Abstract
OBJECTIVE Long-acting injectable antipsychotic medications (LAIAPs) are a valuable and underused treatment for patients with chronic mental illnesses such as schizophrenia and bipolar disorder. This study aimed to examine prescription patterns of LAIAPs among outpatient mental health care service providers in the United States. METHODS The authors conducted a secondary analysis of the 2020-2021 National Mental Health Services Survey to assess the percentage of outpatient mental health care service providers (N=9,433) that prescribed LAIAPs to patients. Descriptive statistics were calculated to describe the overall frequency of outpatient facilities prescribing LAIAPs and differences in the specific LAIAPs prescribed. The authors also conducted multivariable analyses to identify facility characteristics associated with likelihood of LAIAP prescribing. RESULTS Across all outpatient mental health care service providers, 30.6% prescribed LAIAPs. Community mental health centers were most likely to prescribe LAIAPs (62.6%), whereas partial hospitalization and day programs were least likely (32.1%). The most used LAIAP was paliperidone palmitate (77.7%), and the least used was olanzapine pamoate (29.6%). Providers with programs specifically for patients with serious mental illness (59.5%) and providers with a dedicated first-episode psychosis program (58.2%) were more likely to prescribe LAIAPs than were providers without such programming. CONCLUSIONS Prescription of LAIAPs is limited at outpatient mental health care service providers in the United States. Expansion of these services and diversification of delivery models are needed to improve LAIAP prescriptions, which are associated with improved patient outcomes across a broad range of measures.

Abstract
INTRODUCTION Emergency departments (ED) provide trauma-informed care to sexual assault (SA) survivors and connect them with comprehensive services. Through surveying SA survivor advocates, we aimed to 1) document updated trends in the quality of care and resources offered to SA survivors and 2) identify potential disparities according to geographic regions in the US, urban vs rural clinic locations, and the availability of sexual assault nurse examiners (SANE). METHODS We conducted a cross-sectional study between June-August 2021, surveying SA advocates who were dispatched from rape crisis centers to support survivors during ED care. Survey questions addressed two major themes in quality of care: staff preparedness to provide trauma-response care; and available resources. Staff preparedness to provide trauma-informed care was assessed through observations of staff behaviors. We used Wilcoxon rank-sum and Kruskal-Wallis tests to analyze differences in responses according to geographic regions and SANE presence. RESULTS A total of 315 advocates from 99 crisis centers completed the survey. The survey had a participation rate of 88.7% and a completion rate of 87.9%. Advocates who indicated that a higher proportion of their cases were attended by SANEs were more likely to report higher rates of trauma-informed staff behaviors. For example, the recalled rate of staff asking patients for consent at every step of the exam was significantly associated with SANE presence (P < 0.001). With respect to access to resources, 66.7% of advocates reported that hospitals often or always have evidence collection kits available; 30.6% reported that resources such as transportation and housing are often or always available, and 55.3% reported that SANEs are often or always part of the care team. The SANEs were reported to be more frequently available in the Southwest than in other US regions (P < 0.001) and in urban as opposed to rural areas (P < 0.001). CONCLUSION Our study indicates that support from sexual assault nurse examiners is highly associated with trauma-informed staff behaviors and comprehensive resources. Urban-rural and regional disparities exist regarding access to SANEs, suggesting that elevating nationwide quality and equity in care of survivors of sexual assault requires increased investments in SANE training and coverage.

