vaccine in HIV-infected women in South Africa. Asymptomatic HIV-positive women aged 18-25 years (N=120) were stratified by CD4⁺ T-cell count and randomised (1:1) to receive HPV-16/18 vaccine (Cervarix®; GlaxoSmithKline Vaccines) or placebo (Al[OH]3) at 0, 1 and 6 months (double-blind). HIV-negative women (N=30) received HPV-16/18 vaccine (open label). Anti-HPV-16/18 antibody and CD4⁺ T-cell responses, CD4⁺ T-cell count, HIV viral load, HIV clinical stage and safety were evaluated for 12 months. The safety and reactogenicity profile of the HPV-16/18 vaccine was comparable in HIV-positive and HIV-negative women. Irrespective of baseline HPV status, all HIV-positive and HIV-negative women who received the HPV-16/18 vaccine were seropositive for both HPV-16 and HPV-18 after the second vaccine dose (month 2) and remained seropositive for both antigens at month 12. Anti-HPV-16/18 antibody titres at month 12 remained substantially above levels associated with natural infection. The HPV-16/18 vaccine induced sustained anti-HPV-16/18 CD4⁺ T-cell responses in both HIV-positive and HIV-negative women. No impact of baseline CD4⁺ T-cell count or HIV viral load was observed on the magnitude of the immune response in HIV-positive women. In HIV-positive women, CD4⁺ T-cell count, HIV viral load and HIV clinical stage were unaffected by HPV-16/18 vaccine administration. In conclusion, the HPV-16/18 AS04-adjuvanted vaccine appears immunogenic and well-tolerated in women with HIV infection. Study ID: 107863/NCT00586339.

    This pooled analysis of data from four Phase III clinical trials was undertaken to assess the correlation between levels of anti-human papillomavirus (HPV)-16/18 antibodies in serum and cervicovaginal secretions (CVS) in girls and women vaccinated with the HPV-16/18 AS04-adjuvanted vaccine. Serum and CVS samples were collected from a subset of women aged 10-65 years (N=350) at pre-specified time-points from 7 to 36 months post-vaccination. Anti-HPV-16/18 antibody levels in serum and CVS were measured by enzyme-linked immunosorbent assay. Pearson correlation coefficients between serum and CVS antibody levels, standardized for total immunoglobulin G, were calculated at each time-point in women with detectable antibodies in both serum and CVS. All subjects had seroconverted at Month 7 and remained seropositive through Month 36 for both antigens. Geometric mean titers of anti-HPV-16/18 antibodies in serum were substantially higher at all time-points than those in a control group of women who had cleared a natural HPV infection in another trial. In women with detectable antibodies in both serum and CVS, good correlation was seen between HPV-16/18 antibody levels at all time-points (Pearson correlation coefficient: 0.84-0.92 for HPV-16 and 0.90-0.91 for HPV-18). The strong correlation between levels of HPV-16/18 antibodies in serum and CVS up to 36 months post-vaccination in girls and women vaccinated with the HPV-16/18 AS04-adjuvanted vaccine supports transudation of serum antibodies as the mechanism by which antibodies are introduced into CVS. These CVS antibodies may play a role in the protective efficacy of this vaccine. PMID:21157180

    Background Limited data suggest one or two doses of the HPV vaccines confer similar protection to the three-dose regimen. This study aimed to further evaluate the question of reduced-dose efficacy of the HPV-16/18 vaccine. Methods Summary-level data from the Costa Rica Vaccine Trial (CVT; NCT00128661) and the PApilloma TRIal against Cancer In young Adults (PATRICIA; NCT001226810), two phase III controlled, randomized, double-blind, clinical trials of the HPV-16/18 AS04-adjuvanted vaccine among young women, were combined in a post-hoc analysis (GSK e-track 202142) to investigate efficacy of fewer doses of the HPV-16/18 vaccine after four years of follow-up. Women were randomly assigned to receive three doses of the HPV-16/18 vaccine or to a control vaccine; yet some received fewer doses. After excluding women with <12-months follow-up or those HPV16/18 DNA-positive at enrollment (for the HPV16/18 endpoint), vaccine efficacy (VE) was calculated against one-time detection of incident HPV infections after three (n=11,110 HPV:11,217control), two (n=611:574), and one (N=292:251) dose(s). The main aim of the study was to ascertain HPV16/18 VE in both full and naïve cohorts, as well as to explore protection conferred against non-vaccine HPV types, by number of doses received. Findings VE against incident HPV16/18 infections for three doses was 77·0% (95%CI 74·7 to 79·1%), two doses was 76·0% (95%CI 62·0 to 85·3%), and one dose was 85·7% (95%CI 70·7 to 93·7%). VE against incident HPV31/33/45 infections for three doses was 59·7% (95%CI 56·0 to 63·0%), two doses was 37·7% (95%CI 12·4 to 55·9%), and one dose was 36·6% (95%CI −5·4 to 62·2%). However, two-dose women who received their second dose at six months, but not those receiving it at one month, had efficacy estimates against HPV 31/33/45 similar to the three-dose group (VE 68·1%, 95%CI 27·0 to 87·0%; CVT data only).

  19. Can human papillomavirus (HPV) genotyping classify non-16/18 high-risk HPV infection by risk stratification?

    PubMed Central

    2016-01-01

    Objective Infection with high-risk genotypes of human papillomavirus (HR-HPV) is the major cause of invasive cervical cancers. HPV-16 and HPV-18 are known to be responsible for two-thirds of all invasive cervical carcinomas, followed by HPV-45, -31, and -33. Current guidelines only differentiate HPV-16/18 (+) by recommending direct colposcopy for treatment. We tried to evaluate whether there are differences in risk among 12 non-16/18 HR-HPV genotypes in this study. Methods The pathology archive database records of 1,102 consecutive gynecologic patients, who had results for cervical cytology and histology and for HPV testing, as determined by HPV 9G DNA chip, were reviewed. Results Among the 1,102 patients, 346 were non-16/18 HR-HPV (+) and 231 were HPV-16/18 (+). We calculated the odds ratios for ≥cervical intraepithelial neoplasia 2 (CIN 2) of 14 groups of each HR-HPV genotype compared with a group of HR-HPV (–) patients. Based on the odds ratio of each genotype, we divided patients with non-16/18 HR-HPV genotypes (+) into two groups: HPV-31/33/35/45/52/58 (+) and HPV-39/51/56/59/66/68 (+). The age-adjusted odds ratios for ≥CIN 2 of the HPV-31/33/35/45/52/58 (+) and HPV-39/51/56/59/66/68 (+) groups compared with a HR-HPV (–) group were 11.9 (95% CI, 7.6 to 18.8; p<0.001) and 2.4 (95% CI, 1.4 to 4.3; p<0.001), respectively, while that of the HPV-16/18 (+) group was 18.1 (95% CI, 11.6 to 28.3; p=0.003). Conclusion The 12 non-16/18 HR-HPV genotypes can be further categorized (HPV-31/33/35/45/52/58 vs. HPV-39/51/56/59/66/68) by risk stratification. The HPV-31/33/35/45/52/58 genotypes might need more aggressive action. Large scale clinical trials or cohort studies are necessary to confirm our suggestion. PMID:27550402

    The Costa Rica Vaccine Trial (CVT) was a randomized clinical trial conducted between 2004 and 2010, which randomized 7466 women aged 18 to 25 to receive the bivalent HPV-16/18 vaccine or control Hepatitis-A vaccine. Participants were followed for 4 years with cross-over vaccination at the study end. In 2010 the long term follow-up (LTFU) study was initiated to evaluate the 10-year impact of HPV-16/18 vaccination, determinants of the immune response, and HPV natural history in a vaccinated population. Herein, the rationale, design and methods of the LTFU study are described, which actively follows CVT participants in the HPV-arm 6 additional years at biennial intervals (3 additional study visits for 10 years of total follow-up), or more often if clinically indicated. According to the initial commitment, women in the Hepatitis-A arm were offered HPV vaccination at cross-over; they were followed 2 additional years and exited from the study. 92% of eligible CVT women accepted participation in LTFU. To provide underlying rates of HPV acquisition and cervical disease among unvaccinated women to compare with the HPV-arm during LTFU, a new unvaccinated control group (UCG) of women who are beyond the age generally recommended for routine vaccination was enrolled, and will be followed by cervical cancer screening over 6 years. To form the UCG, 5000 women were selected from a local census, of whom 2836 women (61% of eligible women) agreed to participate. Over 90% of participants complied with an interview, blood and cervical specimen collection. Evaluation of comparability between the original (Hepatitis-A arm of CVT) and new (UCG) control groups showed that women's characteristics, as well as their predicted future risk for cervical HPV acquisition, were similar, thus validating use of the UCG. LTFU is poised to comprehensively address many important questions related to long-term effects of prophylactic HPV vaccines.

    The human papillomavirus type 16/18 (HPV-16/18) AS04-adjuvanted cervical cancer vaccine is licensed for females aged 10 years and above and is therefore likely to be coadministered with other licensed vaccines, such as hepatitis B. In this randomized, open-label study, we compared the immunogenicity of the hepatitis B vaccine administered alone (HepB group) or with the HPV-16/18 AS04-adjuvanted vaccine (HepB+HPV group) in healthy women aged 20 to 25 years (clinical trial NCT00637195). The hepatitis B vaccine was given at 0, 1, 2, and 12 months (an accelerated schedule which may be required by women at high risk), and the HPV-16/18 vaccine was given at 0, 1, and 6 months. One month after the third dose of hepatitis B vaccine, in the according-to-protocol cohort (n = 72 HepB+HPV; n = 76 HepB), hepatitis B seroprotection rates (titer of ≥10 mIU/ml) were 96.4% (95% confidence interval [CI], 87.5 to 99.6) and 96.9% (CI, 89.2 to 99.6) in the HepB+HPV and HepB groups, respectively, in women initially seronegative for anti-hepatitis B surface antigen (HBs) and anti-hepatitis B core antigen (HBc). Corresponding geometric mean titers of anti-HBs antibodies were 60.2 mIU/ml (CI, 40.0 to 90.5) and 71.3 mIU/ml (CI, 53.9 to 94.3). Anti-HBs antibody titers rose substantially after the fourth dose of hepatitis B vaccine. All women initially seronegative for anti-HPV-16 and anti-HPV-18 antibodies seroconverted after the second HPV-16/18 vaccine dose and remained seropositive up to 1 month after the third dose. Both vaccines were generally well tolerated, with no difference in reactogenicity between groups. In conclusion, coadministration of the HPV-16/18 AS04-adjuvanted vaccine did not affect the immunogenicity or safety of the hepatitis B vaccine administered in an accelerated schedule in young women.

    Background The cervical cancer screening program implemented in Hungary to date has not been successful. Along with screening, vaccination is an effective intervention to prevent cervical cancer. The aim of this study was to assess the cost-effectiveness of adding vaccination with the human papillomavirus 16/18 vaccine to the current cervical cancer screening program in Hungary. Methods We developed a cohort simulation state-transition Markov model to model the life course of 12-year-old girls. Eighty percent participation in the HPV vaccination program at 12 years of age was assumed. Transitional probabilities were estimated using data from the literature. Local data were used regarding screening participation rates, and the costs were estimated in US $. We applied the purchasing power parity exchange rate of 129 HUF/$ to the cost data. Only direct health care costs were considered. We used a 3.7% discount rate for both the cost and quality-adjusted life years (QALYs). The time horizon was 88 years. Results Inclusion of HPV vaccination at age 12 in the cervical cancer prevention program was predicted to be cost-effective. The incremental cost-effectiveness ratio (ICER) of adding HPV vaccination to the current national cancer screening program was estimated to be 27 588 $/QALY. The results were sensitive to the price of the vaccine, the discount rate, the screening participation rate and whether herd immunity was taken into account. Conclusions Our modeling analysis showed that the vaccination of 12-year-old adolescent girls against cervical cancer with the AS04-adjuvanted human papillomavirus 16/18 vaccine would be a cost-effective strategy to prevent cervical cancer in Hungary.

    Objectives The human papillomavirus (HPV) immunisation programme in England was introduced in 2008. Monitoring changes in type-specific HPV prevalence allows assessment of the population impact of this vaccination programme. Methods Residual vulva-vaginal swab specimens were collected from young sexually active women (aged 16–24 years) attending for chlamydia screening across England. Specimens were collected between 2010 and 2013 for type-specific HPV-DNA testing. HPV prevalence was compared to a similar survey conducted in 2008 prior to the introduction of HPV vaccination. Results A total of 7321 specimens collected in the postvaccination period, and 2354 specimens from the prevaccination period were included in this analysis. Among the individuals aged 16–18 years, with an estimated vaccination coverage of 67%, the prevalence of HPV16/18 infection decreased from 17.6% in 2008 to 6.1% in the postvaccination period. Within the postvaccination period, there was a trend towards lower HPV16/18 prevalence with higher vaccination coverage and increasing time since vaccine introduction from 8.5% in the period 2–3 years postvaccination to 4.0% in the period 4–5 years postvaccination. The prevalence of HPV31 reduced from 3.7% in the prevaccination period to 0.9% after vaccine introduction, although this no longer reached statistical significance after additional consideration of the uncertainty due to the assay change. Smaller reductions were seen in the individuals aged 19–21 years with lower estimated vaccination coverage, but there was no evidence of a reduction in the older unvaccinated women. Some overall increase in non-vaccine types was seen in the youngest age groups (ORs (95% CI); 1.3 (1.0 to 1.7) and 1.5 (1.1 to 2.0) for individuals aged 16–18 and 19–21 years, respectively, when adjusted for known population changes and the change in assay) although this should be interpreted with caution given the potential unmasking effect

    Background Prophylactic vaccination with a quadrivalent HPV (types 6, 11, 16, 18) vaccine (qHPV) has been shown to prevent infection with HPV 6/11/16/18 and associated disease in women and more recently, in men. Here we report on the safety and reactogenicity of the qHPV vaccine in males. A total of 4,065 healthy males aged 16–26 years were enrolled into a randomized, placebo-controlled, double-blind trial. Subjects were randomized 1:1 to receive qHPV vaccine or placebo at day 1, month 2 and month 6. Safety and tolerability were assessed via the collection of reported adverse experiences (AEs). All serious AEs (vaccine- or procedure-related or not) and all deaths occurring during the study were recorded. Safety analyses were conducted in all subjects who received at least one dose of vaccine or placebo. The proportion of subjects who reported at least one injection-site AE was higher in the qHPV vaccine group versus the placebo group (60.1% vs. 53.7%, respectively), however most of these AEs were mild/moderate in intensity. The incidence of at least one systemic AE was comparable between the vaccine and placebo groups (31.7% vs. 31.4%, respectively). There were no vaccine-related serious AEs or deaths. The occurrence of AEs did not increase with each successive injection, and among trial participants who were seropositive for at least one vaccine HPV type at enrollment, the profile of adverse events was similar to that of the entire study cohort. The qHPV vaccine was generally well tolerated in males aged 16–26 years and had a favorable safety profile. PMID:21712645

    Purpose The purpose of this study is to further evaluate the safety of the human papillomavirus (HPV)-16/18-AS04-adjuvanted vaccine (HPV-16/18-vaccine Cervarix®, GlaxoSmithKline, Belgium) through a pooled analysis of data from 42 completed/ongoing clinical studies. Methods Unsolicited adverse events (AEs) were reported for 30 days after each dose. Medically significant conditions, serious AEs (SAEs), potential immune-mediated diseases (pIMDs) and pregnancy outcomes were captured until study completion. Events leading to subject withdrawal were reviewed. Relative risks compared incidences of spontaneous abortion and pIMDs in controlled studies. Results Thirty one thousand one hundred seventy-three adolescent girls/women received HPV-16/18-vaccine alone (HPV group), 2166 received HPV-16/18-vaccine coadministered with another vaccine and 24 241 were controls. Mean follow-up was 39 months (range 0–113.3). Incidences of unsolicited AEs reported within 30 days after any dose were similar between HPV and Control groups (30.8%/29.7%). During the entire study period, reports of medically significant conditions (25.0%/28.3%) and SAEs (7.9%/9.3%) were also similarly distributed between groups. Deaths were rare: HPV (alone/coadministered) n = 25, controls n = 20 (n = 18 in blinded groups). pIMDs within 1 year were reported by 0.2% of HPV-16/18 vaccinees and controls. For each pIMD event category, no increased relative risks were reported for HPV-16/18 vaccinees versus controls. Coadministration did not change the overall safety profile. Pregnancy outcomes and withdrawal rates were similar between groups. Conclusions Analysis of safety data arising from 57 580 subjects and 96 704 HPV-16/18-vaccine doses shows that the incidences and distribution of AEs were similar among HPV-16/18-vaccine recipients and controls. No new safety signals were identified. The data confirm previous findings that HPV-16/18-vaccine has an acceptable benefit-risk profile in adolescent girls and

    The Demirjian methods to determine dental age are based on analysis of orthopantograms. The dental age estimation is based on establishing the tooth development stages. The purpose of this study was to assess the accuracy of estimation of dental age by Demirjian in the use of all of his four methods. 505 Czech healthy boys and girls aged 3 to 18 years were examined radiographically at the Department of Stomatology, Second Faculty of Medicine, Charles University in Prague. It was mentioned the factors of underlying diseases influence the accuracy of the dental age estimation. For statistical evaluation, descriptive statistics was used to compare deviations of the mean values of chronological and dental age in each age group. The resulting difference between dental age and chronological age is not significant in both genders only when using both Demirjian 7-teeth methods of 1973 and 1976. Therefore these may be most appropriately used for forensic age estimation. There are shown standard deviation differences in different countries. Demirjian's original 7-teeth method from 1973 and Demirjian's revised 4-teeth method from 1976 appear to be the best methods for calculating the dental age of healthy Czech children of both genders.

    The pattern of incidence rates according to age for many forms of cancer has been found to be in reasonable accord with the equation or some modification of it: It = btk, where It is the incidence rate at age t, and b and k are constants. An alternative equation postulates that the risk of cancer is determined not by the age of a person but by the length of time exposed to a carcinogenic agent: It = b(t-w)k, where t-w represents the "effective exposure" between first exposure and clinical evidence of cancer. Mesothelioma rates in asbestos insulation workers were strongly related to time from onset of exposure regardless of age at first exposure. However, the same pattern was not evident for lung cancer mortality in the same workers compared with blue collar worker controls from the American Cancer Society Cancer Prevention Study I. Lung cancer mortality by attained rates and by duration of smoking were shown for current smokers of cigarettes only for the Cancer Society study, classified by age at which they started smoking. Lung cancer results were also given for men who never smoked regularly.

    The literature suggests that one of the key determinants of success at rugby union international competitions is the anthropometric profile of players. The Irish Rugby Football Union (IRFU) long-term player development (LTPD) model is a framework designed to guide the development of the tactical, physical, and psychological domains of sporting participation. In Ireland, the Train-to-Train stage of the IRFU model is a critical stage, whereby the next developmental progression would include the transition of players into professional academies. To date, no previously published studies have examined the anthropometric profile of Irish Schools' rugby union players at the Train-to-Train stage of the IRFU model. The anthropometric profile of 136 male adolescent rugby union players at the Train-to-Train stage of the IRFU model was assessed using total-body dual-energy x-ray absorptiometry. Significant differences in height, body mass, body fat percentage, fat mass, lean mass, and fat-free mass were observed between players assigned to the forward and back units, and for specific position categorizations within each unit. Direct logistic regression revealed that body mass was a statistically significant (p < 0.01) predictor of unit position classification, with an odds ratio of 2.35, indicating that the players with a higher body mass were twice as likely to be classified as forwards. The results of this study indicate that at the Train-to-Train stage of the IRFU model, forward and back units have distinctly different anthropometric profiles. Furthermore, anthropometric differentiation also exists within specific position categorizations within each of these playing units. Thus, anthropometric profiling should be carried out on a systematic and periodic basis, because this will allow for the evaluation of the effectiveness of the implementation strategies of the IRFU model on a national basis.

  19. [The new legal marriage age: 21 years].

    PubMed

    Tallon, F

    1992-12-01

    In Rwanda, Presidential Decree No. 102/05 of March 13, 1992 executed Law No. 42/1988, which was not enforced after its passage in October 1988. Its principal provisions relate to civil marriage. Only monogamous civil marriage is recognized by law. Civil marriage is the voluntary union of a man and woman. A man and woman younger than 21 cannot marry except for grave reasons. Consanguineous marriages down to the seventh line of the family tree are prohibited. Other prohibited marriages include marriages between a person and his/her parents-in-law, an adoptive parent and the adopted child, an adoptive parent and descendants of the adopted child, the spouse of an adoptive parent and the adopted child, adopted children of the same adoptive parent, and an adopted child and a child of the adoptive parent. No one can remarry before annulment or dissolution of the preceding marriage. The wife cannot remarry before 300 days have passed since the end of the preceding marriage in case of pregnancy. At the end of the 300 days, she must have a medical certificate established by an ad hoc commission attesting that she is or is not pregnant. Before the wedding, the civil service officer posts at the civil state bureau information on future spouses and where the wedding will take place. The most important issue to emerge from this law is the legal marriage age being 21 rather than 18. The legislator set it at 21 as a means to realize objectives of the population policy. It favors a fertility slow-down. Some persons will say that this new law will have little effect on fertility. It is perhaps true since the last population census shows that the mean age at first union is almost 23 and civil marriage is only one of three existing forms of union.

    We report final event-driven analysis data on the immunogenicity and efficacy of the human papillomavirus 16 and 18 ((HPV-16/18) AS04-adjuvanted vaccine in young women aged 15 to 25 years from the PApilloma TRIal against Cancer In young Adults (PATRICIA). The total vaccinated cohort (TVC) included all randomized participants who received at least one vaccine dose (vaccine, n = 9,319; control, n = 9,325) at months 0, 1, and/or 6. The TVC-naive (vaccine, n = 5,822; control, n = 5,819) had no evidence of high-risk HPV infection at baseline, approximating adolescent girls targeted by most HPV vaccination programs. Mean follow-up was approximately 39 months after the first vaccine dose in each cohort. At baseline, 26% of women in the TVC had evidence of past and/or current HPV-16/18 infection. HPV-16 and HPV-18 antibody titers postvaccination tended to be higher among 15- to 17-year-olds than among 18- to 25-year-olds. In the TVC, vaccine efficacy (VE) against cervical intraepithelial neoplasia grade 1 or greater (CIN1+), CIN2+, and CIN3+ associated with HPV-16/18 was 55.5% (96.1% confidence interval [CI], 43.2, 65.3), 52.8% (37.5, 64.7), and 33.6% (−1.1, 56.9). VE against CIN1+, CIN2+, and CIN3+ irrespective of HPV DNA was 21.7% (10.7, 31.4), 30.4% (16.4, 42.1), and 33.4% (9.1, 51.5) and was consistently significant only in 15- to 17-year-old women (27.4% [10.8, 40.9], 41.8% [22.3, 56.7], and 55.8% [19.2, 76.9]). In the TVC-naive, VE against CIN1+, CIN2+, and CIN3+ associated with HPV-16/18 was 96.5% (89.0, 99.4), 98.4% (90.4, 100), and 100% (64.7, 100), and irrespective of HPV DNA it was 50.1% (35.9, 61.4), 70.2% (54.7, 80.9), and 87.0% (54.9, 97.7). VE against 12-month persistent infection with HPV-16/18 was 89.9% (84.0, 94.0), and that against HPV-31/33/45/51 was 49.0% (34.7, 60.3).

A retrospective case control study was conducted, including women aged 40 years and over (study group, n = 97) who delivered at 20 week's gestation or beyond and women aged 20-29 years (control group, n = 97). Results. The mean age of women in the study group was 41.2 ± 1.7 years versus 25.4 ± 2.3 years in the control group. Advanced maternal age was associated with a significantly higher rate of hypertension, diabetes mellitus, fetal complication, and 5-minute Apgar scores <7 (P < 0.05). Caeserean section rate, incidence of placental abruption, preterm delivery, and neonatal intensive care unit admission were more common in the older group, but the differences were not statistically significant. Conclusions. Advanced maternal age is related to maternal and neonatal complications.

    Exfoliated cervical cells from 321 Japanese women were examined for human papillomavirus (HPV) DNA types 6, 11, 16, 18, 31, 33 and 35 using polymerase chain reaction (PCR) and dot-blot hybridization methods. HPV DNA was present in 9.3% of patients with normal cervixes, 72.7% of patients with cervical intraepithelial neoplasia (CIN) and 77.8% of patients with invasive carcinoma. Younger patients (years) with normal cervixes had a 18.5% incidence of HPV DNA, whilst similar older patients (>/=50 years) had a 1.9% incidence, a significant difference (chi2= 6.478, P < 0.01). In the CIN I and II groups, an incidence of 11.1% of types 16 and 18 was found, while in the CIN III or invasive carcinoma group the incidence was 58.1%, again a significant difference (chi2 = 12.075, P < 0.01). Furthermore, persistence or progression of CIN showed a significant correlation with infections by types 16 and 33 (chi2= 4.904, P < 0.01). However, no significantly different incidence of HPV infection was found between the CIN and the invasive carcinoma groups. It is suggested that (a) younger patients with normal cervixes have a higher incidence of HPV infection than do older patients; (b) HPV types 16, 18 and 33 are important etiologic agents of CIN III and invasive carcinoma, as well as in the persistence and progression of CIN; (c) progression of CIN to invasive carcinoma may depend on factors other than HPV infection in the cervix.

    This report of health care spending in fiscal year 1977 reveals that of the $142.6 billion spent by the Nation for personal health care in fiscal year 1977, 29 percent was spent for those aged 65 or older, 59 percent for those aged 19-64, and 13 percent for those below age 19. The average health bill reached $1,745 for the aged, $661 for the intermediate age group, and $253 for the young. Public funds financed 67 percent of the health expenses of the aged, with Medicare and Medicaid together accounting for 61 percent. More than two-thirds of the health expenses of the young and 71 percent of the expenses of those aged 19-64 were paid by private sources. Third-party payments met 68 percent of the health expenditures of all those under age 65. PMID:107600

    The present study aimed to evaluate the association between the consumption of energy-dense foods at 2 years of age and the consumption of foods and diet quality at 4 years of age. The sample included 705 children evaluated at 2 and 4 years of age, as part of the population-based birth cohort Generation XXI (Porto, Portugal). Data on sociodemographic and lifestyle factors of both children and mothers were collected by face-to-face interviews. The weight and height of children were measured by trained professionals. Based on FFQ, four energy-dense food groups were defined: soft drinks; sweets; cakes; salty snacks. A healthy eating index was developed using the WHO dietary recommendations for children (2006) aged 4 years. The associations were evaluated through Poisson regression models. After adjustment for maternal age and education, child's carer, child's siblings and child's BMI, higher consumption of energy-dense foods at 2 years of age was found to be associated with higher consumption of the same foods 2 years later. An inverse association was found between the intake (≥ median) of soft drinks (incidence rate ratio (IRR) = 0.74, 95% CI 0.58, 0.95), salty snacks (IRR = 0.80, 95% CI 0.65, 1.00) and sweets (IRR = 0.73, 95% CI 0.58, 0.91) at 2 years of age and the consumption of fruit and vegetables at 4 years of age (≥ 5 times/d). Weekly and daily consumption of energy-dense foods at 2 years of age was associated with a lower healthy eating score at 4 years of age (IRR = 0.75, 95% CI 0.58, 0.96; IRR = 0.56, 95% CI 0.41, 0.77, respectively). The consumption of energy-dense foods at young ages is negatively associated with the diet quality of children a few years later.

    We hypothesized that placental villous branching that is measured by disk chorionic plate expansion and disk thickness is correlated with factors also involved in regulation of branching growth of other fetal viscera (e.g. lung, kidney) including neuronal dendrites, and thus may be associated with variation in childhood intelligence quotient (IQ). IQ at age 7 years was assessed using the Wechsler Intelligence Scale for Children. Placental measures [placental weight (g), thickness (mm), chorionic plate surface diameters (cm), area (cm2), shape, and cord length and cord eccentricity] were independent variables in regression analyses of age 7-year IQ in 12,926 singleton term live born infants with complete placental data. Analyses were stratified on gender with adjustment for socioeconomic status, race, parity, gestational age, exact age at testing and centered parental ages. After adjustment for covariates, placental measurements were independently associated with IQ at age 7 years but results varied by gender. Chorionic plate diameters were only associated with higher IQ in girls. Placental thickness was positively associated with higher IQ for boys and girls. We have previously shown that placental measures affect age 7-year body mass index and diastolic blood pressure. Here we demonstrate that specific measures, placental chorionic plate diameters in girls and disk thickness, independent of gender, are correlated with age 7-year IQ. Further exploration of the possible interaction of these factors on the placental villous arborization reflected by the chorionic plate expansion and placental thickness that correlate with age 7-year IQ, as well as other age 7 somatic features as previously addressed, is indicated.

    DNA-STR analysis is widely used in the forensic science field and obtaining results in shorter time is highly demanded. The developed forensic STR Kit, referred to as Expressmarker 16+10Y (EX16+10Y) and Expressmarker 16+18Y (EX16+18Y), could amplify the common autosomal and Y chromosome STR loci simultaneously. The kits are validated by a series of tests, including DNA mixtures, stutter ratios, PCR based studies, species specificities, inhibitors, sensitivity, sizing precision, reproducibility and parallel tests. The results demonstrated that EX16+10Y and EX16+18Y were useful tools for rapid criminal investigation. PMID:27243781

    This paper reports the results of a study of the persistence of individual differences in the phonological development of 10 normally developing children observed at age 1 year and again at age 3 years. Data were based on 1/2-hr audio and video recordings of weekly spontaneous mother-child interaction sessions in the home between 9 and 17 months and at 36 months. In addition, phonological and cognitive probes were administered at age 3. At age 1 the children were compared at four times selected on the basis of the number of different word types used in a session. Preferences for particular phonological categories (fricatives, liquids, final consonants) were found not to correspond to relative mastery of those categories at age 3. Based on both babble and words, high use of vocalizations containing true consonants was found to be predictive of greater phonological advance at age 3. Phonological errors of two kinds were distinguished for age 3: those resulting from difficulty with specific segments and those more typical of younger children, involving the rearrangement, assimilation, or deletion of segments or syllables (prosodic errors). The children differed in intelligibility and in specific segment substitutions and cluster reductions. They also differed in the proportion of prosodic errors made and in consistency in segmental errors. Lastly, aspects of cognitive or learning style as expressed in phonological organization were found to be recognizable at both age 1 and age 3.

    Anthropometric measurements of 1169 Saudi school boys between the ages of 6 and 14 years are reported. The boys were randomly selected from primary schools in the city of Riyadh, Saudi Arabia. Measurements of height, weight, grip strength, chest, triceps and subscapular skinfold thicknesses as well as biacromial, chest, bi-iliac, knee, and elbow breadths were taken. Saudi boys have slightly lower values for body weight and height than American boys (NCHS standards). Values of skinfold measurements increased with age up to age 11 where they plateaued and took then a sharp increase by age 14. Means of triceps and subscapular skinfolds of the Saudi boys are also lower than some standards from U.S.A. throughout age 13. At age 14, however, the Saudi boys have higher means than the U.S.A. boys.

    Leprosy is a chronic infectious disease caused by Mycobacterium leprae, representing a public health issue in some countries. Though more prevalent in adults, the detection of new cases in children under 15 years of age reveals an active circulation of bacillus, continued transmission and lack of disease control by the health system, as well as aiding in the monitoring of the endemic. Among patients under 15 years of age, the most affected age group is children between 10 and 14 years of age, although cases of patients of younger than 1 year of age have also been reported. Household contacts are the primary source of infection, given that caretakers, such as babysitters and others, must be considered in this scenario. Paucibacillary forms of the disease prevailed, especially borderline-tuberculoid leprosy, with a single lesion in exposed areas of the body representing the main clinical manifestation. Reactional states: Lepra reactions are rare, although some authors have reported high frequencies of this phenomenon, the most frequent of which is Type 1 Lepra Reaction. Peripheral nerve involvement has been described at alarming rates in some studies, which increases the chance of deformities, a serious problem, especially if one considers the age of these patients. The protective effect of BCG vaccination was found in some studies, but no consensus has been reached among different authors. Children must receive the same multidrug therapy regimen and the doses should, ideally, be calculated based on the child´s weight. Adverse reactions to this therapy are rare within this age group. This article aims to review epidemiological, clinical, and therapeutic aspects of leprosy in patients under 15 years of age. PMID:27192519

    Background Poor fear conditioning characterizes adult psychopathy and criminality, but it is not known whether it is related to aggressive/antisocial behavior in early childhood. Methods Using a differential, partial reinforcement conditioning paradigm, electrodermal activity was recorded from 200 male and female children at ages 3, 4, 5, 6, and 8 years. Antisocial/aggressive and hyperactive-inattentive measures were collected at age 8, while social adversity was assessed at age 3. Results Poor electrodermal fear conditioning from ages 3 to 8 years was associated with aggressive behavior at age 8 in both males and females. Conclusions Results indicate that the relationship between poor fear conditioning and aggression occurs early in childhood. Enhanced electrodermal fear conditioning may protect children against future aggressive/violent behavior. Abnormal amygdala functioning, as indirectly assessed by fear conditioning, may be one of the factors influencing the development of childhood aggression. PMID:19788551

    The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged <1 year; toddlers aged 1-2 years; preschoolers aged 3-4 years). Evidence from the review was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The new guidelines include a preamble to provide context, followed by the specific recommendations. The final guidelines benefitted from extensive on-line consultations with input from >900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged <1 year), toddlers (aged 1-2 years), and preschoolers (aged 3-4 years) spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

    Human papillomavirus (HPV) types 16, 18 and 33 were identified by means of the polymerase chain reaction using exfoliated cells from the uterine cervix in 361 patients. Of 261 patients without cervical lesions, 10(3.8%) patients had HPV DNA whereas 7(70.0%) of 10 patients with invasive cervical carcinomas had HPV DNA. The younger patients' group (29 year-old or less) without cervical lesions had a 6.5% HPV positive rate which was distinctly higher than the older patients' groups. No menopausal patient without cervical lesions had HPV DNA. In the cervical dysplasia group, the HPV DNA positive rate tended to be higher in the older patients. Type 16 was detected more often than types 18 or 33. However, the detectable incidence of type 16 in the follow up group was lower than in the cervical carcinoma groups. The younger patients without cervical lesions had a higher incidence of type 16 than the older patients. The younger patients with cervical neoplastic lesions had a lower incidence of type 16 than the older patients. These results suggest that type 16 has a higher frequency of cervical HPV infections than types 18 and 33. In addition, human papillomavirus is not the only causative factor in cervical carcinomas.

    We present simulations of marine radiocarbon reservoir ages using the ocean general circulation model LSG-HAMOCC2s, and evaluate the results with Marine13 raw data records. Our model considers various climatic background states. Radiocarbon cycle boundary conditions are atmospheric Δ14C values according to IntCal13, a recent atmospheric CO2 reconstruction, and spatially variable concentrations of dissolved inorganic carbon derived from marine carbon cycle simulations. Our model reasonably agrees with glacial marine Δ14C records but indicates reservoir ages varying with time, different to the invariant reservoir age corrections applied to the observations and to Marine13. Modelled global-mean reservoir ages are in the range 400-800 years compared to the invariant Marine13 value of 405 years. Self-consistent simulations involving the Cariaco Basin record (which is the most continuous marine record contributing to IntCal13 for periods prior to about 30 kyears) amplify the temporal reservoir age variability with global-mean values of about 350-850 years, and improve the agreement with Δ14C observations in some areas.

    Recurrence and survival pattern in breast cancer (bc) patients (pts) ≥ 70 years subcategorized according to subtype and age are still an area of uncertainty. Tumor characteristics, patient demographics, therapies applied, and recurrence pattern were compared between luminal A (LA), luminal B (LB), Her2/neu overexpressing (Her+) and triple-negative (TN) bc subtypes and the age subcategories 70-74, 75-79, ≥80 years. Based on univariate Cox-regression-analyses distant-disease-free-survival (DDFS) differed significantly for bc subtypes (p = 0.0002), notably for Her+ vs. LA (p = 0.0014), TN vs. LA (p < 0.001), and TN vs. LB (p = 0.0086).

    The AIAA/NASA Symposium on Space Tracking and Data Systems, held in Pentagon City, Virginia, on June 16-18, 1981, had the purpose of reviewing international activities in space tracking and data systems for civil use in the 1980-2000 time frame. Participants included 225 representatives from industrial and government organizations in eight nations. The nations represented include the United States, France, Germany, India, Japan, Norway, Spain, and Sweden. The major functions of the systems described at the Symposium are related to the initial downlink of telemetry and spacecraft status data, attendant tracking activities, and uplink of spacecraft commands; communication between the associated acquisition sites and central processing and control stations; formulation and implementation of commands that control the spacecraft and its payload; and processing of spacecraft data needed to make command decisions. Attention is given to an overview of current activities and plans, and supporting developments, taking into account the time from 1980 to 1990. New developments are also considered.

    Complex regional pain syndrome (CRPS) is a chronic pain disorder that typically follows trauma or surgery. Suspected CRPS reported after vaccination with human papillomavirus (HPV) vaccines led to temporary suspension of proactive recommendation of HPV vaccination in Japan. We investigated the potential CRPS signal in relation to HPV-16/18-adjuvanted vaccine (Cervarix®) by database review of CRPS cases with independent expert confirmation; a disproportionality analysis and analyses of temporality; an observed versus expected analysis using published background incidence rates; systematic reviews of aggregate safety data, and a literature review. The analysis included 17 case reports of CRPS: 10 from Japan (0.14/100,000 doses distributed) and seven from the United Kingdom (0.08/100,000). Five cases were considered by independent experts to be confirmed CRPS. Quantitative analyses did not suggest an association between CRPS and HPV-16/18-adjuvanted vaccine. Observed CRPS incidence after HPV-16/18 vaccination was statistically significantly below expected rates. Systematic database reviews using search terms varying in specificity and sensitivity did not identify new cases. No CRPS was reported during clinical development and no unexpected results found in the literature. There is not sufficient evidence to suggest an increased risk of developing CRPS following vaccination with HPV-16/18-adjuvanted vaccine. Post-licensure safety surveillance confirms the acceptable benefit-risk of HPV-16/18 vaccination.

    Background Three-dose regimens for human papillomavirus (HPV) vaccines are expensive and difficult to complete, especially in settings where the need for cervical cancer prevention is greatest. Methods We evaluated the vaccine efficacy of fewer than three doses of the HPV16/18 vaccine Cervarix in our Costa Rica Vaccine Trial. Women were randomly assigned to receive three doses of the HPV16/18 vaccine or to a control vaccine and were followed for incident HPV16 or HPV18 infection that persisted in visits that were 10 or more months apart (median follow-up 4.2 years). After excluding women who had no follow-up or who were HPV16 and HPV18 DNA positive at enrollment, 5967 women received three vaccine doses (2957 HPV vaccine vs 3010 control vaccine), 802 received two doses (422 HPV vs 380 control), and 384 received one dose (196 HPV vs 188 control). Reasons for receiving fewer doses and other pre- and post-randomization characteristics were balanced within each dosage group between women receiving the HPV and control vaccines. Results Incident HPV16 or HPV18 infections that persisted for 1 year were unrelated to dosage of the control vaccine. Vaccine efficacy was 80.9% for three doses of the HPV vaccine (95% confidence interval [CI] = 71.1% to 87.7%; 25 and 133 events in the HPV and control arms, respectively), 84.1% for two doses (95% CI = 50.2% to 96.3%; 3 and 17 events), and 100% for one dose (95% CI = 66.5% to 100%; 0 and 10 events). Conclusion Four years after vaccination of women who appeared to be uninfected, this nonrandomized analysis suggests that two doses of the HPV16/18 vaccine, and maybe even one dose, are as protective as three doses.

    Birch, S, Cummings, L, Oxford, SW, and Duncan, MJ. Examining relative age effects in fundamental skill proficiency in British children aged 6-11 years. J Strength Cond Res 30(10): 2809-2815, 2016-The relative age effect (RAE) suggests that there is a clustering of birth dates just after the cutoff used for sports selection in age-grouped sports and that in such circumstances, relatively older sportspeople may enjoy maturational and physical advantages over their younger peers. Few studies have examined this issue in nonselective groups of children, and none have examined whether there is evidence of any RAE in skill performance. The aim of this study was to assess whether there were differences in fundamental movement skill (FMS) proficiency within children placed in age groups according to the school year. Six FMS (sprint, side gallop, balance, jump, catch, and throw) were assessed in 539 school children (258 boys and 281 girls) aged 6-11 years (mean age ± SD = 7.7 ± 1.7 years). We examined differences in these FMS between gender groups and children born in different quarters of the year after controlling for age and body mass index (BMI). For balance, chronological age was significant as a covariate (p = 0.0001) with increases in age associated with increases in balance. Boys had significantly higher sprint mastery compared with girls (p = 0.012), and increased BMI was associated with poorer sprint mastery (p = 0.001). Boys had higher catching mastery than girls (p = 0.003), and children born in Q1 had significantly greater catching mastery than those born in Q2 (p = 0.015), Q3 (p = 0.019), and Q4 (p = 0.01). Results for throwing mastery also indicated higher mastery in boys compared with girls (p = 0.013) and that children born in Q1 had higher throwing proficiency than those born in Q4 (p = 0.038). These results are important if coaches are basing sport selection on measures of skilled performance, particularly in object-control skills. Categorizing children

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

    Aim of the study In the paper clinical cases of individuals diagnosed with lung cancer below the age of 40 years have been analyzed. Material and methods The analysis included: sex, age, clinical symptoms found before and at the moment of diagnosis, character of changes visible in radiological imaging, time that passed from the first symptoms to reporting to a doctor and to establishing a diagnosis, type of diagnostic method used in establishing the final diagnosis, histopathologic type of cancer, degree of cancer progression. Results The results have been compared with a peer group who had been diagnosed 20 years earlier. Currently 7% of patients were diagnosed at the age of 25 or younger, whereas in the previous cohort patients in this age constituted 2%. The predominant pathological type was adenocarcinoma (currently 33%, previously 4%) in contrast to the earlier group in which 57% of patients had small cell lung cancer (57%). The incidence is equally distributed between both sexes, although there is an evident increase in female lung cancer cases. In the majority of patients the clinical presentation is a peripheral mass on chest X-ray. 20% of patients present pleural effusion on diagnosis. Patients reported the following complaints: breathlessness, chest pain, weight loss and fatigue. The majority of cases were diagnosed in advanced stages on the basis of a bronchoscopy acquired specimen. Time course from symptoms to diagnosis tends to be shorter than 20 years ago. PMID:23788919

    This communication will briefly review more than 30 years of research on aging using the nematode Caenorhabditis elegans (“The Worm”) as carried out in the labs of Tom Johnson. We will highlight research directions initiated in the 1980’s, which were exciting for those of us trying to turn over a new leaf in aging research. In this narrative, I will discuss primarily the science that I and my lab have been involved with for the last 30 years. This area has been fascinating to those studying the sociology of science as modern aging research has moved to replace the simplistic, poorly controlled and outright fictitious approaches seen in much of the previous aging research.

