    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

    2008-01-01

    We have performed an unbiased global search for the geometries of low-lying Gen clusters in the size range of 30⩽n⩽39 using genetic algorithm incorporated with a tight-binding model. Density functional theory calculations were carried out to further optimize the isomer structures. Gen (n=30-39) clusters prefer the motif of supercluster structures stacked by several stable subunits such as Ge10 and Ge6, connecting via a few bridging atoms. Size-dependent cluster properties such as binding energy, HOMO-LUMO gaps, and ionization potentials were discussed and compared with experiments.

  12. 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.

  19. Breast cancer screening outcomes in women ages 40-49: clinical experience with service screening using modern mammography.

    PubMed

    Sickles, E A

    1997-01-01

    The several randomized controlled trials (RCTs) of breast cancer screening among women of ages 40 to 49 now collectively show a statistically significant reduction in breast cancer mortality. However, there have been numerous recent advances in mammography, such that it now is demonstrably better than when the RCTs were conducted. The use of surrogate measures of screening efficacy (tumor size, lymph node status, cancer stage), readily derived from modern service screening programs, demonstrates how the improved mammography of the 1990s should produce a greater degree of mortality reduction among women ages 40-49 than that already demonstrated in the RCTs. Indeed, these surrogate measures of mortality reduction are as favorable for women of ages 40-49 and 65+ as they are for women of ages 50-64, strongly suggesting that, since modern service screening is accepted as effectively reducing mortality among women of ages 50-64, it should also effectively reduce mortality among women in the 40-49 and 65+ age groups.

  20. Effect of D-amino acids at Asp{sup 23} and Ser{sup 26} residues on the conformational preference of A{beta}{sub 20-29} peptides

    The effects of D-amino acids at Asp{sup 23} and Ser{sup 26} residues on the conformational preference of {beta}-amyloid (A{beta}) peptide fragment (A{beta}{sub 20-29}) have been studied using different spectroscopic techniques, namely vibrational circular dichroism (VCD), vibrational absorption, and electronic circular dichroism. To study the structure of the A{beta}{sub 20-29}, [D-Asp{sup 23}]A{beta}{sub 20-29}, and [D-Ser{sup 26}]A{beta}{sub 20-29} peptides under different conditions, the spectra were measured in 10 mM acetate buffer (pH 3) and in 2,2,2-trifluoroethanol (TFE). The spectroscopic results indicated that at pH 3, A{beta}{sub 20-29} peptide takes random coil with {beta}-turn structure, while [D-Ser{sup 26}]A{beta}{sub 20-29} peptide adopts significant amount of polyproline II (PPII) type structure along with {beta}-turn contribution and D-Asp-substituted peptide ([D-Asp{sup 23}]A{beta}{sub 20-29}) adopts predominantly PPII type structure. The increased propensity for PPII conformation upon D-amino acid substitution, in acidic medium, has important biological implications. In TFE, A{beta}{sub 20-29}, [D-Asp{sup 23}]A{beta}{sub 20-29}, and [D-Ser{sup 26}]A{beta}{sub 20-29} peptides adopt 3{sub 10}-helix, {alpha}-helix, and random coil with some {beta}-turn structures, respectively. The VCD data obtained for the A{beta} peptide films suggested that the secondary structures for the peptide films are not the same as those for corresponding solution and are also different among the A{beta} peptides studied here. This observation suggests that dehydration can have a significant influence on the structural preferences of these peptides.

    Paullinia pinnata L. (Sapindaceae) is an endemic West African plant that is extensively used in traditional medicine to treat various diseases. Previous phytochemical analysis by various groups led to the isolation of several novel lupene-based triterpenene derivatives along with other classes of compounds. As part of our continued phytochemical studies on the roots of this plant, we have now identified yet another novel triterpene, 6a-(3'-methoxy-4'-hydroxybenzoyl)-lup-20(29)-ene-3-one. The identification of the compound through comprehensive spectroscopic studies is discussed. PMID:25973476

    The authors defined the morbidity index of late epilepsy (MI) on the ground of notified cases in the population aged over 20 years (with first seizure past the age of 20 years) comprising 228273 individuals (125453 living in towns and 102820 living in villages) in the years 1979-1980. The index was calculated per 1000 of the population. The general index was 2.23 (males--2.77; females--1.72). The value of the index was highest in the age group 20-29 years (3.75) and 40-49 years (2.58) in males, and in females this value was also at its peaks in these age groups (2.63 and 1.93, respectively). In the whole population the index had also two peaks in these age groups: 3.21 and 2.55 respectively. In the urban population the general index was 2.33 (2.77 in males and 1,91 in females) being again highest in the age groups 20-29 and 40-49 years. Similar peaks were found in these age groups in the urban male and female populations. In the rural population the general index was 2.11 (males 2.77, females 1.49) and the peaks were in the age groups 20-29 and 30-39 years. In males these peaks were in the age groups 20-29 and 40-49, and in females in the groups 20-29 and 30-39 years. The lowest index value was in the age group over 60 years in the whole population (1.22), in the urban population (1.62 and in the rural population (0.91). In further studies on epilepsy the method of active search for epilepsy cases with full clinical and epidemiological analysis is being used.

    Three compounds were isolated from Maytenus acanthophylla Reissek (Celastraceae): the pentacyclic triterpenes lup-20(29)-en-3β-ol (lupeol, 1) and 3β-lup-20(29)-en-3-yl acetate (2) and the carbohydrate 1,2,3,4,5,6-hexa-O-acetyldulcitol (3); lupeol was also isolated from Xylosma flexuosa. The compounds' structures were elucidated by spectroscopic and spectrometric analysis. Compound 1 acts as an energy transfer inhibitor, interacting with isolated CF₁ bound to thylakoid membrane, and dulcitol hexaacetate 3 behaves as a Hill reaction inhibitor and as an uncoupler, as determined by polarography. Chlorophyll a (Chl a) fluorescence induction kinetics from the minimum yield F₀ to the maximum yield F(M )provides information of the filling up from electrons coming from water to plastoquinone pool with reducing equivalents. In this paper we have examined the effects of compounds 1 and 3 on spinach leaf discs. Compound 1 induces the appearance of a K-band, which indicates that it inhibits the water splitting enzyme. In vivo assays measuring the fluorescence of chl a in P. ixocarpa leaves sprayed with compound 1, showed the appearance of the K-band and the PSII reaction centers was transformed to "heat sinks" or silent reaction centers unable to reduce Q(A). However, 3 also induced the appearance of a K band and a new band I appears in P. ixocarpa plants, therefore it inhibits at the water splitting enzyme complex and at the PQH₂ site on b₆f complex. Compounds 1 and 3 did not affect chlorophyll a fluorescence of L. perenne plants.

    In cancer screening, it is essential to undertake effective screening with appropriate methodology, which should be supported by evidence of a reduced mortality rate. At present, mammography is the only method for breast cancer screening with such evidence. However, mammography does not achieve sufficient accuracy in breasts with high density at ages below 50. Although ultrasonography achieves better accuracy in Breast Cancer detection even in dense breasts, the effectiveness has not been verified. We have planned a randomized controlled trial to assess the effectiveness of ultrasonography in women aged 40-49, with a design to study 50,000 women with mammography and ultrasonography (intervention group), and 50,000 controls with mammography only (control group). The participants are scheduled to take second round screening with the same modality 2 years on. The primary endpoints are sensitivity and specificity, and the secondary endpoint is the rate of advanced breast cancers.

    Mammographic density is a strong risk factor for breast cancer, but its potential application in risk management is not clear, partly due to uncertainties about its interaction with other breast cancer risk factors. We aimed to quantify the impact of mammographic density on breast cancer risk in women aged 40-49 at intermediate familial risk of breast cancer (average lifetime risk of 23%), in particular in premenopausal women, and to investigate its relationship with other breast cancer risk factors in this population. We present the results from a case-control study nested with the FH01 cohort study of 6,710 women mostly aged 40-49 at intermediate familial risk of breast cancer. One hundred and three cases of breast cancer were age-matched to one or two controls. Density was measured by semiautomated interactive thresholding. Absolute density, but not percent density, was a significant risk factor for breast cancer in this population after adjusting for area of nondense tissue (OR per 10 cm(2) = 1.07, 95% CI 1.00-1.15, p = 0.04). The effect was stronger in premenopausal women, who made up the majority of the study population. Absolute density remained a significant predictor of breast cancer risk after adjusting for age at menarche, age at first live birth, parity, past or present hormone replacement therapy, and the Tyrer-Cuzick 10-year relative risk estimate of breast cancer. Absolute density can improve breast cancer risk stratification and delineation of high-risk groups alongside the Tyrer-Cuzick 10-year relative risk estimate.

    The Italian Mammography Screening Network (GISMa) held a national consensus conference in Bologna, May 25-26 2006. The large panel of participants included national experts in fields related to breast cancer and screening issues. The final aim was the production of a consensus statement which might become a standard reference for Italy. The consensus document (http://www.gisma.it) states that full national coverage by organized screening for breast (age 50-69), cervical and colorectal cancer is a priority, before any extension of organized mammography screening to younger or older age groups may be considered. If adequate resources are available, extension of organized screening for breast cancer until age 74 is recommended, at least for regular attenders until age 69. Extension of organized screening to women aged 40-49 may be considered at some conditions: (a) that resources are available, (b) that a 1-year interval is adopted, (c) that proper information of the limitations of screening is given to participants and (d) that priority is given to age 45-49.

    3,4- Seco-lup-20(29)-en-3-oic acid ( 1), a rare triterpene, was isolated from Wrightia tinctoria R.Br (Family: Apocyanaceae). It appeared promising to study the structural chemistry of this compound because of its unique bio activity. X-ray diffraction analysis demonstrated that this compound consists of three six membered rings and one five membered ring. The first six membered ring (A) is in the twist boat form while the remaining two six membered rings (B, C) are in the chair form. The crystal of this compound belongs - to the monoclinic crystal system and space group P2 1. Lattice constituents are as follows: a = 13.074(6) Å, b = 11.972(5) Å, c = 17.394(7) Å; α = 90.00°, β = 98.20(13)°, γ = 90.00°; V = 2695(2) Å 3, d = 1.094 Mg/m 3, Z = 4. The optimized geometry of the reported molecule has been calculated with the DFT/B3LYP theory using 6-31G(d,p) basis set.

    This study evaluated the antimicrobial effect of 3β,6β,16β-trihydroxylup-20(29)-ene (CLF1), a triterpene isolated from Combretum leprosum Mart., in inhibiting the planktonic growth and biofilms of Gram positive bacteria Streptococcus mutans and S. mitis. The antimicrobial activity was assessed by determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The antibiofilm potential was determined by quantifying total biomass and enumerating biofilm-entrapped viable bacteria. In addition, the acute toxicity of CLF1 on Artemia sp. nauplii was also determined. The results showed that CLF1 was able in inhibiting the growth of S. mutans and S. mitis with MIC and MBC of 7.8 μg/mL and 15.6 μg/mL, respectively. CLF1 was highly effective on biofilms of both bacteria. Only 7.8 μg/mL CLF1 was enough to inhibit by 97% and 90% biomass production of S. mutans and S. mitis, respectively. On the other hand, such effects were not evident on Gram negative Pseudomonas aeruginosa and Klebsiella oxytoca. The toxicity tests showed that the LC50 of CLF1 was 98.19 μg/mL. Therefore, CLF1 isolated from C. leprosum may constitute an important natural agent for the development of new therapies for caries and other infectious diseases caused by S. mutans and S. mitis.

CLF1 was highly effective on biofilms of both bacteria. Only 7.8 μg/mL CLF1 was enough to inhibit by 97% and 90% biomass production of S. mutans and S. mitis, respectively. On the other hand, such effects were not evident on Gram negative Pseudomonas aeruginosa and Klebsiella oxytoca. The toxicity tests showed that the LC50 of CLF1 was 98.19 μg/mL. Therefore, CLF1 isolated from C. leprosum may constitute an important natural agent for the development of new therapies for caries and other infectious diseases caused by S. mutans and S. mitis.

    The aims of the study were to [1] investigate the performance trends at the 'Zurich 12-h Swim' in Switzerland from 1996 to 2010; and [2] determine the gender difference in peak performance in ultraendurance swimming. In total, 113 male and 53 female swimmers competed in this indoor ultraendurance event while swimming in a heated pool. The number of male participants significantly increased (r² = 0.36, P = 0.04) over time while the participation of females remained unchanged (r² = 0.12, P = 0.26). In the age group < 19 years, the male swimmers achieved a significantly greater distance than the females (32.7 km vs. 21.9 km, respectively) (P < 0.05). In the older age groups (20-29 years, 30-39 years, 40-49 years, and 50-59 years, respectively) was no gender difference in swimming performances (P < 0.05). The best performance was achieved in the age groups 30-39 years and 40-49 years for both genders, respectively. The athletes in the age groups < 19 years, 20-29 years and 50-59 years in females were significantly slower than the athletes in the age group 30-39 years and 40-49 years (P < 0.05). For the males, the athletes in the age group 30-39 years were significantly faster than the athletes in the age group < 19 years. The annual best performance was not significantly different between males and females (38.3 ± 2.9 km vs. 34.4 ± 8.2 km, respectively) (P < 0.05). The best male and female swim performances remained unchanged across the years. Females are able to achieve a similar swim performance in an indoor ultra-endurance swim event of ~40 km. Further studies are needed to investigate whether females are able to achieve similar or even better performances than males in openwater ultra-swimming events such as 'Channel Swimming'.

    Plumbago zeylanica, a traditional Indian herb is being used for the therapy of rheumatism and has been approved for anti-tumor activity. However, the molecular mechanisms involved in the biological action are not very well understood. In this study, the anti-invasive activities of P. zeylanica methanolic extract (PME) and pure compound 3β-hydroxylup-20(29)-ene-27,28-dioic acid (PZP) isolated from it are investigated in vitro. PME and PZP were noted to have the ability to induce apoptosis as assessed by flow cytometry. Further, the molecular mechanism of apoptosis induced by PME and PZP was found by the loss of mitochondrial membrane potential with the down regulation of Bcl-2, increased expression of Bad, release of cytochrome c, activation of caspase-3 and cleavage of PARP leading to DNA fragmentation. Importantly, both PME and PZP were observed to suppress MDA-MB-231 cells adhesion to the fibronectin-coated substrate and also inhibited the wound healing migration and invasion of MDA-MB-231 cells through the reconstituted extracellular matrix. Gelatin zymography revealed that PME and PZP decreased the secretion of matrix metalloproteinases-2 (MMP-2) and metalloproteinases-9 (MMP-9). Interestingly both PME and PZP exerted an inhibitory effect on the protein levels of p-PI3K, p-Akt, p-JNK, p-ERK1/2, MMP-2, MMP-9, VEGF and HIF-1α that are consistent with the observed anti-metastatic effect. Collectively, these data provide the molecular basis of the anti-proliferative and anti-metastatic effects of PME and PZP.

    Administration of the compound triterpene 3β, 6β, 16β-trihidroxilup-20(29)-ene (TTHL) resulted in antinociceptive activity in several pain models in mice. Because pain and epilepsy have common mechanisms, and several anticonvulsants are clinically used to treat painful disorders, we investigated the anticonvulsant potential of TTHL. Behavioral and electrographic recordings revealed that pretreatment with TTHL (30 mg/kg; i.g.) increased the latencies to the first clonic seizure to the tonic-clonic and reduced the duration of the generalized seizures induced by the GABA(A) receptor antagonist PTZ (80 g; i.p.). The TTHL pretreatment also protected against PTZ-induced deleterious effects, as characterized by protein carbonylation, lipid peroxidation, [(3)H] glutamate uptake and the inhibition of Na(+),K(+)-ATPase (subunits α(1) and α(2)/α(3)). Although TTHL did not exhibit DPPH, ABTS radical scavenging activity per se and does not alter the binding of [(3)H]flunitrazepam to the benzodiazepinic site of the GABA(A) receptor, this compound was effective in preventing behavioral and EEG seizures, as well as the inhibition of Na(+),K(+)-ATPase induced by ouabain. These results suggest that the protection against PTZ-induced seizures elicited by TTHL is due to Na(+),K(+)-ATPase activity maintenance. In fact, experiments in homogenates of the cerebral cortex revealed that PTZ (10 mM) reduced Na(+),K(+)-ATPase activity and that previous incubation with TTHL (10 μM) protected against this inhibition. Collectively, these data indicate that the protection exerted by TTHL in this model of convulsion is not related to antioxidant activity or GABAergic activity. However, these results demonstrated that the effective protection of Na(+),K(+)-ATPase elicited by this compound protects against the damage due to neuronal excitability and oxidation that is induced by PTZ.

    The IgG antibody levels directed against fHbp and NadA, two potential vaccine antigens for Neisseria meningitidis, were examined in order to investigate the extent of natural immunisation against these antigens in different age groups. As a comparison, the IgG antibody levels against Haemophilus influenzae type b were examined. In the two youngest age groups, below 10 years of age, relatively low levels of both anti-fHbp and anti-NadA were measured. A 15-fold higher geometric mean concentration of anti-fHbp was noted in the age group 20-29 years as compared to the age group 15-19 years. The peak concentration was found at 30-39 years, followed by decreased levels with age. Anti-NadA showed a certain increase up to 9 years followed by an even increase up to 40-49 years.

    In order to assess changes in knowledge of HIV/AIDS and attitude for People With HIV/AIDS (PWA), interview surveys (Dec. 1992, Jan. 1994, Jan. 1995) were carried out annually on random samples of the general public in Tokyo, age between 15-69 years. In total, 4,270 individuals were sampled, with an average response rate of 63.2%. Answers were scored and classified in 12 sex and age sub-groups. Additionally, correlations between scores of questions and social indices were analyzed. The results of the study are as follows: 1) The 15-19, 20-29 and 30-39 age groups showed higher scores on knowledge about HIV transmission modes. During the entire study period, the score increased in 7 groups, but decreased in 5 groups. 2) The 30-39 and 40-49 age groups showed higher scores on knowledge about HIV antibody test. During the period, the score increased in 11 groups, and among them 6 groups showed statistically significant (p < 0.05) increases. However, the score decreased in 9 groups at the third survey. 3) The 15-19, 20-29 and 30-39 age groups showed higher scores on acceptable attitudes for PWA. During the period, the score increased in all groups, and among them 3 groups showed statistically significant (p < 0.05) increases. 4) Rank correlations between two scores-knowledge quantity about the transmission modes and acceptable attitudes for PWA-were positive (0.2 < R) and statistically significant (p < 0.05) in 11 groups at the first survey, 9 groups at the second, and 6 groups at the third. 5) During the entire study period, 6 groups showed positive correlations (0.7 < R) between two changes: (1) score of knowledge about the transmission modes and (2) score of acceptable attitudes. 6) During the entire study period, 10 groups showed positive correlations (0.7 < R) between two changes: (1) score of acceptable attitudes and (2) number of newspaper articles regarding acceptance or discrimination of the PWA. 7) Knowledge about HIV/AIDS in the general public in Tokyo showed

    This investigation was aimed to detect the carotid elasticity in normal adults by use of echo-tracking (ET) technique. The stiffness parameter (beta), pressure-strain elasticity modulus (Ep), arterial compliance (AC), argumentation index (AI) and one-point pulse wave velocity (PWV beta) of carotid in 145 normal adults with the average age of 47.0 were calculated. The population were divided into five groups according to age: 20-29 y, 30-39 y,40-49 y, 50-59 y and > or = 60 y. The elasticity parameters between left and right side, between male female and between different age groups were compared using SAS 6.12 statistic software. There was no difference in carotid elasticity regarding the side and gender. The carotid beta, Ep, AI and PWV beta were noted to increase with age while AC was noted to decrease with age. The carotid elasticity was found to correlate with age significantly, but not with side and gender. This change can be detected by ET technique.

    We conducted a cross-sectional seroepidemiological study in 2012-2013 to determine the seroprevalence of varicella-zoster virus (VZV) in adolescents and adults living in Korea, where varicella vaccination has been recommended universally at age 12-15 months since 2005. Residual serum samples were collected from 1196 healthy adults and adolescents aged ⩾10 years between November 2012 and March 2013. The fluorescent antibody to membrane antigen (FAMA) test and enzyme-linked immunosorbent assay (ELISA) were performed to determine the seroprevalence of VZV. The seroprevalences of VZV were compared between six age groups: 10-19, 20-29, 30-39, 40-49, 50-59, and ⩾60 years. The seroprevalence of VZV in the entire study cohort was 99·1% according to the FAMA test and 93·1% as determined by ELISA. The seroprevalences of the six age groups were as follows: 96·0%, 99·5%, 99·5%, 99·5%, 100%, and 100%, respectively, by the FAMA test, and 83·3%, 93·0%, 93·0%, 97·5%, 94·5%, and 97·5%, respectively, by ELISA. Seroprevalence increased significantly with age (P < 0·001); moreover, the seroprevalence in subjects aged 10-19 years was significantly lower than in other age groups (P < 0·001), as measured by both the FAMA test and ELISA. Thus, strategies to increase protective immunity against VZV in teenagers are necessary.

    The objectives of this study were to develop a specific formula to estimate age in a Brazilian adult population and to compare the original formula from Cameriere to this Brazilian formula. The sample comprised 1,772 periapical radiographs from 443 subjects (219 men, 224 women) that were organized into 12 groups according to sex (men or women) and age (20-29, 30-39, 40-49, 50-59, 60-69, and 70 years and older). The films were analyzed using the criteria described by Cameriere et al. (2004) and Adobe Photoshop®. We obtained a mean error of 8.56 (SD = 5.80) years for tooth 13, 7.99 (SD = 5.78) years for tooth 23, 8.38 (SD = 6.26) years for tooth 33, and 8.20 (SD = 6.54) years for tooth 43. When teeth were combined in the analysis, we observed lower mean errors. The Brazilian formula developed from this sample group was more accurate than Cameriere's formula. However, other factors must be considered to improve age estimates in adults. PMID:25590504

    Two hundred and sixty-nine apparently healthy Kuwaiti men, aged 20-49, from 800 randomly selected Kuwaiti families, were examined for cardiovascular fitness and risk factors for coronary heart diseases (CHD). The risk factors were examined by exercise stress test on Quinton-2000 ECG monitor and treadmill Q-model 24-26, Bruce protocol, along with Ergo-oxyscreen, by laboratory tests of fasting blood lipid levels, and by interview using a questionnaire. The sample was stratified into three age groups, 20-29, 30-39, and 40-49. For the entire sample, the results showed that a number of the investigated factors were significantly correlated with the duration of treadmill exercise time. Univariate analysis indicated that performance was inversely correlated with age, cholesterol levels, cholesterol:HDL ratio, triglycerides and uric acid, weight, body-build indexes, body density, resting heart rate, blood pressure (BP), personal history of CHD, and smoking habits. Most of the observed significant correlations were particularly pronounced in the younger age groups, 20-39 years. In this group, significant results in the analysis of variance were found between the treadmill performance time and a number of risk factors, including: cholesterol levels, age, cholesterol:HDL ratios, triglycerides, uric acid, heart rate, elevated systolic blood pressure, and obesity.

    Data from the 1999-2004 National Health and Nutrition Examination Survey were used to describe the distribution of cardiorespiratory fitness and its association with obesity and leisure-time physical activity (LTPA) for adults 20-49 years of age without physical limitations or indications of cardiovascular disease. A sample of 7,437 adults aged 20-49 years were examined at a mobile examination center. Of 4,860 eligible for a submaximal treadmill test, 3,250 completed the test and were included in the analysis. The mean maximal oxygen uptake ( max) was estimated as 44.5, 42.8, and 42.2 mL/kg/minute for men 20-29, 30-39, and 40-49 years of age, respectively. For women, it was 36.5, 35.4, and 34.4 mL/kg/minute for the corresponding age groups. Non-Hispanic black women had lower fitness levels than did non-Hispanic white and Mexican-American women. Regardless of gender or race/ethnicity, people who were obese had a significantly lower estimated maximal oxygen uptake than did nonobese adults. Furthermore, a positive association between fitness level and LTPA participation was observed for both men and women. These results can be used to track future population assessments and to evaluate interventions. The differences in fitness status among population subgroups and by obesity status or LTPA can also be used to develop health policies and targeted educational campaigns.

    The conventional lumbar separation was performed by removing soft tissue, subsidiary structures and leaving only the vertebral body. The vertebral body was cut into two halves along the median sagittal plane, keeping the upper and lower end plates of each half, which were subsequently used for biomechanical, morphological and density experiments. From the age of 20-29 to 30-39 years, both the horizontal trabecular thickness (Tb.Th) and vertical Tb.Th decreased; the horizontal and vertical Tb.Sp increased; the plate-like trabecular Tb.Th decreased; the apparent density and volume ratio decreased; and the elastic modulus and the ultimate stress decreased; with all changes being statistically significant (p < 0.01). Similar trends were obtained from ages 40-49 to 50-59, although the changes were not significant (p > 0.05), except for the reduction in ultimate stress (p < 0.05). With aging, the collagen cross-linking capacity declined; the thicknesses of the collagen fibrils were variable, ranging from almost the same to loose, sparse or disordered thickness; and the finer collagen fibrils between the thick filaments were disorganized. In males aged from 20 to 59 years old, the horizontal and vertical Tb.Th and the plate-like Tb.Th of the vertebral body decreased, while the horizontal and vertical Tb.Sp increased. Additionally, the density, elastic modulus and the ultimate stress of the cancellous bone decreased with age. Thus, the associated changes of bone microstructure, density and biomechanics with age may lead to an increased risk of osteoporosis and fracture.

    The aim of this research was to evaluate age-related changes in the smile of Brazilian women. The sample consisted of 249 Brazilian women who had not undergone previous orthodontic treatment or facial surgery. They were divided into four groups, according to age: G1 (20-29), G2 (30-39), G3 (40-49) and G4 (50 or older). Standardized front view photographs were taken while smiling and at rest. Measurements were evaluated by ANOVA and post-hoc Tukey. The Chi-square test was applied for qualitative variables. Upper lip thickness at rest and exposure of upper incisors on smiling decreased with age. Most individuals (60.9%) exhibited a medium smile. High smiles were more often seen in G1 (45%) and less frequently in G4 (18.8%), whereas the opposite occurred with the low smile, i.e., G4 (21.9%) and G1 (6.7%). Variations among the groups were observed in the transverse exposure of the teeth on smiling. In G1 and G3, there was a balance between tooth exposures, so that the teeth were exposed as far as the premolars and/or molars. Most of the women (56.3%) in G2 exposed their teeth as far as the first molars on smiling, whereas most of those (40.6%) in G4 exposed their teeth only as far as the first premolars on smiling. As age increased, there was decreased exposure of the upper incisors, decreased upper lip thickness and lower exposure of teeth vertically and transversely.

    The aim of this prospective study was to quantify the display of the dentition through the soft tissue frame during speech using videography for different age groups. Two hundred and sixty-one subjects were initially screened and were divided into five groups: group 1 (G1) (15-19 years), G2 (20-29 years), G3 (30-39 years), G4 (40-49 years), and G5 (≥ 50 years). Groups were also made on the basis of gender and history of orthodontic treatment. Video equipment was used to capture video and each frame was analysed out of which two frames that best represented the maximal display of maxillary incisors (MDMI) during speech and the widest transverse display of dentition (WTDD) during speech were selected. The data obtained was analysed using one-way analyses of variance with Fisher's least significant difference post hoc test. MDMI and WTDD were found to be highly significant during speech across all age groups (P < 0.05). G1-G3 displayed approximately similar levels of maxillary incisor (P > 0.05) but was greater (P < 0.05) than G4 and G5. The buccal corridor showed significant differences as a function of age (P < 0.05). Orthodontic treatment had a significant impact on the display of the maxillary incisors (P < 0.05) but not on the buccal corridors (P > 0.05). Mandibular incisor display was relatively stable across G1-G3, increasing only for G4 and G5. It appears that the maximum display of maxillary incisors decreases with age and the decline is particularly rapid with increasing age. Females tend to display more teeth both in the transverse and vertical directions.

    Objective: This study was designed to investigate radiographically the effects of age and external irritating stimuli on the morphology and thickness of the pulp chamber ceiling and floor in mandibular molars. Materials and Methods: A total of 234 panoramic radiographs were recruited and 494 mandibular molars were examined in this study. The sample was divided into six age groups: Group 1, <20 years; Group 2, 20-29 years; Group 3, 30-39 years; Group 4, 40-49 years; Group 5, 50-59 years and Group 6, >60 years. Each group was subdivided into two subgroups with regard to the tooth condition (intact or non-intact teeth). Four distances, two angles and two ratios were measured, in order to estimate the dimensions of the pulp chamber and the thickness of the pulp chamber ceiling and floor. Results: The thickness of the pulp chamber ceiling and floor increased significantly from Group 1 to 6. The pulp chamber floor angle presented progressive sharpness from Group 1 to 6 whereas the pulp chamber ceiling angle presented progressive bluntness from Group 1 to 5 and sharpness from Group 5 to 6. Significant differences were identified in the thickness of the pulp chamber ceiling, the thickness of the pulp chamber floor and the ceiling-floor distance between intact and non-intact teeth. Conclusion: Based on those results, there are differences in the location of secondary dentin formation between the two pulp chamber walls. Age is related to diminished pulp chamber size. The increase rate of the pulp chamber ceiling thickness is similar to that of the pulp chamber floor thickness. Furthermore, external irritating stimuli have an effect on the pulp chamber dimensional changes. PMID:24966753

    Human adipose tissue-derived mesenchymal stem cells (AT-MSCs) from various sites are applied in tissue engineering and cell therapy. The condition of AT-MSCs depends on the donor's age, body mass index (BMI), and gender. AT-MSCs from 66 human donors were analyzed, and the cells were sorted according to donor age (10-19 years: n = 1; 20-29 years: n = 5; 30-39 years: n = 12; 40-49 years: n = 22; 50-59 years: n = 12; 60-69 years: n = 9, and 70 years or older: n = 5), BMI (under 25, 25-30, and over 30), and gender (19 males and 48 females). Additionally, AT-MSCs were compared to bone marrow MSCs and chorionic tissue-derived MSCs. We measured the MSC yield, growth rate, colony-forming units, multipotency, and surface antigens. AT-MSC proliferation was greater in cells isolated from individuals aged less than 30 years compared to the proliferation of AT-MSCs from those over 50 years old. BMI was correlated with osteogenic differentiation potency; increased BMI enhanced osteogenesis. Adipogenic differentiation was more strongly induced in cells isolated from donors aged less than 30 years compared to those isolated from other age groups. Also, a BMI above 30 was associated with enhanced adipogenic differentiation compared to cells isolated from individuals with a BMI below 25. Bone marrow MSCs were strongly induced to differentiate along both osteogenic and adipogenic lineages, whereas AT-MSCs predominantly differentiated into the chondrogenic lineage. Therefore, the type of regeneration required and variations among potential donors must be carefully considered when selecting MSCs for use in applied tissue engineering or cell therapy.

    Objective: A study was carried out to analyze the efficacy and practical application for age estimation using digital panoramic radiograph to exploit image analysis to obtain metric measurement of morphological parameters of permanent mandibular first molar on Sulaimani population. Materials and Methods: In the present study a population of known age and sex was studied and subjected to digital panoramic radiographic examination. The correlation between the reduction of coronal pulp cavity and chronological age was examined in a sample of 96 individuals distributed into four age groups: 20-29 years (29 cases), 30-39 years (29 cases), 40-49 years (26 cases) and 50-59 years (12 cases). The height (mm) of the crown (CH = coronal height) and the height (mm) of coronal pulp cavity (CPCH = coronal pulp cavity height) of 96 of first molars from all subjects was measured. The tooth–coronal index (TCI) after Ikeda et al. was computed for each tooth and regressed on real age. Results: ANOVA was used to show the strength of relation between the age and TCI (P = 0.0000). The correlation coefficient (r2) was 0.49, which mean there is strong negative linear regression between age and TCI with the r2, regarding predicting age using TCI value, after the following equation calculated, Predicted age = 3.78 – (0.064 TCI) showed that there is no significant difference between real age and estimated age. Conclusion: There is a strong negative liner relationship between TCIs of mandibular first molars with chronological age of Sulaimani population, and age of individuals can therefore be estimated with a good degree of accuracy using regression equations.

    The records of 255 cyanide poisoning deaths obtained from National Forensic Service (NFS) headquarters, located in Seoul of Korea, from 2005 to 2010 were retrospectively reviewed. The mean age was 41.88 ± 13.09 and range was 6~80 years (unknown in seven cases). The number of deaths of males and females were 200 and 53, respectively (unknown in two cases). The largest number of cases occurred in people aged 40-49 years (81 cases, 31.8%), followed by the age groups 30~39 years (51 cases, 20%), 50~59 years (44 cases, 17.2%) and 20~29 years (43 cases, 16.9%). The total number of deaths among other age groups (below 10, 10~19, 60~69, 70~79, over 80 years and unknown) were 36, representing only 14.1%. Of all cyanide poisoning deaths, 97.3% were due to suicide, and 14.5% of the total number who died received medical treatment. The most frequent site for ingestion was the person's own residence (120 cases, 47.1%) and the route of administration was mainly oral (252, 98.8%). From the total of 255 cyanide poisoning cases, white powders were submitted for analysis in 92 cases. Potassium cyanide and sodium cyanide occupied 51 and 41 cases, respectively. This study showed that poisoning deaths due to cyanide are one of the continuously reported public health problems in Korea. Enforcement of regulations and safety education to prevent cyanide poisoning should be carried out by the government. PMID:24278610

    This study tested a theoretical model that views female employment and fertility decisions as jointly determined by biologic, sociologic, economic, and demographic factors that determine the circumstances of individual women, families, and the labor market. The data were drawn from a multistage stratified sample of 1926 married women of childbearing age in southern Philippines. The independent variables analyzed included the exogenous wage rates of both the wife and husband, the age of the wife, the number of children ever born per year of marriage, and residence (urban or rural). Also analyzed were the social variables of time conflict, normative conflict, work commitment, and wife's relative dominance in household decision making. An exogenous change in female wage rates increased the percent of time spent in paid employment but had an insignificant effect on fertility. In contrast, a change in the male wage rate reduce female employment and current fertility. Women in municipal poblacions had lower current fertility and significantly higher labor force participation than women in rural or urban settings. Women who perceived that children interfere with work were more likely to bear a child in the study period and less likely to participate in the labor force. The husband's attitude toward female employment reduced labor force participation, but did not increase current fertility. Finally, women who play a major role in household decision making had both increased labor force participation and increased fertility. There was some variation in these trends by age cohort. A positive coefficient of the female wage on fertility was observed among women 20-29 and 40-49 years, while a negative coefficient existed for women 30-39 years. It is concluded that a common set of economic and social factors jointly determine current female employment and fertility decisions.

    AIM To investigate the incidence and general characteristics of sports-related eye injuries in patients visiting the Emergency Department. METHODS A cross-sectional, multi-center, observational study. Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled. All data were prospectively collected between March and September 2010 using a questionnaire. Eye injuries that occurred during risky sports were examined by gender and age. Additionally, the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity. Continuous variables were compared using Student's t-test and categorical variables were compared using Chi-square test. RESULTS A total of 446 patients had sports-related eye injuries. Teenagers (10-19 years old) and young adults (20-29 years old) had the most eye injuries. Eye injuries accounted for 0.2% of Emergency Department patients. Baseball was the most common cause of sports-related eye injuries, followed by soccer and hiking. Protective gear was worn by 9.4% of all patients. Patients that were 30-39 years of age had the highest rate of protective gear use, followed by patients that were 40-49 years of age. The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking. CONCLUSION Although injuries were most common in patients below the age of 10 years, these patients had the lowest rate of protective eyewear use. Injuries in adults over 40 years of age most commonly occurred during hiking, but the rate of protective eyewear use was low. Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established. For older adults, eye protection should be encouraged, especially during hiking. PMID:27803871

    The purpose of the study was to analyze the relationships between sprint swimming performance, dry-land power, and kinematics in master swimmers. Twenty-two male master swimmers were separated in two groups based on their chronological age: (i) 30-39 years and; (ii) 40-49 years. Maximum dry-land power was determined through counter movement jump and 3 kg medicine ball throwing (Hmax and Tmax, respectively). Kinematic determinants of performance were measured during a maximal bout of 15, 25 and 50 m front crawl (T15, T25, T50). Stroke frequency (SF), stroke length (SL) and stroke index (SI) were calculated as kinematical aspects of the stroke. In the 30-39 group, SI25 was correlated to T25 (r = -0.76, p < 0.01, η2 = 0.96), the same was observed between SI50 and T50 (r = -0.83, p < 0.01, η2 = 0.96). Only SI50 was significantly correlated to T50 (r = 0.86, p < 0.01, η2 = 0.97) in the 40-49 years age cohort. In dryland power variables, Hmax and Tmax were only correlated in the younger master swimmers group (r = -0.87, p < 0.01, η2 = 0.97). There were no significant differences (p < 0.05) between younger (30-39 years) and older (40-49 years) swimmers groups in dry-land tests (Hmax 28.5 ± 5.9 vs. 26.5 ± 3.9 cm and Tmax 4.2 ± 1.0 vs. 4.2 ± 1.1 m). Our results suggest that swimming performance in younger master swimmers (30-39 years) seem more dependent on kinematic swimming variables than on strength parameters, which were most related to swimming performance in the older master swimmers (40-49 years).

    On 2012 May 20 and 29, two damaging earthquakes with magnitudes Mw 6.1 and 5.9, respectively, struck the Emilia-Romagna region in the sedimentary Po Plain, Northern Italy, causing 26 fatalities, significant damage to historical buildings and substantial impact to the economy of the region. The earthquake sequence included four more aftershocks with Mw ≥ 5.0, all at shallow depths (about 7-9 km), with similar WNW-ESE striking reverse mechanism. The timeline of the sequence suggests significant static stress interaction between the largest events. We perform here a detailed source inversion, first adopting a point source approximation and considering pure double couple and full moment tensor source models. We compare different extended source inversion approaches for the two largest events, and find that the rupture occurred in both cases along a subhorizontal plane, dipping towards SSW. Directivity is well detected for the May 20 main shock, indicating that the rupture propagated unilaterally towards SE. Based on the focal mechanism solution, we further estimate the co-seismic static stress change induced by the May 20 event. By using the rate-and-state model and a Poissonian earthquake occurrence, we infer that the second largest event of May 29 was induced with a probability in the range 0.2-0.4. This suggests that the segment of fault was already prone to rupture. Finally, we estimate peak ground accelerations for the two main events as occurred separately or simultaneously. For the scenario involving hypothetical rupture areas of both main events, we estimate Mw = 6.3 and an increase of ground acceleration by 50 per cent. The approach we propose may help to quantify rapidly which regions are invested by a significant increase of the hazard, bearing the potential for large aftershocks or even a second main shock.

    Clinical effects were investigated on cefadroxil powder for syrup (containing 100 mg of cefadroxil per 1 g) for acute bacterial infections (mostly scarlet fever) in the field of pediatrics, and the results were obtained as follows. Cefadroxil was applied in 100 cases of scarlet fever. Among 49 cases administered 30-39 mg/kg/day, the results were excellent in 34 cases and good in 15 cases, efficacy ratio being thus 100%. Among 38 cases administered 40-49 mg/kg/day, the results were excellent in 33 cases, and good in 5 cases, efficacy ratio being thus 100%. Out of 4 cases administered 20-29 mg/kg/day, the results were excellent in 3 cases and good in 1 case, while out of 9 cases administered 50-59 mg/kg/day, excellent in 4 cases and good in 5 cases. Among 78 cases of scarlet fever from which beta-hemolytic Streptococcus was proven from swab liquid of palatal tonsil, 67 cases received cefadroxil at a daily dose of 30-49 mg/kg, and the bacteria turned to negative the next day of administration in 72 cases, 2 days later in 6 cases. Cefadroxil was administered at a daily dose of 46 mg/kg for 7 days in 1 case of SSS syndrome of which Staphylococcus aureus was proven from skin lesion, and local bacteria turned to negative, as well as clinical effect was excellent. No pathogen was proven in 1 case of acute tonsillitis, maybe because ampicillin (ABPC) and cefazolin (CEZ) were administered before cefadroxil treatment, and yet a clinical efficacy was judged by administering cefadroxil at a daily dose of 46 mg/kg, though no clinical improvement was observed with the prior antibiotics. As to the side effects of cefadroxil in 102 cases, a slight vomiting was noticed in 6 cases, though the administration could be continued, and a slight rise of GOT or GPT was observed respectively in 3 cases and 1 case, all of which were recovered without abnormal clinical findings. Among the patients of scarlet fever, after beta-hemolytic Streptococcus became negative, reelimination or recurrence

    As concern regarding the toxic effects of bisphenol A (BPA) grows, BPA in many consumer products is gradually being replaced with compounds such as bisphenol S (BPS). Nevertheless, data on the occurrence of BPS in human specimens are limited. In this study, 315 urine samples, collected from the general populations in the United States, China, India, Japan, Korea, Kuwait, Malaysia, and Vietnam, were analyzed for the presence of total BPS (free plus conjugated) concentrations by high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). BPS was detected in 81% of the urine samples analyzed at concentrations ranging from below the limit of quantitation (LOQ; 0.02 ng/mL) to 21 ng/mL (geometric mean: 0.168 ng/mL). The urinary BPS concentration varied among countries, and the highest geometric mean concentration [1.18 ng/mLor 0.933 μg/g creatinine (Cre)] of BPS was found in urine samples from Japan, followed by the United States (0.299 ng/mL, 0.304 μg/g Cre), China (0.226 ng/mL, 0.223 μg/g Cre), Kuwait (0.172 ng/mL, 0.126 μg/g Cre), and Vietnam (0.160 ng/mL, 0.148 μg/g Cre). Median concentrations of BPS in urine samples from the Asian countries were 1 order of magnitude lower than the median concentrations reported earlier for BPA in the same set of samples, with the exception of samples from Japan. There were no significant differences in BPS concentrations between genders (male versus female), or among age groups (categorized as ≤ 19, 20-29, 30-39, 40-49, and ≥ 50 years), or races (Caucasian versus Asian). The daily intake (EDI) of BPS was estimated on the basis of urinary concentrations using a simple pharmacokinetic approach. The median EDI values of BPS in Japan, China, United States, Kuwait, Vietnam, Malaysia, India, and Korea were 1.67, 0.339, 0.316, 0.292, 0.217, 0.122, 0.084, and 0.023 μg/person, respectively. This is the first study to report the occurrence of BPS in human urine.

    We used Truven Health Marketscan claims database (2008-2011) to compare gastroenteritis rates during January-June among households whose child had received rotavirus vaccine with those whose child did not receive vaccine. Statistically significantly lower rates of hospitalization with a rotavirus gastroenteritis or unspecified-gastroenteritis discharge code occurred in vaccinated households among persons 20-29 years and females 20-29 years (2008/2009), and males 30-39 years (2009/2010). Lower emergency department gastroenteritis rates occurred in vaccinated households among females 20-29 years (2009/2010) and individuals 5-19 years (2010/2011). These data suggest rotavirus vaccination of infants provides indirect protection against moderate-to-severe rotavirus disease in young parents and older siblings.

    Air pollution with toxic chemical near oil-processing and petrochemical enterprises is significantly higher than in administrative district of the city. The studies proved that level and share of mortality with malignancies of trachea, bronchi and lungs is higher in industrial district, than that in the administrative one. The standardized parameters of mortality among females were increased in the industrial district, especially in 70s and 80s, i.e. in 10-20 years after launching the plants. The industrial district was characterized by higher mortality at young age. The mortality with the studied cancers at age of 20-29 and 30-39 prevailed in the industrial district.

    It was revealed that beta-endorphin modulation of lymphocyte proliferative activity in male donors was predominantly observed under younger age groups of 20-29 and 30-39 years, while with age it gradually decreased and disappeared as such in group of donors under 50-60 years. Meanwhile, females demonstrated prolonged modulating effect of peptide on the proliferation. In female group under 50-59 years the peptide was found to render marked promoting effect on the spontaneous proliferation in concentrations of 10(-7), 10(-8), and 10(-10) M that was induced by suboptimal PHA concentration of 10(-10) M, whereas women in the range of 30-39 years showed that beta-endorphin suppressed the PHA-induced proliferative response. Male donors in age group of 20-29 years demonstrated beta-endorphin-stimulated and in age group of 50-59 years beta-endorphin-suppressed uptake capacity of neutrophils. In female donors from all age groups the effect of beta-endorphin on neutrophil phagocyte activity was not observed. PMID:23885558

    The aims of this study were to assess whether Borderline Personality Disorder (BPD) features could be predicted by Big Five traits, impulsivity, identity orientation, and adult attachment patterns in a sample of 1,192 adult nonclinical participants, and to evaluate the consistency of these regression models across four age groups (<30 years, 30-39 years, 40-49 years, and >50 years, respectively). In the full sample, measures of neuroticism (N), impulsivity, and anxious insecure attachment were substantial predictors of BPD features (adjusted R(2) = .38, p < .001). Attachment scales were significant predictors of BPD features across all age groups, but different scales were relevant in different age groups. Our results suggest that in nonclinical populations, BPD may represent a complex constellation of personality traits and disturbed attachment patterns.

    Although a healthy lifestyle approach is intuitive for obese pregnant women, no guidelines currently exist to manage these women throughout pregnancy. Women who are medically prescreened for contraindications can engage in a walking program three to four times per week, starting at 25 min per session and adding 2 min per week until reaching 40 min, with sessions continuing until delivery. A target heart rate of 102-124 beats per minute should be promoted for women 20-29 years of age and a rate of 101-120 beats per minute for women 30-39 years of age. A pedometer step count of 10,000 steps per day is suggested as a goal, as this level of activity provides important health benefits. Combining healthy eating with a walking plan prevents excessive weight gain during pregnancy and promotes a healthy fetal environment.

    Advancing paternal and maternal age have both been associated with risk for autism spectrum disorders (ASD). However, the shape of the association remains unclear, and results on the joint associations is lacking. This study tests if advancing paternal and maternal ages are independently associated with ASD risk and estimates the functional form of the associations. In a population-based cohort study from five countries (Denmark, Israel, Norway, Sweden and Western Australia) comprising 5 766 794 children born 1985-2004 and followed up to the end of 2004-2009, the relative risk (RR) of ASD was estimated by using logistic regression and splines. Our analyses included 30 902 cases of ASD. Advancing paternal and maternal age were each associated with increased RR of ASD after adjusting for confounding and the other parent's age (mothers 40-49 years vs 20-29 years, RR=1.15 (95% confidence interval (CI): 1.06-1.24), P-value<0.001; fathers⩾50 years vs 20-29 years, RR=1.66 (95% CI: 1.49-1.85), P-value<0.001). Younger maternal age was also associated with increased risk for ASD (mothers <20 years vs 20-29 years, RR=1.18 (95% CI: 1.08-1.29), P-value<0.001). There was a joint effect of maternal and paternal age with increasing risk of ASD for couples with increasing differences in parental ages. We did not find any support for a modifying effect by the sex of the offspring. In conclusion, as shown in multiple geographic regions, increases in ASD was not only limited to advancing paternal or maternal age alone but also to differences parental age including younger or older similarly aged parents as well as disparately aged parents.

    OBJECTIVE: To enumerate drowning fatalities in Alaska in order to identify risk factors and areas for intervention. METHODS: Information from death certificates, state troopers' reports, and medical examiner reports were abstracted and analyzed. Rates were calculated using 1990 census figures as denominator data. RESULTS: There were 542 drowning fatalities in Alaska for the years 1988 to 1992. The 20-29 age group had the highest frequency and rate of drownings. The incidence rate for the state was 20 drownings per 100,000 population per year, almost 10 times higher than the overall U.S. rate of 2.11 per 100,000 per year. Incidence rates were highest among adolescent males (10-19), young adult males (20-29). Alaska Natives, and rural residents. Alaska Native males, ages 30-39 averaged 159 drownings per 100,000 per year, the highest drowning rates in the state. CONCLUSIONS: Drowning is a major public health concern in Alaska. People who fish commercially and young Native males are groups at high risk for drowning. Intervention efforts should be concentrated on these two populations. PMID:8955701

    The aim of this study was to evaluate diphtheria immunity in a sample of the Turkish population having high childhood immunization coverage, including a booster dose of diphtheria toxoid at 12-15 years of age. A total of 599 persons aged 1-70 years were selected with cluster sampling. The information on socio-demographic characteristics, vaccination status and diphtheria history was gathered for each participant. Diphtheria antitoxin levels were measured qualitatively by using micro-enzyme immune assay. Of studied population, 72.3% had fully protective antitoxin levels (≥ 0.1 IU/ml). The rate of protection was 92.5% in the children aged 0-2 years, 93.2% in the primary school children aged 7-9 years, and 86.0% in the adolescents aged 15-19 years. After 20 years of age, diphtheria protection rates showed a significant age-related decrease, reaching minimum in the 30-39 age group, in which 47.3% of these subjects had fully protective antitoxin levels. The diphtheria antitoxin geometric mean titer (GMT) was highest in the 0-2 year age group (1.18 IU/ml). In the adolescents aged 15-19 years, diphtheria antitoxin GMT was 0.71 IU/ml. Then, geometric mean titer decreased with increasing age, and reached the minimum level in the 40-59 years age group (0.18 IU/ml). The protection rate among females was significantly lower than males (67.1% vs. 80.9%). The difference was apparent in the 20-29 and the 30-39 years age group: 80% of the males and 46.2% of the females in the 20-29 years age group, and 60% of males and 44.1% of females in the 30-39 years age group were fully protected against diphtheria (p<0.0001). These results suggest that in Izmir, Turkey, full serological protection against diphtheria is only detectable in <50% of the young adult population, even though childhood immunization coverage is relatively high. Potentially, there is still risk of diphtheria outbreaks among the adults in our country. Therefore, a revaccination of adults with reduced doses of

    Background Retention in care is important for all HIV-infected persons and is strongly associated with initiation of antiretroviral therapy and viral suppression. However, it is unclear how retention in care and age interact to effect viral suppression. We evaluated whether the association between retention and viral suppression differed by age at entry into care. Methods Cross-sectional analysis (2006-2010) involving 17,044 HIV-infected adults in 14 clinical cohorts across the U.S. and Canada. Patients contributed one year of data during their first full calendar year of clinical observation. Poisson regression examined associations between retention measures [U.S. National HIV/AIDS Strategy (NHAS), U.S. Department of Health and Human Services (DHHS), 6-month gap, and 3-month visit constancy] and viral suppression (HIV RNA ≤200 copies/mL) by age group: 18-29, 30-39, 40–49, 50–59, and ≥60 years old. Results Overall, 89% of patients were retained in care using the NHAS measure, 74% with the DHHS indicator, 85% did not have a 6-month gap, and 62% had visits in 3-4 quarters of the year; 54% achieved viral suppression. For each retention measure, the association with viral suppression was significant for only the younger age groups (18-29 and 30-39 years): 18-29 [adjusted prevalence ratio (APR)=1.33, 95% confidence interval (CI)=1.03-1.70]; 30-39 (APR=1.23, CI=1.01-1.49); 40-49 (APR=1.06, CI=0.90-1.22); 50-59 (APR=0.92, CI=0.75-1.13); ≥60 years (APR=0.99, CI=0.63-1.56) using the NHAS measure as a representative example. Conclusions These results have important implications for improving viral control among younger adults, emphasizing the crucial role retention in care plays in supporting viral suppression in this population.

    Schizophrenia is a major cause of psychiatric disability in China. In the present study, we estimated total and age-specific prevalence of both schizophrenia disability and associated mortality among Chinese women and men. We further examined whether sex differences in prevalence were attributable to mortality differences between men and women. Data from the Second China National Sample Survey on Disability (2006) and the 2007-2010 follow-up studies were utilized. Possibly psychiatrically disabled individuals were administered the World Health Organization Disability Assessment Schedule, Version II and the ICD-10 Symptom Checklist for Mental Disorders by trained clinical psychiatrists. In total, 0.37% of men and 0.44% of women were living with schizophrenia disability in China. We did not find statistically significant differences in the 4-year cumulative mortality between men and women. Overall standardized mortality ratios for the age groups of 18-29, 30-39, 40-49, 50-59, 60-69, and 70+ years were 120.89, 29.56, 15.06, 9.16, 10.57, and 4.95, respectively. In conclusion, mortality differences between men and women were unlikely to be a major contributor to sex differences in prevalence. Premature death among younger individuals experiencing schizophrenia disability warrants urgent attention. PMID:25113924

    The aim of this study is to describe trends in the percentage of samples with undetectable HIV viral load in Spain after the implementation of HAART. A descriptive observational study of HIV-VL measurements carried out in the microbiology department of the Hospital Clínico Universitario de Valladolid (HCUV) was conducted over a 9-year period (1996-2004). Regarding the trend over the study period, the 30-39 years age group accounted for most of the samples, although the percentage decreased from 65.5% to 59.6% over the study period. In contrast, the 40-49 years group increased from 9.1% to 14.5%. The preponderance of men, with percentages above 70%, was observed during the whole period. Although the purpose of this treatment is to maintain undetectable viral loads, since 1999 more than 60% of nonfirst samples had detectable levels. Based on the results of the VL trend among HIV/AIDS patients observed in this study, a large number of patients maintain elevated detectable VL years after HAART was implemented. Although different factors may be the cause of this and should be delimited in future studies, the phenomenon observed demonstrates the usefulness of monitoring VL and analyzing its time trend to gain further knowledge about the therapeutic results and care of HIV patients as a whole, also serving as the basis for corrective measures.

    In order to clarify poor sleep habits and prevalence in sleep problems (disturbances) of healthy male white-collar workers and the relationship of these to age and job type, a total of 1,161 Japanese employees of an electric equipment manufacturing company (aged 23 to 59, mean 37 years) were surveyed by means of a mailed questionnaire. The workers were asked about eleven sleep habits. They were also divided into four groups according to age and job type: 23-29 (n = 226), 30-39 (n = 597), 40-49 (n = 225) and 50-59 (n = 113); managerial (n = 209), professional (n = 336), technical (n = 475) and clerical (n = 134). In this study, the sleep problems were defined as who had at least one of the following four poor sleep habits: 1) taking more than 30 minutes to fall asleep, 2) awakening during sleep (ADS) almost every day, 3) early morning awakening (EMA) almost every day, and 4) excessive daytime sleepiness (EDS) at work almost every day. Analyses showed that sleep problems were present in 26.0% of workers; the problems were most serious among workers aged 50 years and more (36.0%) which may be due to a significant increase in the prevalence rate of EMA. The results revealed that sleep problems are common in male white-collar daytime workers. The findings also suggest a need for increased attention to sleep problems in older workers and younger ones with EDS at work.

    Drivers' reactions to a semi-autonomous technology for assisted parallel parking system were evaluated in a field experiment. A sample of 42 drivers balanced by gender and across three age groups (20-29, 40-49, 60-69) were given a comprehensive briefing, saw the technology demonstrated, practiced parallel parking 3 times each with and without the assistive technology, and then were assessed on an additional 3 parking events each with and without the technology. Anticipatory stress, as measured by heart rate, was significantly lower when drivers approached a parking space knowing that they would be using the assistive technology as opposed to manually parking. Self-reported stress levels following assisted parks were also lower. Thus, both subjective and objective data support the position that the assistive technology reduced stress levels in drivers who were given detailed training. It was observed that drivers decreased their use of turn signals when using the semi-autonomous technology, raising a caution concerning unintended lapses in safe driving behaviors that may occur when assistive technologies are used.

    We present the results of the first epidemiological study on lipidic levels among a healthy population from Extremadura. The study included 1.128 subjects, 520 males and 608 females, distributed by age and sex. Average total cholesterol levels were 228 +/- 40 mg/dl among middle-age and 215.6 +/- 43 mg/dl among women. We observed a significant reduction of these figures in ages above 60. In addition, we observed significant differences in HDL-Ch levels between men and women from all ages, with higher values among women and we only observed significant differences regarding total cholesterol levels between men and women in the 20-29 and 40-49 age-groups. Total cholesterol levels were higher than 220 mg/dl in more than half the studied population between 40 and 60 years of age and higher than 250 mg/dl in 20% of the subjects in such age groups. These data suggest the need for dietary changes in near 70% of the population if cholesterol levels are to approach the recommendations of the Sociedad Española de Arteriosclerosis.

    We report the epidemiology and laboratory diagnostic results of rubella cases from 2011 to 2013 in Hokkaido district, Japan. A total of 150 cases were officially reported as rubella; 102 (68%) involved males and 48 (32%) involved females. The highest proportion of cases were notified in 40-49-year-old age group among males and the 20-29-years-old age group among females. Forty-six cases (25 males and 21 females) had not been vaccinated, and 17 had been vaccinated, whereas 87 had the unknown vaccination status. Eighty-three cases (55.3%) showed the 3 typical principal rubella symptoms (fever, rash, and lymphadenopathy). Seven, 11, 92, and 40 cases were identified in the northern, eastern, central, and southern areas of Hokkaido district, respectively. In the central and southern areas of Hokkaido district, endemic rubella transmissions were indicated by both the epidemiological survey and molecular analyses. However, these outbreaks terminated spontaneously and did not expand to other areas of Hokkaido district. Fortunately, no congenital rubella syndrome (CRS) cases were reported during this observation period. However, to control virus transmission, prevent CRS, and maintain the routine vaccination program, the immediate introduction of an immunization strategy is required for susceptible individuals, particularly young adults.

    This research is based on epidemiological records of toxicological occurrences in individual records of investigation into pesticide poisoning at the Maringá Intoxication Control Center at the Regional University Hospital of Maringá. The intoxications in patients poisoned from 2002 to 2011, in towns that comprise the Central Northern Paraná Geographic Mesoregion where Maringá is located, were taken into consideration in this study. As a result, it was established that approximately 67.12% of those poisoned were males, the age groups most affected are 20-29 years old and 30-39 years old. Suicide attempts appear as the main motivation for hospitalization (possibly disguising the chronic intoxication), and mainly insecticides and herbicides are involved in the poisonings, with 62.60% and 26%, respectively. Lastly, the urgent need for public health policies in to reduce this statistic immediately is self-evident, as these poisonings are the ones recorded, as those resulting from food poisoning are not being computed.

