    2014-01-01

    The health care literature describes treatment challenges and recommended alterations in practice procedures for female survivors of childhood sexual abuse, a subtype of adverse childhood experiences. Currently, there are no concomitant recommendations for best clinical practices for male survivors of childhood sexual abuse or other adverse clinical experiences. Anecdotal information suggests ways physicians can address the needs of adult male survivors of childhood sexual abuse by changes in communication, locus of control, and consent/permission before and during physical examinations and procedures. The intent of this article is to act as a catalyst for improved patient care and more research focused on the identification and optimal responses to the needs of men with adverse childhood experiences in the health care setting.

    The influence of the Wenchuan earthquake on semen quality of adult male survivors is unclear. We investigated the semen quality included 673 male survivors from the worse-affected counties in the earthquake between Aug 2008 and July 2013. Semen parameters including pH, volume, concentration, motility and morphology were measured according to the World Health Organization (WHO) criteria. Kruskal-Wallis analysis of variance was used to examine the statistical differences between years, and a logistic regression was used to analyse the impacts caused by earthquake on the changes of semen quality. We found the medians (5th and 95th) were 2.5 ml (0.6-5.5) for semen volume, 59.0 × 10(6)  ml(-1) [(13.0-133.0)] × 10(6)  ml(-1) for semen concentration, 46% (13-64%) for sperm progressive motility and 3.0% (0-17.5%) for normal morphology for adult male survivors. Semen concentration, the percentage of sperm progressive motility, total motility and sperm normal morphology were all decreased in the first 3 years, and the differences among years 1, 2 and 3 were significant except the percentage of sperm progressive motility (P < 0.05). The casualties and heavy housing damage caused by earthquake had a negative effect on semen quality. The main findings will provide further diagnosis and therapy basis of male fertility by data, for affected populations in the earthquake.

    Testicular size has been studied in 66 adult men who survived leukemia (n = 14) or cancer (n = 52) in childhood. Mean follow-up time was 14.5 years. The testicular size was measured as the length and breadth in mm; testicular volume index was calculated. Serum concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and prolactin were measured. A sperm sample was obtained from 46 men. The patients had smaller testicles than healthy medical students; 51 had small testicles. The size was the smallest in patients who survived leukemia. Multivariate analysis showed that the variables with independent effects on testicular size were cranial and testicular irradiation and therapy with cyclophosphamide. Sperm production was dependent on testicular size. We conclude that determination of serum FSH combined with testicular size may offer a practical approach for predicting the subsequent testicular damage in boys with malignancies.

  4. Survivorship: adult cancer survivors.

    During the next decade, a rapid increase in the number of new cancer diagnoses in the population as well as a growing number of cancer survivors can be expected. Cancer is anticipated to exceed cardiovascular disease as the primary cause of mortality in the United States population. Despite efforts in tobacco control, the aging of the population and obesity epidemic will contribute toward the increasing incidence of cancer. Although oncology specialists will continue to play a critical role in the diagnosis and initial treatment of patients with cancer, primary care providers will need to play an expanding role in the early detection of cancer, as well as the follow-up, health promotion, and cancer surveillance that will be necessary after initial cancer treatment. Oncology specialists will need to do a better job coordinating the care of their patients with primary care providers, and work toward a shared care model that will optimize the quality of care delivered by the health care system. Cancer treatment summaries and survivorship care plans are an initial attempt to address the current fragmentation and lack of coordination in care that exist today. Cancer survivors are at risk for a wide range of late effects after their primary cancer treatment. Unfortunately, there is limited information about the exact incidence and prevalence of many physical late effects. For example, how many women given standard adjuvant chemotherapy with doxorubicin and cyclophosphamide for breast cancer at age 35 years will develop permanent amenorrhea after treatment, and be infertile? What is the excess risk of osteoporosis in a 70-year-old man receiving endocrine therapy for prostate cancer? What is the risk of coronary artery disease after mantle irradiation for Hodgkin lymphoma? Because of the limited database for many of these sequelae of treatment, clinicians have to keep all of these potential risks in mind as they interview a survivor, and develop a long-term management plan

    2009-01-01

    Background Studies of sexuality or sexual behavior in childhood cancer survivors tend to examine relationships or achievement of developmental milestones but not physiological response to cancer or treatment. The purpose of this study is to (1) identify prevalence and risk factors for sexual dysfunction in childhood cancer survivors, and (2) examine the extent to which sexual dysfunction may be associated with health-related quality of life (HRQOL) and psychosocial outcomes. Methods Five hundred ninety-nine survivors age 18-39 years completed standardized measures of sexual functioning, HRQOL, psychological distress and life satisfaction. Descriptive statistics assessed prevalence of sexual symptoms. Bivariate analyses identified correlates of sexual symptoms and examined associations between symptoms and HRQOL/psychosocial outcomes. Results Most survivors appear to be doing well, although 52% of female survivors and 32% of male survivors reported at least “a little of a problem” in one or more areas of sexual functioning. Mean symptom score for females was more than twice that of males. Sexual symptoms were associated with reporting health problems. Significant associations between sexual functioning and HRQOL outcomes were observed, with gender differences in strengths of association suggesting that males find sexual symptoms more distressing than do females. Conclusions While most survivors appear to be doing well in this important life domain, some young adult survivors report sexual concerns. While female survivors may report more sexual symptoms than male survivors, males may experience more distress associated with sexual difficulties. Better specified measures of sexual function, behavior and outcomes are needed for this young adult population. PMID:19862693

    Purpose Survival rates for individuals diagnosed with retinoblastoma (RB) exceed 95% in the United States; however, little is known about the long-term psychosocial outcomes of these survivors. Patients and Methods Adult RB survivors, diagnosed from 1932 to 1994 and treated in New York, completed a comprehensive questionnaire adapted from the Childhood Cancer Survivor Study (CCSS), by mail or telephone. Psychosocial outcomes included psychological distress, anxiety, depression, somatization, fear of cancer recurrence, satisfaction with facial appearance, post-traumatic growth, and post-traumatic stress symptoms; noncancer CCSS siblings served as a comparison group. Results A total of 470 RB survivors (53.6% with bilateral RB; 52.1% female) and 2,820 CCSS siblings were 43.3 (standard deviation [SD], 11) years and 33.2 (SD, 8.4) years old at the time of study, respectively. After adjusting for sociodemographic factors, RB survivors did not have significantly higher rates of depression, somatization, distress, or anxiety compared with CCSS siblings. Although RB survivors were more likely to report post-traumatic stress symptoms of avoidance and/or hyperarousal (both P < .01), only five (1.1%) of 470 met criteria for post-traumatic stress disorder. Among survivors, having a chronic medical condition did not increase the likelihood of psychological problems. Bilateral RB survivors were more likely than unilateral RB survivors to experience fears of cancer recurrence (P < .01) and worry about their children being diagnosed with RB (P < .01). However, bilateral RB survivors were no more likely to report depression, anxiety, or somatic complaints than unilateral survivors. Conclusion Most RB survivors do not have poorer psychosocial functioning compared with a noncancer sample. In addition, bilateral and unilateral RB survivors seem similar with respect to their psychological symptoms. PMID:26417002

    Introduction Little is known about the impact of childhood cancer on the personal income of survivors. We compared income between survivors and siblings, and determined factors associated with income. Methods As part of the Swiss Childhood Cancer Survivor Study (SCCSS), a questionnaire was sent to survivors, aged ≥18 years, registered in the Swiss Childhood Cancer Registry (SCCR), diagnosed at age <21 years, who had survived ≥5 years after diagnosis of the primary tumor. Siblings were used as a comparison group. We asked questions about education, profession and income and retrieved clinical data from the SCCR. We used multivariable logistic regression to identify characteristics associated with income. Results We analyzed data from 1’506 survivors and 598 siblings. Survivors were less likely than siblings to have a high monthly income (>4’500 CHF), even after we adjusted for socio-demographic and educational factors (OR = 0.46, p<0.001). Older age, male sex, personal and parental education, and number of working hours were associated with high income. Survivors of leukemia (OR = 0.40, p<0.001), lymphoma (OR = 0.63, p = 0.040), CNS tumors (OR = 0.22, p<0.001), bone tumors (OR = 0.24, p = 0.003) had a lower income than siblings. Survivors who had cranial irradiation, had a lower income than survivors who had no cranial irradiation (OR = 0.48, p = 0.006). Discussion Even after adjusting for socio-demographic characteristics, education and working hours, survivors of various diagnostic groups have lower incomes than siblings. Further research needs to identify the underlying causes. PMID:27213682

    2010-04-01

    Male survivors of childhood sexual abuse face challenges resolving sexual victimization experiences with the ideals of masculinity, often experiencing intimacy problems, emotional discomfort, alienation, and anger. Little attention has been paid to how male survivors learn to develop long-term connections, disclose emotions in relationship contexts, and negotiate intimacy. The current qualitative study of 16 adult male survivors of childhood sexual abuse, examined the relational challenges and the processes by which these survivors improved their capacity for seeking and participating in supportive relationships over time. Several mechanisms associated with positive adaptation were identified in their narratives, including engaging in safe relationships; gaining a sense of belonging by locating a community of others with shared experiences; learning healthy ways to manage relationships through setting boundaries, controlling anger, building trust, and developing intimacy; and achieving acceptance. Clinical implications and future directions for research and intervention are presented.

  9. Effects of Child Sexual Abuse on the Parenting of Male Survivors.

    2016-10-21

    Research shows that child sexual abuse (CSA) can have detrimental effects on adult functioning. While much research regarding the effects of CSA on parenting of mothers is available, there is a dearth of information on how CSA impacts fatherhood. This literature review finds that the parenting experiences of male survivors are characterized by self-perceptions as adequate parents, deficient parenting as measured by standardized instruments, conceptualization of parenting as an intergenerational legacy and potential healing experience, fear of becoming an abuser, and physical and emotional distance from their children. These themes are strongly related to social discourses on intergenerational cycle of violence theories. Fatherhood is not exclusively problematic for male survivors and can be a healing experience and a source of strength for some survivors. Based on literature concerning male survivors who are parents, narrative therapy is recommended as a therapeutic model to explore how fathers who are survivors challenge dominant discourses around legacies of family violence, intergenerational parenting deficiencies, and victimization. Restorying fatherhood as a healing opportunity is essential when working with fathers who are male survivors and their families.

    Adult survivors of childhood brain tumors experience multiple, significant, lifelong deficits as a consequence of their malignancy and therapy. Current survivorship literature documents the substantial impact such impairments have on survivors' physical health and quality of life. Psychosocial reports detail educational, cognitive, and emotional limitations characterizing survivors as especially fragile, often incompetent, and unreliable in evaluating their circumstances. Anecdotal data suggest some survivors report life experiences similar to those of healthy controls. The aim of our investigation was to determine whether life satisfaction in adult survivors of childhood brain tumors differs from that of healthy controls and to identify potential predictors of life satisfaction in survivors. This cross-sectional study compared 78 brain tumor survivors with population-based matched controls. Chi-square tests, t tests, and linear regression models were used to investigate patterns of life satisfaction and identify potential correlates. Results indicated that life satisfaction of adult survivors of childhood brain tumors was similar to that of healthy controls. Survivors' general health expectations emerged as the primary correlate of life satisfaction. Understanding life satisfaction as an important variable will optimize the design of strategies to enhance participation in follow-up care, reduce suffering, and optimize quality of life in this vulnerable population.

    2016-01-01

    Purpose: Many adolescent and young adult (AYA) cancer survivors place great importance on fertility. This study explored AYAs' discussions of fertility in the context of discussing their survivorship experiences. Methods: Secondary analyses of a qualitative study of young adult survivors of adolescent cancers (“AYA survivors”) was performed using semistructured individual interviews and focus groups. Analyses were conducted using grounded theory using thematic content analysis with an inductive data-driven approach. Results: Participants (n = 43) were 16–24 years old, diagnosed with cancer between ages 14 and 18 years, and were at least 6 months post-treatment. Before treatment, 5 males banked sperm and no females preserved fertility. More males (50%) than females (39%) reported uncertainty about their fertility. Three major categories emerged from the data: fertility concerns, emotions raised when discussing fertility, and strategies used to manage fertility concerns. Fertility concerns focused on dating/partner reactions, health risks, and what potential infertility would mean for their life narrative. Emotions included distress, feeling overwhelmed and hopeful/wishful thinking. Females were more likely to feel distressed and overwhelmed than males. Strategies to manage concerns included acceptance/“making do,” desire to postpone concerns, and reliance on assisted reproductive technology. Conclusions: Most AYAs in our study reported a number of reproductive concerns and fertility-related distress after treatment, which may affect other areas of psychosocial functioning. Females may be more at-risk for distress than males, particularly in situations of uncertainty and limited knowledge. Future work should explore how to best incorporate fertility-related informational and support services more fully into survivorship care. Implications for survivorship care are discussed.

    INTRODUCTION Adult survivors of childhood lower-extremity sarcoma are largely physically inactive, a behavior which potentially compounds their health burden. Altering this behavior requires understanding those factors that contribute to their physical inactivity. Therefore, this investigation sought to identify factors associated with inactivity in this subpopulation of cancer survivors. METHODS Demographic, personal, treatment and physical activity information from adult survivors of childhood lower-extremity sarcomas was obtained from the Childhood Cancer Survivor Study (CCSS) cohort. Generalized linear models were used to identify variables that best identified those individuals who were physically inactive. RESULTS Only 41% of survivors met Center for Disease Control (CDC) activity guidelines. Survivors were 1.20 (95% CI 1.11–1.30) more likely compared to CCSS sibling cohort and 1.12 (95% CI 1.10–1.15) times more likely than the general population to fail to meet CDC guidelines. Significant predictors of physical inactivity included female sex, hemipelvectomy surgery, and platinum and vinca alkaloid chemotherapy. CONCLUSIONS The primary findings of this study are that survivors of childhood onset lower-extremity sarcoma are 1) highly likely to be physically inactive and 2) less likely than their siblings or the general population to regularly exercise. This study has identified treatment related risk factors associated with inactivity that will help health and wellness practitioners develop successful exercise interventions to help these survivors achieve recommended levels of physical activity for health. IMPLICATIONS FOR CANCER SURVIVORS These results suggest that physical activity interventions for adult survivors of childhood lower-extremity sarcomas should be sex specific and responsive to unique physical late effects experienced by these survivors.

    1994-10-01

    Autobiographical interviews with 26 adult male survivors of childhood sexual abuse were audiotaped, transcribed verbatim and content analyzed to identify common psychological themes. Approximately equal numbers of men were abused by male and female perpetrators, almost half came from disrupted or violent homes and a majority had a history of substance abuse. Fifteen psychological themes were identified: Anger, Betrayal, Fear, Homosexuality Issues, Helplessness, Isolation and Alienation, Legitimacy, Loss, Masculinity Issues, Negative Childhood Peer Relations, Negative Schemas about People, Negative Schemas about the Self, Problems with Sexuality, Self Blame/Guilt and Shame/Humiliation. The themes are discussed and illustrated with examples drawn from the transcripts.

    This study focuses on body image discomfort (BID) of 50 adolescent and young adult (AYA) hematologic cancer survivors (age range 15-23; 52% males). The study results were obtained through data from a self-report questionnaire: the Body Uneasiness Test. Findings differed according to gender: a greater proportion of females were in the Risk category of impaired body image than males (χ(2) = 5.258, p < 0.05). No significant body image differences were found according to the type of diagnosis or to the length of survival. To manage survivors' BIDs and to improve their quality of life, assessing BID in AYA cancer survivors is important for identifying those who might be in need of additional supportive care or a program.

    Gibson, Todd M; Ehrhardt, Matthew J; Ness, Kirsten K

    2016-04-01

    Treatment-related obesity and the metabolic syndrome in adult survivors of childhood acute lymphoblastic leukemia (ALL) are risk factors for cardiovascular disease. Both conditions often begin during therapy. Preventive measures, including dietary counseling and tailored exercise, should be initiated early in the course of survivorship, with referral to specialists to optimize success. However, among adults who develop obesity or the metabolic syndrome and who do not respond to lifestyle therapy, medical intervention may be indicated to manage underlying pathology, such as growth hormone deficiency, or to mitigate risk factors of cardiovascular disease. Because no specific clinical trials have been done in this population to treat metabolic syndrome or its components, clinicians who follow adult survivors of childhood ALL should use the existing American Heart Association/National Heart Lung and Blood Institute Scientific Statement to guide their approach.

    Given the paucity of quantitative empirical research on survivors’ resilience and its predictors in the context of long-term recovery after disasters, we examined how resilience predictors differed by gender among adult survivors five years after the Sichuan earthquake. This was a cross-sectional survey study of adult survivors (N = 495; aged 18–60) living in reconstructed communities five years into the recovery process after the Wenchuan earthquake. The instruments we used included assessments of sociodemographic characteristics and earthquake exposure level, the Connor-Davidson Resilience Scale, and the Social Support Rating Scale. Support-seeking behaviors emerged as a significant predictor of male survivors’ resilience, while subjective support and marital status were found to be predictors of female survivors’ resilience. Annual household income and chronic disease were predictors for both male and female groups. The findings of this study can be used in devising methods to boost survivors’ resilience by promoting their satisfaction with social support and their ability to obtain effective support. Additionally, the results suggest how to assist survivors who may have relatively poor resilience. PMID:25811775

    Objectives The study aims to describe the clinical profile of the adult Fontan survivor and identify the worries, symptoms, and the impact of cardiac surveillance most commonly experienced. Design A descriptive, cross-sectional design was used. Setting The study was performed in outpatient adult and pediatric cardiology clinics in university-affiliated and private practice offices. Patients Fifty-four adolescent and adult patients with single ventricle congenital heart disease who have undergone the Fontan procedure participated in the study. The mean age was 26 ± 9 years with 52% female and 63% Caucasian. Outcome Measures Demographic and clinical data were obtained by a standard intake form and retrospective chart reviews. The Congenital Heart Disease TNO/AZL Adult Quality Of Life questionnaire was completed to assess worries, symptoms, and the impact of cardiac surveillance. Results The majority were single (73%), employed or full-time students (93%), with health insurance (94%), had a single left ventricle (78%), the diagnosis of tricuspid atresia or double inlet left ventricle (59%), lateral tunnel Fontan type (44%), history of arrhythmias (76%), left ventricle ejection fraction percentage >50 (66%), oxygen saturations >90% (70%), frequent headaches (50%), scoliosis (22%), varicose veins, ascites, and liver cirrhosis (46%), normal body mass index (59%), and New York Heart Association class I (48%) and II–III (52%). Primary worries related to current health (83%), job/employment (69%), ability to work, (61%) and living independently (54%). The most bothersome symptoms were shortness of breath with ambulation (69%), dizziness (61%), and palpitations (61%). Conclusions Fontan survivors experience residua and sequelae from multiple surgical procedures and the natural disease course. Our results support the need for ongoing assessment of both physical symptoms and psychosocial concerns, and suggest the need for multiple risk factor intervention strategies that

    2011-05-15

    Every year in Canada and the United States, about 26,000 adolescent and young adults (AYA) between ages 15 and 29 years are diagnosed with cancer. Although the majority of AYA cancer patients will survive their primary cancer, many will develop serious health problems or die prematurely secondary to their curative cancer therapy. Much is known about the long-term health outcomes after adolescent cancer. In contrast, there remain substantial gaps in our understanding of the long-term outcomes after most young adult cancers. To optimize the health and quality of life of AYA cancer survivors and improve upon curative cancer therapy, it is essential to further investigate the long-term outcomes of this population. Before embarking upon this endeavor, it is important for the investigator and the funding agency to be cognizant about some of the unique challenges in research of AYA cancer survivors. To this end, the authors present a brief overview of some of the key research challenges, discuss the strengths and limitations of using available AYA cohorts and databases, and highlight potential future directions.

    This article extends earlier reports of an ongoing qualitative inquiry on childhood sexual abuse survivors' experiences with health professionals. In this paper, we aim to enhance understanding of male survivors' experience. While male and female participants express similar anxieties and fears about their encounters with health professionals, there are gender-based differences related to the perceptions of victimhood and manhood; guilt and shame; homophobia; disclosure of abuse; and the expression of vulnerability. The implications of these differences for sensitive health care practice are analyzed within the context of gender relationships and the differential socialization of men. Malecentric communication is proposed as a method for addressing the specific experiences of male survivors in their encounters with health professionals.

    Many childhood brain tumor survivors experience significant neurocognitive late effects across multiple domains that negatively affect quality of life. A theoretical model of survivorship suggests that family functioning and survivor neurocognitive functioning interact to affect survivor and family outcomes. This paper reviews the types of neurocognitive late effects experienced by survivors of pediatric brain tumors. Quantitative and qualitative data from three case reports of young adult survivors and their mothers are analyzed according to the theoretical model and presented in this paper to illustrate the importance of key factors presented in the model. The influence of age at brain tumor diagnosis, family functioning, and family adaptation to illness on survivor quality of life and family outcomes are highlighted. Future directions for research and clinical care for this vulnerable group of survivors are discussed. PMID:21722062

    Burn rehabilitation is a lengthy process associated with physical and psychosocial problems. As a critical area in burn care, the aim was to systematically synthesise the literature focussing on personal perceptions and experiences of adult burn survivors' rehabilitation and to identify factors that influence their rehabilitation. Studies were identified through an electronic search using the databases: PubMed, CINAHL, EMBASE, Scopus, PsycINFO and Trove of peer reviewed research published between 2002 and 2012 limited to English-language research with search terms developed to reflect burn rehabilitation. From the 378 papers identified, 14 research papers met the inclusion criteria. Across all studies, there were 184 participants conducted in eight different countries. The reported mean age was 41 years with a mean total body surface area (TBSA) burn of 34% and the length of stay ranging from one day to 68 months. Significant factors identified as influential in burn rehabilitation were the impact of support, coping and acceptance, the importance of work, physical changes and limitations. This review suggests there is a necessity for appropriate knowledge and education based programmes for burn survivors with consideration given to the timing and delivery of education to facilitate the rehabilitation journey.

    The long-term negative consequences of adverse childhood experiences are well documented. However, less is known about salutogenesis (well-being) among adult survivors of childhood adversity. The 2010 Behavioral Risk Factor Surveillance System data were analyzed to assess the contribution of four health promoting factors (physical activity, smoking abstinence, educational level, social-emotional support) with positive health-related quality of life (HRQoL), among adults who retrospectively reported childhood abuse or exposure to other childhood toxic stressors (n=12,032) and separately for adults who reported childhood sexual abuse (CSA). Outcomes examined included positive self-rated health (good/very good/excellent); mentally unhealthy days (MUDS) and physically unhealthy days (PUDS) in the past 30 days. After controlling for demographic characteristics and existing health conditions, physical activity (p<.05), smoking abstinence (p<.05), education of high school or greater (p<.05), and social-emotional support (p<.05) were associated with positive HRQoL outcomes among adult survivors of childhood adversity and adult survivors of CSA. Each unit increase of the health promoting factor score (0-4) resulted in adjusted odds ratio of 2.1 (95% CI: 1.3-2.4) for self-rated health and 1.6 (95%CI: 1.1-2.6) for <14 PUDs among male CSA survivors; among female survivors the adjusted odds ratios were 2.4 (95% CI: 1.8-3.2) for self-rated health, 2.3 (95% CI: 1.7-3.1) for <14 MUDs, and 2.2 (95% CI: 1.6-3.0) for <14 PUDs. The study validates that a large proportion of adults survive childhood adversities and underscores the importance of the salutogenic paradigm to identify strategies that may contribute to well-being.

    This investigation determined the cardiopulmonary function and fatigue alterations in male cancer survivors during treatment as well as following treatment utilizing similar exercise assessment protocols and individualized, prescriptive exercise interventions. The study included 45 male cancer survivors that were referred by local oncologists. Following a comprehensive screening and physical examination, cardiovascular endurance, pulmonary function, and fatigue were assessed leading to the development of 12-week individualized exercise prescriptions and exercise interventions. The cancer survivors were divided into during treatment (DTm) and following treatment (FTm) groups. Repeated-measures analysis of variance and analyses of covariance were used to compare pre- versus postintervention and between groups. Cardiopulmonary function was maintained in the DTm, whereas the FTm showed significant reductions in resting heart rate (P < .05) with concurrent increases in predicted VO2max and time on treadmill ( P < .05) postexercise intervention. Fatigue levels did not increase in the DTm group, whereas the FTm group showed significant reductions in behavioral fatigue, affective fatigue, sensory fatigue, cognitive/mood fatigue, and total fatigue (P < .05) after the exercise intervention. The results of the current study suggest that moderate intensity, individualized, prescriptive exercise intervention maintains or improves cardiovascular and pulmonary function with concomitant reductions in fatigue in cancer survivors during and following cancer treatment. Exercise appears to be a safe, efficacious strategy for improving physical fitness in cancer survivors during and following treatment.

    Background: Increased survival after cancer in young age has made long-term follow-up studies of high external validity important. In this national cohort study, we explored the impact of cancer in young age on reproduction and marital status in male survivors. Methods: Hazard ratios (HRs) and relative risks (RRs) of reproductive and marital outcomes were studied for male survivors of cancer in young age (<25 years) and cancer-free male comparisons, born during 1965–1985, by linking compulsory national registries in Norway. Results: Male cancer survivors (n=2687) had reduced paternity (HR: 0.72, 95% confidence interval (CI): 0.68–0.76). This was most apparent in survivors of testicular cancer, brain tumours, lymphoma, leukemia and bone tumours, and when diagnosed with cancer before 15 years of age. Male cancer survivors were more likely to avail of assisted reproduction (RR: 3.32, 95% CI: 2.68–4.11). There was no increased risk of perinatal death, congenital malformations, being small for gestational age, of low birth weight or preterm birth in their first offspring. Male cancer survivors were less likely to marry (HR: 0.93, 95% CI: 0.86–1.00), in particular brain tumour survivors. Conclusions: In this national cohort study, we demonstrated reduced paternity and increased use of assisted reproduction among male cancer survivors, but no adverse outcome for their first offspring at birth.

    Purpose Childhood cancer survivors may be at risk for impaired psychosexual functioning as a direct result of their cancer or its treatments, psychosocial difficulties, and/or diminished quality of life. Patients and Methods Two thousand one hundred seventy-eight female adult survivors of childhood cancer and 408 female siblings from the Childhood Cancer Survivor Study (CCSS) completed a self-report questionnaire about their psychosexual functioning and quality of life. On average, participants were age 29 years (range, 18 to 51 years) at the time of the survey, had been diagnosed with cancer at a median age of 8.5 years (range, 0 to 20) and were most commonly diagnosed with leukemia (33.2%) and Hodgkin lymphoma (15.4%). Results Multivariable analyses suggested that after controlling for sociodemographic differences, survivors reported significantly lower sexual functioning (mean difference [MnD], −0.2; P = .01), lower sexual interest (MnD, −0.2; P < .01), lower sexual desire (MnD, −0.3; P < .01), lower sexual arousal (MnD, −0.3; P < .01), lower sexual satisfaction (MnD, −0.2; P = .01), and lower sexual activity (MnD, −0.1; P = .02) compared with siblings. Risk factors for poorer psychosexual functioning among survivors included older age at assessment, ovarian failure at a younger age, treatment with cranial radiation, and cancer diagnosis during adolescence. Conclusion Decreased sexual functioning among female survivors of childhood cancers seems to be unrelated to emotional factors and is likely to be an underaddressed issue. Several risk factors among survivors have been identified that assist in defining high-risk subgroups who may benefit from targeted screening and interventions. PMID:25113763

    Abstract Objective To analyze and compare the health-related quality of life of adult survivors of acute lymphocytic leukemia and Wilms’ tumor amongst themselves and in relation to healthy participants. Methods Ninety participants aged above 18 years were selected and divided into three groups, each comprising 30 individuals. The Control Group was composed of physically healthy subjects, with no cancer history; and there were two experimental groups: those diagnosed as acute lymphocytic leukemia, and those as Wilms’ Tumor. Quality of life was assessed over the telephone, using the Medical Outcomes Study 36-Item Short Form Health Survey. Results Male survivors presented with better results as compared to female survivors and controls in the Vitality domain, for acute lymphocytic leukemia (p=0.042) and Wilms’ tumor (p=0.013). For acute lymphocytic leukemia survivors, in Social aspects (p=0.031), Mental health (p=0.041), and Emotional aspects (p=0.040), the latter also for survivors of Wilms’ tumor (p=0.040). The best results related to the Functional capacity domain were recorded for the experimental group that had a late diagnosis of acute lymphocytic leukemia. There were significant differences between groups except for the Social and Emotional domains for self-perceived health, with positive responses that characterized their health as good, very good, and excellent. Conclusion Survivors of acute lymphocytic leukemia showed no evidence of relevant impairment of health-related quality of life. The Medical Outcomes Study 36-Item Short Form Health Survey (via telephone) can be a resource to access and evaluate survivors. PMID:26537509

    Purpose Adult survivors of childhood cancer experience difficulties in obtaining and maintaining employment. Employment-related challenges are associated with treatment-related health conditions, and may also be related to vocational factors such as career readiness, skill acquisition, and work experience. Unfortunately, little is known about how treatment, health and vocational related factors interact to impact career development among childhood cancer survivors. Methods 385 adult survivors of childhood cancer (42.1% male, median age 38 (21-62) years), participating in the St. Jude Lifetime Cohort study, completed a work experiences survey that included measures of career readiness and vocational identity. Logistic regression was used to compare characteristics of survivors in the low career readiness category to those in the medium or high career readiness category, and structural equation modeling (SEM) was utilized to evaluate associations between career readiness, vocational identity, treatment intensity and physical/emotional health. Results Low career readiness was prevalent in 17.4% of survivors. Univariate analysis did not identify any significant associations between cancer treatment-related factors and career readiness. Unemployed survivors (Odds ratio (OR) 2.3, 95% Confidence Interval (CI) 1.2-4.5), those who were not college graduates (OR 3.0, 95% CI 1.6-5.6), and those who had no personal income (OR 5.9, 95% CI 1.7-30.9) were at increased risk of low career readiness. SEM indicated that associations between treatment intensity, physical health, age at diagnosis and career readiness were mediated by emotional health and vocational identity. 63%, 35%, and 10% of the variance in career readiness, vocational identity, and emotional health, respectively, were explained by this theoretical model. Conclusions The results of this study indicate that individuals who reported low levels of career readiness were more likely to be unemployed, earn less than $40

  2. Emotional concerns and treatment of male partners of female sexual abuse survivors.

    Many men are discovering that they are involved with women who were sexually abused as children. However, male partners of female sexual abuse survivors have thus far received little attention in the literature. As these men increasingly seek treatment with concerns of their own, social workers must become familiar with their emotional experiences and treatment needs. This article outlines the major concerns expressed by 20 male partners of sexual abuse survivors. These concerns included conflicts about expressing needs, frustration with various aspects of their relationships, guilt and shame at having feelings, questions about how to deal with relatives, and sexual issues. The author recommends a treatment approach that combines attention to both the individual's and the couple's concerns and uses insight and the safety of the therapeutic relationship to promote growth. The importance of further outreach to partners of women who were sexually abused as children and the need for increased attention to other partner populations are highlighted.

    During the past 30 years, changes in the treatment of children and adolescents with cancer have led to substantial improvements in survival. Although treatment-related factors have been shown to impact subsequent health status and quality of life, there is limited information on survivors who are now two or more decades after treatment. The Childhood Cancer Survivor Study (CCSS) was established as a resource for investigating the long-term outcomes of a cohort of 5-year survivors of childhood and adolescent cancer, diagnosed between 1970-1986. The CCSS cohort has more than 14,000 active participants, including survivors of leukemia, brain tumors, Hodgkin disease, non-Hodgkin lymphoma, Wilms tumor, neuroblastoma, soft-tissue sarcoma, and bone tumors. Study participants, extensively characterized by their cancer therapy, have provided self-reported sociodemographic- and health-related information. Although the survivor population has been found to be at significantly increased risk of several adverse outcomes, such as late mortality, second cancers, pulmonary complications, pregnancy loss, low birth weight of offspring, and decreased education, the overall proportion of survivors affected is relatively small. Subgroups at high risk of adverse outcomes, defined by treatment-related, demographic, or medical factors, can be identified. The ongoing evaluation of large and diverse cohorts of cancer survivors will aid in further identifying individuals who should be the target of innovative intervention strategies.

    Purpose To determine the prevalence of insulin resistance and other risk factors for cardiovascular disease (CVD) in young adult survivors of childhood acute lymphoblastic leukemia (ALL). Patients and Methods In this cross-sectional evaluation of 118 survivors of childhood ALL (median age, 23.0 years; range, 18 to 37 years), insulin resistance was estimated using the homeostasis model for assessment of insulin resistance (HOMA-IR). Sex-specific comparisons were made with a cohort of 30- to 37-year-old individuals from the same region participating in the Dallas Heart Study (DHS, N = 782). ALL survivors were stratified by treatment with and without cranial radiotherapy (CRT). Results Female ALL survivors had a significantly higher HOMA-IR (CRT, mean 4.6, 95% CI, 3.6 to 5.7; no CRT, mean 3.3, 95% CI, 2.8 to 3.8) in comparison with DHS women (mean 2.4, 95% CI, 2.2 to 2.7). Eighty percent of women treated with CRT had at least three of six CVD risk factors, and they were significantly more likely to have three or more risk factors compared with DHS women (odds ratio [OR], 5.96; 95% CI, 2.15 to 16.47). Male ALL survivors had a significantly higher HOMA-IR (CRT, mean 4.0, 95% CI, 2.8 to 5.6; no CRT, mean 3.4, 95% CI, 2.9 to 3.9) in comparison with DHS men (mean 2.3, 95% CI, 2.1 to 2.6), but were not more likely to have multiple CVD risk factors. Conclusion ALL survivors had an increased prevalence of insulin resistance in comparison with a cohort of older individuals from the same community. Importantly, women treated with CRT seem to have an increased prevalence of multiple CVD risk factors, warranting close monitoring and risk-reducing strategies. PMID:19564534

    Do cancer and cancer treatment influence patients' subsequent pregnancies and outcomes for the offspring? In this study, we compared birth outcomes in 3,915 female and male survivors and 144,653 controls from the general population with similar parity, by merging data from the Cancer Registry and the Medical Birth Registry of Norway. The cancer survivors were diagnosed at age 16-45 in the period 1967-2004. Subgroups of nulliparous survivors (childless before cancer) and primiparous (one pregnancy before and one after cancer) were analyzed, using logistic regression to compare birth outcomes with controls, focusing perinatal death, congenital anomalies, preterm birth (<37 gestational weeks) and low birth weight (LBW, <2,500 g). We adjusted for maternal age, birth period and educational level. Nulliparous female survivors' offspring had increased risk of preterm birth (OR = 1.30 [95% CI 1.05-1.61]) but similar risks of LBW and perinatal death as their controls. Primiparous female survivors differed from their controls, with higher frequency of preterm birth (OR = 1.89 [95% CI 1.40-2.56]) and LBW at term (OR = 2.02 [95% CI 1.15-3.55]). A borderline significant increase of perinatal death was seen among offspring of primiparous female survivors, with OR = 1.92 (95% CI 0.98-3.76). Offspring of male survivors did not differ from their controls. For all cancer types combined, no increased risk of congenital anomalies was seen among either female or male survivors' offspring. Pregnant female cancer survivors should be offered close follow-up, as there is an increased risk of adverse birth outcomes, in particular among those with higher parities.

    This qualitative study examined 30 burn survivors' perceptions of the value of peer support in their own psychosocial rehabilitation. Little research is available that investigates the role of peer support in post-burn recovery in terms of perceived benefits and costs. Findings revealed strong positive views regarding the helpfulness of peer support. Burn survivors reported that peer supporters provided a sense of belonging and affiliation and gave hope and confidence. Two-thirds of the sample had served as peer supporters themselves after receiving their injuries, suggesting that mutual aid does involve reaching out to others. At the same time, survivors spoke of possible costs in helping others. Involving peer supporters in the psychological rehabilitation of burn survivors may be an important complement to the medical team.

    To estimate the risk of late morbidity leading to hospitalization among young adult cancer 5-year survivors compared to the general population and to examine the long-term effects of demographic and disease-related factors on late morbidity, a retrospective cohort of 902 five-year survivors of young adult cancer diagnosed between 1981 and 1999 was identified from British Columbia (BC) Cancer Registry. A matched comparison group (N = 9020) was randomly selected from the provincial health insurance plan. All hospitalizations until the end of 2006 were determined from the BC health insurance plan hospitalization records. The Poisson regression model was used to estimate the rate ratios for late morbidity leading to hospitalization except pregnancy after adjusting for sociodemographic and clinical risk factors. Overall, 455 (50.4%) survivors and 3,419 (37.9%) individuals in the comparison group had at least one type of late morbidity leading to hospitalization. The adjusted risk of this morbidity for survivors was 1.4 times higher than for the comparison group (95% CI = 1.22-1.54). The highest risks were found for hospitalization due to blood disease (RR = 4.2; 95% CI = 1.98-8.78) and neoplasm (RR = 4.3; 95% CI = 3.41-5.33). Survivors with three treatment modalities had three-fold higher risk of having any type of late morbidity (RR = 3.22; 95% CI = 2.09-4.94) than the comparators. These findings emphasize that young adult cancer survivors still have high risks of a wide range of late morbidities.

    The survival rate for childhood acute lymphoblastic leukemia (ALL) is greater than 80%. However, many of these survivors develop long-term chronic health conditions, with a relatively common late effect being neurocognitive dysfunction. Although neurocognitive impairments have decreased in frequency and severity as treatment has evolved, there is a subset of survivors in the current treatment era that are especially vulnerable to the neurotoxic effects of ALL and its treatment. Additionally, little is known about long-term brain development as survivors mature into adulthood. A recent study by Zeller et al. compared neurocognitive function and brain volume in 130 adult survivors of childhood ALL to 130 healthy adults matched on age and sex. They identified the caudate as particularly sensitive to the neurotoxic effects of chemotherapy. We discuss the implications and limitations of this study, including how their findings support the concept of individual vulnerability to ALL and its treatment.

    Successful strategies for branding that are inclusive of male-identified survivors were identified in this qualitative study through semi-structured interviews with leaders from six domestic violence agencies across the United States: four represented traditional domestic violence agencies and two represented specialized agencies with expertise in providing services to nontraditional survivors. The strategic implementation of (a) inclusive language, (b) visual diversity, (c) community outreach, and (d) communication channels emerged as successful strategies in branding in an inclusive way for male-identified survivors. The implementation of these successful strategies provides the opportunity for domestic violence agencies to create an inclusive environment for male-identified survivors and would contribute to a paradigm shift in how domestic violence is viewed.

    2015-08-01

    Adult survivors of childhood brain tumors are at risk for cognitive performance deficits that require the core cognitive skill of working memory. Our goal was to examine the neural mechanisms underlying working memory performance in survivors. We studied the working memory of adult survivors of pediatric posterior fossa brain tumors using a letter n-back paradigm with varying cognitive workload (0-, 1-, 2-, and 3-back) and functional magnetic resonance imaging as well as neuropsychological measures. Survivors of childhood brain tumors evidenced lower working memory performance than demographically matched healthy controls. Whole-brain analyses revealed significantly greater blood-oxygen level dependent (BOLD) activation in the left superior / middle frontal gyri and left parietal lobe during working memory (2-back versus 0-back contrast) in survivors. Left frontal BOLD response negatively correlated with 2- and 3-back working memory performance, Auditory Consonant Trigrams (ACT), and Digit Span Backwards. In contrast, parietal lobe BOLD response negatively correlated with 0-back (vigilance task) and ACT. The results revealed that adult survivors of childhood posterior fossa brain tumors recruited additional cognitive control resources in the prefrontal lobe during increased working memory demands. This increased prefrontal activation is associated with lower working memory performance and is consistent with the allocation of latent resources theory.

    Survivors of pediatric brain tumors (BTs) are at-risk for late effects which may affect mobility within and access to the physical environment. This study examined the prevalence of and risk factors for restricted environmental access in survivors of childhood BTs and investigated the associations between reduced environmental access, health-related quality of life (HRQOL), and survivors' social functioning. In-home evaluations were completed for 78 BT survivors and 78 population-based controls matched on age, sex, and zip-code. Chi-square tests and multivariable logistic regression models were used to calculate odds ratios (ORs) and 95 % confidence intervals (CIs) for poor environmental access and reduced HRQOL. The median age of survivors was 22 years at the time of study. Compared to controls, survivors were more likely to report avoiding most dimensions of their physical environment, including a single flight of stairs (p < 0.001), uneven surfaces (p < 0.001), traveling alone (p = 0.01), and traveling to unfamiliar places (p = 0.001). Overall, survivors were 4.8 times more likely to report poor environmental access (95 % CI 2.0-11.5, p < 0.001). In survivors, poor environmental access was associated with reduced physical function (OR = 3.6, 95 % CI 1.0-12.8, p = 0.04), general health (OR = 6.0, 95 % CI 1.8-20.6, p = 0.002), and social functioning (OR = 4.3, 95 % CI 1.1-17.3, p = 0.03). Adult survivors of pediatric BTs were more likely to avoid their physical environment than matched controls. Restricted environmental access was associated with reduced HRQOL and diminished social functioning. Interventions directed at improving physical mobility may have significant impact on survivor quality of life.

    As a result of earlier diagnosis and improved treatment, the number of cancer survivors is steadily increasing, with over 11 million in the US today. These survivors face a multitude of long-term and late effects as a result of their cancer and its treatment. It is increasingly recognized that this group has complex and ongoing needs for medical care education, surveillance, screening, and support. Many organizations have helped to advance survivorship care; key among them are the National Coalition for Cancer Survivorship, the Institute of Medicine, the Lance Armstrong Foundation, and the Office of Cancer Survivorship of the National Cancer Institute. Important reports have defined goals of care; identified interventions to improve outcomes among survivors; and recognized the need for posttreatment surveillance, healthy lifestyle behaviors, and continued research in all of these areas. With these advances, survivorship care is emerging as a distinct component of the continuum of care in oncology.

    Clergy-perpetrated sexual abuse (CPSA) during childhood represents a tragic betrayal of trust that inflicts damage on the survivor, the family, and the parish community. Survivors often report CPSA has a disturbing impact on their self-identity. Despite intense media coverage of clergy abuse globally in the Catholic Church (and other faith communities) over several decades, relatively few empirical studies have been conducted with survivors. Beyond clinical observations and advocacy group reports, very little is known about survivors' perceptions of how the abuse impacted their long-term self-identity. Using data collected during the 2010 Health and Well-Being Survey, this qualitative analysis represents one of the first large-scale studies with a non-clinical sample of adult male survivors of CPSA from childhood (N = 205). The negative effects of the sexual abuse on participants were expressed across six domains of self-identity: (a) total self, (b) psychological self, (c) relational self, (d) gendered self, (e) aspirational self, and (f) spiritual self. These findings highlight the range and depth of self-suffering inflicted by this pernicious form of sexual violence. The findings are useful for developing clinical services for survivors, shaping public and institutional policies to address clergy-perpetrated sexual abuse, and guiding future research with this population.

  18. Transition of Care for Young Adult Survivors of Childhood and Adolescent Cancer: Rationale and Approaches

    2010-01-01

    Purpose Young adult survivors of childhood and adolescent cancer are an ever-growing population of patients, many of whom remain at lifelong risk for potentially serious complications of their cancer therapy. Yet research shows that many of these older survivors have deficient health-related knowledge and are not engaging in recommended health promotion and screening practices that could improve their long-term outcomes. The purpose of this review is to address these disparities by discussing how formal transition of care from pediatric to adult-focused survivorship services may help meet the unique medical, developmental, and psychosocial challenges of these young adults. Design Literature review and discussion. Results This article summarizes current research documenting the medical needs of young adult survivors, their suboptimal compliance with recommended follow-up, and the rationale, essential functions, current models, and innovative approaches for transition of follow-up care. Conclusion Systematic health care transition constitutes the standard of care for young adult survivors of childhood cancer. In developing a transitional care program, it is necessary to consider the scope of services to be provided, available resources, and other local exigencies that help determine the optimal model for use. Additional research is needed to improve health services delivery to this population. Effective advocacy is needed, particularly in the United States, to ensure the availability of uninterrupted health insurance coverage for survivorship services in young adulthood. PMID:20351333

    Engaging in visual creative expression individually and in a therapeutic setting can be a beneficial experience for cancer survivors; however, most research in this field has been conducted with older adults. The current study aimed to address this gap by utilising van Manen's hermeneutic phenomenology to answer the following question: 'What is the lived experience and meaning of visual creative expression for young adult cancer survivors?' Seven young adults, diagnosed with cancer between the ages of 18 and 35, were interviewed about creative expression experiences, which they engaged in individually and/or in a therapeutic setting. Data analysis included a thematic reflection, guided existential reflection, and a process of writing and rewriting. Two superordinate themes were identified: increased self-understanding and a healing experience. Seven subthemes were also identified and included the following: being in the flow, allowing the body to express itself, renegotiating control, changing one's environment, being seen, respect for art as a separate entity and giving back. Findings suggest that visual creative expression can be a meaningful experience for young adult cancer survivors, and that this experience espouses both similarities and differences from experiences of older adult survivors. Recommendations are made for future research, in addition to implications for practitioners.

    2010-04-01

    Childhood cancer survivorship is a national public health priority, with an increasing number of survivors who face late effects from both disease and treatment. As childhood cancer survivors are living into adulthood, care of the late effects associated with their diagnosis and treatment can become complex. Often these patients no longer have follow-up with the treating pediatric hospital and seek medical care from an adult primary care professional. Combining the results of current survivorship research with clinical experience, we describe common late effects that general internists and primary care professionals may encounter during routine visits with adult survivors of childhood cancer. Recommendations and resources are provided for identifying and managing late effects.

    Purpose Increasing numbers of childhood cancer survivors are seen in primary care settings as young adults. It is unknown how their self-reported health problems differ from those of healthy young adults. Self-reported health problems of cancer survivors and healthy controls are compared in this study. Methods 156 cancer survivors visiting a cancer survivorship program and 138 controls in primary care centers (mean age of 20 years) completed the Health Knowledge Inventory (HKI), a checklist of 35 health problems. Results Cancer survivors reported significantly more health problems than healthy controls (5.6 vs 2.6 problems, p < .001). For cancer survivors, more intense treatment and older age related to Organic/Major problems and Constitutional/Other problems. Female gender related to report of Organic/Major and Constitutional/Other problems for the controls. While at least 20% of both healthy controls and survivors endorsed dermatologic, headache, gastrointestinal and weight problems, survivors endorsed growth, thyroid, kidney, immunological, heart, and fertility problems fourfold over controls. Conclusions Cancer survivors endorse significantly more health problems than healthy controls. However, some problems are reported with equal frequency among the groups. Understanding these similarities and differences between survivors and healthy controls will facilitate patient-centered comprehensive care for young adult cancer survivors. PMID:20453176

    Background To date there are few studies that examine the perspectives of older survivors of childhood brain tumors who are living with their families in terms of their sense of self and their role in their families. Objective To describe how adolescent and young adult survivors (AYA) of childhood brain tumors describe their HRQOL, that is their physical, emotional, and social functioning. Methods This qualitative descriptive study included a purposive sample of 41 AYA survivors of a childhood brain tumor who live with their families. Home interviews were conducted using a semi-structured interview guide. Directed content analytic techniques were used to analyze data using HRQOL as a framework. Results This group of brain tumor survivors described their everyday lives in terms of their physical health, neurocognitive functioning, emotional health, social functioning, and self-care abilities. Overall, survivors struggle for normalcy in the face of changed functioning due to their cancer and the (late) effects of their treatment. Conclusions Neurocognitive issues seemed most compelling in the narratives. The importance of families went beyond the resources, structure, and support for functioning. Their families provided the recognition that they were important beings and their existence mattered to someone. Implications for Practice The value and complexity of care coordination was highlighted by the multifaceted needs of the survivors. Advocacy for appropriate and timely educational, vocational, and social support is critical as part of comprehensive cancer survivorship care. PMID:25950583

    In recent years, reports of institutional abuse within the Catholic Church have emerged and research on the consequences on mental health is in its beginnings. In this study, we report findings on current mental health and resilience in a sample of adult survivors of institutional abuse (N = 185). We compared 3 groups of survivors that differed regarding their current mental health to investigate aspects of resilience, coping, and disclosure. The majority of the sample was male (76.2%), the mean age was 56.28 (SD = 9.46) years, and more than 50.0% of the sample was cohabiting/married. Most of the survivors reported severe mental health problems. Known protective factors (education, social support, age) were not associated with mental health in our sample. Our findings corroborate that institutional abuse has long-term effects on mental health. We found that fewer emotional reactions during disclosure, task-oriented coping, and optimism were associated with better mental health. The study was limited by a cross-sectional design, but we conclude that the kind of institutional abuse reported is especially adverse, and thus typical protective factors for mental health do not apply. Future research should focus on intrapersonal factors and institutional dynamics to improve treatment for persons affected by institutional abuse.

    The main objectives of this study were to test a theory-based mediation model in which the relation between childhood sexual abuse (CSA) and dyadic adjustment is mediated through adult sexual avoidance and sexual compulsivity and to examine the gender-invariance of this model. A sample of 686 adults currently involved in a close relationship completed online self-report computerized questionnaires. Prevalence of CSA was 20% in women and 19% in men. In line with our hypotheses, path analyses and structural equation analyses showed that, for both women and men, CSA was associated with more sexual avoidance and sexual compulsivity, which, in turn, predicted lower couple adjustment. Overall, these findings suggest that both avoidant and compulsive sexuality are relevant intervention targets with couples in which one or both partners are CSA survivors.

    Exercise is a key component of burn rehabilitation across all phases of care. Supervised outpatient exercise programs have been shown to improve outcomes following burn injury. However, little is known about the exercise behaviors of burn survivors who do not undertake such programs. This study aimed to investigate self-reported exercise behaviors and barriers to exercise in adult burn survivors. A short questionnaire survey was conducted on adult burn survivors attending the ambulatory burns clinic of a tertiary hospital over a 6-week period. The collected data were subjected to paired t-tests and Pearson's correlation test. A total of 63 adult burn survivors (mean age 36.5 years) completed the questionnaire. Participants reported exercising less frequently and engaged in fewer different types of exercise compared with pre-burn (P < 0.05). Poor physical conditions and low motivation and enthusiasm were the major barriers to exercise. Participation in supervised exercise programs can be limited by a range of factors including the availability of resources and access to facilities. This preliminary study suggests that there is a need to improve compliance with outpatient exercise programs. Burn survivors appear to exercise less frequently after burn injury. Barriers to exercise following burn injury include poor physical condition and reduced motivation. Further investigation into overall physical activity following burn injury and potential physical and psychological limitations is warranted. Burn clinicians should highly encourage injury survivors to participate in supervised exercise programs when available or to do exercises at home to maximize post-burn injury recovery.

    The objective of this study was to examine the prevalence and factors associated with sexual problems and their relationship to health-related quality of life (HRQOL) in male and female non-Hodgkin lymphoma (NHL) survivors. In this cross-sectional study, 738 NHL survivors (425 men and 313 women; mean time since diagnosis, 6.2 years) in South Korea completed the six-item instrument of adult sexual behavior used by the National Health and Social Life Survey in the United States. HRQOL was measured by two subscales of the EORTC QLQ-C30. Sexual problems were reported by a greater proportion of women (range, 31.9 to 64.4%) than men (range, 23.3 to 49.1%). Among four items common to both sexes, three (lacking interest in sex, unable to achieve orgasm, sex not pleasurable) were significantly more prevalent in women. Significant factors associated with multiple sexual problems in men were older age and being unemployed; in women, they were marital status and comorbidity. Lastly, more significant associations between sexual problems and HRQOL were observed in men than in women. Male and female NHL survivors differ in the prevalence of sexual problems and the factors associated with them as well as their associations with HRQOL. These findings can be used to develop sex-specific interventions to improve sexual function in this population.

    Limited research has addressed factors associated with psychological distress following disasters among non-Western populations. The 2004 tsunami affected 1.7 million people across South Asia and Africa, with considerable variations in trauma-related outcomes. Pretraumatic and peritraumatic conditions associated with trauma-related symptoms in 305 Sri Lankan adult survivors (28% male, aged 18-83 years; mean = 39.9 years; standard deviation = 15.3), clinically assessed 1 month posttsunami, were evaluated retrospectively. Outcome measures were total scores on 11 trauma-related symptoms. Multivariate linear regression analyses tested for associations between pretraumatic and peritraumatic conditions and symptom scores, with peritraumatic conditions adjusted for pretraumatic variables. Pretraumatic conditions of female gender, employment, prior health and social issues, and substance use and peritraumatic conditions of loss of family, witnessing the tsunami, or suffering an injury were associated with trauma-related symptoms. The findings facilitate understanding cultural contexts that define risk factors associated with trauma-related symptoms in Sri Lankans, which are critical for developing culturally appropriate interventions.

    2015-01-01

    With marked advances in early detection and aggressive multimodality treatment, many adult cancers are now associated with good prognoses for disease-free survival. A burgeoning literature examining posttreatment quality-of-life issues has highlighted the numerous challenges experienced by patients and families in the aftermath of cancer treatment, further underscoring a need for new family-based psychosocial support interventions for cancer survivors and their families. This paper describes the clinical protocol for one such intervention, a 1-day “workshop” version of a multiple family group (MFG) for head and neck cancer survivors and their families. Data are reported from our experiences in running five 1-day workshops. Families uniformly reported that they were highly satisfied with their MFG participation, leading us to conclude that the abbreviated 1-day MFG model we are advocating is a promising family-focused support intervention for cancer survivors and their families.

