A survey of child care workers: Implications for administrators regarding job stress and satisfaction

Child care agencies in Ohio were surveyed concerning their programs and child care workers so as to better understand factors that contribute to job stress, attrition, and satisfaction. The survey provided data regarding the population served at the agencies and the characteristics of child care workers, their services, concerns, desires, and rewards. The findings indicate that environmental variables contribute largely to perceived concern and desired changes, whereas success with children provides a prominent source of job satisfaction.     

Sentinel surveillance of human immunodeficiency virus infection in women seeking reproductive health services in the United States, 1988-1989. The Field Services Branch.

Cases of AIDS among women of reproductive age have increased dramatically since 1981; nearly a third of all cases among females were reported in 1990 alone. Surveillance of human immunodeficiency virus (HIV) infection among women is essential for monitoring the spread of HIV over time and identifying specific populations and geographic areas in need of HIV counseling, testing, and prevention services. Blinded (unlinked) serologic surveys were conducted in the United States and Puerto Rico in sentinel clinics providing reproductive health services to women, including family planning, prenatal care, and abortion services. Seventy-eight of 94 clinics (83%) in 30 cities conducting surveys during 1988 and 1989 detected at least one HIV-positive woman. Clinic-specific prevalence ranged from 0-2.28% (median 0.22%), with rates over 1% occurring in clinics predominantly on the East Coast and in Puerto Rico. Seroprevalence varied by primary type of service, race-ethnicity, and age group. Median rates were higher in clinics offering prenatal services and lower in abortion and family planning clinics in the same cities. In general, women 25-29 years of age showed the highest median rate of infection (0.32%), and rates were higher among black women (median 0.34%) than among Hispanic (median 0.11%) and white women (median 0%). Our data indicate the need to educate women about recognizing and reducing their risk of HIV infection. Reproductive health clinics with high seroprevalence should implement voluntary HIV counseling and testing with appropriate follow-up clinical evaluation and referral for infected women. Clinics with low prevalence should seize the opportunity to enhance HIV education and prevention efforts.     

Tear plasmin activity with contact lens wear.

Plasmin, a proteolytic enzyme, has been detected in the tears of patients experiencing anterior ocular disease, and during contact lens wear. Using a radial caseinolysis procedure, we examined tear plasmin levels in 66 patients who were wearing soft and rigid lenses for daily and extended wear. Compared to non-contact lens wearers, patients wearing soft and rigid lenses for extended wear were significantly more likely to exhibit tear plasmin activity. Eight hours of open-eye thick HEMA lens wear did not induce tear plasmin activity in a group of 10 subjects. However, significant increases in tear plasmin activity were recorded after short-term (1 hour) eye closure with and without lens wear, and following overnight (8 hours) eye closure without lens wear. Overnight eye closure also resulted in significantly increased numbers of epithelial cells and leucocytes in the tear fluid. Our results suggest that increased tear plasmin activity during extended contact lens wear may be attributable to the effects of eye closure rather than hypoxia or the presence of the contact lens per se.     

Early Teenage Substance Use as a Predictor of Educational-Vocational Failure

The authors report on the relationship of early adolescent substance use (up to the time of the 16th birthday) to educational-vocational performance in the early adulthood of 612 African-American urban subjects. Voluminous prospective data were available on the behavior, test performance, and families of 612 urban African-American subjects, from birth up to 7 years of age. Scarcer prospective data were available for school performance during later years of school. Control variables were derived from these data to determine the amount of variance in each dependent educational-vocational outcome variable that was accounted for, independently of the amount of variance accounted for by early substance use.

Construction and validation of a Parkinson's disease mutation genotyping array for the Parkin gene.

Parkin mutations account for the majority of familial and sporadic early onset Parkinson's disease (EOPD) cases with a known genetic association. More than 100 mutations have been described in the Parkin gene that includes homozygous, compound heterozygous, and single heterozygous mutations. We have designed a Parkin mutation genotyping array (gene chip) that includes published Parkin sequence variants and allows their simultaneous detection. The chip was validated by screening 85 PD cases and 47 controls previously tested for Parkin mutations. Similar genotyping microarrays have been developed for other genetically heterogeneous diseases including age-related macular degeneration. Here, we show the utility of a genotyping array for Parkinson's disease by analysis of 60 subjects from the Genetic Epidemiology of Parkinson Disease (GEPD) study that includes 15 early-onset PD case probands and 45 relatives.
