    Full Text Available BACKGROUND: We conducted quantitative and qualitative studies to explore barriers and motivating factors to VMMC for HIV prevention, and to assess utilization of existing VMMC communication channels. METHODS AND FINDINGS: A population-based survey was conducted with 2350 respondents aged 15-49. Analysis consisted of descriptive statistics and bivariate analysis between circumcision and selected demographics. Logistic regression was used to determine predictors of male circumcision uptake compared to intention to circumcise. Focus group discussions (FGDs were held with men purposively selected to represent a range of ethnicities. 68% and 53% of female/male respondents, respectively, had heard about VMMC for HIV prevention, mostly through the radio (71%. Among male respondents, 11.3% reported being circumcised and 49% reported willingness to undergo VMMC. Factors which men reported motivated them to undergo VMMC included HIV/STI prevention (44%, improved hygiene (26%, enhanced sexual performance (6% and cervical cancer prevention for partner (6%. Factors that deterred men from undergoing VMMC included fear of pain (40%, not believing that they were at risk of HIV (18%, lack of partner support (6%. Additionally, there were differences in motivators and barriers by age. FGDs suggested additional barriers including fear of HIV testing, partner refusal, reluctance to abstain from sex and myths and misconceptions. CONCLUSIONS: VMMC demand-creation messages need to be specifically tailored for different ages and should emphasize non-HIV prevention benefits, such as improved hygiene and sexual appeal, and need to address men's fear of pain. Promoting VMMC among women is crucial as they appear to have considerable influence over men's decision to get circumcised.

    Men's preventive health and wellness is largely neglected in rural Nicaragua, where a machismo culture prevents men from seeking health care. To address this issue, a men's educational group appointment model was initiated at a rural health post to increase awareness about hypertension, and to train community health leaders to measure blood pressure. Men's hypertension workshops were conducted with patient knowledge pretesting, didactic teaching, and posttesting. Pretesting and posttesting performances were recorded, blood pressures were screened, and community leaders were trained to perform sphygmomanometry. An increase in hypertension-related knowledge was observed after every workshop and community health leaders demonstrated proficiency in sphygmomanometry. In addition, several at-risk patients were identified and follow-up care arranged. Men's educational group appointments, shown to be effective in the United States in increasing patient knowledge and satisfaction, appear to function similarly in a resource-constrained environment and may be an effective mechanism for reaching underserved men in Nicaragua.

    Full Text Available Abstract Background Voluntary HIV counselling and testing (VCT is one of the key strategies in the HIV/AIDS prevention and control programmes in Ethiopia. However, utilization of this service among adults is very low. The aim of the present study was to investigate factors associated with VCT utilization among adult men since men are less likely than women to be offered and accept routine HIV testing. Methods The study utilized data from the Ethiopian Demographic Health Survey (EDHS 2005, which is a cross-sectional survey conducted on a nationally representative sample. Using cluster sampling, 6,778 men aged 15–59 years were selected from all the eleven administrative regions in Ethiopia. Logistic regression was used to analyze potential factors associated with VCT utilization. Results Overall, 21.9% of urban men and 2.6% of rural men had ever tested for HIV through VCT and most of them had learned their HIV test result. Having no stigmatizing attitudes toward people living with HIV/AIDS was found to be strongly and positively associated with VCT utilization in both urban and rural strata. In rural areas HIV test rates were higher among younger men (aged ≤44 years and those of higher socio-economic position (SEP. Among urban men, risky sexual behaviour was positively associated with VCT utilization whereas being Muslim was found to be inversely associated with utilization of VCT. Area of residence as well as SEP strongly affected men’s level of stigmatizing attitudes toward people living with HIV/AIDS. Conclusions VCT utilization among men in Ethiopia was low and affected by HIV/AIDS-related stigma and residence. In order to increase VCT acceptability, HIV/AIDS prevention and control programs in the country should focus on reducing HIV/AIDS-related stigma. Targeting rural men with low SEP should be given first priority when designing, expanding, and implementing VCT services in the country.

    The willingness of male-male dyads to use couples voluntary HIV counseling and testing (CVCT) has not been previously investigated globally among men who have sex with men (MSM). Using online advertisements, data were collected from 3245 MSM in seven countries who were ≥ 18 years of age and had ≥1 male sex partner in the previous 12 months. The analysis examined associations between individual characteristics and willingness to utilize CVCT. The willingness to utilize CVCT was compellingly high, ranging from 79% in Australia and UK to 90% in Brazil. Older MSM and those who reported not knowing their sero-status reported lower odds of willingness to use CVCT. The relationship between being in a relationship and willingness to use CVCT varied across countries, perhaps reflecting varied local understandings of the nature and content of CVCT. Further work is required to examine willingness to use CVCT among a more heterogeneous population of MSM, and to examine how CVCT services are locally perceived in order to provide information vital for the development of locally appropriate messages to promote CVCT for MSM.

    Full Text Available In 2012, South Africa set a goal of circumcising 4.3 million men ages 15-49 by 2016. By the end of March 2014, 1.9 million men had received voluntary medical male circumcision (VMMC. In an effort to accelerate progress, South Africa undertook a modeling exercise to determine whether circumcising specific client age groups or geographic locations would be particularly impactful or cost-effective. Results will inform South Africa's efforts to develop a national strategy and operational plan for VMMC.The study team populated the Decision Makers' Program Planning Tool, Version 2.0 (DMPPT 2.0 with HIV incidence projections from the Spectrum/AIDS Impact Module (AIM, as well as national and provincial population and HIV prevalence estimates. We derived baseline circumcision rates from the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey. The model showed that circumcising men ages 20-34 offers the most immediate impact on HIV incidence and requires the fewest circumcisions per HIV infection averted. The greatest impact over a 15-year period is achieved by circumcising men ages 15-24. When the model assumes a unit cost increase with client age, men ages 15-29 emerge as the most cost-effective group. When we assume a constant cost for all ages, the most cost-effective age range is 15-34 years. Geographically, the program is cost saving in all provinces; differences in the VMMC program's cost-effectiveness across provinces were obscured by uncertainty in HIV incidence projections.The VMMC program's impact and cost-effectiveness vary by age-targeting strategy. A strategy focusing on men ages 15-34 will maximize program benefits. However, because clients older than 25 access VMMC services at low rates, South Africa could consider promoting demand among men ages 25-34, without denying services to those in other age groups. Uncertainty in the provincial estimates makes them insufficient to support geographic targeting.

    Voluntary and stimulated contractions are commonly used in sports training and rehabilitation, and it is well known that both these kinds of contractions generate central fatigue. However, to date, there is a lack of research on the comparison of the mechanisms by which these 2 exercises induce central disturbances. Central fatigue can be characterized by central activation failure during maximal voluntary contraction (MVC). Superimposition of an electrical stimulation onto MVC has been used to detect central activation failure. Completeness of activation has been quantified by the central activation ratio (CAR) = MVC/(MVC + stimulated force). The aim was not only to evaluate the CAR immediately after fatiguing voluntary (VOL) and stimulated (STIM) contractions but also to compare recovery duration over different time periods (prefatigue: PRE condition; immediate postfatigue: POST condition; after a 5-minute recovery: POST 5 condition; after a 30-minute recovery: POST 30 condition) (n = 18). Results showed that in the POST condition, the CAR is more affected for the VOL contractions than for the STIM contractions (p contractions only in the POST 5 condition (p contractions, whereas it was complete for the VOL contractions (p contractions alter the CAR more than the STIM contractions immediately after their completion. However, the effects of the STIM contractions on the CAR are delayed and prolonged.

    This article presents an investigation into capacity building, at the community level, in Aboriginal and Torres Strait Islander Men's Groups and Sheds. As safe men's spaces, Men's Groups and Sheds represent an ever-growing social, and health and well-being community service across Australia. The study is qualitative and employs 'yarning circles' (focus groups), semi-structured interviews and observations to gather data from 15 Groups/Sheds involving 45 men from urban, regional and remote communities. We found that capacity building is primarily about securing relationships between Group Leaders/Shed Co-ordinators and Government services. Capacity building establishes links to services such as Centrelink, Medicare, Department of Housing, Probation and Control, and positive outcomes such as Indigenous men securing housing and Centrelink payments. Capacity building results in better health outcomes and, educates and empowers men to improve their social, cultural, emotional and economic well-being. It helps men to better connect with family and community. The current research paves the way for countries worldwide to explore the conceptual and empirical approach of capacity building applicable to other Indigenous [and non-Indigenous] Men's Groups/Sheds. We recommend feasibilities studies, on approaches to capacity building in Indigenous Groups/Sheds, be carried out within urban, regional and remote regions across the country. © The Author (2014).

    Main partnerships represent one context in which HIV transmission may occur that has been insufficiently addressed to date for gay and bisexual men, but few studies have focused on the acceptability of couples-based voluntary HIV counseling and testing (CVCT) for male couples in the U.S. Our aim in this study was to explore the acceptability of CVCT among a national U.S. sample of 1,532 gay and bisexual men surveyed online using a sexual networking site. We examined the role of demographic (i.e., geographic region, age, relationship status, sexual orientation, race/ethnicity) and HIV risk (i.e., substance use, number of sexual partners, unprotected anal intercourse, sexual role identity, and sexual compulsivity) factors that may be associated with CVCT among the full sample and among partnered men separately. We found that single men expressed higher interest in CVCT than partnered men and that greater age was more strongly associated with lower interest in CVCT for partnered men than for single men. The intersection of sexual orientation and race/ethnicity was also significantly associated with CVCT interest, with a higher proportion of Black bisexual men being interested than White bisexual men. These findings suggest that the uptake of CVCT may be less impacted by HIV risk factors than by demographic factors and that young gay and bisexual men of color-for whom rates of HIV continue to rise-may be the group with the highest levels of interest in CVCT.

    Full Text Available Background: The number of human immunodeficiency virus (HIV cases is high and is constantly increasing. Homosexual men as a transmission niche is not only significant in terms of numbers, but also in natural aspects of anal sex, tropism of HIV-1, and high-risk behavior. Voluntary Counseling and Testing (VCT is important for accelerating diagnosis and management plan; yet the uptake on high-risk population in Indonesia is low. A behavior-reasoning theory, Health Belief Model (HBM, attempts to explain whether or not individuals engage in certain health behavior. This study tries to assess participation rate of VCT, to portray HBM variables perception, and to depict significance of HBM variables towards VCT uptake or VCT intention. Methods: This study was conducted in October-November 2014 using cross-sectional design; 127 respondents were gathered according to Respondent Driven Snowball Sampling. This study used an internet-based questionnaire derived from Champion’s 1984 mammogram HBM questionnaire. Privacy and compensation were obtained. The Chi square test and logistic regression of HBM variables were done. Results: The VCT uptake was low (15.7%. Certain sexual experience and commitment were significant (Commitment to Men p=0.027, Oral Sex experience with men p=0.001, Anal Sex Experience with men p=0.038. Chi Square test revealed significance on Perceived Susceptibility, Perceived Benefit, and Cues to Action. Conclusions: Uptake of VCT is considerably low compared with total high risk population and other similar studies. Personal Susceptibility to HIV/AIDS is recommended to be emphasized; while VCT Benefit and Cues to Action in young homosexual men communities are better encouraged.

    Our goal was to assess whether men in the following three groups differ in their ability to recognize and judge the severity of diverse forms of aggressive behavior: (a) men who reported being physically aggressive toward their spouses and who were entering treatment for domestic violence; (b) men who, after participating in a treatment program, were no longer physically violent; and (c) men who reported never having been physically violent towards their spouses (NPV group-non-physically violent). All 81 men in the study reported being verbally aggressive toward their spouses. Men who had been in treatment for spousal abuse and who had not been physically violent toward their spouses since finishing the program were better able than the other two groups to recognize emotionally abusive behaviors.

    To describe sociodemographics, sexual risk behavior, and estimate HIV and sexually transmitted infection (STI) prevalence among men who have sex with men (MSM) in Mumbai, India. Eight hundred thirty-one MSM attending voluntary counseling and testing (VCT) services at the Humsafar Trust, answered a behavioral questionnaire and consented for Venereal Disease Research Laboratory and HIV testing from January 2003 through December 2004. Multivariate logistic regression was performed for sociodemographics, sexual risk behavior, and STIs with HIV result as an outcome. HIV prevalence among MSM was 12.5%. MSM who were illiterate [adjusted odds ratio (AOR) 2.28; 95% confidence interval (CI): 1.08 to 4.84], married (AOR 2.70; 95% CI: 1,56 to 4.76), preferred male partners (AOR 4.68; 95% CI: 1.90 to 11.51), had partners of both genders (AOR 2.73; 95% CI: 1.03 to 7.23), presented with an STI (AOR 3.31; 95% CI: 1.96 to 5.61); or presented with a reactive venereal disease research laboratory test (AOR 4.92; 95% CI: 2.55 to 9.53) at their VCT visit were more likely to be HIV infected. MSM accessing VCT services in Mumbai have a high risk of STI and HIV acquisition. Culturally appropriate interventions that focus on sexual risk behavior and promote condom use among MSM, particularly the bridge population of bisexual men, are needed to slow the urban Indian AIDS epidemic.

Understanding and implementation of these issues is necessary......Osteoporotic fractures in men are an increasing public health problem. Male osteoporosis is often a low-prioritized issue, however. To examine men's experiences with osteoporosis and how they handle osteoporosis in their everyday lives, the authors collected data from four focus groups with a total...... of 16 men aged 51 to 82 years diagnosed with osteoporosis. Critical psychology was used as a theoretical framework for the data analysis, which aimed to elicit information about the men's daily lives. The men handled osteoporosis in different ways using different strategies. The authors found patterns...

    Blood donation results in a substantial iron loss and subsequent mobilization from body stores. Chronic iron deficiency is a well-recognized complication of regular blood donation. The present study conducted to compare the level of serum ferritin, serum iron, total iron binding capacity (TIBC) and percentage transferrin saturation in different ABO and Rhesus type blood groups among the voluntary blood donors of Bangladesh. The present prospective study included 100 healthy voluntary donors attending at Department of Blood Transfusion, Dhaka Medical College, Dhaka between the periods of July 2013 to Jun 2014. From each donor 10mL venous blood sample was taken and divided into heparinized and non-heparinized tubes for determination of hemoglobin (Hb), hematocrit (Hct), serum iron (SI), total iron binding capacity (TIBC) and serum ferritin by standard laboratory methods. Percentage of transferrin saturation (TS) calculated from serum iron and TIBC. Data were analyzed with SPSS (version 16) software and comparisons between groups were made using student's t-test and one way ANOVA. In the present study mean±SD of age of the respondents was 27.2±6.5 years with a range of 18 to 49 years and 81.0% were male and 19.0% were female. Among the donors 18.0% had blood group A, 35.0% had blood group B, 14.0% had blood group AB and 33.0% had blood group O. Among the donors 91.0% had rhesus positive and 9.0% had rhesus negative. Donors with blood group O had lowest haemoglobin, serum iron and transferring saturation levels. Donors with blood group A had highest TIBC level. Donors with blood group B had lowest serum ferritin level. An independent samples 't' test showed statistically significant difference in serum ferritin and percentage transferrin saturation between blood group AB and blood group O and in percentage transferrin saturation between blood group B and blood group O. One way ANOVA showed that there is no significant difference in haemoglobin, serum iron, serum

    Linear growth curve modeling was used to compare rates of change in functional status between three groups of older adults: Individuals holding voluntary lay leadership positions in a church, regular church attenders who were not leaders, and those not regularly attending church. Functional status was tracked longitudinally over a 4-year period in a national sample of 1,152 Black and White older adults whose religious backgrounds were either Christian or unaffiliated. Leaders had significantly slower trajectories of increase in both the number of physical impairments and the severity of those impairments. Although regular church attenders who were not leaders had lower mean levels of impairment on both measures, compared with those not regularly attending church, the two groups of non-leaders did not differ from one another in their rates of impairment increase. Leadership roles may contribute to longer maintenance of physical ability in late life, and opportunities for voluntary leadership may help account for some of the health benefits of religious participation.

    Objective: To understand the human papilloma virus (HPV) infection status in men who have sex with men (MSM) recruited from gay bathhouses and HIV voluntary counseling and testing (VCT) clinics in Urumqi, Xinjiang Uygur autonomous region, and identify the associated risk factors. Methods: A total of 200 MSM aged ≥18 years were recruited by using the " snowballing" sampling method from gay bathhouses and VCT clinics in Urumqi during March-May, 2016. The MSM recruited completed questionnaires after filling in the informed consent form. The information about their demographic characteristics and sexual behaviors were collected, and anal swabs were collected from them for HPV genotyping. Results: The overall HPV infection rate was 54.0%. The HPV infection rate was 66.7%(74/111) in MSM from gay bathhouses and 38.2%(34/89) in MSM from VCT clinics and the high risk type HPV infection rate was 39.6% (44/111) in MSM from gay bathhouses and 14.6% (13/89) in MSM from VCT clinics, the differences were significant (χ(2)=16.112, Pgay bathhouse (OR=3.732, 95% CI: 1.950-7.141) and anal sexual behavior (OR=2.555, 95%CI: 1.329-4.912). Conclusion: The prevalence of HPV in MSM from gay bathhouses was higher than that in MSM from VCT clinics, indicating that close attention should be paid to the behavior intervention in MSM.

    To understand the human immunodeficiency virus (HIV) infection status and syphilis prevalence among men who have sex with men (MSM) receiving voluntary counseling and testing appointed through a web-based registering system and related factors. The MSM receiving web appointed HIV counseling and testing from 2011 to 2012 in Guangzhou were recruited and a questionnaire survey was conduct among them to obtain the information about their demographic characteristics and sexual behavior. Binary and multivariate logistic regression model were used to identify the factors associated with HIV infection or syphilis prevalence. A total of 4,904 MSM were enrolled in the study, the average age of the MSM was (28.77±7.24) years, and 70.3% of them had high education level; the unmarried MSM accounted for 72.7%. The HIV infection rate and syphilis prevalence were 8.7% and 4.4% respectively. The co-infection rate of HIV and Treponema pallidum was 1.2% (59/4 904). About one in three MSM did not use condom at latest homosexual behavior, 43.5% did not use condoms at each homosexual behavior in the past three months. Lower education level, occupation (worker or farmer), non-consistent condom use at each sex with men in the past three months, receiving HIV test or not and Treponema pallidum infection were associated with HIV infection. Age≥40 years, lower education level, multi male sex partners in the past three months and HIV infection were associated with Treponema pallidum infection. MSM receiving web appointed HIV counseling and testing had high prevalence of risk behaviors and high HIV infection rate, but had low previous HIV testing rate. It is necessary to strengthen the promotion of HIV test through web based appointment and conduct target behavior intervention in older MSM with lower education level.

    Preventing involuntary conscription and voluntary recruitment of youth into armed groups are global human rights priorities. Pathways for self-reported voluntary recruitment and the impact of voluntary recruitment on mental health have received limited attention. The objective of this study was to identify risk factors for voluntarily joining armed groups, as well as the association of conscription status and mental health. In Nepal, interviews were conducted with 258 former child soldiers who participated in a communist (Maoist) revolution. Eighty percent of child soldiers joined 'voluntarily'. Girls were 2.07 times as likely to join voluntarily (95% CI, 1.03-4.16, p=0.04). Among girls, 51% reported joining voluntarily because of personal connections to people who were members of the armed group, compared to 22% of boys. Other reasons included escaping difficult life situations (36%), inability to achieve other goals in life (28%), and an appealing philosophy of the armed group (32%). Poor economic conditions were more frequently endorsed among boys (22%) than girls (10%). Voluntary conscription was associated with decreased risk for PTSD among boys but not for girls. Interventions to prevent voluntary association with armed groups could benefit from attending to difficulties in daily life, identifying non-violent paths to achieve life goals, and challenging the political philosophy of armed groups. Among boys, addressing economic risk factors may prevent recruitment, and prevention efforts for girls will need to address personal connections to armed groups, as it has important implications for preventing recruitment through new methods, such as social media.

    HBsAg positive subjects belonging to high risk groups and voluntary blood donors were analysed for prevalence of HBsAg among various groups of subjects for ascertaining the carrier status among the voluntary blood donors, HBsAg subtype distribution, and association of HBsAg with blood groups and caste or religion. The prevalence of HBsAg varied from 2.02 per cent in voluntary blood donors to 58.38 per cent in patients of acute viral hepatitis. 70.5 per cent subjects had subtype 'ay' while 23.9 per cent of the subjects had subtype 'ad'. We also found compound 'ady' subtype in 5.6 per cent of our subjects. HBsAg/adr, a subtype not usually prevalent in India, was found in 30 of the 90 'ad' sera. Co-occurrence of HBsAg and anti-HBs was noted in 9 subjects. Homotypic anti-HBs was found to occur together mainly in voluntary blood donors, while heterotypic anti-HBs was found to occur together mainly multi-transfused patients. There was no significant correlation between HBsAg and blood group antigens and a relatively higher incidence of HBsAg among the Jain community was observed.

    We evaluated the direct relation between group sex and prevalent sexually transmitted infections (STI) in a cross-sectional study of men who have sex with men (MSM) presenting at an urban STI clinic in the Midwestern US. Among 231 men who enrolled and reported that they have sex with men, we collected behavioral data using a combination of interviewer and self-administered surveys and extracted STI data from electronic health records. We used modified Poisson regression to examine the unadjusted and adjusted associations between group sex participation and prevalent STI. One-quarter of participants (n = 58) reported group sex participation in the last 3 months. Eighteen percent of participants (n = 42) had gonorrhea and 19 % (n = 45) had chlamydial infection. Men who reported recent group sex were more likely to be HIV-positive, to report recent drug use, and to report unprotected receptive anal intercourse in the past 3 months. After adjustment for age, race, and recent drug use, recent participation in group sex was associated with prevalent gonorrhea infection (prevalence ratio [PR] = 2.11, 95 % confidence interval [CI] = [1.13, 3.95]) but not chlamydia infection (PR = 1.03, 95 % CI = [0.58, 1.84]). We performed a sensitivity analysis in which we also adjusted for unprotected receptive anal intercourse and the results were not substantively changed. In summary, participation in group sex in the past 3 months was associated with a more than twofold increased prevalence of gonorrhea, but not with chlamydia. These findings support group sex participation as a potential contributor to increased STI prevalence.

    Despite substantial growth in the service industry and emerging work on turnover consequences, little research examines how unit-level turnover rates affect essential customer-related outcomes. The authors propose an operational disruption framework to explain why voluntary turnover impairs customers' service quality perceptions. On the basis of a sample of 75 work units and data from 5,631 employee surveys, 59,602 customer surveys, and organizational records, results indicate that unit-level voluntary turnover rates are negatively related to service quality perceptions. The authors also examine potential boundary conditions related to the disruption framework. Of 3 moderators studied (group cohesiveness, group size, and newcomer concentration), results show that turnover's negative effects on service quality are more pronounced in larger units and in those with a greater concentration of newcomers.

  7. The Economic and Epidemiological Impact of Focusing Voluntary Medical Male Circumcision for HIV Prevention on Specific Age Groups and Regions in Tanzania

    Science.gov (United States)

    2016-01-01

    Background Since its launch in 2010, the Tanzania National Voluntary Medical Male Circumcision (VMMC) Program has focused efforts on males ages 10–34 in 11 priority regions. Implementers have noted that over 70% of VMMC clients are between the ages of 10 and 19, raising questions about whether additional efforts would be required to recruit men age 20 and above. This analysis uses mathematical modeling to examine the economic and epidemiological consequences of scaling up VMMC among specific age groups and priority regions in Tanzania. Methods and Findings Analyses were conducted using the Decision Makers’ Program Planning Tool Version 2.0 (DMPPT 2.0), a compartmental model implemented in Microsoft Excel 2010. The model was populated with population, mortality, and HIV incidence and prevalence projections from external sources, including outputs from Spectrum/AIDS Impact Module (AIM). A separate DMPPT 2.0 model was created for each of the 11 priority regions. Tanzania can achieve the most immediate impact on HIV incidence by circumcising males ages 20–34. This strategy would also require the fewest VMMCs for each HIV infection averted. Circumcising men ages 10–24 will have the greatest impact on HIV incidence over a 15-year period. The most cost-effective approach (lowest cost per HIV infection averted) targets men ages 15–34. The model shows the VMMC program is cost saving in all 11 priority regions. VMMC program cost-effectiveness varies across regions due to differences in projected HIV incidence, with the most cost-effective programs in Njombe and Iringa. Conclusions The DMPPT 2.0 results reinforce Tanzania’s current VMMC strategy, providing newfound confidence in investing in circumcising adolescents. Tanzanian policy makers and program implementers will continue to focus scale-up of VMMC on men ages 10–34 years, seeking to maximize program impact and cost-effectiveness while acknowledging trends in demand among the younger and older age groups

    Assessing predictors of intention to circumcise can help to identify effective strategies for increasing uptake of voluntary medical male circumcision (VMMC). Grounded in the theory of reasoned action (TRA), the current study of uncircumcised males ages 13-29 in Swaziland (N = 1,257) employed multivariate logistic regression to determine predictors of VMMC intention. The strongest predictors were strongly disagreeing/disagreeing that sex was more painful for a circumcised man (odds ratio [OR] = 4.37; p = theory to explore young men's intention to circumcise and can help inform interventions aimed at increasing uptake of VMMC.

    Identifying subjects at high risk of weight gain according to consumption of food groups is important for individualizing nutritional education, but prospective studies of this issue have been few. We determined whether intake of specific food groups could predict future weight gain. We evaluated data from health checkups on 1236 Japanese men aged 28 to 87 years in 2005 and 2006. Dietary intake was assessed by a 24-h dietary recall at baseline. Weight change was measured after 1 year. Weight increased in 44.7% (n = 553) of participants. Multivariate regression analysis involving many food groups showed a significant association between sugar intake and weight gain after adjustment for age, body mass index (BMI), total energy intake, alcohol, smoking and regular physical exercise (β = 0.22, P = 0.04). The effect of intake of 'fats and oils' was significant when adjusted for age and BMI, however, it became insignificant after adjustment for age, BMI and total energy intake. Intake of sugar, which was evaluated as a food group, was predictive of subsequent weight gain among Japanese men, even after adjustment for many confounders. This corroborates the evidence so far concerning the links between sugar intake and weight gain. Further long-term research is required to give robust recommendation to the public.

    Full Text Available Several studies have shown that voluntary male medical circumcision (VMMC reduces the incidence of the Type-1 human immunodeficiency virus (HIV in heterosexual men by up to 60%. However, there is an increased risk of transmission of STIs, including HIV, in the immediate post-operative period after receiving VMMC. This study is to understand sexual practices of couples in the post-operative period in a Coloured population in the Western Cape Province of South Africa.Coloured Males who had undergone VMMC in the previous six months in the Cape Town area and their partners participated in eight single-gender focus group discussions. The groups explored why the men decided to undergo VMMC, what kind of counselling they received, and how they experienced the 6-week post-operative period, including sexually.The primary motivation to VMMC uptake included religious injunction and hygiene reasons and protection against sexually transmitted infections not necessarily HIV. There was some exploration of alternative sexual practices. During the period immediately post operation the respondents spoke of pain and fear of any sexual arousal, but towards the end of the six week period, sexual desire returned. Both men and women felt that sex was important to maintain the relationship. Gaps were identified in the pre- and post-MC procedure counselling.There is a real risk that men in this population may begin sex before complete healing has occurred. VMMC counselling to encourage men to stay sexually safe in the wound-healing period, needs to take into account the real-life factors of the circumcised men. It is essential from a public health, and gender perspective that effective counselling strategies for the VMMC post-operative period, and the longer term, are developed and tested.

    Full Text Available We describe the HIV risk perception, sexual behavior, and HIV prevalence among 423 men-who-have-sex-with-men (MSM clients who received voluntary counseling and testing (VCT services at a community-based center in Kuala Lumpur, Malaysia. The mean age was 29 years old. One hundred one (23.9% clients rated themselves as low risk, 118 (27.9% as medium risk, 36 (8.5% as high risk, and 168 (39.7% were unsure of their risk. Twenty-four (9.4% clients tested HIV positive (4 (4% low risk, 9 (7.6% medium risk, 11 (30.6% high risk, and 13 (7.7% unsure risk. We found a positive correlation between risk perception and HIV infection in this study. Clients with high HIV risk perception have 17x the odds of testing HIV positive compared to low risk clients. High HIV risk perception was significantly associated with multiple sex partners, multiple types of sex partners, alcohol use before intercourse, unprotected sex beyond 6 months, and inconsistent condom use during anal sex compared to low risk clients. There were no statistically significant differences between medium risk and unsure risk clients compared to low risk clients. Strategies should be targeted towards change in sexual practices among those who are perceived to be at high risk.

    Full Text Available BACKGROUND: Uptake of VMMC among adult men has been lower than desired in Nyanza, Kenya. Previous research has identified several barriers to uptake but qualitative exploration of barriers is limited and evidence-informed interventions have not been fully developed. This study was conducted in 2012 to 1 increase understanding of barriers to VMMC and 2 to inform VMMC rollout through the identification of evidence-informed interventions among adult men at high risk of HIV in Nyanza Province, Kenya. METHODS: Focus groups (n = 8 and interviews were conducted with circumcised (n = 8 and uncircumcised men (n = 14 from the two districts in Nyanza, Kenya. Additional interviews were conducted with female partners (n = 20, health providers (n = 12, community leaders (n = 12 and employers (n = 12. Interview and focus group guides included questions about individual, interpersonal and societal barriers to VMMC uptake and ways to overcome them. Inductive thematic coding and analysis were conducted through a standard iterative process. RESULTS: Two primary concerns with VMMC emerged 1 financial issues including missing work, losing income during the procedure and healing and family survival during the recovery period and 2 fear of pain during and after the procedure. Key interventions to address financial concerns included: a food or cash transfer, education on saving and employer-based benefits. Interventions to address concerns about pain included refining the content of demand creation and counseling messages about pain and improving the ways these messages are delivered. CONCLUSIONS: Men need accurate and detailed information on what to expect during and after VMMC regarding both pain and time away from work. This information should be incorporated into demand creation activities for men considering circumcision. Media content should frankly and correctly address these concerns. Study findings support scale up and/or further improvement of these ongoing

    Full Text Available In this paper, we explore client resistances in group music therapy with women and men in residential treatment for substance use disorders (SUDs. We describe how we have encountered resident resistances on women's and men's units within a gender-specific treatment facility and offer suggestions for pre-empting and addressing such resistances, offering both nonmusical and musical strategies and techniques. We emphasize a person-centered approach and an experience orientation, in which we view our primary responsibility as providing opportunities for the men and women to engage meaningfully with music, self, therapists, and other residents in order to identify problems and explore alternatives and personal resources.

  17. Hemochromatosis Patients as Voluntary Blood Donors

    Full Text Available The present study was designed to investigate hemochromatosis patients' suitability as blood donors as well as their perceptions and experience with the current public donation system. Participants were gathered from a list of current hemochromatosis patients (n=120 and members of the Canadian Hemochromatosis Society (n=1000. Of the 1120 surveys mailed out to these groups, 801 surveys were returned completed. The sample respondents had a mean age of 57.44 years (SD=12.73; range 19 to 87 years, and 57% were men. It was found that 20% (160 of the respondents have donated blood since their diagnosis; however, only 12% of the respondents indicated that they use voluntary blood donation as a means of maintaining their iron levels. Forty per cent of the respondents indicated that they had been refused from voluntary donation. Despite the fact that in May 2001 the Canadian Blood Services, in collaboration with the Canadian Hemochromatosis Society, began a promotion campaign to encourage hemochromatosis patients to become voluntary blood donors, the present study found that 15% of the respondents reported having been refused from the voluntary blood donation service due to the diagnosis of hemochromatosis. With respect to quality of life, it was found that individuals who donate blood were generally healthier with respect to physical functioning and bodily pain, however, these findings may indicate that hemochromatosis patients who are healthier are better able to donate at public blood banks, rather than that voluntary blood donation has an effect on the donors' physical functioning over phlebotomy clinic users. These study findings suggest that although there may be other medical factors limiting individuals from donating, hemochromatosis patients are interested in being voluntary blood donors and this potential resource is currently under-used.

    2009-09-01

    The aim of this study was to determine the applicability and reliability of a transcranial magnetic stimulation twitch interpolation technique for measuring voluntary activation of a lower limb muscle group. Cortical voluntary activation of the knee extensors was determined in nine healthy men on two separate visits by measuring superimposed twitch torques evoked by transcranial magnetic stimulation during isometric knee extensions of varying intensity. Superimposed twitch amplitude decreased linearly with increasing voluntary torque between 50 and 100% of mean maximal torque, allowing estimation of resting twitch amplitude and subsequent calculation of voluntary activation. There were no systematic differences for maximal voluntary activation within day (mean +/- s.d. 90.9 +/- 6.2 versus 90.7 +/- 5.9%; P = 0.98) or between days (90.8 +/- 6.0 versus 91.2 +/- 5.7%; P = 0.92). Systematic bias and random error components of the 95% limits of agreement were 0.23 and 9.3% within day versus 0.38 and 7.5% between days. Voluntary activation was also determined immediately after a 2 min maximal voluntary isometric contraction; in four of these subjects, voluntary activation was determined 30 min after the sustained contraction. Immediately after the sustained isometric contraction, maximal voluntary activation was reduced from 91.2 +/- 5.7 to 74.2 +/- 12.0% (P knee extensors.

    Full Text Available Background: Men who have sex with men and transgenders are an important risk group for sexually transmitted infections (STIs and human immunodeficiency virus (HIV. They have risky sexual behaviors but low risk perception. Objectives: To assess the sexual behavior, STIs, HIV, and identify factors associated with HIV in men who have sex with men (MSM and transgenders (TGs in Mumbai. Methods: Participants were enrolled from two clinics in Mumbai. They completed an interviewer-administered questionnaire and were evaluated for STIs and HIV infection. Results: A total of 150 participants, 122 MSM and 28 TGs were evaluated; 17% of MSM and 68% of the TGs were HIV infected. HIV infection in MSM was associated with serological positivity for HSV2 IgG [adjusted odds ratio (aOR, 95% confidence interval (CI: 9.0 (2.2-36.9], a positive Treponema pallidum hemagglutination assay (TPHA [aOR (95% CI: 6.0 (1.5-24.0], greater than five acts of receptive anal sex in the past six months [aOR (95% CI: 4.3 (1.2-15.0] and per category increase in age (18-24 yrs, 25-29 yrs, > 30 yrs [aOR (95% CI: 3.1 (1.3-7.1] in multivariate analysis. Consistent condom use during receptive anal sex in the past six months was low (27%. Many MSM were married (22% or had sex with females and may act as a ′bridge population′. HIV infection in TGs was associated with a positive TPHA [OR (95% CI: 9.8 (1.5-63.9] and HSV 2 IgG [OR (95% CI: 6.7 (1.1-40.4] in univariate analysis. Conclusion: Prior STIs were strongly associated with HIV infection in MSM and TGs. These groups should be the focus of intensive intervention programs aimed at STI screening and treatment, reduction of risky sexual behavior and promotion of HIV counseling and testing.

    The numbers of Asian American men are continually increasing, yet limited research exists on this understudied population. Addressing this lack of research is necessary to better inform how best to improve quality of care. This study examined health outcome differences across ethnically diverse groups of Asian American men in California, compared with non-Hispanic White men. Using data from the 2007, 2009, and 2011-2012 California Health Interview Survey, distributions of health status and health-related characteristics across ( n = 43,030) racial/ethnic groups of men (Chinese, Japanese, Korean, Filipino, Vietnamese, Other Asian Americans, and non-Hispanic Whites) were calculated. Compared with non-Hispanic Whites, odds of reporting fair or poor health were higher among Vietnamese, while odds of diabetes were higher among Korean, Filipino, and Other Asian Americans. Odds of high blood pressure were higher among Filipino and Vietnamese but lower among Other Asian Americans, while odds of disability were lower across all ethnic groups except Filipino and Vietnamese. This study's findings highlight the importance of understanding ethnic heterogeneity to develop culturally appropriate health interventions for Asian American men.

    Full Text Available BACKGROUND: Substance use during sex is associated with sexual risk behavior among men who have sex with men (MSM, and MSM continue to be the group at highest risk for incident HIV in the United States. The objective of this study is to test the efficacy of a group-based, cognitive-behavioral intervention to reduce risk behavior of substance-using MSM, compared to a randomized attention-control group and a nonrandomized standard HIV-testing group. METHODS AND FINDINGS: Participants (n = 1,686 were enrolled in Chicago, Los Angeles, New York City, and San Francisco and randomized to a cognitive-behavioral intervention or attention-control comparison. The nonrandomized group received standard HIV counseling and testing. Intervention group participants received six 2-h group sessions focused on reducing substance use and sexual risk behavior. Attention-control group participants received six 2-h group sessions of videos and discussion of MSM community issues unrelated to substance use, sexual risk, and HIV/AIDS. All three groups received HIV counseling and testing at baseline. The sample reported high-risk behavior during the past 3 mo prior to their baseline visit: 67% reported unprotected anal sex, and 77% reported substance use during their most recent anal sex encounter with a nonprimary partner. The three groups significantly (p0.05 from each other at 3-, 6-, and 12-mo follow-up. Outcomes for the 2-arm comparisons were not significantly different at 12-mo follow-up (e.g., unprotected anal sex, odds ratio = 1.14, confidence interval = 0.86-1.51, nor at earlier time points. Similar results were found for each outcome variable in both 2- and 3-arm comparisons. CONCLUSIONS: These results for reducing sexual risk behavior of substance-using MSM are consistent with results of intervention trials for other populations, which collectively suggest critical challenges for the field of HIV behavioral interventions. Several mechanisms may contribute to

    (1) To explore existing knowledge of, and attitudes, to group B meningococcal disease and serogroup B meningococcal (MenB) vaccine among parents of young children. (2) To seek views on their information needs. Cross-sectional qualitative study using individual and group interviews conducted in February and March 2015, prior to the introduction of MenB vaccine (Bexsero) into the UK childhood immunisation schedule. Community centres, mother and toddler groups, parents' homes and workplaces in London and Yorkshire. 60 parents of children under 2 years of age recruited via mother and baby groups and via an advert posted to a midwife-led Facebook group. Although recognising the severity of meningitis and septicaemia, parents' knowledge of group B meningococcal disease and MenB vaccine was poor. While nervous about fever, most said they would take their child for MenB vaccination despite its link to fever. Most parents had liquid paracetamol at home. Many were willing to administer it after MenB vaccination as a preventive measure, although some had concerns. There were mixed views on the acceptability of four vaccinations at the 12-month booster visit; some preferred one visit, while others favoured spreading the vaccines over two visits. Parents were clear on the information they required before attending the immunisation appointment. The successful implementation of the MenB vaccination programme depends on its acceptance by parents. In view of parents' recognition of the severity of meningitis and septicaemia, and successful introduction of other vaccines to prevent bacterial meningitis and septicaemia, the MenB vaccination programme is likely to be successful. However, the need for additional injections, the likelihood of post-immunisation fever and its management are issues about which parents will need information and reassurance from healthcare professionals. Public Health England has developed written information for parents, informed by these findings.

