The association of cannabis use with quality of life and psychosocial functioning in psychosis

BACKGROUND: Cannabis use is highly prevalent among people with a psychotic disorder. They often report sociality, coping with unpleasant affect and having positive experiences as important reasons for cannabis use, suggesting that cannabis improves their quality of life (QoL) and psychosocial functioning. However, based on previous studies we hypothesize that cannabis use is negatively associated with long-term subjective QoL and psychosocial functioning in people with a psychotic disorder. METHODS: We included 2994 people with a psychotic disorder (36.4% female), mean age 44.4 (SD 11.9), mean illness duration 17.2 years (SD 11.1), who participated in two yearly routine outcome assessments between 2014 and 2018 (interval 9-15 months) from the naturalistic PHAMOUS cohort study. Linear regression analyses were used to examine whether first assessment cannabis use was associated with QoL (ManSA) and psychosocial functioning (HoNOS). Changes in outcomes between assessments were analyzed with AN(C)OVA, to examine differences between continuers (n = 255), discontinuers (n = 85), starters (n = 83) and non-users (n = 2571). RESULTS: At first assessment, 11.4% was using cannabis. They had lower QoL (B = -2.93, p < 0.001) and worse psychosocial functioning (B = 1.03, p = 0.002) than non-users. After one year, changes in QoL and psychosocial functioning were not significantly different between continuers, starters, discontinuers and non-users. CONCLUSIONS: Cannabis users were less satisfied with their family relations and financial situation and showed more aggressive and disruptive behavior and self-harm than non-users. These differences are likely the result of patients having used cannabis for many years. Starting or discontinuing cannabis did not lead to changes in QoL and psychosocial functioning within one year

Cerebral palsy with dislocated hip and scoliosis: what to deal with first?

PURPOSE:Hip dislocation and scoliosis are common in children with cerebral palsy (CP). Hip dislocation develops in 15% and 20% of children with CP, mainly between three and six years of age and especially in the spastic and dyskinetic subtypes. The risk of scoliosis increases with age and increasing disability as expressed by the Gross Motor Function Score.METHODS:A hip surveillance programme and early surgical treatment have been shown to reduce the hip dislocation, but it remains unclear if a similar programme could reduce the need for neuromuscular scoliosis. When hip dislocation and neuromuscular scoliosis are co-existent, there appears to be no clear guidelines as to which of these deformities should be addressed first: hip or spine.RESULTS:Hip dislocation or windswept deformity may cause pelvic obliquity and initiate scoliosis, while neuromuscular scoliosis itself leads to pelvic obliquity and may increase the risk of hip dislocation especially on the high side. It remains unclear if treating imminent hip dislocation can prevent development of scoliosis and vice versa, but they may present at the same time for surgery. Current expert opinion suggests that when hip dislocation and scoliosis present at the same time, scoliosis associated pelvic obliquity should be corrected before hip reconstruction. If the patient is not presenting with pelvic obliquity the more symptomatic condition should be addressed first.CONCLUSION:Early identification of hip displacement and neuromuscular scoliosis appears to be important for better surgical outcomes.</p

Induction of a representative idiopathic-like scoliosis in a porcine model using a multidirectional dynamic spring-based system

BACKGROUND CONTEXT: Scoliosis is a 3D deformity of the spine in which vertebral rotation plays an important role. However, no treatment strategy currently exists that primarily applies a continuous rotational moment over a long period of time to the spine, while preserving its mobility. We developed a dynamic, torsional device that can be inserted with standard posterior instrumentation. The feasibility of this implant to rotate the spine and preserve motion was tested in growing mini-pigs. PURPOSE: To test the quality and feasibility of the torsional device to induce the typical axial rotation of scoliosis while maintaining growth and mobility of the spine. STUDY DESIGN: Preclinical animal study with 14 male, 7 month old Gottingen mini-pigs. Comparison of two scoliosis induction methods, with and without the torsional device, with respect to 3D deformity and maintenance of the scoliosis after removal of the implants. METHODS: Fourteen mini-pigs received either a unilateral tether-only (n=6) or a tether combined with a contralateral torsional device (n=8). X-rays and CT-scans were made post-operative, at 8 weeks and at 12 weeks. Flexibility of the spine was assessed at 12 weeks. In 3 mini-pigs per condition, the implants were removed and the animals were followed until no further correction was expected. RESULTS: At 12 weeks the tether-only group yielded a coronal Cobb angle of 16.8±3.3°For the tether combined with the torsional device this was 22.0±4.0°. The most prominent difference at 12 weeks was the axial rotation with 3.6±2.8° for the tether-only group compared to 18.1±4.6° for the tether-torsion group. Spinal growth and flexibility remained normal and comparable for both groups. After removal of the devices, the induced scoliosis reduced by 41% in both groups. There were no adverse tissue reactions, implant complications or infections. CONCLUSION: The present study indicates the ability of the torsional device combined with a tether to induce a flexible idiopathic-like scoliosis in mini-pigs. The torsional device was necessary to induce the typical axial rotation found in human scoliosis. Clinical significance: The investigated torsional device could induce apical rotation in a flexible and growing spine. Whether this may be used to reduce a scoliotic deformity remains to be investigated

