Family medical leave. An employee benefit for working caregivers of elderly family members.

Future trends include a decrease in the number of adult children, an increase in the number of individuals over age 65, single parent families, working women, and individuals with no health care insurance. As more women with multiple roles and responsibilities enter and continue as part of the work force, employers recognize the need for support of family issues. Currently many employers lack initiative to make these needed changes. The occupational health nurses' role in relation to future policy for working caregivers includes assessment of how employment and caregiving impact work performance, job satisfaction, and health; and participation in defining public policy issues.

The complete nucleotide sequence of enterovirus type 70: relationships with other members of the picornaviridae.

Enterovirus type 70 (EV70) is the causative agent of acute haemorrhagic conjunctivitis and may also give rise to a rare neurological complication closely resembling poliomyelitis. The complete nucleotide sequence of the genome of EV70 has been determined from cDNA cloned in Escherichia coli. The genome consists of a 5' non-coding region of 726 nucleotides (nt), a long open reading frame of 6582 nt and a 3' non-coding region of 82 nt prior to the poly(A) tract. Comparison of the nucleotide sequence and the predicted amino acid sequence of the polyprotein with those published for other enteroviruses reveals sufficiently high similarity to predict antigenic regions and polyprotein cleavage sites. The P1 region of EV70 is as similar to those of the entero- as to those of the rhinoviruses, whereas the P2 and P3 regions are more closely related to the coxsackie B and swine vesicular disease viruses than other entero- or rhinoviruses.

Relationship of contractile state to ejection performance in patients with chronic aortic valve disease.

To assess the relative contributions of afterload mismatch and impaired contractility to pump dysfunction in patients with chronic aortic valve disease, simultaneous left ventricular cineangiography and micromanometry were performed in 56 patients: 21 with severe aortic stenosis, 16 with severe aortic regurgitation, and 19 normal control subjects. Left ventricular mass was increased in patients with aortic stenosis and aortic regurgitation (172 +/- 52 and 224 +/- 63 g/m2, respectively, vs 89 +/- 16 for control subjects; p less than .05) as were end-diastolic volume (101 +/- 39 and 167 +/- 44 vs 77 +/- 16 ml/m2; p less than .05) and end-systolic volume (50 +/- 40 and 84 +/- 43 vs 24 +/- 7 ml/m2; p less than .05). Although ejection fraction was depressed in both abnormal groups (0.56 +/- 0.18 for patients with aortic stenosis and 0.53 +/- 0.13 for those with aortic regurgitation vs 0.69 +/- 0.05 for control subjects; p less than .05), the decrease in ejection fraction was disproportionate to the mild degree of afterload mismatch (end ejection stress 129 +/- 17 in patients with aortic stenosis and 154 +/- 58 in those with aortic regurgitation vs 117 +/- 46 kdyn/cm2 in control subjects; p = NS) with 10 of 21 patients with aortic stenosis and 12 of 16 patients with aortic regurgitation falling below the 95% prediction limit of the linear inverse relationship between ejection fraction and end-systolic stress for controls (EF = 0.78 - 0.00074 X ESS).(ABSTRACT TRUNCATED AT 250 WORDS)

Enhancement of cardiac allografts in rats. Comparison of host responses to different treatment protocols.

Immunological responses to heterotopic (L X BN)F1 cardiac allografts placed in untreated L rats were compared with those grafts enhanced by different treatment regimens. Host pretreatment by antigen and antibody (Ag-Ab) 11 and 10 days before transplantation, respectively, was the most effective treatment regimen for prolongation of graft function; active or passive immunization alone increased survival only modestly. A late dose of antiserum administered to Ag-Ab-pretreated animals significantly shortened graft survival. Patterns of cellular responsiveness were measured serially by lymphocyte-mediated cytotoxicity; humoral immunity by Ab-lymphocyte-mediated cytotoxicity, capillary hemagglutination, and complement-dependent cytotoxicity. Allograft rejection in animals of all groups was heralded in vitro by increasing immunological activity. All cellular and humoral responses were depressed consistently in Ag-Ab-pretreated recipients. Cellular but not humoral responses were decreased in Ag-pretreated hosts, while humoral but not cellular responses were decreased in Ab-treated animals. The results suggest that the in vitro determinants of immunological activity used in this study generally followed clinical patterns of rejection or enhancement of cardiac allografts in the rat. Recipient pretreatment with Ag and Ab is more effective in graft prolongation than treatment with Ag or Ab alone, and in vitro data suggest an additive effect of these two regiments.

Oligonucleotide probes to identify three sibling species of the Anopheles farauti Laveran complex (Diptera: Culicidae).

We have sequenced recombinant plasmid probes for each of 3 Anopheles farauti complex species and identified internal oligonucleotides of 25-26 base pairs, specific for each member of the complex. Synthetic oligonucleotides oAf1, oAf2 and oAf3, when radiolabelled and hybridized with deoxyribonucleic acid from An. farauti, reacted as highly specific probes for An. farauti numbers 1, 2 and 3 respectively. These probes are effective on air-dried or alcohol-preserved larval, pupal or adult specimens.

Clinical cheating and moral development.

Clinical cheating is one of the most devastating ways students can breach moral principles, and its prevention should be a priority for nurse educators. Educators can promote the professional integrity of students by integrating moral development into all curricular efforts.
