Preventing child abuse and neglect with a program of nurse home visitation: the limiting effects of domestic violence.

CONTEXT: Home visitation to families with young children has been promoted as an effective way to prevent child maltreatment, but few studies have examined the conditions under which such programs meet this goal. OBJECTIVE: To investigate whether the presence of domestic violence limits the effects of nurse home visitation interventions in reducing substantiated reports of child abuse and neglect. DESIGN: Fifteen-year follow-up study of a randomized trial. SETTING: Semirural community in upstate New York. PARTICIPANTS: Of 400 socially disadvantaged pregnant women with no previous live births enrolled consecutively between April 1978 and September 1980, 324 mothers and their children participated in the follow-up study. INTERVENTIONS: Families were randomly assigned to receive routine perinatal care (control group; n = 184 participated in follow-up), routine care plus nurse home visits during pregnancy only (n = 100), or routine care plus nurse home visits during pregnancy and through the child's second birthday (n = 116). MAIN OUTCOME MEASURES: Number of substantiated reports over the entire 15-year period involving the study child as subject regardless of the identity of the perpetrator or involving the mother as perpetrator regardless of the identity of the child abstracted from state records and analyzed by treatment group and level of domestic violence in the home as measured by the Conflict Tactics Scale. RESULTS: Families receiving home visitation during pregnancy and infancy had significantly fewer child maltreatment reports involving the mother as perpetrator (P =. 01) or the study child as subject (P =.04) than families not receiving home visitation. The number of maltreatment reports for mothers who received home visitation during pregnancy only was not different from the control group. For mothers who received visits through the child's second birthday, the treatment effect decreased as the level of domestic violence increased. Of women who reported 28 or fewer incidents of domestic violence (79% of sample), home-visited mothers had significantly fewer child maltreatment reports during the 15-year period than mothers not receiving the longer-term intervention (P =.01). However, this intervention did not significantly reduce child maltreatment among mothers reporting more than 28 incidents of domestic violence (21% of sample). CONCLUSIONS: The presence of domestic violence may limit the effectiveness of interventions to reduce incidence of child abuse and neglect. JAMA. 2000;284:1385-1391.

Motoneurons of M. semitendinosus in domestic and wild pigs. A horseradish peroxidase and cord-survey study.

In domestic and wild pigs motor nuclei of the M. semitendinosus were labelled by retrograde transport of horseradish peroxidase (HRP) from muscle to spinal cord. Further motoneurons in the lumbosacral cord were stained with Luxol-fast-blue and cresyl violet. Motoneurons innervating M. semitendinosus were present in the ventral horns of the last (6th) lumbal and the first sacral cord segments. They were localized within two motor columns lying parallel to each other in the medial and lateroventral position. Both parts of the semitendinosus motor nuclei showed a spindle-like shape with both cranial and caudal enlargements. Localization, extent, and shape of the semitendinosus motor nuclei were similar in domestic and wild pigs. The average motoneuron diameter was larger in domestic than in wild pigs. The lumbosacral cord of the wild pig was thicker than that of the domestic pig. It is suggested that the size of alpha-motoneurons has increased as a result of selective breeding after domestication. This process might correlate with a higher incidence of myopathies in domestic pigs.

The systematics of nematodes that cause ostertagiasis in domestic and wild ruminants in North America: an update and a key to species.

