Effect of exercise therapy in patients with hip osteoarthritis: A systematic review and cumulative meta-analysis.

Objective: To evaluate the existing evidence on the effect of exercise therapy in patients with hip osteoarthritis (OA) compared to no treatment and explore whether a further trial will change the current evidence. Design: Systematic review and cumulative meta-analysis using randomized controlled trials (RCT) to determine the effect on pain and function post-treatment, and at 6-9 months after treatment. Standardized mean difference (SMD) â€‹≤ â€‹-0.37 was considered clinically worthwhile. Extended funnel plots were used to simulate the impact of a new trial on the pooled effect size of pain and function. Results: 18 RCTs were included. Post-treatment we found a beneficial effect of exercise therapy on pain (SMD -0.38, 95% Confidence Interval (CI): 0.55 to -0.22) and function (SMD -0.31, 95% CI -0.49 to -0.11). A beneficial effect of exercise therapy on pain (SMD -0.23, 95% CI: 0.41 to -0.05) and function (SMD -0.29, 95% CI: 0.45 to -0.12) was found 6-9 months after treatment. Most effect estimates were small, and it is unclear whether these are clinically meaningful. Extended funnel plots and a simulation of a new trial showed that only a new trial with a larger effect than the current pooled effect or a trial including 74,843 participants would change the pooled effect estimate from an unclear to a clearly clinically worthwhile effect. Conclusions: We found a beneficial effect of exercise therapy on pain and function in hip OA. It is unlikely a new trial added to current evidence will change the conclusion.

Is collaborative care a key component for treating pregnant women with psychiatric symptoms (and additional psychosocial problems)? A systematic review.

Mental disorders during pregnancy are common, with long-lasting negative effects on mother and child. Treatment of these women is challenging, because of the high incidence of additional psychosocial problems and barriers on population and healthcare level. Collaborative care, collaboration between mental health and obstetric care professionals, may help to overcome these problems. The aim of this review is to review antenatal mental health interventions and analyse the impact of collaborative care. Two independent reviewers searched for RCT's in PubMed, Embase and PsycINFO. Trials studying the effect of psychological or pharmacological interventions on the mental health of pregnant women with psychiatric symptoms (and psychosocial problems) were eligible for inclusion. Two reviewers independently abstracted data and assessed study quality and risk of bias. Each study was scored on collaborative care criteria: multi-professional approach to patient care, structured management plan, scheduled patient follow-ups and enhanced interprofessional communication. Thirty-five studies were included. Most trials studied the effect of cognitive behavioural therapy and interpersonal psychotherapy on antenatal depression. Almost all interventions met at least one collaborative care criteria. Interventions were mostly provided by multiple professionals, but interprofessional communication rarely took place. Interventions that met more criteria did not more often show a positive effect on maternal mental health. There is lack of research on antenatal psychiatric disorders other than depressive and on long-term treatment outcomes. Collaborative care is partly implemented in most current interventions, but more trials (including interprofessional communication) are needed to be conclusive whether collaborative care is a key component in antenatal mental healthcare.

Think twice before starting a new trial; what is the impact of recommendations to stop doing new trials?

OBJECTIVES: In evidence-based medicine, we base our conclusions on the effectiveness of interventions on the results of high-quality meta-analysis. If a new randomized controlled trial (RCT) is unlikely to change the pooled effect estimate, conducting the new trial is a waste of resources. We evaluated whether recommendations not to conduct further RCTs reduced the number of trials registered for two scenarios. METHODS: Analysis of registered trials on the World Health Organisation (WHO) International Clinical Trials Registry Platform (ICTRP). We regarded trial protocols relevant if they evaluated the effectiveness of (1) exercise for chronic low back pain (LBP) and (2) cognitive behavioural therapy (CBT) for chronic pain. We calculated absolute and relative numbers and change of registered trials in a pre-set time window before and after publication of the recommendations, both published in 2012. RESULTS: We found 1,574 trials registered in the WHO trial registry for exercise in LBP (459 before 2012; 1,115 after) and 5,037 trials on chronic pain (1,564 before 2012; 3,473 after). Before 2012, 13 trials on exercise for LBP (out of 459) fit the selection criteria, compared to 42 trials (out of 1,115) after, which represents a relative increase of 33%. Twelve trials (out of 1,564) regarding CBT for chronic pain, fit the selection criteria before 2012 and 18 trials (out of 3,473) after, representing a relative decrease of 32%. We found that visibility, media exposure and strength of the recommendation were related to a decrease in registered trials. CONCLUSIONS: Recommendations not to conduct further RCTs might reduce the number of trials registered if these recommendations are strongly worded and combined with social media attention.

Responders to Exercise Therapy in Patients with Osteoarthritis of the Hip: A Systematic Review and Meta-Analysis.