Gender differences in characteristics of violent and sexual victimization in patients with psychosis:a cross-sectional study

Abstract Introduction Various studies have demonstrated that individuals with a psychotic disorder are at an increased risk of becoming a victim of crime. Little is known about gender differences in victimization types and in specific characteristics of victimization (e.g., perpetrator, location or disclosure). Knowledge on characteristics of victimization would provide clinicians with more insight which may be especially useful for tailoring interventions. The aim of this study is to examine gender differences in characteristics of violent and sexual victimization in patients with a psychotic disorder. Methods Information on violent (threats, physical abuse) and sexual victimization (harassment, assault) was assessed in 482 individuals with a psychotic disorder who received mental health care. Patients were recruited through a routine outcome monitoring study and a clinical trial. Results Men reported more threats with violence (20.7% vs. 10.5%, x2 = 7.68, p = 0.01), whereas women reported more sexual assault (13.3% vs. 3.6%, x2 = 15.43, p < 0.001). For violent victimization, women were more likely than men to be victimized by a partner, friend or family member (52.9% vs. 30.6%) as opposed to a stranger (11.8% vs. 40.3%; O.R. = 52.49) and to be victimized at home (60.0% vs. 29.3%) as opposed to on the street or elsewhere (40.0% vs. 70.3%; O.R. = 0.06). For sexual victimization, there was no difference in location and perpetrator between men and women. For sexual victimization and physical violence, no differences in disclosure were found, but women were more likely not to disclose threats with violence or to disclose threats to a professional or police (52.9% vs. 45.2%; O.R. = 30.33). All analyses were controlled for age, diagnosis and employment. Discussion Gender patterns of victimization types and characteristics are similar for individuals with a psychotic disorder in comparison to the general population. Men were at higher risk of violent victimization, whereas women were at higher risk for sexual victimization. Men were more likely to become victimized in the streets or elsewhere by a stranger, whereas women seemed to be more often victimized at home by a partner, friend or a family member. Future studies may tailor interventions preventing victimization in psychosis according to gender

Clinical, societal and personal recovery in schizophrenia spectrum disorders across time:States and annual transitions

BACKGROUND: Recovery in schizophrenia is a complex process, involving clinical, societal and personal recovery. Until now, studies analysed these domains separately, without examining their mutual relations and changes over time. AIMS: This study aimed to examine different states of recovery and transition rates between states. METHOD: The Pharmacotherapy Monitoring and Outcome Survey (2006–2017) yearly assesses patients with schizophrenia in the Northern Netherlands. Data from 2327 patients with one up to 11 yearly measurements on clinical, societal and personal recovery were jointly analysed with a mixture latent Markov model (MLMM). RESULTS: The selected MLMM had four states that differed in degree and pattern of recovery outcomes. Patients in state 1 were least recovered on any domain (16% of measurements), and partly recovered in states 2 (25%; featured by negative symptoms) and 3 (21%; featured by positive symptoms). Patients in state 4 (38%) were most recovered, except for work, study and housekeeping. At the subsequent measurement, the probability of remaining in the same state was 77–89%, transitioning to a better state was 4–12% and transitioning to a worse state was 4–6%; no transitions occurred between states 1 and 4. Female gender, shorter illness duration and less schizophrenia were more prevalent in better states. CONCLUSIONS: Quite a high recovery rate was present among a substantial part of the measurements (38%, state 4), with a high probability (89%) of remaining in this state. Transition rates in the other states might increase to a more favourable state by focusing on adequate treatment of negative and positive symptoms and societal problems