    Background Although the association between psychological trauma and early maladaptive schemas (EMS) is well established in the literature, no study to date has examined the relationship of EMS to PTSD and psychopathologies beyond depression and anxiety in a sample of adult survivors of interpersonal trauma. This information may be useful in helping our understanding on how to best treat interpersonal trauma. Objective We set out to investigate the association between EMS and common forms of psychopathology in a sample of women with a history of interpersonal trauma (n=82). We have hypothesised that survivors of interpersonal trauma will present with elevated EMS scores compared to a non-clinical control group (n=78). We have also hypothesised that unique schemas will be associated with unique psychopathological entities and that subgroups of interpersonal trauma survivors would be present in our sample, with subgroups displaying different profiles of schema severity elevations. Method Participants completed measures of trauma, psychopathology, dissociation, self-esteem, and the Young Schema Questionnaire. Results It was found that survivors of interpersonal trauma displayed elevated EMS scores across all 15 schemas compared to controls. Although the pattern of associations between different psychopathological features and schemas appears to be rather complex, schemas in the domains of Disconnection and Impaired Autonomy formed significant associations with all psychopathological features in this study. Conclusions Our findings support the usefulness of cognitive behavioural interventions that target schemas in the domains of Disconnection and Impaired Autonomy in an effort to modify existing core beliefs and decrease subsequent symptomatology in adult survivors of interpersonal trauma. Highlights of the article Interpersonal trauma survivors are distinguished primarily by a generalised elevation of their maladaptive schemas, rather than a unique schema profile

    Childhood, adolescent, and young adult cancer survivors demonstrate increased cardio-metabolic risk factors, which are amenable to lifestyle changes. The use of technology to impact lifestyle change expands previously limited intervention access, yet little is known about its use. We summarized lifestyle interventions for survivors delivered using technology, finding six studies, primarily targeting physical activity. Study samples were small and durations ranged from 5 to 16 weeks and outcomes modest. Participants were older, white, survivors of leukemia or brain tumors, and the majority received Web-based interventions. Study quality was moderate. Few technology-based interventions have been developed, suggesting an area of opportunity for survivors.

    Survivors of pediatric and young adult cancers remain at risk for subsequent diseases, including those related to human papillomavirus (HPV) infection. Prevention of HPV acquisition through vaccination has become possible over the last decade. HPV vaccines have been shown to be safe and effective, yet rates of vaccination among childhood cancer survivors have remained low. Multiple factors, including stronger advocacy for this intervention from providers, could potentially increase vaccination and lead to lower HPV disease burdens for childhood cancer survivors. Health care providers for survivors of pediatric and adolescent cancers should prioritize counseling for HPV vaccination at follow-up visits. Cancer 2015;121:3435-43. © 2015 American Cancer Society.

    Purpose: This study uses qualitative methods to identify barriers to and facilitators of exercise and healthy eating among adolescent and young adult (AYA) cancer survivors (survivors currently aged 18–39 years and diagnosed with cancer anytime in their lives), as reported by survivors and their primary supporters. Methods: Survivors (Mage = 27.6 years, SD = 6.6 years) had completed active cancer therapy. Survivors and supporters (i.e., nominated by survivors as someone who was a main source of support) attended separate focus group sessions (five survivor focus groups, five supporter focus groups) and were asked to complete a self-reported questionnaire assessing demographic and cancer history and engagement in exercise and healthy eating. Results: In total, 25 survivors and 19 supporters participated. The three overarching themes identified were barriers to exercise and healthy eating (e.g., lack of resources, negative thoughts and feelings, negative social and environmental influences), facilitators of exercise and healthy eating (e.g., cognitive motivators, tools for health behavior implementation, social relationships), and intervention implications (e.g., informational needs, desire for social support). Conclusion: AYA cancer survivors and their supporters identified barriers to and facilitators of healthy lifestyle behaviors, which should be considered when designing interventions to improve the long-term health of survivors.

    The British Childhood Cancer Survivor Study (BCCSS) provides the first detailed investigation of employment and occupation to be undertaken in a large population-based cohort. Previous studies have been limited by design issues such as using small numbers of survivors with specific diagnoses, and involved limited assessment of employment status and occupational level. The BCCSS includes 17,981 5-year survivors of childhood cancer. Employment status and occupational level were ascertained by questionnaire from eligible survivors (n = 14,836). Multivariate logistic regression was used to explore factors associated with employment and occupation, and to compare survivors to their demographic peers in the general population. Employment status was available for 10,257 survivors. Gender, current age, cancer type, radiotherapy, age at diagnosis and epilepsy were consistently associated with being: employed; unable to work; in managerial or non-manual occupations. Overall, survivors were less likely to be working than expected (OR (99% CI): 0.89 (0.81-0.98)), and this deficit was greatest for irradiated CNS neoplasm survivors (0.34 (0.28-0.41)). Compared to the general population, survivors were fivefold more likely to be unable to work due to illness/disability; the excess was 15-fold among CNS neoplasm survivors treated with radiotherapy. Overall survivors were less likely to be in managerial occupations than expected (0.85 (0.77-0.94)). However, bone sarcoma survivors were more likely to be in these occupations than expected (1.37 (1.01-1.85)) and also similarly for non-manual occupations (1.90 (1.37-2.62)). Survivors of retinoblastoma (1.55 (1.20-2.01)) and 'other' neoplasm group (1.62 (1.30-2.03)) were also more likely to be in non-manual occupations than expected.

    There is limited information on body composition, energy balance, and fitness among survivors of childhood acute lymphoblastic leukemia (ALL), especially those treated without cranial radiation therapy (CRT). This analysis compares these metrics among 365 ALL survivors with a mean age of 28.6 ± 5.9 years (149 treated with and 216 without CRT) and 365 age-, sex-, and race-matched peers. We also report risk factors for outcomes among survivors treated without CRT. Male survivors not exposed to CRT had abnormal body composition when compared with peers (% body fat, 26.2 ± 8.2 vs 22.7 ± 7.1). Survivors without CRT had similar energy balance but had significantly impaired quadriceps strength (−21.9 ± 6.0 Newton-meters [Nm]/kg, 60°/s) and endurance (−11.4 ± 4.6 Nm/kg, 300°/s), exercise capacity (−2.0 ± 2.1 ml/kg per minute), low-back and hamstring flexibility (−4.7 ± 1.6 cm), and dorsiflexion range of motion (−3.1 ± 0.9°) and higher modified total neuropathy scores (+1.6 ± 1.1) than peers. Cumulative asparaginase dose ≥120 000 IU/m2 was associated with impaired flexibility, vincristine dose ≥39 mg/m2 with peripheral neuropathy, glucocorticoid (prednisone equivalent) dose ≥8000 mg/m2 with hand weakness, and intrathecal methotrexate dose ≥225 mg with dorsiflexion weakness. Physical inactivity was associated with hand weakness and decreased exercise capacity. Smoking was associated with peripheral neuropathy. Elimination of CRT from ALL therapy has improved, but not eliminated, body-composition outcomes. Survivors remain at risk for impaired fitness. PMID:25814529

    Anecdotal reports suggest that child survivors of the Nazi persecution are functioning well as adults. Ratings of their parents by a randomly selected community sample of young adult Ashkenazi Jews on a scale that measured Schizoid, Paranoid, Depressive/Masochistic and Type A/Normal Aggressive symptoms permitted verification of these reports. Among the parents were groups who were children, adolescents, or young adults in 1945, at the end of World War II. Child-survivor parents did not differ from native-born parents on these measures 40 years later, whereas, consistent with the empirical findings of others, survivors who were adolescents or young adults at the end of the war manifested more paranoid and depressive/masochistic symptoms than native-born parents. To explain this possible greater long-term resilience among those who were child survivors, reference is made to later caretakers, endowment, cognitive and social development, and psychodynamics.

    Few studies have examined how young adult cancer survivors use online social media. The objective of this study was to characterize Facebook engagement by young adult cancer survivors in the context of a physical activity (PA) intervention program. Young adult cancer survivors participated in one of two Facebook groups as part of a 12-week randomized trial of a PA intervention (FITNET) compared to a self-help comparison (SC) condition. A moderator actively prompted group discussions in the FITNET Facebook group, while social interaction was unprompted in the SC group. We examined factors related to engagement, differences in engagement by group format and types of Facebook posts, and the relationship between Facebook engagement and PA outcomes. There were no group differences in the number of Facebook comments posted over 12 weeks (FITNET, 153 vs. SC, 188 p = 0.85) or the proportion of participants that reported engaging within Facebook group discussions at least 1-2 days/week. The proportion of participants that made any posts decreased over time in both groups. SC participants were more likely than FITNET participants to agree that group discussions caused them to become physically active (p = 0.040) and that group members were supportive (p = 0.028). Participant-initiated posts elicited significantly more comments and likes than moderator-initiated posts. Responses posted on Facebook were significantly associated with light PA at 12 weeks (β = 11.77, t(85) = 1.996, p = 0.049) across groups. Engagement within Facebook groups was variable and may be associated with PA among young adult cancer survivors. Future research should explore how to promote sustained engagement in online social networks. ClinicalTrials.gov identifier: NCT01349153.

    The goals of this study were to evaluate the effects of emotional support from friends and parents at two time points (adolescence and adulthood) on adult depression in a nationally representative sample of survivors of childhood sexual abuse (CSA), and examine whether the associations were moderated by the identity of the perpetrator (parent/caregiver vs. not). Data were taken from Waves I and IV of the National Longitudinal Study of Adolescent Health (Add Health). The study sample included 1,238 Add Health participants with a history of CSA and an equivalently sized comparison group of individuals with no history of CSA. Parental support was measured using four items from each wave that assessed the warmth of participants' relationships with their parents and their satisfaction with those relationships. Friend support in adolescence was measured using participants' perceptions of how much their friends cared about them and in adulthood using participants' self-reported number of close friends. Depression was measured using a 10-item subscale of the CES-D. Logistic regressions showed that support from friends and parents in adulthood were significantly associated with lower odds of adult depression in CSA survivors who reported non-parent/caregiver abuse. Among survivors of parent/caregiver abuse, emotional support was not significantly associated with adult depression regardless of when or by whom it was provided. In conclusion, emotional support in adulthood from friends and parents is associated with reduced odds of adult depression in CSA survivors, but only in cases where the abuse was perpetrated by someone other than a parent or caregiver.

    Background Studies of cardiac disease among adult survivors of childhood cancer have generally relied upon self-reported or registry-based data. Objective Systematically assess cardiac outcomes among childhood cancer survivors Design Cross-sectional Setting St. Jude Children's Research Hospital Patients 1,853 adult survivors of childhood cancer, ≥18 years old, and ≥10 years from treatment with cardiotoxic therapy for childhood cancer. Measurements History/physical examination, fasting metabolic and lipid panels, echocardiogram, electrocardiogram (ECG), 6-minute walk test (6MWT) all collected at baseline evaluation. Results Half (52.3%) of the survivors were male, median age 8.0 years (range: 0-24) at cancer diagnosis, 31.0 years (18-60) at evaluation. Cardiomyopathy was present in 7.4% (newly identified at the time of evaluation in 4.7%), coronary artery disease (CAD) in 3.8% (newly identified in 2.2%), valvular regurgitation/stenosis in 28.0% (newly identified in 24.8%), and conduction/rhythm abnormalities in 4.6% (newly identified in 1.4%). Nearly all (99.7%) were asymptomatic. The prevalences of cardiac conditions increased with age at evaluation, ranging from 3-24% among those 30-39 years to 10-37% among those ≥40 years. On multivariable analysis, anthracycline exposure ≥250 mg/m2 increased the odds of cardiomyopathy (odds ratio [OR] 2.7, 95% CI 1.1-6.9) compared to anthracycline unexposed survivors. Radiation to the heart increased the odds of cardiomyopathy (OR 1.9 95% CI 1.1-3.7) compared to radiation unexposed survivors. Radiation >1500 cGy with any anthracycline exposure conferred the greatest odds for valve findings. Limitations 61% participation rate of survivors exposed to cardiotoxic therapies, which were limited to anthracyclines and cardiac-directed radiation. A comparison group and longitudinal assessments are not available. Conclusions Cardiovascular screening identified considerable subclinical disease among adult survivors of childhood

    Posttraumatic stress disorder (PTSD) is highly prevalent in adult survivors of childhood sexual and/or physical abuse. However, intervention studies focusing on this group of patients are underrepresented in earlier meta-analyses on the efficacy of PTSD treatments. The current meta-analysis exclusively focused on studies evaluating the efficacy of psychological interventions for PTSD in adult survivors of childhood abuse. Sixteen randomized controlled trials meeting inclusion criteria could be identified that were subdivided into trauma-focused cognitive behavior therapy (CBT), non-trauma-focused CBT, eye movement desensitization and reprocessing, and other treatments (interpersonal, emotion-focused). Results showed that psychological interventions are efficacious for PTSD in adult survivors of childhood abuse, with an aggregated uncontrolled effect size of g=1.24 (pre- vs. post-treatment), and aggregated controlled effect sizes of g=0.72 (post-treatment, comparison to waitlist control conditions) and g=0.50 (post-treatment, comparison with TAU/placebo control conditions), respectively. Effect sizes remained stable at follow-up. As the heterogeneity between studies was large, we examined the influence of two a priori specified moderator variables on treatment efficacy. Results showed that trauma-focused treatments were more efficacious than non-trauma-focused interventions, and that treatments including individual sessions yielded larger effect sizes than pure group treatments. As a whole, the findings are in line with earlier meta-analyses showing that the best effects can be achieved with individual trauma-focused treatments.

    A maximal aerobic capacity below the 20th percentile is associated with an increased risk of all-cause mortality (Blair 1995). Adult Adult burn survivors have a lower aerobic capacity compared with nonburned adults when evaluated 38 ± 23 days postinjury (deLateur 2007). However, it is unknown whether burn survivors with well-healed skin grafts (ie, multiple years postinjury) also have low aerobic capacity. This project tested the hypothesis that aerobic fitness, as measured by maximal aerobic capacity (VO2max), is reduced in well-healed adult burn survivors when compared with normative values from nonburned individuals. Twenty-five burn survivors (36 ± 12 years old; 13 females) with well-healed split-thickness grafts (median, 16 years postinjury; range, 1-51 years) covering at least 17% of their BSA (mean, 40 ± 16%; range, 17-75%) performed a graded cycle ergometry exercise to test volitional fatigue. Expired gases and minute ventilation were measured via a metabolic cart for the determination of VO2max. Each subject's VO2max was compared with sex- and age-matched normative values from population data published by the American College of Sports Medicine, the American Heart Association, and recent epidemiological data (Aspenes 2011). Subjects had a VO2max of 29.4 ± 10.1 ml O2/kg body mass/min (median, 27.5; range, 15.9-53.3). The use of American College of Sports Medicine normative values showed that mean VO2max of the subjects was in the lower 24th percentile (median, 10th percentile). A total of 88% of the subjects had a VO2max below American Heart Association age-adjusted normative values. Similarly, 20 of the 25 subjects had a VO2max in the lower 25% percentile of recent epidemiological data. Relative to nongrafted subjects, 80 to 88% of the evaluated skin-graft subjects had a very low aerobic capacity. On the basis of these findings, adult burn survivors are disproportionally unfit relative to the general U.S. population, and this puts

    Male-male courtship is infrequent among mature adult Drosophila melanogaster. After pairs of mature adult males expressing a temperature-sensitive allele of the ecdysone receptor (EcR) gene were treated at a restrictive temperature, however, they engaged in elevated levels of male-male courtship. EcR-deficient males courted wildtype males and females, but were not courted by wildtype males. These results suggest that the ecdysone steroid hormone system may have a role in courtship initiation by adult male fruit flies.

    Endocrine complications (particularly gonadal, hypothalamic-pituitary and metabolic) of childhood cancer treatments are common in young adults. Gonadal damage may be the result of chemotherapy or radiotherapy. Fertility preservation must be systematically proposed before initiation of gonadotoxic treatment if only the child is eligible. Hypothalamic-pituitary deficiency is common after brain or total-body irradiation, the somatotropic axis is the most sensitive to irradiation. Pituitary deficiency screening must be repeated since this endocrine consequence can occur many years after treatment. Hormone replacement must be prudent particularly in case of treatment with growth hormone or steroids. Metabolic syndrome, diabetes and cardiovascular damage resulting from cancer treatments contribute to the increase of morbidity and mortality in this population and should be screened routinely even if the patient is asymptomatic. The multidisciplinary management of these adults must be organized and the role of the endocrinologist is now well established.

    This content analysis examines written documentation of telephone calls to a regional sexual assault hotline over a 5-year period. All male callers identified as primary victims were selected for analysis (n = 58) and a corresponding sample of female primary victims (n = 58) were randomly selected for comparison to better understand the help-seeking behavior of sexual assault survivors and inform services accordingly. A summative content analysis revealed significant contrasting themes between male and female victims, including females significantly receiving more referrals and males accessing the hotline to tell their experience of being sexually assaulted due to perceived limited support. Implications for training, practice, and future research are discussed.

    Purpose To evaluate the relative contribution of modifiable cardiovascular risk factors on the development of major cardiac events in aging adult survivors of childhood cancer. Patients and Methods Among 10,724 5-year survivors (median age, 33.7 years) and 3,159 siblings in the Childhood Cancer Survivor Study, the prevalence of hypertension, diabetes mellitus, dyslipidemia, and obesity was determined, along with the incidence and severity of major cardiac events such as coronary artery disease, heart failure, valvular disease, and arrhythmia. On longitudinal follow-up, rate ratios (RRs) of subsequent cardiac events associated with cardiovascular risk factors and cardiotoxic therapy were assessed in multivariable Poisson regression models. Results Among survivors, the cumulative incidence of coronary artery disease, heart failure, valvular disease, and arrhythmia by 45 years of age was 5.3%, 4.8%, 1.5%, and 1.3%, respectively. Two or more cardiovascular risk factors were reported by 10.3% of survivors and 7.9% of siblings. The risk for each cardiac event increased with increasing number of cardiovascular risk factors (all Ptrend < .001). Hypertension significantly increased risk for coronary artery disease (RR, 6.1), heart failure (RR, 19.4), valvular disease (RR, 13.6), and arrhythmia (RR, 6.0; all P values < .01). The combined effect of chest-directed radiotherapy plus hypertension resulted in potentiation of risk for each of the major cardiac events beyond that anticipated on the basis of an additive expectation. Hypertension was independently associated with risk of cardiac death (RR, 5.6; 95% CI, 3.2 to 9.7). Conclusion Modifiable cardiovascular risk factors, particularly hypertension, potentiate therapy-associated risk for major cardiac events in this population and should be the focus of future interventional studies.

    Recent studies indicate that survivors of childhood acute lymphoblastic leukemia (ALL) are at increased risk of obesity and cardiovascular disease, conditions that healthy dietary patterns may help ameliorate or prevent. To evaluate the usual dietary intake of adult survivors of childhood ALL, food frequency questionnaire data were collected from 72 participants, and compared with the 2007 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Cancer Prevention recommendations, the Dietary Approaches to Stop Hypertension (DASH) diet, and the 2005 United States Department of Agriculture (USDA) Food Guide. Mean daily energy intake was consistent with estimated requirements; however, mean body mass index was 27.1 kg/m2 (overweight). Dietary index scores averaged fewer than half the possible number of points on all 3 scales, indicating poor adherence to recommended guidelines. No study participant reported complete adherence to any set of guidelines. Although half the participants met minimal daily goals for 5 servings of fruits and vegetables (WCRF/AICR recommendations) and adult survivors of childhood ALL is not concordant with dietary recommendations that may help reduce their risk of obesity, cardiovascular disease, or other treatment-related late effects.

    Objectives. To investigate physical and mental health and experiences of violence among male and female trafficking survivors in a high-income country. Methods. Our data were derived from a cross-sectional survey of 150 men and women in England who were in contact with posttrafficking support services. Interviews took place over 18 months, from June 2013 to December 2014. Results. Participants had been trafficked for sexual exploitation (29%), domestic servitude (29.3%), and labor exploitation (40.4%). Sixty-six percent of women reported forced sex during trafficking, including 95% of those trafficked for sexual exploitation and 54% of those trafficked for domestic servitude. Twenty-one percent of men and 24% of women reported ongoing injuries, and 8% of men and 23% of women reported diagnosed sexually transmitted infections. Finally, 78% of women and 40% of men reported high levels of depression, anxiety, or posttraumatic stress disorder symptoms. Conclusions. Psychological interventions to support the recovery of this highly vulnerable population are urgently needed. PMID:27077341

    Only a few studies have examined cortisol response to trauma-related stressors in relation to posttraumatic stress disorder (PTSD). We followed a sample of high-exposure survivors of the attacks on September 11, 2001 (9/11; 32 men and 29 women) and examined their cortisol response after recalling the escape from the attack, 7 and 18 months post-9/11. PTSD symptoms and saliva cortisol levels were assessed before and after trauma recollection. Hierarchical regression analyses revealed that PTSD symptoms and male sex predicted increased cortisol response following recollections. For men, elevated cortisol was associated with greater severity of reexperiencing symptoms (p < .001) and lower severity of avoidance symptoms (p < .001). For women, recall-induced cortisol was minimal and unrelated to PTSD symptoms (p = .164 and p = .331, respectively). These findings suggest that augmented cortisol response to trauma-related stressors may be evident in men reporting symptoms of PTSD. Thus, as cortisol abnormalities related to PTSD symptoms appear sex-specific, future research on mechanisms of sex differences in response to trauma is warranted.

    Until recently long-term renal toxicity has not been considered a major late complication of bone marrow transplantation (BMT). Late renal dysfunction has been described in a pediatric population status post-BMT which was attributable to the radiation in the preparatory regimen. A thorough review of adults with this type of late renal dysfunction has not previously been described. Fourteen of 103 evaluable adult patients undergoing allogeneic (96) or autologous (7) bone marrow transplantation, predominantly for leukemia and lymphomas, at the Medical College of Wisconsin (Milwaukee, WI) have had a syndrome of renal insufficiency characterized by increased serum creatinine, decreased glomerular filtration rate, anemia, and hypertension. This syndrome developed at a median of 9 months (range, 4.5 to 26 months) posttransplantation in the absence of specific identifiable causes. The cumulative probability of having this renal dysfunction is 20% at 1 year. Renal biopsies performed on seven of these cases showed the endothelium widely separated from the basement membrane, extreme thickening of the glomerular basement membrane, and microthrombi. Previous chemotherapy, antibiotics, and antifungals as well as cyclosporin may add to and possibly potentiate a primary chemoradiation marrow transplant renal injury, but this clinical syndrome is most analogous to clinical and experimental models of radiation nephritis. This late marrow transplant-associated nephritis should be recognized as a potentially limiting factor in the use of some intensive chemoradiation conditioning regimens used for BMT. Some selective attenuation of the radiation to the kidneys may decrease the incidence of this renal dysfunction.

    Limited research exists examining long-term mental and physical health outcomes in adult survivors of pediatric burns. The authors examine the postinjury lifetime prevalence of common mental and physical disorders in a large pediatric burn cohort and compare the results with matched controls. Seven hundred and forty five survivors of childhood burns identified in the Burn Registry (<18 years old and total BSA >1% between April 1, 1988 and March 31, 2010) were matched 1:5 to the general population based on age at time of injury (index date), sex, and geographic residence. Postinjury rate ratio (RR) was used to compare burn cases and control cohorts for common mental and physical illnesses through physician billings, and hospital claims. RR was adjusted for sex, rural residence, and income. Compared with matched controls, postburn cases had significantly higher RR of all mental disorders, which remained significant (P < .05) after adjustment (major depression RR = 1.5 [confidence limit {CL}: 1.2-1.8], anxiety disorder RR = 1.5 [CL: 1.3-1.8), substance abuse RR = 2.3 [CL: 1.7-3.2], suicide attempt RR = 4.3 [CL: 1.6-12.1], or any mental disorder RR = 1.5 [CL: 1.3-1.8]). The relative rate of some physical illnesses was also significantly increased in burn survivors: arthritis RR = 1.2 (CL: 1.1-1.4), fractures RR = 1.4 (CL: 1.2-1.6), total respiratory morbidity RR = 1.1 (CL: 1.02-1.3), and any physical illness RR = 1.2 (CL: 1.1-1.3). Adult survivors of childhood burn injury have significantly increased rates of postburn mental and physical illnesses. Screening and appropriate management of these illnesses is essential when caring for this population.

    [Purpose] This study aimed to identify the impact of physiotherapy using complex manual therapy as a part of an integrated treatment for sequelae in the musculoskeletal system of torture survivors. [Subjects] This study reviewed 30 male torture survivors presenting with chronic low back pain. They were randomly selected and divided into two groups: an experimental group and a control group. [Methods] For the experimental group, complex manual therapy was performed twice a week for 8 weeks to improve the physical sequelae of patients. Improvement was measured using the PDS-K for Post-traumatic Stress Disorder (PTSD), the Visual Analog Scale (VAS) for pain examination, the Korean Oswestry Disability Index (KODI) for back function assessment, and the Balance System SD as a dynamic balance test. The total period of the intervention for both groups was 8 weeks. [Results] For the experimental group, PDS-K, VAS, KODI, and the dynamic balance test all showed significant improvements after the intervention, which they did not for the control group. In the comparison of the groups, PDS-K, VAS, KODI, and the dynamic balance test all showed significant differences. [Conclusion] Complex manual therapy for torture survivors with chronic low back pain contributes to functional recovery by reducing back pain. The treatment can be considered to have positive effects on sequelae in the musculoskeletal system of torture survivors as they age.

    The aims of this study were as follows: (a) to compare levels of career thoughts and vocational identity between young adult childhood central nervous system (CNS) cancer survivors and noncancer peers and (b) to investigate the contribution of vocational identity and affect on career thoughts among cancer survivors. Participants included 45 young adult CNS cancer survivors and a comparison sample of 60 college students. Participants completed Career Thoughts Inventory, My Vocational Situation, and the Positive and Negative Affect Schedule. Multivariate analysis of variance and multiple regression analysis were used to analyze the data in this study. CNS cancer survivors had a higher level of decision-making confusion than the college students. Multiple regression analysis indicated that vocational identity and positive affect significantly predicted the career thoughts of CNS survivors. The differences in decision-making confusion suggest that young adult CNS survivors would benefit from interventions that focus on providing knowledge of how to make decisions, while increasing vocational identity and positive affect for this specific population could also be beneficial.

    Radiotherapy has been reported to cause neuropsychological dysfunction. Here we examined whether exposure to atomic bomb radiation affected the incidence of dementia among 2286 atomic bomb survivors and controls - all members of the Adult Health Study cohort. Study subjects were non-demented and aged >or=60 years at baseline examination and had been exposed in 1945 at >or=13 years of age to a relatively low dose (or=500 mGy group. Alzheimer disease was the predominant type of dementia in each dose category. After adjustment for potential risk factors, radiation exposure did not affect the incidence rate of either all dementia or any of its subtypes. No case of dementia had a history of therapeutic cranial irradiation. Although we found no relationship between radiation exposure and the development of dementia among atomic bomb survivors exposed at >or=13 years old in this longitudinal study, effects on increased risk of early death among atomic bomb survivors will be considered.

    In the present study, our aim was to examine longitudinal posttraumatic stress symptom (PTSS) trajectories in a Norwegian sample of adults who had experienced sexual abuse during childhood, and to identify predictors of PTSS-trajectory belongingness. The sample consisted of 138 adult survivors of childhood sexual abuse (96.4% women, mean age=42.9years, mean age at the first abuse=5.9 years), recruited from support centers for sexual abuse survivors. The majority (78.3%) reported penetrative abuse, and a large proportion of the sample reported that the perpetrator was a biological parent (38.4%) or someone they trusted (76.1%), reflecting a high severity level of the abusive experiences. Latent Profile Analyses revealed the best overall fit for a two PTSS-trajectories model; one trajectory characterized by sub-clinical and decreasing level of PTSS (54.9%), and the other by high and slightly decreasing level of PTSS (45.1%). Increased odds for belonging to the trajectory with clinical level symptoms was found among those who reported higher levels of exposure to other types of childhood maltreatment (OR=3.69, p=0.002), sexual abuse enforced by physical violence (OR=3.04, p=0.003) or threats (OR=2.56, p=0.014), very painful sexual abuse (OR=2.73, p=0.007), or who had experienced intense anxiety, helplessness or fear during the abuse (OR=2.97, p=0.044). Those in the trajectory with clinical level PTSS reported lower levels of perceived social support and more relational difficulties compared to those in the sub-clinical PTSS trajectory. In conclusion, different longitudinal PTSS trajectories can be found among adult survivors of childhood sexual abuse. Significant predictors of PTSS-trajectory belongingness are discussed alongside their potential implications for preventive efforts and clinical interventions.

    Purpose/Objectives: To identify treatment, intrapersonal, and provider factors that influence childhood cancer survivors' adherence to recommended mammography screening.Design: Secondary analysis of data derived from three consecutive surveys within the Childhood Cancer Survivor Study.Sample: Female childhood cancer survivors: N = 335, X age = 30.92, X years after diagnosis = 21.79.Methods: T tests and structural equation modeling.Main Research Variables: Mammogram recency, health concerns, affect, motivation, and survivor-provider interaction.Findings: Forty-three percent of the variance was explained in mammogram recency. Survivors most likely to follow the recommended mammogram schedule were directly influenced by cancer treatment exposure to mantle radiation (p = 0.01), less intrinsic motivation (p = 0.01), positive affect (p = 0.05), recent visits to an oncology clinic (p = 0.01), discussion of subsequent cancer risks with a physician (p = 0.001), perceptions of more severe late effects (p = 0.05), age (40 years or older) (p survivors at risk.Implications for Nursing: (a) Provide written summaries of treatment exposures and recommended schedule of mammography screening at the end of cancer treatment and throughout follow-up; (b) identify and address survivor symptoms and concerns that may negate screening; and (c) enhance motivation for screening by tailoring personal risk information to health concerns, affect, and readiness for follow-up.

    Burn injury survival means coping with more than just the physical changes and disabilities often encountered after burn injury. Overall quality of life is important, and issues such as sexuality and intimacy are significant facets of quality of life. A literature review revealed limited research regarding current burn center practices related to sexuality and intimacy concerns of burn survivors and their partners. A 28-item survey, designed by seasoned burn care professionals and survivors, was distributed to burn care practitioners attending general sessions at several burn conferences in the United States. Seventy-one (86%) of the invited respondents completed the survey, with nursing representing the majority (63%). Mean tenure working in burn care was 10 years. Mean age of respondents was 40.5 years, with 75% being female and 25% male. Nearly half (47%) reported that specific staff was not designated to discuss sexuality and intimacy with survivors in their center. Sixty-two percent reported that special training regarding sexuality and intimacy was not available at their burn center. Only 14% of respondents indicated that they were "very comfortable" initiating conversation regarding these topics. Fifty-five percent said they were only likely to discuss sexuality and intimacy if the patient/partner initiated the discussion; however, 95% agreed that the patient should not have this responsibility. Although results represent findings from only 37 burn centers, the issues of sexuality and intimacy are not being effectively addressed in the participating centers. Designated staff to provide education is lacking, and there is limited comfort on the part of health care providers in initiating such conversations. These factors seem to often prevent burn care professionals from adequately addressing burn survivor's sexuality and intimacy needs and establish the need for further development of training and educational materials specific to sexuality, intimacy, and

    The current study explored the role of early family environment and adult attachment style in explaining long-term outcomes among child abuse survivors. Adult patients (N = 80) in a trauma treatment program were assessed for clinical diagnosis and administered a multiscale questionnaire. Hierarchical regression analyses were significant for dissociative identity disorder (DID), substance abuse, anxiety disorder, posttraumatic stress, somatization, and six personality disorder dimensions. Adult attachment styles were significant predictors of most outcome variables. Of particular note was the strong contribution of attachment avoidance to DID. Five family environment scales (Independence, Organization, Control, Conflict, Expressiveness) also contributed to various psychopathological outcomes. Evidence emerged supporting a mediating role for attachment style in the link between family independence and five personality disorder dimensions.

    Purpose: Adolescents and young adults (AYAs) employ self-disclosure in normative social interactions and in promoting identity development. Disclosure is associated with numerous psychological and physical benefits. Little research has examined how AYA cancer survivors diagnosed during adolescence disclose their cancer history. Methods: Using a qualitative design, this study explored cancer-related disclosures among survivors (N=26) 16–24 years old at study (M=19.6 years), 14–18 years old at diagnosis (M=15.6 years), and currently at least 6 months post-treatment (M=3.2 years). Semi-structured interview guides were developed and used. Disclosure-related topics included survivorship communications and others' responses to AYAs' disclosure of their cancer experiences. Results: Grounded theory and thematic content analysis guided analyses, with an inductive data-driven approach. Three themes and eight subthemes emerged: “it depends” decision-making processes (don't ask/don't tell, shared experience, relationship potential), perceptions of others' responses (perceived apprehension, positive responses), and methods of disclosure (verbal, written, behavioral). No thematic differences were found by gender or age, although females reported greater frequency of disclosures. Conclusion: Disclosure emerged as a nuanced and complex process. “It depends” decision-making processes were most frequently endorsed, consistent with developmental complexities of this age group. This reflects social and psychological changes and highlights unique challenges for AYA survivors. This also reflects the importance of peers and social interactions as variables that influence disclosure. In the context of AYA cancer survivorship, understanding ways in which disclosure may bolster or hinder social support can assist survivors, clinicians, and families navigate survivorship. Implications for future research are discussed. PMID:25276496

    The aim of this study was to explore the nature and dimensions of institutional child abuse (IA) by the Austrian Catholic Church and to investigate the current mental health of adult survivors. Data were collected in two steps. First, documents of 448 adult survivors of IA (M=55.1 years, 75.7% men) who had disclosed their abuse history to a victim protection commission were collected. Different types of abuse, perpetrator characteristics, and family related risk factors were investigated. Second, a sample of 185 adult survivors completed the Posttraumatic Stress Disorder Checklist (PCL-C) and the Brief Symptom Inventory (BSI). Participants reported an enormous diversity of acts of violent physical, sexual, and emotional abuse that had occurred in their childhood. The majority of adult survivors (83.3%) experienced emotional abuse. Rates of sexual (68.8%) and physical abuse (68.3%) were almost equally high. The prevalence of PTSD was 48.6% and 84.9% showed clinically relevant symptoms in at least one 1 of 10 symptom dimensions (9 BSI subscales and PTSD). No specific pre-IA influence was found to influence the development of PTSD in later life (e.g. poverty, domestic violence). However, survivors with PTSD reported a significantly higher total number of family related risk factors (d=0.33). We conclude that childhood IA includes a wide spectrum of violent acts, and has a massive negative impact on the current mental health of adult survivors. We address the long-term effects of these traumatic experiences in addition to trauma re-activation in adulthood as both bear great challenges for professionals working with survivors.

    The study sample was drawn from the Chicago Longitudinal Study (CLS), an ongoing investigation of a panel of low-income minority children (93% Black) growing up in high-poverty neighborhoods in Chicago. The study sample included 733 males who were active by age 26. Adult criminal records were collected through administrative records and supplemented with self-reports. Outcome measures included incarceration, conviction, and felony conviction by age 26. Probit regression was used to analyze the data. Findings indicated that common childhood predictors were AFDC participation by child's age 3, negative home environment, maltreatment experience, trouble making behavior, and number of school moves. Unique predictors were mother unemployed by child's age 3 for incarceration or jail, four or more children in household by child's age 3 for felony conviction, and mother did not complete high school by child's age 3 and social competence for both incarceration or jail and felony conviction. Implications on crime prevention were discussed.

    Adults who underwent complex atrial baffling as children via Mustard or Senning procedures are at heightened risk for atrial arrhythmias. Antiarrhythmic therapies are typically ineffective in this population. Accordingly, our team of pediatric and adult electrophysiologists investigated the effectiveness of early invasive transbaffle-access techniques to perform early radiofrequency ablation at the source of these clinically significant arrhythmias. For this retrospective study, we selected 11 adult survivors of atrial baffling (mean age, 34 ± 9 yr) who underwent clinically indicated electrophysiologic study after no more than one trial of antiarrhythmic therapy. Using transbaffle-access techniques and 3-dimensional mapping of the venous atria, we found 12 inducible arrhythmias in 10 patients: intra-atrial reentrant tachycardia (n=6), atrioventricular nodal reentrant tachycardia (n=3), focal atrial tachycardia (n=2), and repetitive double firing of the atrioventricular node (n=1). Defining success as short- and midterm freedom from arrhythmia, we analyzed outcomes of radiofrequency ablation at 1 and 6 months. At 1 month, ablation was 100% successful. At 6 months, after 11 ablations in 9 patients, 5 patients had no clinical recurrence, 2 had improved arrhythmia control from minimal medical therapy, and 2 were to undergo repeat study for recurrent tachycardia. In the recurrence-free patients, arrhythmias during electrophysiology study matched the types found clinically before the study. To our knowledge, this is the largest one-year cohort of adult survivors of atrial baffling to have undergone study by a combined pediatric–adult electrophysiology team. We conclude that early invasive transbaffle access for ablating diverse atrial tachyarrhythmias was effective in these patients. PMID:28265208

    We examined healthcare providers' perceptions of the goals of survivorship care and survivor programs, systems-level barriers and individual patient-level barriers to engaging patients in survivorship care, and potential resources for increasing engagement. In 2012, we recruited 21 healthcare providers of young adult survivors of childhood cancers from a children's hospital and a cancer center in the Southeastern USA to complete telephone-based semi-structured interviews. The sample was 45.95 years old (SD = 7.57) on average, 52.4 % female, and 81.0 % MDs. The major goals of survivorship programs identified were medical care management (e.g., addressing late and long-term effects, providing survivorship care plans (SCPs), assisting in transition of care) and holistic care including addressing psychosocial issues and promoting healthy lifestyles. Systems-level barriers to engagement in survivorship care included limited resources (e.g., time), role confusion (e.g., within cancer centers, from treatment team to survivorship care, role of primary care providers), communication challenges within the medical system (e.g., limited tracking of patients, lack of understanding of the role of survivorship clinic), communication challenges with patients (e.g., setting expectations regarding transition to survivorship care), and lack of insurance coverage. Perceived patient-level factors included psychological barriers (e.g., fear, avoidance), resistance to survivorship care, and physical barriers (e.g., distance from survivorship clinics). Resources to address these barriers included increased access to information, technology-based resources, and ensuring valuable services. There are several systems-level and patient-level barriers to survivorship care, thus requiring multilevel interventions to promote engagement in care among young adult survivors of childhood cancer.

    Childhood CNS tumor survivors risk health and functional impairments that threaten normal psychological development and self-perception. This study investigated the extent to which health and functional ability predict adult survivors' body image (BI) and self-confidence regarding sports and physical activity. The study cohort covered 708 eligible ≥ 18 year old CNS tumor survivors, and data from 528 (75 %) were analyzed. Disability was estimated using the Health Utilities Index™ Mark2/3, a multidimensional self-report instrument. Physical self-confidence in terms of BI and sports/physical activity-related self-confidence (SPAS) were assessed using the BI and the Sports/Athletics modules of a standardized self-report assessment scale. In adjusted regression models, global health and functional status (GHFS) predicted BI (B = 0.94, 95 % CI 0.69-1.19) and SPAS (B = 0.79, 95 % CI 0.55-1.04). Emotion and pain, and to a lesser degree cognition, speech and vision disability, were associated with poorer BI and SPAS. Gender, sub-diagnosis, and time since diagnosis influenced the relationship between health status and physical self-confidence outcomes. Females had poorer GHFS, BI and SPAS than males. Decreased health and functional ability following childhood CNS cancer intrudes on physical self-confidence, with females being at heightened risk for both disability and negative self-confidence. Identified disability and gender-related risk calls for a follow-up plan that integrates treatment of psychological sequelae in lifetime monitoring of childhood CNS tumor survivors to restore and protect self-image and self-confidence, essential mental health correlates. An expanded plan should recognize the need for such services, optimizing life-long quality of survival for CNS tumor survivors.

    With a 5 year survival rate of approximately 80%, there is an increasing number of childhood cancer survivors in the United States. Childhood cancer survivors are at an increased risk for physical and psychosocial health problems many years after treatment. Long-term follow-up care should include education, development of individualized follow up plans and screening for health problems in accordance with the Children's Oncology Group survivor guidelines. Due to survivor, provider and healthcare system related barriers, adult survivors of childhood cancer (ASCC) infrequently are receiving care in accordance to these guidelines. In this paper we describe the stepwise process and collaboration between a children's hospital and an adult academic medical center that was implemented to develop the Survivorship Transition Clinic and address the needs of ASCC in our region. In the clinic model that we designed ASCC follow-up with a primary care physician in the adult setting who is knowledgeable about late effects of childhood cancer treatment and are provided transition support and education by a transition nurse navigator.

    Second and higher-order malignancies now comprise about 18% of all incident cancers in the USA, superseding first primary cancers of the breast, lung, and prostate. The occurrence of second malignant neoplasms (SMN) is influenced by a myriad of factors, including the late effects of cancer therapy, shared aetiological factors with the primary cancer (such as tobacco use, excessive alcohol intake, and obesity), genetic predisposition, environmental determinants, host effects, and combinations of factors, including gene-environment interactions. The influence of these factors on SMN in survivors of adult-onset cancer is reviewed here. We also discuss how modifiable behavioural and lifestyle factors may contribute to SMN, and how these factors can be managed. Cancer survivorship provides an opportune time for oncologists and other health-care providers to counsel patients with regard to health promotion, not only to reduce SMN risk, but to minimize co-morbidities. In particular, the importance of smoking cessation, weight control, physical activity, and other factors consonant with adoption of a healthy lifestyle should be consistently emphasized to cancer survivors. Clinicians can also play a critical role by endorsing genetic counselling for selected patients and making referrals to dieticians, exercise trainers, and others to assist with lifestyle change interventions.

    Our objective was to address the gap in knowledge about the extent to which perinatal mental health and risk behaviors are associated with childhood and adult experiences of abuse that arises because of barriers to screening and disclosure about past and current abuse. Survey data from an ongoing study of the effects of posttraumatic stress on childbearing were used to describe four groups of nulliparous women: those with no abuse history, adult abuse only, childhood abuse only, and abuse that occurred during both periods. The rates of abuse history disclosure were higher in the research context than in the clinical settings. Mental health morbidity and risk behaviors occurred in a dose-response pattern with cumulative abuse exposure. Rates of current posttraumatic stress disorder ranged from 4.1% among those never abused to 11.4% (adult only), 16.0% (childhood only), and 39.2% (both periods). Women abused during both periods also were more likely to be using tobacco (21.5%) and drugs (16.5%) during pregnancy. We conclude that mental health and behavioral risk sequelae affect a significant portion of both childhood and adult abuse survivors in prenatal care. The integration into the maternity setting of existing evidence-based interventions for the mental health and behavioral sequelae of abuse is needed.

    The physiological age of adult males of seven mealybug species was measured in relation to the elongation of the male pair of the waxy caudal filaments. These filaments begin to emerge after eclosion and reached their maximum length from 29.4-46.6 h. The studied males were divided into three age groups, expressed as percentages of the total waxy caudal filaments length. Attraction to a sex pheromone source was significantly higher in the oldest male group (maximum filaments growth) compared with youngest one. Only the oldest male group copulated successfully; few of the younger males tested displayed 'courtship' behavior towards conspecific virgin females. The calculated duration of the sexually active phase of the adult male life cycle varied among species ranging from 34.4 to 46.6 h. There were marked variations in the strength of attraction to a pheromone source according to time of day. There was a continuous decrease in sexual activity from morning to evening. Our findings reveal clear maturation periods for adult males of the seven studied species. The long immature phase of the adult male mealybug is probably also related to several physiological processes that are needed to complete male maturation. The most noticeable change is the elongation of the waxy caudal filaments. However, mating may be performed at any time ambient conditions are suitable. Whereas male mealybug flight towards a pheromone source is restricted to a few hours, the male may continue mating activity throughout its sexually active period.

    This study examined the play behaviour in one group of coatis (Nasua narica) at La Selva Biological Station in Costa Rica. We incidentally found adult males playing with juvenile coatis, and conducted post-hoc analyses to investigate this interaction. Coati groups consist of adult females and juveniles of both sexes until male juveniles reach two years of age and leave the band to become solitary. Adult males only tolerate juveniles for a brief period during breeding season when the males court females to mate. Outside of the breeding season, adult males are known to prey on juveniles. In this study, when adult males were present with the band, play occurred more than was expected by chance, and adult males engaged in many of these play bouts. Because the mechanisms driving infanticidal behaviour are not well understood, and adult male coatis show a range of behaviours from infanticide to highly affiliative interactions with juveniles, using coatis as a model system may elucidate mechanisms underlying infanticide.

    This systematic review explored how adult survivors of child sexual abuse experienced nonspecific and trauma-focused talking therapies. Following extensive systematic searches of academic databases, 23 qualitative empirical studies were chosen for review. Using a line-by-line thematic synthesis, four analytical themes developed. These themes were: The Therapeutic Process as a Means for Forming Connections, which discusses therapeutic relationships; Developing a Sense of Self Through the Therapeutic Processes, which identifies stages of developmental recovery; Therapeutic Lights and Black Holes in the Shadows of child sexual abuse, which reflects on how a history of child sexual abuse influenced experiences of therapy; and Healing or Harrowing: Connecting With Others and First-time Experiences, which explores what was helpful, hindering, and new throughout the therapeutic journey. Findings related to participants developing new options for interpersonal relationships through the experience of authentic trust and the experiential learning of control and choice. Recommendations are discussed in relation to developing therapeutic practice and future research.

    People cured from a cancer are not only the previous patients out from the dark tunnel of the disease, in particular if we speak of youngsters. In order for a person to be considered completely cured of childhood cancer, his/her physical conditions, as well as the many associated psychological and social issues must be evaluated. Nowadays, the majority of sick children can expect to be cured, and the number of adult survivors is rapidly becoming a new population requiring special care. Most of them appear to lead normal adult lives. They have obtained high school degrees, good jobs, and several have families and children. Nevertheless, a small percentage show some psychological or social problems, such as anxiety, depression, fear of the future or of relapse, fear of a second primary, or sterility. The most vulnerable among them include females, people in poor financial conditions, the unemployed, and those with low education. There are still some open questions. What will their old age be like? Are they really cured? The most important data in the literature are reported herein. Post-traumatic stress disorder is also discussed. We believe that, in the future, survivors will have two possible outcomes which will be related to the risk of disease and treatment. Those who suffered from low and standard risk disease will reach and enjoy a normal life, while those who underwent very aggressive treatment, with or without stem cell transplantation, might have to cope with a more vulnerable life. We mainly stress the need to avoid all types of psychological and social distress. We recommend providing patients and their families with the information they need and strengthening their coping ability starting from the time of diagnosis and carrying on throughout the whole treatment period.

    Background and objectives: Birthweight differences between kwashiorkor and marasmus suggest that intrauterine factors influence the development of these syndromes of malnutrition and may modulate risk of obesity through dietary intake. We tested the hypotheses that the target protein intake in adulthood is associated with birthweight, and that protein leveraging to maintain this target protein intake would influence energy intake (EI) and body weight in adult survivors of malnutrition. Methodology: Sixty-three adult survivors of marasmus and kwashiorkor could freely compose a diet from foods containing 10, 15 and 25 percentage energy from protein (percentage of energy derived from protein (PEP); Phase 1) for 3 days. Participants were then randomized in Phase 2 (5 days) to diets with PEP fixed at 10%, 15% or 25%. Results: Self-selected PEP was similar in both groups. In the groups combined, selected PEP was 14.7, which differed significantly (P < 0.0001) from the null expectation (16.7%) of no selection. Self-selected PEP was inversely related to birthweight, the effect disappearing after adjusting for sex and current body weight. In Phase 2, PEP correlated inversely with EI (P = 0.002) and weight change from Phase 1 to 2 (P = 0.002). Protein intake increased with increasing PEP, but to a lesser extent than energy increased with decreasing PEP. Conclusions and implications: Macronutrient intakes were not independently related to birthweight or diagnosis. In a free-choice situation (Phase 1), subjects selected a dietary PEP significantly lower than random. Lower PEP diets induce increased energy and decreased protein intake, and are associated with weight gain. PMID:26817484

    Fatigue is a significant problem for adolescent and young adult (AYA) Hodgkin lymphoma (HL) survivors. The relationship between exercise and fatigue is complex. This study explored the trajectory of and the relationship between exercise and fatigue over 36 months post-therapy in a cohort of 103 AYA-aged HL survivors treated on Children's Oncology Group (COG) study AHOD0031. Descriptive statistics and generalized estimating equations were used in this secondary data analysis. Exercise and fatigue improved over time but were unrelated; amount of exercise at end of therapy predicted amount of exercise at 12 (p = 0.02) and 36 (p = 0.0008) months post-therapy.

    Late complications affecting Hodgkin lymphoma (HL) survivors are well described in paediatric and adult-based publications. This study determined the late morbidity and mortality risk for 442 teenage and young adult (TYAs) 5-year HL survivors, diagnosed at 15-24 years of age between 1970 and 1999, identified from the British Columbia Cancer Registry. Treatment details were abstracted from charts. Survivors and a matched comparison cohort were linked to provincial administrative health datasets until December 2006 and regression analysis was performed, providing risk ratios regarding mortality, secondary malignancy and morbidity causing hospitalisation. Sixty (13·6%) survivors experienced late mortality with excess deaths from secondary cancer [standardised mortality ratio (SMR) 18·6; 95% confidence interval (CI) 11-29·4] and non-malignant disease (SMR 3·6; 95% CI 2·2-5·5). Excess secondary cancers (standardised incidence ratio 7·8; 95% CI 5·6-10·5) were associated with radiotherapy [Hazard ratio (HR) 2·7; 95% CI 1-7·7] and female gender (HR 1·8; 95% CI 1-3·4). Of 281 survivors treated between 1981 and 1999, 143 (51%) had morbidity resulting in hospitalisation (relative risk 1·45; 95% CI 1·22-1·73). Hospitalisation significantly increased with combined modality therapy, chemotherapy alone and recent treatment era. TYA HL survivors have excess risk of mortality and secondary malignancy continuing 30 years from diagnosis. Radiotherapy is associated with secondary malignancy and current response-adapted protocols attempt to minimise exposure, but late morbidity causing hospitalisation remains significant.

    The objective of cancer treatment is to secure survival. However, as chemotherapeutic agents can affect the central and peripheral nervous systems, patients must undergo a process of central compensation. We explored the effectiveness of this compensation process by measuring postural behaviour in adult survivors of childhood cancer treated with chemotherapy (CTS). We recruited sixteen adults treated with chemotherapy in childhood for malignant solid (non-CNS) tumours and 25 healthy age-matched controls. Subjects performed posturography with eyes open and closed during quiet and perturbed standing. Repeated balance perturbations through calf vibrations were used to study postural adaptation. Subjects were stratified into two groups (treatment before or from 12 years of age) to determine age at treatment effects. Both quiet (p = 0.040) and perturbed standing (p ≤ 0.009) were significantly poorer in CTS compared to controls, particularly with eyes open and among those treated younger. Moreover, CTS had reduced levels of adaptation compared to controls, both with eyes closed and open. Hence, adults treated with chemotherapy for childhood cancer may suffer late effects of poorer postural control manifested as reduced contribution of vision and as reduced adaptation skills. These findings advocate development of chemotherapeutic agents that cause fewer long-term side effects when used for treating children. PMID:27830766

    Background Although chemotherapy and radiation treatment have contributed to increased survivorship, treatment-induced brain injury has been a concern when examining long-term intellectual outcomes of survivors. Specifically, disruption of brain white matter integrity and its relationship to intellectual outcomes in adult survivors of childhood brain tumors needs to be better understood. Methods Fifty-four participants underwent diffusion tensor imaging in addition to structural MRI and an intelligence test (IQ). Voxel-wise group comparisons of fractional anisotropy calculated from DTI data were performed using Tract Based Spatial Statistics (TBSS) on 27 survivors (14 treated with radiation with and without chemotherapy and 13 treated without radiation treatment on average over 13 years since diagnosis) and 27 healthy comparison participants. Whole brain white matter fractional anisotropy (FA) differences were explored between each group. The relationships between IQ and FA in the regions where statistically lower FA values were found in survivors were examined, as well as the role of cumulative neurological factors. Results The group of survivors treated with radiation with and without chemotherapy had lower IQ relative to the group of survivors without radiation treatment and the healthy comparison group. TBSS identified white matter regions with significantly different mean fractional anisotropy between the three different groups. A lower level of white matter integrity was found in the radiation with or without chemotherapy treated group compared to the group without radiation treatment and also the healthy control group. The group without radiation treatment had a lower mean FA relative to healthy controls. The white matter disruption of the radiation with or without chemotherapy treated survivors was positively correlated with IQ and cumulative neurological factors. Conclusions Lower long-term intellectual outcomes of childhood brain tumor survivors are

    Although sexual dysfunction of childhood sexual abuse survivors has received considerable attention, other sexual difficulties experienced by survivors of CSA, such as sexual fantasies to cues of sexual abuse, have received less attention. In this A-B design case study, a young adult female survivor of childhood sexual abuse presented for treatment at a Midwest rape crisis center. After successful treatment of post-traumatic stress disorder, she complained of unwanted sexual fantasies to sexual abuse cues and concomitant guilt and shame. Following baseline data collection, treatment consisted of self-applied aversion therapy to unwanted sexual arousal to sexual abuse cues. Decrease in sexual arousal to these cues was concurrent with the introduction of treatment. A concomitant decrease in guilt and shame occurred while self-ratings of control increased.

