    Childhood sexual abuse has been consistently associated with suicidal behavior. We studied suicide attempt features in depressed individuals sexually abused as children. On average, sexual abuse started before age 9. It frequently coexisted with physical abuse. Suicide attempters more often had personality disorders and had endured abuse for longer, but did not differ in terms of other clinical characteristics from non-attempters. Earlier onset of sexual abuse and its duration were associated with more suicide attempts. However, when personality disorders were included in the regression model, only these disorders predicted number of attempts. The severity of sexual abuse and the coexistence of physical abuse were correlated with age at first suicide attempt. However, only severity of sexual abuse was marginally associated with age at first suicide attempt in the regression model. Finally, the earlier the age of onset of sexual abuse, the higher the intent, even after controlling for age, sex and personality disorders. This suggests that the characteristics of childhood sexual abuse, especially age of onset, should be considered when studying the risk for suicidal behavior in abused populations. PMID:23737424

    Background Trauma is among the main death causes and morbidity in the world and is often related to the use of alcohol and its abuse has reached massive proportions, no matter if the country is developed or not, being considered as public health problem. Since there are very few randomized and prospective studies in literature about the association of facial trauma and the use of alcohol, this study aims to investigate the impact of alcohol use in facial trauma. Material and Methods This was a prospective and cross sectional study, involving facial trauma patients attended at Oral Maxillofacial Surgery Division of a State Hospital. Variables included patient´s profile, trauma etiology, facial region involved, type of injury and treatment and days of hospitalization. AUDIT test was applied to identify risks and damages of alcohol use and chemical dependence. Absolute distribution, uni and mutilvaried percentages were made for data evaluation. Pearson´s qui-squared and Fisher´s Exact tests were also used. Results One hundred patients were evaluated. The patient´s mean age was 33.50 years-old, 48% had between 17 and 29 years old, 28% had 30 to 39, and 24% 40 or more. Most of them were male (86%). The most frequent etiology was traffic accident (57%), the extraoral area was most committed (62%), the most frequent type of injury was fractures (78%) and the most affected bone was the mandible (36%). More than half of the patients (53%) had surgical treatment. 38% had their discharge from hospital right after the first attendance. The AUDIT most frequent answer was “moderate use” (46%) and use at risk (39%). There was significant difference between the use of alcohol (AUDIT) and hematoma (0.003) and number of days of hospitalization (p=0.005). Conclusions In this study it was not observed association between alcohol consumption using the AUDIT and trauma etiology, but patient victims of traffic accidents were classified as with risk in the scale.

    Objective: To examine the extent to which abused and neglected children perpetrate three different types of violence within and outside the home: criminal, child abuse, and intimate partner violence and determine whether childhood maltreatment leads to an increased risk for poly-violence perpetration. Method: Using data from a prospective cohort design study, children (ages 0-11) with documented histories of physical and sexual abuse and/or neglect (n = 676) were matched with children without such histories (n = 520) and assessed in young adulthood (average age 29). Official criminal records in conjunction with self-report data were used to assess violent outcomes. Results: Compared to the control group, individuals with histories of child abuse and/or neglect were significantly more likely to be poly-violence perpetrators, perpetrating violence in all three domains (relative risk = 1.26). All forms of childhood maltreatment (physical and sexual abuse and neglect) significantly predicted poly-violence perpetration. Conclusions: These findings expand the cycle of violence literature by combining the distinct literatures on criminal violence, child abuse, and partner violence to call attention to the phenomenon of poly-violence perpetration by maltreated children. Future research should examine the characteristics of maltreated children who become poly-violence perpetrators and mechanisms that lead to these outcomes. PMID:26191459

  9. Inhaled vs. oral alprazolam: subjective, behavioral and cognitive effects, and modestly increased abuse potential

    Rationale Infrahuman and human studies suggest that a determinant of the abuse potential of a drug is rate of onset of subjective effects. Objectives This study sought to determine if the rate of onset of subjective effects and abuse potential of alprazolam would be increased when administered via inhalation vs. the oral route. Methods Placebo, inhaled alprazolam (0.5, 1, 2 mg), and oral alprazolam (1, 2, 4 mg) were administered under double-blind, double-dummy conditions using a cross-over design in 14 healthy participants with histories of drug abuse. Participant and observer ratings, and behavioral and cognitive performance measures were assessed repeatedly during 9 hour sessions. Results Both routes of administration produced orderly dose and time-related effects, with higher doses producing greater and longer lasting effects. Onset of subjective effects following inhaled alprazolam was very rapid (e.g., 2 vs. 49 minutes after 2 mg inhaled vs. oral). On measures of abuse potential (e.g., liking and good effects), inhaled alprazolam was more potent, as evidenced by a leftward shift in the dose response curve. Despite the potency difference, at the highest doses, peak ratings of subjective effects related to abuse potential (e.g., “drug liking”) were similar across the two routes. On other measures (e.g., sedation and performance) the routes were equipotent. Conclusions The inhaled route of administration modestly increased the abuse potential of alprazolam despite significantly increasing its rate of onset. If marketed, the reduced availability and increased cost of inhaled alprazolam may render the societal risk of increased abuse to be low. PMID:25199955

    The prevalence, incidence, and impact of the gender-based abuse (GBA) of college women have been increasingly documented since the 1980s, with growing precision in the measurements and expanding identification of tactics. Although there is an obvious class bias in focusing on college women (compared to women of similar ages not attending college), it is important to address GBA among this population as they are at serious risk of sexual abuse (particularly incapacitated rape), intimate partner abuse (IPA), and stalking. This article addresses the stealth nature of the nonviolent GBAs of college women and how these abuses frequently operate under the radar of acknowledgment by society, the abusers, campus officials, the criminal legal system, and sometimes, the survivors.

    Serious infection is a recognized complication of intravenous drug abuse and a major cause of morbidity and mortality among intravenous drug users. Trends in rates of serious infection and the associated costs related to opioid abuse/dependence have not been previously investigated in the context of the US opioid use epidemic. Our study, using a nationally representative sample of US inpatient hospitalizations, showed that hospitalizations related to opioid abuse/dependence both with and without associated serious infection significantly increased from 2002 to 2012, respectively, from 301,707 to 520,275 and from 3,421 to 6,535. Additionally, inpatient charges for both types of hospitalizations almost quadrupled over the same time period, reaching almost $15 billion for hospitalizations related to opioid abuse/dependence and more than $700 million for those related to associated infection in 2012. Medicaid was the most common primary payer for both types of hospitalizations. Our results characterize the financial burden on the health care system related to opioid abuse/dependence and one of the more serious downstream complications of this epidemic: serious infection. These findings have important implications for the hospitals and government agencies that disproportionately shoulder these costs and for clinicians, researchers, and policy makers interested in estimating the potential impact of targeted public health interventions on a national level.

    This investigation evaluated an experimental protocol employed by nurses with parents to increase access to evidence-based mental health treatment for children who are suspected victims of abuse. The protocol was compared with typical services during forensic medical examinations, first in a quasi-experimental design, then as a randomized controlled trial. In both studies, the protocol produced a significant increase in parental reports of having discussed evidence-based treatment during a mental health appointment within 1 month after the forensic medical examination. Likewise, both studies showed that the protocol produced a significant increase in parent-reported satisfaction with the forensic medical examination. Similarly, nurses viewed the protocol favorably. These findings suggest that this approach may be sustainable as a standard component of forensic medical examinations for children who are suspected victims of abuse. PMID:18359928

    Clinicians have long recognized and attorneys have disputed that physical evidence of injury, sexually transmitted diseases, and seminal fluid are often absent in cases of child sexual abuse. To determine the frequency and significance of physical evidence in legally "proven" felony cases with penetration, a retrospective review of sexual abuse court records was done. A total of 45 randomly selected cases were reviewed; 39 (87%) had resulted in conviction of the perpetrator for felony. Charges of vaginal rape were made in 32 cases, and charges of oral and/or anal sodomy in 23 cases. No significant difference in rate of felony conviction was found in cases with or without physical evidence. Of 32 cases without physical evidence, 30 (94%) resulted in felony convictions, whereas only 9 of 13 cases (69%) with physical evidence resulted in a felony conviction. Multiple variables describing the abuse situation were not shown to effect the legal outcome of the cases. Of cases that resulted in felony convictions, physical evidence was present in only 23% (9 of 39). These results should be helpful for the clinician in counseling the family of the sexual abuse victim and the attorney who prosecutes child sexual abuse cases. PMID:2587130

  15. Do Child Abuse and Maltreatment Increase Risk of Schizophrenia?

    Sideli, Lucia; Mule, Alice; La Barbera, Daniele

    2012-01-01

    Introduction IntroductionaaAlthough childhood abuse is a recognised risk factor for depression, post-traumatic stress disorder, and substance misuse, its role in the aetiology of psychotic disorder remained controversial. This is in part because the putative effect of childhood trauma on psychosis has been mostly evaluated by small, cross sectional, uncontrolled studies that raised methodological issues. Methods Papers concerning the association between childhood trauma and psychotic disorders (to November, 2011) were identified using a comprehensive search of PubMed, Psychinfo, and Scopus and analysing reference list of relevant papers. A narrative synthesis was used to summarise results. Results An association between childhood abuse and psychotic symptoms was consistently reported by large cross sectional surveys with an effect ranging from 1.7 to 15. However, we cannot conclude that the relationship is causal as lack of longitudinal studies prevent us from fully excluding alternative explanations such as reverse causality. Gender, cannabis use, and depressive and post-traumatic stress disorder symptoms appear to moderate the effect of childhood trauma on psychotic disorders. However, specificity of childhood abuse in psychotic disorders and, particularly, in schizophrenia has not been demonstrated. Conclusion Although the association between childhood abuse and psychosis has been replicated, the etiological role of such early adversity has yet to be fully clarified. So far none of the studies reported support the hypothesis that childhood abuse is either sufficient or necessary to develop a psychotic disorder. It seems likely that any effect of childhood abuse on schizophrenia needs to be understood in terms of genetic susceptibility and interaction with other environmental risk factors. PMID:22707958

    Background Hypothalamic–pituitary–adrenal (HPA) axis activity is known to be altered following events such as childhood abuse. However, despite potential adverse consequences for the offspring of women who have experienced abuse, very little is known about altered HPA axis activity during pregnancy. Methods During pregnancy, 180 women from diverse racial/ethnic backgrounds reported on their exposure to emotional, physical and/or sexual abuse before the age of 11, and general post-traumatic stress symptoms (ie, not limited to childhood years or abuse experiences). Around delivery, they provided hair samples for the assessment of cortisol levels during pregnancy. Hair cortisol was assessed for each pregnancy trimester. The effect of childhood abuse on hair cortisol was assessed using mixed-effects analyses of covariance models allowing for within-subject correlated observations, and were first performed in the entire sample and subsequently stratified by race/ethnicity. Results Controlling for post-traumatic stress symptoms, hair cortisol levels varied by history of child abuse, F(2,166)=3.66, p=0.028. Childhood physical and/or sexual abuse was associated with greater hair cortisol levels, t(166)=2.65, p=0.009, compared with no history of abuse. Because childhood rates of abuse and hair cortisol levels varied by race/ethnicity, analyses were stratified by race/ethnicity. The associations between history of abuse and cortisol levels were only significant among black women, F(2,23)=5.37, p=0.012. Conclusions Childhood abuse, especially physical and/or sexual abuse, is associated with differences in cortisol production during pregnancy, particularly among black women. Future research should investigate how these differences impact physical and mental health outcomes among offspring of affected women. PMID:26219886

  20. Significance, Nature, and Direction of the Association Between Child Sexual Abuse and Conduct Disorder: A Systematic Review.

    2015-07-01

    To elucidate the significance, nature, and direction of the potential relationship between child sexual abuse and conduct disorder, all the pertinent studies were reviewed. Ten databases were searched. Blind assessments of study eligibility and quality were performed by two independent researchers. Thirty-six studies including 185,358 participants and meeting minimum quality criteria that were enough to ensure objectivity and to not invalidate results were analyzed. Across the majority of studies, conduct disorder was significantly and directly related to child sexual abuse, especially repeated sexual molestation and abuse involving penetration, even after controlling for various sociodemographic, family, and clinical variables. The association between child sexual abuse and conduct disorder was not confounded by other risk factors, such as gender, socioeconomic status, school achievement, substance problems, physical abuse, parental antisocial behavior or substance problems, parent-child relationships, and family disruption, conflict, or violence. Evidence for a significant interactive effect between child sexual abuse and monoamine oxidase A gene on conduct disorder was scant. Early sexual abuse might predispose to the subsequent onset of conduct disorder which, in turn, may lead to further sexual victimization through association with sexually abusive peers or involvement in dangerous situations or sexual survival strategies.

  1. Dopamine increases in striatum do not elicit craving in cocaine abusers unless they are coupled with cocaine cues.

    Imaging studies have shown an association between dopamine increases in striatum and cue induced craving in cocaine abusers. However, the extent to which dopamine increases reflect a primary rather than a secondary response to the cues remains unclear. Here we evaluated the extent to which dopamine increases by themselves can induce craving in cocaine abusers. Using PET and [(11)C]raclopride (D2 receptor radioligand sensitive to competition with endogenous dopamine) we show that in cocaine abusers (n=20) oral methylphenidate (20 mg), which significantly increased dopamine in striatum, did not induce craving unless subjects were concomitantly exposed to cocaine cues (video scenes of subjects self-administering cocaine). This suggests that dopamine increases associated with conditioned cues are not primary responses but reflect downstream stimulation of dopamine cells (presumably glutamatergic afferents from prefrontal cortex and/or amygdala). Inasmuch as afferent stimulation of dopamine neurons results in phasic cell firing these findings suggest that "fast" dopamine increases, in contrast to the "slow" dopamine increases as achieved when using oral methylphenidate (mimicking tonic dopamine cell firing), are required for cues to trigger craving. The fact that methylphenidate induced craving only when given with the cocaine cues highlights the context dependency of methylphenidate's effects and suggests that its use for the treatment of ADHD subjects with co-morbid drug abuse should not increase craving.

    Objectives This study tested the hypothesis that women exposed to childhood abuse or neglect would have an increased likelihood of reporting hot flashes and night sweats during the menopausal transition. Design This hypothesis was evaluated in 332 white and African American women participating in the Study of Women’s Health Across the Nation Mental Health Study, a prospective investigation of women transitioning through menopause. Childhood abuse and neglect were measured once with the Child Trauma Questionnaire. Vasomotor symptoms (any/none hot flashes, night sweats) were reported annually over 8 years. Associations between maltreatment and vasomotor symptoms were estimated with generalized estimating equations. Results Childhood abuse or neglect was associated with increased reporting of hot flashes (odds ratio = 1.73, 95% CI: 1.23–2.43) and night sweats (odds ratio = 1.75, 95% CI: 1.26–2.43) in age-adjusted models. Results persisted in multivariable models and across several types of abuse and neglect. Conclusions The experience of childhood abuse and neglect is associated with increased vasomotor symptom reporting in adulthood. The sequelae of childhood abuse and neglect may persist well into adulthood to influence the occurrence of vasomotor symptoms at midlife. PMID:18257140

    The number of police reports on child assault shows an increasing trend during the last two decades in Sweden. The purpose of this article is to present possible explanations. Increased awareness of child abuse, legislative reforms, changes in attitudes toward corporal punishment and violence in general, and changed routines within schools can explain the increasing trend in police reporting. An actual increase in the rate of child abuse is possible but less likely. Reports of increasingly violent behavior among young people must be taken seriously. PMID:11402983

    Few interventions have targeted perceived stress as a co-occurring construct central to substance use and subsequent HIV/AIDS risk reduction among African American urban young adults. The Color It Real Program was a seven session, weekly administered age-specific and culturally-tailored intervention designed to provide substance abuse and HIV education and reduce perceived stress among African Americans ages 18 to 24 in Atlanta, GA. Effectiveness was assessed through a quasi-experimental study design that consisted of intervention (n = 122) and comparison (n = 70) groups completing a pre- and post-intervention survey. A series of Analysis of Variance (ANOVA) tests were used to assess pre- to post-intervention changes between study groups. For intervention participants, perceived stress levels were significantly reduced by the end of the intervention (t(70) = 2.38, p = 0.020), condom use at last sexual encounter significantly increased (F = 4.43, p = 0.0360), intervention participants were significantly less likely to drink five or more alcoholic drinks in one sitting (F = 5.10, p = 0.0245), and to use clean needles when injecting the drug (F = 36.99, p = 0.0001). This study is among the first of its kind to incorporate stress management as an integral approach to HIV/SA prevention. The program has implications for the design of other community-based, holistic approaches to addressing substance use and risky behaviors for young adults. PMID:26703653

    Increasing numbers of dengue fever (DF) cases reflect the increasing travel mobility together with the expanding geographical distribution of the vector Aedes aegypti. Compared with earlier surveys in Germany, higher incidences occur and correlate well with ongoing outbreaks. Therefore, we investigated 767 serum samples from 594 returning travellers with suspected DF between 2005 and 2010, which where sent from different hospitals in the drainage area Frankfurt/Main. Established diagnostic assays were ELISA, immunofluorescence and chromatographic tests. We obtained 112 dengue-seropositive serum samples from totally 60 patients: the detection rate was 10.1% (60 out of 594). A significant increase was found in 2010. Most patients were aged between 40 and 49, and indirect immunofluorescence technique indicated mainly DF serotype 2. Actual data reveal a significant rise in imported DF cases in 2010 according to an increasing risk to acquire DF virus infection. Nevertheless, dengue haemorrhagic fever and dengue shock syndrome are still rare in travellers, but those with a history of dengue should be tested for DF serotypes and advised to protect themselves well from mosquitoes when travelling to endemic areas.

    Upon exposure to microgravity, astronauts lose up to 10% of their total plasma volume, which may contribute to orthostatic intolerance after space flight. Because plasma colloid osmotic pressure (COP) is a primary factor maintaining plasma volume, our objective was to measure time course changes in COP during microgravity simulated by 6 deg. head-down tilt (HDT). Seven healthy male subjects (30-55 years of age) were placed in HDT for 16 days. For the purpose of another study, three of the seven subjects were chosen to exercise on a cycle ergometer on day 16. Blood samples were drawn immediately before bedrest on day 14 of bedrest, 18-24 hours following exercise while all subjects were still in HDT and 1 hour following bedrest termination. Plasma COP was measured in all 20 microliter EDTA-treated samples using an osmometer fitted with a PM 30 membrane. Data were analyzed with paired and unpaired t-tests. Plasma COP on day 14 of bedrest (29.9 +/- 0.69 mmHg) was significantly higher (p less than 0.005) than the control, pre-bedrest value (23.1 +/- 0.76 mmHg). At one hour of upright recovery after HDT, plasma COP remained significantly elevated (exercise: 26.9 +/- 0.87 mmHg; no exercise: 26.3 +/- 0.85 mmHg). Additionally, exercise had no significant effect on plasma COP 18-24 hours following exercise (exercise: 27.8 +/- 1.09 mmHg; no exercise: 27.1 +/- 0.78 mmHg). Our results demonstrate that plasma COP increases significantly with microgravity simulated by HDT. However, preliminary results indicate exercise during HDT does not significantly affect plasma COP.

    ), will result in a measurable decrease (~0.6ppm) in the seasonal CO2 minimum. This holds regardless of whether the sink is the result of 1) An increase in NPP, or 2) The combined effect of a temperature-driven decrease in heterotrophic respiration (Rh) and no change in NPP. This is since both NPP and Rh peak in summer. By contrast, observations from the NOAA global CO2 monitoring network show the opposite change in the seasonal minimum in 1992 and 1993 (~0.2ppm increase) both at Mauna Loa, and in the Marine Boundary Layer mean (>20° N), which is hard to reconcile with increased NPP in northern summer. Another indicator of annual NPP is tree wood increment. Previous work (Krakauer et al., 2003) showed that the average response in tree ring series after past Pinatubo-size volcanic eruptions implied lower NPP north of 45° N, presumably as a result of shorter growing season and lower total irradiance induced by scattering aerosols, and no significant change in NPP at lower latitudes. Here we show that In 1992, after the Pinatubo eruption, ring width in the 25° N-45° N band was 99.3±2.9% of average (n=351 sites), similar to the average of 100.4±2.2% over past eruptions (n=15 eruptions) (Uncertainty is given as 2 SE.). These results are also inconsistent with substantial NPP enhancement, although a limitation of the tree-ring approach is that available measurements do not uniformly sample the latitude band. The combined evidence of tree rings and the CO2 seasonal cycle shows that the enhancement of NPP by scattering aerosols on annual timescales is weak. This result suggests that reducing aerosols through stricter pollution controls may strengthen the land carbon sink, while geo-engineering schemes which aim to mitigate global warming by spreading scattering aerosols in the stratosphere may weaken it.

    Correlative human observational studies on substances of abuse have been highly dependent on the use of rodent models to determine the neuronal and molecular mechanisms that control behavioral outcomes. This is particularly true for gestational exposure to non-illicit substances of abuse, such as excessive dietary fat, ethanol, and nicotine, which are commonly consumed in our society. Exposure to these substances during the prenatal period has been shown in offspring to increase their intake of these substances, induce other behavioral changes, and affect neurochemical systems in several brain areas that are known to control behavior. More importantly, emerging studies are linking the function of the immune system to these neurochemicals and ingestion of these abused substances. This review article will summarize the prenatal rodent models used to study developmental changes in offspring caused by prenatal exposure to dietary fat, ethanol, or nicotine. We will discuss the various techniques used for the administration of these substances into rodents and summarize the published outcomes induced by prenatal exposure to these substances. Finally, this review will cover some of the recent evidence for the role of immune factors in causing these behavioral and neuronal changes. PMID:27148536

    Abusive supervision, a type of interpersonal mistreatment from direct supervisors toward subordinates, has received growing attention in leadership research. However, the role of narcissism related to abusive supervision is still unclear. The purpose of this study was to investigate the associations of narcissism with subordinates' perceptions of abusive supervision and deviance toward the supervisor. Ratings on the aforementioned variables were collected from 403 full-time employees at two different times with one week in between (95 men, 308 women; M age = 26.0 yr.; M tenure = 5.1 yr.). The results of regression analyses showed that narcissism was significantly and negatively related to abusive supervision. Moreover, narcissism moderated the positive relationship between abusive supervision and deviance toward the supervisor. PMID:25243364

    Objective Exposure to parental verbal aggression (PVA) during childhood increases risk for the development of psychopathology, particularly mood and anxiety disorders. Other forms of childhood abuse have been found to be associated with alterations in brain structure. The aim of this study was to ascertain whether exposure to PVA was associated with discernible effects on brain morphology. Methods Optimized voxel based morphometry was performed on 21 unmedicated, right-handed subjects (18–25 years) with histories of PVA and 19 psychiatrically healthy controls of comparable age and gender. Group differences in gray matter volume (GMV) – covaried by age, gender, parental education, financial stress, and total GMV – were assessed using high-resolution, T1-weighted, volumetric MRI data sets (Siemens 3T trio scanner). Results GMV was increased by 14.1% in the left superior temporal gyrus (STG, BA 22) (P = 0.004, corrected cluster level). GMV in this cluster was associated most strongly with levels of maternal (β = 0.544, P < 0.0001) and paternal (β = 0.300, P < 0.02) verbal aggression and inversely associated with parental education (β = −0.577, P < 0.0001). Conclusion Previous studies have demonstrated an increase in STG GMV in children with abuse histories, and found a reduction in fractional anisotropy in the arcuate fasciculus connecting Wernicke’s and frontal areas in young adults exposed to PVA. These findings and the present results suggest that the development of auditory association cortex involved in language processing may be affected by exposure to early stress and/or emotionally-abusive language.

    Peak activity over the spleen as a percentage of peak activity over the liver was measured in 265 99mTechnetium sulphur colloid liver scintiscans. The value exceeded 70% in 50 cases. In 32 of these cirrhosis was present; the other 18 scans were from patients with a wide variety of conditions, including secondary deposits, hepatitis, and diseases involving the reticuloendothelial system. A measure of the total activity in the spleen was derived from the peak activity and the length of the spleen. In cirrhosis this was closely related to the finding of oesophageal varices thus showing the importance of a collateral circulation (which allows colloid to bypass the liver) in the increased uptake of colloid by the spleen. In eight patients with hepatosplenomegaly due to blood dyscrasia or disease involving the reticuloendothelial system, total activities in the liver and spleen were estimated from the anteroposterior colour dot scan, and both liver and spleen blood flow were measured by methods independent of reticuloendothelial cell function. The results showed that the main factor causing increased uptake of colloid by the spleen in these diseases was an increased blood flow in the spleen relative to that in the liver.

    β-glucosidase A (bglA) in Clostridium thermocellum 27405 was increased by expression from shuttle vector pIBglA in attempts to increase cellulase activity and ethanol titer by lowering the end product inhibition of cellulase. Through a modified electrotransformation protocol C. thermocellum transformant (+MCbglA) harbouring pIBglA was produced. The β-glucosidase activity of +MCbglA was 2.3- and 1.6-fold greater than wild-type (WT) during late log and stationary phases of growth. Similarly, total cellulase activity of +MCbglA was shown to be 1.7-, 2.3- and 1.6-fold greater than WT during, log, late log and stationary phases of growth. However, there was no significant correlation found between increased cellulase activity and increased ethanol titers for +MCbglA compared with the WT. C. thermocellum has industrial potential for consolidated bioprocessing (CBP) to make a more cost effective production of biofuels; however, the hydrolysis rate of the strain is still hindered by end product inhibition. We successfully increased total cellulase activity by increased expression of bglA and thereby increased the productivity of C. thermocellum during the hydrolysis stage in CBP. Our work also lends insights into the complex metabolism of C. thermocellum for future improvement of this strain. PMID:22922214

  20. Heterogeneity of aquatic sediment significantly increases nitrogen removal

    Sawyer, A. H.

    2014-12-01

    In recent decades, nitrate loads to rivers and coasts have increased dramatically and contributed to eutrophication and hypoxia in coastal waters. A major sink for nitrate in the environment is denitrification in aquatic sediments. Here, I show that nitrate removal rates are as much as 100 times more efficient in heterogeneous than equivalent homogeneous aquatic sediments. Numerical experiments quantify nitrate removal from groundwater discharging through shallow columns of heterogeneous aquatic sediment. The steady groundwater flow equation was coupled to the advection-dispersion-reaction equations for dissolved oxygen, nitrate, and dissolved organic carbon (DOC). Bimodal sediments composed of sand and clay were simulated using TPROGS for a wide range of clay fractions. Small (centimeter-scale) sedimentary structures were intended to represent infilled burrows or clay rip-up clasts. Clay structures were assigned a relatively high organic carbon content (2%). The local source of DOC fuels oxygen consumption in clay structures and promotes restricted zones of denitrification in otherwise aerobic sediments. As a result, redox transformations do not strictly depend on residence times but rather on distributions of organic carbon in aquatic sediments. Furthermore, bimodal sand and clay deposits are more efficient than either clean sand or homogeneous sandy-clay at removing nitrate. These results help explain observations of efficient nitrate removal in relatively sandy, oxygenated aquatic sediments when small organic-rich structures are present. The results also suggest that models of reactive transport in homogeneous sediment underestimate biogeochemical transformation rates relative to heterogeneous sediment. Similarly, laboratory-derived denitrification rates on homogenized cores are likely underestimated relative to intact cores.

    Objective: Abuse is considered to have a place in the etiology of various psychiatric disorders. Premenstrual dysphoric disorder (PMDD) is one of the psychiatric disorders for which abuse could be an etiologic factor; however, few studies have investigated the relationship between abuse and PMDD. In this study, our aim was to investigate childhood abuse in patients with PMDD and compare them with healthy female subjects. Method: This cross-sectional study included 70 women with PMDD (DSM-IV-TR criteria) who were admitted to the outpatient psychiatry clinic of Ankara Yenimahalle State Hospital, Ankara, Turkey, between December 2012 and December 2013. Additionally, 78 healthy controls were included in the study. Sociodemographic, familial, and reproductive period characteristics of the women were recorded. All subjects were administered the Premenstrual Syndrome Scale (PMSS) and the Childhood Trauma Questionnaire (CTQ). Results: Among the sociodemographic characteristics, being a university graduate (76.9%) and being a public servant (70.5%) were significantly higher in the healthy control group (P = .01 and P = .01, respectively). A family history of PMDD (31.4%), a history of postpartum psychiatric disorders (11.4%), and a history of attempted suicide (7.1%) were higher in the PMDD group compared with the healthy control group (P = .001, P = .003, and P = .024, respectively). Significant differences were also found between PMDD and healthy controls in PMSS score (P ≤ .001), CTQ total scores (P = .002), and subscale scores including emotional abuse and emotional neglect (P = .004), physical abuse (P = .009), and sexual abuse (P = .012). Conclusions: To our knowledge, the present study is the first to investigate associations between PMDD and childhood abuse from Turkey. More comprehensive studies on this topic with larger sample sizes are required to enrich the literature and enable practitioners to be more effective in clinical practice. PMID:25664213

    Here we describe the development of an evidence-based education program for adults about childhood sexual abuse (CSA), called Prevent It! Uniquely, the primary goal of this program was to change the behavior of participants, as well as to increase knowledge about CSA and positive attitudes toward it. A comprehensive review shows no previous similar approach. The program includes a detailed manual to allow standardized administration by trained facilitators, as well as multiple video segments from CSA survivors and professionals. A total of 23 program workshops were run, with 366 adults participating. Of these, 312 (85%) agreed to take part in the study. All completed baseline ratings prior to the program and 195 (63% of study sample) completed follow-up assessments at 3-months. There were no significant differences between the demographic make-up of the baseline group and the follow-up group. Assessments included demographic data, knowledge, attitudes, and several measures of behavior (our primary outcome variable). Behavioral questions asked individuals to select behaviors used in the previous 3-months from a list of options. Questions also included asking "how many times in the previous 3-months" have you "talked about healthy sexual development or Child sexual abuse (CSA) with a child you know"; "suspected a child was sexually abused"; "taken steps to protect a child"; or "reported suspected sexual abuse to police or child welfare"? The majority of attendees were women, with the commonest age group being between 30 and 39 years old. Approximately 33% had experienced CSA themselves. At 3-month follow-up there were highly statistically significant improvements in several aspects of behavior and knowledge, and attitudes regarding CSA. For example, the number of subjects actively looking for evidence of CSA increased from 46% at baseline to 81% at follow-up, while the number of subjects who actively took steps to protect children increased from 25% at baseline to 48

    In child sexual abuse cases, the victim’s testimony is essential, because the victim and the perpetrator tend to be the only eyewitnesses to the crime. A potentially important component of an abuse report is the child’s subjective reactions to the abuse. Attorneys may ask suggestive questions or avoid questioning children about their reactions, assuming that children, given their immaturity and reluctance, are incapable of articulation. We hypothesized that How questions referencing reactions to abuse (e.g., “how did you feel”) would increase the productivity of children’s descriptions of abuse reactions. Two studies compared the extent to which children provided evaluative content, defined as descriptions of emotional, cognitive, and physical reactions, in response to different question-types, including How questions, Wh-questions, Option-posing questions (yes–no or forced-choice), and Suggestive questions. The first study examined children’s testimony (ages 5–18) in 80 felony child sexual abuse cases. How questions were more productive yet the least prevalent, and Option-posing and Suggestive questions were less productive but the most common. The second study examined interview transcripts of 61 children (ages 6 –12) suspected of being abused, in which children were systematically asked How questions regarding their reactions to abuse, thus controlling for the possibility that in the first study, attorneys selectively asked How questions of more articulate children. Again, How questions were most productive in eliciting evaluative content. The results suggest that interviewers and attorneys interested in eliciting evaluative reactions should ask children “how did you feel?” rather than more direct or suggestive questions.

    OBJECTIVE To provide estimates of physical abuse and use of health services among depressed women in order to inform efforts to increase detection and treatment of physical abuse. DESIGN Retrospective assessment of abuse and health services use over 1 year in a cohort of depressed women. SETTING Statewide community sample from Arkansas. PARTICIPANTS We recruited 303 depressed women through random-digit-dial screening. MEASUREMENTS AND MAIN RESULTS Exposure to physical abuse based on the Conflict Tactics Scale, multi-informant estimate of health and mental health services. Over half of the depressed women (55.2%) reported experiencing physical abuse as adults, with 14.5% reporting abuse during the study year. Women abused as adults had significantly more severe depressive symptoms, more psychiatric comorbidity, and more physical illnesses than nonabused women. After controlling for sociodemographic and severity-of-illness factors, recently abused, depressed women were much less likely to receive outpatient care for mental health problems as compared to other depressed women (odds ratio [OR] 0.3;p = .013), though they were more likely to receive health care for physical problems (OR 5.7, p = .021). CONCLUSIONS Because nearly all depressed women experiencing abuse sought general medical rather than mental health care during the year of the study, primary care screening for physical abuse appears to be a critical link to professional help for abused, depressed women. Research is needed to inform primary care guidelines about methods for detecting abuse in depressed women. PMID:9754516

  8. Animal abuse and intimate partner violence: researching the link and its significance in Ireland - a veterinary perspective

    2008-01-01

    Research on domestic violence has established a substantial association between intimate partner abuse and the abuse of children within the home. It is only recently however, that researchers have demonstrated the correlation between non-accidental injury in animals, and abuse of women by their intimate male partners. A growing body of evidence suggests that animal abuse can be an early indicator for other forms of violent behaviour. This research includes the responses of a sample of 23 women using refuge services in the Republic of Ireland. It investigates the connection between domestic violence and animal abuse, and ascertains if there is sufficient support service for animals and people relevant to domestic abuse. In the survey population, 57% of women reported witnessing one or more forms of abuse, or threats of abuse, of their pets. Five of which were reported to have resulted in the death of the pet. Eighty seven per cent of women felt a facility to accommodate pets would have made their decision to leave the family home easier. Four women disclosed that lack of such a service and concern for the welfare of their companion animals caused them to remain in their abusive relationships for longer than they felt appropriate. Nine families placed pets in the care of family or friends, one woman is unaware of the fate of her pet, while the pets of six families remained with the abusive male after his partner entered a refuge. The majority of women felt unable to talk to anyone about their fears for their pets' welfare. Many felt that there is no service which can provide temporary accommodation for womens' pets while they are in refuge. The results obtained support those found elsewhere in larger studies in the USA and UK, and demonstrate an association of animal abuse in households where there is reported domestic violence.

    Coricidin products seemed to be one of the over-the-counter medications being reportedly abused by adolescents, as observed from the Texas Poison Center Network data. This retrospective chart review investigated the occurrence of abuse, developed a patient profile, and defined the clinical effects resulting from the abuse of Coricidin products. Data collected from the Texas Poison Center Network Toxic Exposure Surveillance System database included human exposures between 1998 and 1999, patients > or = 10y old, intentional use or abuse, and single substance ingestion of I of the tablet formulations of Coricidin. Thirty-three cases from 1998 and 59 cases from 1999 were reviewed. Of these cases, 85% met the inclusion criteria. Of the 7 medications searched, only 4 substances were coded for: Coricidin D, Coricidin D (long acting), Coricidin D (cold, flu & sinus) and Coriciding HBP. These contain a combination of dextromethorphan hydrobromide, chlorpheniramine maleate, phenylpropanolamine hydrochloride, and acetaminophen. Of the 78 cases, 63% were male and 38% were female. The mean age was 14.67 years, 77% being between 13 to 17 years old. Eighteen different symptoms were reported: tachycardia 50%, somnolence 24.4%, mydriasis and hypertension 16.7%, agitation 12.8%, disorientation 10.3%, slurred speech 9%, ataxia 6.4%, vomiting 5.1%, dry mouth and hallucinations 3.9%, tremor 2.6%, and headache, dizziness, syncope, seizure, chest pain, and nystagmus each 1.3%; 12.8% of the calls originated from the school nurse. The incidence of abuse reported increased 60% from 1998 to 1999. This worrisome trend suggests increased abuse of these products. PMID:12046973

    The aim of this study was to examine the possible involvement of smooth muscle cell remodeling and the induction of MFG-E8 (milk fat globule protein epidermal growth factor-VIII) in vascular pathophysiology during cocaine administration in cultured cells and rats. Cocaine exerts bifurcate effects on vascular cells; it stimulates vasoconstriction through enhancement of catecholamine release at low doses, while it suppresses cardiovascular functions through inhibition of ion channels at high doses. Short-term exposure to a high concentration of cocaine (3 mM, 24 hr) resulted in cell death of A7r5 rat aorta-derived smooth muscle cells. On the other hand, long-term exposure of the same cells to a low concentration (0.3 mM, ~7 days) resulted in a transient increase in MFG-E8 expression followed by an increased tendency toward cyclin D1, PCNA (proliferating cell nuclear antigen), and CDK4 (cyclin-dependent protein kinase-4) expression. Interestingly, autophagy was not induced, but rather was impaired, in cocaine-treated cells. Increased expressions of MFG-E8, PCNA, and CDK4 were also observed in the aortic vascular cells of rats administered cocaine (50 mg/kg, 2 days, i.v.), confirming that cocaine induced MFG-E8 expression in vivo. Taken together, the results show that MFG-E8 is induced in vascular cells exposed to cocaine, and that this induction is likely to be involved in the vascular toxicity elicited by cocaine abuse.

    Abuse of senior citizens should be paradoxical in a civilized society; however, the U.S. Government Accountability Office reports that 14.1% of noninstitutionalized older adults experienced some type of abuse within the previous year. This is suspected to be an underestimation of the number of abuses reported. In a society where the older population is predicted to increase significantly, it is likely that the number of cases for abused elders will increase proportionately. Through the success of advocacy groups to raise awareness of child and domestic partner abuse, funding has been channeled to shelter these abuse victims. The same cannot be said for elders who are abused. Providing shelter in a safe, secure, medically appropriate environment, free from violence, for an older adult is essential. This article describes a community's collaborative health planning process to respond to elder abuse and develop a program to shelter elders experiencing abuse or suspected abuse. PMID:23636048

    The abuse of synthetic cathinones, widely known as bath salts, has been increasing since the mid-2000s. These substances are derivatives of the naturally occurring compound cathinone, which is the primary psychoactive component of khat. The toxicity of synthetic cathinones includes significant sympathomimetic effects, as well as psychosis, agitation, aggression, and sometimes violent and bizarre behavior. Mephedrone and methylenedioxypyrovalerone are currently the predominantly abused synthetic cathinones. PMID:23869180

    Background Childhood sexual abuse (CSA) is a traumatic life event associated with an increased lifetime risk for psychopathology/morbidity. The long-term biological consequences of CSA-elicited stress on chromosomal stability in adults are unknown. The primary aim of this study was to determine if the rate of acquired chromosomal changes, measured using the cytokinesis-block micronucleus assay on stimulated peripheral blood lymphocytes, differs in adult female monozygotic twins discordant for CSA. Methods Monozygotic twin pairs discordant for CSA were identified from a larger population-based sample of female adult twins for whom the experience of CSA was assessed by self-report (51 individuals including a reference sample). Micronuclei (MN) contain chromatin from structurally normal or abnormal chromosomes that are excluded from the daughter nuclei during cell division and serve as a biomarker to assess acquired chromosomal instability. Results Female twins exposed to CSA exhibited a 1.63-fold average increase in their frequency of MN compared to their nonexposed genetically identical cotwins (Paired t-test, t16 = 2.65, P = 0.017). No additional effects of familial factors were detected after controlling for the effect of CSA exposure. A significant interaction between CSA history and age was observed, suggesting that the biological effects of CSA on MN formation may be cumulative. Conclusions These data support a direct link between CSA exposure and MN formation measured in adults that is not attributable to genetic or environmental factors shared by siblings. Further research is warranted to understand the biological basis for the observed increase in acquired chromosomal findings in people exposed to CSA and to determine if acquired somatic chromosomal abnormalities/somatic clonal mosaicism might mediate the adult pathology associated with CSA.

    The effectiveness of two decision-making training approaches in increasing independent decision-making skills of 36 women with mild mental retardation in response to hypothetical social interpersonal situations involving abuse was evaluated. Participants were randomly assigned to a control or one of two training conditions (a decision-making training approach that either addressed both cognitive and motivational aspects of decision-making or included only instruction on the cognitive aspect of decision-making). Although both approaches were effective relative to a control condition, the combined cognitive and motivational training approach was superior to the cognitive only training approach. The superiority of this approach was also reflected on a verbally presented generalization task requiring participants to respond to a decision-making situation involving abuse from their own perspective and on a locus of control scale that measured perceptions of control.

    Objective Mounting evidence indicates that low levels of n-3 polyunsaturated fatty acids (PUFAs) play a role in the pathophysiology of a large number of psychiatric disorders. In light of the suboptimal n-3 PUFAs intake due to poor dietary habits among substance abusers and the strong associations between aggression, anxiety and substance use disorders we examined if insurance of adequate intakes of n-3 PUFAs with supplementation would decrease their anger and anxiety scores. Method Substance abusers (n=22) were assigned to either 3 g of n-3 PUFAs, mainly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) or soybean oil in identically looking capsules. The trial was double-blind, randomized and lasted 3 months. Anger and anxiety scales were administered at baseline and once a month thereafter. Blood samples were collected at baseline and at the end of the trial. Results Patients' dietary intakes of n-3 PUFAs fell below recommended levels. Assignment to n-3 PUFA treatment was accompanied by significant decreases in anger and anxiety scores compared to placebo assignment. These changes were associated with increases in plasma levels of both EPA and DHA but an increase in EPA was more robustly correlated with low end-of-trial anxiety scores and an increase in DHA was more robustly correlated with low end-of-trial anger scores. Conclusion These pilot data indicate that ensuring adequate n-3 PUFA intake via supplementation benefits substance abusers by reducing their anger and anxiety levels. The strong correlations between an increase in plasma EPA and lower anxiety scores and between an increase in plasma DHA and lower anger scores suggests a need for the further exploration of the differential responses to these two n-3 PUFAs in different psychiatric conditions.

    Twelve adolescent males with a history of chronic solvent abuse were compared with 12 delinquent controls on a battery of neuropsychological tests. Toluene was the active constituent most commonly abused. Solvent abusers tended to have lower overall intelligence test scores. On the Bexley Maudsley Automated Screening Test, the solvent abusers scored significantly lower on tests involving visual processing, especially the Symbol Digit Coding test. These results are cautiously interpreted as indicating that chronic solvent abuse carries an increased risk of cognitive impairment. PMID:2311197

    Continuous measurements of atmospheric methane (CH4) mole fractions measured by NOAA's Global Greenhouse Gas Reference Network in Barrow, AK (BRW), show strong enhancements above background values when winds come from the land sector from July to December from 1986 to 2015, indicating that emissions from arctic tundra continue through autumn and into early winter. Twenty-nine years of measurements show little change in seasonal mean land sector CH4 enhancements, despite an increase in annual mean temperatures of 1.2 ± 0.8°C/decade (2σ). The record does reveal small increases in CH4 enhancements in November and December after 2010 due to increased late-season emissions. The lack of significant long-term trends suggests that more complex biogeochemical processes are counteracting the observed short-term (monthly) temperature sensitivity of 5.0 ± 3.6 ppb CH4/°C. Our results suggest that even the observed short-term temperature sensitivity from the Arctic will have little impact on the global atmospheric CH4 budget in the long term if future trajectories evolve with the same temperature sensitivity.

    Although Contingency Management has been shown to be effective in substance use treatments, community adoption has been slow. In order to increase dissemination of contingency management (CM) into community practice, two community treatment programs collaborated with university faculty investigators to design, implement, and evaluate low-cost, prize-based CM interventions delivered by treatment staff using Petry’s (2000) fishbowl technique. A pre-post study design was used to evaluate the impact of CM on outpatient group attendance. All clients attending the targeted outpatient groups at both treatment programs were eligible to participate. Group attendance was significantly positively impacted after intervention implementation. This is one of the first studies demonstrating successful implementation of CM by community treatment program counselors within their existing treatment groups. The discussion focuses on practical lessons learned during the planning and implementation of the interventions. PMID:20598838

    This retrospective study describes the characteristics and mechanisms of forearm fractures in children <18 months adding to the evidence-base about forearm fractures. It also examines which features of forearm fractures in young children may help discriminate between abusive and noninflicted injuries. Electronic medical records were reviewed for eligible patients evaluated between September 1, 2007 and January 1, 2012 at two children's hospitals in Chicago, IL. The main outcome measures were the type of fracture and the etiology of the fracture (abuse versus not abuse). The 135 included patients sustained 216 forearm fractures. Most were buckle (57%) or transverse (26%). Child protection teams evaluated 47 (35%) of the patients and diagnosed 11 (23%) as having fractures caused by abuse. Children with abusive versus non-inflicted injuries had significant differences in age (median age 7 versus 12 months), race, and presence of additional injuries. Children with abusive forearm fractures often presented without an explanation or a changing history for the injury. Children with non-inflicted forearm fractures often presented after a fall. No particular type of forearm fracture was specific for child abuse. Any forearm fracture in a young child should be evaluated with special attention to the details of the history and the presence of other injuries. Young age, additional injuries, and an absent or inconsistent explanation should increase concern that the fracture was caused by child abuse. PMID:25765815

    Objectives α2C-adrenoceptors (α2C-AR) are involved in behavioural responses relevant to psychiatric disorders and suicide completion. The genetic polymorphism α2CDel322-325-AR confers a loss-of-function phenotype. Functional human studies have associated α2CDel322-325-AR polymorphism with major depression pathophysiology. The aim of this study was to analyse, for the first time, the association of α2CDel322-325-AR polymorphism with suicide completion and with related psychiatric disorders: major depression, schizophrenia, opiate and alcohol abuse and dependence. Methods Post-mortem brain DNA was extracted (n = 516) and genotyping performed by HaeIII restriction endonuclease digestion of PCR products and DNA fragment analysis on capillary sequencer. Amplified products were sequenced to confirm the presence of the polymorphism. Results The frequency of α2CDel322-325-AR in suicide (9%, n = 236) and non-suicide victims (11%, n = 280) was similar. Genotype frequencies for the α2CDel322-325-AR polymorphism in depressed (15%, n = 39) and schizophrenic subjects (18%, n = 39) were higher than in controls (7%, n = 187), but these differences did not reach statistical significance (P = 0.125 and P = 0.063, respectively). A selective and significant association of α2CDel322-325-AR polymorphism with opiate abuse and dependence was found (23%, n = 35, P = 0.011). Conclusions Our results indicate that α2CDel322-325-AR may play a role in the pathophysiology of opiate abuse and dependence and raise the interest for larger genetic associative studies.

