Development of a multiplex TaqMan real-time PCR assay for the detection of Chlamydia psittaci and Chlamydia pneumoniae in human clinical specimens

Diagnosis of Chlamydia psittaci and Chlamydia pneumoniae infections has traditionally relied on serological assays. We developed a multiplex real-time PCR assay for detection of C. psittaci, C. pneumoniae and an internal control. Results of this assay demonstrated 100% concordance compared to results of previously tested human clinical specimens.     

Recovery concept in a Norwegian setting to be examined by the assertive community treatment model and mixed methods

Recovery is a crucial concept in the mental health field. The research of recovery is split into the categories of personal, social and clinical recovery. The purpose of this study was to explore the fragmented concept of recovery in light of assertive community treatment (ACT) in Norway. The study has a mixed methods design with a pragmatic approach. The Questionnaire about the Process of Recovery and open‐ended questions posed to 70 participants from 12 ACT teams in Norway, gathered by the “Users interview users” method, are combined with interviews or focus groups with eight of these participants. Surprisingly those under a community treatment order (CTO) report the highest degree of personal recovery. The qualitative material shows that the service users interpreted the concept of recovery differently than researchers and professionals. The ACT service users highlighted three important elements: flexible treatment, medication and access to a car. They emphasized the necessity for basic needs to be met in order to experience a meaningful recovery process, and these basic needs may be of even greater importance to those under CTOs. Their experiences should imply a greater emphasis on securing basic needs such as secure housing, sounder finances and access to the normal benefits offered by society.     

Psychotic Experiences,Childhood Trauma,and Alcohol-Related Self-Efficacy in a Nonpsychiatric Sample of Individuals in Alcohol Dependence Treatment: A Pilot Study

There is a substantial co-occurrence between alcohol dependence and psychiatric symptoms. Moreover, research suggests that such symptoms, including psychotic experiences, are continuously distributed in the population. There is a lack of research concerning psychotic symptoms in otherwise non-psychiatric populations with alcohol dependence. The aim of this study was to investigate the prevalence of psychotic symptoms in this population, and to relate this to childhood trauma and management of alcohol dependence. From a population with alcohol dependence two sub-groups were extracted, with low and high levels of psychotic experiences respectively. These were compared concerning childhood trauma and management of dependence using ANOVA, and the resulting model was examined using binary logistic regression. There was a sub-group of 14,3% of the population with elevated levels of psychotic experiences. This group displayed higher degree of self-reported childhood trauma as well as difficulties in managing alcohol dependence, when compared to a sub-group with low levels of psychotic experiences. There may be a substantial sub-group in the otherwise non-psychiatric population with alcohol dependence, with significant difficulties concerning psychotic symptoms, trauma and management of dependence, where anxiety may have a mediating function. If so, this group calls for broader assessment and treatment than standard alcohol interventions.     

Editorial Commentary: Is Posterior Distal Clavicle Beveling for Chronic Nonincarcerated Type IV Acromioclavicular Separation a Sufficient Treatment?

While low-grade acromioclavicular injuries can be managed nonoperatively, high-grade separations may result in persistent pain or functional decline and require surgical intervention. The authors of “Posterior Distal Clavicle Beveling for Chronic Nonincarcerated Type IV Acromioclavicular Separations: Surgical Technique and Early Clinical Outcomes” present a case series reporting convincing results concerning functional outcomes and early return-to-sport rates for this rather rare condition. While this technique seemed to work well in this small series of patients, in our opinion, this procedure should be reserved for use in exceptional cases only.     

Individualized 6‐mercaptopurine increments in consolidation treatment of childhood acute lymphoblastic leukemia: A NOPHO randomized controlled trial

Objectives

This randomized controlled trial tested the hypothesis that children with non‐high‐risk acute lymphoblastic leukemia could benefit from individualized 6‐mercaptopurine increments during consolidation therapy (NCT00816049). Primary and secondary end points were end of consolidation minimal residual disease (MRD) positivity and event‐free survival.

Methods

392 patients were randomized to experimental and 396 to standard therapy. Patients allocated to standard therapy received oral 6‐mercaptopurine (25 mg/m²/day) from days 30 to 85, while the experimental arm received stepwise increments of additional 25 mg/m²/day beginning on days 50 and/or 71 unless dose‐limiting myelosuppression had occurred.

Results

In the experimental arm, 166 patients (42%) received one dose increment, and 62 (16%) received two. Fifty‐seven of 387 (15%) patients in the experimental arm were MRD positive at end of consolidation vs 77 of 389 (20%) in the control arm (P = .08). Five‐year probability of event‐free survival was 0.89 (95% CI: 0.85‐0.93) in the experimental arm vs 0.93 (0.90‐0.96) in the control arm (P = .13). The median accumulated length of 6‐mercaptopurine treatment interruptions was 7 (IQR 2‐12) in the experimental arm vs 4 (IQR 0‐10) in the control arm (P = .002).

Conclusion

This study found no benefit from individualized 6‐mercaptopurine increments compared to standard therapy.
