- The structural effect on the metal-to-ligand charge transfer (MLCT) excited-state lifetime has been investigated in bis-tridentate Ru(II)-polypyridyl complexes based on the terpyridine-like ligands [6-(2,2'-bipyridyl)](2-pyridyl)methane (1) and 2-[6-(2,2'-bipyridyl)]-2-(2-pyridyl)propane (2). A homoleptic ([Ru(2)(2)](2+)) and a heteroleptic complex ([Ru(ttpy)(2)](2+)) based on the new ligand 2 have been prepared and their photophysical and structural properties studied experimentally and theoretically and compared to the results for the previously reported [Ru(1)(2)](2+). The excited-state lifetime of the homoleptic Ru-II complex with the isopropylene-bridged ligand 2 was found to be 50 times shorter than that of the corresponding homoleptic Ru-II complex of ligand 1, containing a methylene bridge. A comparison of the ground-state geometries of the two homoleptic complexes shows that steric interactions involving the isopropylene bridges make the coordination to the central Ru-II ion less octahedral in [Ru(2)(2)](2+) than in [Ru(1)(2))(2+). Calculations indicate that the structural differences in these complexes influence their ligand field splittings as well as the relative stabilities of the triplet metal-to-ligand charge transfer ((MLCT)-M-3) and metal-centered ((MC)-M-3) excited states. The large difference in measured excited-state lifetimes for the two homoleptic Ru-II complexes is attributed to a strong influence of steric interactions on the ligand field strength, which in turn affects the activation barriers for thermal conversion from (MLCT)-M-3 states to short-lived (MC)-M-3 states.

Journal article (peer-reviewed)abstract
- CONTEXT: The effect of GH therapy in short non-GH-deficient children, especially those with idiopathic short stature (ISS), has not been clearly established owing to the lack of controlled trials continuing until final height (FH).OBJECTIVE: The aim of the study was to investigate the effect on growth to FH of two GH doses given to short children, mainly with ISS, compared with untreated controls.DESIGN AND SETTING: A randomized, controlled, long-term multicenter trial was conducted in Sweden.INTERVENTION: Two doses of GH (Genotropin) were administered, 33 or 67 microg/kg.d; control subjects were untreated.SUBJECTS: A total of 177 subjects with short stature were enrolled. Of these, 151 were included in the intent to treat (AllITT) population, and 108 in the per protocol (AllPP) population. Analysis of ISS subjects included 126 children in the ITT (ISSITT) population and 68 subjects in the PP (ISSPP) population.MAIN OUTCOME MEASURES: We measured FH sd score (SDS), difference in SDS to midparenteral height (diff MPHSDS), and gain in heightSDS.RESULTS: After 5.9+/-1.1 yr on GH therapy, the FHSDS in the AllPP population treated with GH vs. controls was -1.5+/-0.81 (33 microg/kg.d, -1.7+/-0.70; and 67 microg/kg.d, -1.4+/-0.86; P<0.032), vs. -2.4+/-0.85 (P<0.001); the diff MPHSDS was -0.2+/-1.0 vs. -1.0+/-0.74 (P<0.001); and the gain in heightSDS was 1.3+/-0.78 vs. 0.2+/-0.69 (P<0.001). GH therapy was safe and had no impact on time to onset of puberty. A dose-response relationship identified after 1 yr remained to FH for all growth outcome variables in all four populations.CONCLUSION: GH treatment significantly increased FH in ISS children in a dose-dependent manner, with a mean gain of 1.3 SDS (8 cm) and a broad range of response from no gain to 3 SDS compared to a mean gain of 0.2 SDS in the untreated controls.