    St. John's wort (SJW, Hypericum perforatum) is one of the popular nutraceuticals for treating depression. Methotrexate (MTX) is an immunosuppressant with narrow therapeutic window. This study investigated the effect of SJW on MTX pharmacokinetics in rats. Rats were orally given MTX alone and coadministered with 300 and 150 mg/kg of SJW, and 25 mg/kg of diclofenac, respectively. Blood was withdrawn at specific time points and serum MTX concentrations were assayed by a specific monoclonal fluorescence polarization immunoassay method. The results showed that 300 mg/kg of SJW significantly increased the AUC{sub 0−t} and C{sub max} of MTX by 163% and 60%, respectively, and 150 mg/kg of SJW significantly increased the AUC{sub 0−t} of MTX by 55%. In addition, diclofenac enhanced the C{sub max} of MTX by 110%. The mortality of rats treated with SJW was higher than that of controls. In conclusion, coadministration of SJW significantly increased the systemic exposure and toxicity of MTX. The combined use of MTX with SJW would need to be with caution. -- Highlights: ► St. John's wort significantly increased the AUC{sub 0−t} and C{sub max} of methotrexate. ► Coadministration of St. John's wort increased the exposure and toxicity of methotrexate. ► The combined use of methotrexate with St. John's wort will need to be with caution.

    In the past several years, emphasis on quality metrics in the field of organ transplantation has increased significantly, largely because of the new conditions of participation issued by the Centers for Medicare and Medicaid Services. These regulations directly associate patients' outcomes and measured performance of centers with the distribution of public funding to institutions. Moreover, insurers and marketing ventures have used publicly available outcomes data from transplant centers for business decision making and advertisement purposes. We gave a 10-question survey to attendees of the Transplant Management Forum at the 2009 meeting of the United Network for Organ Sharing to ascertain how centers have responded to the increased oversight of performance. Of 63 responses, 55% indicated a low or near low performance rating at their center in the past 3 years. Respondents from low-performing centers were significantly more likely to indicate increased selection criteria for candidates (81% vs 38%, P = .001) and donors (77% vs 31%, P < .001) as well as alterations in clinical protocols (84% vs 52%, P = .007). Among respondents indicating lost insurance contracts (31%), these differences were also highly significant. Based on respondents' perceptions, outcomes of performance evaluations are associated with significant changes in clinical practice at transplant centers. The transplant community and policy makers should practice vigilance that performance evaluations and regulatory oversight do not inadvertently lead to diminished access to care among viable candidates or decreased transplant volume.

    In this study, tassels of Cave-in-Rock (upland) and Alamo (lowland) were removed at or near tassel emergence to explore its effects on biomass production and quality. Tassel-removed (TR) Cave-in-Rock and Alamo both exhibited a significant (P<0.05) increase in plant heights (not including tassel length), tiller number, and aboveground biomass dry weight (10% and 12%, 30% and 13%, 13% and 18%, respectively by variety) compared to a control (CK) treatment. Notably, total sugar yields of TR Cave-in-Rock and Alamo stems increased significantly (P<0.05 or 0.01) by 19% and 19%, 21% and 14%, 52% and 18%, respectively by variety, compared to those of control switchgrass under 3 treatments by direct enzymatic hydrolysis (DEH), enzymatic hydrolysis after 1% NaOH pretreatment (EHAL) and enzymatic hydrolysis after 1% H2SO4 pretreatment (EHAC). These differences were mainly due to significantly (P<0.05 or 0.01) higher cellulose content, lower cellulose crystallinity indexes (CrI) caused by higher arabinose (Ara) substitution in xylans, and lower S/G ratio in lignin. However, the increases of nitrogen (N) and sulphur (S) concentration negatively affects the combustion quality of switchgrass aboveground biomass. This work provides information for increasing biomass production and quality in switchgrass and also facilitates the inhibition of gene dispersal of switchgrass in China. PMID:25849123

    Based on monthly precipitation data from 74 weather stations in the arid region of northwest China, we employed statistical methods to analyse the characteristics of precipitation and investigated the relationships between precipitation and 11 atmospheric circulations. The results showed that the precipitation in northwest China had a significantly increasing trend (P < 0.01), at a rate of 0.61 mm/year, which is higher than the average rate of China (- 0.16 mm/year) for the same period. Annual precipitation increased markedly after 1987, but the increase in precipitation gradually declined from north to south and from west to east. We found that the precipitation variation in spring, summer, autumn, and winter plays an important role in the yearly change, accounting for 21.6%, 42.4%, 18.4%, and 17.6%, respectively. The correlation analysis indicated that the annual precipitation revealed strong and significant associations with the West Pacific Subtropical High (WPSH, R = 0.60, P < 0.001) and the North America Subtropical High (NASH, R = 0.57, P < 0.001) from 1960 to 2010. We therefore suggest that the strengthening of the WPSH and NASH after the mid-1980s is probably the main cause for the significant increasing trend of precipitation in northwest China.

    An innovative self-contained active cooling system for electronic products, which increases power and packaging densities and improves reliability, was investigated. The cooling technology uses low cost, readily available, and reliable components. While this thermal control method can be applied to many applications, a simple power system cooling application will be demonstrated. The application demonstrates increased power density of a common 48 Vdc to 5Vdc high density DC-DC power converter module having standard dimensions of 2.4in.x4.6in.x0.5in. An increase in power density from 50W/in{sup 3} to over 80W/in{sup 3} was realized. In addition, significantly high calculated MTBF, from 300K hours to greater than 3M hours, was realized with low temperature operation.

    Guidelines to support health care professionals in early detection of, and responses to, suspected Child Abuse and Neglect (CAN) have become increasingly widely available. Yet little is known about professionals' adherence to these guidelines or the determinants that affect their uptake. This study used a cross-sectional design to assess the adherence of Dutch Child Health Care (CHC) professionals to seven key activities described in a national guideline on preventing CAN. This study also examined the presence and strengths of determinants of guideline adherence. Online questionnaires were filled in between May and July 2013 by 164 CHC professionals. Adherence was defined as the extent to which professionals performed each of seven key activities when they suspected CAN. Thirty-three determinants were measured in relation to the guideline, the health professional, the organisational context and the socio-political context. Bivariate and multivariate regression analyses tested associations between determinants and guideline adherence. Most of the responding CHC professionals were aware of the guideline and its content (83.7%). Self-reported rates of full adherence varied between 19.5% and 42.7%. Stronger habit to use the guideline was the only determinant associated with higher adherence rates in the multivariate analysis. Understanding guideline adherence and associated determinants is essential for developing implementation strategies that can stimulate adherence. Although CHC professionals in this sample were aware of the guideline, they did not always adhere to its key recommended activities. To increase adherence, tailored interventions should primarily focus on enhancing habit strength. PMID:26687328

    This study describes the frequency of monoclonal gammopathy of undetermined significance (MGUS) and the changes in some inflammation-related serum proteins in 157 patients with nonimmune chronic idiopathic neutropenia syndrome (NI-CINS). Of these patients, 42 had pronounced neutropenia with neutrophil counts < 1500/microL, and 115 had mild neutropenia with neutrophil counts ranging from 1500 to 2499/microL. Sixty-six volunteers served as healthy control subjects and 157 age- and sex-matched patients hospitalized for nonmalignant diseases served as patient control subjects. We found that 28.6% of patients with pronounced neutropenia and 14.8% of patients with mild neutropenia had increased serum gamma globulins (above the 95% confidence limit of values of the control subjects). In the group of patients with pronounced neutropenia, 30.9% had increased immunoglobulin (Ig)G values and 23.8% had increased IgA values. In the group of patients with mild neutropenia, 17.4% had increased IgG values and 21.7% had increased IgA values. IgG and IgA values strongly correlated with the neutrophil count. No changes in serum IgM were found. Three of 42 patients with pronounced neutropenia (7.14%) and 3 of 115 patients with mild neutropenia (2.61%) had serum immunofixation tests which showed a small monoclonal spike--4 were IgG-kappa type, 1 was IgG-lambda type, and 1 was IgA-kappa type. None of the healthy or patient control subjects had any evidence of MGUS. No significant changes in the amount of monoclonal spikes were documented during an 18- to 143-month follow-up (median, 58 months). Except for significantly increased alpha1-antitrypsin levels, there were no significant differences in the levels of acute-phase proteins studied between the study patients and the control subjects. These findings are consistent with our previous report suggesting the possible existence of an unrecognized low-grade chronic inflammation in patients with NI-CINS, which may be involved in the

    Introduction Sites of chronic inflammation are often associated with the establishment and growth of various malignancies including breast cancer. A common inflammatory condition in humans is autoimmune arthritis (AA) that causes inflammation and deformity of the joints. Other systemic effects associated with arthritis include increased cellular infiltration and inflammation of the lungs. Several studies have reported statistically significant risk ratios between AA and breast cancer. Despite this knowledge, available for a decade, it has never been questioned if the site of chronic inflammation linked to AA creates a milieu that attracts tumor cells to home and grow in the inflamed bones and lungs which are frequent sites of breast cancer metastasis. Methods To determine if chronic inflammation induced by autoimmune arthritis contributes to increased breast cancer-associated metastasis, we generated mammary gland tumors in SKG mice that were genetically prone to develop AA. Two breast cancer cell lines, one highly metastatic (4T1) and the other non-metastatic (TUBO) were used to generate the tumors in the mammary fat pad. Lung and bone metastasis and the associated inflammatory milieu were evaluated in the arthritic versus the non-arthritic mice. Results We report a three-fold increase in lung metastasis and a significant increase in the incidence of bone metastasis in the pro-arthritic and arthritic mice compared to non-arthritic control mice. We also report that the metastatic breast cancer cells augment the severity of arthritis resulting in a vicious cycle that increases both bone destruction and metastasis. Enhanced neutrophilic and granulocytic infiltration in lungs and bone of the pro-arthritic and arthritic mice and subsequent increase in circulating levels of proinflammatory cytokines, such as macrophage colony stimulating factor (M-CSF), interleukin-17 (IL-17), interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), and tumor necrosis factor

    To investigate the relationship between the anxiety and blood pressure (BP) and heart rate (HR) increase in peri-exam period. Sixty-four college students(20.0 ± 0.1 year old) were included in this study. The BP and HR were measured in the morning and in the evening for 3 days during the prereview (ba), review, and exam periods. The BP and HR increase amplitudes (HRIA) of review and exam periods were from the difference of corresponding values and basic values, and the BPIA/baBP and HRIA/baHR were calculated. All of the students completed the Self-Rating Anxiety score (SAS) questionnaire the first day of the exam period. Scores over 50 points were used as the standard for anxiety. From the prereview to exam periods, the BP and HR increased gradually. The exam SBPIA (4.3 ± 1.3 vs. 0.3 ± 0.5 mmHg, P < 0.05) and DBPIA (4.4 ± 1.5 vs. 1.0 ± 0.5 mmHg, P < 0.05) were significantly higher in the anxiety group than in the no-anxiety group. The SBPIA/DBPIA and HRIA showed a similar profile also(9.7 ± 2.1 vs. 1.9 ± 0.9 bpm, P < 0.05). Strong positive correlations were found between the SAS score and BPIA and HRIA both in the review and exam period. The smoking group and family hypertension group had higher anxiety score; meanwhile, their exam BPIAs and HRIAs were significantly higher than their corresponding group. The BP and HR increase in the review and exam period, anxiety is an important factor of BP and HR increase. PMID:21787237

    Polymer semiconductors based on donor-acceptor monomers have recently resulted in significant gains in field effect mobility in organic thin film transistors (OTFTs). These polymers incorporate fused aromatic rings and have been designed to have stiff planar backbones, resulting in strong intermolecular interactions, which subsequently result in stiff and brittle films. The complex synthesis typically required for these materials may also result in increased production costs. Thus, the development of methods to improve mechanical plasticity while lowering material consumption during fabrication will significantly improve opportunities for adoption in flexible and stretchable electronics. To achieve these goals, we consider blending a brittle donor-acceptor polymer, poly[4-(4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b']dithiophen-2-yl)-alt-[1,2,5]thiadiazolo[3,4-c]pyridine] (PCDTPT), with ductile poly(3-hexylthiophene). We found that the ductility of the blend films is significantly improved compared to that of neat PCDTPT films, and when the blend film is employed in an OTFT, the performance is largely maintained. The ability to maintain charge transport character is due to vertical segregation within the blend, while the improved ductility is due to intermixing of the polymers throughout the film thickness. Importantly, the application of large strains to the ductile films is shown to orient both polymers, which further increases charge carrier mobility. These results highlight a processing approach to achieve high performance polymer OTFTs that are electrically and mechanically optimized. PMID:27200458

    To determine whether nitrogen monoxide (nitric oxide; NO) synthase (NOS) and NADPH diaphorase (NDP) co-containing cerebrocortical neurons (NOSN) neurons are affected in patients infected with human immunodeficiency virus type 1 (HIV-1) with and without associated intake of drugs of abuse, we examined the temporal neocortex of 24 individuals: 12 HIV-1 positive (including 3 drug users, 9 non-drug users) and 12 HIV-1 negative (including 6 drug users, and 6 non-drug users). Histochemical labeling for NDP-an enzymatic domain co-expressed in the NOS enzyme-was employed to visualize NOSN. Drug abuse and HIV-1 infection cause independently an increase in NOSN density, but combined they result in up to a 38-fold increase in NOSN density, suggesting that the combination of these factors induces NOS expression powerfully in neurons that normally do not synthesize NDP/NOS. This is associated with an increase in the proportion of NOSN displaying dystrophic changes, indicating that NOSN undergo massive degeneration in association with NOS synthesis induction. The increase in density of NOSN in HIV-1 infected drug abusers may be among the important sources of NO mediating cerebrocortical dysfunction, and the degeneration of NOS-containing local circuit neurons in patients with HIV-1 infection or drug abuse may underlie in part their neuropsychiatric manifestations.

    We reviewed records of adult patients admitted to our burn unit who were reported to abuse drugs or alcohol from 1985 to 1988. The proportion of patients reported as abusing drugs increased significantly from 1987 to 1988, compared to previous years. However, there was no increase in the proportion of patients reported to abuse alcohol. Patients identified as abusing drugs had longer hospital stays, compared to patients who were not reported to abuse substances. Methamphetamine and cocaine were the drugs most often abused by patients who abused drugs or both drugs and alcohol. Mechanisms of burn injury in these patients included "accidental" burn injury related to acute intoxication, and self-injury due to psychosis or depression. PMID:1882020

    Ozone pollution in eastern China has become one of the top environmental issues. Quantifying the temporal trend of surface ozone helps to assess the impacts of the anthropogenic precursor reductions and the likely effects of emission control strategies implemented. In this paper, ozone data collected at the Shangdianzi (SDZ) regional atmospheric background station from 2003 to 2015 are presented and analyzed to obtain the variation in the trend of surface ozone in the most polluted region of China, north of eastern China or the North China Plain. A modified Kolmogorov-Zurbenko (KZ) filter method was performed on the maximum daily average 8 h (MDA8) concentrations of ozone to separate the contributions of different factors from the variation of surface ozone and remove the influence of meteorological fluctuations on surface ozone. Results reveal that the short-term, seasonal and long-term components of ozone account for 36.4, 57.6 and 2.2 % of the total variance, respectively. The long-term trend indicates that the MDA8 has undergone a significant increase in the period of 2003-2015, with an average rate of 1.13 ± 0.01 ppb year-1 (R2 = 0.92). It is found that meteorological factors did not significantly influence the long-term variation of ozone and the increase may be completely attributed to changes in emissions. Furthermore, there is no significant correlation between the long-term O3 and NO2 trends. This study suggests that emission changes in VOCs might have played a more important role in the observed increase of surface ozone at SDZ.

    The White House's proposed budget for the U.S. Geological Survey (USGS) for fiscal year (FY) 2014, which the administration submitted to Congress on 10 April, would provide the agency with 1.17 billion, an increase of 98.02 million, 9.17% more than the FY 2012 enacted budget of $1.07 billion (see Table 1). The proposed budget is a "significant" increase and "makes a statement about the USGS's relevance in the federal research community," USGS acting director Suzette Kimball said at the agency's briefing. Because Congress approved the FY 2013 budget just a few weeks prior to the release of the Obama administration's proposal, the FY 2014 budget is compared with the FY 2012 enacted budget here.

    This study is the first attempt to evaluate the association between the APC I1307K variant and overall cancer risk. It is unique in both its large sample size and in the reliability of data in the control group. The findings described in this article have major implications in terms of identifying asymptomatic individuals who are at increased risk to harbor cancer and therefore targeted to be enrolled in specific early detection and prevention programs. The prevalence of the APC I1307K missense mutation among Ashkenazi Jews is ∼ 6%. Carriers are at an increased risk for colorectal neoplasia. In this study, we examined the association of this variant with non-colorectal cancers. Consecutive 13,013 healthy subjects who underwent screening at the Integrated Cancer Prevention Center between 2006 and 2014 were enrolled. This population was supplemented with 1,611 cancer patients from the same institution. Demographics, medical history, and pathological data were recorded. Mortality data were obtained from the Ministry of Health's registry. The prevalence of APC I1307K in cancer patients and healthy subjects was compared. The APC I1307K variant was detected in 189 (11.8%) cancer patients compared to 614 (4.7%) healthy subjects, reflecting an adjusted age and sex odds ratio (OR) of 2.53 (p < 0.0001). History of two or more cancer types was associated with a positive carrier prevalence (OR = 4.38 p < 0.0001). Males had significantly increased carrier prevalence in lung, urologic, pancreatic, and skin cancers. The carrier prevalence among females was significantly higher only in breast and skin cancers. Female carriers developed cancer at a significantly older age compared to non-carriers (average 62.7 years vs. 57.8, respectively, p = 0.027), had better survival rates (HR = 0.58, p = 0.022) and overall increased longevity (average age of death 78.8 vs. 70.4 years, respectively, p = 0.003). In conclusion, the APC I1307K variant is a reliable marker for overall cancer risk

    The flash visual evoked potential (VEP) is a useful diagnostic modality for visual preservation during surgery. Decreased VEP amplitude is recognized to indicate visual deterioration;however, whether intraoperative VEP can detect visual improvement remains unclear. We describe a craniopharyngioma case with a significant increase in VEP amplitude during surgery. A 67-year-old woman presented with progressive gait disturbance and impaired consciousness. Head magnetic resonance imaging demonstrated a sellar-suprasellar tumor compressing the optic chiasm upward with significant ventricular dilation. Her Glasgow Coma Scale was E3V3M5. Visual fields and acuity could not be examined because of impaired consciousness, and she could not see/recognize objects on a table. Preoperative VEP showed reproducible waveforms. Tumor removal by the extended transsphenoidal approach was performed with VEP monitoring. Increased VEP amplitude was observed after dural incision and persisted until the surgery ended. Postoperative VEP waveforms were also reproducible, but visual fields/acuity could not be examined because of cognitive dysfunction. Useful visual function was restored, and she became independent in daily life. The histological diagnosis was craniopharyngioma. The patient underwent ventriculo-peritoneal shunting for hydrocephalus 16 days after tumor removal. The postoperative course was uneventful and she was transferred to another hospital for rehabilitation. Intraoperative VEP may indicate visual improvement during surgery, which is a useful objective assessment for visual function in patients with impaired consciousness and cognitive dysfunction.

    Subtropical planted forests are rapidly expanding. They are traditionally managed for intensive, short-term goals that often lead to long-term yield decline and reduced carbon sequestration capacity. Here we show how it is possible to increase and sustain carbon stored in subtropical forest plantations if management is switched towards more sustainable forestry. We first conducted a literature review to explore possible management factors that contribute to the potentials in ecosystem C in tropical and subtropical plantations. We found that broadleaves plantations have significantly higher ecosystem C than conifer plantations. In addition, ecosystem C increases with plantation age, and reaches a peak with intermediate stand densities of 1500–2500 trees ha−1. We then used the FORECAST model to simulate the regional implications of switching from traditional to sustainable management regimes, using Chinese fir (Cunninghamia lanceolata) plantations in subtropical China as a study case. We randomly simulated 200 traditional short-rotation pure stands and 200 sustainably-managed mixed Chinese fir – Phoebe bournei plantations, for 120 years. Our results showed that mixed, sustainably-managed plantations have on average 67.5% more ecosystem C than traditional pure conifer plantations. If all pure plantations were gradually transformed into mixed plantations during the next 10 years, carbon stocks could rise in 2050 by 260.22 TgC in east-central China. Assuming similar differences for temperate and boreal plantations, if sustainable forestry practices were applied to all new forest plantation types in China, stored carbon could increase by 1,482.80 TgC in 2050. Such an increase would be equivalent to a yearly sequestration rate of 40.08 TgC yr−1, offsetting 1.9% of China’s annual emissions in 2010. More importantly, this C increase can be sustained in the long term through the maintenance of higher amounts of soil organic carbon and the production of timber

  9. Anti-PD-1 antibody significantly increases therapeutic efficacy of Listeria monocytogenes (Lm)-LLO immunotherapy

    PubMed Central

    2013-01-01

    Background One of the significant tumor immune escape mechanisms and substantial barrier for successful immunotherapy is tumor-mediated inhibition of immune response through cell-to-cell or receptor/ligand interactions. Programmed death receptor-1 (PD-1) interaction with its ligands, PD-L1 and PD-L2, is one of the important strategies that many tumors employ to escape immune surveillance. Upon PD-Ls binding to PD-1, T cell receptor (TCR) signaling is dampened, causing inhibition of proliferation, decreased cytokine production, anergy and/or apoptosis. Thus PD-Ls expression by tumor cells serves as a protective mechanism, leading to suppression of tumor-infiltrating lymphocytes in the tumor microenvironment. Lm-LLO immunotherapies have been shown to be therapeutically effective due to their ability to induce potent antigen-specific immune responses. However, it has been demonstrated that infection with Lm leads to up-regulation of PD-L1 on mouse immune cells that can inhibit effector T cells through PD-1/PD-L1 pathway. Methods Therapeutic and immune efficacy of Listeria-based vaccine (Lm-LLO-E7) in combination with anti-PD-1 antibody was tested in E7 antigen expressing TC-1 mouse tumor model. Tumor growth, survival, as well as peripheral and tumor-infiltrating immune cell profiles after immunotherapy were assessed. Results Here we demonstrate that the combination of an Lm-LLO immunotherapy with anti-PD-1 antibody that blocks PD-1/PD-L1 interaction, significantly improves immune and therapeutic efficacy of treatment in TC-1 mouse tumor model. Importantly, we show that in addition to significant reduction of regulatory T cells (Treg) and myeloid-derived suppressor cells (MDSC) in both spleen and tumor microenvironment that are mediated solely by the Lm-LLO immunotherapy, the addition of anti-PD-1 antibody to the treatment results in significant increase of antigen-specific immune responses in periphery and CD8 T cell infiltration into the tumor. As a result, this

    Background: The direct impact of medical expenses on breast cancer incidence and mortality rate has not been sufficiently addressed. The purpose of this study is to investigate the potential correlation between the incidence and mortality rate of breast cancer and the medical expenses in Taiwan. Materials and Methods: Breast cancer cases were identified from the National Health Insurance Research Database (NHIRD) with corresponding to International Classification of Diseases, and the Ninth Revision (ICD-9) code 174, 1740-1749, 175, 1750 and 1759 from January 1999 to December 2006. Age-specific incidences were estimated by population data obtained from the Department of Statistics, Ministry of the Interior. Medical expenses, including outpatient and inpatient services, were also retrieved from the NHIRD. Results: The incidence increased from 20.06 per 100,000 in 1999 to 30.34 per 100,000 in 2006; the total expenses increased from 1,449,333,521 in 1999 to 4,350,400,592 Taiwan dollars in 2006. The age-standardized mortality rate for female breast cancer remained essentially unchanged, while the age-standardized incidence increased steadily (except 2002-2003). Among the top 20 coexisting ICD-9 codes for expenses, four are directly on cancers, while 16 are on other diseases or symptoms, which are not necessarily caused by breast cancer. Conclusions: Significantly increased medical expenditure on breast cancer failed to bring down its mortality and incidence rate. The finding has implications for healthcare policy planners in proposing strategies for breast cancer control and allocating the resources. PMID:23983817

    The low Curie temperature (T{sub c} = 130 °C) of bulk BaTiO{sub 3} greatly limits its applications. In this work, the phase structures of BaTiO{sub 3} nanoparticles with sizes ranging from 2.5 nm to 10 nm were studied at various temperatures by using aberration-corrected transmission electron microscopy (TEM) equipped with an in-situ heating holder. The results implied that each BaTiO{sub 3} nanoparticle was composed of different phases, and the ferroelectric ones were observed in the shells due to the complicated surface structure. The ferroelectric phases in BaTiO{sub 3} nanoparticles remained at 600 °C, suggesting a significant increase of T{sub c}. Based on the in-situ TEM results and the data reported by others, temperature-size phase diagrams for BaTiO{sub 3} particles and ceramics were proposed, showing that the phase transition became diffused and the T{sub c} obviously increased with decreasing size. The present work sheds light on the design and fabrication of advanced devices for high temperature applications.

    La0.67Sr0.33MnO3 (LSMO) thin films with a significant increased onset temperature of ferromagnetic transition were prepared using an on-axis dc magnetron sputtering from a stoichiometric ceramic target onto one-side polished MgO (0 0 1). The highest temperature of insulator-metal transition was observed at TP = 416 K. Magnetization hysteresis curves taken at T = 398 K indicate the beginning of the ferromagnetic transition above 400 K. The negative magnetoresistance reaches 15% at a temperature of 400 K. We show that the LSMO thin films with increased temperature values of resistance peak TP and Curie temperature TC are characteristic by a proper microstructure with distorted orthorhombic unit cells. This microstructure is developed during the layer growth, it is not caused by the underlying substrate and it is linked with an appropriate pseudocubic out-of-plane lattice parameter ac⊥, splitted Bragg reflections in rocking curves and as well as in reciprocal space maps.

    Cultivation is the most expensive step in the production of biodiesel from microalgae, and substantial research has been devoted to developing more cost-effective cultivation methods. Plant hormones (phytohormones) are chemical messengers that regulate various aspects of growth and development and are typically active at very low concentrations. In this study, we investigated the effect of different phytohormones on microalgal growth and biodiesel production in Chlamydomonas reinhardtii and their potential to lower the overall cost of commercial biofuel production. The results indicated that all five of the tested phytohormones (indole-3-acetic acid, gibberellic acid, kinetin, 1-triacontanol, and abscisic acid) promoted microalgal growth. In particular, hormone treatment increased biomass production by 54 to 69 % relative to the control growth medium (Tris-acetate-phosphate, TAP). Phytohormone treatments also affected microalgal cell morphology but had no effect on the yields of fatty acid methyl esters (FAMEs) as a percent of biomass. We also tested the effect of these phytohormones on microalgal growth in nitrogen-limited media by supplementation in the early stationary phase. Maximum cell densities after addition of phytohormones were higher than in TAP medium, even when the nitrogen source was reduced to 40 % of that in TAP medium. Taken together, our results indicate that phytohormones significantly increased microalgal growth, particularly in nitrogen-limited media, and have potential for use in the development of efficient microalgal cultivation for biofuel production.

    Candida glabrata is reported as the second most prevalent human opportunistic fungal pathogen in the United States. Over the last decades, its incidence increased, whereas that of Candida albicans decreased slightly. One of the main reasons for this shift is attributed to the inherent tolerance of C. glabrata toward the commonly used azole antifungal drugs. Despite a close phylogenetic distance to Saccharomyces cerevisiae, homologous recombination works with poor efficiency in C. glabrata compared to baker's yeast, in fact limiting targeted genetic alterations of the pathogen's genome. It has been shown that nonhomologous DNA end joining is dominant over specific gene targeting in C. glabrata. To improve the homologous recombination efficiency, we have generated a strain in which the LIG4 gene has been deleted, which resulted in a significant increase in correct gene targeting. The very specific function of Lig4 in mediating nonhomologous end joining is the reason for the absence of clear side effects, some of which affect the ku80 mutant, another mutant with reduced nonhomologous end joining. We also generated a LIG4 reintegration cassette. Our results show that the lig4 mutant strain may be a valuable tool for the C. glabrata research community. PMID:26048009

    Hepatitis B virus (HBV) testing and vaccination rates remain low among Asian-American/Pacific Islanders (APIs) despite high rates of HBV infection. The aim of our study was to assess the effectiveness of an outreach campaign to increase HBV knowledge, testing, and vaccination among a cohort of APIs. Vietnamese Americans were invited to participate in a free HBV screening and vaccination outreach program though pubic service announcements. Attendees completed a survey to assess barriers to vaccination and HBV-related knowledge before and after a 30-min education session by a bilingual board-certified gastroenterologist. Among 98 participants, 100% (22/22) of HBV naïve patients were provided a HBV vaccination series at no cost and over 75% (14/18) of HBV-infected patients were connected to further medical care. Notable reported barriers to prior testing and/or vaccination were cost of the vaccine, concern about missing work for evaluation, and lack of provider recommendation. Knowledge levels about HBV risk factors, potential consequences, and treatment options were poor at baseline but significantly increased after the education session (49 vs. 64%, p < 0.001). Outreach campaigns linked with education can successfully address several barriers to HBV testing and offer an approach to improve HBV awareness and prevention among difficult-to-reach populations.

    Background The increased rates of cardiovascular morbidity and mortality in patients with psoriasis are not adequately explained by traditional risk factors. Whether concomitant sleep disorders (SDs) modify the risk of cardiovascular disease (CVD) in patients with psoriasis remains unknown. Methods Using the Taiwan National Health Insurance Research Database (NHIRD), we conducted a cohort study to investigate the association between concomitant SDs and CVD risk in patients with psoriasis. Data from 99,628 adults who received a psoriasis diagnosis during the period from 2004 to 2010 were analyzed. Cox proportional hazards regression analysis models were used to compare the risks of ischemic heart disease (IHD) and stroke between patients with and without SDs. Results Psoriasis patients with a concomitant SD had significantly higher risks of IHD (adjusted hazard ratio [aHR], 1.25; 95% confidence interval [CI], 1.22–1.28) and stroke (aHR, 1.24; 95% CI, 1.16–1.33) as compared with psoriasis patients without SDs. All psoriasis patient subgroups, including those with mild and severe psoriasis and those with and without arthritis, had increased HRs for IHD and stroke. The increases in IHD and stroke risks conferred by SDs were proportional to the dose of hypnotics used. The effect of SDs on the risks of IHD and stroke was greater in young adults than in middle-aged and older adults. Conclusions The risks of IHD and stroke were higher for psoriasis patients with SDs than for those without SDs. Clinicians should carefully evaluate CVD risk, particularly in young patients with psoriasis. PMID:26745869

    A pediatric patient was assaulted while being treated at a Level 1 pediatric trauma center, prompting a Centers for Medicare & Medicaid Services site visit. The process of screening for physical abuse and protection of patients was reevaluated and revised, and a new guideline was implemented and shared with referral hospitals. During this same time period, 13 referral hospitals participated in an unrelated federally funded study determining the impact of recognition and care of injured children in states with and without a pediatric emergency care facility recognition program. A pre-post study analysis revealed that screening for abuse doubled during this time period. PMID:26953535

    Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem.

    AIM: To retrospectively compare previous-day vs split-dose preparation in terms of bowel cleanliness and polyp detection in patients referred for polypectomy. METHODS: Fifty patients underwent two colonoscopies: one diagnostic in a private clinic and a second for polypectomy in a University Hospital. The latter procedures were performed within 12 wk of the index ones. Examinations were accomplished by two experienced endoscopists, different in each facility. Twenty-seven patients underwent screening/surveillance colonoscopy, while the rest were symptomatic. Previous day bowel preparation was utilized initially and split-dose for polypectomy. Colon cleansing was evaluated using the Aronchick scale. We measured the number of detected polyps, and the polyp miss rates per-polyp. RESULTS: Excellent/good preparation was reported in 38 cases with previous-day preparation (76%) vs 46 with split-dose (92%), respectively (P = 0.03). One hundred and twenty-six polyps were detected initially and 169 subsequently (P < 0.0001); 88 vs 126 polyps were diminutive (P < 0.0001), 25 vs 29 small (P = 0.048) and 13 vs 14 equal or larger than 10 mm. The miss rates for total, diminutive, small and large polyps were 25.4%, 30.1%, 13.7% and 6.6%, respectively. Multivariate analysis revealed that split-dose preparation was significantly associated (OR, P) with increased number of polyps detected overall (0.869, P < 0.001), in the right (0.418, P = 0.008) and in the left colon (0.452, P = 0.02). CONCLUSION: Split-dose preparation improved colon cleansing, enhanced polyp detection and unmasked significant polyp miss rates. PMID:26488024

    Individual susceptibility to arsenic-induced carotid atherosclerosis might be associated with genetic variations in arsenic metabolism. The purpose of this study is to explore the interaction effect on risk of carotid atherosclerosis between arsenic exposure and risk genotypes of purine nucleoside phosphorylase (PNP), arsenic (+3) methyltransferase (As3MT), and glutathione S-transferase omega 1 (GSTO1) and omega 2 (GSTO2). A community-based case-control study was conducted in northeastern Taiwan to investigate the arsenic metabolic-related genetic susceptibility to carotid atherosclerosis. In total, 863 subjects, who had been genotyped and for whom the severity of carotid atherosclerosis had been determined, were included in the present study. Individual well water was collected and arsenic concentration determined using hydride generation combined with flame atomic absorption spectrometry. The result showed that a significant dose-response trend (P=0.04) of carotid atherosclerosis risk associated with increasing arsenic concentration. Non-significant association between genetic polymorphisms of PNP Gly51Ser, Pro57Pro, As3MT Met287Thr, GSTO1 Ala140Asp, and GSTO2 A-183G and the risk for development of carotid atherosclerosis were observed. However, the significant interaction effect on carotid atherosclerosis risk was found for arsenic exposure (>50 {mu}g/l) and the haplotypes of PNP (p=0.0115). A marked elevated risk of carotid atherosclerosis was observed in subjects with arsenic exposure of >50 {mu}g/l in drinking water and those who carried the PNP A-T haplotype and at least either of the As3MT risk polymorphism or GSTO risk haplotypes (OR, 6.43; 95% CI, 1.79-23.19). In conclusion, arsenic metabolic genes, PNP, As3MT, and GSTO, may exacerbate the formation of atherosclerosis in individuals with high levels of arsenic concentration in well water (>50 {mu}g/l). - Highlights: {yields}Arsenic metabolic genes might be associated with carotid atherosclerosis. {yields

    Monoclonal gammopathies of undetermined significance (MGUS) have been shown to be associated with an increased risk of fractures. This study describes prospectively the bone status of MGUS patients and determines the factors associated with vertebral fracture. We included prospectively 201 patients with MGUS, incidentally discovered, and with no known history of osteoporosis: mean age 66.6±12.5 years, 48.3% women, 51.7% immunoglobulin G (IgG), 33.3% IgM and 10.4% IgA. Light chain was kappa in 64.2% patients. All patients had spinal radiographs and bone mineral density measurement in addition to gammopathy assessment. At least one prevalent non-traumatic vertebral fracture was discovered in 18.4% patients and equally distributed between men and women. Fractured patients were older, had a lower bone density and had also more frequently a lambda light chain isotype. Compared with patients with κ light chain, the odds ratio of being fractured for patients with λ light chain was 4.32 (95% confidence interval 1.80-11.16; P=0.002). These results suggest a high prevalence of non-traumatic vertebral fractures in MGUS associated with lambda light chain isotype and not only explained by low bone density. PMID:26314987

    Most studies on phosphorus cycle in the natural environment focused on phosphates, with limited data available for the reduced phosphine (PH3). In this paper, matrix-bound phosphine (MBP), gaseous phosphine fluxes and phosphorus fractions in the soils were investigated from a penguin colony, a seal colony and the adjacent animal-lacking tundra and background sites. The MBP levels (mean 200.3 ng kg(-1)) in penguin colony soils were much higher than those in seal colony soils, animal-lacking tundra soils and the background soils. Field PH3 flux observation and laboratory incubation experiments confirmed that penguin colony soils produced much higher PH3 emissions than seal colony soils and animal-lacking tundra soils. Overall high MBP levels and PH3 emissions were modulated by soil biogeochemical processes associated with penguin activities: sufficient supply of the nutrients phosphorus, nitrogen, and organic carbon from penguin guano, high soil bacterial abundance and phosphatase activity. It was proposed that organic or inorganic phosphorus compounds from penguin guano or seal excreta could be reduced to PH3 in the Antarctic soils through the bacterial activity. Our results indicated that penguin activity significantly increased soil phosphine formation and phosphorus contribution, thus played an important role in phosphorus cycle in terrestrial ecosystems of maritime Antarctica.

    Large-scale utilization of solar-energy resources will require considerable advances in energy-storage technologies to meet ever-increasing global energy demands. Other than liquid fuels, existing energy-storage materials do not provide the requisite combination of high energy density, high stability, easy handling, transportability and low cost. New hybrid solar thermal fuels, composed of photoswitchable molecules on rigid, low-mass nanostructures, transcend the physical limitations of molecular solar thermal fuels by introducing local sterically constrained environments in which interactions between chromophores can be tuned. We demonstrate this principle of a hybrid solar thermal fuel using azobenzene-functionalized carbon nanotubes. We show that, on composite bundling, the amount of energy stored per azobenzene more than doubles from 58 to 120 kJ mol-1, and the material also maintains robust cyclability and stability. Our results demonstrate that solar thermal fuels composed of molecule-nanostructure hybrids can exhibit significantly enhanced energy-storage capabilities through the generation of template-enforced steric strain.

    Diabetic foot ulcer (DFU) patients have a greater than twofold increase in mortality compared with nonulcerated diabetic patients. We investigated (a) cause of death in DFU patients, (b) age at death, and (c) relationship between cause of death and ulcer type. This was an eleven-year retrospective study on DFU patients who attended King's College Hospital Foot Clinic and subsequently died. A control group of nonulcerated diabetic patients was matched for age and type of diabetes mellitus. The cause of death was identified from death certificates (DC) and postmortem (PM) examinations. There were 243 DFU patient deaths during this period. Ischaemic heart disease (IHD) was the major cause of death in 62.5% on PM compared to 45.7% on DC. Mean age at death from IHD on PM was 5 years lower in DFU patients compared to controls (68.2 ± 8.7 years versus 73.1 ± 8.0 years, P = 0.015). IHD as a cause of death at PM was significantly linked to neuropathic foot ulcers (OR 3.064, 95% CI 1.003–9.366, and P = 0.049). Conclusions. IHD is the major cause of premature mortality in DFU patients with the neuropathic foot ulcer patients being at a greater risk. PMID:27213157

    An increasing number of studies in the past decade have shown that sexual abuse of children is disturbingly common. The author reviews some of the more recent knowledge about the problem, with particular reference to medical implications. The incidence and distribution of the problem and the relative importance of the medical examination are reviewed, and the diagnostic significance of clinical presentations such as vulvovaginitis, recurrent urinary tract infection and masturbation is evaluated. The agents responsible for sexually transmitted diseases in abused children are reviewed. Many crucial psychosocial issues are raised in the evaluation and management of sexual abuse. The author discusses some aspects of abuse that are hard to confront, such as the possible pleasure of the child and the nonoffending role of the mother in cases of incest. Information from sources other than the medical literature on the characteristics of abusers, therapy and prevention is reviewed. The medical implications of the Badgley Report are also discussed.

    The challenge of eliminating Pseudomonas aeruginosa infections, such as in cystic fibrosis lungs, remains unchanged due to the rapid development of antibiotic resistance. Poor drug penetration into dense P. aeruginosa biofilms plays a vital role in ineffective clearance of the infection. Thus, the current antibiotic therapy against P. aeruginosa biofilms need to be revisited and alternative antibiofilm strategies need to be invented. Fungal quorum sensing molecule (QSM), farnesol, appears to have detrimental effects on P. aeruginosa. Thus, this study aimed to codeliver naturally occurring QSM farnesol, with the antibiotic ciprofloxacin as a liposomal formulation to eradicate P. aeruginosa biofilms. Four different liposomes (with ciprofloxacin and farnesol, Lcip+far; with ciprofloxacin, Lcip; with farnesol, Lfar; control, Lcon) were prepared using dehydration-rehydration method and characterized. Drug entrapment and release were evaluated by spectrometry and high performance liquid chromatography (HPLC). The efficacy of liposomes was assessed using standard biofilm assay. Liposome-treated 24 h P. aeruginosa biofilms were quantitatively assessed by XTT reduction assay and crystal violet assay, and qualitatively by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). Ciprofloxacin release from liposomes was higher when encapsulated with farnesol (Lcip+far) compared to Lcip (3.06% vs 1.48%), whereas farnesol release was lower when encapsulated with ciprofloxacin (Lcip+far) compared to Lfar (1.81% vs 4.75%). The biofilm metabolism was significantly lower when treated with Lcip+far or Lcip compared to free ciprofloxacin (XTT, P < 0.05). When administered as Lcip+far, the ciprofloxacin concentration required to achieve similar biofilm inhibition was 125-fold or 10-fold lower compared to free ciprofloxacin or Lcip, respectively (P < 0.05). CLSM and TEM confirmed predominant biofilm disruption, greater dead cell ratio, and increased depth of

    Photosynthetic capacity is one of the most sensitive parameters of terrestrial biosphere models whose representation in global scale simulations has been severely hampered by a lack of systematic analyses using a sufficiently broad database. Due to its coupling to stomatal conductance changes in the parameterisation of photosynthetic capacity may potentially influence transpiration rates and vegetation surface temperature. Here, we provide a constrained parameterisation of photosynthetic capacity for different plant functional types in the context of the photosynthesis model proposed by Farquhar et al. (1980), based on a comprehensive compilation of leaf photosynthesis rates and leaf nitrogen content. Mean values of photosynthetic capacity were implemented into the coupled climate-vegetation model ECHAM5/JSBACH and modelled gross primary production (GPP) is compared to a compilation of independent observations on stand scale. Compared to the current standard parameterisation the root-mean-squared difference between modelled and observed GPP is substantially reduced for almost all PFTs by the new parameterisation of photosynthetic capacity. We find a systematic depression of NUE (photosynthetic capacity divided by leaf nitrogen content) on certain tropical soils that are known to be deficient in phosphorus. Photosynthetic capacity of tropical trees derived by this study is substantially lower than standard estimates currently used in terrestrial biosphere models. This causes a decrease of modelled GPP while it significantly increases modelled tropical vegetation surface temperatures, up to 0.8°C. These results emphasise the importance of a constrained parameterisation of photosynthetic capacity not only for the carbon cycle, but also for the climate system.

    Prescription drug abuse has reached an epidemic level in the United States. The prevalence of prescription drug abuse escalated rapidly beginning in the late 1990s, requiring a significant increase in research to better understand the nature and treatment of this problem. Since this time, a research literature has begun to develop and has provided important information about how prescription drug abuse is similar to, and different from the abuse of other substances. This introduction to a special issue of the Journal of Substance Abuse Treatment on prescription drug abuse provides an overview of the current status of the research literature in this area. The papers in this special issue include a sampling of the latest research on the epidemiology, clinical correlates, treatment, and public policy considerations of prescription drug abuse. Although much has been learned about prescription drug abuse in recent years, this research remains in early stages, particularly with respect to understanding effective treatments for this population. Future research priorities include studies on the interaction of prescription drugs with other licit and illicit substances, the impact of prescription drug abuse across the lifespan, the optimal treatment for prescription drug abuse and co-occurring conditions, and effective public policy initiatives for reducing prescription drug abuse.