Studies of medium stomach worms (Subfamily Ostertagiinae) of domestic and wild ruminants in North America have refined our understanding of the systematics, host distribution and biogeography of these nematodes. Strong support for recognition of monophyly for the Ostertagiinae has resulted from preliminary phylogenetic analyses of morphological characters among these and other trichostrongylids. Evaluation of morphological and biochemical characters in our laboratory and elsewhere has not refuted the polymorphism hypothesis where paired major and minor morphotypes are postulated to represent polymorphic species within the genera Ostertagia (Ostertagia ostertagi/Ostertagia lyrata; Ostertagia leptospicularis/Ostertagia kolchida; Ostertagia gruehneri/Ostertagia arctica; Ostertagia mossi/Ostertagia dikmansi), Teladorsagia (Teladorsagia circumcincta/Teladorsagia trifurcata (= Teladorsagia davtiani), and Marshallagia (Marshallagia marshalli/Marshallagia occidentalis). The minor morphotype of Ostertagia bisonis, recognized in Eurasia (considered to be Teladorsagia kazakhstanica), has yet to be discovered in North America. The taxonomy of these species has remained stable since an earlier overview of Ostertagia spp. and Teladorsagia spp. in North American domestic stock at the 1986 Ostertagia Workshop. Investigations since 1986 have focused on comparative morphology and the clear differentiation of Ostertagiinae, primarily from wild ruminants, that have been reported or may potentially occur in domestic bovids. Among these are species which infect wild and domestic sheep (Marshallagia marshalli/Marshallagia occidentalis), bovids (Ostertagia bisonis), and cervids (Ostertagia mossi/Ostertagia dikmansi, Ostertagia leptospicularis/Ostertagia kolchida, Ostertagia gruehneri/Ostertagia arctica, Mazamastrongylus odocoilei and Mazamastrongylus pursglovei) in North America. A key is presented for identifying 15 species of the Subfamily Ostertagiinae that are parasitic in domestic and wild ruminants of North America. Four exotic species (Camelostrongylus mentulatus, Spiculopteragia spiculoptera (= Spiculopteragia boehmi), Spiculopteragia asymmetrica and Longistrongylus curvispiculum) have been reported in North America, but only in game farms and are not included in the key. Hyostrongylus rubidus, a member of the Ostertagiinae normally parasitic in pigs and only rarely reported from domestic ruminants, is not included in the keys. Additional data from comparative morphology and molecular analyses will promote a reassessment of the generic-level systematics of the Ostertagiinae and allow an evaluation of host-parasite evolution and historical biogeography.

An evaluation of the effectiveness of an educational programme promoting the introduction of routine antenatal enquiry for domestic violence.

OBJECTIVE: a feasibility study to evaluate the effect of an educational programme on midwives' knowledge, skills, attitudes and implementation of routine antenatal enquiry for domestic violence. DESIGN: pre-, post- and follow-up survey. SETTING: an acute Trust within the South West of England. PARTICIPANTS: 79 of the 82 community midwives (96%) working in the Trust participated in the training programme, with 70 (85%) participating at all three stages of the research. MEASUREMENTS: participating community midwives completed a 38-item questionnaire at three points during the study: before the educational programme to provide base-line data, post-test immediately after the programme, and at 6 months follow-up. The questionnaire was divided into the following categories: views of professional education, knowledge of domestic violence, attitudes to domestic violence, efficacy beliefs and issues of practice development. The aim of the study was to identify any differences between pre- and post-implementation test data in relation to all the areas identified. Repeated multivariate analysis of variance was used to examine changes between pre-, post- and follow-up measures of knowledge, attitudes and efficacy. Hierarchical regression was used to identify potential influences on post-training disclosure rates using pre-, post- and follow-up measures as predictors. FINDINGS: the programme was positively received by participants, particularly in relation to an increased awareness and confidence in dealing with domestic violence. It was also associated with improvements in knowledge, attitudes and efficacy at post-test. These changes declined but remained above pre-test levels at 6 months follow-up. Levels of current and previous experiences of abuse obtained by midwives were predicted by past experience of dealing with the issue and efficacy scores immediately after and at 6 months after programme delivery. Rates of enquiry after programme introduction were lower than anticipated, with midwives routinely asking only 50% of the time. However, the key barrier identified was the presence of a male partner. IMPLICATIONS FOR PRACTICE: the effect of routine enquiry for domestic violence on midwifery role development needs further exploration before universal introduction. Seeing women alone at least once during a pregnancy would clearly increase opportunities for directly asking about violence and allowing safe disclosure. Where enquiry is introduced, midwives should be given access to validated educational programmes and structured ongoing support if enquiry is to be sustained over time. Although further evaluations are necessary, it may be advisable to focus on skills-based programmes that increase midwives' confidence and prioritise support and safety aspects for midwives and women during enquiry about domestic violence.

