Effects of supervised aerobic exercise on cardiorespiratory fitness and patient-reported health outcomes in colorectal cancer patients undergoing adjuvant chemotherapy-a pilot study.

PURPOSE: Colorectal cancer and its treatment are associated with debilitating side effects. Exercise may improve the physical and psychological wellbeing of cancer patients; however, evidence in colorectal cancer patients undergoing adjuvant chemotherapy is limited. This pilot study aimed to explore the effects of supervised aerobic exercise on cardiorespiratory fitness and patient-reported health outcomes in colorectal cancer patients undergoing adjuvant chemotherapy. METHODS: Patients who had undergone curative resection for colorectal cancer (stages II-III) and were scheduled to receive adjuvant chemotherapy were enrolled into this non-randomized controlled trial. Patients in the intervention group (IG) took part in a 6-month supervised aerobic exercise program, while the control group (CG) received usual care. Cardiorespiratory fitness (measured by peak oxygen consumption) was assessed at baseline and 6 months. Fatigue, quality of life, and physical activity levels were additionally assessed at 3 months. RESULTS: In total, 59 patients (33 in IG vs. 26 in CG) were enrolled into this study. Eighteen patients (9 in IG vs. 9 in CG) dropped out of the study prior to the 6-month follow-up. Significant improvements in cardiorespiratory fitness (p = .002) and selected patient-reported health outcomes, such as reduced motivation (p = .015) and mental fatigue (p = .018), were observed in the IG when compared to the CG. CONCLUSION: To our knowledge, this is the first study to investigate the effects of a supervised aerobic exercise program in colorectal cancer patients undergoing adjuvant chemotherapy. The significant and clinically meaningful improvements in CRF warrant further randomized controlled trials to confirm these findings.

Virtopsy: CT and MR imaging of a fatal head injury caused by a hatchet: A case report.

Hatchet blows to the human skull often cause fatal injuries. We present a case of homicide by hatchet blow that underwent CT, MRI, and autopsy examination. Skull fragmentation, fracture lines, and brain injuries were demonstrated prior to autopsy. Many of the hatchet-specific characteristics (flaking, crushing, shattering, and fracture lines) described in literature were observed in the post-mortem imaging of this case.
