Abstract
OBJECTIVE To determine if interindividual genetic variation in single-nucleotide polymorphisms (SNPs) related to age at natural menopause is associated with risk of ovarian failure in breast cancer survivors. METHODS A prospective cohort of 169 premenopausal breast cancer survivors recruited at diagnosis with stages 0 to III disease were followed longitudinally for menstrual pattern via self-reported daily menstrual diaries. Participants were genotyped for 13 SNPs previously found to be associated with age at natural menopause: EXO1, TLK1, HELQ, UIMC1, PRIM1, POLG, TMEM224, BRSK1, and MCM8. A risk variable summed the total number of risk alleles in each participant. The association between individual genotypes, and also the risk variable, and time to ovarian failure (>12 months of amenorrhea) was tested using time-to-event methods. RESULTS Median age at enrollment was 40.5 years (range 20.6-46.1). The majority of participants were white (69%) and underwent chemotherapy (76%). Thirty-eight participants (22%) experienced ovarian failure. None of the candidate SNPs or the summary risk variable was significantly associated with time to ovarian failure. Sensitivity analysis restricted to whites or only to participants receiving chemotherapy yielded similar findings. Older age, chemotherapy exposure, and lower body mass index were related to shorter time to ovarian failure. CONCLUSIONS Thirteen previously identified genetic variants associated with time to natural menopause were not related to timing of ovarian failure in breast cancer survivors.

Abstract
e21706 Background: Up to 20% of breast cancer survivors develop breast cancer related lymphedema (BCRL), and current therapies are limited. In a previous single armed study, acupuncture appeared to reduce BCRL. In this study, we compared our specific protocol of acupuncture (AC) to usual care wait list control (WL). Methods: Women with moderate persistent BCRL were randomized to AC or WL. The AC protocol included twice-weekly manual acupuncture over 6 weeks. The primary endpoint was change in circumference difference between affected/unaffected arms. Responders were defined as having > 30% improvement in arm circumference difference between arms. We also evaluated the change in difference between affected/unaffected arm bioimpedance. We used analysis of covariance for circumference and bioimpedance measurements and Fisher’s exact test for proportion of responders. Results: Among 82 patients, 73 (89%) were evaluable for the primary endpoint (36 in AC and 37 in WL). The median age in AC was 65 (IQR 54, 71) and 58 (IQR 49, 70) in WL. Most patients in both arms had undergone mastectomy (74%) and axillary lymph node dissection (96%), and had a history of prior lymphedema treatment (96%). Median duration of lymphedema was 2.2 years in AC (IQR 1.3, 3.0) and 2.5 years in WL (IQR 1.4, 3.4). We found no evidence of a difference in either arm circumference difference improvement (β -0.38cm, 95% CI -0.89, 0.12, p = 0.14) or bioimpedance difference improvement (β -1.06, 95% CI -7.85, 5.72, p = 0.8) between AC and WL at Week 6. There was also no difference in proportion of responders: 17% AC vs. 11% WL (6% difference, 95% CI -10%, 22%, p = 0.5). No severe adverse events (AE) were reported. Grade 1 treatment-related AEs such as bruising (58%), hematoma (2%), and pain (2%) were reported in patients receiving AC. Among the 837 acupuncture treatments provided, one possibly related grade 2 skin infection was reported. Conclusions: Although it appears to be safe and well tolerated, our acupuncture protocol did not offer additional clinically meaningful reductions in BCRL compared with usual care among patients who had received lymphedema treatment. This regimen should not be recommended for breast cancer survivors with persistent BCRL. Clinical trial information: NCT01706081.

