Posaconazole for primary antifungal prophylaxis in patients with acute myeloid leukaemia or myelodysplastic syndrome during remission induction chemotherapy: A single-centre retrospective study in Korea and clinical considerations. Mycoses, 58, 565–571.
To examine the incidence and outcomes related to the treatment of invasive fungal infection (IFI) with posaconazole versus fluconazole prophylaxis
Records of patients undergoing remission induction chemotherapy were reviewed for data collection. Results of those who received fluconazole versus posaconazole antifungal prophylaxis were compared. Both agents were begun 1–2 days prior to chemotherapy and continued until the patients' absolute neutrophil count (ANC) was > 500/mm3.
The incidence of breakthrough IFIs and the use of empirical antifungal treatment were lower in those who received posaconazole (p < 0.001). Overall, IFI-related mortality was 1.9% in the posaconazole group compared to 12.1% in the fluconazole group (p = 0.028). No difference existed between groups in overall survival.
The findings suggest that posaconazole was more effective than early generation azoles for antifungal prophylaxis in at-risk patients with cancer.
The findings suggest that newer azoles may be more effective for antifungal prophylaxis in at-risk patients with cancer.

Effects of music relaxation video on pain and anxiety for women with gynaecological cancer receiving intracavitary brachytherapy: A randomised controlled trial. Journal of Research in Nursing, 20, 129–144.
To determine the effect of watching a music relaxation video on pain and anxiety in women diagnosed with gynecological cancer who were undergoing intra-cavitary brachytherapy
A music relaxation video was played four times for a total of 120 minutes during the first 44 hours of brachytherapy treatment, with monitoring of pain scores, opioid consumption, and perceived anxiety scores compared to usual nursing care during the same time period.
Women in the intervention group reported less pain. There was no difference in levels of opioid consumption between the intervention and control groups. Participants in the music viewing group indicated significantly reduced anxiety levels in analysis (p = 0.001).
Nurses and other medical personnel should consider using music relaxation videos to help reduce pain and anxiety during intracavitary brachytherapy and other procedures that may be uncomfortable. The intervention is non-invasive, with beneficial effects.
This non-invasive intervention could be nurse-driven without a physician’s order. Women undergoing brachytherapy must lie still in a shielded isolation room for 2-3 days with limitations on visitors, resulting in physical and psychological discomforts, including pain. This study shows that pain experiences may be lessened with music relaxation videos.

STUDY PURPOSE: To collect, review, and report on the current evidence on behavioral and educational interventions used to support family caregivers of patients who are receiving end-of-life care
TYPE OF STUDY: Systematic review
PHASE OF CARE: End-of-life care
APPLICATIONS: Palliative care
Educational and behavioral interventions for caregivers of patients with advanced cancer at the end of life appear to be effective. They are difficult to study because of high attrition rates, in part because of the point in the illness trajectory in which one is asked to participate. However, increasing evidence supports that these types of interventions will benefit caregiver competence and well-being. Ongoing study is needed to identify more specifics about the interventions, what makes them successful, and the methods of delivery, the timing, and the dose, as well as what outcomes should be measured and with what instruments. Perhaps some consistency should be developed. The cost-effectiveness of interventions should be considered as well.
Educational and behavioral interventions for caregivers appear to be helpful in improving caregiver outcomes, with statistical improvement seen in a variety of caregiver domains. The type of intervention strategy used seems to influence the specificity and breadth of outcomes influenced, with some showing more results on competence and knowledge and others expanding beyond competence and knowledge to include an additional impact on the emotional well-being and quality of life of the caregiver. All three types of interventions appear to have positive impact. Care must be taken when choosing an intervention, considering what outcome is desire.