The Outcome Measures in Rheumatology workgroup (OMERACT), together with the Osteoarthritis Research Society International (OARSI) developed the OMERACT-OARSI responder criteria. These criteria are used to determine if a patient with osteoarthritis (OA) 'responds' to therapy, meaning experiences a clinically relevant effect of therapy. Recently, more clinical OA trials report on this outcome and most OA trials have data to calculate the number of responders according to these criteria. A systematic review and meta-analysis were performed on the response to exercise therapy, compared to no or minimal intervention in patients with hip OA using the OMERACT-OARSI responder criteria. The literature was searched for relevant randomized trials. If a trial fit the inclusion criteria, but number of responders was not reported, the first author was contacted. This way the numbers of responders of 14 trials were collected and a meta-analysis on short term (directly after treatment, 12 trials n = 1178) and long term (6-8 months after treatment, six trials n = 519) outcomes was performed. At short term, the risk difference (RD) was 0.14 (95% confidence interval (CI) 0.06-0.22) and number needed to treat (NNT) 7.1 (95% CI 4.5-17); at long term RD was 0.14 (95% CI 0.07-0.20) and NNT 7.1 (95% CI 5.0-14.3). Quality of evidence was moderate for the short term and high for the long term. In conclusion, 14% more hip OA patients responded to exercise therapy than to no therapy.

Group-based multicomponent treatment to reduce depressive symptoms in women with co-morbid psychiatric and psychosocial problems during pregnancy: A randomized controlled trial.

BACKGROUND: Depressive symptoms in pregnant women, which are common and debilitating, are often co-morbid with other mental disorders (e.g. anxiety and personality disorders), and related to low socioeconomic status (SES). This situation may hamper treatment outcome, which has often been neglected in previous studies on the treatment of depression during pregnancy. We developed a new group-based multicomponent treatment (GMT) comprising cognitive behavioral therapy, psycho-education and body-oriented therapy and compared the effect on depressive symptoms with individual counseling (treatment as usual, TAU) in a heterogeneous group of pregnant women with co-morbid mental disorders and/or low SES. METHODS: An outpatient sample from a university hospital of 158 pregnant women who met DSM-IV criteria for mental disorders were included and 99 participants were randomized to GMT or TAU from January 2010 until January 2013. The Edinburgh Depression Scale (EDS) was used at baseline, every 5 weeks during pregnancy and as the primary outcome measure of depressive symptoms at 6 weeks postpartum. Secondary outcome measures included the clinician-reported Hamilton Depression Rating Scale (HDRS), obstetric outcomes and a 'Patient Satisfaction' questionnaire. RESULTS: 155 participants were included the intention-to-treat (ITT)-analysis. GMT was not superior above TAU according to estimated EDS (ß = 0.13, CI = - 0.46-0.71, p = 0.67) and HDRS scores (ß = - 0.39, CI = - 0.82-0.05, p = 0.08) at 6 weeks postpartum. There were no differences in secondary outcomes between the GMT and TAU, nor between the randomized condition and patient-preference condition. LIMITATIONS: The ability to detect an effect of GMT may have been limited by sample size, missing data and the ceiling effect of TAU. CONCLUSIONS: GMT is an acceptable treatment for a heterogeneous group of pregnant women with depressive symptoms and co-morbid mental disorders and/or low SES, but not superior to TAU. Further research should focus on understanding and treating co-morbid disorders and psychosocial problems during pregnancy.

Interventions to treat mental disorders during pregnancy: A systematic review and multiple treatment meta-analysis.

BACKGROUND: For women suffering from an antepartum mental disorder (AMD), there is lack of evidence-based treatment algorithms due to the complicated risk-benefit analysis for both mother and unborn child. We aimed to provide a comprehensive overview of pharmacological and non-pharmacological interventions to treat AMD and performed a meta-analysis of the estimated treatment effect on the psychiatric symptoms during pregnancy. METHODS: MedLine, PsycINFO and Embase databases were searched by two independent reviewers for clinical trials with a control condition on treatment of women with AMD, i.e. major depressive (MDD), anxiety, psychotic, eating, somatoform and personality disorders. We inventoried the effect of the treatment, i.e. decrease of psychiatric symptoms at the end of the treatment or postpartum. We adhered to the PRISMA-protocol. FINDINGS: Twenty-nine trials were found involving 2779 patients. Trials studied patients with depressive disorders (k = 28), and anxiety disorders (k = 1). No pharmacological trials were detected. A form of psychotherapy, like Cognitive Behavioural Therapy (g = -0.61; 95%CI:-0.73 to -0.49, I2 = 0%; k = 7) or Interpersonal Psychotherapy (g = -0.67; 95%CI:-1.27 to -0.07; I2 = 79%; k = 4), holds robust benefit for pregnant women with MDD. Body-oriented interventions (g = -0.43; 95%CI:-0.61 to -0.25; I2 = 17%; k = 7) and acupuncture (g = -0.43; 95%CI:-0.80 to -0.06; I2 = 0%; k = 2) showed medium sized reduction of depressive symptoms. Bright light therapy (g = -0.59; 95%CI:-1.25 to 0.06; I2 = 0%; k = 2), and food supplements (g = -0.51; 95%CI:-1.02 to 0.01; I2 = 20%; k = 3) did not show significant treatment effects. One study was found on Integrative Collaborative Care. CONCLUSIONS: This meta-analysis found a robust moderate treatment effect of CBT for MDD during pregnancy, and to a lesser extent for IPT. As an alternative, positive results were found for body-oriented interventions and acupuncture. No evidence was found for bright light therapy and food supplements. Only non-pharmacological trials on women with MDD were found. Research on a wider range of AMD is needed.

