Abstract [en]

Background: Many similarities exist between borderline personality disorder (BPD) and attention-deficit/hyperactivity disorder (ADHD), more so in women than in men. People with comorbid ADHD and BPD represent a subgroup of BPD patients with distinct symptom expression and, consequently, a different prognosis. We used Swedish national high quality registers to assess whether such comorbidity is related to increased mortality risk. The study focused on women with BPD because they are more likely than men to be clinically diagnosed with BPD and present a higher mortality risk, especially for unnatural causes of death, including suicide. Findings: In a cohort of 15 847 women diagnosed with BPD a subsequent clinical diagnosis of ADHD did not influence the overall risk of mortality, including suicide. Conclusions: Women with comorbid ADHD and BPD have a similar mortality risk as those only diagnosed with BPD.

Abstract [en]

Background

People with a personality disorder have a higher mortality and reduced life expectancy than the general population. Childbearing is thought to have a protective effect on morbidity and mortality. Yet, there are no studies on whether childbearing is related to a lower mortality among women with personality disorder.

Aims

This study examined associations between childbearing and mortality among women with personality disorder. Our hypothesis was that parity would be associated with lower mortality.

Method

This register-based cohort study included 27 412 women treated for personality disorder in in-patient or specialised out-patient care between 1990 and 2015. We used nationwide population-based registers to obtain information on sociodemographics, child delivery, healthcare use and mortality. Mortality risk estimates were calculated as hazard ratios (HRs) with 95% CIs using Cox regression. Adjustments were made for year of birth, educational level, age at diagnosis, comorbidity and severity of personality disorder.

Results

Nulliparous women had a nearly twofold increased mortality risk (adjusted HR = 1.78, 95% CI 1.50–2.12) compared with parous women and over twofold mortality risk (adjusted HR = 2.29, 95% CI 1.72–3.04) compared with those giving birth after their first personality disorder diagnosis. Those giving birth before their first personality disorder diagnosis had a 1.5-fold higher risk of mortality than those giving birth after their first personality disorder diagnosis (adjusted HR = 1.48, 95% CI 1.06–2.07). There was a threefold risk of suicide in nulliparous women compared with those giving birth after their first personality disorder diagnosis (adjusted HR = 2.90, 95% CI 1.97–4.26).

Conclusions

Childbearing history should be an integral part of the clinical evaluation of women with personality disorder.

Abstract [en]

Objective: A history of psychiatric disorders is more common among patients who have had burns than in the general population. To try and find out the scale of the problem we have assessed self-reported symptoms of anxiety and depression after a burn. Methods: Consecutive patients with burns measuring more than 10% total body surface area or duration of stay in hospital of seven days or more were included. Personal and clinical details about the patients were extracted from the database at each center. Data were collected from the Hospital Anxiety and Depression Scale, as well as Health-Related Quality of Life (HRQoL; Short Form-36, SF-36) and questionnaires about socioeconomic factors. All results were obtained 12 and 24 months after the burn, and compared with those from a reference group. Results: A total of 156 patients responded to the questionnaires. Mean (SD) age and TBSA (%) were 46 (16.4) years and 23.6 (19.2) %, respectively. There were no differences in incidence between the burn and reference groups in anxiety or depression either 12 or 24 months after the burn. Those who reported higher anxiety and depression scores also had consistently poorer HRQoL as assessed by the SF-36. Conclusion: Seen as a group, people who have had burns report anxiety and depression the same range as a reference group. Some patients, however, express more anxiety and depression, and concomitantly poorer HRQoL. These patients should be identified, and offered additional support. (C) 2019 Elsevier Ltd and ISBI.

Abstract [en]

Cell migration requires spatiotemporal integration of signals that regulate cytoskeletal dynamics. In response to a migration-promoting agent, cells begin to polarise and extend protrusions in the direction of migration. These cytoskeletal rearrangements are orchestrated by a variety of proteins, including focal adhesion kinase (FAK) and the Rho family of GTPases. CCN2, also known as connective tissue growth factor, has emerged as a regulator of cell migration but the mechanism by which CCN2 regulates keratinocyte function is not well understood. In this article, we sought to elucidate the basicmechanism of CCN2-induced cellmigration in human keratinocytes. Immunohistochemical staining was used to demonstrate that treatment with CCN2 induces a migratory phenotype through actin disassembly, spreading of lamellipodia and re-orientation of the Golgi. In vitro assays were used to show that CCN2-induced cell migration is dependent on FAK, RhoA and Cdc42, but independent of Rac1. CCN2-treated keratinocytes displayed increased Cdc42 activity and decreased RhoA activity up to 12 hours post-treatment, with upregulation of p190RhoGAP. An improved understanding of how CCN2 regulates cell migration may establish the foundation for future therapeutics in fibrotic and neoplastic diseases.

Abstract [en]

Background: Chronic pain after burn can have severe physical and psychological effects on former patients years after the initial injury. Although the issue of pain after burn has gained increased attention over the past years, prospective, longitudinal studies are scarce. Our aim was to prospectively investigate consecutive burn patients for pain severity over time and to evaluate the prevalence and characteristics of post-burn pain to 2-7 years after the burn. As an additional aim, the effects of burn and individual-related factors, especially health related Quality of Life (HRQoL), were investigated.

Method: Sixty-seven consecutive burn patients were assessed during acute care at 3, 6, 12 and 24 months, as well as at 2-7 years post-burn. HRQoL, symptoms of post-traumatic stress disorder (PTSD) and other psychiatric disorders were investigated. During the interviews that took place 2-7 years after the injury (mean 4.6 1.9 years), current chronic post-burn pain was assessed using the Brief Pain Inventory-Short Form (BPI-SF).

