    This report describes a video presentation designed to introduce science to middle and high school science classes as a field which is attractive to women. It is designed to facilitate thought and discussion on the issue of gender stereotypes and discrimination, and is intended for use as part of a curriculum plan which will discuss these issues.

  2. (Hypo) critical mass: do women make a difference?

    1997-01-01

    The debate about the gender impact of women journalists on society encompass several issues. First of all, there is the question of whether women have influenced and expanded the definition of "news." Surveys reveal that the topics of interest in newspapers differ for women and men, and that this gap is widening in some areas and closing in others. While some researchers find that women's reporting is more humanized, whereas that of men is more objective, feminists decry this distinction because it assumes that gender is a fixed property of individuals instead of part of a continuing process of identity-seeking. Such a rigid construction of "gender" results in relegating women to the "women's page ghetto." Secondly, there is the question of whether a "critical mass" of women in the newsroom is necessary in order for women to change patterns of gender representation. One opinion states that women will be unable to change anything as long as they remain in subordinate positions; others feel that a critical mass of 25-30% women would make a difference. It seems that long-term change will not occur until educational institutions that train journalists develop a journalistic norm that requires use of all human senses, celebrates diversity, and rejects "pre-thought" ideas. Such institutions could train the women and men who may transform the media and create a new gender code by changing existing value systems.

  3. Critical mass theory and women directors’ contribution to board strategic tasks

    Full Text Available In this article we offer an empirical test of the critical mass arguments in the discussion of women on corporate boards. The literature in the women on corporate board debate concludes that there must be at least three women on a board before the women really make a difference. These arguments are frequently used in the public debate about the understanding the impact of women on corporate boards, but they have never really been empirically tested on a large sample. In this paper we use a sample of 317 Norwegian firms. Our dependent variable is board strategic involvement. The findings support the critical mass arguments. This study offers useful insights to policy-makers interested in defining legislative measures mandating the presence of women directors in corporate boards by showing that “at least three women” may be particularly beneficial in terms of contribution to board strategic tasks.

    Critical Mass is a cycling event typically held on the last Friday of every month; its purpose is not usually formalized beyond the direct action of meeting at a set location and time and traveling as a group through city or town streets on bikes. The event originated in 1992 in San Francisco; by the end of 2003, the event was being held in over 300 cities around the world. At CERN it is held once a year in conjunction with the national Swiss campaing "Bike to work".

  5. Women and mass media: a critical and analytical study of the portrayal of Sudanese women in printed media.

    Badri, A E; Osama, S

    1995-06-01

    This study examines how Sudanese women are portrayed in the mass media. Data are obtained from a content analysis of historical records of Sudanese daily newspapers and women's magazines and from surveys among female editors in print media. The following types of newspapers are reviewed: independent newspapers; papers for the Al-Umma Party, a communist party, a Bathist party, a Muslim Nationalist Islamic Front Party, and a National Union Democratic Party; and a current military government paper. Women's magazines are published by women. Articles focus on women as the main newsmakers, women's life issues, female authors, a female focus but a male author, and famous Sudanese women. 16 content themes are identified. Women were not extensively featured or photographed in either newspapers or magazines. The Al-Umma Party paper and Al-Sudan Al-Hadith paper (an independent paper) were the only two newspapers with at least 10 photos of women. Women were pictured as professionals, educated persons, and leaders. There were 17 female editors. These editors preferred an image of women as leaders, followed by productive workers. Only 11.76% believed that women's dual roles as producers and reproducers should be portrayed. Female editors did not want a special women's page. 52.94% (the largest percentage) preferred targeting women with substantial leadership abilities. 17.65% desired the portrayal of women as workers and housewives. 58.82% did not think that the mass media image changed behavior or attitudes, because most Sudanese women are illiterate. Women's issues in both newspapers and women's magazines were devoted to women's work, achievements, and needs. The authors recommend removal of obstacles to women's equal participation in the mass media and press and research on the effect of media images on women's self-perception and behavior.

    An analysis is presented of thermal systems with minimum critical mass, based on the use of materials with optimum neutron moderating and reflecting properties. The optimum fissile material distributions in the systems are obtained by calculations with standard computer codes, extended with a routine for flat fuel importance search. It is shown that in the minimum critical mass configuration a considerable part of the fuel is positioned in the reflector region. For 239 Pu a minimum critical mass of 87 g is found, which is the lowest value reported hitherto. (author)

    Abstract Purpose: By 2006, women constituted 34% of academic medical faculty, reaching a critical mass. Theoretically, with critical mass, culture and policy supportive of gender equity should be evident. We explore whether having a critical mass of women transforms institutional culture and organizational change. Methods: Career development program participants were interviewed to elucidate their experiences in academic health centers (AHCs). Focus group discussions were held with institutional leaders to explore their perceptions about contemporary challenges related to gender and leadership. Content analysis of both data sources revealed points of convergence. Findings were interpreted using the theory of critical mass. Results: Two nested domains emerged: the individual domain included the rewards and personal satisfaction of meaningful work, personal agency, tensions between cultural expectations of family and academic roles, and women's efforts to work for gender equity. The institutional domain depicted the sociocultural environment of AHCs that shaped women's experience, both personally and professionally, lack of institutional strategies to engage women in organizational initiatives, and the influence of one leader on women's ascent to leadership. Conclusions: The predominant evidence from this research demonstrates that the institutional barriers and sociocultural environment continue to be formidable obstacles confronting women, stalling the transformational effects expected from achieving a critical mass of women faculty. We conclude that the promise of critical mass as a turning point for women should be abandoned in favor of “critical actor” leaders, both women and men, who individually and collectively have the commitment and power to create gender-equitable cultures in AHCs.

  10. Critical Routes: Women Facing Violence

    2008-11-01

    Full Text Available This paper presents the Critical Routes International Seminar – Women Facing Violence , which took place in Porto Alegre in 2008. The seminar was promoted by the Graduate Program on Collective Health at Unisinos and by the Public Health School/RS and was supported by outstanding researchers working in the fields of collective health, and social and human sciences. Initially, we discuss some conceptual aspects about gender violence, its dimensions and its consequences for the health and the life quality of the affected women. Our understanding is that violence is one of the most effective methods of controlling women in societies scarred with gender hierarchies. The structure of the seminar focused on three main discussion themes: breaking up with the violence, mechanisms for working with gender and hearing the services. These themes were chosen aiming at looking for ways to help the women and to explore efficient mechanisms to combat, reduce and, if possible, eliminate the violence perpetrated against women. At the end of the seminar, we reiterate the political commitment on the accomplishment of the public policies to face violence and the fight against all inequality, discrimination and violence forms based on gender.

    1987-01-01

    Critical masses for spent fuel are larger than for green fuel and therefore use of the increased masses could result in improved handling, storage, and transport of such materials. To apply spent fuel critical masses requires an assessment of fuel exposure and the corresponding isotopic compositions. The paper discusses several approaches at the Hanford N Reactor in establishing fuel exposure, including a direct measurement of spent to green fuel critical masses. The benefits derived from the use of spent fuel critical masses are illustrated for cask designs at the Nuclear Assurance Corporation. (author)

  14. Critical Masses for Unreflected Metal Spheres

    Westfall, Robert Michael; Wright, Richard Q.

    2009-01-01

    Calculated critical masses of bare metal spheres for 28 actinide isotopes, using the SCALE/XSDRNPM one-dimensional, discrete-ordinates system, are presented. ENDF/B-VI, ENDF/B-VII, and JENDL-3.3 cross sections were used in the calculations. Results are given for isotopes of uranium, neptunium, plutonium, americium, curium, californium, and for one isotope of einsteinium. Calculated k values for these same nuclides are also given. We show that, for non-threshold or low-threshold fission nuclides, a good approximation for the nuclide k is the value of nubar at 1 MeV. A plot of the critical mass versus k values is given for 19 nuclides with A-numbers between 232 and 250. The peaks in the critical mass curve (for seven nuclides) correspond to dips in the k curve. For the seven cases with the largest critical mass, six are even-even nuclides. Neptunium-237, with a critical mass of about 62.7 kg (ENDF/B-VI calculation), has an odd number of protons and an even number of neutrons. However, two cases with quite small critical masses, 232U and 236Pu, are also even-even. These two nuclides do not exhibit threshold fission behavior like most other even-even nuclides. The largest critical mass is 208.8 kg for 243Am and the smallest is 2.44 kg for 251Cf. The calculated k values vary from 1.5022 for 234U to 4.4767 for 251Cf. A correlation between the calculated critical mass (kg) and the fission spectrum averaged value of is given for the elements U, Np, Pu, Am, Cm, and Cf. For each of the five elements, a fit to the data for that element is provided. In each case the fit employs a negative exponential of the form mass = exp(A + B ∼ ln). The values of A and B are element dependent and vary slightly for each of the five elements. The method described here is mainly applicable for non-threshold fission nuclides (15 of the 28 nuclides considered in this paper). There are three exceptions, 238Pu, 244Cm, and 250Cf, which all exhibit threshold fission behavior.

    2000-01-01

    The review has been done to understand the resent status of the plant in facing postulated mass criticality accident. From the design concept of the plant all the components in the system including functional groups have been designed based on favorable mass/geometry safety principle. The criticality safety for each component is guaranteed because all the dimensions relevant to criticality of the components are smaller than dimensions of 'favorable mass/geometry'. The procedures covering all aspects affecting quality including the safety related are developed and adhered to at all times. Staff are indoctrinated periodically in short training session to warn the important of the safety in process of production. The plant is fully equipped with 6 (six) criticality detectors in strategic places to alert employees whenever the postulated mass criticality accident occur. In the event of Nuclear Emergency Preparedness, PT BATAN TEKNOLOGI has also proposed the organization structure how promptly to report the crisis to Nuclear Energy Control Board (BAPETEN) Indonesia.

    2017-04-01

    Full Text Available This paper investigates the influence of gender diversity in the boardroom of Croatian banks on their performance. Specifically, we deal with both management and supervisory boards. Moreover, based on critical mass theory, the authors try to find out what constitutes critical mass. Using a static panel analysis on a sample of all commercial banks that operated in the period 2002-2014, three models were estimated with return on assets (ROA, return on equity (ROE and net interest margin (NIM as dependent variables. Board structure variables include gender of the chairperson, size of the board, share of women on the board and four dummy variables constructed on critical mass theory, specifically uniform group, skewed group, tilted group and balanced group. Other controls employed in the model include capital adequacy, the growth rate of assets at the bank level, ownership, age and a crisis dummy. The main finding is that when a critical mass of 20%-40% of women on the management board has been reached, bank performance improves.

    1992-01-01

    Some of the physical assumptions underlying various nuclear mass models are discussed. The ability of different mass models to predict new masses that were not taken into account when the models were formulated and their parameters determined is analyzed. The models are also compared with respect to their ability to describe nuclear-structure properties in general. The analysis suggests future directions for mass-model development

  19. Critical mass variation of 239Pu with water dilution

    International Nuclear Information System (INIS)

    Pearlstein, S.

    1996-01-01

    The critical mass of an unreflected solid sphere of 239 Pu is ∼ 10 kg. The increase in critical mass observed for small water dilutions of unreflected 239 Pu spheres is paradoxical. Introducing small amounts of water uniformly throughout the sphere increases the spherical volume containing the same amount of 239 Pu as the critical solid sphere. The increase in radius decreases the surface-to-volume ratio of the sphere, which has the effect to first order of decreasing the neutron leakage, which is proportional to the surface, relative to the fissions, which are proportional to the volume. The reduction in neutron leakage is expected to reduce the critical mass, but instead, the critical mass is observed to increase. It is discussed how changes in the fast neutron spectrum with corresponding changes in the nuclear parameters result in an increase in critical mass for small water dilutions

  1. Relationship between keff and the fraction of critical mass

    O'Dell, R.D.; Parsons, D.K.

    1997-01-01

    It is not universally understood that k eff and fractional critical mass are related in a non linear fashion. For example, a neutronic system with a k eff = 0. 95 is NOT at 95% of its critical mass. What is striking is just how non-linear the relationship between k eff and critical mass really is. This relationship is investigated and documented below for both unfavorable (i.e., very reactive) and favorable (less reactive) geometries. The implications of this non-linearity for criticality safety regulation will also be discussed

  2. Calculation of the minimum critical mass of fissile nuclides

    International Nuclear Information System (INIS)

    Wright, R.Q.; Hopper, Calvin Mitchell

    2008-01-01

    The OB-1 method for the calculation of the minimum critical mass of fissile actinides in metal/water systems was described in a previous paper. A fit to the calculated minimum critical mass data using the extended criticality parameter is the basis of the revised method. The solution density (grams/liter) for the minimum critical mass is also obtained by a fit to calculated values. Input to the calculation consists of the Maxwellian averaged fission and absorption cross sections and the thermal values of nubar. The revised method gives more accurate values than the original method does for both the minimum critical mass and the solution densities. The OB-1 method has been extended to calculate the uncertainties in the minimum critical mass for 12 different fissile nuclides. The uncertainties for the fission and capture cross sections and the estimated nubar uncertainties are used to determine the uncertainties in the minimum critical mass, either in percent or grams. Results have been obtained for U-233, U-235, Pu-236, Pu-239, Pu-241, Am-242m, Cm-243, Cm-245, Cf-249, Cf-251, Cf-253, and Es-254. Eight of these 12 nuclides are included in the ANS-8.15 standard.

    Full Text Available ABSTRACT The objective of this paper is to analyze critical situations experienced by women entrepreneurs and understand how they have overcome such situations. The study contributes to the understanding of the issues related to the activities of women entrepreneurs and shows that the use of the critical incident technique is relevant to the development of research in the field of entrepreneurship. The data were collected using a specific form with 115 women participating in the study. The analysis of critical incidents showed that in addition to the practical issues regarding the management of their business, emotions are interconnected with their business development. Unlike international studies in the field, the critical incidents experienced by Brazilian women entrepreneurs overlap with personal aspects. The women involved in this study face emotional difficulties, but are also motivated by strong feelings of determination to overcome their problems.

    With more than 200 malfunctions recorded in the early 1990's the outmoded nuclear reactors in the former Soviet Union are in critical condition. Unfortunatly, there may not be enough money to monitor them, much less update them, says Artiom Ustinov, an expert in the Russian Ministry of Foreign Affairs in Moscow. In on short decade, Russia's nuclear research budget has been slashed from $1.5 billion to $250 million. That amount of money simply cannot be stretched far enough to address safety issues, Ustinov says. open-quotes Currently, nuclear reactors in the former Soviet Union pose a greater environmental threat than ever before,close quotes ustinov says. open-quotes In fact, almost half the nuclear power plants operating in Russia today are Chernobyl-like.close quotes and most of these facilities are located in such large industrial centers as Moscow and st.

    As part of a standards effort of the American Nuclear Society to establish subcritical mass limits for the transuranium actinides, critical masses were calculated for seven actinides, critical masses were calculated for seven actinide elements in bare, water-reflected, and steel-reflected metal systems. For the nuclides /sup 242/Pu and /sup 241/Am, values obtained with ENDF/B-V cross-section data were in much better agreement with values inferred from experimental measurement than were initial values calculated with ENDF/B-IV data. A brief description of the analytical methods employed is followed by a presentation of the results. 10 refs

    Shi, Dong-Mei; Wang, Bing-Hong

    2017-07-01

    In this study, the enhancing parameter represented the value of the public goods to the public in public goods game, and was rescaled to a Fermi-Dirac distribution function of critical mass. Public goods were divided into two categories, consumable and reusable public goods, and their coevolution with cooperative behavior was studied. We observed that for both types of public goods, cooperation was promoted as the enhancing parameter increased when the value of critical mass was not very large. An optimal value of critical mass which led to the best cooperation was identified. We also found that cooperations emerged earlier for reusable public goods, and defections became extinct earlier for the consumable public goods. Moreover, we observed that a moderate depreciation rate for public goods resulted in an optimal cooperation, and this range became wider as the enhancing parameter increased. The noise influence on cooperation was studied, and it was shown that cooperation density varied non-monotonically as noise amplitude increased for reusable public goods, whereas decreased monotonically for consumable public goods. Furthermore, existence of the optimal critical mass was also identified in other three regular networks. Finally, simulation results were utilized to analyze the provision of public goods in detail.

  13. Fission, critical mass and safety-a historical review

    International Nuclear Information System (INIS)

    Meggitt, Geoff

    2006-01-01

    Since the discovery of fission, the notion of a chain reaction in a critical mass releasing massive amounts of energy has haunted physicists. The possibility of a bomb or a reactor prompted much of the early work on determining a critical mass, but the need to avoid an accidental critical excursion during processing or transport of fissile material drove much that took place subsequently. Because of the variety of possible situations that might arise, it took some time to develop adequate theoretical tools for criticality safety and the early assessments were based on direct experiment. Some extension of these experiments to closely similar situations proved possible, but it was not until the 1960s that theoretical methods (and computers to run them) developed enough for them to become reliable assessment tools. Validating such theoretical methods remained a concern, but by the end of the century they formed the backbone of criticality safety assessment. This paper traces the evolution of these methods, principally in the UK and USA, and summarises some related work concerned with the nature of criticality accidents and their radiological consequences. It also indicates how the results have been communicated and used in ensuring nuclear safety. (review)

    2000-01-01

    To Analyze the transvaginal ultrasonographic(TVUS)findings of the cystic adnexal masses in postmenopausal women for differentiation of benign and malignant masses. We retrospectively reviewed the TVUS images of surgically proven 142 cystic adnexal masses in 125 patients. The masses were classified according to the pathologic findings. The size, the internal echogenicity, the internal septation, the external wall of the masses on US were analyzed and scored using Multicenter scoring system. Serum CA-125 concentration was also recorded. At surgery of 142 masses, 125 benign (88%), and 17 borderline/malignant masses (12%) were found. Among 125 benign masses, 88 masses were larger than 5 cm, 125 had smooth external wall, 109 had absence or thin internal septation, and 107 had anechoic or homogenous low internal echogenicity. Of the 17 borderline/malignant masses, there were 17 masses larger than 5 cm, 2 with smooth external wall, 12 without or with thin internal septation, and 7 with anechoic or homogenous low internal echogenicity. Multicenter score was below 8 in all benign masses, and in 4 borderline/malignant masses. Serum CA-125 concentration with normal range was in 90 patients with benign masses, and in 2 patients with borderline/malignant masses. Cystic adnexal masses with smooth external wall and internal septation, internal echogenic portion less than 10%, score below 8 on TVUS would be diagnosed as benign masses in postmenopausal women with normal serum CA-125 concentration.

    The fissile material storage tanks in the Hanford Plutonium Critical Mass Laboratory (CML) in Richland, Washington, are presently being upgraded. During the design and planning phase of this modification, criticality analysis was necessary to compare potential moderator/absorber materials used as isolators between tanks. A parameter study was performed to assist in determining the appropriate moderator material to be used in the plutonium nitrate storage tank system in the mix room at the CML. Four moderator/absorber materials were identified as providing adequate isolation between the tanks

    A total of 386 critical flow data points from 19 runs of 27 runs in the Marviken Test were selected and compared with the predictions by the correlations based on the critical flow scaling parameters. The results show that the critical mass flux in the very large diameter pipe can be also characterized by two scaling parameters such as discharge coefficient and dimensionless subcooling (C{sub d,ref} and {Delta}{Tau}{sup *} {sub sub}). The agreement between the measured data and the predictions are excellent. 8 refs., 8 figs. 1 tab. (Author)

    2011-11-01

    As a result of recent events, including natural disasters and pandemics, mass critical care planning has become a priority. In general, planning involves limiting the scope of disasters, increasing the supply of medical resources, and allocating scarce resources. Entities at varying levels have articulated ethical frameworks to inform policy development. In spite of this increased focus, children have received limited attention. Children require special attention because of their unique vulnerabilities and needs. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subgroups by topic area and performed literature reviews of MEDLINE and Ovid databases. Draft documents were subsequently developed and revised based on the feedback from the Task Force. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. This document reflects expert input from the Task Force in addition to the most current medical literature. The Ethics Subcommittee recommends that surge planning seek to provide resources for children in proportion to their percentage of the population or preferably, if data are available, the percentage of those affected by the disaster. Generally, scarce resources should be allocated on the basis of need, benefit, and the conservation of resources. Estimates of need, benefit, and resource utilization may be more subjective or objective. While the

    More than 200 actinide isotopes are known; most of them have very short half-lives (only 45 with T 1/2 > 40 days). Only 41 have been predicted capable of a self-sustaining nuclear chain reaction, some of them with fast neutrons and others with either thermal or fast neutrons. Of these 41 there are 13 nuclides for which the average production is >1 g/tonne for pressurized water reactors or boiling water reactors (35 GWd/tonne--power 35 W/g; cooling time, 90 days). Six actinides, 233 U, 235 U, 238 U, 239 Pu, 240 Pu, and 241 Pu, have cross sections that are relatively well known. Cross sections for the other actinides are not as well known. In the United States, criticality safety guidelines for nuclides other than 233 U, 235 U, and 239 Pu is provided by the American National Standard for Nuclear Criticality Control of Special Actinide Elements, ANSI/ANS-8.15. The standard appeared in 1981 and was reaffirmed in 1987 and 1995. The standard provides guidance for 14 nuclei: 237 Np, 238 Pu, 240 Pu, 241 Pu, 242 Pu, 241 Am, 242m Am, 243 Am, 243 Cm, 244 Cm, 245 Cm, 247 Cm, 249 Cf, and 251 Cf. The ANS-8.15 Standard Work Group is in the process of revising the standard. Five nuclides will be added to the list of nuclides included-- 231 Pa, 234 U, 250 Cf, 252 Cf, and 254 Es--resulting in a total of 19 nuclides in the revised standard. Subcritical mass limits in the current standard are based on calculations by Clark and Westfall. The calculations were based on ENDF/B-IV and preliminary ENDF/B-V evaluations. For several of the actinides, new or revised evaluations are available in ENDF/B-VI. All of the 19 nuclides in the revised standard are included in the current paper with the exception of 231 Pa. In a previous paper, minimum critical mass estimates for metal-water mixtures (spherical geometry), fully reflected by water, for 20 fissile nuclides with values of Z between 92 and 99 were given. A simple exponential fit was developed that gives quite accurate values for the

    Full Text Available Women’s participation in Cervantine criticism at the beginning of the twentieth century (1905-1906 has barely received recognition. This paper analyses the different perspectives women authors used to approach both Cervantes and his work. Strict literary criticism coexists with the exploration of Don Quixote’s main characters in the philosophical and literary essays of María Lejárraga, Matilde Ras, Concha Espina and Carmen de Burgos. The authors studied include intheirs texts their social concerns and feminist ideology and give their opinion about key political and intellectual debates affecting society at the beginning of the twentieth century.

    2018-01-01

    We compared accuracy of body mass index (BMI) versus lean mass index (LMI) to predict sarcopenia in 58 community-dwelling women (74.1±0.9 years). Lean mass was measured with multi-frequency bioelectrical impedance analysis, and strength was measured with Arm Curl test, Chair Stand test, and handgrip dynamometry. Sarcopenia was defined as low LMI. When categorized by BMI, normal women had less absolute lean mass (37.6±1.0 vs. 42.6±0.9 kg; Plean mass (14.1±0.2 vs. 16.1±0.2 kg/m2; Plean mass (44.0±0.7 vs. 35.7±0.7 kg; Plean mass (16.2±0.2 vs. 13.8±0.2 kg/m2; Plean mass and strength. For clinical assessment, calculation of LMI rather than BMI is appropriate.

  3. Plutonium Critical Mass Curve Comparison to Mass at Upper Subcritical Limit (USL) Using Whisper

    International Nuclear Information System (INIS)

    Alwin, Jennifer Louise; Zhang, Ning

    2016-01-01

    Whisper is computational software designed to assist the nuclear criticality safety analyst with validation studies with the MCNP ® Monte Carlo radiation transport package. Standard approaches to validation rely on the selection of benchmarks based upon expert judgment. Whisper uses sensitivity/uncertainty (S/U) methods to select relevant benchmarks to a particular application or set of applications being analyzed. Using these benchmarks, Whisper computes a calculational margin. Whisper attempts to quantify the margin of subcriticality (MOS) from errors in software and uncertainties in nuclear data. The combination of the Whisper-derived calculational margin and MOS comprise the baseline upper subcritical limit (USL), to which an additional margin may be applied by the nuclear criticality safety analyst as appropriate to ensure subcriticality. A series of critical mass curves for plutonium, similar to those found in Figure 31 of LA-10860-MS, have been generated using MCNP6.1.1 and the iterative parameter study software, WORM S olver. The baseline USL for each of the data points of the curves was then computed using Whisper 1.1. The USL was then used to determine the equivalent mass for plutonium metal-water system. ANSI/ANS-8.1 states that it is acceptable to use handbook data, such as the data directly from the LA-10860-MS, as it is already considered validated (Section 4.3 4) ''Use of subcritical limit data provided in ANSI/ANS standards or accepted reference publications does not require further validation.''). This paper attempts to take a novel approach to visualize traditional critical mass curves and allows comparison with the amount of mass for which the k eff is equal to the USL (calculational margin + margin of subcriticality). However, the intent is to plot the critical mass data along with USL, not to suggest that already accepted handbook data should have new and more rigorous requirements for validation.

    Quantify the muscle mass and body weight variation in critically ill patients and to identify associated factors. A descriptive follow-up study. Data for demographic variables, body weight, fluid balance, daily kilocalories, the amount of sedation and muscle relaxants received and motor physiotherapy applied were collected. Three consecutive measurements were performed in the brachial biceps and quadriceps rectus by using ultrasound, upon admission and every 5 days until discharge. 68 patients were included. Average age was of 73.5 [57-78,5] years. The median length of stay was 9.5 [5.5 -15] days. The median 16 (SD=5.7) daily kilocalories per kg/weight, 91.2% received sedation, 44.1% received muscle relaxants and 20% received physiotherapy. The patients presented a muscle wasting of 4.9 (SD=3.9)mm, p <.001 in the brachial biceps and 5.6 (SD=4.8)mm, p <.001 in the quadriceps rectus. Regression analysis selected the length of stay and the muscle relaxants are the most influential variables in the brachial biceps muscle wasting (R2=0.4), and length of stay as the most influential in the quadriceps rectus muscle wasting (R2=0.3). Patient's mean body weight on admission was of 81.1 (SD=15)kg and 81.2 (SD=14.2)kg on discharge, p=.95. The critically ill patient presents a significant muscle waste related with the length of stay and the treatment received with muscle relaxants. Patients are being discharged with a similar body weight to which they were admitted but with a significant reduction of muscle mass. Copyright © 2014 Elsevier España, S.L.U. y SEEIUC.

    Excess weight in women with fibromyalgia syndrome (FMS) may further contribute to joint pain and fatigue. However, there is little research addressing weight issues in this population. This study examined the relationship of body mass index (BMI) to quality of life. Quality of life was measured by the 36-Item Short Form Health Survey, severity of FMS, nutritional intake, Barriers to Health Promoting Behaviors for Disabled Persons Scale (BS), and self-efficacy for health-promoting behaviors (Self-Rated Abilities for Health Practices Scale) in women with FMS. Baseline data were collected on 179 women diagnosed with FMS. Controlling for age, BMI was significantly (p < .05) correlated with 36-Item Short Form Health Survey subscales of physical functioning, bodily pain and vitality, severity of FMS using the Tender Point Index, calories, protein, fat, saturated fat, BS, and Self-Rated Abilities for Health Practices Scale subscale for exercise. The findings support a growing body of evidence that excess weight is negatively related to quality of life and pain in women with FMS.

    An association between anorexia nerviosa (AN) and low bone mass has been demonstrated. Bone loss associated with AN involves hormonal and nutritional impairments, though their exact contribution is not clearly established. We compared bone mass in AN patients with women of similar weight with no criteria for AN, and a third group of healthy, normal-weight, age-matched women. The study included forty-eight patients with AN, twenty-two healthy eumenorrhoeic women with low weight (LW group; BMI 18.5 kg/m2 (control group), all of similar age. We measured lean body mass, percentage fat mass, total bone mineral content (BMC) and bone mineral density in lumbar spine (BMD LS) and in total (tBMD). We measured anthropometric parameters, leptin and growth hormone. The control group had greater tBMD and BMD LS than the other groups, with no differences between the AN and LW groups. No differences were found in tBMD, BMD LS and total BMC between the restrictive (n 25) and binge-purge type (n 23) in AN patients. In AN, minimum weight (P = 0.002) and percentage fat mass (P = 0.02) explained BMD LS variation (r2 0.48) and minimum weight (r2 0.42; P = 0.002) for tBMD in stepwise regression analyses. In the LW group, BMI explained BMD LS (r2 0.72; P = 0.01) and tBMD (r2 0.57; P = 0.04). We concluded that patients with AN had similar BMD to healthy thin women. Anthropometric parameters could contribute more significantly than oestrogen deficiency in the achievement of peak bone mass in AN patients.

  10. Steamworlds: Atmospheric Structure and Critical Mass of Planets Accreting Icy Pebbles

    Chambers, John

    2017-01-01

    In the core accretion model, gas-giant planets first form a solid core, which then accretes gas from a protoplanetary disk when the core exceeds a critical mass. Here, we model the atmosphere of a core that grows by accreting ice-rich pebbles. The ice fraction of pebbles evaporates in warm regions of the atmosphere, saturating it with water vapor. Excess water precipitates to lower altitudes. Beneath an outer radiative region, the atmosphere is convective, following a moist adiabat in saturated regions due to water condensation and precipitation. Atmospheric mass, density, and temperature increase with core mass. For nominal model parameters, planets with core masses (ice + rock) between 0.08 and 0.16 Earth masses have surface temperatures between 273 and 647 K and form an ocean. In more massive planets, water exists as a supercritical convecting fluid mixed with gas from the disk. Typically, the core mass reaches a maximum (the critical mass) as a function of the total mass when the core is 2–5 Earth masses. The critical mass depends in a complicated way on pebble size, mass flux, and dust opacity due to the occasional appearance of multiple core-mass maxima. The core mass for an atmosphere of 50% hydrogen and helium may be a more robust indicator of the onset of gas accretion. This mass is typically 1–3 Earth masses for pebbles that are 50% ice by mass, increasing with opacity and pebble flux and decreasing with pebble ice/rock ratio.

    2003-04-01

    Within the next 30 years there will be equal numbers of women and men in the medical workforce. Indications are that women are increasing their participation in specialties other than general practice, although at a slower rate than their participation in the workforce as a whole. To inform those involved in training and employment of medical women, this study investigated the influencing factors in career decision making for female medical graduates. A total of 305 women medical graduates from the University of Auckland responded to a mail survey (73% response rate) which examined influences on decision making, in both qualitative and quantitative ways, as part of a larger survey. Most women were satisfied with their careers. The principal component analysis of the influencing factors identified four distinct factors important in career choice - interest, flexibility, women friendliness and job security, although the first two of these were rated more highly than the others. Barriers to full participation by medical women in training and employment need to be systematically examined and removed. This is not only to allow women themselves to reach their full potential, but for workforce and socio-economic reasons. Initiatives that allow and value more flexible training and work practices, particularly through the years of child raising, are necessary for women and the health care workforce at large.

    In a severe accident, the reactor vessel is heated by the decay heat from core melts and the outer surface of reactor vessel is cooled by the natural convection of water pool. When the heat flux increases, boiling will start. Further increase of the heat flux may result in the CHF, which is generated by the bubble combinations. The CHF means that the reactor vessel was separated with coolant and wall temperature is raised rapidly. It may damage the reactor vessel. Also the CHF indicates the maximum cooling capability of the system. Therefore, the CHF has been used as a criterion for the regulatory and licensing. Mechanism of hydrogen vapor bubbles generated and combined can be simulated water bubbles mechanism. And also the both heat and mass transfer mechanism of CHF can be identified in the same methods. Therefore, the CHF phenomena can be simulated enough by mass transfer.

    The energy of the kaonic 6h → 5g transition has been determined using the calculated μ/rho curve. Because the detectors used could not resolve the noncircular transitions, the predictions from a calculated cascade program were used. According to the cascade results for potassium, the number of noncircular x-rays was about 10% of all the transitions between n = 6 to n = 5. Based on the available information, the mass of the kaon was measured to be 493.576/sub -0.069//sup +0.044/ MeV

    A homogeneous U-233 uranyl nitrate solution fuelled BeO reflected, low critical mass reactor has been built at the Bhabha Atomic Research Centre, India. Christened PURNIMA II, the reactor was used for the study of the variation of critical mass as a function of fuel solution concentration to determine the minimum critical mass achievable for this geometry. Other experiments performed include the determination of temperature coefficient of reactivity, study of time behaviour of photoneutrons produced due to interaction between decaying U-233 fission product gammas and the beryllium reflector and reactor noise measurements. Besides being the only operational U-233 fuelled reactor at present, PURNIMA II also has the distinction of having attained the lowest critical mass of 397 g of fissile fuel for any operating reactor at the current time. The paper briefly describes the facility and gives an account of the experiments performed and results achieved. (author)

Total body, lumbar spine, total femur, and femoral neck BMD and body composition were measured by dual x-ray absorptiometry. To evaluate the associations between fat mass and lean mass and various measures of BMD, multivariable linear regression models were used to estimate the regression coefficients for fat mass and lean mass, first in separate equations and then with both fat mass and lean mass in the same equation.Results: Among the study population, 1448 subjects (91.7% were postmenopausal and 131 (8.3% were perimenopausal. In postmenopausal women, after controlling for age, height, and duration of menopause, both fat mass and lean mass were positively correlated with BMD when they were analyzed independently of each other. When included in the same equation, both fat mass and lean mass continued to show a positive effect, but lean mass had a significantly greater impact on BMD than fat mass at all regions except for total body. Lean mass but not fat mass had a positive effect on BMD at all skeletal sites except the lumbar spine, after controlling for age and height in perimenopausal

    Criticality mass calculations are reported for 241 Am, 242m Am and 243 Am using the MONK and MCNP computer codes with the UKNDL, JEF-2.2, ENDF/B-VI and JENDL-3.2 nuclear data libraries. Results are reported for spheres of americium metal and dioxide in bare, water reflected and steel reflected systems. Comparison of results led to the identification of a serious inconsistency in the 241 Am ENDF/B-VI DICE library used by MONK - this demonstrates the importance of using different codes to verify critical mass calculations. The 241 Am critical mass estimates obtained using UKNDL and ENDF/B-VI show good agreement with experimentally inferred data, whilst both JEF-2.2 and JENDL-3.2 produce higher estimates of critical mass. The computed critical mass estimates for 242m Am obtained using ENDF/B-VI are lower than the results produced using the other nuclear data libraries - the ENDF/B-VI fission cross-section for 242m Am is significantly higher than the other evaluations in the fast region and is not supported by recent experimental data. There is wide variation in the computed 243 Am critical mass estimates suggesting that there is still considerable uncertainty in the 243 Am nuclear data. (author)

    As part of the research into nuclear measurement techniques, a series of measurements was performed that have applications to criticality safety and nuclear material handling. The critical mass of a set of bare, enriched-uranium metal hemispherical shells, known as the Rocky Flats shells, was measured for an assembly having an inside radius of 2.347 cm. The critical mass value was extrapolated from a series of subcritical measurements using three different kinds of sources (AmBe, AmF, and 252 Cf) placed at the center of the shells. Two kinds of neutron detection configurations (a 1% efficiency and a 25% efficiency configuration) were used to make the measurements

    We study radial solutions in a ball of R N of a semilinear, parabolic–elliptic Patlak–Keller–Segel system with a nonlinear sensitivity involving a critical power. For N = 2, the latter reduces to the classical ‘linear’ model, well known for its critical mass 8π. We show that a critical mass phenomenon also occurs for N ⩾ 3, but with a strongly different qualitative behaviour. More precisely, if the total mass of cells is smaller or equal to the critical mass M-bar , then the cell density converges to a regular steady state that is supported strictly inside the ball as time goes to infinity. In the case of the critical mass, this result is nontrivial since there exists a continuum of stationary solutions and is moreover in sharp contrast with the case N = 2 where infinite-time blow-up occurs. If the total mass of cells is larger than M-bar , then all radial solutions blow up in finite time. This actually follows from the existence (unlike for N = 2) of a family of self-similar, blowing-up solutions that are supported strictly inside the ball. (paper)

  9. Women's nutrition -- convergence of programmes -- a critical issue.

    Many factors are responsible for malnutrition among women. Malnutrition is mainly caused by inadequate energy intake and nutritional anemia. Social factors affecting the energy balance include inappropriate intra family distribution, inadequate food intake during pregnancy, conception when younger than 18 years old, and continued high physical activity during pregnancy. Discrimination against girls in the form of insufficient food intake affects girls throughout their lives and contributes to poor adolescent growth and poor maternal stature (height and weight). Poor maternal stature has been linked with adverse effects on pregnancy outcomes: low birth weight infants and infant mortality. About 66% of infants were found to be of low birth weight among mothers weighing less than 40 kg and with a pregnancy weight gain of less than 5 kg. The recommended weight gain during pregnancy is 10-12 kg. Maternal weight has been found to be closely linked with negative effects on fetal growth and birth weight. Nutrition programs must contend with a variety of social, economic, health, and legislative approaches for improving women's status. Food supplementation during pregnancy and adolescence are as important as raising the marriage and conception age. Energy deficits of iron, vitamin A, and iodine need to be fulfilled. Energy saving devices would help to reduce the physical demands on women during pregnancy. Nutrition education for promoting adequate nutritional and energy intake and prevention of nutrient deficiencies needs to be implemented. Health workers have been known for inadequate attention to nutrition. The opportunity for nutritional supplementation and education is available during women's contacts with immunization interventions. A complex prescription applied continuously and in harmony with other health efforts will assure maternal nutritional support.

  10. Social Criticism on Works of Contemporary Women Story Writers

    Full Text Available Goldmann's genetic structuralism approach is one of the literary critique approaches and believes that the literary text are derived from the ideology governing the classes of society, and focuses on study of stories and their structures to know the social structures. A review of the changes made in the themes and subjects of the works of the Iranian story writers that most of them are from the middle class of society, indicates the growth of awareness and understanding of Iranian women about their identity and individuality and the achievement of conditions beyond what they are. Although in popular stories, most Iranian female storytellers are still interested in the reproduction of traditional gender stereotypes, but female storywriters in the field of transcendental literature have entered the changes made in their cognitive realm to the actions of characters of their stories. This reveals that they seek to understand their own self and place in the world around them. Love and loneliness resulted by the confrontation between men and women are a common theme in these works that have been narrated on the various issues arising from the family and social relationships of women.

    When evaluating systems in criticality safety, it is important to approximate the answer before any analysis is performed. There is currently interest in establishing the minimum critical parameters for fissile actinides. The purpose is to describe the OB-1 method for estimating the minimum critical mass for thermal systems based on one-group calculations and 235 U spheres fully reflected by water. The observation is made that for water-moderated, well-thermalized systems, the transport and leakage from the system are dominated by water. Under these conditions two fissile mixtures will have nearly the same critical volume provided the infinite media multiplication factor (k ∞ ) for the two systems is the same. This observation allows for very simple estimates of critical concentration and mass as a function of the hydrogen-to-fissile (H/X) moderation ratio by comparison to the known 235 U system

    Critical consciousness, the awareness of social oppression, is important to investigate as a buffer against HIV disease progression in HIV-infected African American women in the context of experiences with discrimination. Critical consciousness comprises several dimensions, including social group identification, discontent with distribution of social power, rejection of social system legitimacy, and a collective action orientation. The current study investigated self-reported critical consciousness as a moderator of perceived gender and racial discrimination on HIV viral load and CD4+ cell count in 67 African American HIV-infected women. Higher critical consciousness was found to be related to higher likelihood of having CD4+ counts over 350 and lower likelihood of detectable viral load when perceived racial discrimination was high, as revealed by multiple logistic regressions that controlled for highly active antiretroviral therapy (HAART) adherence. Multiple linear regressions showed that at higher levels of perceived gender and racial discrimination, women endorsing high critical consciousness had a larger positive difference between nadir CD4+ (lowest pre-HAART) and current CD4+ count than women endorsing low critical consciousness. These findings suggest that raising awareness of social oppression to promote joining with others to enact social change may be an important intervention strategy to improve HIV outcomes in African American HIV-infected women who report experiencing high levels of gender and racial discrimination.

    2008-01-01

    We conducted in-depth interviews with 37 incarcerated women on their experience of rage towards their intimate partner. Participants used specific criteria to distinguish their experience of rage from anger. Rage is described as an overwhelming experience with particular physiological and cognitive changes that takes control of a woman's emotions and actions. In contrast, anger is described as a controllable emotion with a specific termination point. Motivations for acting violently in rage with an intimate partner are described and discussed. Findings suggest a primary trigger for experiencing rage is feeling threatened and feeling emotionally overwhelmed.

    Improved health outcomes are associated with neonatal and pediatric critical care in well-organized, cohesive, regionalized systems that are prepared to support and rehabilitate critically ill victims of a mass casualty event. However, present systems lack adequate surge capacity for neonatal and pediatric mass critical care. In this document, we outline the present reality and suggest alternative approaches. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subcommittees by topic area and performed literature reviews of MEDLINE and Ovid databases. The Steering Committee produced draft outlines through consensus-based study of the literature and convened October 6-7, 2009, in New York, NY, to review and revise each outline. Eight draft documents were subsequently developed from the revised outlines as well as through searches of MEDLINE updated through March 2010.The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. Feedback on each manuscript was compiled and the Steering Committee revised each document to reflect expert input in addition to the most current medical literature. States and regions (facilitated by federal partners) should review current emergency operations and devise appropriate plans to address the population-based needs of infants and children in large-scale disasters. Action at the state, regional, and federal levels should address

    The authors present a conceptual framework for expanding the use of relational theory with African-American women. Relational theory (RT) informs practice with women but is inadequate in addressing all aspects of culture and identity. RT presumes that all women desire or are able to make therapeutic connections, yet race, gender, and cultural experiences influence their ability to do so. Successful practice with minority women must address racism and its impact. Critical race theory (CRT) that incorporates a solution-focused (SF) approach is well-suited to address the limits of RT. This overview of a CRT/SF approach describes treatment for diverse women that extends RT and enhances effective social work practice to provide culturally sensitive treatment to women.

    Current subcritical limits for a number of uranium and plutonium materials (metals and compounds) as given in the ANSI/ANS standards for criticality safety are based on evaluations performed in the late 1970s and early 1980s. This paper presents the results of an analytical study of the minimum critical mass values for a set of materials using current codes and standard cross section sets. This work is meant to produce a consistent set of minimum critical mass values that can form the basis for adding new materials to the single-parameter tables in ANSI/ANS-8.1. Minimum critical mass results are presented for bare and water reflected full-density spheres and for full density moist (1.5 wt-% water) as calculated with KENO-Va, MCNP4A and ONEDANT. Calculations were also performed for both dry and moist materials at one-half density. Some KENO calculations were repeated using several cross section sets to examine potential bias differences. The results of the calculations were compared to the currently accepted subcritical limits. The calculated minimum critical mass values are reasonably consistent for the three codes, and differences most likely reflect differences in the cross section sets. The results are also consistent with values given in ANSI/ANS-8.1. 3 refs., 2 tabs

    By observing the results in Fig. 4 and Fig. 5 we can see that virtual mass effects are important in predicting critical flow. However, as seen in Fig. 7a, in which all three flows are predicted to be critical (Δ=0), it is difficult to distinguish one set of conditions from the other by just considering the pressure profile. Clearly more detailed data, such as the throat void fraction, is needed for discrimination between these calculations. Moreover, since the calculated critical flows have been found to be sensitive to initial mass flux, and void fraction, careful measurements of those parameters are needed before accurate virtual mass parameters can be determined from these data. It can be concluded that the existing Moby Dick data is inadequate to allow one to deduce accurate values of the virtual mass parameters C/sub VM/ and λ. Nevertheless, more careful experiments of this type are uniquely suited for the determination of these important parameters. It appears that the use of a nine equation model, such as that discussed herein, coupled with more detailed accurate critical flow data is an effective means of determining the parameters in interfacial momentum transfer models, such as virtual mass effects, which are only important during strong spatial accelerations. Indeed, there are few other methods available which can be used for such determinations

    Full Text Available One of the most exciting and unexpected objects in the 2014 Tate Britain exhibition Kenneth Clark: Looking for Civilization was a prototype plate by Vanessa Bell and Duncan Grant for a dinner service commissioned by Clark in 1932. The completed set of 50 plates, which feature portraits of “famous women” throughout history, survived wartime bombing and several moves of house by the Clark family, but for the past 30 years its whereabouts had been unknown to art historians. In spring 2017, prompted by the Vanessa Bell monographic exhibition at Dulwich Picture Gallery, the owner of the dinner service contacted Piano Nobile art gallery. It soon emerged that not only was the set intact, but that the plates themselves, hand-painted on Wedgwood blanks, have been preserved in their original condition. This Look First feature offers the first opportunity for close scholarly examination of a culturally and visually potent art object. The feature uses photography, archival materials, and film to explore the process of creating the set and its place in the history of art. The present article includes a catalogue with biographical entries for each of the women featured in the set, together with source images and preparatory materials. The article text establishes where this playful, yet ground-breaking work fits within the artists’ oeuvres, and within a feminist history of art. Further materials expanding the feature’s reach, including a filmed discussion with the artist Judy Chicago, will be released in early 2018.

  4. Representations of women and drug use in policy: A critical policy analysis.

    2018-06-01

    Contemporary research in the drugs field has demonstrated a number of gender differences in patterns and experiences of substance use, and the design and provision of gender-responsive interventions has been identified as an important policy issue. Consequently, whether and how domestic drug policies attend to women and gender issues is an important question for investigation. This article presents a policy audit and critical analysis of Australian national and state and territory policy documents. It identifies and discusses two key styles of problematisation of women's drug use in policy: 1) drug use and its effect on women's reproductive role (including a focus on pregnant women and women who are mothers), and 2) drug use and its relationship to women's vulnerability to harm (including violent and sexual victimisation, trauma, and mental health issues). Whilst these are important areas for policy to address, we argue that such representations of women who use drugs tend to reinforce particular understandings of women and drug use, while at the same time contributing to areas of 'policy silence' or neglect. In particular, the policy documents analysed are largely silent about the harm reduction needs of all women, as well as the needs of women who are not mothers, young women, older women, transwomen or other women deemed to be outside of dominant normative reproductive discourse. This analysis is important because understanding how women's drug use is problematised and identifying areas of policy silence provides a foundation for redressing gaps in policy, and for assessing the likely effectiveness of current and future policy approaches.

    Maintenance of lean muscle mass and related strength is associated with lower risk for numerous chronic diseases of aging in women. Our aim was to evaluate whether the association between dietary protein and lean mass differs by physical activity level, amino acid composition, and body mass index categories. We performed a cross-sectional analysis of a prospective cohort. Participants were postmenopausal women from the Women's Health Initiative with body composition measurements by dual-energy x-ray absorptiometry (n=8,298). Our study measured percent lean mass, percent fat mass, and lean body mass index. Linear regression models adjusted for scanner serial number, age, calibrated energy intake, race/ethnicity, neighborhood socioeconomic status, and recreational physical activity were used to determine the relationship between protein intake and body composition measures. Likelihood ratio tests and stratified analysis were used to investigate physical activity and body mass index as potential effect modifiers. Biomarker-calibrated protein intake was positively associated with percent lean mass; women in the highest protein quintile had 6.3 percentage points higher lean mass than the lowest quintile (Plean body mass index were both inversely related to protein intake (both Plean body mass index (P interaction =0.011). Leucine intake was associated with lean mass, as were branched chain amino acids combined (both Plean mass in postmenopausal women. Importantly, those that also engage in physical activity have the highest lean mass across body mass index categories. Copyright © 2017 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    It has at times been indicated that Landau introduced neutron stars in his classic paper of 1932. This is clearly impossible because the discovery of the neutron by Chadwick was submitted more than one month after Landau's work. Therefore, and according to his calculations, what Landau really did was to study white dwarfs, and the critical mass he obtained clearly matched the value derived by Stoner and later by Chandrasekhar. The birth of the concept of a neutron star is still today unclear. Clearly, in 1934, the work of Baade and Zwicky pointed to neutron stars as originating from supernovae. Oppenheimer in 1939 is also well known to have introduced general relativity (GR) in the study of neutron stars. The aim of this note is to point out that the crucial idea for treating the neutron star has been advanced in Newtonian theory by Gamow. However, this pioneering work was plagued by mistakes. The critical mass he should have obtained was 6.9 M, not the one he declared, namely, 1.5 M. Probably, he was taken to this result by the work of Landau on white dwarfs. We revise Gamow's calculation of the critical mass regarding calculational and conceptual aspects and discuss whether it is justified to consider it the first neutron-star critical mass. We compare Gamow's approach to other early and modern approaches to the problem.

