RESUMO

Background: Immune system activation in the neonatal period is associated with white matter injury in preterm infants. In animal studies, neonatal priming of the immune system leads to chronic activation of i.e. microglia cells and altered neuroinflammatory responses potentially years after preterm birth. This may contribute further to brain injury and neurodevelopmental impairment. It is unknown to what extend this also occurs in human. Aim: To identify neuro-inflammatory markers at school age that relate to motor, cognitive and behavioral impairments in preterm born children in a pilot case-control study. Methods: We included n = 20 preterm born children (GA < 28 weeks) in this study, of which n = 10 with motor, cognitive and behavorial impairments and n = 10 preterm born controls next to n = 30 healthy adult controls. In the preterm children, at 8-9 years, 39 inflammatory markers were assessed by Luminex assay in blood serum samples. Firstly, the preterm concentrations of these markers were compared to n = 30 adult controls. Then a univariate analysis was performed to determine differences in values between preterm children with and without impairment at school age. Finally, a principal component analysis and hierarchical clustering was performed to identify protein profiles in preterm born children that relate to impairment at school age. Results: Inflammatory proteins in preterm children at school age differed from values of adult controls. Within the group of preterm children, we found significantly higher levels of GM-CSF in preterms with impairment (p < 0.01) and a trend towards significance for Gal1 and TRAIL (p = 0.06 and p = 0.06 respectively) when compared to preterms without impairment. In addition, differences in clustering of proteins between preterm children was observed, however this variance was not explained by presence of neurodevelopmental impairments. Conclusion: The inflammatory profile at school age in preterm children is different from that of adult controls. The immune modulating cytokines GM-CSF, Gal1 and TRAIL were higher in preterm children with impairment than control preterm children, suggesting that immune responses are altered in these children. No specific cluster of inflammatory markers could be identified. Results indicate that even at school age, neuroinflammatory pathways are activated in preterm born children with neurodevelopmental impairments.

RESUMO

The heterozygous Phospholamban p.Arg14del mutation is found in patients with dilated or arrhythmogenic cardiomyopathy. This mutation triggers cardiac contractile dysfunction and arrhythmogenesis by affecting intracellular Ca2+ dynamics. Little is known about the physiological processes preceding induced cardiomyopathy, which is characterized by sub-epicardial accumulation of fibrofatty tissue, and a specific drug treatment is currently lacking. Here, we address these issues using a knock-in Phospholamban p.Arg14del zebrafish model. Hearts from adult zebrafish with this mutation display age-related remodeling with sub-epicardial inflammation and fibrosis. Echocardiography reveals contractile variations before overt structural changes occur, which correlates at the cellular level with action potential duration alternans. These functional alterations are preceded by diminished Ca2+ transient amplitudes in embryonic hearts as well as an increase in diastolic Ca2+ level, slower Ca2+ transient decay and longer Ca2+ transients in cells of adult hearts. We find that istaroxime treatment ameliorates the in vivo Ca2+ dysregulation, rescues the cellular action potential duration alternans, while it improves cardiac relaxation. Thus, we present insight into the pathophysiology of Phospholamban p.Arg14del cardiomyopathy.

RESUMO

BACKGROUND: The aim of this study was to evaluate absolute mortality risks and to determine whether changes in mortality risk occurred in patients with intermittent claudication (IC) or critical limb ischaemia (CLI) in the Netherlands between 1998 and 2010. METHODS: Data for patients treated between 1998 and 2010 were obtained from Dutch nationwide registers: the Hospital Discharge Register, Population Register and Cause of Death Register. The registers were used to obtain information regarding IC and CLI hospitalizations, co-morbidities, demographic factors, and date and cause of death. The cohort was split into two time intervals for comparison: 1998-2004 (period 1) and 2005-2010 (period 2). Thirty-day mortality was excluded to eliminate per-admission complications. One- and 5-year cardiovascular and all-cause mortality rates were compared with those of a representative sample of the general Dutch population (28 494 persons) by Cox proportional hazards models. RESULTS: Some 47 548 patients were included, 34 078 with IC and 13 470 with CLI. In patients with IC, the age-adjusted 5-year mortality risk for cardiovascular disease decreased significantly in period 2 (14·1 per cent) compared with that in period 1 (16·1 per cent) in men only (5-year adjusted hazard ratio (HR) 0·76, 95 per cent c.i. 0·69 to 0·83; P < 0·001). In patients with CLI, the cardiovascular mortality risk decreased significantly only in women, with the 5-year risk reducing from 31·2 per cent in period 1 to 29·2 per cent in period 2 (adjusted HR 0·84, 0·74 to 0·94; P = 0·004). Compared with the general population, the mortality risk in patients with IC was increased between 1·70 (1·58 to 1·83) and 3·20 (2·69 to 3·81) times, and in those with CLI the risk was increased between 2·24 (2·09 to 2·40) and 5·19 (4·30 to 6·26) times. CONCLUSION: The risk of premature death in patients with IC and CLI declined significantly in the Netherlands, in a sex-specific manner, over the period from 1998 to 2010. The absolute risk of cardiovascular mortality remains high in these patients.