Abstract
Interactions between emergency department (ED) staff and sexual assault (SA) survivors can be a source of retraumatization for survivors, increasing their risk of posttraumatic stress and decreasing utilization of longitudinal medical care. Little is known about nationwide trends in ED staff attitudes and behaviors toward survivors, including the impact of survivor identity. We conducted a survey to determine if survivor identity influenced ED staff behaviors. A nationwide survey of SA patient advocates was conducted between June and August 2021. Advocates are volunteers or staff dispatched from rape crisis centers to support survivors during ED care. Advocates participated in an online survey to determine the frequency of observing six potentially retraumatizing provider attitudes and behaviors. Adaptive questioning was used to explore the impact of survivor identity on each attitude or behavior and which identity groups were more likely to be affected. Three hundred fifteen advocates responded to the survey. Less than 10% indicated that ED staff often or always convey disbelief or blame to survivors. Almost 75% of advocates indicated that they often or always observe ED staff showing empathy to survivors. Disparities were found in provider attitudes. Over 75% of advocates observed that survivors' mental health status or substance use impacted conveyed belief from providers. Patients who were intoxicated when assaulted, had psychiatric disorders, were Black, Hispanic/LatinX, or indigenous, or were not cis-females were more likely to experience disbelief. Patients who were white and/or cis-gender females were more likely to be pressured by ED staff to complete the forensic exam and/or report to the police. Our study documents disparities in ED staff behavior towards SA survivors according to survivor identity. Given that post-assault ED interactions are critical turning points in survivors' future medical processes, disparities in ED care may be linked to larger disparities in healing from trauma.

Abstract
In the aftermath of the Supreme Court's Dobbs vs. Jackson Women's Health decision, acute care surgeons face an increased likelihood of seeing patients with complications from both self-managed abortions and forced pregnancy in underserved areas of reproductive and maternity care throughout the USA. Acute care surgeons have an ethical and legal duty to provide care to these patients, especially in obstetrics and gynecology deserts, which already exist in much of the country and are likely to be exacerbated by legislation banning abortion. Structural inequities lead to an over-representation of poor individuals and people of color among patients seeking abortion care, and it is imperative to make central the fact that people of color who can become pregnant will be disproportionately affected by this legislation in every respect. Acute care surgeons must take action to become aware of and trained to treat both the direct clinical complications and the extragestational consequences of reproductive injustice, while also using their collective voices to reaffirm the right to abortion as essential healthcare in the USA.

Abstract
BACKGROUND Patient-physician communication is key to better clinical outcomes and patient well-being. Communication between trauma patients and their physicians remains relatively unexplored. We aimed to identify and characterize the range of strengths and challenges in patient-physician communication in the setting of trauma care. METHODS A qualitative, grounded theory approach was used to explore communication strengths and challenges for patients and residents. Patients previously admitted to the trauma service for violent injuries were recruited and interviewed in-person during their trauma clinic appointments. Surgical residents were recruited via email and interviewed virtually via Zoom. Anonymous, semistructured interviews were conducted until thematic saturation was reached. RESULTS Twenty-nine interviews with patients and 14 interviews with residents were conducted. Patients reported feeling ignored and misunderstood and having inadequate communication with physicians. Residents cited lack of time, patients' lack of health literacy, differences in background, and emotional responses to trauma as barriers to effective communication with patients. Patients and residents reported an understanding of each other's stressors, similar emotional experiences regarding traumatic stress, and a desire to communicate with each other in greater depth both inside and outside of the hospital. CONCLUSION Trauma patients and residents can feel disconnected due to the lack of time for thorough communication and differences in background; however, they understand each other's stressors and share similar emotional responses regarding trauma and a desire for increased communication, connection, and solidarity. Leveraging these shared values to guide interventions, such as a resident curriculum, may help bridge disconnects and improve their communication. LEVEL OF EVIDENCE Therapeutic/Care Management; Level IV.

Abstract
BACKGROUND The majority of adolescents with type 1 diabetes (T1D) integrate social media engagement into their daily lives. The aim of this study was to explore adolescents' experiences and perspectives discussing their T1D on social media. METHODS Semi-structured interviews with adolescents with T1D were conducted in person and via telephone. Questions focused on the participant's experiences utilizing social media to discuss T1D and factors that informed the nature of T1D-related social media engagement. Open coding and thematic content analysis were used to identify emergent themes that aligned with accepted domains of social media affordances. RESULTS Participants included 35 adolescents with T1D. Adolescents' experiences related to discussing T1D on social media aligned with four affordances of social media: identity, cognitive, emotional, and social. The identity affordances of social media platforms allowed adolescents to curate online personas that selectively included their diagnosis of T1D, while managing the potential negative emotional and social implications linked to the stigma of T1D. Adolescents who decided to discuss T1D on social media leveraged cognitive affordances by providing and receiving diabetes management advice, emotional affordances by obtaining affirmation from peers, and social affordances by extending their network to include other individuals with T1D. CONCLUSIONS Adolescents with T1D flexibly leverage the affordances offered by social media to access emotional support, information, and identity affirmation resources while navigating stigma-based social consequences. Our findings highlight the value of developing tools to support adolescents with T1D in comfortably discussing and receiving appropriate support about T1D on social media.