    The present study was performed to determine the seroprevalence of IgG measles antibodies in Dongguan residents (irrespective of vaccination status), to analyze the changes in age-related serological susceptibility patterns. A total of 1960 residents aged 0-60 years and 315 mother-infant pairs were studied. Serum IgG antibodies against measles virus were measured by ELISA. The overall seroprevalence was 93.4% in the general population in Dongguan, China. In subgroups aged 1-29 years who were likely vaccinated, there was a declining trend of seropositivity with age from 98.6% at 1-4 years to 85.7% at 20-29 years (P<0.0001). Seroprevalence were near or>95% in the older population (30-39 years and ≥ 40 years) who had not been immunized against measles. Age and sex were independent factors associated with seropositivity. Seroprevalence in pregnant women and their newborns was 87.0% and 84.1%, respectively. Our results suggest that the waning vaccine-induced immunity may be the main cause of increased serological susceptibility in young adults and young infants. An additional vaccination strategy that targets young adults is important for elimination of measles. PMID:24448194

The HIV infected individuals predominated in the age group ranging from 20 to 40 years (73.4%) and 75% were male. The was no difference in the ratio of male and female patients regarding asymptomatic HIV infection or AIDS. The cases of HIV without AIDS concentrated in the age group ranging from 20-29 years while AIDS predominated in the age group ranging from 30-39 years. Only 0.8% were hemophilic, 3.5% injected drugs and 4.8% had hemotransfusions in the last 5 years. Regarding sexual behavior, 33% were heterosexuals, 11% bisexuals, 23% homosexuals and 33% did not disclose their sexual behavior. The presence of syphilis was the most frequent combination found (8.8%), followed by herpes (5.8%) and genital candidiasis (4.3%). Our results suggest an association between genital candidiasis and AIDS, although this was not demonstrated for the other STDs studied.

    Emotions play an important role in human behavior. Negative emotions resulting from medical disputes are problems for medical personnel to solve but also have a significant impact on a hospital's reputation and people's trust in the hospital. One medical dispute case was chosen from an Internet news source to assess the correlation between people's negative emotions and negative online word-of-mouth. Convenience sampling was used in school faculties and university students who had shared their medical treatment experiences online were the research participants. A total of 221 Taiwanese participants volunteered (158 women, 63 men; ages: 26.7% under 19, 22.6% 20-29, 30.8% 30-39,19.9% over 40). Four negative emotions were measured using rating scales: uncertainty, anger, disappointment, and sadness. Four negative online word-of-mouth measures were: venting, advice search, helping receiver, and revenge. A modeled relationship was assessed by partial least square method (PLS). Then, people's positive emotions were further analyzed to assess changes after spreading negative word-of-mouth. The results showed that uncertainty had a positive effect on venting and advice search. People who felt anger or regret spread word-of-mouth in order to help the receiver. Disappointment may trigger the revenge behavior of negative word-of-mouth. Negative emotions could be relieved after engaging in the behavior of helping the receiver. PMID:26226491

    Background Cases of acute hepatitis C virus (HCV) have been rising across the United States, and southwest Ohio is no exception. Objectives To describe the rise in cases of HCV in our region, the Ohio Disease Reporting System was reviewed for all cases of positive HCV testing from 2010 through August 2015. Methods 29,018 cases were reviewed, with 18,678 (64.4%) cases included in the final analysis. The incidence of newly reported cases of HCV was calculated, and demographic data were reviewed to describe the populations at greatest risk. Results All counties reviewed demonstrated a rise in the incidence of new cases of positive HCV testing. All age groups demonstrated an increased incidence of positive HCV tests, with the most substantial rise occurring among individuals aged 20 - 29 and 30 - 39. There was a slight male predominance (53%), and the majority of individuals were white (82%). Conclusions Southwest Ohio is experiencing a rise in positive HCV testing among young adults. Further research is required to determine the burden of disease, define the primary risk factors associated with disease acquisition, and develop appropriate public health interventions.

    After an extensive vaccination policy, Japanese encephalitis (JE) was nearly eliminated since the mid-1980s in South Korea. Vaccination in children shifted the affected age of JE patients from children to adults. However, an abrupt increase in JE cases occurred in 2010, and this trend has continued. The present study aimed to investigate the prevalence of neutralizing antibodies to the JE virus (JEV) among high-risk age groups (≥40 years) in South Korea. A plaque reduction neutralization test was conducted to evaluate the prevalence of neutralizing antibodies to JEV in 945 subjects within four age groups (30-39, 40-49, 50-59, and 60-69 years) in 10 provinces. Of the 945 enrolled subjects, 927 (98.1%) exhibited antibodies against JEV. No significant differences were found in the prevalence of neutralizing antibodies according to sex, age, or occupation. However, there were significant differences in the plaque reduction rate according to age and occupation; oldest age group had a higher reduction rate, and subjects who were employed in agriculture or forestry also had a higher value than the other occupations. We also found that three provinces (Gangwon, Jeonnam, and Gyeongnam) had a relatively lower plaque reduction rate than the other locations. In addition, enzyme-linked immunosorbent assays were conducted to determine recent viral infections and 12 (1.3%) subjects were found to have been recently infected by the virus [corrected]. In conclusion, the present study clearly indicated that the prevalence of neutralizing antibodies has been maintained at very high levels among adult age groups owing to vaccination or natural infections, or both. In the future, serosurveillance should be conducted periodically using more representative samples to better understand the population-level immunity to JE in South Korea.

    Fibromyalgia is associated with physical disabilities in daily activities. Moreover, patients with fibromyalgia present similar levels of functional capacity and physical condition than elderly people. The aim of this study was to analyse the evolution of strength and muscle mass in women with fibromyalgia along ageing. A total sample of 492 fibromyalgia patients and 279 healthy control women were included in the study. Participants in each group were further divided into four age subgroups: subgroup 1: 30-39 years old, subgroup 2: 40-49 years old, subgroup 3: 50-59 years old and subgroup 4: 60-69 years old. Standardized field-based fitness tests were used to assess muscle strength (30-s chair stand, handgrip strength and arm curl tests). Fibromyalgia patients did not show impairment on muscle mass along ageing, without values of skeletal muscle mass index below 6.76 kg/m(2) in any group. However, in all variables of muscle strength, the fibromyalgia group showed less strength than the healthy group (p < 0.05) for all age groups. As expected, handgrip strength test showed differences along ageing only in the fibromyalgia group (p < 0.001). Age was inversely associated with skeletal muscle mass (r = -0.155, p < 0.01) and handgrip strength (r = -0.230, p < 0.001) in the FM group. Women with fibromyalgia showed a reduction in muscle strength along ageing process, with significantly lower scores than healthy women for each age group, representing a risk of dynapenia.

    The aims of this study are to determine the frequency of patients presenting with Meniere's Disease(MD) in an Indian setting, using the American Academy of Otolaryngology-Head and Neck Surgery (AAO) diagnostic criteria, and to describe the clinical and audio vestibular profiles of these patients. The study was based on prospective case series design in the settings of a tertiary referral hospital. The study included all consecutive patients aged between 5 and 75 years presenting with the history of hearing loss, vertigo, tinnitus and or aural fullness as participants, satisfying inclusion and exclusion criteria for MD (AAO 1995) recruited over a 12 month period. Main outcome measures comprised the evaluation of epidemiological profile, clinical features, and results of audio vestibular investigations like Pure Tone Audiometry with and without glycerol, Impedance Audiometry, Electrocochleography (ECohG), Distortion Product Otoacoustic Emission and Electronystagmography (ENG). The results of the study are as follows: The frequency of MD was 15.6%, being commoner in males than females (2.6:1) and occurring more in the age group 40-49  years among males and 30-39 years among females. High frequency tinnitus was commoner than low frequency tinnitus. Extra tympanic ECohG had a positive predictive value of 76% for endolymphatic hydrops. ENG was useful for demonstrating canal paresis pattern of nystagmus in 61%. Indian patients with MD commonly present to tertiary care at the functional level scale of 3. The results of this study revealed that the frequency of MD is not as low in the Indian ENT setting as earlier believed. There is a high chance of missing cases in the routine ENT outpatient clinic setting unless a structured proforma incorporating the AAO 1995 diagnostic criteria is used. PMID:24294577

    Objective: To verify whether 30 minutes of rest between two incremental shuttle walking tests (ISWT) are enough for cardiovascular variables and perceived exertion to return to baseline values in healthy subjects in a broad age range. Method: The maximal exercise capacity of 334 apparently healthy subjects (age ≥18) was evaluated using the ISWT. The test was performed twice with 30 minutes of rest in between. Heart rate (HR), arterial blood pressure (ABP), dyspnea, and leg fatigue were evaluated before and after each test. Subjects were allocated to 6 groups according to their age: G1: 18-29 years; G2: 30-39 years; G3: 40-49 years; G4: 50-59 years; G5: 60-69 years and G6: ≥70 years. Results: All groups had a good performance in the ISWT (median >90% of the predicted distance). The initial HR (HRi) of the second ISWT was higher than the first ISWT in the total sample (p<0.0001), as well as in all groups (p<0.0001). No difference was observed in the behavior of ABP (systolic and diastolic) and dyspnea between the two tests, but this difference occurred for leg fatigue (greater before the second ISWT) in G1 (p<0.05). Most subjects (58%) performed better in the second test. Conclusion: 30 minutes of rest between two ISWTs are not enough for all cardiovascular variables and perceived exertion to return to baseline values. However, this period appears to be sufficient for blood pressure and performance to recover in most subjects. PMID:25789556

Also, 179 M. californicus nests were collected monthly with observations to identify the environment of fleas. The ratio of the mean number of fleas per nest to the mean number collected on voles was 4.7:1 for Malaraeus telchinus (Rothschild, 1905), 13:1 for Hystrichopsylla occidentalis linsdalei Holland, 1957,9:1 for Atyphloceras multidentatus multidentatus (C. Fox, 1909), and 76:1 for Catallagia wymani (C. Fox, 1909). The proportion of each flea species per nest to those per host was not closely associated seasonally or spatially. The average nest contained 37.5% moisture content in relation to its total weight and ranged between 3 and 92%. No relationship was observed between relative humidity of air within nests and flea number, but a significant relationship existed between the moisture of nesting materials and flea number. Malaraeus telchinus and A. m. multidentatus were collected in greatest numbers from nests having 30-39% moisture content by weight, and H. o. linsdalei and C. wymani were most numerous in nests that had 40-49% moisture content. Catallagia wymani had the greatest tolerance for high moisture and was severely affected by lack of moisture and nearly absent in drier nests. No ectoparasites were collected from nests that had <12% moisture content, and nests with >50% moisture content had few fleas. A static concept of nest fleas and host fleas as suggested by averages and often used in literature is questionable. In seasonal comparison of populations of fleas on hosts and in nests, M. telchinus and H. o. linsdalei reversed so that more of the flea population was on the host than in the nest for a short time during fall.

    Seroprevalence of human herpesvirus 6 (HHV-6) and 7 (HHV-7) was estimated in the Thai population using indirect immunofluorescence assay to determine serum antibodies to HHV-6 and HHV-7. A total of 333 serum samples obtained from umbilical cord blood and venous blood of healthy persons at Siriraj Hospital and Krabi Hospital during 1990-1993 were investigated. Of 73 infants aged 0-1 month, 73% and 78% were found tob e positive for HHV-6 and HHV-7 antibodies, respectively. Antibody to HHV-6 was detected in age groups 2-3 months (38%), 4-5 months (14%), 6 months (44%), 7-11 months (66%), 1-2 year (84%), 3-4 years (82%), 5-9 years (83%), 10-19 years (83%), 20-29 years (80%), 30-39 years (67%), and over 40 years (58%), respectively. This positive rates of HHV-7 antibody in age groups 2-3 months, 4-5 months, 6 months, 7-11 months, 1-2 years, 3-4 years, 5-9 years, 10-19 years, 21-29 years, 30-39 years, and over 40 years were 50%, 21%, 10%, 37%, 47%, 82%, 75%, 72%, 72%, 67%, and 67%, respectively. At 6 months of age as the starting time of infections, 34% (14/41) and 9% (3/41) of infants had presumed primary infections of HHV-6 and HHV-7, respectively. In the follow-up study, 53% (20/38) of children were infected with HHV-6 prior to HHV-7 and only 5% vice versa. Eighty-four percent of children had acquired antibody to HHV-6 by 1-2 years old while 82% of children had acquired antibody to HHV-7 by 3-4 years old. These results suggest that HHV-6 and HHV-7 are prevalent viruses in the Thai population. The infections of both viruses begin at 6 months of age. However, infection of HHV-7 in most children begins later. The data also provided evidence that antigenic distinction between HHV-6 and HHV-7 existed with a limited cross-reactivity in an antibody test. The antibody responses to HHV-6 and HHV-7 occurred independently.

    Objectives. To examine fatal and non-fatal incidents involving tourists in Hawaii Volcanoes National Park. Methods. Official press releases from the public relations office at Hawaii Volcanoes National Park were examined for reports of fatal and non-fatal incidents involving tourists. Results. Between 1992 and 2002 there were 65 press releases reporting 40 fatalities, 45 serious injuries, 53 minor injuries, and 25 no injury events. Severity information was unavailable for four additional tourists. Aircraft and backcountry incidents each accounted for 30% of all incidents followed by road incidents (22%) and frontcountry incidents (17%). Aircraft incidents reported 17 fatalities, backcountry incidents accounted for 10 fatalities, frontcountry incidents reported seven fatalities, and road incidents totaled six fatalities. One fatality was classified as a suicide. Backcountry (23) and road (10) incidents had the highest number of serious incidents. Male tourists (62) were more frequently involved in incidents than female tourists (41) and tourists aged 20-29 years and 40-49 years accounted for the highest number of fatalities and total incidents. Conclusions. Helicopter tours, hiking in areas with active lava flows, falls into steam vents and earthcracks, and driving unfamiliar rental cars in unfamiliar locations are the major activities resulting in death and serious injury. Additional factors such as tourists ignoring warning signs, wandering off-trail or hiking at night, tourists misinformed by guidebooks and other tourists, and tourists with pre-existing heart and asthma conditions are contributing causes in many incidents. The findings of this study provide information that allows prospective tourists, tourism managers, and travel health providers make informed decisions that promote safe tourism and can aid future efforts in developing preventative strategies at tourist destinations with similar environments and activities.

    We investigated association of lean body mass with bone mass (BM) and bone mineral density (BMD) according to gender and menopausal status in the general Korean population. Participants included 4,299 males and 5,226 females who were 20 years of age or older from the fourth and fifth Korea National Health and Nutritional Examination Surveys (2009-2010). Dual-energy X-ray absorptiometry was used for measurement of BMD and body composition. BMD was measured in the femur and lumbar spine. Appendicular skeletal muscle mass (ASM) was defined as the sum of the lean soft tissue masses for the arms and legs. Analysis was performed after categorizing participants into four groups (males <50 years, males ≥ 50 years, premenopausal females, and postmenopausal females). In males, the highest ASM was observed in the 20-29-year group and then showed a gradual decrease as age increased, and BM and BMD showed similar patterns of change, while in females, ASM, BMD, and BM reached the peak level in the 40-49-year group and then decreased. In multiple regression analysis, after adjusting for confounding factors, the results showed an independent association of ASM with an increase in BM and BMD (P < 0.05). After adjusting for confounding factors, total fat mass showed a significant association with BM (P < 0.05). These aforementioned relationships were commonly observed on both femur and lumbar spine in every group. Lean body mass showed an independent association with increased BM and BMD, regardless of gender, age in men, and menopausal status in women. PMID:24415174

    Because of low rates of colorectal cancer screening among African Americans, it may be beneficial to begin educating persons about this disease before age 50. Using the Patient/Provider/System Theoretical Model for cancer screening, this study compared knowledge of colorectal cancer, sources of information, and awareness of programs among participants of age 20-29, 30-49, and 50-75 years. The majority (n = 354) were women and African American (mean age = 37 years, mean education = 12th grade). Younger participants tended to know less about the disease, but there were few differences in knowledge between the two older groups. Persons in the 40-49-year age group were more likely to be familiar with the role diet plays in the risk of colorectal cancer. Participants associated the need for screening with the presence of symptoms. Television and radio were listed as the most frequent source of information about cancer. The Internet was the least used. The majority were not familiar with selected national programs and services focused on increasing awareness of cancer. Findings suggest that colorectal cancer-related information should be targeted toward this population before age 50, using multiple sources such as TV/radio, providers, magazines, and cancer-related organizations. An estimated 104,950 colon and 40,340 rectal cancer cases will be diagnosed in 2005 with an estimated 56,290 deaths from the disease (American Cancer Society [ACS], 2005). Despite a stabilization of colorectal cancer (CRC) incidence rates since the 1980s, African American males and females have higher incidence and mortality rates associated with this disease compared to Whites. The 5-year survival rate for CRC among African Americans improved to 54% during the years 1995-2000, but lagged well behind the 64% survival rate for Whites during the same time period. Screening and early detection of CRC followed by effective treatment is crucial to reducing these mortality rates.

    Laboratory experiments and weekly trammel net surveys in the Navesink River, New Jersey (USA) were used to examine the predator-prey interaction between age-1+ summer flounder (Paralichthys dentatus) and age-0 winter flounder (Pseudopleuronectes americanus). Winter flounder (24-67 mm TL) were the dominant piscine prey of summer flounder (n=95, 252-648 mm TL) collected in trammel nets. We observed a temporal shift in summer flounder diets from sand shrimp (Crangon septemspinosa) and winter flounder, dominant during June and early July, to blue crabs (Callinectes sapidus) and other fishes (primarily Atlantic silversides, Menidia menidia and Atlantic menhaden, Brevortia tyrannus) later in the summer. Variations in prey selection appeared to be related to changes in the spatial distribution of predators and spatio-temporal variation in prey availability. In laboratory experiments, summer flounder (271-345 mm total length, TL) preferred demersal winter flounder to a pelagic fish (Atlantic silversides) and a benthic invertebrate (sand shrimp) prey, and the vulnerability of winter flounder increased with increasing prey body size from 20 to 90 mm TL. Experiments testing habitat effects showed that mortality of winter flounder in three different size classes (20-29, 40-49, 60-69 mm TL) was not influenced by sediment grain sizes permitting differential burial of the prey. However, vegetation enhanced survival, with fish suffering lower mortality in eelgrass (Zostera marina, 15+/-0.04%) than in sea lettuce (Ulva lactuca, 38+/-0.04%) or bare sand (70+/-0.07%) when the macrophytes were planted to produce similar leaf surface areas (5000 cm(2) m(-2)). Prey vulnerability appeared to be related to the role of vision in the predator's attack strategy and prey activity levels. PMID:10958899

    The purpose of this study was to investigate the latest trends and demographics of surgical treatment of posterior cruciate ligament (PCL) insufficiency in the United States. Patients who underwent surgical treatment of PCL insufficiency from 2007 to 2011 were identified by searching the International Classification of Diseases, Ninth Revision, Clinical Modification codes and Current Procedural Terminology codes in the PearlDiver Patient Records Database (PearlDiver Technologies, Warsaw, Indiana), a publicly available national database of insurance records. The chronicity of injury, year of procedure, age, sex, region of the United States the surgery was performed, and other concomitant meniscus and ligamentous operations were elicited for each patient. In total, 701 cases of surgical PCL procedures (222 isolated and 479 combined) were identified. More PCL surgeries were completed for acute injuries (74%) than for chronic injuries (26%). Among associated procedures, meniscectomies and meniscus repairs were performed for 293 (41%) and 51 (7%) patients, respectively. Meniscectomies were completed in 77 (35%) isolated reconstructions vs 216 (45%) combined reconstructions (P=.01; odds ratio, 0.65). Of the combined PCL surgeries, anterior cruciate ligament (ACL)/PCL was the most common (62%), followed by ACL/PCL/collateral ligament repair (11%) and PCL/other ligamentous reconstruction (9%). No specific trends were observed in the yearly number of PCL procedures performed. The peak number of isolated PCL surgeries was observed in a younger age group (20-29 years) than that of combined PCL surgeries (30-39 years) (P<.01). Surgical treatment for PCL insufficiency remains reserved for acute multiligamentous knee injuries, with ACL/PCL operations being the most common combined procedure.

    The first case of HIV/AIDS in Morocco was notified in 1986. The Moroccan Ministry of Health has set up a system of management of HIV/AIDS cases and surveillance of the epidemic. Between 1991 and 1999, we studied 12,981 sera from patients in different Moroccan regions, who attended with high risk and/or symptoms of HIV/AIDS. The overall prevalence of positive HIV serology was 5.04% (4.67-5.44%). This rate was higher compared to blood donors which is 0.02%. From 1993 to 1998, the prevalence was around 4-5% (2.73-6.26%) then increased to 8.06% (6.89-9.36%) in 1999. Retrospective analysis of available epidemiological data have shown that the highest rate was observed in the South of Morocco with 12.23% (11.10-13.44%). Of the HIV positive cases, 72.22% of seropositives were infected heterosexually, 11.11% by intravenous drugs use, 7.41% by homosexuality, 4.63% by bisexuality and 4.63% and 0.62% by vertical transmission. The median age of infected persons was 33.3 years. Among documented HIV-positive individuals, 53.74% were aged 30-39 years, 21.43% were 20-29 years and 17.69% were 40 years or more. In this study, among HIV-positive patients 42.17% have loss of weight with fever and diarrhoea represent and 35.54% have loss of weight with fever, diarrhoea and opportunistic infections. The present work shows that the HIV infection increased significantly in 1999. Effective measures to control this trend should be implemented soon before the situation worsens.

    The hepatitis A virus (HAV) has been the leading cause of viral hepatitis in Korea since the 2000s. We aimed to describe the current status and regional differences in hepatitis A incidence. We studied the total number of hepatitis A cases reported to the Korea Centers for Disease Control and Prevention through the National Infectious Diseases Surveillance System between 2011 and 2013. Additionally, National Health Insurance Review and Assessment Service data and national population data from Statistics Korea were used. In total, 7,585 hepatitis A cases were reported; 5,521 (10.9 cases per 100,000 populations), 1,197 (2.3 cases per 100,000 populations), and 867 (1.7 cases per 100,000 populations) in 2011, 2012, and 2013, respectively. Fifty-eight patients were infected outside of the country and 7,527 patients represented autochthonous HAV infection cases. Autochthonous HAV infection occurred more frequently among men than women (4,619 cases, 6.1 cases per 100,000 population vs. 2,908 cases, 3.9 cases per 100,000 population). The incidence rate was higher in the 20-29 yr-old group (2,309 cases, 11.6 cases per 100,000 populations) and 30-39 yr-old group (3,306 cases, 13.6 cases per 100,000 populations). The majority of cases were reported from March to June (53.6%, 4,038/7,527). Geographic analyses revealed a consistently high relative risk (RR) of HAV infection in mid-western regions (2011, RR, 1.25, P=0.019; 2012, RR, 2.53, P<0.001; 2013, RR, 1.86, P<0.001). In summary, we report that hepatitis A incidence has been decreasing gradually from 2011 to 2013 and that some regions show the highest prevalence rates of HAV infection in Korea.

    The body size of adult Cook Islanders on Rarotonga for the years 1952, 1966 and 1996 has been increasing. The rate of increase in stature of women aged 20-39 years was 0.5cm per decade across the period 1952-1966, and 0.8cm per decade for the period 1966-1996. The rate of increase of weight in the 20-29 years age group was 0.6kg per decade in period 1, and 7.3kg per decade in period 2. In the age group 30-39 years, the rates were 3.2kg per decade and 5.1kg per decade respectively. Changing food availability for the period 1961-2000 is used to compare estimates of dietary energy availability with estimates of physiological energy requirements. There has been reduced availability of traditional staples, a likely reduction in consumption of fish, increased consumption of meat, and a decline in the availability of dietary fats and oils. Daily per capita energy intakes in 1952 and 1966 greatly exceed an hypothetical physiological maximum value for energy expenditure, suggesting a large positive energy balance in 1952 and an even greater one in 1966, both predisposing to weight gain. Although daily per capita energy availability in 1996 is similar to the hypothetical physiological maximum value for energy expenditure, it exceeds the measured level of energy expenditure at that time. It is speculated that excessive energy intake relative to requirement is more likely to predispose to positive energy balance and weight gain than decline in energy expenditure, although to a lower extent than in 1966 and 1952.

    For 1950-74, 360 cases of malignant breast tumors were identified among the 63,000 females of the Radiation Effects Research Foundation's (Hiroshima and Nagasaki) Extended Life-Span Study sample of survivors of the 1945 atomic bombings of Hiroshima and Nagasaki; 288 of these females were residing in one of these two cities at the time of bombing (ATB). Two-thirds of all cases were classified as breast cancers on the basis of microscopic review of slides, and 108 cases received an estimated breast tissue dose of at least 10 rads. The number of cases of radiogenic breast cancer could be well estimated by a linear function of radiation dose for tissue doses below 200 rads. Excess risk estimates, based on this function, for women 10-19, 20-29, 30-39, and 50 years old or older ATB were 7.3, 4.2, 2.6, and 4.7 cases per million women per year per rad, respectively. Women irradiated in their forties showed no dose effect. Among all women who received at least 10 rads, those irradiated before age 20 years will have experienced the highest rates of breast cancer throughout their lifetimes. Separate excess risk estimates for Hiroshima and Nagasaki did not differ significantly, which indicates that for radiogenic breast cancer the effects of neutrons (emitted only in the Hiroshima explosion) and gamma radiation were about equal. Radiation did not reduce the latency period for the development of breast cancer, which was at least 10 years. The distribution of histologic types of cancers did not vary significantly with radiation dose. The data suggested that irradiation prior to menarche conferred a greater risk than irradiation after menarche.

    Background: Little is known about the epidemiology of suicide attempts among psychiatric outpatients in Mexico. This study was aimed to determine the socio-demographic, clinical and behavioral characteristics associated with suicide attempts in psychiatric outpatients in two public hospitals in Durango, Mexico. Methods: Two hundred seventy six psychiatric outpatients (154 suicide attempters and 122 patients without suicide attempt history) attended the two public hospitals in Durango City, Mexico were included in this study. Socio-demographic, clinical and behavioral characteristics were obtained retrospectively from all outpatients and compared in relation to the presence or absence of suicide attempt history. Results: Increased prevalence of suicide attempts was associated with mental and behavioral disorders due to psychoactive substance use (F10-19) (P=0.01), schizophrenia, schizotypal and delusional disorders (F20-29) (P=0.02), mood (affective) disorders (F30-39) (P<0.001), and disorders of adult personality and behavior (F60-69) (P<0.001). Multivariate analysis showed that suicide attempts were associated with young age (OR=1.21, 95% CI: 1.06-1.39; P=0.003), female gender (OR=2.98, 95% CI: 1.55-5.73; P=0.001), urban residence (OR=2.31, 95% CI: 1.17-4.57; P=0.01), memory impairment (OR=1.91, 95% CI: 1.07-3.40; P=0.02), alcohol consumption (OR=2.39, 95% CI: 1.21-4.70; P=0.01), and sexual promiscuity (OR=3.90, 95% CI: 1.74-8.77; P<0.001). Conclusions: We report the association of suicide attempts with socio-demographic, clinical and behavioral characteristics in psychiatric outpatients in Mexico. Results may be useful for an optimal planning of preventive measures against suicide attempts in psychiatric outpatients. PMID:24711751

    2011-01-01

    Background Reducing dietary energy density has proven to be an effective strategy to reduce energy intakes and promote weight control. This effect appears most robust when a low energy dense preload is consumed before meals. Yet, much discussion continues regarding the optimal form of a preload. The purpose of the present study was to compare effects of a solid (grapefruit), liquid (grapefruit juice) and water preload consumed prior to breakfast, lunch and dinner in the context of caloric restriction. Methods Eighty-five obese adults (BMI 30-39.9) were randomly assigned to (127 g) grapefruit (GF), grapefruit juice (GFJ) or water preload for 12 weeks after completing a 2-week caloric restriction phase. Preloads were matched for weight, calories, water content, and energy density. Weekly measures included blood pressure, weight, anthropometry and 24-hour dietary intakes. Resting energy expenditure, body composition, physical performance and cardiometabolic risk biomarkers were assessed. Results The total amount (grams) of food consumed did not change over time. Yet, after preloads were combined with caloric restriction, average dietary energy density and total energy intakes decreased by 20-29% from baseline values. Subjects experienced 7.1% weight loss overall, with significant decreases in percentage body, trunk, android and gynoid fat, as well as waist circumferences (-4.5 cm). However, differences were not statistically significant among groups. Nevertheless, the amount and direction of change in serum HDL-cholesterol levels in GF (+6.2%) and GFJ (+8.2%) preload groups was significantly greater than water preload group (-3.7%). Conclusions These data indicate that incorporating consumption of a low energy dense dietary preload in a caloric restricted diet is a highly effective weight loss strategy. But, the form of the preload did not have differential effects on energy balance, weight loss or body composition. It is notable that subjects in GF and GFJ preload

    Objectives: To investigate the illicit substance use trends by gender and year in Eastern Turkey, Elazığ. Methods: This is a retrospective study designed to assess the drug use prevalence in persons who admitted to the Probation Policlinic of Elazig Mental Health Hospital between January 2011 and December 2014 in Eastern Turkey, Elazığ. Laboratory screening tests for drugs were studied using the cloned enzyme donor immunoassay technique in urine. Results: The study consisted of 10267 males (95.3%) and 510 females (4.7%), with a mean age of 30.42±10.83 years. Overall prevalence was 32.1% for cannabis, 3.8% for opiate, 0.35% for cocaine and 1.2% for polydrug usage. The prevalence of cannabis was significantly higher in males (32.7%, p=0.000). The prevalence of cannabis use was the lowest in the age group of 50-59 while it was significantly higher in the age groups of 20-29 and 30-39 (p=0.000). The prevalence of opiate use showed a significant difference among the years (p=0.000). There was a significant difference in the prevalence of cocaine use among the years (p=0.02). The prevalence of polysubstance use showed a significant difference among years (p=0.000). Conclusion: Cannabis was the most common illicit drug in the east of the Turkey. Further studies are required for comparing the results of various regions of the country and developing early interventions and treatment facilities. PMID:27381538

    The association between long-term arsenic exposure and peripheral vascular disease has been well documented in our previous epidemiologic studies. The purpose of this study was to evaluate whether long-term arsenic exposure could be associated with ischemic heart disease (IHD). A total of 462 subjects living in the blackfoot disease-hyperendemic villages along the southwestern coast of Taiwan and characterized by long-term arsenic exposure from drinking artesian well water was studied. The subjects were recruited from an epidemiologic cohort who participated in a health examination. IHD was diagnosed by coding the resting electrocardiograms with the Minnesota code. History of arsenic exposure was estimated through information obtained from a personal interview according to a structured questionnaire and the arsenic content in artesian well water of the villages. Cumulative arsenic exposure (CAE) was calculated as the sum of the products multiplying the arsenic concentration in artesian well water (mg/l) by the duration of drinking the water (years) in consecutive periods of living in the different villages. Among the subjects, 78 cases (16.9%) were diagnosed as having IHD. The prevalence rates of IHD for the age groups of 30-39, 40-49, 50-59, and >/=60 years were 4.9, 7.5, 16.8, and 30.7%, respectively (P<0.001). For those with CAE of 0, 0.1-14.9 and >/=15 mg/l-years, the prevalence rates of IHD were 5.2, 10.9 and 24.1%, respectively (P<0.001). The odds ratios (95% confidence intervals) for IHD were 1.60 (0.48, 5.34), and 3.60 (1.11, 11.65), respectively, for those with CAE of 0.1-14.9 and >/=15.0 mg/l-years, when compared with those lacking drinking water exposure to arsenic after multivariate adjustment. It is concluded that IHD in the arseniasis-hyperendemic villages in Taiwan was associated with long-term arsenic exposure.

    Sleep deprivation, abnormal sleep patterns arising from working rotating shifts, and exposure to high ambient temperatures contribute to physical and cognitive dysfunction. We examined the effects of these on 19 (41.5 ± 5.1 years) male underground miners. Data were collected for 28 to 30 consecutive days such that the participants experienced their full rotating shift schedule, including days off. Objective measures of sleep quality (actigraphy), attentional capacity (psychomotor vigilance task), core body temperature (visceral pill), executive function (BRIEF-A) and subjective measures of fatigue (Karolinska and Epworth Sleepiness scales) were obtained over the 28-30 day period. Non-parametric analyses (χ(2), Wilcoxen Signed ranks) were used to determine differences between shift types and days off. Z-tests were used to compare sample data to population norms. These revealed that the participants experienced poor quality of sleep relative to age-matched norms irrespective of the shift being worked or if the participant was on a scheduled day off [30-39 year olds: z = -14.62, p < 0.001; 40-49 year olds: z = -4.44, p < 0.001]. Participants when working day shift experienced less sleep prior to beginning work compared to their days off or night shift; however, no differences in total sleep time between when participants worked day or night shifts were observed [χ(2) (2, n = 18) = 13.44, p < 0.01]. When measured subjectively, the only time participants reported excessive sleepiness was after a night shift. Objective measures of attentional capacity showed best performance at the beginning of night shifts in contrast to any other time that the task was completed; however, performance degraded dramatically over the course of the night shift [χ(2) (2, n = 12) = 6.50, p < 0.05]. We show that underground miners reported for work sleep deprived. The cognitive consequences of this poor sleep were most pronounced during night shift when their

    Blood pressure levels and related factors in Japanese, US whites and US blacks aged 30 to 74 years were compared, using data from the similarly designed national survey of each country in a similar period, i.e., the National Survey on Circulatory Disorders of Japan, 1980 (10,897 persons from all over Japan) and the second National Health and Nutrition Survey of the US, 1976 to 1980 (NHANES-II) (16,204 persons from all over the USA). Data collection methods were judged to be comparable. Data were stratified by age (30-39, 40-49, 50-59, 60-69, 70-74 yrs) and sex. Age-specific and age-adjusted mean systolic BPs of Japanese were generally higher than those of US whites; mean diastolic pressures were similar in the two populations in both men and women. Mean weight and body mass index (BMI) and their standard deviations were lower for Japanese than Americans. In US blacks, BP was higher than in Japanese or in US whites for diastolic in men, and for both systolic and diastolic in women. Systolic BP levels of black men were between those of Japanese and US whites. At specific levels of BMI, Japanese systolic BPs were markedly higher than those of US whites in all age-sex groups, and diastolic pressures were higher in Japanese than in US whites, slightly so at younger ages and more so at ages 60 and over in both sexes. The proportions of all persons with high BP who were receiving antihypertensive treatment and who were controlled were similar in most age-sex groups of the Japanese and US white populations; they were lower in US black men and higher in US black women. In linear regression analyses of BP on BMI controlled for age, slopes were similar for Japanese and Americans. However, given the lower mean BMI and smaller BMI standard deviation (less overweight), partial correlation coefficients between BMI and BP were smaller for Japanese than Americans. These results indicate that overweight plays a lesser role in Japanese than Americans in producing high prevalence

    Collection of marine invertebrates for use as fishing bait is a substantial activity in many parts of the world, often with unknown ecological consequences. As new fisheries develop, it is critical for environmental managers to have high quality ecological information regarding the potential impacts, in order to develop sound management strategies. Crab-tiling is a largely unregulated and un-researched fishery, which operates commercially in the south-west UK. The target species is the green crab Carcinus maenas. Those crabs which are pre-ecdysis and have a carapace width greater than 40 mm are collected to be sold to recreational anglers as bait. Collection involves laying artificial structures on intertidal sandflats and mudflats in estuaries. Crabs use these structures as refugia and are collected during low tide. However, the effect that this fishery has on populations of C. maenas is not known. The impact of crab-tiling on C. maenas population structure was determined by sampling crabs from tiled estuaries and non-tiled estuaries using baited drop-nets. A spatially and temporarily replicated, balanced design was used to compare crab abundance, sizes and sex ratios between estuaries. Typically, fisheries are associated with a reduction in the abundance of the target species. Crab-tiling, however, significantly increased C. maenas abundance. This was thought to be a result of the extra habitat in tiled estuaries, which probably provides protection from natural predators, such as birds and fish. Although crabs were more abundant in tiled estuaries than non-tiled estuaries, the overall percentage of reproductively active crabs in non-tiled estuaries was greater than in tiled estuaries. As with most exploited fisheries stocks, crabs in exploited (tiled) estuaries tended to be smaller, with a modal carapace width of 20-29 mm rather than 30-39 mm in non-tiled estuaries. The sex ratio of crabs however; was not significantly different between tiled and non

    Maxillofacial trauma is often associated with injuries to the cranium, especially in high-energy trauma. The management of such cases can be challenging and requires close cooperation between oral and maxillofacial surgery and neurosurgical teams. There are few reports in the current literature describing the complications that develop in patients with maxillofacial trauma and traumatic brain injury (TBI). Complications can be categorized as early or late and/or minor and major. The exact definition of complications and their categorization remains a matter of current debate. We present a 10 year retrospective study of complications and their subsequent management in patients receiving maxillofacial and neurosurgical treatment for maxillofacial trauma associated with TBI. The study population consisted of 47 people, excluded from a maxillofacial trauma population of 579 patients. The severity of the trauma was scored as mild, moderate or severe, using the Glasgow Coma Scale at presentation of the Emergency Department. In total 36 patients (76.6%) developed complications. Patients involved in road traffic collision were most likely to develop complications (92.3%). This was followed by falls (66.7%) as mechanism of the injury. Patients aged 60-69 years experienced the highest complication rate (5), followed by patients aged 20-29 years (4.1) and 30-39 years (3.5). The majority of complications were infection and inflammation (36.4%), followed by neurological deficit (24.0%), physiological dysregulation (11.6%) and facial bone deformity (8.3%). Patients who developed no complications, most often presented with mild TBI (72.7%). The most common treatment modality employed to manage complications was pharmacological, followed by antibiotic treatment, conservative treatment and decompression therapy. The mean hospital stay after the trauma for the patients with complications was 28 days. Thirteen patients (36.1%) were transferred to a rehabilitation centre, a nursing

    OBJECTIVES--To assess the effects of cigarette smoking on the incidence of non-fatal myocardial infarction, and to compare tar in different types of manufactured cigarettes. METHODS--In the early 1990s responses to a postal questionnaire were obtained from 13,926 survivors of myocardial infarction (cases) recently discharged from hospitals in the United Kingdom and 32,389 of their relatives (controls). Blood had been obtained from cases soon after admission for the index myocardial infarction and was also sought from the controls. 4923 cases and 6880 controls were current smokers of manufactured cigarettes with known tar yields. Almost all tar yields were 7-9 or 12-15 mg/cigarette (mean 7.5 mg for low tar (< 10 mg) and 13.3 for medium tar (> or = 10 mg). The cited risk ratios were standardised for age and sex and compared myocardial infarction rates in current cigarette smokers with those in non-smokers who had not smoked cigarettes regularly in the past 10 years. RESULTS--At ages 30-49 the rates of myocardial infarction in smokers were about five times those in non-smokers (as defined); at ages 50-59 they were three times those in non-smokers, and even at ages 60-79 they were twice as great as in non-smokers (risk ratio 6.3, 4.7, 3.1, 2.5, and 1.9 at 30-39, 40-49, 50-59, 60-69, 70-79 respectively; each 2P < 0.00001). After standardisation for age, sex, and amount smoked, the rate of non-fatal myocardial infarction was 10.4% (SD 5.4) higher in medium tar than in low tar cigarette smokers (2P = 0.06). This percentage was not significantly greater at ages 30-59 (16.6% (7.1)) than at 60-79 (1.0% (8.5)). In both age ranges the difference in risk between cigarette smokers and non-smokers was much larger than the difference between one type of cigarette and another (risk ratio 3.39 and 3.95 at ages 30-59 for smokers of similar numbers of low and of medium tar cigarettes, and risk ratio 2.35 and 2.37 at ages 60-79).

    The characteristics and correlates of high fertility women in Mexico were assessed for different age and residential groups with data from the National Demographic Survey of 1982. This survey included information on rural, urban and metropolitan Mexican women aged 15-49 years who had ever been in union. Rural areas were defined as those with fewer than 20,000 inhabitants. Metropolitan areas were Guadalajara, Monterrey, and Mexico City. High fertility was defined for the purpose of this study as at least 2 live births for women 15-19, 3 for women 20-24, 4 for those 25-29, 5 for those 30-34, 6 for those 35-39, and 7 for those 40-49. According to this definition about 40% of Mexican women are high fertility, with proportions ranging from about 1/3 of those 20-29 to half of those 35-49 years old. High fertility is about twice as common in women 15-19 in rural areas as in urban and metropolitan areas of Mexico. 10% of rural women aged 20-24 already have 5 children, compared to less than 1% of metropolitan women and under 3% of women in other urban areas. By age 45-49, 31% of rural women, 20% of other urban women, and 15% of metropolitan women have 10 or more children. 13% in all areas have 2 or 3. Large proportions of rural women in all age groups are high fertility, with the difference especially marked at young ages. The data on contraceptive usage indicate that high fertility women are among the increasing numbers of Mexican women attempting to control their family size. 10% of high fertility women in rural areas are sterilized and another 10% use oral contraceptives. Injectables and traditional methods share 3rd place. IUDs are almost nonexistent in rural areas. In urban and metropolitan zones about 1/4 of high fertility women have been sterilized. About 10% use pills. Traditional methods and IUDs are in 3rd place for urban women while injectables occupy 3rd place for metropolitan women. Except among women 30-34, about 70% of sterilizations in rural areas are in

Among age group 50-59 years Genotype 1 was most common in male patients (29.05 % of 148) followed in 20-29 years (23.65 % of 148), genotype 2 in the age group 60-69 (12 cases of 31) and genotype 3 in the age group 50-59 (4 cases of 13) and genotype 6 was most frequent in the age group 30-39 (4 cases of 7). The frequency of HCV prevalence was significantly higher in female patients compared to males before ages 60, while the opposite result was observed after 60 years. The most common HCV genotype in WuHan was subtype 1b followed by 2a and more common among women than males patients. Further studies are needed to collect a large number of samples to estimate the different epidemiology of the HCV genotypes, because the sample size of non-genotype 1b and 2a is not large enough and other factors like disease history/monthly income/etc. are not included in our study.

    2016-01-01

    Background Health care literature supports the development of accessible interventions that integrate behavioral economics, wearable devices, principles of evidence-based behavior change, and community support. However, there are limited real-world examples of large scale, population-based, member-driven reward platforms. Subsequently, a paucity of outcome data exists and health economic effects remain largely theoretical. To complicate matters, an emerging area of research is defining the role of Superusers, the small percentage of unusually engaged digital health participants who may influence other members. Objective The objective of this preliminary study is to analyze descriptive data from GOODcoins, a self-guided, free-to-consumer engagement and rewards platform incentivizing walking, running and cycling. Registered members accessed the GOODcoins platform through PCs, tablets or mobile devices, and had the opportunity to sync wearables to track activity. Following registration, members were encouraged to join gamified group challenges and compare their progress with that of others. As members met challenge targets, they were rewarded with GOODcoins, which could be redeemed for planet- or people-friendly products. Methods Outcome data were obtained from the GOODcoins custom SQL database. The reporting period was December 1, 2014 to May 1, 2015. Descriptive self-report data were analyzed using MySQL and MS Excel. Results The study period includes data from 1298 users who were connected to an exercise tracking device. Females consisted of 52.6% (n=683) of the study population, 33.7% (n=438) were between the ages of 20-29, and 24.8% (n=322) were between the ages of 30-39. 77.5% (n=1006) of connected and active members met daily-recommended physical activity guidelines of 30 minutes, with a total daily average activity of 107 minutes (95% CI 90, 124). Of all connected and active users, 96.1% (n=1248) listed walking as their primary activity. For members who

    A community-based cross-sectional study was conducted in brothel-based sex workers of West Bengal, Eastern India, to determine their oncogenic human papillomavirus (HPV) status and the presence of pre-cancerous lesions. A total of 229 sex workers from three districts of West Bengal participated in the study. All the study participants were interviewed with the aid of a pre-tested questionnaire to determine their sociodemographics, risk behaviour and risk perceptions after obtaining informed verbal consent. The interview was followed by collection of cervical cells from all participants using a disposable vaginal speculum and cervical cytobrush. Oncogenic HPV DNA was detected by real-time polymerase chain reaction (PCR). A simultaneous Papanicolaou test ('Pap smear') was performed to detect cervical cytological abnormalities. Overall, the prevalence of oncogenic HPV was found to be 25% (58/229) among the studied population. A subset (n=112) of the sample was tested separately to determine the existence and magnitude of HPV genotypes 16 and 18. The results showed that genotype 16 was prevalent in 10% (11/112), genotype 18 in 7% (8/112) and both genotype 16 and 18 in 7% (8/112). The HPV prevalence rate showed a decreasing trend with age, being 71.4% in the 10-19 years age group, 32.3% in the 20-29 years age group, 18.3% in the 30-39 years age group and 2.5% in the >or=40 years age group (statistically significant differences, P1 year, respectively. This difference was found to be statistically significant both by univariate and multivariate analysis. In this study, it was observed that sex workers with an average number of daily clients of six or more had an HPV prevalence of 67% (n=6), those with four to five clients had a prevalence of 45% (n=9), those with two to three clients had a

    Microbial transformation of the antimelanoma agent betulinic acid was studied. The main objective of this study was to utilize microorganisms as in vitro models to predict and prepare potential mammalian metabolites of this compound. Preparative-scale biotransformation with resting-cell suspensions of Bacillus megaterium ATCC 13368 resulted in the production of four metabolites, which were identified as 3-oxo-lup-20(29)-en-28-oic acid, 3-oxo-11α-hydroxy-lup-20(29)-en-28-oic acid, 1β-hydroxy-3-oxo-lup-20(29)-en-28-oic acid, and 3β,7β,15α-trihydroxy-lup-20(29)-en-28-oic acid based on nuclear magnetic resonance and high-resolution mass spectral analyses. In addition, the antimelanoma activities of these metabolites were evaluated with two human melanoma cell lines, Mel-1 (lymph node) and Mel-2 (pleural fluid). PMID:10966400

    2016-09-01

    We have re-estimated overdiagnosis of breast cancer from mammography screening by age group in the Canadian National Breast Screening Study (CNBSS), a randomized screening trial. In the CNBSS, participants were recruited in 15 centers. 89,835 women were randomized with informed consent, 50,430 age 40-49 and 39,405 age 50-59. Women aged 40-49 received annual mammography and physical examination (MA+PX) versus a single physical examination and usual care in the community (UC). Women aged 50-59 received (MA+PX) versus (PX-alone) annually. Individual randomization resulted in 44 almost identically distributed demographic and risk factors. Annual compliance over the five or four scheduled screens was 86-95%. The cumulative numbers of invasive and in situ breast cancers ascertained by year during screening and subsequent follow-up to 25 years post entry to the CNBSS in the mammography arm have been compared to those in the control arm. Estimates of overdiagnosis were derived using post-screening cessation cut-off points from 1 to 20years.⋯Overdiagnosis of invasive breast cancer at five years post cessation of screening for women aged 40-49 was estimated to be 32%, and 16% for women aged 50-59; 20years post cessation of screening 48% for women 40-49 and 5% for those 50-59. Including ductal carcinoma in situ with invasive cancer, estimates were 41%, 25%, 55% and 16%, respectively. We conclude that approximately 30% of invasive screen-detected breast cancers in women age 40-49 were overdiagnosed, and 20% of those screen-detected in women age 50-59. Including ductal carcinoma in situ, the estimates are 40% and 30%, respectively. PMID:27374944

    According to the Singapore National Health Survey (NHS) of 2010, the population of the Republic of Singapore was 5.076,700, comprising four ethnic groups: Chinese (74.1%), Malays (13.4%), Indians (9.2%), and others (3.3%). The National Health Survey for 2016 is under way and due to be published in 2017. From the six-yearly national health surveys, the crude prevalence of clinical hypertension (HTn), defined as a sustained blood pressure ≥ 140/90 mmHg, in Singaporean residents aged 30 to 69 years rose from 22.2% in 1992 to 27.3% in 1998, but declined to 24.9% (2004) and to 23.5% in 2010.The NHS of 2010 demonstrated that 18.9% of residents aged 18 to 69 years (an age band of 52 years) had hypertension.

    According to the Singapore National Health Survey (NHS) of 2010, the population of the Republic of Singapore was 5.076,700, comprising four ethnic groups: Chinese (74.1%), Malays (13.4%), Indians (9.2%), and others (3.3%). The National Health Survey for 2016 is under way and due to be published in 2017. From the six-yearly national health surveys, the crude prevalence of clinical hypertension (HTn), defined as a sustained blood pressure ≥ 140/90 mmHg, in Singaporean residents aged 30 to 69 years rose from 22.2% in 1992 to 27.3% in 1998, but declined to 24.9% (2004) and to 23.5% in 2010.The NHS of 2010 demonstrated that 18.9% of residents aged 18 to 69 years (an age band of 52 years) had hypertension. Its data show that the age-specific prevalence of HTn rises in a pronounced way from the age of 40 years (16.7%) onwards. The age-specific prevalence of the disorder was 53.4% in persons aged 60-69 years, compared with 7.6% in those aged 30-39 years.The 2010 NHS showed, as have surveys in many other industrial nations, that more men (prevalence = 26.4%) than women (20.7%) have HTn.

  18. Markov models of breast tumor progression: some age-specific results.

    PubMed

    Duffy, S W; Day, N E; Tabár, L; Chen, H H; Smith, T C

    1997-01-01

    Researchers have noted that mammographic screening has a reduced effect on breast cancer mortality in women in their forties compared to older women. Explanations for this include poorer sensitivity in younger women due to denser breast tissue, as well as more rapid tumor progression, giving a shorter mean sojourn time (the average duration of the preclinical screen-detectable period). To test these hypotheses, we developed a series of Markov-chain models to estimate tumor progression rates and sensitivity. Parameters were estimated using tumor data from the Swedish two-county trial of mammographic screening for breast cancer. The mean sojourn time was shorter in women aged 40-49 compared to women aged 50-59 and 60-69 (2.44, 3.70, and 4.17 years, respectively). Sensitivity was lower in the 40-49 age group compared to the two older groups (83%, 100%, and 100%, respectively). Thus, both rapid progression and poorer sensitivity are associated with the 40-49 age group. We also modeled tumor size, node status, and malignancy grade together with subsequent breast cancer mortality and found that, to achieve a reduction in mortality commensurate with that in women over 50, the interscreening interval for women in their forties should be less than two years. We conclude that Markov models and the use of tumor size, node status, and malignancy grade as surrogates for mortality can be useful in design and analysis of future studies of breast cancer screening.

    2002-01-01

    In 1996, a seroepidemiological study was undertaken in Spain, with the main aim of estimating the population's immunity against poliomyelitis, tetanus and diphtheria. A population-based cross-sectional study was conducted, covering the population aged 2-39 years. The sample was stratified by age and rural-urban environment, and informed consent obtained to take blood specimens from subjects attending phlebotomy centres. The study included 3,932 persons and the prevalence of antibodies against all three types of poliovirus exceeded 94% across all age groups. From a high of 96% in subjects under the age of 15 years, immunity against diphtheria steadily declined to a low of 32.3% in subjects aged 30-39 years. Similarly, tetanus antitoxin concentrations indicating basic protection were present in 98.9% of the under-14 years age group; thereafter, immunity declined, until reaching 54.6% in the 30-39 years age group.

  15. Breakout character of islet amyloid polypeptide hydrophobic mutations at the onset of type-2 diabetes

    NASA Astrophysics Data System (ADS)

    Frigori, Rafael B.

    2014-11-01

    Toxic fibrillar aggregates of islet amyloid polypeptide (IAPP) appear as the physical outcome of a peptidic phase transition signaling the onset of type-2 diabetes mellitus in different mammalian species. In particular, experimentally verified mutations on the amyloidogenic segment 20-29 in humans, cats, and rats are highly correlated with the molecular aggregation propensities. Through a microcanonical analysis of the aggregation of IAPP20 -29 isoforms, we show that a minimalist one-bead hydrophobic-polar continuum model for protein interactions properly quantifies those propensities from free-energy barriers. Our results highlight the central role of sequence-dependent hydrophobic mutations on hot spots for stabilization, and thus for the engineering, of such biological peptides.

  16. Fibrillar dimer formation of islet amyloid polypeptides

    NASA Astrophysics Data System (ADS)

    Chiu, Chi-cheng; de Pablo, Juan J.

    2015-09-01

    Amyloid deposits of human islet amyloid polypeptide (hIAPP), a 37-residue hormone co-produced with insulin, have been implicated in the development of type 2 diabetes. Residues 20 - 29 of hIAPP have been proposed to constitute the amyloidogenic core for the aggregation process, yet the segment is mostly unstructured in the mature fibril, according to solid-state NMR data. Here we use molecular simulations combined with bias-exchange metadynamics to characterize the conformational free energies of hIAPP fibrillar dimer and its derivative, pramlintide. We show that residues 20 - 29 are involved in an intermediate that exhibits transient β-sheets, consistent with recent experimental and simulation results. By comparing the aggregation of hIAPP and pramlintide, we illustrate the effects of proline residues on inhibition of the dimerization of IAPP. The mechanistic insights presented here could be useful for development of therapeutic inhibitors of hIAPP amyloid formation.

    Fetal obstructive bowel disease was diagnosed in 29 patients at 22-37 weeks (median 32 weeks) of gestation, seven (24 per cent) of whom also displayed other anomalies. Polyhydramnios was present in 20/29 cases (69 per cent). An abnormal karyotype existed in 7/29 cases (24 per cent), of which six were diagnosed prenatally (trisomy 21, n = 5; 69,XXX, n = 1) and one postnatally (trisomy 21). There was always an association with the ultrasonic 'double bubble' sign. Obstructive bowel disease was confirmed postnatally in 20/29 (69 per cent) cases, i.e., oesophageal atresia (n = 1), duodenal obstruction (n = 12), and small bowel obstruction (n = 7). Other anomalies existed in 6/29 (21 per cent) cases, i.e., multicystic kidney (n = 1) and multiple congenital anomalies (n = 5). The perinatal mortality rate was 35 per cent (7/20). PMID:7877951

  20. Mammography outcomes in a practice setting by age: prognostic factors, sensitivity, and positive biopsy rate.

    PubMed

    Linver, M N; Paster, S B

    1997-01-01

    The separate unplanned analysis of women ages 40-49 in population-based randomized controlled trials has resulted in demonstration of statistically significant breast cancer mortality reduction due to screening mammography in only two of the individual trials, and in all such trials only through meta-analysis. Therefore, many researchers have utilized the surrogate endpoints of tumor size and axillary lymph node status to evaluate screening efficacy. For the present study, these endpoints were evaluated in an audit of 854 screen-detected cancers found in 147,125 mammographic examinations performed in women over 40 between 1988 and 1994 in a community practice setting. The concerns that mammography in the 40-49 group has a lower sensitivity and higher biopsy rate were also addressed. Median invasive tumor size and lymph node positivity were found to be equally small (1.0-1.1 cm and 13.5-12.2%, respectively), and the sensitivity and overall biopsy rate were found to be constant over all ages 40 and above. Positive biopsy rate (PBR) varied directly with increasing age, paralleling the measured cancer detection rate in each decade, with no abrupt change at age 50. We conclude that modern mammography in a community practice setting can successfully detect breast cancers with favorable prognostic factors and achieve constant sensitivity and acceptable PBRs in all women over 40. Our data also suggest that many of the large differences seen by inappropriately dividing data at age 50 decrease or disappear when analysis is performed by decade.

    Microbial transformation studies of the antimelanoma agent betulinic acid (1) were conducted. Screening experiments showed a number of microorganisms capable of biotransforming 1. Three of these cultures, Bacillus megaterium ATCC 14581, Cunninghamella elegans ATCC 9244, and Mucor mucedo UI-4605, were selected for preparative scale transformation. Bioconversion of 1 with resting-cell suspensions of phenobarbital-induced B. megaterium ATCC 14581 resulted in the production of the known betulonic acid (2) and two new metabolites: 3beta,7beta-dihydroxy-lup-20(29)-en-28-oic acid (3) and 3beta,6alpha, 7beta-trihydroxy-lup-20(29)-en-28-oic acid (4). Biotransformation of 1 with growing cultures of C. elegans ATCC 9244 produced one new metabolite characterized as 1beta,3beta, 7beta-trihydroxy-lup-20(29)-en-28-oic acid (5). Incubation of 1 with growing cultures of M. mucedo UI-4605 afforded metabolite 3. Structure elucidation of all metabolites was based on NMR and HRMS analyses. In addition, the antimelanoma activity of metabolites 2-5 was evaluated against two human melanoma cell lines, Mel-1 (lymph node) and Mel-2 (pleural fluid).

    Resolution no. 30.39 of the WHA, passed in May 1977, recommends the adoption of SI units by the medical community throughout the world, including a change from mmHg to kPa. In Austria this requirement has been law since January 1978. This paper describes how simply the transition can be made and how other results, such as those of tonography and differential tonometry, are numerically altered as a result. Finally a simple modification is described which enables the Goldmann tonometer to indicate intraocular pressure, its kPa being equal to g on the scale.

    A micro-level investigation of 983 pregnant women (aged 15-49 years) regarding sex determination and associated factors was carried out in a periurban region of Northern India. Among the women surveyed, 183 chose to use sex determination. The highest percentage of sex determination was among 30-39-year-old women, and general caste and family size were two risk factors associated with sex determination. Correcting imbalances in sex ratios at birth is a complex issue without easy answers, especially in patriarchal societies. Apart from raising awareness among decisionmakers, property rights in favor of women and strict vigilance and record of registration of ultrasound machines are necessary. PMID:23066964

    A modified monopolar electrocoagulation probe for endoscopic treatment of gastrointestinal bleedings in special situations is described. The tip of the active electrode may be moved foreward or drawn back into a teflon catheter. Thereby, blood clots are removed from the tip of the probe. The device is easy to use, reliable in emergency endoscopies and can be employed with conventional high-frequency diathermy instruments. The probe is inexpensive. 49 patients with active gastrointestinal bleedings according to Forrest Ib were treated. In 40/49 patients permanent hemostasis could be achieved. In 4/49 patients recurrent bleedings were controlled after repeated electro-coagulation. 4/49 patients needed elective operation, one patient emergency operation. Complications by application of the described monopolar electrocoagulation probe did not occur. The area of necrosis according to electrocoagulation was small. PMID:1926958

The work is also associated with significant levels of noise, minor artificial illumination, air pollution with dust and unfavorable microclimate. By the end of working shift the drivers demonstrate marked changes in blood pressure, prolonged oculomotor reactions, depressed visual function. Morbidity with transitory disablement is high among the drivers, presenting especially cardiovascular and gastrointestinal diseases. Unfavorable changes of ageing process are seen in the drivers over 35, in age group of 40-49 years (with length of service at least 20 years). The complex investigations helped to elaborate hygienic norms for new subway cars, to base rational schedule ot work and rest for the drivers. PMID:7767606

    A study was performed to assess differences in the clinical presentation of tuberculosis between two groups of immigrants. Ninety-four patients seen in the emergency room for newly diagnosed tuberculosis between 2006 and 2012 were included. Forty-nine patients were from Asian countries and 45 from Latin America. Mean age [years (SD)] was 35.3 (13) in Asian patients and 33.9 (10) in Latin American patients. Asian subjects were predominantly male (40/49 vs 25/45; P=0.006). Patients from Latin American countries had a higher rate of pulmonary tuberculosis. A higher percentage of Asian patients lived in overcrowded conditions, whereas HIV infection was more frequent among Latin Americans. Most patients were treated with a quadruple regimen. Resistance to isoniazid was documented in two patients from Latin America.