    By conducting a case-control study in two university hospitals, we explored the association between modifiable risk behaviours and diarrhoea. Children aged <5 years attending outpatient clinics for diarrhoea were matched by age and sex with controls. Data were collected on family demographics, socioeconomic indicators, and risk behaviour practices. Two rectal swabs and a stool specimen were collected from cases and controls. Samples were cultured for bacterial pathogens using standard techniques and tested by ELISA to detect rotavirus and Cryptosporidium spp. Four hundred cases and controls were enrolled between 2007 and 2009. The strongest independent risk factors for diarrhoea were: presence of another household member with diarrhoea [matched odds ratio (mOR) 4.9, 95% CI 2.8-8.4] in the week preceding the survey, introduction to a new kind of food (mOR 3, 95% CI 1.7-5.4), and the child being cared for outside home (mOR 2.6, 95% CI 1.3-5.2). While these risk factors are not identifiable, in some age groups more easily modifiable risk factors were identified including: having no soap for handwashing (mOR 6.3, 95% CI 1.2-33.9) for children aged 7-12 months, and pacifier use (mOR 1.9, 95% CI 1.0-3.5) in children aged 0-6 months. In total, the findings of this study suggest that community-based interventions to improve practices related to sanitation and hygiene, handwashing and food could be utilized to reduce the burden of diarrhoea in Egyptian children aged <5 years.

    Cervical cancer is a common and an important public health problem for adult women in developing countries. In contrast, cervical cancer incidence is low in Saudi Arabia. High-risk types of human papilloma viruses (HPV16 and HPV18) are the most significant risk factors for cervical cancer. HPV16/18-E6 oncoprotein is associated with HPV etiology, viral persistence and epithelial transformation. Cell cycle protein p16 INK4a (p16) plays an important role in the pathophysiology of cervical carcinomas. The aims of this study were to investigate the expression of HPV16/18-E6 and p16 in uterine cervical carcinomas in Qassim Region--Saudi Arabia, and to relate the results to the established clinicopathological prognostic parameters (age of the patient, educational level, birth control methods, number of pregnancy, smoking status, degree of histological differentiation, clinical stage, and lymph node metastasis) The study included 40 specimens of uterine cervical squamous cell carcinomas diagnosed and confirmed by biopsy. Histopathological classification of cervical tumors cases was performed according to the International Federation of Gynecology and Obstetrics (FIGO). Immunohistochemical analysis for HPV16/18-E6 and p16 were carried out on formalin-fixed paraffin-embedded sections of cervical tissues using avidin-biotin peroxidase method. There was a significant statistical correlation between HPV16/18-E6 expression in cervical carcinoma and nationality, smoking status and size of the tumor. HPV16/18-E6 oncoprotein expression in normal lymphocytes and endothelial cells in the tumor tissues and the adjacent normal cervical tissues suggest the possibility that HPV infection might spread to other organs through blood circulation. P16 expression has been correlated with high grade, stage of cervical SCC and HPV16/18-E6 expression. The current study supports the critical function of p16 and HPV16/18-E6 as specific markers for cervical carcinoma. However the potential for usage

    OBJECTIVE To assess findings of mammography of and interventions resulting from breast cancer screening in women aged 40-49 years with no increased risk (typical risk) of breast cancer. METHODS This cross-sectional study evaluated women aged 40-49 years who underwent mammography screening in a mastology reference center in Recife, PE, Northeastern Brazil, between January 2010 and October 2011. Women with breast-related complaints, positive findings in the physical examination, or high risk of breast cancer were excluded. RESULTS The 1,000 mammograms performed were classified into the following Breast Imaging-Reporting and Data System (BI-RADS) categories BI-RADS 0, 232; BI-RADS 1, 294; BI-RADS 2, 294; BI-RADS 3, 16; BI-RADS 4A, 2; BI-RADS 5, 1. There was one case of grade II invasive ductal carcinoma and various interventions, including 469 ultrasound scans, 53 referrals to mastologists, 11 cytological examinations, and 8 biopsies. CONCLUSIONS Mammography screening in women aged 40-49 years with typical risk of breast cancer led to the performance of other interventions. However, it also resulted in increased costs without demonstrable efficacy in decreasing mortality. PMID:26039396

    A randomized double-blind placebo-controlled phase II trial was conducted to evaluate the efficacy of a prophylactic quadrivalent vaccine targeting the human papillomavirus (HPV) types most frequently associated with cervical cancer (types 16/18) and genital warts (types 6/11) in Japanese women aged 18-26 years. Participants were randomly assigned to either quadrivalent HPV (types 6/11/16/18) L1 virus-like particle vaccine (GARDASIL) (n = 509) or placebo (n = 512). Participants underwent regular gynecological examinations, cervicovaginal sampling for HPV DNA, testing for serum neutralizing antibodies to HPV and Papanicolau testing. The primary end-point was the combined incidence of persistent infection with HPV types 6, 11, 16 or 18 and cervical or external genital disease (i.e. cervical intraepithelial neoplasia, cervical cancer or external genital lesions related to HPV 6, 11, 16 or 18. Primary analyses were done per protocol. Combined incidence of persistent infection or disease with HPV 6, 11, 16 or 18 fell by 87.6% (95% confidence interval [CI], 59.2-97.6; P < 0.001), with HPV 6 or 11 by 73.1% (95% CI, -1.1-97.3; P = 0.0756) and with HPV 16 or 18 by 94.5% (95% CI, 65.2-99.9; P < 0.001) in those assigned vaccine compared with those assigned placebo. The median duration of follow up after month 7 in subjects was 23 months. In addition, the vaccine was well tolerated in Japanese women aged 18-26 years. Quadrivalent HPV vaccine could significantly reduce the acquisition of infection and clinical disease caused by HPV types 6, 11, 16 and 18.

    The prevalence of HPV infection in Latin America is among the highest in the world. A quadrivalent (types 6/11/16/18) human papillomavirus L1 virus-like-particle vaccine has been shown to be 95-100% effective in preventing HPV 6/11/16/18-related cervical and genital disease in women naive to vaccine HPV types. A total of 6,004 female subjects aged 9-24 were recruited from Brazil, Mexico, Colombia, Costa Rica, Guatemala and Peru. Subjects were randomized to immunization with intramuscular (deltoid) injections of HPV vaccine or placebo at enrollment (day 1), month 2 and month 6. Among vaccinated subjects in the per-protocol population from Latin America, quadrivalent HPV vaccine was 92.8 and 100% effective in preventing cervical intraepithelial neoplasia and external genital lesions related to vaccine HPV types, respectively. These data support vaccination of adolescents and young adults in the region, which is expected to greatly reduce the burden of cervical and genital cancers, precancers and genital warts.

    Vaccines are available against human papillomavirus (HPV), the causal agent of cervical and other cancers. Efficacy data from the HPV-16/18 AS04-adjuvanted vaccine clinical trial program were reviewed. Six randomized, controlled phase II/III trials evaluating cervical endpoints enrolled women from diverse populations and geographical locations. The program analyzed extensively the cohorts most relevant from a public health perspective: the total vaccinated cohort (TVC), approximating a general population including those with existing or previous HPV infection, and TVC-naïve, approximating a population of young women before sexual debut. Results show that the vaccine reduces HPV-16/18 infection and associated cervical endpoints in women regardless of age, location, or sexual experience. It provides cross-protection against some non-vaccine oncogenic HPV types and types causing genital warts, and may be effective against vulvar, oral, and anal HPV infection. Early epidemiology data following its introduction suggest a decline in the prevalence of vaccine and some non-vaccine HPV types. PMID:26902666

    Higher perceived age (PA) is reported to be associated with age-related diseases. Because osteoporosis is considered an age-related disease, we hypothesized that age perceived from photographs is associated with bone mineral density (BMD)/trabecular bone score (TBS) when controlled for chronological age. This is a cross-sectional study of 460 women aged 25-93 years. BMD/TBS was measured. Twenty physicians assessed age from facial and whole-body photographs. Residual PA (R(PACA)) was calculated from the regression of PA on chronological age. Participants were divided into "looking old" (LO) or "looking young" (LY). Linear mixed models and general linear models fitted with BMD/TBS as outcome and either R(PACA) or LO/LY as an independent variable, considering chronological age. Estimates of R(PACA) were all negative; i.e., an increase in R(PAC) is associated with lower BMD, consistent with the hypothesis (e.g., β -0.29%; 95% confidence interval (CI) 0.55, 0.03). Statistical significance of the association of age-adjusted facial R(PACA) with BMD was found. Adjusted for body mass index (BMI), menopause, and hormone replacement therapy, higher R(PACA) from all photographic presentations were significantly associated with lower BMD based on statistical significance. BMD/TBS was in all analyses higher in the group LY compared with LO, when adjusted for age and BMI (e.g., β 4.37%; 95 CI 0.62, 8.26), but statistical significance was obtained only from the BMD analyses. A higher PA was significantly associated with a lower BMD/TBD, and the size of association in older women indicates that it might have value as part of the clinical assessment of osteoporotic risk.

    Objectives—To investigate the amount of regular activity and time spent in sedentary occupations in children aged 7–9 years. Sex differences in levels of activity and time and facilities for physical education at school were also examined. Methods—A 10% sample of Dublin National Schools were selected. Parents of children in second class were surveyed. The questionnaire used was a modification of the Modifiable Activity Questionnaire for Adolescents. Teachers of second class were questioned about the time and facilities for physical education in schools. Results—Some 39% of children were participating in hard exercise for at least 20 minutes three or more times a week, with fewer girls (28%) than boys (53%) contributing to this result. A further 57% of children were engaging in at least 20 minutes of light exercise three or more times a week, with no sex differences. Estimated energy expenditure in regular activity was higher in boys than girls. Most (78%) of the children were spending one to three hours a day sedentary in front of a screen. Conclusions—This study provides comprehensive data on physical activity levels in Dublin schoolchildren aged 7–9 years. The amount of inactivity is of concern. Even at this young age, boys are reported to participate in more physical activity than girls. Key Words: physical activity; exercise; children PMID:11477025

    Upon learning the outcome to a problem, people tend to believe that they knew it all along (hindsight bias). Here we report the first study to trace the development of hindsight bias across the lifespan. 194 participants aged 3 to 95 years completed three tasks designed to measure visual and verbal hindsight bias. All age groups demonstrated hindsight bias on all three tasks; however, preschoolers and the elderly exhibited more bias than older children and younger adults. Multinomial processing tree analyses of these data revealed that preschoolers’ enhanced hindsight bias resulted from them substituting the correct answer for their original answer in their recall (a qualitative error). Conversely, older adults’ enhanced hindsight bias resulted from them forgetting their original answer and recalling an answer closer to, but not equal to, the correct answer (a quantitative error). We discuss these findings in relation to mechanisms of memory, perspective-taking, theory of mind, and executive function. PMID:21299327

    Suicide attempts (SA) in children are often considered rare and poorly studied. The aim of this study was to explore the clinical characteristics of SA in children under 12 years of age. A retrospective assessment was conducted in 30 consecutive SAs reported in children under 12 years of age admitted to the emergency department at the Robert-Debré University Hospital (Paris, France) from 2007 to 2010 and the Regional University Hospital (Besançon, France) from 2000 to 2008. All suicide attempters were directly assessed at the somatic and psychiatric level. Patients were 8-11 years old (mean, 10.2±0.8). The sex ratio was 0.9 boys for 1 girl. The leading SA methods were poisoning by medication (53.3%), hanging or strangulation (23.3%), jumping from a height (16.7%), poisoning by chemicals (3.3%), and lesions inflicted by sharp objects (3.3%). In addition, SAs were characterized by high lethality (43.7%) contrasting with their low to moderate suicidal intentionality (43.8% and 56.2%, respectively). In conclusion, we reported that SA in children differs from those of adolescents by their greater lethality related to the methods used, but contrasting with the low intentionality mentioned by these patients.

    Aging in place, an image of growing old in one's home and maintaining one's daily routine, is desired by most older adults. To identify variables promoting such independent living in the oldest-old, we examined the association between living situation of a population-based cohort of 90+ year olds with health and lifestyle variables. Of 1485 participants, 53% still lived in their home at a retirement community designed to foster wellness. Those living at home tended to be healthier, with smaller proportions having chronic diseases or hospitalizations in the preceding year and a greater proportion having normal functional ability. Dementia was the chronic disease most significantly related to living situation. In addition to not having dementia, not using a wheelchair or bath aid, receiving meals on wheels, and being married were jointly related to living at home. With the help of family and friends and with a medical and social support system, many 90+ year olds can age in place. This is often because they have a caregiving spouse or paid caregiver.

    Purpose: To evaluate cause-specific survival (CSS), biochemical progression-free survival (bPFS), and overall survival (OS) in prostate cancer patients aged {>=}75 years undergoing brachytherapy with or without supplemental therapies. Methods and Materials: Between April 1995 and August 2004, 145 consecutive patients aged {>=}75 years underwent permanent prostate brachytherapy. Median follow-up was 5.8 years. Biochemical progression-free survival was defined by a prostate-specific antigen level {<=}0.40 ng/mL after nadir. Patients with metastatic prostate cancer or hormone-refractory disease without obvious metastases who died of any cause were classified as dead of prostate cancer. All other deaths were attributed to the immediate cause of death. Multiple clinical, treatment, and dosimetric parameters were evaluated for impact on survival. Results: Nine-year CSS, bPFS, and OS rates for the entire cohort were 99.3%, 97.1%, and 64.5%, respectively. None of the evaluated parameters predicted for CSS, whereas bPFS was most closely predicted by percentage positive biopsies. Overall survival and non-cancer deaths were best predicted by tobacco status. Thirty-seven patients have died, with 83.8% of the deaths due to cardiovascular disease (22 patients) or second malignancies (9 patients). To date, only 1 patient (0.7%) has died of metastatic prostate cancer. Conclusions: After brachytherapy, high rates of CSS and bPFS are noted in elderly prostate cancer patients. Overall, approximately 65% of patients are alive at 9 years, with survival most closely related to tobacco status. We believe our results support an aggressive locoregional approach in appropriately selected elderly patients.

    Background. We examined risk of newly detected human papillomavirus (HPV) infection and cervical abnormalities in relation to HPV type 16/18 antibody levels at enrollment in PATRICIA (Papilloma Trial Against Cancer in Young Adults; NCT00122681). Methods. Using Poisson regression, we compared risk of newly detected infection and cervical abnormalities associated with HPV-16/18 between seronegative vs seropositive women (15–25 years) in the control arm (DNA negative at baseline for the corresponding HPV type [HPV-16: n = 8193; HPV-18: n = 8463]). Results. High titers of naturally acquired HPV-16 antibodies and/or linear trend for increasing antibody levels were significantly associated with lower risk of incident and persistent infection, atypical squamous cells of undetermined significance or greater (ASCUS+), and cervical intraepithelial neoplasia grades 1/2 or greater (CIN1+, CIN2+). For HPV-18, although seropositivity was associated with lower risk of ASCUS+ and CIN1+, no association between naturally acquired antibodies and infection was demonstrated. Naturally acquired HPV-16 antibody levels of 371 (95% confidence interval [CI], 242–794), 204 (95% CI, 129–480), and 480 (95% CI, 250–5756) EU/mL were associated with 90% reduction of incident infection, 6-month persistent infection, and ASCUS+, respectively. Conclusions. Naturally acquired antibodies to HPV-16, and to a lesser extent HPV-18, are associated with some reduced risk of subsequent infection and cervical abnormalities associated with the same HPV type.

    Deep-water circulation is a critical part of the global conveyor belt that regulates Earth's climate. The bottom (contour)-current component of this circulation is of key significance in shaping the deep seafloor through erosion, transport, and deposition. As a result, there exists a high variety of large-scale erosional and depositional features (drifts) that together form more complex contourite depositional systems on continental slopes and rises as well as in ocean basins, generated by different water masses flowing at different depths and at different speeds either in the same or in opposite directions. Yet, the nature of these deep-water processes and the deposited contourites is still poorly understood in detail. Their ultimate decoding will undoubtedly yield information of fundamental importance to the earth and ocean sciences. The international congress Deep-water Circulation: Processes & Products was held from 16-18 June 2010 in Baiona, Spain, hosted by the University of Vigo. Volume 31(5/6) of Geo-Marine Letters is a special double issue containing 17 selected contributions from the congress, guest edited by F.J. Hernández-Molina, D.A.V. Stow, E. Llave, M. Rebesco, G. Ercilla, D. Van Rooij, A. Mena, J.-T. Vázquez and A.H.L. Voelker. The papers and discussions at the congress and the articles in this special issue provide a truly multidisciplinary perspective of interest to both academic and industrial participants, contributing to the advancement of knowledge on deep-water bottom circulation and related processes, as well as contourite sedimentation. The multidisciplinary contributions (including geomorphology, tectonics, stratigraphy, sedimentology, paleoceanography, physical oceanography, and deep-water ecology) have demonstrated that advances in paleoceanographic reconstructions and our understanding of the ocean's role in the global climate system depend largely on the feedbacks among disciplines.

    Structural evaluations were conducted on several parachute systems to determine the effects of aging on parachute materials. Most of the parachutes were 25 years old. Five 64 ft parachutes were evaluated along with one 4 ft guide surface parachute and three 16.5 ft ribbon parachutes. The parachute systems used in the study were all fabricated from nylon materials. Results were obtained for several material properties such as tensile strength, air permeability and melting point. Military specifications were used as zero-time data base due to lack of raw material data. The results indicate that over a period of about 25 years, parachute nylon materials do not degrade to unacceptable levels. 7 refs., 2 figs., 3 tabs.

    OBJECTIVE: Observed racial disparities in child safety seat use have not accounted for socioeconomic factors. We hypothesized that racial differences in age-appropriate restraint use would be modified by socioeconomic status and child passenger safety information sources. METHODS: A 2-site, cross-sectional tablet-based survey of parents seeking emergency care for their 1- to 12-year-old child was conducted between October 2011 and May 2012. Parents provided self-report of child passenger safety practices, demographic characteristics, and information sources. Direct observation of restraint use was conducted in a subset of children at emergency department discharge. Age-appropriate restraint use was defined by Michigan law. RESULTS: Of the 744 eligible parents, 669 agreed to participate and 601 provided complete responses to key variables. White parents reported higher use of car seats for 1- to 3-year-olds and booster seats for 4- to 7-year-olds compared with nonwhite parents. Regardless of race, <30% of 8- to 12-year-old children who were ≤4 feet, 9 inches tall used a booster seat. White parents had higher adjusted odds (3.86, 95% confidence interval 2.27–6.57) of reporting age-appropriate restraint use compared with nonwhite parents, controlling for education, income, information sources, and site. There was substantial agreement (82.6%, κ = 0.74) between parent report of their child’s usual restraint and the observed restraint at emergency department discharge. CONCLUSIONS: Efforts should be directed at eliminating racial disparities in age-appropriate child passenger restraint use for children <8 years. Booster seat use, seat belt use, and rear seating represent opportunities to improve child passenger safety practices among older children. PMID:24420814

    Quick and parallel genotyping of human papilloma virus (HPV) type 16/18 is carried out by a specially designed giant magnetoimpedance (GMI) based microchannel system. Micropatterned soft magnetic ribbon exhibiting large GMI ratio serves as the biosensor element. HPV genotyping can be determined by the changes in GMI ratio in corresponding detection region after hybridization. The result shows that this system has great potential in future clinical diagnostics and can be easily extended to other biomedical applications based on molecular recognition.

Naturalistic speeding behavior data were collected for up to 52 weeks from volunteer drivers aged 75-94 years (median 80 years, 52% male) living in the suburban outskirts of Sydney. Driving data were collected using an in-vehicle monitoring device. Global Positioning System (GPS) data were recorded at each second and determined driving speed through triangulation of satellite collected location data. Driving speed data were linked with mapped speed zone data based on a service-provider database. To measure speeding behavior, speed events were defined as driving 1 km/h or more, with a 3% tolerance, above a single speed limit, averaged over 30 s. The data contains a row per 124,374 speed events. This article contains information about data processing and quality control. PMID:27294182

    The results of structural evaluations on several parachute systems were examined to determine if any trends could be found that would indicate significant aging in the materials. All of the parachutes were more than 20 years old. Five 64 ft diameter parachutes were evaluated along with three 16.5 ft diameter ribbon parachutes and one 4 ft diameter guide surface parachute. Another group included six 48 ft diameter ribbon parachutes, two 4 ft diameter guide surface parachutes, and two 16.5 ft diameter extraction ribbon parachutes. The parachute systems used in the study were all fabricated from nylon materials. Data were obtained for several material properties such as tensile strength, air permeability and melting point. Military specifications were used as zero-time data base due to lack of raw material data. Generally speaking, after 25 years the material properties of the 64 ft parachutes were within specifications. The same generalization cannot be made for the 48 ft parachutes which were about 23 years old. The explanation for their differences may lie in their respective histories. 10 refs., 2 figs., 5 tabs.

    Since the 1950s, vancomycin has remained a reference treatment for severe infections caused by Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus Vancomycin is a nephrotoxic and ototoxic drug mainly eliminated through the kidneys. It has a large interindividual pharmacokinetic variability, which justifies monitoring its plasma concentrations in patients. This is especially important in patients aged over 80 years, who frequently have renal impairment. However, the pharmacokinetics of vancomycin in this population is very poorly described in the literature. The objective of this work was to propose a model able to predict the pharmacokinetics of vancomycin in very elderly people. First, a population pharmacokinetic model was carried out using the algorithm NPAG (nonparametric adaptive grid) on a database of 70 hospitalized patients aged over 80 years and treated with vancomycin. An external validation then was performed on 41 patients, and the predictive capabilities of the model were assessed. The model had two compartments and six parameters. Body weight and creatinine clearance significantly influenced vancomycin volume of distribution and body clearance, respectively. The means (± standard deviations) of vancomycin volume of distribution and clearance were 36.3 ± 15.2 liter and 2.0 ± 0.9 liter/h, respectively. In the validation group, the bias and precision were -0.75 mg/liter and 8.76 mg/liter for population predictions and -0.39 mg/liter and 2.68 mg/liter for individual predictions. In conclusion, a pharmacokinetic model of vancomycin in a very elderly population has been created and validated for predicting plasma concentrations of vancomycin.

    Background Many observational studies have shown a protective effect of physical activity on cognitive ageing, but interventional studies have been less convincing. This may be due to short time scales of interventions, suboptimal interventional regimes or lack of lasting effect. Confounding through common genetic and developmental causes is also possible. Objectives We aimed to test whether muscle fitness (measured by leg power) could predict cognitive change in a healthy older population over a 10-year time interval, how this performed alongside other predictors of cognitive ageing, and whether this effect was confounded by factors shared by twins. In addition, we investigated whether differences in leg power were predictive of differences in brain structure and function after 12 years of follow-up in identical twin pairs. Methods A total of 324 healthy female twins (average age at baseline 55, range 43-73) performed the Cambridge Neuropsychological Test Automated Battery (CANTAB) at two time points 10 years apart. Linear regression modelling was used to assess the relationships between baseline leg power, physical activity and subsequent cognitive change, adjusting comprehensively for baseline covariates (including heart disease, diabetes, blood pressure, fasting blood glucose, lipids, diet, body habitus, smoking and alcohol habits, reading IQ, socioeconomic status and birthweight). A discordant twin approach was used to adjust for factors shared by twins. A subset of monozygotic pairs then underwent magnetic resonance imaging. The relationship between muscle fitness and brain structure and function was assessed using linear regression modelling and paired t tests. Results A striking protective relationship was found between muscle fitness (leg power) and both 10-year cognitive change [fully adjusted model standardised β-coefficient (Stdβ) = 0.174, p = 0.002] and subsequent total grey matter (Stdβ = 0.362, p = 0.005). These effects were robust in discordant

    Background Testing for high-risk human papillomavirus DNA (HPV test) has gained increasing acceptance as an alternative method to cytology in cervical cancer screening. Compared to cytology, HPV test has a higher sensitivity for the detection of histologic high-grade squamous intraepithelial lesion or worse (HSIL+), but this could lead to a large colposcopy burden. Genotyping for HPV16/18 has been recommended in triaging HPV-positive women. This study was aimed to evaluate the screening performance of HPV testing and the role of genotyping triage in Northern Thailand. Methods A population-based cervical screening program was performed in Chiang Mai (Northern Thailand) using cytology (conventional Pap test) and HPV test (Hybrid Capture 2). Women who had abnormal cytology or were HPV-positive were referred for colposcopy. Cervical samples from these women were genotyped using the Linear Array assay. Results Of 5,456 women, 2.0% had abnormal Pap test results and 6.5% tested positive with Hybrid Capture 2. Of 5,433 women eligible for analysis, 355 with any positive test had histologic confirmation and 57 of these had histologic HSIL+. The sensitivity for histologic HSIL+ detection was 64.9% for Pap test and 100% for Hybrid Capture 2, but the ratio of colposcopy per detection of each HSIL+ was more than two-fold higher with Hybrid Capture 2 than Pap test (5.9 versus 2.8). Genotyping results were available in 316 samples. HPV52, HPV16, and HPV58 were the three most common genotypes among women with histologic HSIL+. Performance of genotyping triage using HPV16/18/52/58 was superior to that of HPV16/18, with a higher sensitivity (85.7% versus 28.6%) and negative predictive value (94.2% versus 83.9%). Conclusions In Northern Thailand, HPV testing with genotyping triage shows better screening performance than cervical cytology alone. In this region, the addition of genotyping for HPV52/58 to HPV16/18 is deemed necessary in triaging women with positive HPV test. PMID

    All-trans retinoic acid (ATRA) has made acute promyelocytic leukemia (APL) a very curable disease also in patients aged >60 years; however, there are only few case reports in very elderly APL patients. To address this issue, we reviewed treatment results in 13 patients aged >70 years with newly diagnosed APL followed at our institution from January 1991 to December 2008. According to Sanz score, seven patients were at low risk, five at intermediate risk, and one at high risk. Induction therapy consisted of ATRA + idarubicin in nine patients (3/9 with reduced idarubicin dosage) and ATRA alone in four patients; in this latter group, however, 2/4 needed to add chemotherapy (CHT) due to hyperleukocytosis during ATRA treatment. All patients achieved both morphological and molecular complete remission (CR) after a median time of 51 [interquartile range (IR) 43-55] and 114 (IR 74-155) days, respectively. Infective complications were observed in 10/13 patients, APL differentiation syndrome in 3/13 patients. Twelve patients received consolidation therapy, followed by maintenance treatment in nine patients. Five patients relapsed after 7, 8, 11, 35, and 56 months. At present, seven patients are still alive, five died due to disease progression (four) or senectus while in CR (one), and one was lost to follow-up while in CR. The 5-year event-free survival was 56.1 % (95 % CI, 26.0-86.2); the 5-year overall survival (OS) was 64.5 % (95 % CI, 35.6-93.4). ATRA-based treatment of APL is safe and effective also in very elderly patients, with long-lasting disease-free OS. PMID:25186786

    For middle and low-income countries, the cost of HPV vaccines remains challenging. We conducted an open-label nonrandomized clinical trial evaluating immune response to the HPV-16/18 AS04-adjuvanted vaccine administered on a standard (months (M) 0-1-6) versus extended schedule (M 0-6-60) at 7, 21, 60, 72 and 120 months post-vaccination. Participants were females recruited in Morelos, Mexico: 474 girls aged 9-10 years and 500 women aged 18-24 years receiving a standard schedule, and 1026 girls aged 9-10 years receiving an extended schedule (currently the girls in the extended schedule had received only the first 2 doses). This report presents the interim analysis results for non-inferiority between the regimes conducted with the current available data at 21 months after the first dose, with serum antibodies assessed by ELISA. A pre-stated margin of non-inferiority was defined by post-vaccination geometric mean titer (GMT) ratio (upper 95% confidence interval [CI]≤2.0) between the standard and the two-dose schedule in girls at month 21. Immune response to the vaccine was strongest in adolescent girls and in the 3-dose group. Statistical non-inferiority of the two-dose versus three-dose groups was demonstrated. At 21 months, comparing the adolescent 2-dose versus 3-dose groups, the GMT ratio and 95% CI were 1.66 (1.55-1.81) and 1.67 (1.51-1.86) for HPV16 and 18, respectively. The two-dose regimen was non-inferior when compared to the three-dose response in same-age girls and with women aged 18-24 years after 21 months of follow-up. The reduction in the number of doses from the current three-dose schedule may lower overall costs associated with the vaccination and increase accessibility and compliance with the recommended dosing of the HPV vaccine.

    Condyloma acuminatum is an anogenital lesion caused by human papillomavirus (HPV) infection, a common sexually transmitted disease. It usually affects the external genitalia while urethral and/or bladder involvement is rare. HPV types are classified into three categories depending on their oncogenic potential: low risk (type 6, 11, 42, 43, 44, 59, 66, 68, 70), intermediate risk (type 30, 31, 33, 34, 35, 39, 40, 49, 51, 52, 53, 57, 58, 63, 64) and high risk (type 16, 18, 45, 56). High-risk and intermediate-risk HPV-DNA types, together with other co-factors still to be defined, are responsible for over 90% of the cases of anogenital pre-malignant and malignant tumours. We report a unique case of a urinary bladder condyloma acuminatum positive for HPV 16/18 DNA, presented as the primary and only site of the disease in an immunocompetent patient. We review the treatment and follow-up strategies of this rare lesion.

    Baseline human papillomavirus (HPV) prevalence and type distribution were evaluated in young Chinese women enrolled in a clinical trial of an HPV vaccine (ClinicalTrials.gov registration NCT00779766). Cervical specimens and blood samples were collected at baseline from women aged 18-25 years (n = 6,051) from four sites across Jiangsu province. Cervical specimens were tested for HPV DNA by SPF10 PCR-DEIA-LiPA25 version 1, and HPV-16/18 type-specific polymerase chain reaction. Anti-HPV-16 and anti-HPV-18 antibody titres were quantified by enzyme-linked immunosorbent assay. At baseline, 15.3% of women were DNA positive for any of 14 HPV high-risk (hr) types (HPV-16/18/31/33/35/39/45/51/52/56/58/59/66/68). The most commonly detected hrHPV types in cervical specimens were HPV-52 (4.0%) and HPV-16 (3.7%). High-risk HPV DNA-positivity increased with severity of cytological abnormalities: 39.3% in atypical squamous cells of undetermined significance, 85.0% in low-grade squamous intraepithelial lesions and 97.8% in high-grade squamous intraepithelial lesions (HSIL). The hrHPV types most frequently detected in HSIL were HPV-16 (63.0%), HPV-18 (17.4%), HPV-52 (17.4%), HPV-58 (15.2%) and HPV-33 (15.2%). The hrHPV types most frequently detected in cervical intraepithelial neoplasia 2+ were HPV-16 (66.1%), HPV-33 (16.1%), HPV-52 (16.1%), HPV-58 (14.5%) and HPV-51 (11.3%). Multiple hrHPV infections were reported for 24.4% of hrHPV DNA positive women. Regardless of baseline HPV DNA status, 30.5% and 16.0% of subjects were initially seropositive for anti-HPV-16 and anti-HPV-18, respectively. In conclusion, the high baseline seropositivity rate and intermediate prevalence of cervical hrHPV types in Chinese women aged 18-25 years underlines the importance of early HPV vaccination in this population.

    ABSTRACT Research reports indicate that vitamin B12 levels show racial differences, which suggests that using the reference ranges of varied populations may lead to inaccurate results. This study aimed to determine normal serum levels of vitamin B12 among children and young people in the Konya region of Turkey. It evaluated 1,109 samples; 54 were from cord-blood and 1,055 were from healthy subjects aged 0-24 year(s), who were admitted to primary healthcare centres. The normal reference levels obtained for vitamin B12 at 2.5-97.5 percentile (P2.5-P97.5) range were 127-606 pg/mL for girls, 127-576 pg/mL for boys, and 127-590 pg/mL for the entire study group. The reported reference values for vitamin B12 in other studies were higher than the current results. Vitamin B12 levels vary from country to country; comparisons between countries may not be valid, and normal levels for each population should be obtained. PMID:25895195

    The NSF/SNL joint mechanics workshop, held in Arlington, Virginia, 16-18 October, 2006, attempted to assess the current state of the art for modeling joint mechanics for the purpose of structural dynamics calculation, to identify the underlying physics issues that must be addressed to advance the field, and to propose a path forward. Distinguished participants from several countries representing research communities that focus on very different length and time scales identified multiple challenges in bridging those scales. Additionally, two complementary points of view were developed for addressing those challenges. The first approach - the 'bottom-up' perspective - attempts to bridge scales by starting from the smallest length scale and working up. The other approach starts at the length scale of application and attempts to deduce mechanics at smaller length scales through reconciliation with laboratory observation. Because interface physics is a limiting element of predictive simulation in defense and transportation, this issue will be of continuing importance for the foreseeable future.

    2012-01-01

    High-risk human papillomavirus (HPV) especially HPV-16 and HPV-18 types are speculated to be important risk factors in non-smoking associated lung cancer in Asia. Increasing evidence has demonstrated that HPV oncoproteins may contribute to lung tumorigenesis and cell transformation. Importantly, HPV 16/18 E6 and E7 oncoproteins can mediate expression of multiple target genes and proteins, such as p53/pRb, VEGF, HIF-1α, cIAP-2, and hTERT, and contribute to cell proliferation, angiogenesis and cell immortalization through different signaling pathways in lung cancer. This article provides an overview of experiment data on HPV-associated lung cancer, describes the main targets on which HPV E6/E7 oncoproteins act, and further discusses the potential signaling pathways in which HPV E6/E7 oncoproteins are involved. In addition, we also raise questions regarding existing problems with the study of HPV-associated lung cancer.

    Objective To investigate the procedural outcomes and the long-term survival of patients undergoing transcatheter aortic valve implantation (TAVI) and compare study results of patients ≤ 80 years and patients > 80 years old. Methods A total of 240 patients treated with TAVI were divided into two groups according to age ≤ 80 years (n = 105; 43.8%) and > 80 years (n = 135; 56.2%). The baseline characteristics and the procedural outcomes were compared between these two groups of patients. Results With the exception of peripheral artery disease and hypercholesterolemia, which were more frequently observed in the older age group, baseline characteristics were comparable between groups. Complication rates did not differ significantly between patients ≤ 80 years and patients > 80 years. There were no differences in 30-day mortality rates between patients aged ≤ 80 years and patients > 80 years old (9.5% vs. 7.4%, respectively; P = 0.557). After a median follow-up of 28 months (interquartile range: 16–42 months), 50 (47.6%) patients aged ≤ 80 years died compared to 57 (42%) deaths in the group of patients > 80 years old (P = 0.404). Conclusion The results of the present single center study showed that age did not significantly impact the outcomes of TAVI. PMID:26918010

    Objectives Persistence of human papillomaviruses (HPVs) is necessary for cervical carcinogenesis. We evaluated incidence and duration of type-specific HPV infections and the influence of age and number of sexual partners. Methods Data were obtained from 553 women (15–25 years), who were seronegative and DNA-negative for high-risk HPV (HR-HPV) types and were enrolled in the placebo arm of a randomised trial of the HPV-16/18 vaccine (NCT00689741/NCT00120848). They were followed for 6.3 years. Cervicovaginal samples were self-collected at 3-month intervals for up to 27 months, and cervical samples were collected by clinicians at 6-month intervals until study end. Samples were tested for HPV types using a broad-spectrum PCR assay. Incidence rate ratios (RRs) and 95% CIs were used to estimate the association among age, sexual habits and HPV acquisition. Results Incidence rates (95% CI) using cervical samples were 11.8 (10.4 to 13.4) and 5.6 (4.7 to 6.6) per 1000 women-months for HR-HPVs and low-risk HPVs (LR-HPVs), respectively. Equivalent rates in combined cervicovaginal and cervical samples were 17.2 (15.4 to 19.2) and 6.9 (5.9 to 8.0), respectively. 54 per cent of HR-HPV types from combined cervicovaginal and cervical samples persisted for 1 year compared with 32.3% for LR-HPV types. The risk of acquiring any HPV infection was higher among women aged <21 years (RR=1.33, 95% CI 1.1 to 1.7) and women having >1 sexual partner (RR=1.83, 95% CI 1.4 to 2.4) at baseline. Conclusions HR-HPV infections were more common and lasted longer on average than LR-HPV infections. HPV acquisition was more common in younger women with multiple sexual partners.

    This study was designed to test the reliability of using the third molars to demarcate between child and adult status. A total of 2000 dental panoramic tomographs were used for assessment of the calculated age using the 8-stage system of tooth development and applied to all four third molars. The LL8 was also assessed using this 8-stage system. For each tooth development stage, the Normal distribution and percentile summary data were estimated. The calculated dental age compared with the chronological age was statistically significantly different (p < 0.001) for both females and males giving underestimates of the true age. Comparison of single tooth dental age and chronological age was only slightly different. The most important finding is that the assignment to above or below the 18-year threshold, in the age range 17 years to 19 years, could be wrong on up to 50% of occasions.

    As a foundation for studies of human cognitive aging, it is important to know the stability of individual differences in cognitive ability across the life course. Few studies of cognitive ability have tested the same individuals in youth and old age. We examined the stability and concurrent and predictive validity of individual differences in the same intelligence test administered to the same individuals (the Lothian Birth Cohort of 1921, N = 106) at ages 11 and 90 years. The correlation of Moray House Test scores between age 11 and age 90 was .54 (.67 when corrected for range restriction). This is a valuable foundation for estimating the extent to which cognitive-ability differences in very old age are accounted for by the lifelong stable trait and by the causes of cognitive change across the life course. Moray House Test scores showed strong concurrent and predictive validity with "gold standard" cognitive tests at ages 11 and 90.

    2016-01-15

    The few extant reports of longitudinal white matter (WM) changes in healthy aging, using diffusion tensor imaging (DTI), reveal substantial differences in change across brain regions and DTI indices. According to the "last-in-first-out" hypothesis of brain aging late-developing WM tracts may be particularly vulnerable to advanced age. To test this hypothesis we compared age-related changes in association, commissural and projection WM fiber regions using a skeletonized, region of interest DTI approach. Using linear mixed effect models, we evaluated the influences of age and vascular risk at baseline on seven-year changes in three indices of WM integrity and organization (axial diffusivity, AD, radial diffusivity, RD, and fractional anisotropy, FA) in healthy middle-aged and older adults (mean age=65.4, SD=9.0years). Association fibers showed the most pronounced declines over time. Advanced age was associated with greater longitudinal changes in RD and FA, independent of fiber type. Furthermore, older age was associated with longitudinal RD increases in late-developing, but not early-developing projection fibers. These findings demonstrate the increased vulnerability of later developing WM regions and support the "last-in-first-out" hypothesis of brain aging.

    BACKGROUND: The authors studied the results Of silicone ring vertical gastroplasty (SRVG) in Patients aged 50 years and older. METHODS: The early and late Postoperative results in 28 patients aged.50 Years or older undergoing SRVG were reviewed retrospectively, The results were compared to those of 370 Patients Younger than 50 years operated during the same period. RESULTS: There was no Postoperative mortality among patients aged 50 years and older. There was a significantly higher incidence Of Pulmonary embolus and wound infection among patients aged 50 years and older (P < 0.05). The weight loss did not differ significantly between the two studied age groups. CONCLUSION: SRVG may performed on patients aged 50 years or older with acceptable complication rate and favorable postoperative results. PMID:10729875

    2015-12-01

    Cross-sectional studies of cognitive aging compare age groups at 1 time point. It is unclear from such studies whether age-related cognitive differences remain stable across time. We present a cross-sectional investigation of vocabulary scores of 2,000 younger and older adults collected across 16 years, using the same laboratory and protocol. We found a steady decrease with year of testing and an advantage for older adults. An additive relation between age group and year of testing implied that age-related differences in vocabulary are independent of changes over time, suggesting that younger and older adults are similarly affected by changes in word usage.

    This study reviewed 66 intertrochanteric fractures in patients younger than 40 years old (average 33.0 years old; range 17-40 years old). In contrast to the usual population with intertrochanteric fractures, the factors male predominance (46/66), less pre-injury comorbidity (9/66), more outdoor high energy trauma (47/66), and more associated injuries (32/66) were evident. The distribution of associated injuries was wide. Some of them were life threatening. According to Boyd's classification, 20 were type I, 24 were type II, 13 were type III, and 9 were type IV. Twenty-nine were stable, and 37 were unstable. Stratified by the mechanism of injury, the difference in distribution between the subgroups was significant (p = 0.027, two-tail Fisher's exact test). Simple falls only caused Boyd type I and II fractures. Boyd type III or IV fractures were found more often after vehicular trauma or falls from a height. All the intertrochanteric fractures healed on average 70.5 days (range 31-213 days) after operation. The fractures resulting from vehicular trauma or fall from a height healed significantly more slowly (p = 0.02, univariant log-rank test). There were 6 intertrochanteric fracture-related complications. The mechanism of injury determines the character of intertrochanteric fractures in young adults. Given tougher bone stock, better healing ability, and less co-morbidity, proper management can lead to healing of all intertrochanteric fractures. The extent of functional recovery was also determined by the associated injuries.