Abstract
BACKGROUND To assess ethical concerns associated with participation in a financial incentive (FI) programme to help adolescents with type 1 diabetes improve diabetes self-management. METHODS Focus groups with 46 adolescents with type 1 diabetes ages 12-17 and 38 of their parents were conducted in the Seattle, Washington metropolitan area. Semistructured focus group guides addressed ethical concerns related to the use of FI to promote change in diabetes self-management. Qualitative data were analysed and emergent themes identified. RESULTS We identified three themes related to the ethical issues adolescents and parents anticipated with FI programme participation. First, FI programmes may variably change pressure and conflict in different families in ways that are not necessarily problematic. Second, the pressure to share FIs in some families and how FI payments are structured may lead to unfairness in some cases. Third, some adolescents may be likely to fabricate information in any circumstances, not simply because of FIs, but this could compromise the integrity of FI programmes relying on measures that cannot be externally verified. CONCLUSIONS Many adolescents with type 1 diabetes and their parents see positive potential of FIs to help adolescents improve their self-management. However, ethical concerns about unfairness, potentially harmful increases in conflict/pressure and dishonesty should be addressed in the design and evaluation of FI programmes.

Abstract
Background Placebo‐controlled trials play an important role in the evaluation of healthcare interventions. However, they can be challenging to design and deliver for invasive interventions, including surgery. In‐depth understanding of the component parts of the treatment intervention is needed to ascertain what should, and should not, be delivered as part of the placebo. Assessment of risk to patients and strategies to ensure that the placebo effectively mimics the treatment are also required. To date, no guidance exists for the design of invasive placebo interventions. This study aimed to develop a framework to optimize the design and delivery of invasive placebo interventions in
RCTs. Methods A preliminary framework was developed using published literature to: expand the scope of an existing typology, which facilitates the deconstruction of invasive interventions; and identify placebo optimization strategies. The framework was refined after consultation with key stakeholders in surgical trials, consensus methodology and medical ethics. Results The resulting DITTO framework consists of five stages: deconstruct treatment intervention into constituent components and co‐interventions; identify critical surgical element(s); take out the critical element(s); think risk, feasibility and role of placebo in the trial when considering remaining components; and optimize placebo to ensure effective blinding of patients and trial personnel. Conclusion DITTO considers invasive placebo composition systematically, accounting for risk, feasibility and placebo optimization. Use of the framework can support the design of high‐quality RCTs, which are needed to underpin delivery of healthcare interventions.

Abstract
Outcome reporting in bariatric surgery needs a core outcome set (COS), an agreed minimum set of outcomes reported in all studies of a particular condition. The aim of this study was to summarize outcome reporting in bariatric surgery to inform the development of a COS. Outcomes reported in randomized controlled trials (RCTs) and large non-randomized studies identified by a systematic review were listed verbatim and categorized into domains, scrutinizing the frequency of outcome reporting and uniformity of definitions. Ninety studies (39 RCTs) identified 1,088 separate outcomes, grouped into nine domains with most (n = 920, 85%) reported only once. The largest outcome domain was 'surgical complications', and overall, 42% of outcomes corresponded to a theme of 'adverse events'. Only a quarter of outcomes were defined, and where provided definitions, which were often contradictory. Percentage of excess weight loss was the main study outcome in 49 studies, but nearly 40% of weight loss outcomes were heterogeneous, thus not comparable. Outcomes of diverse bariatric operations focus largely on adverse events. Reporting is inconsistent and ill-defined, limiting interpretation and comparison of published studies. Thus, we propose and are developing a COS for the surgical treatment of severe and complex obesity.