RESUMO

BACKGROUND: Favourable trends in risk factor levels in the general population may partly explain the decline in coronary heart disease (CHD) morbidity and mortality. Our aim was to present long-term national trends in established risk factors for CHD. METHODS: Data were obtained from five data sources including several large scale population based surveys, cohort studies and general practitioner registers between 1988 and 2012. We applied linear regression models to age-standardized time trends to test for statistical significant trends. Analyses were stratified by sex and age (younger <65 and older ≥65 years adults). RESULTS: The results demonstrated favourable trends in smoking (except in older women) and physical activity (except in older men). Unfavourable trends were found for body mass index (BMI) and diabetes mellitus prevalence. Although systolic blood pressure (SBP) and total cholesterol trends were favourable for older persons, SBP and total cholesterol remained stable in younger persons. CONCLUSIONS: Four out of six risk factors for CHD showed a favourable or stable trend. The rise in diabetes mellitus and BMI is worrying with respect to CHD morbidity and mortality.

RESUMO

INTRODUCTION: Therapeutic hypothermia improves outcome after perinatal asphyxia. The Ages and Stages Questionnaire is a screening tool to detect neurodevelopmental delay. In this study we examined the outcome of patients with perinatal asphyxia (defined as Apgar score <5 at 10 min, or continued need for resuscitation, or pH < 7.00 in umbilical cord or within one hour after birth) with and without therapeutic hypothermia treatment at the age of four years. METHODS: Cohort study of patients with perinatal asphyxia admitted to the Neonatal Intensive Care Units of the VU University Medical Center, Amsterdam and the Wilhelmina Children's Hospital, Utrecht in the year 2008. Parents were asked to fill out the 48 months Ages and Stages Questionnaire (ASQ). In Wilhelmina Children's Hospital treatment with therapeutic hypothermia was implemented in 2008, in the VU University Medical Center in 2009, providing a historical cohort. RESULTS/DISCUSSION: Twenty-three questionnaires were evaluated. Response rate of questionnaires for the VU Medical Center was 63% (n = 10) and Wilhelmina's Childrens Hospital 93% (n = 13). No significant differences were found in the mean scores between both groups. However, the untreated group scored more frequently under the -2 SD threshold. In the fine motor skills domain the difference was statistically significant (p = 0.031). In the treated group no patients developed cerebral palsy and in the untreated group two patients developed cerebral palsy. CONCLUSION: In this study patients treated with hypothermia tend to have a better neurodevelopmental outcome. No significant differences were found between the two groups, apart from the fine motor skills.

RESUMO

BACKGROUND/AIMS: Dietary management is a difficult but key aspect of care in children with Prader-Willi syndrome (PWS). We therefore investigated the effect of growth hormone (GH) treatment on reported energy intake in children with PWS, in relation with body composition, resting energy expenditure (REE) and hormone levels. METHODS: In a randomized controlled GH trial including 47 children with PWS, we assessed 5-day dietary records and dual-energy X-ray absorptiometry for body composition. REE was calculated by Müller's equation, based on fat mass, fat free mass and gender. RESULTS: Baseline energy intake of children with PWS was lower than normal daily energy requirements (p < 0.001), and decreased with age to 50% in prepubertal children. Energy intake in infants [m/f: 11/8; median (interquartile range [IQR]) age 2.7 years (1.5-3.2)] increased after 1 year of GH treatment (p = 0.008); this tended to be higher in the GH group than in the untreated group (p = 0.07). In prepubertal children [m/f: 14/14; median (IQR) age 6.8 years (5.1-8.1)], the increase in energy intake was higher in the GH group, but this was not different compared to the untreated group. REE was not different between the GH group and the untreated group. Increase in energy intake during 2 years of GH treatment was correlated with lower fat percentage standard deviation scores (p = 0.037) and higher adiponectin levels (p = 0.007). CONCLUSION: Our study demonstrates that parents of children with PWS are very well capable of restricting energy intake up to 50% compared to daily energy requirements for age- and sex-matched healthy children. GH treatment was associated with a slight increase in energy intake, but also improved body composition and adiponectin levels, which suggests a protective effect of GH treatment.