The study findings are drawn from participant observations conducted at 16 PCSGs in British Columbia, Canada and 54 individual interviews that focused on men's experiences of attending group meetings. Men's communication and interactions at PCSGs provide important insights for how men talk about and conceptualize health and illness. For example, biomedical language often predominated at group meetings, and men used numbers and measures to engage with risk discourses in linking prostate cancer markers to various treatment options and morbidity and mortality rates. Many groups afforded opportunities for men to interact with health care providers as a means to better understand the language and logic of prostate cancer management. The health literacy skills fostered at PCSGs along with specific group-informed strategies could be mobilized in the men's subsequent clinical consultations. Consumer discourses and strategies to contest power relations with health care professionals underpinned many men's search for prostate cancer information and their commitment to assisting other men. Key were patients' rights, and perhaps responsibility, to compare diverse health products and services in making decisions across the entire trajectory of their prostate cancer. Overall, the study findings reveal PCSGs as having the capacity to contest as well as align with medical expertise and services facilitating men's transition from patient to informed health care consumers. The processes through which this occurs may direct the design of older men's health promotion programs.

    The aim of this study was to analyze the technical-tactical performance profile of the serve for various age groups and categories of competition in men's volleyball. The sample comprised 13,262 serves performed by 986 players in 299 sets observed in various categories of competition (U-14, U-16, U-19, national senior, and international senior). An observational design was used. The variables studied were category of competition, type of execution, and serve performance. The results showed that for higher age groups (senior categories), there were significantly fewer jump serves and poorer serve performance, regardless of players' maturity and training development. The use of the jump serves increased the serve risk while attempting to hinder the organization of the opponent attack. This paper discusses the serve evolution and the implications on the training process at the different age groups in men's volleyball. © The Author(s) 2016.

  12. Recidivism is related to psychopathy (PCL-R) in a group of men convicted of homicide.

    It is well known that psychopaths are a group with high risk for criminality. Despite that, researchers and clinicians have not yet agreed on a general cause of psychopathy. However Raine [Raine, A. (2002). Biosocial studies of antisocial and violent behavior in children and adults: A review. Journal of Abnormal Child Psychology, 30, 311-326.] advocated a biosocial model of violent behaviour where the greatest risk for criminal behaviour occurred when both heredity and environmental risk factors (e.g., social class, childhood history) were present. In this follow-up study, 35 men convicted of homicide were assessed retrospectively for psychopathy according to the Psychopathy Checklist-Revised (PCL-R). Information on personal history, as well as from legal documents and records of offences committed by the subjects was also obtained. Fourteen of the 35 men were classified as psychopaths. Two men, both rated as psychopaths, had criminal parents. Twenty-seven of the men had a social relationship with their victim, and eleven out of these were rated as psychopaths. There was no difference in PCL-R scores between those who had a social relationship with their victim and those who did not. The psychopaths relapsed more frequently than the nonpsychopaths into criminality after their prison term. This result confirms previous research indicating that psychopathy is a risk factor for recidivism. It is, therefore, very important that psychopaths get the best possible treatment, aftercare, and supervision.

    The meningococcal groups C and Y and Haemophilus b (Hib) tetanus toxoid conjugate vaccine (HibMenCY-TT) contains Neisseria meningitidis serogroup C and Y capsular polysaccharide antigens, and Hib capsular polysaccharide [polyribosyl-ribitol-phosphate (PRP)]. The HibMenCY-TT vaccine is available in the USA for use as active immunization to prevent invasive disease caused by N. meningitidis serogroups C (MenC) and Y (MenY), and Hib in children 6 weeks-18 months of age. HibMenCY-TT is the first meningococcal vaccine available for use in the USA that can be administered to infants as young as 6 weeks of age. In a randomized, controlled, phase III clinical trial, the HibMenCY-TT vaccine, administered to infants at 2, 4, 6 and 12-15 months of age, was immunogenic against MenC and MenY, and met the prespecified criteria for immunogenicity. Anti-PRP antibodies, which have been shown to correlate with protection against Hib invasive disease, were also induced in the infants who received the HibMenCY-TT vaccine, with induced levels of this antibody noninferior to those occurring in the control group of infants who received a Hib tetanus toxoid conjugate vaccine at 2, 4, and 6 months and a single dose of Hib conjugated to N. meningitidis outer membrane protein at 12-15 months. In several randomized, controlled clinical trials, HibMenCY-TT was coadministered with vaccines that are routinely administered to infants and toddlers in the USA. These vaccines included: diphtheria and tetanus toxoids and acellular pertussis adsorbed, hepatitis B (recombinant) and inactivated poliovirus vaccine combined; 7-valent Streptococcus pneumoniae polysaccharide conjugate vaccine; measles, mumps and rubella vaccine; and varicella vaccine. Coadministration of these vaccines did not interfere with the immunogenicity of the HibMenCY-TT vaccine. Similarly, immune responses to the coadministered vaccines were not affected by the HibMenCY-TT vaccine. The tolerability profile of the HibMen

  15. Voluntary sterilization in Serbia: Unmet need?

    2002-01-01

    Full Text Available Is voluntary sterilization as a birth control method accepted in Serbia? This is certainly a question that is being imposed for research, regardless of the fact that voluntary sterilization is neither accessible nor promoted. Most importantly because there is no understanding in the social nor political sphere for legalization of voluntary sterilization as a form of birth control, apart from the clear necessity for this, first, step. They are: the recognition that voluntary sterilization is an efficient and safe birth control method, respectability of basic human as well as sexual and reproductive rights, spreading of sterilization as a form of birth control among population of both developed and developing countries and an epidemic diffusion of repeated induced abortions in Serbia. Thus individual recognition of the advantages of relying on voluntary sterilization, in a non-encouraging atmosphere, certainly represents one more argument to enable couples to prevent conception by sterilization. Since it was impossible to carry out a representative research among the population of men and women who are at risk for conception, an attempt was made to obtain a reply to the set question among women who decided to induce abortion. It was done out of at least two reasons. The first being that women with induced abortion in their reproductive history were the target group for voluntary sterilization. The second reason was based on the assumption that bringing a decision on induced abortion is preceded by the reconsideration of an earlier adopted strategy regarding children, giving birth and contraception and thus its rational component is revealed more and therefore more easily measurable. The research was carried out in the University Clinic of Obstetrics and Gynecology 'Narodni front' in Belgrade from January 21st o March 1st 2002, and included 296 women. By comparing the social and demographic characteristics of the female respondents, as well as

    1999-01-01

    In this article, the authors discuss the predicament, in Romanian society, of one group that is especially vulnerable to HIV infection and AIDS: men who have sex with men. Such men are driven to secrecy, and discouraged from disclosing themselves even to obtain the help and information they need, because Romanian law prohibits homosexual overtures, denies legal recognition to gay and lesbian organisations, often imposes strong disincentives in the way of those seeking diagnostic tests for HIV or for venereal disease, and still penalizes same sex relations themselves in many circumstances. Social and administrative circumstances in Romania have also aggravated such men's vulnerability. Drawing especially on the United Nations' International Guidelines on HIV/AIDS and Human Rights, the authors offer several recommendations for reform.

    Adult men of different ethnic backgrounds who experienced childhood sexual abuse (CSA) may vary in their reports of the psychological and behavioural impact of CSA on their lives. Empirical studies rarely examine the impact of race/ethnicity or cultural context on the psychological and behavioural struggles of adult male CSA survivors. This study utilised qualitative content analysis to examine the reported CSA-related psychological and behavioural challenges of 150 US men, with equal numbers of Blacks, Latinos and non-Latino Whites. Interview data revealed some ethnic differences: Black men more frequently denied having present day adverse effects than other groups. However, Black men who did report negative consequences of CSA discussed difficulties with substance use and hyper-sexualised behaviour more often than other ethnicities. Latino men reported anger, anxiety, hyper-vigilance, flashbacks and communication problems more often than the other two groups. Black and Latino men also discussed guilt/shame issues and sexual identity concerns more often than Whites did. In contrast, White men more frequently discussed issues related to low self-esteem, loneliness and isolation. These findings suggest that ethnically diverse men may respond differently to CSA experiences and that considerations need to be taken into account when providing healthcare to men with CSA histories.

    Positive reinforcement training (PRT) has successfully been used to train diverse species to execute behaviors helpful in the everyday care and wellbeing of the animals. Because little information is available about training sooty mangabeys (Cercocebus atys atys), we analyzed PRT with a group of 30 adult males as they were trained to shift from 1 side of their enclosure to the other. Over a 4-mo period we conducted 57 training sessions totaling 26.5 h of training and recorded compliance information. During training, compliance increased from 76% of the animals during the first 5 training sessions to 86% of the animals shifting during the last 5 sessions. This result indicated progress but fell short of our goal of 90% compliance. After 25 training sessions, problem-solving techniques were applied to help the consistently noncompliant animals become more proficient. The techniques included reducing social stress by shifting animals so that noncompliant monkeys could shift into an unoccupied space, using more highly preferred foods, and 'jackpot'-sized reinforcement. To determine whether social rank affected training success, animals were categorized into high, medium, and low dominance groups, based on 7 h of behavioral observations. A Kruskal-Wallis test result indicated a significant difference in compliance according to the category of dominance. Although training a group this large proved challenging, the mangabeys cooperated more than 90% of the time during follow-up sessions. The training program improved efficiency in caring for the mangabeys.

    Healthful eating and physical activity are important for healthy weight maintenance. The hypothesis for this study was that college-aged men would perceive factors affecting eating and physical activity as both contributing to and inhibiting healthy weight maintenance. The overall objective was to explore how men view weight maintenance in the context of these aspects. Subjects (n = 47, mean age = 20.3 +/- 1.7 years) completed an online survey, including the 51-item Three-Factor Eating Questionnaire, and participated in 1 of 6 focus groups. Three face-to-face and 3 online synchronous groups were conducted using a 15-question discussion guide to identify weight maintenance issues around eating, physical activity, and body perceptions. Weight satisfaction decreased with increase in both dietary restraint and disinhibition. Number of attempts to lose weight was positively associated with BMI (r [44] = .465, P = .01) and dietary restraint (r [44] = .515, P = .01). Findings from both focus group formats were similar. Motivators (sports performance/fitness, self-esteem, attractiveness, long-term health) were similar for eating healthfully and being physically active; however, more motivators to be physically active than to eat healthfully emerged. Enablers for eating healthfully included liking the taste, availability of healthful foods, using food rules to guide intake, having a habit of healthful eating, and internal drive/will. Barriers to healthful eating included fat in dairy foods, fruit and vegetable taste, and quick spoilage. Barriers to being physically active included lack of time/time management, obligations, being lazy, and girlfriends. Results may be used to inform future obesity prevention interventions.

    Exponential advances have been made regarding computer/Internet technology in the past decade. This growth, in large part, can be attributed to greater access to, affordability of, and anonymity while on the computer. However, this progress has also produced negative psychological issues. Problematic Internet-enabled sexual behavior (IESB) has increasingly affected individuals' family relationships, work productivity, and academic success. This article is the first-known, empirically based outcome study regarding the effectiveness of group therapy treatment for men with problematic IESB. These closed-groups, which ran for 16 weeks, used a combination of Readiness to Change (RtC), Cognitive Behavioral Therapy (CBT), and Motivational Interviewing (MI) interventions. Five groups were analyzed for this paper (yielding a total N of 35), with the average member's age being 44.5 years old. Three different scales (the Orzack Time Intensity Survey, the BASIS-32, and the BDI) were used to track participants' progress across time. The results demonstrated that this group treatment intervention significantly increased members' quality of life and decreased the severity of their depressive symptoms. However, the protocol failed to reduce participants' inappropriate computer use. Regarding comorbidity, the results showed the following: members in the "anxiety" category responded best to the current treatment, those in the "mood" cluster responded relatively positively, and those in the "A-D/HD" category failed to respond significantly. It is clear from this report that more attention must be focused on the treatment of problematic IESB, as opposed to exploratory studies.

  2. "Twelve Angry Men". The Group and the Individual: From Objectiveness to Subjectiveness

    Directory of Open Access Journals (Sweden)

    Eugenio Torre

    2015-12-01

    Full Text Available Screened fiction stirs people’s psyches through emotions, which refer to a virtual world and therefore have the potential to help the individual grow in self-awareness while feeling relatively “safe”. An innovative method to work on movies for education and training purposes was developed by Eugenio Torre, and is proposed here for the film 12 Angry Men. This movie may be used in training settings focused on helping relationships to reflect upon the meaning of being an individual in a group, being a group, responsibility and choice. A key to the reading of the movie is proposed at two different but complementary levels. From an “extra-psychical” standpoint, movie characters may represent a working group of 12 very different people sharing a task, while from an “intra-psychical” one, each character may represent an embodiment or symbol of an individual’s part and/or complex. According to the movie suggestion, we describe a path from objectiveness to subjectiveness and the final accomplishment of an ethical choice.

    Introduction China is amidst a sexual revolution, with changing sexual practices and behaviors. Sex–seeking mobile phone applications (gay apps) that allow multiple people to meet up quickly may facilitate group sex. This study was therefore undertaken to evaluate group sex among Chinese MSM and to better understand factors associated with group sex. Methods An online survey was conducted from September-October 2014, collecting data on socio-demographics, sexual behaviors, use of gay apps and occurrence of group sex among Chinese MSM. Univariate and multivariable logistic regressions were used to compare group sex and non-group sex participants. Results Of the 1,424 MSM, the majority were under 30 years old (77.5%), unmarried (83.9%), and were gay apps users (57.9%). Overall, 141 (9.9%) participants engaged in group sex in the last 12 months. Multivariate analyses showed that men living with HIV, engaged in condomless anal intercourse with men, and used gay apps were more likely to engage in group sex, with adjusted ORs of 3.74 (95% CI 1.92–7.28), 2.88 (95% CI 2.00–4.16) and 1.46 (95% CI: 1.00–2.13), respectively. Among gay app users, the likelihood of group sex increases with the number of sex partners and the number of sex acts with partners met through a gay app. Conclusions Chinese MSM who engage in group sex are also more likely to engage in other risky sexual behaviors, and gay app use may facilitate group sex. Further research is needed among MSM who engage in group sex in order to target interventions and surveillance. PMID:27880823

    Although gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by human immunodeficiency virus (HIV) infection, few test for HIV at regular intervals. Smartphone apps may be an ideal tool to increase regular testing among MSM. However, the success of apps to encourage regular testing among MSM will depend on how frequently the apps are downloaded, whether they continue to be used over months or years, and the degree to which such apps are tailored to the needs of this population. The primary objectives of this study were to answer the following questions. (1) What features and functions of smartphone apps do MSM believe are associated with downloading apps to their mobile phones? (2) What features and functions of smartphone apps are most likely to influence MSM's sustained use of apps over time? (3) What features and functions do MSM prefer in an HIV testing smartphone app? We conducted focus groups (n=7, with a total of 34 participants) with a racially and ethnically diverse group of sexually active HIV-negative MSM (mean age 32 years; 11/34 men, 33%, tested for HIV ≥10 months ago) in the United States in Miami, Florida and Minneapolis, Minnesota. Focus groups were digitally recorded, transcribed verbatim, and deidentified for analysis. We used a constant comparison method (ie, grounded theory coding) to examine and reexamine the themes that emerged from the focus groups. Men reported cost, security, and efficiency as their primary reasons influencing whether they download an app. Usefulness and perceived necessity, as well as peer and posted reviews, affected whether they downloaded and used the app over time. Factors that influenced whether they keep and continue to use an app over time included reliability, ease of use, and frequency of updates. Poor performance and functionality and lack of use were the primary reasons why men would delete an app from their phone. Participants also shared their preferences for an app to

    An emerging HIV epidemic can be seen among men who have sex with men (MSM) in Vietnam. There are currently no evidence-based behavioral sexual risk reduction interventions for MSM in this setting. Between October 2012 and June 2013, 100 high-risk MSM from Ho Chi Minh City were enrolled in an open pilot trial to assess feasibility and acceptability of a group-based, manualized sexual risk reduction intervention, and to preliminarily examine changes in primary and secondary outcomes. Participants completed a behavioral assessment battery and HIV testing at baseline, 3, and 6 months post-baseline.

    The objective of this study was to understand the meaning of hysterectomy according to a group of Chilean men, partners of women who have undergone the procedure (MPWH). This qualitative study was performed with in-depth interviews. A total of 15 men, partners of women who have undergone hysterectomy, were interviewed between May and September of 2010, under the approval of the Ethics Committees. Data analysis was performed using the phenomenological perspective proposed by Giorgi, and content analysis was performed according to Krippendorff. The Crestwell criteria were used to evaluate the trustworthiness of the analysis and guarantee descriptive validity. Five dimensions emerged, which represented unique aspects of hysterectomy according to the men: symptoms, comments, the attributions of the uterus, concerns and changes in sexuality. It is essential to educate MPWH in terms of the support required by women undergoing hysterectomy. Therefore they should be included in the care plan designed for women undergoing hysterectomy.

    Full Text Available Abstract Background Russia has particularly low life expectancy for an industrialised country, with mortality at working ages having fluctuated dramatically over the past few decades, particularly among men. Alcohol has been identified as the most likely cause of these temporal variations. One approach to reducing the alcohol problem in Russia is 'brief interventions' which seek to change views of the personal acceptability of excessive drinking and to encourage self-directed behaviour change. Very few studies to evaluate the efficacy of brief interventions in Russia have been conducted. Motivational Interviewing (MI is a person-centred counselling style which can be adapted to brief interventions in which help is offered in thinking through behaviour in the context of values and goals, to decide whether change is needed, and if so, how it may best be achieved. Methods This paper reports on an individually randomised two-armed parallel group exploratory trial. The primary hypothesis is that a brief adaptation of MI will be effective in reducing self-reported hazardous and harmful drinking at 3 months. Participants were drawn from the Izhevsk Family Study II, with eligibility determined based on proxy reports of hazardous and harmful drinking in the past year. All participants underwent a health check, with MI subsequently delivered to those in the intervention arm. Signed consent was obtained from those in the intervention arm only at this point. Both groups were then invited for 3 and 12 month follow ups. The control group did not receive any additional intervention. Results 441 men were randomised. Of these 61 did not have a health check leaving 190 in each trial arm. Follow up at 3 months was high (97% of those having a health check, and very similar in the two trial arms (183 in the intervention and 187 in the control. No significant differences were detected between the randomised groups in either the primary or the secondary outcomes at

    Group sex events are an epidemiologically important part of some gay and bisexual men's sexual culture in Canada. Associated with condomless anal intercourse and polysubstance use, such events have been cited as disproportionally contributing to HIV infection rates. We analysed questionnaire data from the Momentum Health Study in Vancouver, Canada, to understand substance use, sexual behaviour, psychosocial variables (Sexual Sensation Seeking, Sexual Escape Motivation, Treatment Optimism) and HIV prevention strategies (sero-sorting, strategic positioning, avoiding anal sex, disclosure, treatment as prevention) of men attending such events, which were defined as group (n ≥ 4 partners) sex parties, blackout events and darkrooms. Analysis by multivariable logistic regression compared men attending group sex events within the past six months (n = 180) with non-attendees (n = 539). Results showed that attendees reported: (1) significantly higher use of sex drugs and alcohol consumption, (2) higher scores on the Sexual Sensation Scale, more anal sex partners, greater odds of any condomless anal sex with sero-discordant partners and greater odds of reporting fisting and sex toy use and (3) different prevention practices that varied by HIV-serostatus. Findings are interpreted in light of the importance of pleasure, sociality and HIV/STI prevention strategies associated with group sex events. Findings contribute to the development of appropriate education and intervention for attendees.

    To assess the prevalence of chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS) symptoms in a large group of men, using the National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and to evaluate which of the NIH-CPSI symptoms had the most detrimental effect on quality of life (QoL). The NIH-CPSI was completed by 1273 men during a male-health promotion event. The presence of CP/CPPS-like symptoms was defined according to the NIH-CPSI criteria (perineal pain or ejaculatory pain and NIH-CPSI-pain score >/= 4). Finally, using linear regression analyses we evaluated the effect of each questionnaire symptom on the NIH-CPSI-QoL domain. The mean (range) age of the men was 57.6 (40-89) years; 133 (10.5%) reported CP/CPPS-like symptoms, with 62 (4.9%) reporting mild and 71 (5.6%) reporting moderate to severe CP/CPPS-like symptoms. Men with CP/CPPS-like symptoms had higher NIH-CPSI-QoL scores, showing a greater detriment of QoL (4.9 vs 2.5; P patients.

    We investigated whether expressing anger increases social influence for men, but diminishes social influence for women, during group deliberation. In a deception paradigm, participants believed they were engaged in a computer-mediated mock jury deliberation about a murder case. In actuality, the interaction was scripted. The script included 5 other mock jurors who provided verdicts and comments in support of the verdicts; 4 agreed with the participant and 1 was a "holdout" dissenter. Holdouts expressed their opinions with no emotion, anger, or fear and had either male or female names. Holdouts exerted no influence on participants' opinions when they expressed no emotion or fear. Participants' confidence in their own verdict dropped significantly, however, after male holdouts expressed anger. Yet, anger expression undermined female holdouts: Participants became significantly more confident in their original verdicts after female holdouts expressed anger-even though they were expressing the exact same opinion and emotion as the male holdouts. Mediation analyses revealed that participants drew different inferences from male versus female anger, which created a gender gap in influence during group deliberation. The current study has implications for group decisions in general, and jury deliberations in particular, by suggesting that expressing anger might lead men to gain influence, but women to lose influence over others (even when making identical arguments). These diverging consequences might result in women potentially having less influence on societally important decisions than men, such as jury verdicts.

    The present study sought to examine the interactive effects of an external locus of control and interaction in a negative peer group climate on men's perpetration of physical aggression and infliction of injury toward their female intimate partners. Participants were 206 heterosexual males recruited from the metro-Atlanta community who completed self-report measures of external locus of control, involvement in a negative peer group climate, and physical aggression and infliction of injury against intimate partners during the past 12 months. Negative peer group climate was conceptualized as a peer group that displays behavior which may instigate aggressive norms, attitudes, and behaviors. Results indicated that men with an external locus of control were more likely to perpetrate physical aggression toward and inflict injury on their intimate partners if they reported high, but not low, involvement in a negative peer group climate. These results extend current research suggesting external locus of control as a risk factor for intimate partner aggression by highlighting the impact of negative peer groups. Implications and future intervention research are discussed.

     To compare the effectiveness of flexible sigmoidoscopy in screening for colorectal cancer by patient sex and age.  Pooled analysis of randomised trials (the US Prostate, Lung, Colorectal and Ovarian cancer screening trial (PLCO), the Italian Screening for Colon and Rectum trial (SCORE), and the Norwegian Colorectal Cancer Prevention trial (NORCCAP)).  Aggregated data were pooled from each randomised trial on incidence of colorectal cancer and mortality stratified by sex, age at screening, and colon subsite (distal v proximal).  Invited individuals aged 55-74 (PLCO), 55-64 (SCORE), and 50-64 (NORCCAP). Individuals were randomised to receive flexible sigmoidoscopy screening once only (SCORE and NORCCAP) or twice (PLCO), or receive usual care (no intervention).  287 928 individuals were included in the pooled analysis; 115 139 randomised to screening and 172 789 to usual care. Compliance rates were 58%, 63%, and 87% in SCORE, NORCCAP, and PLCO, respectively. Median follow-up was 10.5 to 12.1 years. Screening reduced the incidence of colorectal cancer in men (relative risk 0.76; 95% confidence interval 0.70 to 0.83) and women (0.83; 0.75 to 0.92). No difference in the effect of screening was seen between men younger than 60 and those older than 60. Screening reduced the incidence of colorectal cancer in women younger than 60 (relative risk 0.71; 95% confidence interval 0.59 to 0.84), but not significantly in those aged 60 or older (0.90; 0.80 to 1.02). Colorectal cancer mortality was significantly reduced in both younger and older men, and in women younger than 60. Screening reduced colorectal cancer incidence to a similar extent in the distal colon in men and women, but there was no effect of screening in the proximal colon in older women with a significant interaction between sex and age group (P=0.04).  Flexible sigmoidoscopy is an effective tool for colorectal cancer screening in men and younger women.

    This survey shows that female representation in boards and management groups of large energy companies in Germany, Spain and Sweden is far from being gender-equal. Of the 464 companies surveyed, 295 (64%) had no women at all in boards or management groups and only 5% could be considered gender-equal by having 40% or more women in such positions. Interviews with energy companies confirmed current trends that gender equality efforts within decision-making in business are weak or non-existent. The findings are discussed against the background of differences in risk perceptions among women and men, evidence of women's impact on boards and companies' performance and the substantial risks related to unabated climate change. Research is suggested for exploring potential impacts on energy companies' performance with more women in the boards when it comes to mitigation activities. (author)

    Full Text Available Introduction: Many healthy elderly Indian men seek surgical treatment for localized prostate cancer. Quite often, radical surgery is not offered to the patients over 70 years of age due to the perception of increased side-effects and complications. We have previously reported our results of robotic radical prostatectomy in a study comprising 150 Indian patients, where almost a quarter of patients were elderly. This subgroup analysis was therefore focused on evaluating perioperative and continence outcomes in elderly men (≥70 years with localized prostate cancer. Materials and Methods: Between April 2010 and August 2013, 153 men had robot-assisted radical prostatectomy performed by two surgeons. Of the 150 men analyzed, 39 (26% were aged ≥70 years. All patients underwent robotic prostatectomy using a 4 arm da Vinci surgical system. Pre-operative, intraoperative and post-operative parameters were studied. Check cystogram was performed in all patients prior to catheter removal. Complications were categorized using the Clavien-Dindo classification system. Continence was defined as use of "no pad" or security liner only. All data were recorded prospectively and analyzed using SPSS version 20. Results: There were no significant intraoperative or perioperative complications in this group. Median blood loss during surgery was 150 mL. None of the patient required blood transfusion. There were two minor complications (5.1% within the first 30 days of surgery: Minimal anastomotic site leak (one patient requiring replacement and prolongation of Foley′s drainage by 1 week and ileus (one patient. No patient had any cardiopulmonary or vascular complications in the post-operative period. The median duration of hospital stay was 3 days. The median duration of catheterization was 7 days. No patient had problem of bladder neck stenosis in the follow-up period. At 1 month, 3 months, 6 months and 1 year of follow-up, 66.7% (n = 26, 74.3% (n = 29, 87.9% (n = 34

    People remanded into custody by the courts have a substantially higher rate of severe mental disorder than other prisoners and the general population. Knowledge of their prevalence, needs and characteristics and an analysis of pathways to care may be necessary to provide mental health care effectively and efficiently. Previous prison studies focusing on psychotic offenders have suffered from the use of instruments not validated in a forensic setting and lack of a relevant comparison group. The Diagnostic Interview for Psychosis (DP) is a composite semi-structured standardized interview schedule. It combines social and demographic descriptors with measures of functioning adapted from the World Health Organisation Disability Assessment Schedule (DAS). The remand centre surveyed had 466 cells and is the main remand and reception centre for males for the southern region of the state of Queensland, Australia. Of the 621 men screened, 65 answered yes to at least one question in the DP and were interviewed. Six hundred and twenty-one remandees were screened and of these 61 were interviewed as screened positive for psychotic disorder. Thirty-five per cent had been homeless for an average of 32 weeks during the previous year. Most had had little contact with families or close friends. Eighty-one per cent were receiving no treatment at the time of offence. Seventy-eight per cent were unemployed and in receipt of a pension. Eighty per cent were dependent on alcohol, cannabis or amphetamines. Statistical issues of power are detailed in the text. The simplistic 'prison, hospital or community treatment' debate is misleading. Instead, the development of flexible preventative, management and accommodation services for people with severe mental disorder who have committed offences is a priority.

  5. Neural activation during submaximal contractions seems more reflective of neuromuscular ageing than maximal voluntary activation

    2016-02-01

    Full Text Available This study aimed at testing the hypothesis that differences in neural activation strategy during submaximal but not maximal plantarflexions exist between young and older men. Eleven young men (YM, 26±4 yr and 13 OM (76±3 yr volunteered for the investigation. Maximal voluntary torque (MVT was 38.2%, lower (P<0.001 in OM than in YM, while voluntary activation was equivalent (~97%. The relationship between the interpolated twitch-torque and the voluntary torque (IT-VT relationship was composite (curvilinear+exponential for both age-groups. However, the OM showed accentuated concavity, as attested by the occurrence of the deviation from linearity at a lower contraction intensity (OM: 54.9 vs. YM: 71.9% MVT. In conclusion, ageing does not affect the capacity to fully activate the plantar flexors during maximal performances, but it alters the activation pattern for submaximal levels of effort. The greater age-related concavity of the IT-VT relationship suggests that, during submaximal contractions, OM need to reach a level of activation higher than YM to develop an equivalent relative torque.

    Our goal in this article is to explicate the way, and the extent to which, euthanasia can be voluntary from both the perspective of the patient and the perspective of the health care providers involved in the patient's care. More significantly, we aim to challenge the way in which those engaged in ongoing philosophical debates regarding the morality of euthanasia draw distinctions between voluntary, involuntary, and nonvoluntary euthanasia on the grounds that drawing the distinctions in the traditional manner (1) fails to reflect what is important from the patient's perspective and (2) fails to reflect the significance of health care providers' interests, including their autonomy and integrity.

    This study investigates the impact of a weekly group providing sport and physical activities for men with early onset dementia established by Notts County Football in the Community (NCFC). There were three aims: to investigate the effect of early onset dementia on individuals with the condition and their carers; to examine the perceptions of current levels of service provision for people with early onset dementia; and to analyse the impact of the group. Men with dementia (n = 5) attending the sessions, their carers (n = 5), NCFC coaching staff (n = 5) and people organizing/facilitating the sessions (n = 5) were interviewed. Semi-structured interviews explored the participants' experiences of dementia, their opinions on current service provisions and on the sessions. Data were analysed using thematic analysis. Four main themes were found: loss related to the condition of dementia and its impact on relationships ('Loss'); lack of age-appropriate services for people with early onset dementia ('Lack of Resources'); enjoyment and positive anticipation related to the group for all involved ('Enjoyment and Anticipation'); and 'the Notts County Effect' which attributed the success of the sessions to the strong brand of the football club, and to personalized service in a "dementia-free" environment. The NCFC sessions provided a safe low-cost intervention with positive effects upon quality of life for both people with early onset dementia, their carers and the staff involved. This suggests that the service may be valuable to a wider range of people living in different areas.

  8. Enhanced efficiency of female-to-male HIV transmission in core groups in developing countries: the need to target men.

    The spread of heterosexual HIV in developing countries is heterogeneous. Factors that explain the wide diversity of HIV prevalences in different countries are undetermined. International aid organizations currently appear to be focusing activities mainly on women rather than on men. To identify critical determinants contributing to the high rates of heterosexual HIV transmission in developing countries through a review of studies investigating HIV per-act transmission rates, and to discuss how these factors might be prioritized through HIV-prevention interventions. Studies investigating the per-act HIV transmission rate were identified through a MEDLINE search and a review of the abstracts of the Annual International AIDS Conferences. When the summary mean per-act HIV transmission rates were calculated, the ratio of female-to-male HIV transmission in developing countries compared with that in the developed world was 341, whereas that for male-to-female transmission was 2.9. Enhanced female-to-male HIV transmission in male core groups is a critical determinant of high-prevalence HIV epidemics among heterosexuals in developing countries. In addition to condom promotion, there is a need for an increased emphasis on HIV-prevention activities in men to decrease their susceptibility in developing countries, particularly in the countries most affected by the epidemic.

    Full Text Available Background: The biological mechanism of circumcision as potentiating HIV prevention is poorly understood. Foreskin microbiota has been postulated as having a potential role; however, little is known about the relationship between bacterial pathogens and circumcision in adults. Materials and Methods: We sampled the coronal sulcus of a diverse group of circumcised and uncircumcised men (n=315 from a government chest hospital and fertility clinic in Hyderabad, Andhra Pradesh, India. Genital examination was conducted on three groups of men: Group 1 - HIV infected; Group 2 - TB infected; Group 3 - control. Aerobic and anaerobic specimens were cultured according to standard clinical protocols, and results were analyzed following multivariate logistic regression models. Results: Three hundred fifteen study participants - 47.6% of Group 1, 36.5% of Group 2, and 15.9% of Group 3 - were enrolled in the study and included in all analyses. Overall 37.1% of the participants were circumcised without variation across groups (P=0.29. Smegma was observed in 18.7% of the participants with no cases observed in Group 3 (P<0.001. Gram-negative pathogens were more prevalent among study participants in Group 1 (22.7% and Group 2 (30.4% as compared with those in Group 3 (6.0% (P=0.003. In multivariate regression analysis, controlling for group, age, and presence of smegma, uncircumcised men were more likely to be colonized with gram positives [Adjusted Odds Ratio (AOR 1.9; P<0.05], gram negatives (AOR 2.4; P<0.05, or any pathogen (AOR 2.8; P<0.005. Conclusions: Uncircumcised men in this population in South India are more likely to harbor bacterial pathogens in the coronal sulcus than do their circumcised counterparts. Future studies should examine the relationship between foreskin microbiota and HIV transmission.

    Full Text Available Introduction: Blood transfusions form a crucial and irreplaceable part in the medical management of many diseases. The collection of blood from voluntary, non-remunerated blood donors from low risk populations is an important measure for ensuring the availability and safety of blood transfusion. In a state like Uttarakhand which is visited by lakhs of visitors during pilgrimage season and where natural calamities and accidents are very common, the availability of blood is of utmost importance. Aim: To find out knowledge, attitude and practices of people towards voluntary blood donation to comprehend the situation and find ways to enhance voluntary blood donation in the state of Uttarakhand. Materials and Methods: Multi stage methodology was designed to target population including general population, influencers (doctors and supporting organizations (camp organizers, State AIDS Control Society Officials who were subjected to in-depth interview using pre-structured questionnaires to assess knowledge/awareness about voluntary blood donation, factors preventing and source of knowledge about voluntary blood donation. Result: The sample population consisted of mostly men (67% in the age-group of 26-35 years. Requirement of blood and the measures to promote voluntary blood donation have a direct relationship with the total population and literacy level of the population. Awareness about blood donation, source of knowledge about blood donation, reasons for not donating blood are particularly stressed. With increase in educational level, the awareness level was also found to increase. While among illiterates 81 percent of the respondents knew about blood donation, among the post graduates the same ratio was found to be almost cent-percent. Among various reasons cited for not donating blood, lack of awareness being the most common reason.

The sample population consisted of mostly men (67%) in the age-group of 26-35 years. Requirement of blood and the measures to promote voluntary blood donation have a direct relationship with the total population and literacy level of the population. Awareness about blood donation, source of knowledge about blood donation, reasons for not donating blood are particularly stressed. With increase in educational level, the awareness level was also found to increase. While among illiterates 81 percent of the respondents knew about blood donation, among the post graduates the same ratio was found to be almost cent-percent. Among various reasons cited for not donating blood, lack of awareness being the most common reason. People gathered information about blood donation from several different sources with electronic media being the most prominent. This study illustrates how increasing awareness and

    Urinary tract infections (UTI), which are mostly caused by Escherichia coli, are an important public health problem worldwide. Although men experience diverse UTI syndromes, there have been relatively few molecular-epidemiological studies of UTI pathogenesis in men. We studied the distribution of 22 E. coli virulence factor (VF) genes, major phylogenetic groups, sequence type ST131, and UTI-associated O antigens among 101 pyelonephritis, 153 cystitis and 135 fecal healthy control E. coli isolates from men aged 30-70 years in a regional area of NSW, Australia. Overall, the studied traits exhibited a prevalence gradient across these groups, highest in pyelonephritis, intermediate in cystitis, and lowest among fecal isolates. Differences in virulence gene prevalence between cystitis and pyelonephritis isolates were limited to eight genes. The UTI-associated O antigens were also distributed widely, but types O6, O25 and O75 were significantly associated with pyelonephritis. The ST131 clonal group, which accounted for 13% of isolates overall (22% of group B2 isolates), likewise exhibited a significant descending prevalence gradient from pyelonephritis (36%), through cystitis (8%), to fecal (0%) isolates. These findings contribute to better understanding of the pathogenesis of UTIs in men and identify specific VF genes and O types, and a prominent clonal group (ST131), as being important in UTI pathogenesis in this population. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    Gavage is a widely performed technique for daily dosing in laboratory rodents. Although effective, gavage comprises a sequence of potentially stressful procedures for laboratory animals that may introduce bias into experimental results, especially when the drugs to be tested interfere with stress-dependent parameters. We aimed to test vehicles suitable for drug delivery by voluntary ingestion in rats. Specifically, Male Wistar rats (age, 2 to 3 mo) were used to test nut paste (NUT), peanut butter (PB), and sugar paste (SUG) as vehicles for long-term voluntary oral administration of losartan, an angiotensin II receptor blocker. Vehicles were administered for 28 d without drug to assess effects on the glucose level and serum lipid profile. Losartan was mixed with vehicles and either offered to the rats or administered by gavage (14 d) for subsequent quantification of losartan plasma levels by HPLC. After a 2-d acclimation period, all rats voluntarily ate the vehicles, either alone or mixed with losartan. NUT administration reduced blood glucose levels. The SUG group had higher concentrations of losartan than did the gavage group, without changes in lipid and glucose profiles. Our results showed that NUT, PB, and SUG all are viable for daily single-dose voluntary ingestion of losartan and that SUG was the best alternative overall. Drug bioavailability was not reduced after voluntary ingestion, suggesting that this method is highly effective for chronic oral administration of losartan to laboratory rodents.