    Background Health complications related to childhood cancer may be influenced by risky health behaviors (RHBs), particularly when RHB co-occur. Limited information describes how RHBs cluster among childhood cancer survivors and siblings and the risk factors for co-occurring RHBs. Methods Latent class analysis was used to identify RHB clusters using longitudinal survey data on smoking, alcohol use, and physical activity from adult survivors (N=4184) and siblings (N=1598) in the Childhood Cancer Survivor Study (CCSS). Generalized logistic regression was used to evaluate associations between demographic characteristics, treatment exposures, psychological distress, health conditions, and cluster membership. Results We identified three RHB clusters: a low risk cluster; an insufficiently active cluster; and a high-risk cluster (tobacco and risky alcohol use and insufficient activity). Compared to siblings, survivors were more likely to be in the insufficiently active cluster (ORadj=1.17; 95% CI 1.06–1.27) and less likely to be in the high-risk cluster (ORadj=0.79; 95% CI 0.69–0.88). Risk factors for high-risk cluster membership included psychological distress, (ORadj=2.76; 95% CI 1.98–3.86) low educational attainment, (ORadj=7.49; 95% CI 5.15–10.88) income <$20,000, (ORadj=2.62; 95% CI 1.93–3.57) being divorced/separated or widowed, (ORadj=1.36; 95% CI 1.03–1.79) and limb amputation (ORadj=1.52; 95% CI 1.03–2.24). Risk factors for the insufficiently active cluster included chronic health conditions, psychological distress, low education or income, being obese or overweight, female sex, non-white race/ethnicity, single marital status, cranial radiation, and cisplatin exposure. Conclusions RHB co-occur in childhood cancer survivors and siblings. Economic and educational disadvantage and psychological distress should be considered in screening and interventions to reduce RHB. PMID:27258389

    The study on stem cells is a hot field in biomedical science in recent years, and has furthered from laboratory to clinical application. Stem cells, according to their developmental stage and differential properties, can be divided into embryonic stem cells, induced PS cells and adult stem cells, among which, adult stem cells have already been applied to the clinical treatment of many systemic diseases. Currently, the study of spermatogonial stem cells and adult stem cells is in the front of the basic researches on the treatment of male infertility, but the time has not yet arrived for their clinical application. This paper outlines the application prospect of adult stem cells in male infertility.

    Background Childhood cancer survivors (CCS) are at increased risk for the metabolic syndrome (MetSyn), which may be reduced with lifestyle modifications. The purpose of this investigation was to characterize lifestyle habits and associations with the MetSyn among CCS. Methods CCS ≥10 years from diagnosis, older than 18 years of age, and participating in the St. Jude Lifetime Cohort Study completed medical and laboratory tests and a food frequency questionnaire (FFQ). The Third National Cholesterol Education Program Adult Treatment Panel (NCEP-ATPIII) criteria were used to classify participants with MetSyn. Anthropometric, FFQ and self-reported physical activity data were used to characterize lifestyle habits according to World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations. Those who met ≥4 of 7 recommendations were classified as following guidelines. Sex stratified log-binomial regression models were used to evaluate associations between dietary/lifestyle habits and MetSyn, adjusted for age, age at cancer diagnosis, cranial radiation, education, and household income. Results Among 1598 CCS (49.2% male, median age 32.7 years, range, 18.9–60.0 years), 31.8% met criteria for MetSyn and 27.0 % followed WCRF/AICR guidelines. Females who did not follow WCRF/AICR guidelines were 2.4 (95% CI 1.7–3.3) and males were 2.2 (95% CI 1.6–3.0) times more likely to have MetSyn than those who followed WCRF/AICR guidelines. Conclusion Adherance to a heart healthy lifestyle is associated with lower risk of MetSyn among CCS. There is a need to determine if lifestyle interventions prevent or remediate MetSyn in CCS.

    This study examined victim and assault characteristics and the nature and extent of coercion, violence, and physical injuries among adult male victims of sexual assaults. Client records of three groups presenting to a sexual assault care center were included: males assaulted by a stranger (n = 64), males assaulted by an acquaintance (n = 81), and females assaulted by an acquaintance (n = 106). Study results revealed that male victims of sexual assault tended to be young, single men who reported high rates of vulnerabilities such as homelessness and physical, psychiatric, and cognitive disabilities. Male stranger assailant victims were more likely to experience assaults involving weapons and physical violence. Injuries sustained by victims and services delivered at the sexual assault care center were similar for both male and female clients. The results of this study reveal new information about violence in male sexual assaults and the vulnerability of the male victims.

    Measuring left ventricular (LV) global longitudinal strain (GLS) is recommended in screening of long-term cancer survivors for cardiotoxicity. However, there are limited data on GLS in this setting, in particular in survivors with apparently normal LV function without risk factors of impaired GLS. In the present study, we measured GLS in 191 adult survivors of childhood lymphoma or acute lymphoblastic leukemia, with normal LV ejection fraction and fractional shortening (FS) and without known hypertension, diabetes mellitus, myocardial infarction, or stroke. We compared GLS in the survivors with 180 controls. Mean GLS was -19.0 ± 2.2% in the survivor group and -21.4 ± 2.0% in the controls (p <0.001). Impaired GLS, defined as mean - 1.96 SDs in the control group, occurred in 53 of 191 survivors (28%). We included survivors with impaired LV ejection fraction and/or FS or traditional risk factors (n = 231 in all) in multiple regression analyses to explore associations with previous cancer treatment. Survivors treated with mediastinal radiotherapy had an odds ratio of impaired GLS of 5.2 (95% confidence interval 2.2 to 12) compared with other survivors. Survivors treated with cumulative anthracycline doses >300 mg/m(2) had an odds ratio of 4.8 (95% confidence interval 1.7 to 14) of impaired GLS. In conclusion, this study demonstrates a high proportion of LV dysfunction assessed by GLS in apparently healthy adult survivors of childhood cancer. Impaired GLS was associated with previous exposure to mediastinal radiotherapy and high doses of anthracyclines. The prognostic role of measuring GLS in this specific patient population should be examined in prospective studies.

    Interventions directed at health behavior change are increasingly being developed for cancer survivors. This study validates decisional balance measures for physical activity and fruit and vegetable (F/V) consumption among adult survivorship population. Participants were N = 86 patients who previously completed primary treatment for breast or prostate cancer for at least 5 years and were enrolled in an e-health intervention that aimed to improve physical activity and nutrition behaviors. Decisional balance, stage of change, F/V consumption, and physical activity were assessed at baseline and 3 months. Factor analysis was used to assess the structure of the decisional balance measures. The relationship between decisional balance, stage, and behavioral outcomes was assessed with mixed model analyses. The two factor structures of each measure were supported. Pros and cons differed across stages of change for both behaviors (p's < .0001). Total Metabolic Equivalent of Task units (METs) were related to decisional balance pros (p = .012) and cons (p = .003). F/V consumption was significantly associated with decisional balance pros (p = .0003), but not cons (p = .112). Overall, findings provide validation for these decisional balance measures as indicators of health behaviors and support the value of using these measures in further research to aid in understanding of behavior change in this population.

    2015-11-01

    Hematopoietic stem cell transplantation (HSCT) has become the standard of care for many malignant and nonmalignant hematologic diseases that don't respond to traditional therapy. There are two types: autologous transplantation (auto-HSCT), in which an individual's stem cells are collected, stored, and infused back into that person; and allogeneic transplantation (allo-HSCT), in which healthy donor stem cells are infused into a recipient whose bone marrow has been damaged or destroyed. There have been numerous advancements in this field, leading to marked increases in the number of transplants performed annually. This article--the first of several on cancer survivorship--focuses on the care of adult allo-HSCT survivors because of the greater complexity of their posttransplant course. The author summarizes potential adverse late and long-term treatment-related effects, with special focus on the evaluation and management of several cardiovascular disease risk factors that can occur either independently or concurrently as part of the metabolic syndrome. These risk factors are potentially modifiable with appropriate nursing interventions and lifestyle modifications.

    The purpose of the current study was to describe male breast cancer in Johannesburg, South Africa, and assess whether male breast cancer patients' perception of their own masculinity was affected by having a cancer commonly seen in women. A retrospective file review was carried out at two hospitals, one private and one government, of male breast cancer patients from 2007 to 2012 followed by a telephone survey of patients identified during review. Of approximately 3,000 breast cancer patients seen in the 5 years reviewed, 23 cases of male breast cancer were identified. Most were diagnosed with invasive ductal carcinoma ( n = 19, 83%). Stage at presentation was from stages 0 to 3 (Stage 0 [ n = 2, 9%], Stage 1 [ n = 3, 13%], Stage 2 [ n = 12, 52%], Stage 3 [ n = 6, 26%]) and no patients were metastatic at presentation. The telephonic survey was completed by 18 patients (78%). Nearly all ( n = 17/18) shared their diagnosis with family and close friends. Two thirds of patients delayed presentation and government hospital patients were more likely to present later than private sector hospital patients. Although most male breast cancer patients sampled did not perceive the breast cancer diagnosis as affecting their masculinity, Black men and those treated in government hospitals were less likely to be aware of male breast cancer, and were more likely to have their perception of their own masculinity affected.

    Background Adult childhood cancer survivors are at higher risk for developing late medical effects related to their cancer treatments. Health promoting behaviors may reduce the risk of some late effects and the severity of others. This paper describes the design and recruitment of the Chicago Healthy Living Study (CHLS), an on-going study designed to examine the health behaviors and BMI of minority adult childhood cancer survivors as compared to non-minority survivors and non-cancer controls. Methods Survivors are identified by the hospital cancer registries at five treating institutions in the Chicago area, after which a multilevel recruitment plan is implemented with the goal of enrolling 450 adult survivors of childhood cancer (150 in each racial/ethnic group). Simultaneously, 300 African-American, Hispanic and Non-Hispanic White adult non-cancer controls (100 in each racial/ethnic group) living in the Chicago area are being recruited via listed, targeted digit dial. All participants complete a 2-hour interview of questionnaires related to diet, physical activity, smoking and associated mediators. Height and weight are also measured. Conclusions The Chicago Healthy Living Study will provide important information on the health behaviors of adult minority childhood cancer survivors that can be used to inform the development of interventions to improve modifiable risks.

    A 66-year-old male presented with a right breast mass, enlarging insidiously over a one-year period after trauma to the site. After the findings were attributed to glandular injury and hematoma, the patient eventually underwent mammographic and ultrasonographic evaluation that demonstrated masses in the breast and the axilla. A subsequent ultrasound-guided biopsy of the breast mass yielded a diagnosis of fibromatosis. However, the imaging features were suggestive of malignancy. Surgical resection was performed and revealed dedifferentiated liposarcoma—a neoplasm with components of well- and poorly differentiated liposarcoma as well as nonlipomatous sarcoma. This tumor type is primarily described in the retroperitoneum and limbs and is especially rare in the breast. We report an unusual case of multifocal primary dedifferentiated liposarcoma involving the breast in a man. PMID:27186240

    The case is described of a 36 year-old man who presented with progressive proximal muscle weakness and weight loss. His serum creatine phosphokinase (CPK) levels were markedly elevated. The muscle biopsy showed lipid storage myopathy. The muscle carnitine concentration was extremely low (5.6% of normal levels), establishing the diagnosis of myopathic carnitine deficiency. The disorder was considered as primary because there were no indications of any other identifiable condition which could result in a secondary carnitine deficiency. The patient was treated with oral L-carnitine (2 g per day) and showed rapid improvement. Primary myopathic carnitine deficiency is a curable disorder and therefore it should always be considered as a potential diagnosis in cases of myopathy in young adults.

    The current study presents preliminary correlational data used to develop a model depicting the psychosocial pathways that lead to the health behaviors of survivors of childhood and young-adult cancer. Data collected from a sample of 18- to 30-year-old cancer survivors (n = 125) was used to examine the relations among interpersonal support and nonsupport, personal agency, avoidance, depressive symptoms and self-efficacy as they related to health behaviors. The outcome measures examined included tobacco and alcohol use, diet, exercise, sunscreen use, medication compliance and follow-up/screening practices. Correlational analyses revealed a number of significant associations among variables. Results are used to inform the development of a health behavior model. Implications for health promotion and survivorship programming are discussed, as well as directions for future research. PMID:27417357

    Purpose Few studies examine the relevance of health-related quality of life (HRQOL) instruments for young adult survivors of childhood cancer (YASCC). This study compared psychometric properties of two survivor-specific instruments, the Quality of Life-Cancer Survivor (QOL-CS) and Quality of Life in Adult Cancer Survivor (QLACS). Methods Data from 151 YASCC who enrolled in Cancer/Tumor Registries of two medical centers were used. We examined construct validity by conducting confirmatory factor analysis using indices of chi-square statistic, comparative fit index (CFI), and root mean square error of approximation (RMSEA). We examined convergent/discriminant validity by comparing Pearson’s correlation coefficients of homogeneous (e.g., physical functioning and pain) of both instruments vs. heterogeneous domains (e.g., physical and psychological functioning). We assessed known-groups validity by examining the extent to which HRQOL differed by late effects and comorbid conditions and calculated relative validity (RV) defined as contrasting F-statistics of individual domains to the domain with the lowest F-statistic. Superior known-groups validity is observed if a domain of one instrument demonstrates a higher RV than other domains of the instruments. Results YASCC data cannot replicate the constructs both instruments intend to measure, suggesting poor construct validity. Correlations of between-homogeneous and between-heterogeneous domains of both instruments were not discernible, suggesting poor convergent/discriminant validity. Both instruments were equally able to differentiate HRQOL between YASCC with and without late effects and comorbid conditions, suggesting similar known-groups validity. Conclusions Neither instrument is superior. Item response theory is suggested to select high quality items from different instruments to improve HRQOL measure for YASCC. PMID:22105163

    Burn injury deformities and obesity have been associated with social integration difficulty and body image dissatisfaction. However, the combined effects of obesity and burn injury on social integration difficulty and body image dissatisfaction are unknown. Adolescent and young adult burn injury survivors were categorized as normal weight (n = 47) or overweight and obese (n = 21). Burn-related and anthropometric information were obtained from patients' medical records, and validated questionnaires were used to assess the main outcomes and possible confounders. Analysis of covariance and multiple linear regressions were performed to evaluate the objectives of this study. Obese and overweight burn injury survivors did not experience increased body image dissatisfaction (12 ± 4.3 vs 13.1 ± 4.4; P = .57) or social integration difficulty (17.5 ± 6.9 vs 15.5 ± 5.7; P = .16) compared with normal weight burn injury survivors. Weight status was not a significant predictor of social integration difficulty or body image dissatisfaction (P = .19 and P = .24, respectively). However, mobility limitations predicted greater social integration difficulty (P = .005) and body image dissatisfaction (P < .001), whereas higher weight status at burn was a borderline significant predictor of body image dissatisfaction (P = .05). Obese and overweight adolescents and young adults, who sustained major burn injury as children, do not experience greater social integration difficulty and body image dissatisfaction compared with normal weight burn injury survivors. Mobility limitations and higher weight status at burn are likely more important factors affecting the long-term social integration difficulty and body image dissatisfaction of these young people.

    Many trauma survivors seem to be reluctant to seek professional help. The aim of the current review was to synthesize relevant literature, and to systematically classify trauma survivors' perceived barriers and facilitators regarding mental health service utilization. The systematic search identified 19 studies addressing military personnel and 17 studies with trauma survivors of the general population. The data analysis revealed that the most prominent barriers included concerns related to stigma, shame and rejection, low mental health literacy, lack of knowledge and treatment-related doubts, fear of negative social consequences, limited resources, time, and expenses. Perceived facilitators lack attention in research, but can be influential in understanding mental health service use. Another prominent finding was that trauma survivors face specific trauma-related barriers to mental health service use, especially concerns about re-experiencing the traumatic events. Many trauma survivors avoid traumatic reminders and are therefore concerned about dealing with certain memories in treatment. These perceived barriers and facilitators were discussed regarding future research and practical implications in order to facilitate mental health service use among trauma survivors.

    The trajectory of posttraumatic stress disorder (PTSD) and PTSD-related symptoms in relation to aging is not well understood. We previously observed higher levels of dissociation as measured by the Dissociative Experiences Scale (DES) among older Holocaust survivors with, compared to those without, PTSD, though scores on the DES in Holocaust survivors were markedly lower than those that had been reported for younger cohorts. We undertook a longitudinal evaluation of dissociation in Holocaust survivors. Twenty-six Holocaust survivors with current PTSD, 30 Holocaust survivors without current PTSD, and 19 nonexposed were evaluated at the initial evaluation and subsequently 8.11 years later. Repeated measures analysis of variance (ANOVA) on the DES scores from these times demonstrated a significant main effect for time and a significant group by time interaction, reflecting a marked decline in Holocaust survivors, particularly those with PTSD. Controlling for age obliterated the effect of time, but not the group by time interaction. A similar pattern was shown with The Clinician Administered PTSD Scale (CAPS) scores. Different symptoms related to PTSD show different trajectories of change with age, with dissociation appearing to be less prominent with age.

    Adult male circumcision (MC) has been shown to reduce the transmission of HPV, HSV, and HIV significantly during vaginal intercourse. However, the benefits of adult MC for men in military service have been poorly documented. Soldiers in war time have additional challenges in maintaining good penile hygiene, rendering uncircumcised men vulnerable to inflammation and infection; these maladies not only negatively impact these individuals, but also undermine the overall military strength. Adult MC can provide some long-term benefits for these military service men. Many African countries have already taken a special interest in adult MC for their military forces, resulting in increased numbers of these surgeries among this special population of men. In this review, we discuss the history of adult MC in the military along with the current trends and economic significance.

    2013-01-01

    Background Post-Traumatic Stress Disorder (PTSD) is a common psychological reaction after large-scale natural disasters. Given the number of people involved and shortage of resources in any major disaster, brief, pragmatic and easily trainable interventions are needed. The aim of this study is to evaluate the efficacy of Narrative Exposure Therapy (NET) as a short-term treatment for PTSD using Chinese earthquake survivors. Methods A randomized waiting-list control pilot study was conducted between December 2009 and March 2010, at the site of the Sichuan earthquake in Beichuan County, China. Adult participants with newly diagnosed Post Traumatic Stress Disorder (PTSD) were randomly allocated to Narrative Exposure Therapy (NET) or a Waiting-List (WL) condition. The latter received NET treatment after a two-week waiting period. To compare the effectiveness of NET in traumatised earthquake survivors, both groups were assessed on PTSD symptoms, general mental health, anxiety and depression, social support, coping style and posttraumatic change before and after treatment and two months post treatment. Results Adult participants (n=22) were randomly allocated to receive NET (n=11) or WL (n=11). Twenty two participants (11 in NET group, 11 in WL) were included in the analysis of primary outcomes. Compared with WL, NET showed significant reductions in PTSD symptoms, anxiety and depression, general mental stress and increased posttraumatic growth. The WL group later showed similar improvements after treatment. These changes remained stable for a two-month follow-up. Measures of social support and coping showed no stable effects. Conclusions NET is effective in treating post-earthquake traumatic symptoms in adult Chinese earthquake survivors. The findings help advance current knowledge in the management of PTSD after natural disasters and inform future research. Larger sample sizes are needed to extend the present findings.

    Spontaneous dissection of the coronary arteries is a rare disease with a wide range of clinical presentations ranging from angina to myocardial infarction (MI); its pathophysiology has not yet been fully established. In this paper, we present the case of a 31-year-old male with an acute coronary syndrome. The initial results of the electrocardiogram and cardiac enzymes were consistent with MI. However, a coronary angio-tomography revealed a dissection of the left main coronary artery and the patient underwent emergent surgery with coronary artery bypass grafting. The treatment of spontaneous dissection of the coronary arteries depends on the anatomical location and the patient's clinical presentation. Coronary revascularization is associated with good results. PMID:24964467

    Purpose Cardiac dysfunction is a serious adverse effect of certain cancer-directed therapies that can interfere with the efficacy of treatment, decrease quality of life, or impact the actual survival of the patient with cancer. The purpose of this effort was to develop recommendations for prevention and monitoring of cardiac dysfunction in survivors of adult-onset cancers. Methods Recommendations were developed by an expert panel with multidisciplinary representation using a systematic review (1996 to 2016) of meta-analyses, randomized clinical trials, observational studies, and clinical experience. Study quality was assessed using established methods, per study design. The guideline recommendations were crafted in part using the Guidelines Into Decision Support methodology. Results A total of 104 studies met eligibility criteria and compose the evidentiary basis for the recommendations. The strength of the recommendations in these guidelines is based on the quality, amount, and consistency of the evidence and the balance between benefits and harms. Recommendations It is important for health care providers to initiate the discussion regarding the potential for cardiac dysfunction in individuals in whom the risk is sufficiently high before beginning therapy. Certain higher risk populations of survivors of cancer may benefit from prevention and screening strategies implemented during cancer-directed therapies. Clinical suspicion for cardiac disease should be high and threshold for cardiac evaluation should be low in any survivor who has received potentially cardiotoxic therapy. For certain higher risk survivors of cancer, routine surveillance with cardiac imaging may be warranted after completion of cancer-directed therapy, so that appropriate interventions can be initiated to halt or even reverse the progression of cardiac dysfunction.

    Robust sex differences in some spatial abilities that favor males have raised the question of whether testosterone contributes to those differences. There is some evidence for prenatal organizational effects of testosterone on male-favoring spatial abilities, but not much is known about the role of pubertal testosterone levels on adult cognitive abilities. We studied the association between pubertal testosterone (at age 14) and cognitive performance in young adulthood (at age 21-23), assessing male-favoring, female-favoring, and sex-neutral cognitive domains in a population-based sample of 130 male and 178 female twins. Pubertal testosterone was negatively associated with performance in the Mental Rotation Test in young adult men (r=-.27), while among women no significant associations between testosterone and cognitive measures were detected. The significant association among men remained after controlling for pubertal development. Confirmatory within-family comparisons with one-sided significance testing yielded a negative correlation between twin pair differences in testosterone levels and Mental Rotation Test performances in 35 male twin pairs (r=-.32): the twin brother with higher testosterone performed less well on the Mental Rotation Test. That association was evident in 18 pairs of dizygotic male twin pairs (r=-.42; analysis controlling for shared environmental effects). In contrast, the association of differences was not evident among 17 monozygotic male twin pairs (r=-.07; analysis controlling for shared genetic influences). Results suggest that pubertal testosterone levels are related specifically to male-favoring spatial ability and only among men. Within-family analyses implicated possible shared genetic effects between pubertal testosterone and mental rotation ability.

    Importance This study provides the first objective data documenting neurocognitive impairment in long-term survivors of childhood osteosarcoma. Objective To examine neurocognitive, neurobehavioral, emotional and quality of life outcomes in long-term survivors of childhood osteosarcoma treated with intravenous high-dose methotrexate. Design Cross-sectional cohort study, with prospective treatment and chronic health predictors. Outcome data was collected from June 2008 to August 2014. Setting Academic research hospital. Participants Survivors of osteosarcoma (n=80; mean [SD] age = 38.9 [7.6] years; time since diagnosis = 24.7 [6.6] years; 42% female) recruited from the St. Jude Lifetime Cohort Study and compared to community controls (n=39; age = 39.03 [11.71] years; 56.4% female). Main Outcome Measures Objective tests of neurocognitive function. Subjective report of neurobehavioral symptoms, emotional distress and quality of life. Within survivors, outcomes were examined in relation to pharmacokinetic indices of methotrexate exposure and current chronic health conditions, which were assessed through medical examination and coded according to Common Terminology Criteria for Adverse Events v4.03. Results Compared to community controls, survivors demonstrated lower reading (p=0.012), attention (p=0.002), memory (p=0.019), processing speed (p<0.001) and executive function (p=0.006). Survivors also fell below national norms on these outcomes. Results of pharmacokinetic analysis showed high-dose methotrexate maximum plasma concentration, median clearance, and median/cumulative exposure were not associated with neurocognitive outcomes. Any grade 3 or 4 Common Terminology Criteria for Adverse Events cardiac, pulmonary or endocrine condition was associated with poorer memory (p=0.006) and slower processing speed (p=0.002). Survivor-reported poor general health was associated with decreased sustained attention (p=0.05) and processing speed (p=0.006). Conclusions Long

    Objectives Domestic violence (DV) is hazardous to survivors' health, from injuries sustained and from resultant chronic physical and mental health problems. Support from friends and relatives is significant in the lives of DV survivors; research shows associations between positive support and the health, well-being and safety of survivors. Little is known about how people close to survivors are impacted. The aim of this study was exploratory, with the following research question: what are the health and well-being impacts on adults who provide informal support to female DV survivors? Design A qualitative study using semistructured interviews conducted face to face, by telephone or using Skype. A thematic analysis of the narratives was carried out. Setting Community-based, across the UK. Participants People were eligible to take part if they had had a close relationship (either as friend, colleague or family member) with a woman who had experienced DV, and were aged 16 or over during the time they knew the survivor. Participants were recruited via posters in community venues, social media and radio advertisement. 23 participants were recruited and interviewed; the majority were women, most were white and ages ranged from mid-20s to 80. Results Generated themes included: negative impacts on psychological and emotional well-being of informal supporters, and related physical health impacts. Some psychological impacts were over a limited period; others were chronic and had the potential to be severe and enduring. The impacts described suggested that those providing informal support to survivors may be experiencing secondary traumatic stress as they journey alongside the survivor. Conclusions Friends and relatives of DV survivors experience substantial impact on their own health and well-being. There are no direct services to support this group. These findings have practical and policy implications, so that the needs of informal supporters are legitimised and met. PMID

    The overall purpose of this study was to determine whether visits to the doctor in the last 12 months, education level, and annual household income for adult males increased the awareness of prostate-specific antigen (PSA) tests. The effect of these factors for the knowledge of PSA exams was performed using statistical analysis. A retrospective secondary database was utilized for this study using the questionnaire in the California Health Interview Survey from 2009. Based on this survey, annual visits to the doctor, higher educational levels attained, and greater take-home pay were statistically significant and the results of the study were equivalent to those hypothesized. This also reflects the consideration of marketing PSA blood test screenings to those adult males who are poor, uneducated, and do not see the doctor on a consistent basis.

  16. An international review of the patterns and determinants of health service utilisation by adult cancer survivors

    PubMed Central

    2012-01-01

    Background There is a need to review factors related to health service utilisation by the increasing number of cancer survivors in order to inform care planning and the organisation and delivery of services. Methods Studies were identified via systematic searches of Medline, PsycINFO, CINAHL, Social Science Citation Index and the SEER-MEDICARE library. Methodological quality was assessed using STROBE; and the Andersen Behavioural Model was used as a framework to structure, organise and analyse the results of the review. Results Younger, white cancer survivors were most likely to receive follow-up screening, preventive care, visit their physician, utilise professional mental health services and least likely to be hospitalised. Utilisation rates of other health professionals such as physiotherapists were low. Only studies of health service use conducted in the USA investigated the role of type of health insurance and ethnicity. There appeared to be disparate service use among US samples in terms of ethnicity and socio-demographic status, regardless of type of health insurance provision s- this may be explained by underlying differences in health-seeking behaviours. Overall, use of follow-up care appeared to be lower than expected and barriers existed for particular groups of cancer survivors. Conclusions Studies focussed on the use of a specific type of service rather than adopting a whole-system approach and future health services research should address this shortcoming. Overall, there is a need to improve access to care for all cancer survivors. Studies were predominantly US-based focussing mainly on breast or colorectal cancer. Thus, the generalisability of findings to other health-care systems and cancer sites is unclear. The Andersen Behavioural Model provided an appropriate framework for studying and understanding health service use among cancer survivors. The active involvement of physicians and use of personalised care plans are required in order to ensure

    This manuscript focuses on four potential stumbling blocks in the multicultural feminist couple treatment of African-American, same-gender loving female adult child sexual abuse survivors: (1) gender roles; (2) "coming out" to self, family, and the community; (3) lesbian couple relationships; and (4) the expression of lesbian sexuality. These four potential barriers to therapeutic outcome within the context of multicultural feminist couple treatment needs to be systematically addressed during the provision of culturally-informed clinical services to African-American, same-gender loving female adult child sexual abuse survivors. The nature and impact of feminism on the family, as an institution, served as the framework for this discussion.

    2015-01-01

    Using historical data from 1,763 birth cohorts from 1800 to 1935 in 13 developed countries, we show that what is now seen as normal—a large excess of female life expectancy in adulthood—is a demographic phenomenon that emerged among people born in the late 1800s. We show that excess adult male mortality is clearly rooted in specific age groups, 50–70, and that the sex asymmetry emerged in cohorts born after 1880 when male:female mortality ratios increased by as much as 50% from a baseline of about 1.1. Heart disease is the main condition associated with increased excess male mortality for those born after 1900. We further show that smoking-attributable deaths account for about 30% of excess male mortality at ages 50–70 for cohorts born in 1900–1935. However, after accounting for smoking, substantial excess male mortality at ages 50–70 remained, particularly from cardiovascular disease. The greater male vulnerability to cardiovascular conditions emerged with the reduction in infectious mortality and changes in health-related behaviors. PMID:26150507

    [Purpose] Elbow injury in male adult kendo players was investigated and examined in order to obtain an indicator of prophylaxis of injury. [Subjects and Methods] The subjects were 22 male adult kendo players aged 25 to 60 years old, and presence or absence of pain, range of motion, and muscle strength in the elbow joints were investigated. In addition, among athletes with limited range of motion (ROM) in the elbow joints, three athletes who had received an explanation and had provided informed consent underwent CT, and the images were examined. [Result] As a result, posterior pain and decreased range of extension motion in the right elbow were noted in 86% of the subjects, and the CT images showed free bone fragments and osteophytes in the olecranon. Also, characteristics were noted that extension muscle strength was stronger than flexion muscle strength in elbow muscle strength. [Conclusion] Based on these results, characteristic disorders in male adult kendo players include an impingement disorder in the posterior region of the right elbow. PMID:28356645

    A cross-sectional study was conducted to explore the prevalence and severity of health-related complaints perceived by adult males of Hong Kong by using the Hong Kong Traditional Chinese versions of the Aging males' symptoms (AMS) scale and the 5-dimensional and 3-level European Quality of life (EQ-5D-3L) questionnaire. A total of 825 adult males aged 40 years or above were surveyed, and observed that 80% of the population was living with little-to-mild levels of aging symptoms with mean total scores ranged between 26.02 ± 7.91 and 32.99 ± 7.91 in different age groups. Such symptoms were correlated with age, especially for the somato-vegetative and sexual symptoms. The most severe AMS symptoms were observed in the oldest age group at 70 years or above, with 76%, 34% and 70% living with moderate-to-severe levels of somato-vegetative, psychological and sexual symptoms, respectively. The result was highly correlated with the EQ-5D-3L questionnaire. Secondly, the Hong Kong Aging males' symptoms (AMS) scale was shown to have good reliability with test-retest coefficient at 0.79 (ranged 0.66-0.87) and Cronbach's alpha coefficient at 0.88 (ranged 0.70-0.84). In summary, the population of Hong Kong male adults was commonly living with little-to-mild levels of aging symptoms, whereas their severity was correlated with age.

    Background On 30 September 2009, a 7.6 magnitude earthquake severely hit the coast of Padang city in West Sumatra, Indonesia leaving about 1,117 people dead and injuring another 3,515. Health consequences such as physical injury, co-morbidity, disability and quality of life over time are seldom reported among survivors after earthquakes. Objectives To investigate the associations between injury, disability and quality of life amongst adult survivors in Padang city after the 2009 earthquake. Design/Methods A prospective cohort study was conducted to compare adult injured (184) and adult non-injured (93) subjects over a 6-month period. Data on physical injury, co-morbidities, disability and quality of life were collected through interviews and measured quantitatively in three phases, i.e. at baseline, end of 3 and 6 months. Results Disability scores were consistently and significantly higher among injured subjects compared to non-injured, even when adjusted for co-morbidities (i.e. acute symptoms and chronic diseases). The highest disability score amongst injured subjects was attributed to ‘feeling discomfort/pain’. Quality of life attribute (QLA) scores, were significantly lower amongst injured people as compared to those non-injured even when adjusted for co-morbidities. The lowest QLA item score amongst the injured was ‘pain, depression and anxiety’. Significant and consistent negative correlations were found between disability and QLA scores in both the injured and non-injured groups. Conclusion Physical injury is significantly correlated with both higher disability and lower quality of life, while disability has significant negative correlation with quality of life. The findings suggest that, through disability, injury may contribute to decreased quality of life. It is therefore recommended to promptly and adequately treat injuries after disasters to prevent any potential for disability and hence restore quality of life. PMID:22629236

    Amodiaquine (AQ) is routinely prescribed as an anti-malarial drug. Here, we evaluated AQ-induced toxicity in the male reproductive system. Eighty adult male Sprague-Dawley rats were randomly divided into four groups that received distilled water (control) or daily doses of 5 mg/kg body weight, 10 mg/kg, or 15 mg/kg AQ for 2 weeks. Testes morphology was analyzed using hematoxylin-and-eosin staining, terminal dUTP nicked-end labeling (TUNEL), and immunostaining whereas protein expression was determined by Western blotting. AQ dose-dependently led to abnormal spermatogenesis. Disruption of the blood-testis barrier and increased germ cell apoptosis were observed in all three AQ-treated groups. Interestingly, AQ-induced damage of spermatogenesis recovered over time, based on the survival of promyelocytic leukemia zinc-finger (PLZF)-positive, undifferentiated spermatogonia. Serum levels of luteinizing hormone and testosterone, as well as testicular testosterone levels, were not significantly altered in AQ-treated groups compared with controls. Collectively, our study suggests that AQ exerts substantial acute side effects on the reproductive systems of adult male rats by inducing the apoptosis of differentiating spermatogenic cells and disruption of blood-testis barrier function.

    The adjustment of feeding behavior in response to hunger and satiety contributes to homeostatic regulation in animals. The fruit fly Drosophila melanogaster feeds on yeasts growing on overripe fruit, providing nutrients required for adult survival, reproduction and larval growth. Here, we present data on how the nutritional value of food affects subsequent yeast consumption in Drosophila adult males. After a period of starvation, flies showed intensive yeast consumption. In comparison, flies stopped feeding after having access to a nutritive cornmeal diet. Interestingly, dietary glucose was equally efficient as the complex cornmeal diet. In contrast, flies fed with sucralose, a non-metabolizable sweetener, behaved as if they were starved. The adipokinetic hormone and insulin-like peptides regulate metabolic processes in insects. We did not find any effect of the adipokinetic hormone pathway on this modulation. Instead, the insulin pathway was involved in these changes. Flies lacking the insulin receptor (InR) did not respond to nutrient deprivation by increasing yeast consumption. Together these results show the importance of insulin in the regulation of yeast consumption in response to starvation in adult D. melanogaster males. PMID:25566097

  7. Patient-specific FDG dosimetry for adult males, adult females, and very low birth weight infants

    NASA Astrophysics Data System (ADS)

    Niven, Erin

    Fluorodeoxyglucose is the most commonly used radiopharmaceutical in Positron Emission Tomography, with applications in neurology, cardiology, and oncology. Despite its routine use worldwide, the radiation absorbed dose estimates from FDG have been based primarily on data obtained from two dogs studied in 1977 and 11 adults (most likely males) studied in 1982. In addition, the dose estimates calculated for FDG have been centered on the adult male, with little or no mention of variations in the dose estimates due to sex, age, height, weight, nationality, diet, or pathological condition. Through an extensive investigation into the Medical Internal Radiation Dose schema for calculating absorbed doses, I have developed a simple patient-specific equation; this equation incorporates the parameters necessary for alterations to the mathematical values of the human model to produce an estimate more representative of the individual under consideration. I have used this method to determine the range of absorbed doses to FDG from the collection of a large quantity of biological data obtained in adult males, adult females, and very low birth weight infants. Therefore, a more accurate quantification of the dose to humans from FDG has been completed. My results show that per unit administered activity, the absorbed dose from FDG is higher for infants compared to adults, and the dose for adult women is higher than for adult men. Given an injected activity of approximately 3.7 MBq kg-1, the doses for adult men, adult women, and full-term newborns would be on the order of 5.5, 7.1, and 2.8 mSv, respectively. These absorbed doses are comparable to the doses received from other nuclear medicine procedures.

    This study examined the equivalence or comparability of the measurement properties of seven selected items measuring posttraumatic growth among self-identified Black (n = 270) and White (n = 707) adult survivors of Hurricane Katrina, using data from the Baseline Survey of the Hurricane Katrina Community Advisory Group Study. Internal consistency reliability was equally good for both groups (Cronbach's alphas = .79), as were correlations between individual scale items and their respective overall scale. Confirmatory factor analysis of a congeneric measurement model of seven selected items of posttraumatic growth showed adequate measures of fit for both groups. The results showed only small variation in magnitude of factor loadings and measurement errors between the two samples. Tests of measurement invariance showed mixed results, but overall indicated that factor loading, error variance, and factor variance were similar between the two samples. These seven selected items can be useful for future large-scale surveys of posttraumatic growth.

    2016-01-01

    Background: There are well-known associations of ionizing radiation with female breast cancer, and emerging evidence also for male breast cancer. In the United Kingdom, female breast cancer following occupational radiation exposure is among that set of cancers eligible for state compensation and consideration is currently being given to an extension to include male breast cancer. Objectives: We compare radiation-associated excess relative and absolute risks of male and female breast cancers. Methods: Breast cancer incidence and mortality data in the Japanese atomic-bomb survivors were analyzed using relative and absolute risk models via Poisson regression. Results: We observed significant (p ≤ 0.01) dose-related excess risk for male breast cancer incidence and mortality. For incidence and mortality data, there are elevations by factors of approximately 15 and 5, respectively, of relative risk for male compared with female breast cancer incidence, the former borderline significant (p = 0.050). In contrast, for incidence and mortality data, there are elevations by factors of approximately 20 and 10, respectively, of female absolute risk compared with male, both statistically significant (p < 0.001). There are no indications of differences between the sexes in age/time-since-exposure/age-at-exposure modifications to the relative or absolute excess risk. The probability of causation of male breast cancer following radiation exposure exceeds by at least a factor of 5 that of many other malignancies. Conclusions: There is evidence of much higher radiation-associated relative risk for male than for female breast cancer, although absolute excess risks for males are much less than for females. However, the small number of male cases and deaths suggests a degree of caution in interpretation of this finding. Citation: Little MP, McElvenny DM. 2017.

    2014-01-01

    Objective The purpose of this study was to test a model of the relations of social reactions to sexual assault disclosure, self-blame and problem drinking. This is the first study to investigate whether type of self-blame has different relationships with social reactions and problem drinking in a large, diverse sample of sexually assaulted women. These relationships are important to investigate in order to identify specific targets for treatment and intervention with sexual assault victims and their social networks. Method Community-residing female sexual assault survivors (N = 1863) in a large metropolitan area completed a mail survey about sexual assault, social reactions to disclosure, self-blame attributions, and problem drinking symptoms. Results Structural equation modeling showed that characterological self-blame mediated the effect of negative social reactions on drinking, but behavioral self-blame did not function as a mediator. A second model showed unique relationships of specific positive and negative social reactions to drinking through characterological and behavioral self-blame. Conclusions Characterological self-blame needs to be targeted in treatment and intervention with survivors, as it appears to be a key mechanism through which social reactions may influence recovery. Secondary prevention with informal social networks should educate people about social reactions to avoid negative reactions and promote those that are helpful, so people can better respond to survivors’ sexual assault disclosures and improve recovery.

    The functional relationship between thyroid, adrenal and gonadal hormones was investigated using adult male rats. Hypothyroidism was produced by the administration of 4-methyl-2-thiouracil (thiouracil) in the drinking water for 2 weeks. Plasma concentrations of TSH dramatically increased, whereas plasma concentrations of tri-iodothyronine and thyroxine decreased in thiouraciltreated rats as compared with euthyroid rats. Hypothyroidism increased basal levels of plasma ACTH and pituitary content of ACTH. The pituitary responsiveness to CRH for ACTH release markedly increased, whereas the adrenal responsiveness to ACTH for corticosterone release decreased. These results indicated that hypothyroidism causes adrenal dysfunction in adult male rats. Pituitary contents of LH and prolactin decreased in hypothyroid rats as compared with euthyroid rats. In addition, hypothyroidism lowered pituitary LH responsiveness to LHRH. Testicular responsiveness to human chorionic gonadotrophin for testosterone release, however, was not different between euthyroid and hypothyroid animals. These results indicated that hypothyroidism causes adrenal dysfunction and results in hypersecretion of ACTH from the pituitary gland. Adrenal dysfunction may contribute to the inhibition of LHRH secretion from the hypothalamus, possibly mediated by excess CRH.

    Toxocariasis is an important, neglected zoonosis caused mainly by Toxocara canis. Although our knowledge of helminth molecular biology is improving through completed draft genome projects, there is limited detailed information on the molecular biology of Toxocara species. Here, transcriptomic sequencing of male and female adult T. canis and comparative analyses were conducted. For each sex, two-thirds (66-67%) of quality-filtered reads mapped to the gene set of T. canis, and at least five reads mapped to each of 16,196 (87.1%) of all 18,596 genes, and 321 genes were specifically transcribed in female and 1467 in male T. canis. Genes differentially transcribed between the two sexes were identified, enriched biological processes and pathways linked to these genes established, and molecules associated with reproduction and development predicted. In addition, small RNA pathways involved in reproduction were characterized, but there was no evidence for piwi RNA pathways in adult T. canis. The results of this transcriptomic study should provide a useful basis to support investigations of the reproductive biology of T. canis and related nematodes.(2).

    OBJECTIVES: This study sought to establish, in Colombia, the importance of factors alleged to be causes or correlates of adult criminality according to the published literature from other countries. METHODS: A comparison was made of arrested male offenders from ages 18 to 30 (n = 223) and similar community controls (n = 222) selected from five cities in Colombia as to their family background, exposure to abuse, family stressors, perceived care and history of childhood disruptive behaviour problems. RESULTS: Compared with neighbourhood controls from similar social classes, offenders were significantly more likely to report having had parents with less education, a mother under the age of 18 or over the age of 35 at time of birth, family members involved in crime, experiencing extreme economic deprivation, parental absence, family conflict, severe punishments, physical abuse, and maternal unavailability, rejection and lack of supervision. Prevalence of childhood disruptive behaviour problems was similar among offenders and controls. These findings appear to be independent of economic status, family size or type, birth order, or primary caregiver. Although the independent contribution of most of these factors is small, once all others have been controlled for, their cumulative effect is strong. CONCLUSIONS: The findings obtained in this Latin American setting do not support the generalized view that adult antisocial behaviour is necessarily preceded by a history of childhood behaviour problems. However, they do add evidence for the importance of family factors in the risk for adult criminality.

    Recent advances in cancer treatment have steadily improved the overall survival rate, and enhancing the quality of life of cancer survivors is the challenge faced at present. One of the major topics in studies on cancer survivors is work-related issues, and the government has been focusing on improving the circumstances of the working population and children. In 2015, the Cancer Control Accelerating Plan set adolescent and young adult(AYA)cancer survivors as the top priority for this plan. Work-related issues of AYA cancer survivors are highly individualized and complicated, mainly because of three characteristics: 1 ) Cancer treatments and/or outpatient follow-ups are accompanied by major life-stage transitions, 2 ) Treatments are prone to be nonstandardized in "rare cancers" or "advanced-stage cancers" and 3 ) Achieving economic independence is difficult because of high medical costs. This article provides some tips for medical professionals working in hospitals on how to support AYA cancer survivors along with their main responsibilities. It also provides an overview of online and offline resources available for supporting this population.

    Childhood and young adult cancer survivors should receive optimum care to reduce the consequences of late effects and improve quality of life. We can facilitate achieving this goal by international collaboration in guideline development. In 2010, the International Late Effects of Childhood Cancer Guideline Harmonization Group was initiated. The aim of the harmonization endeavor is to establish a common vision and integrated strategy for the surveillance of late effects in childhood and young adult cancer survivors. With the implementation of our evidence-based methods, we provide a framework for the harmonization of guidelines for the long-term follow-up of childhood and young adult cancer survivors.

  16. Romantic and sexual relationships, body image, and fertility in adolescent and young adult testicular cancer survivors: a review of the literature.

    2010-08-01

    This review presents a summary of existing knowledge regarding the effect of testicular cancer along four broad domains, including romantic and sexual relationships, body image, and fertility. A total of 37 studies were reviewed. Of note, most research consists of older adult testicular cancer survivors, with very little research attention afforded to adolescent and young adult survivorship. Relationship status (i.e., partnered versus unpartnered) appears to play an important role as it relates to adjustment outcomes in testicular cancer survivors. In addition, sexual function (and thereby fertility) and body image are also frequently compromised. Implications regarding a lack of developmentally focused research on adolescent and young adult testicular cancer survivorship are discussed, along with recommendations for new research.

    2013-01-01

    Background The WHO recently launched the proposal for the 11th version of the International Classification of Diseases (ICD-11) that also includes two diagnoses related to traumatic stress. In contrast to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), ICD-11 will probably, in addition to posttraumatic stress disorder (PTSD), also define a new diagnosis termed “complex posttraumatic stress disorder” (CPTSD). Objective We aimed to apply the proposed ICD-11 criteria for PTSD and CPTSD and to compare their prevalence to the ICD-10 (International Classification of Diseases [10th revision]) PTSD prevalence. In addition, we compiled a list of symptoms for CPTSD based on subthreshold PTSD so as to include a wider group of individuals. Methods To evaluate the appropriateness of the WHO ICD-11 proposal compared to the criteria of ICD-10, we applied the newly introduced criteria for PTSD and CPTSD deriving from the Posttraumatic Stress Disorder Checklist – Civilian Version (PCL-C) and the Brief Symptom Inventory (BSI) scales, to a sample of adult survivors (N=229) of childhood institutional abuse. We evaluated the construct validity of CPTSD using confirmatory factor analysis (CFA). Results More individuals fulfilled the criteria for PTSD according to ICD-10 (52.8%) than the ICD-11 proposal (17% for PTSD only; 38.4% if combined with complex PTSD). The new version of PTSD neutralized the gender effects. The prevalence of CPTSD was 21.4%, and women had a significantly higher rate of CPTSD than men (40.4 and 15.8%, respectively). Those survivors who were diagnosed with CPTSD experienced institutional abuse for a longer time. CFA showed a strong model fit. Conclusion CPTSD is a highly relevant classification for individuals with complex trauma history, but surprisingly, effects of gender were apparent. Further research should thus address gender effects. PMID:24312721

    2016-01-01

    Background With advances in technology, the adoption of wearable devices has become a viable adjunct in poststroke rehabilitation. Regaining ambulation is a top priority for an increasing number of stroke survivors. However, despite an increase in research exploring these devices for lower limb rehabilitation, little is known of the effectiveness. Objective This review aims to assess the effectiveness of lower limb wearable technology for improving activity and participation in adult stroke survivors. Methods Randomized controlled trials (RCTs) of lower limb wearable technology for poststroke rehabilitation were included. Primary outcome measures were validated measures of activity and participation as defined by the International Classification of Functioning, Disability and Health. Databases searched were MEDLINE, Web of Science (Core collection), CINAHL, and the Cochrane Library. The Cochrane Risk of Bias Tool was used to assess the methodological quality of the RCTs. Results In the review, we included 11 RCTs with collectively 550 participants at baseline and 474 participants at final follow-up including control groups and participants post stroke. Participants' stroke type and severity varied. Only one study found significant between-group differences for systems functioning and activity. Across the included RCTs, the lowest number of participants was 12 and the highest was 151 with a mean of 49 participants. The lowest number of participants to drop out of an RCT was zero in two of the studies and 19 in one study. Significant between-group differences were found across three of the 11 included trials. Out of the activity and participation measures alone, P values ranged from P=.87 to P ≤.001. Conclusions This review has highlighted a number of reasons for insignificant findings in this area including low sample sizes, appropriateness of the RCT methodology for complex interventions, a lack of appropriate analysis of outcome data, and participant stroke

    Background Little attention has been paid to selecting and developing health-related quality of life (HRQOL) measurement tools for young adult survivors of childhood cancer (YASCC). The primary purpose of this study was to develop a HRQOL tool for YASCC based on three legacy instruments. Methods Data collected from 151 YASCC were analyzed. HRQOL was measured using the Medical Outcomes Study SF-36, Quality of Life in Adult Cancer Survivors, and Quality of Life-Cancer Survivor. We used the following stages to develop our HRQOL tool: mapping items from three instruments into a common HRQOL construct, checking dimensionality using confirmatory factor analyses (CFA), and equating items using Rasch modeling. Results We assigned 123 items to a HRQOL construct comprised of six generic and eight survivor-specific domains. CFA retained 107 items that meet the assumptions of unidimensionality and local independence. Rasch analysis retained 68 items that satisfied the indices of information-weighted/outlier-sensitive fit statistic mean square. However, items in most domains possess relatively easy measurement properties, whereas YASCC’s underlying HRQOL was on the middle to higher levels. Conclusions Psychometric properties of the established tool for measuring HRQOL of YASCC were not satisfied. Future studies need to refine this tool, especially adding more challenging items.

    Objective Survivors of childhood cancer are at an increased risk for reduced quality of life (QOL), yet few studies have explored factors associated with improving health-related QOL (HRQOL) in this population. We thus explored the relationship between physical activity (PA) and HRQOL among survivors of childhood cancer. Methods A total of 215 survivors of childhood lymphoma, leukemia, and central nervous system (CNS) cancers completed mailed surveys that elicited information regarding leisure-time PA (LTPA) measured in metabolic equivalents, HRQOL, and diagnostic and demographic factors. Correlations and adjusted regression models were use to explore the relationship between LTPA and HRQOL. Results In the total sample, modest yet significant linear associations were observed between LTPA and overall HRQOL (β = 0.17, p < 0.01) as well as each of the respective subscales (β = 0.11–0.23 and p < 0.05 to < 0.001). Among adolescent survivors of childhood cancer, LTPA was significantly associated with overall HRQOL (β = 0.27), cancer worry (β = 0.36), cognitive function (β = 0.32), body appearance (β = 0.29), and social function (β = 0.27) (all p < 0.05). Among adult survivors of childhood cancer, LTPA was only significantly associated with physical function (β = 0.28, p < 0.001). Conclusions Significant associations exist between LTPA and HRQOL; however, the association was stronger and observed in more domains for adolescent survivors of childhood cancer. More research is needed to determine the antecedents and consequences of physical activity in this population. PMID:19918964

    In the present study, we examined the role of cumulative childhood maltreatment experiences for several health related outcomes in adulthood, including symptoms of psychological distress as well as perceived social support and hardiness. The sample comprised adult survivors of sexual abuse (N=278, 95.3% women, mean age at first abusive incident=6.4 years). One-way ANOVAs revealed a statistically significant dose-response relation between cumulative childhood maltreatment scores and self-reported symptoms of posttraumatic stress (PTSS), anxiety, depression, eating disorders, dissociation, insomnia, nightmare related distress, physical pain, emotional pain, relational problems, self-harm behaviors as well as on a measure of symptom complexity. Cumulative childhood maltreatment was also associated with lower levels of work functioning. An inverse dose-response relation was found for perceived social support and hardiness. Using a Bonferroni corrected alpha level, cumulative childhood maltreatment remained significantly associated with all outcome measures with the exception of eating disorder symptoms after controlling for abuse-related independent variables in hierarchical regression analyses. Results add to previous literature by showing that dose-response relation between cumulative childhood adversities and adult symptom outcomes could also be identified in a sample characterized by high exposure to adversities, and lends support to the notion put forth by previous authors that cumulative childhood adversities seem to be related to the severity of adult health outcomes in a rule-governed way.

