Borderline personality disorder and the diagnostic co-occurrence of mental health disorders and somatic diseases: A controlled prospective national register-based study.

OBJECTIVE: Information on borderline personality disorder (BPD) and its comorbidities is often limited to concentrate on a few diagnoses. The aim of the study was to use national register data to investigate all diagnostic co-occurring mental health disorders and somatic diseases 3 years before and after initial BPD diagnosis compared with a matched control group. METHOD: The study was a register-based cohort of 2756 patients with incident BPD (ICD F60.3) and 11,024 matched controls, during 2002-2016. Comorbidity data were classified into main disease groups, in accordance with the World Health Organization ICD-10 criteria. RESULTS: Almost half the patients had been diagnosed with mental and behavioral disorders before the BPD diagnosis as compared to 3% in the control group. Further, the co-occurrence of diseases due to external causes of morbidity, including injury, self-harm, and poisoning were more represented in the BPD group before diagnosis as compared to the control group. In addition, co-occurring morbidity related to diseases in the circulatory, the respiratory, the digestive, the musculoskeletal, and the genitourinary system was more represented in the BPD group. After diagnosis, the proportion of patients with co-occurring morbidity increased further in all main disease groups in the BPD group. As many as 87% of patients had mental and behavioral co-occurring morbidity and 15% nervous diseases as compared with 3% and 4%, respectively, in the control group. Also, comorbidities related to external causes of morbidity, including for example, injury and self-harm were more represented in the BPD group. The BPD group had more somatic co-occurring morbidity, especially digestive, respiratory, circulatory, and endocrine diseases. Finally, the mortality over 12 years was statistically significantly higher in people with BPD than in the control group. CONCLUSION: Patients with BPD have higher odds for multiple physical health conditions and co-occurrence of mental health disorders.

Music therapy was noninferior to verbal standard treatment of traumatized refugees in mental health care: Results from a randomized clinical trial.

Background: Many people with refugee backgrounds suffer from trauma-related complex social and psychological problems, and compliance with standard psychological treatment tends to be low. More culturally adaptable treatment options seem to be needed. Objective: We aimed to investigate whether the music therapy method: 'trauma-focused music and imagery' (tr-MI), characterized by a particular focus on arousal and affect regulation, would be equally effective as the standard psychological talk therapies for ameliorating trauma symptoms in Danish refugees. Methods: A pragmatic, noninferiority, parallel, randomized controlled trial with six-month follow-up was carried out at three clinics for refugees in the public mental health services of the Psychiatry (DK). Seventy-four adults diagnosed with posttraumatic stress disorder (PTSD) were allocated to either music therapy sessions (tr-MI, N = 39) or psychological treatment as usual (TAU, N = 35). Western classical music, new age music, and music from the participants' own national culture were used to generate inner imagery, following a phased treatment protocol. Homework entailed listening to music. The primary outcome was the measurement of trauma symptoms by the Harvard Trauma Questionnaire, section IV (HTQ-IV); secondary measures were somatoform and psychoform dissociation (DSS-20), SDQ-20), attachment (RAAS), and well-being (WHO-5). Treatment effects reflected by primary and secondary measures were estimated using linear mixed models. Results: Tr-MI was noninferior to TAU (mean difference at follow-up HTQ-IV: 0.14, CI (-0.10; 0.38), with a - 0.3 noninferiority margin). A high dropout rate of 40% occurred in the TAU group, compared to 5% in the music therapy group. Secondary measures generated small to medium effect sizes in both groups, with significant medium effect sizes for well-being and psychoform dissociation at follow-up in tr-MI. Conclusions: Tr-MI is an innovative form of psychological treatment in refugee mental health services. Trials comparing music therapy to standardized therapy are needed to substantiate the evidence base for tr-MI therapy.

