Improving the effectiveness of adjuvant psychological treatment for women with breast cancer: The feasibility of providing online support
Authors: Owen Jason E. , Klapow Joshua C. , Roth David L. , Nabell Lisle , Tucker Diane C. 
Published: March 2004

AbstractMany well‐designed studies have shown psychosocial treatments for cancer to be efficacious for improving patients' quality of life, but the actual impact of these treatments may be limited by low rates of participation. Web‐based treatment formats could improve effectiveness by increasing availability and accessibility. Two phases of a feasibility study are reported in this article. In the first phase, we sought to assess internet access and perceived interest in online support among 136 women with breast cancer (June–October, 1999). Levels of interest in participating in an online psychosocial treatment were associated with age, outcome expectancy, and barriers to using the internet but not stage or time since diagnosis. In the second phase, we document accrual rates among several methods of recruitment during a randomized trial (February–December, 2001) and report changes over time in internet access. Recruitment rates were substantially higher when a study representative was available in clinic to provide information about the treatment than for all other methods of recruitment. Access to the internet increased between 1999 (63%) and 2001 (70%) and varied across age groups. These results suggest that internet‐based psychosocial treatments, with notable limitations, are feasible for increasing the impact of psychosocial care. Copyright © 2003 John Wiley & Sons, Ltd.

Published: March 2004

AbstractObjectives: The objectives of this study are to identify the prevalence of depression and the accuracy of depression screening instruments in ambulatory head and neck cancer patients who have received radiation. This population is at risk for depression because of the life‐threatening nature of the illness, and treatment‐induced oral morbidity.Methods: Sixty subjects were evaluated for Major and Minor Depression according to Research Diagnostic Criteria using the Schedule for Affective Disorders and Schizophrenia (SADS). Screening instruments examined were the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS) and the Centre for Epidemiological Studies‐Depression (CES‐D) scale. Accuracy was assessed by calculating the sensitivities, specificities, positive predictive values (PPV) and areas under curve (AUC) from Receiver Operating Characteristic (ROC) curves.Results: The prevalence of Major and Minor Depression was 20%. All of the screening instruments tested were found to be highly accurate. Statistically significant differences between the instruments were not observed but the HADS demonstrated the highest absolute levels of sensitivity, specificity and PPV. No cases of Major Depression were missed by any of the instruments tested.Conclusions: These results suggest that a significant minority of head and neck cancer patients are depressed in the post radiation period, and that accurate screening for clinically significant depression is possible using any of the three instruments evaluated here.

Correlates of posttraumatic growth in husbands of breast cancer survivors
Authors: Weiss Tzipi 
Published: March 2004

AbstractFollowing breast cancer, many survivors and spouses report posttraumatic growth (PTG)—positive life changes. This correlational study identified social context and event‐related correlates of PTG among husbands of breast cancer survivors (N=72). Bivariate analyses indicated that husbands' PTG was positively associated with general social support, greater marital support and depth of commitment, greater PTG in wife, shorter time since diagnosis and breast cancer meeting DSM‐IV criteria for traumatic stressor. Multiple regression analysis revealed that the significant predictors of husbands' PTG were depth of marital commitment, wife's PTG, and breast cancer meeting DSM‐IV traumatic stressor criteria. Psychosocial research and interventions need to acknowledge that couples face the cancer together and share not only the pain but also the potential for gain from the trauma.

AbstractMany studies have reported that cancer patients who show difficulties maintaining perceptions of control report more psychological distress than patients who are higher in control. Besides perceptions of control, feelings of illness uncertainty have also been regarded as a predictor of psychological distress. Given these strong relationships between perceptions of low control and high illness uncertainty and psychological distress, the present study examined whether an informational self‐management intervention (booklet) could moderate this relationship. The booklet contained general and specific information about cancer and cancer treatment, information about possible coping strategies, and social comparison information, which consisted of short stories of other patients. Prior to radiotherapy, 209 patients with cancer completed baseline measures, including control and illness uncertainty. After completing radiotherapy, patients were randomly allocated to receive either a booklet (experimental group; N=103) or no booklet (control group; N=106). Three months after the intervention, aspects of psychological distress were assessed, including tension, anger, depression, fatigue and vigour. The results supported our hypotheses and suggested that a self‐management intervention is relevant in reducing the relationship between control and illness uncertainty before radiotherapy and psychological distress after radiotherapy. This seems important, especially for high‐risk patients who perceive little control and much illness uncertainty. Copyright © 2003 John Wiley & Sons, Ltd.
The vertex degree distribution of random intersection graphs
Authors: Stark Dudley 
Published: March 2004