    Background Stroke is a major cause of disability in older adults, but the evidence around post-acute treatment is limited and heterogeneous. We aimed to identify profiles of older adult stroke survivors admitted to intermediate care geriatric rehabilitation units. Methods We performed a cohort study, enrolling stroke survivors aged 65 years or older, admitted to 9 intermediate care units in Catalonia-Spain. To identify potential profiles, we included age, caregiver presence, comorbidity, pre-stroke and post-stroke disability, cognitive impairment and stroke severity in a cluster analysis. We also proposed a practical decision tree for patient’s classification in clinical practice. We analyzed differences between profiles in functional improvement (Barthel index), relative functional gain (Montebello index), length of hospital stay (LOS), rehabilitation efficiency (functional improvement by LOS), and new institutionalization using multivariable regression models (for continuous and dichotomous outcomes). Results Among 384 patients (79.1±7.9 years, 50.8% women), we identified 3 complexity profiles: a) Lower Complexity with Caregiver (LCC), b) Moderate Complexity without Caregiver (MCN), and c) Higher Complexity with Caregiver (HCC). The decision tree showed high agreement with cluster analysis (96.6%). Using either linear (continuous outcomes) or logistic regression, both LCC and MCN, compared to HCC, showed statistically significant higher chances of functional improvement (OR = 4.68, 95%CI = 2.54–8.63 and OR = 3.0, 95%CI = 1.52–5.87, respectively, for Barthel index improvement ≥20), relative functional gain (OR = 4.41, 95%CI = 1.81–10.75 and OR = 3.45, 95%CI = 1.31–9.04, respectively, for top Vs lower tertiles), and rehabilitation efficiency (OR = 7.88, 95%CI = 3.65–17.03 and OR = 3.87, 95%CI = 1.69–8.89, respectively, for top Vs lower tertiles). In relation to LOS, MCN cluster had lower chance of shorter LOS than LCC (OR = 0.41, 95%CI = 0.23–0

    Background Biliary atresia (BA) is a rare cholestatic disease of infancy. Kasai portoenterostomy and liver transplantation (LT) are the two sequential treatment options. An increasing number of patients survive into adulthood. Little is known about their health-related quality of life (HRQOL). This study aims to compare HRQOL of transplanted and nontransplanted patients in a cohort of young adult BA survivors. Patients and Methods RAND-36 and Liver Disease Index Score (LDSI) questionnaires were sent to eligible adult patients with BA. Clinical characteristics were obtained from the NeSBAR (Netherlands Study group on Biliary Atresia Registry) and the national pediatric LT database. RAND-36 domain and summary scores were compared with those of an age-matched Dutch reference group. The correlations between several clinical variables and HRQOL were analyzed. Results Mean RAND-36 domain and summary scores of transplanted (n = 15) and nontransplanted (n = 25) patients with BA (response 74%) were similar to the reference scores, with the exception of a decreased general health perception in nontransplanted patients (63 ± 21 vs. 75 ± 17; [p < 0.001], particularly in females. RAND-36 domain and summary scores were not significantly correlated to age at LT, time since LT, serum bilirubin, aspartate amino transferase or albumin levels, but were moderately to strongly correlated to LDSI total scores (r values 0.35-0.77). Conclusions Overall, young adult patients with BA have a HRQOL similar to an age-matched reference group. However, general health perception of nontransplanted patients, particularly of females, was decreased. HRQOL is correlated to liver disease symptoms but not to liver biochemistry parameters. Nontransplanted females and patients suffering from liver disease-associated symptoms may be a target for tailored supportive interventions.

    Peer support has long been recognised as an essential component of a supportive network for people facing adversity. In particular, burn survivor peer support is a valuable and credible resource available to those rehabilitating from a severe burn. The aim of this study was to explore burn survivors' experiences of providing and receiving inpatient peer support to develop an in-depth understanding of the influence during the rehabilitation journey. In 2011, twenty-one burn survivors were recruited from four severe burn units across Australia. A qualitative phenomenological methodology was used to construct themes depicting survivors' experiences. Participants were selected through purposeful sampling, and data collected through in-depth individual semi-structured interviews. Data were analysed using Colaizzi's phenomenological method of data analysis. Central to burn rehabilitation was the notion of peer support having a significant impact on burn survivors' psychosocial rehabilitation. The emergent theme 'Burn Survivor Peer Support' identified five cluster themes: (1) Encouragement, inspiration and hope (2) Reassurance (3) The Importance of Timing (4) The Same Skin (5) Appropriate Matching. These findings demonstrate that peer support assists with fostering reassurance, hope and motivation in burn rehabilitation. A national network based on a clinician led inpatient burn survivor peer support programme could provide burn survivors across Australia, and in particular remote access locations, with the benefits of peer support necessary to endure the rehabilitation journey.

    The great Sichuan earthquake in China on May 12, 2008 was a traumatic event to many who live near the earthquake area. However, at present, there are few studies that explore the long-term impact of the adolescent trauma exposure on adults' brain function. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate the brain activation evoked by masked trauma-related stimuli (earthquake versus neutral images) in 14 adults who lived near the epicenter of the great Sichuan earthquake when they were adolescents (trauma-exposed group) and 14 adults who lived farther from the epicenter of the earthquake when they were adolescents (control group). Compared with the control group, the trauma-exposed group showed significant elevation of activation in the right anterior cingulate cortex (ACC) and the medial prefrontal cortex (MPFC) in response to masked earthquake-related images. In the trauma-exposed group, the right ACC activation was negatively correlated with the frequency of symptoms of post-traumatic stress disorder (PTSD). These findings differ markedly from the long-term effects of trauma exposure in adults. This suggests that trauma exposure during adolescence may have a unique long-term impact on ACC/MPFC function, top-down modulation of trauma-related information, and subsequent symptoms of PTSD.

    Videos with rich social and emotional content elicit natural social behaviors in primates. Indeed, while watching videos of conspecifics, monkeys engage in eye contact, gaze follow, and reciprocate facial expressions. We hypothesized that the frequency and timing of eyeblinks also depends on the social signals contained in videos. We monitored the eyeblinks of four male adult macaques while they watched videos of conspecifics displaying facial expressions with direct or averted gaze. The instantaneous blink rate of all four animals decreased during videos. The temporal synchrony of blinking, however, increased in response to segments depicting appeasing or aggressive facial expressions directed at the viewer. Two of the four monkeys, who systematically reciprocated the direct gaze of the stimulus monkeys, also showed eyeblink entrainment, a temporal coordination of blinking between social partners engaged in dyadic interactions. Together, our results suggest that in macaques, as in humans, blinking depends not only on the physiological imperative to protect the eyes and spread a film of tears over the cornea, but also on several socio-emotional factors.

    A retrospective analytical study examined the records of 220 adult males (mean age 64.9 years) to determine the relative probability that multiple urine culture isolates (MUI) represent urinary tract infection (UTI) versus contamination or colonization. Nonculture laboratory data were used to determine the likelihood of UTI. Patients were classified into three categories: group 1 (those with single isolate cultures; n = 110), group 2 (those with MUI and either symptomatic UTI or an underlying pathologic condition; n = 71) and group 3 (those with MUI and either surgically altered urinary passages or absence of UTI symptoms; n = 39). Nonculture laboratory data suggested UTI in 48.2% of patients in group 1, 46.5% in group 2, and 23.1% in group 3. Patients in groups 1 or 2 with cultures yielding isolate counts of 10(5) colony forming units/mL were 6.2 times more likely to be classified as having a UTI (by nonculture laboratory data) compared with patients having only one or more of these two criteria. This study proposes a more objective approach to interpretation of MUI cultures using the results of nonculture laboratory data, clinical profiles, and colony counts. PMID:7897687

    Adult male patients affected with Becker (BMD, N = 22), limb girdle (LGMD, N = 22) and facioscapulohumeral (FSHMD, N = 18) muscular dystrophy were interviewed to assess for the first time how the disease's severity and recurrence risk (RR) magnitude alter their social adjustment. BMD (X-linked recessive) is the severest form and confers an intermediate RR because all daughters will be carriers, LGMD (autosomal-recessive) is moderately severe with a low RR in the absence of consanguineous marriage, and FSHMD (autosomal-dominant) is clinically the mildest of these three forms of MD but with the highest RR, of 50%. Results of the semistructured questionnaire [WHO (1988): Psychiatric Disability Assessment Schedule] showed no significant difference between the three clinical groups, but more severely handicapped patients as well as patients belonging to lower socioeconomic levels from all clinical groups showed poorer social adjustment. Taken together, myopathic patients displayed intermediate social dysfunction compared to controls and schizophrenics studied by Jablensky [1988: WHO Psychiatric Disability Assessment Schedule]. Since the items of major dysfunction proportion among myopathic patients concern intimate relationships (70%), interest in working among those unemployed (67%), and social isolation (53%), emotional support and social and legal assistance should concentrate on these aspects. Interestingly, the results of this study also suggest that high RRs do not affect relationships to the opposite sex.

    2010-01-01

    Purpose Despite the surge in scholarly activity investigating the criminal career, relatively less attention has been devoted to the issue of criminal desistance versus persistence (until recently). The present study contributed to our understanding of this process by exploring the suitability of General Strain Theory (GST) for predicting changes in criminal activity across time. Methods Data from a longitudinal study of males in South Florida are examined using robust regression analyses. Results The core GST relationship, that changes in strain should predict changes in criminal activity, was supported, even after controlling for important adult social roles such as marriage, labor force participation, and education. While no support for the proposition that changes in self-esteem and social support moderate the strain-criminal desistance association was evinced, evidence was found that angry disposition, a measure of negative emotionality, moderated the association between change in chronic stressors and change in criminal activity. Conclusions While exploratory in nature, these findings demonstrate the utility of employing GST principles in studies of criminal desistance. PMID:21499526

    Nicotine dependence is a significant public health problem. This study describes the nicotine dependence status among male adults in rural communities in Egypt. A survey was carried out in five rural villages in Egypt to study the smoking prevalence. A total of 938 current smokers were identified and their nicotine dependence status was studied. About 9% of all smokers in the studied villages were found to have heavy dependence to nicotine. Heavy dependence was associated with younger age of smoking initiation (p<0.05) and more smoking in the first hours of the day (p<0.001). Heavy dependent smokers are less likely to quit smoking (p<0.001), lack the confidence to quit by themselves (p<0.001) and less likely to have tried to quit earlier (p<0.001). Dependent smokers are more likely to smoke in the presence of their children (p<0.001). Reasons for smoking included the habit of smoking helping them to keep them going when tired, to make them alert and not knowing what to do with their hands without a cigarette. The main reasons they identified for restarting smoking after quitting were the signs of withdrawal namely headaches, irritability and difficulty in concentration. Nicotine dependence status and attributes were comparable to studies reported in other countries around the world. Enhanced behavioral and medical intervention strategies are needed to motivate helping both low and heavy nicotine dependent smokers to increase the number and effectiveness of quit attempts.

    Due to toxicities associated with their malignancies and treatments, adolescent and young adult survivors of childhood cancer (AYASCC) are at high risk for developing chronic diseases. This can be compounded by a greater prevalence of unhealthy behaviors relative to similarly aged non-cancer peers. Disparities in health behaviors have been noted for Black and Hispanic AYASCC, but data on Asian American (AA) or Native Hawaiian and Other Pacific Islander (NHOPI) minorities are lacking. The purpose of this study was to help bridge these information gaps by gathering data from Hawai'i AA and NHOPI AYSCC. Telephone surveys were used to collect health behavior data from survivors 13-24 years of age (N=64); 55% of the sample was female, 77% AA or NHOPI, 63% leukemia/lymphoma survivors, and 32% overweight/obese. These were compared to state/national survey data for similarly aged individuals (Youth Risk Behavior Surveillance System data for 13-17 year olds, and Behavioral Risk Factor Surveillance System data for 18-24 year olds). While Hawai'i AYASCC had significantly lower rates of tobacco/alcohol use, a higher proportion did not eat five fruits/vegetables a day (96%) compared to state (83%) and national (78%) samples (P < .001). Although many met age-specific physical activity recommendations, 44% of <18 year olds and 29% of ≥18 year olds still failed to meet national guidelines. Low intake of fruits/vegetables and suboptimal levels of physical activity place these vulnerable, ethnic minority cancer survivors at higher risk for chronic disease. These findings underscore the need to assess and advise survivors about their diet and exercise habits as part of post-treatment care.

    Traumatic brain injury (TBI) is a common cause of childhood disability, and is associated with elevated risk for long-term social impairment. Though social (pragmatic) communication deficits may be among the most debilitating consequences of childhood TBI, few studies have examined very long-term communication outcomes as children with TBI make the transition to young adulthood. In addition, the extent to which reduced social function contributes to externalizing behaviors in survivors of childhood TBI remains poorly understood. The present study aimed to evaluate the extent of social communication difficulty among young adult survivors of childhood TBI (n=34, injury age: 1.0-7.0 years; M time since injury: 16.55 years) and examine relations among aspects of social function including emotion perception, social communication and externalizing behaviors rated by close-other proxies. Compared to controls the TBI group had significantly greater social communication difficulty, which was associated with more frequent externalizing behaviors and poorer emotion perception. Analyses demonstrated that reduced social communication mediated the association between poorer emotion perception and more frequent externalizing behaviors. Our findings indicate that socio-cognitive impairments may indirectly increase the risk for externalizing behaviors among young adult survivors of childhood TBI, and underscore the need for targeted social skills interventions delivered soon after injury, and into the very long-term.

    Although studies have explored the 'lived experience' of burn survivors, little is known about their experiences encountered during rehabilitation. A descriptive phenomenological study was conducted to gain an in-depth insight into burn survivors' experiences' of acknowledgement and acceptance of their injury and the challenges experienced during their rehabilitation journey. A descriptive phenomenological methodology was used to construct themes depicting how burn survivors endeavoured to acknowledge and accept their injury and subsequent altered body image. Twenty men and one woman up to eight years after-burn within Australia were selected through purposeful sampling, and data were collected through in-depth individual interviews conducted in 2011 (N = 21). Interviews were analysed using Colaizzi's method of data analysis. The emergent theme acknowledgement identified four cluster themes that represented how burn survivors came to terms with their injury and an altered body image: (1) reasoning (2) humour (3) the challenge of acceptance (4) self-awareness. Coming to terms with a severe burn is a challenging experience. Reasoning and humour are strategies utilised by burn survivors that facilitate with acknowledgement and acceptance. Understanding these concepts through the burn survivors' perspective will, potentially, facilitate a better understanding of how to best provide for this cohort of patients.

    Background Healthcare self-efficacy (HCSE), the perceived confidence to manage one’s health care, has been identified as a critical component in the transition process from pediatric to adult-oriented care for childhood cancer survivors (CCSs). HCSE is amenable to intervention and associated with long-term follow-up care among CCSs. However, factors associated with HCSE have not been fully explored among CCSs. Procedure We identified correlates of HCSE among a sample of CCSs (n = 193). Descriptive statistics and linear regression methods were used in this cross-sectional analysis. Results In univariate analyses, higher physical and psychosocial quality of life, posttraumatic growth, and religious/spiritual importance were associated with higher HCSE. Attendance at a survivorship clinic, having a regular source of care (both noncancer and oncologist), and any type of health insurance were also associated with HCSE. Hispanic ethnicity was negatively associated with HCSE relative to non-Hispanics. In a multivariable model, psychosocial quality of life, religious/spiritual importance, survivorship clinic attendance, having a regular oncologist, and Hispanic ethnicity remained significantly associated with HCSE. Conclusions CCSs who reported greater well-being, who rated religion and spirituality of high importance, and who accessed specialized cancer services expressed greater HCSE. Hispanic CCSs, however, reported less HCSE than non-Hispanics. Interventions that attend to the quality of life and spiritual needs of CCSs have potential to build HCSE to support the healthcare transition process. Because Hispanic CCSs may be at risk of lower perceived confidence to navigate their health care, culturally competent, efficacy-enhancing interventions are needed for this population. PMID:27567026

    Background We previously noted that among atomic bomb survivors (ABS), the relative frequency of cases of adult papillary thyroid cancer (PTC) with chromosomal rearrangements (mainly RET/PTC) was significantly greater in those with relatively higher radiation exposure than those with lower radiation exposure. In contrast, the frequency of PTC cases with point mutations (mainly BRAFV600E) was significantly lower in patients with relatively higher radiation exposure than those with lower radiation exposure. We also found that among ABS, the frequency of PTC cases with no detectable gene alterations in RET, neurotrophic tyrosine kinase receptor 1 (NTRK1), BRAF, or RAS was significantly higher in patients with relatively higher radiation exposure than those with lower radiation exposure. However, in ABS with PTC, the relationship between the presence of the anaplastic lymphoma kinase (ALK) gene fused with other gene partners and radiation exposure has received little study. In this study, we tested the hypothesis that the relative frequency of rearranged ALK in ABS with PTC, and with no detectable gene alterations in RET, NTRK1, BRAF, or RAS, would be greater in those having relatively higher radiation exposures. Methods The 105 subjects in the study were drawn from the Life Span Study cohort of ABS of Hiroshima and Nagasaki who were diagnosed with PTC between 1956 and 1993. Seventy-nine were exposed (>0 mGy), and 26 were not exposed to A-bomb radiation. In the 25 ABS with PTC, and with no detectable gene alterations in RET, NTRK1, BRAF, or RAS, we examined archival, formalin-fixed, paraffin-embedded PTC specimens for rearrangement of ALK using reverse transcription–polymerase chain reaction and 5′ rapid amplification of cDNA ends (5′ RACE). Results We found rearranged ALK in 10 of 19 radiation-exposed PTC cases, but none among 6 patients with PTC with no radiation exposure. In addition, solid/trabecular-like architecture in PTC was closely associated with ALK

    Owl monkeys (Aotus azarai) are small, territorial, socially monogamous primates that show intense infant care by the adult male in the group. It has been hypothesized that male care may be adaptive because it increases offspring survival and/or reduces the metabolic costs to the female of raising the offspring. Alternatively, males may provide care even when they are not related to the infants to increase future reproductive opportunities. We describe changes in infant care patterns that took place after the eviction of the resident male by a solitary male in an owl monkey population in the Argentinean Chaco. The resident male and mother provided all infant care during the first month of life of the infant, until the male was evicted. During the three-day male replacement event, care of the infant was shared among the mother, a four-year-old sister, and a one-year-old brother. The new male began contributing to infant care soon after entering the group, carrying, and interacting socially with the infant in much the same way as any male regularly does. However, despite receiving biparental care from both the original and new resident males, the infant disappeared at the age of four months and was presumed dead. These are the first reports of care by sibling and by non-putative fathers in wild owl monkeys. Given the significant amount of time that new pairs of owl monkeys spend before reproducing, it is possible that male care in owl monkeys functions as mating effort as much as or more than parenting effort.

    In this study, we identified the differentially expressed proteins of female and male adults of Angiostrongylus cantonensis through differential proteomics. We extracted and purified total proteins from male and female adults, separated proteins by two-dimensional difference gel electrophoresis (2D-DIGE) in pH 4-7, analyzed the gel images by DeCyder 7.0 software, and sacrificed the infected rats to count the number of male and female adults. It was found 28 protein spots that were differentially expressed; seven protein spots were then identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Five proteins were up-regulated and two proteins down-regulated in male adults compared with female adults. Three of the five up-regulated proteins with known functions ascribed to them were identified as galectin-1, proteasome alpha subunit and peroxiredoxin. The two down-regulated proteins were identified as indoleamine dioxygenase like-myoglobin and galectin. Furthermore, the female was significantly greater than male adults (P<0.01) in the rats. The findings demonstrate the differences in protein expression profiles and the ability to survive in the final host between female and male adults of A. cantonensis, and may provide a theoretical basis to study their developmental biology further.

    Yolk polypeptide (YP) synthesis is hormonally stimulated during maturation of adult female Drosophila melanogaster. Synthesis of the three YPs is sex specific and occurs in fat body cells and follicle cells of adult females. However, males have been shown to produce YPs when treated with the steroid hormone 20-hydroxyecdysone (20-HE). By using a cell-free translation system as an assay for YP mRNA, we found that 20-HE also causes the accumulation of translatable YP message in males. In addition, hybridization of cloned copies of genes for both YP1 and YP3 to total RNA from males showed that 20-HE caused the appearance of YP gene transcripts in males. Eight hours after treatment of males with 20-HE, YP gene transcript levels had increased at least 25-fold to approximately 2.7 x 10(6) copies of YP1 gene transcript per adult male fly. In normal adult females, there were 42 x 10(6) copies per fly by 24 hr. There was neither detectable YP synthesis nor translatable YP gene transcript in either normal 1- to 3-day-old males or 24-hr-old males treated with a juvenile hormone analogue. This evidence shows that 20-HE acts to regulate the levels of translatable YP mRNA in male Drosophila.

    Media and service provider reports of sexual and gender based violence (SGBV) perpetrated against men in armed conflicts have increased. However, response to these reports has been limited, as existing evidence and programs have primarily focused on prevention and response to women and girl survivors of SGBV. This study aims to contribute to the evidence of SGBV experienced by males by advancing our understanding of the definition and characteristics of male SGBV and the overlap of health, social and economic consequences on the male survivor, his family and community in conflict and post-conflict settings. The qualitative study using purposive sampling was conducted from June-August 2010 in the South Kivu province of Eastern DRC, an area that has experienced over a decade of armed conflict. Semi structured individual interviews and focus group discussions were conducted with adult male survivors of SGBV, the survivors' wife and/or friend, health care and service providers, community members and leaders. This study found that SGBV against men, as for women, is multi-dimensional and has significant negative physical, mental, social and economic consequences for the male survivor and his family. SGBV perpetrated against men and boys is likely common within a conflict-affected region but often goes unreported by survivors and others due to cultural and social factors associated with sexual assaults, including survivor shame, fear of retaliation by perpetrators and stigma by community members. All key stakeholders in our study advocated for improvements and programs in several areas: (1) health care services, including capacity to identify survivors and increased access to clinical care and psychosocial support for male survivors; (2) economic development initiatives, including microfinance programs, for men and their families to assist them to regain their productive role in the family; (3) community awareness and education of SGBV against men to reduce stigma and

    Purpose This guideline presents screening, assessment, and treatment approaches for the management of adult cancer survivors who are experiencing symptoms of fatigue after completion of primary treatment. Methods A systematic search of clinical practice guideline databases, guideline developer Web sites, and published health literature identified the pan-Canadian guideline on screening, assessment, and care of cancer-related fatigue in adults with cancer, the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines In Oncology (NCCN Guidelines) for Cancer-Related Fatigue and the NCCN Guidelines for Survivorship. These three guidelines were appraised and selected for adaptation. Results It is recommended that all patients with cancer be evaluated for the presence of fatigue after completion of primary treatment and be offered specific information and strategies for fatigue management. For those who report moderate to severe fatigue, comprehensive assessment should be conducted, and medical and treatable contributing factors should be addressed. In terms of treatment strategies, evidence indicates that physical activity interventions, psychosocial interventions, and mind-body interventions may reduce cancer-related fatigue in post-treatment patients. There is limited evidence for use of psychostimulants in the management of fatigue in patients who are disease free after active treatment. Conclusion Fatigue is prevalent in cancer survivors and often causes significant disruption in functioning and quality of life. Regular screening, assessment, and education and appropriate treatment of fatigue are important in managing this distressing symptom. Given the multiple factors contributing to post-treatment fatigue, interventions should be tailored to each patient's specific needs. In particular, a number of nonpharmacologic treatment approaches have demonstrated efficacy in cancer survivors. PMID:24733803

    In the house mouse (Mus musculus), fetuses may develop in utero next to siblings of the same or opposite sex. The amniotic fluid of the female fetuses contains higher concentrations of estradiol than that of male fetuses. Male fetuses that developed in utero between female fetuses had higher concentrations of estradiol in their amniotic fluid than males that were located between other male fetusesw during intrauterine development. They were also more sexually active as adults, less aggressive, and had smaller seminal vesicles than males that had developed between other male fetuses in utero. These findings raise the possibility that during fetal life circulating estrogens may interact with circulating androgens both in regulating the development of sex differences between males and females and in producing variation in phenotype among males and among females.

    Eight groups of male adolescent and adult spontaneous hyperactive rats (SHR) were used in a dose response (saline, 0.6, 2.5, and 10 mg/kg) experiment of methylphenidate (MPD). Four different locomotor indices were recorded for 2 hours postinjection using a computerized monitoring system. Acutely, the 0.6 mg/kg dose of MPD did not elicit an increase in locomotor activity in either the adolescent or in the adult male SHR. The 2.5 and the 10.0 mg/kg doses increased activity in the adolescent and the adult rats. Chronically, MPD treatment when comparing adolescent and adult gave the following results: the 0.6 mg/kg dose of MPD failed to cause sensitization in the adolescent group but caused sensitization in the adult group, while the 2.5 and 10 mg/kg both caused sensitization in the adolescent and adult groups.

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

    Purpose To assess the prevalence and severity of neurocognitive impairment in adult survivors of pediatric CNS tumors and to examine associated treatment exposures. Patients and Methods Participants included 224 survivors of CNS tumors who were treated at St Jude Children's Research Hospital (current median age [range], 26 years [19 to 53 years]; time from diagnosis, 18 years [11 to 42 years]) and completed neurocognitive testing. Information on cranial radiation therapy (CRT) doses and parameters of delivery were abstracted from medical records. The prevalence of severe impairment (ie, at least two standard deviations below normative mean) was compared across radiation treatment groups (no CRT, focal irradiation, craniospinal irradiation) using the χ2 test. Log-binomial models were used to estimate risk ratios (RRs) and corresponding 95% CIs for severe impairment. Results In multivariable models, craniospinal irradiation was associated with a 1.5- to threefold increased risk of severe impairment compared with no CRT (eg, intelligence: RR = 2.70; 95% CI, 1.37 to 5.34; memory: RR = 2.93; 95% CI, 1.69 to 5.08; executive function: RR = 1.74; 95% CI, 1.24 to 2.45). Seizures were associated with impaired academic performance (RR = 1.48; 95% CI, 1.02 to 2.14), attention (RR = 1.54; 95% CI, 1.12 to 2.13), and memory (RR = 1.44; 95% CI, 1.04 to 1.99). Hydrocephalus with shunt placement was associated with impaired intelligence (RR = 1.78; 95% CI, 1.12 to 2.82) and memory (RR = 1.42; 95% CI, 1.03 to 1.95). Differential follow-up time contributed to variability in prevalence estimates between survivors treated with older nonconformal and those treated with more contemporary conformal radiation therapy methods. Neurocognitive impairment was significantly associated with lower educational attainment, unemployment, and nonindependent living. Conclusion Survivors of pediatric CNS tumors are at risk of severe neurocognitive impairment in adulthood. The prevalence of severe

    Young adult childhood cancer survivors are at increased risk for frailty, a physiologic phenotype typically found among older adults. This phenotype is associated with new onset chronic health conditions and mortality among both older adults and among childhood cancer survivors. Mounting evidence suggests that poor fitness, muscular weakness and cognitive decline are common among adults treated for childhood malignancies, and that risk factors for these outcomes are not limited to those treated with cranial radiation. Although the pathobiology of this phenotype is not known, early cellular senescence, sterile inflammation and mitochondrial dysfunction in response to initial cancer or treatment related insults are hypothesized to play a role. Interventions to prevent or remediate frailty among childhood cancer survivors have not been tested. Pharmaceutical, nutriceutical and lifestyle interventions show some promise. PMID:25529481

    Troops comprising a high density population of samango monkeys (Cercopithecus mitis) in Natal province, South Africa, experienced an influx of adult males during the breeding season. Observation of one troop revealed that these males competed with one another and with two resident males for access to receptive females. Although both sexes initiated copulation, attempts to do so were more often successful if female-initiated. Males did not interact with non-receptive females and there were no recorded attempts at infanticide. Male-male interactions were agonistic in the presence of receptive females and neutral at other times. No ritualized displays of dominance and subordinance were seen. The significance of these observations for male reproductive strategies is discussed.

    Introduction: Our aim was to investigate the psychological and sexual effects of circumcision in adult men, and analyze these changes following circumcision. Methods: We included 37 adults who applied to our clinic for circumcision and who did not have any psychiatric or urologic disorders and age-matched 30 controls in our study. Body Cathexis Scale (BCS), Liebowitz Social Anxiety Scale (LSAS), and Premature Ejaculation Diagnostic Tool (PEDT) were applied to the study group twice, once before and once three months after circumcision, and only once in the control group. Also, intravaginal ejaculation latency time (IELT) was noted and premature ejaculation (PE) evaluation was done. Intra- and intergroup comparisons were performed. Results: The two groups were similar with regard to demographic data. Comparison of preoperative BCS and LSAS scores with the scores of the control group showed significant differences (p=0.003, p<0.001, and p<0.001, respectively). However, postoperative scores were similar to the scores obtained in the control group (p=0.768, p>0.05, and p>0.05, respectively). Scores of all scales showed significant improvements postoperatively. Also, PEDT scores and IELT changes before and after circumcision were significant in the study group, but not when compared to the control group. Conclusions: Our results indicated that social anxiety and anxiety levels decreased after circumcision in adult Turkish men, and their body gratification increased. We found that not being circumcised might negatively affect individuals in adulthood when it comes to body image and sexual satisfaction, however, both improve after circumcision. PMID:27790295

    Using voxel-based morphometry, we measured the cerebral anatomical asymmetries in a sample of 56 young right-handed males and then compared voxelwise asymmetry indices of these subjects to those of 56 young left-handed males. In the right-handed, the clusters of grey matter asymmetry corresponding to the leftward occipital petalia and planum temporale asymmetries were retrieved. Strong rightward temporo-parietal asymmetries were also observed, but the rightward grey matter asymmetry in the frontal lobe was less massive than previously described. Group comparisons of left- and right-handed subjects' asymmetry maps, performed at a statistical threshold not corrected for multiple comparisons, revealed significant effects of handedness on this pattern of anatomical asymmetry in frontal regions, notably in the lower central and precentral sulci, and also in the planum temporale, with right-handed subjects being more leftward asymmetric. Concerning white matter, although almost no focal differences between left- and right-handed subjects were detected, volumetric analyses at the hemispheric level revealed a leftward asymmetry, which happened to be significantly less marked in the left-handed. This latter result, together with the pattern of leftward white matter asymmetries, suggested that anatomical correlates of the left hemispheric specialization for language would exist in white matter. In the population we studied, differences in anatomical asymmetry between left- and right-handed subjects provided structural arguments for a greater functional ambilaterality in left-handed subjects.

    This research aimed to compare the prevalence rates of major depressive disorder (MDD) and to differentiate the presence and severity of depressive symptoms between women and men aged 18-24 years. In this population-based, cross-sectional study (n = 1560), young adults were screened with the Mini International Neuropsychiatric Interview for MDD (n = 137). Participants then completed a self-report questionnaire to gather sociodemographic data, and the presence of each symptom of depression was assessed with the Beck Depression Inventory. The proportion of women (12.2%) with MDD was higher than that of men (5.3%). The symptoms of depression found to be significantly more prevalent in women were sadness, crying, difficulty making decisions, and lack of energy, as well as self-criticism, irritability, changes in self-image, work difficulty, and loss of interest in sex. Sadness and self-criticism were significantly more severe in women than in men. The presentation of depressive symptoms in young adults with MDD differed between men and women.

    Purpose Frailty, a phenotype reported among 9.9% of individuals 65 years old and older (9.6% of women; 5.2% of men), has not been assessed among adult childhood cancer survivors (CCS). We estimated the prevalence of frailty and examined associations with morbidity and mortality. Methods Participants included 1,922 CCS at least 10 years from original cancer diagnosis (men, 50.3%; mean age, 33.6 ± 8.1 years) and a comparison population of 341 participants without cancer histories. Prefrailty and frailty were defined as two and ≥ three of the following conditions: low muscle mass, self-reported exhaustion, low energy expenditure, slow walking speed, and weakness. Morbidity was defined as grade 3 to 4 chronic conditions (Common Terminology Criteria for Adverse Events version 4.0). Fisher's exact tests were used to compare, by frailty status, percentages of those with morbidity. In a subset of 162 CCS who returned for a second visit, Poisson regression was used to evaluate associations between frailty and new onset morbidity. Cox proportional hazards regression was used to evaluate associations between frailty and death. Results The prevalence of prefrailty and frailty were 31.5% and 13.1% among women and 12.9% and 2.7% among men, respectively, with prevalence increasing with age. Frail CCS were more likely than nonfrail survivors to have a chronic condition (82.1% v 73.8%). In models adjusted for existing chronic conditions, baseline frailty was associated with risk of death (hazard ratio, 2.6; 95% CI, 1.2 to 6.2) and chronic condition onset (relative risk, 2.2; 95% CI, 1.2 to 4.2). Conclusion The prevalence of frailty among young adult CCS is similar to that among adults 65 years old and older, suggesting accelerated aging. PMID:24248696

    Autoimmune enteropathy (AIE) is rare but damaging. The lack of consistent objective findings makes diagnosis a challenge. A 45-year-old male developed noninfectious diarrhea with significant weight loss and electrolyte abnormalities. Computed tomography delineated enteritis. Colonoscopy and esophagogastroduodenoscopy showed villous atrophy, chronic inflammation, and ulceration of the terminal ileum and cecum. Pathology showed cryptitis with apoptosis and abscesses throughout the small and large bowel and absent goblet cells. Steroids rapidly improved symptoms. Anti-enterocyte antibody serologies were negative. Management can be challenging, and, in this case, the patient initially improved with budesonide and infliximab but required alternative anti-tumor necrosis factor therapy after relapsing. This is an unusual presentation of seronegative AIE, which should be considered in cases of persistent severe diarrhea. PMID:28184376

    Interviews with seven of ten known survivors of jumps from the Golden Gate and San Francisco-Oakland Bay bridges showed a unique association between the Golden Gate Bridge and suicide. The study went beyond exploring the nature of suicidal jumps and shed new light on the experience of nearly dying. All the survivors described this experience as tranquil and peaceful. None of them experienced life events or distant memories passing through their minds or before their eyes. However, all of them experienced transcendence and spiritual rebirth phenomena. Suggestions for preventing suicides from the Golden Gate Bridge are discussed, including the construction of a suicide barrier. PMID:1171558

    We describe a 20-year-old man diagnosed with a myelodysplastic syndrome (MDS), admitted to our hospital due to pancytopenia and fever of undetermined origin after myelosuppression with chemotherapy. Disseminated aspergillosis (DIA) was suspected when he developed skin and lung involvement. A rapidly growing mass was detected on the left neck area, during hospitalization. A thyroid ultrasound reported a 3.7 × 2.5 × 2.9 cm oval heterogeneous structure, suggestive of an abscess versus a hematoma. Fine needle aspiration of the thyroid revealed invasion of aspergillosis. Fungal thyroiditis is a rare occurrence. Thyroid fungal infection is difficult to diagnose; for this reason it is rarely diagnosed antemortem. To our knowledge, this is the 10th case reported in the literature in an adult where the diagnosis of fungal invasion to the thyroid was able to be corroborated antemortem by fine needle aspiration biopsy.

    Based on the Chinese reference adult male voxel model, a set of microscopic skeletal models of Chinese adult male is constructed through the processes of computed tomography (CT) imaging, bone coring, micro-CT imaging, image segmentation, merging into macroscopic bone model and implementation in Geant4. At the step of image segmentation, a new bone endosteum (BE) segmentation method is realized by sampling. The set of model contains 32 spongiosa samples with voxel size of 19 μm cubes. The microscopic spongiosa bone data for Chinese adult male are provided. Electron absorbed fractions in red bone marrow (RBM) and BE are calculated. Source tissues include the bone marrow (red and yellow), trabecular bone (surfaces and volumes) and cortical bone (surfaces and volumes). Target tissues include RBM and BE. Electron energies range from 10 keV to 10 MeV. Additionally, comparison of the result with other investigations is provided.

    The morphometric method of forensic facial reconstruction rests heavily on the use of facial soft tissue depth measurements. In reconstructing the Negroid face, much use has been made of the tables of soft tissue thickness of American Negroid cadavers. However, the genetic complexities of American blacks are well known. In addition it is felt that measurements made on the living are of more value than those made on the dead. In view of this it was decided to set up a table of norms for facial soft tissue depths of the living Zulu, an African Negroid who has remained relatively free from genetic admixture with other populations. The tightly controlled sample consisted of 55 healthy male Zulus, aged 20 to 35. Tissue depths at established landmarks were measured from lateral and oblique cephalometric radiographs. These were then combined with ultrasonic readings at other landmarks on the subject's face to yield a comprehensive set of tissue depth data. This paper presents a set of average facial soft tissue depth measurements from the Zulu face that results in the development of a new profile. It also provides a method for linking two systems of measurement.

    This study investigated the acute effects of oxytocin (OT) on human aggression using a well-established laboratory measure of state (reactive) aggression to test the hypothesis that OT would decrease the frequency of aggressive responding. In a within-subject design, 17 healthy male volunteers received placebo or 24 international units of intranasal OT. Aggression was measured via the Point Subtraction Aggression Paradigm at 30 min prior and 30, 60 and 90 min post-dose. Acute OT did not produce a significant main effect on aggressive behavior. OT attenuated the expected rise in diastolic blood pressure from morning to early afternoon observed under placebo, providing a possible indicator of biological activity. Examination of individual differences showed that aggressive responding following OT dosing (but not placebo) was positively correlated with psychometric measures of interpersonal manipulation and anger (Pearson’s r = 0.57), indicating that higher scores on these antisocial personality traits were related to increased aggressive behavior following OT administration. These preliminary results stand in contrast to previous work on the prosocial effects of OT and highlight the need for further understanding of individual differences in aggression following OT administration. Such individual differences may have implications for the therapeutic use of OT in individuals with psychiatric disorders and dysfunctional social behavior. PMID:26241153

    A large survey of patients hospitalized for kidney stones in the Carolinas and the Rocky Mountain states yielded information that can be translated into conservative estimates of cost of this disease. Hospital costs were estimated by considering number of surgeries, the approximate cost of various types of surgery, number of days hospitalized, and room rates. Work force costs were estimated from information on work days lost and income categories. Estimated recurrence rates for this disease are used to approximate the total cost, due to stones, for the next year for a current stone case. Each incident of stone disease costs, on the average, approximately $2,000, exclusive of recurrences. Hospital stays average four to five days. The average annual cost of recurrence for a current stone case is conservatively estimated to be in the $300 to $400 range. A conservative projection of these costs to the entire national population of white males in the age range of eighteen to sixty years yields an annual cost due to kidney stones approaching $315,000,000.

    Recent experiments have shown that sexual interactions prior to cell proliferation cause an increase in neurogenesis in adult male rats. Because adult neurogenesis is critical for some forms of memory, we hypothesized that sexually induced changes in neurogenesis may be involved in mate recognition. Sexually naive adult male rats were either exposed repeatedly to the same sexual partner (familiar group) or to a series of novel sexual partners (unfamiliar group), while control males never engaged in sexual interactions. Ovariectomized female rats were induced into estrus every four days. Males were given two injections of 5-bromo-2'-deoxyuridine (BrdU) (200mg/kg) to label proliferating cells, and the first sexual interactions occurred three days later. Males in the familiar and unfamiliar groups engaged in four, 30-min sexual interactions at four-day intervals, and brain tissue was collected the day after the last sexual interaction. Immunohistochemistry followed by microscopy was used to quantify BrdU-labeled cells. Sexual interactions with unfamiliar females caused a significant reduction in neurogenesis in the dentate gyrus compared to males that interacted with familiar females and compared to the control group. The familiar group showed no difference in neurogenesis compared to the control group. Males in the familiar group engaged in significantly more sexual behavior (ejaculations and intromissions) than did males in the unfamiliar group, suggesting that level of sexual activity may influence neurogenesis levels. In a second experiment, we tested whether this effect was unique to sexual interactions by replicating the entire procedure using anestrus females. We found that interactions with unfamiliar anestrus females reduced neurogenesis relative to the other groups, but this effect was not statistically significant. In combination, these results indicate that interactions with unfamiliar females reduce adult neurogenesis and the effect is stronger for sexual

  8. Seasonal androgen cycles in adult male American alligators (Alligator mississippiensis) from a barrier island population.

    The seasonal patterns of two primary plasma androgens, testosterone (T) and dehydroepiandrosterone (DHEA), were assessed in adult male alligators from the Merritt Island National Wildlife Refuge, a unique barrier island environment and home to the Kennedy Space Center in Florida. Samples were collected monthly from 2008 to 2009, with additional samples collected at more random intervals in 2007 and 2010. Plasma T concentrations peaked in April, coincident with breeding and courtship, and declined rapidly throughout the summer. Seasonal plasma T patterns in smaller though reproductively active adult males differed from those in their larger counterparts during the breeding season. Both size classes showed significant increases in plasma T concentration from February to March, at the beginning of the breeding season. However, smaller adults did not experience the peak in plasma T concentrations in April that were observed in larger adults, and their concentrations were significantly lower than those of larger males for the remainder of the breeding season. Plasma DHEA concentrations peaked in May and were significantly reduced by June. This is the first study to demonstrate the presence of DHEA in a crocodilian, and the high plasma DHEA concentrations that paralleled the animals' reproductive activity suggest a reproductive and/or behavioral role in adult male alligators. Similar to androgen variations in some birds, plasma DHEA concentrations in the alligators were considerably higher than T concentrations during the nonbreeding season, suggesting a potential role in maintaining nonbreeding seasonal aggression.

    The aim of the present study was to examine the cross-sensitization induced by prenatal methamphetamine (MA) exposure to adult amphetamine (AMP) treatment in male and female rats. Rat mothers received a daily injection of MA (5 mg/kg) or saline throughout the gestation period. Adult male and female offspring (prenatally MA- or saline-exposed) were administered with AMP (5 mg/kg) or saline (1 ml/kg) in adulthood. Behaviour in unknown environment was examined in open field test (Laboras), active drug-seeking behaviour in conditioned place preference test (CPP), spatial memory in the Morris water maze (MWM), and levels of corticosterone (CORT) were analyzed by enzyme immunoassay (EIA). Our data demonstrate that in Laboras test, AMP treatment in adulthood increased general locomotion (time and distance travelled) regardless of the prenatal exposure and sex, while AMP increased exploratory activity (rearing) only in prenatally MA-exposed animals. AMP induced sensitization only in male rats, but not in females when tested drug-seeking behaviour in the CPP test. In the spatial memory MWM test, AMP worsened the performance only in females, but not in males. On the other hand, males swam faster after chronic AMP treatment regardless of the prenatal drug exposure. EIA analysis of CORT levels demonstrated higher level in females in all measurement settings. In males, prenatal MA exposure and chronic adult AMP treatment decreased CORT levels. Thus, our data demonstrated that adult AMP treatment affects behaviour of adult rats, their spatial memory and stress response in sex-specific manner. The effect is also influenced by prenatal drug exposure.

    The aim of this study was to characterize the vocalizations produced during electroejaculation under general anaesthesia in pampas deer males and to determine whether the characteristics of those vocalizations differ in adult and young pampas deer males. Electroejaculation was applied to 13 adults (AM) and 13 young (YM) males under general anaesthesia. Vocalizations were digitally recorded, and the number and duration of vocalizations, the latency in relation to each voltage, the total time vocalizing, and the structure of the fundamental frequency (F0) [initial frequency (F(start)), maximal frequency (F(max)), minimal frequency (F(min)) and final frequency (F(end))] were analysed. No male vocalized with 0 V; the number of animals that vocalized increased at 2 and 3 V and increased again at 4, 5 and 6 V (p < 0.05). The latency time from the beginning of each series (each voltage) decreased until 4 V (p < 0.01). The number of vocalizations/voltage increased from 4 V (p < 0.05). The length of each vocalization and the total time during which animals vocalized were greater in YM than AM (p = 0.02 and p = 0.01, respectively). Similarly, the fundamental frequencies were higher in YM than AM (p ≤ 0.05). Overall, we concluded that the vocalizations emitted during electroejaculation in pampas deer under general anaesthesia are related to the voltage applied during the process. Young males vocalize more time, probably due to a greater sensibility to the electric stimulation. The differences in the characteristics of the vocalizations between adult and young males may be related to the anatomic differences in the neck of adult or young males.

    Attempts to determine the influence of testicular hormones on learning and memory in males have yielded contradictory results. The present studies examined whether testicular hormones are important for maximal levels of spatial memory in young adult male rats. To minimize any effect of stress, we used the Object Location Task which is a spatial working memory task that does not involve food or water deprivation or aversive stimuli for motivation. In Experiment 1 sham gonadectomized male rats demonstrated robust spatial memory, but gonadectomized males showed diminished spatial memory. In Experiment 2 subcutaneous testosterone (T) capsules restored spatial memory performance in gonadectomized male rats, while rats with blank capsules demonstrated compromised spatial memory. In Experiment 3, gonadectomized male rats implanted with blank capsules again showed compromised spatial memory, while those with T, dihydrotestosterone (DHT), or estradiol (E) capsules demonstrated robust spatial memory, indicating that T's effects may be mediated by its conversion to E or to DHT. Gonadectomized male rats injected with Antide, a gonadotropin-releasing hormone receptor antagonist which lowers luteinizing hormone levels, also demonstrated spatial memory, comparable to that shown by T-, E-, or DHT-treated males. These data indicate that testicular androgens are important for maximal levels of spatial working memory in male rats, that testosterone may be converted to E and/or DHT to exert its effects, and that some of the effects of these steroid hormones may occur via negative feedback effects on LH.

    The present study aims to evaluate whether perinatal nicotine (NIC) exposure increases obesity susceptibility in adult male rat offspring by altering early adipogenesis. NIC was sc administered (2.0 mg/kg per day) to pregnant rats from gestational day 9 to the time of weaning (postnatal day 28). At weaning, NIC-exposed male pups had an increased body weight and inguinal sc fat mass and a decreased average cell area of adipocyte, which was accompanied by an overexpression of adipogenic and lipogenic genes in the epididymal white adipose tissue. Additionally, the hepatic lipogenic gene levels from NIC-exposed male pups were also affected. At 12 and 26 weeks of age, body weight and fat mass were increased, whereas there was no change in food intake in NIC-exposed male offspring. Adipogenic and lipogenic genes, glucose transporter 4, and leptin mRNA levels were increased, whereas adiponectin mRNA levels were decreased in the epididymal white adipose tissue of NIC-exposed males. The hepatic lipogenic gene expression of NIC-exposed males was increased. NIC-exposed male offspring showed normal glycemia and a higher serum insulin level, homeostasis model assessment of insulin resistance, and homeostasis model assessment of β-cell function. Furthermore, the NIC-exposed male offspring showed higher serum lipids and Castelli index I and lower nonesterified fatty acid. At 26 weeks, in the ip glucose and insulin tolerance tests, the glucose clearance was delayed, and the area under the curve was higher in the NIC-exposed male offspring. In conclusion, perinatal NIC exposure increased obesity susceptibility in adult male rat offspring by altering early adipogenesis.

    Background: To assess the effects of resistance training on circulating irisin concentration in older male adults, and to investigate the association between resistance training induced alteration of irisin and body fat. Methods: Seventeen older adults (mean age is 62.1 years old) were randomized into old control group (male, n = 7), and old training group (male, n = 10). The control group has no any exercise intervention. The resistance training group underwent leg muscle strength and core strength training program two times/wk, 55 min/class for 12 weeks. Before and after the intervention, we evaluated serum irisin level and body composition. Results: Serum irisin level was significantly increased in the resistance training group after the 12 weeks intervention period (P < 0.01), but not in the control group. In the resistance training group, the reduction in whole-body fat percent was negatively correlated with the increase in serum irisin level (r = −0.705, P < 0.05). Conclusion: After the 12 weeks intervention, circulating irisin levels were significantly elevated in the older adults. In summary, serum irisin may be involved in the regulation of body fat in older male adults. PMID:28382004

    2008-02-01

    Anabolic androgenic steroids (AAS) are synthetic derivatives of testosterone used by over half a million adolescents in the United States for their tissue-building potency and performance-enhancing effects. AAS also affect behavior, including reports of heightened aggression and changes in sexual libido. The expression of sexual and aggressive behaviors is a function of complex interactions among hormones, social context, and the brain, which is extensively remodeled during adolescence. Thus, AAS may have different consequences on behavior during adolescence and adulthood. Using a rodent model, these studies directly compared the effects of AAS on the expression of male sexual and aggressive behaviors in adolescents and adults. Male Syrian hamsters were injected daily for 14 days with either vehicle or an AAS cocktail containing testosterone cypionate (2 mg/kg), nandrolone decanoate (2 mg/kg), and boldenone undecylenate (1 mg/kg), either during adolescence (27-41 days of age) or in adulthood (63-77 days of age). The day after the last injection, males were tested for either sexual behavior with a receptive female or agonistic behavior with a male intruder. Adolescent males treated with AAS showed significant increases in sexual and aggressive behaviors relative to vehicle-treated adolescents. In contrast, AAS-treated adults showed significantly lower levels of sexual behavior compared with vehicle-treated adults and did not show heightened aggression. Thus, adolescents, but not adults, displayed significantly higher behavioral responses to AAS, suggesting that the still-developing adolescent brain is more vulnerable than the adult brain to the adverse consequences of AAS on the nervous system and behavior.

    BACKGROUND Praziquantel has been cited as the only drug for treating schistosomiasis. However, concerns over drug resistance have encouraged the search for novel drug leads. The antimalarial drug primaquine possesses interesting anti-schistosmal properties. OBJECTIVES This study is the first to document the potential role of primaquine as a schistosomicide and the ultrastructural changes induced by primaquine on juvenile or adult male worms of Schistosoma mansoni. METHODS Ultrastructural alterations in the tegumental surface of 21-day-old juvenile and adult male worms of S. mansoni were demonstrated following primaquine treatment at different concentrations (2, 5, 10, 15, and 20 µg/mL) and incubation periods (1, 3, 6, 24, and 48 h) in vitro, using both scanning and transmission electron microscopy. FINDINGS At low concentrations (2, 5, and 10 µg/mL) both juvenile and adult male worms were alive after 24 h of incubation, whereas contraction, paralysis, and death of all worms were observed after 24 h of drug exposure at 20 µg/mL. The tegument of juvenile and adult male worms treated with primaquine exhibited erosion, peeling, and sloughing. Furthermore, extensive damage of both tegumental and subtegumental layers included embedded spines, and shrinkage of muscles with vacuoles. The in vitro results confirmed that primaquine has dose-dependent effects with 20 µg/mL as the most effective concentration in a short incubation period. MAIN CONCLUSIONS The schistosomicidal activity of primaquine indicates that this drug possesses moderate in vitro activity against juvenile and adult male worms, since it caused high mortality and tegumental alterations. This study confirmed that the antimalarial drug primaquine possesses anti-schistosomal activity. Further investigation is needed to elucidate its mechanism of action. PMID:28327785

    Recent experiments have shown that sexual interactions prior to cell proliferation cause an increase in neurogenesis in adult male rats. Because adult neurogenesis is critical for some forms of memory, we hypothesized that sexually induced changes in neurogenesis may be involved in mate recognition. Sexually naive adult male rats were either exposed repeatedly to the same sexual partner (familiar group) or to a series of novel sexual partners (unfamiliar group), while control males never engaged in sexual interactions. Ovariectomized female rats were induced into estrus every four days. Males were given two injections of BrdU (200 mg/kg) to label proliferating cells, and the first sexual interactions occurred three days later. Males in the familiar and unfamiliar groups engaged in four, 30 min sexual interactions at four-day intervals, and brain tissue was collected the day after the last sexual interaction. Immunohisotchemistry followed by microscopy was used to quantify BrdU-labeled cells. Sexual interactions with unfamiliar females caused a significant reduction in neurogenesis in the dentate gyrus compared to males that interacted with familiar females and compared to the control group. The familiar group showed no difference in neurogenesis compared to the control group. There were no differences in the amount of sexual behavior (mounts, intromissions, ejaculations, or contact time) that the familiar and unfamiliar groups engaged in, indicating that the differences in neurogenesis were not due to the relative amounts of sexual activity. In a second experiment, we tested whether this effect was unique to sexual interactions by replicating the entire procedure using anestrus females. We found that interactions with unfamiliar anestrus females reduced neurogenesis relative to the other groups, but this effect was not statistically significant. In combination, these results indicate that interactions with unfamiliar females reduce adult neurogenesis and the effect

    A new adult diet formulation was evaluated for sterile Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart) males at the emergence and release facility of fruit flies in Mexico. The formulation consists of hydrolyzed protein, sugar, juvenile hormone analogue methoprene, and water. The proportion of the ingredients between the solute (4% hydrolyzed protein and 96% sugar) and solvent (10% methoprene and 90% water) was 5:1. This new formulation was called the 1:24 formulation. The main objectives of this study were to develop a simple way to supply the 1:24 formulation to adults and to compare the sexual performance of these flies with the performance of flies fed a standard diet (called the Mubarqui formulation) used at the emergence and release facility of fruit flies in Mexico. The preparation, time, and cost also were evaluated. The results showed no significant differences in the sexual behaviors of the males (number of males mating, number of males calling, mating latency, and mating duration) between the 1:24 formulation and the Mubarqui formulation. However, the cost and the required preparation time are much lower for the 1:24 formulation process than for the Mubarqui formulation process. Based on these results, we recommend the 1:24 formulation as an additional adult diet option in the handling of sterile flies. Its application is practical and does not require changes in packaging systems. The contribution of our findings and their potential application to the improvement of the sterile insect technique are discussed.

    Methamphetamine is one of the most common illicit drugs abused during pregnancy. The neurological effects of prenatal methamphetamine are well known. However, few studies have investigated the potential effects of prenatal methamphetamine on adult cardiovascular function. Previous work demonstrated that prenatal cocaine exposure increases sensitivity of the adult heart to ischemic injury. Methamphetamine and cocaine have different mechanisms of action, but both drugs exert their effects by increasing dopaminergic and adrenergic receptor stimulation. Thus the goal of this study was to determine whether prenatal methamphetamine also worsens ischemic injury in the adult heart. Pregnant rats were injected with methamphetamine (5 mg·kg(-1)·day(-1)) or saline throughout pregnancy. When pups reached 8 wk of age, their hearts were subjected to ischemia and reperfusion by means of a Langendorff isolated heart system. Prenatal methamphetamine had no significant effect on infarct size, preischemic contractile function, or postischemic recovery of contractile function in male hearts. However, methamphetamine-treated female hearts exhibited significantly larger infarcts and significantly elevated end-diastolic pressure during recovery from ischemia. Methamphetamine significantly reduced protein kinase Cε expression and Akt phosphorylation in female hearts but had no effect on these cardioprotective proteins in male hearts. These data indicate that prenatal methamphetamine differentially affects male and female sensitivity to myocardial ischemic injury and alters cardioprotective signaling proteins in the adult heart.

