Longitudinal Changes in Sleep: Associations with Shifts in Circulating Cytokines and Emotional Distress in a Cancer Survivor Population.

BACKGROUND: Sleep disturbances are associated with numerous mood disorders. Similarly, anxiety and depression are associated with modulation of the psychoneuroimmune (PNI) axis. This study hypothesized that changes in both monitored and self-reported measures of sleep would relate to changes in circulating cytokine levels in an emotionally distressed population of cervical cancer survivors. METHODS: Biospecimens, patient-reported outcome (PRO) measures, and actigraphy were collected from cervical cancer survivors enrolled in a biobehavioral clinical trial. Longitudinal changes over a 4-month period were examined. Sleep time measured by actigraphy and PRO were analyzed for correlative changes with emotional distress and serum cytokines (n = 71). RESULTS: Longitudinal change in the actigraph measure of sleep time was inversely associated with changes in depression and anxiety (test for linear trend, p = 0.02 and p = 0.05 respectively), as well as acute-phase response/pro-inflammatory cytokines (test for linear trend, p = 0.003, interleukin (IL)-2; 0.022, IL-1ß; 0.0002, IL-6; and 0.049, tumor necrosis factor α). Conversely, changes in self-reported sleep problems were related to an increase in depression and anxiety (p = 0.001 and p = 0.01 respectively), the T helper 2 (Th2) cytokine IL-5 (p = 0.027), and the counter-regulatory cytokine IL-10 (0.016). CONCLUSION: This study showed that an increase in sleep time or decrease in sleep problems corresponded with a reduction in self-reported emotional distress and attenuation of pro-inflammatory, Th2, and counter-regulatory cytokines. Our results support sleep measurement as a meaningful biobehavioral variable in cancer survivorship. This study also indicates that sleep investigators should be aware that choice of methodology might influence concordance with different classes of immune parameters.

The Lived Experience of Child Marriage in the United States.

Despite international and domestic calls to end child marriage, 48 U.S. states permit the marriage of minors younger than age 18 as of August 2018. In developing nations, child marriage is associated with a wide range of adverse economic, health, and mental health outcomes, yet little research has been done to understand its effects on developed nations such as the United States. This study is the first to interview adults who were married as children in the United States, to investigate the reasons why the marriages occurred, and qualitatively understand the experiences of married American children. 21 participants (20 females and 1 male) self-selected into this study to complete an online questionnaire and be interviewed by phone. Participants were married between ages 13 and 17. Most participants (n = 18) reported physical, sexual, financial, or emotional abuse during their marriage as well as unwanted and/or unplanned pregnancies. This study shows some important social justice issues related to consent and the qualitative differences inherent in deciding to marry during childhood. Notably, this study did not find that pregnancy was the reason most participants married as minors, as some policy debates across the U.S. report.

Relationship between social support, quality of life, and Th2 cytokines in a biobehavioral cancer survivorship trial.

OBJECTIVE: Benefits of social support (SS) during cancer survivorship are complex. This study examines change in SS over time in cervical cancer (CXCA) survivors who have completed definitive treatment and how changing SS impacts quality of life (QOL) and T-helper type 2 (Th2) cytokines. METHODS: We conducted a randomized trial in 204 CXCA survivors to test if psychosocial telephone counseling (PTC) could improve QOL compared to usual care (UC). Although PTC did not target SS, data were collected at baseline, 4 and 9 months post-enrollment using the Medical Outcomes Survey Social Support scale. Biospecimens were collected to investigate associations with patient-reported outcomes. Data were analyzed using multivariate linear models and stepwise regression. RESULTS: Participants' mean age was 43. PTC participants experienced increasing SS compared to UC at 4 months (PTC-UC = 5.1; p = 0.055) and 9 months (PTC-UC = 6.0; p = 0.046). Higher baseline SS and increasing SS were independently associated with improved QOL at 4 and 9 months after adjusting for patient characteristics (p < 0.05). Differences between study arms were not statistically significant. Improvements in QOL at 4 months were observed with increases in emotional/informational and tangible SS. Increasing SS predicted significant longitudinal decreases in IL-4 and IL-13 at 4 months that were larger in the PTC arm (interactions p = 0.041 and p = 0.057, respectively). CONCLUSION: Improved SS was significantly associated with improved QOL independent of patient characteristics and study arm. Decreasing Th2 cytokines with increasing SS and QOL are consistent with a biobehavioral paradigm in which modulation of the chronic stress response is associated with shifts in immune stance.