    The present study examined the relationship among physical abuse, psychological abuse, perceived family functioning and adolescent suicidal ideation in Shanghai, China. Perceived family functioning was investigated as a possible moderator between physical abuse, psychological abuse and suicidal ideation. A cross sectional survey using convenience sampling was conducted. A total of 560 valid self-administered questionnaires were completed by the students aged from 12 to 17 in Shanghai. Descriptive statistical analyses, Pearson correlations analyses, and hierarchical regression analyses were adopted as methods of data analyses. Results indicated that physical abuse was significantly associated with greater adolescent suicidal ideation, while a higher level of perceived family functioning was significantly associated with lower suicidal ideation. However, psychological abuse was not associated with suicidal ideation. Perceived family functioning was shown to be a moderator between physical abuse and suicidal ideation. Specifically, mutuality and family communication moderated the relationship between physical abuse and suicidal ideation. To decrease adolescent suicidal ideation, measures are suggested to prevent physical abuse and enhance family functioning. First, it is important to increase the parents' awareness of the meaning and boundaries of physical abuse, as well as the role it plays in contributing to adolescent suicidal ideation. Second, parents should be taught appropriate parenting skills and knowledge and be guided to treat the children as individuals with their unique personality, rights and privileges. Third, it is important to promote family harmony, effective communication as well as mutual trust, concern and understanding among family members. PMID:23899534

    Intimate partner violence (IPV) often includes economic abuse as one tactic commonly used by an abuser; unfortunately, there is a lack of empirical understanding of economic abuse. Additionally, research is limited on the predictors of economic self-sufficiency in the lives of women experiencing IPV. This paper furthers our knowledge about economic abuse and its relationship with economic self-sufficiency by presenting the results from an exploratory study with IPV survivors participating in a financial literacy program. Of the 120 individuals who participated in the first wave, 94% experienced some form of economic abuse, which also correlated highly with other forms of IPV. Seventy-nine percent experienced some form of economic control, 79% experienced economic exploitative behaviors, and 78% experienced employment sabotage. MANOVA results also indicated that economic control differed significantly based on education with those with a high school education experiencing higher rates than those with less than high school education or those with some college. Finally, results from the OLS regressions indicated that experiencing any form of economic abuse as well as economic control significantly predicted a decrease in economic self sufficiency. Implications suggest that advocates should assess for economic abuse when working with survivors and should be prepared to offer financial tools to increase survivors' economic self-sufficiency. Policymakers should understand the ramifications of economic abuse and create policies that support survivors and prohibit economic abuse. Finally, more research is needed to fully understand economic abuse and its impact on survivors and their economic self-sufficiency. PMID:21987509

    Context: Elder abuse and social neglect are unrecognized problem. Many forms of elder abuse exist including physical, psychological, financial, sexual and social neglect. Social neglect is experienced by elderly through loss of friends and family members. Aim: Comparison of perceived abuse and social neglect among elderly residing in selected rural and urban areas. Settings and Design: Study setting was a rural area Pohir and urban area Jamalpur of district Ludhiana. Subjects and Methods: A sample of 200 subjects (100 subjects each from rural and urban area respectively) of age 60 years and above was drawn by cluster sampling technique and interview method was used to collect data by using Likert scale. Statistical Analysis: Descriptive and inferential statistics were carried out with SPSS package. Results: Results of the present study revealed that perceived physical abuse (25%) was higher among elderly residing in rural and it was found significantly higher among female elderly who were illiterate, widow/widower and partially dependent on caregiver whereas perceived psychological abuse (71%), financial abuse (37%) and social neglect (74%) were higher among elderly residing in urban. A significant association was found between psychological abuse and educational status, which inferred that as the level of education increases perception of psychological abuse also increases. The perceived financial abuse was significantly higher among male elderly who were financially independent. Conclusion: It was concluded that social neglect was most common, followed by psychological abuse and financial abuse among elderly residing in urban whereas physical abuse was more prevalent among elderly residing in rural.

    The sexual abuse of a child or young person constitutes a major social and public health problem and there is recent evidence that intra-familial (IF) sexual abuses are more serious in their consequences than extra-familial (EF). However, there are no studies on this phenomenon in Portugal. Thus, the aim of the present study is to contribute to a better characterization of these types of abuses and to identify possible differences between IF and EF cases. A retrospective study was preformed based on medico-legal reports related to victims below the age of 18, suspected of being sexually abused (n = 764), corresponding to 67% of the total of observed sexual crimes. Results revealed that 34.9% of the abuses are IF and they show statistically significant differences when compared to EF cases. These are due to the following factors found in IF situations: a) lower victim age; b) closeness between victim and abuser; c) abusers with a higher rate of previous sexual abuse; d) sexual practices of reduced physical intrusion; e) decreased physical violence but increased emotional violence; f) greater delay between last abuse and the forensic exam; g) reduced number of injuries or biological evidence (none in the great majority of the cases). Results point out the existence of several characteristics in IF abuse that have been identified as factors that influence the severity of the abuse consequences. Among them are: a) lower victim age; b) greater proximity to the abuser; c) increased amount of emotional violence. These factors account for the reduced visibility of this kind of cases and therefore explain their delayed disclosure and diagnosis. The association of this fact with the reduced intrusiveness of this sort of practice and the consequent decrease in number of injuries and other evidence leads to a marked reduction of the number of cases where evidence of the abuse can be found by physical examination alone. The above aspects underlie the need of using different

    Understanding population status for endangered species is critical to developing and evaluating recovery plans mandated by the Endangered Species Act. For sea turtles, changes in abundance are difficult to detect because most life stages occur in the water. Currently, nest counts are the most reliable way of assessing trends. We determined the rate of growth for leatherback turtle (Dermochelys coriacea) nest numbers in Florida (USA) using a multilevel Poisson regression. We modeled nest counts from 68 beaches over 30 years and, using beach-level covariates (including latitude), we allowed for partial pooling of information between neighboring beaches. This modeling approach is ideal for nest count data because it recognizes the hierarchical structure of the data while incorporating variables related to survey effort. Nesting has increased at all 68 beaches in Florida, with trends ranging from 3.1% to 16.3% per year. Overall, across the state, the number of nests has been increasing by 10.2% per year since 1979. Despite being a small population (probably < 1000 individuals), this nesting population may help achieve objectives in the federal recovery plan. This exponential growth rate mirrors trends observed for other Atlantic populations and may be driven partially by improved protection of nesting beaches. However, nesting is increasing even where beach protection has not been enhanced. Climate variability and associated marine food web dynamics, which could enhance productivity and reduce predators, may be driving this trend. PMID:21516903

  6. Strong Selection Significantly Increases Epistatic Interactions in the Long-Term Evolution of a Protein

    Epistatic interactions between residues determine a protein’s adaptability and shape its evolutionary trajectory. When a protein experiences a changed environment, it is under strong selection to find a peak in the new fitness landscape. It has been shown that strong selection increases epistatic interactions as well as the ruggedness of the fitness landscape, but little is known about how the epistatic interactions change under selection in the long-term evolution of a protein. Here we analyze the evolution of epistasis in the protease of the human immunodeficiency virus type 1 (HIV-1) using protease sequences collected for almost a decade from both treated and untreated patients, to understand how epistasis changes and how those changes impact the long-term evolvability of a protein. We use an information-theoretic proxy for epistasis that quantifies the co-variation between sites, and show that positive information is a necessary (but not sufficient) condition that detects epistasis in most cases. We analyze the “fossils” of the evolutionary trajectories of the protein contained in the sequence data, and show that epistasis continues to enrich under strong selection, but not for proteins whose environment is unchanged. The increase in epistasis compensates for the information loss due to sequence variability brought about by treatment, and facilitates adaptation in the increasingly rugged fitness landscape of treatment. While epistasis is thought to enhance evolvability via valley-crossing early-on in adaptation, it can hinder adaptation later when the landscape has turned rugged. However, we find no evidence that the HIV-1 protease has reached its potential for evolution after 9 years of adapting to a drug environment that itself is constantly changing. We suggest that the mechanism of encoding new information into pairwise interactions is central to protein evolution not just in HIV-1 protease, but for any protein adapting to a changing environment.

    Epistatic interactions between residues determine a protein's adaptability and shape its evolutionary trajectory. When a protein experiences a changed environment, it is under strong selection to find a peak in the new fitness landscape. It has been shown that strong selection increases epistatic interactions as well as the ruggedness of the fitness landscape, but little is known about how the epistatic interactions change under selection in the long-term evolution of a protein. Here we analyze the evolution of epistasis in the protease of the human immunodeficiency virus type 1 (HIV-1) using protease sequences collected for almost a decade from both treated and untreated patients, to understand how epistasis changes and how those changes impact the long-term evolvability of a protein.

    Increasing Australian bush-fire frequencies over the last decade has indicated a major climatic change in coming future. Understanding such climatic change for Australian bush-fire is limited and there is an urgent need of scientific research, which is capable enough to contribute to Australian society. Frequency of bush-fire carries information on spatial, temporal and climatic aspects of bush-fire events and provides contextual information to model various climate data for accurately predicting future bush-fire hot spots. In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. Our analysis also indicates that Australian weekly bush-fire frequencies increased by 40% over the last 5 years, particularly during summer months, implicating a serious climatic shift.

    Objective & Design. We undertook a retrospective review of children diagnosed with acute lymphoblastic leukemia (ALL) and treated with modern COG protocols (n = 80) to determine longitudinal changes in body mass index (BMI) and the prevalence of obesity compared with a healthy reference population. Results. At diagnosis, the majority of patients (77.5%) were in the healthy weight category. During treatment, increases in BMI z-scores were greater for females than males; the prevalence of obesity increased from 10.3% to 44.8% (P < 0.004) for females but remained relatively unchanged for males (9.8% to 13.7%, P = 0.7). Longitudinal analysis using linear mixed-effects identified associations between BMI z-scores and time-dependent interactions with sex (P = 0.0005), disease risk (P < 0.0001), age (P = 0.0001), and BMI z-score (P < 0.0001) at diagnosis and total dose of steroid during maintenance (P = 0.01). Predicted mean BMI z-scores at the end of therapy were greater for females with standard risk ALL irrespective of age at diagnosis and for males younger than 4 years of age at diagnosis with standard risk ALL. Conclusion. Females treated on standard risk protocols and younger males may be at greatest risk of becoming obese during treatment for ALL. These subgroups may benefit from intervention strategies to manage BMI during treatment for ALL. PMID:26101530

    Objectives Traditional hazards such as poor sanitation currently account for most of Africa’s environmentally related disease burden. However, with rapid development absent appropriate safeguards for environment and health, modern environmental health hazards (MEHHs) may emerge as critical contributors to the continent’s disease burden. We review recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products. Our purpose is to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development. Data sources We reviewed published epidemiologic, exposure, and environmental studies of chemical agents such as heavy metals and pesticides. Data synthesis The body of evidence demonstrates ongoing environmental releases of MEHHs and human exposures sometimes at toxicologically relevant levels. Several sources of MEHHs in environmental media have been identified, including natural resource mining and processing and automobile exhaust. Biomonitoring studies provided direct evidence of human exposure to metals such as mercury and lead and pesticides such as p,p′-dichlorodiphenyltrichloroethane (DDT) and organophosphates. Land and water resource pollution and industrial air toxics are areas of significant data gaps, notwithstanding the presence of several emitting sources. Conclusion Unmitigated MEHH releases and human exposure have implications for Africa’s disease burden. For Africans encumbered by conditions such as malnutrition that impair resilience to toxicologic challenges, the burden may be higher. A shift in public health policy toward accommodating the emerging diversity in Africa’s environmental health issues is necessary to successfully alleviate the burden of avoidable ill health and premature death for all its communities now and in the future.

    The epidemic West Nile Virus (WNV) infections observed in the last years, particularly those in the USA in 1999 and the following years, have led to an increasing interest in this zoonotic infection. Here, the most prominent aspects of WNV biology and epidemiology are presented. Clinical signs observed in men and horses are described, as well as the current state of diagnostics and immunoprophylaxis. Preliminary results of investigations on the prevalence of WNV in Germany show that migrating birds have been in contact with WNV; there is however no indication for the presence of this virus. While WNV is endemic in many parts of the "Old World", thus inducing "natural immunity" in (migrating) birds and vertebrates, a susceptible bird population with no existing immunity against this virus was exposed in the "New World".

    Evidence for the health-promoting effects of food rich in n-3 polyunsaturated fatty acids (n-3 PUFA) is reviewed. Pork is an important meat source for humans. According to a report by the US Department of Agriculture ( http://www.ers.usda.gov/topics ), the pork consumption worldwide in 2011 was about 79.3 million tons, much higher than that of beef (48.2 million tons). Pork also contains high levels of unsaturated fatty acids relative to ruminant meats (Enser, M., Hallett, K., Hewett, B., Fursey, G. A. J. and Wood, J. D. (1996) . Fatty acid content and composition of English beef, lamb, and pork at retail. Meat Sci. 44:443-458). The available literature indicates that the levels of eicosatetraenoic and docosahexaenoic in pork may be increased by fish-derived or linseed products, the extent of which being dependent on the nature of the supplementation. Transgenic pigs and plants show promise with high content of n-3 PUFA and low ratio of n-6/n-3 fatty acids in their tissues. The approaches mentioned for decreasing n-6/n-3 ratios have both advantages and disadvantages. Selected articles are critically reviewed and summarized. PMID:26237277

    Donor T-cell immune responses can eradicate lymphomas after allogeneic hematopoietic stem cell transplantation (AHSCT), but can also damage healthy tissues resulting in harmful graft-versus-host disease (GVHD). Next-generation sequencing has recently identified many new genetic lesions in follicular lymphoma (FL). One such gene, tumor necrosis factor receptor superfamily 14 (TNFRSF14), abnormal in 40% of FL patients, encodes the herpes virus entry mediator (HVEM) which limits T-cell activation via ligation of the B- and T-lymphocyte attenuator. As lymphoma B cells can act as antigen-presenting cells, we hypothesized that TNFRSF14 aberrations that reduce HVEM expression could alter the capacity of FL B cells to stimulate allogeneic T-cell responses and impact the outcome of AHSCT. In an in vitro model of alloreactivity, human lymphoma B cells with TNFRSF14 aberrations had reduced HVEM expression and greater alloantigen-presenting capacity than wild-type lymphoma B cells. The increased immune-stimulatory capacity of lymphoma B cells with TNFRSF14 aberrations had clinical relevance, associating with higher incidence of acute GVHD in patients undergoing AHSCT. FL patients with TNFRSF14 aberrations may benefit from more aggressive immunosuppression to reduce harmful GVHD after transplantation. Importantly, this study is the first to demonstrate the impact of an acquired genetic lesion on the capacity of tumor cells to stimulate allogeneic T-cell immune responses which may have wider consequences for adoptive immunotherapy strategies.

    2009-06-01

    This study examines the bushfire (wildland fire) risk to the built environment in Australia. The most salient result is that the annual probability of building destruction has remained almost constant over the last century despite large demographic and social changes as well as improvements in fire fighting technique and resources. Most historical losses have taken place in a few extreme fires which if repeated are likely to overwhelm even the most professional of fire services. We also calculate the average annual probability of a random home on the urban-bushland interface being destroyed by a bushfire to be of the order of 1 in 6500, a factor 6.5 times lower than the ignition probability of a structural house fire. Thus on average and if this risk was perceived rationally, the incentive for individual homeowners to mitigate and reduce the bushfire danger even further is low. This being the case and despite predictions of an increasing likelihood of conditions favouring bushfires under global climate change, we suspect that building losses due to bushfires are unlikely to alter materially in the near future.

    studies on greenhouse gas emissions from animals concentrated on domestic animals, with limited data available from wild animals. The number of marine animals is potentially large in coastal Antarctica. In this paper, N2O and CH4 emissions were investigated from a penguin colony, a seal colony, a skua colony, the adjacent animal-lacking tundra, and background tundra sites to test the effects of marine animals on their fluxes in maritime Antarctica. Extremely high N2O emissions occurred in the penguin puddles (mean 392 µg N2O m-2 h-1) and seal wallows (mean 579 µg N2O m-2 h-1). The N2O emissions from animal colony tundra (13-57 µg N2O m-2 h-1) are much higher than those from the animal-lacking tundra, whereas the background tundra showed negligible N2O fluxes. Penguin puddles and seal wallows were stronger CH4 emitters than animal colony tundra soils, while animal-lacking tundra soils were strong CH4 sinks. Overall high N2O and CH4 emissions were modulated by soil physical and chemical processes associated with marine animal activities: sufficient supply of the nutrients NH4+-N and NO3--N, total nitrogen, and total organic carbon from marine animal excreta, animal tramp, and high soil water-filled pore space. Laboratory incubation experiments further confirmed that penguin and seal colony soils produced much higher N2O and CH4 emissions than animal-lacking tundra soils. Our results indicate that marine animal colonies are the hot spots for N2O and CH4 emissions in maritime Antarctica, and even at the global scale, and current climate warming will further increase their emissions.

    The aim of the study was to investigate the association between social and behavioural factors, and the use of different types of drugs in a cohort of 8168 Swedish men conscripted for military service in 1969-70. Data about social and behavioural characteristics, self-reported use of alcohol and narcotics was obtained from a survey of all Swedish conscripts. Information on intravenous drug abuse up to 1970 was obtained from a survey of injecting males among persons brought to the central police arrest. A higher proportion of intravenous drug abusers than cannabis abusers came from social class III, had divorced parents, had been in contact with the police and juvenile authorities, and had low emotional control. Indicators of deviant behaviour, e.g. truancy, having run away from home, and contact with police or juvenile authorities, were associated with high odds ratios for intravenous drug abuse and for cannabis abuse. In multivariate analyses, these risk factors still carried significantly increased odds ratios. In general, the odds ratios associated with these background factors were higher for intravenous drug abuse than for cannabis abuse. The risk increased, however, with increasing level of cannabis abuse. In conclusion, poor social background and deviant behaviour was strongly associated with future intravenous drug addiction, whereas the association was much weaker in the case of future cannabis abuse.

    A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths. PMID:25981223

    Background Approximately 1.9 million persons in the U.S. have prescription opioid use disorders often with concomitant bodily pain, but systematic data on the impact of pain on abuse liability of opioids is lacking. The purpose of this study was to determine whether pain alters the intranasal abuse liability of oxycodone, a commonly prescribed and abused analgesic, in males and females. Methods Sporadic prescription opioid abusers (10 females, 10 males) participated in this mixed (between and within-subject), randomized inpatient study. Experimental sessions (n=6) tested intranasal placebo, oxycodone 15 or 30 mg/70 kg during cold pressor testing (CPT) and a warm water control. Observer- and subject-rated drug effect measures, analgesia, physiologic and cognitive effects were assessed. Results The CPT significantly increased blood pressure, heart rate, pain, stress, and “opiate desire” compared to the no-pain control but did not alter opioid liking, high or street value. Intranasal oxycodone produced effects within 10 minutes, significantly decreasing pain and significantly increasing subjective measures of abuse liability (e.g., high). Females had higher ratings of street value, high, and liking for one or both active doses. Conclusions The CPT was a reliably painful and stressful stimulus that did not diminish the abuse liability of intranasal Oxycodone®. Females were more sensitive to oxycodone on several abuse liability measures that warrant further follow-up. Snorting oxycodone rapidly produced psychoactive effects indicative of substantial abuse liability. PMID:22209386

    Objectives To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. Design A 6-year retrospective review. Setting California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. Participants All dextromethorphan abuse cases reported to the CPCS, AAPCC, and DAWN. The main exposures of dextromethorphan abuse cases included date of exposure, age, acute vs long-term use, coingestants, product formulation, and clinical outcome. Main Outcome Measure The annual proportion of dextromethorphan abuse cases among all exposures reported to the CPCS, AAPCC, and DAWN databases. Results A total of 1382 CPCS cases were included in the study. A 10-fold increase in CPCS dextromethorphan abuse cases from 1999 (0.23 cases per 1000 calls) to 2004 (2.15 cases per 1000 calls) (odds ratio, 1.48; 95% confidence interval, 1.43–1.54) was identified. Of all CPCS dextromethorphan abuse cases, 74.5% were aged 9 to 17 years; the frequency of cases among this age group increased more than 15-fold during the study (from 0.11 to 1.68 cases per 1000 calls). Similar trends were seen in the AAPCC and DAWN databases. The highest frequency of dextromethorphan abuse occurred among adolescents aged 15 and 16 years. The most commonly abused product was Coricidin HBP Cough & Cold Tablets. Conclusions Our study revealed an increasing trend of dextromethorphan abuse cases reported to the CPCS that is paralleled nationally as reported to the AAPCC and DAWN. This increase was most evident in the adolescent population. PMID:17146018

    2015-01-01

    Background Experiencing abuse during childhood affects the psychological well-being of individuals throughout their lives and may even influence their offspring by enhancing the likelihood of an intergenerational transmission of violence. Understanding the effects of childhood maltreatment on child-rearing practices and intimate partner violence might be of particular importance to overcome the consequences of violent conflicts in African societies. Objective Using Burundi as an example, we aimed to explore the associations between childhood maltreatment, intimate partner violence, perceived partner intimidation, gender and the probability of violently acting out against one's own children or romantic partner. Methods Amongst a sample of 141 men and 141 women in the capital of Burundi, we identified those who had biological children and those who lived or had lived in relationships. Using culturally appropriate instruments, we enquired about their exposure to childhood maltreatment and partner violence as well as their inclinations to act out violently. Results We found that childhood maltreatment and perceived partner intimidation were strong predictors for the perpetration of violence against children. Moreover, we found that women were more likely to use violence against children if they experienced partner violence and less likely to resort to violence if they felt intimidated. Men were more likely to perpetrate violence against their partner. Childhood maltreatment was again a strong predictor. The more women experienced partner violence, the more they fought back. Conclusions Childhood maltreatment is a strong predictor for domestic violence and has to be addressed to interrupt the cycle of violence in post-conflict countries. PMID:26679146

  10. Intracranial Self-Stimulation to Evaluate Abuse Potential of Drugs

    PubMed Central

    Miller, Laurence L.

    2014-01-01

    Intracranial self-stimulation (ICSS) is a behavioral procedure in which operant responding is maintained by pulses of electrical brain stimulation. In research to study abuse-related drug effects, ICSS relies on electrode placements that target the medial forebrain bundle at the level of the lateral hypothalamus, and experimental sessions manipulate frequency or amplitude of stimulation to engender a wide range of baseline response rates or response probabilities. Under these conditions, drug-induced increases in low rates/probabilities of responding maintained by low frequencies/amplitudes of stimulation are interpreted as an abuse-related effect. Conversely, drug-induced decreases in high rates/probabilities of responding maintained by high frequencies/amplitudes of stimulation can be interpreted as an abuse-limiting effect. Overall abuse potential can be inferred from the relative expression of abuse-related and abuse-limiting effects. The sensitivity and selectivity of ICSS to detect abuse potential of many classes of abused drugs is similar to the sensitivity and selectivity of drug self-administration procedures. Moreover, similar to progressive-ratio drug self-administration procedures, ICSS data can be used to rank the relative abuse potential of different drugs. Strengths of ICSS in comparison with drug self-administration include 1) potential for simultaneous evaluation of both abuse-related and abuse-limiting effects, 2) flexibility for use with various routes of drug administration or drug vehicles, 3) utility for studies in drug-naive subjects as well as in subjects with controlled levels of prior drug exposure, and 4) utility for studies of drug time course. Taken together, these considerations suggest that ICSS can make significant contributions to the practice of abuse potential testing. PMID:24973197

    Abstract Background: To determine the differential risk of behaviors associated with lethal violence and functioning outcomes for abused women with children who received an intervention of shelter or justice services and return to the abuser were compared with women who did not return. Methods: The study was carried out using a matched-pair analysis of 152 women. Measures of risk of behaviors associated with lethal violence, type, and severity of abuse, and poor mental health symptoms were measured every 4 months for 24 months. Results: Irrespective of service used, women returning to the abuser reported significantly (p<0.001) more risk of behaviors associated with lethal violence compared to women who did not return. Additionally, severity of physical abuse was significantly higher (p<0.01) for women returning to the abuser who had been in a shelter but not for women who received a protection order. Similarly, levels of depression, posttraumatic stress disorder, and anxiety were significantly higher (p<0.01) for sheltered women who returned to the abuser but not for women using a protection order who returned. Conclusions: Risk of behaviors associated with lethal violence increases when abused women return to live with the abuser. Abused women should be informed of the heightened risk and greater probability for poor mental health. PMID:25714332

    In this study, we compared the efficacy of a group relapse prevention program using the cognitive behavioral therapy-based workbook, Serigaya Methamphetamine Relapse Prevention Program (SMARPP), between patients abusing the so-called "dappou drugs" (designer drug in Japan, and those abusing methamphetamine (MAP). Both groups participated in the SMARPP at the Center Hospital, National Center of Neurology and Psychiatry. Results showed that, no significant differences were found in the rates of participation in the program or self-reported frequency of drug or alcohol use between the patients abusing "dappou drugs" or MAP. However, patients using "dappou drugs" reported no significant increase in their confidence in their ability to resist the temptation to use drugs on the self- report drug abuse scales after the SMARPP intervention, while patients abusing MAP reported a significant positive difference in their ability to resist temptation. In addition, insight into substance abuse problems and motivation to participate in further treatment slightly declined in those using "dappou drugs," while there was a significant increase reported by the patients using MAP. These results suggested that the SMARPP might not be as effective for patients abusing "dappou drugs" as for those abusing MAP. The development of a relapse prevention program specifically designed for patients abusing "dappou drugs" is required. PMID:25831947

    Single-nucleotide polymorphisms (SNPs) are the most common source of genetic variation within a species; however, few investigations demonstrate how naturally occurring SNPs may increase strain virulence. We recently used group A Streptococcus as a model pathogen to study bacteria strain genotype–patient disease phenotype relationships. Whole-genome sequencing of approximately 800 serotype M59 group A Streptococcus strains, recovered during an outbreak of severe invasive infections across North America, identified a disproportionate number of SNPs in the gene encoding multiple gene regulator of group A Streptococcus (mga). Herein, we report results of studies designed to test the hypothesis that the most commonly occurring SNP, encoding a replacement of arginine for histidine at codon 201 of Mga (H201R), significantly increases virulence. Whole transcriptome analysis revealed that the H201R replacement significantly increased expression of mga and 54 other genes, including many proven virulence factors. Compared to the wild-type strain, a H201R isogenic mutant strain caused significantly larger skin lesions in mice. Serial quantitative bacterial culture and noninvasive magnetic resonance imaging also demonstrated that the isogenic H201R strain was significantly more virulent in a nonhuman primate model of joint infection. These findings show that the H201R replacement in Mga increases the virulence of M59 group A Streptococcus and provide new insight to how a naturally occurring SNP in bacteria contributes to human disease phenotypes.

    Objective To compare clinical features and functional outcomes of age and sex matched children with abusive and non-abusive head trauma receiving inpatient rehabilitation. Study design Children with abusive head trauma (n = 28) and age, sex matched children with non-abusive head trauma (n = 20) admitted to one inpatient pediatric rehabilitation unit from 1995–2012 were studied. Acute hospitalization and inpatient rehabilitation records were retrospectively reviewed for pertinent clinical data: initial GCS score, signs of increased intracranial pressure, neuroimaging findings, and presence of associated injuries. Functional status at admission to and discharge from inpatient rehabilitation was assessed using the Functional Independence Measure for Children (WeeFIM). Outcome at discharge and outpatient follow-up was described based on attainment of independent ambulation and expressive language. Results Children with abusive and non-abusive head trauma had similar levels of injury severity although associated injuries were greater in abusive head trauma. Functional impairment upon admission to inpatient rehabilitation was comparable and functional gains during inpatient rehabilitation were similar between groups. More children with non-abusive than abusive head trauma attained independent ambulation and expressive language after discharge from rehabilitation; the difference was no longer significant when only children greater than 12 months of age at injury were examined. There was variability in delay to obtain these skills and quality of gained skills in both groups. Conclusions Despite more associated injuries, children with abusive head trauma make significant functional gains during inpatient rehabilitation comparable with an age and sex matched sample with non-abusive head trauma. Key functional skills may be gained by children in both groups following discharge from inpatient rehabilitation. PMID:24321537

    Low-income Latino immigrants are understudied in elder abuse research. Limited English proficiency, economic insecurity, neighborhood seclusion, a tradition of resolving conflicts within the family, and mistrust of authorities may impede survey research and suppress abuse reporting. To overcome these barriers, we recruited and trained promotores, local Spanish-speaking Latinos, to interview a sample of Latino adults age 66 and older residing in low-income communities. The promotores conducted door-to-door interviews in randomly selected census tracts in Los Angeles to assess the frequency of psychological, physical, and sexual abuse, financial exploitation, and caregiver neglect. Overall, 40.4% of Latino elders experienced some form of abuse and/or neglect within the previous year. Nearly 25% reported psychological abuse, 10.7% indicated physical assault, 9% reported sexual abuse, 16.7% indicated financial exploitation, and 11.7% were neglected by their caregivers. Younger age, higher education, and experiencing sexual or physical abuse before age 65 were significant risk factors for psychological, physical, and/or sexual abuse. Years lived in the United States, younger age, and prior abuse were associated with increased risk of financial exploitation. Years spent living in the U.S. was a significant risk factor for caregiver neglect. Abuse prevalence was much higher in all mistreatment domains than findings from previous research on community-dwelling elders, suggesting that low-income Latino immigrants are highly vulnerable to elder mistreatment, or that respondents are more willing to disclose abuse to promotores who represent their culture and community.

    The current study examined the rate and psychiatric correlates of sexual abuse involving the use of digital technologies by the offender in a wide sample of juvenile victims. Sociodemographic, abuse, and psychiatric characteristics of 662 sexually abused children and adolescents were evaluated. Of these, 93 reported that digital devices were used by the offender in several ways to facilitate the sexual abuse. The offender-victim relationship was initiated through the Internet in 39 victims. Involvement of digital technologies in sexual abuse was significantly associated with penetrative and recurrent form of sexual abuse commited by multiple offenders with coexisting violence. Additionally, victims of sexual abuse with a digital component were 4.21 times more likely to develop any psychopathology, 3.77 times more likely to have depression, and 2.14 times more likely to have post-traumatic stress disorder as a result of sexual abuse. These results indicated that the offender's use of digital technology may aid the initiation and facilitation of the sexual abuse of youths and may relate to more severe outcomes. This study revealed the importance of raising the awareness of professionals and the community about the potential risks associated with digital technologies and sexual abuse. Mental health professionals should consider this additional form of victimization, especially when dealing with sexual abuse victims. PMID:26075920

    Ketamine, a noncompetitive antagonist of the N-methyl-D-aspartate (NMDA) receptor, has multiple clinical uses. On the other hand, ketamine abuse or recreational use has been gaining increasing attention. Induction of mania and psychotic symptoms has been reported in a patient receiving IV ketamine therapy for reflex sympathetic dystrophy. We here report a 26 year-old man who abused ketamine by inhalation for 12 months and developed manic-like symptoms after ketamine use. This case suggests a possible relationship between manic symptoms and ketamine abuse. To the best of our knowledge, this may be the first report regarding mania after recreational use of ketamine.

    Background Few studies have explored the trends in central precocious puberty (CPP) in Asian populations. This study assessed the prevalence and annual incidence of CPP among Korean children. Methods Using data from the Korean Health Insurance Review Agency from 2004 to 2010, we reviewed the records of 21,351 children, including those registered with a diagnosis of CPP for the first time and those diagnosed with CPP who were treated with gonadotropin-releasing hormone analogs. Results The prevalence of CPP was 55.9 per 100,000 girls and 1.7 per 100,000 boys, respectively. The overall incidence of CPP was 15.3 per 100,000 girls, and 0.6 per 100,000 boys. The annual incidence of CPP in girls significantly increased from 3.3 to 50.4 per 100,000 girls; whereas in boys, it gradually increased from 0.3 to 1.2 per 100,000 boys. The annual incidence of CPP in girls consistently increased at all ages year by year, with greater increases at older ages (≥6 years of age), and smaller increases in girls aged < 6 years. In contrast, the annual incidence remained relatively constant in boys aged < 8 years, while a small increase was observed only in boys aged 8 years. The increase of annual incidence showed significant differences depending on age and gender (P <0.0001). Conclusions The annual incidence of CPP has substantially increased among Korean girls over the past 7 years. Continued monitoring of CPP trends among Korean children will be informative.

    In 1993, the U.S. Advisory Board on Child Abuse and Neglect declared a child protection emergency. Between 1985 and 1993, there was a 50 percent increase in reported cases of child abuse. Three million cases of child abuse are reported in the United States each year. Treatment of the abuser has had only limited success and child protection agencies are overwhelmed. Recently, efforts have begun to focus on the primary prevention of child abuse. Primary prevention of child abuse is defined as any intervention that prevents child abuse before it occurs. Primary prevention must be implemented on many levels before it can be successful. Strategies on the societal level include increasing the "value" of children, increasing the economic self-sufficiency of families, discouraging corporal punishment and other forms of violence, making health care more accessible and affordable, expanding and improving coordination of social services, improving the identification and treatment of psychologic problems, and alcohol and drug abuse, providing more affordable child care and preventing the birth of unwanted children. Strategies on the familial level include helping parents meet their basic needs, identifying problems of substance abuse and spouse abuse, and educating parents about child behavior, discipline, safety and development.

    Teachers are potentially helpful resource persons for large numbers of sexually abused children who may have difficulty disclosing abuse, particularly to family members. In the present study, the effectiveness of a 6-hour teacher training workshop on child sexual abuse prevention was evaluated. Responses of 26 female elementary teachers who participated in the workshop were compared to responses of 19 control teachers on several pre-, post-, and follow-up measures. Relative to controls, trained teachers demonstrated significant increases from pre- to post-testing in knowledge about child sexual abuse and pro-prevention opinions. On a post-only vignettes measure, trained teachers were better able than control teachers to identify behavioral indicators of abuse and suggest appropriate interventions for hypothetical sexually abused children. Over a 6-week follow-up period, trained teachers read more about child abuse than control teachers but did not differ on other behavioral dimensions such as reporting suspected abuse cases. Further research will examine the effects of additional teacher training over an extended follow-up period. PMID:3233520

    This study characterizes adults who report being physically abused during childhood, and examines associations of reported type and frequency of abuse with adult mental health. Data were derived from the 2000–2001 and 2004–2005 National Epidemiologic Survey on Alcohol and Related Conditions, a large cross-sectional survey of a representative sample (N = 43,093) of the U.S. population. Weighted means, frequencies, and odds ratios of sociodemographic correlates and prevalence of psychiatric disorders were computed. Logistic regression models were used to examine the strength of associations between child physical abuse and adult psychiatric disorders adjusted for sociodemographic characteristics, other childhood adversities, and comorbid psychiatric disorders. Child physical abuse was reported by 8% of the sample and was frequently accompanied by other childhood adversities. Child physical abuse was associated with significantly increased adjusted odds ratios (AORs) of a broad range of DSM-IV psychiatric disorders (AOR = 1.16–2.28), especially attention-deficit hyperactivity disorder, posttraumatic stress disorder, and bipolar disorder. A dose-response relationship was observed between frequency of abuse and several adult psychiatric disorder groups; higher frequencies of assault were significantly associated with increasing adjusted odds. The long-lasting deleterious effects of child physical abuse underscore the urgency of developing public health policies aimed at early recognition and prevention. PMID:22806701

    The aim of this study was to assess and contrast dissociation and posttraumatic stress disorder (PTSD) symptoms in a group of sexually abused school-aged girls compared with a matched group. Results from bivariate analyses show that the two symptom constellations represent distinct constructs. Logistic regression analysis indicates that sexual victimization significantly increases the odds of presenting with a clinical level of dissociation and PTSD symptoms, respectively, by eightfold and fourfold. On the basis of a multivariate design, abuse severity indicators, namely, penetration, relationship to perpetrator (intrafamilial versus extrafamilial abuse), and chronicity, did not prove predictive of dissociation symptoms. The least and the most severe forms of childhood sexual abuse both increase dissociative symptoms. The data indicate also that intrafamilial abuse and chronicity do not predict PTSD. However, abuse involving intrusive acts (penetration) does predict PTSD symptoms. Implications for intervention and further research are discussed. PMID:15674134

    This principle goal of this research was to examine the effects of various nanomaterials on the activity and behavior of the firefly enzyme luciferase. Nanomaterials have been found to stabilize, and in some instances, shown to increase the activity of enzymes. In this study gold, manganese oxide (MnO), and zinc oxide (ZnO) nanomaterials were utilized in order to test their effects on enzyme activity. Luciferase was used because its activity is easy to analyze, as it typically produces a large amount of bioluminescence easily detected by a Microtiter plate reader. Following incubation with the various nanomaterials, luciferase was subjected to degradation by several protein denaturing agents, such as heat, SDS, urea, ethanol, protease, hydrogen peroxide, and pH changes. Results indicated that luciferase activity is indeed affected when combined with nanomaterials, accompanied by both increases and decreases in enzyme activity depending on the type of nanomaterial and denaturing agent used. In most of the experiments, when incubated with ZnO nanomaterials, luciferase depicted significant increases in activity and bioluminescence. Additional experiments, in which human A375 cells were treated with luciferase-nanomaterial mixtures, also depicted increased enzyme activity and bioluminescence for luciferase incubated with ZnO nanomaterials. Ultimately, our findings indicated that when luciferase was subjected to multiple types of denaturation, zinc oxide nanomaterials dramatically preserved and increased enzyme activity and bioluminescence.

    Background: Alcohol and tobacco abuse are detrimental to general and oral health. Though the effects of these harmful habits on oral mucosa had been demonstrated, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. Materials and Methods: We compared 268 alcohol-only abusers with 2426 alcohol and tobacco abusers in chewing and smoking forms to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. Clinical examination, Decay, Missing, Filled Teeth (DMFT) Index and Oral Hygiene Index - Simplified were measured in a predetermined format. Descriptive statistics, Chi-square test and one-way ANOVA analysis were done using SPSS Version 16.0. Result: The mean DMFT were 3.31, 3.24, 4.09, 2.89 for alcohol-only abusers, alcohol and chewing tobacco abusers, smoking tobacco and alcohol abusers, and those who abused tobacco in smoke and smokeless forms respectively. There was no significant difference between the oral hygiene care measures between the study groups. Presence of attrition among chewers and those with extrinsic stains experienced less caries than others. Discussion and conclusion: The entire study population exhibited a higher incidence of caries experience. Use of tobacco in any form appears to substantially increase the risk for dental caries. Attrition with use of chewing tobacco and presence of extrinsic stains with tobacco use appear to provide a protective effect from caries. The changes in oral micro-flora owing to tobacco use and alcohol may play a critical role in the initiation and progression of dental caries. PMID:21731272

    The sexual abuses described in this article are occurring so frequently that they constitute a public health problem. Superficially they appear to be quite dissimilar because they involve individuals of different ages, different settings, and different power relationships. Basic to each of them, however, is an absence of consent by the victim and the misuse of power by the perpetrator in order to accomplish the abuse. We now have an adequate understanding of each of these abuses and it is now time to make a concerted effort to stop these abuses. This will require the combined efforts of the education of the public, improved identification of the abuses, treatment of the victims, and an appropriate criminal justice response combined with treatment of the perpetrator.

    The aim of this study was to identify variables that distinguish mothers who broke the cycle of abuse from mothers who were abused as children and who also abused their own children. Based on maternal interviews and questionnaires completed over a 64-month period, measures of mothers' past and current relationship experiences, stressful life events, and personality characteristics were obtained. Abused mothers who were able to break the abusive cycle were significantly more likely to have received emotional support from a nonabusive adult during childhood, participated in therapy during any period of their lives, and to have had a nonabusive and more stable, emotionally supportive, and satisfying relationship with a mate. Abused mothers who reenacted their maltreatment with their own children experienced significantly more life stress and were more anxious, dependent, immature, and depressed. PMID:3168615

    This study sought to examine (a) a mediational model of childhood abuse, adult interpersonal abuse, and depressive symptoms and (b) the impact of weight-related teasing on rates and correlates of childhood abuse. Charts of 187 extremely obese individuals seeking psychological clearance for bariatric (weight-loss) surgery were retrospectively examined. Among the participants, 61% reported a history of childhood abuse, 30.5% reported adult interpersonal abuse, and 15% reported clinically significant depressive symptoms. Initially, the relationship between childhood abuse and current depressive symptoms was significant (p<.001). However, the introduction of adult interpersonal abuse as a mediator in the model reduced the magnitude of its significance (Sobel's test p=.01). The associations between childhood abuse and adult interpersonal abuse and between adult interpersonal abuse and depressive symptoms were significant (p<.001 and p=.002, respectively), and the model showed a good fit across multiple indices. Finally, weight-related teasing was a significant moderator in the relationship between childhood and adult interpersonal abuse. Bariatric surgery patients report elevated rates of childhood abuse that are comparable to rates in psychiatric populations (e.g., eating disorders, depression), and higher than those in community samples and other medical populations. The relationship between child abuse and depressive symptomatology may be partially explained by the presence of adult interpersonal abuse; additionally, the relationship between childhood and adult interpersonal abuse was stronger for those who did not endure weight-related teasing than for those who did.

    Previous studies have shown that glial cell line-derived neurotrophic factor (GDNF) exerts significant neuroprotective effects on substantia nigra (SN) neurons in the rat 6-hydroxydopamine (6-OHDA) model of Parkinson's disease (PD). In this study we used enzyme-linked immunosorbent assay (ELISA) to determine GDNF brain levels and distribution to target regions (i.e. striatum and SN) following intranasal administration of GDNF at different time points after administration. Brain levels increased significantly within 1h following a single 50-μg dose of GDNF in a liposomal formulation, returning to baseline by 24h. In a second study, different doses of GDNF (10-150 μg) in phosphate-buffered saline (PBS) were studied at the 1-h time point. Dose-dependent increases in brain GDNF levels were observed with apparent saturation of uptake at doses above 100 μg. Liposomes delivered 10-fold more GDNF to brain than PBS despite yielding similar neuroprotective efficacy in the 6-OHDA model, suggesting incomplete release of GDNF from liposomes in tissue. In a third study, autoradiography was performed on brain sections taken 1h after intranasal (125)I-labeled GDNF. Radioactivity was detected throughout the brain along the rostral-to-caudal axis, indicating that nasally administered GDNF can reach target areas. Collectively, these results demonstrate that intranasal administration of GDNF in liposomes or PBS achieves significant increases in GDNF in target brain areas, supporting use of intranasal administration as a non-invasive means of delivering GDNF to the brain to protect dopamine neurons and arrest disease progression in PD.

    An increasing human population requires more food production in nutrient-efficient systems in order to simultaneously meet global food needs while reducing the environmental footprint of agriculture. Arbuscular mycorrhizal fungi (AMF) have the potential to enhance crop yield, but their efficiency has yet to be demonstrated in large-scale crop production systems. This study reports an analysis of a dataset consisting of 231 field trials in which the same AMF inoculant (Rhizophagus irregularis DAOM 197198) was applied to potato over a 4-year period in North America and Europe under authentic field conditions. The inoculation was performed using a liquid suspension of AMF spores that was sprayed onto potato seed pieces, yielding a calculated 71 spores per seed piece. Statistical analysis showed a highly significant increase in marketable potato yield (ANOVA, P < 0.0001) for inoculated fields (42.2 tons/ha) compared with non-inoculated controls (38.3 tons/ha), irrespective of trial year. The average yield increase was 3.9 tons/ha, representing 9.5 % of total crop yield. Inoculation was profitable with a 0.67-tons/ha increase in yield, a threshold reached in almost 79 % of all trials. This finding clearly demonstrates the benefits of mycorrhizal-based inoculation on crop yield, using potato as a case study. Further improvements of these beneficial inoculants will help compensate for crop production deficits, both now and in the future. PMID:26403242

    Oxygen coordination of transition metals is a key for functional properties of transition-metal oxides, because hybridization of transition-metal d and oxygen p orbitals determines correlations between charges, spins and lattices. Strain often modifies the oxygen coordination environment and affects such correlations in the oxides, resulting in the emergence of unusual properties and, in some cases, fascinating behaviors. While these strain effects have been studied in many of the fully-oxygenated oxides, such as ABO3 perovskites, those in oxygen-deficient oxides consisting of various oxygen coordination environments like tetrahedra and pyramids as well as octahedra remain unexplored. Here we report on the discovery of a strain-induced significant increase, by 550 K, in the metal-insulator transition temperature of an oxygen-deficient Fe oxide epitaxial thin film. The observed transition at 620 K is ascribed to charge disproportionation of Fe3.66+ into Fe4+ and Fe3+, associated with oxygen-vacancy ordering. The significant increase in the metal-insulator transition temperature, from 70 K in the bulk material, demonstrates that epitaxial growth of oxygen-deficient oxides under substrate-induced strain is a promising route for exploring novel functionality.

    Research highlights: {yields} Aging is associated with muscle atrophy and loss of muscle mass, known as the sarcopenia of aging. {yields} We demonstrate that age-related muscle atrophy is associated with marked changes in miRNA expression in muscle. {yields} Treating aged mice with the adipokine leptin significantly increased muscle mass and the expression of miRNAs involved in muscle repair. {yields} Recombinant leptin therapy may therefore be a novel approach for treating age-related muscle atrophy. -- Abstract: Age-associated loss of muscle mass, or sarcopenia, contributes directly to frailty and an increased risk of falls and fractures among the elderly. Aged mice and elderly adults both show decreased muscle mass as well as relatively low levels of the fat-derived hormone leptin. Here we demonstrate that loss of muscle mass and myofiber size with aging in mice is associated with significant changes in the expression of specific miRNAs. Aging altered the expression of 57 miRNAs in mouse skeletal muscle, and many of these miRNAs are now reported to be associated specifically with age-related muscle atrophy. These include miR-221, previously identified in studies of myogenesis and muscle development as playing a role in the proliferation and terminal differentiation of myogenic precursors. We also treated aged mice with recombinant leptin, to determine whether leptin therapy could improve muscle mass and alter the miRNA expression profile of aging skeletal muscle. Leptin treatment significantly increased hindlimb muscle mass and extensor digitorum longus fiber size in aged mice. Furthermore, the expression of 37 miRNAs was altered in muscles of leptin-treated mice. In particular, leptin treatment increased the expression of miR-31 and miR-223, miRNAs known to be elevated during muscle regeneration and repair. These findings suggest that aging in skeletal muscle is associated with marked changes in the expression of specific miRNAs, and that nutrient

    AIM: To determine the significance of increased serum direct bilirubin level for lymph node metastasis (LNM) in Chinese rectal cancer patients, after those with known hepatobiliary and pancreatic diseases were excluded. METHODS: A cohort of 469 patients, who were treated at the China-Japan Friendship Hospital, Ministry of Health (Beijing, China), in the period from January 2003 to June 2011, and with a pathological diagnosis of rectal adenocarcinoma, were recruited. They included 231 patients with LNM (49.3%) and 238 patients without LNM. Follow-up for these patients was taken through to December 31, 2012. RESULTS: The baseline serum direct bilirubin concentration was (median/inter-quartile range) 2.30/1.60-3.42 μmol/L. Univariate analysis showed that compared with patients without LNM, the patients with LNM had an increased level of direct bilirubin (2.50/1.70-3.42 vs 2.10/1.40-3.42, P = 0.025). Multivariate analysis showed that direct bilirubin was independently associated with LNM (OR = 1.602; 95%CI: 1.098-2.338, P = 0.015). Moreover, we found that: (1) serum direct bilirubin differs between male and female patients; a higher concentration was associated with poor tumor classification; (2) as the baseline serum direct bilirubin concentration increased, the percentage of patients with LNM increased; and (3) serum direct bilirubin was associated with the prognosis of rectal cancer patients and higher values indicated poor prognosis. CONCLUSION: Higher serum direct bilirubin concentration was associated with the increased risk of LNM and poor prognosis in our rectal cancers. PMID:26937145

    Engineered antibody domains (eAds) are promising candidate therapeutics but their half-life is relatively short partly due to weak or absent binding to the neonatal Fc receptor (FcRn). We developed a novel approach to increase the eAd binding to FcRn based on a combination of structure-based design, computational modeling and phage display methodologies. By using this approach, we identified 2 IgG1 CH2-derived eAds fused to a short FcRn-binding motif derived from IgG1 CH3 that exhibited greatly enhanced FcRn binding with strict pH dependency. Importantly, the increased affinity resulted in significantly enhanced FcRn-mediated epithelial transcytosis and prolonged elimination half-life (mean 44.1 hours) in cynomolgus macaques. These results demonstrate for the first time that the half-life of isolated eAds can be prolonged (optimized) by increasing their binding to FcRn while maintaining their small size, which has important implications for development of therapeutics, including eAd-drug conjugates with enhanced penetration in solid tissues.