Antecedentes: Muchas personas con antecedente de condición de refugiadas sufren complejos problemas psicológicos y sociales relacionados con el trauma, y el cumplimiento con el tratamiento psicológico estándar tiende a ser bajo. Parecen ser necesarias opciones de tratamiento más culturalmente adaptadas.Objetivo: Apuntamos a investigar si el método de músico-terapia: 'música e imaginería focalizada en el trauma' (tr-MI), caracterizado por un enfoque particular en el nivel de alerta y regulación emocional, podría ser igualmente efectivo como las terapias psicológicas de conversación para aliviar síntomas de trauma en refugiados daneses.Métodos: Se llevó a cabo un ensayo clínico aleatorizado controlado, pragmático, de no inferioridad, paralelo, con seis meses de seguimiento en tres clínicas para refugiados en servicios públicos de salud mental de Psiquiatría en Dinamarca. Setenta y cuatro adultos diagnosticados con Trastorno de estrés postraumático (TEPT) fueron asignados a sesiones de músico-terapia (tr-MI, N = 39) o al tratamiento psicológico de costumbre (TAU, N = 35). Se utilizó música clásica occidental, música new age, y música de la propia cultura nacional de los participantes, para generar imaginería interior, siguiendo un protocolo de tratamiento por fases. La tarea implicaba escuchar música. El resultado principal fue la medición de síntomas de trauma a través del Cuestionario de Trauma de Harvard, sección IV (HTQ-IV); las mediciones secundarias fueron disociación somatomorfa y psicomorfa (DSS-20, SDQ-20), apego (RAAS), y bienestar (WHO-5). Los efectos del tratamiento reflejados por mediciones primarias y secundarias fueron estimados usando modelos lineales mixtos.Resultados: Tr-MI no fue inferior a TAU (diferencia promedio al seguimiento HTQ-IV: 0.14, IC −0.10; 0.38), con un margen de no-inferioridad de −0.3). Una alta tasa de deserción de un 40% ocurrió en el grupo TAU, comparado con un 5% en el grupo de músico-terapia. Las mediciones secundarias generaron tamaños de efecto pequeños a medianos en ambos grupos, con un tamaño del efecto mediano significativo para bienestar y disociación psicomorfa al seguimiento en tr-MI.Conclusiones: Tr-MI es una forma innovadora de tratamiento psicológico en servicios de salud mental para refugiados. Se necesitan ensayos comparando músico-terapia con terapia estandarizada para probar la base de evidencia para la terapia tr-MI.

Therapists' Perceptions of Individual Patient Characteristics that May Be Hindering to Group CBT for Anxiety and Depression.

Objective: Individual patient characteristics are important in trying to understand why people respond differently to group CBT. Only a few studies have explored therapists' perceptions of within-patient attributes that may be hindering in group CBT in a mental health setting. Method: We explored the perception of individual patient characteristics and related obstacles in 12 psychotherapists in Danish Mental Health Services through semi-structured interviews. The interviews were analyzed using a descriptive qualitative framework. Results: The results revealed four distinct themes that the therapists pointed to as important for the outcome of a 14-week group CBT intervention for social phobia, panic disorder, agoraphobia and major depressive disorder. The four themes were Complexity & severity, External circumstances, Attitudes & coping and Cognitive ability & reflection level. The therapists explained how they perceived higher complexity and severity in the patients as an obstacle, they highlighted that a calm and stable outside environment aided therapeutic change, whilst stressors were hindering. They perceived active coping mechanisms, positive attitudes and high readiness to change as positive factors, whilst dependent and hostile coping mechanisms and negative attitudes were seen as obstacles. Finally, the therapists pointed to cognitive abilities and reflection level, explaining how it could be difficult to obtain good outcomes for patients who's cognitive abilities were debilitated due to psychopathological factors or for patients with a generally low reflection level. Conclusions: The results indicated that the therapists experience group CBT as an intervention that requires certain prerequisites of the patients, and that the four themes should be considered when deciding on treatment options for any given patient. The clinical utility and theoretical implications of the results are discussed.