STUDY PURPOSE: To evaluate the effectiveness of olanzapine compared to other antiemetic regimens for preventative and breakthrough chemotherapy-induced nausea and vomiting (CINV). A secondary objective is to evaluate the effectiveness of 5 mg compared to 10 mg olanzapine for the prevention of CINV.
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Active antitumor treatment
APPLICATIONS: Elder care
Efficacy of Acute Phase: Olanzapine was statistically superior to non-olanzapine regimens for emesis (RR = 1.10, 95% CI [1.03, 1.17]) but not nausea. The 10 mg olanzapine was statistically superior to a non-olanzapine regimen for emesis and nausea.
Efficacy of Delayed Phase: Olanzapine was statistically superior to standard antiemetic regimens for emesis (RR = 1.31, 95% CI [1.14, 1.52]) and for nausea (RR = 1.50, 95% CI [1.15, 1.97]). The 10 mg olanzapine was statistically superior to a non-olanzapine regimen for emesis (RR = 1.31, 95% CI [1.11, 1.54]) and nausea (RR = 1.50, 95% CI [1.15, 1.97]).
Efficacy Overall: Olanzapine was statistically superior to standard anti-emetic regimens for emesis (RR = 1.41, 95% CI [1.18, 1.68]) and for nausea (RR 1.53, 95% CI [1.18, 1.97]). Olanzapine 5 mg and 10 mg were both statistically superior for emesis, and 10 mg strength was superior for nausea. No studies were available for nausea with 5 mg.
Efficacy of Breakthrough: Only emesis (not nausea) was available for analysis, and olanzapine showed superiority (RR = 2.09, 95% CI [1.63, 2.68]) to non-olanzapine regimens.
Olanzapine is effective in treating emesis at all time points and is effective in treating nausea in the delayed phase. More studies are needed to determine the most effective dosing.
Olanzapine should be used as an adjunct medication for the treatment of acute chemotherapy related vomiting, breakthrough vomiting, and delayed CINV.

STUDY PURPOSE: To use meta-analysis technique to examine the short-term and intermediate-term effects of acupuncture on menopause-related symptoms, particularly on hot flashes, in breast cancer survivors
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Multiple phases of care
Acupuncture produced small-size effects on reducing hot-flash frequency and the severity of menopause-related symptoms. This effect did not persist even one to three months on hot-flash frequency and severity.
Acupuncture and sham control procedures might offer a short-term reduction in the severity and frequency of hot flashes, but more research with larger longer studies is needed.

PHASE OF CARE: Multiple phases of care
The primary outcome was a change in a sleep parameters. The results of the meta-analysis indicated that MBIs had a medium effect size on the improvement of sleep quality, and this effect persisted up to three months after treatment. The weighted mean effect size was -0.43 (95% CI, -0.24 to -0.62), and the long-term effect size (up to three months) was -0.29 (95% CI, -0.52 to -0.06). The sensitivity analysis revealed that MBIs had a significant effect on sleep (g = -0.33, p < 0.001). The moderating effects of components of the intervention, methodologic features, subject characteristics, and the quality of the studies on the relationship between MBIs and sleep were not found (all p values > 0.05). The main interventions used in included studies in which yoga and mindfulness-based stress reduction were employed. Some studies involved the use of meditation, hypnosis, or sleep hygiene interventions. Yoga interventions yielded an effect size similar to that of other individual interventions (g = -0.40, p = 0.71).
This meta-analysis suggested that MBIs yield a medium effect size on sleep quality, and its effects are maintained for up to three months.
Although there was a comprehensive review of the literature, the selection criteria may have limited the studies included in the review, and the search strategies may have influenced the articles obtained. Only RCTs with MBIs reporting improved sleep outcomes may have been published, and studies with negative results may have been missed, causing a publication bias. Analysis was only done across all studies, which had substantially different interventions, some of which included cognitive behavioral therapy, which is shown to be effective in sleep improvement. The validity of calculating results across studies with very different interventions is questionable. Different methods of measurement were used in some studies as well. The included studies all lacked attention control.
The findings of this meta-analysis support the implementation of MBIs into multimodal approaches to managing sleep quality in patients with cancer; however, it should be recognized that this pooled analysis was done across specific interventions that were very different from each other, and there are multiple limitations that affect the strength of these conclusions.