Results: One-third of the patients still reported pain 2-7 years after the injury. Pain severity and interference with daily life were mainly mild to moderate though they were found to be associated with significantly lower HRQoL. Chronic pain after bum was associated with both burn- and individual-related factors. In logistic regression analysis HRQoL at 3 and 12 months and symptoms of PTSD at 12 months were independent factors in predicting chronic pain after burn.

Conclusion: Pain after burn becomes a chronic burden for many former burn patients and decreases HRQoL. A novel finding in this study was that HRQoL assessed early after burn was a predictor for the development of chronic pain. This finding may help to predict future pain problems and serve as an indicator for pain preventive measures.

Abstract [en]

Background: Tumor stroma is similar to the connective tissue of chronic inflammation. The extracellular matrix of tumors is formed by cancer-associated fibroblasts that also modulate the inflammatory response. Materials and Methods: We studied the ability of oral keratinocytes (NOK) and oral squamous cell carcinoma cells (SCC) to induce an innate immune response in fibroblasts. Co-cultures with fibroblasts in collagen gels and keratinocytes in inserts were used. Pentraxin 3 (PTX3) was used as an indicator of an innate immune response. Results: SCC and NOK up-regulated fibroblast mRNA expression and protein release of PTX3. mRNA levels were more pronounced in cultures with malignant cells. The induction of PTX3 was abrogated by an interleukin-1 receptor antagonist Conclusion: Keratinocytes have the capacity to induce an interleukin-1-dependent innate immune response by fibroblasts in vitro. This could be important for subsequent fibroblast modulation of the inflammatory reaction in non-malignant and malignant disease processes.

Abstract [en]

Objective: The influence of psychopathology on suicide method has revealed different distributions among different psychiatric disorders. However, evidence is still scarce. We hypothesized that having a diagnosis of personality disorder (PD) affect the suicide method, and that different PD clusters would influence the suicide method in different ways. In addition, we hypothesized that the presence of psychiatric and somatic co-morbidity also affects the suicide method. Method: We examined 25,217 individuals aged 15-64 who had been hospitalized in Sweden with a main diagnosis of PD the years 1987-2013 (N = 25,217). The patients were followed from the date of first discharge until death or until the end of the follow-up period, i.e. December 31, 2013, for a total of 323,508.8 person-years, with a mean follow up time of 11.7 years. The SMR, i.e. the ratio between the observed number of suicides and the expected number of suicides, was used as a measure of risk. Results: Overall PD, different PD-clusters, and comorbidity influenced the suicide method. Hanging evidenced highest SMR in female PD patients (SMR 34.2 (95% CI: 29.3-39.8)), as compared to non-PD patients and jumping among male PD patients (SMR 24.8 (95% CI: 18.3-33.6)), as compared to non PD-patients. Furthermore, the elevated suicide risk was related to both psychiatric and somatic comorbidity. Conclusion: The increased suicide risk was unevenly distributed with respect to suicide method and type of PD. However, these differences were only moderate and greatly overshadowed by the overall excess suicide risk in having PD. Any attempt from society to decrease the suicide rate in persons with PD must take these characteristics into account.

Abstract [en]

BackgroundAlthough personality disorders are associated with increased overall mortality, less is known about cause of death and personality type.AimsTo determine causes of mortality in ICD personality disorders.MethodBased on data from Swedish nationwide registers, individuals admitted to hospital with a primary diagnosis of personality disorder between 1987 and 2011 were followed with respect to mortality until 31 December 2011. Standardised mortality ratios (SMRs) with 95% confidence intervals and underlying causes of death were calculated.ResultsAll-cause SMRs were increased, overall and in all clusters, for natural as well as unnatural causes of death. The overall SMR was 6.1 in women and 5.0 in men, as high as previously reported for anorexia nervosa, with higher rates in cluster B and mixed/other personality disorders. The SMR for suicide was 34.5 in women and 16.0 in men for cluster B disorders. Somatic and psychiatric comorbidity increased SMRs.ConclusionsThe SMR was substantially increased for all personality disorder clusters. Thus, there was an increased premature mortality risk for all personality disorders, irrespective of category.

Abstract [en]

Personality disorders (PDs) are associated with increased overall mortality. In patients hospitalised with a principal diagnosis of PD, this is observed for all clusters and for natural as well as unnatural causes of death. Data from Swedish nationwide registers were used to assess whether this was also true for the majority of patients diagnosed with PDs not severe enough to lead to hospitalisation. There was an increased mortality in all clusters, and for natural as well as unnatural death, also in patients treated as out-patients only, although not to the same extent as in those hospitalised.

Abstract [en]

Purpose: Personality disorders (PDs) are associated with significant distress, disability, and cause great difficulties in life. PDs have been suggested to influence adaptation after major burns, but the potential relationship has not been fully elucidated. This study aimed to describe the prevalence of PDs in 107 patients with major burn injury, and to identify the impact of PDs on perceived patient outcome assessed as health-related quality of life (HRQoL) one year after burn. Methods: One burn-specific instrument (Burn Specific Health Scale-Brief (BSHS-B)) and two generic instruments (EuroQol Five Dimensions and Short Form 36 Health Survey) were used, and Psychiatric Axis I and II disorders were assessed one year post burn. Results: This study identified an above normal prevalence of PDs among individuals afflicted by burn, and participants with PD had a significantly larger lifetime burden of Axis I disorders compared to participants without PD. Participants with PDs scored significantly lower than those without PD in the BSHS-B domain Skin involvement, and the effect of having a PD was related to the subscale Treatment regimens. There was no relationship between the presence of PD and generic HRQoL. Conclusions: An implication of these observations is that special rehabilitation efforts including more tailored interventions must be offered to these patients to ensure that the obstacles they perceive to caring for themselves in this respect are eliminated.