Abstract
Serum pepsinogen levels and Ostertagia ostertagi populations in clinically normal grass-fed bullocks were investigated in three groups of 10 prime cattle aged between 2.5 and 2.75 years slaughtered in late summer (February), early autumn (March) and late autumn (May) respectively. Apart from occasional foci of mucosal hyperplasia abomasa were grossly normal. Serum pepsinogen levels ranged between 0.2 and 2.5 i.u./l with group means of 1.4, l.5 and 1.3 i.u./l. O. ostertagi counts ranged between 0 and 5,194 with group means of 734,630 and 701 worms. The composition of the worm populations varied with a higher proportion of adults recovered in February and very few worms from most cattle in March, suggesting the termination of a parasite generation. An increase in numbers of early fourth-stage larvae in May indicated exposure to a new generation. These changes were not reflected in the pepsinogen levels. The findings are discussed in relation to the adequacy of the pepsinogen assay as a diagnostic aid in field infections, animal age, and correlations between pepsinogen levels and parasite populations.

Abstract
We set out to examine whether a multidisciplinary out-patient dysphagia referral triage service would shorten the duration of a patient's referral process and direct patients to the correct specialty. A review was carried out of patients referred with dysphagia before and after the introduction of a multidisciplinary out-patient dysphagia service, from February 2001 to April 2001 and from January 2002 to March 2002, inclusive.One hundred and eight patients were referred in total. The length of time until the first appointment was reduced from four to three weeks (median; range one to 23; p<0.001). The number of instrumental investigations was reduced, with a median of one instrumentation per patient under the new service, compared with two in those under the standard service (p<0.001). Attendance to hospital was also reduced, with 45 per cent of patients under the new service requiring only one appointment, compared with 13 per cent in those under the standard service (p<0.001).The multidisciplinary out-patient dysphagia service was associated with significant reductions in waiting times, in the number of instrumental investigations and in the duration of the patient's referral process.

Abstract
Abnormalities of cerebral white matter are present in a majority of patients with Alzheimer's disease (AD) and probably contribute to motor dysfunction and cognitive impairment. The white matter abnormalities are usually attributed to degenerative vascular disease and cerebral amyloid angiopathy (CAA) but the evidence is scanty or inconclusive. In the present study we examined sections of frontal lobe from 125 autopsy-confirmed cases of AD and assessed the relationship of degenerative large and small vessel disease, CAA, parenchymal Abeta load and APOE genotype, to several objective measures of white matter damage: extent of immunolabelling for glial fibrillary acidic protein (GFAP), axonal accumulation of amyloid precursor protein (APP), axon density in superficial and deep white matter, and intensity of staining for myelin. We found no association between atherosclerosis, arteriolosclerosis, CAA or APOE genotype and white matter damage. However, labelling of white matter for GFAP correlated strongly with the parenchymal Abeta load (P = 0.0003) and with APP accumulation (P = 0.008). Our findings suggest that severity of frontal white matter damage in AD is closely related to parenchymal Abeta load and that in most cases the contribution of degenerative vascular disease, CAA and APOE is relatively minor.

Abstract
Over 90% of patients with Alzheimer's disease (AD) develop cerebral amyloid angiopathy (CAA). Severe dyshoric CAA, in which amyloid extends into the surrounding brain parenchyma, may be associated with adjacent clustering of tau-immunopositive neurites but the relationship of CAA to neurofibrillary pathology has not been systematically investigated. In the present study this relationship was examined in sections of frontal, temporal and parietal cortex from 25 AD patients with moderate to severe CAA and 26 with mild or absent CAA. We measured immunolabelling of abnormally phosphorylated tau adjacent to A beta-laden and non-A beta-laden arteries and arterioles, and in cortex away from arteries and arterioles. We also analysed the possible influence of APOE genotype on these measurements. There were no significant differences between the lobes in measurements of tau labelling, either around blood vessels or elsewhere in the cortex. However, tau labelling around A beta-laden arteries and arterioles significantly exceeded that around non-A beta-laden blood vessels (P<0.001) and this, in turn was greater than the labelling of cortex away from blood vessels (P<0.001). There was no association between APOE epsilon 4 and the immunolabelling density for tau, whether around amyloid- or non-amyloid-laden arteries and arterioles, or in the cerebral cortex away from these. We propose that both CAA and peri-vascular accumulation of hyperphosphorylated tau may be a consequence of elevated levels of soluble A beta around cortical arteries and arterioles.