Abstract
8021 Background: Hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for a number of hematologic malignancies, but is associated with a high symptom burden for patients. We conducted a randomized sham-controlled trial to evaluate the preliminary efficacy and safety of acupuncture as an integrative treatment for managing common symptoms during HCT. Methods: Adult patients with multiple myeloma undergoing high dose melphalan followed by autologous peripheral blood HCT were randomized to receive either true or sham acupuncture once daily for five days starting on the day after chemotherapy. Symptom burden was assessed with the MD Anderson Symptom Inventory (MDASI) at baseline, during transplantation, and at 15 and 30 days after transplantation. Results: Among 60 participants, symptoms that are significantly reduced by true acupuncture more than sham acupuncture at 15 days include the following: nausea, lack of appetite, and drowsiness (p = 0.042, 0.025, and 0.010, respectively). Patients receiving sham acupuncture were more likely to increase use of pain medication post-transplantation (odds ratio 5.31, p = 0.017). Acupuncture was well tolerated with few attributable adverse events. Conclusions: True acupuncture may prevent escalation of symptoms including nausea, lack of appetite, and drowsiness experienced by patients undergoing autologous HCT, and to reduce the use of pain medications. These findings need to be confirmed in a future definitive study. Clinical trial information: NCT01811862.

Abstract
Insulin-like peptides (ILPs) act through a conserved insulin signaling pathway and play crucial roles in insect metabolism, growth, reproduction, and aging. Application of bovine insulin is able to increase vitellogenin (Vg) mRNA and protein levels in female insects. Here, we first show that injection of bovine insulin into previtellogenic Chrysopa septempunctata female adults promoted ovarian growth, increased Vg protein abundance, elevated reproductive performance, and enhanced protease activity. These data suggested that ILPs play crucial roles in reproductive regulation of the green lacewing, C. septempunctata.

Abstract
Abstract
Background:Aromatase inhibitors (AIs) are associated with reduced risk of breast cancer recurrence, yet many women discontinue their treatment prematurely, often due to arthralgia. Empirically, breast cancer survivors who experience AI-associated arthralgia often report that they have aged quickly over a short period of time. Objective: We aimed to determine whether survivors with a heightened sense of aging due to arthralgia were more likely to non-adhere to their AI regimen. Methods: We conducted a prospective cohort study in an urban academic cancer center among post-menopausal women with hormone receptor positive breast cancer who were within the first two years of their aromatase inhibitor therapy. Perceptions of aging due to arthralgia were measured by the previously validated Penn Arthralgia Aging Scale. Non-adherence was defined as interrupting treatment or discontinuing the AI before the prescribed treatment length was over. Trained raters abstracted adherence data from medical charts. We performed Cox proportional hazards regression to evaluate the relationship between perceptions of aging due to arthralgia and time to non-adherence while adjusting for potential confounders. Results: Among 509 participants, most were White (81.2%) and had at least some college education (77.9%). The majority had been prescribed anastrozole (88.0%), followed by letrozole (9.0%), and exemestane (3.0%). During the follow up period, 144 (28.3%) did not adhere to the AIs as originally prescribed. In univariate analysis, women with a heightened sense of aging due to arthralgia were at more than twice the risk of non-adherence compared to women with low levels of aging perceptions (Hazard Ratio [HR], 2.20; 95% CI, 1.50 – 3.21; p < 0.001). After adjusting for arthralgia pain severity, depression, and AI type, aging perceptions remained a statistically significant predictor of adherence (HR, 1.71; 95% CI, 1.10-2.67; p = 0.02). Depression status also uniquely predicted non-adherence risk (HR, 1.63; 95% CI, 1.03 – 2.59; p = 0.04). Arthralgia pain severity, which predicted adherence in univariate analysis, was not a significant predictor in the final model (HR, 1.21; 95% CI, 0.84 – 1.75; p = .30). Conclusions: Breast cancer survivors on AIs who have a heightened sense of aging due to arthralgia are at greater risk of non-adhering to their AI regimen. Interventions are needed to help survivors reduce arthralgia and develop adaptive appraisals of their AI experience to achieve optimal adherence.

