Purpose: To describe physical activity (PA) trajectories across 10 years post-breast cancer diagnosis and examine their association with quality of life (QoL).
Methods: Participants from the longitudinal Study of Women's Health Across the Nation who developed incident breast cancer completed the Quality of Life in Adult Cancer Survivors scale (QLACS) which has 12 domains. Breast cancer survivors (BCS) with at least one post-diagnosis measure of the Kaiser Physical Activity Survey (PA) were included (n = 96).
Article Synopsis
- Women may experience significant changes in depressive symptoms during the menopause transition, particularly around the final menstrual period (FMP).
- A study involving over 1,500 multiracial women tracked depressive symptoms over time, noting that those with high initial symptoms tended to improve until four years before the FMP, while those with low symptoms experienced an increase until a year before the FMP.
- Factors such as social support and hormonal levels were linked to decreases in symptoms, while anxiety and stressful life events predicted increases in depressive symptoms among those initially reporting low symptoms.
Work in compressed air and diving are both occupational activities that have been around since the mid-19th century, and those undertaking their work under elevated pressure. Meeting the demand to go to "higher pressure for longer" in tunneling has lagged in diving, but both activities have found it necessary to adopt mixed gas breathing and saturation exposure techniques. This paper explains how work in hyperbaric conditions at high pressure is undertaken in tunneling and is illustrated by the hyperbaric activity likely to be involved in constructing a large-diameter road tunnel below a body of water such as an estuary.

The maximum pressure was 253 kPa gauge with oxygen decompression using the Swanscombe Oxygen Decompression Table. He was found to have a very large right-to-left shunt across a 9 mm atrial septal defect.

The Lachman, anterior drawer, Lever, and pivot shift tests are all greater than 90% specific for ACL pathology. Due to the relatively high coincidence of ACL injuries and those to the posterior cruciate ligament, posterolateral corner , posteromedial corner , and menisci, it is critical that the examiner perform provocative maneuvers to evaluate the integrity of these structures as well.