Domestic violence, sexual ownership, and HIV risk in women in the American deep south.

Domestic violence and sexual abuse are important correlates of HIV risk in women. This paper examines the links between HIV risk and domestic violence in women in a region with the highest HIV/AIDS rates in the United States. The theoretical framework incorporates Butler's (1993) and (1990) concept of performative gender and Collins' (2000) "controlling images" of African American women as a context for domestic violence in the Deep South. Two focus groups were convened to develop a definition of domestic violence as HIV risk; 50 in-depth individual interviews of HIV-positive women were subsequently conducted for specific information on the topic. A final focus group was conducted for verification and feedback. The interview data revealed that controlling images of women as sexualized bodies were enacted through rape, sexual coercion, and name-calling in intimate relationships. The main finding was that the women lacked the ability to control sexual activities (including condom use) in abusive relationships with HIV-positive men. The women used various strategies to escape abusive partners and to obtain treatment for HIV/AIDS. The study concludes that the links between gender inequity, domestic violence, and HIV transmission should appear in prevention materials to encourage domestic violence screening in health settings, and to provide abused women with information on the not-so-obvious risks of being infected in abusive relationships.

The role of wild animal populations in the epidemiology of tuberculosis in domestic animals: how to assess the risk.

Tuberculosis is present in wild animal populations in North America, Europe, Africa and New Zealand. Some wild animal populations are a source of infection for domestic livestock and humans. An understanding of the potential of each wild animal population as a reservoir of infection for domestic animals is reached by determining the nature of the disease in each wild animal species, the routes of infection for domestic species and the risk of domestic animals encountering an infectious dose. The mere presence of infection in a wild animal population does not of itself provide evidence of a significant wildlife reservoir. Although at times counterintuitive, wildlife populations with high disease prevalence may not necessarily have a role in the epidemiology of disease in domestic livestock. The key concepts used in deciding whether an infected wild animal population is involved in the epidemiology of tuberculosis in domestic livestock is illustrated by reference to six well-researched cases: the feral pig (Suis scrofa) and feral Asian water buffalo (Bubalus bubalis) in Australia, white tailed deer (Odocoileus virginianus) in Michigan, and the brushtail possum (Trichosurus vulpecula) and other species, such as the ferret (Mustela furo), in New Zealand. A detailed analysis of Mycobacterium bovis infection in the Eurasian badger (Meles meles) in Ireland and their role as a reservoir of infection for cattle is also presented.

Domestic violence and the trauma surgeon.

BACKGROUND: Domestic violence has become increasingly recognized as a public health problem, and was declared a national epidemic by C. Everett Koop in 1992. In the United States, 1 to million women yearly suffer injuries due to domestic violence, and 30% to 50% of female homicides are committed by a present or former partner. The majority of these murder victims had either been seen in emergency rooms for prior domestic violence-related injuries, or had reported these injuries to the police. It is estimated that 50% of all acute injuries and 21% of all injuries in women requiring urgent surgery ar the result of partner abuse. DATA SOURCE: Medline and current literature review. CONCLUSIONS: Health care professionals in the emergency room are an important contact with the victims of domestic violence, and timely identification and intervention can save lives. Overall, upwards of 35% of all emergency room visits by women are the result of domestic violence, whether due to acute injury, problems during pregnancy, or stress-related complaints. Unfortunately, domestic abuse is infrequently disclosed voluntarily by the patient, and often overlooked by the treating physician. Thus, the purpose of this review is to familiarize surgeons with the presentation and management of victims of this hidden epidemic.

Orbital fractures in women due to sexual assault and domestic violence.