    Stroke is a high-frequency disorder placing a significant burden on the health care systems, being the foremost cause of complex chronic disability in adults. Devising systems that can enhance the prevention of stroke recurrence is an important priority and challenge in both the developed and the developing world. The potential for recurrent stroke can be substantially reduced by effective management of vascular risk factors. Telestroke is a tool with potential application to improve risk management of stroke survivors. Lack of acknowledgment of existing practices as well as lack of awareness of potential financial barriers to diffusion of telestroke can lead to limited implementation. Telestroke offers service providers the opportunity to access large numbers of stroke survivors targeting secondary prevention. The ideal 'telestroke model' provides service support, education for the patient and caregiver, as well as integration of specialist and primary care services. Effective use of technological advances, with adequate recognition of the importance of human interaction in the long-term management of a largely elderly population of stroke survivors is challenging but possible. Telestroke should be systems- and not technology-driven. Barriers in the implementation of telestroke have been identified as insufficient planning of IT infrastructure, lack of long-term vision for sustainability, a lack of contextual perspective as well as poor communication across domains. Future telestroke models should provide effective action in an integrated model of care recognizing and involving all existing players and practices.

    The current review explores the complex paths that can lead to adolescent and young adult males becoming sexually abusive. Because sexual abuse is an ongoing issue in our society that is often oversimplified, this article distinguishes between the various risk factors that predict sexually abusive behavior and types of sex offenders, particularly recidivistic offenders. It is imperative to focus on adolescents and young adults who sexually abuse because they represent a particularly important intervention point in preventing sexual abuse in comparison to older age groups and address the importance of differentiating among youths who sexually abuse, particularly between one-time offenders and recidivistic offenders. Implications for addressing these differences are discussed.

    Aripiprazole is an atypical antipsychotic that acts as a partial agonist at dopamine D2 receptors. Compared to other atypical antipsychotics, aripiprazole has less metabolic side effects and is less likely to increase prolactin. Moreover, it has been shown to have a unique prolactin lowering effect. While aripiprazole has been associated with subnormal prolactin levels in children, no documented cases of hypoprolactinemia in adults exist thus far. Here we report a case of aripiprazole-induced hypoprolactinemia in an adult male with first-episode psychosis, and the possible effects of abnormally low prolactin are discussed.

    PURPOSE Childhood cancer survivors (CCSs) are at increased risk for poor health-related quality of life (HRQOL) and chronic health conditions -- both of which can be exacerbated by unhealthy lifestyle behaviors. Developing a clearer understanding of the associations between HRQOL, lifestyle behaviors, and medical and demographic variables (e.g., age/developmental stage at time of diagnosis) is an important step toward developing more targeted behavioral interventions for this population. METHOD Cross-sectional questionnaires were completed by 170 CCSs who were diagnosed with leukemia, lymphoma, sarcoma, or a cancer of the central nervous system (CNS) and treated at a comprehensive cancer center between 1992 and 2007. Questionnaires addressed weight status, lifestyle behaviors, aspects of HRQOL, and intervention preferences. RESULTS Adolescent and young adult survivors (AYAs) and survivors of CNS tumors or lymphoma reported significantly (p<.05) poorer HRQOL across multiple domains compared to those diagnosed at an earlier age, survivors of leukemia or sarcoma, and healthy populations. A significant proportion also failed to meet national recommendations for dietary intakes (39–94%) and physical activity (65%). Female survivors reported poorer physical functioning and consumed less dietary fiber and fruits and vegetables than did male survivors. They also expressed the strongest interest in participating in diet and exercise interventions. CONCLUSION Findings support the premise that females, AYAs, and survivors of cancers of the CNS or lymphoma are “at risk” subgroups within the CCS population for poor dietary practices, sedentary behaviors, and poor HRQOL. Future research should focus on developing diet and PA interventions to improve HRQOL that target these groups. IMPLICATIONS FOR SURVIVORS Greater consideration of the role of gender, developmental stage, and the HRQOL challenges facing CCSs may help researchers to develop targeted behavioral interventions

    BACKGROUND: To determine the prevalence of metabolic syndrome in survivors of childhood leukemia in Isfahan, Iran. METHODS: During a 4-year period (2003 to 2007), 55 children (33 male and 22 female) diagnosed with ALL at Unit of Hematology/ Oncology, Department of Pediatrics, Isfahan University of Medical Science, were enrolled in this cross-sectional study. Metabolic syndrome was defined using the modified version of Adult Treatment Panel (ATP III) crite-ria. Insulin resistance was defined based on the homeostasis model assessment index (HOMA-IR). RESULTS: The mean age of participates was 10.4 years (range 6-19 years) and the mean interval since completion of chemotherapy was 35 months. Twenty percent (11/55) of survivors (10 male, 1 female) met criteria for diagnosis of metabolic syndrome. Obesity was observed in one forth of patients and nearly 3/4 of obese patients had metabolic syndrome. High serum insulin levels were found in 16% of participants and in 63% of obese survivors. The mean insulin levels in survivors with metabolic syndrome was three-times more than those without (28.3 mu/l vs. 9.57 mu/l, p = 0.004). Insulin resistance was detected in 72.7% of survivors with metabolic syndrome and it was positively correlated with serum triglycerides (0.543, p ≤ 0.001), systolic and diastolic BP (0.348, p = 0.01 and 0.368, p = 006 respectively), insulin levels (0.914, p < 0.001) and blood sugar (0.398, p = 003). CONCLUSIONS: The prevalence of metabolic syndrome in survivors of childhood leukemia in Iran is higher than developed countries. Nearly all of the obese patients had metabolic syndrome. Weight control and regular physical exercise are recommended to the survivors. PMID:21772869

    Treatment with Spinacia oleracea extract (SO; 400 mg/kg body weight) decreased the locomotor activity, grip strength, increased pentobarbitone induced sleeping time and also markedly altered pentylenetetrazole induced seizure status in Holtzman strain adult male albino rats. SO increased serotonin level and decreased both norepinephrine and dopamine levels in cerebral cortex, cerebellum, caudate nucleus, midbrain and pons and medulla. Result suggests that SO exerts its CNS depressive effect in PTZ induced seizure by modulating the monoamines in different brain areas.

    The biology and reproductive anatomy of male loggerhead sea turtles (Caretta caretta) have been difficult to study. The principle method for evaluation of the coelomic cavity in both adult and juvenile male sea turtles is celioscopy. The purpose of this study was to describe the technique and structures seen when scanning the inguinal region of live, wild-caught, adult male loggerhead sea turtles and to compare these findings to those resulting from celioscopy and necropsy. Twenty-one adult male loggerhead sea turtles were collected by trawling in the Cape Canaveral shipping channel in April 2007. All turtles were placed in dorsal recumbency and imaged with a Sonosite 180 Vet Plus (Sonosite, Inc., Bothell, Washington 98021, USA) and a microconvex, 4-7-MHz curvilinear array probe. The inguinal region was divided into four quadrants: cranial, lateral, medial, and caudal. Celioscopy was performed on 13 turtles, and biopsies were obtained of the testes and the epididymides to confirm correct identification of the structures. In the cranial aspect of the inguinal region, the urinary bladder and large and small intestines were identified. In the lateral inguinal region, the lung and kidney were seen. In the medial aspect of the inguinal region, the testis and epididymis were routinely identified. In the caudal aspect of the inguinal region, the coxofemoral joint was seen. A small learning curve was required; however, correlation with celioscopy and biopsy showed that consistent, repeatable identification of caudal coelomic structures was easily achieved. Ultrasound provided an inexpensive, rapid, noninvasive method to evaluate the reproductive anatomy of live-captured, male loggerhead sea turtles.

    The present study examines the effects of neonatal isolation on hippocampal LTP in adult male rats. Changes in dentate granule cell population measures, i.e., EPSP slope and population spike amplitude (PSA), evoked by tetanization of the medial perforant pathway were used to assess the effects of neonatal isolation on LTP over a period of 96 h. Following tetanization significant group differences were obtained for input/output (I/O) response measures of EPSP slope and PSA, with isolated males showing consistently higher values than in the other two groups. Comparisons made at 1 h post-tetanization (establishment of LTP) indicated that isolated males showed significantly greater enhancement than any other group. At 96 h (maintenance of LTP), however, neonatally isolated males showed significantly greater enhancement than either non-isolated siblings or unhandled controls. Additionally, isolation resulted in prolonging the duration of enhancement obtained from males. Thus, males show different enhancement profiles with respect to both the magnitude and duration of LTP and neonatal isolation alters these profiles in profound manner.

    Objectives: To compare muscle and bone health markers in adult males (aged 20-59 yrs) with and without muscular dystrophy (MD). Methods: Participants included 11 Fascioscapulohumeral (FSH), 11 Becker’s (Be), 9 limb girdle (LG), 11 Duchenne (DMD), and 14 non-dystrophic controls (CTRL). Physical activity was assessed using Bone (BPAQ) and disability specific (PASIPD) questionnaires. Bone QUS provided T- and Z scores from the Distal Radius (DR) and Mid-shaft tibia (MST). Tibialis anterior cross sectional area (TAACSA) was measured using B-mode ultrasound. Grip strength was measured in all but DMD. Results: Physical activity was lower in DMD, FSH and BeMD than CTRL (P<0.05), and lower in DMD than other MDs (P<0.01). T and Z scores were lower in DMD and Be than CTRL (DR, P<0.05); and lower in DMD than CTRL, LG, and FSH (MST, P<0.01). TAACSA and grip strength was 35-59% and 50-58% smaller in MD than CTRL, respectively (P<0.01). Within MD, BPAQ correlated with bone QUS measures (r=0.42-0.38, P<0.01). PASIPD correlated with grip strength (r=0.65, P<0.01) and TAACSA (r=0.46, P<0.01). Conclusion: Muscle size, strength, and bone health was lower in adult males with MD compared to adult males without MD, the extent of this is partially determined by physical activity. PMID:27973386

    Background & Aims Mounting evidence indicates that maternal exercise confers protection to adult offspring against various diseases. Here we hypothesized that maternal exercise during gestation would reduce high fat diet (HFD) induced hepatic steatosis in adult rat offspring. Methods Following conception, pregnant dams were divided into either voluntary wheel running exercise (GE) or wheel-locked sedentary (GS) groups throughout gestation (days 4-21). Post-weaning, offspring received either normal chow diet (ND; 10% fat, 70% carbohydrate, 20% protein) or high-fat diet (HFD; 45% fat, 35% carbohydrate, and 20% protein) until sacrifice at 4-or 8-months of age. Results GE did not affect offspring birth weight or litter size. HFD feeding in offspring increased weight gain, % body fat, and glucose tolerance test area under the curve (GTT-AUC). Male offspring from GE dams had reduced % body fat across all ages (p < 0.05). In addition, 8-mo male offspring from GE dams were protected against HFD-induced hepatic steatosis, which was associated with increased markers of hepatic mitochondrial biogenesis (PGC-1α and TFAM), autophagic potential (ATG12:ATG5 conjugation) and hepatic triacylglycerol secretion (MTTP). Conclusions The current study provides the first evidence that gestational exercise can reduce susceptibility to high fat diet induced hepatic steatosis in adult male offspring. PMID:26325536

    In this study, we performed an in-depth characterization of the male pediatric infant urinary proteome by parallel proteomic analysis of normal healthy adult (n =6) and infant (n =6) males and comparison to available published data. A total of 1584 protein groups were identified. Of these, 708 proteins were identified in samples from both cohorts. Although present in both cohorts, 136 of these common proteins were significantly enriched in urine from adults and 94 proteins were significantly enriched in urine from infants. Using Gene Ontology, we found that the infant-enriched or specific subproteome (743 proteins) had an overrepresentation of proteins that are involved in translation and transcription, cellular growth and metabolic processes. In contrast, the adult enriched or specific subproteome (364 proteins) showed an overexpression of proteins involved in immune response and cell adhesion. This study demonstrates that the non-diseased male urinary proteome is quantitatively affected by age, has age-specific subproteomes, and identifies a common subproteome with no age-dependent abundance variations. These findings highlight the importance of age-matching in urinary proteomics. PMID:23707565

    The aim of this study was to evaluate the effect of different doses of Malaysian honey on male reproductive parameters in adult rats. Thirty-two healthy adult male Sprague-Dawley rats were randomly divided into four groups (eight rats per group). Group 1 (control group) was given 0.5 ml of distilled water. Groups 2, 3 and 4 were given 0.2, 1.2 and 2.4 g kg(-1) body weight of honey respectively. The rats were treated orally by gavage once daily for 4 weeks. Honey did not significantly alter body and male reproductive organs weights. The rats in Group 3 which received honey at 1.2 g kg(-1) had significantly higher epididymal sperm count than those in Groups 1, 2 and 4. No significant differences were found for the percentage of abnormal sperm, elongated spermatid count, reproductive hormonal levels as well as the histology of the testis among the groups. In conclusion, Malaysian honey at a dose of 1.2 g kg(-1) daily significantly increased epididymal sperm count without affecting spermatid count and reproductive hormones. These findings might suggest that oral administration of honey at this dose for 4 weeks may enhance spermiogenesis in adult rats.

    Abstract World Health Organization recommends a target for the male circumcision prevalence rate of 80%. This rate will have a substantial impact on the human immunodeficiency virus-acquired immunodeficiency syndrome epidemic in Eastern and Southern Africa. The objective of the study was to assess whether an innovative intervention can lead to an increased voluntary male medical circumcision (VMMC) uptake among adults in a short time. This prospective observational study of a demand generation intervention was conducted in the township of Orange Farm (South Africa) in August to November 2015. In this community male circumcision prevalence rate among adults was stable between 2010 and 2015 at 55% and 57%, despite regular VMMC campaigns at community level and the presence of a VMMC clinic that offered free VMMC. The intervention took place in a random sample of 981 households where 522 men aged 18 to 49 years accepted to participate in the study. Among the 226 uncircumcised men, 212 accepted to be enrolled in the intervention study. A personal male circumcision adviser trained in interpersonal communication skills was assigned to each uncircumcised participant. The male circumcision advisers were trained to explain the risks and benefits of VMMC, and to discuss 24 possible reasons given by men for not being circumcised. Participants were then followed for 9 weeks. Each participant had a maximum of 3 motivational interviews at home. Participants who decided to be circumcised received financial compensation for their time equivalent to 2.5 days of work at the minimum South African salary rate. Among the 212 uncircumcised men enrolled in the intervention, 69.8% (148/212; 95% confidence interval [CI]; 63.4%–75.7%) agreed to be circumcised, which defines the uptake of the intervention. The male circumcision prevalence rate of the sample increased from 56.7% (296/522) to 81.4% (425/522; 77.9%–84.6%), P < 0.001, corresponding to a relative increase of 43.6% (95% CI

    2016-12-23

    This study examined measures of religion and spirituality in a sample of male and female emerging adult college students whose parents were either divorced or intact using the Personal Religious Inventory, the Duke University Religion Index, the Daily Spiritual Experiences Scale, the Spiritual Transcendence Scale, and the Spiritual Involvement and Beliefs Scale. Data were collected online, and 66% of participants received extra credit for participating. A main effect of sex was found, as females reported significantly higher scores than men on all but one measure of religion and spirituality, and the dataset was separated by sex. No differences were found between males from divorced and intact families. However, females from intact families scored significantly higher on all religion and spirituality measures than females from divorced families. This study suggests that females may respond differently than males to their parents' divorce in the context of religion and spirituality, and discusses possible reasons.

  11. Neonatal Maternal Separation Augments Carotid Body Response to Hypoxia in Adult Males but Not Female Rats

    Perinatal exposure to adverse experiences disrupts brain development, including the brainstem network that regulates breathing. At adulthood, rats previously subjected to stress (in the form of neonatal maternal separation; NMS) display features reported in patients suffering from sleep disordered breathing, including an increased hypoxic ventilatory response and hypertension. This effect is also sex-specific (males only). Based on these observations, we hypothesized that NMS augments the carotid body's O2-chemosensitivity. Using an isolated and perfused ex vivo carotid body preparation from adult rats we compared carotid sinus nerve (CSN) responses to hypoxia and hypercapnia in carotid bodies harvested from adult rats that either experienced control conditions (no experimental manipulation) or were subjected to NMS (3 h/day from postnatal days 3 to 12). In males, the CSN response to hypoxia measured in preparations from NMS males was 1.5 fold higher than controls. In control rats, the female's response was similar to that of males; however, the increase in CSN activity measured in NMS females was 3.0 times lower than controls. The CSN response to hypercapnia was not influenced by stress or sex. We conclude that NMS is sufficient to have persistent and sex-specific effects on the carotid body's response to hypoxia. Because NMS also has sex-specific effects on the neuroendocrine response to stress, we propose that carotid body function is influenced by stress hormones. This, in turn, leads to a predisposition toward cardio-respiratory disorders. PMID:27729873

    We investigated whether adolescent male rats show less habituation of corticosterone release than adult male rats to acute vs repeated (16) daily one hour episodes of isolation stress, as well as the role of partner familiarity during recovery on social behavior, plasma corticosterone, and Zif268 expression in brain regions. Adolescents spent more time in social contact than did adults during the initial days of the repeated stress procedures, but both adolescents and adults that returned to an unfamiliar peer after isolation had higher social activity than rats returned to a familiar peer (p=0.002) or undisturbed control rats (p<0.001). Both ages showed evidence of habituation, with reduced corticosterone response to repeated than acute isolation (p=0.01). Adolescents, however, showed sensitized corticosterone release to repeated compared with an acute pairing with an unfamiliar peer during recovery (p=0.03), a difference not found in adults. Consistent with habituation of corticosterone release, the repeated isolation groups had lower Zif268 immunoreactive cell counts in the paraventricular nucleus (p<0.001) and in the arcuate nucleus (p=0.002) than did the acute groups, and adolescents had higher Zif268 immunoreactive cell counts in the paraventricular nucleus than did adults during the recovery period (p<0.001), irrespective of stress history and partner familiarity. Partner familiarity had only modest effects on Zif268 immunoreactivity, and experimental effects on plasma testosterone concentrations were only in adults. The results highlight social and endocrine factors that may underlie the greater vulnerability of the adolescent period of development.

    This study evaluated the clinical features of 276 patients with aggressive adult T-cell leukaemia-lymphoma (ATL) in 3 Japan Clinical Oncology Group (JCOG) trials. We assessed the long-term survivors who survived >5 years and constructed a prognostic index (PI), named the JCOG-PI, based on covariates obtained by Cox regression analysis. The median survival time (MST) of the entire cohort was 11 months. In 37 patients who survived >5 years, no disease-related deaths in 10 patients with lymphoma-type were observed in contrast to the 10 ATL-related deaths in other types. In multivariate analysis of 193 patients, the JCOG-PI based on corrected calcium levels and performance status identified moderate and high risk groups with an MST of 14 and 8 months respectively (hazard ratio, 1·926). The JCOG-PI was reproducible in an external validation. Patients with lymphoma-type who survived >5 years might have been cured. The JCOG-PI is valuable for identifying patients with extremely poor prognosis and will be useful for the design of future trials combining new drugs or investigational treatment strategies.

    Research has consistently demonstrated a link between the experience of adverse childhood experiences (ACEs) and adult health conditions, including mental and physical health problems. While a focus on the prevention or mitigation of adversity in childhood is an important direction of many programs, many individuals do not access support services until adulthood, when health problems may be fairly engrained. It is not clear which interventions have the strongest evidence base to support the many adults who present to services with a history of ACEs. The current review examines the evidence base for psychosocial interventions for adults with a history of ACEs. The review focuses on interventions that may be provided in primary care, as that is the setting where most patients will first present and are most likely to receive treatment. A systematic review of the literature was completed using PsycInfo and PubMed databases, with 99 studies identified that met inclusion and exclusion criteria. These studies evaluated a range of interventions with varying levels of supportive evidence. Overall, cognitive-behavioral therapies (CBT) have the most evidence for improving health problems - in particular, improving mental health and reducing health-risk behaviors - in adults with a history of ACEs. Expressive writing and mindfulness-based therapies also show promise, whereas other treatments have less supportive evidence. Limitations of the current literature base are discussed and research directions for the field are provided.

    Commercial mixtures of chlorpyrifos and cypermethrin pesticides are widely used to enhance the toxic effects of cypermethrin on target insects. So, the purpose of the current study was to evaluate the individual and combined toxic effects of chlorpyrifos (CPF) and cypermethrin (CYP) on reproductive system of adult male albino rats. Forty adult male albino rats were randomized into main four groups: group I (control group) included 16 rats, subdivided into negative and positive control; group II (eight rats) received chlorpyrifos 6.75 mg/kg b.w./orally∕daily); group III (eight rats) (received cypermethrin 12.5 mg/kg b.w./orally∕daily); and group IV (eight rats) (received chlorpyrifos and cypermethrin at the same previously mentioned doses). All treatments were given by oral gavage for 12 weeks. We found that single CPF and CYP exposures significantly have adverse effects on reproductive function of adult male albino rats manifested by reduced testicular weight, decreased sperm count, motility and viability, significantly increased percent of morphologically abnormal spermatozoa, and significant increments in sperm DNA fragmentation index (DFI) with respect to control group. Furthermore, serum follicle stimulating hormone, luteinizing hormone, and testosterone levels were decreased significantly compared to control group. This was accompanied with histopathological changes in the testis of rats such as necrosis, degeneration, decreasing number of spermatogenic cells in some seminiferous tubules, edema, congested blood vessels, and exudate in interstitial tissue of the testis. Notably, all these changes were exaggerated in rats treated concomitantly with chlorpyrifos and cypermethrin rendering the mixture more toxic than the additive effects of each compound and causing greater damage on the reproductive system of male albino rats than the individual pesticides.

    Human exposure to lead is a substantial public health hazard worldwide and is particularly problematic in the Republic of South Africa given the country's late cessation of leaded petrol. Lead exposure is associated with a number of serious health issues and diseases including developmental and cognitive deficiency, hypertension and heart disease. Understanding the distribution of lifetime lead burden within a given population is critical for reducing exposure rates. Femoral bone from 101 deceased adult males living in urban Transvaal Province (now Gauteng Province), South Africa between 1960 and 1998 were analyzed for lead concentration by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Of the 72 black and 29 white individuals sampled, chronic lead exposure was apparent in nearly all individuals. White males showed significantly higher median bone lead concentration (ME = 10.04 µg·g(-1)), than black males (ME = 3.80 µg·g(-1)) despite higher socioeconomic status. Bone lead concentration covaries significantly, though weakly, with individual age. There was no significant temporal trend in bone lead concentration. These results indicate that long-term low to moderate lead exposure is the historical norm among South African males. Unexpectedly, this research indicates that white males in the sample population were more highly exposed to lead.

    Isobutyl-paraben (IBP), one of the most widely used preservatives, exhibits estrogenic activity. In this study, we analyzed the effects of maternal IBP treatment on the emotional behavior and learning performance in mature offspring. Pregnant female Sprague-Dawley rats were treated with IBP via a subcutaneous Silastic capsule. Consequently, the offspring were exposed to IBP during gestation through the placentae, and before weaning through the milk. Male and female offspring were tested for emotional behavior in an open field and in an elevated plus maze at five and six weeks old, respectively. IBP-exposed male (but not female) rats spent less time in the open arms of the elevated plus maze. At 11 weeks old, all females were gonadectomized and treated chronically with 17beta-estradiol or cholesterol by Silastic capsules; all males were kept intact. They were tested for learning performance in a passive avoidance test and a Morris water maze. IBP exposure impaired the performance of males in the passive avoidance test. These findings suggest that male rats are more affected by early exposure to IBP than female rats. IBP affects their adult behavior including anxiety and learning abilities.

    Studying the neural correlates of smoking behaviors in young adulthood is of great importance to improve treatment outcomes. In previous addiction studies, the important roles of the salience network (SN) in drug cue processing and cognitive control have been revealed. Unfortunately, few studies focused on the resting-state functional connectivity and structural integrity abnormalities of SN in young adult smokers, and less is known about its association with smoking behaviors and cognitive control deficits. Thirty-one young male adult smokers and 30 age-, education- and gender-matched nonsmokers participated in this study. The structural and functional connectivity differences of SN were investigated between young adult smokers and nonsmokers by using diffusion tensor imaging (DTI) and resting-state functional connectivity (RSFC), which were then correlated with the smoking behavioral assessments (pack-years and Fagerström Test for Nicotine Dependence (FTND)) as well as impaired cognitive control measured by the Stroop task. Within SN, reduced RSFC and increased fractional anisotropy (FA) were found between the anterior cingulate cortex (ACC) and the right insula in young adult smokers relative to nonsmokers. The RSFC between the ACC and right insula was negatively correlated with the number of errors during the incongruent condition of the Stroop task in young adult smokers. Additionally, the right insula-ACC RSFC was negatively correlated with pack-years in young adult smokers. Our results revealed abnormal RSFC and structural integrity within the SN in young adult smokers, which shed new insights into the neural mechanism of nicotine dependence.

    We tested the hypothesis that neonatal exposure to hypoxia alters acclimatization to chronic hypoxia later in life. Rat pups were exposed to normobaric hypoxia (12% O(2); nHx group) in a sealed chamber, or to normoxia (21% O(2); nNx group) from the day before birth to postnatal day 10. The animals were then raised in normal conditions until reaching 12 wk of age. At this age, we assessed ventilatory and hematological acclimatization to chronic hypoxia by exposing male and female nHx and nNx rats for 2 wk to 10% O(2). Minute ventilation, metabolic rate, hypoxic ventilatory response, hematocrit, and hemoglobin levels were measured both before and after acclimatization. We also quantified right ventricular hypertrophy as an index of pulmonary hypertension both before and after acclimatization. There was a significant effect of neonatal hypoxia that decreases ventilatory response (relative to metabolic rate, VE/VCO(2)) to acute hypoxia before acclimatization in males but not in females. nHx rats had an impaired acclimatization to chronic hypoxia characterized by altered respiratory pattern and elevated hematocrit and hemoglobin levels after acclimatization, in both males and females. Right ventricular hypertrophy was present before and after acclimatization in nHx rats, indicating that neonatal hypoxia results in pulmonary hypertension in adults. We conclude that neonatal hypoxia impairs acclimatization to chronic hypoxia in adults and may be a factor contributing to the establishment of chronic mountain sickness in humans living at high altitude.

  2. Demographic response of black bears at Cold Lake, Alberta, to the removal of adult males

    Previous reports described an increase in population density following the removal of 23 adult male black bears (Ursus americanus) from a 218-km2 study area near Cold Lake, Alberta (the CLSA). This finding plays a central role in continuing debates over population regulation in bears, but has recently been criticized because density estimates were based on assumptions that were not met. Moreover, subsequent discussion has been predicated on conjecture that human exploitation had minimal influence on population dynamics. Our reanalysis supports previous descriptions of trends in bear density at Cold Lake. However, survival records revealed heavier exploitation than previously suspected. An underlying assumption of previous interpretationsCthat the Cold Lake bear population was naturally regulated near carrying capacityCno longer seems reasonable. Adult males deterred bears in other sex-age groups from using the CLSA; however, we found no evidence that birth or death rates were affected. The observed increase in local density should not be construed as a density-dependent response. Abrupt changes in local density might not have occurred if males had been removed from a larger area encompassing the CLSA.

    Whether environmental exposure to bisphenol A (BPA) may induce reproductive disorders is still controversial but certain studies have reported that BPA may cause meiotic abnormalities in C. elegans and female mice. However, little is known about the effect of BPA on meiosis in adult males. To determine whether BPA exposure at an environmentally relevant dose could induce meiotic abnormalities in adult male rats, we exposed 9-week-old male Wistar rats to BPA by gavage at 20 μg/kg body weight (bw)/day for 60 consecutive days. We found that BPA significantly increased the proportion of stage VII seminiferous epithelium and decreased the proportion of stage VIII. Consequently, spermiation was inhibited and spermatogenesis was disrupted. Further investigation revealed that BPA exposure delayed meiosis initiation in the early meiotic stage and induced the accumulation of chromosomal abnormalities and meiotic DNA double-strand breaks (DSBs) in the late meiotic stage. The latter event subsequently activated the phosphatidylinositol 3-kinase-related protein kinase (ATM). Our results suggest that long-term exposure to BPA may lead to continuous meiotic abnormalities and ultimately put mammalian reproductive health at risk.

    The renin-angiotensin-aldosterone system (RAAS) appears to contribute significantly to osmoregulation of fasting northern elephant seal (Mirounga angustirostris) pups; however, RAAS has not been characterized in fasting adult seals. Therefore, this study examined the contribution of RAAS to water turnover rates in fasting adult male northern elephant seals. Blood samples were obtained twice during their breeding fast at an interval of 6.5 wk, and water efflux rate was estimated by isotopic dilution during the same period. Serum electrolytes (Na+, K+, Cl-) and osmolality were unaltered between the two sampling periods, indicating ionic and osmotic homeostasis during the fast. Despite the lack of an increase in vasopressin, serum angiotensin II and aldosterone were increased and were significantly and positively correlated. Changes in aldosterone concentration and water efflux rate were significantly and negatively correlated, suggesting that the greater the increase in aldosterone, the smaller the loss of water. Adult male seals maintain ionic and osmotic homeostasis similar to that of fasting weaned pups, and this homeostasis appears to be mediated, at least in part, by RAAS, which probably contributes to increased water retention as well. The hormonal mechanisms by which northern elephant seals maintain water and electrolyte balance during fasting conditions appear to be similar regardless of age.

    Purpose: To develop a computed tomography (CT) organ dose estimation method designed to readily provide organ doses in a reference adult male and female for different scan ranges to investigate the degree to which existing commercial programs can reasonably match organ doses defined in these more anatomically realistic adult hybrid phantomsMethods: The x-ray fan beam in the SOMATOM Sensation 16 multidetector CT scanner was simulated within the Monte Carlo radiation transport code MCNPX2.6. The simulated CT scanner model was validated through comparison with experimentally measured lateral free-in-air dose profiles and computed tomography dose index (CTDI) values. The reference adult male and female hybrid phantoms were coupled with the established CT scanner model following arm removal to simulate clinical head and other body region scans. A set of organ dose matrices were calculated for a series of consecutive axial scans ranging from the top of the head to the bottom of the phantoms with a beam thickness of 10 mm and the tube potentials of 80, 100, and 120 kVp. The organ doses for head, chest, and abdomen/pelvis examinations were calculated based on the organ dose matrices and compared to those obtained from two commercial programs, CT-EXPO and CTDOSIMETRY. Organ dose calculations were repeated for an adult stylized phantom by using the same simulation method used for the adult hybrid phantom. Results: Comparisons of both lateral free-in-air dose profiles and CTDI values through experimental measurement with the Monte Carlo simulations showed good agreement to within 9%. Organ doses for head, chest, and abdomen/pelvis scans reported in the commercial programs exceeded those from the Monte Carlo calculations in both the hybrid and stylized phantoms in this study, sometimes by orders of magnitude. Conclusions: The organ dose estimation method and dose matrices established in this study readily provides organ doses for a reference adult male and female for different

    Key points Aerobic exercise, such as running, enhances adult hippocampal neurogenesis (AHN) in rodents.Little is known about the effects of high‐intensity interval training (HIT) or of purely anaerobic resistance training on AHN.Here, compared with a sedentary lifestyle, we report a very modest effect of HIT and no effect of resistance training on AHN in adult male rats.We found the most AHN in rats that were selectively bred for an innately high response to aerobic exercise that also run voluntarily and increase maximal running capacity.Our results confirm that sustained aerobic exercise is key in improving AHN. Abstract Aerobic exercise, such as running, has positive effects on brain structure and function, such as adult hippocampal neurogenesis (AHN) and learning. Whether high‐intensity interval training (HIT), referring to alternating short bouts of very intense anaerobic exercise with recovery periods, or anaerobic resistance training (RT) has similar effects on AHN is unclear. In addition, individual genetic variation in the overall response to physical exercise is likely to play a part in the effects of exercise on AHN but is less well studied. Recently, we developed polygenic rat models that gain differentially for running capacity in response to aerobic treadmill training. Here, we subjected these low‐response trainer (LRT) and high‐response trainer (HRT) adult male rats to various forms of physical exercise for 6–8 weeks and examined the effects on AHN. Compared with sedentary animals, the highest number of doublecortin‐positive hippocampal cells was observed in HRT rats that ran voluntarily on a running wheel, whereas HIT on the treadmill had a smaller, statistically non‐significant effect on AHN. Adult hippocampal neurogenesis was elevated in both LRT and HRT rats that underwent endurance training on a treadmill compared with those that performed RT by climbing a vertical ladder with weights, despite their significant gain in strength

    Rind and Welter (2014) examined first postpubertal coitus using the Kinsey sample, finding that reactions were just as positive, and no more negative, among minors with adults compared to minors with peers and adults with adults. In the present study, we examined first postpubertal male same-sex sexual experiences in the Kinsey same-sex sample (i.e., participants mostly with extensive postpubertal same-sex behavior), comparing reactions across the same age categories. These data were collected between 1938 and 1961 (M year: 1946). Minors under age 18 years with adults (M ages: 14.0 and 30.5, respectively) reacted positively (i.e., enjoyed the experience "much") often (70 %) and emotionally negatively (e.g., fear, disgust, shame, regret) infrequently (16 %). These rates were the same as adults with adults (M ages: 21.2 and 25.9, respectively): 68 and 16 %, respectively. Minors with peers (M ages: 13.3 and 13.8, respectively) reacted positively significantly more often (82 %) and negatively nominally less often (9 %). Minors with adults reacted positively to intercourse (oral, anal) just as often (69 %) as to outercourse (body contact, masturbation, femoral) (72 %) and reacted emotionally negatively significantly less often (9 vs. 25 %, respectively). For younger minors (≤14) with adults aged 5-19 years older, reactions were just as positive (83 %) as for minors with peers within 1 year of age (84 %) and no more emotionally negative (11 vs. 7 %, respectively). Results are discussed in relation to findings regarding first coitus in the Kinsey sample and to the cultural context particular to Kinsey's time.

    This study evaluated the effectiveness of group psychotherapy in reducing levels of shame and guilt in adult survivors of childhood sexual abuse at risk for HIV, and whether such reductions would mediate the effects of treatment on posttraumatic stress disorder (PTSD) symptoms. One hundred sixty-six women were randomized into 3 conditions: a trauma-focused group, a present-focused group, and a waitlist group. Women received 6 months of treatment and were assessed at pretreatment (T1), immediately posttreatment (T2), and 6 months posttreatment (T3). Both treatment conditions resulted in reduced shame and guilt. The treatment effect on PTSD symptoms was mediated by changes in shame, but it was not associated with changes in guilt. These findings suggest that, when treating childhood sexual abuse survivors' PTSD, it is important to address the negative self-appraisals, such as shame, that commonly accompany such symptoms.

    The large body size and high rates of metabolic heat production associated with male mating success in polygynous systems creates potential thermoregulatory challenges for species breeding in warm climates. This is especially true for marine predators carrying large blubber reserves intended for thermoregulation in cold water and fuel provision during extended fasts. Thermographic images were used to measure changes in skin temperature (T(S)) in adult male northern elephant seals (Mirounga angustirostris) over the breeding season. Environmental variables, primarily ambient temperature and solar radiation, were the principal determinants of mean and maximum T(S). When controlled for environmental variables, dominance rank significantly impacted mean T(S), being highest in alpha males. Behavioral activity significantly influenced T(S) but in a counter-intuitive way, with inactive males exhibiting the highest T(S). This was likely due to strong impacts of environmental variables on the kinds of behavior exhibited, with males being less active on warm, humid days at peak solar radiation. We classified thermal windows as areas in which T(S) was one standard deviation greater than mean T(S) for the individual seal within a thermograph. Thermal features suggest active physiological thermoregulation during and after combat and significant circulatory adaptations for heat dumping, as evidenced by recurring locations of thermal windows representing widely varying T(S) values. Frequent observations of localized T(S) above 37°C, particularly after combat, suggest the production of thermoregulatory stress during breeding behavior. Our findings demonstrate the importance of environmental drivers in shaping activity patterns during breeding and provide evidence for thermoregulatory costs of successful breeding in large polygynous males.

  10. Whole adult organism transcriptional profiling of acute metal exposures in male Zebrafish

    2014-01-01

    Background A convergence of technological breakthroughs in the past decade has facilitated the development of rapid screening tools for biomarkers of toxicant exposure and effect. Platforms using the whole adult organism to evaluate the genome-wide response to toxicants are especially attractive. Recent work demonstrates the feasibility of this approach in vertebrates using the experimentally robust zebrafish model. In the present study, we evaluated gene expression changes in whole adult male zebrafish following an acute 24 hr high dose exposure to three metals with known human health risks. Male adult zebrafish were exposed to nickel chloride, cobalt chloride or sodium dichromate concentrations corresponding to their respective 96 hr LC20, LC40 and LC60. Histopathology was performed on a subset of metal-exposed zebrafish to phenotypically anchor transcriptional changes associated with each metal. Results Comparative analysis identified subsets of differentially expressed transcripts both overlapping and unique to each metal. Application of gene ontology (GO) and transcription factor (TF) enrichment algorithms revealed a number of key biological processes perturbed by metal poisonings and the master transcriptional regulators mediating gene expression changes. Metal poisoning differentially activated biological processes associated with ribosome biogenesis, proteosomal degradation, and p53 signaling cascades, while repressing oxygen-generating pathways associated with amino acid and lipid metabolism. Despite appreciable effects on gene regulation, nickel poisoning did not induce any morphological alterations in male zebrafish organs and tissues. Histopathological effects of cobalt remained confined to the olfactory system, while chromium targeted the gills, pharynx, and intestinal mucosa. A number of enriched transcription factors mediated the observed gene response to metal poisoning, including known targets such as p53, HIF1α, and the myc oncogene, and novel

    Perfluorooctane sulfonate (PFOS) is a neurotoxic agent and it can disrupt the endocrine system activity. This work was undertaken to evaluate the possible effects of PFOS exposure on the hypothalamic-pituitary-testicular axis (HPT) in adult male rats, and to evaluate the possible morphological alterations induced by PFOS in the endocrine tissues of this axis. Adult male rats were orally treated with 0.5; 1.0; 3.0 and 6.0 mg of PFOS/kg/day for 28 days. After PFOS exposure, hypothalamic noradrenaline concentration increased in the anterior hypothalamus and in the median eminence, not changing in the mediobasal hypothalamus. PFOS treated rats presented a decrease of the gonadotropin releasing hormone (GnRH) gene expression, increasing the mRNA levels of the luteinizing hormone (LH) in rats treated with all doses administered except with the dose of 6 mg/kg/day. PFOS also induced a raise of the follicle stimulating hormone (FSH) gene expression in the animals exposed to 0.5 and 1.0 mg of PFOS/kg/day. After PFOS exposure, hypothalamic GnRH concentration was modified, LH and testosterone release was inhibited and FSH secretion was stimulated. Moreover, PFOS induced several histopathological alterations in the hypothalamus, pituitary gland and testis. The results obtained in the present study suggest in general terms that PFOS can inhibit the physiological activity of the reproductive axis in adult male rats, which could be explained, at least in part, by the structural alterations showed in the animals exposed to this chemical: very dense chromatin, condensed ribosomes and a loss of the morphology in the hypothalamus; a degeneration of the gonadotrophic cells, as well as a loss and degeneration of the spermatozoids and a very marked edema in the testis.

    Early exposure to psychostimulants has been found to lead to long-lasting effects on cognitive processes. Our lab has previously reported that juvenile male rats administered methamphetamine showed improved performance in a spatial navigation task when tested in adulthood (McFadden and Matuszewich, 2007). What is not known, however, is if these effects are specific to the developing rat, or if a similar methamphetamine protocol given to adult rats would lead to an equally beneficial long-term change in spatial cognition. In the current study, male rats were given 1 daily injection of 2mg/kg methamphetamine or saline for 15 days during either preadolescence (PD20-34) or adulthood (PD70-84). Approximately 45 days after treatment, all rats then underwent 5 days of place training in the Morris water maze at a time when juvenile rats reached adulthood. Similar to previous findings, juvenile rats exposed to repeated methamphetamine displayed shorter latencies and distances to reach the platform throughout training compared to saline-treated rats. The juvenile rats treated with methamphetamine also swam shorter distances and had faster latencies to the hidden platform compared to adult methamphetamine-treated rats. There were no significant differences in rats treated in adulthood with methamphetamine compared to saline-treated rats. Likewise, there were no effects of prior methamphetamine treatment or age on matching-to-place trials or visible platform trials. Overall, the results show that repeated methamphetamine exposure can selectively improve spatial learning in adult male rats when administered during preadolescence, but does not significantly affect spatial learning when administered in adulthood. Furthermore, the current findings demonstrate the unique susceptibility of the developing brain to drugs that modulate dopaminergic activity, as well as the long-term behavioral impact of exposure at critical ages.

  13. Impairment of male reproduction in adult rats exposed to hydroxyprogesterone caproate in utero

    Hydroxyprogesterone caproate is one of the most effective and widely used drugs for the treatment of uterine bleeding and threatened miscarriage in women. Hydroxyprogesterone caproate was administered to pregnant rats in order to assess the effect of intraperitoneal exposure to supranormal levels of hydroxyprogesterone caproate on the male reproductive potential in the first generation. The cauda epididymal sperm count and motility decreased significantly in rats exposed to hydroxyprogesterone caproate during embryonic development, when compared with control rats. The levels of serum testosterone decreased with an increase in follicle stimulating hormone and luteinizing hormone in adult rats exposed to hydroxyprogesterone caproate during the embryonic stage. It was suggested that the impairment of male reproductive performance could be mediated through the inhibition of testosterone production.

    Previous studies have found a clear relationship between prolactin (prl) and paternal care in various vertebrate taxa. In New World monkeys, it has been demonstrated in several species that fathers have high prolactin levels even during periods without infant rearing. In this study, we followed the reproductive careers of common marmoset males as they transitioned from being an adult son within their native family to fathering their own offspring for the first time. Specifically, we examined the first experience of elevated prolactin levels in marmoset males. Additionally, we investigated the effects of the total number of experienced births as well as of age on prolactin levels. Our results show that common marmoset males did not experience an increase in prolactin secretion after pairing or shortly before birth of their first infants. However, prolactin levels rose more than twofold after the birth of their first infants and had lowered again 2.5 months after this event. We found no correlation between prolactin levels and the number of previous births experienced or age. Our study demonstrates that further work about a possible enhancing effect of prolactin on paternal care, by means of experimentally reducing hormonal levels, should be conducted in common marmosets using first-time fathers before males experience the first paternal increase in prolactin levels.

    This study investigates how cancer survivors construct their identities and the impact on their psychological health, as measured by depression and survivor self-efficacy. Fourteen young adult survivors of pediatric cancer participated in a customized social networking and video blog intervention program, the LIFECommunity, over a 6-month period. Survivors were asked to share their stories on various topics by posting video messages. Those video blog postings, along with survey data collected from participants, were analyzed to see how cancer survivors expressed their identities, and how these identities are associated with survivors' psychosocial outcomes. In survivors who held negative stereotypes about cancer survivors, there was a positive relationship with depression while positive stereotypes had a marginal association with cancer survivor efficacy. Findings indicate that although pediatric cancer survivors often do not publicly discuss a "cancer survivor identity," they do internalize both positive and negative stereotypes about cancer survivorship. It is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.

    BACKGROUND Immune deficient male mice bearing human prostate cancer xenografts are used to evaluate therapeutic response to novel androgen ablation approaches and the results compared to surgical castration based upon assumption that testosterone microenvironment in intact and castrated adult male mice mimics eugonadal and castrated aging adult human males. METHODS To test these assumptions, serum total testosterone (TT) and free testosterone (FT) were determined longitudinally in groups (n > 20) of intact versus castrated adult male nude, NOG, and immune competent C57BL/6 mice. RESULTS In adult male mice, TT and FT varies by 30- to 100-fold within the same animal providing a microenvironment that is only equivalent to hypogonadal, not eugonadal, adult human males (TT is 1.7 ± 1.2 ng/ml [5.8 ± 4.1 nM] in nude and 2.5 ± 1.3 ng/ml [8.7 ± 4.4 nM] in NOG mice versus >4.2 ng/ml [14.7 nM] in eugonadal humans). This was confirmed based upon enhanced growth of androgen dependent human prostate cancer xenografts inoculated into mice supplemented with exogenous testosterone to elevate and chronically maintain serum TT at a level (5 ng/ml [18 nM]) equivalent to a 50-year-old eugonadal human male. In castrated mice, TT and FT range from 2 to 20 pg/ml (7–70 pM) and <0.8 pg/ml (<2.6 pM), respectively, which is equivalent to castrate resistant prostate cancer (CRPC) patients treated with abiraterone. This was confirmed based upon the inability of another CYP17A1 inhibitor, ketoconazole, to inhibit the growth of CRPC xenografts in castrated mice. CONCLUSIONS Adult male mice supplemented with testosterone mimic eugonadal human males, while unsupplemented animals mimic standard androgen ablation and castrated animals mimic abiraterone treated patients. These studies confirm what is claimed in Robert Burns’ poem “To a Mouse” that “The best laid schemes of mice and men/often go awry. PMID:23775398

    Mediastinal germ cell tumors are extragonadal germ cell tumors (EGGCTs) commonly seen in children and young adults. They are more common in men. Clinically they are classified as teratomas, seminomas, and nonseminomatous germ cell tumors. Primary mediastinal yolk sac neoplasm is an extremely rare tumor. We present here a very rare case of primary yolk sac tumor of the anterior mediastinum in a 73-year-old male. Mediastinal germ cell tumors have a worse prognosis than gonadal germ cell tumors. Chemotherapy followed by adjuvant surgery improves overall response in EGGCTs. However, comorbidities can render treatment with chemotherapy and surgery challenging in elderly patients.

    X-linked agammaglobulinemia (XLA) is caused by mutation in the gene coding for Bruton’s tyrosine kinase (BTK), which impairs peripheral B cell maturation and hypogammaglobulinemia. In this report, we present a case of XLA in a 22-year-old adult male. Genetic testing revealed a novel mutation located at the conserved region (c.383T>C). The patient had a history of recurrent respiratory tract infection which eventually progressed to chronic type II respiratory failure. Several pathogenic bacteria were isolated on culture of respiratory secretions obtained on bronchoscopy. The patient improved on treatment with antibiotics. PMID:27867589

    The nuclear receptor steroidogenic factor 1 (SF-1, AD4BP, NR5A1) is a key regulator of the endocrine axes and is essential for adrenal and gonad development. Partial rescue of Nr5a1−/− mice with an SF-1-expressing transgene caused a hypomorphic phenotype that revealed its roles in Leydig cell development. In contrast to controls, all male rescue mice (Nr5a1−/−;tg+/0) showed varying signs of androgen deficiency, including spermatogenic arrest, cryptorchidism, and poor virilization. Expression of various Leydig cell markers measured by immunohistochemistry, Western blot analysis, and RT-PCR indicated fetal and adult Leydig cell development were differentially impaired. Whereas fetal Leydig cell development was delayed in Nr5a1−/−;tg+/0 embryos, it recovered to control levels by birth. In contrast, Sult1e1, Vcam1, and Hsd3b6 transcript levels in adult rescue testes indicated complete blockage in adult Leydig cell development. In addition, between Postnatal Days 8 and 12, peritubular cells expressing PTCH1, SF-1, and CYP11A1 were observed in control testes but not in rescue testes, indicating SF-1 is needed for either survival or differentiation of adult Leydig cell progenitors. Cultured prepubertal rat peritubular cells also expressed SF-1 and PTCH1, but Cyp11a1 was expressed only after treatment with cAMP and retinoic acid. Together, data show SF-1 is needed for proper development of fetal and adult Leydig cells but with distinct primary functions; in fetal Leydig cells, it regulates differentiation, whereas in adult Leydig cells it regulates progenitor cell formation and/or survival.

    Adolescents are at greatest risk for traumatic brain injury (TBI) and repeat TBI (RTBI). TBI-induced hypopituitarism has been documented in both adults and juveniles and despite the necessity of pituitary function for normal physical and brain development, it is still unrecognized and untreated in adolescents following TBI. TBI induced hormonal dysfunction during a critical developmental window has the potential to cause long-term cognitive and behavioral deficits and the topic currently remains unaddressed. The purpose of this study was to determine if four mild TBIs delivered to adolescent male rats disrupts testosterone production and adult behavioral outcomes. Plasma testosterone was quantified from 72 hrs preinjury to 3 months postinjury and pubertal onset, reproductive organ growth, erectile function and reproductive behaviors were assessed at 1 and 2 months postinjury. RTBI resulted in both acute and chronic decreases in testosterone production and delayed onset of puberty. Significant deficits were observed in reproductive organ growth, erectile function and reproductive behaviors in adult rats at both 1 and 2 months postinjury. These data suggest adolescent RTBI-induced hypopituitarism underlies abnormal behavioral changes observed during adulthood. The impact of undiagnosed hypopituitarism following RTBI in adolescence has significance not only for growth and puberty, but also for brain development and neurobehavioral function as adults.

    Tobacco use is prevalent in the adolescent population. It is a major concern because tobacco is highly addictive and has also been linked to illicit drug use. There is not much research, however, on the interaction between nicotine and other stimulant drugs in animal models of early adolescence. This study examined the effects of chronic nicotine alone and on cocaine-stimulated activity in male and female periadolescent rats compared to male and female adult rats. During the seven-day nicotine pretreatment period, nicotine increased locomotor activity in all groups compared to vehicle controls. Male and female adult rats and female periadolescent rats developed sensitization to the locomotor-activating effects of nicotine over the 7-day treatment period, while male periadolescent rats did not. All groups treated with nicotine, however, exhibited sensitization to nicotine-induced repetitive motion over the 7-day nicotine treatment period. On day 8, male periadolescent rats pretreated with nicotine were more markedly sensitized to the locomotor-activating effects of cocaine than male adult rats, while female rats pretreated with nicotine were not sensitized to cocaine. In contrast, male and female periadolescent rats, but not adult rats, had increased amounts of repetitive beam breaks induced by cocaine after nicotine pretreatment. Overall, it appears that cross-sensitization to cocaine is greater in periadolescent than in adult rats, and that males are more sensitized than females. Thus, it may be that nicotine use during adolescence carries a greater risk than during adulthood and that male adolescents may be particularly vulnerable to the risk of cocaine abuse after nicotine use. This information should be taken into account so as to help us better understand the development of drug addiction in adolescents compared to adults.

  5. Temporal dynamics of attentional selection in adult male carriers of the fragile X premutation allele and adult controls

    Carriers of the fragile X premutation allele (fXPCs) have an expanded CGG trinucleotide repeat size within the FMR1 gene and are at increased risk of developing fragile x-associated tremor/ataxia syndrome (FXTAS). Previous research has shown that male fXPCs with FXTAS exhibit cognitive decline, predominantly in executive functions such as inhibitory control and working memory. Recent evidence suggests fXPCs may also exhibit impairments in processing temporal information. The attentional blink (AB) task is often used to examine the dynamics of attentional selection, but disagreements exist as to whether the AB is due to excessive or insufficient attentional control. In this study, we used a variant of the AB task and neuropsychological testing to explore the dynamics of attentional selection, relate AB performance to attentional control, and determine whether fXPCs exhibited temporal and/or attentional control impairments. Participants were adult male fXPCs, aged 18–48 years and asymptomatic for FXTAS (n = 19) and age-matched male controls (n = 20). We found that fXPCs did not differ from controls in the AB task, indicating that the temporal dynamics of attentional selection were intact. However, they were impaired in the letter-number sequencing task, a test of executive working memory. In the combined fXPC and control group, letter-number sequencing performance correlated positively with AB magnitude. This finding supports models that posit the AB is due to excess attentional control. In our two-pronged analysis approach, in control participants we replicated a previously observed effect and demonstrated that it persists under more stringent theoretical constraints, and we enhance our understanding of fXPCs by demonstrating that at least some aspects of temporal processing may be spared.