Abstract
196 Background: Cancer survivors often experience substantial psychological distress, such as anxiety and depression, due to cancer diagnosis and treatment. As psychological support is still not a standard part of survivorship care in China, little is known about Chinese oncologists’ attitudes towards referring cancer survivors to this service. Methods: We conducted a cross-sectional survey among oncologists who were attending the 18th annual meeting of Chinese Society of Clinical Oncology (CSCO, September 16th - 20th 2015) in Xiamen, China. Participants voluntarily completed a questionnaire measuring their demographics and occupational information. The outcome variable was willingness to refer cancer survivors to psychological support. We used a multivariate logistic regression model to evaluate the factors associated with such willingness. Results: Among 351 responders, 53% were male, with a mean age of 38±9 years. Half of the oncologists were senior attendings, 34% were junior attendings, and 17% were residents. More than half of the physicians (58%) had an additional Masters or PhD degree. The majority of oncologists (263, 79%) were willing to refer their patients to psychological support as part of survivorship care. Physicians over 40 years old were more likely to recommend psychological support than their younger colleagues (85% versus 76%, p = 0.048). In multi-variable logistic regression model, controlled by gender and education level, physicians > 40 years were associated with more willingness to refer their patients to psychological support than physicians ≤ 40 years (odds ratio [OR] 2.9, 95% confidential interval [C.I.]1.4-6.1, p= 0.01); compared to residents, junior attendings were more likely to recommend psychological support (OR 2.8, 95% C.I. 1.1-7.1, p= 0.03). Conclusions: The majority of Chinese oncologists were willing to refer cancer survivors for psychological support; age and position appeared to impact such willingness. By further educating young Chinese oncologists about the importance of psychological care during survivorship, we can help develop a health care delivery system that better meets Chinese cancer survivors’ psychosocial needs.

Abstract
162 Background: Cancer patients experience a variety of symptoms (e.g., pain, fatigue) that can impact their ability to maintain physical activity (PA) levels. The objectives of this study were to examine factors associated with decreased levels of PA following cancer diagnosis and to identify barriers to PA. Methods: We recruited cancer patients from one urban academic medical center and 11 affiliated community hospitals to participate in a cross-sectional study. We conducted chi-square tests and multivariate logistic regression models to examine patient demographics, clinical characteristics and self-reported barriers associated with decrease in PA levels since cancer diagnosis. Results: Among 662 participants, mean age (SD) was 59.9 (11.6) years. The majority were female (65%), White (81%), and overweight/obese (65%). Common cancer types were breast (32%), lung/thoracic (15%), and hematological (15%), 53% had non-metastatic disease, and 53% were > 12 months post-cancer diagnosis. The majority received chemotherapy (88%), radiation (53%), and/or surgery (53%). Since their cancer diagnosis, 499 (75%) participants reported decreasing their PA levels, 16% maintained, and 4% increased their PA levels. In multivariate analyses, decreased PA levels were significantly associated with receiving chemotherapy [Adjusted Odds Ratio (AOR) 3.54, 95% CI 2.06-6.06] and having metastatic disease (AOR 1.64, 95% CI 1.07-2.52). For barriers to PA, the most common were fatigue (78%), pain (71%), difficulty getting motivated (68%) and difficulty remaining disciplined (65%). In bivariate analyses, the presence of symptoms (i.e., pain, nausea, fatigue, treatment side effects, or surgical complications), difficulty getting motivated, difficulty remaining disciplined, and sadness were significantly associated (p < 0.05) with decreasing PA levels. Conclusions: The majority of cancer patients, especially those who received chemotherapy and those with advanced disease, decreased their PA levels since cancer diagnosis. In addition, physical and psychological barriers exist that influence PA levels. Interventions targeting these barriers are needed to promote maintenance of PA levels throughout the cancer continuum.

