Effects of a psychiatric intensive care unit in an acute psychiatric department

Psychiatric acute units use different levels of segregation to satisfy needs for containment and decrease in sensory input for behaviourally disturbed patients. Controlled studies evaluating the effects of the procedure are lacking. The aim of the present study was to compare effects in acutely admitted patients with the use of a psychiatric intensive care unit (PICU) and not in a psychiatric acute department. In a naturalistic study, one group of consecutively referred patients had access only to the PICU, the other group to the whole acute unit. Data were obtained for 56 and 62 patients using several scales. There were significant differences in reduction of behaviour associated with imminent, threatening incidents (Broset Violence Checklist), and actual number of such incidents (Staff Observation Aggression Scale-Revised) in favour of the group that was treated in a PICU. The principles of patient segregation in PICUs have favourable effects on behaviours associated with and the actual numbers of violent and threatening incidents.

Patient experiences of uncertainty – a synthesis to guide nursing practice and research Aim The aim of this study was to provide a synthesis of patients’ experiences of uncertainty in illness and the interventions outlined, based on qualitative research. Background There is a need to explore various patient experiences from a nursing perspective in order to achieve evidence-based practice and improve the quality of care. Uncertainty in illness is a dynamic experience – a stressor with a major impact on patients’ illnesses. Methods A literature search performed on PubMed and Cinahl yielded 15 qualitative studies that met the inclusion criteria and which were analysed and interpreted. Results Experienced uncertainty was one of two main areas comprising three themes: explaining, feeling and facing uncertainty. The second main area was suggested intervention strategies consisting of three themes: organizing the patient trajectory throughout the health-care system, supporting patients through relationships and providing knowledge through clear and accurate communication. Conclusion Providing insight, confidence and supporting the patients’ feeling of control are of importance for health-care professionals. Implications for nursing management Structured organization of the trajectory system should be followed up, while outcome measures (patient satisfaction), education and training programmes for patients and families after discharge to improve coping strategies and reduce uncertainty should be developed. Nurse leaders should work towards the establishment of clinical academic nursing positions to integrate knowledge, skills, experiences and research into everyday routines.

Impact of sunlight on the age of onset of bipolar disorder. Bipolar Disord 2012: 14: 654–663. © 2012 The Authors. Journal compilation © 2012 John Wiley & Sons A/S. Objective: Although bipolar disorder has high heritability, the onset occurs during several decades of life, suggesting that social and environmental factors may have considerable influence on disease onset. This study examined the association between the age of onset and sunlight at the location of onset. Method: Data were obtained from 2414 patients with a diagnosis of bipolar I disorder, according to DSM‐IV criteria. Data were collected at 24 sites in 13 countries spanning latitudes 6.3 to 63.4 degrees from the equator, including data from both hemispheres. The age of onset and location of onset were obtained retrospectively, from patient records and/or direct interviews. Solar insolation data, or the amount of electromagnetic energy striking the surface of the earth, were obtained from the NASA Surface Meteorology and Solar Energy (SSE) database for each location of onset. Results: The larger the maximum monthly increase in solar insolation at the location of onset, the younger the age of onset (coefficient= ?4.724, 95% CI: ?8.124 to ?1.323, p = 0.006), controlling for each country’s median age. The maximum monthly increase in solar insolation occurred in springtime. No relationships were found between the age of onset and latitude, yearly total solar insolation, and the maximum monthly decrease in solar insolation. The largest maximum monthly increases in solar insolation occurred in diverse environments, including Norway, arid areas in California, and Chile. Conclusion: The large maximum monthly increase in sunlight in springtime may have an important influence on the onset of bipolar disorder.     

A systematic review of risks and benefits with nipple-areola-reconstruction

Background: Most women who have their breast reconstructed are offered NAC reconstruction. Nonetheless, it is unclear what scientific evidence there is for the procedure. The aims of the present systematic review were to evaluate the quality of evidence for benefits and risks with NAC reconstruction, and to examine the evidence for different techniques.

Methods: Relevant databases were searched. Inclusion criteria were controlled studies comprising ≥20 patients and a case series of ≥50 patients. Included articles had to meet criteria defined in a PICO (Patient, Intervention, Comparison, and Outcome). Data extraction and collection were performed according to the QUADAS tool. The level of evidence of the selected articles was assessed according to the Oxford Centre for Evidence-Based Medicine 2009 guidelines, and total evidence for the different research questions was graded according to the GRADE-system.

Results: A total of 362 abstracts were retrieved following the search. Of these 325 did not meet the inclusion criteria and were excluded, leaving 37 studies to be included in the review. Among these, 36 were case series and one a small randomised non-blinded study

Conclusions: The existing quality of evidence for risks and benefits of the operation is very low. It is unclear what the complication frequencies are after the reconstruction, and what effect on quality-of-life the operation has. Prospective studies of high quality are needed to evaluate the health effects and risks with NAC reconstruction.     