    The interpretation of gravitational microlensing events caused by planetary systems or multiple stars is based on the n-point-mass lens model. The first planets detected by microlensing were well described by the two-point-mass model of a star with one planet. By the end of 2014, four events involving three-point-mass lenses had been announced. Two of the lenses were stars with two planetary companions each; two were binary stars with a planet orbiting one component. While the two-point-mass model is well understood, the same cannot be said for lenses with three or more components. Even the range of possible critical-curve topologies and caustic geometries of the three-point-mass lens remains unknown. In this paper we provide new tools for mapping the critical-curve topology and caustic cusp number in the parameter space of n-point-mass lenses. We perform our analysis in the image plane of the lens. We show that all contours of the Jacobian are critical curves of re-scaled versions of the lens configuration. Utilizing this property further, we introduce the cusp curve to identify cusp-image positions on all contours simultaneously. In order to track cusp-number changes in caustic metamorphoses, we define the morph curve, which pinpoints the positions of metamorphosis-point images along the cusp curve. We demonstrate the usage of both curves on simple two- and three-point-mass lens examples. For the three simplest caustic metamorphoses we illustrate the local structure of the image and source planes.

    in women randomized to HRT (1.94 +/- 4.86 kg) than in women randomized to no HRT (2.57 +/- 4.63, p = 0.046). A similar pattern was seen in the group receiving HRT or not by their own choice. The smaller weight gain in women on HRT was almost entirely caused by a lesser gain in fat. The main determinant...... of the weight gain was a decline in physical fitness. Women opting for HRT had a significantly lower body weight at inclusion than the other participants, but the results in the self-selected part of the study followed the pattern found in the randomized part. The change in fat mass was the strongest predictor...... of bone changes in untreated women, whereas the change in lean body mass was the strongest predictor when HRT was given. Body weight increases after the menopause. The gain in weight is related to a decrease in working capacity. HRT is associated with a smaller increase in fat mass after menopause. Fat...

    We calculated critical and subcritical masses of 10 fissionable actinides ( 233 U, 235 U, 238 Pu, 239 Pu, 241 Pu, 242m Am, 243 Cm, 244 Cm, 249 Cf and 251 Cf) in metal and in metal-water mixtures (except 238 Pu and 244 Cm). The calculation was made with a combination of a continuous energy Monte Carlo neutron transport code, MCNP-4B2, and the latest released version of the Japanese Evaluated Nuclear Data Library, JENDL-3.2. Other evaluated nuclear data files, ENDF/B-VI, JEF-2.2, and JENDL-3.3 in its preliminary version were also applied to find differences in results originated from different nuclear data files. For the so-called big three fissiles ( 233 U, 235 U and 239 Pu), analyzing the criticality experiments cited in ICSBEP Handbook validated the code-library combination, and calculation errors were consequently evaluated. Estimated critical and lower limit critical masses of the big three in a sphere with/without a water or SS-304 reflector were supplied, and they were compared with the subcritical mass limits of ANS-8.1.

    A parametric calculational analysis has been performed in order to estimate the minimum mass of moderator required for criticality of homogeneous low-enriched uranium systems. The analysis was performed using a version of the SCALE-4.0 code system and the 27-group ENDF/B-IV cross-section library. Water-moderated uranyl fluoride (UO{sub 2}F{sub 2} and H{sub 2}O) and hydrofluoric-acid-moderated uranium hexaflouride (UF{sub 6} and HF) systems were considered in the analysis over enrichments of 1.4 to 5 wt % {sup 235}U. Estimates of the minimum critical volume, minimum critical mass of uranium, and the minimum mass of moderator required for criticality are presented. There was significant disagreement between the values generated in this study when compared with a similar undocumented study performed in 1983 using ANISN and the Knight-modified Hansen-Roach cross sections. An investigation into the cause of the disagreement was made, and the results are presented.

    Post-menopausal osteoporosis is seen in all racial groups. With the increasing population and longevity of minority groups, osteoporosis is becoming an important health concern. Data regarding risk factors for, and prevalence of, low bone mass and awareness of osteoporosis risk in African American (AA) women are limited. This article evaluates the risk factors for, and prevalence of, low bone mass in a population of urban AA women in Wisconsin and assesses this group's perceived risk for osteoporosis. One hundred fifty consecutive community-dwelling AA women > or = 45 years old from Milwaukee, Wis were asked to complete a questionnaire based on currently accepted osteoporosis risk factors. Additionally, their perception of osteoporosis risk was assessed using a Likert scale. All subjects underwent quantitative calcaneal ultrasound. Subject mean age was 54 +/- 7 years. Mean T- and Z-scores were 0.5 and 0.4, respectively. Applying World Health Organization criteria, osteopenia (bone mineral density T-score 2 children), postmenopausal state, and current smoking were associated with lower calcaneal bone mass. Higher education and presence of diabetes were associated with a higher bone mass. Only 25% of the women surveyed thought they were at moderate to high risk for osteoporosis. Low bone mass was present in 33% of these AA women despite their relative young age. Many AA women do not perceive osteoporosis as a health risk. It is necessary to develop strategies to educate AA women regarding osteoporosis risk.

    This paper investigates the association between mass education and married women's experience with domestic violence in rural Nepal. Previous research on domestic violence in South Asian societies emphasizes patriarchal ideology and the widespread subordinate status of women within their communities and families. The recent spread of mass education is likely to shift these gendered dynamics, thereby lowering women's likelihood of experiencing domestic violence. Using data from 1775 currently married women from the Chitwan Valley Family Study in Nepal, we provide a thorough analysis of how the spread of mass education is associated with domestic violence among married women. The results show that women's childhood access to school, their parents' schooling, their own schooling, and their husbands' schooling are each associated with their lower likelihood of experiencing domestic violence. Indeed, husbands' education has a particularly strong, inverse association with women's likelihood of experiencing domestic violence. These associations suggest that the proliferation of mass education will lead to a marked decline in women's experience with domestic violence in Nepal. Copyright © 2015 Elsevier Inc.

    Muscle mass plays an important role in determining cardiovascular and metabolic risks in polycystic ovary syndrome (PCOS). In addition, whether lean mass influences carotid intima-media thickness (IMT) in PCOS has not been assessed. Prospective investigation. Ninety-five women with PCOS were age- and weight-matched to 90 ovulatory controls. All women had dual X-ray absorptiometry for lean, fat and bone mass, and bone mass density (BMD). Serum testosterone, sex hormone-binding globulin, insulin, and glucose and carotid IMT were determined. Free androgen index (FAI) and insulin resistance (by QUICKI) were calculated. In PCOS, waist circumference and insulin were higher and QUICKI lower than in controls (Plean mass were higher in PCOS compared to controls (PPCOS (PPCOS patients had abnormal (> or = 0.9 mm) values. Lean mass correlated with fat parameters, insulin, QUICKI, and FAI, but not with total testosterone; and after adjustments for insulin and QUICKI, lean mass still correlated with fat mass (PLean mass correlated with IMT (Plean mass independently of insulin. Bone mass correlated with lean and fat mass, but not with insulin or androgen. PCOS patients with 'pathological' IMT values had higher % trunk fat, lean mass, and insulin, lower QUICKI, and higher testosterone and FAI compared with those with normal IMT. Lean mass is increased in PCOS, while bone mass is similar to that of matched controls. The major correlates of lean mass are fat mass and insulin but not androgen. Lean mass also correlated with IMT, and although influenced by insulin, small changes in IMT may partially reflect changes in muscle mass, while clearly abnormal values relate to more severe abnormalities of PCOS.

  2. Towards a Discourse for Criticism in Language Teaching: Analysis of Sociocultural Representations in Mass Media

    Full Text Available This article states that in order to exercise citizenship with responsibility, language teachers need to popularize a discourse for criticism in which students and teachers transcend tacit knowledge and common sense due to meta-cognition and argumentation and reach systematic knowledge and procedures posed by experts in the different disciplines. As illustrated inside, the source and objective of analysis by means of which this discourse can be contextualized in language teaching is the language of mass media and all the sociocultural and signifying practices that it invokes. We conclude that through the analysis of mass media it is possible to educate students with the basic knowledge and skills necessary to interact critically in the world.

    Mass media is an important vehicle for health promotion in developing countries. In Bangladesh multiple media campaigns are being carried out to educate people about HIV/AIDS. We examined the extent of HIV/AIDS knowledge and the association of exposure to mass media among women in Bangladesh. The Bangladesh Demographic and Health Survey (BDHS) provides data for this article. We found that media exposure (combined index of television, radio, and newspaper) was a highly significant predictor of women's knowledge about HIV and AIDS. Other significant predictors of HIV knowledge include women's education, age, employment, and urban residence.

    Full Text Available Most studies have considered the negative influence of obesity on fertility in both genders. In the present study, we assessed mitochondrial activity expressed as the mitochondrial potential index (MPI in cumulus cells from obese women and women with a normal body mass index (BMI during assisted reproductive therapy. The results revealed a significant reduction of MPI with increased body mass. The lower MPI levels in cumulus cells from obese women may reflect mitochondrial dysfunction caused by oxidative stress, which can affect the cumulus-oocyte complex and have an impact on oocyte development.

    Shelters for abused women function within a broad context that includes intersecting social structures, policies, and resources, which may constrain and limit the options available to abused women and tacitly reinforce the cycle of abuse. This feminist, qualitative study combined in-depth interviews and focus groups conducted with 37 staff and four executive directors from four shelters in Ontario, Canada, along with a critical discourse analysis of salient policy texts. Together, the interviews and critical discourse analysis formed an integrated analysis of the dialectic between policy as written and enacted. The study findings illuminate the complexity of the system and its impact on women, shelters, and the community and highlight how specific types of social policies and various social system subsystems and structures, and system configuration, shape the day to day reality of shelter service delivery and impact outcomes for abused women and their children. Collectively, these findings offer direction regarding where these policies could be improved and provide a basis for shelters, policy makers, advocates, and the community to strengthen current services and policies, potentially enhancing outcomes for women. © The Author(s) 2015.

    Although HIV testing is critical to the treatment and prevention of HIV/AIDS, utilization rate of HIV testing services among married women and men remains low in Ghana. Mass media, as a tool to increase overall HIV testing turnouts, has been considered one of the important strategies in promoting and enhancing behavioural changes related to HIV/AIDS prevention. Using the 2014 Ghana Demographic and Health Survey, the current study examines the relationship between levels of exposure to print media, radio, and television and the uptake of HIV testing among married women and men in Ghana. Results show that HIV testing is more prevalent among married women than their male counterparts. We also find that higher levels of exposure to radio is associated with HIV testing among women, while higher levels of exposure to print media and television are associated with HIV testing among men. Implications of these findings are discussed for Ghana's HIV/AIDS strategic framework, which aims to expanding efforts at dealing with the HIV/AIDS epidemic. Specifically, it is important for health educators and programme planners to deliver HIV-related messages through television, radio, and print media to increase the uptake of HIV testing particularly among married women and men in Ghana.

    Obesity and weight gain is a critical public health concern. Serious digital games are gaining popularity in the context of health interventions. They use persuasive and fun design features to engage users in health-related behaviors in a non-game context. As a young field, research about effectiveness and acceptability of such games for weight loss is sparse. The goal of this study was to evaluate real-world play patterns of SpaPlay and its impact on body mass index (BMI) and nutritional knowledge. SpaPlay is a computer game designed to help women adopt healthier dietary and exercise behaviors, developed based on Self-Determination theory and the Player Experience of Need Satisfaction (PENS) model. Progress in the game is tied to real-life activities (e.g., eating a healthy snack, taking a flight of stairs). We recruited 47 women to partake in a within-subject 90-day longitudinal study, with assessments taken at baseline, 1-, 2-, and 3- months. Women were on average, 29.8 years old (±7.3), highly educated (80.9% had BA or higher), 39% non-White, baseline BMI 26.98 (±5.6), who reported at least contemplating making changes in their diet and exercise routine based on the Stages of Change Model. We computed 9 indices from game utilization data to evaluate game play. We used general linear models to examine inter-individual differences between levels of play, and multilevel models to assess temporal changes in BMI and nutritional knowledge. Patterns of game play were mixed. Participants who reported being in the preparation or action stages of behavior change exhibited more days of play and more play regularity compared to those who were in the contemplation stage. Additionally, women who reported playing video games 1-2 hours per session demonstrated more sparse game play. Brief activities, such as one-time actions related to physical activity or healthy food, were preferred over activities that require a longer commitment (e.g., taking stairs every day for a week

    Full Text Available Despite its post-Soviet history, Azerbaijan is an under-investigated country in academic research—compared with the other former constituencies, such as the Baltic countries or Russia, of the USSR—and gender questions of the contemporary Azerbaijani society are even less touched on. Within the current context of the post-“Arab Spring” era of mediatized connectivity and collective political engagement, this article looks into and analyzes how Azerbaijani women participate in different online and offline social and political movements, and if (and how they are impeded by the increased state authoritarianism in Azerbaijan. Using data, obtained from online information resources, yearly reports of human rights organizations, focus group discussions, and interviews, the study detects four major activist constellations within the Azerbaijani field of gendered politics. Based on the analysis of conditions of detected groups, the article claims that flash mobs, a tactic employed mainly by liberal activists, emerge as the promising way in overcoming the normative nature of Azerbaijani patriarchal society, thus providing an opportunity for normalization and internalization of the feeling of being on the street and acting in concert with others—the practices which might lead towards an increasing participation of (especially young women in the political processes of the country.

    Despite known positive association between body mass and bone mineral density (BMD), relative contribution of fat and lean tissue to BMD remains under debate. We aimed at investigating the effect of selected anthropometric parameters, including fat content and lean body mass (LBM) on BMD in postmenopausal, osteoporotic women with body mass index (BMI) > 20 kg/m(2). The study involved 92 never-treated women (mean age 69.5 ± 7.3). L1-L4 and femoral neck (FN) BMD were measured by dual energy X-ray absorptiometry (DEXA). Absolute (kg) and relative (%) fat and LBM were assessed by means of electric bioimpedance method. We showed both FN and L1-L4 BMD were positively correlated with body mass, waist circumference (WC), hip circumference (HC) and LBM (kg). Fat content correlated with FN BMD (r = 0.36, p obese. Obese women displayed the highest BMD. Both L1-L4 and FN BMD were higher in women with WC > 80 cm. In postmenopausal osteoporotic women with BMI > 20 kg/m(2) both fat and lean tissue might contribute to BMD. Positive association between body mass and BMD does not make obesity and osteoporosis mutually exclusive. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Our study compares the bone mass of Hawaiian, Filipino, Japanese, and white women living in Oahu, Hawaii. Eligible women ranged in age from 25 to 34; all had bone mass measurements at the spine, calcaneus, and proximal and distal radius. Their average bone mineral density (BMD) remained stable with age at all four bone sites, indicating that the age range 25-34 may represent the peak bone mass. Bone mass varied, however, between ethnicities; differences in BMD up to 11% were observed. The Hawaiian women had the greatest BMD, and whites had the second greatest BMD at the spine and calcaneus. The Japanese most frequently had the lowest BMD. Differences in body size partly explained the differences; most ethnic differences were reduced or eliminated after adjusting for height and weight. At the spine, the ethnic differences for BMD were also apparent with BMC and with vertebral area. Hawaiian and white women had greater values than Japanese or Filipino women. Differences at the proximal radius resembled the spine, except that whites had the widest proximal widths. The results were more complex for the distal radius. At the distal radius whites had the lowest BMD of the four ethic groups. The difference between whites and Hawaiians derived from the greater bone mineral content (BMC) of the Hawaiian women. By contrast, the difference between whites and the Japanese and Filipinos derived from the wider distal widths of the white women. Compared with the Japanese and Filipino women, the white women appeared to disperse their BMC at the distal radius across a wider bone width.(ABSTRACT TRUNCATED AT 250 WORDS)

    Femoral head diameter is commonly used to estimate body mass from the skeleton. The three most frequently employed methods, designed by Ruff, Grine, and McHenry, were developed using different populations to address different research questions. They were not specifically designed for application to female remains, and their accuracy for this purpose has rarely been assessed or compared in living populations. This study analyzes the accuracy of these methods using a sample of modern British women through the use of pelvic CT scans (n = 97) and corresponding information about the individuals' known height and weight. Results showed that all methods provided reasonably accurate body mass estimates (average percent prediction errors under 20%) for the normal weight and overweight subsamples, but were inaccurate for the obese and underweight subsamples (average percent prediction errors over 20%). When women of all body mass categories were combined, the methods provided reasonable estimates (average percent prediction errors between 16 and 18%). The results demonstrate that different methods provide more accurate results within specific body mass index (BMI) ranges. The McHenry Equation provided the most accurate estimation for women of small body size, while the original Ruff Equation is most likely to be accurate if the individual was obese or severely obese. The refined Ruff Equation was the most accurate predictor of body mass on average for the entire sample, indicating that it should be utilized when there is no knowledge of the individual's body size or if the individual is assumed to be of a normal body size. The study also revealed a correlation between pubis length and body mass, and an equation for body mass estimation using pubis length was accurate in a dummy sample, suggesting that pubis length can also be used to acquire reliable body mass estimates. This has implications for how we interpret body mass in fossil hominins and has particular relevance

    OBJECTIVE: We set out to compare measurement of Body Mass Index (BMI) with selfreporting in women early in pregnancy. STUDY DESIGN: We studied 100 women booking for antenatal care in the first trimester with a normal ongoing pregnancy. Selfreported maternal weight and height were recorded and the Body Mass Index was calculated. Afterwards maternal weight and height were digitally measured and actual BMI was calculated. RESULTS: If selfreporting is used for BMI classification, we found that 22% of women were classified incorrectly when BMI was measured. 12% of the women who were classified as having a normal selfreported BMI were overweight and 5% classified as overweight were obese. Similar findings have been reported outside pregnancy. CONCLUSIONS: These findings have implications for clinical practice, and for research studies exploring the relationship between maternal adiposity and pregnancy complications.

    Assessing skeletal muscle mass (SMM) is critical in studying and detecting sarcopenia. Direct measurements by MRI or computerized tomography are expensive or high in radiation exposure. Dual-energy X-ray absorptiometry (DXA) is promising for body composition assessments, but the validity of DXA for predicting SMM in the elderly is still under investigation. The objective of this study was to assess the relationship between DXA-derived measurements of lean soft tissue mass (LSTM) and SMM in older women. Study participants were postmenopausal women (n = 101) recruited in southern Arizona. Total and regional body composition was measured using MRI and DXA (QDR4500w). The participants' mean age was 70.7 +/- 6.4 y and their mean BMI was 27.4 +/- 5.1 kg/m2. DXA-derived LSTM was highly correlated with MRI-derived SMM for the whole body (r = 0.94; P LSTM assessments for the leg region but not for the total body. In conclusion, although the relationships between DXA measures and MRI-derived SMM vary by region of interest, the overall prediction of SMM by DXA is excellent. We conclude that DXA is a reliable method for cross-sectional assessments of SMM in older women.

    To assess patterns of recruitment into a community-based NCI-funded physical activity and dietary lifestyle change program targeting African-American women. Acquisition of a convenience sample to be screened for participation in a randomized, controlled prevention intervention. African-American-owned and -operated health club located in an area of Los Angeles in which African Americans are concentrated. 893 African-American women. RECRUITMENT STRATEGIES: Social networking/word-of-mouth, staff presentations, mass and targeted media, and physician referral. Completion of screening questionnaire indicating a desire to enroll in the study. Screening questionnaire domains included self-reported height and weight, recent participation in organized weight loss programs, ability to walk one mile unassisted, current medication use, smoking status, personal medical history of cancer, sociodemographic variables, and recruitment source. Sociodemographic and anthropometric characteristics distinguished between respondents obtained through different recruitment strategies. In particular, women with a higher body mass index (BMI) were more likely than those with lower BMIs (P = .014) to be recruited through more personalized methods (eg, social networking). Culturally tailored recruitment strategies are critical in securing the participation of members of "hard-to-reach" populations, who are both under-represented in health promotion research and at high risk for chronic diseases.

    To determine whether women with sarcopenia and low bone mineral density (BMD) are at greater risk of clinical fractures than those with sarcopenia or low BMD alone. Women's Health Initiative (WHI) Observational and Clinical trials. Three U.S. clinical centers (Pittsburgh, PA; Birmingham, AL; Phoenix/Tucson, AZ). Women (mean age 63.3 ± 0.07) with BMD measurements (N = 10,937). Sarcopenia was defined as appendicular lean mass values corrected for height and fat mass. Low BMD was defined as a femoral neck T-score less than -1.0 based on the Third National Health and Nutrition Examination Survey reference database for white women. Cox proportional hazards analysis was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). We followed women for incident fractures over a median of 15.9 years. Participants were classified into mutually exclusive groups based on BMD and sarcopenia status: normal BMD and no sarcopenia (n = 3,857, 35%), sarcopenia alone (n = 774, 7%), low BMD alone (n = 4,907, 45%), and low BMD and sarcopenia (n = 1,399, 13%). Women with low BMD, with (HR = 1.72, 95% CI = 1.44-2.06) or without sarcopenia (HR = 1.58, 95% CI = 1.37-1.83), had greater risk of fracture than women with normal BMD; the difference remained statistically significant after adjustment for important covariates. Women with low BMD, with (HR = 2.78, 95% CI = 1.78-4.30 and without (HR = 2.42, 95% CI = 1.63-3.59) sarcopenia had higher risk of hip fractures. Women with sarcopenia alone had similar HRs to women with normal BMD. Compared to women with normal BMD. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    The study on structure of critically safe multistage mixer-settler for the extraction process of high enriched uranium and plutonium has been completed. The mixer-settler has simple structure, good critical safety, flexibility in operation (O/A from 0.5 to 5) and high extraction efficiency (E x > 90%). These performances have been proved in the hydrodynamics and mass transfer experiments at a three stages cascade mixer-settler. Based on the others experience, a trapezoidal impeller combined with half-open turbine is developed which has stronger pumping and well mixing function at low rotating speed. The optimal rotating speed is 250 to 280 r/min obtained by experiments

    1999-01-01

    Critical masses of bare homogeneous spherical UO 2 -water mixtures at various intermediate fissile enrichments determined by multigroup, transport theory is presented. This work was performed to provide support for particular issues encountered by the nuclear industry when operating in the intermediate enrichment regime, namely, the validation of codes used to set criticality safety limits. Validation is normally performed with a comparison of computational results and applicable experiments. However, this may be difficult in some cases because of the lack of sufficient applicable experiments in the intermediate enrichment range. If a large extension of the area of applicability from an experiment to the desired application exists, then an alternative means for validation must be employed. Ideal interpretations of standard ANSI/ANS 8.1 Section 4.3 (1983) implies that perhaps an independent code and data system may be employed for validation purposes

  1. Safety analysis report for the Hanford Critical Mass Laboratory: Supplement No. 2. Experiments with heterogeneous assemblies

    Factors affecting the safety of criticality experiments using heterogeneous assemblies are described and assessed. It is concluded that there is no substantial change in safety from experiments already being routinely performed at the Critical Mass Laboratory (CML), and that laboratory and personnel safety are adequately provided by the combination of engineered and administrative safety limits enforced at the CML. This conclusion is based on the analysis of operational controls, potential hazards, and the consequences of accidents. Contingencies considered that could affect nuclear criticality include manual changes in fuel loadings, water flooding, fire, explosion, loss of services, earthquake, windstorm, and flood. Other potential hazards considered include radiation exposure to personnel, and potential releases within the Assembly Room and outside to the environment. It is concluded that the Maximum Credible Nuclear Burst of 3 x 10 18 fissions (which served as the design basis for the CML) is valid for heterogeneous assemblies as well as homogeneous assemblies. This is based upon examination of the results of reactor destructive tests and the results of the SL-1 reactor destructive accident. The production of blast effects which might jeopardize the CML critical assembly room (of thick reinforced concrete) is not considered credible due to the extreme circumstances required to produce blast effects in reactor destructive tests. Consequently, it is concluded that, for experiments with heterogeneous assemblies, the consequences of the Maximum Credible Burst are unchanged from those previously estimated for experiments with homogeneous systems

    The major limit in the thermalhydraulic design of water cooled reactors consists in the occurrence of critical heat flux, which is verified by correlation of large range of validity. In the present work, the major design correlations were analyzed, through comparisons with experimental data, for utilization in PWR with low mass flux in the core. The results show that the EPRI correlation, with modifications, gives conservative results, from the safety point of view, with lower data spreading, being the most indicated for the reactor thermal design.

    Alteration of menstrual cycle by individual lifestyles and unfavorable habits may cause menstrual irregularity. We aimed to investigate the relationship between lifestyle factors and menstrual irregularity in Korean women using data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. This cross-sectional study included 3779 nondiabetic Korean women aged 19-49 years who did not take any oral contraceptives or sex hormonal compounds. We examined the association of menstrual irregularity with age, body mass index (BMI), drinking experience, and smoking habits. Age, Asian BMI, marriage status, age at menarche, and smoking habits were significantly associated with menstrual cycle irregularity (p smoking habits in middle-aged women aged 30-39 years (p smoking habits in nondiabetic Korean women.

    Endometriosis is a disabling and long-term medical condition affecting quality of life and mental health. Behavioral, cognitive, and emotional coping strategies, emotional intelligence, and metacognition could in part explain the link between the disease and impaired psychological and life functioning. This critical narrative review aimed at examining the state of the art of the relationships between endometriosis and these factors. According to PRISMA principles, we performed a systematic search for quantitative and qualitative studies on multiple electronic databases as regards coping strategies, emotional intelligence, and metacognition in women with endometriosis. Studies were subjected to interpretative and critical narrative synthesis. A total of 9 papers were included in the review. Three main categories were identified in thematic analysis and resumed in the manuscript. Findings suggested that (a) pain is considered the major stressor; (b) they usually use both adaptive and maladaptive coping strategies; (c) women with endometriosis and related chronic pain seem to repress emotions more likely than healthy ones; (d) suppressing own emotions, pain catastrophizing, and having a passive coping style are related to higher self-reported pain; and (e) emotional and avoidance coping styles are associated to poor mental status, while positive coping strategies focusing on the problem or on emotions, detached and rational styles are associated to better mental health. Few studies with mixed results and some methodological flaws have focused on coping strategies in women with endometriosis. No studies focusing on metacognition or emotional intelligence were found. Methodological biases, suggestions for future research, and implications for clinical practice were discussed.

    This study investigated the effects of progressive resistance training (PRT) on lean muscle mass (LMM) in women with or without polycystic ovary syndrome (PCOS) and its effects on metabolic factors and concentrations of related steroid hormones. This was a nonrandomized, therapeutic, open, single-arm study. All in all, 45 sedentary women with PCOS and 52 without (non-PCOS), 18-37 yr of age, with body mass indexes (BMI) of 18-39.9 kg·m(-2) of all races and social status, performed PRT three times a week for 4 months. Before and after PRT, the concentrations of hormones and metabolic factors and waist circumference were measured. LMM and total body fat percentage were determined using dual-energy x-ray absorptiometry. Clinical characteristics, LMM, and fasting glucose were adjusted for confounding covariables and compared using general linear mixed models. Each patient's menstrual history was taken before study enrollment and after PRT. PRT resulted in reduced plasma testosterone and fasting glucose levels. After PRT, the androstenedione concentration increased and the sex hormone-binding globulin concentration decreased in women with PCOS. The waist circumference was reduced (P lean mass (LM)/height2, increased in women with PCOS (P = 0.04). Women with PCOS showed increased muscle mass indexes of appendicular LM/height2 (P = 0.03) and LM/height2 (P women with PCOS (P = 0.01) at the baseline and after PRT. To our knowledge, this is the first report to show that resistance exercise alone can improve hyperandrogenism, reproductive function, and body composition by decreasing visceral fat and increasing LMM, but it has no metabolic impact on women with PCOS.

    to identify and analyse qualitative literature exploring women's experiences of coping with pain during childbirth. critical review of qualitative research. ten studies were included, conducted in Australia, England, Finland, Iceland, Indonesia, Iran and Sweden. Eight of the studies employed a phenomenological perspective with the remaining two without a specific qualitative methodological perspective. Thematic analysis was used as the approach for synthesising the data in this review. Two main themes emerged as the most significant influences upon a woman's ability to cope with pain: (i) the importance of individualised, continuous support and (ii) an acceptance of pain during childbirth. This review found that women felt vulnerable during childbirth and valued the relationships they had with health professionals. Many of the women perceived childbirth pain as challenging, however, they described the inherent paradox for the need for pain to birth their child. This allowed them to embrace the pain subsequently enhancing their coping ability. women's experience of coping with pain during childbirth is complex and multifaceted. Many women felt the need for effective support throughout childbirth and described the potential implications where this support failed to be provided. Feeling safe through the concept of continuous support was a key element of care to enhance the coping ability and avoid feelings of loneliness and fear. A positive outlook and acceptance of pain was acknowledged by many of the women, demonstrating the beneficial implications for coping ability. These findings were consistent despite the socio-economic, cultural and contextual differences observed within the studies suggesting that experiences of coping with pain during childbirth are universal. the findings suggest there is a dissonance between what women want in order to enhance their ability to cope with pain and the reality of clinical practice. This review found women would like health

  10. Targeting Policy for Obesity Prevention: Identifying the Critical Age for Weight Gain in Women

    Full Text Available The obesity epidemic requires the development of prevention policy targeting individuals most likely to benefit. We used self-reported prepregnancy body weight of all women giving birth in Nova Scotia between 1988 and 2006 to define obesity and evaluated socioeconomic, demographic, and temporal trends in obesity using linear regression. There were 172,373 deliveries in this cohort of 110,743 women. Maternal body weight increased significantly by 0.5 kg per year from 1988, and lower income and rural residence were both associated significantly with increasing obesity. We estimated an additional 82,000 overweight or obese women in Nova Scotia in 2010, compared to the number that would be expected from obesity rates of just two decades ago. The critical age for weight gain was identified as being between 20 and 24 years. This age group is an important transition age between adolescence and adulthood when individuals first begin to accept responsibility for food planning, purchasing, and preparation. Policy and public health interventions must target those most at risk, namely, younger women and the socially deprived, whilst tackling the marketing of low-cost energy-dense foods at the expense of healthier options.

    We examined the relationship between low bond mass and metabolic syndrome in 2,475 Korean women. After adjustment for all covariates, mean vertebral BMD was significantly lower in women with metabolic syndrome. Moreover, age and weight adjusted vertebral BMD was significantly decreased with additional components of the metabolic syndrome. Obesity-induced chronic inflammation is a key component in the pathogenesis of insulin resistance and metabolic syndrome. It has been suggested that proinflammatory cytokines and low-grade systemic inflammation activate bone resorption and may lead to reduced bone mineral density (BMD). The objective of this study was to determine the relationship between low bone mass and metabolic syndrome in Korean women. This is a cross-sectional study of 2,548 women aged 18 years and over who had visited the Health Promotion Center. Physical examination and laboratory tests were performed. Vertebral BMD was measured using dual-energy X-ray absorptiometry. Metabolic syndrome was defined by National Cholesterol Education Program-Adult Treatment Panel III criteria. Among 2,475 women, 511 (21.0%) women had metabolic syndrome. Women with abdominal obesity or hypertriglyceridemia had significantly lower vertebral BMD than women without respective components after adjustment for age, weight, and height. After adjustment for all covariates, mean vertebral BMD was significantly lower in women with metabolic syndrome (p = 0.031). Moreover, age- and weight-adjusted vertebral BMD were significantly decreased with additional components of the metabolic syndrome (p = 0.004). These findings suggest that metabolic syndrome might be another risk factor for osteoporosis and related fractures.

    This research examines young unmarried women's ways of talking about AIDS, AIDS prevention, and its relationship to mass media AIDS messages in Thailand. Data were derived from a survey conducted in four districts of Kanchanaburi province. Three hundred ninety-seven unmarried women were extracted from the approximately 1,800 original subjects for this analysis. Respondents were asked about the subjects and extent of their conversations about AIDS, the choice of discussion partners, considerations of social appropriateness in talking about the disease, as well as their risk perception. Important findings were that (a) women tend to talk about AIDS primarily with friends and siblings, (b) their reception level of mass media messages is related to the number of topics discussed and frequency of talks by the subjects, and (c) socioeconomic status and age are related to the variety and frequency of talking about AIDS. Implications for AIDS education are discussed.

    Full Text Available Abstract Background It has been reported that there is an inverse association between osteoarthritis (OA and osteoporosis. However, the relationship of bone mass to OA in a Japanese population whose rates of OA are different from Caucasians remains uncertain. Methods We studied the association of appendicular bone mineral density (second metacarpal; mBMD and quantitative bone ultrasound (calcaneus; stiffness index with knee and hand OA among 567 Japanese community-dwelling women. Knee and hand radiographs were scored for OA using Kellgren-Lawrence (K/L scales. In addition, we evaluated the presence of osteophytes and of joint space narrowing. The hand joints were examined at the distal and proximal interphalangeal (DIP, PIP and first metacarpophalangeal/carpometacarpal (MCP/CMC joints. Results After adjusting for age and body mass index (BMI, stiffness index was significantly higher in women with K/L scale, grade 3 at CMC/MCP joint compared with those with no OA. Adjusted means of stiffness index and mBMD were significantly higher in women with definite osteophytes at the CMC/MCP joint compared to those without osteophytes, whereas there were no significant differences for knee, DIP and PIP joints. Stiffness index, but not mBMD, was higher in women with definite joint space narrowing at the CMC/MCP joint compared with those with no joint space narrowing. Conclusions Appendicular bone mass was increased with OA at the CMC/MCP joint, especially among women with osteophytes. Our findings suggest that the association of peripheral bone mass with OA for knee, DIP or PIP may be less clearcut in Japanese women than in other populations.

    Bone mass decreases along with aging, especially for women after menopause because of lower estrogen secretion together with low calcium intake. This study was conducted to study the effect of eggshell calcium supplementation on bone mass in 54 postmenopausal Vietnamese women living in a farming area about 60 km from Hanoi, Vietnam. Sets of 3 subjects matched by age, bone mass, BMI and calcium intake were divided randomly into 3 groups with 18 subjects in each group. The eggshell calcium group was administered 300 mg/d calcium from eggshell, the calcium carbonate group 300 mg/d calcium from calcium carbonate and the placebo group received no calcium supplementation. Bone mass (Speed of Sound (SOS)) was measured at the beginning (the baseline), the middle (6th month) and the end of the study (12th month) by the single blind method. SOS of the eggshell group increased significantly at 12 mo (p0.05). In conclusion, eggshell calcium was more effective in increasing bone mass than calcium carbonate in postmenopausal Vietnamese women.

    Anatomic parameters determining renal mass complexity have been used in a number of proposed scoring systems despite lack of a critical analysis of their independent contributions. We sought to assess the independent contribution of anatomic parameters on perioperative outcomes of laparoscopic partial nephrectomy (LPN). Preoperative imaging studies were reviewed for 147 consecutive patients undergoing LPN for a single renal mass. Renal mass anatomy was recorded: Size, growth pattern (endo-/meso-/exophytic), centrality (central/hilar/peripheral), anterior/posterior, lateral/medial, polar location. Multivariable models were used to determine associations of anatomic parameters with warm ischemia time (WIT), operative time (OT), estimated blood loss (EBL), intra- and postoperative complications, as well as renal function. All models were adjusted for the learning curve and relevant confounders. Median (range) tumor size was 3.3 cm (1.5-11 cm); 52% were central and 14% hilar. While 44% were exophytic, 23% and 33% were mesophytic and endophytic, respectively. Anatomic parameters did not uniformly predict perioperative outcomes. WIT was associated with tumor size (P=0.068), centrality (central, P=0.016; hilar, P=0.073), and endophytic growth pattern (P=0.017). OT was only associated with tumor size (Panatomic parameter predicted EBL. Tumor centrality increased the odds of overall and intraoperative complications, without reaching statistical significance. Postoperative renal function was not associated with any of the anatomic parameters considered after adjustment for baseline function and WIT. Learning curve, considered as a confounder, was independently associated with reduced WIT and OT as well as reduced odds of intraoperative complications. This study provides a detailed analysis of the independent impact of renal mass anatomic parameters on perioperative outcomes. Our findings suggest diverse independent contributions of the anatomic parameters to the

    To describe associations between eating behaviors, dietary intake, physical activity, attitudes toward diet and health, sociodemographic variables and body mass index (BMI) among women and children, and differences by household income. Data from the 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII) and the Diet and Health Knowledge Survey (DHKS) were examined using multivariate regression to estimate the associations between BMI and behavioral and environmental variables among women and children. CSFII 1994-1996 is representative of the US population. DHKS surveyed CSFII respondents 20 y of age and over. Our samples consisted of 2419 adult women and 1651 school-age children. CSFII respondents reported 24 h recalls of all food intakes on 2 nonconsecutive days and their personal and household characteristics, including self-reported height and weight. DHKS collected data on knowledge and attitudes toward dietary guidance and health from CSFII adult respondents. Significant correlations between women's BMI and age, race, dietary patterns, TV watching, and smoking was observed among women from both low- and high-income households. Beverage consumption, eating out, the importance of maintaining healthy weight, and exercise were correlated with BMI only among women from high-income households. Among children, age, race, income, and mother's BMI were significantly correlated with child BMI. Among women, the associations between some behavioral and environmental factors and BMI differ by household income. Intervention programs need to target specific eating and physical activity behaviors to promote a healthy body weight.

    Overweight and obesity are increasing at an alarming rate among older people. This is mainly because this population is predominantly sedentary. The aim of this study was to classify, according to the body mass index (BMI), a group of older active women and to evaluate the different basic physical abilities as a function of this. The BMI and fitness were evaluated in 60 elderly active women (mean age: 66.14 ± 6.59 years) using the 2-minute step test, arm curl test, chair stand test, back scratch test, chair-sit and reach-test, flamenco test, and 8-foot up-and-go test. It was found that 52.23% of the women studied had a normal BMI and 47.76% were slightly overweight. There were no cases of obesity or underweight. Women with normal BMI had better values in all tests than overweight women. Significant differences were found in the flamenco test (P<.05), and 8-foot up-and-go test (P<.01). Older women who usually do physical activity had a normal or slightly overweight BMI. It was also found that women with lower BMI have better resistance, flexibility, balance and strength.

    2015-01-01

    This paper provides a critical assessment of efforts to involve men in the prevention of men's violence against women. Although there is a substantial evidence base attesting to the effectiveness of at least some strategies and interventions, this field is also limited in important ways. Violence prevention efforts often have focused on changing men's attitudes, rather than also seeking to transform structural and institutional inequalities. While feminist and queer scholarship has explored diversities and pluralities in the organisation of sexuality, much violence prevention work often assumes a homogenously heterosexual male constituency. Too often this work is conceptually simplistic with regard to gender. Against this background, this paper contests and complicates several assumptions that are part of an emerging consensus in men's violence prevention: first, that it is in men's interests to support progress towards non-violence and gender equality; second, that the best people to engage and work with men are other men; and finally, the strengths and limitations of inviting and drawing on 'real men'. A critical assessment of the field's working assumptions is vital if it is to contribute to the future prevention of men's violence against women.

    2012-08-01

    Australia, like other countries in neo-liberal democracies, is grappling with the gendered health 'problem' of depression. More concerning is the issue of recovery and relapse, with depression being the third largest cause of disability-adjusted life years (DALY). In addition, advanced liberal discourses of health position recovery as an exercise of individual responsibility to return to a functioning and productive norm and prevent recurrence. This moral enterprise of health articulates a 'recovery imperative' which overlooks the gendered context which may have created the conditions for women's depression and may in turn impede their recovery. Drawing on insights from governmentality and feminist post-structuralism, the article critically examines the effects of normalized recovery discourses on women's subjectivities. Data for the study were collected between 2005 and 2007 through in-depth interviews with 31 mid-life Australian women. Three key themes; 'in' recovery, 'eight out of ten' recovered, and recovering the authentic self, illustrate how the 'recovery imperative' may be implicated in perpetuating the cycle of recovery and relapse.

We aimed to investigate whether the most critical period occurs during childhood or later, during adolescence. Using a population-based case-control study (1586 cases and 2800 controls), individuals with different body sizes at age 10 and different body mass indices at age 20 were compared regarding MS risk, by calculating odds ratios with 95% confidence intervals. Potential interactions between HLA-DRB1*15 and absence of HLA-A*02, respectively, and both childhood and adolescent obesity were evaluated by calculating the attributable proportion due to interaction. Regardless of body size at age 10, individuals with adolescent obesity had a 90% increased risk of MS. Among participants who were not obese at age 20, no association was observed between body size at age 10 and subsequent MS risk. An interaction was observed between the HLA MS risk genes and adolescent, but not childhood, obesity. Our results suggest that BMI during adolescence, rather than childhood, is critical in determining MS risk. © The Author(s), 2015.

    Full Text Available Background With the rapid advancement of technology, mass media acquired widespread exposure upon major portion of the world population. The overall media platform has smooth access into peoples’ everyday lifestyle through routine tele transmission of all the existing media (such as broadcast, print, digital, outdoor media etc.. Mass media platform is one of the few most powerful influential factors causing dynamic behavioral changes. Objective To assess mass media exposure and it’s changing trends in Bangladesh using data from the Bangladesh Demographic and Health Survey (BDHS from 1993- 94 to 2014. Methods The study used data from the published reports of Bangladesh Demographic and Health Surveys (BDHS 1993-1994 to BDHS 2014. Results In the years of 1999-2000, 2004, 2007, 2014 women aged 20-24 years (41%, 54%, 56%, 57% respectively have passed more time watching television in weekly basis than the other age groups. Higher percentage was observed among the educated women than uneducated from 1999-2000 to 2014 who has made access to all three media (television, radio and newspaper at least once a week. Proportion of women who had accessed all three media at least once a week was much higher in the highest quintile families than the lowest quintile families and more exposure in urban women than the rural women. The region-wise coverage was higher in 1999-2000 in case of Chittagong (5.2%, Dhaka (4.7%, Khulna (5.1%, Rajshahi (3.1%, and Sylhet (3.9% division with access to all three media at least once a week except Barisal division. Conclusion Findings show higher percentage of television watching tendency among comparatively more educated and economically flourished urban women. Therefore, the major policy challenge addressees the need for designing of communications strategies targeting the less privileged, rural and illiterate people who constitute the majority of population in Bangladesh.

    We consider minimizers of the following mass critical Hartree minimization problem: eλ(N ) ≔inf {u ∈H1(Rd ) , ‖u‖2 2=N } Eλ(u ) , where d ≥ 3, λ > 0, and the Hartree energy functional Eλ(u) is defined by Eλ(u ) ≔∫Rd|∇u (x ) |2d x +λ ∫Rdg (x ) u2(x ) d x -1/2 ∫Rd∫Rdu/2(x ) u2(y ) |x -y |2 d x d y . Here the steep potential g(x) satisfies 0 =g (0 ) =infRdg (x ) ≤g (x ) ≤1 and 1 -g (x ) ∈Ld/2(Rd ) . We prove that there exists a constant N* > 0, independent of λg(x), such that if N ≥ N*, then eλ(N) does not admit minimizers for any λ > 0; if 0 N N*, then there exists a constant λ*(N) > 0 such that eλ(N) admits minimizers for any λ > λ*(N) and eλ(N) does not admit minimizers for 0 N). For any given 0 N N*, the limit behavior of positive minimizers for eλ(N) is also studied as λ → ∞, where the mass concentrates at the bottom of g(x).

    The objective of this study was to examine the effect of self-reported breakfast size, daily eating, and other health habits on body mass index (BMI). We hypothesized that a consumption of a substantial breakfast compared with skipping or small breakfasts would be associated with lower BMI. Three independent, cross-sectional, screening surveys were conducted by Sydney Adventist Hospital in 1976, 1986, and 2005 in the surrounding community. The archived survey forms of 384 men and 338 women in 1976, 244 men and 229 women in 1986, and 270 men and 62 women in 2005 were randomly selected. Body mass index was determined from height and weight measured by hospital staff. The reported amount consumed at breakfast was one of several eating habits that predicted BMI for men but not women. It explained 5% to 6% of the variance in male BMI in all 3 years examined. As the reported breakfast amount increased, men's BMI decreased. Lifestyle confounders including vegetarianism and physical activity did not affect this relationship. However, the consumption of breakfast was significantly positively associated with consumption of cereals, bread, fruit, and spreads, while coffee consumption was significantly associated with smaller breakfasts or breakfast skipping. The consumption of relatively large breakfasts may influence BMI in men, and its promotion may help reduce the prevalence of obesity in Australia and elsewhere. Copyright 2010 Elsevier Inc.

    Full Text Available Background :Obesity has become a major health problem across the world. In women, it is known to cause anovulation, subfecundity, increased risk of fetal anomalies and miscarriage rates. However, in women going for assisted reproduction the effects of obesity on egg quality, embryo quality, clinical pregnancy, live birth rates are controversial. Objectives :To assess the effect of women′s body mass index (BMI on the reproductive outcome of non donor In vitro fertilization (IVF/Intracytoplasmic sperm injection (ICSI. The effects of BMI on their gonadotrophin levels (day 2 LH, FSH, gonadotrophin dose required for ovarian stimulation, endometrial thickness and oocyte/embryo quality were looked at, after correcting for age and poor ovarian reserve. Materials and Methods : Retrospective study of medical records of 308 women undergoing non donor IVF cycles in a University affiliated teaching hospital. They were classified into three groups: normal weight (BMI25 30 kg/m 2 . All women underwent controlled ovarian hyper stimulation using long agonist protocol. Results : There were 88 (28.6% in the normal weight group, 147 (47.7% in the overweight and 73 (23.7% in the obese group. All three groups were comparable with respect to age, duration of infertility, female and male causes of infertility. The three groups were similar with respect to day 2 LH/FSH levels, endometrial thickness and gonadotrophin requirements, oocyte quality, fertilization, cleavage rates, number of good quality embryos and clinical pregnancy rates. Conclusion :Increase in body mass index in women does not appear to have an adverse effect on IVF outcome. However, preconceptual counselling for obese women is a must as weight reduction helps in reducing pregnancy-related complications.

  13. An application of the 'end-point' method to the minimum critical mass problem in two group transport theory

    Williams, M.M.R.

    2003-01-01

    A two group integral equation derived using transport theory, which describes the fuel distribution necessary for a flat thermal flux and minimum critical mass, is solved by the classical end-point method. This method has a number of advantages and in particular highlights the changing behaviour of the fissile mass distribution function in the neighbourhood of the core-reflector interface. We also show how the reflector thermal flux behaves and explain the origin of the maximum which arises when the critical size is less than that corresponding to minimum critical mass. A comparison is made with diffusion theory and the necessary and somewhat artificial presence of surface delta functions in the fuel distribution is shown to be analogous to the edge transients that arise naturally in transport theory

    This article explores cross-sectional associations between depressive symptoms and body mass index (BMI) in women working in schools in the Greater New Orleans area. Self-efficacy for eating and exercise, eating styles, and exercise are examined as potential pathways. This is a secondary data analysis of 743 women who were participating in a workplace wellness randomized controlled trial to address environmental factors influencing eating and exercise behaviors using baseline data prior to the intervention. BMI was the primary outcome examined. Path analysis suggested that increased depressive symptoms were associated with increased BMI in women. Indirect effects of depressive symptoms on BMI were found for increased healthy eating self-efficacy, increased emotional eating, and decreased exercise self-efficacy. The association between greater healthy eating self efficacy and BMI was unexpected, and may indicate a suppressor effect of eating self-efficacy in the relationship between depressive symptoms and BMI in women. The findings suggest the importance of depressive symptoms to BMI in women. Targets for interventions to reduce BMI include targeting depressive symptoms and related sequelae including self-efficacy for exercise, and emotional eating. Further investigation of eating self-efficacy and BMI are recommended with particular attention to both efficacy for health eating and avoidance of unhealthy foods.

    2011-01-01

    Using African American women's insights on their own health experiences, we explored how their daily life management was linked to the "strong Black woman" (SBW) script, and the health implications of that script. Using the search term "strong Black woman," we identified 20 articles from African American women's magazines and 10 blog sites linked to the SBW script and analyzed their content. We created thematic categories (role management, coping, and self-care) and extracted issues relevant to African American women's health. Adherence to the SBW script was linked to women's daily life management and health experiences. Themes such as self-sacrificial role management ("please the masses"), emotional suppression ("game face"), and postponement of self-care ("last on the list") incited internal distress and evinced negative health consequences. Scientists, activists, and health care professionals would be aided in forming initiatives aimed at reducing health disparities among African American women by heeding the insights on their health experiences that they express in popular media sources.

  17. The Effects of Moon’s Uneven Mass Distribution on the Critical Inclinations of a Lunar Orbiter

    2014-12-01

    Full Text Available The uneven mass distribution of the Moon highly perturbs the lunar spacecrafts. This uneven mass distribution leads to peculiar dynamical features of the lunar orbiters. The critical inclination is the value of inclination which keeps the deviation of the argument of pericentre from the initial values to be zero. Considerable investigations have been performed for critical inclination when the gravity field is assumed to be symmetric around the equator, namely for oblate gravity field to which Earth’s satellites are most likely to be subjected. But in the case of a lunar orbiter, the gravity field of mass distribution is rather asymmetric, that is, sectorial, and tesseral, harmonic coefficients are big enough so they can’t be neglected. In the present work, the effects of the first sectorial and tesseral harmonic coefficients in addition to the first zonal harmonic coefficients on the critical inclination of a lunar artificial satellite are investigated. The study is carried out using the Hamiltonian framework. The Hamiltonian of the problem is cconstructed and the short periodic terms are eliminated using Delaunay canonical variables. Considering the above perturbations, numerical simulations for a hypothetical lunar orbiter are presented. Finally, this study reveals that the critical inclination is quite different from the critical inclination of traditional sense and/or even has multiple solutions. Consequently, different families of critical inclination are obtained and analyzed.