An online questionnaire was completed by 1,772 staff and physicians from five hospitals and two primary care centres in Montreal. Low levels of knowledge and significant associations between knowledge and occupational group, age, and contact with refugees were documented. Social workers, respondents aged 40-49 years, and those who reported previous contact with refugee claimants seeking healthcare were significantly more likely to have 2 or more correct responses. Rapid and multiple changes to the complex IFH policy have generated a high level of confusion among healthcare providers. Simplification of the system and a knowledge transfer strategy aimed at improving healthcare delivery for IFH patients are urgently needed, proposing easy avenues to access rapidly updated information and emphasizing ethical and clinical issues.

    Small airborne particles less than 1 microm in diameter have a high probability to deposit deeply in the respiratory tract and cause respiratory diseases such as lung cancer. In this study, emission characteristics of submicron particles from a direct injection diesel engine using biodiesel (provided by the American Soybean Association) and petroleum-diesel fuels were measured under different operation conditions. The results show that the emitted particle sizes for both fuels are about the same. But when fueled with biodiesel, the diesel engine can substantially reduce 24-42% emission of the total number concentration, and 40-49% of the total mass concentration of submicron particles, which indicates that the emission of submicron particles can be effectively approved.

    Cycloartenol synthase converts oxidosqualene to cycloartenol, the first carbocyclic intermediate en route to sterols in plants and many protists. Presented here is the first cycloartenol synthase gene identified from a protist, the cellular slime mold Dictyostelium discoideum. The cDNA encodes an 81-kDa predicted protein 50-52% identical to known higher plant cycloartenol synthases and 40-49% identical to known lanosterol synthases from fungi and mammals. The encoded protein expressed in transgenic Saccharomyces cerevisiae converted synthetic oxidosqualene to cycloartenol in vitro. This product was characterized by 1H and 13C nuclear magnetic resonance and gas chromatography-mass spectrometry. The predicted protein sequence diverges sufficiently from the known cycloartenol synthase sequences to dramatically reduce the number of residues that are candidates for the catalytic difference between cycloartenol and lanosterol formation.

Data were obtained through home interviews on nutritional status and socio-demographic and health conditions. Of the total sample, 53.3% were females. Median BMI was 26.40 kg/m² (range = 15.20-46.82) and was lower for men than for women. Prevalence of overweight was high (45%; 95%CI: 40%-49%), decreased with age, was positively associated with female gender and history of arthritis/arthrosis, and was negatively associated with age 80 years or older and smoking. Prevalence of underweight was high in men (18.2%), increased with age, and was positively associated with worse self-rated health. The findings highlight the importance of health strategies that favor lifestyle changes and healthy eating habits.

    There has been a 28% reduction in age-standardised breast cancer mortality in Australia since 1991 when the free national mammographic program (BreastScreen) began. Therefore, a comparative study between BreastScreen participation and breast cancer age specific mortality trends in Australia was undertaken for two time periods between 1991 and 2007, where women aged 50-59 and 60-69 years, who were invited to screen, were compared to women aged 40-49 and 70-79 years who were not invited, but who did have access to the program. There were mortality reductions in all four age groups between 1991-1992 and 2007, resulting in 5,849 (95% CI 4,979 to 6,718) fewer women dying of breast cancer than would have otherwise been the case. Women aged 40-49 years, who had the lowest BreastScreen participation (approximately 20%), had the largest mortality reduction: 44% (95% CI 34.8-51.2). Women aged 60-69 years, who had the highest BreastScreen participation (approximately 60%), had the smallest mortality reduction: 19% (95% CI 10.5-26.9). As BreastScreen participation by invited women aged 50-69 years only reached a maximum of about 55-60% in 1998-1999, a decline in mortality in Australian women cannot be attributed to BreastScreen prior to this time. Thus, almost 60% of the Australian decline in breast cancer mortality since 1991 cannot be attributed to BreastScreen. Therefore, mammographic screening cannot account for most of the reductions in breast cancer mortality that have occurred in Australian women since 1991 and may have contributed to over-diagnosis. Most, if not all, of the reductions can be attributed to the adjuvant hormonal and chemotherapy, which Australian women have increasingly received since 1986.

    STUDY OBJECTIVE: To evaluate a population based screening programme for breast cancer. DESIGN: This was a case-control study of women dying of breast cancer between 1977 and 1987 who had been invited to take part in a screening programme. SETTING: Community based study of women aged between 40 and 70 years (total population about 35,000 at 1981 census), living in 23 small towns near Florence, Italy. PARTICIPANTS: 103 cases were identified from death certification, and 515 living controls (five per case) selected for year of birth and town of residence. MEASUREMENTS AND MAIN RESULTS: Screening history was obtained from computer archive. Sociodemographic information was obtained from town registry offices and directly from relatives of the deceased and from the controls by postal questionnaire, and if necessary telephone or personal interview. Analysis was carried out on two age groups--40-49 years and 50+ years at diagnosis--and considered the number of screening tests and the time interval since the last test, separately and together. In the older age group, women with at least one screening test in the previous 2 1/2 years showed a 50% reduction in risk (odds ratio 0.49, 95% confidence interval [CI] 0.25-0.95). If they had also had another previous negative screen the risk was reduced to one third (odds ratio 0.35, 95% CI 0.14-0.85). There was a significant trend of decreasing risk with increasing number of screens in older women. No clear evidence of a similar protective effect was shown for women in the 40-49 year age group. CONCLUSIONS: A significant protective effect of the screening programme is evident in older women but not in younger ones. The data do not allow an assessment of optimal screening interval because of the small number of previously screened cases. PMID:2607303

Among 739 participants, prevalence rates were 31.8% and 10.2% for overweight and obesity, respectively, and 55.7% for increased waist-to-height ratio (> 0.50). Prevalence of overweight was higher among 30-39-year-olds, while abdominal obesity was more frequent among older individuals. Female sex, eating chicken or beef with untrimmed fat, and hypertension were associated with higher odds of overweight and abdominal obesity, while smoking and single marital status were associated with lower odds. The results show high prevalence rates for overweight and abdominal obesity in these very poor and socially isolated communities. Specific preventive and control measures are urgently needed.

    The oesophageal groove reflex was examined in 6 milk-fed Holstein Friesian calves once weekly during the first 17 weeks of life. Additionally, the effect of different feeding methods (bucket, different nipple positions and openings), different milk temperatures (20, 30, 39, 45°C) and milk replacer concentrations (100, 125, 150 grams/litre of water) on oesophageal groove closure was investigated. The reticulum and abomasum were examined ultrasonographically using a 5.0-MHz convex transducer before, during and after feeding, and the oesophageal groove reflex was considered to be functional when milk was seen entering the abomasum during feeding. The reflex was consistently induced throughout the study period in all calves at all examinations and under all experimental conditions. However, it should not be assumed that feeding technique can be neglected in unweaned calves because suboptimal feeding management has been linked to various digestive disorders. PMID:26753366

    Mountain biking is increasing in popularity worldwide. The injury patterns associated with elite level and competitive mountain biking are known. This study analysed the incidence, spectrum and risk factors for injuries sustained during recreational mountain biking. The injury rate was 1.54 injuries per 1000 biker exposures. Men were more commonly injured than women, with those aged 30-39 years at highest risk. The commonest types of injury were wounding, skeletal fracture and musculoskeletal soft tissue injury. Joint dislocations occurred more commonly in older mountain bikers. The limbs were more commonly injured than the axial skeleton. The highest hospital admission rates were observed with head, neck and torso injuries. Protective body armour, clip-in pedals and the use of a full-suspension bicycle may confer a protective effect.

    The cardiovascular response to 1 h of 60-deg head-down tilt was studied in 12 male subjects, ages 30-39 years, to simulate the early effects of weightlessness. Fluid shifts, hemodynamic variables, and indices of myocardial contractility were evaluated by utilizing electrocardiography, systolic time intervals, impedance cardiography, sphygmomanometry, and measurement of calf circumference. Most cardiovascular variables remained stable throughout the initial 30 min of the protocol, even though translocation of fluid from the legs to the thorax commenced immediately with the onset of head-down tilt. In contrast, minutes 30-60 were characterized by reduced stroke volume, cardiac output, mean stroke ejection rate, and Heather index concomitant with an elevation in mean arterial pressure. Intrathoracic fluid volume continued to increase, while leg volume continued to decrease. This latter physiological response suggests intrathoracic sequestration of fluid volume; blood was apparently redistributed to the pulmonary circulation rather than being retained in the great veins.

    Cardiovascular responses to lower-body negative pressure (LBNP) were studied following 1 hour of 6-deg head-down tilt to determine whether a redistribution of blood volume toward the central circulation modifies the subsequent response to orthostatic stress. Responses of 12 men, ages 30-39 years, were evaluated by electrocardiography, impedance cardiography, sphygmomanometry, and measurement of calf circumference. During the LBNP that followed head-down tilt, as compared with control LBNP (no preceding head-down tilt) subjects, had smaller stroke volume and cardiac output, greater total peripheral resistance, and less calf enlargement. These differences reflect differences in the variables immediately preceding LBNP. Magnitudes of the responses from pre-LBNP to each pressure stage of the LBNP procedure did not differ between protocols. Mean and diastolic arterial pressures were slightly elevated after LBNP-control, but they fell slightly during LBNP post-tilt.

    This study sought to identify the magnitude of HIV risk in a diverse sample of Men who use the Internet to seek Sex with Men (MISM), and test if specific subpopulations are at sufficiently increased risk to warrant tailored interventions. A sample of 2,716 American MISM, stratified by race/ethnicity, completed an Internet survey of online and offline sex seeking behavior during the last 3 months. Across most demographics, a minority of MISM reported unprotected anal intercourse with male partners (UAIMP). Across all demographics, risk of UAIMP substantially increased with partners met online. Other predictors of increased online partner risk include being 30-39 years old, having children, not living in the Northeast, and low income. HIV-positive men and African Americans reported increased online and offline partner risk. To address higher risk of UAIMP, online HIV interventions should prioritize the needs of MISM, especially HIV-positive men, with content focused on online-mediated liaisons.

    This service evaluation aimed to characterise the referrals to the premature ovarian failure clinic, including the type of referral and patient needs, in order to plan for future service provision. The majority of women seen in the clinic experienced idiopathic premature ovarian failure, were aged 30-39 and were nulliparous at the time of diagnosis. Our service requires to be tailored to their needs. For many women, this includes a fertility consultation in the clinic and this part of the service is well used. Our data support the long-term follow-up of women both on treatment and those who initially decline treatment. Most women who initially decline treatment accept it after a few clinic visits. This may be due to consistent advice on the benefits of oestrogen treatment or due to yearly bone scans showing a change in bone density. There was a high non-attendance rate in this group: 21% of appointments were not attended. PMID:22519481

    Because sex ratios at birth have risen sharply in China in recent decades, an increasing proportion of men will be unable to find a bride, and will face old age without the support of a wife and children. We project the proportions of never-married men and their geographical distribution in China in the coming decades. Our projections assume that two tendencies in current marriage patterns will persist: that women will continue to migrate to wealthier areas and to prefer men with better prospects. We find that, by 2030, more than 20 per cent of men in China aged 30-39 will never have married, and that the proportion will be especially high among poor men in low-income provinces that are least able to provide social protection programmes. The projected geographic concentration of bachelors could be socially disruptive, and the results suggest a need to expand the coverage and central financing of social protection programmes.

    The present study was part of a larger randomized controlled childhood obesity prevention trial based in 11 public recreation centers. The primary aim was to evaluate the effectiveness of a multi-level intervention to prevent the onset of overweight and obesity among children (5-8 years of age). However, the purpose of the current study was to identify sociodemographic variables, such as acculturation, that were associated with receipt of physician advice among Latino primary caregivers. Participants included 221 Latino primary caregivers and their children from San Diego, CA. Cross-sectional baseline data suggested that Latino children with private insurance were more likely to receive physician advice regarding their eating habits. Conversely, primary caregivers between the ages of 30-39 were less likely to receive physician advice regarding their child's eating habits. Current findings highlight the continued need to improve preventive efforts and reduce health disparities among a vulnerable population, such as Latinos.

    We introduce a new microscopic model of cascading failures in transmission power grids. This model accounts for automatic response of the grid to load fluctuations that take place on the scale of minutes, when optimum power flow adjustments and load shedding controls are unavailable. We describe extreme events, caused by load fluctuations, which cause cascading failures of loads, generators and lines. Our model is quasi-static in the causal, discrete time and sequential resolution of individual failures. The model, in its simplest realization based on the Directed Current description of the power flow problem, is tested on three standard IEEE systems consisting of 30, 39 and 118 buses. Our statistical analysis suggests a straightforward classification of cascading and islanding phases in terms of the ratios between average number of removed loads, generators and links. The analysis also demonstrates sensitivity to variations in line capacities. Future research challenges in modeling and control of cascading outages over real-world power networks are discussed.

  13. Ultrasonographic examination of the oesophageal groove reflex in young calves under various feeding conditions.

    2015-08-01

    The oesophageal groove reflex was examined in 6 milk-fed Holstein Friesian calves once weekly during the first 17 weeks of life. Additionally, the effect of different feeding methods (bucket, different nipple positions and openings), different milk temperatures (20, 30, 39, 45°C) and milk replacer concentrations (100, 125, 150 grams/litre of water) on oesophageal groove closure was investigated. The reticulum and abomasum were examined ultrasonographically using a 5.0-MHz convex transducer before, during and after feeding, and the oesophageal groove reflex was considered to be functional when milk was seen entering the abomasum during feeding. The reflex was consistently induced throughout the study period in all calves at all examinations and under all experimental conditions. However, it should not be assumed that feeding technique can be neglected in unweaned calves because suboptimal feeding management has been linked to various digestive disorders.

    In order to assess the immunity to rubella infection in Dongguan, China, we conducted a seroprevalence survey on rubella and used ELISA to measure rubella-specific IgG in serum samples. A total of 1,017 individuals aged 0-59 years were selected by multistage cluster sampling. Among them, 904 (88.9%) were seropositive for rubella. Two groups (20-29 and ≥40 years) had seropositivity rates of <90%. In comparison with participants aged ≥20 years, rubella immunization rates were higher in those aged <20 years (83.2% vs. 93.7%, respectively; χ(2) = 28.063, P < 0.001). Among women aged 20-29 years, only 63.8% had antibodies above the protective level. Multivariate analysis revealed that only sex and age were significantly associated with rubella-protective antibody levels. Our results suggest that in the study area, women of childbearing age had a greater serological susceptibility to rubella. Additional vaccinations for rubella of susceptible young adults should be considered, particularly in women of childbearing age.

    Euonymus alatus (Celastraceae) has been used as an anticancer agent in Korean traditional medicine. However, the potential bioactive contributors to the anticancer effects have not been thoroughly studied. Our screening test revealed that the MeOH extract of E. alatus twigs exhibited significant cytotoxicity against A549, SK-OV-3, and SK-MEL-2 cell lines. A bioassay-guided separation of the MeOH extract of E. alatus twigs resulted in the isolation and identification of 14 triterpenes as main phytochemicals. The structures of the compounds were elucidated on the basis of spectroscopic evidence as lupeol (1), betulin (2), 3β,28,30-lup-20(29)-ene triol (3), lupenone (4), betulone (5), 28,30-dihydroxy-3-oxolup-20(29)-ene (6), messagenin (7), glut-5-en-3β-ol (8), maslinic acid (9), hederagenin (10), 3-oxo-11α-methoxyolean-12-ene (11), 3β-hydroxy-1-oxo-olean-12-en-28-oic acid (12), ursolic acid (13), and 2a-hydroxy- ursolic acid (14). Of these compounds, 3, 6-8, and 10-14 were isolated for the first time from this plant. All isolated triterpenoids had consistent antiproliferative activities against A549, SK-OV-3, SK-MEL-2, and HCT-15 cell lines. Compounds 2, 5, and 7 showed significant cytotoxicity against all four cell lines tested, with IC50 values of 3.26-8.61 µM. PMID:26749829

    A novel series of N-benzenesulfonyl-1,2,3,4-tetrahydroisoquinolines (14-33) containing triazole moiety were designed and synthesized through rational cycloadditions using the modified Pictet-Spengler reaction and the Click chemistry. Antiproliferative activity against four cancer cell lines (e.g., HuCCA-1, HepG2, A549 and MOLT-3) revealed that many substituted triazole analogs of benzoates (20, 29) and benzaldehydes (30, 32) exhibited anticancer activity against all of the tested cancer cell lines in which the ester analog 20 was shown to be the most potent compound against HuCCA-1 (IC50 = 0.63 μM) and A549 (IC50 = 0.57 μM) cell lines. Triazoles bearing phenyl (15, 24), tolyl (26, 27), acetophenone (19), benzoate (20, 29), benzaldehyde (21, 30) and naphthalenyl (25) substituents showed stronger anticancer activity against HepG2 cells than that of the etoposide. Interestingly, the p-tolyl analog (27) displayed the most potent inhibitory activity (IC50 = 0.56 μM) against HepG2 cells without affecting normal cells. Of the investigated tetrahydroisoquinoline-triazoles, the promising compounds 20 and 27 were selected for molecular docking against AKR1C3, which was identified to be a plausible target site.

    Background and Aims: Various additives are mixed with local anesthetic agents to increase the quality of block in regional anesthesia. We compared clonidine and dexmedetomidine as an adjunct to bupivacaine in supraclavicular brachial plexus block with respect to the onset and duration of sensory and motor block and duration of analgesia. Material and Methods: Sixty American Society of Anesthesiologists Grades I and II patients scheduled for various orthopedic surgeries of the upper limb under supraclavicular brachial plexus block were divided into two equal groups in a randomized, double-blind manner. Patients were assigned randomly to one of the two groups. In Group C (n = 30), 39 ml of 0.25% bupivacaine plus 1 ml (1 μg/kg) clonidine and in Group D (n = 30), 39 ml of 0.25% bupivacaine plus 1 ml (1 μg/kg) dexmedetomidine were given. The onset and duration of sensory and motor block, duration of analgesia, and quality of anesthesia were studied in both the groups. Results: There was no statistically significant difference in the onset of sensory and motor block in both the groups. The durations of sensory and motor block were 316.67 ± 45.21 and 372.67 ± 44.48 min, respectively, in Group C, whereas they were 502.67 ± 43.78 and 557.67 ± 38.83 min, respectively, in Group D. The duration of analgesia was 349.33 ± 42.91 min, significantly less in Group C compared to 525.33 ± 42.89 min in Group D (P < 0.001). The quality of anesthesia was significantly better in dexmedetomidine group compared to clonidine group (P < 0.001). Conclusion: The addition of dexmedetomidine prolongs the durations of sensory and motor block and duration of analgesia and improves the quality of anesthesia as compared with clonidine when injected with bupivacaine in supraclavicular brachial plexus block.

    In the treatment of adult patients with acute rhinosinusitis, it has been assumed that subjects over 65 years of age or living with children attending a day nursery, are at higher risk for infection with drug-resistant bacteria. However there are few reports which have discussed the relationship between those risk factors and adult patients with acute rhinosinusitis. I investigated the association between adult patients with acute rhinosinusitis living with children attending a day nursery and gender, ages, and frequency of detection of drug-resistant bacteria. From 2010 to 2012, a total of 598 adult patients with acute rhinosinusitis were enrolled. The majority of the study subjects were women, and the largest 10-year age group was 30-39 years. By sex, a greater proportion of the female subjects than the male subjects lived with children attending a day nursery. By age, the proportion of subjects who lived with children attending a day nursery was significantly higher in the 30-39-year age group than other age groups. Drug-resistant Streptococcus pneumoniae and ampicillin (ABPC)-resistant Haemophilus influenzae were detected at significantly higher rates in subjects with children attending a day nursery than in those without. There were no significant difference in drug-resistant bacteria detection between subjects over 65 years of age, and under 65 years. These findings suggested that living with children attending a day nursery is a risk factor and source of infection by drug-resistant organisms that may cause intra-familial infections of adult patients with acute rhinosinusitis. These results suggested we must ask adult patients with acute rhinosinusitis whether they are living with children attending a day nursery or not, when we plan their treatment strategy.

  19. Risk-adjusted melanoma skin cancer incidence rates in Whites (United States).

    2011-12-01

    The objective of this study was to obtain a better population-based measure of risk for melanoma skin cancer. A method has been previously proposed for estimating cancer incidence rates for data collected from the Surveillance, Epidemiology, and End Results (SEER) program. Unlike conventionally reported incidence rates in the USA, this method uses the first primary cancer and adjusts for population-based cancer prevalence to obtain a better measure of cancer risk. The study involves SEER data for white men and women. Conventional melanoma incidence rates overestimate risk for men, increasingly so from 3.3% in the age group of 30-39 years to 11.3% in the age group of 80 years and older. Overestimation in risk for women ranged from 3.3% in the age group of 30-39 years to 8.9% in the age group of 80 years and older. Overestimation of risk was more pronounced when both in-situ and malignant melanomas were considered. Increasing trends in conventional rates were slightly greater than trends in risk-adjusted incidence rates (RAIRs). In 2007, the estimated number of cases with malignant melanoma among the white population based on conventional cancer incidence rates is 37 636 (64 125 including in-situ cases) for men and 28 935 (49 361 including in-situ cases) for women. The estimated number of cases in the USA based on RAIRS is 34 652 [(7.9%); 55 413 (13.6%) including in-situ cases] for male and 27 178 [(6.1%); 44 467 (9.9%) including in-situ cases] for women. We concluded that RAIRs are a better measure of melanoma skin cancer risk and should be used for estimating the number of cancer patients in the USA.

    Background Practice recommendations for mammography screening were issued by the U.S. Preventive Services Task Force in 2009 and expansion of insurance coverage was provided under the Patient Protection and Affordable Care Act soon thereafter, yet the influence of these changes on screening practices in the United States is not known. Methods To determine changes in mammography screening and their associations with new practice recommendations and the Affordable Care Act, we examined patient-level data from 249,803 screening mammograms from January 1, 2008 through December 31, 2012 in a large community-based health system in the northwestern United States. Associations were determined by an intervention analysis of time-series data method. Results Among women screened, 64% were age 50-74 years; 84% self-identified as white race; 62% had commercial insurance; and 70% were seen in facilities located in metropolitan areas. Practice recommendations were associated with decreased screening volumes among women age <40 (-37.4 mammograms/month; -39.4% change; P<0.001), 40-49 (-106.0 mammograms/month; -11.2% change; P<0.001), and ≥75 (-54.7 mammograms/month; -10.0% change; P<0.001), but not women age 50-74. Implementation of the Affordable Care Act was associated with increased screening among women age 50-74 (+184.3 mammograms/month; +7.2% change; P=0.001), but not women <40 or ≥75; increases for age 40-49 were of borderline statistical significance (+56.9 mammograms/month; +6% change; P=0.06). Practice recommendations were also associated with decreased screening for women with commercial insurance, while the Affordable Care Act was associated with increased screening for women with Medicare, Medicaid, or other noncommercial sources of payment. Conclusions Mammography screening volumes in a large community health system decreased among women age <50 and ≥75 in association with new U.S. Preventive Services Task Force practice recommendations, while insurance coverage

    Three diterpenoids, 1-oxomicrostegiol (1), viroxocin (2), viridoquinone (3), were isolated from the roots of Salvia viridis L. cvar. Blue Jeans. Five known diterpenoids, microstegiol (4), 7α-acetoxy-14-hydroxy-8,13-abietadiene-11,12-dione (5; 7-O-acetylhorminone tautomer), 7α,14-dihydroxy-8,13-abietadiene-11,12-dione (6; horminone tautomer), ferruginol and salvinolonyl 12-methyl ether (7) were also found in the roots together with 1-docosyl ferulate (8), and a mixture of 2-(4'-alkoxyphenyl) ethyl alkanoates (9). Two lupane triterpenoids, 2α-acetoxy-lup-20(29)-en-3β-ol (10), and 3β-acetoxy-lup-20(29)-en-2α-ol (11) were found in the aerial parts together with known compounds, lup-20(29)-ene-2α,3β-diol (12), ursolic acid, oleanolic acid, β-sitosterol and β-sitosterol glucoside. A known phenylpropanoid, trans-verbascoside (or acteoside; 13), was the main constituent in the polar fraction of the aerial part, and it is now reported in the genus Salvia for the first time. Other polyphenolic compounds were cis-verbascoside (14), leucosceptoside A (15), martynoside (16), caffeic acid, 6-O-caffeoyl-glucose (18), rosmarinic acid, salidroside, luteolin-7-O-α-rhamnopyranosyl-(1→6)-β-galactopyranoside, luteolin-7-O-β-galactopyranoside, luteolin-7-O-α-rhamnopyranosyl-(1→6)-β-glucopyranoside, luteolin-7-O-β-glucopyranoside, and apigenin-7-O-β-glucopyranoside. The structures were determined by 1D-, 2D-NMR and HR-ESI-MS techniques. Compounds 6, 10, ferruginol, ursolic acid and oleanolic acid exhibited antibacterial activity against Enterococcus faecalis (ATCC 775) with MIC 50 μM, 25 μM, 50 μM, 12.5 μM, 12.5 μM respectively. Ferruginol, ursolic acid and oleanolic acid were also active against Staphylococcus aureus (ATCC 6571), and Bacillus cereus (ATCC 2599) with MIC 12.5-50 μM. 4 was also active against S.aureus (ATCC 6571) with MIC 50 μM. These values are consistent with previous studies on the antimicrobial activity of Salvia diterpenoids.

    The purpose of this investigation was to evaluate the acute effects of missing a meal on alertness. The participants were ten university students between 20-29 years old, five females and five males. Participants were chosen on the basis of their good sleep and eating practices. Measurements were collected during an eight hour period starting at 8.00 AM on four separate days. During the test period, participants carried out their normal study activities while on separate days receiving either just breakfast, just lunch, both lunch and breakfast, or no meal at all. During the test period, EEG was monitored continuously while subjective ratings of performance and tiredness were collected every half-hour. The results showed that while there were neither physiological nor subjective indications of tiredness which could be attributed to meal consumption, subjective feelings of lack of energy and motivation was significantly more pronounced at the end of the workday when missing a meal or two.

    The interrelations of circannual rhythms of the functional state of pineal gland, hypophysis, adrenal cortex, thymus in healthy women and men from 20 to 79 years were studied. Fluctuations of melatonin, ACTH, cortisol and thymic serum factor, which were exchanged in aging (the season peaks of hormones and its acrophase) were found in blood of healthy 20-29 years old people. The changes of rhythmicity of indices were in male earlier (pineal gland and hypophysis over 30 years, thymus and adrenal cortex over 40 years) and more impressive than in women. The aging changes of pineal gland function's rhythm in healthy subjects have important role for changes of interrelations of circannual rhythms hypophysis, adrenal cortex and thymus.

    Ageism has been found to exist throughout a wide variety of societal institutions. Whether it also exists in social networking sites has not been previously considered. To explore this possibility, we conducted a content analysis of each publicly accessible Facebook group that concentrated on older individuals. The site "Descriptions" of the 84 groups, with a total of 25,489 members, were analyzed. The mean age category of the group creators was 20-29; all were younger than 60 years. Consistent with our hypothesis, the Descriptions of all but one of these groups focused on negative age stereotypes. Among these Descriptions, 74% excoriated older individuals, 27% infantilized them, and 37% advocated banning them from public activities, such as shopping. Facebook has the potential to break down barriers between generations; in practice, it may have erected new ones.

    From June 20-29, 1995, more than a thousand college and university students from across North America tested their solar cars and strategies against the environment in Sunrayce 95. The 1,250-mile race, from Indiana to Colorado, is the third in a series of collegiate solar-car races across the United States. The tradition began in 1990 with the GM Sunrayce USA from Florida to Michigan. In 1993, the tradition continued as 34 solar cars raced more than 1,100 miles from Texas to Minnesota in Sunrayce 93. The U.S. Department of Energy, General Motors Corporation, and other organizations teamed together in a unique partnership between government and industry to sponsor Sunrayce 95. Their goal was to make learning exciting and relevant to today`s concerns and to demonstrate that brain power is more important than horsepower.

    White tail disease (WTD) kills prawn larvae and causes drastic losses to the freshwater prawn (Macrobrachium rosenbergii) industry. The main causative agent of WTD is Macrobrachium rosenbergii nodavirus (MrNV). The N-terminal end of the MrNV capsid protein is very rich in positively charged amino acids and is postulated to interact with RNA molecules. N-terminal and internal deletion mutagenesis revealed that the RNA-binding region is located at positions 20-29, where 80 % of amino acids are positively charged. Substitution of all these positively charged residues with alanine abolished the RNA binding. Mutants without the RNA-binding region still assembled into virus-like particles, suggesting that this region is not a part of the capsid assembly domain. This paper is, to the best of our knowledge, the first to report the specific RNA-binding region of MrNV capsid protein. PMID:24878641

    Despite a proliferation of research on disordered eating in female athletes, few studies have included male athletes. The purpose of this study was to determine which of five personality and psychological variables of interest (i.e., perfectionism, self-esteem, optimism, reasons for exercise, and appearance orientation) best predicted eating disorder status (i.e., symptomatic or asymptomatic) in male athletes. Two hundred three male athletes (Mage=20.29, SD=1.64) from three National Collegiate Athletic Association (NCAA) Division I institutions participated. More athletes were asymptomatic (80.8%) than symptomatic (19.2%). None of the variables significantly predicted symptomatic status. These findings contrast the literature on predictors of disordered eating symptomatology among female athletes, and suggest the need for further research to identify other potential predictors of eating disturbance among male athletes.

    In this article, two structures are proposed for all-optical AND, XOR, and OR logic gates based on nonlinear photonic crystals. The proposed structures include a Y-junction and ring resonator-based limiters. Two different structures are designed as the limiter in order to produce AND-XOR and AND-OR logic gates. Nonlinear rods of proposed structure have been used in order to create the frequency shift for different values of input power. Finite difference time domain method has been utilized to simulate the performance of proposed logic gates. Simulation results show that the smallest ON-OFF logic-level contrast ratio for the structures proposed for AND-XOR and AND-OR logic gates are 20.29 dB and 16.7 dB, respectively.

    The basic behavioral activity of nonlinear rats was evaluated from the sum of crossed peripheral and central squares and peripheral and central rearing postures in the open fi eld test. This index was low (<20 episodes), intermediate (20-29 episodes), or high (>30 episodes). Male rats with high score of orientation and exploratory activity were characterized by higher indexes of total heart rate variability than rats with low or intermediate activity. Specimens with a greater contribution of VLF waves into the total power spectrum of heart rate variability were shown to dominate among the rats with high behavioral activity. Our results are consistent with the notions of a suprasegmental nature of VLF waves.

    We estimate the income-related inequality in Sweden with respect to life-years and quality-adjusted life-years (QALYs). We use a large data set from Sweden with over 40,000 individuals followed up for 10-16 years, to estimate the survival and quality-adjusted survival in different income groups. For both life-years and QALYs, we discover inequalities in health favouring the higher income groups. For men (women) in the youngest age-group (20-29 years), the number of QALYs is 43.7 (45.7) in the lowest income decile and 47.2 (49.0) in the highest income decile.

    The present work evaluated the chemical composition and antiulcerogenic potential of the crude extract, fractions and pure compounds isolated of roots barks from Maytenus robusta Reiss, using different pharmacological models in mice. 3,12-Dioxofriedelane (1) and 11-hydroxylup-20 (29)-en-3-one (2) were isolated from the n-hexane fraction, and mayteine (3) and 3,7-dioxofriedelane (4) from the dichloromethane fraction. The crude extract (50, 259, 500 mg/kg), all the fractions (250 mg/kg) and cimetidine (100 mg/kg) significantly reduced the lesion index, total lesion area, and percentage of lesions, in comparison with the control group (p < 0.05), by ethanol and NSAID-induced ulcer models. All the isolated compounds also presented significant pharmacological effects at 30 mg/kg. These results show that the root bark of M. robusta may be a promising source of molecules with applicability in the treatment of gastric disorders. PMID:27319126

    Media reports of interviews with 93 adults transracially adopted as children were content analyzed (percentage agreement = 80%-100%, Cohen's kappas = .61-1.00). Most interviews (63%-88%) involved adoptees who were African American or biracial; in college, graduate school, or employed in professional or managerial occupations; 20-29 years old; and raised in the East or Midwest, with siblings who were the adoptive parents' biological children, other transracial adoptees, or a combination. Forty substantive themes were categorized as adoptive family relationships, direct outcomes, ethnicity and ethnic identification, general adoption issues, and racism experiences. Limitations of media-collected data and the influence of media reports on public opinion and public policies emphasize the importance of scientifically studying controversial phenomena such as transracial adoption.

    This report is a retrospective study of the epidemiology of scorpion sting cases recorded from 2007 to 2013 in the State of Ceará, Northeastern Brazil. Data were collected from the Injury Notification Information System database of the Health Department of Ceará. A total of 11,134 cases were studied and distributed across all the months of the studied period and they occurred mainly in urban areas. Victims were predominantly 20-29 years-old women. Most victims were bitten on the hand; and received medical assistance within 1-3 hours after being bitten. Cases were mostly classified as mild and progressed to cure. Scorpion envenomation in Ceará is an environmental public health problem that needs to be monitored and controlled throughout the year. PMID:27007558

    White tail disease (WTD) kills prawn larvae and causes drastic losses to the freshwater prawn (Macrobrachium rosenbergii) industry. The main causative agent of WTD is Macrobrachium rosenbergii nodavirus (MrNV). The N-terminal end of the MrNV capsid protein is very rich in positively charged amino acids and is postulated to interact with RNA molecules. N-terminal and internal deletion mutagenesis revealed that the RNA-binding region is located at positions 20-29, where 80 % of amino acids are positively charged. Substitution of all these positively charged residues with alanine abolished the RNA binding. Mutants without the RNA-binding region still assembled into virus-like particles, suggesting that this region is not a part of the capsid assembly domain. This paper is, to the best of our knowledge, the first to report the specific RNA-binding region of MrNV capsid protein.

    In this study, we propose a simple method for obtaining the thermal conductivity of silicon nanowires (SiNWs) embedded on a thermoelectric platform. The approximation of the heat flux in SiNWs with temperature differences enables the determination of thermal conductivity. Using this method, the thermal conductivities of our n- and p-type SiNWs are found to be 18.06  ±  0.12 and 20.29  ±  0.77 W m-1 · K-1, respectively. The atomic weight of arsenic ions in the n-type SiNWs is responsible for a lower thermal conductivity than that of boron ions in the p-type SiNWs. Our results demonstrate that this simple method is capable of measuring the thermal conductivity of thermoelectric nanomaterials embedded on thermoelectric devices.

    A novel lupane-triterpene glycoside, called wujiapioside B (1), was isolated from the leaves of Acanthopanax gracilistylus (Araliaceae) together with three known lupane-triterpene glycosides, acankoreoside C (2), acantrifoside A (3) and 3-epibetulinic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (4). Based on spectroscopic data, the chemical structure of 1 was determined as 3alpha,23-dihydroxy-lup-20(29)-en-28-oic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester. Compounds 2-3 were obtained for the first time from this plant and compound 4 has not been isolated from Acanthopanax genus yet. PMID:12372869

    The genetic effects on individual differences in reading development were examined using genome-wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, n = 2,942), the GCTA-based heritability of reading fluency was ~20%-29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (r = 0.69) is largely driven by genetic stability (genetic r = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene-environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (n = 1,066-1,409). PMID:24392801

    1997-03-01

    Slipping on ice or snow during winter caused 3.5 injuries per 1000 inhabitants per year in the Umeå health district; the injury rate was highest among the elderly. Most injured were elderly women, but also many young men in the age group 20-29 years were injured. Half of all injuries were fractures; for women 50 years and over two-thirds were fractures, mostly of an upper extremity. The 'cost' of medical care of these slipping injuries was almost the same as the 'cost' of all traffic injuries in the area during the same time. Injury reducing measures, such as more effective snow clearing, sand and salt spreading in strategic areas, better slip preventive aids on shoes, and 'padding' of older women, would reduce the injuries and their consequences.

    Mechanisms of altered pulmonary gas exchange during water immersion were studied in 12 normal males: 6 young (aged 20-29) and 6 older (aged 40-45). It is concluded that, in young subjects with closing volume (CV) less than expiratory reserve volume (ERV), gas exchange was enhanced during immersion, because normal ventilation-perfusion relations were preserved, and by mass balance, the ventilation/O2 uptake changes elevated arterial P(O2). In older males with CV greater than ERV and 52 percent of tidal volume below CV, immersion-induced airways closure during tidal breathing was associated with minimally increased shunt that did not significantly impair gas exchange. It is suggested that airways closure of this degree is of little importance to gas exchange.

    Objective. The aim of this study was to evaluate the effect of maternal age on prenatal and obstetric outcome in multiparaous women. Materials and Methods. 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.

    Typhoid vaccination is recommended in the United States before travel to countries where typhoid fever is endemic, though little information is available on its effectiveness in travelers. We estimated typhoid vaccination effectiveness (VE) by comparing vaccination status in cases of typhoid fever and paratyphoid fever (Salmonella Paratyphi A infection, against which typhoid vaccine offers no protection) reported in the United States. We included travelers to Southern Asia and excluded persons <2 years old and cases in which vaccination status was not reported. From 2008 through 2011, 744 eligible cases (602 typhoid, 142 paratyphoid A) were reported to CDC. Typhoid vaccination was reported for 5% (29/602) of typhoid patients and for 20% (29/142) of paratyphoid A patients. Estimated VE was 80% (95% confidence interval, 66–89%). Because of missing data, we could not estimate VE for specific vaccines. We demonstrated moderate effectiveness of typhoid vaccination in US travelers, supporting vaccination recommendations.

    The methanolic extract of seeds of the tropical fruit camu-camu was screened for its anti-inflammatory activity in carrageenan-induced paw edema model mice. The extract significantly suppressed both the formation of edema in mice by oral administration and the release of nitric oxide from macrophage-derived RAW 264.7 cells in vitro. Based on the results of a spectroscopic analysis, the active compound was identified by in vivo bioassay-guided fractionation to be 3β-hydroxy-lup-20(29)-en-28-oic acid, betulinic acid, known as an anti-inflammatory triterpenoid. These findings suggest that camu-camu seed extract is a potentially useful material as a source of betulinic acid and as a functional food for prevention of immune-related diseases. PMID:21512298

    The mutagenic and antimutagenic activities of triterpene betulinic acid {3b-3-hydroxy-lup-20(29)-en-28-oic} isolated from the roots of Scoparia dulcis (Scrophulariaceae) were analyzed using the somatic mutation and recombination test (SMART) in the wings of Drosophila melanogaster. The mutagenic potential of betulinic acid was evaluated at 3 different concentrations (1.64, 3.28, and 6.57 mM). Antimutagenic activity evaluation was performed by co-treatment trials in which the flies received betulinic acid at 3 different concentrations in addition to 10 mM pro-mutagenic urethane. The results demonstrated that betulinic acid was not capable of causing DNA damage. However, the frequency of small single spots, large spots, and twin spots was significantly reduced. In the high bioactivation cross, betulinic acid was significantly active and exerted enhanced antimutagenic activity, possibly as a desmutagen. PMID:26345907

    Crude extracts and VLC fractions from the stem bark of Barringtonia acutangula (L.) Gaertn (Fam. Lecythidaceae) were screened for their antimicrobial activities against two Gram-positive bacteria, two Gram-negative bacteria and two fungi using a microdilution titre assay. Among the crude extracts, petroleum ether extract showed good activity against all test organisms. The VLC fraction PE 16 was found to be very effective against Bacillus subtilis (MIC=25 microg/ml) and Aspergillus niger (MIC=12.5 microg/ml). The activities were compared to standard antibiotics-kanamycin and fluconazole. The major compound from PE16 was identified as 12, 20(29)-lupadien-3-ol by NMR spectroscopy. PMID:16114086

    We performed a clinico-statistical study of the maxillofacial fracture due to sports during the period of 15 years between 1977 and 1991. Eighty-nine patients were seen with injuries resulting from 21 different sports. The incidence of the fracture was most common in rugby, followed by ski, baseball and soccer. Males were shown to be more prone to maxillofacial fracture than females (5.4:1) and the highest incidence of injuries involved the 20-29 age group followed by the 10-19 age group. The major parts of the fracture were the mandible and the alveolar process. Conservative therapy such as maxillomandibular fixation was usually performed and the clinical course was good. It was suggested that the prevention of the sports-related fracture and the time of returning to sports after the fracture will require further study.

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

    The dengue viruses (DENV) are endemic in the tropical and sub-tropical countries and cause the most common arthropod-borne viral disease in humans. Travelers visiting endemic areas may both acquire and spread DENV infections, and this is the reason why prevention of mosquito bites is of crucial importance. Dengue fever (DF) has become the most common cause for tropical fever in Swedish tourists. Swedish data from 1995 to 2010 show that the number of DF cases has increased since the beginning of 2000; partly due to improved diagnostics based on IgM detection, and partly due to an increase in the number of tourists traveling to, and between, endemic areas. Young adults aged 20-29 are mostly affected, and epidemiological data indicate increased incidence rates from 2008 onwards. Our data pose a call for attention when traveling to DENV endemic areas as well as an increased awareness among physicians when treating returning travelers.

    Ciguatera poisoning is endemic in many tropical and subtropical countries. We conducted a retrospective study of admissions to two hospitals on the islands of Vanuatu in the southwestern Pacific region. We estimated the annual hospital admission rate for fish poisoning to be 65 (95% confidence interval [CI] = 55-75)/100,000 population on the island of Santo and 29 (95% CI = 19-43)/100,000 population on the island of Ambae. Hospital admission was more common in males 20-29 years old. Death was a rare complication. In the face of increases in both tourism and in the global trade in tropical and exotic fish, physicians in both endemic and non-endemic areas should be familiar with the epidemiology and clinical features of this important condition.

    The purpose of this study was to evaluate the daily vegetable and fruit intake status of Korean adults and to examine the relationship of vegetable and fruit intake with bone metabolism. The vegetable and fruit intake of 542 healthy male and female adults was analyzed. Then, by selecting 51 targets from the subjects, the relation of vegetable and fruit intake with serum calcium, osteocalcin and deoxypyridinoline (DPD) excretion in urine was examined. The total vegetable intake per day was 397.7 g and 333.5 g by men and women respectively for the age group of 20-29, 366.9 g and 309.2 g respectively for the age group of 30-49, 378.4 g and 325.9 g respectively for the age group of 50-64. Of vegetable varieties, leafy and stem vegetables displayed the highest intake. The order of major intake items of vegetables and fruits was found to be Chinese cabbage kimchi, onion, radish, cucumber, and welsh onion for the age group of 20-29, watermelon, Chinese cabbage kimchi, peach, potato, and onion for the age group of 30-49 and watermelon, Chinese cabbage kimchi, tomato, potato, and peach for the age group of 50-64. Of 51 targets, β-carotene intake displayed a significantly negative correlation with serum osteocalcin. While caloric intake as well as protein, carbohydrate, calcium, phosphorous, zinc and total food intake displayed a significantly negative correlation with DPD excretion in urine, tuber vegetable intake displayed a significantly positive correlation with DPD excretion in urine. In the future, a study will be necessary to accurately explain the relevance of vegetable and fruit intake with bone mineral density and bone metabolism. Also, efforts will be required to increase vegetable and fruit intake. PMID:21103089

    This article summarizes a 1995 report to the US Congress from a working groups at the Department of Health and Human Services. This paper describes trends in nonmarital childbearing by age, race, education, residence, and parents' background. Several explanations are provided for the observed changes in nonmarital fertility. Pregnancy outcomes are described. Other issues are discussed pertaining to subsequent fertility, public assistance, and a comparison with international trends. It is argued that a narrow view of the problem obscures the key issues. Although 66% of nonmarital childbearing occurs among women aged older than 20 years, most research and programs target adolescent nonmarital childbearing. In 1993 there were 1.2 million infants born to unmarried women, a substantial increase over several decades. The increase was highest during the 1970s. Trends stabilized in the 1990s. The rate of nonmarital childbearing was the highest among women aged 20-24 years in 1993, followed closely by women aged 18-19 years. Nonmarital childbearing included 30% of births to teenagers, 54% to women aged in their 20s, and 16% to women aged 30 years and older. In 1970 teenage nonmarital childbearing comprised the largest proportion of nonmarital births (50%); 42% of births were to women aged 20-29 years. Hispanic women were found to be more likely to have nonmarital births. Over 60% of nonmarital births were to White women (42% to White women aged 20-29 years). Declines in marriage explained most of the growth during 1968-84 for Black women; thereafter increases in the rate of nonmarital births and the proportion of women married accounted for the Black nonmarital birth ratio. For White women during 1968-93, the deciding factors have been the same factors as for Blacks after 1984. Other trends include the lesser likelihood of both married and unmarried women to terminate pregnancies. About 80% of children receiving public assistance lived in families headed by never married

Abnormalities included disc degeneration, disc herniation, pars lesions (fracture or stress reaction), and facet joint arthropathy. Results Five players (15.2%) had a normal MRI examination and 28 (84.8%) had an abnormal examination. Nine players showed pars lesions (10 lesions; one at two levels) predominately at the L5 level (9/10, L5; 1/10, L4). Three of the 10 lesions were complete fractures; two showed grade 1 and one grade 2 spondylolisthesis, both of which resulted in moderate narrowing of the L5 exit foramen. There were two acute and five chronic stress reactions of the pars. Twenty three patients showed signs of early facet arthropathy occurring at L5/S1 (15/29 joints) and L4/5 (12/29 joints). These were classified as mild degeneration (20/29) and moderate degeneration (9/29), with 20/29 showing sclerosis and 24/29 showing hypertrophy of the facet joint. Synovial cysts were identified in 14 of the 29 joints. Thirteen players showed disc desiccation and disc bulging (mild in 13; moderate in two) most often at L4/5 and L5/S1 levels (12 of 15 discs). Conclusions Abnormalities were frequent, predominately in the lower lumbar spine, almost exclusively at L4/5 and L5/S1 levels. Pars injuries and facet joint arthroses were relatively common.

    Purpose: The effect of transient tumor expansion after conventionally fractionated stereotactic radiation therapy (SRT) on the symptomatic outcomes is not well-known. Methods and Materials: This study enrolled 201 consecutive patients who received SRT for vestibular schwannoma. A conventional fractionation schedule was applied in 194 patients (97%), and 142 (71%) received a total dose of 50 Gy. The median follow-up time was 72 months. Results: The maximum diameter was 9 mm or less in 13 patients, 10-19 mm in 79 patients, 20-29 mm in 87 patients, and 30 mm or greater in 22 patients. At presentation, tumor size of 20 mm or greater was significantly associated with loss of serviceable hearing and trigeminal neuropathy. After SRT, tumor expansion was observed in 42 patients (21%). By tumor size, tumor expansion was observed in 0%, 11.4%, 25.6%, and 50% of patients with tumors of 9 mm or less, 10-19 mm, 20-29 mm, and 30 mm or greater, respectively, in diameter. The tumor expansion was significantly associated with an increased risk of hydrocephalus requiring shunt placement (P=.004), loss of serviceable hearing (P=.0064), and worsening of facial (P<.0001) and trigeminal nerve (P<.0001) functions. Spontaneous tumor shrinkage was observed in 29 of those 42 patients, mostly within 2 years after the expansion, and the majority of the worsened symptoms except for hearing resolved once the tumor had shrunk. As a result, salvage surgical resection for symptomatic relief was required in only 5% of patients. Conclusions: Fractionated SRT could be safely applied even for medium- to large-sized ({>=}20 mm) tumors. However, greater knowledge of the risks and consequences, including transient symptomatic worsening, and the time span of expansion will be required for the follow-up of patients after SRT to avoid unnecessary surgical intervention.

    The study of somatotypes has important significance for medical and physical anthropology as well as sports science. The aim of this study was to understand the somatotype components of the Han population in Xi'an and compare the somatotypes of the Han and five other nationalities in China. The study sample consisted of 429 people of Han nationality (207 males, 222 females) from Xi'an, China, aged ≥20 years old. The Heath-Carter anthropometric method was employed. We evaluated the differences in age and sex by one-way ANOVA and t test. A comparison of somatotypes between the Han and other nationalities was made using the U test. The results showed that the male and female samples all could be classified as having a mesomorphic endomorph profile. The difference in endomorphy was strongest between sexes in all age groups (P < 0.01). There were prominent differences in mesomorphy and ectomorphy between males and females in the 50-59- and ≥60-year-old age groups. In females, the differences in somatotype components appeared to be distinguished between ages (P < 0.01 or P < 0.05). However, in males, there were prominent differences in somatotype components between the 20-29 year olds and all other age groups (P < 0.01 or P < 0.05) except for between those 20-29 and ≥60 years old in endomorphy. Compared with the other five nationalities, there were prominent differences in somatotype components between males and females. These results suggest that the somatotype of the Han population in Xi'an, China, has a predominantly mesomorphic endomorph profile. The endomorphic component shows distinct differences between ages and genders, respectively. Additionally, there are distinct differences in the somatotype components between Xi'an Han and five other nationalities in China in males and females. PMID:25940679

    Approximately 5,000 of 6 million annual visitors of the Oktoberfest in Munich have to undergo medical treatment. Patients with alcohol intoxication without trauma or further complications are all treated in a specialized medical camp. We studied these patients in order to identify risk factors and to assess the relevance of the Glasgow Coma Score (GCS) and of ethanol blood concentrations for patient management. In 2004 totally 405 patients suffering from ethanol intoxication without trauma were treated in the medical camp. A complete set of the following data was obtained from all 405 patients: GCS, ethanol blood concentration, age, sex, blood pressure (mean, systolic and diastolic), body temperature, heart rate, blood sugar, GOT, gamma-GT, and CK. A multivariate logistic regression model was applied to identify risk factors predicting patients at increased risk of hospitalization. Low GCS (< or =8 vs. >8, OR: 4.18, CI: 1.96-8.65) low age (20-29 vs. > or =30 years, OR: 2.35, CI: 1.05-5.65) and male gender (male vs. female, OR: 3.58, CI: 1.36-9.34) independently predicted patients that had to be hospitalized. All other parameters including ethanol blood concentrations were not explanatory. Patients with GCS < or = 8 (n = 66) had a lower median blood pressure (P = 0.0312) and showed a smaller increase in blood pressure during the observation period compared to patients with GCS > 8 (P < 0.001), suggesting that this subgroup may require longer recovery periods. Men aged 20-29 years were at highest risk for hospital admission. Increased risk could not be explained by higher ethanol blood concentrations in this subgroup. Importantly, GCS < 6 does not justify endotracheal intubation in ethanol intoxicated patients, when further complications, such as trauma, can be excluded.

    Background & objectives: Studies conducted to assess the prevalence of cardiovascular (CV) risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. Methods: In a cross-sectional survey, 2227 subjects aged ≥ 20 yr were studied from April 2008 to June 2009 in Urban Chandigarh, a north Indian city. Demographic history, anthropometry and blood pressure were assessed. Fasting, and 2 h capillary plasma glucose after 75 g glucose load, HDL-C and triglycerides were estimated. Results: The most prevalent cardiovascular risk factors in the age group of 20-29 yr was sedentary lifestyle (63%), while from fourth decade and onwards, it was overweight/obesity (59-85%). The second most common prevalent cardiovascular risk factor in the age group of 20-29 yr was overweight/obesity, in 30-49 yr sedentary lifestyle, in 50-69 yr hypertension and in subjects ≥70 yr, it was hypertriglyceridaemia. The prevalence of overweight/obesity, hypertension, dysglycaemia and smoking was almost double in subjects in the fourth decade of life, as compared to those in the third decade of life. The prevalence of CV risk factors significantly increased with age irrespective of gender and prevalence of low HDL-C was significantly more common in women as compared to men. Interpretation & conclusions: Sedentary lifestyle, obesity and low HDL-C are the most prevalent CV risk factors in subjects in the third and fourth decade of life in this north Indian population and clustering of these cardiovascular risk factors increases with advancing age. Strategies need to be formulated to target this population to prevent the epidemic of cardiovascular disease. PMID:24718400

    A techno-economic analysis was conducted for a simplified lignocellulosic ethanol production process developed and proven by the University of Florida at laboratory, pilot, and demonstration scales. Data obtained from all three scales of development were used with Aspen Plus to create models for an experimentally-proven base-case and 5 hypothetical scenarios. The model input parameters that differed among the hypothetical scenarios were fermentation time, enzyme loading, enzymatic conversion, solids loading, and overall process yield. The minimum ethanol selling price (MESP) varied between 50.38 and 62.72 US cents/L. The feedstock and the capital cost were the main contributors to the production cost, comprising between 23-28% and 40-49% of the MESP, respectively. A sensitivity analysis showed that overall ethanol yield had the greatest effect on the MESP. These findings suggest that future efforts to increase the economic feasibility of a cellulosic ethanol process should focus on optimization for highest ethanol yield.

    Biofouling control is considered as a major challenge in operating membrane systems. A lab-scale RO system was setup at a local water reclamation plant to study the feasibility of using biofiltration as a pretreatment process to control the biofouling. The biological activity in the RO system (feed, product, reject streams) was tested using the standard serial dilution plating technique. Operational parameters such as differential pressure (DP) and permeate flowrate of the system were also monitored. Effects of biofilter on AOC and DOC removals were investigated. Biofiltration was found to be a viable way of assimilable organic carbon (AOC) and dissolved organic carbon (DOC) removals, with removal efficiencies of 40-49% and 35-45% at an empty bed contact time (EBCT) of 30 min. It was also found that using the biofiltration as a pretreatment reduced the rate of biofouling. It took only about 72 h for biofouling to have a significant impact on the performance of the RO membrane, when the system was operated without using biofiltration as pretreatment. There was, however, a five times increase in operational length to more than 300 h when biofiltration was used. This study presented the suitability of the biofilter as an economical and simple way of biofouling control for RO membrane.

    We sought to identify risk factors for type 2 diabetes (T2D) in Jammu and Kashmir populations, India. A total of 424 diabetic and 226 non-diabetic subjects from Jammu, and 161 diabetic and 100 non-diabetic subjects from Kashmir were screened for various parameters including fasting blood glucose level, 2 hour glucose level, urea, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein (VLDL-C), uric acid, systolic and diastolic blood pressure level. We found that subjects aged 40-49 years had the highest rate of diabetes, with family income playing not much of a role. Kashmiri migrants or populations with rapid cultural, environmental, social or lifestyle change along with reduced physical activity, obesity and unhealthy lifestyle (smoking and alcohol consumption) were found to have higher rates of diabetes. High blood glucose, triglycerides and low HDL-C levels were found to be contributing to disease outcome. High blood pressure also contributed to a higher risk of developing T2D. Our study supports earlier reports confirming the contribution of comfortable life style, Western dietary habits and rapid life style change along with many other factors to the prevalence of diabetes. This may contribute to the epidemic proportion of diabetes in Jammu and Kashmir. Early diagnosis and routine screening for undiagnosed diabetes in obese subjects and subjects with parental diabetes history is expected to decrease the burden of chronic diabetic complications worldwide.

  4. The educational gradient in marriage: a comparison of 25 European countries.

    Previous research has suggested that a new marriage gradient has emerged in the United States, with marriage becoming increasingly the privilege of the better-educated. This article examines whether this is true for Europe and explores differences in the marriage gradient among 25 European countries, using multilevel models. The focus is on the chances of living in a marital (or cohabiting) union during midlife (ages 40-49). Multilevel analyses show that the direction and strength of the gradient depend on the societal context. In countries where gender roles are traditional, better-educated women are less likely to be married than less-educated women; in gender-egalitarian countries, better-educated women are more likely to be married. For men, the educational effect on marriage is absent in traditional countries but becomes positive as gender roles become more equal. Inequality in a society also modifies the gradient: if the degree of economic inequality between educational groups in a society is strong, better-educated men are more likely to be married than less-educated men. In general, the results suggest that there may be an accumulation of social and economic disadvantages for the less well educated in more-developed countries.

    The objective of this study was to study the effect of early pelvic floor re-education on the degree and duration of incontinence and to evaluate the results of radical retropubic prostatectomy (RRP) performed in a non-teaching hospital. This is a non-randomised study. From March 2000 to November 2003, 57 consecutive men, who underwent RRP for localized prostate cancer, participated in a pelvic floor re-educating program. Continence was defined as a loss of no more than 2-g urine on the 24-h pad test and no use of pads. The 24-h pad test was performed once in every 4 weeks until the patient indicated that he was continent. Diurnal and nocturnal continence was achieved after 1, 2, 3, 6 and 12 months post catheter removal in 40, 49, 70, 86 and 88% of all men, respectively. Comparison of our results with current literature suggest that the time period towards continence after a RRP can be shortened relevantly if pelvic floor re-education is started directly after catheter removal.

    We have analyzed the frequency of premutations of the FRM1 gene in 3000 X chromosomes of 1000 male and 1000 female consecutive newborn Guthrie blood spots in an unlinked, anonymous survey. The CGG repeat sizes were calculated by measuring the length of products of the PCR reaction based on the molecular size of labeled markers in a denaturing sequencing gel assay. For consistent PCR amplification a DNA microextraction was necessary, including a phenol/chloroform series. In our population, the CGG repeat ranged from 9-106 but 96% of alleles had fewer than 40 repeats. The most frequent allele was a repeat of 28. Approximately 2.7% of alleles had CGG repeats ranging from 40-49 and 0.36% of alleles had repeats ranging from 50-59. The frequency of alleles {ge}60 repeats in the Manitoba population is approximately 0.18%. The use of Guthrie blood spots for population screening of fra(X) premutations is not recommended. The necessity of a phenol/chloroform DNA microextraction is tedious and time consuming. The low yield of DNA (-250 ng) does not allow for re-analysis by Southern blot of apparently homozygous females and may result in an underestimate of premutation carrier status.

    AIM: To investigate the features of abdominal crush injuries resulting from an earthquake using multidetector computed tomography (MDCT). METHODS: Fifty-one survivors with abdominal crush injuries due to the 2008 Sichuan earthquake underwent emergency non-enhanced scans with 16-row MDCT. Data were reviewed focusing on anatomic regions including lumbar vertebrae, abdominal wall soft tissue, retroperitoneum and intraperitoneal space; and types of traumatic lesions. RESULTS: Fractures of lumbar vertebrae and abdominal wall soft tissue injuries were more common than retro- and intraperitoneal injuries (P < 0.05). With regard to the 49 lumbar vertebral fractures in 24 patients, these occurred predominantly in the transverse process (P < 0.05), and 66.67% of patients (16/24) had fractures of multiple vertebrae, predominantly two vertebrae in 62.5% of patients (10/16), mainly in L1-3 vertebrae in 81.63% of the vertebrae (40/49). Retroperitoneal injuries occurred more frequently than intraperitoneal injuries (P < 0.05), and renal and liver injuries were most often seen in the retroperitoneum and in the intraperitoneal space, respectively (all P < 0.05). CONCLUSION: Transverse process fractures in two vertebrae among L1-3 vertebrae, injury of abdominal wall soft tissue, and renal injury might be features of earthquake-related crush abdominal injury.

