Multiple roles and women's mental and physical health: what have we learned?

Research on the effects of multiple roles on women's health has in the past been conducted within the context of two competing hypotheses: the scarcity hypothesis and the expansion hypothesis. Empirical evidence is more supportive of the expansion than the scarcity hypothesis, i.e., women who occupy several roles are healthier than those with few. However, this generalization obscures important health differentials related to types of roles occupied and attributes of those roles. Research on multiple roles is now shifting from examining numbers of roles to analyzing the effects of specific role combinations, patterns, and characteristics. Further research is needed to identify ways in which rewards and stresses within each role interact to produce health outcomes.

Fingertip number-writing errors by psychiatric patients.

Records from 495 psychiatric patients from two neuropsychology laboratories indicated the Fingertip Number Writing test shows a significant and reliable left-hand advantage within and between laboratories. While the left-hand advantage may reflect a right-hemisphere superiority for tactile-spatial processing, it is not possible to distinguish between right hemispheric functional superiority and practice effects between hands because the standard fingertip writing task always starts with the right hand.

Risk factors for myocardial infarction associated with the Chicago snowstorm of jan 13- 15, 1979.

Sixty male survivors of acute myocardial infarction in the week after the Chicago blizzard of Jan 15, 1979, were matched by hospital and sex with 60 myocardial infarction survivors from a week without snowfall to determine whether a history of previous heart disease or of cardiac risk factors increased the risk of a postblizzard myocardial infarction. Cases did not differ significantly from control subjects with respect to age, percentage working full time, or percentage with a history of heart disease, hypertension, smoking, diabetes mellitus, obesity, or gout. Hypercholesterolemia was four times as common among cases as among controls.

Reinforcement of vocal correlates of auditory hallucinations by auditory feedback: a case study.

Although auditory hallucinations in schizophrenic patients are usually thought to be private events, several early writers observed vocalizations concurrent with hallucinations. The content of such vocalizations corresponded to what the voices were reported to have said. A schizophrenic patient is described whose whispers were increased to an intelligible level by the use of auditory feedback. This has implications for the self-control of hallucinations, and for neurological theories of verbal hallucinations.

Individual differences in visual imaging and the voluntary control of heart rate.

The role of visual imagery in the bidirectional control of heart rate (HR) was explored in 24 subjects. While voluntary HR increases were reliably demonstrated with and without HR feedback, appropriate HR decreases were modest and inconsistent. Changes in respiration rate (RR) generally paralleled the alterations in HR. Eighteen of the subjects reported conventionally using visual imagery to effect HR changes. For these subjects, vividness of visual imagery scores and the extent of HR change showed indications of a direct relationship in the HR increase condition. However, in the HR decrease condition, it was concomitant RR changes which were associated with the vividness and the control of imagery production. The remaining six subjects, who reported not employing visual imagery, demonstrated superior HR acceleration to the imaging subjects. Further, while the imaging subjects did not benefit from the introduction of feedback, the six non-imaging subjects showed reliably greater HR acceleration as a result of feedback introduction.

Inflammatory cytology, infection and intraepithelial neoplasia.

The prognostic implications of minor grades of abnormality on cervical cytology are unclear. Women attending genitourinary medicine clinics who had cytology showing inflammatory changes with or without koilocytosis or borderline dyskaryosis have a high incidence of cervical intraepithelial neoplasia and genital infection. Of 119 patients who had a colposcopically directed cervical biopsy after one smear showing these changes, 46 (38%) had cervical intraepithelial neoplasia. Seventy-eight (57%) of 138 women had genital infection of whom 26 (33%) had a sexually transmitted disease. We recommend vigilant follow-up of borderline cytology including colposcopy if adequate facilities exist.

Antibody hyporesponsiveness in resistant BALB/cJ mice intracorneally infected with Pseudomonas aeruginosa.

Six- to eight-week-old BALB/cJ (and BALB/cPi) mice were found able to restore corneal clarity within 3 to 4 weeks after intracorneal infection with Pseudomonas aeruginosa strain 19660. However, enzyme-linked immunosorbent assay (ELISA) for serum immunoglobulins directed specifically against P. aeruginosa indicated that the mice were initially non- or hypo-responsive for IgG and IgA over the 4-week holding period. Low IgM titers could be detected 1 week after infection, but tended to decrease with time. When the mice were re-infected by using the contralateral control eye, then the serum IgG levels began to gradually increase as the time interval following the secondary infection increased from 1 to 3 weeks. Re-infected mice did not show a significantly increased rate of corneal clarity restoration with time, when compared to the corneas of mice receiving only a primary infection despite the presence of serum antibodies specific to P. aeruginosa. When congenic mice of the BALB/c background carrying the DBA/2N Idh/Pep-3 locus found on chromosome 1 were intracorneally infected, they tended to restore corneal clarity at approximately the same rate as the BALB/cJ mice. However, the congenic mice mounted a faster and substantially greater magnitude of serum IgM and IgG response during the primary infection than BALB/cJ mice receiving either a primary and/or secondary infection. IgG subclass studies with the congenic mice indicated that serum IgG1, and IgG2a to a lesser extent, were the primary immunoglobulins produced and no major shift in subclass was noted with time during the primary infection.(ABSTRACT TRUNCATED AT 250 WORDS)