AbstractRandom intersection graphs are a model of random graphs in which each vertex is assigned a subset of a set of objects independently and two vertices are adjacent if their assigned subsets are not disjoint. The number of vertices is denoted by n and the number of objects is supposed to be ⌊nα⌋ for some α > 0. We determine the distribution of the degree of a typical vertex and show that it changes sharply between α > 1, α = 1, and α > 1. © 2004 Wiley Periodicals, Inc. Random Struct. Alg., 2004
The impact of maternal plasma volume expansion and antihypertensive treatment with intravenous dihydralazine on fetal and maternal hemodynamics during pre‐eclampsia: a clinical, echo‐Doppler and viscometric study

Published: March 2004

AbstractObjectivesTo establish the effects of plasma volume expansion (PVE) followed by intravenous dihydralazine (DH) administration on maternal whole blood viscosity (WBV) and hematocrit, uteroplacental and fetoplacental downstream impedance and umbilical venous (UV) volume flow in pre‐eclampsia.MethodsIn 13 pre‐eclamptic women maternal and fetal hemodynamics were established by means of combined measurement of maternal arterial blood pressure (BP), WBV, hematocrit and uterine artery (UtA) resistance index (RI) in addition to umbilical artery (UA) pulsatility index (PI) and UV volume flow obtained from UV vessel area and UV time‐averaged flow velocity. In each woman all parameters were measured four times at baseline, after PVE, after DH and 24 h after the start of treatment.ResultsMaternal diastolic BP, hematocrit and WBV display a significant reduction after PVE. In the fetus UA PI decreases significantly whereas a significant increase in UV cross‐sectional area was detected. After maternal DH administration, arterial systolic and diastolic BP and UA PI show a significant decrease compared with the measurements following PVE. At 24 h, only maternal systolic and diastolic BP display a significant further decrease. No significant changes were established for the UtA RI, UV time‐averaged velocity and UV volume flow during the entire study period.ConclusionsDuring pre‐eclampsia, maternal PVE followed by DH administration results in a significant reduction in maternal diastolic BP, maternal hematocrit and WBV. Maternal PVE is associated with a significant increase in UV cross‐sectional area and a non‐significant rise of 11% in UV volume flow. Maternal DH administration does not result in any change in UV cross‐sectional area. However, UA PI decreases significantly after both PVE and DH treatment. Copyright © 2004 ISUOG.

Published: March 2004

AbstractObjectivesTo evaluate whether fetal brain magnetic resonance imaging (MRI) adds useful clinical information to that obtained by dedicated fetal neurosonography using a combined transabdominal and transvaginal approach in fetuses with suspected brain anomalies.MethodsIn the 2‐year period between January 2000 and January 2002, 42 fetuses underwent neurosonographic and MRI examinations of the brain. The referral indications were: asymmetric ventriculomegaly (13), ventriculomegaly (7), periventricular cysts (2), suspected midline findings (7), agenesis of the corpus callosum (3), infratentorial pathology (3), cytomegalovirus (CMV) infection (2) and miscellaneous indications (5).ResultsNeurosonography and MRI produced similar diagnoses in 29 fetuses: normal examination (10), isolated asymmetric ventriculomegaly (11), isolated ventriculomegaly (3), periventricular cysts (2), agenesis of the corpus callosum (1), pericallosal lipoma (1) and cerebellar hemorrhage (1). The neurosonographic diagnoses were more accurate in seven patients: hemimegalencephaly, pericallosal lipoma, signs of CMV infection, brain anomalies associated with agenesis of the corpus callosum and three fetuses with a normal ultrasound scan in which MRI suggested a parenchymal abnormality. MRI provided a more accurate diagnosis in three patients: a third ventricular dilatation was ruled out, normal ventricles in a fetus with an ultrasonographic finding of asymmetric ventricles, and diagnosis of progression of asymmetric ventriculomegaly. In three patients the identified pathologies were differently interpreted, each examination provided another aspect of the anomaly or a definitive diagnosis was not possible.ConclusionsOur study demonstrated that dedicated neurosonography is equal to MRI in the diagnosis of fetal brain anomalies. In most of the cases MRI confirmed the ultrasonographic diagnosis; in a minority of cases each modality provided additional/different information. The major role of MRI was in reassurance of the parents regarding the presence or absence of brain anomalies. Copyright © 2004 ISUOG. Published by John Wiley & Sons, Ltd.