    Objectives. To evaluate the efficacy of trimetazidine dihydrochloride as a treatment for chronic tinnitus. Methods. A total of 97 chronic tinnitus patients were evaluated in this randomized, prospective, double-blind, placebo-controlled trial. After assessing for eligibility, 82 patients were randomly assigned into placebo or trimetazidine groups according to the medication. The trimetazidine group received 20×3 mg/day per oral trimetazidine dihydrochloride and the placebo group received 20×3 mg/day per oral placebo for 3 months. Tinnitus handicap inventory (THI), visual analogue scale (VAS) questionnaires and audiometric results were used to determine the effectiveness of trimetazidine treatment. Results. The study group comprised 82 tinnitus subjects, 42 (51%) of whom received trimetazidine dihydrochloride and 40 (49%) who received placebo. There was no significant difference between placebo and trimetazidine groups in THI grade and VAS (both pre- and posttreatment scores) (P>0.05) and no significant improvement was observed in subjective loudness score in either group (P>0.05). Additionally there was no significant difference between groups in pre- and posttreatment pure tone hearing thresholds at all measured frequencies (P>0.05). Conclusion. Trimetazidine dihydrochloride therapy was ineffective for relieving chronic tinnitus. PMID:27230273

    Numerous studies and meta-analyses have shown that hormone replacement therapy (HRT) for menopausal symptoms increases the risk of developing breast cancer, estimated to be 2.3% for each year of use. The influence of different oestrogen-progestin regimens has still not been fully evaluated. Using longitudinal data from the population-based prescription database of the county of North Jutland, Denmark, and the Danish Cancer Registry, we examined the risk of developing breast cancer in relation to HRT in a cohort of 78,380 women aged 40-67 years from 1989 to 2002. A total of 1462 cases of breast cancer were identified during a mean follow-up of 10 years. Use of HRT did not increase the risk of breast cancer in women aged 40-49 years. Restricting the cohort to 48,812 women aged 50 years or more at entry, of whom 15 631 were HRT users, we found an increased risk associated with current use of HRT (relative risk 1.61, 95% confidence interval 1.38-1.88). The risk increased with increasing duration of use and decreased with time since last HRT prescription, reaching unity after 5 years. No material risk difference was observed among the various HRT-regimens. This population-based cohort study provides further confirmation that HRT increases the risk of developing breast cancer in women aged 50 years or more.

    This study sought to estimate the prevalence of the combination of Body Mass Index (BMI) plus Waist Circumference (WC) and of BMI plus Waist to Height Ratio (WHR) and to investigate associated factors. A two-stage random sample of adults (>20 years) living in former African slaves communities (Quilombos) was taken in Vitória da Conquista in the State of Bahia in 2011. Combined BMI+WHR nutritional risk was defined by the simultaneous presence of BMI > 25.0Kg/m2 or > 27.0Kg/m2, if aged > 60 years and WHR > 0.5. BMI + WC nutritional risk was defined by elevated BMI in addition to WC > 80cm for women, or > 94cm for men. Among the 739 participants, the prevalence of combined nutritional indicators were 35.3% (BMI + WHR) and 26.8% (BMI + WC). Female sex and hypertension increased the chances of a combination of both indicators, while being unmarried decreased the chances. The prevalence of BMI + WHR was higher in the 40-59 year age range and the prevalence of BMI + WC was higher in the 40-49 year age range. Less schooling increased the chances of the combined BMI + WHR indicator and watching television for more than two hours/day increased the chances of the BMI + WC indicator. The high prevalence of combined nutritional indicators indicate the need of diet promotion actions to prevent obesity.

    The transfer of a mixture of perfluoroalkyl acids (PFAAs) from contaminated feed into the edible tissues of 24 fattening pigs was investigated. Four perfluoroalkyl sulfonic (PFSAs) and three perfluoroalkyl carboxylic acids (PFCAs) were quantifiable in feed, plasma, edible tissues, and urine. As percentages of unexcreted PFAA, the substances accumulated in plasma (up to 51%), fat, and muscle tissues (collectively, meat 40-49%), liver (under 7%), and kidney (under 2%) for most substances. An exception was perfluorooctanesulfonic acid (PFOS), with lower affinity for plasma (23%) and higher for liver (35%). A toxicokinetic model is developed to quantify the absorption, distribution, and excretion of PFAAs and to calculate elimination half-lives. Perfluorohexanoic acid (PFHxA), a PFCA, had the shortest half-life at 4.1 days. PFSAs are eliminated more slowly (e.g., half-life of 634 days for PFOS). PFAAs in pigs exhibit longer elimination half-lives than in most organisms reported in the literature, but still shorter than in humans.

    Experiments were performed to establish a feasible treatment process for the solidification and stabilization (S/S) of soil contaminated by leaching of Cr(VI) from Chromite ore processing residue (COPR). Reduction of the highly mobile Cr(VI) was performed using calcium polysulfide (CaS5) with a dosage of 3 times the molar stoichiometric ratio for the initial concentration of Cr(VI) present in the chromium contaminated soil (CCS). The CCS was solidified and stabilized (S/S) using fly ash (FA) in various proportions i.e., 1:1, 1:2, 1:3 (FA: CCS) with and without using reducing agent i.e., CaS5. Leachability tests such as Toxicity Characteristic Leaching Procedure (TCLP) and semi-dynamic long term leachability tests indicated that the CaS5 was effective in reduction of Cr(VI) followed by the S/S process. Leachability Index was derived from the results of the semi-dynamic long term leachability tests and was between 8 and 9, indicating that FA is an effective treatment for disposal into secured landfills for CCS. The characteristic compressive strength of the CaS5 treated CCS with FA mortar blocks were between 24.47 and 40.49 kg/cm(2). Considering the cost of CaS5 and FA, a total expenditure of Rs. 7826 i.e., US $ 130.4 would be required for remediation of one tonne of CCS.

    Q fever was diagnosed in 443 patients in Northern Ireland between 1962 and 1989. From 1986 onwards there was an increase, which peaked in 1989 with 107 cases of whom 47 were infected in Ballycastle, Co Antrim. There were three outbreaks and 21 clusters of patients with Q fever. Most cases were in April and May which correlated with the peak lambing and calving season. Q fever mainly affected males in the 40-49 year old age group. County Antrim had the highest prevalence rate of 40/100,000 population and also had the most sheep. The number of sheep in Northern Ireland has doubled in the past ten years. Q fever was strongly associated with occupation and animal contact. Eighty-seven patients (19.6%) drank unpasteurized milk. The commonest presenting illnesses were pneumonia (62.8%), influenza-like illness (24.6%), involvement of the heart (9.0%) and hepatitis (1.6%). Thirty-two patients (7.2%) had endocarditis, 20 of whom had prosthetic valves and three of whom died. Coxiella burnetii was present on valves removed from seven patients.

    Thirty-four human immunodeficiency virus (HIV) specialists from 16 countries contributed to this project, whose primary aim was to provide guidance on the screening, diagnosis, and monitoring of bone disease in HIV-infected patients. Four clinically important questions in bone disease management were identified, and recommendations, based on literature review and expert opinion, were agreed upon. Risk of fragility fracture should be assessed primarily using the Fracture Risk Assessment Tool (FRAX), without dual-energy X-ray absorptiometry (DXA), in all HIV-infected men aged 40-49 years and HIV-infected premenopausal women aged ≥40 years. DXA should be performed in men aged ≥50 years, postmenopausal women, patients with a history of fragility fracture, patients receiving chronic glucocorticoid treatment, and patients at high risk of falls. In resource-limited settings, FRAX without bone mineral density can be substituted for DXA. Guidelines for antiretroviral therapy should be followed; adjustment should avoid tenofovir disoproxil fumarate or boosted protease inhibitors in at-risk patients. Dietary and lifestyle management strategies for high-risk patients should be employed and antiosteoporosis treatment initiated.

This study classified an elderly population into young-elderly and mid-elderly individuals and investigated the difference in stage transition duration between the two groups to provide basic material for assessment of dysphagia in old age. [Subjects and Methods] The subjects of the study were 12 middle-aged individuals (40-49 years), young-elderly individuals (65-74 years), and 9 mid-elderly individuals (75-84 years). Stage transition duration was defined as the time from the moment food boluses passed the ramus of the mandible until the start of upward movement of the hyoid. All image data were measured using a videofluoroscopic study. Difference in measured values for stage transition duration between the groups were confirmed with one-way analysis of variance. [Results] Although analysis of variance was significantly longer in the young-elderly and mid-elderly individuals than in the middle-aged individuals, there was no significant difference in stage transition duration between the young-elderly and mid-elderly individuals. [Conclusion] In this study, there was no significant difference between the young-elderly and mid-elderly individuals in the movement speed of muscles related to pharyngeal swallowing. PMID:27313360

    From the viewpoint of the etiologies of noise-induced permanent threshold shift (NIPTS) and vibration-induced white finger (VWF), the association between VWF and hearing loss was examined among 499 chain-saw workers who underwent a compulsory health examination for vibration syndrome. They were classified by age, duration of noise and vibration exposure, and the severity of VWF. The severity of VWF was evaluated according to the following criteria: no prior history; VWF history, but symptoms had disappeared; VWF present but appearing rarely; frequent appearance of VWF (more than 20 times per winter season). In three age groups (ie, 40-49, 50-59, 60-69 years) with 5-9 years of exposure, the chainsaw workers with VWF had a significantly greater hearing loss at higher frequencies than those without VWF. However, in the 10- to 14-year exposure groups, a significant difference was not found between the VWF and non-VWF groups, except that the 50- to 59-year age groups showed a significant difference in mean age. It was suggested that interindividual differences in susceptibility to noise and vibration may be the reason for the synergistic effects of noise and vibration.

    Breast cancer is the most deadly disease affecting women and thus it is natural for women aged 40-49 years (who have a family history of breast cancer or other related cancers) to assess their personal risk for developing familial breast cancer (FBC). Besides, as each individual woman possesses different levels of risk of developing breast cancer depending on their family history, genetic predispositions and personal medical history, individualized care setting mechanism needs to be identified so that appropriate risk assessment, counseling, screening, and prevention options can be determined by the health care professionals. The presented work aims at developing a soft computing based medical decision support system using Fuzzy Cognitive Map (FCM) that assists health care professionals in deciding the individualized care setting mechanisms based on the FBC risk level of the given women. The FCM based FBC risk management system uses NHL to learn causal weights from 40 patient records and achieves a 95% diagnostic accuracy. The results obtained from the proposed model are in concurrence with the comprehensive risk evaluation tool based on Tyrer-Cuzick model for 38/40 patient cases (95%). Besides, the proposed model identifies high risk women by calculating higher accuracy of prediction than the standard Gail and NSAPB models. The testing accuracy of the proposed model using 10-fold cross validation technique outperforms other standard machine learning based inference engines as well as previous FCM-based risk prediction methods for BC.

    This study analyzed potential drug interactions (PDIs) of antimicrobials used in patients of hematopoietic stem cell transplantation and identified associated factors. The sample consisted of 70 patients admitted to a hospital in São Paulo. The PDIs were analyzed through the consultation of the Drug Interactions Facts and Drug Interactions Handbook. Descriptive statistics and logistic regression were used. Half of the sample was exposed to 13 PDIs, which occurred with fluconazole (53.8%), ciprofloxacin (30.8%) and sulfamethoxazole-trimethoprim (15.4%). Most (92.3%) were of moderate severity, with good evidence (61.6%), early delayed effect (61.5%) and need to have their therapy monitored (76.9%). Patients with four or more medications (p<0.001), aged between 40-49 years of age (p <0.001), and being male (p<0.001) were associated with PDIs. A PDI may result in adverse outcomes, impacting patients' morbidity and mortality. Combination regimens can be safe, provided there is careful monitoring by professionals involved in care delivery.

    Biofouling control is considered as a major challenge in operating membrane systems. A lab-scale RO system was setup at a local water reclamation plant to study the feasibility of using biofiltration as a pretreatment process to control the biofouling. The biological activity in the RO system (feed, product, reject streams) was tested using the standard serial dilution plating technique. Operational parameters such as differential pressure (DP) and permeate flowrate of the system were also monitored. Effects of biofilter on AOC and DOC removals were investigated. Biofiltration was found to be a viable way of assimilable organic carbon (AOC) and dissolved organic carbon (DOC) removals, with removal efficiencies of 40-49% and 35-45% at an empty bed contact time (EBCT) of 30 min. It was also found that using the biofiltration as a pretreatment reduced the rate of biofouling. It took only about 72 h for biofouling to have a significant impact on the performance of the RO membrane, when the system was operated without using biofiltration as pretreatment. There was, however, a five times increase in operational length to more than 300 h when biofiltration was used. This study presented the suitability of the biofilter as an economical and simple way of biofouling control for RO membrane. PMID:15698653

    The technical properties of three layered cement-bonded boards (CBBs) made from wastepaper and sawdust were investigated. The CBBs were produced at three density levels of 1000, 1200 and 1300 kg/m{sup 3} and at four cement/particle ratios of 2.0:1, 2.5:1, 3.0:1 and 3.5:1 on a weight to weight basis. The technical properties evaluated were modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA) and thickness swelling (TS). The MOR values ranged from 4.85 to 11.69 MPa and MOE values ranged from 2.80 to 5.57 GPa. The mean values of WA and TS after 24 h of water soaking of the CBBs ranged from 18.18% to 40.49% and 3.55% to 12.13%, respectively. MOR and MOE of the CBBs increased with increase in board density, but MOR decreased with the increase in cement/particle ratio. On the other hand, WA and TS decreased with increase in board density and cement/particle ratio. CBBs produced from wastepaper and sawdust at cement/particle ratios of 3.0:1 and 3.5:1 are suitable for building construction such as paneling, ceiling and partitioning.

    A truncated left-censored and right-censored lognormal model has been validated for representing pleural mesothelioma survival times in the range 5-200 weeks for data subsets grouped by age for males, 40-49, 50-59, 60-69, 70-79 and 80+ years and for all ages combined for females. The cases available for study were from Europe and USA and totalled 5580. This is larger than any other pleural mesothelioma cohort accrued for study. The methodology describes the computation of reference baseline probabilities, 5-200 weeks, which can be used in clinical trials to assess results of future promising treatment methods. This study is an extension of previous lognormal modelling by Mould et al (2002 Phys. Med. Biol. 47 3893-924) to predict long-term cancer survival from short-term data where the proportion cured is denoted by C and the uncured proportion, which can be represented by a lognormal, by (1 - C). Pleural mesothelioma is a special case when C = 0.

    The authors examined 3,335 cases of suicides among the unnatural deaths in Shiga Prefecture during the 15-year period, 1974 to 1988. The results obtained were as follows: The number of suicides in a year amounted to 200 during the period from 1974 to 1982, and increased to 280 in 1983 at maximum. The cases of suicide were more in male than in female. The incidence of suicide was higher in March to July and the peak of incidence was observed in April. The highest frequency of suicides was in 40-49 year age group in male, and 70-79 year group in female. Among various procedures of suicide, hanging was most frequent during the past 15 years in both sexes, and the following procedure was carbon monoxide poisoning in male and drowning in female. As to the occupation, housewives and person without a regular occupation constituted 53.1% of the total suicidal cases, and products makers and laborers were found in 11.1%. With regarded to the causative factors, "suffering from illness" was the most frequent factor, and followed by "insanity or mental disorder", "problems of economic distress", "disagreement with family" and others.

    To assess whether the seroprevalence of canine distemper virus (CDV) and canine parvovirus (CPV) in domestic dogs is higher in urban versus rural areas of the Araucanía region in Chile and risk factors for exposure, a serosurvey and questionnaire survey at three, urban-rural paired sites was conducted from 2009 to 2012. Overall, 1161 households were interviewed of which 71% were located in urban areas. A total of 501 blood samples were analysed. The overall CDV and CPV seroprevalences were 61% (CI 90%: 58-70%) and 47% (CI 90%: 40-49%), and 89% (CI 90%: 85-92%) and 72% (CI 90%: 68-76%) in urban and rural areas, respectively. The higher seroprevalence in domestic dogs in urban areas suggests that urban domestic dogs might be a maintenance host for both CDV and CPV in this region. Due to the presence of endangered wild canids populations in areas close to these domestic populations, surveillance and control of these pathogens in urban dog populations is needed a priority.

    Early detection of breast cancer has been shown to reduce breast cancer deaths in randomised controlled trials (RCTs) of mammography in women aged 50-69 years, with weaker evidence of benefit in those aged 40-49 or 70 years and older. Magnetic resonance imaging (MRI) and ultrasonography have been evaluated in breast cancer screening, relative to, or in addition to, mammography, in selected populations; neither test has been examined in an RCT, and thus evidence of associated screening benefit is uncertain. MRI is more sensitive than mammography in screening women with suspected or proven inherited mutations of the breast cancer genes. The addition of MRI in screening this population detects 8-24 additional cancers per 1000 screens, but also significantly increases a woman's risk of being recalled for investigation or surgical biopsy for false-positive findings. In Australia, Medicare funding for MRI screening of women in specific risk groups was announced in February 2009. Ultrasonography can detect cancers not identified on mammography in asymptomatic women with dense breast tissue. Incremental ultrasound cancer detection is reported in 0.27%-0.46% of women with mammography-negative dense breasts; evidence varies on its association with false-positive findings. Computer-aided detection (CAD) is a complementary tool to mammography, prompting the reader to consider lesions on the mammogram that may represent cancer. Emerging evidence and improved CAD technology are likely to help define its role in breast screening. PMID:19413520

    The HIV-positive population, due to their immuno-compromised nature, is considered more susceptible to parasitic infections than other populations. However despite the reports of other opportunistic pathogens such as Cryptosporidium and tuberculosis reported in vulnerable communities, microsporidia have not been highlighted in the local HIV-positive population in Malaysia. This study aimed to provide preliminary information on the prevalence of microsporidia in the local HIV-population. Microsporidia were detected in 21/247 (8.5%) stool samples from the HIV-infected individuals, a significantly higher (P-value <0.05) prevalence than in the control group, in which 5/173 (2.9%) were positive. HIV patients were 3x more at risk for acquiring microspordium (OR: 3.12; 95% CI 1.15-8.44). Spores were ellipsoid in shape with outlines that stained dark pink with the interior a lighter shade. Approximately 21% of the positive specimens were from individuals in the 40-49 years age group. Ten individuals who were positive for microsporidia were also positive for other enteric parasites such as Blastocystis hominis and Giardia lamblia. We detected Encephalitozoon intestinalis DNA following nested PCR from three of 10 samples analysed, as demonstrated by an amplicon of 370bp. From the findings reported, it appears that microsporidial infection in humans may actually be more common than reported. We strongly advocate greater emphasis on personal hygiene through public education on personal hygiene and the consumption of boiled or filtered water. PMID:21596411

    This study examines the correlates of mammogram utilization among predominantly low income Asian American women using cross sectional data of women recruited through the ENCORE(plus) program (n = 1,695) between July 1996 and June 1998. Logistic regression was used to examine the independent effect of variables corresponding to Andersen's behavioral model of health services utilization on mammography screening behavior. Foreign-born women living in the U.S. < 5 years and between 5 and 10 years were significantly less likely to have ever had a mammogram than women who were born in the U.S. (OR 0.22; CI 0.12, 0.40 and OR 0.48; CI 0.27, 0.86, respectively). Women 40-49 years old were half as likely to adhere to mammography screening recommendations as women 50-64 years (CI 0.33, 0.76). Health insurance was positively associated with adherence to mammography screening guidelines (OR 1.59; CI 1.02, 2.48). The results of this study highlight the need for health education about breast cancer and mammography among Asian American women. Policy work also needs to be directed toward improving access to health care in this community.

    Objective. US primary care physicians are inadequately educated on how to provide obesity treatment. We sought to assess physician training in obesity and to characterize the perceptions, beliefs, knowledge, and treatment patterns of primary care physicians. Methods. We administered a cross-sectional web-based survey from July to October 2014 to adult primary care physicians in practices affiliated with the Massachusetts General Hospital (MGH). We evaluated survey respondent demographics, personal health habits, obesity training, knowledge of bariatric surgery care, perceptions, attitudes, and beliefs regarding the etiology of obesity and treatment strategies. Results. Younger primary care physicians (age 20-39) were more likely to have received some obesity training than those aged 40-49 (OR: 0.08, 95% CI: 0.008-0.822) or those 50+ (OR: 0.03, 95% CI: 0.004-0.321). Physicians who were young, had obesity, or received obesity education in medical school or postgraduate training were more likely to answer bariatric surgery knowledge questions correctly. Conclusions. There is a need for educational programs to improve physician knowledge and competency in treating patients with obesity. Obesity is a complex chronic disease, and it is important for clinicians to be equipped with the knowledge of the multiple treatment modalities that may be considered to help their patients achieve a healthy weight.

    The low-heat-value cornstalk gas produced in the down-flow fixed bed gasifier was tentatively used for methanol synthesis. The cornstalk gas was purified and the technical procedures such as deoxygenation, desulfurization, catalytic cracking of tar, purification and hydrogenation were studied. The catalytic experiments of methanol synthesis with cornstalk syngas were carried out in a tubular-flow integral and isothermal reactor. The effect of reaction temperature, pressure, catalyst types, catalyst particle size, syngas flow at entering end and composition of syngas was investigated. The optimum process conditions and yield of methanol from cornstalk syngas were obtained. The experimental results indicated that the proper catalyst for the synthetic reaction was C301 and the optimum catalyst size was 0.833 mm x 0.351 mm. The optimum operating temperature and pressure were found to be 235 degrees C and 5 MPa, respectively. The suitable syngas flow 0.9-1.10 mol/h at entering end was selected and the best composition of syngas were CO 10.49%, CO2 8.8%, N2 37.32%, C(n)H(m) 0.95% and H2 40.49%. The best methanol yield was 0.418 g/g cornstalk. This study provided the technical support for the industrial test of methanol production from biomass (cornstalk) gas.

    A retrospective study was carried out in five main General District and Teaching Hospitals in Tehran (18 general surgical wards) to investigate breast cancer in Tehran, Iran. All patients who have had breast pathology during 1985-95 were reviewed. For each patient the following data were extracted from case records sex, age, type of disease (based on ICD-10 and ICD-O), breast cancer pathology, tumor size, lymph node involvement, pathological staging (based on TNM system), type of surgery, mass location and the affected side of breast. In all 3085 records were reviewed. Of these, in 903 cases the final diagnosis was breast cancer. The mean age of breast cancer patients was 47.1 (SD=12.3) y and the age-adjusted analysis showed that the observed number of breast cancer cases in the age group 40-49 was higher than expected (P<0.001). The majority of patients (71%) were patients with infiltrating ductal carcinoma, 70% had advanced disease (Stage III), and in 51% of cases the tumour was more than 5 cm in size. Finally it was found that two-third of patients (76%) underwent modified radical mastectomy. Although this study does not address true incidence, but rather frequency, the findings suggest that the Iranian breast cancer patients are relatively younger than their western counterparts and mostly have locally advanced disease. In terms of breast cancer screening programs, these findings have some implications for public health professionals in Iran.

    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.

    Background: Currently breast cancer (BRCA) still remain the most commonly diagnosed female cancer globally with a significant geographic, racial and ethnical variations in its incidence. Aim: This article examines the frequency and histological types and grades of BRCA in a pioneer teaching Hospital in Delta State, Nigeria. Materials and Methods: H and E stained-slides of breast biopsies diagnosed at the Central Hospital, Warri from 2005 to 2011 were archived and studied. Request forms were scrutinized for clinical bio-data, diagnosis and histological sections were analyzed. Data obtained were analyzed using the Statistical Package for the Social Sciences version 17 statistical package (SPSS) Incorporated, Chicago, Illinois, USA, and value presented descriptively. Results: During this period, 905 breast lesions were seen. Out of this, 261 were BRCAs, of which 260 cases were females and one case was a male. The peak age incidence for BRCA and its variants was 40-49 years accounting for (n = 94/261; 36%). The mean age of BRCA was 46 years (6.2). Invasive carcinoma of no special type (NST) was the most commonly encountered histological group of breast carcinoma constituting (n = 203/261, 77.7%) with the high grade invasive ductal carcinoma as the leading diagnosis. Conclusion: Majority of BRCAs encounter was invasive ductal carcinoma of NST with bulk of patients presenting in Stages III and IV. PMID:24971211

    The aim of this study was to describe the change in vegetable consumption with ageing and the transition to retirement. Study subjects were the participants of the GAZEL prospective cohort (Gaz and Électricité de France) aged 40-49 years at inclusion in 1989 who retired between 1991 and 2008 (12,942 men and 2739 women). Four FFQ were completed from 1990 to 2009. We used multiple imputation by chained equations in order to avoid dropping incomplete cases. The OR for eating vegetables everyday was estimated as a function of ageing, retirement status and the place of lunch before retirement through generalised estimating equations. Analyses were stratified by sex, and models were adjusted for confounders, including current spousal status. In 1990, 17.7% of men and 31% of women reported eating vegetables daily. The odds of consuming vegetables everyday increased with ageing for both men and women. The usual place of lunch was home for less than half the sample before retirement and for almost every respondent after retirement. For those who changed their place of lunch, the association between being retired and the odds of eating vegetables daily was positive and significant. We found that, in this cohort, vegetable consumption increased with ageing. Retirement had an indirect effect on vegetable consumption mediated by changes in the place of lunch.

    Urinary tract infection (UTI) is one of the most common infections in children. Urine culture remains the gold standard for diagnosis, but the utility of urine Gram stain relative to urinalysis (UA) is unclear. We reviewed 312 pediatric patients with suspected UTI who had urine culture, UA, and urine Gram stain performed from a single urine specimen. UA was considered positive if ≥10 leukocytes per oil immersion field were seen or if either nitrates or leukocyte esterase testing was positive. Urine Gram stain was considered positive if any organisms were seen. Sensitivity, specificity, and positive and negative predictive values were calculated using urine culture as the gold standard. Thirty-seven (12%) patients had a culture-proven UTI. Compared to urine Gram stain, UA had equal sensitivity (97.3% versus 97.5%) and higher specificity (85% versus 74%). Empirical therapy was prescribed before the Gram stain result was known in 40 (49%) patients and after in 42 (51%) patients. The antibiotics chosen did not differ between the two groups (P=0.81), nor did they differ for patients with Gram-negative rods on urine Gram stain compared to those with Gram-positive cocci (P=0.67). From these data, we conclude that UA has excellent negative predictive value that is not enhanced by urine Gram stain and that antibiotic selection did not vary based on the urine Gram stain result. In conclusion, the clinical utility of urine Gram stain does not warrant the time or cost it requires.

    In this paper, a new index designed to measure the relative availability of unmarried men and women is introduced. Termed the "Availability Ratio," the measure is defined as the number of suitable persons divided by the average competition. Suitability, in turn, is defined in terms of race, age and education. After various experimental tests, particular age and eeducational constraints were empirically derived from marriage data. Persons of opposite sex sharing living quarters are tested as unavailable. Estimates are also made of those presumed to be unsuitable on the basis of the % of persons aged 45-74 who have never married. Adjustments for the census undercount are given. 1980 and 1970 estimates are presented for the US population. Subsequent analyses will focus on metropolitan areas, which are more likely to function as actual marriage markets in contrast to the nation as a whole. The substantive evidence indicates that women under 25 are in a good position to find a mate, but that after this age, their prospects deteriorate rapidly. The outlook is especially poor for the more educated women at older ages, especially black women. At ages 40-49, for example, there are fewer than 3 suitable men available for every 10 college-educated women. The results suggest that the combination of preferences of women for older men (or men's tastes for younger women), combined with higher survival rates for women at older ages, results in a very unbalanced market situationn for all but the youngest cohorts of men and women.

    For screening efforts to maximally reduce mortality in the general population, a large proportion of women need to utilize mammography routinely. To investigate utilization of mammography in a community setting, the authors used population-based data collected by the New Mexico Mammography Project for residents of the Albuquerque, New Mexico, metropolitan area for the period 1994-1997. The authors computed screening rates and the proportion of women who routinely use mammography. The utilization of mammography was low. Only 50% of the women aged 50-74 years were screened each year. Less than one third of women aged 40-49 years or 75 years and older were screened annually. The percentage of women who routinely used mammography on an annual or biennial basis was low in all age groups, especially among Hispanics and American Indians. Women aged 50-74 years had the highest percentage of routine annual mammography use, ranging from 30% in non-Hispanic Whites to 20% in Hispanics. Current utilization of mammography in community-based screening efforts is unlikely to achieve a potential 30% reduction in breast cancer mortality. Interventions are needed to increase the routine use of mammography.

    Studies of diet and health focus increasingly on dietary patterns. Although the traditional Mediterranean diet is perceived as being healthy, there is little information on its possible benefit to young people. We studied whether closer adherence to the traditional Mediterranean dietary pattern was associated with overall and cancer mortality in a cohort of 42,237 young women, aged 30-49 years at enrollment, who were recruited in 1991-2 from the general population in the Uppsala Health Care Region, Sweden, and followed up, almost completely, for about 12 years. Adherence to the Mediterranean diet was assessed by a 10-point score incorporating the characteristics of this diet. Among women less than 40 years old at enrollment--whose causes of death are mainly cancer with probable genetic influences, injuries or suicide--there was no association of the Mediterranean diet score with total or cancer mortality. Among women 40-49 years old at enrollment, a 2-point increase in the score was associated with considerable reductions in overall mortality (13%; 95% CI 1%, 23%; P approximately 0.05) and cancer mortality (16%; 95% CI -1%, 29%; P approximately 0.06). Few cardiovascular deaths occurred in this cohort of young women. The findings of the present study in a northern European population of young women indicate that closer adherence to a Mediterranean dietary pattern reduces mortality even among young persons.

    Comparison of two major studies conducted by National family health survey (NFHS-2) in 1998-1999 and NFHS-3 in 2005-2006 shows that prevalence of obesity among Indian women has elevated from 10.6% to 12.6% (increased by 24.52%). The prevalence is more profound in the women of age between 40-49 years (23.7%), residing in cities (23.5%), having high qualification (23.8%), belonging to Sikh community (31.6%) and households in the highest wealth quintile (30.5%). Highest percentage of obese women is found in Punjab (29.9%). Although this number seems small in the international perspective, it is significant because of the sheer size of population in India. While the problem of under-nutrition still exists in many parts of India, the additional burden of obesity due to increasing sedentary lifestyle, junk food habits in some urban and economically sound areas is really alarming. Prevention and control of this serious problem through awareness programmes to adopt diversified nutritional food and healthy lifestyle are strongly recommended.

    The epidemiological characteristics of benign prostate hyperplasia (BPH) in mainland China are not completely understood. We performed this meta-analysis to assess the prevalence of BPH from 1989 through 2014. A total of 14 articles and 19 datasets were included. The pooled overall prevalence of BPH among men aged 40 years and older was 36.6% [95% CI, 32.3-44.8]. The occurrence rate of BPH in the age groups 40-49 years, 50-59 years, 60-69 years, 70-79 years and 80 years and older was 2.9%, 29.0%, 44.7%, 58.1% and 69.2%, respectively. The pooled occurrence rate of BPH was 41.5% [95% CI, 34.5-48.4] in urban areas and 38.6% [95% CI, 22.7-54.6] in rural areas; this difference in prevalence was not statistically significant [OR, 1.51; 95% CI, 0.97-2.36]. BPH is highly prevalent in mainland China, and its prevalence increased with age. The trend in the prevalence of BPH in mainland China was not steady; the prevalence map based on a geographic information system (GIS) showed an unequal geographic distribution. High-quality surveys on BPH with a larger sample size are needed throughout mainland China to confirm these findings.

    OBJECTIVES—The purpose was to define the incidence and case fatality rates of subarachnoid haemorrhage in the population of Devon and Cornwall.
METHODS—A retrospective population based design was employed with multiple overlapping methods of case ascertainment. A strict definition of subarachnoid haemorrhage was used. Age and sex specific incidence rates and relative risks for death at different time intervals are calculated.
RESULTS—Eight hundred cases of first ever subarachnoid haemorrhage were identified; 77% of cases were verified by CT, 22% by necropsy, and 1% by lumbar puncture. The incidence rates are higher than those previously reported in the United Kingdom. The age standardised incidence rate (/100 000 person-years) for females was 11.9 (95% confidence interval (95% CI) 9.5-15.0), for males 7.4 (5.4-10.0), and the total rate was 9.7 (7.5-12.6). The case fatality rates at 24 hours, 1 week, and 30 days were 21 (18-24)%, 37 (33-41)%, and 44 (40-49)% respectively. The relative risk for death at 30days for those over 60 years:under 60 years was 2.95 (2.18-3.97).
CONCLUSION—The incidence of subarachnoid haemorrhage in the United Kingdom is higher than previously reported. Three quarters of the mortality occurs within 3days.

    Objectives: To evaluate the efficacy of trimetazidine dihydrochloride as a treatment for chronic tinnitus. Methods: A total of 97 chronic tinnitus patients were evaluated in this randomized, prospective, double-blind, placebo-controlled trial. After assessing for eligibility, 82 patients were randomly assigned into placebo or trimetazidine groups according to the medication. The trimetazidine group received 20×3 mg/day per oral trimetazidine dihydrochloride and the placebo group received 20×3 mg/day per oral placebo for 3 months. Tinnitus handicap inventory (THI), visual analogue scale (VAS) questionnaires and audiometric results were used to determine the effectiveness of trimetazidine treatment. Results: The study group comprised 82 tinnitus subjects, 42 (51%) of whom received trimetazidine dihydrochloride and 40 (49%) who received placebo. There was no significant difference between placebo and trimetazidine groups in THI grade and VAS (both pre- and posttreatment scores) (P>0.05) and no significant improvement was observed in subjective loudness score in either group (P>0.05). Additionally there was no significant difference between groups in pre- and posttreatment pure tone hearing thresholds at all measured frequencies (P>0.05). Conclusion: Trimetazidine dihydrochloride therapy was ineffective for relieving chronic tinnitus. PMID:27230273

    This study was designed to test the association of smoking with four clinically apparent conditions that may be related to altered sex steroids: natural and induced menopause, infertility, oligomenorrhea, and hirsutism. Data were obtained from the personal inventories of 50,145 women ages 20-59 years in TOPS, a weight reduction program. The age-adjusted odds ratios of each condition for heavy smokers compared with nonsmokers were 1.59 for natural menopause, 1.49 for induced menopause, 1.35 for infertility, 1.30 for oligomenorrhea among women younger than 40 years, 1.63 for oligomenorrhea among women 40-49 years, and 1.54 for hirsutism (P less than .05 for oligomenorrhea and P less than .001 for all other risks). The odds ratios were not substantially changed after adjustment for obesity, parity, and husband's education level. These results suggest that smoking may affect the ovaries or hormone metabolism, or both, with medical and cosmetic consequences. PMID:3108939

    A techno-economic analysis was conducted for a simplified lignocellulosic ethanol production process developed and proven by the University of Florida at laboratory, pilot, and demonstration scales. Data obtained from all three scales of development were used with Aspen Plus to create models for an experimentally-proven base-case and 5 hypothetical scenarios. The model input parameters that differed among the hypothetical scenarios were fermentation time, enzyme loading, enzymatic conversion, solids loading, and overall process yield. The minimum ethanol selling price (MESP) varied between 50.38 and 62.72 US cents/L. The feedstock and the capital cost were the main contributors to the production cost, comprising between 23-28% and 40-49% of the MESP, respectively. A sensitivity analysis showed that overall ethanol yield had the greatest effect on the MESP. These findings suggest that future efforts to increase the economic feasibility of a cellulosic ethanol process should focus on optimization for highest ethanol yield. PMID:26918837

    Two new species of Coccidia (Apicomplexa: Eimeriidae) are described from European accipitrid raptors (Falconiformes: Accipitridae). Oöcysts of Carvospora aquilae n. sp. found in faeces of the gold eagle Aquila chrysaetos are subspherical to broad ellipsoidal and measure 43 (40-49) x 37.5 (34-39) microm. Polar granule, oöcyst residuum and micropyle are absent. Each oöcyst contains one spherical to subspherical slightly polygonal sporocyst measuring 23.8 (23-25) x 23.3 (22-25) microm. Stieda and substieda bodies are absent. The sporocyst residuum is composed of numerous small granules less than 0.5 microm in diameter dispersed randomly among the sporozoites. Sporulated oöcysts of Carvospora circi n. sp. from faeces of the marsh harrier Circus aeruginosus are widely oval, measuring 24.5 (23-25) x 21.8 (21-24) microm. A polar granule, oöcyst residuum and micropyle are absent. Each oöcyst contains one spherical to subspherical sporocyst measuring 16.2 (15-17) x 15.6 (15-17) microm. A compact granular, spherical to subspherical sporocyst residuum, 10.4 (10-11) x 8.5 (7-9), was present in 76% of measured sporocysts. In 24% of sporocysts the granules of sporocyst residuum were scattered among the sporozoites. PMID:10803432

    The Rush Mining District along the Buffalo River in Arkansas has a significant history of zinc and lead mining operations. The tails and spoils of these operations deposit heavy amounts of raw ore into streams. One element commonly found in the earth's crust that becomes a minor constituent of the deposition is cadmium. Periphyton samples from Rush Creek and Clabber Creek, two creeks within the Rush Mining District were measured for cadmium as well as two creeks with no history of mining, Spring Creek and Water Creek. Periphyton samples from Rush and Clabber Creek contained mean cadmium concentrations of 436.6 ± 67.3 and 93.38 ± 8.67 µg/kg, respectively. Spring Creek and Water Creek had a mean cadmium concentration of 40.49 ± 3.40 and 41.78 ± 3.99 µg/kg within periphyton. The results indicate increased metal concentrations in algal communities from mined areas. As periphyton is the base of the aquatic food chain, it acts as a conduit for movement of cadmium in the food web.

    Experiments were performed to establish a feasible treatment process for the solidification and stabilization (S/S) of soil contaminated by leaching of Cr(VI) from Chromite ore processing residue (COPR). Reduction of the highly mobile Cr(VI) was performed using calcium polysulfide (CaS5) with a dosage of 3 times the molar stoichiometric ratio for the initial concentration of Cr(VI) present in the chromium contaminated soil (CCS). The CCS was solidified and stabilized (S/S) using fly ash (FA) in various proportions i.e., 1:1, 1:2, 1:3 (FA: CCS) with and without using reducing agent i.e., CaS5. Leachability tests such as Toxicity Characteristic Leaching Procedure (TCLP) and semi-dynamic long term leachability tests indicated that the CaS5 was effective in reduction of Cr(VI) followed by the S/S process. Leachability Index was derived from the results of the semi-dynamic long term leachability tests and was between 8 and 9, indicating that FA is an effective treatment for disposal into secured landfills for CCS. The characteristic compressive strength of the CaS5 treated CCS with FA mortar blocks were between 24.47 and 40.49 kg/cm(2). Considering the cost of CaS5 and FA, a total expenditure of Rs. 7826 i.e., US $ 130.4 would be required for remediation of one tonne of CCS. PMID:25942695

    Binge-like alcohol exposure during the early postnatal period in rats and mice causes deficits in spatial learning and memory that persist into adulthood. Wozniak et al. (2004) reported that heavy binge alcohol exposure on postnatal day 7 (PD 7) in C57BL/6 (B6) mice produced profound spatial learning deficits in the Morris water maze when tested in adolescence (P30-39); when tested in adulthood, however, the deficits were greatly attenuated. Using a similar PD 7 binge alcohol exposure paradigm in B6 mice, we tested whether a single-day (PD 7 only) alcohol treatment produced place learning deficits in both adolescence and in adulthood, and further tested whether a more extended (3-day, PD 7-9) alcohol exposure would induce more severe and enduring deficits. B6 mice were given either 2 subcutaneous injections of alcohol (2.5 g/kg each) 2 h apart on PD 7 or on PD 7-9, and compared with controls that received saline vehicle injections and controls that received no injections. The alcohol injections on PD 7 produced average peak blood alcohol concentrations of 472 mg/dL and evoked typical patterns of activated caspase-3-positive neurons in the cortex, hippocampal formation, and striatum 6 h after the last injection. Mice were given standard place training or random location training in the Morris water maze either as adolescents (PD 30-39) or adults (PD 70-79). The adolescents acquired the place learning more slowly than adults, and the alcohol treatments produced only modest place acquisition deficits. In contrast, both the PD7 and the PD 7-9 alcohol treatments resulted in large and significant spatial learning impairments in adults. In contrast to the previous findings of Wozniak et al. (2004), these results indicate that binge alcohol exposure in the 3rd trimester equivalent produces significant and enduring deficits in spatial learning in B6 mice.

    Background It is unclear whether an “obesity paradox” exists in the respiratory system, especially in acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). Previous studies have postulated a causal relation between obesity and ARDS/ALI but have lacked power to form a definitive conclusion. Objective To investigate the relationships between obesity, ARDS/ALIrisk, and mortality. Methods A systematic search current to April 2016 was performed in Pubmed, EMBASE, Medline, Cochrane databases to find relevant studies. All studies that estimate the effect of obesity in the morbidity and mortality of ARDS/ALI were included. Results A total of 24 studies including 9,187,248 subjects were analyzed. The combined results from 16 studies that examined the effect of obesity in morbidity of ARDS/ALI showed an89% increase in odds ratio(pooled odds ratios (OR) 1.89, 95% confidence intervals (CI) 1.45 to 2.47). In subgroup analysis, compared to normal weight, obesity was associated with an increased risk of ARDS/ALI (OR1.57, 95% CI 1.30–1.90 for obese (BMI30-39.9kg/m2); OR1.75, 95% CI 1.42–2.15 for obese(BMI≥30kg/m2); OR1.67, 95% CI 1.04–2.68 for morbid obese(BMI≥40kg/m2)). The combined results from 9 studies that examined the effect of obesity in mortality of ARDS/ALI had a pooled odds ratio(pooled OR 0.63, 95% CI 0.41 to 0.98). Inversely, obesity was significantly associated with reduced risk of ARDS/ALI mortality(OR0.88, 95% CI 0.78–1.00 for overweight(BMI≤18.5m2); OR0.74, 95% CI 0.64–0.84 for obese (BMI30-39.9kg/m2);OR0.84, 95% CI 0.75–0.94 for 60days mortality; OR0.38, 95% CI 0.22–0.66 for 90days mortality). Conclusions Our data identify obesity as an important risk factor for the development of ARDS/ALI; however, ARDS/ALI outcomes are improved in this population when compared to individuals with a normal body mass index. This meta-analysis results supported ‘‘obesity paradox” in ARDS/ALI. PMID:27684705

  10. Erectile dysfunction heralds onset of cardiovascular disease.

    Erectile dysfunction (ED) was once assumed to be a psychological condition but has now been shown to share risk factors with cardiovascular disease including age, diabetes mellitus, smoking, hypertension and hypercholesterolaemia, suggesting an underlying vascular pathology. Evidence reveals that there is a potential link between ED and subsequent development of coronary artery disease. ED itself may also increase cardiovascular risk. The relative risk of developing coronary artery disease within ten years, in patients with moderate to severe ED, has been calculated as 14% in men aged 30-39 years and may be as high as 27% in those aged 60-69. The association appears greater when younger men presenting with ED are considered. The severity of ED has also been linked with the severity of coronary artery disease The proposed pathological mechanisms are based on a theory of endothelial dysfunction which eventually leads to atherosclerosis. This occurs first in more vulnerable narrow diameter vessels such as the cavernosal arteries. The artery size hypothesis may explain why ED occurs before manifestation of coronary artery disease. There is likely to be a delay between presentation with ED and clinical presentation with coronary artery disease. In one study, ED was found to present 39 months prior to coronary symptoms. This provides GPs with a valuable window of opportunity for risk assessment, subsequent primary prevention and early referral to a cardiologist. PMID:27552797

    Sixty Giardia duodenalis isolates from domestic (n=49) and wild (n=11) animals (dogs, cats, deers, wolves, raccoon dog and muskrat) were analysed by PCR-RFLP at glutamate dehydrogenase locus (gdh). The isolates were obtained from positive feces samples for Giardia cysts analysed by flotation technique with saturated sodium chloride solution (specific gravity 1.28). Three G. duodenalis genotypes were identified: C (10/60; 16.7%); D (42/60; 70.0%); and E (7/60; 11.7%). In dogs all three genotypes were found, with the following prevalences: 76.9% genotype D (30/39); 23.1% C (9/39); 2.6% genotype E (1/39). One dog was co-infected with C and D genotypes. In cats we identified only G. duodenalis genotype D. Wolves and raccoon dog harbored infection with G. duodenalis genotype D, deers with E type and muskrat C type. This is the first study regarding genotyping of G. duodenalis in cats and wild animals from Romania. To the best of our knowledge, this is the first report of assemblages E in roe deers; assemblage C in wolves and muskrat; and assemblage D in raccoon dog. PMID:26827864

    A telephone interview of 1256 adults age 18 and over was conducted using a random digit dialing procedure. Participants were queried about their perceptions of being at risk for contracting the acquired immune deficiency syndrome (AIDS), optimism-pessimism about the controllability of the epidemic, whether they take special steps to avoid catching AIDS, and how they would prioritize three possible courses of action. The sample was about evenly divided between optimism and pessimism about controlling AIDS within five years; 10% perceived they were at least at some risk of contracting AIDS (with such "at risk" persons overrepresented among residents in the east, among college graduates, and within the 30-39 age bracket). Forty-one percent indicated taking special steps to avoid AIDS, with higher percentages of Blacks, Hispanics, and persons under age 30 reporting such precautions. Personal preventive action was ranked first among the three possible courses of action by 51%, unlimited governmental spending to find a cure or vaccine and governmental restrictions of certain homosexual behaviors were each ranked first by about 20% of the respondents. The results also indicated that perception of being at risk mediates some opinions about AIDS.

    Roach (Rutilus rutilus) were exposed, along with their appropriate controls, to a simulated bleached kraft mill effluent (KME-Sa + CP) first for 38 days at a concentration of 0.035 X LC50 and then for 14 days at 0.07 X LC50. During the experiment, their tolerances to KME-Sa + CP were tested five times by measuring the 48-hr LC50 values. In addition, the growth of roach was monitored. At the end of the exposure, accumulation of (/sup 14/C)pentachlorophenol in various parts of the fish (total PCP in water 15.6 micrograms/liter) was measured. When the fish were preexposed to KME-Sa + CP, the acute tolerance of this mixture in roach increased by 30-39%, but the response was abolished in 31 days. Fish growth remained unchanged during the experiment. Measurement of PCP accumulation revealed no difference in the absorption rate, but under steady-state conditions the degree of bioconcentration was 16% lower (P less than 0.02) in preexposed roach than in their unexposed controls. This difference was entirely accounted for in the head and visceral parts of the fish. Even when no final changes were noted in tolerance and growth rate of the fish, the authors suggest that the significantly lowered body burden implied acclimatizatory compensation under subchronic exposure of this xenobiotic.

    A new multi-model approach (MMA) for sweat loss prediction is proposed to improve prediction accuracy. MMA was computed as the average of sweat loss predicted by two existing thermoregulation models: i.e., the rational model SCENARIO and the empirical model Heat Strain Decision Aid (HSDA). Three independent physiological datasets, a total of 44 trials, were used to compare predictions by MMA, SCENARIO, and HSDA. The observed sweat losses were collected under different combinations of uniform ensembles, environmental conditions (15-40°C, RH 25-75%), and exercise intensities (250-600 W). Root mean square deviation (RMSD), residual plots, and paired t tests were used to compare predictions with observations. Overall, MMA reduced RMSD by 30-39% in comparison with either SCENARIO or HSDA, and increased the prediction accuracy to 66% from 34% or 55%. Of the MMA predictions, 70% fell within the range of mean observed value ± SD, while only 43% of SCENARIO and 50% of HSDA predictions fell within the same range. Paired t tests showed that differences between observations and MMA predictions were not significant, but differences between observations and SCENARIO or HSDA predictions were significantly different for two datasets. Thus, MMA predicted sweat loss more accurately than either of the two single models for the three datasets used. Future work will be to evaluate MMA using additional physiological data to expand the scope of populations and conditions.

    1996-10-01

    Nutrient intake was surveyed by the total food duplicate method in 49 adult ethnically Malay women (at the ages of 18 to 47 years and mostly at 30-39 years) working in Kuala Lumpur, Malaysia. Simultaneously, hematological examinations, serum biochemistry, anthropometry and clinical examination were conducted. Nutrient intakes were estimated in reference to the weight of each food item and the standard food composition tables. Lunch was the most substantial meal of the day with rice as a staple food. Compared with the Recommended Dietary Allowance (RDA) values, daily intakes of energy (1,917 kcal as an arithmetic mean), protein (62.2 g), vitamin B1 (0.83 mg) and vitamin B2 (1.18 mg) were sufficient, but intakes of minerals [i.e., calcium (347.8 mg) and iron (12.5 mg)] and some vitamins [i.e., vitamin A (equivalent to 627 micrograms retinol) and niacin (7.84 mg)] were less than RDA. When evaluated on an individual basis, the prevalence of those who took less than 80% RDA was highest for iron (92%), followed by niacin (80%), calcium (57%) and vitamin A (57%). The presence of 7 hypohemoglobinemia cases may be related to the insufficient iron intake. Overweight cases (14 women) were also detected, the prevalence of which increased at advanced ages. Lipid intake was rather high (28% of total food on energy basis), for which the major source was plants with limited contribution from fish/shellfish.

    The aim of this study was to determine the effect of six-month-long physical exercise programme with a two-time exposure to whole-body cryostimulation (WBC) in 20 sessions on antioxidant enzyme activities, lipid profile, and body composition changes in obese people (30 adult subjects; BMI = 30.39 ± 4.31 kg/m2). Blood samples were taken before the programme, one month following the exercise programme, before and after the first WBC treatment, six months following the exercise programme, after the second WBC treatment, and finally one month after the intervention. Six months of moderate aerobic activity combined with WBC did not change body mass or fat and lean body mass percentages, or circulating adiponectin, leptin, and resistin concentrations. In response to intervention a significant decrease in the level of low-density lipoprotein and triglycerides was observed, with a slight increase in high-density lipoprotein concentration. The nature of changes in the activity of respective antioxidant enzymes was not identical. After one month of increased physical activity, a significant decrease in superoxide dismutase, catalase, and glutathione reductase activities was observed (13%, 8%, and 70%, resp.). The SOD activity increased significantly after successive whole-body cryostimulation sessions. As regards catalase, a significant progressive decrease in its activity was observed. PMID:26171117

    This study compared five widely used globally gridded biomass burning emissions inventories for the 2002-2011 period (Global Fire Emissions Database 3 (GFED3), Global Fire Emissions Database 4 (GFED4), Global Fire Assimilation System 1.0 (GFAS1.0), Fire INventory from NCAR 1.0 (FINN1.0) and Global Inventory for Chemistry-Climate studies-GFED4 (G-G)). Average annual CO2 emissions range from 6521.3 to 9661.5 Tg year(-1) for five inventories, with extensive amounts in Africa, South America and Southeast Asia. Coefficient of Variation for Southern America, Northern and Southern Africa are 30%, 39% and 48%. Globally, the majority of CO2 emissions are released from savanna burnings, followed by forest and cropland burnings. The largest differences among the five inventories are mainly attributable to the overestimation of CO2 emissions by FINN1.0 in Southeast Asia savanna and cropland burning, and underestimation in Southern Africa savanna and Amazon forest burning. The overestimation in Africa by G-G also contributes to the differences.

    Partner negotiation and insertion difficulties are key barriers to female condom (FC) use in sub-Saharan Africa. Few FC interventions have provided comprehensive training in both negotiation and insertion skills, or focused on university students. In this study we explored whether training in FC insertion and partner negotiation influenced young women's FC use. 296 female students at a South African university were randomized to a one-session didactic information-only minimal intervention (n= 149) or a two-session cognitive-behavioral enhanced intervention (n= 147), which received additional information specific to partner negotiation and FC insertion. Both groups received FCs. We report the 'experiences of' 39 randomly selected female students who participated in post-intervention qualitative interviews. Two-thirds of women reported FC use. Most women (n= 30/39) applied information learned during the interventions to negotiate with partners. Women reported that FC insertion practice increased their confidence. Twelve women failed to convince male partners to use the FC, often due to its physical attributes or partners' lack of knowledge about insertion. FC educational and skills training can help facilitate use, improve attitudes toward the device and help women to successfully negotiate safer sex with partners. Innovative strategies and tailored interventions are needed to increase widespread FC adoption. PMID:26956041

    This study describes bone mineral density (BMD) and the prevalence of osteoporosis in women and men between 30-89 years in an unselected population. BMD was measured in g/cm(2) at total hip and femoral neck by dual-energy-X-ray absorptiometry in 3,094 women and 2,132 men in the 2001 Tromsø Study. BMD levels were significantly explained by age and declined progressively in both sexes from middle into old age, with highest decline in women. With osteoporosis defined as a T-score of two and a half standard deviation below the young adult mean BMD, the prevalence at the total hip in subjects above 70 years was 6.9% in men and 15.3% in women, respectively, using the Lunar reference material for T-score calculations. The prevalence increased significantly to 7.3% in men and 19.5% in women, when T-scores were calculated on basis of the young adult mean BMD (age group 30-39 years) in the study population. At the femoral neck, prevalence of osteoporosis increased from 13.5 to 18.5% in men, and from 20.4 to 35.2% in women above 70 years, respectively, depending on how T-scores were calculated. The study highlights the challenges with fixed diagnostic levels when measuring normally distributed physiologic parameters. Although BMD only partly explains fracture risk, future studies should evaluate which calculations give optimal fracture prediction. PMID:19296062

    The aim was to examine the accuracy of unconditioned behavioural observation audiometry (BOA) in predicting hearing acuity in children and the validity of test results at various frequencies. The study was designed to longitudinally compare each child's best BOA response level (at the age >12 months) with the conclusive pure-tone threshold of the better ear. The subjects were 119 children derived from a material of 353 children fitted with a hearing aid at Helsinki University Central Hospital. BOA was carried out on 119 children, 19 of whom did not respond to frequency-specific stimuli. The predictive power of BOA depended on the severity of hearing loss. At the hearing level of 30-39 dB, BOA registered 10-15 dB poorer levels than the pure-tone audiometry. The pure-tone averages (0.5, 1, 2 kHz) of 50-69 dB agreed best with the BOA responses. In severe impairments (more than 70 dB HL), the BOA registered too good hearing. Correlation of the results from the two modes to measure hearing level was highly significant (r = 0.71, p = 0.000), and the pure-tone hearing level agreed with that of BOA at the frequencies 0.5 to 4 kHz. Our results show that BOA averages < or =30 dB rarely indicate hearing loss demanding fitting of a hearing aid.

    Objectives i) to identify factors that contribute to the global trend of the higher incidence of male drowning relative to females, and; ii) to explore relationships between such factors from mortality data in New Zealand. Methods Drownings from 1983 to 2012 were examined for: Age, Ethnicity, Site, Activity, Buoyancy and Alcohol. Conditional frequency tables presented as mosaic plots were used to assess the interactions of these factors. Results Alcohol was involved in a high proportion of Accidental Immersion drownings (61%) and was highest for males aged 20-24 years. When alcohol was involved there were proportionally more incidences where a life jacket was Available But Not Worn and less incidences where a life jacket was Worn. Many 30-39 year old males drowned during underwater activities (e.g., snorkeling, diving). Older men (aged +55 years old) had a high incidence of drowning while boating. Different ethnicities were over-represented in different age groups (Asian men aged 25-29, and European men aged 65-74) and when involved in different activities. Conclusions Numerous interacting factors are responsible for male drownings. In New Zealand, drowning locations and activities differ by age and ethnicity which require targeted intervention strategies. PMID:26083689

    There is an increasing burden of obesity and obesity-related noncommunicable diseases in Gulf Cooperation Council countries, including Oman. This descriptive, epidemiological study assessed physical activity among 2977 Omani adults using a population-based household survey in 2008. Overall, 54.2% of men and 41.6% of women were physically active; the rate was higher in younger cohorts and varied significantly by region of residence. Physical activity related to the transportation (walking and cycling) domain was higher than in the leisure or work domains. Unmarried men aged 30-39 years were twice as likely to be physically active (OR 2.25) and unmarried women aged 40+ years were half as likely to be active (OR 0.58) than their married counterparts. Young women not working were less active (OR 0.18) than working women. Higher education was significantly associated with leisure activity for men aged 30+ years and women aged 40+ years. Further research to understand regional variations and to identify culturally appropriate strategies to promote physical activity is required.

    Birth weight was analyzed among singleton live births (N = 665) in Upstate New York in 1974 to women who used oral contraceptives (OC) in comparison to live births to women who used no contraceptives (N = 716), within 11 months prior to last menstrual period (LMP). In addition, birth weight was examined among live births to women who received hormone support therapy (N = 97) and hormone pregnancy tests (N = 75) during pregnancy. There was no evidence for a reduction in mean birth weight, or an increase in frequency of lower weights, among births to OC users, including those who stopped using OC within 2 months of LMP. Generally similar findings held within three maternal age groups (less than 25, 25-29, and 30-39 years). There was no evidence for a reduction in birth weight among offspring of women who received hormone pregnancy tests. Mean birth weight was relatively low among male and female births to women who received hormone therapy for "threatened abortion," but this may reflect the selection of women for such treatment rather than an effect of exogenous hormones on fetal growth.

    Individuals differ in the intensity with which they typically experience affect as well as in their beliefs regarding their ability to alleviate negative mood states. These variables have been implicated in a range of clinical problems. Most studies utilize a single index of affect intensity. The differential correlates of positive and negative affect intensity, their association with negative mood regulation expectancy and their role as predictors of psychological outcomes have been insufficiently explored. This study aimed at exploring the relationship of affect intensity variables with negative mood regulation (NMR) expectancy, their association with age and gender and examining the role of affect intensity and NMR expectancy as predictors of stress and well being in a community sample of Indian adults. The sample consisted of 206 participants aged between 20 and 60 years. Higher age was associated with higher NMR expectancy but lower positive affect intensity. Positive and negative affect intensity showed differential patterns of association with NMR expectancy. Higher negative affect intensity was associated with lower NMR expectancy whereas higher positive affect intensity was associated with higher NMR expectancy. Affect intensity and NMR expectancy variables jointly predicted 30-39% of variance in perceived stress and well being. Implications for further research are discussed.