    Axonal extension is influenced by a variety of external guidance cues; therefore, the development and optimization of a multi-faceted approach is probably necessary to address the intricacy of functional regeneration following nerve injury. In this study, primary dissociated neonatal rat dorsal root ganglia neurons and Schwann cells were examined in response to an 8 h dc electrical stimulation (0-100 mV mm-1). Stimulated samples were then fixed immediately, immunostained, imaged and analyzed to determine Schwann cell orientation and characterize neurite outgrowth relative to electric field strength and direction. Results indicate that Schwann cells are viable following electrical stimulation with 10-100 mV mm-1, and retain a normal morphology relative to unstimulated cells; however, no directional bias is observed. Neurite outgrowth was significantly enhanced by twofold following exposure to either a 50 mV mm-1 electric field (EF) or co-culture with unstimulated Schwann cells by comparison to neurons cultured alone. Neurite outgrowth was further increased in the presence of simultaneously applied cues (Schwann cells + 50 mV mm-1 dc EF), exhibiting a 3.2-fold increase over unstimulated control neurons, and a 1.2-fold increase over either neurons cultured with unstimulated Schwann cells or the electrical stimulus alone. These results indicate that dc electric stimulation in combination with Schwann cells may provide synergistic guidance cues for improved axonal growth relevant to nerve injuries in the peripheral nervous system.

    Elder abuse is a tragedy both for the individual and for society because it occupies a pivotal position in the family life cycle of violence. Great variety exists among victims, abusers, and situations; thus, no single model is adequate to explain cause and direct treatment. Primary care physicians must be alert to the possibility of elder abuse in their patients and aware of resources within their community for managing cases once identified. Federal laws and regulations must take a proactive, long-term approach to the solution of this problem and must respect the autonomy of competent elderly patients. PMID:8356158

  5. HIV-1 Structural Proteins Serve as PAMPs for TLR2 Heterodimers Significantly Increasing Infection and Innate Immune Activation

    Immune activation is critical to HIV infection and pathogenesis; however, our understanding of HIV innate immune activation remains incomplete. Recently we demonstrated that soluble TLR2 (sTLR2) physically inhibited HIV-induced NFκB activation and inflammation, as well as HIV-1 infection. In light of these findings, we hypothesized that HIV-1 structural proteins may serve as pathogen-associated molecular patterns (PAMPs) for cellular TLR2 heterodimers. These studies made use of primary human T cells and TZMbl cells stably transformed to express TLR2 (TZMbl-2). Our results demonstrated that cells expressing TLR2 showed significantly increased proviral DNA compared to cells lacking TLR2, and mechanistically this may be due to a TLR2-mediated increased CCR5 expression. Importantly, we show that HIV-1 structural proteins, p17, p24, and gp41, act as viral PAMPs signaling through TLR2 and its heterodimers leading to significantly increased immune activation via the NFκB signaling pathway. Using co-immunoprecipitation and a dot blot method, we demonstrated direct protein interactions between these viral PAMPs and TLR2, while only p17 and gp41 bound to TLR1. Specifically, TLR2/1 heterodimer recognized p17 and gp41, while p24 lead to immune activation through TLR2/6. These results were confirmed using TLR2/1 siRNA knock down assays which ablated p17 and gp41-induced cellular activation and through studies of HEK293 cells expressing selected TLRs. Interestingly, our results show in the absence of TLR6, p24 bound to TLR2 and blocked p17 and gp41-induced activation, thus providing a novel mechanism by which HIV-1 can manipulate innate sensing. Taken together, our results identified, for the first time, novel HIV-1 PAMPs that play a role in TLR2-mediated cellular activation and increased proviral DNA. These findings have important implications for our fundamental understanding of HIV-1 immune activation and pathogenesis, as well as HIV-1 vaccine development. PMID:26347747

    Electric field measurements of skin potential and electrical currents are physiological indicators of electrodermal activity (EDA) and have been associated with a variety of sensory, cognitive and emotional stimuli. The aim of this study was to investigate the EDA at some hand acupoints before, during and after a physical exercise. EDA of eight points located at the corner of fingernails of hands was measured in 10 healthy young volunteers before, during and after a 14-min acute exercise in a bicycle ergometer. In pre-exercise resting state the parameters were stable and similar between the 8 different tested points, while during exercise a significant increase of current (from 1000-2000 to 4000-8000 nA) was observed, with the maximal values related to the point located on the ulnar side of the little finger, at the base of the nail, corresponding to the Shao chong (HT9) of heart meridian.

    Purpose: To ascertain whether the time from injury to prophylactic radiation therapy (RT) influences the rate of heterotopic ossification (HO) after operative treatment of displaced acetabular fractures. Methods and Materials: This is a single-institution, retrospective analysis of patients referred for RT for the prevention of HO. Between January 2000 and January 2009, 585 patients with displaced acetabular fractures were treated surgically followed by RT for HO prevention. We analyzed the effect of time from injury on prevention of HO by RT. In all patients, 700 cGy was prescribed in a single fraction and delivered within 72 hours postsurgery. The patients were stratified into five groups according to time interval (in days) from the date of their accident to the date of RT: Groups A {<=}3, B {<=}7, C {<=}14, D {<=}21, and E >21days. Results: Of the 585 patients with displaced acetabular fractures treated with RT, (18%) 106 patients developed HO within the irradiated field. The risk of HO after RT increased from 10% for RT delivered {<=}3 days to 92% for treatment delivered >21 days after the initial injury. Wilcoxon test showed a significant correlation between the risk of HO and the length of time from injury to RT (p < 0.0001). Chi-square test and multiple logistic regression analysis showed no significant association between all other factors and the risk of HO (race, gender, cause and type of fracture, surgical approach, or the use of indomethacin). Conclusions: Our data suggest that there is higher incidence and risk of HO if prophylactic RT is significantly delayed after a displaced acetabular fracture. Thus, RT should be administered as early as clinically possible after the trauma. Patients undergoing RT >3 weeks from their displaced acetabular fracture should be informed of the higher risk (>90%) of developing HO despite prophylaxis.

    Accumulating evidence supports the existence of cancer stem cells (CSCs) in human tumors, and the successful certification of CSCs may lead to the identification of therapeutic targets, which are more effective for the treatment of cancer. The use of spherical cancer models has increased in popularity in cancer stem cell investigations. Tumorospheres, which are used as a model of CSCs and are established in serum‑free medium supplemented with growth factors under non‑adherent conditions, are one of the most commonly used cancer spherical models and are a valuable method for enriching the CSC fraction. To investigate whether this model is applicable in lung cancer (LC), the identification of lung CSCs and their capacities is essential. In the present study, lung CSCs were enriched by sphere-forming culturing and their stem‑like properties were assessed. The results indicated that the lung tumorospheres had enhanced proliferation, clonality, invasion and cisplatin‑resistance, and showed significantly increased expression levels of CD133 and breast cancer resistance protein (ABCG2). These results, together with findings previously reported in literature, indicated that the sphere‑forming culturing of LC cells induced the enrichment of CSCs and that the tumorospheres exhibited stem cell characteristics. In addition, the higher expression levels of CD133 and ABCG2 in the tumorospheres may provide a rationale for therapeutic targets for LC. PMID:27432082

    2015-04-01

    An important new landmark in present day ozone research is presented through MLS satellite observations of significant ozone increases during the ozone hole season that are attributed unequivocally to declining ozone depleting substances. For many decades the Antarctic ozone hole has been the prime example of both the detrimental effects of human activities on our environment as well as how to construct effective and successful environmental policies. Nowadays atmospheric concentrations of ozone depleting substances are on the decline and first signs of recovery of stratospheric ozone and ozone in the Antarctic ozone hole have been observed. The claimed detection of significant recovery, however, is still subject of debate. In this talk we will discuss first current uncertainties in the assessment of ozone recovery in the Antarctic ozone hole by using multi-variate regression methods, and, secondly present an alternative approach to identify ozone hole recovery unequivocally. Even though multi-variate regression methods help to reduce uncertainties in estimates of ozone recovery, great care has to be taken in their application due to the existence of uncertainties and degrees of freedom in the choice of independent variables. We show that taking all uncertainties into account in the regressions the formal recovery of ozone in the Antarctic ozone hole cannot be established yet, though is likely before the end of the decade (before 2020). Rather than focusing on time and area averages of total ozone columns or ozone profiles, we argue that the time evolution of the probability distribution of vertically resolved ozone in the Antarctic ozone hole contains a better fingerprint for the detection of ozone recovery in the Antarctic ozone hole. The advantages of this method over more tradition methods of trend analyses based on spatio-temporal average ozone are discussed. The 10-year record of MLS satellite measurements of ozone in the Antarctic ozone hole shows a

    Background Light fractionation significantly increases the efficacy of 5-aminolevulinic acid (ALA) based photodynamic therapy (PDT) using the nano-emulsion based gel formulation BF-200. PDT using BF-200 ALA has recently been clinically approved and is under investigation in several phase III trials for the treatment of actinic keratosis. This study is the first to compare BF-200 ALA with ALA in preclinical models. Results In hairless mouse skin there is no difference in the temporal and spatial distribution of protoporphyrin IX determined by superficial imaging and fluorescence microscopy in frozen sections. In the skin-fold chamber model, BF-200 ALA leads to more PpIX fluorescence at depth in the skin compared to ALA suggesting an enhanced penetration of BF-200 ALA. Light fractionated PDT after BF-200 ALA application results in significantly more visual skin damage following PDT compared to a single illumination. Both ALA formulations show the same visual skin damage, rate of photobleaching and change in vascular volume immediately after PDT. Fluorescence immunohistochemical imaging shows loss of VE-cadherin in the vasculature at day 1 post PDT which is greater after BF-200 ALA compared to ALA and more profound after light fractionation compared to a single illumination. Discussion The present study illustrates the clinical potential of light fractionated PDT using BF-200 ALA for enhancing PDT efficacy in (pre-) malignant skin conditions such as basal cell carcinoma and vulval intraepithelial neoplasia and its application in other lesion such as cervical intraepithelial neoplasia and oral squamous cell carcinoma where current approaches have limited efficacy.

    Introduction: In this study the induction of bone formation in an axially vascularized bone matrix using mesenchymal stem cells (MSCs) and application of bone morphogenetic protein 2 (BMP2) was analyzed in the arteriovenous loop (AVL) model. Materials and Methods: An AVL was created in the medial thigh of 42 rats and placed in a porous titanium chamber filled with a particulated porous hydroxyapatite and beta-tricalcium phosphate matrix and fibrin. In group A the fibrin was loaded with 5×106 DiI-stained fibrin gel-immobilized primary MSCs from syngenic Lewis rats, in group B the matrix was loaded with 60 μg/mL BMP2 and in group C both, BMP2 and MSCs were applied at implantation time point. After 6 and 12 weeks, specimens were investigated by means of histological, morphometrical, and micro-computed tomography analysis. Results: After implantation of an AVL a dense vascular network was visible in all groups. In group A, newly generated bone islands were detected in the periphery of the main vascular axis. Using BMP2 alone (group B), small islands of newly formed bone were visible evenly distributed in all parts of the constructs. In group C nearly the whole matrix was interspersed with bone formations. In all groups there was an increase of bone formation between the 6 and 12 weeks explantation time points. Conclusions: This study demonstrates for the first time the successful generation of axially vascularized bone substitutes using MSCs and BMP2 in the AVL rat model using a one step procedure. Using the combination of BMP2 and MSCs there was a significant increase of bone formations detectable compared to the BMP2 or MSCs alone groups. PMID:25135080

    Objective: Clonidine, an alpha-2 adrenergic agonist, increases the quality of perioperative sedation and analgesia with a few side effects. This study was designed to assess the effect of clonidine premedication on the anesthesics used for elective below knee surgeries in opium abusers and non-abusers. Materials and Methods: In a randomized clinical trial, 160 patients were selected and assigned into four groups. Eighty patients among the opium abusers were divided randomly into clonidine and no clonidine groups, with 40 patients in each, and 80 among the non-abusers were again divided randomly into clonidine and no clonidine groups, with 40 patients in each group. All were anesthetized for elective orthopedic operation using the same predetermined method. The total administered dose of propofol and other variables were compared. Results: The total propofol dose in a decreasing order was as follows: Abuser patients receiving placebo (862 ± 351 mg), non-abuser patients receiving placebo (806 ± 348 mg), abuser patients receiving clonidine (472 ± 175 mg), and non-abuser patients receiving clonidine (448 ± 160 mg). Hence, a statistically significant difference was observed among the four study groups (P value for ANOVA = 0.0001). Conclusion: Adding clonidine as a preoperative medication decreases the patient's anesthetic needs; this decrease was even more considerable on the anesthetic needs than the effect of opium abuse history on anesthetic dose.

The objective of this article is to share the knowledge gained within the Clinical Trials Network (CTN) of the National Institute on Drug Abuse and other research on recruiting and retaining ethnic minorities into substance abuse clinical trials. The article includes a discussion of two broad areas for improving inclusion— community involvement and cultural adaptation. CTN case studies are included to illustrate three promising strategies for improving ethnic minority inclusion: respondent-driven sampling, community-based participatory research, and the cultural adaptation of the recruitment and retention procedures. The article concludes with two sections describing a number of methodological concerns in the current research base and our proposed research agenda for improving ethnic minority inclusion that builds on the CTN experience.

    Background Child abuse continues to be a social menace causing both physical and emotional trauma to benevolent children. Census has shown that nearly 50–75% of child abuse include trauma to mouth, face, and head. Thus, dental professionals are in strategic position to identify physical and emotional manifestations of abuse. Aim A cross-sectional survey was undertaken to assess knowledge and attitude of dental practitioners regarding child abuse and to identify the barriers in reporting the same. Methods With prior consent, a 20-question survey including both multiple choice and dichotomous (Yes/No) questions was mailed to 120 state-registered general dentists, and the data collected were subjected to statistical analysis. Results Overall response rate to the questionnaires was 97%. Lack of knowledge about dentist's role in reporting child abuse accounted to 55% in the reasons for hesitancy to report. Pearson chi-square test did not show any significant difference between male and female regarding reason for hesitancy to report and legal obligation of dentists. Conclusion Although respondent dentists were aware of the diagnosis of child abuse, they were hesitant and unaware of the appropriate authority to report. Increased instruction in the areas of recognition and reporting of child abuse and neglect should be emphasized. PMID:27195209

    Abusive Head Trauma (AHT) is a form of child physical abuse that involves inflicted injury to the brain and its associated structures. Abusive Head Trauma, colloquially called Shaken Baby Syndrome, is the most common cause of serious or fatal brain injuries in children aged 2 years and younger. The American Academy of Pediatrics recommends the term Abusive Head Trauma, as opposed to Shaken Baby Syndrome, as the former term encompasses multiple forms of inflicted head injury (inertial, contact, and hypoxic-ischemic) and a range of clinical presentations and radiologic findings and their sequelae. Children diagnosed with AHT are 5 times more likely to die compared with accidentally head-injured children, yet signs and symptoms are not always obvious, and therefore the diagnosis can be overlooked. Therefore, the American Academy of Pediatrics has tasked pediatricians with knowing how and when to begin an evaluation of children with signs and symptoms that could possibly be due to AHT. Overall, a detailed history of present illness and medical history, recognition of physical and radiological findings, and careful interpretation of retinal pathology are important aspects of formulating the differential diagnoses and increasing or decreasing the index of suspicion for AHT.

    Background Limited research has shown a possible association between exposure to physical or sexual abuse prior to age 18 and the risk of developing hypertension as an adult. The factors mediating this relationship are unknown. Methods We analyzed questionnaire data from 68 505 female participants in the Nurses’ Health Study II regarding exposure to physical and sexual abuse prior to age 18. Cox proportional hazards regression was used to assess the relationship between abuse exposure and hypertension. Results Sixty-four percent of the participants (n = 41 792) reported physical and/or sexual abuse prior to age 18; 17% reported hypertension. All forms of abuse had a dose-response relationship with hypertension. Adjustments for smoking, alcohol, family history of hypertension, exercise, and oral contraceptives did not alter risk estimates. Adjustment for body mass index (BMI) significantly attenuated the associations between abuse and risk of hypertension and accounted for approximately 50% of the observed association between abuse exposure and hypertension. Women experiencing forced sexual activity as a child and as an adolescent had a 20% increased risk for developing hypertension (95% CI 8–32%) that was independent of BMI. Similarly, women reporting severe physical abuse in childhood and/or adolescence had risk estimates ranging from 14% (95% CI 5–24%) to 22% (95% CI 11–33%). Conclusion Early interpersonal violence may be a widespread risk factor for the development of hypertension in women. BMI is a significant mediator in the relationship between early abuse and adult hypertension. PMID:20445210

  1. Six Year Refractive Change among White Children and Young Adults: Evidence for Significant Increase in Myopia among White UK Children

    2016-01-01

    Objective To determine six-year spherical refractive error change among white children and young adults in the UK and evaluate differences in refractive profiles between contemporary Australian children and historical UK data. Design Population-based prospective study. Participants The Northern Ireland Childhood Errors of Refraction (NICER) study Phase 1 examined 1068 children in two cohorts aged 6–7 years and 12–13 years. Prospective data for six-year follow-up (Phase 3) are available for 212 12–13 year olds and 226 18–20 year olds in each cohort respectively. Methods Cycloplegic refractive error was determined using binocular open-field autorefraction (Shin-Nippon NVision-K 5001, cyclopentolate 1%). Participants were defined by spherical equivalent refraction (SER) as myopic SER ≤-0.50D, emmetropic -0.50Dsignificantly increased between 6–7 years (1.9%) and 12–13 years (14.6%) (p<0.001) but not between 12–13 and 18–20 years (16.4% to 18.6%, p = 0.51). The estimated annual incidence of myopia was 2.2% and 0.7% for the younger and older cohorts respectively. There were significantly more myopic children in the UK at age 12–13 years in the NICER study (16.4%) than reported in Australia (4.4%) (p<0.001). However by 17 years the proportion of myopia neared equivalence in the two populations (NICER 18.6%, Australia 17.7%, p = 0.75). The proportion of myopic children aged 12–13 years in the present study (2006–2008) was 16.4%, significantly greater than that reported for children aged 10–16 years in the 1960’s (7.2%, p = 0.01). The proportion of hyperopes in the younger NICER cohort decreased significantly over the six year period (from 21.7% to 14.2%, p = 0.04). Hyperopes with SER ≥+3.50D in both NICER age cohorts demonstrated persistent hyperopia. Conclusions The incidence and proportion of myopia are relatively

    This study investigates the relationship between discrimination and substance abuse among Latina/os, and further examines whether this relationship differs by gender and type of discrimination. Analyses focus on the Latina/o respondents (n = 1,039 men; n = 1,273 women) from the National Latino and Asian American Study carried out from 2002-2003. Outcomes were alcohol abuse and drug abuse measured using DSM-IV definitions and criteria. Additional covariates included immigrant characteristics and demographics. Analyses were completed using gender-stratified multinomial logistic regression. Men reported more discrimination (39.6% vs. 30.3%) and had higher prevalence of alcohol abuse (16.5% vs. 4.5%) and drug abuse (9.5% vs. 2.3%) than women. Discrimination was significantly associated with increased risk of alcohol abuse for women and increased risk of drug abuse for men. Men and women also varied in the types of discrimination (e.g., racial vs. gender) reported, and in the associations between these types of discrimination and substance abuse. These data indicate that discrimination is associated with different substance abuse outcomes between genders. Future research should consider the mechanisms that explain these differences.

    Systemic inflammation and immune response were associated with prognosis of tumors. However, data was limited due to the relatively low incidence of gastrointestinal stromal tumors (GISTs). The aim of the present study was to investigate the predictive value of preoperative peripheral blood cells in prognosis of GISTs.From September 2008 to July 2015, a total of 274 GIST patients in our department were enrolled in the present study. Clinicopathological features of GISTs were recorded. The association between preoperative peripheral blood cells and prognosis of GISTs were analyzed.Tumor location, tumor size, mitotic index, intratumoral necrosis, and National Institutes of Health (NIH) risk category were associated with prognosis of GISTs. High neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-white blood cell ratio (NWR), monocyte-to-white blood cell ratio (MWR) and low lymphocyte-to-white blood cell ratio (LWR) was associated with poor prognosis of GISTs (76.2% vs 83.7%, P = 0.010. 70.5% vs 98.7%, P = 0.000. 65.7% vs 96.4%, P = 0.004. 78.5% vs 82.5%, P = 0.044. 73.5% vs 97.8%, P = 0.004. 76.6% vs 83.6%, P = 0.012, respectively). However, tumor size was the only independent risk factor for prognosis according to multivariate analysis (P = 0.006). Tumor location, tumor size, mitotic index, and NIH risk category were significantly correlated with the above-mentioned parameters (all P < 0.05). The prognosis of GISTs with tumor size >5 cm, high MLR, high PLR, and high MWR was significantly lower than the remnant patients (P = 0.010).The peripheral blood routine test is convenient, reproducible, and inexpensive. High NLR, MLR, PLR, NWR, MWR, and low LWR were associated with poor prognosis of GISTs. The association between the above parameters and prognosis of GISTs may be attributed to their correlation with tumor size, mitotic index, and NIH risk category. The

    The purpose of this study is to use a modified version of Andersen’s (1968, 1995) Behavioral Model of Health Services Use to identify the correlates of the number of substance abuse treatment episodes received by rural drug users. Data were collected from face-to-face interviews with 711 drug users in rural areas of Ohio, Arkansas, and Kentucky. Descriptive analyses examine rural drug users’ substance use histories and retrospective substance abuse treatment service utilization patterns. A negative binomial regression model indicated that selected predisposing, historical health, and enabling factors were significantly associated with the utilization of substance abuse treatment among rural drug users. Despite high levels of recent and lifetime self-reported substance use among these rural drug users, treatment services were underutilized. Future studies are needed to examine the impact of the health care system and characteristics of the external environment associated with rural substance abuse treatment in order to increase utilization among drug users.

    While serious questions have arisen concerning the validity of Freud's seduction theory of neurosis, a related issue concerns the extent to which Freud, following the abandonment of the seduction theory, may have misinterpreted real memories of sexual abuse as imaginary. Certain theoretical statements by Freud as well as his advice to Jung concerning a 6-yr.-old patient who had accused her foster-father of sexual abuse indicate that he may have been significantly biased toward interpreting certain types of incest allegations as fantasies. Increased awareness of Freud's biases, both in his early tendency to pressure patients into believing that they were victims of abuse and in his later tendency to regard certain types of incest allegations as unreal, may contribute to a more objective approach to the diagnosis and treatment of sexual abuse in the future.

    The primary objectives of this study were to determine the prevalence of nonconvulsive seizures and nonconvulsive status epilepticus in patients with abusive head trauma who underwent electroencephalography (EEG) monitoring and to describe predictive factors for this population. Children with a diagnosis of abusive head trauma were studied retrospectively to determine the rate of EEG monitoring, the rate of nonconvulsive seizures and nonconvulsive status epilepticus, and the associated neuroimaging findings. Over 11 years, 73 of 199 (36.8%) children with abusive head trauma had electroencephalography monitoring performed. Of these, 20 (27.4%) had nonconvulsive seizures and 3 (4.1%) had nonconvulsive status epilepticus. The presence of subarachnoid hemorrhage and cortical T2 / fluid-attenuated inversion recovery signal abnormalities were both significantly associated with the presence of nonconvulsive seizures / nonconvulsive status epilepticus. Nonconvulsive seizures are relatively common in abusive head trauma and may go unrecognized. Specific neuroimaging characteristics increase the likelihood of nonconvulsive seizures on EEG.

    This study investigated the characteristics of abuse suffered by children, the dimensions of the psychiatric effects associated with abuse, and the factors affecting these. One thousand two cases aged under 18, exposed to sexual abuse, and referred over a 7-year period were assessed. Girls represented 80.8% of cases, and the numbers rose with age. The aggressors were all male, and 88.2% were known to their victim. Approximately half the children were exposed to sexual abuse involving penetration. Psychological pathology was identified in 62.1%. Female gender, the presence of penetration, physical violence, and incest significantly increased the development of psychological pathology. Levels of awareness in people close to and trusted by the child must be raised to minimize the adverse effects of trauma in the long term, preventive measures must be taken, and medical and social support units from which victims can receive assistance need to be established.

    1998-06-01

    A population-based descriptive investigation of housefire accidents in Denmark was carried out for the two five year periods 1953-58 and 1988-93, based on death certificates, police reports and autopsy reports. The number of deaths due to housefire accidents in Denmark has increased (1953-58: 136 (66 men and 70 women), 1988-93: 363 (212 men and 150 women), mostly due to an increase in tobacco-smoking related fire accidents. In 1988-93 the three common causes of housefire deaths were tobacco-smoking, often in combination with alcohol intoxication or handicap (51%), cooking-accidents (10%) and accidents with candles (9%). The largest risk groups were chronic alcoholics, handicapped and elderly people. In conclusion, warnings should be issued against smoking in bed and use of loose-fitting clothing while cooking on an open fire. Protective aprons and devices for use while smoking, self-extinguishing cigarettes and use of fireproof materials in furniture and clothing may prevent ignition. Smoke-alarms may secure early warning. PMID:9627509

    It is widely believed that young mothers are at greater risk of engaging in physical abuse. However, this relationship is not clearly supported by previous empirical research. This study reexamines the issue using a nationally representative sample of 1,997 mothers. All analyses controlled for family income, race, number of minor children in the home, age of abused child, mother's education, and whether mother was a single parent. Physical abuse was measured with the Conflict Tactics Scales. Using mother's age at time of birth of the abused child, the younger the mother, the greater the rate of child abuse; however, there was not a significant relationship when mother's age was measured at age at time of abuse. Large families and minority group children were also found to be at greater risk of abuse. The paper discusses implications for further research and for prevention of child abuse. PMID:1393729

    Based on daily 500 hPa heights from ERA-Interim reanalysis, this study analyzed the day-to-day circulation variance in cold season (October-March) during the global-warming hiatus by employing composite and correlation analysis. Two same-length time periods, i.e., the hiatus period (1999-2013) and the rapid warming period (1984-1998), are compared. Spectral analysis reveals that over the mid-high latitude northern hemisphere the most outstanding peak in the daily 500hPa height variance is of quasi bi-weekly (QBW) time scale (about 10-20d), which accounts for about 32% of the total variance. During the global-warming hiatus, the QBW disturbances have changed remarkably in Northeast Asia. On average in the domain of 128°E-142°E, 42°N-50°N the QBW variance has changed from 1860m2 in the rapid warming period to 2475m2 in the hiatus, increasing by about 33% and being statistically significant at the 95% level. The time-lag analysis shows that the QBW signal could be traced back to about 14 days ago with a origin around Ural Mountains, then the signals developed and moved southeastward, its location about 10 days ago was located in West Siberia, about 6 days ago located in Mongolian Plat. at finally move to Northeast Asia. Compared the propagation process between the two periods, we found that the path was basically the same, but there are evident difference in their signal intensity along its eastward propagation. Comparing with the rapid warm period, the QBW during the hiatus got much intensive as the signal move across the West Siberia. And the enhanced signal keeps its intensity till to Northeast Asia. The intensification of QBW may be related to the changes in the background circulation. During the hiatus period, there are anomalous large-scale changes in 500hPa heights, with a strengthened Ural ridge and a westward East Asia trough. Accordingly, there is a stronger east-west pressure gradient in western Siberia, being a condition beneficial to strengthen the

    Women living in poor urban communities are doubly disadvantaged with regard to increased risk for two major public health crises in the United States today--HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome) and violence. This study moves beyond the comparison of rates of lifetime abuse among women to incorporate contextual information of the abusive situation and experiences of HIV-positive women and a sample of sociodemographically similar HIV-negative women. A total of 611 women, 310 of whom were diagnosed as HIV positive, provided interviews integrating quantitative data and qualitative text on their lifetime experience of abuse. Quantitative results yielded few statistically significant differences between the lifetime experiences of violence between HIV-positive women and their HIV-negative counterparts. Of the women, 62% reported intimate partner violence, and 38% reported experiencing nonpartner abuse as an adult. A majority of the abused women reported that their alcohol or drug use or their partner's alcohol or drug use was associated with the abuse experienced. Significant differences were found between HIV-positive women and HIV-negative women in the pattern of abuse experienced as a child, the frequency of abuse as an adult, and the involvement of women's drinking before or during a violent episode. Qualitative excerpts from the interviews were found to differ thematically and were integrated with the quantitative data to provide a more comprehensive understanding of the women's contextual situation in understanding interpersonal violence experienced by both HIV-positive and HIV-negative women.

    Objective To examine the association between childhood abuse/neglect and central adiposity and obesity in a sample of 311 women (106 Black, 205 White) from the Pittsburgh site of the Study of Women's Health Across the Nation (SWAN). Methods SWAN included a baseline measurement of women in midlife (mean age = 45.7) and 8 follow-up visits during which waist circumference (WC) and body mass index (BMI) were measured. The Childhood Trauma Questionnaire retrospectively assessed emotional, physical, and sexual abuse and emotional and physical neglect in childhood. Results ANCOVA analyses showed that women with a history of any abuse/neglect, and specifically physical and sexual abuse, had significantly higher WC and BMI at baseline than women with no abuse history. A significant interaction between abuse and BMI showed that among women with BMI < 30, any abuse/neglect and certain subtypes of abuse predicted greater increases in WC over time. Additional analyses showed that Trait Anger scores and sex hormone-binding globulin (SHBG) attenuated cross-sectional relationships between abuse/neglect and WC and BMI. Conclusion This study suggests that abused/neglected women appear to have greater anger and lower levels of SHBG, which are associated with adiposity in mid-life. PMID:20064904

    Elder abuse, also called elder mistreatment or elder maltreatment, includes psychological, physical, and sexual abuse, neglect (caregiver neglect and self-neglect), and financial exploitation. Evidence suggests that 1 out of 10 older adults experiences some form of elder abuse, and only a fraction of cases are actually reported to social services agencies. At the same time, elder abuse is independently associated with significant morbidity and premature mortality. Despite these findings, there is a great paucity in research, practice, and policy dealing with this pervasive issue. In this paper, I review the epidemiology of elder abuse as well as key practical issues in dealing with the cases of elder abuse. Through my experiences as a Congressional Policy Fellow/National Health and Aging Policy Fellow, I highlight key previsions on 2 major federal legislations dealing with the issues of elder abuse: Older Americans Act (OAA) and Elder Justice Act (EJA). Lastly, I highlight major research gaps and future policy relevant research directions to advance the field of elder abuse. Interdisciplinary and community-based efforts are needed to devise effective strategies to detect, treat, and prevent elder abuse in our increasingly diverse aging populations. Collective advocacy and policy advances are needed to create a national infrastructure to protect the vulnerable older adults. PMID:24270215

    Objective. The goal of this study was to examine the monthly incidence rates of abusive encounters for family physicians in Canada. Methods. A 7-page cross-sectional survey. Results. Of the entire study sample (N = 720), 29% of the physicians reported having experienced an abusive event in the last month by a patient or patient family member. Abusive incidents were classified as minor, major, or severe. Of the physician participants who reported having been abused, all reported having experienced a minor event, 26% a major, and 8% a severe event. Of the physicians who experienced an abusive event, 55% were not aware of any policies to protect them, 76% did not seek help, and 64% did not report the abusive event. Conclusion. Family physicians are subjected to significant amounts of abuse in their day-to-day practices. Few physicians are aware of workplace policies that could protect them, and fewer report abusive encounters. Physicians would benefit from increased awareness of institutional policies that can protect them against abusive patients and their families and from the development of a national policy.

    Objectives. We examined the social and interpersonal context of gender abuse and its effects on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition major depression among transgender women. Methods. We conducted a 3-year prospective study (2004–2007) among 230 transgender women aged 19 to 59 years from the New York City Metropolitan Area. Statistical techniques included generalized estimating equations (logistic regression). Results. We observed significant associations of psychological and physical gender abuse with major depression during follow-up. New or persistent experiences of both types of abuse were associated with 4- to 7-fold increases in the likelihood of incident major depression. Employment, transgender presentation, sex work, and hormone therapy correlated across time with psychological abuse; the latter 2 variables correlated with physical abuse. The association of psychological abuse with depression was stronger among younger than among older transgender women. Conclusions. Psychological and physical gender abuse is endemic in this population and may result from occupational success and attempts to affirm gender identity. Both types of abuse have serious mental health consequences in the form of major depression. Older transgender women have apparently developed some degree of resilience to psychological gender abuse.

    Drug abuse with illicit drugs and licit drugs has been increasing steadily over the past decade. A recent National Household Survey on Drug Abuse found statistically significant increases between 2000 and 2001 in the use of multiple drugs, including marijuana, cocaine, and non-medical use of pain relievers and tranquilizers. Prescription controlled substance abuse is a major issue in chronic pain management. Various means suggested to avoid or monitor abuse in patients in treatment include urine/serum drug screening whenever requested, along with other precautions including one prescribing physician and one designated pharmacy, etc. Based on the present evidence, physicians assume that patients adhering to controlled substance agreements and without obvious dependency behavior do not abuse either illicit or licit drugs. Thus, it is accepted that there is no necessity to perform routine urine/drug testing in this specific group of the patient population. One hundred patients undergoing interventional pain management and receiving controlled substances were randomly selected for evaluation of illicit drug abuse by urine drug testing. They were selected from a total of 250 patients who were identified as non-abusers of prescription drugs. Results showed that illicit drug abuse in patients without history of controlled substance abuse was seen in 16 patients. Thirteen of the 16 patients tested positive for marijuana and 3 patients tested positive for cocaine. Only one patient tested positive for a combined use of both marijuana and cocaine. This study showed that, in an interventional pain management setting, there is significant use of illicit drugs (16%) with 13% use of marijuana and 3% use of cocaine in patients who are considered as non-abusers of prescription controlled substances and those who are adherent to controlled substance agreements. However, if cocaine is considered as a hardcore drug in contrast to marijuana, abuse of hardcore illicit drugs is only 3

    The investigation of short time dynamics using X-ray scattering techniques is commonly limited either by the read out frequency of the detector or by a low intensity. In this paper, we present a chopper system, which can increase the temporal resolution of 2D X-ray detectors by a factor of 13. This technique only applies to amorphous or polycrystalline samples due to their circular diffraction patterns. Using the chopper, we successfully increased the temporal resolution up to 5.1 ms during synchrotron experiments. For the construction, we provide a mathematical formalism, which, in principle, allows an even higher increase of the temporal resolution.

    Most sexual offense research focuses on offender motivation and individual risk factors rather than the criminal events themselves. This article provides an analysis of data from two studies on child sexual abuse by Catholic priests to help understand the opportunities clergy had or created to abuse youth. Findings show that situational factors played a role in victim choice among a heterogeneous group of abusers. Priests abused more male than female victims and had significantly greater access to male youth historically. When access to female youth increased in the 1990s, abuse of females as a percentage of victims also increased. The article concludes with a discussion about how ecological information can be used to craft intervention policies to prevent sexual offenses. PMID:22809048

    Nearly 1 in 5 girls and 1 in 20 boys under the age of 18 will be the victim of child sexual abuse. As adults, these individuals are more likely to report myriad mental illnesses including depression. Testing the hypothesis that having children would moderate the depressive effects of child sexual abuse, the authors used public-use data of the National Longitudinal Study of Adolescent Health Wave IV (n = 5,114; mean age = 29.00 years; SD = 1.78). Results indicate that having children significantly moderates the relationship between child sexual abuse and depression for females. Though the risk of depression is increased for all females with a child sexual abuse history, this increase is less dramatic for mothers. Two potential explanations of this effect are presented: biological and psychosocial. The possible implications for mental health professionals working with mothers with a child sexual abuse history include highlighting the role of their children as possible support. PMID:26340070

    Many adult survivors of childhood abuse hide their victimization, avoiding disclosure that could identify perpetrators, end the abuse, and bring help to the victim. We surveyed 1,679 women undergraduates to understand disclosure of childhood sexual, physical, and emotional abuse, and, for the first time, witnessed domestic violence, which many consider to be emotionally abusive. A substantial minority of victims failed to ever disclose their sexual abuse (23%), physical abuse (34%), emotional abuse (20%), and witnessed domestic violence (29%). Overall, abuse-specific factors were better predictors of disclosure than individual-level characteristics. Disclosure of sexual abuse was related to experiencing more frequent abuse (by the same and by multiple perpetrators), being more worried about injury and more upset at the time of the abuse, and self-labeling as a victim of abuse. Disclosure of physical abuse was related to experiencing more frequent abuse (by the same and multiple perpetrators), being less emotionally close to the perpetrator, being older when the abuse ended, being more worried and upset, and self-labeling as a victim. Disclosure of emotional abuse was associated with being older when the abuse ended, and being more worried and upset. Disclosure was unrelated to victim demographic characteristics or defensive reactions (dissociative proneness, fantasy proneness, repressive coping style, and temporary forgetting), except that among physical and emotional abuse victims, repressors were less likely to disclose than non-repressors. Disclosure of witnessing domestic violence was not significantly related to any factors measured. PMID:25550167

    Distinguishing authentic abuse from false memory among adults who recover memories of childhood sexual trauma has far-reaching significance. This study initially examined 13 previously reported Rorschach signs of sexual abuse in women not abused, and women sexually abused (and not amnestic). The abuse signs were more prevalent in the abused group. A sexual abuse index composed of 8 signs correctly classified 93% of the abused, and 98% of the nonabused group. The index was then applied to women who recovered memories of abuse; some had analogues of dissociation in their protocols and others did not. Those exhibiting dissociative signs produced more signs of sexual abuse. The index classified 88% of the dissociative group as abused, but only 24% of the nondissociative group. The relevance of these findings for assessing authenticity of recovered memories is explored. PMID:8827651

    Over the last 20 years, diminishing tolerance for domestic violence has triggered significant criminal justice reforms designed to facilitate the prosecution of abusers. Prosecutors, for example, have adopted policies requiring that cases go forward even if the victim later has second thoughts. Although increasingly common, these "no drop" policies reflect a profound irony about domestic cases that is well known but little understood: the most formidable problem in prosecuting such cases is often the victim's own unwillingness to bring the abuser to justice. This prospective study explored a range of factors potentially predictive of domestic violence victims' cooperation with the prosecution of their abusers. Although the study focused on interpersonal and institutional social support, it also investigated the influence of violence severity, victim demographic factors, and victim mental health characteristics, including the presence of depressive symptoms, emotional dependence on the abuser, and substance abuse. Findings showed that tangible support, severity of violence in the relationship, and the presence of children in common with the abuser all significantly predicted victims' cooperation with the prosecution of their abusers. Substance abuse significantly predicted victims' noncooperation with prosecution. The research and policy implications of these findings are discussed. PMID:10751049

    Domestic abuse is increasingly recognised as a serious, worldwide public health concern. There is a significant body of literature regarding domestic abuse, but little is known about health professionals' beliefs about domestic abuse disclosure. In addition, the intersection between health professionals' beliefs and abused women's views remains uninvestigated. We report on a two-phase, qualitative study using Critical Incident Technique (CIT) that aimed to explore community health professionals' beliefs about domestic abuse and the issue of disclosure. We investigated this from the perspectives of both health professionals and abused women. The study took place in Scotland during 2011. The study was informed theoretically by the Common Sense Model of Self-Regulation of Health and Illness (CSM). This model is typically used in disease-orientated research. In our innovative use, however, CSM was used to study the social phenomenon, domestic abuse. The study involved semi-structured, individual CIT interviews with health professionals and focus groups with women who had experienced domestic abuse. Twenty-nine health professionals (Midwives, Health Visitors and General Practitioners) participated in the first phase of the study. In the second phase, three focus groups were conducted with a total of 14 women. Data were analysed using a combination of an inductive classification and framework analysis. Findings highlight the points of convergence and divergence between abused women's and health professionals' beliefs about abuse. Although there was some agreement, they do not always share the same views. For example, women want to be asked about abuse, but many health professionals do not feel confident or comfortable discussing the issue. Overall, the study shows the dynamic interaction between women's and health professionals' beliefs about domestic abuse and readiness to discuss and respond to it. Understanding these complex dynamics assists in the employment of

    The influences of parental divorce and alcohol abuse on adult offspring lifetime suicide attempt have not been examined in national data. This study analyzed data from the 2001-2002 NESARC to estimate main and interaction effects of parental divorce and alcohol abuse on lifetime suicide attempt. Adjusted for controls, parental divorce and parental alcohol abuse independently increased odds of lifetime suicide attempt. The effect of parental divorce was not significantly moderated by parental alcohol abuse. Further research is needed to examine whether additional parental and offspring psychiatric and substance use covariates attenuate the association between parental divorce and lifetime suicide attempt.

    This prospective study aimed to investigate the prognostic significance of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) as a non-invasive imaging technique delivering the quantitative parameters amplitude A (reflecting blood volume) and exchange rate constant kep (reflecting vascular permeability) in patients with asymptomatic monoclonal plasma cell diseases. We analysed DCE-MRI parameters in 33 healthy controls and 148 patients with monoclonal gammopathy of undetermined significance (MGUS) or smouldering multiple myeloma (SMM) according to the 2003 IMWG guidelines. All individuals underwent standardized DCE-MRI of the lumbar spine. Regions of interest were drawn manually on T1-weighted images encompassing the bone marrow of each of the 5 lumbar vertebrae sparing the vertebral vessel. Prognostic significance for median of amplitude A (univariate: P < 0·001, hazard ratio (HR) 2·42, multivariate P = 0·02, HR 2·7) and exchange rate constant kep (univariate P = 0·03, HR 1·92, multivariate P = 0·46, HR 1·5) for time to progression of 79 patients with SMM was found. Patients with amplitude A above the optimal cut-off point of 0·89 arbitrary units had a 2-year progression rate into symptomatic disease of 80%. In conclusion, DCE-MRI parameters are of prognostic significance for time to progression in patients with SMM but not in individuals with MGUS. PMID:26991959

    Child sexual abuse (CSA) continues to be a significant problem with significant short and long term consequences. However, extant literature is limited by the reliance on retrospective recall of adult samples, single-time assessments, and lack of longitudinal data during the childhood and adolescent years. The purpose of this study was to compare internalizing and externalizing behavior problems of those with a history of sexual abuse to those with a history of maltreatment, but not sexual abuse. We examined whether gender moderated problems over time. Data were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) at ages 4, 6, 8, 10, 12, 14, and 16 (N=977). The Child Behavior Checklist was used to assess internalizing and externalizing problems. Maltreatment history and types were obtained from official Child Protective Services (CPS) records. Generalized Estimating Equations (GEE) were used to assess behavior problems over time by maltreatment group. Findings indicated significantly more problems in the CSA group than the maltreated group without CSA over time. Internalizing problems were higher for sexually abused boys compared to girls. For sexually abused girls internalizing problems, but not externalizing problems increased with age relative to boys. This pattern was similar among maltreated but not sexually abused youth. Further efforts are needed to examine the psychological effects of maltreatment, particularly CSA longitudinally as well as better understand possible gender differences in order to best guide treatment efforts.

  14. Abuse and toxicity of methylphenidate.

    PubMed

    Klein-Schwartz, Wendy

    2002-04-01

    The therapeutic use of methylphenidate for the management of attention-deficit hyperactivity disorder in children is increasing. As therapeutic use increases, the risk increases of unintentional overdoses, medication errors, and intentional overdoses caused by abuse, misuse, or suicide gestures and attempts. Side effects during therapy, which include nervousness, headache, insomnia, anorexia, and tachycardia, increase linearly with dose. Clinical manifestations of overdoses include agitation, hallucinations, psychosis, lethargy, seizures, tachycardia, dysrhythmias, hypertension, and hyperthermia. Methylphenidate tablets can be abused orally, or they can be crushed and the powder injected or snorted. Despite its abuse potential, there is disagreement regarding the extent to which methylphenidate is being diverted from legitimate use to abuse in preteens and adolescents. PMID:11981294

    Social relationships and interactions contribute to daily emotional well-being. The emotional benefits that come from engaging with others are known to arise from real events, but do they also come from the imagination during daydreaming activity? Using experience sampling methodology with 101 participants, we obtained 371 reports of naturally occurring daydreams with social and non-social content and self-reported feelings before and after daydreaming. Social, but not non-social, daydreams were associated with increased happiness, love and connection and this effect was not solely attributable to the emotional content of the daydreams. These effects were only present when participants were lacking in these feelings before daydreaming and when the daydream involved imagining others with whom the daydreamer had a high quality relationship. Findings are consistent with the idea that social daydreams may function to regulate emotion: imagining close others may serve the current emotional needs of daydreamers by increasing positive feelings towards themselves and others.

