Endoscopy within 13 h of presentation was associated with lower mortality in high-risk but not low-risk NVUGIB.

Purpose Many cancer patients experience persistent fatigue after the completion of chemotherapy. A previous single-arm study provided evidence for an effect of acupuncture in this population. We conducted a randomized controlled trial to determine whether acupuncture reduces post-chemotherapy chronic fatigue more effectively than sham acupuncture. Methods Cancer patients reporting significant fatigue persisting for at least 2 months following the completion of chemotherapy were randomized to receive once weekly true or sham acupuncture for 6 weeks. Fatigue was evaluated before and after treatment using the Brief Fatigue Inventory (BFI, the primary endpoint). Secondary endpoints included the Hospital Anxiety and Depression Scale (HADS) and Functional Assessment of Cancer Treatment-General (FACT-G) scores. Results One hundred one patients were randomized with 74 (34 true acupuncture; 40 sham control) evaluated for the primary endpoint. BFI scores fell by about one point between baseline and follow-up in both groups with no statistically significant difference between groups. HADS and FACT-G scores also improved in both groups, but there was no significant difference between groups. Patients in the sham acupuncture group crossed over to receive true acupuncture in week 7. No long-term reduction of fatigue scores was observed at the 6-month evaluation. Conclusions True acupuncture as provided in this study did not reduce post-chemotherapy chronic fatigue more than did sham acupuncture. The study is limited by the number of patients lost to follow-up. We also cannot exclude the possibility that a more intensive treatment regimen may be more effective.

Purpose. Postoperative ileus (POI) prolongs hospital stay and increases risk of postoperative complications. We conducted a randomized, sham-controlled trial to evaluate whether acupuncture reduces POI more effectively than sham acupuncture. Methods. Colon cancer patients undergoing elective colectomy were randomized to receive 30 min of true or sham acupuncture twice daily during their first 3 postoperative days. GI-3 (the later of the following two events: time that the patient first tolerated solid food, AND time that the patient first passed flatus OR a bowel movement) and GI-2 (the later of the following two events: time patient first tolerated solid food AND time patient first passed a bowel movement) were determined. Pain, nausea, vomiting, and use of pain medications were evaluated daily for the first 3 postoperative days. Results. Ninety patients were randomized. Eighty-one received the allocated intervention: 39 in the true acupuncture group and 42 in the sham acupuncture group, all evaluated for the primary endpoint. The mean time to GI-3 was 149 h [standard deviation (SD) 71 h] and 146 (SD 62 h) after surgery for the acupuncture group and the sham acupuncture group (difference between means −2 h; 95 % confidence interval −31, 26; p = 0.9). No significant differences were found between groups for secondary endpoints. Conclusions. True acupuncture as provided in this study did not reduce POI more significantly than sham acupuncture. The study was limited by a standard deviation much larger than expected, suggesting that a study with a larger sample size might be required.

The acquisition of breathing dynamics without directly recording the respiratory signals is beneficial in many clinical settings. The electrocardiography (ECG)-derived respiration (EDR) algorithm enables data acquisition in this manner. However, the EDR algorithm fails in analyzing such data for patients with atrial fibrillation (AF) because of their highly irregular heart rates. To resolve these problems, we introduce a new algorithm, referred to as SSTEDR, to extract the breathing dynamics directly from the single lead ECG signal; it is based on the EDR algorithm and the time-frequency representation technique referred to as the synchrosqueezing transform. We report a preliminary result about the relationship between the anesthetic depth and breathing dynamics. To the best of our knowledge, this is the first algorithm allowing us to extract the breathing dynamics of patients with obvious AF from the single lead ECG signal.

BACKGROUNDCurrent treatments for lymphedema after breast cancer treatment are expensive and require ongoing intervention. Clinical experience and our preliminary published results suggest that acupuncture is safe and potentially useful. This study evaluates the safety and potential efficacy of acupuncture on upper-limb circumference in women with lymphedema.METHODSWomen with a clinical diagnosis of breast cancer−related lymphedema (BCRL) for 0.5-5 years and with affected arm circumference ≥2 cm larger than unaffected arm received acupuncture treatment twice weekly for 4 weeks. Affected and unaffected arm circumferences were measured before and after each acupuncture treatment. Response, defined as ≥30% reduction in circumference difference between affected/unaffected arms, was assessed. Monthly follow-up calls for 6 months thereafter were made to document any complications and self-reported lymphedema status.RESULTSAmong 37 enrolled patients, 33 were evaluated; 4 discontinued due to time constraints. Mean reduction in arm circumference difference was 0.90 cm (95% CI, 0.72-1.07; P < .0005). Eleven patients (33%) exhibited a reduction of ≥30% after acupuncture treatment. Seventy-six percent of patients received all treatments; 21% missed 1 treatment, and another patient missed 2 treatments. During the treatment period, 14 of the 33 patients reported minor complaints, including mild local bruising or pain/tingling. There were no serious adverse events and no infections or severe exacerbations after 255 treatment sessions and 6 months of follow-up interviews.CONCLUSIONSAcupuncture for BCRL appears safe and may reduce arm circumference. Although these results await confirmation in a randomized trial, acupuncture can be considered for women with no other options for sustained arm circumference reduction.