    We previously reported that neonatal isolation stress significantly changes measures of hippocampal long-term potentiation (LTP) in male and female juvenile rats, i.e., at 30 days of age. The changes in dentate granule population measures, i.e., excitatory postsynaptic potential (EPSP) and population spike amplitude (PSA), evoked by tetanization of the medial perforant pathway, indicated that juvenile rats exposed to neonatal isolation exhibit different enhancement profiles with respect to both the magnitude and duration of LTP in a sex-specific manner. Isolated males showed a significantly greater enhancement of LTP, while female "isolates" showed significantly longer LTP duration when compared to all other groups. The present study was designed to determine whether the effects of the neonatal isolation stress paradigm endures into adulthood. Rats isolated from their mothers for 1 h per day during postnatal days 2-9 were surgically prepared at 70-90 days of age, with stimulating and recording electrodes placed in the medial perforant pathway and the hippocampal dentate gyrus, respectively. Prior to tetanization, no significant effect of sex or treatment was obtained for baseline measures of EPSP slope or PSA. In order to rule out baseline differences in hippocampal cell excitability in female adult rats, we measured the response of dentate granule cells for one estrus cycle and found no pretetanization enhancement in the evoked response in either controls or previously stressed rats. Following tetanization, there was a significant treatment and sex effect. During the induction of LTP, PSA values were significantly enhanced in both isolated males and females and had significantly longer LTP duration when compared to the unhandled control group. Additionally, we observed that females took longer to reach baseline levels than males. Taken together, these results indicate that repeated infant isolation stress enhances LTP induction and duration in both males and

    There is evidence that Hispanic men are a high risk group for treatment delay for both heart attack and stroke. More targeted research is needed to elucidate this specific population's knowledge of warning signs for these acute events. This study sought to describe within-group disparities in Hispanic men's knowledge of heart attack and stroke symptomology. Multivariate techniques were used to analyze a multi-year Behavioral Risk Factor Surveillance Heart and Stroke module database. The data were cross-sectional and focused on health risk factors and behaviors. The research participants were U.S. male Hispanic adults aged 18-99. The main outcome measure for the study was heart attack and stroke symptom knowledge score. Multivariate logistic regression analysis yielded that Hispanic men aged >or=18 years who earned low scores on the composite heart attack and stroke knowledge questions (range 0-8 points) were more likely to: have less than a high school education, have deferred medical care because of cost, not have an identified health care provider, and be uninsured. There were significant within-group differences. Targeting educational efforts toward older (>or=55 years) Hispanic men with less than high school education, those who do not have an identified health care provider or health insurance, and who defer health care because of cost could be ways to improve the outcome of acute vascular events among the U.S. Hispanic adult male population.

    Introduction: This study aimed to examine the effects of induced inflammatory tooth pain on anxiety level in adult male rats. Methods: The mandibular incisors of 56 adult male rats were cut off and prefabricated crowns were fixed on the teeth. Formalin and capsaicin were injected intradentally to induce inflammatory tooth pain. Diazepam treated group received diazepam 30 minutes before intradental injection. The anxiety-related behavior was evaluated with elevated plus maze test. Results: Intradental application of chemical noxious stimuli, capsaicin and formalin, significantly affected nociceptive behaviors (P<0.001). Capsaicin (P<0.001) and formalin (P<0.01) significantly increased the anxiety levels in rats by decrease in the duration of time spent in open arm and increase in the duration of time spent in closed arm. Rats that received capsaicin made fewer open arm entries compared to the control animals (P<0.05). Capsaicin (P<0.001) and formalin (P<0.01) treated rats showed more stretch attend postures compared to the control and sham operated animals. In diazepampretreated rats, capsaicin induced algesic effect was prevented (P<0.001). Conclusion: Inflammatory pulpal pain has anxiogenic effect on rats, whereas diazepam premedication showed both anxiolytic and pain reducing effects. PMID:27563419

    One potential source of heterogeneity within autism spectrum conditions (ASC) is language development and ability. In 80 high-functioning male adults with ASC, we tested if variations in developmental and current structural language are associated with current neuroanatomy. Groups with and without language delay differed behaviorally in early social reciprocity, current language, but not current autistic features. Language delay was associated with larger total gray matter (GM) volume, smaller relative volume at bilateral insula, ventral basal ganglia, and right superior, middle, and polar temporal structures, and larger relative volume at pons and medulla oblongata in adulthood. Despite this heterogeneity, those with and without language delay showed significant commonality in morphometric features when contrasted with matched neurotypical individuals (n = 57). In ASC, better current language was associated with increased GM volume in bilateral temporal pole, superior temporal regions, dorsolateral fronto-parietal and cerebellar structures, and increased white matter volume in distributed frontal and insular regions. Furthermore, current language–neuroanatomy correlation patterns were similar across subgroups with or without language delay. High-functioning adult males with ASC show neuroanatomical variations associated with both developmental and current language characteristics. This underscores the importance of including both developmental and current language as specifiers for ASC, to help clarify heterogeneity. PMID:25249409

    The prevalence of obesity and overweight is socially patterned, with higher prevalence among women, racial/ethnic minorities, and those with lower socio-economic status. Contextual factors also affect obesity risk. However, an omitted factor has been incarceration, particularly since it disproportionately affects minorities. This study examines the effects of incarceration on adult male body mass index (BMI) in the United States over the life course, and whether effects vary by race/ethnicity and education. BMI trajectories were analyzed over age using growth curve models of men ages 18-49 from the National Longitudinal Survey of Youth panel study. BMI was based on self-reported height/weight (kg/m(2)). Being currently incarcerated increased BMI, but the effect varied by race/ethnicity and education: blacks experienced the largest increases, while effects were lowered for men with more education than a high school diploma. Cumulative exposure to prison increased BMI for all groups. These results suggest a differential effect of incarceration on adult male BMI among some racial/ethnic-education minority groups. Particularly given that these groups are most commonly imprisoned, incarceration may help structure obesity disparities and disadvantage across the life course.

    Prior research has indicated that self-reported violent media exposure is associated with poorer performance on some neuropsychological tests in adolescents. This study aimed to examine the relationship of executive functioning to violent television viewing in healthy young adult males and examine how brain structure is associated with media exposure measures. Sixty-five healthy adult males (ages 18-29) with minimal video game experience estimated their television viewing habits over the past year and, during the subsequent week, recorded television viewing time and characteristics in a daily media diary. Participants then completed a battery of neuropsychological laboratory tests quantifying executive functions and underwent a magnetic resonance imaging (MRI) scan. Aggregate measures of executive functioning were not associated with measures of overall television viewing (any content type) during the past week or year. However, the amount of television viewing of violent content only, as indicated by both past-year and daily diary measures, was associated with poorer scores on an aggregate score of inhibition, interference control and attention, with no relationship to a composite working memory score. In addition, violent television exposure, as measured with daily media diaries, was associated with reduced frontoparietal white matter volume. Future longitudinal work is necessary to resolve whether individuals with poor executive function and slower white matter growth are more drawn to violent programming, or if extensive media violence exposure modifies cognitive control mechanisms mediated primarily via prefrontal cortex. Impaired inhibitory mechanisms may be related to reported increases in aggression with higher media violence exposure.

    The purposes of this investigation were to compare psychological distress among cancer survivors' social network members with different relationships with the survivors and to compare their reported levels of distress with population norms. Participants in this investigation included spouses/significant others (n = 153), siblings (n = 11), adult children (n = 25), parents (n = 10), cousins (n = 6), and friends/others (n = 10) of English or Spanish speaking women with breast cancer and English speaking men with prostate cancer. Network members reported on their symptoms of depression, positive and negative affect, anxiety, and relationship satisfaction. The psychological distress among all relationship types was similar. Spouses, and to a lesser extent, adult children were the only groups whose levels of psychological distress were above population norms. Relationship satisfaction was negatively associated with social network members' psychological distress, and female network members had higher levels of depression than male network members due, in part, to higher perceived stress among female network members. These findings highlight the need to consider the potentially deleterious impact of cancer not just on survivors' spouses, but on other social network members as well and to make services available to network members who may play an important role in the survivor's care and adjustment.

    2011-12-01

    Studies have shown that male circumcision greatly reduces the risk for heterosexual transmission of HIV, other sexually transmitted infections, infant urinary tract infections, penile cancer, and other adverse health outcomes. Given recent data regarding these health benefits and the cost-effectiveness of newborn male circumcision, national policy makers are developing new recommendations regarding circumcision for newborn, adolescent, and adult males. To investigate the implications, this study assessed insurance coverage and reimbursement for routine newborn and adult male circumcision in private and public health plans in 2009. We found that coverage varies across private and public payers. Private insurance provides far broader coverage than state Medicaid programs for routine newborn male circumcision. Specifically, Medicaid programs in seventeen states do not cover it, even though low-income populations have a higher risk of HIV and other sexually transmitted diseases compared to higher-income groups. For adult male circumcision, coverage is generally sparse across public and private plans. Presentation of evidence-based recommendations--for example, from the Centers for Disease Control and Prevention--may be necessary if coverage for newborn and adult male circumcision is to be expanded.

  15. Subadult experience influences adult mate choice in an arthropod: exposed female wolf spiders prefer males of a familiar phenotype.

    Current sexual selection theory proposes several potential mechanisms driving the evolution of female mating preferences, few of which involve social interactions. Although vertebrate examples of socially influenced mating preferences do exist, the invertebrate examples are virtually nonexistent. Here I demonstrate that the mating preferences of female wolf spiders can be acquired through exposure as subadults to unrelated, sexually active adult males. I first conducted exposure trials during which subadult females of the wolf spider Schizocosa uetzi were allowed to interact with mature males of an experimentally manipulated phenotype (either black or brown forelegs). After maturation, these previously exposed females were paired with a male of either a familiar or unfamiliar manipulated phenotype for mate-choice trials. Subadult females that were exposed to directed courtship by mature males of a particular morphological phenotype were subsequently more likely to mate with a male of a familiar phenotype as adults. Furthermore, females that were exposed as subadults were more likely, as adults, to cannibalize a courting male with an unfamiliar phenotype. Unexposed females did not distinguish between phenotypes in either mate choice or cannibalism frequency. These results suggest a previously uncharacterized mechanism influencing the origin of female mating preferences and ultimately the evolution of male traits: subadult experience. This study also stresses the potential importance of learning and memory on adult mate choice in an arthropod.

    In 2014, the California Department of Public Health was notified by a local health department of a diagnosis of acute human immunodeficiency virus (HIV) infection* and rectal gonorrhea in a male adult film industry performer, aged 25 years (patient A). Patient A had a 6-day history of rash, fever, and sore throat suggestive of acute retroviral syndrome at the time of examination. He was informed of his positive HIV and gonorrhea test results 6 days after his examination. Patient A had a negative HIV-1 RNA qualitative nucleic acid amplification test (NAAT)(†) 10 days before symptom onset. This investigation found that during the 22 days between the negative NAAT and being informed of his positive HIV test results, two different production companies directed patient A to have condomless sex with a total of 12 male performers. Patient A also provided contact information for five male non-work-related sexual partners during the month before and after his symptom onset. Patient A had additional partners during this time period for which no locating information was provided. Neither patient A nor any of his interviewed sexual partners reported taking HIV preexposure prophylaxis (PrEP). Contact tracing and phylogenetic analysis of HIV sequences amplified from pretreatment plasma revealed that a non-work-related partner likely infected patient A, and that patient A likely subsequently infected both a coworker during the second film production and a non-work-related partner during the interval between his negative test and receipt of his positive HIV results. Adult film performers and production companies, medical providers, and all persons at risk for HIV should be aware that testing alone is not sufficient to prevent HIV transmission. Condom use provides additional protection from HIV and sexually transmitted infections (STIs). Performers and all persons at risk for HIV infection in their professional and personal lives should discuss the use of PrEP with their medical

    Environmental factors have long been known to regulate brain plasticity. We investigated the potential influence of social experience on ocular dominance plasticity. Fully adult female or male mice were monocularly deprived for four days and kept a) either alone or in pairs of the same sex and b) either in a small cage or a large, featureless arena. While mice kept alone did not show ocular dominance plasticity, no matter whether in a cage or in an arena, paired female mice in both environmental conditions displayed a shift of ocular dominance towards the open eye. Paired male mice, in contrast, showed no plasticity in the cage, but a very strong ocular dominance shift in the arena. This effect was not due to increased locomotion, since the covered distance was similar in single and paired male mice in the arena, and furnishing cages with a running wheel did not enable ocular dominance plasticity in cage-housed mice. Confirming recent results in rats, the plasticity-enhancing effect of the social environment was shown to be mediated by serotonin. Our results demonstrate that social experience has a strong effect on cortical plasticity that is sex-dependent. This has potential consequences both for animal research and for human education and rehabilitation.

    The aim of the present study was to clarify the effect of photoperiod on secretory patterns of growth hormone (GH) in male goats. Adult male goats were kept at 20°C with an 8-h or 16-h light photoperiod, and secretory patterns of GH secretion were compared. In addition, plasma profiles of prolactin (PRL), insulin-like growth factor-I (IGF-I) and testosterone (T) were also examined to characterize GH secretion. GH was secreted in a pulsatile manner. There was no significant difference in pulse frequency between the 8-h and 16-h photoperiods. However, GH pulse amplitude tended to be greater in the group with the 16-h photoperiod (P = 0.1), and mean GH concentrations were significantly greater in the 16-h photoperiod (P < 0.05). The GH-releasing response to GH releasing hormone was greater in the 16-h than 8-h photoperiod (P < 0.05). Plasma PRL and IGF-I levels were higher in the 16-h than 8-h photoperiod (P < 0.05). In contrast, plasma T levels were lower in the 16-h photoperiod (P < 0.05). These results show that a long light photoperiod enhances the secretion of GH as well as PRL and IGF-I, but reduces plasma T concentrations in male goats.

    Recent brain imaging research has revealed oxytocin (OT) effects on an individual's brain activity during social interaction but tells little about whether and how OT modulates the coherence of inter-brain activity related to two individuals' coordination behavior. We developed a new real-time coordination game that required two individuals of a dyad to synchronize with a partner (coordination task) or with a computer (control task) by counting in mind rhythmically. Electroencephalography (EEG) was recorded simultaneously from a dyad to examine OT effects on inter-brain synchrony of neural activity during interpersonal coordination. Experiment 1 found that dyads showed smaller interpersonal time lags of counting and greater inter-brain synchrony of alpha-band neural oscillations during the coordination (vs control) task and these effects were reliably observed in female but not male dyads. Moreover, the increased alpha-band inter-brain synchrony predicted better interpersonal behavioral synchrony across all participants. Experiment 2, using a double blind, placebo-controlled between-subjects design, revealed that intranasal OT vs placebo administration in male dyads improved interpersonal behavioral synchrony in both the coordination and control tasks but specifically enhanced alpha-band inter-brain neural oscillations during the coordination task. Our findings provide first evidence that OT enhances inter-brain synchrony in male adults to facilitate social coordination.

    Our previous study showed that prenatal nicotine exposure could increase the heart rate of adult male offspring rats, but little is known about the mechanism. The aim of this study was to investigate the mechanism. Nicotine was subcutaneously administered to pregnant rats at a dose of 1.5mgkg(-1) from the gestational days 3-21; the control group received the same volume of saline by the same route. The offsprings' heart weight, ejection function, ultrastructure, and blood hormones were determined. The present study exhibited that prenatal nicotine exposure significantly decreased the offsprings' heart and body weight at gestational day 21 and at day 15 after birth, but had no effect on the heart and body weight at 90 days after birth. The hearts were fibrosed in the nicotine exposed male offsprings, and the heart ejection functions of the nicotine male offsprings at 90 days after birth were decreased, including SV, FS and EF. In addition, prenatal nicotine exposure significantly increased the offspring's blood adrenaline and norepinephrine levels. These data suggest that the increased heart rate caused by prenatal nicotine exposure may be a result of myocardial fibrosis, which leads to heart function decreases, and these data imply a myocardial fibrosis risk of prenatal nicotine exposure.

    Purpose: To compare the health practice of Hodgkin's lymphoma (HL) survivors and their siblings, and to assess the impact of socioeconomic status and disease history on health practice of HL survivors. Methods and Materials: We conducted a questionnaire study on long-term HL survivors and their siblings on health care utilization, health habits, and screening behavior. Results: A total of 511 HL survivors (response rate of 50%, including survivors lost to contact) and 224 siblings (response rate, 58%) participated. Median time from HL diagnosis was 15 years. Significantly more survivors than siblings had a physical examination in the past year (63% vs. 49%, p = 0.0001). Male survivors were significantly more likely than siblings to perform monthly self-testicular examinations (19% vs. 9%, p = 0.02). Among survivors, higher household income (p = 0.01) independently predicted for having had a physical examination in the past year. Lower educational level (p = 0.0004) and history of relapsed HL (p = 0.03) were independent predictors for smoking, moderate/heavy alcohol use, and/or physical inactivity. Conclusions: Compared with siblings, long-term HL survivors have a higher level of health care utilization and better screening practice. Survivors from lower socioeconomic background had lower adherence to routine health care and greater report of unhealthy habits. Survivors with history of relapsed HL were also more likely to engage in unhealthy habits.

    Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age. A sex-matched and age-matched population-based control cohort was used for comparison (n=45,449). Demographic and socioeconomic data were obtained from national registers and explored by discrete-time Cox regression analyses. Childhood cancer survivors had a reduced rate of cohabitation [rate ratio (RR) 0.78; 95% confidence interval (CI): 0.73-0.83], owing to lower rates among survivors of both noncentral nervous system (CNS) tumors (RR 0.88; 95% CI: 0.83-0.95) and CNS tumors (RR 0.52; 95% CI: 0.45-0.59). Male CNS tumor survivors had a nonsignificantly lower rate (RR 0.47; 95% CI: 0.38-0.58) than females (RR 0.56; 95% CI: 0.47-0.68). The rates of separation were almost identical to those of controls. In conclusion, the rate of cohabitation was lower for all childhood cancer survivors than for the population-based controls, with the most pronounced reduction among survivors of CNS tumors. Mental deficits after cranial irradiation are likely to be the major risk factor.

    The development of paediatric intensive care has contributed to the improved survival of critically ill children. Physical and psychological sequelae and consequences for quality of life (QoL) in survivors might be significant, as has been determined in adult intensive care unit (ICU) survivors. Awareness of sequelae due to the original illness and its treatment may result in changes in treatment and support during and after the acute phase. To determine the current knowledge on physical and psychological sequelae and the quality of life in survivors of paediatric intensive care, we undertook a computerised comprehensive search of online databases for studies reporting sequelae in survivors of paediatric intensive care. Studies reporting sequelae in paediatric survivors of cardiothoracic surgery and trauma were excluded, as were studies reporting only mortality. All other studies reporting aspects of physical and psychological sequelae were analysed. Twenty-seven studies consisting of 3,444 survivors met the selection criteria. Distinct physical and psychological sequelae in patients have been determined and seemed to interfere with quality of life. Psychological sequelae in parents seem to be common. Small numbers, methodological limitations and quantitative and qualitative heterogeneity hamper the interpretation of data. We conclude that paediatric intensive care survivors and their parents have physical and psychological sequelae affecting quality of life. Further well-designed prospective studies evaluating sequelae of the original illness and its treatment are warranted. PMID:17823815

    Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; P<0.01 for both). The intraoperative and postoperative pain scores were significantly lower in the stapler group than in the conventional group (0.8 ± 0.5 vs 2.4 ± 0.8 and 4.0 ±0.9 vs 5.8 ± 1.0, respectively; P<0.01 for both). Additionally, the stapler group had significantly fewer complications than the conventional group (2.7% vs 7.8%, respectively; P<0.01). However, the treatment costs in the stapler group were much higher than those in the conventional group (US$356.60 ± 8.20 vs US$126.50 ± 7.00, respectively; P<0.01). Most patients (388/441, 88.0%) who underwent stapler circumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

    The light/dark (LD) test is a commonly used rodent test of unconditioned anxiety-like behavior that is based on an approach/avoidance conflict between the drive to explore novel areas and an aversion to brightly lit, open spaces. We used the LD test to investigate developmental differences in behavior between adolescent (postnatal day (PN) 28-34) and adult (PN67-74) male rats. We investigated whether LD behavioral measures reflect anxiety-like behavior similarly in each age group using factor analysis and multiple regression. These analyses showed that time in the light compartment, percent distance in the light, rearing, and latency to emerge into the light compartment were measures of anxiety-like behavior in each age group, while total distance traveled and distance in the dark compartment provided indices of locomotor activity. We then used these measures to assess developmental differences in baseline LD behavior and the response to anxiogenic drugs. Adolescent rats emerged into the light compartment more quickly than adults and made fewer pokes into the light compartment. These age differences could reflect greater risk taking and less risk assessment in adolescent rats than adults. Adolescent rats were less sensitive than adults to the anxiogenic effects of the benzodiazepine inverse agonist N-methyl-β-carboline-3-carboxamide (FG-7142) and the α₂ adrenergic antagonist yohimbine on anxiety-like behaviors validated by factor analysis, but locomotor variables were similarly affected. These data support the results of the factor analysis and indicate that GABAergic and noradrenergic modulation of LD anxiety-like behavior may be immature during adolescence.

    Objective To identify risk factors for adverse psychological outcomes among adult siblings of long-term survivors of childhood cancer. Methods Cross-sectional, self-report data from 3,083 adult siblings (mean age 29 years, range 18-56 years) of 5+ year survivors of childhood cancer were analyzed to assess psychological outcomes as measured by the Brief Symptom Inventory-18 (BSI-18). Sociodemographic and health data, reported by both the siblings and their matched cancer survivors were explored as risk factors for adverse sibling psychological outcomes through multivariable logistic regression. Results Self-reported symptoms of psychological distress, as measured by the global severity index of the BSI-18, were reported by 3.8% of the sibling sample. Less than 1.5% of siblings reported elevated scores on two or more of the subscales of the BSI-18. Risk factors for sibling depression included having a survivor brother (OR 2.22, 95% CI 1.42-3.55), and having a survivor with impaired general health (OR 2.15, 95% CI 1.18-3.78). Siblings who were younger than the survivor reported increased global psychological distress (OR 1.81, 95% CI 1.05-3.12), as did siblings of survivors reporting global psychological distress (OR 2.32, 95% CI 1.08-4.59). Siblings of sarcoma survivors reported more somatization than did siblings of leukemia survivors (OR 2.07, 95% CI 1.05-3.98). Conclusions These findings suggest that siblings of long-term childhood cancer survivors are psychologically healthy in general. There are, however, small subgroups of siblings at risk for long-term psychological impairment who may benefit from preventive risk-reduction strategies during childhood while their sibling with cancer is undergoing treatment.

    Increasing attention is paid on functional limitations and disability among people with chronic diseases. However, only few studies have explored disability in persons with acute myocardial infarction (AMI). The objective of this study was to provide a description of disability and to identify determinants of disability in a population-based sample of long-term AMI survivors. The sample consisted of 1943 persons (35-85years) with AMI from the German population-based MONICA/KORA Myocardial Infarction Registry, who responded to a postal follow-up survey in 2011. Disability was assessed with the 12-item version of the World Health Organization Disability Schedule (WHODAS). Multivariate linear regression models were established in order to identify socioeconomic and clinical factors, risk factors and comorbidities which are associated with disability. The mean WHODAS score for the total sample was 7.86±9.38. The regression model includes 26 variables that explained 37.2% of the WHODAS variance. Most of the explained variance could be attributed to the presence of depression, female sex, joint disorders, digestive disorders, and stroke. Depression was the most important determinant of disability in both sexes. Replacement of single comorbidities by the total number of comorbidities resulted in a model with 15 variables explaining 31.9% of the WHODAS variance. Most of the variance was explained by the number of comorbidities. Further significant determinants of disability were female sex, low education level, angina pectoris, and no revascularization therapy. In AMI patients, the number of comorbidities and particularly the presence of depression are important determinants of disability and should be considered in post-AMI health care.

    The Centres for Disease Control and Prevention have defined a chronic diseases as an "illnesses that are prolonged, do not resolve spontaneously, and are rarely cured completely". Approximately 20% of all children have a chronic illness and 65% of them the illness is severe enough to interfere with daily activities. Failure of pubertal growth, delay or absence of sexual development, infertility and sexual dysfunction due to hypogonadism and defective spermatogenesis are well recognized disturbances among adolescents and young male adult patients with chronic diseases. The causes are multifactorial and can be due to disease itself, associated complications or drugs. Haemoglobinopathies, endocrine disorders, gastrointestinal and renal diseases are some examples that frequently cause some degree of disability. Infertility affects the future quality of life of these patients and is a predictor of stress in current and future relationships. Health care providers often neglect the reproductive health of chronically ill adolescents and young adults, although many studies indicate that they are sexually active and interested in knowing about their future fertility. This review article provides an overview of the literature concerning the impact of some chronic diseases in adolescents and young adults on reproductive health but will not address patients with cancer because it has been tackled adequately in the literature.MEDLINE database search of English-language medical journal articles published between 1975 and 2012 for papers related to reproductive health in adolescents and young adults with chronic diseases since childhood was done. Several Authors, recommend that all young adult patients with severe/prolonged chronic disease in childhood should be offered reproductive health care in a specialized center with appropriate expertise, involving a multidisciplinary team, including endocrinologists, andrologists, geneticists, psychologists, urologists and specialist

    The effect of water restriction on the pituitary-gonadal axis has been studied in adult male rats. Water restriction did not modify FSH, LH and testosterone levels. However, both LH and testosterone responses to acute noise stress were impaired by water restriction. It was unlikely that the inhibition of the pituitary-gonadal response to stress was due to an alteration of the circadian pattern of LH since no evidence for such a daily rhythm was found in either of the two experimental groups. The effects of water restriction on the pituitary-gonadal axis appear to be at least partially a consequence of the resulting reduction in food intake, so that the pituitary-gonadal response to stress would be a more sensitive index of abnormalities induced by protein-calorie deficit than basal concentrations of LH, FSH, or T.

    Official demographic and offense history data (n = 362) and confidential self-report data on paraphilic interests and behavior (n = 221) obtained on adult males convicted of sexual offenses against children were analyzed. Considerable criminal diversity was observed, with all standard categories of offenses represented in offenders' criminal histories. Most (86%) of the offenders' previous convictions were for nonsexual offenses, and most (92%) of the recidivist offenders had previously been convicted of at least one nonsexual offense. The prevalence of diagnosable paraphilias was low, with only 5% meeting formal diagnostic criteria for multiple (two or more) paraphilias other than pedophilia. Sexual offenders' paraphilic interests were unrelated to the extent of their sexual offense convictions but were significantly related to the extent of their nonsexual offense convictions. The results are better explained by a general theory of crime than by traditional clinical conceptions linking sexual offenses specifically with sexual psychopathology.

    A recent analysis of leukaemia mortality in Japanese A-bomb survivors has applied descriptive models, collected together from previous studies, to derive a joint excess relative risk estimate (ERR) by multi-model inference (MMI) (Walsh and Kaiser in Radiat Environ Biophys 50:21-35, 2011). The models use a linear-quadratic dose response with differing dose effect modifiers. In the present study, a set of more than 40 models has been submitted to a rigorous statistical selection procedure which fosters the parsimonious deployment of model parameters based on pairwise likelihood ratio tests. Nested models were consequently excluded from risk assessment. The set comprises models of the excess absolute risk (EAR) and two types of non-standard ERR models with sigmoidal responses or two line spline functions with a changing slope at a break point. Due to clearly higher values of the Akaike Information Criterion, none of the EAR models has been selected, but two non-standard ERR models qualified for MMI. The preferred ERR model applies a purely quadratic dose response which is slightly damped by an exponential factor at high doses and modified by a power function for attained age. Compared to the previous analysis, the present study reports similar point estimates and confidence intervals (CI) of the ERR from MMI for doses between 0.5 and 2.5 Sv. However, at lower doses, the point estimates are markedly reduced by factors between two and five, although the reduction was not statistically significant. The 2.5 % percentiles of the ERR from the preferred quadratic-exponential model did not fall below zero risk in exposure scenarios for children, adolescents and adults at very low doses down to 10 mSv. Yet, MMI produced risk estimates with a positive 2.5 % percentile only above doses of some 300 mSv. Compared to CI from a single model of choice, CI from MMI are broadened in cohort strata with low statistical power by a combination of risk extrapolations from several

    Habitat selection is an active behavioral process that may vary across spatial and temporal scales. Animals choose an area of primary utilization (i.e., home range) then make decisions focused on resource needs within patches. Dominance may affect the spatial distribution of conspecifics and concomitant habitat selection. Size-dependent social dominance hierarchies have been documented in captive alligators, but evidence is lacking from wild populations. We studied habitat selection for adult male American alligators (Alligator mississippiensis; n = 17) on the Pearl River in central Mississippi, USA, to test whether habitat selection was scale-dependent and individual resource selectivity was a function of conspecific body size. We used K-select analysis to quantify selection at the home range scale and patches within the home range to determine selection congruency and important habitat variables. In addition, we used linear models to determine if body size was related to selection patterns and strengths. Our results indicated habitat selection of adult male alligators was a scale-dependent process. Alligators demonstrated greater overall selection for habitat variables at the patch level and less at the home range level, suggesting resources may not be limited when selecting a home range for animals in our study area. Further, diurnal habitat selection patterns may depend on thermoregulatory needs. There was no relationship between resource selection or home range size and body size, suggesting size-dependent dominance hierarchies may not have influenced alligator resource selection or space use in our sample. Though apparent habitat suitability and low alligator density did not manifest in an observed dominance hierarchy, we hypothesize that a change in either could increase intraspecific interactions, facilitating a dominance hierarchy. Due to the broad and diverse ecological roles of alligators, understanding the factors that influence their social dominance

    Genetically modified (GM) plants expressing insecticidal traits offer a new strategy for crop protection. GM-corn contains Bacillus thuringiensis (Bt) genes producing delta endotoxins in the whole plant. Diet can influence the characteristics of the gastrointestinal tract altering its function and structure. The aim of this study was to evaluate the effect of GM-corn on the histological structure of jejunal mucosa of adult male albino rat using different histological, immunohistochemical and morphometrical methods. Twenty adult male albino rats were divided into two equal groups; control and GM-corn fed group administered with 30% GM-corn for 90days. Specimens from the jejunum were processed for light and electron microscopy. Immunohistochemical study was carried out using antibody against proliferating cell nuclear antigen (PCNA). Different morphometrical parameters were assessed. Specimens from GM-corn fed group showed different forms of structural changes. Focal destruction and loss of the villi leaving denuded mucosal surface alternating with stratified areas were observed, while some crypts appeared totally disrupted. Congested blood capillaries and focal infiltration with mononuclear cells were detected. Significant upregulation of PCNA expression, increase in number of goblet cells and a significant increase in both villous height and crypt depth were detected. Marked ultrastructural changes of some enterocytes with focal loss of the microvillous border were observed. Some enterocytes had vacuolated cytoplasm, swollen mitochondria with disrupted cristae and dilated rough endoplasmic reticulum (rER). Some cells had dark irregular nuclei with abnormally clumped chromatin. It could be concluded that consumption of GM-corn profoundly alters the jejunal histological structure.

    Fragile X Syndrome (FraX) is caused by the expansion of a single trinucleotide gene sequence (CGG) on the X chromosome, and is a leading cause of learning disability (mental retardation) worldwide. Relatively few studies, however, have examined the neuroanatomical abnormalities associated with FraX. Of those that are available many included mixed gender populations, combined FraX children and adults into one sample, and employed manual tracing techniques which measures bulk volume of particular regions. Hence, there is relatively little information on differences in grey and white matter content across whole brain. We employed magnetic resonance imaging to investigate brain anatomy in 17 adult males with FraX and 18 healthy controls that did not differ significantly in age. Data were analysed using stereology and VBM to compare (respectively) regional brain bulk volume, and localised grey/white matter content. Using stereology we found that FraX males had a significant increase in bulk volume bilaterally of the caudate nucleus and parietal lobes and of the right brainstem, but a significant decrease in volume of the left frontal lobe. Our complimentary VBM analysis revealed an increased volume of grey matter in fronto-striatal regions (including bilaterally in the caudate nucleus), and increased white matter in regions extending from the brainstem to the parahippocampal gyrus, and from the left cingulate cortex extending into the corpus callosum. People with FraX have regionally specific differences in brain anatomy from healthy controls with enlargement of the caudate nuclei that persists into adulthood.

    The present research was conducted to evaluate the effect of bone marrow derived mesenchymal stem cells (BM-MSCs) as a potential therapeutic tool for improvement of skeletal muscle recovery after induced chemodenervation atrophy by repeated local injection of botulinum toxin-A in the right tibialis anterior muscle of adult male albino rats. Forty five adult Wistar male albino rats were classified into control and experimental groups. Experimental group was further subdivided into 3 equal subgroups; induced atrophy, BM-MSCs treated and recovery groups. Biochemical analysis of serum LDH, CK and Real-time PCR for Bcl-2, caspase 3 and caspase 9 was measured. Skeletal muscle sections were stained with H and E, Mallory trichrome, and Immunohistochemical reaction for Bax and CD34. Improvement in the skeletal muscle histological structure was noticed in BM-MSCs treated group, however, in the recovery group, some sections showed apparent transverse striations and others still affected. Immunohistochemical reaction of Bax protein showed strong positive immunoreaction in the cytoplasm of muscle fibers in the induced atrophy group. BM-MSCs treated group showed weak positive reaction while the recovery group showed moderate reaction in the cytoplasm of muscle fibers. Immunohistochemical reaction for CD34 revealed occasional positive CD34 stained cells in the induced atrophy group. In BM-MSCs treated group, multiple positive CD34 stained cells were detected. However, recovery group showed some positive CD34 stained cells at the periphery of the muscle fibers. Marked improvement in the regenerative capacity of skeletal muscles after BM-MSCs therapy. Hence, stem cell therapy provides a new hope for patients suffering from myopathies and severe injuries.

Size-dependent social dominance hierarchies have been documented in captive alligators, but evidence is lacking from wild populations. We studied habitat selection for adult male American alligators (Alligator mississippiensis; n = 17) on the Pearl River in central Mississippi, USA, to test whether habitat selection was scale-dependent and individual resource selectivity was a function of conspecific body size. We used K-select analysis to quantify selection at the home range scale and patches within the home range to determine selection congruency and important habitat variables. In addition, we used linear models to determine if body size was related to selection patterns and strengths. Our results indicated habitat selection of adult male alligators was a scale-dependent process. Alligators demonstrated greater overall selection for habitat variables at the patch level and less at the home range level, suggesting resources may not be limited when selecting a home range for animals in our study area. Further, diurnal habitat selection patterns may depend on thermoregulatory needs. There was no relationship between resource selection or home range size and body size, suggesting size-dependent dominance hierarchies may not have influenced alligator resource selection or space use in our sample. Though apparent habitat suitability and low alligator density did not manifest in an observed dominance hierarchy, we hypothesize that a change in either could increase intraspecific interactions, facilitating a dominance hierarchy. Due to the broad and diverse ecological roles of alligators, understanding the factors that influence their social dominance

    The present study explored the effects of supplementing male rats with either choline, omega-3 fatty acids, or phytoestrogens, from weaning into early adulthood, on emotionality and hippocampal plasticity. Because of the neuroprotective properties of these nutrients, we hypothesized that they would positively affect both behavior and hippocampal function when compared to non-supplemented control rats. To test this hypothesis, male Sprague Dawley rats were assigned to one of four nutrient conditions after weaning: 1) control (normal rat chow); 2) choline (supplemented in drinking water); 3) omega 3 fatty acids (daily oral supplements); or 4) phytoestrogens (supplemented in chow). After 4 weeks on their respective diets, a subset of rats began 3 weeks of behavioral testing, while the remaining behaviorally naïve rats were sacrificed after 6 weeks on the diets to assess numbers of adult-born hippocampal neurons using the immature neuron marker, doublecortin. The results revealed that choline supplementation affected emotional functioning; compared to rats in other diet conditions, rats in this group were less anxious in an open field and after exposure to predator odor and showed less behavioral despair after forced swimming. Similar behavioral findings were evident following supplementation with omega-3 fatty acids and phytoestrogens supplementation, though not on all tests and not to the same magnitude. Histological findings followed a pattern consistent with the behavioral findings: choline supplementation, followed by omega-3 fatty acid supplementation, but not phytoestrogen supplementation, significantly increased the numbers of new-born hippocampal neurons. Choline and omega −3 fatty acids have similar biological functions—affecting cell membranes, growth factor levels, and epigenetically altering gene transcription. Thus, the present findings suggest that targeting nutrients with these effects may be a viable strategy to combat adult psychopathologies

    Dengue, chikungunya and zika viruses are pathogens with an increasing global impact. In the absence of an approved vaccine or therapy, their management relies on controlling the mosquito vectors. But traditional controls are inadequate, and the range of invasive species such as Aedes albopictus (Asian Tiger Mosquito) is expanding. Genetically modified mosquitoes are being tested, but their use has encountered regulatory barriers and public opposition in some countries. Wolbachia bacteria can cause a form of conditional sterility, which can provide an alternative to genetic modification or irradiation. It is unknown however, whether openly released, artificially infected male Ae. albopictus can competitively mate and sterilize females at a level adequate to suppress a field population. Also, the unintended establishment of Wolbachia at the introduction site could result from horizontal transmission or inadvertent female release. In 2014, an Experimental Use Permit from the United States Environmental Protection Agency approved a pilot field trial in Lexington, Kentucky, USA. Here, we present data showing localized reduction of both egg hatch and adult female numbers. The artificial Wolbachia type was not observed to establish in the field. The results are discussed in relation to the applied use of Wolbachia-infected males as a biopesticide to suppress field populations of Ae. albopictus. PMID:27659038

    Postnatal ad libitum caloric intake superimposed on intrauterine growth restriction (IUGR) is associated with adult-onset obesity, insulin resistance, and type 2 diabetes mellitus (T2DM). We hypothesized that this paradigm of prenatal nutrient deprivation-induced programming can be reversed with the introduction of early postnatal calorie restriction. Ten-month-old male rats exposed to either prenatal nutrient restriction with ad libitum postnatal intake (IUGR), pre- and postnatal nutrient restriction (IPGR), or postnatal nutrient restriction limited to the suckling phase (50% from postnatal [PN]1 to PN21) (PNGR) were compared with age-matched controls (CON). Visceral adiposity, metabolic profile, and insulin sensitivity by hyperinsulinemic-euglycemic clamps were examined. The 10-month-old male IUGR group had a 1.5- to 2.0-fold increase in subcutaneous and visceral fat (P < 0.0002) while remaining euglycemic, insulin sensitive, inactive, and exhibiting metabolic inflexibility (Vo(2)) versus CON. The IPGR group remained lean, euglycemic, insulin sensitive, and active while maintaining metabolic flexibility. The PNGR group was insulin sensitive, similar to IPGR, but less active while maintaining metabolic flexibility. We conclude that IUGR resulted in obesity without insulin resistance and energy metabolic perturbations prior to development of glucose intolerance and T2DM. Postnatal nutrient restriction superimposed on IUGR was protective, restoring metabolic normalcy to a lean and active phenotype.

    In humans, both language and fine motor skills are associated with left-hemisphere specialization, whereas visuospatial skills are associated with right-hemisphere specialization. Individuals with autism spectrum conditions (ASC) show a profile of deficits and strengths that involves these lateralized cognitive functions. Here we test the hypothesis that regions implicated in these functions are atypically rightward lateralized in individuals with ASC and, that such atypicality is associated with functional performance. Participants included 67 male, right-handed adults with ASC and 69 age- and IQ-matched neurotypical males. We assessed group differences in structural asymmetries in cortical regions of interest with voxel-based analysis of grey matter volumes, followed by correlational analyses with measures of language, motor and visuospatial skills. We found stronger rightward lateralization within the inferior parietal lobule and reduced leftward lateralization extending along the auditory cortex comprising the planum temporale, Heschl's gyrus, posterior supramarginal gyrus, and parietal operculum, which was more pronounced in ASC individuals with delayed language onset compared to those without. Planned correlational analyses showed that for individuals with ASC, reduced leftward asymmetry in the auditory region was associated with more childhood social reciprocity difficulties. We conclude that atypical cerebral structural asymmetry is a potential candidate neurophenotype of ASC.

    Cancers and hepatoprotective prevention using traditional medicines have attracted increasing interest. The aim of our study was to characterize the putative protective effects of ethanol and chloroform extracts of Peganum harmala on thiourea-induced diseases in adult male rat. We seek to determine the effects of these plant extracts on body weight, thyroid and endocrine cancer parameters. In addition the putative hepatoprotective effect was checked by the determination of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and the bilirubin level in the blood. Our data show that ethanol and chloroform extracts of Peganum harmala protected the animal against the carcinogenic effects induced by thiourea since neuron-specific enolase (NSE) and thyroglobulin (TG) levels were back to the normal range. In addition, the observed-hepatocytotoxicity after thiourea treatment was greatly reduced (AST and ALT activities were respectively 270 IU/l and 60 IU/l and in the same order of magnitude as in the untreated rats) as well as the bilirubin levels (6 micromol/l) especially for animals receiving the choroform preparation. Therefore we may suggest that extracts of Peganum harmala are efficient to reduce the toxicity induced by thiourea in male rat as far as the above parameters are concerned.

    Patient: Male, 31 Final Diagnosis: Uncomplicated cystitis Symptoms: Cough • dysuria • fever • hematuria Medication: — Clinical Procedure: — Specialty: Infectious Diseases Objective: Unusual clinical course Background: Influenza B viruses cause seasonal epidemics of respiratory illness, circulating concurrently with influenza A viruses. However, virological and clinical knowledge of influenza B viruses is less well advanced than for influenza A, and in particular, complications associated with influenza B infection are not as commonly reported. Complications of influenza B infection predominantly include neurological and musculoskeletal pathologies, while a review of the literature shows that bacterial infections associated with influenza B viruses often involve Gram-positive organisms, with a smaller subset featuring Gram-negative species. Case Report: In this case report we highlight an uncomplicated infection of the urinary tract by Escherichia coli immediately following influenza B infection, in an otherwise healthy adult white male with no prior history of urinary tract infection or structural abnormalities of the renal tract. Conclusions: Bacterial infections complicating influenza B infection may include organisms not commonly associated with the respiratory system, such as Escherichia coli. In addition, bacterial complications of influenza B infection may affect non-respiratory systems, including the genitourinary tract. PMID:28223680

    The prairie vole (Microtus ochrogaster) is a socially monogamous rodent species that forms pair bonds after mating. Recent data have shown that amphetamine (AMPH) is rewarding to prairie voles as it induces conditioned place preferences. Further, repeated treatment with AMPH impairs social bonding in adult prairie voles through a central dopamine (DA)-dependent mechanism. The present study examined the effects of neonatal exposure to AMPH on behavior and central DA activity in adult male prairie voles. Our data show that neonatal exposure to AMPH makes voles less social in an affiliation test during adulthood, but does not affect animals' locomotor activity and anxiety-like behavior. Neonatal exposure to AMPH also increases the levels of tyrosine hydroxylase (TH) and DA transporter (DAT) mRNA expression in the ventral tegmental area (VTA) in the brain, indicating an increase in central DA activity. As DA has been implicated in AMPH effects on behavioral and cognitive functions, altered DA activity in the vole brain may contribute to the observed changes in social behavior.

    Introduction: In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP) among young adult male smokers. Methods: A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18–45 years old. Results: The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811), and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364)  in the sample of higher education young adult males Conclusions: Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers. PMID:25689992

    Neonatal handling has an impact on adult behavior of experimental animals and is associated with rapid and increased palatable food ingestion, impaired behavioral flexibility, and fearless behavior to novel environments. These symptoms are characteristic features of impulsive trait, being controlled by the medial prefrontal cortex (mPFC). Impulsive behavior is a key component of many psychiatric disorders such as attention deficit hyperactivity disorder (ADHD), manic behavior, and schizophrenia. Others have reported a methylphenidate (MPH)-induced enhancement of mPFC functioning and improvements in behavioral core symptoms of ADHD patients. The aims of the present study were: (i) to find in vivo evidence for an association between neonatal handling and the development of impulsive behavior in adult Wistar rats and (ii) to test whether neonatal handling could have an impact on monoamine levels in the mPFC and the pharmacological response to MPH in vivo. Therefore, experimental animals (litters) were classified as: "non-handled" and "handled" (10[Formula: see text]min/day, postnatal days 1-10). After puberty, they were exposed to either a larger and delayed or smaller and immediate reward (tolerance to delay of reward task). Acute MPH (3[Formula: see text]mg/Kg. i.p.) was used to suppress and/or regulate impulsive behavior. Our results show that only neonatally handled male adult Wistar rats exhibit impulsive behavior with no significant differences in monoamine levels in the medial prefrontal cortex, together with a decreased response to MPH. On this basis, we postulate that early life interventions may have long-term effects on inhibitory control mechanisms and affect the later response to pharmacological agents during adulthood.

  8. Non-Parental Adults in the Social and Risk Behavior Networks of Sexual Minority Male Youth

    The presence of non-parental adults (NPAs), or adults outside of caregivers (e.g., extended family, natural mentors), in the lives of adolescents and emerging adults has received a rapidly expanding amount of empirical attention in the last decade. Sexual minority male youth (SMMY) face disproportionate risks of abuse and victimization in relationships with parents and peers. Yet, despite the fact that this group, therefore, may be both potentially vulnerable to negative interpersonal influences but also poised to benefit from additional relationships, NPA involvement in the lives of SMMY is currently not well understood in the extant literature. This study sought to examine and characterize the involvement of NPAs in the social and risk networks of SMMY (n = 175; 54% African American, 21% Hispanic/Latino, 14% Caucasian; ages 17–23). Most SMMY identified at least one NPA, such as friends and grandparents, in their networks. Three categories of relationships were identified, Strictly Social, which only involved social interactions; Complex, which were both social and involved substance use and/or sexual activity; and Risky, which purely consisted of substance use or sexual activity. Relationships were rated as emotionally “closer” among ethnic minority SMMY, although, racial/ethnic similarity between SMMY and NPAs was not associated with relationship closeness. In addition, relationships involving female and heterosexual NPAs were also rated as stronger. These findings suggest the potential usefulness of considering multiple types of relationships between SMMY and NPAs when designing intervention and prevention efforts. Moreover, African American and Latino SMMY, who represent the most vulnerable sub-groups of SMMY in terms of HIV-risk, may be particularly poised to benefit from positive NPA relationships.

    Accumulated data suggests a positive effect of silicon on bone health; however, limited research exists on the silicon content of foods. To further the understanding of the relationship between dietary silicon intake and bone health, a food composition database of commonly consumed foods in Korea is required. For quantitative data on the intake levels of silicon, we analyzed the silicon content of 365 food items commonly consumed in Korea using inductively coupled plasma-atomic emission spectrometry following microwave-assisted digestion. To investigate the dietary silicon intake status and to examine the potential role of dietary silicon intake in the bone status of men, a total of 400 healthy Korean adult males aged 19-25 were observed for their diet intake and calcaneus bone density using the 24-h recall method and quantitative ultrasound, respectively. Clinical markers reflecting bone metabolism such as serum total alkaline phosphatase, N-mid osteocalcin, and type 1 collagen C-terminal telopeptide concentrations were also analyzed. Silicon intake of the subjects was estimated as 37.5 ± 22.2 mg/day. Major food sources of dietary silicon in the Korean male were cereal and cereal products (25.6 % of total silicon intake), vegetables (22.7 %), beverages and liquors (21.2 %), and milk and milk products (7.0 %). Silicon intake correlated positively with age, weight, energy intake, protein intake, calcium intake, and alcohol intake. After adjusted for age, weight, energy intake, protein intake, calcium intake, alcohol intake, smoking cigarettes, and regular exercise status, daily total silicon intake had no correlation with calcaneus bone density and the bone metabolism markers, but silicon intake from vegetables had a positive correlation with serum total alkaline phosphatase activity, a bone formation maker. These findings show the possible positive relationship between dietary silicon intake from vegetables and the bone formation of young adult males. Further

    In adulthood, both alcohol (ethanol) and stress are known to suppress hippocampal neurogenesis in male rats. Similarly, most studies report that prenatal alcohol exposure (PAE) reduces cell proliferation and/or cell survival in the hippocampus of adult males. Furthermore, PAE is known to have marked effects on behavioral and hypothalamic–pituitary–adrenal (HPA) responsiveness to stressors. However, no studies have examined the modulation of adult hippocampal neurogenesis by stress in PAE animals. We hypothesized that, in accordance with previous data, PAE would suppress basal levels of adult hippocampal neurogenesis, and further that stress acting on a sensitized HPA axis would have greater adverse effects on adult hippocampal neurogenesis in PAE than in control rats. Adult male offspring from PAE, pair-fed (PF) control, and ad libitum-fed control (C) groups were subjected to restraint stress (9 days, 1 h/day) or left undisturbed. Rats were then injected with bromodeoxyuridine (BrdU) on day 10, perfused 24 h (proliferation) or 3 weeks (survival) later, and brains processed for BrdU immunohistochemistry. We found that (1) under non-stressed conditions, PAE rats had a small but statistically significant suppressive effect on levels of hippocampal neurogenesis and (2) unexpectedly, repeated restraint stress significantly reduced neurogenesis in C and PF, but not PAE rats. We speculate that the failure of PAE males to mount an appropriate (i.e. suppressive) neurogenic response to stressors, implies reduced plasticity and adaptability or resilience, which could impact negatively on hippocampal structure and function.

    Using routine data from three clinics offering care to survivors of sexual violence (SV) in Monrovia, Liberia, we describe the characteristics of SV survivors and the pattern of SV and discuss how the current approach could be better adapted to meet survivors' needs. There were 1500 survivors seeking SV care between January 2008 and December 2009. Most survivors were women (98%) and median age was 13 years (Interquartile range: 9-17 years). Sexual aggression occurred during day-to-day activities in 822 (55%) cases and in the survivor's home in 552 (37%) cases. The perpetrator was a known civilian in 1037 (69%) SV events. Only 619 (41%) survivors sought care within 72 h. The current approach could be improved by: effectively addressing the psychosocial needs of child survivors, reaching male survivors, targeting the perpetrators in awareness and advocacy campaigns and reducing delays in seeking care.

    Background Three National Health and Morbidity Surveys (NHMSs) had been conducted in Malaysia in 10-year intervals from 1986–2006. Based on the latest NHMS survey in 2006, we describe the prevalence of smoking and identify the social and demographic factors associated with smoking among adult males in Malaysia. Methods A cross-sectional study among 15,639 Malaysian adult males aged 18 years and above was conducted using proportional to size stratified sampling method. The socio-demographic variables examined were level of education, occupation, marital status, residential area, age group and monthly household income. Results The prevalence of smoking among adult males in Malaysia was 46.5% (95% CI: 45.5–47.4%), which was 3% lower than a decade ago. Mean age of smoking initiation was 18.3 years, and mean number of cigarettes smoked daily was 11.3. Prevalence of smoking was highest among the Malays (55.9%) and those aged 21–30 years (59.3%). Smoking was significantly associated with level of education (no education OR 2.09 95% CI (1.67–2.60), primary school OR 1.95, 95% CI (1.65–2.30), secondary school OR 1.88, 95% CI (1.63–2.11), with tertiary education as the reference group).

    In order to attract females, male golden-collared manakins gather in leks and perform a complex display consisting of acrobatics accompanied by loud "wingsnapping". During this display, males show off their yellow beard and yellow, black, and green plumage that is striking in comparison to the dull green plumage of young males and females. We investigated the role of testosterone (T) in activating the display of manakins and in stimulating the growth of the adult male plumage. T regulates song, copulation, and territorial aggression in temperate species. In tropical species, however, T levels can be relatively low year round, which has raised questions about the involvement of T in courtship display and male aggression in these species. In neither temperate nor tropical species has the role of hormones in the shift from juvenile to adult plumage been well studied. Therefore, we implanted green-plumaged birds and adult males with either a T pellet or an inert pellet (controls) and observed the display behaviors of these birds in the field and in captivity. In captive birds, we also plucked feathers from sexually dimorphic regions and observed color and regeneration rate of new feathers. We found that birds implanted with T increased several display behaviors compared to controls. All plucked feathers grew back the same color as prior to treatment; however, we observed some differences in feather growth rate between T-treated birds and controls.

    Objective: To evaluate esthetics perception and satisfaction of the facial profile among Iranian male adolescents and adults. Materials and Methods: In this cross-sectional study, male subjects referred to Orthodontic Department of Mashhad Dental School were enrolled (n = 84) and were divided into two groups: Adolescents (n = 39), and adults (n = 45). They were also assigned to straight, convex, or concave profile groups based on the facial profile angle (G-Sn-Pog’). An ideal silhouette of the lower facial profile was designed in Adobe® Photoshop® CS2 software (Kansas, USA). Then, eight other silhouettes representing different relations of the maxilla and mandible were constructed. Patients were asked to use numbers 1–10 to rank the facial profiles in the order of the attractiveness, and choose a silhouette that best closely resembled their own profile. Moreover, using a questionnaire patients were asked to rank their satisfaction with their profile, and asked to assign a number (1–5) to each question as follows; one represented the least satisfaction, while five reflected the highest satisfaction. Results: Adult and adolescent subjects with straight (adults: 12.0 ± 1.9, adolescents: 12.8 ± 1.05) and concave (adults: 10.0 ± 2.14, adolescents: 10.0 ± 2.08) profile showed the highest and the least satisfaction with their own profile, respectively. Both adult and adolescent group selected “retrognathic maxilla, prognathic mandible” as the least attractive profile. Overall, “straight” and “bimaxillary dentoalveolar retrusion” were chosen as the most attractive silhouettes in adolescent and adults, respectively. In comparison to a professional opinion (clinician ranking), 42.9% of adolescents and 22% of adults were able to correctly diagnose their own profiles type. Conclusion: Most of the male adolescents and especially adults diagnosis of their own profile differed with a professional assessment. PMID:27127750

    A significant number of youths use cigarettes, and more than half of the youths who smoke daily also use illicit drugs. The focus of these studies is on how exposure to nicotine affects subsequent responses to both nicotine and cannabinoids in adolescents compared with adults. We have shown previously that chronic treatment with nicotine produces sensitization to its locomotor-activating effects in female and adult rats but not male adolescent rats. To better understand the effects of nicotine on adolescent and adult rats, rats were injected with nicotine or saline for 7 days and, on day 8, either challenged with delta-9-tetrahydrocannabinol (Δ9-THC) or the cannabinoid agonist CP 55,940 and tested for locomotor activity, or the brains were removed for quantitative autoradiography studies of the cannabinoid1 receptor. A separate group of rats was treated with nicotine plus the cannabinoid antagonist AM 251 and then challenged with CP 55,940. In adolescent male rats, nicotine administration led to sensitization to the locomotor-decreasing effects of both Δ9-THC and CP 55,940, but in adult male rats, the response to either drug was unchanged compared to controls. The effect of nicotine on CP 55,940-mediated locomotor activity was blocked by co-administration of AM 251 with the nicotine. Further, cannabinoid receptor density was increased in the prelimbic prefrontal cortex, ventral tegmental area, and select regions of the hippocampus in adolescent male rats pretreated with nicotine compared to vehicle-treated controls. There were no significant changes in cannabinoid receptor binding, however, in any of the brain regions examined in adult males pretreated with nicotine. The prelimbic prefrontal cortex and the hippocampus have been shown previously to be involved in stimulant reinforcement; thus it is possible that these changes contribute to the unique behavioral effects of chronic nicotine and subsequent drug administration in adolescents compared with adults.

