- Background: A dysfunctional use of coping strategies has repeatedly been linked to suicidal behaviour in non-psychiatric populations. However, data regarding association between coping strategies and suicidal behaviour in psychiatric populations are limited. Aims: The aim of the study was to investigate the possible relationship between self-reported suicide risk, suicidal ideation and coping strategies in three psychiatric cohorts. Method: Three cohorts of psychiatric patients were involved in the study; recent suicide attempters (n = 55), suicide attempters at follow-up 12 years after a suicide attempt (n = 38) and patients with ongoing depression without attempted suicide (n = 72). Patients filled in the self-rating version of The Suicide Assessment Scale (SUAS-S) from which items no. 17–20 addressing current suicidal ideation were extracted. To investigate coping strategies, the Coping Orientation of Problem Experience Inventory (COPE) was used. Results: In all cohorts, regression analyses showed that only avoidant coping was significantly correlated with the scores of SUAS-S adjusted for covariates. The items no. 17–20 correlated significantly to avoidant coping but not with other coping strategies in all cohorts. Conclusion: The results of this study indicate that among coping strategies only avoidant coping may be associated with suicide risk in psychiatric patients independently of history of attempted suicide.

- Over recent years, requests for mtDNA analysis in the field of forensic medicine have notably increased, and the results of such analyses have proved to be very useful in forensic cases where nuclear DNA analysis cannot be performed. Traditionally, mtDNA has been analyzed by DNA sequencing of the two hypervariable regions, HVI and HVII, in the D-loop. DNA sequence analysis using the conventional Sanger sequencing is very robust but time consuming and labor intensive. By contrast, mtDNA analysis based on the pyrosequencing technology provides fast and accurate results from the human mtDNA present in many types of evidence materials in forensic casework. The assay has been developed to determine polymorphic sites in the mitochondrial D-loop as well as the coding region to further increase the discrimination power of mtDNA analysis. The pyrosequencing technology for analysis of mtDNA polymorphisms has been tested with regard to sensitivity, reproducibility, and success rate when applied to control samples and actual casework materials. The results show that the method is very accurate and sensitive; the results are easily interpreted and provide a high success rate on casework samples. The panel of pyrosequencing reactions for the mtDNA polymorphisms were chosen to result in an optimal discrimination power in relation to the number of bases determined.

- Unilateral hearing loss (UHL) occurs in 25% of cases of congenital sensorineural hearing loss. Due to the unilaterally reduced audibility associated with UHL, everyday demanding listening situations may be disrupted despite normal hearing in one ear. The aim of this study was to quantify acute changes in recognition of speech in spatially separate competing speech and sound localization accuracy, and relate those changes to two levels of temporary induced UHL (UHL 30 and UHL 43 ; suffixes denote the average hearing threshold across 0.5, 1, 2, and 4 kHz) for 8 normal-hearing adults. A within-subject repeated-measures design was used (normal binaural conditions, UHL 30 and UHL 43 ). The main outcome measures were the threshold for 40% correct speech recognition and the overall variance in sound localization accuracy quantified by an Error Index (0 = perfect performance, 1.0 = random performance). Distinct and statistically significant deterioration in speech recognition (2.0 dB increase in threshold, p < 0.01) and sound localization (Error Index increase of 0.16, p < 0.001) occurred in the UHL 30 condition. Speech recognition did not significantly deteriorate further in the UHL 43 condition (1.0 dB increase in speech recognition threshold, p > 0.05), while sound localization was additionally impaired (Error Index increase of 0.33, p < 0.01) with an associated large increase in individual variability. Qualitative analyses on a subject-by-subject basis showed that high-frequency audibility was important for speech recognition, while low-frequency audibility was important for horizontal sound localization accuracy. While the data might not be entirely applicable to individuals with long-standing UHL, the results suggest a need for intervention for mild-to-moderate UHL.