Abstract
The relative amounts of amyloid beta-protein (A beta) in cerebral blood vessels and parenchyma vary considerably amongst patients with Alzheimer's disease (AD). Although several mechanisms have been proposed to explain this variability, the underlying genetic and environmental determinants are still unclear, as are the functional consequences. Polymorphisms in APOE, the gene for apolipoprotein E (ApoE), influence the risk of developing AD and of deposition of A beta within the brain. We examined the relationship between the APOE genotype and the relative extent of accumulation of A beta as plaques within the cerebral parenchyma and in cortical blood vessels in the form of cerebral amyloid angiopathy (CAA), in autopsy brain tissue from 125 AD cases and from 53 elderly, neurologically normal controls of which 19 had CAA without other neuropathological features of AD. In the AD cases, we also assessed whether the severity of CAA was related to the age of onset and duration of dementia, risk factors for atherosclerotic vascular disease, and histologically demonstrable cerebral infarcts or foci of haemorrhage. The APOE genotype was determined by a standard polymerase chain reaction-based method. Paraffin sections of frontal, temporal and parietal lobes were immunolabelled for A beta and the parenchymal A beta load (total A beta minus vessel-associated A beta) was quantified by computer-assisted image analysis. CAA severity was scored for cortical and leptomeningeal vessels. The relevant clinical data were obtained from the database of the South West Brain Bank. In AD, we found the severity of CAA to be strongly associated with the number of epsilon 4 alleles (P < 0.0001) but the parenchymal A beta load to be independent of APOE genotype. Cases with severe CAA had a lower parenchymal A beta load than had those with moderate CAA (P = 0.003). Neither the severity of CAA nor the parenchymal A beta load correlated with age of onset, duration of disease or age at death, and the severity of CAA also did not correlate with the presence of cerebral infarcts or foci of haemorrhage. These findings indicate that possession of the APOE epsilon 4 allele favours vascular over parenchymal accumulation of A beta in AD. This may influence the pathogenesis of neurodegeneration in epsilon 4-associated AD.

Abstract
The aim of this study was to describe the information and support needs of women who have primary relatives with breast cancer. The Information and Support Needs Questionnaire (ISNQ) was developed and revised from previous qualitative and pilot studies. The ISNQ addressed concepts of the importance of, and the degree to which, 29 information and support needs related to breast cancer had been met. The study sample consisted of 261 community-residing women who had mothers, sisters, or a mother and sister(s) with breast cancer. Data were collected using a mailed survey. In addition to the ISNQ, additional items addressed family and health history, breast self-care practices, perception of the impact of the relative's breast cancer and other variables. Also included were established and well-validated measures of anxiety and depression. The findings document women's priority information and support needs. The information need most frequently identified as very important was information about personal risk of breast cancer. Other highly rated needs addressed risk factors for breast cancer and early detection measures. Generally, the women perceived that their information and support needs were not well met. These findings illuminate needs of women for more information and support when they have close family relatives with breast cancer and opportunities for primary care providers to assist women in addressing their needs.

Abstract
The goal of this study was to explore and describe the experience of being or having a child with cancer in a rural geographic area. An exploratory, descriptive study was conducted that used semistructured, in-depth, tape-recorded interviews as the primary data collection method. Ten rural families who each had a child with cancer formed the sample. Data were analyzed with qualitative analysis procedures. Families' descriptions revealed that their experiences were fraught with challenges that were due to living a great distance from the cancer treatment center. Descriptions of their experiences are presented in this report. Recommendations for health care professionals, particularly pediatric oncology nurses, to assist rural families in coping with their challenges are also offered.

Abstract
A smoking reduction and cessation program was implemented with registered nurses in 3 Canadian provinces. Nurses (n = 117) participated in either an 8-week group or self-directed program using a resource specifically designed for nurses. Questionnaires were administered prior to and at the end of the 8-week interventions and at 6 and 12 months postintervention. Statistically significant changes at 8 weeks in nurses' smoking practices were found on the number of nurses continuing to smoke, mean number of cigarettes smoked, and movement in the stage of behavioral change. Attrition and variation in patterns of quitting over the 12-month study period made assessing participants' longer term outcomes difficult. This study highlights the complexity of assisting nurses to quit smoking and of implementing and evaluating a program based on accepted community health models of practice.