PHASE OF CARE: Multiple phases of care
Overall, the effect size for walking on sleep disturbance was -0.52 (Hedges' g: 95%; CI -0.79, -0.25). There was significant overall heterogeneity among the studies. Multiple subgroup analyses were conducted to explore factors that may contribute to the heterogeneity. The effect size was not associated with age, gender, the duration of the intervention, or adherence rate. An analysis demonstrated no evidence of publication bias. Studies were done before, during, or after treatment for cancer, and the overall effect sizes did not differ according to the timing of the intervention. All studies used walking of moderate intensity, and most studies were done in women with breast cancer. Some studies included additional exercise interventions such as strength training, and some also included psychoeducational interventions.
Walking exercise appears to improve sleep in patients with cancer.
There was a relatively small number of studies included with high heterogeneity. Twelve studies were excluded because they did not report sufficient data to compute an effect size or they did not use a self-reported sleep outcome. These excluded studies, which have been summarized in other PEP® summaries, did not demonstrate the effectiveness of exercise. This suggests that effectiveness may be overestimated in this analysis.
This analysis provides some support for moderate intensity walking exercise to improve sleep. The findings need to be viewed with caution because of the high heterogeneity of the studies and the contrary findings that were excluded from this analysis. However, walking is a safe activity for patients, and it can be suggested to patients as an approach that may improve sleep. It also could be incorporated into multicomponent approaches to address sleep-wake disturbances.

STUDY PURPOSE: To evaluate the effects of acupuncture in reducing cancer-related pain associated with treatment types
TYPE OF STUDY: Meta-analysis and systematic review
PHASE OF CARE: Multiple phases of care
APPLICATIONS: Palliative care
Eleven trials focused on radiation-induced pain, and five focused on surgery-induced pain. The majority of trials (17) focused on general cancer-related pain. Overall analysis showed that acupuncture reduced cancer-related pain with a small effect size (-0.45, 95% CI [-0.63, -0.26]). There was high and significant heterogeneity. In the 17 trials regarding cancer-related pain, the weighted mean effect size was -0.71 (95% CI [-0.94, -0.48]), without significant heterogeneity. Among trials examining radiation-related pain, no effect was found. For surgical-related pain, mean effect size for five randomized, controlled trials was -0.4 (95% CI [-0.69, -0.1]) with high heterogeneity. For patients receiving hormonal therapy, no significant effect was seen.
Acupuncture may be helpful in reducing chronic cancer pain and pain associated with surgical procedures.
Evidence regarding efficacy of acupuncture for pain is limited; however, findings from this meta-analysis suggest that it may be helpful for chronic and acute pain in patients with cancer. Effect sizes were small.

Randomized controlled trial of live lactobacillus acidophilus plus bifidobacterium bifidum in prophylaxis of diarrhea during radiotherapy in cervical cancer patients. Radiation Oncology, 5, 31.
To determine if the combination of Lactobacillus acidophilus plus Bifidobacterium bifidum is effective in preventing diarrhea in patients with locally advanced cervical cancer receiving radiation therapy
Patients were randomized to receive either L. acidophilus plus Bifidobacterium bifidum or placebo capsules. Beginning 7 days before and continuing throughout the entire time of receiving radiotherapy, participants took 2 capsules, 2 times each day before breakfast and dinner. Patients needing antidiarrheal medication were given loperamide (2 mg).
The study was conducted in Thailand.
All patients were undergoing the active treatment phase of care.
This was a prospective, randomized, double-blind, placebo-controlled study.
The National Cancer Institute Common Toxicity Criteria, version 2, was used.
The prophylactic use of the combination of live L. acidophilus plus Bifidobacterium bifidum was shown to be effective in decreasing the severity of diarrhea.
The prophylactic use of L. acidophilus plus Bifidobacterium bifidum may decrease the severity of diarrhea, improve stool consistency, and reduce the need for antidiarrheal medication in patients with locally advanced cervical cancer undergoing pelvic radiation with concomitant weekly cisplatin. Further studies need to be done with larger samples.