    Insulin resistance is common in women with polycystic ovary syndrome (PCOS). Muscle is the major tissue utilizing glucose while excess adipose tissue relates to insulin resistance. Thus, body composition is likely to be an important regulator of insulin sensitivity. Thirty-nine PCOS patients (age: 29.9±1.0 years; BMI: 33.8±1.2 kg/m(2)) participated in a cross sectional study. Body composition was measured by dual energy x-ray absorptiometry (DEXA). Insulin resistance and secretion were assessed using oral glucose tolerance test (OGTT) and frequently sampled intravenous glucose tolerance test (FS-IVGTT). In contrast with the conventional expectations, lean mass correlated directly (Plean mass (52.8±1.8 vs 44.4±1.6 kg), those with higher lean mass had a higher glucose response during OGTT (AUC(Glucose); P=.034). In contrast, 17 pairs matched for lean mass (48.7±1.7 and 48.9±1.6 kg) but discordant for fat mass (43.3±2.6 vs 30.3±8.9 kg) showed no differences in insulin resistance parameters. These novel findings indicate that lean mass relates directly to insulin resistance in PCOS. Published by Elsevier Inc.

    To assess the usefulness of sonography in the evaluation of palpable mass in patients less than 35 years old,the breast sonograms and mammograms of 105 histopathologically proved cases were retrospectively reviewed. Breast parenchymal patterns on mammogram, sensitivity of sonography and mammography in the diagnosis of palpable breast masses, and sonographic findings of breast masses were analyzed. Grade IV breast parenchymal pattern was demonstrated in 44 of 76 mammogram (57.9%). The incidence of Grade IV pattern increased, as the patients' age became younger. The sensitivity of sonography (81.3%) was higher than that of mammography (45.3%) in the evaluation of the benign breast lesions. However, the sensitivity of both modalities were nearly equal (66.7% and 58.3% respectively) in the evaluation of the breast cancers. Sonographic findings of fibroadenoma included oval,well defined border, smooth contour, weak homogeneous internal echoes, posterior sonic enhancement, and bilateral shadows. On the other hand, breast cancer exhibited poorly defined border, irregular contour, and inhomogeneous hypoechoic mass with posterior sonic attenuation. In summary, sonography was useful in the evaluation of the palpable breast mass in women less than 35 years old. Choreoathetotic sonographic findings might help the differential diagnosis of breast masses

    1983-01-01

    The Trombay criticality formula (TCF) has been derived by incorporating a number of well-known concepts of criticality physics to enable prediction of changes in critical size or k /SUB eff/ following alterations in geometrical and physical parameters of uniformly reflected small reactor assemblies characterized by large neutron leakage from the core. The variant parameters considered are size, shape, density and diluent concentration of the core, and density and thickness of the reflector. The effect of these changes (except core size) manifests, through sigma /SUB c/ the critical surface mass density of the ''corresponding critical core,'' that sigma, the massto-surface-area ratio of the core,'' is essentially a measure of the product /rho/ extended to nonspherical systems and plays a dominant role in the TCF. The functional dependence of k /SUB eff/ on sigma/sigma /SUB c/ , the system size relative to critical, is expressed in the TCF through two alternative representations, namely the modified Wigner rational form and, an exponential form, which is given

    Are differences in metabolic dysfunction between polycystic ovary syndrome (PCOS) and control women related to differences in their fat to lean mass (F/L) ratio? Compared with controls of similar body mass index (BMI), women with PCOS demonstrate adverse body composition characterized by increased whole body fat relative to lean mass (i.e. a higher F/L ratio), which is associated with differences in metabolic dysfunction between the two groups. Previous studies examining body composition and insulin resistance (IR) in PCOS have yielded conflicting results. Excess total fat mass (i.e. fat mass index [fat BMI]) correlates with IR, whereas increased total lean mass (i.e. lean BMI) has been associated with higher insulin sensitivity. However, the role of the F/L ratio, which integrates the antagonistic effects of both fat and lean mass depots, on IR in PCOS, has not been investigated. We conducted a prospective cross-sectional study of 120 women between the ages of 22-44 years to study the relation of the F/L ratio with measures of insulin action and secretion in both steady and dynamic states. Sixty PCOS (by NIH, 1990 criteria) and 60 control (age, race and BMI-matched) women were prospectively studied for body composition (by bioelectrical impedance analysis [BIA]) and basal IR and insulin secretion by the homeostasis model assessment (HOMA-IR and HOMA-%β-cell function, respectively) in a tertiary care academic referral center. A subset of 12 PCOS and 12 matched control women also underwent a modified frequently sampled intravenous glucose tolerance test (FSIVGTT) to determine glucose uptake and insulin secretion in dynamic state. Our results indicate that women with PCOS demonstrated greater degrees of hyperandrogenism, and higher waist-to-hip ratio (WHR), %body fat, fat BMI, F/L, fasting insulin levels, and HOMA-IR and HOMA-%β-cell values, than controls. In models adjusted for WHR and free testosterone and diagnostic groups, fasting insulin levels, HOMA-IR, and

    The aim of the study was to compare the weight gain during pregnancy (using Institute of Medicine guidelines) among Asian Indians across different body mass index (BMI) categories (using World Health Organization Asia Pacific BMI cut points) and to compare the pregnancy outcomes in each of the different BMI categories. Retrospective records of 2728 pregnant women attending antenatal clinics and private maternity centers in Chennai, South India, from January 2011 to January 2014 were studied. Pregnancy outcomes were analyzed in relation to BMI and weight gain across different BMI categories. Overweight and obese women who gained more weight during pregnancy were at high risk of delivering macrosomic infants (overweight - odds ratio [OR]: 2.3, 95% confidence interval [CI]: 1.1-5.2, P = 0.02 and obese - OR: 1.6, 95% CI: 1.1-2.4, P = 0.01). In addition, obese women who gained more weight were also at high risk of preterm labor (OR: 2.1, 95% CI: 1.1-3.8; P = 0.01), cesarean section (OR: 1.9, 95% CI: 1.4-2.5; P women who gained less weight had a protective effect from cesarean section and macrosomia. Overweight/obese women who gained more weight than recommended are at a high risk of developing adverse pregnancy outcomes. Normal and overweight women who gained weight less than recommended have low risk for cesarean section and macrosomia. However, they have a higher (statistically insignificant) risk for low birth weight and preterm birth. This highlights the need for gaining adequate weight during pregnancy.

    Full Text Available This study aimed to assess whether physical intimate partner violence affects the nutritional status of adult women with different levels of body mass index (BMI. This was a population-based cross-sectional study with 625 women selected through complex multistage cluster sampling. Information on physical intimate partner violence was obtained with the Revised Conflict Tactics Scales, and nutritional status was measured as BMI (kg/m2. A quantile regression model was used to assess the effect of physical intimate partner violence at all percentiles of BMI distribution. Physical intimate partner violence occurred in 27.6% of the women (95%CI: 20.0; 35.2. Mean BMI was 27.9kg/m2 (95%CI: 27.1; 28.7. The results showed that physical intimate partner violence was negatively associated with BMI between the 25th and 85th percentiles, corresponding to 22.9 and 31.2kg/m2. The findings support previous studies indicating that physical intimate partner violence can reduce BMI in low-income women.

    Full Text Available Maintenance of reproductive health of women with excessive weight is the actual problem of nowadays and is an important direction of modern medicine. Aim. To analyze the efficiency and acceptability of oral, іntravaginal and transdermal hormonal contraceptives among women with excessive body mass. Methods and results. The tolerability and ease of use of different types of hormonal contraception have been studied in 72 women with excessive body mass to determine the reliability and acceptability of modern hormonal contraceptives. It has been investigated that the effectiveness of hormonal contraceptives according to our data is 100%, none patient was registered with an unwanted pregnancy. The total subjective evaluation of all hormonal contraceptives use were positive: 78.6% of women with excessive body mass who used oral contraceptives, were satisfied with the chosen contraceptive method, 81,8% – were satisfied with intravaginal method, 59,1% – transdermal contraceptive. Conclusions. It has been found that intravaginal contraceptive is most suitable as the drug of first choice for women with overweight compared with oral and transdermal hormonal methods of contraception. This suggests that women with excessive body mass can successfully use modern methods of hormonal contraception. But it is necessary to carry out clinical supervision, during which further clarification on the use of hormonal contraception in women with excessive body mass is possible.

    Fat-free mass (FFM) reduction and the tendency for a reduction in surrounding fatty issue and increase in the middle are a natural consequence of growing old and should be studied in order to gain a better understanding of the aging process. This study set out to find the FFM differences between active elderly women in two age groups (60-69 and 70-80 years) and to determine which of the anthropometric measurements, body weight (BW), abdominal circumference (AC), or body mass index (BMI) are the best predictors of FFM variation within the group. Eighty-one (n=81) active elderly women of the Third Age willingly signed up to participate in the research during the activities at the University of the Third Age (UTA) in Brazil. The research was approved by the Research Ethics Committee of the Faculty of Medical Sciences of the State University of Campinas (UNICAMP). Body weight (BW), height (H) and the BMI were measured according to the international standards. The AC was measured in centimetres at the H of the navel and body composition was ascertained using bioimpedance analysis. The SAS program was used to perform the statistical analysis of independent samples and parametric data. The results showed FFM values with significant differences between the two groups, with the lowest values occurring among the women who were over 70 years of age. In the analysis, the Pearson's Correlation Coefficient for each measured independent variable was ascertained, with the BW measurement showing the highest ratio (0.900). The BW measurement was regarded as reliable, low-cost and easy to use for monitoring FFM in elderly women who engage in physical activities. Copyright © 2011 Elsevier Ireland Ltd.

    Larger body size is associated with greater survival in maintenance hemodialysis (MHD) patients. It is not clear how lean body mass (LBM) and fat mass (FM) compare in their associations with survival across sex in these patients. We examined the hypothesis that higher FM and LBM are associated with greater survival in MHD patents irrespective of sex. In 742 MHD patients, including 31% African Americans with a mean (± SD) age of 54 ± 15 y, we categorized men (n = 391) and women (n = 351) separately into 4 quartiles of near-infrared interactance-measured LBM and FM. Cox proportional hazards models estimated death hazard ratios (HRs) (and 95% CIs), and cubic spline models were used to examine associations with mortality over 5 y (2001-2006). After adjustment for case-mix and inflammatory markers, the highest quartiles of FM and LBM were associated with greater survival in women: HRs of 0.38 (95% CI: 0.20, 0.71) and 0.34 (95% CI: 0.17, 0.67), respectively (reference: first quartile). In men, the highest quartiles of FM and percentage FM (FM%) but not of LBM were associated with greater survival: HRs of 0.51 (95% CI: 0.27, 0.96), 0.45 (95% CI: 0.23, 0.88), and 1.17 (95% CI: 0.60, 2.27), respectively. Cubic spline analyses showed greater survival with higher FM% and higher "FM minus LBM percentiles" in both sexes, whereas a higher LBM was protective in women. In MHD patients, higher FM in both sexes and higher LBM in women appear to be protective. The survival advantage of FM appears to be superior to that of LBM. Clinical trials to examine the outcomes of interventions that modify body composition in MHD patients are indicated.

    An increased release of free fatty acids (FFA) into plasma likely contributes to the metabolic complications associated with obesity. However, the relationship between body fat and FFA metabolism is unclear because of conflicting results from different studies. The goal of our study was to determine the interrelationships between body fat, sex and plasma FFA kinetics. We determined FFA rate of appearance (Ra) in plasma, by using stable isotopically labeled tracer techniques, during basal conditions in 106 lean, overweight, and obese, non-diabetic subjects (43 men and 63 women who had 7.0–56.0 % body fat). Correlation analyses demonstrated: 1) no differences between men and women in the relationship between fat mass and total FFA Ra (µmol·min−1); 2) total FFA Ra increased linearly with increasing FM (r=0.652, Pfashion with increasing FM (r=−0.806; P<0.001); 4) FFA Ra in relationship to fat-free mass was greater in obese than lean subjects and greater in women than in men; 5) abdominal fat itself was not an important determinant of total FFA Ra. We conclude that total body fat, not regional fat distribution or sex, is an important modulator of the rate of FFA release into plasma. Although increased adiposity is associated with a decrease in fatty acid release in relationship to FM, this downregulation is unable to completely compensate for the increase in FM, so total FFA Ra and FFA Ra with respect to FFM are greater in women than in men and in obese than in lean subjects.

    This study compared the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) for 16 weeks on whole-body and abdominal fat mass (FM) in postmenopausal women with type 2 diabetes (T2D). Seventeen women (69±1 years; BMI: 31±1kg.m -2 ) were randomly assigned to either a HIIT [60×(8s at 77-85% HR max , 12s of active recovery)] or MICT (40min at 55-60% of their individual HRR) cycling program for 16 weeks, 2 days/week. Dual-energy X-ray absorptiometry was used to measure whole-body and regional FM content, including abdominal adiposity and visceral adipose tissue. Plasma cholesterol, HDL, LDL, triglycerides, glucose and HbA 1c levels were measured. Levels of nutritional intake and physical activity were evaluated by 7-day self-reports. Dietary energy (caloric) intake, physical activity level and total body mass did not vary in either group from the beginning to the end of the training intervention. Overall, total FM decreased and total fat-free mass significantly increased over time (by around 2-3%). Total FM reduction at the end of the intervention was not significantly different between groups. However, significant loss of total abdominal (-8.3±2.2%) and visceral (-24.2±7.7%) FM was observed only with HIIT. Time effects were noted for HbA 1c and total cholesterol/HDL ratio. With no concomitant caloric restriction, an HIIT program in postmenopausal women with T2D (twice a week for 16 weeks) appeared to be more effective for reducing central obesity than MICT, and could be proposed as an alternative exercise training program for this population.

  14. A critical exploration of science doctoral programs: Counterstories from underrepresented women of color

    Science.gov (United States)

    Bancroft, Senetta F.

    Most studies exploring the experiences of underrepresented doctoral students of color in science fields focus on their socialization into predominantly white institutions. While the socialization process is fundamental to doctoral success and consequently deserves attention, it is critical to inquire into how the widespread and lasting perception of people of color as socioculturally deficient shapes underrepresented students` socialization into science doctoral programs. Further, the existing research literature and educational policies addressing the persistent underrepresentation of students of color in science doctorates remain fixated on increasing racial diversity for U.S. economic security rather than racial equity. In view of the limitation of existing research literature, in this study, drawing from critical race theories, fictive-kinship, and forms of capital, I use counterstorytelling to recast racial inequities in the education of science doctorates as a problem of social justice, not as an issue of the students' sociocultural deficits or as a matter of economic security. Through interviews I examined the experiences, from elementary school to current careers, of three women of color who were science doctoral students. Participants' counterstories revealed institutionalized racism embedded in doctoral programs exploited their identities and dismissed their lived experiences, thereby, relegating them to outsiders-within academe. This marginalization precluded the inclusive socialization of participants into their doctoral programs and ultimately set up barriers to their pursuit of scientific careers. This study divulges the academic and career consequences of the sustained privilege disparities between underrepresented students of color's experience and the experiences of their white and Asian counterparts. In light of the participants' experiences, I recommend that, in order to change the existing policy of socially integrating students into oppressive

    Conflicting associations between total homocysteine (tHcy), body mass index (BMI) lean body mass, and fat mass in the general population have been reported. We investigated the hypothesis that elevated tHcy levels are associated with increased BMI, waist-to-hip ratio (WHR), and body fat mass percent. In Jordan, obesity and overweight are prevalent among reproductive women and hyperhomocysteinemia, along with obesity and overweight, are independent risk factors for cardiovascular diseases. The participants used in this cross-sectional study were 325 overweight Jordanian women aged between 18 and 49 years old. The main outcome measures were tHcy, BMI, WHR, fat mass, fat-free mass, and total body water. Serum tHcy was analyzed using a liquid chromatography tandem mass spectrophotometry (LC-MS/MS) complete kit. The body compositions were measured using a bioelectrical impedance analyzer. Study participants were stratified according to their tHcy level into two groups, ≤10 μmol/L and >10 μmol/L, and the difference between mean values of body compositions was evaluated. The tHcy was significantly and negatively correlated with age, fat-free mass, and total body water, and significantly and positively correlated with BMI, hip circumference, WHR, fat mass, and dry lean weight. The chi-square and the independent sample t-tests showed statistically significant (P ≤ .05) differences between tHcy and BMI, WHR, fat and fat-free mass, and total body water percentages. In conclusion, BMI, WHR and body fat mass were found to be associated with elevated tHcy levels among overweight reproductive women, and they might be used as independent predictors of the tHcy level.

    Full Text Available Digital storytelling is as an arts-based research method that offers researchers an opportunity to engage deeply with participants, speak back to dominant discourses, and re-imagine bodily possibilities. In this article, we describe the process of developing a research-based digital storytelling curriculum exploring eating disorder recovery. We have built this curriculum around research interviews with young women in recovery as well as research and popular literature on eating disorder recovery. Here, we highlight how the curriculum acted as a scaffolding device for the participants' artistic creation around their lived experiences of recovery. The participants' stories crystallize what resonated for them in the workshop process: they each have an open-ended narrative arc, emphasize the intercorporeality of recovery, and focus on recovery as process. The nuances within each story reveal unique embodied experiences that contextualize their recoveries. Using the example of eating disorder recovery, we offer an illustration of the possibilities of digital storytelling as a critical arts-based research method and what we gain from doing research differently in terms of participant-researcher relationships and the value of the arts in disrupting dominant discourses.

    Full Text Available Context: Nutrition plays a vital role in the quality of life in postmenopausal women. Aim: The aim is to determine the dietary intake, physical activity, and assess the body mass index (BMI among postmenopausal women. Settings and Design: A community-based sample survey. Materials and Methods: The present study included 140 postmenopausal women (40–70 years from Udupi, Manipal areas of Karnataka. The study was carried out between July and December 2013. Sociodemographic data were collected using a questionnaire. Anthropometric data included height, weight, waist, and hip circumference. Dietary intake was determined using 24 h dietary recall. Physical activity information was collected. Statistical Analysis Used: Data were analyzed using SPSS version 16 software. Paired t-test was performed to determine the dietary adequacy. Results: Obesity was 42.1% among the study participants. Increased WHR and waist circumference were 82.1% and 77.1%. Mean daily intake of calcium and saturated fatty acids were significantly higher than recommended dietary allowance (RDA (P < 0.001. Mean intake of energy, protein, carbohydrate, mono and poly unsaturated fatty acid, fiber and sodium were significantly lower than RDA (P < 0.001. Average daily intake of cereals, pulses, roots and tubers, meat and products, fats and oils, green leafy, and other vegetables were significantly (P < 0.001 lower than RDA. Intake of fruits, milk and milk products, and sugar was significantly higher (P < 0.001 than RDA. Only 37.1% of women performed moderate or active exercises regularly. Conclusions: Even though, nutrient and food group deficiencies were observed among postmenopausal women physical inactivity and effects of menopausal transition instigate increased BMI imposing a need to educate on nutrition and physical activity.

    Full Text Available Obesity is one of the most important problems of modern societies, and is considered a modern plague which tends to evolve to a global pandemic. Premenopausal women, most of the times, manifest hormonal dysfunctions and dysfunctions in their metabolism. The consequences are weight gain, heart diseases, hypertension and diabetes mellitus type 2. Purpose: The purpose of this study was to examine if vitamin D levels and Glycosylated hemoglobin are affected by exercise and if there is a connection between Body Mass Index (BMI and insulin. Method: The research involved 48 healthy premenopausal women who answered questionnaires which included questions about their height, weight, waist circumference, lifestyle and history of menstruation. This questionnaire, after due electronic approval, was based on a model of the German Sports and Research Centre (Karlsruhe Institut Fuer Sport und Sportwissenschaft. Women, after having completed a consent form, were also subjected to laboratory testing to determine their insulin, vitamin D levels and Glycosylated hemoglobin levels. To specify the vitamin D and insulin levels a method of direct chemiluminescence was used, and Glycosylated hemoglobin identification was specified using an automated light metering method. Statistical analysis performed using ΙΒΜ SPSS 22. Results: At the premenopausal women (41+/-7ετών (BMI24+/-4 kg/m2 a significant impact during the time of the exercises in the glycosylated hemoglobin (p = 0.038 0.05 regarding the levels of Glycosylated hemoglobin and the combination of exercise with other physical activities. Finally, a significant correlation between BMI and insulin (p=0.001<0.05 was detected. Furthermore, there was no statistically significant difference found in vitamin D levels relative to physical activity. Conclusion: During the research it was found that BMI influences the secretion of insulin, and insulin resistance that is a metabolism disorder, is a result of

    Nutrition in pregnancy has implications for both mother and fetus, hence the importance of an accurate assessment at the booking visit during antenatal care. The body mass index (BMI, kg/m2) is currently the gold standard for measuring body fatness. However, pregnancy-associated weight gain and oedema, as well as late booking in our population setting, cause concern about the reliability of using the BMI to assess body fat or nutritional status in pregnancy. The mid-upper arm circumference (MUAC) has been used for many decades to assess malnutrition in children aged <5 years. Several studies have also shown a strong correlation between MUAC and BMI in both pregnant and non-pregnant adult populations. To assess the correlation between the MUAC and BMI in pregnant women booking for antenatal care in the Metro West area of Cape Town, South Africa. We conducted a cross-sectional study of women booking at four midwife obstetric units. Anthropometric measurements (height, weight and MUAC) were carried out on pregnant women at their first antenatal booking visit. The results showed a strong correlation between MUAC and BMI in pregnant women up to 30 weeks' gestation. The correlation was calculated at 0.92 for the entire group. The MUAC cut-offs for obesity (BMI >30) and malnutrition (BMI <18.5) were calculated as 30.57 cm and 22.8 cm, respectively. MUAC correlates strongly with BMI in pregnancy up to a gestation of 30 weeks in women attending Metro West maternity services. In low-resource settings, the simpler MUAC measurement could reliably be substituted for BMI to assess nutritional status.

    To describe the prevalence of Vitamin D deficiency (VDD) and insufficiency (VDI), and the main dietary sources of vitamin D (VD) in a probabilistic sample of Mexican women at reproductive age participating in Ensanut 2012, stratified by sociodemographic factors and body mass index (BMI) categories. Serum concentrations of 25-hydroxyvitamin-D(25-OH-D) were determined using an ELISA technique in 4162 women participants of Ensanut 2012 and classified as VDD, VDI or optimal VD status. Sociodemographic, anthropometric and dietary data were also collected. The association between VDD/VDI and sociodemographic and anthropometry factors was assessed adjusting for potential confounders through an estimation of a multinomial logistic regression model. The prevalence of VDD was 36.8%, and that of VDI was 49.8%. The mean dietary intake of VD was 2.56 μg/d. The relative risk ratio (RRR) of VDD or VDI was calculated by a multinomial logistic regression model in 4162 women. The RRR of VDD or VDI were significantly higher in women with overweight (RRR: 1.85 and 1.44, p<0.05), obesity (RRR: 2.94 and 1.93, p<0.001), urban dwelling (RRR:1.68 and 1.31, p<0.06), belonging to the 3rd tertile of income (RRR: 5.32 and 2.22, p<0.001), or of indigenous ethnicity (RRR: 2.86 and 1.70, p<0.05), respectively. The high prevalence of VDD/VDI in Mexican women calls for stronger actions from the health authorities, strengthtening the actual policy of food supplementation and recommending a reasonable amount of sun exposure.

    Periodontitis and overweight/obesity prevalence are both increasing worldwide. Overweight/obesity has been suggested as a risk factor for developing periodontitis. The aim of this study was to determine the association between obesity and periodontitis among postmenopausal Jordanian women. Cross-sectional associations between obesity and periodontitis were examined in 400 postmenopausal women aged 50-79 years. All women completed a questionnaire, had a clinical periodontal examination and had their weight and height recorded. Multivariable analysis was carried out using logistic regression with adjustment for possible confounders. Based on body mass index (BMI), 23.5% of the women were considered overweight and 70% were obese. Obese participants with BMI≥25 had decreased odds (OR) for having periodontitis compared to participants with normal weight (OR: 0.54; 95% confidence interval [CI]: 0.27-0.87). The obese patients showed significantly higher loss of clinical attachment (CAL), calculus, as well as plaque and gingival index and as compared to normal and overweight (pobese women as measured by average percent of sites with the deepest CAL≥5 mm (p=0.025). There was no significant difference in mean and percentage of sites with alveolar crestal bone loss (ACH) among different categories of obesity. In conclusion, BMI may be inversely associated with prevalence of periodontitis but positively related to the severity of periodontitis assessed by several periodontal parameters such as CAL, recession, plaque, and calculus. Additional prospective studies to further quantify, or understand the mechanisms, of this association are merited. Copyright © 2015 Asia Oceania Association for the Study of Obesity.

    The objective was to evaluate the relationship between the gender hormonal levels and bone mineral density in premenopausal women suffering with sickle cell disease. Method was a cross-sectional study including consecutive female adult patients with sickle cell anemia attending the outpatient hematology/orthopedic clinics, or admitted to King Fahd University Hospital, Al-Khobar, Saudi Arabia, between August 2006 and June 2007. Patient's age was documented and body mass index was calculated. Blood was drawn for complete blood picture, biochemistry and hormonal profile including total estradiol E2 and total testosterone Te. Bone mineral density BMD was measured for all patients using dual energy x-ray absorptiometry scan at the hip and lumbar spine. We analyzed the data of 51 patients with an average age of 26+/-3.1 years. Patients were divided into two groups group A and group B. Group A had normal BMD and group B with low BMD. Thirty-one (60.8%) were in group A and 20 (39.2%) were in group B. The E-2 level was not statistically different between the 2 groups, while Te level was significantly lower in women with low BMD 38+/-11.8 versus 22.3+/-11.7 ng/dl, p<0.001. Our study indicates that in menopausal female patients with sickle cell anemia, testosterone may play a role in the preservation of bone mass. (author)

    Full Text Available ObjectiveEstradiol (E2 regulates adipose tissue resulting in increased fat mass (FM with declining E2. However, increased visceral fat and hyperestrogenemia are features of obese individuals. It is possible that adipocytes in obese individuals are less sensitive to E2 resulting in higher FM. Our objective is to identify the range of serum E2 for which postmenopausal women have the lowest FM and best body composition.MethodsCross-sectional data from 252 community-dwelling postmenopausal women, 42–90 years old.

While fat-free mass (FFM, kg increased with increasing E2 (p < 0.001, % FFM was highest in group 3.ConclusionIn our population of postmenopausal women, FM followed a U-shaped distribution according to E2 levels. E2 between 14.0 and 17.4 pg/ml is associated with the best body composition, i.e., lowest total and % FM and highest % FFM. Given the role of E2 in regulating body fat, high FM at the high end of the E2 spectrum may suggest reduced E2 sensitivity in adipocytes among obese postmenopausal women.Clinical TrialsClinicalTrials.gov identifier: NCT00146107.

    Full Text Available Spectral properties for the two-dimensional quantum S=1 XY model were investigated with the exact diagonalization method. In the symmetry-broken phase, there appear the massive Higgs and massless Goldstone excitations, which correspond to the longitudinal and transverse modes of the spontaneous magnetic moment, respectively. The former excitation branch is embedded in the continuum of the latter, and little attention has been paid to the details, particularly, in proximity to the critical point. The finite-size-scaling behavior is improved by extending the interaction parameters. An analysis of the critical amplitude ratio for these mass gaps is made.

    The environmental estrogen, zearalenone (ZEA), is found in the food supply from Fusarium fungal contamination in grains and sometimes used as a growth promoter for beef cattle. Long-term exposure to ZEA and its metabolites may present health risk due to higher estrogenic activity. Serum ZEA metabolites were measured to determine the exposure and the association with food intake in 48 overweight/obese women (52 ± 9 years). The free and conjugated ZEA indicated the highest detection rate of all the metabolites. Conjugated ZEA and total ZEA metabolites were lower (p = 0.02) in overweight/obese than normal weight women, and free metabolites were either the same or showed a trend to be higher. In addition, those with highest (280-480 g/d) compared those with lowest (metabolite concentrations (p metabolites. These findings indicate that ZEA and its metabolites are detectable in nearly all women and concentrations are associated with greater meat intake, and influenced by body mass index. Determining how the food supply influences human concentrations of ZEA metabolites is warranted, as well as determining vulnerable populations. Copyright © 2018. Published by Elsevier Ltd.

    Insulin resistance is a common feature among women with polycystic ovary syndrome (PCOS), especially in those patients with hyperandrogenism and chronic anovulation. PCOS women are at risk for developing metabolic syndrome, impaired glucose tolerance and type II diabetes mellitus (DM II). The aim of this review is to explore the existing knowledge of the interplay between androgen excess, pancreatic β-cell function, non-alcoholic fatty liver disease (NAFLD), intra-abdominal and subcutaneous (SC) abdominal adipocytes in PCOS, providing a better comprehension of the molecular mechanisms of diabetologic interest. A comprehensive MEDLINE ® search was performed using relevant key terms for PCOS and DM II. Insulin-induced hyperandrogenism could impair pancreatic β-cell function, the SC abdominal adipocytes' lipid storage capacity, leading to intra-abdominal adipocyte hypertrophy and lipotoxicity, which in turn promotes insulin resistance, and could enhance NAFLD. Fetal hyperandrogenism exposure prompts to metabolic disorders. Treatment with flutamide showed to partially reverse insulin resistance. Metabolic impairment seems not to be dependent only on the total fat mass content and body weight in women with PCOS and might be ascribed to the androgen excess.

    Conclusions: Measurements of physical function can effectively identify elderly women with low bone mass at an early stage without the need for bone mass measurements. In particular, one-leg standing time and 10-m gait time were good predictors of low bone mass, and is easy to measure, low-cost, and can be self-measured. These findings will be helpful in the prevention and treatment of osteoporosis.

    Full Text Available Abstract Background While risk factors of osteoporosis in Western populations have been extensively documented, such a profile has not been well studied in Caucasians of non-European origin. This study was designed to estimate the modifiable distribution and determinants of bone mineral density (BMD among Iranian women in Australia. Methods Ninety women aged 35 years and older completed a questionnaire on socio-demographic and lifestyle factors. BMD was measured at the lumbar spine (LS and femoral neck (FN using DXA (GE Lunar, WI, USA, and was expressed in g/cm2 as well as T-score. Results In multiple regression analysis, advancing age, lower body mass index (BMI, and smoking were independently associated with LS and FN BMD, with the 3 factors collectively accounting for 30% and 38% variance of LS and FN BMD, respectively. LS and FN BMD in smokers was 8% lower than that in non-smokers. Further analysis of interaction between BMI and smoking revealed that the effect of smoking was only observed in the obese group (p = 0.029 for LSBMD and p = 0.007 for FNBMD, but not in the overweight and normal groups. Using T-scores from two bone sites the prevalence of osteoporosis (T-scores ≤ -2.5 was 3.8% and 26.3% in pre-and post-menopausal women, respectively. Among current smokers, the prevalence was higher (31.3% than that among ex-smokers (28.6% and non-smokers (7.5%. Conclusion These data, for the first time, indicate that apart from advancing age and lower body mass index, cigarette smoking is an important modifiable determinant of bone mineral density in these Caucasians of non-European origin.

    Osteoporosis is a disease associated with insulin resistant states such as central obesity, diabetes, and metabolic syndrome. Non-alcoholic fatty liver disease (NAFLD) is also increased in such conditions. However, little is known about whether osteoporosis and nonalcoholic fatty liver disease are etiologically related to each other or not. We examined whether bone mineral density (BMD) is associated with NAFLD in pre- and postmenopausal women. Four hundred eighty-one female subjects (216 premenopausal and 265 postmenopausal) were enrolled. Lumbar BMD was measured using dual-energy X-ray absorptiometry. Liver ultrasonography was done to check the severity of fatty liver. We excluded subjects with a secondary cause of liver disease. Blood pressure, lipid profile, fasting plasma glucose, alanine aminotransferase (ALT), aspartate aminotransferase, and body mass index were measured in every subject. Mean lumbar BMD was lower in subjects with NAFLD than those without NAFLD in postmenopausal women (0.98 ± 0.01 vs. 1.01 ± 0.02 g/cm², P = 0.046). Multiple correlation analysis revealed a significant association between mean lumbar BMD and NAFLD in postmenopausal subjects after adjusting for age, body mass index, ALT, smoking status, and alcohol consumption (β coefficient -0.066, 95% CI -0.105 to -0.027, P = 0.001). Even after adjusting the presence of metabolic syndrome, the significance was maintained (β coefficient -0.043, 95% CI -0.082 to -0.004, P = 0.031). Lumbar BMD is related with NAFLD in postmenopausal females. We suggest that postmenopausal women with NAFLD may have a higher risk of osteoporosis than those without.

    Since the publication of the 1975 Mass Predictions approximately 300 new atomic masses have been reported. These data come from a variety of experimental studies using diverse techniques and they span a mass range from the lightest isotopes to the very heaviest. It is instructive to compare these data with the 1975 predictions and several others (Moeller and Nix, Monahan, Serduke, Uno and Yamada which appeared latter. Extensive numerical and graphical analyses have been performed to examine the quality of the mass predictions from the various models and to identify features in these models that require correction. In general, there is only rough correlation between the ability of a particular model to reproduce the measured mass surface which had been used to refine its adjustable parameters and that model's ability to predict correctly the new masses. For some models distinct systematic features appear when the new mass data are plotted as functions of relevant physical variables. Global intercomparisons of all the models are made first, followed by several examples of types of analysis performed with individual mass models

    Full Text Available We investigated the effect of exercise training on body composition change in women. Nineteen Mexican-American and 18 Korean premenopausal overweight/obese women were randomized into one of the following groups: control, low-intensity training group (LI, and high-intensity training group (HI. Subjects completed 12 weeks of training at 50–56% maximal oxygen consumption (LI or 65–70% maximal oxygen consumption (HI. Body composition components were measured at baseline and after training using dual-energy X-ray absorptiometry for Mexican-Americans, while whole-body composition was measured by the direct segmental multifrequency bioelectrical impedance analysis and abdominal fat was measured by single-slice computed tomography for Koreans. Data were analyzed using mixed-model repeated measures independent of age, ethnicity, and body mass index (BMI. Exercise training showed a significant effect on BMI, fat percentage, fat mass, lean mass, and visceral adipose tissue area. HI significantly decreased fat mass and fat percentage but increased lean mass (all P<0.05. LI significantly reduced BMI, fat mass, fat percentage, and visceral adipose tissue area but increased lean mass (all P<0.05. Exercise training had a beneficial effect on reducing BMI, fat percentage, fat mass, and visceral adipose tissue area but had no effect on increasing lean mass for Mexican-American and Korean premenopausal overweight/obese women.

    The increasing prevalence of overweight and obesity is a critical public health problem for women. The negative effect of stress on memory and cognitive functions has been widely explored for decades in numerous research projects using a wide range of methodology. Deterioration of memory and other brain functions is a hallmark of Alzheimer's disease. Estrogen fluctuations and withdrawal have myriad direct effects on the central nervous system that have the potential to influence cognitive functions. The present study aims to compare the effect of stress on the cognitive functions in overweight/obese women before and after menopause. A total of 142 female subjects constituting women before menopause between the ages of 18 and 44 years and women after menopause between the ages of 45 and 60 years were included in the sample. Participants were categorized into overweight/obese groups based on the body mass index. The major tool perceived stress scale was used for measuring the perception of stress. On the basis of the stress scale measurement, each group was classified into with stress and without stress. Addenbrooke's Cognitive Examination-III was used for measuring the cognitive functions. Premenopausal women with stress showed a significant (pembroidery, games and relaxation techniques should be recommended to prevent stress. Insights into the neurobiology before and after menopause can be gained from future studies examining the effect on the hypothalamic-pituitary-adrenal axis in relation to cognition and stress.

    Polycystic ovary syndrome (PCOS) puts patients at higher risk for obesity and diabetes. Poor health literacy is also associated with these conditions. Notably, weight loss is associated with improved ovulation and pregnancy rates for women with PCOS. In this study the association between health literacy and body mass index (BMI) among women with PCOS was examined. The health literacy of women with PCOS was measured using the Arabic version of the single item literacy screener (SILS) at a university medical center. Sociodemographic and medical information was collected by interviewing the participants and reviewing their medical records, respectively. The relationship between health literacy and BMI was assessed by multiple logistic regression analysis. Health literacy was assessed in 127 women with PCOS from September 2015 to February 2016. Only 16.54% of participants had limited health literacy. The mean BMI for all participants was 30.57 (kg/m 2 ), and the mean age was 27.40 years. Further, most of the participants (74%) had a high school diploma or a higher degree. Almost 56% of the participants were taking metformin, and 11.81% had hypothyroidism. After controlling for age, education, hypothyroidism diagnosis, and the use of metformin, participants with high BMI were 10% less likely to have a good health literacy level (OR = 0.904; 95% CI = 0.829-0.987; P  = 0.0238). Improving the health literacy of patients with PCOS may have a positive impact on their BMI and eventually lead to favorable health outcomes.

    Action to improve women's occupational health has been slowed by a notion that women's jobs are safe and that any health problems identified among women workers can be attributed to unfitness for the job or unnecessary complaining. With increasing numbers of women in the labor force, the effects of work on women's health have recently started to interest health care providers, health and safety representatives and researchers. We begin our summary of their discoveries with a discussion of women's place in the workplace and its implications for occupational health, followed by a brief review of some gender-insensitive data-gathering techniques. We have then chosen to concentrate on the following four areas: methods and data collection; directing attention to women's occupational health problems; musculoskeletal disease; mental and emotional stress. We conclude by pointing out some neglected occupational groups and health issues.

    Full Text Available Introduction: Age-related changes in muscle mass and muscle tissue composition contribute to diminished strength in older adults. The objectives of this study are to examine if an assessment method using mobile diagnostic ultrasound augments well-known determinants of lean body mass (LBM to aid sarcopenia staging, and if a sonographic measure of muscle quality is associated with muscle performance.Methods: Twenty community-dwelling female subjects participated in the study (age = 43.4 ±20.9 years; BMI: 23.8, interquartile range: 8.5. Dual energy X-ray absorptiometry (DXA and diagnostic ultrasound morphometry were used to estimate LBM. Muscle tissue quality was estimated via the echogenicity using grayscale histogram analysis. Peak force was measured with grip dynamometry and scaled for body size. Bivariate and multiple regression analyses were used to determine the association of the predictor variables with appendicular lean mass (aLM/ht2, and examine the relationship between scaled peak force values and muscle echogenicity. The sarcopenia LBM cut point value of 6.75 kg/m2 determined participant assignment into the Normal LBM and Low LBM subgroups.Results: The selected LBM predictor variables were body mass index (BMI, ultrasound morphometry, and age. Although BMI exhibited a significant positive relationship with aLM/ht2 (adj. R2 = .61, p < .001, the strength of association improved with the addition of ultrasound morphometry and age as predictor variables (adj. R2 = .85, p < .001. Scaled peak force was associated with age and echogenicity (adj. R2 = .53, p < .001, but not LBM. The Low LBM subgroup of women (n = 10 had higher scaled peak force, lower BMI, and lower echogenicity values in comparison to the Normal LBM subgroup (n = 10; p < .05.Conclusions: Diagnostic ultrasound morphometry values are associated with LBM, and improve the BMI predictive model for aLM/ht2 in women. In addition, ultrasound proxy measures of muscle quality are more

    Criticality dimensions for highly enriched 235 U (93.5) and 239 Pu (95.5) systems mixed with D 2 O were studied. The objective of this work is to investigate the minimum critical mass and concentration of uranium and plutonium systems in a reflector-moderated arrangement. The present work demonstrates the critical instability of some of these systems that are reflected by D 2 O and expands from previously published and unpublished work. These calculations were performed in a spherical geometry with the DANTSYS codes using the Hansen-Roach cross-section library. Densities examined ranged from normal to very small and are assumed to be uniform throughout the core. These spherical systems are reflected by 100 cm of D 2 O

  20. Later abortions and mental health: psychological experiences of women having later abortions--a critical review of research.

    2011-01-01

    Some abortion policies in the U.S. are based on the notion that abortion harms women's mental health. The American Psychological Association (APA) Task Force on Abortion and Mental Health concluded that first-trimester abortions do not harm women's mental health. However, the APA task force does not make conclusions regarding later abortions (second trimester or beyond) and mental health. This paper critically evaluates studies on later abortion and mental health in order to inform both policy and practice. Using guidelines outlined by Steinberg and Russo (2009), post 1989 quantitative studies on later abortion and mental health were evaluated on the following qualities: 1) composition of comparison groups, 2) how prior mental health was assessed, and 3) whether common risk factors were controlled for in analyses if a significant relationship between abortion and mental health was found. Studies were evaluated with respect to the claim that later abortions harm women's mental health. Eleven quantitative studies that compared the mental health of women having later abortions (for reasons of fetal anomaly) with other groups were evaluated. Findings differed depending on the comparison group. No studies considered the role of prepregnancy mental health, and one study considered whether factors common among women having later abortions and mental health problems drove the association between later abortion and mental health. Policies based on the notion that later abortions (because of fetal anomaly) harm women's mental health are unwarranted. Because research suggests that most women who have later abortions do so for reasons other than fetal anomaly, future investigations should examine women's psychological experiences around later abortions.

    This manuscript evaluates whether specific symptoms, a symptom index (SI), CA125 and HE4 can help identify women with malignant tumors in the group of women with adnexal masses previously diagnosed with ultrasound. This was a cross-sectional study with data collection between January 2010 and January 2012. We invited 176 women with adnexal masses of suspected ovarian origin, attending the hospital of the Department of Obstetrics and Gynecology of the Unicamp School of Medicine. A control group of 150 healthy women was also enrolled. Symptoms were assessed with a questionnaire tested previously. Women with adnexal masses were interviewed before surgery to avoid recall bias. The Ward Agglomerative Method was used to define symptom clusters. Serum measurements of CA125 and HE4 were made. The Risk of Ovarian Malignancy Algorithm (ROMA) was calculated using standard formulae. Sixty women had ovarian cancer and 116 benign ovarian tumors. Six symptom clusters were formed and three specific symptoms (back pain, leg swelling and able to feel abdominal mass) did not agglomerate. A symptom index (SI) using clusters abdomen, pain and eating was formed. The sensitivity of the SI in discriminating women with malignant from those with benign ovarian tumors was 78.3%, with a specificity of 60.3%. Positive SI was more frequent in women with malignant than in women with benign tumors (OR 5.5; 95% CI 2.7 to 11.3). Elevated CA125 (OR 11.8; 95% CI 5.6 to 24.6) or HE4 (OR 7.6; 95% CI 3.7 to 15.6) or positive ROMA (OR 9.5; 95% CI 4.4 to 20.3) were found in women with malignant tumors compared with women with benign tumors. The AUC-ROC for CA125 was not different from that for HE4 or ROMA. The best specificity and negative predictive values were obtained using CA125 in women with negative SI. Women diagnosed with an adnexal mass could benefit from a short enquiry about presence, frequency and onset of six symptoms, and CA125 measurements. Primary care physicians can be thereby assisted in

  2. PULSATION-TRIGGERED MASS LOSS FROM AGB STARS: THE 60 DAY CRITICAL PERIOD

    Low- and intermediate-mass stars eject much of their mass during the late, red giant branch (RGB) phase of evolution. The physics of their strong stellar winds is still poorly understood. In the standard model, stellar pulsations extend the atmosphere, allowing a wind to be driven through radiation pressure on condensing dust particles. Here, we investigate the onset of the wind, using nearby RGB stars drawn from the Hipparcos catalog. We find a sharp onset of dust production when the star first reaches a pulsation period of 60 days. This approximately coincides with the point where the star transitions to the first overtone pulsation mode. Models of the spectral energy distributions show stellar mass-loss rate suddenly increasing at this point, by a factor of ∼10 over the existing (chromospherically driven) wind. The dust emission is strongly correlated with both pulsation period and amplitude, indicating stellar pulsation is the main trigger for the strong mass loss, and determines the mass-loss rate. Dust emission does not strongly correlate with stellar luminosity, indicating radiation pressure on dust has little effect on the mass-loss rate. RGB stars do not normally appear to produce dust, whereas dust production by asymptotic giant branch stars appears commonplace, and is probably ubiquitous above the RGB-tip luminosity. We conclude that the strong wind begins with a step change in mass-loss rate and is triggered by stellar pulsations. A second rapid mass-loss-rate enhancement is suggested when the star transitions to the fundamental pulsation mode at a period of ∼300 days.

    Full Text Available Background. Nutrition in pregnancy has implications for both mother and fetus, hence the importance of an accurate assessment at the booking visit during antenatal care. The body mass index (BMI, kg/m2 is currently the gold standard for measuring body fatness. However, pregnancy-associated weight gain and oedema, as well as late booking in our population setting, cause concern about the reliability of using the BMI to assess body fat or nutritional status in pregnancy. The mid-upper arm circumference (MUAC has been used for many decades to assess malnutrition in children aged 30 and malnutrition (BMI <18.5 were calculated as 30.57 cm and 22.8 cm, respectively. Conclusion. MUAC correlates strongly with BMI in pregnancy up to a gestation of 30 weeks in women attending Metro West maternity services. In low-resource settings, the simpler MUAC measurement could reliably be substituted for BMI to assess nutritional status.

    2007-01-01

    In the classical physics we inherited from Isaac Newton, mass does not arise, it simply is. The mass of a classical object is the sum of the masses of its parts. Albert Einstein showed that the mass of a body is a measure of its energy content, inviting us to consider the origins of mass. The protons we accelerate at Fermilab are prime examples of Einsteinian matter: nearly all of their mass arises from stored energy. Missing mass led to the discovery of the noble gases, and a new form of missing mass leads us to the notion of dark matter. Starting with a brief guided tour of the meanings of mass, the colloquium will explore the multiple origins of mass. We will see how far we have come toward understanding mass, and survey the issues that guide our research today.

    Optimal gestational weight gain has not yet been clearly defined and remains one of the most controversial issues in modern perinatology. The role of optimal weight gain during pregnancy is critical, as it has a strong effect on perinatal outcomes. In this study, gestational body mass index (BMI) change, accounting for maternal height, was investigated as a new criterion for gestational weight gain determination, in the context of fetal growth assessment. We had focused on underweight women only, and aimed to assess whether the Institute of Medicine (IOM) guidelines could be considered acceptable or additional corrections are required in this subgroup of women. The study included 1205 pre-pregnancy underweight mothers and their neonates. Only mothers with singleton term pregnancies (37th-42nd week of gestation) with pre-gestational BMI gestational age (SGA) infants in the study population was 16.2 %. Our results showed the minimal recommended gestational weight gain of 12-14 kg and BMI change of 4-5 kg/m 2 to be associated with a lower prevalence of SGA newborns. Based on our results, the recommended upper limit of gestational mass change could definitely be substantially higher. Optimal weight gain in underweight women could be estimated in the very beginning of pregnancy as recommended BMI change, but recalculated in kilograms according to body height, which modulates the numerical calculation of BMI. Our proposal presents a further step forward towards individualized approach for each pregnant woman.

  7. Application of the mass-based UNIQUAC model to membrane systems: A critical revision

    2012-01-01

    Highlights: ► UNIQUAC model in mass-based terms is considered for the description of sorption equilibria in membrane systems. ► Model validation of molar and mass-based model is performed on simple (vapor + liquid) equilibrium. ► Discrepancy is found between molar and mass-based model, which is attributed to an incorrect conversion. ► Novel model based on correct thermodynamics is provided for future research. - Abstract: The UNIQUAC model is very suitable in describing (liquid + liquid) as well as (vapor + liquid) equilibrium for a wide range of systems. It can be extended to (solvent + polymer) systems for describing sorption equilibria. The original model is expressed in molar-based terms, but requires knowledge of structural parameters and molar masses of all components. Since these cannot always be easily determined for membranes, a conversion to mass-based terms is often performed, which eliminates this issue. Many studies use this model to calculate sorption equilibria in (solvent + polymer) systems. Nevertheless, in this work the conversion from molar to mass-based parameters is postulated to be erroneous. This even leads to an incorrect description of simple (vapor + liquid) equilibrium of pure liquid mixtures and hence it is advised not to use this model for further modeling of sorption equilibrium in (solvent + polymer) systems. In this paper, the errors in the conversion are pinpointed, and the effects it can have on the description of (vapor + liquid) equilibrium, if used improvident, are demonstrated. Furthermore, it is shown that in fact a simple and straightforward conversion can be performed. Finally, in the case when polymers are involved, an adaption and simplification to the model was successfully applied.

    2011-01-01

    Full Text Available While in contemporary Hungarian literature women authors are constantly emerging and make themselves much more visible than ever before, the gender bias underlying literary evaluations seem to remain nearly intact. In her study Györgyi Horváth discusses three aspects of the gendered regimes of authority in order to give deeper insights into how gender bias re-produces within the Hungarian context. First, she focuses on lists of literary prize winners and critical rankings of published works (showing how many women writers are present on such lists in absolute numbers and in what percentages, and how their numbers have changed over time. Secondly, she explores the practice of critique writing itself, by analyzing the book review pages in two literary journals between 2007 and 2009 focusing on cases when the issue of “gender” itself comes up in the rhetoric of critics trying to underpin their aesthetic judgments on a given work. And finally, she examines briefly the attitude of contemporary women writers towards Gender Studies. Horváth concludes that Gender Studies in Hungary has not contributed significantly to increasing the prestige of contemporary women writers, most of whom, in turn, do not want to be involved with Gender Studies or feminism at all. She also points out that at present in Hungary there is a general blindness in understanding how gender/power relations permeate aesthetic judgments.