PURPOSE: Because domestic violence and sexual assault have a widespread societal and medical impact, this retrospective study was designed to determine the frequency of sexual assault and domestic violence as causes of orbital fractures in women. METHODS: The records of 54 consecutive patients with orbital fractures presenting to the Ophthalmic Plastic and Orbital Surgery service of Penn State University's Department of Ophthalmology were reviewed. The type of trauma resulting in each patient's orbital injury was identified. The frequency of orbital fractures resulting from sexual assault or domestic violence was determined. RESULTS: The study included 35 male and 19 female patients, ranging in age from 27 months to 63 years. Orbital fracture was the result of sexual assault or domestic violence in one third of the female patients, but no male patients. Motor vehicle accidents accounted for another 31.6 percent of orbital fractures in female patients. CONCLUSIONS: Based on this retrospective study, sexual assault and domestic violence are frequent causes of orbital fractures in women. Healthcare workers evaluating female patients with orbital fractures should have a high index of suspicion regarding sexual assault or domestic violence as a possible origin of the injury. A pointed but sensitive approach may be necessary to elicit this history from the patient.

Bending strength of upper canine tooth in domestic dogs.

The bending strength of the upper canine tooth is analyzed on 51 domestic dogs of various breeds. Data show that canine tooth length is greater among small domestic dogs when compared to small wild dogs, and large wild dogs when compared among large domestic dogs. Tooth strength is also greater among small domestic dogs and large wild dogs. The greater tooth strength of the small domestic dogs may be attributed to the idea that small domestic dogs are closer in ancestry to the grey wolf (Canis lupus) than are small wild canids. Skull foreshortening and tooth strength appear to be correlated in the canidae.

A continuous improvement process for health providers of victims of domestic violence.

BACKGROUND: Health care providers can play an important role in the prevention of domestic violence through established processes of identification, safety assessment, validation, documentation, and referral. In 1998 the Safe Family Project, funded by University Health System (UHS), affiliated with University of Texas Health Science Center at San Antonio, provided for a clinical review of existing services for victims of domestic violence. A subsequent review of the health system's policy and clinical practice supported the need for resources and training and for an improved care process for victims of domestic violence. THE CONTINUOUS IMPROVEMENT PROCESS (CIP) MODEL: UHS adapted the Shewhart cycle of activities popularly referred to as PDSA (plan change, do change, study results, act on results), a systematic, process-focused approach to achieving continuous and measurable improvement, as its CIP model, and it formed a process improvement team. This process led to translation of research findings into best practice guidelines for treatment of domestic violence and staff education. RESULTS: Significant improvements were made in the overall qualitative chart reviews, although the diagnostic coding (using ICD-9 codes and e-codes) did improve. The CIP can be replicated in other settings to improve the care of victims of domestic violence. DISCUSSION: The CIP effort is being extended to outpatient facilities, and managers have requested that the training manual be replicated and placed throughout UHS as a resource manual. Other activities are intended to improve prevention of domestic violence and intervention when it occurs.

A prospective cohort study of the impact of domestic violence on young teenage pregnancy outcomes.

INTRODUCTION: The incidence of domestic violence among pregnant Australian teenagers is higher than rates reported for the general community. However, there are limited data that address the impact of this abuse upon pregnancy outcome. We have examined the significant antenatal associations of domestic violence in young teenage pregnancy, and the impact of this abuse upon pregnancy outcome. DESIGN, SETTING, PARTICIPANTS: A multicenter prospective cohort study was performed between January 1, 1997 and June 30, 1999. Patients were interviewed and completed questionnaires in the antenatal period to establish whether they were victims of domestic violence. Labor and delivery details were independently collated after discharge for mother and infant. Data were analyzed using an analysis of variance, with a P-value of 0.05 considered significant. RESULTS: Of 537 patients enrolled in the study, 157 (29.2%) were victims of domestic violence; 380 (70.8%) were not and acted as pregnant teenage controls. Key findings were that teenage victims of domestic violence (VDV) were more likely to smoke, drink alcohol, or use illegal drugs than controls (P < 0.0001). VDV had a higher incidence of infectious morbidity and Pap smear abnormalities (P < 0.007) and psychosocial pathology (P < 0.0001) than controls. A higher incidence of puerperal and neonatal morbidity was observed in VDV and their newborns compared to controls (P < 0.007). The estimated cost of hospital care for teenage VDV was double that of the Australian average. CONCLUSION: We need to identify all teenage mothers exposed to domestic violence and provide them with expert intervention services. Early intervention programs are likely to be cost effective.

Prevalence of children's exposure to domestic violence and child maltreatment: implications for prevention and intervention.