Abstract
OBJECTIVE This article reports on the development, implementation, and evaluation of an integrative clinical oncology massage program for patients undergoing chemotherapy for breast cancer in a large academic medical center. MATERIALS AND METHODS We describe the development and implementation of an oncology massage program embedded into chemoinfusion suites. We used deidentified program evaluation data to identify specific reasons individuals refuse massage and to evaluate the immediate impact of massage treatments on patient-reported outcomes using a modified version of the Distress Thermometer delivered via iPad. We analyzed premassage and postmassage data from the Distress Thermometer using paired t test and derived qualitative data from participants who provided written feedback on their massage experiences. RESULTS Of the 1,090 massages offered, 692 (63%) were accepted. We observed a significant decrease in self-reported anxiety (from 3.9 to 1.7), nausea (from 2.5 to 1.2), pain (from 3.3 to 1.9), and fatigue (from 4.8 to 3.0) premassage and postmassage, respectively (all P < .001). We found that 642 survey participants (93%) were satisfied with their massage, and 649 (94%) would recommend it to another patient undergoing treatment. Spontaneous patient responses overwhelmingly endorsed the massage as relaxing. No adverse events were reported. Among the 398 patients (36%) who declined a massage, top reasons were time concerns and lack of interest. CONCLUSION A clinical oncology massage program can be safely and effectively integrated into chemoinfusion units to provide symptom control for patients with breast cancer. This integrative approach overcomes patient-level barriers of cost, time, and travel, and addresses the institutional-level barrier of space.

Abstract
BACKGROUND Although poor adherence to hormonal therapies such as aromatase inhibitors (AIs) is widely documented, to the authors' knowledge less is known regarding whether health beliefs predict treatment nonadherence. The objective of the current study was to evaluate the relationship between health beliefs (perceived susceptibility to breast cancer, perceived benefits of AI treatment, and perceived barriers to AI treatment) and adherence to AIs. METHODS Postmenopausal women with early-stage, estrogen receptor-positive breast cancer who were currently receiving treatment with an AI completed the 3-factor Health Beliefs and Medication Adherence in Breast Cancer scale and questionnaires concerning their demographics and symptoms. Adherence data (treatment gaps and premature discontinuation) were abstracted from participants' medical charts. Logistic regression analyses were conducted to evaluate the relationship between health beliefs and adherence. RESULTS Among 437 participants, 93 (21.3%) were nonadherent. Those who perceived greater barriers to their AI treatment were more likely to demonstrate AI nonadherence behaviors by the end of their treatment period compared with those who reported fewer barriers to AI therapy (adjusted odds ratio, 1.71; 95% confidence interval, 1.03-2.86 [P = .04]). In contrast, perceived susceptibility to cancer recurrence and perceived benefits of AIs did not appear to predict AI adherence. Minority individuals were found to have lower perceived susceptibility to breast cancer recurrence and higher perceived barriers to AI treatment (P<.05 for both). CONCLUSIONS Greater perceived barriers appeared to predict nonadherence to AIs. Interventions addressing women's negative beliefs regarding the challenges of AI treatment are needed to help optimize adherence in survivors of breast cancer.

Abstract
OBJECTIVE Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. METHODS Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. RESULTS Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). CONCLUSIONS Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. REGISTRATION Trial Number NCT01072344 at ClinicalTrials.gov.

Abstract
BACKGROUND Conventional drug treatments for Generalized Anxiety Disorder (GAD) are often accompanied by substantial side effects, dependence, and/or withdrawal syndrome. A prior controlled study of oral chamomile (Matricaria chamomilla L.) extract showed significant efficacy versus placebo, and suggested that chamomile may have anxiolytic activity for individuals with GAD. HYPOTHESIS We hypothesized that treatment with chamomile extract would result in a significant reduction in GAD severity ratings, and would be associated with a favorable adverse event and tolerability profile. STUDY DESIGN We report on the open-label phase of a two-phase randomized controlled trial of chamomile versus placebo for relapse-prevention of recurrent GAD. METHODS Subjects with moderate to severe GAD received open-label treatment with pharmaceutical-grade chamomile extract 1500mg/day for up to 8 weeks. Primary outcomes were the frequency of clinical response and change in GAD-7 symptom scores by week 8. Secondary outcomes included the change over time on the Hamilton Rating Scale for Anxiety, the Beck Anxiety Inventory, and the Psychological General Well Being Index. Frequency of treatment-emergent adverse events and premature treatment discontinuation were also examined. RESULTS Of 179 subjects, 58.1% (95% CI: 50.9% to 65.5%) met criteria for response, while 15.6% prematurely discontinued treatment. Significant improvement over time was also observed on the GAD-7 rating (β=-8.4 [95% CI=-9.1 to -7.7]). A similar proportion of subjects demonstrated statistically significant and clinically meaningful reductions in secondary outcome ratings of anxiety and well-being. Adverse events occurred in 11.7% of subjects, although no serious adverse events occurred. CONCLUSION Chamomile extract produced a clinically meaningful reduction in GAD symptoms over 8 weeks, with a response rate comparable to those observed during conventional anxiolytic drug therapy and a favorable adverse event profile. Future comparative effectiveness trials between chamomile and conventional drugs may help determine the optimal risk/benefit of these therapies for patients suffering from GAD.