    Full Text Available There are a number of disadvantages inherent in all oral hormonal contraceptives: need for daily administration, fluctuations of hormone levels throughout the day, metabolism in the gastrointestinal tract, the effect of the first passage through the liver. All this became a prerequisite to the creation of prolonged oral hormonal methods of contraception, which would be devoid of these shortcomings. One of such method of hormonal contraception is intravaginal hormonal system. The aim was to determine the safety and efficacy of its use in women of reproductive age with overweight. 43 women were included. State of lipid metabolism, changes of the hemostatic system, blood pressure and weight fluctuations in the past 6 months of using intravaginal hormonal contraceptive system were studied. Results. It is established that hormonal intravaginal contraceptive ring gives minimal metabolic effects. Conclusion. This suggests that this ring can be used successfully in patients with excessive body mass, because there is no effect of the ring on hemostasis, lipid metabolism and body weight.

    To determine whether meal size is related to body mass index (BMI) in obese subjects with binge-eating disorder (BED). Five groups of subjects each consumed two laboratory-test meals on nonconsecutive days. Forty-two women, categorized by BMI and BED diagnosis, were instructed to "binge" during one meal and to eat "normally" during another. Eighteen women had BMI values >38 kg/m(2) (more-obese) and 17 had BMI values between 28 to 32 kg/m(2) (less-obese). Twelve of the more-obese and nine of the less-obese individuals met Diagnostic and Statistical Manual (DSM)-IV criteria for BED. Seven normal-weight women also participated as controls. Subjects with BED ate significantly more in both meals than subjects without BED. Binge meals were significantly larger than normal meals only among subjects with BED. The more-obese subjects with BED ate significantly more than the less-obese subjects with BED, but only when they were asked to binge. Intake of the binge meal was significantly, positively correlated with BMI among subjects with BED. Subjects with BED reported significantly higher satiety ratings after the binge than after the normal meal, but subjects without BED reported similar ratings after both meals. Regardless of instructions and diagnosis, obese subjects consumed a significantly higher percentage of energy from fat (38.5%) than did normal-weight subjects (30.8%). During binge meals, the energy intake of subjects with BED is greater than that of individuals of similar body weight without BED and is positively correlated with BMI.

    Full Text Available To assess factors associated with bone mineral density (BMD in postmenopausal women in a longitudinal study, and to examine the relative contribution of lean mass, fat mass, dietary patterns, and years since menopause to BMD.Two hundred and eighty-two postmenopausal women were randomly selected from Hongqi Community Health Center, in Harbin City, China. All participants were followed up from 2009 to 2011. Dietary data were collected using a Food Frequency Questionnaire. BMD of the left hip, the lumbar spine, and the total body, and the body composition were measured by dual-energy X-ray absorptiometry at baseline and follow-up.Lean mass and fat mass were positively associated with BMD of the spine, hip, and the total body at both baseline and follow-up. The association between fat mass and BMD at the spine at baseline (P = 0.210 and at the spine (P = 0.116 and hip (P = 0.073 in the second year was not statistically significant when height was adjusted. Six dietary patterns were identified but only cereal grains-fruits pattern (P = 0.001 in the spine, P = 0.037 in hip and milk-root vegetables pattern (P = 0.010 in hip were associated with BMD of the spine and hip. The linear mixed model of follow-up data showed that lean mass, years since menopause, and age of menophania were the significant determinants of BMD of all sites. Moreover, lean mass was the best determinant of BMD (VIP = 1.936.Lean mass, years since menopause, age of menophania and dietary patterns are the important determinants of BMD of the spine, hip, and the total body. Lean mass is the best determinant of BMD.

    Body weight and body mass index (BMI) are considered potentially modifiable determinants of bone mass. Therefore, the aim of this study was to explore the association between body weight and body mass index (BMI) with total hip and lumbar spine bone mineral density (BMD). This cross-sectional study included a population of 100 women and 32 men from Kosovo into three BMI groups. All the study subjects underwent dual-energy X-ray absorptiometry (DXA) measurements. Total hip BMD levels of obese menopausal and premenopausal women and men were significantly higher compared to overweight or normal weight subjects, while lumbar spine BMD levels of only menopausal women and men were higher among obese subjects. Age-adjusted linear regression analysis showed that BMI is a significant independent associate of lumbar spine and total hip BMD in menopausal women and men. Despite positive association between BMI and lumbar spine and total hip BMD in menopausal women, presence of more obese and osteoporotic subjects among menopausal women represent a population at risk for fractures because of poor balance and frequent falls; therefore, both obesity and osteoporosis prevention efforts should begin early on in life.

  15. The nature of Λ and the mass of the graviton: A critical view

    International Nuclear Information System (INIS)

    Gazeau, J.P.; Novello, M.

    2006-10-01

    The existence of a non-zero cosmological constant Λ gives rise to controversial interpretations. Is Λ a universal constant fixing the geometry of an empty universe, as fundamental as the Planck constant or the speed of light in the vacuum? Its natural place is then on the left-hand side of the Einstein equation. Is it instead something emerging from a perturbative calculus performed on the metric g μν solution of the Einstein equation and to which it might be given a material status of (dark or bright) 'energy'? It should then be part of the content of the right-hand side of the Einstein equations. The purpose of this paper is not to elucidate the fundamental nature of Λ, but instead we aim to present and discuss some of the arguments in favor of both interpretations of the cosmological constant. We will analyse the question of a Λ-dependent graviton mass, more precisely the possibility that between the Compton wavelength of the graviton and the cosmological constant there is the relation l g Λ 1/ 2 ≅ 1. Since a physical quantity like mass originates in a Minkowski conservation law, we proceed to a group theoretical interpretation of this relation in terms of the two possible Λ-deformations of the Poincare group, namely the de Sitter and anti de Sitter groups. We use a very suitable formula, the so-called Garidi mass, and the typically dS/AdS dimensionless parameter ℎH/mc 2 in order to make clear the asymptotic relations between Minkowski masses m and their possible dS/AdS counterparts. We conclude that if the fundamental of the geometry of space-time is Minkowskian, then the square of the mass of the graviton is proportional to Λ; otherwise, if the fundamental state is deSitter/AdS, then the graviton is massless in the deSitterian sense.

    In this study, we evaluated associations of experiences with mass media imported from Western nations such as the United States versus mass media from China and other Asian countries with eating and body image disturbances of young Chinese women. Participating women (N=456) completed self-report measures of disordered eating, specific sources of appearance dissatisfaction (fatness, facial features, stature), and Western versus Chinese/Asian mass media influences. The sample was significantly more likely to report perceived pressure from, comparisons with, and preferences for physical appearance depictions in Chinese/Asian mass media than Western media. Chinese/Asian media influences also combined for more unique variance in prediction models for all disturbances except stature concerns. While experiences with Western media were related to disturbances as well, the overall impact of Chinese/Asian media influences was more prominent. Copyright © 2016 Elsevier Ltd.

    The balance between osteoclast and osteoblast activity is central for maintaining the integrity of bone homeostasis. Here we show that mice lacking dendritic cell specific transmembrane protein (DC-STAMP), an essential molecule for osteoclast cell-cell fusion, exhibited impaired bone resorption and upregulation of bone formation by osteoblasts, which do not express DC-STAMP, which led to increased bone mass. On the contrary, DC-STAMP over-expressing transgenic (DC-STAMP-Tg) mice under the control of an actin promoter showed significantly accelerated cell-cell fusion of osteoclasts and bone resorption, with decreased osteoblastic activity and bone mass. Bone resorption and formation are known to be regulated in a coupled manner, whereas DC-STAMP regulates bone homeostasis in an un-coupled manner. Thus our results indicate that inhibition of a single molecule provides both decreased osteoclast activity and increased bone formation by osteoblasts, thereby increasing bone mass in an un-coupled and a tissue specific manner.

  18. The critical role of culture and environment as determinants of women's participation in computer science

    Science.gov (United States)

    Frieze, Carol

    This thesis proposes the need for, and illustrates, a new approach to how we think about, and act on, issues relating to women's participation, or lack of participation, in computer science (CS). This approach is based on a cultural perspective arguing that many of the reasons for women entering---or not entering---CS programs have little to do with gender and a lot to do with environment and culture. Evidence for this approach comes primarily from a qualitative, research study, which shows the effects of changes in the micro-culture on CS undergraduates at Carnegie Mellon, and from studies of other cultural contexts that illustrate a "Women-CS fit". We also discuss the interventions that have been crucial to the evolution of this specific micro-culture. Our argument goes against the grain of many gender and CS studies which conclude that the reasons for women's low participation in CS are based in gender --and particularly in gender differences in how men and women relate to the field. Such studies tend to focus on gender differences and recommend accommodating (what are perceived to be) women's different ways of relating to CS. This is often interpreted as contextualizing the curriculum to make it "female-friendly". The CS curriculum at Carnegie Mellon was not contextualized to be "female-friendly". Nevertheless, over the past few years, the school has attracted and graduated well above the US national average for women in undergraduate CS programs. We argue that this is due in large part to changes in the culture and environment of the department. As the environment has shifted from an unbalanced to a more balanced environment (balanced in terms of gender, breadth of student personalities, and professional support for women) the way has been opened for a range of students, including a significant number of women, to participate, and be successful, in the CS major. Our research shows that as men and women inhabit, and participate in, a more balanced environment

    The influence of giant dipole resonance (GDR) induced quadrupole moment on GDR width at low temperatures is investigated experimentally by measuring GDR width systematically in the unexplored temperature range T=0.8–1.5 MeV, for the first time, in A∼100 mass region. The measured GDR widths, using alpha induced fusion reaction, for {sup 97}Tc confirm that the GDR width remains constant at the ground state value up to a critical temperature and increases sharply thereafter with increase in T. The data have been compared with the adiabatic Thermal Shape Fluctuation Model (TSFM), phenomenological Critical Temperature Fluctuation Model (CTFM) and microscopic Phonon Damping Model (PDM). Interestingly, CTFM and PDM give similar results and agree with the data, whereas the TSFM differs significantly even after incorporating the shell effects.

    Based on analytic techniques that collapse data into a single average value, it has been reported that women lack category specificity and show genital sexual arousal to a large range of sexual stimuli including those that both match and do not match their self-reported sexual interests. These findings may be a methodological artifact of the way in which data are analyzed. This study examined whether using an analytic technique that models data over time would yield different results. Across two studies, heterosexual (N = 19) and lesbian (N = 14) women viewed erotic films featuring heterosexual, lesbian, and gay male couples, respectively, as their physiological sexual arousal was assessed with vaginal photoplethysmography. Data analysis with traditional methods comparing average genital arousal between films failed to detect specificity of genital arousal for either group. When data were analyzed with smoothing regression splines and a within-subjects approach, both heterosexual and lesbian women demonstrated different patterns of genital sexual arousal to the different types of erotic films, suggesting that sophisticated statistical techniques may be necessary to more fully understand women's genital sexual arousal response. Heterosexual women showed category-specific genital sexual arousal. Lesbian women showed higher arousal to the heterosexual film than the other films. However, within subjects, lesbian women showed significantly different arousal responses suggesting that lesbian women's genital arousal discriminates between different categories of stimuli at the individual level. Implications for the future use of vaginal photoplethysmography as a diagnostic tool of sexual preferences in clinical and forensic settings are discussed. © 2015 Society for Psychophysiological Research.

    This study examined the effectiveness of Kg-Free: an acceptance-, mindfulness- and compassion-based group intervention for women with overweight and obesity at post-treatment and 3-month follow-up and explored the psychological processes that underlie changes in quality of life, weight self-stigma, body mass index and emotional eating at post-treatment. Overall, 53 women completed Kg-Free. At post-treatment and 3-month follow-up, participants reported increased quality of life, mindfulness and self-compassion abilities and decreased weight self-stigma, emotional eating, shame, weight-related experiential avoidance, self-criticism and body mass index. Shame and self-criticism reductions were important mediators of changes in health-related outcomes, whereas weight-related experiential avoidance, mindfulness and self-compassion mediated changes in weight and eating-related outcomes.

    A recent result concerning the universality of the ratio of mass-gap amplitudes using the well known 1-D Heisenberg model which is the quantum version of the two-dimensional eight-vertex model is discussed. The believed extended scaling relation (x sub(p) = x sub(is an element of)/4) relating the polarization and energy anomalous dimensions is confirmed. The exponent, α, ν, γ sub(m) and γ sub(p) is also obtained by usual phenomenological renormalization group methods. (Author) [pt

    Full Text Available Background: The prevalence of obesity is increasing throughout the world. Obesity assessed by body mass index (BMI has shown to be associated with gestational complications while the relationship using waist circumference (WC is not clear yet. The present study was aimed to determine the relationship be-tween WC and adverse pregnancy complications.Methods: In this prospective cohort study, 1140 nulliparous pregnant women at 1st trimester of pregnancy referred to health care centers in Tabriz, Iran were enrolled in 2009-2010. Anthropometric indexes including (weight, height and WC were measured using standardized measures and methods. BMI was clas-sified into normal, overweight and obesity based on WHO classification. Ab-dominal obesity was defined as WC ≥ 88 cm. Pregnancy complication including gestational diabetes, hypertension and preeclamsia. Data were analyzed using SPSS, version 16.Results: Mean of BMI and WC were 24.32±4.08 kg/m2, 81.84±9.25cm at 1st trimester of pregnancy, respectively. Prevalence of overweight (BMI=25-29.9 kg/m2 and obesity (BMI>29.9 kg/m2 was 27.6%, 8.8%, respectively. Abdo-minal obesity based on WC was 34.8%. Significant correlations were found between BMI and WC (r=0.73, P =0.0001. Women with BMI>29.9 kg/m2 and WC>88 cm were more likely to suffer from gestational pregnancy and hyper-tension, as well as preeclampsia and preterm delivery.Conclusion: Early maternal WC similar to BMI is related with pregnancy complications.

    Full Text Available Bone marrow harbors a significant amount of body adipose tissue (BMAT. While BMAT might be a source of energy for bone modeling and remodeling, its increment can also represent impairment of osteoblast differentiation. The relationship between BMAT, bone mass and insulin sensitivity is only partially understood and seems to depend on the circumstances. The present study was designed to assess the association of BMAT with bone mineral density in the lumbar spine as well as with visceral adipose tissue, intrahepatic lipids, HOMA-IR, and serum levels of insulin and glucose. This cross-sectional clinical investigation included 31 non-diabetic women, but 11 had a pre-diabetes status. Dual X-ray energy absorptiometry was used to measure bone mineral density and magnetic resonance imaging was used to assess fat deposition in BMAT, visceral adipose tissue and liver. Our results suggest that in non-diabetic, there is an inverse relationship between bone mineral density in lumbar spine and BMAT and a trend persists after adjustment for weight, age, BMI and height. While there is a positive association between visceral adipose tissue and intrahepatic lipids with serum insulin levels, there is no association between BMAT and serum levels of insulin. Conversely, a positive relationship was observed between BMAT and serum glucose levels, whereas this association was not observed with other fat deposits. These relationships did not apply after adjustment for body weight, BMI, height and age. The present study shows that in a group of predominantly non-obese women the association between insulin resistance and BMAT is not an early event, as occurs with visceral adipose tissue and intrahepatic lipids. On the other hand, BMAT has a negative relationship with bone mineral density. Taken together, the results support the view that bone has a complex and non-linear relationship with energy metabolism.

    To evaluate the relevance of body mass index (BMI), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH ratio with clinical symptoms in polycystic ovary syndrome (PCOS) women. We reviewed the medical records of all women visited in the PCOS Clinic of Babol (Iran) from 2008 to 2012. A retrospective cross-sectional study was conducted on 175 PCOS women; aged 18-38 years diagnosed based on the Rotterdam criteria. Among the PCOs women, the prevalence of oligomenorrhea, acne, and hirsutism were found to be 92.0%, 31.4%, and 78.9%, respectively. Positive finding of polycystic ovaries was observed in 89.1% of PCOS women with by using sonography. A total of 69.2% overweight/obesity patients had polycystic ovary morphology on ultrasound image. Compared with non- overweight/obesity, the adjusted OR of PCOS women for sonographic view of polycystic ovaries was 4.33 (95% CI, 1.42-13.15, p=0.001), Nevertheless, the adjusted odds ratio (OR) showed no significant associations between LH, FSH, and LH/FSH ratio with clinical symptoms in these women. The findings of this study indicated that the overweight/obese women with PCOS are at an increased risk for sonographic view of polycystic ovaries. Therefore, it is suggested that successful weight loss is the most effective method of restoring ovulation, menstruation that should be used as major advice in obese PCOS patients.

    Fragment-based screening presents a promising alternative to high-throughput screening and has gained great attention in recent years. So far, only a few studies have discussed mass spectrometry as a screening technology for fragments. Herein, we report the application of native electrospray ionization mass spectrometry (MS) for screening defined sets of fragments against four different target proteins. Fragments were selected from a primary screening conducted with a thermal shift assay (TSA) and represented different binding categories. Our data indicated that, beside specific complex formation, many fragments show extensive multiple binding and also charge-state shifts. Both of these factors complicate automated data analysis and decrease the attractiveness of native MS as a primary screening tool for fragments. A comparison of the hits identified by native MS and TSA showed good agreement for two of the proteins. Furthermore, we discuss general challenges, including the determination of an optimal fragment concentration and the question of how to rank fragment hits according to their affinity. In conclusion, we consider native MS to be a highly valuable tool for the validation and deeper investigation of promising fragment hits rather than a method for primary screening. © 2017 Wiley-VCH Verlag GmbH & Co.

    Isotope ratio mass spectrometry (IRMS) has been used in numerous fields of forensic science in a source inference perspective. This review compiles the studies published on the application of isotope ratio mass spectrometry (IRMS) to the traditional fields of forensic science so far. It completes the review of Benson et al. [1] and synthesises the extent of knowledge already gathered in the following fields: illicit drugs, flammable liquids, human provenancing, microtraces, explosives and other specific materials (packaging tapes, safety matches, plastics, etc.). For each field, a discussion assesses the state of science and highlights the relevance of the information in a forensic context. Through the different discussions which mark out the review, the potential and limitations of IRMS, as well as the needs and challenges of future studies are emphasized. The paper elicits the various dimensions of the source which can be obtained from the isotope information and demonstrates the transversal nature of IRMS as a tool for source inference.

    This report is a preliminary document presenting an overview of the Critical Heat Flux (CHF) phenomenon, the High Pressure Critical Heat Flux facility (HPCHF), preliminary CHF data acquired, and the future direction of the research. The HPCHF facility has been designed and built to study CHF at high pressure and low mass flux ranges in a rod bundle prototypical of conceptual Small Modular Reactor (SMR) designs. The rod bundle is comprised of four electrically heated rods in a 2x2 square rod bundle with a prototypic chopped-cosine axial power profile and equipped with thermocouples at various axial and circumferential positions embedded in each rod for CHF detection. Experimental test parameters for CHF detection range from pressures of ~80 – 160 bar, mass fluxes of ~400 – 1500 kg/m2s, and inlet water subcooling from ~30 – 70°C. The preliminary data base established will be further extended in the future along with comparisons to existing CHF correlations, models, etc. whose application ranges may be applicable to the conditions of SMRs.

    Full Text Available The demand for lengthening the life cycle of the residential estate, engendered with the economical and housing crisis since the last few years, brings out, in the course of time, the need for conservation and improvement works of the property house performances, through the direct involvement of the users. The possibility of reducing maintenance and adjustment costs may develop into a project resource, consistent to the participation and cooperation principles, identifying social housing interventions. With this aim, the BETHA group of the d’Annunzio University is investigating the potentiality of technological transfer of the ‘mass customization’ process from the industrial products field to the social housing segment, by detecting issues, strategies and opportunities.

    2014-04-01

    The purpose of this study was to explore the perspectives of women diagnosed with co-occurring disorders on the treatments provided by a state psychiatric hospital so that appropriate recommendations for changes in treatment may be made. Critical ethnography was used and the data was viewed through the lens of intersectionality from the black feminist perspective. Seven women hospitalized in one psychiatric hospital in the Mid-Atlantic region participated in the study. Data was collected via semistructured interviews, Consumer Perceptions of Care survey, researcher's observations, and archival data. Three major findings emerged: (1) Dialectical Behavioral Therapy (DBT) was identified as a beneficial treatment, (2) a lack of trust in the system and people in the system, and (3) housing or homelessness was perceived as a barrier. Based on the results of this study, it is recommended clinicians, administrators, and policy makers listen closely to individuals receiving treatment to make decisions regarding treatment accordingly.

    We evaluated the hypothesis that greater lean mass promotes better overnight hydration, improved postural blood pressure and greater strength. Thirty women, aged 71 ± 0.9 years (mean ± SE), completed one measurement in a euhydrated state and another the following morning after an overnight fast. Measurements included hydration, lean mass, orthostatic blood pressure and strength. Participants were grouped by fat-free mass index (FFMI), with cut-points defined as low (blood pressure. On day 1, women with low FFMI experienced significant postural systolic blood pressure changes from sitting to standing (-11.3 ± 4.0 mmHg, p postural blood pressure and loss of strength that increases the risk for early morning falls.

    Transmission of obesity across generations is of concern. Offspring of obese women have short- and long-term increased morbidities. A high intake of carbohydrate during pregnancy combined with impaired glucose tolerance is postulated to result in high birth weight, which is linked to subsequent metabolic disease. The objective was to examine the association between carbohydrate intake in obese pregnant women and their offspring's body composition. Secondary analyses were performed in an observational setting of 222 pregnant women with a pregestational BMI (in kg/m(2)) ≥30 participating in a randomized controlled trial. Diet was assessed at gestational weeks 11-14 and 36-37 by using a semiquantitative food-frequency questionnaire. Body composition in the offspring was assessed at birth by dual-energy X-ray absorptiometry. Relative fat mass (%) was the primary outcome. Absolute measures (total fat, abdominal fat, and lean body mass) were secondary outcomes. Mean ± SD weight and absolute and relative fat mass in the offspring at birth were 3769 ± 542 g, 436 ± 214 g, and 11% ± 4%, respectively. Maternal intake of digestible carbohydrates was associated with the offspring's relative fat mass in late (P-trend = 0.006) but not early (P-trend = 0.15) pregnancy. A comparison of mothers in the highest (median: 238 g/d) compared with the lowest (median: 188 g/d) quartile of digestible carbohydrate intake showed a mean adjusted higher value in the offspring's relative fat mass of 2.1% (95% CI: 0.6%, 3.7%), which corresponded in absolute terms to a 103-g (95% CI: 27, 179-g) higher fat mass. Abdominal fat mass was also higher. In a strata of women with well-controlled glucose (2-h glucose values ≤6.6 mmol/L), no association between carbohydrate intake and offspring fat mass was observed, but the associations became significant and increased in strength with higher intolerance (strata with 2-h glucose values between 6.7-7.7 and ≥7.8 mmol/L). In obese women, even those

    Delayed access to antenatal care in high income countries is associated with poor maternal, fetal and neonatal outcomes. The aim was to synthesise the diverse body of evidence around women's views of early antenatal care and barriers to attendance in such countries. Critical Interpretive Synthesis integrates the process of systematic review with the qualitative methods of meta-ethnography and grounded theory, with a focus on theory generation to inform policy, practice and future research. Database searches were conducted, supplemented with reference and citation tracking and website searching between February 2014 and April 2016. Qualitative data analysis methods were used to extract and summarise the key themes from each study. A taxonomy of constructs was created, with the synthesis developed to thread these together. Fifty-four papers were synthesised, including qualitative, quantitative, mixed method and systematic review, published between 1987 and 2016. Seventeen constructs around the core concept of 'acceptance of personal and public pregnancies' were produced. Acceptance of the 'personal' pregnancy considers the contribution of mindset in the recognition and acceptance of pregnancy, influenced by knowledge of pregnancy symptoms, pregnancy planning and desire. Acceptance of the 'public' pregnancy considers women's assessment of the social consequences of pregnancy, and the relevance and priority of antenatal care. Critical Interpretive Synthesis offers a systematic yet creative approach to the synthesis of diverse evidence. The findings offer new perspectives on women's perceptions of early pregnancy and attendance for care, which may be used to facilitate timely antenatal provision for all pregnant women.

    2017-05-01

    As women's health has received significant political and media attention recently, I proposed an expanded structural theory of women's communication about health. Women's health communication and critical race and systemic racism research framed this study. I interviewed 15 communicators and community health workers from grass-roots organizations focused on women's health to learn of their challenges of communicating with women from communities experiencing health disparities. Findings suggest that communicators face difficulties in developing meaningful messaging for publics because of disjunctures between medical and community frames, issues in searching for health among women's many priorities, Whiteness discourses imposed on publics' experiences, and practices of correcting for power differentials. A structural theory of women's health communication, then, consists of tenets around geographic, research/funding, academic/industry, and social hierarchies. Six frames suggesting racial biases about women and health disparities are also defined. This study also includes practical solutions in education, publishing, and policy change for addressing structural challenges.

    The objective of this analysis was to assess risk factors for self-reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty-four percent of the participants reported OA. Older age (odds ratio (OR)(70-79 vs 50-59)=2.69, 95% confidence interval (CI)=2.60-2.78) and higher body mass index (BMI) (OR(BMI>or=40.0 vs or=30.0) was 57.9% in African Americans, 51.0% in American Indians, 41.9% in Hispanic whites, and 32.9% in non-Hispanic whites. The prevalence of other major OA risk factors was higher in African-American, American-Indian, and Hispanic white women than in non-Hispanic white women. Non-Hispanic white women who were in the extreme obese category (BMI>or=40.0 kg/m(2)) had a 2.80 times (95% CI=2.63, 2.99) greater odds of self-reported OA. The odds were even higher in American-Indian (OR=4.22, 95% CI=1.82, 9.77) and African-American (OR=3.31, 95% CI=2.79, 3.91) women, indicating a significant interactive effect of BMI and ethnicity on odds of OA. In conclusion, OA is a highly prevalent condition in postmenopausal women, and there are differential effects according to ethnicity.

  4. Association between body composition and body mass index in young Japanese women.

    The National Nutrition Survey of Japan indicated a trend toward a decreasing body mass index (BMI; kg/m2) among young Japanese women. Current studies suggest that not-high BMI often does not correlate with not-high body fat percentage. Recently, the classification of BMI in adult Asians was proposed by the International Obesity Task Force. The addition of an "at risk of overweight" category, BMI as 23.0-24.9, was intended to prevent chronic diseases. We investigated the association between body fat percentage (BF%) and BMI to evaluate the screening performance of BMI focused on individual preventive medicine. The subjects consisted of 605 female college students. The subjects' ages (y), heights (cm), body weights (kg), BMIs, and BF percents with underwater weighing expressed as the means +/- SD were 19.6 +/- 0.5, 158.7 +/- 5.6, 53.8 +/- 7.2, 21.3 +/- 2.4, and 24.9 +/- 4.9, respectively. We defined high BF% as +/- 85th percentile of BF% (29.8%). High-BF% individuals are often not classified into BMI > or = 23.0 because their BMI readings are very broad (18.4-31.7). In comparison to the screening performances (specificity and sensitivity), BMI > or = 23.0 (85.3% and 52.1%, respectively), rather than BMI > or = 25.0 (96.7% and 29.8%, respectively), is recommended for the mass evaluation of fatness. For this reason, the BMI "at risk of overweight" category is characterized as the threshold of increasing the appearance ratio of high-BF% individuals. In conclusion, the BMI > or = 25.0 kg/m2 category is determined as high BF%, regardless of body composition measurement for mass evaluation as a result of quite high specificity. Even so, body composition measurement is necessitated by the individual evaluation of fatness focused on preventive medicine because BMI performed a poor representation of body composition, especially BMI < 25.0 kg/m2 individuals.

    Lean body mass (LBM), quantified using computed tomography (CT), is a significant predictor of clinical outcomes in the critically ill. While CT analysis is precise and accurate in measuring body composition, it may not be practical or readily accessible to all patients in the intensive care unit (ICU). Here, we assessed the agreement between LBM measured by CT and four previously developed equations that predict LBM using variables (i.e. age, sex, weight, height) commonly recorded in the ICU. LBM was calculated in 327 critically ill adults using CT scans, taken at ICU admission, and 4 predictive equations (E1-4) that were derived from non-critically adults since there are no ICU-specific equations. Agreement was assessed using paired t-tests, Pearson's correlation coefficients and Bland-Altman plots. Median LBM calculated by CT was 45 kg (IQR 37-53 kg) and was significantly different (p LBM (error ranged from 7.5 to 9.9 kg), compared with LBM calculated by CT, suggesting insufficient agreement. Our data indicates a large bias is present between the calculation of LBM by CT imaging and the predictive equations that have been compared here. This underscores the need for future research toward the development of ICU-specific equations that reliably estimate LBM in a practical and cost-effective manner.

    Full Text Available This viewpoint aims to analyse the Criminal Law Amendment Act 2013 from a legal perspective. In doing so, it discusses the statutory safeguards of rights to a dignified life of a woman by analysing the various existing laws, which have been significantly amended to build the Criminal Act, 2013. These laws are: Indian Penal Code (IPC 1860; Indian Evidence Act 1872, Code of Criminal Procedure as amended in 1973, Immoral Trafficking Prevention Act 1956, Information Technology Act 2000, The Juvenile Justice (Care and Protection of Children Act 2000, The Protection of Women from Domestic Violence Act 2005, The Protection of Children from Sexual Offences Act, 2012, The Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal Act 2013. In the conclusion, I urge that although efficient laws are in operation in India towards protecting the right to live with dignity of women, however, incidents of violence against women are on the rise. Hence, a concerted effort in bringing appropriate attitudinal change is the task ahead for all Indians.

    Loss of both muscle and bone mass results in fragility fractures with increased risk of disability, poor quality of life, and death. Our aim was to assess the association between low appendicular lean mass (aLM) defined according to different criteria and low bone mineral density (BMD) in hip-fracture women. Six hundred fifty-three women admitted to our rehabilitation hospital underwent dual energy X-ray absorptiometry 19.1 ± 4.1 (mean ± SD) days after hip-fracture occurrence. Low aLM was identified according to either Baumgartner's definition (aLM/height 2 less than two standard deviations below the mean of the young reference group) or FNIH criteria: aLM definition, the association between low aLM/height 2 and low BMD was significant: χ 2 (1, n = 653) = 8.52 (p = 0.004), but it was erased by adjustments for age and fat mass. Using the FNIH definition the association between low aLM and low BMD was significant: χ 2 (1, n = 653) = 42.5 (p definition based on aLM/BMI ratio the association between low aLM/BMI ratio and low BMD was nonsignificant: χ 2 (1, n = 653) = 0.003 (p = 0.957). The association between low aLM and low BMD in women with hip fracture dramatically depends on the adopted definition of low aLM. FNIH threshold for aLM (<15.02 kg) emerges as a useful tool to capture women with damage of the muscle-bone unit.

    Evidence regarding endothelial function in both obese and nonobese women with PCOS is contradictory. It is unknown whether obese women with PCOS carry an increased risk related to body mass index (BMI). To identify endothelial function and investigate its relationship to body mass index and insulin resistance in young women with PCOS. Twenty-two obese women with PCOS (BMI 35.2 ± 3.2) as well as fourteen lean women (BMI 22.8 ± 2.1)with PCOS were included in the study. Fasting serum insulin, blood glucose were estimated and HOMA and Quicki index were calculated. All patients were subjected to ultrasound recording of brachial artery diameter at rest and after reactive hyperemia (FMD) for assessment of endothelial function. Ten age matched healthy females with normal BMI were chosen as a control group. There were higher basal insulin levels with lower Quicki index and higher HOMA index in women with PCOS than normal group, but the differences were significant only between obese PCOS subgroup and control. On the other hand, FMD was significantly and equally decreased in both groups of women with PCOS, compared with control subjects (3.7 ± 3.2% in the nonobese subgroup and 3.5 ± 2.8% in the obese one vs. 10.6 ± 4.1% in control subjects, P, 0.001). FMD was not correlated with BMI nor insulin resistance indices. Endothelial dysfunction is already present in young women with PCOS. In this patient group, it cannot be attributed to insulin resistance or obesity. © 2010 Asian Oceanian Association for the Study of Obesity . Published by Elsevier Ltd. All rights reserved.

    Carpathian Euroregion gathers the population of 5 countries, including Poland, Slovakia, Hungary and Romania- the European Union members, as well as Ukraine. Young women are statistically less involved in high-intensity physical activity than young men. The objective of this work was to assess the relation between physical activity of young women aged 18-21 years old and BMI and conditioning factors. The study was conducted between 2010 and 2011 among 2339 women. The Minnesota Leisure Time Physical Activity Questionnarie (MLTPAQ) was applied. It results from the study that 74,2% of young women is considered to have the proper BMI rate (18,5-24,9). As many as 16,2% is considered underweight and almost 10% have higher BMI rate and are overweight. More than one third of respondents did not gain the level of physical activity of 1000 kcal/week, and that is the minimum recommended amount of leisure physical activity time per week. In case of women with low level of physical activity (activity considered low-intensity activity EEPAlight. The character of changes of the BMI index with reference to the level of physical activity is very similar in the women from towns/cities and the women from villages. An increase of BMI along with the total physical activity was related among all to the increase of free fat mass FFM despite of the level of physical.

    Women with polycystic ovary syndrome (PCOS) are insulin-resistant and have increased risk for type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). But it is controversial whether the increased risk of CHD and T2DM is associated with endocrine abnormalities occurring as a consequence of PCOS or whether it is related to obesity or metabolic changes frequently seen in women with PCOS. Since both homocysteine (Hcy) and C-reactive protein (CRP) are supposed to predict T2DM and CHD, we investigated their possible relationship with insulin resistance, obesity, hyperandrogenemia and metabolic alterations in 44 PCOS women and 26 healthy controls matched by age and body mass index (BMI). Hcy and CRP levels were significantly elevated in PCOS women compared with controls (13.30 +/- 4.81 vs. 9.02 +/- 3.36 micromol/l, p PCOS such as testosterone and LH/FSH ratio (p > 0.05). Multiple regression analysis revealed BMI as the major factor examined that influenced both Hcy and CRP levels. In PCOS women, plasma levels of Hcy and CRP were significantly elevated compared with age- and BMI-matched controls. Although most of the PCOS-related endocrine and metabolic changes are related to elevated plasma Hcy and CRP levels in PCOS women, BMI seems to be the major factor determining CHD and T2DM in women with PCOS.

    Pre-pregnancy weight and gestational weight gain (GWG) are important factors in both maternal and infant outcomes. Little information is available in relation to different levels of pre-pregnancy body mass index (BMI) and body weight gain on obstetric outcomes in Taiwan. This study investigated the associations between pregnancy complications with pre-pregnant BMI and GWG, in Taiwanese women. Data were extracted from a delivery room information bank on all women delivering singleton babies in a medical center. Eight hundred and sixty pregnant women were included. The collected variables included basic information, GWG, and pregnancy and neonatal outcomes. Pregnant women were categorized according to their pre-pregnant BMI and GWG to evaluate the impacts of pre-pregnant BMI and maternal weight gain on the risk of pregnancy complications. Univariate and multivariable logistic regression analyses were performed, and odds ratios were calculated. Pre-pregnancy BMI>=24 kg/m2 increased the risks of gestational diabetes mellitus, preeclampsia, and preterm labor. Preeclampsia and Cesarean delivery were positively associated with high weight gains (>18 kg), whereas a low birth weight and preterm labor were strongly associated with low weight gains (14 kg in women who were underweight and normal weight before pregnancy. An appropriate maternal BMI (18.5-24 kg/m2) at conception followed by a suitable gestational weight gain (10-14 kg) has substantial impact on the overall health of pregnant women and would lead to better obstetric management for Taiwanese women.

Special effort has been made to reduce the experimental uncertainty of the B(E2, 2{sub 1}{sup +} {yields} 0{sub 1}{sup +}) value in {sup 178}Os, used for transition strength normalizations in {sup 178}Os necessary for the comparison with theoretical models. A second experiment was performed to measure the lifetime of the first excited 2{sup +} state in {sup 178}Os with the Koeln coincidence plunger device at the FN Tandem accelerator of the University of Cologne using THE {sup 166}Er({sup 16}O,4n){sup 178}Os reaction at E({sup 16}O) = 80 MeV. The resulting lifetime has been compared to the value obtained using the delayed coincidence method. (orig.)

    We set up a mechanistic agent-based model of a rapid mass transit system. Using empirical data from Singapore's unidentifiable smart fare card, we validate our model by reconstructing actual travel demand and duration of travel statistics. We subsequently use this model to investigate two phenomena that are known to significantly affect the dynamics within the RTS: (1) overloading in trains and (2) overcrowding in the RTS platform. We demonstrate that by varying the loading capacity of trains, a tipping point emerges at which an exponential increase in the duration of travel time delays is observed. We also probe the impact on the rail system dynamics of three types of passenger growth distribution across stations: (i) Dirac delta, (ii) uniform and (iii) geometric, which is reminiscent of the effect of land use on transport. Under the assumption of a fixed loading capacity, we demonstrate the dependence of a given origin-destination (OD) pair on the flow volume of commuters in station platforms.

    Pregnancy is accompanied by fat gain and insulin resistance. Changes in adipose tissue morphology and function during pregnancy and factors contributing to gestational insulin resistance are incompletely known. We sought to characterize adipose tissue in trimesters 1 and 3 (T1/T3) in normal weight (NW) and obese pregnant women, and identify adipose tissue-related factors associated with gestational insulin resistance. Twenty-two NW and 11 obese women were recruited early in pregnancy for the Pregnancy Obesity Nutrition and Child Health study. Examinations and sampling of blood and abdominal adipose tissue were performed longitudinally in T1/T3 to determine fat mass (air-displacement plethysmography); insulin resistance (homeostasis model assessment of insulin resistance, HOMA-IR); size, number and lipolytic activity of adipocytes; and adipokine release and density of immune cells and blood vessels in adipose tissue. Fat mass and HOMA-IR increased similarly between T1 and T3 in the groups; all remained normoglycemic. Adipocyte size increased in NW women. Adipocyte number was not influenced, but proportions of small and large adipocytes changed oppositely in the groups. Lipolytic activity and circulating adipocyte fatty acid-binding protein increased in both groups. Adiponectin release was reduced in NW women. Fat mass and the proportion of very large adipocytes were most strongly associated with T3 HOMA-IR by multivariable linear regression (R(2)=0.751, Pinsulin resistance.

    Full Text Available Abstract Background Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. Methods All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. Results In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004. Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR = 3.21, 95% confidence interval (CI: 1.15–8.47]. Conclusion The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

    Study objective: Older women with high bone mineral density (BMD) have an increased risk of breast cancer but it is not well known whether this association is associated with the stage of the tumor. The objective of the study is to determine if older women with high BMD are likely to develop a more aggressive form of breast cancer, as defined by mortality. Patients: We prospectively studied 1504 women who were 75 years of age or older at the entry in the study (range, 75-90 years), between 1992 and 1994. BMD was measured by dual-photon X-ray absorptiometry at three skeletal sites (trochanter, Ward's triangle, femoral neck). The women were followed for a mean of 7 years for the occurrence of breast cancer. Cox proportional-hazards models were used to obtain estimates of the relative risk of breast cancer and relative risk of death according to the BMD. Main results: Forty-five incident breast cancer cases were identified. In multivariate analyses of the risk of breast cancer for women in the highest tertile of BMD was greater than for women in the lowest tertile. Indeed, the women with a trochanter BMD in the highest tertile were at 2.3-fold increased risk compared with women in the lowest tertile. The women with highest tertile BMD measured at the Ward's triangle and at the femoral neck were respectively at 2.2-and 3.3-fold increased risk compared with women at the lowest risk. The 7-year survival rates were markedly less favorable for women in the second and third tertile of the three skeletal sites compared with the lowest tertile. The risk of death was greater for women in the highest tertile of BMD than for women in the lowest tertile at every skeletal site. Conclusion: Elderly women with high BMD have an increased risk of breast cancer, especially advanced cancer, compared with women with low BMD

    Full Text Available Abstract Background It has been suggested that bone loss and cognitive decline are co-occurring conditions, possibly due to their relationship with estrogen. Cognitive decline has been associated with various nutritional deficiencies as well. The purpose of this study was to determine if cognitive function is related to bone mineral density of various skeletal sites as well as to various dietary components. Methods Cross-sectional study with 97 healthy, Caucasian, postmenopausal women (59.4–85.0 years enrolled in a larger longitudinal study, investigating the effects of sodium on bone mass. The subjects were divided into two groups based on cognition scores. Group 1 represented lower and Group 2 higher scores on cognitive function. Bone mineral density from the whole body, lumbar spine, femur and forearm were measured with the Lunar DPX-MD instrument. Anthropometry was measured by standard methods. Cognition was assessed using the Mini Mental State Examination. Cumulative (over 2 years dietary intake from 3-day records was analyzed by Food Processor® (ESHA Research, Salem, OR and cumulative physical activity was assessed using Allied Dunbar National Fitness Survey for older adults. Results Subjects' cognition scores ranged from 22–30 (normal, 27–30, indicating all subjects had either mild or no cognitive impairment. Multiple Analysis of Covariance adjusted for age, height, weight, physical activity, alcohol, calcium, sodium and energy intake, showed a statistically significant association between cognition and bone mineral density of all measurable sites (η2 = 0.21, P 2 = 0.07, P = 0.050. Group 2 did have a significantly higher potassium intake (P = 0.023. In multiple regression, saturated fat had a significant negative relationship with cognitive function. Conclusions It appears mild degree of cognitive impairment may be a marker for lower bone mineral density as well as for a diet lower in carbohydrate and potassium intake, and higher

    Inductively coupled plasma optical emission spectroscopy (ICP-OES) and mass spectrometry (ICP-MS) can be considered as the most important tools in inorganic analytical chemistry. Huge progress has been made since the first analytical applications of the ICP. More stable RF generators, improved spectrometers and detection systems were designed along with the achievements gained from advanced microelectronics, leading to overall greatly improved analytical performance of such instruments. In contrast, for the vast majority of cases liquid sample introduction is still based on the pneumatic principle as described in the late 19th century. High flow pneumatic nebulizers typically demand the use of spray chambers as “aerosol filters” in order to match the prerequisites of an ICP. By this, only a small fraction of the nebulized sample actually contributes to the measured signal. Hence, the development of micronebulizers was brought forward. Those systems produce fine aerosols at low sample uptake rates, but they are even more prone for blocking or clogging than conventional systems in the case of solutions containing a significant amount of total dissolved solids (TDS). Despite the high number of publications devoted to liquid sample introduction, it is still considered the Achilles' heel of atomic spectrometry and it is well accepted, that the technology used for liquid sample introduction is still far from ideal, even when applying state-of-the-art systems. Therefore, this review is devoted to offer an update on developments in the field liquid sample introduction that had been reported until the year 2013. The most recent and noteworthy contributions to this field are discussed, trends are highlighted and future directions are outlined. The first part of this review provides a brief overview on theoretical considerations regarding conventional pneumatic nebulization, the fundamentals on aerosol generation and discusses characteristics of aerosols ideally

    Sarcopenia is considered to be a risk factor for osteoporotic fracture, which is a major health problem in elderly women. In this study, we aimed to investigate the association of sarcopenia, with regard to muscle mass and function, with prevalent vertebral fracture in community-dwelling elderly women. We recruited 1281 women aged 64 to 87 years from the Korean Urban Rural Elderly cohort study. Muscle mass and function were measured using bioimpedance analysis and jumping mechanography. Skeletal muscle index (SMI) and jump power were used as an indicator of muscle mass and function, respectively. Among the participants, we observed 282 (18.9%) vertebral fractures and 564 (44.0%) osteoporosis. Although age, body mass index, and prevalence of osteoporosis increased as both SMI and jump power decreased, prevalence of vertebral fracture increased only when jump power decreased. In univariate analysis, compared with the highest quartile of jump power, the lowest quartile had a significant odds ratio of 2.80 (95% CI 1.79-4.36) for vertebral fracture. This association between jump power and vertebral fracture remained significant, with an odds ratio of 3.04 (95% CI 1.77-5.23), even after adjusting for other risk factors including age, bone mineral density, previous fracture, and cognitive function. In contrast, there was no association between SMI and vertebral fracture. Based on our results, low jump power, but not SMI, is associated with vertebral fracture in community-dwelling elderly Korean women. This finding suggests that jump power may have a more important role than muscle mass itself for osteoporotic fracture.

    OBJECTIVES To determine if body weight (BMI) is independently associated with cognitive function in postmenopausal women and the relationship between body fat distribution as estimated by waist-hip-ratio (WHR) and cognitive function. DESIGN Cross-sectional data analysis SETTING Baseline data from the Women's Health Initiative (WHI) hormone trials. PARTICIPANTS 8745 postmenopausal women aged 65–79 years, free of clinical evidence of dementia and completed baseline evaluation in the Women's Health Initiative (WHI) hormone trials. MEASUREMENTS Participants completed a Modified Mini-Mental State Examination (3MSE), health and lifestyle questionnaires, and standardized measurements of height, weight, body circumferences and blood pressure. Statistical analysis of associations between 3MSE scores, BMI and WHR after controlling for known confounders. RESULTS With the exception of smoking and exercise, vascular disease risk factors, including hypertension, waist measurement, heart disease and diabetes, were significantly associated with 3MSE score and were included as co-variables in subsequent analyses. BMI was inversely related to 3MSE scores, for every 1 unit increase in BMI, 3MSE decrease 0.988 (p=.0001) after adjusting for age, education and vascular disease risk factors. BMI had the most pronounced association with poorer cognitive functioning scores among women with smaller waist measurements. Among women with the highest WHR, cognitive scores increased with BMI. CONCLUSION Increasing BMI is associated with poorer cognitive function in women with smaller WHR. Higher WHR, estimating central fat mass, is associated with higher cognitive function in this cross-sectional study. Further research is needed to clarify the mechanism for this association.

    The twofold greater lifetime risk of fracturing a bone for white women compared with white men and black women has been attributed in part to differences in how the skeletal system accumulates bone mass during growth. On average, women build more slender long bones with less cortical area compared with men. Although slender bones are known to have a naturally lower cortical area compared with wider bones, it remains unclear whether the relatively lower cortical area of women is consistent with their increased slenderness or is reduced beyond that expected for the sex-specific differences in bone size and body size. Whether this sexual dimorphism is consistent with ethnic background and is recapitulated in the widely used mouse model also remains unclear. We asked (1) do black women build bones with reduced cortical area compared with black men; (2) do white women build bones with reduced cortical area compared with white men; and (3) do female mice build bones with reduced cortical area compared with male mice? Bone strength and cross-sectional morphology of adult human and mouse bone were calculated from quantitative CT images of the femoral midshaft. The data were tested for normality and regression analyses were used to test for differences in cortical area between men and women after adjusting for body size and bone size by general linear model (GLM). Linear regression analysis showed that the femurs of black women had 11% lower cortical area compared with those of black men after adjusting for body size and bone size (women: mean=357.7 mm2; 95% confidence interval [CI], 347.9-367.5 mm2; men: mean=400.1 mm2; 95% CI, 391.5-408.7 mm2; effect size=1.2; pbone size (women: mean=350.1 mm2; 95% CI, 340.4-359.8 mm2; men: mean=394.3 mm2; 95% CI, 386.5-402.1 mm2; effect size=1.3; pbone size (female: mean=0.73 mm2; 95% CI, 0.71-0.74 mm2; male: mean=0.70 mm2; 95% CI, 0.68-0.71 mm2; effect size=0.74; p=0.04, GLM). Female femurs are not simply a more slender version of male

    To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the polycystic ovary syndrome, another with the same age, educational status and presence or absence of sexual partners was sought without this diagnosis. In total, 166 patients agreed to participate, consisting of 95 diagnosed with polycystic ovary syndrome and 71 in the Control Group. The diagnosis of polycystic ovary syndrome was made by the presence of two from three criteria: oligomenorrhea or amenorrhea, clinical or biochemical hyperandrogenism and polycystic ovaries on transvaginal ultrasound, following exclusion of patients with Cushing's syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors. Weight and height were measured to calculate the body mass index. The Self-Reporting Questionnaire, which evaluated 20 items, was used as an indicator of common mental disorders. A χ² analysis stratified by the category of body mass index was used to compare the prevalence of common mental disorders, between the groups of women with and without the polycystic ovary syndrome. There were no significant differences in age, education, presence of sexual partners, ethnicity, socioeconomic status, use of psychiatric medication, and search for consultation in mental health between the studied groups. The prevalence of obese women with indications of common mental disorders was significantly higher in women with polycystic ovary syndrome than in the Control Group. In the group with healthy body mass index, the incidence of common mental disorders was statistically significant different between women with polycystic ovary syndrome and normal controls (p=0.008). Women with diagnosis of this

    Intergovernmental agencies have recognized that inconsistencies in the way that nation states regulate commerce in human kidneys lubricate transplant tourism, and have repeatedly exhorted recalcitrant governments of both organ-importing and organ-exporting nations to criminalize the exchange of cash for kidneys. Yet these same organizations have elected to remain silent on inconsistencies in the regulation of the trade in human eggs that lubricate fertility tourism. This article is a critical feminist analysis of this paradox. Sketches of the histories of regulation of the global markets in human kidneys and human eggs allow attribution of the different approaches to sales of kidneys and eggs to the triumph of neo-liberalism in the 1990s. Neo-liberalism supports the growth of the medical tourism industry and its niche market catering for infertility, and is responsible for exacerbating the relative disadvantage of poor and powerless women in destination countries, thereby creating the conditions for 'bioavailability', that is, the willingness to exchange body parts for cash. The paper identifies a disturbing correlation between deeply engrained conservative attitudes to women and a plentiful supply of eggs, and concludes by suggesting that what women need to lift themselves out of poverty and discrimination is secure and dignified work.

