Comparison of lesbian and heterosexual women's response to newly diagnosed breast cancer.

In a study comparing lesbian and heterosexual women's response to newly diagnosed breast cancer, we compared data from 29 lesbians with 246 heterosexual women with breast cancer. Our hypotheses were that lesbian breast cancer patients would report higher scores of mood disturbance; suffer fewer problems with body image and sexual activity; show more expressiveness and cohesiveness and less conflict with their partners; would find social support from their partners and friends; and would have a poorer perception of the medical care system than heterosexual women. Our predictions regarding sexual orientation differences were supported for results regarding body image, social support, and medical care. There were no differences in mood, sexual activity or relational issues. Not predicted were differences in coping, indicating areas of emotional strength and vulnerability among the lesbian sample.

Revictimization and information processing in women survivors of childhood sexual abuse.

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.

Distress, coping, and social support among rural women recently diagnosed with primary breast cancer.

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.

Spiritual expression and immune status in women with metastatic breast cancer: an exploratory study.

This exploratory study examined relationships between spirituality and immune function in 112 women with metastatic breast cancer. Spirituality was assessed by patient reports of frequency of attendance at religious services and importance of religious or spiritual expression. White blood cell counts, absolute numbers of lymphocytes, T-lymphocyte subsets, and natural killer cells were assessed by flow cytometry. Assessments of natural killer cell activity and delayed-type hypersensitivity responses to skin test antigens provided two measures of functional immunity. In analyses controlling for demographic, disease status, and treatment variables, women who rated spiritual expression as more important had greater numbers of circulating white blood cells and total lymphocyte counts. Upon examination of relationships with lymphocyte subsets, both helper and cytotoxic T-cell counts were greater among women reporting greater spirituality.

Social support and salivary cortisol in women with metastatic breast cancer.

OBJECTIVE: This study used a cross-sectional design to examine the relationships between social support, both quantity (number of people) and quality (appraisal, belonging, tangible, and self-esteem), and neuroendocrine function (mean and slope of diurnal salivary cortisol) among women with metastatic breast cancer. METHODS: Participants (N = 103) were drawn from a study (N = 125) of the effects of group therapy on emotional adjustment and health in women with metastatic breast cancer. They completed the Interpersonal Support Evaluation List and the Yale Social Support Index and provided saliva samples for assessment of diurnal cortisol levels on each of 3 consecutive days. Diurnal mean levels were calculated using log-transformed cortisol concentrations, and the slope of diurnal cortisol variation was calculated by regression of log-transformed cortisol concentrations on sample collection time. RESULTS: Mean salivary cortisol was negatively related to the Interpersonal Support Evaluation List subscales of appraisal, belonging, and tangible social support. No association was found between quantitative support or the esteem subscale of the Interpersonal Support Evaluation List and mean salivary cortisol. Measures of qualitative and quantitative social support were not associated with the diurnal cortisol slope. CONCLUSIONS: Results show that greater quality of social support is associated with lower cortisol concentrations in women with metastatic breast cancer, which is indicative of healthier neuroendocrine functioning. These results may have clinical implications in the treatment of breast cancer.

Impaired vasoreactivity of the basilar artery system in patients with brainstem lacunar infarcts.

BACKGROUND AND PURPOSE: Diminished vasoreactivity (VR) has been evidenced in patients with hemispheric small vessel disease, however, there is no data regarding vertebrobasilar (VB) territory VR changes in patients with subcortical vascular encephalopathy located in the brainstem. Therefore, we compared the cerebral blood flow velocity (CBFV) responses of the VB system during different vasoregulatory challenges in healthy volunteers to those in patients with brainstem lacunar infarcts. METHODS: In 20 patients with brainstem lacunar infarcts and in 10 healthy volunteers the VR of the VB system was measured by analyzing the CBFV changes during different stimulation paradigms (ventilation, tilting and acetazolamide tests). During transcranial Doppler registration the systemic blood pressure and the expiratory partial CO2 pressure were monitored. RESULTS: During hypercapnia the VR was significantly higher in the control group than in the patient group (10.1 +/- 4.9 vs. 3.4 +/- 5.0 cm/s/kPa, p = 0.0025). In a subgroup of patients with mean baseline CBFV <25 cm/s the VR was 1.5 +/- 2.4 cm/ s/kPa, while patients with mean baseline CBFV >25 cm/s showed a significantly higher value (7.8 +/- 6.9 cm/s/kPa). Furthermore, in patients with mean baseline CBFV <25 cm/s the pulsatility index was significantly higher than in patients with mean baseline CBFV >25 cm/s (1.11 +/- 0.26 vs. 0.86 +/- 0.19, p = 0.0325), reflecting significantly higher vascular resistance in the former group. Although CBFV measurements during tilting and acetazolamide tests tended to support these findings, they showed no significant differences between patients and controls. CONCLUSION: Patients with cerebral microangiopathy involving the brainstem showed impaired VR in the VB flow territory in association with baseline CBFV.

Disciforme keratitis caused by Bartonella henselae: an unusual ocular complication in cat scratch disease.

Cat scratch disease (CSD) is a common infectious disease, however, its association with disciforme keratitis is a previously unreported ocular complication. With the use of the 16S rDNA-PCR technique with subsequent DANN sequencing on corneal material obtained by corneal scrape we were able to identify Bartonella henselae in an unusual form of disciforme keratitis.

Psychosocial influences on cancer incidence and progression.

The impact of psychosocial factors on the incidence and progression of cancer has become an area that demands attention. In this article recent evidence of psychosocial effects on cancer incidence and progression is reviewed in the context of past research. Psychosocial factors discussed include personality, depression, emotional expression, social support, and stress. Mechanisms that could mediate the relationship between psychosocial conditions and cancer incidence and progression are also reviewed. These include alterations in diet, exercise, and circadian cycles; variations in medical treatment received; and physiological mechanisms such as psychoendocrinologic and psychoneuroimmunologic effects. We conclude that there is a nonrandom relationship among various psychosocial factors and cancer incidence and progression that can only partially be explained by behavioral, structural, or biological factors. Suggestions for future research are discussed.