    OBJECTIVE--To assess whether the increased prevalence of trisomy 21 in West Berlin in January 1987 might have been causally related to exposure to ionising radiation as a result of the Chernobyl reactor accident or was merely a chance event. DESIGN--Analysis of monthly prevalence of trisomy 21 in West Berlin from January 1980 to December 1989. SETTING--Confines of West Berlin. RESULTS--Owing to the former "island" situation of West Berlin and its well organised health services, ascertainment of trisomy 21 was thought to be almost complete. A cluster of 12 cases occurred in January 1987 as compared with two or three expected. After exclusion of factors that might have explained the increase, including maternal age distribution, only exposure to radiation as a result of the Chernobyl reactor accident remained. In six of seven cases that could be studied cytogenetically the extra chromosome was of maternal origin, confirming that nondisjunction had occurred at about the time of conception. CONCLUSION--On the basis of two assumptions--(a) that maternal meiosis is an error prone process susceptible to exogenous factors at the time of conception; (b) that owing to the high prevalence of iodine deficiency in Berlin a large amount of iodine-131 would have been accumulated over a short period--it is concluded that the increased prevalence of trisomy 21 in West Berlin in January 1987 was causally related to a short period of exposure to ionising radiation as a result of the Chernobyl reactor accident.

    Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated. PMID:2582695

    The article focuses on countries and areas of South-East Asia, which are seriously affected by drug abuse and the problems associated with it. Opium has traditionally been used for treating illnesses and alleviating physical and mental stress, as well as for recreational and social purposes. The prohibition of the sale and use of opium in Burma, Hong Kong, Malaysia, Singapore and Thailand forced many habitual opium users to switch to heroin. Over the past two decades there has been an increasing trend towards drug use, often involving experimentation with more than one substance, among youth in and out of school. For example, a survey of students at teachers' colleges in northern Thailand showed that at some time in their lives 30-40 per cent of the male respondents and 3-6 per cent of the female respondents had used cannabis, and that 18-20 per cent of the males and 12-27 per cent of the females had sniffed volatile solvents. The same survey showed that 5-10 per cent of both the males and females had used stimulants and nearly 2 per cent had used heroin. During the 1970s the abuse of heroin and other opiates emerged as a serious problem of epidemic nature, predominantly affecting young people in many countries of South-East Asia. While opiates, including heroin, have been abused by inhaling and by smoking, there has recently been an increasing trend towards injecting heroin of high purity (80-90 per cent pure heroin). Heroin addiction spread first to the populations of capital cities and then to other cities and towns and even to the hill tribes, as studies in Thailand have revealed. Most recent studies have shown that heroin abuse has spread further in Asia, both socially and geographically, involving such countries as India and Sri Lanka, which had no previous experience with the problem. Studies have also shown that the abuse of manufactured psychotropic substances has been increasing and that heroin addicts resort to these substances when heroin is difficult

    This article discusses abuse and neglect of elderly women in Ghana and the traditional practices that adversely affect their human rights. Their situation is characterized by pervasive poverty, illiteracy, widowhood, predominantly rural dwelling, and subjection to insidious cultural practices and superstitious beliefs. Increase in life expectancy and population trends point to significant increases in the numbers of the elderly women. Breakdown of the extended family support system and the waning of filial obligations are factors affecting their welfare. Accurate data on these abuses is lacking due to cultural inhibitions and non-reporting. Legislations and NGO programs are addressed to combat abuses. PMID:26362126

    BACKGROUND In spite of the increasing trend in opioid abusers worldwide, the prevalence of narcotic bowel syndrome (NBS) is undetermined. We aimed to estimate the prevalence of NBS and other opioid bowel dysfunction (OBD) in opioid abusers in Kerman, southeast Iran. According to the best of our knowledge, this is the first study to assess the prevalence of NBS in opioid abusers. METHODS By referring to addiction treatment centers in Kerman city and in a cross-sectional study, 577 subjects with opium or opioid subtracts abuse were included in our study. A validated questionnaire was used for OBD assessment and diagnosis of NBS was made according to both the presence of chronic abdominal pain despite increasing the opioid dose and ruling out other causes of abdominal pain. SPSS software version 16 was used for data analysis. p value<0.05 was considered as statistically significant. RESULTS Constipation, regurgitation, and heartburn were the most gastrointestinal complaints that were found in 132(22.9%), 123(21.3%) and 91(15.8%) subjects, respectively. Only 16(2.8%) participants fulfilled all the NBS criteria. Simultaneous use of non-narcotic sedative drugs increased the risk of NBS significantly (the odds ratio 3:1 and p=0.049). CONCLUSION NBS is not rare among opioid abusers and should be considered as a cause of chronic abdominal pain in this group. PMID:25349684

    This article provides an ecological framework for understanding adolescent-initiated parent abuse. We review research on adolescent-initiated parent abuse, identifying sociodemographic characteristics of perpetrators and victims (e.g., gender, age, race/ethnicity, and socioeconomic status [SES]). Bronfenbrenner's [1] ecological systems theory is applied, which examines the risk and protective factors for adolescent-initiated parent abuse within micro- (maltreatment, domestic violence, parenting behavior and disciplinary strategies), meso- (peer influence), exo- (media influence), macro- (gender role socialization), and chronosystem (change in family structure) levels. Findings from our review suggest that older and White children are significantly more likely to abuse their parents. Females are selective in the target of their aggression, while males target family members in general. Mothers are significantly more likely to be abused than fathers. However, researchers also report variations in the association between SES and parent abuse. Domestic violence and child maltreatment are risk factors, while findings on parenting behavior and disciplinary strategies are mixed. Peer influence, exposure to media violence, gender role socialization, and change in family structure can potentially increase the risk of parent abuse. Practice and research implications are also discussed. An ecological systems framework allows for an examination of how various contexts interact and influence parent abuse behavior, and can provide needed directions for further research. PMID:22160270

    Objectives. As part of the World Health Organization's cross-national research effort, we investigated the relationship between various health indicators and the experience of intimate partner violence (IPV), which included emotional, physical, and sexual abuse, among women in Yokohama, Japan. Methods. We used multivariate logistic and negative binomial regression to examine the relationship between health status and IPV in a stratified cluster sample of 1371 women aged 18 to 49 years. Results. In 9 of 11 health indicators examined, the odds of experiencing health-related problems were significantly higher (P < .05) among those that reported emotional abuse plus physical or sexual violence than among those that reported no IPV, after we controlled for sociodemographic factors, childhood sexual abuse, and adulthood sexual violence perpetrated by someone other than an intimate partner. For most health indicators, there were no significant differences between those that reported emotional abuse only and those that reported emotional abuse plus physical or sexual violence. Conclusions. The similarity of outcomes among those that reported emotional abuse only and those that reported emotional abuse plus physical or sexual violence suggests the need for increased training of health care providers about the effects of emotional abuse.

    Standard hematological indices are commonly used in malaria epidemiological studies to measure anemia prevalence and calculate blood parasite densities. In Africa, few studies have investigated how these indices change during a malaria transmission season and with increasing age. To address these knowledge gaps, we collected blood from 169 healthy Malian children aged 3-12 years before (May 2010) and after (January 2011) a transmission season. Red blood cell (RBC) count, hemoglobin (Hb) level, hematocrit (Ht), white blood cell (WBC) count, and WBC subsets were measured in paired blood samples, and the data were stratified by month (May, January) and age group (3-5, 6-8, and 9-12 years). From May to January, RBC count (4.53-4.70 × 10(6)/μL; P < 0.0001), Hb level (11.5-11.9 g/dL; P < 0.0001), and Ht (37.1-39.2%; P < 0.0001) increased, and WBC count (6.46-5.96 × 10(3)/μL; P = 0.0006) decreased. From May to January, the prevalence of WBC subsets also changed: 35-43% neutrophils, 6.5-7.6% monocytes, and 53-45% lymphocytes (P < 0.001). These seasonal changes were not associated with the number of malaria episodes experienced in the interim or the presence of RBC polymorphisms. In May, Hb (11.2, 11.4, and 11.8 g/dL; P = 0.0013) and Ht (36.5%, 36.7%, and 38.1%; P = 0.0154) increased and WBC count (8.04, 6.43, and 5.76 × 10(3)/μL; P < 0.0001) decreased with age group; similar differences were observed in January. These data suggest that season- and age-based reference values for hematological indices are needed to better estimate anemia prevalence and parasite density in malaria epidemiological studies.

    Chemotherapy-induced broad toxicities are the leading cause of the drug-induced mortality in cancer patients. Antiangiogenic drugs (ADs) in combination with chemotherapy are widely used as front-line therapy for the treatment of various human cancers. However, the beneficial mechanisms underlying combination therapy are poorly understood. Here we show that, in several murine tumor models, administration of sunitinib markedly reduced chemotherapy-induced bone marrow toxicity. Intriguingly, in a sequential treatment regimen, delivery of ADs followed by chemotherapy demonstrated superior survival benefits compared with simultaneous administration of two drugs. In murine tumor models, we show that VEGF increased chemotoxicity by synergistically suppressing bone marrow hematopoiesis with cytostatic drugs. These findings shed light on molecular mechanisms by which ADs in combination with chemotherapy produce survival benefits in cancer patients and provide conceptual information guiding future designs of clinical trials, current practice, and optimization of ADs for the treatment of cancer.

    This study investigates the relationship between discrimination and substance abuse among Latina/os, and further examines whether this relationship differs by gender and type of discrimination. Analyses focus on the Latina/o respondents (n=1,039 men; n=1,273 women) from the National Latino and Asian American Study carried out from 2002–2003. Outcomes were alcohol abuse and drug abuse measured using DSM-IV definitions and criteria. Additional covariates included immigrant characteristics and demographics. Analyses were completed using gender-stratified multinomial logistic regression. Men reported more discrimination (39.6% versus 30.3%) and had higher prevalence of alcohol abuse (16.5% versus 4.5%) and drug abuse (9.5% versus 2.3%) than women. Discrimination was significantly associated with increased risk of alcohol abuse for women and increased risk of drug abuse for men. Men and women also varied in the types of discrimination (e.g. racial versus gender) reported, and in the associations between these types of discrimination and substance use. These data indicate that discrimination is associated with different substance abuse outcomes between genders. Future research should consider the mechanisms that explain these differences.

    We sought to determine whether maternal (a) physical harm from intimate partner abuse during pregnancy or (b) sexual, emotional, or physical abuse before birth increased risk of autism spectrum disorder. We calculated risk ratios for autism spectrum disorder associated with abuse in a population-based cohort of women and their children (54,512 controls, 451 cases). Physical harm from abuse during pregnancy was not associated with autism spectrum disorder. However, autism spectrum disorder risk was increased in children of women who reported fear of partner or sexual, emotional, or physical abuse in the 2 years before the birth year (abuse in the year before the birth year: risk ratio = 1.58, 95% confidence interval = 1.04, 2.40; abuse in both of the 2 years before the birth year: risk ratio = 2.16, 95% confidence interval = 1.33, 3.50). Within-family results were similar, although did not reach statistical significance. Association of intimate partner abuse before the child's birth year with autism spectrum disorder in the child was not accounted for by gestation length, birth weight, maternal smoking or alcohol consumption during pregnancy, gestational diabetes, preeclampsia, or history of induced abortion.

    The dental profession has a legal, ethical and moral responsibility to report suspected cases of abuse and neglect. The risk to the child is significant. In non-fatal cases of abuse, 35 percent will be abused again within one year. To this end, dentists should discuss child abuse and neglect at staff meetings and establish office procedures if a case is identified.

  10. Growth hormone significantly increases the adult height of children with idiopathic short stature: comparison of subgroups and benefit

    PubMed Central

    2014-01-01

    Background Children with Idiopathic Short Stature do not attain a normal adult height. The improvement of adult height with treatment with recombinant human growth hormone (rhGH), at doses of 0.16 to 0.28 mg/kg/week is modest, usually less that 4 cm, and they remain short as adults. The benefit obtained seems dose dependent and benefits of 7.0 to 8.0 cm have been reported with higher doses of 0.32 to 0.4 mg/kg/week, but the number of studies is limited. The topic has remained controversial. Objective The objective was to conduct a retrospective analysis of our experience with 123 children with ISS treated with 0.32 ± 0.03 mg/kg/week of rhGH, with the aim of comparing the different subgroups of non-familial short stature, familial short stature, normal puberty, and delayed puberty and to assess the benefit by comparison with 305 untreated historical controls, from nine different randomized and nonrandomized controlled studies. Results Eighty eight of our children (68 males and 20 females) attained an adult height or near adult height of -0.71 SDS (0.74 SD) (95% CI, -0.87 to -0.55) with a benefit over untreated controls of 9.5 cm (7.4 to 11.6 cm) for males and 8.6 cm (6.7 to 10.5 cm) for females. In the analysis of the subgroups, the adult height and adult height gain of children with non-familial short stature were significantly higher than of familial short stature. No difference was found in the cohorts with normal or delayed puberty in any of the subgroups, except between the non-familial short stature and familial short stature puberty cohorts. This has implications for the interpretation of the benefit of treatment in studies where the number of children with familial short stature in the controls or treated subjects is not known. The treatment was safe. There were no significant adverse events. The IGF-1 values were essentially within the levels expected for the stages of puberty. Conclusion Our experience was quite positive with normalization of

    Abuse of prescription opioid medications has increased dramatically in the U.S. during the past decade, as indicated by a variety of epidemiological sources. However, few studies have systematically examined the relative reinforcing effects of commonly abused opioid medications. The current double-blind, placebo-controlled inpatient study was designed to compare the effects of intravenously delivered fentanyl (0, 0.0625, 0.125, 0.187, and 0.250 mg/70 kg), oxycodone (0, 6.25, 12.5, 25, and 50 mg/70 kg), morphine (0, 6.25, 12.5, 25, and 50 mg/70 kg), buprenorphine (0, 0.125, 0.5, 2, and 8 mg/70 kg), and heroin (0, 3.125, 6.25, 12.5, and 25 mg/70 kg) in morphine-maintained heroin abusers (N=8 completers maintained on 120 mg per day oral morphine in divided doses [30 mg q.i.d.]). All of the participants received all of the drugs tested; drugs and doses were administered in non-systematic order. All of the drugs produced statistically significant, dose-related increases in positive subjective ratings, such as “I feel a good drug effect” and “I like the drug.” In general, the order of potency in producing these effects, from most to least potent, was: fentanyl > buprenorphine ≥ heroin > morphine = oxycodone. In contrast, buprenorphine was the only drug that produced statistically significant increases in ratings of “I feel a bad drug effect” and it was the only drug that was not self-administered above placebo levels at any dose tested. These data suggest that the abuse liability of buprenorphine in heroin-dependent individuals may be low, despite the fact that it produces increases in positive subjective ratings. The abuse liabilities of fentanyl, morphine, oxycodone, and heroin, however, appear to be similar under these experimental conditions. PMID:17581533

    Aims Evidence-based changes planned for DSM-5 substance use disorders (SUDs) include combining dependence and three of the abuse criteria into one disorder and adding a criterion indicating craving. Because DSM-IV did not include a category for nicotine abuse, little empirical support is available for aligning the nicotine use disorder criteria with the DSM-5 criteria for other SUDs. Design Latent variable analyses, likelihood ratio tests (LRT) and bootstrap tests were used to explore the unidimensionality, psychometric properties and information of the nicotine criteria. Setting, Participants A sample of household residents selected from the Israeli population register yielded 727 lifetime cigarette smokers. Measurements DSM-IV nicotine dependence criteria and proposed abuse and craving criteria, assessed with a structured interview. Findings Three abuse criteria (hazardous use, social/interpersonal problems, and neglect roles) were prevalent among smokers, formed a unidimensional latent trait with nicotine dependence criteria, were intermixed with dependence criteria across the severity spectrum, and significantly increased the diagnostic information over the dependence-only model. LRT results also supported including the abuse criteria (Χ23=259.63, p<0.0001). A craving criterion was shown to fit well with the other criteria. Conclusion Similar to findings from research on other substances, nicotine dependence, abuse, and craving criteria formed a single factor. The results support alignment of nicotine criteria with those for alcohol and drug use disorders in DSM-5. PMID:21545668

    Environmental (i.e., meteorological and landscape) factors and management practices can affect the prevalence of foodborne pathogens in produce production environments. This study was conducted to determine the prevalence of Listeria monocytogenes, Listeria species (including L. monocytogenes), Salmonella, and Shiga toxin-producing Escherichia coli (STEC) in produce production environments and to identify environmental factors and management practices associated with their isolation. Ten produce farms in New York State were sampled during a 6-week period in 2010, and 124 georeferenced samples (80 terrestrial, 33 water, and 11 fecal) were collected. L. monocytogenes, Listeria spp., Salmonella, and STEC were detected in 16, 44, 4, and 5% of terrestrial samples, 30, 58, 12, and 3% of water samples, and 45, 45, 27, and 9% of fecal samples, respectively. Environmental factors and management practices were evaluated for their association with terrestrial samples positive for L. monocytogenes or other Listeria species by univariate logistic regression; analysis was not conducted for Salmonella or STEC because the number of samples positive for these pathogens was low. Although univariate analysis identified associations between isolation of L. monocytogenes or Listeria spp. from terrestrial samples and various water-related factors (e.g., proximity to wetlands and precipitation), multivariate analysis revealed that only irrigation within 3 days of sample collection was significantly associated with isolation of L. monocytogenes (odds ratio = 39) and Listeria spp. (odds ratio = 5) from terrestrial samples. These findings suggest that intervention at the irrigation level may reduce the risk of produce contamination. PMID:26038903

    From May 1989 through April 1990, 1,001 adult homosexual and bisexual men attending urban sexually transmitted disease clinics were interviewed regarding abusive sexual contacts during childhood and adolescence. Sexual abuse was found to be significantly associated with mental health counseling and hospitalization, psychoactive substance use, depression, suicidal thought or actions, social support, sexual identity development, HIV risk behavior including unprotected and intercourse and injecting drug use, and risk of sexually transmitted diseases including HIV infection. Data suggest that sexual abuse may have a wide-ranging influence on the quality of life and health risk behavior of homosexual men. Increased awareness as to the potential outcomes of male sexual abuse is critically important to the design and implementation of medical and psychological services for sexually abused men.

    Dietzia spp. have broad potential applications in industries. However, genetic manipulation of these species is obstructed by their low transformation efficiency, which is in the range of 10(4)colony-forming units (CFU)μg(-1) exogenous DNA. In this study, both single-factor and orthogonal experiments were conducted to test the effects of competent cell concentration (parameter A), electroporation time (B), and field strength (C), as well as the concentrations of glycine (D), isonicotinic acid hydrazide (INH, E), Tween 80 (F), and penicillin G (G) on the electrotransformation efficiency of Dietzia sp. DQ12-45-1b. The order in which the parameters contributed to electrotransformation efficiency was C>D>F>G>B>A>E, suggesting that field strength, glycine, and Tween 80 each had a greater capability to increase electrotransformation efficiency than the other parameters tested. Using the optimized protocol deduced from the results of the orthogonal experiments, the electrotransformation efficiency of Dietzia sp. DQ12-45-1b reached 2.51×10(7)CFUμg(-1) plasmid. To the best of our knowledge, this is the highest transformation efficiency that has been reported for Dietzia bacteria to date. Thus, we present a method that combines the transformation factors to obtain the optimal transformation efficiency for a target bacterium. PMID:24892513

    The aim of this study is to examine associations among childhood physical, emotional, or sexual abuse and violence toward self (suicide attempts [SA]) and others (interpersonal aggression [IA]). Data were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions Waves 1 and 2 (n = 34,653). Multinomial logistic regression examined associations between type of childhood abuse and violence categories, adjusting for demographic variables, other childhood adversity, and DSM-IV psychiatric disorders. The prevalence of reported childhood abuse was 4.60% for physical abuse, 7.83% for emotional abuse, and 10.20% for sexual abuse. Approximately 18% of adults reported some form of violent behavior, distributed as follows: IA, 13.37%; SA, 2.64%; and SA with IA, 1.85%. After adjusting for demographic variables, other childhood adversity, and psychiatric disorders, each type of childhood abuse was significantly related to increased risk for each violence category as compared with the no violence category. Furthermore, the odds ratio of childhood physical abuse was significantly higher for SA with IA when compared with IA, and the odds ratio of childhood sexual abuse was significantly higher for SA and SA with IA when compared with IA. Childhood physical, emotional, and sexual abuse is directly related to the risk for violent behaviors to self and others. Both internalizing and externalizing psychiatric disorders impact the association between childhood abuse and violence. The inclusion of suicidal behaviors and interpersonal aggression and internalizing/externalizing psychiatric disorders within an integrated conceptual framework will facilitate more effective interventions for long-lasting effects of child abuse.

The risk increase among those with substance abuse comorbidity was significantly less pronounced when unaffected siblings were used as controls (28.3% of those with schizophrenia had a violent offense compared with 17.9% of their unaffected siblings; adjusted OR, 1.8; 95% CI, 1.4-2.4; P<.001 for interaction), suggesting significant familial (genetic or early environmental) confounding of the association between schizophrenia and violence. Conclusions Schizophrenia was associated with an increased risk of violent crime in this longitudinal study. This association was attenuated by adjustment for substance abuse, suggesting a mediating effect. The role of risk assessment, management, and treatment in individuals with comorbidity needs further examination. PMID:19454640

    Child abuse and neglect is a public health problem and usually associated with family dysfunction due to multiple psychosocial, individual, and environmental factors. The diagnosis of child abuse may be difficult and require a high index of suspicion on the part of the practitioners encountering the child and the family. System-related factors may also enable abuse or prevent the early recognition of abuse. Child abuse and neglect that goes undiagnosed may give rise to chronic abuse and increased morbidity-mortality. In this report, we present two siblings who missed early diagnosis and we emphasize the importance of systems issues to allow early recognition of child abuse and neglect. PMID:25084799

    Background & Aims Occasional risk of serious liver dysfunction and autoimmune hepatitis during atorvastatin therapy has been reported. We compared the risk of hepatotoxicity in atorvastatin relative to simvastatin treatment. Methods The UK GPRD identified patients with a first prescription for simvastatin [164,407] or atorvastatin [76,411] between 1997 and 2006, but with no prior record of liver disease, alcohol-related diagnosis, or liver dysfunction. Incident liver dysfunction in the following six months was identified by biochemical value and compared between statin groups by Cox regression model adjusting for age, sex, year treatment started, dose, alcohol consumption, smoking, body mass index and comorbid conditions. Results Moderate to severe hepatotoxicity [bilirubin >60μmol/L, AST or ALT >200U/L or alkaline phosphatase >1200U/L] developed in 71 patients on atorvastatin versus 101 on simvastatin. Adjusted hazard ratio [AHR] for all atorvastatin relative to simvastatin was 1.9 [95% confidence interval 1.4–2.6]. High dose was classified as 40–80mg daily and low dose 10–20mg daily. Hepatotoxicity occurred in 0.44% of 4075 patients on high dose atorvastatin [HDA], 0.07% of 72,336 on low dose atorvastatin [LDA], 0.09% of 44,675 on high dose simvastatin [HDS] and 0.05% of 119,732 on low dose simvastatin [LDS]. AHRs compared to LDS were 7.3 [4.2–12.7] for HDA, 1.4 [0.9–2.0] for LDA and 1.5 [1.0–2.2] for HDS. Conclusions The risk of hepatotoxicity was increased in the first six months of atorvastatin compared to simvastatin treatment, with the greatest difference between high dose atorvastatin and low dose simvastatin. The numbers of events in the analyses were small. PMID:26983033

    subjects. Results: For 0.4 T pulses at 2, 25, 59, 101, and 183 kHz, stimulation was reported by 22 (84.6%), 24 (92.3%), 15 (57.7%), 2 (7.7%), and 1 (3.8%) subjects, respectively. Conclusions: The probability of PNS due to brief biphasic time-varying sinusoidal magnetic fields with magnetic excursions up to 0.4 T is shown to decrease significantly at and above 101 kHz. This phenomenon may have particular uses in dynamic scenarios (e.g., cardiac imaging) and in studying processes with short decay times (e.g., electron paramagnetic resonance imaging, bone and solids imaging). The study suggests the possibility of new designs for human and preclinical MRI systems that may be useful in clinical practice and scientific research. PMID:22559628

    This study compared abusive husbands with nonabusive, marital discordant husbands using six measures to ascertain certain etiological characteristics of abusers. Both groups completed the Jenkins Activity Survey for measuring type A behavior, the Short Michigan Alcoholism Screening Test, the Index of Self-Esteem, the Spence-Helmrich Attitudes Toward Women Scale, the Index of Marital Satisfaction, and a simple rating scale to access their perceptions of their wives' physical attractiveness. As predicted, abusers evidence significantly higher type A behaviors, higher problem drinking behaviors, more rigid attitudes toward women, lower marital satisfaction, and rated their wives as less attractive than did nonabusers. Inconsistent with the literature, however, no significant differences were discovered between the self-esteem of abusers and nonabusers. PMID:1780068

    Thirty-nine children were reviewed who had suffered child abuse at an average of 5 1/2 years earlier. In comparison with a group matched for socio-economic status, the abused children performed significantly lower on the Wechsler Intelligence Scale, and were more delayed in language development and reading ability. Their teachers' assessments of behaviour showed significantly more abnormal profiles than in the comparison group. These differences could not be accounted for by the small proportion of known head-injuries in the abused group. Child abuse has long-term effects, so it is necessary that these children are thoroughly assessed at first presentation, and that they are followed with a specific programme aimed at preventing these sequelae.

    1984-01-01

    Although child abuse occurs in Nigeria, it has received little attention. This is probably due to the emphasis placed on the more prevalent childhood problems of malnutrition and infection. Another possible reason is the general assumption that in every African society the extended family system always provides love, care and protection to all children. Yet there are traditional child rearing practices which adversely affect some children, such as purposeful neglect or abandonment of severely handicapped children, and twins or triplets in some rural areas. With the alteration of society by rapid socioeconomic and political changes, various forms of child abuse have been identified, particularly in the urban areas. These may be considered the outcome of abnormal interactions of the child, parents/ guardians and society. They include abandonment of normal infants by unmarried or very poor mothers in cities, increased child labour and exploitation of children from rural areas in urban elite families, and abuse of children in urban nuclear families by childminders . Preventive measures include provision of infrastructural facilities and employment opportunities in the rural areas in order to prevent drift of the young population to the cities. This would sustain the supportive role of the extended family system which is rapidly being eroded. There is need for more effective legal protection for the handicapped child, and greater awareness of the existence of child abuse in the community by health and social workers. PMID:6232976

    2015-02-01

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. PMID:25471045

    Among the social and medical ills of the twentieth century, substance abuse ranks as on one of the most devastating and costly. The drug problem today is a major global concern including Bangladesh. Almost all addictive drugs over stimulate the reward system of the brain, flooding it with the neurotransmitter dopamine. That produces euphoria and that heightened pleasure can be so compelling that the brain wants that feeling back again and again. However repetitive exposure induces widespread adaptive changes in the brain. As a consequence drug use may become compulsive. An estimated 4.7% of the global population aged 15 to 64 or 184 million people, consume illicit drug annually. Heroin use alone is responsible for the epidemic number of new cases of HIV/AIDS, Hepatitis and drug addicted infant born each year. Department of narcotic control (DNC) in Bangladesh reported in June 2008 that about 5 million drug addicts in the country & addicts spend at least 17 (Seventeen) billion on drugs per year. Among these drug addicts, 91% are young and adolescents population. Heroin is the most widely abused drugs in Bangladesh. For geographical reason like India, Pakistan and Myanmar; Bangladesh is also an important transit root for internationally trafficking of illicit drug. Drug abuse is responsible for decreased job productivity and attendance increased health care costs, and escalations of domestic violence and violent crimes. Drug addiction is a preventable disease. Through scientific advances we now know much more about how exactly drugs work in the brain, and we also know that drug addiction can be successfully treated to help people stop abusing drugs and resume their productive lives. Most countries have legislation designed to criminalize some drugs. To decrease the prevalence of this problem in our setting; increase awareness, promoting additional research on abused and addictive drugs, and exact implementation of existing laws are strongly recommended.

    This study examined whether child abuse history in teen mothers impacts offspring externalizing problems indirectly, through its influence on attachment and maternal hostility. In a longitudinal sample of 112 teen mother-child dyads, mothers reported on their own abuse experiences, attachment and maternal hostility were assessed via direct observations, and externalizing problems were measured using maternal reports. Compared with mothers with no abuse history, mothers with a history of sexual and physical abuse were more likely to have an insecurely attached infant, which predicted higher externalizing problems in preschool, which in turn predicted subsequent increases in externalizing problems in Grade 3. Furthermore, relative to the no abuse history group, mothers with a history of sexual and physical abuse showed more hostility toward their child at preschool, which in turn predicted elevated externalizing problems in Grade 3. Mothers' history of either sexual or physical abuse alone did not have significant indirect effects on externalizing problems. Fostering secure attachment and reducing risk for maternal hostility might be important intervention goals for prevention programs involving at-risk mothers with abuse histories. PMID:27174770

    ABSTRACT OBJECTIVE To examine harassment and abusive encounters between family physicians and their patients or colleagues in the workplace. DESIGN Qualitative case study using semistructured interviews. SETTING Province of New Brunswick. PARTICIPANTS Forty-eight family physicians from across the province. METHODS A collective case-study approach was developed, with 24 cases of 2 individuals per case. Cases were selected based on sex, location (urban or rural), language (French or English), and number of years since medical school graduation (< 10 years, 10 to 20 years, or > 20 years). Physicians were interviewed in either French or English. Participants were recruited using the College of Physicians and Surgeons of New Brunswick’s physician directory. Based on the rates of response and participation, some cases were overrepresented, while others were not completed. All interviews were audiotaped, transcribed verbatim, and analyzed thematically using a categorical aggregation approach. A coding scheme for the thematic analysis was developed by the research team before the interviews were transcribed. MAIN FINDINGS Although the original intent of this study was to examine the work environment of family physicians in light of the increasing number of women entering the profession, harassment and abusive encounters in the workplace emerged as a main theme. These encounters ranged from minor to severe. Minor abusive encounters included disrespectful behaviour and verbal threats by patients, their families, and occasionally colleagues. More severe forms of harassment involved physical threats, physical encounters, and stalking. Demanding patients, such as heavy drug users, were often seen as threatening. Location of practice, years in practice, and sex of the physician seemed to affect abusive encounters—young, female, rural physicians appeared to experience such encounters most often. CONCLUSION Abusive encounters in the workplace are concerning. It is essential to

    As lithium-ion battery technologies mature, the size and energy of these systems continues to increase (> 50 kWh for EVs); making safety and reliability of these high energy systems increasingly important. While most material advances for lithium-ion chemistries are directed toward improving cell performance (capacity, energy, cycle life, etc.), there are a variety of materials advancements that can be made to improve lithium-ion battery safety. Issues including energetic thermal runaway, electrolyte decomposition and flammability, anode SEI stability, and cell-level abuse tolerance continue to be critical safety concerns. This report highlights work with our collaborators to develop advanced materials to improve lithium-ion battery safety and abuse tolerance and to perform cell-level characterization of new materials.

    Moves to legalize marijuana highlight the urgency to investigate effects of chronic marijuana in the human brain. Here, we challenged 48 participants (24 controls and 24 marijuana abusers) with methylphenidate (MP), a drug that elevates extracellular dopamine (DA) as a surrogate for probing the reactivity of the brain to DA stimulation. We compared the subjective, cardiovascular, and brain DA responses (measured with PET and [(11)C]raclopride) to MP between controls and marijuana abusers. Although baseline (placebo) measures of striatal DA D2 receptor availability did not differ between groups, the marijuana abusers showed markedly blunted responses when challenged with MP. Specifically, compared with controls, marijuana abusers had significantly attenuated behavioral ("self-reports" for high, drug effects, anxiety, and restlessness), cardiovascular (pulse rate and diastolic blood pressure), and brain DA [reduced decreases in distribution volumes (DVs) of [(11)C]raclopride, although normal reductions in striatal nondisplaceable binding potential (BPND)] responses to MP. In ventral striatum (key brain reward region), MP-induced reductions in DVs and BPND (reflecting DA increases) were inversely correlated with scores of negative emotionality, which were significantly higher for marijuana abusers than controls. In marijuana abusers, DA responses in ventral striatum were also inversely correlated with addiction severity and craving. The attenuated responses to MP, including reduced decreases in striatal DVs, are consistent with decreased brain reactivity to the DA stimulation in marijuana abusers that might contribute to their negative emotionality (increased stress reactivity and irritability) and addictive behaviors.

    Childhood maltreatment has been implicated as a risk factor for adult obesity. We describe the first prospective assessment of adult obesity in individuals with documented histories of childhood physical and sexual abuse and neglect and a matched comparison group in a 30-year follow-up. Using a prospective cohort design, children with court substantiated cases of physical and sexual abuse and neglect (ages 0-11 years) from a Midwest county during 1967-1971 (n=410) were matched with children without histories of abuse or neglect on age, sex, race/ethnicity and approximate family social class (n=303) and followed up and assessed at mean age 41. Outcome measures include BMI and obesity assessed in 2003-2004 as part of a medical status examination and interview. Childhood physical abuse predicted significantly higher BMI scores in adulthood (beta=0.14, P<0.05), even controlling for demographic characteristics, cigarette smoking, and alcohol consumption (beta=0.16, P<0.01). Childhood sexual abuse (beta=0.07, not significant) and neglect (beta=0.02, not significant) were not significant predictors of adult BMI scores. These results demonstrate the long-term impact of childhood physical abuse on weight into adulthood and suggest that physically abused children may be at risk for other adverse health outcomes associated with increased weight. Health professionals need to understand this risk for physically abused children and researchers should identify and evaluate strategies for effective interventions. PMID:19478789

  20. Postmortem toxicology of drugs of abuse.

    Conducting toxicology on post-mortem specimens provides a number of very significant challenges to the scientist. The range of additional specimens include tissues such as decomposing blood and other tissues, hair, muscle, fat, lung, and even larvae feeding on the host require special techniques to isolate a foreign substance and allow detection without interference from the matrix. A number of drugs of abuse are unstable in the post-mortem environment that requires careful consideration when trying to interpret their significance. Heroin, morphine glucuronides, cocaine and the benzodiazepines are particularly prone to degradation. Moreover, redistributive process can significantly alter the concentration of drugs, particularly those with a higher tissue concentration than the surrounding blood. The designer amphetamines, methadone and other potent opioids will increase their concentration in blood post-mortem. These processes together with the development of tolerance means that no concentration of a drug of abuse can be interpreted in isolation without a thorough examination of the relevant circumstances and after the conduct of a post-mortem to eliminate or corroborate relevant factors that could impact on the drug concentration and the possible effect of a substance on the body. This article reviews particular toxicological issues associated with the more common drugs of abuse such as the amphetamines, cannabinoids, cocaine, opioids and the benzodiazepines. PMID:15172074

    Staff turnover is a significant issue within substance abuse treatment, with implications for service delivery and organizational health. This study examined factors associated with turnover among supervisors in outpatient substance abuse treatment. Turnover was conceptualized as being an individual response to organizational-level influences, and predictors represent aggregate program measures. Participants included 532 staff (including 467 counselors and 65 clinical/program directors) from 90 programs in four regions of the USA. Using logistic regression, analyses of structural factors indicated that programs affiliated with a parent organization and those providing more counseling hours to clients had higher turnover rates. When measures of job attitudes were included, only parent affiliation and collective appraisal of satisfaction were related to turnover. Subsequent analyses identified a trend toward increased supervisory turnover when satisfaction was low following the departure of a previous supervisor. These findings suggest that organizational-level factors can be influential in supervisory turnover. PMID:19949883

    To date, no studies have investigated emotional abuse of adult Latina women by their mothers despite evidence that emotional maternal abuse may significantly contribute to the emotional abuse experienced by Latina women in their lifetime. Cross-sectional data including 316 women was analyzed using mediation and logistic regression. Overall, 7.1 % of mothers and 24.1 % of daughters abused drugs; and, 19.5 % of daughters were emotionally abused by their mothers. Mother's attachment to her daughter mediated the association between mother's drug abuse and emotionally abusing her adult daughter (indirect effect: 0.863). Latina women can serve as perpetrators of emotional abuse of their adult children. Since drug-abusing daughters are more likely to be victims of emotional abuse by their mothers and drug-abusing mothers are more likely to abuse their daughters, drug-rehabilitation practitioners should incorporate a family abuse component into rehabilitation programs.

    Although the link between substance abuse and child maltreatment has been relatively well established, there is a general recognition that this is not a simple cause-effect relationship. The current study explored the relationships among substance abuse, family functioning, and abuse/neglect in a sample of incarcerated substance abusers. Data were gathered on the earlier life experiences of 81 men and women serving sentences in two maximum security prisons, including assessments of their parents' substance abuse problems; levels of family competence within their families-of-origin; their exposure, as children and adults, to physical, emotional, and sexual abuse and physical/emotional neglect; and their own levels of substance abuse. Results showed generally high percentages of parental substance abuse and abuse/neglect, and relatively low levels of family competence. Correlational analyses revealed significant direct and indirect relationships among parental substance abuse, family dynamics, and exposure to both child and adult maltreatment. These four variables were also significantly associated with respondents' own substance abuse in later life, suggesting the potential for continuation of these patterns into successive generations. An intergenerational model of these family and personal functioning variables is presented and implications for service delivery with correctional clients is discussed. PMID:7664133

    Developmental theories highlight the salience of attachment theory in explaining vulnerability towards psychosis. At the same time there is increasing recognition that psychosis is associated with childhood trauma variables. This study explored the interaction between attachment and several trauma variables in relation to schizotypy levels in a non-clinical sample. 283 non-clinical participants completed online measures of schizotypy, attachment, childhood abuse and neglect. When five types of abuse/neglect were entered into a linear regression analysis emotional abuse was the sole independent predictor of schizotypy. Age, attachment anxiety and avoidance were independent predictors after the effects of emotional abuse were controlled for. The overall model was significant, explaining 34% of the variation in schizotypy. Moderation analysis indicated that the effect of emotional abuse was not conditional upon attachment. Parallel mediation analysis indicated small but significant indirect effects of emotional abuse on schizotypy through attachment avoidance (13%) and attachment anxiety (8%). We conclude that emotional abuse contributes to vulnerability towards psychosis both directly and indirectly through attachment insecurity. PMID:26474661

    Dementia and elder abuse are relatively common and under-diagnosed geriatric syndromes. A unique relationship is observed when the two entities coexist. Special issues can confound the care of the dementia patient suspected of being abused. Impaired language or motor abilities to communicate abusive situations to a third party, lack of decisional capacity to address the abusive situation, disinhibited behavior that contributes to a cycle of violence, and coincident depression of the abused elder complicate the diagnosis and management of elder abuse. Education of the caregiver and attention to caregiver stress, including depression, may prevent onset and perpetuation of abuse. PMID:15804553

    This study examined self-reported sexually abusive experiences in childhood and adulthood as correlates of current drug use, alcohol abuse, and depression and posttraumatic stress disorder (PTSD) symptoms. Participants were 204 Latina women 18–34 years old. Results indicated significant relationships between history of sexual abuse (regardless of age of occurrence), depression symptoms, PTSD symptoms, alcohol abuse, and drug use. When examined separately, childhood sexual abuse was associated with symptoms of depression, PTSD, and substance use but not alcohol abuse behaviors. Experiencing sexual abuse in adulthood was associated with symptoms of depression, alcohol abuse behaviors, and substance use but not PTSD symptoms. Structural equation modeling showed that substance use partially mediated the relationship between sexual abuse and mental health outcomes. These findings suggest mental health and substance use services should incorporate treatment for trauma, which may be the root of comorbid mental health and substance use issues. PMID:25635897

    The abuse of alkyl nitrites is common among adolescents and young adults worldwide. However, the information regarding the effects of alkyl nitrites on the central nervous system and the associated psychological abuse potential is scarce. The abuse potential of 3 representative alkyl nitrites - isobutyl nitrite, isoamyl nitrite, and butyl nitrite - was evaluated in mice using conditioned place preference tests with an unbiased method. The dopamine levels released by synaptosomes extracted from the striatal region were measured using high performance liquid chromatography. Mice treated with the test substances (50mg/kg, i.p.) exhibited a significantly increased drug-paired place preference. Moreover, greater levels of dopamine were released by striatal region synaptosomes in response to isobutyl nitrite treatment in mice. Thus, our findings suggest that alkyl nitrites could lead to psychological dependence and dopaminergic effects. Furthermore, these results provide scientific evidence to support the regulation of alkyl nitrites as psychoactive substances in the future. PMID:27369324

    The objective of this study was to determine if physical and sexual abuse showed relationships to early-onset bipolar spectrum disorders (BPSD) consistent with findings from adult retrospective data. Participants (N=829, M= 10.9 years old ±3.4 SD, 60 % male, 69 % African American, and 18 % with BPSD), primarily from a low socio-economic status, presented to an urban community mental health center and a university research center. Physical abuse was reported in 21 %, sexual abuse in 20 %, and both physical and sexual abuse in 11 % of youths with BPSD. For youths without BPSD, physical abuse was reported in 16 %, sexual abuse in 15 %, and both physical and sexual abuse in 5 % of youths. Among youth with BPSD, physical abuse was significantly associated with a worse global family environment, more severe depressive and manic symptoms, a greater number of sub-threshold manic/hypomanic symptoms, a greater likelihood of suicidality, a greater likelihood of being diagnosed with PTSD, and more self-reports of alcohol or drug use. Among youth with BPSD, sexual abuse was significantly associated with a worse global family environment, more severe manic symptoms, a greater number of sub-threshold manic/hypomanic symptoms, greater mood swings, more frequent episodes, more reports of past hospitalizations, and a greater number of current and past comorbid Axis I diagnoses. These findings suggest that if physical and/or sexual abuse is reported, clinicians should note that abuse appears to be related to increased severity of symptoms, substance use, greater co-morbidity, suicidality, and a worse family environment.

    There is increasing interest in childhood maltreatment as a potent stimulus that may alter trajectories of brain development, induce epigenetic modifications and enhance risk for medical and psychiatric disorders. Although a number of useful scales exist for retrospective assessment of abuse and neglect they have significant limitations. Moreover, they fail to provide detailed information on timing of exposure, which is critical for delineation of sensitive periods. The Maltreatment and Abuse Chronology of Exposure (MACE) scale was developed in a sample of 1051 participants using item response theory to gauge severity of exposure to ten types of maltreatment (emotional neglect, non-verbal emotional abuse, parental physical maltreatment, parental verbal abuse, peer emotional abuse, peer physical bullying, physical neglect, sexual abuse, witnessing interparental violence and witnessing violence to siblings) during each year of childhood. Items included in the subscales had acceptable psychometric properties based on infit and outfit mean square statistics, and each subscale passed Andersen's Likelihood ratio test. The MACE provides an overall severity score and multiplicity score (number of types of maltreatment experienced) with excellent test-retest reliability. Each type of maltreatment showed good reliability as did severity of exposure across each year of childhood. MACE Severity correlated 0.738 with Childhood Trauma Questionnaire (CTQ) score and MACE Multiplicity correlated 0.698 with the Adverse Childhood Experiences scale (ACE). However, MACE accounted for 2.00- and 2.07-fold more of the variance, on average, in psychiatric symptom ratings than CTQ or ACE, respectively, based on variance decomposition. Different types of maltreatment had distinct and often unique developmental patterns. The 52-item MACE, a simpler Maltreatment Abuse and Exposure Scale (MAES) that only assesses overall exposure and the original test instrument (MACE-X) with several additional

    Using a randomly selected community-based sample, this investigation examined whether histories of childhood sexual, physical, and death threat abuse predicted adulthood outcomes of specific medical and psychiatric conditions involving chronic fatigue. This study also tested prior suggestions that most individuals with chronic fatigue syndrome report a past history of interpersonal abuse. Multinomial logistic regression was used to examine the relationship between abuse history and chronic fatigue group outcomes while controlling for the effects of sociodemographics. Compared with healthy controls, childhood sexual abuse was significantly more likely to be associated with outcomes of idiopathic chronic fatigue, chronic fatigue explained by a psychiatric condition, and chronic fatigue explained by a medical condition. None of the abuse history types were significant predictors of chronic fatigue syndrome. A closer examination of individuals in the chronic fatigue syndrome group revealed that significantly fewer individuals with CFS reported abuse as compared with those who did not. The implications of these findings are discussed. PMID:11708672

    Backgrounds: Drug abuse is one of the most serious social problems in many countries. College students, particularly at their first year of education, are considered as one of the at risk groups for drug abuse. The present study aimed to determine cognitive factors related to drug abuse among a sample of Iranian male medical college students based on the social cognitive theory (SCT). Method: This cross-sectional study was carried out on 425 Iranian male medical college students who were randomly selected to participate voluntarily in the study. The participants filled out a self-administered questionnaire. Data were analyzed by the SPSS software (ver. 21.0) using bivariate correlations, logistic and linear regression at 95% significant level. Results: Attitude, outcome expectation, outcome expectancies, subjective norms, and self-control were cognitive factors that accounted for 49% of the variation in the outcome measure of the intention to abuse drugs. Logistic regression showed that attitude (OR=1.062), outcome expectancies (OR=1.115), and subjective norms (OR=1.269) were the most influential predictors for drug abuse. Conclusions: The findings suggest that designing and implementation of educational programs may be useful to increase negative attitude, outcome expectancies, and subjective norms towards drug abuse for college students in order to prevent drug abuse.

    There is increasing interest from a social learning perspective in understanding the role of parental factors on adult health behaviors and health outcomes. Our review revealed no studies, to date, that have evaluated the effects of parental substance abuse on reports of chronic pain and coping in adult patients with sickle cell disease (SCD). We explored the effects of parental substance (alcohol or drug) abuse on reports of the sensory, affective and summary indices of pain in 67 adult patients, mean age 38.9 (13.5), with SCD. We also explored the effects of parental substance abuse on psychopathology associated with pain and active coping. Twenty-four percent of patients reported that their parent(s) abused substances. Patients whose parent(s) were characterized as substance abusers reported greater sensory (p=0.02), affective (p=0.01) and summary (VAS; p=0.02) indices of pain as compared to their counterparts, whose parent(s) were not characterized as substance abusers. Patients did not differ in average age, education or the propensity to respond in a socially acceptable manner. There was a significant trend towards patients who characterized their parents as abusers scoring higher than their counterparts on active coping. We propose a Social Learning Theory to explain the current findings and suggest a need for additional prospective research to simultaneously explore biological (genetic) and social factors that influence the interpretation, experience and reporting of chronic pain in adult patients with chronic disease.