    Introduction The aim of this study was to evaluate the treatment outcomes of differentiated thyroid cancer in Saudi patients aged above 60 years. Materials and methods Comparative analysis was performed in 252 patients aged 46–60 years (Group A) and 118 patients aged above 60 years (Group B), who had thyroidectomy, radioactive iodine-131, and thyroid-stimulating hormone suppression therapy between July 2000 and December 2012. Different clinicopathological features, treatment, complications, disease-free survival, and overall survival rates were compared. Results Mean age of patients in Group A was 51.9 years (range: 46–60), and mean age of those in Group B was 68.6 years (range: 62–97). Group B patients had higher positive lymph nodes (43.2%), P=0.011. The frequency of extrathyroidal extension, multifocality, and lymphovascular space invasion was seen more in Group B than in Group A. Postsurgical complications (permanent hypoparathyroidism, bleeding, and wound infections) were also seen more in Group B (P=0.043, P=0.011, and P=0.021, respectively). Group B patients experienced more locoregional recurrences (11.0%, P=0.025); similarly, more distant metastases were observed in Group B (15.3%, P=0.003). The 10-year disease-free survival rates were 87.6% in Group A and 70.8% in Group B (P<0.0001). Conclusion Differentiated thyroid cancer in patients aged above 60 years are more aggressive biologically and associated with a worse prognosis, and the morbidity is significantly high as compared to patients aged below 60 years.

  9. Measuring years of inactivity, years in retirement, time to retirement, and age at retirement within the Markov model.

    PubMed

    Skoog, Gary R; Ciecka, James E

    2010-08-01

    Retirement-related concepts are treated as random variables within Markov process models that capture multiple labor force entries and exits. The expected number of years spent outside of the labor force, expected years in retirement, and expected age at retirement are computed-all of which are of immense policy interest but have been heretofore reported with less precisely measured proxies. Expected age at retirement varies directly with a person s age; but even younger people can expect to retire at ages substantially older than those commonly associated with retirement, such as age 60, 62, or 65. Between 1970 and 2003, men allocated most of their increase in life expectancy to increased time in retirement, but women allocated most of their increased life expectancy to labor force activity. Although people can exit and reenter the labor force at older ages, most 65-year-old men who are active in the labor force will not reenter after they eventually exit. At age 65, the probability that those who are inactive will reenter the labor force at some future time is .38for men and .27 for women. Life expectancy at exact ages is decomposed into the sum of the expected time spent active and inactive in the labor force, and also as the sum of the expected time to labor force separation and time in retirement.

  10. Screening for breast cancer and mortality reduction among women 40-49 years of age.

    PubMed

    Kopans, D B

    1994-07-01

    The recent withdrawal of screening support for women ages 40-49 years is not scientifically supported. The subgroup analyses that have been used severely compromise the statistical power of the trials. None of the trials has the statistical power to be able to provide clear proof of benefit for screening women ages 40-49 years because none of the trials involved sufficient numbers of women in these age groups. Despite having not been designed to evaluate women ages 40-49 years as a separate group, five of the eight randomized, controlled trials have demonstrated mortality reductions for these women that range from 22% to 49%. In addition, data from other nonrandomized trials show that there is no difference in survival for women ages 40-49 years than for women ages 50-59 years. The detection rate for small, early cancers, using modern mammography, is similar for women in both decades. There is no scientific reason to believe that there is a sudden change in detection or cure at age 50 years, or even at menopause. The available data suggest that women ages 40-49 years can benefit from screening, just as can women ages 50-59 years.

    Objective To clarify if older pregnant women were more likely to have adverse perinatal outcomes when compared to women at an ideal age to have a child. Methods The groups were divided according to age groups: under 20 years, ≥20 to <40 years, and ≥40 years. Results During the period from January 1st, 2008, to December 31st, 2008, there were 76 births from patients younger than 20 years and 91 births from patients aged 40 years or over. To form a third group with intermediate age, the data of 92 patients aged 20 to 40 years were obtained, totaling 259 patients. Patients aged 40 or older had a statistically greater number of cesarean sections and less use of forceps or normal deliveries (p<0.001). The use of spinal anesthesia was statistically higher among those aged 40 years or more (p<0.001). The frequency of male newborns was statistically higher in older patients, a group with statistically fewer first pregnancies (p<0.001). The frequency of premature newborns was statistically higher in patients aged 40 years or more (p=0.004). Conclusion It is crucial to give priority to aged women, so that prenatal care will be appropriate, minimizing maternal complications and improving perinatal outcomes in this unique group.

    OBJECTIVE: To assess hamstrings and quadriceps strength of basketball players ages 11-13 and 15-17 years. DESIGN AND SETTING: This cross-sectional study occurred during the 2000 American Youth Basketball Tour National Tournament. We investigated whether sex- or age-related strength differences existed among study participants. SUBJECTS: Forty-one tournament participants (22 girls, 19 boys; 11-13 or 15-17 years old) who reported no history of knee sprain or surgery were recruited. MEASUREMENTS: We used a Cybex II dynamometer to obtain isokinetic concentric peak torques relative to body mass (Nm/kg) at 60 degrees /s for hamstrings and quadriceps bilaterally. From average peak torques, we determined ipsilateral hamstrings:quadriceps and homologous muscle-group ratios. RESULTS: Correlations between hamstrings and quadriceps strength measures ranged from 0.78 to 0.97. Players 15-17 years old had greater relative hamstrings and quadriceps strength than 11- to 13-year-old athletes. Age and sex interacted significantly for quadriceps strength. The quadriceps strength of 15- to 17-year-old girls did not differ from that of 11- to 13-year-old girls, whereas 15- to 17-year-old boys had stronger quadriceps than 11- to 13-year-old boys. Boys 15-17 years old had greater quadriceps strength than girls 15-17 years old. CONCLUSIONS: This study is unique in providing normative data for the hamstrings and quadriceps strength of basketball players 11-13 and 15-17 years old. Age-related strength differences did not occur consistently between the sexes, as girls 11-13 and 15-17 years old had similar relative quadriceps strength.

    To determine the predictive and prognostic value of koilocytosis, expression of E6 HPV types 16/18, p16INK4a, p53 in patients with locally advanced HPV-associated squamous cell carcinoma of oral cavity and oropharynx. In biopsy specimens of squamous cell carcinomas of oral cavity and oropharynx from 60 patients performed koylocytes count, immunohistochemical detection of HPV 16/18 types E6 protein, proteins p16INK4a and p53. Koilocytosis was detected in 50 patients (83.3%); in all 60 patients (100%) were simultaneous expression of p16INK4a and E6 HPV types 16/18; p53 expression was found in 37 patients (61.7%). After combined treatment (induction chemotherapy followed by radiotherapy) stable disease (SD) was detected in 11 patients (18.3%), partial response (PR) - in 25 patients (41.7%), complete response (CR) - in 24 patients (40.0%). There were no cases of disease progression. Treatment effect correlated with expression of p16INK4a (ρ = 0.3, p = 0.024) and expression of p53 (ρ = - 0.3, p = 0.019). Patients with a low expression of p16INK4a (2 points) and high expression of p53 (4 "+") had a high level of SD and had no CR. For all patients, the median of overall survival (OS) was 17 months, 1-year cumulative survival rate was 66.7%, 2-year cumulative survival rate - 35.0%. Median of overall survival was correlated with koilocytosis (ρ=0.5, p<0,001) and expression of E6 HPV types 16/18 (ρ=0.9, p<0.001), p16INK4a (ρ=0.9, p=0.037), p53 (ρ=-0.9; p<0.001). Patients with low expression of p53 (0 and 1 "+") had cumulative 1-year survival rates 87% and 90%, respectively (p<0.001), 2-year survival rates - 52% and 80%, respectively (p=0.015). In the Cox proportional hazards model the significant prognostic factors were prevalence of primary tumor (OR 2.2, 95% CI 1.3 - 3.5, p=0.003) and p53 expression (OR 1.3, 95% CI 1.1=1.7, p=0.016). High expression of p16INK4a associated with a high effect of combined treatment, high expression of a p53 - with low effect of

    The effects of age and gender on sleep EEG power spectral density were assessed in a group of 100 subjects aged 20 to 60 years. We propose a new statistical strategy (mixed-model using fixed-knot regression splines) to analyze quantitative EEG measures. The effect of gender varied according to frequency, but no interactions emerged between age and gender, suggesting that the aging process does not differentially influence men and women. Women had higher power density than men in delta, theta, low alpha, and high spindle frequency range. The effect of age varied according to frequency and across the night. The decrease in power with age was not restricted to slow-wave activity, but also included theta and sigma activity. With increasing age, the attenuation over the night in power density between 1.25 and 8.00 Hz diminished, and the rise in power between 12.25 and 14.00 Hz across the night decreased. Increasing age was associated with higher power in the beta range. These results suggest that increasing age may be related to an attenuation of homeostatic sleep pressure and to an increase in cortical activation during sleep.

  4. Radiocarbon ages and age models for the past 30,000 years in Bear Lake, Utah and Idaho

    Radiocarbon analyses of pollen, ostracodes, and total organic carbon (TOC) provide a reliable chronology for the sediments deposited in Bear Lake over the past 30,000 years. The differences in apparent age between TOC, pollen, and carbonate fractions are consistent and in accord with the origins of these fractions. Comparisons among different fractions indicate that pollen sample ages are the most reliable, at least for the past 15,000 years. The post-glacial radiocarbon data also agree with ages independently estimated from aspartic acid racemization in ostracodes. Ages in the red, siliclastic unit, inferred to be of last glacial age, appear to be several thousand years too old, probably because of a high proportion of reworked, refractory organic carbon in the pollen samples. Age-depth models for five piston cores and the Bear Lake drill core (BL00-1) were constructed by using two methods: quadratic equations and smooth cubic-splinefits. The two types of age models differ only in detail for individual cores, and each approach has its own advantages. Specific lithological horizons were dated in several cores and correlated among them, producing robust average ages for these horizons. The age of the correlated horizons in the red, siliclastic unit can be estimated from the age model for BL00-1, which is controlled by ages above and below the red, siliclastic unit. These ages were then transferred to the correlative horizons in the shorter piston cores, providing control for the sections of the age models in those cores in the red, siliclastic unit. These age models are the backbone for reconstructions of past environmental conditions in Bear Lake. In general, sedimentation rates in Bear Lake have been quite uniform, mostly between 0.3 and 0.8 mm yr-1 in the Holocene, and close to 0.5 mm yr-1 for the longer sedimentary record in the drill core from the deepest part of the lake.

    Purpose The purpose of this study is to evaluate the impact of high-risk human papillomaviruses (HPVs) other than HPV 16/18 on the natural course of atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesion (LSIL). Materials and Methods The study population was derived from the Korean HPV cohort (2010-2014). Women aged 20 to 60 who satisfied the criteria of having both HPV infection and abnormal cervical cytology of either ASC-US or LSIL were recruited from five institutions nationwide. Enrolled patients underwent cervical cytology and HPV DNA testing every 6 months. Results A total of 1,158 patients were enrolled. The 10 most common HPV types were HPV 16 (12.3%), 58 (10.0%), 56 (8.8%), 53 (8.4%), 52 (7.7%), 39 (6.2%), 18 (6.0%), 51 (5.7%), 68 (5.1%), and 66 (4.6%). Among these patients, 636 women were positive for high-risk HPVs other than HPV 16 or 18, and 429 women were followed for more than 6 months. Cytology evaluations showed progression in 15.3% of women, no change in 22.6%, and regression in 62.1% of women at 12 months. In cases of HPV 58 single infection, a more highly significant progression rate, compared to other high-risk types, was observed at 6 months (relative risk [RR], 3.3; 95% confidence interval [CI], 2.04 to 5.30; p < 0.001) and 12 months (RR, 5.03; 95% CI, 2.56 to 9.91; p < 0.001). Conclusion HPV genotypes numbered in the 50s were frequent in Korean women with ASC-US and LSIL. HPV 58 was the second most common type, with a high progression rate of cervical cytology.

    This study explored the age-related deterioration in stretch-shortening cycle (SSC) muscle power and concurrent force-velocity properties in women and men across the adult life span. A total of 315 participants (women: n = 188; men: n = 127) aged 18-81 years performed maximal countermovement jumps on an instrumented force plate. Maximal SSC leg extension power expressed per kg body mass (Ppeak) was greater in men than in women across the adult age span (P < 0.001); however, this gender difference was progressively reduced with increasing age, because men showed an ∼50% faster rate of decline in SSC power than women (P < 0.001). Velocity at peak power (VPpeak) was greater in men than in women (P < 0.001) but declined at a greater rate in men than in women (P = 0.002). Vertical ground reaction force at peak power (FPpeak) was higher in men than in women in younger adults only (P < 0.001) and the age-related decline was steeper in men than in women (P < 0.001). Men demonstrated a steeper rate of decline in Ppeak than women with progressive aging. This novel finding emerged as a result of greater age-related losses in men for both force and velocity. Consequently, maximal SSC power production was observed to converge between genders when approaching old age.

  7. Predictors and characteristics of successful aging among men: a 48-year longitudinal study.

    PubMed

    Westermeyer, Jerry F

    2013-01-01

    To explore dimensions of successful aging, 71 men were selected for healthy adjustment and were prospectively studied in young adulthood (average age 20) and reassessed in 32-year and 48-year follow-ups. Despite an increase of medical problems, most men maintained healthy adjustment in early old age. At both follow-ups, successful young adult predictors of favorable overall outcome included good peer social adjustment, an absence of troubled parental discipline, and an absence of immature defensive behaviors when angry. However, young adult factors were more predictive of outcomes in middle age than in early old age, as predictor effect sizes decreased between the first follow-up and the second follow-up 16 years later. Findings support the possibility of both favorable and unfavorable changes in the second half of life that may diminish the impact of some young adult characteristics and family environments on adjustment in early old age.

    Background: There is increasing concern about the potential effects of traffic-related air pollution (TRAP) on the developing brain. The impact of TRAP exposure on childhood behavior is not fully understood because of limited epidemiologic studies. Objective: We explored the association between early-life exposure to TRAP using a surrogate, elemental carbon attributed to traffic (ECAT), and attention deficit/hyperactivity disorder (ADHD) symptoms at 7 years of age. Methods: From the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) birth cohort we collected data on exposure to ECAT during infancy and behavioral scores at 7 years of age. Children enrolled in CCAAPS had at least one atopic parent and a birth residence either < 400 m or > 1,500 m from a major highway. Children were followed from infancy through 7 years of age. ECAT exposure during the first year of life was estimated based on measurements from 27 air sampling sites and land use regression modeling. Parents completed the Behavioral Assessment System for Children, 2nd Edition, when the child was 7 years of age. ADHD-related symptoms were assessed using the Hyperactivity, Attention Problems, Aggression, Conduct Problems, and Atypicality subscales. Results: Exposure to the highest tertile of ECAT during the child’s first year of life was significantly associated with Hyperactivity T-scores in the “at risk” range at 7 years of age, after adjustment [adjusted odds ratio (aOR) = 1.7; 95% CI: 1.0, 2.7]. Stratification by maternal education revealed a stronger association in children whose mothers had higher education (aOR = 2.3; 95% CI: 1.3, 4.1). Conclusions: ECAT exposure during infancy was associated with higher Hyperactivity scores in children; this association was limited to children whose mothers had more than a high school education.

    2016-09-01

    Introduction The gradual shift of general paediatric surgery (GPS) provision from district general hospitals (DGH) to specialised units is well recognised in the UK. The consequences of centralisation include a reduction in exposure to GPS for current surgical trainees. The GPS practice of a DGH is examined here. Methods All operations performed on children aged under 5 years over a 5-year period were identified using the local electronic operation database. Electronic hospital records and clinic letters were accessed to collect data on demographics, operations performed and outcome measures. Results 472 GPS operations were performed on children between the age of 22 days and 5 years between 2009 and 2014, of which 43 were on an emergency basis and 105 were performed on patients aged less than 1 year. Three patients were admitted following day case surgery. Six patients were readmitted within 30 days. Complication rates for all procedures and the four most common procedures were similar to those found in published literature. Conclusions GPS for patients aged less than 5 years is comparatively safe in the DGH setting. The training opportunities available at DGHs are invaluable to surgical trainees and vital for sustaining the future provision of GPS by such hospitals. PMID:27269243

    The interindividual age-related decrease in baroreflex sensitivity (BRS) was reported in many cross-sectional studies. However, the long-term intraindividual decrease in BRS has never been confirmed by longitudinal studies. Data obtained from a 5-year prospective study designed to assess the 5-year stress effects on blood pressure (BP) provided the opportunity to assess longitudinal aging process on spectrally determined BRS (S-BRS) using the cross spectral analysis. This analysis was carried out in 205 men aged between 18 and 50 years who had 2 valid beat to beat BP recordings (Finapress) at a mean 5-year interval. At inclusion and at end of follow-up, S-BRS was significantly correlated with age (r=-0.50, P<0.001, r=-0.33, P<0.001 respectively). Interestingly, the slopes and the intercepts were not significantly different at a 5-year interval. This result is in favor of the good reproducibility of S-BRS. The attenuation with age of S-BRS was calculated at 3.6% a year. This decrease was slightly higher than the one obtained with the baseline data (2.3% per year). This longitudinal study provided, for the first time, an estimate of the slope of the age-related physiological S-BRS decrease in a mid-aged healthy male population. Our findings reinforce the interest of evaluating spontaneous BRS reported to predict hypertension and cardiovascular events in various populations.

  11. Thirty years of the United Nations and global ageing: an Australian perspective.

    PubMed

    Kendig, Hal; Lucas, Nina; Anstey, Kaarin J

    2013-10-01

    Over the past three decades, the United Nations (UN) has slowly devoted increasing attention to global ageing. Concern for individually based welfare or health-care programs for older people in developed countries has progressed to also consider the contributions of older people and implications of ageing for socioeconomic advancement in developing countries, including those in Asia Oceania. These shifts are evident in the International Plans of Action on Ageing from Vienna in 1982 to Madrid in 2002; recent 10-year reviews of the Madrid Plan; and current advocacy for inclusion of ageing in the influential UN Millennium Plan post-2015. Australia has demonstrated progressive policies and contributed to ageing developments by the UN, International Federation on Ageing the World Health Organization and the International Association of Gerontology. Key ideas driving further action are the importance of valuing people at all ages, addressing inequalities over the life-course and implementing human rights approaches to ageing.

    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 <5y. We employed the WHO BMI-age standardized curves for teenagers between 15–19y. In women >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 5y. 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 19y. 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

    Preserving physical and cognitive function is crucial to successful aging. The objective of this study is to determine how many 87-year-old community-dwelling subjects continued to age successfully, according to a definition using a quantitative approach, and to assess the predictive value of certain factors evaluated 2 years previously. A total of 162 participants were assessed. Sociodemographic variables, the Barthel Index (BI), the Spanish version of the Mini-Mental State Examination (MEC), the Mini Nutritional Assessment (MNA), the Charlson Index, the Gait Rating Scale, social risk, quality of life, prevalent chronic diseases, and chronic drug prescription were collected. All subjects with scores over 90 points on the BI and above 23 points on the MEC were compared with the rest of the participants. A multiple regression analysis was performed. With the selected criteria, 90 (61.6%) community-dwelling subjects continued to age successfully. The multiple logistic regression analysis showed that the following were significantly associated with continued successful aging: A higher level of studies (p<0.02, odds ratio [OR] 3.223, 95% confidence interval [CI] 1.158-8.975), better MEC scores (p<0.01, OR 1.204, 95% CI 1.046-1.386) and Tinetti gait scale scores (p<0.01, OR 1.433, 95% CI 1.013-2.027), and fewer chronic drug prescriptions (p<0.001, OR 0.768, 95% CI 0.655-0.899). In conclusion, more than half of the individuals continued to age successfully. In subjects aged 87 years, the factors associated with continued successful aging were longer schooling, better cognition scores, lower risk of falls, and fewer chronic drug prescriptions at baseline evaluation.

    This study examines the associations between age at first substance use treatment entry and trajectory of outcomes over 11 years. We found significant differences in individual and treatment characteristics between adult intakes first treated during young adulthood (25 years or younger) and those first treated at an older age. Compared to their first treated older age counterparts matched on demographics and dependence type, those who entered first treatment during young adulthood had on average an earlier onset for substance use but a shorter duration between first substance use and first treatment entry; they also had worse alcohol and other drug outcomes 11 years post treatment entry. While subsequent substance use treatment and 12-step meeting attendance are important for both age groups in maintaining positive outcomes, relationships varied by age group. Findings underline the importance of different continuing care management strategies for those entering first treatment at different developmental stages. PMID:24462221

    We studied prospectively the midlife handgrip strength, living habits, and parents' longevity as predictors of length of life up to becoming a centenarian. The participants were 2,239 men from the Honolulu Heart Program/Honolulu-Asia Aging Study who were born before the end of June 1909 and who took part in baseline physical assessment in 1965-1968, when they were 56-68 years old. Deaths were followed until the end of June 2009 for 44 years with complete ascertainment. Longevity was categorized as centenarian (≥100 years, n = 47), nonagenarian (90-99 years, n = 545), octogenarian (80-89 years, n = 847), and ≤79 years (n = 801, reference). The average survival after baseline was 20.8 years (SD = 9.62). Compared with people who died at the age of ≤79 years, centenarians belonged 2.5 times (odds ratio (OR) = 2.52, 95% confidence interval (CI) = 1.23-5.10) more often to the highest third of grip strength in midlife, were never smokers (OR = 5.75 95% CI = 3.06-10.80), had participated in physical activity outside work (OR = 1.13 per daily hour, 95% CI = 1.02-1.25), and had a long-lived mother (≥80 vs. ≤60 years, OR = 2.3, 95% CI = 1.06-5.01). Associations for nonagenarians and octogenarians were parallel, but weaker. Multivariate modeling showed that mother's longevity and offspring's grip strength operated through the same or overlapping pathway to longevity. High midlife grip strength and long-lived mother may indicate resilience to aging, which, combined with healthy lifestyle, increases the probability of extreme longevity.

    Lutein is a carotenoid with strong antioxidant properties. Previous studies in adults suggest a beneficial role of lutein on cardiometabolic health. However, it is unknown whether this relation also exists in children; therefore, we aimed to assess the relation between lutein intake at 13 months of age and cardiometabolic outcomes at the age of 6 years. We included 2044 Dutch children participating in a population-based prospective cohort study. Diet was measured at 13 months of age with an FFQ. Lutein intake was standardised for energy and β-carotene intake. Blood pressure, anthropometrics, serum lipids and insulin were measured at the age of 6 years. Dual-energy X-ray absorptiometry was performed to measure total and regional fat and lean mass. A continuous cardiometabolic risk factor score was created, including the components body fat percentage, blood pressure, insulin, HDL-cholesterol and TAG. Age- and sex-specific standard deviation scores were created for all outcomes. Multivariable linear regression was performed, including socio-demographic and lifestyle variables. Median (energy-standardised) lutein intake was 1317 mcg/d (95% range 87, 6069 mcg/d). There were no consistent associations between lutein intake at 13 months and anthropometrics and body composition measures at 6 years of age. In addition, lutein intake was not associated with a continuous cardiometabolic risk factor score, nor was it associated with any of the individual components of the cardiometabolic risk factor score. Results from this large population-based prospective cohort study do not support the hypothesis that lutein intake early in life has a beneficial role for later cardiometabolic health.

    2008-01-01

    This study assessed the relationship between girls’ weight status and self-concept and examined peer teasing and parent criticism as potential mediators of this relationship. Data were collected for 182 girls and their parents when the girls were 5 and 7 years old. At each age, girls’ body mass index, self-concept, peer weight-related teasing (child report), and parents’ criticism of girls’ weight status (spouse report) were assessed. At ages 5 and 7, girls who were more overweight reported lower self-concept. Peer teasing and parent criticism mediated the relationship between weight status and self-concept at age 7, but not at age 5. In addition, the duration and timing of parent criticism across ages 5 and 7 mediated the association between girls’ weight status at age 5 and perceived peer acceptance at age 7. PMID:12220051

    This observer-blind study compared the prophylactic human papillomavirus (HPV) vaccines, Cervarix (GlaxoSmithKline) and Gardasil (Merck), by assessing immunogenicity and safety through one month after completion of the three-dose vaccination course. Women (n = 1106) were stratified by age (18-26, 27-35, 36-45 years) and randomized (1:1) to receive Cervarix (Months 0, 1, 6) or Gardasil (Months 0, 2, 6). At Month 7 after first vaccination, all women in the according-to-protocol cohort who were seronegative/DNA negative before vaccination for the HPV type analyzed had seroconverted for HPV-16 and HPV-18 serum neutralizing antibodies, as measured by pseudovirion-based neutralization assay (PBNA), except for two women aged 27-35 years in the Gardasil group who did not seroconvert for HPV-18 (98%). Geometric mean titers of serum neutralizing antibodies ranged from 2.3-4.8-fold higher for HPV-16 and 6.8-9.1-fold higher for HPV-18 after vaccination with Cervarix compared with Gardasil, across all age strata. In the total vaccinated cohort (all women who received at least one vaccine dose, regardless of their serological and DNA status prior to vaccination), Cervarix induced significantly higher serum neutralizing antibody titers in all age strata (p < 0.0001). Positivity rates for anti-HPV-16 and -18 neutralizing antibodies in cervicovaginal secretions and circulating HPV-16 and -18 specific memory B-cell frequencies were also higher after vaccination with Cervarix compared with Gardasil. Both vaccines were generally well tolerated. The incidence of unsolicited adverse events was comparable between vaccinated groups. The incidence of solicited symptoms was generally higher after Cervarix, injection site reactions being most common. However, compliance rates with the three-dose schedules were similarly high (>or= 84%) for both vaccines. Although the importance of differences in magnitude of immune response between these vaccines is unknown, they may represent determinants

  17. Cervical cancer screening among women aged 18-30 years - United States, 2000-2010.

    PubMed

    2013-01-01

    Screening women for cervical cancer can save lives. However, among young women, cervical cancer is relatively rare, and too-frequent screening can lead to high costs and adverse events associated with overtreatment. Before 2012, cervical cancer screening guidelines of the American College of Obstetricians and Gynecologists (ACOG), American Cancer Society (ACS), and U.S. Preventive Services Task Force (USPSTF) differed on age to start and how often to get screened for cervical cancer. In 2012, however, all three organizations recommended that 1) screening by Papanicolau (Pap) test should not be used for women aged <21 years, regardless of initiation of sexual activity, and 2) a screening interval of 3 years should be maintained for women aged 21-30 years. ACS and ACOG explicitly recommend against yearly screening. To assess trends in Pap testing before the new guidelines were introduced, CDC analyzed 2000-2010 data from the Behavioral Risk Factor Surveillance System (BRFSS) for women aged 18-30 years. CDC found that, among women aged 18-21 years, the percentage reporting never having been screened increased from 26.3% in 2000 to 47.5% in 2010, and the proportion reporting having had a Pap test in the past 12 months decreased from 65.0% to 41.5%. Among those aged 22-30 years, the proportion reporting having had a Pap test within the preceding 12 months decreased from 78.1% to 67.0%. These findings showed that Pap testing practices for young women have been moving toward the latest guidelines. However, the data also showed a concerning trend: among women aged 22-30 years, who should be screened every 3 years, the proportion who reported never having had a Pap test increased from 6.6% to 9.0%. More effort is needed to promote acceptance of the latest evidence-based recommendations so that all women receive the maximal benefits of cervical cancer screening.

    Poor gait is an important risk factor for falls and associated with higher morbidity and mortality. It is well established that older age is associated with worse gait, but it remains unclear at what age this association is first seen. Moreover, previous studies focused mainly on normal walking, but gait also encompasses turning and tandem walking. In a large study of community-dwelling middle-aged and elderly persons we investigated the association of age with gait, focusing on normal walking, turning and tandem walking. In 1500 persons aged 50 years and over, we measured gait using an electronic walkway. Participants performed normal walks, turning and a tandem walk. With principal components analysis of 30 variables we summarized gait into five known gait factors: Rhythm, Variability, Phases, Pace and Base of Support; and uncovered two novel gait factors: Tandem and Turning. The strongest associations with age were found for Variability (difference in Z-score -0.29 per 10 years increase (95% confidence interval: -0.34; -0.24)), Phases (-0.31 per 10 years (-0.36; -0.27)) and Tandem (-0.25 per 10 years (-0.30; -0.20)). Additionally, these factors already showed association with the youngest age groups, from 55 to 60 years of age and older. Our study shows that Variability, Phases and Tandem have the strongest association with age and are the earliest to demonstrate a poorer gait pattern with higher age. Future research should further investigate how these gait factors relate with gait-related diseases in their earliest stages.

  19. Effects of aging in Masters swimmers: 40-year review and suggestions for optimal health benefits.

    2010-04-07

    The Masters Swimming Program is over 40 years old and has achieved international status, with thousands of participants competing in five-year age categories between 18 and 99. Early studies of Masters swimmers by age groups found an increase in times for most events of about 1% per year, and later studies showed a significant correlation with the age-associated decline in maximal oxygen uptake. As larger sample sizes have become available, the age-related decline in performance among national champion Masters swimmers, both men and women, and for both short and longer swims, has been shown to be linear at about 0.6% per year up to age 70. Beyond age 70, the age-related decline accelerates exponentially for both men and women, with considerably more variability than in younger age groups. Several factors may be related to the accelerated performance decline beyond the of age 70, including accelerated physiological aging, chronic physical disabilities, acute illnesses requiring relatively lengthy recovery, effects of multiple medications, and social issues such as transportation problems, all of which can lead to increasing difficulty in maintaining a regular workout schedule. Masters Swimming is a "user-friendly" aerobic sport, imposing little excess strain, and thus is particularly suitable for the elderly. Masters coaches are gaining increasing experience with the over-70 age groups, tailoring workouts to accommodate their need for longer warm-up periods, longer rest periods between swimming sets, less overall distance, less emphasis on "breath control", and more time between workouts. With these accommodations, the motivation of elderly Masters swimmers to compete remains strong, and their ranks should continue to increase.

  20. Is prosthodontic treatment age-dependent in patients 60 years and older in Public Dental Services?

    Prosthodontic treatment is a common procedure for the elderly as tooth loss is a reality in old age. Dentists take care of increasingly older patients with physiological age manifesting as cognitive impairment, frailty or multiple chronic diseases or who have side effects of medicines. We evaluated how patients' age affects prosthodontic treatment choice and whether we could identify the age when a change in practice occurs. In addition, we determined how common the treatment method of fixed prostheses is among patients aged 60 years or over in Public Dental Services (PDS) and how common rehabilitation of dentition with new dentures is compared with repair of existing dentures. Our data cover all patients aged 60 years and older (n = 130,060) treated in Helsinki PDS in 2007-2012. Data were aggregated into seven groups: 60-64, 65-69, 70-74, 75-79, 80-84, 85-89, and 90 years and over. During the 6-year period, the mean annual number of the population was about 114,000 and the mean annual number of patients treated with prosthodontics 1700. Prosthodontic treatment choices (repair, removable prosthodontics, fixed prostheses, fibre-reinforced composite fixed prostheses) vary by age; the older the patient, the rarer fixed or fibre-reinforced composite fixed prostheses and removable prostheses and the more frequent repairs (P < 0.001). Denture repair was virtually the only treatment that patients over 90 years received. Based on our results, the age at which prosthodontic treatment practices in PDS change is around 70 years. Beyond this age, fixed prosthodontic treatment modalities are very rare and repairs are more common.

    Physical activity can help delay, prevent, or manage many of the chronic diseases for which adults aged ≥50 years are at risk (1-3). These diseases can impact the length and quality of life, as well as the long-term ability to live independently.* All adults aged ≥50 years, with or without chronic disease, gain health benefits by avoiding inactivity (2,3). To examine the prevalence of inactivity by selected demographic characteristics and chronic disease status in mid-life and older adults, CDC analyzed data on adults aged ≥50 years from the 2014 Behavioral Risk Factor Surveillance System (BRFSS). Overall, 27.5% of adults aged ≥50 years reported no physical activity outside of work during the past month. Inactivity prevalence significantly increased with increasing age and was 25.4% among adults aged 50-64 years, 26.9% among those aged 65-74 years, and 35.3% among those aged ≥75 years. Inactivity prevalence was significantly higher among women than men, among Hispanics and non-Hispanic blacks than among non-Hispanic whites, and among adults who reported ever having one or more of seven selected chronic diseases than among those not reporting one. Inactivity prevalence significantly increased with decreasing levels of education and increasing body mass index. To help adults with and without chronic disease start or maintain an active lifestyle, communities can implement evidence-based strategies, such as creating or enhancing access to places for physical activity, designing communities and streets to encourage physical activity, and offering programs that address specific barriers to physical activity.

    A computer-aided-diagnosis (CAD) method has been previously developed based on features extracted from phalangeal regions of interest (ROI) in a digital hand atlas, which can assess bone age of children from ages 7 to 18 accurately. Therefore, in order to assess the bone age of children in younger ages, the inclusion of carpal bones is necessary. In this paper, we developed and implemented a knowledge-based method for fully automatic carpal bone segmentation and morphological feature analysis. Fuzzy classification was then used to assess the bone age based on the selected features. Last year, we presented carpal bone segmentation algorithm. This year, research works on procedures after carpal bone segmentation including carpal bone identification, feature analysis and fuzzy system for bone age assessment is presented. This method has been successfully applied on all cases in which carpal bones have not overlapped. CAD results of total about 205 cases from the digital hand atlas were evaluated against subject chronological age as well as readings of two radiologists. It was found that the carpal ROI provides reliable information in determining the bone age for young children from newborn to 7-year-old.

    We examined simultaneously the influence of age as well as both current and historical habitual physical activity (PA) on aerobic (physical working capacity - PWC) and anaerobic (Pmax) power in 354 men aged 20.2-87.6 yrs. All the participants performed the graded aerobic exercise test and 8-second explosive power tests on a bicycle ergometer. Current leisure time physical activity (LTPA) and lifetime historical LTPA were assessed. The decline in Pmax/kg (10.3% per decade) was higher than in PWC/kg (7.5% per decade). Correlation coefficients for current LTPA and aerobic indices were higher than for current LTPA and anaerobic indices. In a multiple stepwise regression, current LTPA had the main effect on PWC/kg, whereas age had the main effect on Pmax/kg. Aerobic power was related to all measures of historical PA questionnaire, while anaerobic power - only to those historical measures which pertained to adolescence and younger years of adulthood. We conclude that the age-associated decline in anaerobic power is steeper than that of aerobic power. Habitual endurance-type LTPA increases aerobic but not anaerobic fitness throughout the adult lifespan. Anaerobic fitness indices are higher in young active vs sedentary men but this difference is not discernible as early as in the middle age.

    The present study investigated the association of the relative age effect, a biased distribution of birth dates, with a high school versus university background in Japanese professional soccer and baseball players. The number of athletes born in the first quarter (April-June) was larger than the number born in the fourth quarter (January-March) for both soccer and baseball; however, the magnitude of the relative age effect differed with years in school. The skew of birth dates was stronger among players who only graduated high school than those who graduated university or college. This phenomenon was confirmed in both baseball and soccer players. The findings suggest relative age effects in professional sports to be related to years of age and years in school. PMID:23033753

    Successful brain aging in the oldest old (≥90 years) is underexplored. This study examined cross-sectional brain morphological differences from 8th to 11th decades of life in nondemented individuals by high-resolution magnetic resonance imaging. Two hundred seventy-seven nondemented community-dwelling participants (71-103 years) from Sydney Memory and Ageing Study and Sydney Centenarian Study comprised the sample, including a subsample of 160 cognitively high-functioning elders. Relationships between age and magnetic resonance imaging-derived measurements were studied using general linear models; and structural profiles of the ≥90 years were delineated. In full sample and the subsample, significant linear negative relationship of gray matter with age was found, with the greatest age effects in the medial temporal lobe and parietal and occipital cortices. This pattern was further confirmed by comparing directly the ≥90 years to the 71-89 years groups. Significant quadratic age effects on total white matter and white matter hyperintensities were observed. Our study demonstrated heterogeneous differences across brain regions between the oldest old and young old, with an emphasis on hippocampus, temporoposterior cortex, and white matter hyperintensities.

    Previous studies have repeatedly shown verbal intelligence deficits in adolescent antisocial individuals, but it is not known whether these deficits are in place prior to kindergarten or, alternatively, whether they are acquired throughout childhood. This study assesses whether cognitive deficits occur as early as age 3 years and whether they are specific to persistently antisocial individuals. Verbal and spatial abilities were assessed at ages 3 and 11 years in 330 male and female children, while antisocial behavior was assessed at ages 8 and 17 years. Persistently antisocial individuals (N = 47) had spatial deficits in the absence of verbal deficits at age 3 years compared to comparisons (N = 133), and also spatial and verbal deficits at age 11 years. Age 3 spatial deficits were independent of social adversity, early hyperactivity, poor test motivation, poor test comprehension, and social discomfort during testing, and they were found in females as well as males. Findings suggest that early spatial deficits contribute to persistent antisocial behavior whereas verbal deficits are developmentally acquired. An early-starter model is proposed whereby early spatial impairments interfere with early bonding and attachment, reflect disrupted right hemisphere affect regulation and expression, and predispose to later persistent antisocial behavior.

    Background Mortality in children under five years has been widely studied, whereas mortality at 5–9 years has received little attention. Using unique data from national registers in three Nordic countries, we aimed to characterize mortality directionality in children aged 0 to 9 years. Methods and Findings The cohort study included all children born in Denmark from 1973 to 2008 (n = 2,433,758), Sweden from 1973 to 2006 (n = 3,400,212), and a random sample of 89.3% of children born in Finland from 1987 to 2007 (n = 1,272,083). Children were followed from 0 to 9 years, and cumulative mortality and mortality rates were compared by age, gender, cause of death, and calendar periods. Among the 7,105,962 children, there were 48,299 deaths during study period. From 1981–1985 to 2001–2005, all-cause mortality rates were reduced by between 34% and 62% at different ages. Overall mortality rate ratio between boys and girls decreased from 1.25 to 1.21 with the most prominent reduction in children aged 5–9 years (from 1.59 to 1.19). Neoplasms, diseases of the nervous system and transport accidents were the most frequent cause of death after the first year of life. These three leading causes of death declined by 42% (from 6.2 to 3.6 per 100,000 person years), 43% (from 3.7 to 2.1) and 62% (from 3.9 to 1.5) in boys, and 25% (from 4.1 to 3.1 per 100000 person years), 42% (from 3.4 to 1.9) and 63% (from 3.0 to 1.1) in girls, respectively. Mortality from neoplasms was the highest in each age except infants when comparing cause-specific mortality, and half of deaths from diseases of the nervous system occurred in infancy. Mortality rate due to transport accidents increased with age and was highest in boys aged 5–9 years. Conclusions Mortality rate in children aged 0–9 years has been decreasing with diminished difference between genders over the past decades. Our results suggest the importance of further research on mortality by causes of neoplasms, and causes of transport

    Scholars argue about whether age stereotypes (beliefs about old people) are becoming more negative or positive over time. No previous study has systematically tested the trend of age stereotypes over more than 20 years, due to lack of suitable data. Our aim was to fill this gap by investigating whether age stereotypes have changed over the last two centuries and, if so, what may be associated with this change. We hypothesized that age stereotypes have increased in negativity due, in part, to the increasing medicalization of aging. This study applied computational linguistics to the recently compiled Corpus of Historical American English (COHA), a database of 400 million words that includes a range of printed sources from 1810 to 2009. After generating a comprehensive list of synonyms for the term elderly for these years from two historical thesauri, we identified 100 collocates (words that co-occurred most frequently with these synonyms) for each of the 20 decades. Inclusion criteria for the collocates were: (1) appeared within four words of the elderly synonym, (2) referred to an old person, and (3) had a stronger association with the elderly synonym than other words appearing in the database for that decade. This yielded 13,100 collocates that were rated for negativity and medicalization. We found that age stereotypes have become more negative in a linear way over 200 years. In 1880, age stereotypes switched from being positive to being negative. In addition, support was found for two potential explanations. Medicalization of aging and the growing proportion of the population over the age of 65 were both significantly associated with the increase in negative age stereotypes. The upward trajectory of age-stereotype negativity makes a case for remedial action on a societal level.

    This study examined the outcome of elective shoulder arthroplasty for glenohumeral osteoarthritis or rotator cuff arthropathy in patients aged older than 90 years. The study included 7 shoulders in 6 patients with an average age of 93 years 5 months, (range, 91 years 0 months to 97 years 4 months). Average follow-up was 2.2 years, (range, 1-4 years). Preoperative range of motion, Simple Shoulder Test (SST) scores, and Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36) scores were obtained and compared with postoperative values at 3 and 6 months and yearly thereafter. Average forward elevation improved from 87 degrees to 137 degrees (P < .00001), and external rotation to the side improved from 0 degrees to 50 degrees (P < .0001). The SST scores improved from a preoperative average of 2.0 to 6.1 at 3 months (P < .0001), 6.9 at 6 months (P < .0001), 8.0 at 1 year (P < .00001), and 7.4 at 2 years (P < .0001). Significant improvements occurred in 6 of 8 SF-36 domains: Mental Health (P < .05), Vitality (P < .01), Role limitations due to emotional problems (P < .05), Social Function (P < .001), Role limitations due to physical health (P < .001), and Comfort (P < .00001). No patient had worse pain or function postoperatively. These data suggest that elective shoulder arthroplasty can be performed in patients 90 years of age and older, providing excellent pain relief, improved functional outcome, and enhanced general health status.