    The rationale for our study was to determine the pattern of ethanol drinking by the high alcohol-drinking (HAD) replicate lines of rats during adolescence and adulthood in both male and female rats. Rats were given 30 days of 24 h free-choice access to ethanol (15%, v/v) and water, with ad lib access to food, starting at the beginning of adolescence (PND 30) or adulthood (PND 90). Water and alcohol drinking patterns were monitored 22 h/day with a "lickometer" set-up. The results indicated that adolescent HAD-1 and HAD-2 males consumed the greatest levels of ethanol and had the most well defined ethanol licking binges among the age and sex groups with increasing levels of ethanol consumption throughout adolescence. In addition, following the first week of adolescence, male and female HAD-1 and HAD-2 rats differed in both ethanol consumption levels and ethanol licking behavior. Adult HAD-1 male and female rats did not differ from one another and their ethanol intake or licking behaviors did not change significantly over weeks. Adult HAD-2 male rats maintained a relatively constant level of ethanol consumption across weeks, whereas adult HAD-2 female rats increased ethanol consumption levels over weeks, peaking during the third week when they consumed more than their adult male counterparts. The results indicate that the HAD rat lines could be used as an effective animal model to examine the development of ethanol consumption and binge drinking in adolescent male and female rats providing information on the long-range consequences of adolescent alcohol drinking.

    To determine whether currently used sources of resistance (soybean Plant Introductions [PI] 548402, 88788, 90763, 437654, 209332, 89772, and 548316) influence sex ratios in H. glycines, four inbred lines of the nematode characterized by zero or high numbers of females on resistant soybean were used to observe the number of adult males produced. Nematodes were allowed to infect soybean roots for 5 days in pasteurized sand. Infected plants were washed and transferred to hydroponic culture tubes. Males were collected every 2 to 3 days up to 30 days after infestation (DAI), and females were collected at 30 DAI. Resistance that suppressed adult females also altered adult male numbers. On PI 548402, 90763, and 437654, male numbers were low and close to zero, whereas on PI 88788, male numbers were higher (α = 0.05). In a separate experiment, the same PIs were infected by an inbred line that tested as an HG Type 0 (i.e., the numbers of females that developed on each PI were less than 10% of the number that developed on the standard susceptible soybean cultivar Lee). In this experiment, male numbers were similar to female numbers on PI 548402, 90763, 437654, and 89772, whereas male numbers on PI 88788, 209332, and 548316 were higher than those of females (α = 0.05). In all experiments, the total number of adults that developed to maturity relative to the number of second-stage juveniles that initially penetrated the root was less on resistant than on susceptible soybean (P ≤ 0.05), indicating that resistance influenced H. glycines survival and not sexual development.

    Background Available data suggest that childhood cancer survivors (CCSs) are comparable to the general population on many lifestyle parameters. However, little is known about minority CCSs. This cross-sectional study describes and compares the body mass index (BMI) and health behaviors of African-American, Hispanic and White survivors to each other and to non-cancer controls. Methods Participants included 452 adult CCS (150 African-American, 152 Hispanic, 150 white) recruited through four childhood cancer treating institutions and 375 ethnically-matched non-cancer controls (125 in each racial/ethnic group) recruited via targeted digit dial. All participants completed a 2-hour in-person interview. Results Survivors and non-cancer controls reported similar health behaviors. Within survivors, smoking and physical activity were similar across racial/ethnic groups. African-American and Hispanic survivors reported lower daily alcohol use than whites, but consumed unhealthy diets and were more likely to be obese. Conclusions This unique study highlights that many minority CCSs exhibit lifestyle profiles that contribute to increased risk for chronic diseases and late effects. Recommendations for behavior changes must consider the social and cultural context in which minority survivors may live. PMID:25564774

    This research was carried out to examine the hypothesis that the absence of fathers promotes a different spacing behaviour in juveniles Calomys musculinus at the beginning of the breeding period. The study was carried out in four 0.25-ha enclosures (two control and two experimental), in a natural pasture, between November 2003 and February 2004. In this study the fathers were removed from the experimental enclosures after juveniles were born. Home-range size depended on sex of juveniles and treatment (father removal). In control and experimental enclosures, female home-range sizes were always smaller than male home-ranges. Male home-ranges were always larger in experimental enclosures than in control enclosures. Treatment and overlap type (intra- and inter-sexual) were not independent. The overlap proportions of male home-ranges were greatest in experimental enclosures than in control enclosures, in both the overlap types (male/male, males/females). The intra- (females/females) and inter-sexual (females/males) overlap proportions of female home-ranges were independent of treatment. In C. musculinus, at the beginning of the breeding period and in absence of adult males, juvenile males increase their home-range size and therefore the degree of inter- and intra-sexual home-range overlap as a mechanism for enlarging the number of receptive females that they encounter.

    This study investigated gross efficiency changes in a group of 60 adult males (mean age 39.2 +/- 1.2 years) resulting from endurance training and age-related responses to such training in sub-groups (each n = 20) of younger (30.7 +/- 0.7 years), intermediate (38.3 +/- 0.5 years) and older (48.6 +/- 1.1 years) subjects. Gross efficiency (%) was calculated from work output, oxygen consumption and RER energy equivalents following 10 min standard cycle ergometry exercise at 100 W and 50 rev min-1. Measurements were made at pre-, mid- and post-8 months of training, which involved progressive walking/jogging activities designed to enhance endurance capacity. In the total group, VO2 decreased pre- to post-training from 2.15 +/- 0.02 to 1.93 +/- 0.01 1 min-1 (P less than 0.01). In the sub-groups, both the younger and older subjects showed a significantly reduced VO2, from 2.17 +/- 0.01 to 1.98 +/- 0.04 1 min-1 and 2.05 +/- 0.08 to 1.86 +/- 0.03 1 min-1 respectively (P less than 0.05), but no significant changes were noted at mid-training. In the intermediate age subjects, while there were trends towards a reduced VO2, none was significant. The ANOVA revealed increased mean gross efficiency in the total group from pre- (14.3 +/- 0.1%) to post- (15.5 +/- 0.2%) (P less than 0.05) but not at mid-training (14.8 +/- 0.2%). While similar trends were observed in the sub-groups, gross efficiency increases were not significant, although changes in gross efficiency were reflected in VO2. The findings suggest that during standardized exercise, oxygen cost may be reduced and gross efficiency increased in adult males following endurance training and that such changes may take place over a variety of age ranges.

    The aim of this work was to study the effects of cyclosporine (CsA), tacrolimus (FK-506), and rapamycin (RAPA) on bone mass, femoral microstructure, femoral biomechanical properties, and bone remodeling in healthy adult male rats. Forty-eight 5-month-old male Wistar rats were used. CsA (2 mg/kg/day), FK-506 (3 mg/kg/day), RAPA (1.25 mg/kg/day), or water (0.5 ml/rat/day, control group) were administered orally for 3 months. After sacrifice, mean values of immunosuppressants in blood were: CsA (670.4 ng/ml), FK-506 (19.2 ng/ml), and RAPA (4.8 ng/ml). Levels of biochemical parameters were normal in all groups. Femoral BMD was decreased in FK-506 and RAPA groups and lumbar BMD in FK-506 group. Trabecular volume fraction (BV/TV) decreased only in FK-506 group. RAPA and CsA affected femoral cortical structure, but FK-506 did not. FK-506 produced an increase in bone remodeling, and CsA a decrease. FK-506 group showed a decrease in biomechanical parameters relative to all groups. RAPA group showed a decrease in ultimate stress vs control group, and CsA group presented an increase in biomechanical parameters versus control group. We found that administration of both RAPA and FK-506 as monotherapy for healthy rats produced osteopenia. CsA treatment only produces slight damages in the cortical zone of the femur.

    Numerous studies have shown sex and/or estrous cycle differences in the acoustic startle reflex (ASR) and its prepulse inhibition (PPI) in humans and animals. However, few have examined the effects of hormone manipulations on these behaviors. This study paired gonadectomy (GDX) in adult male rats with testing for ASR and PPI at 2, 4, 9, 16, 23, 30 and 37 days after surgery. Initial studies of control, GDX and GDX rats given testosterone propionate revealed no group differences in PPI, but did reveal phasic facilitation of the ASR in GDX rats that was greatest on the first and final testing sessions and that was attenuated by testosterone. A second study addressing roles for estrogen and androgen signaling tested new control and GDX rats along with GDX rats given estradiol or the non-aromatizable androgen, 5-alpha-dihydrotestosterone and revealed no group differences in PPI, and increases in ASR in GDX rats that were largest during the first and final testing sessions and that were attenuated by both hormone replacements. However, while responses in GDX rats given testosterone were similar to those of controls, ASR in estradiol- and to a lesser extent in dihydrotestosterone-treated GDX rats were typically lower than in controls. This may suggest that hormone modulation of the ASR requires synergistic estrogen and androgen actions. In the male brain where this can be achieved by local steroid metabolism, the enzymes responsible, e.g., aromatase, could help identify loci in the startle circuitry that may be especially relevant for the hormone modulation observed.

    As measured with the Psychopathy Checklist-Revised (PCL-R), psychopathy is a dimensional construct underpinned by 4 correlated factors: Interpersonal, Affective, Lifestyle, and Antisocial. Theorists and clinicians (e.g., Karpman and Arieti) have posited 2 variants of "primary" or "true" psychopathy, both distinct from so-called "secondary" or "pseudopsychopathy." We used latent profile analysis to determine if homogeneous classes exist within a sample of 1,451 male offenders with high PCL-R scores (≥ 27). The 4 PCL-R factors were the dependent variables for clustering. A solution with 3 latent classes showed a better fit to the data than did a unitary model without latent classes. Tentative labels for the latent classes are Manipulative (Latent Class 1 [LC1]), Aggressive (Latent Class 2 [LC2]), and Sociopathic (Latent Class 3 [LC3]). The latter class represented an antisocial group that lacked the emotional detachment observed in the other 2 groups. We propose that LC1 and LC2 reflect phenotypic variations on a theme of the traditional construct of psychopathy, and that LC3 is consistent with conceptions of antisocial personality disorder and sociopathy. Replication and external classification with an independent data set of 497 adult male offenders again yielded clearly separable clusters, as well as meaningful differences or trends among latent classes on education, intelligence, symptoms of antisocial personality disorder, and self-reported psychopathic traits and negative affect. The conceptualization of psychopathy in terms of manipulative and aggressive variants is consistent with clinical theory and is empirically grounded.

    Attention deficit hyperactivity disorder (ADHD) is a pervasive psychiatric disorder that affects both children and adults. Adult male and female patients with ADHD are differentially affected, but few studies have explored the differences. The purpose of this study was to quantify differences between adult male and female patients with ADHD based on neuroimaging and connectivity analysis. Resting-state functional magnetic resonance imaging scans were obtained and preprocessed in 82 patients. Group-wise differences between male and female patients were quantified using degree centrality for different brain regions. The medial-, middle-, and inferior-frontal gyrus, superior parietal lobule, precuneus, supramarginal gyrus, superior- and middle-temporal gyrus, middle occipital gyrus, and cuneus were identified as regions with significant group-wise differences. The identified regions were correlated with clinical scores reflecting depression and anxiety and significant correlations were found. Adult ADHD patients exhibit different levels of depression and anxiety depending on sex, and our study provides insight into how changes in brain circuitry might differentially impact male and female ADHD patients.

    Female-to-male trans masculine adults who have sex with cisgender (non-transgender) males (TMSM) represent an understudied population in relation to HIV/STI risk. This study examined the role of syndemic conditions and social gender affirmation processes (living full-time in one’s identified gender) in potentiating sexual risk among TMSM adults in Massachusetts. Cross-sectional data were restricted to TMSM who reported lifetime sexual behaviour with a cisgender male (n = 173; mean age = 29.4, SD = 9.6; 18.5% people of colour; 93.1% non-heterosexual identity; 56.1% hormones/surgery). Sexual risk outcomes were: lifetime STI diagnoses, three or more past-6-month sexual partners, and condomless anal/vaginal sex at last encounter with a cisgender male. Age- and survey mode-adjusted logistic regression models regressed sexual risk outcomes on the main effect of syndemics (six indicators summed: binge drinking, substance use, depression, anxiety, childhood abuse, intimate partner violence), followed by the interaction of syndemics and social gender affirmation. Syndemics were associated with increased odds of all sexual risk indicators (adjusted odds ratios (aORs) = 1.32–1.55; p < 0.0001). Social gender affirmation moderated the association between syndemics and condomless anal/vaginal sex at last encounter with a cisgender male (p < 0.0001). Syndemics were associated with sexual risk in TMSM who had socially affirmed their gender (aOR = 1.79; 95% CI = 1.42–2.25; p < 0.001), but not among those TMSM who had not (aOR = 0.86; 95% CI = 0.63–1.19; p = 0.37). Findings suggest that syndemic pathways to sexual risk are similar for TMSM who have socially gender affirmed as for cisgender MSM. Integration of syndemics and gender affirmation frameworks is recommended in interventions to address TMSM sexual risk. PMID:26384946

    With the continued rise in feline obesity, novel weight management strategies are needed. To date, strategies aimed at altering physical activity, an important factor in weight maintenance, have been lacking. Photoperiod is known to cause physiological changes in seasonal mammals, including changes in body weight (BW) and reproductive status. Thus, our objective was to determine the effect of increased photoperiod (longer days) on voluntary physical activity levels, resting metabolic rate (RMR), food intake required to maintain BW, and fasting serum leptin and ghrelin concentrations in adult cats. Eleven healthy, adult, neutered, male domestic shorthair cats were used in a randomized crossover design study. During two 12-week periods, cats were exposed to either a short-day (SD) photoperiod of 8 h light: 16 h dark or a long-day (LD) photoperiod of 16 h light: 8 h dark. Cats were fed a commercial diet to maintain baseline BW. In addition to daily food intake and twice-weekly BW, RMR (via indirect calorimetry), body composition [via dual-energy X-ray absorptiometry (DEXA)] and physical activity (via Actical activity monitors) were measured at week 0 and 12 of each period. Fasting serum leptin and ghrelin concentrations were measured at week 0, 6 and 12 of each period. Average hourly physical activity was greater (p = 0.008) in LD vs. SD cats (3770 vs. 3129 activity counts/h), which was primarily due to increased (p < 0.001) dark period activity (1188 vs. 710 activity counts/h). This corresponded to higher (p < 0.0001) daily metabolizable energy intake (mean over 12-week period: 196 vs. 187 kcal/day), and increased (p = 0.048) RMR in LD cats (9.02 vs. 8.37 kcal/h). Body composition, serum leptin and serum ghrelin were not altered by photoperiod. More research is needed to determine potential mechanisms by which these physiological changes occurred and how they may apply to weight management strategies.

    Background Worldwide, systemic arterial hypertension is a leading cause of death and non-communicable cardiovascular disease. A major factor contributing to this disease is a sedentary lifestyle. However, physical exercise, such as martial arts, may be an option for blood pressure (BP) control. The magnitude of post-exercise hypotension is associated with a prolonged decrease in BP in normotensive and hypertensive individuals. Objectives The present study aimed to verify the effects of a Contact Karate (CK) session on BP responses during a post-exercise recovery period in young adults. Patients and Methods Thirty-two male CK athletes volunteered (28.2 ± 6.7 years; 77.0 ± 5.7 kg; and 176.0 ± 4.7 cm) and underwent one CK session (50 minutes) and a control session in which no exercise was performed and the individuals remain seated during the whole time. BP was measured during rest (before sessions), as well as on the 15th, 30th, 45th, and 60th minutes of the post-exercise recovery. Results The systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP) were significantly lower at the post-exercise period compared to pre-exercise rest (P < 0.05), with the largest reductions being observed at the 60th minutes of recovery [SBP (rest: 125.9 ± 4.7 vs. 60th minutes of recovery: 111.7 ± 5.4 mmHg); DBP (rest: 78.8 ± .7 vs. 60th minutes of recovery: 69.8 ± 2.7 mmHg)] and at the same periods of post-exercise recovery of the control session. Conclusions A single CK session can promote a decrease in BP for at least 60 minutes after performing this type of exercise in young adults. PMID:27826399

    Epidemiological investigations indicate that osteoarthritis is associated with intrauterine growth retardation (IUGR) and abnormal cholesterol metabolism. Our previous studies showed that prenatal caffeine exposure (PCE) induced chondrogenesis retardation in IUGR offspring rats. The current study sought to investigate the effects of PCE on male IUGR offspring rats’ articular cartilage, and the mechanisms associated with abnormal cholesterol metabolism. Based on the results from both male fetal and adult fed a high-fat diet (HFD) studies of rats that experienced PCE (120 mg/kg.d), the results showed a poor quality of articular cartilage and cholesterol accumulation in the adult PCE group. Meanwhile, the serum total cholesterol and low-density lipoprotein-cholesterol concentrations were increased in adult PCE offspring. We also observed lower expression of insulin-like growth factor1 (IGF1) and impaired cholesterol efflux in adult articular cartilage. Furthermore, the expression of cartilage functional genes, components of the IGF1 signaling pathway and cholesterol efflux pathway related genes were decreased in PCE fetal cartilage. In conclusion, PCE induced a poor quality of articular cartilage in male adult offspring fed a HFD. This finding was shown to be due to cholesterol accumulation in the cartilage, which may have resulted from intrauterine reduced activity of the IGF1 signaling pathway. PMID:26639318

    The aim of this study was to characterize changes in physiological and biochemical parameters during electroejaculation (EE) under general anaesthesia in adult and yearling pampas deer males (Ozotoceros bezoarticus). The relation between heart rate, pulse rate, respiratory rate and oximetry with EE voltages was studied. The changes in cortisol, alkaline phosphatase, creatine kinase, aspartate aminotransferase and rectal temperature were determined before and after electroejaculation (BEE and AEE). Heart rate and pulse rate values increased during EE, with a greater increase in heart rate in adults (p < 0.01). Respiratory rate and SpO(2) were not affected by EE or category. The rectal temperature decreased in adults and yearlings during EE (p = 0.0001). Alkaline phosphatase, creatine kinase and aspartate aminotransferase concentrations increased AEE (p < 0.001, p < 0.01 and p < 0.05, respectively). Alkaline phosphatase and creatine kinase concentrations were greater in young than in adult males (p < 0.05). In conclusion, the EE under general anaesthesia in the pampas deer provoked increases in heart and pulse rates, as well as in creatine kinase, aspartate aminotransferase and alkaline phosphatase concentrations, and a decrease in rectal temperature in both categories. Oximetry values were especially low during the procedure. Heart rate increase was greater in adult males, and alkaline phosphatase and creatine kinase concentrations were greater in yearlings.

    Phthalic acid esters (PAEs) are a class of synthetic industrial chemicals commonly found in the aquatic environment worldwide. PAEs have been recognised as anti-androgens in male mammals but little is known about their endocrine disrupting effects in fish. This study investigated the effects of 7-day exposures to nominal (measured) concentrations of 125 (62), 250 (140), 500 (230) and 1,000 (383) μg/L of di-n-butyl phthalate (DnBP) on the biomarkers of reproduction in adult male Murray River rainbowfish (Melanotaenia fluviatilis) using molecular, biochemical and histological endpoints. None of the tested concentrations of DnBP had any effect on survival or the vital body indices of the fish. The sizes of spermatogonia, Type A and B spermatocytes and spermatids were significantly smaller relative to the controls after treatment with DnBP. This was accompanied by a significant increase in the proportion of spermatogonia in fish treated with 250-1,000 μg/L of DnBP in comparison to the unexposed fish. At the end of the exposure period, the expressions of the transcripts for the androgen receptors α and β were significantly elevated in the livers of the fish treated with 500 and 1,000 μg/L of DnBP. In addition, there was also an increase in the circulating concentrations of vitellogenin in the plasma in the higher treatment groups. An induction in the activity of aromatase was noted in the brains of 1,000 μg/L DnBP-treated fish. This was accompanied by an increase in the hepatic expression of the genes (here and later, whenever the phrase gene expression is used as a synonym for gene transcription although it is acknowledged that it is also regulated, e.g., by translation, mRNA stability and protein stability) encoding for the oestrogen receptors α and β and choriogenin L.

The densities were similar to the high density lipoprotein (HDL) and to two very high density lipoproteins (VHDL) isolated from a pool of adult male and female insects fasted during twelve days. The relative distribution and composition of the three lipoproteins were studied. The fatty acids were mainly carried by the 1.3 and 1.2 diacylglycerols of high density lipoprotein. Triacylglycerols were minor components. Similarly to fasted insects, the main fatty acids were oleic and palmitic. Linoleic was also present. Very high density lipoproteins (VHDL-II) (d 1.25-1.26) were found in the haemolymph of male insects. The relative distribution of HDL and VHDL on fed and fasted insects was different.

    Environmental cues can act to initiate alternative developmental trajectories that result in different adult phenotypes, including behavioral phenotypes. The developmental period when an organism is sensitive to the cue is often described as a critical period. Here we investigated the critical period for temperature-sensitive courtship rate plasticity in the butterfly Bicyclus anynana. We performed a series of temperature-shift experiments in which larvae, pupae, or adults were shifted for blocks of time from one temperature to an alternative temperature, and then we quantified the courtship rate exhibited by adult males. We discovered that the critical period begins during pupal development and extends into adulthood, but temperature experienced during larval development does not affect male courtship rate. This finding allows us to develop hypotheses that address how developmental and physiological factors may have influenced the evolution of behavioral plasticity in this species. PMID:23717531

    Tonic immobility (TI) is a set of involuntary motor responses elicited under conditions of extreme fear and perceived inescapability, and it is one type of peritraumatic distress reported by survivors of childhood sexual abuse (CSA). Experiencing TI during CSA is associated with increased risk for developing symptoms of posttraumatic stress disorder (PTSD), although less is known about relations between TI and other established risk factors for PTSD. We investigated posttraumatic cognitions as a potential mediator of the relations between peritraumatic fear, perceptions of inescapability, TI, and PTSD symptoms. Specifically, we tested posttraumatic negative beliefs about the self, the world, and self-blame as pathways that might increase risk for PTSD symptoms in CSA survivors who had experienced TI. Forty-six women with a history of unwanted childhood sexual contact completed questionnaires measuring peritraumatic tonic immobility, posttraumatic cognitions, and current posttraumatic stress symptoms. Negative beliefs about the self independently mediated the relation between peritraumatic perceptions of inescapability and PTSD symptoms, but the data did not support similar path model for the physical symptoms of TI and PTSD. We discuss ways in which treatment of survivors and future research on CSA can benefit from attention to the impact of peritraumatic distress on posttraumatic beliefs. PMID:26701284

    The concentrations of 16 phthalates in 164 commercial Chinese rice wines (CRW) were detected by GC-MS, and consumption data on CRW in different packaging types was investigated from 634 adult males in Shanghai using a food frequency questionnaire. Based on the principles of probabilistic modelling and cumulative risk assessment, the exposure and health risk of phthalates from CRW to adult males in Shanghai was evaluated. DMP, DEP, DIBP, DnBP, BBP, and DEHP were detected in the samples, the range of detection frequency of individual phthalates varied from 6.10% for BBP to 15.24% for DIBP, and the detected concentrations were 51.06-200.34 ng/mL. All the respondents consumed CRW, 90.69% of them consumed CRW 0.01-49.9 mL/d, the minimum value of the average daily intake of CRW was 6.25 mL/d, the median was 13.72 mL/d and the maximum was 300 mL/d. The median exposure level of the 6 detected Phthalates to adult males in Shanghai were 6.58-7.10 ng/(d•kg), and the maximum exposure level were 137.38-540.47 ng/(d•kg). The cumulative exposure health risk index (HI) based on the median and maximum exposure level of the 6 Phthalates (DMP, DEP, DIBP, DnBP, BBP, and DEHP) were 0.001147 and 0.063396, both were far less than 1. In conclusion, CRW were generally consumed by the adult males in Shanghai, although multiple phthalates were detected in commercial CRW, health risk of such exposure levels from commercial CRW to the target adult males in Shanghai was very low.

  20. Juvenile Rank Can Predict Male-Typical Adult Mating Behavior in Female Sheep Treated Prenatally with Testosterone1

    Previous research with female sheep indicates that exposure to excess testosterone for 60 days (from Gestational Days 30–90 of the 147-day gestation) leads to virilized genitalia, severe neuroendocrine deficits, as well as masculinization and defeminization of sexual behavior (T60 females). In contrast, 30 days of testosterone exposure (Gestational Days 60–90) produce animals with female-typical genitalia, less severe neuroendocrine alterations, and variable gender patterns of sexual behavior (T30 females). Variation in adult sexual behavior of male ungulates is influenced by early social experience, but this has never been tested in females. Here we investigate the influence of rank in the dominance hierarchy on the expression of adult sexual behavior in females. Specifically, we hypothesized that juvenile rank would predict the amount of male- and female-typical mating behavior exhibited by adult female sheep. This hypothesis was tested in two treatment groups and their controls (group 1: T60 females; group 2: T30 females). Dominance hierarchies were determined by observing competition over resources. Both groups of prenatal testosterone-treated females were higher ranking than controls (T60: P = 0.05; T30: P < 0.01). During the breeding season, both T60 and T30 females exhibited more male-typical mating behavior than did controls; however, the T30 animals also exhibited female-typical behavior. For the T60 group, prenatal treatment, not juvenile rank, best predicted male-typical sex behavior (P = 0.007), while juvenile rank better predicted male mating behavior for the T30 group (P = 0.006). Rank did not predict female mating behavior in the hormone-treated or control ewes. We conclude that the effect of prenatal testosterone exposure on adult male-specific but not female-specific mating behavior is modulated by juvenile social experiences. PMID:19122184

    There are human reproduction concerns associated with extensive use of bisphenol A (BPA)-containing plastic and, in particular, the leaching of BPA into food and beverages. In this context, it remains unclear whether and how exposure to BPA interferes with the developmental organization and adult activation of male sexual behavior by testosterone. We evaluated the developmental and adult exposure to oral BPA at doses equivalent to the no-observed-adverse-effect-level (5 mg/kg body weight per day) and tolerable daily intake (TDI) (50 μg/kg body weight per day) on mouse sexual behavior and the potential mechanisms underlying BPA effects. Adult exposure to BPA reduced sexual motivation and performance at TDI dose only. Exposed males took longer to initiate mating and reach ejaculation despite normal olfactory chemoinvestigation. This deficiency was not restored by sexual experience and was associated with unchanged circulating levels of testosterone. By contrast, developmental exposure to BPA at TDI or no-observed-adverse-effect-level dose did not reduce sexual behavior or alter the neuroanatomical organization of the preoptic area. Disrupting the neural androgen receptor resulted in behavioral and neuroanatomical effects similar to those induced by adult exposure to TDI dose. Moreover, adult exposure of mutant males to BPA at TDI dose did not trigger additional alteration of sexual behavior, suggesting that BPA and neural androgen receptor mutation share a common mechanism of action. This shows, for the first time, that the neural circuitry underlying male sexual behavior is vulnerable to chronic adult exposure to low dose of BPA and suggests that BPA could act in vivo as an antiandrogenic compound.

    This paper presents a large-scale study of subglottal resonances (SGRs) (the resonant frequencies of the tracheo-bronchial tree) and their relations to various acoustical and physiological characteristics of speakers. The paper presents data from a corpus of simultaneous microphone and accelerometer recordings of consonant-vowel-consonant (CVC) words embedded in a carrier phrase spoken by 25 male and 25 female native speakers of American English ranging in age from 18 to 24 yr. The corpus contains 17 500 utterances of 14 American English monophthongs, diphthongs, and the rhotic approximant [ɹ] in various CVC contexts. Only monophthongs are analyzed in this paper. Speaker height and age were also recorded. Findings include (1) normative data on the frequency distribution of SGRs for young adults, (2) the dependence of SGRs on height, (3) the lack of a correlation between SGRs and formants or the fundamental frequency, (4) a poor correlation of the first SGR with the second and third SGRs but a strong correlation between the second and third SGRs, and (5) a significant effect of vowel category on SGR frequencies, although this effect is smaller than the measurement standard deviations and therefore negligible for practical purposes.

    Hypersexuality, or extreme normophilic sexual urges and behaviors, is a controversial construct that was recently considered as a candidate disorder for the DSM-5 and was rejected. It was also rejected for inclusion in Section III (Conditions for Further Study). Nonetheless, it has been found to be an important predictor of recidivism among sex offenders, and it continues to be discussed widely in the literature. In the present study, we investigated the developmental roots of this construct in a sample of 529 adult male sexual offenders, who were administered the Multidimensional Assessment of Sex and Aggression. Physical, psychological, and sexual abuse experiences were estimated using several scales of early development. Psychological abuse in childhood and adolescence, especially by a father, was found to be the most prominent predictor of subsequent hypersexual thoughts and behaviors. The accumulation of abuse types, however, was also associated with a monotonic increase in the latent trait of hypersexuality. The consequences of these results for conceptualizations of the construct are discussed.

    It is known that pica, the consumption of non-nutritive substances such as kaolin, can be induced by administration of toxins or emetic agents in rats. In the present study, we examined the effects of intraperitoneal (i.p.) administration of cyclophosphamide on pica behavior and on the concentration of 5-hydroxyindoleacetic acids (5HIAA) in cerebrospinal fluid (CSF) in the following five strains of adult male rats: Sprague Dawley (SD), Wistar, Fischer 344 (F344), Wistar-Imamichi (WI) and Long Evans (LE). Cyclophosphamide (25 mg or 50 mg/kg) was injected (i.p.) into the rats and kaolin and food intake were measured at 24 hr after injection. The animals were anesthetized with urethane (1 g/kg) at 3 hr after injection of cyclophosphamide, and CSF was collected from the cisterna magna. WI and LE rats clearly showed pica behavior as compared with the other strains. In LE rats, the concentration of 5HIAA in CSF also increased in a dose-dependent manner of cyclophosphamide. The pretreatment with ondansetron (5-HT(3) antagonist) restored both changes (kaolin consumption and 5HIAA levels) induced by cyclophosphamide. These results suggest that the LE rat is sensitive to cyclophosphamide, that pica induced by cyclophosphamide mimics many aspects of emesis including the serotonergic response in the central nervous system and that use of the pica model would be a practical method for evaluating the effects of antiemetic drugs in addition to the mechanism of emesis.

    While there is growing evidence that suffering physical abuse during childhood is subsequently associated with psychopathic traits in both juvenile and adult offenders, there is considerably less research on whether exposure to domestic violence as a witness, rather than as a direct victim, influences the subsequent presentation of psychopathic traits in adulthood. Accordingly, the current study examined the relationship between witnessing domestic violence during childhood (i.e., witnessing, hearing, or intervening in abuse against a parent/sibling) and psychopathic traits in adulthood in a sample of n = 127 incarcerated male offenders. As predicted, witnessing domestic violence was significantly associated with overall level of psychopathy, with a particularly strong relationship to the interpersonal/affective features of psychopathy. Importantly, this relationship held when controlling for the experience of domestic violence as a direct victim. These results add to the growing body of literature linking adverse and traumatic events during childhood with psychopathic traits later in life, and suggest that domestic violence exposure may be one factor contributing to the manipulative, interpersonal style exhibited by individuals high in psychopathy.

    Adult, male Sprague-Dawley rats received 100 mg/kg Ginkgo biloba extract (GBE) intraperitoneally for 30 days. GBE reduced overall activity and decreased sensitivity to light in the open field maze. The rats were also less responsive to noxious stimuli after 13 days of treatment with GBE. After the last injection, all subjects were trained on a delayed-spatial alternation task. Subsequent to acquisition of the spatial task, the rats received either sham operations and saline or bilateral frontal cortex lesions treated with either saline or GBE. Thirty additional days of treatment began on the day of injury, and open field behavior, analgesia, and metabolic activity measurements were again measured. The rats with lesions treated with saline were more active than their GBE-treated counterparts and sham controls but there were no differences in response to illumination or noxious stimuli. Retention of the delayed-spatial alternation indicated that rats with lesions treated with GBE were less impaired than brain-injured subjects receiving saline treatment. Histological examination showed that GBE reduced the extent of brain swelling in response to the injury.

    Gambling behavior is not a unique behavior. There are certain differences in behavior, gambling habits, gambling beliefs, and their reflection in psychosocial life. We have compared three groups of adult male gamblers—sports gamblers (n = 41), machine gamblers (n = 36), and poker gamblers (n = 35)—in regard to measures of personal status and legal-social characteristics. We found no difference between groups in terms of the length of gambling behavior, personal status, or age. We found no legal difference between groups in terms of the number of court cases for debt, stealing, or family court cases. In terms of economic circumstances, sports gamblers suffered more losses than the other groups (p < 0.0001). There were higher rates of bankruptcy among sports gamblers compared with machine gamblers (p < 0.01). Sports gamblers were more likely to borrow money from the black market compared with the other groups (p < 0.01). In terms of mental health, sports and machine gamblers had more suicidal thoughts and gestures than poker gamblers (p < 0.05), whereas the rate of suicide attempts was higher in machine gamblers compared with poker players (p < 0.05). Our results indicated higher vulnerability in sports gamblers in terms of economic problems compared with the other groups, whereas machine gamblers had vulnerability to suicidal thoughts and suicidal attempts compared with poker gamblers.

    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.

    Chronic ethanol consumption is often accompanied by numerous cognitive deficits and may lead to long-lasting impairments in spatial learning and memory. The aim of the present study was to evaluate the therapeutic potential of regular treadmill exercise on hippocampal-dependent memory in ethanol-treated rats. Spatial memory was tested in a Morris Water Maze task. Adult male Wistar rats were exposed to ethanol (4 g/kg, 20% v/v for 4 weeks) and effects of three exercise protocols (pre-ethanol, post-ethanol and pre-to-post-ethanol treatment) were examined. Results showed that ethanol exposure resulted in longer escape latencies during the acquisition phase of the Morris Water Maze task. Moreover, all three exercise protocols significantly decreased the latency to locate the hidden platform. During the probe trial, ethanol led to decreased time spent in the target quadrant. In contrast, performance on the probe trial was significantly better in the rats that had done the post- and pre-to-post-ethanol, but not pre-ethanol, exercises. These findings suggest that treadmill running can attenuate the adverse effects of chronic ethanol exposure on spatial memory, and may serve as a non-pharmacological alcohol abuse treatment.

    Nicotine has been shown to enhance the motivational properties of non-nicotine stimuli. This reinforcement-enhancing property of nicotine has the potential to promote the use of other illicit substances as well as maladaptive patterns of food intake. Therefore, the current study aimed to examine whether nicotine enhances preference for contexts paired with cocaine or sucrose utilizing a place conditioning procedure. Separate groups of adult male rats were administered sucrose or cocaine in one of two compartments of a standard CPP chamber on four consecutive days. Preference was then assessed following no injection, a single subcutaneous (s.c.) injection of nicotine, and a s.c. saline injection. The animals preferred the chamber paired with either sucrose or cocaine, as evident from an increased time spent in the paired chamber compared to baseline. Nicotine further increased the time spent in the sucrose- or cocaine-paired chamber, consistent with a reinforcement-enhancement effect. Previous results demonstrate an interaction between nicotine and intake of other drugs or food. The present findings provide an additional mechanism that may underlie these effects and which may have implications for drug dependence and obesity.

    This work was undertaken to evaluate the possible effects of cadmium exposure on 24 h changes of gamma-aminobutyric acid (GABA) and taurine median eminence and pituitary contents. Also the possible alterations of the regulatory mechanisms of GABA and taurine on prolactin secretion were evaluated. Adult male rats were given cadmium at a dose of 25 mg/l of cadmium chloride in the drinking water for 30 days. Control age-matched rats received cadmium free water. Metal exposure induced the appearance of a maximal value of prolactin at 08:00 h. In median eminence, cadmium abolished the GABA and taurine maximal values and decreased GABA and taurine mean levels. In the anterior pituitary, cadmium treatment phase advanced 12 h the peak observed in controls at 00:00 h for both amino acids. There was a positive correlation between GABA and taurine contents in median eminence and the anterior pituitary in both control and cadmium-exposed animals. However, the correlation between GABA or/and taurine with prolactin levels disappeared in cadmium-exposed animals. These results suggest that cadmium exposure affects GABA and taurine daily pattern in the median eminence and anterior pituitary, and those changes explain, at least in part, the modification in the regulatory pattern of prolactin secretion.

    The present study was conducted to investigate the possible effects of cadmium exposure on the daily pattern of aspartate, glutamate, glutamine, gamma-aminobutyric acid (GABA) and taurine levels in the mediobasal hypothalamus of adult male rats. For this purpose, animals were treated with cadmium at two different exposure doses (25 and 50 mg l(-1) of cadmium chloride, CdCl(2)) in the drinking water for 30 days. Control age-matched rats received CdCl(2)-free water. After the treatment, rats were killed at six different time intervals throughout a 24 h cycle. CdCl(2) exposure modified the amino acid daily pattern, as it decreased aspartate, glutamate, GABA and taurine levels at 12:00 h with both exposure doses employed. In addition, the treatment with 25 mg l(-1) of CdCl(2) induced the appearance of minimal values at 16:00 h and maximal values between 04:00 and 08:00 h for glutamate, and a peak of glutamine content at 20:00 h. The heavy metal also decreased GABA medium levels around the clock in the mediobasal hypothalamus. However, CdCl(2) did not alter the metabolic correlation between glutamate, aspartate, glutamine and GABA observed in control animals. These results suggest that CdCl(2) induced several alterations in aspartate, glutamate, glutamine, GABA and taurine daily pattern in the mediobasal hypothalamus and those changes may be related to alterations in hypothalamic function.

    2014-08-01

    Exposure to stress during childhood and adolescence increases vulnerability to developing several psychopathologies in adulthood and alters the activity of the hypothalamic-pituitary-adrenal (HPA) axis, the prototypical stress system. Rodent models of juvenile stress appear to support this hypothesis because juvenile stress can result in reduced activity/exploration and enhanced anxiety, although results are not always consistent. Moreover, an in-depth characterization of changes in the HPA axis is lacking. In the present study, the long-lasting effects of juvenile stress on adult behavior and HPA function were evaluated in male rats. The juvenile stress consisted of a combination of stressors (cat odor, forced swim and footshock) during postnatal days 23-28. Juvenile stress reduced the maximum amplitude of the adrenocorticotropic hormone (ACTH) levels (reduced peak at lights off), without affecting the circadian corticosterone rhythm, but other aspects of the HPA function (negative glucocorticoid feedback, responsiveness to further stressors and brain gene expression of corticotrophin-releasing hormone and corticosteroid receptors) remained unaltered. The behavioral effects of juvenile stress itself at adulthood were modest (decreased activity in the circular corridor) with no evidence of enhanced anxiety. Imposition of an acute severe stressor (immobilization on boards, IMO) did not increase anxiety in control animals, as evaluated one week later in the elevated-plus maze (EPM), but it potentiated the acoustic startle response (ASR). However, acute IMO did enhance anxiety in the EPM, in juvenile stressed rats, thereby suggesting that juvenile stress sensitizes rats to the effects of additional stressors.

    Early life stress, such as child abuse or neglect, is a risk factor for the development of psychopathologies characterized by abnormal social and emotional behaviors. In rodents, long-lasting changes in stress coping and emotional behavior can be induced by separating pups from their mother. We used maternal separation (MS; 3h daily on postnatal days 1-14) to test whether early life stress alters acquisition and extinction of social fear in adult male mice as studied in a specific model of social fear, i.e., in the social fear conditioning paradigm. We show that MS facilitated extinction of social fear without altering acquisition or expression of social fear. This facilitatory effect of MS on social fear extinction was not due to improved social learning and memory abilities or to increased social interest, as MS rather impaired social memory in the social discrimination test and did not alter social preference in the social preference-avoidance test. In contrast, MS did not alter acquisition and extinction of non-social, cued fear, or non-social memory as assessed in the object discrimination test and non-social anxiety as assessed in the elevated plus-maze. These results suggest that a social stress like MS in early life may improve coping with and recovery from a traumatic social experience in adulthood in mice.

    The purpose of this study is to investigate the effects of adult male circumcision on premature ejaculation (PE). Therefore, between December 2009 and March 2014, a total of 575 circumcised men and 623 uncircumcised men (control group) were evaluated. Detailed evaluations (including circumcision and control groups) on PE were conducted before circumcision and at the 3-, 6-, 9-, and 12-month follow-up visits after circumcision. Self-estimated intravaginal ejaculatory latency time (IELT), Patient-Reported Outcome measures, and 5-item version of the International Index of Erectile Function were used to measure the ejaculatory and erectile function for all subjects. The results showed that, during the one-year follow-up, men after circumcision experienced higher IELT and better scores of control over ejaculation, satisfaction with sexual intercourse, and severity of PE than men before circumcision (P < 0.001 for all). Similarly, when compared with the control group, the circumcised men reported significantly improved IELT, control over ejaculation, and satisfaction with sexual intercourse (P < 0.001 for all). These findings suggested that circumcision might have positive effects on IELT, ejaculatory control, sexual satisfaction, and PE severity. In addition, circumcision was significantly associated with the development of PE.

    The purpose of this study was to measure the effect of action video gaming on central elements of visual attention using Bundesen's (1990) Theory of Visual Attention. To examine the cognitive impact of action video gaming, we tested basic functions of visual attention in 42 young male adults. Participants were divided into three groups depending on the amount of time spent playing action video games: non-players (<2h/month, N=12), casual players (4-8h/month, N=10), and experienced players (>15h/month, N=20). All participants were tested in three tasks which tap central functions of visual attention and short-term memory: a test based on the Theory of Visual Attention (TVA), an enumeration test and finally the Attentional Network Test (ANT). The results show that action video gaming does not seem to impact the capacity of visual short-term memory. However, playing action video games does seem to improve the encoding speed of visual information into visual short-term memory and the improvement does seem to depend on the time devoted to gaming. This suggests that intense action video gaming improves basic attentional functioning and that this improvement generalizes into other activities. The implications of these findings for cognitive rehabilitation training are discussed.

    Pharmaceuticals and personal care products (PPCPs) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world.

    Pharmaceuticals and personal care products (PPCPs) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world. A major source of these compounds is incomplete metabolism in humans and subsequent excretion in human waste, resulting in discharge into surface waters by wastewater treatment plant (WWTP) effluent. One pharmaceutical found in particularly high abundance in recent WWTP effluent and surface water studies is metformin, one of the world's most widely prescribed antidiabetic drugs.

    The present study investigated the interaction between histamine and opioid systems on water intake in adult male rats. Intracerebroventricular (i.c.v.) injections were carried out in all experiments. Water intake was measured 1 h after drug injections. Administration of histamine (40-80 microg/rat) and naloxone (0.5-1 microg/rat) increased, while morphine (2.5 microg/rat), pyrilamine (25-50 microg/rat), the histamine H1 receptor antagonist, and ranitidine (10-20 microg/rat), the histamine H2 receptor antagonist, decreased water intake in isolated rats. Blockade of histamine H1 and H2 receptors attenuated the histamine-induced response. Pyrilamine, but not ranitidine, increased the inhibitory effect induced by morphine. Also, pharmacological blockade of histamine H1 and H2 receptors decreased the naloxone-induced effect on water intake. It is concluded that the histaminergic system may have a close interaction with morphine and naloxone on drinking behavior.

    A maternal high-fat (HF) diet during pregnancy can lead to metabolic compromise, such as insulin resistance in adult offspring. Skeletal muscle mitochondrial dysfunction is one mechanism contributing to metabolic impairments in insulin resistant states. Therefore, the present study aimed to investigate whether mitochondrial dysfunction is evident in metabolically compromised offspring born to HF-fed dams. Sprague-Dawley dams were randomly assigned to receive a purified control diet (CD; 10% kcal from fat) or a high fat diet (HFD; 45% kcal from fat) for 10 days prior to mating, throughout pregnancy and during lactation. From weaning, all male offspring received a standard chow diet and soleus muscle was collected at day 150. Expression of the mitochondrial transcription factors nuclear respiratory factor-1 (NRF1) and mitochondrial transcription factor A (mtTFA) were downregulated in HF offspring. Furthermore, genes encoding the mitochondrial electron transport system (ETS) respiratory complex subunits were suppressed in HF offspring. Moreover, protein expression of the complex I subunit, NDUFB8, was downregulated in HF offspring (36%), which was paralleled by decreased maximal catalytic linked activity of complex I and III (40%). Together, these results indicate that exposure to a maternal HF diet during development may elicit lifelong mitochondrial alterations in offspring skeletal muscle. PMID:27917127

    In order to best cover the possible extent of heights and weights of male adults the construction of 25 whole body 3D models has been undertaken. Such a library is thought to be useful to specify the uncertainties and relevance of dosimetry calculations carried out with models representing individuals of average body heights and weights. Representative 3D models of Caucasian body types are selected in a commercial database according to their height and weight, and 3D models of the skeleton and internal organs are designed using another commercial dataset. A review of the literature enabled one to fix volume or mass target values for the skeleton, soft organs, skin and fat content of the selected individuals. The composition of the remainder tissue is fixed so that the weight of the voxel models equals the weight of the selected individuals. After mesh and NURBS modelling, volume adjustment of the selected body shapes and additional voxel-based work, 25 voxel models with 109 identified organs or tissue are obtained. Radiation transport calculations are carried out with some of the developed models to illustrate potential uses. The following points are discussed throughout this paper: justification of the fixed or obtained models' features regarding available and relevant literature data; workflow and strategy for major modelling steps; advantages and drawbacks of the obtained library as compared with other works. The construction hypotheses are explained and justified in detail since future calculation results obtained with this library will depend on them.

    In this study we evaluated the time dependence in cadmium-nicotine interaction and its effect on motor function, anxiety linked behavioural changes, serum electrolytes, and weight after acute and chronic treatment in adult male mice. Animals were separated randomly into four groups of n = 6 animals each. Treatment was done with nicotine, cadmium, or nicotine-cadmium for 21 days. A fourth group received normal saline for the same duration (control). Average weight was determined at 7-day interval for the acute (D1-D7) and chronic (D7-D21) treatment phases. Similarly, the behavioural tests for exploratory motor function (open field test) and anxiety were evaluated. Serum electrolytes were measured after the chronic phase. Nicotine, cadmium, and nicotine-cadmium treatments caused no significant change in body weight after the acute phase while cadmium-nicotine and cadmium caused a decline in weight after the chronic phase. This suggests the role of cadmium in the weight loss observed in tobacco smoke users. Both nicotine and cadmium raised serum Ca2+ concentration and had no significant effect on K+ ion when compared with the control. In addition, nicotine-cadmium treatment increased bioaccumulation of Cd2+ in the serum which corresponded to a decrease in body weight, motor function, and an increase in anxiety. PMID:26317007

    Aerobic capacity, as indicated by maximal oxygen uptake (VO2 max) has an important role in contrasting the traditional cardiovascular risk factors and preventing cardiovascular morbidity and mortality. It is known that endothelial function, measured as flow-mediated dilation (FMD) of the brachial artery, is strictly linked to atherogenesis and cardiovascular risk. However, the relationship between VO2 max and FMD has not been fully investigated especially in healthy non-obese subjects. This preliminary study cross-sectionally investigated the relationship between VO2 max and FMD in 22 non-obese, healthy sedentary male subjects. Dividing the cohort in two subgroups of 11 subjects each according to the median value of VO2 max, the FMD was significantly lower in the subgroup with lower VO2 max (mean ± sem: 7.1 ± 0.7 vs. 9.5 ± 0.8 %; P = 0.035). Absolute VO2 max (mL min(-1)) was significantly and independently correlated with body fat mass (r = -0.50; P = 0.018) and with FMD (r = 0.44; P = 0.039). This preliminary study suggests that maximal oxygen uptake is independently correlated with endothelial function in healthy non-obese adults. These results are also in agreement with the possibility that improving maximal oxygen uptake may have a favorable effect on endothelial function and vice versa.

  5. Hemispheric differences in dichaptic scanning of verbal and spatial material by adult males and females.

    An experimental design based on the combination of dichaptic presentation associated to the Posner's paradigm was adopted to investigate laterality effects for verbal and spatial non-linguistic stimuli in male and female adult normal subjects. In a grapheme similarity judgment task based on "Name Identity" a right hand/left hemisphere advantage was found. Conversely, laterality effects were neither observed when the task involved "Perceptually Identical" or "Different" letter pairs. In a further experiment, the same methodology was adopted to verify hemispheric effects with spatial non-linguistic material, and a significant advantage for the left hand/right hemisphere was observed. Contrary to many previous studies, no gender or gender x task effects have been detected in both experiments. The present results suggest the existence, also in the tactile domain, of a direct link between input type and the linguistic or non-linguistic processing to which the two hemispheres are devoted. The overall pattern of data seriously hampers Witelson's original hypothesis that letter stimuli presented in the tactile modality are primarily processed as spatial stimuli, and are therefore dependent on the right hemisphere functioning.

  6. Carbachol-Induced Reduction in the Activity of Adult Male Zebra Finch RA Projection Neurons

    Cholinergic mechanism is involved in motor behavior. In songbirds, the robust nucleus of the arcopallium (RA) is a song premotor nucleus in the pallium and receives cholinergic inputs from the basal forebrain. The activity of projection neurons in RA determines song motor behavior. Although many evidences suggest that cholinergic system is implicated in song production, the cholinergic modulation of RA is not clear until now. In the present study, the electrophysiological effects of carbachol, a nonselective cholinergic receptor agonist, were investigated on the RA projection neurons of adult male zebra finches through whole-cell patch-clamp techniques in vitro. Our results show that carbachol produced a significant decrease in the spontaneous and evoked action potential (AP) firing frequency of RA projection neurons, accompanying a hyperpolarization of the membrane potential, an increase in the evoked AP latency, afterhyperpolarization (AHP) peak amplitude, and AHP time to peak, and a decrease in the membrane input resistance, membrane time constant, and membrane capacitance. These results indicate that carbachol reduces the activity of RA projection neurons by hyperpolarizing the resting membrane potential and increasing the AHP and the membrane conductance, suggesting that the cholinergic modulation of RA may play an important role in song production.

    Introduction: This case report describes a human survivor of Balamuthia mandrillaris infection. This is a free-living amoeba that can cause infection with the devastating consequence of near universally fatal encephalitis. We report this case to demonstrate the possibility of recovery. Case presentation: A 26-year-old Hispanic male, a landscape gardener, presented to the hospital in March 2010 with a two month history of headache, visual disturbances and new-onset seizures. Brain imaging identified two enhancing central lesions and Balamuthia mandrillaris was later identified by brain biopsy. He received several months of various antimicrobials including miltefosine, a novel use of the drug in this disease at the time. Seven weeks into therapy, considerations were made to switch him to ‘comfort care’ because of worsening clinical status and seemingly lack of response to treatment. The patient finally demonstrated clinical and radiological improvement after eight weeks with modified therapy, despite experiencing some debilitating toxic effects likely to be related to antibiotics. Two years after his initial presentation he made a complete recovery. Conclusion: Balamuthia mandrillaris amoebic encephalitis is considered an almost universally fatal disease; this case demonstrates the possibility of recovery. This report outlines his treatment, drug toxicities and includes additional information regarding the therapeutic use of the drug miltefosine. Whether his survival is related to the specific antimicrobials used in this case is unknown and further investigation is warranted. PMID:28348755

    Adult male ruminants that were reared in contact with females display greater sexual behavior than those reared in single male groups. The aim of the experiment was to compare the reproductive development of prepubertal male kids reared with or without direct permanent contact with adult females until they were 10 months old. Seventeen Saanen male kids were maintained in two groups until 44 weeks of age: kids reared in permanent direct contact with four adult goats (group FEM, N = 8) and kids that remained isolated from females (group ISO, N = 9). All goats in the FEM group became pregnant approximately when bucks attained 28 weeks of age. Scrotal circumference and testosterone concentration were measured, and semen was obtained by electroejaculation to avoid female contact in the ISO group. Scrotal circumference was greater in FEM kids at 12 and 14 weeks of age (P < 0.0001) and testosterone when they were 20 and 22 weeks old (P < 0.0001). Testosterone concentration was greater in ISO kids from 28 to 44 weeks of age. All semen characteristics increased with age (P < 0.0001). Individual motility was greater in FEM kids than that in ISO kids at 15 and 17 weeks (P < 0.005); mass motility was greater in ISO than that in FEM kids at 32 weeks (P < 0.05); total number of spermatozoa/ejaculate was greater in ISO kids at 30, 32, and 40 weeks and in FEM kids at 43 weeks (P < 0.005); total number of motile spermatozoa was greater in ISO kids at 32 and 40 weeks, whereas at 43 weeks, it was greater in FEM kids (P < 0.005). It was concluded that permanent contact with adult goats had transient and short-time positive effects in male kids' reproductive traits during prepubertal development. However, positive effects stopped after goats used as stimulus became pregnant.