    Studies examining associations between racial discrimination and cardiovascular health outcomes have been inconsistent, with some studies finding the highest risk of hypertension among African Americans who report no discrimination. A potential explanation of the latter is that hypertension and other cardiovascular problems are fostered by internalization and denial of racial discrimination. To explore this hypothesis, the current study examines the role of internalized negative racial group attitudes in linking experiences of racial discrimination and history of cardiovascular disease among African American men. We predicted a significant interaction between reported discrimination and internalized negative racial group attitudes in predicting cardiovascular disease. Weighted logistic regression analyses were conducted among 1216 African American men from the National Survey of American Life (NSAL; 2001-2003). We found no main effect of racial discrimination in predicting history of cardiovascular disease. However, agreeing with negative beliefs about Blacks was positively associated with cardiovascular disease history, and also moderated the effect of racial discrimination. Reporting racial discrimination was associated with higher risk of cardiovascular disease among African American men who disagreed with negative beliefs about Blacks. However, among African American men who endorsed negative beliefs about Blacks, the risk of cardiovascular disease was greatest among those reporting no discrimination. Findings suggest that racial discrimination and the internalization of negative racial group attitudes are both risk factors for cardiovascular disease among African American men. Furthermore, the combination of internalizing negative beliefs about Blacks and the absence of reported racial discrimination appear to be associated with particularly poor cardiovascular health. Steps to address racial discrimination as well as programs aimed at developing a positive

    Local beliefs and practices about voluntary medical male circumcision (VMMC) may influence uptake and effectiveness. Data were gathered through interviews with 40 people from four ethnically mixed fishing communities in Uganda. Some men believed that wound healing could be promoted by contact with vaginal fluids while sex with non-regular partners could chase away spirits - practices which encouraged unsafe sexual practices. Information given by providers stressed that VMMC did not afford complete protection from sexually-transmitted infections, however, a number of male community members held the view that they were fully protected once circumcised. Both men and women said that VMMC was good not just for HIV prevention but also as a way of maintaining hygiene among the men. The implementation of VMMC in high-HIV prevalence settings needs to take account of local beliefs about circumcision, working with local religious/social group leaders, women and peers in the roll-out of the intervention.

    Incomplete voluntary muscle activation may contribute to impaired muscle mechanical function and physical function in older adults. Exercise interventions have been shown to increase voluntary muscle activation, although the evidence is sparse for mobility-limited older adults, particularly in association with physical function. This study examined the effects of 12weeks of power training on outcomes of voluntary muscle activation and gait speed in mobility-limited older adults from the Healthy Ageing Network of Competence (HANC) study. We included 37 older men and women with a usual gait speed of analysis: n=16 in the training group (TG: 12weeks of progressive high-load power training, 2 sessions per week; age: 82.3±1.3years, 56% women) and n=21 in the control group (CG: no interventions; age: 81.6±1.1years, 67% women). Knee extensor muscle thickness (ultrasonography), strength (isokinetic dynamometry), voluntary activation (interpolated twitch technique), and gait speed (2-min maximal walking test) were assessed at baseline and post-intervention. At baseline, TG and CG were comparable for all measures. Post-intervention, significant between-group changes (TG vs. CG; pgait speed (+0.12m/s), whereas the between-group change in muscle thickness was non-significant (+0.08cm). Improvements in voluntary muscle activation were associated with improvements in gait speed in TG (r=0.67, ppower training, and is associated with improved maximal gait speed. Incomplete voluntary muscle activation should be considered one of the key mechanisms influencing muscle mechanical function and gait speed in older adults.

    2000-06-01

    David Lykken's proposal to license married parents for child rearing, and to deny the same opportunity to single and inept parents, springs from his deep concern for millions of youngsters cruelly subjected to abusive and neglectful rearing circumstances. Children from such inadequate homes grow up to have high rates of school failure, criminality, and drug addiction. The problem is clear, but Lykken's remedies of mandated marriage and parental licensure are unacceptable in U.S. society, where our reproductive rights are fortunately protected by our Constitution. As a devoted proponent of reproductive rights, I propose a legally and morally acceptable proposal to the same end. Increasing women's effective control of reproduction and moving toward entirely voluntary parenthood will accomplish the same goals without compromising our civil liberties.

    This study was undertaken from 2009-2011 to understand the association between body mass index (BMI) and blood pressure (BP) (systolic or SBP and diastolic or DBP) among randomly chosen men, aged 30 to 59 years, of three endogamous communities in Darjeeling, West Bengal, India: Dhimal (n = 88), Mech (n = 71), and Rajbanshi (n = 83). Analysis of variance was applied. Remarkable rates of BMI-based undernutrition (chronic energy deficiency or CED) were recorded among Dhimals (31%) and Rajbanshis (18%). Notable prevalence of overweight (20%) was recorded among men of Mech community. None were found to be obese in three samples. Mean SBP and DBP were found to rise consistently at levels of BMI (undernutrition, normal, and overweight). BMI was observed to rise consistently at levels of blood pressures (normotensive, prehypertensive, and hypertensive). Among Mech, this pattern was found to be more conspicuous. DBP was found to be more sensitive with changes of BMI in men.

    Full Text Available Background: The relationship between tobacco and alcohol use is very important in making strategies containing use of these products. Alcohol and tobacco use were studied separately in Indian studies, which can undermine their co-occurrences. The objective of the study is to know the prevalence and socio-economic determinants of co-occurrence of alcohol and tobacco use among men in working age groups.Data Sources: The data from the Study on Global Ageing and Adult Health (SAGE Wave1 was used. It was a cross sectional household survey, which collected information for adults aged 18 years and above.Results: The prevalence of co-use of tobacco and alcohol among men aged 18-59 years was 23.5%. High use of tobacco was found among alcohol user. Age cohorts were also the important determinants of alcohol and tobacco use. The inverted U or V-shape relation was found between age groups and co-use of tobacco and alcohol. The prevalence was lowest for age groups 18-24 years and 50-59 years. Low education attainment and working in informal sector were the main risk factors for high co-use of these substances among men. The study also tried to look at the relationship between the co-use of alcohol and tobacco with some selected health indicators. Use of alcohol and tobacco was significantly related with under nutrition and increasing blood pressure levels among men in India.Conclusion: To contain the use of alcohol and tobacco to improve heath condition among adult men, policies and strategies must be form keeping the importance of their co-occurrences.

    Sexually transmitted infections (STIs) affect sexual and reproductive health of millions of men. Pathogens such as human papillomavirus (HPV), herpes simplex virus type 1 and 2 (HSV-1 y HSV-2), Chlamydia trachomatis,Mycoplasmagenitalium,Mycoplasma hominis and Ureaplasma urealyticum are associated with STIs. To detect pathogens associated with STIs in symptomatic men and its relationship with sexual behavior. DNA was obtained from exfoliated cells of penis from 20 symptomatic men. Pathogens were detected using qPCR or PCR followed by reverse line blot. Sexual behavior was evaluated through a survey. Two or more infectious agents were detected in 50% of samples. U. urealyticum was found in 25%, meanwhile C. trachomatis and M. hominis were detected in 15%. VHS-1, VHS-2 andM. genitalium were detected only in 5%. HPV was found in all samples. The most frequent HPV genotypes were VPH 16, 11, 70. There were no statistical link found between sexual behavior and the studied microorganisms Conclusion: Infectious agents associated with STIs were detected in symptomatic men. HPV was the most frequent pathogen and it was detected in multiple genotypes. It is necessary to increase the sample size to associate significantly the sexual behavior with the results.

  12. From mandatory to voluntary testing: balancing human rights, religious and cultural values, and HIV/AIDS prevention in Ghana.

    This paper examines efforts by some churches in Ghana to reduce the spread of HIV/AIDS. The analysis is based on focus group discussions with two groups of men and two groups of women, along with in-depth interviews with 13 pastors and marriage counsellors in the churches studied. In response to government and public criticisms about human rights violations, churches that previously imposed mandatory HIV testing on members planning to marry now have voluntary testing programmes. However, the results suggest that what the churches refer to as voluntary testing may not be truly voluntary. Cultural values and traditional practices, including traditional courtship and marriage rites (which are performed before church weddings), not only clash with considerations about pre-marital HIV testing but also complicate the contentious issue of confidentiality of information on HIV testing. Associated with these complexities and issues of confidentiality is a reluctance among participants, particularly those from northern Ghana, to test for HIV. The results reveal how broader social impacts of HIV testing for those planning to marry may extend beyond individuals or couples in different cultural contexts. The findings also support the general view that there are no perfect or easy solutions to combating the HIV/AIDS pandemic. Practical solutions and programs for Ghana cannot be neutral to cultural values and need to be tailored for particular (ethnic) populations.

    Voluntary medical incident reports lacking consistency and accuracy impede the ultimate use of the reports for patient safety research. To improve this, two coders examined harm score usage in a voluntary medical incident reporting system where the harm scores were selected from a predefined list by different reporters. The two coders inter-rater agreement percent was 82%. The major categories and reviewed harm score jointly demonstrate that this process is critical and necessary in preparing the voluntary reports for further content and semantics analysis.

    This paper sheds new light on the economic logic of voluntary associations and the relationship between individual contribution and collective action. The aims are twofold. Firstly, we seek to explain how "team reasoning" (Bacharach et al. 2006) can deeply change the functioning of voluntary associations (which are considered to produce a public good) when some or all of the individual members group together to make collective decisions about their involvement or contribution, rather than dec...

    2016-08-01

    Full Text Available Background: In Algeria, the data on infertility and its various causes are rare. Recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. Knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyotype analysis in Algerian infertile men, using peripheral blood lymphocytes.Methods: A cytogenetic study was conducted on 10 men from infertile couples by Karyotype analysis of R-banding performed by lymphocyte culture technique. Fluorescence in situ hybridization was performed and molecular abnormalities were investigated by polymerase chain reaction. Follicle stimulating hormone (FSH and luteinizing hormone (LH levels were evaluated by immunoradiometric method.Results: Chromosomal abnormalities were observed in 30% of the patients. We identified a homogenous Klinefelter syndrome patient with 47, XXY karyotype, a mosaic Klinefelter syndrome patient with 47, XXY/46, XY karyotype and a 46, XX male. Fluorescence in situ hybridization showed that the sex-determining region Y was translocated to the short arm of the X chromosome in patient with 46, XX chromosomal constitution and the presence of the SRY gene was confirmed by polymerase chain reaction and electrophoresis.Conclusion: The occurrence of chromosomal abnormalities in 30% of the infertile men strongly supports the inclusion of routine cytogenetic testing for diagnostic establishment and suitable counseling for couples seeking for assisted reproduction technologies. Keywords: Male infertility, Cytogenetic, Azoospermia, Severe oligozoospermia

  16. A comparison of adductor pollicis fatigue in older men and women.

    Cheng, Arthur; Ditor, David S; Hicks, Audrey L

    2003-09-01

    Sex differences in fatigue resistance of the adductor pollicis (AP) muscle were studied in 24 older adults who were divided into three groups: 12 older men (69.8 +/- 4.60 years), 6 older women not on hormone replacement therapy (HRT) (70.2 +/- 4.02 years), and 6 older women on HRT (68.7 +/- 6.47 years). Fatigue in the AP muscle was induced using an intermittent (5 s contraction, 5 s rest) submaximal voluntary contraction (50% of maximal voluntary contraction (MVC)) protocol, which was continued until exhaustion (i.e., when subjects could either no longer maintain a 5-s contraction at 50% MVC or when the MVC was deemed to be lower than the target force). There was no effect of HRT on MVC or time to fatigue (TTF); therefore, the older women were pooled as one subject group. At baseline, men were stronger than women for MVC (75.9 +/- 18.8 N in men vs. 56.8 +/- 10.0 N in women; P 0.20), nor was there a significant relationship between baseline muscle force and TTF (r = 0.14). There was also no difference in the pattern of fatigue and recovery between the men and women. These results suggest that there is no difference in endurance or fatigue characteristics of the AP muscle in men and women over the age of 65 years, and that baseline muscle force does not predict fatigue resistance in this muscle.

  17. Comparing Voluntary and Mandatory Gameplay

    Directory of Open Access Journals (Sweden)

    Esther Kuindersma

    2016-09-01

    Full Text Available Gameplay is commonly considered to be a voluntary activity. Game designers generally believe that voluntary gameplay is essentially different from mandatory gameplay. Such a belief may be a challenge for serious games, as instruction is usually mandatory. The article describes the outcomes of two experiments on the impact of voluntariness on the learning effect and enjoyment of a serious game. In the first experiment freedom of choosing to play a serious game was studied, with participants who had volunteered to participate. The results suggested that, contrary to the opinion of many game designers, being required to play a serious game does not automatically take the fun out of the game. The second experiment had voluntary participants and mandatory participants, who had to participate as part of a homework assignment. The outcomes show that mandatory participants enjoyed the game as much as the voluntary participants, even if they had to play the game for a minimum required time. These studies indicate that mandatory gameplay does not reduce enjoyment and learning effect.

  18. Voluntary organisation and adult education

    1998-12-01

    Full Text Available The author starts by offering a definition of voluntary organisations. He then discusses their importance and role, focusing on the issue of adult education wi­ thin these organisations. He also wells upon learning and change of voluntary organisation members, making use of the results of a study he conducted together with his collaborators. One of their fin­dings has been that voluntary organisati­ons, due to their organisational targets li­ke painting, singing or caring for people in need, lead their members to learning, i.e. essentially content learning. Moreo­ver, voluntary organisations offer a fair number of opportunities for social lear­ning and change. ln spite of the fact that the respondents were mostly not aware of the outcomes of their learning and change, careful listeners conducting the interview made them understand the im­portance of the learning they had gone through. The author concludes by poin­ ting out that formal education of adults can get its inspiration in learning in voluntary organisations. On the other hand, such learning would benefit greatly from findings and methods of formal education of adults.

    Management of insulinomas in the context of MEN1 remains poorly studied. The aim of this study was to evaluate long-term results of various surgical approaches in a large cohort of insulinoma-MEN1 patients. Consecutive insulinoma-MEN1 patients operated on for a nonmetastatic insulinoma between 1957 and 2010 were retrospectively selected from the MEN1 database of the French Endocrine Tumor Group. The type of surgery was categorized as distal pancreatectomy (DP), total pancreatectomy/cephalic duodenopancreatectomy (TP/CDP), or enucleation (E). Primary endpoint was time until recurrence of hypoglycemia after initial surgery. Secondary endpoints were post-operative complications. The study included 73 patients (median age=28 years). Surgical procedures were DP (n=46), TP/CDP (n=9), or E (n=18). After a median post-operative follow-up of 9.0 years (inter-quartile range (IQR): 2.5-16.5 years), 60/73 patients (82.2%) remained hypoglycemia free. E and TP/CDP were associated with a higher risk of recurrent hypoglycemia episodes (unadjusted hazard ratio: 6.18 ((95% CI: 1.54-24.8); P=0.010) for E vs DP and 9.51 ((95% CI: 1.85-48.8); P=0.007) for TP/CDP vs DP. After adjustment for International Union against Cancer pTNM classification, enucleation remained significantly associated with a higher probability of recurrence. Long-term complications had occurred in 20 (43.5%) patients with DP, five (55.6%) with TP/CDP, but in none of the patients who have undergone E (P=0.002). In the French Endocrine database, DP is associated with a lower risk for recurrent hypoglycemia episodes. Due to lower morbidity, E alone might be considered as an alternative. © 2015 European Society of Endocrinology.

    The purpose of this study was to explore the perceptions of violence against women (VAW) held by Haitian men to gain a better understanding of why VAW occurs. Women in Haiti have experienced significant violence, both before and following the 2010 earthquake. Fifteen men aged 26 to 47 participated in a focus group. The data revealed three themes: men's beliefs about VAW and its context, factors influencing VAW, and recommended interventions. When approaching VAW, men must be part of the collective effort. Their insights are valuable when planning and implementing interventions to decrease VAW in Haiti and worldwide.

    To determine the frequency of genetic alterations in a population of Brazilian infertile men with severe oligozoospermia or non-obstructive azoospermia. Retrospective study of a group of 143 infertile men with severe oligozoospermia or non-obstructive azoospermia from the Andrology Outpatient Clinic of the Human Reproduction Service at the ABC School of Medicine. Of these patients, 100 had severe oligozoospermia, and 43 non-obstructive azoospermia. All patients underwent a genetic study which included karyotype analysis and Y-microdeletion investigation. Genetic abnormalities were found in 18.8% of the studied patients. Chromosomal abnormalities were found in 6.2% of the patients, being more prevalent in the azoospermia group (11.6%) than in the oligozoospermia group (4%). Chromosomal variants were found in 8.3%, and Y-chromosome microdeletions in 4.2% of patients. The high frequency of genetic alterations (18.8%) in our series justified performing a genetic investigation in a population with idiopathic infertility, as results may help determine the prognosis, as well as the choice of an assisted reproduction technique. Moreover, a genetic investigation could minimize the risk of transmitting genetic abnormalities to future generations such as genetic male infertility, mental retardation, genital ambiguity and/or birth defects.

    Emerging research supports the notion that sexual compulsivity (SC) and hypersexual disorder (HD) among gay and bisexual men (GBM) might be conceptualized as comprising three groups-Neither SC nor HD; SC only, and Both SC and HD-that capture distinct levels of severity across the SC/HD continuum. We examined data from 370 highly sexually active GBM to assess how the three groups compare across a range of risk factors for HIV infection. Comparisons focused on psychosexual measures-temptation for condomless anal sex (CAS), self-efficacy for avoiding CAS, sexual excitation and inhibition-as well as reports of actual sexual behavior. Nearly half (48.9 %) of this highly sexually active sample was classified as Neither SC nor HD, 30 % as SC Only, and 21.1 % as Both SC and HD. While we found no significant differences between the three groups on reported number of male partners, anal sex acts, or anal sex acts with serodiscordant partners, the Both SC and HD group reported higher numbers of CAS acts and CAS acts with serodiscordant partners and also had a higher proportion of their anal sex acts without condoms compared to the SC Only group. Our findings support the validity of a three-group classification system of SC/HD severity in differentiating psychosexual and HIV-related sexual risk behavior outcomes in a sample of GBM who report similarly high levels of sexual activity. Notwithstanding the need for sex positive HIV prevention programs, interventions that attempt to help Both SC and HD men deal with distress and address their psychosexual needs specifically may derive HIV prevention benefits.

    Conclusion: The number of intermediate risk factors is significantly associated with the PSA failure-free survival rate after radical prostatectomy in the intermediate-risk group. Patients classified into the intermediate-risk group based on all three intermediate risk factors are less likely to achieve a complete cure through surgery alone.

  6. Voluntary euthanasia: a utilitarian perspective.

    2003-10-01

    Belgium legalised voluntary euthanasia in 2002, thus ending the long isolation of the Netherlands as the only country in which doctors could openly give lethal injections to patients who have requested help in dying. Meanwhile in Oregon, in the United States, doctors may prescribe drugs for terminally ill patients, who can use them to end their life--if they are able to swallow and digest them. But despite President Bush's oft-repeated statements that his philosophy is to 'trust individuals to make the right decisions' and his opposition to 'distant bureaucracies', his administration is doing its best to prevent Oregonians acting in accordance with a law that its voters have twice ratified. The situation regarding voluntary euthanasia around the world is therefore very much in flux. This essay reviews ethical arguments regarding voluntary euthanasia and physician-assisted suicide from a utilitarian perspective. I shall begin by asking why it is normally wrong to kill an innocent person, and whether these reasons apply to aiding a person who, when rational and competent, asks to be killed or given the means to commit suicide. Then I shall consider more specific utilitarian arguments for and against permitting voluntary euthanasia.

    We measured the impact of diet, anthropometry, physical activity and lifestyle variables on rates of hip bone mineral density (BMD) loss in 470 white men and 474 white women aged 67-79 years at recruitment dwelling in the community. The subjects were recruited from a prospective population-based diet and cancer study (EPIC-Norfolk) in Eastern England. Dietary intake was measured at baseline using 7-day food diaries and used to calculate intakes of some 31 nutrients and 22 food groups. Standardised questionnaires were used to collect data on anthropometry, physical activity and lifestyle variables. BMD loss (percent per annum; % p.a.) was measured using dual-energy X-ray absorptiometry performed on two occasions an average of 3 years apart (range 2-5 years). The mean rate of BMD change at the total hip region was -0.17% p.a. (SD 1.3% p.a.) in men and -0.41% p.a. (SD 1.2% p.a.) in women. In both men and women, weight gain protected against (and weight loss promoted) BMD loss ( Pclimbing a flight of stairs, BMD increased at a rate of 0.22% p.a. ( P=0.005) and additionally a 10% increase in activities of daily living score was associated with BMD increasing at a rate of 0.12% p.a. ( P=0.011) in women. Nutritional variation appeared to have less impact on BMD loss. In men there was no evidence of an effect of any of the nutrients evaluated. However, in women, low intake of vitamin C was associated with faster rate of BMD loss. Women in the lowest tertile (7-57 mg/day) of vitamin C intake lost BMD at an average rate of -0.65% p.a., which was significantly faster compared to loss rates in the middle (58-98 mg/day) and upper (99-363 mg/day) tertiles of intake, which were -0.31% p.a. and -0.30% p.a., respectively ( P=0.016). There was no effect of fruits and vegetables, combined or separately, on rate of BMD loss. The results confirm that weight maintenance (or gain) and commonly practiced forms of physical activity appear to protect against BMD loss in this age group

    1997-12-31

    According to this report, voluntary agreements have a potential as instruments for environmental policy. Such agreements can be national or international. Through an international voluntary agreement the authorities in one country may make contracts with factories in another country about emission reductions against some kind of compensation. A supranational organisation of voluntary agreements may ensure equal environmental political conditions for factories in different countries and be a useful means for the regulation of environmental problems of regional or global extent. It is most realistic to establish a supranational system of voluntary agreements in a group of countries that have already institutionalized their relations, such as the European Union. 14 refs., 1 table

  16. Fall risk awareness and safety precautions taken by older community-dwelling women and men--a qualitative study using focus group discussions.

    Directory of Open Access Journals (Sweden)

    Petra Pohl

    Full Text Available Daily life requires frequent estimations of the risk of falling and the ability to avoid a fall. The objective of this study was to explore older women's and men's understanding of fall risk and their experiences with safety precautions taken to prevent falls.A qualitative study with focus group discussions was conducted. Eighteen community-dwelling people [10 women and 8 men] with and without a history of falls were purposively recruited. Participants were divided into two groups, and each group met four times. A participatory and appreciative action and reflection approach was used to guide the discussions. All discussions were audio recorded and transcribed verbatim. Data were analysed by qualitative content analysis, and categories were determined inductively.Three categories describing the process of becoming aware of fall risks in everyday life were identified: 1] Facing various feelings, 2] Recognizing one's fall risk, and 3] Taking precautions. Each category comprised several subcategories. The comprehensive theme derived from the categories was "Safety precautions through fall risk awareness". Three strategies of ignoring [continuing a risky activity], gaining insight [realizing the danger in a certain situation], and anticipating [thinking ahead and acting in advance] were related to all choices of actions and could fluctuate in the same person in different contexts.The fall risk awareness process might be initiated for various reasons and can involve different feelings and precautions as well as different strategies. This finding highlights that there are many possible channels to reach older people with information about fall risk and fall prevention, including the media and their peers. The findings offer a deeper understanding of older peoples' conceptualizations about fall risk awareness and make an important contribution to the development and implementation of fall prevention programmes.

    Maximal voluntary isometric contraction (MVIC) is becoming widely used for monitoring disease progression in amyotrophic lateral sclerosis (ALS). We evaluated the variability of MVIC in a large multicenter (29 sites) drug trial in ALS. Intra- and interrater variability were assessed twice during the 19-month study. Intrarater reliability increased from the first to the second test, approaching the reliability reported for a single experienced clinical evaluator, but interrater reliability did not. Multiple clinical evaluators in a single site increased the variability of MVIC measurements. Rigorous quality assurance standards and monitoring of clinical evaluators should be incorporated into the design of multicenter studies using MVIC, since low variability is necessary to detect a modest treatment effect.

    2003-08-01

    The purpose of this investigation was to assess whether mental practice facilitates the development of voluntary control over the recruitment of the abductor hallucis muscle to produce isolated big toe abduction. A sample of convenience of 15 women and 20 men with a mean age of 28.8 yr. (SD=5.7) and healthy feet, who were unable voluntarily to abduct the big toe, were randomly assigned to one of three groups, a mental practice group, a physical practice group, and a group who performed a control movement during practice. Each subject received neuromuscular electrical stimulation to introduce the desired movement prior to each of five practice bouts over a single session lasting 2 hr. Big toe abduction active range of motion and surface electromyographic (EMG) output of the abductor hallucis and extensor digitorum brevis muscles were measured prior to the first practice bout and following each practice bout, yielding seven acquisition trials. Acquisition is defined as an improvement in both active range of motion and in the difference between the integrated EMG of the abductor hallucis and extensor digitorum brevis muscles during successive acquisition trials. Seven members of both the mental and physical practice groups and one member of the control group met the acquisition criteria. Chi-square analysis indicated the group difference was statistically significant, suggesting mental practice was effective for this task.

    This study compared the extent of twitch and M-wave potentiation (POT) between voluntary and stimulated quadriceps contractions performed at the same intensity. Sixteen healthy men completed 10-s isometric knee extensions at 40% of the maximal voluntary contraction torque under electrical stimulation and voluntary conditions. Single stimuli were delivered to the femoral nerve to evoke twitches before (PRE) and from 3 to 600 s after the end of each conditioning contraction. Changes in twitch contractile properties and M-wave characteristics were compared between the conditions. The extent of twitch peak torque POT was smaller for the stimulated (122+/-20% of PRE) than for the voluntary condition (133+/-20% of PRE). The magnitude of POT for the maximal rate of twitch torque development was also smaller for the stimulated trial. Rectus femoris M-wave amplitude was potentiated by the voluntary but not by the stimulated contraction. It was concluded that stimulated contractions resulted in smaller twitch and M-wave POT than voluntary contractions, despite equivalent torque output and duration. The spatially and temporally fixed recruitment of motor units with electrical stimulation and therefore the lower number of activated motor units compared with voluntary actions of equal intensity could explain the present findings.

    2012-06-01

    This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.

    Quercetin supplementation increases muscle oxidative capacity and endurance in mice, but its ergogenic effect in humans has not been established. Our study investigates the effects of short-duration chronic quercetin supplementation on muscle oxidative capacity; metabolic, perceptual, and neuromuscular determinants of performance in prolonged exercise; and cycling performance in untrained men. Using a double-blind, pretest-posttest control group design, 30 recreationally active, but not endurance-trained, young men were randomly assigned to quercetin and placebo groups. A noninvasive measure of muscle oxidative capacity (phosphocreatine recovery rate using magnetic resonance spectroscopy), peak oxygen uptake (Vo(2peak)), metabolic and perceptual responses to submaximal exercise, work performed on a 10-min maximal-effort cycling test following the submaximal cycling, and voluntary and electrically evoked strength loss following cycling were measured before and after 7-16 days of supplementation with 1 g/day of quercetin in a sports hydration beverage or a placebo beverage. Pretreatment-to-posttreatment changes in phosphocreatine recovery time constant, Vo(2peak,) substrate utilization, and perception of effort during submaximal exercise, total work done during the 10-min maximal effort cycling trial, and voluntary and electrically evoked strength loss were not significantly different (P > 0.05) in the quercetin and placebo groups. Short duration, chronic dietary quercetin supplementation in untrained men does not improve muscle oxidative capacity; metabolic, neuromuscular and perceptual determinants of performance in prolonged exercise; or cycling performance. The null findings indicate that metabolic and physical performance consequences of quercetin supplementation observed in mice should not be generalized to humans.

  4. Syndemic production and sexual compulsivity/hypersexuality in highly sexually active gay and bisexual men: further evidence for a three group conceptualization.

    Among gay and bisexual men (GBM), a syndemic describes a situation in which negative conditions (e.g., childhood sexual abuse, intimate partner violence, depression, polysubstance use) co-occur such to amplify HIV risk. Research has suggested that sexual compulsivity (SC) may also be a syndemic condition. Between 2011 and 2013, 368 highly sexually active (9+ male partners in 90 days) GBM completed a survey of syndemic factors as well as measures of sexual compulsivity (Sexual Compulsivity Scale [SCS]) and hypersexuality (hypersexual disorder screening inventory [HDSI]). Based on scores on the SCS and HDSI, participants were organized into three groups-negative on both ("Neither SC nor HD"); positive on the SCS only ("SC Only"), and positive on both the SCS and the HDSI ("Both SC and HD"). We found support for the utility of a three-group classification of sexual compulsivity/hypersexuality as one of the syndemic factors that contribute to HIV risk. The average number of syndemic factors experienced was lowest among those who experienced Neither SC nor HD and highest among the group that experienced Both SC and HD, with those experiencing SC Only falling between the two other groups. This study provided further evidence that sexual compulsivity/hypersexuality is a contributing factor to the syndemics model of HIV risk for GBM and that considering three levels of severity (i.e., SC along with HD) led to stronger model predictions than considering SC alone. SC/HD severity provides another modifiable target for HIV prevention intervention development.

    Armodafinil (Nuvigil(®), Cephalon, Inc., Frazer, PA, USA), the longer-lasting isomer of racemic modafinil, is a nonamphetamine, wakefulness-promoting medication. In patients with excessive sleepiness associated with shift work disorder, treated obstructive sleep apnoea, or narcolepsy, armodafinil has been found to improve wakefulness throughout the shift or day. In addition, while not approved for this indication, armodafinil has been found to improve excessive sleepiness associated with jet-lag disorder. This study evaluated systemic exposure to armodafinil and its two major circulating metabolites, R-modafinil acid and modafinil sulfone, and assessed the tolerability profile of armodafinil in elderly and young subjects. The pharmacokinetics and tolerability of armodafinil were assessed in an open-label, multiple-dose, parallel-group study in two groups (n = 25 in each group) of healthy men (elderly group aged ≥65 years and young group aged 18-45 years) who received armodafinil 50 mg on day 1, 100 mg on day 2 and 150 mg once daily on days 3 through 7. Plasma concentrations of armodafinil and its metabolites were quantified over 72 hours following the last dose on day 7. Pharmacokinetic parameters, including area under the plasma drug concentration-versus-time curve during a dosing interval (AUC(τ)) and maximum observed plasma drug concentration (C(max)), and tolerability were assessed. All 50 subjects enrolled in the study were evaluable for tolerability and 49 were included in the pharmacokinetic analysis. One elderly subject was excluded from the pharmacokinetic analyses because of apparent noncompliance with armodafinil dosing. Systemic exposure following administration of armodafinil, as measured by steady-state AUC(τ) and C(max) values, was approximately 15% greater in elderly subjects compared with young subjects. Geometric mean ratios for AUC(τ) and C(max) in the two groups were 1.14 (95% CI 1.03, 1.25; p = 0.0086) and 1.15 (95% CI 1

  7. Who Do Batswana Men Prefer: Male or Female Health Providers?

    Letshwenyo-Maruatona, Sandra

    2015-12-14

    Sexual and reproductive health (SRH) services are rarely designed specifically to meet men's needs. There is a general consensus among clinicians that males need access to SRH services. Studies have reported that men are often hesitant to go to health facilities because they feel uncomfortable being served by female providers. The study sought to determine whether men who participate in SRH services have specific preference for the gender of health workers for consultation on different types of services. A mixed-method design was employed. A combination of stratified proportional sampling of facilities and criterion purposive sampling of participants were used. Questionnaires were used to collect data from 390 participants, which were complemented with 10 in-depth interviews. Chi-square analysis with post hoc comparisons were used to determine whether there were significant differences in gender preference for specific services. Based on the data, Batswana males did not have any gender preference of the health provider for consultation on SRH services. The gender of the provider is of minor importance compared with other characteristics such as competence and confidentiality. However, the gender of the provider seems to be more important to younger men for delivery, sexually transmitted infections, voluntary counselling, and testing services. Further research is needed because the study was conducted in the city and the participants' characteristics may be unique to an urban setting. Preferences for providers among demographic groups can be useful in informing resource prioritization and help direct program efforts to reach different subgroups of males.

  10. Dynamics of Voluntary Cough Maneuvers

    Science.gov (United States)

    Naire, Shailesh

    2008-11-01

    Voluntary cough maneuvers are characterized by transient peak expiratory flows (PEF) exceeding the maximum expiratory flow-volume (MEFV) curve. In some cases, these flows can be well in excess of the MEFV, generally referred to as supramaximal flows. Understanding the flow-structure interaction involved in these maneuvers is the main goal of this work. We present a simple theoretical model for investigating the dynamics of voluntary cough and forced expiratory maneuvers. The core modeling idea is based on a 1-D model of high Reynolds number flow through flexible-walled tubes. The model incorporates key ingredients involved in these maneuvers: the expiratory effort generated by the abdominal and expiratory muscles, the glottis and the flexibility and compliance of the lung airways. Variations in these allow investigation of the expiratory flows generated by a variety of single cough maneuvers. The model successfully reproduces PEF which is shown to depend on the cough generation protocol, the glottis reopening time and the compliance of the airways. The particular highlight is in simulating supramaximal PEF for very compliant tubes. The flow-structure interaction mechanisms behind these are discussed. The wave speed theory of flow limitation is used to characterize the PEF. Existing hypotheses of the origin of PEF, from cough and forced expiration experiments, are also tested using this model.

    With fatiguing exercise, firing of group III/IV muscle afferents reduces voluntary activation and force of the exercised muscles. These afferents can also act across agonist/antagonist pairs, reducing voluntary activation and force in nonfatigued muscles. We hypothesized that maintained firing of group III/IV muscle afferents after a fatiguing adductor pollicis (AP) contraction would decrease voluntary activation and force of AP and ipsilateral elbow flexors. In two experiments (n = 10) we examined voluntary activation of AP and elbow flexors by measuring changes in superimposed twitches evoked by ulnar nerve stimulation and transcranial magnetic stimulation of the motor cortex, respectively. Inflation of a sphygmomanometer cuff after a 2-min AP maximal voluntary contraction (MVC) blocked circulation of the hand for 2 min and maintained firing of group III/IV muscle afferents. After a 2-min AP MVC, maximal AP voluntary activation was lower with than without ischemia (56.2 ± 17.7% vs. 76.3 ± 14.6%; mean ± SD; P muscle afferents from the hand decreased voluntary drive and force of AP. Moreover, this effect decreased voluntary drive and torque of proximal unfatigued muscles, the elbow flexors. Fatigue-sensitive group III/IV muscle nociceptors act to limit voluntary drive not only to fatigued muscles but also to unfatigued muscles within the same limb.

    In India, increasing uptake of voluntary HIV testing among 'core risk groups' is a national public health priority. While HIV testing uptake has been studied among key populations in India, limited information is available on multi-level barriers and facilitators to HIV testing, and experiences with free, publicly available testing services, among key populations. We conducted 12 focus groups (n = 84) and 12 key informant interviews to explore these topics among men who have sex with men, transgender women, cisgender female sex workers, and injecting drug users in the city of Chennai. We identified inter-related barriers at social-structural, health-care system, interpersonal, and individual levels. Barriers included HIV stigma, marginalised-group stigma, discrimination in health-care settings, including government testing centres, and fears of adverse social consequences of testing HIV positive. Facilitators included outreach programmes operated by community-based/non-governmental organisations, accurate HIV knowledge and risk perception for HIV, and access to drug dependence treatment for injecting drug users. Promoting HIV testing among these key populations requires interventions at several levels: reducing HIV-related and marginalised-group stigma, addressing the fears of consequences of testing, promoting pro-testing peer and social norms, providing options for rapid and non-blood-based HIV tests, and ensuring non-judgmental and culturally competent HIV counselling and testing services.

    Body adiposity index (BAI), based on height and hip circumference data from Mexican-Americans and African-Americans established its relation to body fat (BF). The aim of our study was to compare body mass index (BMI) and BAI in relation to BF%. Participants were adult men of three endogamous social groups (Brahmin, Muslim and Namasudra) in a village of South 24 Parganas district in West Bengal, India. Height, weight and hip circumference of 952 individuals (370 Brahmins, 307 Muslims and 275 Namasudras) were recorded. The BMI-based nutritional status and bioelectrical impedance-based BF% were evaluated. Namasudras (33.8%) and Muslims (33.6%) had high frequency undernutrition compared to Brahmins (7.3%). High prevalence (46.22%) of excess weight (overweight+obesity) was recorded only among Brahmins. There was significant social group difference in rates of nutritional status (χ(2) = 93.10, p BMI than BAI. A cut-off value of BAI (22%) was determined by binomial logistic regression analysis (BLRA). The value had best estimated relation to BF% and also coincided with WHO standard mean BF (22%) for overweight adults at BMI (≥ 25 kg/m(2)). However, greater area under the receiver operating characteristic curve, higher correct prediction rate, and other results of BLRA for the cut-off value of BMI-based overweight (≥ 25 kg/m(2)) showed its better relation to BF% than that observed for BAI cut-off at 22%. The BMI was observed to be a better indicator of adiposity compared to BAI in relation with body fat (%). Copyright © 2014 Elsevier GmbH. All rights reserved.