  17. Age inclusive services or separate old age and working age services? A historical analysis from the formative years of old age psychiatry c.1940-1989.

    2015-04-01

    The Equality Act 2010 made it unlawful to discriminate in the provision of services on the grounds of age. This legislation is open to interpretation, but it is affecting the way older people's services are defined and provided. Historical evidence indicates that, since the 1940s, apart from psychiatrists working in dedicated old age services, most were unenthusiastic about working with mentally unwell older people and unsupportive of those who chose to do so. A historical analysis might shed light on current dilemmas about 'all age' or 'old age' services and inform decision-making on future mental health services.

    Object Patients with moyamoya who are younger than 2 years of age represent a therapeutic challenge because of their frequent neurological instability and concomitant anesthetic risks. The authors report their experience with pial synangiosis revascularization in this population. Methods The authors reviewed the clinical and radiographic records of all patients with moyamoya in a consecutive series of patients under 2 years of age, who underwent cerebral revascularization surgery using pial synangiosis at a single institution. Results During a 12-year period (1994-2005), 34 procedures (bilateral in 15 patients, unilateral in 4) were performed in 19 patients younger than 2 years (out of a total of 456 procedures in 240 patients). Eighteen of these patients presented with either stroke or transient ischemic attack. The average age of the 19 patients at first surgery was 1.4 years (range 6 months-1.9 years). Unanticipated staged operations occurred in 3 patients, due to persistent electroencephalographic changes during the initial surgery in 2 cases and due to brain swelling during the procedure requiring ventriculostomy in the other. There were 2 perioperative strokes; both patients had postoperative seizures but made clinical recoveries. The average follow-up was 7 years (range 1-14 years). Long term, at follow-up, 13 patients (68%) were clinically independent for their age, with 8 (42%) having no significant deficit. Late complications included subdural hygroma evacuation (1), additional revascularization procedures performed years later for frontal lobe ischemia (2), late infarction (1), and asymptomatic ischemic change on routine follow-up MRI studies (1). All patients who had both pre- and postoperative angiography demonstrated progression of disease. Conclusions Despite the challenges inherent to this population, the majority of children with moyamoya under the age of 2 years have a good long-term prognosis. The data from this study support the use of pial

    This paper proposes the use of two-factor models (age-period and age-cohort models) to estimate age, period, and cohort effects on pulmonary function by using the data collected in a 24-year longitudinal study in the Netherlands from 1965 to 1990. The analysis included 18,363 pulmonary function measurements on 6,148 subjects aged 20-54 years at the initial visit. The subjects were grouped into four birth cohorts (before 1923, 1923-1934, 1935-1946, and after 1946) and four survey periods (1965-1972, 1973-1978, 1979-1984, and 1985-1990). In the age-cohort model, the decrement in forced expiratory volume in 1 second (FEV1) associated with a yearly increase in age was 28.3 +/- 3.7 ml/year for a man 176 cm tall and 16.0 +/- 1.9 ml/year for a woman 163 cm tall. The estimated acceleration of decline with aging was significant for both men (beta = -0.212; standard error = 0.079 ml) and women (beta = -0.346; standard error = 0.058 ml). Compared with that of the cohort born before 1923, the average level of FEV1 was estimated to increase by 156, 277, and 379 ml, respectively, for the three younger cohorts in men (p = 0.01) and by 133, 213, and 328 ml for the three younger cohorts in women (p < 0.01). In the age-period model, the estimated linear age effect on FEV1 was 36.2 +/- 4.2 ml/year for a man and 30.5 +/- 2.3 ml/year for a woman. The age quadratic term was significant for women, but not for men. Average FEV1 was estimated to be increased by 141, 169, and 250 ml, respectively, for the periods 1973-1978, 1979-1984, and 1985-1990 in men and by 131, 138, and 219 ml in women. These period effects were significant for both men and women. In summary, this study applied the two-factor models to estimate cross-sectional and longitudinal effects of aging on FEV1 and demonstrated significant period and cohort effects, which could be attributed in part to changes in air pollutants, respiratory infections, vaccinations, types of cigarettes, diet, and lifestyles over time.

    Purpose. Following the demonstrated efficacy and safety of eribulin mesylate in heavily pretreated patients with metastatic breast cancer, an exploratory analysis was performed to investigate the effect of age in these patients. Methods. Data were pooled from two single-arm phase II studies and one open-label randomized phase III study in which patients received eribulin mesylate at 1.4 mg/m2 as 2- to 5-minute intravenous infusions on days 1 and 8 of a 21-day cycle. The effect of age on median overall survival (OS), progression-free survival (PFS), overall response rate (ORR), clinical benefit rate (CBR), and incidence of adverse events (AEs) was calculated for four age groups (<50 years, 50–59 years, 60–69 years, ≥70 years). Results. Overall, 827 patients were included in the analysis (<50 years, n = 253; 50–59 years, n = 289; 60–69 years, n = 206; ≥70 years, n = 79). Age had no significant impact on OS (11.8 months, 12.3 months, 11.7 months, and 12.5 months, respectively; p = .82), PFS (3.5 months, 2.9 months, 3.8 months, and 4.0 months, respectively; p = .42), ORR (12.7%, 12.5%, 6.3%, and 10.1%, respectively), or CBR (20.2%, 20.8%, 20.4%, and 21.5%, respectively). Although some AEs had higher incidence in either the youngest or the oldest subgroup, there was no overall effect of age on the incidence of AEs (including neuropathy, neutropenia, and leukopenia). Conclusion. Eribulin monotherapy in these selected older patients with good baseline performance status led to OS, PFS, ORR, CBR, and tolerability similar to those of younger patients with metastatic breast cancer. The benefits and risks of eribulin appear to be similar across age groups. PMID:24682463

    This study characterized guaifenesin pharmacokinetics in children aged 2 to 17 years (n = 40) who received a single oral dose of guaifenesin (age-based doses of 100-400 mg) 2 hours after breakfast. Plasma samples were obtained before and for 8 hours after dosing and analyzed for guaifenesin using liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters were estimated using noncompartmental methods, relationships with age were assessed using linear regression, and dose proportionality was assessed on 95% confidence intervals. Based on the upper dose recommended in the monograph (for both children and adolescents), area under the curve from time zero to infinity and maximum plasma concentration both increased with age. However, when comparing the upper dose for children aged 2 to 11 years with the lower dose for adolescents aged 12 to 17 years, similar systemic exposure was observed. As expected due to increasing body size, oral clearance (CLo ) and terminal volume of distribution (Vz /F) increased with age. Due to a larger increase in Vz /F than CLo , an increase in terminal exponential half-life was also observed. Allometric scaling indicated no maturation-related changes in CLo and Vz /F.

    This is a descriptive cross-sectional study of the population base conducted in the town of Colombo in the state of Paraná. The objectives were to identify the prevalence of food insecurity in families that are beneficiaries of the Bolsa Família Program and the factors related to this condition, and describe the nutritional status of children under five years of age. Analyses of association were performed using Fisher's exact test. The sample included 442 families, of which 168 have children under five years of age. The Brazilian Food Insecurity Scale was applied to evaluate food insecurity and the nutritional status of the 199 children evaluated was determined by the height-for-age, weight-for-age and body mass-for-age indices in accordance with the WHO reference values for 2006. The prevalence of food insecurity was 81.6%. Overweight and stunting among children coexisted. Food insecurity was found to be associated with the height-for-age index among children under two years of age. The per capita income and food deficits influenced the situation of food insecurity significantly.

    This study followed a cohort of 46 school-age children adopted from Eastern Europe who were originally studied by Glennen and Masters up through age 2 or 3. Five years later, the children were 6 to 9 years of age. Data on their school-age abilities were collected through surveys of parents and teachers. Parents indicated that 17.4% of the children were receiving classroom accommodations or special education programs and 54.5% had one or more diagnoses. The most common diagnosis was attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD), occurring in 25% of the children, primarily boys. Learning disability and speech language impairment were each noted in 11.4% of the children. Language and Social Skill profiles on the Children's Communication Checklist-2 and Social Skills Rating Scale (SSRS) indicated that structural and meaning-based language abilities were areas of strength. Measures of pragmatic use of language (i.e., Use of Context, Social Relations, Nonverbal Communication) were relative weaknesses. Behavior profiles on the SSRS indicated higher than average levels of hyperactivity. The profile of Language and Social Skills strengths and weaknesses was similar to patterns observed in children with ADD/ADHD. Age of adoption was not predictive of school-age outcomes on these measures, but the children's expressive vocabulary when they were 2 to 3 years of age predicted SSRS outcomes for Social Skills and Problem Behaviors.

  4. Homicide rates among persons aged 10-24 years - United States, 1981-2010.

    2013-07-12

    Homicide disproportionately affects persons aged 10-24 years in the United States and consistently ranks in the top three leading causes of death in this age group, resulting in approximately 4,800 deaths and an estimated $9 billion in lost productivity and medical costs in 2010. To investigate trends in homicide among persons aged 10-24 years for the period 1981-2010, CDC analyzed National Vital Statistics System data on deaths caused by homicide of persons in this age group and examined trends by sex, age, race/ethnicity, and mechanism of injury. This report describes the results of that analysis, which indicated that homicide rates varied substantially during the study period, with a sharp rise from 1985 to 1993 followed by a decline that has slowed since 1999. During the period 2000-2010, rates declined for all groups, although the decline was significantly slower for males compared with females and for blacks compared with Hispanics and persons of other racial/ethnic groups. By mechanism of injury, the decline for firearm homicides from 2000 to 2010 was significantly slower than for nonfirearm homicides. The homicide rate among persons aged 10-24 years in 2010 was 7.5 per 100,000, the lowest in the 30-year study period. Primary prevention strategies remain critical, particularly among groups at increased risk for homicide.

    Objectives: To establish reference values for fatty acids (FA) especially for n-3 and n-6 long-chain polyunsaturated FAs (LC PUFA) in whole-blood samples from apparently healthy 3–8-year-old European children. The whole-blood FA composition was analysed and the age- and sex-specific distribution of FA was determined. Design and subjects: Blood samples for FA analysis were taken from 2661 children of the IDEFICS (identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study cohort. Children with obesity (n=454) and other diseases that are known to alter the FA composition (n=450) were excluded leaving 1653 participants in the reference population. Measurements: The FA composition of whole blood was analysed from blood drops by a rapid, validated gas chromatographic method. Results: Pearson correlation coefficients showed an age-dependent increase of C18:2n-6 and a decrease of C18:1n-9 in a subsample of normal weight boys and girls. Other significant correlations with age were weak and only seen either in boys or in girls, whereas most of the FA did not show any age dependence. For age-dependent n-3 and n-6 PUFA as well as for other FA that are correlated with age (16:0, C18:0 and C18:1n-9) percentiles analysed with the general additive model for location scale and shape are presented. A higher median in boys than in girls was observed for C20:3n-6, C20:4n-6 and C22:4n-6. Conclusions: Given the reported associations between FA status and health-related outcome, the provision of FA reference ranges may be useful for the interpretation of the FA status of children in epidemiological and clinical studies.

    2013-01-01

    The aim of the study was to investigate the development of a rhythmical skill of children aged from 5 to 12 years old. Five age groups (5–6, 7–8, 9–10, 11–12, and young adults) performed a virtual ball bouncing task (16 forty-second long test trials). Task performances, racket oscillation, ball-racket impacts as well as the ball-racket coupling were analysed. The results showed a change in both performance and behaviour at the age of 7 years old. Before this age, children exhibited restricted perceptual-motor coordination with a high frequency of racket oscillation and a poor level of performance. After the age of 7, cycle-to-cycle adaptive coordination based on visual information was progressively acquired leading to increasing performance levels with age. Overall these results revealed a rapid change in capability to perform the ball bouncing task across age with a late emergence of the required coordination and significant change in the coordination at the age of 7.

    Objective To determine the association of urbanicity, defined as living in an urban area, with cognitive development at five years of age in preterm children who were free of any disabilities or neurodevelopmental delays. Design Prospective population-based cohort. Setting French regional Loire Infant Follow-up Team (LIFT) network. Participants Included in the study were 1738 surviving infants born between March 2003 and December 2008 before 35 weeks of gestational age. At two years of age, the children were free of any disabilities and neurodevelopmental delays and were living in the Pays de la Loire region from their birth to five years of age. Main Outcome Measures The cognitive development at five years of age was evaluated with the Global School Adaptation score (GSA). The urbanicity of the residence for each child was classified into three groups: urban, quasi-rural, and rural area. Results Quantile regression approaches were used to identify a significant association between urbanicity and the GSA score at five years of age (adjusting for child and family characteristics). We found that the negative impact of urbanicity on the GSA score was more important for the lower quantile of the GSA scores. Conclusions Urbanicity was significantly associated with cognitive neurodevelopment at five years of age in preterm children born before 35 weeks of gestation. Complementary results additionally suggest that this relation could be mediated at the residence level by a high socioeconomic deprivation level. If these results are confirmed, more personalized follow-ups could be developed for preterm children. Further studies are needed to finely identify the contextual characteristics of urbanicity that underlie this association. PMID:26161862

    Background A trial involving adults 50 years of age or older (ZOE-50) showed that the herpes zoster subunit vaccine (HZ/su) containing recombinant varicella-zoster virus glycoprotein E and the AS01B adjuvant system was associated with a risk of herpes zoster that was 97.2% lower than that associated with placebo. A second trial was performed concurrently at the same sites and examined the safety and efficacy of HZ/su in adults 70 years of age or older (ZOE-70). Methods This randomized, placebo-controlled, phase 3 trial was conducted in 18 countries and involved adults 70 years of age or older. Participants received two doses of HZ/su or placebo (assigned in a 1:1 ratio) administered intramuscularly 2 months apart. Vaccine efficacy against herpes zoster and postherpetic neuralgia was assessed in participants from ZOE-70 and in participants pooled from ZOE-70 and ZOE-50. Results In ZOE-70, 13,900 participants who could be evaluated (mean age, 75.6 years) received either HZ/su (6950 participants) or placebo (6950 participants). During a mean follow-up period of 3.7 years, herpes zoster occurred in 23 HZ/su recipients and in 223 placebo recipients (0.9 vs. 9.2 per 1000 person-years). Vaccine efficacy against herpes zoster was 89.8% (95% confidence interval [CI], 84.2 to 93.7; P<0.001) and was similar in participants 70 to 79 years of age (90.0%) and participants 80 years of age or older (89.1%). In pooled analyses of data from participants 70 years of age or older in ZOE-50 and ZOE-70 (16,596 participants), vaccine efficacy against herpes zoster was 91.3% (95% CI, 86.8 to 94.5; P<0.001), and vaccine efficacy against postherpetic neuralgia was 88.8% (95% CI, 68.7 to 97.1; P<0.001). Solicited reports of injection-site and systemic reactions within 7 days after injection were more frequent among HZ/su recipients than among placebo recipients (79.0% vs. 29.5%).

    We compile a unique 13-year record of groundwater age for 11 springs in Sagehen basin, a watershed in the Sierra Nevada Mountains of California, USA. Chlorofluorocarbon (CFC), sulfur hexafluoride (SF6), and tritium (3H) data collected in prior studies from 1997 to 2003 are re-interpreted and combined with new data collected in 2009 and 2010. The age record is analyzed to explore the potential value of groundwater age monitoring for (1) providing additional constraints on the age distribution in mixed-age samples, and (2) identifying temporal changes in groundwater recharge. Motivation for this study is provided by a lack of knowledge of how groundwater recharge and discharge (stream baseflow) in mountain watersheds might respond to climate change, and a resulting need to better understand mountain aquifer residence times, storage, and recharge. Piston-flow ages for the springs generally range from 10 to 50 yr. The plausibility of different age mixing models is tested by comparing observed temporal variations in age with those simulated using simple numerical models, and by examining plots comparing the concentrations of different age tracers. We find that most spring waters are best characterized by a bimodal mixing model consisting of a new (<1 yr old) fraction and a fraction that is older, but still modern (recharged after 1950). Identification of this mixing model would not have been possible without data from multiple age tracers and data from multiple years. Computed mean ages vary substantially (often by 3-7 yr) between sampling events for most springs, including those with ages of 20-50 yr. Mean age variations are likely controlled by variations in the magnitude of the new fraction, which is positively correlated with annual snowpack water content. Most springs show overall upward trends in mean age for the sampling period, consistent with decreasing recharge rates in response to diminishing snowpack. Groundwater age monitoring appears to be a potentially

    In the Pacific Region, some adult populations have shown a steady rise in overweight and obesity across the 1970s and into the 1990s. While younger adults have been shown to have lower body mass index (BMI) than older ones in both the least and most modernised Samoan populations, among intermediately modernised Samoan populations, BMI has been found to be higher in younger adults than in older ones. A survey in the Cook Islands carried out in 1966 showed no age group differences in height, weight and BMI among adult males, but significantly higher mean weight and BMI among adult males aged 30 years and above. The present analysis gives mean height, weight, BMI and skinfolds of adult males above 30 years of age on Rarotonga in 1996, and examines whether the BMI-age group relationship now shows a similar transitional pattern to that observed on American Samoa. In addition, the 1996 values are compared with values obtained in 1986, to determine whether changes in physique have taken place across this time. In the 1996 volunteer sample of 142 male Cook Islanders, older adults are significantly shorter, lighter, with lower BMI than younger adults. Furthermore, the younger adults of the 1996 survey are significantly heavier, with greater BMI than the 1986 sample. This suggests that the adult male Rarotongan population is in an intermediate position with respect to lifestyle transition, the secular trend in body size and increasing prevalence of obesity, and that there has been a rapid increase in body fatness prevalence among younger adults.

    Background: Existing guidelines on screening children less than 5 years of age for developmental delay vary. In this systematic review, we synthesized the literature on the effectiveness and harms of screening for developmental delay in asymptomatic children aged 1-4 years. Methods: We searched MEDLINE, Embase and PsychINFO for relevant articles published to June 16, 2015. We identified studies that included children aged 1-4 years who were not at high risk of developmental delay, screened in a primary care setting. Randomized trials and controlled cohort studies were considered for benefits (cognitive, academic and functional outcomes); no restrictions on study design were imposed for the review of harms. Results: Two studies were included. One used the Ages and Stages Questionnaire II for screening and reported significantly more referrals to early intervention in the intervention groups than in the control group (relative risk [RR] 1.95, 95% confidence interval [CI] 1.49-2.54, in the intervention group with office support and RR 1.71, 95% CI 1.30-2.25, in the intervention group without office support). The time to referral was 70% shorter in the intervention group with office support (rate ratio 0.30, 95% CI 0.19-0.48) and 64% shorter in the intervention group without office support (rate ratio 0.36, 95% CI 0.23-0.59), compared with the control group. The other study used the VroegTijdige Onderkenning Ontwikkelingsstoornissen Language Screening instrument to screen children aged 15 months at enrolment for language delay. It reported no differences between groups in academic performance outcomes at age 8 years. Interpretation: The evidence on screening for developmental delay in asymptomatic children aged 1-4 years is inconclusive. Further research with longer-term outcomes is needed to inform decisions about screening and screening intervals. PMID:27226967

    This study investigated whether parenting behaviors differed between parents of 68 clinically anxious children and 106 healthy control children aged 4-12 years. The effects of parent gender, child gender and child age on parenting were explored. Mothers and fathers completed a questionnaire to assess parenting behaviors in for children hypothetically anxious situations. Results showed that parents of clinically anxious children reported more anxiety-enhancing parenting (reinforcement of dependency and punishment) as well as more positive parenting (positive reinforcement). For the clinical sample, fathers reported using more modeling/reassurance than mothers, and parents reported using more force with their 4-7-year-olds than with their 8-12-year-olds. No interaction effects were found for child gender with child anxiety status on parenting. Results indicate that for intervention, it is important to measure parenting behaviors, and to take into account father and mother differences and the age of the child. PMID:25819172

    The Bayley Scales of Infant Development were administered at 1 year of age to 54 healthy infants of adolescent mothers. Information was obtained regarding maternal cognitive and emotional maturity, child-rearing attitudes, attitudes toward the infant, and psychosocial status at one year. The average Bayley Mental Scale score was 113, and the average Bayley Motor Scale score was 105. There was a negative correlation between the Bayley Mental Scale score and maternal age and education. Bayley Motor Scale scores were predictable from a combination of maternal authoritarian attitudes, abuse potential, and infant's birth weight. Although high authoritarian attitudes in mothers have been associated with poor cognitive development at later ages, they may represent an important strength in adolescent mothers during the first year.

    Abstract This study characterized guaifenesin pharmacokinetics in children aged 2 to 17 years (n = 40) who received a single oral dose of guaifenesin (age‐based doses of 100‐400 mg) 2 hours after breakfast. Plasma samples were obtained before and for 8 hours after dosing and analyzed for guaifenesin using liquid chromatography‐tandem mass spectrometry. Pharmacokinetic parameters were estimated using noncompartmental methods, relationships with age were assessed using linear regression, and dose proportionality was assessed on 95% confidence intervals. Based on the upper dose recommended in the monograph (for both children and adolescents), area under the curve from time zero to infinity and maximum plasma concentration both increased with age. However, when comparing the upper dose for children aged 2 to 11 years with the lower dose for adolescents aged 12 to 17 years, similar systemic exposure was observed. As expected due to increasing body size, oral clearance (CLo) and terminal volume of distribution (Vz/F) increased with age. Due to a larger increase in Vz/F than CLo, an increase in terminal exponential half‐life was also observed. Allometric scaling indicated no maturation‐related changes in CLo and Vz/F. PMID:26632082

    Due to increasingly numerous international migrations, estimating the age of unaccompanied minors is becoming of enormous significance for forensic professionals who are required to deliver expert opinions. The third molar tooth is one of the few anatomical sites available for estimating the age of individuals in late adolescence. This study verifies the accuracy of Cameriere's cut-off value of the third molar index (I3M) in assessing 18 years of age. For this purpose, a sample of orthopantomographs (OPTs) of 397 living subjects aged between 13 and 22 years (192 female and 205 male) was analyzed. Age distribution gradually decreases as I3M increases in both males and females. The results show that the sensitivity of the test was 86.6%, with a 95% confidence interval of (80.8%, 91.1%), and its specificity was 95.7%, with a 95% confidence interval of (92.1%, 98%). The proportion of correctly classified individuals was 91.4%. Estimated post-test probability, p was 95.6%, with a 95% confidence interval of (92%, 98%). Hence, the probability that a subject positive on the test (i.e., I3M<0.08) was 18 years of age or older was 95.6%.

    Objective: The purpose of this study was to examine the effects of age, common life transitions, treatment, and social support on outcomes 5–9 years after alcohol and other drug (AOD) treatment intake. Method: Participants were patients from a large outpatient AOD treatment program in an integrated health plan. There were 1,951 participants interviewed at intake, of whom 1,646 (84%) completed one or more telephone follow-up interviews at 5, 7, and 9 years. Measures included AOD use based on the Addiction Severity Index; treatment; and changes in marital, employment, and health status in the years between each follow-up. We compared participants by age group (18–39, 40–54, and >55 years old at intake) and examined factors (time invariant and time varying) associated with outcomes at 5, 7, and 9 years by fitting mixed-effects logistic random intercept models. Results: Changes in marital, employment, and health status varied significantly by age. Factors associated with remission across Years 5–9 included being in the middle-aged versus younger group (p < .001); female gender (p < .001); not losing a partner to separation, divorce, or death (p < .001); not experiencing a decline in health (p = .021); having any close friends supportive of recovery (p < .001); and not having any close friends who encourage AOD use (p < .001). Additional predictors, including employment changes, varied by drug versus alcohol abstinence outcome measures. Conclusions: Negative life transitions vary by age and are associated with worse outcomes. Older age and social support are associated with long-term AOD remission and abstinence. Findings inform treatment strategies to enhance recovery across the life span. PMID:22456251

    Objectives To investigate the ability of work-related measurements, body composition, physical activity, and fitness levels to predict neck/shoulder pain (upper body pain, UBP) at the age of 52 years. Another aim was to investigate the cross-sectional relationships between UBP, work-related factors, and individual factors at the age of 52 years. Methods We followed a randomly selected cohort of 429 adolescents that was recruited in 1974 (baseline), when they were 16 years old. The participants completed physical fitness tests, questions about sociodemographic and lifestyle factors at 16, 34, and 52 years of age, and questions about work-related factors and pain in the follow-ups. Logistic regression analyses were used to examine the associations between UBP and the other variables. Results Univariate logistic regression analyses showed that high body mass index and the work-related factors, low control, and low social support at the age of 34 years were related to UBP at the age of 52 years. For social support, there was an interaction between men and women where the relationship between low social support and the experience of pain was more evident for women. Among women, body mass index and social support remained significantly related in the multivariate analyses. For men, social support remained significantly related. Cross-sectional relationships at the age of 52 differed from the longitudinal in the sense that measures of joint flexibility and work posture were also significantly associated with UBP. Conclusion The fact that the cross-sectional differed from the longitudinal relationships strengthens the importance of performing longitudinal studies when studying factors that might influence the initiation of pain. UBP preventative measures might need to include both lifestyle (such as dietary habits and physical activity to ensure that the individuals are not becoming overweight) and work-related factors such as social support.

    Studies using burst comparison procedures to examine age-related changes in intensity discrimination have reported that the ability to discriminate differences in intensity does not reach maturity until late childhood. In the present study, developmental changes in intensity discrimination were examined in 1- to 3-year-old children, using an increment detection paradigm. Children and adults detected increments in a continuous standard presented at three levels ranging from 35 to 55 dB SPL. Adults were also tested at lower levels of the standard in order to permit age comparisons at equivalent sensation levels. Standard stimuli were two-octave bands of noise centered at either 400 or 4000 Hz, and increments were 200 msec in duration. Discrimination performance improved significantly with both age and level of the standard. For all age groups, performance was significantly better for high- than for low-frequency stimuli, but frequency-dependent differences in increment thresholds did not vary reliably with age. Age differences were largest at low levels of the standard. At the highest level (approximately 30 dB nHL), children's difference limens for both low- and high-frequency noise bands were adultlike by 3 years of age. These results suggest that the developmental time course of increment detection is more rapid than that previously reported in burst comparison studies.

    Pregnancy and childbirth among females aged <20 years have been the subject of long-standing concern among the public, the public health community, and policy makers. Teenagers who give birth are much more likely than older women to deliver a low birthweight or preterm infant, and their babies are at higher risk for dying in infancy. The annual public costs associated with births among teenage girls are an estimated $10.9 billion. According to the 2006-2010 National Survey of Family Growth (NSFG), an estimated 77% of births to teenagers aged 15-19 years were unintended.

    In this 8-year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty-four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept-slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high-high (with a large initial vocabulary size and a fast growth rate), low-high (with a small initial vocabulary size and a fast growth rate) and low-low (with a small initial vocabulary size and a slow growth rate) groups. Low-high and low-low groups were distinguishable mostly through phonological skills, morphological skills and other reading-related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language-related and reading-related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.

  12. Diabetes death rates among youths aged ≤ 19 years--United States, 1968-2009.

    2012-11-01

    Although diabetes mellitus most often is diagnosed in adulthood, it remains one of the most common serious chronic diseases of childhood. Youths with diabetes are at risk for diabetes-related mortality because of acute complications that can result from the condition, including diabetic ketoacidosis and hypoglycemia. In the United States in 2010, an estimated 215,000 persons aged ≤ 19 years had diagnosed diabetes. Medical care for diabetes has improved considerably in recent decades, leading to improved survival rates. However, recent trends in diabetes death rates among youths aged <10 years and 10-19 years in the United States have not been reported. To assess these trends, CDC analyzed data from the National Vital Statistics System for deaths in the United States with diabetes listed as the underlying cause during 1968-2009. This report highlights the results of that analysis, which found that diabetes-related mortality decreased 61%, from an annual rate of 2.69 per million for the period 1968-1969 to a rate of 1.05 per million in 2008-2009. The percentage decrease was greater among youths aged <10 years (78%) than among youths aged 10-19 years (52%). These findings demonstrate improvements in diabetes mortality among youths but also indicate a need for continued improvement in diabetes diagnosis and care. PMID:23114253

    Cycloplegic refraction of 1-year-old children is technically possible and is acceptable to mothers as a method for screening children for visual defects. The range of refractions found in a sample of 186 1-year-old children is reported. Prediction of which children are significantly at risk for squint and/or amblyopia is possible on the basis of refractions at age 1 year according to the criteria selected for an 'abnormal' refraction. Bilateral hypermetropia and/or astigmatism or anisometropia at age 1 year was significantly (P less than 1 in 10 000) associated with a child eventually being found to have squint or amblyopia. Both the age of screening and criteria of abnormality will probably need modification. +2.50 or more D hypermetropia in any one meridian of either eye at age 1 year was even more significantly (P = 0.000 000 05%) associated with squint and/or amblyopia. The possibility that meridional hypermetropia could be the basic defect in squint and amblyopia is discussed. PMID:435441

    In children, craniofacial changes due to facial growth complicate facial approximations and require specific knowledge of soft tissue thicknesses (STT). The lack of South African juvenile STT standards of particular age groups, sex and ancestry is problematic. According to forensic artists in the South African Police Service the use of African-American values to reconstruct faces of Black South African children yields poor results. In order to perform a facial approximation that presents a true reflection of the child in question, information regarding differences in facial soft tissue at different ages, sexes and ancestry groups is needed. The aims of this study were to provide data on STT of South African Black and Coloured children and to assess differences in STT with respect to age, sex and ancestry. STT was measured using cephalograms of South African children (n=388), aged 6-13 years. After digitizing the images, STT measurements were taken at ten mid-facial landmarks from each image using the iTEM measuring program. STT comparisons between groups per age, sex and ancestry were statistically analyzed. The results showed that STT differences at lower face landmarks are more pronounced in age groups per ancestry as opposed to differences per age and sex. Generally, an increase in STT was seen between 6-10 year old groups and 11-13 year old groups, regardless of ancestry and sex, at the midphiltrum, labiale inferius, pogonion, and beneath chin landmarks. This research created a reference dataset for STT of South African children of Black and Coloured ancestry per age and sex that will be useful for facial reconstruction/approximation of juvenile remains.

    We investigated changes in the prevalence of myopia and mean changes in refractive errors in Japanese students from 3 to 17 years old from 1984 to 1996. Mass ophthalmologic surveys were performed annually during the course of the study. The age-specific frequency distribution of refractive errors remained similar for 6-year-old students (defined in this study as students in the first grade of primary school) during the 13-year period, but the distribution became gradually skewed toward myopia for 12-year-old students (defined in this study as students in the first grade of junior high school). Comparisons between 1984 and 1996 examinations showed a considerable increase in the incidence of myopia among those 7 years of age or older, and changes in mean refractive errors also demonstrated a greater shift toward myopia, especially in students older than 10 years, for whom the changes were statistically significant. In this 13-year period, the prevalence of myopia increased from 49.3% to 65.6% in 17-year-old students. In addition to the annual mass ophthalmologic examinations, we also performed a longitudinal 6-year study of 346 students who entered junior high school in 1989, 1990, or 1991. Among these students, the prevalence of myopia increased from 43.5% at 12 years of age to 66.0% at 17 years of age. These 346 students were divided into the following eight groups according to their refractive error (spherical power [D]) at 12 years of age: +1 D, 0 D, -1 D, -2 D, -3 D, -4 D, -5 D, and -6 D. Mean progressions of myopia in these students were as follows: for the +1 D group, -0.14 D/year; for the 0 D group, -0.25 D/year; for the -1 D group, -0.37 D/year; for the -2 D group, -0.40 D/year; for the -3 D group, -0.29 D/year; for the -4 D group, -0.25 D/year; for the -5 D group, -0.14 D/year; and for the -6 D group, -0.22 D/year.

    In brief: Cross-sectional studies of physical performance generally show a linear decline in maximum aerobic power (V O2 max) with increasing age (about 1% to 2% per year). In the study described in this article, 15 men were serially followed for 20 years. They performed exercises consisting of walking, running, swimming, and cycling for an average of 3.6 days per week and requiring an energy expenditure of 2,104 kcal per week. Over the 20 years, directly measured V O2 max declined 12% (from 44.4 to 38.9 ml· kg(-1)· min(-1), or 0.27 ml· kg(-1)· min(-1) per year). Essentially no differences were seen in resting heart rate or arterial blood pressure. The authors conclude that physical training forestalls the decline in V O2 max until at least age 65.

    Within-city variation in air pollution has been associated with childhood asthma development, but findings have been inconsistent. We examined whether perinatal air pollution exposure affected asthma onset during "pre-school and "school age" periods in a population-based birth cohort.65,254 children born between 1999 and 2002 in the greater Vancouver metropolitan region were followed until age 10 years using linked administrative health databases. Asthma cases were sex- and age-matched to five randomly chosen controls. Associations between exposure to air pollutants estimated with different methods (interpolation (inverse-distance weighted (IDW)), land use regression, proximity) and incident asthma during the pre-school (0-5 years) and school age (6-10 years) periods were estimated with conditional logistic regression.6948 and 1711 cases were identified during the pre-school and school age periods, respectively. Following adjustment for birthweight, gestational period, household income, parity, breastfeeding at discharge, maternal age and education, asthma risk during the pre-school years was increased by traffic pollution (adjusted odds ratio using IDW method per interquartile increase (95% CI): nitric oxide 1.06 (1.01-1.11), nitrogen dioxide 1.09 (1.04-1.13) and carbon monoxide 1.05 (1.01-1.1)). Enhanced impacts were observed amongst low-term-birthweight cases. Associations were independent of surrounding residential greenness.Within-city air pollution variation was associated with new asthma onset during the pre-school years.

    Objective Our aim was to determine the effects of fetal exposure to propoxur and pyrethroids, on child neurodevelopment at 2 years of age. Patients and Methods Mothers were prospectively recruited during mid-pregnancy in Bulacan, Philippines where multiple pesticides including propoxur, cyfluthrin, chlorpyrifos, cypermethrin, pretilachlor, bioallethrin, malathion, diazinon and transfluthrin are used. To detect prenatal exposure to these pesticides, maternal hair and blood, infant’s hair, cord blood, and meconium were analyzed for the pesticides by gas chromatography/mass spectrometry. Infants were examined at 2 years of age with 95.1% follow up rate and their neurodevelopment outcome was assessed by the Griffiths Mental Developmental Scale (N=754). Results Meconium analysis was the most sensitive method to detect fetal exposure to pesticides and exposure was highest for propoxur (21.3%) and the grouped pyrethroids (2.5% - bioallethrin, transfluthrin, cyfluthrin and cypermethrin). Path analysis modeling was performed to determine the effects of fetal exposure to propoxur and pyrethroids on the child’s neurodevelopment at 24 months of age while controlling for confounders. Only singletons and those with complete data for the path analysis were included (N=696). Using a path analysis model, there was a significant negative (β= −0.14, p<0.001) relationship between prenatal pesticide exposure to propoxur and motor development at 2 years of age after controlling for confounders, e.g., infant gender, socioeconomic status, maternal intelligence, home stimulation (HOME), postnatal exposure to propoxur and blood lead level at 2 years of age. Conclusion At 2 years of age, prenatal exposure to propoxur was associated with poorer motor development in children. PMID:22155319

    Hypertension is a well-known health problem all over the world. Many studies have assessed its prevalence and associated risk factors, but all were cross-sectional and did not evaluate the trend of hypertension through all three different temporal dimensions including age, period, and cohort. So, we aimed to assess the 20-year dynamics of hypertension via the age-period-cohort model. Data from 74,155 subjects aged 25-60 years gathered through five national health surveys (1990-91, 1999, 2003, 2007, and 2011) were used in this study. The age-period-cohort effect on hypertension was analyzed using the intrinsic estimator model. The prevalence of hypertension increased with age for both genders except for males in 2003 and 2011 periods with drops of 3.5% for ages 55-60 and 8.1% for ages 50-60, respectively. As for the period effect, the prevalence of hypertension was almost constant in all age groups for both genders from 1990-1999. The cohort-based prevalence of hypertension showed a declining trend in all cohorts for females except for 2011 in birth cohort of 1950-1955 which remains stationary. The trend of prevalence for males also follows a decreasing trend except for periods of 2003, 2007, and 2011; birth cohorts of 1945-1949, 1975-1980, and 1950-1960 increase by 3.5%, 1.9%, and 8.1%, respectively. The age effect on the prevalence of hypertension showed an almost monotonic increasing trend. The period effect increased the total prevalence of hypertension from 1992 to 1997. The cohort effect also showed a monotonic decrease in hypertension prevalence except for a few discrepancies. PMID:26481410

  20. Use of cessation methods among smokers aged 16-24 years--United States, 2003.

    2006-12-22

    Smoking cessation among adolescent smokers is relatively rare, with approximately 15.6% of smokers aged 12-19 years quitting smoking in a 4-year period (approximately 4% per year). Rates for failed quitting attempts among younger smokers are higher than those for adults (43%), with approximately 58% of high-school smokers having tried to quit at least once for 1 day or longer in the preceding year. To track the history of quitting behavior among smokers aged 16-24 years, Roswell Park Cancer Institute (Buffalo, New York) initiated the 2-year longitudinal National Youth Smoking Cessation Survey (NYSCS) in 2003. This report summarizes key findings from the survey regarding lifetime use of smoking-cessation methods. The findings indicated that smokers aged 16-24 years who had tried to quit were more likely to use unassisted quitting methods than assisted quitting methods; none of the unassisted methods are recommended by the Public Health Service (PHS) clinical guidelines for treatment of tobacco use and dependence, whereas most of the assisted methods are recommended for adults and have been determined to be effective. Many youths aged 16-24 years are trying to quit smoking but often underestimate the rapid progression to tobacco dependence; therefore, PHS clinical practice guidelines for treating tobacco use and dependence recommend that certain clinical interventions proven to be effective among adults be used in youth-based approaches to cessation. In addition, other components of comprehensive tobacco-control programs also increase smoking cessation and should be implemented at CDC-recommended levels to lower tobacco use among youths and adults.

    Background We combined hospital-based surveillance and health utilization survey data to estimate the incidence of respiratory viral infections associated hospitalization among children aged < 5 years in Bangladesh. Methods Surveillance physicians collected respiratory specimens from children aged <5 years hospitalized with respiratory illness and residing in the primary hospital catchment areas. We tested respiratory specimens for respiratory syncytial virus, parainfluenza viruses, human metapneumovirus, influenza, adenovirus and rhinoviruses using rRT-PCR. During 2013, we conducted a health utilization survey in the primary catchment areas of the hospitals to determine the proportion of all hospitalizations for respiratory illness among children aged <5 years at the surveillance hospitals during the preceding 12 months. We estimated the respiratory virus-specific incidence of hospitalization by dividing the estimated number of hospitalized children with a laboratory confirmed infection with a respiratory virus by the population aged <5 years of the catchment areas and adjusted for the proportion of children who were hospitalized at the surveillance hospitals. Results We estimated that the annual incidence per 1000 children (95% CI) of all cause associated respiratory hospitalization was 11.5 (10–12). The incidences per 1000 children (95% CI) per year for respiratory syncytial virus, parainfluenza, adenovirus, human metapneumovirus and influenza infections were 3(2–3), 0.5(0.4–0.8), 0.4 (0.3–0.6), 0.4 (0.3–0.6), and 0.4 (0.3–0.6) respectively. The incidences per 1000 children (95%CI) of rhinovirus-associated infections among hospitalized children were 5 (3–7), 2 (1–3), 1 (0.6–2), and 3 (2–4) in 2010, 2011, 2012 and 2013, respectively. Conclusion Our data suggest that respiratory viruses are associated with a substantial burden of hospitalization in children aged <5 years in Bangladesh. PMID:26840782

    Systematic data regarding early neurodevelopmental functioning in Smith-Magenis syndrome are limited. Eleven children with Smith-Magenis syndrome less than 3 years of age (mean, 19 months; range, 5-34 months) received prospective multidisciplinary assessments using standardized measures. The total sample scored in the moderately to severely delayed range in cognitive functioning, expressive language, and motor skills and exhibited generalized hypotonia, oral-motor abnormalities, and middle ear dysfunction. Socialization skills were average, and significantly higher than daily living, communication, and motor abilities, which were below average. Mean behavior ratings were in the nonautistic range. According to exploratory analyses, the toddler subgroup scored significantly lower than the infant subgroup in cognition, expressive language, and adaptive behavior, suggesting that the toddlers were more delayed than the infants relative to their respective peers. Infants aged approximately 1 year or younger exhibited cognitive, language, and motor skills that ranged from average to delayed, but with age-appropriate social skills and minimal maladaptive behaviors. At ages 2 to 3 years, the toddlers consistently exhibited cognitive, expressive language, adaptive behavior, and motor delays and mildly to moderately autistic behaviors. Combining age groups in studies may mask developmental and behavioral differences. Increased knowledge of these early neurodevelopmental characteristics should facilitate diagnosis and appropriate intervention.