Mode of delivery of Cognitive Behavioral Therapy for Insomnia: a randomized controlled non-inferiority trial of digital and face-to-face therapy

Study ObjectivesDigital Cognitive Behavioral Therapy for Insomnia (dCBT-I) has demonstrated efficacy in reducing insomnia severity in self-referred and community samples. It is unknown, however, how dCBT-I compares to individual face-to-face (FtF) CBT-I for individuals referred to clinical secondary services. We undertook a randomized controlled trial to test whether fully automated dCBT-I is non-inferior to individual FtF CBT-I in reducing insomnia severity.MethodsEligible participants were adult patients with a diagnosis of insomnia disorder recruited from a sleep clinic provided via public mental health services in Norway. The Insomnia Severity Index (ISI) was the primary outcome measure. The non-inferiority margin was defined a priori as 2.0 points on the ISI at week 33.ResultsIndividuals were randomized to FtF CBT-I (n = 52) or dCBT-I (n = 49); mean baseline ISI scores were 18.4 (SD 3.7) and 19.4 (SD 4.1), respectively. At week 33, the mean scores were 8.9 (SD 6.0) and 12.3 (SD 6.9), respectively. There was a significant time effect for both interventions (p < 0.001); and the mean difference in ISI at week 33 was −2.8 (95% CI: −4.8 to −0.8; p = 0.007, Cohen’s d = 0.7), and −4.6 at week 9 (95% CI −6.6 to −2.7; p < 0.001), Cohen’s d = 1.2.ConclusionsAt the primary endpoint at week 33, the 95% CI of the estimated treatment difference included the non-inferiority margin and was wholly to the left of zero. Thus, this result is inconclusive regarding the possible inferiority or non-inferiority of dCBT-I over FtF CBT-I, but dCBT-I performed significantly worse than FtF CBT-I. At week 9, dCBT-I was inferior to FtF CBT-I as the 95% CI was fully outside the non-inferiority margin. These findings highlight the need for more clinical research to clarify the optimal application, dissemination, and implementation of dCBT-I.

Association analysis of ANK3 gene variants in nordic bipolar disorder and schizophrenia case-control samples

Genetic variants in ankyrin 3 (ANK3) have recently been shown to be associated with bipolar disorder (BD). We genotyped three ANK3 SNPs previously found to be associated with BD (rs10994336, rs1938526, and rs9804190) in a Scandinavian BD case-control sample (N = 854/2,614). Due to evidence of genetic overlap between BD and schizophrenia (SZ), we also genotyped these three SNPs in a Scandinavian SZ case-control sample (N = 1,073/2,919). Combining our Scandinavian samples with an Icelandic sample (N = 435 BD cases, 651 SZ cases, and 11,491 healthy controls), we found rs10994336 and rs9804190 to be nominally significantly associated with BD in this combined Nordic BD sample (N = 1,289/14,105). Nominal P was 0.015/0.018 (fixed/random effect) for rs10994336 (Bonferroni corrected P = 0.044/0.053) and 0.023 for rs9804190 (Bonferroni corrected P = 0.069). None of the SNPs were significantly associated with SZ in the combined Nordic SZ case-control sample (N = 1,724/14,410). These results further support that ANK3 is a susceptibility gene specific to BD and that more than one risk locus is involved.     

Photodynamic therapy using topical methyl aminolevulinate vs surgery for nodular basal cell carcinoma: results of a multicenter randomized prospective trial

BACKGROUND: Photodynamic therapy (PDT) is increasingly used as a noninvasive treatment for nodular basal cell carcinoma (BCC), without a sound evidence base. OBJECTIVE: To compare topical PDT, with the use of the sensitizer methyl aminolevulinate, and standard excision surgery in nodular BCC. DESIGN: Prospective, randomized study. SETTING: University dermatology departments. PATIENTS: A total of 101 adults with previously untreated nodular BCC. INTERVENTIONS: Patients received methyl aminolevulinate PDT (n = 52) or surgery (n = 49). The PDT was given twice, 7 days apart, with methyl aminolevulinate cream (160 mg/g) and 75 J/cm(2) red light (570-670 nm). Thirteen patients with a noncomplete response to PDT at 3 months (24% lesions) were retreated. OUTCOME MEASURES: Primary end point was clinically assessed lesion clearance at 3 months after treatment. Secondary end points were sustained response rate at 12 months and cosmetic outcome at 3 and 12 months. Cosmesis and lesion recurrence were further assessed at 24 months. RESULTS: Data from 97 patients (105 lesions) were included in the 3-month per-protocol analysis. Complete response rates did not differ significantly between groups (51/52 [98%] lesions with surgery vs 48/53 [91%] lesions with methyl aminolevulinate PDT; difference [95% confidence interval], 4.8% (-3.4% to 13.0%]; P =.25). At 12 months, tumor-free rates were 50 (96%) of 52 lesions with surgery vs 44 (83%) of 53 with methyl aminolevulinate PDT (P =.15). More patients treated with methyl aminolevulinate PDT than surgery had an excellent or good cosmetic outcome at all time points (significant at 12 and 24 months on patient assessment, P<.05, and at 3, 12, and 24 months on investigator evaluation, P<.001). At 24 months, 5 lesions that had initially cleared with methyl aminolevulinate PDT had recurred, compared with 1 after surgery. CONCLUSIONS: Methyl aminolevulinate PDT is an effective treatment for nodular BCC, and while there is a trend for higher recurrence with this modality, it conveys the advantage over surgery of better cosmesis.
