Genetic and nongenetic covariates of pain severity in patients with adenocarcinoma of the pancreas: assessing the influence of cytokine genes.
We previously demonstrated that select cytokine gene polymorphisms in interleukin (IL)-8 are a significant predictor of pain and analgesia in patients with lung cancer. This study explores the role of 13 potentially functional polymorphisms in cytokine genes, including IL-1beta, IL-6, IL-8, IL-10, IL-18, tumor necrosis factor-alpha, and nuclear factor kappa-B subunit 1, in pain severity in patients with pancreatic cancer. We evaluated a series of patients with histologically confirmed adenocarcinoma of the pancreas (n=484), who had completed a self-administered survey of pain before initiating any cancer treatment. ⋯ When we adjusted for reported analgesic use, we found that IL8-251T/A persisted as a predictor for severe pain, with carriers of TT and AT genotypes having more than a threefold risk (OR=3.23, 95% CI=1.4, 4.7) for severe pain relative to the AA genotypes. We provide preliminary evidence of the role of IL-8 in the severity of pain in pancreatic cancer patients. Additional studies are needed in larger cohorts of patients.

Sleep-wake disturbances in patients with advanced cancer and their family carers.
Sleep disturbance is common in patients with advanced cancer, and their family carers also may suffer from sleep problems. The aims of this study were to determine the prevalence of sleep-wake disturbances in patients with advanced cancer and their carers, to monitor the amount of daytime spent in activity and rest, and to examine the relationship between sleep, physical, and psychological symptoms. This was a prospective, descriptive observational study in patients with advanced incurable cancer and their carers attending a regional cancer center, using subjective (Short Form-36, Epworth Sleepiness Score, Hospital Anxiety and Depression Scale, Memorial Symptom Assessment Scale, and sleep history and diary) and objective (Actiwatch) assessments over a seven-day period. ⋯ Objective measurements using Actiwatch revealed good SE but high levels of sleep fragmentation and movement, suggesting that sleep quality may be disturbed. Further work is required to investigate sleep quality and the consequences of poor sleep. In the meantime, health care professionals need to routinely inquire about sleep and consider possible reversible underlying factors, such as pain and anxiety, for those who report sleep disturbance.

Frequency and self-management of pain, dyspnea, and cough in cystic fibrosis.
Cystic fibrosis (CF) has been transformed from a fatal diagnosis in infancy to a chronic disease of children and young adults. Symptom patterns and disease burden in CF may be shifting to reflect the relatively healthier, older population with the disease. Self-management of symptoms is a hallmark of chronic illness, and yet we do not have a good understanding of how CF patients monitor or manage their symptoms. ⋯ A variety of pharmacological and nonpharmacological treatments were used to manage symptoms. Pain and dyspnea are more common than suspected and a wide variety of pharmacological and nonpharmacological measures are used to treat symptoms. Cough is difficult to assess, but disturbed sleep may be an indicator of cough severity and an important symptom to consider when evaluating the overall burden of illness in those with CF.

Breast cancer survivors' experiences of lymphedema-related symptoms.
As a serious chronic condition from breast cancer treatment, lymphedema or a syndrome of persistent swelling and symptoms is caused by chronic accumulation of lymph fluid in the interstitial spaces of the affected limb or surrounding areas. Although significant prevalence of ongoing multiple symptoms has been reported, little is known about how survivors with lymphedema perceive and respond to lymphedema-related symptoms in their daily lives. ⋯ Findings suggest that symptom distress may encompass temporal, situational, and attributive dimensions. Prospective studies are needed to examine lymphedema-related symptom distress in terms of these dimensions so that more specific interventions can be developed to target distress occurring in each dimension.

Mental health outcomes of family members of Oregonians who request physician aid in dying.
Oregon legalized physician aid in dying over 10 years ago but little is known about the effects of this choice on family members' mental health. We surveyed 95 family members of decedent Oregonians who had explicitly requested aid in dying, including 59 whose loved one received a lethal prescription and 36 whose loved one died by lethal ingestion. For comparison purposes, family members of Oregonians who died of cancer or amyotrophic lateral sclerosis also were surveyed. ⋯ Comparing family members of those who requested aid in dying to those who did not revealed no differences in primary mental health outcomes of depression, grief, or mental health services use. Family members of Oregonians who requested aid in dying felt more prepared and accepting of the death than comparison family members. In summary, pursuit of aid in dying does not have negative effects on surviving family members and may be associated with greater preparation and acceptance of death.