    E. coli is the most frequently used host for production of enzymes and other proteins by recombinant DNA technology. E. coli is preferable for its relative simplicity, inexpensive and fast high-density cultivation, well-known genetics, and large number of compatible molecular tools available. Despite all these advantages, expression and production of recombinant enzymes are not always successful and often result in insoluble and nonfunctional proteins. There are many factors that affect the success of cloning, expression, and mass production of enzymes by recombinant E. coli. In this paper, these critical factors and approaches to overcome these obstacles are summarized focusing controlled expression of target protein/enzyme in an unmodified form at industrial level.

    It is suggested a fast and accurate computation method for the prediction of mass flowrate in critical flows initially subcooled liquid from ''long'' discharge channels (high LID values). Starting from a previous very simple correlation proposed by the authors, further improvements in the model enable to widen the method reliability up to initial saturation conditions. A comparison of computed values with 145 experimental data regarding several investigations carried out at the Heat Transfer Laboratory (TERM/ISP, ENEA Casaccia) shows an excellent agreement. The computed data shifting from experimental ones is within ±10% for almost all data, with a slight increase towards low inlet subcoolings. The average error, for all the considered data, is 4,6%

    The effects of job strain and shift work on weight gain have not been studied jointly. Cross-sectional and longitudinal studies on shift work and weight gain have reported different results. This study examines potential effect modification by job strain on the link between shift work and weight gain, and concurrent and delayed effects of shift work on weight gain. Data came from 52 622 women who participated in the Nurses' Health Study II, a prospective cohort study. Using linear regression, we modelled change in body mass index (BMI) over 4 years as a function of change in job strain, cumulative exposure to rotating night shift previously and during the 4 years (ie, previous and concurrent exposures) and the interaction between job strain and concurrent shift work exposure. Age, race/ethnicity, pregnancy history, baseline BMI, job types and health behaviours at baseline were controlled for. Job strain and rotating shift work, concurrent and previous, all had independent associations with BMI change during the 4-year period. There was no evidence for effect modification by job strain. Concurrent and previous exposures to rotating night shift had different associations with BMI change: an inverted U-shape for concurrent exposure (ranging from 0.01 to 0.14 kg/m 2 increase), a dose-response for previous exposure (-0.02 to 0.09 kg/m 2 ). Job strain and rotating night shift work have independent contributions to weight gain. Reducing job strain and supporting night shift workers are both important intervention goals.

    Full Text Available The aims of the study were to establish the prevalence of high bone mass (HBM in a cohort of Spanish postmenopausal women (BARCOS and to assess the contribution of LRP5 and DKK1 mutations and of common bone mineral density (BMD variants to a HBM phenotype. Furthermore, we describe the expression of several osteoblast-specific and Wnt-pathway genes in primary osteoblasts from two HBM cases. A 0.6% of individuals (10/1600 displayed Z-scores in the HBM range (sum Z-score >4. While no mutation in the relevant exons of LRP5 was detected, a rare missense change in DKK1 was found (p.Y74F, which cosegregated with the phenotype in a small pedigree. Fifty-five BMD SNPs from Estrada et al. [NatGenet 44:491-501,2012] were genotyped in the HBM cases to obtain risk scores for each individual. In this small group of samples, Z-scores were found inversely related to risk scores, suggestive of a polygenic etiology. There was a single exception, which may be explained by a rare penetrant genetic variant, counterbalancing the additive effect of the risk alleles. The expression analysis in primary osteoblasts from two HBM cases and five controls suggested that IL6R, DLX3, TWIST1 and PPARG are negatively related to Z-score. One HBM case presented with high levels of RUNX2, while the other displayed very low SOX6. In conclusion, we provide evidence of lack of LRP5 mutations and of a putative HBM-causing mutation in DKK1. Additionally, we present SNP genotyping and expression results that suggest additive effects of several genes for HBM.

    Summary Body mass index (BMI) is now the most widely used measure of adiposity on a global scale. Nevertheless, intense discussion centers on the appropriateness of BMI as a phenotypic marker of adiposity across populations differing in race and ethnicity. BMI-adiposity relations appear to vary significantly across race/ethnic groups, but a collective critical analysis of these effects establishing their magnitude and underlying body shape/composition basis is lacking. Accordingly, we systematically review the magnitude of these race-ethnic differences across non-Hispanic (NH) white, NH black and Mexican American adults, their anatomic body composition basis and potential biologically linked mechanisms, using both earlier publications and new analyses from the US National Health and Nutrition Examination Survey. Our collective observations provide a new framework for critically evaluating the quantitative relations between BMI and adiposity across groups differing in race and ethnicity; reveal new insights into BMI as a measure of adiposity across the adult age-span; identify knowledge gaps that can form the basis of future research and create a quantitative foundation for developing BMI-related public health recommendations.

Nevertheless, intense discussion centers on the appropriateness of BMI as a phenotypic marker of adiposity across populations differing in race and ethnicity. BMI-adiposity relations appear to vary significantly across race/ethnic groups, but a collective critical analysis of these effects establishing their magnitude and underlying body shape/composition basis is lacking. Accordingly, we systematically review the magnitude of these race-ethnic differences across non-Hispanic (NH) white, NH black and Mexican American adults, their anatomic body composition basis and potential biologically linked mechanisms, using both earlier publications and new analyses from the US National Health and Nutrition Examination Survey. Our collective observations provide a new framework for critically evaluating the quantitative relations between BMI and adiposity across groups differing in race and ethnicity; reveal new insights into BMI as a measure of adiposity across the adult age-span; identify knowledge gaps that can form the basis of future research and create a quantitative foundation for developing BMI-related public health recommendations. © 2015 World Obesity.

    The floating catalyst chemical vapor deposition (FC-CVD) process permits macro-scale assembly of nanoscale materials, enabling continuous production of carbon nanotube (CNT) aerogels. Despite the intensive research in the field, fundamental uncertainties remain regarding how catalyst particle dynamics within the system influence the CNT aerogel formation, thus limiting effective scale-up. While aerogel formation in FC-CVD reactors requires a catalyst (typically iron, Fe) and a promotor (typically sulfur, S), their synergistic roles are not fully understood. This paper presents a paradigm shift in the understanding of the role of S in the process with new experimental studies identifying that S lowers the nucleation barrier of the catalyst nanoparticles. Furthermore, CNT aerogel formation requires a critical threshold of Fe x C y  > 160 mg/m 3 , but is surprisingly independent of the initial catalyst diameter or number concentration. The robustness of the critical catalyst mass concentration principle is proved further by producing CNTs using alternative catalyst systems; Fe nanoparticles from a plasma spark generator and cobaltocene and nickelocene precursors. This finding provides evidence that low-cost and high throughput CNT aerogel routes may be achieved by decoupled and enhanced catalyst production and control, opening up new possibilities for large-scale CNT synthesis.

    Domestic abuse represents a serious public health and human rights concern. Interventions to reduce the risk of abuse include staff training and standardized documentation improving detection and adherence to referral pathways. Interventional studies have been conducted in primary care, maternity and outpatient settings. Women disclosing abuse in emergency departments differ from women attending other healthcare settings, and it is unclear whether these interventions can be transferred to the emergency care setting. This review examines interventional studies to evaluate the effectiveness of emergency department-based interventions in reducing domestic abuse-related morbidity. Medline, EMBASE, CINAHL, PsycINFO and Cochrane Library were searched, according to prespecified selection criteria. Study quality was assessed using the Jadad scale. Of 273 search results, nine were eligible for review. Interventions involving staff training demonstrated benefits in subjective measures, such as staff knowledge regarding abuse, but no changes in clinical practice, based on detection and referral rates. When staff training was implemented in conjunction with supporting system changes - for example, standardized documentation for assessment and referral - clinically relevant improvements were noted. Interventions centred around staff training are insufficient to bring about improvements in the management and, thus, outcome of patients suffering abuse. Instead, system changes, such as standardized documentation and referral pathways, supported by training, may bring about beneficial changes. It remains uncertain whether surrogate outcomes employed by most studies translate to changes in abuse-related morbidity: the ultimate goal.

    Given the absence of effective population-based screening tests for ovarian, uterine, vaginal, and vulvar cancers, early detection can depend on women and health care providers recognizing the potential significance of symptoms. In 2008, the Centers for Disease Control and Prevention’s (CDC) Inside Knowledge campaign began distributing consumer education materials promoting awareness of gynecologic cancer symptoms. We investigated providers’ in-office use of CDC gynecologic cancer materials and their recognition of the symptoms highlighted in the materials. We analyzed data from a national 2012 survey of US primary care physicians, nurse practitioners, and gynecologists (N = 1,380). Less than a quarter of providers (19.4 %) reported using CDC gynecologic cancer education materials in their offices. The provider characteristics associated with the use of CDC materials were not consistent across specialties. However, recognition of symptoms associated with gynecologic cancers was consistently higher among providers who reported using CDC materials. The possibility that providers were educated about gynecologic cancer symptoms through the dissemination of materials intended for their patients is intriguing and warrants further investigation. Distributing consumer education materials in health care provider offices remains a priority for the Inside Knowledge campaign, as the setting where women and health care providers interact is one of the most crucial venues to promote awareness of gynecologic cancer symptoms.

    Full Text Available Abstract Background The diagnosis, treatment and prevention of osteoporosis is a national health emergency. Osteoporosis quietly progresses without symptoms until late stage complications occur. Older patients are more commonly at risk of fractures due to osteoporosis. The fracture risk increases when suppressive doses of levothyroxine are administered especially in postmenopausal women. The question is; "When should bone mass density be tested in postmenopausal women after the initiation of suppressive levothyroxine therapy?". Standard guidelines for the prevention of osteoporosis suggest that follow-up be done in 1 to 2 years. We were interested in predicting the level of bone mass density in postmenopausal women after the initiation of suppressive levothyroxine therapy with a novel approach. Methods The study used data from the literature on the influence of exogenous thyroid hormones on bone mass density. Four cubic polynomial equations were obtained by curve fitting for Ward's triangle, trochanter, spine and femoral neck. The behaviors of the models were investigated by statistical and mathematical analyses. Results There are four points of inflexion on the graphs of the first derivatives of the equations with respect to time at about 6, 5, 7 and 5 months. In other words, there is a maximum speed of bone loss around the 6th month after the start of suppressive L-thyroxine therapy in post-menopausal women. Conclusion It seems reasonable to check bone mass density at the 6th month of therapy. More research is needed to explain the cause and to confirm the clinical application of this phenomenon for osteoporosis, but such an approach can be used as a guide to future experimentation. The investigation of change over time may lead to more sophisticated decision making in a wide variety of clinical problems.

    This study examined the relationship between self-esteem, restrained eating, body image and body mass index during pregnancy. A total of 110 pregnant Israeli and UK women completed the Rosenberg Self-Esteem Questionnaire, the Dutch Eating Behaviour Questionnaire, scales to assess body image and demographics. Body mass index was calculated from antenatal records. Regression modelling determined the relationship between variables, countries and body mass index categories. High correlations were found between body image and body mass index with significantly higher body dissatisfaction for Israeli women. Self-esteem scores for pregnant women were similar to those reported for non-pregnant women. Poorer body image and higher prevalence of restrained eating were found in healthy weight Israeli women. © The Author(s) 2013.

    Numerous Web-based interventions have been implemented to promote health and health-related behaviors in persons with chronic conditions. Using randomized controlled trials to evaluate such interventions creates a range of challenges, which in turn can influence the study outcome. Applying a critical perspective when evaluating Web-based health interventions is important. The objective of this study was to critically analyze and discuss the challenges of conducting a Web-based health intervention as a randomized controlled trial. The MODIAB-Web study was critically examined using an exploratory case study methodology and the framework for analysis offered through the Persuasive Systems Design model. Focus was on technology, study design, and Web-based support usage, with special focus on the forum for peer support. Descriptive statistics and qualitative content analysis were used. The persuasive content and technological elements in the design of the randomized controlled trial included all four categories of the Persuasive Systems Design model, but not all design principles were implemented. The study duration was extended to a period of four and a half years. Of 81 active participants in the intervention group, a maximum of 36 women were simultaneously active. User adherence varied greatly with a median of 91 individual log-ins. The forum for peer support was used by 63 participants. Although only about one-third of the participants interacted in the forum, there was a fairly rich exchange of experiences and advice between them. Thus, adherence in terms of social interactions was negatively affected by limited active participation due to prolonged recruitment process and randomization effects. Lessons learned from this critical analysis are that technology and study design matter and might mutually influence each other. In Web-based interventions, the use of design theories enables utilization of the full potential of technology and promotes adherence. The

    Standardised pain assessment i.e. the McGill Pain Questionnaire provide an elicited pain language. Midwives observe spontaneous non-elicited pain language to guide their assessment of how a woman is coping with labour. This paper examined the labour pain experience using the questions: What type of pain language do women use? Do any of the words match the descriptors of standardised pain assessments? What type of information doverbal and non-verbal cues provide to the midwife? A literature search was conducted in 2013. Studies were included if they had pain as the primary outcome and examined non-elicited pain language from the maternal perspective. A total of 12 articles were included. The analysis revealed six categories in which labour pain can be viewed: 'positive', 'negative', 'physical', 'emotional', 'transcendent' and 'natural'. Women's language comprised i.e. prefixes and suffixes, which indicate the qualities of pain, and figurative language. Language indicated location of pain, gave insight into other life phenomena i.e. death, and shared similarities with standardised pain assessmentdescriptors. Labour cues were 'functional', 'dysfunctional,' or 'neutral' (part of the physiological childbirth process), and were verbal, non-verbal, emotional, psychological, physical behaviour or reactions, or tactile. Labour can bring about a spectrum of sensations and therefore emotions from happiness and pleasure to suffering and grief. Spontaneous pain language comprises verbal language and non-verbal behaviour. Narratives are an effective form of pain communication in that they provide details regarding the quality, nature and dimensions of pain, and details notcaptured in quantitative data.

    This study compares the pharmacokinetics (PK) of levonorgestrel (LNG) emergency contraceptive (EC) and ulipristal acetate (UPA)-EC between normal-body mass index (BMI) and obese-BMI women. This prospective, randomized crossover study evaluates the PK of women after single doses of LNG-EC (1.5mg) and UPA-EC (30mg). Study procedures took place during clinical research unit admissions, where participants received a standardized meal and each study drug, in random order, during two separate 24-h admissions. Study staff collected 14 blood specimens (0, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 10, 12, 16, 24 and 48h). We evaluated serum concentrations of LNG and UPA using liquid chromatography-tandem mass spectroscopy and estimated the PK parameters of both drugs using noncompartmental analysis. The main outcome of this study was a comparison of between-group differences in AUC 0-24 . Thirty-two women completed the study (16 in each group). Among normal-BMI and obese-BMI participants, the mean BMIs were 22.0 (range 18.8-24.6) and 34.3 (range 30.6-39.9), respectively. After LNG-EC, mean AUC 0-24 and maximum concentration (C max ) were 50% lower among obese-BMI women than among normal-BMI women (AUC 0-24 100.8 vs. 208.5ng*h/mL, IQR obese-BMI 35.8, IQR normal-BMI 74.2, p≤.01; C max 10.8 vs. 18.2ng/mL, p=.01). After UPA-EC, AUC 0-24 and C max were similar between obese-BMI and normal-BMI women (AUC 0-24 362.5 vs. 293.5ng*h/mL, IQR obese-BMI 263.2, IQR normal-BMI 112.5, p=.15; C max 95.6 vs. 89.3ng/mL, p=.70). After a single dose of EC, obese-BMI women are exposed to lower concentrations of LNG and similar concentrations of UPA, when compared to normal-BMI women. Differences in LNG-EC PK by BMI group may underlie and account for the lower LNG-EC efficacy reported among obese-BMI women, but modest differences in UPA-EC PK by BMI group provide less support for variable efficacy. A pharmacodynamic study may be able to clarify whether these PK differences account for observed differences

    To assess features and peculiarities of postmenopausal osteoporosis (OP) in women with normal body mass, overweight and obesity. Dual energy X-ray absorptiometry of the lumbal spine (Lunar DPX) and distal radius X-ray absorptiometry (DTX 200) were performed during cross-section study of 730 symptomatic postmenopausal women. OP was diagnosed in 253 (34.7%) women, 30.5% of them had normal body mass, 43.2% had overweight and 26.3% were obese. Among them 227 had atraumatic fractures at the age over 50 years. Obese OP patients had significantly higher frequency of arterial hypertension, chronic heart failure, osteoarthritis and glucose metabolism disorders than osteoporotic patients with normal body mass. Fracture frequency did not differ between groups with normal body mass, overweight and obesity. Excessive body mass did not decrease fracture risk in women with postmenopausal OP.

    Body mass index (BMI) is the most commonly used quantitative measure of adiposity. It is a kind of complex genetic diseases which are caused by multiple susceptibility genes. The first intron of fat mass and obesity-associated (FTO) has been widely discovered to be associated with BMI. Retinitis pigmentosa GTPase regulator-interacting protein-1 like (RPGRIP1L) is located in the upstream region of FTO and has been proved to be linked with obesity through functional tests. We carried out a genetic association analysis to figure out the role of the FTO gene and the RPGRIP1L gene in BMI. A quantitative traits study with 6,102 Chinese female samples, adjusted for age, was performed during our project. Among the twelve SNPs, rs1421085, rs1558902, rs17817449, rs8050136, rs9939609, rs7202296, rs56137030, rs9930506 and rs12149832 in the FTO gene were significantly associated with BMI after Bonferroni correction. Meanwhile, rs9934800 in the RPGRIP1L gene showed significance with BMI before Bonferroni correction, but this association was eliminated after Bonferroni correction. Our results suggested that genetic variants in the FTO gene were strongly associated with BMI in Chinese women, which may serve as targets of pharmaceutical research and development concerning BMI. Meanwhile, we didn't found the significant association between RPGRIP1L and BMI in Chinese women.

    Body mass index (BMI) may be an important factor affecting breast cancer outcome. Studies conducted mainly in Western countries have reported a relationship between higher BMI and a higher risk of all-cause death or breast cancer-specific death among women with breast cancer, but only a few studies have been reported in Japan so far. In the present prospective study, we investigated the associations between BMI and the risk of all-cause and breast cancer-specific death among breast cancer patients overall and by menopausal status and hormone receptor status. The study included 653 breast cancer patients admitted to a single hospital in Japan, between 1997 and 2005. BMI was assessed using a self-administered questionnaire. The patients were completely followed up until December, 2008. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated according to quartile points of BMI categories, respectively: <21.2, ≥21.2 to <23.3 (reference), ≥23.3 to <25.8 and ≥25.8 kg/m 2 . During the follow-up period, 136 all-cause and 108 breast cancer-specific deaths were observed. After adjustment for clinical and confounding factors, higher BMI was associated with an increased risk of all-cause death (HR = 2.61; 95% CI: 1.01–6.78 for BMI ≥25.8 vs. ≥21.2 to <23.3 kg/m 2 ) among premenopausal patients. According to hormonal receptor status, BMI ≥25.8 kg/m 2 was associated with breast cancer-specific death (HR = 4.95; 95% CI: 1.05–23.35) and BMI <21.2 kg/m 2 was associated with all-cause (HR = 2.91; 95% CI: 1.09–7.77) and breast cancer-specific death (HR = 7.23; 95% CI: 1.57–33.34) among patients with ER + or PgR + tumors. Analysis by hormonal receptor status also showed a positive association between BMI and mortality risk among patients with ER + or PgR + tumors and with BMI ≥21.2 kg/m 2 (p for trend: 0.020 and 0.031 for all-cause and breast cancer-specific death, respectively). Our results suggest that both higher BMI and lower BMI are associated

    Obesity and osteoporosis are two important public health problems that greatly impact mortality and morbidity. Several similarities between these complex diseases have been identified. The aim of this study was to analyze if different body mass indexes (BMIs) are associated with variations in bone mineral density (BMD) among postmenopausal Mexican-Mestizo women with normal weight, overweight, or different degrees of obesity. We studied 813 postmenopausal Mexican-Mestizo women. A structured questionnaire for risk factors was applied. Height and weight were used to calculate BMI, whereas BMD in the lumbar spine (LS) and total hip (TH) was measured by dual-energy x-ray absorptiometry. We used ANCOVA to examine the relationship between BMI and BMDs of the LS, TH, and femoral neck (FN), adjusting for confounding factors. Based on World Health Organization criteria, 15.13% of women had normal BMI, 39.11% were overweight, 25.96% had grade 1 obesity, 11.81% had grade 2 obesity, and 7.99% had grade 3 obesity. The higher the BMI, the higher was the BMD at the LS, TH, and FN. The greatest differences in size variations in BMD at these three sites were observed when comparing women with normal BMI versus women with grade 3 obesity. A higher BMI is associated significantly and positively with a higher BMD at the LS, TH, and FN.

    Full Text Available Background: Excess weight contributes to the development and progression of Type 2 diabetes mellitus (T2DM. Distorted body image amongst urban Black women and the perception that thinness is linked with HIV, may however be compounding the problem, particularly in areas with a high HIV burden. Objectives: This study aimed to compare the perception of body image in urban Black women with and without T2DM. Methods: A cross-sectional comparative study was conducted on 328 Black women systematically sampled into two groups (with and without T2DM. Body mass index (BMI (weight [kg]/height[m2] was determined and the adapted Stunkard Body Image Silhouettes for Black women was used to determine perceived body image (PBI. Results: Seventy-two per cent had T2DM and in this group 89% were obese, with a mean BMI of 39.5 kg/m2 (s.d. ± 8.5. In the non-diabetes group (NDG 44% were obese, with a mean BMIof 31.3 kg/m2 (s.d. ± 9.0 Black women underestimated their body image across all weight categories (p < 0.05. Both groups (99% of the study group also perceived thinness as being associated with HIV. Conclusions: This study identified an incongruence between PBI and actual BMI amongst urban Black women. This, combined with their belief that thinness is associated with HIV, places those with T2DM at risk of secondary complications arising from diabetes mellitus, and those without diabetes mellitus at a higher risk of developing T2DM. A discrepancy between PBI and BMI may therefore serve as a risk marker to alert clinicians to use a more ethno-cultural specific approach in engaging with urban Black women regarding weight loss strategies in the future.

    Hip fracture risk is known to increase with physical inactivity and decrease with obesity, but there is little information on their combined effects. We report on the separate and combined effects of body mass index (BMI) and physical activity on hospital admissions for hip fracture among postmenopausal women in a large prospective UK study. Baseline information on body size, physical activity, and other relevant factors was collected in 1996-2001, and participants were followed for incident hip fractures by record linkage to National Health Service (NHS) hospital admission data. Cox regression was used to calculate adjusted relative risks of hip fracture. Among 925,345 postmenopausal women followed for an average of 6.2 years, 2582 were admitted to hospital with an incident hip fracture. Hip fracture risk increased with decreasing BMI: Compared with obese women (BMI of 30+ kg/m(2) ), relative risks were 1.71 [95% confidence interval (CI) 1.47-1.97)] for BMI of 25.0 to 29.9 kg/m(2) and 2.55 (95% CI 2.22-2.94) for BMI of 20.0 to 24.9 kg/m(2). The increase in fracture risk per unit decrease in BMI was significantly greater among lean women than among overweight women (p physical inactivity was associated with an increased risk of hip fracture. There was no significant interaction between the relative effects of BMI and physical activity. For women who reported that they took any exercise versus no exercise, the adjusted relative risk of hip fracture was 0.68 (95% CI 0.62-0.75), with similar results for strenuous exercise. In this large cohort of postmenopausal women, BMI and physical activity had independent effects on hip fracture risk. Copyright © 2011 American Society for Bone and Mineral Research.

    The aims of the current study were to (1) determine the association between personal income and body mass index (BMI) and between individual education and BMI, and (2) examine the association between education and BMI across strata of personal income among women. The design of the study was a quantitative analysis of data from self-report questionnaires. The study setting was socioeconomically disadvantaged neighborhoods in Victoria, Australia. The study included 4065 nonpregnant women (ages 18-45 years) living in socioeconomically disadvantaged areas. The study used a self-report questionnaire measuring sociodemographic characteristics known to be associated with BMI. Multiple linear regressions with imputation were used to assess the association between education level, personal income, and BMI, while controlling for covariates. Mean (SD) observed BMI was 26.0 (6.1) kg/m2. Compared with women with low education, women with medium (b = -0.81; 95% confidence interval, -1.30 to -0.27; p = .004) and high (b = -1.71; 95% confidence interval, -2.34 to -1.09; p education had statistically significantly lower BMI values. No differences in BMI were observed between income categories. Stratified analyses suggested that the education-BMI association may be stronger in low-income than higher-income women. Our data show that among women living in socioeconomically disadvantaged areas, high education level rather than personal income may be protective against overweight/obesity. High personal income, however, may buffer the effects of low education on BMI. Obesity prevention efforts should target women with amplified disadvantage.

    Most previous research efforts have focused on the psychological effects of receiving a cancer diagnosis rather than the period of waiting for definitive Results. Early detection of cancer is directly linked to successful treatment regimes, yet these procedures evoke significant anxiety in patients. The long wait for medical test Results in state health institutions, with one of the possible outcomes being a cancer diagnosis, means that the days of waiting can induce emotional distress before the diagnosis has even been given. Eight research collaborators were invited to, in their own voice, shed light on their individual experiences while waiting for their biopsy Results to gain an understanding of the experiences of each collaborator by letting her tell her story and to explore the possibility of shared experience between collaborators. Research collaborators at a local, government hospital kept a journal for the two-week waiting period for their biopsy Results. Shortly before receiving their Results, they took part in a short semi-structured interview to inquire about their waiting. The theoretical framework used for data interpretation is critical theory focusing on the structures within society and healthcare systems that impact on the experience of waiting. The undercurrent of critical commentary about the roles of the gender, economic, political and cultural factors that contribute to the screening experience for women in South Africa helps to shed light on the complex forces at play within the procedures. The Results indicate that for some women waiting provokes significant psychological stress which manifests in multiple psychological processes including the psychological bracing phenomenon, denial, suppression and negation of their emotional experience all perpetuated by the structures of power within the health care system. More understanding of the psychological experience of awaiting a cancer diagnosis is required and there is an important place for

    Consideration of gender in the disaster sphere has centred almost exclusively on the vulnerability and capacities of women. This trend stems from a polarised Western understanding of gender as a binary concept of man-woman. Such an approach also mirrors the dominant framing of disasters and disaster risk reduction (DRR), emphasising Western standards and practices to the detriment of local, non-Western identities and experiences. This paper argues that the man-woman dichotomy is an insufficient construct with which to address the gendered dimensions of a disaster as it fails to capture the realities of diverse gender minorities in non-Western contexts. The paper presents case studies from the Philippines, Indonesia, and Samoa, where gender minorities display specific patterns of vulnerability associated with their marginal positions in society, yet, importantly, also possess a wide array of endogenous capacities. Recognition of these differences, needs, skills, and unique resources is essential to moving towards inclusive and gender-sensitive DRR. © 2017 The Author(s).

  1. Source criticism and cultural models: constructing life histories of women missionaries

    Full Text Available Research work is an interpretive enterprise. The variety of sources poses some central methodological questions for constructing religious life histories. There is an apparent discrepancy between the source categories concerning the content of the information. Private diaries and letters provide information on women's work and life which is not available in official reports and letters. They reveal dates, events and individuals which are not mentioned elsewhere. In histography the question of discrepancy is normally solved by comparing the sources with an aim to arrive at the "true picture" of how things have been. Such a picture is believed to portray not only the true life situation of the individual or group in question but, depending on the nature of the data, also the epoch and time situation itself. From the viewpoint of social sciences and comparative religion one will ask: could the variety of sources be approached and utilized in some other way? The second question posed by the data concerns the content of each source category. The information can be located on the continuum "highly subjective — stereotyped". Subjective information, including reflections on personal experiences may not be the best source e.g. for constructing the flow of historical events, but it is of uttermost importance if we want to show how individuals respond to social constraints and actively assemble social worlds.

    Full Text Available Obwohl die meisten deutschen Großstädte über eine sehr schlechte Radverkehrsinfrastruktur verfügen, gewinnent innerstädtisches Radfahren und ein Engagement für das Rad als gleichberechtigtes Verkehrsmittel stark an Bedeutung. Als Indiz für dieses Engagement gelten in Hamburg die monatlichen Critical Mass Radfahrten unter dem Motto „We aren’t blocking traffic… we are traffic!“. Der Beitrag fragt vor diesem Hintergrund, inwiefern die Critical Mass als Aktionsform in Hamburg den Diskurs der autogerechten Stadt, die Straßenverkehrspolitik und die dominante räumliche Ordnung in Frage stellen kann und ob die Critical Mass als performative Kritik der normativen Ordnung im Sinne Judith Butlers verstanden werden kann.

    Bone mineral density has a strong genetic component but it is also influenced by environmental factors making it a complex trait to study. LRP5 gene was previously shown to be involved in rare diseases affecting bone mass. Mutations associated with gain-of-function were described as well as loss-of-function mutations. Following this discovery, many frequent LRP5 polymorphisms were tested against the variation of BMD in the normal population. Heel bone parameters (SOS, BUA) were measured by right calcaneal QUS in 5021 healthy French-Canadian women and for 2104 women, BMD evaluated by DXA at two sites was available (femoral neck (FN) and lumbar spine (LS)). Among women with QUS measures and those with DXA measures, 26.5% and 32.8% respectively were premenopausal, 9.2% and 10.7% were perimenopausal and 64.2% and 56.5% were postmenopausal. About a third of the peri- and postmenopausal women never received hormone therapy. Two single nucleotide coding polymorphisms (Val667Met and Ala1330Val) in LRP5 gene were genotyped by allele-specific PCR. All bone measures were tested individually for associations with each polymorphism by analysis of covariance with adjustment for non genetic risk factors. Furthermore, haplotype analysis was performed to take into account the strong linkage disequilibrium between the two polymorphisms. The two LRP5 polymorphisms were found to be associated with all five bone measures (L2L4 and femoral neck DXA as well as heel SOS, BUA and stiffness index) in the whole sample. Premenopausal women drove the association as expected from the proposed role of LRP5 in peak bone mass. Our results suggest that the Val667Met polymorphism is the causative variant but this remains to be functionally proven.

    Full Text Available Background: The loss of muscle mass is associated with aging. The aim of this study was to determine the effects of resistance training and detraining on muscle mass in elderly women. Methods: Twenty post-menopausal women aged ≥50 years old were enrolled. Matching for age, they were randomly assigned into control and resistance training group (RT. The intervention consisted of three sets of 10 repetitions for 10 movements with Thera-Band tubing (based on 80-100% 10-RM, three times a week, for 12 weeks and thereafter, four weeks detraining. Skinfold thickness was determined by caliper. Percentage of body fat was estimated from skinfold thickness (triceps and subscapular by McArdle method. Fat mass (FM and fat-free mass (FFM were calculated. Range of motion for trunk flexion and extension was determined. Results: During 12 weeks of intervention, significant increases were observed in 1-RM of biceps curl, FFM, trunk flexion and extension and significant decreases during four weeks detraining in RT group. The RT group demonstrated significant decreases during resistance training and increases during detraining in skinfold thickness. FFM, trunk flexion, and extension decreased and skinfold thickness, %FM, and weight of body fat increased in the control group (P < 0.05. Conclusions: Resistance training with Thera-Band enhanced strength and muscle endurance in elderly women and a 4-week detraining period had an adverse effect on muscle power. This suggests that a strength training program is an effective intervention to prevent functional reductions, and can contribute to improve neuromuscular function in older adults.

    Full Text Available BACKGROUND: The measurement of adrenal and ovarian androgens in women with PCOS has been difficult based on poor specificity and sensitivity of assays in the female range. METHODS: Women with PCOS (NIH criteria; n = 52 and control subjects with 25-35 day menstrual cycles, no evidence of hyperandrogenism and matched for BMI (n = 42 underwent morning blood sampling. Liquid chromatography-tandem mass spectrometry (LC-MS/MS was used to simultaneously measure 13 steroids from a single blood sample to measure adrenal and ovarian steroids. Androgen and progesterone results were compared in the same samples using RIA. RESULTS: Testosterone, androstenedione, progesterone and 17OH progesterone levels were higher when measured using RIA compared to LC-MS/MS, although the testosterone RIA demonstrated the best agreement with the LC-MS/MS using a Bland-Altman analysis. Results using LC-MS/MS demonstrated that the concentration of androgens and their precursors were higher in women with PCOS than controls [median (2.5, 97.5th %ile; 1607 (638, 3085 vs. 1143 (511, 4784 ng/dL; p = 0.03]. Women with PCOS had higher testosterone [49 (16, 125 vs. 24 (10, 59 ng/dL], androstenedione [203 (98, 476 vs. 106 (69, 223 ng/dL] and 17OH progesterone levels [80 (17, 176 vs. 44 (17, 142 ng/dL] compared to controls (all P<0.02, but no differences in serum concentrations of the adrenal steroids DHEAS, cortisol, corticosterone and their 11 deoxy precursors. Women with PCOS also had an increase in the product:precursor ratio for 3β-hydroxysteroid dehydrogenase [22% (6, 92 vs. 20% (4, 43; p = 0.009]. CONCLUSION: LC-MS/MS was superior to RIA in measuring androstenedione, progesterone and 17OH progesterone levels, while testosterone measurements were better matched in the two assays. Androgen levels were higher in women with PCOS in the absence of a difference in adrenal-predominant steroids. These data support previous findings that the ovary is an important source

    Antenatal care has several benefits for expecting mothers and birth outcomes; yet many mothers do not utilise this service in Nepal. Mass media may play an important role in increasing the use of antenatal care and other maternal health services. However, the effect of mass media on increasing health service utilisation has remained an under studied area in Nepal. The aim of this study was to investigate the impact of mass media on the utilisation of antenatal care services in rural Nepal. A community-based cross-sectional study was conducted in Sinurjoda Village Development Committee of Dhanusha District, Nepal. A total of 205 mothers of children aged under 1 year were selected using systematic random sampling. Logistic regression was employed to examine the association between selected antenatal care services and mass media exposure after adjusting for other independent variables. A majority of mothers were exposed to mass media. Radio was accessible to most (60.0%) of the participants followed by television (43.41%). Mothers exposed to mass media were more likely to attending antenatal visits [Odds ratio (OR) 6.28; 95% CI (1.01-38.99)], taking rest and sleep during pregnancy [OR 2.65; 95% CI (1.13-6.26)], and receiving TT immunization [OR 5.12; 95% CI (1.23-21.24)] than their non-exposed counterparts. The study reported a positive influence of mass media on the utilisation of antenatal care services in Nepal. Therefore, further emphasis should be given to increase awareness of women of rural Nepal through mass media to improve utilisation of antenatal care services in Nepal.

    We report a combined study of the specific heat and de Haas-van Alphen effect in the iron-pnictide superconductor BaFe2(As(1-x)P(x))2. Our data when combined with results for the magnetic penetration depth give compelling evidence for the existence of a quantum critical point close to x=0.30 which affects the majority of the Fermi surface by enhancing the quasiparticle mass. The results show that the sharp peak in the inverse superfluid density seen in this system results from a strong increase in the quasiparticle mass at the quantum critical point.

    Objective The present study examined nutritional status and dietary intake of pregnant women in Japan in relation to pre-pregnancy body mass index (BMI).Methods Participants included 141 Japanese women with singleton pregnancies, from the outpatient department of the S hospital, Gunma prefecture, Japan. Two-day food records, dietary assessment questionnaires, and clinical records were obtained at 20 weeks gestation. Nine patients were excluded from the study due to morning sickness. The remaining 132 participants were divided into 3 groups according to pre-pregnancy BMI: underweight, normal weight, and overweight. Nutritional status and dietary intake were analyzed in relation to BMI using the chi-square test, Fisher's exact test, Kruskal-Wallis test, one-way analysis of variance, and analysis of covariance with adjustment for age, employment status, and total energy intake.Results Women who were underweight before pregnancy were more frequently working full-time than normal weight and overweight women. Underweight women were also more frequently anemic (P=0.038, underweight 39.3%, normal weight 24.7%, overweight 0%) and had lower mean hemoglobin (Hb) (P=0.021, underweight 11.3 g/dL, normal weight 11.6 g/dL, overweight 12.1 g/dL) and hematocrit (Hct) levels (P=0.025, underweight 33.7%, normal weight 34.3%, overweight 36.0%). Their dietary intake of protein, iron, magnesium, and folic acid was lower than that of normal weight and overweight women. Their meals tended to include fewer meat, fish, egg, and soybean dishes (underweight, mean of 4.7 servings per day; normal weight, 6.1 servings; overweight, 6.1 servings).Conclusion Pregnant women who were underweight before pregnancy had increased risk of anemia as well as reduced Hb and Hct levels. They had lower dietary intake of protein, iron and folic acid compared to women in the other BMI categories. Anemia and these nutrient deficiencies are known risk factors for low birth weight. Our findings suggest

    The relationships between calcaneal bone mass and dietary/lifestyle habits in women at 3-4 months postpartum were examined in the context of osteoporosis prevention. Cross-sectional survey. We measured bone mass using calcaneal ultrasound in mothers who brought their 3- to 4-month-old babies to healthcare centers in Japan for health examination and administered a self-report questionnaire on physical characteristics and dietary/lifestyle habits to those who agreed to participate in the survey. Valid data were available for 1220 women (valid response rate, 97.5%). Based on their stiffness score, a measure of bone mass, 70.9% (n = 865) of the participants were classified as 'no apparent abnormality (stiffness score ≥78.8)' (low-risk group), 18.2% (n = 222) as 'guidance required (≥70.1-healthy eating habits, such as increased consumption of calcium-rich foods, and prevent osteoporosis.

Little is known about attending psychiatric disorders in patients with gynecologic and other malignant diseases like cervical or breast cancer. However, patients suffering from other types of gynecologic cancer (eg, genital/cervical cancer may also have an increased risk of psychiatric symptoms. In this review, we identify the potential information deficits in this field. A two-rater independent literature search was conducted using the PubMed/Google Scholar search engines to systematically evaluate the literature on the research objectives, followed by a critical reflection on the results. Of the 77 screened studies, 15 met the criteria for inclusion in this review. Patients with gynecologic malignancies, especially cervical cancer, had a very high prevalence of psychiatric symptoms including depression (33%–52%. Additionally, the risk groups facing higher rates of concomitant reduced quality of life and increased psychiatric symptoms such as depression were identified. Specifically, low socioeconomic status, sexual inactivity, absence of a partner, and physical symptoms were correlated with an increased risk. Patients

    Fat-free mass (FFM) is lower in obese subjects with Prader-Willi syndrome (PWS) than in obese subjects without PWS. FFM prediction equations developed in non-PWS subjects may, thus, not work in PWS subjects. To test whether the estimation of FFM from bioelectrical impedance analysis (BIA) in PWS subjects requires population-specific equations. Using dual-energy X-ray absorptiometry, this study measured FFM in 27 PWS and 56 non-PWS obese women and evaluated its association with the impedance index at 50 kHz (ZI50), i.e. the ratio between squared height and whole-body impedance at 50 kHz. At the same level of ZI50, PWS women had a lower FFM than non-PWS women. However, when PWS-specific equations were used, FFM was accurately estimated at the population level. An equation employing a dummy variable coding for PWS status was able to explain 85% of the variance of FFM with a root mean squared error of 3.3 kg in the pooled sample (n = 83). Population-specific equations are needed to estimate FFM from BIA in obese PWS women.

It is supposed that both study groups may have difference in work pressures with resultant diverse preferences for food. This can affect health status particularly in relation to obesity in women. Furthermore, we selected participants with 14 years education expecting basic awareness of healthful diet. Methods: This cross sectional study had a convenient sampling method and sample size of 600 with 300 house wives and 300 working women, aged 35-45 years. Dietary habits were recorded by interview. BMI was calculated by standard formula, and results obtained by Chi-Square using SPSS 17. Results: Working women had healthier dietary practices. Number of meals, fruits, fish/ poultry and water consumption was better in working mothers with significant p value < 0.00.1. Intake of vegetables and fast food was found similar. BMI comparison showed that majority of housewives were noted as overweight whereas working women showed normal weight, p-value=< 0.001. Most housewives responded that they have a sedentary life style as opposed to working women p- value < 0.001. Self- assessment of diet quality was comparable as it was mentioned moderate by most of the participants, however more working females accepted that they need to improve their diet and would need expert advice. Conclusion:Healthier BMI, active life style and better dietary habits were witnessed in working women as compared to housewives. (author)

    Extreme weather often contributes to crown fires, where the fire spreads from one tree crown to the next as a series of piloted ignitions. An important aspect in predicting crown fires is understanding the ignition of fuel particles. The ignition criterion considered in this work is the critical mass flux criterion – that a sufficient amount of pyrolysis gases must be...

    Relationships between muscular strength and arterial stiffness as well as between muscle mass and arterial stiffness have been observed suggesting a link between the neuromuscular system and vascular health. However, the relationship between central arterial stiffness and absolute and relative strength along with muscle mass has not been investigated in both sexes across a broad age range. The purpose of this study was to examine the relationship between central arterial stiffness and absolute and relative strength as well as between central arterial stiffness and lean body mass (LBM) in men and women across a broad age range. LBM, central arterial stiffness and strength were measured on 36 men and 35 women between the ages of 18 and 75 years. Strength was measured on five machine resistance exercises and summed as one measure of overall strength (absolute strength). Relative strength was calculated as total strength divided by LBM (relative strength). Central arterial stiffness was inversely related to both absolute (r = -0·230; P = 0·029) and relative strength (r = -0·484; P LBM (r = 0·097; P = 0·213). The relationship between central arterial stiffness and relative strength was attenuated but still present when controlling for either age, per cent body fat, LBM or mean arterial pressure. These results suggest that, across a wide age range, the expression of relative muscular strength has a stronger relationship with central arterial stiffness compared to either LBM or absolute strength. This suggests that muscle function more than muscle mass may be coupled with vascular health. © 2017 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    A large amount of epidemiological evidence suggests that the impact of body weight on breast cancer risk should be heterogeneous throughout the life-stage of women. At birth, high weight has been positively associated with an increased risk of breast cancer. While, the body mass index (a relative body weight; BMI kg/m{sup 2}) has been inversely associated with breast cancer risk among pre-menopausal women. The inverse trend had been observed in both Western and Asian population, with a relatively lower percentage of obesity and higher percentage of leanness, suggested that the inverse trend could be explained not only by the protective impact due to obesity, but also by the increased risk of breast cancer due to leanness. Among post-menopausal women, however, an elevated BMI has been positively associated with the development of breast cancer, particularly in the cases of estrogen receptor-positive (ER+) and progesterone receptor-positive (PR+) tumors. Currently, the mechanisms underlying the heterogeneous impacts between BMI on breast cancer risk and the life-stage of women remain poorly understood. We reviewed several proposed biological mechanisms that may contribute to the various impacts of relative body weight on breast cancer risk across life-stage. We also discussed the impact of BMI upon the outcome of endocrine therapy, particularly for aromatase inhibitor, in breast cancer patients. To prevent breast cancer incidence and recurrence, the desirable BMI of women may differ throughout their life-stage. To define the underlying mechanism for the various impacts of BMI in the context of breast cancer across various female life stages, further studies will be required.

    Exposure to mass media provides increased awareness and knowledge, as well as changes in attitudes, social norms and behaviors that may lead to positive public health outcomes. Birth preparedness (i.e. the preparations for childbirth made by pregnant women, their families, and communities) increases the use of skilled birth attendants (SBAs) and hence reduces maternal morbidity and mortality. The aim of this study was to explore the association between media exposure and birth preparedness in rural Uganda. A total of 765 recently delivered women from 120 villages in the Mbarara District of southwest Uganda were selected for a community-based survey using two-stage cluster sampling. Univariate and multivariate logistic regression was performed with generalized linear mixed models using SPSS 21. We found that 88.6% of the women surveyed listened to the radio and 33.9% read newspapers. Birth preparedness actions included were money saved (87.8%), identified SBA (64.3%), identified transport (60.1%), and purchased childbirth materials (20.7%). Women who had taken three or more actions were coded as well birth prepared (53.9%). Women who read newspapers were more likely to be birth prepared (adjusted OR 2.2, 95% CI 1.5-3.2). High media exposure, i.e. regular exposure to radio, newspaper, or television, showed no significant association with birth preparedness (adjusted OR 1.3, 95% CI 0.9-2.0). Our results indicate that increased reading of newspapers can enhance birth preparedness and skilled birth attendance. Apart from general literacy skills, this requires newspapers to be accessible in terms of language, dissemination, and cost.

    The study objective was to evaluate the realization of the reducing diet recommended in the treatment of overweight or obesity (1500 kcal) with regard to the caloric value and the content of basic nutrients, vitamins and bioelements. The study was conducted on a group of 48 women. Daily food rations were evaluated based on a week's dietary register. Results were averaged in each patient and compared to the norms worked out by the Institute of Food and Feeding in Warsaw for subjects with low physical activity. The mean energetic value of the diets was found to meet the requirements. Approximately 50% of the obese women consumed high-protein, low-fat and low-carbohydrate food rations. The analysis of vitamin content in daily food rations showed insufficient intake of vitamin E (in 89.6% of women), thiamin (83.3%), riboflavin (93.7%), niacin (60.4%), vitamin B6 (87.5%), folic acid (89.6%) and vitamin C (72.9%). Vitamin A intake was higher than the recommended norm in 47.9% of women. The lowest realization was noted in the case of potassium (64.6% of rations below the norm), calcium (100% below the norm), magnesium (64.6% below the norm). However, dietary sodium and phosphate content in most obese women exceeded the norms. The intake was too low in the case of iron (in 91.7%), zinc (in 97.9%) and copper (in 100%). It seems that long-term compliance with such a diet requires additional individual supplementation.

    To investigate the impact of multiple pregnancies on postmenopausal bone mineral density (BMD). BMD at the femoral neck (FN) and lumbar spine (LS) was measured by dual energy X-ray absorptiometry (DXA) method. Diagnosis of osteoporosis (OP) was confirmed by World Health Organization criteria. Women were stratified according to number of parity as 7 parity groups as well as in age groups of or = 65 years. BMD values and frequency of OP were compared across the groups according to age. Multiple logistic regression analysis with calculation of adjusted odds ratio (OR) was used for association. A total of 264 women with mean age of 63 +/- 8.7 and mean menopausal duration of 15.8 +/- 10.2 years were studied. LS-OP and FN-OP were observed in 28% and 58.3% of women, respectively. There were significant differences in BMD values across different parity groups at both sites of LS and FN (p = 0.011 and p = 0.036, respectively). Parity 4-7 (vs. 7 significantly decreased LS-BMD and FN-BMD as compared with 0-7 parity (p = 0.006 and p = 0.009, respectively). Parity > 7 increased the risk of LS-OP by OR = 1.81 (95% CI 1.03-3.1, p = 0.037) and FN-OP by OR = 1.67 (95% CI 0.97-2.8, p = 0.063). In addition, women with high parity had lower BMD decline at LS and FN by age (> or = 65 vs. 7 is associated with spinal trabecular bone loss in younger postmenopausal women as well as an osteoprotective effect against age-related bone loss, which counteracts the early negative effect. Therefore, parity should not be considered as a risk factor for postmenopausal osteoporosis.

