To assess feasibility and preliminary efficacy of a mobile/online-based (mHealth) mindfulness intervention for cancer patients and their caregivers to reduce distress and improve quality of life (QoL). Material and Methods: Twoarm randomized controlled trial within Kaiser Permanente Northern California targeting cancer patients who received chemotherapy and their informal caregivers. The intervention group received a commercially available mindfulness program for 8 weeks. The wait-list control group received usual care. We assessed feasibility using retention and adherence rates and obtained participant-reported data on distress, QoL, sleep, mindfulness, and posttraumatic growth before and immediately after the intervention. Results: Ninety-seven patients (median age 59 years; female 69%; 65% whites) and 31 caregivers (median age 63 years; female 58%; 77% whites) were randomized. Among randomized participants, 74% of the patients and 84% of the caregivers completed the study. Among those in the intervention arm who initiated the mindfulness program, 65% practiced at least 50% of the days during the intervention period. We observed significantly greater improvement in QoL among patients in the intervention arm compared with controls. Caregivers in the intervention group experienced increased mindfulness compared with controls. Participants appreciated the convenience of the intervention and the mindfulness skills they obtained from the program. Conclusion: We demonstrated the feasibility of conducting a randomized trial of an mHealth mindfulness intervention for cancer patients and their informal caregivers. Results from fully powered efficacy trials would inform the potential for clinicians to use this scalable intervention to help improve QoL of those affected by cancer and their caregivers.

Background & Aims Although patients with Barrett's esophagus commonly undergo endoscopic surveillance, its effectiveness in reducing mortality from esophageal/gastroesophageal junction adenocarcinomas has not been evaluated rigorously. Methods We performed a case-control study in a community-based setting. Among 8272 members with Barrett's esophagus, we identified 351 esophageal adenocarcinoma: 70 in persons who had a prior diagnosis of Barrett's esophagus (who were eligible for surveillance); 51 of these patients died, 38 as a result of the cancers (cases). Surveillance histories were contrasted with a sample of 101 living persons with Barrett's esophagus (controls), matched for age, sex, and duration of follow-up evaluation. Results Surveillancei within 3 years was not associated with a decreased risk of death from esophageal adenocarcinoma (adjusted odds ratio, 0.99; 95% confidence interval, 0.36–2.75). Fatal cases were nearly as likely to have received surveillance (55.3%) as were controls (60.4%). A Barrett's esophagus length longer than 3 cm and prior dysplasia each were associated with subsequent mortality, but adjustment for these did not change the main findings. Although all patients should be included in evaluations of effectiveness, excluding deaths related to cancer treatment and patients who failed to complete treatment, changed the magnitude, but not the significance, of the association (odds ratio, 0.46; 95% confidence interval, 0.13–1.64). Conclusions Endoscopic surveillance of patients with Barrett's esophagus was not associated with a substantially decreased risk of death from esophageal adenocarcinoma. The results do not exclude a small to moderate benefit. However, if such a benefit exists, our findings indicate that it is substantially smaller than currently estimated. The effectiveness of surveillance was influenced partially by the acceptability of existing treatments and the occurrence of treatment-associated mortality.

Stroke is rare among women of childbearing age. Low-estrogen oral-contraceptive preparations do not appear to increase the risk of stroke.