    Background: Natural and man-made disasters affect people, communities, and health systems. Nurses play a key role in the health system and must be prepared for appropriate response in disasters. Objectives: This study was done to assess the current knowledge of nurses in emergency departments for disaster preparedness. Patients and Methods: This cross-sectional study was conducted on 110 emergency nurses working in teaching hospitals affiliated to Iran University of Medical Sciences, Tehran, Iran. A questionnaire was used to collect data and the data were then analyzed using descriptive and inferential statistics with SPSS software version 16.0. Results: Based on the findings, most of the participants (64.5%) were aged 30 - 39 years old. 84% of the cases were female and 97.3% had a bachelor’s degree. The average perceived knowledge of nurses was 2.43 ± 1.01. The nurses had the highest familiarity with triage and lowest knowledge in epidemiology and decision-making. Conclusions: Lack knowledge of nurses regarding response to disaster situations indicates inefficiencies in the current system. Therefore, it is recommended to organize more workshops, annual training courses, and maneuvers based on staff needs and formulate continuous education courses for nurses. PMID:26839868

    The Oxfordian La Manga Limestone (10-65 m) and overlying Auquilco Gypsum (315 m maximum thickness) crop out along the west flank of the Neuquen basin, Neuquen Province, Argentina (36/sup 0/40/sup 0/S lat.). The contact with the underlying Lotena Sandstone is gradational, and both formations are cut by the Late Jurassic Araucanian angular unconformity. Seven lithofacies have been identified within sections measured through the entire interval along the northeast to southwest trending, 30-km long Sierra de la Vaca Muerta ridge (38/sup 0/30'-39/sup 0/S). The La Manga Limestone is interpreted as a temperate ramp carbonate that developed over the Lotena Formation siliciclastic shelf. Interpretations of lithofacies from southwest to northeast are: behind-barrier subtidal lagoon with washovers; coral and red algae biostromes; ooid and peloid sand shoals; downslope wackestone and packstone mud mounds; and deep-water carbonate turbidites. A minor regression separates La Manga and Auquilco Formations. Lithofacies of the Auquilco Formation indicate a shallowing-up sequence comprised of initially deep (hundreds of meters) subaqueous evaporite deposition followed by shallow, subtidal carbonate peloidal and shell fragment grainstones and evaporites. Thickness of the subaqueous evaporite gives an order of magnitude estimate of Auquilco basin depths of a few hundred meters at most. The Neuquen basin has an intermediate proportion of carbonate in comparison to relatively carbonate-poor basins to the south and carbonate-rich basins to the north.

    Dissolved organic carbon (DOC) in the Pearl River system in Guangdong Province was fractioned by using XAD resins into humic substances and other fractions. The concentration and distribution of DOC, SUVA254, trihalomethanes formation potential (THMFP) and relationships between DOC and THMFP were analyzed. The 2-year study demonstrated that the DOC concentration of Pearl River ranged from 0.7 to 33.0 mg x L (-1). On the other hand, the trihalomethanes formation potential (THMFP) in Pearl River was 30.39-1 091.52 microg x L(-1), which showd a linear relationship with the DOC concentration. Spatially, the DOC concentration and THMFP increased downstream along each tributary; however, the humic substances mitigated to the opposite. During the chlorination, humic substances were the main precursors of disinfection by-products (generating 64.6% of THM) in Pearl River and the specific trihalomethanes formation potential (STHMFP) of humic substances was over 2 times higher as the other fractions. In addition, SUVA254 was proved to provide a reference indicator in testing the precursors of disinfection by-products.

    Surgical site infections (SSIs) are reported in lower frequencies in the developed countries than in the developing world. A prospective evaluation of risk factors in 285 patients undergoing abdominal surgery procedures in Zimbabwe was therefore undertaken. Overall infection rate was 26%. The age group 30-39 years had the highest number of dirty wounds and the highest rate of human immunodeficiency virus (HIV) infection. Multivariate regression analysis showed a correlation between wound class and SSI (P < 0·05). This was also noted for American Society of Anesthesiologists (ASA) score (P < 0·05). HIV-infected patients had 52% SSIs and non-infected patients had 26% (P < 0·05). Patients receiving blood transfusion had 51% SSIs and those not transfused had 17% (P < 0·01). Patients receiving pre- and intra-operative prophylactic antibiotics had 18% SSIs and those receiving postoperative administration had 37% (P < 0·01). Treatment ranged from dressings only in 11% to surgical intervention in 30% resulting in prolongation of median hospital stay from 8 to 18 days (P < 0·001). Mortality was 7%. High wound class, high ASA score, blood transfusion, HIV infection and delayed use of prophylactic antibiotics were risk factors for SSIs, resulting in surgical interventions, prolonged hospital stay and mortality.

    A retrospective cohort study was performed to evaluate the relationship of BMI to conversion rate in patients undergoing robotic surgery for endometrial cancer. Secondary outcomes were operative times, number of lymph nodes retrieved, and complications. Women with endometrial cancer scheduled for robotic surgery from September 2008 to September 2012 were included. Women were divided into three groups based on BMI, and conversion rates to laparotomy were compared. Descriptive and comparative analyses were performed among non-obese, obese, and morbidly obese women who completed robotic surgery. 298 women were scheduled for robotic surgery for endometrial carcinoma: 87 non-obese (BMI 19-29, μ 25.23), 110 obese (BMI 30-39, μ 34.21), and 101 morbidly obese (BMI 40-71, μ 47.38). Conversion to laparotomy occurred in 18 patients (6%), with no difference in conversion rate between BMI categories. Direct comparison between converted and completed robotic patients showed no significant differences in preoperative characteristics, except that patients who required conversion had a higher number of previous abdominal surgeries. Patients completing robotic surgery underwent node dissections at similar rates in all three BMI categories. Operating room time, but not surgical time, was increased in morbidly obese patients. There were no significant differences in complications, performance of lymphadenectomy, or lymph node yields between BMI categories. Increase in BMI was not associated with an increase in rate of conversion to laparotomy or complication rate in patients undergoing robotic surgery for endometrial carcinoma. Node dissections were pathologically equivalent between BMI categories.

    If a parasite is not detected during a survey, one of two explanations is possible: the parasite was truly absent or it was present but not detected. We fit occupancy models to account for imperfect detection when combing fleas (Siphonaptera) from black-tailed prairie dogs (Cynomys ludovicianus) during June-August 2012 in the Vermejo Park Ranch, New Mexico, USA. With the use of detection histories from combing events during monthly trapping sessions, we fit occupancy models for two flea species: Oropsylla hirusta (a prairie dog specialist) and Pulex simulans (a generalist). Detection probability was <100% for both species and about 21% lower for P. simulans. Pulex simulans may be especially difficult to detect because it is about half the size of O. hirusta. Monthly occupancy (prevalence) for P. simulans was estimated at 24% (June, 95% confidence interval = 19-30), 39% (July, 32-47), and 56% (August, 49-64) in new prairie dog colonies, and 43% (32-54), 61% (49-71), and 79% (70-87) in old colonies. These results suggest P. simulans can attain high prevalence on prairie dogs, especially in old colonies. If P. simulans is highly prevalent on prairie dogs, it may serve as a "bridge vector" between Cynomys and other mammalian hosts of the plague bacterium Yersinia pestis, and even function as a reservoir of Y. pestis between outbreaks.

    In this study, we aimed to determine whether anti-Müllerian hormone (AMH) levels vary between fertile and infertile populations and compare them with basal follicle-stimulating hormone (FSH) levels and antral follicle count (AFC). This was a prospective study that included 177 primarily infertile patients who underwent IVF treatment and 162 healthy fertile patients admitted to our clinic for benign diseases. FSH and AMH levels and the AFC of the infertile and fertile populations were compared between the age categories <30, 30-39 and ≥40. Correlations between AMH, basal FSH, and AFC with age were evaluated. AFC and AMH levels did not differ between the fertile and infertile groups in all age categories. AMH was inversely correlated with age in both the fertile and infertile populations. However, AFC revealed a stronger correlation with age in both the fertile and infertile populations compared with basal FSH and AMH. Age was positively correlated with basal FSH and inversely correlated with AMH and AFC. In conclusion, there was no significant difference between the fertile and infertile populations in terms of AMH or AFC. The decrease in ovarian reserve in infertile patients is directly related to age, not infertility.

    1990-01-01

    We studied cardiovascular responses to lower-body negative pressure (LBNP) following 1 hour (h) of 6 degrees head-down tilt to determine whether a redistribution of blood volume toward the central circulation modifies the subsequent response to orthostatic stress. Responses of 12 men, ages 30-39 years, were evaluated by electrocardiography, impedance cardiography, sphygmomanometry, and measurement of calf circumference. During the LBNP that followed head-down tilt--as compared with control LBNP (no preceding head-down tilt)--subjects had smaller stroke volume and cardiac output, greater total peripheral resistance, and less calf enlargement. These differences reflect differences in the variables immediately preceding LBNP. Magnitudes of the responses from pre-LBNP to each pressure stage of the LBNP procedure did not differ between protocols. Mean and diastolic arterial pressures were slightly elevated after LBNP-control, but they fell slightly during LBNP post-tilt. These cardiovascular responses to simulated gravitational stress following head-down tilt may reflect the manner in which adaptation to microgravity affects subsequent responses to orthostatic stress on return to Earth.

    Desert ants, foraging in cluttered semiarid environments, are thought to be visually guided along individual, habitual routes. While other navigational mechanisms (e.g. path integration) are well studied, the question of how ants extract reliable visual features from a complex visual scene is still largely open. This paper explores the assumption that the upper outline of ground objects formed against the sky, i.e. the skyline, provides sufficient information for visual navigation. We constructed a virtual model of the ant's environment. In the virtual environment, panoramic images were recorded and adapted to the resolution of the desert ant's complex eye. From these images either a skyline code or a pixel-based intensity code were extracted. Further, two homing algorithms were implemented, a modified version of the average landmark vector (ALV) model (Lambrinos et al. Robot Auton Syst 30:39-64, 2000) and a gradient ascent method. Results show less spatial aliasing for skyline coding and best homing performance for ALV homing based on skyline codes. This supports the assumption of skyline coding in visual homing of desert ants and allows novel approaches to technical outdoor navigation.

    Complications of childbirth and pregnancy are leading causes of death among women of reproductive age. Developing countries account for 99% of maternal deaths. The aim of this study was to explore levels, causes and risk factors associated with maternal mortality in rural Tanzania. Longitudinal data (2002-2006) from Rufiji HDSS was used where a total of 26 427 women aged 15-49 years were included in the study; 64 died and there were 15 548 live births. Cox proportional hazards regression was used to assess the risk factors associated with maternal deaths. MMR was 412 per 100 000 live births. The main causes of death were haemorrhage (28%), eclampsia (19%) and puerperal sepsis (8%). An increased risk of 154% for maternal death was found for women aged 30-39 versus 15-19 years (HR=2.54, 95% CI=1.001-6.445). Married women had a protective effect of 62% over unmarried ones (HR=0.38, 95% CI=0.176-0.839).

    Purpose: Partnership formation and dissolution rates are primary determinants of sexually transmitted infection (STI) transmission dynamics. Methods: The authors used data on persons' lifetime sexual experiences from a 2003-2004 random digit dialing survey of Seattle residents aged 18-39 years (N=1,194) to estimate age- and gender-specific partnership formation and dissolution rates. Partnership start and end dates were used to estimate participants' ages at the start of each partnership and partnership durations, and partnerships not enumerated in the survey were imputed. Results: Partnership formation peaked at age 19 at 0.9 (95% CI: 0.76, 1.04) partnerships per year and decreased to 0.1-0.2 after age 30 for women and peaked at age 20 at 1.4 (95% CI: 1.08, 1.64) and declined to 0.5 after age 30 for men. Nearly a quarter (23.7%) of partnerships ended within 1 week and over one-half (51.2%) ended within 12 weeks. Most (63.5%) individuals aged 30-39 had not formed a new sexual partnership in the past 3 years. Conclusion: A large proportion of the heterosexual population is no longer at substantial STI risk by their early 30s, but similar analyses among high-risk populations may give insight into reasons for the profound disparities in STI rates across populations.

    Background: Occupational accidents are a major point of concern in industries. The academic community should take the first step to address the long-neglected concerns of occupational safety. Objective: To assess the prevalence and pattern of occupational accidents. Materials and Methods: A record-based, cross-sectional study was done in three tile factories of Mangalore city, in Karnataka. A total of 416 workers were analyzed for the year 2004, and data regarding age, sex, job duration, type and nature of injury, body parts involved, and time of injury were collected in a prestructured proforma. Statistical Analysis: Proportions, Chi-square test, Univariate and Multivariate analysis. Results: The overall prevalence rate of accidents was found to be 18.5%. It was found that almost around 86% of the accidents had affected the limbs (upper limb 24.7%, lower limb 61%), around half (52%) of the injuries were contributed by superficial injuries, 40% of accidents were due to stepping/striking against objects and while handling. Hand tools and machinery in motion contributed to around 20% of the accidents. Accidents were more common among the younger age group and less-experienced workers. Multiple logistic regression analyses revealed that the age group of 30-39 years had an independent significant association with accidents (OR = 0.21, P = 0.04). Conclusion: Accidents in tile industries are an important occupational health problem in this area of the country. There is a need for proper safety training of the workers. PMID:20606926

    In order to describe accidents at work at a hospital in Northern Portugal and analyze their main impact in the period from 2008 to 2010, we conducted a retrospective cross-sectional study. The information was obtained from the notification records of accidents at work for 387 workers. The highest prevalence levels of accidents referred to superior health technician (56.1%), female workers (81.9%), in the age group 30-39 years (37.2%), with a secondary education degree (55.8%), working in shifts (72.4%) and in-patient services (35.9%). Needle pricks were the main cause (45.7%) and hands were the main injury location (37.5%). Wounds (32.6%) were the most frequent type of injury, followed by sprains and strains (23%). In total, 27.4% resulted in absence from work, with sprains and strains as the main reason. Preventive strategies should be adopted, aiming to promote these workers' health.

    In an epidemiological study of acute herniated lumbar intervertebral discs in the New Haven, Connecticut (U.S.A.), area, it was found that this condition was most likely to be diagnosed among persons in the age group 30-39 years, and that the most important risk factors among the variable considered in this study were driving of motor vehicles at or away from work, sedentary occupations, suburban residence, and previous full-term pregnancies. Variables for which there was some suggestion of an association but for which the evidence was inconclusive were the male sex, high social class among females, chronic cough and chronic bronchitis, participation in baseball, golf and bowling, the spring and fall seasons, and possibly lack of physical activity other than at work. No increase in risk for this condition was related to race, social class in males, smoking habits, participation in sports other than baseball, golf and bowling, weight or body bulk, recent episodes of emotional stress, pregnancies which were not full-term, and jobs involving lifting, pushing, pulling, or carrying.

    Orthostatic hypotension (OH), a proxy for sympathetic adrenergic failure, is the most incapacitating sign of autonomic failure. Orthostatic dizziness (OD) is known to be the most common symptom of OH. However, recent studies have demonstrated that 30-39 % of patients with OH experienced rotatory vertigo during upright posture (i.e., orthostatic vertigo, OV), which challenges the dogma that OH induces dizziness and not vertigo. A recent population-based study on spontaneously occurring OD across a wide age range showed that the one-year and lifetime prevalence of OD was 10.9 and 12.5 %, respectively. Approximately 83 % of patients with OD had at least one abnormal autonomic function test result. So far, 11 subtypes of OD have been proposed according to the pattern of autonomic dysfunction, and generalized autonomic failure of sympathetic adrenergic and parasympathetic cardiovagal functions was the most common type. Four different patterns of OH, such as classic, delayed, early, and transient type have been found in patients with OD. The head-up tilt test and Valsalva maneuver should be performed for a comprehensive evaluation of sympathetic adrenergic failure in patients with OD/OV. This review summarizes current advances in OH presenting OD/OV, with a particular focus on the autonomic dysfunction associated with OD.

    Early Pleistocene sediments bearing gastropod shells and pollen flora were found during coring at Jawornik (South Poland) at a depth interval of 54.30-39.00 m, beneath the oldest till of the Carpathians. Thirteen land-snail taxa identified in 55 samples of the core formed two molluscan assemblages. In the bottom part, typical cold-loving snails were found (e.g. Vallonia tenuilabris, Pupilla loessica, Vertigo genesii, Columella columella), whereas in the upper part only Semilimax kotulae was present. The succession of molluscan assemblages may suggest that at the site of deposition, after a phase of tundra, steppe-tundra or forest-steppe landscape with patches of wet habitats in cold climate, the climate became slightly milder but still cool, favourable to the spreading of boreal (coniferous) woodlands. Pollen analysis was performed only for the upper part of the profile. The pollen spectra, besides the Tertiary (Miocene) elements, contained sporomorphs common to the Tertiary and Quaternary floras. Among them, the highest percentages were noted for Pinus haploxylon t., P. diploxylon t., Picea, Quercus, Ericaceae, Betula, and Ulmus. The fact that the sediments with organic remains underlie the oldest Scandinavian till suggests that they are older than the oldest glacial unit of the South-Polish Complex (Narevian = Menapian, ~ 1.2 Ma).

    Interest in identifying pools of antibacterial-resistance genes has grown over the last decade, with veterinary antibiotics (VAs) receiving particular attention. In this paper, a mesoscale study aimed at evaluating the vertical transport of common VAs-namely, fluoroquinolones, tetracyclines, sulfonamides, and lincosamides in agricultural soil subjected to drip irrigation-was performed under greenhouse conditions. Accordingly, leachates of cropped and uncropped soil, amended with swine-slurry leading to 19-38 μg kg(-1) (dry mass) antibiotics in the soil, were analyzed over the course of the productive cycle of a lettuce (42 days) with three sampling campaigns (N = 24). High lincomycin (LCM) concentrations (30-39 μg L(-1)) were detected in the leachates collected from the swine-slurry-amended soil. The highest LCM mass recovered in the leachates (30.1 ± 1.63 %) was obtained from cropped experimental units. In addition, the LCM leaching constant and its leaching potential as obtained from the first-order model were higher in the leachates from the cropped experimental units. Lower concentrations of sulfadimethoxine were also detected in leachates and in soil. Enrofloxacin and oxytetracycline occurred only in soil, which is consistent with high soil interaction.

    To investigate the impact of interacting drugs on the dispensed doses of warfarin in the Swedish population. This was a retrospective, cross-sectional population based register study of patients being dispensed warfarin. Warfarin doses were estimated in different age groups, in men and women, and in patients using interacting drugs. The influence of interacting drugs on the dispensed warfarin dose was analyzed using multiple regression. All 143,729 patients dispensed warfarin were analyzed. The dispensed dose of warfarin was highest in patients 30-39 years old and decreased with age. Co-medication with carbamazepine, simvastatin, paracetamol, amiodarone, fluconazole, lactulose, or bezafibrate was associated with significant changes in dispensed warfarin doses, by +40%, -3.4%, -7.3%, -8.2%, -8.8%, -9.0%, and -9.7%, respectively. After adjustment for age and gender, sulfamethoxazole was also found to significantly alter the dispensed warfarin dose (-6.1%). We provide new support for the previous scarce evidence of interactions between warfarin and carbamazepine, bezafibrate, and lactulose. Initiation or discontinuation of bezafibrate or lactulose in a patient on warfarin should warrant close clinical monitoring. The marked increased warfarin requirement associated with carbamazepine use supports moving from a more conservative reactive towards a proactive strategy including preventive warfarin dose adjustments to avoid potential adverse effects.

    This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30-39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups. PMID:26423332

    Piroplasmosis in donkeys has been recognized as a serious problem of major economic importance, since the affected animals manifest loss of appetite and decreased working capacity. The present work is aimed at detecting infection or exposure of donkeys in São Paulo, Brazil to Theileria (T.) equi and Babesia (B.) caballi using molecular and serological approaches. EDTA-blood and serum samples were collected from 88 donkeys (Equus asinus). From 88 sampled donkeys, 65 (73.86%; 95% confidence interval, PI=63.41, 82.65) and 82 (93.2%; 95% confidence interval, PI=85.75, 97.46) animals showed IgG antibodies to T. equi (by ELISA) and B. caballi (by IFAT), respectively. Twenty-eight (31.81%; 95% confidence interval, PI=22.3, 42.61) and 18 (20.45%; 95% confidence interval, PI=12.6, 30.39) donkeys were positive to T. equi and B. caballi nested PCR assays, respectively. The results indicated that T. equi and B. caballi are prevalent among donkeys in Brazil.

    Leaching assessment on five heavy metals (copper, zinc, lead, nickel and cadmium) and two brominated flame retardants (BFRs), polybrominated diphenyl ethers (PBDEs) and tetrabromobisphenol A (TBBPA), from waste printed circuit boards (WPCBs) were conducted using various leaching methods. The mean leaching concentrations of copper were the highest in both toxicity characteristic leaching procedures (TCLP) and synthetic precipitation leaching procedures (SPLP) tests at 8.6 mg/L and 1.1mg/L, while only lead (6.2mg/L) exceeded the TCLP criteria and Chinese EPA regulatory limit (both 5.0mg/L). However, PBDEs and TBBPA were not detected in TCLP and SPLP tests. Then the BFRs leaching trends and potential leachabilities were further investigated in actual landfill leachates using a modified method. Leaching characteristics that fast-leaching initially followed by slow-desorption over time were generally observed. In landfill leachate tests, the highest leaching concentrations of PBDEs and TBBPA were determined at 30.39 and 12.27 μg/L. Meanwhile, the highest leaching rates were estimated to reach 0.08% and 1.00%, respectively, which were significantly influenced by the dissolved organic carbon contents of extracts, the hydrophobicities of target BFRs and the specific surface areas of WPCBs materials. These results proved that leaching from WPCBs was a significant emission source of BFRs in landfill and electronic waste recycling dumpsite. PMID:23291335

    Sixty Giardia duodenalis isolates from domestic (n=49) and wild (n=11) animals (dogs, cats, deers, wolves, raccoon dog and muskrat) were analysed by PCR-RFLP at glutamate dehydrogenase locus (gdh). The isolates were obtained from positive feces samples for Giardia cysts analysed by flotation technique with saturated sodium chloride solution (specific gravity 1.28). Three G. duodenalis genotypes were identified: C (10/60; 16.7%); D (42/60; 70.0%); and E (7/60; 11.7%). In dogs all three genotypes were found, with the following prevalences: 76.9% genotype D (30/39); 23.1% C (9/39); 2.6% genotype E (1/39). One dog was co-infected with C and D genotypes. In cats we identified only G. duodenalis genotype D. Wolves and raccoon dog harbored infection with G. duodenalis genotype D, deers with E type and muskrat C type. This is the first study regarding genotyping of G. duodenalis in cats and wild animals from Romania. To the best of our knowledge, this is the first report of assemblages E in roe deers; assemblage C in wolves and muskrat; and assemblage D in raccoon dog.

    Burnout syndrome is typified by three dimensions: emotional exhaustion (EE), depersonalization (DP) and low personal accomplishment (PS), and is prevalent among cancer care providers. The objective is to conduct a systematic review and meta-analysis of studies that evaluated the presence of burnout syndrome in professionals dedicated to the care of cancer patients. A search was conducted of the MEDLINE, LILACS and COCHRANE databases. Articles were selected that had used the Maslach questionnaire to assess burnout syndrome prevalence, had evaluated at least 35 subjects (including physicians), had at least a 20% questionnaire response rate, and that were published in English, Spanish or Portuguese. Ten studies (2375 participants) were included in this analysis. Severe involvement by any one of the three dimensions ranged from 8% to 51%. The overall prevalence of EE was found to be 36% [95% confidence interval (CI) (31-41)], while for DP this was 34% [95% CI (30-39)] and for PS 25% [95% CI (0.16-34)], demonstrating considerable heterogeneity across studies. The prevalence of burnout syndrome is elevated among cancer professionals throughout the world but varies substantially among studies. Further research is needed to better understand and prevent this syndrome. PMID:18771533

    66 mothers with children aged between 12-24 months were interviewed with a questionnaire in the industrial city of Lubhiana. The average age of the mothers ranged from 18-45 years. 66% were between 21-30; 39% had only 1 living child. 41% of the children were well nourished; were third degree malnourished. 91% were breast fed from birth. 30% mothers gave milk top feeds from birth; the additional milk was fresh buffalo (84%). The milk was boiled in 100% of cases and the water diluting the feeds was boiled in 46% cases. The water was added before the milk was boiled. 5% of mothers washed the bottle with water alone; 30% washed with an abrasive such as sand or ash. 49% never boiled the feeding bottle; 33% boiled the bottle once a day, and 18% boiled it before each feed. 23% claimed no incident or vomiting or diarrhoea, 26% admitted 1-2 incidents of vomiting or diarrhoea; 21% less than monthly bouts; 12% more than monthly bouts; and 18% admitted to weekly or more incidents of diarrhoea and vomiting. Deaths in rural India in the under age 5 group are attributed to malnutrition in 5% of cases.

    There is an increasing burden of obesity and obesity-related noncommunicable diseases in Gulf Cooperation Council countries, including Oman. This descriptive, epidemiological study assessed physical activity among 2977 Omani adults using a population-based household survey in 2008. Overall, 54.2% of men and 41.6% of women were physically active; the rate was higher in younger cohorts and varied significantly by region of residence. Physical activity related to the transportation (walking and cycling) domain was higher than in the leisure or work domains. Unmarried men aged 30-39 years were twice as likely to be physically active (OR 2.25) and unmarried women aged 40+ years were half as likely to be active (OR 0.58) than their married counterparts. Young women not working were less active (OR 0.18) than working women. Higher education was significantly associated with leisure activity for men aged 30+ years and women aged 40+ years. Further research to understand regional variations and to identify culturally appropriate strategies to promote physical activity is required. PMID:27180738

    Objective. To evaluate ego strengths, in the context of Erikson's framework, among adolescents and young adults diagnosed with opioid dependence as compared to non-drug using youth. Methods. Opioid dependent (n = 51) and non-drug using control (n = 31) youth completed the self-administered Psychosocial Inventory of Ego Strengths (PIES). The PIES assesses development in the framework of Erikson's ego strength stages. Multivariate linear regression modeling assessed the independent association of the primary covariate (opioid dependent versus control) as well as potential confounding variables (e.g., psychiatric comorbidities, intelligence) with total PIES score. Results. Mean total PIES score was significantly lower in opioid dependent youth (231.65 ± 30.39 opioid dependent versus 270.67 ± 30.06 control; p < 0.01). Evaluation of the PIES subscores found significant (p < 0.05) delays in all ego strength areas (hope, will, purpose, competence, fidelity, love, care, and wisdom). When adjusting for potential confounders, opioid dependence remained a significant (p < 0.001) independent predictor of total PIES score. Conclusion. Adolescents with opioid dependence demonstrated significant delays in ego strength development. A treatment approach acknowledging this delay may be needed in the counseling and treatment of adolescents with opioid dependence.

    Introduction In July 2014, Nigeria experienced an outbreak of Ebola virus disease following the introduction of the disease by an ill Liberian Traveler. The Government of Nigeria with the support of Technical and Development Partners responded quickly and effectively to contain the outbreak. The epidemiological profile of the outbreak that majorly affected two States in the country in terms of person, place and time characteristics of the cases identified is hereby described. Methods Using field investigation technique, all confirmed and probable cases were identified, line-listed and analysed using Microsoft Excel 2007 by persons, time and place. Results A total of 20 confirmed and probable cases; 16 in Lagos (including the index case from Liberia) and 4 in Port Harcourt were identified. The mean age was 39.5 ± 12.4 years with over 40% within the age group 30-39 years. The most frequent exposure type was direct physical contact in 70% of all cases and 73% among health care workers. The total case-fatality was 40%; higher among healthcare workers (46%) compared with non-healthcare workers (22%). The epidemic curve initially shows a typical common source outbreak, followed by a propagated pattern. Conclusion Investigation revealed the size and spread of the outbreak and provided information on the characteristics of persons, time and place. Enhanced surveillance measures, including contact tracing and follow- up proved very useful in early case detection and containment of the outbreak. PMID:26587177

    To investigate shoulder scoring systems used in Europe and North America and how outcomes might be classified after shoulder joint replacement. All research papers published in four major journals in 2012 and 2013 were reviewed for the shoulder scoring systems used in their published papers. A method of identifying how outcomes after shoulder arthroplasty might be used to categorize patients into fair, good, very good and excellent outcomes was explored using the outcome evaluations from patients treated in our own unit. A total of 174 research articles that were published in the four journals used some form of shoulder scoring system. The outcome from shoulder arthroplasty in our unit has been evaluated using the constant score (CS) and the oxford shoulder score and these scores have been used to evaluate individual patient outcomes. CSs of < 30 = unsatisfactory; 30-39 = fair; 40-59 = good; 60-69 = very good; and 70 and over = excellent. The most popular shoulder scoring systems in North America were Simple Shoulder Test and American shoulder and elbow surgeons standard shoulder assessment form score and in Europe CS, Oxford Shoulder Score and DASH score.

    If a parasite is not detected during a survey, one of two explanations is possible: the parasite was truly absent or it was present but not detected. We fit occupancy models to account for imperfect detection when combing fleas (Siphonaptera) from black-tailed prairie dogs (Cynomys ludovicianus) during June-August 2012 in the Vermejo Park Ranch, New Mexico, USA. With the use of detection histories from combing events during monthly trapping sessions, we fit occupancy models for two flea species: Oropsylla hirusta (a prairie dog specialist) and Pulex simulans (a generalist). Detection probability was <100% for both species and about 21% lower for P. simulans. Pulex simulans may be especially difficult to detect because it is about half the size of O. hirusta. Monthly occupancy (prevalence) for P. simulans was estimated at 24% (June, 95% confidence interval = 19-30), 39% (July, 32-47), and 56% (August, 49-64) in new prairie dog colonies, and 43% (32-54), 61% (49-71), and 79% (70-87) in old colonies. These results suggest P. simulans can attain high prevalence on prairie dogs, especially in old colonies. If P. simulans is highly prevalent on prairie dogs, it may serve as a "bridge vector" between Cynomys and other mammalian hosts of the plague bacterium Yersinia pestis, and even function as a reservoir of Y. pestis between outbreaks.

    The clinical records of 166 available vasectomy patients at the Fertility Control Clinic of the University of the Philippines, Philippines Medical Center were examined and in-depth interviews using the case study method were conducted with 10 vasectomy acceptors in an attempt to obtain the characteristics of vasectomy acceptors and to determine the persons most influential in the decision to accept vasectomy as well as the fears and problems relating to vasectomy. The demographic characteristics of age, educational achievement, occupation, residence, race, religion, marital status, total live births, and contraceptives used before vasectomy were gathered. The most probable acceptors of vasectomy are men in the 30-39 year age bracket, with high school education, an unskilled job, married, Catholic, father of 3-4 children, and wives who have used oral contraception. For 64% of the acceptors the reason for vasectomy was socioeconomic, according to clinic records. The in-depth interviews indicated the reasons for acceptance to be contraceptive failure and convenience. The mass media and "significant others" (such as friends; neighbors; associates; and the husband's manager) played a major role in the dissemination of vasectomy information. Husbands were the decision-makers in the family, particularly with regard to the choice of vasectomy. The nature of preoperative fears was related to possible side effects and the uncertain outcome of the procedure. The sexual relationship remained unchanged in regard to coital frequency, coital attitude, and behavior.

    Previous studies compared uptake by dendritic cells (DC) of 20, 40, 100, 200, 500, 1000, and 2000 nm beads in vivo. When beads were used as antigen carriers, bead size influenced antibody responses and induction of IFN-gamma-producing CD4 and CD8 T cells. Beads of 40-50 nm were taken up preferentially by DC and induced particularly strong immunity. Herein, we examine immunity induced by minute differences in nanobead size, specifically within a narrow viral-sized range (20, 40, 49, 67, 93, 101, and 123 nm), to see if bead carrier size influenced the induction of type 1 or type 2 cells as demonstrated by the production of IFN-gamma or IL-4. In vivo uptake by DC was assessed for selected sizes in this range. Responses to whole ovalbumin (OVA) or the OVA-derived CD8 T cell peptide epitope (SIINFEKL) were tested. After one immunization with beads-OVA, IFN-gamma responses to both OVA and SIINFEKL were significantly better with 40 and 49 nm beads than other sizes, while, in contrast, IL-4 responses to OVA were higher after immunization with OVA conjugated to larger beads (93, 101, and 123 nm). Thus IFN-gamma induction from CD8 T cells was limited to 40-49 nm beads, while CD4 T cell activation and IL-4 were induced by 93-123 nm beads-OVA. After two immunizations, there were comparable high levels of IFN-gamma produced with 40 and 49 beads and IL-4 reactivity was still higher for larger beads (93, 101, 123 nm). Production of IgG1 was seen across the full range of bead sizes, increasing after two immunizations. Since protection against respiratory syncytial virus (RSV) depends on strong IFN responses, while IL-4 responses are reported to cause asthma-like symptoms, immunization with RSV antigens on the 49 nm carrier beads could provide the basis for a suitable vaccine. When the 49 nm beads were conjugated to RSV proteins G88 (surface) or M2.1 (internal capsid), one immunization with G88 induced high levels of IFN-gamma and low levels of IL-4. IL-4 increased with two

    The possibility of an inverse relation between essential fatty acids in adipose tissue, in particular linoleic acid, and mortality from coronary heart disease was studied by a cross sectional survey of random population samples of apparently healthy men aged 40-49 from four European regions with differing mortality from coronary heart disease. The proportion of linoleic acid in adipose tissue was lowest in men from north Karelia, Finland, where mortality from coronary heart disease is highest, and highest in men from Italy, where mortality is lowest, with intermediate proportions in men from Scotland and south west Finland. Similar gradients were observed for the desaturation and elongation products dihomo-gamma-linolenic and arachidonic acid. The proportion of saturated fatty acids in adipose tissue was highest in Finland, intermediate in Scotland, and lowest in Italy. Italian men also had the highest proportion of oleate in their adipose tissue and the lowest proportion of myristoleate and palmitoleate. Finnish men were more obese and had a higher blood pressure. Serum cholesterol concentration was higher in north Karelia and south west Finland than in Scotland or Italy. High density lipoprotein (HDL) cholesterol concentrations reflected the regional differences in serum cholesterol, being higher in Finland and lower in Italy. The ratios of HDL cholesterol to total cholesterol, however, did not differ. The regional differences in linoleic acid in adipose tissue remained highly significant when the observed differences in other known risk factors for coronary heart disease among the four areas were taken into account by multivariate analysis. The gradients in proportions of polyunsaturated fatty acids probably reflect differences in dietary intake of linoleic acid. PMID:3087455

    In this paper we will report the results of nation-wide surveys on employee health conducted and published by the Ministry of Labour in 1982, 1987, and 1992. The subjects were approximately 20,000 employees in 1982, approximately 15,000 in 1987, and approximately 16,000 in 1992, from throughout Japan. Using the results of the surveys, we will show trends in the status of employee work-related stress, as well as trends in means of relaxation over the past decade. The percentage of employees with work-related stress among all subjects gradually increased as follows: 50.6% in 1982, 55.0% in 1987, and 57.3% in 1992. The percentage of employees with work-related stress increased remarkably from 1982 through 1992 among the following groups: the 50-59 age group in males; employees in the electricity, gas, heat and water-supply industries; those in the real estate industry; administrative and managerial workers; employees of large establishments with more than 5,000 employees; and employees performing shift work involving no night duty. The problem of "human relationships in the workplace" was associated with the increasing stress levels among 50-59-year-old males, 40-49-year-old females, employees of large establishments with more than 5,000 employees, those in the real estate industry, and service workers. In terms of means of relaxing to relieve fatigue and stress, employees tended to engage in active pursuits such as "eating out and shopping" and "driving and traveling" over the past decade. In 1992, on the other hand, 22.0% of males and 5.9% of females selected "smoking" as a means of relaxation. This shows the need for stress management in the workplace in order to prevent health problems related to smoking.

    Objective To evaluate the use of high-dose sequential chemotherapy in a Brazilian population. Methods High-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a Brazilian population. All patients (106 with high-grade non-Hodgkin lymphoma and 77 with Hodgkin's lymphoma) submitted to this treatment between 1998 and 2006 were analyzed. Chemotherapy consisted of the sequential administration of high-dose cyclophosphamide (4 or 7 g/m2) and granulocyte-colony stimulating factor (300 µg/day), followed by peripheral blood progenitor cell harvesting, administration of etoposide (2g/m2) and methotrexate (8 g/m2 only for Hodgkin's lymphoma) and autologous hematopoietic stem cell transplantation. Results At diagnosis, non-Hodgkin lymphoma patients had a median age of 45 (range: 8-65) years old, 78% had diffuse large B-cell lymphoma and 83% had stage III/IV disease. The Hodgkin's lymphoma patients had a median age of 23 (range: 7-68) years old, 64.9% had the nodular sclerosis subtype and 65% had stage III/IV disease. Nine Hodgkin's lymphoma patients (13%) and 10 (9%) non-Hodgkin lymphoma patients had some kind of cardiac toxicity. The overall survival, disease-free survival and progression-free survival in Hodgkin's lymphoma were 29%, 59% and 26%, respectively. In non-Hodgkin lymphoma, these values were 40%, 49% and 31%, respectively. High-dose cyclophosphamide-related mortality was 10% for Hodgkin's lymphoma and 5% for non-Hodgkin lymphoma patients. High-dose cyclophosphamide dosing had no impact on toxicity or survival for both groups. Conclusions Despite a greater prevalence of poor prognostic factors, our results are comparable to the literature. The incidence of secondary neoplasias is noteworthy. Our study suggests that this approach is efficient and feasible, regardless of toxicity-related mortality. PMID:23049359

    The Moessbauer spectrometer on Spirit measured the oxidation state of Fe, identified Fe-bearing phases, and measured relative abundances of Fe among those phases for surface materials on the plains and in the Columbia Hills of Gusev crater. Eight Fe-bearing phases were identified: olivine, pyroxene, ilmenite, magnetite, nanophase ferric oxide (npOx), hematite, goethite, and a Fe(3+)-sulfate. Adirondack basaltic rocks on the plains are nearly unaltered (Fe(3+)/Fe(sub T)<0.2) with Fe from olivine, pyroxene (Ol>Px), and minor npOx and magnetite. Columbia Hills basaltic rocks are nearly unaltered (Peace and Backstay), moderately altered (WoolyPatch, Wishstone, and Keystone), and pervasively altered (e.g., Clovis, Uchben, Watchtower, Keel, and Paros with Fe(3+)/Fe(sub T) approx.0.6-0.9). Fe from pyroxene is greater than Fe from olivine (Ol sometimes absent), and Fe(2+) from Ol+Px is 40-49% and 9-24% for moderately and pervasively altered materials, respectively. Ilmenite (Fe from Ilm approx.3-6%) is present in Backstay, Wishstone, Keystone, and related rocks along with magnetite (Fe from Mt approx. 10-15%). Remaining Fe is present as npOx, hematite, and goethite in variable proportions. Clovis has the highest goethite content (Fe from Gt=40%). Goethite (alpha-FeOOH) is mineralogical evidence for aqueous processes because it has structural hydroxide and is formed under aqueous conditions. Relatively unaltered basaltic soils (Fe(3+)/Fe(sub T) approx. 0.3) occur throughout Gusev crater (approx. 60-80% Fe from Ol+Px, approx. 10-30% from npOx, and approx. 10% from Mt). PasoRobles soil in the Columbia Hills has a unique occurrence of high concentrations of Fe(3+)-sulfate (approx. 65% of Fe). Magnetite is identified as a strongly magnetic phase in Martian soil and dust.

    AIM: To identify prognostic factors and to correlate APC mutations with clinical features, including extracolic manifestations. METHODS: One hundred thirty-five patients who underwent surgical procedures for familial adenomatous polyposis (FAP) were included. FAP was diagnosed when the number of adenomatous polyps was > 100. Data related to patient, extracoloic manifestations, cancer characteristics, operative procedure, follow up and surveillance were collected. APC mutation testing was performed in the 30 most recent patients. DNA was extracted from peripheral blood and polymerase chain reaction products using 31 primer pairs on APC gene were sequenced. A retrospective study was performed to investigate a causal relationship between prognosis and feature of patient. RESULTS: The mean age of the 51 patients with colorectal cancer (CRC) was older than that of those without CRC (30.5 vs 36.9, P = 0.002). Older individuals were more likely to have colon cancer at the time of FAP diagnosis [odds ratio, 4.75 (95%CI: 1.71-13.89) and 5.91(1.76-22.12) for 40-49 years and age > 50 vs age < 30). The number of confirmed deaths was 13 and the median age at death was 40 years (range, 27 to 85 years). Ten of the deaths (76.9%) were from CRC. Another cause of two cases of death were desmoid tumors (15.4%). Development of cancer on remnant rectal or ileal mucosa after surgery was not observed. The APC mutation testing revealed 23 pathogenic mutations and one likely pathogenic mutation, among which were four novel mutations. The correlation between mutational status and clinical manifestations was investigated. Mutations that could prodict poor prognosis were at codon 1309 which located on mutation cluster region, codon 1465 and codon 1507. CONCLUSION: Identification of APC mutations should aid in the diagnosis and counseling of family members in terms of early diagnosis and management of FAP. PMID:27158207

    The objective of this article is to illustrate user characteristics of a hospital's social media structure using analytics and user surveys. A 1-year retrospective analysis was conducted along with an Internet survey of users of the hospital's Facebook, Twitter, and blog. Of the survey respondents (n = 163), 95.7% are female and 4.3% are male; most are ages 50-59 years (31.5%) and 40-49 years (27.8%); and 93.2% are Caucasian. However, the hospital system database revealed 55% female and 37% minority population, respectively. Of the survey respondents, 61.4% reported having a bachelor's degree or higher, whereas only 11.7% reported having a high school degree/equivalent or lower. However, within the hospital patient databases, 93% of patients have a high school degree/equivalent or lower and only 3% have a bachelor's degree or higher in our women's services population. Social media were used to seek personal health information 68.7% (n = 112), to learn about hospital programming 27.6% (n = 45), and to seek family health information 25.2% (n = 41). Respondents younger than 49 years of age were more likely to seek personal health information using social media compared to those 50 years of age and older (p = .02). Respondents with a bachelor's degree or higher education were statistically less likely to search for physician information compared to those less educated individuals (p = .04). We conclude that social media may play an important role in personal health information, especially for young female respondents; however, the survey provides strong evidence that further research is needed to ensure that social network sites provided by hospitals are reaching the full spectrum of health system patients.

    AIM To determine the prevalence of colorectal neoplasia in average risk persons 40-59 years of age in Israel and to compare the results with other populations. METHODS We reviewed the results of asymptomatic average-risk subjects, aged 40 to 59 years, undergoing their first screening colonoscopy between April 1994 and January 2014. The detection rates of adenoma, advanced adenoma (AA) and colorectal cancer (CRC) were determined in the 40’s and 50’s age groups by gender. The prevalence of lesions was compared between age groups. After meticulous review of the literature, these results were compared to published studies addressing the prevalence of colorectal neoplasia in similar patient groups, in a variety of geographical locations. RESULTS We included first screening colonoscopy results of 1750 individuals. The prevalence of adenomas, AA and CRC was 8.3%, 1.0% and 0.2% in the 40-49 age group and 13.7%, 2.4% and 0.2% in the 50-59 age group, respectively. Age-dependent differences in adenoma and AA rates were significant only among men (P < 0.005). Literature review disclosed 17 relevant studies. As expected, in both Asian and Western populations, the risks for overall adenoma and advanced adenoma was significantly higher in the 50's age group as compared to the 40's age group in a similar fashion. The result of the current study were similar to previous studies on Western populations. A substantially higher rate of adenoma, was observed in studies conducted among Asian populations in both age groups. CONCLUSION The higher rate of colorectal neoplasia in Asian populations requires further investigation and reconsideration as to the starting age of screening in that population.

    Intervertebral disc degeneration (IDD) is one of the most common skeletal disorders, yet few data are available in Asian populations. We sought to assess the prevalence and pattern of radiographic IDD in a Vietnamese population. This population-based cross-sectional investigation involved 170 men and 488 women aged ≥40 years, who were randomly sampled from the Ho Chi Minh City (Vietnam). Anthropometric data, clinical history and self-reported back and neck pain were ascertained by a questionnaire. Plain radiographs (from the cervical spine, thoracic spine to the lumbar spine) were examined for the presence of disc space narrowing and/or osteophytosis using the Kellgren-Lawrence (KL) grading system. The presence of radiographic IDD was defined if the KL grade was 2 or greater in at least one disc. The prevalence of radiographic IDD was 62.4% (n = 106) in men and 54.7% (n = 267) in women. The most frequently affected site was the lumbar spine with prevalence being 50.6 and 43.2% in men and women, respectively. The prevalence of IDD increased with advancing age: 18.8% among those aged 40-49 years, and increased to 83.4% in those aged ≥60 years. Self-reported neck pain and lower back pain were found in 30 and 44% of individuals, respectively. There was no statistically significant association between self-reported neck pain and cervical spine OA. These data suggest that radiographic IDD is highly prevalent in the Vietnamese population, and that self-reported back pain is not a sensitive indicator of IDD.

    Background The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria. Methods Patients (N = 487, 64.7% male, age 60.9 ± 12.5 SD years) after myocardial infarction, with or without percutaneous interventions, coronary artery bypass grafting or valve surgery underwent inpatient cardiac rehabilitation and were included in this long-term observational study (two years follow-up). HRQL was measured with both the MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]. Results All MacNew scale scores improved significantly (p < 0.001) and exceeded the minimal important difference (0.5 MacNew points) by the end of rehabilitation. Although all MacNew scale scores deteriorated significantly over the two year follow-up period (p < .001), all MacNew scale scores still remained significantly higher than the pre-rehabilitation values. The mean improvement after two years in the MacNew social scale exceeded the minimal important difference while MacNew scale scores greater than the minimal important difference were reported by 40-49% of the patients. Two years after rehabilitation the mean improvement in the EQ-5D Visual Analogue Scale score was not significant with no significant change in the proportion of patients reporting problems at this time. Conclusion These findings provide a first indication that two years following inpatient cardiac rehabilitation in Austria, the long-term improvements in HRQL are statistically significant and clinically relevant for almost 50% of the patients. Future controlled randomized trials comparing different cardiac rehabilitation programs are needed. PMID:19995445

    Coconut copra from West coast tall variety, cultivated in Kerala, India, was subjected to aqueous and solvent extractions (using n-hexane). Additionally, oil was extracted from the copra in Soxhlet assembly using petroleum ether (b.p. 60-80°C). Physicochemical and phytochemical analyses were conducted for the extracts and the oil, with commercial coconut oil as the experimental control. The physicochemical analyses showed that the aqueous extract of copra was milky-white in color with a sweet odor, while the solvent extract was pale yellow and odorless. The commercial oil had 0.08 ± 0.02% oleic acid and a TOTOX value of 7.73 ± 0.78, lower than the Soxhlet extracted oil. Among all the extracts and oils, best phytochemical properties, antioxidant activity (DPPH activity, IC50 value 0.04 ± 0.01 mg/mL), total phenol (0.96 ± 0.04 mg gallic acid eq./g dry copra), reducing power (40.49 ± 1.84 mg BHT eq./g dry copra), and anti-inflammatory activity (NO activity, IC50  value 0.77 ± 0.06 mg/mL) were obtained in the commercial coconut oil, followed by the Soxhlet extracted oil, aqueous extract, and solvent extract. Fatty acid composition analyses showed mainly medium chain fatty acids in the copra oil with lauric acid as the predominant fatty acid (51.88% and 44.84% in Soxhlet extracted and commercial oils, resp.).

    In the Netherlands, routine mammography screening starts at age 50. This starting age may have to be reconsidered because of the increasing breast cancer incidence among women aged 40 to 49 and the recent implementation of digital mammography. We assessed the cost-effectiveness of digital mammography screening that starts between age 40 and 49, using a microsimulation model. Women were screened before age 50, in addition to the current programme (biennial 50-74). Screening strategies varied in starting age (between 40 and 50) and frequency (annual or biennial). The numbers of breast cancers diagnosed, life-years gained (LYG) and breast cancer deaths averted were predicted and incremental cost-effectiveness ratios (ICERs) were calculated to compare screening scenarios. Biennial screening from age 50 to 74 (current strategy) was estimated to gain 157 life years per 1,000 women with lifelong follow-up, compared to a situation without screening, and cost €3,376/LYG (3.5% discounted). Additional screening increased the number of LYG, compared to no screening, ranging from 168 to 242. The costs to generate one additional LYG (i.e., ICER), comparing a screening strategy to the less intensive alternative, were estimated at €5,329 (biennial 48-74 vs. current strategy), €7,628 (biennial 45-74 vs. biennial 48-74), €10,826 (biennial 40-74 vs. biennial 45-74) and €18,759 (annual 40-49 + biennial 50-74 vs. biennial 40-74). Other strategies (49 + biennial 50-74 and annual 45-49 + biennial 50-74) resulted in less favourable ICERs. These findings show that extending the Dutch screening programme by screening between age 40 and 49 is cost-effective, particularly for biennial strategies.

    Lymphatic filariasis (LF) caused by the nematode Wuchereria bancrofti is a major public health concern in endemic communities worldwide. Among tropical diseases it is second to malaria in terms of disability adjusted life years. The Nigerian LF elimination programme has been slated for 2015. Currently, there is paucity of published data on the problem in rural Ebonyi State. This survey was conducted in six rural communities of southwestern Ebonyi State to assess its prevalence among the population and provide baseline data for incorporation into the national LF elimination programme. Immunochromatographic card test (ICT) for detecting circulating filarial antigen (CFA) using whole blood and overt clinical manifestations (lymphoedema and hydrocoele) were used as epidemiological tools. All the studied communities were endemic for active bancroftian filariasis. Of the 600 randomly selected subjects aged ≥10 years, an overall prevalence of 23.50% was established (range, 17.00 - 30.00%). Overall, the antigenaemic prevalence was similar; there was a trend of slightly higher prevalence in males (24.34%) than females (22.39%). The between-gender prevalence difference was not statistically significant (χ² = 8.16, df = 1, p = 0.05) based on CFA positivity. Antigenaemia prevalence was age-dependent, increased exponentially and peaked at 20.57% in subjects in the 40-49 years age category. Lymphoedema and hydrocoele attributable to W. bancrofti were observed in 4.05% of subjects examined. Generally, hydrocoele was observed in 1.69% males, whereas lymphoedema was presented by 2.36% (1.35% females; 1.01% males) of studied population. None of the male subjects had both the two clinical features. Results of this study showed that W. bancrofti infection is widespread in southwestern Ebonyi State, Nigeria, and is a major health issue. There is a need for mass mobilization, mass education and community involvement in sustained intervention programme toward lymphatic filariasis

  10. At what age should screening mammography be recommended for Asian women?

    Although regular screening mammography has been suggested to be associated with improvements in the relative survival of breast cancer in recent years, the appropriate age to start screening mammography remains controversial. In November 2009, the United States Preventive Service Task Force published updated guidelines for breast cancer, which no longer support routine screening mammography for women aged 40-49 years, but instead, defer the choice of screening in that age group to the patient and physician. The age to begin screening differs between guidelines, including those from the Task Force, the American Cancer Society and the World Health Organization. It remains unclear how this discrepancy impacts patient survival, especially among certain subpopulations. Although the biological characteristics of breast cancer and peak age of incidence differ among different ethnic populations, there have been few reports that evaluate the starting age for screening mammography based on ethnicity. Here, we discuss the benefits and harm of screening mammography in the fifth decade, and re-evaluate the starting age for screening mammography taking ethnicity into account, focusing on the Asian population. Breast cancer incidence peaked in the fifth decade in Asian women, which has been thought to be due to a combination of biological and environmental factors. Previous reports suggest that Asian women in their 40s may receive more benefit and less harm from screening mammography than the age-matched non-Asian US population. Therefore, starting screening mammography at age 40 may be beneficial for women of Asian ethnicity in well-resourced countries, such as Japanese women who reside in Japan.

    Use of indoor tanning devices increases risk of cutaneous malignant melanoma, but the association with risk of squamous cell carcinoma (SCC) of the skin is unclear. Cohort studies of SCC risk are rare and we aimed to assess the association between SCC risk and host characteristics, sun exposure, and indoor tanning in a population-based cohort of Norwegian and Swedish women conjunctly with SCC incidence data from national cancer registries. Host characteristics and exposure to sun and indoor tanning devices before 50-years old were recorded by questionnaire at inclusion (30-50 years) in 1991/92. Multivariable relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Poisson regression. During follow-up of 106,548 women through December 2009, SCC was diagnosed in 141 women. Skin sensitivity to acute sun exposure was the most important pigmentation characteristic (RR = 2.73, 95% CI 1.47-5.05, for red with pain/red with pain and blisters versus brown). We found no consistent associations with sunburns and bathing vacations in the first five age decades, but a significant positive trend for bathing vacations summarized over ages 10-49 years (Ptrend  = 0.02). We also found significantly increased risks of SCC following indoor tanning at age 40-49 years (RR = 2.17, 95% CI 1.29-3.67, for ≥ 1 time/month versus never) and indoor tanning summarized over ages 10-49 years (Ptrend  = 0.001). RR for ever versus never use of indoor tanning over ages 10-49 years was 1.93 (95% CI 1.27-2.95). Propensity to burn was an important host characteristic, and bathing vacations and indoor tanning summarized over ages 10-49 years increased SCC risk.

    For healthy women, without malignancies in their personal histories, a positive family history for breast cancer is the single indication for individual breast surveillance outside the population screening. Management of women is based on individual risk assessment. A cumulative risk of 20% and more, as a result of a positive family history, will in practice be an indication for breast surveillance. This threshold is not evidence-based yet, nor are data available on the benefits of this surveillance efficacy. When a personal cumulative risk of more than 30% exists to develop breast cancer, a consultation with a clinical geneticist involved in a family cancer clinic should be offered. Surveillance of women with a high-risk cumulative risk should preferably be included in a prospective study design. Only in this way will data about compliance and the estimates of different ways of surveillance become available. There is no convincing evidence that population screening for women aged 40-49 years does lead to important mortality reduction in combination with a good balance between pros and cons for the women involved. Women in the age category 50-75 years, with breast cancer in their personal histories, who are not followed anymore, should be informed by their specialist about participating (again) in the population breast screening. There is no evidence of mortality reduction as a result of breast self-examination nor of palpation performed by a physician. However, awareness of the own body can be useful for early recognition of breast abnormalities; it may reduce the delay between the first recognizable symptom and the subsequently initiated therapy.