RESUMO

AIMS: In previous decades, a steep decline in acute myocardial infarction (AMI) incidence occurred in Western countries. We assessed whether this decline was also present in migrant groups living in the Netherlands. METHODS AND RESULTS: Nationwide registers were linked between 1998 and 2007. Poisson regression analyses were used to calculate the biannual percentage change in AMI incidence within major non-Western migrant groups, and the differences in these changes with the Dutch majority population. Within the Dutch majority population, AMI incidence significantly declined in men (-12%) and women (-9.5%). Incidence also declined among most migrant groups under study, ranging from -12 to -4.0% in men, and from -16 to -9.5% in women. Only in Turkish women and Moroccan men the AMI incidence remained stable over time (-0.3 and 2.8%, respectively). There were no statistically significant trend differences between the Dutch majority population and the migrant groups under study. The higher AMI incidence in Turkish men and Surinamese men and women, and the lower AMI incidence in Moroccan men persisted over time. CONCLUSIONS: There was a declining AMI incidence rate within the Dutch majority population as well as within most of the major migrant groups living in the Netherlands, except in Turkish women and Moroccan men. Trend patterns among migrant groups did not significantly differ from the Dutch majority population. To reduce ethnic inequalities, primary preventive strategies should be targeted at those migrant groups with a persisting higher incidence.

RESUMO

BACKGROUND: Preterm infants with progressive post-hemorrhagic ventricular dilatation (PHVD) in the absence of associated parenchymal lesions may have a normal neurodevelopmental outcome. OBJECTIVES: To evaluate neurodevelopmental and cognitive outcomes among preterm infants with severe intraventricular hemorrhage (IVH) and PHVD requiring neurosurgical intervention. METHODS: 32 preterm infants were admitted to a neonatal intensive care unit with PHVD requiring neurosurgical intervention, and were seen in the follow-up clinic for standardized cognitive, behavioral and neurological assessments between 5 and 8 years of age. Only preterm infants with a gestational age (GA) of <30 weeks, as well as preterm and full-term infants with PHVD and full-term infants with perinatal asphyxia are seen in our follow-up clinic at this age. There were 23 infants with a GA of <30 weeks in this study population. For these 23, matched controls were available and compared with the IVH group. RESULTS: The majority (59.4%) had no impairments. None of the children with grade III and 8 of the 15 children (53%) with grade IV hemorrhage developed cerebral palsy. More subtle motor problems assessed with the Movement-ABC score were seen in 39% (n = 9); the mean IQ of all children was 93.4, and 29% of the children had an IQ of <85 (-1 SD). Timing of intervention did not have a beneficial effect on outcome. With respect to cognition, no significant differences were found between the IVH and the control group. CONCLUSION: The majority of the children in our population had no impairments. Cerebral palsy was not seen in any of the infants with a grade III hemorrhage.

RESUMO

BACKGROUND: Extremely low birth weight (ELBW) infants are at risk of impaired postnatal growth. Impaired postnatal growth has been reported to be associated with delayed cognitive and motor development. AIMS: To describe postnatal growth patterns of appropriate and small for gestational age (AGA and SGA) ELBW children in relation to their cognitive and motor outcome at age 5.5. STUDY DESIGN: Retrospective cohort study. SUBJECTS: One hundred one children with a BW ≤ 750g, born between 1996 and 2005 in the University Hospital Utrecht, The Netherlands. OUTCOME MEASURES: Height (Ht), weight (Wt), occipital-frontal circumference (OFC) at birth, 15 months and 2 years corrected age and 3.5 and 5.5 years. Cognitive and motor outcome at 5.5 years of age, classified as normal (Z-score ≥-1), mildly delayed (-2≤Z-score <-1) or severely delayed (Z-score <-2). AGA (Ht, Wt or OFC at birth ≥-2 SDS) infants were compared with SGA (Ht, Wt or OFC at birth <-2 SDS) infants. RESULTS: Between birth and 5.5 years catch-up growth in Ht, weight for height (Wt/Ht), Wt and OFC was seen in 72.2%, 55.2%, 28.6% and 68.9% respectively of the SGA infants. For AGA infants we found substantial catch-down growth in Ht (15.4%) and Wt (33.8%). Cognitive and motor outcome was normal in 76.2% and 41.6% of the 101 children. A significantly higher percentage of normal cognitive outcome was found in AGA infants with Wt growth remaining at ≥-2 SDS compared to AGA infants with catch-down growth (83% vs 63%). Next, SGA infants who caught-up in OFC had a higher prevalence of normal cognitive outcome compared to SGA infants who did not catch-up in OFC. Furthermore, a higher percentage of severely delayed motor outcome was found in SGA infants without catch-up growth in Wt compared to SGA infants who caught-up in Wt (61.5% vs 32.2%). CONCLUSIONS: Catch-up growth in Ht, Wt/Ht and OFC occurred in the majority of the SGA infants with a BW ≤ 750 g, but was less common in Wt. AGA children who remained their Wt at ≥-2 SDS have a better cognitive and motor developmental outcome at 5.5 years of age. Catch-up growth in OFC was associated with a better cognitive outcome at 5.5 years of age.