    OBJECTIVE To assess the prevalence of medical student abuse during clinical clerkships in Japan. DESIGN A cross-sectional questionnaire survey. SETTING Six medical schools in Japan. PARTICIPANTS Final year (sixth-year) and fifth-year medical students in the period from September 2003 to January 2004. From a total of 559 students solicited, 304 (54.4%) returned the questionnaire, and 276 (49.4%: 178 male and 98 female) completed it. MEASUREMENTS Prevalence of medical student abuse in 5 categories: verbal abuse, physical abuse, academic abuse, sexual harassment, and gender discrimination; differences in abusive experience between male and female students; types of alleged abusers; reporting abusive experiences to authorities; and emotional effects of abusive experiences. RESULTS Medical student abuse was reported by 68.5% of the respondents. Verbal abuse was the most frequently experienced abuse (male students 52.8%, female students 63.3%). Sexual harassment was experienced significantly more often (P<.001) by female students (54.1%) than by male students (14.6%). Faculty members were most often reported as abusers (45.2% of cases). Abuse occurred most frequently during surgical rotations (42.0% of cases), followed by internal medicine (25.1%) and anesthesia rotations (21.8%). Very few abused students reported their abusive experiences to authorities (8.5%). The most frequent emotional response to abuse was anger (27.1% of cases). CONCLUSIONS Although experience of abuse during clinical clerkships is common among medical students in Japan, the concept of “medical student abuse” is not yet familiar to Japanese. To improve the learning environment, medical educators need to take action to resolve this serious issue. PMID:16390504

    Objective To assess the relationship between cumulative environmental risks and early intervention, parenting attitudes, potential for child abuse and child development in substance abusing mothers. Method We studied 161 substance-abusing women, from a randomized longitudinal study of a home based early intervention, who had custody of their children through 18 months. The intervention group received weekly home visits in the first 6 months and biweekly visits from 6 to 18 months. Parenting stress and child abuse potential were assessed at 6 and 18 months postpartum. Children’s mental and motor development (Bayley MDI and PDI) and language development (REEL) were assessed at 6, 12, and 18 months postpartum. Ten maternal risk factors were assessed: maternal depression, domestic violence, nondomestic violence, family size, incarceration, no significant other in home, negative life events, psychiatric problems, homelessness, and severity of drug use. Level of risk was recoded into four categories (2 or less, 3, 4, and 5 or more), which had adequate cell sizes for repeated measures analysis. Data analysis Repeated measures analyses were run to examine how level of risk and group (intervention or control) were related to parenting stress, child abuse potential, and children’s mental, motor and language development over time. Results Parenting stress and child abuse potential were higher for women with five risks or more compared with women who had four or fewer risks; children’s mental, motor, and language development were not related to level of risk. Children in the intervention group had significantly higher scores on the PDI at 6 and 18 months (107.4 vs. 103.6 and 101.1 vs. 97.2) and had marginally better scores on the MDI at 6 and 12 months (107.7 vs. 104.2 and 103.6 vs. 100.1), compared to the control group. Conclusion Compared to drug-abusing women with fewer than five risks, women with five or more risks found parenting more stressful and indicated greater

  4. Review: The neuropathology of drug abuse.

    2011-02-01

    Drug abuse represents a significant health issue. The major substances abused include cannabis, opiates, cocaine, amphetamine, methamphetamine and 'ecstasy'. Alterations of intracellular messenger pathways, transcription factors and immediate early genes within the brain reward system seem to be fundamentally important for the development of addiction and chronic drug abuse. Genetic risk factors and changes in gene expression associated with drug abuse are still poorly understood. Besides cardiovascular complications, psychiatric and neurologic symptoms are the most common manifestations of drug toxicity. A broad spectrum of changes affecting the central nervous system is seen in drug abusers. The major findings result from the consequences of ischaemia and cerebrovascular diseases. Except for a few observations of vasculitis, the aetiology of these cerebrovascular accidents is not fully understood. The abuse of amphetamine, methamphetamine and MDMA has been related to neurotoxicity in human long-term abusers and to the risk of developing Parkinson's disease. However, whether such neurotoxicity occurs remain to be established. Systematic histological, immunohistochemical and morphometric investigations have shown profound morphological alterations in the brains of polydrug abusers. The major findings comprise neuronal loss, neurodegenerative alterations, a reduction of glial fibrillary acidic protein-immunopositive astrocytes, widespread axonal damage with concomitant microglial activation as well as reactive and degenerative changes of the cerebral microvasculature. These observations demonstrate that drugs of abuse initiate a cascade of interacting toxic, vascular and hypoxic factors, which finally result in widespread disturbances within the complex network of central nervous system cell-to-cell interactions.

    Media attention on the misuse of propofol increased significantly when the drug was implicated in the death of pop music superstar Michael Jackson in 2010. The misuse and abuse of propofol among healthcare providers has been reported worldwide, with some misuse resulting in death. Propofol policies guiding healthcare worker re-entry into the workplace after misusing propofol have received rare attention in the research literature. The paucity of information regarding propofol-specific re-entry policies suggests that little research has addressed this problem and the lack of research and policy guidance can contribute to unsafe re-entry and even death. This paper focuses on healthcare providers because they have an easy access to propofol and therefore are vulnerable to misusing or abusing the drug. To accomplish this, the pharmacology and misuse/abuse potential of propofol and the influence of the 12-step recovery paradigm in the re-entry literature are reviewed. In conclusion, existing research and policy are drawn upon to suggest employment re-entry guidelines for healthcare workers. PMID:21463203

    Background: Nationally representative Canadian data on the prevalence of child abuse and its relation with mental disorders are lacking. We used contemporary, nationally representative data to examine the prevalence of 3 types of child abuse (physical abuse, sexual abuse and exposure to intimate partner violence) and their association with 14 mental conditions, including suicidal ideation and suicide attempts. Methods: We obtained data from the 2012 Canadian Community Health Survey: Mental Health, collected from the 10 provinces. Respondents aged 18 years and older were asked about child abuse and were selected for the study sample (n = 23 395). The survey had a multistage stratified cluster design (household response rate 79.8%). Results: The prevalence of any child abuse was 32% (individual types ranged from 8% to 26%). All types of child abuse were associated with all mental conditions, including suicidal ideation and suicide attempts, after adjustment for sociodemographic variables (adjusted odds ratios ranged from 1.4 to 7.9). We found a dose–response relation, with increasing number of abuse types experienced corresponding with greater odds of mental conditions. Associations between child abuse and attention deficit disorder, suicidal ideation and suicide attempts showed stronger effects for women than men. Interpretation: We found robust associations between child abuse and mental conditions. Health care providers, especially those assessing patients with mental health problems, need to be aware of the relation between specific types of child abuse and certain mental conditions. Success in preventing child abuse could lead to reductions in the prevalence of mental disorders, suicidal ideation and suicide attempts. PMID:24756625

    Background Childhood abuse has been associated with significant increases in non-suicidal self-injury (NSSI) behaviors in adolescents; however, only general definitions of this risk indicator have been examined. This study identified relationships between specific forms of childhood abuse and NSSI in mainland Chinese adolescents. Method A total of 14,221 cases were retained from an epidemiological study involving adolescents from junior and senior middle schools. Information relating to the perpetrator, perceived harm, timing of exposure to different types of childhood abuse, and NSSI were obtained. Logistic regression was used to analyze relationships between each form of childhood abuse and NSSI. Results Approximately 51.0% of the students reported at least one abusive childhood experience. Nearly one in four students (24.9%) reported that they had engaged in NSSI in the past 12 months. Each type of childhood abuse, occurring at any time within the first 16 years of life, especially in situations of continuous exposure, was significantly associated with NSSI. A significant graded relationship was found between number of abusive childhood experiences and NSSI. Students maltreated by parents or others were at high risk of engaging in NSSI, the risk was greater in students maltreated by both; students who had been exposed to childhood abuse with no perceived harm still demonstrated an elevated risk for NSSI. The pattern of associations did not vary by gender. Conclusions These findings suggest that experiencing any of various forms of childhood abuse should be considered a risk factor for NSSI during adolescence. Further research should focus upon psychosocial, neural, and genetic factors that might moderate or mediate the onset of NSSI in adolescents who have experienced childhood abuse. PMID:26114574

    The infiltration of 'primed' polymorphonuclear neutrophils into multiple organs has been reported in cases of traumatic or hemorrhagic shock. Since multiple injuries are usually observed in cases of physical abuse of the elderly, we investigated neutrophil infiltration into the heart, lung, liver and kidney in cases of abused elderly individuals using immunohistochemistry for myeloperoxidase (MPO). In addition, we examined the expression of molecules associated with neutrophil infiltration, including P-selectin as the adhesion molecule and IL-8 as the chemotactic factor. The number of neutrophils in the physically abused elder cases was increased significantly, particularly in the lung and liver, compared with that of control cases of sharp instrument injury, single fatal blunt injury and polytrauma. In addition, P-selection expression in the endothelium and the presence of IL-8-positive cells (mainly macrophages) in the lung and liver of abuse cases were significantly greater than those in control cases. In contrast, the number of MPO-, P-selectin- and IL-8-positive cells in cases of multiple organ failure (MOF) due to various causes was significantly greater than that in abuse cases. It is known that primed neutrophils accumulation may undergo MOF by 'activation' due to secondary insults. Thus, our results suggest that MPO immunostaining can distinguish cases of elderly physical abuse from non-abuse and MOF cases. In addition, our results indicate that MPO is a potential diagnostic marker for elder physical abuse, and that P-selectin and IL-8 may be useful for a more accurate diagnosis. Finally, our results also suggest that elder cases of physical abuse may be in a primed stage of MOF, and are at risk of falling into MOF by various secondary insults including those following abuse.

    The study was conducted to investigate the platelet increasing property of Carica papaya leaves juice (CPLJ) in patients with dengue fever (DF). An open labeled randomized controlled trial was carried out on 228 patients with DF and dengue haemorrhagic fever (DHF). Approximately half the patients received the juice, for 3 consecutive days while the others remained as controls and received the standard management. Their full blood count was monitored 8 hours for 48 hours. Gene expression studies were conducted on the ALOX 12 and PTAFR genes. The mean increase in platelet counts were compared in both groups using repeated measure ANCOVA. There was a significant increase in mean platelet count observed in the intervention group (P < 0.001) but not in the control group 40 hours since the first dose of CPLJ. Comparison of mean platelet count between intervention and control group showed that mean platelet count in intervention group was significantly higher than control group after 40 and 48 hours of admission (P < 0.01). The ALOX 12 (FC  =  15.00) and PTAFR (FC  =  13.42) genes were highly expressed among those on the juice. It was concluded that CPLJ does significantly increase the platelet count in patients with DF and DHF. PMID:23662145

    Of 260 children considered to have been the victims of child abuse or neglect, or both, 149 suffered non-accidental injury, 71 had evidence of growth problems, 87 had developmental and speech delay, and 63 showed evidence of appreciable behaviour disturbance. While the overall prevalence of development and behaviour problems in the series was high there were particular associations noted between growth problems and developmental delay, between increasing age and behaviour disturbance, and between evidence of emotional deprivation and both behaviour disturbance and developmental delay. Children with non-accidental injury but without growth problems or emotional deprivation were least likely to show behaviour or developmental problems. PMID:2460032

  16. "Shadows of the heart": a dramatic video for the treatment resistance of spouse abusers.

    PubMed

    1994-11-01

    Successful intervention with spouse abusers, most of whom are ordered into treatment by the courts, must overcome formidable anger and resistance, often expressed by high attrition and scant participation in the group treatment process. The dramatic video "Shadows of the Heart" dissipates client resistance by providing internal motivation to control violent behavior. The video dramatizes spouse abuse from the viewpoint of a young boy, who as a man has become a spouse abuser. As clients experience compassion for the child witness to family violence, they learn to convert their habitual anger response into nonviolent actions. Developed to combat treatment resistance, the video presentation was tested in a randomized experiment with 106 male spouse abusers drawn from seven public and private agencies. Results indicate that the video presentation significantly increased attendance and participation in the group treatment process. PMID:7992138

    2012-07-01

    This NREL Hydrogen and Fuel Cell Technical Highlight describes how hydrogen photoproduction activity in algal cultures can be improved dramatically by increasing the gas-phase to liquid-phase volume ratio of the photobioreactor. NREL, in partnership with subcontractors from the Institute of Basic Biological Problems in Pushchino, Russia, demonstrated that the hydrogen photoproduction rate in algal cultures always decreases exponentially with increasing hydrogen partial pressure above the culture. The inhibitory effect of high hydrogen concentrations in the photobioreactor gas phase on hydrogen photoproduction by algae is significant and comparable to the effect observed with some anaerobic bacteria.

    The sexually abused-sexual abuser hypothesis posits that persons, especially males, who are sexually abused as children are at particular risk of sexually abusing others later in life. We tested this hypothesis by prospectively examining associations between maltreatment and offending in a birth cohort of 38,282 males with a maltreatment history and/or at least one finalized offense. We examined these associations within the context of the wider birth population. Proportionally few boys were the subject of official notifications for sexual abuse (14.8% of maltreated boys, and 1.4% of the birth population); proportionally very few of these sexually abused boys (3%) went on to become sexual offenders; and, contrary to findings typically reported in retrospective clinical studies, proportionally few sexual offenders (4%) had a confirmed history of sexual abuse. Poly-victimization (exposure to multiple types of maltreatment) was significantly associated with sexual offending, violent offending, and general (nonsexual, nonviolent) offending. We found no specific association between sexual abuse and sexual offending, and nor did we find any association between sexual abuse and sexual offending specifically within the poly-victimized group. The total number of sexual abuse notifications did make a small unique contribution to the variance in sexual offending compared to other offending. Implications concerning maltreated boys and male sexual offenders are discussed. PMID:26615777

  20. Preventing abusive head trauma resulting from a failure of normal interaction between infants and their caregivers.

    Barr, Ronald G

    2012-10-16

    Head trauma from abuse, including shaken baby syndrome, is a devastating and potentially lethal form of infant physical abuse first recognized in the early 1970s. What has been less recognized is the role of the early increase in crying in otherwise normal infants in the first few months of life as a trigger for the abuse. In part, this is because infant crying, especially prolonged unsoothable crying, has been interpreted clinically as something wrong with the infant, the infant's caregiver, or the interactions between them. Here, we review an alternative developmental interpretation, namely, that the early increase in crying is a typical behavioral development in normal infants and usually does not reflect anything wrong or abnormal. We also review evidence indicating that this normal crying pattern is the most common trigger for abusive head trauma (AHT). Together, these findings point to a conceptualization of AHT as the consequence of a failure in an otherwise common, iterative, and developmentally normal infant-caregiver interaction. They also imply that there is a window of opportunity for prevention of AHT, and potentially other forms of infant abuse, through a public health primary universal prevention strategy aimed at changing knowledge and behaviors of caregivers and society in general concerning normal development of infants and the significance of early increased infant crying. If effective, there may be important implications for prevention of infant abuse nationally and internationally. PMID:23045677

In the first case, postmortem investigation revealed cardiotoxic death as the result of an interaction between opiates, amphetamine derivatives and oxazepam. In the second case, death followed the administration of amphetamine derivatives and cocaine (xenobiotics known on the illicit drug market as "UFO"). Based on the toxicological postmortem analysis the authors discuss the interpretation of the results in the light of general problems of interactions taking place in toxicokinetic and toxicodynamic phases of intoxication processes.

    Recent attention has been given by researchers to exploring economic abuse strategies used by abusers. However, little research has been conducted to understanding how to conceptualize economic abuse in relation to other forms of abuse. This article examines the factor structure of abusive items from the Scale of Economic Abuse--12 and the Abusive Behavior Inventory through confirmatory factor analyses using data collected with 457 female survivors of abuse. The findings provide evidence for conceptualizing economic abuse as a unique form of abuse moderately correlated with psychological, physical, and sexual forms of abuse. PMID:23946140

    Alcoholic liver disease is a significant contributor to global liver failure. In murine models, chronic ethanol consumption dysregulates PTEN/Akt signaling. Hepatospecific deletion of phosphatase and tensin homolog deleted on chromosome 10 (PTENLKO) mice possess constitutive activation of Akt(s) and increased de novo lipogenesis resulting in increased hepatocellular steatosis. This makes PTENLKO a viable model to examine the effects of ethanol in an environment of preexisting steatosis. The aim of this study was to determine the impact of chronic ethanol consumption and the absence of PTEN (PTENLKO) compared to Alb-Cre control mice (PTENf/f) on hepatocellular damage as evidenced by changes in lipid accumulation, protein carbonylation and alanine amino transferase (ALT). In the control PTENf/f animals, ethanol significantly increased ALT, liver triglycerides and steatosis. In contrast, chronic ethanol consumption in PTENLKO mice decreased hepatocellular damage when compared to PTENLKO pair-fed controls. Consumption of ethanol elevated protein carbonylation in PTENf/f animals but had no effect in PTENLKO animals. In PTENLKO mice, overall hepatic mRNA expression of genes that contribute to GSH homeostasis as well as reduced glutathione (GSH) and oxidized glutathione (GSSG) concentrations were significantly elevated compared to respective PTENf/f counterparts. These data indicate that during conditions of constitutive Akt activation and steatosis, increased GSH homeostasis assists in mitigation of ethanol-dependent induction of oxidative stress and hepatocellular damage. Furthermore, data herein suggest a divergence in EtOH-induced hepatocellular damage and increases in steatosis due to polyunsaturated fatty acids downstream of PTEN. PMID:27124661

    The brain dopamine (DA) system appears to play a crucial role in the reinforcing properties of cocaine. Using PET we had previously shown significant decreases in DA D2 receptors but no changes in DA transporters (DAT) in detoxified cocaine abusers (>1 month after last cocaine use). This study evaluates DAT availability in current cocaine abusers (15 male and 5 female; age = 36.2{+-}5.3 years old) using PET and [C-11]cocaine, as a DAT ligand, and compares it to that in 18 male and 2 female age matched normal controls. Cocaine abusers had a history of abusing 4.2{+-}2.8 gm /week of cocaine for an average of 11.0{+-}4.9 years and their last use of cocaine was 5.4{+-}8 days prior to PET study. DAT availability was obtained using the ratio of the distribution volume in the region of interest (caudate, pulamen) to that in cerebellum which is a function of Bmax./Kd.+1. DAT availability in cocaine abusers did not differ to that in normals (N) (C= 1.78{+-}0.14, N= 1.77{+-}0.13). In addition, there were no differences between the groups in the distribution volume or the Kl (plasma to brain transfer constant) measures for [C-11]cocaine. However, in the normals but not in the abusers striatal DAT availability decreased with age (C: r = -0.07, p = 0.76; N: r = -0.55, p < 0.01). Though this study fails to show group differences in DAT availability between normals and current cocaine abusers it indicates a blunting of the age-related decline in DAT availability in the cocaine abusers. Future studies in older cocaine abusers at different time after detoxification arc required in order to assess if cocaine slows the loss of DAT with age or whether these changes reflect compensation to increased DAT blockade and recover with detoxification.

  12. An overview of prodrug technology and its application for developing abuse-deterrent opioids.

    PubMed

    Gudin, Jeffrey A; Nalamachu, Srinivas R

    2016-01-01

    The Centers for Disease Control and Prevention has classified prescription drug abuse and overdose deaths as an epidemic. Prescription drug overdose is now the leading cause of injury death, with rates that have more than doubled since 1999. This crisis has developed concurrently with the increased prescribing and availability analgesic drugs, especially opioids, resulting from an effort on the part of clinicians to address a critical need for improved pain assessment and treatment. Clinicians have recognized that oftentimes, opioid analgesics are one of the few remaining options for patients who suffer with severe pain. A 2015 fact sheet issued by the Office of National Drug Policy stated: "While we must ensure better access to prescription medications to alleviate suffering, it is also vital that we do all we can to reduce the diversion and abuse of pharmaceuticals." The US Food and Drug Administration has issued guidance that encourages the research and development of abuse-deterrent formulation of opioids which have the potential to curtail abuse. Included among the recommended formulations for development of abuse-deterrent opioids are prodrugs. Prodrugs are chemically modified versions of pharmacological agents that must undergo a biochemical conversion following administration, often by enzymatic cleavage, to free the active drug. Prodrugs may be inherently abuse-deterrent because they are inactive or significantly less active until conversion to the active drug. This requirement for conversion in the GI tract can modify the pharmacokinetic profile and eliminate or reduce the euphoria when abusers change the route of administration. Abusers often attempt to extract the active drug for injection or insufflation. Prodrugs can be designed to be resistant to crushing or dissolving. In this article, we review the concept of prodrugs and introduce and examine the potential of abuse-deterrent opioid prodrugs. PMID:26615852

Method The early maladaptive schemas and parenting origins were compared in 56 opioid abusers and 56 non-opioids abusers. Schemas were assessed by the Young Schema Questionnaire 3rd (short form); and parenting origins were assessed by the Young Parenting Inventory. Results Data were analyzed by multivariate analysis of variance (MANOVA). The analysis showed that the means for schemas between opioid abusers and non-opioid abusers were different. Chi square test showed that parenting origins were significantly associated with their related schemas. Conclusion The early maladaptive schemas and parenting origins in opioid abusers were more than non-opioid abusers; and parenting origins were related to their Corresponding schemas. PMID:22952522

    Previous studies have found childhood sexual abuse to predict suicidal behavior in adulthood. Women in jail suffer disproportionately high rates of childhood sexual abuse and attempted suicide relative to women in the general population. Thus, better understanding the association between childhood sexual abuse and attempted suicide among women in jail may inform prevention, assessment, and treatment initiatives for this at-risk population. This study examined the association between childhood sexual abuse and the onset of attempted suicide across the life span in a nationwide sample of women in jail. Participants included a randomly selected subsample of women (N = 115), drawn from a larger probability sample (N = 491), who completed Life History Calendars, which were coded for the presence/absence of attempted suicide and childhood sexual abuse across life history stages. Survival analysis and Cox regression indicated that women with histories of childhood sexual abuse perpetrated by an adult or a peer were significantly more likely to have attempted suicide across the life span, including increased risk for the onset of attempted suicide in adulthood. This study demonstrates the salience of childhood sexual abuse as a predictor of suicidal behavior among women in jail, and extends previous research by demonstrating the temporal sequence of childhood sexual abuse relative to attempted suicide across the life span. Given these findings, researchers, clinicians, and policymakers should consider further the influence of childhood sexual abuse with regard to the high rates of attempted and completed suicide among women in jail.

    Sexual abuse has physiological and emotional implications. The purpose of this study is to evaluate the neurobiological sequels of childhood sexual trauma by monitoring physiological variables among sexually abused girls and women compared to controls. We assessed posttrauma and traumatic life events of 35 females sexually abused in their childhood (age range 7-51 years) and 25 control females (age range 7-54 years). Electroencephalography, frontalis electromyography, electrodermal activity, and heart rate parameters were recorded while watching sets of pictures representing neutral and trauma-suggestive stimuli. A minority of participants met the Diagnostic and Statistical Manual of Mental Disorders criteria for post-traumatic stress disorder. Abused females displayed significant elevations in heart rate, electromyography, and electroencephalography while viewing allusive stimuli and elevated heart rate while viewing neutral stimuli. The dysfunctional regulation of the physiological stress system associated with child sexual abuse may endanger the victims with various stress and anxiety disorders. PMID:26934544

    The present study investigates the prevalence of posttraumatic stress disorder (PTSD) among a sample of treatment-seeking substance abusers and examines the relationship between PTSD comorbidity and rates of inpatient substance abuse treatment. Eighty-four patients (48 male and 36 female) admitted for detoxification at a private hospital were administered self-report measures of lifetime stressor events, PTSD symptomatology, and prior treatment history. Approximately one quarter of the sample was found to present with significant PTSD symptomatology. Women were more likely than men to have been physically and sexually abused, and women reported experiencing a greater number of traumatic events. Consequently, more women than men were classified as having possible PTSD. With respect to inpatient substance abuse treatment admission rates, the PTSD group reported a greater number of hospitalizations than their non-PTSD counterparts. Implications of these findings for routine trauma screening and more effective treatment for substance abusers with concomitant PTSD are highlighted. PMID:7484319

    Background This study investigated the correlation between risk-taking and relapse among methamphetamine (MA) abusers undergoing the Matrix Model of treatment. Methods This cross-sectional study was conducted on male patients who were stimulant drug abusers undergoing the matrix treatment in the National Center for Addiction Research. A sampling was done using the availability method including 92 male patients. Demographic questionnaires and drug abuse related questionnaire were completed for each patient. Then, Bart’s balloon risk-taking test was administered to the patients. Findings Participants had a mean age ± standard deviation (SD) of 27.59 ± 6.60 years with an age range of 17-29 years. Unemployment, unmarried status, criminal offense, and also addiction family history increased the probability of relapse. In addition, a greater adjusted score of the risk-taking test increased the odds of relapse by more than 97%. The simultaneous abuse of opium and stimulants compared to the abuse of stimulants only, revealed no statistically significant differences for relapse. Patients with higher risk-taking behavior had a more probability of relapse. Conclusion This finding indirectly implies the usefulness of Bart’s risk-taking test in assessing risk-taking behavior in stimulant drug abusers. PMID:27274793

  7. Abusive supervision, psychosomatic symptoms, and deviance: Can job autonomy make a difference?

    Recently, interest in abusive supervision has grown (Tepper, 2000). However, little is still known about organizational factors that can reduce its adverse effects on employee behavior. Based on the Job Demands-Resources Model (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001), we predict that job autonomy acts as a buffer of the positive relationship between abusive supervision, psychosomatic symptoms and deviance. Therefore, when job autonomy is low, a higher level of abusive supervision should be accompanied by increased psychosomatic symptoms and thus lead to higher production deviance. When job autonomy is high, abusive supervision should fail to produce increased psychosomatic symptoms and thus should not lead to higher production deviance. Our model was explored among a sample of 170 supervisor-subordinate dyads from 4 organizations. The results of the moderated mediation analysis supported our hypotheses. That is, abusive supervision was significantly related to production deviance via psychosomatic symptoms when job autonomy was low, but not when job autonomy was high. These findings suggest that job autonomy buffers the impact of abusive supervision perceptions on psychosomatic symptoms, with consequences for production deviance.

    Diagnosis of abuse in children with internal abdominal injury is difficult because of limited published work. We aimed to ascertain the incidence of abdominal injury due to abuse in children age 0-14 years. 20 children (identified via the British Paediatric Surveillance Unit) had abdominal injuries due to abuse and 164 (identified via the Trauma Audit and Research Network) had injuries to the abdomen due to accident (112 by road-traffic accidents, 52 by falls). 16 abused children were younger than 5 years. Incidence of abdominal injury due to abuse was 2.33 cases per million children per year (95% CI 1.43-3.78) in children younger than 5 years. Six abused children died. 11 abused children had an injury to the gut (ten small bowel) compared with five (all age >5 years) who were injured by a fall (relative risk 5.72 [95% CI 2.27-14.4]; p=0.0002). We have shown that small-bowel injuries can arise accidentally as a result of falls and road-traffic accidents but they are significantly more common in abused children. Therefore, injuries to the small bowel in young children need special consideration, particularly if a minor fall is the explanation. PMID:16023514

    Recent advancements in technology (e.g., social networking, texting) have created new ways for dating youth to relate to one another, including in abusive ways via "cyber dating abuse." Cyber dating abuse is a form of teen dating violence that overlaps with other types of abuse (e.g., psychological) but also has several unique characteristics. Given the phenomenon's limited presence in dating violence literature, we focus on identifying how experiencing cyber dating abuse relates to youths' individual behaviors and experiences (e.g., substance use, sexual activity), psychosocial adjustment, school connection, family relationships, and partner relationships. A total of 3,745 youth (52% female, 74% White) in three northeastern states participated in the survey and reported currently being in a dating relationship or having been in one during the prior year. We found that experiences of cyber dating abuse were most significantly correlated with being female, committing a greater variety of delinquent behaviors, having had sexual activity in one's lifetime, having higher levels of depressive symptoms, and having higher levels of anger/hostility. Further, cyber dating abuse appeared somewhat more strongly related to depressive symptoms and delinquency than did other forms of teen dating violence and abuse. PMID:24198083

  10. Exploring the controversy in child abuse pediatrics and false accusations of abuse.

    There is a controversy in child abuse pediatrics between an established corps of child abuse pediatricians aligned with hospital colleagues and law enforcement, and a multi-specialty challenger group of doctors and other medical professionals working with public interest lawyers. The latter group questions the scientific validity of the core beliefs of child abuse pediatricians and believes that there are a substantial number of false accusations of abuse occurring. An unproven primary hypothesis, crafted around 1975 by a small group of pediatricians with an interest in child abuse, lies at the foundation of child abuse pediatrics. With no scientific study, it was hypothesized that subdural hemorrhage (SDH) and retinal hemorrhage (RH) were diagnostic of shaking abuse. That hypothesis became the so-called "shaken baby syndrome." Through the period 1975-1985, in a coordinated manner, these child abuse specialists coalesced under the American Academy of Pediatrics and began working with district attorneys and social workers, informing them of the ways in which their hypothesis could be applied to prosecutions of child abuse and life-altering social service interventions. In a legal context, using then-prevailing evidentiary rules which treated scientific expert testimony as valid if it was "generally accepted" in the field, they represented falsely that there was general acceptance of their hypothesis and therefore it was valid science. As the ability to convict based on this unproven prime hypothesis (SDH and RH equals abuse) increased, some defense attorneys were professionally compelled by their own doubts to reach out to experts from other fields with experience with SDH and RH, trauma, and biomechanics, for second opinions. Medical and legal challenges to the established thinking soon emerged, based on both old and new evidenced-based literature. As the intensity of the controversy increased, the probability of false accusation became more apparent and the need

    The aim of this study was to investigate the effect of Avastin® in combination with gemcitabine and cisplatin (GP) on the tumor growth of A549 tumor-bearing mice and the potential anti-tumor mechanism. A total of 30 human A549 tumor-bearing nude mice were randomly divided into the Avastin, chemotherapy and combined treatment groups for treatment with an intraperitoneal injection of Avastin (5 mg/kg) (Avastin group); an intraperitoneal injection of gemcitabine (4 mg/kg) and cisplatin (4 mg/kg) (chemotherapy group); or intraperitoneal injections of Avastin and GP (combined treatment group). The mice were observed for 30 days and the tumor growth, survival and body weight of the mice in the three groups were analyzed. The protein level of vascular endothelial growth factor (VEGF) in the tumor tissues was analyzed by ELISA. The vascular density and structural changes of the tumor were analyzed using immunohistochemistry. Compared with the Avastin and chemotherapy groups, the tumor growth of mice in the combined treatment group was significantly inhibited, and the survival rate of the mice was increased significantly. No difference in body weight was observed among the three groups of mice (P>0.05). The levels of VEGF in the combined treatment group tumor tissues were significantly reduced compared with those in the chemotherapy group tumor tissues (P<0.05). Furthermore, the vessel density of the tumor tissue in the combined treatment group was significantly reduced compared with that in the chemotherapy group (P<0.05), and the number of normal vessels in the combined treatment group tumors was significantly higher than that in the chemotherapy group tumors after 7 days of treatment (P<0.05). In conclusion, Avastin can significantly decrease the level of VEGF in tumor tissue, inhibit tumor angiogenesis and promote the normalization of tumor vascular structure, which may explain the enhanced efficacy of Avastin in combination with chemotherapy.

    Myocardial infarction after hip fracture but before surgical repair is associated with a 30-day mortality as high as 30 % at 1 month. In Florence, since 2011, hip fractures are referred to a multidisciplinary hip fracture team including internal medicine specialists, anesthesiologists, and orthopaedic surgeons. The aim of the present investigation was to evaluate the clinical characteristics of patients with hip fracture who had at hospital admission a significant increase of troponin (>10 times reference levels), the diagnostic and therapeutic strategies adopted, and overall 1-year survival. Protocol at admission included careful clinical evaluation (including bedside echocardiography) in order to stratify surgical risk and schedule surgery and anaesthesiology strategy. 21/1025 patients had preoperative significant troponin increase. In sixteen patients, a diagnosis of NSTEMI was made, five presented with ST elevation. In five patients with NSTEMI considered at very high surgical risk (ASA ≥ 3, severe cognitive and functional impairment), surgery was not performed. None survived at 1 year. Hip surgery was performed in the other 11. Four underwent coronary revascularization after hip surgery. In this group, 1-year survival was 80 %. Four of five ST elevation patients fulfilled criteria for stress cardiomyopathy confirmed by angiography. Hip surgery was performed, and the patients are alive at 1-year follow-up. Close to 2 % of patients with hip fracture are found to have a significant troponin increase before surgery. Three out of four have an NSTEMI diagnosis. In patients undergoing hip surgery, survival at 1 year is close to 80 %. In patients with ST elevation at admission, stress cardiomyopathy should be considered in the differential diagnosis. This clinical condition is associated with a favourable prognosis after hip surgery. PMID:26563767

    Context Both elder self-neglect and abuse have become increasingly prominent public health issues. The association of either elder self-neglect or abuse with mortality remains unclear. Objective To examine the relationship of elder self-neglect or abuse reported to social services agencies with all-cause mortality among a community-dwelling elderly population. Design, Setting, and Participants Prospective, population-based cohort study (conducted from 1993 to 2005) of residents living in a geographically defined community of 3 adjacent neighborhoods in Chicago, Illinois, who were participating in the Chicago Health and Aging Project (CHAP; a longitudinal, population-based, epidemiological study of residents aged ≥65 years). A subset of these participants had suspected elder self-neglect or abuse reported to social services agencies. Main Outcome Measures Mortality ascertained during follow-up and by use of the National Death Index. Cox proportional hazard models were used to assess independent associations of self-neglect or elder abuse reporting with the risk of all-cause mortality using time-varying covariate analyses. Results Of 9318 CHAP participants, 1544 participants were reported for elder self-neglect and 113 participants were reported for elder abuse from 1993 to 2005. All CHAP participants were followed up for a median of 6.9 years (interquartile range, 7.4 years), during which 4306 deaths occurred. In multivariable analyses, reported elder self-neglect was associated with a significantly increased risk of 1-year mortality (hazard ratio [HR], 5.82; 95% confidence interval [CI], 5.20–6.51). Mortality risk was lower but still elevated after 1 year (HR, 1.88; 95% CI, 1.67–2.14). Reported elder abuse also was associated with significantly increased risk of overall mortality (HR, 1.39; 95% CI, 1.07–1.84). Confirmed elder self-neglect or abuse also was associated with mortality. Increased mortality risks associated with either elder self-neglect or

    Background: Children suffer from attention deficit hyperactivity disorder (ADHD) are very difficult to handle. It can be very frustrating and needs an outstanding tolerance. Behavioral difficulties in ADHD children may increase the risk of child abuse for them. The aim of this research was to compare child abuse, and neglect between ADHD group and normal children. Methods: In this cross-sectional study, 30 ADHD students (10 girls and 20 boys) were selected from regional mental behavior disorder clinics and matched with 30 normal students. Data were collected using Child Abuse Self Report Scale. Descriptive statistics, one-way multivariate analysis of variance (MANOVA) and Least Significant Difference (LSD) was performed by using SPSS software. Result: The result of the research showed that almost 60% of participants had experienced neglect and 35% psychological abuse. Neglect and psychological abuse are more frequent than other maltreatments. Neglect, psychological and physical abuses are significantly higher in the ADHD group. Conclusion: The findings showed that the rates of neglect and psychological abuse are higher in the ADHD group. Therefore, it can be suggested that the society and families should be trained to deal better with ADHD children. PMID:25349848

    Background This study examines the prevalence, correlates, and psychiatric disorders of adults with history of child sexual abuse (CSA). Methods Data were derived from a large national sample of the U.S. population. More that 34,000 adults aged 18 years and older residing in households were face-to-face interviewed in a survey conducted during the 2004–2005 period. Diagnoses were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV version. Weighted means, frequencies, and odds ratios of sociodemographic correlates and prevalence of psychiatric disorders were computed. Logistic regression models were used to examine the strength of associations between child sexual abuse and psychiatric disorders, adjusted for sociodemographic characteristics, risk factors and other axis I psychiatric disorders. Results The prevalence of child sexual abuse was 10.14% (24.8% in men, and 75.2% in women). Child physical abuse, maltreatment, and neglect was more prevalent among individuals with CSA than among those without it. Adults with child sexual abuse history had significantly higher rates of any Axis I disorder and suicide attempts. The frequency, type and number of CSA were significantly correlated with psychopathology. Conclusions The high correlation rates of CSA with psychopathology and increased risk for suicide attempts in adulthood suggest the need for a systematic assessment of psychiatric disorders and suicide risk in these individuals. The risk factors for CSA emphasize the need for health care initiatives geared towards increasing recognition and development of treatment approaches for the emotional sequelae CSA as well as early preventive approaches.

    We examined executive functions using performance tasks in 126 boys aged 6 to 16 years. who attended public schools and therapeutic schools for children with emotional and behavioral problems. Children were further grouped based on the presence or absence of substantiated abuse histories. Based on their abuse histories and schools of origin, children were classified as Therapeutic, Abused (TA, N = 25). Therapeutic, Nonabused (TN, N = 52), and Public School (PS, N = 48). Controlling IQ and medication status, we compared children in the three groups on teacher ratings of behavior, on experimenter observations of behavior during testing, and on performance tasks challenging the capacities to inhibit an act in progress, and to passively avoid responses associated with adverse consequences. We examined mean group differences in symptoms, behaviors, and task performance, as well as differential age-dependent changes in these dimensions. Independent of abuse history, therapeutic school children demonstrated comparable levels of internalizing and externalizing symptoms, and comparable levels of redirections to task during testing-sessions, that were significantly higher than those of the public school children. Both groups of therapeutic school children also showed comparable overall performance on the capacities to inhibit an act in progress, and to passively avoid responses associated with adverse consequences that were poorer than the performance of children from the public school. Children with histories of substantiated abuse showed diminished improvement with increasing age in the capacity to passively avoid responses associated with adverse consequences when compared not only to the public school children, but also to the children from the therapeutic schools without histories of abuse. Our findings complement reports of behavioral observations of abused children, and reports associating child abuse with altered cognitive development in other areas of competence

    Background Substance abuse is a social, and health problem in Middle Eastern countries such as Iran. One of its most devastating effects is domestic violence against children. This study examined the association between the history of parental substance abuse, and rate of child abuse in Ahvaz, Iran. Methods This was a case-control study. The study population included all parents with high school children in Ahwaz within the academic year 2012-2013. The sample size was 384 people in two groups; with a history of substance abuse (case group) and no history of substance abuse (control group). Multi-stage cluster random sampling method was used through the Cochran formula. The data collection tools included a Childhood Trauma Questionnaire (CTQ) (Bernstein, 1995), a demographic questionnaire, Duncan Socioeconomic Index (DSI), and a researcher-made questionnaire for the history of substance abuse. For data analysis, statistical indicators such as percentage, mean, standard deviation, t-test, and correlation and regression analysis were used. Findings Data analysis showed that there was a significant positive correlation among parents with a history of substance abuse and domestic violence toward children. Mean and standard deviation of the violence level in families with normal parents were 61.34 ± 16.88, and in families with a history of substance abuse were 98.99 ± 32.07. Therefore, the test results showed that there was a significant difference between normal families and families with history of substance abuse and violence toward children (P < 0.001, t = 8.60). Conclusion Based on the findings, the history of domestic violence and parental substance abuse (physical and emotional abuse, emotional and physical neglect) had a significant positive correlation with their behavior toward their children. After matching the two groups we found that the most common types of violence against children by their parents were, respectively, emotional violence (r = 58

    Decidual macrophages (DM) are the second most abundant population in the fetal-maternal interface. Their role has been so far identified as being local immuno-modulators favoring the maternal tolerance to the fetus. Herein we investigated tissue samples from 11 cases of spontaneous miscarriages and from 9 cases of elective terminations of pregnancy. Using immunohistochemistry and dual immunofluorescence we have demonstrated that in spontaneous miscarriages the DM are significantly increased. Additionally, we noted a significant up-regulation of macrophage FasL expression. Our results further support a dual role for DM during pregnancy and miscarriages. We hypothesize that the baseline DM population in normal pregnancy is in line with an M2 phenotype supporting the ongoing gestation. In contrast, during spontaneous miscarriages, the increased FasL-expressing population could be a part of an M1 phenotype participating in Fas/FasL-related apoptosis. Our results highlight a new aspect of macrophage biology in pregnancy physiology and pathophysiology. Further studies with larger samples are needed to verify the current results and evaluate their clinical impact. PMID:22942752

Further studies with larger samples are needed to verify the current results and evaluate their clinical impact. PMID:22942752

    The majority of triple-negative breast cancers (TNBCs) are basal-like breast cancers. However there is no reported study on anti-tumor effects of sunitinib in xenografts of basal-like TNBC (MDA-MB-468) cells. In the present study, MDA-MB-231, MDA-MB-468, MCF-7 cells were cultured using RPMI 1640 media with 10% FBS. Vascular endothelia growth factor (VEGF) protein levels were detected using ELISA (R & D Systams). MDA-MB-468 cells were exposed to sunitinib for 18 hours for measuring proliferation (3H-thymidine incorporation), migration (BD Invasion Chamber), and apoptosis (ApopTag and ApoScreen Anuexin V Kit). The effect of sunitinib on Notch-1 expression was determined by Western blot in cultured MDA-MB-468 cells. 10(6) MDA-MB-468 cells were inoculated into the left fourth mammary gland fat pad in athymic nude-foxn1 mice. When the tumor volume reached 100 mm(3), sunitinib was given by gavage at 80 mg/kg/2 days for 4 weeks. Tumor angiogenesis was determined by CD31 immunohistochemistry. Breast cancer stem cells (CSCs) isolated from the tumors were determined by flow cytometry analysis using CD44(+)/CD24(-) or low. ELISA indicated that VEGF was much more highly expressed in MDA-MB-468 cells than MDA-MB-231 and MCF-7 cells. Sunitinib significantly inhibited the proliferation, invasion, and apoptosis resistance in cultured basal like breast cancer cells. Sunitinib significantly increased the expression of Notch-1 protein in cultured MDA-MB-468 or MDA-MB-231 cells. The xenograft models showed that oral sunitinib significantly reduced the tumor volume of TNBCs in association with the inhibition of tumor angiogeneisis, but increased breast CSCs. These findings support the hypothesis that the possibility should be considered of sunitinib increasing breast CSCs though it inhibits TNBC tumor angiogenesis and growth/progression, and that effects of sunitinib on Notch expression and hypoxia may increase breast cancer stem cells.

    A series of 320 German i.v. drug abusers (32.2% female, 67.8% male) were tested in a cross-sectional study for antibodies against HIV. Seroprevalence increased from 0 in those who discontinued i.v. drug abuse before 1982 to 37.2% in those who stopped injecting drugs in 1985/1986 or who were still addicted. Antibodies to HIV were significantly associated with lymphadenopathy and clinical symptoms (fever, weight loss, diarrhea, fatigue, night sweat, dermal lesions) and with markers of hepatitis A and hepatitis B virus infection. Participants of the study admitted in 92.5% of cases to "needle sharing" and in 83.1% of cases to sexual contacts among drug abusers. Prostitution and drug abuse in prison were significantly correlated with seropositivity. No antibodies to HIV infection were detected in 131 subjects of a control group of household contacts.

    Our goal was to evaluate brachial plexus (BP) dose with and without the use of supraclavicular (SCL) irradiation in patients undergoing breast-conserving therapy with whole-breast radiation therapy (RT) after lumpectomy. Using the standardized Radiation Therapy Oncology Group (RTOG)-endorsed guidelines delineation, we contoured the BP for 10 postlumpectomy breast cancer patients. The radiation dose to the whole breast was 50.4 Gy using tangential fields in 1.8-Gy fractions, followed by a conedown to the operative bed using electrons (10 Gy). The prescription dose to the SCL field was 50.4 Gy, delivered to 3-cm depth. The mean BP volume was 14.5 {+-} 1.5 cm{sup 3}. With tangential fields alone, the median mean dose to the BP was 0.57 Gy, the median maximum dose was 1.93 Gy, and the irradiated volume of the BP receiving 40, 45, and 50 Gy was 0%. When the third (SCL field) was added, the dose to the BP was significantly increased (P = .01): the median mean dose to the BP was 40.60 Gy, and the median maximum dose was 52.22 Gy. With 3-field RT, the median irradiated volume of the BP receiving 40, 45, and 50 Gy was 83.5%, 68.5%, and 24.6%, respectively. The addition of the SCL field significantly increases dose to the BP. The possibility of increasing the risk of BP morbidity should be considered in the context of clinical decision making.

