Paradoxical effects of sublethal exposure to the naturally derived insecticide spinosad in the dengue vector mosquito, Aedes aegypti

PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 3 2009
Gloria E Antonio
Abstract BACKGROUND: Recent studies have indicated that spinosad, a mixture of two tetracyclic macrolide compounds produced during the fermentation of a soil actinomycete, may be suitable for controlling a number of medically important mosquito species, including the dengue vector, Aedes aegypti L. The authors determined the effects of a 1 h exposure to a 50% lethal concentration (LC50) of spinosad in the larval stage on the wing length, longevity and reproductive capacity of the adult survivors. RESULTS: The LC50 of spinosad for a wild-caught population of Ae. aegypti from Chiapas, southern Mexico, was estimated to be 0.06 mg AI L,1 in late third instars. Paradoxically, the female survivors of exposure to this concentration were significantly larger (as determined by wing length) laid more eggs, but were slightly less fertile than control females. This was probably due to elimination of the smaller and more susceptible fraction of mosquito larvae from the experimental population following spinosad treatment. Male survivors, in contrast, were significantly smaller than controls. No significant differences were detected in the adult longevity of treated and control insects of either sex. CONCLUSIONS: The increase in reproductive capacity of spinosad-treated females did not compensate for mortality in the larval stage and would be unlikely to result in population increase in this mosquito under the conditions that were employed. Sustained-release formulations would likely assist in minimizing the occurrence of sublethal concentrations of this naturally derived product in mosquito breeding sites.

The Legacy of Childhood Sexual Abuse and Family Adversity

JOURNAL OF NURSING SCHOLARSHIP, Issue 4 2008

Purpose: To describe the process by which childhood adversity influences the life course of survivors of childhood sexual abuse. Design: A community-based, qualitative, grounded-theory design. Methods: In this grounded theory study, data were drawn from open-ended interviews conducted as part of a larger study of women's and men's responses to sexual violence. The current study indicates the experiences of 48 female and 40 male survivors of childhood sexual abuse and family adversity. Data were analyzed using the constant comparison method. Findings: Participants described a sense of inheriting a life of abuse and adversity. The process by which childhood adversity influences the life course of adult survivors of childhood sexual abuse is labeled Living the Family Legacy. The theory representing the process of Living the Family Legacy includes three major life patterns: (a) being stuck in the family legacy, (b) being plagued by the family legacy, and (c) rejecting the family legacy/creating a new one. Associated with these life patterns are three processes by which participants passed on a legacy to others, often their children: (a) passing on the family legacy, (b) taking a stab at passing on a new legacy, and (c) passing on a new legacy. Conclusions: The legacy of abuse and adversity has a profound effect on the lives of survivors of childhood sexual abuse. There are several trajectories by which the influence of childhood adversity unfolds in the lives of adult survivors and by which the legacy is passed on to others. Clinical Relevance: The model representing the theoretical process of Living the Family Legacy can be used by clinicians who work with survivors of childhood sexual abuse and childhood adversity, especially those who have parenting concerns.

Sexual functioning in young adult survivors of childhood cancer

PSYCHO-ONCOLOGY, Issue 8 2010
Brad J. Zebrack
Abstract 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. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Cancer screening practices of adult survivors of retinoblastoma at risk of second cancers

CANCER, Issue 2 2008
Victoria Sheen BA
Abstract BACKGROUND. The aim of the current study was to investigate the pattern of cancer screening behavior in adult retinoblastoma survivors, who are at high risk of developing second cancers. METHODS. Self-reported cancer screening practices were investigated in a cohort of retinoblastoma survivors to evaluate whether they were receiving adequate screening for specific cancers and compare these rates with those of other adult survivors of childhood cancer and the general population. The prevalence of breast self-examination, clinical breast examination, mammography, Papanicolaou (Pap) test, testicular self-examination, and magnetic resonance imaging (MRI) or computed tomography (CT) scanning was determined from computer-aided telephone interviews with 836 retinoblastoma survivors aged >18 years. RESULTS. Among female survivors, 87% had a Pap test within the past 2 years, and 76% of females age >40 years reported having a mammogram within the past 2 years; 17.4% of male survivors had performed monthly testicular self-examinations. A significantly higher proportion of hereditary compared with nonhereditary survivors reported having undergone an MRI or CT scan in the past 5 years. Higher education, greater contact with the medical care system, and having a second cancer were found to be associated positively with most screening practices. Cancer screening practices reported by retinoblastoma survivors were similar to national screening rates for breast, cervical, and testicular cancer. CONCLUSIONS. To the authors' knowledge, the current study provides the first report of cancer screening practices of retinoblastoma survivors. Survivors of hereditary retinoblastoma should be encouraged to maintain, if not increase, their current screening practices to ensure early detection of second cancers in this high-risk population.

Symptomatic hypogonadism in male survivors of cancer with chronic exposure to opioids

CANCER, Issue 4 2004
Arun Rajagopal M.D.
Abstract BACKGROUND Profound hypogonadism has been noted in patients receiving intrathecal opioids. The purpose of the current study was to determine whether chronic consumption of oral opioids by male survivors of cancer also would lead to central hypogonadism and whether this hypogonadism was associated with symptoms of sexual dysfunction, fatigue, anxiety, and depression. METHODS A case,control study was conducted at The University of Texas M. D. Anderson Cancer Center (Houston, TX), in which 20 patients who were chronically consuming opioids were compared with 20 matched controls. Patients completed the Sexual Desire Inventory (SDI), the Hospital Anxiety and Depression Scale (HADS), the Functional Assessment of Chronic Illness Therapy with general and fatigue subscales (FACT-G/FACIT-F), and the Edmonton Symptom Assessment System (ESAS) questionnaires. Serum samples were collected for testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). RESULTS Comparing the opioid group with the control group, 18 of the 20 patients (90%; 95% confidence interval [CI], 65,98%) exhibited hypogonadism, compared with 8 of the 20 control patients (40%; 95% CI, 19,64%). The median testosterone level was 145 ng/dL versus 399.5 ng/dL (5.0 nmol/L vs. 13.9 nmol/L; P < 0.0001), the median FSH level was 2.85 milli,International Units (mIU)/mL versus 5.3 mIU/mL (P = 0.08), the median LH level was 1.8 mIU/mL versus 4.2 mIU/mL (P = 0.0014), the median SDI-dyadic score was 18.5 versus 40 (P = 0.01), the median SDI-solitary score was 0 versus 5 (P = 0.007), the HADS (anxiety) score was 8.5 versus 5.5 (P = 0.053), the HADS (depression) score was 7.5 versus 1.5 (P = 0.0002), the FACT-G score was 64 versus 96.3 (P = 0.0001), and the FACIT-F score was 24 versus 46 (P = 0.0003). CONCLUSIONS Survivors of cancer who chronically consumed opioids experienced symptomatic hypogonadism with significantly higher levels of depression, fatigue, and sexual dysfunction. With the increasing use of opioids among patients with cancer, further research in improving quality-of-life outcomes is warranted. Cancer 2004;100:851,8. © 2004 American Cancer Society. [source]