Tidskriftsartikel (refereegranskat)abstract
- Background: Depressed suicide attempters are, according to some earlier studies, treated more often with antipsychotics than depressive non-suicide attempters. Cluster B personality disorders, especially borderline personality disorder, are associated with a high suicide risk, and antipsychotics are commonly used for the reduction of symptoms. However, no previous study has taken comorbid personality disorders into account when assessing the use of antipsychotics in patients with unipolar depression. Therefore, the aim of this study was to investigate the clinical selection of pharmacotherapy in unipolar depression with and without a previous suicide attempt, taking into account potential confounders such as cluster B personality disorders. Methods: The study sample consisted of 247 patients with unipolar depression. The study was approved by the Regional Ethical Review Board in Lund, Sweden. Study participants were recruited from 4 different secondary psychiatric care clinics in Sweden and were diagnosed according to the DSM-IV-TR with the MINI and SCID II. Previous and ongoing psychiatric treatments were investigated in detail and medical records were assessed. Results: Thirty percent of the patients had made previous suicide attempts. Depressed suicide attempters underwent both lifetime treatment with antipsychotics and an ongoing antipsychotic treatment significantly more often than non-attempters. Significances remained after a regression analysis, adjusting for cluster B personality disorders, symptom severity, age at the onset of depression, and lifetime psychotic symptoms. Conclusions: This is the first study to consider the effect of comorbidity with cluster B personality disorders when comparing treatment of depressive suicide and non-suicide attempters. Our findings suggest that suicide attempters are more frequently treated with antipsychotics compared to non-suicide attempters, regardless of cluster B personality disorder comorbidity. These findings are important for clinicians to consider and would also be relevant to future studies evaluating reduction of suicide risk with antipsychotics in patients with psychiatric comorbidity and a history of attempted suicide.

- Objectives Depression is a common illness with substantial economic consequences for society and a great burden for affected individuals. About 30% of patients with depression do not respond to repeated treatments. Psychiatric comorbidity is known to affect duration, recurrence and treatment outcome of depression. However, there is a lack of knowledge on the extent to which psychiatric comorbidity is identified in the clinical setting for depressed patients in secondary psychiatric care. Therefore, the aim of this study was to compare the agreement between traditional diagnostic assessment (TDA) and a structured and comprehensive diagnostic procedure (SCDP) for identification of personality and anxiety disorder comorbidity in depressed patients in secondary psychiatric care. Methods 274 patients aged 18-77 were referred from four secondary psychiatric care clinics in Sweden during 2012-2017. ICD-10 diagnoses according to TDA (mostly unstructured by psychiatric specialist and residents in psychiatry), were retrieved from medical records and compared to diagnoses resulting from the SCDP in the study. This included the Mini International Neuropsychiatric Interview, the Structured Interview for DSM Axis II Personality Disorders and semi-structured questions on psychosocial circumstances, life-events, psychiatric symptoms, psychiatric treatments, substance use, and suicidal and self-harm behaviour. The assessment was carried out by psychiatric specialists or by residents in psychiatry with at least three years of psychiatric training. Results SCDP identified personality disorder comorbidity in 43% of the patients compared to 11% in TDA (p<0,0001). Anxiety disorder comorbidity was identified in 58% with SCDP compared to 12% with TDA (p<0,0001). Conclusions Important psychiatric comorbidity seems to be unrecognized in depressive patients when using TDA, which is routine in secondary psychiatric care. Comorbidities are better identified using the proposed model involving structured and semi-structured interviews together with clinical evaluations by clinical experts.

Tidskriftsartikel (refereegranskat)abstract
- Heart failure is a major health problem linked to poor quality of life and high mortality rates. Hence, novel biomarkers, such as fetal marker genes with low expression levels, could potentially differentiate disease states in order to improve therapy. In many studies on heart failure, cardiac biopsies have been analyzed as uniform pieces of tissue with bulk techniques, but this homogenization approach can mask medically relevant phenotypes occurring only in isolated parts of the tissue. This study examines such spatial variations within and between regions of cardiac biopsies. In contrast to standard RNA sequencing, this approach provides a spatially resolved transcriptome- and tissue-wide perspective of the adult human heart, and enables detection of fetal marker genes expressed by minor subpopulations of cells within the tissue. Analysis of patients with heart failure, with preserved ejection fraction, demonstrated spatially divergent expression of fetal genes in cardiac biopsies.