    Estimation of aggregate exposure and risk requires detailed information regarding dermal contact and mouthing activity. We analyzed micro-level activity time series (MLATS) of children aged 7-12 years to quantify these contact behaviors and evaluate differences by age and gender. In all, 18 children, aged 7-12 years, were videotaped while playing outdoors. Video footage was transcribed via Virtual Timing Device (VTD) software. We calculated the hand and mouth contact frequency, hourly duration and median duration of contact with 16 object categories. Median mouthing frequencies were 12.6 events/h and 2.6 events/h for hands and non-dietary objects, respectively. Median hourly mouthing duration was 0.4 min/h and 0.1 min/h with hands and objects. Median mouthing contact duration was 1 s and 1.5 s with hands and objects, respectively. The median object contact frequency for both the hands combined was 537.3 events/h with an hourly contact duration of 81.8 min/h and a median contact duration of 3 s. There were no significant differences in the mouthing activity between genders or age groups. Female children had longer and more frequent hand contacts with several surface types. Age was negatively correlated with hand contacts of floor and wood surfaces. Contact frequencies in this study are higher than current regulatory recommendations for this age group. PMID:21989500

    The objective of the study was to investigate bone mineral density and bone turnover among female students aged 16-24 years in relation to lifestyle factors, such as dietary habits and physical activity, as well as physiological factors, such as age, body weight, and menstrual pattern. Female college and university students (n = 218) were given a validated questionnaire with 34 questions concerning diet, recreational physical activity, alcohol, smoking, menstrual pattern, weight gain and loss. Bone mineral density (BMD) measurements were performed using a heel bone scanner (DEXA). Deoxypyridinoline (DPD) levels were measured in urine samples. The data were analyzed by linear regression and multiple regression analysis. The mean BMD was 0.568 g/cm2. Multiple regression showed that hormonal age was a better predictor of high BMD and low bone mineral turnover than chronological age. The best model predicting high BMD was composed of physical activity, regular menstruation, hormonal age and body weight. Smoking, alcohol consumption and current calcium intake did not contribute to the model. A negative association between BMD and DPD was found, indicating an enhanced bone remodeling. A correlation was found between DPD and hormonal age, chronological age, sugar intake and time with irregular menses. In multiple regression analysis, hormonal age, high sugar intake and weight loss were the factors best predicting DPD. BMD was positively influenced by a healthy lifestyle, including a physically active life and healthy dietary habits without dieting. Our study shows that hormonal age is a stronger BMD predictor than chronological age. Menstrual disturbances might be an indication of a risk for low BMD and might therefore be a reason for measuring BMD among young females.

    This article presents estimates of personal health care spending by age and gender in selected years during the period 2002-10 and an analysis of the variation in spending among children, working-age adults, and the elderly. Our research found that in this period, aggregate spending on children's health care increased at the slowest rate. However, per capita spending for children grew more rapidly than that for working-age adults and the elderly. Per capita spending for the elderly remained about five times higher than spending for children. Overall, females spent more per capita than males, but the gap had decreased by 2010. The implementation of Medicare Part D, the effects of the recent recession, and the aging of the baby boomers affected the spending trends and distributions during the period of this study.

    AIMS—To examine the relation between birth weight and cognitive function at age 11 years, and to examine whether this relation is independent of social class.
METHODS—Retrospective cohort study based on birth records from 1921 and cognitive function measured while at school at age 11 in 1932.Subjects were 985 live singletons born in the Edinburgh Royal Maternity and Simpson Memorial Hospital in 1921. Moray House Test scores from the Scottish Mental Survey 1932 were traced on 449of these children.
RESULTS—Mean score on Moray House Test increased from 30.6 at a birth weight of <2500 g to 44.7 at 4001-4500 g, after correcting for gestational age, maternal age, parity, social class, and legitimacy of birth. Multiple regression showed that 15.6% of the variance in Moray House Test score is contributed by a combination of social class (6.6%), birth weight (3.8%), child's exact age (2.4%), maternal parity (2.0%), and illegitimacy (1.5%). Structural equation modelling confirmed the independent contribution from each of these variables in predicting cognitive ability. A model in which birth weight acted as a mediator of social class had poor fit statistics.
CONCLUSION—In this 1921 birth cohort, social class and birth weight have independent effects on cognitive function at age 11. Future research will relate these childhood data to health and cognition in old age.

    Based on a new model of productivity in age diverse tams, findings from a six-year research program are reported in which data from more than 745 natural teams with 8,848 employees in three different fields (car production, administrative work, financial services) were collected. Moreover, central assumptions of this model were tested with a representative survey of the German workforce (N = 2,000). Results support both significant advantages and disadvantages for age-mixed teams. Based on the findings, the following preconditions for the effectiveness of age diverse teams are identified: high task complexity, low salience and high appreciation of age diversity, a positive team climate, low age-discrimination, ergonomic design of work places, and the use of age differentiated leadership. Based on these insights, we developed a new training for supervisors, which addresses the aforementioned aspects and seeks to improve team performance and health of team members. It was found that the training reduces age stereotypes, team conflicts and enhances innovation. Thus, we can conclude that effective interventions for a successful integration of elderly employees in work groups are available and that combinations of measures that address ergonomic design issues, team composition and leadership are to be strongly recommended for practice.

    A normal coronary angiogram (CA) has been reported to confer a good prognosis. However, how this applies to patients aged ≥65 years is not well known. From 1986 to 1996, 11,625 patients aged ≥65 underwent coronary angiography. We identified 271 patients with either normal (NORM, n = 160) CA or <30% diameter stenosis disease (NEAR-NORM, n = 111). Using the Myocardial Infarction Data Acquisition System, we examined the probability of survival and the risk of developing an ischemic event or undergoing a revascularization procedure during an average of 15.1 ± 6.2 years (range 0.5 to 25.8 years). Matched actuarial subjects were used to compare survival to the general population. The incidence of an ischemic event was low (2.0 events per 100 persons/year for the NORM and 2.8 patients per 100 persons/year for the NEAR-NORM group, p = NS). Rates of revascularization were higher in the NEAR-NORM group compared to the NORM group (1 per 100 persons/year vs 0.5 per 100 persons/year, p = 0.04). During the 25.8-year follow-up, there were 77 deaths (48.4%) for the NORM and 64 (57.1%) for the NEAR-NORM group (χ2 = 1.7, NS). The NORM group survived 6,789 days, 1,517 more days than the actuarial subjects (95% confidence interval [CI] 1,072 to 1,956; p <0.0001) and the NEAR-NORM group survived 5,922 days, 875 more days (95% CI 368 to 1,376; p <0.005). In conclusion, patients with normal or near-normal CA at age ≥65 years have a low rate of myocardial ischemic events and have significantly longer survival than matched subjects from the general population.

    Study Objectives: To examine associations between specific parasomnias and psychotic experiences in childhood. Design: Birth cohort study. Information on the presence of frequent nightmares in children was obtained prospectively from mothers during multiple assessments conducted when children were aged between 2.5 and 9 y. Children were interviewed at age 12 y about nightmares, night terrors, sleepwalking, and psychotic experiences (delusions, hallucinations, and thought interference) occurring in the previous 6 mo. Setting: Assessments were completed in participants' homes or a University clinic within the UK. Patients or Participants: There were 6,796 children (3,462 girls, 50.9%) who completed the psychotic experiences interview. Measurements and Results: Children who were reported by their mothers as experiencing frequent nightmares between 2.5 and 9 y of age were more likely to report psychotic experiences at age 12 y, regardless of sex, family adversity, emotional or behavioral problems, IQ and potential neurological problems (odds ratio (OR) = 1.16, [95% confidence intervals (CI) = 1.00, 1.35], P = 0.049). Children reporting any of the parasomnias at age 12 y also had higher rates of concurrent psychotic experiences than those without such sleeping problems, when adjusting for all confounders (OR = 3.62 [95% CI = 2.57, 5.11], P < 0.001). Difficulty getting to sleep and night waking were not found to be associated with psychotic experiences at age 12 y when controlling for confounders. Conclusion: Nightmares and night terrors, but not other sleeping problems, in childhood were associated with psychotic experiences at age 12 years. These findings tentatively suggest that arousal and rapid eye movement forms of sleep disorder might be early indicators of susceptibility to psychotic experiences.

    BACKGROUND AND OBJECTIVES: Preterm infants commonly have transient hypothyroxinemia of prematurity after birth, which has been associated with deficits in general intellectual functioning, memory, attention, and academic achievement. However, research has predominantly focused on thyroxine levels in the first 2 weeks of life and outcomes are limited to the preschool period. Our objective was to evaluate the relationships between free thyroxine (fT4) levels over the first 6 weeks after very preterm (VPT) birth with cognitive functioning and brain development at age 7 years. METHODS: A total of 83 infants born VPT (<30 weeks’ gestation) had fT4 concentrations measured postnatally and 2- and 6-week area under the curve (AUC) summary measures were calculated. Follow-up at age 7 years included a neuropsychological assessment and brain MRI. Univariable and multivariable regression modeling was used where AUC for fT4 was the main predictor of neurodevelopmental outcome at age 7 years. RESULTS: Multivariable modeling revealed that higher, not lower, postnatal fT4 levels (2-week AUC) were associated with poorer cognitive performances at age 7 years on tasks of verbal learning (P = .02), verbal memory (P = .03), and simple reaction time (P < .001). A similar pattern of results was found when the 6-week AUC was examined. No significant associations between postnatal fT4 levels and brain volumes at age 7 years were identified. CONCLUSIONS: Results are contradictory to previous observations and suggest that after adjustment for confounders, higher postnatal fT4 levels in VPT infants, rather than lower levels, may be a marker of adverse neuropsychological development in childhood.

    Although atherosclerosis starts in early life, evidence on risk factors and atherosclerosis in individuals aged <45 years is scarce. Therefore, we studied the relationship between risk factors, common carotid intima-media thickness (CIMT), and first-time cardiovascular events in adults aged <45 years. Our study population consisted of 3067 adults aged <45 years free from symptomatic cardiovascular disease at baseline, derived from 6 cohorts that are part of the USE-IMT initiative, an individual participant data meta-analysis of general-population-based cohort studies evaluating CIMT measurements. Information on risk factors, CIMT measurements, and follow-up of the combined end point (first-time myocardial infarction or stroke) was obtained. We assessed the relationship between risk factors and CIMT and the relationship between CIMT and first-time myocardial infarction or stroke using a multivariable linear mixed-effects model and a Cox proportional-hazards model, respectively. During a follow-up of 16.3 years, 55 first-time myocardial infarctions or strokes occurred. Median CIMT was 0.63 mm. Of the risk factors under study, age, sex, diastolic blood pressure, body mass index, total cholesterol, and high-density lipoprotein cholesterol related to CIMT. Furthermore, CIMT related to first-time myocardial infarction or stroke with a hazard ratio of 1.40 per SD increase in CIMT, independent of risk factors (95% confidence interval, 1.11-1.76). CIMT may be a valuable marker for cardiovascular risk in adults aged <45 years who are not yet eligible for standard cardiovascular risk screening. This is especially relevant in those with an increased, unfavorable risk factor burden. PMID:25624341

    Objectives. We investigated 50-year US trends in age at menarche by socioeconomic position (SEP) and race/ethnicity because data are scant and contradictory. Methods. We analyzed data by income and education for US-born non-Hispanic Black and White women aged 25 to 74 years in the National Health Examination Survey (NHES) I (1959–1962), National Health Examination and Nutrition Surveys (NHANES) I–III (1971–1994), and NHANES 1999–2008. Results. In NHES I, average age at menarche among White women in the 20th (lowest) versus 80th (highest) income percentiles was 0.26 years higher (95% confidence interval [CI] = −0.09, 0.61), but by NHANES 2005–2008 it had reversed and was −0.33 years lower (95% CI = −0.54, −0.11); no socioeconomic gradients occurred among Black women. The proportion with onset at younger than 11 years increased only among women with low SEP, among Blacks and Whites (P for trend < .05), and high rates of change occurred solely among Black women (all SEP strata) and low-income White women who underwent menarche before 1960. Conclusions. Trends in US age at menarche vary by SEP and race/ethnicity in ways that pose challenges to several leading clinical, public health, and social explanations for early age at menarche and that underscore why analyses must jointly include data on race/ethnicity and socioeconomic position. Future research is needed to explain these trends. PMID:25033121

    BACKGROUND: The proportion of older patients in the community is rising. The aim of this study was to determine the trend in emergency surgical admissions in patients over 80 years of age in 1997 compared with the previous three decades. PATIENTS AND METHODS: Data were obtained on all patients over 80 years of age admitted as general surgical emergencies in 1997 to the Royal Berkshire and Battle Hospitals, Reading, UK. Reasons for admission, management, mortality and duration of hospital stay were recorded and compared with results from 1966, 1976 and 1989. RESULTS: During 1997, 4807 patients over the age of 80 years were admitted as emergencies to all specialities. Of these, 447 (9.3%) were surgical. This compares with 122 in 1966, 248 in 1976 and 339 in 1989. Emergency surgical workload in patients over 80 years of age had increased from 6.2% in 1966 to 12% in 1997. A random sample of 261 patients was analysed. In-patient mortality was 13.8% in 1997 compared with 21.8% for 1976 and 22.4% for 1989. Median length of stay was 8 days (range, 0-41 days) for 1997 and 1989 compared with 14 days in 1976. Twenty-four patients either needed admission to other specialities or need not have been admitted as emergencies at all and were classified as inappropriate admissions to the general surgical ward. CONCLUSIONS: The trend of increased number of patients over the age of 80 years being admitted as emergencies to general surgery continues through four decades. There has been a decrease in mortality and length of stay since 1966, but no decrease in length of stay in 1997 compared with 1989. Avoiding inappropriate admissions would result in a significant improvement in bed utilisation for elective surgery and help to reduce waiting lists. PMID:11103155

    Enhanced eye-hand coordination (EHC) is associated with greater participation in physical activity. No longitudinal studies have examined the change in throw-catch EHC from childhood to mid-adolescence. We investigated the development of EHC with an object control test from childhood to mid-adolescence in boys and girls. Evaluated at age 8, 10, 12 and 16 years, EHC was measured as the aggregate success rate of a throw and wall-rebound catch test. The test involved 40 attempts of progressive increasing difficulty, as determined by increased distances from a wall and transitions from two-handed to one-handed catches. Outcomes were treated as quasi-binomial and modelled by generalised linear mixed logistic regression analysis. EHC improved with age from childhood to mid-adolescence, although boys were more adept at each age (p<0.001). The patterns of change in EHC with increasing age varied according to the degree of difficulty of the task (p<0.001); throw and two-handed catch proficiency developing earlier than throw and one-handed catch in both sexes. Boys' EHC was better than girls' as early as age 8 years and male proficiency was maintained through to mid-adolescence. The proficiency of throw and two-handed catch rates developed faster than throw and one-handed catch rates for both sexes.

    Transabdominal pelvic ultrasound and/or pelvic Magnetic Resonance Imaging are safe, accurate and non-invasive means of determining the size and configuration of the internal female genitalia. The assessment of uterine size and volume is helpful in the assessment of many conditions including disorders of sex development, precocious or delayed puberty, infertility and menstrual disorders. Using our own data from the assessment of MRI scans in healthy young females and data extracted from four studies that assessed uterine volume using transabdominal ultrasound in healthy females we have derived and validated a normative model of uterine volume from birth to age 40 years. This shows that uterine volume increases across childhood, with a faster increase in adolescence reflecting the influence of puberty, followed by a slow but progressive rise during adult life. The model suggests that around 84% of the variation in uterine volumes in the healthy population up to age 40 is due to age alone. The derivation of a validated normative model for uterine volume from birth to age 40 years has important clinical applications by providing age-related reference values for uterine volume.

    The contribution of genetic factors to blood pressure levels is well established. The contribution of genes to the longitudinal change in blood pressure has been less well studied, because of the lack of longitudinal family data. The present study investigated a possible major-gene effect on the observed increase with age in diastolic blood pressure (DBP) levels. Subjects included 965 unmedicated adults (age {ge}18 years) in 73 pedigrees collected in Utah as part of a longitudinal cardiovascular family study. Segregation analysis of DBP change over 7.2 years of follow-up identified a recessive major-gene effect with a gene frequency of p = .23. There was also a significant age effect on the genotypic means, which decreased expression of the major gene at older ages. For those inferred to have the genotype responsible for large DBP increases, DBP increased 32.3%, compared with a 1.5% increase in the nonsusceptible group (P < .0001). The relative risk of developing hypertension between the susceptible and nonsusceptible groups after 7.2 years was 2.4 (P = .006). Baseline DBP reactivities to mental arithmetic (P < .0001) and isometric hand-grip (P < .0001) stress tests were greatest in those assigned to the susceptible genotype. We conclude that age-related changes in DBP are influenced by a major gene. Characteristics of this major-gene effect for greater age-related blood pressure increases include greater reactivity to mental and physical stressors. The present study thus provides evidence for genetic control of changes in blood pressure, in addition to the previously suggested genetic control of absolute blood pressure level. 28 refs., 6 tabs.

    Polyphenols have been suggested as protective factors for a range of chronic diseases. However, studying the impact of individual polyphenols on health is hindered by the intrinsic inter-correlations among polyphenols. Alternatively, studying foods rich in specific polyphenols fails to grasp the ubiquity of these components. Studying overall dietary patterns would allow for a more comprehensive description of polyphenol intakes in the population. Our objective was to identify clusters of dietary polyphenol intakes in a French middle-aged population (35-64 years old). Participants from the primary prevention trial SUpplementation en VItamines et Minéraux AntioXydants (SU.VI.MAX) study were included in the present cross-sectional study (n 6092; 57·8 % females; mean age 48·7 (sd 6·4) years). The fifty most consumed individual dietary polyphenols were divided into energy-adjusted tertiles and introduced in a multiple correspondence analysis (MCA), leading to comprehensive factors of dietary polyphenol intakes. The identified factors discriminating polyphenol intakes were used in a hierarchical clustering procedure. Four clusters were identified, corresponding broadly to clustered preferences for their respective food sources. Cluster 1 was characterised by high intakes of tea polyphenols. Cluster 2 was characterised by high intakes of wine polyphenols. Cluster 3 was characterised by high intakes of flavanones and flavones, corresponding to high consumption of fruit and vegetables, and more broadly to a healthier diet. Cluster 4 was characterised by high intakes of hydroxycinnamic acids, but was also associated with alcohol consumption and smoking. Profiles of polyphenol intakes allowed for the identification of meaningful combinations of polyphenol intakes in the diet. PMID:27547391

    Numerous studies have identified the effects of prematurity on the neonate's physical health, however few studies have explored the effects of prematurity on both the physical and mental health of the child as they develop. Secondary analysis of data from the Millennium Cohort Study, a longitudinal study of infants (n = 18 818, born 2000-2002 in the United Kingdom) was performed. Effects of gestational age at birth on health outcomes at 5 years were measured using parental rating of their children's general health and severity of behavior problems. The association between parent's general health ratings and behavior problem ratings was low: 86% of those reporting serious behavior problems (5% of the sample, n = 764) rated their child as being in excellent, very good, or good health. Still, a gradient of increasing risk of poorer outcome with decreasing gestational age was observed for a composite health measure (poor/fair health and/or serious behavior problems), suggesting an association with prematurity for this composite assessment of health status. The greatest contribution to the childhood composite health measure at 5 years was for children born at 32-36 weeks gestation: population attributable fractions for having poor outcomes was 3.4% (Bonferroni-adjusted 95% confidence interval 1.1%-6.2%), compared to 1% (0.2-2.3) for birth at less than 32 weeks. Results suggest that preterm children, by school entry, are not only at high risk of physical health problems, but also of behavioral health problems. The recognition of, and response to comprehensive health and well-being outcomes related to prematurity are important in order to correctly plan and deliver adequate paediatric health services and policies.

    Background Animal data show that decreased activity of placental 11-beta-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which potently inactivates glucocorticoids (e.g. cortisol) to inert forms (cortisone), allows increased access of maternal glucocorticoids to the fetus and 'programs' hypertension. Data in humans are limited. We examined in humans the association between venous umbilical cord blood glucocorticoids, a potential marker for placental 11β-HSD2 enzyme activity, and blood pressure at age 3 years. Methods Among 286 newborns in Project Viva, a prospective pre-birth cohort study based in eastern Massachusetts, we measured cortisol (F) and cortisone (E) in venous cord blood and used the ratio of F/E as a marker for placental 11β-HSD2 activity. We measured blood pressure (BP) when the offspring reached age 3 years. Using mixed effects regression models to control for BP measurement conditions, maternal and child characteristics, we examined the association between the F/E ratio and child BP. Results At age 3 years, each unit increase in the F/E ratio was associated with a 1.6 mm Hg increase in systolic BP (95% CI 0.0 to 3.1). The F/E ratio was not associated with diastolic blood pressure or birth weight for gestational age z-score. Conclusion A higher F/E ratio in umbilical venous cord blood, likely reflecting reduced placental 11β-HSD2 activity, was associated with higher systolic blood pressure at age 3 years. Our data suggest that increased fetal exposure to active maternal glucocorticoids may program later systolic blood pressure. PMID:18755017

    Objectives: The aim of this study was to evaluate the proportion of completed treatments and to study the factors affecting the full mouth dental rehabilitation in pediatric patients treated by undergraduate students at the College of Dental Medicine Teaching Clinics, University of Sharjah. Materials and Methods: A retrospective study was conducted on 270 children aged less than 12 years (mean age 7.6, SD 2.04). Comprehensive dental rehabilitation reports of child patients that were completed by final year dental undergraduate students from the year 2009 to 2011 were reviewed. Data on complete history, oral examination, dental charting, and treatment plan were collected from pediatric dentistry case sheet. Dental caries was charted using WHO 1997 criteria. Dental treatment needs and completion of dental care delivered to children involved in this study were assessed using DMFT/deft scores. Results: Percentages of treatment provided included completed restorations (94%) and space management (84%) in primary dentition, whereas 98% of restoration and 94% of required sealants were completed in permanent dentition. The percentage of completed dental treatment including sealant placement was 61%. Age of the child and the number of decayed teeth present before the start of the treatment significantly correlated with the children in the incomplete treatment category (P < 0.05). Conclusions: Therefore, a worthy dental care was provided in a holistic approach to the children attending College of Dental Medicine training clinics. Age of the child and the number of decayed teeth were the factors affecting dental rehabilitation in children aged 3–12 years. PMID:26236683

    Objective To test the hypothesis that asymptomatic Alzheimer disease lesions may appear before 50 years of age. Background Alzheimer disease has an asymptomatic stage during which people are cognitively intact despite having substantial pathologic changes in the brain. While this asymptomatic stage is common in older people, how early in life it may develop has been unknown. Methods We microscopically examined the postmortem brains of 154 people aged 30-39 years (n = 59) and 40-50 years (n = 95) for specific Alzheimer lesions: beta-amyloid plaques, neurofibrillary tangles, and tau-positive neurites. We genotyped DNA samples for the apolipoprotein E gene (APOE). Results We found beta-amyloid lesions in 13 brains, all of them from people aged 40 to 49 with no history of dementia. These plaques were of the diffuse type only and appeared throughout the neocortex. Among these 13 brains, 5 had very subtle tau lesions in the entorhinal cortex and/or hippocampus. All individuals with beta-amyloid deposits carried 1 or 2 APOE4 alleles. Among the individuals aged 40 to 50 with genotype APOE3/4, 10 (36%) had beta-amyloid deposits but 18 (64%) had none. Conclusions Our study demonstrates that beta-amyloid deposits in the cerebral cortex appear as early as 40 years of age in APOE4 carriers, suggesting that these lesions may constitute a very early stage of Alzheimer disease. Future preventive and therapeutic measures for this disease may have to be stratified by risk factors like APOE genotype and target people in their 40s or even earlier. PMID:26413742

    Skin colour variation with increasing age was analysed using a cross-sectional sample of 796 Basque boys aged from 8 to 19 years. Measurements were taken at the upper inner arm and forehead by means of an EEL DS29 Digital Unigalvo reflectance spectrophotometer with a nine-filter head. Ontogenic changes of skin pigmentation were found to be statistically significant. The influence of the month in which measurements were taken on reflectance values has been studied. Comparisons with another similar study (Pembrokeshire, Wales population) were carried out.

  9. Nutrition through the life span. Part 3: adults aged 65 years and over.

    PubMed

    Shepherd, Alison

    The UK has an ageing population, but this is not being matched by a similar increase in healthy life expectancy. The greatest challenge in the 21st century will be to improve the quality of life as ageing occurs. Health is the most important prerequisite for people to enjoy life in their older years (Brundtland, 1988). Diet is one factor that is believed to play a key role in the prevention and treatment of chronic diseases associated with ageing. The third and final part of this series addressing the concept of nutrition through the lifespan seeks to educate health-care professionals as to what constitutes a healthy diet for the elderly population, and gives practical guidance as to how to try and prevent the ever-growing problem of malnutrition within this age group. It is suggested that when the older adult is hospitalized their risk of malnutrition increases. Therefore, some guidance for the use of oral nutritional supplements in this population is given. Good nutrition and physical exercise are essential for healthy ageing from both a physical and psychological perspective (NICE, 2008). Therefore a multidisciplinary life course approach to ageing is vital to minimizing its complications for quality of life and subsequent public health (Denny, 2008).

    Several indicators have been used to analyze scientific journals, with the impact factor and the number of citations in a 2-yr calendar time frame (2-YRC) being the most common factors. However, considering that the Journal of Applied Physiology (JAPPL) appears monthly and that calculations of these indicators are based on citations of papers published in previous years, we hypothesized that articles published at the beginning of the year would be cited more in the 2-YRC compared with those appearing in the last issues of the year, a phenomena known as a relative age effect. Our objective was to confirm the existence of a relative age effect in the 2-YRC for original articles published in JAPPL. From 2005 to 2008, a total of 1,726 original articles were published, according to the Web of Science, and 9,973 citations in 2-YRC, varying from 0 to 45, with a mean of 5.78 for individual papers. Although there were no differences in the number of original articles published in a given month (P = 0.99), the 2-YRC varied considerably throughout the year, being higher for those earlier issues of the year, as shown by the linear regression analysis (r(2) = 0.76; P < 0.001). The 2-YRC began at 6.62 during the first 3 mo of the year, dropping by 10% at each 3-mo period. In summary, the longer an article has been out there, the more citations it collects. The relative age effect is a potential confounding variable for the assessment and interpretation of 2-YRC (using calendar years) from JAPPL original articles.

    In typically developing children, drawing development occurs in stages from uncontrolled strokes to complex drawing. In this study, we examined drawing development in children with neurodevelopmental delay (NDD). In order to do so, we observed the influence of age, intraventricular hemorrhage (IVH) and gender on the development of drawing skills. The sample consisted of 52 children with NDD, aged 2 years and 6 months to 5 years. All children were hospitalized for multidisciplinary team monitoring and developmental support. The evaluation of drawing development was administered by giving each child a blank A4 paper and the instruction to draw anything they wanted. All of the drawings were scored satisfactory or unsatisfactory. Descriptive statistics was employed on all relevant data to show results in frequencies and percentages. In order to determine differences between groups, the χ2-test was administered. The results showed greatest difference in drawing in children aged from 3 years to 3 years and 11 months. Children with lower IVH had better drawing scores than children with higher IVH levels. According to gender dissimilarities, a difference was found showing girls to have better drawing skills than boys. All study results pointed to the importance of early rehabilitation and continuous structured work with children with NDD. PMID:26415307

  12. Tobacco use among students aged 13-15 years--Baghdad, Iraq, 2008.

    In 2008, Iraq's parliament ratified the World Health Organization Framework Convention on Tobacco Control (WHO FCTC), which obligates participants to establish tobacco use monitoring, surveillance, and evaluation systems. Lack of data on adolescent tobacco use in Iraq led the Ministry of Health (MOH) to conduct the Global Youth Tobacco Survey (GYTS) in Baghdad in 2008. GYTS is a school-based survey of students aged 13--15 years that is self-administered in classes in selected schools. As in most Middle East countries, tobacco use in Iraq takes the form of cigarettes and shisha. Based on GYTS results, 7.4% of students aged 13--15 years reported having ever smoked cigarettes, 12.9% had ever smoked shisha, 3.2% currently smoked cigarettes, and 6.3% currently smoked shisha. Among never smokers aged 13--15 years, 13.0% reported they were likely to initiate cigarette smoking in the next year. Future declines in adolescent tobacco use in Iraq (and Baghdad) could be enhanced by expanding existing tobacco control programs to include prevention and cessation of the use of cigarettes and shisha, implementing measures that discourage adolescents who have never smoked from initiating tobacco use, expanding legislation to ban exposure to secondhand smoke in all indoor workplaces, and enacting legislation banning pro-tobacco advertising and sponsorship.

    Children born very preterm are at greater risk of ophthalmic morbidities, including strabismus, than children born at term. We evaluated perinatal factors associated with strabismus at age 2 years in a large population of infants delivered before 28 weeks' gestation. A total of 996 infants in the multicenter ELGAN (Extremely Low Gestational Age Newborn) study who had a retinal exam in infancy and a developmental assessment at 2 years corrected age are included. Their mothers were interviewed about the pregnancy, and both mother and newborn charts were reviewed. Certified examiners administered the Bayley Scales of Infant Development-II and performed an examination of ocular alignment. Time-oriented logistic regression risk models were created to evaluate the associations of characteristics and exposures with the development of strabismus. Overall, 14% (n = 141) of the children had strabismus at 2 years, and 80% of strabismic children had esotropia. Characteristics associated with strabismus were birth before 26 weeks' gestation, severe fetal growth restriction, and maternal history of aspirin ingestion. Associated postnatal factors included a SNAP-II (Score for Neonatal Acute Physiology) illness severity value ≥ 30, brain ventriculomegaly, type I retinopathy of prematurity, and ventilator-dependent severe bronchopulmonary dysplasia. Strabismus in very preterm populations is associated with a number of antenatal and postnatal antecedents as well as clinical and imaging correlates indicative of brain damage in these children. Routine ophthalmologic assessments in the early years can allow appropriate and timely interventions.

    Objective To examine relationships between prenatal perfluoroalkyl substance (PFAS) exposure and adiposity in children born to women who lived downstream from a fluoropolymer manufacturing plant. Methods Data are from a prospective cohort in Cincinnati, OH (HOME Study). We measured perfluorooctanoic (PFOA), perfluorooctane sulfonic (PFOS), perfluorononanoic (PFNA), and perfluorohexane sulfonic (PFHxS) acids in prenatal serum samples. We estimated differences in body mass index z-scores (BMI), waist circumference, and body fat at 8 years of age (n=204) and BMI between 2–8 years of age (n=285) according to PFAS concentrations. Results Children born to women in the top two PFOA terciles had greater adiposity at 8 years than children in the 1st tercile. For example, waist circumference (cm) was higher among children in the 2nd (4.3; 95% CI:1.7, 6.9) and 3rd tercile (2.2; 95% CI:−0.5, 4.9) compared to children in the 1st tercile. Children in the top two PFOA terciles also had greater BMI gains from 2–8 years compared to children in the 1st tercile (p<0.05). PFOS, PFNA and PFHxS were not associated with adiposity. Conclusions In this cohort, higher prenatal serum PFOA concentrations were associated with greater adiposity at 8 years and a more rapid increase in BMI between 2–8 years. PMID:26554535

    In 2014, an estimated 2.8 million persons aged ≥65 years in the United States reported severe vision impairment* defined as being blind or having severe difficulty seeing, even with eyeglasses. Good vision is important for maintaining balance as well as for identifying low-contrast hazards, estimating distances, and discerning spatial relationships. Conversely, having poor vision increases the risk for falls (1,2). Falls among older adults are common and can cause serious injuries, disabilities, and premature death (1,3). To date, no state-level investigations have examined the annual prevalence of falls among persons with and without severe vision impairment. CDC analyzed data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) to estimate the state-specific annual prevalence of falls among persons aged ≥65 years with and without self-reported severe vision impairment. Overall, 46.7% of persons with, and 27.7% of older adults without, self-reported severe vision impairment reported having fallen during the previous year. The state-specific annual prevalence of falls among persons aged ≥65 years with severe vision impairment ranged from 30.8% (Hawaii) to 59.1% (California). In contrast, the prevalence of falls among persons aged ≥65 years without severe vision impairment ranged from 20.4% (Hawaii) to 32.4% (Alaska). Developing fall-prevention interventions intended for persons with severe vision impairment will help states manage the impact of vision impairment and falls on health care resources, and can inform state-specific fall prevention initiatives.

    The aim of the study was to determine arterial blood pressure response to exercise in young athletes. The study group comprised 711 young athletes (457 boys, 254 girls) aged 10 to 18 years (mean 13.41 ± 3.12 years) who had been training for an average of 7.62 ± 4.2 h per week for an average of 4.01 ± 2.5 years. Participants with elevated arterial blood pressure above the 90th percentile at rest were excluded from investigation. A symptom-limited, multistage exercise test to exhaustion was performed using a Monark cycle ergometer. Arterial blood pressure was measured with an aneroid manometer in the third minute of each stage of the test. Mean systolic arterial blood pressure during peak exercise was significantly higher in boys than in girls: 183.21 ± 27.97 mm Hg and 170.97 ± 21.4 mm Hg, respectively (p = 0.03). Multivariate linear regression analysis showed that age and workload had significant effects on arterial blood pressure during the test. Systolic arterial blood pressure during the exercise can be described with the following equations: boys, SBPex (mm Hg) = -1.92 × age (years) + 0.55 × workload (W) + 120.84; girls, SBPex (mm Hg) = -0.88 × age (years) + 0.48 × workload (W) + 111.22. The study results describe reference values of arterial blood pressure during the exercise test. The presented equations and figures can help to assess whether the arterial blood pressure at each stage of the exercise test exceeds the normal range or not.

    The study presents neuropsychiatric profiles of children aged 11 with autism spectrum disorder, assessed before 4.5 years, and after interventions. The original group comprised a community sample of 208 children with ASD. Parents of 128 participated-34 with average intellectual function, 36 with borderline intellectual function and 58 with intellectual disability. They were interviewed using the Autism-Tics, AD/HD and other Comorbidities interview. Criteria for a clinical/subclinical proxy of ASD were met by 71, 89 and 95 %, respectively. Criteria for at least one of ASD, AD/HD, Learning disorder or Developmental Coordination Disorder were met by 82, 94 and 97 %. More than 90 % of children with a preschool diagnosis of ASD have remaining neuropsychiatric problems at 11, despite early intervention. PMID:27230761

    Habitual consumption of dairy products has been shown to play an important role in the prevention of several chronic diseases. We aimed to prospectively assess the relationship between the change in dairy product consumption (both regular fat and low/reduced fat) and the 15-year incidence of age-related macular degeneration (AMD). In the Blue Mountains Eye Study, 2037 participants aged 49 years or above at baseline were re-examined at follow-up in 1997-9, 2002-4 and/or 2007-9. AMD was assessed from retinal photographs. Dietary data were collected using a semi-quantitative FFQ, and servings of dairy product consumption calculated. Over the 15-year follow-up, there were 352, 268 and eighty-four incident cases of any, early and late AMD, respectively. After adjusting for age, sex, current smoking, white cell count and fish consumption, a significant linear trend (P for trend = 0·003) was observed with decreasing consumption of total dairy foods and the 15-year incidence of late AMD, comparing the lowest v. highest quintile of intake (OR 2·80, 95 % CI 1·21, 3·04). Over the 15 years, decreased consumption of reduced-fat dairy foods was associated with an increased risk of incident late AMD, comparing the lowest to highest quintile of intake (OR 3·10, 95 % CI 1·18, 8·14, P for trend = 0·04). Decreasing total dietary Ca intake over the 15 years was also associated with an increased risk of developing incident late AMD (multivariable-adjusted P for trend = 0·03). A lower consumption of dairy products (regular and low fat) and Ca was independently associated with a higher risk of developing incident late AMD in the long term. Additional cohort studies are needed to confirm these findings.

    The objectives of this study were to determine prognostic predictors for ambulation among Thai children with cerebral palsy and identify their ambulatory status. A retrospective cohort study was performed at 6 special schools or hospitals for children with physical disabilities. The prognostic predictors for ambulation were analyzed by multivariable ordinal continuation ratio logistic regression. The 533 participants aged 2 to 18 years were divided into 3 groups: 186 with independent ambulation (Gross Motor Function Classification System [GMFCS I-II]), 71 with assisted ambulation (Gross Motor Function Classification System III), and 276 with nonambulation (Gross Motor Function Classification System IV-V). The significant positive predictors for ambulation were type of cerebral palsy (spastic diplegia, spastic hemiplegia, dyskinesia, ataxia, hypotonia, and mixed type), sitting independently at age 2 years, and eating independently. These predictors were used to develop clinical scoring for predicting the future ability to walk among Thai children with cerebral palsy.

    The infection rate and relationship of enterobiasis with socio-economic status were determined in children aged 1-8 years, living in a rural area in Malaysia. Of the 178 subjects 40.4% were infected with Enterobius vermicularis. The distribution of enterobiasis among these children were analyzed in relation to age groups and sex. The rate of infection was significantly higher in older children (5-7 years). The association of enterobiasis with other factors studied such as number of persons per house, household income per months and mother's employment status were not significant. The sensitivity of three successive days anal swabs compared to a single swab was found to be statistically significant.

    Fertility decreases with advancing age. This study retrospectively reviewed the results of ovarian stimulation and intrauterine insemination (IUI) in women 40 years old with diminished ovarian reserve or unexplained infertility who underwent treatment with ovarian stimulation/IUI with clomiphene citrate or gonadotrophin and compared them with the results of IVF and in-vitro maturation (IVM) treatments. The main outcome measures were pregnancy and live-birth rates. The profiles of the patients in ovarian stimulation, IVM and IVF groups were comparable. There were no clinical pregnancies in the clomiphene citrate and IVM groups. The clinical-pregnancy rates in the gonadotrophin and IVF groups were 2.6% and 16.9% and the live-birth rates were 2.6% and 13.7%, respectively. Compared with ovarian stimulation, IVF is most effective for women aged 40 years or more. Attempting success with ovarian stimulation or IVM will delay conception unnecessarily. PMID:22197126

    Very few exposure data are available for children in Europe and worldwide. The aim of this study was to assess the exposure to cosmetic products used on children aged 0-3 years using recent consumption data generated for the French population. Exposure was assessed using a probabilistic method for 24 products including cleanser, skin care, fragrance, solar and bottom products. The exposure data obtained in this study for children aged 0-3 years were higher than the values fixed by the SCCS for all common products: liquid shampoo, face moisturizer cream, toothpaste, shower gel and body moisturizer cream. Exposure was assessed for the first time for many products such as sunscreens, Eau de toilette and massage products. These new French exposure values will be useful for safety assessors and for safety agencies. PMID:27255804

    The aim of this study was to determine the reliability of the squat jump test (SJ) and countermovement jump test (CMJ), in fifty-six children (30 girls and 26 boys) with ages ranging from 6 to 8 years. Each subject performed two evaluation sessions (T1, T2) with seven days between tests. The results show that the CMJ test has a high intratrial reproducibility in T1 and T2 measured through intraclass correlation coefficient (ICC ≥ 0.95). The ICC for the SJ test had a high value (0.99) only in T1. The variability for both tests among children under 9 years of age is higher than those reported for adult subjects in other studies. The intersession reliability was questionable with a high methodical error (ME= 9.86-15.1%, for the SJ and CMJ, respectively) and a significant worsening of the results of CMJ in T2 (p < .05).

    The study reported here examined the developmental antecedents of conservative versus liberal ideologies using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development and a follow-up study conducted when the sample was 18 years old. Specifically, we examined variation in conservative versus liberal ideologies at age 18 years as a function of parenting attitudes and child temperament during the first 5 years of life. Consistent with long-standing theories on the development of political attitudes, our results showed that parents' authoritarian attitudes assessed when children were 1 month old predicted conservative attitudes in those children more than 17 years later. Consistent with the findings of Block and Block (2006), our results also showed that early childhood temperament predicted variation in conservative versus liberal ideologies.

    Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N = 119) and rural (N = 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender. PMID:22774425

    The increase in life expectancy worldwide has resulted in a greater prevalence of chronic non-communicable diseases. This study aims to evaluate the prevalence and factors associated with the occurrence of cancer among Brazilian women over the age of 50. A cross-sectional study with 622 women over the age of 50 was performed using a population survey. The outcome variable was the occurrence of a malignant tumor in any location. The independent variables were sociodemographic characteristics, self-perception of health, health-related habits and morbidities. Statistical analysis was carried out using the chi-square test and Poisson regression. The mean age of the women was 64.1 years. The prevalence of cancer was 6.8%. The main sites of occurrence of malignant tumors were the breast (31.9%), colorectal (12.7%) and skin (12.7%). In the final statistical model, the only factor associated with cancer was smoking > 15 cigarettes/day either currently or in the past: PR 2.03 (95% CI 1.06-3.89). The results have improved understanding of the prevalence and factors associated with cancer in Brazilian women aged 50 years or more. They should be encouraged to maintain a healthy lifestyle and pay particular attention to modifiable risk factors such as smoking.

    As part of the Light Water Reactor Sustainability Program, science - based engineering approaches were employed to address cable degradation behavior under a range of exposure environments. Experiments were conducted with the goal to provide best guidance for aged material states, remaining life and expected performance under specific conditions for a range of cable materials. Generic engineering tests , which focus on rapid accelerated aging and tensile elongation , were combined with complementar y methods from polymer degradation science. Sandia's approach, building on previous years' efforts, enabled the generation of some of the necessary data supporting the development of improved lifetime predictions models, which incorporate known material b ehaviors and feedback from field - returned 'aged' cable materials. Oxidation rate measurements have provided access to material behavior under low dose rate thermal conditions, where slow degradation is not apparent in mechanical property changes. Such da ta have shown aging kinetics consistent with established radiati on - thermal degradation models.