    Human adult aging is associated with a loss of strength, contractile velocity and hence, power. The principal plantar flexors, consisting of the bi-articular gastrocnemeii and the mono-articular soleus, appear to be affected differently by the aging process. However, the age-related effect of knee joint angle on the torque-angular velocity relationship and power production of this functionally important muscle group is unknown. The purpose was to determine whether flexing the knee, thereby reducing the gastrocnemius contribution to plantar flexion, would exacerbate the age-related decrements in plantar flexion power, or shift the torque-angular velocity relationship differently in older compared with young men. Neuromuscular properties were recorded from 10 young (~25 y) and 10 old (~78 y) men with the knee extended (170°) and flexed (90°), in a randomized order. Participants performed maximal voluntary isometric contractions (MVCs), followed by maximal velocity-dependent shortening contractions at pre-set loads, ranging from 15 to 75% MVC. The young men were ~20-25% stronger, ~12% faster and ~30% more powerful than the old for both knee angles (Ptorque was ~17% greater in the extended than flexed knee position, with no differences in voluntary activation (>95%). The young men produced 7-12% faster angular velocities in the extended knee position for loads ≤30% MVC, but no differences at higher loads; whereas there were no detectable differences in angular velocity between knee positions in the old across all relative loads. For both knee angles, young men produced peak power at 43.3±9.0% MVC, whereas the old men produced peak power at 54.8±7.9% MVC. These data indicate that the young, who have faster contracting muscles compared with the old, can rely more on velocity than torque for generating maximal power.

    Worldwide suicide is a deeply gendered phenomenon. In South Africa, approximately 80% of suicide completers are male. This study aimed to investigate how a group of young South African men understand and think about suicidal behavior. In-depth semistructured interviews and thematic analysis using a grounded theory approach revealed that this group of young South African men had permissive attitudes to suicide and viewed suicide as a morally defensible alternative in specific situations. They spoke of suicide as a goal-directed behavior that provides a means of regaining control, asserting power, communicating, and rendering oneself visible. From this perspective, suicide was understood as a brave act requiring strength and determination. These data have congruence with the Theory of Gender and Health, which proposes that constructions of masculinity may be implicated in the attitudes and beliefs young men in South Africa hold toward suicide.

    In the absence of large, prospective, placebo-controlled studies of longer duration, substantial evidence regarding the safety and risk of testosterone (T) therapy (TTh) with regard to cardiovascular (CV) outcomes can only be gleaned from observational studies. To date, there are limited studies comparing the effects of long-term TTh in men with hypogonadism who were treated or remained untreated with T, for obvious reasons. We have established a registry to assess the long-term effectiveness and safety of T in men in a urological setting. Here, we sought to compare the effects of T on a host of parameters considered to contribute to CV risk in treated and untreated men with hypogonadism (control group). Observational, prospective, cumulative registry study in 656 men (age: 60.7 ± 7.2 years) with total T levels ≤12.1 nmol/L and symptoms of hypogonadism. In the treatment group, men (n = 360) received parenteral T undecanoate (TU) 1000 mg/12 weeks following an initial 6-week interval for up to 10 years. Men (n = 296) who had opted against TTh served as controls. Median follow-up in both groups was 7 years. Measurements were taken at least twice a year, and 8-year data were analyzed. Mean changes over time between the 2 groups were compared by means of a mixed-effects model for repeated measures, with a random effect for intercept and fixed effects for time, group, and their interaction. To account for baseline differences between the 2 groups, changes were adjusted for age, weight, waist circumference, fasting glucose, blood pressure, and lipids. There were 2 deaths in the T-treated group, none was related to CV events. There were 21 deaths in the untreated (control) group, 19 of which were related to CV events. The incidence of death in 10 patient-years was 0.1145 in the control group (95% confidence interval [CI]: 0.0746-0.1756; P control group and none in the T-treated group. Long-term TU was well tolerated with excellent adherence suggesting a high level of

    Independent clinical factors predicting reinfarction in the 1st year following an initial myocardial infarction were identified among 900 women and 2,795 men. Women were older (65.8 vs. 59.3 years; p men (6.9 vs. 5.6%, p = 0.17). Cumulative 1-month, 1- and 5.5-year all-cause mortality following the first infarction was higher among women who sustained reinfarction (43, 52 and 74%, respectively) than among men (29, 30 and 51%, respectively, p women were (adjusted relative odds): peripheral vascular disease (3.2), postinfarction angina (2.3), diabetes mellitus (2.2), radiographic evidence of cardiomegaly (1.9), anterior location of the first infarction (2.0), congestive heart failure (1.8), prior angina (1.6) and age (10 years) increment (1.2). Predictive variables for men were: anterior infarct location (1.7), peripheral vascular disease (1.6, prior stroke (1.5), prior angina (1.4), systemic hypertension (1.3) and age (10 years) increment (1.1). Our data indicate (a) different cardiac risk factors for reinfarction among men and women after a first myocardial infarction, and (b) a prognostic advantage for men over women following reinfarction.

  5. To have sex or not to have sex? An online focus group study of sexual decision making among sexually experienced and inexperienced gay and bisexual adolescent men.

    Adolescent gay and bisexual men (AGBM) are at disproportionately high risk for HIV and other sexually transmitted infections, yet healthy sexuality and HIV prevention programs grounded in experiences unique to AGBM (e.g., coming out) are lacking, as is the formative work necessary to inform such programs. A richer understanding of factors informing AGBM's decisions to have or not have sex is needed. To fill this gap in the literature, we conducted qualitative and mixed-methods analyses of data collected in online focus groups with 75 ethnically diverse 14-18-year-old AGBM across the United States. Findings suggest that many reasons why AGBM choose to have or abstain from sex mirror those noted in the previous literature as influential for heterosexual adolescents (e.g., temptation, "horniness"). AGBM conveyed additional experiences/concerns that appeared unique to their sexual identity, particularly fears about pain during anal sex, and difficulties safely and accurately identifying same-sex partners. Both sexually experienced and inexperienced youth voiced reasons to wait or stop having sex. Sexually inexperienced youth said their motivations centered on wanting to avoid STIs and HIV, a desire to wait for the right partner, and the specialness of sex. On the other hand, sexually experienced AGBM said they stopped having sex if there was not an available partner they had interest in, or to improve their romantic relationship. Thus, while our findings suggest that there may be common factors across sexual identities that impact youth's sexual decision making, healthy sexuality programs for AGBM also need to address issues specific to being gay and bisexual.

    1993-11-01

    A prospective study of patients undergoing coronary artery bypass graft surgery (CABG) was conducted to examine differences in hospital mortality by sex. Outcome data on 3055 CABG patients undergoing operation between 1987 and 1989 were examined for differences in patient, disease, and treatment factors. Odds ratios (OR), risk differences, and 95% confidence intervals (CI95%) were calculated. Mortality rates for women (7.1%) and men (3.3%) differed, the OR (women versus men) being 2.23 (CI95%, 1.58 to 3.15). Women were older, more often diabetic, and had more urgent or emergent surgery; adjustment yielded an OR (women versus men) of 1.75 (CI95%, 1.17 to 2.63). Body surface area (BSA) was associated with risk of death in both sexes (P = .007) and positively associated with coronary artery luminal diameters. After adjustment for BSA, sex was no longer significantly associated with mortality (OR [women versus men] of 1.18; CI95%, 0.72 to 1.95). Internal mammary artery (IMA) grafting was performed less frequently among women than men (64.8% versus 78.4%, P < .001). Smaller BSA and absence of IMA grafting were each associated with increased risk of death (RD) from heart failure. Risk of death from heart failure (RD [women minus men] = 2.05; CI95%, 0.89 to 3.22) and hemorrhage (RD [women minus men] = 0.63; CI95%, 0.13 to 1.13) was greater among women; these accounted for 71.1% of the sex-specific difference in mortality rates. Excess risk of hospital mortality among women having CABG was largely the consequence of death from heart failure and, to a lesser extent, from hemorrhage. Smaller BSA (probably because of its association with coronary artery luminal diameter) and the absence of IMA grafting were each associated with increased risk of death from heart failure.

    The aim of the current study was to examine demographic and contextual correlates of voluntariness in parents making research or treatment decisions for their children with cancer. Participants included 184 parents of children with cancer who made a decision about enrolling the child in a research or treatment protocol within the previous 10 days. Parents completed questionnaires that assessed voluntariness, external influence by others, concern that the child's care would be negatively affected if the parent did not agree, time pressure, information adequacy, and demographics. Lower perceived voluntariness was associated with lower education, male gender, minority status, and not having previous experience with a similar decision. Parents who reported lower voluntariness also perceived more external influence and time pressure, had more concern about the child's care being negatively affected if they declined, and perceived that they had either too much or not enough information about the decision. In a multivariate regression, education, minority status, gender, external influence, and too little information remained significantly associated with voluntariness. Several groups of parents appear to be at risk for decreased voluntariness when making research or treatment decisions for their seriously ill children, including fathers, nonwhite parents, and those with less education. Parental voluntariness may be enhanced by helping parents to mitigate the effects of unhelpful or unwanted influences by others and ensuring that their information needs are met.

    of the study was to investigate blood levels of proprotein convertase subtilisin/kexin type 9 (PCSK9) in men from different population subgroups, their associations with cardiovascular risk factors and with unfavorable 7-years long-term prognosis. The study included three subgroups of men from a population sample of residents of Novosibirsk, 44-73 years old, not receiving lipid-lowering drugs: subgroup of population proper (183 men), subgroup with hypercholesterolemia (46 men), and subgroup with hypocholesterolemia (18 men). Blood level of PCSK9 was determined by ELISA using the test-systems "Human Proprotein Convertase 9/PCSK9 Immunoassay". Study endpoints (myocardial infarction, cardiovascular death) were registered during 7 years after baseline examination of subgroups using the data of the Registers of myocardial infarction and cardiovascular mortality. Distribution of PCSK9 protein in subgroups with hyper- and hypocholesterolemia was normal. In the subgroup of population proper it was abnormal with leftward shift. PCSK9 protein concentration in the subgroup with hypercholesterolemia was 1.2 times higher than in the population subgroup. PCSK9 protein level correlated significantly with blood levels of total cholesterol (CH), low density lipoprotein (LDL) CH, and glucose. Only 15% of PCSK9 variability was due to the influence of other factors (R Square=0.155, p<0.001). Factors with significant influence on blood level of PCSK9 protein were levels of high density lipoprotein CH (=0.238, p=0.023), triglycerides (=0.253, p=0.049) and LDL CH (=0.751, p=0.009). Multivariate regression analysis revealed significant independent association of PCSK9 protein levels with cardiovascular death during period of registration (7-years) (p=0.048, OR=1.01). This result indicates that in men increase of blood level of PCSK9 protein by 1ng/ml independently of other parameters increases relative risk of cardiovascular death during following 7 years by 1%.

    Objective To determine the feasibility and the effectiveness of HIV risk behavior intervention characterized by initiator taking the lead combined with peer's participation,as to preventing HIV epidemic through promoting condom use and reducing the number of sexual partners among men who have sex with men(MSM)groups. Methods Subjects were recruited via peer referral chain. Twelve key MSM were recruited as initiators in bars or other MSM venues in 3 cities of Hefei,Wuhu and Fuyang. Then,each initiator recruited up to 3 MSM to participate and also each of them continued recruiting others. A total of 218 eligible MSM were recruited,and there were four intervention activities conducted. Firstly,twelve initiators were trained according to intervention manual and then intervention activities were implemented by initiators based on their referral chain. Participants were required to complete self-administrated questionnaire at baseline and the third month after intervention finished. The comparison of the results before and after intervention was conducted two months later to see any improvement in HIV/AIDS knowledge,and condom use. Results Of 218 participants,170(77.9%)were followed up in assessment three months later. The results from paired t-Test and Chi Square Test showed that intervention increased HIV/STDs related knowledge(baseline,14.71±2.59;follow-up,16.95±1.81;t=-10.647,P<0.01)and the rate of having female sexual partner during previous 2 months(baseline,17.6%;follow-up,11.2%;P<0.01)were of significant differences. Meanwhile,the intervention increased rate of condom use in the last three times of anal intercourse with homosexual partners,casual homosexual partners and primary homosexual partners(baseline,55.3%,43.2%,49.1%;follow-up,65.2%,52.2%,60.9%;x2=9.979,P<0.01;x2=5.797,P<0.05;x2=13.082,P<0.01;respectively)and decreased rate of non-condom use in the last anal intercourse with

    Voluntary memory suppression can keep unwanted memories from entering consciousness, inducing later forgetting of the information. In the present study, we searched for the existence of anticipatory processes, mediating such voluntary memory suppression. Using the think/no-think paradigm, subjects received a cue whether to prepare to think of a previously studied cue-target pair or whether to not let a previously studied cue-target pair enter consciousness. Examining event-related potentials, we identified two electrophysiological processes of voluntary memory suppression: (1) an early anticipatory process operating before the memory cue for a to-be-suppressed memory was provided, and (2) a later process operating after memory cue presentation. Both ERP effects were due to a decreased right frontal and left parietal positivity. They were positively related and predicted later forgetting. The results point to the existence of anticipatory processes, mediating voluntary memory suppression.

    Full Text Available The economic importance of voluntary work has been exceedingly appreciated in the last few decades. This is not surprising at all, because it is highly profitable according to the related estimated data. There are 115,9 million people doing voluntary work only in Europe, which means that they would create the world's 7th biggest economy with EUR 282 billion value creation if they formed an individual state. The organizations know that voluntary work has several advantages apart from the economic benefits. It is profitable both for the society and for the individuals as well. Several researches have proven that voluntary work positively influences the development of the personality, because the key-competencies - such as: co-operation, empathy, solidarity, conflict handling, problem solving, etc. - expected in the labor market can be improved.

    Involuntary physical activity induced by the avoidance of electrical shock leads to improved endurance exercise capacity in animals. However, it remains unknown whether voluntary stand-up physical activity (SPA) without forced simulating factors improves endurance exercise capacity in animals. We examined the eff ects of SPA on body weight, cardiac function, and endurance exercise capacity for 12 weeks. Twelve male Sprague-Dawley rats (aged 8 weeks, n=6 per group) were randomly assigned to a control group (CON) or a voluntary SPA group. The rats were induced to perform voluntary SPA (lifting a load equal to their body weight), while the food height (18.0 cm) in cages was increased progressively by 3.5 every 4 weeks until it reached 28.5 cm for 12 weeks. The SPA group showed a lower body weight compared to the CON group, but voluntary SPA did not affect the skeletal muscle and heart weights, food intake, and echocardiography results. Although the SPA group showed higher grip strength, running time, and distance compared to the CON group, the level of irisin, corticosterone, genetic expression of mitochondrial biogenesis, and nuclei numbers were not affected. These findings show that voluntary SPA without any forced stimuli in rats can eff ectively reduce body weight and enhance endurance exercise capacity, suggesting that it may be an important alternative strategy to enhance endurance exercise capacity.

    Full Text Available Volunteering is an activity that develops in a personal, spontaneous, free, without personal benefits. This is offered by individual citizens, individually or through organizations. Aim: The aim of the present study was to investigate the features of personality for health professionals to volunteering. Methodology: The data collection was done by completing a written questionnaire in time and place of participants’ choice. The tools used were: (a Questionnaire of socio-demographic characteristics, (b the Altruism Scale, (c the Narcissistic Personality Inventory and (d the Eysenck Personality Questionnaire. The statistical analysis was performed using the SPSS (18 statistical package. Results: In this study involved 110 doctors and nurses of Sparta General Hospital (overall study sample, 64.2% of the sample were male, 57.3% were married, 37.7% were tertiary education graduates, while 99.1% had the Greek ethnicity. Results showed that the mean value of the Narcissistic Personality Inventory in women was (7.8 while in men was (11.4. At this point Independent Sample t-test showed statistically significant difference to the mean value of the NPI between women and men t = 2.470 p =0.017.

    Background Men who have sex with men (MSM) are at increased risk of exposure to hepatitis B virus (HBV) compared with the general population. This study aims to assess the epidemiological and virological characteristics of HBV infection in a sample of MSM in Brazil, where data are scarce. Methods A cross-sectional study was conducted among MSM in the City of Goiânia, Central Brazil, from March to November 2014, using Respondent-Driven Sampling (RDS). After signing the consent form, participants were interviewed and a blood sample collected. All samples were tested for HBV serological markers and HBV DNA. HBV nucleotide sequence analysis was also performed. Results A total of 522 MSM were recruited in the study. The prevalence of HBV infection (current or past [presence of anti-HBc marker]) was 15.4% (95% CI: 8.7–25.8) and the rate of HBsAg carriers was 0.6% (95% CI: 0.2–1.6). About 40% (95% CI: 32.3–48.8) of the participants had serological evidence of previous HBV vaccination (reactive for isolated anti-HBs). In addition, 44.3% (95% CI: 36.1–52.9) were seronegative for all HBV markers. Age over 25 years old, receptive anal intercourse, previous sex with women, and history of sexually transmitted infections (STIs) were factors associated with HBV infection. HBV DNA was detected only in HBsAg-positive individuals. HBV isolates were classified into genotype A (subgenotypes A1 and A2), and some mutations were identified throughout the genome. Therefore, occult HBV infection was not observed in the study population. Conclusions Public health strategies should be improved for the MSM population in order to prevent HBV and other STIs, as well as to provide appropriate management of patients with active infections.

    Tryptophan, a precursor of important molecules such as serotonin, melatonin and niacin, is an essential amino acid for dogs. In pigs, tryptophan supplementation has been shown to induce a significant increase in food intake. The aim of the present study was to assess whether long-term tryptophan supplementation increases voluntary food intake in dogs and to observe whether this was accompanied by a change in serum ghrelin. In the present study, sixteen adult Beagle dogs were used, with four male and four female dogs fed diets supplemented with tryptophan (1 g/dog per d) during 81 d (Trp) and four male and four female dogs that were not supplemented (control). A voluntary food intake test was performed during 5 d following the supplementation period. The Trp group tended to show a higher food intake during the voluntary food intake test (58.0 (SE 5.37) v. 77.5 (SE 3.65) g/kg metabolic weight per d; P = 0.074). No significant differences were found for serum ghrelin concentrations.

  7. Attitudes, perceptions and potential uptake of male circumcision among older men in Turkana County, Kenya using qualitative methods.

    Kate Macintyre

    Full Text Available BACKGROUND: In many communities, older men (i.e., over 25 years of age have not come forward for Voluntary Medical Male Circumcision (VMMC services. Reasons for low demand among this group of men are not well understood, and may vary across geographic and cultural contexts. This paper examines the facilitators and barriers to VMMC demand in Turkana County, Kenya, with a focus on older men. This is one of the regions targeted by the VMMC program in Kenya because the Turkana ethnic group does not traditionally circumcise, and the rates of HIV and STD transmission are high. METHODS AND FINDINGS: Twenty focus group discussions and 69 in-depth interviews were conducted with circumcised and uncircumcised men and their partners to elicit their attitudes and perceptions toward male circumcision. The interviews were conducted in urban, peri-urban, and rural communities across Turkana. Our results show that barriers to circumcision include stigma associated with VMMC, the perception of low risk for HIV for older men and their "protection by marriage," cultural norms, and a lack of health infrastructure. Facilitators include stigma against not being circumcised (since circumcision is associated with modernity, protection against disease including HIV, and cleanliness. It was also noted that older men should adopt the practice to serve as role models to younger men. CONCLUSIONS: Both men and women were generally supportive of VMMC, but overcoming barriers with appropriate communication messages and high quality services will be challenging. The justification of circumcision being a biomedical procedure for protection against HIV will be the most important message for any communication strategy.

    2001-12-01

    The repeatability of initial values and rate of change of EMG signal mean spectral frequency (MNF), average rectified values (ARV), muscle fiber conduction velocity (CV) and maximal voluntary contraction (MVC) was investigated in the vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles of both legs of nine healthy male subjects during voluntary, isometric contractions sustained for 50 s at 50% MVC. The values of MVC were recorded for both legs three times on each day and for three subsequent days, while the EMG signals have been recorded twice a day for three subsequent days. The degree of repeatability was investigated using the Fisher test based upon the ANalysis Of VAriance (ANOVA), the Standard Error of the Mean (SEM) and the Intraclass Correlation Coefficient (ICC). Data collected showed a high level of repeatability of MVC measurement (normalized SEM from 1.1% to 6.4% of the mean). MNF and ARV initial values also showed a high level of repeatability (ICC>70% for all muscles and legs except right VMO). At 50% MVC level no relevant pattern of fatigue was observed for the VMO and VL muscles, suggesting that other portions of the quadriceps might have contributed to the generated effort. These observations seem to suggest that in the investigation of muscles belonging to a multi-muscular group at submaximal level, the more selective electrically elicited contractions should be preferred to voluntary contractions.

  11. Voluntary attention increases perceived spatial frequency.

    Voluntary covert attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. Involuntary attention increases perceived spatial frequency (Gobell & Carrasco, 2005), but involuntary attention can differ from voluntary attention in its effects on performance in tasks mediated by spatial resolution (Yeshurun, Montagna, & Carrasco, 2008). Therefore, we ask whether voluntary attention affects the subjective appearance of spatial frequency--a fundamental dimension of visual perception underlying spatial resolution. We used a demanding rapid serial visual presentation task to direct voluntary attention and measured perceived spatial frequency at the attended and unattended locations. Attention increased the perceived spatial frequency of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task. In the control experiment, we ruled out response bias as an alternative account by using a lengthened interstimulus interval, which allows observers to disengage attention from the cued location. In contrast to the main experiment, the observers showed neither increased perceived spatial frequency nor improved orientation discrimination at the attended location. Thus, this study establishes that voluntary attention increases perceived spatial frequency. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.

    The Rh system is the major blood group system besides ABO system. Even after proper blood grouping and cross matching there is a possibility of alloimmunization and antibody production in the recipients against the Rh or minor blood group antigens like Kell, MNSs, Duffy etc. Keeping in view the heavy financial burden of complete phenotyping of blood; the determination of only Rh phenotypes can play a major role in preventing alloimmunization and adverse events in multitransfusion cases. To determine the proportion of Rh phenotypes in voluntary blood donors with a view to generate blood bank data for constitution of panel of blood donors for multipurpose utilities. Identification of Rhesus factors (Rh) was done by the antigen antibody agglutination test by the test tube method on 10,133 healthy voluntary donors. The phenotypic frequencies of Rh blood groups in the studied population were D-92.25%, C-87.55%, E-26.55%, c-51.06% and e-98.42%. Thus 'e' was the most common and E was the least common of all the Rh types. Phenotypically DCCee group was the most common phenotype and dccee was least common type. Determination of Rh phenotypes can play a major role in preventing alloimmunization and avoiding adverse events in multitransfusion cases.

    Advocacy has a critical role to play in addressing concerns about access to appropriate mental health care and treatment for African and Caribbean men. To investigate good practice principles and organizational models for mental health advocacy provision for African and Caribbean men. The study consisted of: (i) A systematic literature review. Bibliographic and internet searching was undertaken from 1994 to 2006. The inclusion criteria related to mental health, advocacy provision for African and Caribbean men. (ii) Four focus groups with African and Caribbean men to explore needs for and experiences of mental health advocacy. (iii) An investigation into current advocacy provision through a survey of advocacy provision in England, Wales and Northern Ireland. (iv) Twenty-two qualitative stakeholder interviews to investigate the operation of mental health advocacy for this client group. The study was undertaken in partnership with two service user-led organizations and an African Caribbean mental health service. Primary research in this area is scant. Mainstream mental health advocacy services are often poor at providing appropriate services. Services developed by the Black Community and voluntary sector are grounded in different conceptualizations of advocacy and sharper understanding of the needs of African and Caribbean men. The lack of sustainable funding for these organizations is a major barrier to the development of high-quality advocacy for this group, reflecting a lack of understanding about their distinctive role. The commissioning and provision of mental health advocacy needs to recognize the distinct experiences of African and Caribbean men and develop capacity in the range of organizations to ensure equitable access. © 2011 Blackwell Publishing Ltd.

    Qualitative interviews were conducted with 21 Latino immigrant men who participated in a culturally informed batterer intervention. The objectives of this investigation were twofold. First, to identify the treatment components that facilitated the participants' willingness to engage in a process of change aimed at terminating their abusive behaviors. Second, to describe the treatment components that led to their satisfaction with the intervention. Research findings confirm that the Spanish version of the Duluth curriculum can be beneficial for Latino immigrant batterers. Results also demonstrate the critical role of culture as it refers to content of the intervention and method of delivery.

It is one element in an array of such programs introduced in recent years as part of the effort being made by the United States to comply with its national commitment to stabilize emissions of greenhouse gases under the Framework Convention on Climate Change. The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report to the Energy Information Administration (EIA) on actions taken that have reduced or avoided emissions of greenhouse gases.

    In order to study the effect of the alpha EEG power increasing training at heart rate variability (HRV) as the index of the autonomic regulation of cognitive functions there were follow tasks: (1) to figure out the impact of biofeedback in the voluntary increasing the power in the individual high-frequency alpha-band effect on heart rate variability and related characteristics of cognitive and emotional spheres, (2) to determine the nature of the relationship between alpha activity indices and heart rate variability, depending on the alpha-frequency EEG pattern at rest (3) to examine how the individual alpha frequency EEG pattern is reflected in changes HRV as a result of biofeedback training. Psychometric indicators of cognitive performance, the characteristics of the alpha-EEG activity and heart rate variability (HRV) as LF/HF and pNN50 were recorded in 27 healthy men aged 18-34 years, before, during, and after 10 sessions of training of voluntary increase in alpha power in the individual high-frequency alpha band with eyes closed. To determine the biofeedback effect on the alpha power increasing training, data subjects are compared in 2 groups: experimental (14) with the real and the control group (13 people)--with mock biofeedback. The follow up effect of trainings was studied through month over the 10 training sessions. Results showed that alpha biofeedback training enhanced the fluency and accuracy in cognitive performance, decreased anxiety and frontal EMG, increased resting frequency, width and power in individual upper alpha range only in participants with low baseline alpha frequency. While mock biofeedback increased resting alpha power only in participants with high baseline resting alpha frequency and did change neither cognitive performance, nor HRV indices. Biofeedback training eliminated the alpha power decrease in response to arithmetic task in both with high and low alpha frequency participants and this effect was followed up over the month. Mock

    Full Text Available Voluntary Medical Male Circumcision (VMMC for HIV prevention in Tanzania was introduced by the Ministry of Health and Social Welfare in 2010 as part of the national HIV prevention strategy. A qualitative study was conducted prior to a cluster randomized trial which tested effective strategies to increase VMMC up take among men aged ≥20 years. During the formative qualitative study, we conducted in-depth interviews with circumcised males (n = 14, uncircumcised males (n = 16, and participatory group discussions (n = 20 with men and women aged 20-49 years in Njombe and Tabora regions of Tanzania. Participants reported that mothers and female partners have an important influence on men's decisions to seek VMMC both directly by denying sex, and indirectly through discussion, advice and providing information on VMMC to uncircumcised partners and sons. Our findings suggest that in Tanzania and potentially other settings, an expanded role for women in VMMC communication strategies could increase adult male uptake of VMMC services.

    Many studies have shown that the direction of gaze of a face covertly facilitates the response to a target presented in the matching direction. In this study we seek to determine whether there exist separate reflexive and voluntary forms of such covert social orienting and how they interact with each other. We measured the effect of the predictive value of a gaze cue on manual choice reaction times. When the predictive value of the gaze cue was zero, a facilitatory cueing effect was still observed which peaked at a cue onset to target onset delay (CTD) of 150ms and largely diminished beyond a CTD of 500ms. When the gaze cue was 100% predictive of the future location of the target, at CTDs greater than 200, the predictive cue resulted in a significantly greater facilitation of response than occurred with a non-predictive cue. These results suggest that given enough time (about 200ms), the social cue is interpreted and a willful or voluntary spatially-specific social cueing effect occurs. In addition, we found that a predictive cue resulted in a significant slowing of the observer's responses up to a CTD of 200ms. These findings show that, similar to non-social spatial orienting, there appear to be two forms of social orienting including a reflexive component and voluntary component. We suggest a model of social orienting in which the voluntary social orienting system modulates tonic inhibition of the reflexive social orienting system. Published by Elsevier Ltd.

  17. Does growth hormone therapy in conjunction with resistance exercise increase muscle force production and muscle mass in men and women aged 60 years or older?

    1999-01-01

    Improved muscle protein mass and increments in maximum voluntary muscle force have rarely been observed in men and women aged 60 years and older who were treated with rhGH. Although rhGH administration has been reported to increase lean body mass in older men and women, it is doubtful that this increase is localized to skeletal muscle contractile proteins. When rhGH administration was combined with 16 weeks of resistance exercises, increases in muscle mass, muscle protein synthesis, and muscle force were not greater in the rhGH-treated group than in a weight training group that received placebo injections. Side effects of rhGH treatment in elderly people are prevalent, not trivial, and further limit its usefulness as an effective anabolic agent for promoting muscle protein accretion in men and women. In particular, the induction of insulin resistance and carpal tunnel compression reduces the efficacy of rhGH replacement therapy in elderly individuals. The evidence for a GH-induced increase in human skeletal muscle protein and maximum voluntary muscle force is weak. The optimum dose and GH-replacement paradigm (GHRH, GH-secretagogues) have not been identified. Whether rhGH therapy improves muscle protein mass and force in individuals with severe cachexia associated with major trauma, burns, surgery, or muscular dystrophy is controversial and under investigation.

    In 2007, the World Health Organization endorsed voluntary medical male circumcision (VMMC) as part of comprehensive HIV-prevention strategies. A major challenge facing VMMC programs in sub-Saharan Africa remains demand creation; there is urgent need for data on key elements needed to trigger the decision among eligible men to seek VMMC. Using qualitative methods, we sought to better understand the circumcision decision-making process in Botswana related to VMMC. From July to November 2013, we conducted 27 focus group discussions in four purposively selected communities in Botswana with men (stratified by circumcision status and age), women (stratified by age) and community leaders. All discussions were facilitated by a trained same-sex interviewer, audio recorded, transcribed and translated to English, and analyzed for key themes using an inductive content analytic approach. Improved hygiene was frequently cited as a major benefit of circumcision and many participants believed that cleanliness was directly responsible for the protective effect of VMMC on HIV infection. While protection against HIV was frequently noted as a benefit of VMMC, the data indicate that increased sexual pleasure and perceived attractiveness, not fear of HIV infection, was an underlying reason why men sought VMMC. Data from this qualitative study suggest that more immediate benefits of VMMC, such as improved hygiene and sexual pleasure, play a larger role in the circumcision decision compared with protection from potential HIV infection. These findings have immediate implications for targeted demand creation and mobilization activities for increasing uptake of VMMC among adult men in Botswana.

    During fatiguing upper limb exercise, maintained firing of group III/IV muscle afferents can limit voluntary drive to muscles within the same limb. It is not known if this effect occurs in the lower limb. We investigated the effects of group III/IV muscle afferent firing from fatigued ipsilateral and contralateral extensor muscles and ipsilateral flexor muscles of the knee on voluntary activation of the knee extensors. In three experiments, we examined voluntary activation of the knee extensors by measuring changes in superimposed twitches evoked by femoral nerve stimulation. Subjects attended on 2 days for each experiment. On one day a sphygmomanometer cuff occluded blood flow of the fatigued muscles to maintain firing of group III/IV muscle afferents. After a 2-min extensor contraction (experiment 1; n = 9), mean voluntary activation was lower with than without maintained ischemia (47 ± 19% vs. 87 ± 8%, respectively; P contraction (MVC) (experiment 2; n = 8), mean voluntary activation was also lower with than without ischemia (59 ± 21% vs. 79 ± 9%; P muscle afferents reduces voluntary activation of the fatigued muscle and nonfatigued antagonist muscles in the same leg. However, group III/IV muscle afferents from the fatigued left leg had no effect on the unfatigued right leg. This suggests that any "crossover" of central fatigue in the lower limbs is not mediated by group III/IV muscle afferents.

    Here, we compared motor evoked potentials (MEP) in response to transcranial magnetic stimulation of the motor cortex and the H-reflex during voluntary and vibration-induced air-stepping movements in humans. Both the MEPs (in mm biceps femoris, rectus femoris and tibialis anterior) and H-reflex (in m soleus) were significantly smaller during vibration-induced cyclic leg movements at matched amplitudes of angular motion and muscle activity. These findings highlight differences between voluntary and non-voluntary activation of the spinal pattern generator circuitry in humans, presumably due to an extra facilitatory effect of voluntary control/triggering of stepping on spinal motoneurons and interneurons. The results support the idea of active engagement of supraspinal motor areas in developing central pattern generator-modulating therapies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  4. Moving from voluntary euthanasia to non-voluntary euthanasia: equality and compassion.

    Science.gov (United States)

    Amaraskekara, Kumar; Bagaric, Mirko

    2004-09-01

    The recent Dutch law legalising active voluntary euthanasia will reignite the euthanasia debate. An illuminating method for evaluating the moral status of a practice is to follow the implications of the practice to its logical conclusion. The argument for compassion is one of the central arguments in favour of voluntary active euthanasia. This argument applies perhaps even more forcefully in relation to incompetent patients. If active voluntary euthanasia is legalised, arguments based on compassion and equality will be directed towards legalising active non-voluntary euthanasia in order to make accelerated termination of death available also to the incompetent. The removal of discrimination against the incompetent has the potential to become as potent a catch-cry as the right to die. However, the legalisation of non-voluntary euthanasia is undesirable. A review of the relevant authorities reveals that there is no coherent and workable "best interests" test which can be invoked to decide whether an incompetent patient is better off dead. This provides a strong reason for not stepping onto the slippery path of permitting active voluntary euthanasia.

    Sabarubicin (MEN-10755), a new synthetic anthracycline analogue, was evaluated for safety and efficacy in a multicentre phase II study in patients with advanced hormone refractory prostate cancer (HRPC). Thirty seven patients were included, of which 34 were evaluable for PSA response according to Bubley's criteria. Sabarubicin was administered as a short (30 min) intravenous infusion at a dose of 80 mg/m(2) every 3 weeks. The main toxicity consisted of grade 3/4 neutropenia in 24 patients (64.9%), with grade 3/4 febrile neutropenia occurring in one patient only. Grade 3/4 cardiotoxicity was observed in 4 patients including one ineligible. Other toxicities were mild. Nine patients achieved a PSA response (26.5%), 10 patients had stable disease (29.4%) and 14 patients disease progression (41.2%). One patient (2.9%) had a PSA response that was not confirmed by repeat PSA testing. The objective response rate according to RECIST criteria was 6.7% in 15 patients with measurable disease. The median duration of PSA responses was relatively long 7.1 months (95% CI 4.9-20.7) as was the median time to treatment progression in patients with stable disease. The median overall survival was 18.7 months (95% CI 9.1-N), comparable to results recently observed in taxotere-containing regimens. To confirm and extend these results, further testing of sabarubicin in larger trials is warranted.

  9. Trainability of muscular activity level during maximal voluntary co-contraction: comparison between bodybuilders and nonathletes.

    Directory of Open Access Journals (Sweden)

    Sumiaki Maeo

    Full Text Available Antagonistic muscle pairs cannot be fully activated simultaneously, even with maximal effort, under conditions of voluntary co-contraction, and their muscular activity levels are always below those during agonist contraction with maximal voluntary effort (MVE. Whether the muscular activity level during the task has trainability remains unclear. The present study examined this issue by comparing the muscular activity level during maximal voluntary co-contraction for highly experienced bodybuilders, who frequently perform voluntary co-contraction in their training programs, with that for untrained individuals (nonathletes. The electromyograms (EMGs of biceps brachii and triceps brachii muscles during maximal voluntary co-contraction of elbow flexors and extensors were recorded in 11 male bodybuilders and 10 nonathletes, and normalized to the values obtained during the MVE of agonist contraction for each of the corresponding muscles (% EMGMVE. The involuntary coactivation level in antagonist muscle during the MVE of agonist contraction was also calculated. In both muscles, % EMGMVE values during the co-contraction task for bodybuilders were significantly higher (P<0.01 than those for nonathletes (biceps brachii: 66±14% in bodybuilders vs. 46±13% in nonathletes, triceps brachii: 74±16% vs. 57±9%. There was a significant positive correlation between a length of bodybuilding experience and muscular activity level during the co-contraction task (r = 0.653, P = 0.03. Involuntary antagonist coactivation level during MVE of agonist contraction was not different between the two groups. The current result indicates that long-term participation in voluntary co-contraction training progressively enhances muscular activity during maximal voluntary co-contraction.

  10. Searching for the majority: algorithms of voluntary control.

    Directory of Open Access Journals (Sweden)

    Jin Fan

    Full Text Available Voluntary control of information processing is crucial to allocate resources and prioritize the processes that are most important under a given situation; the algorithms underlying such control, however, are often not clear. We investigated possible algorithms of control for the performance of the majority function, in which participants searched for and identified one of two alternative categories (left or right pointing arrows as composing the majority in each stimulus set. We manipulated the amount (set size of 1, 3, and 5 and content (ratio of left and right pointing arrows within a set of the inputs to test competing hypotheses regarding mental operations for information processing. Using a novel measure based on computational load, we found that reaction time was best predicted by a grouping search algorithm as compared to alternative algorithms (i.e., exhaustive or self-terminating search. The grouping search algorithm involves sampling and resampling of the inputs before a decision is reached. These findings highlight the importance of investigating the implications of voluntary control via algorithms of mental operations.