Traumatic experiences, ICD-11 PTSD, ICD-11 complex PTSD, and the overlap with ICD-10 diagnoses.

OBJECTIVES: This study investigated the frequency of traumatic experiences, prevalence rates of ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD), and overlap with ICD-10 classified disorders in outpatient psychiatry. METHOD: Overall, 165 Danish psychiatric outpatients answered the International Trauma Questionnaire, the Life Event Checklist, and the World Health Organization Well-being Index. ICD-10 diagnoses were extracted from the hospital record. Chi-square analysis, t-tests, and conditional probability analysis were used for statistical analysis. RESULTS: Nearly, all patients (94%) had experienced at least one traumatic event. CPTSD (36%) was more common than PTSD (8%) and had considerable overlap with ICD-10 affective, anxiety, PTSD, personality, adjustment and stress-reaction disorders, and behavioural and emotional disorders with onset usually occurring in childhood and adolescence. ICD-11 PTSD overlapped with ICD-10 anxiety, PTSD, adjustment and stress-reaction disorders, and behavioural and emotional disorders with onset usually occurring in childhood and adolescence. A subgroup of patients with ICD-10 PTSD (23%) did not meet criteria for ICD-11 PTSD or CPTSD. CONCLUSION: Traumatic experiences are common. ICD-11 CPTSD is a highly prevalent disorder in psychiatric outpatients. One quarter with ICD-10 PTSD did not meet criteria for either ICD-11 PTSD or CPTSD. PTSD and CPTSD had considerable overlap with ICD-10 disorders.

Societal costs of Borderline Personality Disorders: a matched-controlled nationwide study of patients and spouses.

OBJECTIVE: Information on societal cost of patients with Borderline Personality Disorder (BPD) and spouses is limited. The aim was to investigate factual societal costs before and after initial BPD diagnosis. METHOD: A register-based cohort study of 2756 patients with incident BPD (ICD F60.3) with spouses and 11 024 matched controls, during 2002-2016. RESULTS: Total direct healthcare costs and lost productivity costs amounted €40 441 for patients with BPD, which was more than 16 times higher than the matched controls. Somatic and psychiatric health care costs and costs of lost productivity were increased during 5 years before initial diagnosis of BPD. Before and after initial diagnosis, health care costs and lost productivity were increased among spouses of patients with BPD. CONCLUSION: Patients with BPD differed substantially from the general population with respect to all included costs. The study documented a significant burden on their spouses. Besides the early onset of BPD, which implies that patients are affected before they finish school and enter labor market, the neurocognitive impairment and fundamental symptoms of BPD, e.g. unstable, intense relationships, impulsivity, and lack of stable sense of self together with psychiatric and somatic comorbidity are part of explanation of the excess costs of BPD.

Probable Post-traumatic Stress Disorder and Self-harming Behaviour: Potential Barriers to Employment?

The current study screened for post-traumatic stress disorder (PTSD) and self-harming behaviours, often related to borderline personality disorder (BPD), among individuals in a job centre considered unemployable primarily for psychological reasons. Participants (N = 112) filled in questionnaires on PTSD symptoms (n = 62) and self-harming behaviours (n = 59) as part of participating in team-meetings providing the individuals with a return-to-work plan. Differences in demographic variables between individuals with and without valid protocols were small to moderate. Of the individuals filling in the PTSD questionnaire 40% fulfilled criteria for probable PTSD and 31% of the individuals filling in the questionnaire on self-harming behaviours reported five or more types of self-harming behaviours. Only a minority of these individuals had PTSD or BPD respectively mentioned in their case records. Further investigation of the prevalence of PTSD and self-harming behaviour among individuals considered unemployable is warranted as well as an enhanced focus in jobcentres and other institutions supporting employability on detection and treatment of PTSD and early signs of BPD.

Deriving ICD-11 personality disorder domains from dsm-5 traits: initial attempt to harmonize two diagnostic systems.