The purpose of this paper is to review research on the prevalence of children's exposure to domestic violence, to consider the available literature on the co-occurrence of domestic violence and child maltreatment, and to gain more understanding about the impact of exposure on children. There is clear evidence indicating that both severe and moderate violence occurs frequently in homes among family members and that children are exposed to this violence. However, because of differing definitions of what constitutes domestic violence and variability in research methodologies for collecting the data, there are significant discrepancies in prevalence reports across studies. Of great concern is the immediate impact on the children and the long-term consequences for their later relationships. Fewer studies have been done on the co-occurrence of domestic violence and child maltreatment. However, it is likely that children who live in homes where domestic violence occurs are more likely to be abused and neglected. On the basis of available research, there is little doubt that vast numbers of children are exposed to domestic violence and that children's responses vary widely depending on their risk and vulnerability, as well as the structure of their environments A developmental risk and protective factors framework will be used to integrate the information on children's exposure to violence.

Posthatch growth of the digestive system in wild and domesticated ducks.

1. Our study was designed to test the hypothesis that domestication and artificial selection have influenced the posthatch growth and functioning of the gastrointestinal (GI) tract of ducks. The mass and length of the GI tract organs, the growth of intestinal villi, the intestinal surface area and the activities of brush border digestive enzymes were measured in a commercial strain of Pekin duck and its wild ancestor, the mallard (Anas platyrhynchos), at regular intervals between hatch and 16 weeks of age. 2. The growth of the digestive organs, with respect to body mass, was described using allometry. Allometric mass exponents were then used to calculate body 'mass-corrected', or 'relative' organ masses, relative surface areas and relative enzyme activities. There were appreciable differences between data presented on a mass-specific (g/kg) and a mass-corrected (g/kg(b)) basis, which highlighted the importance of correcting for the complete effects of body mass when comparing the growth and function of the digestive system between strains. 3. While the process of domestication has induced major changes in the absolute characteristics of the GI tract, it has failed to have the same effect on the relative characteristics. During the first 2 weeks posthatch, the relative masses of the majority of digestive organs, and the GI tract as a whole, were the same in both strains. During weeks 3 to 5, domesticated ducks maintained higher absolute growth rates of the body and the GI tract, with the support of relatively smaller digestive organs. The relative masses of the small intestine and the GI tract as a whole were 45 and 66% higher respectively in mallards than in Pekin ducks during this period. 4. Domesticated ducks had elevated digestive enzyme activity and a greater absorptive surface area than mallards throughout development, both in absolute and relative terms. This appears to compensate for the failure of the relative masses of digestive organs in domesticated ducks to accompany the increased body mass and growth rate. 5. At 5 weeks posthatch, the absolute mass of the small intestine in domesticated ducks declined by 38%. There is no obvious explanation for this decline because the masses of other digestive organs, daily feed intake and body mass continued to rise.

Haematological and immunological variables in a domesticated and wild subspecies of ostrich (Struthio camelus).

1. Domesticated ostriches have been selected rigorously for productive traits with little concern for immunological responses, in contrast to wild ostriches. 2. We hypothesised that the immunological responses of wild and domesticated ostriches would differ. Total leucocyte counts, differential counts, heterophil: lymphocyte ratios, phagocytic activity, lysosome levels and anti-sheep red blood cell (SRBC) antibody titres (total, IgG, IgM) were compared between domesticated (n=3) and wild (n=3) ostrich subspecies. 3. Total leucocytes, lymphocytes and heterophils were similar in the 2 subspecies, but basophils and eosinophils were lower in the wild than in the domesticated ostriches. Lysosome concentrations and phagocytic activities were higher in the wild ostriches. 4. Total and IgM antibody titres to SRBC reached peak values quicker in the domesticated than in wild ostriches. IgG development patterns were similar. 5. The results suggest that a stronger non-specific immune response was shown by the wild ostriches (higher phagocytosis and lysozymes) whereas a stronger specific immune response was shown by the domesticated ostriches (peak values of anti-SRBC antibody titres were reached more quickly).