    Science.gov (United States)

    Klass, Malgorzata; Baudry, Stéphane; Duchateau, Jacques

    2007-07-01

    It is well established that the loss of muscle mass (i.e. sarcopenia) is the primary factor contributing to the reduction in muscle force with ageing. Based on the observation that force declines at a faster rate than muscle mass, neural alterations are also thought to contribute to muscle weakness by reducing central drive to the agonist muscles and by increasing coactivation of the antagonist muscles. Researchers have attempted to quantify the contribution of impaired voluntary drive to the decline in muscle force using superimposed electrical stimulation during maximal voluntary contractions (MVCs) and by recording surface electromyographic (EMG) activity. Although reduced voluntary activation of agonist muscles and increased coactivation of antagonist muscles during a MVC have been reported with advancing age, such changes are not supported by all studies. These discrepancies may be explained by differences in sensitivity between the methods used to assess voluntary activation, as well as differences between the characteristics of the study population, the muscle group that is tested, and the type of contraction that is performed. The objective of this review is to summarize current knowledge regarding the activation of agonist and antagonist muscles during MVC in elderly and to try to clarify the disparities in literature concerning the influence of a possible deficit in voluntary activation on the maximal force capacity of muscles in elderly adults.

    The purpose of this study was to compare the effects of a bout of high-volume isokinetic resistance exercise (HVP) on lower-body strength and markers of inflammation and muscle damage during recovery between young and middle-aged men. Nineteen recreationally-trained men were classified as either a young adult (YA: 21.8 ± 2.0 y; 90.7 ± 11.6 kg) or middle-aged adult (MA: 47.0 ± 4.4 y; 96.0 ± 21.5 kg) group. The HVP consisted of 8 sets of 10 repetitions, with one minute of rest between each set, performed on an isokinetic dynamometer at 60°·sec. Maximal voluntary isometric contractions (MVIC) and isokinetic peak (PKT) and average (AVGT) torque (measured at 240° and 60°·sec) were assessed at baseline (BL), immediately-post (IP), 120-min (120P), 24-hr (24H) and 48-hr (48H) following HVP. Blood was obtained at BL, IP, 30-min, 60-min, 120-min, 24H and 48H following HVP to assess muscle damage and inflammation. All performance data were analyzed using repeated-measures ANCOVA, while all inflammatory and muscle damage markers were analyzed using a two-way (time x group) repeated-measures ANOVA. Results revealed no between-group differences for PKT, AVGT, or rate of torque development at 200ms (RTD200). No between-group differences in myoglobin, creatine kinase, C-reactive protein, or interleukin-6 were observed. Although baseline differences in muscle performance were observed between YA and MA, no between group differences were noted in performance recovery measures from high-volume isokinetic exercise in recreationally-trained men. These results also indicate that the inflammatory and muscle damage response from high-volume isokinetic exercise is similar between recreationally-trained, young and middle-aged adult men.

    The purpose of this study was to determine whether the loss of muscle strength in the elderly could be explained entirely by a decline in the physiological cross-sectional area (PCSA) of muscle. Isometric force, muscle activation (twitch interpolation), and coactivation (surface electromyograph) were measured during maximal voluntary contractions (MVCs) of the elbow flexors (EFs) and extensors (EEs) in 20 young (23 +/- 3 yr) and 13 older (81 +/- 6 yr) healthy men. PCSA was determined using magnetic resonance imaging, and normalized force (NF) was calculated as the MVC/PCSA ratio. The PCSA was smaller in the old compared with the young men, more so in the EEs (28%) compared with the EFs (19%) (P MVC (approximately 30%) with age was similar in the two muscle groups. Muscle activation was not different between the groups, but coactivation was greater (5%) (P architecture of the triceps brachii muscle. In conclusion, although the decline in PCSA explained the majority of strength loss in the old men, additional factors such as greater coactivation or reduced specific tension also may have contributed to the age-related loss of isometric strength.

    The Voluntary Reporting of Greenhouse Gases Program, required by Section 1605(b) of the Energy Policy Act of 1992, records the results of voluntary measures to reduce, avoid, or sequester greenhouse gas emissions. In 1998, 156 US companies and other organizations reported to the Energy information Administration that, during 1997, they had achieved greenhouse gas emission reductions and carbon sequestration equivalent to 166 million tons of carbon dioxide, or about 2.5% of total US emissions for the year. For the 1,229 emission reduction projects reported, reductions usually were measured by comparing an estimate of actual emissions with an estimate of what emissions would have been had the project not been implemented.

  17. The Political Importance of Voluntary Work.

    Science.gov (United States)

    Kunneman, Harry

    This paper aims to develop a complex articulation of the civic meaningfulness of voluntary work that clarifies its political importance as a countervailing narrative pointing beyond dominant neoliberal and consumptive articulations of a good life. To start with, it sketches a hermeneutic perspective on civic meaningfulness based on the work of Paul Ricoeur. Subsequently, it introduces the ideas of 'ethical complexity', 'epistemological complexity' and 'diapoiesis', building on insights from critical complexity thinking and relational biology. It argues that these notions can provide a bridge between hermeneutic perspectives on meaning and values, on the one hand, and questions of meaning and values on the level of scientific and technological developments and within professional organizations, on the other. Thus a broader, more complex picture emerges of the civic meaningfulness of voluntary work in our times.

    Some important vaccinations are not included in the routine childhood immunization schedule in Japan. Voluntary vaccinations are usually paid as an out-of-pocket expense. Low voluntary vaccination coverage rates and high target disease incidence are assumed to be a consequence of voluntary vaccination. Therefore, this study aimed to explore factors associated with voluntary vaccination patterns in children. We conducted an online survey of 1243 mothers from a registered survey panel who had at least one child 2 months to vaccination mainly correlated positively with annual household income and mothers' positive opinions about voluntary vaccinations, but negatively with number of children. Financial support, especially for low income households and households with more than one child, may motivate parents to vaccinate their children. Communication is also an important issue. More opportunities for education and information about voluntary vaccinations should be provided to mothers without distinguishing between voluntary and routine vaccination.

    Osteoporosis has finally been recognized as an important disorder in men. Men have osteoporotic fractures about 10 years later in life than women. Owing to increasing life expectancy, more fractures are predicted. Important risk factors for men include advancing age, smoking or chronic obstructive pulmonary disease, glucocorticoid therapy, and androgen deprivation therapy for prostate cancer. Other groups at risk for osteoporosis include those with alcohol abuse, men on enzyme-inducing antise...

    To identify risk factors for HIV infection among men who have sex with men (MSM) and to provide a theoretical basis for prevention interventions.Between December 2011 and August 2012,a case-control study was conducted among MSM who underwent voluntary counselling and testing for HIV.Confirmed HIV-positive MSM were included in the case group,and HIV-negative MSM were included in the control group.Information on possible risk factors was collected by a survey questionnaire and a qualitative interview.The results of a conditional logistic regression showed that the following were influencing factors for H IV infection:average monthly income between 2001 and 3000 Yuan (odds ratio (0R)=6.341,95% Cl:1.714-12.544),only sometimes using condoms when having anal sex with men in the last 6 months (0R=7.601,95% CI:1.359-23.083),having HIV-positive sex partners (0R=5.273,95% Cl:1.572-17.691),rectal trauma with bleeding in the last 6 months (0R=2.947,95% CI:1.308-6.638),not using condoms at last sexual encounter (OR=1.278,95% CI:1.012-5.595),engaging in commercial sex (0R=5.925,95% CI:1.923-13.890) and having more than 16 sex partners in the last 6 months (0R=1.175,95% Cl:1.021-1.353).These seven factors were the risk factors of HIV infection (OR> 1).However,having anal sex less than 10 times in the previous 1 month (OR=0.002,95% CI:0.000-0.287) was a protective factor against HIV infection among MSM (OR<1),and insertive (0R=0.116,95% Cl:0.000-0.236) (OR<1) anal intercourse influenced HIV infection.Interventions should be targeted at MSM whose average monthly income is between 2001 and 3000 Yuan,and who engage in commercial sex.In addition,the importance of using condoms at every sexual encounter should be emphasised in health education,as should the treatment of rectal trauma with bleeding.Finally,MSM should decrease the number of sex partners and frequency of anal sex to decrease the rate of HIV infection.

  5. Mitigating greenhouse gas emissions: Voluntary reporting

    1997-10-01

    The Voluntary Reporting Program, developed pursuant to Section 1605(b) of the Energy Policy Act of 1992, permits corporations, government agencies, households, and voluntary organizations to report on their emissions of greenhouse gases, and on actions taken that have reduced or avoided emissions or sequestered carbon, to the Energy Information Administration (EIA). This, the second annual report of the Voluntary Reporting Program, describes information provided by the participating organizations on their aggregate emissions and emissions reductions, as well as their emissions reduction or avoidance projects, through 1995. This information has been compiled into a database that includes reports from 142 organizations and descriptions of 967 projects that either reduced greenhouse gas emissions or sequestered carbon. Fifty-one reporters also provided estimates of emissions, and emissions reductions achieved, for their entire organizations. The projects described actions taken to reduce emissions of carbon dioxide from energy production and use; to reduce methane and nitrous oxide emissions from energy use, waste management, and agricultural processes; to reduce emissions of halocarbons, such as CFCs and their replacements; and to increase carbon sequestration.

    Various factors influence the development of the voluntary 'green' power market--the market in which consumers purchase or produce power from non-polluting, renewable energy sources. These factors include climate policies, renewable portfolio standards (RPS), renewable energy prices, consumers' interest in purchasing green power, and utilities' interest in promoting existing programs and in offering new green options. This report presents estimates of voluntary market demand for green power through 2015 that were made using historical data and three scenarios: low-growth, high-growth, and negative-policy impacts. The resulting forecast projects the total voluntary demand for renewable energy in 2015 to range from 63 million MWh annually in the low case scenario to 157 million MWh annually in the high case scenario, representing an approximately 2.5-fold difference. The negative-policy impacts scenario reflects a market size of 24 million MWh. Several key uncertainties affect the results of this forecast, including uncertainties related to growth assumptions, the impacts that policy may have on the market, the price and competitiveness of renewable generation, and the level of interest that utilities have in offering and promoting green power products.

    The aim of this study is to contribute to the emerging field of quantification of Health Impact Assessment (HIA), by analysing how different relative risks affect the burden of disease for various socio-economic groups (SES). Risk analysis, utilising attributable and impact fraction, raises several methodological considerations. The present study illustrates this by measuring the impact of changed distribution levels of smoking on lung cancer, ischemic heart disease (IHD), chronic obstructive lung disorder (COLD) and stroke for the highest and lowest socio-economic groups measured in disability adjusted life years (DALY). The material is based on relative risks obtained from various international studies, smoking prevalence (SP) data and the number of DALY based on data available for Sweden. The results show that if smoking would have been eliminated (attributable fraction, AF), the inequality between the highest and lowest socio-economic groups may decrease by 75% or increase by 21% depending on the size of the relative risk. Assuming the same smoking prevalence for the lowest socio-economic group as for the highest (impact fraction), then the inequality may decrease by 7-26%. Consequently, the size of the relative risk used may have a significant impact, leading to substantial biases and therefore should be taken into serious consideration in HIA.

    Heart rate (HR) is controlled solely by via cardiac parasympathetic outflow in tetraplegic individuals, who lack supraspinal control of sympathetic outflows and circulating catecholamines but have intact vagal pathways. A high-frequency component (HF; at 0.15-0.40 Hz) of the power spectrum of HR variability and its relative value against total power (HF/Total) were assessed using a wavelet transform to identify cardiac parasympathetic outflow. The relative contribution of cardiac parasympathetic and sympathetic outflows to controlling HR was estimated by comparing the HF/Total-HR relationship between age-matched tetraplegic and normal men. Six tetraplegic men with complete cervical spinal cord injury performed static arm exercise at 35% of the maximal voluntary contraction until exhaustion. Although resting cardiac output and arterial blood pressure were lower in tetraplegic than normal subjects, HR, HF, and HF/Total were not statistically different between the two groups. When tetraplegic subjects developed the same force during exercise as normal subjects, HF and HF/Total decreased to 67-90% of the preexercise control and gradually recovered 1.5 min after exercise. The amount and time course of the changes in HF/Total during and after exercise coincided well between both groups. In contrast, the increase in HR at the start of exercise was blunted in tetraplegic compared with normal subjects, and the HR recovery following exercise was also delayed. It is likely that, although the withdrawal response of cardiac parasympathetic outflow is preserved in tetraplegic subjects, sympathetic decentralization impairs the rapid acceleration of HR at the onset of exercise and the rapid deceleration following exercise.

  10. [Vasectomy and tubal ligation: medicopsychological aspects of voluntary sterilization].

    Science.gov (United States)

    Bourgeois, M

    1982-06-01

    Various psychological aspects of voluntary surgical sterilization are examined. Women's own bodies are protected through sterilization from all the risks of pregnancy, but there is an altruistic element of vasectomy which may be perceived by men either positively or as a sacrifice or mutilition. The greater prevalence of female sterilization thus seems logical. Some psychologists view vasectomy as representing the realization of castration fantasies, but despite occurrence of cases which might seem to legitimate this view, most vasectomized men are married adults who have fathered several children and have otherwise proven their maturity. The status of voluntary sterilization appears to differ in the Third World, where rapid population growth threatens collective survival, and in developed countries whose growth rates are low or negative. Requests for reversal are increasingly frequent as women undergo sterilization at younger ages. Remarriage, a change of mind by the couple, or death of a child are the most frequently cited reasons for reversal requests. Reports of the psychological consequences of sterilization tend to vary in different studies, largely because of differences in the socioeconomic and cultural status of the populations studied and also perhaps because some studies are more superficial than others. In numerous questionnaire surveys mostly done in Anglo-Saxon countries, typically 90-99% of subjects have reported themselves satisfied with the results. The great majority report no regrets, an unchanged or improved marital relationship, and an increase in sexual pleasure. Less heterogeneous samples of persons undergoing sterilization for reasons other than simple contraceptive convenience have sometimes given less positive results. Age, economic status, number of children, marital relationship, educational level, religious and moral convictions, and history of medical or psychological problems can all affect satisfaction with sterilization.

  17. Women's roles in voluntary medical male circumcision in Nyanza Province, Kenya.

    Directory of Open Access Journals (Sweden)

    Michele Lanham

    Full Text Available Women are an important audience for voluntary medical male circumcision (VMMC communication messages so that they know that VMMC provides only partial protection against HIV. They may also be able to influence their male partners to get circumcised and practice other HIV protective measures after VMMC. This study was conducted in two phases of qualitative data collection. Phase 1 used in-depth interviews to explore women's understanding of partial protection and their role in VMMC. Phase 2 built on the findings from the Phase 1, using focus groups to test VMMC communication messages currently used in Nyanza Province and to further explore women's roles in VMMC. Sixty-four sexually active women between the ages of 18 and 35 participated. In Phase 1, all women said they had heard of partial protection, though some were not able to elaborate on what the concept means. When women in Phase 2 were exposed to messages about partial protection, however, participants understood the messages well and were able to identify the main points. In Phases 1 and 2, many participants said that they had discussed VMMC with their partner, and for several, it was a joint decision for the man to go for VMMC. These findings suggest that current VMMC messaging is reaching women, though communications could more effectively target women to increase their ability to communicate about partial HIV protection from VMMC. Also, women seem to be playing an important role in encouraging men to get circumcised, so reaching out to women could be a valuable intervention strategy for increasing VMMC uptake and promoting use of other HIV protective measures after VMMC.

    It is estimated that 5.6% of the Tanzanian population ages 15-49 are infected with HIV, but only 30% of adults have ever had an HIV test. Couples' testing has proven to increase testing coverage and introduce HIV prevention, but barriers include access to testing services and unequal gender dynamics in relationships. Innovative approaches are needed to address barriers to couple's testing and increase uptake of HIV testing. Using qualitative data collection methods, a formative study was conducted to assess the acceptability of a home-based couples counseling and testing (HBCCT) approach. Eligible study participants included married men and women, HIV-infected individuals, health care and home-based care providers, voluntary counseling and testing counselors, and community leaders. A total of 91 individuals participated in focus group discussions (FGDs) and in-depth interviews conducted between September 2009 and January 2010 in rural settings in Northern Tanzania. An HBCCT intervention appears to be broadly acceptable among participants. Benefits of HBCCT were identified in terms of access, confidentiality, and strengthening the relationship. Fears of negative consequences from knowing one's HIV status, including stigma, blame, physical abuse, or divorce, remain a concern and a potential barrier to the successful provision of the intervention. Lessons for implementation highlighted the importance of appointments for home visits, building relationships of confidence and trust between counselors and clients, and assessing and responding to a couple's readiness to undergo HIV testing. HBCCT should addresses HIV stigma, emphasize confidentiality, and improve communication skills for disclosure and decision-making among couples.

    This paper use data from a pilot study to analyse relationships between type of resettlement (voluntary or involuntary) and individuals' everyday feelings, perceptions of risk, health status and control. The data were collected in 1995, within the Joint Study Project 2, i.e., a collaborative research project of the European Union and the Commonwealth of Independent States of Russia, Ukraine and Belarus, 1991/92 - 95/96. The aim of the study was to investigate reactions to change and new life conditions of people who had been resettled due to the Chernobyl accident. Participants from the respective countries included adult individuals sampled from two age groups of less than 45 years and 45 years and older, with approximately the same number of men and women. The questionnaire presented various topics to which responses were indicated on quantitative response scales, as well as in open ended response formats. The results presented here focus on emotional reactions, perceived risk and self-rated health among resettled people. The effects of type of resettlement on emotional reactions, Perceived risk and control are discussed.

    Full Text Available Objectives: This study aimed to examine the effectiveness of an Islamic voluntary fasting intervention to control post-Ramadan weight gain. Methods: This study was conducted between July and November 2011. Two weight loss intervention programmes were developed and implemented among groups of overweight or obese Malay women living in the Malaysian cities of Putrajaya and Seremban: a standard programme promoting control of food intake according to national dietary guidelines (group B and a faith-based programme promoting voluntary fasting in addition to the standard programme (group A. Participants’ dietary practices (i.e., voluntary fasting practices, frequency of fruit/vegetable consumption per week and quantity of carbohydrates/protein consumed per day, body mass index (BMI, blood pressure, fasting blood high-density lipoprotein cholesterol (HDL-C and total cholesterol (TC:HDL-C ratio were assessed before Ramadan and three months post-Ramadan. Results: Voluntary fasting practices increased only in group A (P <0.01. Additionally, the quantity of protein/carbohydrates consumed per day, mean diastolic pressure and TC:HDL-C ratio decreased only in group A (P <0.01, 0.05, 0.02 and <0.01, respectively. Frequency of fruit/vegetable consumption per week, as well as HDL-C levels, increased only in group A (P = 0.03 and <0.01, respectively. Although changes in BMI between the groups was not significant (P = 0.08, BMI decrease among participants in group A was significant (P <0.01. Conclusion: Control of post-Ramadan weight gain was more evident in the faith-based intervention group. Healthcare providers should consider faith-based interventions to encourage weight loss during Ramadan and to prevent post-Ramadan weight gain among patients.

    This study assessed the acceptability and preference for sexual barrier and lubricant products among men in Zambia following trial and long-term use. It also examined the role of men's preferences as facilitators or impediments to product use for HIV transmission reduction within the Zambian context. HIV-seropositive and -serodiscordant couples were recruited from HIV voluntary counseling and testing centers in Lusaka between 2003 and 2006; 66% of those approached agreed to participate. HIV seropositive male participants participated in a product exposure group intervention (n = 155). Participants were provided with male and female condoms and vaginal lubricants (Astroglide [BioFilm, Inc., Vista, CA] & KY gels [Johnson & Johnson, Langhorne, PA], Lubrin suppositories [Kendwood Therapuetics, Fairfield, NJ]) over three sessions; assessments were conducted at baseline, monthly over 6 months and at 12 months. At baseline, the majority of men reported no previous exposure to lubricant products or female condoms and high (79%) levels of consistent male condom use in the last 7 days. Female condom use increased during the intervention, and male condom use increased at 6 months and was maintained over 12 months. The basis for decisions regarding lubricant use following product exposure was most influenced by a preference for communicating with partners; participant preference for lubricant products was distributed between all three products. Results illustrate the importance of development of a variety of products for prevention of HIV transmission and of inclusion of male partners in interventions to increase sexual barrier product use to facilitate barrier acceptability and use in Zambia.

    2006-06-01

    A novel two-step paradigm was used to investigate the parallel programming of consecutive, stimulus-elicited ('reflexive') and endogenous ('voluntary') saccades. The mean latency of voluntary saccades, made following the first reflexive saccades in two-step conditions, was significantly reduced compared to that of voluntary saccades made in the single-step control trials. The latency of the first reflexive saccades was modulated by the requirement to make a second saccade: first saccade latency increased when a second voluntary saccade was required in the opposite direction to the first saccade, and decreased when a second saccade was required in the same direction as the first reflexive saccade. A second experiment confirmed the basic effect and also showed that a second reflexive saccade may be programmed in parallel with a first voluntary saccade. The results support the view that voluntary and reflexive saccades can be programmed in parallel on a common motor map.

    We study the effect of voluntary participation in the context of a collective-good experiment. We investigate whether the freedom to participate in the game or not increases contribution levels and enhances their evolution. The analysis of two voluntary participation treatments supports a positive effect of an attractive exit option on both contribution levels and their sustainability. We conclude that the voluntary contribution mechanism can provide sustainable cooperation levels and that th...

    2009-04-01

    Luxation of the globe is rare in the general population and may be spontaneous, voluntary, or traumatic. Spontaneous or voluntary globe luxation results from shallow orbit, floppy eyelids, lax orbital ligaments, backward displacement of orbital septum, or proptotic eyes due to orbital tumors or infiltrative processes, as in Grave's ophthalmopathy. The authors report a case with unilateral voluntary globe luxation presented with unilateral progressive visual loss.

    Towns, Alison J; Terry, Gareth

    2014-08-01

    This study reports on discourse analysis of transcripts from focus group discussions held with 28 "ordinary" men about domestic violence. Two broad "mateship" themes emerged: (a) a strong "mateship" discourse that produced public/private boundaries around discussions about intimate heterosexual relationships. Policed by the threat of violence, these boundaries prevented some men from challenging men about their violence. (b) "Loyalty to mates" discourses constituted attention to men's violence against women as threatening the moral integrity of all men. Finally, some men positioned themselves against men's domestic violence, distinguishing their masculinity from men who abuse women. Implications for prevention campaigns are discussed.

  12. Voluntary limit setting and player choice in most intense online gamblers: an empirical study of gambling behaviour.

    Auer, Michael; Griffiths, Mark D

    2013-12-01

    Social responsibility in gambling has become a major issue for the gaming industry. The possibility for online gamblers to set voluntary time and money limits are a social responsibility practice that is now widespread among online gaming operators. The main issue concerns whether the voluntary setting of such limits has any positive impact on subsequent gambling behaviour and whether such measures are of help to problem gamblers. In this paper, this issue is examined through data collected from a representative random sample of 100,000 players who gambled on the win2day gambling website. When opening an account at the win2day site, there is a mandatory requirement for all players to set time and cash-in limits (that cannot exceed 800 per week). During a 3-month period, all voluntary time and/or money limit setting behaviour by a subsample of online gamblers (n = 5,000) within this mandatory framework was tracked and recorded for subsequent data analysis. From the 5,000 gamblers, the 10 % most intense players (as measured by theoretical loss) were further investigated. Voluntary spending limits had the highest significant effect on subsequent monetary spending among casino and lottery gamblers. Monetary spending among poker players significantly decreased after setting a voluntary time limit. The highest significant decrease in playing duration was among poker players after setting a voluntary playing duration limit. The results of the study demonstrated that voluntary limit setting had a specific and significant effect on the studied gamblers. Therefore, voluntary limits appear to show an appropriate effect in the desired target group (i.e., the most gaming intense players).

  14. Voluntary self-touch increases body ownership

    2015-10-01

    Full Text Available Experimental manipulations of body ownership have indicated that multisensory integration is central to forming bodily self-representation. Voluntary self-touch is a unique multisensory situation involving corresponding motor, tactile and proprioceptive signals. Yet, even though self-touch is frequent in everyday life, its contribution to the formation of body ownership is not well understood. Here we investigated the role of voluntary self-touch in body ownership using a novel adaptation of the rubber hand illusion (RHI, in which a robotic system and virtual reality allowed participants self-touch of real and virtual hands. In the first experiment, active and passive self-touch were applied in the absence of visual feedback. In the second experiment, we tested the role of visual feedback in this bodily illusion. Finally, in the third experiment, we compared active and passive self-touch to the classical RHI in which the touch is administered by the experimenter. We hypothesized that active self-touch would increase ownership over the virtual hand through the addition of motor signals strengthening the bodily illusion. The results indicated that active self-touch elicited stronger illusory ownership compared to passive self-touch and sensory only stimulation, and indicate an important role of active self-touch in the formation of bodily self.

    Chronic exposure to the anabolic androgenic steroids (AAS) nandrolone decanoate (ND) in supra-physiological doses is associated with learning and memory impairments. Given the well-known beneficial effects of voluntary exercise on cognitive functions, we examined whether voluntary exercise would improve the cognitive deficits induced by chronic administration of ND. We also investigated the effects of ND and voluntary exercise on hippocampal BDNF levels. The rats were randomly distributed into 4 experimental groups: the vehicle-sedentary group, the ND-sedentary group, the vehicle-exercise group, and the ND-exercise group. The vehicle-exercise and the ND-exercise groups were allowed to freely exercise in a running wheel for 15 days. The vehicle-sedentary and the ND-sedentary groups were kept sedentary for the same period. Vehicle or ND injections were started 14 days prior to the voluntary exercise and continued throughout the 15 days of voluntary exercise. After the 15-day period, the rats were trained and tested on a water maze spatial task using four trials per day for 5 consecutive days followed by a probe trial two days later. Exercise significantly improved performance during both the training and retention of the water maze task, and enhanced hippocampal BDNF. ND impaired spatial learning and memory, and this effect was not rescued by exercise. ND also potentiated the exercise-induced increase in hippocampal BDNF levels. These results seem to indicate that voluntary exercise is unable to improve the disruption of cognitive functions by chronic ND. Moreover, increased levels of BDNF may play a role in ND-induced impairments in learning and memory. The harmful effects of ND and other AAS on learning and memory should be taken into account when athletes decide to use AAS for performance or body image improvement.

    2016-09-01

    This article reviews the use of transcranial magnetic stimulation (TMS) over the motor cortex to make estimates of the level of voluntary drive to muscles. The method, described in 2003 (Todd et al. J Physiol 551: 661-671, 2003), uses a TMS pulse to produce descending corticospinal volleys that synaptically activate motoneurons, resulting in a muscle twitch. Linear regression of the superimposed twitch amplitude and voluntary force (or torque) can generate an "estimated" resting twitch for muscles involved in a task. This procedure has most commonly been applied to elbow flexors but also to knee extensors and other muscle groups. Data from 44 papers using the method were tabulated. We identify and discuss five major technical challenges, and the frequency with which they are addressed. The technical challenges include inadvertent activation of the cortical representation of antagonist muscles, the role of antagonist torques at the studied joint, uncertainty about the effectiveness of the TMS pulse in activating the motoneuron pool, the linearity of the voluntary force (or torque) and superimposed twitch relationship, and variability in the TMS-evoked EMG and force/torque responses. The ideal situation in which the descending corticospinal volleys recruit all of the agonist motoneurons and none of the antagonist motoneurons is unlikely to ever occur, and hence results must be carefully examined to assess the authenticity of the voluntary activation estimates in the context of the experimental design. A partial compromise lies in the choice of stimulus intensity. We also identify aspects of the procedure that require further investigation.

    Action observation activates brain areas involved in performing the same action and has been shown to increase motor learning, with potential implications for neurorehabilitation. Recent work indicates that the effects of action observation on movement can be increased by motor imagery or by directing attention to observed actions. In voluntary imitation, activation of the motor system during action observation is already increased. We therefore explored whether imitation could be further enhanced by imagery or attention. Healthy participants observed and then immediately imitated videos of human hand movement sequences, while movement kinematics were recorded. Two blocks of trials were completed, and after the first block participants were instructed to imagine performing the observed movement (Imagery group, N = 18) or attend closely to the characteristics of the movement (Attention group, N = 15), or received no further instructions (Control group, N = 17). Kinematics of the imitated movements were modulated by instructions, with both Imagery and Attention groups being closer in duration, peak velocity and amplitude to the observed model compared with controls. These findings show that both attention and motor imagery can increase the accuracy of imitation and have implications for motor learning and rehabilitation. Future work is required to understand the mechanisms by which these two strategies influence imitation accuracy.

    Abstract Self-poisoning is an important medical and social problem in adolescents. We performed an observational cross-sectional retrospective study on a group of 219 adolescents admitted for voluntary intoxications at “St. Mary” Children's Emergency Hospital, Iasi during 1 year period. Epidemiological aspects and triggering factors have been analyzed. Data collected from the patients’ files were centralized in an SPSS 18.0 database and processed with confidence interval of 95%. We found that pharmaceutical drugs have been usually involved (34.7%), mostly in girls (56.3% vs. 15.5%; P = 0.0001). The most frequently cited reason for poisoning was family conflict, with a relative risk (RR) 1.43 times higher in girls, as well as scholar conflict (RR = 1.39). A great percentage of the monitored girls presented severe depression (23.3% vs. 6.9%; P = 0.001), with an RR more than 3 times higher than in the case of boys. All cases evolved favorably, no death having been recorded, even if 18 teenagers initially presented an extremely serious condition, being admitted in various stages of coma (Glasgow coma scale score poisonings with pharmaceutical drugs was more common in girls and the use of drug and alcohol intoxication was found especially in boys. The most common pharmaceutical drug involved in self-poisoning was acetaminophen. Psychological disorders and family or school conflicts are the most important triggering factors of voluntary poisoning. Risk factors should be identified after stabilizing the patient, and actions should be taken in order to prevent a fatal recurrence. PMID:28151858

    Whether there is a gender difference in fatigue and recovery from maximal velocity fatiguing contractions and across muscles is not understood. Sixteen men and 19 women performed 90 isotonic contractions at maximal voluntary shortening velocity (maximal velocity concentric contractions, MVCC) with the elbow flexor and knee extensor muscles (separate days) at a load equivalent to 20% maximal voluntary isometric contraction (MVIC). Power (from MVCCs) decreased similarly for men and women for both muscles (P > 0.05). Men and women had similar declines in MVIC of elbow flexors, but men had greater reductions in knee extensor MVIC force and MVIC electromyogram activity than women (P contractions for upper and lower limb muscles.

  16. Lateral asymmetry of voluntary attention orienting

    Directory of Open Access Journals (Sweden)

    B.A. Castro-Barros

    2010-08-01

    Full Text Available We recently demonstrated that automatic attention favors the right side of space and, in the present study, we investigated whether voluntary attention also favors this side. Six reaction time experiments were conducted. In each experiment, 12 new 18-25-year-old male right-handed individuals were tested. In Experiments 1, 2, 3 (a, b and 4 (a, b, tasks with increasing attentional demands were used. In Experiments 1, 2, 3a, and 4a, attention was oriented to one or both sides by means of a central spatially informative visual cue. A left or right side visual target appeared 100, 300, or 500 ms later. Attentional effects were observed in the four experiments. In Experiments 2, 3a and 4a, these effects were greater when the cue indicated the right side than when it indicated the left side (respectively: 16 ± 10 and 44 ± 6 ms, P = 0.015, for stimulus onset asynchrony of 500 ms in Experiment 2; 38 ± 10 and 70 ± 7 ms, P = 0.011, for Experiment 3a, and 23 ± 11 and 61 ± 10 ms, P = 0.009, for Experiment 4a. In Experiments 3b and 4b, the central cue pointed to both sides and was said to be non-relevant for task performance. In these experiments right and left reaction times did not differ. The most conservative interpretation of the present findings is that voluntary attention orienting favors the right side of space, particularly when a difficult task has to be performed.

    2015-01-01

    The purpose of this study was to examine the acute effects of maximal concentric vs. eccentric exercise on the isometric strength of the elbow flexor, as well as the biceps brachii muscle electromyographic (EMG) responses in resistance-trained (RT) vs. untrained (UT) men. Thirteen RT men (age: 24 ± 4 years; height: 180.2 ± 7.7 cm; body weight: 92.2 ± 16.9 kg) and twelve UT men (age: 23 ± 4 years; height: 179.2 ± 5.0 cm; body weight: 81.5 ± 8.6 kg) performed six sets of ten maximal concentric isokinetic (CON) or eccentric isokinetic (ECC) elbow flexion exercise in two separate visits. Before and after the exercise interventions, maximal voluntary contractions (MVCs) were performed for testing isometric strength. In addition, bipolar surface EMG signals were detected from the biceps brachii muscle during the strength testing. Both CON and ECC caused isometric strength to decrease, regardless of the training status. However, ECC caused greater isometric strength decline than CON did for the UT group (p = 0.006), but not for the RT group. Both EMG amplitude and mean frequency significantly decreased and increased, respectively, regardless of the training status and exercise intervention. Resistance-trained men are less susceptible to eccentric exercise-induced muscle damage, but this advantage is not likely linked to the chronic resistance training-induced neural adaptations.

  18. Aging Men and Prostate Cancer

    Directory of Open Access Journals (Sweden)

    Thompson B

    2015-01-01

    Full Text Available Prostate cancer (PCa is one of the most commonly diagnosed cancers in men worldwide and its incidence increases with age, mainly affecting elderly men aged 60 and above. Factors known to be associated with the development and progression of PCa are age, family history, and race/ethnicity, with age being the most important factor. The reasons for the increased incidence and mortality due to prostate cancer in elderly men are not entirely clear. Continued exposure to environmental and dietary factors may lead to accumulation of genetic and epigenetic changes over the life-span, leading to altered expression and/or activity of tumor promoter and tumor suppressor genes. Changing levels of endogenous hormones (like androgens and metabolism in elderly men may also play a role in the development of prostate cancers which may be further influenced by testosterone replacement therapy. For many decades now preventative strategies and treatments such as radiation therapy or hormone therapy, and others have been administered to manage PCa; however current studies and evidence suggest that PCa is undertreated in elderly men, despite evidence of efficacy of these treatments, which leads to higher prevalence of mortality in this age group. Studies involving basic research, preventative and management strategies are still underway to understand the mechanisms of PCa development in elderly men and treatment of this disease in ageing male population.

    The goal of this study was to show that voluntary autobiographical memories could be primed by the prior activation of autobiographical memories. Three experiments demonstrated voluntary memory priming with three different approaches. In Experiment 1 primed participants were asked to recall memories from their elementary school years. In a subsequent memory task primed participants were asked to recall memories from any time period, and they produced significantly more memories from their elementary school years than unprimed participants. In Experiment 2 primed participants were asked to recall what they were doing when they had heard various news events occurring between 1998 and 2005. Subsequently these participants produced significantly more memories from this time period than unprimed participants. In Experiment 3 primed participants were asked to recall memories from their teenage years. Subsequently these participants were able to recall more memories from ages 13-15 than unprimed participants, where both had only 1 second to produce a memory. We argue that the results support the notion that episodic memories can activate one another and that some of them are organised according to lifetime periods. We further argue that the results have implications for the reminiscence bump and voluntary recall of the past.

    The prevalence of cooperation among humans is puzzling because cooperators can be exploited by free riders. Peer punishment has been suggested as a solution to this puzzle, but cumulating evidence questions its robustness in sustaining cooperation. Amongst others, punishment fails when it is not powerful enough, or when it elicits counter-punishment. Existing research, however, has ignored that the distribution of punishment power can be the result of social interactions. We introduce a novel experiment in which individuals can transfer punishment power to others. We find that while decentralised peer punishment fails to overcome free riding, the voluntary transfer of punishment power enables groups to sustain cooperation. This is achieved by non-punishing cooperators empowering those who are willing to punish in the interest of the group. Our results show how voluntary power centralisation can efficiently sustain cooperation, which could explain why hierarchical power structures are widespread among animals and humans.

    Background Differences in risk behaviours between men who have sex with men and men who have sex with both men and women have important implications for HIV and STI transmission. We examined differences in risk behaviours, HIV/STI testing, self-reported HIV/STI diagnoses, and linkage to HIV care between men who have sex with men and men who have sex with both men and women across China. Methods Participants were recruited through three men who have sex with men-focused websites in China. An online survey containing items on socio-demographics, risk behaviours, testing history, self-reported HIV/STI diagnosis, and linkage to and retention in HIV care was completed from September to October 2014. Chi square tests and logistic regression analyses were conducted. Results Men who have sex with both men and women were less likely to use a condom during last anal sex (p ≤ 0.01) and more likely to engage in group sex (p ≤ 0.01) and transactional sex (p ≤ 0.01) compared to men who have sex with men. Self-reported HIV/STI testing and positivity rates between men who have sex with men and men who have sex with both men and women were similar. Among HIV-infected men who have sex with men, there was no difference in rates of linkage to or retention in antiretroviral therapy when comparing men who have sex with men and men who have sex with both men and women. Conclusions Chinese men who have sex with men and men who have sex with both men and women may benefit from different HIV and STI intervention and prevention strategies. Achieving a successful decrease in HIV/STI epidemics among Chinese men who have sex with men and men who have sex with both men and women will depend on the ability of targeted and culturally congruent HIV/STI control programmes to facilitate a reduction in risk behaviours.