OBJECTIVE: The personality disorder domains proposed for the ICD-11 comprise Negative Affectivity, Detachment, Dissociality, Disinhibition, and Anankastia, which are reasonably concordant with the higher-order trait domains in the Alternative DSM-5 Model for Personality Disorders. METHOD: We examined (i) whether designated DSM-5 trait facets can be used to describe the proposed ICD-11 trait domains, and (ii) how these ICD-11 trait features are hierarchically organized. A mixed Danish derivation sample (N = 1541) of 615 psychiatric out-patients and 925 community participants along with a US replication sample (N = 637) completed the Personality Inventory for DSM-5 (PID-5). Sixteen PID-5 traits were designated to cover features of the ICD-11 trait domains. RESULTS: Exploratory structural equation modeling (ESEM) analyzes showed that the designated traits were meaningfully organized in the proposed ICD-11 five-domain structure as well as other recognizable higher-order models of personality and psychopathology. Model fits revealed that the five proposed ICD-11 personality disorder domains were satisfactorily resembled, and replicated in the independent US sample. CONCLUSION: The proposed ICD-11 personality disorder domains can be accurately described using designated traits from the DSM-5 personality trait system. A scoring algorithm for the ICD-11 personality disorder domains is provided in appendix.

Intra-subject variability in muscle activity and co-contraction during jumps and landings in children and adults.

We investigated muscle activity, intra-subject variability in muscle activity and co-contraction during vertical jumps and landings in children and adults. Ten male children and 10 male adults completed 10 countermovement jumps (CMJ), 10 drop jumps (DJ) from 30 cm, 10 low and high landings from 30 and 60 cm for the children and 60 and 90 cm for the adults. The adults also performed ten DJ from 60 cm. EMG was recorded from nine lower limb muscles in the right leg and normalized to isometric MVC. Statistical parametric mapping was used to reveal differences in the muscle activity and intra-subject variability in the muscle activity. Co-contraction was quantified for two thigh muscle pairs and one plantar flexor/dorsiflexor muscle pair and group differences were assessed (two-way ANOVA). No significant differences were observed in the less eccentric demanding CMJ while significantly higher muscle activity magnitude and intra-subject variability were observed for the children during the initial part of the contact phase of DJ and landings, indicating a less consistent muscle activity pattern in the children. This may indicate that vertical jumps/landings involving a high amount of eccentric muscle contraction constrain the muscle activation in children, possibly because of immature motor control.

Evidence on methylphenidate in children and adolescents with ADHD is in fact of 'very low quality'.

Banaschewski and colleagues from the European Attention Deficit Hyperactivity Disorder (ADHD) guideline group make a number of critical comments regarding our systematic review on methylphenidate for children and adolescents with ADHD. In this article, we present our views, showing that our trial selection was not flawed and was undertaken with scientific justification. Similarly, our data collection and interpretation was systematic and correct. We have followed a sound methodology for assessing risk of bias and our conclusions are not misleading. We acknowledge that different researchers might make risk of bias judgments at higher or lower thresholds, but we have been consistent and transparent in applying our pre-defined and per reviewed protocol. Although we made minor errors, we demonstrate that the effects are negligible and not affecting our conclusions. We are happy to correct such errors and to engage in debate on methodological and ethical issues. In terms of clinical implications, we are advocating that clinicians, patients and their relatives should weight carefully risks and benefits of methylphenidate. Clinical experience seems to suggest that there are people who benefit from this medication. Our systematic review does, however, raise questions regarding the overall quality of the methylphenidate trials.

Utility of DSM-5 section III personality traits in differentiating borderline personality disorder from comparison groups.