    Abstract The cerebellum has been proven to be connected to the brain network, as in the default-mode network (DMN), among healthy subjects and patients with psychiatric disorders. However, whether or not abnormal cerebellar DMN connectivity exists and what its clinical significance is among drug-naive patients with somatization disorder (SD) at rest remain unclear. A total of 25 drug-naive patients with SD and 28 healthy controls were enrolled for a resting-state scan. The imaging data were analyzed using the seed-based functional connectivity (FC) method. Compared with the controls, patients with SD showed increased left/right Crus I-left/right angular gyrus (AG) connectivity and Lobule IX-left superior medial prefrontal cortex (MPFC) connectivity. The FC values of the left/right Crus I-right AG connectivity of the patients were positively correlated with their scores in the somatization subscale of the symptom checklist-90 (Scl-90). A trend level of correlations was observed between the FC values of the left Crus I-left AG connectivity of the patients and their scores for the somatization subscale of Scl-90, as well as between the FC values of their Lobule IX-left superior MPFC connectivity and their scores for the Eysenck personality questionnaire (EPQ) extraversion. Our findings show the increased cerebellar DMN connectivity in patients with SD and therefore highlight the importance of the DMN in the neurobiology of SD. Increased cerebellar DMN connectivities are also correlated with their somatization severity and personality, both of which bear clinical significance. PMID:27428190

    In this study, we investigated associations between susceptibility genes and cerebral infarctions in a Chinese population, and whether gene-gene interactions increase the risk of cerebral infarctions. Overall, 292 patients with cerebral infarctions and 259 healthy control individuals were included. Eight variants in five candidate genes were examined for the risk of stroke, including the SG13S32 (rs9551963), SG13S42 (rs4769060), SG13S89 (rs4769874), and SG13S114 (rs10507391) variants of the 5-lipoxygenase activating protein (ALOX5AP) gene, the G860A (rs751141) variant of the soluble epoxide hydrolase (EPHX2) gene, the A1075C (rs1057910) variant of the CYP2C9*2 gene, the C430T (rs1799853) variant of the CYP2C9*3 gene, and the A6986G (rs776746) variant of the CYP3A5 gene. Gene-gene interactions were explored using generalized multifactor dimensionality reduction methods. There were no statistically significant differences in the frequencies of the genotypes of the eight candidate genes. The generalized multifactor dimensionality reduction analysis showed a significant gene-gene interaction between SG13S114 and A6986G, with scores of 10 for cross-validation consistency and 9 for the sign test (P=0.0107). These gene-gene interactions predicted a significantly higher risk of cerebral infarction (adjusted for age, hypertension, and diabetes mellitus; odds ratio=1.80495%, confidence interval: 1.180-2.759, P=0.006). A two-loci gene interaction confers a significantly higher risk for cerebral infarction. The combinational analysis used in this study may be helpful in the elucidation of genetic risk factors for common and complex diseases. PMID:24368493

    The arbuscular mycorrhizal symbiosis is formed between arbuscular mycorrhizal fungi (AMF) and plant roots. The fungi provide the plant with inorganic phosphate (P). The symbiosis can result in increased plant growth. Although most global food crops naturally form this symbiosis, very few studies have shown that their practical application can lead to large-scale increases in food production. Application of AMF to crops in the tropics is potentially effective for improving yields. However, a main problem of using AMF on a large-scale is producing cheap inoculum in a clean sterile carrier and sufficiently concentrated to cheaply transport. Recently, mass-produced in vitro inoculum of the model mycorrhizal fungus Rhizophagus irregularis became available, potentially making its use viable in tropical agriculture. One of the most globally important food plants in the tropics is cassava. We evaluated the effect of in vitro mass-produced R. irregularis inoculum on the yield of cassava crops at two locations in Colombia. A significant effect of R. irregularis inoculation on yield occurred at both sites. At one site, yield increases were observed irrespective of P fertilization. At the other site, inoculation with AMF and 50% of the normally applied P gave the highest yield. Despite that AMF inoculation resulted in greater food production, economic analyses revealed that AMF inoculation did not give greater return on investment than with conventional cultivation. However, the amount of AMF inoculum used was double the recommended dose and was calculated with European, not Colombian, inoculum prices. R. irregularis can also be manipulated genetically in vitro, leading to improved plant growth. We conclude that application of in vitro R. irregularis is currently a way of increasing cassava yields, that there is a strong potential for it to be economically profitable and that there is enormous potential to improve this efficiency further in the future.

    Objectives: We investigated (1) whether sexual, physical, or emotional abuse experienced either as a child or as an adolescent/adult is associated with symptoms of urinary frequency, urgency, and nocturia, and (2) the extent to which the observed association between abuse and urologic symptoms may be causal. Methods: Analyses are based on data from the Boston Area Community Health (BACH) survey, a community-based epidemiologic study of many different urologic symptoms and risk factors. BACH used a multistage stratified cluster sample to recruit 5506 adults, aged 30[en]79 yr (2301 men, 3205 women; 1770 black [African American], 1877 Hispanic, and 1859 white respondents). Results: The symptoms considered are common, with 33% of BACH respondents reporting urinary frequency, 12% reporting urgency, and 28% reporting nocturia. All three symptoms are positively associated with childhood and adolescent/adult sexual, physical, and emotional abuse (p < 0.05), with abuse significantly increasing the odds of urinary frequency by a factor ranging from 1.6 to 1.9, the odds of urgency by a factor from 2.0 to 2.3, and the odds of nocturia by a factor from 1.3 to 1.5. Conclusions: Our analyses extend previous work. First, we show a strong association between abuse and urinary frequency, urgency, and nocturia in a community-based random sample. Second, we move beyond discussion of statistical association and find considerable evidence to suggest that the relationship between abuse and these symptoms may be causal. PMID:17383083

    Epilepsy is not a regular topic in many countries' schools. Thus many people harbor misconceptions about people suffering from this disease. It was our aim to a) examine what grade ten students know and believe about epilepsy, and b) to develop and test a teaching unit to improve their knowledge and attitude. The test group comprised eight grade ten classes from six different Austrian high schools (54 girls and 51 boys aged 14-17), the control group (no intervention) five grade ten classes from the same schools (26 girls and 37 boys aged 14-17). The teaching unit consisted of three 45-min lessons using different methods and material. Changes in knowledge about and attitude towards epilepsy as a result of the intervention were psychometrically assessed in a pre-test intervention post-test design (along with a follow-up assessment two months after the intervention) by means of a questionnaire capturing different facets of epilepsy-related knowledge and attitude. Across all knowledge/attitude domains, students of the test group had a significantly improved knowledge about and a more positive attitude towards epilepsy and people suffering from it after the teaching unit. However, starting levels were different between the five knowledge/attitude domains tested. Medical background knowledge was lowest and consequently associated with the highest increase after the intervention. This study shows that epilepsy-related knowledge of many grade ten high school students is fragmentary and that some harbor beliefs and attitudes which require improvement. Our comprehensive but concise teaching unit significantly increased knowledge about epilepsy and positively influenced attitude towards individuals with epilepsy. Thus we recommend implementing this unit into regular school curricula. PMID:26919557

    Background Amiodarone is a frequently used antiarrhythmic drug in patients with end-stage heart failure. Given its long half-life, pre-transplant use of amiodarone has been controversially discussed, with divergent results regarding morbidity and mortality after heart transplantation (HTX). Aim The aim of this study was to investigate the effects of long-term use of amiodarone before HTX on early post-transplant atrial fibrillation (AF) and mortality after HTX. Methods Five hundred and thirty patients (age ≥18 years) receiving HTX between June 1989 and December 2012 were included in this retrospective single-center study. Patients with long-term use of amiodarone before HTX (≥1 year) were compared to those without long-term use (none or <1 year of amiodarone). Primary outcomes were early post-transplant AF and mortality after HTX. The Kaplan–Meier estimator using log-rank tests was applied for freedom from early post-transplant AF and survival. Results Of the 530 patients, 74 (14.0%) received long-term amiodarone therapy, with a mean duration of 32.3±26.3 months. Mean daily dose was 223.0±75.0 mg. Indications included AF, Wolff–Parkinson–White syndrome, ventricular tachycardia, and ventricular fibrillation. Patients with long-term use of amiodarone before HTX had significantly lower rates of early post-transplant AF (P=0.0105). Further, Kaplan–Meier analysis of freedom from early post-transplant AF showed significantly lower rates of AF in this group (P=0.0123). There was no statistically significant difference between patients with and without long-term use of amiodarone prior to HTX in 1-year (P=0.8596), 2-year (P=0.8620), 5-year (P=0.2737), or overall follow-up mortality after HTX (P=0.1049). Moreover, Kaplan–Meier survival analysis showed no statistically significant difference in overall survival (P=0.1786). Conclusion Long-term use of amiodarone in patients before HTX significantly reduces early post-transplant AF and is not associated with

    Autism spectrum disorder (ASD) is increasingly being recognized as an important issue in adult psychiatry and psychotherapy. High intelligence indicates overall good brain functioning and might thus present a particularly good opportunity to study possible cerebral correlates of core autistic features in terms of impaired social cognition, communication skills, the need for routines, and circumscribed interests. Anatomical MRI data sets for 30 highly intelligent patients with high-functioning autism and 30 pairwise-matched control subjects were acquired and analyzed with voxel-based morphometry. The gray matter volume of the pairwise-matched patients and the controls did not differ significantly. When correcting for total brain volume influences, the patients with ASD exhibited smaller left superior frontal volumes on a trend level. Heterogeneous volumetric findings in earlier studies might partly be explained by study samples biased by a high inclusion rate of secondary forms of ASD, which often go along with neuronal abnormalities. Including only patients with high IQ scores might have decreased the influence of secondary forms of ASD and might explain the absence of significant volumetric differences between the patients and the controls in this study.

    The drivers of angiosperm diversity have long been sought and the flower-arthropod association has often been invoked as the most powerful driver of the angiosperm radiation. We now know that features that influence arthropod interactions cannot only affect the diversification of lineages, but also expedite or constrain their rate of extinction, which can equally influence the observed asymmetric richness of extant angiosperm lineages. The genus Asarum (Aristolochiaceae; ∼100 species) is widely distributed in north temperate forests, with substantial vegetative and floral divergence between its three major clades, Euasarum, Geotaenium, and Heterotropa. We used Binary-State Speciation and Extinction Model (BiSSE) Net Diversification tests of character state distributions on a Maximum Likelihood phylogram and a Coalescent Bayesian species tree, inferred from seven chloroplast markers and nuclear rDNA, to test for signal of asymmetric diversification, character state transition, and extinction rates of floral and vegetative characters. We found that reduction in vegetative growth, loss of autonomous self-pollination, and the presence of putative fungal-mimicking floral structures are significantly correlated with increased diversification in Asarum. No significant difference in model likelihood was identified between symmetric and asymmetric rates of character state transitions or extinction. We conclude that the flowers of the Heterotropa clade may have converged on some aspects of basidiomycete sporocarp morphology and that brood-site mimicry, coupled with a reduction in vegetative growth and the loss of autonomous self-pollination, may have driven diversification within Asarum.

    Reassortment between different influenza viruses is a crucial way to generate novel influenza viruses with unpredictable virulence and transmissibility, which may threaten the public health. As currently in China, avian influenza viruses (AIVs) of H9N2 and H5N1 subtypes are endemic in poultry in many areas, while they are prone to reassort with each other naturally. In order to evaluate the risk of the reassortment to public health, A/Goose/Jiangsu/k0403/2010 [GS/10(H5N1)] virus was used as a backbone to generate a series of reassortants, each contained a single internal gene derived from the predominant S genotype of the A/Chicken/Jiangsu/WJ57/2012 [WJ/57(H9N2)]. We next assessed the biological characteristics of these assortments, including pathogenicity, replication efficiency and polymerase activity. We found that the parental WJ/57(H9N2) and GS/10(H5N1) viruses displayed high genetic compatibility. Notably, the H5N1 reassortants containing the PA or NP gene from WJ/57(H9N2) virus significantly increased virulence and replication ability in mice, as well as markedly enhanced polymerase activity. Our results indicate that the endemicity of H9N2 and H5N1 in domestic poultry greatly increases the possibility of generating new viruses by reassortment that may pose a great threat to poultry industry and public health.

    Humans do not generally walk at constant speed, except perhaps on a treadmill. Normal walking involves starting, stopping and changing speeds, in addition to roughly steady locomotion. Here, we measure the metabolic energy cost of walking when changing speed. Subjects (healthy adults) walked with oscillating speeds on a constant-speed treadmill, alternating between walking slower and faster than the treadmill belt, moving back and forth in the laboratory frame. The metabolic rate for oscillating-speed walking was significantly higher than that for constant-speed walking (6-20% cost increase for ±0.13-0.27 m s(-1) speed fluctuations). The metabolic rate increase was correlated with two models: a model based on kinetic energy fluctuations and an inverted pendulum walking model, optimized for oscillating-speed constraints. The cost of changing speeds may have behavioural implications: we predicted that the energy-optimal walking speed is lower for shorter distances. We measured preferred human walking speeds for different walking distances and found people preferred lower walking speeds for shorter distances as predicted. Further, analysing published daily walking-bout distributions, we estimate that the cost of changing speeds is 4-8% of daily walking energy budget. PMID:26382072

    The article presents the results of a study that examined Palestinian physicians' misconceptions about abused wives and abusive husbands and the extent to which Palestinian physicians approve of wife abuse. Self-administered questionnaires were completed by 396 physicians. The results revealed that between 10% and 49% of the Palestinian physicians held misconceptions about abused wives and between 15% and 63% held misconceptions about abusive husbands. The findings also revealed that substantial percentages of physicians tended to approve of moderate and severe violence against wives. Significant amounts of the variance in the physicians' approval of moderate and severe wife abuse can be attributed to their exposure to family violence and to their patriarchal ideology-variance over and above that which can be explained by the physicians' sociodemographic characteristics. The limitations of the study are discussed, as are the implications of the results for future research and theory development on the approaches of professionals toward wife abuse. PMID:19531634

    "Shaken baby syndrome" is a term often used by the physicians and public to describe abusive trauma inflicted on infants and young children. Advances in the understanding of the mechanisms and the associated clinical spectrum of injury has lead us to modify our terminology and address it as "abusive trauma" (AT). Pediatric abusive head trauma is defined as an injury to the skull or intracranial contents of an infant or a young child (< 5 y age) due to inflicted blunt impact and/or violent shaking. This chapter focuses on the imaging aspects of childhood abusive trauma along with a brief description of the mechanism and pathophysiology of abusive injury. The diagnosis of AT is not always obvious, and abusive injuries in many infants may remain unrecognized. Pediatricians should be cognizant of AT since pediatricians play a crucial role in the diagnosis, management and prevention of AT. PMID:26882906

Therefore, we collected saliva samples three times daily for 3 days to assess concentrations of salivary alpha amylase (sAA) – a surrogate marker for autonomic nervous system (ANS) activity and, in particular, sympathetic activity – in sexually abused adolescent girls. Methods: Twenty-four girls (mean age: 15±1.4 years) who had experienced recent sexual abuse (i.e., sexual abuse occurred 1–6 months prior to study enrollment) and 12 healthy comparison subjects (mean age: 14.8±1.3 years) completed a structured interview and assessments to ascertain symptoms of posttraumatic stress, then collected saliva at home upon awakening, 30 minutes after waking, and at 5 p.m. on three consecutive school days. Results: For sexually abused girls, total PTSD symptoms were associated with higher overall morning levels of sAA (r[20]=0.51, p=0.02), a finding driven by intrusive symptoms (r[20]=0.43, p<0.05) and hyperarousal symptoms (r[20]=0.58, p=0.01). There were no significant differences in diurnal sAA secretion between the sexually abused girls and healthy comparison adolescents. Conclusions: Overall morning concentrations of sAA in sexually abused girls are associated with overall PTSD severity as well as symptoms of hyperarousal and intrusive symptoms, possibly reflecting symptom-linked increases in ANS tone. These data raise the possibility that alterations in ANS activity are related to the pathophysiology of sexual abuse-related PTSD in adolescent girls, and may inform therapeutic interventions (e.g., antiadrenergic medications).

    There has been increasing awareness that sexual abuse of children is a problem in Malaysia. Existing data is based on notification of cases. Population based studies are required to plan services for sexually abused children. This study utilized trainee paramedical staff as a community population to determine the prevalence of childhood sexual abuse. An anonymous, self-administered questionnaire was given to student nurses and trainee medical assistants at the Ipoh School of Nursing and Hospital Bahagia Medical Assistant Training School. Questionnaires were distributed directly to all students in a classroom setting and retrieved after a 30-minute interval. Information collected included questions on personal experiences of sexual abuse. Sexual abuse was defined as rape, sodomy, molestation, or exhibitionism occurring to a child less than 18 years of age. Six hundred and sixteen students participated in the study; 6.8% of the students admitted to having been sexually abused in their childhood, 2.1% of males and 8.3% of females. Of those abused, 69% reported sexual abuse involving physical contact, 9.5% of whom experienced sexual intercourse. The age at first abuse was < 10 years in 38.1% of the cases; 59.5% were repeatedly abused and 33.3% had more than one abuser. Of the abusers, 71.4% were known to the respondent, 14.2% of whom were brothers, 24.5% relatives, and 24.5% a family friend. Further, 28.9% of all students knew of an individual who had been sexually abused as a child. While this population may not be entirely reflective of the community, this study does provide an indication of the prevalence of sexual abuse in Malaysian children. The prevalence figures in this study are lower than those reported in industrialized countries and this may reflect local sociocultural limitations in reporting abuse. PMID:8800523

  6. Worldwide actions to combat abuse.

    This paper reports several developments on the global efforts to combat abuse and violence against women and children. It is noted that in South Africa, Belem, Brazil, and Lesotho, protest actions were conducted against women and child abuse. Although the protests were made separately, the protests generally called for implementation of initiatives from the government to address the issue of child and women abuse. In the context of preventing abusive behaviors, a study by the University of Cape Town in South Africa on the appropriateness and feasibility of short-term community-based group therapy concluded that such an approach might be effective in treating delinquent behavior. In Indonesia, the Rifka Annisa Women's Crisis Centre is working to combat violence against women by providing services to victims; while in Israel, a media campaign is aiming to increase awareness and support for women's help centers. In addition, the government of Bangladesh has established a Cell Against Violence Against Women that provides legal counseling and assistance for civil and criminal cases related to violence against women. Furthermore, the WHO and the International Federation of Obstetricians and Gynecologists have collaborated to conduct a joint workshop to explore how violence against women can be eliminated.

    Within the theoretical framework of Ryle's Procedural Sequence Object Relations Model and Kelly's Personal Construct Theory, this study investigates sex-role polarization of incest survivors and the centrality of abuse within survivors' constructs of men that may contribute to revictimization. Repertory grid methodology was used with 40 female survivors of childhood sexual abuse and 28 non-abused women. Grid measures and psychometric measures were compared between groups of women who had and had not experienced childhood sexual abuse, revictimized and non-revictimized survivors, and survivors who had and had not experienced incestuous abuse. Results showed significant differences between survivors and non-abused women, with survivors having higher levels of depression and perceived distress, lower self-esteem and higher self/ ideal self discrepancy. Hypothesized differences in sex-role polarization were not found. There were few differences between revictimized and non-revictimized survivors, although revictimized survivors rated 'self now' as more powerful than non-revictimized survivors. No differences were found between survivors who had and had not experienced incestuous abuse. In addition to the value of exploring personal constructs, a range of models need to be considered in understanding revictimization and women's construal of men. The implications of using repertory grid methodology for research and clinical work are discussed. PMID:11589329

    While it has been steadily declining since the 1960s, though at a slower pace over the last 5 years, the average alcohol consumption per capita and per year in France remains one of the highest in Europe. The available general population surveys reveal that the most visible change is the type of alcohol abuse. Two emerging trends have been observed over the last ten years, and seem to be worsening: the transfer from daily drinking to weekend drinking, and the increase in isolated risk-taking related to acute alcoholization associated with more-or-less conscious inebriation episodes. These changes require adapting prevention messages, the development of alcohol risk screening strategies in emergency units and the assessment of therapeutic programs aiming at reducing the risks of alcohol consumption rather than maintaining abstinence.

    Substance abuse and addiction represent a worldwide problem and cause a number of family, social and health problems. Digestive system damage caused by substance intake is an increasing problem amoung drug addicts. Many studies show that substances can cause cancer of all parts of the digestive system. Alcohol consumption was significantly associated with colon and rectal cancer. For rectal cancer, the risk was increased in association with drinking of alcoholic beverages, specialy for beer consumption. Sinthetic drugs such as ecstasy may lead also to digestive and hepatic damage, as well as vascular complications of the stomach. Many studies show the existance of supstance associated enterocolitis as well as ishemic colitis. Diagnosis of ishemic colitis is based on the presence of rectal bleeding, abdominal pain, a history of substance use, supportive endoscopic and histopathologic findings, and the absence of other etiologic mechanisms of ischemic colitis. Great damage to the digestive system is also produced by smuggling narcotics packed into small pages that are afterwards been swallowed or implemented on other sorts of ways inside the smugglers natural body spaces as the rectum or vagina. In the paper authors reviewed literature conserning digestive system damage caused by substance abuse and drug smuggling. PMID:19069706

    A not moderate alcohol consumption or its abuse have relevant consequences not only on the health of the general population but also on the possibility to carry out any work in safety conditions. These behaviours have focused the attention of the institutions, which have promoted in the last years a growing number of preventive and informative actions and have adopted specific laws that have significantly involved the figure of occupational physician. Over the clinical implications, in fact, those behaviours, in the employment context, are associated with an increased risk of injuries (from 10 to 30% of total), an increase in the number of absences from work, with greater precariousness, with the possible interaction and/or strengthening of other occupational toxics and with the progressive reduction of working capacity. Diagnostic tools available for the detection of alcohol abuse or dependency consist, in acute cases by direct measuring of alcohol on blood, saliva and exhaled air, while in the chronic situations in addiction to the more traditional indicators (AST, ALT, GGT, MCV) there are recently introduced marker (CDT)--or in validation (ethyl glucuronide)--that representing, also with specific questionnaires (AUDIT, MAST, MALT, CAGE), useful integrated tools in the clinical-diagnostic path. The role and contribution of occupational medicine in the management of alcohol related problems is vital and relevant. Must be clear however that these are problems associated with a particular behaviour of the person and not with risks present on work-site. PMID:19288791

    A double-network (DN) gel, which was composed of poly(2-acrylamido-2-methylpropanesulfonic acid) and poly(N,N'-dimethyl acrylamide) (PAMPS/PDMAAm), has the potential to induce chondrogenesis both in vitro and in vivo. The present study investigated the biomechanical and biological responses of chondrogenic progenitor ATDC5 cells cultured on the DN gel. ATDC5 cells were cultured on a polystyrene surface without insulin (Culture 1) and with insulin (Culture 2), and on the DN gel without insulin (Culture 3). The cultured cells were evaluated using micropipette aspiration for cell Young's modulus and qPCR for gene expression of chondrogenic and actin organization markers on days 3, 7 and 14. On day 3, the cells in Culture 3 formed nodules, in which the cells exhibited an actin cortical layer inside them, and gene expression of type-II collagen, aggrecan, and SOX9 was significantly higher in Culture 3 than Cultures 1 and 2 (p<0.05). Young's modulus in Culture 3 was significantly higher than that in Culture 1 throughout the testing period (p<0.05) and that in Culture 2 on day 14 (p<0.01). There was continuous expression of actin organization markers in Culture 3. This study highlights that the cells on the DN gel increased the modulus and mRNA expression of chondrogenic markers at an earlier time point with a greater magnitude compared to those on the polystyrene surface with insulin. This study also demonstrates a possible strong interrelation among alteration of cell mechanical properties, changes in actin organization and the induction of chondrogenic differentiation.

    Potential human immunodeficiency virus transmission makes prompt disclosure of child sexual abuse in Africa critical. The pattern of disclosure of 133 children presenting to the largest hospital in Malawi were analyzed. Eighty percent presented early enough for effective use of HIV postexposure prophylaxis. Seventy-five percent of children made a disclosure of child sexual abuse; 29% spontaneously and 47% after prompting. Disclosures were most commonly made to a parent, and age did not affect the pattern of disclosure. The number of children reporting child sexual abuse is increasing, possibly because of increasing awareness, availability of services, and fear of HIV. Although prompt disclosure rates were relatively high, facilitating easier disclosure of child sexual abuse by a free telephone help-line and better training of teachers may be helpful.

    In the decades since Dr. John Caffey described a series of children with chronic subdural hematoma and long bone fractures, there has been a substantial increase in the medical recognition of various forms child abuse. In the United States, the term shaken baby syndrome was coined to explain a constellation of injuries assumed to be the result of violent shaking of infants. After improved understanding of the variety of mechanisms that occur when children are abused, abusive head trauma (AHT) has become the recommended terminology. AHT is a more comprehensive term that reflects the brain injuries that children suffer as the result of abuse. AHT continues to include shaking as a mechanism of injury as well as shaking with impact, impact alone, crushing injuries or combinations of several mechanisms. The medical community in the United States has led the way in developing new terminology and research to describe this unique and devastating form of abuse. The globalization of medicine and rapid information transfer has resulted in AHT becoming well-recognized internationally as a form of serious and fatal child abuse. This paper will review the historical basis in the United States for the diagnosis of AHT. We will also review some of the current international issue in epidemiology, diagnosis, legal processes and outcomes in selected countries/regions where child abuse physicians are actively involved in the evaluation of AHT.

    XynII from Volvariella volvacea has high sodium dodecyl sulfate (SDS) resistance, with the potential for industrial applications under harsh conditions. It consists of a single glycoside hydrolase family 10 (GH10) catalytic domain but contains an additional unique 10 and 4 amino acid residues at the N- and C-terminus, respectively. In this study, five XynII derivatives with N- and/or C-terminus deletions were constructed to determine the effects of these regions on enzyme activity, substrate specificity, thermostability, and SDS resistance. Our results revealed that N- and/or C-terminal truncations significantly increased enzyme activity and thermostability, but reduced SDS resistance. Specifically, the XynIIΔNC4 mutant had 2.53-fold more catalytic efficiency (k cat/K m) towards beechwood xylan than wild-type and 3.0-fold more thermostability (t 1/2 [55°C]). XynIIΔNC4 displayed 3.33-, 4.38-, 1.37-, and 1.98-fold more activity against xylotriose, xylotetraose, xylopentaose, and xylohexaose, respectively, than XynII did. However, its half-life (t 1/2) in 4 % SDS was only 1.72 h, while that of XynII was 4.65 h. Circular dichroism analysis revealed that deletion of N- and C-terminal segments caused minor changes in secondary structure. Our observations suggest that the extra N- and C-terminal segments in wild-type XynII evolved to strengthen the interaction between these regions of the protein, making the local structure more rigid and reducing structural flexibility. In this way, N- and C-terminal truncations increased the thermostability and activity of XynII on different xylans and linear xylooligosaccharides, but reduced its resistance to SDS. PMID:26621803

    The purpose of this study was to evaluate the correlation of expression of phosphorylated methyl-CpG binding protein 2-Ser421 (MeCP2-S421) and VEGF in the membranes of patients with PDR. We examined the expression of phospho-MeCP2-S80, S421, VEGF and PEDF in surgically excised PDR membranes from 33 patients with diabetes, and idiopathic epiretinal membranes from 11 patients without diabetes, using immunohistochemistry and western blot. The colocalization of MeCP2-S421 with VEGF, PEDF, CD31, GFAP and αSMA was revealed by fluorescent double labeling. The effect of CoCl2 and knock down MeCP2 using specific siRNA on the expression of MeCP2 and VEGF were analyzed in HUCAC cells by Western blot. We found that phospho-MeCP2-S421 was significantly increased in the membranes from the patients with PDR compared with the specimens from patients without diabetes (P < 0.01). The expression of phospho-MeCP2-S421 was much stronger than that of phospho-MeCP2-S80 in the PDR membranes. Double labeling showed that the high phospho-MeCP2-S421 expression was associated with strong expression of VEGF, but not PEDF. Further, phospho-MeCP2-S421 and VEGF were increased by the stimulation of CoCl2 and knock down MeCP2 inhibited the expression of VEGF. Our result suggests that phospho-MeCP2-S421 might involve in the pathogenesis of PDR. PMID:27616658

    Low iron and high phytic acid content make fonio based meals a poor source of bioavailable iron. Phytic acid degradation in fonio porridge using whole grain cereals as phytase source and effect on iron bioavailability when added to iron fortified fonio meals were investigated. Grains, nuts and seeds collected in Mali markets were screened for phytic acid and phytase activity. We performed an iron absorption study in Beninese women (n = 16), using non-dephytinised fonio porridge (FFP) and dephytinised fonio porridge (FWFP; 75% fonio-25% wheat), each fortified with 57Fe or 58Fe labeled FeSO4. Iron absorption was quantified by measuring the erythrocyte incorporation of stable iron isotopes. Phytic acid varied from 0.39 (bambara nut) to 4.26 g/100 g DM (pumpkin seed), with oilseeds values higher than grains and nuts. Phytase activity ranged from 0.17±1.61 (fonio) to 2.9±1.3 phytase unit (PU) per g (whole wheat). Phytic acid was almost completely degraded in FWFP after 60 min of incubation (pH≈5.0, 50°C). Phytate∶iron molar ratios decreased from 23.7∶1 in FFP to 2.7∶1 in FWFP. Iron fortification further reduced phytate∶iron molar ratio to 1.9∶1 in FFP and 0.3∶1 in FWFP, respectively. Geometric mean (95% CI) iron absorption significantly increased from 2.6% (0.8–7.8) in FFP to 8.3% (3.8–17.9) in FWFP (P<0.0001). Dephytinisation of fonio porridge with intrinsic wheat phytase increased fractional iron absorption 3.2 times, suggesting it could be a possible strategy to decrease PA in cereal-based porridges.

    In recent years, increasing attention has been paid to web-based learning although the advantages of computer-aided instruction over traditional teaching formats still need to be confirmed. This study examined whether participation in an online module on the differential diagnosis of dyspnoea impacts on student performance in a multiple choice examination of factual knowledge in cardiology and pneumology. A virtual problem-based learning environment for medical students supervised by postgraduate teachers was created. Seventy-four out of 183 fourth-year medical students volunteered to use the online module while attending a 6-week cardio-respiratory curriculum in summer 2007. Of these, 40 were randomly selected to be included (intervention group); the remaining 34 served as an internal control group. Analysis of all written exams taken during the preceding term showed that both groups were comparable (86.4 ± 1.1 vs. 85.9 ± 1.1%; p = 0.751). Students in the intervention group scored significantly higher in the final course assessment than students allocated to the control group (84.8 ± 1.3 vs. 79.5 ± 1.4%; p = 0.006; effect size 0.67). Thus, additional problem-based learning with an online module as part of an undergraduate cardio-respiratory curriculum lead to higher students’ scores in an exam testing factual knowledge. Whether using this teaching format increases overall student motivation to engage in the learning process needs to be further investigated. PMID:19774475

    Some studies have linked birth defects, disability, and chronic illness with an increased incidence of child abuse. Nurses who are involved with disabled children face a challenge in preventing child abuse and intervening in cases in which abuse has occurred. Nurse must become aware of the risk factors and signs of abuse, understand the role of their personal attitudes toward abuse and abusers, and develop the skills to intervene effectively and deal with abusers. Thus, the authors of this article undertook a study to ascertain nurses' attitudes about emotional, sexual, and physical abuse of children with disabilities and to determine if nurses' anticipated level of comfort differed when dealing with abusers of children with disabilities in contrast to abusers of children without disabilities.

    Objectives Commercial curcumin (CU), derived from food spice turmeric (TU), has been widely studied as a potential therapeutic for a variety of oncological and inflammatory conditions. Lack of solubility/bioavailability has hindered curcumin's therapeutic efficacy in human diseases. We have solubilised curcumin in water applying heat/pressure, obtaining up to 35-fold increase in solubility (ultrasoluble curcumin (UsC)). We hypothesised that UsC or ultrasoluble turmeric (UsT) will ameliorate systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS)-like disease in MRL-lpr/lpr mice. Methods Eighteen female MRL-lpr/lpr (6 weeks old) and 18 female MRL-MpJ mice (6 weeks old) were used. Female MRL-lpr/lpr mice develop lupus-like disease at the 10th week and die at an average age of 17 weeks. MRL-MpJ mice develop lupus-like disease around 47 weeks and typically die at 73 weeks. Six mice of each strain received autoclaved water only (lpr-water or MpJ-water group), UsC (lpr-CU or MpJ-CU group) or UsT (lpr-TU or MpJ-TU group) in the water bottle. Results UsC or UsT ameliorates SLE in the MRL-lpr/lpr mice by significantly reducing lymphoproliferation, proteinuria, lesions (tail) and autoantibodies. lpr-CU group had a 20% survival advantage over lpr-water group. However, lpr-TU group lived an average of 16 days shorter than lpr-water group due to complications unrelated to lupus-like illness. CU/TU treatment inhibited lymphadenopathy significantly compared with lpr-water group (p=0.03 and p=0.02, respectively) by induction of apoptosis. Average lymph node weights were 2606±1147, 742±331 and 385±68 mg, respectively, for lpr-water, lpr-CU and lpr-TU mice. Transferase dUTP nick end labelling assay showed that lymphocytes in lymph nodes of lpr-CU and lpr-TU mice underwent apoptosis. Significantly reduced cellular infiltration of the salivary glands in the lpr-TU group compared with the lpr-water group, and a trend towards reduced kidney damage was observed in

    It is interesting that there is scant research of abuse of parents by their children and no study was found on the abuse of parents by their attention deficit hyperactivity disorder (ADHD) children. Seventy-four children and adolescents suffering from ADHD and their parents were interviewed. The diagnoses were made according to DSM-IV diagnostic criteria. A questionnaire was developed to assess the children's abuse toward parents. More than half of the parents are suffering from at least one of the forms of abuse by their ADHD children. Scores of parental abuse were not related to gender. Different types of abuse correlated with oppositional defiant disorder (ODD), tic, and separation anxiety disorder (SAD). Fathers' and mothers' age, the level of education, and type of occupation were not risk factors of the abuse scores. ODD and mother's major depressive disorder were predictors of the abuse. There was a very disturbing high rate of abuse by children against parents. There is an interrelation of different forms of abuse. This study contributes to increasing awareness on the abuse of parents by their ADHD children. PMID:19820986

    Objective The purpose of this paper is to review the experience with the frameless, anchored, GyneFix copper-releasing intrauterine contraceptive devices (IUCDs/IUDs) (Contrel Europe, Belgium), and to demonstrate their high acceptability and low rate of discontinuation of use, which could contribute to current efforts that aim to reduce radically the high number of unintended pregnancies and induced abortions, particularly in young women. Materials and methods This paper is based on studies that examined the differences in uterine volume and cavity size, related to age and parity, and on original clinical research data and practical experience with frameless copper IUDs, as well as on literature data on the IUD–endometrial cavity relationship of conventional IUDs, with special reference to side effects and user discontinuation. Results The mean transverse diameter in nulliparous and parous women is significantly less than the length of the transverse arm of the TCu380A IUD (ParaGard, Duramed, NY, USA) or the levonorgestrel intrauterine system (Mirena, Bayer, Germany). Small, frameless, flexible, and unidimensional copper IUDs appear to be well tolerated, with less impact on menstrual bleeding, resulting in low discontinuation rates when compared with standard-size conventional IUDs, which often result in increased expulsion rates, complaints of pain and erratic or increased menstrual bleeding, and subsequent high rates of discontinuation, particularly in young women. Conclusion The unidimensional GyneFix IUDs fit the majority of uterine cavities. An IUD that fits is likely to result in increased tolerance and continued use of the method. As this would appeal to women, the logical result should be greater use of the method and fewer unintended pregnancies and induced abortions. Recommending the standard TCu380A (ParaGard) IUD or the Mirena levonorgestrel intrauterine system, primarily developed for use in parous women, for general use in nulliparous and adolescent

    The herbicide atrazine (2-chloro-4-[ethylamino]-6-[isopropylamino]-s-triazine) is the most common water contaminant in the United States. Atrazine is a phosphodiesterase inhibitor and is classified as an estrogen disrupting compound because it elevates estrogen levels via induction of the enzyme aromatase. Previous studies have shown that atrazine exposure alters the function of innate immune cells such as NK cells, DC, mast cells, and macrophages. In this study we have examined the impact of in vitro atrazine exposure on the activation, proliferation, and effector cytokine production by primary murine CD4(+) T lymphocytes. We found that atrazine exposure significantly inhibited CD4(+) T cell proliferation and accumulation as well as the expression of the activation markers CD25 and CD69 in a dose-dependent manner. Interestingly, the effects were more pronounced in cells from male animals. These effects were partially mimicked by pharmacological reagents that elevate intracellular cAMP levels and addition of exogenous rmIL-2 further inhibited proliferation and CD25 expression. Consistent with these findings, atrazine exposure during T cell activation resulted in a 2- to 5-fold increase in the frequency of Foxp3(+) CD4(+) T cells. PMID:25433234

    High oleic oil is an important industrial feedstock that has been one of the main targets for oil improvement in a number of oil crops. Crambe (Crambe abyssinica) is a dedicated oilseed crop, suitable for industrial oil production. In this study, we down-regulated the crambe fatty acid desaturase (FAD) and fatty acid elongase (FAE) genes for creating high oleic seed oil. We first cloned the crambe CaFAD2, CaFAD3 and CaFAE1 genes. Multiple copies of each of these genes were isolated, and the highly homologous sequences were used to make RNAi constructs. These constructs were first tested in Arabidopsis, which led to the elevated oleic or linoleic levels depending on the genes targeted, indicating that the RNAi constructs were effective in regulating the expression of the target genes in nonidentical but closely related species. Furthermore, down-regulation of CaFAD2 and CaFAE1 in crambe with the FAD2-FAE1 RNAi vector resulted in even more significant increase in oleic acid level in the seed oil with up to 80% compared to 13% for wild type. The high oleic trait has been stable in subsequent five generations and the GM line grew normally in greenhouse. This work has demonstrated the great potential of producing high oleic oil in crambe, thus contributing to its development into an oil crop platform for industrial oil production. PMID:25998013

    The current study examined three well-established risk factors for intimate partner aggression (IPA) within Finkel and Eckhardt's I(3) model, including two impellance factors-trait anger and childhood physical abuse history-and the disinhibiting factor of alcohol consumption. Participants were 236 male and female college students in a committed heterosexual dating relationship who completed a battery of self-report measures assessing childhood physical abuse, trait anger, alcohol consumption, and IPA perpetration. Results revealed a significant three-way interaction showing that as the disinhibition factor alcohol consumption increased, the interaction of the two impelling factors, trait anger and childhood physical abuse, became increasingly more positive. Individuals who had high levels of childhood physical abuse and alcohol consumption were at greater risk of IPA perpetration when trait anger was high. Consistent with the I(3) model, these findings suggest that trait anger and a history of childhood physical abuse may increase tendencies to aggress against one's partner, whereas alcohol consumption may reduce individuals' abilities to manage these aggressive tendencies. The importance of interplay among these risk factors in elevating IPA risk is discussed, as are the implications for clinicians working with male and female IPA perpetrators. PMID:25012954

    Objectives. This 11-city study sought to identify risk factors for femicide in abusive relationships. Methods. Proxies of 220 intimate partner femicide victims identified from police or medical examiner records were interviewed, along with 343 abused control women. Results. Preincident risk factors associated in multivariate analyses with increased risk of intimate partner femicide included perpetrator’s access to a gun and previous threat with a weapon, perpetrator’s stepchild in the home, and estrangement, especially from a controlling partner. Never living together and prior domestic violence arrest were associated with lowered risks. Significant incident factors included the victim having left for another partner and the perpetrator’s use of a gun. Other significant bivariate-level risks included stalking, forced sex, and abuse during pregnancy. Conclusions. There are identifiable risk factors for intimate partner femicides. PMID:12835191

    There is increasing interest in childhood maltreatment as a potent stimulus that may alter trajectories of brain development, induce epigenetic modifications and enhance risk for medical and psychiatric disorders. Although a number of useful scales exist for retrospective assessment of abuse and neglect they have significant limitations. Moreover, they fail to provide detailed information on timing of exposure, which is critical for delineation of sensitive periods. The Maltreatment and Abuse Chronology of Exposure (MACE) scale was developed in a sample of 1051 participants using item response theory to gauge severity of exposure to ten types of maltreatment (emotional neglect, non-verbal emotional abuse, parental physical maltreatment, parental verbal abuse, peer emotional abuse, peer physical bullying, physical neglect, sexual abuse, witnessing interparental violence and witnessing violence to siblings) during each year of childhood. Items included in the subscales had acceptable psychometric properties based on infit and outfit mean square statistics, and each subscale passed Andersen’s Likelihood ratio test. The MACE provides an overall severity score and multiplicity score (number of types of maltreatment experienced) with excellent test-retest reliability. Each type of maltreatment showed good reliability as did severity of exposure across each year of childhood. MACE Severity correlated 0.738 with Childhood Trauma Questionnaire (CTQ) score and MACE Multiplicity correlated 0.698 with the Adverse Childhood Experiences scale (ACE). However, MACE accounted for 2.00- and 2.07-fold more of the variance, on average, in psychiatric symptom ratings than CTQ or ACE, respectively, based on variance decomposition. Different types of maltreatment had distinct and often unique developmental patterns.

    Using data from four sites in three African countries, this community randomized study examined the association between childhood sexual and/or physical abuse (CSA and/or CPA) and HIV disclosure, HIV-related stigma, stress, and social support among adults with and without a history of abuse. A history of abuse among men was associated with higher levels of adult-reported stress and HIV-related stigma, and with significantly lower rates of HIV test result disclosure to current partners. Women with a history of CSA and/or CPA had significantly higher perceived stigma, discrimination and stress. Although childhood abuse was significantly associated with adult stress and stigmatization, participants with histories of CSA and/or CPA also reported significantly higher perceived social support compared to people without such experiences. These findings may reflect support received in response to disclosure of CSA or CPA or emotional ambivalence in relationships that have been found to be associated with child abuse. We conclude that it is critical for HIV prevention interventions to advocate for the primary prevention of child abuse, for early identification of adolescents and adults who report experiencing childhood abuse, and to address stigma and stress-related attitudinal, behavioral and relationship difficulties experiences as an aftermath of early abuse that increase their risk of HIV.

    ABSTRACT OBJECTIVE To examine the career prevalence of abusive encounters for family physicians in Canada. DESIGN A 7-page cross-sectional mailed survey in English and French. SETTING Canada. PARTICIPANTS A total of 3802 randomly selected practising family physicians who were members of the College of Family Physicians of Canada. MAIN OUTCOME MEASURES Demographic characteristics of survey participants, career prevalence of abusive encounters, and perpetrators of abuse. MAIN FINDINGS Twenty percent (20.4%) of the surveys (n = 774) were returned. Of the respondents, 44% were men and 56% were women. Most were in private practice in urban settings. The average number of years in practice was 15. The career prevalence of abusive encounters was divided into “minor,” “major,” and “severe” incidents. Of all the respondents, 98% had experienced at least 1 incident of minor abuse, 75% had experienced at least 1 incident of major abuse, and 39% had experienced at least 1 incident of severe abuse. Using χ2 analysis, a number of demographic variables were found to be significantly associated with abuse including the physician’s race and sex. Patients were the most common perpetrators of abuse. Ninety percent of family physicians surveyed reported that they had been abused by patients, while 70% reported that they had been abused by family members of patients. CONCLUSION Approximately 2 in 5 family physicians surveyed were subjected to a considerable amount of severe abuse during practice. Abuse in the office setting might have grave consequences for the health and well-being of the victimized physicians and might hinder service retention where the risk of abuse is greatest.

    The purpose of this descriptive study was to: (a) compare the demographics of maltreated youth initially labeled as sexually abused by the Department of Child and Family Services (DCFS) to maltreated youth classified as sexually abused using current and past case records, (b) identify differences in sexual abuse experiences and types of perpetrators between boys and girls, and (c) provide a detailed description of the sexual abuse experiences for boys and girls. Participants were youth ages 9–12 years old with a recent maltreatment allegation. The Maltreatment Case Record Abstraction Instrument (MCRAI) was used to code child welfare records of 303 maltreated youth of whom 60 experienced sexual abuse. Perpetrators were classified by gender into four categories (biological parent, parental figure, relative, and unrelated) and type of abuse was classified into three categories (penetrative, contact without penetration, and non-contact). Using Chi-Square tests, perpetrator categories and sexual abuse types were compared by child gender for significant differences. Only 23 (38.3%) of the 60 sexually abused youth were labeled as sexually abused in the most recent DCFS report when they entered the study. About three-quarters of the sexually abused youth experienced non-penetrative physical contact, 40% experienced penetration, and 15% experienced sexual abuse without physical contact. Most youth (91.7%) were victimized by a male, and 21.7% were abused by a female. Youth experienced a large range of sexual abuse experiences, the details of which may be important for exploration of consequences of childhood sexual abuse. PMID:24095179

    Objectives To assess the feasibility of a novel diagnostic algorithm targeting patients with risk factors for chronic liver disease in a community setting. Design Prospective cross-sectional study. Setting Two primary care practices (adult patient population 10 479) in Nottingham, UK. Participants Adult patients (aged 18 years or over) fulfilling one or more selected risk factors for developing chronic liver disease: (1) hazardous alcohol use, (2) type 2 diabetes or (3) persistently elevated alanine aminotransferase (ALT) liver function enzyme with negative serology. Interventions A serial biomarker algorithm, using a simple blood-based marker (aspartate aminotransferase:ALT ratio for hazardous alcohol users, BARD score for other risk groups) and subsequently liver stiffness measurement using transient elastography (TE). Main outcome measures Diagnosis of clinically significant liver disease (defined as liver stiffness ≥8 kPa); definitive diagnosis of liver cirrhosis. Results We identified 920 patients with the defined risk factors of whom 504 patients agreed to undergo investigation. A normal blood biomarker was found in 62 patients (12.3%) who required no further investigation. Subsequently, 378 patients agreed to undergo TE, of whom 98 (26.8% of valid scans) had elevated liver stiffness. Importantly, 71/98 (72.4%) patients with elevated liver stiffness had normal liver enzymes and would be missed by traditional investigation algorithms. We identified 11 new patients with definite cirrhosis, representing a 140% increase in the number of diagnosed cases in this population. Conclusions A non-invasive liver investigation algorithm based in a community setting is feasible to implement. Targeting risk factors using a non-invasive biomarker approach identified a substantial number of patients with previously undetected cirrhosis.

