The relationship between child and caregiver sleep in acute lymphoblastic leukemia maintenance.

PURPOSE: The purposes of this study are to describe sleep quality and sleep disturbance among caregivers of children in the maintenance phase of acute lymphoblastic leukemia (ALL) and to examine the relationship between sleep quality, child sleep disturbance, and caregiver guilt and worry. METHODS: Caregivers of 68 children with ALL, ages 3 to 12 years old, completed measures of caregiver guilt and worry, caregiver sleep quality, and child's developmental history and sleep habits. Demographic and treatment correlates of poor caregiver sleep were examined, and caregiver guilt and worry was tested as a moderator between child and caregiver sleep. RESULTS: More than half of caregivers (55.9%) reported clinically significant poor sleep and less than 40% were obtaining adequate sleep durations. Caregiver sleep was significantly related to child age at diagnosis, child sleep, and caregiver guilt and worry. Caregiver guilt and worry did not moderate the relationship between child sleep and caregiver sleep. CONCLUSIONS: Poor sleep is common in caregivers of children with cancer. Further research on the timing of sleep interventions and the most effective intervention targets are needed to maximize caregiver functioning during a child's cancer treatment. Targeted interventions seeking to improve caregiver sleep should be directed towards caregivers of children diagnosed in early childhood, caregivers of children with poor sleep, and caregivers with high guilt and worry.

Symptomless Multi-Variable Apnea Prediction Index Assesses Obstructive Sleep Apnea Risk and Adverse Outcomes in Elective Surgery.

Study Objective: To validate that the symptomless Multi-Variable Apnea Prediction index (sMVAP) is associated with Obstructive Sleep Apnea (OSA) diagnosis and assess the relationship between sMVAP and adverse outcomes in patients having elective surgery. We also compare associations between Bariatric surgery, where preoperative screening for OSA risk is mandatory, and non-Bariatric surgery groups who are not screened routinely for OSA. Methods: Using data from 40 432 elective inpatient surgeries, we used logistic regression to determine the relationship between sMVAP and previous OSA, current hypertension, and postoperative complications: extended length of stay (ELOS), intensive-care-unit-stay (ICU-stay), and respiratory complications (pulmonary embolism, acute respiratory distress syndrome, and/or aspiration pneumonia). Results: Higher sMVAP was associated with increased likelihood of previous OSA, hypertension and all postoperative complications (p < .0001). The top sMVAP quintile had increased odds of postoperative complications compared to the bottom quintile. For ELOS, ICU-stay, and respiratory complications, respective odds ratios (95% CI) were: 1.83 (1.62, 2.07), 1.44 (1.32, 1.58), and 1.85 (1.37, 2.49). Compared against age-, gender- and BMI-matched patients having Bariatric surgery, sMVAP was more strongly associated with postoperative complications in non-Bariatric surgical groups, including: (1) ELOS (Orthopedics [p < .0001], Gastrointestinal [p = .024], Neurosurgery [p = .016], Spine [p = .016]); (2) ICU-stay (Orthopedics [p = .0004], Gastrointestinal [p < .0001], and Otorhinolaryngology [p = .0102]); and (3) respiratory complications (Orthopedics [p =.037] and Otorhinolaryngology [p =.011]). Conclusions: OSA risk measured by sMVAP correlates with higher risk for select postoperative complications. Associations are stronger for non-Bariatric surgeries, where preoperative screening for OSA is not routinely performed. Thus, preoperative screening may reduce OSA-related risk for adverse postoperative outcomes.