OBJECTIVE: Borderline Personality Disorder (BPD) is a highly prevalent diagnosis in mental health care and includes a heterogeneous constellation of symptoms. As the field of personality disorder (PD) research moves to emphasize dimensional traits in its operationalization, it is important to determine how the alternative DSM-5 Section III personality trait dimensions differentiates such features in BPD patients versus comparison groups. To date, no study has attempted such validation. METHOD: The current study examined the utility of the DSM-5 trait dimensions in differentiating patients with the categorical DSM-IV/5 diagnosis of BPD (n=101) from systematically matched samples of other PD patients (n=101) and healthy controls (n=101). This was investigated using one-way ANOVA and multinomial logistic regression analyses. RESULTS: Results indicated that Emotional Lability, Risk Taking, and Suspiciousness uniquely differentiated BPD patients from other PD patients, whereas Emotional Lability, Depressivity, and Suspiciousness uniquely differentiated BPD patients from healthy controls. CONCLUSION: Emotional Lability is in particular a key BPD feature of the proposed Section III model, whereas Suspiciousness also augments essential BPD features. Provided that these findings are replicated cross-culturally in forthcoming research, a more parsimonious traits operationalization of BPD features is warranted.

Dynamic balance during gait in children and adults with Generalized Joint Hypermobility.

BACKGROUND: The purpose of the study was to investigate if differences of the head and trunk stability and stabilization strategies exist between subjects classified with Generalized Joint Hypermobility and healthy controls during gait. It was hypothesized that joint hypermobility could lead to decreased head and trunk stability and a head stabilization strategy similar to what have been observed in individuals with decreased locomotor performance. METHODS: A comparative study design was used wherein 19 hypermobile children were compared to 19 control children, and 18 hypermobile adults were compared to 18 control adults. The subjects were tested during normal walking and walking on a line. Kinematics of head, shoulder, spine and pelvis rotations were measured by five digital video cameras in order to assess the segmental stability (angular dispersion) and stabilization strategies (anchoring index) in two rotational components: roll and yaw. FINDINGS: Hypermobile children and adults showed decreased lateral trunk stability in both walking conditions. In hypermobile children, it was accompanied with decreased head stability as the head was stabilized by the inferior segment when walking on a line. Several additional differences were observed in stability and stabilization strategies for both children and adults. INTERPRETATION: Stability of the trunk was decreased in hypermobile children and adults. This may be a consequence of decreased stability of the head. Hypermobile children showed a different mode of head stabilization during more demanding locomotor conditions indicating delayed locomotor development. The findings reflect that Generalized Joint Hypermobility probably include motor control deficits.

Effects of cognitive therapy versus interpersonal psychotherapy in patients with major depressive disorder: a systematic review of randomized clinical trials with meta-analyses and trial sequential analyses.

BACKGROUND: Major depressive disorder afflicts an estimated 17% of individuals during their lifetime at tremendous suffering and cost. Cognitive therapy and interpersonal psychotherapy are treatment options, but their effects have only been limitedly compared in systematic reviews. METHOD: Using Cochrane systematic review methodology we compared the benefits and harm of cognitive therapy versus interpersonal psychotherapy for major depressive disorder. Trials were identified by searching the Cochrane Library's CENTRAL, Medline via PubMed, EMBASE, Psychlit, PsycInfo, and Science Citation Index Expanded until February 2010. Continuous outcome measures were assessed by mean difference and dichotomous outcomes by odds ratio. We conducted trial sequential analysis to control for random errors. RESULTS: We included seven trials randomizing 741 participants. All trials had high risk of bias. Meta-analysis of the four trials reporting data at cessation of treatment on the Hamilton Rating Scale for Depression showed no significant difference between the two interventions [mean difference -1.02, 95% confidence interval (CI) -2.35 to 0.32]. Meta-analysis of the five trials reporting data at cessation of treatment on the Beck Depression Inventory showed comparable results (mean difference -1.29, 95% CI -2.73 to 0.14). Trial sequential analysis indicated that more data are needed to definitively settle the question of a differential effect. None of the included trial reported on adverse events. CONCLUSIONS: Randomized trials with low risk of bias and low risk of random errors are needed, although the effects of cognitive therapy and interpersonal psychotherapy do not seem to differ significantly regarding depressive symptoms. Future trials should report on adverse events.