RESUMO

BACKGROUND: Extremely low birth weight (ELBW) infants are at risk of cognitive impairment and follow-up is therefore of major importance. The age at which their neurodevelopmental outcome (NDO) can reliably be predicted differs in the literature. AIMS: To describe NDO at 2, 3.5 and 5.5 years in an ELBW cohort. To examine the value of NDO at 2 years corrected age (CA) for prediction of NDO at 3.5 and 5.5 years. STUDY DESIGN: A retrospective cross-sectional and longitudinal cohort study. SUBJECTS: 101 children with a BW≤750 g, born between 1996 and 2005, who survived NICU admission and were included in a follow-up program. OUTCOME MEASURES: NDO, measured with different tests for general development and intelligence, depending on age of assessment and classified as normal (Z-score≥-1), mildly delayed (-2≤Z-score<-1) or severely delayed (Z-score<-2). RESULTS: At 2, 3.5 and 5.5 years 74.3, 82.2 and 76.2% had a normal NDO. A normal NDO at 2 years CA predicted a normal NDO at 3.5 and 5.5 years in 92% and 84% respectively. Of the children with a mildly or severely delayed NDO at 2 years CA the majority showed an improved NDO at 3.5 (69.2%) and 5.5 years (65.4%) respectively. CONCLUSIONS: The majority of the children with a BW≤750 g had a normal NDO at all ages. A normal NDO at 2 years CA is a good predictor for normal outcome at 3.5 and 5.5 years, whereas a delayed NDO at 2 years CA is subject to change with the majority of the children showing a better NDO at 3.5 and 5.5 years.

RESUMO

OBJECTIVES: To describe 2-year neurodevelopmental outcome (NDO) in a cohort of extremely low birthweight infants, and compare NDO between two consecutive 5-year periods and between appropriate (AGA, ≥p10) and small for gestational age (SGA, -1 Z score ≤-2) or severely delayed (Z score >-2). RESULTS: 74.3% of the children had a normal NDO at 2 years corrected age, 20.8% a mildly and 5% a severely delayed outcome. Although survival significantly increased with time (65.8% to 88.1%, p=0.002), significantly fewer children in cohort II (66.1% vs 84.4% in cohort I, p=0.042) as well as fewer SGA children (64.3% vs 86.7% of AGA children, p=0.012) had a normal NDO. CONCLUSIONS: Increased survival of infants with a birth weight ≤750 g coincided with more children with an impaired NDO at 2 years corrected age. SGA infants are especially at risk of impaired NDO.

RESUMO

OBJECTIVE: To describe the individual intrauterine growth patterns of fetuses of insulin-dependent (Type-1) diabetic women and to examine determinants of overgrowth (macrosomia) and its timing. METHODS: This retrospective longitudinal study examined the developmental trajectories of fetal abdominal circumference (AC) and biparietal diameter in 76 Type-1 diabetic women with singleton pregnancies. Latent class analysis was used to identify subgroups of patients with a shared fetal AC growth trajectory. Subsequently, maternal factors, including glycemic control as assessed by glycosylated hemoglobin (HbA1c), were examined to see whether they had any effect on fetal growth. RESULTS: Four subgroups with different AC growth patterns were identified. Differences in birth weight between the distinct subgroups were related to the shape of the AC growth velocity curve over gestation. Acceleration of AC growth commencing before or after 25 weeks' gestation was associated with the birth of a heavy or large-for-dates baby in 94 and 56% of cases, respectively. Poor glycemic control (HbA1c > 7.0%) during the periconception period or before 12 weeks' gestation was a modest predictor of midtrimester growth in AC. Other diabetes-related factors, fetal sex, parity, or maternal weight/obesity were unrelated to the fetal growth pattern. CONCLUSION: The findings suggest that an individual fetus's growth trajectory is set early in gestation and that the contemporaneous degree of maternal glycemia plays a role in determining birth weight.