Abstract
BACKGROUND Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders treated in primary care, yet current therapies have limited efficacy and substantial side effects. PURPOSE To evaluate long-term chamomile (Matricaria chamomilla L.) use for prevention of GAD symptom relapse. METHODS Outpatients from primary care practices and local communities with a primary diagnosis of moderate-to-severe GAD were enrolled for this two-phase study at a large US academic medical center. During Phase 1, eligible participants received 12 weeks of open-label therapy with chamomile pharmaceutical grade extract 1500mg (500mg capsule 3 times daily). During Phase 2, treatment responders were randomized to either 26 weeks of continuation chamomile therapy or placebo in a double-blinded, placebo-substitution design. The primary outcome was time to relapse during continuation therapy, analyzed using Cox proportional hazards. Secondary outcomes included the proportion who relapsed, treatment-emergent adverse events, and vital sign changes. This study is registered at ClinicalTrials.gov, identifier NCT01072344. RESULTS Between March 1, 2010, and June 30, 2015, we enrolled 179 participants. Of those, 93 (51.9%) were responders and agreed to continue in the double-blind randomized controlled trial. A numerically greater number of placebo-switched (n=12/47; 25.5%) versus chamomile-continuation (n = 7/46; 15.2%) participants relapsed during follow-up. Mean time to relapse was 11.4 ± 8.4 weeks for chamomile and 6.3 ± 3.9 weeks for placebo. Hazard of relapse was non-significantly lower for chamomile (hazard ratio, 0.52; 95% CI, 0.20-1.33; P = 0.16). During follow-up, chamomile participants maintained significantly lower GAD symptoms than placebo (P = 0.0032), with significant reductions in body weight (P = 0.046) and mean arterial blood pressure (P = 0.0063). Both treatments had similar low adverse event rates. CONCLUSIONS Long-term chamomile was safe and significantly reduced moderate-to-severe GAD symptoms, but did not significantly reduce rate of relapse. Our limited sample size and lower than expected rate of placebo group relapse likely contributed to the non-significant primary outcome finding. Possible chamomile superiority over placebo requires further examination in large-scale studies.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is a common toxicity associated with chemotherapy, but researchers rarely study its risk factors, fall risk, and prevalence in long-term breast cancer survivors. We aimed to determine CIPN prevalence, risk factors, and association with psychological distress and falls among long-term breast cancer survivors. We conducted Cross-sectional analyses among postmenopausal women with a history of stage I-III breast cancer who received taxane-based chemotherapy. Participants reported neuropathic symptoms of tingling/numbness in hands and/or feet on a 0-10 numerical rating scale. We conducted multivariate logistic regression analyses to evaluate risk factors associated with the presence of CIPN and the relationship between CIPN and anxiety, depression, insomnia, and patient-reported falls. Among 296 participants, 173 (58.4 %) reported CIPN symptoms, 91 (30.7 %) rated their symptoms as mild, and 82 (27.7 %) rated them moderate to severe. Compared with women of normal weight, being obese was associated with increased risk of CIPN (adjusted OR 1.94, 95 % CI: 1.03-3.65). Patients with CIPN reported greater insomnia severity, anxiety, and depression than those without (all p < 0.05). Severity of CIPN was associated with higher rates of falls, with 23.8, 31.9, and 41.5 % in the "no CIPN," "mild," and "moderate-to-severe" groups, respectively, experiencing falls (p = 0.028). The majority of long-term breast cancer survivors who received taxane-based chemotherapy reported CIPN symptoms; obesity was a significant risk factor. Those with CIPN also reported increased psychological distress and falls. Interventions need to target CIPN and comorbid psychological symptoms, and incorporate fall prevention strategies for aging breast cancer survivors.