Vila och lärande om vila. En studie på livsvärldsfenomenologisk grund
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Avhandlingsarbetets syfte var att utifrån människors levda erfarenheter av vila, utveckla en tentativ teori om vila och om lärande avseende vila. Den kunskapen har utgjort grund för att beskriva hur förutsättningar för lärande avseende vila kan skapas. En modell för lärande avseede vila har utvecklats, i vilken en ömsesidighet mellan innehåll, lärande och förutsättningar för lärande beaktas. Studien genomfördes med en livsvärldsfenomenologisk ansats och med intervju som datainsamlingsmetod. Analysen genomfördes enligt en beskivande fenomenlogisk metodologi, i syfte att beskriva fenomenets generella struktur En generell struktur av fenomenet vila, implicerar en dualitet mellan vila och icke-vila. Essensen i vila utgörs av en harmoni i vilja, känsla och handling Vilan gestaltas i och med att en inre verklighet avseende behov och längtan överensstämmer med den yttre verklighetens beskaffenhet. Till vilans essens relateras innebördselementen: vilorytm i livet, stämningar av skönhet och trevnad, bejakad utan bedömning, frihet från bekymmer och tvång, samvaro med gemensamt intresse, att dröja, lustfylld stimulans och lustfylld utmaning. Essensen i icke- vila är disharmoni i vilja, känsla och handling. Upplevelsen av disharmoni tär på krafterna och blir allt påtagligare ju längre icke-vilan pågår. Att lära sig vila innebär att bli medveten om sitt behov av att ha en livsrytm som ger utrymme för vila, att tillåta sig att leva i en sådan rytm och att finna eller skapa källor där kraft kan hämtas. Modellen för lärande avseende vila består av tre dimensioner: lärande om vila, lärande i vila och lärande genom vila. Lärande om vila kan relateras till idëer om livsvärld, levd kropp, tid och rum, cirkularitet och intentionalitet. Lärande genom vila kan relateras till hälsa och lärande i vila kan relateras till etiska och estetiska aspekter.

- It has been suggested that the up-regulation of the tumour suppressor p16 gene and induction of senescence protect the phenotype of psoriatic involved skin from malignant transformation. On the other hand, Id1, which is inversely correlated with p16 has been shown to be up-regulated in psoriatic involved skin. To test the hypothesis that there may be an altered regulation of p16 in psoriatic involved skin, we have measured genes involved in the Igf-1 receptor signalling through the Ras/MAPK cascade. Igf-1R, IGFBP3, hRas, Ets2, JunB, Egr-1, Id1, MIDA1 and p16 gene expressions were measured using quantitative real-time PCR in total RNA isolated from punch biopsies from psoriatic involved (n = 9) and uninvolved skin (n = 9) and from cutaneous squamous cell cancer (SCC) involved (n = 8) and uninvolved skin (n = 8). The IGFBP3, hRas, JunB, Egr-1, Id1 and MIDA1 genes were up-regulated in psoriatic involved skin compared with uninvolved skin. The p16, JunB and MIDA1 genes were up-regulated in SCC involved skin compared with uninvolved skin. Our results indicate that there may be a balance between the proliferation and induction of senescence in psoriasis. This balance may vary and the psoriatic involved skin represented in this study appears to be in a proliferative state rather than senescence. Furthermore, we suggest that the noted up-regulation of JunB, which has been shown to up-regulate p16, in combination with the previously reported elevation of p16 expression in psoriatic involved skin, may indicate activation of a pathway by which JunB may protect the psoriatic plaque by inducing p16 in an event of malignant stress.