    Powder sintering was used to produce homogeneous type oxide ceramics of Pu with Hf, Gd and Li 6 . In all the ceramics, there is the number of neutron poison (Hf, Gd and Li) atoms per plutonium atom needed, according to the physical calculation, for them to be free of critical mass. PuO 2 stabilizers high-temperature modifications of cubic HfO 2 or hexagonal Gd 2 O 3 , however, at the ratio given by the physical calculation, the plutonium is insufficient for their full stabilization. Addition of yttrium oxide as an additive stabilizing the fcc phase of HfO 2 resulted in cubic solid solution (Pu, Hf, Y)O 2-x . Pu/Li/Hf and Pu/Li/Si ceramics produced by sintering of PuO 2 and compound Li 2 HfO 3 or 6 Li 4 SiO 4 powders is characterized with presence of two phases. The method of differential thermal analysis demonstrated the phase stability of (Pu-Hf, Pu-Gd, Pu-Li-Hf) oxide ceramics in the 20-1500degC temperature range. Ceramic (Pu/Li/Si) has several endothermal effects. Tests in boiling water solutions of various composition suggest that the specimens of Pu, Hf oxides and ternary oxides (Pu, Hf, Y)O 2 are less stable in weakly acidic media than in weakly alkaline medium and distilled water. The obtained results were used as a basis to estimate the assumed solid solution region boundaries for binary Hf, Pu and ternary Hf, Pu, Y oxides on the side of HfO 2 . (author)

    To study the prevalence of metabolic syndrome (MBS) in Indian women and to see how does it correlate to body mass index (BMI) and polycystic ovarian syndrome (PCOS) in this population. Prospective cross-sectional observational study. Infertility clinic of a tertiary center. Two hundred women, 120 with PCOs and 80 age-matched controls were enrolled. The prevalence of MBS was studied in the women with and without and was co related to BMI by further subgrouping as team (BMI 23 kg/m2). The sample size was: team controls-40, obese controls-40, team PCOS-80. Each subject underwent a physical examination and laboratory evaluation for the diagnosis of MBS, which was defined according to the guidelines of National Cholesterol Education Program Adult Treatment Pamel (NCEP ATP III) 2005. None. Subjects with and without PCOs were compared with each other for the prevalence of MBS, and similarly team subjects were compared with obese subjects. Receiver operator characteristic (ROC) curves were obtained for both the PCOS and non PCOS population separately, co-relating the prevalence of MBS with BMI. These ROC curves were used to establish the cut off values of BMI, which could best predict the risk of MBS. The prevalence of MBS was significantly higher in the women with PCOS, as compared to age-matched controls. Similarly, when BMI was considered, MBS was more prevalent in overweight subjects than in lean subjects with or without PCOS. In subgroup analysis, the presence of PCOS had a lesser impact on the prevalence of MBS as compared to non-PCOS controls with higher BMI. The relative risk of MBS increased as follows: lean controls-1, lean PCOS-2.66, obese controls-5.33, and obese PCOS-6.5. The most appropriate cut-off level of BMI for predicting the risk of MBS in Indian women without PCOS seems to be 23 kg/m(2), whereas, with PCOS, it was 22.5 kg/m(2). MBS is more prevalent in women with PCOS. However, obesity is an independent and stronger risk factor for developing MBS. To

    Background Advice on fibromyalgia, a chronic illness primarily affecting women, often presents it as incompatible with work and rarely covers how to remain employed. Yet many women do. Objectives We aimed to understand how these women, their family members, and workmates portrayed employees with fibromyalgia, and how these portrayals helped women retain employment. Methods We interviewed 22 participants, comprising five triads and three dyads of people who knew each other. Using the methodology of critical discourse analysis, we analysed the interview data within and across the triads/dyads through coding, narrative summaries, and relational mapping. Results Participants reported stereotypes that employees with fibromyalgia are lazy, malingering, and less productive than healthy workers. Countering these assumptions, participants portrayed the women as normal, valuable employees who did not 'give in' to their illness. The portrayals drew on two discourses, normalcy and mind-controlling-the-body, and a related narrative, overcoming disability. We propose that participants' portrayals helped women manage their identities in competitive workplaces and thereby remain employed. Discussion Our findings augment the very sparse literature on employment with fibromyalgia. Using a new approach, critical discourse analysis, we expand on known job-retention strategies and add the perspectives of two key stakeholders: family members and workmates.

  10. An ecological framework for sexual minority women's health: factors associated with greater body mass.

    In recent years, many studies have focused on the body of sexual minority women, particularly emphasizing their larger size. These studies rarely offer theoretically based explanations for the increased weight, nor study the potential consequences (or lack thereof) of being heavier. This article provides a brief overview of the multitude of factors that might cause or contribute to larger size of sexual minority women, using an ecological framework that elucidates upstream social determinants of health as well as individual risk factors. This model is infused with a minority stress model, which hypothesizes excess strain resulting from the stigma associated with oppressed minority identities such as woman, lesbian, bisexual, woman of color, and others. We argue that lack of attention to the upstream social determinants of health may result in individual-level victim blaming and interventions that do not address the root causes of minority stress or increased weight.

    A growing body of literature supports the association between adverse stress experiences and health inequities, including obesity, among African American/Black women. Adverse stress experiences can contribute to poor appetite regulation, increased food intake, emotional eating, binge eating, and sedentary behavior, all of which can contribute to weight gain and obesity. Most research studies concerning the effect of psychological stress on eating behaviors have not examined the unique stress experience, body composition, and eating behaviors of African American/Black women. Even fewer studies have examined these constructs among Black female college students, who have an increased prevalence of overweight and obesity compared to their counterparts. Therefore, the aim of the current study is to examine the associations among emotional eating, perceived stress, contextualized stress, and BMI in African American female college students. All participants identified as African American or Black (N=99). The mean age of the sample was 19.4 years (SD=1.80). A statistically significant eating behavior patterns×perceived stress interaction was evident for body mass index (BMI) (β=0.036, S.E.=.0118, pstress interaction was observed for BMI (β=0.007, S.E.=.0027, p=.015). Findings from this study demonstrate that the stress experience interacts with emotional eating to influence BMI. Based on these findings, culturally relevant interventions that target the unique stress experience and eating behavior patterns of young African American women are warranted. Copyright © 2015.

    The aging process is associated with the development of several diseases, which can be attenuated by the practice of physical activities. Aerobic training is an effective method to maintain and improve cardiovascular function. Additionally, it has a crucial role in the prevention and treatment of several chronic-degenerative diseases, especially diabetes mellitus. } To verify the effect of a 13-week aerobic training program on blood pressure (BP), body mass index (BMI) and glycemia levels in elderly women with type-2 diabetes mellitus (DM2). Eleven sedentary elderly women with DM2, aged 61.0 ± 9.1 years, were submitted a 13-week aerobic training program, constituting group G2. Eleven controlled elderly women (aged 60.2 ± 6.8 years) were not submitted to the aerobic training, constituting the control group (G1). G1 attended educational lectures once a week, whereas G2 walked three times a week. Both groups presented a significant decrease in glycemia and diastolic blood pressure levels. No significant decreases in BMI were observed after the aerobic training in either group. The 13-week aerobic training program was enough to promote significant decrease in the diastolic blood pressure and glycemia levels; therefore, this type of exercise training decreases the risk factors for cardiovascular and metabolic diseases.

    Full Text Available We studied if testosterone and estradiol concentrations are associated with specific female waist-to-hip ratios (WHRs and body mass indices (BMIs. Participants were 187 young women from which waist, hips, weight, and height were measured. In addition, participants informed on which day of their menstrual cycle they were and provided a 6 mL saliva sample. Ninety-one of them were in the follicular phase and 96 in the luteal phase. Only in the fertile phase of the menstrual cycle we found a significant interaction between testosterone and estradiol affecting WHR (b±s.e.=-0.000003±0.000001; t94=-2.12, adjusted R2=-0.008, P=0.03. Women with the highest levels of both hormones had the lowest WHRs, while women with low estradiol and high testosterone showed the highest WHRs. BMI significantly increased as testosterone increased in female in their nonfertile days.

    Full Text Available Background. Malaria during pregnancy is a major public health problem in Nigeria especially in malaria-endemic areas. It increases the risk of low birth weight and child/maternal morbidity/mortality. This paper addresses the impact of radio campaigns on the use of insecticide-treated bed nets among pregnant women in Nigeria. Methods. A total of 2,348 pregnant women were interviewed during the survey across 21 of Nigeria’s 36 states. Respondents were selected through a multistage sampling technique. Analysis was based on multivariate logistic regression. Results. Respondents who knew that sleeping under ITN prevents malaria were 3.2 times more likely to sleep under net (OR: 3.15; 95% CI: 2.28 to 4.33; P<0.0001. Those who listened to radio are also about 1.6 times more likely to use ITN (OR: 1.56; 95% CI: 1.07 to 2.28; P=0.020, while respondents who had heard of a specific sponsored radio campaign on ITN are 1.53 times more likely to use a bed net (P=0.019. Conclusion. Pregnant women who listened to mass media campaigns were more likely to adopt strategies to protect themselves from malaria. Therefore, behavior change communication messages that are aimed at promoting net use and antenatal attendance are necessary in combating malaria.

    Few intervention studies have used whole-body vibration (WBV) training in the elderly, and there is inconclusive evidence about its health benefits. We examined the effect of 8 months of WBV training on muscle mass and functional capacity in elderly women. A total of 37 women (aged 82.4 ± 5.7 years) voluntarily participated in this study. Subjects were randomly assigned to a vibration group (n = 19) or a control group (n = 18). The vibration group trained on a vertical vibration platform twice a week. The control group was requested not to change their habitual lifestyle. The quadriceps femoris muscle cross-sectional area was determined by magnetic resonance imaging. All participants were evaluated by a battery of tests (Senior Fitness Test) to determine their functional capacity, as well as handgrip strength and balance/gait. General linear repeated-measure analysis of variance (group by time) was performed to examine the effect of the intervention on the outcomes variables. After 8 months, nonstatistically significant differences in the quadriceps CSA (pre-training: 8,516.16 ± 1,271.78 mm² and post-training: 8,671.63 ± 1,389.03 mm²) (p > 0.05) were found in the WBV group (Cohen's d: -0.12), whereas the CON group significantly decreased muscle mass (pre-training: 9,756.18 ± 1,420.07 mm² and post-training: 9,326.82 ± 1,577.53 mm²), with moderate effect size evident (Cohen's d: 0.29). In both groups, no changes were observed in the functional capacity, handgrip strength and balance/gait. The WBV training could prevent the loss of quadriceps CSA in elderly women.

    Spatial patterns in vegetation long have been used to scale both landsurface-atmosphere exchanges of water and carbon as well as to infer subsurface structure. These pursuits typical proceed in isolation and rarely do inferences gained from one community propagate to related efforts in another. Perhaps more importantly, vegetation often is treated as an emergent property of landscape-climate interactions rather than an active modifier of both critical zone structure and energy fluxes. We posit that vegetation structure and activity are under utilized as a tool towards understanding landscape evolution and present examples that begin to disentangle the role of vegetation as both an emergent property and an active control on critical zone structure and function. As climate change, population growth, and land use changes threaten water resources worldwide, the need for the new insights vegetation can provide becomes not just a basic science priority, but a pressing applied science question with clear societal importance. This presentation will provide an overview of recent efforts to address the dual role of vegetation in both modifying and reflecting critical zone structure in the western North American forests. For example, interactions between topography and stand scale vegetation structure influence both solar radiation and turbulence altering landscape scale partitioning of evaporation vs transpiration with major impacts of surface water supply. Similarly, interactions between topographic shading, lateral redistribution of plant available water, and subsurface storage create a mosaic of drought resistance and resilience across complex terrain. These complex interactions between geophysical and vegetation components of critical zone structure result in predictable patterns in catchment scale hydrologic partitioning within individual watersheds while simultaneously suggesting testable hypotheses for why catchments under similar climate regimes respond so

    To evaluate changes in body mass index (BMI) and health-related quality of life (HRQoL), including an acne parameter, of overweight adult women with polycystic ovary syndrome (PCOS) during a lifestyle modification program. Prospective longitudinal within-patient study. Department of Reproductive Medicine of the Ghent University Hospital (Belgium). Thirty-three overweight (BMI ≥ 25 kg/m²) women with PCOS between age 18 and 43 years. Participants followed a 24-week lifestyle modification program consisting of a diet, exercise, and psychological subprogram. BMI was assessed at Weeks 0, 8, 16, and 24 of the program. The HRQoL was measured at Week 0, 12, and 24 of the program using the PolyCystic Ovary Syndrome Questionnaire (PCOSQ) and a Visual Analogue Scale (VAS) to evaluate the influence of acne on HRQoL. During a 24-week period no significant decrease in BMI occurred (mean difference = 1.71, 95% confidence interval [CI] [-1.38, 4.81]. During that period, there was a significant positive evolution of the total PCOSQ score, F(2, 37.5) = 23.7, the emotions, F(2, 37.9) = 4.2, weight, F(2, 42.1) = 24.8, body hair, F(2, 35.6) = 3.3, and infertility problems domain scores, F(2, 43.1) = 15.64, of the PCOSQ, as well as of the acne VAS score, F(2, 29.3) = 4.2. These effects primarily occurred during the first 12 weeks. In spite of no significant changes in BMI, the HRQoL of overweight adult women with PCOS significantly improved during a 24-week lifestyle modification program. © 2015 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Low body mass index (BMI) is a well-established risk factor for fracture in postmenopausal women. Height and obesity have also been associated with increased fracture risk at some sites. We investigated the relationships of weight, BMI, and height with incident clinical fracture in a practice-based cohort of postmenopausal women participating in the Global Longitudinal study of Osteoporosis in Women (GLOW). Data were collected at baseline and at 1, 2, and 3 years. For hip, spine, wrist, pelvis, rib, upper arm/shoulder, clavicle, ankle, lower leg, and upper leg fractures, we modeled the time to incident self-reported fracture over a 3-year period using the Cox proportional hazards model and fitted the best linear or nonlinear models containing height, weight, and BMI. Of 52,939 women, 3628 (6.9%) reported an incident clinical fracture during the 3-year follow-up period. Linear BMI showed a significant inverse association with hip, clinical spine, and wrist fractures: adjusted hazard ratios (HRs) (95% confidence intervals [CIs]) per increase of 5 kg/m(2) were 0.80 (0.71-0.90), 0.83 (0.76-0.92), and 0.88 (0.83-0.94), respectively (all p fractures, linear weight showed a significant positive association: adjusted HR per 5-kg increase 1.05 (1.02-1.07) (p fractures, only linear height was significantly associated: adjusted HRs per 10-cm increase were 0.85 (0.75-0.97) (p = 0.02) and 0.73 (0.57-0.92) (p = 0.009), respectively. For pelvic and rib fractures, the best models were for nonlinear BMI or weight (p = 0.05 and 0.03, respectively), with inverse associations at low BMI/body weight and positive associations at high values. These data demonstrate that the relationships between fracture and weight, BMI, and height are site-specific. The different associations may be mediated, at least in part, by effects on bone mineral density, bone structure and geometry, and patterns of falling. © 2014 American Society for Bone and Mineral Research.

    Gynecological examination and transvaginal ultrasound are difficult or impossible in girls and young women who have not started their sexual life. CT is not a method of choice in this age group because of the ionizing radiation and iodine-containing contrast media. MRI is chosen then. Pelvic MRI was performed in 15 patients aged 9-19 years with suspected ovarian mass after they had had unclear gynecological and sonographic examinations. 1.5 T MRI systems were used. SE,T(F)SE and SPIR sequences were applied in T1- and T2-weighted images in three planes. Contrast media were administered in 7 patients. In a group of 3 girls with acute abdominal pain, polycystic ovaries, ovarian hemorrhagic cyst, and fibroma of the ovary were diagnosed. In a group of 11 patients with chronic abdominal pain, dermoid cysts of the ovaries were found in 7 cases, in one bilateral and accompanied by ectopic kidney. In 2 patients, serous cysts were diagnosed. In 2 cases an ovarian origin of the mass was excluded: multilocular cystic lesion in the presacral region and a hydatid mole were revealed. A neoplastic ovarian mass was diagnosed in a girl with increasing circumference of the abdomen. The accuracy of MRI in localizing lesions was 100%. Its accuracy in precisely characterizing lesions was 83.3%. Magnetic resonance imaging, with its noninvasiveness, high spatial resolution, and tissue specificity, is a method of choice in the diagnosis or exclusion of ovarian pathology in children and adolescents.

    To examine the cut-off point of the osteoporosis self-assessment tool, age, weight and body mass index for osteoporosis among young adult Taiwanese women, using a large-scale health examination database containing bone mineral density tests. The cut-off points of osteoporosis risk factors identified earlier focus on menopausal or senior Caucasian and Asian women. However, young adult Asian women have seldom been identified. A retrospective historical cohort study. Using the 2009-2011 health examination database of a large-scale medical centre in northern Taiwan, this study investigated young adult Asian women (i.e. range in age from 30-49 years) in Taiwan who had received dual-energy X-ray absorptiometry test. This study also explored the cut-off point, sensitivity, specificity and diagnostic accuracy of receiver operating characteristics of osteoporosis among young adult females in Taiwan. This study collected 2454 young adult Asian women in Taiwan. Cochran-Armitage analysis results indicated that the prevalence of osteoporosis increased with decreasing weight, body mass index and osteoporosis self-assessment method quartiles. According to the results of receiver operating characteristics, weight, body mass index and osteoporosis self-assessment tool approaches can generally be used as indicators to predict osteoporosis among young adult Asian women. Results of this study demonstrate that Taiwanese women contracting osteoporosis tend to be young and underweight, as well as having a low body mass index and osteoporosis self-assessment scores. Those results further suggest that the assessment indicators for cut-off points are appropriately suitable for young adult women in Taiwan. Early detection is the only available means of preventing osteoporosis. Professional nurses should apply convenient and accurate assessment procedures to help young adult women to adopt preventive strategies against osteoporosis early, thus eliminating the probability of osteoporotic

    Critical and subcritical masses were calculated for a sphere of five curium isotopes from 243 Cm to 247 Cm in metal and in metal-water mixtures considering three reflector conditions: bare, with a water reflector or a stainless steel reflector. The calculation were made mainly with a combination of a continuous energy Monte Carlo neutron transport calculation code, MCNP, and the Japanese Evaluated Nuclear Data Library, JENDL-3.2. Other evaluated nuclear data files, ENDF/B-VI and JEF-2.2, were also applied to find differences in calculation results of the neutron multiplication factor originated from different nuclear data files. A large dependence on the evaluated nuclear data files was found in the calculation results: more than 10%Δk/k relative differences in the neutron multiplication factor for a homogeneous mixture of 243 Cm metal and water when JENDL-3.2 was replaced with ENDF/B-VI and JEF-2.2, respectively; and a 44% reduction in the critical mass by changing from JENDL-3.2 to ENDF/B-VI for 246 Cm metal. The present study supplied basic information to the ANSI/ANS-8.15 Working Group for revision of the standard for nuclear criticality control of special actinide elements. The new or revised values of the subcritical mass limits for curium isotopes accepted by the ANSI/ANS-8.15 Working Group were finally summarized. (author)

    Studies suggest that ACE-inhibitors (ACE-I) and angiotensin receptor blockers (ARBs) may preserve skeletal muscle with aging. We evaluated longitudinal differences in lean body mass (LBM) among women diagnosed with hypertension and classified as ACE-I/ARB users and nonusers among Women's Health Initiative participants that received dual energy X-ray absorptiometry scans to estimate body composition ( n =10,635) at baseline and at years 3 and 6 of follow-up. Of those, 2642 were treated for hypertension at baseline. Multivariate linear regression models, adjusted for relevant demographics, behaviors, and medications, assessed ACE-I/ARB use/nonuse and LBM associations at baseline, as well as change in LBM over 3 and 6 years. Although BMI did not differ by ACE-I/ARB use, LBM (%) was significantly higher in ACE-I/ARB users versus nonusers at baseline (52.2% versus 51.3%, resp., p =0.001). There was no association between ACE-I/ARB usage and change in LBM over time. Reasons for higher LBM with ACE-I/ARB use cross sectionally, but not longitundinally, are unclear and may reflect a threshold effect of these medications on LBM that is attenuated over time. Nevertheless, ACE-I/ARB use does not appear to negatively impact LBM in the long term.

Every subject was evaluated firstly with an original questionnaire to discover risk factors (like for example steroids consumption, recent fractures of the lower limb, then was measured by quantitative heel ultrasonometry Hologic Sahara. Results: Mean extimated Bone Mineral Density (BMD 0.588 g/cm2 (SD 0.124 mean Quantitative Ultrasound Index (QUI 105.0 (SD 19.6, mean Speed of Sound (SOS 1564.2 m/s (SD 31.4, mean Broadband Ultrasound Attenuation (BUA 84.8 dB/MHz (SD 17.4. No significant correlation was found between QUS parameters and anthropometric data. A correlation was found between every QUS parameters. No significant differences were found about QUI and extimated BMD, between our results and Hologic normative data for European women. Conclusions: It is very important to develop specific reference values for any measurement device and site of skeleton especially in the age of reaching the peak bone mass because the T score is then measured referring to these data. Usually the normative data are supplied by manufacturer and are based on large multicentric study. In our opinion it could be helpful to verify if these data are compatible with the population examined in every region.

    High physical activity level has been associated with high bone mass and low fracture risk and is therefore recommended to reduce fractures in old age. The aim of this study was to estimate the effect of potentially modifiable variables, such as physical activity, muscle strength, muscle mass and weight, on bone mass in elderly women. The influence of isometric thigh muscle strength, self-estimated activity level, body composition and weight on bone mineral density (dual energy X-ray absorptiometry; DXA) in total body, hip and spine was investigated. Subjects were 1004 women, all 75 years old, taking part in the Malmö Osteoporosis Prospective Risk Assessment (OPRA) study. Physical activity and muscle strength accounted for 1-6% of the variability in bone mass, whereas weight, and its closely associated variables lean mass and fat mass, to a much greater extent explained the bone mass variability. We found current body weight to be the variable with the most substantial influence on the total variability in bone mass (15-32% depending on skeletal site) in a forward stepwise regression model. Our findings suggest that in elderly women, the major fracture-preventive effect of physical activity is unlikely to be mediated through increased bone mass. Retaining or even increasing body weight is likely to be beneficial to the skeleton, but an excess body weight increase may have negative effects on health. Nevertheless, training in elderly women may have advantages by improving balance, co-ordination and mobility and therefore decreasing the risk of fractures.

    Full Text Available Introduction. Osteoporosis and osteopenia are related to changes in the quantity and quality of skeletal muscle and contribute to a decreased level of muscle strength. The purpose of this study was to evaluate the impact of Nordic walking training on muscle strength and the electromyographic (EMG activity of the lower body in women with low bone mass. Material and methods. The participants of the study were 27 women with low bone mass. The sample was randomly divided into two groups: a control group and an experimental group. Women from the experimental group participated in 12 weeks of regular Nordic walking training. Functional strength was assessed with a 30-second chair stand test. The EMG activities of the gluteus maximus (GMax, rectus femoris (RF, biceps femoris (BF, soleus (SOL, and lumbar (LB muscles were measured using a surface electromyogram. Results. Nordic walking training induced a significant increase in the functional strength (p = 0.006 of the lower body and activity of GMax (p = 0.013 and a decrease in body mass (p = 0.006 in women with reduced bone mass. There was no statistically significant increase in the EMG activities of the RF, BF, SOL, or LB muscles. The study did not indicate any significant changes in functional muscle strength, the EMG activity of the lower body, or anthropometry in women from the control group. Conclusions. Nordic walking training induces positive changes in lower body strength and the electromyographic activity of the gluteus maximus as well as a decrease in body mass in women with low bone mass.

    Evidence is emerging that obesiy and weight gain may affect the prognosis of several types of cancer. We investigated the impact of body mass index (BMI) as well as pre-and postdiagnosis weight changes on non-Hodgkin lymphoma (NHL) prognosis. A cohort of 573 female incident NHL cases diagnosed during 1996-2000 in Connecticut was followed for a median of 7.8 yr. Self-reported height and weight at 3 time points before and after diagnosis were collected. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using proportional hazard models adjusting for factors believed to be associated with overall survival of NHL. Underweight (BMI treatment were found to have a poorer survival.

    To determine whether the probability of having heard about human papillomavirus (HPV) vaccination differs by socio-demographic characteristics among Colombian women; and whether the effect of predictors of having heard about HPV vaccination varies by educational levels and rural/urban area of residence. Data of 53,521 women aged 13-49 years were drawn from the 2010 Colombian National Demographic and Health Survey. Women were asked about aspects of their health and their socio-demographic characteristics. A logistic regression model was used to identify factors associated with having heard about HPV vaccination. Educational level and rural/urban area of residence of the women were tested as modifier effects of predictors. 26.8% of the women had heard about HPV vaccination. The odds of having heard about HPV vaccination were lower among women: in low wealth quintiles, without health insurance, with subsidized health insurance, and those who had children (p<0.001). Although women in older age groups and with better education had higher probabilities of having heard about HPV vaccination, differences in these probabilities by age group were more evident among educated women compared to non-educated ones. Probability gaps between non-educated and highly educated women were wider in the Eastern region. Living in rural areas decreased the probability of having heard about HPV vaccination, although narrower rural/urban gaps were observed in the Atlantic and Amazon-Orinoquía regions. Almost three quarters of the Colombian women had not heard about HPV vaccination, with variations by socio-demographic characteristics. Women in disadvantaged groups were less likely to have heard about HPV vaccination. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    To investigate the relationship between skinfold thickness and body mass index (BMI) in North European Caucasian and East Asian young women with and without anorexia nervosa (AN) in two countries. Height, weight and skinfold thicknesses were assessed in 137 young women with and without AN, in Australia and Singapore. The relationship between BMI and the sum of triceps, biceps, subscapular and iliac crest skinfolds was analysed with clinical status, ethnicity, age and country of residence as covariates. For the same BMI, women with AN had significantly smaller sums of skinfolds than women without AN. East Asian women both with and without AN had significantly greater skinfold sums than their North European Caucasian counterparts after adjusting for BMI. Lower BMI goals may be appropriate when managing AN patients of East Asian ancestry and the weight for height diagnostic criterion should be reconsidered for this group.

After adjusting for confounders, women from East Asia were most likely to develop GDM (37, 24.0% and 5-fold more likely than women from ANZ (OR = 4.77, 95% CI: 3.12, 7.31, p<0.001. Women from other Asian countries had a 3-fold increased risk of GDM compared to women from ANZ. There was no evidence of an interaction by BMI (p=0.24.  Conclusions. Women born in Asia have higher risk of GDM compared to women born in ANZ. These data provide support for including COB in GDM management policies.

    The delivery of efficient nonpharmacological treatment to prevent the loss of muscle mass in older adults is a major challenge, and information on the combined effects of training and diet is particularly important. Here we aimed to evaluate the effects of 24 wk of resistance training combined with a healthy dietary approach (n-6/n-3 ratio healthy and physically active older women (65-70 years). The three-armed randomized controlled trial included a resistance training + healthy diet group (RT-HD), a resistance training group (RT), and controls (CON). All subjects included in the study were physically active and had low levels of serum inflammatory markers. In accordance with the dietary goals, the n-6/n-3 ratio dietary intake significantly decreased only in RT-HD by 42%. An increase in 1 repetition maximum in leg extension occurred in RT (+20.4%) and RT-HD (+20.8%), but not in CON. Interestingly, leg lean mass significantly increased only in RT-HD (+1.8%). While there were no changes in serum C-reactive protein and IL-6 levels, a significant decrease in serum level of the pro-inflammatory precursor arachidonic acid (-5.3 ± 9.4%) together with an increase in serum n-3 docosahexaenoic acid (+8.3%) occurred only in RT-HD. Altogether, this study demonstrates that the effects of resistance training on muscle mass in healthy older adults can be optimized by the adoption of a healthy diet.

    Long-term effects of high dietary protein intake on muscle and bone structure in the elderly are not clear. The aim of this study was to investigate the relationship between baseline protein intake and lean mass and BMC 5 yr later in a cohort of elderly postmenopausal women. A total of 862 community-dwelling women 75 +/- 3 yr of age provided baseline data including nutrient intake assessed by a food frequency questionnaire. At 5 yr, upper arm muscle area (UAMA) and body composition using DXA were measured. Baseline protein intake was 81 +/- 28 g/d (1.2 +/- 0.4 g/kg/d), contributing 19 +/- 3% of total energy intake. There were positive correlations between baseline protein intake and whole body and appendicular bone-free lean mass and BMC (r = 0.14-0.18, p 87 g/d) had 5.4-6.0% higher whole body and appendicular lean mass and UAMA and 5.3-6.0% higher whole body and appendicular BMC. These effects remained after adjusting for potential confounders. However, the effect on BMC disappeared after further adjustment for lean mass. This study shows that high protein intake is associated with long-term beneficial effects on muscle mass and size and bone mass in elderly women. The protein effect on bone may be partly mediated by its effects on muscle.

    Full Text Available Fat-free mass (FFM adaptations to physical training may differ between sexes based on disparities in fitness level, dietary intake, and levels of plasma amino acids (AA. This investigation aimed to determine FFM and plasma AA responses to military training, examine whether adaptations differ between male and female recruits, and explore potential associations between FFM and AA responses to training. Body composition and plasma AA levels were assessed in US Army recruits (n = 209, 118 males, 91 females before (baseline and every three weeks during basic combat training (BCT, a 10-week military training course. Body weight decreased in men but remained stable in women during BCT (sex-by-time interaction, P < 0.05. Fifty-eight percent of recruits gained FFM during BCT, with more (P < 0.05 females (88% gaining FFM than males (36%. Total plasma AA increased (P < 0.05 during BCT, with greater (P < 0.05 increases observed in females (17% then in males (4%. Essential amino acids (EAA and branched-chain amino acids (BCAA were increased (P < 0.05 in females but did not change in males (sex-by-time interaction, P < 0.05. Independent of sex, changes in EAA (r = 0.34 and BCAA (r = 0.27 from baseline were associated with changes in FFM (P < 0.05; greater (P < 0.05 increases in AA concentrations were observed for those who gained FFM. Increases in FFM and plasma AA suggest that BCT elicits a more pronounced anabolic response in women compared to men, which may reflect sex-specific differences in the relative intensity of the combined training and physiological stimulus associated with BCT.

    Previous studies on gene-lifestyle interaction and obesity have focused mostly on the FTO gene and physical activity, whereas little attention has been paid to sedentary behavior as indicated by television (TV) watching. We analyzed interactions between TV watching, leisure time physical activity, and genetic predisposition in relation to body mass index (BMI) in 7740 women and 4564 men from 2 prospective cohorts: The Nurses' Health Study and the Health Professionals Follow-up Study. Data on physical activity and TV watching were collected 2 years before assessment of BMI. A weighted genetic risk score was calculated on the basis of 32 established BMI-associated variants. In both women and men, the genetic associations with BMI strengthened with increased hours of TV watching. An increment of 10 points in the weighted genetic risk score was associated with 0.8 (SE, 0.4), 0.8 (SE, 0.2), 1.4 (SE, 0.2), 1.5 (SE, 0.2), and 3.4 (SE, 1.0) kg/m(2) higher BMI across the 5 categories of TV watching (0-1, 2-5, 6-20, 21-40, and >40 h/wk; P for interaction=0.001). In contrast, the genetic association with BMI weakened with increased levels of physical activity. An increment of 10 points in the weighted genetic risk score was associated with 1.5 (SE, 0.2), 1.3 (SE, 0.2), 1.2 (SE, 0.2), 1.2 (SE, 0.2), and 0.8 (SE, 0.2) kg/m(2) higher BMI across the quintiles of physical activity. The interactions of TV watching and physical activity with genetic predisposition in relation to BMI were independent of each other. A sedentary lifestyle, indicated by prolonged TV watching, may accentuate the predisposition to elevated adiposity, whereas greater leisure time physical activity may attenuate the genetic association.

    We studied the differences in the mean pre-pregnancy body mass index (BMI) and mean inter-pregnancy weight change in women of Russian, Somali and Kurdish origin and women in the general Finnish population. The population-based samples were from the Migrant Health and Wellbeing Study and the Health 2011 Survey conducted in six cities in Finland in 2010-2012. This study included women with at least one birth in Finland. Data on their previous pregnancies in Finland were obtained from the National Medical Birth Register for 318 Russian, 584 Somali and 373 Kurdish origin women and for 243 women in the general Finnish population (reference group). Data on pre-pregnancy weight and height were self-reported in early pregnancy. Linear logistic regression was the main method of analysis. The unadjusted mean pre-pregnancy BMI was higher in Somali (27.0 kg/m 2 , p<0.001) and Kurdish (25.8 kg/m 2 , p<0.001) women, but lower in Russian (22.2 kg/m 2 , p<0.001) women than in the reference group (24.1 kg/m 2 ). The adjusted coefficients for the difference in the mean pre-pregnancy BMI were -1.93 (95% CI -2.77 to -1.09) for Russian, 1.82 (95% CI 0.89-2.75) for Somali and 1.30 (95% CI 0.43-2.17) for Kurdish women compared with the reference group. Among women with at least two births, no statistically significant difference was observed in the mean inter-pregnancy weight change between the migrant groups and the reference group. Somali and Kurdish women had higher mean pre-pregnancy BMIs than women in the general Finnish population and may need special support and health promotion strategies for weight management.

    2017-10-01

    The proliferation of new psychoactive substances (NPS) in recent years has resulted in the development of numerous analytical methods for the detection and identification of known and unknown NPS derivatives. High-resolution mass spectrometry (HRMS) has been identified as the method of choice for broad screening of NPS in a wide range of analytical contexts because of its ability to measure accurate masses using data-independent acquisition (DIA) techniques. Additionally, it has shown promise for non-targeted screening strategies that have been developed in order to detect and identify novel analogues without the need for certified reference materials (CRMs) or comprehensive mass spectral libraries. This paper reviews the applications of HRMS for the analysis of NPS in forensic drug chemistry and analytical toxicology. It provides an overview of the sample preparation procedures in addition to data acquisition, instrumental analysis, and data processing techniques. Furthermore, it gives an overview of the current state of non-targeted screening strategies with discussion on future directions and perspectives of this technique.

    In menopause, changes in body fat distribution lead to increasing risk of cardiovascular disease and metabolic disorders. The aim of this study was to assess the association of adiposity using the conicity index (CI), body mass index (BMI) and waist circumference (WC) with cardiovascular risk factors (hypertension, diabetes and dyslipidaemia). The sample of this cross-sectional study was collected from June to October 2010 and 165 consecutive menopausal women who had attended the Health and Treatment Centre and Endocrine Research Centre of Firoozgar Hospital in Tehran, Iran were assessed. Age, weight, height, WC, waist-hip ratio (WHR), CI and fat mass were measured. Systolic and diastolic blood pressure (SBP and DBP), fasting blood glucose, insulin, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC) levels were also determined. All statistical analyses were performed by SPSS version 17 (SPSS Inc, Chicago, IL, USA). Results showed that BMI was positively and significantly associated with SBP (r = 0.21; p = 0.009). WC was positively and significantly correlated with SBP (r = 0.26; p = 0.02) and DBP (r = 0.16; p = 0.05). WHR was also significantly and positively associated with SBP (r = 0.29; p = 0.001). Age and WC were associated with CI quartiles at the 0.05 significance level. The correlation of CI quartiles with SBP and weight were at the 0.01 significance level. We showed a significant association of WC with SBP and DBP, and that BMI could be an important determining factor of SBP. For assessing the association between CI and cardiovascular risk factors, future studies with larger sample sizes are recommended.

    This study developed and examined the reach and impact of a culturally appropriate mass media campaign pilot, designed to increase awareness about the importance of mammography screening and the available community mammography services for low-income African American women ages 40 and above. We conducted formative research using focus groups to inform campaign development, resulting in five emergent themes-good breast health, holistic views of healthiness, cancer fatalism, fear of mammogram machines, and mammogram affordability. The campaign targeted specific low-income African American communities in the District of Columbia via print ads in Metro stations and on buses, print ads in the Washington Informer, and online ads on a local TV network website. Data were collected before, during, and after campaign implementation to assess reach and impact. Reach was measured by number of impressions (number of people exposed to the campaign), while impact was assessed via online ad click-through rates, website use and referrals, and mammography center calls. The campaign was successful in reaching the target audience, with a total combined reach from all media of 9,479,386 impressions. In addition, the mammography center received significant increases in new website visitors (1482 during the campaign, compared to 24 during the preceding period) as well as 97 calls to the dedicated phone line. Further research involving a more long-term investment in terms of funding and campaign run time, coupled with a more robust evaluation, is needed to assess if culturally appropriate mass media campaigns can generate increased mammography screening rates and decrease breast-cancer-related mortality.

    To evaluate the effect of pre-pregnancy body mass index on maternal and perinatal outcomes among adolescent pregnant women. We conducted this prospective cross-sectional study on 365 singleton adolescent pregnancies (aged between 16 and 20 years) at a Maternity Hospital, between December 2014 and March 2015. We divided participants into two groups based on pre-pregnancy body mass index (BMI): overweight and obese adolescent (BMI at or above 25.0 kg/m) and normal weight (BMI between 18.5 and 24.99 kg/m) adolescent. We used multivariate analysis to evaluate the association of the risk of adverse pregnancy outcomes and pre-pregnancy BMI. The prevalence of maternal overweight/obesity and normal weight was 34.6% (n = 80) and 65.4% (n = 261) in the study population, respectively. Compared with normal-weight teens (n = 234), overweight/obese teens (n = 71) were at higher risk for cesarean delivery (odds ratio [OR] 0.7, 95% confidence interval [CI] 0.4-1.4), preeclampsia (adjusted odds ratio [OR] 0.1, 95% confidence interval [CI] 0.02-0.9) and small of gestational age (odds ratio [OR] 0.2, 95% confidence interval [CI] 0.1-0.9). BMI increased during pre-pregnancy could be an important preventable risk factor for poor obstetric complications in adolescent pregnancies, and for these patients prevention strategies (e.g., nutritional counseling, weight-loss, regular physical activity) for obesity are recommended before getting pregnant.

    The nuclear weapons production has resulted in accumulation of a large quantity of plutonium and uranium highly enriched with uranium-235 isotope (many tons). The work under ISTC Project 332B-97 treated the issues of safe plutonium storage through making critical-mass-free plutonium oxide compositions with neutron poisons. This completely excludes immediate utilization (without chemical reprocessing) of retained plutonium in nuclear devices. It is therewith possible to locate plutonium most compactly in the storage facility, which would allow reduction in required storage areas and costs. The issues of the surplus weapon-grade plutonium management and utilization have been comprehensively studied in the recent decade. The issues are treated in multiple scientific publications, conferences, and seminars. At the same time, issues of nuclear power engineering actinide waste storage are studied no less extensively. The general issues are material radioactivity and energy release and nuclear accident hazards due to critical mass generation. Plutonium accumulated in nuclear power plant spent fuel is more accessible than weapon-grade plutonium and can become of higher and higher interest with time as its activity reduces, including as material for nuclear devices. The urgency of plutonium management is presently related not only to accumulation of surplus weapon-grade plutonium, but also to the fact that it is high time to decide what has to be done regarding reactor plutonium. Presently, the possibility of actinide separation from NPP spent nuclear fuel and compact underground burial separately from other (mainly fragment) activity is being considered. Actinide and neutron poison base critical-mass-free ceramic materials (similar to plutonium ceramics) may be useful for this burial method. (author)

    Sarcopenia is associated with loss of muscle mass as well as an increased risk of physical disability in elderly people. This study was aimed to investigate the effect of elastic band resistance training (ERT) on muscle mass and physical function in older women with sarcopenic obesity. A randomized controlled trial with an intention-to-treat analysis was conducted. A total of 56 women (mean ± SD age 67.3 ± 5.1 years) were randomly assigned to the experimental group receiving 12 weeks of ERT and to the control group receiving no exercise intervention. Lean mass (measured using a dual-energy X-ray absorptiometer), physical capacity (assessed using the global physical capacity score), and a 36-item short form questionnaire were conducted at the baseline examination (T 0 ), as well as the 3-month (T 1 ) and 9-month followups (T 2 ). At T 1 and T 2 , the between-group difference was measured in total skeletal mass relative to T 0 , with mean differences of 0.70 kg (95% CI 0.12-1.28; P physical capacity, and physical function outcomes. The ERT exerted a significant beneficial effect on muscle mass, muscle quality, and physical function in older women with sarcopenic obesity.

    Globally, rural to urban migration is accompanied by changes in dietary patterns and lifestyle that have serious health implications, including development of low bone mass. We hypothesized that serum 25 (OH) vitamin D3 (25[OH]D3) levels will be lower, bone turnover higher, and nutrition inadequate in urban postmenopausal black women, increasing risk for low bone mass. We aimed to assess the prevalence of risk factors for low bone mass in 1261 black women from rural and urban areas in the North West Province of South Africa (Prospective Urban and Rural Epidemiology-South Africa project). Fasting blood samples were taken; and participants were interviewed to complete questionnaires on self-reported diseases, fractures, and dietary intakes. Bone health markers were assessed in a subgroup of 658 women older than 45 years. Specific lifestyle risk factors identified were inactivity, smoking, injectable progestin contraception use, and high alcohol consumption. Dietary risk factors identified were low calcium and high animal protein, phosphorous, and sodium intakes. The 25(OH)D3 and C-terminal telopeptide (CTX) levels were significantly higher in the rural vs the urban women older than 50 years. Parathyroid hormone (PTH) levels increased with age in both groups. The 25(OH)D levels were inversely correlated with CTX and PTH in rural women. In urban women, PTH and CTX were correlated while dietary calcium was inversely correlated with CTX and PTH with 25(OH)D3. The combination of low dietary calcium (<230 mg/d), marginally insufficient 25(OH)D3 status, and raised PTH may result in increased bone resorption. Further research is required to assess bone health and fracture risk in black African women. Copyright © 2011 Elsevier Inc. All rights reserved.

  12. Prader-Willi Critical Region, a Non-Translated, Imprinted Central Regulator of Bone Mass: Possible Role in Skeletal Abnormalities in Prader-Willi Syndrome.

    Directory of Open Access Journals (Sweden)

    Ee-Cheng Khor

    Full Text Available Prader-Willi Syndrome (PWS, a maternally imprinted disorder and leading cause of obesity, is characterised by insatiable appetite, poor muscle development, cognitive impairment, endocrine disturbance, short stature and osteoporosis. A number of causative loci have been located within the imprinted Prader-Willi Critical Region (PWCR, including a set of small non-translated nucleolar RNA's (snoRNA. Recently, micro-deletions in humans identified the snoRNA Snord116 as a critical contributor to the development of PWS exhibiting many of the classical symptoms of PWS. Here we show that loss of the PWCR which includes Snord116 in mice leads to a reduced bone mass phenotype, similar to that observed in humans. Consistent with reduced stature in PWS, PWCR KO mice showed delayed skeletal development, with shorter femurs and vertebrae, reduced bone size and mass in both sexes. The reduction in bone mass in PWCR KO mice was associated with deficiencies in cortical bone volume and cortical mineral apposition rate, with no change in cancellous bone. Importantly, while the length difference was corrected in aged mice, consistent with continued growth in rodents, reduced cortical bone formation was still evident, indicating continued osteoblastic suppression by loss of PWCR expression in skeletally mature mice. Interestingly, deletion of this region included deletion of the exclusively brain expressed Snord116 cluster and resulted in an upregulation in expression of both NPY and POMC mRNA in the arcuate nucleus. Importantly, the selective deletion of the PWCR only in NPY expressing neurons replicated the bone phenotype of PWCR KO mice. Taken together, PWCR deletion in mice, and specifically in NPY neurons, recapitulates the short stature and low BMD and aspects of the hormonal imbalance of PWS individuals. Moreover, it demonstrates for the first time, that a region encoding non-translated RNAs, expressed solely within the brain, can regulate bone mass in health

    For semilinear elliptic equations -Δ u = λ| u| p-2 u-| u| q-2 u, boundary value problems in bounded and unbounded domains are considered. In the plane of exponents p × q, the so-called curves of critical exponents are defined that divide this plane into domains with qualitatively different properties of the boundary value problems and the corresponding parabolic equations. New solvability conditions for boundary value problems, conditions for the stability and instability of stationary solutions, and conditions for the existence of global solutions to parabolic equations are found.

    Full Text Available The article deals with the impact of diabetes mellitus (DM on the phosphorus and calcium metabolism in postmenopausal women, depending on the type and duration of the disease, duration of menopause, body mass and type of hypoglycemic therapy. The state of phosphorus and calcium metabolism in 86 women with type 1 DM (13 patients and type 2 DM (73 patients was studied. In all patients, the concentration of calcium and phosphorus in the blood was within normal limits. It was found that the concentration of ionized calcium, total calcium and inorganic phosphorus in the blood can not be the main criterion for the state of bone mineral density in postmenopausal women with DM. Sulfonylureas and insulin in combination with biguanides have no effect on the status of phosphorus and calcium metabolism in postmenopausal women with type 2 DM.

    Despite the proven benefits of Pap testing, Korean American women have one of the lowest cervical cancer screening rates in the United States. This study examined how cultural factors are associated with Pap test utilization among Korean American women participants. Quota sampling was used to recruit 202 Korean American women participants residing in New York City. Hierarchical logistic regression was used to assess the association of cultural variables with Pap test receipt. Overall, participants in our study reported significantly lower Pap test utilization; only 58% reported lifetime receipt of this screening test. Logistic regression analysis revealed one of the cultural variables--prevention orientation--was the strongest correlate of recent Pap test use. Older age and married status were also found to be significant predictors of Pap test use. Findings suggest cultural factors should be considered in interventions promoting cervical cancer screening among Korean American women. Furthermore, younger Korean American women and those not living with a spouse/partner should be targeted in cervical cancer screening efforts.

    An aggregate index is potentially useful to represent neighbourhood obesogenicity. We created a conceptually-based obesogenicity index and examined its association with body mass index (BMI) among 3786 women (age 18-45y) in socio-economically disadvantaged neighbourhoods in Victoria, Australia. The index included 3 items from each of 3 domains: food resources (supermarkets, green grocers, fast food restaurants), recreational activity resources (gyms, pools, park space), and walkability (4+ leg intersections, neighbourhood walking environment, neighbourhood safety), with a possible range from 0 to 18 reflecting 0-2 for each of the 9 items. Using generalised estimating equations, neighbourhood obesogenicity was not associated with BMI in the overall sample. However, stratified analyses revealed generally positive associations with BMI in urban areas and inverse associations in rural areas (interaction p=0.02). These analyses are a first step towards combining neighbourhood characteristics into an aggregate obesogenicity index that is transparent enough to be adopted elsewhere and to allow examination of the relevance of its specific components in different settings.

    A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Present-day inductively coupled plasma-mass spectrometry (ICP-MS) instrumentation is described briefly. Emphasis is placed on performance characteristics for geoanalysis, geochemistry, and hydrology. Applications where ICP-MS would be indispensable are indicated. Determination of geochemically diagnostic trace elements (such as the rare earth elements [REE], U and Th), of isotope ratios for fingerprinting, tracer and other geo-isotope applications, and benchmark isotope dilution determinations are considered to be typical priority applications for ICP-MS. It is concluded that ICP-MS furnishes unique geoanalytical and environmental data that are not readily provided by conventional spectroscopic (emission and absorption) techniques.

    Full Text Available Over the last years, the pretreatment of biomass as a source of energy has become one of the most important steps of biomass conversion. In this work the effect of a mild subcritical hydrothermal carbonization of a tropical woody biomass was studied. Results indicate considerable change in carbon content from 52.78% to 65.1%, reduction of oxygen content from 41.14% to 28.72% and ash slagging and fouling potential. Even though decarboxylation, decarbonylation and dehydration reactions take place, dehydration is the one that prevails. The mass and energy balance was affected by the treatment conditions than the severity of the treatment.

    To investigate the effects of excessive pre-pregnancy body mass index (BMI) and abnormal gestational weight gain on adverse outcomes in women with chronic hypertension (CH). A retrospective cohort study of CH women with singleton pregnancy delivered at our Institution in 2002-2013. Women were categorized as normal, overweight, and obese, according to their pre-pregnancy BMI. Further stratification was based on gestational weight gain (insufficient, adequate, and excessive) as defined by 2009 IOM guidelines. Gestational diabetes, hypothyroidism, superimposed preeclampsia, preterm birth gain increased odds of small for gestational age neonate in normal BMI women (aOR, 1.82; 95% CI 1.31-2.07), whereas excessive gain was associated with superimposed preeclampsia in normal BMI patients (aOR, 3.51; 95% CI, 1.16-7.89) and with cesarean delivery in obese women (aOR, 2.96; 95% CI, 1.09-5.81). Excessive pre-conception BMI and abnormal gestational weight gain increase odds of pregnancy complications in CH women. Our results stress the importance of pre-conception counseling for weight normalization in CH women, and support IOM recommendations for adequate weight gain during CH pregnancies.