    Abstract With efforts focused on the elimination of maternal and neonatal tetanus, less attention has been given to tetanus incidence and mortality among men. Since 2007 voluntary medical male circumcision has been scaled-up in 14 sub-Saharan African countries as an effective intervention to reduce the risk of human immunodeficiency virus (HIV) acquisition among men. As part of a review of adverse events from these programmes, we identified 13 cases of tetanus from five countries reported to the World Health Organization (WHO) up to March 2016. Eight patients died and only one patient had a known history of tetanus vaccination. Tetanus after voluntary medical male circumcision was rare among more than 11 million procedures conducted. Nevertheless, the cases prompted a review of the evidence on tetanus vaccination coverage and case notifications in sub-Saharan Africa, supplemented by a literature review of non-neonatal tetanus in Africa over the years 2003–2014. The WHO African Region reported the highest number of non-neonatal tetanus cases per million population and lowest historic coverage of tetanus-toxoid-containing vaccine. Coverage of the third dose of diphtheria–tetanus–polio vaccine ranged from 65% to 98% across the 14 countries in 2013. In hospital-based studies, non-neonatal tetanus comprised 0.3–10.7% of admissions, and a median of 71% of patients were men. The identification of tetanus cases following voluntary medical male circumcision highlights a gender gap in tetanus morbidity disproportionately affecting men. Incorporating tetanus vaccination for boys and men into national programmes should be a priority to align with the goal of universal health coverage. PMID:27516639

    This qualitative study aimed to examine cultural differences in knowledge, attitudes and practices related to erectile dysfunction (ED) utilizing focus group discussion. Six focus groups consisting of 66 men, 45-70-y-old were conducted-two Malay groups (n=18), two Chinese groups (n=25) and two Indian groups (n=23). Participants were purposely recruited from the general public on a voluntary basis with informed consent. Transcripts were analyzed using qualitative data analysis software ATLASti. The Malay and Chinese traditional remedies for preventing or treating ED are commonly recognized among all races. Many have a negative perception of someone with ED. Malay and Chinese men tended to blame their wife for their problem and thought that the problem might lead to extra-marital affairs, unlike the Indian men who attributed their condition to fate. Malays would prefer traditional medicine for the problem. The Chinese felt they would be more comfortable with a male doctor whilst this is not so with the Malays or Indians. Almost all prefer the doctor to initiate discussion on sexual issues related to their medical condition. There is a need for doctors to consider cultural perspectives in a multicultural society as a lack of understanding of this often contributes to an inadequate consultation.

  6. Effects of 7-keto Dehydroepiandrosterone on Voluntary Ethanol Intake in Male Rats

    Administration of dehydroepiandrosterone (DHEA), a neurosteroid that can negatively modulate the GABAA receptor, has been shown to decrease voluntary intake of ethanol in rats. In vivo, DHEA can be metabolized to a variety of metabolites, including 7-keto DHEA, a metabolite without the prohormonal effects of DHEA. This study compared the effectiveness of 7-keto DHEA to DHEA for reducing ethanol intake in the same group of rats. The subjects, previously trained to drink ethanol using a sacchar...

    This paper provides a new way to identify conditional cooperation in a real-time version of the standard voluntary contribution mechanism. We define contribution cycles as the number of contributors a player waits for before committing to a further contribution, and use a permutation test on contribution cycles to assign a measure of conditional cooperation to each group play. The validity of the measures is tested in an experiment. We find that roughly 20% of the plays exhibit dynamics of co...

    2000-11-01

    This paper describes the development and use of a modified SERVQUAL research instrument for measuring the service quality of voluntary organizations from the perspective of their 'customers'. A series of focus group meetings were run with providers and users of the services to identify the appropriate dimensions of service quality. These were structured meetings led by the researchers addressing set questions in a group setting. The meeting enabled the identification of six different dimensions of service quality which neatly mapped on to the pivotal-core-peripheral (P-C-P attributes model [Philip and Hazlett, 1997]), which was developed after extensive research of existing models such as SERVQUAL. These dimensions were used to develop a questionnaire to assess service quality within the voluntary sector. The questionnaire was distributed to 2005 service users, representing eight voluntary organizations from across Northern Ireland. The research resulted in the development of a methodology and research instrument suitable for measuring service quality in the voluntary sector.

    We have measured the cardiovascular responses during voluntary and nonvoluntary (electrically induced) one-leg static exercise in humans. Eight normal subjects were studied at rest and during 5 min of static leg extension at 20% of maximal voluntary contraction performed voluntarily and nonvoluntarily in random order. Heart rate (HR), mean arterial pressure (MAP), and cardiac output (CO) were determined, and peripheral vascular resistance (PVR) and stroke volume (SV) were calculated. HR increased from approximately 65 +/- 3 beats/min at rest to 80 +/- 4 and 78 +/- 6 beats/min (P voluntary and nonvoluntary contractions, respectively. CO increased from 5.1 +/- 0.7 to 6.0 +/- 0.8 and 6.2 +/- 0.8 l/min (P voluntary and nonvoluntary contractions, respectively. PVR and SV did not change significantly during voluntary or nonvoluntary contractions. Thus the cardiovascular responses were not different between voluntary and electrically induced contractions. These results suggest that the increases in CO, HR, SV, MAP, and PVR during 5 min of static contractions can be elicited without any contribution from a central neural mechanism (central command). However, central command could still have an important role during voluntary static exercise.

    To collect information about HPV in men and the (possible) correlation with HVP infection in women. Review of the literature. An overview of HPV-related penile and anal malignancies in men and the risk factors of acquiring HPV. In men HPV is also partially responsible for anogenital malignancies. Although the prevalence of HPV-related malignancies in men is much lower than in women, it is useful to gain more knowlege. Especially knowing if men are really the HPV reservoir and transmitters for women can make a difference in deciding whether men should also be screened for HPV and if they are good candidates for vaccination.

  14. Triceps surae contractile properties and firing rates in the soleus of young and old men.

    Mean maximal motor unit firing rates (MUFRs) of the human soleus are lower (5-20 Hz) than other limb muscles (20-50 Hz) during brief sustained contractions. With healthy adult aging, maximal MUFRs are 20-40% lower and twitch contractile speed of lower limb muscles are 10-40% slower compared with young adults. However, it is unknown whether the inherently low maximal MUFRs for the soleus are further reduced with aging in association with age-related slowing in contractile properties. The purpose of the present study was to compare the changes in triceps surae contractile properties and MUFRs of the soleus throughout a variety of contraction intensities in six old ( approximately 75 yr old) and six young ( approximately 24 yr old) men. Neuromuscular measures were collected from the soleus and triceps surae during repeated sessions (2-6 sessions). Populations of single MUFR trains were recorded from the soleus with tungsten microelectrodes during separate sustained 6- to 10-s isometric contractions of varying intensities [25%, 50%, 75%, and 100% maximal voluntary isometric contraction (MVC)]. The old men had weaker triceps surae strength (MVC; 35% lower) and slower contractile properties (contraction duration; 20% longer) than the young men. However, there was no difference in average MUFRs of the soleus at 75% and 100% MVC ( approximately 14.5 Hz and approximately 16.5 Hz, respectively). At 25% and 50% MVC, average rates were 10% and 20% lower in the old men compared with young, respectively. Despite a significant slowing in triceps surae contraction duration, there was no age-related change in MUFRs recorded at high contractile intensities in the soleus. Thus the relationship between the whole muscle contractile properties and MUFRs found in other muscle groups may not exist between the triceps surae and soleus and may be muscle dependent.

    One of the main concept objectives of smart cities is to create a quality living environment that is long-term sustainable and economically justified. In that context, modern cities are aware of the exposure to various forms of physical and non-physical pollution that needs to be remediated, eliminated or reduced. To achieve that it is necessary to quality determine the sources and reasons of each pollution. The most prominent examples of physical pollution that affects the quality of life of citizens in cities are light and noise pollution. Noise pollution or noise, is mostly the consequence of road and rail traffic in cities and it directly affects the health of citizens. Traffic control, reduction of peak congestion, dispersion and traffic redirection or building protective barriers, are ways that cities use to reduce the amount of noise or its effects. To make these measures efficient it is necessary to obtain the information related to the level of noise in certain areas, streets, cities. To achieve this, smart cities use noise mapping. The city of Zagreb since 2012, participates in the i-SCOPE project (interoperable Smart City services trough Open Platform for urban Ecosystems). i-SCOPE delivers an open platform on top of which it develops, three "smart city" services: optimization of energy consumption through a service for accurate assessment of solar energy potential and energy loss at building level, environmental monitoring through a real-time environmental noise mapping service leveraging citizen's involvement will who act as distributed sensors city-wide measuring noise levels through an application on their mobile phones and improved inclusion and personal mobility of aging and diversely able citizens through an accurate personal routing service.

  19. Impaired Interlimb Coordination of Voluntary Leg Movements in Poststroke Hemiparesis

    Tseng, Shih-Chiao

    2010-01-01

    Appropriate interlimb coordination of the lower extremities is particularly important for a variety of functional human motor behaviors such as jumping, kicking a ball, or simply walking. Specific interlimb coordination patterns may be especially impaired after a lesion to the motor system such as stroke, yet this has not been thoroughly examined to date. The purpose of this study was to investigate the motor deficits in individuals with chronic stroke and hemiparesis when performing unilateral versus bilateral inphase versus bilateral antiphase voluntary cyclic ankle movements. We recorded ankle angular trajectories and muscle activity from the dorsiflexors and plantarflexors and compared these between subjects with stroke and a group of healthy age-matched control subjects. Results showed clear abnormalities in both the kinematics and EMG of the stroke subjects, with significant movement degradation during the antiphase task compared with either the unilateral or the inphase task. The abnormalities included prolonged cycle durations, reduced ankle excursions, decreased agonist EMG bursts, and reduced EMG modulation across movement phases. By comparison, the control group showed nearly identical performance across all task conditions. These findings suggest that stroke involving the corticospinal system projection to the leg specifically impairs one or more components of the neural circuitry involved in lower extremity interlimb coordination. The express susceptibility of the antiphase pattern to exaggerated motor deficits could contribute to functional deficits in a number of antiphase leg movement tasks, including walking.

    Both voluntary and involuntary movements activate sensors in the muscles, skin, tendon and joints. As limb movement can result from a mixture of spinal reflexes and voluntary motor commands, the cortical centres underlying conscious proprioception might either aggregate or separate the sensory inputs generated by voluntary movements from those generated by involuntary movements such as spinal reflexes. We addressed whether healthy volunteers could perceive the contribution of a spinal reflex during movements that combined both reflexive and voluntary contributions. Volunteers reported the reflexive contribution in leg movements that were partly driven by the knee-jerk reflex induced by a patellar tendon tap and partly by voluntary motor control. In one condition, participants were instructed to kick back in response to a tendon tap. The results were compared to reflexes in a resting baseline condition without voluntary movement. In a further condition, participants were instructed to kick forwards after a tap. Volunteers reported the perceived reflex contribution by repositioning the leg to the perceived maximum displacement to which the reflex moved the leg after each tendon tap. In the resting baseline condition, the reflex was accurately perceived. We found a near-unity slope of linear regressions of perceived on actual reflexive displacement. Both the slope value and the quality of regression fit in individual volunteers were significantly reduced when volunteers were instructed to generate voluntary backward kicks as soon as they detected the tap. In the kick forward condition, kinematic analysis showed continuity of reflex and voluntary movements, but the reflex contribution could be estimated from electromyography (EMG) recording on each trial. Again, participants' judgements of reflexes showed a poor relation to reflex EMG, in contrast to the baseline condition. In sum, we show that reflexes can be accurately perceived from afferent information. However

    In recent years, both compliance and voluntary markets have emerged to help support the development of renewable energy resources. Both of these markets are growing rapidly and today about half of U.S. states have RPS policies in place, with a number of these policies adopted in the last several years. In addition, many states have recently increased the stringency of their RPS policies. This paper examines key market interaction issues between compliance and voluntary renewable energy markets. It provides an overview of both the compliance and voluntary markets, addressing each market's history, purpose, size, scope, and benefits while addressing issues, including double counting.

    Full Text Available Background Sexuality is a part of one’s identity and personality that is shaped under the influence of biological and environmental factors and interactions with society. The results of research conducted so far and concerning the personality traits of gay men and women are not consistent, and only a small number of them concern the Polish population. Hence the objective of the present research was to provide personality profiles of men and women with different sexual orientations. Participants and procedure The participants (N = 346 included 84 gay women, 82 gay men, 95 heterosexual women and 85 heterosexual men. The following measures were used: a survey developed by the author, the Kinsey Scale, the EPQ-R (Eysenck Personality Questionnaire Revised adapted by Brzozowski and Drwal (1995, and the Sixteen-factor Personality Questionnaire of Cattell adapted by Nowakowska (1970. Results The results support the hypothesis that gay women and heterosexual men share similar personality traits, while gay men have more diverse traits, similar to the traits typical for heterosexual women and men. In particular, personalities of gay men are described by such traits as progressive attitude, independence, or willingness to take risks, which means traits linked to factor Q1. The highest values of that factor are observable in the case of gay men, as compared to gay women, and also in comparison with heterosexual men and women. Conclusions Sexual orientation is responsible for differences in personality traits of the studied group to a greater extent than their biological sex.

    This is the first study on the prevalence of dating violence and threats of being forced to "come out of the closet" among Chinese gay men. Data on social demographic information and the experience of dating violence, including types of abuse, threats of "outing," and the gender of abusers were collected from 418 gay men and 330 heterosexual men by self-administered questionnaires. Mann-Whitney U test, χ(2) test, and multivariate logistic regression analyses were used to test group differences. Up to 32.8% of the gay men had experienced one abuse or more. Among those experiencing abuse, 83.9% of the gay men never told anyone about their abuse. The experience of any form of abuse by gay men was 5.07 times higher than the rate of abuse among heterosexual men controlling for age in logistic regression models. In addition, 12.4% of the gay men have experienced the threat of being outed. Overall, dating violence is more prevalent in gay men than in heterosexuals. Efforts to prevent dating violence, especially among gay men, should be made in China.

    Alcohol use disorder (AUD) is a worldwide public health problem and a polygenetic disorder displaying substantial individual variation. This work aimed to study individual differences in behavior and its association to voluntary alcohol intake and subsequent response to naltrexone in a seamless heterogenic group of animals. Thus, by this approach the aim was to more accurately recapitulate the existing heterogeneity within the human population. Male Wistar rats from three different suppliers (Harlan Laboratories B.V., RccHan™:WI; Taconic Farms A/S, HanTac:WH; and Charles River GmbH, Crl:WI) were used to create a heterogenic group for studies of individual differences in behavior, associations to intermittent voluntary alcohol intake and subsequent response to naltrexone. The rats were tested in the open field prior to the Y-maze and then given voluntary intermittent access to alcohol or water in the home cage for 6 weeks, where after, naltrexone in three different doses or saline was administered in a Latin square design over 4 weeks and alcohol intake and preference was measured. However, supplier-dependent differences and concomitant skew subgroup formations, primarily in open field behavior and intermittent alcohol intake, resulted in a shifted focus to instead study voluntary alcohol intake and preference, and the ensuing response to naltrexone in Wistar rats from three different suppliers. The results showed that outbred Wistar rats are diverse with regard to voluntary alcohol intake and preference in a supplier-dependent manner; higher in RccHan™:WI relative to HanTac:WH and Crl:WI. The results also revealed supplier-dependent differences in the effect of naltrexone that were dose- and time-dependent; evident differences in high-drinking RccHan™:WI rats relative to HanTac:WH and Crl:WI rats. Overall these findings render RccHan™:WI rats more suitable for studies of individual differences in voluntary alcohol intake and response to naltrexone and

    2008-07-01

    Full Text Available Nowadays, when the welfare state is a responsibility of the entire society, organizations in the private sector assume co-responsibility for social issues. They are also pressured by the challenges presented by technological advances and the globalization , involving new parameters and requirements for quality. In this context, the concept of Corporate Social Responsibility (RSC emerges as an option for solutions to the issues related to the company and the whole community. Among the actions of the RSC is the Corporate Volunteering-program, which aims to promote / encourage employes to do voluntary work. A central issue when talking about volunteering is the withdrawal of these (SILVA and FEITOSA, 2002; TEODÓSIO, 1999 and, in accordance with the Community Solidarity (1997, one of the possible causes for the withdrawal is the lack of clarity as to the motives and expectations that lead the person to volunteer themselves. This study uses qualitative research and triangulation of feedback from volunteers, coordinators of volunteers and social organizations, to present a framework from which it is possible to analyze the various motivations for the volunteer work. Key words: Corporate Volunteering program. Volunteering. Corporate social responsibility.

  13. Expectations and voluntary attrition in nursing students.

    2011-01-01

    This paper presents a series of findings generated during a larger study which aimed to develop a theoretical understanding of the reasons why nursing students voluntarily leave pre-registration nursing programmes. In this study, significant incongruence was found to exist between student expectations of pre-registration nursing programmes and the reality of these programmes following entry. The resulting dissonance was identified as an important factor in student decisions to voluntarily withdraw. A single case study design was selected to explore the causes of voluntary attrition in nursing students within a School of Nursing and Midwifery. The study population was obtained through purposeful sampling and consisted of 15 students who had previously voluntarily withdrawn from pre-registration nursing programmes. A semi-structured interview method was used to collect data from study participants. The interview schedule developed for use in the study reflected the key components of the conceptual model of higher education (HE) student attrition (Tinto, 1975, 1987, 1993). All interviews were tape recorded to facilitate later transcription. The Cyclical or Interactive Model of Qualitative Research (Miles and Huberman, 1994) was used to analyse data collected from study participants. This paper describes the unrealistic range of expectations which nursing students have of nursing, the information sources and experiences which inform student expectations and how ambiguous expectations contributed to voluntarily attrition.

  14. Perceived coercion in voluntary hospital admission.

    O'Donoghue, Brian

    2014-01-30

    The legal status of service users admitted to psychiatric wards is not synonymous with the level of coercion that they can perceive during the admission. This study aimed to identify and describe the proportion of individuals who were admitted voluntarily but experienced levels of perceived coercion comparable to those admitted involuntarily. Individuals admitted voluntarily and involuntarily to three psychiatric hospitals were interviewed using the MacArthur Admission Experience Interview and the Structured Clinical Interview for DSM-IV diagnoses. One hundered sixty-one individuals were interviewed and 22% of the voluntarily admitted service users had levels of perceived coercion similar to that of the majority of involuntarily admitted service users. Voluntarily admitted service users who experienced high levels of perceived coercion were more likely to have more severe psychotic symptoms, have experienced more negative pressures and less procedural justices on admission. Individuals brought to hospital under mental health legislation but who subsequently agreed to be admitted voluntarily and those treated on a secure ward also reported higher levels of perceived coercion. It needs to be ensured that if any service user, whether voluntary or involuntary, experiences treatment pressures or coercion that there is sufficient oversight of the practice, to ensure that individual\\'s rights are respected.

  15. Sexual Stereotypes Ascribed to Black Men Who Have Sex with Men: An Intersectional Analysis.

    Sexual stereotypes may adversely affect the health of Black men who have sex with men (MSM). Greater understanding of the nature and nuances of these stereotypes is needed. This online, survey-based study used an inductive, intersectional approach to characterize the sexual stereotypes ascribed to Black MSM by the U.S. general public, their distinctiveness from those ascribed to Black men and MSM in general, and their relative prototypicality as compared to dominant subgroups. Members of the public, recruited in 2014-2015, were randomly assigned to survey conditions that varied systematically by race (Black, White, or unspecified) and sexual orientation (gay, heterosexual, or unspecified) of a designated social group. Participants (n = 285) reported stereotypes of their assigned group that they perceived to exist in U.S. culture in an open-response format. Cross-condition comparisons revealed that, overall, Black gay male stereotypes were non-prototypical of Black men or gay men. Rather, stereotypes of Black men were more similar to Black heterosexual men and stereotypes of gay men were more similar to White gay men. Nonetheless, 11 of the 15 most frequently reported Black gay male stereotypes overlapped with stereotypes of Black men (e.g., large penis), gay men (e.g., deviant), or both (e.g., promiscuous). Four stereotypes were unique relative to both Black men and gay men: down low, diseased, loud, and dirty. Findings suggest that Black MSM face multiple derogatory sexual stereotypes, several of which are group-specific. These stereotypes are consistent with cultural (mis)representations of Black MSM and suggest a need for more accurate portrayals of existing sexual diversity within this group.

  16. Support for voluntary and nonvoluntary euthanasia: what roles do conditions of suffering and the identity of the terminally ill play?

    Ho, Robert; Chantagul, Natalie

    2015-01-01

    This study investigated the level of support for voluntary and nonvoluntary euthanasia under three conditions of suffering (pain; debilitated nature of the body; burden on the family) experienced by oneself, a significant other, and a person in general. The sample consisted of 1,897 Thai adults (719 males, 1,178 females) who voluntarily filled in the study's questionnaire. Initial multivariate analysis of variance indicated significant group (oneself, significant other, person in general) differences in level of support for voluntary and nonvoluntary euthanasia and under the three conditions of suffering. Multigroup path analysis conducted on the posited euthanasia model showed that the three conditions of suffering exerted differential direct and indirect influences on the support of voluntary and nonvoluntary euthanasia as a function of the identity of the person for whom euthanasia was being considered. The implications of these findings are discussed.

    This article reports research undertaken to inform a social marketing campaign targeting men's violence toward women in a city in northern England. Eighty-four men drawn from community groups participated in 15 focus groups. Participants struggled with wider definitions of domestic abuse and resisted depictions of men as wholly responsible for domestic violence. The potential loss of the relationship with children and, to a lesser degree, the relationship with their partner were identified as powerful incentives for changing abusive behavior. Men were particularly affected by the prospect of damage to their own self-image that children's perceptions of their fathers' violence conveyed.

  2. A critical test of the assumption that men prefer conformist women and women prefer nonconformist men.

    Five studies tested the common assumption that women prefer nonconformist men as romantic partners, whereas men prefer conformist women. Studies 1 and 2 showed that both men and women preferred nonconformist romantic partners, but women overestimated the extent to which men prefer conformist partners. In Study 3, participants ostensibly in a small-group interaction showed preferences for nonconformist opposite-sex targets, a pattern that was particularly evident when men evaluated women. Dating success was greater the more nonconformist the sample was (Study 4), and perceptions of nonconformity in an ex-partner were associated with greater love and attraction toward that partner (Study 5). On the minority of occasions in which effects were moderated by gender, it was in the reverse direction to the traditional wisdom: Conformity was more associated with dating success among men. The studies contradict the notion that men disproportionately prefer conformist women. © 2015 by the Society for Personality and Social Psychology, Inc.

    The aim of this work was to evaluate the goodness of fit of a signal issued of the respiratory inductance plethysmography (RIP) derivative to the airflow signal during rest, voluntary hyperventilation, and recovery. RIP derivative signal was filtered with an adjusted filter based on each subject airflow signal (pneumotachography). For each subject and for each condition (rest, voluntary hyperventilation, and recovery) comparisons were performed between the airflow signal and the RIP derivative signal filtered with an adjusted filter obtained either on rest signal or on the studied part of the signals (voluntary hyperventilation or recovery). Results show that the goodness of fit was : (1) higher than 90% at almost all comparisons (122 on 132), (2) not improved by applying an adjusted filter obtained on the studied part of the signals. These results suggest that RIP could be used for studying breathing during voluntary hyperventilation and recovery using adjusted filters obtained from comparison to airflow signal at rest.

    2011-05-01

    Environmental planners and managers face unique challenges understanding and documenting the effectiveness of programs that rely on voluntary actions by private landowners. Programs, such as those aimed at reducing nonpoint source pollution or improving habitat, intend to reach those goals by persuading landowners to adopt behaviors and management practices consistent with environmental restoration and protection. Our purpose with this paper is to identify barriers for improving voluntary environmental management programs and ways to overcome them. We first draw upon insights regarding data, learning, and adaptation from the adaptive management and performance management literatures, describing three key issues: overcoming information constraints, structural limitations, and organizational culture. Although these lessons are applicable to a variety of voluntary environmental management programs, we then present the issues in the context of on-going research for nonpoint source water quality pollution. We end the discussion by highlighting important elements for advancing voluntary program efforts.

  7. Assessing voluntary muscle activation with the twitch interpolation technique.

    Shield, Anthony; Zhou, Shi

    2004-01-01

    The twitch interpolation technique is commonly employed to assess the completeness of skeletal muscle activation during voluntary contractions. Early applications of twitch interpolation suggested that healthy human subjects could fully activate most of the skeletal muscles to which the technique had been applied. More recently, however, highly sensitive twitch interpolation has revealed that even healthy adults routinely fail to fully activate a number of skeletal muscles despite apparently maximal effort. Unfortunately, some disagreement exists as to how the results of twitch interpolation should be employed to quantify voluntary activation. The negative linear relationship between evoked twitch force and voluntary force that has been observed by some researchers implies that voluntary activation can be quantified by scaling a single interpolated twitch to a control twitch evoked in relaxed muscle. Observations of non-linear evoked-voluntary force relationships have lead to the suggestion that the single interpolated twitch ratio can not accurately estimate voluntary activation. Instead, it has been proposed that muscle activation is better determined by extrapolating the relationship between evoked and voluntary force to provide an estimate of true maximum force. However, criticism of the single interpolated twitch ratio typically fails to take into account the reasons for the non-linearity of the evoked-voluntary force relationship. When these reasons are examined, it appears that most are even more challenging to the validity of extrapolation than they are to the linear equation. Furthermore, several factors that contribute to the observed non-linearity can be minimised or even eliminated with appropriate experimental technique. The detection of small activation deficits requires high resolution measurement of force and careful consideration of numerous experimental details such as the site of stimulation, stimulation intensity and the number of interpolated

    Stretching a muscle of the upper limb elicits short (M1) and long-latency (M2) reflexes. When the participant is instructed to actively compensate for a perturbation, M1 is usually unaffected and M2 increases in size and is followed by the voluntary response. It remains unclear if the observed increase in M2 is due to instruction-dependent gain modulation of the contributing reflex mechanism(s) or results from voluntary response superposition. The difficulty in delineating between these alternatives is due to the overlap between the voluntary response and the end of M2. The present study manipulated response accuracy and complexity to delay onset of the voluntary response and observed the corresponding influence on electromyographic activity during the M2 period. In all active conditions, M2 was larger compared with a passive condition where participants did not respond to the perturbation; moreover, these changes in M2 began early in the appearance of the response (∼ 50 ms), too early to be accounted for by voluntary overlap. Voluntary response latency influenced the latter portion of M2, with the largest activity seen when accuracy of limb position was not specified. However, when participants aimed for targets of different sizes or performed movements of various complexities, reaction time differences did not influence M2 period activity, suggesting voluntary activity was sufficiently delayed. Collectively, our results show that while a perturbation applied to the upper limbs can trigger a voluntary response at short latency (reflex gain modulation remains an important contributor to EMG changes during the M2 period.

    Szasz and others have pointed out that many so-called voluntary admissions to mental hospitals have various elements of coercion involved, and are thus not truly voluntary. The author contends that the converse situation is also true, that many patients admitted under involuntary commitment papers arrange for their own commitments. Reasons for such choices are discussed in the context of a review of the literature and several case histories.

    2014-08-01

    Full Text Available Objectives: Recently in Poland as a result of the high rate of aging population and high rates of morbidity, a growing demand for the physiotherapist profession is observed. The results of this study can be used to formulate principles for better organization of physiotherapist's workplace in order to prevent occurrence of burnout. The aim of this study is to investigate the effect of gender on satisfaction with life and burnout among active physiotherapists. Material and Methods: The survey was anonymous and voluntary, and involved a group of 200 active physiotherapists working in health care units and educational centers in Poland. The study group was selected randomly and incidentally. Each respondent received a demographic data sheet and a set of self-rating questionnaires (Life Satisfaction Questionnaire, Burnout Scale Inventory. Results: Burnout among men decreased along with increasing satisfaction with one's work and occupation, friends, relatives and acquaintances, sexuality, and increased due to greater satisfaction with one's housing status. Burnout among women decreased along with increasing satisfaction with one's health, free time and friends, relatives and acquaintances, and increased due to work at a setting other than a health care unit or educational center. Statistical analysis failed to reveal any significant differences with regard to the BSI domains and with regard to the overall burnout index as well as with regard to the assessment of satisfaction with life between female and male physiotherapists. Conclusions: Satisfaction with children, marriage and partnership, with one's work and occupation, interactions with friends, relatives and acquaintances and sexuality may contribute to reduction of burnout among men. Women who are satisfied with their children, family, health, free time and contacts with friends, relatives and acquaintances are less prone to burnout.

    Functional electrical stimulation (FES) may be able to augment functional arm and hand movement after stroke. Poststroke neuroprostheses that incorporate voluntary effort and FES to produce the desired movement must consider how forces generated by voluntary effort and FES combine, even in the same muscle, in order to provide an appropriate level of stimulation to elicit the desired assistive force. The goal of this study was to determine whether the force produced by voluntary effort and FES add together independently of effort or whether the increment in force depends on the level of voluntary effort. Isometric force matching tasks were performed under different combinations of voluntary effort and FES. Participants reached a steady level of force, and while attempting to maintain a constant effort level, FES was applied to augment the force. Results indicate that the increment in force produced by FES decreases as the level of initial voluntary effort increases. Potential mechanisms causing the change in force output are proposed, but the relative contribution of each mechanism is unknown.

  15. Will the global HIV response fail gay and bisexual men and other men who have sex with men?

    2016-11-01

    Full Text Available Introduction: Gay and bisexual men and other men who have sex with men are among the small number of groups for whom HIV remains uncontrolled worldwide. Although there have been recent and notable decreases in HIV incidence across several countries, prevalence and incidence is consistently higher or rising among men who have sex with men when compared with other groups. Methods: In 2014, MSMGF (the Global Forum on MSM & HIV conducted its third biennial Global Men's Health and Rights Study, an international, multilingual, web-based cross-sectional survey of men who have sex with men recruited through online convenience sampling. We tested hypothesized correlates (selected a priori of successfully achieving each step along the HIV prevention and treatment continuum by fitting separate generalized estimating equation models adjusted for clustering by country in multivariate analyses. All models controlled for ability to meet basic financial needs, age, healthcare coverage, having a regular provider, region and country-level income. Results: Higher provider discrimination and sexual stigma were associated with lower odds of perceived access to services, service utilization and virologic suppression. Conversely, accessing services from community-based organizations focused on lesbian, gay, bisexual and transgender people; greater engagement in gay community; and comfort with healthcare providers were associated with higher odds of achieving steps along the prevention and treatment continuum. Conclusions: To meet accelerated global HIV targets, global leaders must adopt a differentiated and bolder response, in keeping with current epidemiologic trends and community-based research. The HIV-related needs of gay and bisexual men and other men who have sex with men must be addressed openly, quickly and with sufficient resources to support evidence-based, community-led and human rights-affirming interventions at scale.

    2014-05-01

    Full Text Available Persons with an upper-limb amputation who use a body-powered prosthesis typically control the prehensor through contralateral shoulder movement, which is transmitted through a Bowden cable. Increased cable tension either opens or closes the prehensor; when tension is released, some passive element, such as a spring, returns the prehensor to the default state (closed or open. In this study, we used the Southampton Hand Assessment Procedure to examine functional differences between these two types of prehensors in 29 nondisabled subjects (who used a body-powered bypass prosthesis and 2 persons with unilateral transradial amputations (who used a conventional body-powered device. We also administered a survey to determine whether subjects preferred one prehensor or the other for specific tasks, with a long-term goal of assessing whether a prehensor that could switch between both modes would be advantageous. We found that using the voluntary closing prehensor was 1.3 s faster (p = 0.02 than using the voluntary opening prehensor, across tasks, and that there was consensus among subjects on which types of tasks they preferred to do with each prehensor type. Twenty-five subjects wanted a device that could switch between the two modes in order to perform particular tasks.

  17. Hedonic value of intentional action provides reinforcement for voluntary generation but not voluntary inhibition of action.

    Parkinson, Jim; Haggard, Patrick

    2013-12-01

    Intentional inhibition refers to stopping oneself from performing an action at the last moment, a vital component of self-control. It has been suggested that intentional inhibition is associated with negative hedonic value, perhaps due to the frustration of cancelling an intended action. Here we investigate hedonic implications of the free choice to act or inhibit. Participants gave aesthetic ratings of arbitrary visual stimuli that immediately followed voluntary decisions to act or to inhibit action. We found that participants for whom decisions to act produced a strong positive hedonic value for the immediately following visual stimulus made more choices to act than those with weaker hedonic value for action. This finding is consistent with reinforcement learning of action decisions. However, participants who experienced inhibition as generating more positive hedonic value did not choose to inhibit more than other participants. Thus, voluntary inhibition of action did not act as reinforcement for future inhibitory behaviour. Our finding that inhibition of action lacks motivational capacity may explain why self-control is both difficult and limited.

  19. MENX and MEN4

    Natalia S. Pellegata

    2012-01-01

    Full Text Available Multiple endocrine neoplasias are autosomal dominant disorders characterized by the occurrence of tumors in at least two endocrine glands. Two MEN syndromes have long been known and are well characterized: the MEN type 1 (MEN1 and type 2 (MEN2. These syndromes are caused by germline mutations in the MEN1 and RET genes, respectively, and have a different tumor spectrum. Recently, a variant of the MEN syndromes arose spontaneously in a rat colony and was named MENX. Affected animals consistently develop multiple endocrine tumors, with a spectrum that shares features with both MEN1 and MEN2 human syndromes. Genetic studies identified a germline mutation in the Cdkn1b gene, encoding the p27 cell cycle inhibitor, as the causative mutation for MENX. Capitalizing on these findings, heterozygous germline mutations in the human homologue, CDKN1B, were searched for and identified in patients with multiple endocrine tumors. As a consequence of this discovery, a novel human MEN syndrome, named MEN4, was recognized, which is caused by mutations in p27. Altogether, these studies identified Cdkn1b/CDKN1B as a novel tumor susceptibility gene for multiple endocrine tumors in both rats and humans. Here we review the characteristics of the MENX and MEN4 syndromes and we briefly address the main function of p27 and how they are affected by MENX/4-associated mutations.

    Recent studies of human arm movement have suggested that the control of stiffness may be important both for maintaining stability and for achieving differences in movement accuracy. In the present study, we have examined the voluntary control of postural stiffness in 3D in the human jaw. The goal is to address the possible role of stiffness control in both stabilizing the jaw and in achieving the differential precision requirements of speech sounds. We previously showed that patterns of kinematic variability in speech are systematically related to the stiffness of the jaw. If the nervous system uses stiffness control as a means to regulate kinematic variation in speech, it should also be possible to show that subjects can voluntarily modify jaw stiffness. Using a robotic device, a series of force pulses was applied to the jaw to elicit changes in stiffness to resist displacement. Three orthogonal directions and three magnitudes of forces were tested. In all conditions, subjects increased the magnitude of jaw stiffness to resist the effects of the applied forces. Apart from the horizontal direction, greater increases in stiffness were observed when larger forces were applied. Moreover, subjects differentially increased jaw stiffness along a vertical axis to counteract disturbances in this direction. The observed changes in the magnitude of stiffness in different directions suggest an ability to control the pattern of stiffness of the jaw. The results are interpreted as evidence that jaw stiffness can be adjusted voluntarily, and thus may play a role in stabilizing the jaw and in controlling movement variation in the orofacial system.

    Whereas the somatotopy of finger movements has been extensively studied with neuroimaging, the neural foundations of facial movements remain elusive. Therefore, we systematically studied the neuronal correlates of voluntary facial movements using the Facial Action Coding System (FACS, Ekman et al., 2002). The facial movements performed in the MRI scanner were defined as Action Units (AUs) and were controlled by a certified FACS coder. The main goal of the study was to investigate the detailed somatotopy of the facial primary motor area (facial M1). Eighteen participants were asked to produce the following four facial movements in the fMRI scanner: AU1+2 (brow raiser), AU4 (brow lowerer), AU12 (lip corner puller) and AU24 (lip presser), each in alternation with a resting phase. Our facial movement task induced generally high activation in brain motor areas (e.g., M1, premotor cortex, supplementary motor area, putamen), as well as in the thalamus, insula, and visual cortex. BOLD activations revealed overlapping representations for the four facial movements. However, within the activated facial M1 areas, we could find distinct peak activities in the left and right hemisphere supporting a rough somatotopic upper to lower face organization within the right facial M1 area, and a somatotopic organization within the right M1 upper face part. In both hemispheres, the order was an inverse somatotopy within the lower face representations. In contrast to the right hemisphere, in the left hemisphere the representation of AU4 was more lateral and anterior compared to the rest of the facial movements. Our findings support the notion of a partial somatotopic order within the M1 face area confirming the "like attracts like" principle (Donoghue et al., 1992). AUs which are often used together or are similar are located close to each other in the motor cortex.

    Movement-related cortical potentials (MRCPs) are negative potentials over the scalp, which gradually increase prior to voluntary movements, and might be applied to elucidate the cortical efferent function of the mandibular movements. We compared the MRCPs accompanying various mandibular movements to study the motor control mechanism underlying these movements. Electroencephalograms (EEGs) were recorded from 11 electrodes placed over the scalp (F3, Fz, F4, T3, C3, Cz, C4, T4, P3, Pz, and P4), according to the International 10-20 System, and electromyograms (EMGs) were obtained from surface electrodes over the masseter muscle and the anterior belly of the digastric muscle. Ten healthy subjects were requested to make brisk and self-paced mandibular movements in 4 different directions (mouth-opening and -closing, and left and right lateral movements). We obtained MRCPs by averaging the EEG, using the visually determined EMG onset as a trigger signal. In all the movements, a slowly increasing, bilaterally widespread negativity starting 1.5 to 2.0 sec before the EMG onset (Bereitschaftspotential, or BP proper) was observed, with the maximum over the vertex region. The negative slope (NS') occurred about 300 to 700 msec before the EMG onset. The cortical maps of BP/NS' (BP and NS' combined), immediately prior to the mouth-opening and closing, showed a symmetrical distribution, whereas that for the lateral movements showed a tendency of predominance over the hemisphere ipsilateral to the direction of the movement. BP/NS' amplitudes at the onset of movement differed significantly or tended to do so between open, close, and lateral movements, suggesting that MRCP recordings may thus provide a means to explore the role of the cerebral cortex in the control of mandibular movements.