    The aim of this study was to assess the immunoexpression of human papillomavirus genotypes 16 and 18 (E6 and E7) oncoproteins in cervical high-grade squamous intraepithelial lesions (HSIL) of human immunodeficiency virus (HIV)-positive women. These results were also compared to the persistence and/or recurrence of lesions after loop electrosurgical excision procedure. Cervical samples from 158 patients were divided into three groups according to the presence or absence of HSIL in women who were or were not HIV-positive. By using the tissue microarray technique, immunohistochemistry was performed to analyze the expression of HPV 16/18 E6 and E7 oncoproteins. Cervical samples from 95 HIV-positive women and 63 HIV-negative women were studied. A statistically significant difference was found in the immunoexpression of E6 and E7 oncoproteins in samples from HIV-positive women with HSIL and that of women with non-neoplastic tissue (P < 0.001). There was also a statistically significant correlation between the immunoexpression of E6 (P = 0.012) and E7 (P < 0.001) oncoproteins in lesion persistence among HIV-positive women. Within the limitations of this study, the immunoexpression of HPV 16/18 E6 and E7 oncoproteins may have prognostic value regarding lesion persistence in HIV-positive women. PMID:26909984

    The feasibility of pancreaticoduodenectomy (PD) for elderly patients is controversial. Of 51 patients with pancreatic or bile duct tumor who underwent PD (except portal vein resection), the surgical results of 27 elderly patients aged 75 years or older (elderly group) we retrospectively evaluated and compared with those of 24 patients younger than 75 years (younger group). Although ASA-PS was significantly higher in the elderly group, we did not observe any significant difference in other background characteristics, complications, or length of hospital stay between the two groups. This study suggests that PD is probably safe and feasible with the appropriate surgical indication for elderly patients.

    To know the clinical characteristics of pituitary adenomas in the elderly patients aged 80 years or older who were surgically treated. From 1995 through 2012, 907 patients underwent surgery for the pituitary adenomas at Kagoshima- and Hiroshima University hospitals in Japan. Ten (1.1%) patients were aged 80 years or older. We retrospectively assessed the clinical characteristics including preoperative comorbidities, manifestations, neuroimaging findings, and endocrinologic features of these ten patients. The subjects included eight males and two females. Their ages ranged from 80 to 86 with mean of 83.1 years. Of these, besides one case of growth hormone-producing adenoma, others were clinically nonfunctioning adenoma. Six patients had modest comorbidities such as hypertension, cardiovascular diseases, diabetes mellitus, or chronic kidney dysfunction, and all patients were classified into grade 2-3 on American Society of Anesthesiologists' Physical Status grading. Transsphenoidal surgery was performed in all due to visual disturbance in eight, diabetes mellitus as an intercurrent illness of acromegaly in one, and for the purpose of preventing visual disturbance in one patient who had an adenoma impinging optic chiasm but still had normal visual field. The surgeries provided sufficient decompression of the optic pathways and improved visual disorder in all. In an acromegalic male, his comorbidities considerably improved. No permanent surgical morbidity ensued. More than three axes of anterior pituitary hormones were preoperatively impaired in all, which were rarely recovered. Transsphenoidal surgery is safe and efficient treatment way for patients aged 80 years or older with pituitary adenomas with chiasmatic symptoms when the patients' general condition is well preserved and pituitary hormonal deficiency is adequately replaced.

    Background: An increasing number of elderly patients present with intracranial aneurysms. In addition to female gender, an older age is associated with a higher risk of developing a subarachnoid hemorrhage (SAH), and these patients often fare poorly in terms of long-term outcome. It is often thought that elderly patients would especially benefit from endovascular aneurysm treatment. We assessed the clinical outcomes in elderly patients with ruptured intracranial aneurysms (RIAs) who were treated by endovascular procedures. Methods: We performed a retrospective review of a prospective database of elderly patients treated with coil embolization for RIAs. The clinical outcomes were assessed using the modified Glasgow Outcome Scale. The rates of procedural complications and adverse events were also recorded. Results: During a period of 5 years, 162 patients with 183 intracranial aneurysms were treated in our hospital by means of an endovascular approach. Among them, 51 patients (31.5%) with a ruptured aneurysm were aged 70 years or older. These patients aged 70-91 years (mean age, 74 years) were treated by coil embolization for RIAs. Among them, seven had a Hunt and Hess (HH) grade of I or II, 42 had an HH grade of III or IV, and 2 had an HH grade of V. Endovascular treatment resulted in 32 complete occlusions (62.7%), 15 neck remnants (22%), and 4 body fillings (7.9%). Procedural complications occurred in five patients (9.8%). The outcomes were good or excellent in 17 patients (33.3%). Three patients (5.8%) who died had an HH grade of IV or V. Rebleeding occurred during follow-up in one patient (1.9%). Conclusions: Coil embolization of intracranial aneurysms is safe and effective in the elderly. However, the morbidity and mortality rates are higher in patients with high HH grades. This finding suggests that the timing of treatment should be based on the patient's initial clinical status. PMID:25101199

    ABSTRACT The introduction of pertussis vaccination in the United States (US) in the 1940s has greatly reduced its burden. However, the incidence of pertussis is difficult to quantify, as many cases are not laboratory-confirmed or reported, particularly in adults. This study estimated pertussis incidence in a commercially insured US population aged <50 years. Data were extracted from IMS' PharMetrics Plus claims database for patients with a diagnosis of pertussis or cough illness using International Classification of Diseases (ICD-9) codes, a commercial outpatient laboratory database for patients with a pertussis laboratory test, and the Centers for Disease Control influenza surveillance database. US national pertussis incidence was projected using 3 methods: (1) diagnosed pertussis, defined as a claim for pertussis (ICD-9 033.0, 033.9, 484.3) during 2008–2013; (2) based on proxy pertussis predictive logistic regression models; (3) using the fraction of cough illness (ICD-9 033.0, 033.9, 484.3, 786.2, 466.0, 466.1, 487.1) attributed to laboratory-confirmed pertussis, estimated by time series linear regression models. Method 1 gave a projected annual incidence of diagnosed pertussis of 9/100,000, which was highest in those aged <1 year. Method 2 gave an average annual projected incidence of 21/100,000. Method 3 gave an overall regression-estimated weighted annual incidence of pertussis of 649/100,000, approximately 58–93 times higher than method 1 depending on the year. These estimations, which are consistent with considerable underreporting of pertussis in people aged <50 years and provide further evidence that the majority of cases go undetected, especially with increasing age, may aid in the development of public health programs to reduce pertussis burden.

  20. Injuries from batteries among children aged <13 years--United States, 1995-2010.

    2012-08-31

    Injuries to children caused by batteries have been documented in the medical literature and by poison control centers for decades. Of particular concern is the ingestion of button batteries, especially those ≥20 mm in diameter (coin size), which can lodge in the esophagus, leading to serious complications or death. To estimate the number of nonfatal battery injuries among children aged <13 years, U.S. Consumer Product Safety Commission (CPSC) staff analyzed 1997-2010 data from the National Electronic Injury Surveillance System (NEISS). To identify fatal battery exposures, other CPSC databases covering 1995-2010 were examined, including the 1) Injury and Potential Injury Incident File; 2) Death Certificate Database (DTHS); and 3) In-Depth Investigation File (INDP). From 1997 to 2010, an estimated 40,400 children aged <13 years were treated in hospital emergency departments (EDs) for battery-related injuries, including confirmed or possible battery ingestions. Nearly three quarters of the injuries involved children aged ≤4 years; 10% required hospitalization. Battery type was reported for 69% of cases, and of those, button batteries were implicated in 58%. Fourteen fatal injuries were identified in children ranging in age from 7 months to 3 years during 1995-2010. Battery type was reported in 12 of these cases; all involved button batteries. CPSC is urging the electronics industry and battery manufacturers to develop warnings and industry standards to prevent serious injuries and deaths from button batteries. Additionally, public health and health-care providers can encourage parents to keep button batteries and products containing accessible button batteries (e.g., remote controls) away from young children.

    Human cortical folding is believed to correlate with cognitive functions. This likely correlation may have something to do with why abnormalities of cortical folding have been found in many neurodevelopmental disorders. However, little is known about how cortical gyrification, the cortical folding process, develops in the first 2 years of life, a period of dynamic and regionally heterogeneous cortex growth. In this article, we show how we developed a novel infant-specific method for mapping longitudinal development of local cortical gyrification in infants. By using this method, via 219 longitudinal 3T magnetic resonance imaging scans from 73 healthy infants, we systemically and quantitatively characterized for the first time the longitudinal cortical global gyrification index (GI) and local GI (LGI) development in the first 2 years of life. We found that the cortical GI had age-related and marked development, with 16.1% increase in the first year and 6.6% increase in the second year. We also found marked and regionally heterogeneous cortical LGI development in the first 2 years of life, with the high-growth regions located in the association cortex, whereas the low-growth regions located in sensorimotor, auditory, and visual cortices. Meanwhile, we also showed that LGI growth in most cortical regions was positively correlated with the brain volume growth, which is particularly significant in the prefrontal cortex in the first year. In addition, we observed gender differences in both cortical GIs and LGIs in the first 2 years, with the males having larger GIs than females at 2 years of age. This study provides valuable information on normal cortical folding development in infancy and early childhood. PMID:24647943

    Introduction Although the recommended optimal treatment of glioblastoma multiforme (GBM) is adjuvant chemoradiotherapy, trials in GBM have excluded patients older than 70 years. In this study, we aimed to assess overall survival (OS) and prognostic factors in elderly patients (≥ 70 years) with newly diagnosed GBM treated with radiotherapy (RT) ± concurrent/adjuvant temozolomide (TMZ). Material and methods Inclusion criteria were patients ≥ 70 years, pre-RT Karnofsky performance status (KPS) ≥ 60, and time between diagnosis and start of RT ≤ 2 months. A total of 40 patients aged ≥ 70 years, 12 female and 28 male, treated between January 2004 and December 2012, were evaluated. Median age was 73.5 years (range, 70–83 years). The median RT dose was 60 Gy (range, 30–62 Gy). Twenty-one (52.5%) received concurrent TMZ, and of those 12 (30%) went on to receive adjuvant TMZ. Results The median OS was 7 months (95% CI: 5.45–8.54). One- and two-year OS for the whole cohort was 38% and 16%, respectively. Sex, type of surgery, tumor size, and RT dose did not significantly affect the OS. Presence of concurrent TMZ (p < 0.005) and presence of adjuvant TMZ (p < 0.001) were associated with longer OS in our cohort. Conclusions RT ± TMZ seems to be a well-tolerated treatment in patients ≥ 70 years with GBM. Even though no superiority was found between conventional or hypofractionated RT regimens (p = 0.405), the addition of concurrent and adjuvant TMZ to RT increased the OS in our study.

    Introduction Although the recommended optimal treatment of glioblastoma multiforme (GBM) is adjuvant chemoradiotherapy, trials in GBM have excluded patients older than 70 years. In this study, we aimed to assess overall survival (OS) and prognostic factors in elderly patients (≥ 70 years) with newly diagnosed GBM treated with radiotherapy (RT) ± concurrent/adjuvant temozolomide (TMZ). Material and methods Inclusion criteria were patients ≥ 70 years, pre-RT Karnofsky performance status (KPS) ≥ 60, and time between diagnosis and start of RT ≤ 2 months. A total of 40 patients aged ≥ 70 years, 12 female and 28 male, treated between January 2004 and December 2012, were evaluated. Median age was 73.5 years (range, 70–83 years). The median RT dose was 60 Gy (range, 30–62 Gy). Twenty-one (52.5%) received concurrent TMZ, and of those 12 (30%) went on to receive adjuvant TMZ. Results The median OS was 7 months (95% CI: 5.45–8.54). One- and two-year OS for the whole cohort was 38% and 16%, respectively. Sex, type of surgery, tumor size, and RT dose did not significantly affect the OS. Presence of concurrent TMZ (p < 0.005) and presence of adjuvant TMZ (p < 0.001) were associated with longer OS in our cohort. Conclusions RT ± TMZ seems to be a well-tolerated treatment in patients ≥ 70 years with GBM. Even though no superiority was found between conventional or hypofractionated RT regimens (p = 0.405), the addition of concurrent and adjuvant TMZ to RT increased the OS in our study. PMID:27647990

    Background: The treatment of anterior cruciate ligament (ACL) injury consists of arthroscopic ACL reconstruction with patellar tendon or hamstring graft. Satisfactory results have been reported so far in the younger age group. Dilemma arises regarding the suitability of ACL reconstruction in patients aged 50 years and above. This retrospective analyses the outcome of ACL reconstruction in patients aged 50 years and above. Materials and Methods: 55 patients aged 50 years and above presented to our institution with symptomatic ACL tear and were managed with arthroscopic reconstruction with patellar tendon/hamstring graft. 22 patients underwent ACL reconstruction with bone- patellar tendon-bone graft and the remaining 33 with a hamstring graft. Evaluation of functional outcome was performed using International Knee Documentation Committee (IKDC) and Lysholm scoring in the preoperative period, at the end of 1 year and at the final followup. Radiographic evaluation was performed using the Kellgren–Lawrence grading system. Results: The mean preoperative IKDC score was 39.7 ± 3.3. At the end of 1-year following the operation, the mean IKDC score was 73.6 ± 4.9 and at the final followup was 67.8 ± 7.7. The mean preoperative Lysholm score was 40.4 ± 10.3. At the end of 1-year following the intervention, the mean Lysholm score was 89.7 ± 2.1 and at final followup was 85.3 ± 2.5. Overall, 14 out of 42 patients who underwent radiographic assessment showed progression of osteoarthritis changes at the final followup after the intervention. Conclusion: In our study, there was a statistically significant improvement in the IKDC and Lysholm scores following the intervention. There was a slight deterioration in the scores at the final followup but the overall rate of satisfaction was still high and most of the patients were able to do their routine chores and light exercises suitable for their age group. Around one-third of patients show progression of radiographic changes

    About 90% of all influenza-related deaths occur among people aged 65 years and older. Vaccination remains the primary option for preventing influenza infection. This study examined the efficacy of messages designed to increase the uptake of influenza vaccination. Two messages, narrative and didactic, were created based on the Extended Parallel Process Model (EPPM). The study employed a one-factor between-subjects experimental design with participants assigned randomly to three conditions: no message, didactic communication, and narrative communication. Participants were 311 Italian people aged 65 years or older. The results showed that, compared to no message and didactic communication, narrative communication was related to higher risk perception of influenza, to higher perception of the efficacy of the vaccine, and to self-efficacy related to vaccination, controlling for social trust, previous flu shot, and demographic variables. There were no differences among the three conditions with respect to the intention to receive the influenza vaccine. Findings suggest that narrative communication based on EPPM may have a persuasive effect on people aged 65 years or older.

    The ability to attribute different mental states to distinct individuals, or Theory of Mind (ToM), is widely believed to be developed mostly during preschool years. How different factors such as gender, number of siblings, or coarse personality traits affect this development is not entirely agreed upon. Here, we introduce a computerized version of the scaled ToM suite of tasks introduced by Wellman and Liu (2004), which allows us to meaningfully test ToM development on children 6 to 8-years old. We find that kids this age are still not entirely proficient in all ToM tasks, and continue to show a progression of performance with age. By testing this new age range, too, we are able to observe a significant advantage of girls over boys in ToM performance. Other factors such as number of siblings, birth order, and coarse personality traits show no significant relation with the ToM task results. Finally, we introduce a novel way to quantify the scaling property of the suite involving a sequence of set inclusions on one hand and a comparison between specially tailored sets of logistic models on the other. These measures confirm the validity of the scale in the 6- to 8-years old range.

    AIM: To investigate the safety and efficacy of peroral endoscopic myotomy (POEM) for achalasia in patients aged ≥ 65 years. METHODS: From November 2011 to August 2014, 15 consecutive patients (aged ≥ 65 years) diagnosed with achalasia were prospectively recruited and all underwent POEM at our institution. Eckardt score, lower esophageal sphincter (LES) pressure, esophageal diameter, SF-36 questionnaire, and procedure-related complications were used to evaluate the outcomes. RESULTS: All 15 patients were treated successfully by POEM, with a median operation time of 55 min. Median myotomy length was 10 cm. Three patients underwent circular myotomy and 12 full-thickness myotomies. Symptoms remitted in all cases during post-POEM follow-up of 6-39 mo. Eckardt score reduced significantly (pre-operation vs post-operation: 8.0 vs 1.0, P < 0.05). Median LES pressure decreased from 27.4 to 9.6 mmHg (P < 0.05). Median diameter of the esophagus was significantly decreased (pre-operation vs post-operation: 51.0 mm vs 30.0 mm, P < 0.05). Only one patient had reflux, which was resolved with oral proton pump inhibitors. No serious complications related to POEM were found. The quality of life of the 15 patients improved significantly after POEM. CONCLUSION: POEM is a safe and effective technique for treatment of achalasia in patients aged ≥ 65 years, with improvement in symptoms and quality of life. PMID:26290645

    OBJECTIVE: To determine the prevalence of vitamin A deficiency in children aged 6-9 years in northern Ethiopia. METHODS: A cross-sectional study was carried out and the data were analysed for 824 (61.5%) of 1339 eligible children for whom there was complete information on biochemical vitamin A status, dietary vitamin A intake, ocular examination for xerophthalmia, and anthropometry. FINDINGS: The prevalence of xerophthalmia was 5.8%; serum retinol levels were below 0.35 mumol/l and between 0.35 and 0.70 mumol/l in 8.4% and 51.1% of the children respectively. The liver vitamin A reserve (modified relative dose response ratio > or = 0.06) was low in 41.0% of the children. CONCLUSION: The high prevalence of severe vitamin A deficiency in children aged 6-9 years indicates the need to reevaluate the practice of targeting vitamin A supplementation programmes on children under 6 years of age in areas where vitamin A deficiency is endemic.

    The present study aimed at analysing the age-related decline in maximal muscle power (W) in 52 sedentary healthy women aged between 50 and 75 years to determine whether force or velocity is the major determinant. Maximal muscle power was estimated from two types of vertical jumps, squatting (SJ) and countermovement (CmJ), performed on a force platform. It was obtained by measuring the vertical force (F(opt)) applied to the body centre of gravity and calculating the corresponding vertical velocity (v(opt)). An age-related decline in absolute W was statistically significant in all the conditions examined and in both peak W and average power (W) values. The decrease in v(opt) was also statistically significant. Also F(opt) declined but this reduction was not statistically significant with the exception of the average value in CmJ. Not surprisingly the highest W were obtained in CmJ, and the difference in power production between the two types of jump showed an age-related decrement only in W. The main finding of the study was the demonstration that v(opt) was the critical determinant of the age-related decline in W in healthy elderly women.

    Objectives This paper discusses patterns of daily smokeless tobacco (SLT) use and correlates of poly SLT use among married women aged 18–40 years in a Mumbai slum community with implications for tobacco control. Methods Using a mixed methods approach, the study included a structured survey with 409 daily SLT users and in-depth interviews with 42 women. Participants for the survey were selected using a systematic sampling procedure (one woman in every fourth eligible household). Univariate and bivariate analysis, and multiple logistic regressions were conducted to identify demographic and social factors associated with women’s use of poly SLT products. To illustrate survey results, in-depth interviews were analyzed using Atlas ti software. Results Sixty-four percent of the women surveyed used only one type of SLT; of these, 30% used mishri, 32% used pan with tobacco and the rest used chewed tobacco (11%), gul (17%) or gutkha (10%). Thirty-six percent used more than one type of SLT. Poly SLT users chewed or rubbed 50% more tobacco as compared to single users (mean consumption of tobacco per day: 9.54 vs. 6.49 grams; p<0.001). Women were more likely to be poly SLT users if they were illiterate as compared to literate (adjusted odds ratio [AOR]=1.67; 95% confidence interval [CI]=1.07-2.71), if they had lived in Mumbai for 10 years or more, versus less than ten years (AOR=1.67, 95% CI=1.03-2.71); and if their husband was a poly SLT user as compared to a non SLT user (AOR=2.78, 95% CI=1.63-4.76). No differences were noted between pregnant and non-pregnant women in SLT consumption patterns. Conclusions Tobacco control policies and programs must focus specifically on both social context and use patterns to address SLT use among women of reproductive age with special attention to poly SLT users, an understudied and vulnerable population.

    2006-01-01

    Executive Summary Objective The objective of this analysis was to determine the strength of association between age, gender, ethnicity, family history of disease and refractive error and the risk of developing glaucoma or ARM? Clinical Need A routine eye exam serves a primary, secondary, and tertiary care role. In a primary care role, it allows contact with a doctor who can provide advice about eye care, which may reduce the incidence of eye disease and injury. In a secondary care role, it can via a case finding approach, diagnose persons with degenerative eye diseases such as glaucoma and or AMD, and lead to earlier treatment to slow the progression of the disease. Finally in a tertiary care role, it provides ongoing monitoring and treatment to those with diseases associated with vision loss. Glaucoma is a progressive degenerative disease of the optic nerve, which causes gradual loss of peripheral (side) vision, and in advanced disease states loss of central vision. Blindness may results if glaucoma is not diagnosed and managed. The prevalence of primary open angle glaucoma (POAG) ranges from 1.1% to 3.0% in Western populations, and from 4.2% to 8.8% in populations of African descent. It is estimated up to 50% of people with glaucoma are aware that they have the disease. In Canada, glaucoma disease is the second leading cause of blindness in people aged 50 years and older. Tonometry, inspection of the optic disc and perimetry are used concurrently by physicians and optometrists to make the diagnosis of glaucoma. In general, the evidence shows that treating people with increased IOP only, increased IOP and clinical signs of early glaucoma or with normal-tension glaucoma can reduce the progression of disease. Age-related maculopathy (ARM) is a degenerative disease of the macula, which is a part of the retina. Damage to the macula causes loss of central vision affecting the ability to read, recognize faces and to move about freely. ARM can be divided into an early

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

    Using data from National Health and Nutrition Examination Survey for the period 2003-2012, the objective of this study was to evaluate trends in blood lead levels (BLL) among adults aged 20-64 years (adults) and seniors aged ≥65 years (seniors). In addition, the contribution of other factors like gender, race/ethnicity, smoking, and exposure to secondhand smoke at home in explaining variability in BLL was also evaluated by fitting regression models with log10 transformed values of BLL as dependent variables. BLL decreased over 2003-2012 (p < 0.01). Irrespective of gender, race/ethnicity, and smoking status, seniors were found to have higher BLL than adults. Based on the magnitude of differences between the 5th and 95th percentiles, variability in the levels of blood lead was found to be substantially higher among seniors than among adults. Males had statistically significantly higher adjusted BLL than females (2.32 vs. 1.76 μg/dL for seniors, p < 0.01 and 1.66 vs. 1.13 μg/dL for adults, p < 0.01). Non-Hispanic whites had statistically significantly lower adjusted BLL than non-Hispanic blacks (1.99 vs. 2.42 μg/dL for seniors, p < 0.01 and 1.22 vs. 1.42 μg/dL for adults, p < 0.01). When compared with non-smokers, smokers had statistically significantly higher BLL (2.19 vs. 1.86 μg/dL for seniors, p < 0.01 and 1.54 vs. 1.22 μg/dL for adults, p < 0.01). Non-obese had statistically significantly higher BLL than obese individuals (2.11 vs. 1.93 μg/dL for seniors, p < 0.01 and 1.48 vs. 1.27 μg/dL for adults, p < 0.01). Exposure to secondhand smoke at home (SHS) was associated with statistically significantly higher BLL than when there was no exposure to SHS (β = 0.0683, p = 0.03 for seniors; β = 0.034, p = 0.034, p < 0.01 for adults).

    OBJECTIVE To clarify whether the increase in childhood type 1 diabetes is mirrored by a decrease in older age-groups, resulting in younger age at diagnosis. RESEARCH DESIGN AND METHODS We used data from two prospective research registers, the Swedish Childhood Diabetes Register, which included case subjects aged 0–14.9 years at diagnosis, and the Diabetes in Sweden Study, which included case subjects aged 15–34.9 years at diagnosis, covering birth cohorts between 1948 and 2007. The total database included 20,249 individuals with diabetes diagnosed between 1983 and 2007. Incidence rates over time were analyzed using Poisson regression models. RESULTS The overall yearly incidence rose to a peak of 42.3 per 100,000 person-years in male subjects aged 10–14 years and to a peak of 37.1 per 100,000 person-years in female subjects aged 5–9 years and decreased thereafter. There was a significant increase by calendar year in both sexes in the three age-groups <15 years; however, there were significant decreases in the older age-groups (25- to 29-years and 30- to 34-years age-groups). Poisson regression analyses showed that a cohort effect seemed to dominate over a time-period effect. CONCLUSIONS Twenty-five years of prospective nationwide incidence registration demonstrates a clear shift to younger age at onset rather than a uniform increase in incidence rates across all age-groups. The dominance of cohort effects over period effects suggests that exposures affecting young children may be responsible for the increasing incidence in the younger age-groups. PMID:21680725

    During April 25, 2014-October 15, 2015, approximately 99,000 residents of Flint, Michigan, were affected by changes in drinking water quality after their water source was switched from the Detroit Water Authority (DWA), sourced from Lake Huron, to the Flint Water System (FWS), sourced from the Flint River.* Because corrosion control was not used at the FWS water treatment plant, the levels of lead in Flint tap water increased over time. Adverse health effects are associated with lead exposure (1). On January 2, 2015, a water advisory was issued because of detection of high levels of trihalomethanes, byproducts of disinfectants.(†)(,)(§) Studies conducted by local and national investigators detected an increase in the prevalence of blood lead levels (BLLs) ≥5 µg/dL (the CDC reference level) among children aged <5 years living in Flint (2) and an increase in water lead levels after the water source switch (3). On October 16, 2015, the Flint water source was switched back to DWA, and residents were instructed to use filtered tap water for cooking and drinking. During that time, pregnant and breastfeeding women and children aged <6 years were advised to consume bottled water.(¶) To assess the impact on BLLs of consuming contaminated drinking water, CDC examined the distribution of BLLs ≥5 µg/dL among children aged <6 years before, during, and after the switch in water source. This analysis enabled determination of whether the odds of having BLLs ≥5 µg/dL before the switch differed from the odds during the switch to FWS (before and after the January 2, 2015, water advisory was issued), and after the switch back to DWA. Overall, among 9,422 blood lead tests in children aged <6 years, 284 (3.0%) BLLs were ≥5 µg/dL during April 25, 2013-March 16, 2016.

    The aim of this study was to clarify changes in the occurrence of misarticulations of dental consonants /r/, /s/ and /l/ between 6 and 8 years of age in cleft-affected Finnish children and to compare the effects of gender and to estimate if spacing due to changing of maxillary incisors could explain changes in articulation of these sounds. The subjects were 133 (47 girls, 86 boys) Finnish-speaking non-syndromic children with isolated cleft palate (n = 34), cleft lip/alveolus (n = 49), unilateral (n = 33), and bilateral (n = 17) cleft lip and palate. The results showed that there were no statistically significant differences between genders according to changes in articulation abilities by the age of 8 years. Eighty-one percent of the subjects with misarticulations at the age of 6 years still misarticulated at 8 years of age, and 16% of the subjects without misarticulations at the age of 6 years misarticulated at the age of 8 years; /s/ and /l/ misarticulations were eliminated more often than /r/ errors. New misarticulations were diagnosed at the age of 8 years in the same way in the groups with (14%) and without (16%) misarticulations at the age of 6 years. Dental arch spacing due to changing of maxillary incisors does not seem to explain new misarticulations of /r/, /s/ and /l/ sounds estimated at the age of 8 years.

    Background High television exposure time at young age has been described as a potential risk factor for developing behavioral problems. However, less is known about the effects of preschool television on subsequent bullying involvement. We examined the association between television viewing time through ages 2-5 and bullying involvement in the first grades of elementary school. We hypothesized that high television exposure increases the risk of bullying involvement. Method TV viewing time was assessed repeatedly in early childhood using parental report. To combine these repeated assessments we used latent class analysis. Four exposure classes were identified and labeled “low”, “mid-low”, “mid-high” and “high”. Bullying involvement was assessed by teacher questionnaire (n = 3423, mean age 6.8 years). Additionally, peer/self-report of bullying involvement was obtained using a peer nomination procedure (n = 1176, mean age 7.6 years). We examined child risk of being a bully, victim or a bully-victim (compared to being uninvolved in bullying). Results High television exposure class was associated with elevated risks of bullying and victimization. Also, in both teacher- and child-reported data, children in the high television exposure class were more likely to be a bully-victim (OR = 2.11, 95% CI: 1.42-3.13 and OR = 3.68, 95% CI: 1.75-7.74 respectively). However, all univariate effect estimates attenuated and were no longer statistically significant once adjusted for maternal and child covariates. Conclusions The association between television viewing time through ages 2-5 and bullying involvement in early elementary school is confounded by maternal and child socio-demographic characteristics.

    Purpose To determine whether stereopsis of infants treated for monocular cataracts varies with the type of optical correction used. Design Randomized prospective clinical trial Methods The Infant Aphakia Treatment Study randomized 114 patients with unilateral cataracts at age 1 to 7 months to either primary intraocular lens (IOL) or contact lens correction. At 4.5 years of age a masked examiner assessed stereopsis on these patients using three different tests: 1) Frisby; 2) Randot Preschool; and 3) Titmus fly. Results Twenty-eight patients (25%) had a positive response to at least one of the stereopsis tests. There was no statistically significant difference in stereopsis between the two treatment groups. Frisby (contact lens, 6 (11%); IOL, 7 (13%); p=0.99), Randot (contact lens, 3 (6%); IOL, 1 (2%); p=0.62) or Titmus: (contact lens, 8 (15%); IOL, 13 (23%); p=0.34). The median age at surgery for patients with stereopsis was younger than for those without stereopsis (1.2 versus 2.4 months; p=0.002). The median visual acuity for patients with stereopsis was better than for those without stereopsis (20/40 vs. 20/252; p=0.0003). Conclusion The type of optical correction did not influence stereopsis outcomes. However, two other factors did: age at surgery and visual acuity in the treated eye at age 4.5 years. Early surgery for unilateral congenital cataract and the presence of visual acuity better than or equal to 20/40 appear to be more important than the type of initial optical correction used for the development of stereopsis.

    Background/Objectives: Previous studies have demonstrated associations between some early-life exposures and later obesity, but most have used body mass index in childhood or adulthood as the outcome. The objective of this study was to investigate whether early-life exposures were associated with directly measured fat and lean mass in adolescence. Subjects/Methods: This study used data on 4750 mother–offspring pairs, collected as a part of the Avon Longitudinal Study of Parents and Children, Bristol, UK between 1991 and 1992; associations between behavioural exposures occurring from conception up to 5 years of age (maternal and paternal smoking during pregnancy, breastfeeding, age at introduction to solids, dietary patterns and physical inactivity during early childhood) and offspring body composition measured by dual-energy X-ray absorptiometry at ~15 years were assessed. Results: After full adjustment for potential confounders, maternal smoking during pregnancy, having a junk food diet and spending more time watching television in early childhood were all associated with higher fat mass at age 15, whereas maternal smoking, having a healthy diet and playing computer games more frequently in early childhood were all associated with a higher lean mass at age 15. Associations with paternal smoking were generally weaker for both fat and lean mass, but as there was no strong statistical evidence for maternal vs paternal differences, confounding by social factors rather than a direct effect of maternal smoking cannot be ruled out. Early feeding was not associated with fat or lean mass at age 15. Conclusions: This study does not provide compelling evidence for associations between most early-life factors and body composition in adolescence. However, possible associations with dietary patterns and physical inactivity in early childhood require further investigation in other cohorts that have direct measurements of adolescent body composition.

    To test the hypothesis that characteristics of perinatal infection are associated with long-term cognitive limitations among preterm infants, we analyzed data from 294 infants (142 females, 152 males) < or = 1500 g birthweight and <37 completed weeks of gestation who were examined at age 9 years. We identified 47 children (20 females, 27 males) who had a non-verbal Kaufman Assessment Battery for Children (K-ABC) scale standard value below 70, i.e. more than 2 SDs below the age-adjusted mean. The 247 children (122 females, 125 males) with a score > or = 70 served as control participants. Maternal nationality and education, and low gestational age were significantly associated with a K-ABC non-verbal standard value <70. Both neonatal brain damage (intraventricular hemorrhage) and long-term sequelae (cerebral palsy [CP], diagnosed at age 6 years) were significantly associated with a below-normal non-verbal K-ABC score. Maternal fever at birth was present in five cases (11%) and eight controls (3%; odds ratio 3.6, 95% confidence interval 1.1 to 11.4). Clinical chorioamnionitis and preterm labor and/or premature rupture of membranes (as opposed to toxemia and other initiators of preterm delivery) were also more common among cases than control participants. When adjusting for potential confounders such as gestational age, maternal education and nationality, and CP, the risk estimate for maternal fever remained unchanged (3.8, 0.97 to 14.6). We conclude that perinatal infection might indeed contribute to an increased risk for long-term cognitive deficits in preterm infants. PMID:12613769

    Suicide is the second leading cause of death among persons aged 10-24 years in the United States and accounted for 5,178 deaths in this age group in 2012. Firearm, suffocation (including hanging), and poisoning (including drug overdose) are the three most common mechanisms of suicide in the United States. Previous reports have noted that trends in suicide rates vary by mechanism and by age group in the United States, with increasing rates of suffocation suicides among young persons. To test whether this increase is continuing and to determine whether it varies by demographic subgroups among persons aged 10-24 years, CDC analyzed National Vital Statistics System mortality data for the period 1994-2012. Trends in suicide rates were examined by sex, age group, race/ethnicity, region of residence, and mechanism of suicide. Results of the analysis indicated that, during 1994-2012, suicide rates by suffocation increased, on average, by 6.7% and 2.2% annually for females and males, respectively. Increases in suffocation suicide rates occurred across demographic and geographic subgroups during this period. Clinicians, hotline staff and others who work with young persons need to be aware of current trends in suffocation suicides in this group so that they can accurately assess risk and educate families. Media coverage of suicide incidents and clusters should follow established guidelines to avoid exacerbating risk for "suicide contagion" among vulnerable young persons.* Suicide contagion is a process by which exposure to the suicide or suicidal behavior of one or more persons influences others who are already vulnerable and thinking about suicide to attempt or die by suicide. Early prevention strategies are needed to reduce the likelihood of young persons developing suicidal thoughts and behavior.

    Introduction 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. Methods 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. Results 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. Conclusion 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. PMID:23597395

    The risk of serious head injury (HI) from a fall in a young child is ill defined. The relationship between the object fallen from and prevalence of intracranial injury (ICI) or skull fracture is described. Method Cross-sectional study of HIs from falls in children (<6 years) admitted to UK hospitals, analysed according to the object fallen from and associated Glasgow Coma Score (GCS) or alert, voice, pain, unresponsive (AVPU) and CT scan results. Results Of 1775 cases ascertained (median age 18 months, 54.7% boys), 87% (1552) had a GCS=15/AVPU=alert. 19.3% (342) had a CT scan: 32% (110/342) were abnormal; equivalent to 5.9% of the overall population, 16.9% (58) had isolated skull fractures and 13.7% (47) had ICI (49% (23/47) had an associated skull fracture). The prevalence of ICI increased with neurological compromise; however, 12% of children with a GCS=15/AVPU=alert had ICI. When compared to falls from standing, falls from a person's arms (233 children (mean age 1 year)) had a significant relative OR for a skull fracture/ICI of 6.94 (95% CI 3.54 to 13.6), falls from a building (eg, window or attic) (mean age 3 years) OR 6.84 (95% CI 2.65 to 17.6) and from an infant or child product (mean age 21 months) OR 2.75 (95% CI 1.36 to 5.65). Conclusions Most HIs from a fall in these children admitted to hospital were minor. Infants, dropped from a carer's arms, those who fell from infant products, a window, wall or from an attic had the greatest chance of ICI or skull fracture. These data inform prevention and the assessment of the likelihood of serious injury when the object fallen from is known. PMID:26297697

    Introduction and objective The growing population of the elderly, as well as the occurrence of coexisting diseases and polypharmacy, is the reason why diseases of patients aged $65 years belong to the major issues of the contemporary medicine. Among the most frequent diseases of the elderly, there are respiratory system diseases. They are difficult to diagnose because of the patient group specificity, which is the reason for increased mortality among seniors, caused by underdiagnosis. The study objective was to assess the factors influencing spirometry results in hospitalized patients aged ≥65 years with respiratory system disorders. Material and methods In the research, 217 (100%) patients aged ≥65 years who underwent spirometry at the Regional Medical Center of the Jelenia Góra Valley Hospital in Poland were analyzed. In the statistical analysis, the STATISTICA 9.1 program, the t-test, the Shapiro–Wilk test, the ANOVA test, and the Scheffé’s test were applied. Results The majority of the patients (59.4%) were treated in the hospital. The most frequent diagnosis was malignant neoplasm (18%). The study showed a statistically significant dependence between the forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC parameters and the time of hospitalization, as well as between the FVC and FEV1 parameters and the age of patients. The FVC parameter values turned out to be dependent on the main diagnosis. Highest results were noted in patients with the diagnosis of sleep apnea or benign neoplasm. A low FVC index can reflect restrictive ventilation defects, which was supported by the performed analyses. Highest FEV1/FVC values were observed in nonsmokers, which confirms the influence of nicotine addiction on the incidence of respiratory system diseases. Conclusion The respondents’ sex and the established diagnosis statistically significantly influenced the FVC index result, and the diet influenced the FEV1/FVC parameter result

    Abstract Objective: To compare the functional performance of students diagnosed with developmental delay (DD) up to two years of age with peers exhibiting typical development. Methods: Cross-sectional study with functional performance assessment of children diagnosed with DD up to two years of age compared to those with typical development at seven to eight years of age. Each group consisted of 45 children, selected by non-random sampling, evaluated for motor skills, quality of home environment, school participation and performance. ANOVA and the Binomial test for two proportions were used to assess differences between groups. Results: The group with DD had lower motor skills when compared to the typical group. While 66.7% of children in the typical group showed adequate school participation, receiving aid in cognitive and behavioral tasks similar to that offered to other children at the same level, only 22.2% of children with DD showed the same performance. Although 53.3% of the children with DD achieved an academic performance expected for the school level, there were limitations in some activities. Only two indicators of family environment, diversity and activities with parents at home, showed statistically significant difference between the groups, with advantage being shown for the typical group. Conclusions: Children with DD have persistent difficulties at school age, with motor deficit, restrictions in school activity performance and low participation in the school context, as well as significantly lower functional performance when compared to children without DD. A systematic monitoring of this population is recommended to identify needs and minimize future problems. PMID:26553573

    Summary To find an association between smoking and the development of myocardial infarction in male patients above forty years of age presenting at the echocardiology department of Sudan heart center Khartoum. A prospective cohort study was carried out at the echocardiography department of Sudan Heart Center in Khartoum-Sudan between July 2012 and June 2014. The study population comprised a total of 168 adult male patients who underwent cardiac ultrasound scanning. Out of a total of 144 cases, 65% (94) of patients were smokers, 74% of the 94 cases smoked for more than 10 years, and 26% of the 94 cases smoked for less than 10 years. With this study it was concluded that smoking is a risk factor for the development of myocardial infarction. This study showed that patients with myocardial infarction are more likely to have a past history of smoking. PMID:27081418

    Little information is available concerning early specialization and competitive success in judo across the early training years. Thus, the present objective was to verify the stability of individual competitive performance of a state-level championship for judo athletes who had been previously successful. For this, 406 athletes from six age groups (9 to 20+ years old) of each sex were followed for 10 years. Using recorded data from the São Paulo State Judo Federation beginning in 1999, the scores and standings for these judo players were analyzed. The proportion of medal winners during this period was not constant, differing from the grand mean in all groups of both 204 males and 202 females. At the end of this period, only 7% of the male and 5% of the female athletes had maintained their competitive levels. Successful competitive performance in early judo competition was not associated with success later in adulthood. PMID:21987915

    We hypothesize that the time when age-related changes in autonomic functioning and in sleep structure occur are different and that autonomic functioning modulates sleep architecture differently before and after 50 years of age. Sixty-eight healthy subjects (aged 20 to 79 years old, 49 of them women) were enrolled. Correlation analysis revealed that wake after sleep onset, the absolute and relative value of stage 1 (S1; S1%), and relative value of stage 2 (S2) were positively correlated with age; however, sleep efficiency, stage 3 (S3), S3%, and rapid-eye-movement latency (REML) were negatively correlated with age. Significant degenerations of sleep during normal aging were occurred after 50 years of age; however, significant declines of autonomic activity were showed before 50 years of age. Before 50 years of age, vagal function during sleep was negatively correlated with arousal index; however, after 50 years of age, it was positively correlated with S1 and S1%. In addition, sympathetic activity during wake stage was positively related to S2% only after 50 years of age. Our results imply that the age-related changes in autonomic functioning decline promptly as individuals leave the younger part of their adult life span and that age-related changes in sleep slowly develop as individuals enter the older part of their adult life span. Furthermore, while various aspects of sleep architecture are modulated by both the sympathetic and vagal nervous systems during adult life span, the sleep quality is mainly correlated with the sympathetic division after 50 years of age.

    The medical records of all children less than 1 year of age presenting to the Accident and Emergency Department over a 5-year period (1995-1999) with a fracture were retrospectively reviewed for possible abuse. Seventy-four children presented with fractures during the study period, with a mean age at presentation of 5 months (range 2 weeks to 1 year). Of these children, 46 had skull fractures and 28 had long bone fractures. Children were classified into one of seven categories: definite abuse, likely abuse, suspicious, likely accident, definite accident, neglect, or unknown cause. A three-tier system of grading for possible abuse was then used to analyze variance. The first tier consisted of the initial assessment by staff clinicians, the second retrospectively by an orthopaedic registrar, and the third retrospectively by a designated doctor in child protection (consultant pediatrician), all using the same information from the case notes. The use of the three-tier system of grading demonstrated a variance in the diagnosis of nonaccidental injury. The possibility of abuse was underestimated at the time of the original injury in over a quarter of cases (28.4%) when compared with the assessment by the consultant pediatrician. In 34 children (46%), there was no written documentation that nonaccidental injury was ever considered. While management depends on local guidelines and arrangements, the authors would advise that all children under 1 year of age with a fracture should be admitted to the hospital and referred to a pediatrician for child protection assessment.