Abstract
PURPOSE To identify the cognitive processes nurses use in their decision-making in long- and short-term care settings in five countries, and the demographic variables associated with their decision-making. METHOD AND SAMPLES: The instrument used was a 56-item questionnaire that has been shown to be reliable in earlier studies. The sample consisted of five convenience samples of registered nurses working in either geriatric wards (n = 236) or acute medical-surgical wards (n = 223) in hospitals or nursing homes in Canada, Finland, Sweden, Switzerland, and the United States. FINDINGS Five models of decision-making were identified on the basis of factor analysis. They represent both analytical and intuitive cognitive processes. Analytical cognitive processes were emphasized in information collection, problem definition, and planning of care, and intuitive cognitive processes were emphasized in planning, implementing, and evaluating care. Professional education, practical experience, field of practice, and type of knowledge were significantly associated with decision-making models as well as with country of residence of the participants. The highest proportion of analytically oriented decision-makers was found among nurses in long-term care, the decision-making of nurses in short-term care was more intuitively oriented. CONCLUSIONS The results indicate that decision-making of participants varied from country to country and in different nursing situations. Future research should be focused on reasons for these differences, the relationship between the task and the nurses' type of knowledge, and how nurses use their knowledge to make decisions in different nursing situations.

Abstract
OBJECTIVE To describe experiences of women seeking information about their risk of hereditary breast cancer who fail to meet strict eligibility criteria for genetic counseling and testing. DESIGN Qualitative descriptive study. SETTING Hereditary cancer program in western Canada. PARTICIPANTS Women who had received notification of their ineligibility for referral for hereditary breast cancer risk assessment (n = 20) and some of their referring physicians (n = 10). Of 28 attempted contacts, five women had moved, one declined the invitation to participate, and two could not be interviewed because of scheduling conflicts. Ten of 20 physicians declined the invitation to participate. METHOD In-depth, open-ended telephone interviews were conducted. Transcribed interviews were systematically analyzed to identify salient themes. MAIN FINDINGS Three themes emerged. The first theme, "It's always on your mind," points to the profound concern about breast cancer that underlies women's experiences in seeking genetic testing. The second theme, "A test is a test," reflects women's beliefs that the test was relatively simple and similar to other medical tests in that it would provide a definitive answer. The third theme, "Falling through the cracks," captures the experience of ineligibility. Women reacted with a range of emotional responses and were left frustrated in their search for more specific information about their personal risk for breast cancer. Although women were encouraged to contact their physicians, few did. CONCLUSION These findings point to the psychological consequences in women who seek genetic testing for risk of breast cancer when they are told they are ineligible and they are not given adequate information and support.

Abstract
The purpose of this study was to describe the decision-making processes of 369 public health nurses in Canada, Finland, Norway, and the United States, and to discuss any differences observed among these countries. The results indicate that public health nurses used different decision-making models on the job and that these models varied considerably. Five different decision-making models were identified, each exhibiting features of different decision-making theories. The differences between decision making of public health nurses in different countries were statistically significant. The differences in decision making appear to be due to differences in health care systems in the 4 countries and the nature of the nursing task and context.

Abstract
Nursing in Canada is committed to preparing all new graduates at the baccalaureate level for entry to nursing practice by the year 2000. This goal has major implications for community health nursing education and practice. Health care reform is also expected to move care out of the hospital and into the community. It was against this backdrop that the researchers mounted a study on the educational preparation needed for graduates to begin to practice community health nursing. In this paper, the knowledge, professional and personal skills, and experiences that graduates need to begin community practice are reported. The study was carried out within an action-research framework. All major groups of stakeholders involved in community health nursing throughout the study province were involved in the project. This included nurses and administrators from two public health agencies (provincial and municipal), home care nurses, home health nurses (i.e. non-governmental visiting nurses), community health centres, provincial health care and nursing consultants, and faculty from two universities. In addition to the generation of relevant research findings for use by the educational institutions, the study was initiated to set the stage for future and ongoing interactions between the researchers and community experts to implement the findings from the project. Data were collected from 118 participants by means of 27 focus groups of community nurses, administrators and educators. Interviews were tape-recorded, transcribed and analysed using latent content analysis and constant comparison techniques. Findings indicated that qualified nurses from university programmes need a wide range of knowledge, skills and experiences to begin to practice community health nursing. Detailed accounts of these requirements are outlined and the implications for practice and education put forward.