Is it possible to reduce the knee joint compression force during level walking with hiking poles?

Walking with hiking poles has become a popular way of exercising. Walking with poles is advocated as a physical activity that significantly reduces the loading of the hip, knee and ankle joints. We have previously observed that pole walking does not lead to a reduction of the load on the knee joint. However, it is unclear whether an increased force transmitted through the poles can reduce the load on the knee joint. Thus, the purpose of the present study was to investigate if an increased load transmitted through the arms to the poles could reduce the knee joint compression force during level walking with poles. We hypothesized that an increased pole force would result in a reduction of the knee joint compression force. Gait analyses from 10 healthy subjects walking with poles were obtained. The pole force was measured simultaneously during the gait analyses. The knee joint compression forces were estimated by using a biomechanical knee joint model. The results showed that the subjects were able to increase the pole force by 2.4 times the normal pole force. However, this did not lead to a reduction in the knee joint compressive force and we rejected our hypothesis. In conclusion, the use of poles during level walking does not seem to reduce knee joint compressive loads. However, it is possible that the use of poles in other populations (e.g. osteoarthritis patients) and in terrain would unload the knee joint. This should be investigated in the future.

Early detection of psychosis: positive effects on 5-year outcome.

BACKGROUND: During the last decades we have seen a new focus on early treatment of psychosis. Several reviews have shown that duration of untreated psychosis (DUP) is correlated to better outcome. However, it is still unknown whether early treatment will lead to a better long-term outcome. This study reports the effects of reducing DUP on 5-year course and outcome. METHOD: During 1997-2000 a total of 281 consecutive patients aged >17 years with first episode non-affective psychosis were recruited, of which 192 participated in the 5-year follow-up. A comprehensive early detection (ED) programme with public information campaigns and low-threshold psychosis detection teams was established in one healthcare area (ED-area), but not in a comparable area (no-ED area). Both areas ran equivalent treatment programmes during the first 2 years and need-adapted treatment thereafter. RESULTS: At the start of treatment, ED-patients had shorter DUP and less symptoms than no-ED-patients. There were no significant differences in treatment (psychotherapy and medication) for the 5 years. Mixed-effects modelling showed better scores for the ED group on the Positive and Negative Syndrome Scale negative, depressive and cognitive factors and for global assessment of functioning for social functioning at 5-year follow-up. The ED group also had more contacts with friends. Regression analysis did not find that these differences could be explained by confounders. CONCLUSIONS: Early treatment had positive effects on clinical and functional status at 5-year follow-up in first episode psychosis.

Are multi family groups appropriate for patients with first episode psychosis? A 5-year naturalistic follow-up study.

OBJECTIVE: To compare outcome over 5 years for patients who participated in multi family groups (MFGs) to those who refused or were not offered participation. METHOD: Of 301 first episode psychotic patients aged 15-65 years, 147 participated in MFGs. Outcome was measured by drop-out rates, positive and negative syndrome scale (PANSS) symptom scores, and duration of psychotic episodes during the follow-up period. RESULTS: Multi family group participants had a significantly lower drop-out rates at 5-year follow-up than patients who did not participate. However, the MFG participants had significantly less improvement in PANSS positive and excitative symptoms and had significantly longer duration of psychotic symptoms during the follow-up period. CONCLUSION: Multi family groups appear to increase the chance of retaining patients in a follow-up study, but adjustment of the programme may be necessary with first episode psychosis patients to meet their needs better.

A 2-year follow-up of involuntary admission's influence upon adherence and outcome in first-episode psychosis.