    Purpose: To review the outcomes and tolerability of full-dose chemoradiation in elderly patients aged 75 years or older with localized pancreatic cancer. Methods and Materials: We retrospectively reviewed patients aged 75 years or older with nonmetastatic pancreatic cancer treated with chemoradiation therapy at two institutions from 2002 to 2007. Patients were analyzed for treatment toxicity, local recurrences, distant metastases, and survival. Results: A total of 42 patients with a median age of 78 years (range, 75-90 years) who received chemoradiation therapy for pancreatic cancer were identified. Of the patients, 24 had locally advanced disease treated with definitive chemoradiation, and 18 had disease treated with surgery and chemoradiation. Before chemoradiotherapy, the mean Eastern Cooperative Oncology Group performance status was 1.0 {+-} 0.8, and the mean 6-month weight loss was 5.3 {+-} 3.8 kg. The mean radiation dose delivered was 48.1 {+-} 9.2 Gy. All patients received fluoropyrimidine-based chemotherapy concurrently with radiotherapy. In all, 8 patients (19%) were hospitalized, 7 (17%) had an emergency room visit, 15 (36%) required a radiation treatment break, 3 (7%) required a chemotherapy break, 9 (21%) did not complete therapy, and 22 (49%) had at least one of these adverse events. The most common toxicities were nausea, pain, and failure to thrive. Median overall survival was 8.6 months (95% confidence interval, 7.2-13.1) in patients who received definitive chemoradiation therapy and 20.6 months (95% confidence interval, 9.5-{infinity}) in patients who underwent resection and chemoradiation therapy. Conclusions: In this dataset of very elderly patients with pancreatic cancer and good Eastern Cooperative Oncology Group performance status, outcomes after chemoradiotherapy were similar to those among historic controls for patients with locally advanced and resected pancreatic cancer, although many patients experienced substantial treatment

    Background A method for assessing dental maturity in different populations was first developed in 1973 by Demirjian and has been widely used and accepted since then. While the accuracy for evaluating dental age using Demirjian’s method compared to children’s chronological age has been extensively studied in recent years, the results currently available remain controversial and ambiguous. Methods A literature search of PubMed, Embase, Web of Science, CNKI and CBM databases was conducted to identify all eligible studies published before July 12th, 2013. Weighted mean difference (WMD) with corresponding 95% confidence interval (95% CI) was used to evaluate the applicability of Demirjian’s method for estimating chronological age in children. Results: A meta-analysis was conducted on 26 studies with a total of 11,499 children (5,301 boys and 6,198 girls) aged 3.5 to 16.9 years. Overall, we found that Demirjian’s method overestimated dental age by 0.35 (4.2 months) and 0.39 (4.68 months) years in males and females, respectively. A subgroup analysis by age revealed that boys and girls between the ages of 5 to 14 were given a dental age estimate that was significantly more advanced than their chronological age. Differences between underestimated dental ages and actual chronological ages were lower for male and female 15- and 16-year-old subgroups, though a significant difference was found in the 16-year-old subgroup. Conclusions Demirjian’s method’s overestimation of actual chronological tooth age reveals the need for population-specific standards to better estimate the rate of human dental maturation.

    Acquisition of time knowledge (TK; the correct representation and use of time units) is linked to the development of numerical abilities, but this relationship has not been investigated in children. The current study examined the acquisition of TK and its association with numerical skills. A total of 105 children aged 6 to 11 years were interviewed with our Time Knowledge Questionnaire (TKQ), developed for purposes of this study, and the Zareki-R, a battery for the evaluation of number processing and mental calculation. The TKQ assessed conventional time knowledge (temporal orientation, temporal sequences, relationships between time units, and telling the time on a clock), estimation of longer durations related to birthday and life span, and estimation of the duration of the interview. Time knowledge increased with age, especially from 6 to 8 years, and was strongly linked to numerical skills. Regression analyses showed that four numerical components were implicated in TK: academic knowledge of numbers and number facts (e.g., reading Arabic numerals, mental calculation), number line estimation (e.g., correspondence between a number and a distance), contextual estimation (e.g., many/few leaves on a tree, children in a family), and numerical tasks involving verbal working memory (e.g., comparison of numbers presented orally). Numerical correlations with TK varied according to children's age; subtests based on academic knowledge of numbers, working memory, and number line estimation were linked with TK in the younger children, but only contextual estimation was associated with TK in the older children.

  17. Nonfatal bathroom injuries among persons aged ≥15 years--United States, 2008.

    PubMed

    2011-06-10

    In 2008, approximately 21.8 million persons aged ≥15 years sustained nonfatal, unintentional injuries, resulting in approximately $67.3 billion in lifetime medical costs. Information about where injuries occur is limited, but bathrooms commonly are believed to be a particularly hazardous location. To investigate this assumption, CDC analyzed data from a nationally representative sample of emergency departments (EDs) to describe the incidence and circumstances of nonfatal injuries in bathrooms (in any setting) among persons aged ≥15 years in the United States. This report describes the results of that investigation, which found that, based on 3,339 cases documented in the 2008 National Electronic Surveillance System All Injury Program (NEISS-AIP) database, an estimated 234,094 nonfatal bathroom injuries were treated in U.S. EDs. Injury rates increased with age, and most injuries (81.1%) were caused by falls. All persons, but especially older adults, should be aware of bathroom activities that are associated with a high risk for injury and of environmental modifications that might reduce that risk.

    Abstract Objective: to estimate the prevalence and factors associated with preoperative anxiety in children who wait for outpatient surgery. Method: cross-sectional analysis of baseline data of a prospective cohort study that investigates the predictors of postoperative pain in children aged 5-12 years submitted to inguinal and umbilical hernia repair. It was selected 210 children, which were interviewed in the preoperative holding area of a general hospital. Anxiety was evaluated using the modified Yale Preoperative Anxiety Scale (mYPAS). Sociodemographic and clinical variables were analyzed as exposure and anxiety (mYPAS final score>30) as outcome. Logistic regression was used to identify factors associated with preoperative anxiety. Results: forty-two percent (42.0%) of children presented preoperative anxiety (CI95%: 35.7%-48.6%), with mean scores equal to 30.1 (SD=8.4). Factors associated with preoperative anxiety were: age group of 5-6 years (OR=2.28; p=0.007) and socioeconomic status classified as class C (OR=2.39; p=0.016). Conclusion: the evaluation of children who wait for outpatient surgery should be multidimensional and comprise information on age and socioeconomic status, in order to help in the identification and early treatment of preoperative anxiety.

    We examined stability, change, and dedifferentiation of well-being in 124 participants with a baseline age between 87 and 97 years (M = 90.56, SD = 2.92) across 7 measurement occasions over 4 years. Measures of hedonic (life satisfaction, positive affect and negative affect) and eudaimonic well-being (autonomy, purpose in life, self-acceptance, environmental mastery), as well as indicators of mental distress (depressive symptoms, attitudes toward death and dying, disease phobia) were included. Average levels indicated high well-being at all measurement occasions in the majority of indicators analyzed. However, mean numbers of depressive symptoms were close to the cutoff point of clinical depression. Analyses of intra-individual correlations revealed high loadings of depressive symptoms, positive affect, and environmental mastery on a common factor. However, several well-being indicators were not substantially interrelated on the intra-individual level, suggesting their trajectories were rather independent of each other. Acceptance of death and dying was surprisingly high and even increased, whereas mean levels in fear of death were very low and declined over time. Overall, our findings do not suggest late-life dedifferentiation of well-being trajectories in very-old age. Our results rather support the need to consider indicators of hedonic and eudaimonic well-being, as well as mental distress, to understand the multifaceted and multidirectional dynamics of well-being in very-old age.

    The objective of this study was to determine the epidemiological and clinical features of rotavirus infection among children aged less than 5 years in rural southern Ethiopia. We conducted a hospital-based, prospective study among children aged less than 5 years with acute diarrhea and moderate to severe dehydration attending the outpatient department of Gambo Rural Hospital, Ethiopia during September-November 2012. Three hundred fourteen children were included in the study, of whom 137 (43.6%) had rotavirus infection. The average age of children with rotavirus infection was lower than those without it [odds ratio (OR): 0.94]. Finding severe dehydration on skin pinch test (adjusted OR: 3.76) and having diarrhea for !3 days (adjusted OR: 2.50) were associated with rotavirus infection. The mortality rate was 4.4% among rotavirus infection children and 0% among non-rotavirus diarrhea cases (p=0.006). Rotavirus infection should be suspected in children with severe dehydration on a skin pinch test and among those presenting with diarrhea for 3 days in rural southern Ethiopia. PMID:26521516

    Spirometry is the most important tool in diagnosing pulmonary disease and is the most frequently performed pulmonary function test. Since respiratory disease is the single greatest cause for morbidity and mortality on the Navajo Nation, the purpose of this study was to create new age and race-specific pulmonary nomograms for Navajo children. Five hundred fifty-eight healthy children, ages 6-14 years, attending Navajo Nation elementary schools in Arizona, were asked to perform spirometry to develop population-specific and tribe-specific nomograms for forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), and FEV1 Ratio (FEV1/FVC). Spirometry tests from 284 girls and 274 boys met American Thoracic Society quality control standards. Lung function values, except for FEV1/FVC, all increased with height. The lower limit of the normal range for FEV1/FVC was 80%. The spirometry reference equations from the healthy boys and girls were developed. Height and the natural log of height were significant predictors of FEV1, FVC, and FEF(25-75%) in the gender-specific models. The resulting population-specific spirometry reference equations should be used when testing Navajo children ages 6-14 years. However, the use of the NHANES III spirometry reference equations for Caucasian children may not result in significant misclassification in clinical settings providing that a maximal effort is given by the Navajo child being tested.

    Recent evidence suggests that emotional well-being improves from early adulthood to old age. This study used experience-sampling to examine the developmental course of emotional experience in a representative sample of adults spanning early to very late adulthood. Participants (N = 184, Wave 1; N = 191, Wave 2; N = 178, Wave 3) reported their emotional states at five randomly selected times each day for a one week period. Using a measurement burst design, the one-week sampling procedure was repeated five and then ten years later. Cross-sectional and growth curve analyses indicate that aging is associated with more positive overall emotional well-being, with greater emotional stability and with more complexity (as evidenced by greater co-occurrence of positive and negative emotions). These findings remained robust after accounting for other variables that may be related to emotional experience (personality, verbal fluency, physical health, and demographic variables). Finally, emotional experience predicted mortality; controlling for age, sex, and ethnicity, individuals who experienced relatively more positive than negative emotions in everyday life were more likely to have survived over a 13 year period. Findings are discussed in the theoretical context of socioemotional selectivity theory.

    The study identified the common aetiological agents and prominent clinical features of dysentery cases in children aged <5 years and compared this to non-dysentery diarrhoeal cases from the same population. From January 2010 to December 2011, 2324 children aged <5 years received treatment at Kumudini Hospital, of which 682 (29%) presented with dysentery. Of the dysenteric children, aetiology could not be determined for over half (61%). Shigella spp. accounted for 32% of dysentery cases. Significant associations were found between presence of blood in stool and: child age (24-59 months) [odds ratio (OR) 2.21, 95% confidence interval (CI) 1.49-3.27], no treatment of drinking water at home (OR 2.00, 95% CI 1.09-3.67), vomiting (OR 0.19, 95% CI 0.14-0.25), abdominal pain (OR 4.68, 95% CI 3.24-6.77), straining (OR 16.45, 95% CI 11.92-22.69), wasting (OR 1.66, 95% CI 1.15-2.41), and presence of Shigella in stool (OR 6.25, 95% CI 4.20-9.29) after controlling for confounders. This study makes it clear that appropriate public health strategies are needed to reduce the burden of dysentery in Bangladesh.

    A health survey of 6946 50-to-59 year-old women of TOPS, an organization for weight reduction, was used to study the natural history of obesity. Weight history was compared for four groups of women divided on the basis of their per cent above ideal body weight (IBW) in their 50s (less than 20%, 20-49%, 50-99% and 100+%). In each of the four groups, the majority of women were not obese by age 20. Sixteen per cent of the women who were 100+% overweight in their 50s were not obese at anytime during their first 30 years of life. Thirty-six per cent of the women who were 50-99% about IBW were not overweight at anytime prior to their 30th birthday. The history of obesity prior to age 30 was not associated with weight gain between the ages of 30 and 50. These data suggest: 1) than there is no critical time for the development of obesity, and 2) that previous weight history is not a dominant factor in determining subsequent weight gain. PMID:7361956

    This article examines the association between mental health disorders and being identified as a bully among children between the ages of 6 and 17 years. Data from the 2007 National Survey of Children's Health were examined. A total of 63,997 children had data for both parental reported mental health and bullying status. Bivariate analysis and logistic regression was performed to assess the association between mental health status and being identified as a bully with an age-stratified analysis and sub-analysis by type of mental health disorder. In 2007, 15.2% of U.S. children ages 6 to 17 years were identified as bullies by their parent or guardian. Children with a diagnosis of depression, anxiety, or depression had a threefold increased odds of being a bully. The diagnosis of depression is associated with a 3.31 increased odds (95% CI = [2.7, 4.07]) of being identified as a bully. Children with anxiety and attention deficit and hyperactivity disorder (ADHD) had similar odds. The diagnosis of a mental health disorder is strongly associated with being identified as a bully. In particular, depression, anxiety, and ADHD are strongly associated with being identified as a bully. These findings emphasize the importance of providing psychological support to not only victims of bullying but bullies as well. Understanding the risk profile of childhood bullies is essential in gaining a better grasp of this public health problem and in creating useful and appropriate resources and interventions to decrease bullying.

  9. Subjective and Objective Memory Changes in Old Age across Five Years.

    Typically, subjective memory assessments (be it in form of single items or questionnaires) in old age only weakly correlate with the performance in objective memory tests at cross-section. It thus appears as if individual differences in subjective memory assessments hardly reflect individual differences in memory in old age. A shortcoming of cross-sectional studies, however, is that subjective assessments may rely on different individual standards, which are not taken into account. One solution to this problem has been to investigate subjective and objective memory longitudinally, thereby focusing on individual differences in intraindividual changes. Results from studies using this approach have been mixed, with some studies showing a significantly stronger relation between changes than between levels, and other studies showing no such significant difference. Using data from the Zurich Longitudinal Study on Cognitive Aging (n=236), we find that 5-year changes in subjective assessments of memory capacity and memory changes correlate with objective memory changes of 0.54 and -0.44, respectively. These correlations are significantly stronger than at cross-section. After controlling for age, depressive affect, and subjective health at the first measurement occasion, correlations are slightly attenuated, but the basic findings remain the same. PMID:25791780

    Corneal thickness (CT) maps of the central (2-mm diameter), para-central (2 to 5-mm diameter), peripheral (5 to 6-mm diameter), and minimum (5-mm diameter) cornea were measured in normal Chinese school children aged 7 to 15 years old using Fourier-domain optical coherence tomography. Multiple regression analyses were performed to explore the effect of associated factors [age, gender, refraction, axial length and corneal curvature radius (CCR)] on CT and the relationship between central corneal thickness (CCT) and intraocular pressure (IOP). A total of 1228 eyes from 614 children were analyzed. The average CCT was 532.96 ± 28.33 μm for right eyes and 532.70 ±28.45 μm for left eyes. With a 10 μm increase in CCT, the IOP was elevated by 0.37 mm Hg, as measured by noncontact tonometry. The CT increased gradually from the center to the periphery. The superior and superior nasal regions had the thickest CTs, while the thinnest points were primarily located in the inferior temporal cornea. The CCT was associated with CCR (p = 0.008) but not with gender (p = 0.075), age (p = 0.286), axial length (p = 0.405), or refraction (p = 0.985). In the para-central region and the peripheral cornea, increased CT was associated with younger age, male gender, and a flatter cornea. PMID:26751798

    The rising abundances of greenhouse gases in the atmosphere is associated with an increase in radiative forcing that leads to warming of the troposphere, the lower portion of the Earth's atmosphere, and cooling of the stratosphere above. A secondary effect of increasing levels of greenhouse gases is a possible change in the stratospheric circulation, which could significantly affect chlorofluorocarbon lifetimes, ozone levels and the climate system more generally. Model simulations have shown that the mean age of stratospheric air is a good indicator of the strength of the residual circulation, and that this mean age is expected to decrease with rising levels of greenhouse gases in the atmosphere. Here we use balloon-borne measurements of stratospheric trace gases over the past 30years to derive the mean age of air from sulphur hexafluoride (SF6) and CO2 mixing ratios. In contrast to the models, these observations do not show a decrease in mean age with time. If models are to make valid predictions of future stratospheric ozone levels, and of the coupling between ozone and climate change, a correct description of stratospheric transport and possible changes in the transport pathways are necessary.

    The purpose of the study is to describe the values and distribution of corneal epithelium thickness (CET) in normal Chinese school-aged children, and to explore associated factors with CET. CET maps were measured by Fourier-domain optical coherence tomography (FD-OCT) in normal Chinese children aged 7 to 15 years old from two randomly selected schools in Shanghai, China. Children with normal intraocular pressure were further examined for cycloplegic autorefraction, corneal curvature radius (CCR) and axial length. Central (2-mm diameter area), para-central (2- to 5-mm diameter area), and peripheral (5- to 6-mm diameter area) CET in the superior, superotemporal, temporal, inferotemporal, inferior, inferonasal, nasal, superonasal cornea; minimum, maximum, range, and standard deviation of CET within the 5-mm diameter area were recorded. The CET was thinner in the superior than in the inferior and was thinner in the temporal than in the nasal. The maximum CET was located in the inferior zone, and the minimum CET was in the superior zone. A thicker central CET was associated with male gender (p = 0.009) and older age (p = 0.037) but not with CCR (p = 0.061), axial length (p = 0.253), or refraction (p = 0.351) in the multiple regression analyses. CCR, age, and gender were correlated with para-central and peripheral CET. PMID:27004973

    In Canadian Provinces and in several states of the United States the minimal legal age to drive a motor vehicle is 16 years old and in some, it is 15. The excess mortality and morbidity registered by 15 to 24-year-old drivers is well known. Several studies have reported that accident rates decrease with experience, but the effect of the age of new drivers has not been well documented. The objective is to study injury accident rates in terms of the age and experience factors. The data sources are computer files of the Government Insurance Corporation (Société de l'assurance automobile du Québec), which covers all Quebec drivers. For each driver, the file contains birth date, sex, year and month of first license, involvement in accidents, and other parameters. The yearly rates (1970-1984) of new permits per age last birthday and sex show an increase over time, particularly for 16-year-old men. For the period 1979-1984, injury accident involvement rates were computed for all Quebec drivers by age, sex, and driving experience. An experienced driver has been defined as a person who has been licensed for at least one year. The results show, for experienced as well as inexperienced young men (16-18), a high injury accident rate that decreases with age. For women, the rates are much lower and decrease more gradually than for men. This study does not take into account the kilometers driven. Since young drivers (16-18) have the highest accident rates, the question of regulating access to first licensing for such drivers must be examined as a possible strategy for injury prevention.

    The objective of our study was to identify the causes of death in children <15 years of age in Inner Mongolia and to examine the age-specific causes of death. Study data from 2008–2012 were obtained from the Death Registry System that is maintained by the Inner Mongolia Centers for Disease Control and Prevention. The mortality rate (per 100,000) for children <15 years of age was calculated and stratified by age in different years. We computed the proportion of age-specific causes of death for children <15 years that occurred between 2008 and 2012 across eight monitoring points in Inner Mongolia. We used a log-linear model to analyze the year and age effects on childhood mortality. From 2008-2012, the standardized mortality of children <15 years of age was 42.78/100,000. The mortality rate was not significantly different from 2008 to 2012 (p>0.05); the mortality rate was the highest in the <1-year age group (p<0.05); and the mortality rate of the <1-year age group was higher in 2012 compared to that in 2009 (p<0.05), 2010 (p<0.05), and 2011 (p<0.05). In children aged 1-14 years, the leading cause of death was injuries, among which transport accident injuries were the most prevalent. To reduce the childhood mortality rate in Inner Mongolia, China, we should focus on the prevention of perinatal deaths in infants <1 year of age and on the prevention of transport accident injuries among older children (1-14 years).

    OBJECTIVE To analyze if the nutritional status of children aged less than five years is related to the biological conditions of their mothers, environmental and socioeconomic factors, and access to health services and social programs. METHODS This cross-sectional population-based study analyzed 664 mothers and 790 children using canonical correlation analysis. Dependent variables were characteristics of the children (weight/age, height/age, BMI/age, hemoglobin, and retinol serum levels). Independent variables were those related to the mothers’ nutritional status (BMI, hemoglobin, and retinol serum levels), age, environmental and socioeconomic factors and access to health service and social programs. A < 0.05 significance level was adopted to select the interpreted canonical functions (CF) and ± 0.40 as canonical load value of the analyzed variables. RESULTS Three canonical functions were selected, concentrating 89.9% of the variability of the relationship among the groups. In the first canonical function, weight/age (-0.73) and height/age (-0.99) of the children were directly related to the mother’s height (-0.82), prenatal appointments (-0.43), geographical area of the residence (-0.41), and household income per capita (-0.42). Inverse relationship between the variables related to the children and people/room (0.44) showed that the larger the number of people/room, the poorer their nutritional status. Rural residents were found to have the worse nutritional conditions. In the second canonical function, the BMI of the mother (-0.48) was related to BMI/age and retinol of the children, indicating that as women gained weight so did their children. Underweight women tended to have children with vitamin A deficiency. In the third canonical function, hemoglobin (-0.72) and retinol serum levels (-0.40) of the children were directly related to the mother’s hemoglobin levels (-0.43). CONCLUSIONS Mothers and children were associated concerning anemia, vitamin A

    To address the need for longitudinal marital research that takes contextual factors into account, we investigated change in women's marital satisfaction over 18 years of middle age. We examined not only whether marital satisfaction changed, but also why and how it changed. Marital satisfaction increased in middle age, and increased marital, but not life, satisfaction was linked to the transition to an empty nest. More specifically, the transition to an empty nest increased marital satisfaction via an increase in women's enjoyment of time with their partners, but not via an increase in the quantity of that time with partners. Also, increasing marital satisfaction was not attributable to changing partners. Taken together, these findings support the utility of applying a contextualized approach focused on major life transitions to the study of long-term change in marital satisfaction.

    This study used the Movement Assessment Battery for Children (M-ABC2) to assess motor skills in children aged 7-10 years with autism (n = 18) in comparison to two groups of age-matched typically developing children; a receptive vocabulary matched group (n = 19) and a nonverbal IQ matched group (n = 22). The results supported previous work, as indicated by a significant general motor impairment in the group with autism. However, sub-analysis of the M-ABC2 revealed that there were only 2 out of 8 subcomponent skills which showed universal significant specific deficits for the autism group; i.e. catching a ball and static balance. These results suggest that motor skill deficits associated with autism may not be pervasive but more apparent in activities demanding complex, interceptive actions or core balance ability.

    Data from the New Horizons mission to Pluto show no craters on Sputnik Planum down to the detection limit (2 km for low resolution data, 625 m for high resolution data). The number of small Kuiper Belt Objects that should be impacting Pluto is known to some degree from various astronomical surveys. We combine these geological and telescopic observations to make an order of magnitude estimate that the surface age of Sputnik Planum must be less than 10 million years. This maximum surface age is surprisingly young and implies that this area of Pluto must be undergoing active resurfacing, presumably through some cryo-geophysical process. We discuss three possible resurfacing mechanisms and the implications of each one for Pluto's physical properties. PMID:26790001

    Data from the New Horizons mission to Pluto show no craters on Sputnik Planum down to the detection limit (2 km for low resolution data, 625 m for high resolution data). The number of small Kuiper Belt Objects that should be impacting Pluto is known to some degree from various astronomical surveys. We combine these geological and telescopic observations to make an order of magnitude estimate that the surface age of Sputnik Planum must be less than 10 million years. This maximum surface age is surprisingly young and implies that this area of Pluto must be undergoing active resurfacing, presumably through some cryo-geophysical process. We discuss three possible resurfacing mechanisms and the implications of each one for Pluto’s physical properties. PMID:26790001

    An anonymous prospective survey was carried out of children under 8 years of age prescribed a first pair of spectacles from the Royal Berkshire Hospital between August 1995 and May 1996, focusing on compliance in relation to refractive error, visual status and social factors. One hundred and thirty-three children were surveyed. Mean compliance was high (79.5/100) and spectacles were well liked by most children. Improvement in vision had little or no relationship with compliance. Significant factors were fit and what friends said about the spectacles. Adverse comments were rare, especially in the younger children, but increased with age. In pre-school children spectacles did not appear to be the salient feature in negative social judgements that has been found to occur in adults.

  2. Being overweight and obese: Black children ages 2-5 years.

    Obesity in children is a significant public health concern. The prevalence of obesity in Black preschoolers (ages 2-5 years) is slightly higher than in whites. However, by age 6, Black children experience higher obesity prevalence. The consequences to health throughout childhood and into adulthood have both medical and economic cost to individuals and society. Factors associated with obesity in preschool children are lifestyle behaviors such as diet, level of activity, culture, environment, and parental perceptions. Programs should target young Black children and their families to reduce the incidence of obesity and promoting healthy behaviors could aid in eliminating health disparities and improving quality of life. Nurses need to provide comprehensive culturally appropriate strategies at community and individual/family levels to prevent overweight and obesity in children.

    Background Generating percentile values is helpful for the identification of children with specific fitness characteristics (i.e., low or high fitness level) to set appropriate fitness goals (i.e., fitness/health promotion and/or long-term youth athlete development). Thus, the aim of this longitudinal study was to assess physical fitness development in healthy children aged 9–12 years and to compute sex- and age-specific percentile values. Methods Two-hundred and forty children (88 girls, 152 boys) participated in this study and were tested for their physical fitness. Physical fitness was assessed using the 50-m sprint test (i.e., speed), the 1-kg ball push test, the triple hop test (i.e., upper- and lower- extremity muscular power), the stand-and-reach test (i.e., flexibility), the star run test (i.e., agility), and the 9-min run test (i.e., endurance). Age- and sex-specific percentile values (i.e., P10 to P90) were generated using the Lambda, Mu, and Sigma method. Adjusted (for change in body weight, height, and baseline performance) age- and sex-differences as well as the interactions thereof were expressed by calculating effect sizes (Cohen’s d). Results Significant main effects of Age were detected for all physical fitness tests (d = 0.40–1.34), whereas significant main effects of Sex were found for upper-extremity muscular power (d = 0.55), flexibility (d = 0.81), agility (d = 0.44), and endurance (d = 0.32) only. Further, significant Sex by Age interactions were observed for upper-extremity muscular power (d = 0.36), flexibility (d = 0.61), and agility (d = 0.27) in favor of girls. Both, linear and curvilinear shaped curves were found for percentile values across the fitness tests. Accelerated (curvilinear) improvements were observed for upper-extremity muscular power (boys: 10–11 yrs; girls: 9–11 yrs), agility (boys: 9–10 yrs; girls: 9–11 yrs), and endurance (boys: 9–10 yrs; girls: 9–10 yrs).

    The objective of this study was to confirm whether gymnastics practice from a young age can induce greater vertical jump reliability. Fifty young female gymnasts (8.84 ± 0.62 years) and 42 females in the control group (8.58 ± 0.92 years) performed the following jump tests on a contact mat: squat jump, countermovement jump, countermovement jump with arm swing and drop jump from heights of 40 and 60 cm. The two testing sessions had three trials each and were separated by one week. A 2 (groups) × 2 (sessions) × 3 (trials) repeated measures analysis of variance (ANOVA) and a test-retest correlation analysis were used to study the reliability. There was no systematic source of error in either group for non-plyometric jumps such as squat jump, countermovement jump, and countermovement jump with arm swing. A significant group per trial interaction revealed a learning effect in gymnasts' drop jumps from 40 cm height. Additionally, the test-retest correlation analysis and the higher minimum detectable error suggest that the quick drop jump technique was not fully consolidated in either group. At an introductory level of gymnastics and between the ages of 8-10 years, the condition of being a gymnast did not lead to conclusively higher reliability, aside from better overall vertical jump performance.

    OBJECTIVE To analyze the factors associated with stiffness of the great arteries in prepubertal children. METHODS This study with convenience sample of 231 schoolchildren aged 9-10 years enrolled in public and private schools in Vitória, ES, Southeastern Brazil, in 2010-2011. Anthropometric and hemodynamic data, blood pressure, and pulse wave velocity in the carotid-femoral segment were obtained. Data on current and previous health conditions were obtained by questionnaire and notes on the child’s health card. Multiple linear regression was applied to identify the partial and total contribution of the factors in determining the pulse wave velocity values. RESULTS Among the students, 50.2% were female and 55.4% were 10 years old. Among those classified in the last tertile of pulse wave velocity, 60.0% were overweight, with higher mean blood pressure, waist circumference, and waist-to-height ratio. Birth weight was not associated with pulse wave velocity. After multiple linear regression analysis, body mass index (BMI) and diastolic blood pressure remained in the model. CONCLUSIONS BMI was the most important factor in determining arterial stiffness in children aged 9-10 years. PMID:25902563

    Anemia in children under 5 years of age, defined by the World Health Organization as a hemoglobin concentration < 11 g/dL, is a global public health problem. According to the 2006 Demographic Health Survey, the prevalence of anemia among children under five in Uganda was 72% in 2006. The 2009 Uganda Malaria Indicator Survey was conducted in late 2009 and revealed that over 60% of children less than 5 years of age were anemic and that over half of children tested positive for malaria via a rapid diagnostic test. Children with concomitant malaria infection, and in households without any type of mosquito net were more likely to be anemic, confirming that children under 5 years, are vulnerable to both the threat of malaria and anemia and the beneficial effect of malaria prevention tools. However, prevention and treatment of other factors associated with the etiology of anemia (e.g., iron deficiency) are likely necessary to combat the toll of anemia in Uganda.

    Background Intellectual disability (ID), characterized by impairments in intellectual function and adaptive behavior, affects 1-3% of the population. Many studies investigated its etiology, but few are cohort studies in middle-income countries. Aims To estimate prevalence, etiology, and factors related to ID among children prospectively followed since birth in a Southern Brazilian city (Pelotas). Methods In 2004, maternity hospitals were visited daily and births were identified. Live-born infants (n = 4,231) whose family lived in the urban area have been followed for several years. At the age of 2 and 4 years, performances in development and intelligence tests were evaluated using the Battelle Developmental Inventory and Wechsler Intelligence Scale, respectively. Children considered as having developmental delay were invited to attend a genetic evaluation. Results At 4 years of age, the prevalence of ID was 4.5%, and the etiology was classified into 5 groups: environmental (44.4%), genetic (20.5%), idiopathic (12.6%), neonatal sequelae (13.2%), other diseases (9.3%). Most children presented impairment in two or more areas of adaptive behavior. There was no difference in prenatal care attendance or maternal schooling among the groups. Conclusion For about 40% of children, ID was attributed to nonbiological factors, suggesting that the rate may be reduced with appropriate interventions early in life. PMID:27595410

    To what degree does being male or female influence the development of manual skills in pre-pubescent children? This question is important because of the emphasis placed on developing important new manual skills during this period of a child's education (e.g. writing, drawing, using computers). We investigated age and sex-differences in the ability of 422 children to control a handheld stylus. A task battery deployed using tablet PC technology presented interactive visual targets on a computer screen whilst simultaneously recording participant's objective kinematic responses, via their interactions with the on-screen stimuli using the handheld stylus. The battery required children use the stylus to: (i) make a series of aiming movements, (ii) trace a series of abstract shapes and (iii) track a moving object. The tasks were not familiar to the children, allowing measurement of a general ability that might be meaningfully labelled ‘manual control’, whilst minimising culturally determined differences in experience (as much as possible). A reliable interaction between sex and age was found on the aiming task, with girls' movement times being faster than boys in younger age groups (e.g. 4–5 years) but with this pattern reversing in older children (10–11 years). The improved performance in older boys on the aiming task is consistent with prior evidence of a male advantage for gross-motor aiming tasks, which begins to emerge during adolescence. A small but reliable sex difference was found in tracing skill, with girls showing a slightly higher level of performance than boys irrespective of age. There were no reliable sex differences between boys and girls on the tracking task. Overall, the findings suggest that prepubescent girls are more likely to have superior manual control abilities for performing novel tasks. However, these small population differences do not suggest that the sexes require different educational support whilst developing their manual skills

    Out of 1 billion couples there are only 124 million who use modern and effective contraceptives. World abortions number 33 million/year. 250 million sexually active women of child-bearing age in developing countries outside China do not use modern and effective contraceptives. Fertility control costs on the average US$2.5 billion a year in each developing country, 20% of which is assistance from developed countries. Expanding the family planning service to the 250 million sexually active child-bearing aged women costs an additional U.S. $5 billion yearly. A family planning accessibility survey was conducted by the Population Crisis Committee. PCC divided the countries into 2 categories: Developed and developing countries. The 110 countries (15 developed and 95 developing) covered 96% of the world population. The survey placed the countries in 5 classes according to accessibility levels: Excellent, good, fair, poor, very poor. The developed countries were analyzed according to effective contraceptive methods, service to the poor and minorities, sex education in the schools, and family planning information and advertisement. The developing countries were analyzed according to effective contraceptive methods, performance of service and distribution, public information and education, private sector participation, government finance and policies. Of the 15 developed countries, 43% were excellent, 22% good, 24% fair, and 2% poor. Of the 95 developing countries, 5 were excellent, 10 good, 16 fair, and 64 either poor or very poor countries in respect to family planning accessibility. In the face of a population explosion in the year 2000, many countries lack of government support for family planning programs. After 30 years of world effort in population control, half of the world population still has no effective family planning services.

    Purpose To examine outcomes of mammography screening among women ≥ 80 years to inform decision making. Patients and Methods We conducted a cohort study of 2,011 women without a history of breast cancer who were age ≥ 80 years between 1994 and 2004 and who received care at one academic primary care clinic or two community health centers in Boston, MA. Medical record data were abstracted on all screening and diagnostic mammograms, breast ultrasounds and biopsies performed, all breast cancers diagnosed through December 31, 2006, and on sociodemographics. Date and cause of death were confirmed using the National Death Index. Results The majority of patients (78.6%) were non-Hispanic white and 51.4% (n = 1,034) had been screened with mammography since age 80 years. Among women who were screened, eight were diagnosed with ductal carcinoma in situ, 16 with early stage disease (1.5%), two with late stage disease, and one died as a result of breast cancer. Many (110; 11%) experienced a false-positive screening mammogram that led to 19 benign breast biopsies, eight refused work-up, and three experienced a false-negative screening mammogram; 97 were screened within 2 years of their death from other causes. There were no significant differences in the rate, stage, recurrence rate, or deaths due to breast cancer between women who were screened and those who were not screened. Conclusion The majority of women ≥ 80 years are screened with mammography yet few benefit. Meanwhile, 12.5% experience a burden from screening. The data from this study can be used to inform elderly women's decision making and potentially lead to more rational use of screening. PMID:19255318

    The ((pi)('+),(pi)('-)) double-charge-exchange (DCX) reaction has been performed on targets of T = 0,1 isospin (and isotopic) pairs ('16,18)O and ('24,26)Mg. Energy excitation functions of d(sigma)/d(OMEGA), across the (3,3) (pi)-N resonance, are presented for transitions to double -isobaric analog state (DIAS) and non-DIAS ground-state residual nuclei. Angular distributions in the region of 5(DEGREES)-33(DEGREES) are presented for the DIAS from the T = 1 nuclei. The simularities and differences of DIAS and non-DIAS distributions are discussed in relation to reaction-mechanism and nuclear-structure effects. Also, a simple, two-amplitude model for the ('18)O excitation function, consistent with the data, is presented. The utility of DCX in nuclear mass measurements is discussed, with some examples.

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

    To evaluate the role of postnatal growth on IQ at 3 years of age, 139 appropriate for gestational age, very low birth weight infants (less than 1.5 kg) born in 1977 and 1978 were studied at 40 weeks (term), and at 8, 20, and 33 months (corrected) of age. Weight, height, and head circumference were measured at each age, neurologic status was measured at 20 months, and Stanford Binet IQ at 33 months. Multiple regression analysis revealed that head circumference at 8 months of age is the best growth predictor of IQ at 3 years of age. Path analysis was performed to measure the effects of biologic and social factors measured earlier in life on IQ at 3 years. These factors explained 43% of the variance in IQ at 3 years of age. Head circumference at 8 months had a direct effect on IQ at 3 years, controlling for all other variables in the model. Neonatal risk had an indirect effect via head circumference. Neurologic impairment had direct and indirect (via head circumference) effects; race and socioeconomic status had direct effects on IQ but no effects on growth at 8 months of age. Thus, brain growth at 8 months significantly influenced 3 year IQ at 3 years of age among very low birth weight infants, even when medical and sociodemographic variables were controlled.

    The age threshold of 14 years is relevant in Italy as the minimum age for criminal responsibility. It is of utmost importance to evaluate the diagnostic accuracy of every odontological method for age evaluation considering the sensitivity, or the ability to estimate the true positive cases, and the specificity, or the ability to estimate the true negative cases. The research aims to compare the specificity and sensitivity of four commonly adopted methods of dental age estimation - Demirjian, Haavikko, Willems and Cameriere - in a sample of Italian children aged between 11 and 16 years, with an age threshold of 14 years, using receiver operating characteristic curves and the area under the curve (AUC). In addition, new decision criteria are developed to increase the accuracy of the methods. Among the four odontological methods for age estimation adopted in the research, the Cameriere method showed the highest AUC in both female and male cohorts. The Cameriere method shows a high degree of accuracy at the age threshold of 14 years. To adopt the Cameriere method to estimate the 14-year age threshold more accurately, however, it is suggested - according to the Youden index - that the decision criterion be set at the lower value of 12.928 for females and 13.258 years for males, obtaining a sensitivity of 85% and specificity of 88% in females, and a sensitivity of 77% and specificity of 92% in males. If a specificity level >90% is needed, the cut-off point should be set at 12.959 years (82% sensitivity) for females.

    INTRODUCTION Acute pulmonary embolism (APE) is an urgent clinical condition that can progress in a wide variety of ways. Therefore, we sought to develop an easy-to-apply algorithm, to be based on readily available clinical indicators, effective in predicting unfavourable outcomes. METHODS This was a retrospective cohort study based on systematically collected data in a database. The study included 102 patients with APE who were admitted to a tertiary care hospital. The following outcomes were defined as unfavourable shock, the need for mechanical ventilation, the use of thrombolytics, and death. Logistic regression analysis was used to explore variables significantly associated with outcome and to calculate post-test probabilities. RESULTS The prevalence of unfavourable outcomes was 25.5% (26 of the 102 patients with APE). The risk of an unfavourable outcome was reduced to 7.0% for patients with APE who were aged ≤ 40 years. In patients with APE who were aged > 40 years, the presence of hypoxaemia (i.e. peripheral oxygen saturation < 90%) alone increased the risk of an unfavourable outcome to 57.0%. A recent history of trauma and the presence of pre-existing lung or heart disease were significantly associated with unfavourable outcomes. The inclusion of those variables in the logistic regression model increased the post-test risk of an unfavourable outcome to 65.0%–86.0%. CONCLUSION Advanced age (i.e. > 40 years), the presence of hypoxaemia, a recent history of trauma and the presence of pre-existing lung or heart disease are risk factors for unfavourable outcome in patients with APE.

    Sex is one of major factors of individual variability. In kinesiology, we explore and record changes brought on by growth and development, so we will use a sample of 1020 subjects, at the age of powerful changes caused by sexual maturation, to investigate differences in morphological characteristics of children and to determine the significance of differences based on sex. The aim of this transversal research was to determine the sex differentiation of morphological characteristics in 5th and 8th grade students of elementary school as well as structural differences between the sexes. Differential sex differences in the structure of morphological parameters surely exist, and in their basis lies in a different temporal, or periodical onset of development phases, while multivariate analysis of variance for each age removes any doubt about these differences being more than obvious. Differences in the structure of discriminant function in children aged 11 are conditioned primarily by diverse structuring of transverse dimensions, in a way that boys are distinctly superior in knee diameter, and girls in bicristal diameter. As early as the age of 11, it can clearly be recognized that pre-puberty had already progressed in girls, which is then followed by puberty. At the age of 12 girls are already experiencing a puberty spurt, which is manifested in further development of bicristal diameter and longitudinal dimensionality of the skeleton, particularly of lower extremities. Thirteen year old boys are on the verge of a puberty spurt, which is manifested through the development of longitudinal dimensionality, and to a lesser extent, of transverse dimensionality of the skeleton. Secondary discriminant distinctiveness can be observed continuously across all variables assessing the dimension of deposition of fat reserves, and also, absolute values of measures of subcutaneous fat tissue are more prominent in female students. It is indicative that subcutaneous fat deposits are

    Pulmonary function test of various types are utilized clinically and epidemiologically to measures the functional status of the lung and to asses the diseases. Spirometric standard for healthy Bangladeshi adults aged 18-40 years is conducted in National Institute of Diseases of Chest and Hospital (NIDCH). This is cross sectional study is establish normal value of lung functions for Bangladeshi adult. Total of 995 (628 males & 367 females) healthy adults were selected to obtain lung function values; from a healthy adult those who attended in the hospital as a patients attended and healthy stuff of NIDCH. A computerized spirometer was used to measure lung volume and flows in a standard way. The best of the three reading was taken as the correct value. Anthropometric parameters including age, weight and height were recorded appropriately and body mass index was calculated. The statistical package for the social science (SPSS-10.01) was used for the statistical analysis of the data. The pulmonary function data was separated by sex and classified on the basis of height weight age and body surface area. The mean and standard deviation was calculated for every such variable. The lung function variable shows a linear positive correlation with height, weight and age. Force vital capacity (FVC) and forced expiratory volume in 1st second (FEV1) increase in height. Males show higher values for lung function variables than female. Stepwise regression analysis was done using age, height and weight, BMI as independent variable strong correlation was found between lung function values and independent variables. Height shows the highest correlation. The regression equation for lung function variables was determined for males and females considering height as independent variable. Lung function values of Bangladeshi adult were significantly lower than Nigerian, British and American result but nearly similar to Indian result. Nomogram was constructed in relation to height for males

  19. Comparison of prevalence, viral load, physical status and expression of human papillomavirus-16, -18 and -58 in esophageal and cervical cancer: a case-control study

    PubMed Central

    2010-01-01

    Background Human papillomavirus (HPV) infection is a major risk factor for the development of nearly all cases of cervical cancer worldwide. The presence of HPV DNA in cases of esophageal squamous-cell carcinoma (ESCC) has been reported repeatedly from Shantou, China, and other regions with a high incidence of esophageal carcinoma (EC). However, unlike in cervical squamous-cell carcinoma (CSCC), in ESCC, the characteristics of HPV are unclear. Thus, the role of high-risk HPV types in the carcinogenesis of ESCC remains uncertain. Methods Seventy cases of ESCC with 60 controls and 39 cases of CSCC with 54 controls collected from patients in Shantou region in China were compared for the distributions of HPV-16, -18 and -58; viral load; and viral integration using real-time PCR assay and HPV-16 expression using immunostaining. Results The detection rates and viral loads of HR-HPV infection were significantly lower in ESCC than in CSCC (50.0% vs. 79.48%, P = 0.005; 2.55 ± 3.19 vs. 361.29 ± 441.75, P = 0.002, respectively). The combined integration level of HPV-16, -18 and -58 was slightly lower in ESCC than in CSCC (P = 0.022). HPV-16 expression was detected in 59.26% of ESCC tissue and significantly associated with tumour grade (P = 0.027). Conclusions High levels of HR-HPV expression and integration may be an indicator of the risk of ESCC, at least for patients in the Shantou region of China. However, a relatively low HPV copy number and infection rate in ESCC is unlikely to play an essential a role in the carcinogenesis of ESCC as in cervical cancer. Factors other than HR-HPV infection may contribute to the carcinogenesis of ESCC. PMID:21108842

    A study has been made of the changes in refraction as a sample of 148 children grew between the ages of 1 and 3 1/2 years. There was no decrease in hypermetropia, but there was a significant decrease in the incidence of astigmatism. Study of the changes in the refraction in the horizontal and vertical meridia of individual eyes gave clear evidence of a trend towards emmetropia if the initial refraction in either meridian was myopic or less than +2.50 D. Above that level the refraction became more or less hypermetropic. PMID:465408

  1. Mathematical Model for the 0.5 Billion Years Aged Sun

    Tatomir, E.