Abstract
In this article, the role of information, support, and communication in promoting adaptation to the risk of breast cancer is reported. These variables emerged from an in-depth study of women at risk for breast cancer because of breast cancer in one or more of their primary (first degree) relatives. Fifty-five women with mothers, sisters, mother and sister, or mother and another primary relative were interviewed using in-depth semi-structured, tape-recorded interviews. After transcription, data were analyzed using qualitative analysis procedures. A three-phase process of adaptation to the risk of breast cancer was uncovered, which was subsequently validated with two study participants. Information, support, and communication emerged as important factors in facilitating the adjustment of women throughout the three phases of the process: as women "lived" the breast cancer experience of their relative; as they developed a perception of their personal risk for breast cancer; and finally as they put the risk of breast cancer "in its place." Despite the importance of information and support, most women had difficulty meeting these needs. Also, communication patterns both within the family and with health professionals were generally not helpful for these women. Issues related to the ill relative as "manager" of cancer-related information, the "ownership style" of the woman at risk, and the accessibility and availability of resources influenced women's adaptation to feelings of risk. Women's needs for information, support, and communication and facilitating factors are described in detail, and recommendations for clinical practice and research offered.

Abstract
We have assessed several age-sensitive indicators of immune status in young (i.e., 6 to 11-month-old) mice of a genetically heterogeneous population to see if these varied in parallel and to determine if one or more of the status indices predicted life span or cancer incidence. We report that the number of memory (i.e., CD44hi) T cells within the CD8 subset is correlated with number of memory cells in the CD4 population, and inversely correlated with the number of naive (i.e., CD45RBhi) CD4 cells at both 6 and 11 months of age, suggesting that the conversion of naive to memory cells may occur at similar rates in both T cell subsets. Mice that ranked high in the proportion of memory T cells (within the CD4 and CD8 pools) at 6 months of age tended to retain their ranking at 11 months, suggesting that the pace or extent of memory cell formation may be a consistent trait that distinguishes mice at least within a genetically heterogeneous population. Mice that at 6 months of age exhibited high levels of CD4 or CD8 memory T cells, low levels of naive CD4 cells, or low levels of T cells able to proliferate in response to Con A and IL-2 were found to be significantly more likely than their littermates to die within the first 18 months of life. Cases of follicular cell lymphoma, lymphocytic and lymphoblastic lymphoma, and hepatic hemangiosarcoma were seen within the group of mice dying at early ages.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The purpose of this paper is to discuss health visitors' construction of difficult work as uncovered in their descriptions of actual cases. The grounded theory approach was used to uncover the processes by which health visitors work with clients in the community. Forty-five experienced health visitors participated in the research. Data were collected using semi-structured, conversational interviews, field notes, and a short data collection form. Findings identified three types of situations in their work which created difficulty for health visitors: concerns about client safety, inappropriate use of health visitor services, and client denial and blocking. Several approaches to dealing with difficult situations were identified. These were labelled as: "more of the same", "wait for a bit", "withdrawal", "fall back on routine visiting", "try something else", and "open up the problem situation/confrontation". The use of approaches was related to factors in the context in the situation in which the health visitor found herself, and factors related to the health visitor and her particular style of practice. This paper assists in understanding how health visitors work with clients in the community to influence health.