    Rationale Adverse social experience in adolescence causes reduced medial prefrontal cortex (mPFC) dopamine (DA) and associated behavioral deficits in early adulthood. Objective To determine whether mPFC DA hypofunction following social stress is specific to adolescent experience, and if this results from stress-induced DA D2 receptor activation. Materials and Methods Male rats exposed to repeated social defeat during adolescence or adulthood had mPFC DA activity sampled 17 days later. Separate experiments used freely-moving microdialysis to measure mPFC DA release in response to adolescent defeat exposure. At P40, 49 and 56 mPFC DA turnover was assessed to identify when DA activity decreased in relation to the adolescent defeat experience. Finally, non-defeated adolescent rats received repeated intra-mPFC infusions of the D2 receptor agonist quinpirole, while another adolescent group received intra-mPFC infusions of the D2 antagonist amisulpride before defeat exposure. Results Long-term decreases or increases in mPFC DA turnover were observed following adolescent or adult defeat, respectively. Adolescent defeat exposure elicits sustained increases in mPFC DA release, and DA turnover remains elevated beyond the stress experience before declining to levels below normal at P56. Activation of mPFC D2 receptors in non-defeated adolescents decreases DA activity in a similar manner to that caused by adolescent defeat, while defeat-induced reductions in mPFC DA activity are prevented by D2 receptor blockade. Conclusions Both the developing and mature PFC DA systems are vulnerable to social stress, but only adolescent defeat causes DA hypofunction. This appears to result in part from stress-induced activation of mPFC D2 autoreceptors. PMID:24271009

  14. Curative and population medicine: bridging the great divide.

    There are gaps in understanding between practicing physicians (curative medicine) and those trained in public health and epidemiology (population medicine). In the last century, these groups were closer, as physicians played a role in public health, sanitation and in the prevention of the spreading of infection. However, with the recent extraordinary successes of the biomedical model in explaining disease, and the ensuing explosion of remarkable - and expensive - medical procedures and treatments, public health, preventive medicine and the population approach in general have been overshadowed. In this essay, I try to explain how the training of physicians and the daily care of patients may hinder their appreciation of the population model. For instance, for many of the myriad decisions involved in patient care in daily practice, there is little evidence, population derived or otherwise. What little evidence there is may be dominated by personal experiences, opinions and values. Additionally, the statistical and epidemiologic approach necessary for the maintenance of health and prevention of illness may not be valued by practitioners whose training and focus is on treating sick people one by one. To illustrate these disparities in understanding, examples are given from the NIH Consensus Conference on mammography screening for women aged 40-49, and from the use of science in the courtroom in adjudicating toxic tort cases. Understanding population medicine requires an appreciation of the concepts of chance, probability and statistics and of epidemiologic principles, difficult areas for many - including the general public. These topics play a small to nonexistent role in the formal training of most physicians. Some closing of the gap in understanding may be occurring. It is hoped this essay will help. PMID:10202265

    Lymphatic filariasis (LF) caused by the nematode Wuchereria bancrofti is a major public health concern in endemic communities worldwide. Among tropical diseases it is second to malaria in terms of disability adjusted life years. The Nigerian LF elimination programme has been slated for 2015. Currently, there is paucity of published data on the problem in rural Ebonyi State. This survey was conducted in six rural communities of southwestern Ebonyi State to assess its prevalence among the population and provide baseline data for incorporation into the national LF elimination programme. Immunochromatographic card test (ICT) for detecting circulating filarial antigen (CFA) using whole blood and overt clinical manifestations (lymphoedema and hydrocoele) were used as epidemiological tools. All the studied communities were endemic for active bancroftian filariasis. Of the 600 randomly selected subjects aged ≥10 years, an overall prevalence of 23.50% was established (range, 17.00 - 30.00%). Overall, the antigenaemic prevalence was similar; there was a trend of slightly higher prevalence in males (24.34%) than females (22.39%). The between-gender prevalence difference was not statistically significant (χ² = 8.16, df = 1, p = 0.05) based on CFA positivity. Antigenaemia prevalence was age-dependent, increased exponentially and peaked at 20.57% in subjects in the 40-49 years age category. Lymphoedema and hydrocoele attributable to W. bancrofti were observed in 4.05% of subjects examined. Generally, hydrocoele was observed in 1.69% males, whereas lymphoedema was presented by 2.36% (1.35% females; 1.01% males) of studied population. None of the male subjects had both the two clinical features. Results of this study showed that W. bancrofti infection is widespread in southwestern Ebonyi State, Nigeria, and is a major health issue. There is a need for mass mobilization, mass education and community involvement in sustained intervention programme toward lymphatic filariasis

    AIM To determine the prevalence of colorectal neoplasia in average risk persons 40-59 years of age in Israel and to compare the results with other populations. METHODS We reviewed the results of asymptomatic average-risk subjects, aged 40 to 59 years, undergoing their first screening colonoscopy between April 1994 and January 2014. The detection rates of adenoma, advanced adenoma (AA) and colorectal cancer (CRC) were determined in the 40’s and 50’s age groups by gender. The prevalence of lesions was compared between age groups. After meticulous review of the literature, these results were compared to published studies addressing the prevalence of colorectal neoplasia in similar patient groups, in a variety of geographical locations. RESULTS We included first screening colonoscopy results of 1750 individuals. The prevalence of adenomas, AA and CRC was 8.3%, 1.0% and 0.2% in the 40-49 age group and 13.7%, 2.4% and 0.2% in the 50-59 age group, respectively. Age-dependent differences in adenoma and AA rates were significant only among men (P < 0.005). Literature review disclosed 17 relevant studies. As expected, in both Asian and Western populations, the risks for overall adenoma and advanced adenoma was significantly higher in the 50's age group as compared to the 40's age group in a similar fashion. The result of the current study were similar to previous studies on Western populations. A substantially higher rate of adenoma, was observed in studies conducted among Asian populations in both age groups. CONCLUSION The higher rate of colorectal neoplasia in Asian populations requires further investigation and reconsideration as to the starting age of screening in that population. PMID:27621582

    The biliary and renal excretion of acetaminophen and its metabolites over 8 hr was determined in rats exposed to diethyl ether by inhalation for 1 hr. Additional rats were anesthetized with urethane (1 g/kg ip) while control animals were conscious throughout the experiment (surgery was performed under hexobarbital narcosis: 150 mg/kg ip; 30-min duration). The concentration of UDP-glucuronic acid was decreased 80% in livers from ether-anesthetized rats but was not reduced in urethane-treated animals when compared to that in control rats. The concentration of reduced glutathione was not affected by either urethane or diethyl ether. Basal bile flow was not altered by the anesthetic agents. Bile flow rate after acetaminophen injection (100 mg/kg iv) was increased slightly over basal levels for 2 hr in hexobarbital-treated control rats, was unaltered in urethane-anesthetized animals, and was decreased throughout the 8-hr experiment in rats exposed to diethyl ether for 1 hr. In control and urethane-anesthetized animals, approximately 30-35% of the total acetaminophen dose (100 mg/kg iv) was excreted into bile in 8 hr, while only 16% was excreted in rats anesthetized with diethyl ether. Urinary elimination (60-70% of the dose) was not altered by exposure to ether. Separation of metabolites by reverse-phase high-pressure liquid chromatography showed that ether decreased the biliary elimination of unchanged acetaminophen and its glucuronide, sulfate, and glutathione conjugates by 47, 40, 49, and 73%, respectively, as compared to control rats. Excretion of unchanged acetaminophen and the glutathione conjugate into bile was depressed in urethane-anesthetized animals by 45 and 66%, respectively, whereas elimination of the glucuronide and sulfate conjugates was increased by 27 and 50%, respectively. These results indicate that biliary excretion is influenced by the anesthetic agent and that diethyl ether depresses conjugation with sulfate and glutathione as well as glucuronic

  18. Variation of benefits and harms of breast cancer screening with age.

    PubMed

    Harris, R

    1997-01-01

    The critical issue in deciding whether to recommend breast cancer screening for women in their forties is to determine whether potential benefits are substantially greater than potential harms. Recent evidence from randomized clinical trials makes it likely that, after 10-12 years of follow-up, there is a real benefit from screening women ages 40-49, on the order of a 15-20% reduction in the relative risk of breast cancer death. This relative risk reduction translates into an absolute risk reduction of 1-2 women whose lives are extended from screening 1,000 women in their forties annually for 10 years (i.e., about one life extended per 5,000 mammograms). The absolute benefit of screening increases with age. Evidence about potential harms is less well established, but it is compelling that there are 15-40 times as many false positive as true positive mammograms (depending on the patient's age), and that at least some of the women with false positive mammograms have ongoing psychological distress as a result. Some 30% of all women who are screened annually during their forties will have at least one false positive mammogram and this probability likely decreases with advancing age. If the balance between benefits and harms is judged to be a "close call" for women in their forties, a blanket recommendation for all is inappropriate. Instead, each woman in her forties should be helped to understand the pros and cons of screening, to clarify her own values, and to consider with her primary care physician what decision would be best for her.

    Background The Mean Heart Rate (MHR) tends to decrease with age. When adjusted for gender and diseases, the magnitude of this effect is unclear. Objective To analyze the MHR in a stratified sample of active and functionally independent individuals. Methods A total of 1,172 patients aged ≥ 40 years underwent Holter monitoring and were stratified by age group: 1 = 40-49, 2 = 50-59, 3 = 60-69, 4 = 70-79, 5 = ≥ 80 years. The MHR was evaluated according to age and gender, adjusted for Hypertension (SAH), dyslipidemia and non-insulin dependent diabetes mellitus (NIDDM). Several models of ANOVA, correlation and linear regression were employed. A two-tailed p value <0.05 was considered significant (95% CI). Results The MHR tended to decrease with the age range: 1 = 77.20 ± 7.10; 2 = 76.66 ± 7.07; 3 = 74.02 ± 7.46; 4 = 72.93 ± 7.35; 5 = 73.41 ± 7.98 (p < 0.001). Women showed a correlation with higher MHR (p <0.001). In the ANOVA and regression models, age and gender were predictors (p < 0.001). However, R2 and ETA2 < 0.10, as well as discrete standardized beta coefficients indicated reduced effect. Dyslipidemia, hypertension and DM did not influence the findings. Conclusion The MHR decreased with age. Women had higher values of MHR, regardless of the age group. Correlations between MHR and age or gender, albeit significant, showed the effect magnitude had little statistical relevance. The prevalence of SAH, dyslipidemia and diabetes mellitus did not influence the results. PMID:24029962

    Many interventions demonstrate success in adapting the duration of intravenous antibiotic therapy, but few studies have been conducted in developing countries. The aim of this study was to evaluate the effectiveness of an intervention in the induction of early discontinuation of intravenous antimicrobial therapy and/or its switch to oral therapy. The study employed a before-after intervention design that consisted of displaying a message in the computerized prescription on the third day and suspension of the prescription on the fifth day of intravenous antimicrobial therapy. A total of 465 patients were followed during the control period (CP) and 440 in the intervention period (IP). The intravenous therapy was switched to oral therapy for 11 (2.4%) patients during the CP and 25 (5.7%) in the IP (p=0.011), and was discontinued for 82 (17.6%) patients during the CP and 106 (24.1%) in the IP (p=0.017). During the IP there was a significant increase of patients who had their antimicrobial treatment discontinued before the seventh day of intravenous treatment, 37.40% (49/131) in the IP and 16.13% (15/93) in the CP (p=0.0005). The duration of intravenous antimicrobial therapy decreased by one day, but it was not significant (p=0.136). It is concluded that the proposed intervention is effective in promoting the early discontinuation of antimicrobial treatment and/or switch to oral therapy. As long as a computerized system for prescription already exists, it is easy and inexpensive to be implemented, especially in hospitals in developing countries.

    This study aimed to determine if there was an association between the implementation of smoking regulation policies and the urine cotinine concentrations of Korean non-smokers. The subjects of this study were 4612 non-smoking Korean citizens (aged 19 or older) selected from the first stage of the Korean National Environmental Health Survey conducted by the National Institute of Environmental Research from 2009 to 2011. Cotinine concentrations in urine were measured by GC-MS (limit of detection: 0.05 ng/mL). Changes in the urine cotinine concentration were analyzed using a weighted general linear model and linear regression and values were shown as geometric mean (GM). The GM urine cotinine concentration decreased over time (2.92 ng/mL in 2009, 1.93 ng/mL in 2010, and 1.25 ng/mL in 2011). The total decrease in the subjects' urine cotinine concentration between 2009 and 2011 was 2.79 ng/mL, representing a relative decrease of 54.7%. The decrease in GM urine cotinine concentration in each subgroup ranged from 2.17 ng/mL to 3.29 ng/mL (relative decreases of 46.4% and 62.8%, respectively), with the largest absolute reductions in subjects in the following groups: females, aged 40-49 years, detached residence type, no alcohol consumption, employed, secondhand smoke exposure. All groups had negative regression coefficients, all of which were significant (p < 0.001). Our results provide indirect indicators of the effectiveness of smoking regulation policies including the revision of the National Health Promotion Act in Korea.

    Aim To compare barriers against mammography screening (MS) in socioeconomically the most and the least developed cities in a developing country, Turkey. Methods We compared two population-based survey studies investigating barriers against MS in women aged 40-69 years and living in the lowest socioeconomic status (SES) city (Mus) and the highest SES city (Istanbul/Bahcesehir). Results In Mus 2,054 and in Bahcesehir 908 women were surveyed. MS rate was higher in Bahcesehir (49% vs. 35%, p<0.001). Being younger than 50 years old and having no insurance were barriers against MS in Mus. Being older than 60 years of age, widowhood, being illiterate, unemployment, a monthly income lower than the hunger threshold and limited insurance coverage were barriers against MS in Bahcesehir. Both in Mus and in Bahcesehir women not reading the daily newspaper and not making annual gynecology visits had lower MS rates. Both in Mus and in Bahcesehir audiovisual media was the most common source of information about breast cancer (BC). Women, who had a chance to be informed about BC by their doctors, had a higher MS rate. Being knowledgeable about BC being the most common cancer in females increased MS rates in both cities, while a false belief of MS exposing to unnecessary radiation decreased MS rates in both cities. Conclusion Both in high and low SES populations more efforts should be given to influence women with low educational level, low-income level, and having no/limited insurance, while designing BC awareness programs. Low SES populations women being in 40-49 years age interval, in high SES populations being in 60-69 years age interval, and widowhood were SES-specific barriers and should be taken into consideration. Audiovisual media should be used efficiently to educate women on BC. Physicians from all specialties should not miss the chance to refer their patients to MS. PMID:27555988

    Immune dysregulation and altered T-cell hemostasis play important roles in the pathogenesis of myelodysplastic syndromes (MDS). Recent studies suggest an increased risk of MDS among patients with autoimmune diseases. Here, we investigated the prevalence of autoimmune diseases among MDS patients, comparing characteristics and outcomes in those with and without autoimmune diseases. From our study group of 1408 MDS patients, 391 (28%) had autoimmune disease, with hypothyroidism being the most common type, accounting for 44% (n = 171) of patients (12% among all MDS patients analyzed). Other autoimmune diseases with ≥5% prevalence included idiopathic thrombocytopenic purpura in 12% (n = 46), rheumatoid arthritis in 10% (n = 41), and psoriasis in 7% (n = 28) of patients. Autoimmune diseases were more common in female MDS patients, those with RA or RCMD WHO subtype, and those who were less dependent on red blood cell transfusion. Median overall survival (OS) was 60 months (95% CI, 50-70) for patients with autoimmune diseases versus 45 months (95% CI, 40-49) for those without (log-rank test, P = 0.006). By multivariate analysis adjusting for revised IPSS and age >60 years, autoimmune diseases were a statistically significant independent factor for OS (HR 0.78; 95% CI, 0.66-0.92; P = 0.004). The rate of acute myeloid leukemia (AML) transformation was 23% (n = 89) in MDS patients with autoimmune disease versus 30% (n = 301) in those without (P = 0.011). Patient groups did not differ in response to azacitidine or lenalidomide treatment. Autoimmune diseases are prevalent among MDS patients. MDS patients with autoimmune diseases have better OS and less AML transformation. PMID:26875020

    In the photosynthetic electron transfer (ET) chain, two electrons transfer from photosystem I to the flavin-dependent ferredoxin-NADP(+) reductase (FNR) via two sequential independent ferredoxin (Fd) electron carriers. In some algae and cyanobacteria (as Anabaena), under low iron conditions, flavodoxin (Fld) replaces Fd as single electron carrier. Extensive mutational studies have characterized the protein-protein interaction in FNR/Fd and FNR/Fld complexes. Interestingly, even though Fd and Fld share the interaction site on FNR, individual residues on FNR do not participate to the same extent in the interaction with each of the protein partners, pointing to different electron transfer mechanisms. Despite of extensive mutational studies, only FNR/Fd X-ray structures from Anabaena and maize have been solved; structural data for FNR/Fld remains elusive. Here, we present a multiscale modelling approach including coarse-grained and all-atom protein-protein docking, the QM/MM e-Pathway analysis and electronic coupling calculations, allowing for a molecular and electronic comprehensive analysis of the ET process in both complexes. Our results, consistent with experimental mutational data, reveal the ET in FNR/Fd proceeding through a bridge-mediated mechanism in a dominant protein-protein complex, where transfer of the electron is facilitated by Fd loop-residues 40-49. In FNR/Fld, however, we observe a direct transfer between redox cofactors and less complex specificity than in Fd; more than one orientation in the encounter complex can be efficient in ET.

    Testosterone levels exhibit a circadian rhythm in healthy men, with morning levels tending to be higher compared to evening titers. However, circadian rhythms wane with age. Although this has been described in males living within industrialized settings, age-related changes have not received similar attention in populations outside these contexts. Because many nonindustrialized populations, such as Ache Amerindians of Paraguay, exhibit testosterone levels that are lower than what is commonly reported in the clinical literature and lack age-associated variation in testosterone, it was hypothesized that Ache men would not show age-related variation in testosterone circadian rhythms. Diurnal rhythmicity in testosterone within and between Ache men in association with age (n = 52; age range, 18-64) was therefore examined. A significant negative association was evident between the ratio of morning and evening salivary testosterone and age (r = -0.28, P = 0.04). Men in their third decade of life exhibited significant diurnal variation (P = 0.0003), whereas older and younger age classes did not. Men between the ages of 30 and 39 also exhibited a higher AM:PM testosterone ratio compared to 40-49 and 50< year old men (P = 0.002, 0.006). Overall, declines in testosterone with aging may not be universal among human males, however, within-individual analyses of diurnal variation capture age-related contrasts in daily testosterone fluctuations. Circadian rhythmicity differs with age among the Ache and may be a common aspect of reproductive senescence among men regardless of ecological context.

    In a cross-sectional, epidemiological and parasitological study of human filariasis, 845 individuals were examined in settlements along the Igwun Basin, Imo State, Nigeria. Four different filarial nematode species were identified. Two hundred and fifty-six (30.3%) of the individuals examined were positive for Onchocerca volvulus, 113 (13.4%) for Mansonella perstans, 76 (9.6%) for Wuchereria bancrofti and 77 (9.1%) for Loa loa. Microfilarial rates increased with age of individuals and showed a tendency towards higher prevalence rates in males than in females. The intensity of O. volvulus infection was high, with the highest microfilarial density of 44 mf mg-1 snip which occurred in the 40-49-year-old individuals. In W. bancrofti and L. loa infections, infections of over 1000 mf 20 ml-1 blood were recorded in 15.8% and 19.5% of individuals, respectively. Observed clinical signs were associated with inflammatory, lympho-obstructive and ocular manifestations. In M. perstans infections all clinical cases were inflammatory. In W. bancrofti, 44.4% of clinical cases were inflammatory, and lympho-obstructive manifestations consisted of 23.8% chyluria, 12.7% hydrocele and 19.1% elephantiasis. In L. loa infections all clinical cases were inflammatory with indications of Calabar swellings. In O. volvulus infections 23.5% of clinical cases were inflammatory, while 76.5% showed ocular manifestations. The absence of blindness despite high O. volvulus infection rates was remarkable. The presence of potential insect vectors and the occurrence of clinical signs are indications of active transmissions.

    Sex differences in influence tactics were examined with a sample of 269 followers (67 men, 202 women) at a large midwestern national insurance company who rated the downward influence tactics used by their direct supervisors. Downward influence tactics are behaviors used by leaders to gain compliance from followers. One department within the organization was identified as a source for participants in the study. Participation was voluntary. The age range for the sample was 21 to 65 years, with the largest percentage falling in the 40-49 year range (M = 3.8, SD = .8). Hierarchical linear modeling procedures were utilized to analyze the multiple level data (leader and follower) and to examine variables within the organization at different levels of analysis. Leader participants were asked to solicit their followers to complete an influence tactic measure, which consisted of the most reliable subscales taken from the Influence Behavior Questionnaire, Schriesheim and Hinkin Influence Measure, and the Profiles of Organizational Influence Strategies. The integrated measure resulted in a 45-item scale. It was hypothesized that, overall, followers would report that male leaders would use hard influence tactics more frequently than female leaders. On the other hand, followers would report that female leaders would use soft influence tactics more frequently than male leaders. When differentiating followers by sex, however, we expected that male followers would report more than female followers that their leaders use hard tactics more frequently. Also, we expected that female followers would report (more than male followers) that their leaders use soft tactics more frequently. Overall, followers reported that male leaders used significantly more personal appeal and consultation, so called "soft tactics," with their followers than did female leaders. Female followers reported that their leaders (both male and female) used consultation and inspirational appeal more frequently

    The objective of this article is to illustrate user characteristics of a hospital's social media structure using analytics and user surveys. A 1-year retrospective analysis was conducted along with an Internet survey of users of the hospital's Facebook, Twitter, and blog. Of the survey respondents (n = 163), 95.7% are female and 4.3% are male; most are ages 50-59 years (31.5%) and 40-49 years (27.8%); and 93.2% are Caucasian. However, the hospital system database revealed 55% female and 37% minority population, respectively. Of the survey respondents, 61.4% reported having a bachelor's degree or higher, whereas only 11.7% reported having a high school degree/equivalent or lower. However, within the hospital patient databases, 93% of patients have a high school degree/equivalent or lower and only 3% have a bachelor's degree or higher in our women's services population. Social media were used to seek personal health information 68.7% (n = 112), to learn about hospital programming 27.6% (n = 45), and to seek family health information 25.2% (n = 41). Respondents younger than 49 years of age were more likely to seek personal health information using social media compared to those 50 years of age and older (p = .02). Respondents with a bachelor's degree or higher education were statistically less likely to search for physician information compared to those less educated individuals (p = .04). We conclude that social media may play an important role in personal health information, especially for young female respondents; however, the survey provides strong evidence that further research is needed to ensure that social network sites provided by hospitals are reaching the full spectrum of health system patients.

    Background Around 30% of Brazilian population is hypertensive. Brazilian’s Family Health Strategy (FHS) is a community-based approach to provide primary health care and control chronic disease as hypertension. The aims of this pilot study were to study hypertension prevalence and awareness and to analyze the feasibility of FHS program with community healthy agents (CHA) to collect data about hypertensive subjects in Matao, Brazil. Methods A cross-sectional study was conducted in subjects equal or older than 40 years old in a neighborhood belonging to FHS program. CHA were trained to collect data and to assess blood pressure (BP) with an automated device. Hypertension diagnosis was defined if systolic blood pressure ≥ 140 mm Hg or diastolic blood pressure ≥ 90 mm Hg or subject had previous use of hypertensive drug. Chi-square test and univariate logistic regression analysis were applied with significance level of 5% and a confidence interval of 95%. Results In 625 subjects, hypertension prevalence was 68.8% and women (71.9%) were more hypertensive than men (63.2%) (P = 0.02). Prevalence of hypertension increased with age group, from 46.3% (40 - 49 years) to 82.5% (70 - 79 years) (P < 0.001). The overall prevalence of pre-hypertension was 40.1%: stage 1, 25.7% and stage 2, 17.0%. Hypertension awareness was 81.8% and 79.8% reported use of anti-hypertensive drugs. BP was not controlled in 61.8% and 67.7% of them was using anti-hypertensive drugs. CHA reported no difficulties to collect data and BP assessment with the automated device. Conclusion We observed a high hypertension prevalence rate, awareness, and subjects with uncontrolled hypertension even with use of anti-hypertensive drugs. CHA from FHS program are a feasible option to BP control in future studies involving larger populations. PMID:27298661

    An increased prevalence of colorectal neoplasia has been reported in acromegalic patients, and recommendations have been made for early colonoscopic screening and regular surveillance. This assumption, however, is frequently drawn from studies using selected control populations. To clarify colonoscopic management in these patients, we undertook a 2-center prospective screening colonoscopy study in 122 acromegalics (age range, 25-82 yr). In the absence of ideal age-matched controls, we calculated prevalence rates of occult adenocarcinomas and adenomas in the general population using cumulative data in the published literature from 8 autopsy studies (model 1, n = 3,559) and 4 screening colonoscopy studies (model 2, n= 810), applying linear regression models. Of the 115 patients with complete examinations, adenocarcinomas were discovered in 3 (2.6%), and at least 1 adenoma was found in 11, giving an overall prevalence of neoplasia of 12% (14 of 115). Prevalence rates for age bands 30-40, 40-49, 50-59, 60-69, and 70+ yr were 0%, 8%, 12%, 20%, and 21%, respectively. Compared with the 2 control models, the prevalence of occult colorectal cancer was not significantly increased (acromegalics vs. models 1 and 2, 2.6% vs. 2.3% and 0.9%), nor was there an increase in the prevalence of adenomas in any age band. Pathological characteristics showed some differences, in that adenomas in acromegalics tended to be right sided (68% vs. 57% and 56%), larger (for > or =10 mm, 27% vs. 13% and 9%), and of advanced histology (for tubulovillous, 27% vs. 4% and 22%). No associations were found between the presence of colonic neoplasia and the duration of disease, total GH exposure, cure status, and serum insulin-like growth factor I. This study has failed to demonstrate an increased prevalence of neoplasia in acromegalic patients compared with the expected prevalence in the general population and questions the need for an aggressive colonoscopic screening policy.

    Intervertebral disc degeneration (IDD) is one of the most common skeletal disorders, yet few data are available in Asian populations. We sought to assess the prevalence and pattern of radiographic IDD in a Vietnamese population. This population-based cross-sectional investigation involved 170 men and 488 women aged ≥40 years, who were randomly sampled from the Ho Chi Minh City (Vietnam). Anthropometric data, clinical history and self-reported back and neck pain were ascertained by a questionnaire. Plain radiographs (from the cervical spine, thoracic spine to the lumbar spine) were examined for the presence of disc space narrowing and/or osteophytosis using the Kellgren-Lawrence (KL) grading system. The presence of radiographic IDD was defined if the KL grade was 2 or greater in at least one disc. The prevalence of radiographic IDD was 62.4% (n = 106) in men and 54.7% (n = 267) in women. The most frequently affected site was the lumbar spine with prevalence being 50.6 and 43.2% in men and women, respectively. The prevalence of IDD increased with advancing age: 18.8% among those aged 40-49 years, and increased to 83.4% in those aged ≥60 years. Self-reported neck pain and lower back pain were found in 30 and 44% of individuals, respectively. There was no statistically significant association between self-reported neck pain and cervical spine OA. These data suggest that radiographic IDD is highly prevalent in the Vietnamese population, and that self-reported back pain is not a sensitive indicator of IDD. PMID:25791571

    AIM: To evaluate the discomfort associated with esophagogastroduodenoscopy (EGD) using an ultrathin endoscope through different insertion routes. METHODS: This study (January 2012-March 2013) included 1971 consecutive patients [male/female (M/F), 1158/813, 57.5 ± 11.9 years] who visited a single institute for annual health checkups. Transnasal EGD was performed in 1394 patients and transoral EGD in 577. EGD-associated discomfort was assessed using a visual analog scale score (VAS score: 0-10). RESULTS: Multivariate analysis revealed gender (M vs F: 4.02 ± 2.15 vs 5.06 ± 2.43) as the only independent predictor of the VAS score in 180 patients who underwent EGD for the first time; whereas it revealed gender (M vs F 3.60 ± 2.20 vs 4.84 ± 2.37), operator, age group (A: < 39 years; B: 40-49 years; C: 50-59 years; D: 60-69 years; E: > 70 years; A/B/C/D/E: 4.99 ± 2.32/4.34 ± 2.49/4.19 ± 2.31/3.99 ± 2.27/3.63 ± 2.31), and type of insertion as independent predictors in the remaining patients. Subanalysis for gender, age group, and insertion route revealed that the VAS score decreased with age regardless of gender and insertion route, was high in female patients regardless of age and insertion route, and was low in males aged over 60 years who underwent transoral insertion. CONCLUSION: Although comprehensive analysis revealed that the insertion route may not be an independent predictor of the VAS score, transoral insertion may reduce EGD-associated discomfort in elderly patients.

    This cross sectional study was carried out in the Infertility Unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2011 and June 2013. Eighty one (81) consecutive azoospermic male partner of married couple, aged 20-50 years with at least two years of subfertility and no known endocrinopathy and ejaculatory dysfunction were included in this study to find out their abnormal hormonal pattern. None of them had received any form of treatment within the last 3 months prior to hormonal evaluation. Men with hypertension, recent fever, chemo or radiation exposure were excluded from the study. Eight weeks interval two semen analyses were done in the Andrology Laboratory of above department following standard WHO guideline, 2004. Using standard ELISA technique, serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and prolactin were measured/assayed/estimated. The results of this study demonstrated that 40 (49.4%) men had normal endocrine pattern against 51 (50.6%) with endocrinopathy. The former may be related to obstructive azoospermia, which needs further analyses. Both the increased FSH (>11.1mIU/ml) and LH (>7.6mIU/ml) were observed in 25 (30.9%) men, only elevated FSH (>11.1mIU/ml) in 9(11.1%), and only elevated LH (>7.6mIU/ml) in 7(8.6%). Low testosterone level (<270ng/dl) was observed in 11(13.6%), low TSH (<0.4μIU/ml) in 1(1.2%) and low prolactin (<2.5ng/dl) in 5(6.2%).

    Immune dysregulation and altered T-cell hemostasis play important roles in the pathogenesis of myelodysplastic syndromes (MDS). Recent studies suggest an increased risk of MDS among patients with autoimmune diseases. Here, we investigated the prevalence of autoimmune diseases among MDS patients, comparing characteristics and outcomes in those with and without autoimmune diseases. From our study group of 1408 MDS patients, 391 (28%) had autoimmune disease, with hypothyroidism being the most common type, accounting for 44% (n = 171) of patients (12% among all MDS patients analyzed). Other autoimmune diseases with ≥5% prevalence included idiopathic thrombocytopenic purpura in 12% (n = 46), rheumatoid arthritis in 10% (n = 41), and psoriasis in 7% (n = 28) of patients. Autoimmune diseases were more common in female MDS patients, those with RA or RCMD WHO subtype, and those who were less dependent on red blood cell transfusion. Median overall survival (OS) was 60 months (95% CI, 50-70) for patients with autoimmune diseases versus 45 months (95% CI, 40-49) for those without (log-rank test, P = 0.006). By multivariate analysis adjusting for revised IPSS and age >60 years, autoimmune diseases were a statistically significant independent factor for OS (HR 0.78; 95% CI, 0.66-0.92; P = 0.004). The rate of acute myeloid leukemia (AML) transformation was 23% (n = 89) in MDS patients with autoimmune disease versus 30% (n = 301) in those without (P = 0.011). Patient groups did not differ in response to azacitidine or lenalidomide treatment. Autoimmune diseases are prevalent among MDS patients. MDS patients with autoimmune diseases have better OS and less AML transformation.

    AIM To investigate the prevalence of and risk factors for lens opacities in populations living at two different altitudes in China. METHODS A total of 813 subjects aged ≥40y in Lhasa (Tibet Autonomous Region, China. Altitude: 3658 m) and Shaoxing (Zhejiang Province, China. Altitude: 15 m) were underwent eye examinations and interviewed in this cross-sectional study. Participants' lens opacities were graded according to the Lens Opacities Classification System II (LOCS II) and the types of opacities with LOCS II scores ≥2 were determined. Univariate and stepwise logistic regression were used to evaluate the associations of independent risk factors with lens opacities. RESULTS Lens opacities were significantly more prevalent in the high-altitude than in the low-altitude area (χ2=10.54, P<0.001). Lens opacities appear to develop earlier in people living at high than at low altitude. The main types of lens opacity in Lhasa and Shaoxing were mixed (23.81%) and cortical (17.87%), respectively. Independent risk factors associated with all lens opacities were age, ultraviolet (UV) radiation exposure, and educational level. Compared with participants aged 40-49y, the risk of lens opacities increased gradually from 2 to 85 times per 10y [odds ratio (OR)=2.168-84.731, P<0.05). The risk of lens opacities was about two times greater in participants with the highest UV exposure than in those with the lowest exposure (OR=2.606, P=0.001). Educational level was inversely associated with lens opacities; literacy deceased the risk by about 25% compared with illiteracy (OR=0.758, P=0.041). CONCLUSION Old age, higher UV exposure and lower educational level are important risk factors for the development of lens opacities. Lens opacities are more prevalent among high-altitude than low-altitude inhabitants. PMID:27162738

    This study aimed to determine if there was an association between the implementation of smoking regulation policies and the urine cotinine concentrations of Korean non-smokers. The subjects of this study were 4612 non-smoking Korean citizens (aged 19 or older) selected from the first stage of the Korean National Environmental Health Survey conducted by the National Institute of Environmental Research from 2009 to 2011. Cotinine concentrations in urine were measured by GC-MS (limit of detection: 0.05 ng/mL). Changes in the urine cotinine concentration were analyzed using a weighted general linear model and linear regression and values were shown as geometric mean (GM). The GM urine cotinine concentration decreased over time (2.92 ng/mL in 2009, 1.93 ng/mL in 2010, and 1.25 ng/mL in 2011). The total decrease in the subjects' urine cotinine concentration between 2009 and 2011 was 2.79 ng/mL, representing a relative decrease of 54.7%. The decrease in GM urine cotinine concentration in each subgroup ranged from 2.17 ng/mL to 3.29 ng/mL (relative decreases of 46.4% and 62.8%, respectively), with the largest absolute reductions in subjects in the following groups: females, aged 40-49 years, detached residence type, no alcohol consumption, employed, secondhand smoke exposure. All groups had negative regression coefficients, all of which were significant (p < 0.001). Our results provide indirect indicators of the effectiveness of smoking regulation policies including the revision of the National Health Promotion Act in Korea. PMID:26507969

    Introduction Endometrial polyp is one of the common causes of Abnormal Uterine Bleeding (AUB) in the reproductive age group as well as postmenopausal age group. Aim To study the clinical features of endometrial polyp and the safety and feasibility of blind polypectomy following diagnostic hysteroscopy. Materials and Methods Total of 256 women who were diagnosed to have endometrial polyp by transvaginal ultrasound and underwent diagnostic hysteroscopy and blind polypectomy by simple avulsion in the period of January 2008 to December 2014 were included in our study. Polyp was confirmed by the histopathology. Results The prevalence of polyp among women who underwent diagnostic hysteroscopy and blind polypectomy was more common in the age group of 40-49years. Polyps manifested as AUB in 45.6% of our study population. The mean size of the polyp was not significantly different between premenopausal and postmenopausal women and single and multiple polyps. Histopathological study of the polyp showed two malignant polyps in our study population. Premalignant lesions i.e., endometrial hyperplasia without atypia and with atypia was found in 33 women. There was one uterine perforation, one cervical tear; one false passage and one patient had mild bleeding after the procedure. In our study, in the mean follow-up period of 37.57±28.12 months, 3.9% (7 women) had recurrence. In the follow-up period of 16.56±18.96 months, 78.9% women didn’t have recurrence. Conclusion Diagnostic hysteroscopy and blind polypectomy has low complication rate and recurrence rate and technically feasible for the practicing gynaecologists which don’t need much training and is cost-effective also.

  18. Curbing child marriages.

    PubMed

    Rajan, S I

    Demographers are interested in marriage age because women who marry early are exposed to conceptions through the most fecund years of their lives. Women who marry young are exposed comparatively to a longer duration and tend to shorten the intergenerational years, consequently influencing the fertility to be higher. In India, despite the law, child marriages occur in many states, more prevalent among the backward conservative communities. According to India's Child Marriage Restraint Act, a woman must be 18 to marry (a man 21), but in fact in 1981 the marriage age of females was 15. This young marriage age is substantiated by available survey and report data. For example, in a mass marriage solemnized at Wardha village in Vidisha district in 1981, there was not 1 of the 110 couples of the prescribed marriage age. 55 of the brides were below age 10 and 48 were between 10-12 years. Only 8 brides were older than 14 years. A survey conducted by the Population Research Center, Lucknow University, revealed that more than half of the females surveyed were married before age 15. The census data for 1981 provide the following information: 1.19 million or 2.63% of the total 45.18 million boys aged 10-14 years and 2.67 million or 6.59% of the total 40.49 million girls were married. Christians had the highest mean age at marriage followed by Sikhs and Jains, but all religious groups had shown an improvement in their age at marriage. Several factors are responsible for child marriage. Consequently, a multidimensional approach to dealing with the problem is needed. The way to bring about this change is through creating more job and educational opportunities for women.

  19. Executive women and the myth of having it all.

    Hewlett, Sylvia Ann

    2002-04-01

    When it comes to having a high-powered career and a family, the painful truth is that women in the United States don't "have it all." At midlife, in fact, at least a third of the country's high-achieving women--a category that includes high wage earners across a variety of professions--do not have children. For many, this wasn't a conscious choice: Indeed, most yearn for motherhood. So finds economist Sylvia Ann Hewlett, who recently fielded a nationwide survey to explore the professional and private lives of highly educated and high-earning women. Other findings are similarly disturbing. Many of these women who are raising children have suffered insurmountable career setbacks. In addition, today's young women will likely experience even starker trade-offs. In general, Hewlett's data show that, for too many women, the demands of ambitious careers, the asymmetries of male-female relationships, and the difficulties of conceiving later in life undermine the possibility of combining high-level work with family. By contrast, Hewlett's research reveals that high-achieving men continue to "have it all." Of the men she surveyed, 79% report wanting children, and 75% have them. Indeed, the more successful the man, the more likely he is to have a spouse and children. The opposite holds true for women, particularly the highest-achieving women in Hewlett's survey: At age 40, 49% of these ultra-achievers are childless, while 19% of their male peers are. The facts and figures are bleak but, the author contends, could be liberating if they spur action. Hewlett urges lawmakers and corporations to establish policies that support working parents. But recognizing that changes won't happen overnight, she exhorts young women to be more deliberate about their career and family choices. PMID:11930783

    OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age) residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9%) were in males, and 21 (29.2%) of the patients were in the 40-49 year age bracket. The majority (85.3%) described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions. PMID:24068270

    Stereotactic biopsy is often performed for diagnostic purposes before treating patients whose imaging studies highly suggest glioma. Indications cited for biopsy include diagnosis and/or the "inoperability" of the tumor. This study questions the routine use of stereotactic biopsy in the initial management of gliomas. At The University of Texas M. D. Anderson Cancer Center, we retrospectively reviewed a consecutive series of 81 patients whose imaging studies suggested glioma and who underwent stereotactic biopsy followed by craniotomy/resection (within 60 days) between 1993 and 1998. All relevant clinical and imaging information was reviewed, including computerized volumetric analysis of the tumors based on pre- and postoperative MRI. Stereotactic biopsy was performed at institutions other than M. D. Anderson in 78 (96%) of 81 patients. The majority of tumors were located either in eloquent brain (36 of 81 = 44%) or near-eloquent brain (41 of 81 = 51%), and this frequently was the rationale cited for performing stereotactic biopsy. Gross total resection (>95%) was achieved in 46 (57%) of 81 patients, with a median extent of resection of 96% for this series. Diagnoses based on biopsy or resection in the same patient differed in 40 (49%) of 82 cases. This discrepancy was reduced to 30 (38%) of 80 cases when the biopsy slides were reviewed preoperatively by each of three neuropathologists at M. D. Anderson. Major neurologic complications occurred in 10 (12.3%) of 81 surgical patients and 3 (3.7%) of 81 patients undergoing biopsy. Surgical morbidity was probably higher in our series than it would be for glioma patients in general because our patients represent a highly selected subset of glioma patients whose tumors present a technical challenge to remove. Stereotactic biopsy is frequently inaccurate in providing a correct diagnosis and is associated with additional risk and cost. If stereotactic biopsy is performed, expert neuropathology consultation should be sought

    Despite rapid advances in medicine and beneficial lifestyle changes, the incidence and mortality rate of gynecologic carcinoma remains high worldwide. This paper presents the econometric model findings of the major drivers of breast cancer mortality among US women. The results have implications for public health policy formulation on disease incidence and the drivers of mortality risks. The research methodology is a fixed-effects GLS regression model of breast cancer mortality in US females age 25 and above, using 1990-1997 time-series data pooled across 50 US states and DC. The covariates are age, years schooled, family income, 'screening' mammography, insurance coverage types, race, and US census region. The regressions have strong explanatory powers. Finding education and income to be significantly and positively correlated with mortality supports the 'life in the fast lanes' hypothesis of Phelps. The policy of raising a woman's education at a given income appears more beneficial than raising her income at a given education level. The relatively higher mortality rate for Blacks suggests implementing culturally appropriate set of disease prevention and health promotion programs and policies. Mortality differs across insurance types with Medicaid the worst suggesting need for program reform. Mortality is greater for women ages 25-44 years, females 40-49 years who have had screening mammography, smokers, and residents of some US states. These findings suggest imposing more effective tobacco use control policies (e.g., imposing a special tobacco tax on adult smokers), creating a more tractable screening mammography surveillance system, and designing region-specific programs to cut breast cancer mortality risks.

    Testing for high-risk (hr) types of human papillomavirus (HPV) is highly sensitive as a screening test of high-grade cervical intraepithelial neoplastic (CIN2/3) disease, the precursor of cervical cancer. However, it has a relatively low specificity. Our objective was to develop a prediction rule with a higher specificity, using combinations of human and HPV DNA methylation. Exfoliated cervical specimens from colposcopy-referral cohorts in London were analyzed for DNA methylation levels by pyrosequencing in the L1 and L2 regions of HPV16, HPV18, HPV31 and human genes EPB41L3, DPYS and MAL. Samples from 1,493 hrHPV-positive women were assessed and of these 556 were found to have CIN2/3 at biopsy; 556 tested positive for HPV16 (323 CIN2/3), 201 for HPV18 (73 CIN2/3) and 202 for HPV31 (98 CIN2/3). The prediction rule included EPB41L3 and HPV and had area under curve 0.80 (95% CI 0.78-0.82). For 90% sensitivity, specificity was 36% (33-40) and positive predictive value (PPV) was 46% (43-48). By HPV type, 90% sensitivity corresponded to the following specificities and PPV, respectively: HPV16, 38% (32-45) and 67% (63-71); HPV18, 53% (45-62) and 52% (45-59); HPV31, 39% (31-49) and 58% (51-65); HPV16, 18 or 31, 44% (40-49) and 62% (59-65) and other hrHPV 17% (14-21) and 21% (18-24). We conclude that a methylation assay in hrHPV-positive women might improve PPV with minimal sensitivity loss.

    Background No studies have estimated the population-level burden of morbidity in individuals diagnosed with cancer as children (ages 0-19 years). We updated prevalence estimates of childhood cancer survivors as of 2011 and burden of morbidity in this population reflected by chronic conditions, neurocognitive dysfunction, compromised health-related quality of life and health status (general health, mental health, functional impairment, functional limitations, pain and fear/anxiety). Methods Surveillance Epidemiology and End Results Program data from 1975 to 2011 were used to update the prevalence of survivors of childhood cancers in the US. Childhood Cancer Survivor Study data were used to obtain estimates of morbidity burden indicators which were then extrapolated to SEER data to obtain population-level estimates. Results There were an estimated 388,501 survivors of childhood cancer in the US as of January 1, 2011, of whom 83.5% are ≥5 years post-diagnosis. The prevalence of any chronic condition among ≥5-year survivors ranged from 66% (ages 5-19) to 88% (ages 40-49). Estimates for specific morbidities ranged from 12% (pain) to 35% (neurocognitive dysfunction). Generally, morbidities increased by age. However, mental health and anxiety remained fairly stable and neurocognitive dysfunction exhibited initial decline and then remained stable by time since diagnosis. Conclusions The estimated prevalence of survivors of childhood cancer is increasing, as is the estimated prevalence of morbidity in those ≥5 years post-diagnosis. Impact Efforts to understand how to effectively decrease morbidity burden and incorporate effective care coordination and rehabilitation models to optimize longevity and well-being in this population should be a priority.

    Objective: The aim of this study was to determine the prevalence of Candida carriage and Candida species among cigarette and Maras powder (MP) users. Material and methods: This study was conducted on 180 volunteering men in 20 cafehouses in the city of Kahramanmaras, Turkey. The sociodemographic characteristics of the participants and the behaviors of MP and cigarette usage were noted down. Culture specimens were obtained from bilateral buccal mucosa and dorsum of the tongue with a sterile cotton-tipped swap. Results: The specimens were inoculated into Sabouraud Dextrose Agar. The mean age of the participants was 40.49 ± 12.89 years (min = 18, max = 87). Fifty-eight percent of the cigarette users, 56.7% of the MP users, and 36.7% of the control group were Candida carriers. The difference of Candida carriage between cigarette and MP users and the control group was statistically significant (P = 0.018 and P = 0.029 respectively). The prevalence of Candida carriage was similar between cigarette and MP users (P = 0.854). The most frequently isolated species was Candida albicans at a rate of 30% in the cigarette users’ group, 28.3% in the MP users’ group and at a rate of 18.3% in the controls. The prevalence of Candida tropicalis carriage was found to be at a rate of 20% in cigarette and 21.7% in the MP users’ group compared to 11.7% in the nonusers. Conclusions: In the present study we found that the prevalence of oral Candida carriage was significantly higher among cigarette and MP users. PMID:26309667

    Vitamin D production is critical not only for rickets prevention but for its role in several chronic diseases of adulthood. Maternal vitamin D status also has consequences for the developing fetus. This study assessed the prevalence of vitamin D deficiency (serum 25-hydroxyvitamin D [25(OH)D]<20ng/ml) and insufficiency [25(OH)D=20-29ng/ml] in spring, among reproductive age Mongolian women. Blood was drawn in March and April, 2009 from 420 Mongolian women, 18-44 years of age. Serum 25(OH)D concentrations were measured, anthropometric measurements were performed and information was collected by interview on lifestyle, dietary and reproductive factors. Logarithm-transformed 25(OH)D levels were compared across risk factor categories by analysis of variance. Linear regression analysis was used to assess the independent associations of factors with vitamin D status. Cutaneous vitamin D3 synthesis was assessed between December and July using a standard 7-dehydrocholesterol ampoule model. The vast majority of women 415 (98.8%) had serum 25(OH)D<20ng/ml (50nmol/l) with an additional 4 women (<1%) in the insufficient range (20-29ng/ml); only one women (0.2%) had sufficient levels (>30ng/ml or 75nmol/l). 25(OH)D concentrations were positively and independently associated with educational status and use of vitamin D supplements, but not with other demographic, lifestyle, reproductive, or anthropometric factors. 25(OH)D levels were not associated with dietary factors in this population, as there is little access to foods containing vitamin D in Mongolia. No production of previtamin D3 was observed until March and was maximally effective in April and was sustained through July. These data suggest that the prevalence of vitamin D deficiency in spring among reproductive age women in Mongolia is high. Given the lack of naturally vitamin D-rich food in the diet and limited use of vitamin D supplements, food fortification and/or supplementation with vitamin D should be considered

    1992-06-01

    Minister Peng of the State Family Planning (FP) Commission of China's remarks are summarized. A major new achievement in 1991 was the meeting of population targets in FP. The birth rate for 1991 was 19.68/1000, which was lower than the 1991 target by .118%. The rate of natural increase was 12.98/1000, which was also lower. 1991 marks the lowest population increase in 6 years. Even though those 20-29 years and those at peak childbearing years increased over 1990, the rate of natural increase still declined by .1%. The decline is attributed to the strengthening of all Party leadership over FP; to more widespread publicity and education on FP and acceptance; more conscientious contraception, including permanent methods, and effective FP research; and strengthening of grassroots level FP. 1992 is the year of the 3rd baby boom peak since 1949. 318.9 million will be of childbearing age in 1992, which is an increase of 4.1 million; 13.25 million will be those at the peak age (23 years); 123.7 million will be fecund ages (20-29 years). Continued work is required in strengthening FP, in improving management of population and FP targets, in extensive and penetrating publicity on FP, on consistent and focused FP policy implementation, on increasing input for FP programs, and on pooling government and society's resources for administration of the population problem. Conscientious FP means responsibility and urgency in implementation, FP as a priority, and active FP effort. Earnest FP means using "down to earth" grassroots implementation which is painstaking and meticulous. Persistent FP means unremitting effort in a longterm struggle in controlling population growth. The quality of statistics needs to be improved as well as better criteria for assessment. Emphasis should be on the socioeconomic benefits of the FP program. The focus is still rural areas. The operating funds for FP have been increased to 2 yuan RMB per capita/year. Minorities should practice FP, and a conference

    Purpose: Radiation oncologists rely on available clinical information (biopsy Gleason score and prostate-specific antigen [PSA]) to determine the optimal treatment regimen for each prostate cancer patient. Existing published nomograms correlating clinical to pathologic extent of disease were based on patients treated in the 1980s and 1990s at select academic institutions. We used the Surveillance, Epidemiology, and End Results (SEER) database to examine pathologic outcomes (Gleason score and cancer stage) in early prostate cancer patients based on biopsy Gleason score and PSA concentration. Methods and Materials: This analysis included 25,858 patients whose cancer was diagnosed between 2010 and 2011, with biopsy Gleason scores of 6 to 7 and clinical stage T1 to T2 disease, who underwent radical prostatectomy. In subgroups based on biopsy Gleason score and PSA level, we report the proportion of patients with pathologically advanced disease (positive surgical margin or pT3-T4 disease) or whose Gleason score was upgraded. Logistic regression was used to examine factors associated with pathologic outcomes. Results: For patients with biopsy Gleason score 6 cancers, 84% of those with PSA <10 ng/mL had surgical T2 disease with negative margins; this decreased to 61% in patients with PSA of 20 to 29.9 ng/mL. Gleason score upgrading was seen in 43% (PSA: <10 ng/mL) to 61% (PSA: 20-29.9 ng/mL) of biopsy Gleason 6 patients. Patients with biopsy Gleason 7 cancers had a one-third (Gleason 3 + 4; PSA: <10 ng/mL) to two-thirds (Gleason 4 + 3; PSA: 20-29.9 ng/mL) probability of having pathologically advanced disease. Gleason score upgrading was seen in 11% to 19% of patients with biopsy Gleason 4 + 3 cancers. Multivariable analysis showed that higher PSA and older age were associated with Gleason score upgrading and pathologically advanced disease. Conclusions: This is the first population-based study to examine pathologic extent of disease and pathologic Gleason score

    The microstructure and mechanical properties of as-cast Co-(20-33)Cr-5Mo-N alloys were investigated to develop ductile Co-Cr-Mo alloys without Ni addition for dental applications that satisfy the requirements of the type 5 criteria in ISO 22674. The effects of the Cr and N contents on the microstructure and mechanical properties are discussed. The microstructures were evaluated using scanning electron microscopy with energy-dispersive X-ray spectroscopy (EDS), X-ray diffractometry (XRD), and electron back-scattered diffraction pattern analysis. The mechanical properties were evaluated using tensile testing. The proof strength and elongation of N-containing 33Cr satisfied the type 5 criteria in ISO 22674. ε-phase with striations was formed in the N-free (20-29)Cr alloys, while there was slight formation of ε-phase in the N-containing (20-29)Cr alloys, which disappeared in N-containing 33Cr. The lattice parameter of the γ-phase increased with increasing Cr content (i.e. N content) in the N-containing alloys, although the lattice parameter remained almost the same in the N-free alloys because of the small atomic radius difference between Co and Cr. Compositional analyses by EDS and XRD revealed that in the N-containing alloys Cr and Mo were concentrated in the cell boundary, which became enriched in N, stabilizing the γ-phase. The mechanical properties of the N-free alloys were independent of the Cr content and showed low strength and limited elongation. Strain-induced martensite was formed in all the N-free alloys after tensile testing. On the other hand, the proof strength, ultimate tensile strength, and elongation of the N-containing alloys increased with increasing Cr content (i.e. N content). Since formation of ε-phase after tensile testing was confirmed in the N-containing alloys the deformation mechanism may change from strain-induced martensite transformation to another form, such as twinning or dislocation slip, as the N content increases. Thus the N

    Objectives To investigate the risks of invasive cervical cancer after detection of atypical glandular cells (AGC) during cervical screening. Design Nationwide population based cohort study. Setting Cancer and population registries in Sweden. Participants 3 054 328 women living in Sweden at any time between 1 January 1980 and 1 July 2011 who had any record of cervical cytological testing at ages 23-59. Of these, 2 899 968 women had normal cytology results at the first screening record. The first recorded abnormal result was atypical glandular cells (AGC) in 14 625, high grade squamous intraepithelial lesion (HSIL) in 65 633, and low grade squamous intraepithelial lesions (LSIL) in 244 168. Main outcome measures Cumulative incidence of invasive cervical cancer over 15.5 years; proportion of invasive cervical cancer within six months of abnormality (prevalence); crude incidence rates for invasive cervical cancer over 0.5-15.5 years of follow-up; incidence rate ratios compared with women with normal cytology, estimated with Poisson regression adjusted for age and stratified by histopathology of cancer; distribution of clinical assessment within six months after the abnormality. Results The prevalence of cervical cancer was 1.4% for women with AGC, which was lower than for women with HSIL (2.5%) but higher than for women with LSIL (0.2%); adenocarcinoma accounted for 73.2% of the prevalent cases associated with AGC. The incidence rate of invasive cervical cancer after AGC was significantly higher than for women with normal results on cytology for up to 15.5 years and higher than HSIL and LSIL for up to 6.5 years. The incidence rate of adenocarcinoma was 61 times higher than for women with normal results on cytology in the first screening round after AGC, and remained nine times higher for up to 15.5 years. Incidence and prevalence of invasive cervical cancer was highest when AGC was found at ages 30-39. Only 54% of women with AGC underwent histology assessment

    A total of 93 infertile and 70 fertile men attending various urology and gynecology clinics in Jordan were investigated in this prospective study. First void urine and the corresponding semen specimens were collected from 96% of the patients. Presence of Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), and Mycoplasma genitalium (MG) DNA in specimen was detected using polymerase chain reaction. The distribution of NG, CT, UU, and MG in semen and FVU specimens among infertile versus fertile men was 6.5% versus 0%, 4.3% versus 1.4%, 10.8% versus 5.7%, and 3.2% versus 1.4%, respectively. Two of infertile and 1 of fertile men harbored mixed pathogens. The highest number of positive potential pathogens was found among young men aged 20-29 years old. The present study found a very high concordance between the detection of CT, UU, and MG DNA in semen and the corresponding FVU specimens, while NG DNA found only in semen and not in the corresponding FVU specimens. This study also revealed that Ureaplasma parvum species is more prevalent than Ureaplasma urealyticum in specimens of infertile men (90%). The study demonstrates that infertile men have higher prevalence of NG, CT, UU, and MG compared with fertile men and NG as significantly associated with infertile men.

    This population-based registry was designed to provide robust and updated information on the characteristics and the epidemiology of chronic myeloid leukemia (CML). All cases of newly diagnosed Philadelphia positive, BCR-ABL1+ CML that occurred in a sample of 92.5 million adults living in 20 European countries, were registered over a median period of 39 months. 94.3% of the 2904 CML patients were diagnosed in chronic phase (CP). Median age was 56 years. 55.5% of patients had comorbidities, mainly cardiovascular (41.9%). High-risk patients were 24.7% by Sokal, 10.8% by EURO, and 11.8% by EUTOS risk scores. The raw incidence increased with age from 0.39/100,000/year in people 20-29 years old to 1.52 in those >70 years old, and showed a maximum of 1.39 in Italy and a minimum of 0.69 in Poland (all countries together: 0.99). The proportion of Sokal and Euro score high-risk patients seen in many countries indicates that trial patients were not a positive selection. Thus from a clinical point of view the results of most trials can be generalized to most countries. The incidences observed among European countries did not differ substantially. The estimated number of new CML cases per year in Europe is about 6370. PMID:25783795

    Background: Single Widal agglutination test rather than blood culture, is commonly employed to diagnose typhoid fever in Nigeria. We took another look at the Widal agglutination test as a preferred option for diagnosis of typhoid fever by determining the specificity and sensitivity of Widal agglutination test in febrile adult patients. Materials and Methods: Two hundred and seventy-one blood samples from consecutive adults (>18 years) with febrile illness attending the General Practice Clinic of the University of Benin Teaching Hospital were tested using the Widal agglutination test, blood culture, and malaria parasite test on each sample to establish the diagnosis of typhoid fever. Results: Of the 271 blood samples 124 (45.76%) were positive following a Widal agglutination test, 60 (22.10%) blood samples grew Salmonella organisms on blood culture while 55 (20.29%) blood samples showed a co-infection of typhoid fever and malaria. A sensitivity of 35%, specificity of 51%, positive predictive value of 17%, and a negative predictive value of 73% were observed for Widal agglutination test as a diagnostic modality for typhoid fever infection. Conclusion: A single Widal agglutination test is not a valid diagnostic option for typhoid fever while co-infection with malaria parasite is the preponderant microbiological finding in typhoid fever infections. The severity of malaria parasitemia is associated with positive titers on Widal test. PMID:27397952

    The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC. The dissolution rates of resveratrol in SZC prepared by fine powder, ultrafine powder and ultrafine granules were 26.11%, 63.27%, 67.49%, respectively; and the dissolution rates of loureirin B were 7.160%, 20.29%, 23.05%, respectively. The dissolution rate of resveratrol and loureirin B in SZC prepared by ultrafine granules was the best. D90 size of ultrafine grinding was 13.221 μm and could improve the dissolution rates of resveratrol and loureirin B in SZC. PMID:26390653

    Introduction Infertility leads to significant stress among couple and the reaction to infertility differs among males and females. Aim To know the prevalence of psychiatric morbidity in infertile couples and compare the prevalence of various psychiatric disorders among husband and wife. Materials and Methods A cross-sectional study was conducted on 50 couples diagnosed with infertility from outdoor clinics. Both male and female partner of couple were interviewed for detailed history and clinical examination was done. General Health Questionnaire (GHQ-12) was applied to detect any psychological strain in couples and in those with illness, final diagnosis were made on the basis of DSM -IV (TR). The data thus generated was subjected to appropriate Statistical Analysis. Results Out of the 50 couples, 54% of females had psychiatric morbidity. The most common diagnosis amongst the female participants was MDD (Major Depressive Disorder) (18%), whereas the second most common diagnosis was GAD (Generalized Anxiety Disorder) (16%). Psychiatric morbidity was found in only 26% of males suffering with Adjustment Disorder being most common diagnosis (8%) and Dysthymia and MDD as the second most common diagnosis (6% each). Majority of patients having psychiatric morbidity were from age group 20-29 years. The difference between females and male counterparts was statistically significant. Conclusion Psychiatric morbidity was higher among female partners than male partners. The difference was statistically significant and the situation needs further workup. PMID:27630933

    Based on the 1997-2009 inventory data of Wanglang Nature Reserve, the habitat selection attributes of giant panda were studied from the aspects of topography, forest community structure, and main feeding bamboo by the methods of frequency distribution and Bailey. The giant panda had obvious habitat preferences. Topographically, the preferred microhabitat was on the even or convex slopes at the ridge, top, or middle part of mountain body at an elevation 2500-3000 m, with southwest aspect, 6 degrees-30 degrees, and the distance to the nearest water source > 300 m. As for the forest community structure, the giant panda preferred the microhabitat with the bamboo succeeded from secondary forest or mixed conifer and broad-leaved forest, and with the average tree height being 20-29 m and the shrub coverage being 0-24%. The preferred main feeding bamboo by the giant panda was the growing well Fargesia denudate with an average height of 2-5 m and the coverage of > 50%.

    The primary goal of this study was to investigate the impact of monochord (MC) sounds, a type of archaic sounds used in music therapy, on the neural complexity of EEG signals obtained from patients undergoing chemotherapy. The secondary goal was to compare the EEG signal complexity values for monochords with those for progressive muscle relaxation (PMR), an alternative therapy for relaxation. Forty cancer patients were randomly allocated to one of the two relaxation groups, MC and PMR, over a period of six months; continuous EEG signals were recorded during the first and last sessions. EEG signals were analyzed by applying signal mode complexity, a measure of complexity of neuronal oscillations. Across sessions, both groups showed a modulation of complexity of beta-2 band (20-29Hz) at midfrontal regions, but only MC group showed a modulation of complexity of theta band (3.5-7.5Hz) at posterior regions. Therefore, the neuronal complexity patterns showed different changes in EEG frequency band specific complexity resulting in two different types of interventions. Moreover, the different neural responses to listening to monochords and PMR were observed after regular relaxation interventions over a short time span.

    Intentional self-poisoning that is widely used all over the world is one of the most common methods of suicide. This study aim was to determine the rate of attempted intentional self-poisoning and to identify high risk persons in the west of Iran (Kermanshah). A total of 3138 people (1279 M and 1859 F) studied. The average annual rate of suicide in Kermanshah was 153 persons per 100 000 people. The most number of attempted intentional self-poisoning (55.5%) were in the 20-29 year age group. The most popular toxic substances for self-poisoning were drugs (71%) and oil and fuels (15%), respectively. The most number of intentional self-poisoning suicides are attempted by drugs. By considering the high rate of intentional self-poisoning, low age of suicide attempts and also its high mortality rate in Kermanshah, it is necessary to stop the opportunity to buy over-the-counter (OTC) drugs, especially those being most misused.