    An algorithm is given for constructing evolutionary tracks for a star with the mass equal to one solar mass. The presented model can be applied to the stars belonging to the inferior main sequence, which have the proton-proton reaction as energy source and present a radiative core and a convective shell. This paper presents an original way of solving the system of equations corresponding to the radiative nucleus by using Taylor's series in close vicinity to the center of the Sun. It also presents the numerical integration and the results for a 0.5 billion years aged solar model.

    The older adult population is growing rapidly in the USA and it is expected that by 2040 the number of adults ≥ 65 years of age will have increased by about 50%. With the growth of this subpopulation, oral health status, and periodontal status in particular, becomes important in the quest to maintain an adequate quality of life. Poor oral health can have a major impact, leading to tooth loss, pain and discomfort, and may prevent older adults from chewing food properly, often leading to poor nutrition. Periodontitis is monitored in the USA at the national level as part of the Healthy People 2020 initiative. In this report, we provide estimates of the overall burden of periodontitis among adults ≥ 65 years of age and after stratification according to sociodemographic factors, modifiable risk factors (such as smoking status), the presence of other systemic conditions (such as diabetes) and access to dental care. We also estimated the burden of periodontitis within this age group at the state and local levels. Data from the National Health and Nutrition Examination Survey 2009/2010 and 2011/2012 cycles were analyzed. Periodontal measures from both survey cycles were based on a full-mouth periodontal examination. Nineteen per cent of adults in this subpopulation were edentulous. The mean age was 73 years, 7% were current smokers, 8% lived below the 100% Federal Poverty Level and < 40% had seen a dentist in the past year. Almost two-thirds (62.3%) had one or more sites with ≥ 5 mm of clinical attachment loss and almost half had at least one site with probing pocket depth of ≥ 4 mm. We estimated the lowest prevalence of periodontitis in Utah (62.3%) and New Hampshire (62.6%) and the highest in New Mexico, Hawaii, and the District of Columbia each with a prevalence of higher than 70%. Overall, periodontitis is highly prevalent in this subpopulation, with two-thirds of dentate older adults affected at any geographic level. These findings provide an

    Comparable samples of low-risk adopted and nonadopted children and mothers were observed during 3 tasks at age 4 years. Quality of mother-child interactions, child level of functioning in 4 domains, and maternal parenting satisfaction and social support were assessed. Adopted children were as competent as nonadopted children on measures of developmental functioning. Both groups of mothers expressed high satisfaction and support as parents. However, ratings of child, maternal, and dyadic behavior when interacting were all lower for adoptive dyads than for nonadoptive dyads, and adoptive dyads with boys accounted for the maternal and dyadic group differences.

    Objective To investigate whether short sleep duration from the first year of life influenced weight at an early age. Study design During 2004, children born in Pelotas, Brazil, were enrolled in a cohort study. Sleeping habits during the previous 2 weeks were assessed, and the children were weighed and measured at 1-, 2-, and 4-year follow-ups. Overweight and obesity at 4 years were defined according to World Health Organization z-scores for body mass index for age. Short sleep duration was defined as fewer than 10 hours of sleep per night at any follow-up. Results Out of the 4263 live births, 4231 were recruited. The prevalence of short sleep duration at any follow-up from 1-4 years of age was 10.1%. At 4 years of age, 201 children were obese (5.3%), and 302 (8%) were overweight. Among short sleepers, the prevalence ratio for overweight/obesity after adjusting for maternal and children's characteristics was 1.32 (1.03; 1.70). Conclusions Children who slept for fewer than 10 hours per night at any follow-up from 1-4 years of age were more likely to be overweight or obese at 4 years of age, despite their sociodemographic and sleep characteristics.

    This study leveraged data from the Minnesota Longitudinal Study of Risk and Adaptation (N = 243) to investigate the predictive significance of maternal sensitivity during the first three years of life for social and academic competence through age 32 years. Structural model comparisons replicated previous findings that early maternal sensitivity predicts social skills and academic achievement through mid-adolescence in a manner consistent with an Enduring Effects model of development and extended these findings using heterotypic indicators of social (effectiveness of romantic engagement) and academic competence (educational attainment) during adulthood. Although early socioeconomic factors and child gender accounted for the predictive significance of maternal sensitivity for social competence, covariates did not fully account for associations between early sensitivity and academic outcomes PMID:25521785

    Background and purpose Femoral deformity associated with osteoarthritis is a challenge for both the surgeon and the implant. Many of the patients with these deformities are young. Standard implants can be difficult to fit into these femurs. We prospectively evaluated the outcome of custom uncemented femoral stems in young patients. Methods 61 consecutive patients (72 hips) underwent surgery for osteoarthritis because of femoral deformity at a mean age of 35 (22–40) years. The patients received a CT3D-A custom-made femoral stem and an uncemented cup. The mean follow-up time was 14 (10–16) years. 2 patients died at 7 and 8 years after surgery, otherwise, none of the patients were lost to follow-up. Results At follow-up, the femoral prosthesis had not been revised in 59 patients (70 hips). 3 patients (3 hips) had required revision surgery due to loosening of the acetabular component; 2 hips were awaiting revision surgery for loosening of the acetabular cup. There were no cases of dislocation or infection. At review, all stems were considered stable according to the radiographic criteria. No migration or subsidence was observed on plain radiographs. Interpretation Our results are comparable to published results of custom stems regarding survival and outcome. Considering the young age and the deformities in this series of uncemented custom femoral stems, and the fact that there was follow-up of up to 16 years, the survival is remarkable. This technique appears to be a reasonable alternative in younger patients with femoral deformities. PMID:19513891

    Objective While osteoarthritis (OA) has mainly been viewed as a disease affecting older people, its prevalence in younger adults is substantial. However, there is limited research on how younger adults understand knee symptoms. This article explores the meaning of knee symptoms to adults ages 35–65 years. Methods This qualitative study comprised 6 focus groups and 10 one‐on‐one interviews with 51 participants (median age 49, 61% female), who self‐reported knee OA or reported knee symptoms (i.e., pain, aching, or stiffness) on most days of the past month. Constructivist grounded theory guided the sampling, data collection, and analysis. Data were analyzed using a constant comparative method. Results Central to participants’ understanding of knee symptoms was the perception that symptoms were preventable, meaning that there was the potential to prevent the onset of symptoms and to alter the course of symptoms. This understanding was demonstrated in participants’ explanation of symptoms. Participants commented on the cause, prevention, and course of symptoms. Moreover, participants reflected on their experience with symptoms, indicating that symptoms made them feel older than their current age. However, they did not perceive their symptoms as normal or acceptable. Conclusion Participants interpreted knee symptoms as potentially preventable, suggesting that they may be open to primary and secondary prevention strategies. PMID:26238409

  11. Functional development of the CNS in pupils aged 7 to 19 years.

    In pupils aged 7 to 19 years, the functioning of the central nervous system (CNS) improved by a factor of 3 during their development. The CNS functioning was quantified in the framework of the dynamical system theory of pattern formation by the value of coordination dynamics. A transient increase in the optimal rate of arm and leg movements was observed in the pupils within 8 and 14 years of age. This high-speed moving is interpreted as a mean how the immature CNS tries to improve its functioning with respect to coordination and symmetry. Moreover, in very young pupils a lack of continuous drive of the CNS was observed; in other words, the concentration upon a certain task was not continuous. Some pupils were able to concentrate for only approximately 10 s. It was difficult for young pupils to simultaneously concentrate on two different tasks like moving and speaking or moving and thinking. It is concluded that concentration problems observed in young pupils are due to their immature CNS. PMID:16918200

    We performed a retrospective cohort study between 2002 and 2014 to compare liver transplantation outcomes between recipients of grafts from donors older than and younger than the age of 80 years. Numerical variables were compared with the Student t test when their distribution was normal and the Mann-Whitney test when it was not, whereas categorical variables were compared with Pearson chi-squared test or Fisher test, as appropriate; P < .05 was considered significant. The study included 312 patients with organs from donors younger than 80 years of age and 17 with organs from older donors. The 2 recipient groups did not significantly differ in weight, height, gender, body mass index (BMI), CHILD or MELD score, intensive care unit (ICU) or hospital stay, need for intraoperative hemoderivatives, postreperfusion syndrome, biliary or vascular complications, ischemic cholangiopathy, number of repeat surgeries, graft rejection, retransplantation, or survival at 6 months. Although earlier studies considered livers from elderly donors to be suboptimal, our results support the proposition that octogenarian donors can be an excellent source of liver grafts.

    Oxygen isotope records from Chinese caves characterize changes in both the Asian monsoon and global climate. Here, using our new speleothem data, we extend the Chinese record to cover the full uranium/thorium dating range, that is, the past 640,000 years. The record's length and temporal precision allow us to test the idea that insolation changes caused by the Earth's precession drove the terminations of each of the last seven ice ages as well as the millennia-long intervals of reduced monsoon rainfall associated with each of the terminations. On the basis of our record's timing, the terminations are separated by four or five precession cycles, supporting the idea that the '100,000-year' ice age cycle is an average of discrete numbers of precession cycles. Furthermore, the suborbital component of monsoon rainfall variability exhibits power in both the precession and obliquity bands, and is nearly in anti-phase with summer boreal insolation. These observations indicate that insolation, in part, sets the pace of the occurrence of millennial-scale events, including those associated with terminations and 'unfinished terminations'.

    Present cartography procedures for quantitative indicators are arbitrary on choice of the number of categories in which a particular area is to be divided. The choice of initial cutoff and the choice of the width of each category is also arbitrary. To remove this arbitrariness and thus to introduce objectivity, we propose use of a statistical procedure called cluster analysis. This procedure is easy to use on a computer. We also propose using computer based maps. We use these methods on mortality indicators upto age of one year for major states of India to devise objective maps. The terminology of mortality indicators upto age of one year has been used by UNICEF document(1). The mortality indicators analysed are infant mortality rate, neonatal mortality rate, postneonatal mortality rate, perinatal mortality rate and still birth rate. Different indicators reveal different pictures. In this paper, we also propose an innovation to obtain an integrated picture by simultaneously considering all the four indicators in a multivariate setting. Such mapping could help the health managers and planners to devise more effective strategies to control child mortality.

  16. In Search of Emerging Same-Sex Sexuality: Romantic Attractions at Age 13 Years.

    Sex-typed behavior in childhood is significantly related to sexual orientation in adulthood. In addition, same-sex attractions in early adolescence are more non-exclusive than in adulthood and can differ from later same-sex orientations. However, little research has focused on romantic attractions as they emerge during early adolescence. Drawing a sample from the Avon Longitudinal Study of Parents and Children (197 girls, 204 boys), the current study examined whether same-sex romantic attractions at age 13 years were exclusive, and whether they were predicted by sex-typed behavior at age 3.5 years. No young adolescents in this sample reported exclusive same-sex attractions, and increased same-sex attractions were not significantly related to reduced other-sex sexualities. Childhood sex-typed behavior did not significantly predict early same-sex attractions, suggesting that early same-sex attractions differ from later same-sex orientations. The current study highlights the importance of studying the development of sexuality beginning prior to adulthood.

    Objective: Nutrition in childhood has an important role in current and adulthood health. Recent studies have shown that the mother’s lifestyle has an important role in the methods used by mother to feed child. This paper aimed to investigate the association between mother’s weight efficacy lifestyle with feeding practices in children aged 3- 6 years. Materials and Methods: In this cross-sectional study which was carried out in 30 primary schools of Rasht (Iran) in 2012, 165 mothers with children aged 3-6 years were participated. Mothers reported their own and their child’s demographics. Aspects of mother’s weight efficacy lifestyle and mother’s control practices were assessed using Weight Efficacy Lifestyle (WEL) questionnaire and Comprehensive Feeding Practices questionnaire (CFPQ) respectively. Height and weight of mothers participated in the study were measured. The role of mother’s weight efficacy in predicting child’s feeding practices was assessed using linear regression. Results: Results showed that mother’s weight efficacy was related to child feeding practices. The mothers with similar weight efficacy lifestyle applied similar methods in child nutrition. Mothers with better weight efficacy used more encourage balance and variety, environmental control, child involvement and less emotion regulation using foods. Conclusion: ‎ ‏ ‏‎ The result of the ‎study showed that maternal ‎lifestyle was associated with ‎child feeding practices.‎ PMID:27006673

    Background: Patients suffering from atopic dermatitis often describe food hypersensitivity. Rising prevalence of food hypersensitivity and severe allergic reactions to foods have been reported, but the data are scarce. Aims and Objectives: Evaluation of food hypersensitivity reactions in patients suffering from atopic dermatitis. Materials and Methods: The dermatological examination was performed in patients of age 14 years and above and the detailed history was taken concerning the food hypersensitivity. Results: A total of 228 patients were examined-72 men, 156 women, average age 26.2 (SD 9.5) years. The food hypersensitivity reactions were recorded in 196 patients from 228 (86%), no reactions were recorded in 32 patients (24%). Foods with the most often recorded reactions are: Nuts (in 35% of patients), tomatoes (in 20%), and kiwi (in 17, 5%), apples and spices (in 16%), tangerines and oranges (in 15%), capsicum (in 13%), fishes (in 12%), celery (in 9%), and chocolate (in 7%). Conclusion: Food hypersensitivity reactions are recorded in 86% of patients suffering from atopic dermatitis. Nuts, tomatoes, and pollen–associated foods play a role in the majority of patients suffering from atopic dermatitis. PMID:24891679

    The HIV-infected population is ageing. Issues including polypharmacy and co-morbidities led us to develop a dedicated clinic for HIV-infected individuals over 50. We describe our service evaluation after two years. The over 50 clinic commenced in January 2009. The team comprises a registrar, consultant, nurse practitioner and is supported by a pharmacist and mental health services. Patients undergo a full medication and drug interactions review, neurocognitive assessment, adherence self-assessment and investigations including therapeutic drug monitoring (TDM), coronary artery calcium scores (CACS) and bone mineral density. Over two years of activity, 150 patients attended the service. Median (range) age was 58 (50-88), all were on combined antiretroviral therapy and 38% (57/150) were on ≥3 non-HIV drugs. CACS was high (>90th centile) in 14%. Thirty-eight percent had osteopaenia and 18% had osteoporosis requiring treatment. Thirteen out of 125 men had an increased prostate specific antigen, four were diagnosed with prostate cancer. Drug interaction, TDM and neurocognitive assessments were useful for several patients. Asymptomatic patients over 50 in long-term follow-up had new pathologies detected through targeted screening. The clinic has improved general practitioner (GP) liaison and facilitated closer working relationships with other specialties. Patients have reacted positively to the clinic, particularly as many do not routinely access their GP. PMID:22930290

    Objectives. Persons with fibromyalgia (FM) report having cognitive dysfunction. Neuropsychological performance was compared across a variety of domains in 43 women with FM (M age = 63 years) and in 44 women without FM (M age = 65 years). Method. Measures included explicit memory (Consortium to Establish a Registry for Alzheimer’s Disease [CERAD] immediate/delayed recall, delayed recognition), aspects of executive function including interference/inhibition (Stroop Color/Word test), working memory (Digit Span Forward/Backward), set-shifting/complex sequencing (Trails B), monitoring (verbal fluency: naming animals), processing speed (Trails A, Digit Symbol Substitution Coding), and problem solving (Everyday Problems Test). Results. Women with FM performed more poorly than controls on executive function (Stroop Color/Word) and one processing speed measure (Digit Symbol Substitution Coding). Discussion. Results partly support altered cognitive function in FM. Mixed findings across cognitive domains among individuals with or without FM is consistent with the literature and suggest that factors beyond those typically controlled for (e.g., heterogeneity in FM) may be influencing findings. Future research is warranted. PMID:23275498

    Normative measures of open quotient, speed quotient, maximum flow declination rate (MFDR), and subglottal pressure were determined for 75 children between the ages of 6 years 0 months and 10 years 11 months. The participants produced a sustained /a/ at low, comfort, and high pitches for a minimum of 5 seconds, and five to seven repetitions of /pa/ at low, comfort, and high pitches. No statistically significant differences were found in the mean measures of any aerodynamic variables (open quotient, speed quotient, maximum flow declination rate, subglottal pressure) between the frequency levels (low, comfort, high pitches). Also, no strong evidence (P > .05) exists that age or sex effect differed between the frequency levels (low, comfort, high) for any of the aerodynamic measures. For /a/ response tasks, mean open quotient measures increased slightly from low to comfort frequency and from comfort to high frequency. Mean speed quotient measures showed minimal differences between low and comfort frequency, with decreased mean measures for high frequency. Mean MFDR measures increased from low to comfort frequency and from comfort to high frequency. Mean subglottal pressure measures increased slightly from low to comfort frequency and from comfort to high frequency.

    Early accumulation of n-3 long-chain PUFA (LCPUFA) in the brain may contribute to differences in later cognitive abilities. In this study, our objective was to examine whether fish oil (FO) supplementation during lactation affects processing speed, working memory, inhibitory control, and socioemotional development at 7 years. Danish mothers (n = 122) were randomized to FO [1.5 g/d n-3 LCPUFA] or olive oil (OO) supplementation during the first 4 months of lactation. The trial also included a high-fish intake (HFI) reference group (n = 53). Ninety-eight children were followed-up with an assessment of processing speed, an age-appropriate Stroop task, and the Strength and Difficulties Questionnaire at 7 year. A group effect of the intervention (FO vs. OO) was found in prosocial behavior scores; this negative effect was carried by the boys. Exploratory analyses including all participants revealed the speed of processing scores were predicted by maternal n-3 LCPUFA intake during the intervention period (negative relation) and maternal education (positive relation). Stroop scores indicative of working memory and inhibitory control were predicted by infant erythrocyte DHA status at 4 months of age (negative relation). Early fish oil supplementation may have a negative effect on later cognitive abilities. Speed of processing and inhibitory control/working memory are differentially affected, with speed of processing showing effects of fish oil intake as a whole, whereas inhibitory control/working memory was related more specifically to DHA status.

    A linked data file of birth records and hospital admissions was used to investigate inpatient hospital morbidity before 2 years of age for all non-Aboriginal and Aboriginal children born in Western Australia in 1986. Of the non-Aboriginal children, 31.8% were admitted to hospital at least once before the age of 2 years, with an overall admission rate of 526/1000 live births; the corresponding figures for Aboriginal children were 68.7% and 2797. The mean number of days in hospital for each non-Aboriginal child admitted was 7.4, and 26.5 for Aboriginal children. Of the total cohort, 21% of non-Aboriginal and 20% of Aboriginal children were admitted only once, and 4% of non-Aboriginal and 36% of Aboriginal children were admitted at least three times; 23% of non-Aboriginal and 24% of Aboriginal children were admitted for only one major disease category, and 1% of non-Aboriginal and 16% of Aboriginal children were in at least four categories. The highest admission rates and highest percentages of the cohort admitted were for gastrointestinal and respiratory diseases and social admissions. These results illustrate the importance for both descriptive and analytical research of relating admissions to hospital for the total population to the individual child, and of using clinically relevant disease classifications.

We used weighted data from the 2006–2010 National Survey of Family Growth to estimate the percentage of men aged 15 to 44 years (n = 10 395) in need of family planning, based on sexual behavior, fecundity, and not trying to get pregnant with his partner. Results. Overall, 60% of men were in need of family planning, defined as those who ever had vaginal sex, were fecund, and had fecund partner(s) who were not trying to get pregnant with partner or partner(s) were not currently pregnant. The greatest need was among young and unmarried men. Most men in need of family planning had access to care, but few reported receiving family planning services (< 19%), consistently using condoms (26%), or having partners consistently using contraception (41%). Conclusions. The need for engaging men aged 15 to 44 years in family planning education and care is substantial and largely unmet despite national public health priorities to include men in reducing unintended pregnancies.

    Fetal body composition is an important determinant of body composition at birth, and it is likely to be an important determinant at later stages in life. The purpose of this work is to provide a comprehensive overview by presenting data from previously published studies that report on body composition during fetal development in newborns and the infant/child through 5 years of age. Understanding the changes in body composition that occur both in utero and during infancy and childhood, and how they may be related, may help inform evidence-based practice during pregnancy and childhood. We describe body composition measurement techniques from the in utero period to 5 years of age, and identify gaps in knowledge to direct future research efforts. Available literature on chemical and cadaver analyses of fetal studies during gestation is presented to show the timing and accretion rates of adipose and lean tissues. Quantitative and qualitative aspects of fetal lean and fat mass accretion could be especially useful in the clinical setting for diagnostic purposes. The practicality of different pediatric body composition measurement methods in the clinical setting is discussed by presenting the assumptions and limitations associated with each method that may assist the clinician in characterizing the health and nutritional status of the fetus, infant and child. It is our hope that this review will help guide future research efforts directed at increasing the understanding of how body composition in early development may be associated with chronic diseases in later life.

    OBJECTIVE This study evaluated the relationship between prenatal exposure to airborne polycyclic aromatic hydrocarbons (PAHs) and child intelligence. METHODS Children of nonsmoking black or Dominican-American women residing in New York City were monitored from in utero to 5 years of age, with determination of prenatal PAH exposure through personal air monitoring for the mothers during pregnancy. At 5 years of age, intelligence was assessed for 249 children by using the Wechsler Preschool and Primary Scale of Intelligence-Revised. Multivariate linear regression models were used to estimate and to test the associations between prenatal PAH exposure and IQ. RESULTS After adjustment for maternal intelligence, quality of the home caretaking environment, environmental tobacco smoke exposure, and other potentially confounding factors, high PAH levels (above the median of 2.26 ng/m3) were inversely associated with full-scale IQ (P = .007) and verbal IQ (P = .003) scores. Children in the high-exposure group had full-scale and verbal IQ scores that were 4.31 and 4.67 points lower, respectively, than those of less-exposed children (≤2.26 ng/m3). The associations between logarithmically transformed, continuous, PAH levels and these IQ measures also were significant (full-scale IQ: β = −3.00; P = .009; verbal IQ: β = −3.53; P = .002). CONCLUSION These results provide evidence that environmental PAHs at levels encountered in New York City air can affect children’s IQ adversely. PMID:19620194

    The purpose was to evaluate the association between calcium (Ca) intake and adiposity in adolescents. A cross-sectional study of 125 adolescents 12 to 16 years. Ca intake was evaluated by 24-hour recall dietary surveys and food frequency consumption. Adiposity was measured by anthropometric methods and bioelectrical impedance (BIA). The association between Ca intake and adiposity was identified by simple correlation and multivariate models adjusted to energy consumption, age, sex and menarche. Mean age of adolescents was 13.5 +/- 0.8 years. A negative correlation was identified between Ca intake and anthropometric indicators weight, skinfolds, body mass index, fat mass and percentage of fat (the latter two by BIA and only in women). Multivariate analysis, including energy consumption showed no association between Ca intake and adiposity. In conclusion, Ca consumption does not associate with adiposity in adolescents; multivariate models showed that energy intake and menarche are the variables that show a higher association with adiposity at this stage of life.

    The Animal Fun program was designed to enhance the motor ability of young children by imitating the movements of animals in a fun, inclusive setting. The efficacy of this program was investigated through a randomized controlled trial using a multivariate nested cohort design. Pre-intervention scores were recorded for 511 children aged 4.83 years to 6.17 years (M=5.42 years, SD=3.58 months). Six control and six intervention schools were compared 6 months later following the intervention, and then again at 18 months after the initial testing when the children were in their first school year. Changes in motor performance were examined using the Bruininks-Oseretsky Test of Motor Proficiency short form. Data were analyzed using multi-level-mixed effects linear regression. A significant Condition×Time interaction was found, F(2,1219)=3.35, p=.035, demonstrating that only the intervention group showed an improvement in motor ability. A significant Sex×Time interaction was also found, F(2,1219)=3.84, p=.022, with boys improving over time, but not girls. These findings have important implications for the efficacy of early intervention of motor skills and understanding the differences in motor performance between boys and girls. PMID:23186610

    Background Childhood trauma exposure has been associated with deficits in cognitive functioning. The influence of timing of exposure on the magnitude and persistence of deficits is not well understood. The impact of exposure in early development has been especially under-investigated. This study examined the impact of interpersonal trauma exposure (IPT) in the first years of life on childhood cognitive functioning. Methods Children (N = 206) participating in a longitudinal birth cohort study were assessed prospectively for exposure to IPT (physical or emotional abuse or neglect, sexual abuse, witnessing maternal partner violence) between birth and 64 months. Child intelligent quotient scores (IQ) were assessed at 24, 64, and 96 months of age. Race/ethnicity, gender, socioeconomic status, maternal IQ, birth complications, birthweight, and cognitive stimulation in the home were also assessed. Results IPT was significantly associated with decreased cognitive scores at all time points, even after controlling for sociodemographic factors, maternal IQ, birth complications, birthweight, and cognitive stimulation in the home. IPT in the first two years appeared to be especially detrimental. On average, compared to children not exposed to IPT in the first two years, exposed children scored one-half standard deviation lower across cognitive assessments. Conclusion IPT in early life may have adverse effects on cognitive development. IPT during the first two years may have particular impact, with effects persisting at least into later childhood.

    At ages 11 through 12 years, the Advisory Committee on Immunization Practices (ACIP) recommends that preteens receive 1 dose of tetanus, diphtheria, and acellular pertussis (Tdap) vaccine, 1 dose of meningococcal conjugate (MenACWY) vaccine, and 3 doses of human papillomavirus (HPV) vaccine. ACIP recommends administration of all age-appropriate vaccines during a single visit. ACIP also recommends that pre-teens and older adolescents receive an annual influenza vaccine as well as any overdue vaccines (e.g., varicella). To monitor vaccination coverage among persons aged 13-17 years, CDC analyzed data from the National Immunization Survey-Teen (NIS-Teen). This report highlights findings of that analysis. From 2011 to 2012, coverage increased for ≥1 Tdap vaccine dose (from 78.2% to 84.6%), ≥1 MenACWY vaccine dose (from 70.5% to 74.0%) and, among males, ≥1 HPV vaccine dose (from 8.3% to 20.8%). Among females, vaccination coverage estimates for each HPV vaccine series dose were similar in 2012 compared with 2011. Coverage varied substantially among states. Regarding Healthy People 2020 targets for adolescents, 36 states achieved targets for Tdap, 12 for MenACWY, and nine for varicella vaccine coverage. Large and increasing coverage differences between Tdap and other vaccines recommended for adolescents indicate that substantial missed opportunities remain for vaccinating teens, especially against HPV infection. Health-care providers should administer recommended HPV and meningococcal vaccinations to boys and girls during the same visits when Tdap vaccine is given. In addition, whether for health problems or well-checks, providers, parents, and adolescents should use every health-care visit as an opportunity to review adolescents' immunization histories and ensure that every adolescent is fully vaccinated.

    Neurodevelopmental evaluation in childhood provides an opportunity to study complex neurological compensation following documented neonatal brain injury, and furnishes important clinical information which may have an impact on patient care. We studied 152 term children treated with extracorporeal membrane oxygenation (ECMO) as neonates and who received routine neonatal neuroimaging and comprehensive neurodevelopmental evaluation at age 5 years. The cohort was divided into four groups based on an independent neuroimaging score: No lesion, N=88; Mild lesion, N=38; Moderate lesion, N=12; and Severe lesion, N=14. Standardized testing at age 5 included complete neuropsychological assessment, neurological evaluation, and assessment of motor function. All testing was conducted without knowledge of the neuroimaging score. The occurrence of disability by severity of neuroimaging was: No lesion=10%; Mild=13%; Moderate=33%; Severe=57%. The relative risk within the ECMO population for disability at age 5 after moderate or severe neonatal lesion was 4.3 (CI=1.0 to 17.5) and 11.7 (CI=3.3 to 41.3), respectively. The remaining non-disabled children who had moderate to severe lesions functioned within normal limits. Severity of neonatal neuroimaging was inversely associated with IQ scores, pre-academic skills, and neuromotor function. The effect size was small but the rank order was predictable. Our data identify in 5-year-old children an impact of brain lesion severity demonstrated on routine neonatal neuroimaging. The results indicate potential compensation following moderate and severe lesions, and suggest a subtle but consistent influence of even mild neonatal brain injury.

    Data from National Health and Nutrition Examination Survey for the years 2011-2012 were used to evaluate variability in the observed levels of 20 urinary metabolites of volatile organic compounds (VOCs) by age, gender, and race/ethnicity among children aged 6-11 years. Exposure to environmental tobacco smoke was positively associated with the levels of selected metabolites of acrylonitrile, 1,3-butadiene, cyanide, and propylene oxide in a dose-response manner. Levels of the selected metabolites of acrolein, acrylonitrile, 1,3-butadiene, styrene, toluene, and xylene decreased with increase in age. Levels of 1-bromopropane decreased with number of rooms in the house but the reverse was true for 1,3-butadiene, carbon-disulfide, and N,N-dimethylformamide. Levels of most of the 20 metabolites did not vary with gender. Non-Hispanic white children had higher adjusted levels of N-Acetyl-S-(3,4-dihydroxybutyl)-L-cysteine (DHBMA), N-Acetyl-S-(N-methylcarbamoyl)-L-cysteine (AMCC), and phenylglyoxylic acid (PGA) than non-Hispanic black children. Non-Hispanic white children had statistically significantly higher adjusted levels of N-Acetyl-S-(2-carbamoyl-2-hydroxyethyl)-L-cysteine (GAMA), trans, trans-Muconic acid (MU), and N-Acetyl-S-(N-methylcarbamoyl)-L-cysteine (AMCC) than non-Hispanic Asian children but statistically significantly lower levels of N-Acetyl-S-(n-propyl)-L-cysteine (BPMA) than non-Hispanic Asian children. Non-Hispanic Asian children had the lowest levels of 13 of the 20 metabolites among four major racial/ethnic groups but highest levels for three metabolites. For selected metabolites of acrolein, acrylamide, acrylonitrile-vinyl chloride-ethylene oxide, benzene, 1,3-butadien, crotonaldehyde, cyanide, ethylbenzene-styrene, and toluene, children had statistically significantly higher levels than nonsmoking adults. These results demonstrate how vulnerable children are to being exposed to harmful chemicals like VOCs in their own homes. PMID:26257031

    The diagnosis of hypogonadism in human males includes identification of low serum testosterone levels, and hence there is an underlying assumption that normal ranges of testosterone for the healthy population are known for all ages. However, to our knowledge, no such reference model exists in the literature, and hence the availability of an applicable biochemical reference range would be helpful for the clinical assessment of hypogonadal men. In this study, using model selection and validation analysis of data identified and extracted from thirteen studies, we derive and validate a normative model of total testosterone across the lifespan in healthy men. We show that total testosterone peaks [mean (2.5–97.5 percentile)] at 15.4 (7.2–31.1) nmol/L at an average age of 19 years, and falls in the average case [mean (2.5–97.5 percentile)] to 13.0 (6.6–25.3) nmol/L by age 40 years, but we find no evidence for a further fall in mean total testosterone with increasing age through to old age. However we do show that there is an increased variation in total testosterone levels with advancing age after age 40 years. This model provides the age related reference ranges needed to support research and clinical decision making in males who have symptoms that may be due to hypogonadism. PMID:25295520

    Spirometry is the most important tool in diagnosing pulmonary disease and is the most frequently performed pulmonary function test. Respiratory disease is also one of the greatest causes for morbidity and mortality on the Hopi Nation, but no specific reference equations exist for this unique population. The purpose of this study was to determine if population reference equations were necessary for these children and, if needed, to create new age and race-specific pulmonary nomograms for Hopi children. Two hundred and ninety-two healthy children, ages 4-13 years, attending Hopi Nation elementary schools in Arizona, were asked to perform spirometry for a full battery of pulmonary volumes and capacities of which the following were analyzed: forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1 ), FEV1 % (FEV1 /FVC), FEF25-75% and peak expiratory flow rate (PEFR). Spirometric data from Navajo children living in the same geographical region as the Hopi children were compared as well as spirometric data from common reference values used for other ethnic groups in the USA. Spirometry tests from 165 girls and 127 boys met American Thoracic Society quality control standards. We found that the natural log of height, body mass and age were significant predictors of FEV1 , FVC, and FEF25-75% in the gender-specific models and that lung function values all increased with height and age as expected. The predictions using the equations derived for Navajo, Caucasian, Mexican-American, African-American youth were significantly different (P ≤ 0.05) from the predictions derived from the Hopi equations for all of the variables across both genders, with the exceptions of Hopi versus Navajo FEV1 /FVC in the males and Hopi versus Caucasians FEF25-75% in the females. Thus it would appear for this population important to have specific formulae to provide more accurate reference values.

    Background: This study was planned to assess the dental caries status among disabled children as dental health is an integral part of general body health and this group is deprived of health care needs. Materials & Methods: A sample of 310 disabled children was gathered including 195- Hearing impaired, 115 – blind. Of which 226 were males and 84 were females. A study questionnaire was prepared to include demographic information and WHO oral health assessment form (1997) to record dental caries status.Data was analysed using student’s test and ANOVA test was used at p≤0.05. Results: The overall mean for DMFT scores for males and females was 2.11 (1.753) and 1.75 (1.275) respectively. Similarly overall mean for dft was 0.31 (0.254) for males and 0.27 (0.143) for females. Mean DMFT of blind students was more as compared to hearing impaired ones as 2.16 (2.005) and 1.80 (1.264) respectively. Age factor showed a significant increase in the mean DMFT scores with advancing age at p ≤ 0.001. Conclusion: Overall mean scores of caries was very high and it increased with increasing age. Blind children experienced more caries then hearing impaired children in permanent, whereas it was opposite in primary dentition. So there is urgent need of both comprehensive and incremental dental care for this subgroup of population. How to cite the article: Sanjay V, Shetty SM, Shetty RG, Managoli NA, Gugawad SC, Hitesh D.

    Purpose: To determine the rate of treatment deviations during combined modality therapy for rectal cancer in elderly patients aged 75 years and older. Methods and Materials: We reviewed the records of consecutively treated patients with rectal cancer aged 75 years and older treated with combined modality therapy at Massachusetts General Hospital and Brigham and Women's Hospital from 2002 to 2007. The primary endpoint was the rate of treatment deviation, defined as a treatment break, dose reduction, early discontinuation of therapy, or hospitalization during combined modality therapy. Patient comorbidity was rated using the validated Adult Comorbidity Evaluation 27 Test (ACE-27) comorbidity index. Fisher's exact test and the Mantel-Haenszel trend test were used to identify predictors of treatment tolerability. Results: Thirty-six eligible patients had a median age of 79.0 years (range, 75-87 years); 53% (19/36) had no or mild comorbidity and 47% (17/36) had moderate or severe comorbidity. In all, 58% of patients (21/36) were treated with preoperative chemoradiotherapy (CRT) and 33% (12/36) with postoperative CRT. Although 92% patients (33/36) completed the planned radiotherapy (RT) dose, 25% (9/36) required an RT-treatment break, 11% (4/36) were hospitalized, and 33% (12/36) had a dose reduction, break, or discontinuation of concurrent chemotherapy. In all, 39% of patients (14/36) completed {>=}4 months of adjuvant chemotherapy, and 17% (6/36) completed therapy without a treatment deviation. More patients with no to mild comorbidity completed treatment than did patients with moderate to severe comorbidity (21% vs. 12%, p = 0.66). The rate of deviation did not differ between patients who had preoperative or postoperative CRT (19% vs. 17%, p = 1.0). Conclusions: The majority of elderly patients with rectal cancer in this series required early termination of treatment, treatment interruptions, or dose reductions. These data suggest that further intensification of

    INTRODUCTION: Safe, effective weight loss with resolution of comorbidities has been convincingly demonstrated with bariatric surgery in the aged obese. They, however, lose less weight than younger individuals. It is not known if degree of weight loss is influenced by the choice of bariatric procedure. The aim of this study was to compare the degree of weight loss between laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients above the age of 50 years at 1 year after surgery. MATERIALS AND METHODS: A retrospective analysis was performed of all patients more than 50 years of age who underwent LSG or LRYGB between February 2012 and July 2013 with at least 1 year of follow-up. Data evaluated at 1 year included age, sex, weight, body mass index (BMI), mean operative time, percentage of weight loss and excess weight loss, resolution/remission of diabetes, morbidity and mortality. RESULTS: Of a total of 86 patients, 54 underwent LSG and 32 underwent LRYGB. The mean percentage of excess weight loss at the end of 1 year was 60.19 ± 17.45 % after LSG and 82.76 ± 34.26 % after LRYGB (P = 0.021). One patient developed a sleeve leak after LSG, and 2 developed iron deficiency anaemia after LRYGB. The remission/improvement in diabetes mellitus and biochemistry was similar. CONCLUSION: LRYGB may offer better results than LSG in terms of weight loss in patients over 50 years of age. PMID:27279392

    In this study, we assessed the effects of the prevaccination titer and age on the immunogenicity of a low dose of influenza vaccine in children less than 4 years of age. A total of 259 children received two vaccine doses (0.1 ml for 0-year-olds and 0.2 ml for children 1 year of age or older) 4 weeks apart during the 2005/2006 season. The hemagglutination inhibition antibody titers were measured before vaccination and 4 weeks after the first and second doses. The geometric mean titer, mean fold rise, seroresponse proportion (≥4-fold rise in titer), and seroprotection proportion (titer ≥1:40) were calculated for the prevaccination titer and age categories. A multivariate logistic regression analysis was performed using the seroresponse and seroprotection proportions as dependent variables and the prevaccination titer and age as explanatory variables. As for the seroresponse against the H1 antigen after the first dose, the adjusted odds ratios of the prevaccination titers (versus <1:10) were 2.2 (95% confidence interval, 0.8 to 5.8) at 1:10 to 1:20 and 0.14 (0.04 to 0.49) at ≥1:40. The corresponding figures for ages were 0.03 (0.01 to 0.07) for the 0-year-olds and 0.17 (0.08 to 0.34) for the 1-year-olds compared with the 2- to 3-year-olds (Ptrend < 0.001). Similar results were also obtained for the H3 and B strains. Significantly elevated odds ratios for seroprotection were observed with greater prevaccination titers and older ages for all strains. The prevaccination titer and age were independently associated with the antibody response in young children. The immune response was weaker in the younger children and those without preexisting immunity.

    The Attitude Toward Own Aging Subscale (ATOA) is a frequently used measure of subjective aging. Although ATOA in midlife might assume a preparatory role for psychosocial adjustment in old age, research has been dominated by a focus on older adults. To enable a comparison of developmental trajectories of ATOA between middle-aged and young-old adults, we tested measurement invariance between age groups and over a 12-year study period. In addition, personality variables, health dimensions, and sociodemographic variables were investigated as predictors of developmental trajectories of ATOA. Data came from the Interdisciplinary Longitudinal Study of Adult Development (ILSE) with 2 birth cohorts (1930-1932: n = 500; 1950-1952: n = 501) followed over 12 years. Data analyses were conducted with confirmatory factor analysis for ordered-categorical variables and latent growth models. Support for the assumption of partial measurement invariance of ATOA was found in each age group, but not between age groups. Latent growth models revealed a steady decline in ATOA for young-old individuals, whereas ATOA trajectories in midlife were characterized by interindividual variation. Health variables predicted level of ATOA in the young-old. In midlife ATOA were shaped by a variety of factors. Future studies should be conducted with an awareness of differential item functioning of the ATOA scale across age groups. Furthermore, our results point to a greater modifiability of aging attitudes in middle-aged compared with young-old individuals, thus highlighting the importance of the midlife years in shaping developmental trajectories into old age.