  4. Voluntary organizations in development in South Asia.

    The governments of South Asian countries have become aware of the substantial role that nongovernment organizations (NGOs) or voluntary agencies can play in rural development and other nation building activities. Although private agencies cannot substitute for government programs, there is general consensus that NGOs use development funds more efficiently and innovatively than government programs. NGOs in Bangladesh, India, and Pakistan exemplify the influence these organizations have on development in South Asia. The Lutheran World Service in Bangladesh, a foreign origin NGO, has branched out from its original aim of providing relief and war rehabilitation to give skills training and technical assistance to the poor. The Bangladesh Rural Advancement Committee, an indigenous NGO, works for the well-being and self-reliance of the landless poor, those with very small farms, and women. NGOs in Bangladesh have been especially innovative in developing methods to encourage self-help, such as local organization and credit, which are often combined with training in practical skills, literacy, nutrition, and family planning. Present NGO activity in India is dominated by the Gandhian tradition. There is a potential conflict between the philosophy of the NGO's in terms of building on the people's felt needs from the bottom up and the tendency of government agencies to want to plan for the people. In Pakistan, the concept of development-oriented NGOs is recent and not yet strong, although the government has adopted a policy of routing funds from government and from bilateral donor agencies through NGOs in 2 areas--family planning and women's welfare. The chief limitation of NGOs is their scope, meaning that the major burden of the development process rests on government agencies.

    Full Text Available There is increased focus on HIV prevention with African men who report experiencing childhood sexual (CSA or physical abuse (CPA.To better understand the effects of a community-based intervention (Project Accept HPTN 043 on HIV prevention behaviors among men who report CSA or CPA experiences.Project Accept compared a community-based voluntary mobile counseling and testing (CBVCT intervention with standard VCT. The intervention employed individual HIV risk reduction planning with motivational interviewing in 34 African communities (16 communities at 2 sites in South Africa, 10 in Tanzania, and 8 in Zimbabwe. Communities were randomized unblinded in matched pairs to CBVCT or SVCT, delivered over 36 months. The post-intervention assessment was conducted using a single, cross-sectional random survey of 18-32 year-old community members (total N = 43,292. We analyzed the effect of the intervention on men with reported CSA or CPA across the African sites. Men were identified with a survey question asking about having experienced CSA or CPA across the lifespan. The effect of intervention on considered outcomes of the preventive behavior was statistically evaluated using the logistic regression models.Across the sites, the rates of CSA or CPA among men indicated that African men reflected the global prevalence (20% with a range of 13-24%. The statistically significant effect of the intervention among these men was seen in their increased effort to receive their HIV test results (OR 2.71; CI: (1.08, 6.82; P: 0.034. The intervention effect on the other designated HIV prevention behaviors was less pronounced.The effect of the intervention on these men showed increased motivation to receive their HIV test results. However, more research is needed to understand the effects of community-based interventions on this group, and such interventions need to integrate other keys predictors of HIV including trauma, coping strategies, and intimate partner violence.

    The endocannabinoid system serves many physiological roles, including in the regulation of energy balance, food reward, and voluntary locomotion. Signaling at the cannabinoid type 1 receptor has been specifically implicated in motivation for rodent voluntary exercise on wheels. We studied four replicate lines of high runner (HR) mice that have been selectively bred for 81 generations based on average number of wheel revolutions on days five and six of a six-day period of wheel access. Four additional replicate lines are bred without regard to wheel running, and serve as controls (C) for random genetic effects that may cause divergence among lines. On average, mice from HR lines voluntarily run on wheels three times more than C mice on a daily basis. We tested the general hypothesis that circulating levels of endocannabinoids (i.e., 2-arachidonoylglycerol [2-AG] and anandamide [AEA]) differ between HR and C mice in a sex-specific manner. Fifty male and 50 female mice were allowed access to wheels for six days, while another 50 males and 50 females were kept without access to wheels (half HR, half C for all groups). Blood was collected by cardiac puncture during the time of peak running on the sixth night of wheel access or no wheel access, and later analyzed for 2-AG and AEA content by ultra-performance liquid chromatography coupled to tandem mass spectrometry. We observed a significant three-way interaction among sex, linetype, and wheel access for 2-AG concentrations, with females generally having lower levels than males and wheel access lowering 2-AG levels in some but not all subgroups. The number of wheel revolutions in the minutes or hours immediately prior to sampling did not quantitatively predict plasma 2-AG levels within groups. We also observed a trend for a linetype-by-wheel access interaction for AEA levels, with wheel access lowering plasma concentrations of AEA in HR mice, while raising them in C mice. In addition, females tended to have higher AEA

    The UN Population Fund contends that it is the need for family planning (FP) information and services instead of lack of interest that prevents men from participating more in FP. 3 pilot projects in Pakistan, Zimbabwe, and Colombia have acted on this belief. In geographically isolated Mardan, Pakistan, the all male Urban Community Developing Council (UCDC) started a community education project to involve men in FP. 5 UCDC member form 1 community educator team of which there are 60. The teams visit families in Mardan. In 1988, 1 team reported that some men in the households wanted a women to inform their wives about FP. Eventually UCDC located enough women free to be members on 40 teams. In 4 years, contraceptive prevalence among married couples rose from 9% to 21%. Initially the methods tended to be temporary methods but are now longer lasting methods (IUDs, sterilization, injectables, and even a few vasectomies). Other community groups donate about US$541/month to the project. In 1988, the Zimbabwean National Family Planning Council (ZNFPC) began its national education/male motivation project which included sending messages via popular radio soap opera, discussions, and leaflet distribution. The program reached many rural men since they tend to have radios. In 1 year, more men were taking part in decisions about FP (25-35%). ZNFPC has learned it needs to design 2 campaigns to promote condom use: 1 for single and 1 for married men. PROFAMILIA in Colombia began its 1st male clinic in 1985 in Bogota. By 1992, it had 8 male clinics. The key to its success is attractive clinics, low cost vasectomy, individualized care, wide range of services such as condom distribution and treatment of sexually transmitted diseases, and Saturday hours. Despite the 3 projects' successes, they face many obstacles that need to be addressed.

    Full Text Available Background: Voluntary counseling and testing (VCT is an important preventive strategy in the control of HIV/AIDS and Long distance truck drivers (LDTD have been identified as an important group in the transmission of HIV/AIDS. This study aims to assess knowledge and perception of Nigerian long distance truck drivers on HIV/AIDS, voluntary counseling and testing and their willingness to undergo HIV screening. Materials and Methods: One hundred and ninety seven LDTD in Enugu, Nigeria were surveyed using pre tested structured questionnaires. Results: Awareness of HIV/AIDS was high (94.9% amongst the drivers and the media was their commonest source of information. Similarly the awareness of VCT was high (94.4%. One hundred and eight (54.8% respondents were willing to undergo HIV screening test if offered freely and 86 (43.7% others have previously been screened. Educational status was a significant determinant of willingness to undergo HIV screening p<0.05. The reasons for screening were mainly doctors′ recommendation (19.3% and voluntary self screening (18.8%. The commonest reasons for not wanting to undergo screening were the feeling of not being at risk (27.9%, fear of a positive result (10.2% and cost of screening test (9.6%. Conclusion: There is a critical need to improve HIV screening participation amongst Long distance drivers in Nigeria.

    Full Text Available Objective: To identify issues related to topics such as maternity, pregnancy, voluntary abortion and women’s health from the perspective of Brazilian and African immigrants living in Portugal. Methods: This is an exploratory and descriptive study with a qualitative approach, held in Portugal between May and June 2008, with 35 immigrant women (from Brazil and the Portuguese-speaking African countries - Lusophone Africa or PALOP. Information was collected through a sociodemographic questionnaire and focus group conduction. Data was analyzed according to the common procedure of content analysis. Two categories of analysis emerged: 1 Pregnancy and Maternity and 2 Voluntary Abortion. Results: The research included 15 Brazilian and 20 African, aged between 21 and 45 years. Brazilian participants refer to possess higher educational level compared to African women. In general, both women go through various difficulties regarding issues involving pregnancy, maternity and voluntary abortion, especially sociocultural differences faced by the country in which they live. Conclusion: It is necessary the adoption of a social model of positive health, focused on the individuals’ and the population needs and, as far as possible, adapted to their specificities. In this sense, it is relevant that models are developed to promote the immigrant participation in the development of actions for health promotion in this area. doi:http://dx.doi.org/10.5020/18061230.2013.p470

    Full Text Available Background. Regular exercise at moderate intensity reduces cardiovascular risks. Matrix metalloproteinases (MMPs play a major role in cardiac remodeling, facilitating physiological adaptation to exercise. The aim of this study was to examine the influence of voluntary physical exercise on the MMP-2 enzyme activity and to investigate the cardiac performance by measurement of angina susceptibility of the heart, the basal blood pressure, the surviving aorta ring contraction, and the cardiac infarct size after I/R-induced injury. Methods. Male Wistar rats were divided into control and exercising groups. After a 6-week period, the serum level of MMP-2, basal blood pressure, cardiac angina susceptibility (the ST segment depression provoked by epinephrine and 30 s later phentolamine, AVP-induced heart perfusion and aorta ring contraction, infarct size following 30 min ischemia and 120 min reperfusion, and coronary effluent MMP-2 activity were measured. Results. Voluntary wheel-running exercise decreased both the sera (64 kDa and 72 kDa and the coronary effluent (64 kDa MMP-2 level, reduced the development of ST depression, improved the isolated heart perfusion, and decreased the ratio of infarct size. Conclusion. 6 weeks of voluntary exercise training preserved the heart against cardiac injury. This protective mechanism might be associated with the decreased activity of MMP-2.

    The Act provides the skeleton of the voluntary remediation program; the rules are the muscles and sinew necessary to make the program work. The Act sets an ambitious schedule of one year for developing all the rules needed to implement the program. Recognizing the difficulty of putting together a complex program, especially the technical standards, in such a short period of time, the Director convened a Steering Committee consisting of representatives of industry, government and environmental groups, and the general public, to develop an initial set of draft rules. The rules were proposed shortly before the 1997 Regular Session of the West Virginia Legislature convened. The ultimate impact of West Virginia`s new voluntary remediation program must await the adoption of implementing rules and experience under the program. The Act contains the essential components for an effective program, including protection from liability, certainty in remediation cleanup standards and recognition of the concept of relative risk in developing those standards. With a cohesive set of rules and an aggressive posture by the Director in implementing the program consistent with the goals of the Act, West Virginia could be a leader in the country in voluntary remediation programs.

    Full Text Available Impairment in social interactions is a primary characteristic of people diagnosed with autism spectrum disorder (ASD. Although these individuals tend to orient less to naturalistic social cues than do typically developing (TD individuals, laboratory experiments testing social orienting in ASD have been inconclusive, possibly because of a failure to fully isolate reflexive (stimulus-driven and voluntary (goal-directed social orienting processes. The purpose of the present study was to separately examine potential reflexive and/or voluntary social orienting differences in individuals with ASD relative to TD controls. Subjects (ages 7-14 with high-functioning ASD and a matched control group completed three gaze cueing tasks on an iPad in which individuals briefly saw a face with averted gaze followed by a target after a variable delay. Two tasks were 100% predictive with either all congruent (target appears in gaze direction or all incongruent (target appears opposite from gaze direction trials, respectively. Another task was non-predictive with these same trials (half congruent and half incongruent intermixed randomly. Response times (RTs to the target were used to calculate reflexive (incongruent condition RT – congruent condition RT and voluntary (non-predictive condition RT – predictive condition RT gaze cueing effects. Subjects also completed two additional non-social orienting tasks (ProPoint and AntiPoint. Subjects with ASD demonstrate intact reflexive but deficient voluntary gaze following. Similar results were found in a separate test of non-social orienting. This suggests problems with using social cues, but only in a goal-directed fashion, in our sample of high-functioning individuals with ASD. Such findings may not only explain inconclusive previous findings but more importantly be critical for understanding social dysfunctions in ASD and for developing future interventions.

    HIV testing in prison settings has been identified as an important mechanism to detect cases among high-risk, underserved populations. Several public health organizations recommend that testing across health-care settings, including prisons, be delivered in an opt-out manner. However, implementation of opt-out testing within prisons may pose challenges in delivering testing that is informed and understood to be voluntary. In a large state prison system with a policy of voluntary opt-out HIV testing, we randomly sampled adult prisoners in each of seven intake prisons within two weeks after their opportunity to be HIV tested. We surveyed prisoners' perception of HIV testing as voluntary or mandatory and used multivariable statistical models to identify factors associated with their perception. We also linked survey responses to lab records to determine if prisoners' test status (tested or not) matched their desired and perceived test status. Thirty-eight percent (359/936) perceived testing as voluntary. The perception that testing was mandatory was positively associated with age less than 25 years (adjusted relative risk [aRR]: 1.45, 95% confidence interval [CI]: 1.24, 1.71) and preference that testing be mandatory (aRR: 1.81, 95% CI: 1.41, 2.31) but negatively associated with entry into one of the intake prisons (aRR: 0.41 95% CI: 0.27, 0.63). Eighty-nine percent of prisoners wanted to be tested, 85% were tested according to their wishes, and 82% correctly understood whether or not they were tested. Most prisoners wanted to be HIV tested and were aware that they had been tested, but less than 40% understood testing to be voluntary. Prisoners' understanding of the voluntary nature of testing varied by intake prison and by a few individual-level factors. Testing procedures should ensure that opt-out testing is informed and understood to be voluntary by prisoners and other vulnerable populations.

    Bisexual men (men who have sex with men and women) are potential epidemiological bridges responsible for the spread of HIV and other sexually transmitted infections from men who have sex with men only to the heterosexual population. We aimed to estimate the prevalence of syphilis and HIV and the factors associated with syphilis infection among men who have sex with men and women and men who have sex with men only from Shijiazhuang, China. In 2011-2013, a cross-sectional cohort of 427 men who have sex with men was recruited by a snowball sampling method and tested for syphilis and HIV. Chi square and logistic regression were performed to identify syphilis risk factors. Among the 427 men who have sex with men, 71 (16.6%) cases were syphilis-positive and 16 cases (3.7%) were HIV-positive. The proportions of men who have sex with men and women and men who have sex with men only in the total sample were 31.4% and 68.6%, respectively. Men who have sex with men and women exhibited double the syphilis prevalence of men who have sex with men only and were more likely to practice insertive anal sex. Higher education level, being married, having more male partners, and both receptive and insertive anal sex roles were associated with syphilis among men who have sex with men and women. Residing in suburban areas, being married, being HIV positive, and an absence of desire to change sexual orientation were associated with syphilis among men who have sex with men only. Therefore, men who have sex with men and women represent an important sub-group in the syphilis epidemic and further interventions should be developed to reduce risk among different sub-sets of men who have sex with men.

    Historically, in France, cancer associations have been managed by doctors. Despite this, the French healthcare system has increasingly encouraged them to attract voluntary helpers who are not health workers. This development has given rise to the question of the competence and legitimacy of voluntary workers in cancer associations. The aim of the present study was to identify the skills possessed by voluntary helpers who have survived the disease and the extent to which their skills meet the needs of cancer associations in responding to the demands that have emerged in this new context. This is a qualitative study based on data collected during semi-directed interviews, focus group sessions and on-site observations in a variety of French cancer associations. Categorical and thematic analyses were then carried out separately for each ethnographic method used. The study showed that because the commitment of survivor voluntary helpers derives from their own experience of the disease, it is inconsistent with the fulfilment of the association's collective aims, such as the search for funding or project development. These helpers nevertheless play an important role that involves a special link between the individual and the group, between the community and society. To conclude, "involved" volunteers have to reconcile their individual expectations with the association's collective aims.

  3. Redefining RECs: Additionality in the voluntary Renewable Energy Certificate market

    Science.gov (United States)

    Gillenwater, Michael Wayne

    In the United States, electricity consumers are told that they can "buy" electricity from renewable energy projects, versus fossil fuel-fired facilities, through participation in a voluntary green power program. The marketing messages communicate to consumers that their participation and premium payments for a green label will cause additional renewable energy generation and thereby allow them to claim they consume electricity that is absent pollution as well as reduce pollutant emissions. Renewable Energy Certificates (RECs) and wind energy are the basis for the majority of the voluntary green power market in the United States. This dissertation addresses the question: Do project developers respond to the voluntary REC market in the United States by altering their decisions to invest in wind turbines? This question is investigated by modeling and probabilistically quantifying the effect of the voluntary REC market on a representative wind power investor in the United States using data from formal expert elicitations of active participants in the industry. It is further explored by comparing the distribution of a sample of wind power projects supplying the voluntary green power market in the United States against an economic viability model that incorporates geographic factors. This dissertation contributes the first quantitative analysis of the effect of the voluntary REC market on project investment. It is found that 1) RECs should be not treated as equivalent to emission offset credits, 2) there is no clearly credible role for voluntary market RECs in emissions trading markets without dramatic restructuring of one or both markets and the environmental commodities they trade, and 3) the use of RECs in entity-level GHG emissions accounting (i.e., "carbon footprinting") leads to double counting of emissions and therefore is not justified. The impotence of the voluntary REC market was, at least in part, due to the small magnitude of the REC price signal and lack of

    Climate change mitigation in developing economies is a balancing act, between economic development and environmental sustainability. The need for market friendly determinants for low carbon economy, without compromising economic development is of essence. The aim of the study is to determine market friendly factors, which motivates voluntary carbon information disclosure, in the real estate industry. The study modeled economic factor with three variables and financial market factor with three variables against voluntary carbon information disclosure in the real estate industry. Structural equation modeling was used for the modeling and content analysis was used to collect data on the level of voluntary carbon information disclosure, from 2013 annual reports of 126 real estate sector companies listed in the Kuala Lumpur Stock Exchange (KLSE). The model achieved a good fit, and was acceptable prediction. The results show that financial market factor has a significant predictive influence on voluntary carbon disclosure. The application of the result is that financial market factor is has a significantly positive influence on companies’ willingness to make voluntary carbon disclosure in the real estate industry. The result may be limited to the real estate industry that is highly leveraged on syndicated fund.

    The aim of this cross-sectional study was to concurrently assess musculo-articular stiffness (MAS) and muscle stiffness (MS) of the knee extensors in younger and older individuals. Fourteen young (22.1 ± 3.0 years old) and 12 older (65.4 ± 5.7 years old) men were tested for maximal voluntary contraction (MVC), rate of torque development (RTD), muscle thickness, MAS, and MS of knee extensors. MVC, RTD, and muscle thickness were higher in the younger group (288.6 vs. 194.3 Nm, 1319.5 vs. 787.0 Nm s(-1), 23.1 vs. 17.7 mm, respectively, P < 0.05). MAS normalized to the load supported (30% of MVC) was not different between groups (87.9 vs. 88.5 Nm(-1) kg(-1)), whereas the older group exhibited a higher level of normalized MS (23.2 vs. 18.6 Nm(-1) kg(-1), P < 0.05). Determinants of MS have been highlighted along with their role in elevated MS. The unaltered level of MAS, which is functionally important in an aging population, might be achieved through a decrease in tendon stiffness. Copyright © 2012 Wiley Periodicals, Inc.

    In most societies, heterosexuality is the dominant way of expressing sexuality and masculinity and those men outside of it are stigmatised and discriminated against. This paper explores the sexual lives of men who have sex with men and the personal and social conflicts that arise as they attempt to both live up to societal expectations and manage their sexual desires. It critically explores how an overriding heteronormativity structures and influences men's perception and understanding of sexuality and masculinity/femininity. The paper draws on data from 24 in-depth/life history interviews, one focus group discussion and ethnographic observation conducted between July 2006 and June 2007. The study reveals that powerful and dominating beliefs about heteronormativity and masculinity result in men who have sex with men dealing with a number of issues of personal conflict and contradiction resulting in uncertainty, resentment, ambivalence, worry and discomfort. Heteronormativity or the expectations of parents, community and society at large is far more influential on the sexuality of men who have sex with men than their own individual desires and needs. The paper concludes that there is little room for individuality for Ethiopian men who have sex with men with their sexual bodies 'belonging' to parents, families and to society at large.

    It is well known that voluntary running can enhance synaptic plasticity and improve learning and memory abilities. The Notch1 receptor is also reported to be associated with these processes, but its role in running-induced alterations is unclear. In this study, we aimed to investigate whether the Notch1 signalling pathway was involved in voluntary running-induced enhancement of synaptic plasticity, learning and memory. Notch1 heterozygous deficient (Notch1(+/-)) mice and wildtype (WT) C57BL littermates were randomly divided into runner group and non-runner group. Mice were given free access to running wheels for 14 days in both the Notch1(+/-) runner group and the WT runner group. Our results demonstrate that Notch1 knockdown impairs the performance in the novel object recognition (NOR) test and Morris water maze test and decreases the synaptic plasticity. Voluntary running improves spatial learning and memory abilities, promotes synaptic plasticity and increases expressions of postsynaptic proteins in WT mice but not in Notch1(+/-) mice. Our results suggest that Notch1 plays a vital role in spatial learning and memory, synaptic plasticity under normal physiological conditions and voluntary running conditions. These findings will set the groundwork and fill in some gaps for understanding the role of Notch1 signalling in voluntary running-induced phenomena.

  11. Neurons controlling voluntary vocalization in the macaque ventral premotor cortex.

    Directory of Open Access Journals (Sweden)

    Gino Coudé

    Full Text Available The voluntary control of phonation is a crucial achievement in the evolution of speech. In humans, ventral premotor cortex (PMv and Broca's area are known to be involved in voluntary phonation. In contrast, no neurophysiological data are available about the role of the oro-facial sector of nonhuman primates PMv in this function. In order to address this issue, we recorded PMv neurons from two monkeys trained to emit coo-calls. Results showed that a population of motor neurons specifically fire during vocalization. About two thirds of them discharged before sound onset, while the remaining were time-locked with it. The response of vocalization-selective neurons was present only during conditioned (voluntary but not spontaneous (emotional sound emission. These data suggest that the control of vocal production exerted by PMv neurons constitutes a newly emerging property in the monkey lineage, shedding light on the evolution of phonation-based communication from a nonhuman primate species.

  12. Suicide and voluntary active euthanasia: why the difference in attitude?

    1995-06-01

    It appears that the attitudes of health professionals differ towards suicide and voluntary active euthanasia. An acceptance of, if not an agreement with, voluntary active euthanasia exists, while there is a general consensus that suicide should be prevented. This paper searches for a working definition of suicide, to discover ethical reasons for the negative value that suicide assumes, and also to provide a term of reference when comparing suicide with euthanasia. On arriving at a working definition of suicide, it is compared with voluntary active euthanasia. An analysis of utilitarian and deontological considerations is provided and proves to be inconclusive with respect to the ethical principles informing the attitudes of professionals. Therefore, a search for other influences is attempted; this indicates that psychological influences inform attitudes to a greater degree than ethical principles.

    Full Text Available Health-related quality of life (HRQOL has become commonly used both as a concept and as a field of research. However, little is known about the HRQOL of men who have sex with men and women (MSMW. The aim of this study was to examine HIV-related behaviors, social support, and HRQOL status and explore its predictors among MSMW.An anonymous cross-sectional study was conducted by snowball sampling method in 2013. A total of 563 Chinese MSM completed a structured questionnaire. The HRQOL and social support were measured with the Chinese version of the World Health Organization Quality of Life Scale (WHOQOL-BRFE and the Social Support Rating Scale (SSRS, respectively.Of the 563 MSM analyzed, 77 (13.68% were MSMW who had a higher proportion of in-marriage and preference for an insertive role as compared with the men who have sex with men only (MSMO (P<0.05. As high as 70.13% of MSMW had no regular sex partners and 72.73% of MSMW reported engaging in unprotected anal sex in the last six months. 36.36% had tested for HIV, while only 12.99% had accepted HIV voluntary counseling and testing (VCT services. The scores of objective support and subjective support in MSMW were significantly higher than that of MSMO (P<0.05. No statistically significant difference was found in scores of all the four domains of the HRQOL between MSMW and MSMO. When comparing the HRQOL scores of MSMW with the Chinese general population reference group, the scores of MSMW were significantly lower in physical health domain. In a multivariate regression model, age, monthly income, sexual role, VCT acceptability, subjective support were associated with variability in HRQOL.To improve the HRQOL among MSMW, more attention needs to be paid to those with low social support, low-income, the old and those prefer a receptive role during anal sex populations.

    Full Text Available Not only animals, plants and microbes but also humans cooperate in groups. The evolution of cooperation in a group is an evolutionary puzzle, because defectors always obtain a higher benefit than cooperators. When people participate in a group, they evaluate group member's reputations and then decide whether to participate in it. In some groups, membership is open to all who are willing to participate in the group. In other groups, a candidate is excluded from membership if group members regard the candidate's reputation as bad. We developed an evolutionary game model and investigated how participation in groups and ostracism influence the evolution of cooperation in groups when group members play the voluntary public goods game, by means of computer simulation. When group membership is open to all candidates and those candidates can decide whether to participate in a group, cooperation cannot be sustainable. However, cooperation is sustainable when a candidate cannot be a member unless all group members admit them to membership. Therefore, it is not participation in a group but rather ostracism, which functions as costless punishment on defectors, that is essential to sustain cooperation in the voluntary public goods game.

This Voluntary Release Assessment/Corrective Action (RA/CA) report has been prepared for final submittal to the Environmental protection Agency (EPA) Region 6, Hazardous Waste Management Division and the New Mexico Environment Department (NMED) Hazardous and Radioactive Materials Bureau to describe the results of voluntary release assessment sampling and proposed corrective actions at the SWMU sites. The Voluntary RA/CA Program is intended to be the first phase in implementing the Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) and corrective action process at the WIPP. Data generated as part of this sampling program are intended to update the RCRA Facility Assessment (RFA) for the WIPP (Assessment of Solid Waste Management Units at the Waste Isolation Pilot Plant), NMED/DOE/AIP 94/1. This Final Voluntary RA/CA Report documents the results of release assessment sampling at 11 SWMUs identified in the RFA. With this submittal, DOE formally requests a No Further Action determination for these SWMUs. Additionally, this report provides information to support DOE`s request for No Further Action at the Brinderson and Construction landfill SWMUs, and to support DOE`s request for approval of proposed corrective actions at three other SWMUs (the Badger Unit Drill Pad, the Cotton Baby Drill Pad, and the DOE-1 Drill Pad). This information is provided to document the results of the Voluntary RA/CA activities submitted to the EPA and NMED in August 1995.

  19. Voluntary Participation in Regional Fisheries Management Council Meetings

    2010-09-01

    Full Text Available Insufficient and unrepresentative participation in voluntary public hearings and policy discussions has been problematic since Aristotle's time. In fisheries, research has shown that involvement is dominated by financially resourceful and extreme-opinion stakeholders and tends to advantage groups that have a lower cost of attendance. Stakeholders may exhibit only one or all of these traits but can be still similarly advantaged. The opposites of these traits tend to characterize the disadvantaged, such as the middle-ground opinions, the less wealthy or organized, and the more remote stakeholders. Remoteness or distance is the most straightforward and objective of these characteristics to measure. We analyzed the New England Fishery Management Council's sign-in sheets for 2003–2006, estimating participants' travel distance and associations with the groundfish, scallop, and herring industries. We also evaluated the representativeness of participation by comparing attendance to landings and permit distributions. The distance analysis showed a significant correlation between attendance levels and costs via travel distance. These results suggest a potential bias toward those stakeholders residing closer to meeting locations, possibly disadvantaging parties who are further and must incur higher costs. However, few significant differences were found between the actual fishing industry and attendee distributions, suggesting that the geographical distribution of the meeting attendees is statistically similar to that of the larger fishery. The interpretation of these results must take into consideration the limited time span of the analysis, as policy changes may have altered the industry make-up and location prior to our study. Furthermore, the limited geographical input of stakeholders may lend bias to the Council's perception of ecological and social conditions throughout the spatial range of the fishery. These factors should be further considered in

    Full Text Available OBJECTIVE: Voluntary HIV counseling and testing are provided to all Brazilian pregnant women with the purpose of reducing mother-to-child HIV transmission. The purpose of the study was to assess characteristics of HIV testing and identify factors associated with HIV counseling and testing. METHODS: A cross-sectional study was carried out comprising 1,658 mothers living in Porto Alegre, Brazil. Biological, reproductive and social variables were obtained from mothers by means of a standardized questionnaire. Being counseling about HIV testing was the dependent variable. Confidence intervals, chi-square test and hierarchical logistic model were used to determine the association between counseling and maternal variables. RESULTS: Of 1,658 mothers interviewed, 1,603 or 96.7% (95% CI: 95.7-97.5 underwent HIV testing, and 51 or 3.1% (95% CI: 2.3-4.0 were not tested. Four (0.2% refused to undergo testing after counseling. Of 51 women not tested in this study, 30 had undergone the testing previously. Of 1,603 women tested, 630 or 39.3% (95% CI: 36.9-41.7 received counseling, 947 or 59.2% (95% CI: 56.6-61.5 did not, and 26 (1.6% did not inform. Low income, lack of prenatal care, late beginning of prenatal care, use of rapid testing, and receiving prenatal in the public sector were variables independently associated with a lower probability of getting counseling about HIV testing. CONCLUSIONS: The study findings confirmed the high rate of prenatal HIV testing in Porto Alegre. However, women coming from less privileged social groups were less likely to receive information and benefit from counseling.

    Waste siting gridlock in the United States and Canada has led to experimentation with voluntary and hybrid or ``mixed mode`` siting. We review nuclear and hazardous waste voluntary siting (VS) results for selected cases in the U.S, and Canada. Findings indicate that VS is not a panacea, but that current siting efforts are inadequate tests of its potential. We suggest trials of improved VS protocols and more effort on hybrid approaches in which the developer chooses the site but is required to reach agreement on conditions with local stakeholders. Mixed mode siting may be better suited to the US context and its three-tiered governmental system.

    We investigated adults' voluntary control of 20 facial action units theoretically associated with 6 basic emotions (happiness, fear, anger, surprise, sadness, and disgust). Twenty young adults were shown video excerpts of facial action units and asked to reproduce them as accurately as possible. Facial Action Coding System (FACS; Ekman & Friesen, 1978a) coding of the facial productions showed that young adults succeeded in activating 18 of the 20 target actions units, although they often coactivated other action units. Voluntary control was clearly better for some action units than for others, with a pattern of differences between action units consistent with previous work in children and adolescents.

    Remote voluntary contractions (RVCs) are described as a muscle action of the prime mover while performing a simultaneous muscle action with another part of the body. Previous studies have shown that RVCs may elicit augmented performance of the prime mover. The purpose of this study was to evaluate the effect of RVCs on knee extensor rate of velocity development (RVD) and peak torque. Fourteen men and 16 women who were regularly active and free of any knee pathology for the past year took part in this study. Subjects performed 3 maximal dynamic knee extensions at 3 velocities with and without an RVC condition. The RVC condition consisted of holding hand dynamometers in each hand and maximally gripping while performing a maximal knee extension movement. The NO-RVC condition was the same only without gripping. Men produced greater peak torque and RVD than did women across speeds and conditions. Analysis demonstrated that RVC had no effect on knee extension peak torque, but RVD decreased in the RVC condition (NO-RVC 2,012.07 [46.52] degrees xs-1xs-1; RVC 1,882.61 [51.84] degrees xs-1xs-1). Grip strength of the left hand at 180 degrees xs-1decreased from 42.03 (14.40) to 38.83 (14.65) kg in the RVC condition. In conclusion, RVC should not be used when attempting to maximize RVD, because it may hinder results when performing a single joint movement.

    Full Text Available In the past gender specific problems were mainly discussed in a female perspective. In the meantime there is a rising attentiveness in the living conditions of men and their coping strategies within critical life events. In this paper an appropriate frame of reference is outlined which can be used in those areas of social work where men are already discovered as a target group with special difficulties and needs.

    While psychological conflict about dependency needs of alcoholic and obese persons has been widely observed, few studies have examined differences in dependency characteristics between these clinical groups. The Interpersonal Dependency Inventory was administered to 22 alcoholic and 8 morbidly obese men in intensive treatment for alcohol and obesity. The original hypothesis that alcoholic and obese men would show similar dependency needs was supported. Dependency correlates of personality may serve as useful predictor variables in the clinical treatment of alcoholic and obese persons.

    Full Text Available This paper provides a new way to identify conditional cooperation in a real-time version of the standard voluntary contribution mechanism. We define contribution cycles as the number of contributors a player waits for before committing to a further contribution, and use a permutation test on contribution cycles to assign a measure of conditional cooperation to each group play. The validity of the measures is tested in an experiment. We find that roughly 20% of the plays exhibit dynamics of conditional cooperation. Moreover, notwithstanding a decline in contributions, conditional cooperation is found to be stable over time.

    The purpose of this study was to investigate the effects of 8weeks at 6g per day of RAR CLA versus placebo on cognitive function and handgrip performance in older men and women. Sixty-five (43 women, 22 men) participants (mean±SD; age=72.4±5.9yrs; BMI=26.6±4.2kg·m(-2)) were randomly assigned to a RAR CLA (n=30: 10 men, 20 women) or placebo (PLA; high oleic sunflower oil; n=35: 12 men, 23 women) group in double-blind fashion and consumed 6g·d(-1) of their allocated supplement for 8weeks. Before (Visit 1) and after supplementation (Visit 2), subjects completed the Serial Sevens Subtraction Test (S7), Trail Making Test Part A (TMA) and Part B (TMB), and Rey's Auditory Verbal Learning Test (RAVLT) to measure cognitive function. The RAVLT included 5, 15-item auditory word recalls (R1-5), an interference word recall (RB), a 6th word recall (R6), and a 15-item visual word recognition trial (RR). For handgrip performance, subjects completed maximal voluntary isometric handgrip strength (MVIC) testing before (MVICPRE) and after (MVICPOST) a handgrip fatigue test at 50% MVICPRE. Hand joint discomfort was measured during MVICPRE, MVICPOST, and the handgrip fatigue test. There were no treatment differences (p>0.05) for handgrip strength, handgrip fatigue, or cognitive function as measured by the Trail Making Test and Serial Seven's Subtraction Test in men or women. However, RAR CLA supplementation improved cognitive function as indicated by the RAVLT R5 in men. A qualitative examination of the mean change scores suggested that, compared to PLA, RAR CLA supplementation was associated with a small improvement in joint discomfort in both men and women. Longer-term studies are needed to more fully understand the potential impact of RAR CLA on cognitive function and hand joint discomfort in older adults, particularly in those with lower cognitive function.

    Men with body dysmorphic disorder (BDD) may be preoccupied with the size or shape of the penis, which may be causing significant shame or impairment. Little is known about the characteristics and phenomenology of such men and whether they can be differentiated from men with small penis anxiety (SPA) (who do not have BDD), and men with no penile concerns. Twenty-six men with BDD, 31 men with SPA, and 33 men without penile concerns were compared on psychopathology, experiences of recurrent imagery, avoidance and safety-seeking behaviours. Men with BDD had significantly higher scores than both the SPA group and no penile concern group for measures of imagery, avoidance, safety seeking and general psychopathology. The groups differed on the phenomenology of BDD specific to penile size preoccupation clearly from the worries of SPA, which in turn were different to those of the men without concerns. The common avoidance and safety seeking behaviours were identified in such men that may be used clinically.

  17. Towards a gender perspective in qualitative research on voluntary medical male circumcision in east and southern Africa.

    The World Health Organization endorsed voluntary medical male circumcision (VMMC) in 2007 as an effective method to provide partial protection against heterosexual female-to-male transmission of HIV in regions with high rates of such transmission, and where uptake of VMMC is low. Qualitative research conducted in east and southern Africa has focused on assessing acceptability, barriers to uptake of VMMC and the likelihood of VMMC increasing men's adoption of risky sexual behaviours. Less researched, however, have been the perceptions of women and sexual minorities towards VMMC, even though they are more vulnerable to HIV/AIDS transmission than are heterosexual men. The purpose of this paper is to identify core areas in which a gendered perspective in qualitative research might improve the understanding and framing of VMMC in east and southern Africa. Issues explored in this analysis are risk compensation, the post-circumcision appearance of the penis, inclusion of men who have sex with men as study respondents and the antagonistic relation between VMMC and female genital cutting. If biomedical and social science researchers explore these issues in future qualitative inquiry utilising a gendered perspective, a more thorough understanding of VMMC can be achieved, which could ultimately inform policy and implementation.

  20. For men only.

    Science.gov (United States)

    1993-01-01

    In 1985 the Colombian Family Planning Association PROFAMILIA realized that men did not want to come to its family planning centers simply because they felt intimidated by the feminine atmosphere there. Nor did they dare disclose their problems and sexual questions even to a female professional. The solution was to establish a family planning center, La Clinica del Hombre (Men's Clinic), providing services exclusively for men and staffed with men to provide the necessary privacy. Latin American men's attitudes are changing. In 1985 in Bogota, the majority of men were convinced that a vasectomy was equivalent to castration. In 1993, 300 vasectomies were performed in the clinic each month. The Colombian Family Planning Association is not only providing contraception, but also information on sexual and reproductive education to avoid misunderstanding of the available methods. PROFAMILIA has incorporated a sexuality consultation into its services, so they can deal with husbands and wives separately, without spoiling the couple's relationship. PROFAMILIA now has 7 family planning clinics for men and 48 for women, thanks to the contribution of international donors. The Challenge Grant for Men's Programs, given by an anonymous donor from the United States, helped with the fund-raising to open 3 clinics in the Atlantic Coast Region where needs were vital. The Clinica del Hombre will incorporate a program to treat infertility, in addition to the department of urology, general medicine, ambulatory surgery, and treatment of sexually transmitted diseases. In January, 1994, they will begin offering dental and plastic surgery services because, owing to the violence that exists in the country, there are many men whose faces are disfigured and who need to have corrective plastic surgery.

    There is a high prevalence of childhood sexual abuse and HIV among Latino gay men, with limited proven HIV prevention interventions. This study used qualitative methods to explicate earlier findings showing differential health outcomes among Latino gay men who had no sex, voluntary, or forced sex before age 16. Analyses of in-depth interviews with 27 Latino gay men revealed that structural factors in childhood contribute to their developing sexuality by enhancing or inhibiting a sense of agency. Agency is essential for making decisions that are in line with their intentions to have healthy sexual lives. Findings suggest that interventions should focus on developing a sense of sexual agency among Latino gay men by (a) increasing their recognition of structural factors that contribute to feelings of worthlessness in order to relocate internalized blame and homophobia to external structural forces, (b) facilitating awareness of the social structural oppressions that lead to psychological and sexual risk in order to enhance their options for sexual health, and (c) shifting from individually focused constructions of sexual health to those that consider the structural factors that reduce agency and contribute to diminished sexual health among Latino gay men.