Abstract
BACKGROUND Although poor adherence to hormonal therapies such as aromatase inhibitors (AIs) is widely documented, to the authors' knowledge less is known regarding whether health beliefs predict treatment nonadherence. The objective of the current study was to evaluate the relationship between health beliefs (perceived susceptibility to breast cancer, perceived benefits of AI treatment, and perceived barriers to AI treatment) and adherence to AIs. METHODS Postmenopausal women with early-stage, estrogen receptor-positive breast cancer who were currently receiving treatment with an AI completed the 3-factor Health Beliefs and Medication Adherence in Breast Cancer scale and questionnaires concerning their demographics and symptoms. Adherence data (treatment gaps and premature discontinuation) were abstracted from participants' medical charts. Logistic regression analyses were conducted to evaluate the relationship between health beliefs and adherence. RESULTS Among 437 participants, 93 (21.3%) were nonadherent. Those who perceived greater barriers to their AI treatment were more likely to demonstrate AI nonadherence behaviors by the end of their treatment period compared with those who reported fewer barriers to AI therapy (adjusted odds ratio, 1.71; 95% confidence interval, 1.03-2.86 [P = .04]). In contrast, perceived susceptibility to cancer recurrence and perceived benefits of AIs did not appear to predict AI adherence. Minority individuals were found to have lower perceived susceptibility to breast cancer recurrence and higher perceived barriers to AI treatment (P<.05 for both). CONCLUSIONS Greater perceived barriers appeared to predict nonadherence to AIs. Interventions addressing women's negative beliefs regarding the challenges of AI treatment are needed to help optimize adherence in survivors of breast cancer.

Abstract
OBJECTIVES Diagnostic imaging may be a major source of cancer-related distress, a condition known as "scanxiety". Scant scholarly work has been performed to evaluate scan-associated distress in cancer. We sought to characterize risk factors for scan-associated distress among patients with Non-Small Cell Lung Cancer (NSCLC), and to evaluate the impact of scan-associated distress on quality of life. MATERIALS AND METHODS We conducted a cross-sectional survey study of patients with recurrent/metastatic NSCLC treated at an academic medical center. Clinical and demographic variables were obtained through chart abstraction and patient self-report. We used a modified version of the Impact of Event Scale 6 (IES-6) to specifically assess distress associated with scans, and quality of life was measured using the Functional Assessment of Cancer Therapy - Lung (FACT-L). RESULTS Among 103 participants (survey response rate 76.3%), median age was 67, 61.2% were women, and 82.5% were white. At the study visit, 72.8% of subjects discussed a recent scan, and 83% reported some scan-associated distress. Scan-associated distress was not associated with whether the patient had a recent scan, progressive disease or time from diagnosis. Scan-associated distress was associated with impaired quality of life (p=0.004); each unit increase in IES-6 corresponded to an approximately one-unit decrease in FACT-L score. CONCLUSION Scan-associated distress is a common problem among patients with NSCLC, and is associated with impaired quality of life. Scan-associated distress severity was not associated with time since diagnosis or whether a recent scan was discussed at the study visit, which implies scan-associated distress may be a persistent problem.