Pain management at home in children with cancer: a daily diary study.

BACKGROUND: With the transition of care of cancer patients from the hospital to the home setting, parents are largely responsible for children's pain management. Children's cancer pain is undermanaged, yet, there is little empirical data on the occurrence and management of cancer pain in the home setting. The purpose of the present study, therefore, was to employ a daily diary protocol to examine barriers to pain management of children's cancer pain by parents at home. PROCEDURE: Parent-child dyads were recruited from the Cancer Institute at a major children's hospital in Southern California. A total of 45 patient/parent pairs completed baseline data on demographic and personality characteristics, children's quality of life, and parental beliefs regarding analgesic use for children and then completed daily diaries of pain and analgesic administration for 14 consecutive days. RESULTS: Most children were reported to experience chronic pain while undergoing treatment for cancer, yet overall analgesic administration at home was low. Parents who reported misconceptions regarding analgesic use for children were less likely to administer pain medication to children. Children who were less shy, more social, or had lower quality of life were more likely to receive analgesics. CONCLUSIONS: A significant proportion of children receiving outpatient treatment for cancer were rated as experiencing chronic pain and pain was not optimally managed in the home setting. Further understanding and addressing barriers to children's cancer pain management in the home setting will aid in alleviating unnecessary pain in this vulnerable patient population.

Illness uncertainty and quality of life in children with cancer.

BACKGROUND: Illness uncertainty is prevalent in children with cancer and has been associated with increased psychological distress. The relationship between illness uncertainty and quality of life in pediatric cancer patients remains unclear. The aim of the present study was to examine illness uncertainty as a predictor of health-related quality of life in children diagnosed with cancer. It was hypothesized that child-reported illness uncertainty would be negatively associated with child health-related quality of life. PROCEDURE: Children aged 8 to 18 years old and receiving treatment for cancer were recruited to participate in this study. One hundred twenty children and their parent(s) completed measures of illness uncertainty, pain, anxiety, and quality of life during a routine visit to the Cancer Center at Children's Hospital of Orange County. RESULTS: Illness uncertainty was significantly associated with child age (P=0.02), overall health-related (P<0.001) and cancer-related (P<0.001) quality of life, but not with treatment status (on/off chemotherapy) or demographic variables including sex and household income. Regression analyses statistically controlling for age, anxiety, and pain revealed that illness uncertainty significantly predicted child-reported cancer-related and health-related quality of life (P<0.01) as well as parent-reported cancer-specific quality of life (P<0.01). CONCLUSIONS: Illness uncertainty is prevalent and associated with lower quality of life in children diagnosed with cancer. Improved communication with children regarding disease state, treatment expectations, and prognosis may alleviate uncertainty and improve functioning in this vulnerable patient population.

Ethnicity and parental report of postoperative behavioral changes in children.