  2. Handgrip Maximal Voluntary Isometric Contraction Does Not Correlate with Thenar Motor Unit Number Estimation

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available In slowly progressive conditions, such as motor neurone disease (MND, 50–80% of motor units may be lost before weakness becomes clinically apparent. Despite this, maximal voluntary isometric contraction (MVIC has been reported as a clinically useful, reliable, and reproducible measure for monitoring disease progression in MND. We performed a study on a group of asymptomatic subjects that showed a lack of correlation between isometric grip strength and thenar MUNE. Motor unit number estimation (MUNE estimates the number of functioning lower motor neurones innervating a muscle or a group of muscles. We used the statistical electrophysiological technique of MUNE to estimate the number of motor units in thenar group of muscles in 69 subjects: 19 asymptomatic Cu, Zn superoxide dismutase 1 (SOD 1 mutation carriers, 34 family controls, and 16 population controls. The Jamar hand dynamometer was used to measure isometric grip strength. This study suggests that MUNE is more sensitive for monitoring disease progression than maximal voluntary isometric contraction (MVIC, as MUNE correlates with the number of functional motor neurones. This supports the observation that patients with substantial chronic denervation can maintain normal muscle twitch tension until 50–80% of motor units are lost and weakness is detectable.

    It is well-established that exercise can influence psychological conditions, cognitive function, and energy metabolism in peripheral tissues including the skeletal muscle. However, it is not clear whether exercise can influence social interaction with others and alleviate defeat stress. This study investigated the effect of voluntary wheel running on impaired social interaction induced by chronic social defeat stress (SDS) using the resident-intruder social defeat model. Mice were divided into three groups: control, stress alone, and stress+exercise. SDS was performed by exposing C57BL/6 mice to retired ICR mice for 2.5 min. The C57BL/6 mice were continuously defeated by these resident (aggressor) mice and, following 5 days of SDS, experienced 2 days of rest with no SDS. Mice in the stress+exercise group were allowed to voluntarily run on a wheel for 2h after every SDS exposure. Two weeks later, compared to the control group, the stress group showed a higher ratio of time spent in the corner zone of a social interaction paradigm even though SDS did not elicit depressive- and anxiety-like behaviors. We also observed that voluntary exercise, which did not affect muscle weight and gene expression, decreased social avoidance behavior of stressed mice without clear changes in brain monoamine levels. Interestingly, food intake in the stress+exercise group was the greatest among the three groups. To test the effect of the exercise-induced increase in food intake on social behavior, we set up a pair-fed group where food intake was restricted. We then compared these mice to mice in the stress alone group. We found that the ratio of time spent in the corner zone of the social interaction test was not different between ad libitum- and pair-fed groups, although pair-fed mice spent more time in the corner zone when an aggressor mouse was present than when it was absent. In addition, pair-feeding did not show exercise-induced reductions of adrenal gland weight and enhanced the

    Full Text Available In order to attract more promising young people to join the military and enhance combat capability, Taiwan’s Department of Defense is transforming the nation’s military service system from a draft system, which has been in effect for more than sixty years, to an all-volunteer military force system. The government hopes that the new system not only can recruit promising voluntary soldiers, but that they also continue their military service after the contract expires in order to ensure stability in recruitment sources. This study explores the intention of voluntary soldiers to continue their military service. This study’s questionnaire encompasses five dimensions: Participation motivation, organization commitment, career planning, personality traits and departure tendency. The questionnaires were issued to 350 voluntary soldiers to explore if they intend to continue their service after their contract expires, with a total of 314 effective questionnaires that were recovered and analyzed. The results find that about half of the voluntary soldiers indicate that they do not plan on staying and continuing their service after contract expiration, which will result in understaffing in the military. In order to stabilize the prescribed number of soldiers, the existing recruiting policy and military management system should be re-adjusted.

  15. Voluntary imitation in Alzheimer’s disease patients

    Directory of Open Access Journals (Sweden)

    Ambra eBisio

    2016-03-01

    Full Text Available Although Alzheimer's disease (AD primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients’ behaviour. The aim of the present study was to investigate whether voluntary motor imitation, i.e. a volitional mechanism that involves observing another person’s action and translating this perception into one’s own action, was affected in patients with Alzheimer’s disease. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

    2010-02-01

    Full Text Available Abstract Background Electrodermal reactions (EDRs can be attributed to many origins, including spontaneous fluctuations of electrodermal activity (EDA and stimuli such as deep inspirations, voluntary mental activity and startling events. In fields that use EDA as a measure of psychophysiological state, the fact that EDRs may be elicited from many different stimuli is often ignored. This study attempts to classify observed EDRs as voluntary (i.e., generated from intentional respiratory or mental activity or involuntary (i.e., generated from startling events or spontaneous electrodermal fluctuations. Methods Eight able-bodied participants were subjected to conditions that would cause a change in EDA: music imagery, startling noises, and deep inspirations. A user-centered cardiorespiratory classifier consisting of 1 an EDR detector, 2 a respiratory filter and 3 a cardiorespiratory filter was developed to automatically detect a participant's EDRs and to classify the origin of their stimulation as voluntary or involuntary. Results Detected EDRs were classified with a positive predictive value of 78%, a negative predictive value of 81% and an overall accuracy of 78%. Without the classifier, EDRs could only be correctly attributed as voluntary or involuntary with an accuracy of 50%. Conclusions The proposed classifier may enable investigators to form more accurate interpretations of electrodermal activity as a measure of an individual's psychophysiological state.

    The decision to participate in a research intervention or to undergo medical treatment should be both informed and voluntary. The aim of the present study was to develop an instrument to measure the perceived voluntariness of parents making decisions for their seriously ill children. A total of 219 parents completed questionnaires within 10 days of making such a decision at a large, urban tertiary care hospital for children. Parents were presented with an experimental form of the Decision Making Control Instrument (DMCI), a measure of the perception of voluntariness. Data obtained from the 28-item form were analyzed using a combination of both exploratory and confirmatory factor analytic techniques. The 28 items were reduced to 9 items representing 3 oblique dimensions: Self-Control, Absence of Control, and Others' Control. The hypothesis that the 3-factor covariance structure of our model was consistent with that of the data was supported. Internal consistency for the scale as a whole was high (0.83); internal consistency for the subscales ranged from 0.68 to 0.87. DMCI scores were associated with measures of affect, trust, and decision self-efficacy, supporting the construct validity of the new instrument. The DMCI is an important new tool that can be used to inform our understanding of the voluntariness of treatment and research decisions in medical settings.

  13. Selection and inhibition mechanisms for human voluntary action decisions.

    Zhang, Jiaxiang; Hughes, Laura E; Rowe, James B

    One can choose between action alternatives that have no apparent difference in their outcomes. Such voluntary action decisions are associated with widespread frontal-parietal activation, and a tendency to inhibit the repetition of a previous action. However, the mechanism of initiating voluntary actions and the functions of different brain regions during this process remains largely unknown. Here, we combine computational modeling and functional magnetic resonance imaging to test the selection and inhibition mechanisms that mediate trial-to-trial voluntary action decisions. We fitted an optimized accumulator model to behavioral responses in a finger-tapping task in which participants were instructed to make chosen actions or specified actions. Model parameters derived from each individual were then applied to estimate the expected accumulated metabolic activity (EAA) engaged in every single trial. The EAA was associated with blood oxygenation level-dependent responses in a decision work that was maximal in the supplementary motor area and the caudal anterior cingulate cortex, consistent with a competitive accumulation-to-threshold mechanism for action decision by these regions. Furthermore, specific inhibition of the previous action's accumulator was related to the suppression of response repetition. This action-specific inhibition correlated with the activity of the right inferior frontal gyrus, when the option to repeat existed. Our findings suggest that human voluntary action decisions are mediated by complementary processes of intentional selection and inhibition.

  17. Chronic intermittent toluene inhalation initiated during adolescence in rats does not alter voluntary consumption of ethanol in adulthood.

    Science.gov (United States)

    Dick, Alec L W; Lawrence, Andrew J; Duncan, Jhodie R

    2014-09-01

    Voluntary inhalation of organic solvents, such as toluene, is particularly prevalent in adolescent populations and is considered to be a contributing factor to substance use and dependence later in life. While inhalants are often the initial "drug" experienced during this period, alcohol is another substance readily abused by adolescent populations. Although both substances are thought to have similar actions within the brain, our understanding of the implications of adolescent inhalant abuse upon subsequent exposure to alcohol remains to be investigated. Thus, this study aimed to assess locomotor responses to acute ethanol and voluntary ethanol consumption following a period of toluene inhalation throughout adolescence/early adulthood. Adolescent male Wistar rats (postnatal day [PN] 27) inhaled air or toluene (3000 ppm) for 1 h/day, 3 days/week for 4 (PN 27-52) or 8 weeks (PN 27-80) to mimic the patterns observed in human inhalant abusers. Following the exposure period, cross-sensitization to acute ethanol challenge (0.5 g/kg, intra-peritoneally [i.p.]), and voluntary consumption of 20% ethanol in a chronic intermittent 2-bottle choice paradigm, were assessed. Hepatic ethanol and acetaldehyde metabolism and liver histopathology were also investigated. Chronic intermittent toluene (CIT) exposure throughout adolescence for up to 8 weeks did not alter the behavioral response to acute ethanol or voluntary consumption of ethanol in adulthood, although an age-dependent effect on ethanol consumption was observed (p<0.05). Both liver function and pathology did not differ between treatment groups. Thus, in the paradigm employed, CIT exposure throughout adolescence and early adulthood did not predispose rats to subsequent locomotor sensitivity or voluntary consumption of ethanol in adulthood.

  1. A difference in hypothalamic structure between heterosexual and homosexual men.

    Science.gov (United States)

    LeVay, S

    1991-08-30

    The anterior hypothalamus of the brain participates in the regulation of male-typical sexual behavior. The volumes of four cell groups in this region [interstitial nuclei of the anterior hypothalamus (INAH) 1, 2, 3, and 4] were measured in postmortem tissue from three subject groups: women, men who were presumed to be heterosexual, and homosexual men. No differences were found between the groups in the volumes of INAH 1, 2, or 4. As has been reported previously, INAH 3 was more than twice as large in the heterosexual men as in the women. It was also, however, more than twice as large in the heterosexual men as in the homosexual men. This finding indicates that INAH is dimorphic with sexual orientation, at least in men, and suggests that sexual orientation has a biological substrate.

  2. HPV Infection in Men

    Directory of Open Access Journals (Sweden)

    Joel M. Palefsky

    2007-01-01

    Full Text Available While much is known about the natural history of cervical human papillomavirus (HPV infection and its consequences, including cervical intraepithelial neoplasia and cervical cancer, relatively little is known about the natural history of anogenital HPV infection and diseases in men. In part this reflects difficulties in penile sampling and visual assessment of penile lesions. Anal HPV infection and disease also remain poorly understood. Although HPV is transmitted sexually and infects the genitals of both sexes, the cervix remains biologically more vulnerable to malignant transformation than does the penis or anus in men. An understanding of male HPV infection is therefore important in terms of reducing transmission of HPV to women and improving women's health. However, it is also important due to the burden of disease in men, who may develop both penile and anal cancer, particularly among HIV-positive men who have sex with men. Improved sampling techniques of the male genitalia and cohort studies in progress should provide important information on the natural history of anogenital HPV infection and disease in men, including risk factors for HPV acquisition and transmission. The impact of HPV vaccination in women on male anogenital HPV infection will also need to be assessed.

  12. Reduced Cognitive-Motor Interference on Voluntary Balance Control in Older Tai Chi Practitioners.

    Science.gov (United States)

    Varghese, Rini; Hui-Chan, Christina W Y; Bhatt, Tanvi

    2016-01-01

    Recent dual-task studies suggest that Tai Chi practitioners displayed better control of standing posture and maintained a quicker response time of postural muscle activation during a stepping down activity. Whether this effect extends to voluntary balance control, specifically the limits of excursion of the center of pressure, remains to be examined. The purpose of this study was to evaluate the cognitive-motor interference pattern by examining the effects of a concurrently performed cognitive task on attention of voluntary balance control in older adults who are long-term practitioners of Tai Chi. Ten older Tai Chi practitioners and 10 age-matched nonpractitioners performed a voluntary balance task that required them to shift their weight to reach a preset target in the forward and backward directions, with (single task, ST) and without (dual task, DT) a secondary cognitive task, which was the counting backward task. The counting backward task required the individual to compute and verbalize a series of arithmetic differences between a given pair of randomly generated numbers. The cognitive task was also performed independently (cognitive-ST). All trials were performed in a random order. Balance outcomes included reaction time, movement velocity, and maximal excursion of the center of pressure provided by the NeuroCom system. Cognitive outcome was the number of correct responses generated within the 8-second trial during the ST and DT conditions. Outcome variables were analyzed using a 2-factor, group by task, analysis of variance. DT costs for the variables were calculated as the relative difference between ST and DT conditions and were compared between the 2 groups using independent t tests. Tai Chi practitioners displayed shorter reaction times (P motor and cognitive resources than older nonpractitioners during a fairly complex (dynamic) postural equilibrium task while performing a verbal working memory task. They exhibited lesser cognitive-motor interference

  14. Speech and Pause Characteristics Associated with Voluntary Rate Reduction in Parkinson’s disease and Multiple Sclerosis

    Science.gov (United States)

    Tjaden, Kris; Wilding, Greg

    2011-01-01

    The primary purpose of this study was to investigate how speakers with Parkinson’s disease (PD) and Multiple Sclerosis (MS) accomplish voluntary reductions in speech rate. A group of talkers with no history of neurological disease was included for comparison. This study was motivated by the idea that knowledge of how speakers with dysarthria voluntarily accomplish a reduced speech rate would contribute toward a descriptive model of speaking rate change in dysarthria. Such a model has the potential to assist in identifying rate control strategies to receive focus in clinical treatment programs and also would advance understanding of global speech timing in dysarthria. All speakers read a passage in Habitual and Slow conditions. Speech rate, articulation rate, pause duration, and pause frequency were measured. All speaker groups adjusted articulation time as well as pause time to reduce overall speech rate. Group differences in how voluntary rate reduction was accomplished were primarily one of quantity or degree. Overall, a slower-than-normal rate was associated with a reduced articulation rate, shorter speech runs that included fewer syllables, and longer more frequent pauses. Taken together, these results suggest that existing skills or strategies used by patients should be emphasized in dysarthria training programs focusing on rate reduction. Results further suggest that a model of voluntary speech rate reduction based on neurologically normal speech shows promise as being applicable for mild to moderate dysarthria. PMID:21767851

  15. Sperm DNA damage in men from infertile couples

    Institute of Scientific and Technical Information of China (English)

    Juris Erenpreiss; Saad Elzanaty; Aleksander Giwercman

    2008-01-01

    Aim: To investigate the prevalence of high levels of sperm DNA damage among men from infertile couples with both normal and abnormal standard semen parameters. Methods: A total of 350 men from infertile couples were assessed. Standard semen analysis and sperm chromatin structure assay (SCSA) were carried out. Results: Ninety-seven men (28% of the whole study group) had a DNA fragmentation index (DFI) > 20%, and 43 men (12%) had a DFI > 30%. In the group of men with abnormal semen parameters (n = 224), 35% had a DFI > 20%, and 16% had a DFI > 30%, whereas these numbers were 15% and 5%, respectively, in the group of men with normal semen parameters (n = 126). Men with low sperm motility and abnormal morphology had significantly higher odds ratios (Ors) for having a DFI > 20% (4.0 for motility and 1.9 for morphology) and DFI > 30% (6.2 for motility and 2.8 for morphology) compared with men with normal sperm motility and morphology. Conclusion: In almost one-third of unselected men from infertile couples, the DFI exceeded the level of 20% above which, according to previous studies, the in vivo fertility is reduced. A significant proportion of men with otherwise normal semen parameters also had high sperm DNA damage levels. Thus, the SCSA test could add to explaining causes of infertility in cases where semen analysis has not shown any deviation from the norm. We also recommend running the SCSA test to choose the appropriate assisted reproductive technique (ART).

    Full Text Available Abstract Background Prostate cancer that has recurred after local therapy or disseminated distantly is usually treated with androgen deprivation therapy; however, most men will eventually experience disease progression within 12 to 20 months. New data emerging from randomized controlled trials (RCTs of chemotherapy provided the impetus for a systematic review addressing the following question: which non-hormonal systemic therapies are most beneficial for the treatment of men with hormone-refractory prostate cancer (HRPC and clinical evidence of metastases? Methods A systematic review was performed to identify RCTs or meta-analyses examining first-line non-hormonal systemic (cytotoxic and non-cytotoxic therapy in patients with HRPC and metastases that reported at least one of the following endpoints: overall survival, disease control, palliative response, quality of life, and toxicity. Excluded were RCTs of second-line hormonal therapies, bisphosphonates or radiopharmaceuticals, or randomized fewer than 50 patients per trial arm. MEDLINE, EMBASE, the Cochrane Library, and the conference proceedings of the American Society of Clinical Oncology were searched for relevant trials. Citations were screened for eligibility by four reviewers and discrepancies were handled by consensus. Results Of the 80 RCTs identified, 27 met the eligibility criteria. Two recent, large trials reported improved overall survival with docetaxel-based chemotherapy compared to mitoxantrone-prednisone. Improved progression-free survival and rates of palliative and objective response were also observed. Compared with mitoxantrone, docetaxel treatment was associated with more frequent mild toxicities, similar rates of serious toxicities, and better quality of life. More frequent serious toxicities were observed when docetaxel was combined with estramustine. Three trials reported improved time-to-disease progression, palliative response, and/or quality of life with mitoxatrone

  17. Changing dynamics in the Canadian voluntary sector: challenges in sustaining organizational capacity to support healthy communities.

    Science.gov (United States)

    Steedman, Eric; Rabinowicz, Jane

    2006-11-01

    The voluntary sector is recognized, by citizens, industry and government, as an increasingly vital contributor to healthy communities within Canadian society, called upon to provide front-line service delivery in areas of community support that were in the past often served by government and or religious charity. (The voluntary sector is large, consisting of an estimated 180,000 non-profit organizations [of which 80,000 are registered as charities] and hundreds of thousands more volunteer groups that are not incorporated [Statistics Canada, 2002].) The dynamics of the sector have changed considerably over the past decade, as government has pulled back the level of core organizational funding support and the role of the church has diminished. As community health is directly related to the organizational health of service-providing non-profits and charities, these organizations are looking increasingly towards corporate and individual donors, along with new self-financing approaches that generate revenues. They are also facing challenges in attracting and retaining skilled and motivated volunteers. As the scope of the voluntary sector and its overall influence grows, so do the organizational and financial challenges it faces. This article will address in particular the issue of funding support for healthy communities and examine a number of potential and existing best practices for sustaining community health in Canada. We will also look at the issue of volunteerism and human resource capacity challenges for organizations. This is an area in which the Canadian government has decided to focus as a result of explicit policy decisions taken in the late 1990s.

  18. Voluntary exercise contributed to an amelioration of abnormal feeding behavior, locomotor activity and ghrelin production concomitantly with a weight reduction in high fat diet-induced obese rats.

    Mifune, Hiroharu; Tajiri, Yuji; Nishi, Yoshihiro; Hara, Kento; Iwata, Shimpei; Tokubuchi, Ichiro; Mitsuzono, Ryouichi; Yamada, Kentaro; Kojima, Masayasu

    2015-09-01

    In the present study, effects of voluntary exercise in an obese animal model were investigated in relation to the rhythm of daily activity and ghrelin production. Male Sprague-Dawley rats were fed either a high fat diet (HFD) or a chow diet (CD) from four to 16 weeks old. They were further subdivided into either an exercise group (HFD-Ex, CD-Ex) with a running wheel for three days of every other week or sedentary group (HFD-Se, CD-Se). At 16 weeks old, marked increases in body weight and visceral fat were observed in the HFD-Se group, together with disrupted rhythms of feeding and locomotor activity. The induction of voluntary exercise brought about an effective reduction of weight and fat, and ameliorated abnormal rhythms of activity and feeding in the HFD-Ex rats. Wheel counts as voluntary exercise was greater in HFD-Ex rats than those in CD-Ex rats. The HFD-obese had exhibited a deterioration of ghrelin production, which was restored by the induction of voluntary exercise. These findings demonstrated that abnormal rhythms of feeding and locomotor activity in HFD-obese rats were restored by infrequent voluntary exercise with a concomitant amelioration of the ghrelin production and weight reduction. Because ghrelin is related to food anticipatory activity, it is plausible that ghrelin participates in the circadian rhythm of daily activity including eating behavior. A beneficial effect of voluntary exercise has now been confirmed in terms of the amelioration of the daily rhythms in eating behavior and physical activity in an animal model of obesity.

    Aim: To evaluate the efficacy and safety of SK3530, a newly developed type 5 phosphodiesterase inhibitor (PDE5I), in Korean men with erectile dysfunction (ED). Methods: A total of 119 patients were randomized at 10 centers in Korea to receive either SK3530 (50, 100, or 150 mg; n = 89) or placebo (n = 30) taken 1 h before anticipated sexual activity for an 8-week period. The patients were evaluated at baseline and 4 and 8 weeks after beginning therapy. Efficacy was assessed using the International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP), and the Global Assessment Question (GAQ). Safety was analyzed by adverse events, laboratory values and vital signs. Results: At the end of the study, all the primary and secondary efficacy end-points were statistically significantly improved by SK3530 compared with placebo (P < 0.05). Of the 89 patients in the treatment arm, 36 (42.3 %) achieved normal erectile mfunction after treatment, including six patients with severe ED. Treatment-related adverse events occurred in 32 patients.The most common adverse events were flushing, headache, dizziness and eye redness (10.9%, 7.6%, 2.5% and 2.5%, respectively), and most were mild. Only two patients discontinued treatment during the study period because of adverse events. Conclusion: The results of our phase Ⅱ study have confirmed the efficacy and safety of SK3530 in a broad population of men with ED of various etiologies and severity. The optimal doses in terms of efficacy and safety were determined to be 50 mg and 100 mg, respectively.

    Knowledge about drug use and its association with HIV risk among men who have sex with men is limited. Although the HIV epidemic among this population in Vietnam is increasingly acknowledged, understanding the impact of drug use on the spread of HIV is largely lacking. Using qualitative data from in-depth interviews and focus group discussions with 93 drug users, 15 non-drug users and 9 community stakeholders, this analysis explores emerging patterns of drug use and risk factors for engaging in risk behaviours among drug-using men having sex with men, men selling sex and transgender individuals in Hanoi and Ho Chi Minh City. Findings revealed that drug use is shifting from heroin to ecstasy and ice. Drug users reported unsafe sex associated with drug use and men selling sex were particularly at elevated risk because of using drugs as a tool for sex work and trading sex for drugs. These findings are guiding development of programmes addressing unmet HIV-prevention needs in Vietnam.

    Full Text Available Background: Chromosomal abnormalities and Y chromosome microdeletions are regarded as two most frequent genetic causes associated with failure of spermatogenesis in the Caucasian population. Materials and Methods: To investigate the distribution of genetic defects in the Romanian population with azoospermia or severe oligozoospermia, karyotype analysis by G-banding was carried out in 850 idiopathic infertile men and in 49 fertile men with one or more children. Screening for microdeletions in the azoospermia factor (AZF region of Y chromosome was performed by multiplex polymerase chain reaction (PCR on a group of 67 patients with no detectable chromosomal abnormality. The results of the two groups were compared by a two-tailed Fisher’s exact test. Results: In our study chromosomal abnormalities were observed in 12.70% and 8.16% of infertile and fertile individuals respectively. Conclusion: Our data suggests that infertile men with severe azoospermia have higher incidences of genetic defects than fertile men and also patients from any other group. Infertile men with normal sperm present a higher rate of polymorphic variants. It is important to know whether there is a genetic cause of male infertility before patients are subjected to intracytoplasmic sperm injection (ICSI or testicular sperm extraction (TESE/ICSI treatment.

    The voluntary green power market refers to the sale and procurement of renewable energy for voluntary purposes by residential and commercial customers. This report reviews seven green power procurement mechanisms: utility green pricing programs, utility green tariffs, voluntary unbundled renewable energy certificates, competitive supplier green power, community choice aggregations, voluntary power purchase agreements (PPAs), and community solar. This report details the status of trends of those seven green power procurement mechanisms in 2015. Three trends -- significant growth of the voluntary PPA project pipeline, innovative green power mechanisms developed by utilities, and geographic expansion of green power mechanisms -- suggest that the green power market is likely to continue to grow in coming years.

  3. Benefits of voluntary industry standards: The triumph of experience over regulation

    Voluntary international standards for mining machinery may gradually replace many national regulations. The days of establishing voluntary standards nation by nation, inhibiting the important flow of international trade, could be numbered. This does not mean that nations will cease domestic regulatory activities within their boundaries, but rulemaking will pay considerable attention to voluntary international standards and will likely strive for compatibility with voluntary international standards. International standards setting bodies are developing standards for machine safety. When these standards are complete and adopted, some nations will require machinery to comport with them. International commerce in products that do not conform to these voluntary international standards may be discouraged.

    In the USA, HIV-positive Black men who have sex with men show large disparities in disease outcomes compared to other racial/ethnic and risk groups. This study examined the strategies that HIV-positive Black men who have sex with men use to cope with different types of discrimination. A total of 27 HIV-positive Black men who have sex with men participated in semi-structured interviews, which were transcribed verbatim and coded using thematic analysis by multiple raters. Major coping themes included reactive avoidance (using behaviours, cognitions and emotions to escape from discrimination), a common reaction to racism; proactive avoidance (avoiding situations in which discrimination is anticipated), manifested as selective disclosure of HIV-serostatus; external attribution for discrimination (versus self-blame), used more for sexual orientation and HIV discrimination; and social support-seeking, which most often emerged in response to racism. Active coping strategies, such as self-advocacy (countering discrimination directly or indirectly), were infrequently reported. Findings suggest a need for structural anti-discrimination interventions, in tandem with culturally congruent individual- or group-level interventions that aim to enhance men's existing adaptive coping strategies.

    China faces a significant challenge in the years ahead to continue to provide essential materials and products for a rapidly-growing economy while addressing pressing environmental concerns. China's industrial sector is heavily dependent on the country's abundant, yet polluting, coal resources. While tremendous energy conservation and environmental protection achievements were realized in the industrial sector in the past, there remains a great gulf between the China's level of energy efficiency and that of the advanced countries of the world. Internationally, significant energy efficiency improvement in the industrial sector has been realized in a number of countries using an innovative policy mechanism called Voluntary Agreements. This paper describes international experience with Voluntary Agreements in the industrial sector as well as the development of a pilot program to test the use of such agreements with two steel mills in Shandong Province, China.

    Involuntary autobiographical memories are conscious memories of personal events that come to mind with no preceding attempts at retrieval. It is often assumed that such memories are closely related to current concerns - i.e., uncompleted personal goals. Here we examined involuntary versus voluntary...... (deliberately retrieved) autobiographical memories in relation to earlier registered current concerns measured by the Personal Concern Inventory (PCI; Cox & Klinger, 2000). We found no differences between involuntary and voluntary memories with regard to frequency or characteristics of current concern related...... contents. However, memories related to current concerns were rated as more central to the person's identity, life story and expectations for the future than non-concern related memories, irrespective of mode of recall. Depression and PTSD symptoms correlated positively with the proportion of current...

    This study assesses the issue of voluntary training of a standardized online competition (serious gaming) between surgical residents. Surgical residents were invited to join a competition on a virtual reality (VR) simulator for laparoscopic motor skills. A final score was calculated based on the task performance of three exercises and was presented to all the participants through an online database on the Internet. The resident with the best score would win a lap-top computer. During three months, 31 individuals from seven hospitals participated (22 surgical residents, 3 surgeons and six interns). A total of 777 scores were logged in the database. In order to out-perform others some participants scheduled themselves voluntarily for additional training. More attempts correlated with higher scores. The serious gaming concept may enhance voluntary skills training. Online data capturing could facilitate monitoring of skills progression in surgical trainees and enhance (VR) simulator validation.

    This study examines whether voluntary sleep restriction at commonly experienced levels impacts decision making in a Bayesian choice task. Participants recruited were largely traditional age college students from a regional state university (n = 100) and a federal military academy (n = 99; n = 56 and 43, respectively, used in final analysis). Sleep was measured by actigraphy over a one-week period, followed by performance of a decision task. The task involved two sources of information, base rate odds and sample evidence, with subjects asked to make a probability judgment. Results found that subjects with nightly sleep sleep deprived = SD), relative to those with > 7 hr, placed less decision weight on new evidence, relative to base rate information, in making difficult choices. This result is strongest among female subjects. For easier choices, voluntary SD did not affect relative decision weights placed on the two sources of available information.

    Although bilingual children frequently switch between languages, the psycholinguistic mechanisms underlying the emerging ability to control language choice are unknown. We examined the mechanisms of voluntary language switching in English-Spanish bilingual children during a picture-naming task under two conditions: 1) single-language naming in English and in Spanish; 2) either-language naming, when the children could use whichever language they wanted. The mechanism of inhibitory control was examined by analyzing local switching costs and global mixing costs. The mechanism of lexical accessibility was examined by analyzing the properties of the items children chose to name in their non-dominant language. The children exhibited significant switching costs across both languages and asymmetrical mixing costs; they also switched into their non-dominant language most frequently on highly accessible items. These findings suggest that both lexical accessibility and inhibition contribute to language choice during voluntary language switching in children. PMID:26889376

    This study investigated effects of plyometric training (6 weeks, 3 sessions/week) on maximum voluntary contraction (MVC) strength and neural activation of the knee extensors during isometric, concentric and eccentric contractions. Twenty-seven participants were randomly assigned to the intervention or control group. Maximum voluntary torques (MVT) during the different types of contraction were measured at 110° knee flexion (180°=full extension). The interpolated twitch technique was applied at the same knee joint angle during isometric, concentric and eccentric contractions to measure voluntary activation. In addition, normalized root mean square of the EMG signal at MVT was calculated. The twitch torque signal induced by electrical nerve stimulation at rest was used to evaluate training-related changes at the muscle level. In addition, jump height in countermovement jump was measured. After training, MVT increased by 20Nm (95% CI: 5-36Nm, P=0.012), 24Nm (95% CI: 9-40Nm, P=0.004) and 27Nm (95% CI: 7-48Nm, P=0.013) for isometric, concentric and eccentric MVCs compared to controls, respectively. The strength enhancements were associated with increases in voluntary activation during isometric, concentric and eccentric MVCs by 7.8% (95% CI: 1.8-13.9%, P=0.013), 7.0% (95% CI: 0.4-13.5%, P=0.039) and 8.6% (95% CI: 3.0-14.2%, P=0.005), respectively. Changes in the twitch torque signal of the resting muscle, induced by supramaximal electrical stimulation of the femoral nerve, were not observed, indicating no alterations at the muscle level, whereas jump height was increased. Given the fact that the training exercises consisted of eccentric muscle actions followed by concentric contractions, it is in particular relevant that the plyometric training increased MVC strength and neural activation of the quadriceps muscle regardless of the contraction mode.

    Voluntary activation levels during lengthening, isometric, and shortening contractions (angular velocity 60 degrees/s) were investigated by using electrical stimulation of the femoral nerve (triplet, 300 Hz) superimposed on maximal efforts. Recruitment of fiber populations was investigated by using the phosphocreatine-to-creatine ratio (PCr/Cr) of single characterized muscle fibers obtained from needle biopsies at rest and immediately after a series of 10 lengthening, isometric, and shortening contractions (1 s on/1 s off). Maximal voluntary torque was significantly higher during lengthening (270 +/- 55 N.m) compared with shortening contractions (199 +/- 47 N.m, P < 0.05) but was not different from isometric contractions (252 +/- 47 N.m). Isometric torque was higher than torque during shortening (P < 0.05). Voluntary activation level during maximal attempted lengthening contractions (79 +/- 8%) was significantly lower compared with isometric (93 +/- 5%) and shortening contractions (92 +/- 3%, P < 0.05). Mean PCr/Cr values of all fibers from all subjects at rest were 2.5 +/- 0.6, 2.0 +/- 0.7, and 2.0 +/- 0.7, respectively, for type I, IIa, and IIax fibers. After 10 contractions, the mean PCr/Cr values for grouped fiber populations (regardless of fiber type) were all significantly different from rest (1.3 +/- 0.2, 0.7 +/- 0.3, and 0.8 +/- 0.6 for lengthening, isometric, and shortening contractions, respectively; P < 0.05). The cumulative distributions of individual fiber populations after either contraction mode were significantly different from rest (P < 0.05). Curves after lengthening contractions were less shifted compared with curves from isometric and shortening contractions (P < 0.05), with a smaller shift for the type IIax compared with type I fibers in the lengthening contractions. The results indicate a reduced voluntary drive during lengthening contractions. PCr/Cr values of single fibers indicated a hierarchical order of recruitment of all fiber

    Full Text Available Background : Voluntary non-remunerated repeat blood donors are perceived to be safer than the first time blood donors. This study was planned for follow-up of previous hepatitis C virus (HCV test results of anti-HCV enzyme-linked immunosorbent assay (ELISA reactive repeat blood donors. The aim was to suggest a protocol for re-entry of the blood donors who are confirmed HCV negative by nucleic acid test (NAT and recombinant immunoblot assay (RIBA. A group of repeat voluntary donors were followed retrospectively who became reactive on a cross sectional study and showed HCV reactivity while donating blood regularly. Material and Methods: A total of 51,023 voluntary non remunerated blood donors were screened for anti-HCV ELISA routinely. If anybody showed positivity, they were tested by two ELISA kits (screening and confirmatory and then confirmed infection status by NAT and or RIBA. The previous HCV test results of repeat donors reactive by anti-HCV ELISA were looked back from the records. Data of donors who were repeat reactive with single ELISA kit (in the present study were analyzed separately from those reactive with two ELISA kits (in the present study. Results: In this study, 140 (0.27% donors who were reactive by anti HCV ELISA were included. Out of them, 35 were repeat voluntary donors and 16 (11.43% were reactive with single ELISA kit. All 16 donors were reactive by single ELISA kit occasionally in previous donations. Their present ELISA positive donations were negative for HCV NAT and RIBA. A total of 19 (13.57% donors were reactive with two ELISA kits. In their previous donations, the donors who were reactive even once with two ELISA kits were consistently reactive by the same two ELISA kits in their next donations also. Conclusion: Donor sample reactive by only single ELISA kit may not be considered as infectious for disposal as they were negative by NAT and or RIBA. One time ELISA positivity was found probably due to ELISA kit

    Full Text Available Certain theories suggest that it should be difficult or impossible to eradicate a vaccine-preventable disease under voluntary vaccination: Herd immunity implies that the individual incentive to vaccinate disappears at high coverage levels. Historically, there have been examples of declining coverage for vaccines, such as MMR vaccine and whole-cell pertussis vaccine, that are consistent with this theory. On the other hand, smallpox was globally eradicated by 1980 despite voluntary vaccination policies in many jurisdictions. Previous modeling studies of the interplay between disease dynamics and individual vaccinating behavior have assumed that infection is transmitted in a homogeneously mixing population. By comparison, here we simulate transmission of a vaccine-preventable SEIR infection through a random, static contact network. Individuals choose whether to vaccinate based on infection risks from neighbors, and based on vaccine risks. When neighborhood size is small, rational vaccinating behavior results in rapid containment of the infection through voluntary ring vaccination. As neighborhood size increases (while the average force of infection is held constant, a threshold is reached beyond which the infection can break through partially vaccinated rings, percolating through the whole population and resulting in considerable epidemic final sizes and a large number vaccinated. The former outcome represents convergence between individually and socially optimal outcomes, whereas the latter represents their divergence, as observed in most models of individual vaccinating behavior that assume homogeneous mixing. Similar effects are observed in an extended model using smallpox-specific natural history and transmissibility assumptions. This work illustrates the significant qualitative differences between behavior-infection dynamics in discrete contact-structured populations versus continuous unstructured populations. This work also shows how disease

    We perform a content analysis of twenty marriage and family textbooks published between 1950 and 2000 to study how the voluntarily childless are presented in undergraduate courses. Throughout the time period studied, independence, pursuit of a career, and romance were prominent themes in the representation of voluntary childlessness. Other themes emerged specific to each decade - the 1950s portrayed parenthood as a challenge, while the 1990s concentrated on alleviating negative stereotypes of the voluntarily childless.

    Full Text Available The aim of the study was to find whether voluntary induced high- and low-frequency peripheral fatigue exhibit specific alteration in surface EMG signal (SEMG during evoked and maximum voluntary contractions. Ten male students of physical education performed 60 s long stretch-shortening cycle (SSC exercise with maximal intensity and 30 s long concentric (CON exercise with maximal intensity. To verify voluntary induced peripheral fatigue, knee torques during low- (T20 and high-frequency electrical stimulation (T100 of relaxed vastus lateralis muscle (VL were obtained. Contractile properties of the VL were measured with passive twitch and maximal voluntary knee extension test (MVC. Changes in M-waves and SEMG during MVC test were used to evaluate the differences in myoelectrical signals. T100/T20 ratio decreased by 10.9 ± 8.4 % (p < 0.01 after the SSC exercise and increased by 35.9 ± 17.5 % (p < 0.001 after the CON exercise. Significant SEMG changes were observed only after the CON exercise where peak to peak time of the M-waves increased by 9.2 ± 13.3 % (p < 0.06, SEMG amplitude during MVC increased by 32.9 ± 21.6 % (p < 0.001 and SEMG power spectrum median frequency decreased by 11.0 ± 10.5 % (p < 0.05. It is concluded that high frequency fatigue wasn't reflected in SEMG, however the SEMG changes after the CON seemed to reflect metabolic changes due to acidosis