    Body mass index (BMI) lower than 16 is the most severe category of adult undernutrition and is associated with substantial morbidity, increased mortality, and poor maternal-fetal outcomes such as low-birth-weight newborns. Little is known about the prevalence and distribution of BMI lower than 16 in low- and middle-income countries (LMIC). To determine the prevalence and distribution of BMI lower than 16 and its change in prevalence over time in women in LMIC. Cross-sectional data analysis composed of nationally representative surveys from 1993 through 2012 from the Demographic and Health Surveys Program. Women aged 20 through 49 years from 60 LMIC (N = 500,761) and a subset of 40 countries with repeated surveys (N = 604,144) were examined. Wealth was measured using a validated asset index, age was categorized in deciles, education by highest completed level (none, primary, secondary, or greater), and place of residence as urban vs rural. The primary outcome was BMI lower than 16. Analyses assessed the prevalence of BMI lower than 16, its association with sociodemographic factors, and change in prevalence. Logistic regression models were used to calculate odds ratios (ORs), adjusting for survey design and age structure. Among countries examined, the pooled, weighted, and age-standardized prevalence of BMI lower than 16 was 1.8% (95% CI, 1.7% to 1.8%) with the highest prevalence in India (6.2% [95% CI, 5.9% to 6.5%]), followed by Bangladesh (3.9% [95% CI, 3.4% to 4.3%]), Madagascar (3.4% [95% CI, 2.8% to 4.0%], Timor-Leste (2.9% [95% CI, 2.4% to 3.2%]), Senegal (2.5% [95% CI, 1.9% to 3.2%]), and Sierra Leone (2.2% [95% CI, 1.3% to 3.0%]); and 6 countries had prevalences lower than 0.1% (Albania, Bolivia, Egypt, Peru, Swaziland, and Turkey). The prevalence of BMI lower than 16 in women with a secondary or higher education level was 0.51% (95% CI, 0.47% to 0.55%), and in mutually adjusted models, a less than primary education level was associated with an OR of

    Although muscle mass influences strength in older adults, it is unclear whether low lean mass measured by dual-energy X-ray absorptiometry (DXA) is an independent risk factor for hip fracture. Our objective was to determine the association between DXA lean mass and incident hip fracture risk among 1978 women aged 50 years and older participating in the Framingham Study Original and Offspring cohorts. Leg and total body lean mass (kg) were assessed from whole-body DXA scans collected in 1992-2001. Hip fracture follow-up extended from DXA assessment to the occurrence of fracture, death, drop-out, or end of follow-up in 2007. Cox proportional hazards regression was used to calculate hazard ratios (HR) and 95% confidence intervals (CI) estimating the relative risk of hip fracture associated with a 1-kg increase in baseline lean mass. Mean age was 66 years (range 50-93). Over a median of 8 years of follow-up, 99 hip fractures occurred. In models adjusted for age, height, study cohort, and percent total body fat, neither leg (HR 1.11; 95% CI 0.94, 1.31) nor total body (HR 1.06; 95% CI 0.99, 1.13) lean mass were associated with hip fracture. After further adjustment for femoral neck bone mineral density, leg lean mass results were similar (HR 1.10; 95% CI 0.93, 1.30). In contrast, 1 kg greater total body lean mass was associated with 9% higher hip fracture risk (HR 1.09; 95% CI 1.02, 1.18). Our findings suggest that in women, lower lean mass measured by DXA is not associated with increased risk of hip fracture.

    To compare the clinical classification of the body mass index (BMI) and percentage body fat (PBF) for the prediction of inflammatory and atherogenic lipid profile risk in older women. Cross-sectional analytical study with 277 elderly women from a local community in the Federal District, Brazil. PBF and fat-free mass (FFM) were determined by dual energy X-ray absorptiometry. The investigated inflammatory parameters were interleukin 6 and C-reactive protein. Twenty-five percent of the elderly women were classified as normal weight, 50% overweight, and 25% obese by the BMI. The obese group had higher levels of triglycerides and very low-density lipoproteins than did the normal weight group (P≤0.05) and lower levels of high-density lipoproteins (HDL) than did the overweight group (P≤0.05). According to the PBF, 49% of the elderly women were classified as eutrophic, 28% overweight, and 23% obese. In the binomial logistic regression analyses including age, FFM, and lipid profile, only FFM (odds ratio [OR]=0.809, 95% confidence interval [CI]: 0.739-0.886; Pprofile is key to assessing the risk of cardiometabolic diseases. Classification based on dual energy X-ray absorptiometry measures, along with biochemical and inflammatory parameters, seems to have a great clinical importance, since it allows the lipid profile eutrophic distinction in elderly overweight women.

    We previously reported the secretion of apolipoprotein apoC-I, apoC-II, apoC-III, and apoE from adipose tissue in postmenopausal obese women, suggesting their potential regulation by energy balance in humans. We examined the changes of these apolipoproteins, in relation to changes in cardiometabolic risks, following a hypocaloric diet in overweight/obese women. A total of 137 postmenopausal overweight/obese women who were free of chronic disease were examined at baseline, 56 women of whom were reevaluated following a 6-month hypocaloric diet. At baseline, there was no association between the plasma transferable apolipoproteins with any index of adiposity, insulin sensitivity, lipids, or inflammation, except for apoE with peripheral fat mass (r = 0.18, P hypocaloric diet reduced adiposity, insulin resistance, and inflammatory markers but had no significant effects on plasma transferable apolipoproteins or lipids, whose average concentrations were within normal range at baseline. The changes in total and central, but not peripheral, fat mass associated with changes of apoC-I only (r = 0.28 and r = 0.43; respectively, P < .05). Post-weight-loss apoC-I increased in some women (52%) yet it decreased in others, however there were no differences in cardiometabolic risk factors between the 2 groups. Plasma apoC-I, apoC-II, apoC-III, and apoE are not associated with adiposity, insulin sensitivity, or inflammation in obese but healthy postmenopausal women.

    Full Text Available The aim of this study was to investigate whether protein supplementation helps prevent the loss of fat-free mass during weight loss. The sample was composed of seventy-eight obese adult Japanese women, assigned into four different programs: diet-alone (D, n=24, diet-alone with protein supplementation (DP, n=16, diet-plusexercise (DE, n=17, and diet-plus-exercise with protein supplementation (DEP, n=21. All participants restricted their energy intakes to 1200 kcal/day, and participants in DE and DEP had the exercise session including aerobic exercise of approximately 90 min/day, 3 day/week. Participants enrolled in protein supplementation groups received an additional 14 g/day of protein. Measures on body composition were conducted before and after the program by DXA. All programs yielded significant weight (6.9 to 9.5 kg and fat (4.1 to 7.6% reduction. Total fat-free mass significantly decreased in D, DP and DE groups, whereas for DEP group the decrease was not significant. Regionalfat-free mass lowered for D and DP groups in leg, arms and trunk. For those in DE group, fat-free mass in trunk was not significantly decreased, and for those in DEP group, fat-free mass in leg and trunk did not differ significantly after the program. However, no significant differences of changes in fat-free mass were observed in comparisons among all groups. Our results confirmed the efficiency of weight loss intervention on fat-mass reduction through diet and exercise. However, fat-free mass does not appear to be preserved by protein supplementation, suggesting that its influence on a short-term weight reduction program is not apparent.

    Full Text Available Short stature, a marker for undernutrition early in life, has been associated with obesity in Brazilian women, but not in men. We tested the hypothesis that weight gain during the reproductive years could explain this gender difference. A national two-stage household survey of mothers with one or more children under five years of age was conducted in Brazil in 1996. The subjects were women aged 20 to 45 years (N = 2297, with last delivery seven months or more prior to the interview. The regions of the country were divided into rural, North/Northeast (urban underdeveloped and South/Southeast/Midwest (urban developed. The dependent variables were current body mass index (BMI measured, BMI prior to childbearing (reported, and BMI change. Socioeconomic variables included mother's years of education and family purchasing power score. A secondary analysis was restricted to primiparous women. The prevalence of current overweight and overweight prior to childbearing (BMI > or = 25 kg/m² was higher among shorter women (<1.50 m compared to normal stature women only in the urban developed region (P < 0.05. After adjustment for socioeconomic variables, age, parity, BMI prior to childbearing, and age at first birth, current BMI was 2.39 units higher (P = 0.008 for short stature women living in the urban developed area compared with short stature women living in the urban underdeveloped area. For both multiparous and primiparous women, BMI gain compared to the value prior to childbearing was significantly higher among short stature women living in the urban developed region (P <= 0.04. These results provide clear evidence that short stature was associated with a higher BMI and with an increased risk of weight gain/retention with pregnancy in the developed areas of Brazil, but not in the underdeveloped ones.

    The aim of this study was to evaluate whether overweight and obesity are associated with arterial abnormalities in postmenopausal women and the contribution of the metabolic syndrome. A total of 390 postmenopausal women (mean age, 63.1 ± 7.7 y) living in the metropolitan area of Naples, Southern Italy, and participating in a population-based cohort study (Progetto Atena) were offered an ultrasound examination of the carotid arteries; 370 women accepted. Blood pressure, serum high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, fasting glucose, insulin, apolipoprotein B, and high-sensitivity C-reactive protein were measured in all participants. Women in the second and third tertiles of body mass index showed a greater common carotid intima-media thickness compared with those in the first tertile (tertile II vs I, odds ratio, 2.15; P = 0.013; tertile III vs I, odds ratio, 2.24; P = 0.018), adjusted for age and metabolic syndrome. Obese and overweight postmenopausal women showed greater common carotid lumen diameters as compared with lean postmenopausal women (mean ± SD, 6.36 ± 0.86, 6.16 ± 0.65, and 5.96 ± 0.59 mm, respectively; P women. The statistical significance between obese and lean postmenopausal women was retained even after adding the components of the metabolic syndrome as covariates. These findings indicate an association between overweight, obesity, and preclinical carotid artery abnormalities, independently of the metabolic syndrome, in a population of postmenopausal women.

    The critical heat flux (CHF) is the maximum heat flux just before a boiling crisis; its importance as a measurement of nuclear reactor power capability design as well as in the safety of reactors has been recognized. With emphasis on CHF behavior under subcooled and low-quality (i.e., 2 ·s), an improved model that uses the sublayer dry out theory has been developed. Based on experimental observations of CHF, the model assumes that CHF under such conditions is of the departure from nucleate boiling type. Based on the postulation that CHF is triggered by Helmholtz instability in the sublayer steam-liquid system, the model was developed by a simple energy balance of liquid sublayer evaporation as the vapor blanket tends to disturb the balance between the buoyancy force and the drag force exerted upon it. The model is compared with the well-known Biasi et al. correlation as well as the Atomic Energy of Canada Limited lookup table against 102 uniformly heated round tube CHF data and 34 nonuniformly heated round tube CHF data. The comparison shows that the model provides better accuracy and a reasonable agreement between the predicted values and experimental CHF data

    A method of determination neutrons multiplication in deep sub-critical multiplying media has been developed. It is based on a modified of Rossi - alpha method. It will consist in use of integral on time (a method of the areas) from correlated parts of distribution and integral in area, independent of time a part of distribution (area of a constant background). It allows to spend the calculated analysis, using the integrated equation on time for a neutrons flux and to not use representation of point kinetic model. A calculation spatially-correlation factor the adjoint (relative the detector count rate) inhomogeneous equation is used. Its calculation takes into account fission both in multiplying media and in a spontaneous neutron source. Measurements with plutonium-steel and uranium-steel blocks, and blocks from uranium and plutonium dioxide of different enrichment are have been carried out. The measured values of neutrons multiplication in a range 1.03-1.82 will be well coordinated to results of calculations. The question on an opportunity of definition of weight of the measured blocks of fissile material is considered [ru

    2005-01-01

    The analytical performance of cold vapor atomic absorption spectrometry (CV AAS), graphite furnace atomic absorption spectrometry (GF AAS) and inductively coupled plasma mass spectrometry (ICP-MS) for mercury determination have been investigated with the use of two reference materials SRM 2710 Montana I Soil and BCR-144R (sewage sludge from domestic origin). The digestion conditions and their influence on determination of mercury have been studied. Samples were decomposed by microwave digestion in closed vessels with the use of HCl alone or mixture of HCl+HNO 3 +HF. The digestion solutions were analyzed by CV AAS using NaBH 4 as a reducing agent, by GF AAS with Pd or mixture of Pd/Rh as modifiers and by ICP-MS with Rh as internal standard. In the case of CV AAS, results were not dependent on digestion conditions. In the case of GF AAS and ICP-MS, results depended significantly on digestion conditions; in both cases, the use of the mixture of acids as defined above suppressed the signal of mercury. Therefore, in those cases, the microwave digestion with HCl is recommended. Detection limits of 0.003, 0.01 and 0.2 μg g -1 were achieved by ICP-MS, CV AAS and GF AAS, respectively

    Ambient desorption/ionization mass spectrometry (MS) has gained growing interest during the last decade due to its high analytical performance and yet simplicity. Here, one of the recently developed ambient desorption/ionization MS sources, the flowing atmospheric-pressure afterglow (FAPA) source, was investigated in detail regarding background ions and typical ionization patterns in the positive as well as the negative ion mode for a variety of compound classes, comprising alkanes, alcohols, aldehydes, ketones, carboxylic acids, organic peroxides and alkaloids. A broad range of signals for adducts and losses was found, besides the usually emphasized detection of quasimolecular ions, i.e. [M + H](+) and [M - H](-) in the positive and the negative mode, respectively. It was found that FAPA-MS is best suited for polar analytes containing nitrogen and/or oxygen functionalities, e.g. carboxylic acids, with low molecular weights and relatively high vapor pressures. In addition, the source was used in proof-of-principle studies, illustrating the capabilities and limitations of the technique: Firstly, traces of cocaine were detected and unambiguously identified on euro banknotes using FAPA ionization in combination with tandem MS, suggesting a correlation between cocaine abundance and age of the banknote. Secondly, FAPA-MS was used for the identification of acidic marker compounds in organic aerosol samples, indicating yet-undiscovered matrix and sample surface effects of ionization pathways in the afterglow region.

    Human arsenic methylation efficiency has been consistently associated with arsenic-induced disease risk. Interindividual variation in arsenic methylation profiles is commonly observed in exposed populations, and great effort has been put into the study of potential determinants of this variability. Among the factors that have been evaluated, body mass index (BMI) has not been consistently associated with arsenic methylation efficiency; however, an underrepresentation of the upper BMI distribution was commonly observed in these studies. This study investigated potential factors contributing to variations in the metabolism of arsenic, with specific interest in the effect of BMI where more than half of the population was overweight or obese. We studied 624 adult women exposed to arsenic in drinking water from three independent populations. Multivariate regression models showed that higher BMI, arsenic (+ 3 oxidation state) methyltransferase (AS3MT) genetic variant 7388, and higher total urinary arsenic were significantly associated with low percentage of urinary arsenic excreted as monomethylarsonic acid (%uMMA) or high ratio between urinary dimethylarsinic acid and uMMA (uDMA/uMMA), while AS3MT genetic variant M287T was associated with high %uMMA and low uDMA/uMMA. The association between BMI and arsenic methylation efficiency was also evident in each of the three populations when studied separately. This strong association observed between high BMI and low %uMMA and high uDMA/uMMA underscores the importance of BMI as a potential arsenic-associated disease risk factor, and should be carefully considered in future studies associating human arsenic metabolism and toxicity.

    This study was conducted to determine the following: (1) whether matrix metalloproteinase-1 (MMP-1) is increased in systemic vessels of preeclamptic women, (2) whether this increase might be mediated by neutrophils, and (3) whether MMP-1 could be responsible for vascular dysfunction. Omental arteries and plasma were collected from healthy pregnant and preeclamptic women. Omental arteries were evaluated for gene and protein expression of MMP-1, collagen type 1α, tissue inhibitor of metalloproteinase-1, and vascular reactivity to MMP-1. Gene and protein expression levels were also evaluated in human vascular smooth muscle cells (VSMCs) co-cultured with activated neutrophils, reactive oxygen species, or tumor necrosis factor α. Vessel expression of MMP-1 and circulating MMP-1 levels were increased in preeclamptic women, whereas vascular expression of collagen or tissue inhibitor of metalloproteinase-1 were down-regulated or unchanged. In cultured VSMCs, the imbalance in collagen-regulating genes of preeclamptic vessels was reproduced by treatment with neutrophils, tumor necrosis factor α, or reactive oxygen species. Chemotaxis studies with cultured cells revealed that MMP-1 promoted recruitment of neutrophils via vascular smooth muscle release of interleukin-8. Furthermore, MMP-1 induced vasoconstriction via protease-activated receptor-1, whose expression was significantly increased in omental arteries of preeclamptic women and in VSMCs co-cultured with neutrophils. Collectively, these findings disclose a novel role for MMP-1 as a mediator of vasoconstriction and vascular dysfunction in preeclampsia. Copyright © 2011 American Society for Investigative Pathology.

    Elizabeth Dao

    Full Text Available OBJECTIVES: To investigate the independent contribution of change in sub-total body fat and lean mass to cognitive performance, specifically the executive processes of selective attention and conflict resolution, in community-dwelling older women. METHODS: This secondary analysis included 114 women aged 65 to 75 years old. Participants were randomly allocated to once-weekly resistance training, twice-weekly resistance training, or twice-weekly balance and tone training. The primary outcome measure was the executive processes of selective attention and conflict resolution as assessed by the Stroop Test. Sub-total body fat and lean mass were measured by dual-energy x-ray absorptiometry (DXA to determine the independent association of change in both sub-total body fat and sub-total body lean mass with Stroop Test performance at trial completion. RESULTS: A multiple linear regression model showed reductions in sub-total body fat mass to be independently associated with better performance on the Stroop Test at trial completion after accounting for baseline Stroop performance, age, baseline global cognitive state, baseline number of comorbidities, baseline depression, and experimental group. The total variance explained was 39.5%; change in sub-total body fat mass explained 3.9% of the variance. Change in sub-total body lean mass was not independently associated with Stroop Test performance (P>0.05. CONCLUSION: Our findings suggest that reductions in sub-total body fat mass - not sub-total lean mass - is associated with better performance of selective attention and conflict resolution.

    Four different, low flow parallel path Mira Mist CE nebulizers were evaluated and compared in support of an ongoing project related to the use of microseparation techniques interfaced to inductively coupled plasma mass spectrometry for the quantification of cobalamin species (Vitamin B12). For the characterization of the different Mira Mist CE nebulizers, the nebulizer orientation as well as the effect of methanol on analytical response was the focus of the study. The position of the gas outlet on the nebulizer which consistently provided the maximum signal was when it was rotated to the 11 o'clock position when the nebulizer is viewed end-on. With this orientation the increased signal may be explained by the fact that the cone angle of the aerosol is such that the largest percentage of the aerosol is directed to the center of the spray chamber and consequently into the plasma. To characterize the nebulizer's performance, the signal response of a multielement solution containing elements with a variety of ionization potentials was used. The selection of elements with varying ionization energies and degrees of ionization was essential for a better understanding of observed increases in signal enhancement when methanol was used. Two different phenomena contribute to signal enhancement when using methanol: the first is improved transport efficiency and the second is the 'carbon enhancement effect'. The net result was that as much as a 30-fold increase in signal was observed for As and Mg when using a make-up solution of 20% methanol at a 15 μL/min flow rate which is equivalent to a net volume of 3 μL/min of pure methanol

Methods Retrospective observational study in 394 severe or critical pregnant women admitted to a hospital with pH1N1 influenza from Sep. 1, 2009 to Dec. 31, 2009. rRT-PCR testing was used to confirm infection. In-hospital mortality was the primary endpoint of this study. Univariable logistic analysis and multivariate logistic regression analysis were used to investigate the potential factors on admission that might be associated with the maternal and neonatal mortality. Results 394 pregnant women were included, 286 were infected with pH1N1 in the third trimester. 351 had pneumonia, and 77 died. A PaO2/FiO2 ≤ 200 (odds ratio (OR, 27.16; 95% confidence interval (CI, 2.64-279.70 and higher BMI (i.e. ≥ 30 on admission (OR, 1.26; 95% CI, 1.09 to 1.47 were independent risk factors for maternal death. Of 211 deliveries, 146 neonates survived. Premature delivery (OR, 4.17; 95% CI, 1.19-14.56 was associated neonatal mortality. Among 186 patients who received mechanical ventilation, 83 patients were treated with non-invasive ventilation (NIV and 38 were successful with NIV. The death rate was lower among patients who initially received NIV than those who were initially intubated (24/83, 28.9% vs 43/87, 49.4%; p = 0.006. Septic shock was an independent risk factor for failure of NIV. Conclusions Severe hypoxemia and higher BMI on admission were associated with adverse outcomes for pregnant women. Preterm delivery was a risk factor for neonatal death among pregnant women with pH1N1 influenza infection. NIV may be useful in selected pregnant women without septic shock.

  4. Criticality safety

    International Nuclear Information System (INIS)

    Walker, G.

    1983-01-01

    When a sufficient quantity of fissile material is brought together a self-sustaining neutron chain reaction will be started in it and will continue until some change occurs in the fissile material to stop the chain reaction. The quantity of fissile material required is the 'Critical Mass'. This is not a fixed quantity even for a given type of fissile material but varies between quite wide limits depending on a number of factors. In a nuclear reactor the critical mass of fissile material is assembled under well-defined condition to produce a controllable chain reaction. The same materials have to be handled outside the reactor in all stages of fuel element manufacture, storage, transport and irradiated fuel reprocessing. At any stage it is possible (at least in principle) to assemble a critical mass and thus initiate an accidental and uncontrollable chain reaction. Avoiding this is what criticality safety is all about. A system is just critical when the rate of production of neutrons balances the rate of loss either by escape or by absorption. The factors affecting criticality are, therefore, those which effect neutron production and loss. The principal ones are:- type of nuclide and enrichment (or isotopic composition), moderation, reflection, concentration (density), shape and interaction. Each factor is considered in detail.

Agreement between bioelectrical impedance and dual-energy x-ray absorptiometry to track changes in fat-free mass after resistance training in older women. J Strength Cond Res XX(X): 000-000, 2018-The aim of our study was to compare the agreement between bioelectrical impedance (BIA) and dual-energy X-ray absorptiometry (DXA) to track changes on fat-free mass (FFM) after a resistance training (RT) program in older women. Forty-three older women (65.2 ± 4.6 years, 59.5 ± 9.2 kg, 156.4 ± 6.0 cm, 24.3 ± 3.3 kg·m) participated in a RT intervention (12 weeks, 8 exercises, 2 sets, 10-15 repetitions, 3 nonconsecutive days per week). Fat-free mass changes were determined by a single-frequency BIA device (EQ1), 6 BIA prediction equations for older women (EQ2, EQ3, EQ4, EQ5, EQ6, and EQ7), and DXA. At pretraining, 3 equations overpredicted, and 3 underpredicted DXA FFM (F = 244.63, p FFM (F = 176.25, p FFM (0.65 ± 0.82 kg; p FFM. Low correlations between FFM and equation change values suggest that single-frequency BIA-derived equations may not provide sufficient accuracy to track changes in FFM after 12 weeks of RT in older women.

    Full Text Available O artigo apresenta os principais resultados de uma pesquisa que investigou, sob a ótica crítica e de gênero e da abordagem qualitativa, os significados simbólicos e concretos do fumar feminino. Foram realizadas 14 entrevistas semi-estruturadas com mulheres tabagistas em diversas etapas do processo de cessação. O lócus da pesquisa foi um programa de tratamento do tabagismo em um hospital público do Rio de Janeiro, Brasil. Os resultados evidenciaram o quanto o cigarro esteve imbricado em suas trajetórias sociais e de gênero, desempenhando importante papel de apoio no enfrentamento das inúmeras dificuldades de sobrevivência. Emergiu, como categoria empírica central, o "cigarro companheiro", sempre disponível para aplacar a ansiedade e a solidão, além de também ser fonte de prazer e relaxamento. O enfoque crítico de gênero evidenciou o quanto a sobrecarga de trabalho, reprodutivo e produtivo, potencializa o fumar feminino. Na assistência à saúde, para se conquistar a adesão das mulheres tabagistas ao difícil percurso da cessação, deve-se levar em conta os complexos entrelaçamentos entre as dimensões sociais e de gênero no estabelecimento da associação do cigarro a um "companheiro".This article presents the main results of a study that examined the symbolic and material meanings of women's smoking, adopting a critical and qualitative gender approach. Semi-structured interviews were held with 14 women smokers in different stages of the smoking cessation process. The research locus was a tobacco treatment program located in a public hospital in Rio de Janeiro, Brazil. The findings showed how deeply smoking is interwoven in these women's social and gender trajectories, playing a decisive support role when they have to deal with various difficulties in life. The cigarette as a "companion" emerged as the main empirical category, as something always available to quell anxiety and loneliness, as well as a source of pleasure

    Full Text Available BackgroundMany epidemiologic studies have shown that women with type 2 diabetes have an increased risk of developing cardiovascular disease compared with men with diabetes. The aim of this study is to elucidate whether disparities of adiposity, age and insulin resistance (IR at the time of diabetes diagnosis exist between women and men in the adult Korean population.MethodsData from The Korea National Health and Nutrition Examination Survey, performed in Korea from 2007 to 2010, were used. In the survey, anthropometric data and blood samples were obtained during a fasting state. IR and β-cell function were calculated using the homeostasis model assessment (HOMA-IR and HOMA-β, respectvely.ResultsThe mean age of diabetes diagnosis was 58.5 years in women and was 55.1 years in men (P=0.015. The mean body mass index (BMI of newly diagnosed diabetes subjects was 26.1 kg/m2 in women and 25.0 kg/m2 in men (P=0.001. The BMI was inversely related to age in both genders, and the higher BMI in women than men was consistent throughout all age groups divided by decade. The HOMA-IR in women with diabetes is higher than in men with diabetes (7.25±0.77 vs. 5.20±0.32; P=0.012.ConclusionKorean adult women are diagnosed with type 2 diabetes at higher BMI and older age than men and are more insulin-resistant at the time of diabetes diagnosis. This may help explain why women with diabetes have an increased risk of developing cardiovascular disease after the diagnosis of diabetes, compared to men.

    Short stature, a marker for undernutrition early in life, has been associated with obesity in Brazilian women, but not in men. We tested the hypothesis that weight gain during the reproductive years could explain this gender difference. A national two-stage household survey of mothers with one or more children under five years of age was conducted in Brazil in 1996. The subjects were women aged 20 to 45 years (N = 2297), with last delivery seven months or more prior to the interview. The regions of the country were divided into rural, North/Northeast (urban underdeveloped) and South/Southeast/Midwest (urban developed). The dependent variables were current body mass index (BMI) measured, BMI prior to childbearing (reported), and BMI change. Socioeconomic variables included mother's years of education and family purchasing power score. A secondary analysis was restricted to primiparous women. The prevalence of current overweight and overweight prior to childbearing (BMI > or = 25 kg/m2) was higher among shorter women (parity, BMI prior to childbearing, and age at first birth, current BMI was 2.39 units higher (P = 0.008) for short stature women living in the urban developed area compared with short stature women living in the urban underdeveloped area. For both multiparous and primiparous women, BMI gain compared to the value prior to childbearing was significantly higher among short stature women living in the urban developed region (P <= 0.04). These results provide clear evidence that short stature was associated with a higher BMI and with an increased risk of weight gain/retention with pregnancy in the developed areas of Brazil, but not in the underdeveloped ones.

    Full Text Available Abstract Background The relationship between BMI and leptin has been studied extensively in the past, but previous reports in postmenopausal women have not been conducted under carefully controlled dietary conditions of weight maintenance using precise measures of body fat distribution. The aim of the present study was to examine the association between serum leptin concentration and adiposity as estimated by BMI and dual energy x-ray absorptiometry (DEXA measures (percent body fat, central and peripheral fat, and lean mass in postmenopausal women. Methods This study was conducted as a cross-sectional analysis within the control segment of a randomized, crossover trial in which postmenopausal women (n = 51 consumed 0 (control, 15 (one drink, and 30 (two drinks g alcohol (ethanol/d for 8 weeks as part of a controlled diet. BMIs were determined and DEXA scans were administered to the women during the 0 g alcohol treatment, and a blood sample was collected at baseline and week 8 of each study period for leptin analysis. Results and discussion In multivariate analysis, women who were overweight (BMI > 25 to ≤ 30 kg/m2 had a 2-fold increase, and obese women (BMI > 30 kg/m2 had more than a 3-fold increase in serum leptin concentrations compared to normal weight (BMI ≤25 kg/m2 women. When the models for the different measures of adiposity were assessed by multiple R2, models which included percent body fat explained the highest proportion (approximately 80% of the serum leptin variance. Conclusion Under carefully controlled dietary conditions, we confirm that higher levels of adiposity were associated with higher concentrations of serum leptin. It appears that percent body fat in postmenopausal women may be the best adiposity-related predictor of serum leptin.

    Maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) have been reported to be associated with pregnancy outcomes. Due to the nutrition transition in Thailand, the double burden of malnutrition is increasing and this may have negative consequences on birth outcomes. This study aimed to investigate the relationship between pre-pregnancy BMI and GWG with the risks of low birth weight and macrosomia. We performed a secondary analysis of data obtained from an iodine supplementation trial in mildly iodine-deficient Thai pregnant women. Pre-pregnancy BMI was classified using the WHO classification. GWG was categorized using the IOM recommendation. Binary and multinomial logistic regressions were performed. Among 378 pregnant women, the prevalence of pre-pregnancy underweight (BMI=25 kg/m2) were 17.2% and 14.3%, respectively. Normal weight women had the highest median GWG [15.0 (12.0, 19.0) kg] when compared to overweight women [13.2 (9.0, 16.3) kg]. Forty-one percent of women had excessive GWG, while 23% of women gained weight inadequately. Women with a high pre-pregnancy BMI had a 7-fold higher risk of having a macrosomic infant. Women who had excessive GWG were 8 times more likely to deliver a newborn with macrosomia. Both high pre-pregnancy maternal weight and excessive weight gain during pregnancy increase risk of infant macrosomia. Therefore, maintaining normal body weight before and throughout pregnancy should be recommended in order to reduce the risk of excessive infant birth weight and its associated complications.

    The knowledge of factors modulating the behaviour of bone mass is crucial for preventing and treating osteoporotic disease; among these factors, body weight (BW) has been shown to be of primary importance in postmenopausal women. Nevertheless, the relative effects of body composition indices are still being debated. Our aim was to analyze the relationship between body mass index (BMI), fat and lean mass and bone mineral density (BMD) in a large population of women. Moreover, this study represents a first important report on reference standard values for body composition in Italian women. Between 2005 and 2008, weight and height of 6,249 Italian women (aged 30-80 years) were measured and BMI was calculated; furthermore BMD, bone mineral content, fat and lean mass were measured by dual-energy X-ray absorptiometry. Individuals were divided into five groups by decades (group 1, 30.0-39.9; group 2, 40.0-49.9; group 3, 50.0-59.9; group 4, 60.0-69.9; group 5, 70.0-79.9). Differences among decades for all variables were calculated using a one-way analysis of variance (ANOVA) and Bonferroni test by the SPSS programme. Mean BW was 66.8±12.1 kg, mean height 159.1±6.3 cm and mean BMI 26.4±4.7 kg/m(2). According to BW and BMI, there was an increase of obesity with age, especially in women older than 50 years (posteoporosis in the examined population was 43.0% and 16.7%, respectively. Our data show that obesity significantly decreased the risk for osteoporosis but did not decrease the risk for osteopenia. It is strongly recommended that a strong policy regarding prevention of osteopenia and osteoporosis be commenced. An overall examination of our results suggests that both fat and lean body mass can influence bone mass and that their relative effect on bone could be modulated by their absolute amount and ratio to total BW.

    Physical inactivity is among the leading risk factors for non-communicable diseases. Saudi Arabia has just begun to address physical inactivity as recent studies have shown an alarming prevalence of insufficiently physically active adults. Saudi women are identified as among the most overweight/obese and least active worldwide. With an increase in the number of women in office based jobs, the risk of physical inactivity is likely to increase. Identifying the level and correlates for high BMI and physical inactivity in Saudi women will help to plan more effective public health strategies. The aim of this study is to assess the level of physical activity, inactivity and body mass index among Saudi women working in office based jobs in Riyadh city and identify the correlates for overweight, obesity and low physical activity. A cross- sectional study was conducted on 420 Saudi women aged 18 to 58 years working in office based jobs in eight worksites in Riyadh, Saudi Arabia. Body mass index was determined using weight and height measurements and physical activity was assessed based on a validated self-administered questionnaire. The majority of the subjects were overweight or obese (58.3 %). Overweight/obesity was associated with increased age, lower income and with those working in the public versus private sector. More than half of the sample (52.1 %) were insufficiently physically active. Participants working seven or more hours per day and those working in private versus public sector were significantly associated with low physical activity. This study identified Saudi women working in office based jobs as a high risk group for overweight, obesity and physical inactivity. As sedentary jobs may compound the risk for obesity and physical inactivity, this may support the use of workplace health programs to reduce sitting time and promote physical activity as a viable public health initiative.

    We showed that obese insulin resistant postmenopausal women are characterized by higher lean body mass and elevated C-reactive protein. Although counterintuitive, we hypothesized that losses in muscle mass following caloric restriction and increase in muscle quality will be associated with improvements in glucose homeostasis through decreases in C-reactive protein. To determine 1) if improvements in C-reactive protein concentrations occurs through losses in lean body mass; and 2) if decreases in C-reactive protein levels contribute to improvements in insulin sensitivity. 50 postmenopausal women (body mass index>26 kg/m(²)) with impaired glucose disposal (program. Outcome measures were: Glucose disposal rate: M value (by hyperinsulinemic-euglycemic clamp), body composition (total, trunk, and appendicluar). LBM and FM by DXA), LBM index (LBM (kg)/height (m(2)), body fat distribution (VAT and SAT by CT scan) and plasma high-sensitive C-reactive protein (hsCRP) and interleukin-6 (Il-6). Significant correlations were observed between Δ hsCRP levels with Δ Il-6 (r=0.33, p≤0.05), Δ total LBM index (r=0.44, p≤0.01), Δ trunk LBM (r=0.38, p≤0.01) Δ SAT (r=0.35, p≤0.05) and ∆ glucose disposal rate (r=- 0.44, p≤0.01). After including all the correlated variables in Stepwise linear regression model, Δ LBM index was the only independent predictor of the reduction in hsCRP levels (R(2)=0.20, p≤0.01). Losses in total lean body mass are independently associated with improvements in inflammatory state (CRP levels) in obese postmenopausal women with impaired glucose disposal. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available South African society consists of people who value honour, respect and dignity. One of the most worrying factors in our democratic country is the escalation of sex-related violations like rape, sexual harassment and sexual abuse. According to media reports, the rape and abuse of women are daily occurrences. Statistics also suggest that most marriages will at some point need to resolve the emotional trauma resulting from an extra-marital affair. It is imperative that whilst the police are trying to get the culprits into custody, we as a society should help to find out what has gone so wrong that the beautiful gift of a sexual relationship is being abused and degraded by the people. This delicate issue may be an indication of the influence of patriarchal systems in some African cultures. Rape statistics reveal that most of the perpetrators are well-known members of a community. There are many possible reasons why our society is facing this challenge; however, this study will explore the view that women are considered as sexual objects and how this perspective reveals itself as the cause of sexual offences.

    A decision to undertake screening for breast cancer often takes place within the primary care setting, but current controversies such as overdiagnosis and inconsistent screening recommendations based on evolving evidence render this a challenging process, particularly for average-risk women. Given the responsibility of primary care providers in counseling women in this decision-making process, it is important to understand their thoughts on these controversies and how they manage uncertainty in their practice. To review the perspectives and approaches of primary care providers regarding mammography decision-making with average-risk women. This study is a critical interpretive review of peer-review literature that reports primary care provider perspectives on mammography screening decision-making. Ovid MEDLINE®, Ovid PsycInfo, and Scopus databases were searched with dates from 2002 to 2017 using search terms related to mammography screening, uncertainty, counseling, decision-making, and primary health care providers. Nine articles were included following a review process involving the three authors. Using an inductive and iterative approach, data were grouped into four thematic categories: (1) perceptions on the effectiveness of screening, screening initiation age, and screening frequency; (2) factors guiding primary care providers in the screening decision-making process, including both provider and patient-related factors, (3) uncertainty faced by primary care providers regarding guidelines and screening discussions with their patients; and (4) informed decision-making with average-risk women, including factors that facilitate and hinder this process. The discussion of results addresses several factors about the diversity of perspectives and practices of physicians counseling average-risk women regarding breast cancer screening. This has implications for the challenge of understanding and explaining evidence, what should be shared with average-risk women

    Conflicting findings were reported on the body mass index (BMI)-based prognosis of critically patients. Errors in source weight and height data can confound BMI group allocation. The aim of the present work was to examine investigators' reporting on the methods of height and weight acquisition (HWA). PubMed and Embase databases were searched for studies describing BMI group-based risk of death in critically ill patients. Eligible studies were examined for reporting on (1) the use of measured and/or estimated HWA, (2) details of measuring devices, (3) device accuracy, and (4) methods of adjustment for acute and chronic fluid-related weight changes. Thirty studies met the eligibility criteria, including 159,565 patients. No data were provided in 13 studies (52% of reported patients) on whether estimates or measurements were used for HWA. Measured HWA was used exclusively in 6 studies (3% of patients), and an unspecified combination of estimated and/or measured HWA was reported for the remainder. Only 1 study reported the specific devices used. None of the studies provided data on the bias and precision of measuring devices. Adjustment for chronic and/or acute fluid-related weight changes was addressed in 2 studies for each. These findings demonstrate the prevalent risk for BMI group misallocation in the reviewed studies, which may confound BMI-based prognosis, raising concerns about the validity of reported BMI-related prognostic impact.

    Anti-Müllerian hormone (AMH) is a useful marker of ovarian reserve. Obesity/overweight are increasing and may affect the reproductive health. Previous studies regarding the effect of body mass index (BMI) on AMH levels are discordant. Our main goal was to evaluate the influence of BMI on AMH levels in women without polycystic ovarian syndrome. Revision of medical records of 951 women who performed AMH determinations as part of their fertility workup, between 2011 and 2016. Median AMH concentration was 1.75 [interquartile range (IQR) 2] ng/mL (12.9 pmol/mL) and median age at AMH determination was 35 (IQR 6) years. These women evidenced a median BMI of 23 (IQR 5) kg/m 2 . Caucasian women were more represented [889(89.3%)]. Smoking habits (present/past) were present in 359(36.1%), and 147(14.8%) harboured a history of ovarian surgery. On univariable analysis AMH was not correlated with BMI (r = 0.048/p = 0.135); the only factors influencing AMH were age (p ovarian surgery (p ovarian reserve. BMI does not seem to affect AMH levels. The reported concerns on infertility in overweight and obese women may be related to follicular development/oocyte maturation or endometrial disorders, rather than decreased ovarian reserve.

    Full Text Available Abstract Background Previous research has shown that underlying dietary patterns are related to the risk of many different adverse health outcomes, but the relationship of these underlying patterns to skeletal fragility is not well understood. The objective of the study was to determine whether dietary patterns in men (ages 25-49, 50+ and women (pre-menopause, post-menopause are related to femoral neck bone mineral density (BMD independently of other lifestyle variables, and whether this relationship is mediated by body mass index. Methods We performed an analysis of 1928 men and 4611 women participants in the Canadian Multicentre Osteoporosis Study, a randomly selected population-based longitudinal cohort. We determined dietary patterns based on the self-administered food frequency questionnaires in year 2 of the study (1997-99. Our primary outcome was BMD as measured by dual x-ray absorptiometry in year 5 of the study (2000-02. Results We identified two underlying dietary patterns using factor analysis and then derived factor scores. The first factor (nutrient dense was most strongly associated with intake of fruits, vegetables, and whole grains. The second factor (energy dense was most strongly associated with intake of soft drinks, potato chips and French fries, certain meats (hamburger, hot dog, lunch meat, bacon, and sausage, and certain desserts (doughnuts, chocolate, ice cream. The energy dense factor was associated with higher body mass index independent of other demographic and lifestyle factors, and body mass index was a strong independent predictor of BMD. Surprisingly, we did not find a similar positive association between diet and BMD. In fact, when adjusted for body mass index, each standard deviation increase in the energy dense score was associated with a BMD decrease of 0.009 (95% CI: 0.002, 0.016 g/cm2 for men 50+ years old and 0.004 (95% CI: 0.000, 0.008 g/cm2 for postmenopausal women. In contrast, for men 25-49 years old

    Disadvantaged communities provide adverse psychosocial exposures that have been linked to high levels of stress, and this may provide one explanatory pathway linking socioeconomic disadvantage to obesity. This study used hair cortisol analysis to quantify associations between stress and body mass index (BMI), and between hair cortisol and perceived psychological stress levels, in women and children living in socioeconomically disadvantaged neighborhoods. Participants were a volunteer sample of 70 women from the Resilience for Eating and Activity Despite Inequality study, including 30 maternal-child pairs. Women self-reported body weight, height and perceived psychological stress using the Perceived Stress Scale (PSS), and provided hair samples for themselves and their child. Children's body weight and height were measured. Following extraction, hair cortisol levels were measured using enzyme-linked immunosorbent assay. Multiple linear regression models examined associations between stress and BMI, and between hair cortisol and perceived stress levels in women and children. Women's hair cortisol levels were not associated with their BMI or PSS scores. Women's PSS scores were positively associated with their BMI (p = 0.015). Within maternal-child pairs, mothers and children's hair cortisol levels were strongly positively associated (p = 0.006). Maternal hair cortisol levels and PSS scores were unrelated to their child's zBMI. Children's hair cortisol levels were not associated with their zBMI or with their mother's PSS score. Findings suggest that cortisol-based and perceived psychological measures of stress may be distinct among women and children living in disadvantaged neighborhoods. Perceived psychological measures may be more important predictors of weight-related risk.

    Full Text Available The corporal image is the mental representation of the body that each individual builds. The dissatisfaction with the image and the corporal mass is closely associated to the self-esteem of the women. According to researches there are many concerned and insecure women in relation to their own shapes with a high index of corporal dissatisfaction, constituting a world problem. A high index of women goes to the physical activity and health consultation that Raúl Sánchez policlinic of Pinar del Río; offers many of them, for their dissent with the corporal weight. For this reason, we decide to carry out a research with the objective of determining the existent relationship between the CMI and the perception of the corporal image in women that attend to this consultation during the year 2014. It is a descriptive transverse study with a sample of 102 women older than 15 years old. They were carried out measured (weigh corporal and stature and a questionnaire was made to establish the grade of corporal dissatisfaction. It was used the questionnaire proposed by Stunkard, constituted by ten silhouettes for the feminine gender, numbered and ordained for the selection of one of them, that according to her perception and pleasure, it corresponded to her current corporal image and to how they wanted to be. The obtained data were tabulated and represented by means of charts. It was concluded that a high percent of these women is perceived incorrectly: 0,98% is undernourished and 62,8%, fatter; that the women with values of real CMI corresponding with normal weight and overweight are fatter than they really are, while the obese ones are perceived thinner; they consider that the pregnancies have been the main cause of the changes in the corporal weight and their grade of corporal dissatisfaction is based on 70,6% by their appearance before the society.

    To compare the prevalence of sarcopenia using two indicators: skeletal muscle mass index (SMI) and calf circumference (CC) used in the algorithm proposed by the European Working Group on Sarcopenia in Mexican elderly women. This was a cross-sectional study. Lean body mass was determined by dual-energy X-ray absorptiometry. To define sarcopenia, the SMI was obtained using a cut-off value of 5.5 kg/m 2 , and the CC cut-off was 31 cm. For gait speed and handgrip strength, the cut-off values were 0.8 m/s and 20 kg, respectively. A total of 137 women (mean age 73.8 ± 6.7 years) participated in the study. The prevalence of sarcopenia was 14.6% using SMI and 11.0% using CC (P = 0.009). Body mass index was associated with a lower probability of sarcopenia applying SMI or CC (OR 0.75, P = 0.002 for SMI and OR 0.71, P = 0.004 for CC). Sarcopenia evaluated either with dual-energy X-ray absorptiometry or CC was not associated with physical performance, such as five times chair stand test, timed up and go test and short physical performance battery. Additionally, SMI was not associated with physical performance, five times chair stand test (P = 0.775) and timed up-and-go test (P = 0.341). The prevalence of sarcopenia in active elderly women was low. A higher prevalence of sarcopenia was detected using SMI compared with CC. It is important to identify the best methods to assess skeletal muscle mass to obtain a reliable diagnosis of sarcopenia. Geriatr Gerontol Int 2017; 17: 161-170. © 2015 Japan Geriatrics Society.

    Available data reveals inconsistent relationships between eating behaviour traits and markers of adiposity level. It is thus relevant to investigate whether other factors also need to be considered when interpreting the relationship between eating behaviour traits and adiposity. The objective of this cross-sectional study was thus to examine whether the associations between variables of the Three-Factor Eating Questionnaire (TFEQ) and adiposity are influenced by the level of physical activity participation. Information from the TFEQ and physical activity was obtained from 113 postmenopausal women (56.7 ± 4.2 years; 28.5 ± 5.9 kg/m2). BMI was compared between four groups formed on the basis of the physical activity participation and eating behaviour traits medians. In groups of women with higher physical activity participation, BMI was significantly lower in women who presented higher dietary restraint when compared to women who had lower dietary restraint (25.5 ± 0.5 versus 30.3 ± 1.7 kg/m2, P < .05). In addition, among women with lower physical activity participation, BMI was significantly lower in women presenting a lower external hunger than in those with a higher external hunger (27.5 ± 0.8 versus 32.4 ± 1.1 kg/m2, P < .001). Our results suggest that physical activity participation should also be taken into account when interpreting the relationship between adiposity and eating behaviour traits. PMID:20871862

    Full Text Available The healthcare monitoring on a remote care taking base involves many implicit observations between the subjects and the care takers. Any deficit in domain knowledge and carelessness leads to unpleasant situations thereafter. A wearable attire system can precisely interpret the implicit communication of the state of the subject and pass it to the care takers or to an automated aid device. Casual and conventional movements of subjects during play and living condition can be used for the above purpose. The proposed system suggests a novel way of identifying safe and unsafe conditions of playing for the children where a rapid warning assistance is required. The same system is used in the case of the normal and contraction time identification of pregnant women. Naive Bayes classifier was applied on features created by different algorithms and on the combinations of features constructed by algorithms like Fractal Dimension, Fast Fourier Transformation, Singular Value Decomposition. The result shows in general that the combinational features with point system results in better classification. Especially the FFT and SVD were more supportive in all three sets of experiments and better classified by Navie Bayes classifier than the other combinations and individual features. But the complexity is high when going through the point system. When a priori based point system is introduced with a reduced complexity to replace the conventional point system, the enhanced results show a well-distinguished realization of different body movement activities using a wearable attire array and the interpretation consistently results in significant and identifiable thresholds.

    Adiponectin, a fat derived cytokine, is a potential independent contributor to bone mineral density (BMD); however, its action on bone metabolism in humans is still unclear. The aim of this study was to investigate the relationship of adiponectin with bone mass indices and bone metabolic markers in middle-aged post-menopausal women without diabetes. A random sample consisted of 81 post-menopausal women (age range 45-61 yr, osteopenic/osteoporotic no.=43) was studied. Lumbar-spine BMD (BMD(L2-L4)) and total-body bone mineral content (TBBMC) were measured with dual X-ray absorptiometry. Plasma levels of total and high-molecular weight (HMW) adiponectin, osteoprotegerin (OPG), soluble receptor activator of nuclear factor-κB ligand (sRANKL) and IGF-I were determined. No association was observed between total or HMW adiponectin and BMD(L2-L4) or TBBMC. On the contrary, adiponectin levels were positively associated with OPG levels (partial r=0.276, p=0.015) and negatively with IGF-I (partial r=-0.438, pfailed to show statistically significant association between circulating adiponectin levels and indices of bone mass in women during the postmenopausal period, we showed significant associations with OPG and IGF-I levels, suggesting an anabolic role of adiponectin, which may contribute in the understanding of the interplay between adipose tissue-derived hormones and bone metabolism. © 2012, Editrice Kurtis.

    The study sought to examine the gender-specific effects of physical activity level and body mass index on recovery from persistent neck pain (PNP) among citizens of working age in Stockholm, Sweden. A population-based cohort of 1,730 subjects (18-65) with PNP answered surveys in 2002 and 2007. Prognostic factors were self-reported body mass index (BMI) and physical activity level (PAL) at baseline. Analyses were performed with odds ratios (OR) with corresponding 95 % confidence intervals (95 % CI). Women reporting higher physical activity level had higher odds of recovering from PNP than women with sedentary leisure time (OR of 1.5, 95 % CI 1.0-2.4), but no associations were found in men. No associations were found between BMI and recovery from PNP in any analyses. Physical activity seems to be associated with recovery from PNP in women and should therefore be encouraged. Future studies should continue investigating physical activity and lifestyle factors in relation to recovery from persistent neck pain, since these modifiable factors may be considered in interventions.

    The American Indian/Alaska Native (AI/AN) population is a high-risk group across many health indicators, including fetal macrosomia. We aimed to investigate the effects of prepregnancy body mass index (BMI) and gestational weight gain (GWG) on macrosomia and explore possible racial and geographical variations among AI/AN women. This retrospective cohort study was conducted from the Pregnancy Risk Assessment Monitoring System in eight states (2004-2011) among live, singleton, term births to AI/AN women 20 years or older. Prevalence of macrosomia (birth weight ≥ 4000 g) by select characteristics were estimated; differences were assessed with Chi-squares. Multivariable logistic regression was conducted to calculate adjusted odds ratios (aOR) for effects on macrosomia of BMI and GWG (enumerating the pounds women deviated from the Institute of Medicine guidelines for GWG) controlling for other factors in the total sample and stratified by race and state of residence. The prevalence of macrosomia was 14 %, ranging from 8 to 21 % (Utah-Alaska). Among AI/AN women, 30 % were obese prepregnancy and 50 % had excess GWG. Significant independent effects were found for macrosomia of prepregnancy overweight (aOR 1.27; 95 % Confidence Interval 1.01-1.59), obesity (aOR 1.63; 1.29-2.07), and excess GWG (aOR 1.16; 1.13-1.20 per five pounds gained beyond appropriate). Adjusted estimates varied between race and state. Prepregnancy BMI and GWG are independent factors for macrosomia among AI/AN women. Future research should prioritize development, testing, and implementation of weight management programs, which account for variations among AI/AN women, both before and during pregnancy for BMI regulation and GWG control.