Abstract
Biochemical, molecular and morphological markers have been used to monitor the segregation of alleles at major gene loci in microspore-derived lines of four spring barley crosses and their parents. Significant deviations from the expected Mendelian ratios were observed for four of the ten markers studied in the cross. Distorted ratios were associated with loci located on chromosomes 4H and 6H. The differential transmission of alleles was in favour of the responsive parent (Blenheim) used in the anther culture studies. For the α-Amy-1 locus on chromosome 6H, the preferential transmission of Blenheim alleles was most pronounced in the haploid regenerants that were colchicine treated. These results are discussed in relation to the genetic control of androgenetic response in barley and with respect to the exploitation of another culture in barley improvement.

Abstract
Although research activity is increasingly aimed at examining health outcomes of community health nursing care, little empirical literature systematically describes the nurse-client interaction. In this pilot study nurse-client interactions were evaluated to describe their detailed elements. Nineteen such interactions occurring in a Canadian public health department were videotaped by a professional filming crew. The clinical situations included home visits, school health interviews and screening, health classes, and clinic work. The audio portion of the nurse-client exchanges were transcribed from the videotapes onto a computer and analyzed using content analysis. Semi-structured interviews were conducted with nurses and clients after the filming to elicit their perceptions of the interactions. Field notes describing nonverbal and contextual data were also collected and analyzed. The central process identified during the interactions was called "creating common ground." This integrating conceptual schema captured the give and take as each participant defined territory and revealed information. The process varied depending on care context, process skills of the nurse, and willingness of the client to engage.

Abstract
Although literature on community health nursing identifies a nursing role at the community level, there is a lack of clarity about the elements and expected outcomes of this role. In this paper three models of community health practice are presented and discussed in terms of their effectiveness as a basis for nursing practice at the community level. These models are (1) the public health model, (2) community participation model, and (3) community change model. Factors that affect the effectiveness of nursing to work at the community level are also discussed and questions for reflection and debate raised.

Abstract
The correlations between heart-girths (measured as the smallest thoracic circumference) and liveweight were determined for 96 Saanen, 100 Angora and 101 feral female goats all of New Zealand origin. The correlation coefficients were 0.94, 0.94 and 0.90 for Saanens, Angoras and ferals respectively. To facilitate liveweight estimation for calculating doses of non-mineralised anthelmintics and to minimise under-dosing it is suggested that a straight-line equivalent of the upper 95% confidence curve be used. Care should be exercised in using girth measurements in small animals where the error could be high. They are not recommended for use when mineralised drenches or potentially dangerous drugs are being administered.

Abstract
Three approaches to changing lifestyle behaviours are hypothesized. The argument that diagnostic accuracy is essential for selection of appropriate nursing interventions is developed and illustrated with clinical examples. The diagnoses of information deficiency, information and behavioural control deficiency, and contextual awareness deficiency guide the interventions for the problem of obesity.

Abstract
In the health professions, questioning is traditionally viewed as a way of gathering information from a client as well as a way of developing the affective domain or how the client feels. The development of the cognitive domain, or how the client thinks, receives less attention. This article describes a clinical nursing approach using Bloom's Taxonomy to question clients' thinking behavior. Examples from nurses' files are used to clarify this approach.

Abstract
Selected nursing interventions for health promotion in well individuals are described. Over a two-year period, two clinical nurse specialists developed and used client record keeping, role playing, audio and video feedback, imagery, visual mapping and experimentation as health promotion interventions. Clinical examples and client outcomes are discussed. Health promoting interventions are clearly distinguished from disease prevention approaches as described in the literature.

Abstract
A plaque-forming lambdapolA phage was isolated from a population of transducing phage made in vitro from Escherichia coli DNA and a phage vector digested with restriction endonuclease HindIII. Amber mutations, in genes whose products are necessary for late protein synthesis (Q) and cell lysis (S), were crossed into the lambdapolA phage. Infection of either polA+ or polA- bacteria with this phage, under conditions permitting DNA replication but preventing phage production and lysis, elevated the levels of DNA polymerase I to between 75- and 100-fold that detected in a wild-type strain. The kinetics of enzyme production suggest that the polA gene is transcribed from its own promoter rather than from any of the well-characterized phage promoters. The fragment of E. coli DNA within the lambdapolA phage comprises approximately 5000 base pairs, sufficient to accommodate the polA gene and one, or two, coding sequences for smaller proteins.