Perceptions of domestic violence: a dialogue with African American women.

Although empirical research has accumulated over the past 20 years regarding African Americans and domestic violence, many questions remain about African American perceptions of domestic violence. This article explores African American women's perceptions about domestic violence through three focus groups held at a New York social services agency. The findings point to the need to better understand diverse perceptions of domestic violence, to find culturally competent methods of addressing the inaccessibility of domestic violence services, to increase culturally appropriate public education, and to conduct more research on the connection between domestic violence and child welfare in communities of color.

Consequences of selection on muscle composition. A comparative study on gracilis muscle in wild and domestic pigs.

European domestic pigs are derived from the European wild pig by genetic selection and differ in their muscular-growth ability. Thus, it was the aim of this study to investigate the consequences of genetic selection on muscle composition and fibre size in the gracilis muscle. Fibre typing based on the ATPase reaction revealed that this muscle in wild pigs is composed mainly of type-I and -IIa fibres, whereas, in domestic pigs, type-IIb fibres were predominant. For all fibre types, domestic pigs had about threefold larger fibres than wild pigs. Type-I fibres tended to be the smallest fibres in domestic pigs, but the largest fibres in wild pigs, which may be due to long-term training effects in the free-ranging animals. Giant fibres as an indicator of degeneration were obvious only in the domestic-pig samples. Their occurrence, as well as the larger fibre size and the predominance of type-IIb fibres in domestic pigs, may be ascribed to high concentrations of growth hormone. It is concluded that selection for muscular growth may favour metabolic dysbalances within the muscle and, therefore, degenerative processes.

Domestic violence in South Australia: a population survey of males and females.

OBJECTIVE: To determine the self-reported prevalence of domestic violence in South Australian adults and to examine the associated risk factors, demographic factors and related health issues using computer-aided telephone interviewing (CATI) methodology. SAMPLE: A representative random sample of South Australian adults aged 18 years and over selected from the Electronic White Pages. Overall, 6,004 interviews were completed (73.1% response rate). RESULTS: In total, 17.8% of adults in South Australia reported some form of domestic violence by a current or an ex-partner. Demographic factors such as low household income, unemployment or part-time employment and health variables such as poor to fair self-reported health status and alcohol abuse problems were found to have a significant relationship with domestic violence. CONCLUSIONS: Approximately one in five South Australian adults report physical and emotional abuse from current or ex-partners, of whom the majority are women who are separated, divorced or never married and on lower incomes. Telephone interviewing is a cost-effective method of identifying prevalence estimates of domestic violence when compared with data collection by way of police reports or hospital emergency statistics. IMPLICATIONS: Domestic violence is a serious public health concern often 'hidden' by the lack of appropriate data. This study has shown that domestic violence is frequent and has important social, economic and health consequences.

Demography, hunting ecology, and pathogen exposure of domestic dogs in the Isoso of Bolivia.

Disease is increasingly recognized as a threat to the conservation of wildlife, and in many cases the source of disease outbreaks in wild carnivores is the domestic dog. For disease to spill over from a domestic to a wild population, three conditions must be satisfied: susceptibility of the wild species, presence of the disease agent in the domestic population, and contact between the two populations of interest. We investigated the potential for disease spillover from the domestic dog population to the wild carnivore population in the Isoso of Bolivia, an area of tropical dry forest contiguous with a national park. Using questionnaires and discussions with residents, we gathered data on the demography of dogs in the Isoso, including adult and neonatal mortality, litter size, and hunting frequency. We analyzed a large data set containing self-recorded information on hunting in various communities of the Isoso to determine the extent of dog participation in hunting and the duration of hunting trips. Finally, we took blood samples from dogs in the Isoso for a serosurvey of common canine pathogens. More than 95% of dogs had positive titers to canine distemper virus and canine parvovirus. There was also a high seroprevalence in dogs for other pathogens, a high population turnover of dogs (which may allow diseases to be maintained endemically), and frequent opportunities for contact between domestic and wild carnivores. Based on our results and the susceptibility of wild species previously reported in the literature, domestic dogs represent a disease risk for wildlife in the Bolivian Isoso.