    Among computational models, voxel phantoms based on computer tomographic (CT), nuclear magnetic resonance (NMR) or colour photographic images of patients, volunteers or cadavers have become popular in recent years. Although being true to nature representations of scanned individuals, voxel phantoms have limitations, especially when walled organs have to be segmented or when volumes of organs or body tissues, like adipose, have to be changed. Additionally, the scanning of patients or volunteers is usually made in supine position, which causes a shift of internal organs towards the ribcage, a compression of the lungs and a reduction of the sagittal diameter especially in the abdominal region compared to the regular anatomy of a person in the upright position, which in turn can influence organ and tissue absorbed or equivalent dose estimates. This study applies tools developed recently in the areas of computer graphics and animated films to the creation and modelling of 3D human organs, tissues, skeletons and bodies based on polygon mesh surfaces. Female and male adult human phantoms, called FASH (Female Adult meSH) and MASH (Male Adult meSH), have been designed using software, such as MakeHuman, Blender, Binvox and ImageJ, based on anatomical atlases, observing at the same time organ masses recommended by the International Commission on Radiological Protection for the male and female reference adult in report no 89. 113 organs, bones and tissues have been modelled in the FASH and the MASH phantoms representing locations for adults in standing posture. Most organ and tissue masses of the voxelized versions agree with corresponding data from ICRP89 within a margin of 2.6%. Comparison with the mesh-based male RPI_AM and female RPI_AF phantoms shows differences with respect to the material used, to the software and concepts applied, and to the anatomies created.

    Traditional mosquito control strategies rely heavily on the use of chemical insecticides. However, concerns about the efficiency of traditional control methods, environmental impact and emerging pesticide resistance have highlighted the necessity for developing innovative tools for mosquito control. Some novel strategies, including release of insects carrying a dominant lethal gene (RIDL®), rely on the sustained release of modified male mosquitoes and therefore benefit from a thorough understanding of the biology of the male of the species. In this report we present the results of a mark-release-recapture study aimed at: (i) establishing the survival in the field of laboratory-reared, wild-type male Aedes aegypti and (b) estimating the size of the local adult Ae. aegypti population. The study took place in Panama, a country where recent increases in the incidence and severity of dengue cases have prompted health authorities to evaluate alternative strategies for vector control. Results suggest a life expectancy of 2.3 days for released male mosquitoes (confidence interval: 1.78-2.86). Overall, the male mosquito population was estimated at 58 males/ha (range 12-81 males/ha), which can be extrapolated to an average of 0.64 pupae/person for the study area. The practical implications of these results are discussed.

    The southern coastline of Australia forms part of the worlds' only northern boundary current system. The Bonney Upwelling occurs every austral summer along the south-eastern South Australian coastline, a region that hosts over 80% of the worlds population of an endangered endemic otariid, the Australian sea lion. We present the first data on the movement characteristics and foraging behaviour of adult male Australian sea lions across their South Australian range. Synthesizing telemetric, oceanographic and isotopic datasets collected from seven individuals enabled us to characterise individual foraging behaviour over an approximate two year time period. Data suggested seasonal variability in stable carbon and nitrogen isotopes that could not be otherwise explained by changes in animal movement patterns. Similarly, animals did not change their foraging patterns despite fine-scale spatial and temporal variability of the upwelling event. Individual males tended to return to the same colony at which they were tagged and utilized the same at-sea regions for foraging irrespective of oceanographic conditions or time of year. Our study contrasts current general assumptions that male otariid life history strategies should result in greater dispersal, with adult male Australian sea lions displaying central place foraging behaviour similar to males of other otariid species in the region.

    The effects of an extremely low frequency (ELF) magnetic field on the sex hormones and other fertility parameters of adult male Sprague-Dawley rats were investigated. Adult male rats were exposed to a 50 Hz sinusoidal magnetic field at approximately 25 microT (rms) for 18 consecutive weeks. There were no significant effects on the absolute body weight and the weight of the testes of the exposed rats. However, the weights of seminal vesicles and preputial glands were significantly reduced in the exposed male rats. Similarly, a significant reduction in sperm count was observed in the exposed group. Furthermore, there were no significant effects on the serum levels of male follicle stimulating hormone (FSH) during the 18 weeks of exposure period. On the other hand, there was a significant increase in the serum levels of male luteinizing hormone (LH) after 18 weeks of exposure (P < .005), while testosterone levels were significantly decreased only after 6 and 12 weeks of the exposure period. These results suggest that long term exposure to ELF could have adverse effects on mammalian fertility and reproduction.

    Objective With the growing number of childhood cancer survivors in the United States, it is important to assess the well-being of these individuals, particularly during the transitional phase of adolescence. Data about adolescent survivors’ overall health and quality of life will help identify survivor subgroups most in need of targeted attention to successfully transition to adulthood. Participants and Methods This ancillary study to the Childhood Cancer Survivor Study (CCSS) focused on children 15–19 years of age who had been diagnosed with cancer before the age of 4 years. A cohort of siblings of pediatric cancer survivors of the same ages served as a comparison sample. Adolescent health was assessed using the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) survey. Results The teen survey was sent to 444 survivor teens and 189 siblings. Of these 307(69%) survivors and 97 (51%) siblings completed and returned the survey. Overall health profiles of siblings and survivors were similar. Among survivors, females scored significantly below males on Satisfaction, Discomfort, and Disorders domains. Survivors diagnosed with CNS tumors scored less favorably than leukemia survivors in the global domains of Satisfaction and Disorders. Conclusion In general, adolescent survivors fare favorably compared to healthy siblings. However, identification of the subset of pediatric cancer survivors who are more vulnerable to medical and psychosocial disorders in adolescence provides the opportunity for design and implementation of intervention strategies that may improve quality of life.

    The synthetic estrogen 17α-ethinyl estradiol (EE2) disturbs reproduction and causes gonadal malformation in fish. Effects on the transcription of genes involved in gonad development and function that could serve as sensitive biomarkers of reproductive effects in the field is, however, not well known. We have studied mRNA expression in testes and liver of adult zebrafish (Danio rerio) males treated with 0, 5 or 25 ng/L EE2for 14 days. qPCR analysis showed that the mRNA expression of four genes linked to zebrafish male sex determination and differentiation, Anti-Mullerian Hormone, Double sex and mab-related protein, Sry-related HMG box-9a and Nuclear receptor subfamily 5 group number 1b were significantly decreased by 25 ng/L, but not 5 ng/L EE2 compared with the levels in untreated fish. The decreased transcription was correlated with a previously shown spawning failure in these males (Reyhanian et al., 2011. Aquat Toxicol 105, 41-48), suggesting that decreased mRNA expression of genes regulating male sexual function could be involved in the functional sterility. The mRNA level of Cytochrome P-45019a, involved in female reproductive development, was unaffected by hormone treatment. The transcription of the female-specific Vitellogenin was significantly induced in testes. While testicular Androgen Receptor and the Estrogen Receptor-alpha mRNA levels were unchanged, Estrogen receptor-beta was significantly decreased by 25 ng/L EE2. Hepatic Estrogen Receptor-alpha mRNA was significantly increased by both exposure concentrations, while Estrogen Receptor-beta transcription was unaltered. The decreased transcription of male-predominant genes supports a demasculinization of testes by EE2 and might reflect reproductive disturbances in the environment.

    Maternal environmental exposures during pregnancy are known to affect disease onset in adult offspring. For example, maternal asthma exacerbations during pregnancy can worsen adult asthma in the offspring. Cigarette smoking during pregnancy is associated with future onset of cardiovascular disease, obesity and diabetes. However, little is known about the effect of maternal environmental exposures on offspring susceptibility to liver disease. This pilot study examined the long-term effect of maternal allergen challenge and/or cigarette smoking during pregnancy on hepatic inflammation and fibrosis in adult mouse offspring. Ovalbumin (OVA) or phosphate-buffered saline (PBS)-sensitized/challenged CD-1 dams were exposed to mainstream cigarette smoke (MCS) or filtered air from gestational day 4 until parturition. Eight weeks postnatally, offspring were sacrificed for comparison of hepatic histology and mRNA expression. Adult male offspring of OVA-sensitized/challenged dams exposed to MCS (OSM) displayed significantly increased liver fibrosis (9.2% collagen content vs. <4% for all other treatment groups). These mice also had 1.8-fold greater collagen 1A1 mRNA levels. From the results here, we concluded that maternal allergen challenge in combination with cigarette smoke exposure during pregnancy may be an important risk factor for liver disease in adult male offspring.

    The Ginkgo biloba extract (GbE) is a commercial product used as a nutraceutic herbal remedy in Europe and US. It contains 27% of the polyphenols isorhamnetin, kaempferol, and quercetin, as antioxidants. We used male adult Wistar rats (200–300 g), divided into four groups: control group (treated with 5.0 mg/kg of sodium chloride, intravenous), titanium dioxide nanoparticles (TiO2-NPs) group (5.0 mg/kg, intravenous), GbE group (10 mg/kg, intraperitoneal), and GbE + TiO2-NPs group (treated 24 h before with 10 mg/kg of GbE, intraperitoneal), followed, 24 h later, by 5.0 mg/kg of TiO2-NPs intravenously. The statistical analysis was performed using Student's t-test for grouped data with ANOVA posttest. The GbE protected renal cells against the effects of TiO2-NPs because it reversed the increased activity of γ-glutamyltranspeptidase and the enzymatic activity of dipeptidylaminopeptidase IV at all times tested (0–5, 5–24, 24–48, and 48–72 h). Also it reversed the glucosuria, hypernatriuria, and urine osmolarity at three times tested (5–24, 24–48, and 48–72). Thus, we conclude that GbE has a beneficial activity in the cytoplasmic membranes of brush border cells on the renal tubules, against the adverse effects that can be produced by some xenobiotics in this case the TiO2-NPs, in experimental rats.

    Regular moderate-intensity exercise provides health benefits. The aim of this study was to examine whether the selected exercise intensity and physiological responses during exergaming in a single and multiplayer mode in the same physical space were game-dependent. Ten males (mean ±SD, age: 23 ±5 years, body mass: 84.2 ±15.6 kg, body height: 180 ±7 cm, body mass index: 26.0 ±4.0 kg·m−2) played the games Kinect football, boxing and track & field (3 × ∼10 min, ∼ 2 min rest periods) in similar time sequence in two sessions. Physiological responses were measured with the portable Cosmed K4b2 pulmonary gas exchange system. Single play demands were used to match with a competitive opponent in a multiplay mode. A within-subjects crossover design was used with one-way ANOVA and a post-hoc t-test for analysis (p<0.05). Minute ventilation, oxygen uptake and the heart rate were at least 18% higher during a multiplayer mode for Kinect football and boxing but not for track & field. Energy expenditure was 21% higher during multiplay football. Single play track & field had higher metabolic equivalent than single play football (5.7 ±1.6, range: 3.2–8.6 vs 4.1 ±1.0, range: 3.0–6.1, p<0.05). Exergaming in a multiplayer mode can provide higher physiological demands but the effects are game-dependent. It seems that exergaming with low intensity in a multiplayer mode may provide a greater physical challenge for participants than in a single play mode but may not consistently provide sufficient intensity to acquire health benefits when played regularly as part of a programme to promote and maintain health in young adults.

    The present study was devised to assess the effects of cadmium chloride (CdCl(2)) administration on certain andrological, endocrinological and biochemical alterations in adult male rabbits (n=24). The animals were assigned to control (n=8) and experimental (n=16) group. Experimental group was orally administered with 1.5 mg/kg body weight of CdCl(2). The trials were carried out for a total of 5 weeks and blood sampling was carried out on weekly basis. A gradual decrease was noticed for body weight in the experimental group from week 1 to 5, being significantly lower in week 4 and 5 (P<0.05). A similar decremented trend was noticed for serum testosterone level being significantly lower in experimental group in week 4 and 5 (P<0.001). Significantly lower values were noticed for prolactin in experimental group in week 4 and 5 (P<0.05), than in the control. On the contrary, serum cortisol level showed a gradual increase in experimental group, from week 1 to 5, being significantly higher in week 4 and 5 (P<0.05). Regarding the biochemical attributes, all the parameters under study revealed a gradually ascending trend. Statistical significance was, however, achieved in varying weeks and at varying levels. The total protein and albumin were significantly higher in week 4 and 5 (P<0.01); alanine aminotransferase in week 2 (P<0.01), 3 (P<0.001), 4 (P<0.01) and 5 (P<0.001); aspartate aminotransferase in week 1, 2, 3, 4 and 5 (P<0.01); and alkaline phosphatase in week 1, 2 (P<0.01), 3, 4 and 5 (P<0.0001), respectively. Overall mortality rate in experimental group was 68.75 (11/16). In a nutshell, Cd exposure results in adverse effects on all physiological parameters of body and may lead to lethal consequences.

    Background: Formaldehyde is used in medicine and industry, and it is known to have detrimental effects on various systems including the nervous system, by increasing oxidative stress. However, data are scarce related to substances that can protect against the neurotoxicity induced by formaldehyde. Therefore, this study was designed to assess the protective effects of selenium against the toxic effect of this compound. Methods: A total of 48 adult male mice were divided randomly into six groups, i.e., (1) control, (2) treated with formaldehyde, (3) treated with formaldehyde plus 0.1 mg/kg selenium, (4) treated with formaldehyde plus 0.2 mg/kg selenium, (5) treated with formaldehyde plus 0.4 mg/kg selenium, and (6) treated with formaldehyde plus 0.8 mg/kg selenium. At the end of 14 days, the cerebellums were removed for histological evaluation. Morphological changes were examined using Image J software. The data were analyzed using SPSS software version 20.0 and analysis of variance (ANOVA). Results: Formaldehyde caused a reduction in the numbers and sizes of Purkinje cells and granular cells; in addition, the thickness of the granular layer was thinner than that in the control mice (P < 0.05). Treatment with 0.1 mg/kg selenium resulted in an increase in the number of Purkinje cells as well as the area of the gray matter compared to those of the control mice. Conclusion: Formaldehyde-induced neuronal damage was prevented by the administration of 0.1 mg/kg selenium, hence this treatment shows therapeutic potential for the treatment of neurotoxicity PMID:25763172

    Objective To assess the safety, effectiveness and acceptability of the PrePex device for adult medical male circumcision (MMC) in routine service delivery in Kenya. Methods We enrolled 427 men ages 18–49 at one fixed and two outreach clinics. Procedures were performed by trained clinical officers and nurses. The first 50 enrollees were scheduled for six follow-up visits, and remaining men were followed at Days 7 and 42. We recorded adverse events (AEs) and time to complete healing, and interviewed men about acceptability and pain. Results Placement and removal procedures each averaged between 3 and 4 minutes. Self-reported pain was minimal during placement but was fleetingly intense during removal. The rate of moderate/severe AEs was 5.9% overall (95% confidence interval [CI] 3.8%–8.5%), all of which resolved without sequelae. AEs included 5 device displacements, 2 spontaneous foreskin detachments, and 9 cases of insufficient foreskin removal. Surgical completion of MMC was required for 9 men (2.1%). Among the closely monitored first 50 participants, the probability of complete healing by Day 42 was 0.44 (95% CI 0.30–0.58), and 0.90 by Day 56. A large majority of men was favorable about their MMC procedure and would recommend PrePex to friends and family. Conclusions The PrePex device was effective for MMC in Kenya, and well-accepted. The AE rate was higher than reported for surgical procedures there, or in previous PrePex studies. Healing time is longer than following surgical circumcision. Provider experience and clearer counseling on post-placement and post-removal care should lead to lower AE rates. Trial Registration ClinicalTrials.gov NCT01711411 PMID:24788898

    2010-01-01

    Abstract Most experimental models of spinal cord injury (SCI) in rodents induce damage in the thoracic cord and subsequently examine hindlimb function as an indicator of recovery. In these models, functional recovery is most attributable to white-matter preservation and is less influenced by grey-matter sparing. In contrast, most clinical cases of SCI occur at the lower cervical levels, a region in which both grey-matter and white-matter sparing contribute to functional motor recovery. Thus experimental cervical SCI models are beginning to be developed and used to assess protective and pharmacological interventions following SCI. The objective of this study was to characterize a model of graded cervical hemicontusion SCI with regard to several histological and behavioral outcome measures, including novel forelimb behavioral tasks. Using a commercially available rodent spinal cord impactor, adult male rats received hemicontusion SCI at vertebral level C5 at 100, 200, or 300 kdyn force, to produce mild, moderate, or severe injury severities. Tests of skilled and unskilled forelimb and locomotor function were employed to assess functional recovery, and spinal cord tissue was collected to assess lesion severity. Deficits in skilled and unskilled forelimb function and locomotion relating to injury severity were observed, as well as decreases in neuronal numbers, white-matter area, and white-matter gliosis. Significant correlations were observed between behavioral and histological data. Taken together, these data suggest that the forelimb functional and locomotor assessments employed here are sensitive enough to measure functional changes, and that this hemicontusion model can be used to evaluate potential protective and regenerative therapeutic strategies.

    Autism Spectrum Disorder (ASD) is diagnosed on the basis of behavioral symptoms, but cognitive abilities may also be useful in characterizing individuals with ASD. One hundred seventy-eight high-functioning male adults, half with ASD and half without, completed tasks assessing IQ, a broad range of cognitive skills, and autistic and comorbid symptomatology. The aims of the study were, first, to determine whether significant differences existed between cases and controls on cognitive tasks, and whether cognitive profiles, derived using a multivariate classification method with data from multiple cognitive tasks, could distinguish between the two groups. Second, to establish whether cognitive skill level was correlated with degree of autistic symptom severity, and third, whether cognitive skill level was correlated with degree of comorbid psychopathology. Fourth, cognitive characteristics of individuals with Asperger Syndrome (AS) and high-functioning autism (HFA) were compared. After controlling for IQ, ASD and control groups scored significantly differently on tasks of social cognition, motor performance, and executive function (P's < 0.05). To investigate cognitive profiles, 12 variables were entered into a support vector machine (SVM), which achieved good classification accuracy (81%) at a level significantly better than chance (P < 0.0001). After correcting for multiple correlations, there were no significant associations between cognitive performance and severity of either autistic or comorbid symptomatology. There were no significant differences between AS and HFA groups on the cognitive tasks. Cognitive classification models could be a useful aid to the diagnostic process when used in conjunction with other data sources—including clinical history.

    Schistosoma mansoni and its vertebrate host have a complex and intimate connection in which several molecular stimuli are exchanged and affect both organisms. Human tumor necrosis factor alpha (hTNF-α), a pro-inflammatory cytokine, is known to induce large-scale gene expression changes in the parasite and to affect several parasite biological processes such as metabolism, egg laying, and worm development. Until now, the molecular mechanisms for TNF-α activity in worms are not completely understood. Here, we aimed at exploring the effect of hTNF-α on S. mansoni protein phosphorylation by 2D gel electrophoresis followed by a quantitative analysis of phosphoprotein staining and protein identification by mass spectrometry. We analyzed three biological replicates of adult male worms exposed to hTNF-α and successfully identified 32 protein spots with a statistically significant increase in phosphorylation upon in vitro exposure to hTNF-α. Among the differentially phosphorylated proteins, we found proteins involved in metabolism, such as glycolysis, galactose metabolism, urea cycle, and aldehyde metabolism, as well as proteins related to muscle contraction and to cytoskeleton remodeling. The most differentially phosphorylated protein (30-fold increase in phosphorylation) was 14-3-3, whose function is known to be modulated by phosphorylation, belonging to a signal transduction protein family that regulates a variety of processes in all eukaryotic cells. Further, 75% of the identified proteins are known in mammals to be related to TNF-α signaling, thus suggesting that TNF-α response may be conserved in the parasite. We propose that this work opens new perspectives to be explored in the study of the molecular crosstalk between host and pathogen.

    Human scalp hair as a biopsy material may well serve the purpose of estimating the degree of human exposure to environmental contaminants, especially trace metals. To this effect, the levels of trace metals in hair of various groups of population living in areas with varying extent of environmental exposure are generally compared together. Such comparative evaluations are important since they are unique for each group of population and probably reflect not only a number of factors of genetical, nutritional and environmental origin, but also indicate relationship with factors such as food, ambient air, drinking water, occupational exposure, age, race, sex and metabolic condition etc. Also there are some elements which are selectively deposited in hair and may thus provide clinical information on the level of exposure and toxication. The aim of the present study was two-fold: to collect base-line trace metal data on hair and to evaluate the metal levels as measure of the nutritional status of the relevant groups of urban and rural population in terms of industrial, agricultural and occupation exposure. For this purpose, scalp hair samples were obtained from donors belonging to urban adult male population from the city of Peshawer and a rural town, Jamrood and were investigated for three essential metals (Na, K and Zn) and four non-essential metals (Co, Hg, As and Ag) by AAS technique. The impact of urban and rural environments, including the food habits of individuals, on trace metal distribution in scalp hair of the two classes of population is then reviewed with reference to the literature data available from other parts of the world. 16 refs., 5 tabs.

    The aim of the present study was to compare effect of three low doses of morphine (MOR) and delta9-tetrahydrocannabinol (THC) on social behavior tested in Social interaction test (SIT). 45 min prior to testing adult male rats received one of the drugs or solvents: MOR (1; 2.5; 5 mg/kg); saline as a solvent for MOR; THC (0.5; 1; 2 mg/kg); ethanol as a solvent for THC. Occurrence and time spent in specific patterns of social interactions (SI) and non-social activities (locomotion and rearing) was video-recorded for 5 min and then analyzed. MOR in doses of 1 and 2.5 mg/kg displayed decreased SI in total. Detailed analysis of specific patterns of SI revealed decrease in mutual sniffing and allo-grooming after all doses of MOR. The highest dose (5 mg/kg) of MOR decreased following and increased genital investigation. Rearing activity was increased by lower doses of MOR (1 and 2.5 mg/kg). THC, in each of the tested doses, did not induce any specific changes when compared to matching control group (ethanol). However, an additional statistical analysis showed differences between all THC groups and their ethanol control group when compared to saline controls. There was lower SI in total, lower mutual sniffing and allo-grooming, but higher rearing in THC and ethanol groups than in saline control group. Thus, changes seen in THC and ethanol groups are seemed to be attributed mainly to the effect of the ethanol. Based on the present results we can assume that opioids affect SI more than cannabinoid.

    Previous studies have recently shown that maternal hypothyroidism leads to impaired glucose metabolism and reduced insulin secretion in adult offspring in rats. The aim of this study was to locate the defect in the insulin secretion pathway induced by maternal hypothyroidism. Pregnant Wistar rats were divided into two groups; the control group consumed water, while the hypothyroid (FH) group received water containing 0.025% 6-propyl-2-thiouracil during gestation. An intravenous glucose tolerance test was carried out on 5-month-old male offspring. In in vitro studies, the effects of various secretagogues and inhibitors acting at different levels of the insulin secretion cascade were investigated, and insulin content, insulin secretion and glucokinase activity of the islets were compared. Although insulin content of the FH islets did not differ from that of control islets, insulin secretion from FH islets was reduced when it was challenged by glucose or arginine. Compared with control islets, activities of both hexokinase and glucokinase were also significantly decreased in the FH islets. Although, in both groups, increasing glibenclamide and nifedipine concentrations in the presence of 16.7 mmol l(-1) glucose increased and decreased insulin secretion, respectively, the percentage of changes in secretion of FH islets was significantly lower compared with control islets. The response of FH islets to high extracellular potassium concentration and diazoxide was also significantly lower than that of the control islets. These findings demonstrate that impaired insulin secretion in the FH group is probably related to alterations in different steps of the insulin secretion pathway and not in the insulin pool of β-cells.

    The International Space Station will allow extended habitation in space and long-term exposure to microgravity (microG). A concern is the impact of long-term microG exposure on the ability of species to reproduce. The model often used to simulate microG is rat hindlimb suspension (HLS), where the hindlimbs are elevated above the cage floor with a tail harness. Experiments described here are the first to examine the effect of long-term HLS on testicular function in adult male rats. Free-roaming (controls), animals with only the tail harnessed but hindlimbs in contact with the cage floor (TO), and HLS animals were tested for 6 wk. Cryptorchidism was prevented in TO and HLS animals by partial constriction of the inguinal canal with sutures. All parameters were compared at the end of the 6-wk experiment. Testicular weights and spermatogenesis were significantly reduced by HLS, such that no spermatogenic cells beyond round spermatids were present and epididymides were devoid of mature sperm. In many tubules, loss of all germ cells, except a few spermatogonia, resulting in histopathology similar to the Sertoli cell, was observed. Spermatogenesis appeared unaffected in control and TO animals. Sertoli and Leydig cell appearance, testosterone, luteinizing hormone, and follicle-stimulating hormone levels, and epididymal and seminal vesicle weight were unchanged by HLS. Cortisone was not elevated by HLS; thus stress may not be a factor. These results demonstrate that spermatogenesis is severely inhibited by long-term HLS, whereas testicular androgen production is not. These results have significant implications regarding serious effects of long-term exposure to microG on the reproductive capability of scrotal mammals, including humans.

The aim of this study was to examine whether the selected exercise intensity and physiological responses during exergaming in a single and multiplayer mode in the same physical space were game-dependent. Ten males (mean ±SD, age: 23 ±5 years, body mass: 84.2 ±15.6 kg, body height: 180 ±7 cm, body mass index: 26.0 ±4.0 kg·m(-2)) played the games Kinect football, boxing and track & field (3 × ∼10 min, ∼ 2 min rest periods) in similar time sequence in two sessions.

A within-subjects crossover design was used with one-way ANOVA and a post-hoc t-test for analysis (p<0.05). Minute ventilation, oxygen uptake and the heart rate were at least 18% higher during a multiplayer mode for Kinect football and boxing but not for track & field.

Single play track & field had higher metabolic equivalent than single play football (5.7 ±1.6, range: 3.2-8.6 vs 4.1 ±1.0, range: 3.0-6.1, p<0.05). Exergaming in a multiplayer mode can provide higher physiological demands but the effects are game-dependent. It seems that exergaming with low intensity in a multiplayer mode may provide a greater physical challenge for participants than in a single play mode but may not consistently provide sufficient intensity to acquire health benefits when played regularly as part of a programme to promote and maintain health in young adults.

    The calculation of radiation dose from internally incorporated radionuclides is based on so-called absorbed fractions (AFs) and specific absorbed fractions (SAFs). SAFs for monoenergetic electrons were calculated for 63 source regions and 67 target regions using the new male and female adult reference computational phantoms adopted by the ICRP and ICRU and the Monte Carlo radiation transport programme package EGSnrc. The SAF values for electrons are opposed to the simplifying assumptions of ICRP Publication 30. The previously applied assumption of electrons being fully absorbed in the source organ itself is not always true at electron energies above approximately 300-500 keV. High-energy electrons have the ability to leave the source organ and, consequently, the electron SAFs for neighbouring organs can reach the same magnitude as those for photons for electron energies above 1 MeV. The reciprocity principle known for photons can be extended to electron SAFs as well, thus making cross-fire electron SAFs mass-independent. To quantify the impact of the improved electron dosimetry in comparison to the dosimetry using the simple assumptions of ICRP Publication 30, absorbed doses per administered activity of three radiopharmaceuticals were evaluated with and without explicit electron transport. The organ absorbed doses per administered activity for the two evaluation methods agree within 2%-3% for most organs for radionuclides with decay spectra having electron energies below a few hundred keV and within approximately 20% if higher electron energies are involved. An important exception is the urinary bladder wall, where the dose is overestimated by 60-150% using the simplified ICRP 30 approach for the radiopharmaceuticals of this study.

    Adult zebra finches (T. guttata) form socially monogamous pair bonds characterized by proximity, vocal communication, and contact behaviors. In this experiment, we tested whether manipulations of the nonapeptide hormone arginine vasotocin (AVT, avian homolog of vasopressin) and the V1a receptor (V1aR) early in life altered species-typical pairing behavior in adult zebra finches of both sexes. Although there was no effect of treatment on the tendency to pair in either sex, males in different treatments exhibited profoundly different profiles of pair maintenance behavior. Following a brief separation, AVT-treated males were highly affiliative with their female partner but sang very little compared to Controls. In contrast, males treated with a V1aR antagonist sang significantly less than Controls, but did not differ in affiliation. These effects on behavior in males were also reflected in changes in the expression of V1aR and immediate early gene activity in three brain regions known to be involved in pairing behavior in birds: the medial amygdala, medial bed nucleus of the stria terminalis, and the lateral septum. AVT males had higher V1aR expression in the medial amygdala than both Control and antagonist-treated males and immediate early gene activity of V1aR neurons in the medial amygdala was positively correlated with affiliation. Antagonist treated males showed decreased activity in the medial amygdala. In addition, there was a negative correlation between the activity of V1aR cells in the medial bed nucleus of the stria terminalis and singing. Treatment also affected the expression of V1aR and activity in the lateral septum, but this was not correlated with any behaviors measured. These results provide evidence that AVT and V1aR play developmental roles in specific pair maintenance behaviors and the neural substrate underlying these behaviors in a bird. PMID:27065824

    Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed. PMID:24799477

    Female-to-male trans masculine adults who have sex with cisgender (non-transgender) males (TMSM) represent an understudied population in relation to HIV/sexually transmitted infection (STI) risk. This study examined the role of syndemic conditions and social gender affirmation processes (living full-time in one's identified gender) in potentiating sexual risk among TMSM adults in Massachusetts, US. Cross-sectional data were restricted to TMSM who reported lifetime sexual behaviour with a cisgender male (n = 173; mean age = 29.4, SD = 9.6; 18.5% people of colour; 93.1% non-heterosexual identity; 56.1% hormones/surgery). Sexual risk outcomes were: lifetime STI diagnoses, three or more sexual partners in the previous six months, and condomless anal/vaginal sex at last encounter with a cisgender male. Age- and survey mode-adjusted logistic regression models regressed sexual risk outcomes on the main effect of syndemics (six indicators summed: binge drinking, substance use, depression, anxiety, childhood abuse, intimate partner violence), followed by the interaction of syndemics and social gender affirmation. Syndemics were associated with increased odds of all sexual risk indicators (adjusted odds ratios [aORs] = 1.32-1.55; p < 0.0001). Social gender affirmation moderated the association between syndemics and condomless anal/vaginal sex at last encounter with a cisgender male (p < 0.0001). Syndemics were associated with sexual risk in TMSM who had socially affirmed their gender (aOR = 1.79; 95% CI = 1.42-2.25; p < 0.001), but not among those TMSM who had not (aOR = 0.86; 95% CI = 0.63-1.19; p = 0.37). Findings suggest that syndemic pathways to sexual risk are similar for TMSM who have socially gender affirmed as for cisgender MSM. Integration of syndemics and gender affirmation frameworks is recommended in interventions to address TMSM sexual risk.

    2016-01-01

    Drawing from trauma theory, psychodynamic conceptualization, developmental psychology, clinical data, and personal experience, this article portrays a life haunted by tragedy predating its victims. Healthy child development is outlined, with particular attention to socialization and theological perspectives. Key characteristics of trauma are delineated, highlighting the nuances of trauma that are most harmful. As is the case with general trauma, Holocaust survivors are described as evincing survivor's guilt and paranoia in response to their experiences. Divergent disorders resulting from the Holocaust are described for 1st-generation and 2nd-generation survivors, respectively. Primary trauma responses and pervasive attitudes of survivors are shown to have harmful ramifications on their children's personality and worldview as well as on their interpersonal and theistic object relations. These limitations translate into problems in the adult lives of second generation survivors.

    Drug abuse of pregnant women is a growing problem. The effect of prenatal drug exposure may have devastating effect on development of the offsprings that may be long-term or even permanent. One of the most common drug abused by pregnant women is methamphetamine (MA), which is also the most frequently abused illicit drug in the Czech Republic. Our previous studies demonstrated that prenatal MA exposure alters behavior, cognition, pain and seizures in adult rats in sex-specific manner. Our most recent studies demonstrate that prenatal MA exposure makes adult rats more sensitive to acute injection of the same or related drugs than their controls. The aim of the present study was to examine the effect of prenatal MA exposure on drug-seeking behavior of adult male rats tested in the Conditioned place preference (CPP). Adult male rats were divided to: prenatally MA-exposed (5 mg/kg daily for the entire prenatal period), prenatally saline-exposed (1 ml/kg of physiological saline) and controls (without maternal injections). The following drugs were used in the CPP test in adulthood: MA (5 mg/kg), amphetamine (5 mg/kg), cocaine (5 and 10 mg/kg), morphine (5 mg/kg), MDMA (5 mg/kg) and THC (2 mg/kg). Our data demonstrated that prenatally MA-exposed rats displayed higher amphetamine-seeking behavior than both controls. MA as well as morphine induced drug-seeking behavior of adult male rats, however this effect did not differ based on the prenatal MA exposure. In contrast, prenatal MA exposure induced rather tolerance to cocaine than sensitization after the conditioning in the CPP. MDMA and THC did not induce significant effects. Even though the present data did not fully confirmed our hypotheses, future studies are planned to test the drug-seeking behavior also in self-administration test.

    In this study, we developed a structured risk checklist, the Child Pornography Offender Risk Tool (CPORT), to predict any sexual recidivism among adult male offenders with a conviction for child pornography offenses. We identified predictors of sexual recidivism using a 5-year fixed follow-up analysis from a police case file sample of 266 adult male child pornography offenders in the community after their index offense. In our 5-year follow-up, 29% committed a new offense, and 11% committed a new sexual offense, with 3% committing a new contact sexual offense against a child and 9% committing a new child pornography offense. The CPORT items comprised younger offender age, any prior criminal history, any contact sexual offending, any failure on conditional release, indication of sexual interest in child pornography material or prepubescent or pubescent children, more boy than girl content in child pornography, and more boy than girl content in other child depictions. The CPORT was significantly associated with any sexual recidivism, with moderate predictive accuracy, and thus has promise in the risk assessment of adult male child pornography offenders with further cross-validation.

    Writing in plain language makes it easier for patients to read, understand, and make informed decisions about sperm banking. Greater attention to the issue and properly designed educational brochures for use by nurses in oncology and reproductive health is of evident importance but of unknown impact. A multidisciplinary clinical team followed an evidence-based, patient-centered approach to develop "plain language" patient education materials about sperm banking for adolescent and young adult (AYA) males with cancer. A patient education booklet was produced and implemented as part of the planned patient education for AYA male oncology patients at McMaster Children's Hospital, Hamilton Health Sciences, in Hamilton, Ontario, Canada. The patient education booklet for use by health professionals as a teaching tool to facilitate discussion with AYA males has been produced with the hope that it will contribute to better informed decision making regarding sperm banking and increased use of this technology for fertility preservation.

    The new concept of mammalian sex maintenance establishes that particular key genes must remain active in the differentiated gonads to avoid genetic sex reprogramming, as described in adult ovaries after Foxl2 ablation. Dmrt1 plays a similar role in postnatal testes, but the mechanism of adult testis maintenance remains mostly unknown. Sox9 and Sox8 are required for postnatal male fertility, but their role in the adult testis has not been investigated. Here we show that after ablation of Sox9 in Sertoli cells of adult, fertile Sox8-/- mice, testis-to-ovary genetic reprogramming occurs and Sertoli cells transdifferentiate into granulosa-like cells. The process of testis regression culminates in complete degeneration of the seminiferous tubules, which become acellular, empty spaces among the extant Leydig cells. DMRT1 protein only remains in non-mutant cells, showing that SOX9/8 maintain Dmrt1 expression in the adult testis. Also, Sox9/8 warrant testis integrity by controlling the expression of structural proteins and protecting Sertoli cells from early apoptosis. Concluding, this study shows that, in addition to its crucial role in testis development, Sox9, together with Sox8 and coordinately with Dmrt1, also controls adult testis maintenance.

    This work discusses the dose computations of 80 kV diagnostic x-rays made on a mathematical phantom representing an average Indian adult, since it is felt that results based on MIRD adult phantom calculations are not strictly appropriate for the population in India. Normalized organ equivalent doses and effective doses for an Indian adult male have been estimated. Normalization is done with respect to the entrance skin dose of the patient. Twenty common diagnostic x-ray examinations have been considered in this study and the doses are presented. This study would enable estimation of radiation induced detriment to the patient subpopulation in India. Since the external dimensions of the phantom are nearly the same as that of 15-y-old NRPB pediatric phantom, our results are also compared with those of latter and the agreement was found to be satisfactory.

    Methoprene is a juvenile hormone analog commonly used for the control of mosquito larvae. It acts through interference with normal metamorphosis, resulting in mortality prior to and during adult emergence. Methoprene is not commonly used for the control of adult mosquitoes, due to an absence of acute effects. Here, we have evaluated for chronic effects caused by the exposure of adult Aedes aegypti mosquitoes to methoprene. We applied methoprene to adults, both through 1) topical application to the abdomen and 2) as an aerosol, examining for treatment effects on ovary development, adult longevity, and fecundity. The results demonstrate that relatively high doses are required to affect adult survivorship. In contrast, significant impacts on both fecundity and egg hatch were observed in females treated at the lower dosages. We discuss the results in relation to autocidal strategies for mosquito control in which the release of fecund females is to be avoided.

    Purpose: To evaluate the effect of antiepileptic drugs (AEDs) on cognition and behavior in adult epileptic males controlled on treatment with conventional antiepileptic medications. Methods: Cognitive, mood, behavior and personality traits were assessed in 45 epileptic patients treated with carbamazepine and/or valproate and free of seizures for ≥1 year. Thirty-four newly diagnosed or untreated patients with epilepsy and 58 matched healthy subjects were also included for comparison. A battery of psychometric tests was utilized including Stanford-Binet (4th edition), Beck Inventory for Depression, Aggressive Scale and Eysenck Personality Questionnaire. Results: Compared to matched control subjects, treated and untreated epileptic patients had poor performance in different cognitive and behavioral functions testing. Treated patients had worse scores in memory for digits forward and backward, total short-term memory, extroversion and psychosis. The duration of AEDs intake was correlated with memory of objects (r = −0.323; P = 0.030), bead memory (r = −0.314; P = 0.036) and total nonverbal short-term memory (r = −0.346; P = 0.020). Treated and untreated epileptic patients had poor performance of similar extent in behavioral functions testing (depression, aggression and neurosis). The dose of AEDs was correlated with testing scores for neurosis (r = 0.307; P = 0.040), verbal aggression (r = 0.483; P = 0.001) and nonverbal aggression (r = 0.526; P = 0.000), and duration of drug intake was correlated with scores for depression (r = 0.384; P = 0.009), psychosis (r = 0.586; P = 0.0001) and nonverbal aggression (r = 0.300; P = 0.045). Conclusions: This study provides support for the notion that AEDs can impair performance in cognition, mood and behavior. Duration of drug intake and the number of the utilized AEDs are the main confounding variables. This study did not provide clues on how to exclude the effect of epilepsy itself and psychosocial variables as

    Life stage is an important risk factor for toxicity. Children and aging adults, for example, are more susceptible to certain chemicals than are young adults. In comparison to children, relatively little is known about susceptibility in older adults. Additionally, few studies have compared toxicant susceptibility across a broad range of life stages. Results are presented for behavioral evaluations of male Brown Norway rats obtained as adolescents (1 month), or young (4 months), middle-age (12 months) and senescent (24 months) adults. Motor activity was evaluated in photocell devices during 30-min sessions. Age-related baseline characteristics and sensitivity to toluene (0, 300, 650, or 1000mg/kg, p.o.) were determined. In Experiment 1, young-adult, middle-age and senescent rats were treated with corn-oil vehicle before five weekly test sessions. Baselines of horizontal and vertical activity decreased with age, but each age-group's averages remained stable across weeks of testing. Baseline activity of older rats was more variable than that of the young adults; older rats were also more variable individually from week to week. Toluene (1000mg/kg) increased horizontal activity proportionately more in senescent rats (ca. 300% of control) than in middle-age or young-adult rats (ca.145-175% of control). Experiment 2 established toluene dose-effect functions in individual adolescent, young-adult, middle-age and senescent rats; each rat received all treatments, counterbalanced across four weekly sessions. Toluene produced dose-related increases in horizontal activity that increased proportionately with age. Experiment 3 replicated the effects of toluene (1000mg/kg) in Experiment 1, showing that toluene-induced increases in horizontal activity were greatest in the oldest rats. Collectively, the results show that aging increased susceptibility to toluene and also increased variability in toluene response. Given the rapid growth of the aged population, further research is

    Psychopathic traits are linked with impairments in emotional facial expression recognition. These impairments may, in part, reflect reduced attention to the eyes of emotional faces. Although reduced attention to the eyes has been noted among children with conduct problems and callous-unemotional traits, similar findings are yet to be found in relation to psychopathic traits among adult male participants. Here we investigated the relationship of primary (selfish, uncaring) and secondary (impulsive, antisocial) psychopathic traits with attention to the eyes among adult male non-offenders during an emotion recognition task. We measured the number of fixations, and overall dwell time, on the eyes, and the mouth of male and female faces showing the six basic emotions at varying levels of intensity. We found no relationship of primary or secondary psychopathic traits with recognition accuracy. However, primary psychopathic traits were associated with a reduced number of fixations, and lower overall dwell time, on the eyes relative to the mouth across expressions, intensity, and sex. Furthermore, the relationship of primary psychopathic traits with attention to the eyes of angry and fearful faces was influenced by the sex and intensity of the expression. We also showed that a greater number of fixations on the eyes, relative to the mouth, were associated with increased accuracy for angry and fearful expression recognition. These results are the first to show effects of psychopathic traits on attention to the eyes of emotional faces in an adult male sample, and may support amygdala based accounts of psychopathy. These findings may also have methodological implications for clinical studies of emotion recognition. PMID:26500524

    2012-01-01

    Background Adult patients with hypothalamic-pituitary disorders have compromised quality of life (QoL). Whether this is due to their endocrine consequences (hypopituitarism), their underlying hypothalamic-pituitary disorder or both is still under debate. The aim of this trial was to measure quality of life (QoL) in long-term cancer survivors who have received a radiation dose to the basal part of the brain and the pituitary. Methods Consecutive patients (n=101) treated for oropharyngeal or epipharyngeal cancer with radiotherapy followed free of cancer for a period of 4 to10 years were identified. Fifteen patients (median age 56 years) with no concomitant illness and no hypopituitarism after careful endocrine evaluation were included in a case-control study with matched healthy controls. Doses to the hypothalamic-pituitary region were calculated. QoL was assessed using the Symptom check list (SCL)-90, Nottingham Health Profile (NHP), and Psychological Well Being (PGWB) questionnaires. Level of physical activity was assessed using the Baecke questionnaire. Results The median accumulated dose was 1.9 Gy (1.5–2.2 Gy) to the hypothalamus and 2.4 Gy (1.8–3.3 Gy) to the pituitary gland in patients with oropharyngeal cancer and 6.0–9.3 Gy and 33.5–46.1 Gy, respectively in patients with epipharyngeal cancer (n=2). The patients showed significantly more anxiety and depressiveness, and lower vitality, than their matched controls. Conclusion In a group of long time survivors of head and neck cancer who hade received a low radiation dose to the hypothalamic-pituitary region and who had no endocrine consequences of disease or its treatment QoL was compromised as compared with well matched healthy controls.

    This study examined whether the death of family members intensifies the survivors' posttraumatic stress and behavioral changes. Data were collected by interviewing 416 adult survivors from nine habitations of the Nagapattinam district in the state of Tamil Nadu in India 14 months after the 2004 tsunami. Compared to those nonbereaved, bereaved survivors reported more posttraumatic stress disorder, depression, anxiety, negative affect, deteriorated mental health, adverse physical health symptoms, alcohol consumption, family conflicts, and fear. When a tsunami trauma includes death of a loved one, psychological, physical, and behavioral ramifications are especially severe.

    Patients with Congenital Adrenal Hyperplasia (CAH) owing to 21-hydroxylase deficiency and whose karyotype is 46, XX are usually assigned to the female gender. Reported herein are the long term outcomes in three patients with CAH whose karyotype is 46, XX and who were reared as males. A retrospective review of three CAH patients with a 46, XX karyotype who were reared as males was conducted. Gender assignment, clinical and biochemical data, pre and post-genitoplasty genital examinations were reviewed. Gender identity was tested by an extensive questionnaire. Gender role, sexual preference, marital status and sexual satisfaction were evaluated by interview. The three patients were genotyped for the CYP21A2 gene confirming the diagnosis of CAH. Owing to genital virilization, cultural preferences for male gender and the lack of newborn screening programs the three patients reported herein were assigned to the male gender at birth before the diagnosis of CAH was established. In adulthood the patients remained significantly virilized. Thorough psychosexual assessments in adulthood revealed well established male gender identities compatible with their male gender assignments at birth. In all three patients, gender role and behavior were consistent with male gender identity including sexual intercourse with female partners. The three patients reported herein revealed that male gender assignment to CAH patients with a 46, XX karyotype may have a successful outcome providing there is strong parental support and expert endocrine care. No standard guidelines have been published for the gender assignment of CAH patients with a 46, XX karyotype and genital ambiguity. More studies concerning gender assignment in CAH patients with a 46, XX karyotype reared as males are needed.

    2013-02-01

    Adolescent drug abuse is hypothesized to increase the risk of drug addiction. Yet male rats that self-administer heroin as adolescents show attenuated drug-seeking after abstinence, compared with adults. Here we explore a role for neural activity in the medial prefrontal cortex (mPFC) in age-dependent heroin-seeking. Adolescent (35-day-old at start; adolescent-onset) and adult (86-day-old at start) male rats acquired lever-pressing maintained by heroin using a fixed ratio one reinforcement schedule (0.05 and 0.025 mg/kg per infusion). Following 12 days of forced abstinence, rats were tested for heroin-seeking over 1 h by measuring the number of lever presses on the active lever. Unbiased stereology was then used to estimate the number of Fos-ir(+) and Fos-ir(-) neurons in prelimbic and infralimbic mPFC. As before, adolescents and adults self-administered similar amounts of heroin, but subsequent heroin-seeking was attenuated in the younger rats. Similarly, the adolescent-onset group failed to show significant neural activation in the prelimbic or infralimbic mPFC during the heroin-seeking test, whereas the adult-onset heroin self-administration group showed two to six times more Fos-ir(+) neurons than their saline counterparts in both mPFC subregions. Finally, the overall number of neurons in the infralimbic cortex was greater in rats from the adolescent-onset groups than adults. The mPFC may thus have a key role in some age-dependent effects of heroin self-administration.

    The developing immune system displays a relatively high sensitivity as compared to both general toxicity parameters and to the adult immune system. In this study we have performed such comparisons using di(2-ethylhexyl) phthalate (DEHP) as a model compound. DEHP is the most abundant phthalate in the environment and perinatal exposure to DEHP has been shown to disrupt male sexual differentiation. In addition, phthalate exposure has been associated with immune dysfunction as evidenced by effects on the expression of allergy. Male wistar rats were dosed with corn oil or DEHP by gavage from postnatal day (PND) 10–50 or PND 50–90 at doses between 1 and 1000 mg/kg/day. Androgen-dependent organ weights showed effects at lower dose levels in juvenile versus adult animals. Immune parameters affected included TDAR parameters in both age groups, NK activity in juvenile animals and TNF-α production by adherent splenocytes in adult animals. Immune parameters were affected at lower dose levels compared to developmental parameters. Overall, more immune parameters were affected in juvenile animals compared to adult animals and effects were observed at lower dose levels. The results of this study show a relatively higher sensitivity of juvenile versus adult rats. Furthermore, they illustrate the relative sensitivity of the developing immune system in juvenile animals as compared to general toxicity and developmental parameters. This study therefore provides further argumentation for performing dedicated developmental immune toxicity testing as a default in regulatory toxicology. -- Highlights: ► In this study we evaluate the relative sensitivities for DEHP induced effects. ► Results of this study demonstrate the age-dependency of DEHP toxicity. ► Functional immune parameters were more sensitive than structural immune parameters. ► Immune parameters were affected at lower dose levels than developmental parameters. ► Findings demonstrate the susceptibility of the

    Preclinical research demonstrates that cannabinoids have differing effects in adolescent and adult animals. Whether these findings translate to humans has not yet been investigated. Here we believe we conducted the first study to compare the acute effects of cannabis in human adolescent (n=20; 16–17 years old) and adult (n=20; 24–28 years old) male cannabis users, in a placebo-controlled, double-blind cross-over design. After inhaling vaporized active or placebo cannabis, participants completed tasks assessing spatial working memory, episodic memory and response inhibition, alongside measures of blood pressure and heart rate, psychotomimetic symptoms and subjective drug effects (for example, ‘stoned', ‘want to have cannabis'). Results showed that on active cannabis, adolescents felt less stoned and reported fewer psychotomimetic symptoms than adults. Further, adults but not adolescents were more anxious and less alert during the active cannabis session (both pre- and post-drug administration). Following cannabis, cognitive impairment (reaction time on spatial working memory and prose recall following a delay) was greater in adults than adolescents. By contrast, cannabis impaired response inhibition accuracy in adolescents but not in adults. Moreover, following drug administration, the adolescents did not show satiety; instead they wanted more cannabis regardless of whether they had taken active or placebo cannabis, while the opposite was seen for adults. These contrasting profiles of adolescent resilience (blunted subjective, memory, physiological and psychotomimetic effects) and vulnerability (lack of satiety, impaired inhibitory processes) show some degree of translation from preclinical findings, and may contribute to escalated cannabis use by human adolescents.

    In this study, a spectrographic analysis was designed to improve the description of the shape, the modulations, the rate, length and frequencies of BALB/c mouse calls in different behavioural situations. Male and female calls emitted during investigation of cages with clean bedding, soiled with male or female bedding, and during same-sex encounters, were recorded and described. BALB/c male mice uttered different types of vocalisations both when investigating counterpart odour cues and when interacting with same-sex counterparts. BALB/c female mice vocalised solely during same-sex counterpart encounters and it appeared that calls were uttered mainly by the resident females. Male and female mice present a complex array of calls, which seem to be linked to particular behavioural situations. Further studies using this technology may help to improve our understanding of the role of vocal communication in natural rodent populations.

    Manganese chloride (MnCl2) is capable of stimulating luteinizing hormone releasing hormone (LHRH) secretion in adult male Sprague-Dawley rats through the activation of the hypothalamic nitric oxide/cyclic guanosine monophosphate (cGMP)/protein kinase G pathway. The present study aimed to determine the involvement of specific neurotransmitters involved in this action. Our results indicate that dopamine, but not glutamic acid and prostaglandinds, mediates the MnCl2 stimulated secretion of LHRH from medial basal hypothalami in vitro, as well as increases the activity of nitric oxide synthase. Furthermore, a biphasic response was observed in that gamma aminobutyric acid (GABA) release was also increased, which acts to attenuate the MnCl2 action to stimulate LHRH secretion. Although it is clear that manganese (Mn+2) can acutely induce LHRH secretion in adult males, we suggest that the additional action of MnCl2 to release GABA, a LHRH inhibitor, may ultimately contribute to suppressed reproductive function observed in adult animals following exposure to high chromic levels of Mn+2.

    The course of male development of implicit gender attitudes between young age (N = 30, age 17-26 years) and old age (N = 34, age 56-78 years) was investigated. The findings demonstrated that younger males had a stronger implicit preference for females relative to males than did older participants, shedding light on the nature of age differences in gender attitudes in regard to implicit measures. Although younger and older participants demonstrated different levels of gender bias on an implicit association test (IAT), the application of the ReAL model [Meissner, F., & Rothermund, K. (2013). Estimating the contributions of associations and recoding in the implicit association test: The ReAL model for the IAT. Journal of Personality and Social Psychology, 104(1), 45-69.] showed that evaluative associations of both female and male were activated at equivalent levels among both the young and old age groups, but younger males were more able to recode the female gender and a positive evaluation into common categories. Thus, the differences in attitudinal responses between younger and older males exaggerated the differences in the underlying evaluative associations with respect to gender and concealed the differences in recoding processes. These findings have important implications for the measurement and interpretation of implicit gender attitudes.

    Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

    A general legal definition of rape is sexual intercourse forced on an individual by another against his/her will and overcoming his/her resistance. Although the female is usually referred to as the survivor and the male as the perpetrator, there are cases of male rape. Rape may be divided into stranger rape and acquaintance rape. Types of…

    The present study explored the influence of survivor weight and participant gender, rape myth acceptance, and antifat attitudes on perceptions of sexual assault. Using an online survey tool, a community sample of 413 adult Canadian residents reviewed a hypothetical sexual assault scenario and completed a series of evaluations and attitudinal questionnaires. Generalized linear model analyses revealed that participa