    Substance abuse is a significant health problem in the adolescent population. Prevention is a formidable challenge, but attempts at discouraging experimentation in early adolescence and the promotion of healthy adult role models may be effective strategies. Questions that may elicit a history suggestive of abuse should be a routine part of the adolescent medical history. Pediatricians should be familiar with the important clinical findings resulting from intoxication with the various substances of abuse and should be able to recognize the "telltale" signs of abuse. Effective management is based on attention to the basics of life support, careful attention to the physical findings, and judicious use of specific therapeutic agents. Above all, a compassionate attitude should prevail if acute-phase recovery and long-term rehabilitation are to be successful. PMID:2870461

    The evaluation of a child presenting with an anogenital complaint or lesion can be challenging for both the clinician and the patient. The doctor met the real possibility that a diagnosis of a condition caused by sexual abuse will affect significantly the child and the family. A misdiagnosis of abuse or failure to recognize a treatable condition can also have detrimental consequences. Most primary care physicians are not trained to recognize the variety of systemic and dermatologic problems that affect the anogenital area. Dermatologists and other specialists often do not appreciate the possibility of sexual abuse. In this article we present a systematic approach to the child with anogenital complaints which may mimic sexual abuse. PMID:19939783

    Identify and analyze cases of child and adolescent abuse and neglect in Curitiba, Brazil. This is an exploratory descriptive study that takes a quantitative approach. Secondary data from the reporting registry of the Network for the Protection of Children and Adolescents at Risk for Violence in Curitiba, Brazil, dating from 2004 to 2009, were analyzed. Variables included the victims' sociodemographic profile, place of notification, type, nature and severity of abuse, information about the author of the aggression or abuse, and physical lesions. The frequency distribution and associations between the variables were analyzed using the Chi-square test at a 5% significance level. The analysis of 19,316 records showed that domestic violence, abuse and neglect directed against children and adolescents were the most frequently recorded situation, with 17,082 cases (88.4%) distributed in the following manner: neglect, with 9742 reports (57.0%); physical violence, with 1341 reports (7.9%); sexual violence, with 796 reports (4.7%); psychological violence, with 574 reports (3.4%); and abandonment, with 190 reports (1.1%). Of the total, 43.9% were considered severe cases. The most affected age group was between 5 and 14 years of age, with balance between genders. In the majority of cases, the mother was registered as the author of the abuse or neglect. Physical sequelae (20.2%) mostly affected the head and upper and lower limbs, with consequent lesions manifesting as bruises, cuts, and fractures. An increase in the visibility of domestic violence and children and adolescents abuse and neglect has been observed in the city during the last few years, suggesting the effectiveness of the reporting strategies proposed by the protection network. It is important to increase social security and public welfare policies to prevent child and adolescent abuse and neglect, focusing on family support. PMID:24661691

    Summary Chronic methamphetamine abuse has devastating effects on the central nervous system. The degree to which addicts will tolerate the dysfunction in the way they think, feel, move, and even look, is a powerful testimony to the addictive properties of this drug. While the mechanisms behind these disorders are complex, at their heart they involve the recurring increase in the concentrations of central monoamines with subsequent dysfunction in dopaminergic neurotransmission. The mainstay of treatment for the problems associated with chronic methamphetamine abuse is abstinence. However, by recognizing the manifestations of chronic abuse, clinicians will be better able to help their patients get treatment for their addiction and to deal with the neurologic complications related to chronic abuse.

    Research has suggested that methamphetamine (METH) use influences orexin regulation. We examined the difference in orexin-A levels between METH abusers and healthy controls. Fasting serum orexin-A levels were measured in 35 participants who used METH in the preceding 3 weeks and 36 healthy controls. We found METH abusers had significantly higher orexin-A levels. No association was observed between orexin-A levels and METH use variables. Our results, consistent with prior preclinical evidence, showed that recent METH exposure is associated with increased orexin-A expression. Further investigation is required to determine whether orexin-A levels normalize after a longer term of abstinence. PMID:27137956

    Research on the impact of maltreatment on children has increased in the last years, as there is a need to design appropriate treatment strategies. Social, cognitive, and emotional areas may be affected in these children. This research is aimed to study the psychological functioning of child victims, particularly in their emotional and cognitive adjustment. Nineteen children (10.3 years old) with case histories of at least 2 years of physical and emotional parental abuse and a group of 26 nonmaltreated children (9.4 years old) matched in socio-economic characteristics and coming from the same community area were compared in depressive symptomatology and attributional style by using the standardized measures from Kovacs' Children's Depression Inventory (CDI) and Kaslow's Children Attributional Style Questionnaire (CASQ). General and detailed statistical analyses on the emotional and cognitive areas assessed showed significant differences between groups. Child victims showed greater feelings of sadness, lower self-esteem and self-worth, and they perceived the aversive events in their lives as unpredictable which generated helplessness. This is a result of their lack of control of those aversive events. Results are contrasted with those obtained by other researchers who used similar methodology and are discussed in terms of the learned helplessness' model proposed and developed by Seligman, Kaslow, Alloy, Peterson, Tanenbaum, and Abramson (1984). Implications for the child abuse victims' emotional and cognitive rehabilitation are also analyzed and discussed. PMID:7850601

    Child sexual abuse (CSA) continues to be a pressing public health concern around the globe. Few existing reports, however, indicate the alarming rate at which the problem is increasing in sub-Saharan Africa. The present study is designed to investigate the psychosocial consequences of sexual abuse among child survivors in Ethiopia who were abused mainly through early marriage, rape, and child prostitution. Data are collected from 318 such CSA survivors-and 318 matched, non-sexually abused, normal controls- using the Children's Impact of Traumatic Events Scale-Revised and the Rosenberg Self-Esteem Scale. The results reveal the CSA survivors to be significantly more symptomatic than the control group: They demonstrated a lower degree of social support, a lower degree of empowerment, as well as a higher degree of guilt and increased likelihood of viewing the world as dangerous. Finally, these CSA survivors show a lower degree of positive self-worth than their non-sexually abused counterparts. These findings have important implications for the formulation of appropriate preventions and interventions to be undertaken by various stakeholders ranging from family to policy makers.

    Childhood abuse increases adult risk for morbidity and mortality. Less clear is how this "toxic" stress becomes embedded to influence health decades later, and whether protective factors guard against these effects. Early biological embedding is hypothesized to occur through programming of the neural circuitry that influences physiological response patterns to subsequent stress, causing wear and tear across multiple regulatory systems. To examine this hypothesis, we related reports of childhood abuse to a comprehensive 18-biomarker measure of multisystem risk and also examined whether presence of a loving parental figure buffers against the impact of childhood abuse on adult risk. A total of 756 subjects (45.8% white, 42.7% male) participated in this ancillary substudy of the Coronary Artery Risk Development in Young Adults Study. Childhood stress was determined by using the Risky Families Questionnaire, a well-validated retrospective self-report scale. Linear regression models adjusting for age, sex, race, parental education, and oral contraceptive use found a significant positive relationship between reports of childhood abuse and multisystem health risks [B (SE) = 0.68 (0.16); P < 0.001]. Inversely, higher amounts of reported parental warmth and affection during childhood was associated with lower multisystem health risks [B (SE) = -0.40 (0.14); P < 0.005]. A significant interaction of abuse and warmth (P < 0.05) was found, such that individuals reporting low levels of love and affection and high levels of abuse in childhood had the highest multisystem risk in adulthood.

    2011-01-01

    This review summarizes findings from human and animal research investigating the influence of progesterone and its metabolites allopreganolone and pregnanolone (progestins) on the effects of cocaine and other drugs of abuse. Since a majority of these studies have used cocaine, this will be the primary focus; however, the influence of progestins on other drugs of abuse will also be discussed. Collectively, findings from these studies support a role for progestins in: 1) attenuating the subjective and physiological effects of cocaine in humans, 2) blocking the reinforcing and other behavioral effects of cocaine in animal models of drug abuse, and 3) influencing behavioral responses to other drugs of abuse such as alcohol and nicotine in animals. Administration of several drugs of abuse in both human and nonhuman animals significantly increased progestin levels, and this is explained in terms of progestins acting as homeostatic regulators that decrease and normalize heightened stress and reward responses which lead to increased drug craving and relapse. The findings discussed here highlight the complexity of progestin-drug interactions, and they suggest a possible use for these agents in understanding the etiology and developing treatments for drug abuse.

  18. Health risk behaviors and medical sequelae of childhood sexual abuse.

    1992-06-01

    The relationship between childhood sexual abuse and subsequent health risk behaviors and medical problems was examined in 511 women who had used a family practice clinic in a rural midwestern community during a 2-year period (1988 and 1989). These women completed a questionnaire that assessed various health risk behaviors--smoking, drinking, drug abuse, number of sexual partners, and age at first intercourse--and a medical symptom checklist that assessed 38 medical problems related to major systems of body function, the somatization scale from the SCL-90, a screen for sexual abuse, and a brief measure of social support. The results indicated that sexually abused women, who represented 22.1% of the sample, reported significantly more medical problems, greater levels of somatization, and more health risk behaviors than did the nonabused women. More severe abuse (for example, penetration or multiple abusers) correlated with more severe problems. Extent of social support correlated inversely with the number of gynecologic problems reported in the sexually abused group. Fewer than 2% of the sexually abused women had discussed the abuse with a physician. To identify and assist victims of sexual abuse, physicians should become experienced with nonthreatening methods of eliciting such information when the medical history is obtained. PMID:1434879

    The present study examined the role of posttraumatic stress symptoms in the relationship between childhood abuse and self-reported psychotic symptoms in severe mental illness. A total of 126 patients diagnosed with major psychiatric conditions with comorbid symptoms of psychosis participated in the present study. The representative psychiatric diagnoses included schizophrenia, bipolar disorder with psychotic features, major depressive disorder with psychotic features, schizoaffective disorder, schizophreniform disorder, and delusional disorder. The Korean Child Trauma Questionnaire measured the type and degree of childhood abuse including emotional, physical, and sexual abuse. Korean version of the Impact of Event Scale-Revised assessed posttraumatic stress symptoms, and PSYC subscale of the PSY-5 Factor Scale of the MMPI-2 was used as a measure of self-reported psychotic symptoms. There was a significant relationship between childhood physical, emotional, sexual abuse and psychotic symptoms. Posttraumatic stress symptoms partially mediated the relationship between childhood abuse and psychotic symptoms. This implies that childhood abuse is significantly associated with the experience of chronic posttraumatic stress symptoms, and that such symptoms in turn increases the likelihood of experiencing psychotic symptoms. The results highlight the need for appropriate assessment and intervention concerning childhood abuse and posttraumatic stress symptoms in severe mental illness. PMID:26144585

    Abuse is a major source of trauma to women, and post-traumatic stress disorder (PTSD) results from exposure to extreme trauma. To describe the relationship between symptoms of PTSD and severity of abuse, an ethnically stratified cohort of 131 abused women in a primary care setting was interviewed. Symptoms of PTSD, both intrusion (i.e., trouble falling asleep, strong waves of feelings about the abuse) and avoidance (i.e., trying not to think or talk about the abuse, staying away from reminders of the abuse), were significantly (p < 0.01) correlated to severity of abuse, regardless of ethnicity. When asked about childhood physical or sexual abuse, women reporting physical abuse had significantly (p < 0.05) higher intrusion scores, whereas those reporting sexual abuse had significantly (p < 0.004) higher avoidance scores. Sixty-five percent of the women reported dreams, flashbacks, or terror attacks and had significantly (p < 0.001) higher mean results on both intrusion and avoidance. The need to offer abused women information about the connection between severity of abuse and symptoms of PTSD is discussed. We recommend that clinicians ask all abused women about dreams, flashbacks, or terror attacks to assess for further symptoms of PTSD. PMID:9356977

    Substance use and a history of childhood sexual abuse have both been identified as risk factors for unprotected sex among women, yet questions remain as to how their combined influence may differentially affect sexual risk behavior. In the current study a Generalized Linear Mixed Model was used to examine the interaction effect between current cocaine and opioid use and a history of childhood sexual abuse (CSA) on number of unprotected sexual occasions (USO) in a sample of 214 sexually active women in outpatient methadone maintenance treatment programs. Results show significant interaction effects between drug use in the past 30 days and CSA on unprotected sexual occasions. These interactions, however, differ depending on type of drug used and CSA status. For women with CSA, an increase in days of cocaine use was significantly associated with an increase in USO, whereas an increase in number of days of opiate use was not significantly associated with an increase in USO. In contrast, for women who did not report CSA, an increase in number of days of cocaine use was associated with a significant decrease in USO and number of days of opiate use was significantly correlated with an increase in USO. Findings indicate that CSA is related to unprotected sexual occasions depending on drug type and severity of use. Women with childhood sexual abuse using cocaine are at particularly high risk for having unprotected sex, which suggests that this group of women should be specifically targeted for HIV prevention interventions.

    SUMMARY Aim The aim of this report is to identify the main oral and dental aspects of physical and sexual abuse and dental neglect in childhood, contributing to the precocious identification and diagnosis in a dental practice. Methods The oral and dental manifestations were divided and classified according to the type of child abuse: physical abuse, sexual abuse, neglect. Physical abuse Several studies in the literature have shown that oral or facial trauma occurs in about 50% of physically abused children; the oral cavity may be a central focus for physical abuse. Oro-facial manifestations of physical abuse include bruising, abrasions or lacerations of tongue, lips, oral mucosa, hard and soft palate, gingiva, alveolar mucosa, frenum; dental fractures, dental dislocations, dental avulsions; maxilla and mandible fractures. Sexual abuse Although the oral cavity is a frequent site of sexual abuse in children, visible oral injuries or infections are rare. Some oral signs may represent significant indications of sexual abuse, as erythema, ulcer, vescicle with purulent drainage or pseudomembranus and condylomatous lesions of lips, tongue, palate and nose-pharynx. Furthermore, if present erythema and petechiae, of unknown etiology, found on soft and hard palates junction or on the floor of the mouth, can be certainly evident proofs of forced oral sex. Dental neglect Oral signs of neglect are easily identifiable and are: poor oral hygiene, halitosis, Early Childhood Caries (ECC), odontogenous infections (recurrent and previous abscesses), periodontal disease, aptha lesions as a consequence of a nutritional deficiency status. Moreover, it is analyzed the assessment of bite marks because often associated with child abuse, the identification and collection of clinical evidence of this type of injury. Conclusion A precocious diagnosis of child abuse, in a dental practice, could considerably contribute in the identification of violence cases and in an early intervention. PMID

    Background There are persistent concerns of long-term effects of stimulant ADHD medication on the development of substance abuse. Methods Using Swedish national registers, we studied all individuals born 1960–1998 and diagnosed with ADHD (26,249 men and 12,504 women). We investigated the association between stimulant ADHD medication in 2006 and substance abuse during 2009. Substance abuse was indexed by substance-related death, crime, or hospital visits. Results ADHD medication was not associated with increased rate of substance abuse. Actually, the rate during 2009 was 31% lower among those prescribed ADHD medication in 2006, even after controlling for medication in 2009 and other covariates (hazard ratio: 0.69; 95% confidence interval: 0.57–0.84). Also the longer duration of medication, the lower the rate of substance abuse. Similar risk reductions were suggested among children and when investigating the association between stimulant ADHD medication and concomitant short-term abuse. Conclusions We found no indication of increased risks of substance abuse among individuals prescribed stimulant ADHD medication; if anything, the data suggested a long-term protective effect on substance abuse. Although stimulant ADHD medication does not seem to increase the risk for substance abuse, clinicians should remain alert to the potential problem of stimulant misuse and diversion in ADHD patients.

    This article delineates the current fiscal management and reimbursement for child abuse examinations. These financial issues are high priority for child abuse programs because most programs lack the revenues to meet the demands for service, education, advocacy and research. Programs may share medical protocols and standards but have yet to share management solutions. The authors present the administrative details of 75 child abuse evaluation programs and highlight innovative approaches to increase funding and stabilize the funding for the programs. They present information on billing, contracts, costs of care, and state-based initiatives that can be reproduced by other programs and states. PMID:16595851

    The objective of this article is to compare male- and female-perpetrated sexual abuse in terms of victim and abuser characteristics, type of abuse, family structure, and worker information. Bivariate tests of significance were performed on the 1998 Canadian Incidence Study of Reported Child Abuse and Neglect, which included 308 male and 37 female abusers. Results show a prevalence rate of 10.7% for female-perpetrated sexual abuse. Girls were more likely to be victimized for both male- and female-perpetrated sexual violence and females tended to abuse younger children. The majority of children came from families with lower socioeconomic status although one in five victims of female-perpetrated sexual abuse came from middle-class homes. Referrals to child welfare agencies were more likely to be made by nonprofessionals when females abused. PMID:18701747

    This study examined self-reported sexually abusive experiences in childhood and adulthood as correlates of current drug use, alcohol abuse, and depression and posttraumatic stress disorder (PTSD) symptoms. Participants were 204 Latina women 18-34 years old. Results indicated significant relationships between history of sexual abuse (regardless of age of occurrence), depression symptoms, PTSD symptoms, alcohol abuse, and drug use. When examined separately, childhood sexual abuse was associated with symptoms of depression, PTSD, and substance use but not alcohol abuse behaviors. Experiencing sexual abuse in adulthood was associated with symptoms of depression, alcohol abuse behaviors, and substance use but not PTSD symptoms. Structural equation modeling showed that substance use partially mediated the relationship between sexual abuse and mental health outcomes. These findings suggest mental health and substance use services should incorporate treatment for trauma, which may be the root of comorbid mental health and substance use issues. PMID:25635897

    The Centers for Disease Control and Prevention (CDC) has published significant data trends related to substance abuse involving opioid pain relievers (OPR), benzodiazepines and alcohol in the United States. The CDC describes opioid misuse and abuse as an epidemic, with the use of OPR surpassing that of illicit drugs. Alcohol has also been a persistent problem and is associated with a number of emergency department visits and deaths independent of other substances. The use of these drugs in combination creates an additive effect with increased central nervous system suppression and a heightened risk of an overdose. We present a summary of the findings from the Morbidity and Mortality Weekly Report (MMWR) with commentary on strategies to combat prescription drug and alcohol abuse. PMID:25671013

    A free videotape subscription series was utilized to increase the knowledge of general physicians in clinical practice about the medical evaluation of sexually abused children. Of the 65 physicians who requested the first tape, 39 (60%) completed it. Fourteen of the 39 physicians who completed the first tape (36%) completed the 5-tape series. Completion data suggested that series completion was unrelated to prior knowledge, years since training or number of sexual abuse examinations performed in the previous year. Evaluative comments suggested that quality of the tapes was not a factor in completion rate. On tests of immediate retention, the average posttest percent correct was significantly higher than on the pretest. In a 3-year follow-up of the 14 physicians who completed the series, 10 reported that they were still performing sexual abuse examinations. PMID:15353378

    This study of 329 substance abuse treatment staff assessed how recovery status, in combination with other variables, influences beliefs about the causes and treatment of substance abuse. About 15% (n = 47) of participants were "in recovery" from substance abuse problems; these staff members were not significantly different than nonrecovering staff members on education, age, race/ethnicity, years of clinical experience, or amount of client contact. When examined in a multiple regression equation that also included age, education, and treatment program goals and activities, staff members' recovery status was not associated with endorsement of disease and psychosocial models of substance abuse. However, being in recovery was associated with endorsing an eclectic approach to substance abuse treatment. The importance of recognizing the diversity of beliefs about substance abuse among recovering staff and of acknowledging that multiple influences affect all staff members viewpoints on treatment is discussed.

    Previous studies of adult females reporting incestuous sexual abuse in childhood, using the Apperceptive Personality Test and Draw-a-Person Questionnaire, indicated abusees attributed more negative traits to their characters than did controls. No differences were found by type of abuse or relation to the abuser. In these studies abusees and controls were obtained from different sources, although matched on several characteristics. The present study compared 79 incestuous abusees to 79 matched controls all drawn from the same subject pool. Multivariate analysis of variance identified significant differences between the groups. In contrast with earlier studies questionnaire scores distinguished rape victims from those abused without rape and distinguished those abused by older relatives from those abused by peers in two additional multivariate analyses of variance.

    Prior research has shown that people with intellectual disabilities (ID) are more likely to experience child abuse as well as other forms of traumatic or negative events later in life compared to the general population. Little is known however, about the association of these experiences with adult mental health in intellectually disabled individuals. The present study aimed to assess whether child abuse in families and institutions as well as other types of adverse life events, were associated with current posttraumatic stress disorder (PTSD) and depression symptoms in individuals with ID. We conducted clinical interviews which included standardized self-report measures for childhood abuse, PTSD, and depression in an unselected sample of 56 persons with a medical diagnosis of ID who were attending a specialized welfare center. The frequency of traumatic experiences was very high, with physical and emotional child abuse being the most common trauma types. 87% of the persons reported at least one aversive experience on the family violence spectrum, and 50% of the sample reported a violent physical attack later in adulthood. 25% were diagnosed with PTSD and almost 27% had a critical score on the depression scale. Physical and emotional child abuse was positively correlated with the amount of institutional violence and the number of general traumatic events, whereas childhood sexual abuse was related to the experience of intimate partner violence in adult life. A linear regression model revealed child abuse in the family to be the only significant independent predictor of PTSD symptom severity. The current findings underscore the central role of child maltreatment in the increased risk of further victimization and in the development of mental health problems in adulthood in intellectually disabled individuals. Our data have important clinical implications and demonstrate the need for targeted prevention and intervention programs that are tailored to the specific needs

    To assess the effects of chronic cocaine intoxication on dopamine receptors in human subjects, the authors evaluated ({sup 18}F)N-methylspiroperidol binding using positron emission tomography in 10 cocaine abusers and 10 normal control subjects. Cocaine abusers who had been detoxified for 1 week or less showed significantly lower values for uptake of ({sup 18}F)N-methylspiroperidol in striatum than the normal subjects, whereas the cocaine abusers who had been detoxified for 1 month showed values comparable to those obtained from normal subjects. The authors conclude that postsynaptic dopamine receptor availability decreases with chronic cocaine abuse but may recover after a drug-free interval.

    Children who have suffered early abuse or neglect may later present with significant behavior problems including emotional instability, depression, and a tendency to be aggressive or violent with others. Troublesome behaviors may persist long after the abusive or neglectful environment has changed or the child has been in foster care placement. Neurobiological research has shown that early abuse results in an altered physiological response to stressful stimuli, a response that deleteriously affects the child's subsequent socialization. Pediatricians can assist caregivers by helping them recognize the abused or neglected child's altered responses, formulate more effective coping strategies, and mobilize available community resources.

    Childhood abuse and neglect (child maltreatment) represent a common and significant public health burden. The consequences of maltreatment can be seen immediately, in the short term and in the long term. Determination of the exact prevalence of childhood maltreatment is difficult, as many cases go unreported; however in reported cases there is an estimated $124 billion annual burden on the US health-care system. The evaluation of potential maltreatment is difficult as many of the initial symptoms are subtle and can be explained with alternative illnesses or injuries. Potential immediate and short-term effects include brain injury, shaken baby syndrome and behavioral regression. The potential long-term sequelae of child maltreatment are explored in detail here and include increased risks of the development of mental health disorders, substance use disorders and chronic physical complaints during development and adulthood. Lastly, the review provides an overview of current treatment approaches for victims of childhood maltreatment. PMID:23307564

    Cocaine abuse represents a worldwide significant forensic issue as it is becoming widely recognized as one of the most dangerous illicit drugs in common use today. Besides cardiovascular complications, psychiatric and neurologic symptoms are the most common manifestations of cocaine toxicity. The latter include seizures, movement disorders and cerebrovascular complications. In chronic cocaine abusers morphological, physiological, and neurochemical abnormalities have been demonstrated by using neuroradiological techniques such as computed tomography, magnetic resonance imaging, positron emission tomography or single photon emission computed tomography. The spectrum of neuropathologic changes encountered in the brains of cocaine abusers is broad, but the major findings consist of ischemic and hemorrhagic stroke, subarachnoid and intracerebral hemorrhages and cerebral ischemia. Especially persons with underlying arteriovenous malformation or aneurysm are at risk for such events. Except for a few instances of vasculitis, the etiology of cocaine-related cerebrovascular accidents is still unclear. Besides pharmacologically-induced vasospasm, impaired hemostasis and platelet function and decreased cerebral blood flow have been proposed. At the cellular level, abnormalities in the expression of transcription factors and changes of brain neurotransmitter systems have been reported. PMID:12935600

    Chronically SIVagm-infected African green monkeys (AGMs) have a remarkably stable non-pathogenic disease course, with levels of immune activation in chronic SIVagm infection similar to those observed in uninfected monkeys and stable viral loads (VLs) for long periods of time. In vivo administration of lipopolysaccharide (LPS) or an IL-2/diphtheria toxin fusion protein (Ontak) to chronically SIVagm-infected AGMs triggered increases in immune activation and subsequently of viral replication and depletion of intestinal CD4{sup +} T cells. Our study indicates that circulating microbial products can increase viral replication by inducing immune activation and increasing the number of viral target cells, thus demonstrating that immune activation and T cell prolifeation are key factors in AIDS pathogenesis.

  7. Sexual abuse of children and adolescents.

    PubMed

    Sugar, M

    1983-01-01

    Parents, relatives, and friends may inflict their passions on children of the same or opposite sex. This is often initiated by sleeping together. Sexual abuse contributes to and causes emotional trauma, although the child's turmoil, confusion, wish for acceptance, and anxiety may be overlooked by the parent and professional. Mutual silence aided by threats adds to the anxiety. Despite the notion that reports of parental sexual exploitation of their children are usually fantasies, there appear to be increasing data that incest and sexual abuse are frequent traumata. At present, there is increased risk of lowering the incest barrier because of increased rates of divorce and step- or surrogate parenthood, since they provide additional potential for being sexually and emotionally traumatized. Sexual abuse seems to be part of a constellation involving neglect and a pathological symbiosis. That sexual abuse is emotionally traumatic is apparent, but it needs emphasizing. Children's defensive reactions may cloud this, and it may be years before such incidents are connected to symptomatic behavior, even when the child is in intensive therapy. In the reported cases, there appears to be a pattern of reactions and defenses related to the traumata that are embedded in imprinting and identification with the aggressor. This leads to sexual abuse being a legacy passed on to the next generation of victims, as the victim becomes the molester through identification. Adolescent self-destructive behavior may stem from guilt about sexually abusing younger children. Therapists may be better able to understand and deal with some of their patients' symptoms if sexual abuse is considered as a possible factor in one or both directions. PMID:6677153

    Lignin is a component of the cell wall that is essential for growth, development, structure and pathogen resistance in plants, but high lignin is an obstacle to the conversion of cellulose to ethanol for biofuel. Genetically modifying lignin and cellulose contents can be a good approach to overcoming that obstacle. Alfalfa (Medicago sativa L.) is rich in lignocellulose biomass and used as a model plant for the genetic modification of lignin in this study. Two key enzymes in the lignin biosynthesis pathway-hydroxycinnamoyl -CoA:shikimate hydroxycinnamoyl transferase (HCT) and coumarate 3-hydroxylase (C3H)-were co-downregulated. Compared to wild-type plants, the lignin content in the modified strain was reduced by 38%, cellulose was increased by 86.1%, enzyme saccharification efficiency was increased by 10.9%, and cell wall digestibility was increased by 13.0%. The modified alfalfa exhibited a dwarf phenotype, but normal above ground biomass. This approach provides a new strategy for reducing lignin and increasing cellulose contents and creates a new genetically modified crop with enhanced value for biofuel. PMID:26398807

    Institutionalized elderly who are frail and dependent are vulnerable to be abused by overwhelmed caregivers especially caregiver psychological abusive behavior is a growing but hidden problem with few evidence-based interventions. The purpose of this study was to examine the effectiveness of an educational support group in alleviating caregiver's psychological abusive behavior, reducing work stress and promoting knowledge of geriatric care-giving among a group of caregivers. A quasi-experimental design using a case control pre-post test approach was conducted. A total of 100 participants completed the study with 50 caregivers in each group. The research instruments included the Caregiver Psychological Elder Abuse Behavior Scale (CPEAB), the Work Stressors Inventory (WSI), and the Knowledge of Gerontology Nursing Scale (KGNS). The results showed that the intervention had significant effects in alleviating caregiver psychological abuse behavior and increasing care-giving knowledge in the experimental group (p = .048; .018). However, the intervention had no measurable effect on work stress (p = .66). Findings have important implications for education and programming for facility administers and long-term care policy makers when planning quality improvement for elderly care. PMID:18516696

    Three cases of prolonged abuse of Do-Do tablets, an over-the-counter remedy for "coughs, wheezing and breathlessness", are reported. They have an amphetamine-like action and were used as easily obtained amphetamine substitutes, in one case to relieve social anxiety. Withdrawal symptoms similar to those following cessation of amphetamines occurred in two cases. Do-Do tablets are CNS stimulants and their abuse may be accounted for by the fact that they perhaps affect amine neurotransmitters. PMID:2224380

Anti-addiction vaccines to elicit antibodies that block the pharmacological effects of drugs have great potential for treating drug abuse. We review the status for two vaccines that are undergoing clinical trials (cocaine and nicotine) and two that are still in pre-clinical development (methamphetamine and heroin). We also outline the challenges and ethical concerns for anti-addiction vaccine development and their use as future therapeutics. PMID:22130115

  13. Does the use of salmon frames as bait for lobster/crab creel fishing significantly increase the risk of disease in farmed salmon in Scotland?

    PubMed

    Murray, Alexander G

    2015-07-01

    Salmon farming is an important economic activity, and employer, particularly for remoter areas of Scotland; crustacean fisheries are also significant small businesses in these areas. Salmon frames (the head and spine that remain after evisceration and filleting) are sometimes used to bait the creel pots used to catch lobsters and crabs. These frames may contain pathogens that could potentially be spread to salmon farms in the vicinity of creel fisheries. Therefore, an analysis has been carried out for key pathogens of farmed salmon to assess the risks associated with this process. Infection of farms via creel bait requires that: (1) pathogens are present in salmon at harvest; (2) they are not removed from the salmon that used for bait during processing; (3) they transmit from creel pot baits to salmon farms. This last step is critical and leads to most of the uncertainty in results. Risk were assessed for 7 viruses, 3 bacteria, and 3 eukaryotic parasites of importance to salmon farming. A potentially significant risk was identified in association with disease control programmes if fish were filleted at a secondary processor; such a situation should arise only rarely. A very low risk, per event, was identified from imports, however, because of large numbers of Norwegian imports processed in the UK this risk is always present. Risks were at worst of low (disease control) or very low (imports) probability and are significant only because of the magnitude of consequences. PMID:25980750

    It is estimated that the percentage of students using illicit substances by sixth grade has tripled over the last decade not only in developed countries but in developing countries as well probably due to the transition to a more Western society. Although much has been done to understand the mechanisms underlying substance abuse, few studies have been conducted with minority ethnic and religious groups such as Middle Eastern Youth. The primary goal of this study was to determine whether there are differences in factors contributing to substance abuse in adolescents from Lebanon versus the U.S.A. and to decipher the role of spirituality, religion, and culture among other factors that may influence substance abuse. A correlational cross-sectional design was used with adolescents living in two different countries: Los Angeles, California and Beirut, Lebanon. Muslim adolescents had significantly less rates of alcohol and substance use than Christians in both Lebanon and Los Angeles. More years lived in the U.S.A. increases the likelihood of abuse for both Muslims and Christians. Attachment to God and family was negatively associated with substance abuse. These results among others facilitate a better understanding of the influence of culture, religion, family and personal factors on substance abuse. Culturally sensitive interventions could benefit from the findings of this pilot study. PMID:23526183

    Background Accumulating evidence indicates that schizophrenia is associated with brain immune activation. While a number of reports suggest increased cytokine levels in patients with schizophrenia, many of these studies have been limited by their focus on peripheral cytokines or confounded by various antipsychotic treatments. Here, well-characterized patients with schizophrenia, all receiving olanzapine treatment, and healthy volunteers were analyzed with regard to cerebrospinal fluid (CSF) levels of cytokines. We correlated the CSF cytokine levels to previously analyzed metabolites of the kynurenine (KYN) pathway. Methods We analyzed the CSF from patients and controls using electrochemiluminescence detection with regard to cytokines. Cell culture media from human cortical astrocytes were analyzed for KYN and kynurenic acid (KYNA) using high-pressure liquid chromatography or liquid chromatography/mass spectrometry. Results We included 23 patients and 37 controls in our study. Patients with schizophrenia had increased CSF levels of interleukin (IL)-6 compared with healthy volunteers. In patients, we also observed a positive correlation between IL-6 and the tryptophan:KYNA ratio, indicating that IL-6 activates the KYN pathway. In line with this, application of IL-6 to cultured human astrocytes increased cell medium concentration of KYNA. Limitations The CSF samples had been frozen and thawed twice before analysis of cytokines. Median age differed between patients and controls. When appropriate, all present analyses were adjusted for age. Conclusion We have shown that IL-6, KYN and KYNA are elevated in patients with chronic schizophrenia, strengthening the idea of brain immune activation in patients with this disease. Our concurrent cell culture and clinical findings suggest that IL-6 induces the KYN pathway, leading to increased production of the N-methyl-d-aspartate receptor antagonist KYNA in patients with schizophrenia.

    Maize seed storage proteins are a major source of human and livestock consumption. However, these proteins have poor nutritional value, because they are deficient in lysine and tryptophan. Much research has been done to elevate the lysine content by reducing zein content or regulating the activities of key enzymes in lysine metabolism. Using the naturally lysine-rich protein genes, sb401 and SBgLR, from potato, we previously increased the lysine and protein contents of maize seeds. Here, we examined another natural lysine-rich protein gene, GhLRP, from cotton, which increased the lysine content of transgenic maize seeds at levels varying from 16.2% to 65.0% relative to the wild-type. The total protein content was not distinctly different, except in the six transgenic lines. The lipid and starch levels did not differ substantially in Gossypium hirsutum L. lysine-rich protein (GhLRP) transgenic kernels when compared to wild-type. The agronomic characteristics of all the transgenic maize were also normal. GhLRP is a high-lysine protein candidate gene for increasing the lysine content of maize. This study provided a valuable model system for improving maize lysine content. PMID:24681583

    Oligonucleotides can be used to direct the alteration of single nucleotides in chromosomal genes in yeast. Rad51 protein appears to play a central role in catalyzing the reaction, most likely through its DNA pairing function. Here, we re-engineer the RAD51 gene in order to produce proteins bearing altered levels of known activities. Overexpression of wild-type ScRAD51 elevates the correction of an integrated, mutant hygromycin resistance gene ∼3-fold. Overexpression of an altered RAD51 gene, which encodes a protein that has a higher affinity for ScRad54, enhances the targeting frequency nearly 100-fold. Another mutation which increases the affinity of Rad51 for DNA was also found to increase gene repair when overexpressed in the cell. Other mutations in the Rad51 protein, such as one that reduces interaction with Rad52, has little or no effect on the frequency of gene repair. These data provide the first evidence that the Rad51 protein can be modified so as to increase the frequency of gene repair in yeast. PMID:15087488

    In order to assess patterns of heat sensitivity thresholds in patients with diabetes mellitus, the Akabane test was carried out on patients with insulin dependent diabetes mellitus (IDDM) (250 men and 309 women) and patients with noninsulin dependent diabetes mellitus (NIDDM) (158 men and 227 women). For comparison, a group of healthy subjects made up of 116 men and 277 women was also used. As soon as we revealed the influence of factors of pathology with a high significance level and gender and the interaction "gender*pathology", all the results are described separately for groups of men and women and for groups with IDDM and NIDDM. Simple effects of paired comparisons between healthy subjects, IDDM and NIDDM in groups of men and women, as well as comparisons between the profiles of men and women with IDDM and NIDDM showed significant differences between ACs in healthy subjects and those with each type of diabetes. The most significant differences are seen in the AC connected with the digestive system (SP pancreas channel), LR (liver channel), ST (stomach channel), GB (gall bladder channel). Thus, we revealed characteristic pattern of acupuncture channels (AC) lesions inherent to diabetes pathology, i.e. most vulnerable in diabetes ACs, being compromised in dependence from such factors, as type of diabetes, hyper or hypoglycemia, and from gender. The main value of the method lies in the fact that we observe the entire food chain from food ingestion to the utilization of carbohydrates with the opportunity to assess the activity of each organ and its regulatory contribution. On the basis of the body's response, an individual selection of medicines can be made, and by evaluating the individual biorhythms it is possible to determine the optimal time of administration.

    Discusses factors inhibiting open talk around a client's history of abuse including gender, age and diagnosis. * Evaluates the helpfulness of a training course designed to reduce and overcome these factors. * Aim of the evaluation is to help replicate the training nationally, following the positive impact found. Abstract Despite the high prevalence of sexual abuse among users of mental health services, it appears that mental health professionals are frequently unaware of clients' abuse histories. In order to address this, a Mental Health Trusts Collaboration Project of nine trusts was formed, which piloted delivering the Department of Health's Victims of Violence & Abuse Prevention Programme one-day education and training course regarding enquiring about histories of sexual abuse to various mental health practitioners. This hoped to educate practitioners in factors associated with victims and offenders, improve confidence and competence in asking about client's history of abuse and to increase awareness of the importance of asking. The purpose of this paper is to describe the impact of this course on mental health professionals' practice and attitudes in one of these nine trusts. It was found that since the delivery of the course, 44% (n= x) of professionals had been asking about abuse in 75-100% of cases. Gender, age and diagnosis of both the service users and the practitioners were all identified as factors potentially affecting practitioners' willingness to ask about abuse. Most importantly, 93% (n= x) of participants were found to feel they have the skills and knowledge to enquire about abuse and respond to disclosure in the appropriate way and 77% (n= x) of participants felt that this training had changed their clinical practice. The aim of this evaluation is to prove the effectiveness of the Department of Health's education and training course, which will help towards replicating the project nationally. PMID:20100302

    2010-03-01

    Carisoprodol (N-isopropyl-2 methyl-2-propyl-1,3-propanediol dicarbamate; N-isopropylmeprobamate) is a centrally acting skeletal muscle relaxant whose primary active metabolite is meprobamate, a substance with well established abuse potential similar to that of benzodiazepines. A number of reports show that carisoprodol has been abused for its sedative and relaxant effects, to augment or alter the effects of other drugs, and by the intentional combination of carisoprodol and other noncontrolled medications because of the relative ease (as compared to controlled substances) of obtaining prescriptions. The diversion and abuse of carisoprodol and its adverse health effects appear to have dramatically increased over the last several years. Clinicians have begun to see a withdrawal syndrome consisting of insomnia, vomiting, tremors, muscle twitching, anxiety, and ataxia in patients who abruptly cease intake of large doses of carisoprodol. Hallucinations and delusions may also occur. The withdrawal symptoms are very similar to those previously described for meprobamate withdrawal, suggesting that what may actually be occurring is withdrawal from meprobamate accumulated as a result of intake of excessive amounts of carisoprodol. However carisoprodol itself is capable of modulating GABA(A) function, and this may contribute both to the drugs abuse potential and to the occurrence of a withdrawal syndrome with abrupt cessation of intake. Carisoprodol has been classified as a controlled substance in several states in the US and restrictions on the use of the drug have been imposed in some European countries. Carisoprodol is metabolized to a controlled substance, has clear evidence of abuse potential and increasing incidence of abuse, and has shown evidence of a withdrawal syndrome with abrupt cessation from intake. This article will discuss the abuse potential of carisoprodol and the associated withdrawal syndrome, and consider implications for future use of the drug. PMID

    China’s forests are characterized by young age, low carbon (C) density and a large plantation area, implying a high potential for increasing C sinks in the future. Using data of provincial forest area and biomass C density from China’s forest inventories between 1994 and 2008 and the planned forest coverage of the country by 2050, we developed a stage-classified matrix model to predict biomass C stocks of China’s forests from 2005 to 2050. The results showed that total forest biomass C stock would increase from 6.43 Pg C (1 Pg = 1015 g) in 2005 to 9.97 Pg C (95% confidence interval: 8.98 ~ 11.07 Pg C) in 2050, with an overall net C gain of 78.8 Tg C yr−1 (56.7 ~ 103.3 Tg C yr−1; 1 Tg = 1012 g). Our findings suggest that China’s forests will be a large and persistent biomass C sink through 2050. PMID:26110831

    Objectives The aims of this study were to examine the prevalence of child abuse exposure among Thai people in a suburban community and to describe the association of abuse experiences with common mental disorders (CMD), alcohol use disorders and substance use. Methods A population-based cross-sectional survey was conducted in Northern Bangkok on a representative sample of 202 young residents, aged 16–25 years. Results Thirty eight percent of the respondents reported experiencing some form of abuse during childhood, with 5.8% having been subjected to sexual penetration, 11.7% having been physically abused and 31.8% emotionally abused. A graded relationship was found between the extent of exposure to abuse during childhood and mental problems. After controlling for potential confounders, CMD remained significantly associated with emotional abuse, and alcohol use disorders remained associated with sexual abuse. Strong but non-significant trends were present for associations between CMD and sexual abuse and all forms of abuse with substance use. Conclusion Child abuse experiences were common among the respondents. Childhood abuse, particularly sexual abuse, has a potentially devastating impact on adult mental health. PMID:16328752

    The existing data suggest that individuals experiencing intra-familial abuse are affected more significantly than those experiencing extra-familial abuse. This study aims to identify possible differences between these types of abuse. A retrospective study was performed based on medico-legal reports related to children suspected of being sexually abused (n=1054). The results revealed that 40.2% of the suspected abuses were intra-familial and were significantly different than extra-familial cases with respect to the following: (a) the complainants were younger; (b) their relationship to the alleged abuser was closer; (c) the alleged abusers had higher rates of previous sexual abuse; (d) the suspected abuses were less intrusive physically; (e) there was less physical but more psychological violence; (f) the delay between the last abuse and the medico-legal examination was greater; and (g) there were fewer physical signs and DNA evidence (none in the great majority of cases). These results highlight aspects of intra-familial abuse that have been identified as factors influencing the severity of its consequences - physically, these instances of abuse were less intrusive but psychologically they were more intrusive than extra-familial abuse. This justifies the use of different strategies in the diagnosis and support for victims within the family. PMID:19782315

    The aim of this study was to evaluate the frequency of humoral endocrine organ-specific autoimmunity in 47,XXY Klinefelter's syndrome (KS) by investigating the autoantibody profile specific to type 1 diabetes (T1DM), Addison's disease (AD), Hashimoto thyroiditis (HT), and autoimmune chronic atrophic gastritis (AG). Sixty-one adult Caucasian 47,XXY KS patients were tested for autoantibodies specific to T1DM (Insulin Abs, GAD Abs, IA-2 Abs, Znt8 Abs), HT (TPO Abs), AD (21-OH Abs), and AG (APC Abs). Thirty-five of these patients were not undergoing testosterone replacement therapy TRT (Group 1) and the remaining 26 patients started TRT before the beginning of the study (Group 2). KS autoantibody frequencies were compared to those found in 122 control men. Six of 61 KS patients (9.8 %) were positive for at least one endocrine autoantibody, compared to 6.5 % of controls. Interestingly, KS endocrine immunoreactivity was directed primarily against diabetes-specific autoantigens (8.2 %), with a significantly higher frequency than in controls (p = 0.016). Two KS patients (3.3 %) were TPO Ab positive, whereas no patients were positive for AD- and AG-related autoantigens. The autoantibody endocrine profile of untreated and treated KS patients was not significantly different. Our findings demonstrate for the first time that endocrine humoral immunoreactivity is not rare in KS patients and that it is more frequently directed against type 1 diabetes-related autoantigens, thus suggesting the importance of screening for organ-specific autoimmunity in clinical practice. Follow-up studies are needed to establish if autoantibody-positive KS patients will develop clinical T1DM. PMID:25935328

    The blood plasma of healthy people contains cell-fee (circulating) DNA (cfDNA). Apoptotic cells are the main source of the cfDNA. The cfDNA concentration increases in case of the organism's cell death rate increase, for example in case of exposure to high-dose ionizing radiation (IR). The objects of the present research are the blood plasma and blood lymphocytes of people, who contacted occupationally with the sources of external gamma/neutron radiation or internal β-radiation of tritium N = 176). As the controls (references), blood samples of people, who had never been occupationally subjected to the IR sources, were used (N = 109). With respect to the plasma samples of each donor there were defined: the cfDNA concentration (the cfDNA index), DNase1 activity (the DNase1 index) and titre of antibodies to DNA (the Ab DNA index). The general DNA damage in the cells was defined (using the Comet assay, the tail moment (TM) index). A chronic effect of the low-dose ionizing radiation on a human being is accompanied by the enhancement of the DNA damage in lymphocytes along with a considerable cfDNA content reduction, while the DNase1 content and concentration of antibodies to DNA (Ab DNA) increase. All the aforementioned changes were also observed in people, who had not worked with the IR sources for more than a year. The ratio cfDNA/(DNase1×Ab DNA × TM) is proposed to be used as a marker of the chronic exposure of a person to the external low-dose IR. It was formulated the assumption that the joint analysis of the cfDNA, DNase1, Ab DNA and TM values may provide the information about the human organism's cell resistivity to chronic exposure to the low-dose IR and about the development of the adaptive response in the organism that is aimed, firstly, at the effective cfDNA elimination from the blood circulation, and, secondly - at survival of the cells, including the cells with the damaged DNA.

The current cross-sectional study employed multiple regression techniques to assess the effects of childhood trauma on adulthood depression and emotion dysregulation in a large sample of mostly low-income African Americans recruited in an urban hospital. Bootstrap analyses were used to test emotion dysregulation as a potential mediator between emotional abuse in childhood and current depression. Childhood emotional abuse significantly predicted depressive symptoms even when accounting for all other childhood trauma types, and we found support for a complementary mediation of this relationship by emotion dysregulation. Our findings highlight the importance of emotion dysregulation and childhood emotional abuse in relation to adult depression. Moving forward, clinicians should consider the particular importance of emotional abuse in the development of depression, and future research should seek to identify mechanisms through which emotional abuse increases risk for depression and emotion dysregulation.