Published: March 2004

AbstractCytomegalovirus (CMV) is the most common cause of congenital infection worldwide. We report on a fatal fetal manifestation of primary maternal CMV infection including cerebellar hemorrhage and hydrops. The diagnosis was established by maternal serological tests, culture and polymerase chain reaction testing of amniotic fluid and fetal blood. The pregnancy was terminated. Postmortem examination confirmed the diagnosis. Copyright © 2004 ISUOG. Published by John Wiley & Sons, Ltd.

Published: March 2004

AbstractRhabdoid tumors of the kidney are highly lethal malignancies of infancy. We report the prenatal detection of a renal rhabdoid tumor with mesoblastic components in a fetus at 27 weeks of gestation. The tumor presented as a large mass in the left renal area and there was concomitant massive polyhydramnios. Though the sonographic features alone did not allow distinction from a benign lesion, the aggressive tumor growth indicated malignancy. Amniotic fluid cytology was performed but failed to confirm the diagnosis. Corticosteroids were administered for lung maturation. Tocolysis, including betamimetics, magnesium and indomethacin, was performed to prevent premature labor. Additionally, serial amniodrainage was performed. At 30 weeks of gestation fetal hydrops developed and a Cesarean section was performed. After delivery, ventilation of the preterm infant was insufficient due to diaphragm elevation by the huge tumor, requiring immediate tumor surgery. However, though ventilation was improved the infant died of cardiac failure 4 h after surgery. Copyright © 2004 ISUOG. Published by John Wiley & Sons, Ltd.

Published: March 2004

AbstractFetal cardiac defects leading to intrauterine cardiac failure and subsequent fetal hydrops are rare. We report an unusual case of a double‐chamber right ventricle leading to progressive fetal cardiac insufficiency and hydrops. The patient was first managed conservatively. Delivery by Cesarean section was performed for a pathological fetal heart‐rate tracing at 28 weeks of gestation. The newborn died 4 h postpartum due to generalized cardiac insufficiency.

Published: March 2004

AbstractObjectivesTo determine the prevalence of chromosomal abnormalities in fetuses with open neural tube defects (NTD) undergoing prenatal chromosome analysis. The role of prenatal ultrasound in detecting those with an underlying chromosomal abnormality was also investigated.MethodsOver a 6‐year period, 144 fetuses with open NTD underwent prenatal chromosome analysis between 12 and 37 weeks of gestation, as part of a prospective, multicenter prenatal diagnosis and counseling program in Chile. This population included 66 fetuses with spina bifida, 46 with acrania/anencephaly, 21 with cephalocele and 11 with iniencephaly. A confident prenatal diagnosis was made in 143 fetuses (99%) and confirmed postnatally in all cases.ResultsAn underlying chromosomal abnormality was diagnosed in 10 fetuses (7%), six with spina bifida, three with cephalocele and one with craniorachischisis. The prevalence of chromosomal abnormality varied according to the defect present in the fetus, with a 14% (3/21) prevalence among those with cephalocele, 9% (6/66) among those with spina bifida and 2% (1/57) among those with lethal defects such as acrania, anencephaly or iniencephaly. Karyotype results revealed trisomy 18 in seven cases, trisomy 13 in two and mosaicism for a marker chromosome in one. Prenatal ultrasound before the procedure showed that all chromosomally abnormal fetuses had additional findings. The prevalence of chromosomal abnormality in fetuses with spina bifida and cephalocele was higher when chromosome analysis was performed at or before 24 weeks of gestation in comparison to those performed after 24 weeks (5/31 (16%) vs. 4/56 (7%), respectively). However, this difference did not reach statistical significance, probably due to the small number of cases.ConclusionsA significant number of fetuses with open NTD are chromosomally abnormal. Although prenatal chromosome analysis should be considered in all cases, prenatal ultrasound seems effective in identifying those fetuses with an underlying chromosomal abnormality.