    OBJECTIVE: To investigate the epidemiology of gonorrhoea in an urban area in the United Kingdom. DESIGN: Analysis of all cases of gonorrhoea with regard to age, sex, ethnic group, and socioeconomic group with 1991 census data as a denominator. SETTING: Leeds, a comparatively large urban area (population around 700,000) in the United Kingdom. SUBJECTS: All residents of Leeds with culture proved cases of gonorrhoea during 1989-95. MAIN OUTCOME MEASURE: Relative risk of gonorrhoea. RESULTS: Sex, age, race, and socioeconomic group and area of residence were all independently predictive of risk of infection. Young black men aged 20-29 were at highest risk, with incidences of 3-4% per year. Black subjects were 10 times more likely than white subjects to acquire infection, and subjects from the most deprived socioeconomic areas were more than four times more likely than those from the most affluent areas to acquire infection. CONCLUSIONS: Different ethnic and socioeconomic groups vary in their risk of infection with gonorrhoea within an urban area. Targeted interventions and screening to reduce the incidence of sexually transmitted disease are now priorities. PMID:9185496

    The proportion of foreign-born people among the newly notified tuberculosis (TB) patients has been increasing in recent years and potentially poses a new challenge to TB control in Japan. In this report, we analysed the data from the Japan TB surveillance system between 2007 and 2014 to gain an overview of the trends and characteristics of foreign-born TB patients in Japan. We found that the proportion of foreign-born TB patients was especially high among the younger age groups - 44.1% among the 20-29 years age group in 2014. The largest groups of foreign-born patients were from China and the Philippines; however, the number of those from Nepal and Viet Nam was on the rise. Students comprised the second largest professional category group for TB after regular workers, and its proportion increased over the study period. Compared to Japan-born TB patients, foreign-born patients were more likely to be diagnosed through routine medical check-ups. Treatment successes and patients still on treatment were significantly lower among foreign-born patients than their Japan-born counterparts; and transferred-out and unknown outcomes were higher. Our results indicated that distinctive subgroups within the foreign-born population in Japan, especially students and regular workers, might have a higher risk of developing TB. Measures to ensure early diagnosis and treatment adherence should be adapted to such populations. PMID:27508086

    The mechanical failure of mature amyloid fibers produces fragments that act as seeds for the growth of new fibrils. Fragmentation may also be correlated with cytotoxicity. We have used steered atomistic molecular dynamics simulations to study the mechanical failure of fibrils formed by the amyloidogenic fragment of human amylin hIAPP20-29 subjected to force applied in a variety of directions. By introducing systematic variations to this peptide sequence in silico, we have also investigated the role of the amino-acid sequence in determining the mechanical stability of amyloid fibrils. Our calculations show that the force required to induce mechanical failure depends on the direction of the applied stress and upon the degree of structural order present in the β-sheet assemblies, which in turn depends on the peptide sequence. The results have implications for the importance of sequence-dependent mechanical properties on seeding the growth of new fibrils and the role of breakage events in cytotoxicity.

The ILO 1979 classification has been used in four groups of asbestos exposed subjects : two groups were hospitalized and two groups were at work. All the subjects have been investigated by a hospitalized and two groups were at work. All the subjects have been investigated by a standardized questionnaire on occupational history, PA and lateral chest X-rays and, for most them, by ferruginous bodies counting either in sputum or in bronchoalveolar lavage. The most frequent radiological signs were parenchymal fibrosis, pleural thickening, pleural calcification and diaphragmatic straightness. The fibrosis and the diaphragmatic straightness were related to the length of the exposure. Up to 20-29 years since the onset of exposure, the frequency of radiological signs was : diaphragmatic straightness more frequent than fibrosis which was more frequent than pleural thickening, which was more frequent than calcification. But the frequency of only two signs, pleural straightness and fibrosis, appeared significant after 10 years of exposure. The value of these four radiological signs as biological indicators of asbestos exposure is discussed.

    It is unclear why some people behave altruistically and others do not. This study seeks to determine what psychological features could help predict altruistic behavior. We addressed the issue by examining distinct dimensions of temperament and emotional intelligence and their associations with the level of proaltruistic aptitude in two distant age-groups, young (20-29 years) and senior (60-79 years) persons. The study was one of a self-reported psychometric survey. The major findings were that emotional intelligence, rather than temperament, is strongly associated with the expression of altruistic behavior in both young and senior subjects, despite a general decrease in the characteristics of emotional intelligence in advanced age. We also failed to substantiate the presence of an appreciable difference in the level of declared altruism between the senior and young subjects. High emotional intelligence, often underling social engagement and bonding, seems thus a good predictor of altruistic aptitude to be displayed by a person. The independence of this association of age-changes in emotional agility is suggestive of causal relationship. The study is relevant for an understanding of the enigmatic origins of important social behaviors like altruism.

    172,000 people live in Toamasina, where 22.5% of the total population is comprised of reproductive-aged women. 5 centers in the city provide family planning (FP) services. Results are presented from a study conducted to determine the attitudes of mothers and their husbands toward FP. For this study, FP is defined as couples¿ conscious efforts to control the number and spacing of births. 85.5-95.3% of mothers favored FP, with the level of approval increasing with their level of formal education received. Although 33.7% of the mothers had never heard of FP, 87.2% of these women stated their approval of the concept once it had been defined and explained. It was especially women aged 20-29 years who had never heard of FP. 13.4% of the mothers were actually using a FP method. Among these latter women, 37.7% used a hormonal method, 34.0% used a natural method, 22.6% used a surgical approach, and 5.7% used either an IUD or a barrier method. Side effects, the desire to procreate, method failure, and financial problems were noted as reasons for method discontinuation. 21% of women opposed to effective methods of FP believe that such methods cause disease, while 11.9% of husbands present in the household oppose FP, with the highest degree of opposition found among men aged 25-29 years and 40 years and older.

    The microwave dielectric properties of 0.95%MgTiO3-0.05%CaTiO3 (abbreviated as 95MCT hereafter) ceramics have been studied for application in dielectric cross coupling filters. ZnO and Nb2O5 were selected as liquid sintering aids to lower the sintering temperature and enhance the Qf value of 95MCT and simultaneously we varied the mole ratio of ZnO : Nb2O5 to tune the microwave dielectric properties of 95MCT. When the ZnO : Nb2O5 mole ratio was 1.5 and the co-doping content was 0.25 wt.%, the optimal sintering temperature of 95MCT ceramic could be lowered from 1400∘C to 1320∘C and the Qf value could be improved by about 7.7%. The optimal microwave dielectric properties obtained under this condition were Qf = 72730 GHz (6.8 GHz), ɛr = 20.29 and τf = -6.84ppm/∘C, which demonstrated great potential usage in ceramic industry. High values of Qf ceramic were used to design the dielectric cross coupling filter. The dielectric filter measured at 2.35 GHz exhibited a 6.7% bandwidth (insert loss > -3 dB) of center frequency.

    Anxiety produces maladaptive cardiovascular changes and accelerates biological aging. We evaluated cardiovascular reactivity in young and middle-aged individuals with varying anxiety scores to test the hypothesis that anxiety mimics cardiovascular aging by influencing cardiovascular autonomic modulation. The State-Trait Anxiety Inventory was used to classify healthy young individuals (20-29 years) into high (YHA, n=22;10 men) and low (YLA, n=21;10 men) anxiety, and to identify middle-aged individuals (50-60 years) with low anxiety (MLA, n=22;11 men). Heart rate, blood pressure (BP) and their variability (HRV and BPV, respectively) and baroreflex function were analyzed from beat-to-beat finger BP and electrocardiogram recordings collected during 5-min baseline, 6-min speech task (ST) and 3-min post ST recovery. Analyses of covariance showed significant differences (P<0.05) at baseline for HRV, BPV and barorelfex, and low-frequency power of systolic BP variability (LFSBP) was lower, whereas baroreflex and high frequency (HF) normalized units were higher in the YLA compared with YHA and MLA groups. Compared with YLA, YHA and MLA displayed attenuated vagal withdraw response (HF) to ST. BP and LFSBP responses to ST in YHA and MLA were higher compared with the YLA group. These findings suggest that anxiety could be linked to cardiovascular aging as it attenuates cardiac reactivity and exaggerates vascular responses to stress.

    The Number counts of far-ultraviolet (FUV) galaxies as a function of magnitude provide a direct statistical measure of the density and evolution of star-forming galaxies. We report on the results of measurements of the rest-frame FUV number counts computed from data of several fields including the Hubble Ultra Deep Field, the Hubble Deep Field North, and the GOODS-North and -South fields. These data were obtained from the Hubble Space Telescope Solar Blind Channel of the Advance Camera for Surveys. The number counts cover an AB magnitude range from 20-29 magnitudes, covering a total area of 15.9 arcmin'. We show that the number counts are lower than those in previous studies using smaller areas. The differences in the counts are likely the result of cosmic variance; our new data cover more area and more lines of sight than the previous studies. The slope of our number counts connects well with local FUV counts and they show good agreement with recent semi-analytical models based on dark matter "merger trees".

    Abstract. Metal artifacts have been a problem associated with computed tomography (CT) since its introduction. Recent techniques to mitigate this problem have included utilization of high-energy (keV) virtual monochromatic spectral (VMS) images, produced via dual-energy CT (DECT). A problem with these high-keV images is that contrast enhancement provided by all commercially available contrast media is severely reduced. Contrast agents based on higher atomic number elements can maintain contrast at the higher energy levels where artifacts are reduced. This study evaluated three such candidate elements: bismuth, tantalum, and tungsten, as well as two conventional contrast elements: iodine and barium. A water-based phantom with vials containing these five elements in solution, as well as different artifact-producing metal structures, was scanned with a DECT scanner capable of rapid operating voltage switching. In the VMS datasets, substantial reductions in the contrast were observed for iodine and barium, which suffered from contrast reductions of 97% and 91%, respectively, at 140 versus 40 keV. In comparison under the same conditions, the candidate agents demonstrated contrast enhancement reductions of only 20%, 29%, and 32% for tungsten, tantalum, and bismuth, respectively. At 140 versus 40 keV, metal artifact severity was reduced by 57% to 85% depending on the phantom configuration. PMID:26839905

    The objective of the dynamic helium charging experiment (DHCE) is to investigate the effects of concurrent helium production and fast-neutron irradiation on the physical and mechanical properties of vanadium-based alloys for fusion blanket applications. A major task in this reporting period was to disassemble the tritium-bearing DHCE capsules to retrieve irradiated specimens for examination and testing. Seven DHCE capsules containing vanadium-alloy specimens were irradiated in the MOTA-2B vehicle in FFTF to {approx}20-29 dpa. In this and the previous reporting periods, equipment and procedures were developed at Argonne National Laboratory-East to disassemble these capsules. Six of the seven capsules have been disassembled. (The seventh capsule was processed in April 1994, immediately following this reporting period.) Effluence of tritium into the cell exhaust was <2% of the total inventory. No contamination incidents occurred during the DHCE disassembly work. Initial testing of the retrieved specimens is under way. 3 refs., 1 fig., 1 tab.

    Material deprivation contributes to inequalities in health; areas of high deprivation have higher rates of ill-health. How deprivation is measured has a great impact on its explanatory power with respect to health. We compare previous deprivation measures used in Scotland and proposes a new deprivation measure using the 2001 and 2011 Scottish census data. We calculate the relative index of inequality (RII) for self-reported health and mortality. While across all age groups different deprivation measures provide similar results, the assessment of health inequalities among those aged 20-29 differs markedly according to the deprivation measure. In 2011 the RII for long-term health problem for men aged 20-24 was only 0.71 (95% CI 0.60-0.83) using the Carstairs score, but 1.10 (0.99-1.21) for the new score and 1.13 (1.03-1.24) for the income domain of Scottish Index of Multiple Deprivation (SIMD). The RII for mortality in that age group was 1.25 (0.89-1.58) for the Carstairs score, 1.69 (1.35-2.02) for the new measure and 1.76 (1.43-2.08) for SIMD. The results suggest that researchers and policy makers should consider the suitability of deprivation measures for different social groups. PMID:27082656

    Butea frondosa Koenig ex Roxb. (BF) is traditionally used to manage male sexual disorders including erectile dysfunction (ED). Methanol extract of BF (bark) inhibited Rho-kinase 2 (ROCK-II) enzyme activity in vitro with an IC50 of 20.29 ± 1.83 μg/mL. The relaxant effect of methanol extract of BF (MEBF) was studied on phenylephrine precontracted corpus cavernosum smooth muscle (CCSM) isolated from young rats. The effect of MEBF treatment on sexual behaviour of both young (5 month) and aged (24 month) rats was also studied in addition to the influence on smooth muscle, collagen (collagen-I and -III) level in penis, and sperm characteristics of young and aged rats. MEBF relaxed CCSM up to 21.77 ± 2.57% and increased sexual behavior of young and aged rats. This increase in sexual function could be attributed to ROCK-II inhibition and increase in ratio of smooth muscle to collagen level in rat penile tissue. Increased sperm production and decreased defective sperms in young and aged rats corroborate the usefulness of Butea frondosa in male infertility in addition to ED. PMID:24069061

    Microorganisms drive biogeochemical processes, but linking these processes to real changes in microbial communities under field conditions is not trivial. Here, we present a model-based approach to estimate independent contributions of microbial community shifts to ecosystem properties. The approach was tested empirically, using denitrification potential as our model process, in a spatial survey of arable land encompassing a range of edaphic conditions and two agricultural production systems. Soil nitrate was the most important single predictor of denitrification potential (the change in Akaike's information criterion, corrected for sample size, ΔAIC(c) = 20.29); however, the inclusion of biotic variables (particularly the evenness and size of denitrifier communities [ΔAIC(c) = 12.02], and the abundance of one denitrifier genotype [ΔAIC(c) = 18.04]) had a substantial effect on model precision, comparable to the inclusion of abiotic variables (biotic R2 = 0.28, abiotic R2 = 0.50, biotic + abiotic R2 = 0.76). This approach provides a valuable tool for explicitly linking microbial communities to ecosystem functioning. By making this link, we have demonstrated that including aspects of microbial community structure and diversity in biogeochemical models can improve predictions of nutrient cycling in ecosystems and enhance our understanding of ecosystem functionality.

    Background: The process of jewellery making involves the goldsmiths working with tiny visual tasks at closer working distances, which demands high visual ability. Aim: To establish vision standards for Goldsmiths. Materials and Methods: Visual task analysis was carried out in different Goldsmith workstations. The minimal visual demands of the jobs were determined based on Grundy's nomogram. Depending on the importance of certain visual functions to perform the job, criteria for visual competency was laid down. Visual abilities of goldsmiths were evaluated in order to determine their visual capability status, based on the previously laid criteria. Job competency status of goldsmiths was determined based on the supervisors’ grading with respect to the quality and quantity of work. Visual competency and job competency of goldsmiths were then compared in order to establish vision standards. Results: Visual task analysis was carried out in 91 workstations. The median of working distance, work area, critical size of the task, and illuminance were 23 cm (IQR: 20- 29), 514.5 Sq Cm (IQR: 183-746.5), and 536.5 lux (IQR: 170-536.5), respectively. Visual abilities of 113 goldsmiths were evaluated. 44.7% of goldsmiths were found to be visually competent. Job competency status of 30 goldsmiths was obtained, in which 18 (60%) were found to be highly job competent. Based on the visual demands, vision standard for jewellery makers was developed. Conclusion: The vision standards so obtained could be used as minimum visual requirements for the entry level Goldsmiths. PMID:23112504

    This study was undertaken to determine if pharmaceutical companies persuade and offer enticements to Gold Coast (Queensland, Australia) general practitioners (GPs), in an attempt to encourage them to recommend health websites to the health consumer. A survey instrument consisting of seven single response questions was mailed to 250 (61%) out of 410 GPs. Questions were designed to measure the percentages (%) and proportions associated with levels of persuasion and types of enticements pharmaceutical companies are offering GPs, in an attempt to encourage them to recommend health websites to the health consumer. The survey instrument allowed participants to indicate their (1) gender, (2) age and (3) years of experience (less experienced or= 10 years). One hundred and eight (43%) of the 250 GPs returned a completed survey. The return rate for male GPs was 72 (40%) and for female GPs, it was 36 (33%). Sixty-eight (63%) GPs indicated that they actively recommend health websites to their patients [male GPs--48 (71%), female GPs--20 (29%)]. This study highlights that female GPs (80%), those aged between 31 and 40 (77%) and GPs with < 10 years experience (72%) were more frequently targeted by pharmaceutical companies. This study reports that pharmaceutical companies are offering various types of enticements in an attempt to persuade Gold Coast GPs to recommend specific health websites to the health consumer. Further research should explore if similar levels of persuasion and types of enticements are being offered to GPs across Australia.

    The aim of this study was to investigate the efficiency of wastewater treatment by vertical flow constructed wetland systems under different hydraulic loading rates (HLR). The comparison of two types of plants, Cyperus alternifolius (Umbrella sedge) and Vetiveria zizanioides (Vetiver grass), was also conducted. In this study, six circular concrete tanks (diameter 0.8 m) were filled with fine sand and gravel to the depth of 1.23 m. Three tanks were planted with Umbrella sedge and the other three tanks were planted with Vetiver grass. Settled domestic wastewater from Chiang Mai University (chemical oxygen demand (COD), NH4(+)-N and suspended solids (SS) of 127.1, 27.4 and 29.5 mg/L on average, respectively) was intermittently applied for 45 min and rested for 3 h 15 min. The HLR of each tank was controlled at 20, 29 and 40 cm/d. It was found that the removal efficiency of the Umbrella sedge systems was higher than the Vetiver grass systems for every parameter, and the lowest HLR provided the maximum treatment efficiency. The removal efficiency of COD and nitrogen in terms of total Kjeldahl nitrogen (TKN) was 76 and 65% at 20 cm/d HLR for Umbrella sedge compared to only 67 and 56% for Vetiver grass. Nitrogen accumulation in plant biomass was also higher in Umbrella sedge than in Vetiver grass in every HLR. Umbrella sedge was thus proved to be a suitable constructed wetland plant in tropical climates.

    Sorbus decora and Sorbus americana are used traditionally as medicine by the Eeyou Istchee Cree First Nation of the James Bay region of Quebec, Canada. Because the ethanol extracts of the bark and the isolated terpenes of these plants have shown promising in vivo antidiabetic effects, an analytical method was developed and validated by RP-HPLC-ELSD for the identification and quantification of eight lupane- and ursane-type terpenes. The extraction method reproducibly recovered the compounds above 70 % and the chromatographic separation of betulin, 23-hydroxy-betulin, 23,28-dihydroxylupan-20(29)-ene-3β-caffeate, betulinic acid, α-amyrin, uvaol, 3β,23,28-trihydroxy-12-ursene, and 23,28-dihydroxyursan-12-ene-3β-caffeate was achieved within 27 min by linear gradient. The method produced highly reproducible quantitative data at interday and intraday levels. The limits of detection were in the ng level on-column with remarkable range and linearity. The target compounds were present at mg levels in the populations, collected from inland (Mistissini and Nemaska) and costal (Waskagnish and Chisasibi) Cree communities of northern Quebec. A triterpene, 23-hydroxybetulin, was the most abundant, while betulinic acid and uvaol were minor constituents. Overall, HPLC-ELSD analyses produced very similar profiles and contents of the eight compounds in the plants collected from four geographic locations. The developed HPLC-ELSD method can be used as a targeted analysis of triterpenes in these medicinal plants. PMID:27163231

    Cancer-screening behaviors, reproductive history, risk behaviors during pregnancy and chronic disease risk factors were examined in a representative sample of 566 Navajo women residing on the Navajo Reservation in 1991-1992. Among all women 15 y and older, 59% were overweight, 4% were current smokers, 10% currently used smokeless tobacco and 12% were anemic. Seventy-one percent of Navajo women aged 18 and older reported ever having had a Pap smear, but only 35% of women aged 50 and over reported ever having had a mammogram. Among parous women, the prevalence of having received no prenatal care for any pregnancy declined from 60% among women 60 and older to 13% among women 20-29 y of age, and the prevalence of ever having had a child born at home declined from 82 to 2%. These data suggest marked secular improvement in these pregnancy-related risk behaviors. However, data on cancer-screening behaviors indicate opportunities to improve health of Navajo women by increasing their use of mammography and Pap smear screening services. PMID:9339180

    An important method of drug discovery is examination of diverse life forms, including medicinal plants and natural products or bioactive compounds isolated from these sources. In cancer research, lead structures of compounds from natural sources can be used to design novel chemotherapies with enhanced biological properties. Betulinic acid (3β-hydroxy-lup-20(29)-en-28-oic acid or BetA) is a naturally occurring pentacyclic triterpene with a wide variety of biological activities, including potent antitumor properties. Non-malignant cells and normal tissues are not affected by BetA. Because BetA exerts its effects directly on the mitochondrion and triggers death of cancerous cells, it is an important alternative when certain chemotherapy drugs fail. Mitochondrion-targeted agents such as BetA hold great promise to circumvent drug resistance in human cancers. BetA is being developed by a large network of clinical trial groups with the support of the U.S. National Cancer Institute. This article discusses recent advances in research into anticancer activity of BetA, relevant modes of delivery, and the agent's therapeutic efficacy, mechanism of action, and future perspective as a pipeline anticancer drug. BetA is a potentially important agent in cancer therapeutics.

    The electrical conductivities of aqueous solutions of Li 2SO 4 and K 2SO 4 have been measured at 523-673 K at 20-29 MPa in dilute solutions for molalities up to 2 × 10 -2 mol kg -1. These conductivities have been fitted to the conductance equation of Turq, Blum, Bernard, and Kunz with a consensus mixing rule and mean spherical approximation activity coefficients. In the temperature interval 523-653 K, where the dielectric constant, ɛ, is greater than 14, the electrical conductance data can be fitted by a solution model which includes ion association to form MSO4-, MSO40, and HSO4-, where M is Li or K. The adjustable parameters of this model are the first and second dissociation constants of the M 2SO 4. For the 673 K and 300 kg m -3 state point where the Coulomb interactions are the strongest (dielectric constant, ɛ = 5), models with more extensive association give good fits to the data. In the case of the Li 2SO 4 model, including the multi-ion associate, Li(SO)80, gave an extremely good fit to the conductance data.

    Emerging data suggest that vitamin D status during childhood and adolescence can affect neurocognitive development. The purpose of this study was to investigate whether gestational 25(OH)D status is associated with early childhood cognitive and receptive language development. The Conditions Affecting Neurocognitive Development and Learning in Early Childhood Study (CANDLE) study enrolled 1503 mother-child dyads during the second trimester of healthy singleton pregnancies from Shelby County TN. Among 1020 participants of the total CANDLE cohort for whom 25(OH)D levels were available, mean gestational 25(OH)D level during the second trimester was 22.3 ng/mL (range 5.9-68.4), with 41.7% of values <20 ng/dL. Cognitive and language scaled scores increased in a stair-step manner as gestational 25(OH)D levels in the second trimester rose from <20 ng/dL, through 20-29.99 ng/dL, to ≥30 ng/dL. When controlling for socioeconomic status, race, use of tobacco products, gestational age of the child at birth, and age at the 2-year assessment, the gestational 25(OH)D was positively related to receptive language development (p < 0.017), but not cognitive or expressive language.

    This work analyzes the impact of firearm mortality between 1980 and 2012 in Argentina. For this purpose a descriptive epidemiological time trend study was carried out including the following variables: sex, age group, intentionality and jurisdiction. Data was obtained from the Office of Health Statistics and Information of the Argentine Ministry of Health. A total of 87,671 deaths due to firearms were discovered, of which 85.7% occurred in men. The highest mortality rate due to firearms corresponded to the year 2002, reaching 21.2 deaths per 100,000 inhabitants. The age group concentrating the largest number of deaths due to firearms was that of 20-29 years, accounting for 25.6% of all deaths. The highest adjusted rates corresponded to the years 2000-2002, with values of 10.0 to 11.6 deaths per 100,000 inhabitants. This time period coincides with the institutional-economic crisis the country experienced. The province of Buenos Aires was the place of residence of 49.1% of the deceased. In the discussion, political-economic and ideological-cultural dimensions of the relations among firearms, violence, science and society are considered.

    The aim of the present study was to characterize 16 pharmaceutical grade chondroitin sulfate (CS) samples, concerning the structure and presence of contaminants, in comparison to USP and analytical grade CS. Agarose gel electrophoresis has shown that only 5 samples were >90% CS, while 11 contained less than 15% CS. FACE (fluorophore-assisted carbohydrate electrophoresis) revealed that maltodextrin was the main contaminant in nine of them, and lactose in two. Raman spectroscopy corroborated these results. Concerning the structure of the CS present in the five CS-rich samples, the ratios 4-sulfated:6-sulfated disaccharides varied from 0.9 to 1.7, and their modal molecular weight was 20-29 kDa. Also, they were all contaminated by small amounts of keratan sulfate (<1%). In conclusion, our findings indicate that the composition of CS preparations not always corresponds to the manufacturers' descriptions, and indicate that further characterization should be required for the registry and license of pharmaceutical grade CS.

    Community empowerment can be a powerful determinant of HIV risk among sex workers (SWs). This study modeled the impact of social cohesion on client condom refusal among SWs in Vancouver. Longitudinal data were drawn from a prospective cohort of SWs (2010-2013). Lippman and colleagues' Social Cohesion Scale measured SWs' connectedness (i.e., perception of mutual aid, trust, support). Multivariable logistic regression examined the independent effect of social cohesion on client condom refusal. Of 654 SWs, 22 % reported baseline client condom refusal and 34 % over 3 years. The baseline median social cohesion score was 24 (IQR 20-29, range 4-45). In the final confounding model, for every one-point increase in the social cohesion score, average odds of condom refusal decreased by 3 % (AOR 0.97; 95 % CI 0.95-0.99). Community empowerment can have a direct protective effect on HIV risk. These findings highlight the need for a legal framework that enables collectivization and SW-led efforts in the HIV response.

    Thermal comfort sensations are often studied in isolation, with the subjects' attention specifically directed towards their evaluation, both by instructions and by the recurrent act of questioning. A closer approach to the field situation, in which room temperature is at most a background stimulus, is made possible by the method of spontaneous magnitude estimation of thermal sensation. Thirty-six male and 36 female 17-year-old subjects in standard cotton uniforms (0·7 clo) were exposed in groups of 4 in a climate chamber to patterns of changing air temperature typical of conditions in occupied classrooms. Temperatures remained within the range 20-29° C. and did not increase more rapidly than 4° C./hr. Each individual recorded his thermal sensation on a dial voting apparatus, registering changes spontaneously as a secondary task while performing mental work during three successive 50 min. periods, with 10 min. breaks between. It was thus possible to obtain a measure of the time course of thermal discomfort sensations, including the extent to which they distracted attention. Significant differences were found between the responses of males and females, males in general feeling hotter and reacting more rapidly to changes in temperature. Response distributions are given in detail. ImagesPlate 1 PMID:4503865

    The report presents the results of determinations of medication levels in biological materials collected from victims of suicide by hanging. The analysis included cases autopsied at Forensic Medicine Department in Bydgoszcz in the years 2005-2006. The authors observed that of 928 postmortem examinations, suicide by hanging accounted for 7.8% of cases; in this group, 11.1% victims were female and 88.9% were male. The most numerous group included individuals aged 20-29 years (20.7%), while the smallest group consisted of suicide victims below 20 years of age (8.3%). A total of 23.6% of individuals were under the influence of antidepressant drugs at the moment of death. The detected antidepressants included phenotiazine derivatives and such tricyclic antidepressants as amitryptyline, chloropromazine, clomipramine, levomepromazine, mianserin, promazine and thioridazine. Based on the above investigations, 11.1% of suicide victims may be said to have taken antidepressants in the past, but to be under no influence of such medications at the time of death.

    In this survey we investigated a population of small mammals in Eastern Croatia in order to determine Leptospira carriage rates and identify circulating serovars. Out of 67 trapped animals, 20 (29.9%) isolates were obtained. Identification of isolates using microscopic agglutination test, pulsed field gel electrophoresis and multi locus sequence typing revealed that 10 (50.0%) isolates belong to serogroup Pomona, serovar Mozdok, 6 (30.0%) isolates to serogroup Australis, serovar Jalna, 2 (10.0%) isolates to serogroup Sejroe, serovar Saxkoebing, and 1 (5.0%) isolate to serogroup Grippotyphosa, serovar Grippotyphosa. One isolate from serogroup Bataviae was unable to be identified to the serovar level. Amplification of a 331-bp region of the locus LA0322 using real-time polymerase chain reaction determined that 12 (60.0%) isolates belong to L. kirschneri, 6 (30.0%) isolates to L. interrogans, and 2 (10.0%) isolates to L. borgpetersenii. Leptospira carriage rate was high (29.9%), which corresponds to a high incidence of human and domestic animal leptospirosis in Eastern Croatia. Furthermore, 90.0% of the isolates belong to serogroups Pomona, Australis and Sejroe which are also the most prevalent serogroups in humans in this area. These findings suggest that small mammals might be an important source of Leptospira spp. infection in Eastern Croatia.

    1991-01-01

    This study investigates the use of dropped neck flexion as a manoeuvre to test the restrictive abilities of two different types of soft collars, an Airway soft cervical collar and a handmade cervical rough. The range of neck flexion of 40 asymptomatic subjects aged 20-29 was assessed, both with and without collar wear, using a Spinal Rangiometer. Dropped neck flexion is described as possibly being more representative of the type of movement that a patient with neck pain will undergo, and hence a more useful manoeuvre to employ when testing for the restrictive abilities of soft cervical collars. The mean dropped flexion was 64 degrees without collar wear, 58 degrees with the Airway soft collar, and 34 degrees with the cervical rough. Only the cervical rough provided both statistically (p < 0.001) and clinically (> 15°) significant restriction of dropped neck flexion. The comfort, preparation time, and ease of application of each of these collars is not addressed in this study, and may reflect on use in clinical practice. This preliminary study provides insight and pilot data for future studies in this area. ImagesFigure 2Figure 3

    The purpose of the present study was to determine whether the ability to speechread phonological contrasts is influenced by age. Forty-eight subjects were equally represented in three age groups: 8-9 years, 11-12 years and adults (20-29 years). The Hebrew version of the Speech Pattern Contrast (HeSPAC) test was administered by speechreading alone. Results showed that: age influenced performance; performance was contrast-dependent (place contrasts highly visible, manner and vowel height partially visible and voicing contrast invisible); hierarchy of contrast performance was similar for all age groups; Hebrew and English differ in the visual accessibility to speech contrasts in final voicing only; and females were found to be poorer speechreaders than males for the partially visible contrasts. The results suggest that speechreading at the phonological level follows a developmental course. The implications of these findings extend to recommendations provided to children in noisy listening conditions, speechreading training in hearing-impaired children and those with central auditory processing disorders (CAPD), and to the design of sensory aids.

    The human papillomavirus (HPV) was detected in 20 (29%) out of 69 lung carcinomas (LCs) in Chile, by PCR and Southern blot, and was more frequently detected in squamous cell carcinoma (SQC) than in adenocarcinomas (46 vs 9%, P=0.001). HPV-16, positive in 11 cases, was the most frequently detected HPV genotype determined by DNA sequencing. HPV-16 E2/E6 ratio, estimated from real-time PCR analysis, was much lower than the unity, suggesting that at least a partial HPV-16 genome was integrated in all but one HPV-16-positive SQCs. The remaining one case was suspected to have only episomal HPV-16. Although the viral load was low in most of the LCs, a case showed the HPV-16 copy number as high as 8479 per nanogram DNA, which was even a few times higher than the minimum viral load of seven cervical carcinomas (observed viral load: 3356–609 392 per nanogram DNA). The expression of the HPV-16/18 E6 protein was found in only two HPV-16-positive SQCs (13%) but not in the case with the highest viral load. Although the viral load was in general very low and HPV E6 expression is none or weak, further studies seem warranted to examine aetiological involvement of high-risk HPV in lung carcinogenesis.

    Intentional self-poisoning that is widely used all over the world is one of the most common methods of suicide. This study aim was to determine the rate of attempted intentional self-poisoning and to identify high risk persons in the west of Iran (Kermanshah). A total of 3138 people (1279 M and 1859 F) studied. The average annual rate of suicide in Kermanshah was 153 persons per 100 000 people. The most number of attempted intentional self-poisoning (55.5%) were in the 20-29 year age group. The most popular toxic substances for self-poisoning were drugs (71%) and oil and fuels (15%), respectively. The most number of intentional self-poisoning suicides are attempted by drugs. By considering the high rate of intentional self-poisoning, low age of suicide attempts and also its high mortality rate in Kermanshah, it is necessary to stop the opportunity to buy over-the-counter (OTC) drugs, especially those being most misused.

    The aim of the study was to determine the frequency of different injuries caused by penetrating chest traumas, and also the cause and type of trauma and its accompanying injuries. This is a cross-sectional descriptive study, carried out on all patients referred to the emergency room of Shahid Bahonar Hospital, Kerman, from March 2000 to September 2008, due to penetrating chest trauma. The required information including age, sex, cause of trauma, type and site of injury, and accompanying injury was obtained and used to fill out a questionnaire and then was analyzed. 828 patients were included in the study; most of them were in the age range of 20-29. Of the patients, 97.6 % were males. The most frequent cause of trauma was stabbing, and the most frequent injuries following the trauma were pneumothorax and hemothorax. Orthopedic trauma was the most frequent accompanying injury. The most commonly used diagnostic method was plain chest radiography. In 93 % of the patients, the chest tube was placed and thoracotomy was performed for 97 % of the patients. Shahid Bahonar Hospital is a referral Trauma Centre and treats large number of chest trauma patients. Most patients need only chest tube placement as a definitive treatment. PMID:26246700

    The detection and management of potential donor-derived infections is challenging, in part due to the complexity of communications between diverse labs, organ procurement organizations (OPOs), and recipient transplant centers. We sought to determine if communication delays or errors occur in the reporting and management of donor-derived infections and if these are associated with preventable adverse events in recipients. All reported potential donor-derived transmission events reviewed by the Organ Procurement and Transplantation Network Ad Hoc Disease Transmission Advisory Committee from January 2008 to June 2010 were evaluated for communication gaps between the donor center, OPO and transplant centers. The impact on recipient outcomes was then determined. Fifty-six infection events (IEs; involving 168 recipients) were evaluated. Eighteen IEs (48 recipients) were associated with communication gaps, of which 12 resulted in adverse effects in 69% of recipients (20/29), including six deaths. When IEs and test results were reported without delay, appropriate interventions were taken, subsequently minimizing or averting recipient infection (23 IEs, 72 recipients). Communication gaps in reported IEs are frequent, occur at multiple levels in the communication process, and contribute to adverse outcomes among affected transplant recipients. Conversely, effective communication minimized or averted infection in transplant recipients.

    Bone and Joint tuberculosis (BJTB) constitutes about 10% of total extra-pulmonary TB cases. Since the BJTB is a paucibacillary condition, there has been no systematic study on the bacterial characterization, especially the epidemiological feature. Here we collected the mycobacterial clinical isolates, analyzed the clinical features and the bacteriological characteristics from 113 BJTB cases reported in China. The mean age of the cases was 40.33 years while most of the patients fell into the 20-29 year age group; local pain was the most common onset symptom of BJTB cases; mean time from symptom onset to BJTB diagnosis was 13.16 months. 31 isolates were defined as drug resistant, including 15 multidrug resistant (MDR) and 2 extensively drug resistant (XDR) isolates according to the drug susceptibility test outcomes; after spoligotyping, 87.6% (99/113) isolates were categorized as Beijing family. In contrast to the isolates from pulmonary tuberculosis patients, here the MIRU-VNTR assay did not find anything significant. A prolonged time span for BJTB diagnosis highlights the requirement of paying further attention to BJTB infection in China. This study provides essential insights into the demographic and microbial characteristics of BJTB cases in China.

    In 2014,the Centers for Disease Control and Prevention reported significant increases in cases of primary and secondary syphilis in the U.S.; among beneficiaries of the Military Health System, monthly surveillance reports tracking reportable medical events of syphilis have reflected similar increases. This analysis reports on incident cases and rates of syphilis among active component service members of the U.S. Armed Forces from 1 January 2010 through 31 August 2015. During the surveillance period, 2,976 cases of syphilis were diagnosed. Crude incidence rates increased from 30.9 cases per 100,000 person-years (p-yrs) in 2010 to 47.4 cases per 100,000 p-yrs in 2015. Males accounted for 88.7% of cases. Incidence rates of syphilis were highest among service members who were black, non-Hispanic or who were aged 20-29 years. About one-quarter of syphilis cases (24.4%; 727 cases) were diagnosed as HIV infected. Primary and secondary syphilis cases comprised 42% of all syphilis cases. Increasing rates of primary and secondary syphilis in active component service members reflect similar trends reported in the U.S. civilian population.

    Using histories of household members of Ebola virus disease (EVD) survivors in Sierra Leone, we calculated risk of EVD by age and exposure level, adjusting for confounding and clustering, and estimated relative risks. Of 937 household members in 94 households, 448 (48%) had had EVD. Highly correlated with exposure, EVD risk ranged from 83% for touching a corpse to 8% for minimal contact and varied by age group: 43% for children <2 years of age; 30% for those 5-14 years of age; and >60% for adults >30 years of age. Compared with risk for persons 20-29 years of age, exposure-adjusted relative risks were lower for those 5-9 (0.70), 10-14 (0.64), and 15-19 (0.71) years of age but not for children <2 (0.92) or 2-4 (0.97) years of age. Lower risk for 5-19-year-olds, after adjustment for exposure, suggests decreased susceptibility in this group. PMID:27144428

    Grounded in the self-determination theoretical framework (SDT) formulated by Deci and Ryan, and specifically the basic needs mini-theory (BNT), this study examined the relationship between perceptions of the motivational climate manifested in hip hop environments, satisfaction of the three basic needs, and indicators of well- and ill-being among hip hop dancers. Fifty-nine hip hop dancers (mean age: 20.29 years) completed a questionnaire assessing the variables of interest in the study. Perceptions of a task-involving climate were positively associated with satisfaction of the needs for autonomy, competence, and relatedness. Perceptions of an ego-involving climate negatively predicted relatedness. Satisfaction of the need for competence was positively associated with positive affect, and negatively linked to negative affect. Competence need satisfaction significantly mediated the relationship between a perceived task-involving climate and positive and negative affective states. In sum, the findings provided partial support for the facets of SDT and BNT. The results also indicated that promoting the task-involving features of dance learning environments may be beneficial to dancers' well-being.

    This study was undertaken to determine if pharmaceutical companies persuade and offer enticements to Gold Coast (Queensland, Australia) general practitioners (GPs), in an attempt to encourage them to recommend health websites to the health consumer. A survey instrument consisting of seven single response questions was mailed to 250 (61%) out of 410 GPs. Questions were designed to measure the percentages (%) and proportions associated with levels of persuasion and types of enticements pharmaceutical companies are offering GPs, in an attempt to encourage them to recommend health websites to the health consumer. The survey instrument allowed participants to indicate their (1) gender, (2) age and (3) years of experience (less experienced or= 10 years). One hundred and eight (43%) of the 250 GPs returned a completed survey. The return rate for male GPs was 72 (40%) and for female GPs, it was 36 (33%). Sixty-eight (63%) GPs indicated that they actively recommend health websites to their patients [male GPs--48 (71%), female GPs--20 (29%)]. This study highlights that female GPs (80%), those aged between 31 and 40 (77%) and GPs with < 10 years experience (72%) were more frequently targeted by pharmaceutical companies. This study reports that pharmaceutical companies are offering various types of enticements in an attempt to persuade Gold Coast GPs to recommend specific health websites to the health consumer. Further research should explore if similar levels of persuasion and types of enticements are being offered to GPs across Australia. PMID:19674124

    The age and seasonal incidence of 2610 patients with pityriasis versicolor in Greece were studied. Determination of the pH of Na and K ions of the sweat and the microbiol flora of the skin of pityriasis versicolor patients was undertaken. Besides these the effectiveness of a 1% selenium disulfid suspension was tested. The results indicate that the age groups of 20-29 and 30-30 years are mostly affected by the disease. A high incidence of the skin manifestation was noted during the summer and fall months. A difference of the pH of the sweat between pityriasis versicolor and healthy controls was observed, but no difference was found in the Na and K ions of the sweat among these two groups. Neither did the microbial flora from the skin lesions of patients and from corresponding sites of controls show any difference. The high relapse in this experiment indicates the relative ineffectiveness of selenium disulfid preparations when used as a 1% suspension in the treatment of pityriasis versicolor.

    Genital ulcer disease (GUD) is a risk factor in the transmission of human immuno deficiency virus (HIV). The goal of this study is to estimate proportion, identify risk factors, and improve prevention and control of GUD. This is a retrospective study of 211 cases of GUD seen between 1993 and 1997 in an urban public sexually transmitted disease (STD) clinic. Genital ulcers form 7.6% of all STDs seen. Overall, genital herpes was commonest (89 or 42.25%). It was the predominant infection (84 or 44.7%) in the males, while lymphogranuloma venereum (52 or 24.7%) was in females. The peak incidence in both sexes occurred in the 20-29 age group. Males out numbered females by a ratio of 8:1. Most of the patients were single 114 (68.3%) and most 70 or 33.3% were students. Risk markers identified were: casual sex (103 or 53.5%) and multiple sexual partners (77 or 36.5%). Both were significantly higher (P < 0.05) in single patients. Self-treatment, use of multiple drugs and incomplete course of antibiotics were also common. The need to intensify STDS education programmes to all occupational groups and to students in particular is highlighted. Commercial sex workers require periodic education, screening and treatment.

    The aim of this study was to examine trends of the number of suicides in four municipalities of West-Herzegovina Canton (Siroki Brijeg, Ljubuski, Grude, Posusje) during the period 1984 through 2008, as well as case distribution by gender, age and how the suicides were committed. Study results showed the total number of cases during the studied period was 134. Number of suicide cases in the prewar period during 8 years (1984-1991) was 33. During the war period (1992-1995) the number of cases dropped to 15. Statistically significant growth of number of suicides (86 cases) in 12 postwar years (1996-2008), compared to prewar and war figures, is interesting. Gender distribution research results showed presence of statistically significant difference in number of cases with males and females, with 106 and 28, respectively (p < 0.01). Age distribution research showed that suicide cases are more frequent with two age groups (20-29 and over 60 years), with statistically significant difference compared to figures for the other groups. Breakdown of manner how suicide was committed is the following: hanging (32%), fire weapon (22.8%), drowning in water storage cisterns (11.2%) and other manners (14.60%). Significant growth of suicide number in postwar period indicates the need for further research of socio-economic determinants of health and war traumas with the objective of putting some light on etiological factors of this cause of death.

    There is evidence that the faulty cognitions underlying an individual's playing behavior maintains and supports their gambling behavior. Sixty undergraduate students completed the South Oaks Gambling Screen (SOGS), a measure to assess pathological gambling, and a questionnaire ascertaining the type and frequency of their gambling activities. Sixteen Loto 6/49 tickets were presented to participants and ranked according to their perceived likelihood of being the winning ticket. The numbers on the tickets were categorized as: long sequences (e.g., 1-2-3-4-5-6), patterns and series in a pseudo-psychological order (e.g., 16-21-26-31-36-41), unbalanced (e.g., six numbers from 1-24 or 25-49), and those appearing to be random (e.g., 11-14-20-29-37-43). Verbal protocols of ticket selections were ranked into eight heuristics. Results revealed that for the entire sample the greatest percentage of tickets chosen for the first four selections were "random" tickets. Further, the most commonly cited reason for selecting and changing a lottery ticket was perceived randomness. The results are discussed with reference to the cognitions used when purchasing lottery tickets.

    In 2006, Massachusetts passed legislation that broadened access to health insurance for its residents. The percentage of the state population that had health insurance (obtained through either private insurance or publicly funded programs) subsequently increased, reaching 97% in 2011, leaving only 3% uninsured, compared with approximately 9%-20% uninsured among nonelderly residents in 2006. Given such high rates of insurance coverage, questions arise about the need for categorical public health programs designed to serve clients without health insurance. This report describes trends in the percentage of uninsured clients seen at community-based organizations in Massachusetts that received federal funding for one such program, the Title X family planning program. Title X program data from 2005-2012 indicate that client volume remained high throughout the period, and that the percentage of clients who were uninsured declined, from 59% in 2005 to 36% in 2012. Across years, young adults aged 20-29 years and persons whose incomes were 101%-250% of the federal poverty level were more likely to be uninsured than were persons in other age and income groups. After health-care reform, publicly funded family planning services in Massachusetts saw continued demand from uninsured and insured clients. Family planning services in other states implementing health-care reform might have a similar experience, and public health agencies are encouraged to track such trends to monitor the demand for such services and inform budget planning and resource allocation.

    Three new ursane- and four new oleanane- type triterpenoids 1-7 were isolated, along with six known compounds 8-13, from the methanolic extract of Microtropis fokienensis. All structures were elucidated by mass and NMR spectroscopic methods. The isolates 4-10 and known compounds 14-17 that were previously isolated from this material were evaluated for anti-inflammatory activity based on effects against superoxide anion generation and elastase release by neutrophils in response to fMLP/CB. 11α,30-Dihydroxy-2,3-seco-olean-12-en-2,3-dioic anhydride (7) was the first triterpene anhydride from the genus of Microtropis to have the ring A expanded to a seven-membered ring; it showed significant anti-inflammatory activity against superoxide anion generation and elastase release. Unexpectedly, 30-hydroxy-2,3-seco-lup-20(29)-ene-2,3-dioic acid (17) showed the best effect against superoxide anion generation and elastase release with IC50 values of 0.06±0.01 and 1.03±0.35 µg/mL, respectively. Compound 17 had a dioic acid function, and compound 7 had an anhydride function modification in ring A; both showed promising activity in the target assays.

    In this study, we developed a method to quantify esculetin (6,7-dihydroxycoumarin) in plasma and tissues using HPLC coupled with ultraviolet detection and measured the level of esculetin in rat plasma after oral administration. The calibration curve for esculetin was linear in the range of 4.8 ng/mL to 476.2 ng/mL, with a correlation coefficient (r(2)) of 0.996, a limit of detection value of 33.2 ng/mL, and a limit of quantification value of 100.6 ng/mL. Recovery rates for the 95.2 ng/mL and 190.5 ng/mL samples were 95.2% and 100.3%, within-runs and 104.8% and 101.0% between-runs, respectively. The relative standard deviation was less than 7% for both runs. In the pharmacokinetic analysis, the peak plasma esculetin level was reached 5 min after administration (Cmax=173.3 ng/mL; T1/2=45 min; AUC0 ~180 min=5,167.5 ng · min/mL). At 180 min post-administration (i.e., after euthanasia), esculetin was only detectable in the liver (30.87±11.33 ng/g) and the kidney (20.29±7.02 ng/g). PMID:25580397

    The present study explored the method of testing muscle mechanical properties through the linear force-velocity (F-V) relationships obtained from loaded vertical jumps. Specifically, we hypothesised that the F-V relationship parameters depicting the force, power, and velocity of the tested muscles will differ among individuals of different physical fitness. Strength trained, physically active, and sedentary male participants (N = 10 + 10 + 10; age 20-29 years) were tested on maximum countermovement and squat jumps where manipulation of external loads provided a range of F and V data. The observed F-V relationships of the tested leg muscles were approximately linear and mainly strong (median correlation coefficients ranged from 0.77 to 0.92; all p < 0.05), independently of either the tested group or the jump type. The maximum power revealed higher values in the strength trained than in the physically active and sedentary participants. This difference originated from the differences in F-intercepts, rather than from the V-intercepts. We conclude that the observed parameters could be sensitive enough to detect the differences among both the individuals of different physical fitness and various jump types. The present findings support using loaded vertical jumps and, possibly, other maximum performance multi-joint movements for the assessment of mechanical properties of active muscles. PMID:27111493

    ABSTRACT Erectile dysfunction (ED) is a common complication of pelvic fractures. To identify the vascular and neurogenic factors associated with ED, 120 patients admitted with ED after traumatic pelvic fracture between January 2009 and June 2013 were enrolled in this study. All patients answered the International Index of Erectile Function (IIEF-5) questionnaire. Nocturnal penile tumescence (NPT) testing confirmed the occurrence of ED in 96 (80%) patients on whom penile duplex ultrasound and neurophysiological testing were further performed. Of these ED patients 29 (30%) were demonstrated only with vascular abnormality, 41 (42.7%) were detected only with neural abnormality, 26 (27.1%) revealed mixed abnormalities. Of the 55 patients (29+26) with vascular problems, 7 patients (12.7%) with abnormal arterial response to intracavernous injection of Bimix (15mg papaverine and 1mg phentolamine), 31 (56.4%) with corporal veno-occlusive dysfunction and 17 (30.9%) had both problems. Of the 67 (41+26) patients with abnormal neurophysiological outcomes, 51 (76.1%) with abnormal bulbocavernosus reflex (BCR), 20 (29.9%) with pathological pudendal nerve evoked potentials (PDEPs) and 25 (37.3%) with abnormal posterior tibial somatosensory nerve evoked potentials (PTSSEPs). Our observation indicated that neurogenic factors are important for the generation of ED in patients with pelvic fracture; venous impotence is more common than arteriogenic ED. PMID:26689522

    Evaluating the function of the vestibular part of the inner ear comprises more than the classic analysis of the lateral semicircular canal function. In healthy subjects, positional alcohol nystagmus may be seen after acute alcohol ingestion. Posturography has shown a deteriorated equilibrium after even moderate doses of alcohol, which speculatively could be an effect of otolith disturbance or a central integrative effect. We tested the possibility of an otolith effect by using linear acceleration in the lateral direction by means of eccentric rotation, stimulating mainly the outermost ear's otolith organ. The subject is seated eccentrically in a rotatory chair facing the direction of rotation. Thus, the otolith organs are stimulated in steady-state rotation. The subject experiences a lateral tilt and, in darkness, is instructed to put a short light bar in the position thought to be that of a water surface, which is identical to the perceived tilt. Twenty healthy subjects (10 men, 10 women) aged 20-29 years were tested before and approximately 1 hour after ingestion of alcohol, the amounts consumed corresponding to an approximate blood alcohol level of 0.05%, well above the maximum permissible level for driving in Sweden. No significant effects of alcohol were found. The otolith function probably is not affected by moderate alcohol intoxication levels. From this point of view, equilibrium deterioration due to alcohol ingestion in the erect position is caused by a central integrative deficit and not by an otolith effect.

    The aim of this study was to investigate the efficiency of wastewater treatment by vertical flow constructed wetland systems under different hydraulic loading rates (HLR). The comparison of two types of plants, Cyperus alternifolius (Umbrella sedge) and Vetiveria zizanioides (Vetiver grass), was also conducted. In this study, six circular concrete tanks (diameter 0.8 m) were filled with fine sand and gravel to the depth of 1.23 m. Three tanks were planted with Umbrella sedge and the other three tanks were planted with Vetiver grass. Settled domestic wastewater from Chiang Mai University (chemical oxygen demand (COD), NH4(+)-N and suspended solids (SS) of 127.1, 27.4 and 29.5 mg/L on average, respectively) was intermittently applied for 45 min and rested for 3 h 15 min. The HLR of each tank was controlled at 20, 29 and 40 cm/d. It was found that the removal efficiency of the Umbrella sedge systems was higher than the Vetiver grass systems for every parameter, and the lowest HLR provided the maximum treatment efficiency. The removal efficiency of COD and nitrogen in terms of total Kjeldahl nitrogen (TKN) was 76 and 65% at 20 cm/d HLR for Umbrella sedge compared to only 67 and 56% for Vetiver grass. Nitrogen accumulation in plant biomass was also higher in Umbrella sedge than in Vetiver grass in every HLR. Umbrella sedge was thus proved to be a suitable constructed wetland plant in tropical climates. PMID:24056433

    Data from the 1980 National Natality and National Fetal Mortality Surveys were used to characterize the occupations of women during the year before delivery; to search for disproportionate numbers of adverse pregnancy outcomes in specific occupational groups; and to compare demographic, reproductive, and lifestyle characteristics of employed mothers to those of mothers not employed in the year before delivery. National estimates were derived from the sample through a complex poststratified ratio adjustment procedure. For all pregnancy outcome groups, the greatest proportion of mothers were employed in three industry categories: professional and related services, wholesale and retail trade, and manufacturing; and in four occupation categories: clerical and kindred workers; professional, technical, and kindred workers; service workers; and operatives. Compared with employed mothers of live-born infants, a greater proportion of employed mothers of low birth weight infants worked full-time but stopped working before the third trimester. Compared with unemployed mothers, a larger proportion of employed mothers were between 20-29 years old, college educated, had a total family income of $21,000 or more per year, received early prenatal care, had no previous pregnancy, and drank alcohol during pregnancy. Estimates from this study may be used to (a) provide a better perspective of the magnitude of reproductive health problems, (b) target certain industrial populations for further research, and (c) assist in identifying causes of reproductive failure.

    The aim of this study was to describe the frequency of fatalities, timing of collisions and characteristics of persons killed in train-pedestrian collisions on Finnish railways during 2005-2009. In addition, the Finnish results were compared with those collected in Sweden. The Finnish data were combined from five different sources. The results showed that 311 pedestrians were killed in train-pedestrian collisions, including 264 suicides, 35 accidents and 12 unclassified events. For each event type, most of the victims were male. Most suicide victims were in the 20-29 year age group and on average younger than people who chose some other form of suicide. About half of all victims were intoxicated by alcohol, medicines and/or drugs. Both suicides and accidents occurred most often at the end of the week but no specific peak for time of year was found. Suicides occurred most frequently from afternoon to night and accidents during the rush hours. Most train-pedestrian fatalities happened in densely populated areas. In conclusion, the effective prevention of railway suicides and accidents calls for a systems approach involving effective measures introduced by authorities responsible for urban planning, railways, education and public health.

    We have conducted again a summer institute for high-school teachers in South Carolina at Winthrop University. The target audience were 9th grade physical science teachers in schools within a 50-mile radius from Winthrop. We developed a graduate level physics professional development course covering selected topics from the physics and chemistry content areas of the South Carolina Science Standards. Delivery of the material included the traditional lectures and the following innovative approaches in science teaching: hands-on experiments, group activities, computer based data collection, group discussions, and presentations. Two master teachers assisted us during the delivery of the course which took place in June 20-29, 2007 using Winthrop facilities. Requested funds were used for the following: salary for us and master teachers, contract course fee, some of the participants' room and board, startup equipment for all the teachers, and indirect costs to Winthrop University. Startup equipment included Pasco's stand-alone and portable Xplorer GLX interface and sensors (temperature, voltage, pH, pressure, motion, and sound). What we learned and ideas for continued K-12 teacher preparation initiatives will be presented.

    Lightning generated radio atmospheric that propagates over long distances via multiple reflections through the boundaries of the Earth-ionosphere waveguide (EIWG), shows sharp dispersion near the cut-off frequency ˜1.8 kHz of the EIWG. These dispersed atmospherics at lower frequency end are called as `tweek' radio atmospherics. In order to estimate D-region electron densities at the ionospheric reflection heights we have utilized the dispersive property of tweeks observed at low latitude Indian stations Nainital (Geomag. Lat., 20.29° N) and Allahabad (Geomag. Lat., 16.05° N). Direction finding technique has also been applied to determine the source locations of causative lightning discharge of tweeks. In this perspective, the geographic locations is determined by the intersection of two circles that are drawn by taking the travelled / propagation distance by tweek atmospherics from source location to Allahabad (ALD) and Nainital (NTL) stations. These results are in good agreement with World Wide Lightning Location Network (WWLLN) data. The average D-region electron density along the propagation path varied in the range ˜20-35 el/cc at ionospheric reflection heights of 70-90 km. The tweek method has unique advantage of monitoring lower boundary of the D-region over an area of several thousand of km surrounding to the receiving stations.

    Salicornia bigelovii Torr. has been consumed not only as a popular kind of vegetable, but also as a medicinal plant to treat hypertension, cephalalgia, scurvy and cancer. The present study was designed to investigate its chemical components and cytotoxic activity. A new noroleanane-type triterpene saponin, bigelovii C (1), was separated and purified from Salicornia bigelovii Torr., along with four known triterpene saponins 2-5. The structure of bigelovii C was elucidated as 3-O-(6-O-butyl ester)-β-D-glucuropyranosyl-23-aldehyde-30-norolean-12, 20 (29)-dien-28-oic acid-28-O-β-D-glucopyranoside, according to various spectroscopic analysis and chemical characteristics. Besides Compounds 3 and 5, bigelovii C had potent cytotoxicity against three human cancer cell lines, MCF7 (breast cancer), Lovo (colon cancer) and LN229 (glioblastoma), especially MCF7. Bigelovii C inhibited the growth of MCF7 cells in dose- and time-dependent manners. Flow cytometry analysis revealed that the percentage of apoptotic cells significantly increased upon bigelovii C treatment. Rh123 staining assay indicated that bigelovii C reduced the mitochondrial membrane potential. The mechanism of cell death by bigelovii C may be attributed to the downregulation of Bcl-2 and upregulation of Bax, cleaved caspase-9, caspase-7 and PARP. These results suggested that bigelovii C may impart health benefits when consumed and should be regarded as a potential chemopreventative agent for cancer. PMID:25867827

    The purpose of this document is to present and document GFO performance analyses and results. This is the fifth Assessment Report since the initial report. This report extends the performance assessment since acceptance to 26 December 2005. The initial GFO Altimeter Engineering Assessment Report, March 2001 (NASA/TM-2001-209984/Ver.1/Vol.1) covered the GFO performance from Launch to Acceptance (10 February 1998 to 29 November 2000). The second of the series covered the performance from Acceptance to the end of Cycle 20 (29 November 2000 to 21 November 2001). The third of the series covered the performance from Acceptance to the end of Cycle 42 (29 November 2000 to 30 November 2002). The fourth of the series covered the performance from Acceptance to the end of Cycle 64 (29 November 2000 to 17 December 2003). The fifth of the series covered performance from Acceptance to the end of Cycle 86 (29 November 2000 to 17 December 2004). Since launch, we have performed a variety of GFO performance studies; an accumulative index of those studies is provided in Appendix A.

    There are 22 species of Hamacantha registered from all over the world, and frequently from deep-waters, only two of which had previously been reported from the SW Atlantic. Here we describe a third species for this area, Hamacantha (H.) boomerang sp. nov., collected from deep-sea coral mounds at Campos Basin (off Rio de Janeiro state). We found oxeas 271-630 µm long, diancistras in three size classes, 125-155, 45-69 and 20-29 µm, and toxas, 58-82 µm. This is the only Hamacantha combining oxeas and toxas, but the latter are very rare. The species approaches the Caribbean H. (H.) schmidtii (Carter, 1882), where we observed oxeas 390-495 µm long, and diancistras in three size classes, 109-124,  44-54 and 26-41 μm, however toxas appear to be absent. Both species are clearly distinct by micrometric values, as well as the overall morphology of the smaller diancistras, distinct from the intermediate category in the new species, but quite similar in H. (H.) schmidtii. Hamacantha (Vomerula) falcula approaches the new species very closely in microsclere dimensions and morphology, but is set apart by its styloid and smaller megascleres.