RESUMO

STUDY DESIGN: Cross-sectional analysis of individual interviews with a convenience sample of persons living with tetraplegia. OBJECTIVES: To describe patterns of residence among persons living with tetraplegia following discharge from initial acute medical care after spinal cord injury, decision-making process for each residence move and quality of life determinants at different residence types. SETTING: California and Minnesota, United States. METHODS: A total of 22 adults with traumatic spinal cord injury tetraplegia were interviewed about their residence histories, the residence decision-making process for each move, and positive and negative features at each residence at which they had lived. RESULTS: Information, money, insurance, accessibility, intimate relationships and personal assistants had the strongest influence over residence location, with insufficient information and finances demonstrating particularly strong influences. Participants frequently viewed parents' homes as an 'only option,' 'place of refuge' or 'stunting' environment. They viewed own homes as 'only options' or ways to achieve quality of life improvements, and other institutions as 'only options' or 'stepping-stones' to independent living. CONCLUSION: Further research is needed to examine decision-making across multiple moves over the course of the lives of persons living with tetraplegia, particularly examining the roles of inadequate information and finances as inhibitors of freedom of choice.

RESUMO

Considerable evidence suggests that people with HIV disease are significantly more distressed than the general population, yet psychiatric disorders are commonly under-detected in HIV care settings. This study examines the prevalence of three stress-related psychiatric diagnoses--depression, posttraumatic stress disorder (PTSD), and acute stress disorder (ASD), among a vulnerable population of HIV-infected patients. Among approximately 350 patients attending two county-based HIV primary care clinics, 210 participants were screened for diagnostic symptom criteria for depression, PTSD, and ASD. Standardized screening measures used to assess for these disorders included the Beck Depression Inventory, the Posttraumatic Stress Checklist, and the Stanford Acute Stress Questionnaire. High percentages of HIV-infected patients met screening criteria for depression (38 per cent), PTSD (34 per cent), and ASD (43 per cent). Thirty eight percent screened positively for two or more disorders. Women were more likely to meet symptom criteria for ASD than men (55 per cent vs. 38 per cent, OR=1.94, CI95 per cent=1.1-3.5). ASD was detected more commonly among African-American and white participants (51 per cent and 50 per cent respectively), compared with other ethnic groups. Latinos were least likely to express symptoms of ASD (OR=0.52, CI95 per cent=0.29-0.96). Of the 118 patients with at least one of these disorders, 51 (43 per cent) reported receiving no concurrent mental health treatment. Patients with HIV/AIDS who receive public healthcare are likely to have high rates of acute and posttraumatic stress disorders and depression. These data suggest that current clinical practices could be improved with the use of appropriate tools and procedures to screen and diagnose mental health disorders in populations with HIV/AIDS.

RESUMO

This study examined self-efficacy, coping, and social support in relation to difficulties interacting with physicians and nurses among women living with breast cancer. One hundred women living in rural, mountainous communities of northeastern California were recruited, with 89 providing complete data for this study. All women completed a battery of questionnaires that included the CARES--Medical Interaction Subscale and measures of self-efficacy, coping, satisfaction with social support, and demographic and medical characteristics. In a multiple regression analysis, difficulties interacting with medical professionals were found to be greater among women who were not married, who used more behavioral disengagement or less self-distraction to cope with breast cancer, and who reported less self-efficacy for affect regulation and for seeking and understanding medical information. Emotional venting and satisfaction with social support for dealing with cancer-related stress were not, however, significantly related to difficulties in interacting with the medical team. This model accounted for an adjusted value of 42% of the variance. Further research is needed to identify possible causal relationships related to these findings and to determine what interventions might be warranted to improve medical interactions for women with breast cancer living in rural areas.