OBJECTIVE: To see, if voluntary admission for treatment in first-episode psychosis results in better adherence to treatment and more favourable outcome than involuntary admission. METHOD: We compared consecutively first-admitted, hospitalised patients from a voluntary (n = 91) with an involuntary (n = 126) group as to psychopathology and functioning using Positive and Negative Syndrome Scale and Global Assessment of Functioning Scales at baseline, after 3 months and at 2 year follow-up. Moreover, duration of supportive psychotherapy, medication and number of hospitalisations during the 2 years were measured. RESULTS: More women than men were admitted involuntarily. Voluntary patients had less psychopathology and better functioning than involuntary patients at baseline. No significant difference as to duration of psychotherapy and medication between groups was found. No significant difference was found as to psychopathology and functioning between voluntarily and involuntarily admitted patients at follow-up. CONCLUSION: Legal admission status per se did not seem to influence treatment adherence and outcome.

Baseline profiles of adolescent vs. adult-onset first-episode psychosis in an early detection program.

OBJECTIVE: Psychotic disorders often start in adolescence. We aim to investigate premorbid and baseline differences characterizing patients with an onset of psychosis in adolescence versus adulthood. METHOD: We compare first-episode, DSM-IV non-affective psychosis with onset before (n = 43) and after (n = 189) 18 years on duration of untreated psychosis (DUP), level of symptoms, suicidal behaviour, and other baseline clinical and demographic characteristics. RESULTS: Adolescent onset patients had poorer premorbid functioning, a longer DUP, higher suicidality, and more depressive symptoms. They also had better cognition, fewer psychotic symptoms, and were more likely to be treated on an out-patient basis. CONCLUSION: Adolescents with first-episode psychosis may have a slower and more silent, i.e. insidious onset, and are at risk of experiencing longer treatment delays than adults. They fit the description of what used to be labeled process (versus reactive) schizophrenia.

Experimental muscle pain during a forward lunge--the effects on knee joint dynamics and electromyographic activity.

OBJECTIVE: The purpose of this study was to investigate whether the knee joint dynamics during a forward lunge could be modulated by experimentally induced vastus medialis pain in healthy subjects. DESIGN: Randomised cross-over study. SETTING: Biomechanical movement laboratory. PARTICIPANTS: 20 healthy subjects were included. One subject was excluded during data collection. INTERVENTION: The subjects performed forward lunges before, during and 20 minutes after induction of experimental quadriceps muscle pain. Muscle pain was induced using hypertonic saline (5.8%) injected intramuscularly. Isotonic saline (0.9%) was used as control. MAIN OUTCOME MEASUREMENTS: Three-dimensional movement analyses were performed and inverse dynamics were used to calculate joint kinematics and kinetics for ankle, knee and hip joints. Electromyographic (EMG) signals of the hamstrings and quadriceps muscles were recorded. RESULTS: During and after pain, significant decreases in knee joint dynamics and EMG recordings were observed. CONCLUSION: The study shows that local pain in the quadriceps is capable of modulating movements with high knee joint dynamics. The results may have implications in the management of muscle pain and prevention of injuries during activities involving the knee joint.

Clinical epidemiologic first-episode psychosis: 1-year outcome and predictors.

OBJECTIVE: To describe 1-year outcome in a large clinical epidemiologic sample of first-episode psychosis and its predictors. METHOD: A total of 301 patients with first-episode psychosis from four healthcare sectors in Norway and Denmark receiving common assessments and standardized treatment were evaluated at baseline, at 3 months, and at 1 year. RESULTS: Substantial clinical and social improvements occurred within the first 3 months. At 1-year 66% were in remission, 11% in relapse, and 23% continuously psychotic. Female gender and better premorbid functioning were predictive of less severe negative symptoms. Shorter DUP was predictive for shorter time to remission, stable remission, less severe positive symptoms, and better social functioning. Female gender, better premorbid social functioning and more education also contributed to a better social functioning. CONCLUSION: This first-episode sample, being well treated, may be typical of the early course of schizophrenia in contemporary centers.