    The relationship between obesity and depression is well described. However, the evidence linking depression and body mass index (BMI) across the broad range of body size is less consistent. We examined the association between depressive symptoms and BMI in a sample of adult women in the Buffalo-Niagara region between 1997 and 2001. Using logistic regression, we investigated whether increased weight status beyond normal-weight was associated with a higher prevalence of depressive symptoms, and if educational attainment modified the association between obesity and depression. There was a trend for increased weight status to be associated with higher depressive symptoms (obese II/III, OR 1.57, 95% CI 1.03-2.41), whereas higher education was associated with lower odds of depressive symptoms, in an adjusted model including BMI (more than 12 but less than 16 years, OR 0.70, 95% CI 0.49-0.98; 16 or more years of education, OR 0.61, 95% CI 0.40-0.93). The association of being obese I with depressive symptoms was different for more educated (OR 2.15, 95% CI 1.27-3.62) compared to less educated women (OR 0.90, 95% CI 0.50-1.62); the sample was larger for the more educated women and reached statistical significance. There were no differences in the association for obese II/III women in strata of education. There was evidence of risk-difference heterogeneity (0.88, 95% CI 0.84-0.93). In this population-based sample of women in western New York state, increased weight was negligibly associated with depressive symptoms. The association of being obese I with depressive symptoms was different for more compared to less educated women. Copyright © 2016 Asia Oceania Association for the Study of Obesity.

    Our aim was to investigate the association between gestational weight gain (GWG) and postpartum weight retention (PWR) in pre-pregnancy underweight, normal weight, overweight or obese women, with emphasis on the American Institute of Medicine (IOM) recommendations. We performed secondary analyses on data based on questionnaires from 1,898 women from the "Smoke-free Newborn Study" conducted 1996-1999 at Hvidovre Hospital, Denmark. Relationship between GWG and PWR was examined according to BMI as a continuous variable and in four groups. Association between PWR and GWG according to IOM recommendations was tested by linear regression analysis and the association between PWR ≥ 5 kg (11 lbs) and GWG by logistic regression analysis. Mean GWG and mean PWR were constant for all BMI units until 26-27 kg/m(2). After this cut-off mean GWG and mean PWR decreased with increasing BMI. Nearly 40% of normal weight, 60% of overweight and 50% of obese women gained more than recommended during pregnancy. For normal weight and overweight women with GWG above recommendations the OR of gaining ≥ 5 kg (11 lbs) 1-year postpartum was 2.8 (95% CI 2.0-4.0) and 2.8 (95% CI 1.3-6.2, respectively) compared to women with GWG within recommendations. GWG above IOM recommendations significantly increases normal weight, overweight and obese women's risk of retaining weight 1 year after delivery. Health personnel face a challenge in prenatal counseling as 40-60% of these women gain more weight than recommended for their BMI. As GWG is potentially modifiable, our study should be followed by intervention studies focusing on GW.

    Breastfeeding can play a key role in the reduction of obesity, but initiation and maintenance rates in women with a body mass index (BMI) of ≥30 kg m -2 are low. Psychological factors influence breastfeeding behaviours in the general population, but their role is not yet understood in women with a BMI ≥30 kg m -2 . Therefore, this review aimed to systematically search and synthesize the literature, which has investigated the association between any psychological factor and breastfeeding behaviour in women with a BMI ≥30 kg m -2 . The search identified 20 eligible papers, reporting 16 psychological factors. Five psychological factors were associated with breastfeeding behaviours: intentions to breastfeed, belief in breast milk's nutritional adequacy and sufficiency, belief about other's infant feeding preferences, body image and social knowledge. It is therefore recommended that current care should encourage women to plan to breastfeed, provide corrective information for particular beliefs and address their body image and social knowledge. Recommendations for future research include further exploration of several psychological factors (i.e. expecting that breastfeeding will enhance weight loss, depression, anxiety and stress) and evidence and theory-based intervention development. © 2018 The Authors.

    Full Text Available Background: Poly cystic ovary syndrome (PCOS is considered one of the most common endocrine disorders of women in reproductive age. The aim of this study was evaluating the efficacy of calcium and Vitamin D supplementation on the regularity of menstrual cycles, body mass index (BMI and hyper androgenism state of women with PCOS. Materials and Methods: In this clinical trial, 80 women with PCOS were evaluated. They randomly located in four groups receiving metformin (group 1, metformin plus calcium and Vitamin D (group 2, calcium and Vitamin D (group 3 and placebo (group 4 for 4 months. BMI, regularity of menstrual cycles, hyperandrogenism (hirsutism and acne and serum calcium and Vitamin D levels were compared in four studying groups at baseline and 4 months after the trial. Results: All studied subjects were similar at baseline (P > 0.05. After trial, the frequency of hirsutism and acne were not different among groups. Frequency regular menstrual cycle and dominant follicle were significantly higher in group 1 and 2 than others (P < 0.05. After trial, there was no significant difference with respect to BMI among groups. Conclusion: Vitamin D and calcium supplementation in addition to metformin therapy in women with PCOS could result in a better outcome in a variety of PCOS symptoms including menstrual regularity, and ovulation.

    We examined the effects of sedentary lifestyle and dietary habits on body mass index (BMI) change in a follow-up study of 325 women (aged 15-49 years) in Delhi, systematically selected from the 1998-1999 National Family Health Survey samples who were re-interviewed after 4 years in 2003. Information was collected on height, weight, dietary habits, and sedentary lifestyle through face-to-face interviews. Overall, a 2.0-point increase in mean BMI was found among women in just 4 years. Every second normal-BMI woman, two in five overweight women, and every fourth obese woman experienced a > 2.0-point increase in her mean BMI. High sedentary lifestyle (OR: 2.63; 95% CI: 1.29-5.35) emerged as the main predictor of a > 2.0-point increase in mean BMI in adjusted analysis, but there was weak evidence of association with the dietary covariates. Our findings suggest that a high sedentary lifestyle is a determinant of weight gain among adult women in urban India.

    The purpose of this study was to characterize the relationship between changes in body mass index (BMI) and incident atrial fibrillation (AF) in a large cohort of women. Obesity and AF are increasing public health problems. The importance of dynamic obesity-associated AF risk is uncertain, and mediators are not well characterized. Cases of AF were confirmed by medical record review in 34,309 participants in the Women's Health Study. Baseline and updated measures of BMI were obtained from periodic questionnaires. During 12.9 +/- 1.9 years of follow-up, 834 AF events were confirmed. BMI was linearly associated with AF risk, with a 4.7% (95% confidence interval [CI]: 3.4 to 6.1, p WHS]: A Randomized Trial of Low-Dose Aspirin and Vitamin E in the Primary Prevention of Cardiovascular Disease and Cancer; NCT00000479).

    Normal-weight women frequently restrict their caloric intake and exercise, but little is known about the effects on body weight, body composition and metabolic adaptations in this population. We conducted a secondary analysis of data from a randomized controlled trial in sedentary normal-weight women. Women were assigned to a severe energy deficit (SEV: -1062±80 kcal per day; n=9), a moderate energy deficit (MOD: -633±71 kcal per day; n=7) or energy balance (BAL; n=9) while exercising five times per week for 3 months. Outcome variables included changes in body weight, body composition, resting metabolic rate (RMR) and metabolic hormones associated with energy conservation. Weight loss occurred in SEV (-3.7±0.9 kg, P0.33). RMR decreased by -6±2% in MOD (P=0.020). In SEV, RMR did not change on a group level (P=0.66), but participants whose RMR declined lost more weight (P=0.020) and had a higher baseline RMR (P=0.026) than those whose RMR did not decrease. Characteristic changes in leptin (P=0.003), tri-iodothyronine (P=0.013), insulin-like growth factor-1 (P=0.016) and ghrelin (P=0.049) occurred only in SEV. The energy deficit and adaptive changes in RMR explained 54% of the observed weight loss. In normal-weight women, caloric restriction and exercise resulted in less-than-predicted weight loss. In contrast to previous literature, weight loss consisted almost exclusively of fat mass, whereas fat-free mass was preserved.

    Although it has been well-documented that obesity is associated with decreased risk of premenopausal breast cancer and increased risk of postmenopausal breast cancer, it is unclear whether these associations differ among breast cancer subtypes defined by the tumor protein expression status of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). We evaluated the associations of body mass index (BMI) at age 18 years and recent BMI in relation to risk of breast cancer overall and ER/PR/HER2-defined subtypes, in 6320 women (3934 case-patient participants, 2386 control participants) aged 35-64 years, who participated in one of three population-based case-control studies. We estimated multivariable-adjusted odd ratios (ORs) and corresponding 95% confidence intervals (CIs) using polychotomous unconditional logistic regression methods for case-control comparisons in premenopausal women and postmenopausal women. BMI at age 18 years was inversely associated with risk of breast cancer, particularly among premenopausal women (≥ 25 vs. women, African-American women). Recent BMI was not associated with risk of premenopausal breast cancer after adjustment for BMI at age 18 years; nevertheless, the analysis for the joint effects of BMI at age 18 years and recent BMI showed that premenopausal women in the highest categories of the two BMI measures (≥ 25 kg/m 2 at age 18 years and ≥ 30 kg/m 2 for recent BMI) had 46% lower risk of breast cancer than premenopausal women in the lowest categories of the two BMI measures (breast cancer. Our findings indicate that high BMI near the end of adolescence decreases risk of all ER/PR/HER2-defined subtypes of premenopausal breast cancer and also suggest that this benefit could be maximized among premenopausal women who consistently have high BMI during their premenopausal years.

    Full Text Available Neste texto realizamos um exercício teórico estudando a situação de homens que cometem violência contra mulheres. Buscando pesquisar como as pessoas se posicionam e são posicionadas em práticas de poder e jogos de verdade, pressupomos ser imprescindível compreender os recursos discursivos e não-discursivos que instauram, constroem e mantêm uma prática, no caso a de violência às mulheres. Colocamos em discussão a atenção dada aos homens autores de violência nas diretrizes governamentais, dando ênfase a Lei Maria da Penha, concluindo que temos em jogo duas direções de análises e intervenções que se imbricam: por um lado, discussões e manifestações que incluem homens e mulheres, difundindo críticas ao modelo hegemônico sexista, por meio de produções artísticas, jornalísticas, publicitárias, conferências, pesquisas etc.; por outro lado, ações de mobilização voltadas para os "agentes sociais" que já atuam nas situações de violência contra a mulher para que mudem a perspectiva de suas intervenções, dando também atenção aos homens.In this text, we performed a theoretical exercise by focusing our analysis on the men who commit violence against women. In order to understand how people situate themselves and are situated within empowerment practices and truth games, we think that is absolutely essential to comprehend the narrative and the non-narrative resources that install, create and maintain any given practice, such as the violence against women. The goal of the study is to discuss the attention paid to the men who commit violence considering the government policies with special emphasis to the "Maria da Penha" Law. We concluded that there are two directions of analyses and interventions that are interconnected, such as: on one hand, there are forums and demonstrations that involve men and women spreading criticisms to the hegemonic sexist model through artistic, media, publicity, conferences, research

    To evaluate and compare the effectiveness of three different noninvasive treatment techniques on fat mass and regional fat thickness of the patients with cellulites. Sixty subjects were randomized into three groups. Group 1 (n = 20) treated with mechanical massage (MM), group 2 (n = 20) treated with manual lymphatic drainage (MLD) and group 3 (n = 20) treated with connective tissue manipulation (CTM) techniques. Subjects were evaluated by using standardized photographs, body composition analyzer (TBF 300) (body weight (BW), body mass index (BMI), fat %, fat mass (FM), fat free mass (FFM), total body water (TBW)), circumference measurement from thigh, waist-hip ratio (WHR), fat thickness measurements from abdomen, suprailium and thigh regions with skin fold caliper. All groups had an improvement in thinning of the subcutaneous fat after the treatment (P techniques are effective in decreasing the regional fat values of the patients with cellulites.

    In accordance with the sociocultural model, race/ethnicity is considered a major influence on factors associated with body image and body dissatisfaction, and eating disorders are often characterized as problems that are primarily limited to young White women from Western cultures. The purpose of this study was to determine whether there are differences that exist by race in desired body weight; the importance placed on those ideals; and dieting strategies among White, Asian American, Native Hawaiian/Pacific Islanders, and other mixed-race young women in Hawai'i. A total of 144 female college students 18-20 years of age were surveyed about body weight as well as eating and exercise habits. Results demonstrated that all the young women wanted to lose weight. However, there were no differences in desired body weight or desired weight change by race after controlling for body mass index suggesting that current weight rather than race/ethnicity is the predominant influence on weight-related concerns. Young White women placed the greatest level of importance on achieving a lower body weight, which corresponded with a greater likelihood to be attempting weight loss (dieting) and greater endorsement of behaviors consistent with weight loss compared to their counterparts. Findings imply that, for young women, race/ethnicity may not have as significant an impact on factors associated with body weight ideals as previously believed. Rather, differences in the value placed on achieving a desired body weight, as it relates to disordered eating, should be further explored among race/ethnic groups.

  8. High-molecular-weight adiponectin is selectively reduced in women with polycystic ovary syndrome independent of body mass index and severity of insulin resistance.

    2010-03-01

    Context: High-molecular-weight (HMW) adiponectin contributes to insulin resistance (IR), which is closely associated with the pathophysiology of polycystic ovary syndrome (PCOS). Abnormalities in adipocyte function have been identified in PCOS and potentially contribute to lower adiponectin concentrations. Objective: Our objective was to determine which variables in plasma and adipose tissue influence HMW adiponectin in a well characterized cohort of women with PCOS. Design: This was a cross-sectional study. Settings and Participants: A teaching hospital. Women with PCOS (n = 98) and body mass index (BMI)-matched controls (n = 103) (including 68 age-, BMI-, and IR-matched pairs). Interventions: A standard 75-g oral glucose tolerance test was performed for each participant. Subcutaneous adipose tissue samples were taken by needle biopsy for a subset of PCOS women (n = 9) and controls (n = 8). Main Outcome Measures: Serum levels of HMW adiponectin and their relation to indices of insulin sensitivity, body composition, and circulating androgens as well as adipose tissue expression levels of ADIPOQ, TNFalpha, PPARgamma, and AR were assessed. Results: HMW adiponectin was significantly lower in women with PCOS compared with both BMI- and BMI- and IR-matched controls (P = 0.009 and P = 0.027, respectively). Although BMI and IR were the main predictors of HMW adiponectin, an interaction between waist to hip ratio and plasma testosterone contributed to its variance (P = 0.026). Adipose tissue gene expression analysis demonstrated that AR and TNFalpha (P = 0.008 and P = 0.035, respectively) but not ADIPOQ mRNA levels were increased in PCOS compared with controls. Conclusions: HMW adiponectin is selectively reduced in women with PCOS, independent of BMI and IR. Gene expression analysis suggests that posttranscriptional\\/translational modification contributes to reduced HMW adiponectin in PCOS.

    Maternal obesity in pregnancy has been linked with increased risk of pregnancy induced hypertension (PIH). In some tertiary referral hospitals in Ghana, PIH is the leading cause of institutional maternal mortality. To evaluate blood pressure changes during pregnancy amongst different body mass index (BMI) groups and how this relates to the risk of developing PIH. Women who had a dating ultrasound before 20 weeks gestation and registering for antenatal care at the Korle-Bu Teaching Hospital in Accra, between February and December 2013 and met the inclusion criteria were recruited into a cohort study. BMI was assessed at baseline. Blood pressure measurements were taken at (±2) 24, 28 and 36 weeks. Primary outcome measure of interest during follow-up was a diagnosis of PIH at these points. BP changes during follow up at the three points were measured. Descriptive analysis of baseline factors was carried out and compared for the BMI groups. Relative risk (RR) of PIH was estimated at 95% confidence interval. Mean (SD) age for the 361 women was 30.9 (4.8) years. Incidence of PIH amongst the cohort was 10.5% (95% CI: 7.45% - 14.45%) and 40.4% and 33.0% of them were overweight and obese respectively at baseline. Pregnant women who were obese at baseline had a three-fold increased risk of PIH compared to those with normal BMI [RR = 3.01 (1.06-8.52), p = 0.04]. Obese women have a significantly increased risk of PIH. Women should be screened at booking for obesity status. Antenatal protocols should have interventions for prevention or early detection of obesity and management of obesity to improve outcomes.

    Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

    This study examined the association between the body mass index (BMI) in late adolescence and the risk of colon and rectal cancer. This study analyzed a cohort of 1,087,358 Jewish men and 707,212 Jewish women who underwent health examinations at the ages of 16 to 19 years between 1967 and 2002 and were followed by linkage to the national cancer registry up to 2012. Cox regression was used to estimate hazard ratios (HRs) for cancer according to age- and sex-adjusted BMI percentiles from the US Centers for Disease Control and Prevention (overweight, 85th percentile to cancer, including 1977 among men (1403 in the colon and 574 in the rectum) and 990 among women (764 in the colon and 226 in the rectum), were identified. Overweight and obesity were associated with the risk for colon cancer among both men (HR for overweight, 1.53; 95% confidence interval [CI], 1.28-1.84; HR for obesity, 1.54; 95% CI, 1.15-2.06; statistically significant from a BMI of 23.4 kg/m 2 [spline analysis]) and women (HR for overweight, 1.54; 95% CI, 1.22-1.93; HR for obesity, 1.51; 95% CI, 0.89-2.57; significant from a BMI of 23.6 kg/m 2 ). Obesity, but not overweight, was associated with a risk for rectal cancer among men (HR, 1.71; 95% CI, 1.11-2.65; significant from a BMI of 29.6 kg/m 2 ) and women (HR, 2.03; 95% CI, 0.90-4.58; significant from a BMI of 30.6 kg/m 2 ). Being overweight or obese in adolescence was associated with an increased risk of subsequent colon cancers in men and women, whereas obesity was associated with rectal cancer.

    To identify the impact of body mass index (BMI) and Western advertising and media on the stage of the nutrition transition among Jordanian women, and to evaluate their impact on eating styles and body image. A randomised cross-sectional survey that included a variety of culturally measured Likert-type scales and body size images. In addition, BMI was calculated based on measured height and weight. In the homes of the participants. The data were collected by female interviewers who worked for the Jordan Department of Statistics. The sample was based on a random and representative selection of 800 mostly urban Jordanian women. A pre-test sample of 100 women was also used to validate the instruments. Women tended to agree that they ate based on emotional cues. They had high levels of disordered eating attitudes and behaviours and 42.1% were considered restrained eaters. However, these women also had higher than expected body esteem levels and desired a healthy body size. As expected, being obese was associated with a desire to lose weight, being a restrained and emotional eater, and having more disordered eating attitudes and behaviours. Similarly, Western advertising and media were associated with restrained and emotional eating, desired weight loss, and disordered eating attitudes and behaviours. There is a need to develop health education materials that explain the influence of obesity on health and the negative psychological and physical consequences of restrained and emotional eating, building on the current cultural preferences of healthy body size. Further implications and suggestions for future research are discussed.

    The purpose of this investigation was to compare valgus/varus knee angles during various jumps and lower body strength between males and females relative to body mass. Seventeen recreationally active females (age: 21.94 ± 2.59 years; height: 1.67 ± 0.05 m; mass: 64.42 ± 8.39 kg; percent body fat: 26.89 ± 6.26%; squat one-repetition maximum: 66.18 ± 19.47 kg; squat to body mass ratio: 1.03 ± 0.28) and 13 recreationally active males (age: 21.69 ± 1.65 years; height: 1.77 ± 0.07 m; mass: 72.39 ± 9.23 kg; percent body fat: 13.15 ± 5.18%; squat one-repetition maximum: 115.77 ± 30.40 kg; squat to body mass ratio: 1.59 ± 0.31) performed a one-repetition maximum in the squat and three of each of the following jumps: countermovement jump, 30 cm drop jump, 45 cm drop jump, and 60 cm drop jump. Knee angles were analysed using videography and body composition was analysed by dual-energy X-ray absorptiometry to allow for squat to body mass ratio and squat to fat free mass ratio to be calculated. Significant differences (P ≤ 0.05) were found between male and female one-repetition maximum, male and female squat to body mass ratio, and male and female squat to fat free mass ratio. Significant differences were found between male and female varus/valgus knee positions during maximum flexion of the right and left leg in the countermovement jump, drop jump from 30 cm, drop jump from 45 cm, and drop jump from 60 cm. Correlations between varus/valgus knee angles and squat to body mass ratio for all jumps displayed moderate, non-significant relationships (countermovement jump: r = 0.445; drop jump from 30 cm: r = 0.448; drop jump from 45 cm: r = 0.449; drop jump from 60 cm: r = 0.439). In conclusion, males and females have significantly different lower body strength and varus/valgus knee position when landing from jumps.

    To provide recommendations and standard operating procedures for intensive care unit (ICU) and hospital preparations for a mass disaster or influenza epidemic with a specific focus on surge capacity and infrastructure considerations. Based on a literature review and expert opinion, a Delphi process was used to define the essential topics including surge capacity and infrastructure considerations. Key recommendations include: (1) hospitals should increase their ICU beds to the maximal extent by expanding ICU capacity and expanding ICUs into other areas; (2) hospitals should have appropriate beds and monitors for these expansion areas; hospitals should develop contingency plans at the facility and government (local, state, provincial, national) levels to provide additional ventilators; (3) hospitals should develop a phased staffing plan (nursing and physician) for ICUs that provides sufficient patient care supervision during contingency and crisis situations; (4) hospitals should provide expert input to the emergency management personnel at the hospital both during planning for surge capacity as well as during response; (5) hospitals should assure that adequate infrastructure support is present to support critical care activities; (6) hospitals should prioritize locations for expansion by expanding existing ICUs, using postanesthesia care units and emergency departments to capacity, then step-down units, large procedure suites, telemetry units and finally hospital wards. Judicious planning and adoption of protocols for surge capacity and infrastructure considerations are necessary to optimize outcomes during a pandemic.

    The issue of cultural universality of waist-to-hip ratio (WHR) attractiveness in women is currently under debate. We tested men's preferences for female WHR in traditional society of Tsimane'(Native Amazonians) of the Bolivian rainforest (N = 66). Previous studies showed preferences for high WHR in traditional populations, but they did not control for the women's body mass.We used a method of stimulus creation that enabled us to overcome this problem. We found that WHR lower than the average WHR in the population is preferred independent of cultural conditions. Our participants preferred the silhouettes of low WHR, but high body mass index (BMI), which might suggest that previous results could be an artifact related to employed stimuli. We found also that preferences for female BMI are changeable and depend on environmental conditions and probably acculturation (distance from the city). Interestingly, the Tsimane' men did not associate female WHR with age, health, physical strength or fertility. This suggests that men do not have to be aware of the benefits associated with certain body proportions - an issue that requires further investigation.

    We examined risk factors for posttrauma symptomatology, 2 and 6 months following the April 2007 mass shooting at Virginia Tech. Using a conservation of resources framework and a Web-based survey methodology, we prospectively evaluated the relations among preshooting distress, social support, resource loss, and posttrauma symptomatology in a sample of 293 female students enrolled at the university at the time of the shootings. Structural equation modeling supported that preshooting social support and distress predicted resource loss postshooting. Resource loss predicted symptomatology 2 months and 6 months after the shooting. Implications of the results for research and intervention following mass trauma are discussed.

    It has been suggested that physical activity may affect weight reduction outcomes through associated improvements in mood. Relations of physical activity, mood, and weight change are not well understood in persons classified as severely obese (BMI > or = 40 kg/m(2)), however. This research tested these relationships in women with severe obesity. 57 women with a mean BMI of 43.8 kg/m(2) were enrolled in a cognitive-behavioral exercise support treatment with group-based nutrition information. Measurement of depression, tension, overall mood, and BMI was taken at baseline and month 6, and exercise session attendance was recorded. The treatment was associated with significant improvements in depression, tension and total mood disturbance scores as well as in BMI over 6 months. Changes in mood scores that were more positive were correlated with a greater reduction in BMI. Mean attendance in the prescribed 3 session/week exercise regimen was 46.0%, and attendance was significantly correlated with changes in tension and total mood disturbance scores, and approached significance with changes in depression scores. Findings suggested significant relations of mood and weight change as well as of physical activity and mood in severely obese women associated with a treatment of moderate physical activity. With extensions of this research, weight loss theory and treatment may benefit. Copyright 2008 S. Karger AG, Basel.

    Full Text Available Maya Laxmi Patel, Raywat Deonandan Interdisciplinary School of Health Sciences, University of Ottawa, Ottawa, ON, Canada Background: Urbanization is increasing around the world, and in India, this trend has translated into an increase in the size of slum dwellings whose environments are suspected of being associated with poor health outcomes, particularly those relating to women’s nutritional status. With this study, we sought to determine the factors associated with Indian women’s body mass index (BMI in slum environments, with special attention paid to women with tribal status.Methods: A multiple linear regression analysis was performed on data from the Indian National Family Health Survey (2005–2006, modeling demographic and behavioral factors suspected of being associated with BMI, with additional focus on the measures of social class, specifically caste and tribal status.Results: Increasing BMI is significantly and positively associated with frequency of watching television, having diabetes, age, wealth index, and residency status in the areas of New Delhi, Andhra Pradesh, or Tamil Nadu.Conclusion: Although belonging to a scheduled tribe was not associated with changes in BMI, unadjusted rates suggest that tribal status may be worthy of deeper investigation. Among slum dwellers, there is a double burden of undernutrition and overnutrition. Therefore, a diverse set of interventions may be required to improve the health outcomes of these women.

    This study aims to examine the independent and combined impact of hypocaloric diet and low-intensity resistance exercise training (LIRET) on aortic hemodynamics and appendicular skeletal muscle mass (ASM) in obese postmenopausal women. Forty-one obese postmenopausal women (mean [SD] age, 54 [1] y) were randomly assigned to LIRET (n = 13), diet (n = 14), or diet + LIRET (n = 14). Body weight, waist circumference, aortic systolic blood pressure, aortic pulse pressure, augmentation index, subendocardial viability ratio (SEVR; myocardial perfusion), and heart rate (HR) were measured before and after 12 weeks. ASM was assessed by dual-energy x-ray absorptiometry. Body weight (P diet and diet + LIRET compared with no changes after LIRET. ASM did not change after diet + LIRET, and the decrease observed after diet (P diet (P diet + LIRET (P diet and diet + LIRET, but not after LIRET. SEVR (P diet groups, whereas HR (P diet. Changes in SEVR (P diet were different compared with LIRET. The augmentation index did not change in any group. Our findings suggest that diet-induced weight loss may reduce cardiovascular risk by improving SEVR via HR and aortic pulse pressure reductions in obese postmenopausal women. LIRET prevents ASM loss associated with hypocaloric diet but has no additive effects on aortic hemodynamics.

    AIM: To investigate if vitamin D receptor (VDR) gene Apa I polymorphism and estrogen receptor-α (ER-α) gene Pvu II, Xba I polymorphisms are related to bone mineral density (BMD), bone mineral content (BMC) and bone size in premenopausal Chinese women. METHODS: The VDR Apa I genotype and ER-α Pvu II, Xba I genotype were determined by PCR-restriction fragment length polymorphism (RFLP) in 493 unrelated healthy women aged 20-40 years of Hah nationality in Shanghai city. BMD (g/cm2), BMC (g), and bone areal size (BAS, cm2) at lumbar spine 1-4 (L1-4) and proximal femur (femoral neck, trochanter and Ward's triangle) were measured by duel-energy X-ray absorptionmetry. RESULTS: All allele frequencies did not deviate from Hardy-Weinberg equilibrium. After phenotypes were adjusted for age, height, and weight, a significant association was found between VDR Apa I genotype and BMC variation at L1-4 and Ward's triangle (P<0.05), but not in BMD or BAS at lumbar spine and proximal femur.ER-α Pvu II, Xba I genotype was not related to BMC, BMD, and BAS at all sites. CONCLUSION: The study suggested that Apa I polymorphism in VDR gene may influence on attainment and maintenance of peak bone mass in premenopausal Chinese women.

    Recently, importance of evaluation for impact of earthquake-induced slope failure on nearby critical structures is increasing in order to evaluate seismic stability of the slope, in addition to evaluating the possibilities of slope failure. In this study, we presented an examination flow chart to evaluate the impact on structures after slope failure. In the examination flow chart, we assumed the following four considerations; (1) evaluation of the collapse region of the slope, (2) evaluation of behavior of the collapsed rock masses, (3) evaluation of the impact on the structures, (4) examination of the countermeasures. And, for the purpose of using three dimensional distinct element method (DEM) for evaluation of behavior of the collapsed rock masses, we firstly confirmed applicability of DEM to behavior of a mass hurtling down the slope by means of comparing with the model test results. Moreover, we clarified influence of initial position or restitution coefficient of rock masses on final traveling distance of collapsed rock masses. (author)

    Full Text Available BACKGROUND: Body image satisfaction (BIS influences body weight regulation and may contribute to long-term healthier lifestyle after pregnancy. Thus, we aimed to assess the association between BIS before pregnancy and body mass index (BMI 4 years after the index pregnancy. METHODS: As part of the follow-up of a birth cohort, 3612 women with prepregnancy BMI >18.5 kg/m(2 were reevaluated 4 years after the birth of a child. BIS was defined as the difference between perceived and ideal body size before pregnancy, assessed by Stunkard Silhouettes after birth. The associations of BIS with BMI change (continuous and BMI classes at 4 years, based on measured weight and height, were estimated using linear and multinomial regression, respectively. RESULTS: Among women with normal prepregnancy BMI, those who felt too small, regarding their ideal, had a 0.25 kg/m(2 smaller increase in BMI within 4 years and a lower likelihood of becoming overweight or obese [multivariate-adjusted odds ratio (OR = 0.63; 95% confidence interval (95%CI: 0.44-0.91 and OR = 0.21; 95%CI: 0.05-0.91, respectively than those satisfied with body image. Feeling too large was associated with a 0.41 kg/m(2 larger increase in BMI and a higher risk of becoming overweight or obese (OR = 2.12; 95%CI:1.73-2.59 and OR = 3.42; 95%CI:2.02-5.79, respectively. A similar, non-significant, trend was observed for overweight women. Obese women who felt too large had a non-significant decrease in BMI. CONCLUSIONS: BIS plays a role in maternal body weight after delivery. Realistic body size goals may promote the motivation to lose weight and contribute to higher success in attaining them.

    Full Text Available Abstract Background Body mass index (BMI is often used as an objective surrogate estimate of body fat. Increased BMI is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus (T2DM. The Stunkard Figure Rating Scale (FRS is a subjective measure of body fat, and self-perceptions of body image conceivably impact the development and treatment of T2DM. This study examined the self-perception of body image to various levels of BMI among those with T2DM. Methods Respondents (n = 13,887 to the US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD 2006 survey self-reported their weight and height for BMI calculation. On the gender-specific Stunkard FRS, respondents selected the figure most closely resembling their body image. Spearman correlation was computed between perceived body image and BMI for men and women separately. Student's t-test analysis compared the mean BMI differences between respondents with and without T2DM. Results Men with T2DM did not significantly differ from men without diabetes mellitus in mean BMI per body image figure except at the extremes in body figures. Women with T2DM had a significantly higher BMI for the same body figure compared with women without diabetes mellitus for most figures (p Conclusions Individuals, particularly women, with T2DM may differ in their perception of body image compared with those without diabetes mellitus. It is unclear if these perceived differences increase the risk of T2DM, or if the diagnosis of T2DM alters body image perceptions.

    maternal obesity [body mass index (BMI)≥30kg/m(2)] is a cause for concern because of increasing rates and risk of associated complications. However, little is known about how to improve the health of women with a BMI≥30kg/m(2). a 10-week antenatal lifestyle programme (The Lifestyle Course - TLC), underpinned by behaviour change theory, was developed in a programme of research which included a prospective, multicentred, feasibility phase (n=227). Participants had a BMI≥30kg/m(2) at the start of their pregnancy, planned to deliver in two areas of Greater Manchester and were aged 18 or over. The objectives were to (1) assess the feasibility of the intervention and (2) to pilot the trial processes and outcome measures. (1) Trial intervention: only 22% of women in the feasibility phase had received gestational weight advice prior to the study. One or more TLC sessions were attended by 79% of women and 97% said they would recommend TLC to a friend due to the content suitability, perceived personal gains and extra care received. Changes to the TLC were suggested and implemented in the pilot phase. (2) Trial processes: recruitment rates (36%), retention rates (100%) and questionnaire completion rates up to one year (33%) were found. Daily general 'lifestyle' diaries and pedometers were not acceptable data collection tools (response rates of 32% and 16% respectively). However, specific food diaries were acceptable (response rates of 80-81%). The major challenge was the collection of maternal weight data at the follow-up points. the antenatal intervention (TLC) designed for this programme of work appears to suit the needs of women with a BMI≥30kg/m(2). The need for an antenatal intervention is clear from this study and also highlights reflections on effective communication with pregnant women with a BMI≥30kg/m(2). Lessons learnt for designing a future trial include effective ways to communicate with pregnant women with a BMI≥30kg/m(2). ISRCTN29860479. Copyright

    Polycystic ovary syndrome (PCOS) has clinical features and implications for long-term health that may lead to decreased quality of life (QoL) and psychological morbidity. We studied QoL in women with PCOS, compared the findings with population norms and assessed whether they correlated with reported quality of patient information received. Cross-sectional study. Women with PCOS by National Institutes of Health (NIH) criteria, diagnosis confirmed by one endocrinologist. Four questionnaires were mailed: the Short Form-36 (SF-36), the Quality-of-Life Questionnaire for Women with Polycystic Ovary Syndrome (PCOSQ), the General Health Questionnaire-28 (GHQ-28) and an assessment of information quality and sources, the Patient Information Questionnaire (PIQ). Questionnaires were sent to 443 women with PCOS from one endocrinologist's database; 203 women aged 15-65 years agreed to participate. To compare with Australian population norms, data from those women aged 18-44 years (n = 173) were used. Of these, 64% were obese, 18% overweight and 18% of normal weight. The demographics, socioeconomic status and untreated biochemistry of the responders and the total patient group were not significantly different. SF-36 scores were significantly lower than the age- and sex-matched Australian population (P PCOSQ was similar to other published studies. GHQ-28 identified psychological morbidity in 62.4%, compared with 26.4% in a matched Australian population (P < 0.0001). Body mass index (BMI) was negatively correlated with QoL (P < 0.01). There was a positive association between the psychological domain of QoL and the subjective assessment of the quality of health-related information in general (P < 0.001), for hirsutism (P < 0.01) and for menstrual irregularity (P < 0.05). We have shown impaired QoL and increased prevalence of psychological morbidity in PCOS compared with population norms. The perception of inadequate information about the condition correlated with poorer QoL scores

    To evaluate whether a culturally appropriate campaign using "Black radio" and print media increased awareness and utilization of local mammography screening services provided by the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program among African American women. The evaluation used a quasi-experimental design involving data collection during and after campaign implementation in two intervention sites in GA (Savannah with radio and print media and Macon with radio only) and one comparison site (Columbus, GA). We used descriptive statistics to compare mammography uptake for African American women during the initial months of the campaign (8/08-1/09) with the latter months (2/09-8/09) and a post-campaign (9/09-12/09) period in each of the study sites. Comparisons of monthly mammogram uptake between cities were performed with multinomial logistic regression. We assumed a p value campaign to the later period. However, the increase did not persist in the post-campaign period. Analysis comparing monthly mammogram uptake in Savannah and Macon with Columbus showed a significant increase in uptake from the first to the second period in Savannah only (OR 1.269, 95 % CI (1.005-1.602), p = 0.0449). Dissemination of health promotion messages via a culturally appropriate, multicomponent campaign using Black radio and print media was effective in increasing mammogram uptake in Savannah among low-income, African American women. Additional research is needed to quantify the relative contribution of campaign radio, print media, and community components to sustain increased mammography uptake.

    Influences of dietary patterns on musculoskeletal health are poorly understood in middle-aged women. This cross-sectional analysis from a cohort of 347 women (aged 36-57 years) aimed to examine associations between dietary patterns and musculoskeletal health outcomes in middle-aged women. Diet was measured by the Cancer Council of Victoria FFQ. Total body bone mineral content (TB BMC), femoral neck and lumbar spine bone density (dual-energy X-ray absorptiometry), lower limbs muscle strength (LMS) and balance tests (timed up and go test, step test, functional reach test (FRT) and lateral reach test) were also measured. Exploratory factor analysis was used to identify dietary patterns and scores for each pattern generated using factor loadings with absolute values ≥0·20. Associations between food pattern scores and musculoskeletal outcomes were assessed using multivariable linear regression. Three dietary patterns were identified: 'Healthy' (high consumption of a plant-based diet - vegetables, legumes, fruit, tomatoes, nuts, snacks, garlic, whole grains and low intake of high-fat dairy products), 'high protein, high fat' (red meats, poultry, processed meats, potatoes, cruciferous and dark-yellow vegetables, fish, chips, spirits and high-fat dairy products) and 'Processed foods' (high intakes of meat pies, hamburgers, beer, sweets, fruit juice, processed meats, snacks, spirits, pizza and low intake of cruciferous vegetables). After adjustment for confounders, Healthy pattern was positively associated with LMS, whereas Processed foods pattern was inversely associated with TB BMC and FRT. The associations were not significant after accounting for multiple comparisons. There were no associations with any other outcomes. These results suggest that maintaining a healthy diet could contribute to bone acquisition, muscle strength and balance in adult life. However, while they provide some support for further investigating dietary strategies for prevention of age

PBF and fat-free mass (FFM were determined by dual energy X-ray absorptiometry. The investigated inflammatory parameters were interleukin 6 and C-reactive protein.Results: Twenty-five percent of the elderly women were classified as normal weight, 50% overweight, and 25% obese by the BMI. The obese group had higher levels of triglycerides and very low-density lipoproteins than did the normal weight group (P≤0.05 and lower levels of high-density lipoproteins (HDL than did the overweight group (P≤0.05. According to the PBF, 49% of the elderly women were classified as eutrophic, 28% overweight, and 23% obese. In the binomial logistic regression analyses including age, FFM, and lipid profile, only FFM (odds ratio [OR]=0.809, 95% confidence interval [CI]: 0.739–0.886; P<0.0005 proved to be a predictor of reaching the eutrophic state by the BMI.

    Marital status has been recognized as a significant health-influencing factor, including cardiovascular disease (CVD) risk. The aim of the present paper was to evaluate whether eating habits mediate the relationship between marital status and levels of CVD risk factors among apparently healthy men and women from the ATTICA Study. During 2001-2002, we randomly enrolled 1514 men (18-87 years old) and 1528 women (18-89 years old) from the Attica area, Greece; the sampling was stratified by the age-gender distribution of the region. Participants underwent clinical, anthropometric and psychological assessment. Food consumption was assessed through a semi-quantitative food frequency questionnaire. Participants were classified as never married, married, divorced and widowed. Discriminant analysis revealed that vegetable consumption, followed by red meat, potatoes, poultry, and soft drinks were the factors with the higher discriminating ability among the food groups studied. In particular, dietary patterns of never married participants were characterized by the consumption of potatoes and red meat, those of married participants by nuts, legumes and fish, those of divorced participants by fruits, cereals and soft drinks, whereas those of widowed participants by dairy, vegetables, sweets and poultry. In addition, never married and divorced participants reported eating fast-foods more frequently and drink less alcohol compared to married or widowed participants. After controlling for potential confounders (i.e., age, gender, physical activity, anxiety score and smoking habits), the reported marital status of the participants was associated only with body mass index and total serum cholesterol levels. When the analysis was repeated after taking into account the information on dietary habits by creating four "new" dietary-adjusted marital status groups, no significant association was revealed between marital status and body mass index and blood cholesterol levels.

    Full Text Available Louis Montrose's "Professing the Renaissance: the Poetics and Politics of Culture" renewed concern with the historical, social and political conditions of literary productions (1989. He suggested a platform through which autonomous aesthetics and academic issues to be understood as inextricably linked to other discourses. While autobiography is considered as a "writing back," I argue here that it is rather a strategic transitional act that connects the past with the present and remaps the future. Though a very personal opening, autobiography is seen as a documentation of public events from a personal perspective. Academic autobiographies like Arab American history professor Leila Ahmad's A Border Passage from Cairo to America; A Woman’s Journey (2012 and African American theology professor Amina Wadud’s Inside the Gender Jihad (2008 are two examples of the production of interwoven private and public histories. The personal opening in such narratives is an autonomous act that initiates cross-disciplinary dialogues that trigger empowerment and proposes future changes. In that sense, these autobiographies are far from being mere stories of the past. Conversely, they are tools of rereading one's contributions and thus repositioning the poetics and politics of culture as testimonial narratives. Employing post-colonial, Islamic feminism and new historicism, the aim of this study is to critically read the above academic/personal two autobiographies as examples of the private/ public negotiations of culture. It also aims to explore the dialogue between the literary, historical and social elements as they remap the future of women in Muslim societies and the diaspora.

    The pandemic of obesity is a global public health concern. Most studies on obesity are skewed toward high-income and urban settings and few covers low-income populations. This study focused on the prevalence of overweight and obesity and their correlations with blood lipids/metabolites/enzymes (bio-indicators) in a rural community typical of low-income in remote western China. This study was performed in a Muslim ethnic Uyghur rural community in Kashi Prefecture of Xinjiang, about 4,407 km (2,739 miles) away from Beijing. Body mass index (BMI) and major blood bio-indicators (25 total items) were measured and demographic information was collected from 1,733 eligible healthy women aged 21 to 71 yrs, of whom 1,452 had complete data for analysis. More than 92% of the women lived on US$1.00/day or less. According to the Chinese criteria, overweight and obesity were defined as BMI at 24 to public health policies in Uyghur communities. To prevent diabetes and cardiovascular diseases in low-income settings, we therefore propose a cost-effective, two-step strategy first to screen for obesity and then to screen persons with obesity for diabetes and cardiovascular diseases.

    Falls are a serious health problem for aged people, causing social and economic burden. Despite being an important determinant of balance, the positioning of the center of mass (COM) has not been evaluated as a risk factor for falls. This study examined the association between the percentage height of COM (%COM) and the risk of falls in the elderly. Healthy women aged 60 years and older were consecutively selected in a case-control study. Forty-eight individuals classified as "fallers" (having suffered two or more falls in the previous year) were the cases while 48 age and weight-matched women with one fall or no falls in the previous year were the controls ("non-fallers"). Body composition and bone mineral density (BMD) by DXA, 30-second chair stand test, abdominal circumference, Berg's balance scale and %COM using the reaction board method were evaluated in all participants. Body composition parameters were not significantly different between groups. Spine and hip BMD tended to be lower in the fallers, but the difference was significant only at the femoral neck (0.80±0.10g/cm(2) versus 0.87±0.76g/cm(2); pfalls. Further work is needed in order to determine the value of board reaction measurements in a clinical setting to identify patients at high risk. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available The aim of this study was to assess whether the gender-specific pattern of fat mass (FM distribution is related to gender differences in cardiometabolic risk factors. 207 healthy middle-aged Japanese were included in the study. We measured FM in the total body, trunk, and lower-body with dual-energy X-ray absorptiometry (DXA. The percentage of trunk FM (TFM and lower-body FM (LFM is noted as %TFM and %LFM, respectively. Other measurements included glucose and insulin during oral glucose tolerance test (OGTT, leptin, adiponectin, plasminogen activator inhibitor-1 (PAI-1, tumor necrosis factor-α (TNF-α, C-reactive protein (CRP, and systemic oxidative stress marker. Arterial properties were indicated by cardio-ankle vascular index (CAVI and intima-media thickness (IMT of the common carotid artery. The results showed that %TFM is higher whereas %LFM is lower in men than in women and men have a more atherogenic cardiometabolic profile. In both genders, %TFM (%LFM is related to an unfavorable (favorable cardiometabolic profile. In particular, the relation between %LFM and OGTT-derived insulin sensitivity index is stronger in women than in men. These findings suggested that in relatively healthy adults, android and gynoid pattern of FM distribution contributes to gender differences in cardiometabolic risk factors.

    To investigate factors affecting the low lean body mass (LBM) of young women, we focused on the increase in body weight until one year of age and current lifestyles. In 442 young women, the increase in body weight from birth until one year of age, breast-feeding method in infancy, current physique index and body composition, and physique and lifestyles were investigated using a questionnaire. Subjects with an LBM percentile of less than 33.3 (less than 36.8 kg) were classified as having a low LBM (n = 150), and those with a 33.3 or higher LBM percentile as the control (n = 293). Based on body weight changes from birth to days 3 and 7, the subjects were divided into a rapid weight gain group and two non-rapid weight gain groups (groups 1-3). To analyze factors involved in a low LBM, multivariate analysis using a logistic model was employed. The prevalence of a low LBM in the rapid weight gain group was 0.41 times higher than in the others. The prevalence of a low LBM with a low birth weight was 0.58 times higher, indicating that a low birth weight is likely to result in a low LBM. Regarding the lifestyles, the prevalence of a low LBM in subjects with a current breakfasting habit was 0.60 times higher than in those without one. These findings suggest that the thinness of young women characterized by a low LBM is associated with the increase in body weight until one year of age and current lifestyles.

    To evaluate the effectiveness of a population-based, statewide public health intervention designed to improve women's awareness and knowledge of the link between alcohol and cancer. Cross-sectional tracking surveys conducted pre-intervention and post-intervention (waves I and III of campaign). Western Australia. Cross-sectional samples of Western Australian women aged 25-54 years before the campaign (n=136) and immediately after wave I (n=206) and wave III (n=155) of the campaign. The 'Alcohol and Cancer' mass media campaign ran from May 2010 to May 2011 and consisted of three waves of paid television advertising with supporting print advertisements. Campaign awareness; knowledge of drinking guidelines and the link between alcohol and cancer; intentions towards drinking. Prompted recognition of the campaign increased from 67% following wave I to 81% following wave III (adjusted OR (adj OR)=2.31, 95% CI 1.33 to 4.00, p=0.003). Improvements in women's knowledge that drinking alcohol on a regular basis increases cancer risk were found following wave I (adj OR=2.60, 95% CI 1.57 to 4.30, pawareness of links between alcohol and cancer, and knowledge of drinking guidelines. However, a single campaign may be insufficient to measurably curb drinking behaviour in a culture where pro-alcohol social norms and product marketing are pervasive.

    The residential neighbourhood fast-food environment has the potential to lead to increased levels of obesity by providing opportunities for residents to consume energy-dense products. This longitudinal study aimed to examine whether change in body mass index (BMI) differed dependent on major chain fast-food outlet availability among women residing in disadvantaged neighbourhoods. Eighty disadvantaged neighbourhoods in Victoria, Australia. Sample of 882 women aged 18-46 years at baseline (wave I: 2007/2008) who remained at the same residential location at all three waves (wave II: 2010/2011; wave III: 2012/2013) of the Resilience for Eating and Activity Despite Inequality study. BMI based on self-reported height and weight at each wave. There was no evidence of an interaction between time and the number of major chain fast-food outlets within 2 (p=0.88), 3 (p=0.66) or 5 km (p=0.24) in the multilevel models of BMI. Furthermore, there was no evidence of an interaction between time and change in availability at any distance and BMI. Change in BMI was not found to differ by residential major chain fast-food outlet availability among Victorian women residing in disadvantaged neighbourhoods. It may be that exposure to fast-food outlets around other locations regularly visited influence change in BMI. Future research needs to consider what environments are the key sources for accessing and consuming fast food and how these relate to BMI and obesity risk. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Obesity, hypertension, and hypertriglyceridemia are important risk factors for type 2 diabetes (T2D). We wanted to assess the risk associated with these three factors alone and in combination, and the relative importance of these and several other risk factors (eg, nonfasting glucose) as predictors of T2D. Risk factors in a Norwegian population (n = 109,796) aged 40-45 years were measured in health studies in 1995-1999. Blood glucose-lowering drugs dispensed in 2004-2009 were used to estimate the incidence of T2D. Groups based on combinations of body mass index (BMI), diastolic blood pressure, and triglycerides were defined by using the 50% and 90% quantiles for each variable for men and women. The relative importance of BMI, triglycerides, total cholesterol, high-density lipoprotein cholesterol, glucose, blood pressure, and year of birth for predicting T2D was assessed using deviance from univariate and multivariate logistic regression models. Height, weight, and blood pressure were measured. All biomarkers were measured in nonfasting blood samples. In the various groups of BMI, triglycerides, and diastolic blood pressure, the incidence of T2D ranged from 0.5% to 19.7% in men and from 0.15% to 21.8% in women. BMI was the strongest predictor of incident T2D, followed by triglyceride levels in women and glucose levels in men. The inclusion of risk factors other than BMI, glucose, triglycerides, and blood pressure in multivariate models only marginally improved the prediction. BMI was the strongest predictor of type 2 diabetes. At defined levels of BMI, the incidence of T2D varied substantially with triglyceride levels and blood pressure. Thus, controlling triglycerides and blood pressure in middle-aged individuals should be targeted to prevent later onset of T2D.

    Nine hundred eight women aged 40-88 years living in a non-Cd-polluted area in Japan were analyzed for urinary cadmium (Cd) N-acetyl-β-D-glucosaminidase (NAG) activity, β 2 -microglobuli (B2MG) concentration, and for the stiffness index (STIFF) of calcaneal bone using an ultras
