- In this contribution examples of the application of new technologies to disentangle the mechanism of beta-delayed multiparticle emission are given. In particular the mechanism of beta-delayed two-proton emission from Ar-31 has been resolved and proved to be sequential, a preview of C-9-decay data is discussed. (C) 2002 Elsevier Science B.V.

- Aim To describe, analyse and interpret symbolic leadership in Swedish public hospitals. Background Swedish hospitals are undergoing major structural changes. Hospitals are amalgamated in order to increase productivity and accessibility and reduce health care costs. Method In-depth interviews have been performed with 54 politicians, senior civil servants, medical directors and trade union representatives at nine hospitals. The interviews have been analysed and interpreted following a grounded theory approach. Findings The results show that leadership is manifested in two dimensions—management and symbolic leadership. The management dimension comprises general leadership aspects like planning, regulation and control. In the symbolic leadership dimension, the leader acts as a guide, inspirer and visionary. Leaders consider they are acting in two large arenas: a public arena and a hospital arena. In the public arena their professional competence is thought to be most important and in the hospital arena their social competence. Conclusions Structural changes in Swedish hospitals have forced the actors to come out into the public arena, where they increasingly meet the media and have to defend budget cut-backs. This reduces their manoeuvring space in the hospital arena. When leaders work as a team, and make full use of their symbolic role, this helps to promote the process of transition. Symbolic leadership has a potential to increase the role repertory for not least the head nurse.

- Objectives This study assessed paternal occupational exposure to di(2-ethylhexyl)phthalate (DEHP) in association with reduced fertility. Methods Men working in three plants with DEHP exposure were studied retrospectively. Male and female employees and their partners were invited to participate if they had reported a pregnancy or an attempt to achieve a pregnancy. Postal questionnaires and telephone interviews were used to collect additional data from the men and women, respectively. Information on time to pregnancy was eligible for 326 pregnancies fathered by 193 men. Male exposure to DEHP during every month of their time to pregnancy was classified into one of three exposure categories. The exposure ranged from <0.1 to 2.1 mg/ml(3). The fathers of only four pregnancies had DEHP exposure of >0.5 mg/m(3) during the time to pregnancy. The pregnancies of employed women with unexposed partners or pregnancies of employed men unexposed during the time to pregnancy formed the reference group. Results The fecundability ratio for time to pregnancy was 1.07 [95% confidence interval (95% Cl) 0.84-1.351 for those with low exposure and 0.97 (95% CI 0.70-1.33) for the highly exposed after adjustment for the father's age, mother's age, and length of recall. When the analyses were restricted to first pregnancy, the fecundability ratio was 1.13 (95% Cl 0.83-1.56) for low exposure and 1.02 (95% Cl 0.66-1.59) for high exposure. Conclusions Time to pregnancy is not prolonged among couples with paternal exposure to DEHP at a mean exposure level of <0.5 mg/ml.

- AIM: To evaluate factors which, prior to hospital admission, predict the development of acute coronary syndrome or acute myocardial infarction among patients who call for an ambulance due to suspected acute coronary syndrome. DESIGN: Prospective observational study. METHODS: All the patients who called for an ambulance due to suspected acute coronary syndrome in South Hospital's catchment area in Stockholm and in the Municipality of Göteborg between January and November 2000, were included. On arrival of the ambulance crew, a blood sample was drawn for bedside analysis of serum myoglobin, creatine kinase (CK)MB and troponin-I. A 12-lead electrocardiogram (ECG) was simultaneously recorded. RESULTS: In all, 538 patients took part in the survey. Their mean age was 69 years and 58% were men. In all, 307 patients (57.3%) had acute coronary syndrome and 158 (29.5%) had acute myocardial infarction. Independent predictors of the development of acute coronary syndrome were a history of myocardial infarction (P=0.006), angina pectoris (P=0.005) or hypertension (P=0.017), ECG changes with ST elevation (P<0.0001), ST depression (P<0.0001) or T-wave inversion (P=0.012) and the elevation of CKMB (P=0.005). Predictors of acute myocardial infarction were being a man (P=0.011), ECG changes with ST elevation (P<0.0001) or ST depression (P<0.0001), the elevation of CKMB (P<0.0001) and a short interval between the onset of symptoms and blood sampling (P=0.010). CONCLUSION: Among patients transported by ambulance due to suspected acute coronary syndrome, predictors of myocardial damage can be defined prior to hospital admission on the basis of previous history, sex, ECG changes, the elevation of biochemical markers and the interval from the onset of symptoms until the ambulance reaches the patient.

Halo excitations in fragmentation of He-6 at 240 MeV/u on carbon and lead targets

- Dissociation of a 240 MeV/u beam of He-6, incident on carbon and lead targets, has been studied in kinematically complete experiments to investigate low-lying excitation modes in the halo nucleus He-6. It is shown that alignment effects characterize the inelastic scattering and allow an unambiguous assignment of the spin of a narrow resonance observed in the excitation energy spectrum. The differential cross sections for the He-6 inelastic scattering on carbon and lead targets were deduced from the measured moments of the two neutrons and the a-particle. An analysis of these distributions shows that quadrupole and, possibly, monopole excitations characterize the hadronic interaction, while the dipole mode is dominating in Coulomb dissociation. Neither theoretically predicted new resonance states in He-6 nor nuclear excitation of a dipole mode were found. Direct evidence has been obtained for strong suppression of Coulornb post-acceleration in direct Coulomb breakup in a lead target.

- Pain is common among elderly. Very sick elderly persons living in nursing homes often have communication problems because of dementia or stroke, which causes problem to judge pain and evaluate effects of pain treatment. The aim of this study was to describe the prevalence, localisation and expressions of pain and to evaluate the usefulness of some pain assessment methods for nursing home residents. The study included 66 elderly living in a nursing home of which 49% had dementia as main medical diagnosis. A specially trained registered nurse (RN) performed pain assessment by * presenting a set of pain assessment tools * interpreting the nursing home residents' reactions during activity and * interviewing the resident about perceived pain. Two physiotherapists (PTs) performed physical examination including assessment of joint motion and palpation of joints and muscles. Contractures and ambulating status were noted. Cognitive Performance Scale (CPS) assessed cognitive capacity. When assisted by the RN 61% of the residents used independent or by assistance a verbal rating scale. The RN made an estimation of pain in all the nursing home residents and the PTs examined 92% of the residents. Pain was identified in 88% of the residents, 42% of the residents were treated with analgesics and pain it-as documented in the nurses' daily notes in 27% of the patient records. All residents with contractures had pain in the engaged joint. This study indicates that it is possible to assess pain by combining interview and interpretation of the residents' reactions during activity. Detection of pain by physical examination is a valuable complement especially for persons with decreased ability to communicate.