    In a study of 404 women (simple random sample), 20-29 years of age, 201 (group A) applying for abortion and 203 (group B) continuing their pregnancies, the women were given a questionnaire and in addition were interviewed. The aim of the study was to evaluate the spontaneous personal motives of women for abortion at a time when age is not supposed to be a common reason. The results showed that more than half of the women expressed that a bad relationship with the partner in one way or another was a motive for the abortion. Other important motives included characteristics of the women and their partners, mainly immaturity, work/studies and unsuitable life situation for having a child. Less common motives seemed to be economy, dwelling and medical and health factors. It is obvious that women in this study wanted to have a stable relationship to the child's father before they dared or wanted to have a child. Social networks in modern society seem to be too weak. The women do not want to face social and emotional problems as lonely mothers. Political decisions in the society, for example with parental benefit according to your income discourage women from continuing their pregnancies during their studies. It also seems important for the woman to feel mature enough to have a child. The provision and encouragement of methods for safer sex may be a possible way by which to reduce the number of abortions.

    The interactions of lightweight flexible airframe structures, steady and unsteady aerodynamics, and wide-bandwidth active controls on modern airplanes lead to considerable multidisciplinary design challenges. More than 25 years of mathematical and numerical methods' development, numerous basic research studies, simulations and wind-tunnel tests of simple models, wind-tunnel tests of complex models of real airplanes, as well as flight tests of actively controlled airplanes, have all contributed to the accumulation of a substantial body of knowledge in the area of aeroservoelasticity. A number of analysis codes, with the capabilities to model real airplane systems under the assumptions of linearity, have been developed. Many tests have been conducted, and results were correlated with analytical predictions. A selective sample of references covering aeroservoelastic testing programs from the 1960s to the early 1980s, as well as more recent wind-tunnel test programs of real or realistic configurations, are included in the References section of this paper. An examination of references 20-29 will reveal that in the course of development (or later modification), of almost every modern airplane with a high authority active control system, there arose a need to face aeroservoelastic problems and aeroservoelastic design challenges.

    OBJECTIVE--To describe the frequency and characteristics of asthma attacks in the United Kingdom and to compare actual management with recommended guidelines for the management of attacks. DESIGN--Correspondence survey. SETTING--218 general practices in the United Kingdom. SUBJECTS--1775 patients of all ages who had a total of 1805 asthma attacks over three months. MAIN OUTCOME MEASURES--Patient characteristics, place of management of attacks, comparison of actual management with recommended guidelines. RESULTS--Of the 1805 attacks, 300 occurred in boys aged 0-9, 144 in girls aged 0-9, and 118 in women aged 20-29. The estimated frequency of attacks in the community was 14.3 per 1000 patients per year. 1546 (86%) patients with attacks were managed within general practice, 225 (12%) were admitted to hospital, and 34 (2%) were discharged from an accident and emergency department. Two patients died. On initial presentation, 248 (14%) patients were "not breathless," 900 (50%) were "moderately breathless," 535 (30%) were "breathless and distressed," 68 (4%) were "too breathless to talk," and 2 were "moribund." Recording of clinical data was variable. Underuse of nebulised bronchodilators and systemic steroid was apparent in all grades of clinical severity. Contrary to current guidelines for asthma management, "step up" in maintenance therapy after an attack was often not practised. CONCLUSION--Reported management was at variance with recommended guidelines. This has major implications for the design and distribution of future guidelines. PMID:8461773

    Metal artifacts have been a problem associated with computed tomography (CT) since its introduction. Recent techniques to mitigate this problem have included utilization of high-energy (keV) virtual monochromatic spectral (VMS) images, produced via dual-energy CT (DECT). A problem with these high-keV images is that contrast enhancement provided by all commercially available contrast media is severely reduced. Contrast agents based on higher atomic number elements can maintain contrast at the higher energy levels where artifacts are reduced. This study evaluated three such candidate elements: bismuth, tantalum, and tungsten, as well as two conventional contrast elements: iodine and barium. A water-based phantom with vials containing these five elements in solution, as well as different artifact-producing metal structures, was scanned with a DECT scanner capable of rapid operating voltage switching. In the VMS datasets, substantial reductions in the contrast were observed for iodine and barium, which suffered from contrast reductions of 97% and 91%, respectively, at 140 versus 40 keV. In comparison under the same conditions, the candidate agents demonstrated contrast enhancement reductions of only 20%, 29%, and 32% for tungsten, tantalum, and bismuth, respectively. At 140 versus 40 keV, metal artifact severity was reduced by 57% to 85% depending on the phantom configuration. PMID:26839905

    In our earlier communication we have shown that Lupeol inhibits early responses of tumour induction in murine skin. The free radical mediated damage to the cellular macromolecules such as DNA, proteins, lipids and alteration in the activities of quinone reductase and xanthine oxidase are important biochemical parameters of tumor development. The suppression of free radical mediated damage to cellular macromolecules and induction of quinone reductase along with depletion of xanthine oxidase are prominent characteristics of chemopreventive agents. In the present investigation, we have elucidated the mechanism of action of lupeol (Lup-20 (29)-en-3beta-ol), a triterpene found in moderate amount in many vegetables, fruits and anti-tumor herbs. In the present investigation, lupeol significantly reduced the free radical mediated DNA-sugar damage and microsomal lipid peroxidation in an iron/ascorbate free radical generating system in vitro. Benzoyl peroxide, a known free radical generating tumor promoter mediated oxidation of proteins and modulation in the activities of quinone reductase as well as xanthine oxidase was significantly prevented by lupeol when tested on murine skin in vivo. It was concluded from this study that lupeol acts as an effective chemopreventive agent against cutaneous toxicity.

    A field fish survey of Dalian Lake, Shanghai was undertaken in Apr. 11-19, Apr. 27-May 8 and May 20-29, in total 24,061 fish individuals were collected, representing 22 species from 17 genera and 11 families. The dominant specie is Carassius auratus, accounting for 76.38% of the total. The eigenvalues of species diversity were showing below : Shannon-Wiener's index (H') being 1.0027, Simpson's index (lambda) being 0.5959, Pielous's index (J') being 0.3244, Margalef's index (D) being 2.0816 and relative rare species (R) being 90.91%. The fish community could be classified into 3 ecological types, which including river-sea migratory fish (3 species), river-lake migratory fish (1 species) and sedentary fish (18 species). Also they can be subcategoried into five types according to feeding habits, i.e., piscivorous fish (9 species), invertebrativorous fish (2 species), omnivores fish (7 species), planktotrophic fish (3 species), herbivorous fish (1 species). The results suggested that the biodiversity index and fish community stability are both at a low level. Compare to the lower reaches of Huangpu River, the proportion of piscivorous fish in Dalian Lake is higher, which suggested the water quality of Dalian Lake, located in the upper reaches of Huangpu River, is better than that in the downstream. It's required to intensify supervision and strengthen the environment protection of Dalian Lake to guarantee the sustainable development.

    This cross-sectional study was performed to investigate the reference values for bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) and the prevalence of osteoporosis in the Korean population by applying domestic reference data. In total, 25,043 Korean adults ≥20 yr of age (11,792 men and 13,251 women) participated in the study. The BMDs of the total hip, femoral neck, and lumbar spine were measured by DXA (Discovery-W, Hologic Inc.), and subjects with a BMD - 2.5 standard deviations or lower than the mean BMD for young adults (20-29 yr old) were considered to have osteoporosis. When applying the new reference values determined in this study from Korean subjects, the overall prevalence of osteoporosis increased in men aged ≥50 yr compared with that provided by the DXA manufacturer from Japanese subjects (12.2% vs. 7.8%, P<0.001) and decreased in postmenopausal women aged ≥50 yr (32.9% vs. 38.7%, P<0.001). According to the findings of this study, use of the reference values provided by the DXA manufacturer has resulted in the underdiagnosis of osteoporosis in Korean men and the overdiagnosis of osteoporosis in Korean women. Our data will serve as valuable reference standards for the diagnosis and management for osteoporosis in the Korean population.

    Introduction Infertility leads to significant stress among couple and the reaction to infertility differs among males and females. Aim To know the prevalence of psychiatric morbidity in infertile couples and compare the prevalence of various psychiatric disorders among husband and wife. Materials and Methods A cross-sectional study was conducted on 50 couples diagnosed with infertility from outdoor clinics. Both male and female partner of couple were interviewed for detailed history and clinical examination was done. General Health Questionnaire (GHQ-12) was applied to detect any psychological strain in couples and in those with illness, final diagnosis were made on the basis of DSM -IV (TR). The data thus generated was subjected to appropriate Statistical Analysis. Results Out of the 50 couples, 54% of females had psychiatric morbidity. The most common diagnosis amongst the female participants was MDD (Major Depressive Disorder) (18%), whereas the second most common diagnosis was GAD (Generalized Anxiety Disorder) (16%). Psychiatric morbidity was found in only 26% of males suffering with Adjustment Disorder being most common diagnosis (8%) and Dysthymia and MDD as the second most common diagnosis (6% each). Majority of patients having psychiatric morbidity were from age group 20-29 years. The difference between females and male counterparts was statistically significant. Conclusion Psychiatric morbidity was higher among female partners than male partners. The difference was statistically significant and the situation needs further workup.

    Between October 1972 and April 1978, 34 patients with locally advanced sarcomas were treated with fast neutrons using the Texas A and M variable energy cyclotron. The clinical material included 29 patients with soft tissue sarcomas, 4 with chondrosarcomas, and one with an osteosarcoma. The best results were achieved for patients with soft tissue sarcomas; 69% (20/29) had local control of their tumor. Only one of 4 patients with chondrosarcomas was classified as having local tumor control, and one patient with osteosarcoma had persistent disease. With most fractionation schedules, local tumor control was superior for patients who received doses greater than 6500 rad/sub eq/ (2100 rad/sub n..gamma../ with 50 MeV/sub d ..-->.. Be/ neutrons). The incidence of major complications was notably increased when maximum radiation doses of 7500 rad/sub eq/ or greater were administered (2400 rad/sub n..gamma../ with 50 MeV/sub d ..-->.. Be/ neutrons). In patients who underwent subsequent surgery, healing was satisfactory if the maximum radiation dose was limited to 4500 to 5500 rad/sub eq/(1450 to 1775 rad/sub n..gamma../ with 50 MeV/sub d ..-->.. Be/ neutrons).

    Several samples from a Tertiary carbonated evaporitic series (Sainte-Cecile, Camargue, France) were investigated. Their analysis revealed a high abundance of new or uncommon hydrocarbons and organic S compounds related to higher plant triterpenes. Several of them, in particular, 12,29-cyclolupa-12,18,20(29)-triene 1, could be positively identified. These triterpenoids are generally absent from non-evaporitic sediments which contain essentially aromatic triterpenoids resulting from microbially mediated aromatization processes starting in ring A (or in ring B when preceded by the loss of ring A). The uncommon transformations undergone by higher plant triterpenes in the highly anoxic sediments from Sainte-Cecile are specific for each series of triterpenes (i.e., oleanane, ursane, lupane) and are probably linked with the rapid disappearance of the functionality located in ring A by reduction or by the incorporation of the triterpenes in S-rich macromolecules by reaction with inorganic S species. These biological markers represent new source parameters which may be quite useful as indicators of terrestrial inputs in evaporitic deposits. 33 refs., 10 figs.

    Gas-diffusion microextraction (GDME) was applied to the extraction of vicinal diketones in bread samples aimed at the determination of these compounds by high-performance liquid chromatography with ultraviolet detection (HPLC-UV). For the first time, GDME was used for direct chemical determination in solid samples, i.e. avoiding any sample preparation prior to extraction. Different extraction parameters were studied and optimized, namely temperature, time and chemical composition of the acceptor solution where o-phenylenediamine was used as a derivatizing agent, originating quinoxalines that could be determined at 315 nm. GDME demonstrated to be a good tool for the sampling of volatile compounds in solid samples with suitable method features for butane-2,3-dione (diacetyl, DC), pentane-2,3-dione (PN) and hexane-2,3-dione (HX): low LODs (6.0, 8.6 and 12 μg kg(-1), for DC, PN and HX respectively) and LOQs (20, 29 and 38 μg kg(-1), for DC, PN and HX respectively), r(2) above 0.990, and CV around 5%. The developed methodology was applied to the determination of different bread samples and was used to reveal the decrease of α-diketones in bread during the timeframe of a week. PMID:25868491

    BACKGROUND 29% of women aged 30-39 report having had a mammogram though sensitivity and specificity are low. We investigate racial/ethnic differences in future mammography behavior among women who had a baseline screening mammogram prior to age 40. METHODS Using 1994-2008 data from the Breast Cancer Surveillance Consortium (BCSC), we identified 29,390 women ages 35-39 with a baseline screening mammogram. We followed this cohort for two outcomes: (1) future BCSC mammography between ages 40-45; and (2) among those, delay in screening mammography until ages 43-45 compared to 40-42. Using adjusted log-linear models, we estimated the relative risk (RR) of these outcomes by race/ethnicity, while also considering the impact of false positive/true negative (FP/TN) baseline mammography results on these outcomes. RESULTS Relative to non-Hispanic white women, Hispanic women had an increased risk of no future BCSC mammography (RR: 1.21, 95% confidence interval (CI): 1.13-1.30); Asian women had a decreased risk (RR: 0.67, 95% CI: 0.61-0.74). Women with a FP, compared to TN, had a decreased risk of no future BCSC mammography (RR: 0.89, 95% CI: 0.85-0.95). Among those with future BCSC screening mammography, African American women were more likely to delay the timing (RR: 1.26, 95% CI: 1.09-1.45). The interaction between race/ethnicity and FP/TN baseline results was not significant. CONCLUSIONS Race/ethnicity is differentially associated with future BCSC mammography and the timing of screening mammography after age 40. IMPACT These findings introduce the need for research that examines disparities in lifetime mammography use patterns from the initiation of mammography screening. PMID:21242330

    The failure of neural tube closure during early embryogenesis results in a range of neural tube defects (NTD), the most common of which is spina bifida. The role of folic acid in reducing the rate of NTD has been well-established. Three recent cases of infants with NTD inspired this investigative study into the level of awareness and knowledge of folic acid and its function in the prevention of NTD among Israeli women. Of 920 women interviewed, only 51 (5.5%) had heard of folic acid, and 27 (2.8%) were reported to have taken it. The source of information and the motivation for self-medication were also explored with regard to socioeconomic and health profile. Awareness of folic acid was significant among women aged 17-29 years (P = 0.005) and those aged 30-39 years (P = 0.009), and among semireligious and nonreligious women (P = 0.008 and 0.01, respectively). Among women who were aware of folic acid, only nonreligious women tended to take it. No correlation was found between folic acid intake and age, religiosity, nationality, number of pregnancies, and health status among women who were aware of folic acid intake. The poor level of awareness, evident in our study, demands that the medical community broadcast the benefit of folic acid. Furthermore, government health initiatives, such as the addition of folic acid to flour preparations, may effectively ensure its appropriate daily intake. These improved education and prevention programs may forcibly reduce the rate of NTD-affected pregnancies.

    This study investigates family meals among mothers and explores associations between eating with family and sociodemographic characteristics, body mass index, and eating practices. A population-based cross-sectional study, using complex cluster-sampling, was conducted in the city of Santos, Brazil with 439 mothers. Frequency of family meals was assessed by asking if mothers did or did not usually have a) breakfast, b) lunch, and c) dinner with family. Linear regression analyses were conducted for the number of meals eaten with family per day and each of the potential explanatory variables, adjusting for the mother's age. Poisson regression with robust variance was used to analyze each factor associated with eating with family as classified categorically: a) sharing meals with family, b) not eating any meals with family. Only 16.4% (n = 72) of participants did not eat any meals with family. From the 83.6% (n = 367) of mothers that had at least one family meal per day, 69.70% (n = 306) ate dinner with their families. Mothers aged ≥40 years reported significantly fewer meals eaten with family compared to mothers aged 30-39 years (β: -0.26, p = 0.04). Having family meals was 54% more prevalent among mothers with ≥12 years of education (PR for no meals eaten with family: 0.54, 95% CI: 0.30; 0.96, p = 0.03), when compared to mothers with less than nine years of education. Eating no meals with family was 85% more prevalent among mothers who reported that eating was one of the biggest pleasures in their lives (PR: 1.85, 95% CI: 1.21; 2.82, p = 0.004). We suggest the need for further research investigating the effects of family meals on mothers' health through nutritional and phenomenological approaches. PMID:26994738

    The sound in classical orchestral music is louder than noise emissions allowed by national rules in industry. We wanted to assess the audiologic status of professional musicians at different ages of their careers and to look for a coherence of declined hearing ability and the sound emissions in order to substantiate advices for hearing protection and occupational medicine in musicians. Data from questionnaires (anamnestic data on sound exposure in profession and leisure times, use of hearing protection, self-evaluation of hearing function and hearing deficits), audiometric data and amplitudes of OAE were evaluated from 109 professional musicians aged 30-69 years from three major German orchestras and from 110 students of an academy of music (aged 11-19 years). Sound emissions of the whole orchestra and of single instruments/instrument groups were measured at the orchestra stages and pits during rehearsals and performances. None of the musicians was engaged in noisy hobbies and only a few used hearing protectors regularly. More than 50% of the musicians had a hearing loss of 15 dB(A) and more. Highest losses were found among the strings and the brass players. DPOAE amplitudes coincidently declined with the duration of performing music in the orchestras. Professional musicians aged older than 60 years had a significantly greater hearing loss at 4 and 6 kHz than those aged 30-39 years. Among the strings in one orchestra a dominant hearing deficit in the left ears was observed. Musicians need the same health care for their hearing as workers in noisy industry. A better education on the hearing hazards (use of hearing protectors) as well as sound protection in the rehearsal rooms is necessary. Hearing loss in professional musicians should be accepted as an occupational disease.

    Rapeseed (Brassica napus L.) has been cultivated for biodiesel production worldwide. Winter rapeseed is commonly grown in the southern part of Korea under a rice-rapeseed double cropping system. In this study, a greenhouse pot experiment was conducted to assess the effects of rapeseed residue applied as a green manure alone or in combinations with mineral N fertilizer on Cd and Pb speciation in the contaminated paddy soil and their availability to rice plant (Oryza sativa L.). The changes in soil chemical and biological properties in response to the addition of rapeseed residue were also evaluated. Specifically, the following four treatments were evaluated: 100% mineral N fertilizer (N100) as a control, 70% mineral N fertilizer+rapeseed residue (N70+R), 30% mineral N fertilizer+rapeseed residue (N30+R) and rapeseed residue alone (R). The electrical conductivity and exchangeable cations of the rice paddy soil subjected to the R treatment or in combinations with mineral N fertilizer treatment, N70+R and N30+R, were higher than those in soils subjected to the N100 treatment. However, the soil pH value with the R treatment (pH 6.3) was lower than that with N100 treatment (pH 6.9). Use of rapeseed residue as a green manure led to an increase in soil organic matter (SOM) and enhanced the microbial populations in the soil. Sequential extraction also revealed that the addition of rapeseed residue decreased the easily accessible fraction of Cd by 5-14% and Pb by 30-39% through the transformation into less accessible fractions, thereby reducing metal availability to the rice plant. Overall, the incorporation of rapeseed residue into the metal contaminated rice paddy soils may sustain SOM, improve the soil chemical and biological properties, and decrease the heavy metal phytoavailability.

    Coca-Cola was invented in May 1886 in Atlanta, Georgia by a pharmacist who, by accident or design, mixed carbonated water with the syrup of sugar, phosphoric acid, caffeine, and other natural flavors to create what is known as "the world's favorite soft drink." Coca-Cola is currently sold in more than 200 countries and in early 2000, the company sold its 10 billionth unit case of Coca-Cola branded products. Given the worldwide consumption of Coca-Cola, a project of experimental bioassays to study its long-term effects when administered as substitute for drinking water on male and female Sprague-Dawley rats was planned and executed. The objective of the project was to study whether and how long-term consumption of Coca-Cola affects the basic tumorigram of test animals. The bioassays were performed on rats beginning at different ages, namely: (a) on males and females exposed since embryonic life or from 7 weeks of age; and (b) on males and females exposed from 30, 39, or 55 weeks of age. Overall, the project included 1999 rats. During the biophase, data were collected on fluid and feed consumption, body weight, and survival. Animals were kept under observation until spontaneous death and underwent complete necropsy. The results indicate: (a) an increase in body weight in all treated animals; (b) a statistically significant increase of the incidence in females, both breeders and offspring, bearing malignant mammary tumors; (c) a statistically significant increase in the incidence of exocrine ademonas of the pancreas in both male and female breeders and offspring; and (d) an increased incidence, albeit not statistically significant, of pancreatic islet cell carcinomas in females, a malignant tumor which occurs very rarely in our historical controls. On the basis of the results of this study, excessive consumption of regular soft-drinks should be generally discouraged, in particular for children and adolescents.

    Chemotherapy (CT) is widely used for neuroendocrine tumours (NETs), but there are no validated biomarkers to predict response. The Ki-67 proliferation index has been proposed as a means of selecting patients for CT, but robust data are lacking. The aim of this study was to investigate the relationship between response to chemotherapy and Ki-67 in NET. We reviewed data from 222 NET patients treated with CT. Tumours were graded according to Ki-67 index: G1 ≤2%, G2 3-20% and G3 >20%. Response was assessed according to RECIST and survival calculated from start of chemotherapy to death. To explore Ki-67 as a marker of response, we calculated the likelihood ratio and performed receiver operating characteristic analysis. Overall, 193 patients had a documented Ki-67 index, of which 173 were also evaluable for radiological response: 10% were G1, 46% G2 and 43% G3; 46% were pancreatic NET (PNET). Median overall survival was 22.1 months. Overall response rate was 30% (39% in PNET vs 22% in non-PNET) and 43% of patients had stable disease. Response rate increased with grade: 6% in G1 tumours, 24% in G2 and 43% in G3. However, maximum likelihood ratio was 2.3 at Ki-67=35%, and the area under the ROC curve was 0.60. As reported previously, a high Ki-67 was an adverse prognostic factor for overall survival. In conclusion, response to CT increases with Ki-67 index, but Ki-67 alone is an unreliable means to select patients for CT. Improved methods to stratify patients for systemic therapy are required.

    This article examines the constraints of antiretroviral (ARV) uptake in the villages of Thamaga, Kumakwane, Mankgodi and Gakgatla which are in the Kweneng District of Botswana. The social interactionist approach and theories of health behaviour provided the theoretical basis of the study. Data were obtained by using interviewer-administered questionnaires which were applied to a sample of 145 respondents and 61 people living with HIV/AIDS in the four villages. The results of the study showed that people aged 30-39 years represented the highest proportion of the persons on ARV treatment in the villages. Some of the people living with HIV believed that ARV therapy could better their lives during the initial stages of introduction, but with time, they lost hope and gave up the treatment. Culturally, parents and children in the villages do not discuss sexual matters at home and it was found in the study that there was little communication between parents and children on AIDS and ARV issues. Some churches in the area discouraged the use of ARV. There were also traditional doctors who made their patients mix traditional herbs treatment with ARV treatment. Distance, travel costs, cultural beliefs, stigma and discrimination among others were found to be important socio-economic factors inhibiting ARV uptake. Even though there were constraints on ARV uptake in the villages, efforts were being made by Government and non-governmental organizations to overcome them. The Ministry of Health provided information and education to the public using its strategy known as Information, Education and Communication. Nurses, doctors and chiefs taught people at kgotlas (traditional courts) in the villages about the dangers of the epidemic. Free HIV testing, ARVs and condoms were provided to the villagers. The outlook for ARV uptake looks generally promising for the future. However, if HIV/AIDS is to be contained, sexual behaviour of people in the villages needs to change.

    Small piscivores are regarded as important regulators of the composition of coral reef fish communities, but few studies have investigated their predatory ecology or impact on assemblages of juvenile fishes. This study investigated the foraging ecology of a common coral reef predator, the dottyback Pseudochromis fuscus, using underwater focal animal observations. Observations were conducted at two times of year: the summer, when recruit fishes were an available food item and winter, when remaining juveniles had outgrown vulnerability to P. fuscus. During the summer, P. fuscus directed 76% of its strikes at invertebrates and 24% at recruiting juvenile fishes. When striking at fishes, P. fuscus exhibited two distinct feeding modes: an ambush (26% successful) and a pursuit mode (5% successful). Predator activity in the field peaked at midday, averaging 2.5 captures h-1 of juvenile fishes. Monitoring of activity and foraging in the laboratory over 24-h periods found that P. fuscus was a diurnal predator and was active for 13 h d-1 during the summer. The number of hours during which foraging was recorded differed greatly among individuals ( n = 10), ranging from 4 to 13 h. The number of predatory strikes did not increase with standard length, but the success rate and consumption rate of juvenile fishes did increase with size. Estimated hourly mortality on juvenile fish ranged from 0.49 fish h-1 in small P. fuscus individuals (30-39 mm standard length, SL; equating to 6.3 per 13 h day) to 2.4 fish h-1 in large P. fuscus individuals (55-65 mm SL; 30.6 per 13 h day). During the winter, P. fuscus struck at invertebrates with a similar rate to the summer period. These observations of the predatory ecology of P. fuscus support the hypothesis that in coral reef systems, small piscivores, because of their high metabolism and activity, are probably important regulators of coral reef fish community composition.

    Although the so called "green islands" of the semi-arid Brazilian "Nordeste" are economically, socially, and ecologically important. relatively little is known about their biodiversity. We present the results of the first survey of the ground-dwelling ant fauna of a secondary forest in the Serra de Baturité (4 degrees 05'-4 degrees 40' S / 38 degrees 30'-39 degrees 10' W), among the biggest of the moist, montane forests of the state of Ceará, Brazil. From February to March 2001, samples were taken every 50 m along twelve 200 m transects, each separated from the others by at least 50 m and cut on either side of a recreational trail. Where possible, two transects were cut from the same starting point on the trail, one on either side. At each sample site two methods were used, as recommended in the ALL. protocol: a pitfall trap and the treatment of 1 m2 of leaf litter with the Winkler extractor. The myrmecofauna of the Serra de Baturité is quite diverse: individuals from 72 species, 23 genera, and six subfamilies were collected. The observed patterns of specific richness show the same tendencies noted in other tropical regions, particularly the frequency of capture distribution with many rare and few abundant species. Differences with the Atlantic and Amazonian forests were also observed, especially the relative importance of the Ponerinac and Formicinae subfamilies, indicating a possible influence of the surrounding "caatinga" (savanna-like ecosystem) on the myrmecofauna of the moist, montane forest.

    Foraging honeybees are subjected to considerable variations of microclimatic conditions challenging their thermoregulatory ability. Solar heat is a gain in the cold but may be a burden in the heat. We investigated the balancing of endothermic activity with radiative heat gain and physiological functions of water foraging Apis mellifera carnica honeybees in the whole range of ambient temperatures (T(a)) and solar radiation they are likely to be exposed in their natural environment in Middle Europe. The mean thorax temperature (T(th)) during foraging stays was regulated at a constantly high level (37.0-38.5 °C) in a broad range of T(a) (3-30 °C). At warmer conditions (T(a)=30-39 °C) T(th) increased to a maximal level of 45.3 °C. The endothermic temperature excess (difference of T(body)-T(a) of living and dead bees) was used to assess the endogenously generated temperature elevation as a correlate of energy turnover. Up to a T(a) of ∼30 °C bees used solar heat gain for a double purpose: to reduce energetic expenditure and to increase T(th) by about 1-3 °C to improve force production of flight muscles. At higher T(a) they exhibited cooling efforts to get rid of excess heat. A high T(th) also allowed regulation of the head temperature high enough to guarantee proper function of the bees' suction pump even at low T(a). This shortened the foraging stays and this way reduced energetic costs. With decreasing T(a) bees also reduced arrival body weight and crop loading to do both minimize costs and optimize flight performance. PMID:20705071

    Sour cherry (Prunus cerasus L.) scion cv. Montmorency and rootstock cv. Gisela 6 (P. cerasus x P. canescens) were transformed using Agrobacterium tumefaciens strain EHA105:pBISN1 carrying the neomycin phosphotransferase gene (nptII) and an intron interrupted ss-glucuronidase (GUS) reporter gene (gusA). Whole leaf explants were co-cultivated with A. tumefaciens, and selection and regeneration of transformed cells and shoots of both cultivars was carried out for 12 weeks on selection medium containing 50 mg l(-1) kanamycin (Km) and 250 mg l(-1) timentin. These media were [Quoirin and Lepoivre (Acta Hortic 78:437-442, 1977)] supplemented with 0.5 mg l(-1) benzylaminopurine (BA) + 0.05 mg l(-1) indole-3-butyric acid (IBA), and woody plant medium [Lloyd and McCown (Proc Int Plant Prop Soc 30:421-427, 1980)] containing 2.0 mg l(-1) BA + 1.0 mg l(-1) IBA for cv. Montmorency and cv. Gisela 6, respectively. Seven out of 226 (3.1%) explants of cv. Montmorency and five out of 152 (3.9%) explants of cv. Gisela 6 produced 30/39 GUS- and PCR-positive shoots from the cut midribs via an intermediate callus. Southern analysis of the GUS- and PCR-positive transformants confirmed stable integration of the transgenes with 1-3 copy numbers in the genomes of seven lines of cv. Montmorency and five of cv. Gisela 6. The selected transformants have a normal phenotype in vitro. PMID:16369768

    Field microplots were treated with 141 and 282 ppm fensulfothion and 37.1 and 74.2 ppm fensulfothion sulfone. These concentrations are equivalent to field treatment rates of 8.48 and 16.96 kg AI/ha, fensulfothion, and 2.23 and 4.47 kg AI/ha, fensulfothion sulfone, respectively, for banded application (10 cm wide, rows 80 cm apart). The half-lives in a sandy loam soil were 30-39 and 14-23 days, respectively. Fensulfothion sulfone and sulfide were the main derivatives found in fensulfothion treated soil. The maximum levels of these derivatives were 21.22 and 22.95 ppm, respectively for the 8.48 kg/ha treatment and 33.90 and 42.45 ppm, respectively, for the higher treatment, which occurred between 30-60 days. Carrots appeared to take up more fensulfothion from soil than rutabagas or radishes. The residue levels at harvest decreased in the order carrot peel greater than pulp greater than rutabagas root greater than peel greater than pulp. Residue levels of fensulfothion and sulfone in radishes were similar to those found in rutabagas. The ratio sulfoxide/sulfone in rutabagas ranged from 0.4-1.5 and in carrots from 1.7-7.6. This phenomenon is thought to be due to oxidative enzyme systems present in rutabagas. Dimethyl phosphorothioic acid, but not dimethyl phosphoric acid was detected (max. 1.33 ppm) in some rutabagas samples but not in carrots.

    Prescription opiate use and abuse has increased dramatically over the past two decades, including increased use in adolescent populations. Recently, it has been proposed that use during this critical period may affect future offspring even when use is discontinued prior to conception. Here, we utilize a rodent model to examine the effects of adolescent morphine exposure on the reward functioning of the offspring. Female Sprague Dawley rats were administered morphine for 10 days during early adolescence (post-natal day 30-39) using an escalating dosing regimen. Animals then remained drug free until adulthood at which point they were mated with naïve males. Adult offspring (F1 animals) were tested for their response to morphine-induced (0, 1, 2.5, 5, and 10 mg/kg, s.c.) conditioned place preference (CPP) and context-independent morphine-induced sensitization. Naïve littermates were used to examine mu opiate receptor expression in the nucleus accumbens and ventral tegmental area. Results indicate that F1 females whose mothers were exposed to morphine during adolescence (Mor-F1) demonstrate significantly enhanced CPP to the lowest doses of morphine compared with Sal-F1 females. There were no differences in context-independent sensitization between maternal treatment groups. Protein expression analysis showed significantly increased levels of accumbal mu opiate receptor in Mor-F1 offspring and decreased levels in the VTA. Taken together, these findings demonstrate a shift in the dose response curve with regard to the rewarding effects of morphine in Mor-F1 females which may in part be due to altered mu opiate receptor expression in the nucleus accumbens and VTA.

    Background The proportion of people living with HIV/AIDS in the ageing population (>50 years) is increasing. We aim to explore the relationship between older age and treatment outcomes in HIV-positive persons from the Asia-Pacific region. Methods Patients from the Australian HIV Observational Database (AHOD) and the TREAT Asia HIV Observational Database (TAHOD) were included in the analysis. We used survival methods to assess the association between older age and all-cause mortality, as well as time-to treatment modification. We used regression analyses to evaluate changes in CD4 counts after combination antiretroviral therapy (cART) initiation and determined the odds of detectable viral load, up to 24 months of treatment. Results A total of 7142 patients were included in these analyses (60% TAHOD, 40% AHOD), of which, 25% were >50 years old. In multivariable analyses those aged >50 were at least twice as likely to die as those aged 30-39 years [HR (50-59 years): 2.27, 95% CI: 1.34-3.83; HR (>60years) 4.28, 95% CI: 2.42-7.55]. The effect of older age on CD4 count changes was insignificant (p-trend=0.06). The odds of detectable viral load after cART initiation decreased with age (p-trend=<0.0001). The effect of older age on time-to first treatment modification was insignificant (p-trend=0.21). We found no statistically significant differences in outcomes between AHOD and TAHOD participants for all endpoints examined. Conclusion The associations between older age and typical patient outcomes in HIV-positive patients from the Asia-Pacific region are similar in AHOD and TAHOD. Our data indicate that ‘age-effects’ traverse the resource-rich and resource-limited divide and indicate that future ageing-related findings might be applicable to each setting. PMID:25407085

    Objectives Chlorination destroys pathogens in swimming pool water, but by-products of chlorination can cause human illness. We investigated outbreaks of ocular and respiratory symptoms associated with chlorinated indoor swimming pools at two hotels. Measurements We interviewed registered guests and companions who stayed at hotels X and Y within 2 days of outbreak onset. We performed bivariate and stratified analyses, calculated relative risks (RR), and conducted environmental investigations of indoor pool areas. Results Of 77 guests at hotel X, 47 (61%) completed questionnaires. Among persons exposed to the indoor pool area, 22 (71%) of 31 developed ocular symptoms [RR = 24; 95% confidence interval (CI), 1.5–370], and 14 (45%) developed respiratory symptoms (RR = 6.8; 95% CI, 1.0–47) with a median duration of 10 hr (0.25–24 hr). We interviewed 30 (39%) of 77 registered persons and 59 unregistered companions at hotel Y. Among persons exposed to the indoor pool area, 41 (59%) of 69 developed ocular symptoms (RR = 24; 95% CI, 1.5–370), and 28 (41%) developed respiratory symptoms (RR = 17; 95% CI, 1.1–260) with a median duration of 2.5 hr (2 min–14 days). Four persons sought medical care. During the outbreak, the hotel X’s ventilation system malfunctioned. Appropriate water and air samples were not available for laboratory analysis. Conclusions and relevance to professional practice Indoor pool areas were associated with illness in these outbreaks. A large proportion of bathers were affected; symptoms were consistent with chloramine exposure and were sometimes severe. Improved staff training, pool maintenance, and pool area ventilation could prevent future outbreaks. PMID:17384776

    Background and objectives: Multiple Sclerosis (MS) is a chronic recurrent neurological disease that affects the Central Nervous System. This study aims to determine epidemiological factors that affect the appearance of MS, such as: incidence, prevalence, mortality, case appearance in accordance with the disease phase RRMS, SPMS, PPMS, gender, age, age group, and EDSS. Materials and methods: Deals with analyzing diagnosed and treated patients in the Clinic of Neurology in Prishtina during the period of 2003-2012. The research was conducted through a questionnaire applied in the diagnosed cases of MS. Information on patients was gathered from: history of illness, discharge reports and other relevant documents on MS illness. Clinical and epidemiological-descriptive study methods were used. The acquired results are shown through tables, graphics. Statistical processing was conducted with Microsoft Office Excel. Results: From the total number of doubtful hospitalized cases of demyelinization (644) in the Clinic of Neurology in Prishtina, 412 cases (64%) were diagnosed with MS. For the period of 2003–2012 the prevalence of MS has been 19.6 of patients in 100,000 inhabitants. MS incidence rate was 0.95 of patients in 100,000 inhabitants. MS mortality rate was 0.14 of deceased in 100,000 inhabitants. The ratio female – male is 2.3:1. A larger number of patients fall within the age group of 30-39 years-old. Clinical form trends: RRSM 72.3%, SPSM 22.6%, PPSM 5.1%. The rate of EDSS 78.3% (0–3.5), 14.9% (4–6.5), 6.8% (7–9). PMID:25568528

    In this study, we use a 1-D version of a climate-aerosol-chemistry model with both modal and sectional aerosol size representations to evaluate the impact of aerosol size representation on modeling aerosol-cloud interactions in shallow stratiform clouds observed during the 2nd Aerosol Characterization Experiment. Both the modal (with prognostic aerosol number and mass or prognostic aerosol number, surface area and mass, referred to as the Modal-NM and Modal-NSM) and the sectional approaches (with 12 and 36 sections) predict total number and mass for interstitial and activated particles that are generally within several percent of references from a high resolution 108-section approach.more » The modal approach with prognostic aerosol mass but diagnostic number (referred to as the Modal-M) cannot accurately predict the total particle number and surface areas, with deviations from the references ranging from 7-161%. The particle size distributions are sensitive to size representations, with normalized absolute differences of up to 12% and 37% for the 36- and 12-section approaches, and 30%, 39%, and 179% for the Modal-NSM, Modal-NM, and Modal-M, respectively. For the Modal-NSM and Modal-NM, differences from the references are primarily due to the inherent assumptions and limitations of the modal approach. In particular, they cannot resolve the abrupt size transition between the interstitial and activated aerosol fractions. For the 12- and 36-section approaches, differences are largely due to limitations of the parameterized activation for non-log-normal size distributions, plus the coarse resolution for the 12-section case. Differences are larger both with higher aerosol (i.e., less complete activation) and higher SO2 concentrations (i.e., greater modification of the initial aerosol distribution).« less

    The model of asbestos-related mesothelioma implies that the time since first exposure (latency) is the key determinant of subsequent risk. The role of recent exposure or stopping asbestos exposure, if any, is, however, open to discussion. A literature review was conducted to the end of 2010. In a cohort of 1966 Italian textile workers, the standardized mortality ratio, on the basis of 68 deaths from mesothelioma, was 6627 for workers employed only under the age of 30 years, 8019 for those employed both under the age of 30 years and at the age of 30-39 years, and 5891 for those employed both under the age of 30 years and at the age of 40 years or more. In a cohort of Italian asbestos cement workers, including 135 deaths from pleural cancer, compared with workers who had stopped exposure for 3-15 years, the relative risk (RR) was similar for those still employed (RR=0.67) and for those who had stopped for 30 years or more (RR=0.65). In a British case-control study, including 622 cases of mesothelioma and 1420 population controls, the RR substantially increased with increasing duration of exposure under the age of 30 years, but not with exposure at the age of more than 30 years. In the Great Britain Asbestos Workers Survey, including 649 deaths from mesothelioma compared with workers who were still employed and or had stopped for less than 10 years, the multivariate RRs were 0.90 10-20 years after stopping exposure and 0.99 both 20-30 and more than 30 years after stopping. There is consistent evidence showing that, for workers exposed in the distant past, the risk of mesothelioma is not appreciably modified by subsequent exposures, and that stopping exposure does not materially modify the subsequent risk of mesothelioma.

    Agonist concentration-response relationships at nicotinic postsynaptic receptors were established by measuring /sup 86/Rb/sup +/ efflux from acetylcholine receptor rich native Torpedo membrane vesicles under three different conditions: (1) integrated net ion efflux (in 10 s) from untreated vesicles, (2) integrated net efflux from vesicles in which most acetylcholine sites were irreversibly blocked with ..cap alpha..-bungarotoxin, and (3) initial rates of efflux (5-100 ms) from vesicles that were partially blocked with ..cap alpha..-bungarotoxin. Exposure to acetylcholine, carbamylcholine, suberyldicholine, phenyltrimethylammonium, or (-)-nicotine over 10/sup 8/-fold concentration ranges results in bell-shaped ion flux response curves due to stimulation of acetylcholine receptor channel opening at low concentrations and inhibition of channel function at 60-2000 times higher concentrations. Concentrations of agonists that inhibit their own maximum /sup 86/Rb/sup +/ efflux by 50% (K/sub B/ values) are 110, 211, 3.0, 39, and 8.9 mM, respectively, for the agonists listed above. For acetylcholine and carbamylcholine, K/sub B/ values determined from both 10-s and 15-ms efflux measurements are the same, indicating that the rate of agonist-induced desensitization increases to maximum at concentrations lower than those causing self-inhibition. For all partial and full agonists studied, Hill coefficients for self-inhibition are close to 1.0. Concentrations of agonists up to 8 times K/sub B/ did not change the order parameter reported by a spin-labeled fatty acid incorporated in Torpedo membranes. The authors conclude that agonist self-inhibition cannot be attributed to a general nonspecific membrane perturbation. Instead, these results are consistent with a saturable site of action either at the lipid-protein interface or on the acetylcholine receptor protein itself.

    While decreasing trend in gender differences in alcohol use disorders was reported in Western countries, the change in Asian countries is unknown. This study aims to explore the shifts in gender difference in alcohol abuse (AA) and dependence (AD) in Korea. We compared the data from two nation-wide community surveys to evaluate gender differences in lifetime AA and AD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Face-to-face interviews using the Composite International Diagnostic Interview (CIDI) were applied to all subjects in 2001 (n=6,220) and 2011 (n=6,022). Male-to-female ratio of odds was decreased from 6.41 (95% CI, 4.81-8.54) to 4.37 (95% CI, 3.35-5.71) for AA and from 3.75 (95% CI, 2.96-4.75) to 2.40 (95% CI, 1.80-3.19) for AD. Among those aged 18-29, gender gap even became statistically insignificant for AA (OR, 1.59; 95% CI, 0.97-2.63) and AD (OR, 1.18; 95% CI, 0.80-2.41) in 2011. Men generally showed decreased odds for AD (0.55; 95% CI, 0.45-0.67) and women aged 30-39 showed increased odds for AA (2.13; 95% CI 1.18-3.84) in 2011 compared to 2001. Decreased AD in men and increased AA in women seem to contribute to the decrease of gender gap. Increased risk for AA in young women suggests needs for interventions.

    Therapeutic hypothermia (TH) improves the outcomes of cardiac arrest (CA) survivors. The aim of this study was to evaluate retrospectively the efficacy and safety of an immediate prehospital cooling procedure implemented just after the return of spontaneous circulation with a prehospital setting. During 30 months, the case records of comatose survivors of out-of-hospital CA presumably due to a cardiac disease were studied. A routine protocol of immediate postresuscitation cooling had been tested by an emergency team, which consisted of an infusion of large-volume, ice-cold intravenous saline. We decided to assess the efficacy and tolerance of this procedure. A total of 99 patients were studied; 22 were treated with prehospital TH, and 77 consecutive patients treated with prehospital standard resuscitation served as controls. For all patients, TH was maintained for 12 to 24 hours. The demographic, clinical, and biological characteristics of the patients were similar in the 2 groups. The rate of patients with a body temperature of less than 35 degrees C upon admission was 41% in the cooling group and 18% in the control group. Rapid infusion of fluid was not associated with pulmonary edema. After 1 year of follow-up, 6 (27%) of 22 patients in the cooling group and 30 (39%) of 77 patients in the control group had a good outcome. Our preliminary observation suggests that in comatose survivors of CA, prehospital TH with infusion of large-volume, ice-cold intravenous saline is feasible and can be used safely by mobile emergency and intensive care units.

    This paper presents the results of mercury fractionation in muscle samples of dourada (Brachyplatystoma rousseauxii) from the JIRAU Hydroelectric Power Plant in the Madeira River Basin in the Amazon region of Brazil. The proteome of the dourada muscle was separated by two-dimensional polyacrylamide gel electrophoresis (2D PAGE). The mercury present in the protein spots was determined by graphite furnace atomic absorption spectrometry (GFAAS) after acid mineralisation in an ultrasound bath. The protein spots in which the presence of mercury was detected were characterised by electrospray ionisation tandem mass spectrometry (ESI-MS/MS) after tryptic digestion. The GFAAS determinations indicated that 65% of the mercury was linked to the protein fraction with a molar mass (Mm) of less than 90 kDa. The mercury concentrations in the seven spots in which this protein fraction was present were in the range of 11.40-35.10 μg kg(-1). Based on the mercury concentrations, it was possible to estimate that the protein spots contained approximately 1-3 mercury atoms per protein molecule. The ESI-MS/MS analysis allowed characterisation of the seven protein spots as the following proteins: protein NLRC5 (molar mass=18.10, pI=6.30); 39S ribosomal protein L36 mitochondrial (molar mass=15.40, pI=8.23); N-alpha-acetyltransferase 20 (Mm=15.95, pI=8.80); Mth938 domain-containing protein (Mm=15.01, pI=9.60); ubiquitin-40S ribosomal protein S27a (Mm=9.80, pI=7.60); parvalbumin alpha (Mm=12.40, pI=3.80) and parvalbumin beta (Mm=13.10, pI=3.45).

    Shrub-induced soil property spatial heterogeneity is common in arid and semi-arid ecosystems and aids desertified land restoration. However, the effectiveness of this technique may rely on the plant species used and the habitat conditions present. To assess the degree to which planting two native species, Haloxylon salicornicum and Calligonum polygonoides, facilitates degraded land restoration, soil and herbaceous plant community properties were measured 7 years after planting. Soil samples were extracted at two depths (0-5 and 5-20 cm) from three sub-habitats, i.e., under the shrub canopy, from alleys between shrubs and from the open area. Shrub planting increased the quantity of silt + clay content (30-39 %); enhanced water holding capacities (24-30 %); increased the levels of organic carbon (48-69 %), available nitrogen (31-47 %), available phosphorus (32-41 %), and electrical conductivity (21-33 %); and decreased the pH (7-12 %) and bulk density levels (5-6 %) in the surface layer of soils beneath the canopy. Soil property changes were more significant at the surface (0-5 cm) than in the deeper layer (5-20 cm), and were more pronounced under H. salicornicum than under C. polygonoides. Furthermore, the density and biomass levels of herbaceous plants were 1.1 to 1.2 and 1.4 to 1.6 times greater, respectively, in the shrub alleys than in open area. H. salicornicum induced more robust soil amelioration and herbaceous plant facilitative properties than did C. polygonoides. Artificially planting these shrubs may thus be employed to restore degraded areas of arid regions. PMID:25239772

    Lipid parameters (cholesterol CH, HDL-, LDL-cholesterol, triacylglycerols TG, atherogenic index AI) were estimated in four age groups of vegetarians, 82 males and 80 females, aged 15 to 60 years. The period of consumption of vegetarian food was 1.4 to 1.9 years for adolescents (15-18 years old) or 2.4 to 5.4 years for adults (age groups 19-29 years, 30-39 years and 40-60 years). Lacto-vegetarians constituted one half of females and one third of males. Vitamin C content, lipid peroxidation levels (conjugated dienes, CD) and the activities of catalase (CAT) and glutathione peroxidase (GSH-Px) were estimated in the oldest age group of males and females. Low levels of TG and glutathione peroxidase (GSH-Px) were estimated in the oldest age group of males and females. Low levels of TG and CH (in the lower half of the reference range), low calculated values of LDL-CH and AI, as well as values of HDL-CH in the upper region of the standard risk zone or over 1.4 mmol/l (reduced risk level) in males and females of all age groups are the positive factors of vegetarian nutrition in prevention of atherosclerosis. High levels of vitamin C in blood, absence of obesity and low blood pressure should be mentioned here as additional positive factors as well. When considered as a single isolated factor, the nearly significantly elevated values of CD (linked to increased intake of unsaturated fatty acids) could be a negative factor of vegetarian nutrition.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background and Objectives Atrial fibrillation (AF) is a common arrhythmia that is known as an important independent risk factor for stroke. However, limited information is available on AF in Korea. This study evaluated the incidence of AF, its associated co-morbidities and risk factors for AF in Korea. Subjects and Methods The National Health Insurance Service database between 2002 and 2010 was used in the study. Individuals<30 years old and those diagnosed with AF between 2002 and 2004 were excluded. Hazard ratios (HRs) according to co-morbidities and risk factors for AF were determined using a Cox proportional hazard model. Population attributable fractions (PAFs) of AF risk factors were determined. Results During a 6-year follow-up period, 3517 (1.7%) developed AF. The incidence rates in men and women aged 30-39 years were 0.82 and 0.55 per 1000 person-years, respectively; the incidence rates further increased with age to 13.09 and 11.54 per 1000 person-years in men and women aged≥80 years, respectively. The risk factors for incident AF were age, sex, body mass index (BMI), hypertension, ischemic heart disease (IHD) and heart failure. After adjusting for variables related to AF, the risk of AF was significantly associated with hypertension (HR 1.667), IHD (HR 1.639), heart failure (HR 1.521), and the PAFs for age, sex, BMI, hypertension, IHD, heart failure and diabetes mellitus were 30.6%, 10.1%, 3.4%, 16.6%, 8.2%, 5.3% and 0.8%, respectively. Conclusion Incidence of AF increased with age and was higher in men than in women. A larger proportion of AF events was attributable to hypertension than to other co-morbidities. PMID:27482260

    The prevalence of Helicobacter pylori infection in Indonesia is still controversial and mainly investigated in the largest ethnic group, Javanese. We examined the prevalence of H. pylori infection using four different tests including culture, histology confirmed by immunohistochemistry and rapid urease test. We also analyzed risk factors associated with H. pylori infection in five largest islands in Indonesia. From January 2014-February 2015 we consecutively recruited a total of 267 patients with dyspeptic symptoms in Java, Papua, Sulawesi, Borneo and Sumatera Island. Overall, the prevalence of H. pylori infection was 22.1% (59/267). Papuan, Batak and Buginese ethnics had higher risk for H. pylori infection than Javanese, Dayak and Chinese ethnics (OR = 30.57, 6.31, 4.95; OR = 28.39, 5.81, 4.61 and OR = 23.23, 4.76, 3.77, respectively, P <0.05). The sensitivity and specificity for RUT and culture were 90.2%, 92.9% and 80.5%, 98.2%, respectively. The patients aged 50-59 years group had significantly higher H. pylori infection than 30-39 years group (OR 2.98, P = 0.05). Protestant had significantly higher H. pylori infection rate than that among Catholic (OR 4.42, P = 0.008). It was also significantly lower among peoples who used tap water as source of drinking water than from Wells/river (OR 9.67, P = 0.03). However only ethnics as become independent risk factors for H. pylori infection. Although we confirmed low prevalence of H. pylori in Javanese; predominant ethnic in Indonesia, several ethnic groups had higher risk of H. pylori infection. The age, religion and water source may implicate as a risk factor for H. pylori infection in Indonesia.

    This article discusses changing marriage, divorce, and remarriage patterns in China. The State Statistical Bureau reports that changing life style patterns will impact on the education of children and difficulties of housing and employment of single women, with or without children. Economic development has resulted in the elimination of poverty among over 20 million persons. Early marriage among males aged 15-21 years and females aged 15-19 years declined during 1990-96. The average age at first marriage increased by 2.0 years for males and 0.7 years for females during 1990-96. Average age at first marriage varies with level of economic development and location. Chinese families for centuries maintained arranged marriages. Marriage patterns have been influenced by customs from outside China. Couples use divorce as a means of settling disputes and focus on the quality of married life. Western culture has contributed to more frequent extramarital love affairs and the disintegration of many families. The basic foundation of marriage has weakened. The divorce rate rose during 1990-96. The highest rate of divorce by age was among persons aged 30-39 years in 1996, and among persons aged 50-59 years in 1990. The highest divorce rates by educational status were among illiterates and semiliterates in 1990, and among high school educated in 1996. Urban population had a higher divorce rate than rural population. Remarriage is gaining in popularity. Remarriages rose from 500,000 to 862,000 during 1985-95. The percentage of remarriages rose, especially among persons aged over 50 years.

    Background: Advanced paternal and/or maternal age is a classic risk factor for Down syndrome. The aim of the study was to investigate the frequency of Down syndrome types in children and its association with maternal and paternal age in Bosnia and Herzegovina. Subjects and Methods: The cross sectional, observational study included 127 children, 49 girls and 78 boys, aged 1-180 months suspected to have Down syndrome, admitted to the Centre for Genetics, Faculty of Medicine University of Sarajevo, for cytogenetic analysis and differential diagnosis of Down syndrome during the period from January 2010 to May 2015. Standard method of 72 hours cultivation of peripheral blood lymphocytes has been applied. The accepted level of statistical significance was p<0.05. Study Results: The most common type of Down syndrome was standard trisomy (86.6%), comparing to translocation and mosaicism (7.1%; 6.3%, respectively). The highest frequency of Down syndrome cases was in mother and father’s group from 30-39 years old (57; 57 children, respectively) compared to mother and father’s groups with younger than 30 (44; 29, respectively) and 40 and older (26; 41, respectively). The significant difference was found in maternal age between translocation and mosaicism groups (p=0.036). Difference between parental years and type of Down syndrome was significant when Standard trisomy 21 and translocation (p=0.045), as well as mosaicism and translocation (p=0.036), were compared. Conclusion: The most common type of Down syndrome was standard trisomy 21, with highest occurrence in parents from 30 to 39 years old. Parents were the youngest in translocation group. Obtained results suggest that multidisciplinary approach to identifying the trigger for trisomy appearance and the influence of maternal age is required. PMID:27147778

The drug utilization for ED is very low. Also, studies describing the prescription pattern in ED are lacking. Materials and Methods: We conducted a retrospective cross-sectional observational study, including a drug utilization analysis, of 606 prescriptions as per the standard guidelines (WHO and STROBE). Results: Out of 606, 249 (41%) were from the age group of 30-39 years. Addictions were present in 388 (64%). Out of 606, 186 had urological, 154 had cardiovascular and 102 had psychological co-morbid disorders. Out of 348, 201 were prescribed Tadalafil (low dose) on a once daily basis. Out of 172, 121 were prescribed Sildenafil (high dose) on an ‘as and when required’ basis. Nutritional/ herbal supplements were prescribed in 126/606. The ratio of ‘Prescribed Daily Dose’ to ‘Defined Daily Dose’ of Tadalafil, Sildenafil, and Dapoxetine were 1.1, 1.3 and 1.5 respectively. Conclusion: Measures for de-addiction play an important role in the overall management of ED. The most common co-morbid disorders were urological, like BPH, LUTS, etc, followed by cardiovascular, psychological and diabetes. Overall, rational pharmacotherapy was observed. Tadalafil was the most commonly prescribed drug for ED. The main factor in the selection of a particular PDE5 inhibitor was its pharmacokinetics and cost. Udenafil, being the costliest, was the least prescribed. Dapoxetine was used in a significant number of individuals primarily for PE with ED. The combination of Papaverine, Chlorpromazine ± Alprostadil was used as intracavernosal injection in patients not responding to oral drugs. PMID:26393163

    PURPOSE This in-vitro study was designed to evaluate retention forces, microleakage and plastic deformation of a prefabricated 2-implant bar attachment system (SFI-Bar, Cendres+Métaux, Switzerland). MATERIALS AND METHODS Two SFI implant-adapters were torqued with 35 Ncm into two implant analogues. Before the tube bars were finally sealed, the inner cavity of the tube bar was filled with liquid red dye to evaluate microleakage. As tube bar sealing agents three different materials were used (AGC Cem (AGC, resin based), Cervitec Plus (CP; varnish) and Gapseal (GS; silicone based). Four groups with eight specimens each were tested (GS, GS+AGC, AGC, CP). For cyclic loading, the attachment system was assembled parallel to the female counterparts in a chewing simulator. The mean retention forces of the initial and final ten cycles were statistically evaluated (ANOVA, α≤.05). RESULTS All groups showed a significant loss of retention forces. Their means differed between 30-39 N initially and 22-28 N after 50,000 loading cycles. No significant statistical differences could be found between the groups at the beginning (P=.224), at the end (P=.257) or between the loss of retention forces (P=.288). Microleakage occurred initially only in some groups but after 10,000 loading cycles all groups exhibited microleakage. CONCLUSION Long-term retention forces of the SFI-Bar remained above 20 N which can be considered clinically sufficient. The sealing agents in this study are not suitable to prevent microleakage.

    Despite ERK1 and ERK2 were considered interchangeable isoforms for a long time, their roles are now emerging as only partially overlapping. We recently reported that the nucleocytoplasmic trafficking of GFP-tagged ERK1 is slower than that of ERK2, this difference being caused by a unique domain of ERK1 located at its N-terminus (ERK1-Nt). In the present report we further investigated this issue by asking which were the specific aminoacids involved in such process. By photobleaching strategy, we demonstrated that ERK1-Nt is a domain capable to slow down the nucleocytoplasmic shuttling rate even of a small cargo protein. ERK1-Nt was then dissected into three regions as follows: 1 (aa 1-9), 2 (aa 10-29) and 3, (aa 30-39) that were deleted or mutated at specific sites. Dynamic imaging assessment of the role played by each region in determining the shuttling rate revealed that: region 1 has no significant role, region 2 and specific aminoacids of region 3 (V{sub 31}, K{sub 33,} P{sub 36}) are critical, but singularly do not totally account for the difference in the shuttling rate between ERK1 and 2. Finally, we demonstrated that the nucleocytoplasmic shuttling rate of a passively diffusing protein (mRED) is inversely related to ERK1-Nt-GFP concentrations inside the cell, thus suggesting that ERK1-Nt-GFP occupies the nuclear pore perhaps because of an important affinity of ERK1-Nt for nucleoporins. In conclusion, ERK1-Nt is a domain able per se to confer a slower shuttling rate to a cargo protein. Specific regions within this domain were identified as responsible for this biophysical property.

    Background The process of atherogenicity is known to be influenced by exercise. However, appropriate exercise stimulus necessary to generate the response and adaptation in sedentary non-obese individuals has not yet been investigated. The purpose of the present study was to compare the effects of an 8-week continuous training and corresponding interval training on the atherogenic index of plasma in sedentary Nigerian males. Methods Overall, there were 54 male university students that participated in our study, which used a pretest- posttest control group design. Participants (18 males per group) were assigned into continuous, interval and control groups respectively. During the first two weeks, training was done 3 times weekly for 30 minutes each day, and was increased by 5 minutes every 2 weeks. Continuous training was done at 70-84% of heart rate reserve. Interval training was done at 70-84%/30-39% heart rate reserve in 1:2 minutes work/rest intervals, respectively. The control group did not participate in the training. Data collected were analysed using descriptive, paired t-test, analysis of covariance and Bonferroni post-hoc analysis. Results Young sedentary non-obese males were at high risk (atherogenic index of plasma > 0.24) of cardiovascular diseases/conditions. However, continuous training led to significant reductions (p = 0.002) in the atherogenic index of plasma. In contrast, non-significant increase (p = 0.084) followed interval training. After controlling for baseline values, only continuous training still had significant effects on atherogenic index of plasma when compared with other groups. Conclusions Continuous training of vigorous intensity is better than a corresponding interval training protocol as a natural anti-atherogenic method of reducing risk of cardiovascular event in sedentary non-obese males.