Published: March 2004

The deformation of the crust and fluid rock interactions are both important problems in the Earth sciences. Observing and measuring these coupled phenomena will improve our understanding of geologic processes acting in fractured porous media and the transfer properties of fluids. These observations can be made via laboratory experiments, but the sample scale is not always satisfying for understanding crustal‐scale phenomena.On the contrary, monitoring a natural site at the field‐scale provides clues that are directly interpretable in terms of geologic phenomena. The Roselend Experiment is one such endeavor that provides a setting for a multidisciplinary research project. Its goal is to determine transfer processes and transient phenomena at different scales in space and time within a highly dynamic system that is submitted to mechanical, hydrologic, meteorological, and thermal forces.
Climate reconstructions: Low‐frequency ambition and high‐frequency ratification
Authors: Esper Jan , Frank David C. , Wilson Robert J. S. 
Published: March 2004

The assessment of past temperature variations and the magnitude and characteristics of recent warmth relative to warm periods in pre‐industrial times—for example, during the Medieval Warm Period (MWP)—have critical implications for understanding and quantifying the forcing of climate in natural and anthropogenic conditions. The desire to benchmark past climate variability of the northern hemisphere has resulted in four millennial‐length temperature reconstructions with annual resolution [Briffa, 2000; Esper et al., 2002; Jones et al., 1998; Mann et al., 1999].These records, however, provide different perspectives on the above issues. For example, the temperature amplitude reconstructed by Esper et al. [2002] is about 1°C, approximately twice that of Mann et al. [1999] and Jones et al. [1998]. Additionally, Briffa [2000] and Esper et al. [2002] display a pronounced MWP followed by a significant 200‐300‐year‐long cooling trend associated with the Little Ice Age. Such a trend is broadly absent in Mann et al. [1999] and Jones et al. [1998].
Stable water usage, but some groundwater concerns, USGS report indicates

Published: March 2004

Water use in the United States has remained fairly stable since 1985, according to an 11 March report by the U.S. Geological Survey. The report, which estimates water use for the year 2000—the most recent available data—indicates that Americans used an estimated 408 billion gallons of water per day an amount the agency said would fill 8 billion bathtubs daily.This also translates into 1,430 gallons per person per day when including electric power generation, irrigation, and personal use.
“Comet‐chaser” spacecraft launched

Published: March 2004

The European Space Agency successfully launched its Rosetta spacecraft on 2 March, the beginning of what is hoped will be a 10‐year journey that will provide information about the origins of the solar system, by placing a lander on the nucleus of comet 67/P Churyumov‐Gerasimenko. Rosetta was launched from the ESAs facility at Kourou, French Guiana.After three flybys of the Earth and one of Mars, Rosetta is scheduled, in mid‐2011, to ignite its main engine for a major deep‐space maneuver that will place it onto an intercept trajectory with the comet.
Investigating the structural evolution of the western Baltic

Published: March 2004

The western Baltic Sea, located along the northern margin of the Central European Basin System (CEBS), is a world‐class site for investigating the dynamics and stratigraphic evolution of a continental basin with marine geophysical data acquisition techniques. The universities of Aarhus and Hamburg have joined forces to investigate the post‐Permianto‐recent structural evolution of the western Baltic, with special emphasis on neotectonic re‐activation along major structural lineaments.Deep crustal structures of the CEBS are well established from previous studies. However, no systematic and localized research has yet been carried out to investigate the neotectonic activity in this region. In fact, the limited seismic resolution of previously available data prevented detailed research on Mesozoic and Cenozoic evolution or neotectonics.

Published: March 2004

As part of the continuing effort to inform members about the publications program and get their input, the Publications Committee scheduled an open forum at the 2003 AGU Fall Meeting. This was to allow any members or guests the opportunity to ask questions about the AGU publications program, processes, progress, or any other publications‐related concerns. Here, we are using the pages of Eos to share several “good news” messages about AGU publications and open a dialogue with the membership about the publications program.The first thing to remember about AGU publications is that historically they have supported many of the non‐revenue generating activities of the Union that we hold to be important. Examples include workshops for high school teachers, career information for pre‐college students and school counselors, and information for the press and for decision‐makers at various levels of government. Publications are very important to the mission of AGU, both intellectually and financially (Figure 1).
Interaction Between Natural Killer and Dendritic Cells: the Role of CD40, CD80 and Major Histocompatibility Complex Class I Molecules in Cytotoxicity Induction and Interferon‐γ Production

AbstractThis study focuses on the differential role of CD40 and CD80 costimulatory molecules and major histocompatibility complex class I (MHC‐I) antigens in the regulation of the interplay between dendritic cells (DCs) and interleukin (IL)‐2‐activated human natural killer (NK) lymphocytes. Our data indicate that CD40 and CD80 molecules might play a preferential role in the induction of cytotoxic function but not in the interferon‐γ(IFN‐γ) production by human IL‐2‐activated NK effectors in the presence of autologous and allogeneic DCs. In addition, a critical role of CD94‐dependent MHC‐I recognition in the regulation of both IFN‐γ production and target cell lysis was shown in the functional interaction between NK and DCs.