The prevalence and correlates of self-harm in pregnant women with psychotic disorder and bipolar disorder.

Women with severe mental illness are at increased risk of suicide in the perinatal period, and these suicides are often preceded by self-harm, but little is known about self-harm and its correlates in this population. This study aimed to investigate the prevalence of suicidal ideation and self-harm, and its correlates, in women with psychotic disorders and bipolar disorder during pregnancy. Historical cohort study using de-identified secondary mental healthcare records linked with national maternity data. Women pregnant from 2007 to 2011, with ICD-10 diagnoses of schizophrenia and related disorders, bipolar disorder or other affective psychoses were identified. Data were extracted from structured fields, natural language processing applications and free text. Logistic regression was used to examine the correlates of self-harm in pregnancy. Of 420 women, 103 (24.5 %) had a record of suicidal ideation during the first index pregnancy, with self-harm recorded in 33 (7.9 %). Self-harm was independently associated with younger age (adjusted odds ratio (aOR) 0.91, 95 % CI 0.85-0.98), self-harm in the previous 2 years (aOR 2.55; 1.05-6.50) and smoking (aOR 3.64; 1.30-10.19). A higher prevalence of self-harm was observed in women with non-affective psychosis, those who discontinued or switched medication and in women on no medication at the start of pregnancy, but these findings were not statistically significant in multivariable analyses. Suicidal thoughts and self-harm occur in a significant proportion of pregnant women with severe mental illness, particularly younger women and those with a history of self-harm; these women need particularly close monitoring for suicidality.

Unique case of pneumomediastinum due to penetrating injury to the mediastinum.

Pneumomediastinum is a rare condition, and mostly occurs following traumatic or iatrogenic tracheal and oesophageal perforation, but spontaneous pneumomediastinum has also been described. We report a case of a 17-year-old woman who presented with a penetrating neck wound after a fall down the stairs. She had an extensive pneumomediastinum without signs of tracheal or oesophageal laceration, rib fractures, pneumothorax or haematothorax. The contaminated wound was surgically explored and extensively lavaged. Prophylactic antibiotic treatment was given and the patient recovered without complications. Direct perforating trauma to the mediastinum is a severe entity, but can be treated by lavage and prophylactic antibiotic therapy.

Perceived sleep quality is worse than objective parameters of sleep in pregnant women with a mental disorder.

OBJECTIVE: Disturbed sleep during pregnancy is associated with adverse obstetric outcomes and less mental well-being. In pregnant women with a mental disorder, who frequently suffer from sleep problems, it is unknown whether predominantly objective or subjective sleep quality is more affected. To clarify this, we compared objective and subjective parameters of sleep quality between patients and healthy controls during pregnancy. METHODS: This observational study was embedded in an ongoing study among pregnant women with a mental disorder at the department of Psychiatry of Erasmus University Medical Center Rotterdam, the Netherlands. We compared 21 pregnant women with a confirmed mental disorder with 33 healthy controls (gestational age, 23-29 weeks). To measure objective parameters of sleep quality, all participants continuously wore a wrist actigraph for 7 days and nights. Subjective sleep quality was retrospectively assessed using the Pittsburgh Sleep Quality Index (PSQI) and on a daily basis with the Subjective Sleep Quality-scale (SSQ). Differences in parameters of sleep between patients and controls were tested using a multivariate linear regression analysis adjusted for parity, gestational age, educational level, and employment status. RESULTS: Objective parameters of sleep quality and subjective sleep quality as assessed by the PSQI did not differ significantly between patients and controls. Daily sleep reports showed that, relative to controls, patients had a significantly worse average SSQ-score (5.2 vs. 7.6, adjusted ß = 0.12, 95%CI = 0.03-0.53, p < 0.01). CONCLUSIONS: Our exploratory study suggests that perceived sleep quality reported on a daily basis by pregnant women with a mental disorder is worse than the sleep quality as measured by wrist actigraphy.
