Depression, Anxiety, Stress and Distress Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Results of a Prospective Cohort Study.

The aim of this study was to describe the levels of depression, anxiety, stress, and distress in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The 21-item Depression, Anxiety and Stress Scale (DASS-21) and Distress Thermometer were administered preoperatively, postoperatively day 10, and at hospital discharge to 169 patients with peritoneal carcinomatosis undergoing CRS and HIPEC. The mean preoperative values for DASS-21 subscale scores were 4.7 (depression), 4.2 (anxiety), and 8.4 (stress), and the mean preoperative Distress Thermometer rating was 4.0. No significant changes in levels of depression, stress, or distress were noted thereafter. The DASS-21 anxiety subscale score significantly increased at hospital discharge (p = .005). Higher levels of preoperative psychological depression, anxiety, stress and distress were associated with worse mental component scores. Higher preoperative depression levels were associated with the provision of more clinical psychologist occasions of service, and higher preoperative distress levels were associated with younger age. Preoperative psychological measures are important for ensuring CRS and HIPEC patients that require additional support are identified and provided with ongoing psychological interventions.

Comparative inactivation of adenovirus serotypes by UV light disinfection.

The results of this study confirm that adenoviruses are the most resistant enteric viruses to inactivation by UV light and that adenovirus 40 appears to be the most resistant. The effect of freeze-thawing and storage in water may affect the sensitivity of some adenoviruses to inactivation by UV light.