Abstract
BACKGROUND Fatigue is the most common symptom negatively affecting the quality of life of patients with cancer. The objective of the current study was to evaluate the preliminary efficacy and safety of 10.6‐μm infrared laser moxibustion for cancer‐related fatigue (CRF). METHODS The authors conducted a randomized, placebo‐controlled trial among 78 patients with cancer who were diagnosed with CRF. The group treated with infrared laser moxibustion received 10.6 μm of infrared laser moxibustion on the ST36 (bilateral), CV4, and CV6 acupoints. Each participant received a 20‐minute treatment session 3 times per week for 4 weeks. The sham group received the same treatment duration on the same acupoints, but without infrared laser output. The outcome was change in fatigue as measured by the Chinese version of the Brief Fatigue Inventory between groups at week 4 with additional evaluation at week 8 for durability of treatment effects. A mixed effects model was used to evaluate the difference in treatment effect over time. RESULTS Among those randomized, 61 patients (78%) completed the entire study. At the end of the intervention, the individuals in the group treated with the laser were found to have significantly less fatigue than those in the sham group (3.01 vs 4.40; P = .002). The improvement in fatigue persisted to week 8, favoring the group treated with laser moxibustion (3.03 vs 4.26; P = .006). Laser moxibustion was safe, with 3 cases of mild local erythema that resolved without medical intervention reported. CONCLUSIONS Infrared laser moxibustion appeared to be safe and efficacious for improving CRF in a Chinese patient population. Larger studies in more racial/ethnically diverse populations are needed to confirm the benefit of this technique for fatigue in patients with cancer. Cancer 2016;122:3667‐72. © 2016 The Authors.

Abstract
INTRODUCTION Treatment-related joint pain affects almost half of all women with breast cancer using aromatase inhibitors and is a major reason for terminating treatment. Although acupuncture is becoming an increasingly popular, evidence-based option for treating pain, little is known about the potential influence of psychological factors on acupuncture use. OBJECTIVE We aimed to evaluate the association between pain catastrophising and use of acupuncture in breast cancer survivors experiencing arthralgia. METHODS We conducted a cross-sectional survey of arthralgic breast cancer patients. Patients were asked if they had used acupuncture since their cancer diagnosis. The Pain Catastrophising Scale (PCS) was used to measure negative coping styles related to the experience of pain. We performed multiple logistic regression analysis to evaluate the relationship between pain catastrophising and acupuncture use, adjusting for covariates. RESULTS Of the 424 participants, 69 (16%) reported use of acupuncture since their breast cancer diagnosis. In multivariate analyses, compared to those in the lowest PCS score tertile, patients with the highest PCS scores were more likely to have used acupuncture (p=0.03). In particular, patients with high levels of rumination (p=0.005) and magnification (p=0.008) were more likely to have used acupuncture. Helplessness was not associated with acupuncture use (p=0.23). CONCLUSIONS High levels of pain catastrophising, and specifically the processes of rumination and magnification, were associated with greater acupuncture use. We believe this could have important implications for understanding which population is more likely to seek acupuncture treatment and how this alternative therapy could be better targeted to these patients.

Abstract
Purpose. Dyspnea is a common and distressing symptom for patients with lung cancer (LC) because of disease burden, therapy toxicity, and comorbid illnesses. Acupuncture is a centuries-old therapy with biological plausibility for relief of dyspnea in this setting. This pilot study aimed to evaluate the feasibility and preliminary effectiveness of acupuncture for dyspnea among patients with LC. Methods. Eligible patients had a diagnosis of LC and clinically significant dyspnea without a clear organic cause. The treatment consisted of 10 weekly acupuncture sessions, with a follow-up visit 4 weeks after therapy. The primary outcome was dyspnea severity as measured using a validated Numerical Rating Scale (NRS) of 0 to 10 (10 being “most severe shortness of breath imaginable”). Results. We enrolled 12 patients in the study. The median age was 64.5 years; 66.7% of the patients were female, and 66.7% were Caucasians. Among those enrolled, 10 (83.3%) were able to complete all 10 acupuncture sessions. Acupuncture was well tolerated; adverse events were mild and self-limited. Mean (SD) dyspnea scores on the NRS improved from 6.3 (1.7) at baseline to 3.6 (1.9; P = .003) at the end of treatment and 3.2 (2.3; P = .008) at follow-up. Fatigue and quality of life also improved significantly with acupuncture (P < .05). Conclusion. Among patients with LC, acupuncture was well tolerated and exhibited promising preliminary beneficial effects in the treatment of dyspnea, fatigue, and quality of life. Performing a trial in this population appears feasible.