- What do we know about the prevalence and the specific features of autism spectrum disorders (ASDs) among subjects in forensic psychiatry and special youth centres? A clinical case series consisting of 42 subjects with ASD, recruited from three well-characterized populations in forensic psychiatry and special youth care, was used to determine: 1) the prevalence of ASD in these institutions (at least 13%), 2) the distribution of diagnostic criteria in this special population (mostly social interaction and communication problems, few or atypical flexibility problems), 3) the degree of comorbidity (the rule rather than the exception), 4) neuropsychological test profiles (lowered IQ with uneven profiles), 5) types of crimes and offences (very heterogeneous, often stress-related with dissociated features), 6) mental health care needs (high), and 7) special clinical features (especially expressions of flexibility deficits in non-classical areas and proneness to dissociation). This descriptive study indicates that ASD is a clinically relevant problem among forensic populations that has to be considered in diagnostics, assessments of needs and treatment planning.

Journal article (peer-reviewed)abstract
- The Autism – Tics, AD/HD, and other Comorbidities inventory (A-TAC) is a comprehensive interview for evaluating problems related to autism spectrum disorders (ASD), tic disorders, attention-deficit/hyperactivity disorder (AD/HD), and common comorbid conditions in children and adolescents. A-TAC telephone interviews were administered to parents of 2,957 children aged nine- or twelve-years, representing one in each twin pair included in the population- based Child and Adolescent Twin Study in Sweden (CATSS). A total of 16.4% were screen-positive for one or several of the targeted disorder, 1.3% for ASD and 5.6% for AD/HD. All types of problems were more common among boys, with the exception of those related to “eating habits”. They were all dimensionally/continuously distributed, highly inter-correlated, and overlapped across types. They aggregated in three ba- sic factors corresponding to externalizing/disruptiveness, socio-communicative problems, and compulsiveness. Population-based data on problems in children thus challenge current categorical diagnostic definitions, calling for dimen- sional and complementary models of problem descriptions.

- There is a paucity of studies assessing changes in measures of human neurotransmission during stressful events, such as surgery. Thirty-five patients without any neurological disorders undergoing knee replacements with spinal bupivacaine anaesthesia and propofol sedation had cerebrospinal fluid (CSF) drawn from a spinal catheter before, three hours after and the morning after surgery. The CSF concentrations of the dopamine metabolite homovanillinic acid (HVA) and the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA), which are related to the activity of the dopaminergic and serotonergic systems of the brain, increased sharply during surgery and reached 188% and 166% of their initial concentrations on the morning after the intervention (p < 0.0001). The CSF concentrations of the norepinephrine metabolite 3-methoxy-4-hydroxyphenylglucol (MHPG) increased modestly (non-significantly) during and after surgery. The HVA/5-HIAA ratios initially increased but returned to the initial level during the night after surgery. We conclude that non-neurological surgery, in this case to the lower limb, is accompanied by a marked central nervous stress response in spite of a spinal blockade.

- BACKGROUND: Radiographers' ability and competence is a matter of vital importance for patients. Nursing care is an integral part of the radiographer's work. The demand for high competence in clinical activities has increased in diagnostic radiology and has had an impact on the development of the profession.AIM: The aim was to describe the radiographer's areas of professional competence in relation to good nursing care based on critical incidents that occur in the course of radiological examinations and interventions.METHOD: A descriptive design with a qualitative approach, using the Critical Incident Technique was employed. Interviews were conducted with a strategic sample of registered radiographers (n = 14), based at different hospitals in Sweden.ETHICAL ISSUES: The appropriate ethical principles were followed. All the participants provided informed consent, and formal approval for conducting the research was obtained according to national and local directives.RESULTS: The data analysis resulted in two main areas; direct and indirect patient-related areas of competence, which describe the radiographers' skills that either facilitate or hinder good nursing care. In the direct patient-related area of competence, four categories emerged, which illustrate good nursing care in the patient's immediate surroundings. In the indirect patient-related area of competence, four categories illuminated good nursing care that is provided without direct contact with the patient.CONCLUSIONS: The study highlights the different areas of the radiographer's unique professional competence. The findings provide insight into the radiographer's profession, on one hand as a carer and on the other as a medical technologist as well as highlighting the importance of each role. The radiographer's work encompasses a variety of components--from caring for the patient to handling and checking the technical equipment.