OBJECTIVES: To examine the role of ethnicity and language in parent report of children's postoperative behavioral recovery. AIM: To compare incidence of new onset negative behavior change in English- and Spanish-speaking White and Hispanic children following outpatient surgery. BACKGROUND: Postoperative behavioral change in children is common; however, it is unknown whether cultural variables including ethnicity and language may influence parent report of children's behavioral recovery. METHODS/MATERIALS: Participants included 288 parents (English-speaking White, English-speaking Hispanic, Spanish-speaking Hispanic parents) of children undergoing outpatient elective surgery. Parents completed the post-hospitalization behavior questionnaire (PHBQ) and parents' postoperative pain measure (PPPM) on postoperative days one, three, and seven at home. RESULTS: Most parents (83%) reported onset of new negative behavioral change in children postoperatively. Generalized estimating equations revealed significant group differences in overall behavior change [Wald χ(2)(12) = 375.69, P < 0.0001] after controlling for demographic and socioeconomic differences. At all three postoperative days, Spanish-speaking Hispanic (SSH) parents reported lower negative behavioral changes in their children compared to English-speaking White (ESW) parents (day 1: P < 0.01; day 3: P < 0.001; day 7: P < 0.10). On postoperative days one and three, SSH parents also reported lower total PHBQ scores than English-speaking Hispanic (ESH) parents [day 1: χ(2)(1) = 6.72, P = 0.01; day 3: χ(2)(1) = 7.98, P = 0.005]. CONCLUSION: The present study provides evidence that parent report of children's postoperative behavioral recovery may be influenced by cultural variables, such as ethnicity and language. The present results contribute to a growing body of evidence that highlights the need for culturally sensitive assessment and care of families in the medical setting. The findings may reflect differences in cultural values such as stoicism; however, future studies would benefit from examination of the factors that may account for the differences in reported behavior change after surgery (i.e., report bias, cultural values).

Attitudes regarding analgesic use and pain expression in parents of children with cancer.

BACKGROUND: Children with cancer often experience significant levels of pain and their pain is generally undermanaged. Management of care to patients with cancer has shifted from the hospital to the home, and as such parents are charged with managing children's pain. However, parents may have misconceptions of analgesic use, which can lead to undertreatment of pain in children. The purpose of this study is to examine attitudes toward pain medication and perceptions of pain expression among parents of children undergoing cancer treatment. PROCEDURE: Parents of children who were undergoing cancer treatment at a hospital were recruited to take part in a survey study. A total of 187 parents completed a survey examining their attitudes toward medication and perceptions of pain expression in children. RESULTS: Many parents reported concerns regarding analgesic use to treat their children's pain and misconceptions about how children can express pain. Regression analyses noted that parental perceptions of pain expression were related to children's experience of chronic or recurring pain and the 2 dimensions of child temperament: emotionality and sociability. CONCLUSIONS: Many parents of children with cancer have misconceptions regarding issues of pain management; these misconceptions can potentially lead to undertreatment of pain in children. These misconceptions are associated with aspects of children's temperament.

Desire for perioperative information and parental ethnicity.

OBJECTIVES: To examine the role of ethnicity, language, and socioeconomic variables in parental desire for information regarding children's surgery. AIM: To compare anesthetic and surgical information desired between English- and Spanish-speaking White and Hispanic mothers of children undergoing outpatient surgery. BACKGROUND: Parents report wanting to receive detailed information regarding children's preoperative care; however, variables such as parent ethnicity and language spoken have not been accounted for in understanding desire for information. METHODS/MATERIALS: One hundred and eighty-one mothers of children undergoing outpatient surgery, elective surgery, and general anesthesia were recruited and categorized into one of three groups: English-speaking White (ESW, n=79), English-speaking Hispanic (ESH, n = 63), and Spanish-speaking Hispanic (SSH, n = 39). In addition to providing demographic questionnaire, mothers completed the Parental Desire for Information (PDI) questionnaire, a 14-item measure of surgery and anesthesia-related statements. RESULTS: Overall, mothers desired receiving information about the majority of the items on the PDI. As compared to ESW mothers, SSH mothers and ESH mothers were overrepresented in the 'have a right to know' response option, with significant differences existing in items concerning alternative methods of anesthesia, details of needles used, and location of PACU and OR. CONCLUSIONS: Anesthesiologists should tailor the provision of preoperative information based on ethnicity and language of mothers involved. Ethnic and language differences shown in this study may exist in other populations as well.
