Investigating stress effect patterns in hospital staff nurses: Results of a cluster analysis

A comprehensive and reliable assessment of work stress, burnout, affective, and physical symptomatology was conducted with 260 hospital nurses. As previous attempts to categorize nursing stress and burnout by ward type have yielded inconsistent results, an alternative method for grouping nursing stress effects was sought. Cluster analysis was chosen as it offers a statistically sound means of delineating natural groupings within data. Sets of questionnaires measuring burnout, work stressors, and physical and emotional symptomatology were sent to all staff nurses at a large university hospital. Of 709 nurses employed there, a total of 260 nurses returned completed questionnaire packets. These nurses were separated into two equal groups using random sampling procedures. Cluster analysis of this data revealed groupings which were based on nursing stressors (particularly workload and conflict with physicians), social support, and patient loads. These cluster-analytic findings were replicated on both samples, and validated using data not used in the original cluster analysis. Results suggest that the effects of stress have more to do with the characteristics of the work environment and overall workload than with the degree of specialization on the unit. Results also suggest that intraprofessional conflict (i.e. with other nurses) is less psychologically damaging than is interprofessional conflict (i.e. conflict with physicians). Findings are discussed with respect to the burnout process and possible interventions.     

In vivo induction of CD4+ T cell responses by antigens covalently linked to synthetic microspheres does not require adjuvant

Macrophages, dendritic cells or B lymphocytes have been shownto play a major role in the presentation of soluble antigensto CD4⁺ T cells. In contrast, the capacity of these cells topresent particulate antigens such as bacterial or parasiticantigens to T cells remains controversial. To investigate thisquestion, well defined particulate antigens were prepared bycovalent linkage of proteins or peptides to 1 µm in diametersynthetic microspheres. The T cell immunogenicity of such particulateantigens was analyzed in vitro and in vivo. In vitro, a solubleprotein such as hen egg lysozyme (HEL) coupled to beads stimulateda strong proliferative T cell response of lymph node cells fromHEL-primed mice or of specific T cell hybridomas. HEL coupledto beads was presented to the specific T cell hybridomas bysplenocytes or by peritoneal macrophages, but not by lymphomaB cells. Immunization of mice with several different proteinantigens or with a synthetic peptide covalently linked to beadsinduced strong CD4⁺ T cell responses in the absence of adjuvant.The strong in vivo immunogenicity of proteins coupled to beadsdid not result from a non-specific adjuvant effect of beadssince covalent linkage of the antigen to beads was strictlyrequired to induce T cell responses in the absence of adjuvant.In vivo treatment by carrageenan showed that macrophages arerequired for the in vivo stimulation of T cell responses bythese particulate antigens. Thus, these results demonstratedthe role of phagocytic cells, especially macrophages, for invivo presentation of particulate antigens. These particulateantigens represent an interesting approach for the developmentof new vaccines, and for the in vivo analysis of the role ofvarious antigen presenting cells in T cell activation and differentiation.     

FACTORS RELATED TO PERINEAL TRAUMA IN CHILDBIRTH

We conducted an observational cohort study in three nurse-midwifery services to identify patient characteristics and clinical care measures related to perineal trauma at birth. Data were collected on all women who began care with a nurse-midwife in labor, using an adaptation of the Nurse-Midwifery Clinical Data Set (n = 3,049). Study variables included demographics, perineal management techniques and position for birth, and other intrapartum care and events. Univariate and multivariate analyses showed that episiotomy was strongly related to fetal bradycardia, prolonged second stage, ethnic status, and maternal education level. Warm compresses and flexion/counterpressure to slow delivery were protective. Spontaneous lacerations were influenced by these factors as well. The lateral position for birth was protective, and use of oils or lubricants and the lithotomy position increased lacerations. Multisite studies in nurse-midwifery practices may provide an ideal means of determining effective care measures in healthy populations.     

Absent chondrodysplasia punctata in a male with an Xp terminal deletion involving the putative region for CDPX1 locus

This is a follow-up report on a male patient with a 46, Y, r(X) karyotype. Although he had no clinico-radiological features of X-linked recessive chondrodysplasia punctata (CDPX1), molecular studies revealed an Xp terminal deletion involving the putative region for the CDPX1 locus (PABX-DXS31). We suspect that the absence of CDPX1 may be attributable to the nature of the disease and the extreme short stature of the patient (mean – 5.6 S.D.). © 1993 Wiley-Liss, Inc.     

Akathisia as a side effect of antipsychotic treatment with quetiapine in a patient with Parkinson's disease.

Due to its low profile for extrapyramidal side-effects, quetiapine has become an alternative to clozapine in the treatment of dopamimetic psychosis in patients with Parkinson's disease (PD). We describe the case of a patient with PD who developed severe akathisia, a common complication with classical antipsychotics, with quetiapine.

The Future of Clinical Psychology: Board Certification

The present article presents the future of clinical psychology board certification. With the increasing specialization in the field of professional psychology and the generic nature of state licensure, clinical psychology as a specialty will develop into a specialty area in a similar fashion as have specialties in medicine. A brief history of board certification in professional psychology by the American Board of Professional Psychology is reviewed and the process of becoming board certified in either clinical psychology or clinical child and adolescent psychology is discussed.