RESUMO

This study examined the effect of sexual revictimization on information processing of trauma-related stimuli in a sample of child sexual abuse (CSA) survivors diagnosed with posttraumatic stress disorder (PTSD). Fifty-one treatment-seeking women participated in this study. Participants completed the Sexual Experiences Survey regarding sexual revictimization in the last 6 months and performed a modified emotional Stroop task in which they named the colors of neutral words (e.g., apple), general threat words (e.g., malignant and death), and sexual/victimization words (e.g., penis and abuser). As predicted, the revictimized participants (n = 16) took significantly longer to color-name sexual/victimization words than did the nonrevictimized participants. These results suggest that revictimization serves to prime preexisting "trauma" memory networks, thereby amplifying the impact of childhood sexual trauma on selective attention toward trauma-related stimuli.

RESUMO

BACKGROUND: Adherence is a major problem facing HIV-seropositive patients. Low adherence has been associated with faster disease progression as well as development of drug-resistant strains of HIV. Thus it is critical to understand factors associated with treatment compliance. This study examined the independent contributions of disease severity, age, gender, household income, homelessness, ethnicity, and sexual orientation on appointment adherence. METHODS: Participants (n = 671) scheduled for appointments in an outpatient county treatment facility for HIV-related medical care completed demographic questionnaires and clinic staff collected appointment attendance data. RESULTS: Multiple regression analyses indicated that patients diagnosed with AIDS, older in age, and receiving a higher income were more likely to keep medical appointments. Additionally, African American ethnicity and identifying as heterosexual were associated with missing scheduled medical appointments. CONCLUSIONS: These data suggest that cultural and sociodemographic characteristics influence patients' adherence to outpatient services. Implications for interventions aimed at increasing medical adherence are discussed.

RESUMO

BACKGROUND: Metastatic breast cancer carries with it considerable psychosocial morbidity. Studies have shown that some patients with metastatic breast cancer experience clinically significant anxiety and depression and traumatic stress symptoms. Supportive-expressive group psychotherapy was developed to help patients with cancer face and adjust to their existential concerns, express and manage disease-related emotions, increase social support, enhance relationships with family and physicians, and improve symptom control. METHODS: Of 125 women with metastatic breast cancer recruited into the study, 64 were randomized to the intervention and 61 to the control condition. Intervention women were offered 1 year of weekly supportive-expressive group therapy and educational materials. Control women received educational materials only. Participants were assessed at baseline and every 4 months during the first year. Data at baseline and from at least 1 assessment were collected from 102 participants during this 12-month period, and these participants compose the study population. RESULTS: Primary analyses based on all available data indicated that participants in the treatment condition showed a significantly greater decline in traumatic stress symptoms on the Impact of Event Scale (effect size, 0.25) compared with the control condition, but there was no difference in Profile of Mood States total mood disturbance. However, when the final assessment occurring within a year of death was removed, a secondary analysis showed a significantly greater decline in total mood disturbance (effect size, 0.25) and traumatic stress symptoms (effect size, 0.33) for the treatment condition compared with the control condition. CONCLUSION: Supportive-expressive therapy, with its emphasis on providing support and helping patients face and deal with their disease-related stress, can help reduce distress in patients with metastatic breast cancer.

RESUMO

This study examined distress, coping, and group support among a sample of rural women who had been recently diagnosed with breast cancer. We recruited 100 women who had been diagnosed with primary breast cancer at one of two time points in their medical treatment: either within a window up to 3 months after their diagnosis of breast cancer, or within 6 months after completing medical treatment for breast cancer. Their mean age was 58.6 years (SD = 11.6), and 90% were of white/European American ethnicity. Women completed a battery of demographic and psychosocial measures prior to being randomized into a psychoeducational intervention study, and then again 3 months later at a follow-up assessment. The focus of this article is on the women's self-reported psychosocial status at baseline. Many of the women experienced considerable traumatic stress regarding their breast cancer. However, this distress was not reflected in a standard measure of mood disturbance that is frequently used in intervention research (the Profile of Mood States). The average woman considered her diagnosis of breast cancer to be among the four most stressful life events that she had ever experienced. Also, women on average reported a high level of helplessness/hopelessness in coping with their cancer. On average, women felt that they "often" (but not "very often") received instrumental assistance, emotional support, and informational support. Women varied considerably in which kind of social group provided them with the most support, with as many reporting that they found the greatest support in spiritual/church groups or within their family units as with breast or general cancer groups. These results suggest that among these rural women with breast cancer, distress with the diagnosis of breast cancer must be carefully assessed, as women who are highly distressed about their breast cancer may not report general mood disturbance. Furthermore, the kinds of groups that rural women with breast cancer experience as most supportive need to be identified so that psychosocial interventions can be matched to breast cancer patients' individual needs.
