Comparison of temporal changes in psychological distress after hematopoietic stem cell transplantation among the underlying diseases of Japanese adult patients

L-carnosine as an enhancer to computerized cognitive behaviour therapy in Japanese workers, an unjustified claim

This letter comments on the conclusion drawn by Shirotsuki et al. (2017) in their article entitled “The effect for Japanese workers of a self-help computerized cognitive behaviour therapy program with a supplement soft drink”, recently published in BioPsychoSocial Medicine. The authors concluded that their drink, containing L-carnosine, enhances the effects of a computerized cognitive-behavioural therapy (CCBT) on the psychological well-being of healthy Japanese workers. Yet, we argue that their conclusion is unfounded given their results and the methodological shortcomings of their study. Briefly, while the authors reported improvement on the tension-anxiety subscale of the Profile of Mood States (POMS) in the CCBT only group, they also observed a lack of improvement on this subscale in the CCBT+L-carnosine group suggesting that the drink washes out this beneficial effect of CCBT. Methodological issues include the uncontrolled levels of L-carnosine metabolized by participants jeopardize the study’s internal validity. Also, the clinical meaningfulness of the findings seems dubious as post-treatment scores remained within the range of the general Japanese population. Consequently, we argue that Shirotsuki et al.’s study should be re-conducted before drawing any valid conclusion.

The experiences of protective isolation in patients undergoing bone marrow or haematopoietic stem cell transplantation: systematic review and metasynthesis

Protective isolation is aimed at preventing infection in neutropenic patients, but it is implemented inconsistently across centres and is supported by recommendations with poor evidence. This review and metasynthesis explored the experiences and the psychological implications of protective isolation in patients with haematological malignancies undergoing bone marrow (BMT) or haematopoietic stem cell transplantation (HSCT). A systematic search of multiple databases for qualitative studies exploring BMT or HSCT patients' experiences of protective isolation was completed. The metasynthesis followed the meta-aggregative method from the Joanna Briggs Institute, with four procedural steps: (1) comprehensive search, (2) quality appraisal, (3) extraction of relevant findings and (4) synthesis of the identified findings. Twenty-six findings were extracted from 11 articles included in the review. The synthesising process yielded seven categories, aggregated into three synthesised findings: (1) isolation is a source of suffering, (2) isolation can lead to relating with oneself and (3) the person does not close the door to the outside world. This metasynthesis sheds light on patients' suffering from being isolated, and the possibility of overcoming this suffering thanks to relationships that patients have with themselves and with the external world. Healthcare providers should reconsider this practise in order to avoid unnecessary patient suffering.

A prospective study of the relationship between sense of coherence, depression, anxiety, and quality of life of haematopoietic stem cell transplant patients over time

OBJECTIVES

The primary aim of this study was to examine the impact of patient sense of coherence (SOC) on anxiety and depressive symptoms, and quality of life (QoL) dimensions in the acute phase of haematopoietic stem cell transplantation (HSCT). A secondary aim was to determine if SOC measured pre-transplant was predictive of psychological distress and QoL post-transplantation, after controlling for physical wellbeing.

METHOD

A series of measures was completed by 60 HSCT patients prior to transplantation. Follow-up data were collected at 2-3 weeks and 3 months post-transplantation. Measures administered included the Brief Symptom Inventory-18, Orientation to Life Questionnaire, and Functional Assessment of Cancer Therapy-Bone Marrow Transplantation.

RESULTS

When compared across the three time points, depression levels, and physical and functional wellbeing were worst at 2-3 weeks post-transplantation. SOC was positively associated with physical wellbeing prior to HSCT but not after transplantation. Weaker SOC predicted higher levels of depression, and poorer social, emotional, and functional wellbeing at both follow-up points, after accounting for physical wellbeing.

CONCLUSIONS

Given that SOC was related to depression and QoL dimensions post-transplantation, it may be important for health care professionals to conduct psychosocial assessments to determine patient SOC. This would enable provision of tailored psychological support prior to and following stem cell transplantation.

Sleep disturbances in patients with chronic pain: effectively managing opioid analgesia to improve outcomes

BACKGROUND

Many patients with chronic pain experience pain-related sleep disturbances, such as difficulty falling and staying asleep and less restful sleep. Evidence suggests that pain and sleep exist in a bidirectional relationship in which pain causes sleep disturbance and sleep disturbance intensifies pain. This association can impair a patient's daily function and decrease quality of life. Evidence suggests that patients with chronic pain can use opioid analgesics or other pain medications to control their pain and, in turn, improve some measures of sleep. This may include subjective sleep measures such as increased sleep time, and, as evidenced in recent studies, objective sleep measures such as sleep efficiency.

SCOPE

The role of effective analgesia in the improvement of pain-related sleep disturbance is discussed herein, specifically the risks and benefits of opioid therapy for the treatment of patients with chronic pain and disturbed sleep. MEDLINE and PubMed searches were conducted to locate relevant studies dated from January 1975 to April 2008. English-only randomized controlled trials and nonrandomized studies were considered.

FINDINGS

Numerous studies support the benefits of effective analgesia with opioid therapy on sleep.

CONCLUSION

Pain control achieved with pharmacotherapy, specifically opioid therapy, may help to improve sleep in patients for which opioid therapy is appropriate.