AIMS To compare the safety and effectiveness of antidepressantv.mood stabiliser monotherapy for bipolar type II major depressive episodes. METHOD Randomised, double-blind, parallel-group, 12-week comparison of venlafaxine (n= 65)v.lithium (n= 64) monotherapy in adult out-patients (trial registration numberNCT00602537). RESULTS Primary outcome - venlafaxine produced a greater response rate (67.7%)v lithium (34.4%,P<0.001). Secondary outcomes - venlafaxine produced a greater remission rate (58.5%v 28.1%,P<0.001); greater decline in depression symptom scores over time (β = -5.32, s.e. = 1.16, χ(2)= 21.19,P<0.001); greater reduction in global severity scores over time (β = -1.05, s.e. = 0.22, w(2)= 22.33,P<0.001); and greater improvement in global change scores (β = -1.31, s.e. = 0.32, χ(2)= 16.95,P<0.001) relative to lithium. No statistically significant or clinically meaningful differences in hypomanic symptoms were observed between treatments. CONCLUSIONS These findings suggest that short-term venlafaxine monotherapy may provide effective antidepressant treatment for bipolar II depression without a statistically significant increase in hypomanic symptoms relative to lithium.

Abstract
Abstract
Background: Post-menopausal breast cancer survivors are often prescribed aromatase inhibitors (AIs) to decrease the chance of cancer recurrence. Despite their efficacy, many survivors do not fully adhere to their AI regimen. To improve adherence rates, it is important to understand which patient factors are associated with adherence. Current research has mostly focused on demographic, cancer, and symptom variables, most of which cannot be modified. One relevant factor that may be modifiable is health beliefs, which include perceived susceptibility of cancer recurrence, perceived benefits of treatment, and perceived barriers to treatment. Among breast cancer patients, each of these has been found to be associated with adherence behaviors, such as mammography and tamoxifen adherence. In this study, we explored whether health beliefs also play a role in adherence to AIs. Objective: The purpose of this longitudinal study was to determine whether patients with lower perceived susceptibility to cancer recurrence, higher perceived barriers to taking AIs, and lower perceived benefits of AIs were more likely to non-adhere to their AI regimen. Method: Four hundred and thirty-seven breast cancer survivors who were currently on an AI completed a survey that included the Health Beliefs and Medication Adherence in Breast Cancer (HBMABC) scales (a measure adapted from the Champion Health Belief Model Scales (CHBMS) for Mammography Screening), as well as questions about their demographics and symptoms. Exploratory and confirmatory factor analysis of the HBMABC yielded a 3-factor solution: perceived susceptibility, perceived benefits, and perceived barriers. Adherence data, including drug holidays (taking breaks from AI treatment) and premature discontinuation (stopping AI treatment early), were collected from physicians' notes in patients' medical charts dating from the day they completed the survey through the end-date of their prescribed AI treatment. Bivariate analyses were conducted to determine variables that were predictive of non-adherence. Variables found to be associated with non-adherence were entered into multiple logistic regression analyses. Results: Eighty-five patients (20.6%) exhibited some form of non-adherence (premature discontinuation, drug holiday, or both). Joint pain severity and the number of years a patient was on an AI at the time of the survey were both associated with non-adherence. After adjusting for these covariates, perceived barriers to AI treatment was significantly associated with non-adherence (OR 1.76, 95% CI: 1.03 – 3.00, p = 0.04). No relationship was found between perceived susceptibility or perceived benefits, and AI adherence. Conclusions: Breast cancer patients on AIs who perceive greater barriers to AI treatment are more likely to non-adhere to their AI regimen. This finding suggests that clinicians can intervene to help modify patients' negative beliefs and ultimately help improve patients' adherence levels.
